Airtightness detection method and related device

Abstract

The application discloses a kind of airtightness detection method and related equipment, the method comprises: control inflation device is carried out N times inflation processing to test cavity, the inflation amount of first inflation processing is determined according to the gas amount that can make the air pressure of test cavity reach target air pressure, test cavity is equipped with measured object and air pressure sensor, N is the integer greater than 1;N parts of sensor data corresponding to N times inflation processing are acquired by air pressure sensor acquisition;Based on target air pressure and the sensor data corresponding to first inflation processing, N parts of sensor data are adjusted, obtain N parts of first sensor data;Based on the control information of N times inflation processing respectively, and N parts of first sensor data, determine N parts of second sensor data;At least based on the inflation amount of N times inflation processing respectively, and N parts of second sensor data, determine the airtightness detection result of measured object, so, it can improve airtightness detection precision.
