Research And Development On Control Systems For Water Supply With Constant Hydraulic Pressure

With the development of science and technology, Single-Chip Microcomputer (SCM) has been used widely, which greatly promotes the renovation of traditional control technology. Current research on the constant hydraulic pressure water supply control system has their own advantages. With the development of microchip and frequency conversion technology, the new generation of constant hydraulic pressure water supply system should have the excellence of simple equipment, less investment, higher reliability, stronger anti-jamming ability, higher efficiency and energy saving.Basing the current research on Single-chip computer controlled constant hydraulic pressure control system, using the news, advanced components, and designed pumping systems - constant hydraulic pressure water tank intelligent control system. The system has high reliability, strong anti-jamming ability, higher efficiency and energy saving.First introduce the preamble of the system and the development of key components of the system, such as the performance of it. In the second chapter, we compare several typical compositions of the constant hydraulic pressure water supply system on the advantage and disadvantaged of each system. The merits of the case and the feasibility are summed.In the third chapter discussed the system components and system works of the case. In the system components, the system block diagram and control schematics are given, and make a brief introduction on main function of hardware and software of the system.In the fourth chapter, described the design on the hardware of the system, studied the control system on the overall hardware structure, and established various parts of the functions of hardware modules, and gives some typical circuit; make choices of components , and introduced the functions and detailed presentation on various chips used in the system. Studied the hardware Circuit design and given the structure of it. Studied the main program modules,alarm detection module and water pump control module.In chapter five developed the main program and control subroutine's workflow for software design.Finally, Chapter six on the water supply system was summarized.
