Intelligent Precision Water Pressure Generator Developed

Intelligent precise water pressure controller is an important instrument of generating and controlling water pressure. It can replace the normal source of water pressure; It can generate dynamic water pressure which have different frequency and different range; It also can be set to generate static water pressure. To satisfy this kind of practical demand, this Master's degree paper expatiates the basic theories and knowledge in designing the instrument that generate water pressure, which developed in the corresponding research subject. Details are provided at some key points.The MCU AT89C52 is used as a core component in this system. With the help of software programmed in C language, the system drives electromotor to execute relevant work after disposing and calculating each electric signal, and the controller becomes a closed loop system. It can deal with exigency when there is something wrong in this working system. Communications and PC controlling are also discussed in this paper, and certain research has been done. The PC software of this intelligent controller is programmed by Visual Basic language: It can send command signal to MCU and can receive and display the water pressure signal from MCU, so the system' s working state can be watched more easily; At the same time , It can analyze and save the data automatically. So the whole control system becomes more digital and more intelligent.The debugging and running of the system indicate that the whole design is feasible and reliable, and the presumed functions have been conducted successfully.
