多种监控系统基于CAN总线的联网设计

介绍了基于CAN总线的多种监控系统联网设计,该设计应用DDE(动态数据交换)技术实现VB程序与多种组态软件开发的SCADA系统的数据交换,通过调用动态链接库函数完成总线的数据通信,从而搭建了工业现场的信息化管理平台.

This paper introduces the multi-SCADA system net wo rk design based on CAN bus. The design applies DDE (dynamic data exchange) techn ology to realize data exchange between VB program and SCADA system, and complete s data communication of CAN bus by using dynamic link library functions. The inf ormation management platform of industry field is then constructed
