Abstract
In the thesis, the disadvantages and problems need to be resolved of current supporting water system are briefly analyzed, and a new system, which has great advance in automation, reliability and saving energy, is studied and described.
This thesis consists of five chapters.Chapter one clarifies the application background and significance of the supporting water system and main contents of research. Chapter two introduces the overall project of the new auto-control system, including craft demand, constitution, work principle and the selection of the main electrical devices.Chapter three emphasizes the principle of the software and hardware part in control system. Chapter four, we analyze the exploitation of control system, specifying on PLC programmer and introduces the principle, parameter installation of PID control. The last chapter is the conclusion of the whole research and presents some debug result.
The research collectively utilized some modern control devices, such as PLC, frequency conversion device, sensor, and their program control method, all of these are of some reference value to the study of relative control system.
