摘要
企业综合信息自动化系统是一个复杂系统,要在设备、数据库和应用软件间建立通用、高效的数据读取机制,由于设备的多样性和驱动程序的不兼容性,难以实现系统的无缝集成.笔者对实现控制系统现场设备与过程监控级进行信息互连、实现控制系统开放性的关链技术OPC作了讨论.
An information system of comprehensive automation in enterprise is a complex system. The computer integrated plant automation is based on the realization of integration between control and management in the system. Therefore the Data access mechanism has to be established among devices, databases and application software in high efficiency and universal manner. It is difficult to realize seamless integration among different systems. Because of device variety and non-compatibility of drive program. This paper makes a brief discussion for information interconnection between field devices of control system and supervisory control systems, and also for key technique of OPC in openness.
