Description

DK 2021 70096 A1 -1- Kommunikationsstruktur til transmission af information Den foreliggende opfindelse angår en kommunikationsstruktur til transmission af information ifølge den indledende del af krav 1 og en fremgangsmåde til trans- mission af information mellem flere måleenheder og en central computerindret- ning. Teknologisk baggrund Intelligente forbrugsmåleapparater, også kaldet Smart Meter, er forbrugsmåleap- parater, f.eks. til energi, strøm, gas, vand, der befinder sig i et forsyningsnet, og som viser den pågældende tilslutningsbruger det faktiske forbrug og er integreret i et kommunikationsnetværk. Intelligente forbrugsmåleapparater har den fordel, at manuelle aflæsninger af målerstandene bortfalder, og der på forsyningssiden kan — foretages kortfristede faktureringer i henhold til det faktiske forbrug. | kraft af kort- fristede aflæsningsintervaller er en mere nøjagtig kobling af slutkundetaksterne til udviklingen af børsstrømpriserne igen mulig. Forsyningsnettene kan også udnyt- tes væsentligt bedre.The present invention relates to a communication structure for transmitting information according to the preamble of claim 1 and a method for transmitting information between several measuring units and a central computer device. Technological background Intelligent consumption measuring devices, also called Smart Meters, are consumption measuring devices, e.g. for energy, electricity, gas, water located in a supply network, which shows the connection user in question the actual consumption and is integrated in a communication network. Intelligent consumption meters have the advantage that manual readings of the meter readings are eliminated, and on the supply side, short-term invoicing can be made according to the actual consumption. | Due to short-term reading intervals, a more accurate link of end-customer rates to the development of stock exchange prices is again possible. The supply networks can also be utilized significantly better.

— Intelligente forbrugsmåleapparater er sædvanligvis hver især tilordnet boligenhe- der eller beboelseshuse. De dér fremkommende måledata eller forbrugsdata kan udlæses på flere forskellige måder. Måledata kan f.eks. udlæses via strømnettet (Power Line). Endvidere kan måledata transmitteres i form af datapakker eller te- legrammer også pr. radio, f.eks. i ISM (Industrial, Scientific, Medical)-bånd-fre- — kvensområdet. Disse frekvensområder har den fordel, at kun en generel tilladelse af frekvensforvaltningen er nødvendig fra udbyderne.- Intelligent consumption measuring devices are usually each assigned to residential units or residential houses. The resulting measurement data or consumption data can be read out in several different ways. Measurement data can e.g. read out via the mains (Power Line). Furthermore, measurement data can be transmitted in the form of data packets or telegrams also per radio, e.g. in the ISM (Industrial, Scientific, Medical) band-frequency range. These frequency ranges have the advantage that only a general permission of the frequency management is required from the providers.

Indsamling af måledata pr. radio sker enten ved hjælp af stationære eller mobile dataindsamlingsindretninger eller datasamlere, som forbrugsdataene, der be- m— stemmes af forbrugsmåleapparaterne, transmitteres til. Datasamlerne koncentre- rer herved dataene (datakoncentratorer) eller gemmer disse og sender dem efter- følgende til en overordnet centralenhed (Head End), såsom f.eks. en central computerindretning eller en IT-struktur i leverandørens fordelingscentral, hvor deCollection of measurement data per. radio takes place either by means of stationary or mobile data collection devices or data collectors to which the consumption data determined by the consumption measuring devices is transmitted. The data collectors thereby concentrate the data (data concentrators) or store these and subsequently send them to a superior central unit (Head End), such as e.g. a central computer device or an IT structure in the supplier's distribution center, where they

DK 2021 70096 A1 -2- viderebearbejdes til f.eks. fakturering. Ved datatransmissionen mellem datasam- lerne og centralenheden er der som regel tale om en såkaldt vidtspændende kommunikation eller tertiær kommunikation, der anvender en bestemt kommuni- kationsprotokol og et tilsvarende dataformat til datatransmission.DK 2021 70096 A1 -2- is further processed to e.g. invoicing. The data transmission between the data collectors and the central unit is usually a so-called wide-ranging communication or tertiary communication, which uses a specific communication protocol and a corresponding data format for data transmission.

Trykskriftlig kendt teknik | DE 10 2014 102 007 B4 beskrives en fremgangsmåde til transmission af data, hvor terminaler transmitterer dataene ved hjælp af datafjerntransmission til en da- — tasamler. Datasamleren transmitterer igen dataene ved hjælp af datafjerntrans- mission til en kommunikationsenhed af en central computerindretning. Til dette er der tilvejebragt en central datahukommelse, som datasamleren kan lagre beske- derne på. Som transmissionsprotokol mellem datasamleren og computerindret- ningen anvendes der eksempelvis en FT-protokol (FTP; File Transfer Protocol), — hvor beskederne lagres på en FTP-server eller en cloud-server. Denne frem- gangsmåde har den ulempe, at yderligere datasamlere, der anvender en anden kommunikationsprotokol, kun kan transmittere data til computerindretningen ved hjælp af yderligere foranstaltninger. Der kan til implementering af den anden kommunikationsprotokol f.eks. installeres en yderligere kommunikationsenhed — som yderligere foranstaltning, der følgelig har en egen datahukommelse og en egen styreindretning. Disse foranstaltninger kan kun udføres tids- og omkost- ningskrævende, således at en sådan tilslutning kun kan muliggøres med tilsva- rende ulemper. Desuden medfører yderligere kommunikationsenheder yderligere tids- og omkostningsintensivt vedligeholdelses- og installationsarbejde.Printed known technique | DE 10 2014 102 007 B4 describes a method for transmitting data, in which terminals transmit the data by means of data remote transmission to a data collector. The data collector again transmits the data by means of data remote transmission to a communication unit of a central computer device. For this, a central data memory is provided, on which the data collector can store the messages. The transmission protocol between the data collector and the computer device uses, for example, an FT (File Transfer Protocol), where the messages are stored on an FTP server or a cloud server. This method has the disadvantage that additional data collectors using a different communication protocol can only transmit data to the computer device by means of additional measures. For the implementation of the second communication protocol, e.g. an additional communication unit is installed - as an additional measure, which consequently has its own data memory and its own control device. These measures can only be carried out in a time-consuming and costly manner, so that such a connection can only be made possible with corresponding disadvantages. In addition, additional communication devices involve additional time and cost intensive maintenance and installation work.

— Formålet med den foreliggende opfindelse Formålet med den foreliggende opfindelse består i at stile en kommunikations- struktur til rådighed, der sikkert og billigt muliggør en informationstransmission via forskellige kommunikationsprotokoller på nem måde.The object of the present invention The object of the present invention is to provide a communication structure which enables secure and inexpensive information transmission via various communication protocols in an easy manner.

DK 2021 70096 A1 -3- Opfyldelse af formålet Det foreliggende formål opfyldes ved hele læren fra krav 1 og det sideordnede — krav.DK 2021 70096 A1 -3- Fulfillment of the purpose The present purpose is fulfilled by the whole doctrine from claim 1 and the parallel - requirement.

Hensigtsmæssige udførelsesformer af opfindelsen er gjort gældende ifølge underkravene.Suitable embodiments of the invention are claimed according to the subclaims.

Ved opfindelsen kan forskellige datasamlere med forskellige kommunikationspro- tokoller tilsluttes til kommunikationsenheden.With the invention, different data collectors with different communication protocols can be connected to the communication unit.

En overordnet central computerind- — retning kræver f.eks. kun en grænseflade til modtagelse af dataene, dvs. skal kun understøtte en kommunikationsprotokol.An overall central computer device requires e.g. only one interface for receiving the data, i.e. should only support one communication protocol.

Informationstransmissionen forenkles dermed betragteligt.The information transmission is thus considerably simplified.

På fordelagtig måde kan f.eks. datasamlere derved fornys trinvist, idet også ældre datasamlere, der f.eks. stadig kommunikerer via en æl- dre kommunikationsprotokol, kan transmittere information til de centrale compu- — terindretninger.Advantageously, e.g. data collectors are thereby renewed step by step, as also older data collectors who e.g. still communicates via an older communication protocol, can transmit information to the central computer devices.

Den centrale computerindretning skal herved ikke understøtte den ældre kommunikationsprotokol.The central computer device must not support the older communication protocol.

Fortrinsvis anvendes der som anden kommunikationsprotokol en MQTT (Mes- sage Queue Telemetry Transport) -protokol.Preferably, an MQTT (Message Queue Telemetry Transport) protocol is used as the second communication protocol.

Herved er der både omfattet MQTT- — specifikationer, der er TCP/IP-baseret eller ikke er TCP/IP-baseret (såsom f.eks.This includes both MQTT specifications that are TCP / IP based or not TCP / IP based (such as e.g.

MQTT-SN). Tilsvarende kan der ved datafordelerenheden fortrinsvis være tale om en MQTT-broker, der er ansvarlig for fordeling og tilordning af dataene og for- trinsvis arbejder i henhold til Publish/Subscribe-fremgangsmåden.MQTT-SN). Similarly, the data distributor unit may preferably be an MQTT broker who is responsible for the distribution and assignment of the data and preferably works in accordance with the Publish / Subscribe procedure.

Ved anven- delse af MQTT-protokollen sammen med en yderligere protokol kan sikkerheden — ved informationstransmissionen forøges i særlig grad.By using the MQTT protocol together with an additional protocol, the security of the information transmission can be increased to a special degree.

Hensigtsmæssigt kan der ved datagrænsefladen være tale om en web-, cloud- eller filserver.Conveniently, the data interface may be a web, cloud or file server.

Fortrinsvis er der tale om en FTP-server, der stiller et filsystem eller mindst en del af et filsystem til rådighed, dvs. eksempelvis omfatter en datahu- — kommelse (f.eks. en harddisk) med filorganisering.Preferably, it is an FTP server that provides a file system or at least part of a file system, i.e. for example, includes a data memory (such as a hard disk) with file organization.

Ved anvendelse af en sådan filserver kan der endvidere ske en kontrol af adgangsrettighederne, f.eks. ved hjælp af filserveren selv eller en berettigelsesforespørgsel i filsystemet.When using such a file server, the access rights can also be checked, e.g. using the file server itself or a justification request in the file system.

DK 2021 70096 A1 - 4- I henhold til en foretrukket udførelsesform af opfindelsen omfatter datasamleren og den centrale computerindretning hver især kun en grænseflade og en kommu- nikationsprotokol til transmission af dataene. På den måde kan datasamlerens og/eller den centrale computerindretnings opbygning forenkles betydeligt. Desu- den kan transmissionen af information i hele kommunikationssystemet med hen- syn til transmissionsmåde og transmissionsstandard i det væsentlige standardi- seres. Endvidere er der tilvejebragt transmissionsmidler, der muliggør trådløs og/eller — trådbundet transmission mellem kommunikationsenheden og den centrale com- puterindretning. Ved transmissionsmidlet kan der f.eks. også være tale om en sende- og modtageindretning eller en ledningstilslutning (f.eks. Powerline). Transmissionen af data mellem kommunikationsenheden og datasamleren og/el- ler den centrale computerindretning sker fortrinsvis via en sikret datakanal, især via en ende-til-ende-krypteret datakanal.DK 2021 70096 A1 - 4- According to a preferred embodiment of the invention, the data collector and the central computer device each comprise only an interface and a communication protocol for transmitting the data. In this way, the structure of the data collector and / or the central computer device can be considerably simplified. In addition, the transmission of information throughout the communication system can be substantially standardized in terms of transmission mode and transmission standard. Furthermore, transmission means are provided which enable wireless and / or wired transmission between the communication unit and the central computer device. With the transmission means, e.g. also be a transmitting and receiving device or a cable connection (eg Powerline). The transmission of data between the communication unit and the data collector and / or the central computer device preferably takes place via a secured data channel, in particular via an end-to-end encrypted data channel.

Datafordelerenheden kan til transmission af informationen hensigtsmæssigt kræve en autentificering fra en client såsom datasamleren, f.eks. ved hjælp af en — gyldig brugernavn/password-kombination, som datasamleren skal bruge eller sende ved etablering af forbindelsen med kommunikationsenheden for at kunne udføre en transmission af dataene. Datatransmissionens og dataintegritetens sik- kerhed forbedres derved betydeligt.For the transmission of the information, the data distributor unit may suitably require an authentication from a client such as the data collector, e.g. using a - valid username / password combination that the data collector must use or send when establishing the connection with the communication device in order to perform a transmission of the data. The security of data transmission and data integrity is thereby significantly improved.

Databroen er fortrinsvis udformet som softwareløsning, der adapterer den første og anden kommunikationsprotokols kommunikationsparametre. På den måde kan databroen på nem måde også implementeres eller opgraderes i eksisterende systemer, f.eks. ved en firmwareupdate eller lignende.The data bridge is preferably designed as a software solution that adapts the communication parameters of the first and second communication protocols. In this way, the data bridge can easily be implemented or upgraded in existing systems, e.g. by a firmware update or similar.

— Kommunikationsenheden kan endvidere være indrettet til at omdanne den første kommunikationsprotokol og/eller den anden kommunikationsprotokol og/eller yderligere kommunikationsprotokoller til en kommunikationsprotokol, der har en højere sikkerhed end den oprindelige kommunikationsprotokol. Desuden kan også data af det første dataformat og/eller det andet dataformat omdannes til etThe communication unit may further be arranged to convert the first communication protocol and / or the second communication protocol and / or additional communication protocols into a communication protocol having a higher security than the original communication protocol. In addition, data of the first data format and / or the second data format can also be converted into one

DK 2021 70096 A1 -5- dataformat, der har en højere sikkerhed end det oprindelige dataformat. Sikker- heden forbedres således yderligere. Eksempelvis kan data, der er transmitteret ved hjælp af en FT-protokol, derved omdannes til et SSH (Secure Shell)-datafor- mat og transmitteres ved hjælp af SSH-protokollen.DK 2021 70096 A1 -5 data format, which has a higher security than the original data format. Security is thus further improved. For example, data transmitted using an FT protocol can be converted to an SSH (Secure Shell) data format and transmitted using the SSH protocol.

Der kan hensigtsmæssigt være tilvejebragt mindst en yderligere datagrænse- flade, der er indrettet til at udføre transmission af dataene ved hjælp af en tredje kommunikationsprotokol. På den måde kan informationstransmissionen også ud- vides til yderligere kommunikationsprotokoller, hvorved kommunikationsenheden kan anvendes endnu mere fleksibelt.At least one additional data interface adapted to perform transmission of the data by means of a third communication protocol may conveniently be provided. In this way, the information transmission can also be extended to additional communication protocols, whereby the communication unit can be used even more flexibly.

Kommunikationsenheden kan i henhold til en særlig udførelsesform være indret- tet til valgfrit at understøtte en flerhed af kommunikationsprotokoller. Idet at der kan vælges mellem forskellige kommunikationsprotokoller, bliver tilslutning af — eksterne apparater, f.eks. datasamlere, endnu mere fleksibel. Der kan endvidere være tilvejebragt yderligere kommunikationsprotokoller (f.eks. en fjerde og femte kommunikationsprotokol).According to a special embodiment, the communication unit can be arranged to optionally support a plurality of communication protocols. Being able to choose between different communication protocols, the connection of - external devices, e.g. data collectors, even more flexible. In addition, additional communication protocols may be provided (e.g., a fourth and fifth communication protocol).

Ved kommunikationsenheden kan der hensigtsmæssigt være tale om en funkti- — onsenhed af den centrale computerindretning. Kommunikationsenheden kan f.eks. hardware- og/eller softwareteknisk være tilsluttet til eller integreret i den centrale computerindretning.The communication unit may suitably be a functional unit of the central computer device. The communication unit can e.g. hardware and / or software technology be connected to or integrated in the central computer device.

Fortrinsvis er der ved informationen tale om forbrugsdata, der er registreret af et — forbrugsmåleapparat, og som f.eks. transmitteres fra forbrugsmåleapparatet til centralenheden via datasamleren. Ved forbrugsmåleapparaterne kan der eksem- pelvis være tale om et Smart Meter til registrering af strøm-, vand-, gas- og/eller varmemængdeforbruget.Preferably, the information refers to consumption data, which is registered by a - consumption measuring device, and which e.g. transmitted from the consumption measuring device to the central unit via the data collector. The consumption measuring devices may, for example, be a Smart Meter for recording the electricity, water, gas and / or heat consumption.

Gjort gældende sideordnet med den foreliggende opfindelse er en fremgangs- måde til transmission af information mellem flere måleenheder, især forbrugsmå- leapparater til registrering af strøm-, vand-, gas- og/eller varmemængdeforbruget, og en central computerindretning. Ved fremgangsmåden transmitteres informatio- nen fra måleenheden til den centrale computerindretning og/eller fra den centraleApplied in parallel with the present invention is a method for transmitting information between several measuring units, in particular consumption measuring devices for recording the consumption of electricity, water, gas and / or heat quantity, and a central computer device. In the method, the information is transmitted from the measuring unit to the central computer device and / or from the central

Transmissionen af information mellem måleenheden og den centrale computerindretning sker herved via en kommunikationsstruktur ifølge opfindelsen, der omfatter en datafordelerenhed, der er indrettet til at udføre transmission af dataene i et andet dataformat, der er — forskelligt fra det første dataformat, ved hjælp af en anden kommunikationsproto- kol. Endvidere er der anbragt en databro mellem filsystemet og datafordelerenhe- den, der tjener til at importere data i det andet dataformat som data i det første dataformat til filsystemet og/eller eksportere data af det første dataformat som data af det andet dataformat fra filsystemet.DK 2021 70096 A1 - 6 - computer device for the measuring unit in the form of data. The transmission of information between the measuring unit and the central computer device hereby takes place via a communication structure according to the invention, which comprises a data distributor unit which is arranged to perform transmission of the data in a second data format which is - different from the first data format, by means of a second communication protocol. Furthermore, a data bridge is arranged between the file system and the data distributor unit, which serves to import data in the second data format as data in the first data format to the file system and / or export data of the first data format as data of the second data format from the file system.

Between the data collectors 101, 102, 103 and the central computer device 100, corresponding data interfaces 104, 105, 106 are arranged in each case, each of which comprises a file system 104a, 105a, 106a and a control device 104b, 105b, 106b. The communication system in FIG. 1 has i.a. the disadvantage that a large hard and soft

DK 2021 70096 A1 -7- wareomkostning er nødvendig til implementering af de forskellige kommunikati- onsprotokoller af de pågældende datasamlere 101, 102, 103. Endvidere skal den centrale computerindretning 100 understøtte alle anvendte kommunikationsproto- koller og adaptere de tilsvarende kommunikationsparametre af kommunikations- — protokollerne, dvs. omfatter egnede grænseflader for at sikre succesfuld informa- tionstransmission. I fig. 2 er der vist et kommunikationssystem, hvor der sker en informationstrans- mission mellem en central computerindretning 10 og flere måleenheder eller for- brugsmaleapparater 11-15. Ved forbrugsmåleapparaterne 11-15 kan der eksem- pelvis være tale om strøm-, vand-, gas- eller varmemængdetællere. Forbrugsmå- leapparaternes 11-15 aktuelle tællerstande transmitteres til computerenheden 10 i form af data eller forbrugsdata via en kommunikationsstruktur ifølge opfindelsen. Kommunikationsstrukturen omfatter til dette en kommunikationsenhed 1 og flere — datasamlere 7, 8 eller datakoncentratorer til at koncentrere og/eller (mellem- Jlagre dataene. Datatransmissionen mellem forbrugsmåleapparaterne 11-15 og datasamlerne 7, 8 kan ske valgfrit (f.eks. via radio) eller trådbundet (f.eks. via Po- werline).DK 2021 70096 A1 -7- ware cost is necessary for the implementation of the various communication protocols of the respective data collectors 101, 102, 103. Furthermore, the central computer device 100 must support all used communication protocols and adapt the corresponding communication parameters of the communication protocols. , i.e. include suitable interfaces to ensure successful information transmission. In FIG. 2 shows a communication system in which an information transmission takes place between a central computer device 10 and several measuring units or consumption measuring devices 11-15. The consumption measuring devices 11-15 may, for example, be electricity, water, gas or heat flow meters. The current counters of the consumption measuring devices 11-15 are transmitted to the computer unit 10 in the form of data or consumption data via a communication structure according to the invention. For this purpose, the communication structure comprises a communication unit 1 and more - data collectors 7, 8 or data concentrators for concentrating and / or (intermediate storage) the data. The data transmission between the consumption measuring devices 11-15 and the data collectors 7, 8 can take place optionally (eg via radio) or wired (eg via Powerline).

— Kommunikationsenheden 1 omfatter en datagrænseflade 2, der f.eks. er udfor- met som FTP-server (FTP-filserver). En FTP-protokol tjener herved som første kommunikationsprotokol til informationstransmission mellem datasamleren 7 og datagrænsefladen 2. Derudover er et filsystem 3 tilordnet til FTP-serveren, hvilket filsystem fungerer som infrastruktur og data- eller mellemlager. Datasamlerens 7 data kan således transmitteres fra datasamleren 7 til datagrænsefladen 2 i et før- ste dataformat, dvs. i dette tilfælde i et FTP-filformat, og efterfølgende gemmes i filsystemet 3.The communication unit 1 comprises a data interface 2 which e.g. is designed as an FTP server (FTP file server). An FTP protocol thereby serves as the first communication protocol for information transmission between the data collector 7 and the data interface 2. In addition, a file system 3 is assigned to the FTP server, which file system functions as an infrastructure and data or intermediate storage. The data of the data collector 7 can thus be transmitted from the data collector 7 to the data interface 2 in a first data format, i.e. in this case in an FTP file format, and subsequently saved in the file system 3.

Datatransmissionen mellem kommunikationsenheden 1 og den centrale compu- terindretning 10 sker via en datafordelerenhed 4, der er udformet som MQTT-bro- ker (MQTT-fordeler) ved udførelsesformen i fig. 2. Datasamlerens 8 data kan på nem måde transmitteres til datafordelerenheden 4 via den anden kommunikati- onsprotokol, en såkaldt MQTT-protokol, i et andet dataformat, dvs. som beskeder eller telemetridata i MQTT-dataformat. Disse data kan efterfølgende transmitteresThe data transmission between the communication unit 1 and the central computer device 10 takes place via a data distributor unit 4, which is designed as an MQTT broker (MQTT distributor) in the embodiment in fig. The data of the data collector 8 can easily be transmitted to the data distributor unit 4 via the second communication protocol, a so-called MQTT protocol, in a different data format, ie. as messages or telemetry data in MQTT data format. This data can subsequently be transmitted

DK 2021 70096 A1 - 8- fra datafordelerenheden 4 til den centrale computerindretning 10 eller først impor- teres til filsystemet 3 for at lagre disse. Kommunikationsenheden 1 omfatter til da- taimport en databro 5, der er anbragt mellem datagrænsefladen 2 og datafordele- renheden 4. Dataene kan herved importeres fra datafordelerenheden 4 til filsyste- met 3 via databroen 5. Databroen 5 omfatter til dette en konverteringsenhed 6, der er udformet som MQTT-client. Konverteringsenheden 6 konverterer dataene af det andet dataformat, dvs. MQTT-dataformatet, til data af det første dataformat og transmitterer disse til filsystemet 3.DK 2021 70096 A1 - 8- from the data distributor unit 4 to the central computer device 10 or first imported to the file system 3 to store these. For data import, the communication unit 1 comprises a data bridge 5, which is arranged between the data interface 2 and the data distribution unit 4. The data can hereby be imported from the data distribution unit 4 to the file system 3 via the data bridge 5. The data bridge 5 comprises a conversion unit 6 designed as an MQTT client. The conversion unit 6 converts the data of the second data format, i.e. The MQTT data format, for data of the first data format and transmits these to the file system 3.

— Dataene kan endvidere transmitteres eller eksporteres fra filsystemet 3 til datafor- delerenheden 4 via databroen 5, således at også filsystemets 3 data kan trans- mitteres til den centrale computerindretning 10 via datafordelerenheden 4 ved hjælp af den anden kommunikationsprotokol. Konverteringsenheden 6 kan der- ved konvertere dataene af det første dataformat (FTP-filformat), som befinder sig ifilsystemet 3, til data af det andet dataformat (MQTT-dataformat) og transmit- tere, dvs. eksportere, dem til datafordelerenheden 4.The data can furthermore be transmitted or exported from the file system 3 to the data distributor unit 4 via the data bridge 5, so that also the data of the file system 3 can be transmitted to the central computer device 10 via the data distributor unit 4 by means of the second communication protocol. The conversion unit 6 can thereby convert the data of the first data format (FTP file format), which is located in the file system 3, to data of the second data format (MQTT data format) and transmit, i.e. export them to the data distribution unit 4.

Datafordelerenhedens 4 centrale opgave består i at fordele eller tilordne dataene eller beskederne, således at f.eks. beskederne, der sendes fra datasamleren 8, — også når de tilsvarende modtagende enheder, såsom den centrale computerind- retning 10. Datafordelerenheden 4 kan på fordelagtig måde til dette omfatte en autentificeringsfunktion, idet der f.eks. kun accepteres en subscriber eller publi- sher, der anvender en gyldig password/brugernavn-kombination til transmission eller ved etablering af forbindelse til datafordelerenheden 4.The central task of the data distributor unit 4 consists of distributing or assigning the data or messages so that e.g. the messages sent from the data collector 8 also reach the corresponding receiving units, such as the central computer device 10. The data distributor unit 4 may advantageously comprise an authentication function for this, e.g. only a subscriber or publisher who uses a valid password / username combination for transmission or when establishing a connection to the data distributor unit is accepted 4.

De to kommunikationsprotokoller, f.eks. MQTT og FTP, kobles således via data- broen 5. Disse databroer 5 kan f.eks. være udformet som softwareløsning, der er anbragt mellem datafordelerenheden 4 (MQTT-broker) og datahukommelsen 3 (FTP-filserver). | kraft af konverteringsenhedens 6 (MQTT-client) import- og ek- sportfunktion kan der således skabes en bidirektional kommunikation mellem FTP og MQTT. På den måde kan der vilkårligt tilsluttes datasamlere 7, 8, selvom de kommunikerer via MQTT eller FTP.The two communication protocols, e.g. MQTT and FTP, are thus connected via the data bridge 5. These data bridges 5 can e.g. be designed as a software solution located between the data distribution unit 4 (MQTT broker) and the data memory 3 (FTP file server). | by virtue of the import and export function of the conversion unit 6 (MQTT client), a bidirectional communication between FTP and MQTT can thus be created. In this way, data collectors 7, 8 can be arbitrarily connected, even if they communicate via MQTT or FTP.

DK 2021 70096 A1 -9- Genstanden for den foreliggende opfindelse kan principielt også udvides til andre kommunikationsprotokoller. | henhold til en foretrukket udførelsesform kan der være tilvejebragt en tredje kommunikationsprotokol. Derved er der tale om en kommunikationsprotokol, der har en højere sikkerhed end den første og/eller an- den kommunikationsprotokol, såsom f.eks. SFTP (Simple File Transfer Protocol) eller SSH (Secure Shell). Kommunikationsenheden er hensigtsmæssigt indrettet til f eks. at omdanne den første og/eller den anden kommunikationsprotokol til en sådan sikker kommunikationsprotokol. Der kan f.eks. også være tilvejebragt en yderligere datagrænseflade 9, som vist i fig. 3, der muliggør datatransmission ved — hjælp af den tredje kommunikationsprotokol.DK 2021 70096 A1 -9- The subject matter of the present invention can in principle also be extended to other communication protocols. | according to a preferred embodiment, a third communication protocol may be provided. This is a communication protocol that has a higher security than the first and / or second communication protocol, such as e.g. SFTP (Simple File Transfer Protocol) or SSH (Secure Shell). The communication unit is suitably arranged to, for example, convert the first and / or the second communication protocol into such a secure communication protocol. For example. also be provided an additional data interface 9, as shown in fig. 3, which enables data transmission by means of the third communication protocol.

Alternativt eller yderligere kan der ud over de nævnte kommunikationsprotokoller (FTP, MQTT, SFTP, SSH) også være tilvejebragt andre kommunikationsprotokol- ler og dertilhørende dataformater. Der kan f.eks. også være tale om en WebDAV- — protokol og/eller SCP-protokol og/eller HTTP-protokol og/eller HTTPS-protokol og/eller SMTP-protokol og/eller POP3-protokol og/eller IMAP-protokol og/eller NTP-protokol og/eller SMB/CIFS-protokol og/eller NFS-protokol. Derudover kan der også anvendes yderligere kommunikationsprotokoller af anvendelseslaget (OSI-lag 5-7).Alternatively or additionally, in addition to the mentioned communication protocols (FTP, MQTT, SFTP, SSH), other communication protocols and associated data formats may also be provided. For example. also be a WebDAV protocol and / or SCP protocol and / or HTTP protocol and / or HTTPS protocol and / or SMTP protocol and / or POP3 protocol and / or IMAP protocol and / or NTP protocol and / or SMB / CIFS protocol and / or NFS protocol. In addition, additional communication protocols of the application layer (OSI layers 5-7) can also be used.

Via kommunikationsenheden 1 kan der hensigtsmæssigt også tilsluttes andre strukturelle enheder, såsom f.eks. en mobil udlæsningsindretning 16 (mobil data- samler) til drive-by- eller walk-by-aflæsning eller et analyseværktøj 17 f.eks. til ka- rakterisering af forbindelsen/transmissionen.Via the communication unit 1 it is expediently also possible to connect other structural units, such as e.g. a mobile readout device 16 (mobile data collector) for drive-by or walk-by reading or an analysis tool 17 e.g. to characterize the connection / transmission.
