- Abstract:
- Taking Wuhan Beihu sewage treatment plant (STP) with treatment capacity of 80×104 m3/d and the pre-treatment stations of the supporting Dadonghu sewage tunnel as an example, the network nodes, sites and data characteristics involved in the production monitoring system are deeply analyzed and studied. Heterogeneous network integration technology is applied to integrate not only the data center access of the networks within the STP such as station automatic control SCADA system, electrical monitoring ECS system and video image VMS system, but also the signal fusion access of the pre-treatment stations of Dadonghu sewage tunnel network outside the STP as well as the production information release of the management department, the outside superior department and the supervision department. Fault tolerance technology is widely applied to ensure the reliability, stability and accuracy of signal transmission at each node. Super integration and virtualization technology is applied to implement virtual pooling deployment of real-time data servers, historical data servers and WEB servers of the monitoring system in data center infrastructure. Object-oriented component realization method is applied to normalize and release various equipment attributes in the data center for the operators to monitor industrial control signals, electrical operation parameters and video image signals of equipment in the whole STP and pipe network pumping stations (pre?treatment stations) more intuitively through a data center platform, thus to eliminate the isolated information island caused by multi-system deployment in traditional production monitoring systems. Since Wuhan Beihu STP started operation in November 2020, the technology has been operating effectively to fully achieve the expected results.
