Water Treatmen Process Control Software Design And Implementation

The problem of lacking water is restricted in its economic development for the bottleneck. The World is widely concerned due to water treatment and water recycling. However, monitoring technology of sewage treatment in China was carried out lately. Meanwhile, the monitoring systems and equipments of water treatment process have to be imported from abroad. Our governments at various levels have also put large amounts of funds into the monitoring systems and equipments of water treatment.MEMS Center, Harbin Institute of Technology for the sewage treatment plants develop to sewage treatment process real-time monitoring system. The system includes monitoring software system and hardware platform. My main task is to prepare for the applications software system of water monitoring system monitoring system. The applications software framework consists of three tiers: Client application, Server application and databases.The design of Monitoring software was realized by using modularized software design method, which achieve the objective of remote system maintenance and upgrade. At first, the dominant module of client application: process interface module; logs, user and device management module; user Login. Design of client based on completion, to achieve beautiful, clear, and user-friendly client interaction. The application server module include: communication module, automatic control, log module, etc. MINA techniques developed for communication module; Hibernate middleware use in database operations; the PID control algorithm for maintaining the dissolved oxygen concentration for automatic control module. According to the development of client and server, establish 10 table structures in the database.Accomplished the debugging and testing, the software runs properly. The result demonstrated that the demand of the monitoring supervision software was realized.
