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.
If human body sensor sensitivity is dropped to the height at bottom, i.e. human body sensor space exploration ground in cabin when setting
Degree is lifted up being more than 1 meter 2, does not both take into account the detection that falls down to the ground of fainting now, has an effect on the shorter user of height and uses.It is small in cabin
Child is stranded, and the people of outside can not open hatch door, and child does not have consciousness to go not operating enabling by exit button or strength are small
Button, the people of outside seek help frequently with calling bank clerk or to 110, and bank clerk or people's police pass through special side
Formula could be from external opening hatch door.So for protecting the hatch door electronic system of the ATM ATM protective cabins of remittee, it is right
For child, certain potential safety hazard is formed.
This potential safety hazard more than solving, currently employed two methods in terms of bank:First uses Attended mode, value
Personnel are kept using power-off, is pushed the door open after power-off with hand and saves trapped personnel, that is to say, that duty personnel's moment will keep in monitoring
Wait, take manpower;Second is exactly to solve this problem from remote control, existing when meeting this emergency and occurring
Field personnel can dial the phone at bank monitoring center, and Surveillance center can recall video recording, examine the situation at scene, and he can give one
The signal of individual switch, protective cabin to opening, child does not operate to exit button, can made a phone call.Also one borrow
Method, with time-out take function solve trapped personnel, in order to prevent other people from taking ATM protective cabin for a long time, ATM is prevented
The electronic system of shield cabin door is provided with timing and uses function, is normally set up hatch door and latches the rear enclosed time as 10 minutes, 10 points
After clock, automatic unlocking hatch door, for stranded child, this method is not preferable method.
It is well-known:The method that the existing existing detection faintness of ATM protection cabin door electronic system falls down to the ground is also not accurate enough, works as cabin
After door closing latches, 1 meter of 2 space above nobody, assert that the people in cabin falls in a swoon (faintness falls down to the ground), exist and the people in cabin is pedaled
Lower or bend over to carry out to pick up the action behaviors such as thing, button shoestring and be considered as falling in a swoon (faintness falls down to the ground), people is fallen in a swoon in fact, and (faintness is fallen
Ground) after be motionless, the method that falls down to the ground so the existing detection of existing ATM protection cabin door electronic system is fainted, exist and work as
Hatch door unlocks when people in cabin is pedaled down or bends over to carry out picking up the action rows such as thing, button shoestring, and other people can enter in cabin, now rise
Less than the effect for preventing that other people from trailing.
It is well-known:ATM protection cabin has certain sound insulation function, after hatch door is closed, sound meeting inside and outside cabin
Become very small, i.e., people out of my cabin does not hear people's sound of speaking in cabin, and the people in cabin does not hear people's sound of speaking out of my cabin.Together
When, once child is stranded ATM protective cabins, can typically be frightened crying of a child wail and leave ATM fuselage, being also possible to certainly can be short
Before temporarily returning to ATM.And during normal users use ATM, it may pedal down or bend over to carry out picking up thing, button shoestring etc.
Factor can cause body of short duration in the activity below 1.2 meters of bilge ground level.
It is well-known:Because rush is filled in nutrition, the child's height currently having is higher than 1.2 meters, but is latched in ATM cabins and not necessarily can
Operate exit button.

Set and continue when detection recognizes interval less than the input audio signal amplitude of T2 seconds more than the time of given threshold
Reach the T3 seconds, and institute's cumulative time that the second human body sensor detects human body is recognized within this lasting T3 time second
Less than the 30% of T3 times second is accounted for, and faints and falls down to the ground without identification people within this lasting T3 time second, then is had in identification cabin small
Child is stranded, and the hatch door of locking is unlocked, and has the stranded voice to be gone out of child to ask by being located in loudspeaker output cabin out of my cabin
Information is rescued, otherwise, assert to be stranded without child in cabin and treats out;
S30, when unlocking hatch door, and stop ongoing people and faint to fall down to the ground and the stranded detection identification of child.
It is above-described that the voice help-asking information and lead to that someone's faintness falls down to the ground in cabin are exported by the loudspeaker being located at out of my cabin
Crossing the loudspeaker being located at out of my cabin and exporting has the stranded voice help-asking information to be gone out of child in cabin, when hatch door is opened, loudspeaker stops
Only export voice help-asking information.
The above-described T1 seconds are arranged to 3 seconds;The described T2 seconds are arranged to 3 seconds;The described T3 seconds are arranged to 20 seconds.
Above-described given threshold refers to:Detect what is preserved by sound input circuit 8 when the loudness of sound is 40db
Input audio signal amplitude.
Above-described detection recognizes the time that interval is more than given threshold less than the input audio signal amplitude of T2 seconds
Persistently reach the T3 seconds, refer to:The interval that detection recognizes sound is less than the T2 seconds, and this interval is less than the voice signal amplitude of T2 seconds
More than given threshold, and the duration continuously reaches the T3 seconds.
Above-described setting is more than given threshold when detection recognizes interval less than the input audio signal amplitude of T2 seconds
Time persistently reach the T3 seconds, and recognize the second human body sensor within this lasting T3 time second and detect human body
Institute's cumulative time accounts for less than the 30% of T3 times second, and faints and fall down to the ground without identification people within this lasting T3 time second, then recognizes
Determine there is child to be stranded in cabin, refer to:Recognize interval less than the T2 seconds input audio signal amplitude be more than given threshold when
Between persistently reach the T3 seconds during, do not assert that people faints and fall down to the ground, and the second human body sensor recognized detects people
Institute's cumulative time of body accounts for less than the 30% of this lasting T3 time second, then assert in cabin has child to be stranded.For example know in detection
Input audio signal amplitude of the interval less than 3 seconds is clipped to more than the Time Continuous of given threshold to reach in 20 second time, and at this
Continue to faint without identification people in 20 second time and fall down to the ground, and the second human body sensing recognized in this continues 20 second time passes
Sensor detects that institute's cumulative time of human body is that 3 seconds, then the 3 of institute's cumulative time second divided by 20 seconds are less than 30%, therefore assert in cabin
There is child to be stranded.
Above method is hatch door electronic system with being carried out under remote control off-line state.
