Abstract: It first introduces the overall structure of the micro tillage machine communication system and the steering control structure. Then, based on the MSP430F149 microprocessor, it designed the wireless radio frequency SYNF115 sending module and the SYN480R receiving module, the hardware part of the micro tillage machine communication system. Combined with the software part, a micro tillage machine communication system based on big data and wireless communication is implemented. The test results show that the wireless remote controller can control the advance, stop, left and right steering of the micro tiller, and the actual control distance can reach 1.5km, which verifies the feasibility of the system.
