    • A system checks the operability of electrical-based components (10, 14, 17, 19) in a breathing equipment (16), such as a Self-Contained Breathing Apparatus (SCAB), for example. The system includes a microprocessor (7) which is communicatively coupled with the electrical-based components (10, 14, 17, 19). After a power-up of the breathing equipment, the microprocessor (7) receives a signal from the electrical-based components (10, 14, 17, 19) indicating the operational state of that particular component. If the signal is not received by the microprocessor (7), or the signal deviates from a predetermined threshold, then that electrical-based component (10, 14, 17, 19) has failed to function properly. In that case, a visual indication of the failure is provided to a user of the breathing equipment (16). In addition, the system provides a visual identification of whether the microprocessor (7) itself is malfunctioning. A method is also provided for checking the operability of electrical-based components (10, 14, 17, 19) in the breathing equipment (16).
    • 例如,系统检查呼吸设备(16)中的电气部件(10,14,17,19)的可操作性,例如自给式呼吸装置(SCAB)。 该系统包括与电气元件(10,14,17,19)通信地耦合的微处理器(7)。 在呼吸设备通电之后,微处理器(7)接收来自指示该特定组件的操作状态的基于电的组件(10,14,17,19)的信号。 如果微处理器(7)没有接收到信号,或者信号偏离预定的阈值,则该电气部件(10,14,17,19)未能正常工作。 在这种情况下,向呼吸设备(16)的用户提供故障的视觉指示。 此外,该系统提供了微处理器(7)本身是否故障的视觉识别。 还提供了一种用于检查呼吸装置(16)中的电气部件(10,14,17,19)的可操作性的方法。
