The technical solution adopted for the present invention to solve the technical problems is：
The constant control device of far infrared therapeutic apparatus radiation assembly radiation wavelength, intensity, including far infrared therapeutic apparatus single-chip microcomputer with
Solid-state zero passage relay, far infrared radiation component is provided with thermocouple, and thermocouple connects with the input of far infrared therapeutic apparatus single-chip microcomputer
Mouth is connected, and far infrared therapeutic apparatus single-chip microcomputer was the triggering of a cycle output pwm signal control solid-state zero passage relay with 2 seconds
End, AC power is applied on far infrared radiation component；Far infrared therapeutic apparatus single-chip microcomputer read a thermocouple every 0.2 second
Temperature, calculate the temperature averages T2 of far infrared radiation component by storage of array, far infrared therapeutic apparatus single-chip microcomputer is calculated
The temperature gap err of the desired temperature T1 and temperature averages T2 of far infrared radiation component operation；
If err is more than max-thresholds T3, pwm signal is maximum duty cycle signal, makes solid-state zero passage relay total power defeated
Go out；
If err is less than minimum threshold T4, pwm signal is closed, cut off solid-state relay power output；
If T4<err<T3, then with dutycycle tempctrl output pwm signals, tempctrl is according to formula
Calculate：
tempctrl = tempctrl 1+ add；
add= KP*(err - err1) + KI*err + KD*(err - 2*err1 + err2)；
