Calibration of Pressure Sensor Array Based on Information Fusion

摘要

It is existence of cross-sensitivity factors such as the temperature, humidity and power fluctuations in pressure sensor array. To solve this problem, it is proposed an information fusion based on the pressure sensor array calibration algorithm. By this method can effectively eliminate the environmental temperature and voltage disturbances and other non-target parameters, and crosstalk between large-scale sensor array signal output of pressure sensor array characteristics. It is improved system stability and reliability. Experimental results show that the information fusion processing algorithms realize the precise calibration of the pressure sensor array, the effective sensor array measurement data to ensure the accuracy and reliability of the results.
