摘要
为了解决用电信息采集系统实施中离散安装的电能表的数据采集问题,提出了采用无线通信方式取代离散安装的电能表与用电信息采集系统RS485总线之间的布线,在综合考虑了DL/T 645通信规约的要求、设计成本、通信可靠性及相互干扰等因素后,提出了无线RS485中继器的设计方案。该无线RS485中继器的实现可以大大减少用电信息采集系统的现场实施难度,从而推进用电信息采集系统的建设。
In order to solve the problem of data acquisition from discretely installed energy meters in the implementation of electric energy information acquisition system, this paper presents a scheme using wireless communication mode to replace the cable wiring between the discretely installed energy meters and the acquisition system RS485 bus. After comprehensive consideration of factors of requirement of DL/T 645 communication protocol, design cost, communication reliability and mutual interference etc., a design scheme has been proposed, the realization of this wireless RS485 repeater can greatly reduce the on-site implementing difficulty of the electricity information acquisition system, thus speeds up the construction of electric energy information acquisition system.
