Description

The invention relates to an electrical / electronic device for the energy supply of a building generating solar current, which is optimized in its own consumption and / or in autarkyity, in particular a socket, having a central piece surrounded by a design frame and a base part fixed to a supporting ring, wherein a voltage supply unit can be fixed to the base part, which on the one hand comes into operative connection with the base part in a contacting manner and which on the other hand is provided for the electrical connection of at least one electrical functional assembly.The invention further relates to a network comprising at least two such electrical / electronic devices for building installation technology.Electrical / electronic devices, for example sockets, switches or buttons, are regularly connected to an energy supply system, usually: to various circuits in a building.EP 1962391 B1 discloses an electrical / electronic device having a lighting means as an integrated emergency or orientation lighting means, which according to a development is also suitable for causing a lighting means to be switched on only below an adjustable brightness threshold on the basis of a brightness sensor and an evaluation unit connected thereto. This measure extends the service life of the battery and thus the burning time of the lighting means in the event of a power failure. In this respect, electrical / electronic devices with brightness sensors, in particular as insulation sensors, are known.However, the disadvantage of the previously known electrical / electronic devices with brightness sensors is that they do not allow the energy supply of a building generating solar current to be optimized with regard to self-consumption and / or self-sufficientness, for example when the aim is to supply electric vehicles, electric bikes or other consumers with electrical energy which is generated for the most part or completely itself.Battery management systems or load management systems are likewise known for supplying energy to a building generating solar power, but these systems are complicated to install and are to be controlled only by expert users.Proceeding from this discussed prior art, the object of the invention is to create an electrical / electronic device, for example a socket, which optimizes the energy supply of a building generating solar current in a cost-effective and simple manner with regard to self-consumption and / or self-sufficientness.This object is achieved by an electrical / electronic device which has a sensor for detecting the brightness, wherein a signal is generated with respect to the detected brightness, which signal is conducted to a relay connected to the electrical / electronic device for switching a circuit of the building installation technique, provided that the brightness lies above an adjustable brightness threshold corresponding to a solar power.The core idea of the invention is that the electrical / electronic device according to the invention is capable of detecting the brightness in a building or in the environment of a building. Based on the brightness detected, an energy supply of a building generating solar current optimized for its own consumption or autarkyness is then achieved by generating a signal with respect to the brightness detected, which signal is conducted to a relay connected to the electrical / electronic device for switching a circuit of building installation technology. The energy supply is only switched on when the brightness lies above an adjustable brightness threshold corresponding to a solar power. This ensures that a high level of intrinsic consumption or autarchia of the current generated by a photovoltaic system is achieved. If, for example, an electric vehicle with a socket with a power of 2.3 kW is to be charged in a self-consumption or auto-sufficient manner, the charging process is only started by a relay connected to the electrical / electronic device for switching a circuit of building installation technology if the device arranged, for example, on the building outer wall or inner wall detects via the brightness sensor that the brightness is above an adjustable brightness threshold corresponding to a solar power. Solar power is understood to mean a power generated by a photovoltaic installation. Expediently, the brightness threshold from which the energy supply of the circuit of the building installation technique is enabled is determined in a simple manner by comparing the power required for the energy supply of a load, here: 2.3 kW, with the power generated by the photovoltaic installation corresponding to the current brightness (for example by matching with the inverter at a specific brightness). By selecting the brightness threshold, it can be achieved that the supply of a load connected to a circuit of the building installation technique is self-consumption-optimized by avoiding that the power generated by the photovoltaic installation is not fed into the energy supply network, but rather is used itself. This allows the user of the electrical / electronic device according to the invention for energy supply optimized for intrinsic consumption to set the measure of intrinsic consumption in a simple manner, for example by entering the brightness threshold via a terminal which communicates with the electrical / electronic device or the relay for switching a circuit.Self-consumption-optimized means that grid feeding is avoided by utilizing excess energy to be expected generated by the photovoltaic system by switching on corresponding consumers inside the building.A high degree of autarchia means that excess energy generated exclusively or predominantly by the photovoltaic system is used to supply specific loads.The electrical / electronic device according to the invention for building system technology has a central piece surrounded by a design frame and a base part fixed to a supporting ring, wherein a voltage supply unit can be fixed to the base part. The voltage supply unit, on the one hand, comes into operative connection with the base part in a contacting manner and, on the other hand, is provided for the electrical connection of at least one electrical functional assembly. Such a functional module can be, for example, a lighting device, a radio transmitter or one or more USB connections which are integrated into the central board in a flush manner with the design frame.For the connection of the at least one electrical functional assembly, the voltage supply unit preferably has at least one connection socket, into which connection socket a plug connector is inserted in a contacting manner.In addition, such a device preferably has a printed circuit board adjoining the central piece and having an electrical / electronic functional component and which can be inserted into the central piece. Preferably, the sensor for detecting the brightness is arranged on this printed circuit board.In a particularly preferred embodiment according to the invention, the voltage supply unit for connecting the at least one electrical functional assembly has at least one connection socket, into which connection socket a plug connector is inserted in a contacting manner. A flex circuit board section which can be spread apart from the plane of the circuit board and which has the plug connector, extends from the circuit board for mounting the electrical / electronic device. This flex circuit board section is joined to a receptacle of a receptacle section, extending in the direction of the voltage supply unit, of a housing part connected to the circuit board for the electrical connection of the plug connector of the circuit board to the connection socket of the voltage supply unit. It is particularly advantageous in this embodiment that the flex circuit board section provides additional installation space without impairing the installation depth and the installation effort. In this respect, this embodiment of the invention is a particularly space-saving embodiment which is simple to produce and which can also accommodate further electronic functionalities in terms of space.In a further embodiment according to the invention, the relay is arranged in the electrical / electronic device, in particular in the base part. This makes it possible to ensure in a simple manner that the electrical / electronic device is only carrying voltage if this is desired, in particular if the required brightness threshold is not reached.According to a further embodiment according to the invention, the relay is arranged in an actuator connected to the electrical / electronic device. As a result, the user can achieve the desired effects, for example, in a simple manner and by way of retrofitting.In a further embodiment according to the invention, the electrical / electronic device is connected to a relay in the series-mounted device in the sub-distribution. This allows entire circuits, for example socket circuits within a room, to be disconnected, so that a plurality of consumers can be supplied with energy simultaneously and not supplied at the same time.According to a particularly preferred embodiment of the invention, the electrical / electronic device is connected to a mobile terminal for transmitting the switching states of the relay and also detected brightnesses. This makes it possible to visualize the brightnesses and the phases in which an energy supply of a connected load has taken place. Particularly preferably, the electrical / electronic device likewise has a power detection device which allows the power consumption of the load to be displayed in time and thus to provide information about the energy for supplying the load.According to a particularly preferred embodiment of the invention, the electrical / electronic device is a socket and has a hinged cover which has a brightness sensor and which hinged cover is connected to the voltage supply unit of the socket via a flex printed circuit board or another flexible contact.The use of a hinged lid allows use outdoors while complying with the required standards with regard to splash protection. The brightness can be determined by the brightness sensor in the hinged cover and transferred to the socket part of the socket through the flex printed circuit board.In a preferred development of this development, the hinged cover has its own printed circuit board which partially or completely replaces the optional printed circuit board which can be inserted into the central board. This makes it possible to save installation space in an installation box by virtue of a part of the electronics being displaced outwards (but protected by the hinged lid lying in front of it). The electrical connection to the base part is ensured via the flex printed circuit board.In an alternative embodiment with respect to the hinged lid solution, the sensor is arranged in the design frame, which design frame is connected to the voltage supply unit via an interface.According to a particularly preferred embodiment of the invention, the device is connected to further actuators and / or sensors in a building automation system, wherein the detected brightness signal is provided for activating the actuators and / or sensors.The invention further relates to a network comprising at least two such electrical / electronic devices according to the invention. The particular feature of this network is that the electrical / electronic devices are connected to one another and the sensors of the electrical / electronic devices are aligned in different cardinal directions. This allows the relay to be switched for switching a circuit of building installation technology depending on the sky direction-specific brightness detected by the sensors, in particular evaluated by an evaluation unit. This ensures that the brightness can be determined in different cardinal directions, which information can be incorporated into the optimum energy supply that is optimized for its own consumption and / or autonomous. If, for example, a photovoltaic system is directed to west and the sun is east, a single brightness sensor would indeed give a brightness value, but this is only inaccurately usable by the photovoltaic system with regard to the solar power generated. In this respect, a sky direction-specific brightness determination allows consideration of the alignment of the photovoltaic installation, for example by setting a brightness threshold in the sky direction in which the photovoltaic installation points lower than is the case with a brightness threshold which is detected by an electrical / electronic device according to the invention which detects the brightness in a direction which points away from the photovoltaic installation. Weighting of different brightness values can also be carried out, so that an image of the spatial brightness distribution that is as good as possible is produced. On the basis of the individual detected brightnesses and / or the total brightness, the energy supply of a load can be compared as a function of one or more brightness thresholds that can be specified by the user. Likewise, such a spatial brightness distribution makes it possible, on the basis of the comparison of the brightnesses in different sky directions, to determine whether this is rather diffuse or direct solar radiation, which can likewise be incorporated into the definition of the brightness threshold(s).According to a particularly preferred, since it is convenient to handle, development of this network according to the invention, the latter furthermore comprises a terminal device, in particular a mobile terminal device, by means of which a brightness threshold specific to the direction of the sky, in particular per sensor, can be defined, in which the relay is switched for supplying power to a load.The invention is described below with reference to the attached figures on the basis of various exemplary embodiments. The following are shown: FIG. 1 : shows a perspective exploded view of an embodiment of the electrical / electronic device according to the invention, FIG. 2 : a further perspective exploded view of an embodiment of the electrical / electronic device according to the invention, FIG. 3 : shows a schematic illustration of a hinged cover which has the brightness sensor and which, according to the invention, interacts with a socket, with the result that use of the socket in the open air is made possible, FIG. 4 shows a schematic illustration of a design frame having the brightness sensor, FIG. 5 : shows a schematic illustration of a network of three electrical / electronic devices according to the invention in the external region, the brightness sensors of which point in different celestial directions, while the charging process is active on account of sufficient brightness at the east side of the building, FIG. 6 : shows a schematic illustration of a network of three electrical / electronic devices according to the invention in the external region, the brightness sensors of which point in different celestial directions, while the charging process is inactive on account of lack of brightness on the east side of the building, FIG. 7 : shows a schematic illustration of an electrical / electronic device according to the invention in the interior region, the brightness sensor of which is arranged in the vicinity of a window, while the charging process is active on account of sufficient brightness on the east side of the building, and FIG. 8 : shows a schematic illustration of an electrical / electronic device according to the invention in the interior region, the brightness sensor of which is arranged in the vicinity of a window, while the charging process is inactive on account of lack of brightness on the east side of the building.In the various figures, identical parts are always provided with the same reference numerals and are therefore generally also designated or mentioned only once in each case.The electrical / electronic device 1 according to the invention, which is shown in perspective in FIG. 1, comprises, in addition to a design frame 2, an attachment A and an insert E. The attachment A comprises a central piece 3, a printed circuit board L which has a plurality of electrical / electronic functional components (in particular a radio module and / or an LED and / or an evaluation electronics) and can preferably be inserted into the central piece 3, a housing part 5 which is connected, for example by means of snap-fit engagement M, to the associated recess 4 of the printed circuit board L, and an optional mechanical contact protection 6, which additionally protects against improper operation, for example by children.As FIG. 2 shows in a schematic exploded illustration, a flex circuit board section F which can be spread apart from the plane of the circuit board L and which has a plug connector 7 and can be deflected out of the plane of the circuit board L for mounting the electrical / electronic device 1 preferably starts from the circuit board L. This flex circuit board section F is joined to a receptacle 8 of a receptacle section 9 of the housing part 5 connected to the circuit board L, which receptacle extends in the direction of the voltage supply unit S. The insert E comprises a support ring 10, a base part 11 and a voltage supply unit S. In this case, the voltage supply unit S is designed to be connected to a voltage supply of a building installation technique and to convert the supplied voltage into a required supply voltage, for example 3.5V.As can be seen in FIGS. 1 and 2 on the basis of a particularly preferred embodiment, the sensor X is arranged on the printed circuit board L in order to record the brightness. The position is only exemplary; other arrangements of the sensor X, for example in the design frame 2 or in any hinged lid K, can also be provided, which design frame 2 is connected to the voltage supply unit S via an interface.FIG. 3 shows a schematic illustration of a hinged cover K which has the brightness sensor and which, according to the invention, interacts with a socket (not illustrated), with the result that use of the socket in the open air is made possible-in particular the required protection classes are fulfilled without a sensor X arranged, for example, in the central piece 3 being covered by the hinged cover K. In an analogous manner, the sensor X, as shown in FIG. 4, can also be arranged in the design frame 2 for the same reasons, while the electrical / electronic device 1 has a hinged lid K.FIG. 5 shows a schematic illustration of a network of three electrical / electronic devices 1 according to the invention in the external area, wherein the brightness sensors point in different celestial directions, while the charging process is active on account of sufficient brightness at the east side of the building. Because the sensors X of the electrical / electronic devices 1 are oriented in different sky directions and the relay R is switched for switching a circuit of the building installation technique as a function of the sky direction-specific brightness detected by the sensors X, in particular evaluated by an evaluation unit, the energy supply of a load V connected to the socket connected to the relay R, in this case an E-bike, is possible in a particularly self-consumption-optimized and / or self-sufficiently optimized manner: the switching of the relay R can take place taking into account the sky direction-specific brightness detected by the sensors X. This allows the orientation of the photovoltaic system PV on the building to also enter into the definition of a sky direction-specific brightness threshold. If, for example, a low brightness is measured on the west side, but the sun is eastern, the brightness information specific to the direction of the sky can be used to switch the relay R to supply power to a load V.As illustrated in FIG. 6, in the reverse case that the photovoltaic system PV points to a side from which the brightness is particularly low, while the sun falls on a brightness sensor of an electrical / electronic device 1, which sensor X faces the sun (here: the west side), the charging of the e-bike is switched to passive.FIG. 7 shows a schematic illustration of a single electrical / electronic device 1 according to the invention in the interior region, the sensor X of which is arranged in the vicinity of a window, while the charging process is active on account of sufficient brightness on the east side of the building. Here, the brightness threshold is intentionally not determined in a direction-specific manner but only worked with a single sensor X. As soon as the brightness threshold is undershot, the charging of the load V via the relay R for switching a circuit of the building installation technique is stopped (see FIG. 8 ). It is understood that a plurality of electrical / electronic devices 1 can also be interconnected in the interior region to form a network analogous to the network shown in FIG. 6.The invention is described with reference to exemplary embodiments. Without departing from the scope of the applicable claims, a person skilled in the art would find numerous further possibilities for implementing them without this having to be explained in detail within the scope of these explanations.List of reference characters1 Electrical / electronic device 2 Design frame 3 Central piece 4 Recess 5 Housing part 6 Contact protection 7 Plug connector 8 Receptacle 9 Receptacle section 10 Support ring 11 Base part 12 Sub-distribution A Attachment E Insert F Flex circuit board section K Hinged lid L Circuit board M Snap-fit latch PV Photovoltaic system R Relay S Voltage supply unit V Consumer X Sensor Y Window cutoutReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
