The design of electricity information acquisition system based on POF

为解决用电信息采集系统通信实时性和可靠性不高的问题,提出了一种基于塑料光纤的用电信息采集方案,并设计了一种基于塑料光纤的通信模块。论文首先介绍了用电信息采集系统的架构,分析了塑料光纤的特点;然后采用塑料光纤作为本地采集的传输通道,结合串联和并联的方式进行组网,设计了一种用电信息采集方案;再根据塑料光纤与电表接口的通信协议,设计了一种基于塑料光纤的通信模块;最后现场进行了试挂实验,试验结果表明该方案具有良好的通信实时性和可靠性。

In order to improve the performance of real-time communication and reliability in electricity information acquisition system,a proposal of electricity information acquisition based on plastic optical fiber has been put forward and a communication module using plastic optical fiber has been designed. This paper introduces the frame work of electricity information acquisition system and analyzes characteristics of plastic optical fiber. As a local transmission channel,combining with series and parallel connection,plastic optical fiber can be designed for networking,which exists in electricity information acquisition system. According to the communication protocol between plastic optical fiber and electric meter interface,a communication module using plastic optical fiber can also be designed. Perfect performance of real-time communication and reliability was indicated by the result of field test.
