Abstract Belt conveyor is a efficient and continuous equipment to transport material. Due to the complex environment and the severe conditions in coal mine,belt conveyor is damaged easily, as a result, which not only affect the production, but also is a serious threat to the safety of staff in the underground. The design based on "Coal Mine Safety Regulations", to design a belt conveyor monitoring system and microcontroller is the core of the design. The design monitor and protect some common faults in it, and the host computer make some analysis and decision on the basis of data to make some protection to promote it works. This system can greatly improve production efficiency and safety in coal production .
Since the coal production, belt monitoring system must realize the stability and efficiently of the belt conveyor system. belt monitoring system collect and process important information data by transducing and measuring technique, and realize the monitoring and protection of possible sliding, belt conveyor running deviation, tearing and so on conditions, at last realize remote automatic control. In the system, AT89C51 microcontroller give full play to its high reliability, easy extension, low voltage control capability, low power consumption, cost-effective features, ensure operation of belt monitoring system safely and reliably.
The system is inexpensive, applicable, high reliable and fully functional, thus it greatly reduced the demand of manpower and material resources. At the same time, which ensure safety in production and improve the production efficiency and economic benefit in coal mine.
