【摘要】 针对当前污水处理控制系统的规模不断扩大、监控设备日益复杂、性能日益提高的状况,传统的监控模式已经制约了污水处理控制系统的发展。为此构建了一种基于OPC技术和CAN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。结合着活性污泥法污水处理工艺流程,说明了监控系统的硬件基本结构。给出了采用VB6.0开发了OPC客户端应用软件的标准OPC接口的程序。在实际应用中该方法取得了良好的效果。更多还原

【Abstract】 Aim at the condition that control scale is extending continuously,equipments become complicated and its function raise increasingly in the process of sewage disposed monitor system,traditionary monitor mode have restricted the development of sewage disposed monitor system.A distributed system structure of sewage disposed monitor system based on OPC technology and CAN-FieldBus technology was constituted.Seamless integration between locale equipment and monitor software was carried out.The hardware structure of the monitor system was introduced associated with the sewage disposed craft.The program developed by VB6.0 of the OPC interface of OPC client application software was provided.The experimental result shows satisfactory feasibility of the method.更多还原
