摘要
结合自动化立体车库检测控制系统,文章中较详细的论述利用VisibleBasic6.0中的ActiveX控件MSComm通讯控件实现监控机与PLC之间的一种通讯方法,并能实时检测现场设备状态。实践证明该通讯方式简单、稳定、可靠,并能满足通讯要求,具有一定的实用价值。
Combining the automatic supervising and controlling system of three-dimension parking lot, this paper describes the method of communication between monitoring computer and PLC(Programmable Logic Controller) using the control-ActiveX in VB6.0 in detail which monitors the state of equipment in real-time. It is proved the mothod of reliability, simpleness and stability in practice, and it can satisfy the need of communication. It has practical value.
