Main unit of protection and control device for coal mine belt conveyor

1、 Purpose:

The host of KHP360-K-Z coal mine belt conveyor protection control device (hereinafter referred to as the host) is a new generation of mining controller that integrates advanced electronic technology, PLC technology, automation technology, communication technology, and anti-interference technology, with mining intrinsic safety PLC as the control core. This substation has high reliability and cost-effectiveness, powerful communication capabilities, LCD Chinese character display, rich operation and function buttons, voice alarms and other characteristics. It is an intelligent control device suitable for use in hazardous environments such as coal dust and gas. It has wide universality and strong adaptability, and can achieve automatic detection, monitoring and control of belt conveyors in various occasions.

This substation is suitable for hazardous environments such as gas and coal dust explosions underground in coal mines or harsh ground environments. It can also be used as a comprehensive protection for belt conveyors in harsh environments such as metallurgical mines, open-pit coal mines, ports, coal preparation plants, power plants, etc., replacing various existing belt conveyor comprehensive protection devices. It can not only automate the control of standalone devices, but also form a network system to achieve distributed and hierarchical remote monitoring and management.

2、 Performance characteristics

1. High reliability: With high-performance intrinsically safe modular PLC as the processor, it has strong anti-interference ability and high reliability, ensuring stable and reliable operation of the control system, and collecting real and effective data, especially suitable for environments with harsh conditions.

2. Human machine interface: The panel of this substation is equipped with an intrinsic safety human-machine interface, which uses a touch screen. The operating status, fault location, and fault nature of the controlled equipment can be displayed in the form of Chinese characters, symbols, or charts. The information is intuitive, and the parameters can be set using the touch screen for easy operation; 12 function buttons, combined with the current display interface of the human-machine interface, can achieve more functional operations and meet various complex control scenarios.

3. Powerful communication capability: Unique patented technology is used in the communication interface circuit, with long communication distance and strong anti-interference ability, making it easy to form a multi-level remote communication network.

4. Convenient wiring: Adopting a universal control box wiring method, the terminal numbers are clearly labeled, the wiring space is large, and users can easily and conveniently connect wires without any problems such as wiring difficulties.

5. Small size and light weight: The mechanical circuit adopts modular design, compact structure, small space occupation, and the entire device has a relatively small volume and weight, making installation and transportation very convenient.

6. Wide applicability: The intrinsically safe PLC of this substation serves as the control core, and programs can be easily customized according to different on-site requirements, greatly reducing the project cycle.

7. Multiple operating modes: It has multiple operating modes such as single unit, centralized control, maintenance, and jog to meet the various needs of users.

8. Complete protection function: In addition to the usual belt conveyor comprehensive protection function, this substation also has multiple functions such as fault unlocking, manual watering, parameter setting, etc.
