Description

DEVICE FOR SECURING A CLOSED SPACE BY IDENTIFICATION

  The present invention relates to securing an enclosed space (for example: car parks, laboratories, and more generally all secure collective places) by identifying persons having access to it.

  The protected areas concerned by the present invention may have a personal vocation (apartments, individual houses, pavilions, car parks, etc.) as well as professional (offices, warehouses, factories, garages, sheds, etc.).

  At present, there are three main areas of electronic processes for the protection of closed premises.

  These areas are: CCTV (cameras, image recorders), access control (intercoms, digicodes, badges, biometrics) and anti-intrusion systems (alarms).

  CCTV is provided by cameras that monitor a defined space. Images are viewed directly and / or recorded. Its main disadvantage is that either human surveillance is essential to monitor a site, or the recorded images should be used to try to identify the perpetrator (s) but can not prevent it from perpetrating it; CCTV is not preventive.

  Access control systems are intended to physically prevent unauthorized persons from entering the premises by locking access (doors, grilles, barriers, ...). The buildings remain accessible provided that the means of unlocking the system (codes, keys, badges, biological impressions, etc.) are available. Its disadvantage is that its action is limited and that, if an intruder succeeds in entering the premises (passage through the roof, through the window, with an authorized person, ...), the access control is no longer in place. able to provide any protection.

  As for anti-intrusion systems, their purpose is to secure an enclosed space, not by protecting access, but by detecting an unwanted human presence (when the system is running) that will trigger a protection system. The detection is provided by sensors arranged in the enclosure (opening sashes, movements, broken glass ...). Protection is however provided by deterrence (horns, sirens, smoke, ...), and / or the transmission of a telephone alert to an intervention agency (telemonitoring, security company, police, .. .). Even though there are alarm panels that also manage access control, all the current systems present a major flaw: They are not able to automatically identify whether a person is authorized or not, to enter the system. the locals, the residents. All require human intervention to be armed or disarmed (on / off), so there is no system capable of continuous operation while managing a large flow of people.

  Consequently, to date, there are no autonomous systems capable of ensuring the real-time security of premises in the presence of persons inside these same premises. In other words, none of the existing systems can provide reliable continuous protection and distinguish between the detection of an intruder and that of an authorized person (distinction of friends or enemies).

  An object of the present invention is therefore to provide an installation for securing closed sites by an anti-intrusion system, capable of distinguishing between an intruder and an authorized person.

  Another object of the present invention is to provide an installation for securing closed sites whose design allows continuous operation of the system.

  Another object of the present invention is to provide an installation for securing closed sites whose design allows rapid identification, and thus to manage a large flow of people.

  For this purpose, the object of the invention is to secure a closed space of the aforementioned type (car parks, laboratories, sensitive sites, etc.), characterized in that an authorized person carries an identifier (transponders communicating with each other). by radio, magnetic badges, ...) which will automatically allow the inhibition of an alarm system, which will have been previously triggered by presence sensors, judiciously concealed inside the premises to be protected.

  The invention will be better understood on reading the following description, with reference to the appended drawings in which: FIG. 1 represents an example of an application for securing an enclosed space and FIG. 2 schematically represents the operation a system for securing a confined space according to the invention, according to a first embodiment.

  - Figure 3 schematically shows the operation of a securing system of a closed space according to the invention, according to a second possible embodiment 35.

  The invention therefore relates, as mentioned above, the securing of a closed space of which Figure 1 represents an example; the number of rooms and their provisions is not decisive for its proper functioning but imposes an appropriate organization of the various elements that compose it.

  FIG. 2 represents the operating diagram of said system which can be described as follows: When an individual enters a secure space, it is detected by a presence detector 35 which transmits the detection information by activating the detector. input 8b of the comparator module 8 through which its output is connected.

  In the same time interval, the individual entering this secure space must be in possession of its identification process 1 (transponders communicating via radio, magnetic badges, etc.). It must identify itself (magnetic badges, ...) or be automatically identified (transponders communicating by radio, ...) by the identification receiver 2 within a given time and determined by an adjustable delay (called delay time). trigger inhibition, thus adjusting one of the parameters of the general system sensitivity), on the comparator module 8.

  The identification receiver 2 transmits the identification information by activating the input 8a of the comparator module 8 by which its output is connected, thus disarming the comparator module 8. The comparator module 8 then does not activate its output 8c, not triggering the protection system 9 and, resets at the end of an adjustable delay (called reset time) thus adjusting one of the parameters of the general sensitivity of the system. In general, the comparator module 8 activates its output 8c - which will trigger the protection system 9 provided by deterrence (buzzers, sirens, smoke, ...), and / or the transmission of a telephone alert to an intervention organ (telemonitoring, guarding company, police, etc.) if the input 8b of this module has been activated, and the other input 8a has not been at the end of an adjustable delay ( said trigger inhibit timer, thereby adjusting one of the general system sensitivity parameters), thus no longer inhibiting the triggering of the protection system 9.

  The number of presence detectors 3, identification methods 1, identification receivers 2, and the number of comparator modules 8 and protection systems 9 are not limited in an installation.

  All these organs can be multiplied as many times as necessary and, assigned to several different comparator modules 8 and / or protection systems 9 different, in order to be able to compartmentalize a secure closed space in several secure areas - within this same space associated with one or more groups of identification systems 1 only allowed within that same zone.

  FIG. 3 represents the operating diagram of said system, in the case where the passage of cables inside a secure closed space is compromised or difficult (parking, etc.), which calls for the use of a wireless transmission type wireless, and whose operation can be described as follows: When an individual enters a secure space, it is detected by a presence detector 3 40 which transmits the information to a transmitter 4. This transmitter 4 is of wireless type, therefore wireless, with a unique identification code. The detection information thus relayed is picked up by a receiver 7 which, after having identified the code of the transmitter thus guaranteeing a security in the wireless transmission, will transmit the detection information and then activate the input 8b of the module comparator 8 through which its output is connected.

  In the same time interval, the individual entering this secure space must be in possession of its identification process 1 (transponders communicating via radio, magnetic badges, etc.). It must identify itself (magnetic badges, ...) or be automatically identified (transponders communicating by radio, ...) by the identification receiver 2 within a given time and determined by an adjustable delay (called delay time). trigger inhibition, thus adjusting one of the parameters of the general system sensitivity), on the comparator module 8.

  The identification receiver 2 transmits the identification information to a transmitter 5 of wireless type, therefore wireless, which also has a unique identification code. The relaying information thus relayed is picked up by a receiver 6 which, after having identified the code of the transmitter thus guaranteeing a security in the wireless transmission, will transmit the identification information and then activate the input 8a. of the comparator module 8 through which its output is connected, thus disarming the comparator module 8.

  The comparator module 8 then does not activate its output 8c, does not trigger the protection system 9 and resets after an adjustable delay (called reset time) thus adjusting one of the parameters of the general sensitivity of the system.

  In general, the comparator module 8 activates its output 8c which will trigger the protection system 9 provided by deterrence (horns, sirens, smoke, ...), and / or the transmission of a telephone alert to an intervention organ (telemonitoring, guarding companies, police, etc.) if the input 8b of this module has been activated, and the other input 8a has not been at the end of an adjustable delay ( said trigger inhibit timer, thereby adjusting one of the general system sensitivity parameters), thus no longer inhibiting the triggering of the protection system 9.

  The number of presence detectors 3, identification methods 1, identification receivers 2, transmitters 4 and 5, receivers 6 and 7, as well as the number of comparator modules 8 and protection system 9 are not not limited in an installation.

  All these organs can be multiplied as many times as necessary and, assigned to several different comparator modules 8 and / or protection systems 9 different, in order to be able to compartmentalize a secure closed space in several secure areas - within this same space associated with one or more groups of identification systems 1 only allowed within that same zone.
