Background technology
At present, the ATM withdrawal room (withdrawal booth) of bank, in order to protect depositor more safely to withdraw the money, some is each
(the closing protective cabin of similar closing telephone booth) closing protective cabin (room), i.e. one, a cabin is installed outside ATM ATMs
ATM ATMs (abbreviation ATM), ATM protective cabin are provided with hatch door electronic system, carry out " cabin of a people one " (in principle, one
It is secondary to there is a people to enter cabin) management.ATM protection hatch door electronic system typically uses is equipped with enabling inside and outside protective cabin
Button, the outer set door open button of protective cabin are button of entering, and the door open button set by protective cabin is exit button, in order to have
Come out from the inside beneficial to short people, the exit button setting height(from bottom) in cabin is about 1.1 meters.After hatch door closure latches, hatch door
When the human body sensor that electronic system is set in cabin detects someone, the unlocking function for button of entering is shielded, outside
People door can not be opened, it is necessary to the button in operational window could open door, so as to prevent other people trail, protect the inside
People operates the security of ATM.In order to which button of being entered when preventing child to be strayed into and fallen in a swoon (faintness falls down to the ground) with ATM user has
Unlocking function it is effective, only to 1 meter of 2 space above in cabin, whether someone detects setting human body sensor, when 1 meter more than 2
Spatially someone, identification have ATM user, the unblock work(shielding to button of entering, as 1 meter of 2 space above nobody, assert nothing
ATM user or user, which faint, to be fallen down to the ground, and the unlocking function of the button of entering of shielding is discharged.Perfect design is seemed, is really existed
The defects of one very big, setting detect 1 meter of 2 space above whether the human body sensor of someone, due to shadows such as temperature, agings
Ring, can cause to extend downwardly the spatial altitude of detection for 1 meter 2, numerous media are reported often:Because by between 1 to 1 meter 2 of height 1 meter
Child's false-lock can not open hatch door in ATM protective cabin, the people of outside because human body sensor detect people assert cabin
Inside there is ATM user.This defect causes:When only stopping child in protective cabin, child will be unable to walk out protective cabin.

People in cabin, which faints to fall down to the ground, detects identification, that is, human body sensor is in three times alternation processes of pattern two and pattern
When at middle human body sensor work in mode three, the detection identification that falls down to the ground of just being fainted to the people in cabin;
3) when human body sensor reaches two alternating weeks in the Time Continuous of three times alternations of pattern two and pattern
Phase, and only have human body sensor work when detecting human body in mode three within this continuous two cycle, then assert cabin
Inside there is child to be stranded, the hatch door of locking is unlocked, and have child stranded to be gone out by being located in loudspeaker output cabin out of my cabin
Voice help-asking information, otherwise, assert to be stranded without child in cabin and treat out;
4) when human body sensor work in mode three, no matter detection recognizes the voice signal amplitude size of input
How, if it is to be detected less than human body when, assert that the people in cabin faints and fall down to the ground stranded, the hatch door of locking is unlocked, and by setting
The voice help-asking information that someone's faintness falls down to the ground in loudspeaker output cabin out of my cabin, otherwise, assert that the people in cabin does not have faintness to fall
Ground;
S40, when unlocking hatch door, and stop ongoing people and faint to fall down to the ground and the stranded detection identification of child.
The above-described voice help-asking information exported by the loudspeaker being located at out of my cabin, when hatch door is opened, loudspeaker
Stop output voice help-asking information.
The above-described beginning T1 seconds prescribe a time limit, and its T1 second is arranged to 3 seconds.
Above-described control human body sensor is switched to the three times alternations of pattern two and pattern, during alternation
Between be arranged to the T2 seconds, that is to say, that the cycle of three times alternations of pattern two and pattern is 2 T2 seconds, that is, control human body sensing pass
Sensor is switched to human body sensor after two times work T2 seconds of pattern and worked in mode three the T2 seconds, is then switched to people again
Body induction sensor in the work T2 seconds of pattern two times, the like, in the present invention T2 seconds of alternation time be arranged to 3 seconds,
Then human body sensor is 6 seconds in three times alternation cycles of pattern two and pattern.
Above-described threshold value refers to:The input sound preserved is detected by sound input circuit when the loudness of sound is 40db
Sound signal amplitude.
Above-described human body sensor reaches two in the Time Continuous of three times alternations of pattern two and pattern
Alternate cycle, the voice signal amplitude that input is recognized equivalent to continuous detection reach human body sensing more than the time of given threshold
Sensor is in two alternate cycle times of three times alternations of pattern two and pattern, that is, continuous detection recognizes input
Voice signal amplitude be more than time of given threshold and reach 4 T2 seconds, the present invention is 12 seconds.
Above method is hatch door electronic system with being carried out under remote control off-line state.
