Datenübermittlung per LED für industrielle Netzwerkgeräte Data transmission via LED for industrial network devices
Die Erfindung betrifft ein Verfahren zum Betreiben eines in einem Netzwerk betriebenen elektronischen Gerätes an ein Lesegerät, wobei das Gerät eine Betriebsanzeige aufweist, die einem Benutzer den Betrieb des Gerätes mittels sichtbarem Licht anzeigt, gemäß den Merkmalen des Oberbegriffes des Patentanspruches 1. The invention relates to a method for operating a network-operated electronic device to a reading device, wherein the device has a power indicator that indicates to a user the operation of the device by means of visible light, according to the features of the preamble of claim 1.
Jedes Gerät im Netz/Internet besitzt eine IP-Adresse, über die mit dem Gerät kommuniziert und über die das Gerät verwaltet werden kann. Diese IP-Adressen werden in vielen Fällen dynamisch zugewiesen oder sind zumindest vom Benutzer zugewiesen (aber trotzdem variabel). Viele Geräte besitzen keine Anzeige für die IP- Adresse, so dass ein Benutzer dem Gerät nicht ansehen kann, welche IP-Adresse zur Kommunikation verwendet werden muss. Dies wird in Zukunft insbesondere auf Geräte des loT (wie zum Beispiel Kühlschrank, Kaffeemaschine, Babyphone, loT: Internet of the things) zutreffen, da deren Internetfähigkeit bisher lediglich ein Nebenaspekt ihrer Funktion darstellt und das Design sich nach anderen Kriterien richtet. Each device in the network / Internet has an IP address that communicates with the device and through which the device can be managed. These IP addresses are often assigned dynamically or are at least user-assigned (but still variable). Many devices do not have an IP address indicator, so a user can not see what IP address to use for communication. In the future, this will apply in particular to devices of the laptop (such as, for example, a refrigerator, coffee machine, baby monitor, Internet of the things), since their Internet capability hitherto only represents a secondary aspect of their function and the design is based on other criteria.
Hieraus entsteht die Problematik, dass ein Netzwerkadministrator, der ein Problem im Netz anhand der IP-Adresse erkennt, dieses Gerät unter Umständen vor Ort nicht identifizieren kann und dass umgekehrt ein Benutzer vor dem Gerät dessen IP- Adresse nicht herausfinden kann. Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zum Betreiben eines elektronischen Gerätes bereitzustellen, mit dem das Gerät einfach und schnell identifiziert werden kann. This results in the problem that a network administrator who detects a problem in the network based on the IP address may not be able to identify this device in the field and that, conversely, a user in front of the device can not find out his IP address. The invention is therefore based on the object to provide a method for operating an electronic device with which the device can be easily and quickly identified.
Diese Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst. This object is solved by the features of claim 1.
Erfindungsgemäß ist vorgesehen, dass mittels der Betriebsanzeige eine Übermittlung von Identifikationsdaten erfolgt, wobei die übermittelten Identifikationsdaten von dem Lesegerät erfasst und ausgewertet werden. According to the invention, there is provided by means of the operating display a transmission of identification data, wherein the transmitted identification data are detected and evaluated by the reading device.
Um dieses Problem (Aufgabe) lösen zu können, Kosten am Gerät zu sparen und Freiheiten beim Design zu haben, hat sich überraschend herausgestellt, vorhandene Betriebsanzeigen, die mit sichtbarem Licht arbeiten (insbesondere gemäß einer Weiterbildung der Erfindung LEDs, zum Beispiel Power LED), eines Gerätes zu verwenden, um durch Modulation des Lichtes Identifikationsdaten (zum Beispiel die IP-Adresse) zu übertragen. Mittels der schon vorhandenen, preiswerten Betriebsanzeige wird somit nicht nur ein Betriebszustand des Gerätes (wie zum Beispiel EIN oder AUS oder Standby) angezeigt, sondern diese Betriebsanzeige wird auch für die Datenübertragung genutzt, um Identifikationsdaten des Gerätes auszusenden. In order to be able to solve this problem, to save costs on the device and to have design freedom, it has surprisingly been found that existing operating displays which work with visible light (in particular according to an embodiment of the invention LEDs, for example power LED), a device to transmit by identification of the light identification data (for example, the IP address). By means of the already existing, inexpensive operating display, not only an operating state of the device (such as, for example, ON or OFF or standby) is displayed, but this operating display is also used for data transmission in order to transmit identification data of the device.
Um auch auf der Empfängerseite Kosten zu sparen und eine universelle Verwendbarkeit zu garantieren, soll gemäß einer Weiterbildung der Erfindung als Empfänger ein Mobilgerät (zum Beispiel ein Handy, auch Smartphone genannt) mit Kamera verwendet werden. Dieses Mobilgerät analysiert in Echtzeit die Bilder der Kamera und interpretiert die Lichtmodulation als Daten, nämlich als Identifikationsdaten des Gerätes. Die Anwendung erfolgt ähnlich wie beim Einlesen eine QR-Codes oder bei der TAN-Generierung. Das sendende Gerät wiederholt gemäß einer Ausgestaltung der Erfindung die Nachricht mit seinen LEDs entweder zyklisch oder wird gemäß einer ergänzenden oder alternativen Ausgestaltung der Erfindung durch bestimmte Benutzeraktionen (zum Beispiel Kühlschranktür öffnen, schütteln...), die mit seinen (das heißt im Gerät) vorhandenen Sensoren erkannt werden können, zur Datenübertragung veranlasst. Besitzt das Gerät mehrere, nahe beieinanderliegende LEDs, kann die Datenübertragung parallelisiert werden, um eine höhere Datenrate zu erreichen. In order to save costs on the receiver side and to guarantee a universal usability, a mobile device (for example a mobile phone, also called a smartphone) with a camera is to be used as the receiver according to a development of the invention. This mobile device analyzes the images of the camera in real time and interprets the light modulation as data, namely as identification data of the device. The application is similar to reading a QR code or TAN generation. According to one embodiment of the invention, the sending device either cyclically repeats the message with its LEDs or, according to a supplementary or alternative embodiment of the invention, will open it by certain user actions (for example refrigerator door, shake ...) with its (ie in the device) existing sensors can be detected, causes data transmission. If the device has several, closely spaced LEDs, the data transmission can be parallelized to achieve a higher data rate.
Das Datenübertragungsprotokoll soll sich den Gegebenheiten des Gerätes anpassen können (Anzahl von LEDs, verschiedene Farben) und die jeweils beste Datenrate liefern. Die Übertragung muss jedoch mit einer einzigen einfarbigen LED auskommen können. The data transfer protocol should be able to adapt to the circumstances of the device (number of LEDs, different colors) and deliver the best data rate. However, the transmission must be able to manage with a single single-color LED.
Zur Absicherung der Datenübertragung werden Fehlererkennungs- und -korrekturalgorithmen verwendet. Diese Fehlererkennungsund -korrekturalgorithmen sind vorzugsweise standardisiert und entsprechend in dem Gerät sowie dem Lesegerät abgespeichert und werden während des Aussendens der Identifikationsdaten sowie deren Auswertung angewendet. To secure the data transmission error detection and correction algorithms are used. These error detection and correction algorithms are preferably standardized and stored accordingly in the device and the reader and are used during the transmission of the identification data and their evaluation.
Die Lösung betrifft somit die Übermittlung bestimmter Informationen hinsichtlich der Konfiguration von Netzwerkgeräten wie insbesondere Switches per LED an mobile Geräte (Lesegeräte) wie zum Beispiel Mobiltelefone, Tablets und dergleichen. The solution thus relates to the transmission of certain information regarding the configuration of network devices such as, in particular, switches via LED to mobile devices (readers) such as mobile phones, tablets and the like.
Insbesondere geht es um: In particular, it's about:
• Nutzung von ohnehin vorhandenen LEDs (zum Beispiel Power) zur Datenübertragung (im Gegensatz zu dedizierten LEDs zum Beispiel bei Infrarotschnittstellen) • Use of already existing LEDs (for example Power) for data transmission (in contrast to dedicated LEDs, for example with infrared interfaces)
• Übertragung von Identifikations- oder Managementdaten über existierende LEDs bei beliebigen Geräten im foT • Transmission of identification or management data via existing LEDs on any device in the fet
• ein Algorithmus, der in Abhängigkeit von Anzahl und Farbfähigkeiten der LEDs eine maximale Bandbreite liefert, der aber bereits mit einer einfarbigen LED funktioniert • ein besonders effektiver Bilderkennungsalgorithmus, der die Zustände/Farben der LEDs in den Kamerabildern erkennt • An algorithm that provides maximum bandwidth depending on the number and color capabilities of the LEDs, but which already works with a single-color LED • A particularly effective image recognition algorithm that detects the states / colors of the LEDs in the camera images
• Datenübertragung mittels sichtbarem Licht bei Netzwerkgeräten, insbesondere Industriegeräten • Data transmission by means of visible light in network devices, in particular industrial devices
