水、热、气、电四表合一数据采集系统的研究与应用

Research and Application on Data Acquisition System about Water, Heat, Gas, and Electricity Meters in One

摘要:

目前居民在用的水表、热表、气表、和电表四种表计虽然在抄表付费流程上相似,但由于分属不同部门管理,无法形成资源共享,既浪费工作量又给居民带来不便；文章论述了四表合一的技术构架,提出了从主站,通信信道,现场设备3个方面对现有系统进行升级的方法；首先,介绍了协议转换器的主要设计原理和用电信息采集设备—集中器的上下行通讯协议的改进方法,并且扩展协议转换器多种下行通讯方式以匹配市场上水表、热表、气表通讯方式多样化的现状,在用电信息采集系统平台上增加协议转换器及升级现有集中器程序,通过现场简单布线快速经济的实现四表合一数据采集；按此方案布局的四表合一采集试点,项目建设简洁、迅速,抄表运行稳定,一次性采集成功率在95%以上。

Abstract:

At present, water, heat, gas, and electricity four meters belong to different departments for management. Although similar in meter reading and payment processing, they cannot share the same resources, which is a waste of workloads and inconvenient for users. This paper discusses the technique framework of “four meters in one”, proposed a method of modifying the current system from three aspects, i.e., the master station, the communication channel, and the devices. This paper introduced the main design principle of protocol converter and the improvements of the communication protocols of centralized meter reading terminal, and extending downward communication ways on protocol converter to match the present situation of diversification of communication about water meter, heat meter, gas meter in the market. With the popularity of the smart grid, increase protocol converters and upgrading existing centralized concentrator program on this good platform for the data acquisition, through the simple wiring after the implementation of rapid economic four meters data collection. Using this proposed method, the demonstration projects shows that, it is easy and fast to build, meter reading runs well, and the one-time acquisition success rate is above 95%.
