2) set the interval input audio signal amplitude less than the T3 second that recognizes to be detected during voice response more than setting threshold value
Time persistently reaches the T4 second, and all can recognize human body sensor within T4 time second that this is lasting when human body being detected,
There is child stranded in assert cabin, the hatch door of locking is unlocked, and child is stranded to be treated by having in being located at speaker output cabin out of my cabin
The voice help-asking information gone out, otherwise, treats out without child is stranded in assert cabin;
S40, time hatch door is unlocked, stop ongoing people and faint and fall down to the ground and the stranded detection of child identifies, and hang up the sound of release
Tone signal amplitude detection identification function.
The voice help-asking information of the above-described speaker output by being located at out of my cabin, when hatch door is opened, speaker stops defeated
Go out voice help-asking information.
The above-described T1 second is set to 3 seconds;The described T2 second is set to 3 seconds;The described T3 second is set to 2 seconds;Described
The T4 second be set to 20 seconds.
The above-described threshold value that sets refers to: sound intensity is believed as the input sound preserved by the detection of sound input circuit during 40db
Number amplitude.
Above-described detection recognizes interval and lasts up to more than the time setting threshold value less than the input audio signal amplitude of T3 second
To the T4 second, refer to: detection recognizes sound interval and is less than the T3 second, and this interval is less than the acoustical signal amplitude of T3 second more than setting
Determine threshold value, and the persistent period continuously reaches the T4 second.
It is above-described that " interval that recognizes to be detected continues more than the time setting threshold value less than the input audio signal amplitude of T3 second
Reach the T4 second, and within T4 time second that this is lasting, all can recognize human body sensor human body detected " in " and at this
All can recognize human body sensor in lasting T4 time second and human body be detected " refer to: the interval that detection recognizes is less than
The input audio signal amplitude of T3 second is more than all recognizing human body sensor inspection in lasting T4 time second setting threshold value
Measure human body.
Above method is that hatch door electronic system is carried out under remotely control off-line state.
