Building an ISOBlue in Belgium

[Rik Claessens]

Hello I’m a student from Belgium and am currently studying at University.

My study is specialized in agricultural mechanization and i'm really interested in the concept of ISOBlue. I would like to build one. But have a few question since I am not the most experienced with programming software (I have some experience with arduino but want to take my acknowledge to a whole new level with this ISOBlue project).

I would like to know what’s the easiest way to read the data from the tractor, so it doesn’t has to be wireless yet it would be very handy.

My second question is how do I transfer the data I read from the isobus to understandable information.

I hope you guys can help me a little bit so I can start testing with the concept and introduce this interesting project to my University in Belgium.

Hello Rik,

Thank you for your interest in ISOBlue!

I would like to know what’s the easiest way to read the data from the tractor, so it doesn’t has to be wireless yet it would be very handy.

There are two ways: the ISOBlue way and the other is the non-ISOBlue way.

The ISOBlue way requires some work and it would definitely sharpen up your embedded Linux skills once you build one. To build one, please checkout isoblue.org, the corresponding Bills of Materials (BOM), and the build instructions (the instructions need improvement but let me know if you have questions. I will make revisions soon but the overall stays the same.). If you don't need wireless capabilities, just don't buy the cell module and don't worry about setting up the cell data plan. One feature of ISOBlue 2.0 is to collect all the data locally and push the data to the Cloud while it has an Internet connection.  So without a network connection, ISOBlue 2.0 will still collect all the machine data given the needed software are running correctly.

If you want a quick test to get some hands-on experience on collecting the data, you can do the non-ISOBlue way: build a ISOBUS diagnostic cable (it is also included in our BOM) to connect to a USB2CAN module. Connect the module to your laptop and write a script to read data from the machine of your interest. This is just an example. You can buy and use any other commercial hardware tools collect the data.

My second question is how do I transfer the data I read from the isobus to understandable information.

The essential piece in ISOBUS messages to decipher data is Parameter Group Numbers (PGNs). You will use this number to parse the data payload. To understand how these work, you will need the ISOBUS documentations. The standard we are interested in is called ISO11783.

Let me know if that helps.

Regards,

Yang

Hello Yang,

Thank you for your quick respons. I let you know if there are any further questions.

I hope that i have it running within a couple months.

Regards,

Rik
