Design and Application Exploration of Industrial Communication Technology Based on LoRa
For the acquisition and control of some controlled objects in the current process control system,the remote I/O module without CPU has the characteristics of small size,high cost performance and low communication bandwidth require-ments.In order to eliminate the problems of long communication cable laying and limited service life caused by round-trip mobile mechanism such as driving mud suction machine,an industrial data exchange device based on LoRa technology is designed in this paper.The device uses STM32 as the main controller,and realizes wireless data transmission and pro-cessing by SX1262.The practice proves that the communication distance of the device can meet the data exchange re-quirements of each remote I/O module in the production process,greatly improve the agility of the production process control system,and contribute to the construction of the digital production process line.
