Background technology
At present, the ATM of bank is withdrawn the money room (booth of withdrawing the money), in order to protect depositor to withdraw the money more safely, have at each ATM
Being provided with (the similar closing protective cabin closing telephone booth) outside ATM and close protective cabin (room), i.e. one one, cabin ATM is certainly
Dynamic cash dispenser (abbreviation ATM), ATM protective cabin is provided with hatch door electronic system, carries out " people one cabin " (in principle,
Secondary a people can only be had to enter cabin) management.ATM protection hatch door electronic system typically uses and is equipped with enabling inside and outside protective cabin
Button, the outer set door open button of protective cabin tells a button, in order to have button of entering, door open button set in protective cabin
Being beneficial to short people the most out, the button setting height(from bottom) of going out in cabin is about 1.1 meters.After hatch door Guan Bi latches, hatch door
When the human body sensor that electronic system is arranged in cabin has detected people, the unlocking function of button of entering is shielded, outside
Door cannot be opened by people, it is necessary to door could be opened by the button in operational window, thus prevents other people from trailing, and protects the people of the inside
The security of operation ATM.In order to prevent child be strayed into ATM make employment fall in a swoon (faintness falls down to the ground) time enter what button had
Unlocking function is effective, and only in cabin 1 meter of 2 space above, whether someone detects, when 1 meter more than 2 to set human body sensor
Spatially there is people, assert there is ATM user, the unblock merit of button of entering is shielded, as 1 meter of 2 space above nobody, recognizes
Fixed faintness without ATM user or user falls down to the ground, the unlocking function release of button of entering shielding.Seem perfect design, really
There is a defect the biggest, set whether 1 meter of 2 space above of detection has the human body sensor of people, due to temperature, always
The impact such as changing, can cause downwardly extending the spatial altitude of detection for 1 meter 2, numerous media are reported often: because of by height 1 meter 1
Child's false-lock between 1 meter 2 cannot open hatch door ATM protective cabin, the people of outside, because human body sensor inspection
Measure in people assert cabin and have ATM user.The appearance of this defect causes: when only stopping child in protective cabin, child will be unable to
Walk out protective cabin.If human body sensor sensitivity is dropped at the end when arranging, i.e. human body sensor space exploration distance cabin
The height on interior ground is lifted up more than 1 meter 2, has not the most both taken into account the detection that falls down to the ground of fainting, has had an effect on the user that height is shorter
Use.In cabin, child is stranded, and the people of outside cannot open hatch door, and child does not realize and presses go out button or the little behaviour of strength
Not making door open button, the people of outside is conventional to be called bank clerk or seeks help to 110, and bank clerk or people's police are led to
Crossing particular form could be from external opening hatch door.So being used for protecting the hatch door electronics of the ATM ATM protective cabin of remittee
System, for child, constitutes certain potential safety hazard.
Solve this potential safety hazard above, two methods that bank's aspect is currently employed: first uses Attended mode, people on duty
Member uses power-off, pushes the door open rescue trapped personnel with hand, say, that duty personnel's moment to wait in monitoring, takes after power-off
Manpower;The second solves this problem from remotely control exactly, when meeting the generation of this emergency when, and Field Force
Can dial the phone at bank monitoring center, Surveillance center can recall video recording, examines the situation at scene, and he can give a switch
Signal, protective cabin give opened, button of going out all is not operated by child, can make a phone call?.Also has a side used
Method, uses time-out to take function and solves trapped personnel, and in order to prevent other people from taking ATM protective cabin for a long time, ATM protects
The electronic system of cabin door is provided with timing and uses function, and being normally set up hatch door rear enclosed time that latches is 10 minutes, 10 minutes
Later, automatic unlocking hatch door, for stranded child, this method is not preferable way.
Well-known: the method that the existing detection faintness of existing ATM protective cabin hatch door electronic system falls down to the ground is the most not accurate enough, when hatch door closes
Close after latching, 1 meter of 2 space above nobody, assert that the people in cabin falls in a swoon (faintness falls down to the ground), exists and the people in cabin is pedaled down
Or bend over to carry out to pick up the action behavior such as thing, button shoestring and be considered as falling in a swoon (faintness falls down to the ground), people falls in a swoon after (faintness falls down to the ground) in fact
It is motionless, the method fallen down to the ground so the existing detection of existing ATM protective cabin hatch door electronic system is fainted, exist when in cabin
When people is pedaled down or bends over to carry out picking up the action row such as thing, button shoestring, hatch door unlocks, and other people can enter in cabin, does not now have anti-
The effect that only other people trail.
It is known that: ATM protection cabin has certain sound insulation function, and after once hatch door is closed, inside and outside cabin, sound can become
The least, people the most out of my cabin does not hears that the people in cabin speaks sound, and the people in cabin does not hears that people out of my cabin speaks sound.Meanwhile,
Once child stranded ATM protective cabin, typically can be frightened crying of a child wail and leave ATM fuselage.
It is known that: owing to rush is filled in nutrition, the child's height currently having is higher than 1.2 meters, but is latched in ATM cabin and not necessarily can grasp
Go out button.

2) detection identification stranded to child during the second human body sensor can't detect human body is being recognized:
Set and persistently reach T3 less than the input audio signal amplitude of T2 second more than the time setting threshold value when detection recognizes interval
Second, and within this T3 time second, do not assert that people faints fall down to the ground have child stranded in then assert cabin, the hatch door of locking is unlocked,
And by having the stranded voice help-asking information to be gone out of child in being located at loudspeaker output cabin out of my cabin, otherwise, without child in identification cabin
Stranded treat out;
S30, time hatch door is unlocked, and stop ongoing people and faint and fall down to the ground and the stranded detection of child identifies.
Above-described by there being people to faint the voice help-asking information fallen down to the ground and by being located at cabin in being located at loudspeaker output cabin out of my cabin
Having the stranded voice help-asking information to be gone out of child in outer loudspeaker output cabin, when hatch door is opened, loudspeaker stops output voice
Distress signals.
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 15 seconds.
Above-described detection recognizes interval and lasts up to more than the time setting threshold value less than the input audio signal amplitude of T2 second
To the T3 second, refer to: detection recognizes the interval of sound and is less than the T2 second, and this interval is more than less than the voice signal amplitude of T2 second
Set threshold value, and the duration continuously reaches the T3 second.
The above-described threshold value that sets refers to: the loudness of sound is as the input sound preserved by sound input circuit 8 detection during 40db
Tone signal amplitude.
Above method is that hatch door electronic system is carried out under remotely control off-line state.
