| Abstract: | The system takes the AT89C52 single chip as its controlling core.Its hardware mainly consists of two parts.The single digital temperature sensor DS18B20 constitutes a pre-signal acquisition circuit,while the back controlling circuit is mainly composed of the crossing zero testing photoelectric coupling unit MOC3041 which is made up of silicon availably controlled both in two directions.The system uses a controlling arithmetic that is called PID in different segment,and it uses the adjusting power method to ... |
