System Introduction

The coal mine belt transportation monitoring system combines advanced automatic control, communication, computer technology, video monitoring technology, information technology, and modern management technology to control and manage the coal mine transportation production system and statistics as a whole, providing a comprehensive solution to optimize operation, control, management, and unmanned on-site positions, achieving the goal of reducing manpower and increasing efficiency, improving production operation status, safety level, and accident and disaster prediction and forecasting.
The system adopts open programming software and open data channel communication protocol, and can easily and quickly communicate data with the dispatch center or other belt conveyors through optical cables or Ethernet, thereby achieving centralized control of multiple belt conveyors and networked operation of the entire mine and monitoring system.

System Architecture

The system adopts a fully distributed control structure, mainly composed of an industrial computer, upper computer configuration software, mining explosion-proof and intrinsic safety PLC control box, mining intrinsic safety operation console, sensors and protection devices, mining explosion-proof camera, etc.

System Function

The system has monitoring, display, and alarm functions for conveyor belt speed, temperature, smoke, deviation, tearing, slipping, coal stacking, coal transportation volume, power balance, strong conveyor belt wire breakage, decreased conveyor belt tension, motor working voltage, working current, power, and operating status.
The system has automatic, manual, local, and ground remote control functions; Equipped with emergency stop control and locking, as well as voice alarm functions along the line; It has multi machine interlocking and single machine control functions.
The system has control functions for shrinking, retracting, extending, and releasing tapes.
The system has the functions of multi motor speed synchronization control and automatic power balancing.
The system has functions such as super temperature and smoke alarm, sprinkler control, and locking. The system has coal stacking alarm, shutdown control, and locking functions.
The system has deviation and tear alarm, shutdown control and locking functions. The system has the functions of coal level alarm, control, and locking in the coal bunker.
The system has the function of monitoring wire rope breakage in the steel wire rope core conveyor belt.
The system has image linkage function: cameras are installed at the belt head, tail, transfer point, etc., which can display the working status of on-site equipment in real time.
The system is equipped with communication signal devices to achieve start warning, point signal communication, voice alarm, and voice intercom along the conveyor belt. The system has the functions of emergency stop lock and deviation fault location along the belt conveyor.
