摘　　要：飞行参数记录系统是一种用于监测飞机及其系统工作状态以及飞行员操纵飞机情况的机载设备。但由于缺少储能供电设计,不具备延时记录功能,当供电电源中断时,导致飞参系统数据停漏记;为了解决这种数据停漏记的问题,文中从系统供电延时、改进电源监控电路的角度提供了一种可行的新方法,改进电源监控电路设置,同时增加储能供电电路系统,从而有效解决了某型飞参系统数据停漏记问题,保证了数据记录的完整性;该方法在实际工作中得到了应用,具有一定的实用性和推广价值。flight data recorder is a kind of airborne equipment,which is used to monitoring the active states of aircraft systems and the pilot＇s operation. Lack of an energy storage system and record time-delay,data halt or leak in flight data recorder happens when power supply is interrupted. A new feasible method on energy storage for power supply and improving the circuit of power monitor is provided to solve this problem. The circuit of power monitor is improved as well as an energy storage system for power supply is added,which provide a solution to the data halt or leak of the flight data recorder and assure the data integrality. This method has been applied to one type of flight data recorder, and proved to be practicability and generalizing value.
