Application of Remote Wireless Control Technology Based on LoRa System in Intelligent Agricultural Machine

Intelligent agricultural machine has become the development direction of agricultural machinery, a variety of intelligent agricultural machine products have appeared in the market. Like other unmanned vehicles, the safety and reliability of intelligent agricultural machine are the most important. In addition to intelligent decision making, data transmission and remote control are indispensable. The spread spectrum wireless remote control based on long range radio (LoRa) has become an indispensable organic component of intelligent agricultural machinery system. This paper explores the wireless communication mechanism of LoRa, designs and develops the control circuit of ES8H698, a 32-bit general purpose microcontroller based on ARM Cortex-M0 CPU core. It has been tested and applied on the caterpillar spray machine to realize remote wireless information transmission and control, and achieved satisfactory results.
