摘要
针对现有无线抄表系统功耗高、数据传输距离短、可靠性低的缺陷,设计了一种新型的无线抄表系统。以STM8系列低功耗微处理器为核心,Contiki为操作系统,采用LoRa通信技术,使用自定义网络通信协议,实现了对超声波水表的流量数据采集和远程管理,满足了低成本、高效率抄表的需求。系统测试结果表明,该无线抄表系统功耗低、数据传输距离远、可靠性高、组网便捷。
Aiming at the disadvantages of the existing wireless meter reading system with high power consumption,short transmission distance and low reliability,a new wireless meter reading system is designed.The system takes the ultra low power STM8 serials microprocessor as the core,Contiki for the embedded operating system,and uses LoRa communication technology and custom network communication protocol,realizes the flow data acquisition and remote management of ultrasonic water meter,which meets the demand of the low cost and high efficiency meter reading.The final tests indicate that the system has good performance in terms of power consumption,transmission distance,reliability of data transmission and building network.
