Be on/off circuit of the present invention as shown in Figure 1, the operation principle of this circuit specifically describes as follows:
Steps A, user presses after switching on and shutting down button, and on-off circuit unit produces triggering signal low level and sends into on/off circuit, and this effective triggering signal is sent into through time delay, after anti-phase or the first input end of door chip, or effectively input of door chip acquisition, produce high level and effectively export.
Step B, due to the control end of analog switch with or the output of door chip be connected, the control end of analog switch is obtaining after high level enable signal, in closure state, switching on and shutting down managing chip obtains operating voltage, on/off circuit is started working; Meanwhile, the Circuits System of EMBEDDED AVIONICS also obtains system works voltage.
Step C, because user presses the time delay that switching on and shutting down button duration exceedes delay circuit, the triggering signal low level of on-off circuit unit output remains valid, make the first input end of switching on and shutting down managing chip obtain effective triggering signal, and then the output of switching on and shutting down managing chip produces high level systems starting-up signal, send into or the second input of door chip and the Circuits System of EMBEDDED AVIONICS device power-up.
Step D, after trip switch machine button, on-off circuit unit is output as high-impedance state, delay, or a door chip first input end is disarmed state when process; But now, due to system boot signal be high level useful signal send into or door chip the second input, so or door chip output be still high level useful signal, analog switch is in closure state, the operating voltage of switching on and shutting down managing chip remains unchanged, and on/off circuit is normally worked.
Step e, under on/off circuit normal operating conditions, switching on and shutting down button is pressed, and on-off circuit unit produces low level triggering signal, it is low level system closedown signal that switching on and shutting down managing chip changes its output signal, this signal be invalid signals send into or door chip the second input; Due to the effect of delay circuit, within definite time delay time of delay circuit, delay circuit output signal is in low level, or door chip first input end becomes disarmed state, and then or the output of door chip produce low level invalid signals, cause analog switch to disconnect, make the switching on and shutting down managing chip voltage of losing the job, on/off circuit quits work, and equipment shutdown power consumption is zero.
