Abstract:

According to the problems of incomplete kind and low reliability of protection of mine belt conveyor, the paper designed an intelligent protection system of belt conveyor based on C8051F020 and RS485 buses, analyzed common faults of belt conveyor, introduced hardware structure and software design of the system. Identified measuring methods of belt faults of speed, temperature, fog and disalignment. The protection system used host computer and slave computer two levels system to collect and process various signal parameter output by system’s sensor, which realized real-time speed detection and intelligent judge of belt conveyor faults, reduced malfunction rate.

Key words: belt conveyor, intelligent protection, C8051F020
