A kind of cabin door electronic system of ATM machine protective cabin and its realization method

Abstract

The invention discloses an electronic system for an ATM (automated teller machine) protection cabin door and an implementing method of the electronic system. The electronic system is characterized in that a cabin door controller unit is connected with a human body sensor, an acoustic input circuit and an acoustic output circuit, wherein the sensitivity of the human body sensor is controlled by a mode I and a mode II of the human body sensor; a microphone of the acoustic input circuit is arranged in a cabin, and a loudspeaker of the acoustic output circuit is arranged outside the cabin; the height of detection space away from the ground in the cabin when the human body sensor is in the mode I is smaller than that of the detection space away from the ground in the cabin when the human body sensor is in the mode II, and a step is arranged in front of an ATM. According to the method, during a period that an entry button unlocking function keeps shielded, the human body sensor working in the mode I and the mode II alternately performs following settings: the condition that a child gets trapped is determined and unlocking is performed when the following conditions are met: (1) the condition that duration when an input acoustic signal amplitude with the interval smaller than a set value is larger than a set threshold value reaches a specified value is detected and recognized; (2) during the duration, the condition that nobody faints and falls to the ground is determined, and the cumulative time when a human body is detected by the human body sensor in the mode II accounts for lower than 30% of the total working time of the sensor in the mode II.

Description

technical field [0001] The invention relates to an electronic system of a protective cabin door of an ATM machine, in particular to an electronic system of a protective cabin hatch of an ATM machine for detecting human bodies in a plurality of spaces and a realization method thereof. Background technique [0002] At present, in the ATM machine withdrawal room (cash booth) of the bank, in order to protect depositors from withdrawing money more safely, some of them are equipped with (closed protective cabins similar to closed telephone booths) closed protective cabins (rooms) outside each ATM automatic teller machine, i.e. One cabin has one ATM automatic teller machine (referred to as ATM machine), and the ATM protective cabin is equipped with a cabin door electronic system for "one person, one cabin" (in principle, only one person can enter the cabin at a time) management. The electronic system of the ATM protective cabin door is generally equipped with a door-opening button ...

AI Technical Summary

Problems solved by technology

At the same time, once a child is trapped in the ATM protective cabin, they will generally be frightened and cry and leave the ATM machine body. Of course, they may return to the ATM machine for a short time.

In the process of using the ATM, normal users may step down or bend over to pick up things, buckle shoelaces and other factors, which will cause the body to move briefly below the height of 1.2 meters from the bilge floor.
