摘 要皮带运输机是一种连续运输机械，被广泛应用在矿、电厂、港口 Abstract Belt conveyor is a continuous transportation machinery, it is used in production line of mine，power plan，ports，iron and steel enterprises and light industry widely, it can transport the dispersed material, also can transport the items made into pieces. Such a system classifiles the object under investigation as one of numerous possible categories that in return for the current domestic this paper mostly the in-situ human control way to improve, and realize the automatic monitoring, alarm and control. The system uses high-grade microcontroller AVR series of ATmega16 as the master chip, and therefore solve the PLC system as the high cost. At the same time also solved the problem of 51 series singlechip low current, slow processing speed, peripherals circuit complex. The designing monitoring range ,such as monitoring of the belt conveyor skidding of wandering coal longitudinal tear and smoke failure ,and the temperature of Motor bearing and belt environmental . As to realize the transport operation to the real-time monitoring .And add the function that set the alarm temperature value by self,it’s strengthen the system’s adaptability.the system also designed network communication expand interface for customers to choose.
