Method for switching electrical consumers in one

building

The invention relates to a method for switching at least one electrical load in a building according to the preamble of the independent claim.

In building system technology, it is known to switch electrical consumers via switches. For this purpose, at least one power contact is switched from a building voltage network to the electrical consumer. For example, a lighting in the building is switched on or off or dimmed via a manual switch. Both the building voltage network and the manual switch are permanently installed in the surface or flush.

With the aim of increasing functionality, DE4425876A1 shows a socket with integrated network node and power supply of the network node. The network node communicates via a building voltage network in a bus system and switches according to commands from a higher-level control center, a relay of the socket. Connected to the socket electrical consumers are thus switched centrally. The building voltage network serves both to supply the electrical consumers with electricity and the communication between the network node and the center via the bus system.

With the goal of providing a simple communication standard which can be adapted to the most diverse conditions, according to http: // standards. ieee. org / getieee802 / download /802.15.4-2003.pdf the ZigBee near-field communications standard (IEEE 802.15.4) has been developed in which a command for switching the electrical load is transmitted via a separate wireless network from the building voltage network. Although only let Low data volumes of 20 to 250 Kb / s transmitted over short ranges of less than 300m, compared to the teaching of DE4425876A1, the near field communication has the advantage that the temporally and locally changing impedance behavior of the building voltage network can not lead to communication problems.

Object of the present invention is to develop the switching of electrical loads in a building.

This object is achieved by the invention according to the characterizing features of the independent claim.

The invention relates to a method for switching at least one electrical load in a building. The electrical load is powered by at least one electrical power supply with electrical power. At least one power contact from the electrical power supply to the electrical load is switched by at least one switch. The switch in turn is driven by at least one first network node. The first network node receives at least one control signal in at least one radio network. An identity of at least one user is detected by at least one second sensor and at least one second control signal is generated for a recognized identity of a user. The second control signal is transmitted from the second sensor via at least one second network node in the radio network.

This has the inventive advantage that an electrical consumer is user-specific switchable. For a recognized user, a second control signal can be generated and transmitted in a radio network to the electrical consumer. The process is quick and easy to install and requires little maintenance.

Advantageously, a detected identity of a user is checked. If for a detected identity of a user an access authorization of the user to a building area is present, at least a second control signal is generated. If there is no access authorization of the user to a building area for a detected identity of a user, at least one alarm signal is generated.

This has the advantage that only for users with access authorization, a second control signal is generated.

Advantageously, at least one lighting is switched by the first network node as the first electrical consumer or at least one door opener is switched as the second electrical consumer or at least one camera is connected as the third electrical consumer.

Advantageously, the second network node and the second sensor are supplied with energy independently from at least one second electrical power supply. Advantageously, the first network node and the switch of at least a first electrical power supply are supplied energy self-sufficient with electrical power. Advantageously, a second electrical load of at least one electrical power supply is self-sufficient energy supplied with electric power.

This has the advantage that the second network node and the second sensor or the first network node and the switch or the second electrical load can be placed on a hard to reach for a permanent power supply through a building voltage network body.

Advantageously, the second network node and the second sensor are supplied with electrical power by a second electrical power supply, which second electrical power supply is permanently supplied with electrical power by at least one building voltage network. Advantageously, the first network node and the switch of at least a first electrical power supply with supplied with electricity. The first electrical power supply and at least one electrical power supply of an electrical consumer are permanently supplied with electrical power by at least one building voltage network. Advantageously, control signals are routed or repeated in the radio network by the first network node.

This has the advantage that the first network node, which is permanently supplied with electrical power, performs network-specific additional functions such as routing, repeating, etc.

Advantageously, the first electrical power supply is connected directly to the building voltage network and is supplied with electrical power or the first electrical power supply is connected directly to the electrical power supply of an electrical load and is supplied with electrical power.

Advantageously, the opening or closing of at least one building door is detected by a first sensor and at least one first control signal is generated for a detected opening or closing of at least one building door. Advantageously, the first control signal indicates whether the building door is opened or closed by a side remote from at least one first electrical consumer and / or whether the building door is opened or closed by a side facing the first electrical consumer.

This has the advantage that the first sensor indicates in which

Direction of a user moves in the building, which simplifies the determination of the switching electrical consumers.

Advantageously, the first control signal is "ON" when a building door is opened or closed from a side facing away from the first electrical consumer. Advantageously, the first control signal is "OFF" or "DIMMING" when a building door is opened or closed by a side facing the first electrical load side. advantageously, the first electrical load is switched by the switch by the first control signal. If the first control signal is "OFF", the first electrical load is switched off immediately or with a freely adjustable delay. If the first control signal is "DIMMING", a brightness power of the first electrical load is reduced in at least one freely adjustable gradation and switched off after at least one freely adjustable delay. If a first control signal is "ON", the first electrical load is turned on immediately or with a freely adjustable delay.

This has the advantage that the first network node converts the first control signal offset in time, so that a space left by a user is not darkened abruptly but in brightness levels.

Advantageously, a first electrical load arranged in the shortest path distance to the first control signal generating first electrical load is switched first by the first control signal and a first electrical load arranged farthest away from the first sensor generating first sensor is switched last by a first control signal.

Advantageously, a control signal is transmitted via at least one second network node directly to the first network node. Advantageously, the control signal via the second

Network node transmitted to at least one third network node, and from the third network node, the transmitted control signal is transmitted to at least one control device.

This has the advantage that a control signal is converted either directly at a first network node, or by a

Control device is processed in advance. Especially when a single first or second electrical load to be switched, it is convenient to the control signal to transmit directly to the first network node of this first and second electrical load.

Advantageously, at least one first electrical load is determined for a transmitted first control signal. For the determined first electrical load, a network address of a first network node of a switch of the first electrical consumer is determined. The transmitted first control signal and the determined network address of the first network node are transmitted to the third network node. The transmitted first control signal is transmitted from the third network node to the determined network address of the first network node.

This has the advantage that the control device for a control signal can determine a plurality of first electrical consumers and associated first network nodes.

Advantageously, at least one target signal is generated for a transmitted first control signal, which target signal designates a building door. For a generated target signal, at least one first electrical load is determined. At least one first electrical consumer on the way from the first control signal generating first sensor to the designated by the target signal door is determined. For the determined first electrical load, a network address of a first network node of a switch of the first electrical consumer is determined. The transmitted first control signal and the determined network address of the first

Network nodes are transmitted to the third network node. The transmitted first control signal is transmitted from the third network node to the determined network address of the first network node.

This has the advantage that the control device generates a target signal for a first control signal and thus determines a path from the first sensor generating the first control signal to the building door in the building which is indicated by the target signal. Thus, an access door to the building can be permanently assigned to a first control signal of an access door to an apartment as a destination signal become. When leaving the apartment, all first electrical consumers are then automatically switched to the access door to the building.

Advantageously, at least one access authorization of a user to a building area is checked for a transmitted second control signal. If an access authorization of the user to a building area exists for a transmitted second control signal, at least one first electrical load in the building area is determined. At least a first control signal and a network address of a first network node of a switch of the first electrical consumer are determined for the determined first electrical consumer. The generated first control signal and the determined network address of the first network node are transmitted to the third network node. The first generated

Control signal is transmitted from the third network node to the determined network address of the first network node.

This has the particular advantage that only for users with access authorization, a first electrical load is switched in the access monitored building area.

If an access authorization of the user to a building area exists for a transmitted second control signal, advantageously at least one second electrical load in the building area is determined. For the determined second electrical load, a network address of a first network node of a switch of the second electrical consumer is determined. The transmitted second control signal and the determined network address of the first network node are transmitted to the third network node. The transmitted second control signal is transmitted from the third network node to the determined network address of the first network node.

Advantageously, the second electrical load is brought by the switch by the second control signal in the open position. This has the advantage that only for users with access authorization a second control signal is transmitted to the first network node of a second electrical consumer.

Advantageously, if there is no access authorization of the user to a building area for a transmitted second control signal, at least one alarm signal is generated.

Advantageously, at least one destination call signal is generated for a transmitted second control signal, which destination call signal designates a destination floor. The destination call signal is transmitted to at least one elevator control and at least one user is moved in at least one elevator car according to this destination call signal to the destination floor. At least one first electrical consumer on the destination floor is determined. For the determined first electrical load at least a first

Control signal and a network address of a first network node of a switch of the first electrical consumer determined. The generated first control signal and the determined network address of the first network node are transmitted to the third network node. The generated first control signal is transmitted from the third network node to the determined network address of the first network node.

This is advantageous since a destination call for an elevator installation is automatically generated by the second control signal. Thus, for a user for whom an identification sensor generates a second control signal on a start floor, a destination floor can be permanently predefined. For example, in the morning an identified user is automatically moved from the start floor in the parking garage to his office in the destination floor.

Advantageously, at least one target signal is generated for a transmitted second control signal. At least one building door is determined for a generated target signal. At least one path time from the second control signal generating second sensor to the designated by the target signal door is determined. It will check if before the end of the travel time, a first control signal of a first sensor of the building door designated by the target signal is transmitted. If no such first control signal is transmitted, at least one third electrical load is determined on the way from the second control signal generating second sensor to the designated by the target signal building door. At least a second control signal and a network address of a first network node of a switch of the third electrical consumer are determined for the determined third electrical consumer. The generated second control signal and the determined network address of the first network node are transmitted to the third network node. The generated second control signal is transmitted from the third network node to the determined network address of the first network node. The third electrical consumer is from the

Switch is switched to "ON" by the second control signal. At least one image of the path from the second sensor generating the second control signal to the building door designated by the target signal is recorded by the third electrical consumer. The captured image is transmitted from the third electrical load to the first network node. The transmitted image is transmitted from the first network node to the third network node. The transmitted image is transmitted from the third network node to the control device. The transmitted image is transmitted by the control device via at least one network to at least one remote center.

Advantageously, at least one previously generated reference image of a user is provided for the second control signal. The transmitted image is compared with the reference image. If the user is detected on the submitted image, it is determined whether the user is in a dangerous situation. If the user is in a dangerous situation, at least one alarm signal will be generated. Advantageously, the alarm signal and a location of the second sensor, which has generated the second control signal, transmitted to at least one remote center and / or building security. Advantageously, the alarm signal and a location of the third electrical

Consumer who has taken the image, transmitted to at least one remote center and / or building security. At least one security officer is assigned to the specified location of the second sensor or to the specified location of the third electrical load.

Advantageously, alternating electrical voltage of the building voltage network is converted by at least one rectifier of the first power supply into electrical mixing voltage. At least a portion of electrical mixing voltage is switched through by at least one transistor of the first power supply. At least one capacitor is electrically charged by the switched portion of electrical mixing voltage.

This has the advantage that electrical alternating voltage is switched equal without inductive load. A share of electrical

Mixed voltage passed through the output of the rectifier and a capacitor is electrically charged. The first electrical power supply supplies the electrical current charged in the capacitor. While conventional DC switch the same as the electrical mixed voltage using a current-compensating choke ferrite core, the present Gleichschaltung takes place without induction. As a result, in turn, the first electrical power supply is particularly small and also has low production costs.

Advantageously, at least one switching regulator is activated

Gate of the transistor controlled. Advantageously, the transistor is switched electrically conductively via the gate as soon as the electrical mixed voltage at the output of the rectifier falls below a freely definable first threshold value. Advantageously, the transistor is via the gate switched electrically non-conductive as soon as the electrical mixed voltage at the output of the rectifier exceeds the first threshold. Advantageously, the voltage applied to at least one first input of the switching regulator electrical mixing voltage is compared by at least one comparator with the first threshold.

This has the advantage that the first threshold prevents excessive electrical mixing voltage at the output of the rectifier from damaging components of the electrical circuit. The first threshold has a

Fuse function and switches at too high electrical mixing voltage, the transistor to electrically non-conductive.

Advantageously, a gate of the transistor is driven by at least one switching regulator. Advantageously, the transistor is switched to be electrically conductive via the gate, as soon as the passed-through portion of the electrical mixed voltage at the output of the rectifier falls below a freely definable first threshold value. Advantageously, the transistor is switched via the gate electrically non-conductive, as soon as the passed through portion of the electric mixed voltage at the output of the rectifier exceeds the first threshold. Advantageously, the applied at least one second input of the switching regulator passed through portion of electrical mixing voltage is compared by at least one comparator with the first threshold.

This has the advantage that the transistor is switched to be electrically conductive as a function of the load of the electrical power supply. If a large amount of electrical current is drawn from the charged capacitor, the switched-through proportion of mixed electrical voltage drops rapidly and the transistor is switched to be electrically conductive. If little or no electrical current is drawn, the transistor remains switched to non-conducting. The second threshold has a supply function and guarantees load-dependent charging of the capacitor. Advantageously, the switched-on transistor conducts electrical current during a threshold-defined time window. Advantageously, electrical current is passed through by the switched-on transistor, if the electrical mixing voltage is greater than or equal to an electrical DC voltage of the capacitor.

This has the further advantage that no electrical current can be returned to the rectifier. This also has the advantage that electrical DC voltage is generated with high energy efficiency, which is environmentally friendly.

Advantageously, the electrical DC voltage of the first electrical power supply in the range of 1.5V to 50V is freely set by at least one voltage divider.

Advantageously, the first network node and the first electrical power supply form a unit which is electrically contactable with the building voltage network for supplying electrical power. Advantageously, the first network node, the switch and the first electrical power supply form a unit which is electrically contactable with the building voltage network for supplying electrical power.

This has the advantage of simple and space-saving installation of the unit consisting of the first network node, the first electrical power supply and the switch.

Advantageously, a computer program product comprises at least one computer program means which is suitable for realizing the method for switching at least one electrical load by carrying out at least one method step if the computer program means has at least one processor in at least one processor

Network node or at least one control device or at least one remote center is loaded. Advantageously, a computer-readable data memory comprises such a computer program product.

Advantageously, a network node for use in the method for switching at least one electrical consumer has at least one computer-readable data memory and at least one processor, from which computer-readable data memory at least one computer program product means can be loaded into the processor and at least one method step can be executed. The network node has at least one antenna and transmits or receives at least one control signal in a radio network. At least one first electrical power supply supplies at least a first network node with electric current. The switch and / or the first network node and the first electrical power supply form a unit which is electrically contactable for supplying electrical power with at least one building voltage network.

Advantageously, a control device for use in the method for switching at least one electrical consumer has at least one computer-readable data memory and at least one processor, from which computer-readable data memory at least one computer program product means can be loaded into the processor and at least one method step can be executed.

According to FIGS. 8 and 9, a third electrical consumer 1 '' in the embodiment of a camera is switched by a first sensor 6 in the embodiment of a door sensor. The electrical consumer 1, 1 ', 1''is located in a building G. The building G comprises at least one room, the room may be mobile or stationary, the building G may also comprise several distributed spaces. Thus, the building G may very well be a mobile space such as an automobile, a caravan, a car, an elevator car, etc., or the building G may be a stationary space such as a residential building, an office building, a high-rise building, hospital, etc. or the building G can be several distributed rooms such as a building campus, an airport, a fairground, etc.

The building G comprises at least one building door 8. The

The building door 8 is an access door to an apartment in the building G and / or an access door to the building G. According to FIGS. 10 and 11, the building door 8 has at least one door leaf and a door frame. The door leaf has a door set with door handle 61 and door latch. The door frame has a strike plate.

The building G comprises at least one building voltage network 2.

The building voltage network 2 is standardized and has, for example, for three-phase current an electrical voltage of about 380VAC or 220VAC at a frequency of 50Hz and has an alternating voltage of between 90VAC and 270VAC at frequencies between 40Hz and 60Hz. The building voltage network 2 can of course also have a DC voltage of 24VDC or 42VDC. The building voltage network 2 is fixedly installed in the building G in the embodiment of electrical wiring in the surface or flush.

15 shows an exemplary embodiment of a building G having a plurality of horizontal floors S1, S2, S3 and an elevator installation A in a vertical elevator shaft S4. In the elevator shaft S4, at least one elevator car 12 is connected to at least one counterweight 14 via at least one suspension element 13. For moving the elevator car 12 and the counterweight 14, the suspension element 13 is supported by at least one elevator drive 13 in frictional motion. At least one user has at least one elevator door 10 access to the elevator car 12. On each floor Sl, S2, S3 forms an elevator door 10 the completion of the floors Sl, S2, S3 to the elevator shaft S4.

The call can be a landing call, a car call or a destination call. The terminal 9 transmits the call via at least one signal line to at least one

Elevator control 17. In a landing call, the elevator car 12 is moved to the start floor where the user has made a landing call, whereupon the user in the elevator car 12 makes a car call to a destination floor.

The energetic activation takes place automatically as soon as the mobile call input device 10 is within the range of the electromagnetic field of a few centimeters to one meter. Once the mobile call input device 10 is energetically activated, the processor reads out an identification code stored in the data memory, which is sent to the recognition device 92 via the coil.

According to FIG. 10, the engine and locking bolt are installed in the strike plate of the door frame. According to FIG. 11, the engine and lock bolt are installed in the door trim of the door leaf. In the closed position of the lock bolt is extended and closes the building door 8. In the open position, the lock bolt is moved back and releases the building door 8. By pressing lightly against the

Building door 8 locks it out of the strike plate of the door frame and opens. The motor is powered by an electrical power supply 51 'with electrical power. A switch 3 opens or closes a power contact from the building voltage network 2 to the power supply 51 'of the door opener. For example, the motor is operated with a DC electrical voltage of 42VDC.

In FIGS. 2 to 9, this communication is represented by curved triple-circle segments. The radio network 40 allows bi-directional communication according to known and proven network protocols such as Transmission Control Protocol / Internet Protocol (TCP / IP) or ZigBee Protocol.

A network node 4, 4 ', 4''has at least one processor and at least one computer-readable data memory and at least one antenna. At least one computer program means is loadable from the computer readable data memory into the processor. The computer program means controls the communication of the network node 4, 4 ', 4''via the antenna in the radio network 40.

At the output of the rectifier 5.1 is a mixed electrical voltage with an AC voltage component and a DC component. The ratio of AC voltage component and DC component is referred to as ripple. The electrical mixing voltage pulsates with this ripple. The output of the rectifier 5.1 is connected via an electrical conductor 5.13 to an input of at least one transistor 5.3.

The transistor 5.3 is switched via the gate 5.23 electrically conductive as soon as the electrical mixing voltage at the first input of the switching regulator 5.2 below a freely definable first threshold or as soon as the passed to the second input of the switching regulator 5.2 proportion of electrical mixing voltage falls below a freely definable second threshold. Accordingly, the transistor 5.3 is switched electrically nonconducting via the gate 5.23, as soon as the electrical mixed voltage at the first input of the switching regulator 5.2 exceeds the first threshold or as soon as the passed to the second input of the switching regulator 5.2 proportion of electrical mixing voltage exceeds the second threshold. The voltage applied to the first input of the switching regulator 5.2 electrical mixing voltage or applied to the second input of the switching regulator 5.2 transmitted proportion of electrical mixed voltage is are each compared by a comparator with the first and second threshold.
