Title:
CALIBRATION METHOD BASED ON PHYSICAL CHARACTERISTICS OF SENSOR
Document Type and Number:
WIPO Patent Application WO/2023/045214
Kind Code:
A1
Abstract:
The invention discloses a sensor calibration method. A lot of sensors are tested before production to obtain the summary pair-data set, classify and divide the summary pair-data set to obtain the typical pair-data sets, and store them in the computer. During production, test small number of pair-data of sensors to be delivered, input the small number of pair-data into the computer, and obtain the closest typical pair-data set to the small number of pair-data and difference between them through calculation, and then adjust the closest typical pair-data set based on the difference, and the adjusted typical data set can be used as the predetermined pair-data of the sensor to be delivered, and the preset predetermined calibration function is no longer needed, which improves the calibration efficiency of the sensor, reduces the production time, and reduces the difference between the actual sensitivity of the sensor and the predetermined pair-data caused by the difference of the physical characteristics of the sensor, and improves the reliability of the sensor.
