污水处理已经成为当前工业领域发展的一个重点,其技术更加先进,规模更加大,所以控制和监控设备日益复杂、性能日益提高。以前的手动控制和老的监控模式已经不适合污水处理控制系统的发展。为此构建了一种基于OPC技术和Modbus/TCP实时以太网的现场总线技术的分布式污水处理控制系统体系结构,实现现场设备和监控软件的无缝集成。 Sewage treatment has become a focal point in the development of the current industrial field. Its technology is more advanced and larger in scale. Therefore, control and monitoring equipment are increasingly complex and their performance is increasingly enhanced. Previous manual control and old monitoring mode is not suitable for the development of sewage treatment control system. To this end, a distributed sewage treatment control system architecture based on OPC technology and Modbus / TCP real-time Ethernet fieldbus technology is constructed to realize the seamless integration of on-site equipment and monitoring software.
