某型飞控计算机与地面检测设备无法连接故障分析

Failure Analysis of a Flight Control Computer Unable to Connect with Ground Detection Equipment

某型飞控计算机作为飞机飞控系统的主要控制部件,负责将飞行人员的操作指令、作动器位置传感器、速率陀螺、空气动静压、加速度计等信号进行转化、分析[1],最终形成控制飞机姿态变化的控制率。当飞机报故不能清除时,采用地面检测设备对飞机进行检测,如果飞机发生与地面检测设备的连接故障,将导致飞机故障检测无法进行,严重影响产品的检测和故障排除的周期。因此,论文对飞机与地面检测设备连接故障进行分析,具有重要意义。

As the main control part of aircraft flight control system, a certain type of flight control computer is responsible for transforming and analyzing the signals of pilots' operation instructions, actuator position sensors, rate gyroscopes, aerostatic pressure, accelerometers, etc.[1], and finally forming the control rate of controlling aircraft attitude change. When the aircraft accident can not be cleared, the ground detection equipment is used to detect the aircraft. If the connecting fault between the aircraft and the ground detection equipment occurs, it will lead to the failure detection of the aircraft, which will seriously affect the cycle of product detection and troubleshooting. Therefore, it is of great significance to analyze the connecting fault between the aircraft and the ground detection equipment.
