Based on Lora wireless communication, a new industrial robot remote monitoring system is designed. The system hardware mainly includes four parts: main control chip, industrial robot interface, power supply circuit and displacement sensor. The main control chip is sx1265 / 7 / 8 RF chip, stm32f1103c8t6 MCU main control chip is selected as the networking processing hardware of Lora wireless communication, the signal chain is established according to the performance of MCU main control chip, the SPI interface is used to associate the interface between sx1276 wireless transceiver and MCU equipment, the lithium battery is used as the power circuit, and the power supply voltage of lithium battery is stabilized through ame8800aetl voltage stabilizing chip, Wxy31 pull wire displacement sensor is used to realize sensing. Lora wireless communication technology is introduced to establish the storage sequence of Lora wireless communication signal, receive the monitoring instructions issued by the acquisition platform, update the working state of the robot on the display screen, and realize the operation of remote monitoring software. The experimental results show that the anti-interference ability of the industrial robot remote monitoring system based on Lora wireless communication is effectively strengthened and the power consumption is significantly reduced.
