This design topic is based on 51 monolithic integrated circuitstemperature observation and control systems. Using 8,051 monolithicintegrated circuits is the microprocessor, carries on the comparisonto the temperature automatic sampling examination and with the givenvalue, uses the fuzzy PID control thought to carry on the control tothe temperature. Uses the monolithic integrated circuit fuzzy controlsystem control temperature to be able to overcome the temperatureobject well the pure lag characteristic, the control response timeshort, the over modulation small also the system structure simple, theapplicable scope is broad. The design hardware electric circuit by the MCS-51 series in 8,051took the system the core, use intelligence temperature sensor DS18B20is the feeling warm part. This kind of single main line, the digitaltemperature sensor applied to the computer and the automatedobservation and control domain changed the traditional temperaturetest method, directly transmitted the temperature physical quantitytransformation for the digital signal and by the main line way to thecomputer carries on the data processing. Then through the zerodetector set, the temperature control installment carries on heats upachieved carries on the control to the temperature the goal. Outside8051 meets serial EEPROM24C16, the monitor, the keyboard, 看门狗the electric circuit, with independent electric power supply.Simultaneously the systematic each part all useful specific componentsharpens its antijamming ability. Software designs the content carries on the compilation using themonolithic integrated circuit assembly language. The main contentincludes: Master routine, keyboard demonstration procedure, T0interrupt routine, sampling procedure, digital filter procedure, scaletransformation procedure, PID running program, T1 interrupt routine,看门狗 procedure. This design main design content is the hardware electric circuitdesign, the component choice and the connection, the software flow,carries on the schematic diagram using PROTEL the plan. Grasps thesystem the principle of work, the antijamming design which between thehardware electric circuit various components connects. Carries on thecomprehensive understanding to each chip attached primary devicefunction, completes its and the chip connection and the positiondesign. This experimental partial components applied skidded therheostat to carry on adjust zero, in order to increased the accuracy.
