Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
According to the embodiment of the invention, a method for monitoring a power supply by a network management system is provided. Fig. 1 is a flowchart of a method for monitoring a power supply in a network management system according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S102, the network management system obtains the state information of the power supply, wherein the state information is the warning information of the power supply or the energy information of the power supply;
and step S104, the network management system controls the power supply network element of the power supply to perform power saving processing according to the acquired state information.
Through the steps, the network management system controls the network element to perform power saving processing according to the acquired state information of the power supply, so that the problem that the power supply is possibly exhausted in a short time when the alternating current is interrupted in the related technology is solved, the service time of the power supply is prolonged, and the effects of saving energy and reducing consumption are achieved.
Preferably, before step S102, an Environmental Power Management (EPM) device may send a command for inquiring the status information to the Power supply; the EPM device receives and saves state information from the power supply; and under the condition that the state information is the alarm information, the EPM equipment prompts the alarm information to the user and reports the alarm information to the network management system. For example, when receiving energy information of a power supply, the EPM device only stores the energy information in a local network for query by a network management system; when receiving the alarm information of the power supply, the system not only stores the alarm information, but also immediately reports the alarm information to the network management system. The method improves the effectiveness of the system.
Preferably, in the case that the status information is energy information, in step S102, the network management system may send a command for querying the energy information to the EPM device, where the energy information is voltage and/or current of the power supply; and the network management system receives the energy information returned by the EPM equipment. By the method, the network management system can know the service condition of the power supply during the AC power failure, so that corresponding treatment can be carried out in time, and the performance of the system is improved.
Preferably, in step S104, the network management system may determine whether the current battery capacity of the power supply is lower than a preset threshold according to the acquired energy information; if the value is lower than the preset threshold value, the network management system remotely closes the network element. The method can avoid emptying the battery and prolong the service life of the battery.
Preferably, in the case that the status information is the alarm information, in step S104, the network management system may determine the alarm type according to the acquired alarm information; and the network management system controls the network element to perform corresponding power saving processing according to the determined alarm type. The method is simple and practical and has strong operability.
Preferably, the step of controlling, by the network management system, the network element to perform the corresponding power saving processing according to the determined alarm type may include: when the alarm type is an alternating current power failure alarm, the network management system informs the network element to start a power saving mode (for example, the network management system sets a narrowband user port which is not numbered to be in a high-resistance state and periodically enables and disables a broadband user port or reduces the fan speed of the network element in the power saving mode); when the alarm type is a power-off alarm, the network management system sends a command for indicating to close the broadband function to the network element; and when the alarm type is a secondary power-off alarm, the network management system remotely closes the network element. The method can save the power consumption of the network element, thereby prolonging the service time of the power supply energy.
Preferably, the network element is an integrated media Access gateway (MSAG).
According to the embodiment of the invention, the invention also provides a network management system. Fig. 2 is a block diagram of a network management system according to an embodiment of the present invention, and as shown in fig. 2, the network management system 20 includes: the acquiring device 22 is used for acquiring the state information of the power supply, wherein the state information is the warning information of the power supply or the energy information of the power supply; and the power saving device 24 is coupled to the obtaining device 22 and is used for controlling the power supply network element of the power supply to perform power saving processing according to the obtained state information.
Through the network management system 20, the power saving processing mode is performed by controlling the network element according to the acquired state information of the power supply, so that the problem that the power supply is likely to be exhausted in a short time when the alternating current power fails in the related art is solved, the service time of the power supply is prolonged, and the effects of energy conservation and consumption reduction are achieved.
Fig. 3 is a block diagram of a network management system according to a preferred embodiment of the present invention, and as shown in fig. 3, the network management system 20 further includes: sending means 26 for sending a command for querying energy information to the environmental dynamics monitoring EPM device, wherein the energy information is a voltage and/or a current of the power supply; and a receiving device 28, coupled to the obtaining device 22, configured to receive the energy information returned by the EPM device and the alarm information reported by the EPM device.
Preferably, the power saving device 24 includes: a determining module 242, configured to determine whether the current battery capacity of the power supply is lower than a preset threshold according to the energy information acquired by the acquiring device 22; a shutdown module 244, configured to remotely shutdown the network element when the current battery capacity of the power supply is lower than a preset threshold; or, the determining module 246 is configured to determine the alarm type according to the alarm information acquired by the acquiring device 22; and a control module 248, configured to control the network element to perform corresponding power saving processing according to the alarm type determined by the determining unit.
The implementation of the above embodiments will be described in detail below with reference to the preferred embodiments and the accompanying drawings.
Example one
The embodiment provides a power saving method applied to MSAG equipment, wherein EPM equipment is adopted to monitor an intelligent power supply for supplying power to the MSAG equipment, the EPM equipment reports power supply alarms at any time, after a network management system receives related alarms reported by the EPM equipment, on one hand, related personnel are informed to process faults in time, on the other hand, a control command is sent to a network element (namely, a power supply network element of the intelligent power supply) to close some unimportant functions, so that the purpose of saving power is achieved, the effects of saving energy and reducing consumption are achieved, and the service time of the network element system can be prolonged as much as possible under the condition of mains supply power failure. In addition, the user can also look over the analog quantity such as voltage, electric current of intelligent power supply from the EPM equipment through the inquiry command at any time on the remote network management equipment to confirm the surplus of intelligent power supply, when the intelligent power supply is about to empty, long-range closing network element, and then make the network element stop the power consumptive to intelligent power supply, avoid intelligent power supply to empty air, can't recharge.
Fig. 4 is a schematic diagram of a network management system according to an embodiment of the present invention, and as shown in fig. 4, a method for monitoring a power supply by the network management system may include the following steps:
Step 2, the network manager sends an analog quantity query command to the EPM through the network element, and the EPM returns analog quantity information; meanwhile, the EPM reports the alarm and the alarm is recovered at any time. It should be noted that although the data flow herein needs to be transmitted through the network element, the network element actually only performs transparent transmission processing on the communication information before the network manager and the EPM, and does not perform analysis. The method has the advantages that the dependence between the EPM and the network element does not exist, and the expansibility of the system can be enhanced.
And 3, when the network manager obtains some special alarms reported by the EPM or checks that the capacity of the power supply battery (obtained through analog quantities such as voltage, current and the like of the intelligent power supply) is at a lower level, controlling the network element to perform corresponding power saving treatment.
In the specific implementation process, the EPM can continuously and circularly send query commands to the monitored intelligent power supply, wherein a part of the commands obtain real-time analog quantity information of the intelligent power supply, such as voltage, current and the like, the EPM temporarily stores the analog quantity information, and replies when the network management system issues the query commands; the other part of the commands obtains the alarm state of the intelligent power supply, when a new alarm appears, the EPM immediately reports the alarm state to the network management and temporarily stores the current alarm; when the current temporary alarm disappears, the EPM immediately reports the alarm recovery message to the network manager.
Therefore, the network management system in the embodiment can actively perform management power-saving processing on the network element under the condition of exchange power failure of the MSAG equipment, so that the service time of the network element is prolonged as much as possible.
Example two
The network management system in this embodiment can perform power saving processing according to the alarm information reported by the EPM device. For example, the alarm information may be classified into the following three types: the system comprises an alternating current power failure alarm, a primary power-off alarm and a secondary power-off alarm. The network management system may perform corresponding node processing for different alarm types, specifically, the node processing may be:
when EPM reports AC power failure alarm, network management system reports network element automatically to start power saving mode, but this stage still ensures normal operation of all services. The power saving operation performed by the network element comprises: the method comprises the steps of setting a narrowband user port which is not numbered to be in a high impedance state, automatically reducing feed current when a busy tone of a user is detected and the narrowband user port enters a lockout state, reducing power consumption by enabling and disabling operations of the wideband user port periodically, reducing power consumption by sacrificing certain link establishment time, reducing the speed of a matched fan of MSAG equipment and the like.
And secondly, when the EPM reports a power-off alarm, the operation of the battery DC power supply for a period of time after the AC power failure is shown, and the recovery is still not realized. After receiving a power-off alarm, the network management system sends a command to the network element to close the broadband function and only reserve the narrowband function. Therefore, the time for the network element to provide the voice service can be prolonged as far as possible under the condition of sacrificing the broadband function.
And thirdly, when the EPM reports the secondary power-off alarm, the residual capacity of the battery for supplying power to the MSAG equipment is very low, and only a short time can be supported. After receiving the alarm of secondary power-off, the network management system remotely closes the network element to avoid emptying the battery.
Because the communication protocols of the intelligent power supply are various, and not all the power supplies support reporting of all three alarms, the EPM provides a supplementary processing mode, namely, active management is carried out according to the inquired battery capacity, and the specific mode for managing the network element is the same as the method. Preferably, the ac power supply part of some small devices may not use the intelligent power supply, but the power supply battery may be directly monitored by the EPM module of the network element, and other processing manners are similar.
It should be noted that, although the embodiment of the present invention is based on the MSAG device in the fixed network access network, since there is no dependency between the EPM device and the network element, the scheme for monitoring the power supply by the network management system in the embodiment of the present invention is not limited to the fixed network access network, and may be extended to other communication systems.
In summary, the network management system in this embodiment can perform reverse control (i.e., perform power saving processing on the network element) according to the power monitoring result, thereby playing a role in saving energy and reducing consumption, and prolonging the service time of the power supply.
It will be apparent to those skilled in the art that the modules or steps of the present invention described above may be implemented by a general purpose computing device, they may be centralized on a single computing device or distributed across a network of multiple computing devices, and alternatively, they may be implemented by program code executable by a computing device, such that they may be stored in a storage device and executed by a computing device, or they may be separately fabricated into various integrated circuit modules, or multiple modules or steps thereof may be fabricated into a single integrated circuit module. Thus, the present invention is not limited to any specific combination of hardware and software.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
