基于LoRa的多传感器低功耗数据采集方法
Method of multi-sensor low-power data acquisition based on LoRa
摘要
Abstract
In allusion to the problem of invalid wake-up of sensor nodes in a multi-sensor acquisition system,which based on the same LoRa communication channel,a low-power working method based on wake on radio strategy and channel switching mechanism is proposed.In this method,the LoRa communication link is divided into multiple communication channels,the switching and time division multiplexing of different channels are conducted,and group communication of multiple sensor nodes is realized,avoiding ineffective wake-up from sensor nodes and minimizing communication power consumption of slave nodes under limited channel capacity.A LoRa local area network sensor communication instruction protocol is developed,which can realize the low-power active polling collection,fixed-point debugging,and early warning reporting of multiple sensors.The experimental results demonstrate the effectiveness of the proposed method.关键词
