摘　　要：监控系统对工业生产非常重要,可编程控制器PLC和可视化程序设计语言Visual Basic以其优越的性能应用到这一领域。在Visual Basic与PLC串行通信的基础上,实现了PLC对发电机电网频率的测试和对集水井水位的控制,并开发了基于Visual Basic的监控系统。Monitoring system plays a very important role in the. industrial production, Programmable Logical Controller and visual program design language Visual Basic are used in this area by right of their excellent capability. It achieved the serial communication between Visual Basic and PLC, on the basis of this, it achieved frequency testing of generator and electric network and water level control of storage well by way of PLC, meanwhile,it exploited monitoring system based on Visual Basic.
