  • Aiming at the fluctuation of the pot bottom temperature measurement value caused by factors such as flame instability, an adaptive algorithm for temperature measurement of infrared sensor was proposed.By taking weighted average of the historical temperature samples and selecting the appropriate temperature sampling frequency and adaptive system parameters, the algorithm could effectively filter the stochastic temperature drift of the single temperature sample and solve the overheating signal judgement interval increasing caused by the temperature fluctuation so as to improve the sensitivity of overheating signal.Experimental results showed that the proposed algorithm could detect the overheating signal within 5 s,and the complexity of the algorithm was reduced to O(1).
