Description
Technical field
The present invention relates to ATM protective cabin hatch door electronic system, specifically relate to visit based on many sensings ATM protective cabin hatch door electronic system and its implementation of people.
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At present; the ATM of bank is withdrawn the money room (booth of withdrawing the money); in order to protect depositor to withdraw the money more safely; be provided with outside each ATM ATM (the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.
