    • A system for monitoring pressure change within at least one compartment of an aircraft is provided. The system includes a primary pressure sensor for providing a signal corresponding to a pressure within a primary compartment of the aircraft, a primary monitoring channel coupled to the primary pressure sensor, and an output driver coupled to the primary monitoring channel. The primary monitoring channel includes a band pass filter for receiving and filtering the primary pressure signal, a pressure change circuit for determining a change in the filtered pressure signal and for providing a pressure change output signal corresponding to the change in pressure, and a threshold logic circuit for determining whether the pressure change output signal meets a predetermined threshold and for providing a threshold output signal indicating that a decompression event has occurred if the pressure change output signal meets the predetermined threshold. The output driver receives the primary threshold output signal and outputs a notification signal.
    • 提供了一种用于在飞行器的至少一个隔间内监测压力变化的系统。 该系统包括主压力传感器,用于提供对应于飞行器的主舱内的压力的信号,耦合到主压力传感器的主监控通道以及耦合到主监控通道的输出驱动器。 主监视通道包括用于接收和过滤主压力信号的带通滤波器,用于确定滤波压力信号变化并提供与压力变化相对应的压力变化输出信号的压力变化电路,以及阈值逻辑 电路,用于确定压力变化输出信号是否满足预定阈值,以及如果压力变化输出信号满足预定阈值,则提供指示减压事件已经发生的阈值输出信号。 输出驱动器接收主阈值输出信号并输出​​通知信号。
