The Single-chip Microcomputer Changing in single a machine combination the machine of frequency realizes water supply system the full-automatic the eternal that turn presses the control, making provide the system of water have the better economy energy, regulating the speed quick.The dynamic function is good.The function waits characteristics more, this is also a high project in price in current function.Adoption AT89C51 single a machine is match that core, pressing in general use mold a design for turning can apply every kind of type changes the machine of frequency and pump set.This design analyzes to change in detail the frequency eternal presses the water supply control system wins election to choose three set water pump work way and processes that hour cut over mutually.And according to AT89C51 the single a machine is for controls the core, making use of its have an 4k EEPROM, but need not outside expand EEPROM, can also simplify to the importation electric circuit, output the electric circuit, manifestation electric circuit, watchdog, and the D/ A converts the hardware of the electric circuit installs.Design that apply the software, adopt the advanced PID faintness control calculate way, and to the A/ D of the system, the D/A of conversion electric circuit, manifestation electric circuit, watchdog electric circuit proceeds the C language with edit collected materials the phonetic procedure design.According to the single a machine changes the design that eternal press water supply control system in threw in physically circulate behind result goodly, text and give the total diagram in a control for system with the procedure flow chart. Key Words: Misty control、The Single-chip Microcomputer、 the frequency machine eternal presses the water supply、 PID 、work frequency charged barbed wire net 、changes the frequency charged barbed wire net、software、hardware。 目 录 摘 要 Abstract 第1章 概 述 1
