GR1009844B - Desa 020 - an atm explosion prevention system - Google Patents

Abstract

The invented ATM explosion prevention system detects the breach of the external cash outlet at the ATM (A) front, via a sensor (4) connected to the programmable logic controller (1). With the help of switch (6) and two relays (5), the programmable logic controller (1) immediately activates the alarm system (D) as well as the internal siren (17) and, at the same time, releases the metal plate (9) from the electromagnet ( 8), which plate when falling blocks the money distributor’s opening (B) by covering this last. Two seconds after the initial activation, the programmable logic controller (1) commands the operation of the air compressor (11) and the pneumatic valve (14) and opens the solenoid valve (13) releasing the fire-extinguishing means from the cylinder-bottle (10) , which fire-extinguishing means diffuses -with the help of the pipe (15)- into the surrounding area of ??the money distributor (B), preventing or suppressing any ignition attempt.

Description

ATM EXPLOSION PREVENTION SYSTEM "PESA 020^

DESCRIPTION

The present invention relates to a system that is placed in

Automatic Teller Machine (ATM) and prevents explosion in

that of malicious actions of perpetrators, with the aim of stealing them

money in her safe.

[0002] Two corresponding systems that are known are placed ex

entirely inside the ATM safe. They have

gas detectors and have the ability to prevent explosion

and the occurrence of fire with the use of related gas that diffuses,

while simultaneously activating the alarm system. The disadvantage

of these systems is that they cannot prevent it

introduction of explosive gases or other explosive materials inside

of the safe.

The purpose of the present invention is to prevent it

possibility of explosion inside the safe which

contained in an ATM, which is attempted by perpetrators with the aim of

access and withdrawal of money placed on it.

Of the events that have been recorded, which are increasing

in recent years, the perpetrators have been found to be importing explosives

gas or mixture of gases or flammable liquids or explosives (eg dynamite

etc) inside the safe causing then

their ignition resulting in an explosion. To acquire

access to the safe the perpetrators first lift the

slot on the front of the ATM, from where the withdrawals are made

money. Behind the box office is the money dispenser, who

is a metal surface that moves horizontally between it

safe deposit box and the money exit box to the user

of the ATM transferring the money. From opening the box with

using a pipe or other means, introduce the explosive gas, the mixture

gases or flammable material inside the safe. In

in the case of using explosives, they attach it to the metal end

rod which they push so that it reaches its interior

safe deposit box.

The ignition of the explosive gas, the gas mixture, of

flammable material or explosives inside the safe,

it is possible to cause the safe to blow up and

therefore access to money by the perpetrators. At the same time, from

explosion causes significant damage to the ATM itself but also to

place where it is installed, such as a bank branch or

any other type of store (supermarket, etc.). Therefore,

in addition to the theft of money are caused important, material

damages, without the possibility of physical damage being excluded

damage or even loss of life.

[0005] The invention, as shown schematically in Figure 1, has the ability to directly detect the attempt to tamper with the ATM's external money outlet (A) with the help of a sensor (4). Arriving the signal from the sensor (4) to the programmable logic controller (1), it activates it and with the assistance of the switch (6) and a relay (5) the command is immediately given to the electromagnet (7), which releases a metal plate (9) which falls vertically, blocking the opening of the money dispenser (B). In this way, the possibility of introducing any explosive gas, gas mixture, flammable material or explosive substance into the interior of the safe (C) is prevented, thus eliminating the possibility of an explosion or fire inside it. At the same time, the alarm system (D) and the internal siren (16) are activated, thus reducing the available time that the perpetrators can have before the arrival of the Police. At the same time, the programmable logic controller (1), with the assistance of the switch (6) and a second relay (5), commands an air compressor (11) to operate by supplying air through a pipe (12) to a pneumatic valve (14). With the help of the pneumatic valve, it becomes possible to operate an electrovalve (13) placed at the outlet of the fire extinguisher bottle (10), allowing the approved and certified mixture of monoammonium phosphate and ammonium sulfate powder that it contains at a pressure of 13 atmospheres to be released with the help of a pipe (15) in the surrounding area of the money dispenser (B), where its tip is fixed. The fire extinguishing powder mixture extinguishes - suppresses any flammable material, in liquid, solid or gaseous form.

[0006] The components that make up the invention can be easily installed in any type of ATM, without requiring special interventions. The operation of the system is autonomous, since in addition to the two power supplies (2) one for the programmable logic controller (1) and one for the air compressor (11) it also has two 12VDC batteries (3), one for each of the aforementioned its components. Thus, the operation of the system is not prevented in the event of a power failure.
