Description

ATM protection cabin door electronic system based on multi-sensor human body recognition
Technical Field
The invention relates to an electronic system of an ATM protection cabin door, in particular to an ATM protection cabin door electronic system for identifying a human body based on multiple sensors and an identification and control method thereof.
Background
At present, in order to protect a depositor to draw money more safely, some ATM cash dispensers (cash dispensing booths) are provided with a closed protective cabin (similar to a closed protective cabin of a closed telephone booth) outside each ATM cash dispenser, and a protective door electronic system arranged on a cabin door manages one person in one cabin (in principle, only one person enters the cabin at a time). As shown in fig. 1, the shape of the protection cabin is generally designed as arc a and square B, both protection cabins generally have an automatic door locking (drop locking) function, the arc protection cabin door is usually opened/closed automatically, and the square protection cabin door is usually opened/closed manually or automatically. The door opening button is arranged inside and outside the protection cabin in the automatic door opening/closing mode, the door opening button is not arranged outside the protection cabin in the manual door opening mode, the door opening button outside the protection cabin is called as the door entering button, the door opening button inside the protection cabin is called as the door exiting button, and in order to be beneficial to short people to come out from the inside, the installation height of the door exiting button inside the protection cabin is about 1.1 m. The protection door electronic system that the hatch door set up is equipped with human body sensor in the cabin, detects someone in the cabin, and the automatic lock that falls after the hatch door is closed, and the people of outside can't open the door, must just can open the door from the inside button to prevent other people from following, protect the security that the people of the inside operated ATM. The human body induction sensor adopts a passive pyroelectric infrared detector (infrared detector for short), an active infrared correlation, a photoelectric switch, an ultrasonic wave and a microwave induction radar to detect various human body modes; in order to prevent children from entering the cabin door and prevent the cabin door from being locked when a user of the ATM turns faint (falls into a faint), a human body induction sensor is set to only identify whether people exist in a space above 1 m & lt 2 & gt in the cabin, when people exist in the space above 1 m & lt 2 & gt, the user is determined to use the ATM, the cabin door is automatically locked after being closed, when no people exist in the space above 1 m & lt 2 & gt, the user is determined not to use the ATM, and the cabin door is not locked after being closed; when the cabin door is closed and locked, no person is in the space more than 1 m & lt 2 & gt, and people in the cabin are determined to be faint. The design looks perfect, really has a very big defect, sets for the human body inductive sensor who detects whether someone is in the space more than 1 meter 2, because temperature, ageing etc. influence self parameter, leads to 1 meter 2 of the space height that will detect to prolong downwards and rise, the mistake is discerned people and animal below 1 meter 2, and human body inductive sensor once detects someone, and the hatch door electronic system carries out automatic lock after the hatch door is closed, and the affirmation is someone in the cabin and is used ATM. The defect that when only a child stays in the protection cabin, the child cannot walk out of the protection cabin, the human body induction sensor detects that the person in the cabin locks the cabin door, the cabin door can be opened only through the door opening button in the cabin, and the function of the door opening button outside the cabin is invalid, namely the cabin door cannot be opened through the door opening button outside the cabin. It is known that a child in the cabin may not reach the door opening button, and even if the child reaches the door opening button, there is a possibility that the door opening button may not be operated (without awareness) or with little effort. Therefore, when only children stay in the protection cabin, only bank workers can be called or help is required to be asked for 110, and the cabin door can be opened from the outside by the bank workers or the policemen in a special mode. Therefore, the ATM automatic teller machine protection cabin used for protecting the payee becomes a potential safety hazard for children and pet dogs.
Currently, two methods are used to solve this hidden trouble: the first method is characterized in that the person is on duty, the person on duty is powered off, and after the power is off, the person on duty pushes the door open to save the trapped person, namely, the person on duty is always on duty in monitoring and is labor-consuming; the second is to solve the problem from remote control, when the emergency occurs, a site person can dial the telephone of a bank monitoring center, the monitoring center can call out a video and verify the situation of the site, the site person can give a signal of a switch to open a protection cabin, and a child can not operate a door-out button and can call? The method also comprises a borrowing method, the trapped people are solved by utilizing the overtime occupation function, in order to prevent other people from occupying the ATM protection cabin for a long time, an electronic system of the cabin door of the ATM protection cabin is provided with a timing use function, the closing time of the cabin door after being locked is usually set to be 10 minutes, and the cabin door is automatically unlocked after 10 minutes, so that the method is not an ideal method for children.
Meanwhile, the existing method for detecting the faint land of the ATM protection cabin door electronic system is not accurate enough, after the cabin door is closed and locked, no person is in the space of more than 1 m & lt 2 & gt, the person in the cabin is determined to be faint (faint land), actions such as pedaling or bending down the person in the cabin to pick up things, and buckling shoelaces are also considered to be faint (faint land), and the person is not moved after faint (faint land), so that the existing method for detecting the faint land of the ATM protection cabin door electronic system is unlocked when the person in the cabin pedals or bends down to pick up things, buckle the shoelaces and the like, and other people can enter the cabin, and the effect of preventing other people from trailing cannot be achieved at the moment.
It is well known that: the prior ATM protection cabin door electronic system adopts a timing and calling mode to prevent people from occupying the ATM protection cabin for a long time, and has the problem that the people occupying the cabin can not actively exit.
As is well known, an infrared detector is not particularly described as being provided with a mechanical action part, a human body does not move in a detection range, the infrared detector cannot detect the existence of the human body, and only the infrared detector with the mechanical action part can detect the existence of the static human body.
As is well known, the protective cabin of the ATM has a certain sound insulation function, once the cabin door is closed, the sound inside and outside the cabin becomes very small, the voice of a person inside the cabin cannot be heard by a person outside the cabin, and the voice of a person outside the cabin cannot be heard by a person inside the cabin. Meanwhile, once a child or a pet dog is trapped in the ATM protection cabin, the child is generally threatened to womb and cry, and the pet dog is called continuously by Wang and Wang ….
Disclosure of Invention
The invention aims to solve the technical problem of providing an ATM protection cabin door electronic system based on multi-sensor recognition for a human body aiming at the defects of the existing ATM protection cabin door electronic system.
