When the infrared temperature sensor is used specifically, the infrared temperature sensor is adopted to detect the temperature in the drying chamber, and the radiation heat effect is utilized, so that the infrared temperature sensor has the characteristics of high sensitivity and high signal-to-noise ratio.

The triode VT1 forms an emitter follower at the output end of the operational amplifier U1 to follow and amplify the detection signal, thereby greatly improving the signal processing efficiency; simultaneously, inductance L1 and electric capacity C2 form LC parallel resonance and carry out the frequency selection to infrared temperature detection signal to restrain external clutter interference well, promote temperature detection signal processing accuracy.
An operational amplifier U2 in the isolation stabilizing circuit utilizes the voltage follower principle to carry out isolation output on an output signal of the filtering amplifying circuit, thereby avoiding the influence of electric interference of a preceding-stage circuit, compensating the signal by a capacitor C4 and ensuring the continuous and stable output of the signal; then, the capacitor C5 and the resistor R6 form RC filtering to improve the waveform of the output signal of the operational amplifier U2, and the improved waveform is sent to the controller. And after the temperature signal input end of the controller receives the detection signal, the internal analysis processing is carried out on the detection signal, and a real-time temperature value is calculated.
