The invention relates to the technical field of aircraft environment control, in particular to a pneumatic type cabin pressure adjusting system fault diagnosis method. A fault diagnosis logic is established by researching a cabin pressure regulating system fault mode and a historical database, extracting feature data, specifying a feature data threshold value, and when onboard detection data exceeds the threshold value, a fault part is judged according to the fault diagnosis logic. After the aircraft cockpit pressure regulating system breaks down, a user can quickly judge the fault reason and accurately isolate the fault position, the problem that the cockpit pressure regulator returns to a factory without faults due to the fact that the fault of a client is difficult to locate is solved, and therefore the troubleshooting efficiency of an aircraft system is improved, and the troubleshooting period is shortened.
本发明涉及飞机环境控制技术领域,涉及一种气动式座舱压力调节系统故障诊断方法。通过研究座舱压力调节系统故障模式、历史数据库,提取特征数据,规定特征数据阈值,建立故障诊断逻辑,当机上检测数据超出阈值时,依据故障诊断逻辑,判断故障部位。飞机座舱压力调节系统出现故障后,用户可以快速判断故障原因,准确隔离故障部位,解决客户故障定位困难而造成座舱压力调节器无故障返厂问题,从而提升飞机系统排故效率,缩短排故周期。
