Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present invention and should not be construed as limiting the present invention.

The power communication network can provide an efficient, convenient and reliable communication form and communication technology for the power system, and is the basis for safe and stable operation of the power system. In the power communication network, the power distribution communication network is an important component of the power communication network, and flexible access of different service requirements of a power distribution network is supported mainly by utilizing an advanced, mature, economic and reasonable communication technology. The low-voltage distribution area is a typical application scene of a power distribution network communication technology, a communication network of the low-voltage distribution area undertakes access of electric power user electric meters, various intelligent switches, terminal equipment, distributed photovoltaic new energy and other equipment in the area, and multiple functions of data acquisition, state monitoring and the like of the equipment, and different service quality requirements of wide coverage, low time delay, high reliability and the like need to be met.

The communication network of the low-voltage distribution area has the characteristics of complex application environment, various service bearing requirements, multiple measurement monitoring points, high transmission reliability requirement and high possibility of being influenced by power grid expansion and external factors, so that the operation and maintenance workload of the low-voltage distribution area is large. In the related art, remote monitoring, intelligent monitoring and intelligent operation and maintenance management of a low-voltage distribution substation area are generally realized through an intelligent operation and maintenance monitoring system. The system relies on big data of the electric power thing networking, configures main terminal equipment at distribution transformer side, configures slave terminal equipment at branch box and ammeter case, and based on the topological relation in platform district, the communication network of utilizing the low pressure to distribute the distribution platform district realizes that the data of joining in marriage transformer, branch box, ammeter case transmit step by step, in time perception distribution network equipment state. The system can also know the impedance change of a terminal power supply line by analyzing the current and voltage change conditions of the branch box and the ammeter box, judge whether the line has the problems of aging, grounding and the like, monitor the state of the low-voltage line on line and provide support for active operation and maintenance troubleshooting of a low-voltage power grid. However, with the continuous development of the smart power grid, the requirements of more diversified acquisition objects, more flexible acquisition communication modes, more efficient data analysis and wider data application are provided for the intelligent operation and maintenance monitoring system of the low-voltage distribution substation, and the integrity and the real-time performance of the whole communication network are very important.

In the related art, power distribution monitoring and utilization services of a low-voltage power distribution station are generally realized by a concentrator. The concentrator is connected with the acquisition equipment for communication based on a single power line carrier communication technology or a single micropower wireless communication technology in a downlink mode, and is connected with the power system master station for communication in an uplink mode through an optical fiber or a wireless public network or a wireless private network in a single mode, and the communication mode is single. In some cases, the communication full coverage of the equipment on the side of the distribution room cannot be realized, and the requirements on the reliability and timeliness of the intelligent operation and maintenance monitoring system of the low-voltage distribution room cannot be met.

In order to effectively improve the reliability and timeliness of the intelligent operation and maintenance monitoring system of the low-voltage distribution transformer area, it is necessary to provide a transformer area monitoring system, an operation and maintenance terminal, a monitoring module and a transformer area monitoring method, and a plurality of communication channels can be constructed between the operation and maintenance terminal and the monitoring module for data interaction. When the low-voltage distribution transformer area needs to be remotely operated and maintained, the operation and maintenance terminal remotely starts the monitoring function of the monitoring module by issuing an instruction, data monitoring is carried out on a plurality of measuring points, and the monitoring module can send monitoring data to the operation and maintenance terminal through a plurality of communication channels so as to improve the communication rate and the communication success rate of the transformer area monitoring system. The transformer area monitoring system and the transformer area monitoring method can also realize remote monitoring and operation and maintenance of the monitored transformer area through various working modes such as simulating a transformer area concentrator, real-time state monitoring, offline state monitoring and the like. Through setting up different fortune dimension control mode, can satisfy the multiple user demand that carries out remote monitoring to low pressure platform district to reduce the on-the-spot maintenance work load, reduce the personnel of problem analysis and treatment and the input cost of time.

Fig. 1a is a scene schematic diagram of an application of a distribution room monitoring system, an operation and maintenance terminal, a monitoring module, and a distribution room monitoring method provided in this specification. Taking a low-voltage distribution area including a concentrator, a central coordinator CCO, a proxy coordinator PCO and end devices STA as an example, the concentrator is connected with the central coordinator CCO through a local communication mode of the area, the central coordinator CCO is connected with a primary proxy coordinator PCO1 through a local communication mode, the primary proxy coordinator PCO1 is connected with a secondary proxy coordinator PCO2 and a plurality of end devices STA through a local communication mode, so that the concentrator can collect data used and collected in the area through a local communication network formed by connection of devices in the area. The concentrator is also in communication connection with a remote power consumption information acquisition main station platform through a 4G/5G communication network so as to send the collected power consumption data to the power consumption information acquisition main station platform.

In this scenario example, a corresponding monitoring module is deployed at each end device STA, and an operation and maintenance terminal OMT is deployed at a central coordinator CCO. Each monitoring module MM is correspondingly connected with each terminal equipment STA one by one in a serial port line connection mode so as to monitor the running state of each terminal equipment STA and generate corresponding monitoring data. And the operation and maintenance terminal OMT is connected with the central coordinator CCO in a local communication mode or a serial port line connection mode so as to monitor the running state of the central coordinator CCO and generate corresponding monitoring data. And special wireless communication networks are established among the monitoring modules MM and between the monitoring modules MM and the operation and maintenance terminal OMT for data interaction, so that the monitoring modules MM can transmit the monitoring data to the operation and maintenance terminal OMT through the special wireless communication networks. Each monitoring module MM is also connected with a proxy coordinator PCO corresponding to each terminal device STA in a local communication mode, so that each monitoring module MM can transmit monitoring data to the operation and maintenance terminal OMT by means of a local communication network between each device in the platform area. The operation and maintenance terminal OMT is in communication connection with a remote platform area monitoring platform through a 4G/5G communication network so as to send monitoring data of a monitored platform area to the platform area monitoring platform for storage and filing, and the platform area monitoring platform transmits the monitoring data to the electricity consumption information acquisition main station platform through data security transmission mechanisms such as internal and external network firewall and the like so as to provide data support for later-stage fault analysis and check.

The embodiment of the specification provides a station area monitoring system, and the station area is provided with a central coordinator CCO and an end device STA. Referring to fig. 1b, the station monitoring system 100 may include: the operation and maintenance terminal 110 connected to the central coordinator CCO, and the monitoring module 120 connected to the end device STA.

An operation and maintenance terminal 110 having a first power line communication module 112 and a first near field communication module 114; and the monitoring module 120 is provided with a second power line communication module 122 and a second short-range communication module 124, and is configured to monitor an operating state of the end device STA to generate monitoring data, and transmit the monitoring data to the operation and maintenance terminal through a power line transmission channel corresponding to the unavailable partial short-range wireless channel and an available short-range wireless channel when the partial short-range wireless channel is unavailable. Wherein the power line transmission channel is established between the first power line communication module 112 and the second power line communication module 122; a short-range wireless channel is established between the first short-range communication module 114 and the second short-range communication module 124.

The operation and maintenance terminal can be a terminal device or a module connected with the central coordinator in a power line carrier communication mode or a serial line communication mode and is responsible for carrying out remote data communication with the monitoring module. The monitoring module can be a module which is correspondingly connected with each terminal device one by one in a power line carrier communication mode or a serial port line communication mode and is responsible for monitoring the running state of each terminal device and sending the monitoring data to the operation and maintenance terminal. Specifically, the monitoring module may monitor and collect state information such as data interaction content, interaction delay, data integrity, and the like between each terminal device and other devices in the distribution room in the operation process of the corresponding connected terminal device, and a fault handling log of each terminal device, so as to generate monitoring data for each terminal device, and may send the monitoring data to the operation and maintenance terminal.

In some embodiments, the operation and maintenance terminal may be used to monitor the operating status of the central coordinator. In some cases, the monitoring data of the monitoring module needs to be checked to analyze the accuracy, timeliness and the like of the monitoring data obtained by monitoring the terminal equipment in the monitored transformer area. Therefore, the operation and maintenance terminal can be used for monitoring the operation state of the central coordinator and generating the monitoring data aiming at the central coordinator, so that the operation and maintenance personnel can use the monitoring data aiming at the central coordinator for checking the monitoring data aiming at the monitoring module so as to analyze the monitoring efficiency of the monitored transformer area and the like.

The power line communication module may be a functional module that performs data interaction in a power line carrier communication manner. The near field communication module may be a functional module that performs data interaction through a near field wireless communication method, and specifically, the wireless communication method may include one or more hybrid communication methods among a HRF (high Radio Frequency) communication method, a Long Range Radio (Long Range Radio) communication method, a Bluetooth Mesh (Bluetooth Mesh) communication method, a wireless local area network (wlan) communication method, a ZigBee communication method, an Ultra Wide Band (UWB) communication method, and a microwave communication method.

A power line transmission channel is established between the operation and maintenance terminal and the monitoring module through respective power line communication modules, so that data interaction can be carried out between the operation and maintenance terminal and the monitoring module in a power line carrier communication mode. Specifically, the power line transmission channel between the operation and maintenance terminal and each monitoring module may be established through a power line communication path between a central coordinator of the station area, an end device, and the like. Illustratively, an HPLC carrier communication channel is established between the central coordinator, the end devices, and other devices in the station area for data transmission, and then the power line communication modules of the operation and maintenance terminal and each monitoring module may include an HPLC carrier communication module. Each monitoring module can send the monitoring data to the operation and maintenance terminal through the power line communication module by utilizing an HPLC carrier communication mode through an HPLC carrier communication channel in the transformer area.

A close-range wireless channel is further established between the operation and maintenance terminal and the monitoring module through respective close-range communication modules, so that data interaction can be carried out between the operation and maintenance terminal and the monitoring module in a wireless communication mode. Specifically, a dedicated data transmission channel is established between the near field communication module of the operation and maintenance terminal and the near field communication module of each monitoring module through a wireless communication network, so that each monitoring module can directly send monitoring data to the operation and maintenance terminal through the data transmission channel.

Specifically, for data transmission between the operation and maintenance terminal and each monitoring module, a technical scheme that a short-distance wireless channel is preferred and a power line transmission channel is auxiliary is adopted, and the short-distance wireless channel is preferably selected for data interaction. In some cases, when data interaction is directly performed between the operation and maintenance terminal and the monitoring module through a power line transmission channel, a channel of a power line communication path between each device in the distribution room needs to be occupied, so that collection of information such as power consumption in a normal distribution room is possibly affected, and communication rate and quality are reduced. In other cases, when data interaction is directly performed between the operation and maintenance terminal and the monitoring module through the short-distance wireless channel, wireless signal transmission may be affected by factors such as distance, shielding objects, network faults and the like, so that signal quality is poor, and integrity and timeliness of data transmission cannot be guaranteed. Therefore, the technical scheme that the short-distance wireless channel is preferred and the power line transmission channel is used as an auxiliary channel can be adopted, so that the influence on the collection of information such as power utilization and the like in a normal distribution area caused by the use of the power line transmission channel is reduced as much as possible, and the reliability of communication between the operation and maintenance terminal and the monitoring module is ensured.

Illustratively, each monitoring module may send monitoring data to the operation and maintenance terminal through the short-distance wireless channel and the power line transmission channel, and calculate, in real time, a signal-to-noise ratio, a data reception success rate, a signal delay, a signal loss, and the like under the short-distance wireless channel corresponding to each monitoring module according to communication conditions such as sending and receiving of the data, respectively, to perform real-time analysis on the communication quality of the short-distance wireless channel corresponding to each monitoring module, so as to determine whether each monitoring module can send the monitoring data to the operation and maintenance terminal with high quality through the respective corresponding short-distance wireless channel. If the communication quality of the short-distance wireless channel between the monitoring module and the operation and maintenance terminal is better according to calculation and analysis by the monitoring module, the monitoring module directly uses the corresponding short-distance wireless channel to send monitoring data to the operation and maintenance terminal; if the communication quality of the short-distance wireless channel between the monitoring module and the operation and maintenance terminal is poor according to calculation and analysis by the monitoring module, the monitoring module sends monitoring data to the operation and maintenance terminal by using the corresponding power line transmission channel, so that each monitoring module can stably send the monitoring data to the operation and maintenance terminal, and the integrity and timeliness of the data are ensured.

In some embodiments, the operation and maintenance terminal may send data such as a monitoring instruction to the operation and maintenance terminal through the short-distance wireless channel and the power line transmission channel in the same manner, and calculate a signal-to-noise ratio, a data receiving success rate, a signal delay, a signal loss, and the like in the short-distance wireless channel between the operation and maintenance terminal and each monitoring module according to communication conditions such as sending and receiving of the data, so as to analyze, in real time, communication quality of each short-distance wireless channel where the operation and maintenance terminal is located, so as to determine whether the operation and maintenance terminal can perform data interaction with the operation and maintenance terminal through each short-distance wireless channel.

In the embodiment, communication resources are optimized and integrated, a reliable platform area monitoring operation and maintenance communication network is constructed between the operation and maintenance terminal and the monitoring module through the short-distance wireless communication with priority and the power line communication as an auxiliary communication mode, so that the monitored platform area is monitored, debugged, troubleshooting and the like, meanwhile, various communication channels can be intelligently selected, the reliability of the platform area operation and maintenance communication is greatly improved, and the reliability and timeliness of the monitoring system are improved.

In some embodiments, referring to fig. 2, the operation and maintenance terminal 110 further has a remote communication module 210, configured to send the monitoring data to the platform area monitoring platform 220 through the remote communication module 210.

The remote communication module can be a functional module for data interaction in a remote wireless communication mode. Specifically, the remote wireless communication method may include one or more hybrid communication methods among communication methods such as GPRS (General Packet Radio Service) communication, CDMA (Code Division Multiple Access) communication, and 4G/5G communication. The platform area monitoring platform can be a remote operation and maintenance main station platform, can store, file, analyze in real time and the like received monitoring data, and can also position the fault position of the monitored platform area according to the received monitoring data.

Specifically, the operation and maintenance terminal can upload the monitoring data for the central coordinator of the transformer area and the received monitoring data for each terminal device of the transformer area to a remote transformer area monitoring platform through the remote communication module, and save and file the monitoring data, so as to reduce the workload of maintaining and troubleshooting the transformer area on site, provide data support for later-stage fault analysis and monitoring data check, and reduce the investment cost of problem analysis and processing.

In some embodiments, referring to fig. 3, the operation and maintenance terminal 110 further includes a first processing module 310, a first power management module 320, and a first power input interface module 330. The first processing module 310 is connected to the first power line communication module 112, the first short-range communication module 114, the long-range communication module 210, and the first power management module 320, respectively; the first power management module 320 is connected to the first power input interface module 330.

The first processing module is used for representing a processing module with functions of data processing, data sending, data receiving, data caching and the like. Specifically, the first processing module may be an MCU processing module.

The first power management module can be used for providing corresponding working power for the functional module connected with the first power management module. The first power input interface module may be configured to input power to the first power management module.

Specifically, the first processing module and the first power line communication module may be connected by a serial line, and the first power line communication module may also be connected by a serial line with the central coordinator, so that the first processing module may perform data interaction with the central coordinator in a power line communication manner. For example, the first processing module may send, through the first power line communication module, an instruction instructing the monitoring module to start monitoring to the central coordinator, and transmit the instruction to the monitoring module through the central coordinator in the platform area and a power line communication path connected thereto, so as to instruct the monitoring module to monitor the end device and generate monitoring data. The first processing module can also receive monitoring data transmitted by the monitoring module through the central coordinator and the power line communication path connected with the central coordinator through the first power line communication module. The monitoring data received by the first processing module can be stored in a buffer corresponding to the first processing module.

The first processing module can be connected with the first near field communication module through a serial port line, and the first near field communication module can also be connected with the monitoring module through a near field wireless communication network, so that the first processing module can preferentially utilize a near field wireless communication mode to perform data interaction with the monitoring module corresponding to the available near field wireless channel under the condition that the near field wireless channel where the first near field communication module is located is available. For example, the first processing module may send, through the first near-field communication module, an instruction instructing the monitoring module to start monitoring to the monitoring module, so as to instruct the monitoring module to monitor the end device and generate monitoring data. The first processing module can also receive the monitoring data sent by the monitoring module through the first near field communication module. The monitoring data received by the first processing module can be stored in a buffer corresponding to the first processing module.

The first processing module and the remote communication module can be connected through serial port lines, and the remote communication module can also be connected with the platform area monitoring platform through a remote wireless communication network, so that the first processing module can perform data interaction with the platform area monitoring platform in a remote wireless communication mode. Illustratively, the first processing module may receive, through the remote communication module, an instruction that instructs the operation and maintenance terminal and the monitoring module to start monitoring, which is sent by the platform area monitoring platform, and monitor the central coordinator and generate monitoring data according to the start instruction. The monitoring data generated by the first processing module may be stored in a buffer. The first processing module can also send the monitoring data aiming at the central coordinator of the transformer area and the received monitoring data aiming at each terminal device of the transformer area to the transformer area monitoring platform in a remote wireless communication mode. In some embodiments, the first processing module may upload the monitoring data for the central coordinator and the received monitoring data for each end device stored in the buffer to the platform area monitoring platform in a mode of periodic automatic transmission or manual transmission by a field operation and maintenance person.

For example, the second processing module may receive, through the power line communication module, an instruction that instructs the monitoring module to which the second processing module belongs to start monitoring and is transmitted by the operation and maintenance terminal through the end device and the power line communication path connected to the end device, and monitor the end device and generate monitoring data according to the start instruction.

The second processing module can also transmit the monitoring data aiming at the end equipment to the operation and maintenance terminal by utilizing a near field communication mode.

In some embodiments, the monitoring module is further configured to enable all of the power line transmission channels to transmit the monitoring data to the operation and maintenance terminal if all of the short-range wireless channels are unavailable.

The situation that the short-distance wireless channel is unavailable can indicate that wireless signals transmitted through the short-distance wireless channel are influenced by factors such as shelters and network faults, or the wireless communication distance between the monitoring module and the operation and maintenance terminal is long, so that the communication quality of the short-distance wireless channel is poor, and the integrity and timeliness of data transmitted through the short-distance wireless channel cannot be guaranteed.

Illustratively, each monitoring module may send monitoring data to the operation and maintenance terminal through the short-range wireless channel and the power line transmission channel, and calculate, in real time, a signal-to-noise ratio, a data reception success rate, a signal delay, a signal loss, and the like in the short-range wireless channel corresponding to each monitoring module according to communication conditions such as sending and receiving of the data, respectively, to perform real-time analysis on communication quality of the short-range wireless channel corresponding to each monitoring module, so as to determine whether each monitoring module can directly send the monitoring data to the operation and maintenance terminal through the respective corresponding short-range wireless channel. And if the communication quality of the short-distance wireless channel between each monitoring module and the operation and maintenance terminal is poor according to calculation and analysis, each monitoring module sends monitoring data to the operation and maintenance terminal by using the corresponding power line transmission channel.

In some embodiments, the monitoring module is further configured to send the monitoring data to the operation and maintenance terminal through all the short-range wireless channels if all the short-range wireless channels are available.

It should be noted that, for the description that the monitoring module sends the monitoring data to the operation and maintenance terminal through all the short-distance wireless channels in the foregoing embodiment, please refer to the description in this specification that the monitoring module starts all the power line transmission channels to send the monitoring data to the operation and maintenance terminal, and details are not repeated here.

In some embodiments, the number of monitoring modules is greater than or equal to 2; the monitoring module comprises a relay monitoring module and other monitoring modules, and the distance between the relay monitoring module and the central coordinator is smaller than the distance between the other monitoring modules and the central coordinator.

The relay monitoring module is used for receiving the monitoring data sent by other monitoring modules and sending the monitoring data of the relay monitoring module and the monitoring data sent by other monitoring modules to the operation and maintenance terminal.

The relay monitoring module may be configured to increase a maximum transmission distance for transmitting data between the monitoring module and the operation and maintenance terminal. The distance between the relay monitoring module and the central coordinator may represent a communication distance between the relay monitoring module and the central coordinator.

It should be noted that, because the operation and maintenance terminal is connected to the central coordinator, the distance between the relay monitoring module and the central coordinator is smaller than the distances between the other monitoring modules and the central coordinator, and it can also be understood that the distance between the relay monitoring module and the operation and maintenance terminal is smaller than the distances between the other monitoring modules and the operation and maintenance terminal.

In some cases, due to the influence of loss, transmission distance, signal frequency and other factors, the power of the signal transmitted on the communication channel gradually attenuates, and the attenuation causes signal distortion to a certain extent, thereby causing data reception errors. Therefore, the relay monitoring module receives the monitoring data sent by other monitoring modules and sends the monitoring data to the operation and maintenance terminal, so that the reliability of data transmission in the monitoring system can be further ensured, and the maximum transmission distance of data interaction between other monitoring modules and the operation and maintenance terminal can be increased. In other cases, due to the large number of monitoring modules, the data transmitted over the communication channel may be limited by the capacity of the communication channel, thereby resulting in a reduced rate of data transmission. Therefore, the relay monitoring module receives the monitoring data sent by other monitoring modules, the pressure of data transmission between the relay monitoring module and the operation and maintenance terminal can be reduced, and the efficiency of data transmission is improved.

Specifically, the relay monitoring module in the monitoring modules may be determined according to the quality of the signal sent by the monitoring module to the operation and maintenance terminal. For example, the operation and maintenance terminal may issue an instruction for data transmission channel connection to each monitoring module, and after each monitoring module receives the instruction and confirms a communication channel that may be used for data interaction with the operation and maintenance terminal, may send corresponding confirmation information to the operation and maintenance terminal. And the operation and maintenance terminal receives the confirmation information sent by each monitoring module and can determine the relay monitoring module according to the signal strength or the attenuation degree of the signal sent by each monitoring module.

The relay monitoring module can receive the monitoring data sent by other monitoring modules. Specifically, a short-distance wireless channel between the monitoring modules can be established between the monitoring modules through the second short-distance communication module, so that data interaction can be performed between the monitoring modules through a short-distance wireless communication mode. After receiving the monitoring data sent by other monitoring modules, the relay monitoring module can send the own monitoring data and the monitoring data sent by other monitoring modules to the operation and maintenance terminal through the confirmed communication channel which can be used for data interaction with the operation and maintenance terminal.
