System and method for telephone permit work ticket management and control

Abstract

A telephone license operation order management and control system is characterized by comprising an operation and maintenance center server, an intelligent lock control host, a computer key, and transformer station access control locksets. The operation and maintenance center server is in communication connection with intelligent lock control host via wireless network; the computer key matches with the intelligent lock control host; the computer key conducts wireless communication with the intelligent lock control host through the communication module; unlock permission of each access control and corresponding RFID coding of an RFID chip in the lock are stored in the intelligent lock control host; and the computer key reads the RFID coding in the transformer station access control mechanical lockset, and opens the lockset in each transformer station access. The system can effectively solve the problem of incapability of telephone license operation order management and control in the previous work; after using the system, the process of remote licensing and operation order termination by maintenance personnel is standardized, and the action area of maintenance personnel in the work process is strictly controlled, so as to lay a good foundation for safe power production.

Description

technical field The invention belongs to the technical field of remote management and control, and in particular relates to a system and method for controlling and controlling telephone permit work tickets in a power system. Background technique A work ticket is a written order to allow work on electrical equipment. It is also a written basis for clarifying safety responsibilities, making safety disclosures to staff, performing work permit procedures, work interruption, transfer and termination procedures, and implementing technical measures to ensure safety. Therefore, when working on electrical equipment, it is very necessary to fill in the work tickets carefully as required. Traditional and paper-based work tickets are filled out by hand, which is likely to cause problems such as illegible handwriting, typos, and unclear content expressions, and there are certain potential safety hazards. The work ticket is a written certificate that must be held by every person entering...

AI Technical Summary

Problems solved by technology

Taking the conventional 220 kV substation as an example, there are more than 500 mechanical lock points in the station, and there are more than 20-30 kinds of keys. Due to the large number of locks and inconsistent keys, the operation and maintenance personnel have to do daily inspections and switching operations. It takes a lot of time to manage and search for keys, which greatly reduces the efficiency of daily operation and maintenance
