A quick Proof-of-concept was needed to demonstrate web based Locomotive Fuel monitoring capability . Diesel based fuel sensor was a SICK sensor and hardware interface to it was built by third party. There was a need to build an internet gateway device to upload and display the fuel readings along with the GPS coordinates, speed, etc and the associated book keeping, etc. As this was a PoC, an Off-the-Shelf SBC with a 2G modem was chosen and quickly integrated to provide internet communication, reading from fuel sensor hardware, interfacing with GPS device and web server integration service to push all the relevant data. An nginx php web server was run on an AWS instance after the DNS procurement etc. Openstreet maps was used as it is free and simpler to use than others. An access token to access the OSM tiles/etc was obtained and Leaflet was used to customise and show the maps/tiles, customize markers, etc. As this was installed on only one locomotive, the pictur...
Teeny space in the WebVerse to shamelessly brag (document) about things that were attempted, things that worked and that did not, both in the professional and hobby fronts.

It might not work for you. Try at your own risk. Thank you for stopping by and would be delighted to hear from you.
