Abstract: In order to improve the automatic and intelligent level of the tractor monitoring system, it applied the adaptive fuzzy algorithm to the design of the tractor monitoring system. Through the adaptive genetic algorithm and fuzzy PID feedback regulation, it realized the intelligent monitoring of tractor fault and operation quality. In order to verify the role of the adaptive fuzzy algorithm in the monitoring system, it set up a wireless sensor network in the field operation area, and it counted the remote monitoring fault diagnosis results. The statistical results show that the adaptive fuzzy algorithm is more accurate than the diagnosis results without the intelligent algorithm, which is very important for improving the accuracy of the monitoring system.
