The Development Of Water Consumption Monitoring And Management Decision System Based On The Industrial Ethernet

This thesis, with the name of "The water consumption monitoring and the management decision system based on the industrial Ethernet" (No: 20100819-1), is the declaring project of Jincheng Anthracite Mining Group. It is proposed on the shortage of water resources in our country, and serious waste and poor management of water resources in Sihe Mine. A set of system which monitors and manages the water consuming in enterprises automatically has been developed according to the distribution of pipe network and the management requirement of Sihe Mine. It collects microprocessor technology, network technology, sensor technology and wavelet analysis technology in one body which could raise water resource efficiently and improve water management situation in medium and large scale industrial enterprises.Medium and large scale industrial enterprises consider a department as the water consumption accounting unit. But all the costs undertake by the enterprises. Water-saving responsibility of each department is not clear. Each department has no strong consciousness of saving water. All those lead to the huge waste of water in medium and large scale industrial enterprises and increasing enterprises and society’s economic burden. Therefore, this developed system in this paper uses the high-accuracy sensor, develops the monitoring station with PLC as the core. It also develops the monitoring software based on B/S Structure and sets up Wireless Ethernet. The diagnosis software of tube-bursting accidents in water supply network is developed based wavelet analysis in this system.The system has been put in service in July 2011. The main research contents of this thesis are as follows:This paper gives out the whole project design and proposes function indicators of the system based on the reference of literature with deep analysis of the requirement of management about water consuming and the trend of the system about water flux monitor and manager. It constructs the software and hardware frame structure of the system combined with microprocessor technology, network technology, sensor technology and so on. Using network as bridge, framework is a three-architecture. Three tiered network architecture based on wireless is established, which composes of first-level monitor centre and second-level monitor centre.Based on the condition of pipe network, we choose and test the sensor’s type and feature. The water consumption monitoring and the management decision system based on PLC are designed with the requirements of high accuracy and strong anti-jamming capability. Monitoring and remote transmission of flow rate and pressure is realized. Pressure, instantaneous flow rate and cumulative flow rate subprogram with high portability is developed by using modular programming methods.Using open network architecture and Kingview 6.55WEB as software flat in monitoring center, a set of analysis decision system based on B/S structure is developed, which can realize the function of real-time monitoring, alarming and information collecting. The "characteristic energy-Fault Identification" warning strategy is proposed, which can analyze fault of pipe network, locate the position of pipe explosion. Configuration man-machine interface has the merits such as strong interaction, simple and beautiful screen and perfect functions.Wireless industrial Ethernet is used as the communication protocol in this thesis. A dual-star network topology is designed on the basis of fieldwork of network installation environment. Dual-star network topology is designed by using the MOXA wireless AP. Seamless information integration between management layer and field control layer is completed. Meanwhile, the connection between the PLC monitoring LAN and the group network is cut off, which improve security of the PLC monitoring LAN, and save public IP resources of the company.Tested by the hardware and software system in the laboratory, this system could meet the expectations index; Adjusted in the lab, this system has completed the installation and debugging. The system has been successfully running in Sihe coal mine for water consumption monitoring and the management decision system in July 2011, and the debugging and operation results show that:The system hardware has a perfect function with a compact structure and stable performance; the software program operate precision; analysis and decision-making software interface is fully functional and operable. Communication network has the characteristics of strong real-time, no dropping packets phenomenon. The whole system could meet the design requirements.
