Description

The field of the invention is that of the design and manufacture of door equipment, and more specifically of equipment designed to counter intrusions.

More specifically, the invention relates to an anti-intrusion system comprising a mechanical cylinder capable of being opened by a key, and additional means for reversibly locking the cylinder.

Conventional door locking devices may include a lock coupled to a door, the lock incorporating a locking bolt intended to cooperate with a strike plate located on a frame of the door, the bolt being, for example, actuated by the cooperation of a key in a mechanical cylinder.

In order to improve the security of this type of device, various developments have sometimes sought to improve the key-cylinder combination, or sometimes sought to improve the accessories of these locking devices.

Reversible locking means for mechanical cylinders have also been proposed. These electromechanical locking means make it possible to render a key compatible with a mechanical cylinder unusable when these locking means are active, i.e. when they exert an action on the cylinder preventing its actuation using the compatible key. An electronic instruction to a computer unit controlling locking means, resulting from electronic authentication, is for example necessary in order to deactivate these locking means. One problem lies in the need for a continuous power supply to the locking means, and the consequences of a power failure.

The invention aims to overcome the drawbacks of the prior art.

More specifically, the invention aims to propose a more secure anti-intrusion system than that proposed by the prior art.

The invention also aims to provide such a system which makes it possible to overcome the consequences of a power failure on the electromechanical elements of such anti-intrusion systems.

These objectives, as well as others which will appear subsequently, are achieved thanks to the invention which relates to an anti-intrusion system comprising:

• a door,
• a lock associated with the door, having a mechanical cylinder capable of being driven by an authorized key to move mechanical locking means of the door in the closed position from a locked position to an unlocked position, or vice versa,
• electrically powered reversible cylinder locking means,
• autonomous electrical power supply means carried by the door and capable of electrically supplying the locking means, the autonomous electrical power supply means comprising at least one rechargeable electric battery,

• characterized in that the door also integrates a computer unit configured for:
  • detect a power supply to the locking means by the autonomous power supply means,
  • measure the autonomy of autonomous electrical power supply means,
  • memorize a limit threshold of autonomy corresponding to a predetermined threshold of discharge of the autonomous electrical supply means,
• and in that the locking means are configured to be deactivated when the limit threshold is reached, so as to allow the cylinder to be driven by an authorized key, and in that the door is mounted on a frame electrically connected to a general power supply, the frame having primary electrical connection means and the door having secondary electrical connection means intended to be in electrical contact with the primary electrical connection means when the door is closed,
• and in that the computer unit is configured to:
  • detect a power supply by secondary means of connection and,
  • in the event of detection of a power supply by the secondary connection means, make the autonomous power supply means inactive,
  • in the event of detection of a lack of power supply by the secondary connection means, activate the autonomous power supply means; and in that the door incorporates long-distance communication means capable of communicating with a computer device remote from the door,
• and in that it comprises a door closed position sensor connected to the computer unit to transmit to it a door closed position signal, and in that the computer unit is configured to send a notification to the remote computer device in the event of detection of an absence of electrical power supply by the secondary connection means while it receives a closed position signal.

Such a system makes it possible to maintain the level of security it provides thanks to the locking means, for the period of time corresponding to the remaining autonomy autonomous power supply means up to the limit threshold, threshold where the deactivation of the locking means prevents the door from being unopenable subsequently.

This optimizes the system's ability to lock the mechanical cylinder and prevent intrusion during a power outage, for as long as possible before deactivating the cylinder's locking means.

By mounting the door on a frame electrically connected to a general power supply, and by configuring the computer unit ad hoc, it is possible to supply the electrical components of the anti-intrusion system with priority from a source other than the autonomous power supply means, in order to preserve and/or recharge them.

Long-distance communication means capable of communicating with a computing device remote from the door allow for the consultation of system-related information from the remote computing device, or the transmission of system-related information to the remote computing device.

The remote computing device can be a computer designed to remotely operate the system, or a smartphone.

Thanks to the closed door position sensor connected to the computer unit and the computer unit's settings, users or a manager can be made aware of a power outage leading to the use of autonomous power supply resources.

• alarme ;
• sonnette ;
• écran ;
• moyens de communication courte distance ;
• lecteur de badge d'accès.

According to preferred variants, the door incorporates additional electrical equipment, among the following equipment:

• alarm ;
• doorbell;
• screen ;
• short-distance means of communication;
• access badge reader.

The system can then offer various additional functions enriching the user experience, as well as the security it provides.

For example, a badge can be used to simply disable the locking means to allow the door to be opened using a compatible key.

According to another example, short-distance communication means can also be used to deactivate the locking means, in particular using a smartphone on which an application with access rights is installed.

• mémoriser un seuil intermédiaire d'autonomie des moyens d'alimentation électrique autonome ;
• désactiver l'alimentation des équipements électriques additionnels lorsqu'une énergie résiduelle des moyens d'alimentation électrique autonome atteint ou descend en dessous du seuil intermédiaire d'autonomie.

In this case, advantageously, the computer unit is configured to:

• memorize an intermediate threshold of autonomy of the autonomous electrical supply means;
• deactivate the power supply to additional electrical equipment when residual energy from the autonomous electrical supply means reaches or falls below the intermediate autonomy threshold.

This makes it possible to extend the door securing time using active locking means, while allowing additional electrical equipment to remain operational until the intermediate autonomy threshold is reached.

Preferably, the limit threshold corresponds to a completely discharged state of the autonomous electrical supply means.

• mémoriser un seuil spécifique d'autonomie des moyens d'alimentation électrique autonome ;
• désactiver l'alimentation des moyens de communication à longue distance lorsqu'une énergie résiduelle des moyens d'alimentation électrique autonome atteint ou descend en dessous du seuil spécifique d'autonomie.

In this case, advantageously, the computer unit is configured to:

• memorize a specific threshold of autonomy of the autonomous electrical supply means;
• deactivate the power supply to the long-distance communication means when the residual energy of the autonomous power supply means reaches or falls below the specific autonomy threshold.

Such long-distance communication methods can be particularly energy-intensive. Consequently, it is particularly advantageous to deactivate them with a specific autonomy threshold, especially quickly after the interruption of a mains power supply.

• réactiver temporairement les moyens de communication à longue distance ;
• émettre une notification relative au seuil atteint par le biais des moyens de communication à longue distance ;
• désactiver les moyens de communication à longue distance immédiatement après l'émission de la notification.

• temporarily reactivate long-distance means of communication;
• issue a notification of the threshold reached through long-distance means of communication;
• disable long-distance communication facilities immediately after the notification is issued.

In this way, a manager is informed of each autonomy threshold reached by the autonomous power supply means.

Advantageously, the computer unit is configured to emit the autonomy of the autonomous power supply means with the notification.

• la figure 2 est une représentation schématique du système.

Other characteristics and advantages of the invention will appear more clearly on reading the following description of a preferred embodiment of the invention, given as an illustrative and non-limiting example, and the appended drawings among which:

• there Figure 1 is a schematic representation of a door of an anti-intrusion system according to the invention;
• there Figure 2 is a schematic representation of the system.

There Figure 1 illustrates a part of the anti-intrusion system according to the invention, and the Figure 2 illustrates the integration of system components on Gate 1.

This anti-intrusion system comprises a door 1 mounted movably in a frame 11 between a position for closing a passage defined by the frame 11 and a position for releasing the passage.

The system also includes a lock 2 associated with door 1.

According to the present embodiment, the lock 2 takes the form of a strip installed as an applique on the door 1 and its frame 11. More precisely, the lock 2 has a first part 201 carried by the door 11, and a second part 202 carried by the frame 11.

• des moyens mécaniques de verrouillage 22 de la porte 1 en position fermée ;
• un cylindre 21 mécanique configuré pour permettre, à l'aide d'une clé compatible, l'entrainement des moyens mécaniques de verrouillage 22 d'une position verrouillée à une position déverrouillée, et inversement.

Lock 2 also includes:

• mechanical means 22 for locking the door 1 in the closed position;
• a mechanical cylinder 21 configured to allow, using a compatible key, the driving of the mechanical locking means 22 from a locked position to an unlocked position, and vice versa.

The locking means 22 are, according to the present embodiment, locking pins 221 intended to protrude from the first part 201 of the lock, and to be inserted into strike plates presented by the second part 202 of the lock 2.

The lock 2 further comprises a handle, allowing the actuation of a beveled bolt to open the door 1 after unlocking the locking means 22.

Of course, the locking means may take a form other than mechanical means, for example magnetic means.

The anti-intrusion system also includes means of reversible locking 3 of the mechanical cylinder 21.

These locking means 3 are of the electrical type, and are therefore electrically powered.

The locking means 3 are configured to be able to adopt either an active state in which they block the capacity of the cylinder 21 to drive the locking means 22 even when a compatible key is used, or a deactivated state in which a compatible key allows the cylinder 21 to be operated and the position of the locking means 22 to be changed.

The locking means 3 comprise, for example, a stopper and an electric actuator.

The stopper is reversibly movable between an active position in which it prevents actuation of the cylinder 21, for example the rotation of a cylinder bit, and an inactive position in which the stopper releases rotation of the bit.

According to a particular embodiment, the stopper comprises a return spring which permanently urges the stopper towards its inactive position.

The electric actuator is associated with the stopper so that, when the electric actuator is supplied with electricity, it causes the stopper to move to its active position.

The locking means 3 further comprise a control unit which controls the electric actuator, in particular by supplying it with electricity or by suspending its electricity supply. The receipt of an unlocking instruction by the control unit causes the suspension of the electricity supply to the electric actuator, and thus the passage of the stop from its active position to its inactive position under the effect of its return spring.

According to the present embodiment, door 1 integrates additional electrical equipment.

• une alarme 61 ;
• une sonnette 62 ;
• un écran 63 ;
• des moyens de communication courte distance 64 ;
• au moins un lecteur de badge d'accès 65.

These additional electrical equipments include the following:

• an alarm 61;
• a bell 62;
• a 63 screen;
• short-distance communication means 64;
• at least one 65 access badge reader.

The alarm 61 corresponds to an electronic module designed to trigger an alert, following the reception of an attempted intrusion signal from an electronic component of the anti-intrusion system, or from another compatible external electronic element. The alarm 61 comprises for example a loudspeaker capable of emitting an audible alert, or means for controlling a loudspeaker of the anti-intrusion system to emit an audible alert.

The bell 62 comprises an actuator located on an external face of the door 1, and a loudspeaker capable of emitting a ringing tone, or means for controlling a loudspeaker of the anti-intrusion system to emit a ringing tone.

The screen 63 is intended to display information about the anti-intrusion system, and to allow actions to be performed on the system. For example, the screen 63 may be touch-sensitive and allow an identification code to be entered.

The short-distance communication means 64 correspond, according to the present embodiment, to electronic components implementing a telecommunications standard allowing the bidirectional exchange of data over short distances using UHF radio waves on a predetermined frequency band. For example, the standard implemented is that designated by the registered trademark Bluetooth.

According to another embodiment, the short-distance communication means 64 may be of the type allowing near-field communication, often designated by the English acronym NFC.

It is conceivable that several technologies will be implemented simultaneously by short-distance communication means 64, including Bluetooth and NFC.

The access badge reader 65 is designed to enable the identification of predetermined badges carrying identifiers authorized by the anti-intrusion system.

The access badge reader 65 may be designed to read magnetic badges, RFID badges, or other types of badges. For example, the access badge reader 65 may be associated with the short-distance communication means 64 in order to allow the reading of badges implementing this type of communication protocol.

According to other possible embodiments, door 1 could not integrate any of this additional electrical equipment, or only one, or even only part of this equipment.

Gate 1 also integrates long-distance communication means 66 capable of communicating with a computer device remote from gate 1.

The remote computing device can be a computer station or a smartphone.

Door 1 also integrates a computer unit 5 coupled with the locking means 3, the additional electrical equipment, and the long-distance communication means 66 in order to operate and control them.

The locking means 3, the additional electrical equipment, and the long-distance communication means 66, and the computer unit 5 each require a power supply.

• une alimentation électrique générale 42 ;
• des moyens d'alimentation électrique autonome 41.

For this purpose, according to the present embodiment, the anti-intrusion system comprises an electrical power supply system comprising:

• a general power supply 42;
• autonomous power supply means 41.

As mentioned previously, door 1 is mounted on a frame 11.

This sleeper 11 is electrically connected to the general power supply 42. This general power supply 42 corresponds to a connection to the mains in order to have a continuous power supply, except in the event of a power failure.

The frame 11 then has primary electrical connection means 421 and the door 1 has secondary electrical connection means 422 intended to be in electrical contact with the primary electrical connection means 421 when the door is closed.

The primary connection means 421 and the secondary connection means 422 concretely take the form of electrical terminals coming into contact with each other when the door 1 is closed.

The autonomous electrical power supply means 41 are carried by door 1.

These autonomous electrical power supply means 41 are in particular capable of electrically supplying the locking means 3.

The autonomous electrical power supply means 41 comprise at least one electric battery.

As detailed below, the locking means 41 are configured to be deactivated when a limit threshold S1 of autonomy of the electric battery is reached, so as to authorize driving of the cylinder 21 by an authorized key.

The electric battery is preferably rechargeable. When the general power supply 42 is active (door 1 closed), the electric battery is recharged and is maintained at its optimal state of charge.

The autonomous electrical power supply means 41 also comprise a subsystem for determining the state of charge of the electric battery.

This determination subsystem makes it possible to establish the residual energy level of the electric battery in order to determine autonomy.

It is possible to envisage an embodiment in which the electrical power supply system would only comprise autonomous electrical power supply means 41. In this case, the autonomous electrical power supply means 41 may comprise a generator associated with an element driven in mobility of the door 1 when it opens, in order to produce electricity each time the door 1 is actuation, and to recharge the electric battery of the autonomous electrical power supply means 41.

The system also includes a closed position sensor 67 of the door 1 connected to the computer unit 5 to transmit to it a closed position signal of the door 1.

This closed position sensor 67 is notably distinct from the secondary connection means 422.

The computer unit 5 comprises processing means, an electronic memory, and is coupled to the electronic and electromechanical components of the anti-intrusion system in order to detect events, measure parameters, carry out monitoring, and control these components.

As detailed below, the computer unit 5 is programmable and is designed to memorize, that is to say store in its electronic memory, autonomy thresholds of the autonomous electrical power supply means 41, and more precisely of the electric battery.

• un seuil limite S1 ;
• un seuil intermédiaire S2 d'autonomie, supérieur au seuil limite S1 ;
• un seuil spécifique S3 d'autonomie, également supérieur au seuil limite S1, et préférentiellement supérieur au seuil intermédiaire S2.

These autonomy thresholds include, among others:

• a limit threshold S1;
• an intermediate threshold S2 of autonomy, higher than the limit threshold S1;
• a specific autonomy threshold S3, also higher than the limit threshold S1, and preferably higher than the intermediate threshold S2.

More precisely, the computer unit 5 is configured to detect a power supply to the locking means 3 by the autonomous power supply means 41 integrated into the door 1.

It is recalled that, according to one possible embodiment, the locking means 3 are powered only by the autonomous electrical power supply means 41 integrated into the door 1 (i.e. in the absence of any other power supply means such as a general electrical power supply). However, according to another possible embodiment, this time including a general electrical power supply, the electrical power supply of the locking means 3 by the autonomous electrical power supply means 41 only occurs in the event of a power cut by the general electrical power supply 42.

• mesurer l'autonomie des moyens d'alimentation électrique autonome 41,
• mémoriser le seuil limite S1 de l'autonomie,
• désactiver les moyens de condamnation 3 lorsque le seuil limite S1 est atteint, de façon à autoriser un entraînement du cylindre 21 par une clé autorisée.

In any case, computer unit 5 is configured to:

• measure the autonomy of autonomous electrical power supply means 41,
• memorize the S1 limit threshold of autonomy,
• deactivate the locking means 3 when the limit threshold S1 is reached, so as to authorize driving of the cylinder 21 by an authorized key.

The limit threshold S1 corresponds to a predetermined threshold for discharging the autonomous electrical supply means 41 integrated into the door 1.

According to the preferred embodiment, the limit threshold S1 corresponds to a completely discharged state of the autonomous electrical supply means 41.

• mémoriser le seuil intermédiaire S2 d'autonomie des moyens d'alimentation électrique autonome 41 ;
• désactiver l'alimentation des équipements électriques additionnels lorsqu'une énergie résiduelle des moyens d'alimentation électrique autonome 41 atteint ou descend en dessous du seuil intermédiaire S2 d'autonomie.

Computer Unit 5 is also configured to:

• memorize the intermediate threshold S2 of autonomy of the autonomous electrical supply means 41;
• deactivate the power supply to the additional electrical equipment when residual energy of the autonomous electrical supply means 41 reaches or falls below the intermediate autonomy threshold S2.

• mémoriser le seuil spécifique S3 d'autonomie des moyens d'alimentation électrique autonome 41 ;
• désactiver l'alimentation des moyens de communication à longue distance 66 lorsqu'une énergie résiduelle des moyens d'alimentation électrique autonome 41 atteint ou descend en dessous du seuil spécifique S3 d'autonomie.

Computer unit 5 is still configured for:

• memorize the specific threshold S3 of autonomy of the autonomous electrical supply means 41;
• deactivate the power supply of the long-distance communication means 66 when residual energy of the autonomous power supply means 41 reaches or falls below the specific autonomy threshold S3.

The autonomy thresholds, and the deactivations they cause, make it possible to maximize the protection offered by the anti-intrusion system.

• seuil spécifique S3 = 75% de la capacité maximale de la batterie électrique des moyens d'alimentation électrique autonome 4 ;
• seuil intermédiaire S2 = 50% de la capacité maximale de la batterie électrique des moyens d'alimentation électrique autonome 4 ;
• seuil limite S1 = 25% de la capacité maximale de la batterie électrique des moyens d'alimentation électrique autonome 4.

According to the example illustrated on the Figure 2 , the thresholds are as follows:

• specific threshold S3 = 75% of the maximum capacity of the electric battery of the autonomous electrical supply means 4;
• intermediate threshold S2 = 50% of the maximum capacity of the electric battery of the autonomous electrical supply means 4;
• limit threshold S1 = 25% of the maximum capacity of the electric battery of the autonomous electrical supply means 4.

Other thresholds and other threshold values are conceivable. In particular, threshold values may be calculated and stored by the computer unit 5 using other parameters of the system at the time of loss of power from the general power supply 42.

In this example, as long as the autonomous electrical power supply means 41 have not reached the specific threshold S3 (electric battery charge between 75% and 100%), the system keeps all of its electronic systems active.

The system can, in particular, notify managers or users of the incident via long-distance communication means 66, which are always active.

Indeed, the computer unit 5 is configured to send a notification to the remote computer device in the event of detection of an absence of electrical power supply by the secondary connection means while it receives a closed position signal, which corresponds to a case in which the autonomous electrical power supply means 41 are used.

When the autonomous power supply means 41 reach the specific threshold S3 (electric battery charge at 75%), the computer unit 5 deactivates the long-distance communication means 66. This corresponds to a first limited action state of the anti-intrusion system. This first limited action state provides energy savings, but allows the other functionalities of the system to be kept active, including the locking means 3.

When the autonomous power supply means 41 reach the intermediate threshold S2 (electric battery charge at 50%), the computer unit 5 deactivates the additional electrical equipment. This corresponds to a second limited action state of the anti-intrusion system. This second limited action state improves energy saving, but allows the locking means 3 to remain active.

Finally, when the autonomous electrical supply means 41 reach the limit threshold S1 (charge of the electric battery at 25%) of the autonomy, the locking means 3 are deactivated, subsequently authorizing driving of the cylinder 21 by an authorized key.

As mentioned previously, other thresholds may be put in place.

For example, only part of the additional electrical equipment can be deactivated with the intermediate threshold S2, while the short-distance communication means 64 and the access badge reader 65 remain active. Another threshold, prior to the limit threshold S1, causes the deactivation of this residual additional electrical equipment. This allows authentication to be carried out by access badge or by means of the short-distance communication means to temporarily deactivate the locking means 3 in order to open the door 1.

• détecter une alimentation électrique par les moyens secondaires de connexion 422 et,
• en cas de détection d'une alimentation électrique par les moyens secondaires de connexion 422, rendre inactifs les moyens d'alimentation électrique autonome 41,
• en cas de détection d'une absence d'alimentation électrique par les moyens secondaires de connexion 422, activer les moyens d'alimentation électrique autonome 41.

Computer Unit 5 is also configured to:

• detect a power supply by the secondary connection means 422 and,
• in the event of detection of a power supply by the secondary connection means 422, render the autonomous power supply means 41 inactive,
• in the event of detection of a lack of electrical power supply by the secondary connection means 422, activate the autonomous electrical power supply means 41.

Immediate recharging of the autonomous electrical power supply means 41 is then carried out, preventing them from discharging further.

The computer unit 5 is advantageously configured to temporarily reactivate the long-distance communication means 66 when a threshold is reached, and to transmit a notification to the remote computer device via these long-distance communication means 66.

This notification is intended in particular to warn a user or operator of the system of the crossing of thresholds.

Furthermore, the computer unit 5 is configured to transmit the remaining autonomy of the autonomous power supply means 41 with the notification.

Following the issuance of the notification, the long-distance communication means 66 are directly deactivated, again, in order to save the residual energy of the electric battery.

• réactiver temporairement les moyens de communication longue distance 66 ;
• émettre la notification relative au seuil atteint par le biais des moyens de communication longue distance 66 ;
• désactiver les moyens de communication longue distance 66 immédiatement après l'émission de la notification.

In other words, the computer unit 5 is configured, in the event of reaching at least one of the stored thresholds (the intermediate threshold for example), to:

• temporarily reactivate long-distance communication means 66;
• issue the notification relating to the threshold reached through long-distance communication means 66;
• disable long-distance communication facilities 66 immediately after the notification is issued.

The computer unit 5 is finally configured to reactivate long-distance communication means 66 in the event of detection of a new power supply by the secondary connection means 422. Long-distance communication between the computer unit 5 and a remote computer device, in particular that of a manager, is then possible. The computer unit 4 can in particular issue a notification forming a situation report including in particular the events that have occurred as well as their time stamps.

The invention forms an autonomous anti-intrusion system that adapts to the residual energy of the autonomous power supply means 41 to guarantee the security of an area. This system maximizes the time window during which it has the capacity to send information to its manager, and maintains security for an acceptable time before a possibility of intrusion.

Thanks to the anti-intrusion system, it is not possible to use a mechanical key or break the cylinder to open the door during a power outage, before the locking means are deactivated. However, the system allows this function to be released when all its energy has disappeared, allowing its manager, after an acceptable security period, to still be able to use his mechanical key.
