摘　　要：高速公路及隧道监控系统中,没有现成可用的I/O驱动,无法直接通过组态软件的I/O驱动获取数据。只能通过用户编写大量复杂的通信程序与之进行数据交换。为降低开发难度、提高开发效率,提出在组态软件脚本语言环境下运用API函数实现系统的通信设计。该系统以iFIX组态软件为平台,开发上位机监控系统软件,系统硬件部分搭建了以光纤作为传输介质的PLC冗余环网。运行结果表明,该系统占用资源小、维护方便、通信稳定且数据传输率高。Freeway and tunnel monitoring system has no ready available I/O drive, cannot access data directly by configuration software I/O drive. They can only exchange data in the way users write plenty of complicated communication programs. In order to reduce the difficulty of development and raise the development efficiency,using API function to realize the communication design under the condition that configuration software script language is put forward.The system regards iFIX configuration software as platform to develop PC monitoring system software; The system hardware part built PLC redundant nets whose transmission mediumis is optical. It is proved on the running spot that the designed program occupies less resource,maintains more conveniently, stable and high rate of data transmission.
