Underground wireless automatic control device for mining

Abstract

Disclosed is an underground wireless automatic control device for mining, belongs to the technical field of automatic control devices, and is used for wireless automatic control and monitoring of mining underground operating devices. The technical scheme includes that the mining underground wireless automatic control device comprises a plurality of control computers and a plurality of controllers, wherein programmable logic controller (PLC), distributed control system (DCS) and fieldbus control system (FCS) serve as the core of the plurality of controllers, and both the computers and the controllers are placed in an explosion-proof tank which reaches the mining safety level; the control computers and the controllers are connected through wireless signals; and data connections between controllers, between controllers and control computers, between control computers, and between control computers and remote computers are established. According to the underground wireless automatic control device for the mining, wireless connections of underground control can be achieved, controlling staff are enabled to monitor and control automatic operation of various devices in real time; the device can be moved without stop of production during excavation of a roadway and moving forward of a coal cutter, and connection and covering for the whole course of the underground control is achieved. The underground wireless automatic control device for the mining has the advantages of being high in degree of automation, reliable in connection, high in adaptability, comprehensive in control, and the like.

Description

technical field [0001] The invention relates to a wireless automatic control device for underground coal mines, belonging to the technical field of automatic control equipment. Background technique [0002] In the current underground coal mine production, with the advancement of technology and the development of production, the traditional electrical control system is being replaced by the advanced control system with electronic computer as the core. Among the existing control systems, widely used control systems include PLC (programmable logic controller), DCS (distributed control system or distributed control system), FCS (fieldbus control system) and so on. The advantages of these systems are strong adaptability, anti-interference, powerful functions, easy programming of the control system, and ability to record and check data. Among them, the mining automatic control system produced by Siemens Company has solved the problem of underground automatic control production be...

Problems solved by technology

Among them, the mining automation control system produced by Siemens Company has solved the problem of underground automatic control production, but its shortcoming is that it uses wired connection.

During wired connection, the cables must be continuously laid and moved with the change of the working surface. Various control cables not only affect the actions of on-site personnel, but are also easily damaged by on-site machinery and ores. It is difficult, time-consuming and labor-intensive to find out the fault point, which exposes the weakness of the poor adaptabilit
