Step S101: and establishing a wireless private network of the transformer substation. The wireless private network may be established using zigbee technology or 5G technology.
ZigBee is a low power consumption local area network protocol based on IEEE802.15.4 standard. According to international standards, the ZigBee technology is a short-range, low-power consumption wireless communication technology. The name ZigBee, also known as ZigBee protocol, is derived from the dance of bees in the eight characters, because bees (bee) communicate the orientation information of pollen with partners by flying and "dancing" whose wings are shaken by a "zig", i.e. the bees form a communication network in the group in such a way. Therefore, Zigbee is named as a new generation of wireless communication technology. ZigBee has also been referred to as "HomeRF Lite", "RF-easy Link" or "fireFly" heretofore, and is characterized by close range, low complexity, self-organization, low power consumption, low data rate.
The ZigBee is mainly suitable for the fields of automatic control and remote control, and can be embedded into various devices. In short, ZigBee is a low-cost, low-power-consumption short-range wireless networking communication technology. ZigBee is a wireless network protocol for low-speed short-distance transmission. The ZigBee protocol is, from bottom to top, a physical layer (PHY), a media access control layer (MAC), a Transport Layer (TL), a network layer (NWK), an application layer (APL), and the like. Wherein the physical layer and the medium access control layer comply with the provisions of the IEEE802.15.4 standard.
The ZigBee technology is a two-way wireless communication technology with short distance, low complexity, low power consumption, low speed and low cost. The method is mainly used for data transmission among various electronic devices with short distance, low power consumption and low transmission rate and is typically applied to periodic data transmission, intermittent data transmission and low-reaction-time data transmission. Briefly, ZigBee is a highly reliable wireless data transmission network, similar to CDMA and GSM networks. The ZigBee data transmission module is similar to a mobile network base station. The communication distance ranges from standard 75m to hundreds of meters, kilometers, and supports infinite extension.
ZigBee is a wireless data transmission network platform consisting of 65535 wireless data transmission modules, each ZigBee network data transmission module can communicate with each other in the whole network range, and the distance between each network node can be infinitely expanded from 75m of the standard.
Different from a CDMA network or a GSM network of mobile communication, the ZigBee network is mainly established for automatically controlling data transmission in an industrial field, so that the ZigBee network has the characteristics of simplicity, convenience in use, reliability in work and low price. The mobile communication network is mainly established for voice communication, the value of each base station is generally more than million yuan, and the value of each ZigBee base station is less than 1000 yuan.
Each ZigBee network node can be used as a monitoring object, for example, a sensor connected with the ZigBee network node can directly acquire and monitor data, and can automatically transfer data information transmitted by other network nodes. Besides, each ZigBee network node (FFD) can be wirelessly connected with a plurality of isolated sub-nodes (RFDs) which do not take the role of network information transfer within the coverage range of the signal thereof.
In view of the advantages of the ZigBee communication network, the ZigBee communication network can be selected in the substation communication to acquire and process the ground wire information of the substation in real time.
The 5G is known as the fifth generation mobile phone mobile communication standard, also known as the fifth generation mobile communication technology. 5G is also an extension beyond 4G, and the theoretical downlink speed of a 5G network is 10Gb/s (equivalent to a download speed of 1.25GB/s) under study.
The main goal of 5G networks is to keep the end user always in a networked state. The guarantee capability of 5G in the aspect of communication reliability is very important for transformer substation ground wire information acquisition and management and control.
As mentioned above, the ground wire in the substation is the life wire of the protection worker in the field work. At present, in a transformer substation operation and maintenance work site, the assembly and disassembly conditions of a grounding wire of a transformer substation in maintenance are generally recorded in a paper manual recording mode. Due to the working nature of the shift of the substation, the power outage personnel and the power restoration personnel are often not the same personnel. When the construction operation time is too long, once the power outage worker forgets to fill in the ground wire registration record, when the power transmission worker is resumed to return to power transmission, the risk of missed ground wire removal exists. Because the ground wire in the transformer substation has great significance in the aspect of guaranteeing the life safety of workers, even if the transformer substation ground wire real-time acquisition device provided by the embodiment of the application is adopted to replace the existing working mode of recording ground wire information by paper, the communication risk and doubt still exist. The digitized ground information needs to be transmitted over a reliable and stable communication network. The 5G network has outstanding performance in the aspects of communication speed and communication reliability, and particularly the 5G communication reliability is excellent, so that the 5G communication network is very suitable for being applied to the transformer substation ground wire real-time acquisition device provided by the embodiment of the application.

And an acquisition module is arranged on the ground wire fixed by each group of ground wire heads and the equipment framework, and the module can acquire the position and the number of the ground wire and transmit acquired information to the master station through a wireless private network.
Step S103: a main station real-time display system is established, and a primary wiring simulation diagram in the main station can display the position and the number of the ground wire in real time, prompt the time and personnel for installing the ground wire and play a role in visual inspection.
Step S104: the five-prevention interlocking function is realized. The real-time ground wire acquisition system and the five-prevention management system are interlocked through encryption and technical isolation means, namely, when the ground wires are not dismounted in the interval, the operation of the interval disconnecting link and the breaker cannot be carried out. Once someone forcibly operates the mobile phone, the mobile phone can realize the alarm function and send the information of the operator to the mobile phone of the manager through the short message.
Step S105: the automatic registration function is realized. Through the transformer substation ground wire real-time acquisition device provided by the embodiment of the application, the time, the interval position, the ground wire number and the operator information when the worker installs and removes the ground wire can be automatically registered to generate the related electronic record, and paperless office is realized.
