Remote operation control method applied to centralized management and control of equipment

Abstract

The invention discloses a remote operation control method applied to the centralized management and control of equipment. A centralized management and control terminal and an equipment operation terminal can be both used as a requesting party and a requested party; the requesting party sends electric signals for requesting an operation authority to a PLC (Programmable Logic Controller); the PLC sends first electric signals to the requested party and judges whether the requested party allows the requesting party to obtain the operation authority or not; if the requested party allows the requesting party to obtain the operation authority, the PLC sends second electric signals to the requesting party, and the requesting party obtains the operation authority; if the requested party does not allow the requesting party to obtain the operation authority, the PLC sends third electric signals to the requesting party, and the requested party obtains the operation authority; the requesting partyor the requested party which obtains the operation authority sends an operation instruction to the PLC; and the PLC controls an equipment actuator to complete operation according to the received operation instruction. According to the method of the invention, through mutual handover of the operation authority, only one of the requesting party and the requested party has the operation authority inthe same time period, namely, only one device controls the equipment, so that the safety of the operation of the equipment is improved.

Description

technical field [0001] The present application relates to the technical field of equipment management, in particular to a remote operation control method applied to centralized management and control of equipment. Background technique [0002] The production process of iron and steel enterprises is complex, and there are many energy media. Enterprises need to balance the energy media of each process, realize the recycling of media, and reduce the energy cost of enterprises. Therefore, many iron and steel enterprises have set up energy management and control centers to centrally allocate and balance the energy of each production process. medium. [0003] At present, the management and control center realizes the measurement of energy data in each process through energy metering instruments, data acquisition PLC controllers scattered in each process, data acquisition software and network, and through data analysis, controls the equipment of the medium pipeline through the huma...
