CAN Tool for Atlas Copco’s Rig Control System

Sammanfattning: The goal of this 15 hp thesis in computer engineering was to develop a tool for monitoring and analyzing the data flow on a Controller Area Network (CAN) called Rig Control System (RCS) that is used by Atlas Copco. Atlas Copco develops and manufactures machines for Mining and Rock Excavation. The Rocktec division is responsible for the Rig Control System platform used on machines in all division within the Mining and Rock Excavation Technique (MR) business area. The tool’s primary purpose is monitor and analyze data from the RCS network and present the analyzed data in an easy way to help with development and maintenance of RCS and machines that use RCS. The advantages and how data is sent over the CAN bus are presented as well as the CANopen protocol which is a higher layer protocol based on CAN. Two ways of data acquisition from RCS are presented, a simulated environment and real hardware. Different types of interprocess communication are presented as well as the pros and cons of each of these types. The creation of the tool required a Graphical User Interface (GUI) so different frameworks for this task are also presented and discussed. A version of the tool is presented and discussed in detail. The result of the project is a tool that with further development can be of great use to developers and service engineers working with RCS.
