Data Acquisition / Network (1)
5th & 6th MARINe Electrical Ini4a4VE (MARINELIVE) Interna4onal Workshop on Ship Electric Grids and Power Management Systems
Data Acquisition / Network (2)
• The Black Box devices have ethernet ports (wired communication) • Converted to wireless using wifi-router • (the notebook computer connects wirelessly to the router, the black boxes are connected with ethernet cables)
5th & 6th MARINe Electrical Ini4a4VE (MARINELIVE) Interna4onal Workshop on Ship Electric Grids and Power Management Systems
Data Acquisition / Network (3) • A completely wireless solution was also developed, using micro-wifi routers (acting as wireless clients) • USB powered, 5x5cm footprint, can be powered by the Black Box (since it has a usb port) • Hybrid wired-wireless topologies can be used
