Abstract

The invention discloses a PLC architecture for a mine communication control system and the mine communication control system. The PLC architecture comprises a detecting module, a coupling module, a voice conversation module, an intrinsic safety input / output module, a communication module and a PLC; the detecting module transmits a telephone audio signal and a dual audio signal along a line to thevoice conversation module, and transmits an equipment state signal and a blocking signal along the line to the PLC through the communication module; the coupling module feeds the voltage along the line back to the PLC and the voice conversation module in the mode of dual audio; the voice conversation module converts the received audio data stream into an audio analogue signal and plays the audio analogue signal after amplifying the audio analogue signal; the intrinsic safety input / output module acquires a belt equipment protection signal and motor state information, and transmits the belt equipment protection signal and the motor state information to the PLC; and the PLC realizes the control of equipment and belt equipment along the line on a working surface.

Description

technical field [0001] The present disclosure relates to the technical field of mine communication, in particular to a PLC controller architecture of a mine communication control system and a mine communication control system. Background technique [0002] At present, the country attaches great importance to coal mine safety production, staff reduction and efficiency increase, and coal mine production automation has become an inevitable trend. The original personnel manually controlled mechanical coal mining in sections, and gradually improved to an intelligent, centralized, safe, efficient, energy-saving and consumption-reducing production mode. The equipment that needs to be controlled extends from a single working face and belt face to the entire mining area and even the entire mining area. [0003] During research and development, the inventor found that the hardware in the existing mining communication control system has problems such as poor EMC protection performance...
