Intelligent conveying system of main coal-flow in mine

Intelligent conveying system of main coal flow in mine  

Product Overview

KTC197 communication control system for conveyor is suitable for mines with explosive gas (methane) and coal dust, and can be used for comprehensive mining and excavation working surface, and realize the centralized control and protection of underground coal mining and coal transportation system such as scraper conveyor and Belt Conveyor in the tunnel.

The system host takes high-performance PLC as the main control unit of the control system to collect and process information from Various Sensors in real time, realizing the functions of communication, control, comprehensive protection, call along with the line, fault positioning, animation display and voice alarm for the whole system. It has rich communication interfaces such as RS485, CAN and Ethernet, which can meet the special communication requirements of different customers on site.

Application scope

The solution integrates intelligent control for belt conveyor system, telephone dispatching and video surveillance of, and constructs a complete dispatching, operation and monitoring network system. It can not only improve the production efficiency of equipment with safety, save resource consumption, reduce the operation personnel, but also realize the unattended and intelligent operation of the belt conveying system. It is suitable for the comprehensive requirements of intelligent control and management upgrading of underground and surface belt conveyors and their related subsystems. It is a customized solution for high-end customers who meet the requirements of unattended system and intelligent operation of mines.

Main functions

The solution takes the safety, reliability and intelligence level of intelligent control of conveyor system as the core, taking real-time detection and monitor the key information of main equipment and hoist process, remembering the faults, remotely transmitting and storing the data and information, intelligently analyzing and specialized processing the invisible fault information. Fully realize the self-diagnosis of equipment and system, explicit fault alarming, invisible fault warning and so on, supporting the uploading of management information and control command transmission. With the intelligent function of "system plug-in", which is convenient to realize the information interaction with other information systems to meet the needs of the realization and operation of intelligent mines.

“5+1+2” Intelligent Control Solution for Conveyor System

This scheme has two sets schemes of underground and surface by considering environment. The main difference between these two schemes are explosion proof and protection grade caused by the environment of using equipment, the other main control functions and performance are basically the same.

“5+1+2” scheme include

This scheme includes the Conveyor Automation control system, conveyor energy consumption management system, conveyor expert intelligent system (equipment level), audio communication system, video surveillance system, network communication and data remote transmission channel, dispatching management and monitoring platform, remote service platform consisting of five subsystems, one channel and two support platforms.

1. Conveyor Automation Control System

The conveyor Automation control system takes the high performance PLC as the core control device, and the single Belt Conveyor Control takes the embedded single chip microcomputer as the core control device. The whole system runs in the high efficiency and low consumption mode of "start with coal, stop without coal, fast with more coal, slow with less coal", which has the characteristics of advanced technology, stable performance, safe and reliable, good economy and low energy consumption. By collecting and processing the working condition information of each sensor in real time, the operation condition of the equipment is accurately judged, it also has the functions of communication, control, protection, fault location, animation display and voice alarm. It can meet different special control and communication requirements at user site.

2. Conveyor Energy Consumption Management System

The actual load of each conveyor belt is accurately measured through professional and reliable detection and a complete intelligent control algorithms. Taking the belt conveyor system as a whole, the system adjusts the running speed of each belt machine, so that it runs in the high efficiency mode of "start with coal, stop without coal, fast with more coal, slow with less coal".

3. Conveyor expert intelligent system (equipment level)

Mainly include: hardware facilities of industrial control computer, displayer, special collection card, communication network, as well as application software packages of monitoring software expert think tank. The main software function modules include equipment management module, equipment condition monitoring module, fault information management module, system condition reproduction module, expert think tank module, Remote Diagnosis module.

4. Audio Communication System

The voice call requirements along the conveyor line are easily solved through the intrinsically safe amplifying telephone (including emergency stop) installed along the system.

5. Video Surveillance System

Load point, transfer point, unloading point, crusher, coal bunker, workstation and other place needs monitoring;

6. Network communication and data remote transmission channel

The signal is transmitted to the dispatching command center through LAN to provide hardware and software interface support.

7. Dispatching management and monitoring platform

If the dispatching system has application software, data interaction can be carried out directly after shaking hands approved by both parties. If there is no application software, the application software can be provided to realize the application requirements.

8、Remote service platform

Remote service platform support system (Locate in Jiaozuo, Henan Province, serving national customers): based on reliable network security mechanism support to achieve remote diagnosis of equipment and other intelligent functions through the public network. Remote detection and high-quality service is available for hoist, belt conveyor, main ventilator and other large mine equipment.
