Equipment operation authority control method and device, computer key and server

Abstract

The invention provides an equipment operation authority control method and device, a computer key and a server, and relates to the technical field of equipment control, and the method comprises the steps: reading a lock code through the computer key; determining a function code corresponding to the lock code based on a corresponding relationship between the lock code and the function code; generating an unlocking request based on the lock code and the function code, sending the unlocking request to a server, determining target wiring equipment and target switch equipment in the target equipment through the server, determining the equipment state of the target switch equipment, and sending an unlocking authorization instruction to a computer key based on the equipment state of the target switch equipment; the equipment state comprises an on-off state and an authority release / limit state; and receiving an unlocking authorization instruction sent by the server, and controlling the target wiring equipment to be unlocked. According to the mode, an unlocking mode from bottom to top is achieved, the tedious process of opening an operation order and then unlocking in a traditional mode is not needed, the process is simple and efficient, unlocking of the equipment can be accurately and reasonably controlled, and the safety of the equipment and operators is guaranteed.

Description

technical field [0001] The invention relates to the technical field of equipment control, in particular to a control method, device, computer key and server for equipment operation authority. Background technique [0002] In the field of safe operation in coal mines, it is necessary to carry out operations such as power outages and maintenance of electrical equipment. In related technologies, the management mode of "civil air defense + system" is mainly adopted to ensure the safety of electrical equipment and operators. Specifically, the ticket maker manually prepares the operation ticket. The accuracy of the operation ticket depends on the technical level, experience and responsibility of the ticket maker. There is a lack of judgment on the rules to prevent misoperation, the possibility of misoperation is high, and the process is cumbersome. , low efficiency; in an emergency, the operator relies on the master key to control the electrical equipment, and the operation is mo...

Problems solved by technology

Specifically, ticket drafters manually draw up operation tickets. The accuracy of operation tickets depends on the technical level, experience and sense of responsibility of the ticket drafters. There is a lack of judgment to prevent misoperation rules, the possibility of misoperation is high, and the process is cumbersome. , low efficiency; in an emergency, operators rely on the master key to control electrical equipment, and the operation is random, which further increases the possibility of misoperation, making it difficult to effectively guarantee the safety of electrical equipment and operators
