Research on the Wireless Meter Reading Technology Applied in Ultrasonic Water Meter based on ZigBee

针对传统户用水表有线抄表方式存在的诸多弊端,提出一种基于ZigBee通信技术的远程无线抄表方法 .首先分析超声波水表的测量原理及通信参数,然后在Z-stack数据透明传输例程的基础上修改协议栈中涉及串口波特率、奇偶校验和消息传输部分的代码.另外,文中还给出了无线抄表系统的整体框架设计和上位机的使用说明.实验测试表明,该系统能够有效替代传统有线抄表方式,具有一定的应用价值.

In view of the traditional cable meter reading way of household water meter, there existing many disadvantages. One kind of remote wireless meter reading method based on ZigBee communication technology has been proposed. First, the measurement principle and communication parameters of the ultrasonic water meter are analyzed. Then, on the basis of Z-stack data transparent transmission routine, we modify the code in the protocol stack, which involves serial port baud rate, parity check and message transmission part. In addition, the overall frame design of the wireless meter reading system and the instructions of the use of the upper computer are also given. The experimental test shows that the system can effectively replace the traditional mode of cable meter reading, and has a certain application value.
