基于塑料光纤的用电信息采集系统研究与设计

阐述了塑料光纤（plastic optical fiber,POF）的特点,分析用电信息采集系统对于通信的典型要求,提出了一种基于 POF的全光纤用电信息采集系统的设计方案。此方案结合 POF和石英光纤两种光纤的优势,将二者分别用于本地通信和远程通信,可使智能电表与主站之间实现实时通信,具有可靠性高、功耗低、投资相对较小的优点。对于智能电表集中安装的城区以及电力光纤到户的智能小区,这是一种用电信息采集的理想方案。

Electricity Information Collection System Based on Plastic Optical Fiber and Its Design

Characteristic of plastic optical fiber was stated,typical requirements for communication of electricity information collection system were analyzed and a kind of design scheme for all fiber electricity information collection system based on POF was proposed.By combining advantages of POF and silica fiber,this scheme was designed to use these two fibers re-spectively in local communication and remote communication which would realize real-time communication between intelli-gent meter and the master station and was provided with merits of high reliability,low power consumption and comparatively small invest.It was proved to be an ideal scheme for electricity information collection to those city areas that intensively installed intelligent meters and intelligent residential districts which realized power fiber to the home.
