中文摘要:压力传感器作为民机环控系统中的关重成品件,其性能好坏直接影响飞机空气系统的管理。为保证其装机质量,提升飞机研制和批产效率,设计了一套压力传感器自动测试台,用于压力传感器的性能测试。首先介绍了压力传感器在机上的功能、分类以及性能参数;然后根据其测试特性,分别从硬件构架、设备选型、测试软件以及配套设备等四个方面阐述了压力传感器测试台的设计方案,实现通过测试软件对压力传感器测试压力和温度的自动控制,并在测试压力和温度达到稳定后,自动采集压力传感器输出的电压信号,经过数据处理后生成测试报告并判断测试结果;最后列出了压力传感器测试台的应用范围和意义。
英文摘要:As a key and important component in the environmental control system of civil aircraft, the performance of pressure sensor affects directly the management of aircraft air system.In order to ensure the quality of its installation and to improve the efficiency of aircraft development and batch production, an automatic pressure sensor test bench was designed for the performance test of pressure sensor. Firstly, this paper introduces the function,classification and performance parameters of the pressure sensor on the machine. Then, according to the test characteristics, the design scheme of the pressure sensor testing platform was elaborated from four aspects of test hardware architecture,equipment selection,test software and supporting equipment. Through the test software, we realized the automatic control of the pressure and temperature of the pressure sensor; after the test pressure and temperature stabilizing, the voltage signal of the pressure sensor was collected automatically; the test report was generated and judged after data processing. Finally, the application scope and significance of the pressure sensor test bench were presented.
