Intelligent lock system of transformer substation relay room and unlocking method

Abstract

The embodiment of the invention provides an intelligent lock system of a transformer substation relay room and an unlocking method. The intelligent lock system comprises an intelligent lock, a serverand a user terminal, wherein the intelligent lock comprises a mechanical lock head, a key hole, a two-dimensional code, a power supply module, a CPU control module, a wireless sending and receiving module and a wireless communication module; the mechanical lock head is in communication connection with the CPU control module; the key hole is used for carrying out telescopic control on the mechanical lock head through a key; the two-dimensional code comprises identification information of the intelligent lock, and an unlocking request is sent to the server through the user terminal when the userterminal scans the two-dimensional code; the power supply module is used for providing a power supply; the CPU control module is used for controlling the telescopic of the mechanical lock head; and the wireless sending and receiving module is used for receiving and sending data through the wireless communication module. The unlocking method is used for opening the intelligent lock. According to the intelligent lock system and the unlocking method, a duty worker in a transformer substation is conveniently responsible for handling the operation site and controlling the operation risk and achieved other basic functions, the practicability, the safety and the convenience are improved, and the safety and the efficiency of production work are improved.

Description

technical field [0001] The invention relates to the technical field of substation equipment information management, in particular to an intelligent lock system and an unlocking method for a relay protection room of a substation. Background technique [0002] At present, most substations are managed in the way of centralized control center inspection and maintenance, and the substations under the inspection and maintenance center adopt the unattended operation and maintenance method. All screen cabinet door locks in unattended substations share a key, and this key is responsible for unlocking all screen cabinet door locks in the whole station. This mode is called "one key pass". The use of the "one key pass" mode is conducive to the on-duty personnel in the substation to control the scope of the working place of the operator, and to a certain extent, it can prevent the operator from opening the screen cabinet door of the non-working place equipment at will, and avoid operatio...

AI Technical Summary

Problems solved by technology

[0003] However, judging from the actual field work feedback, there are many shortcomings in the practicality and convenience of the "one-key communication" protective screen in the substation relay protection room currently used, for example: 1. All the screen cabinets in the entire substation have only one When there are multiple groups of staff working in different places in the same station, it is often necessary to look for the only key to open the door lock of the screen cabinet, which affects the work and increases the risk of the operation; 2. During the work process, the previous work is prone to occur. After the team members finished using the keys, they left them at the original work place or lost them. 3. After some work team members took the "one key pass" key, they directly forgot to return the key and took it away from the substation, making it impossible to open the door lock. Inconvenience caused by on-site work

[0004] It can be seen that the "one-key-communication" mode applied in the substation is likely to affect the on-site work, affect the operation progress, and increase the operation risk
