Description

The invention relates to a method for providing measurement data from sensor devices in a building using at least one transmission module through wireless data communication. The invention also relates to a transmission module for such a method.

According to the EU Energy Efficiency Directive, only remotely readable meters and heat cost allocators should be used in buildings. For this purpose, sensor devices with a radio interface should preferably be used, which provide their respective measurement data by wireless data transmission. The remote reading can be performed, for example, with a suitable computer device that can decode the measurement data. Readings can be taken from the hallway, for example, without having to enter each individual apartment.

The present invention is based on the object of further simplifying and optimizing the remote reading of such sensor devices.

1. a) in dem Gebäude wird das wenigstens eine Übertragungsmodul in Funkreichweite der Sensoreinrichtungen installiert und ohne die Notwendigkeit manueller Konfiguration automatisch in Betrieb genommen,
2. b) das in Betrieb genommene Übertragungsmodul nimmt die Messdaten von verschiedenen Sensoreinrichtungen mittels einer ersten Funkschnittstelle des Übertragungsmoduls über ein Messdaten-Übertragungsprotokoll drahtlos auf,
3. c) das Übertragungsmodul überträgt die Messdaten mittels einer zweiten Funkschnittstelle des Übertragungsmoduls drahtlos direkt oder indirekt über eines oder mehrere weitere Übertragungsmodule über das Internet an einen mit dem Internet verbundenen Server,
4. d) der Server entschlüsselt die Messdaten und nimmt sie in eine Messdaten-Datenbank auf.

This object is achieved by a method of the type mentioned at the outset with the following features:

1. a) the at least one transmission module is installed in the building within radio range of the sensor devices and automatically put into operation without the need for manual configuration,
2. b) the commissioned transmission module wirelessly records the measurement data from various sensor devices using a first radio interface of the transmission module via a measurement data transmission protocol,
3. c) the transmission module uses a second radio interface of the transmission module to wirelessly transmit the measurement data directly or indirectly via one or more further transmission modules via the internet to a server connected to the internet,
4. d) the server decrypts the measurement data and records them in a measurement data database.

According to the invention, easy-to-install and easy-to-use transmission modules are used, which enable the measurement data to be transmitted over the Internet. Because the measurement data are recorded on an Internet server and transferred to a measurement database, they are easily accessible for a wide range of other uses. A further advantage of the invention is that the measured data transmitted in encrypted form by the sensor devices, as a rule, does not have to be decrypted locally, but instead the decryption takes place centrally on the server. This further simplifies the commissioning of the transmission modules, since they do not have to know the respective encryption codes of the different sensor devices, but can generally transmit the recorded data on to the server without decryption.

The sensor devices can, for example, be in the form of calibrated counters. The measurement data encrypted by the sensor devices can be provided with additional encryption in one or more transmission modules in order to secure the data transmission to the server. The transmission module can also collect data from other wirelessly connectable devices and transmit it to the server. The measurement data transmission protocol can be a standardized measurement data transmission protocol.

The first radio interface can be a multi-frequency radio interface or a broadband radio interface, e.g. for receiving data in the frequency range of 433-999.99 MHz, in particular 868 and 915 MHz. The second radio interface can be a WLAN or WiFi interface. The first radio interface can be unidirectional (transmission module can only receive data from the sensor devices) or bidirectional (transmission module can also send data to the sensor devices or other devices).

The second radio interface can be unidirectional (transmission module can only send data to other transmission modules and/or to the server) or bidirectional (transmission module can additionally receive data from other transmission modules and/or from the server).

The invention makes it possible, in addition to multi-frequency reception and the transmission of measurement and sensor data, to improve the transmission and addressing of all participants up to the forwarding of the data in encrypted form via an MQTT broker to the server side through standardization and automation.

1. a) in dem Gebäude werden mehrere Übertragungsmodule an verschiedenen Stellen jeweils in Funkreichweite einer dem jeweiligen Übertragungsmodul zugeordneten Gruppe von Sensoreinrichtungen installiert und ohne die Notwendigkeit manueller Konfiguration automatisch in Betrieb genommen,
2. b) die in Betrieb genommenen Übertragungsmodule bilden über ihre jeweilige zweite Funkschnittstelle automatisch ein selbstorganisierendes Mesh-Funknetzwerk,
3. c) jedes Übertragungsmodul nimmt die Messdaten der ihm zugeordneten Gruppe von Sensoreinrichtungen mittels seiner ersten Funkschnittstelle über das Messdaten-Übertragungsprotokoll drahtlos auf,
4. d) jedes Übertragungsmodul überträgt die Messdaten mittels seiner zweiten Funkschnittstelle direkt oder indirekt über eines oder mehrere weitere Übertragungsmodule über das Mesh-Funknetzwerk an ein mit dem Internet verbundenes Übertragungsmodul,
5. e) das mit dem Internet verbundene Übertragungsmodul überträgt die Messdaten über seine Internetverbindung an den mit dem Internet verbundenen Server,
6. f) der Server entschlüsselt die Messdaten und nimmt sie in die Messdaten-Datenbank auf.

According to an advantageous embodiment of the invention, it is provided that several transmission modules are used, with the method having the following features:

1. a) Several transmission modules are installed in the building at different points, each within radio range of a group of sensor devices assigned to the respective transmission module, and without the necessary manual configuration is automatically put into operation,
2. b) the transmission modules put into operation automatically form a self-organizing mesh radio network via their respective second radio interface,
3. c) each transmission module wirelessly records the measurement data from the group of sensor devices assigned to it using its first radio interface via the measurement data transmission protocol,
4. d) each transmission module uses its second radio interface to transmit the measurement data directly or indirectly via one or more further transmission modules via the mesh radio network to a transmission module connected to the Internet,
5. e) the Internet-connected transmission module transmits the measurement data via its Internet connection to the Internet-connected server,
6. f) the server decrypts the measurement data and includes them in the measurement data database.

In this way, a simple and inexpensive installation of the transmission modules is made possible even for relatively large buildings, for example for apartment buildings, high-rise buildings and similar buildings. Due to the fact that the transmission modules automatically form a self-organizing mesh radio network, relatively large distances can also be bridged with radio interfaces that are only suitable for short ranges. In addition, redundancy is created during transmission. In the event of a fault, the mesh wireless network can automatically reorganize itself. The transmission modules also search for new neighboring transmission modules during operation, which are included in the mesh radio network.

In addition, at least one transmission module forms a defined transmission interface to the Internet (breakout point), with the transmission module having an additional third interface for this purpose, which can be designed either as a radio interface or as a wired interface, for example as an Ethernet interface. The system can have several transmission modules connected to the internet.

According to an advantageous embodiment of the invention, it is provided that consumption data of the entire building and/or individual separate residential units of the building and warning messages are recorded as measurement data. This has the advantage that all relevant consumption data and warning messages can be recorded automatically, in particular without entering the individual residential units, and can be recorded and managed at a central location, i.e. the Internet server.

The following can be recorded as consumption data, for example: electricity consumption, gas consumption, water consumption, heat consumption, recorded e.g. by electricity meters, gas meters, water meters, heat meters, heat cost allocators. Warning messages can come from smoke detectors and/or alarm systems, for example.

According to an advantageous embodiment of the invention, it is provided that the sensor devices send out the measured data wirelessly and in encrypted form continuously, even without being queried. This has the advantage that the sensor devices do not have to be triggered by signals for sending out the measurement data. The sensor devices can transmit the measurement data, for example, in a type of free-running protocol, for example with the OMS protocol (OMS—Open Metering System) or the LoRa protocol (LoRa—Long Range).

According to an advantageous embodiment of the invention, at least one physical parameter of the ambient air is recorded by one, several or all transmission modules via at least one dedicated air sensor and is transmitted to the server together with the measurement data. For example, one, several or all of the following physical parameters of the ambient air can be recorded: air temperature, humidity, air pressure. The server can record the received parameters of the ambient air in the measurement data database. This has the advantage that the transmission modules provide additional measured values, in particular those measured values that are not usually recorded by the meters or heat cost allocators. In this way, additional knowledge about the condition and the operating parameters of the building can be recorded and further processed.

According to an advantageous embodiment of the invention, it is provided that the measurement data is transmitted to the server via an MQTT protocol. The transmission module connected to the Internet then forms an MQTT broker. As a result, the standardization and automation of the remote reading of the sensor devices can be further improved.

According to an advantageous embodiment of the invention, it is provided that an actuator that can be controlled via radio signals can also be present in the building, with the at least one transmission module transmitting control commands via the second Radio interface receives from the Internet directly or indirectly via one or more other transmission modules and transmits the control commands via the first radio interface to the possibly existing one controllable actuator. This has the advantage that the transmission module can also be used to actively influence functions or elements in the building, for example to control the ventilation of a stairwell, or to switch light sources on or off or dim them.

1. a) wenigstens einen Rechner, einen Speicher und ein in dem Speicher gespeichertes Computerprogramm,
2. b) eine erste Funkschnittstelle, wobei das Übertragungsmodul dazu eingerichtet ist, die Messdaten von verschiedenen Sensoreinrichtungen mittels der ersten Funkschnittstelle über ein Messdaten-Übertragungsprotokoll drahtlos aufzunehmen, wenn das Computerprogramm auf dem Rechner ausgeführt wird,
3. c) eine zweite Funkschnittstelle, wobei das Übertragungsmodul dazu eingerichtet ist, die aufgenommenen Messdaten mittels der zweiten Funkschnittstelle drahtlos direkt oder indirekt über eines oder mehrere weitere Übertragungsmodule über das Internet an einen mit dem Internet verbundenen Server zu übertragen, wenn das Computerprogramm auf dem Rechner ausgeführt wird,
4. d) wobei das Übertragungsmodul dazu eingerichtet ist, über die zweite Funkschnittstelle benachbarte Übertragungsmodule zu erkennen und mit diesen ein selbstorganisierendes Mesh-Funknetzwerk zu bilden, wenn das Computerprogramm auf dem Rechner ausgeführt wird.

The object mentioned at the outset is also achieved by a transmission module for a method of the type explained above, the transmission module having the following features:

1. a) at least one computer, a memory and a computer program stored in the memory,
2. b) a first radio interface, wherein the transmission module is set up to wirelessly record the measurement data from various sensor devices using the first radio interface via a measurement data transmission protocol when the computer program is executed on the computer,
3. c) a second radio interface, wherein the transmission module is set up to wirelessly transmit the recorded measurement data using the second radio interface directly or indirectly via one or more further transmission modules via the Internet to a server connected to the Internet when the computer program is running on the computer will,
4. d) the transmission module being set up to recognize neighboring transmission modules via the second radio interface and to form a self-organizing mesh radio network with them when the computer program is executed on the computer.

A uniform transmission module is thus provided for use in the method explained at the outset. The transmission module can be designed relatively simply and inexpensively, for example as a handy box that can be installed relatively unobtrusively in a stairwell of a building. Due to its several radio interfaces, the transmission module can very efficiently carry out the method steps explained above, in particular the recording of the measurement data from the sensor devices and the further transmission via the Internet to the server.

According to an advantageous embodiment of the invention, it is provided that the transmission module is set up to recognize whether it is connected to the Internet, and if it is connected to the Internet, the measurement data received from other transmission modules of the mesh radio network via its Internet connection to the Transfer server when the computer program is running on the computer. In this way, the transmission module can configure itself in such a way that it automatically forms the breakout point to the Internet for the wireless mesh network. The measurement data can be transmitted to the server via an MQTT protocol. The transmission module connected to the Internet then forms an MQTT broker. The Internet connection of the transmission module can be formed by a wireless or wired interface, e.g. Ethernet interface.

According to an advantageous embodiment of the invention, it is provided that the transmission module has at least one air sensor for detecting a physical parameter of the ambient air, the transmission module being set up to transmit sensor data from the at least one air sensor directly or indirectly via the second radio interface via one or to transmit several further transmission modules over the Internet to the server when the computer program is running on the computer. This has the advantage that additional measured values are provided by the transmission modules.

In the case of the invention, at least one transmission module, possibly also a main transmission module, is used, which uses a WiFi mesh network and its own mesh initialization method. In the inventive solution, loT real-time processing for measurement and sensor data is combined using the transmission modules and the MQTT protocol.

In one embodiment, the invention relates to a transmission module with at least one radio processor for detecting and controlling radio devices (sensors and/or actuators) in connection with a communication processor for data transmission in an automatically generated and self-organizing mesh radio network, with a transmission of received measurement and sensor data and also locally obtained sensor data via an MQTT standard, also using a WiFi mesh network.

The measurement data are received from the first radio interface present in the transmission module, e.g. an 868/915 MHz radio module, e.g. as an OMS protocol (OMS - Open Metering System)/LoRa packets, and by means of a computer, e.g. a processor, further processed. This data is in this state for the most part Share encrypted, with a few percent unencrypted and thus readable in plain text after processing in the processor. Encrypted data is not decrypted in the transmission module, since the transmission module does not hold this key, or does not have to hold it at all. These measurement and sensor data can be transferred to another processor, they can be encrypted again and transmitted via WiFi to other transmission modules, if necessary, up to an MQTT broker. A microservice can listen to this MQTT broker, which sorts and processes the incoming data packets and searches a database for the stored keys and, if these are available, qualifies the data packets, i.e. breaks them down into the individual components, such as measured values, units, time stamps, and then writes it to a database.

According to the further description of the inventive solution, the transmission method is referred to as BRICK-loT protocol and a transmission module as BRICK. Measurement and sensor data from wireless devices, for example from meters, smart meters, electricity, gas, water, heat, smoke detectors, sensors and actuators as well as from other wireless devices that can be connected, can be recorded and transmitted.

1. 1. Übertragungsmodul mit inkludierten Radiomodulen zum Empfang der Funkdaten im Bereich 433,00 MHz bis 999,99 MHz
2. 2. Radio-Prozessor zur Abbildung der Radiodaten in ein Protokoll wie zum Beispiel OMS (Open Metering System) oder LoRa (ver- und entschlüsselt) je nach dem Ursprung der Daten, nach den gängigen Standards
3. 3. Kommunikations-Prozessor zur Kommunikation der Mess- und Sensordaten über ein WiFi-Mesh-Netzwerk an einen definierten Endpunkt wie einen Datenbroker, über MQTT.

Embodiment of the BRICK (transmission module):

1. 1. Transmission module with included radio modules for receiving radio data in the 433.00 MHz to 999.99 MHz range
2. 2. Radio processor for mapping the radio data into a protocol such as OMS (Open Metering System) or LoRa (encrypted and decrypted) depending on the origin of the data, according to the common standards
3. 3. Communications processor for communicating the measurement and sensor data via a WiFi mesh network to a defined endpoint such as a data broker, via MQTT.

Embodiment of the BRICK-IOT protocol:

The BRICK-IOT protocol starts with the data assembled from the radio data. These are passed from the radio processor for mapping the data to the WiFi processor for communicating the data. This communication processor communicates via the mesh radio network, e.g. a BRICK-IOT-MESH network, to a defined endpoint, e.g. a data broker. The BRICK-IOT-MESH network is self-organizing and can be expanded with any number of BRICKs.

A WiFi mesh system is basically already known from the prior art. However, particularly in the case of extensive systems that are composed of a large number of modules, the addressing of all participants in a mesh system repeatedly poses problems or is very complex, since a great deal of address programming is required for each individual system.

In one embodiment, the invention relates to a transmission module with at least one receiving unit for measurement and sensor data, with a multi-frequency reception input and a transmission output, wherein the transmission output can also be a transmission input (mesh) at the same time. The transmission inputs and transmission outputs are cascadable, and all transmission modules are interconnected via multiple cascades.

The invention thus includes structures such as tree and/or network structures being able to occur in parallel in a mesh radio network. The entire mesh radio network organizes itself permanently. This is based on the knowledge that reception and transmission conditions in a WiFi network can change relatively quickly.

The invention makes it possible to set up a completely automatic transmission system for measurement and sensor data that does not require any addressing or configuration.

The system is completely self-organizing. According to one embodiment of the invention, all reception and transmission modules are designed as a multi-frequency reception system. This allows the transmission module to receive various measurement and sensor data from wireless devices in buildings on different frequencies in the range from 433.00 to 999.99 MHz data packets.

Since, according to one embodiment of the invention, each transmission module can be both a transmitter and a receiver, e.g. in a mesh radio network, the configuration can take place automatically via all accessible transmission modules (neighboring systems). A transmission module declares itself as a "master system" when it detects connectivity with a defined broker. All master systems have the ability to communicate with the broker via an additional interface via the WiFi network. This "I have a breakout" configuration is one of the essential pieces of information that is communicated to all directly reachable transmission modules in the mesh radio network (neighboring systems).

According to one embodiment of the invention, a distance variable can be set to zero to identify the quality of this breakout. The neighboring systems remember the route and add one to the distance and pass the information on to their neighboring systems. If a neighboring system does not yet have a way out of the mesh wireless network, it saves this information, adds one and passes it on to its direct neighboring systems. This creates both chain, tree and network structures in which each transmission module finds at least one path independently, directly or via neighboring systems from the mesh radio network. If a transmission module loses a neighbor through whom the "breakout" from the mesh radio network was known, the breakout information and distance is discarded and queried again through the other directly accessible neighboring systems. This results in a completely self-configuring overall system.

Also part of the invention is the configuration with more than one breakout point in a network. The self-configuration procedure can then be identical to that described above.

If actuators, such as switches, are present on a transmission module, the relevant neighboring systems are notified with the actuator number.

This means that the breakout information flows from the “breakout” to the transmission modules, and the actuator information flows from the transmission modules in the direction of the breakout module (bottom-up and top-down). The initialization routines of all transmission modules can include the function of constantly searching for new neighboring systems.

According to one embodiment of the invention, no knowledge of neighbors, neighbor actors, or breakout information is permanently stored in a transmission module. After a power failure, for example, each transmission module reorganizes itself from scratch according to the initialization routine.

Reset/Restart: According to one embodiment of the invention, a function is implemented that discards all breakout and actuator information and causes an initialization, as with a restart. This allows various start scenarios to be mapped / circumvented that can occur in the event of large-scale failures, the entire network is reorganized. The reset state can be sent to a transmission module via the MQTT broker or by the physical intervention of an on-site technician who introduces a reset module into the network. A reset module broadcasts the reset information, transmission modules receive the reset command, forward it to visible neighbors and then reset themselves.

With the present invention, adding a transmission module to an existing network is a welcome event as it stabilizes the network and creates more meshes and paths for communication.

The removal of a transmission module from the network does not automatically lead to its collapse, since automatic reorganization occurs or other ways to a breakout are known in the network.

Advantageous embodiments of the transmission modules:

1. 1. Aufbaumontage:
   • Bei der Aufbaumontage existieren zwei Arten der Spannungsversorgung:
     1. a) USB 5-Volt-Gleichstrom
     2. b) 110-240-Volt-Wechselstrom.
2. 2. Hinterputzmontage:
   • Bei der Hinterputzmontage kommen 5-/12-Volt Gleichstrom oder 110-240-Volt-Wechselstrom zum Einsatz. Diese Bauform ist auf die Größe einer Unterputzsteckdose mit halber Bauhöhe ausgelegt, womit das Übertragungsmodul hinter einer handelsüblichen Steckdose oder einem Schalter platziert werden kann.
3. 3. Hutschienenmontage:
   • Bei der Hutschienenmontage existiert nur die 110-240 Volt Variante. Das Gerät ist zwei Teilungeinheiten (2 TE) breit.

The designs can be divided into three classes. The functionality is the same for all classes.

1. 1. Surface mounting:
   • There are two types of power supply for surface mounting:
     1. a) USB 5 volt DC power
     2. b) 110-240 volt AC.
2. 2. Back plaster mounting:
   • For flush mounting, 5/12 volt direct current or 110-240 volt alternating current are used. This design is designed for the size of a half-height flush-mounted socket, which means that the transmission module can be placed behind a standard socket or switch.
3. 3. DIN rail mounting:
   • With top-hat rail mounting, there is only the 110-240 volt variant. The device is two pitch units (2 HP) wide.

• Jedes Übertragungsmodul erhält bei der Herstellung eine eindeutige Bezeichnung. Diese Bezeichnung wird zur Adressierung der empfangenen und selbst generierten Daten genutzt, um damit eine eindeutige Subscriberinformation nach dem MQTT-Standard aufzubauen. Somit ist jeder Wert auf der Serverseite seinem genauen Ursprung zuweisbar.

According to one embodiment of the invention, the following data addressing can be used:

• Each transmission module is given a unique designation during manufacture. This designation is used to address the received and self-generated data in order to create unique subscriber information according to the MQTT standard. Thus, each value on the server side is assignable to its exact origin.

• Empfängt ein Übertragungsmodul Messdaten über die erste Funkschnittstelle oder stehen lokale Daten (Systeminformation, lokale Mess- und Sensordaten) zur Weiterleitung an, werden die Daten an Nachbarsysteme, d.h. benachbarte Übertragungsmodule, mit der Breakout-Information weitergeleitet. Das Nachbarsystem empfängt die Daten, behandelt diese Daten wie einen Eingang und leitet diesen ebenfalls weiter. Somit gelangen die Daten automatisch durch das Netzwerk und über einen „Breakout“ und dem MQTT-Protokoll zu dem Server.
• Soweit ein Rechner erwähnt ist, kann dieser dazu eingerichtet sein, ein Computerprogramm, z.B. im Sinne von Software, auszuführen. Der Rechner kann als handelsüblicher Computer ausgebildet sein, z.B. als PC, Laptop, Notebook, Tablet oder Smartphone, oder als Mikroprozessor, Mikrocontroller oder FPGA, oder als Kombination aus solchen Elementen.

According to one embodiment of the invention, the following data transmission can be used:

• If a transmission module receives measurement data via the first radio interface or if local data (system information, local measurement and sensor data) is to be forwarded, the data is forwarded to neighboring systems, ie neighboring transmission modules, with the breakout information. The neighboring system receives the data, treats this data as an input and also forwards it. Thus, the data automatically gets through the network and via a "breakout" and the MQTT protocol to the server.
• If a computer is mentioned, it can be set up to run a computer program, eg in the sense of software. The computer can be designed as a commercially available computer, for example as a PC, laptop, notebook, tablet or smartphone, or as a microprocessor, microcontroller or FPGA, or as a combination of such elements.

The invention is explained in more detail below on the basis of exemplary embodiments using drawings.

Show it

• 1 the provision of measurement data from sensor devices in a building and
• 2 the transmission of the measurement data to a server and
• 3 a transmission module.

the 1 shows a building 1 by way of example in the form of a block of flats (high-rise building) with eight floors and three staircases 4, 5, 6. The respective residential units 2 are accessible via the staircases 4, 5, 6. Sensor devices 3 are installed in the residential units 2, for example calibrated meters for electricity, cold water, hot water, heat cost allocators or heat meters and warning devices such as smoke alarms. The sensor devices 3 continuously transmit their measurement data independently via a radio interface. In addition, other OMS devices can also be read, such as temperature sensors, opening detectors, humidity meters, etc., but also OMS-like devices (proprietary, manufacturer-specific implementations). The radio interfaces of the sensor devices 3 have a limited, relatively short range, which, however, regularly extends at least to the nearest staircase 4, 5, 6.

Several transmission modules 7, 8, 9, 10, 11 according to the invention are installed in the stairwells 4, 5, 6, in particular on different floors or between the floors, so that the measurement data of all sensor devices are transmitted by the transmission modules 7, 8, 9, 10, 11 3 can be detected with radio interface. In addition, the transmission modules 7, 8, 9, 10, 11 are installed at such distances from one another that at least each transmission module 7, 8, 9, 10, 11 communicates with a neighboring transmission module 7, 8, 9, 10, 11 via its second radio interface can, possibly also with several adjacent transmission module. The transmission modules 7, 8, 9, 10, 11 automatically form a self-organizing mesh radio network via their respective second radio interface.

It can also be seen that the transmission module 11 is connected to the Internet 12 via a third interface, e.g. via an Ethernet interface.

Each transmission module 7, 8, 9, 10, 11 wirelessly records the measurement data from the group of sensor devices 3 assigned to it by means of its first radio interface using the measurement data transmission protocol. Each transmission module 7, 8, 9, 10, 11 uses its second radio interface to transmit the measurement data directly or indirectly via one or more further transmission modules 7, 8, 9, 10, 11 via the mesh radio network to the transmission module 11 connected to the Internet 12 The transmission module 11 connected to the Internet 12 transmits the measurement data to a server connected to the Internet 11 via its Internet connection. the 1 shows here by way of example that the measurement data recorded by the transmission module 9 are transmitted further via the transmission module 10 and other transmission modules up to the transmission module 11 .

the 2 makes it clear that the measurement data reach the server 13 via the Internet 11 , where they are decrypted and included in a measurement data database 14 . The measurement data contained in the database 14 can then be queried by data users 15, e.g. via a computer connected directly to the server 13 or via a data network, possibly also via the Internet 12.

the 3 shows highly schematized the structure of a transmission module using the example of the transmission module 7. The transmission module 7 has a first radio interface 30, a second radio interface 31, a third interface 32, a computer 33, a memory 34, a preprocessor 35, a first antenna 36, a second antenna 37, an air sensor 38, a power pack 39 and an update connection 40.

The components of the transmission module 7 mentioned can, for example, be arranged entirely or partially on a printed circuit board. The components instruct the necessary connections between each other the up. For example, the computer 33 is connected to the memory 34 . A computer program to which the computer 33 has access is stored in the memory 34 . The computer 33 executes at least parts of the computer program. The computer 33 also has access to the first radio interface 30, the second radio interface 31 and the third interface 32, optionally via the preprocessor 35. The transmission module 7 can be connected to the Internet 12 via the third interface 32.

The first radio interface 30 can be designed as a radio module, for example. The first radio interface 30 is connected to the first antenna 36, which can be designed as an OMS antenna, for example. The second radio interface 31 is connected to the second antenna 37, which can be in the form of a WiFi antenna (2.4 GHz), for example. The air sensor 38 can detect various physical parameters of the ambient air, such as temperature, humidity and pressure. For example, a corresponding air sensor module can be used for this. The update connection 40 allows access to the transmission module 7, e.g. for service purposes, for example for installing new firmware or for setting parameters.
