The fault indicator of the distribution line can be used to indicate the short-circuit fault and ground fault of the distribution line. By using a fault indicator, it is possible to flag the section of the distribution line where a fault occurs. The operation and maintenance personnel can quickly find the faulty section according to the alarm signal of the fault indicator, and disconnect the faulty section, so as to restore the power supply of the non-faulty section in time, which can save a lot of working time and reduce the power outage time and power outage scope.

It can be seen that whether the communication of the fault indicator is normal or not directly affects the analysis result of the fault section. At present, the operation and maintenance personnel on the main station side judge whether the communication of the fault indicator is normal or not by checking whether the fault indicator is online. However, the fault indicator includes a collection unit and a collection unit inside, and its communication can be divided into two parts, one part is from the collection unit to the collection unit, and the other is from the collection unit to the master station. When the communication between the collection unit and the collection unit is abnormal, the telemetry message and telesignal message of the collection unit cannot be uploaded to the collection unit, then when the distribution line corresponding to the fault indicator fails, although the fault indicator is online, However, the master station side cannot receive telemetry messages and remote signaling messages, resulting in the operation and maintenance personnel being unable to correctly determine the faulty section after a fault, which greatly reduces the repair efficiency and prolongs the repair time for restoring power supply.

detailed description

Hereinafter, the present application will be described in detail with reference to the drawings and embodiments. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

In this embodiment, a method for detecting an abnormal internal communication of a fault indicator is provided, as shown in FIG. 1 , the method includes:

Step 101, receiving a message sent by a collection unit in any fault indicator, and identifying a remote signaling message and a telemetry message from the message;

Each fault indicator can include a three-phase acquisition unit and a collection unit. As shown in Figure 2, micro-power wireless communication can be realized between the three-phase acquisition unit and the collection unit, and between the collection unit and the distribution automation master station. Wireless or fiber optic communication. The method for detecting abnormal internal communication of the fault indicator provided by the embodiment of the present application can be specifically applied to the control terminal on the master station side, and can be used to detect between the internal acquisition unit (three-phase acquisition unit) and the collection unit of the fault indicator Whether the communication is abnormal. If the communication between the collection unit and the collection unit is abnormal, the remote signaling message and telemetry message sent by the collection unit will not be sent to the control terminal on the master station side through the collection unit, or there will be a remote signaling message or telemetry message In case of absence, the control end cannot judge the fault section in the distribution line. In the method for detecting an abnormal internal communication of the fault indicator in the embodiment of the present application, all the fault indicators established on the master station side can be detected in real time. Firstly, any message sent by the collection unit in any fault indicator can be received, wherein the message can include a heartbeat message, a remote signaling message, a telemetry message, and the like. From this, telematics messages and telemetry messages can then be identified.

Step 102, performing message analysis on the remote signaling message and the telemetry message, and updating the internal communication abnormality level and flag bit corresponding to any fault indicator based on the analysis results;

In this embodiment, the received telematics message and telemetry message can be analyzed respectively. After that, the internal communication abnormal level and flag bit corresponding to the fault indicator can be updated according to the analysis result of the telemetry message, and the internal communication abnormal level and flag bit corresponding to the fault indicator can also be updated according to the analysis result of the telemetry message. renew. Among them, the internal communication exception level and the flag bit are global variables. For example, the internal communication anomaly level has just been updated according to the analysis result of the telemetry message, and the update result is obtained. At this time, the analysis result of the telemetry message also meets the update condition of the internal communication anomaly level, so you can update the result based on the update result. Make an update again.

Step 103, when the updated internal communication abnormal level reaches the preset level threshold, judge whether the flag bit corresponding to any of the fault indicators is a specified value, and if it is not a specified value, determine whether any of the fault indicators Internal communication is abnormal.

In this embodiment, after each update of the internal communication abnormality level, a comparison may be made between the updated internal communication abnormality level and a preset level threshold. If after comparison, it is found that the abnormal level of internal communication is greater than or equal to the preset level threshold, it can be further judged at this time whether the flag bit corresponding to the fault indicator is a specified value. If it is not the specified value, then the internal communication of the fault indicator can be determined. There is an exception.

By applying the technical solution of this embodiment, firstly, the message sent by the converging unit in any fault indicator can be received, and the remote signaling message and the telemetry message can be identified therefrom. Then, the received telematics message and telemetry message can be analyzed respectively. After that, the internal communication abnormal level and flag bit corresponding to the fault indicator can be updated according to the analysis result of the telemetry message, and the internal communication abnormal level and flag bit corresponding to the fault indicator can also be updated according to the analysis result of the telemetry message. renew. After updating the internal communication abnormality level each time, a comparison may be made between the updated internal communication abnormality level and a preset level threshold. If after comparison, it is found that the abnormal level of internal communication is greater than or equal to the preset level threshold, it can be further judged at this time whether the flag bit corresponding to the fault indicator is a specified value. If it is not the specified value, then the internal communication of the fault indicator can be determined. There is an exception. The embodiment of the present application does not need to increase the hardware cost, and the judgment of whether the internal communication of the fault indicator is abnormal can be realized through the original control terminal on the main station side, which is simple and convenient, and can greatly improve the stability and reliability of the fault indicator.

Further, as a refinement and expansion of the specific implementation of the above-mentioned embodiment, in order to fully describe the specific implementation process of this embodiment, another detection method for abnormal internal communication of the fault indicator is provided, as shown in Figure 3, the method include:

Step 201, receiving a message sent by a collection unit in any fault indicator, and identifying a remote signaling message and a telemetry message from the message;

In this embodiment, firstly, the message sent by the converging unit in any fault indicator can be received, and the remote signaling message and the telemetry message can be identified therefrom.

Step 202, performing message analysis on the remote signaling message and the telemetry message, and updating the internal communication abnormality level and flag bit corresponding to any fault indicator based on the analysis results;

In this embodiment, then, the received telematics message and telemetry message can be analyzed respectively. After that, the internal communication abnormal level and flag bit corresponding to the fault indicator can be updated according to the analysis result of the telemetry message, and the internal communication abnormal level and flag bit corresponding to the fault indicator can also be updated according to the analysis result of the telemetry message. renew.

Step 203, when the updated internal communication abnormality level reaches the preset level threshold, output the ledger information of any fault indicator;

In this embodiment, after each update of the internal communication abnormality level, a comparison may be made between the updated internal communication abnormality level and a preset level threshold. If it is found through comparison that the internal communication abnormality level is greater than or equal to the preset level threshold, then the ledger information corresponding to the fault indicator may be output. Wherein, the ledger information may include relevant information such as id, manufacturer, model and installation location of the fault indicator. In this way, the operation and maintenance personnel can quickly locate the corresponding fault indicator according to the received ledger information.

Step 204, judge whether the flag bit corresponding to any of the fault indicators is a specified value, and if it is not a specified value, determine that the internal communication of any of the fault indicators is abnormal; when it is a specified value, determine that any of the fault indicators Whether the fault indicator is mounted on the unloaded line, and if it is not mounted on the unloaded line, it is determined that the internal communication of any fault indicator is abnormal.

In this embodiment, it can be further judged whether the flag bit corresponding to the fault indicator is a specified value, and if not, it can be determined that the internal communication of the fault indicator is abnormal. If it is a specified value, it can be judged whether the fault indicator is mounted on the unloaded line, if the fault indicator is not mounted on the unloaded line, it can also be concluded that the internal communication of the fault indicator exists abnormal. Whether it is determined that there is an abnormality in the internal communication of the fault indicator, or that the fault indicator is mounted on an unloaded line, the operation and maintenance personnel can quickly locate the corresponding fault indicator according to the ledger information of the fault indicator output in step 203 , and know the manufacturer of the fault indicator and other related information. In the embodiment of the present application, by setting the global variable of the flag bit, it is not necessary to determine which fault indicators are mounted on the no-load line before the fault indicator is used, and then when the updated internal communication abnormality level reaches the preset level When the threshold is reached, it is more convenient to determine the real cause of the updated internal communication abnormal level reaching the preset level threshold according to the corresponding flag bit of the fault indicator; When the level threshold is preset, the ledger information of the fault indicator is output, which is convenient for the operation and maintenance personnel to quickly locate the fault indicator that has a problem, reduces the troubleshooting time, and improves the troubleshooting efficiency.

In this embodiment of the present application, optionally, the "analyze the remote signaling message and update the internal communication abnormality level corresponding to any fault indicator based on the analysis result" in step 202 includes : Based on the first preset number of continuous remote signaling messages, determine the message combination corresponding to the continuous remote signaling messages, the message combination is composed of fault remote signaling and/or reset remote signaling; according to the message combination , to determine whether the message combination is composed of the fault remote signaling and the reset remote signaling alternately; when the result is no, update the internal communication abnormality level corresponding to any fault indicator; when the result is If so, restore the internal communication abnormality level corresponding to any fault indicator to the first initial value.

In this embodiment, if the communication between the acquisition unit and the collection unit is normal, the remote signaling message received by the control terminal at the master station side should be a repetition of a failure remote signaling + a reset remote signaling. Therefore, in order to determine whether the communication between the acquisition unit and the collection unit is normal from the perspective of remote signaling messages, the first preset number of continuous remote signaling messages can be used as the basis to determine the number of messages contained in these continuous remote signaling messages What is the combination, that is, how the fault remote signaling and reset remote signaling are arranged in these continuous remote signaling messages. Under normal circumstances, the arrangement should be: fault remote signaling + reset remote signaling + fault remote signaling + reset remote signaling... If the combination of messages in the continuous remote signaling messages is not in the above form, it means that there is a loss of remote signaling messages At this time, the internal communication abnormal level corresponding to the fault indicator sending the remote signaling message can be updated once. Specifically, 1 can be added to the original internal communication abnormal level, that is, it will be upgraded to one level; if continuous remote signaling The message combination in the article is in the above form, so it shows that the communication between the acquisition unit and the collection unit is normal. At this time, the internal communication abnormality level corresponding to the fault indicator sending the remote signaling message can be restored to the first initial value. An initial value is the initial value of the internal communication abnormality level. For example, the first preset number is 4, then the message combination can be determined from the received 4 consecutive remote signaling messages, if the message combination is "fault remote signaling + reset remote signaling + fault remote signaling + reset remote signaling" , or "reset remote signal + fault remote signal + reset remote signal + fault remote signal", then the communication between the acquisition unit and the collection unit in the fault indicator is normal; When it is "reset remote signal + fault remote signal + reset remote signal + reset remote signal", etc., it means that there is a lack of remote signal message, that is, there is a gap between the acquisition unit and the collection unit in the fault indicator. abnormal communication.

In this embodiment of the present application, optionally, after the "update the internal communication abnormality level corresponding to any fault indicator", the method further includes: when the updated internal communication abnormality level does not reach When the preset level threshold is reached, update the first preset number of continuous remote signaling messages according to the first preset rule, and return to the step of determining the message combination corresponding to the continuous remote signaling messages ;

After the "restore the internal communication abnormality level corresponding to any fault indicator to the first initial value", the method further includes: when the updated internal communication abnormality level does not reach the preset level threshold, According to a second preset rule, update the first preset number of continuous remote signaling messages, and return to the step of determining the message combination corresponding to the continuous remote signaling messages.

In this embodiment, after the internal communication abnormality level corresponding to the fault indicator is updated once, if the updated internal communication abnormality level does not reach the preset level threshold compared with the preset level threshold, then the The first preset rule is to update the above-mentioned first preset number of continuous remote signaling messages. Specifically, the first preset rule may be: use the newly received remote signaling message to update the remote signaling message with the earliest reception time among the first preset number of consecutive remote signaling messages. For example, the first preset number is 4, and the corresponding continuous remote signaling messages are respectively remote signaling message 1, remote signaling message 2, remote signaling message 3, and remote signaling message 4, wherein the remote signaling message 1 The receiving time is the earliest, and the receiving time of the remote signaling message 4 is the latest, so when updating the first preset number of continuous remote signaling messages, the newly received remote signaling message 5 can be added, and the remote signaling message 5 can be removed. In this way, the updated continuous remote signaling messages are respectively remote signaling message 2, remote signaling message 3, remote signaling message 4, and remote signaling message 5. After updating the first preset number of continuous remote signaling messages, return to the step of determining the message combination corresponding to the continuous remote signaling messages until the updated internal communication abnormality level reaches the preset level threshold.

In addition, after the internal communication abnormality level corresponding to the fault indicator is restored to the first initial value, if the updated internal communication abnormality level does not reach the preset level threshold compared with the preset level threshold, then you can follow the first The second preset rule is to update the above-mentioned first preset number of continuous remote signaling messages. Specifically, the second preset rule may be: delete all the previous first preset number of continuous remote signaling messages, and acquire a new first preset number of continuous remote signaling messages. For example, the first preset number is 4, and the corresponding continuous remote signaling messages are respectively remote signaling message 1, remote signaling message 2, remote signaling message 3, and remote signaling message 4, then for the first preset When a number of consecutive remote signaling messages are updated, all remote signaling messages 1 to 4 can be deleted at this time, and the newly received remote signaling messages 5 to 8 can be used to update the previous Continuous remote signaling messages. After updating the first preset number of continuous remote signaling messages, return to the step of determining the message combination corresponding to the continuous remote signaling messages until the updated internal communication abnormality level reaches the preset level threshold.

In this embodiment of the present application, the first preset number of continuous telematics messages are updated by using the first preset rule and the second preset rule, which can reduce outdated data storage and resource occupation.

In the embodiment of the present application, optionally, in step 202, "analyze the telemetry message, and update the internal communication abnormality level and flag bit corresponding to any fault indicator based on the analysis result" , comprising: based on a second preset number of continuous telemetry messages, determining a matching degree between the continuous telemetry messages and preset conditions, where the telemetry messages include three-phase current values; when the continuous telemetry messages contain When the third preset number of telemetry messages meets the first preset condition, the internal communication abnormality level corresponding to any fault indicator is updated once, and the first preset condition is that among the three-phase current values There is one phase current value or two phase current values are zero, and the remaining phase current value is higher than the preset current threshold; when there is a fourth preset number of telemetry messages in the continuous telemetry messages that meet the second preset condition, updating the flag bit corresponding to any of the fault indicators to a specified value, and updating the internal communication abnormality level corresponding to any of the fault indicators, and the second preset condition is that the three-phase current values are Zero; when there are at least a fifth preset number of telemetry packets in the continuous telemetry packets that meet the second preset condition, and when there are telemetry packets that do not meet the second preset condition, restore the flag bit to The second initial value is locked, and the internal communication abnormality level corresponding to any fault indicator is updated once.

In this embodiment, in order to determine whether the communication between the acquisition unit and the collection unit is normal from the perspective of the telemetry messages, it is possible to determine the difference between the continuous telemetry messages and the preset condition based on the second preset number of continuous telemetry messages. The degree of matching between them is used to determine whether to update the abnormal level and flag bits of the internal communication of the fault indicator. Wherein, the telemetry message may include three-phase current values, and the foregoing preset conditions may include a first preset condition and a second preset condition. The first preset condition is that among the three-phase current values, one phase current value or two phase current values are zero, and the remaining phase current values are higher than the preset current threshold value; the second preset condition is that the three-phase current values are all zero. When the first preset condition is met, it indicates that some phase telemetry messages in the group of three-phase telemetry messages are lost, so it is an internal communication abnormality; when the second preset condition is met, it indicates that the group of three-phase telemetry messages may be abnormal, and there is a telemetry The message is lost, and the fault indicator may also be mounted on the unloaded line.

If a third preset number of telemetry messages among the second preset number of continuous telemetry messages satisfy the first preset condition, then the internal communication abnormality level corresponding to the fault indicator can be updated once. For example, the second preset number is 5, and the third preset number is 3. If 3 sets of telemetry messages in 5 sets of continuous telemetry messages meet the first preset condition, then the internal The level of communication abnormality is raised by one level. Wherein, the preset current threshold in the first preset condition may specifically be 10A.

If there is a fourth preset number of telemetry messages in the second preset number of continuous telemetry messages that meet the second preset condition, then the flag bit corresponding to the fault indicator can be updated to a specified value, and at the same time The internal communication abnormal level corresponding to the fault indicator can be updated once. For example, the second preset number is 5, the fourth preset number is 5, and the specified value of the flag bit is 1, that is, if all 5 groups of continuous telemetry messages meet the second preset condition, then the fault indicator can be The corresponding flag bit is updated to 1, and at the same time, the internal communication abnormal level corresponding to the fault indicator is raised to one level.

If there are at least the fifth preset number of telemetry messages in the second preset number of continuous telemetry messages that meet the second preset condition, and there are telemetry messages that are not satisfied with the second preset condition, then at this time, the The flag bit corresponding to the fault indicator returns to the second initial value, and at the same time, it can be locked after returning to the second initial value so that it will not change in the future. At the same time, the corresponding fault indicator can also be An update of the internal communication exception level. Here, the second initial value is the initial value corresponding to the flag bit. For example, the second preset number is 5, the fifth preset number is 3, and the second initial value is 0, then if at least 3 sets of telemetry messages in 5 sets of continuous telemetry messages meet the second preset condition, and at least When one group of telemetry messages does not meet the second preset condition, then the internal communication abnormality level corresponding to the fault indicator can be upgraded to one level, and at the same time, the flag bit can be restored to 0 and locked.

Before the fault indicator is put into use, the internal communication abnormal level can be set to the first initial value, and the flag position can be set to the second initial value.

In the embodiment of the present application, after "updating the internal communication abnormality level corresponding to any fault indicator", the method further includes: when the updated internal communication abnormality level does not reach the preset When the level threshold is reached, update the second preset number of continuous telemetry packets according to a third preset rule, and return to the step of determining the matching degree between the continuous telemetry packets and the preset condition.

In this embodiment, no matter which preset condition is satisfied by the second preset number of continuous telemetry messages, as long as the internal communication abnormality level is updated, the difference between the updated internal communication abnormality level and the preset level threshold can be judged. size relationship between them. If it is determined that the updated internal communication abnormality level is lower than the preset level threshold, then the second preset number of continuous telemetry messages may be updated according to the third preset rule. Specifically, the third preset rule may be: delete all the previous second preset number of continuous telemetry messages, and acquire a new second preset number of continuous telemetry messages. For example, the second preset number is 5, and the corresponding continuous telemetry messages are respectively telemetry message 1, telemetry message 2, telemetry message 3, telemetry message 4, and telemetry message 5, then the second preset When a number of continuous telemetry messages are updated, all telemetry messages 1 to 5 can be deleted at this time, and newly received telemetry messages 6 to 10 are used to update the previous continuous telemetry messages. After updating the second preset number of continuous telemetry messages, return to the step of determining the matching degree between the continuous telemetry messages and the preset conditions, and end when the updated internal communication abnormality level reaches the preset level threshold. In this embodiment of the present application, the third preset rule is used to update the second preset number of continuous telemetry messages, which can reduce outdated data storage and reduce resource occupation.

In this embodiment of the present application, optionally, the method further includes: when there is a sixth preset number of telemetry packets in the continuous telemetry packets that meet the third preset condition, outputting an alarm of abnormal telemetry data, and updating The second preset number of continuous telemetry messages, and return to the step of determining the matching degree between the continuous telemetry messages and the preset condition, the third preset condition is the maximum of the three-phase current values value, greater than a preset multiple of the minimum value of the three-phase current values, and does not satisfy the first preset condition.

In this embodiment, the preset conditions may further include a third preset condition. Wherein, the third preset condition is: the maximum value of the three-phase current values is greater than a preset multiple of the minimum value of the three-phase current values, and at the same time, the first preset condition cannot be satisfied. For example, if the preset multiple is 10, then the third preset condition is max{I _a , I _b , I _c }>10min{I _a , I _b , I _c }, and the first preset condition is not satisfied. If the third preset condition is satisfied, it indicates that the internal communication of the fault indicator is normal, but the telemetry data is abnormal. If there is a sixth preset number of telemetry messages in the second preset number of continuous telemetry messages that meet the third preset condition, an abnormal telemetry data alarm can be output at this time to remind the operation and maintenance personnel to find the cause of the abnormal telemetry data . For example, if the second preset number is 5, and the sixth preset number is also 5, then when the 5 sets of continuous telemetry data all meet the third preset condition, an alarm of abnormal telemetry data can be output at this time. After that, the second preset number of continuous telemetry messages can be updated according to the third preset rule, and return to the step of determining the matching degree between the continuous telemetry messages and the preset conditions until the updated internal communication abnormality level Ends when the preset rating threshold is reached. In the embodiment of the present application, by setting the third preset condition, it can effectively determine the situation that the internal communication of the fault indicator is normal but the telemetry data is abnormal, which is beneficial to help the operation and maintenance personnel to quickly analyze and improve the analysis efficiency.

Further, the embodiment of the present application provides another method for detecting abnormal internal communication of the fault indicator, as shown in FIG. 4 , the method includes:

Firstly, read all fault indicator lists of established graphs on the master station side, and determine each fault indicator in the fault indicator list. Next, set the initial value (ie, the first initial value) of the abnormality level (internal communication abnormality level) R of each fault indicator to 0, and set the initial value (ie, the second initial value) of the flag bit F to 0. The control terminal at the master station side can receive the message sent by the terminal (fault indicator) frame by frame, where the message includes a telesignal message and a telemetry message. After receiving the message, the remote signaling message and the telemetry message can be analyzed respectively. For remote signaling messages, two sets of remote signaling data can be continuously stored in FIFO mode, and then it can be judged whether the two sets of continuous remote signaling data is a repeated way of fault remote signaling + reset remote signaling, if not, then you can make R=R+1, update the abnormality level, if yes, set R=0, and clear two consecutive sets of remote signaling messages. For telemetry messages, five sets of telemetry data can be continuously stored in FIFO mode, and then the matching of five sets of telemetry data with various conditions can be judged. Wherein, condition A (the first preset condition) is: the three-phase current value has one phase current value or two phase current values are 0, and the remaining phase current value is higher than the threshold value I0=10A; Condition B (the second preset condition ) is: the three-phase current values are all 0; the condition C (the third preset condition) is: when the condition A is not satisfied, and the three-phase current values satisfy max{I _a , I _b , I _c }>10min{I _a , I _b , I _c }. If three of the five sets of continuous telemetry data meet condition A, then R=R+1 can be set to update the abnormal level; if all five sets of continuous telemetry data meet condition B, then R=R+1 can be set, and F is set to 1; if at least three of the five sets of continuous telemetry data meet condition B, and not all of them meet condition B, then R=R+1 can be set, and F is set to 0 and then no longer set to 1; if five If the group of continuous telemetry data all satisfies condition C, then an alarm for abnormal telemetry data can be output. After that, 5 sets of continuous telemetry data can be cleared. Whenever the abnormality level is updated, it can be judged whether the updated abnormality level is greater than or equal to 10. If so, the ledger information of the corresponding fault indicator can be printed, and further judge whether the flag bit is equal to 1. If the flag bit is equal to 1 , then you need to print and confirm whether the fault indicator is mounted on the no-load line, so as to judge whether the abnormality level greater than 10 is caused by the fault indicator being hung on the no-load line; if the flag bit is not equal to 1, then you can The communication between the printing terminal (fault indicator) collection unit and the collection unit is abnormal. If the updated abnormal level is less than 10, then return to the step of receiving the message frame by frame at the control terminal at the master station side. Among them, the dynamic storage of telemetry messages and remote signaling messages can be realized by means of FIFO, which is beneficial to the reduction of occupied resources.

Further, as a specific implementation of the method in Figure 1, the embodiment of the present application provides a device for detecting abnormal internal communication of a fault indicator, as shown in Figure 5, the device includes:
