Description

Technical Field

[0001] The utility model relates to the technical field of electric power communication, and in particular to an operation and maintenance system based on an electric power body area network. Background Art

[0002] The power body area network system is applied to the distribution substation area. It is a star network structure composed of a main aggregation node and terminal sensing nodes. Multiple terminal sensing nodes are directly connected to a main aggregation node to monitor the performance of the equipment and the changes in environmental parameters related to safety. The main node of the body area network equipment completes the information collection of multiple distributed terminal sensing nodes in a wireless interconnected manner. The type, number and working mode of the terminal nodes can be flexibly configured through the main node. Establish a connection between the PC and the main node, and understand the operating status of the sensor by reading the historical messages and real-time data of the data acquisition system on the main node, and complete the corresponding control operations.

[0003] In the power area network system, the main node needs a stable power supply, so the installation position is fixed, which makes it inconvenient to move and is not conducive to problem troubleshooting. In addition, the information collection system matched with the main node focuses on processing information for the user end, so the data reported by the sensing node is not fully analyzed, which is not conducive to the operation and maintenance debugging of the power area network. For example, information such as the signal strength and battery power of the terminal sensing node is not important for environmental monitoring of the distribution station area, but it is a very important reference in fault analysis. At present, there is no dedicated operation and maintenance system for power area network equipment. The existing operation and maintenance system is closer to the user end, focusing on the management of historical records and usage permissions. It is necessary to provide professional wired or wireless interfaces at the computer room level to obtain operation and maintenance data, which is not very useful for underlying fault analysis. If the terminal sensing node fails and causes the loss or abnormal switching of the channel, it is difficult to find and control it through the main node, and the operation based on the main node data requires maintenance personnel to have a high level of professional quality. It is inconvenient to temporarily change the settings during debugging. After debugging, the system needs to be restored to its original state, and the risk of misoperation is greater.

The operation and maintenance system based on the power body area network includes an operation and maintenance module and an operation and maintenance terminal.

The operation and maintenance terminal analyzes the received power equipment operation data and generates an operation and maintenance control instruction according to the analysis results. The operation and maintenance module transmits the operation and maintenance control instructions issued by the operation and maintenance terminal to the convergence node and each sensor node.

[0033] In this embodiment, the operation and maintenance system is used as a body area network module operation and maintenance debugging tool in the Internet of Things system composed of the body area network module. The body area network system is a star network structure composed of aggregation nodes and terminal sensor nodes. Multiple terminal sensor nodes are directly connected to one aggregation node. The hardware part of the operation and maintenance debugging system is based on the body area network module together with the terminal sensor nodes and the aggregation nodes, sharing the drive layer and wireless communication functions. The operation and maintenance module equipped with the operation and maintenance system can communicate with the aggregation node and the terminal sensing node in both directions and complete the corresponding control operations. The operation and maintenance system consists of two parts: hardware and software. The operation and maintenance software runs on a PC or a handheld game console, and is connected to the operation and maintenance module through the PC or the handheld game console. The operation and maintenance module converts the instructions sent by the PC or the handheld game console into wireless interface messages and sends them to each sensor node module.

[0034] In one embodiment, if Figure 2 As shown, the operation and maintenance module includes a wireless communication module and a serial communication module. The wireless communication module includes an antenna and a wireless sensing unit (i.e., a wireless sensing module). The serial communication module includes a data conversion unit (such as a USB converter) and a serial port interface (such as a USB / TYPC interface). The antenna is used to wirelessly communicate with multiple sensor nodes and aggregation nodes, receive the power equipment operation data sent wirelessly by the sensor nodes and the aggregation nodes, and transmit the received power equipment operation data to the wireless sensing unit. The wireless sensing unit presets a sensing program for identifying environmental parameter data related to the equipment safety performance in the power equipment operation data.

[0035] In this embodiment, the operation and maintenance module and the operation and maintenance terminal are installed with corresponding operation and maintenance programs. Since the operation and maintenance module is universal and can have multiple working modes, the wireless sensing unit of the operation and maintenance module is internally configured with corresponding operation and maintenance programs to ensure that the operation and maintenance module can enter the operation and maintenance mode and can perform wireless reception and transmission normally (through the antenna). Complex logical functions are implemented through the operation and maintenance software program installed on the operation and maintenance terminal (PC or handheld device).

[0036] In a specific embodiment, the operation and maintenance process of the operation and maintenance system is as follows: Figure 3 As shown in the figure, the operation and maintenance system has the following functions:

[0037] (1) Monitor and parse all sensor messages: After the operation and maintenance software is started, it receives data within the frequency range based on the set channel, analyzes whether it is a message sent by a sensor, calls the internal sensor model configuration file to parse the message, and displays it by category;

[0038] (2) Operate the sensor: The command is sent in the form of a serial port command. The operation and maintenance system identifies the command as a sensor operation command through the software program and monitors whether the corresponding sensor has sent a control request. After receiving the control request of the corresponding sensor, the corresponding control command is sent. The software program integrates a commonly used command menu for modular operation and provides a transparent transmission mode for manual editing of command content. In addition to sending various configuration commands and transparent transmission messages to the specified sensor, the "operate specified sensor" function can also wirelessly upgrade the sensor firmware;

[0039] (3) Serial port update: Instructions are issued in the form of serial port commands. Serial port updates ensure that the hardware of the operation and maintenance system can adapt to different versions of the software. The wireless sensing module of the hardware can be upgraded and adjusted through the serial port connection;

[0040] (4) Wireless update of aggregation module: The operation and maintenance terminal calls the specified installation file and initiates a serial port command according to the specified communication address. The operation and maintenance module processes the command and converts it into a wireless command through the antenna to perform a wireless upgrade on the corresponding aggregation node module.

[0041] The utility model is a special operation and maintenance system designed for power body area network equipment. It can seamlessly connect to the wireless body area network and achieve deep access to the body area network system. The operation and maintenance operators can perform related debugging operations intuitively and efficiently. The scanning mode of the operation and maintenance system can indiscriminately receive and analyze all data reported by sensors in real time, and it is more convenient to switch channels. Therefore, it has stronger auxiliary analysis capabilities and completes most operations on each node in the wireless body area network without making any changes to the existing system. The utility model provides a special operation and maintenance system for the power body area network. The system does not participate in the normal operation process of the equipment. However, if the operation and maintenance personnel need to check or debug the abnormality of the equipment, accessing the operation and maintenance system can conveniently view and operate the various parameters of the related equipment, greatly improving the operation and maintenance efficiency.
