Тема: How to connect Eurosens DPS CAN axle load sensor to GPS tracker

Eurosens DPS CAN - new axle load sensor from Mechatronics with CAN BUS J1939 interface.

Each sensor supports up to 3 calibration tables  - when we have 3 axles supporting one air spring it is an advantage.
Each axle load value can be assigned with PGN.

By default - PGNs 59121, 59122, 59123 are used.  (E6F1, E6F2, E6F3 in Hex-format)


Add this PGN to read in GPS tracker settings (Navtelecom Smart 2435 is used), 2 calibration table - for 2 axles per 1 sensor.

Then add 2 sensors in Wialon based on incoming raw data:

Re: How to connect Eurosens DPS CAN axle load sensor to GPS tracker

Axle load come in kilograms, so calibration coefficients are not needed

Same settings for Eurosens DPS connection to Galileosky gps tracker

Galileo configurator has built-in scanner so we can see Eurosens DPS messages:

Galileo CAN Scanner

We can see that each message from sensor contains several parameters:
bytes 1-2 : internal raw sensor data
bytes 3-4 : pressure  in kPa
bytes 5-6 : axle load in kg

And we can assign desired parameters to protocol tags column

Then choose protocol tags to be sent to server
