Design and Application of Running State Detection System for the Oscillating Subsoiler Based on CAN Bus

In view of problems such as difficulty in measuring state parameters and disturbance in the process of agricultural machinery, the monitoring system is designed for running state of the oscillating subsoiler based on CAN bus, to collect the deep loosening machine running speed, tractive resistance, the temperature and humidity of the environment, vibration frequency of key point and electrical system status for fault detection. A master control system based on mega128 and C8051F040 and several slave independent sensor node based on C8051F040 could build a intelligent monitor network via CAN Bus. The parameter of machine working state can be set, displayed, storage, and block positioning information by GPS and related operational data could be uploaded to the far range control center through GPRS network. The results show that the system is stable and reliable, and can adapt to the different working condition of the oscillating subsoiler.
