随着社会经济的迅速发展,污水处理成为环境保护的重要环节,迫切需要对污水处理过程进行先进控制和优化。目前,LabVIEW在工业自动化领域已经有了一些成功应用,但在污水处理系统中却少见报道。本文详细描述了基于LabVIEW的污水处理监控系统的体系结构和软件设计方案,利用SIMATIC.NET建立OPC服务器,为监控提供信息采集接口,并提出了避免通讯阻塞,减少实时数据采集延迟的优化策略。该系统应用于上海达能污水处理厂,可靠、稳定,很好的实现了对污水处理各工艺单元中控制对象的实时监控。
With the rapid development of socio-economic, sewage treatment has become an important part of environmental protection and it demands for advanced wastewater treatment process control and optimization. Currently, LabVIEW in the industrial automation field has been used in some successful applications. However, it is rarely reported in the field of wastewater treatment systems. This paper describes the wastewater treatment LabVIEW-based monitoring system architecture and software design. Establish the OPC server by SIMATIC.NET to Provide a Information acquisition interface for monitoring. It proposes some strategies to avoid traffic congestion and reduce delay in real-time optimization of data acquisition. The system is running in Shanghai Danone sewage treatment plant Reliable and stable for monitoring the sewa ge treatment process unit.
