Nachfolgend ist die Erfindung näher beschrieben.The invention is described in more detail below.
Die Erfindung betrifft die Kombination aus einem robustem Ultraschall-Ganzmetallsensor, kapazitiven Sensor und LPWAN-Funkeinheit (z. B. io-key FA. ifm electronic) zur Übertragung der Informationen (Füllstand und ggf. Alarm einer Leckage) in die Cloud.The invention relates to the combination of a robust ultrasonic all-metal sensor, capacitive sensor and LPWAN radio unit (e.g. io-key FA. ifm electronic) for the transmission of information (fill level and, if necessary, a leakage alarm) to the cloud.
Intermediate bulk Container (IBC) können unterschiedlichste Medien beinhalten und finden beispielsweise in der Industrie zahlreich Anwendung. Eine Füllstandsüberwachung dieser Container geschieht heute noch größtenteils mittels manueller, visueller Inspektionen. Aufgrund der Standardisierung von IBC Container, handelt es sich bei den Verschlusskappen um genormte Varianten, die beispielsweise durch Deckel mit einer Montagemöglichkeit für die Ultraschallsensoren ersetzt werden können.Intermediate bulk containers (IBC) can contain a wide variety of media and are used in many areas, for example in industry. Level monitoring of these containers is still largely done today by means of manual, visual inspections. Due to the standardization of IBC containers, the sealing caps are standardized variants that can be replaced, for example, by covers with a mounting option for the ultrasonic sensors.
Für die frühzeitige Erkennung eines baldigen Unterschreitens eines Mindestfüllstandes sowie zur Routenplanung einer effizienten Befüllung, bedarf es einer kontinuierlichen Füllstandsmessung. Aufgrund der Gegebenheit, dass sich die Container meist verteilt in Werkshallen/auf Werksgeländen befinden, ist eine Dateninfrastruktur nicht immer gegeben, weshalb eine Funktechnologie die ideale Lösung für den Datentransport darstellt.Continuous level measurement is required for early detection of soon falling below a minimum level and for route planning for efficient filling. Due to the fact that the containers are mostly distributed in factory halls/on factory premises, a data infrastructure is not always available, which is why radio technology is the ideal solution for data transport.
Zu Überwachung eignet sich ein Ultraschall-Ganzmetallsensor (die Vielfältigkeit der Medien bedarf den Einsatz eines Sensors, der eine hohe Resistenz gegenüber unterschiedlichen Medien aufweist) in Kombination mit einem io-key und der LPWAN (Low Power Wide Area Network) Funktechnologie NB-IoT (zellulare Mobilfunktechnologie Narrowband-loT). Neben der Füllstandsüberwachung kann es durchaus von Interesse sein, ob eine Leckage vorhanden ist. Hierzu kann ebenfalls ein unter dem Container befindlicher kapazitiver Sensor mit dem io-key verbunden werden, der Leckagen frühzeitig erkennt und als Warnung an einen zuvor definierten Empfängerkreis weiterleitet (Einschränkung des Leckage-Sensors: Nur Indoor).An ultrasonic all-metal sensor is suitable for monitoring (the variety of media requires the use of a sensor that has a high resistance to different media) in combination with an io-key and the LPWAN (Low Power Wide Area Network) wireless technology NB-IoT ( cellular mobile radio technology Narrowband-loT). In addition to level monitoring, it can also be of interest whether there is a leak. For this purpose, a capacitive sensor located under the container can also be connected to the io-key, which detects leaks at an early stage and forwards them as a warning to a previously defined group of recipients (restriction of the leak sensor: only indoors).
