Amplified the circuit and offered the temperature signal by PT1000 and voltage, realize through PID algorithm that controls the power and temperature of electric stove , use SSR solid state relay to carry out the part , make the static error of the system reduce to minimumly . This design has also fully utilized a slice of ripe pronunciation treatment technology of SPCE061A form (have higher processing speeds, can deal with more complicated digital signal fast ) graph processing function of and the PC , to realize the pronunciation report temperature and type the demand for changing the curve of temperature. The content of the full text includes mainly: The hardware system of the control system of the temperature is designed, the software system is designed, the characteristic , performance , structure , development , application , order parameter and pronunciation treatment technology of SPCE061A one-chip computer. Keywords SPCE061A one-chip computer; Pt1000; PID; 引 言 自70年代以来，由于工业过程控制的需要，特别是在微电子技术和计算机技术的迅猛发展，以及自动控制理论和设计方法发展的推动下，国外温度控制系统发展迅速，并在智能化自适应参数自整定等方面取得成果。在这方面以日本、美国、德国、瑞典等国技术领先，并且都
