Background technology
At present, the ATM machine 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 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 to have a 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
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, thus prevent other people trail, protect the inside
People operates the security 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(shielding to button of entering, 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
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 machine protective cabin, the people of outside 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 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 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 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 particular form
Could be from external opening hatch door.So for protecting the hatch door electronic system of the ATM ATM protective cabins of remittee, to small
