The invention discloses an algorithm for stabilizing the temperature test value of a temperature sensor. By adding a calculation step to the basic algorithm of the existing temperature sensor, the approach value of the self-variance of the temperature sensor to the temperature detection is used, and the current measurement The calculated variance of a set of data acquired by the temperature data, the actual fluctuation amplitude of the temperature sensor for temperature measurement and the measurement gain of the temperature measurement are obtained comprehensively, according to the formula A=N+G*(N‑M) After a corrected test data value, the actual value of the temperature is obtained according to the data value combined with the gain coefficient and the debuff coefficient of the temperature sensor itself; in addition, a system for stabilizing the temperature test value of the temperature sensor is provided, combined with the foregoing, the purpose An algorithm and system for stabilizing the temperature test value of a temperature sensor are provided, and the algorithm is used to stabilize the problem of unstable temperature detection of the existing temperature sensor, so as to improve the detection accuracy of the temperature sensor.
Description
technical field [0001] The invention relates to the field of temperature measurement, in particular to an algorithm and a system for stabilizing the temperature test value of a temperature sensor. Background technique [0002] At present, due to the calculation of the temperature of the object in the field of view, it needs to be calculated according to the temperature of the sensor. If the read temperature is deviated, the measured physical temperature in the field of view will be inaccurate, resulting in inaccurate temperature measurement, which can easily lead to False alarms in temperature measurement, resulting in many diagnostic biases. [0003] In addition, due to the influence of communication reasons or the error of the sensor itself, the acquired temperature of the sensor has a relatively large error, which eventually results in inaccurate measurement. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to solve at least one problem existin...
