Description

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

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

A previously known sensor device shows WO 2016/149723 A1 , there referred to as a device for detection.

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

This problem is solved by the present patent claim 1. 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 with the aid of the determined operating state.

According to the invention, a user is thus informed by means of a message, the operating state ascertained being included in the message. The message can thus contain the determined operating status. Additionally or alternatively, the message can vary depending on the determined operating state. By means of the message, the user can receive essential information that is related to the ascertained operating state.

The electronic device can be designed as a computing unit. The sensor device can be wired or wirelessly connected to the higher-level electronic processing unit. The sensor system can include the sensor device and the superordinate computing unit. However, the computing power can also be provided in the sensor device, so that the superordinate computing unit is not necessary and consequently the sensor device is designed as a sensor system. In this case, the electronic device can be designed as a processor or controller of the sensor device.

The optional computing unit, in particular a cloud, is arranged outside the sensor device. The computing unit can communicate with the sensor device via a local network or the Internet (also as data transmission or data exchange designated). In particular, it is provided to arrange the computing unit far away from the sensor device.

The sensor system can be a particularly mobile user device, e.g. B. comprise a mobile phone, a tablet, a laptop or be designed for communication with the mobile user device.

Furthermore, the sensor system can have an electronic detection unit which is arranged outside the sensor device, but in particular in its wireless communication area. The detection unit, for example designed as a router or gateway, can represent the data-transmitting connection between the computing unit and the sensor device. The detection unit can represent the data-transmitting connection between the user device and the sensor device. The detection unit is provided to be arranged in the vicinity of the sensor device. The detection unit is designed for stationary installation in the communication area of the sensor device.

The sensor device preferably comprises a transmitting and / or receiving unit. The transmitting and / or receiving unit is designed for communication, that is to say data transmission, in particular wirelessly, with the user device and / or the detection unit and / or the computing unit.

The transmitting and / or receiving unit is preferred for wireless close-range communication, e.g. B. Bluetooth Low Energy or NFC. The transmitting and / or receiving unit is preferably designed only for wireless close-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 area of the transmitting and / or receiving unit.

The computing unit is located in particular outside the communication area of the transmitting and / or receiving unit.

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

In addition, the transmission and / or reception unit can also communicate with the user device via the acquisition unit and the computing unit. This is particularly the case when 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 outside the communication range of the transmitting and / or receiving unit. The acquisition unit and the computing unit can be connected via the Internet and / or a telecommunications network.

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

The sensor in turn preferably comprises at least one coil. For the sake of simplicity, a / the coil is described in places below; However, it should always be understood that a plurality of coaxial coils are preferably used. Different impedances and / or different induced voltages are preferably detected with the at least one coil.

Alternatively, the sensor is designed, for example, as a light barrier, with changes in brightness in particular being detected at the receiver of the light barrier.

In a further alternative, the sensor is designed as a Hall sensor or as a reed switch.

In a further alternative, the sensor is designed as a switch, in particular as a microswitch, or as a contact film.

It is conceivable that the sensor is designed as an acceleration sensor.

If the sensor comprises a coil, the coil has in particular at least one winding which extends around a coil axis; where the coil axis corresponds to the sensor axis. The coil is used in particular to be penetrated by a locking element. The coil is therefore designed to be penetrated by a locking element.

The sensor particularly preferably has a through cutout all around the sensor axis. The through recess is designed to be penetrated by the locking element. The locking element preferably moves parallel to the sensor axis. The coil that is preferably used extends around the through cutout.

Furthermore, the sensor device preferably comprises an electrical system. The electrical system is in particular for the power supply and / or control of the sensor, in particular the Coil (s). The electrical system is preferably at least partially electrically conductively connected to the sensor, in particular the coil (s). “Control of the sensor or the coil” is to be understood as meaning that the electrical system applies a certain signal to the sensor, in particular the coil, and / or is designed to supply a signal generated in the sensor, in particular a signal induced in the coil capture.

The electrical system preferably includes electronics. The electronics include, in particular, the transmitting and / or receiving unit.

The electronics preferably include an electronic control unit, in particular a processor or controller. If the computing unit is missing, z. B. the control unit can be designed to generate the message. The control unit includes, 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 coil or several coils, the at least one coil, preferably all coils, is controlled. In particular, a signal is applied to the coil (s) and / or a signal is picked up at the coil (s).

The closure 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 closure 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 state "bolt extended" or "bolt retracted". In the "bolt-extended" state, the locking element protrudes further from the closure element blade than in the "bolt-retracted" state. This results in the four basic operating states of the locking element: open-bolt-extended-condition, opened-bolt-retracted-condition, closed-bolt-extended-condition and closed-bolt-retracted-condition. The sensor device can determine by means of the sensor whether the closure element is open or closed and whether the locking element is retracted or extended.

A closure element gap is formed between the door leaf or the window leaf, generally referred to as the closure element leaf, and a surrounding closure element frame. Using the door as an example, provision is made in particular for a mortise lock to be arranged in the door leaf. In the direction of the closure element gap, the mortise lock closes with the faceplate. The strike plate is located on the opposite side, mounted in the locking element frame or as an integral part of the locking element frame. From the faceplate out can a locking element extend. This locking element extends z. B. through the closure element gap along the sensor axis into a corresponding opening in the strike plate. This locking element is in particular a bolt or a trap. In the case of the window, there are corresponding elements which can extend through the closure element gap into a corresponding opening in the closure element frame.

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 blade (in particular the faceplate) or the closure element frame (in particular the strike plate). The opposite part without a sensor device is referred to as the "second closure element part". The sensor device is arranged in such a way 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 side or on the window leaf side).

The sensor system is designed to detect different operating states of the closure element. In particular, the sensor system can determine the operating states of the locking element: open-bolt-extended state, opened-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 that is related to the determined operating state. In this case, the message can contain user-friendly information that could be derived from the determined operating state.

In particular, the sensor device can comprise a detection device for recognizing a possible change in the operating state. The detection device, for example an acceleration sensor or Hall sensor, on the closure element can detect that a possible change in the operating state occurs. For example, an acceleration of the closure element indicates a change in the operating state. Likewise, by means of a change in brightness or a change in the magnetic field, it can be recognized that there is possibly a change in the operating state. The detection device can thus be designed as a light barrier or as a magnetic field sensor. The detection device can serve to wake up the sensor device to determine the operating state. The detection device can thus serve to avoid regular determinations of the operating state and / or to increase the intervals for regular determinations.

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

The sensor device can determine the current operating state on the basis of the sensor values. The sensor device can compare the current operating state with a previously determined and electronically stored operating state and thereby establish that the operating state has changed, or establish that the operating state has remained unchanged. Alternatively, the sensor device sends the current, determined operating state to the computing unit. The previous operating status is electronically stored in the arithmetic unit. The processing unit can compare the received current operating state with the previous operating state and thereby determine a change in the operating state or establish that the operating state has remained unchanged.

It may be that a message is output when the detection device has detected a possible change in the operating state and the sensor system has then determined that the operating state has changed compared to a previous determination. For example, the acceleration sensor has detected a door movement. The sensor system has then determined that there is a change in the operating state from the closed-bolt-extended state to an opened-bolt-retracted state. This is output as a message.

It can be provided that a message is output when the detection device has detected a possible change in the operating state and the sensor system has then determined that the operating state has remained unchanged compared to a previous operating state. The sensor system can determine the operating state in response to the change detected by the detection device, the sensor system being designed 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 then determined that there was no change in the operating state compared to the last determination. This connection can be the basis of a message. The message can e.g. B. read: "The door is being rattled, the door will not open."

It may be that the sensor system is designed 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. Alternatively, if the detection device detects a possible change in the operating state and the operating state changes, a message can be output. On the other hand, a message is not output if the operating status remains unchanged. Alternatively, if the detection device detects a possible change in the operating state and the operating state remains unchanged, a message can be output. In contrast, a message is not output if the operating status changes.

The output of a message can also depend on a further condition. For example, the output of a message can be made dependent on which operating state existed before the detection device detected a possible change in operating state. For example, the message is only output if the closure element was closed before the detection device detected a possible change in the operating state.

The sensor system is preferably designed to output a message when an operating state is determined in which the locking element is open and the locking element is extended. A message is thus output when the open-bolt-extended state is present. This condition can be particularly critical in the case of fire protection doors, since the condition prevents the fire protection door from closing. The message may only be output if the open-bolt-extended state persists for a time stored in the electronic device.

It is preferably provided that the sensor system is designed to output a message when a change in the operating state is determined in which the closure element is opened and the locking element remains extended. A message is thus output if the closed-bolt-extended state changes to the opened-bolt-extended state in immediate succession. “Immediately” here means in particular that no bolt-retracted state was detected between the closed-bolt-extended state and the opened-bolt-extended state. Given the order of the operating states mentioned, it can be concluded that the closure element z. B. has occurred.

It is conceivable that a period of time is electronically stored in the sensor system for how long the closure element may remain open. The period of time can in particular be stored in the electronic device. The sensor system can be designed to output a message when the time period is exceeded. This can be, for. B. be a cold store door. Another example is a door of a lock. In a lock with at least two doors, one of the doors must always be closed before another door can open. However, it can also be critical to open a door of a lock for too long and thus to expose the lock area to external influences for too long.

It may be that the sensor system is designed 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 designed to activate the sensor in response to such a command and to determine at least one operating state of the closure element by means of the sensor. The operating state determined in this way is also output as a message in particular when there is no change in the operating state.

It is conceivable that a period of time is electronically stored in the sensor system, the sensor system being designed to detect and total the opening and / or closing of the closure element by means of the sensor. Using the sensor is thus z. B. determined 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 example, the sensor is woken up by the detection device for this purpose. In another example, the time period begins with a time stored in the electronic device. The electronic device can include a timer for determining the time. The sensor system remembers how often the closure element was opened in the period of time. Alternatively or additionally, the sensor is used to determine when the operating state changes from an open-bolt-extended state or an opened-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 closure element was closed in the period of time. The period of time can e.g. B. be one day. Depending on the number of opening processes and / or closing processes of the closure element within the time span, the sensor system can react differently. The sensor system can react at the end of the time period or the sensor system can already react if a predetermined number of opening processes and / or closing processes of the closure element has been exceeded within the time period.

Provision can be made for a message to be issued or for a message to be omitted depending on the sum of the opening processes and / or closing processes that are achieved within the time span. For example, at the end of the time span, a message can only be output if the sum of the opening processes and / or closing processes exceeds a predetermined limit value. Alternatively, at the end of the time span, a message can only be output if the sum of the opening processes and / or closing processes falls below a predetermined limit value. It can be inside of the time interval, a message can be output if a predetermined limit value has already been exceeded at this point in time. The limit values for exceeding or falling below at the end of the time span or exceeding them already within the time span can differ from one another.

For example, a room should only be cleaned at the end of a working day if the room has been entered at least once. If the door to the room is opened at least once during the working day, the cleaning staff receives the message at the end of the working day: "Please clean the room". If the closure element is not opened within the working day, the message is omitted. It is also conceivable that the message is only output if the closure element has not been opened within the working day. In this case the message could be: "Room does not need to be cleaned". If the closure element is opened within the working day, the message is omitted.

Alternatively, it can be provided that the sensor system is designed to vary the type of message output from the sum of the opening processes and / or closing processes that is achieved within the period of time. In particular, the message can be output at the end of the time period. In particular, it can be the case that a message was always output at the end of the time period, the content varying with the sum of the opening processes and / or closing processes. In the example above, the cleaner receives a message at the end of the working day. If the closure element has been opened, the message is "Please clean the room", otherwise "Room does not need to be cleaned".

It is conceivable that, as an alternative or in addition, a period of time is stored in the sensor system, the sensor system being designed to detect and add up the retraction and / or extension of the locking element by means of the sensor. The time span can correspond to the time span for adding up the opening and / or closing processes. The sensor system can be designed to output a message or to omit a message as a function of the sum of the retraction processes and / or extension processes that are achieved within the time span. Alternatively, the sensor system can be designed to vary the type of message as a function of the sum of the retraction processes and / or extension processes that is achieved within the time span.

It may be that the sensor system is designed to wirelessly send the message to the mobile user device. This is referred to as the output of the message. The message can be displayed on the mobile user device as a text message, as a ringtone, or as a combination of text message and ringtone.

It may be that the sensor system is designed to send the message to a fixed computing device of the user. This is referred to as the output of the message. This is known as the task of the message. For example, it can be a monitoring PC. The message can be displayed on the computing device as a text message, as a ringtone, or as a light signal, or a combination thereof.

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

It is conceivable that the sensor system is designed to modify a digital calendar. This is referred to as the output of a message. For example, it can be determined by means of the sensor that a door to a room has not been opened within a period of time. The sensor system can conclude from this that the room is not being used. The sensor system can send a message to the digital calendar that the room is not in use. The digital calendar can then adjust the room occupancy plan based on this message.

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 takes the form of sending the message to the mobile user device. The sensor system preferably only outputs the message if location information about a mobile user device to which the message is sent corresponds to a specification. In particular, this involves location information, e.g. based on satellite navigation data and / or GSM positioning 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 from the sensor device. Thus, a message is only issued when the user device exceeds the distance. A user who is in the vicinity of the closure element and can determine the operating state through eye contact is thus relieved of an unnecessary message.

For example, it is additionally or alternatively defined as a specification that the user device must fall below a defined distance from the closure element and / or from the sensor device. A message is thus only output if the additional information is available that the user device is below the distance. A user who is too far away from the closure element to be able to react to the message is thus relieved of an unnecessary message.

Alternatively, it can be provided that the sensor system always outputs the message. It can be provided that the sensor system receives the message independently of a specification, e.g. B. a spatial distance to a user outputs. A message is thus 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 when the detection device has recognized a possible change in the operating state. For example, a message is always output when the detection device has recognized 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 when the detection device has recognized 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 output if the operating state open-bolt-extended is present for at least a predefined period of time. In another example, a message is always output if the closed-bolt-extended state changes to the open-bolt-extended state in immediate succession. It is conceivable that a message is always output when a period of time in which the closure element is allowed to remain open is exceeded. It can be provided that the message is always output in response to a command from the user. It is conceivable that a message is always output at the end of a period of time which is based on the sum of the opening processes, the closing processes, the bolt retracting processes and / or the bolt extending processes.

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

It is preferably 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. A single sensor is therefore sufficient to detect the at least four operating states.

The mode of operation of the sensor device is described below using the example of a door and a sensor with at least one coil. However, the same functionality results when used on 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 designed identically or similarly. In particular, the control of the coil (s) can be switched off accordingly WO 2016/149723 A1 can also be used for the present invention.

As in WO 2016/149723 A1 described, it was found that electrical measured values on the at least one coil vary both as a result of the state of the locking element (in WO 2016/149723 A1 referred to as locking element) as well as to a small extent by changing the door state. The state of the locking element and also the state of the door can thus be deduced from the electrical measurement by means of the sensor alone, without additional buttons or changes to the locking element being necessary. Since the coil axis is arranged in such a way 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 is now extending 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 in comparison with an open door due to the proximity of the partly metal second closure element part. When 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 in the vicinity of the coil and thus the door is closed or not. When the sensor device is arranged on the door frame, in particular on the strike plate, the coil can be used to detect whether the at least partially metal door leaf, in particular the metal faceplate or metal lock, is near the coil and thus the door is closed or not .

If the lowest possible overall height is to be achieved by the coil (s), it is advisable to use the electronics (measuring device in WO 2016/149723 A1 ) in such a way that it is suitable for measuring the impedance of the coil while an alternating voltage signal or an alternating current signal is applied to it. The sensor can be equipped with only one coil, which results in the smallest possible thickness of the sensor device. The impedance of the coil changes when the locking element is retracted or extended and to a lesser extent when the partially metal second locking element part (by closing the door) comes into the area of the coil. The impedance of the coil can be compared with given values.

The reliability of the determination of the state of the locking element and the door leaf can be significantly increased by applying signals of different frequencies to the coil in succession by means of the electrical system. The impedance is then determined at these different frequencies and compared with predetermined values. If z. B. is measured at three frequencies and conclusions are drawn from each measurement about the state of the locking element and possibly the state of the door, a majority decision can be made in the event of different results. On the other hand, it is often also possible that two states deliver very similar measured values at a certain frequency and thus can hardly be differentiated, so that for this reason alone a measurement at different frequencies is indicated.

When measuring at multiple frequencies, the power consumption is consequently increased compared to a single measurement. It can be useful to equip the sensor with at least two coils. The at least two coils are coaxial with one another. It is a transmitting coil and a receiving coil. Alternating current is applied to the transmitter coil. The induced voltage is recorded in the receiving coil. The induced voltage in the receiving coil changes more clearly than the impedance, especially when the door status changes. In this way measurements at different frequencies can be avoided, whereby the power consumption can be minimized.

The sensor can comprise at least one transmission coil and at least two reception coils. The reliability can be increased even further if a further receiving coil is provided, so that a receiving coil is arranged on each side of at least one transmitting coil. By means of the electronics, the difference between the voltage induced in the two receiving coils is detected while the at least one transmitting coil is supplied with alternating current.

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 there is an induced differential voltage at the two receiving coils. Likewise, the induced differential voltage changes when the door is closed in relation to an open door due to the proximity of the second at least partially metal closure element part. It is possible to arrange a transmitter coil between the receiver coils. Furthermore, it is also possible to arrange at least two transmission coils between the two reception coils. The two transmitter coils are in particular part of a common circuit. The transmitter coils can emit a common signal. The two receiving coils can also be part of a common circuit. It is therefore also possible to speak of a transmitting coil with two winding areas and a receiving coil with two winding areas.

Regardless of the number of coils, the sensor can detect the door states open and closed as well as the locking element states bolt-retracted and bolt-extended. The sensor device can thus use the sensor to detect the operating states open-bolt-extended, opened-bolt-retracted, closed-bolt-extended and closed-bolt-retracted. In this case, the electronics at least energize the coil and / or detect the impedance or induced voltage, which can be transmitted. The further evaluations, for example the comparison with stored values, can also take place in the electronics, in particular in the control unit, or in the superordinate computing unit.

The sensor system, in particular the sensor device, can preferably detect the operating state “sensor outside the operating position”. In the “sensor outside the operating position” operating state, the sensor is outside the operating position, the sensor device being attached to the first closure element part in the operating position. In particular, the “sensor outside the operating position” operating state is determined by sensor values which characterize a distance from the first, at least partially metal, closure element part, the distance being greater than in the operating position.

The sensor device comprises fastening means for fastening 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 transmission coil between two reception coils, a different, in particular lower, voltage is induced in the reception coil facing the fastening means at a distance from the first closure element part that is greater than in the operating position than in the operating position. In particular, this also changes the differential voltage between the two receiving coils. This allows the "sensor outside the operating position" operating state to be determined.

Thus, the sensor system, in particular the sensor device, can use the sensor in addition to the operating states open-bolt-extended, opened-bolt-retracted, closed-bolt-extended and closed-bolt-retracted to another operating state, namely the operating state "sensor outside the operating position "detect.

It is preferably provided that a message is always output when the operating state “sensor outside the operating position” is detected.

Instead of the sensor designed as a coil in the door gap, other sensors are conceivable. In particular, it can be that the sensor device comprises a, in particular a first, sensor in order to detect whether the door leaf or the window leaf is open or closed. The sensor system can comprise one, in particular a second, sensor in order to detect whether the locking element is retracted or extended.

The sensor, which is designed to detect whether the door leaf or the window leaf is open or closed, can, for. B. be designed as a Hall sensor or as a reed switch. Here, a magnet is arranged on the second closing element part and the Hall sensor or the reed switch is arranged on the first closing 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 reflection light barrier. In the closed state, the second closure element part can reflect the light from the light barrier, while in the open state there is no reflection of the light on 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 with which the switch can be actuated protrudes into the door gap. The actuator can also serve another purpose and z. B. serve as a case of a mortise lock.

The sensor, which is designed to detect whether the locking element is retracted or extended, can, for. B. be designed as a Hall sensor or as a reed switch. Here is z. B. arranged on the locking element, a magnet which interacts with the Hall sensor or reed switch. 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 reflection light barrier or a transmission light barrier. The light can be in one of the locking element states, e.g. B. in the extended state, are reflected on the bolt, in the other bolt element state, z. B. in the retracted state, however, not. 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. B. in the extended state, the switch can be operated, while in the other locking element state, z. B. in the retracted state, the switch is not actuated. Alternatively, a contact foil can be used. When the locking element is touched, an electrical signal is generated on the contact foil. In a locking element state, e.g. B. in the extended state, a signal is generated on the contact foil by the locking element, while in the other locking element state, z. B. in the retracted state, the locking element does not generate a signal on the contact foil. Alternatively, the sensor, which is designed to detect whether the locking element is retracted or extended, can be designed as an acceleration sensor. The acceleration sensor is connected to the locking element. In this case, it must first be set in which state the locking element is initially. Afterwards, with every movement of the locking element, the acceleration sensor and the history indicate whether the bolt is moving into the retracted or extended state.

It may be that the first sensor and / or the second sensor are arranged on the door or window frame. Alternatively, the first sensor and / or the second sensor can be arranged on or in the door leaf. For example, the first sensor and / or the second sensor can be arranged in a mortise lock. Both the first sensor and the second sensor are preferably arranged together on a closure element part, that is to say the closure element frame or the closure element sheet. The transmitting and / or receiving unit can, in particular in these cases, communicate with the computing unit in a wired manner. For example, the transmitting and / or receiving unit can be designed as a bus interface.

Figure 1 shows an arrangement 2 in a purely schematic representation. 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.

The locking element 3 comprises a lock 4 in a door leaf; generally referred to as first closure element part 65. The lock 4 in turn has a faceplate 7. By doing Lock 4 is a locking element 5, here designed as a bolt. The locking element 5 can be retracted and extended with a key, for example. 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 detail.

The lock 4 can have a further locking element 6, for example in the form of a latch. In the exemplary embodiment shown, the locking element 5 penetrates the sensor device 1. However, the sensor device 1 can also be designed and arranged such that the further locking element 6 (trap) penetrates the sensor device 1 and is detected by the sensor device 1.

The frame, generally referred to as the second closure element part 66, lies opposite the door leaf of the arrangement 2. The strike plate 8 is located in this frame as a separate component or integral area. The strike plate 8 has a latch opening 9 and a bolt opening 10. The locking element 5 extends into this locking opening 10 in the extended state. The further locking element 6 accordingly extends into the latch opening 9.

In the closed state of the closure element, a closure element gap 11 is formed between the faceplate 7 and the strike plate 8. The sensor device 1 is located in this closure element gap 11. Here, the sensor device 1 is in the operating position.

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 fastened, 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.

The front side 12 faces the closure element gap 11.

Figure 1 furthermore shows a sensor system 60 comprising the sensor device 1. In addition, the sensor system 60 also comprises a superordinate computing unit 61, a detection unit 62 and a user device 64, for example a mobile phone. For clarity shows Figure 1 also 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 sensing unit 62 with the computing unit 61. The sensing unit 62 is located in particular in the communication area for wireless data transmission with the sensor device 1, for example in the vicinity of the door. The detection unit 62 is preferably wired connected to the computing unit 61 for data transmission. However, wireless transmission is also possible here.

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

In a variant not shown, it is also possible to arrange the sensor device 1 accordingly on the other side, namely on the strike plate 8.

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.

In the following, unless explicitly stated otherwise, the Figures 2 to 9 Referenced.

The sensor device 1 comprises a sensor 20. The sensor 20 in turn has at least one coil 21, which is only shown here 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 rests on a base element 23. In the first three exemplary embodiments, the base element 23 is formed in particular from 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 cutout 25. The coil axis 22 extends through this through recess 25.

The sensor device 1 is arranged in the arrangement 2 in particular in such a way that the locking element 5 can extend through this passage recess 25 along the coil axis 22. At least one or two transmitter coils and two receiver coils, each of which comprises at least one winding, preferably several windings, are preferably arranged one behind the other in the direction of the coil axis 22. The transmitter coil (s) is / are enclosed by the receiver coils. Thus, starting from the rear side 13 of the sensor device 1, first a receiver coil, then the transmitter coil (s) and then a further receiver coil are arranged. The structure with three coils 21 is shown in FIG Fig. 8 shown.

In Figure 2 , which represents a top view of the front side 12, the illustrated receiver coil 21 covers the transmission coils located behind it and the further receiver coil facing the rear side. By the induced in the two receiver coils Voltage difference, it is possible to detect the proximity of metal of the second closure element part 66. This makes it possible to detect whether the closure element is open or closed. Furthermore, by changing the induced voltage in the receiver coils, it can be detected whether the locking element 5 is extended or retracted. The operating states of the locking element 3, namely an open-bolt-extended state, an opened-bolt-retracted state, a closed-bolt-extended state and a closed-bolt-retracted state, can thus be detected by means of the sensor 20 become. Since the metal portion of the locking element parts 65, 66 and the locking element 5 can vary, the mentioned 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, when the sensor device 1 is put into operation. The sensor device is thus calibrated during commissioning.

The sensor device 1 can detect a further operating state, namely the operating state “sensor outside the operating position”. 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 that is induced in the receiver coil facing the first closure element part 65 changes here.

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.

Because the sensor device 1 is fastened to the closure element sheet 65, the sensor device 1 requires an independent energy supply in the form of energy storage devices 45. A wired connection to an external energy supply is not provided for better retrofitting. The sensor device determines the operating state of the closure element. Here, the open-bolt-extended state, the opened-bolt-retracted state, the closed-bolt-extended state, the closed-bolt-retracted state and the sensor-out-of-operation-position state can be determined.

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. The computing unit 61 is designed according to the invention to output a message that is generated by means of the received information about the operating state. For this purpose, the processing unit 61 sends the message to the user device 64. The processing 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 by the user device 64 can indicate the receipt of the message.

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 that there is 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 arithmetic unit 61. Alternatively, a message is only output if the operating state has remained unchanged compared to a previously determined operating state. The computing unit 61 can carry out the comparison. For this purpose, the computing unit 61 can have stored at least the previous operating state.

When a message is output by the sensor system 60 can be configurable in the sensor system 60. In the following paragraphs, several ways in which the output of a message can be configured are presented. Several configuration options can be provided in the sensor system 60:
The sensor system 60 will always output a message when there is an open-bolt-extended condition.

The sensor system 60 is always a message if the operating state changes from the closed-bolt-extended state to the opened-bolt-extended state in immediate succession.

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

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.

The sensor system 60 will always output a message when the sensor device 1 is outside of the operating position.

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.

The sensor system 60 is always output a message at the end of a stored period of time, which is based on the sum of the opening processes within the stored time period, if the sum of the opening processes within the period of time exceeds a limit value. So z. B. If there are at least five opening processes within a day, a message is issued at the end of the day.

In one example of the invention, the arithmetic unit 61 has additional information. If the additional information corresponds to a specification, a message is output. The specification can be configurable in the sensor system 60. The computing unit 61 checks whether the additional information corresponds to the specification. If the check shows that the specifications have been met, the processing unit 61 creates the message. For example, the additional information can be location information of the user device 64. The location information is z. B. determined via GSM positioning. For example, the computing unit 61 establishes 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 arithmetic unit 61 that a message is to be output when the user device 64 is located outside the spatial area, the arithmetic unit 61 will output the message.

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

The sensor device 1 is arranged in the arrangement 2 in particular in such a way that the locking element 5 can extend through this passage recess 25 along the coil axis 22.

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

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 one-piece component. Figure 5 shows the holding element 31 in isolation. In Figure 6 the cover 30 and the holding element 31 are hidden.

Like in particular the Figures 4 and 6th show, the electrical system 40 comprises electronics 41 and two energy stores 45. The energy stores 45 are designed here as button batteries. The electronics 41 are composed of a plurality of electronic components 43 which are arranged on an electronic circuit board part 42. The electronic components 43 are located in a potting compound 44.

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

On the memory board part 46 there are energy storage contacts 47 for the two energy stores 45. Such as, for example Figure 4 shows, two energy storage receptacles 32 are formed in the holding element 31. The two energy storage receptacles 32 are through cutouts in the holding element 31. The two energy storage receptacles 45 can be inserted into these energy storage receptacles 32 and can be contacted by the energy storage contacts 47.

Furthermore, the holding element forms an electronics cutout 33, also designed as a through cutout, surrounded by side walls 39. The electronics 41, in particular the potting compound 44 with the electronic components 43, protrude into this electronics cutout 33.

The electrically conductive connection between electronic circuit board part 42 and sensor circuit board part 24 takes place here via a plug connection 27. This plug connection 27 also extends into the electronics recess 33 of the holding element 31.

Like 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, which is defined perpendicular to the coil axis 22 and intersects the coil axis 22. The electronics 41 and the energy stores 45 are arranged along this spatial direction 26. The electronics 41 are located between the energy stores 45 and the sensor 20.

Figure 7 shows in detail the area between sensor 20 and electrical system 40. The cover 30 is hidden. It can be clearly seen here that the holding element 31 has a holding element rim 36 on the front side 12. This holding 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 configuration, for example made of silicone, can be slipped onto the holding element rim 36. In the attached state, the edges of the cover 30 encompass the retaining element rim 36.

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

The rear 13, thus the mounting surface and the rear housing of the sensor device 1, is formed by the base element 23 and the outside of the electronic board part 42 and memory board part 46.

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

Figure 8 also shows a coil area 28 in which the three coils 21 are located. This coil area 28 is in particular part of the sensor board part 24. The coil area 28 extends from the upper end of the uppermost coil 21 to the lowermost end of the lowermost coil 21. The coil area 28 has a first height 29 parallel to the coil axis 22. The electronic 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.

Figure 9 illustrates the in Figure 2 marked section A: A. The exact structure of the base element 23 can be clearly seen in this illustration. The base element 23 accordingly comprises the base plate 34 for receiving the sensor circuit board part 24. Two side rails 35 of the base element 23 for the form-fitting receiving of the sensor circuit board part 34 are arranged on the side of the sensor circuit board part 24.

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

The Figures 11 to 14 show a variant of the sensor device 1 in which the rear side 13 is not formed by the outer sides of the electronic board part 42 and memory board part 46, but the front side 12 is formed by these elements. Accordingly, the two circuit board parts 42, 46 also function here as a cover and in this respect form part of the housing.

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

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

In the variant according to the Figures 11 to 14 the outside 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 in one piece with the base element 32.

On the front side 12, the holding element 31 is closed by the electronic board part 42 and the memory board part 46. The outer side of these circuit board parts 42, 46 thus forms the housing of the sensor device on the front side 12.

The two energy stores 45 are inserted into the holding element 31 here. How in particular Figure 14 shows, there are corresponding energy storage contacts 47 on the memory board part 46. These energy storage contacts 47 can contact the energy storage 45 directly or indirectly in the assembled state of the sensor device 1. For indirect contacting, there are also energy storage contacts 47 in the holding element 31, which establish the electrically conductive contact between the memory board part 46 and the energy storage 45.

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

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

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

The circuit board comprises the memory board part 46 and the electronic board part 42. The memory board part 46 and the electronic board part 42 are thus formed in one piece and of the same material. Furthermore, a base plate 23 is formed in one piece and of the same material with the electronic 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 materially connected to the base plate 23, in particular soldered on. The sensor board part 24 contains the coils 21, at least one or two Transmitting coil (s) 21 are arranged between two receiving coils 21 within the sensor board part 24. Here, the receiving and transmitting coils 21 are designed with the same or parallel coil axes 22.

The coils 21 are electrically and cohesively connected to the base plate 23, in particular soldered on. The coils 21 are connected to the electrical system 40, d. h of the electronics 41 and the energy storage 45 connected.

At the same time, the base plate 23 spaced the coils 21 from the rear side 13 of the sensor device 1. The base plate is designed as part of the circuit board.

A light barrier 52 is arranged within the sensor board part 24. By means of the light barrier 52, the position of the locking element 5 can be detected in addition to the sensor 20 designed as coils 21. It is also conceivable, however, to configure the fourth exemplary embodiment without a light barrier 52 and to detect the operating states only by means of the sensor 20.

The holding element 31 is fastened on the adhesive element 50.

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 trough for the potting compound 44. In addition, the electronics recess 33 also frames the sensor 20.

The holding element 31 forms the energy storage receptacle 32 as a through opening. The energy stores 45 are arranged within the energy store receptacle 32. First electrical contacts for a first pole of the energy stores 45 are formed on the memory board part 46. Electrical line elements lead in or on the memory board part 46 to the electronics. Energy storage contacts 47 are applied to the second pole of energy storage 45.

Unlike in the embodiment of 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 device 45 via the energy storage contacts 47 to the contact tongues 54. The contact tongues 54 are resiliently and electrically contacting against a contact field 55 of the memory board part 46. Electrical conduction elements lead from the contact field in or on the memory board part 46 to the electronics.

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

The fact that the energy storage contacts 47 and the contact tongues 54 are designed to be resilient and rest under mechanical tension on the energy storage 45 or on the contact field 55 ensures the flow of current. In addition, the energy storage contacts 47 press the energy storage 45 against the electrical contacts for the first pole, so that the flow of current is also ensured here.

For the electrical insulation of the cover 30, the cover 30 is materially connected to a non-conductive film 51, in particular with adhesive tape. The film 51 forms part of the front side 12 of the sensor device 1. The film 51 and the cover 30 together form a front-side housing part.

Furthermore, the front side 12 is formed by the potting compound 44 and the sensor board part 24. As an alternative and not shown, it is possible to cover the potting compound 44 and possibly the sensor circuit board part 24 with the film 51. As a result, the transmitting and / or receiving unit 63 and the sensor 20 are materially connected 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, ie. H. Front and rear sides 12, 13 are materially connected to one another.

The cover 30 is attached to the holding element 31 in a reversibly releasable manner, in particular in a form-fitting manner. For this purpose, the cover 30 comprises connecting elements 56, which can be guided through recesses 59 in the holding element 31. Thereafter, by moving the cover 30, the connecting elements 56 are brought into a form fit with projections 58 of the holding element 31 and thus fastened. The connecting elements 56 and the projections 58 are designed in such a way that the energy storage contacts 47 and the contact tongues 54 are mechanically tensioned when the cover is closed.

In the embodiments of Figures 2 to 9 and 10 the cover 30 can have projections which press the energy storage device 45 against the memory board part.
