Design of Digital Electric Parameter Measurement System Based on CAN Bus

介绍了一种基于CAN总线技术的数字电参量测试系统的设计。在硬件上完成以51单片机为核心,对数据的采集、显示及存储等功能模块进行设计,用SJA1000控制器和TJA1040驱动器设计CAN接口电路,实现CAN通信功能。在软件上,按照模块化程序设计思想完成了系统软件部分的设计。本系统具有硬件结构简单、实时性高的优点。能完成对现场电参量的实时检测,具有广泛的应用价值。

This paper introduces the design of digital electric parameter measurement system based on CAN bus, including based on 51 single chip, data acquisition, displaying and storage modules. In hardware circuit design,SJA1000 is as the controller of CAN.In software,realizing parts of functions according to modularization program design. The system with simple hardware structure and high real-timing can real-time measure the spot electric parameter,which has widespread applied value.
