ABSTRACT
To ensure the operation in underground transport system reliable and safe in coal mine, it is very important to carry out automatic control of belt conveyor for raising the level of automatic management.
On the basis of analyzing centralized control function of belt conveyor,we design the automatic control system with the single belt and a single machine which based on S7-300 type PLC. The system is composed by the operation flat and the PLC, The operation flat is used to control flat and display running information real-time, and PLC is used to collect field information and control belt real-time.
In this paper, the composition and function of the belt control system is introduced firstly. Structure of hardware is confiremed and the equipment selection is also completed.Then the software design is conducted. At last,the anti-jamming measures of belt control system is represented.
