Description

Measurement system for current and resistance data associated with target facility {MEASUREMENT SYSTEM FOR CURRENT AND RESISTANCE DATA ASSOCIATED WITH TARGET FACILITY}

The present disclosure relates to a measurement system for current and resistance data associated with a target facility, and more particularly, to a system for measuring grounding resistance, insulation resistance or leakage current of electric poles, towers, transformers, various electrical and railway facilities, etc.

Grounding is the intentional connection of an appropriate part of equipment such as a pole, tower, transformer, electrical facility, or railway facility to the ground. This is to ensure human safety by safely channeling hazardous current to the ground in the event of a leakage or accident, or to ensure reliable operation of equipment by eliminating noise. Grounding resistance refers to the ratio of the increase in ground potential to the ground current when grounding current flows into the grounding electrode.

Insulation refers to a state in which current cannot flow. Resistance also refers to a component that impedes the flow of current, and insulation resistance refers to the resistance of the path through which current flows through the insulator to another charged part or metal. If the insulation resistance is high, current cannot flow easily, and if the insulation resistance is low, current can flow easily. Insulation resistance is a resistance value that indicates the condition of an insulating material, such as an insulator or the coating of a wire. A high insulation resistance value may indicate a good insulating material, while a low insulation resistance value may indicate a poor insulating material. Insulation resistance is one of the important parameters in electrical circuits, and it indicates the degree to which electricity can flow safely without leakage in an electrical device or system.

Simply put, insulation resistance can be thought of as a measure of the effectiveness of the "film" that prevents unwanted leakage of electricity in an electrical circuit. This "film" is the insulating material between wires or components, effectively blocking electricity and ensuring safe operation.

For example, when the wires or components of an electrical device have different voltages, high insulation resistance prevents electricity leakage, ensuring safe operation. However, low insulation resistance can lead to electricity leakage, potentially posing a safety risk.

Therefore, insulation resistance is one of the important factors in evaluating the safety of electrical devices, and must be carefully measured and maintained to build a safe electrical system.

Leakage current refers to the leakage of current. While this is not a problem if current flows through normal condensation, it can be problematic if it flows through other paths, which is why leakage current measurement is necessary. All electrical equipment is insulated to prevent electricity from leaking out. However, if the insulation is old or damaged, its resistance decreases, allowing significant current to escape. Therefore, leakage current is a crucial indicator of a conductor's insulating effectiveness.

Devices such as poles, towers, transformers, electrical facilities, and railway facilities are installed to supply electricity, communications, and broadcasting via wired connections. These devices are responsible for supplying and managing all electricity. Pole, towers, transformers, electrical facilities, and railway facilities typically connect to the poles at their highest point and include overhead and buried ground lines whose ground resistance must be legally measured. These overhead and buried ground lines are connected to grounding devices to protect distribution equipment from abnormal currents (such as lightning, ground faults, and surges) and prevent various electrical hazards caused by leakage currents. Therefore, ground resistance can be measured.

However, because overhead ground lines are located at the top of utility poles or towers, measuring ground resistance through overhead ground lines requires workers to climb onto the transformers on the poles or towers, which poses a potential safety hazard. Conversely, because buried ground lines are bare conductors laid underground, measuring ground resistance through buried ground lines requires a significant amount of work.

In the present disclosure, a measurement system for current and resistance data associated with a target facility can be implemented with a master node, multiple slave nodes, and a control server.

The master node and multiple slave nodes can be grouped according to predefined zones. The master node and multiple slave nodes can share a valid range for measurement data. In other words, the master node and multiple slave nodes can be grouped together by nodes whose measurement data has the same or similar valid range within the predefined zone. Here, the measurement data can be ground resistance, insulation resistance, or leakage current, etc.

A grouped master node and multiple slave node groups can share measurement data. The shared measurement data can be transmitted to a control server by the master node. Accordingly, the control server can determine a target facility where an anomaly has occurred based on the measurement data received from the master node. Here, the target facility may be a utility pole, a tower, a transformer, an electrical facility, or a railway facility. Hereinafter, an example of a measurement system for current and resistance data associated with a target facility according to the present disclosure will be described with reference to FIGS. 1 to 5 .

FIG. 1 illustrates an exemplary system of a measurement system for current and resistance data associated with a target facility according to some embodiments of the present disclosure.

Referring to FIG. 1, a measurement system (1000) for current and resistance data associated with a target facility may include a master node (100), a plurality of slave nodes (200), and a control server (300). However, the above-described components are not essential for implementing the grounding resistance measurement system (1000), and thus the measurement system (1000) may have more or fewer components than the components listed above.

The master node (100) may be a grounding resistance, insulation resistance, or leakage current meter. The master node (100) may include any type of computer system or computer device, such as a portable device or device controller. The master node (100) may be installed in a device such as a pole, tower, transformer, electrical facility, or railway facility where a grounding wire is embedded.

The master node (100) can receive transmission information including measurement data measuring ground resistance, insulation resistance, or leakage current from at least one slave node among a plurality of slave nodes (200) via a first communication protocol. The first communication protocol can also be used for communication between the plurality of slave nodes (200). The master node (100) can transmit report information including transmission information to the control server (300) via a second communication protocol.

Here, the first communication protocol may be a protocol utilizing a short-range communication network. For example, the first communication protocol may be Bluetooth Low Energy communication or Bluetooth communication. The second communication protocol may be a protocol utilizing a long-range communication network. For example, the second communication protocol may be a communication protocol utilizing Narrow Band-Internet of Things (NB-IoT). Since communication between multiple slave nodes (200) or communication between at least one slave node and a master node (100) is performed using the first communication protocol, and communication between the master node (100) and the control server (300) is performed using the second communication protocol, the measurement system (1000) can have reduced maintenance costs.

Specifically, the second communication protocol may be a communication protocol that incurs communication costs, while the first communication protocol may be a communication protocol that does not incur communication costs. Accordingly, the communication costs for maintaining the measurement system (1000) may be reduced. Furthermore, since only the master node (100) is implemented to enable narrowband Internet of Things and low-power Bluetooth communication, while the multiple slave nodes (200) are implemented to enable only Bluetooth communication, the initial cost for constructing the measurement system (1000) may also be reduced.

In addition, both low-power Bluetooth communication and narrowband IoT can be maintained at low power. In other words, the replacement cycle for replacing the batteries of the master node (100) and multiple slave nodes (200) can also be longer. The shorter the battery replacement cycle, the more frequently workers may have to climb onto and come into contact with target facilities such as electric poles, towers, transformers, electrical facilities, or railway facilities. This can be a factor that increases the probability of an accident occurring. On the other hand, since the communication between the master node (100) and multiple slave nodes (200) according to the present disclosure is all performed using low-power communication, the labor cost incurred for battery replacement, the risk of accidents by workers for battery replacement, and the cost of battery replacement can all be reduced.

The master node (100) may include a control unit (110), a storage unit (120), and a communication unit (130). Additionally, the master node (100) may further include a replaceable battery.

The control unit (110) can typically process the overall operation of the master node (100). The control unit (110) can process signals, data, information, etc. input or output through components of the master node (100) or transmit report information to the control server (300) by running an application program stored in the storage unit (120).

The control unit (110) may be composed of one or more cores and may include a processor for data analysis, such as a central processing unit (CPU).

The storage unit (120) may include memory and/or a permanent storage medium. The memory may include at least one type of storage medium among a flash memory type, a multimedia card micro type, a card type memory (e.g., an SD or XD memory, etc.), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), or a programmable read-only memory (PROM).

The communication unit (130) may include one or more modules that enable communication between the master node (100) and the communication system, between the master node (100) and multiple slave nodes (200), or between the master node (100) and the control server (300).

The plurality of slave nodes (200) may be ground resistance, insulation resistance, or leakage current meters. The plurality of slave nodes (200) may include any type of computer system or computer device, such as a portable device or device controller. The plurality of slave nodes (200) may be installed in target facilities such as electric poles, towers, transformers, electrical facilities, or railway facilities, where ground lines are buried through overhead lines.

A plurality of slave nodes (200) can each collect measurement data, such as grounding resistance, insulation resistance, or leakage current, associated with a designated target facility. In other words, at least one slave node (200) is installed per target facility, and can collect measurement data associated with the installed target facility.

A plurality of slave nodes (200) may include a control unit, a storage unit, a communication unit, and a battery.

A master node (100) and a plurality of slave nodes (200) may be grouped according to a pre-designated area. The master node (100) and a plurality of slave nodes (200) may share a valid range for measurement data. In other words, the master node (100) and a plurality of slave nodes (200) may be grouped together with nodes whose measurement data has the same or similar valid range within a pre-designated area.

Target facilities may include power poles, towers, transformers, electrical facilities, or railway facilities. Examples of target facilities are shown in Table 1 below.

Jeonju pylon railway facilities
Electricity supply system including electric power facilities and transmission and substation facilities
Equipment for supplying electricity to overhead lines Tramway facilities A catenary wire that supplies power by directly contacting the train's current collector (pantograph), and the supports and auxiliary equipment installed to support it. power facilities This is a facility that supplies electricity to railway facilities excluding train operation power, and is classified into facilities that supply electricity to various trackside equipment (signals, communications, etc.) and facilities that supply electricity to station facilities (lighting, station facilities, computer equipment, etc.). Original equipment Remote control equipment (SCADA System, Supervisory Control And Data Acquisition)
A system that remotely monitors and controls the operation information of power supply facilities such as substations and tram lines of the national railway network in real time from the Railway Traffic Control Center.

The control server (300) may include any type of computer system or computer device, such as, for example, a microprocessor, a mainframe computer, a digital processor, a portable device, or a device controller. The control server (300) may achieve desired system performance using a combination of typical computer hardware (e.g., devices that may include computer processors, memory, storage, input devices and output devices, and other components of conventional computing devices; electronic communication devices such as routers, switches, and the like; electronic information storage systems such as network-attached storage (NAS) and storage area networks (SAN)) and computer software (i.e., instructions that cause the computing device to function in a particular manner).

The control server (300) can receive report information including transmission information from the master node (100) via the second communication protocol. Based on the report information, the control server (300) can determine the first target facility where measurement data that falls outside the valid range appears. Hereinafter, an example of a method by which the control server (300) according to the present disclosure determines the first target facility where measurement data that falls outside the valid range appears will be described with reference to FIG. 2.

FIG. 2 is a flowchart illustrating an example of a method by which a control server according to some embodiments of the present disclosure determines a first target facility where measurement data that is out of range appears.

Referring to FIG. 2, a plurality of slave nodes (200) are each installed in a designated target facility and can collect measurement data on current and resistance associated with the installed target facility (S110). Here, the measurement data may be grounding resistance, insulation resistance, leakage current, etc.

Each of the plurality of slave nodes (200) may transmit transmission information including measurement data to each other or to the master node (100) via the first communication protocol. Here, the transmission information may include measurement data and a node identifier. For convenience of explanation, reference may be made to FIG. 3.

FIG. 3 is a diagram illustrating an example of a plurality of slave nodes transmitting transmission information according to some embodiments of the present disclosure.

Referring to FIG. 3, a master node (100) is installed in a master target facility in which a ground wire (410) is buried, and each of a plurality of slave nodes (200) can be installed in a slave target facility connected to the master target facility through an overhead line (420).

Among the plurality of slave nodes (200), the second slave node (220) can broadcast second transmission information via the first communication protocol. The second slave node (220) can broadcast the second transmission information at a predetermined cycle. The second transmission information can include second measurement data collected by the second slave node (220) and a second node identifier related to the second slave node (220). The first slave node (210) can broadcast the first transmission information via the first communication protocol. The first slave node (210) can broadcast the first transmission information at a predetermined cycle. The first transmission information can include first measurement data collected by the first slave node (210) and a first node identifier related to the first slave node (210). When the first slave node (210) receives the second transmission information according to the broadcast of the second slave node (220), it can broadcast the first transmission information including the second transmission information. According to the broadcast of the first slave node (210), the master node (100) can receive the first transmission information including the first measurement data collected by the first slave node (210) and the first node identifier related to the first slave node (210). Alternatively, according to the broadcast of the first slave node (210), the master node (100) can receive the first transmission information including the second transmission information.

According to one embodiment, the node identifier may include a group identifier associated with group information of a group in which a master node (100) and a plurality of slave nodes (200) are grouped. The plurality of slave nodes (200) may update transmission information if, based on the group identifier, it is determined that a node identifier received from another slave node has been transmitted in a format associated with the group information.

For example, the first slave node (210) may receive second transmission information according to the broadcast of the second slave node (220). The second transmission information may include a second node identifier related to the second slave node. The second node identifier may be composed of a group identifier related to group information and a second identifier indicating the second slave node (220). The first slave node (210) may determine whether the group identifier included in the second node identifier is transmitted in a format associated with group information of the group to which the first slave node (210) belongs. For example, the node identifier of the group to which the first slave node (210) belongs may be composed in a format such as "011_***". "011" may represent a group identifier, and "***" may be an identifier of a slave node that transmitted the transmission information. If the first slave node (210) transmits the first transmission information, the first node identifier included in the first transmission information may be configured as "011_001". In "011_001", "011" may represent a group identifier, and "001" may represent the first identifier of the first slave node (210). The first slave node (210) may determine whether the second node identifier included in the second transmission information is configured in a format such as "011_***". If the first slave node (210) determines that the second node identifier has been transmitted in a format associated with the group information, the first slave node (210) may broadcast the first transmission information including the second transmission information. For example, if the second node identifier has been determined to have been transmitted in a format associated with the group information, such as "011_***", the first slave node (210) may broadcast the first transmission information including the second transmission information. In other words, the first slave node (210) can transmit the second measurement data collected by the second slave node, the second node identifier related to the second slave node (220), the first measurement data collected by the first slave node (210) and the first node identifier related to the first slave node (210) as transmission information to the master node (100).

According to one embodiment, the determination of whether the second node identifier is transmitted in a format associated with group information may be performed by the master node (100).

Specifically, when the first slave node (210) receives the second transmission information according to the broadcast of the second slave node (220), the first transmission information can be generated to include the second transmission information. The master node (100) can receive the first transmission information according to the broadcast of the first slave node (210). The master node (100) can determine whether the second node identifier included in the first transmission information has been transmitted in a format associated with group information. In addition, when the master node (100) determines that the second node identifier has been transmitted in a format associated with group information, the first transmission information including the second transmission information and the report information to be described later can be transmitted to the control server (300).

Meanwhile, if the first slave node (210) determines that the second node identifier was transmitted in a format not associated with group information, the second transmission information may be deleted. For convenience of explanation, reference may be made to FIG. 4. For convenience of explanation, reference may be made to FIG. 5.

FIG. 4 is a diagram illustrating another example of multiple slave nodes transmitting transmission information according to some embodiments of the present disclosure.

Referring to FIG. 4, the first slave node (210) can receive third transmission information from another slave node (510) of another group. Even if a plurality of slave nodes (200) and the master node (100) are grouped according to a pre-designated area, another group of facilities may exist within a range that can be communicated through the first communication protocol depending on the characteristics of the distance at which the target facility must be installed. The first slave node (210) that has received the third transmission information can determine whether the third node identifier included in the third transmission information has been transmitted in a format associated with the group information. Specifically, the first slave node (210) can determine whether the group identifier included in the third node identifier of the third transmission information has been transmitted in a format associated with the group information to which the first slave node (210) belongs. For example, the node identifier of the group to which the first slave node (210) belongs may be configured in a format such as "011_***". "011" may represent a group identifier, and "***" may be an identifier of a slave node that transmitted the transmission information. If the first slave node (210) transmits the first transmission information, the first node identifier included in the first transmission information may be configured as "011_001". The first slave node (210) may determine whether the third node identifier included in the third transmission information is configured in a format such as "011_***". If it is determined that the third node identifier has been transmitted in a format not associated with the group information, the first slave node (210) may delete the third transmission information. For example, if it is determined that the third node identifier has been transmitted in a format not associated with the group information, such as "012_***" or "021_***", the first slave node (210) may delete the third transmission information. Accordingly, transmission information related to other groups may be prevented from being transmitted to the master node (100).

According to one embodiment, the determination of whether the third node identifier has been transmitted in a format associated with group information may be performed by the master node (100).

Specifically, when the first slave node (210) receives third transmission information according to a broadcast of another slave node (510), the first transmission information can be generated to include the third transmission information. The master node (100) can receive the first transmission information according to a broadcast of the first slave node (210). The master node (100) can determine whether the third node identifier included in the first transmission information has been transmitted in a format associated with group information. In addition, when the master node (100) determines that the third node identifier has been transmitted in a format not associated with group information, the first transmission information with the third transmission information deleted and the report information to be described later can be transmitted to the control server (300).

Referring again to FIG. 2, the master node (100) may receive transmission information including measurement data from at least one slave node among a plurality of slave nodes (200) via a first communication protocol (S120). The first communication protocol may be a protocol utilizing a short-range communication network. For example, the first communication protocol may be low-power Bluetooth communication or Bluetooth communication. The transmission information may include measurement data and a node identifier associated with at least one slave node.

For example, the master node (100) may receive first transmission information from a first slave node (210) adjacent to the master node (100) among a plurality of slave nodes (200). According to an embodiment, the first transmission information may include second transmission information received from a second slave node (220) adjacent to the first slave node (210).

For another example, the master node (100) may receive second transmission information from a second slave node (220) adjacent to the master node (100) among a plurality of slave nodes (200). According to an embodiment, the second transmission information may include first transmission information received by the second slave node (220) from a first slave node (210) adjacent to the master node (100).

For another example, the master node (100) may receive first transmission information from a first slave node (210) adjacent to the master node (100) among a plurality of slave nodes (200), and may receive second transmission information from a second slave node (220) adjacent to the master node (100). The first transmission information may include second transmission information, and the second transmission information may include the first transmission information.

The control server (300) can receive report information including transmission information from the master node (100) via a second communication protocol (S130). The second communication protocol may be a protocol utilizing a long-distance communication network. For example, the second communication protocol may be a communication protocol utilizing the Narrowband Internet of Things (NB-IoT).

The report information may include transmission information received by the master node (100) from at least one slave node, measurement data collected by the master node (100), and a node identifier associated with the master node (100). For example, it may be assumed that the at least one slave node is the first slave node (210). In this case, the report information may include the first measurement data collected by the first slave node (210), the first node identifier associated with the first slave node (210), the measurement data collected by the master node (100), and the node identifier associated with the master node (100).

In one embodiment, the report information may include group information that can identify a valid range for the measurement data.

Specifically, the master node (100) and the plurality of slave nodes (200) can share a valid range with respect to measurement data. In other words, the master node (100) and the plurality of slave nodes (200) can be grouped with nodes whose measurement data have the same or similar valid ranges. The master node (100) can transmit group information that can identify the valid range to the control server (300). Accordingly, the control server (300) can identify the valid range with respect to the measurement data of the group to which the master node (100) belongs based on the group information.

Based on the report information, the control server (300) can determine the first node that transmitted measurement data outside the valid range and determine the first target facility where the first node is installed as an abnormal facility (S140).

For example, the control server (300) can determine the first node that shows measurement data that is greater than the valid range or less than the valid range. The first node can be at least one slave node or the master node (100). The control server (300) can determine the first node that transmitted measurement data that is out of the valid range based on the node identifier included in the report information. In addition, the control server (300) can determine the first target facility where the first node is installed as an abnormal facility. Additionally, if it is determined that an abnormal facility exists, the control server (300) can output an alarm or the like to notify the user of the occurrence of the abnormal facility.

According to the above-described configuration, a measurement system (1000) for current and resistance data associated with a target facility can be implemented with a master node (100), a plurality of slave nodes (200), and a control server (300). The plurality of slave nodes (200) can broadcast transmission information via a first communication protocol, and the master node (100) can transmit measurement data collected by the plurality of slave nodes (200) to the control server (300) via a second communication protocol. Accordingly, since only the master node (100) can be implemented to use the second communication protocol that incurs communication costs, the initial cost for implementing the measurement system (1000) and the maintenance cost incurred for maintenance can be reduced.

Meanwhile, according to the above-described configuration, multiple slave nodes (200) can transmit transmission information to each other. Accordingly, if transmission information is not received from at least one slave node, the control server (300) can determine that a problem has occurred in at least one slave node. Furthermore, if report information is not received, the control server (300) can also determine that a problem has occurred in the master node (100). Hereinafter, an example of a method for determining whether an abnormality has occurred in a group to which a master node (100) and multiple slave nodes (200) belong will be described with reference to FIG. 5.

FIG. 5 is a flowchart illustrating an example of a method by which a control server according to some embodiments of the present disclosure determines whether an abnormality has occurred in a group to which a master node and multiple slave nodes belong.

Referring to FIG. 5, the control server (300) can determine whether report information is received at a predetermined cycle. If the report information is received at a predetermined cycle (S210, Yes), the control server (300) can determine whether data has not been collected from a predetermined number or more slave nodes based on the report information.

If the control server (300) determines that data has not been collected from a predetermined number or more of slave nodes (S220, Yes), it can determine that an abnormality has occurred in a group to which the master node (100) and multiple slave nodes (200) belong (S230).

Specifically, the control server (300) may determine that an abnormality has occurred in at least one slave node within a group to which a master node (100) and a plurality of slave nodes (200) belong. In this case, the control server (300) may determine at least one slave node in which an abnormality has occurred based on report information received from the master node (100). For example, the control server (300) may determine a slave node in which a node identifier has not been received as the node in which an abnormality has occurred. According to an embodiment, when a slave node in which an abnormality has occurred is determined, the control server (300) may output an alarm or the like to notify the user of the occurrence of an abnormal group.

If it is not determined that data has not been collected from a predetermined number or more of slave nodes (S220, No), the control server (300) may determine that no abnormality has occurred in the group to which the master node (100) and multiple slave nodes (200) belong. In this case, the control server (300) may wait for report information to be received from the master node (100) according to a predetermined cycle.

Meanwhile, if the report information is not received at a predetermined cycle (S210, No), the control server (300) can determine that an abnormality has occurred in the group to which the master node (100) and multiple slave nodes (200) belong (S230).

Specifically, the control server (300) may determine that an abnormality has occurred in the master node (100) within a group to which the master node (100) and multiple slave nodes (200) belong. In this case, the control server (300) may output an alarm or the like to notify the user that an abnormality has occurred in the master node (100).

The description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present disclosure. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments without departing from the scope of the present disclosure. Therefore, the present disclosure is not intended to be limited to the embodiments disclosed herein, but is to be construed in the broadest scope consistent with the principles and novel features disclosed herein.
