基于LoRa的低功耗温度采集传感器系统设计
Design of Low Power Temperature Acquisition Sensor System Based on LoRa
摘要
Abstract
Aiming at the problem of long-term operation and high maintenance cost of industrial blast furnace cooling water temperature monitoring,a remote low-power wireless sensor network system based on LoRa(Long Range)was designed.The system built a module energy consumption calculation model based on LoRa communication water temperature acquisition terminal.Through the analysis of the calculation model,a wireless communication strategy based on the clock synchronization protocol of LoRa protocol layer and the joint optimization of time division multiple access was proposed.This strategy used LoRa communication technology to complete information interaction and achieve high-precision clock synchronization between gateway and terminal node.The gateway completed the scheduling of wireless resources and dynamically allocated the timeslot resources of terminal nodes,so as to realize the periodic upload of data,reduce the probability of data transmission collision,and optimize the use efficiency of wireless resources.The experiment showed that this communication strategy significantly improved the delivery rate and energy efficiency of communication compared with ALOHA communication protocol,and further improved the performance of LoRa in the network.The jointly optimized wireless communication strategy proposed in this paper is effective.关键词
