Definitions
- the invention relates to an access control system according to the preamble of claim 1.
- the access control system comprises at least one switching device for supplying at least one consumer with electrical energy.
- the switching device comprises at least one output. The output is used to change a first electrical state of the consumer into a second electrical state of the consumer.
- the access control system also includes an access control device.
- the access control device carries out an access authorization check to a spatial area.
- the access control system is designed such that 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 of the consumer.
- a functional interaction of the access control device and the at least one switching device is thus provided. Only when the access control device has first completed the access authorization check with a positive result can the switching device then enable the electrical consumer to be supplied with electrical power.
- the fact that the user must have access authorization increases security. A This is because unauthorized users cannot use the spatial area guarded by the access control device due to a lack of power supply. It is excluded that a user who has no access authorization can consume energy or use electrical consumers in the spatial area. This controls the energy consumption particularly well. According to the invention, the energy consumption is linked to the access authorization of the user.
- 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, office 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 is preferably intended to be arranged close to 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 comprise a handle which can be operatively connected to a lock by means of the electromechanical device.
- the access control device can actuate a locking element, in particular a bolt and / or a latch, by means of the electromechanical device.
- the access control device can allow a building door to be opened by means of the electromechanical or electromagnetic device.
- 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.
- the access control device can comprise an electronic processor or controller in order to carry out the access authorization check.
- the access control device can comprise an electronic memory.
- the switching device may comprise an electronic processor or controller.
- the switching device can comprise an electronic memory.
- the output is preferably designed as an electrical connection.
- the output is designed as a socket or as a terminal.
- an electrical voltage can be applied to the output.
- the at least one electrical consumer can, for. B. as air conditioning, as a ventilation system, as television, as a screen, as a camera, as a projection device, as a sound system, as a light source, as a roller shutter motor 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 projection device, a sound system, a camera or an electrical device plugged into a socket. It is also conceivable that several electrical consumers z. B.
- 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 voltage-free state.
- the second state of the electrical consumer it can be, for. B. be a condition with applied voltage.
- the positive result of the access authorization check is a prerequisite for the application of an electrical voltage to the electrical consumer by the switching device.
- the switching device enables electrical voltage to be applied to the consumer and thus serves to supply the consumer with electrical energy.
- the switching device automatically switches on at least one consumer.
- an electrical voltage is applied to the consumer in the first and in the second state.
- a control unit of the electrical consumer is functional in the first and in the second state.
- the consumer is then switched on by means of the output, the positive result of the access authorization check being a prerequisite for switching on the electrical consumer.
- a control signal e.g. B. a telegram can be sent to switch on the consumer.
- the electrical consumer can be switched up by means of a control signal sent via the output.
- the consumer runs e.g. B. the air conditioning, initially only at a low power level.
- a control signal is sent via the output that automatically the consumer, e.g. B. the air conditioning, set to a higher power level.
- the first state can thus differ from the second state of the electrical consumer in terms of lower energy consumption or lower electrical power.
- the energy consumption in the first state can also be zero.
- the positive result of the access authorization check is a The prerequisite is to increase the consumer's energy consumption or the electrical power consumed.
- the access control system can be designed in such a way that a positive result of the access authorization check is a prerequisite for changing the voltage present at the output.
- a change in voltage can also mean that no voltage was previously applied.
- 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 changed in such a way that the first or the second state of the consumer can be brought about.
- a change in the operating state means that the electrical voltage at the output changes.
- the switching device can preferably infer the state of the consumer in that 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” or the statement that “the switching device allows the second state to be retained” means that the switching device, based on the current operating state and / or the operating state curve assumes that the consumer is in the second state.
- the switching device comprises a switching element for applying an electrical voltage to the consumer.
- the switching element is provided in particular in the switching device. The positive result of the access authorization check is then a prerequisite for applying the electrical voltage for the consumer to the output by means of the switching element.
- the output is used for connection to a control line.
- a control voltage can be applied to the output. If the result of the access authorization check is positive, a control signal can be output via the output.
- the control voltage or the control signal then causes a switching element, e.g. B. a relay, outside the switching device, the electrical voltage to apply to the consumer or to change the energy consumption of the consumer, in particular to increase it.
- 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.
- 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.
- the consumer remains in the second state, there is no control signal.
- the voltage at the output is changed as a result of an access authorization, be it that the voltage for the consumer is applied directly to the output, be it that a control voltage is applied to the output or a control signal is sent via the output.
- the switching device changes the operating state of the output at the end of a delay period in order to cause the change to the second state.
- the change from the first state to the second state can take place at the end of the delay period after the switching device has gained knowledge of the positive result of the access authorization check.
- the delay period begins with the positive result of the access authorization check or a communication setup between the switching device and a mobile device. A change in the electrical status of the consumer is thus delayed.
- the length of 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, in particular to store it in the memory of the switching device.
- the switching device is designed to change the electrical state of a plurality of consumers, the switching device being able to selectively change the electrical state of the plurality of consumers.
- the electrical status of a first consumer is changed.
- the first consumer is transferred from the first state to the second state.
- the electrical state of a second remains Consumers unchanged despite the positive result of the access authorization check.
- the second consumer remains in the first state.
- an administrator can configure the loads for which the electrical status is to be changed.
- This configuration can be stored in the memory, in particular in a non-volatile memory, the switching device.
- the switching device can comprise several outputs. Logical electrical loads can be assigned to the outputs.
- the electrical state of at least one first consumer can be changed via a first output, but not the state of a second consumer.
- the electrical state of the second consumer can be changed via the second output, but not that of the first consumer.
- one output is used to supply power to a ventilation system and another output is used to supply power to a television.
- 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.
- 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 to be understood in such a way that the change in the operating state of the output serves to move the consumers that are actively connected or that can be effectively connected to the same output into the first or to transfer the second state.
- the switching device causes the change from the first state of the first consumer to the second state by means of the first output.
- a changed voltage is applied, in particular, to the first output.
- the second output does not cause any change.
- the voltage that is applied to the second output remains.
- the voltage applied to the second output can also be zero.
- the switching device can change the operating state of at least one output of the multiple outputs in order to cause the first state to change to the second state for the first consumer, while the switching device leaves the operating state of another output of the multiple outputs unchanged . This serves the purpose of leaving the state of the second consumer unchanged, in particular in the first state.
- the administrator can configure the output via which a change is initiated based on the positive result of the access authorization check and via which output no change is initiated. It can be configurable at which output a change in the operating state, in particular a voltage change, should take place on the basis of the positive result of the access authorization check and at which output no operating state change, in particular no voltage change, should take place.
- the access control system comprises several switching devices, in particular a first switching device and a second switching device. It can thus be provided that the access control system comprises an access control device, in particular precisely one access control device, and a plurality of switching devices.
- the multiple switching devices are provided to be arranged in the spatial area for which surveillance by the access control device is provided.
- each of the switching devices has its own electronic processor or controller.
- the switching devices can each include an electronic memory.

- the first switching device can change the operating state of at least one output in order to cause the first state to change to the second state for the first consumer, while the second switching device leaves the operating state of an output unchanged. It is thus also possible to selectively change the state of the loads by means of several switching devices. It may be that the outputs of a switching device of the plurality of switching devices always change the operating state at the same time. I. E. There is no selective behavior within a switching device. On the other hand, it is conceivable that the operating states of the own outputs are selectively changed in at least one of the plurality of switching devices.

- Each user has their own access attribute, e.g. B. an access code assigned.
- the outputs are thus assigned to the access attributes and / or their identifiers. This applies both to the case that a switching device is provided and also to the case that several switching devices are provided. It is thus conceivable that the outputs that are assigned to the access attributes are designed as outputs of the plurality of switching devices.
- the access control system in particular in the switching device, it can be stored for which access attribute or for which identifier associated with the access attribute at which output a voltage change is to take place. This means that the outputs can be assigned to the access attributes.
- the storage can take place in the memory, in particular in the memory of the switching device or the switching devices. The administrator can be authorized to make the assignment.
- the assignment of the outputs of the several switching devices to the access attributes takes place in such a way that the outputs of as few switching devices as possible are assigned to an access attribute.
- the switching devices themselves are assigned to the access attributes, so that if the access authorization check of an access attribute has been carried out with a positive result, only that switching device or those switching devices that are assigned to the access attribute, the operating states of their output or their outputs change.

- the delay period may also vary selectively for different consumers.
- the status change can be initiated via the outputs after different delay periods.
- a different delay period can be changed at the outputs at the end of different delay periods Voltage can be applied. This applies both to the case that a switching device is provided and also to the case that several switching devices are provided.
- a changed voltage is applied to a first output after a first delay period.

- the switching device changes the voltage at all those outputs to which at least one of the positively checked access attributes or the identifiers associated with the access attributes are assigned.

H. the electromechanical door fitting prevents the user from pulling back the locking element.

- 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 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 34 is designed as a socket.
- 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.
- 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.
- the access control device 2 as a result of the positive result of the access authorization check of the switching device 3, transmits an identifier of the mobile device 10 whose access attribute led to the positive result of the access authorization check.
- the identification is transmitted as a wireless transmitted message.
- 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.
- 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.
- 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, so that the mobile device 10 can start a communication with the switching device 3.
- the start of the wireless communication between the switching device 3 and the mobile device 10 is a further prerequisite for an electrical voltage to be applied to the loads 20.
- an electrical voltage is applied to the output 34 of the switching device 3.
- the operating state of the output 34 is thus changed.
- 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 the controller for the ventilation system 21 is operated, 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.
- the output 34 is part of circuits with the electrical loads 20.
- the mains voltage e.g. B. 220 V
- 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.
- a voltage is applied to output 34 so that current flows through the relay in order to switch an operating current relay.
- 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.
- 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.
- the switching device 3 If the mobile device 10 is within the communication range, the consumers 20 remain in the second state.
- the operating state, d. H. the voltage state at 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.
- either the mains voltage is taken from the output 34 or the control voltage is changed at the output 34.
- the control voltage 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.
- the control voltage In the case of a closed-circuit relay, the control voltage is switched on so that the open-circuit relay no longer has current flowing through it. 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 that the switching device 3 receives a signal from the mobile device and recognizes the signal as a communication signal is preferably adjustable.
- the switching device 3 can receive the signal strength value from the mobile device 10 or the access control device 2.
- the signal strength value can be determined by a calibration method.
- 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.
- 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.
- a single failure of communication is not enough to transfer the loads 20 to the first state. Rather, a predetermined period of time and / or a predetermined number of communication attempts must have taken place so that the switching device 3 recognizes the communication as terminated and initiates the transition to the first state.
- the ventilation system 21 should continue to run for a period of time after the communication has ended.
- 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.
- the switching device 3 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.
- the search for switches for consumers 20 are spared.
- 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.

- 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.
- the circuits of the loads 22, 23 can be switched via the first output 34, while the circuit of the ventilation system can be switched via the second output 35.

- the consumers 21, 22, 23 have been transferred from the first state to the second state.
- the voltage applied to the outputs 34, 35, 36 was changed.
- 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 and the corresponding access attribute are assigned to switch on the reading lamp 24.

- 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. 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. Communication between the mobile device 11 and the switching device 3 has started.

- various control signals can be applied to output 34.
- 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 an application of a voltage. Rather, a control unit of the ventilation system 21 is always live. 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.

- 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.
