Centralized Control System for Multiple Belt Conveyors Based on PLC and Configuration Software

There are many problems such as deviation, skidding, longitudinal tearing and abrupt stopping during belt conveyors transmission. In order to facilitate operators to timely understand the status of long-distance belt conveyor, a centralized control system is proposed based on PLC and configuration. SIEMENS PLC is used as the main and subordinate control system. The Asiacontrol Kingview software is used as a host computer real-time monitoring interface. With the combination of different types of protection sensors, the signals are acquired, transmitted and communicated in order to monitor a number of belt conveyors. The practical application shows that the centralized control system has a good ability of fault self-diagnosis. Thus it ensures the safety of long-distance transportation and improves the automation and intelligence level of the transportation equipment.
