The invention aims to provide an air tightness detection system and method for aircraft equipment, the system comprises a control terminal and a data acquisition terminal, and the control terminal comprises a data receiving module, a sensor metering module and a plurality of air tightness detection modules; the air tightness detection module is used for outputting a pressure control signal to the electronic pressure regulator EPC to realize air tightness detection; and the sensor metering module is used for acquiring and correcting the taste correction coefficient of the feedback data and correcting the collected feedback data by adopting the taste correction coefficient. The taste correction coefficient comprises a deviation constant pb and a deviation coefficient pk. The control terminal outputs a pressure control signal to the electronic pressure regulator EPC, collects feedback signals of the electronic pressure regulator EPC, the pressure sensor P and the flowmeter L at the same time, and corrects collected data in real time, so that the reliability of airtight detection of the aircraft equipment is well guaranteed, and good practicability is achieved.

    本发明的目的在于提供一种用于飞机设备的气密检测系统及方法,所述系统包括控制终端、数据采集终端,所述控制终端包括数据接收模块、传感器计量模块以及若干个气密检测模块;所述气密检测模块用于向电子压力调节器EPC输出压力控制信号实现气密检测;所述传感器计量模块用于获取、修正反馈数据的校尝系数以及采用校尝系数修正采集的反馈数据。所述校尝系数包括偏离常数pb和偏离系数pk。所述控制终端向电子压力调节器EPC输出压力控制信号,同时采集电子压力调节器EPC、压力传感器P、流量计L的反馈信号,实时校正采集的数据,较好的保证了飞机设备气密检测的可靠性,具有较好的实用性。
