Description

The invention relates to an (encapsulated) control switching module for a building control device and such a building control device.

Today, the desire for automation and control of building parts or electrical devices within a building has increased steadily. So there is not only the desire, for example, to regulate the indoor climate in a building automatically to a certain temperature value, but also the lighting or blinds or roller shutters should take on a certain brightness value or a predetermined position under computer control.

The DE 11 2011 103 818 B4 describes a device and a method for controlling electrical consumers. To stabilize the power grid, electrical consumers are switched on when there is a lot of energy in the power grid and switched off when there is little energy. The mains voltage is measured for this. If the mains voltage exceeds a predetermined threshold value, the consumer is switched on and otherwise switched off. Corresponding switching commands can also be supplied to the device from an external device. The switching operations carried out can in turn be transferred to the external device.

The DE 10 2007 041 180 A1 concerns retrofittable electronic switch modules that are used for preventive burglary protection and with which the lights and switches permanently installed in the rooms are switched on to simulate presence at certain times.

From the DE 41 36 673 C2 a light switch for the selective control of a lamp or lamp group is known. A codable device is used to generate a characteristic number of consecutive vibrations for the lamp or lamp group to be switched and to transmit it to the coded switching module of the lamp or lamp group, which switches on the lamp or lamp group on the basis of the number of consecutive vibrations.

The DE 10 2012 217 963 A1 describes an interactive socket that includes an acoustic sensor device that can detect acoustic signals. The interactive socket has a signal generating device which, based on the acoustic signals detected by the acoustic sensor device, generates a transmission signal which can be transmitted externally by means of the communication device. With this design of the socket, a speech processing component can be integrated into a socket. Through the communication device of the socket, complex parts of the speech processing can be implemented in a cloud service, whereby both the quality of the speech interaction can be increased and the hardware costs can be reduced.

From the DE 10 2015 009 361 A1 a device for the automated detection of an electrical device connected to a socket insert is known. The device comprises a socket insert arranged in the socket for receiving a plug of the electrical device, an electrical connection of the socket to an electrical supply network, for example a 220 V AC voltage network, a switching element via which the electrical device connected to the socket insert switches on or off. can be switched off and a communication module integrated in the socket that interacts with a remote or central data processing device, wirelessly or via a building bus by means of a further connection. The plug of the electrical device to be inserted into the socket insert is equipped with a radio label on which data relating to the device type of the electrical device to be connected to the intelligent socket are stored. The intelligent socket is provided with a reader, which enables communication between the radio tag and the reader when the plug is inserted in such a way that the reader detects a signal with modulated data relating to the device type of the electrical device inserted into the socket from its radio tag and makes one contact remote data processing device transmits.

The DE 20 2005 010 430 U1 relates to an energy transmission line which is equipped with a protective circuit. The energy transmission line comprises a protective circuit, the protective circuit opening the power line or interrupting or opening a closed circuit or temporarily interrupting the provision of electrical energy to the load when an overcurrent and / or overvoltage operating state occurs on the DC voltage in order to prevent overloading and prevent damage to the load.

Switching modules are known from the data sheets of the company Eltako GmbH "Current impulse switching relay with current measurement FSR61VA-10A" and "Current impulse switching relay FSR61LN-230V" in order to connect a load to the mains and to separate it from the mains. These switching modules have a communication device and can send wireless telegrams, which means several Switching modules can be connected to a scene. Configuration is carried out using rotary switches on the switching module itself.

From the DE 10 2011 102 038 A1 a home automation control system and a corresponding method are known. It is explained that gestures of a person in a room can be detected using detection means such as cameras, infrared sensors, etc. These are evaluated and an actuator is activated accordingly. For example, a floor lamp can be switched on or off in this way.

Such a home automation control system is advantageous with regard to the new type of control, but it is disadvantageous that it can only be installed in new buildings at reasonable costs. A large number of separate actuators with additional lines must be provided in order to enable both control by gestures and control by conventional means.

It is therefore the object of the present invention to provide a control switching module for a building control device and a corresponding building control device which, compared to the prior art, can easily be used in existing electrical installations, on the one hand to continue to ensure the previous manual control of the electrical devices can and to enable automated control of these electrical devices.

The object is achieved by the control switching module according to independent claim 1 and by the building control device according to claim 26. Further developments of the control switching module according to the invention are found in claims 2 to 25, whereas claims 27 to 33 describe advantages of the building control device according to the invention.

The control switch module according to the invention, which is particularly suitable for use in surface and flush-mounted boxes, but can also be used in cable ducts, lamps and lights as well as switches, sockets and dimmers, comprises a supply conductor connection, at least one power conductor Connection, a neutral conductor connection and at least one control conductor connection. It also has a switching device, a power supply device and a control and communication device. The switching device is arranged between the supply conductor connection and the at least one power conductor connection and the energy supply device is designed to provide a supply voltage at least for the control and communication device and preferably also for the switching device. The control and communication device is designed to detect an electrical signal in the form of a voltage or a current at the at least one control conductor connection. In particular, it is detected whether a voltage or a current is present or not (digital value), but the level of the voltage level or current level can also be detected (analog value). The latter also includes a profile of the electrical signal, for example a phase control or a phase control or a pulse width modulation. The voltage can be a DC voltage or an AC voltage. The same applies to electricity. The control and communication device is designed, in dependence on the assigned configuration information and a change (level, frequency, course, etc.) of the detected electrical signal at the at least one control conductor connection, to control the switching device in such a way that it controls the at least one power conductor connection interconnects with the supply conductor connection or interrupts an existing interconnection and transmits a module message wirelessly, this containing switching information which causes another control switching module, which receives this module information wirelessly, to interconnect its power conductor connection with its supply conductor Establish connection or interrupt such an interconnection.

It is particularly advantageous that at least one control conductor connection is provided and that the interconnection is established or changed or interrupted as a function of the electrical signal or as a function of a change in the electrical signal at the at least one control conductor connection. This makes it possible for the control switch module to be inserted very easily into existing electrical wiring. For example, only the connection between a light switch and the lamp has to be disconnected, the light switch being connected to the control conductor connection and the lamp being connected to the power conductor connection in order to additionally create an automation option. When the switch is actuated, a voltage is present at the control conductor connection, whereupon an electrical connection is established between the supply conductor connection and the power conductor connection, as a result of which the lamp begins to light up. Conversely, the electrical connection can of course also be disconnected. A module message can be sent wirelessly, which contains switching information, so that another control switching module can also carry out a switching process can. In this case, the lighting of a room can easily be changed afterwards, because additional lamps can simply be “switched on” by their control switching modules receiving the module message, evaluating it and controlling the switching device accordingly. “Configuration information” is understood to mean in particular a mode of operation of the control switching module. This includes actions that the control switching module executes when a specific change in the electrical signal is detected at the control conductor connection. For example, a (certain type of) interconnection and / or certain switching information to be sent can be stored in a module message in the event that a certain change in the electrical signal at the control conductor connection is detected. The wording “assignable” means that this configuration information is both programmable by the manufacturer and can be changed wirelessly by a user (in operation).

The term “interconnection” means on the one hand the establishment of a digital electrical connection and on the other hand the establishment of an analog electrical connection.

In the “digital” electrical connection, the at least one power conductor connection is always electrically conductively connected to the supply conductor connection by the switching device for the duration of the interconnection. A signal at the supply conductor connection remains unchanged at the power conductor connection. In the case of the “analog” electrical connection, the at least one power conductor connection is connected in a pulsed, electrically conductive manner to the supply conductor connection through the switching device for the duration of the interconnection. The pulsed, electrically conductive connection takes place in the context of a phase control or a phase control or a pulse width modulation or a frequency converter control. The wording “pulsed” is understood to mean that the supply conductor connection is connected in an electrically conductive manner to the at least one power conductor connection at very short time intervals and is disconnected from it again. The signal at the power conductor connection is therefore different from the signal at the supply conductor connection. It is also possible for the voltage and / or the frequency at the at least one power conductor connection to be adjustable and to be different from the voltage and / or the frequency at the supply conductor connection. As a result, for example, the effective value of the voltage or of the current at the at least one power conductor connection can be reduced, as a result of which less power is transmitted and, for example, an illumination device can be dimmed.

Establishing an analog electrical connection is useful, for example, when an analog encoder is connected to at least one control conductor connection in order to implement a dimmer control. In this case, the control and communication unit controls the switching device in such a way that it sets a corresponding analog state at the corresponding power conductor connection.

Furthermore, a measuring device is also provided in order to be able to detect a voltage value or a sequence of voltage values at the various connections and / or a current value or a sequence of current values at the power conductor connection or the control conductor connection. From the sequence of voltage values and / or current values, the control and communication device can calculate a measured value, which is in particular a consolidated voltage value (effective value, mean value, maximum value, minimum value) or a consolidated current value (effective value, average value, maximum value). Minimum value). The consolidation takes place in particular by calculating the result of a corresponding functional mapping of a current and / or voltage sequence to a measured value, for example the functional mapping of a "voltage sequence" to the exemplary measured value "voltage rms value" is the root of the integral of the squared voltage curve the time divided by the duration of the sequence. The measured value can also contain an energy value or a power factor. This measurement information can then be packaged in a module message and sent wirelessly by the control and communication device. The control switching module thus allows the construction of an energy management system for the individual electrical consumers connected to the power conductor connection.

1. (i) die Schalteinrichtung derart angesteuert wird, dass diese die Zusammenschaltung des zumindest einen Leistungsleiter-Anschlusses und des Versorgungsleiter-Anschlusses unterbricht und so den zumindest einen Leistungsleiter-Anschluss von dem Versorgungsleiter-Anschluss elektrisch trennt; und/oder
2. (ii) die Schalteinrichtung derart angesteuert wird, dass diese den Versorgungsleiter-Anschluss und/oder den Steuerleiter-Anschluss mit dem Neutralleiter-Anschluss niederohmig und/oder kurz schaltet, um dadurch eine Überspannungsableitung zu erreichen.

The measured value can then be used for a variety of purposes. For example, a protective function can be implemented for electronic devices that are connected to the power conductor connection. In this way, the measured value can be compared with a corresponding threshold value, and when this threshold value is reached and / or exceeded:

1. (i) the switching device is controlled such that it interrupts the interconnection of the at least one power conductor connection and the supply conductor connection and thus electrically isolates the at least one power conductor connection from the supply conductor connection; and or
2. (ii) the switching device is controlled in such a way that it Connection and / or the control conductor connection with the neutral conductor connection switches low-resistance and / or briefly in order to achieve an overvoltage dissipation.

In another exemplary embodiment, the control switching module can basically also be designed to pack the measured value into measurement information and to send it wirelessly as a module message. In principle, it is also conceivable that such control switching module can specifically request measured values. In this way, a module message containing protocol information can be sent to the control switching module. Depending on this protocol information, the control switching module selects the corresponding measured value, packs it into measurement information and sends this measurement information wirelessly in a module message.

In a preferred embodiment, the control switching module can be operated in different operating modes. The appropriate operating mode can be selected depending on the application. The purposes depend heavily on whether a switch or a button is connected to the control conductor connection and what kind of electrical consumer is to be controlled. In this way, a single consumer can be connected to the power conductor connection, which is supposed to be controlled by one switch or button. However, it can also be the case that the consumer is to be controlled by several pushbuttons, or that the power with which the consumer is to be operated is to be set by means of a corresponding signal at the control conductor connection.

Therefore, four operating modes of the control switching module are described below. The operating mode in which the control switching module is operated depends on the assigned configuration information. This configuration information can be predefined by the manufacturer and / or changed by the user during operation.

A first operating mode is selected when a switch is connected to the control conductor connection, which is to take over a main switching function. For example, this could be a main switch implemented as a bistable toggle switch. This switch is connected to a consumer. In a hotel room, such a main switch could, for example, be a plug-in device for a key card. In this case, a response is made to a level on at least one control conductor connection. For this purpose, the measured value is compared to determine whether it reaches or exceeds a first threshold value or whether it reaches or falls below a second threshold value. The switching device is controlled in such a way that it connects the at least one power conductor connection to the supply conductor connection when the measured value at the at least one control conductor connection exceeds a predetermined first threshold value. Additionally or alternatively, the switching device is controlled such that it interrupts the interconnection of the at least one power conductor connection from the supply conductor connection when the measured value at the at least one control conductor connection falls below a predetermined second threshold value. Both threshold values can be chosen to be identical or different from one another, the latter case representing a kind of hysteresis and avoiding switching over too frequently in limit ranges. At the same time, this “MASTER” control switching module can also send a corresponding module message that contains such switching information so that another control switching module that receives this module message can control its switching device in accordance with the switching information. Alternatively, this additional control switching module (so to speak as "SLAVE") can ignore any switching information received both at the control conductor connection and wirelessly if the last switching information sent by the "MASTER" control switching module was a "lock signal" or the normal one Allow or resume switching functionality in response to signal changes at the control conductor connection or wirelessly arriving switching commands if the last switching information sent by the "MASTER" control switching module was a "release signal".

1. (i) eine bestehende Zusammenschaltung des zumindest einen Leistungsleiter-Anschlusses mit dem Versorgungsleiter-Anschluss unterbricht; oder
2. (ii) den zumindest einen Leistungsleiter-Anschluss bei einer fehlenden Zusammenschaltung mit dem Versorgungsleiter-Anschluss zusammenschaltet.

Jedes Mal, wenn der Taster betätigt wird, findet daher genau ein Wechsel des Schaltzustands statt. Ergänzend oder alternativ dazu kann auch noch eine Modulnachricht generiert und drahtlos ausgesendet werden, die eine entsprechende Schaltinformation beinhaltet. Diese Schaltinformation bewirkt bei dem empfangenden Steuer-Schaltmodul, dass dieses einen Wechsel seines Schaltzustands vornimmt. Dieser Betriebsmodus wird auch dann eingesetzt, wenn eine „Treppenhausbeleuchtung“ mit mehreren Tastern realisiert werden soll. In diesem Fall gibt es zumindest ein Steuer-Schaltmodul, welches mit einer Lampe (= elektrischer Verbraucher) verbunden ist. Dieses empfängt drahtlose Modulnachrichten von anderen Steuer-Schaltmodulen, die mit den Tastern verbunden sind. Das Betätigen eines dieser Taster führt immer dazu, dass sich der Betriebszustand der Lampe ändert. Ist sie ausgeschalten, dann wird sie eingeschalten und umgekehrt.In contrast, in the second operating mode, only a flank on the at least one control conductor connection is reacted to. For example, it is preferably only possible to “trigger” on a rising or (in an alternative scenario) only on a falling edge. This operating mode is selected when a button is to be connected to the control conductor connection. In the second operating mode, the control and communication device is designed to control the switching device in such a way that, in the event that the measured value at the at least one control conductor connection exceeds or falls below a first threshold value (in the alternative scenario):

1. (i) interrupts an existing interconnection of the at least one power conductor connection with the supply conductor connection; or
2. (ii) interconnects the at least one power conductor connection when there is no interconnection with the supply conductor connection.

Every time the button is pressed, the switching state changes exactly. In addition or as an alternative to this, a module message can also be generated and transmitted wirelessly, which contains corresponding switching information. This switching information causes the receiving control switching module to change its switching state. This operating mode is also used when "staircase lighting" with several buttons is to be implemented. In this case there is at least one control switching module which is connected to a lamp (= electrical consumer). This receives wireless module messages from other control switch modules that are connected to the buttons. Pressing one of these buttons always causes the operating state of the lamp to change. If it is switched off, then it is switched on and vice versa.

1. i) eine bestehende Zusammenschaltung des zumindest einen Leistungsleiter-Anschlusses mit dem Versorgungsleiter-Anschluss unterbricht; oder
2. ii) den zumindest einen Leistungsleiter-Anschluss bei einer fehlenden Zusammenschaltung mit dem Versorgungsleiter-Anschluss zusammenschaltet.

A third operating mode, on the other hand, serves to either wirelessly control an existing installation in which a consumer (for example a lamp) is switched on or off by means of a bistable switch via a central control device or a mobile terminal device. The third operating mode also serves, for example, to implement "staircase lighting" with several switches. In this mode, every change in the position of each switch should result in a switched-on consumer being switched off and a switched-off consumer being switched on. With several switches and therefore several control switch modules, depending on the position of the switches, a falling level at a control conductor connection of a control switch module can result in the consumer not being switched off but switched on. In the third operating mode, the control and communication device is therefore designed to compare the measured value at the at least one control conductor connection with a first threshold value. The control and communication device is also designed both for the case that the measured value at the at least one control conductor connection exceeds the first threshold value and for the case that the measured value at the at least one control conductor connection exceeds the threshold value or a second one The switching device falls below the threshold value in such a way that it:

1. i) interrupts an existing interconnection of the at least one power conductor connection with the supply conductor connection; or
2. ii) interconnects the at least one power conductor connection when there is no interconnection with the supply conductor connection.

In addition or as an alternative to this, a module message can also be generated and transmitted wirelessly, which contains corresponding switching information. This switching information causes the receiving control switching module to change its switching state. In this case there is at least one control switching module which is connected to a consumer. This receives wireless module messages from other control switch modules that are connected to the switches. Changing the switching status of one of these switches always means that the status of the consumer changes. If it is switched off, it is switched on and vice versa.

As can be seen, the third operating mode can also be used to implement a staircase switch with several bistable switches. It can also be seen that a staircase circuit with several pushbuttons and switches in mixed form and / or several lamps can be implemented, the control switch modules connected to a switch working in the second operating mode and the control switch modules connected to the switch in the third operating mode. All wirelessly addressed control switching modules that can switch a lamp on or off can work in the second or third operating mode.

In the first three operating modes, the corresponding power conductor connection is only digitally electrically connected to the supply conductor connection. This means that the two connections are permanently connected to one another for the entire time of their interconnection.

1. a) die Schalteinrichtung derart ansteuert, dass diese eine derartige analoge elektrische Verbindung zwischen dem zumindest einen Leistungsleiter-Anschluss und dem Versorgungsleiter-Anschluss herstellt, sodass im allgemeinen Fall das Ergebnis einer zweiten funktionalen Abbildung einer Spannungssequenz am Leistungsleiter-Anschluss oder Stromsequenz durch die Schalteinrichtung, insbesondere ein Effektivwert der Spannung am Leistungsleiter-Anschluss, oder des Stromes durch die Schalteinrichtung dem Messwert entspricht; und/oder
2. b) eine Modulnachricht drahtlos aussendet, die eine Schaltinformation beinhaltet, die ein weiteres Steuer-Schaltmodul dazu veranlasst, eine derartige analoge elektrische Verbindung zwischen dem zumindest einen Leistungsleiter-Anschluss und dem Versorgungsleiter-Anschluss herzustellen, sodass eine Entsprechung wie unter a) beschrieben erreicht wird.

In a fourth operating mode, an analog electrical connection takes place between the at least one power conductor connection and the supply conductor connection. This means that the at least one power conductor connection is connected in a pulsed, electrically conductive manner to the supply conductor connection. Such a connection is used in particular to reduce the power that can be transmitted to an electrical consumer. In particular, the effective value of the voltage and / or the current at the at least one power conductor connection can be reduced as desired by means of a corresponding control (phase control or phase control or pulse width modulation or frequency converter control). In the fourth operating mode, this control takes place depending on the signal at the control conductor connection. This signal is analyzed and the switching device) is controlled such that the signal at the power conductor connection has the same shape. In general, the measured value is in particular the result of a first functional mapping of a voltage or current sequence, in particular an effective value of a voltage or a current and it applies that the control and communication device is designed to:

1. a) controls the switching device in such a way that it establishes such an analog electrical connection between the at least one power conductor connection and the supply conductor connection, so that in general the result of a second functional mapping of a voltage sequence at the power conductor connection or current sequence through the switching device, In particular, an effective value of the voltage at the power conductor connection or the current through the switching device corresponds to the measured value; and or
2. b) wirelessly sends out a module message which contains switching information which causes a further control switching module to establish such an analog electrical connection between the at least one power conductor connection and the supply conductor connection, so that a correspondence as described under a) is achieved .

1. a) die Sequenz von Spannungswerten an dem zumindest einen Steuerleiter-Anschluss; oder
2. b) die Sequenz von Stromwerten an dem zumindest einen Steuerleiter-Anschluss; oder
3. c) den Messwert an dem zumindest einen Steuerleiter-Anschluss

dahingehend zu untersuchen, ob das elektrische Signal an dem zumindest einen Steuerleiter-Anschluss ein gepulst elektrisches Signal, in Form einer Phasenanschnittssteuerung oder einer Phasenabschnittssteuerung oder einer Pulsweitenmodulation oder einer Frequenzrichter-Steuerung ist. Die Steuer- und Kommunikationseinrichtung ist dann weiterhin dazu ausgebildet, für den Fall, dass ein gepulst elektrisches Signal am zumindest einen Steuerleiter-Anschluss anliegt:

1. a) die Schalteinrichtung derart anzusteuern, dass diese den zumindest einen Leistungsleiter-Anschluss mit dem Versorgungsleiter-Anschluss entsprechend der Form des untersuchten elektrischen Signals gepulst elektrisch leitend verbindet, bzw.
2. b) eine Modulnachricht zu erzeugen und drahtlos auszusenden, die eine Schaltinformation beinhaltet, die ein weiteres Steuer-Schaltmodul dazu veranlasst seine Schalteinrichtung derart anzusteuern, dass diese Schalteinrichtung seinen zumindest einen Leistungsleiter-Anschluss mit seinem Versorgungsleiter-Anschluss entsprechend der Form des untersuchten elektrischen Signals gepulst elektrisch leitend verbindet.

In particular, the control and communication device in the fourth operating mode can also be designed to

1. a) the sequence of voltage values at the at least one control conductor connection; or
2. b) the sequence of current values at the at least one control conductor connection; or
3. c) the measured value at the at least one control conductor connection

to investigate whether the electrical signal at the at least one control conductor connection is a pulsed electrical signal, in the form of a phase control or a phase control or a pulse width modulation or a frequency converter control. The control and communication device is then further designed, in the event that a pulsed electrical signal is present at the at least one control conductor connection:

1. a) to control the switching device in such a way that it connects the at least one power conductor connection to the supply conductor connection in a pulsed, electrically conductive manner in accordance with the shape of the electrical signal being examined, or
2. b) to generate and wirelessly send out a module message which contains switching information which causes a further control switching module to control its switching device in such a way that this switching device pulses its at least one power conductor connection with its supply conductor connection in accordance with the shape of the electrical signal being examined connects electrically conductive.

In principle, it is possible for the control switching module to receive a module message with at least one configuration information item. The control switching module can receive this module message from a central control device and / or from a further control switching module and / or from a mobile terminal. The assignable configuration information is used for configuration, that is to say for updating the control switching module. In this way, they can specify which electrical parameters are to be measured or how the switching device is to react to different electrical signals on at least one control conductor connection. In this way, it can also be determined in which of the four operating modes the control and communication device is operated.

The supply conductor connection can preferably be connected to the public power grid or another energy source. The same preferably also applies to the at least one control conductor connection, which can be connected to the power supply via an on / off switch (e.g. switch, button, dimmer, etc.). The neutral conductor connection, on the other hand, can be connected to the ground conductor of the public power grid or to a ground conductor of the other energy source. This enables a very simple integration of the control switch module into existing electrical wiring or installations.

In a further exemplary embodiment, the control and communication device is designed to control the switching device in dependence on a received module message, which contains switching information, in such a way that it connects the at least one or respective power conductor connection with the supply conductor connection or an existing one Interconnection interrupts.

In principle, the control switching module can also be configured such that the control and communication device sends a module message that it receives wirelessly from another control switching module and / or from a central control device and / or from a mobile terminal to another control device. Switching module and / or wirelessly transmitted to a central control device and / or to a mobile terminal. In this case, the control switching module would work as a repeater.

The control switching module particularly preferably comprises a (one-piece) housing arrangement which comprises at least the switching device, the energy supply device and / or the control and Surrounds communication device. The supply conductor connection, the at least one power conductor connection, the neutral conductor connection and the at least one control conductor connection are accessible from outside the housing arrangement and can be connected to an electrical installer. The housing arrangement preferably consists of a dielectric material, in particular a casting compound, such as epoxy resin or a plastic compound. The housing arrangement can also comprise a closable plastic housing which contains the electronic part. Appropriate protection against accidental contact, i.e. galvanic isolation, is achieved. A module message, which contains, for example, switching information, can be transmitted to the control switching module wirelessly, that is to say without contact, so that no live parts have to protrude outward from the housing arrangement of the control switching module. Optionally, this housing arrangement can also include the integration of an externally visible light-emitting diode or signal lamp, by means of which the control and communication device can display a current internal state of the control switching module by means of coded flashing sequences, colors and / or brightness values. In principle, an acoustic device could also be provided, which is designed to audibly output a tone sequence and / or a certain pitch and / or a certain volume to the outside (to the outside of the housing arrangement), which encodes an internal state of the control switching module.

The building control device according to the invention comprises at least one such control switching module. The supply conductor connection is connected to the supply conductor of the public power grid. The neutral conductor connection is connected to the ground conductor of the public power grid. At least one electrical consumer is provided, which is electrically connected to the at least one power conductor connection of the control switching module. The at least one electrical consumer is either connected to the neutral conductor connection of the control switching module or directly to the ground conductor of the public electricity network. The control and communication device of the at least one control switching module is designed to control the switching device as a function of a change in the electrical signal at the at least one control conductor connection in such a way that it connects the at least one power conductor connection to the supply conductor connection and thus the puts at least one electrical consumer into operation or disconnects an existing interconnection and puts the electrical consumer out of operation.

It is particularly advantageous if at least one switch-on / switch-off device in the form of a switch, button, touch panel, motion detector or dimmer is provided, with a first connection of this switch-on / switch-off device to the supply conductor of the public electricity network or to an energy source ( eg battery in the case of a touch panel) is electrically connected, and a second connection of the at least one on / off switching device is electrically connected to the at least one control conductor connection of the at least one control switching module. When the at least one on / off switching device is actuated, the first connection is electrically conductively connected to the second connection and a voltage signal is present at the at least one control conductor connection. In this case, the control switching module connects the electrical consumer to the supply conductor of the public power grid.

It is also particularly advantageous if a central control device and / or a mobile terminal is provided. These are designed to wirelessly transmit module messages to the at least one control switching module, these module messages containing switching information and / or configuration information and / or protocol information. The central control device and / or the mobile terminal is further or additionally designed to receive module messages from the at least one control switching module, the module messages containing measurement information and / or status information. The central control device is also designed to transmit or receive module messages to a user's mobile terminal (e.g. smartphone). In this way, a user can configure the individual control switching modules or receive measured values from them in a particularly simple manner via the central control device. The mobile terminal could of course also communicate directly with the individual control switching modules.

This central control device preferably also includes a microphone and is designed to be able to receive and evaluate voice commands. These voice commands can then be translated into module messages and transmitted to the at least one control switching module, where the content of these module messages is evaluated.

A plurality of control switching modules are preferably used, which are designed to forward module messages to one another. These are especially designed to form a MESH network, a scatter network, a daisy-cain network or a tree network.

The wireless connection, that is to say the radio connection, is advantageously a WLAN connection (e.g. WIFI, Zigbee, etc.) or a WPAN connection (Wireless Personal Area Network, e.g. Bluetooth® connection or Bluetooth®-compatible connection such as Bluetooth Low Energy). The Bluetooth® connection can also include a Bluetooth® MESH connection. The WLAN connection is one according to IEEE 802.11 * (e.g. a, b, ...). The Bluetooth® connection is preferably one according to IEEE 802.15. * (E.g. 1,2, ...). With these connections, device-specific data are preferably still transmitted when the module messages are transmitted, so that the control and communication device of the respective control switching module or the central control device receive the received module messages to the respective control switching modules and thus to the corresponding electrical consumers which are connected to the control Switch modules are connected, can assign. Such a unique device and / or network number is usually achieved directly by using the appropriate protocol (WLAN or Bluetooth®).

Advantageously, the central control device is also designed to request a module message from one or all control switching modules at regular intervals, which message contains measurement information, for example. The regular time intervals can be in the second or minute interval (several minutes such as 1, 2, 4, 6, 8 minutes or several seconds such as 1, 4, 6, 10, 20, 30, 40 seconds).

In order to obtain a control switching module that is as compact as possible, the switching device, the energy supply device, the control and communication device and optionally also a measuring device are designed as a system-in-package. This means that either all or part of the corresponding devices are arranged in a common (chip) housing.

The 1A to 1C show different embodiments of the control switching module according to the invention 1 that in a building control facility 2 can be used. The control switch module 1 can also be used as an encapsulated control switch module 1 or as a flush-mounted or surface-mounted control switching module 1 be designated. The control switch module 1 could also act as a control actuator 1 be designated. According to the 1A and 1C are preferably four connections 3a . 3b . 3c and 3d intended. This includes a supply conductor connection (L) 3a , a neutral conductor connection (N) 3b , at least one power conductor connection (Q) 3c and at least one control conductor connection (C) 3d ,

The supply conductor connection 3a is preferably with a supply manager 4a of the public power grid 4 connectable (e.g. 3 ). The neutral conductor connection 3b is against a ground conductor 4b of the public power grid 4 connectable.

The control switch module 1 also includes a switching device 5 , an energy supply facility 6 and a control and communication device 7 , A measuring device is also optional 8th intended. The switching device 5 is between the supply conductor connection 3a and the at least one power conductor connection 3c arranged. The switching device 5 is designed to connect the supply conductor 3a with the at least one power conductor connection 3c interconnect or separate such interconnection. The switching device 5 consists preferably of a solid state relay, or of an electronic circuit that simulates one. There is preferably an energy flow from the supply conductor connection 3a to the at least one power conductor connection 3c , Optionally, a backflow should also be possible. At the supply conductor connection 3a there is preferably an AC voltage such as 230 volts or 110 volts. However, a DC voltage could also be present. The switching device 5 can therefore comprise a triac circuit, a thyristor circuit, a MOSFET circuit or an IGBT circuit and / or a mechanically operating relay.

The energy supply facility 6 is designed to provide a supply voltage at least for the control and communication device 7 and optionally also for the switching device 5 to generate and provide them. In 1A is the energy supply facility 6 shown as a voltage divider with two impedances, which on the one hand with the supply conductor connection 3a and on the other hand with the neutral conductor connection 3b connected is. The energy supply device preferably comprises 6 still at least one rectifier circuit, and further preferably still a linear regulator, to a constant DC voltage for the control and communication device 7 to be able to generate. The energy supply facility 6 is therefore designed to connect to the supply conductor 3a applied voltage to generate the supply voltage. The energy supply facility 6 could also include a step-down converter instead of a voltage divider, whereby a rectifier would have to be connected upstream.

Basically, the energy supply device 6 still have at least one energy storage device such as a battery, a rechargeable battery or a capacitor, from which the supply voltage for the control and communication device can be derived 7 refer to.

The control and communication device 7 is designed to use an electrical signal (voltage or current) on the at least one control conductor connection 3d the switching device 5 head for. The control and communication device 7 can therefore detect whether such an electrical signal on at least one control conductor connection 3d is present or not. As will be explained later, the electrical signal can be, for example, the level of the mains voltage on the supply conductor 4a of the public power grid 4 exhibit.

The control and communication device 7 is therefore in particular able to provide a signal value and / or an effective value of the electrical signal at the control conductor connection 3d capture. In particular, a voltage value or a current value or an effective value of the voltage value or an effective value of the current value is measured.

The control and communication device 7 can then depend on this voltage signal on at least one control conductor connection 3d the switching device 5 control such that it connects the at least one power conductor 3c with the supply conductor connection 3a interconnects or interrupts an existing interconnection. As described at the beginning, the interconnection can be a “digital” electrical connection or an “analog” electrical connection. Roughly speaking, the "digital" electrical connection is the signal from the supply conductor connection 3a unchanged also on at least one power conductor connection 3c on, whereas this signal in the "analog" electrical connection is still changed in amplitude and / or frequency, for example.

The control and communication device is supplementary or alternative 7 also able to send a module message 10 (see e.g. 7 ) generate and send wirelessly, the module message 10 a switching information 10a contains.

For this purpose, the control and communication device includes 7 an antenna arrangement, not shown.

A wireless connection is understood in particular to be a WLAN connection (IEEE 802.11 *) or a Bluetooth ^® connection (IEEE 802.15. *) Or a ZigBee ^® connection (IEEE 802.15.4).

The control and communication device 7 can also receive a firmware package wirelessly and update its own firmware with the received firmware package.

A control switch module 1 can both module messages 10 received as well as module messages 10 to ship. The module news 10 have multiple functions and can contain different information. For example, a module message 10 a switching information 10a include. Such switching information 10a may include a switching command specifying that and how the switching device 5 the supply conductor connection 3a with the at least one power conductor connection 3c interconnect or that an interconnection should be interrupted, or that the state of the interconnection should be changed, i.e. an existing interconnection should be interrupted or a missing interconnection should be established. Receives a control switch module 1 , in particular the control and communication device 7 of the control switching module 1 , such a module message 10 that have a switching information 10a then the control and communication device 7 trained to switch this information 10a evaluate. According to the switching information 10a becomes the switching device 5 through the control and communication device 7 controlled.

A module message 10 can also include a header, that is, a device ID, which is unique for each control switching module, whereby the sender of the respective module message 10 , i.e. the corresponding control switching module 1 or a central control device 20th (please refer 8th ) can be identified.

1. a) einen konsolidierten Spannungswert, beispielsweise Effektivwert, Mittelwert, Maximalwert, Minimalwert, und/oder
2. b) einen konsolidierten Stromwert, beispielsweise Effektivwert, Mittelwert, Maximalwert, Minimalwert, und/oder
3. c) einen konsolidierten Leistungswert, beispielsweise Schein-, Blind-, Wirk-Leistungswert, der von dem Versorgungsleiter-Anschluss 3a an den zumindest einen Leistungsleiter-Anschluss 3c übertragen wird; und/oder
4. d) einen Energiewert der elektrischen Energie, die von dem Versorgungsleiter-Anschluss 3a an den zumindest einen Leistungsleiter-Anschluss 3c in einem bestimmten Zeitintervall übertragen wurde; und/oder
5. e) einen Leistungsfaktorwert.

The module message 10 can also provide measurement information 10b include that in interaction with the measuring device 8th can be used. The measuring device 8th includes several measuring connections 8a . 8b . 8c (please refer 1C ) and is designed to provide a voltage value or a sequence of voltage values of a voltage applied to the supply conductor connection 3a and / or on the at least one power conductor connection 3c and / or on the at least one control conductor connection 3d is present, opposite the neutral conductor connection 3b to eat. The measuring device can measure this voltage value or this sequence of voltage values 8th to the control and communication device 7 transfer. The measuring device is supplementary or alternative 8th also configured to a current value or a sequence of current values of a current that is connected via the at least one power conductor connection 3c , for example between the supply conductor connection 3a and the at least one power conductor connection 3c , flows and / or via the control conductor connection 3d flows to measure and this current value or this sequence of current values to the control and communication device 7 transferred to. The current value is preferably obtained by using a shunt resistor or a Hall sensor, the shunt resistor or Hall sensor being between the supply conductor connection, for example 3a and the at least one power conductor connection 3c is arranged. The control and communication device 7 is designed to calculate a measured value from the sequence of voltage values and / or from the sequence of current values. This measured value is:

1. a) a consolidated voltage value, for example effective value, mean value, maximum value, minimum value, and / or
2. b) a consolidated current value, for example effective value, mean value, maximum value, minimum value, and / or
3. c) a consolidated power value, for example apparent, reactive, active power value, from the supply conductor connection 3a to the at least one power conductor connection 3c is transmitted; and or
4. d) an energy value of electrical energy generated by the supply conductor connector 3a to the at least one power conductor connection 3c was transmitted in a certain time interval; and or
5. e) a power factor value.

The consolidation is preferably the result of a functional mapping of the voltage sequence, the current sequence, or the combination of voltage and current sequence into one measured value. For example, the rms voltage value is the result of forming a root from the integral of the squared voltage values over time divided by the duration of the voltage sequence. The control and communication device 7 is then designed to provide measurement information 10b the module message 10 add and send them out. The measurement information 10b includes the measured value described above. The consolidated power value indicates electrical power from the supply conductor connector 3a in the direction of the at least one power conductor connection 3c or vice versa. The energy value indicates the electrical energy from the supply conductor connection over a certain time interval (eg 1 hour, 1 day, etc.) 3a in the direction of the at least one power conductor connection 3c or transmitted back. By means of such measurement information 10b can put an energy management system around the control switching module 1 be built around.

The module message 10 can also still configuration information 10c include. The control and communication device 7 of a control switch module 1 can this configuration information 10c in the module message 10 evaluate and their previous configuration information 10c update accordingly. Depending on the assigned configuration information 10c measures the measuring device, for example 8th only certain measured values or the control and communication device 7 only reacts to certain forms of the electrical signal (level or edge) on at least one control conductor connection 3d or only evaluates switching information 10a out by a particular control switch module 1 come. The configuration information 10c can also serve the corresponding control switching module 1 set such that this is only switching information 10a generated and as a module message 10 sent and the own switching device 5 does not control or that only switching information 10a in a module message 10 received and depending on this the own switching device 5 is controlled, whereas electrical signals at its own at least one control conductor connection 3d to be disregarded. However, this fact is explained in more detail in the course of the next figures.

1B shows an exemplary structure of the control and communication device 7 , At the control and communication facility 7 it is preferably a computer chip. The control and communication device 7 preferably comprises several I / O connections, which are designated GPA, GPB, in order to be able to connect additional devices. The control and communication device 7 also includes, for example, bus systems such as I ² C, SPI, CAN. The control and communication device 7 preferably comprises power supply connections (POW) to additional devices, such as the switching device 5 and / or the measuring device 8th to be able to supply with electrical energy. The control and communication device 7 preferably also includes a voltage input VTP via which energy from the energy supply device 6 can be supplied. A programming interface LNK allows the programming of the control and communication device 7 ,

Basically, the control and communication device 7 also trained to send a module message 10 to encrypt before it is sent wirelessly, or to decrypt a received and encrypted module message.

An antenna arrangement can be placed directly in the housing of the control and communication device 7 be integrated. The antenna arrangement can also be designed externally, with one. Line an electrical connection with a corresponding output, not shown, of the control and communication device 7 will be produced. The control and communication device preferably uses 7 a Bluetooth® connection to receive module messages 10 to be able to exchange. An ultrasound connection would also be conceivable.

2A shows a housing arrangement 11 of the control switching module according to the invention 1 , In this case it is shown that the switching device 5 , the energy supply device 6 , the control and communication device 7 and the measuring device 8th are designed as a system-in-package and are arranged in a common (chip) housing. This (chip) package is called the package arrangement 11 designated. The individual facilities 5 . 6 . 7 . 8th are preferred on a common circuit board 12 arranged. In principle, however, not all of the facilities 5 to 8th on the common circuit board 12 be arranged. For example, the switching device 5 even outside the circuit board 12 be arranged. The use of the circuit board 12 is not mandatory either.

2 B shows a housing arrangement 11 that the switching device 5 , the energy supply device 6 , the control and communication device 7 and possibly the measuring device 8th surrounds.

2C shows a simplified circuit diagram of the control switching module 1 how this in spatial representation in 2 B is shown.

The housing arrangement 11 includes cable connection facilities 12a . 12b . 12c . 12d to the supply conductor connection 3a , the neutral conductor connection 3b , the at least one power conductor connection 3c and the at least one control conductor connection 3d with an electrical installation outside the housing arrangement 11 to be able to connect. The cable connection devices 12a to 12d are designed as screw and / or clamp connections, with a connection cable in an opening of the respective cable connection device 12a to 12d can be inserted and wherein a clamping effect can be achieved, for example, by screwing or spring-loaded pressing. The individual electrical contacts are preferably not from outside the housing arrangement 11 accessible by touch, so that there is electrical isolation between the housing arrangement 11 and the electrical components. The cable connection devices 12a to 12d are comparable in terms of their mechanical fixation and electrical contacting of the connection cables, preferably with luster terminals or box terminals or plug-in terminals, as can be found in switches and sockets. Alternatively, the control switch module 1 Instead of screw or plug-in terminals contain short cable pieces that are inside the housing arrangement 11 with the electrical circuit (switching device 5 , Energy supply facility 6 , Control and communication device 7 , Measuring device 8th ) are soldered and can be connected outside to a luster terminal, socket terminals, or switches or sockets.

There are preferably two supply conductor connections 3a and two neutral conductor connections 3b , which further preferably on different sides of the housing arrangement 11 are arranged. They could all be on the same page. According to 2C are each connected to each other in an electrically conductive manner. This ensures that the control switching module is installed 1 in an existing electrical installation, especially in a flush-mounted or surface-mounted box, can be easily achieved. The supply manager 4a of the public power grid 4 is separated and the control switching module interposed, whereby the supply conductor 4a of the public power grid 4 is continuously connected again. The same applies to the ground conductor 4b of the public power grid 4 , This too can be easily separated with the two neutral conductor connections 3b . 12b , on two different, preferably opposite sides of the housing arrangement 11 are arranged to be connected.

The housing arrangement 11 consists of a dielectric or comprises a dielectric, in particular a dielectric casting compound, which in turn consists for example of an epoxy resin or a plastic compound, or a closable plastic housing which contains the electronics.

The control switch module 1 has in 2 B in plan view a rectangular or square shape. The control switch module 1 should be together with its housing arrangement 11 but have a size that ensures that this can be inserted into a flush-mounted box. In plan view, the shape could therefore also be circular (diameter preferably less than 10 cm, 8 cm, 6 cm, 5 cm, 4cm, 3cm, 2cm, 1cm), the individual cable connection devices 12a to 12d are preferably arranged evenly spaced from one another, but are also arranged on a single side, or alternatively on only two or three sides.

In 2 B is another broken cable connection device 12e shown. Their structure corresponds to the previous cable connection devices 12a to 12d , This additional cable connection device 12e can be connected to a protective conductor of an electrical installation.

The control and communication device 7 is then designed in the event that, for example, between the supply conductor connection 3a and the power conductor connection 3c a current flows that exceeds a predetermined threshold value, an overcurrent fault at the protective conductor connection, that is to say via the corresponding cable connection device 12e output to the electrical installation. For example, the measured value is compared to a corresponding threshold value. The control and communication device can handle this overcurrent fault, which is preferably a current 7 preferably generate yourself or connect to the output via a corresponding additional switching device. Corresponding circuit breakers in the electrical installation recognize a current on the protective conductor and disconnect the corresponding network segment. The output of such an overcurrent error can be useful if the current (measured value) exceeds a threshold value that is higher than the current that the switching device can switch as much as possible. In this case there would otherwise be no way to connect the supply conductor 3a from the power conductor connection 3c to separate. In this case the module message could 10 corresponding status information 10d be added, which is transmitted wirelessly.

The control and communication device 7 Could also be designed to compare the measured value with a corresponding threshold value and the switching device when this threshold value is reached and / or exceeded 5 to be controlled in such a way that it connects the supply conductor 3a and / or the control conductor connection 3d with the neutral conductor connection 3b switches low-resistance and / or briefly in order to achieve an overvoltage dissipation.

In the 3A to 3C other uses of the control switch module 1 explained. 3A shows that the control switching module 1 both a digital electrical connection and an analog electrical connection between the at least one power conductor connection 3c and the supply conductor connection 3a can manufacture.

3B explains that the control switching module 1 a change (eg level) at the at least one control conductor connection 3d can determine, and with such a detected change a) a change in the interconnection at the power conductor connection 3c by appropriate control of the switching device 5 and b) the control and communication device 7 a module message 10 generates the corresponding switching information 10a includes and sends them wirelessly.

In 3C is shown that the control switching module 1 alternatively to a change in the control wire connection 3d also on the arrival of a module message 10 with corresponding switching information 10a can react. If the receiving control switch module 1 due to the in the switching information 10a containing address is addressed, the switching device 5 prompted to carry out a corresponding interconnection, or to disconnect an existing interconnection. Otherwise, the control switching module 1 work like a repeater and the module message 10 forward. The control switch module 1 then receives module messages 10 and forwards them accordingly. Basically all module messages can 10 to get redirected. However, filtering can also take place. So the control switch module 1 prefers such module messages 10 do not forward again that it has already sent out. It is also possible that only module messages 10 from a particular control switch module 1 and / or to a specific control switching module 1 to get redirected. The module news 10 can also be changed. The steering- Switching module 1 out 3C in this case evaluates no electrical signals at the at least one control conductor connection 3d and uses its own switching device 5 neither.

In the 3B and 3C is still assignable configuration information 10c shown the operation of the control switching module 1 describes. Depending on this assignable configuration information 10c can the control switching module 1 can be operated in different operating modes. The assignable configuration information. 10c can be wirelessly connected to the control switching module 1 be transmitted. It is also possible that the assignable configuration information 10c during the manufacture of the control switch module 1 is assigned, for example by hard-wired hardware, by storage information in a read-only memory, by storage information in a FLASH memory. In some of these cases, the assignable configuration information would be 10c in the operation of the control switching module 1 unchangeable.

The 4B and 4D show a first exemplary application of the control switching module according to the invention 1 which is in a building control facility 2 is inserted. In 4A a conventional electrical installation is shown in which the electrical consumer 15 via an on / off switch 16 , which is a switch, can be switched on or off (also corresponds to 4C ). That is, when the on / off device is actuated 16 The voltage of the supply conductor is permanently in the form of a switch 4a of the public power grid 4 on the electrical consumer 15 on. The on / off switch 16 includes a first connection 16a and a second connector 16b , The first connection 16a is with the supply manager 4a of the public power grid 4 electrically connected, the second connector 16b with the electrical consumer 15 is electrically connected. When the on / off switch is actuated 16 is also the second connection 16b with the supply manager 4a of the public power grid 4 connected.

In 4B explains how such an existing electrical device with the control switching module according to the invention 1 can be retrofitted. The control switch module 1 can be easily inserted into an installation box (flush-mounted or surface-mounted box) of the existing electrical installation, be it an installation box for the on / off switch or an installation box for distribution. Instead of the installation box, it can also be installed in a cable duct or directly in a lamp. The supply conductor connection 3a of the at least one control switching module 1 is with the supply manager 4a of the public power grid 4 connected. The neutral conductor connection 3b of the at least one control switching module 1 is against the ground conductor 4b of the public power grid 4 connected. The electrical consumer 15 is not directly connected to the second connection this time 16b the on / off switch 16 connected, but with the at least one power conductor connection 3c of the at least one control switching module 1 , On the other hand is the second connection 16b the on / off switch 16 with the at least one control conductor connection 3d of the at least one control switching module 1 electrically connected, whereas the first connector 16a continue directly with the supply manager 4a of the public power grid 4 or indirectly via the supply conductor connection 3a of the control switching module 1 is electrically connected.

The control and communication device 7 of the at least one control switching module 1 is designed to be a function of the voltage signal at the at least one control conductor connection 3d , the switching device 5 to be controlled such that it connects the at least one power conductor 3c with the supply conductor connection 3a interconnects and the electrical consumer 15 so puts into operation or disconnects an existing interconnection and the electrical consumer 15 thereby decommissioning.

So that the control switch module 1 is working properly, it must match the type of on / off device connected 16 configured correctly. The control and communication device 7 is therefore designed to be a module message 10 from another control switch module 1a to 1c to receive wirelessly, this module message 10 at least one configuration information 10c contains. This module message 10 can, as later with regard to 8th is explained in more detail, also by a central control device 20th or a mobile device 21 be received wirelessly. About this configuration information 10c can the control switching module 1 and in particular the control and communication device 7 be operated in a first or third operating mode (when a switch is connected) or in a second operating mode (when push buttons are connected). The control and communication device is preferably 7 trained to use the measuring device 8th a measured value of the electrical signal, for example in the form of a consolidated voltage value or current value) of the electrical signal at the at least one control conductor connection 3d to eat.

The first operating mode, also called level control, is selected when a switch is connected to the control conductor 3d is connected. In this case, a level on at least one control wire connection 3d responding. For this purpose, the first measured value is compared as to whether it reaches or exceeds a first threshold value or whether it reaches or falls below a second threshold value. The switching device 5 is controlled in such a way that it connects the at least one power conductor 3c with the supply conductor connection 3a interconnects when the measured value at the at least one control conductor connection 3d exceeds a predetermined first threshold. The switching device is supplementary or alternative 5 controlled in such a way that the interconnection of the at least one power conductor connection 3c from the supply conductor connection 3a interrupts when the measured value at the at least one control conductor connection 3d falls below a predetermined second threshold value. At the same time, a corresponding module message can also be sent 10 be sent that such switching information 10a contains, so another control switching module 1b . 1c which this module message 10 receives its switching device 5 according to the switching information 10a can control.

Alternatively or in addition, this module message can 10 however, as a switching function also a permit or a ban for a receiving control switching module 1 included to fulfill its switching functionality defined by configuration. The control switch module 1 is designed in this case only in response to a change in the electrical signal at the control conductor connection 3d and / or as a function of a wirelessly received module message 10 that have a switching information 10a includes the switching device 5 to be controlled such that it connects the at least one power conductor 3c with the supply conductor connection 3a interconnects when the control switching module 1 previously a module message 10 has received a switching information 10a contains, which includes an enable signal. This switching information 10a can be from another control switching module 1 , a central control device 20th and / or a mobile device 21 come. The control switching module is an alternative or supplement 1 designed to be independent of a change in the electrical signal at the control conductor connection 3d and / or regardless of a wirelessly received module message 10 that have a switching information 10a includes the switching device 5 to be controlled such that they interconnect the power conductor connection 3c with the supply conductor connection 3a interrupts or stops when the control switching module 1 previously a module message 10 has received a switching information 10a contains a lock signal.

The measured value can be, for example, a consolidated voltage signal such as an effective value. The first and / or second threshold value can be set to 100 volts, for example. In the event that the measured value, for example the rms value of the voltage is above 100V (= first threshold value), which is the case with a mains voltage of 230V, the mains voltage would be applied to the at least one control conductor connection 3d the switching device 5 the supply conductor connection 3a with the power conductor connection 3c interconnect. The first operating state preferably also provides that the control and communication device 7 is designed for the switching device 5 to be controlled such that the interconnection between the at least one power conductor connection 3c and the supply conductor connection 3a interrupts if the signal value or the RMS value of the electrical signal at the at least one control conductor connection 3d falls below a predetermined second threshold value. For example, the second threshold value can correspond to an effective value of 50V. Would this, for example, by separating the two connections 16a . 16b the on / off switch 16 the switching device would fall below 5 are controlled in such a way that these the electrical consumer 15 from the supply conductor connection 3a switches off.

The first and second threshold values can be chosen to be identical or different. The latter case is preferred because it avoids switching back and forth too often at the same limit.

Basically, the control switch module 1 the own switching device does not do this either 5 to press and instead a module message 10 with switching information 10a generate and send it wirelessly. However, this will be discussed later with regard to the 5 and 6 explained.

The second operating mode, also called edge control, is set in the event that it is the on / off switching device 16 is a button. Such a button is for example in the 6 shown. When a button is pressed, the two connections 16a . 16b the on / off switch 16 be connected to each other only for a certain (short) period of time. Would be the control and communication facility 7 in the first mode of operation, then it would be the electrical consumer 15 briefly with the supply conductor connection 3a connect and then disconnect again.

1. (i) eine bestehende Zusammenschaltung des zumindest einen Leistungsleiter-Anschlusses 3c mit dem Versorgungsleiter-Anschluss 3a unterbricht; oder
2. (ii) den zumindest einen Leistungsleiter-Anschluss 3c bei einer fehlenden Zusammenschaltung mit dem Versorgungsleiter-Anschluss 3a zusammenschaltet.

Jedes Mal, wenn der Taster betätigt wird, findet daher genau ein Wechsel, also eine Änderung des Schaltzustands statt. Ergänzend oder alternativ dazu kann auch noch eine Modulnachricht 10 generiert und drahtlos ausgesendet werden, die eine entsprechende Schaltinformation 10a beinhaltet. Diese Schaltinformation 10a bewirkt bei dem empfangenden Steuer-Schaltmodul 1b, 1c, dass dieses einen Wechsel seines Schaltzustands vornimmt. Dieser Betriebsmodus wird auch dann eingesetzt, wenn eine „Treppenhausbeleuchtung“ mit mehreren Tastern realisiert werden soll. In diesem Fall gibt es zumindest ein Steuer-Schaltmodul 1, welches mit einer Lampe 15 verbunden ist. Dieses empfängt drahtlose Modulnachrichten 10 von anderen Steuer-Schaltmodulen 1a, 1b, 1c, die mit den Tastern verbunden sind. Das Betätigen eines dieser Taster führt immer dazu, dass sich der Betriebszustand des elektrischen Verbrauchers (Lampe) 15 ändert. Ist sie ausgeschalten, dann wird sie eingeschalten und umgekehrt. Siehe hierzu 6. The control switching module is in the second operating mode 1 and in particular the control and communication device 7 configured such that it only reacts to a rising or falling level or edge of the electrical signal. The control and communication device 7 is designed in the second operating mode for the case that the measured value at the at least one control conductor connection 3d the switching device exceeds or falls below the first threshold value 5 to be controlled in such a way that:

1. (i) an existing interconnection of the at least one power conductor connection 3c with the supply conductor connection 3a interrupts; or
2. (ii) the at least one power conductor connection 3c if there is no interconnection with the supply conductor connection 3a interconnects.

Every time the button is pressed, there is exactly one change, i.e. a change in the switching state. In addition or alternatively, a module message can also be added 10 generated and transmitted wirelessly, the corresponding switching information 10a includes. This switching information 10a causes at the receiving control switch module 1b . 1c that this changes its switching state. This operating mode is also used when "staircase lighting" with several buttons is to be implemented. In this case there is at least one control switching module 1 which with a lamp 15 connected is. This receives wireless module messages 10 from other control switch modules 1a . 1b . 1c associated with the buttons. Pressing one of these buttons always results in the operating state of the electrical consumer (lamp) 15 changes. If it is switched off, then it is switched on and vice versa. See also 6 ,

The control and communication device 7 is designed in particular to the switching device 5 to be controlled such that this interconnection between the at least one power conductor connection 3c and the supply conductor connection 3a interrupts in the zero current crossing. It is by means of the measuring device 8th a measured value is recorded in the form of the current profile. The wording “capture” is not only to be understood in such a way that digital measurement values are captured by means of an A / D converter, but also in that the switching process in the switch device is by means of an analog circuit 5 is only triggered at zero current.

5 shows an exemplary second application of the control switching module according to the invention 1 which is in a building control facility 2 is integrated. In this case a door lock can be controlled. In this case there are several control switch modules 1 . 1a . 1b , A first control switch module 1 only serves to connect a voltage signal to the control conductor 3d to detect. In this case it is the on / off device 16 around a keypad with which a key combination can be entered. Once the correct key combination has been entered, a voltage level from this on / off device 16 to the control conductor connection 3d of the first control switching module 1 spent. The control and communication device 7 detects this voltage signal and generates a module message 10 that this switching information 10a includes. The module message 10 is connected to the other control switching modules 1a . 1b wirelessly transmitted. These other control switch modules 1a . 1b do not react to any electrical signals on their control conductor connections 3d , These control wire connections 3d are preferably not connected (open) or permanently connected to a ground potential.

The first control switch module 1 therefore acts as a transmitter or as a transmission control switching module 1 or master control switching module 1 , whereas the other control switch modules 1a . 1b as a receiver or as a receiver control switching module 1a . 1b or as slave control switching modules 1a . 1b act or are configured as such. These other control switch modules 1a . 1b are designed depending on the control switching module 1 received module message 10 that have a switching information 10a includes their switching devices 5 to be controlled such that it connects the at least one power conductor 3c with the supply conductor connection 3a interconnect or interrupt an existing interconnection.

In 5 is the at least one power conductor connection 3a of another control switching module 1a with a first coil 15a connected, whereas the at least one power conductor connection 3c of the other control switch module 1b with another coil 15b is electrically connected. Both coils 15a . 15b are part of a locking device that also acts as an electrical consumer 15 can be designated. This locking device comprises a locking element 19 , especially in the form of a locking bolt. Whichever of the two coils 15a . 15b is energized, the locking element 19 moved one way or the other. In principle, it would also be possible for only one additional control switching module 1a is used, which is one coil 15a is a moving coil, and wherein a permanent magnet is used to the locking element 19 to press permanently into a state in which a door arrangement is locked.

The control and communication device 7 is designed in this case, the switching device 5 to be controlled such that it connects the at least one power conductor 3c with the supply conductor connection 3a interconnects only for a certain period of time. In principle, it would also be possible for the at least one power conductor connection 3c with the supply conductor connection 3a is only connected in a pulsed manner, that is, an analog electrical connection between the at least one power conductor connection 3c and the supply conductor connection 3a will be produced. The way the control and communication device 7 the switching device 5 controls, can in the context of configuration information 10c of the corresponding control switch module 1 . 1a . 1b can be set. This can be done at the factory or later without contact by a user. For the latter, the module message includes 10 a configuration information 10c , In principle, it would also be possible to include this information in the switching information 10a to pack and as a module message 10 to send.

It would also be possible for a control switching module 1 several power conductor connections 3c comprises, independently of one another by the switching device 5 with the supply conductor connection 3a can be interconnected. With respect to 5 it would therefore just be another control switching module 1a need.

In addition to a keypad, the on / off device 16 also include a motion detector. In this case there would be an output of the motion detector with the control wire connection 3d of the at least one control switching module 1 connected. This would detect a corresponding electrical signal and a module message 10 to other control switch modules 1a . 1b to ship. The other control switch modules 1a . 1b are configured to only provide switching information 10a of module news 10 accept and run by the designated or authorized control switch module 1 come. Which control switch module 1 authorized in the other control switching modules 1a . 1b by means of configuration information 10c within a module message 10 be transmitted.

6 shows a third application of the control switching module according to the invention 1 which is in a building control facility 2 is integrated. In this case, the electrical consumer 15 through several control switch modules 1a . 1b . 1c with the public power grid 4 get connected.

In 6 there is a control switch module 1 whose power conductor connection 3c im the electrical consumer 15 connected is. The control wire connection 3d of the control switching module 1 is not connected to any other device.

There are also other control switching modules 1a . 1b . 1c , Your control wire connection 3d is with a second connection 16b an on / off switch 16 connected. The first connection 16a is again with the supply manager 4a of the public power grid 4 connected. With the on / off switch 16 in this case it is a button. The other control switch modules 1a . 1b . 1c operate in the second operating mode. As soon as a measured value of the electrical signal at the at least one control conductor connection 3d The respective control and communication device is above or below a first threshold value 7 trained to send a module message 10 to generate the switching information 10a includes. This module message 10 is then sent to the control switch module 1 sent. The control switch module 1 is trained to send this module message 10 wirelessly received and the own switching device 5 to be controlled such that it connects the at least one power conductor 3c with the supply conductor connection 3a interconnects or interrupts an existing interconnection.

In the 6 The cabling shown is used in particular to control a light network if a plurality of light switches in the form of buttons are provided, which have at least one electrical consumer 15 switch on or off in the form of a lamp. Each switch, regardless of the sequence in which it is actuated, can have an electrical consumer switched on 15 switched off and a switched off electrical consumer 15 be switched on. The control switch modules 1a . 1b and 1c are in the second operating mode here.

In the event that, instead of buttons, switches as an on / off switch 16 the control switch modules would have to be used 1a . 1b and 1c be operated in a third operating mode. Here you need the measured value for the electrical signal at your at least one control conductor connection 3d Examine for both a rising edge and a falling edge. With each edge change, the control switching modules 1a . 1b and 1c now a module message 10 with switching information 10a to the control switch module 1 transmitted, so that this changes or changes its switching state.

For example, the use of a dimmer in the on / off switching device is not shown 16 , In this case the control switching modules would have to 1a . 1b and 1c in a fourth Operating mode. Such a dimmer comprises, for example, a phase control or a phase control. The control switch module 1 recognizes in particular those intervals of a period of the electrical signal at the control conductor connection in the fourth operating mode 3d that are zero or close to zero. The control and communication device generates in accordance with the phase-cut or phase-cut signal 7 a module message 10 with corresponding switching information 10a so that the control switch module 1 , at its power conductor connection 3c the electrical consumption 15 is connected, makes an analog electrical interconnection, which leads to the electrical consumer 15 A corresponding dimming also takes place, ie also the same phase-cut or phase-cut signal by the switching device 5 is issued. Changes also include less than 25%, 20%, 15%, 10% or 5%.

Such a phase-cut or phase-cut electrical signal is recognized by the measuring device 8th . 8a which can contain an A / D converter for this purpose. The measuring device 8th . 8a can, for example, in the control and communication device 7 be arranged. In the simplest case, the control and communication device 7 comprise one or more A / D converters. When the dimmer is adjusted, the signal / pause ratio changes. The measured value in the form of a consolidated voltage and / or current value in the form of the effective value changes. This change is recognized and, accordingly, the switching device 5 instructed to set the interconnection accordingly. This is also to be understood to mean that the interconnection, which in this case establishes an analog electrical connection, continuously follows a signal change at the control conductor connection 3d is adjusted. Even the switching information 10a that are optional or complementary in a module message 10 can be sent will be adjusted accordingly. The same also applies if the electrical signal is pulse width modulated or frequency modulated.

7 shows an exemplary structure of a module message 10 , The module message 10 can include a device-dependent identification (e.g. number) for each control switching module used 1 is different. In addition, this can also contain switching information 10a include. This switching information 10a can be in different forms. For example, it would be possible for the switching information 10a would only be marked as active, for example with a binary "1". A control switch module 1 which is such a module message 10 would get in this case the at least one power conductor connection 3c with the supply conductor connection 3a interconnect. Would be the switching information 10a not marked, for example with a binary "0", the control switch module would 1 which this module message 10 receives an interconnection between the at least one power conductor connection 3c and the supply conductor connection 3a interrupt. Basically, the switching information 10a also include another binary value in order to set the type of interconnection (digital, analog) with the respective parameters or to set the correct power conductor connection 3c select. The switching information 10a can also contain a switching group information, based on which receiving control switching modules 1 . 1a . 1b . 1c can recognize whether they are on the switching information 10a that contain a switching command, should react or not. Namely, the control switch modules 1 . 1a . 1b . 1c in this case, only react to corresponding switching commands if they have acquired such group membership during configuration. The switching information can also include information for establishing an analog electrical connection.

Furthermore, the module message 10 still measurement information 10b contain. This measurement information 10b can be measured values for certain physical quantities that the measuring device 8th in the control switch module 1 can capture.

In addition, a module message 10 still configuration information 10c include. This configuration information 10c can, for example, indicate whether the control and communication device 7 is operated in the first, second, third or fourth operating mode.

Optionally, you can use the configuration information 10c group memberships are also awarded.

The configuration information 10c can also include a switch setting. This switch setting indicates how the control and communication device 7 the switching device 5 should drive. For example, it is possible that the switching device 5 the at least one power conductor connection 3c as long as with the supply conductor connection 3a interconnected until the control and communication device 7 requires an interruption. It is also possible that this interconnection takes place only for a certain time interval, this time interval being fixed in the control switching module 1 programmed or also via the configuration information 10c can be obtained. Basically, the type of interconnection can also be entered here, i.e. whether a digital electrical connection or an analog electrical connection between the at least one power conductor connection 3c and the supply conductor connection 3a should be done. In the case of a pulsed analog electrical connection, for example, the pulse-pause ratio in the control switching module 1 permanently programmed or also via configuration information 10c related. In such a case, one would speak of the switching device 5 assumes an analog state.

However, this switch setting can also contain so-called master information, which expresses whether a receiving control switch module should temporarily ignore or resume all switch commands without master information and switch commands that would be triggered by a signal change in the control conductor connection .

If no MESH communication is provided for the control switching module, the configuration information can 10c also indicate whether the control switch module 1 should work as a repeater and all or selected received module messages 10 should forward or whether the control switching module 1 only on switching information 10a should respond to it in a module message 10 receives, regardless of the electrical signal on its own control conductor connection 3d , In the case of MESH network communication, the repeater function would not have to be configured explicitly, since each MESH node automatically takes over a repeater function. Conversely, the control switching module could also apply 1 only its own control wire connection 3d should monitor and corresponding switching information 10a created, which in turn as a module message 10 be sent without having to control your own switching device 5 he follows.

The configuration information 10c can also contain information as to whether the control switching module 1 in the event that a current value or a sequence of current values is detected which is or are above a threshold value, should output a fault current at the protective conductor connection.

The module message 10 can also also contain status information 10d, which is of a general nature and indicates, for example, whether the control switching module 1 has any malfunction.

The module message 10 can also add log information 10e include which the control switch module 1 indicates what measurement information 10b the control and switching module 1 through its measuring device 8th capture and as a module message 10 to send. This allows the central control device 20th and / or the mobile terminal 21 targeted measured values of individual control switch modules 1 . 1a . 1b be queried.

8th shows a simplified embodiment of the building control device according to the invention 2 , This includes at least one control switch module 1 and in the case of 8th several control switch modules 1 . 1a . 1b , The control switch modules 1 . 1a . 1b are designed to form a peer-to-peer network, a mesh network, a scatter network, a daisy chain network or a tree network, so that the module message 10 of the at least one control switching module 1 via at least one further control switching module 1a is transmitted until it ends up being controlled by another control module 1b Will be received.

Depending on the protocol used, this may even be absolutely necessary with a certain number of participants (= control switching modules 1). With a "classic" Bluetooth ^® connection, a master can communicate with a maximum of seven slaves (eg Pico network). Therefore, it would be imperative here that from eight control switch modules 1 . 1a . 1b . 1c the module news 10 of the other control switch modules 1 . 1a . 1b . 1c via other control switch modules 1 . 1a . 1b . 1c are routed or routed.

The building control system 2 comprises a central control device 20th , This is designed to send module messages 10 to the at least one control switching module 1 . 1a . 1b to transmit wirelessly, these module messages 10 Switching information 10a and / or configuration information 10c and / or protocol information 10e contain. The central control device 20th is also trained to module messages 10 from the at least one control switching module 1 . 1a . 1b to receive, these module messages 10 Measurement information 10b and / or status information 10d contain.

The central control device 20th is also trained to deliver module news 10 to a mobile device 21 to transmit a user or module messages 10 from the mobile device 21 to recieve. With the mobile device 21 it is in particular a computer, a smart tablet or a smartphone.

On the mobile device 21 a graphical user interface is preferably installed, which allows the individual control switch modules 1 . 1a . 1b an electrical consumer 15 to be stored and preferably specified more precisely, for example by entering a name or type. The central control device 20th is then able to generate energy statistics and sent to the mobile device 21 to transmit. The mobile device 21 can the energy statistics related to the respective electrical consumers 15 corresponds to represent graphically so that a user electrical consumer 15 can locate those who use an above-average amount of energy.

Via the mobile device 21 or the central control device 20th can also module messages 10 in the form of configuration information 10c to the control switch modules 1 . 1a . 1b which are sent to the individual control switching modules 1 . 1a . 1b communicate on which wirelessly transmitted module messages 10 of which control switch modules 1 . 1a . 1b with what behavior you have to react.

Via the mobile device 21 can add more module messages 10 to the central control device 20th are transmitted in addition to precise switching information 10a still contain time information, the central control device 20th comprises a time device and is designed to provide the switching information 10a , at which time information is also stored, at the specific times stored in the time information to the respective control switching module 1 . 1a . 1b to send. This allows electrical consumers to be targeted 15 activated at certain times and days of the week. For example, the lighting can be switched on automatically at dusk and the roller shutters lowered. It is also possible for lighting scenarios to be created, so that lighting conditions in the building which change over time are achieved even in the absence of a resident, as a result of which the building looks inhabited. In addition to time information, energy cost information or energy generation information can also be provided together with the switching information 10a in a module message 10 be transmitted. In the event that, for example, your own photovoltaic system or your own energy generator is installed on the building, certain electrical consumers can 15 via their respective control switch modules 1 . 1a . 1b then be switched on when this energy producer provides a performance that is above a preset threshold. In particular, energy-hungry electrical consumers 15 such as washing machines or dryers are turned on when the photovoltaic system is performing well.

The same applies if energy cost information is transmitted. It is thus possible for energy suppliers to offer flexible energy costs, with the energy costs being higher during peak load times than during low load times. The central control device 20th is then designed to corresponding control switching modules 1 . 1a . 1b only then by means of appropriate switching information 10a in a module message 10 turn on when the energy costs fall below a predetermined or adjustable threshold.

The central control device 20th in this embodiment also includes a microphone 22 , Via the microphone 22 voice commands can be received and evaluated. The central control device 20th is trained to use these voice commands in module messages 10 to translate and to the at least one control switching module 1 . 1a . 1b to transmit.

The 9A and 9B show a further embodiment of the building control device according to the invention 2 , This can, for example, on all floors 24 of a building 25th be installed. In 9B is such a floor 24 shown which multiple rooms 24a . 24b and 24c includes. The individual rooms 24a . 24b and 24c are connected by doors. Is shown in 9B that in every room 24a . 24b and 24c several control switch modules 1 are arranged. Preferably is on each control switch module 1 exactly an electrical consumer 15 connected. Of course, several electrical consumers can also be used 15 his. So individual switching control modules 1 be responsible for controlling the shutters or blinds, whereas other control switch modules 1 for lighting the rooms 24a . 24b . 24c are responsible. The central control device 20th is preferably also in one of these rooms 24a . 24b . 24c arranged. This central control device 20th is preferably with the mobile device 21 connected via an internet connection or an intranet connection (e.g. WLAN). There could also be a Bluetooth ^® connection.

As already explained, a control switching module 1 . 1a . 1b several control conductor connections 3d and several power conductor connections 3c comprise, preferably in each case a control conductor connection 3d to a power conductor connection 3c corresponds. A corresponding electrical signal on a control conductor connection 3d leads to interconnection or disconnection of the interconnection at the corresponding power conductor connection 3c and the supply conductor connection 3a , The power conductor connections 3c can of course also be grouped so that a corresponding electrical signal on a control conductor connection 3d or a switching information 10a causes multiple power conductor connections 3c with the supply conductor connection 3a be interconnected or an interconnection is interrupted. Different types of interconnection can be set at different times.

The control switch module 1 According to the invention can also be used in a garden lighting control or generally where currents and voltages are to be switched.
