**§1 Introduction** The safety and reliability of the centralized control system for coal mine conveyor belts directly affect the economic benefits of the mine. To improve the reliability and safety of the system, centralized monitoring and comprehensive protection are essential. The intelligent conveyor belt centralized control and monitoring system produced by Tangshan Kaicheng Electric Co., Ltd. is a high-tech product applied to the automation of mine conveyor belt transportation. This system is based on the "Coal Mine Safety Regulations," summarizes accidents that occur during mine transportation, and is a new generation of comprehensive control system developed with high safety, strong practicality, and advanced features. The centralized control system, together with the dispatch telephone system and industrial television system, constitutes a complete operation, dispatch, and monitoring network, realizing remote measurement, remote signaling, and remote control of the entire system. This system can improve production efficiency, reduce accident rates, reduce fault handling time, reduce on-site operators, and improve economic benefits. **§2 Description of the Centralized Control System** Currently, PLCs remain the mainstay in the field of industrial automation control, providing highly reliable control applications for various automated control equipment. The main reason for this is that it can provide a safe, reliable, and relatively complete solution for automation control applications, suitable for the current automation needs of industrial enterprises. In the global industrial computer control field, significant changes have occurred surrounding open process control systems, open process control software, and open data communication protocols. With the birth and further improvement and development of PLC (SoftPLC) control configuration software technology, process control systems based on industrial PCs and equipped with SoftPLC configuration software are gradually developing. For control software, the core of the PLC controller is providing open programming and configuration tools to industrial users. Furthermore, breakthroughs have been made in open communication network technology, resulting in the integration of PLCs into more open industrial automation control. This system adopts a fully distributed control structure, consisting of an underground control station and a comprehensive operating console. The comprehensive operating center is located in the central control room on the surface. The system uses AnS and FX series PLCs from Mitsubishi Electric Corporation of Japan. The control master station and control substations are connected via Mitsubishi Electric's open CC-Link network bus structure. The control substations and sensors are connected via a matrix structure. The control master station and the monitoring host computer of the comprehensive operating console are connected via a CC-Link bus network. The control substation is responsible for data acquisition and control of field equipment. Through monitoring, the equipment of the entire system can be monitored and centrally controlled.
