What problem did you solve?
We are currently involved in a project where we need to collect fuel consumption data on heavy duty vehicles. These vehicles should be BS6 compliant (equivalent of Euro6). It is difficult and expensive to install external fuel consumption measurement devices. Further, fleet owners are reluctant to allow retro-fitting such external devices. For this reason we preferred to log the fuel data via CAN instead.
How did you solve it?
We installed CANedge2 CAN loggers to capture data from the vehicle CAN bus. We bought and quickly configured the CANedge devices based on the documentation and prompt technical support provided by CSS. We also purchased a 4G WiFi router for use with the CANedge devices. The router is a handy accessory which allows the CANedge2 to directly upload data to our own cloud server. The raw MF4 log files from the loggers are post processed in MATLAB with the help of the software integration API provided by CSS. In MATLAB we then carried out different analyses on vehicle fuel consumption.
"The CANedge2 + CANmod.gps are the perfect combination for any telemetry project"
What benefit has this led to?
The CANedge2 has saved lot of time and human effort. These are essentially plug and play devices that are easy to install and configure. There are plenty of open-source software libraries provided by CSS (python, MATLAB) that can be used to process the raw data from CAN devices.
Why did you choose the CANedge2?
Before purchasing any CAN logging devices we had 2 requirements: Remote monitoring of CAN data and the ability to log both GPS and vehicle ECU data in a time synced manner. Both these requirements are fulfilled by the CANedge2 + CANmod.gps. We can remotely upload data to our cloud server using the 4G router. The uploaded data can be downloaded off our server from anywhere.
