Description

The invention relates to a system for securing containers for storing valuables (safes), in particular cash dispensers, from the risk of destruction by the introduction of a combustible gas or gas mixture and an explosion thereof, according to claim 1.

To an increasing extent, money, gaming, merchandise and ticket vending machines are exposed to a wide variety of attacks. Among other things, it is known that in cash, game, goods and ticket vending explosive gas and / or explosive gas mixtures are introduced to ignite the gas or the gas mixture in the machine or in the closed container. Due to the explosion money, game, merchandise and ticket vending machines are destroyed, so the perpetrator access to the inside of the money, game, merchandise and ticket machines is enabled. For example, acetylene-oxygen gas mixtures are used in this context.

In order to prevent blasting of money, game, merchandise and ticket machines, so far different methods are available. On the one hand, the oxygen content in a machine that is to be protected can be reduced. Furthermore, it is known to chemically render inert the combustible gas introduced. For this purpose, inert gases are introduced in the ticket or ATM. However, in this connection, storage of the inert gas within the objects to be protected is often very difficult due to lack of space. In addition, the cost of inert gas is very high and the maintenance of the machines, which are equipped with an inert gas, very expensive.

The previously used methods for preventing blasting based on the fact that the gas concentration or the composition of the atmosphere in the container or in the ticket or ATM is monitored and detected by a detector. The problem with using such detectors for gas concentration or composition of the atmosphere in a container or room u. a. in that these detectors can become dirty or wear out. In addition, such detectors can be manipulated. Since the activation or initiation of countermeasures in these known systems is dependent on the detection of the gas concentration or composition of the atmosphere in space, this represents a high hazard with respect to the failure of such systems.

In addition, it is necessary in the chemical inerting to provide a container with inert gas within the money, game, goods and ticket machines. Due to the example constructionally small money and / or ticket machines installation of all components of this system is very difficult and possible in many cases only outside of the objects to be protected. This represents a high risk with regard to manipulation and foreign influence by possible perpetrators.

The object of the present invention is therefore to provide a structurally simple, effective system for securing containers for storing valuables (safes), in particular cash dispensers, against the risk of destruction by the introduction of a combustible gas or gas mixture and an explosion thereof , With the help of such a further developed system, the aforementioned disadvantages of the known prior art are to be overcome.

The object described is achieved by a system for securing containers for the storage of valuables (safes), in particular cash dispensers, from the risk of destruction by the introduction of a combustible gas or gas mixture and an explosion thereof, according to claim 1.

The inventive system is based on the fact that within the respective container, ie within a container for the storage of valuables, such. B. within a cash dispenser and / or within a ticket vending machine and / or within a vending machine and / or within a gaming machine at least one ignition module is provided which generates sparks at regular or irregular intervals, whereby a gas or gas mixture introduced into the container accordingly regularly or irregularly fizzy.

In other words, within a container for storing valuables, a system is provided with an ignition module, wherein the ignition module generates sparks, wherein the spark generation takes place regardless of whether a combustible gas or a combustible gas mixture is introduced into the container. The generation of sparks is therefore also carried out in an unmanipulated state.

The generated sparks ignite the introduced gas or gas mixture, even before it reaches a dangerous volume of gas or dangerous gas concentration within the space to be protected and ignites this, so that the same fizzles. As soon as a combustible gas or gas mixture is introduced into the container for the storage of valuables, the explosive gas or explosive gas mixture therefore already fumes before it reaches a dangerous gas concentration. The risk to third parties and damage to buildings and the containers or premises themselves is avoided because no more explosive gas can escape from the closed containers or premises.

Potential perpetrators are thus denied the opportunity to open by introducing explosive gases, closed containers or premises or destroy them or break up by gas explosion.

The at least one ignition module may have two spaced-apart electrical contacts between which a spark ignites upon application of a predetermined electrical voltage. Due to the spark jump over a possibly initiated combustible gas or gas mixture can be ignited and bled.

The at least one ignition module is preferably arranged approximately centrally within the container, so that the ignition and deflagration can take place safely within the container, regardless of the location of the gas inlet.

The timing of the spark generation of the at least one ignition module is preferably in the range of 0.5 to 5.0 seconds, in particular in the range of 1.5 to 3.0 seconds. Such a timing with respect to the spark to be generated guarantees a regular and rapid ignition of potentially initiated or optionally introduced gases or gas mixtures.

In a further embodiment of the invention, at least three, in particular four to eight, ignition modules can be arranged distributed approximately uniformly over the interior of the container in the interior of the container. Due to a uniform distribution of multiple ignition modules within a container for the storage of valuables, such. B. within a cash dispenser and / or within a ticket vending machine, introduced gases or gas mixtures can be ignited as soon as possible regardless of their point of introduction. In addition, the uniformly distributed ignition modules ensure a correspondingly uniformly distributed ignition and deflagration of the introduced gas or gas mixture.

If the system according to the invention provides for a plurality of ignition modules, these ignition modules can be operated jointly, in groups or preferably independently of each other, ie. H. be ignitable independently. If a plurality of ignition modules are provided in the system according to the invention, these ignition modules will preferably be ignited in each case crosswise within the interior of the container, d. H. for example, from bottom left to top right, and from top left to bottom right or vice versa.

In other words, by means of a control unit, for example, the successive ignition of a plurality of ignition modules can be controlled in such a way that they generate ignition sparks in succession in a specific sequence. The sequence of the ignition modules to be activated successively is preferably carried out as a function of the spatial conditions within the container for the storage of valuables.

In a further embodiment of the invention, a pressure sensor may be provided, via which a deflagration of the introduced gas or gas mixture is detectable, whereby an alarm signal is triggered. Upon detection of a pressure change by means of a pressure sensor and optionally via an associated or self-sufficient monitoring and control unit, the fuming of an introduced gas or gas mixture can be detected. For example, by means of a monitoring and control unit, a signal can then be output. The signal can be both an audible alarm signal and a silent alarm. For example, if a silent alarm is canceled, the likelihood that the perpetrator or the perpetrator can still be found at the scene of the crime can be increased. A forwarded by the pressure sensor to the control unit signal can also be used to trigger an audible alarm to trigger, for example, further alarm systems and / or to convict the perpetrator at the scene and / or to make the loot or bills worthless and / or or inform residents or residents about the crime, so that the perpetrator leaves or leaves the crime scene.

The pressure sensor may be, for example, a differential pressure sensor. The pressure sensor can be designed as a separate component and / or as a component of a monitoring and control unit.

In connection with the detection of a deflagration of the introduced gas or gas mixture, it may further be provided that the clock sequence of the spark generation can be shortened. In other words, the timing of spark generation is changed after a deflagration of the introduced gas or gas mixture such that in a same period more sparks are generated than before, the clock frequency is thus increased or increased.

Preferably, several or individual ignition modules can be designed to be self-sufficient, ie individual or multiple ignition modules can be designed and installed in a container such that they function or work independently of one another. For example, each ignition module can be assigned an emergency power source. The emergency power source is preferably a battery and / or an accumulator. This allows even in case of power failure or in a manipulation of the power supply of the container, eg. B. a money, game, merchandise or ticket machines a secure power supply of the ignition modules or equipped with an emergency power source ignition module.

Preferably, each ignition module comprises the electronics for generating a spark. This means that if one ignition module fails, the other ignition modules will continue to operate autonomously.

Furthermore, it can be provided that a monitoring and control unit is assigned to each ignition module, which monitors the spark generation of the ignition module and optionally adjusts the energy for spark generation. In this case, for example, each ignition module may be assigned a separate monitoring and control unit. Furthermore, it is conceivable that only one common monitoring and control unit is assigned to each ignition module. Accordingly, it is possible to individually control each ignition module and to monitor and control the actual function, namely the spark generation of an ignition module, starting from a monitoring and control unit.

Accordingly, it is possible to readjust the energy necessary for generating a spark in the sense of a control loop. For example, it is conceivable to monitor one or more ignition module (s) to determine whether a spark is generated. If this is not the case, the energy or the electrical voltage for spark generation can be increased. The readjustment or increase of the energy for ignition spark generation is preferably carried out up to a predetermined threshold.

For example, a monitoring and control unit provided within the system according to the invention can monitor the function of all ignition modules. If a fault message is detected with regard to the ignition modules or a single ignition module, a signal for requesting a service employee can be generated. Furthermore, the output of an alarm message or the activation of other safety devices is possible.

The system according to the invention may further comprise a dummy module or a plurality of dummy modules for imitating ignition noises of an ignition module. Accordingly, the dummy modules or the dummy module serve to create or mimic the noises which resemble the ignition noise of an ignition module. This serves to manipulate security and confusion of a possible offender.

Preferably, the electrical contacts of the at least one ignition module are designed to be interchangeable. Accordingly, it is possible to be able to replace the electrical contacts after a corresponding wear, so that does not need to be replaced the complete system for securing containers for the storage of valuables.

The advantages of the system according to the invention are, on the one hand, that no elaborate sensor system for detecting the gas concentration or for detecting the composition of the atmosphere in the room to be secured is needed as a trigger of countermeasures. In addition, there is an indefinite protection, since no inert gas must be provided. The system according to the invention enables an immediate deflagration of all flammable gases present on the market, even before a volume of highly flammable gas or gas mixture forms in the space to be protected, leading to the destruction of the container bounding this space.

In addition, the system according to the invention is characterized by low service and maintenance and by a small footprint. All necessary and optional components of the system according to the invention, such as one or more ignition modules and / or pressure sensor and / or emergency power source and / or monitoring and control unit and / or Dummymodul can be arranged within the container to be protected, so that they are installed tamper-proof. A foreign influence by perpetrators from the outside is excluded in this case.

Further embodiments of the invention will become apparent from the dependent claims and combinations selbiger.

The invention will be described with reference to an embodiment which is explained in more detail with reference to the figures. Hereby show:

1 the schematic structure of a cash dispenser with a system according to the invention; and

2 the schematic structure of a cash dispenser with a system according to the invention comprising three ignition modules.

In the following description, the same reference numerals are used for identical and equivalent parts.

1 shows the schematic structure of a cash dispenser 10 with a system according to the invention for securing such a cash dispenser 10 before the risk of destruction by the introduction of a combustible gas or gas mixture and an explosion thereof.

The cash dispenser 10 has a housing 11 on, wherein the inventive system within the housing 11 in the interior 18 the cash dispenser 10 is trained. For orientation of the arrangement of the individual components comprised by the system according to the invention, the screen is 12 as well as the slot 13 shown for supplying a magnetic and / or chip card. The system according to the invention comprises according to 1 an ignition module 20 which generates sparks at regular or irregular intervals, whereby a gas or gas mixture introduced into the container is correspondingly regularly or irregularly deflagrated.

The ignition module 20 has two spaced electrical contacts 21 on, between which sparks after applying a predetermined voltage an ignition spark. The illustrated ignition module 20 is about central in the interior 18 the cash dispenser 10 or centrally within the housing 11 arranged. This corresponds to a preferred arrangement of the ignition module 20 since a safe ignition and deflagration of an introduced combustible gas or gas mixture can take place regardless of the location of the introduction of the same. The timing of spark generation of the ignition module 20 is in the range of 0.5 to 5.0 seconds, especially in the range of 1.5 to 3.0 seconds. The ignition module 20 is with a monitoring and control unit 25 connected or this monitoring and control unit 25 assigned.

The monitoring and control unit 25 supplies the ignition module 20 initially with power and with the specification regarding the timing of the spark generation. The monitoring and control unit 25 is by means of a power line 15 connected to a power grid. Preferably, the power line 15 laid directly in a wall or a floor, so that a manipulation or a severing of the power line 15 from the outside is not or only extremely difficult.

Between the two electrical contacts 21 As already described, a spark is generated, preferably every 1.5 to 3.0 seconds. If no ignitable gas or gas mixture is introduced or located in the housing, can within the housing 11 no explosion or deflagration take place. Is in the housing such a flammable gas or gas mixture such. B. initiated an acetylene-oxygen gas mixture, which is in the housing 11 ignited gas quantity or mixture of gas mixture, so that it fizzles. Since the introduced combustible or highly flammable gas or gas mixture immediately, ie ignited after the introduction of very small amounts and fizzles, there is no risk of explosion in cash dispensers 10 and a destruction of the same, since the deflagration takes place even at relatively low gas or gas mixture quantities. The explosion of explosive gases is therefore already carried out at a time at which the gases introduced do not reach a dangerous gas concentration, so that the risk to third parties and damage to buildings and the cash dispenser 10 even avoided. In addition, no more explosive gas from the closed cash dispenser 10 escape.

By preferably in the area of the soil 14 of the housing 11 arranged pressure sensor 30 a deflagration of the introduced gas or gas mixture can be detected. The pressure sensor 30 is with the monitoring and control unit 25 connected, which preferably also in the area of the soil 14 is arranged. Alternatively, the pressure sensor 30 also within the monitoring and control unit 25 be installed. Once the pressure sensor 30 detects a deflagration of an introduced gas or gas mixture and thus detects a manipulation or blasting attempt can by means of the monitoring and control unit 25 an alarm signal is triggered. It can be a silent alarm so that the perpetrators can still be made at the scene by surveillance personnel or the police. Furthermore, it is conceivable that the alarm signal is output via a sounder as audible alarm signal, so that, for example, residents and / or passers-by become aware of the fact.

Preferably, the timing of the spark generation with respect to the ignition module 20 shortened after detection in a first deflagration. This means that further introduced gas can be ignited and puffed faster. A destruction or demolition of the cash dispenser 10 can therefore be reliably prevented even at a high gas introduction rate.

The ignition module 20 is an emergency power source 35 assigned. Preferably, it is the emergency power source 35 an emergency power accumulator or a backup battery. The operating time with full protection function can be due to the emergency power supply in case of power failure or power failure 35 several hours.

The emergency power accumulator 35 is of course connected to the mains and is constantly charged.

Because the ignition module 20 the monitoring and control unit 25 is assigned, the ignition spark of the ignition module 20 be monitored, where appropriate, the energy for spark generation is nachregelbar. In other words, from the monitoring and control unit 25 is first checked if the ignition module 20 generates a spark. If this is not the case, the amount of the previously determined electrical voltage at the electrical contacts 21 increase. The electrical voltage or the energy required for spark generation is preferably raised to a certain limit or threshold value so that no dangerously high currents flow within the system according to the invention. The electrical contacts 21 of the ignition module 20 subject to permanent ignition sparking wear (burning of the contact tips). To the electrical contacts 21 of the ignition module 20 to be able to replace, they are on the ignition module 20 exchangeable mounted.

In 2 is a cash dispenser 10 with a housing 11 represented, wherein the system formed there according to the invention three ignition modules, namely the ignition modules 20 . 20 ' and 20 '' , includes. Preferably, the ignition module 20 ' with associated emergency power source 35 centrally within the housing 11 arranged. The second ignition module 20 ' and the associated emergency power source 35 is in the illustrated example, which corresponds to a particularly preferred embodiment, in the left upper portion of the housing 11 arranged. The third ignition module 20 '' is on the ground 14 of the housing 11 arranged. This also applies to the ignition module 20 '' associated emergency power source 35 ,

Accordingly, this includes in 2 illustrated system according to the invention three ignition modules, which is approximately uniform over the interior 18 of the container or the housing 11 are arranged distributed. The timing of spark generation of the ignition modules 20 . 20 ' and 20 '' is in the range 1.5 to 3.0 seconds. The three illustrated ignition modules 20 . 20 ' and 20 '' are particularly preferably switched together or designed to be ignitable. For this purpose, all ignition modules 20 . 20 ' and 20 '' with the monitoring and control unit 25 connected. The simultaneous or simultaneous ignition of the three ignition modules 20 . 20 ' and 20 '' has the advantage of having an ignition at different positions of the housing at the same time 11 takes place, so that with higher energy, an introduced gas can be ignited, regardless of where the gas in the housing 11 is initiated.

The position of the monitoring and control unit 25 corresponds to the position as shown in 1 is shown. Also the pressure sensor 30 is in the embodiment according to 2 on the ground 14 of the housing 11 , Because every ignition module 20 . 20 ' and 20 '' a separate emergency power source 35 is assigned, the ignition modules 20 . 20 ' and 20 '' be operated independently from each other.

Furthermore, each ignition module includes the complete electronics for generating the spark, so that this via the respective associated electrical contacts 21 can be generated. This means that in case of failure of one of the illustrated ignition modules 20 . 20 ' and 20 '' the other ignition modules continue to operate autonomously. The three illustrated ignition modules 20 . 20 ' and 20 '' Consequently, they can work independently, with each individual ignition module 20 . 20 ' and 20 '' can be monitored by means of sensors, so that via the monitoring and control unit 25 always the full functionality of the three ignition modules 20 . 20 ' and 20 '' can be determined.

Preferably, the ignition modules 20 . 20 ' and 20 '' with a trigger line and a monitor line with the monitoring and control unit 25 connected. This relationship also applies to the embodiment according to 1 , Accordingly, each ignition module 20 . 20 ' and 20 '' individually controlled. In addition, the actual function, namely the spark generation of the respective ignition module 20 . 20 ' and 20 '' from the monitoring and control unit 25 monitored.

By permanent monitoring of each individual ignition module 20 . 20 ' and 20 '' In case of a fault, a message can be issued. The message is preferably forwarded to a monitoring service provider who, for example, the decommissioning of the cash dispenser 10 and / or the repair of the cash dispenser 10 can cause.

Also in the formation of a system according to the invention with a plurality of ignition modules, it is provided to shorten the cycle of spark generation after detection of a first deflagration of the introduced gas or gas mixture. The clock frequency of the spark generation is thus increased by the time intervals between the individual sparks are shortened.

As in the example shown in FIG 2 every ignition module 20 . 20 ' and 20 '' the monitoring and control unit 25 is assigned, the Spark generation of each individual ignition module 20 . 20 ' and 20 '' monitored and optionally adjusted independently of the other ignition modules, the energy for ignition generation. Accordingly, each ignition module 20 . 20 ' and 20 '' , which is equipped with its own high-voltage module, are individually readjusted. Also in 1 illustrated single ignition module 20 can have its own high voltage module.

The system further includes a dummy module 40 , This dummy module 40 generates noises, which the ignition noise of the ignition modules 20 . 20 ' and 20 '' are imitated. According to the dummy module 40 suggest that at the designated place an ignition module 20 is placed. In order to keep the number of ignition modules for cost reasons relatively low, it is provided such Dummymodule 40 at other positions of the housing 11 to install.

It should be noted that in addition to the illustrated embodiment, in which each ignition module 20 a separate emergency power source 35 it is theoretically also conceivable that the system according to the invention also in the use of multiple ignition modules 20 only an emergency power source 35 that has with all the ignition modules 20 . 20 ' and 20 '' connected is.

It can be stated that the present system according to the invention has no sensors for detecting the gas concentration or no sensors for detecting the composition of the atmosphere in the cash dispenser 10 or in the housing 11 can be applied. In addition, the illustrated system is easy to install and can also be retrofitted in existing systems. It should also be noted that all the above in connection with the embodiments according to 1 and 2 described parts taken alone or in any combination, in particular the details shown in the drawings are claimed as essential to the invention.

In addition to the above, the following initial considerations of the inventors are pointed out, which form part of the description of the invention:
Increasingly, money and ticket machines are the target of various attacks, the currently most aggressive method is the attack in explosive gas.

• – Die Täter haben kein physisches Gegenüber
• – Es sind keine Waffen erforderlich
• – Der Angriff kann auch nachts erfolgen
• – Nur einfaches leicht erhältliches Werkzeug erforderlich
• – Relativ hohe Beutessummen vor allem bei Geldausgabeautomaten
• – Geringer Zeitaufwand für die Tät

This approach seems simple and lucrative, since with little time and material expenditure, as well as low risk, for the offenders relatively high booty totals are to be expected.

• - The perpetrators have no physical counterpart
• - No weapons required
• - The attack can also be done at night
• - Only simple, easily available tool required
• - Relatively high booty totals especially at cash dispensers
• - Low time spent on the tattoo

These attacks are carried out not only by professional gangs but increasingly by amateurs (freeloaders) who have little knowledge of handling explosive gases.

To counteract this approach, the inventors have developed a system that prevents the explosion and future potential offenders have the incentive to carry out such attacks.

The inventors treat here acetylene / oxygen gas mixture, as this has the highest explosive energy and thus represents the most dangerous and most common threat.

• – Wie werden diese Angriffe durchgeführt?
• – Welche Gase werden bei den Angriffen verwendet?
• – Wie viel Gas wird benötigt?
• – Wovon ist das Erreichen eines explosionsfähigen Gemisches abhängig?
• – Welches Gemisch ist bei Acetylen/Sauerstoff erforderlich?
• – Wie können brennbare Gase unschädlich gemacht werden?
• – Initialkosten des Systems?
• – Installationsaufwand des Systems?
• – Wartungsaufwand des Systems?

The design of the explosive gas detonation system was designed according to the following criteria:

• - How are these attacks carried out?
• - Which gases are used in the attacks?
• - How much gas is needed?
• - What depends on reaching an explosive mixture?
• - Which mixture is required for acetylene / oxygen?
• - How can inflammable gases be neutralized?
• - initial costs of the system?
• - installation costs of the system?
• - Maintenance of the system?

How are these attacks carried out?

• – Bestimmung eines Standortes an dem die Täter zum Tatzeitpunkt unge stört sind
• – Schaffung einer Zugangsöffnung für den Gasschlauch mittels Hammer, Schraubendreher oder ähnlichem Werkzeug bzw. Nutzung von vorhande nen Öffnungen
• – Abkleben von Öffnungen und Schlitzen an Geld- und Fahrkartenautomaten mit Klebeband, um ein Austreten des Gases beim Befüllen zu verhindern bzw. zu minimieren.
• – Einführen eines Gasschlauches in die Öffnung
• – Befüllung mit brennbarem Gasgemisch
• – Zündung des eingefüllten Gasgemisches mittels elektrischer oder pyrotech nischer Vorrichtung

When analyzing attacks on ATMs and ticket machines, we found that the perpetrators follow the following pattern in most cases:

• - Determination of a location where the perpetrators are unharmed at the time of the offense
• - Creation of an access opening for the gas hose by means of a hammer, screwdriver or similar tool or use of existing openings
• - Masking of openings and slots on cash machines and ticket machines with tape to prevent leakage of the gas during filling or minimize.
• - Inserting a gas hose into the opening
• - Filling with combustible gas mixture
• - Ignition of the filled gas mixture by means of electrical or pyrotech African device

Which gases are used in the attacks?

When attacking money and ticket machines, an acetylene oxygen mixture is used in most cases. This combustible gas is so attractive because it is very easy to obtain and the mixture has a very wide explosion range LEL and OEG. (lower and upper explosion limit). For the perpetrators, this means that even without precise knowledge of the mixing ratio, an optimal, explosive mixture is achieved quickly.

Advantages of acetylene / oxygen gas mixture:

• - Easy to obtain
• - Mixing ratio uncritical
• - High explosive force

Other combustible gases may be used. However, these require precise knowledge of concentration and mixing ratio in order to achieve a sufficient explosion effect.

• – Freiem Luftvolumen im geschlossenen Behältnis bzw. Raum (je nach Größe und Einbauten)
• – Dichtheit der angegriffenen Objekte (Öffnungen eventuell abgeklebt etc.)
• – Ausströmmenge pro Sekunde des eingeleiteten Gases (z. B. physikalische Begrenzung bei Acetylen max. 1 l/sek)

What depends on reaching an explosive mixture?

• - Free air volume in a closed container or room (depending on size and installations)
• - Tightness of the objects attacked (openings possibly masked, etc.)
• - Outflow quantity per second of the introduced gas (eg physical limitation of acetylene max 1 l / sec)

Which mixture is required for acetylene / oxygen?

A gas mixture below the LEL is not explosive and a gas mixture above the OEG is not explosive.

Acetylene has a LEL of 2.3% by volume, an OEG of 80% by volume, within this range, the gas mixture is explosive.

How can inflammable gases be made harmless?

• – Reduktion des Sauerstoffgehaltes im Raum, der geschützt werden soll
• – Chemische Inertisierung des brennbaren Gases durch Inertgas
• – Verbrennung des Gasgemisches, bevor die Gasmenge für eine energiereiche Explosion erreicht wird

In order to prevent an explosion caused by flammable gases, different methods are available:

• - Reduction of the oxygen content in the room to be protected
• - Chemical inerting of the combustible gas by inert gas
• - Combustion of the gas mixture before the gas quantity for a high-energy explosion is reached

The reduction of the oxygen content in the room is not possible in containers or premises and thus falls out of the choice.

The chemical inerting of the combustible gas is one way in which combustible gases can be rendered harmless, but the storage of the inert gas within the objects to be protected is often difficult (space problem).
Furthermore, the cost of inert gas is very high and the maintenance is expensive (leak test, weighing the container, etc.).
A prevention of the explosion is only possible as long as inert gas is available. (Limited guard time)

Combustion of the gas mixture is a very effective method of rendering the gas mixture harmless before the concentration of an explosion is sufficient to destroy the closed container or space.

The previously used methods for preventing blasting are dependent on the fact that a countermeasure is initiated on the basis of a detection of the gas concentration or detection of the composition of the atmosphere in the room.

Disadvantages of existing systems:

Detector for gas concentration or composition of the atmosphere in the room:

• - failure
• - pollution
• - deception
• - Reaction speed
• - aging
• - Required readjustment
• - Maintenance
• - Can all combustible gases be detected

Since the activation or initiation of countermeasures in these systems is dependent on the detection of the gas concentration or composition of the atmosphere in space, this represents a high hazard for non-functioning of such systems.

Introduced countermeasures:

• - space requirements of the containers (also attached outside)
• - Limited quantities (period of suppression)
• - Type of activation (pyrotechnic, mechanical)
• - Required maintenance (weighing, tightness)
• - Health and environmental compatibility of the countermeasures (inert gases)

In order to provide a sufficient protective window (in which an explosion is prevented), containers with antidote are necessary. Due to the today small z. As money and ticket vending machines installation of all components of these systems is very difficult and sometimes only outside the objects to be protected possible. This represents a high risk for manipulation and foreign influence by eventual perpetrators.

In systems that work with displacement (CO2, nitrogen, etc.), gases from the z. B. money and ticket vending machines to the outside (eg foyer) are displaced, which may eventually lead to an explosion outside the object.

The methods used to date require extensive expertise for installation and service and much too high installation costs. The cost of purchase, installation and maintenance are too high.

The object of the invention, however, is to provide a simple, effective system that prevents the use of as few sensors and electronics as possible, attacks with explosive gases on closed pores or premises for an unlimited period of time. No matter how long and how often flammable gases are introduced.

In addition, the detection of a deflagration or pressure change to the deposition of an alarm message.

As many as possible, independently controlled and guided via a control unit ignition modules that are distributed in the container or room, produce so-called. Sparks, the gases introduced, well before they reach a dangerous gas concentration (the destruction of the container or the spatiality can lead), fizzle.

This deflagration is detected by a sensor and forwarded as a signal.

The ignition modules are arranged evenly in the closed container or space, so that each 2 pieces are in the upper, middle and lower area.

Potential perpetrators should not be given the opportunity to open or destroy closed containers or premises by introducing explosive gases.
Furthermore, the signal should inform emergency services as early as possible, so that further steps can be taken.

By fuming the explosive gases, even before they reach a dangerous gas concentration, the risk to third parties and the damage to buildings and the containers or premises itself should be avoided because no more explosive gas can escape from the closed containers or premises.

The signal output upon detection of a change in pressure via the control unit can be issued as a silent alarm to increase the likelihood of the perpetrators still being caught in their work. The signal can also be used to trigger other alarm systems to disturb the perpetrators, to make the expected loot worthless, to make residents or residents alert, so that the perpetrators of your project.

The system components are installed completely inside the closed containers or premises in order to avoid manipulation or external influences.

The ignition modules are designed so that they have approximately 20 times the ignition energy, which in Normafall (MZE maximum ignition energy of 0.019 mJ for acetylene air mixtures sufficient) for the ignition of an acetylene air mixture is required.

Each individual ignition module works for itself, d. H. in each ignition module, the electronics for generating the spark is installed.

This means that if one ignition module fails, the other ignition modules will continue to operate autonomously.

• – jedes Zündmodul einzeln angesteuert wird
• – die tatsächliche Funktion (Funkenerzeugung) des Zündmodules vom Steuergerät überwacht werden kann

The ignition modules are connected to a trigger line and a monitoring line to the controller, so that

• - Each ignition module is controlled individually
• - The actual function (spark generation) of the ignition module can be monitored by the control unit

Due to the permanent monitoring of each individual ignition module, in the event of a fault, a message can be output or the system can be switched off. (Simultaneous failure of 50% corresponds to 3 ignition modules).

The ignition modules are encapsulated in a housing and thus protected against all environmental influences. The electrodes of the ignition modules are easily replaceable for service purposes.

Controller:

The control unit has the option of disarming or arming the explosion protection. (Switching on or off by eg door contact or integration into existing switching operations is possible.)

The control unit

• - serves to supply power to all sensors and components
• - controls and monitors the ignition modules (each one)
• - Each output and input to the ignition modules is executed individually in terms of hardware in order to achieve high redundancy (high system security)
• - outputs a fault message if required
• - gives a signal z. B. alarm message, control of other safety devices from
• - outputs the status of the system via an LED status display
• - is equipped with an emergency power supply

The 6 ignition modules work independently, each of which is monitored by sensors, so that the full functionality of the 6 ignition modules can be determined via the control unit. (Monitoring if sparks are actually generated).

• – Ausfall von 1 Zündmodul – System meldet Fehler, bleibt aber in Betrieb
• – Ausfall von 2 Zündmodulen – System meldet Fehler, bleibt aber in Betrieb
• – Ausfall von 3 Zündmodulen – System meldet Fehler und schaltet ab

The control unit reports failure of the ignition modules via a potential-free relay contact in the following manner:

• - Failure of 1 ignition module - System reports errors, but remains in operation
• - Failure of 2 ignition modules - System reports errors, but remains in operation
• - Failure of 3 ignition modules - System reports errors and shuts off

Pressure sensor:

The system is equipped with a pressure sensor which detects the pressure fluctuation caused by the deflagration of gases introduced.
After evaluation of this pressure fluctuation, the control unit provides an alarm signal via a potential-free relay contact.
The pressure sensor is used exclusively for the alarm message and in no way influences the autarkic function of the ignition modules.

The system is equipped with an emergency power supply to ensure a function (prevention of explosion) over a certain period of time, even in the event of a power failure, disconnection of the power supply.

The advantages of the system:

• - No problematic sensors for detecting the gas concentration or composition of the atmosphere in the room as a trigger of the countermeasures
• - unlimited protection (even when refilling)
• - Immediate deflagration of all flammable gases on the market, even before a leading to destruction gas mixture can arise
• - No displacement of the introduced gas to the outside
• - easy installation
• - low service and maintenance costs
• - Small footprint, no additional antidote container required
• - installation of all components inside the closed container or room, (no manipulation or external influence by attackers possible)
• - no adverse health or environmental remedies are used

• – dass im Inneren 6 autark funktionierende Zündmodule angebracht sind, und/oder
• – dass die 6 Zündmodule ständig oder in bestimmten Intervallen, gleichzeitig oder hintereinander Funken abgeben, und/oder
• – dass die 6 Zündmodule auf eine bestimmte Art und Weise im Inneren des zu schützenden Objektes angeordnet sind, und/oder
• – dass jedes Zündmodul autark arbeitet, d. h. mit eigener Elektronik zur Erzeugung des Zündfunkens, und/oder
• – dass jedes Zündmodul über das Steuermodul hardwaremäßig über einzelne Ausgänge angesteuert wird, und/oder
• – dass jedes Zündmodul über das Steuermodul hardwaremäßig über einzelne Eingänge überwacht wird, und/oder
• – dass die Verpuffung über einen Drucksensor registriert wird, und/oder
• – dass nach Verpuffung über einen Drucksensor ein Alarmsignal über einen potentialfreien Relaiskontakt vom Steuergerät ausgegeben wird, und/oder
• – dass das System über eine Notstromversorgung verfügt, und/oder
• – dass die Elektroden an den Zündmodulen austauschbar sind, und/oder
• – dass das eingeleitete brennbare Gas durch die Zündmodule verpufft wird, und/oder
• – dass die Zündmodule in regelmäßigen Abständen einen Funken erzeugen, und/oder
• – dass bei Ausfall von 50% der Zündmodule das System abgeschaltet wird, und/oder
• – dass bei Ausfall eines Zündmoduls eine Störmeldung abgegeben wird.
