| 当前试飞测试系统压力参数的校准主要采取拆卸后在实验室校准的方式，存在校准时间长，多次拆装容易造成接口损坏的问题。为了解决这个问题，研究一种压力参数的在线校准方法，实现了真实工况下的原位比对校准。通过实验获得了标准压力传感器在温度复合情况下的量值特性规律，构建了温度补偿模型，实现了标准压力值的准确获取。研制了由三个不同量程标准压力传感器、环境温湿度和大气压传感器以及在线校准软件等组成的校准装置，通过初步实验验证了校准方法和装置的合理性。该方法可以作为实验室校准的有效补充，降低校准的人力和时间成本，提高飞行试验的效率。 |

| The current calibration method of pressure parameters of a flight test system is laboratory calibration, which is time-consuming and has the problem that multiple dismounting operations may damage the sensor's interface. In this paper, a field calibration method of pressure parameters is studied, and the in-situ comparison calibration is realized under real working conditions. The characteristic of the magnitude of the standard pressure sensor under the condition of temperature compounding is obtained through experiments, and the temperature compensation model is constructed to realize the accurate acquisition of the standard pressure value. A calibration device consisting of three standard pressure sensors with different ranges, ambient temperature, humidity and atmospheric pressure sensors, and field calibration software was developed. The rationality of the calibration method and device was verified through preliminary experiments. This method can be used as an effective supplement to laboratory calibration, reducing the labor and time cost of calibration and improving the efficiency of flight tests. |
