Background technology
At present, the ATM machine withdrawal room (withdrawal pavilion) of bank, in order to which depositor is protected 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 ATM
ATM ATM (abbreviation ATM machine), ATM machine protective cabin are equipped with hatch door electronic system, carry out " one cabin of a people " (in principle, one
It is secondary can only there are one people into cabin) management.ATM machine protection hatch door electronic system is generally used 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
It is come out from the inside conducive to short people, the exit button mounting height 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 safety of ATM machine.Child is strayed into when falling in a swoon (faintness falls down to the ground) with ATM machine user button of entering and has in order to prevent
Unlocking function it is effective, only to 1 meter of more than 2 space in cabin, whether someone detects setting human body sensor, when 1 meter more than 2
Spatially someone, identification have ATM machine user, and the unlock work(for button of entering is shielded, and as 1 meter of more than 2 space nobody, assert nothing
ATM machine user or user, which faint, to fall 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 more than 2 space whether the human body sensor of someone, due to shadows such as temperature, agings
It rings, can cause to extend downwardly the spatial altitude of detection for 1 meter 2, numerous media are reported often:Because will be between 1 meter 1 to 1 meter 2 of height
Child's false-lock in ATM machine protective cabin, the people of outside can not open hatch door because human body sensor detect people assert cabin
Inside there is ATM machine user.This defect causes:When only stopping child in protective cabin, child will be unable to walk out protective cabin.
If by the height at human body sensor sensitivity drop bottom, i.e. human body sensor space exploration ground in cabin during 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 at this time, 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 goes not operating enabling by exit button or strength are small without consciousness
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, some potential safety problems is formed.
Solve this above security risk, 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 person, that is to say, that duty personnel's moment will keep in monitoring
It waits, takes manpower;Second is exactly to solve the problems, such as this from remote control, existing when meeting this emergency and occurring
Field personnel can dial the phone at bank monitoring center, and monitoring center can recall video recording, verify the situation at scene, he can give one
The signal of a switch, protective cabin to opening, child does not operate exit button, can make a phone call.There are one borrow
Method, with time-out occupy function solve trapped person, in order to prevent other people occupy ATM machine protective cabin for a long time, ATM machine is prevented
The electronic system for protecting cabin door is provided with timing using function, and it is 10 minutes, 10 points to be normally set up hatch door rear enclosed time that latches
After clock, automatic unlocking hatch door, for stranded child, this method is not ideal method.
It is well-known:The method that the existing existing detection faintness of ATM machine 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 more than 2 space 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
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 falls 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 machine protection cabin door electronic system is fainted exists and works as
People in cabin is pedaled down or bends over to carry out picking up thing, the hatch door unlock when action rows of button shoestring, other people can enter in cabin, rise at this time
Less than the effect for preventing other people from trailing.
It is well-known:ATM machine protection cabin has the function of certain sound insulation, 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 generally be frightened crying of a child wail.
It is well-known:Since rush is filled in nutrition, the child's height currently having is latched in ATM cabins and not necessarily can higher than 1.2 meters
Operate exit button.

Crossing to be located in the output of loud speaker out of my cabin cabin has child to be stranded voice help-asking information, and when hatch door is opened, loud speaker stops
Only export voice help-asking information.
Above-described T1 seconds is set as 4 seconds;The T2 seconds are set as 3 seconds;The T3 seconds are set as 15 seconds.
Above-described detection recognizes the time that input audio signal amplitude of the interval less than T2 seconds is more than given threshold
Persistently reach T3 seconds, refer to:The interval that detection recognizes sound is less than T2 seconds, and this interval is less than the voice signal amplitude of T2 seconds
More than given threshold, and the duration continuously reaches T3 seconds.
Above-described given threshold refers to:It is preserved when the loudness of sound is 40db by the detection of voice input circuit 8
Input audio signal amplitude.
Above method is hatch door electronic system with being carried out under remote control off-line state.
