Pb - Zn Mine Water Supply Intelligent Monitoring System,

With the improvement of the people's living level, the requirement of the water quality becomes stricter. So the problem of the water process in the water factory appears. How to improve the automation of the water process is an urgent problem.The water source of FanKou mine's water supply is provided by the GaoPing reservoir of the RenHua county. The water quality affected by entironment heavily because the distant of the water source is too far and the transportation aqueduct of the water is open channel. In the common situation, the water from the reservoir is weak acidic. But in the rain day, the water turbidity and the acidic will increase. In addition, the water in the reservoir will be worse because of the pollution of the outside environment. It needs add medicament to depositing, disinfecting and balancing the acidity and the alkali of the water so that it accord with the standard of the water quality in our country.The water processing of FanKou mine was manual work in the past: detect the turbidity and make the impurity deposition; detect the PH value and add Na2CO3 to adjusting the acidity and the alkali; add ClO2 to disinfecting. In our country, the quantity of the water-processing medicament has clear prescript: the quantity of the remaining chlorine must less than 0.2ppm. If the remaining chlorine in the processed water exceeds the standard, it not only will affect the health of people but also will rot the channel.Based on the above depiction, in this paper, we using the characters of the fuzzy control to design two 2-inputs and 1-output systems aim at the turbidity and the quantity of the remaining chlorine in the water. The characters of fuzzy control are: it needn't clear mathematics model; it can get better result for the nonlinear and pure time-delay system. In the end of the paper, we compare the fuzzy system and the PID system according to the simulation. It shows that the design of the fuzzy system is success. Both the dynamic performance and the static parameters are improved largely. Based on the research the paper also describes a monitoring and controlling computer system for water process. The key factors of the software development, including the framework, function design, platform selecting and some chief programming technologies, are introduced. The practical application of the system can prove its effectiveness by higher operation accuracy, less human labor and cleaner output water. The efficiency and quality of water process can be improved and the level of automation and information of water supply can be promoted.
