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At present; the ATM of bank is withdrawn the money room (booth of withdrawing the money); in order to protect depositor to withdraw the money more safely; be provided with outside each ATM ATM (the similar closing protective cabin closing telephone booth) that have closes protective cabin (room); i.e. one one, cabin ATM ATM (abbreviation ATM); ATM protective cabin is provided with hatch door electronic system, carries out " people one cabin " (in principle, a people once can only be had to enter cabin) management.ATM protection hatch door electronic system typically uses and is equipped with door open button inside and outside protective cabin, the outer set door open button of protective cabin is on button of entering, door open button set in protective cabin tells a button, for the shortest 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; when the human body sensor that hatch door electronic system is arranged in cabin has detected people; the unlocking function of button of entering is shielded; door cannot be opened by the people of outside; door could must be opened by button in operational window; thus preventing other people from trailing, the people protecting the inside operates the safety of ATM.In order to prevent child be strayed into ATM make employment fall in a swoon (faintness falls down to the ground) time the unlocking function that button has of entering effective, only in cabin 1 meter of 2 space above, whether someone detects to set human body sensor, when having people in 1 meter of 2 space above, assert there is ATM user, the unblock merit of button of entering is shielded, as 1 meter of 2 space above nobody, assert faints 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, owing to temperature, aging etc. affects, can cause downwardly extending the spatial altitude of detection for 1 meter 2, numerous media are reported often: because the child's false-lock between height 1 meter 1 to 1 meter 2 cannot be opened hatch door ATM protective cabin, the people of outside, because human body sensor detects that people has ATM user in assert cabin.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 dropped at the end when arranging, i.e. in human body sensor space exploration distance cabin, the height on 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, and has an effect on the shorter user of height and uses.In cabin, child is stranded, the people of outside cannot open hatch door, and child does not realize and presses button or the little operation of strength not door open button of going out, the people of outside conventional calling bank clerk or seek help to 110, bank clerk or people's police could be from external opening hatch door by particular form.So being used for protecting the hatch door electronic system of the ATM ATM protective cabin of remittee, for child, constitute certain potential safety hazard.
Solve this potential safety hazard above, two methods that bank's aspect is currently employed: first uses Attended mode, and duty personnel uses power-off, push the door open rescue trapped personnel with hands after power-off, say, that duty personnel's moment to wait in monitoring, takes manpower;The second solves this problem from remotely control exactly, when meeting the generation of this emergency when, Field Force can dial the phone at bank monitoring center, Surveillance center can recall video recording, examining the situation at scene, he can give the signal of a switch, and protective cabin is opened, button of going out all is not operated by child, can make a phone call?.Also has a method used, use time-out to take function and solve trapped personnel, in order to prevent other people from taking ATM protective cabin for a long time, the electronic system of ATM protective cabin hatch door is provided with timing and uses function, being normally set up hatch door rear enclosed time that latches is 10 minutes, after 10 minutes, and 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, after hatch door is closed and is latched, 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 down or bends over to carry out picking up thing, the action behaviors such as button shoestring are 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 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 the people in cabin is pedaled down or bends over to carry out picking up thing, during the action row such as button shoestring, hatch door unlocks, other people can enter in cabin, now do not have the effect preventing other people from trailing.
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, and 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.
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 operate button of going out.
