Description

DEVICE FOR SECURING A CLOSED SPACE BY IDENTIFICATION
The present invention relates to securing an enclosed space (for example:
parkings, laboratories, and more generally all secure collective places) by identification of people having permission to access it.

The protected environments concerned by the present invention may also have a vocation personal (apartments, houses, pavilions, car parks ...), as professional (offices, warehouses, factories, garages, sheds ...).
At present, there are three major areas of electronic processes having for object protection of closed places.
These areas are: CCTV (cameras, image recorders), the access control (intercoms, digicodes, badges, biometrics) and anti-intrusion systems (Alarms).
CCTV is provided by cameras that monitor a space defined. Images are viewed directly and / or recorded. Its main drawback is that, be a Human monitoring is essential to monitor a site, or saved images should be used to try to identify the perpetrator (s) of a wrongdoing, but can not in no way prevent him from perpetrating it; CCTV is not preventive.
Access control systems are intended to physically prevent no people authorized to enter the premises by locking the doors (doors, grids, barriers, ...). The buildings remain accessible provided that the means of unlocking the system (codes, keys, badges, biological footprints ...). Its disadvantage is that his action is limited and if an intruder managed to enter the premises (passing through the roof, through the window, with an authorized person, ...), access control is no longer able to ensure any protection.
As for anti-intrusion systems, their purpose is to secure a space closed, not in protecting access, but detecting an unwanted human presence (when the system is running) that will trigger a protection system. Detection is provided by sensors arranged in the enclosure (opening of opening, movements, breakage of glass ...).
Protection is in on the other hand by deterrence (horns, sirens, fumigants ....), and / or transmission of a telephone alert to an intervention agency (telesurveilleurs, society of guarding, police, ...). Even if there are central alarms managing also control all the current systems present a major flaw: They do not are not able to automatically identify whether a person is authorized or not, to penetrate in the places.
All require human intervention to be armed or disarmed (on / off), so that There is no system capable of running continuously while managing a important flow of people.

-2-As a result, to date, there are no autonomous systems capable of to ensure in real time the security of the premises in the presence of people inside these same local.
In other words, none of the existing systems can reliable protection and distinguish between the detection of an intruder and that of a authorized person (distinguish friends or enemies).

An object of the present invention is therefore to propose an installation for secure sites closed by an anti-intrusion system, able to distinguish between a intruder and a person authorized.
Another object of the present invention is to propose an installation for secure sites closed, whose design allows continuous operation of the system.

Another object of the present invention is to propose an installation for secure sites closed, whose design allows for quick identification, and thus to manage a significant flow of people.

For this purpose, the object of the invention is the securing of a closed space of the type aforementioned (car parks, laboratories, sensitive sites, etc.), characterized by the fact that a person authorized door on it an identifier (Transponders communicating via radio, badges magnetic, ...) that will automatically allow the inhibition of an alarm system, which has been beforehand triggered by presence sensors, wisely concealed inside premises to protect.

The invention will be better understood on reading the following description, in reference to the drawings annexed in which:

FIG. 1 represents an example of an application for securing a space closed and FIG. 2 schematically represents the operation of a system of securing a confined space according to the invention, according to a first embodiment of réaiisation.

FIG. 3 schematically represents the operation of a system of securing a closed space according to the invention, according to a second mode realization possible.

The invention therefore relates, as mentioned above, to the securing of a enclosed space whose Figure 1 represents an example; the number of rooms and their provisions not being decisive for its good functioning but imposes a suitable organization some issues elements that compose it.

-3-FIG. 2 represents the operating diagram of said system which can be describes the following way:
When an individual enters a secure space, he is detected by a presence detector 3 which transmits the detection information by activating the input 8b of the module 8 comparator which its output is connected.
In the same time interval, the individual entering this space secure must be in possession of its identification process 1 (Transponders communicating with hertzian way, magnetic badges, ...). He must identify himself (magnetic badges, ...) or to be automatically identified (Transponders communicating over the air, etc.) by the identification receiver 2 within a specified time and determined by an adjustable delay (called inhibition delay trigger, thus adjusting one of the sensitivity parameters system), on the comparator module 8.
The identification receiver 2 transmits the identification information by activating entry 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, not triggering the system of protection 9 and, resets at the end of an adjustable delay (said time delay of rearming) 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 system protection 9 provided by deterrence (sounders, sirens, fumigants, ...), and / or transmission of a telephone alert to an intervention agency (telesurveilleurs, society of guarding, police, ...) - only if the input 8b of this module has been activated, and that the other entry 8a does the step was at the end of an adjustable delay (called delay inhibition of trigger, thus adjusting one of the parameters of the general sensitivity of the system), thus no longer inhibiting the triggering of the protection system 9.
The number of presence detectors 3, identification methods 1, receptors identification number 2, as well as the number of comparator modules 8 and 9 protection are not limited in a facility.
All these organs can be multiplied as many times as necessary and, affected on several different comparator modules 8 and / or different protection systems 9, in order to compartmentalize a secure closed space into multiple secure areas - to inside this same space - associated with one or more groups of identification systems 1 only allowed inside this same area.

FIG. 3 represents the operating diagram of said system, in the case where the passage of cables inside a secure enclosed space is compromised or difficult (parking, ...), which solicits the use of a wireless transmission of the wireless type, and whose functioning can be described as follows:
When an individual enters a secure space, he is detected by a presence detector 3 which transmits the information to a transmitter 4. This transmitter 4 is of type wireless, so without wires,

-4-with a unique identification code. The detection information thus relayed is picked up by a receiver 7 which, having identified the transmitter code guaranteeing so security in the wireless transmission, will transmit detection information and activate then entry 8b of comparator module 8 by which its kind is connected.
In the same time interval, the individual entering this space secure must be in possession of its identification process 1 (Transponders communicating with hertzian way, magnetic badges, ...). He must identify himself (magnetic badges, ...) or to be automatically identified (Transponders communicating over the air, etc.) by the identification receiver 2 within a specified time and determined by an adjustable delay (called inhibition delay trigger, thus adjusting one of the sensitivity parameters system), on the comparator module 8.
The identification receiver 2 transmits the identification information to a transmitter 5 of type wireless, therefore wireless, which also has a unique identification code.
information identification relay is received by a receiver 6 which, after having identified the code of the transmitter thus guaranteeing security in the wireless transmission, will transmit the idenfification information and aetiver then the input 8a of the module comparator 8 by which his output is connected, thus disarming the comparator module 8.
The comparator module 8 then does not activate its output 8c, not triggering the system of protection 9 and, resets at the end of an adjustable delay (said time delay of rearming) 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 system protection 9 provided by deterrence (horns, sirens, fumigants, ...), and / or transmission of a telephone alert to an intervention agency (telemonitoring companies, guarding, police, ...) - only if the input 8b of this module has been brought up, and that the other entry 8a does the step was at the end of an adjustable temporisafion (called delaying inhibition of trigger, thus adjusting one of the parameters of the general sensitivity of the system), thus no longer inhibiting the triggering of the protection system 9.
The number of presence detectors 3, identification methods 1, receptors 2, transmitters 4 and 5, receivers 6 and 7, as well as the number of modules comparators 8 and protection system 9 are not limited in a installation.
All these organs can be multiplied as many times as necessary and, affected on several different comparator modules 8 and / or different protection systems 9, in order to compartmentalize a secure closed space into multiple secure areas - to inside this same space - associated with one or more groups of identification systems 1 only allowed inside this same area.
