State Grid Yubei Power realizes remote control of patrol robot
On May 9th, at the spring inspection pre-test site of the 500 kV Jiangjiaying Substation, the maintenance personnel of the State Grid Yubei Power Co., Ltd. successfully applied the electric wireless 4G private network in the control center dozens of kilometers away, and remotely controlled the inspection in the substation. robot. Under the remote control, the inspection robot performs the inspection work in an orderly manner and transmits the detected operation data to the control center in real time. The successful application of the wireless private network to the remote control of the inspection robot solves the technical problem that the inspection robot cannot realize the network control, and significantly improves the work efficiency and the inspection quality.
"The communication between the traditional inspection robot and the control background uses WiFi technology, which can only be operated by manual local control. The inspection data can only be read locally, which brings great inconvenience to the front-line operators and is not efficient. Gao." State Grid Yubei Power Science and Technology Department Li Wei introduced. With the continuous advancement of smart grid construction and the gradual maturity of unlimited private network technology, the company closely tracks the equipment operation and maintenance requirements, actively carries out business needs analysis, network security assessment and technical solution formulation, and proposes a wireless base station sector extension solution. It overcomes six engineering and technical problems such as wireless terminal and robot communication security, power supply, interface matching, address conversion, antenna installation, and robot background control desktop backhaul.
"Under changing the appearance and safety protection performance of the robot, we solved the information security problem of robot remote control and successfully transferred the robot business to the remote control center with 4G wireless private network communication mode to realize remote real-time remote control of the robot. And monitoring, and the real-time HD pictures, thermal imaging images and other information back in real time." State Grid Yubei Power Science and Technology Department Long Hao said. At present, the related technical solutions for remote control of patrol robots have been promoted and applied in a 220 kV substation and four 110 kV substations, significantly improving work efficiency and inspection quality.
In the next step, State Grid Yubei Power will further strengthen professional information communication and work coordination, deepen the application of new information and communication technologies according to the actual needs of production and management, and accelerate the improvement of the networked control level of substation inspection robots. Power wireless private network for the distribution of distribution automation, power distribution maintenance, emergency communications, power information collection, infrastructure live video, etc., to enhance the carrying capacity of power wireless private network for production and management services, maximize the power wireless The comprehensive benefits of the network have accelerated the transformation of production management methods from “decentralized management and control†to “intensive command†and from “manual drive†to “smart driveâ€.
