A New Module Approach of Synchronous Remote Pulse Electrical Meters Data Capture Method

本文介绍一种基于CAN总线的新型海量脉冲电表群同步数据自动采集模块的研究。具体阐述了该研究成果的嵌入式微处理机的软件、硬件上的实现方法。该方法解决了以往电表通短电时漏计或复计脉冲,特别是解决了海量电表的脉冲数据的精确、高效和抗干扰能力等问题。CAN总线的应用,解决了局部表计群采集模块之间的高抗干扰,快速信息交互的问题,实践证明,该技术具有稳定、便于安装、维护和在系统频繁电源掉电时依然对脉冲电表群具备实时、准确、可靠的计量的能力。

A scheme of Remote Pulse Meter Reading System based on CAN bus is put forward. The method presents the software and hardware implementation of this module. The module can successfully capture remote pulse meters＇pulse outputs totally with high communication speed and strong anti-interference without any loss counting of the pulses of the meters. So the real-time,precise, reliable meter reading can be ensured.
