Description

Title: Switching device

The invention relates to a switching device for supplying at least one consumer with electrical energy according to the preamble of claim 1. The switching device comprises at least one output. The output is used to change from a first electrical state of the consumer to a second electrical state of the electrical consumer.

In hotel or dormitory rooms according to the prior art, there is often a switching device for supplying a consumer with electrical energy on a wall. A hotel guest or resident has an access authorization card. Using the access authorization card, access to the hotel or dormitory room could previously be obtained at an access control device. The access authorization card is then inserted into the switching device, as a result of which a switch is actuated and the electrical consumers in the hotel or dormitory room are supplied with electrical energy. If the user leaves the hotel or living room room, the user must remove the access authorization card from the switching device again in order to be able to gain access to the hotel or dormitory room again afterwards. This means that consumers are always switched off when leaving the hotel or dormitory room. The access authorization card has recently been replaced by an access attribute on a mobile phone. As a result, it is no longer possible to continue using the switching device.

It is the object of the present invention to provide a switching device which enables energy to be saved even without an access authorization card when operating a hotel, a dormitory or a similar facility.

The above object is achieved by a switching device with the features of claim 1. Further features and details of the invention emerge from the subclaims, the description and the drawings.

According to the invention it is provided that the switching device comprises a communication device for wireless communication with a mobile device.

In other words, the switching device is designed such that it communicates wirelessly with a mobile device. According to the invention, communication with a mobile device is therefore provided instead of a contact with an access authorization card so that the electrical loads in a spatial area can move from a first state to a second state, in particular can be switched on and / or can remain in the second state, in particular can stay switched on. The operating state of the output is changed again, in particular, so that the consumer returns to the first state when communication with the mobile device fails, ie has ended.

The switching device can have a control device. The switching device can comprise an electronic processor or controller as a control device. The switching device can comprise an electronic memory as part of the control device.

The communication device can be designed as a transmitting and receiving unit. The transmitting and receiving unit is particularly useful for short-range communication, e.g. B. Bluetooth Low Energy trained. The transmitting and receiving unit can comprise an antenna.

The mobile device can in particular be designed as a mobile phone or as a wearable. Communication with the switching device can be via a

Close-range communication, e.g. Bluetooth Low Energy, take place. Preferably, the mobile device can be equipped with a backend system, e.g. B. via a telecommunications network. Expressions such as “communication taking place” or “no communication” refer to whether or not the switching device receives a communication signal from the mobile device. The switching device is preferably designed to receive the communication signal periodically or permanently from the mobile device so that the switching device accepts the communication as taking place. A lack of communication means in particular that the switching device no longer receives a communication signal from the mobile device.

The at least one electrical consumer can, for. B. as air conditioning, as a ventilation system, as a television, as a light source, as a roller shutter motor, as a screen, as a camera, as a projection device, as a sound system or as an electrical device plugged into a socket. If there are several electrical consumers, the electrical consumers can be selected from an air conditioning system, a light source, a roller shutter motor, a television, a screen, a camera, a projection device, a sound system or an electrical device plugged into a socket. It is also conceivable that several electrical consumers z. B. are designed as devices and / or light sources. The switching device enables, in particular by means of the output, that the electrical load can be switched on, e.g. B. via a light switch, a shutter, air conditioning or ventilation system control element. The first state of the electrical consumer can be a de-energized state. In the second state of the electrical consumer, it can be, for. B. be a condition with applied voltage. Consequently In particular, the switching device enables electrical voltage to be applied to the consumer and thus serves to supply the consumer with electrical energy.

It can also be the case that the switching device automatically switches on at least one consumer. For example, an electrical voltage is applied to the consumer in the first and in the second state. This makes it possible for the electrical consumer to be controlled in the first and in the second state. The consumer is then switched on by means of the output. For example, a control signal, e.g. a telegram, to switch on the consumer can be sent via the output. Alternatively, the electrical consumer can be switched up by means of a control signal sent via the output. For example, a consumer, e.g. B. the air conditioning, initially only on a low level. If a control signal is sent via the output, the consumer, e.g. B. the air conditioning, set to a higher level. Thus, the first state can differ from the second state of the electrical consumer by a lower energy consumption or by a low electrical power. In this case, the energy consumption or the electrical power in the first state can also be zero. The output can thus be used to change the energy consumption of the consumer or the electrical power it consumes.

The output is preferably designed as an electrical connection. In particular, the output is designed as a socket or as a terminal.

The switching device, in particular the control device, preferably changes the operating state of the output in order to transfer the consumer from the first state to the second state. In particular, a change in the operating state means that the electrical voltage at the output changes.

It may be that an electrical mains voltage for the electrical consumer can be present at the output. For example, the switching device comprises a switching element for applying an electrical mains voltage to the consumer. The switching element is provided in particular in the switching device. Communication with the mobile device is then a prerequisite for applying the electrical voltage for the consumer to the output by means of the switching element.

Alternatively, it can be provided that the output is used for connection to a control line. A control voltage can be applied to the output. In particular, a direct current or alternating current low voltage for the purpose of control is regarded as the control voltage. The control voltage then causes a switching element, e.g. B. a Relay, outside of the switching device, to apply the electrical voltage to the consumer or to change the energy consumption of the consumer, in particular to increase it.

It may be that the control voltage is applied as long as the consumer remains in the second state. This is particularly the case when an operating current relay is used. It may be that the control voltage is switched off as long as the consumer remains in the second state. This is particularly the case when a closed-circuit relay is used.

A control signal can be sent via the output. Thus, a first control signal, e.g. B. as part of a telegram, in order to transfer the consumer from the first state to the second state. The control signal is only applied for transfer. On the other hand, while the consumer remains in the second state, there is no control signal.

Additionally or alternatively, the switching device, in particular the control device, can change the operating state of the output in order to transfer the consumer from the second state to the first state. In other words, the output is used so that the switching device transfers the electrical load from the second state to the first state. In particular, a change in the operating state means that the electrical voltage at the output changes.

For this purpose, a mains voltage present at the output can be switched off.

For example, a control voltage can be applied to the output, which leads to the mains voltage being switched off outside the switching device. For example, the control voltage for controlling a switching element, e.g. B. a relay, serve. The control signal then causes the switching element, e.g. B. the relay to switch off the electrical voltage to the consumer or to change the energy consumption of the consumer, in particular to lower it.

It may be that the control voltage is applied as long as the consumer remains in the first state. This applies in particular when using a closed-circuit relay. It may be that the control voltage is switched off as long as the consumer remains in the first state. This is particularly the case when an operating current relay is used.

Alternatively, a second control signal, e.g. B. as part of a telegram, in order to transfer the consumer from the second state to the first state. The control signal is only applied for transfer. On the other hand, while the consumer remains in the first state, there is no control signal. In particular, the electrical consumer is not part of the switching device according to the invention. Rather, the invention is to be understood in such a way that the operating state of the output, in particular the voltage present at the output, can be replaced in such a way that the first or the second state of the consumer can be brought about.

The state of the output, in particular the voltage present at the output, depends on whether or not there is communication with the mobile device.

If the communication takes place, the switching device uses the output in such a way that the consumer is transferred to the second state or remains in the second state. If the communication takes place and the consumer is in the first state, the switching device changes the operating state of the output in order to transfer the consumer from the first state to the second state. This applies in particular to the start of communication between the switching device and the mobile device. If the communication takes place and the consumer is already in the second state, the switching device leaves the operating state of the output unchanged. The switching device is set up to initiate a transfer of the consumer from the first state to the second state by means of the output when communication with the mobile device begins.

The switching device can preferably infer the state of the consumer in which the switching device knows the current operating state of the output and / or tracks the change in the operating state. Therefore, statements “when the consumer is in the first or second state” are to be understood to mean that the switching device makes this statement based on the current operating state or the operating state curve. The statement “if the switching device has previously changed the operating state of the output in order to transfer the consumer to the second state” means that the switching device now assumes that the consumer is in the second state. Correspondingly, the statement “if the switching device has previously changed the operating state of the output in order to transfer the consumer to the first state” is to be understood as meaning that the switching device now assumes that the consumer is in the first state.

If there is no communication between the mobile device and the switching device, the switching device uses the output in such a way that the consumer is transferred to the first state or remains in the first state. If there is no communication and the consumer is in the second state, the switching device changes the operating state of the output in order to remove the consumer from the to convert the second state into the first state. If there is no communication and the consumer is already in the first state, the switching device leaves the operating state of the output unchanged.

For this purpose, the switching device preferably acts independently, i. H. no action by a user is necessary for the switching device to change the operating state of the output so that the consumer is transferred to the first state. Thus, the switching device is preferably set up so that, if the switching device has previously changed the operating state of the output in order to transfer the consumer to the second state, and communication with the mobile device fails, the switching device independently changes the operating state of the output, to transfer the consumer from the second state to the first state. This applies in particular to the termination of the communication between the switching device and the mobile device.

In order for the switching device to change the operating state of the output, u to transfer the consumer to the first state, communication must be absent, in particular for a predetermined period of time or for a predetermined number of attempts at communication between the switching device and the mobile device. This prevents a single failure of communication, which, for example, due to an error or due to a brief movement of the mobile device out of the communication area, already leads to the loads being switched off. The switching device determines the predetermined period of time or the predetermined number of communication attempts, in particular on the basis of the last successful communication. The predetermined period of time or the predetermined number of communication attempts can be stored in the memory of the switching device. It is conceivable that an administrator of the switching device can set the time period or the predetermined number.

If the switching device has already initiated the transition to the second state and if the switching device communicates with the mobile device, the switching device will use the output to ensure that the electrical consumer remains in the second state. In this way, a change in the operating state, in particular a change in voltage, can be omitted at the output. So z. B. the mains voltage remain applied to the output or the control voltage applied to the output remain unchanged. The switching device is thus set up so that, if the switching device has previously changed the operating state of the output in order to transfer the consumer to the second state, and the switching device also the mobile device communicates, the switching device leaves the operating state of the output unchanged, so that the consumer remains in the second state.

In this case, it is provided in particular that the switching device only initiates a transfer of the consumer to the first state by means of the output when a predetermined period of time has elapsed, starting from the last successful communication. Starting from the last successful communication, the switching device does not change the operating state of the output until a predetermined period of time has elapsed, in order to transfer the consumer to the first state.

By the predetermined period of time it is, for. B. possible to leave an electrical consumer switched on for the period of time. For example, a ventilation system or an air conditioning system can remain switched on for the period of time while the user has already left the spatial area. In another example, the exit from the spatial area is illuminated by the light sources, although the mobile device is already outside the communication area. The predetermined period of time can be stored in the memory of the switching device. It is conceivable that an administrator of the switching device can set the predetermined time period.

The period of time can preferably be adjustable at least up to an upper limit value. Particularly preferably, the time period can only be set up to an upper limit value. This prevents the desired energy-saving effect from being prevented by setting a long period of time. In particular, the switching device can receive the set period of time from the mobile device, from an access control device or a backend system and store it in an electronic memory of the switching device.

In particular, the switching device receives a communication signal from the mobile device to maintain the communication. A signal strength value with which the switching device receives a signal from the mobile device and recognizes the signal as a communication signal can preferably be set. In this way, different types of mobile devices, in particular mobile telephones from different manufacturers, can be taken into account. For example, a first limit value of the signal strength value that is still recognized as a communication signal is defined for a first type of mobile phone and a second limit value of the signal strength value that is still recognized as a communication signal is defined for a second type of mobile phone. For example, the first limit value can be designed to be higher than the second limit value if the first type of mobile phone transmits stronger signals than the second type. The limit value can be calibratable. For example, the limit value is through the User can be calibrated after communication between the mobile device and the switching device has started. For example, the user is requested to take different distances from the switching device or to visit different areas of the spatial area in order to carry out the calibration.

The switching device can comprise an electronic memory. It is preferably provided that an identifier of the mobile device is stored in the electronic memory, in particular as authorized. If the switching device has previously caused the consumer to switch to the second state and there is no communication between the switching device and the mobile device, the identifier of which is stored in the electronic memory, in particular as authorized, the switching device causes via the output that the consumer changes from the second state to the first state. In other words, if the switching device has previously changed the operating state of the output in order to transfer the consumer to the second state, and there is no communication between the switching device and the mobile device, the identifier of which is stored in the electronic memory, in particular as authorized, so the switching device will change the operating state of the output in order to transfer the consumer from the second state to the first state.

If the switching device has previously changed the operating state of the output in order to transfer the consumer to the second state, and the switching device communicates with the mobile device, the identifier of which is stored in the electronic memory, in particular as authorized, the switching device leaves it as it is the operating state of the output unchanged in order to leave the consumer in the second state.

In this embodiment variant, however, the switching device only behaves accordingly if an identifier of the mobile device is stored in the memory or an identifier of the mobile device is stored in the memory as being authorized. A distinction is hereby made between communications or attempts at communication by the switching device with mobile devices that are not authorized for the consumers to be transferred to the second state or to remain in the second state, and those mobile devices that are authorized to do so. Only if the switching device has recognized the mobile device as authorized is a transfer to the second state initiated on the basis of a communication with the mobile device, or the switching device leaves the consumer in the second state. When communicating or attempting to communicate with an unauthorized mobile device, the switching device leaves the consumer in the first state or transfers the consumer to the first state, unless communication is also taking place with an authorized mobile device.

The mobile device can be recognized as authorized by the fact that the switching device records the identifier in the memory or that the switching device assigns an authorization to the identifier in the memory. For example, with a first communication setup between the switching device and the mobile device, an authorization can be recognized and stored accordingly.

It may be that the switching device is set up to delete the identifier in the electronic memory or to mark it as unauthorized if there is no communication with the mobile device, the identifier of which is stored in the electronic memory. For the determination of a lack of communication, it can be defined that the communication has to be absent for the predetermined period of time or for the predetermined number of attempts at communication between the switching device and the mobile device. The authorization to apply a voltage to the consumer expires in this embodiment of the invention for a user who has once moved out of the communication range with the mobile device. If the user wants to switch on the electrical loads again, the user must first be recognized as authorized by the switching device.

In an alternative, even if there is no communication with the mobile device, the identifier of which is stored in the electronic memory, the identifier remains in the electronic memory or is identified as authorized in the memory. In this embodiment of the invention, the authorization to apply a voltage to the consumers is retained for a user who has once moved out of the communication range with the mobile device. If the user wants to switch on the electrical loads again, the user only needs to get back into the communication range.

It can be provided that the switching device comprises several outputs. The outputs are intended to supply various consumers with electrical energy. For example, one output is used to supply power to a ventilation system and another output is used to supply power to a television. In another example, the electrical equipment of a first desk, e.g. B. a docking station and a desk lamp, supplied by means of a first output, and the electrical devices of a second desk by means of a second output. Thus, each of the outputs can be effectively connected to at least one consumer or a group of consumers. The expression "to change the operating state of the output in order to transfer the consumer to the first or second state" is therefore like that to understand that the change in the operating state of the output is used to transfer the loads that are actively connected or that can be actively connected to the same output into the first or second state.

The switching device can be set up so that, despite communication between the switching device and the mobile device, the switching device leaves the operating state of the output unchanged in order to leave the consumer in the first state. In other words, selectivity can be provided. The communication with the mobile device does not automatically lead to all loads that are actively connected to the switching device being transferred to the second state. Rather, it is possible that consumers also remain in the first state. This can be provided in particular if several users share a hotel or dormitory room. For example, a child can turn on the ventilation system but not the television, while an adult can turn on both. On the other hand, a first user can use a first docking station and a second user cannot.

It is conceivable that different mobile devices are assigned to different outputs. The selectivity can be established by means of this assignment. The assignment can be stored in the switching device. By means of the assignment, consumers who are not assigned to the mobile device remain in the first state. For example, the child's mobile device may be assigned to the outlet for the ventilation system but not the outlet for the television.

If the switching device communicates with the mobile device, the switching device is preferably designed to change the operating state of that output or those outputs that are assigned to the mobile device that communicates with the switching device in order to put a consumer in the second state to convict. This applies in particular to the establishment of communication between the switching device and the mobile device. If the switching device communicates with the mobile device, the switching device is preferably designed to maintain the operating state of the output in order to leave a consumer in the second state. In contrast, the operating state of that output or those outputs that are not assigned to the mobile device that communicates with the switching device is retained in order to leave a consumer in the first state.

The switching device is preferably set up to communicate with a plurality of mobile devices via the communication device. If there is no communication between the switching device and each of the multiple mobile devices, the switching device automatically changes the operating state of the output or outputs in order to transfer the consumer or consumers from the second state to the first state. If there is no communication between the switching device and each of the multiple mobile devices recognized as authorized, the switching device preferably independently changes the operating state of the output or outputs in order to transfer the consumer or consumers from the second state to the first state. It is preferably provided that when all users or all users recognized as authorized have left the room, the consumers are transferred to the first state. In particular, all consumers are transferred to the first state.

In particular, communication has to be absent for a predetermined period of time and / or for a predetermined number of attempts to communicate with the switching device with all mobile devices or with all mobile devices recognized as authorized before the operating state of the output or outputs is changed to transfer the consumer to the first state will.

The switching device can wait the predetermined period of time before the operating state is changed.

It may be that different predetermined time periods are stored in the switching device for different outputs. It is thus conceivable that the switching device changes the operating state of a first output at the end of a first period in order to transfer a consumer to the first state. In contrast, the switching device changes the operating state of a second output at the end of a second period of time in order to transfer a consumer to the first state. The first time period can differ from the second time period. A time period can thus be assigned to one or more outputs, in particular to each output.

If the switching device has previously changed the operating state of the output in order to transfer the consumer to the second state, the switching device leaves the operating state of the output unchanged if communication with only one of the multiple mobile devices takes place. If the switching device has previously changed the operating state of the output in order to transfer the consumer to the second state, the switching device preferably leaves the operating state of the output unchanged when communication is taking place with only one of the several authorized mobile devices. As a result, the consumer remains in the second state. Thus, the individual mobile devices or the individual devices recognized as authorized are with a logical “OR” in the switching device connected. I. E. a single mobile device or a single authorized mobile device is sufficient to keep the consumer in the second state. This applies above all to a single output or to a lack of selectivity for several or all outputs.

In the case of selectivity, on the other hand, the following preferably results:

If the switching device has previously changed the operating state of several outputs in order to transfer the loads to the second state, and the switching device communicates with a first of the plurality of mobile devices, whereas the communication of the switching device with a second of the communication devices ends, the switching device changes the operating state of the output or outputs that are assigned to the second mobile device, but not to the first mobile device, in order to transfer the corresponding consumers to the first state. In contrast, the operating state of that output or outputs that are assigned to the first mobile device remains unchanged. In particular, the outputs that are assigned to the first mobile device remain unchanged, regardless of whether these outputs are also assigned to the second mobile device or not.

It can be provided that a first command from the mobile device can be received by the switching device. The switching device changes the operating state of the output on the basis of the first command in order to transfer a consumer from the second state to the first state. The first command can in particular be generated by a conscious action by the user on the mobile device. It is thus conceivable that, in addition to the automatic transition to the first state, if the communication connection breaks off, the first state can also be brought about by a conscious decision by the user. This can e.g. B. be helpful when falling asleep in a strange hotel room if the light switches are difficult to find or operate.

It may be that a second command from the mobile device can be received by the switching device. On the basis of the second command, the switching device changes the operating state of the output in order to transfer a consumer from the first state to the second state. The second command can in particular be generated by a conscious action by the user on the mobile device. In particular, the second command is only intended to cancel the first command. The second command, on the other hand, is not provided in order to prevent the consumers from switching off automatically if communication is interrupted. The object of the invention is also achieved by a device with a switching device according to the invention and with a mobile device. The switching device can in particular be designed as in one of claims 1 to 15. Features and details that are described in connection with the switching device according to the invention also apply in connection with the device according to the invention and vice versa.

It is preferably provided that the frequency of the, in particular periodic, communication between the switching device and the mobile device is variable.

For example, this should not unnecessarily reduce the charging of an energy store in the mobile device.

The mobile device preferably comprises an acceleration sensor. If there is no signal or if there are no signals from the acceleration sensor, the frequency of communication is preferably reduced. The acceleration sensor is an indicator of a movement of a user and thus an indicator of a possible break in communication between the switching device and the mobile device. If signals from the acceleration sensor are missing, the mobile device is not moved, e.g. B. when the user is sleeping or doing a fixed activity such as reading or desk work.

Additionally or alternatively, the device, i. H. the switching device and / or the mobile device comprise an acoustic or vibrating warning device, by means of which a warning can be output if an energy store of the mobile device falls below a charge value. The warning can in particular be provided if at the same time a signal from the acceleration sensor is missing. This prevents the energy store of the mobile device from being empty to such an extent that communication with the switching device is prevented. Since the sockets are also de-energized in this case, recharging of the mobile device is also prevented.

It may be that the device according to the invention comprises a plurality of switching devices which communicate with a mobile device. This can be provided if several switching devices are arranged in the spatial area in order to supply various loads with electrical voltage. For example, the outputs of a switching device are not sufficient to supply the loads with electrical voltage. For example, it can be provided that one or each switching device comprises only one output. The respective switching devices can be designed as described above. The object of the invention is also achieved by an access control system with a switching device according to the invention and with an access control device. The switching device can in particular be designed as in one of claims 1 to 15. Features and details that are described in connection with the switching device according to the invention also apply in connection with the access control system according to the invention and vice versa. Optionally, the access control system can comprise the mobile device and / or comprise several switching devices according to the invention. The switching devices can each communicate with the same access control device.

It is preferably provided that the access control device checks an access authorization of the mobile device and only if an access authorization is present, a transition from the first state to the second state is possible by means of the output. A positive result of the access authorization check is a prerequisite for the switching device to change an operating state of the output in order to cause a change from the first state to the second state. It can thus be that the mobile device is recognized by the switching device as authorized to transfer consumers to the second state and / or is stored in the switching device if the access authorization check was previously concluded with a positive outcome.

The positive result of the access authorization check enables the user to access a previously blocked spatial area, preferably a room in a building, particularly preferably a hotel or dormitory room. The access control device is assigned to the spatial area. The access control device serves in particular as a permanently installed guard for the spatial area. The access control device may be an electromechanical device, e.g. An electric motor or solenoid, or an electromagnetic device by means of which the user can gain access to the physical area. The access control device can in particular be designed as an electromechanical fitting, as an electromechanical lock cylinder, as an electromechanical door opener, as an electromechanical door closer or as a motor lock.

In the event of a positive result of the access authorization check, the access control device grants access to the spatial area. In the event of a negative result of the access authorization check, the access control device denies access to the spatial area. The access control device can comprise an electronic processor or controller in order to carry out the access authorization check.

The access control device is preferably designed for checking access authorization of various access attributes, in particular access attributes of different users. The access attributes of different users can be checked in the same period with a positive result. I. E. In the same period of time, several users are authorized to access the spatial area. For example, a married couple is quartered in a hotel room or several students share a dormitory room. Each user has their own access attribute, e.g. B. an access code assigned. The access attributes are in particular each stored in the mobile device of the different users.

The access control device is particularly preferably designed for wireless communication with the mobile device which includes the access attribute.

The access control device can receive the access attribute from the mobile device, in particular wirelessly. The access control device checks the access attribute in the access authorization check. If there is a positive result of the access authorization check of the access attribute, the access control device grants access to the spatial area. If there is a positive result of the access authorization check of the access attribute, the access control device sends a message to the switching device and / or to the mobile device. The switching device and the mobile device are preferably enabled by the message to be able to communicate with one another. For example, the switching device and the mobile device go into a pairing mode.

For example, the access control device transmits an identifier of the mobile device to the switching device as a message, so that the switching device can select the mobile device that has been verified as authorized. It may be that the access control device transmits an identifier of the switching device to the mobile device, so that the mobile device can select the switching device.

It is conceivable that the operating state of the output is only changed at the end of a delay period after the positive result of the access authorization check or after communication has been established between the mobile device and the switching device in order to transfer the consumer from the first state to the second state. This means that the application of voltage to the consumer is delayed.

Here, the delay period can be predetermined, in particular adjustable, predetermined. The delay period can be stored in the memory of the switching device. For example, an administrator is authorized to change the delay period and to store it in the memory of the switching device. If several outputs are provided, different delay periods can be provided for the individual outputs be. The delay periods assigned to the outputs are stored in particular in a memory of the switching device.

The access control device and the switching device preferably each have their own housing. In particular, the access control device is intended to be arranged outside the spatial area. The switching device, on the other hand, is provided to be arranged in the spatial area.

The access control device and the switching device preferably communicate with one another. In particular, the access control device notifies the switching device that an access authorization check has been concluded with a positive result.

For the communication, the access control device comprises a first communication means and the switching device comprises a second communication means. The access control device and the switching device communicate with one another, in particular wirelessly, by means of the first and second communication means. Alternatively, the switching device comprises an input for wired communication with the access control device.

It may be that the access control device notifies the switching device of the access attribute or an identifier assigned to the access attribute as a message after the positive result of the access authorization check.

It may be that the access control device has knowledge of at least one or more parameters before the message is sent.

The assignment of the access attribute or the mobile device to the exits, a delay period, several delay periods allocated to the exits, the predetermined period of time, the predetermined number of communication attempts, a period of time, several periods of time allocated to the exits and / or the signal strength value can be provided as parameters.

It may be that the switching device has no current parameters or only partially current parameters before the message is sent.

For example, the access control device is in communication with a backend system, via which the update takes place. It may be that the access device of the switching device sends at least one parameter or several parameters, e.g. B. as part of the message.

It may be that at least one parameter or several parameters are part of the access attribute. It is conceivable that the access control device the at least one Receives parameters from the mobile device as part of the access attribute. The mobile device can have previously received the access attribute from the backend system.

Alternatively, it can be provided that communication between the access control device and the switching device takes place, in particular exclusively, via the mobile device. In this alternative, it is conceivable that there is no direct communication between the access control device and the switching device. Rather, the access control device and the mobile device communicate wirelessly with one another. The switching device and the mobile device also communicate wirelessly with one another. The access control device sends the message to the mobile device, which then begins communication with the switching device.

In this case, at least one parameter can be sent from the mobile device to the switching device. The assignment could previously from the backend system in the mobile device, e.g. B. as part of the access attribute. Alternatively, the access control device can send the assignment to the mobile device, the mobile device sending the assignment to the switching device.

It is conceivable that the switching device sends a change in the operating state of the output or the outputs to the access device and / or to the mobile device. It can also be the case that the switching device independently determines the length of time during which a consumer was in the second state. The switching device can transmit the length of time to the access control device and / or to the mobile device. This information is preferably transmitted to the backend system by the access control device or the mobile device. This allows an administrator to settle, e.g. B. for the user, create or recognize the useful life or the type of use of the spatial area.

It is preferably provided that the switching device sends this information only when requested by the mobile device and / or the access control device. It is conceivable that the switching device sends the termination of a communication with the mobile device to the access control device. The access control device can, for. B. send the termination of a communication with the mobile device to a backend system.

The object of the invention is also achieved by a method for transferring an electrical load from a second state to a first state. Features and details that are described in connection with the method according to the invention also apply in connection with the switching device according to the invention, the device according to the invention, the access control system according to the invention and vice versa. The features mentioned in the description and in the claims can each be essential to the invention individually or in combination. In particular, a switching device, a device and an access control system with which the method according to the invention, in particular the method according to claim 18, can be carried out, as well as a method that can be carried out with the switching device according to the invention, in particular with a switching device according to one of claims 1 to 15, or with a device according to the invention, in particular with a device according to claim 16, or with an access control system according to the invention, in particular according to claim 17.

The method is carried out by the switching device. The switching device comprises at least one output. The output is used to change from a second electrical state of the electrical consumer to a first electrical state of the electrical consumer. The switching device comprises a communication device for wireless communication with a mobile device.

The switching device (3) carries out the following method steps according to the invention:

• Change of an operating state of the output in order to transfer the consumer from the second state to the first state.

Here, the switching device will in particular first determine that the communication between the switching device and the mobile device has ended. I. E. there is no communication. The switching device will then change the operating state of the output in order to transfer the consumer from the second state to the first state

The invention is explained in more detail below on the basis of exemplary embodiments. Technical features with the same function are provided with identical reference symbols in the figures. Show it:

FIG. 9 shows an alternative spatial area as an application for the access control system according to the invention in accordance with the second exemplary embodiment.

A spatial region 50 is shown in FIG. The spatial area 50 is designed, for example, as a hotel room and is divided into a wet area 51 and a sleeping area 52 with a bed 53. The spatial area 50 is closed with a door 54. The door 54 can only be opened from the outside if the user is authorized to do so.

In addition, an access control system 1 according to the invention is shown in FIG. The access control system 1 according to the invention comprises an access control device 2 and a switching device 3 according to the invention the switching device 3 is enabled.

The access control device 2 is arranged on the outside of the door 54. The access control device 2 can be designed, for example, as an electromechanical door fitting. If the user is authorized to enter, the electromechanical door fitting enables the user to retract a locking element of a door lock that keeps the door 54 closed and thus to open the door 54. The access control device 2 determines whether the user is authorized by the access control device 2 receiving an access attribute from a mobile device 10 assigned to the user. The wireless communication between the mobile device 10 and the access control device 2 is represented by the symbol of the triple arrow. The mobile device 10 is designed as a mobile phone. The access attribute is stored in the mobile device 10. The access attribute can e.g. B. include an access code. The access attribute can alternatively or additionally be designed as at least one period of time in which the user is authorized to enter.

The access control device 2 carries out an access authorization check in which the access control device 2 checks the access attribute. If the access authorization check is completed with a positive result, the user is authorized to enter. If the access authorization check is concluded with a negative result, access is denied, i. H. the electromechanical door fitting prevents the user from pulling back the locking element.

Several electrical loads 20 are arranged in the spatial area. The consumers 20 are, for example, a ventilation system 21, a reading lamp 22 and a television 23. The consumers 20 are in a first state, which is denoted by “X” in the figures. In the first state, the loads 20 are de-energized. I. E. even if a person located in the spatial area 50 were to operate a light switch of the reading lamp 22, a remote control of the television 23 or a controller of the ventilation system 21, the electrical consumer 20 would not be able to be switched on.

The switching device 3 according to the invention is also located in the spatial area. For example, the switching device 3 is arranged in a flush-mounted box in a wall of the spatial area.

According to the invention, it is provided that the switching device 3 comprises a communication device with which the switching device 3 can communicate wirelessly with the mobile device 10. The communication device is designed as a transmitting and receiving unit 32.

A schematic structure of the switching device 3 is shown in FIG. The switching device 3 comprises a housing 31. The transmitting and receiving unit 32 is arranged in the housing 31 in order to communicate wirelessly with the access control device 2 and the mobile device 10. The switching device 3 further comprises a controller 33 with a processor and a memory as a control device. The switching device comprises a timer in order to be able to determine time intervals. The switching device 3 comprises an output 34. An electrical voltage can be applied to the output. The output is designed as a socket.

As an alternative and not shown, a transmitting and receiving unit 32 is used for wireless communication with the mobile device 10, while the switching device 3 comprises an input in order to communicate with the access control device 2 in a wired manner.

In both cases, the access control device 2 has a first communication means, be it a transmitting and receiving unit (not shown) or be it an output, in order to communicate with the switching device. The switching device 3 comprises a second communication means, designed as a transmitting and receiving unit 32 or as an input in order to communicate with the access control device 2.

As a result of the positive result of the access authorization check of the switching device 3, the access control device 2 transmits an identifier of the mobile device 10, the access attribute of which has led to the positive result of the access authorization check. The identification is transmitted as a wireless transmitted message. Here, the access control device 2 and the switching device 3 communicate wirelessly with one another.

The access control device 2 transmits an identifier of the switching device 3 to the mobile device 10. The mobile device 10 and the switching device 3 then go into a pairing mode and start wireless communication with one another.

Alternatively, the access control device 2 can only transmit an identifier of the mobile device 10 to the switching device 3 so that the switching device 10 starts wireless communication with the mobile device 10. In a further alternative, not shown, the access control device 2 and the switching device 3 do not communicate with one another. Rather, the access control device 2 transmits the identifier of the switching device 3 to the mobile device 10, so that the mobile device 10 can start a communication with the switching device 3.

Starting the wireless communication between the switching device 3 and the mobile device 10 is a prerequisite for an electrical voltage to be applied to the loads 20. As soon as the mobile device 10 and the switching device 3 are in mobile communication, an electrical voltage is changed, in particular applied, at the output 34 of the switching device 3. The operating state of the output 34 is thus changed. As a result, the consumers are also supplied with electrical voltage and thus transferred to the second state. If the light switch of the reading lamp 22, the remote control of the television 23 or If the controller for the ventilation system 21 is actuated, the reading lamp 22, the television 23 or the ventilation system 21 are switched on. This state is shown in Figure 2 with a symbolic tick on the consumers.

On the one hand, it is conceivable that the output 34 is part of circuits with the electrical loads 20. Thus, for the transition from the first state to the second state, the mains voltage, e.g. B. 220 V, applied to the output 34. Alternatively, a control voltage can be applied to output 34, e.g. E.g. 6 V, 12 V, 27 V or 34 V, e.g. B. to switch a relay outside the switching device 3. The application of the control voltage is understood as a change in the operating state of the output 34. The control voltage is changed in such a way that the relay stops interrupting the circuits with the loads 20. For example, a voltage is applied to output 34 so that current flows through the relay in order to switch an operating current relay. Alternatively, the voltage is switched off so that a current flow through the relay is interrupted in order to switch a closed-circuit relay. In both cases, an electrical voltage is applied to the loads 20 as a result.

The switching device 3 periodically checks whether the mobile device 10 is in the vicinity. To this end, the switching device 3 checks whether the mobile device 10 is within the communication range. To this end, the switching device 3 communicates with the mobile device 10. The communication range is set and the switching device 3 is arranged in the spatial area such that the mobile device 10 is within the communication range as long as the mobile device 10 is in the spatial area 50 . In contrast, the mobile device 10 will soon be outside the communication range if the mobile device 10 is outside the spatial area 50.

If the mobile device 10 is within the communication range, the consumers 20 remain in the second state. The operating state, ie the voltage state, at the output 34 does not change. If, on the other hand, the switching device 3 can no longer discover the mobile device 10 within the communication range, the switching device 3 changes the voltage applied to the output 34 and thus the operating state of the output 34 so that the loads return to the first state. The consumers 20 can therefore no longer be switched on. For this purpose, either the mains voltage is taken from the output 34 or the control signal is changed at the output 34. In the case of an operating current relay, the control voltage is switched off so that the operating current relay no longer has current flowing through it. In the case of a closed-circuit relay, the control voltage is switched on so that the The shunt relay is no longer carrying current. In both cases the electrical circuits of the consumers are interrupted.

The switching device 3 recognizes whether the mobile device 10 is within the communication range from the fact that the switching device 3 receives a communication signal from the mobile device 10 periodically or continuously. A signal strength value with which the switching device 3 receives a signal from the mobile device and recognizes the signal as a communication signal is preferably adjustable. Here, the switching device 3 can receive the signal strength value as a parameter from the mobile device 10 or the access control device 2. Alternatively, the signal strength value can be determined by a calibration method. Here, the user can, for. B. reside at different points in the spatial area 50. The mobile device 10 determined the various signal strengths and defines a signal strength value as a limit value.

The frequency with which the switching device requests a communication signal from the mobile device 10 can vary. As a result, the electrical power of the mobile device 10 can be reduced and thus the state of charge of an energy store of the mobile device can be spared. The frequency of the communication depends on whether, when and / or how often an acceleration sensor of the mobile device 10 emits a signal. The acceleration sensor can be used to determine whether the user is moving and thus there is a risk that the user will soon be outside the communication range. If, on the other hand, the acceleration sensor does not send a signal, the user will behave in a stationary manner, e.g. B. sit at a desk or sleep. The mobile device 10 can use the signal from the acceleration sensor to determine the desired frequency of communication attempts and to communicate it to the switching device 3. The switching device 3 will then request a communication signal from the mobile device 10 at the frequency received.

Furthermore, the mobile device 10 will emit an acoustic and / or vibratory warning signal if the state of charge of the energy store has decreased too much.

In order to reduce the susceptibility to errors, a single failure of communication is not enough to transfer the loads 20 to the first state. Rather, unsuccessful communication attempts and / or a predetermined number of unsuccessful communication attempts must be present for a predetermined period of time so that the switching device 3 recognizes the communication as terminated and initiates the transition to the first state. In addition, for example, the ventilation system 21 should continue to run for a period of time after the communication has ended. For this purpose, a period of time is stored in the switching device 3 for how long the transition to the first state is to be delayed, starting from the termination of the communication. Only at the end of the period after the communication between the switching device 3 and the mobile device 10 has ended, the switching device 3 causes the loads 20 to be transferred to the first state by means of the output 34.

The user also has the option of actively entering a first command on the mobile device 10. The mobile device 10 sends a first command to the switching device 3. If the switching device 3 receives the first command, the switching device 3 will change the operating state of the output 34 in such a way that the loads 20 are transferred to the first state. This allows the user z. B. in a strange hotel room the search for switches for consumers 20 are spared. By entering a second command, the user can switch on the consumer 20 again by the switching device 3 receiving the second command and transferring the consumer 20 to the second state. The second command is only executed if the signal strength value with which the switching device 3 receives a signal from the mobile device and recognizes the signal as a communication signal is observed.

A further variant of a switching device 3 of the access control system 1 according to the invention is indicated in dashed lines in FIG. 6. In this variant, the switching device 3 has a further output 35. The further output 35 is provided in order to be able to transfer the loads 20 from the first state to the second state at different times. For example, the ventilation system 21 should only be transferred from the first to the second state at the end of a delay period that begins with the establishment of communication between the mobile device 10 and the switching device 3. In contrast, the remaining loads 22, 23 should be transferred from the first to the second state immediately after communication has been established between the mobile device 10 and the switching device 3. For this purpose, the circuits of the loads 22, 23 can be switched via the first output 34, while the circuit of the ventilation system 21 can be switched via the second output 35. For example, a control voltage can be applied to the output 34, which switches a relay of the circuits of the loads 22, 23. A control voltage, which switches a relay in the circuit of the ventilation system 21, can be applied to the output 35. The different outputs 34, 35 can also be used to switch off the consumer 21 on the one hand and the consumers 22, 23 on the other hand again with different durations.

The delay period or periods of delay, the period or the plurality of periods of time, the predetermined period of time and / or the predetermined number of communication attempts can be configurable by an administrator of the access control system 1. The delay period, the predetermined period of time, the predetermined number of communication attempts and / or the duration can be stored in the controller 33. The administrator can change the delay period, the predetermined period of time, the predetermined number of communication attempts and / or the period of time in a configuration mode of the switching device 3. It is possible, however, that the administrator can only change the duration up to a limit value in order not to endanger the energy savings achieved by the switching unit.

The switching device 3 can determine the length of time with which the consumers remained in the second state. Here, the switching device 3 has an operating state curve over time. I. E. the switching device 3 has stored in the memory when an operating state change of the output 34 or the outputs 34, 35 has occurred. The switching device 3 transmits the length of time to the mobile device 10 and / or to the access control device 2. The mobile device 10 or the access control device 2 send the length of time to the backend system.

A further access control system 1 according to the invention with a switching device 3 according to the invention is shown in use in FIGS. 3 to 5. Unless otherwise described, the second exemplary embodiment corresponds to the first exemplary embodiment.

The spatial area 50, e.g. B. a dorm room is occupied by several users. For this purpose, a second bed 55 is located in the spatial area 50. In addition, a further reading lamp 24 with a light switch is provided as a further electrical consumer 20. Alternatively and not shown, two desks with desk lamps and docking stations can also be arranged in the spatial area.

In Figure 7, a switching device 30 is shown for the second embodiment. The switching device has its own output 34, 35, 36, 37 for each consumer 20. For example, the output 34 is used to bring about a change of state for the consumer 21. The output 35 is used to bring about a change of state for the consumer 22. The output 36 is used to bring about a change of state for the consumer 23. The output 37 is used to bring about a change of state for the consumer 24. Alternatively and not shown, one can be used for several consumers common output can be provided. For example, the output 35 can be provided for a reading lamp 22, for a desk lamp and a docking station. The output 37 can be provided for the other reading lamp 24, for the other desk lamp and the other docking station.

A state similar to that shown in FIG. 2 is shown in FIG. An access authorization has been determined on the basis of the access attribute of the mobile device 10. The switching device 3 has started communication with the mobile device 10. As a result, the consumers 21, 22, 23 have been transferred from the first state to the second state. For this purpose, the voltage applied to the outputs 34, 35, 36 was changed. In contrast to the first exemplary embodiment, however, no voltage change was made at the output 37 due to the access authorization and the establishment of communication between the mobile device 10 and the switching device 3. It is therefore not possible for the user to whom the mobile device 10 and the corresponding access attribute are assigned to switch on the reading lamp 24. Even if the mobile device 10 is authorized and is in the spatial area 50, this does not result in the consumer 24 being transferred from the first state to the second state. The switching device thus selectively brings about a change in the state of consumers 20.

In order to be able to act selectively in this way, the memory of the switching device 3 stores which outputs 34, 35, 36, 37 are assigned to which mobile device 10 or which access attribute. For this purpose, an identifier which identifies the mobile device 10 or the access attribute can be stored in the switching device 3. The outputs 34, 35, 36, 37 to be switched are stored for the respective identifier.

An administrator of the access control system can change the assignment. The assignment can thus be configured. For example, an administrator can enter a change in the assignment on a backend system.

The backend system can e.g. B. are in communication with the access control device 2 and receive an update on the assignment. The access control device 2 can send the update to the switching device 3.

In a further example, the backend system communicates with the mobile device 10 and transmits the assignment to the mobile device 10. For example, the assignment can be part of the access attribute that the mobile device receives from the backend system, for example from a cloud. This has the advantage that the assignment is always as current as the access attribute.

For example, the access device 2 receives the assignment from the mobile device 2 and then transmits the assignment in the case of an access authorization the switching device 3. It may be the case that the access device 2 first has to decipher the assignment. In an alternative, the mobile device 10 transmits the assignment to the switching device 3, in particular while the communication is being established.

In addition to or instead of the transmission of the assignment, the delay period or several delay periods assigned to the outputs, the predetermined time period, the predetermined number of communication attempts, a time period, several different time periods assigned to the outputs and / or the signal strength value can be transmitted on these different communication paths.

In FIG. 4, a further user is staying with a further mobile device 11 in the spatial area 50. If this user has reached the spatial area 50 without having an access authorization check carried out by the access control device 2 (not shown), the state of the electrical loads 20 still corresponds to the state shown in FIG. The switching device 3 has not recognized the user of the mobile device 11 as being authorized. In FIG. 4, however, the further user has initially had an access authorization check carried out by the access control device 3 by means of the further mobile device 11. The access authorization check of the access attribute of the further mobile device 11 was concluded with a positive result. The switching device 3 was informed of this positive result. Thus, the switching device 3 has now recognized the user of the mobile device 11 as authorized. Communication between the mobile device 11 and the switching device 3 has started.

The switching device 3 has knowledge or has just gained knowledge of which outputs 34,

35, 36, 37 of the mobile device 11 or the access attribute of the mobile device 11 are assigned. For this purpose, an identifier which identifies the mobile device 11 or the corresponding access attribute is stored in the switching device 3. The outputs 34, 35, 36, 37 to be switched are stored for the respective identifier.

The switching device 3 now changes the voltage at those outputs that are assigned to the mobile device 11, but not to the mobile device 10. In the exemplary embodiment, this is output 37. As a result, consumer 24 is also transferred from the first state to the second state. This allows the other user to switch on his reading lamp 24. The assignment of the outputs to the mobile device 11 takes place by transmission from the mobile device 11 to the access control device 2 or to the switching device 3.

In FIG. 5, the user with the mobile device 10 has left the spatial area 50 in such a way that the mobile device 10 is outside the communication area with the switching device 3 is located. The switching device 3 now changes the voltage at all those outputs that are only assigned to the mobile device 10, but not to the mobile device 11. This results in a voltage change at output 35. As a result, the reading lamp 22 is de-energized so that the user of the mobile device 10 can no longer switch on the reading lamp 22. If the reading lamp 22 was switched on, it goes out.

If the user with the mobile device 11 now also leaves the spatial area 50, the loads 21, 23 and 24 are also de-energized. For example, however, the period of time for the ventilation system 21 is waited until the output 34 and the ventilation system are switched off.

The identifier of the mobile device 10, 11 that has left the spatial area 50 can, in a first alternative, be deleted in the memory of the switching device 3 or marked as authorized. If the user with the mobile device 10, 11 would like to apply voltage to the loads 20 again after entering the spatial area 50, the user must first carry out the access authorization check again.

In an alternative, the identifier of the mobile device 10, 11 remains stored in the memory or is identified as being authorized to switch on at least one consumer 20 when the mobile device 10, 11 has ended communication with the switching device. If the user with the mobile device 10, 11 would like to apply voltage to the loads 20 again after entering the spatial area 50, a new access authorization check is not necessary.

In a further alternative, various control signals, e.g. B. as part of a telegram, can be applied to output 34. For example, the ventilation system 21 can be operated with several power levels, the power levels corresponding to the different electrical power of the ventilation system. It may be that the change from the first state to the second state does not correspond to the application of a voltage, rather a control unit of the ventilation system 21 is always under voltage. The change from the first state to the second state corresponds to the change from a state with a low energy consumption or a low electrical power to a state with a higher energy consumption or a higher electrical power. It may be that different control signals can be applied to the output 34, the control signals each causing the ventilation system to operate at different power levels. When the switching device 3 starts communicating with the first mobile device 10 in FIG. 3, the ventilation system 21 is switched on and operated at a first power level. When the switching device 3 starts communicating with the second mobile device 10 in FIG. 4, while communication between the switching device 3 and the first mobile device 10 is maintained at the same time, the switching device 3 triggers the ventilation system 21 to operate in a second, higher power level. For this purpose, a corresponding control signal is applied to output 34. Starting from the state in FIG. 3, this change of state can again be described as a change from a first state to a second state. If the initial state is added before communication is established with the first mobile device, there is a change from a second state to a third state.

If one of the mobile devices 10, 11 comes out of the communication area of the switching device 3 again, as shown in FIG. 5, the switching device 3 causes a reduction to the first power level of the ventilation system in that the switching device 3 applies a corresponding control signal to the output 34. If both mobile devices 10, 11 have left the communication area, the ventilation system 21 may be switched off after a period of time.

Whether and what a delay period or a period of time is used by the switching device 3 can be determined for each mobile device 10, 11 and for each output 34, 35, 36,

37 be individually different. An administrator can configure it accordingly.

So z. For example, it can be provided that the reading lamps 22, 24 are transferred from the first to the second state without a delay period. It may be that the television 23 is transferred from the first to the second state without a delay period when a communication is established between the switching device 3 and the first mobile device 10. In contrast, the television is only transferred from the first to the second state at the end of a first delay period when communication is established between the switching device 3 and the second mobile device 11. The ventilation system 21 is transferred from the first to the second state with a second delay period after communication has been established between the switching device 3 and the first mobile device 10. The ventilation system 21 experiences a new change of state with a third delay period after communication has been established between the switching device 3 and the second mobile device 11. The first, second and third delay periods can have different lengths. In Figure 8, a further embodiment of an access control system 1 according to the invention is shown. Unless otherwise described, the access control system 1 corresponds to that of FIGS. 3 to 5. Deviating from this, it is provided that the access control system 1 comprises ^{a first switching device 3 and a second switching device 3 '.} The first switching device 3 essentially corresponds to the switching device 3 shown in FIG. 7, but the output 37 for the consumer 24 is missing. The second switching device 3 ^' is designed like the switching device 3 in FIG. The output 34 of the second switching device 3 ^′ is provided for the consumer 24. Thus, it is sufficient for the mobile device 10 to communicate with the switching device 3 in order to cause a change in the operating state of the outputs assigned to the mobile device 10 or its access attribute to transfer the loads 21, 22, 23 to the second state. The mobile device 11, on the other hand, has to ^{communicate with the first switching device 3 and the second switching device 3 'in} order to cause a change in the operating status of the outputs assigned to the mobile device 11 or its access attribute to transfer the loads 21, 23, 24 to the second status.

In a variant of FIG. 8, which is not shown, the first switching device 3 corresponds to the switching device of FIG. 6. The output 34 of the first switching device 3 is provided for the consumer 22. The consumers 21, 23 can also be switched on for unauthorized users independently of the access control system 1. I. E. the consumers 21, 23 are not operatively connected to the switching devices 3, 3 ^'. As a result, the individual switching devices 3, 3 ^'may lack selectivity. In this variant, the mobile device 11 only has to ^{communicate with the second switching device 3 '} , but not with the first switching device 3, in order to be able to use the spatial area 50 as intended. The access control device 2 selectively initiates the corresponding communication between the mobile device 10 and the first switching device 3 and the mobile device 11 with the second switching device 3 ^' by sending corresponding messages.

FIG. 9 shows a further application for an access control system 1 according to the invention. Unless otherwise described, the access control system 1 corresponds to that of FIGS. 3 to 5.
