Optical fiber type mining flame-proof type remote control device

Abstract

The invention provides an optical fiber type mining flame-proof type remote control device aiming at the shortcomings that an existing cable type mining flame-proof box can easily produce arc spark, is complex in wiring arrangement and single in function, and the like. The optical fiber type mining flame-proof type remote control device comprises a flame-proof penal, a box body and cable connector, an induction type button unit, an induction type shift switch unit, a liquid crystal display unit, an optical fiber connector and a photoelectric signal processing and switching unit. The optical fiber type mining flame-proof type remote control device has the advantages that the situation that arc spark is produced when a traditional button is pressed is completely avoided, operation of equipment in a pit can be controlled closely and in real time and also can be controlled remotely from a monitor room above the pit, and operating personnel in the pit can conveniently know actual operation situations in pit area and carry out right and timely operation aiming at emergency problems in the pit. Due to the fact that optical fibers are adopted to be a connection way between an operation platform and ground control, interference of complex environment in the pit to signals is reduced to the maximum limit. Besides, optical fiber type mining flame-proof type remote control device is far in transmission distance of optical fiber communication in the pit, low in signal loss and little power consumption, and wiring arrangement is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of remote electrical control, in particular to an optical fiber type mine flameproof remote monitoring device. Background technique [0002] At present, the driving control of the underground electrical equipment used in the underground operation of coal mining usually adopts a control method that takes into account both the underground field control and the remote control of the central control room above the mine and can be converted to each other. Because coal mines contain flammable and explosive gases, in accordance with the relevant safety regulations of the country and related industries, traditional cable-type explosion-proof button boxes are generally used for on-site drive control of underground electrical equipment in the industry. The control principle of this traditional explosion-proof button box is: first, the button of the explosion-proof box is touched to generate an electrical signal, and t...
