Description

[0001] The invention relates to a sensor system for a closure element. The closure element can be designed, in particular, as a door or a window.

[0002] The sensor system comprises a sensor device for detecting operating states of the closure element. The sensor device can determine, as operating states, at least whether the closure element is open or closed and whether a locking element of the closure element is retracted or extended.

[0003] A previously known sensor device is shown in WO 2016 / 149723 A1, referred to there as a device for detecting.

[0004] DE 102011013730 A1 discloses a device for changing a locking state of a window and / or a door, comprising at least one handle olive mounted in at least one olive housing that can be connected to the window and / or door in a rotationally secure manner and is rotatably mounted relative to the olive housing, and at least one electronic evaluation circuit for detecting the position of the handle olive.

[0005] US 2012280783 A1 deals with electronic access control mechanisms that can be locked or unlocked remotely by commands.

[0006] It is an object of the present invention to provide a sensor system for a closure element, in particular a door or a window, which utilizes the determined operating state for a user.

[0007] This object is achieved by the present patent claim 1 or by the present patent claim 2. The dependent claims relate to advantageous embodiments of the invention. According to the invention, the sensor system comprises an electronic device for outputting a message. The message can be generated using the determined operating state.

[0008] According to the invention, a user is thus informed via a message, with the determined operating state being incorporated into the message. The message can thus contain the determined operating state. Additionally or alternatively, the message can vary depending on the determined operating state. The user can receive essential information related to the determined operating state via the message.

[0009] The electronic device can be configured as a computing unit. The sensor device can be connected to the higher-level electronic computing unit by cable or wirelessly. The sensor system can comprise the sensor device and the higher-level computing unit. However, the computing power can also be provided in the sensor device, so that the higher-level computing unit is not necessary, and consequently the sensor device is configured as a sensor system. In this case, the electronic device can be configured as a processor or controller of the sensor device.

[0010] The optional computing unit, in particular a cloud, is located outside the sensor device. The computing unit can be connected to the sensor device via a local network or the internet for communication (also referred to as data transmission or data exchange). In particular, it is intended to locate the computing unit far away from the sensor device.

[0011] The sensor system may comprise a particularly mobile user device, e.g. a mobile phone, a tablet, a laptop, or may be designed to communicate with the mobile user device.

[0012] Furthermore, the sensor system can comprise an electronic detection unit located outside the sensor device, but particularly within its wireless communication range. The detection unit, e.g., configured as a router or gateway, can represent the data transmission connection between the processing unit and the sensor device. The detection unit can represent the data transmission connection between the user device and the sensor device. The detection unit is intended to be located near the sensor device. The detection unit is designed for fixed installation within the communication range of the sensor device.

[0013] The sensor device preferably comprises a transmitting and / or receiving unit. The transmitting and / or receiving unit is designed for communication, i.e., data transmission, in particular wirelessly, with the user device and / or the detection unit and / or the computing unit.

[0014] The transmitting and / or receiving unit is preferably designed for wireless short-range communication, e.g., Bluetooth Low Energy or NFC. The transmitting and / or receiving unit is preferably designed only for wireless short-range communication, in particular Bluetooth Low Energy or NFC. The transmitting and / or receiving unit communicates in particular with the detection unit via wireless short-range communication. The detection unit is preferably located within the communication range of the transmitting and / or receiving unit.

[0015] In particular, the computing unit is located outside the communication range of the transmitting and / or receiving unit.

[0016] It is intended that the transmitting and / or receiving unit arranged in the sensor device communicates with the user device via the detection unit and / or directly. The transmitting and / or receiving unit can communicate directly with the user device wirelessly, provided the user device is within the communication range of the transmitting and / or receiving unit.

[0017] Furthermore, communication from the transmitting and / or receiving unit can also take place via the recording unit and the processing unit with the user device. This is particularly the case if the user device communicates with the processing unit via an external network, in particular the internet or a telecommunications network, and / or the user device is located outside the communication range of the transmitting and / or receiving unit. The recording unit and the processing unit can be connected via the internet and / or a telecommunications network.

[0018] The sensor device comprises at least one sensor. A sensor axis is preferably defined on the sensor.

[0019] The sensor, in turn, preferably comprises at least one coil. For the sake of simplicity, one coil is described in some places below; however, it should always be understood that preferably several coaxial coils are used. The at least one coil preferably detects different impedances and / or different induced voltages.

[0020] Alternatively, the sensor is designed as a light barrier, for example, whereby changes in brightness are detected at the receiver of the light barrier.

[0021] In another alternative, the sensor is designed as a Hall sensor or a reed switch.

[0022] In a further alternative, the sensor can be designed as a switch, in particular as a microswitch, or as a contact foil.

[0023] It is conceivable that the sensor is designed as an acceleration sensor.

[0024] If the sensor comprises a coil, the coil in particular has at least one winding extending around a coil axis; the coil axis corresponds to the sensor axis. The coil is particularly designed to be penetrated by a locking element. The coil is thus designed to be penetrated by a locking element.

[0025] Particularly preferably, the sensor has a through-hole around the sensor axis. The through-hole is designed to be penetrated by the locking element. The locking element preferably moves parallel to the sensor axis. The preferably used coil extends around the through-hole.

[0026] Furthermore, the sensor device preferably comprises an electrical system. The electrical system is designed, in particular, to supply power to and / or control the sensor, in particular the coil(s). Preferably, the electrical system is at least partially electrically connected to the sensor, in particular the coil(s). "Control of the sensor or coil" is understood to mean that the electrical system applies a specific signal to the sensor, in particular the coil, and / or is designed to detect a signal generated in the sensor, in particular a signal induced in the coil.

[0027] The electrical system preferably comprises electronics. The electronics particularly comprise the transmitting and / or receiving unit.

[0028] The electronics preferably comprise an electronic control unit, in particular a processor or controller. If the computing unit is missing, the control unit can, for example, be designed to generate the message. The control unit comprises, in particular, a non-volatile memory. In particular, the electronics are composed of several electronic components. The electronics are designed, in particular, to control the sensor. When using one or more coils, the control of at least one coil, preferably all coils, takes place. In particular, a signal is applied to the coil(s) and / or a signal is picked up at the coil(s).

[0029] The locking element, for example, designed as a door or window, has a door leaf or window leaf. This door leaf or window leaf can be "open" or "closed." Furthermore, the locking element preferably has a locking element. This locking element is, for example, a bolt or a latch of a mortise lock in the door leaf. The locking element has the "bolt extended" or "bolt retracted" state. In the "bolt extended" state, the locking element protrudes further from the locking element leaf than in the "bolt retracted" state. This results in the four basic operating states of the locking element: open-bolt extended state, open-bolt retracted state, closed-bolt extended state, and closed-bolt retracted state.The sensor device can use the sensor to determine whether the locking element is open or closed and whether the locking element is retracted or extended.

[0030] A locking element gap is formed between the door leaf or window leaf, generally referred to as the locking element leaf, and a surrounding locking element frame. In the example of a door, it is particularly provided that a mortise lock is arranged in the door leaf. In the direction of the locking element gap, the mortise lock engages with the face plate. On the opposite side, mounted in the locking element frame or as an integral part of the locking element frame, is the strike plate. A locking element can extend from the face plate. This locking element extends, for example, through the locking element gap along the sensor axis into a corresponding opening in the strike plate. This locking element is, in particular, a bolt or a latch. In windows, there are corresponding elements that can extend through the locking element gap into a corresponding opening in the locking element frame.

[0031] The sensor device presented here is preferably designed to be arranged in this closure element gap. In particular, the sensor device is located on a side of a first closure element part facing the closure element gap, in particular the closure element leaf (in particular the face plate) or the closure element frame (in particular the strike plate). The opposite part without the sensor device is referred to as the "second closure element part." The sensor device is arranged such that the sensor axis is aligned with the locking element and the associated opening. The sensor device is particularly preferably arranged on the closure element leaf side (in particular on the door leaf or window leaf side).

[0032] The sensor system is designed to detect different operating states of the locking element. In particular, the sensor system can determine the following operating states of the locking element: open-bolt-extended state, open-bolt-retracted state, closed-bolt-extended state, and closed-bolt-retracted state. According to the invention, the sensor system uses the determined operating state to send the user a message related to the determined operating state. The message can contain user-friendly information that could be derived from the determined operating state.

[0033] In particular, the sensor device can comprise a detection device for detecting a possible change in the operating state. The fact that a possible change in the operating state has occurred can be detected by the detection device, for example an acceleration sensor or Hall sensor, on the closure element. For example, an acceleration of the closure element indicates a change in the operating state. Likewise, a change in brightness or a change in the magnetic field can be used to detect that a possible change in the operating state has occurred. Thus, the detection device can be designed as a light barrier or a magnetic field sensor. The detection device can serve to wake up the sensor device to determine the operating state. Thus, the detection device can serve to avoid regular determinations of the operating state and / or to increase the intervals for regular determination.

[0034] In order to determine the change in operating state, the sensor device can activate the sensor, in particular energize at least one coil, in response to a signal from the detection device.

[0035] The sensor device can determine the current operating state based on the sensor values. The sensor device can compare the current operating state with a previously determined and electronically stored operating state and thereby determine that the operating state has changed or that the operating state has remained unchanged. Alternatively, the sensor device sends the currently determined operating state to the computing unit. The previous operating state is electronically stored in the computing unit. The computing unit can compare the received current operating state with the previous operating state and thereby determine a change in the operating state or determine that the operating state has remained unchanged.

[0036] A message may be output if the detection device has detected a possible operating state change and the sensor system has subsequently determined that the operating state has changed compared to a previous detection. For example, the acceleration sensor has detected a door movement. The sensor system has subsequently determined that there has been a change in the operating state from a closed-bolt-extended state to an open-bolt-retracted state. This is output as a message.

[0037] It can be provided that a message is output if the detection device has detected a possible change in the operating state and the sensor system has subsequently determined that the operating state has remained unchanged compared to a previous operating state. The sensor system can determine the operating state based on the change detected by the detection device, wherein the sensor system is configured to output a message if the determined operating state remains unchanged in a predetermined time interval before and after the detected change. For example, the acceleration sensor has detected a door movement. For example, someone is shaking the door. The sensor system has subsequently determined that no change in the operating state has occurred compared to the last determination. This relationship can form the basis of a message. The message can be, for example, "The door is being shaken, but the door is not opening."

[0038] The sensor system may be configured to output a message when the detection device detects a possible change in the operating state and both when the operating state changes and when the operating state remains unchanged.

[0039] Alternatively, if the detection device detects a possible change in the operating state and the operating state changes, a message can be output. However, if the operating state remains unchanged, no message is output. Alternatively, if the detection device detects a possible change in the operating state and the operating state remains unchanged, a message can be output. However, no message is output if the operating state changes.

[0040] The output of a message can also depend on another condition. For example, the output of a message can be made dependent on the operating state that existed before the detection device detected a possible change in the operating state. For example, the message will only be output if the closure element was closed before the detection device detected a possible change in the operating state.

[0041] Preferably, the sensor system is designed to output a message upon detecting an operating state in which the locking element is open and the locking element is extended. Thus, a message is output when the open-lock-extended state exists. This state can be particularly critical for fire doors, as this state prevents the fire door from closing. The message may only be output if the open-lock-extended state persists for a time period stored in the electronic device.

[0042] Preferably, the sensor system is designed to output a message upon detecting a change in operating state in which the locking element is opened and the locking element remains extended. Thus, a message is output when the closed-lock-extended state transitions to the open-lock-extended state immediately one after the other. "Immediately" here means, in particular, that no locking-retracted state was detected between the closed-lock-extended state and the open-lock-extended state. Given the above-mentioned sequence of operating states, it can be concluded that the locking element has been entered, for example.

[0043] It is conceivable that a time period is electronically stored in the sensor system for how long the locking element may remain open. This time period can in particular be stored in the electronic device. The sensor system can be designed to issue a message if the time period is exceeded. This could be, for example, a cold storage door. Another example is a lock door. In a lock with at least two doors, one of the doors must always be closed before another door may open. However, it can also be critical to leave a lock door open for too long and thus expose the lock chamber to external influences for too long.

[0044] The sensor system may be configured to output a message when the sensor system receives a command to determine the operating state. Thus, a command from a user, in particular from a mobile user device of the user, can be received wirelessly via the transmitting and / or receiving unit. The sensor device is preferably configured to activate the sensor in response to such a command and to determine at least one operating state of the closure element using the sensor. The operating state determined in this way is output as a message, in particular even when there is no change in the operating state.

[0045] It is conceivable that a time period is stored electronically in the sensor system, wherein the sensor system is designed to detect and accumulate the opening and / or closing of the locking element by means of the sensor. The sensor is thus used to determine, for example, when the operating state changes from a closed-bolt-extended state or a closed-bolt-retracted state to an open-bolt-extended state or an open-bolt-retracted state. For this purpose, for example, the sensor is woken up by the detection device. In another example, the time period begins with a time stored in the electronic device. The electronic device can comprise a timer for determining the time. The sensor system remembers how often the locking element was opened during the time period.Alternatively or additionally, the sensor is used to determine when the operating state changes from an open-bolt extended state or an open-bolt retracted state to a closed-bolt extended state or a closed-bolt retracted state. For example, the sensor is woken up by the detection device for this purpose. The sensor system remembers how often the locking element was closed within the time period. The time period can be one day, for example. The sensor system reacts differently depending on the number of opening and / or closing operations of the locking element within the time period. The sensor system can react at the end of the time period, or the sensor system can already react when a predetermined number of opening and / or closing operations of the locking element have been exceeded within the time period.

[0046] According to the invention, a first alternative provides for a message to be output or omitted depending on the sum of the opening and / or closing operations achieved within the time period. For example, a message can only be output at the end of the time period if the sum of the opening and / or closing operations exceeds a predetermined limit value. Alternatively, a message can only be output at the end of the time period if the sum of the opening and / or closing operations falls below a predetermined limit value. A message can be output within the time interval if a predetermined limit value has already been exceeded at this time. The limit values ​​for exceeding or falling below at the end of the time period or for exceeding within the time period can differ from one another.

[0047] For example, a room should only be cleaned at the end of a workday if it has been entered at least once. If the door to the room is opened at least once during the workday, the cleaning staff receives the message "Please clean room" at the end of the workday. If the locking element is not opened during the workday, the message is omitted. It is also conceivable that the message is only issued if the locking element has not been opened during the workday. In this case, the message could read: "Room does not need to be cleaned." If the locking element is opened during the workday, the message is omitted. According to a second alternative, the invention provides that the sensor system is designed to vary the type of message issued based on the total number of opening and / or closing operations achieved within the time period.The message can be displayed, in particular, at the end of the time period. For example, a message may always be displayed at the end of the time period, with the content varying depending on the number of opening and / or closing operations. In the example above, the cleaning staff receives a message at the end of the workday. If the locking element has been opened, the message reads "Please clean room," otherwise "Room does not need to be cleaned."

[0048] It is conceivable that a time period is additionally stored in the sensor system, wherein the sensor system is designed to detect and add up the retraction and / or extension of the locking element by means of the sensor. The time period can correspond to the time period for adding up the opening and / or closing processes. The sensor system can be designed to output a message or to omit a message depending on the sum of the retraction and / or extension processes reached within the time period. Alternatively, the sensor system can be designed to vary the type of message depending on the sum of the retraction and / or extension processes reached within the time period.

[0049] The sensor system may be configured to wirelessly transmit the message to the mobile user device. This is referred to as message delivery. The message may be displayed on the mobile user device as a text message, a ringtone, or a combination of text message and ringtone.

[0050] The sensor system may be configured to send the message to a user's fixed computing device. This is referred to as the message output. This is referred to as the message output. For example, it may be a monitoring PC. The message may be displayed on the computing device as a text message, a ringtone, a light signal, or a combination thereof.

[0051] It is conceivable that the sensor system is designed to trigger a visual or acoustic warning device. This is referred to as the output of a message. For example, a warning light or siren can be activated when a door is unlocked and / or opened.

[0052] It is conceivable that the sensor system is configured to modify a digital calendar. This is referred to as outputting a message. For example, the sensor can detect that a door to a room has not been opened within a certain period of time. From this, the sensor system can conclude that the room is not being used. The sensor system can output a message to the digital calendar indicating that the room is not being used. The digital calendar can then adjust the room occupancy schedule based on this message.

[0053] It may be that the sensor system only outputs the message if location information about the user who is to receive the message corresponds to a specification stored in the sensor system. This is particularly useful if the output of the message is designed as sending the message to the mobile user device. Preferably, the sensor system only outputs the message if location information about a mobile user device to which the message is sent corresponds to a specification. This is particularly location information, e.g. based on satellite navigation data and / or GSM location of the user device. For example, it is defined as a specification that the user device must exceed a defined distance from the closure element and / or the sensor device. Thus, a message is only output if the user device exceeds the distance.A user who is close to the closure element and can determine the operating status by visual contact is thus relieved of an unnecessary message.

[0054] For example, it is additionally or alternatively defined as a requirement that the user device must remain within a defined distance from the closure element and / or the sensor device. Thus, a message is only issued if the additional information is present that the user device is within the specified distance. A user who is too far away from the closure element to be able to respond to the message is thus relieved of an unnecessary message.

[0055] Alternatively, it can be provided that the sensor system always outputs the message. It can be provided that the sensor system outputs the message regardless of a specification, e.g. a spatial distance to a user. Thus, a message is preferably always output, regardless of the position of a mobile user device to which the message is to be sent. For example, a message is always output if the detection device has detected a possible change in the operating state. For example, a message is always output if the detection device has detected a possible change in the operating state and it is determined by means of the sensor that the operating state has changed. For example, a message is always output if the detection device has detected a possible change in the operating state and it is determined by means of the sensor that the operating state has remained unchanged.In another example, a message is always issued when the open-bolt-extended operating state exists for at least a predetermined period of time. In another example, a message is always issued when the closed-bolt-extended state changes directly one after the other to the open-bolt-extended state. It is conceivable that a message is always issued when a time period in which the locking element may remain open is exceeded. It can be provided that the message is always issued upon a user command. It is conceivable that a message is always issued at the end of a time period that is based on the sum of the opening processes, the closing processes, the bolt retraction processes and / or the bolt extension processes.

[0056] In particular, the sensor device has, preferably at the highest or thickest point, a height of at most 2.5 mm, preferably at most 2.3 mm, particularly preferably at most 2.1 mm.

[0057] Preferably, it is provided that the one sensor can be used to determine whether the closure element is open or closed and whether a locking element of the closure element is retracted or extended. Thus, a single sensor is sufficient to detect the at least four operating states.

[0058] The following describes the functionality of the sensor device using the example of a door and a sensor with at least one coil. However, the same functionality applies when applied to a window or other closure element. WO 2016 / 149723 A1 describes a sensor and its use. The sensor used according to the present invention can be configured identically or similarly. Accordingly, the control of the coil(s) from WO 2016 / 149723 A1 can also be used for the present invention.

[0059] As already described in WO 2016 / 149723 A1, it was found that electrical measured values ​​at the at least one coil change both due to the state of the locking element (referred to as the locking element in WO 2016 / 149723 A1) and, to a lesser extent, due to the state of the door. The electrical measurement using the sensor alone can therefore be used to determine the state of the locking element and also the state of the door, without the need for additional switches or changes to the locking element. Since the coil axis is arranged such that the at least one coil can be penetrated by the locking element, it is possible to use the coil to detect whether the locking element extends through the coil or not. For this purpose, the locking element is of course at least partially made of metal. The impedance changes when the door is closed compared to when the door is open due to the proximity of the partially metal second closure element part.If the sensor device is arranged on the door leaf, in particular on the faceplate, the sensor can detect whether the at least partially metal door frame, in particular the metal strike plate, is located near the coil and thus whether the door is closed or not. If the sensor device is arranged on the door frame, in particular on the strike plate, the coil can detect whether the at least partially metal door leaf, in particular the metal faceplate or the metal lock, is located near the coil and thus whether the door is closed or not.

[0060] If the coil(s) are to be kept as low as possible, it is advisable to design the electronics (measuring device in WO 2016 / 149723 A1) in such a way that they are suitable for measuring the coil's impedance while it is being subjected to an alternating voltage signal or an alternating current signal. The sensor can be equipped with only one coil, resulting in the smallest possible thickness of the sensor device. The coil's impedance changes when the locking element is retracted or extended, and to a small extent when the partially metal second locking element part (when the door is closed) comes into the coil's area. The coil's impedance can be compared with specified values.

[0061] The reliability of determining the status of the locking element and the door leaf can be significantly increased by applying signals of different frequencies to the coil one after the other using the electrical system. The impedance is then determined at these different frequencies and compared with predetermined values. For example, if measurements are taken at three frequencies and the status of the locking element and, if applicable, the door is determined from each measurement, a majority decision can be made if the results differ. On the other hand, it is often possible that two states at a certain frequency produce very similar measured values ​​and can therefore hardly be distinguished, so that for this reason alone, a measurement at different frequencies is advisable.

[0062] When measurements are taken at multiple frequencies, power consumption increases compared to a single measurement. It may therefore be advisable to equip the sensor with at least two coils. The two coils are coaxial with each other. These coils consist of a transmitting coil and a receiving coil. The transmitting coil is supplied with alternating current. The induced voltage is recorded in the receiving coil. The induced voltage in the receiving coil changes more significantly than the impedance, especially when the door state changes. This avoids measurements at different frequencies, thus minimizing power consumption.

[0063] The sensor can comprise at least one transmitting coil and at least two receiving coils. Reliability can be further increased if an additional receiving coil is provided, so that a receiving coil is arranged on either side of at least one transmitting coil. The electronics detect the difference in the voltage induced in the two receiving coils while the at least one transmitting coil is supplied with alternating current.

[0064] Consequently, it is preferably provided that the sensor comprises at least three coils or four coils. In the preferred embodiment of the sensor with at least three coils, the at least three coils are arranged one above the other. The coils can be arranged coaxially to one another. The transmitting coil(s) is / are located, in particular symmetrically, between the two receiving coils. If an iron core (the locking element) is located exactly symmetrically in this arrangement, exactly the same voltage is induced in the two receiving coils; the differential voltage between the two receiving coils is therefore 0. However, if the iron core shifts in one direction or the other, the arrangement becomes asymmetrical and an induced differential voltage results across the two receiving coils.Likewise, the induced differential voltage changes when the door is closed compared to an open door due to the proximity of the second, at least partially metallic, closure element part. It is possible to arrange a transmitting coil between the receiving coils. Furthermore, it is also possible to arrange at least two transmitting coils between the two receiving coils. In this case, the two transmitting coils are, in particular, part of a common circuit. The transmitting coils can emit a common signal. Likewise, the two receiving coils can be part of a common circuit. Therefore, one can also speak of a transmitting coil with two winding regions and a receiving coil with two winding regions.

[0065] The sensor can, regardless of the number of coils, detect the door states (open and closed), as well as the locking element states (bolt retracted and extended). Thus, the sensor device can detect the operating states (open / bolt extended), (open / bolt retracted), (closed / bolt extended), and (closed / bolt retracted) using the sensor. The electronics at least energize the coil and / or directly detect the impedance or induced voltage. Further evaluations, such as comparison with stored values, can also be performed in the electronics, particularly in the control unit, or in the higher-level processing unit.

[0066] Preferably, the sensor system, in particular the sensor device, can detect the operating state "sensor outside the operating position." In the operating state "sensor outside the operating position," the sensor is located outside the operating position, wherein the sensor device is attached to the first closure element part in the operating position. In particular, the operating state "sensor outside the operating position" is determined by sensor values ​​that characterize a distance to the first, at least partially metallic closure element part, wherein the distance is greater than in the operating position.

[0067] The sensor device comprises fastening means for attachment to the first closure element part. The fastening means can in particular be designed as the adhesive element. If the sensor comprises at least one transmitting coil between two receiving coils, a different, in particular lower, voltage is induced in the receiving coil facing the fastening means when the distance from the first closure element part is greater than in the operating position. In particular, the differential voltage between the two receiving coils also changes. This allows the operating state "sensor outside the operating position" to be determined.

[0068] Thus, the sensor system, in particular the sensor device, can detect a further operating state, namely the operating state "sensor outside the operating position", in addition to the operating states open-bolt extended, open-bolt retracted, closed-bolt extended and closed-bolt retracted.

[0069] Preferably, a message is always output when the operating state "Sensor outside the operating position" is detected.

[0070] Instead of the sensor configured as coils in the door gap, other sensors are conceivable. In particular, the sensor device may comprise a sensor, in particular a first sensor, to detect whether the door leaf or window leaf is open or closed. The sensor system may comprise a sensor, in particular a second sensor, to detect whether the locking element is retracted or extended.

[0071] The sensor, which is designed to detect whether the door leaf or the window leaf is open or closed, can be designed, for example, as a Hall sensor or a reed switch. In this case, a magnet is arranged on the second closure element part and the Hall sensor or the reed switch is arranged on the first closure element part. Alternatively, the sensor, which is designed to detect whether the door leaf or the window leaf is open or closed, can be designed as a light barrier. For example, the light barrier can be designed as a reflective light barrier. The second closure element part can reflect the light from the light barrier in the closed state, while in the open state there is no reflection of the light from the second closure element part. Alternatively, the sensor, which is designed to detect whether the door leaf or the window leaf is open or closed, can be designed as a switch, in particular a microswitch.For example, an actuating element protrudes into the door gap to operate the switch. The actuating element can also serve another purpose, such as serving as the latch of a mortise lock.

[0072] The sensor, which is designed to detect whether the locking element is retracted or extended, can be designed, for example, as a Hall sensor or a reed switch. In this case, a magnet, which interacts with the Hall sensor or reed switch, is arranged on the locking element, for example. Alternatively, the sensor, which is designed to detect whether the locking element is retracted or extended, can be designed as a light barrier. For example, the light barrier can be designed as a reflective light barrier or a transmitted light barrier. The light can be reflected by the lock in one of the locking element states, e.g. in the extended state, but not in the other locking element state, e.g. in the retracted state. Alternatively, the sensor, which is designed to detect whether the locking element is retracted or extended, can be designed as a switch, in particular as a microswitch. In one of the locking element states, e.g.In one locking element state, e.g., in the extended state, the switch can be actuated, while in the other locking element state, e.g., in the retracted state, the switch is not actuated. Alternatively, a contact foil can be used. An electrical signal is generated on the contact foil by touching the locking element. In one locking element state, e.g., in the extended state, a signal is generated on the contact foil by the locking element, while in the other locking element state, e.g., in the retracted state, the locking element does not generate a signal on the contact foil. Alternatively, the sensor designed to detect whether the locking element is extended or retracted can be designed as an acceleration sensor. In this case, the acceleration sensor is connected to the locking element. The initial state of the locking element must first be set.After that, with each movement of the locking element, the acceleration sensor and the history can be used to determine whether the locking element is moving into the retracted or extended state.

[0073] The first sensor and / or the second sensor may be arranged on the door or window frame. Alternatively, the first sensor and / or the second sensor may be arranged on or in the door leaf. For example, the first sensor and / or the second sensor may be arranged in a mortise lock. Preferably, both the first sensor and the second sensor are arranged together on a locking element part, i.e., the locking element frame or the locking element leaf. The transmitting and / or receiving unit may, particularly in these cases, communicate with the computing unit via a cable. For example, the transmitting and / or receiving unit may be designed as a bus interface.

[0074] The object of the invention is also achieved by an arrangement with a closure element and a sensor system according to the invention.

[0075] The invention will now be described in more detail using an exemplary embodiment. In the following: Figure 1 shows an arrangement according to the invention with a sensor device according to the invention according to all variants, Figures 2 - 9 show the sensor device according to the invention according to a first variant, Figure 10 shows the sensor device according to the invention according to a second variant, and Figures 11 - 14 show the sensor device according to the invention according to a third variant, Figure 15 shows the sensor device according to the invention according to a fourth variant,

[0076] Figure 1 shows a purely schematic representation of an arrangement 2. The arrangement 2 comprises a sensor device 1 and a closure element 3, here designed as a door. Only a section of the closure element 3 is shown.

[0077] The locking element 3 comprises a lock 4 in a door leaf; generally referred to as the first locking element part 65. The lock 4, in turn, has a faceplate 7. Located in the lock 4 is a locking element 5, here designed as a bolt. The locking element 5 can be extended and retracted, for example, using a key. The locking element 5 is displaceable along a coil axis 22. This coil axis 22 is part of the sensor device 1 and will be explained in more detail below.

[0078] The lock 4 can have an additional locking element 6, for example in the form of a latch. In the illustrated embodiment, the locking element 5 penetrates the sensor device 1. However, the sensor device 1 can also be designed and arranged such that the additional locking element 6 (latch) penetrates the sensor device 1 and is detected by the sensor device 1.

[0079] Opposite the door leaf is the frame, generally referred to as the second locking element part 66, of the assembly 2. Located within this frame, as a separate component or integral portion, is the strike plate 8. The strike plate 8 has a latch opening 9 and a bolt opening 10. The bolt element 5 extends into this bolt opening 10 in the extended state. Accordingly, the further bolt element 6 extends into the latch opening 9.

[0080] When the locking element is closed, a locking element gap 11 is formed between the face plate 7 and the strike plate 8. The sensor device 1 is located in this locking element gap 11. In this position, the sensor device 1 is in the operating position.

[0081] The sensor device 1 has a front side 12 and a rear side 13. The front side 12 and rear side 13 are defined, in particular, perpendicular to the coil axis 22. The rear side 13 forms the mounting surface of the sensor device 1 and is attached, in particular glued, to a support surface on the faceplate 7. The sensor device 1 and thus also the support surface can extend beyond the faceplate 7.

[0082] The front side 12 faces the closure element gap 11.

[0083] Figure 1 further shows a sensor system 60 comprising the sensor device 1. In addition, the sensor system 60 also includes a higher-level processing unit 61, a detection unit 62 and a user device 64, for example a mobile phone. For clarification, Figure 1also purely schematically, the transmitting and / or receiving unit 63 in the sensor device 1. The transmitting and / or receiving unit 63 communicates, in particular wirelessly, directly with the computing unit 61 and / or via the detection unit 62 with the computing unit 61. The detection unit 62 is located in particular in the communication range for wireless data transmission with the sensor device 1, for example, near the door. The detection unit 62 is preferably connected to the computing unit 61 by cable for data transmission. However, wireless transmission is also possible here.

[0084] The user device 64 can communicate, in particular wirelessly, directly with the transmitting and / or receiving unit 63 or via the computing unit 61 or the detection unit 62 with the sensor device 1.

[0085] In a variant not shown, it is also possible to arrange the sensor device 1 on the other side, namely on the striking plate 8.

[0086] The Figures 2 to 9 show in different representations the basic structure of the sensor device 1 as well as certain special features of the first variant of the sensor device 1.

[0087] In the following, unless explicitly stated otherwise, reference is always made to the Figures 2 to 9 Reference is made.

[0088] The sensor device 1 comprises a sensor 20. The sensor 20, in turn, has at least one coil 21, which is shown here only purely schematically. The coil 21 defines the coil axis 22. In particular, it is provided that the at least one coil 21 is formed in or on a sensor board part 24. In particular, the coil 21 is a conductor track in the sensor board part 24. The sensor board part 24 lies on a base element 23. In the first three exemplary embodiments, the base element 23 is formed in particular from an electrically non-conductive material, in particular plastic. Both the base element 23 and the coil 21 and the sensor board part 24 have a through-hole 25. The coil axis 22 extends through this through-hole 25.

[0089] The sensor device 1 is arranged in the arrangement 2 in particular such that the locking element 5 can extend through this through-hole 25 along the coil axis 22. Preferably, at least one or two transmitting coil(s) and two receiving coils, each comprising at least one winding, preferably several windings, are arranged one behind the other in the direction of the coil axis 22. The transmitting coil(s) is / are enclosed by the receiving coils. Thus, starting from the rear side 13 of the sensor device 1, first a receiving coil is arranged, then the transmitting coil(s), and then another receiving coil. The structure with three coils 21 is shown in Fig. 8 shown.

[0090] In Figure 2, which shows a top view of the front side 12, the receiver coil 21 shown covers the transmitter coils located behind it as well as the further receiver coil facing the rear side. The voltage difference induced in the two receiver coils makes it possible to detect the proximity of metal to the second closure element part 66. This makes it possible to detect whether the closure element is open or closed. Furthermore, a change in the induced voltage in the receiver coils can be used to detect whether the locking element 5 is extended or retracted. Thus, the operating states of the locking element 3, namely an open-lock extended state, an open-lock retracted state, a closed-lock extended state, and a closed-lock retracted state, can be detected by means of the sensor 20.Since the metal content of the closure element parts 65, 66 and the locking element 5 can vary, the aforementioned operating states are assigned to sensor values, in particular amplitude changes and / or phase shifts of the voltages or voltage differences induced in the receiver coils, during commissioning of the sensor device 1. Thus, the sensor device is calibrated during commissioning.

[0091] The sensor device 1 can detect a further operating state, namely the "sensor out of operating position" operating state. This is a state in which the sensor 20 or the entire sensor device 1 has been removed from the first closure element part 65. In particular, the induced voltage induced in the receiver coil facing the first closure element part 65 changes.

[0092] The sensor device 1 has a height in the direction of the coil axis 22 of at most 2.5 mm, preferably at most 2.3 mm, particularly preferably at most 2.1 mm.

[0093] Because the sensor device 1 is mounted on the locking element blade 65, the sensor device 1 requires a separate power supply in the form of energy storage devices 45. For improved retrofitability, a wired connection to an external power supply is not provided. The sensor device determines the operating state of the locking element. The open-bolt extended state, the open-bolt retracted state, the closed-bolt extended state, the closed-bolt retracted state, and the sensor out-of-operating-position state can be determined.

[0094] The sensor device 1 determines the different operating states. The sensor device 1 sends information about the determined operating state to the computing unit 61. According to the invention, the computing unit 61 is designed to output a message generated using the received information about the operating state. For this purpose, the computing unit 61 sends the message to the user device 64. The computing unit 61 sends the message to the mobile user device 64, for example, via a telecommunications network or the Internet. The message is displayed on the display of the user device 64. In addition, an acoustic signal from the user device 64 can indicate receipt of the message.

[0095] The sensor device 1 comprises an acceleration sensor 53 as a detection device. If the acceleration sensor 53 detects a movement of the closure element 3, the sensor device 1 concludes a possible change in the operating state. The sensor device 1 then energizes the sensor 20 and determines the operating state. The determined operating state is then only output as a message if the operating state has changed compared to a previously determined operating state. This is determined by the computing unit 61. Alternatively, a message is only output if, or also if, the operating state has remained unchanged compared to a previously determined operating state. The computing unit 61 can perform the comparison. For this purpose, the computing unit 61 can have at least a previous operating state stored.

[0096] When a message is output by the sensor system 60 can be configured within the sensor system 60. The following paragraphs present several ways in which the output of a message can be configured. Several configuration options can be provided in the sensor system 60: The sensor system 60 will always output a message when an open-bolt-extended state exists.

[0097] The sensor system 60 always sends a message when the operating state changes from the closed-bolt-extended state to the open-bolt-extended state in immediate succession.

[0098] The sensor system 60 always sends a message when a time period in which the operating state open-bolt-retracted is determined is exceeded.

[0099] The sensor system 60 will always output a message when the sensor system 1 has received a command to determine the operating state from the mobile user device 64.

[0100] The sensor system 60 will always issue a message when the sensor device 1 is out of the operating position.

[0101] The sensor system 60 will always output a message at the end of a stored time period, which is based on the sum of the opening processes within the stored time period.

[0102] The sensor system 60 will always output a message at the end of a specified time period based on the total number of openings within the specified time period if the total number of openings within the time period exceeds a threshold. For example, if at least five openings occur within a day, a message will be output at the end of the day.

[0103] In one example of the invention, additional information is available to the computing unit 61. If the additional information corresponds to a specification, a message is output. The specification can be configurable in the sensor system 60. The check as to whether the additional information corresponds to the specification is carried out by the computing unit 61. If the check shows that the specifications are met, the computing unit 61 creates the message. For example, the additional information can be location information of the user device 64. The location information is determined, for example, via GSM positioning. For example, the computing unit 61 determines as additional information that the user device 64 is located outside the spatial area that can be closed by the closure element 3.If it is stored in the computing unit 61 that a message is to be output when the user device 64 is outside the spatial area, the computing unit 61 will output the message.

[0104] In the embodiment of the Figures 2 to 9 Both the base element 23 and the coil 21 and the sensor board part 24 have a through-hole 25. The coil axis 22 extends through this through-hole 25.

[0105] The sensor device 1 is arranged in the arrangement 2 in particular such that the locking element 5 can extend through this through-cutout 25 along the coil axis 22.

[0106] In addition to the sensor 20, the sensor device 1 comprises an electrical system 40. This electrical system 40 is closed with a cover 30. Figures 2 and 3 show this lid 30. In Figure 4 the cover 30 is hidden.

[0107] The sensor device 1 comprises a holding element 31, in particular made of plastic. In particular, the holding element 31 and the base element 23 form a single-piece component. Figure 5 shows the holding element 31 in isolation. In Figure 6 the cover 30 and the holding element 31 are hidden.

[0108] As in particular the Figures 4 and 6 show, the electrical system 40 comprises an electronics system 41 and two energy storage devices 45. The energy storage devices 45 are designed here as button batteries.

[0109] The electronics 41 consists of several electronic components 43 arranged on an electronic circuit board 42. The electronic components 43 are located in a potting compound 44.

[0110] The electronic board part 42 is designed as one piece with a memory board part 46. For the sake of clarity, Figure 6a dashed, imaginary boundary is drawn between electronic board part 42 and memory board part 46.

[0111] On the memory board part 46 there are energy storage contacts 47 for the two energy storage devices 45. For example Figure 4 As shown, two energy storage receptacles 32 are formed in the holding element 31. The two energy storage receptacles 32 are through-holes in the holding element 31. The two energy storage devices 45 can be inserted into these energy storage receptacles 32 and can be contacted by the energy storage contacts 47.

[0112] Furthermore, the holding element forms an electronics recess 33, also designed as a through-hole, surrounded by side walls 39. The electronics 41, in particular the potting compound 44 with the electronic components 43, protrudes into this electronics recess 33.

[0113] The electrically conductive connection between the electronics board part 42 and the sensor board part 24 is made here via a plug connection 27. This plug connection 27 also extends into the electronics recess 33 of the holding element 31.

[0114] For example Figure 2 shows, the entire electrical system 40 is arranged on one side of the sensor 20. Figure 2 shows a spatial direction 26 that is defined perpendicular to the coil axis 22 and intersects the coil axis 22. The electronics 41 and the energy storage devices 45 are arranged along this spatial direction 26. The electronics 41 is located between the energy storage devices 45 and the sensor 20.

[0115] Figure 7shows in detail the area between sensor 20 and electrical system 40. The cover 30 is hidden. It is clearly visible that the retaining element 31 has a retaining element rim 36 on the front side 12. This retaining element rim 36 surrounds the electrical system 40, in particular the electronics recess 33 and the energy storage receptacles 32. The cover 30, in particular in an elastic design, for example made of silicone, can be plugged onto the retaining element rim 36. When plugged in, the edges of the cover 30 engage around the retaining element rim 36.

[0116] The cover 30 and the sensor board part 34 thus form the outer side and thus also the housing of the sensor device 1 on the front side 12.

[0117] The rear side 13, thus the mounting surface and the rear housing of the sensor device 1, is formed by the base element 23 and the outer side of the electronics board part 42 and memory board part 46.

[0118] Figure 8 shows the same representation as Figure 7 , but without retaining element 31. The two Figures 7 and 8 illustrate the offset between electronic board part 42 and coil(s) 21. In Figure 8 Three coils 21 are shown as an example. In the variant shown, all coils (21) are not only offset, but even have a distance 49 from the electronic circuit board part 42.

[0119] Figure 8 further shows a coil region 28 in which the three coils 21 are located. This coil region 28 is, in particular, a component of the sensor board part 24. The coil region 28 extends from the upper end of the uppermost coil 21 to the lowermost end of the lowermost coil 21. The coil region 28 has a first height 29 parallel to the coil axis 22. The electronics board part 42 extends parallel to the coil axis 22 over a second height 48. This second height 48 is preferably smaller than the first height 29.

[0120] Figure 9 clarifies the Figure 2 marked section A:A. This illustration clearly shows the exact structure of the base element 23. The base element 23 accordingly comprises the base plate 34 for receiving the sensor board part 24. Two side rails 35 of the base element 23 are arranged laterally of the sensor board part 24 for the positive reception of the sensor board part 34.

[0121] Figure 10 shows a variant of the sensor device 1. The basic structure of the sensor device 1 is as in the Figures 2 to 9 described. Only the cover 30 and its connection to the holding element 31 is designed differently here. The cover according to Figure 10is pushed onto the holding element 31 perpendicular to the coil axis 22 and counter to the spatial direction 26. The cover 30 has a locking tongue 37. A tongue receptacle 38 is formed in the holding element 31. In the closed state, the locking tongue 37 engages in the tongue receptacle 38.

[0122] The Figures 11 to 14 show a variant of the sensor device 1 in which the front side 12 is formed by these elements, not the rear side 13. Accordingly, the two circuit board parts 42, 46 also function as a cover and thus form part of the housing.

[0123] Figures 11 and 12 show the closed sensor device 1. The sensor board part 24 is designed here as in the previous variants, but is not shown for the sake of clarity.

[0124] Figure 13 shows an exploded view. Figure 14shows only the inside of the electronic board part 42 and memory board part 46, also here in a one-piece design.

[0125] In the variant according to the Figures 11 to 14 The outer side of the holding element 31 forms the housing on the rear side 13 of the sensor device. Here, too, the holding element 31 is formed integrally with the base element 32.

[0126] At the front side 12, the retaining element 31 is closed by the electronics board part 42 and the memory board part 46. The outer side of these board parts 42, 46 thus forms the housing of the sensor device on the front side 12.

[0127] The two energy storage devices 45 are inserted into the holding element 31. As is particularly Figure 14As shown, corresponding energy storage contacts 47 are located on the memory board part 46. These energy storage contacts 47 can contact the energy storage devices 45 directly or indirectly in the assembled state of the sensor device 1. For indirect contacting, energy storage contacts 47 are also located in the holding element 31, which establish the electrically conductive contact between the memory board part 46 and the energy storage device 45.

[0128] How Figure 14 also shows, the electronics 41 with electronic components 43 and potting compound 44 is located on the inside of the electronic circuit board part 42.

[0129] Figure 15 shows a fourth embodiment of a sensor device 1 according to the invention in an exploded view. In the following, the similarities and differences to the first embodiment of the Figures 2-9 explained.

[0130] The sensor device 1 comprises an adhesive element 50, which, as in the first embodiment, forms the rear side 13 of the sensor device 1. A circuit board is integrally and materially connected to the adhesive element 50. The circuit board is glued to the adhesive element 50.

[0131] The circuit board comprises the memory board part 46 and the electronics board part 42. The memory board part 46 and the electronics board part 42 are thus formed in one piece and from the same material. Furthermore, a base plate 23 is formed in one piece and from the same material with the electronics board part 42 and the memory board part 46. The sensor board part 24 is arranged on the base plate 23. The sensor board part 24 is integrally connected to the base plate 23, in particular soldered. The sensor board part 24 contains the coils 21, with at least one or two transmitting coils 21 being arranged between two receiving coils 21 within the sensor board part 24. The receiving and transmitting coils 21 are formed with the same or parallel coil axes 22.

[0132] The coils 21 are electrically and firmly connected to the base plate 23, in particular by soldering. The coils 21 are connected to the electrical system 40, i.e., the electronics 41 and the energy storage devices 45, via the base plate 23.

[0133] At the same time, the base plate 23 separates the coils 21 from the rear side 13 of the sensor device 1. The base plate is formed as part of the circuit board.

[0134] A light barrier 52 is arranged within the sensor board part 24. The position of the locking element 5 can be detected by the light barrier 52 in addition to the sensor 20 embodied as coils 21. However, it is also conceivable to design the fourth embodiment without the light barrier 52 and to detect the operating states solely by the sensor 20.

[0135] The holding element 31 is attached to the adhesive element 50.

[0136] The holding element 31 is designed as a plastic frame. The holding element 31 forms the electronics recess 33 as a through-opening, which serves as a tray for the potting compound 44. Furthermore, the electronics recess 33 also frames the sensor 20.

[0137] The holding element 31 forms the energy storage receptacle 32 as a through-opening. The energy storage devices 45 are arranged within the energy storage receptacle 32. First electrical contacts for a first pole of the energy storage devices 45 are formed on the storage circuit board part 46. Electrical conductor elements lead to the electronics in or on the storage circuit board part 46. Energy storage contacts 47 are located on the second pole of the energy storage devices 45.

[0138] Unlike the embodiment of the Figures 2-9, the energy storage contacts 47 are designed as elastic tongues of a cover 30. The cover 30 is electrically conductive, in particular metallic. The cover 30 comprises contact tongues 54, so that the electrical current can flow from the second pole of the energy storage devices 45 via the energy storage contacts 47 to the contact tongues 54. The contact tongues 54 rest resiliently and electrically against a contact pad 55 of the memory board part 46. Electrical conduction elements in or on the memory board part 46 lead from the contact pad to the electronics.

[0139] The adhesive element 50, the circuit board 42, 46 and the holding element 31 together form a rear housing part.

[0140] The fact that the energy storage contacts 47 and the contact tongues 54 are spring-loaded and rest against the energy storage element 45 and the contact pad 55 under mechanical tension ensures the flow of current. Furthermore, the energy storage contacts 47 press the energy storage elements 45 against the electrical contacts for the first pole, thus ensuring the flow of current here as well.

[0141] For electrical insulation of the cover 30, the cover 30 is integrally bonded, in particular glued, to a non-conductive foil 51. The foil 51 forms part of the front side 12 of the sensor device 1. The foil 51 and the cover 30 together form a front housing part.

[0142] Furthermore, the front side 12 is formed by the potting compound 44 and the sensor board part 24. Alternatively, and not shown, it is possible to cover the potting compound 44 and possibly the sensor board part 24 with the film 51. This materially connects the transmitting and / or receiving unit 63 and the sensor 20 to the front side 12 and the rear side 13. In the area of ​​the electronics 41 and the sensor 20, the sensor device 1 is designed without a housing, i.e., the front and rear sides 12, 13 are materially connected to one another.

[0143] The cover 30 is reversibly detachably secured to the holding element 31, particularly by a positive fit. For this purpose, the cover 30 comprises connecting elements 56, which can be guided through recesses 59 in the holding element 31. Then, by sliding the cover 30, the connecting elements 56 are brought into positive engagement with projections 58 of the holding element 31 and thus secured. The connecting elements 56 and the projections 58 are designed such that the energy storage contacts 47 and the contact tongues 54 are mechanically tensioned when the cover is closed.

[0144] In the examples of the Figures 2 to 9 and 10 the cover 30 may have projections that press the energy storage devices 45 against the memory board part.
