用电信息采集终端通信硬件端口自动化接驳和本地通信方案的研究与实现

目前,电力用户用电信息采集终端的功能检测主要采用人工插接RS-232端口,建立检测装置与终端本地通信的方式为主,虽然该方式成熟可靠,但存在检测效率低下和难以实现自动化操作等问题。因此,本文提出扩展采集终端RS-485抄表辅助端子功能,用以实现RS-485抄表口为采集终端本地通信口,开启RS-485辅助端子本地通信和参数设置功能的方案。该项研究巧妙解决了目前制约采集终端通信硬件端口自动化接驳和同时实现本地通信的技术瓶颈,因此,具有重要的突破性意义,也为推动实现采集终端的自动化检测系统定型和推广应用提供了可靠的解决方案。

The electric energy data acquisition terminal communication hardware portautomatic feeder and local communication scheme Research and Implementation

At present, the power user electric energy data acquisition terminal function detection by manual inserting the RS-232 port, a detecting device and a terminal local communications, although it is mature and reliable, but there exists the problem of low detection efficiency and difficult to realize automation etc.. Therefore, this paper extends the acquisition terminal RS-485 meter auxiliary terminal function, to realize RS-485 meter reading for the acquisition terminal local communication port, open the RS-485 auxiliary terminal local communication and parameter setting function scheme. The study resolves currently restricting the acquisition terminal communication hardware port connection and realize automation technology bottleneck, the local communication and therefore, has the important breakthrough, but also to promote the realization of automated detection system of the collection terminal type and application provides a reliable solution.
