nemi EdgeBase

4G-Gateway with Linux Operating System and Edge Computing Capabilities

nemi EdgeBase forms the bridge between the sensor nodes in the wireless network nemi Link 2400 and worldwide networks. As a gateway, it receives the data from up to eight wireless sensor nodes or measures data itself through integrated MEMS and GPS technology. All data can be stored on an internal SSD drive. For data reduction, edge analytics based on Python scripts can be performed on nemi EdgeBase before data is transmitted over a secure 4G cellular connection or a wired network connection. The 4G-Gateway nemi EdgeBase is convincing in various use cases where long-term monitoring is carried out to perform predictive maintenance. This includes, for example, permanent data acquisition for load monitoring on wind turbines, condition monitoring of rolling bearings or the permanent monitoring of roller coaster ride performance.

Use Case

Ansicht einer Achterbahn zum Use Case "Online Monitoring zur Analyse des dynamischen Verhaltens von Achterbahnen"

Online condition monitoring for the analysis of the dynamic behavior of roller coasters

To enable continuous online condition monitoring, we installed a nemione measuring system on a roller coaster that provides reliable data with the help of three small wireless sensors (nemi G+ and nemi DAQ) and the gateway nemi EdgeBase.
