Description

Title of the invention: Energy-saving anti-intrusion system

[0001] The field of the invention is that of the design and manufacture of door equipment, and more specifically of equipment designed to counter intrusions.

[0002] 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.

[0003] Conventional door closing 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 door frame, the bolt being, for example, actuated by the cooperation of a key in a mechanical cylinder.

[0004] 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.

[0005] Reversible locking mechanisms for mechanical cylinders have also been proposed. These electromechanical locking mechanisms render a key compatible with a mechanical cylinder unusable when the locking mechanisms are active, that is, when they exert an action on the cylinder preventing it from being operated with the compatible key. For example, an electronic command to a computer unit controlling the locking mechanisms, resulting from electronic authentication, is necessary to deactivate these locking mechanisms. One issue lies in the need for a continuous power supply to the locking mechanisms and the consequences of a power outage.

[0006] The invention aims to overcome the drawbacks of the prior art

[0007] More specifically, the invention aims to provide an anti-intrusion system that is more secure than that offered by the prior art.

[0008] 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.

[0009] These objectives, as well as others that will appear subsequently, are achieved through the invention, which relates to an anti-intrusion system comprising: - a door, - a lock associated with the door, featuring a mechanical cylinder capable of being operated by an authorized key to move mechanical means of locking the door from a locked position to an unlocked position, or vice versa. - electrically powered reversible cylinder locking mechanisms, - self-contained electrical power supply systems integrated into the door and capable of electrically powering the locking mechanisms, characterized in that the door also incorporates a computer unit configured for: - detect a power supply to the locking devices by autonomous power supply devices, - measure the autonomy of the autonomous power supply systems, - memorize a limit threshold for autonomy corresponding to a predetermined discharge threshold of the autonomous power supply systems. 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.

[0010] Such a system makes it possible to maintain the level of security it provides through the locking means, for the period of time corresponding to the remaining autonomy of the autonomous power supply means up to the limit threshold, a threshold at which the deactivation of the locking means prevents the door from becoming unopenable thereafter.

[0011] This optimizes the system's ability to lock the mechanical cylinder and prevent intrusion during a power failure, for as long as possible before disabling the cylinder locking means.

[0012] According to preferred variants, the door incorporates additional electrical equipment, including the following: - alarm ; - doorbell; - screen ; - short-distance means of communication; - access badge reader.

[0013] The system can then offer various additional functions enriching the user experience, as well as the security it provides.

[0014] For example, a badge can be used to simply disable the locking means in order to allow the door to be opened using a compatible key.

[0015] According to another example, short-range communication means can also be used to disable the means of convicting, in particular using a smartphone on which an application with access rights is installed.

[0016] In this case, advantageously, the computer unit is configured to: - memorize an intermediate threshold of autonomy for autonomous power supply means; - deactivate the power supply to additional electrical equipment when residual energy from the autonomous power supply means reaches or falls below the intermediate autonomy threshold.

[0017] This makes it possible to extend the time of securing the door using active locking means, while allowing the operational maintenance of additional electrical equipment until the intermediate autonomy threshold is reached.

[0018] Preferably, the limit threshold corresponds to a state completely discharged from the autonomous power supply means.

[0019] According to one embodiment, 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,

[0020] and the computer unit is configured to: - detect a power supply via secondary connection means and, - If a power supply is detected via the secondary connection means, deactivate the autonomous power supply means. - if a lack of power supply is detected by the secondary connection means, activate the autonomous power supply means.

[0021] This allows the electrical components of the intrusion detection system to be powered as a priority from a source other than the autonomous power supply means, in order to preserve and / or recharge them.

[0022] Advantageously, the door incorporates long-distance communication means capable of communicating with a computer device remote from the door.

[0023] This allows the consultation of system information from the remote computer device, or the transmission of system information to the remote computer device.

[0024] The remote computing device can correspond to a computer designed to remotely operate the system, or to a smartphone.

[0025] In this case, advantageously, the computer unit is configured to: - memorize a specific autonomy threshold for autonomous power supply means; - deactivate the power supply of long-distance communication means when residual energy from autonomous power supply means reaches or falls below the specific autonomy threshold.

[0026] Such long-distance communication methods can be particularly energy-intensive. Consequently, it is particularly advantageous to deactivate them at a specific battery life threshold, especially soon after a mains power supply is switched off.

[0027] According to a preferred embodiment, the system includes a door closed position sensor connected to the computer unit to transmit a door closed position signal to it, and the computer unit is configured to send a notification to the remote computer device in case of detection of a lack of power supply by the secondary connection means while it receives a closed position signal.

[0028] This allows users or a manager to become aware of a power failure resulting in the use of resources from autonomous power supply means.

[0029] According to a preferred feature, the computer unit is configured, in the event that at least one of the stored thresholds is reached, to: - temporarily reactivate long-distance communication methods; - issue a notification regarding the threshold reached through long-distance communication means; - deactivate long-distance communication devices immediately after the notification is issued.

[0030] In this way, a manager is informed of each autonomy threshold reached by the autonomous power supply means.

[0031] Advantageously, the computer unit is configured to issue the autonomy of the autonomous power supply means with the notification.

[0032] Other features and advantages of the invention will become more apparent upon reading the following description of a preferred embodiment of the invention, given by way of illustrative and non-limiting example, and the accompanying drawings, among which: - [Fig.1] [Fig.1] is a schematic representation of a door of an anti-intrusion system according to the invention; - [Fig.2] [Fig.2] is a schematic representation of the system.

[0033] Fig. 1 illustrates part of the anti-intrusion system according to the invention, and Fig. 2 illustrates the integration of system components on door 1.

[0034] This anti-intrusion system includes a door 1 mounted movable in a frame 11 between a position of closing a passage defined by the frame 11 and a position of releasing the passage.

[0035] The system also includes a lock 2 associated with door 1.

[0036] According to the present embodiment, the lock 2 takes the form of a strip installed on the surface of 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.

[0037] Lock 2 also includes: - mechanical means 22 for locking the door 1 in the closed position; - a mechanical cylinder 21 configured to allow, with the help of a compatible key, the mechanical locking means 22 to be driven from a locked position to an unlocked position, and vice versa.

[0038] The locking means 22 are according to the present embodiment locking bolts 221 intended to protrude from the first part 201 of the lock, and to fit into strikes presented by the second part 202 of the lock 2.

[0039] The lock 2 further includes a handle, allowing the actuation of a beveled bolt to open the door 1 after the unlocking of the locking means 22.

[0040] Of course, the locking means can take a form other than mechanical means, for example magnetic means.

[0041] The anti-intrusion system also includes reversible locking means 3 for the mechanical cylinder 21.

[0042] These locking means 3 are of the electrical type, and are therefore electrically powered.

[0043] The locking means 3 are configured to be able to adopt either an active state in which they block the ability 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.

[0044] The locking means 3 include, for example, a stop and an electric actuator.

[0045] The stop is reversibly movable between an active position in which It prohibits the actuation of cylinder 21, for example the rotation of a cylinder cam, and an inactive position in which the stop releases the rotation of the cam.

[0046] According to a particular embodiment, the stop includes a return spring which continuously forces the stop towards its inactive position.

[0047] The electric actuator is associated with the stop so that, when the electric actuator is supplied with electricity, it causes the stop to move to its active position.

[0048] The locking means 3 further include a control unit that operates the electric actuator, notably by supplying it with electricity or suspending its power supply. The receipt of a release command by the control unit causes the power supply to the electric actuator to be suspended, and thus the stop to move from its active position to its inactive position under the action of its return spring.

[0049] According to the present embodiment, the door 1 incorporates additional electrical equipment.

[0050] These additional electrical components include, in particular, the following: an alarm 61; a doorbell 62; a 63-inch screen; short-distance means of communication 64; at least one access badge reader 65.

[0051] The alarm 61 corresponds to an electronic module designed to trigger an alert upon receiving an intrusion attempt signal from an electronic component of the intrusion detection system, or from another compatible external electronic element. The alarm 61 includes, for example, a loudspeaker capable of emitting an audible alert, or means for controlling a loudspeaker of the intrusion detection system to emit an audible alert.

[0052] The doorbell 62 includes an actuator located on an external face of the door 1, and a loudspeaker capable of emitting a ring, or means for controlling a loudspeaker of the anti-intrusion system to emit a ring.

[0053] The screen 63 is intended to display information about the intrusion detection system and to allow actions to be performed on the system. For example, the screen 63 may be touch-sensitive and allow the entry of an identification code.

[0054] The short-range communication means 64 correspond, according to the present embodiment, to electronic components implementing a telecommunications standard enabling bidirectional data exchange 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.

[0055] According to another embodiment, the short-range communication means 64 can be of the type enabling near-field communication, often referred to by the English acronym NFC.

[0056] It is conceivable that several technologies may be implemented simultaneously by short-range communication means 64, including Bluetooth and NFC.

[0057] The access badge reader 65 is designed to allow the identification of predetermined badges bearing identifiers authorized by the anti-intrusion system.

[0058] The access badge reader 65 can be designed to read magnetic badges, RFID badges, or other types of badges. For example, the access badge reader 65 can be combined with short-range communication means 64 to enable the reading of badges implementing this type of communication protocol.

[0059] According to other conceivable embodiments, the door 1 could not integrate any of these additional electrical equipment, or only one, or even only part of this equipment.

[0060] Gate 1 also incorporates long-distance communication means 66 capable of communicating with a computer device located remotely from gate 1.

[0061] The remote computing device can correspond to a computer workstation or even a smartphone.

[0062] The door 1 further integrates a computer unit 5 coupled to the locking means 3, the additional electrical equipment, and the long-distance communication means 66 in order to operate and control them.

[0063] 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.

[0064] To this end, according to the present embodiment, the intrusion detection system comprises a power supply system including: - a general power supply 42; - 4L autonomous power supply systems

[0065] As mentioned previously, the door 1 is mounted on a frame 11.

[0066] 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.

[0067] 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.

[0068] The primary connection means 421 and the secondary connection means 422 take concrete form of electrical terminals coming into contact with each other when the door 1 is closed.

[0069] The autonomous power supply means 41 are carried by the gate 1.

[0070] These autonomous power supply means 41 are in particular suitable for electrically supplying the locking means 3.

[0071] The self-contained power supply means 41 include at least one electric battery.

[0072] As detailed below, the locking means 41 are configured to be deactivated when a limit threshold SI of the electric battery's autonomy is reached, so as to allow the cylinder 21 to be operated by an authorized key

[0073] The electric battery is preferably rechargeable. When the general power supply 42 is active (door 1 closed), the electric battery is recharged and maintained at its optimal state of charge.

[0074] The autonomous power supply means 41 also include a subsystem for determining the state of charge of the electric battery.

[0075] This determination subsystem makes it possible to establish the residual energy level of the electric battery in order to determine an autonomy.

[0076] An embodiment is conceivable in which the power supply system comprises only self-contained power supply means 4L. In this case, the self-contained power supply means 4L may include a generator associated with a driven element of the door 1 that moves when it is opened, in order to produce electricity each time the door 1 is actuation, and to recharge the battery of the self-contained power supply means 4L.

[0077] The system further 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.

[0078] This closed position sensor 67 is in particular distinct from the secondary connection means 422.

[0079] The computer unit 5 includes processing means, an electronic memory, and is coupled to the electronic and electromechanical components of the intrusion detection system in order to detect events, measure parameters, perform monitoring, and control these components.

[0080] 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 power supply means 41, and more specifically of the electric battery.

[0081] These autonomy thresholds include, among others: - a limit threshold S1; - an intermediate threshold S2 of autonomy, higher than the limit threshold SI; - a specific S3 autonomy threshold, also higher than the SI limit threshold, and preferably higher than the intermediate threshold S2.

[0082] More specifically, 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.

[0083] It should be noted that, according to one conceivable embodiment, the locking means 3 are powered solely by the independent power supply means 41 integrated into the door 1 (i.e., in the absence of any other power supply means such as a general power supply). However, according to another conceivable embodiment, this time including a general power supply, the locking means 3 are powered by the independent power supply means 41 only when the power supply from the general power supply 42 is interrupted.

[0084] In any event, the computer unit 5 is configured to: - measure the autonomy of the autonomous power supply means 41, - memorize the SI limit threshold of autonomy, - deactivate the locking means 3 when the limit threshold SI is reached, so as to allow a drive of the cylinder 21 by an authorized key.

[0085] The limit threshold SI corresponds to a predetermined discharge threshold of the autonomous power supply means 41 integrated into the gate 1.

[0086] According to the preferred embodiment, the limit threshold SI corresponds to a state completely discharged from the autonomous power supply means 41.

[0087] 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 of additional electrical equipment when residual energy from the autonomous power supply means 41 reaches or falls below the intermediate autonomy threshold S2.

[0088] Computer unit 5 is still configured for: - memorize the specific S3 threshold of autonomy of the autonomous power supply means 41; - deactivate the power supply of the long-distance communication means 66 when a residual energy of the autonomous power supply means 41 reaches or falls below the specific autonomy threshold S3.

[0089] The autonomy thresholds, and the deactivations they cause, make it possible to maximize the protection offered by the anti-intrusion system.

[0090] According to the example illustrated in [Fig.2], the thresholds are as follows: - specific threshold S3 = 75% of the maximum capacity of the electric battery of the autonomous power supply means 4; - intermediate threshold S2 = 50% of the maximum capacity of the electric battery of the autonomous power supply means 4; - limit threshold SI = 25% of the maximum capacity of the electric battery of the autonomous power supply means 4.

[0091] Other thresholds and other threshold values ​​are conceivable. In particular, threshold values ​​can be calculated and stored by the computer unit 5 using other system parameters at the time of power loss from the main power supply 42.

[0092] In this example, as long as the autonomous 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.

[0093] The system can in particular notify managers or users of the incident through long-distance communication means 66, which are always active.

[0094] Indeed, the computer unit 5 is configured to send a notification to the remote computer device in the event of detection of a lack of power supply by the secondary connection means while it receives a closed position signal, which corresponds to a case in which the autonomous power supply means 41 are used.

[0095] When the autonomous power supply means 41 reach the specific threshold S3 (electric battery charge at 75%), the computer unit 5 deactivates the long-range communication means 66. This corresponds to a first limited operating state of the intrusion detection system. This first limited operating state provides energy savings but allows the other system functionalities, including the locking means 3, to remain active.

[0096] 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 operating state of the intrusion detection system. This second limited operating state improves energy efficiency but allows the locking means 3 to remain active.

[0097] Finally, when the autonomous power supply means 41 reach the limit threshold SI (electric battery charge at 25%) of autonomy, the locking means 3 are deactivated, subsequently allowing the cylinder 21 to be driven by an authorized key.

[0098] As mentioned previously, other thresholds can be put in place.

[0099] For example, only some of the additional electrical equipment can be deactivated with the intermediate threshold S2, while the means of communication The short-range 64 and access badge reader 65 remain active. Another threshold, preceding the limit threshold SI, triggers the deactivation of these residual additional electrical devices. This allows authentication via access badge or short-range communication means to temporarily disable the locking devices 3 in order to open door 1.

[0100] Computer unit 5 is also configured to: - detect a power supply via secondary connection means 422 and, - if a power supply is detected via the secondary connection means 422, deactivate the autonomous power supply means 41, - in case of detection of a lack of power supply by the secondary connection means 422, activate the autonomous power supply means 41.

[0101] An immediate recharging of the autonomous power supply means 41 is then carried out, preventing them from discharging further.

[0102] The computer unit 5 is advantageously configured to temporarily reactivate the long-distance communication means 66 when a threshold is reached, and to send a notification to the remote computer device via these long-distance communication means 66.

[0103] This notification is intended in particular to warn a user or operator of the system of the crossing of thresholds.

[0104] Furthermore, the computer unit 5 is configured to emit the remaining autonomy of the autonomous power supply means 41 with the notification.

[0105] Following the issuance of the notification, the long-distance communication means 66 are immediately deactivated again in order to save the remaining energy of the electric battery.

[0106] In other words, the computer unit 5 is configured, in the event that at least one of the stored thresholds is reached (the intermediate threshold for example), to: - temporarily reactivate long-distance communication means 66; - issue the notification relating to the threshold reached by means of long-distance communication 66; - deactivate long-distance communication means 66 immediately after the notification is issued.

[0107] 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 Distance between computer unit 5 and a remote computer device, particularly that of a manager, is then possible. Computer unit 4 can, in particular, issue a notification forming a status report including the events that occurred and their timestamps.

[0108] The invention forms an autonomous anti-intrusion system that adapts to the residual energy of the autonomous power supply means 41 to ensure 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 possible intrusion.

[0109] 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 mechanisms are deactivated. However, the system allows this function to be released once all its power has been lost, enabling the operator, after an acceptable security period, to still use their mechanical key.
