本设计采用无ROM的8051作为主控制芯片。8051的接口电路有8155,2732和ADC0809等芯片。8155用于键盘/LED显示器接口,2732可作为8031的外部ROM存储器,ADC0809为温度测量电路的输入接口。
本设计温度控制电路是通过可控硅调功器实现的。双向可控硅管和加热丝串联接在交流220V,50HZ交流市电回路,在给定周期内,8031只要改变可控硅管的接通时间便可改变加热丝功率,以达到调节温度的目的。
-This design uses no ROM 8051 as the main control chip. The interface circuit 8051 8155,2732 and ADC0809 and other chips. 8155 for the keyboard/LED display interface 2732 can be used as an external ROM memory 8031, ADC0809 for the temperature measurement circuit input. The temperature control circuit is designed by SCR Power Regulator to achieve. Triac tube and heating wire connected in series in the AC 220V, 50HZ AC power circuit, in a given period, as long as the change in SCR 8031 on-time control of the power of heating wire can be changed in order to achieve the purpose of regulating the temperature .
