Examples of the use of the embedded systems for the long-term collection of slowly-changing parameters in the traction of a car

Wołczyński Zbigniew

2021

R. 60, nr 4

106--112

The article presents how embedded systems can be used to collect data in the long-term traction of a car. It is assumed that the long period is the time of a travelled distance, e.g. a few thousands of kilometres, or a time, e.g. a month. Such data can be used to optimize the control systems and to diagnose unusual faults in mechatronic systems. The research paper presents how, with the use of very cheap devices, it is possible to collect data that quite often could not be collected even with the use of very expensive measuring devices. The possibility of simple analysis of signals in real time was also pointed out.

Response-time analysis of a CAN network used for supervisory control and diagnostic systems

Werewka J., Dach M.

Control and Cybernetics

2010

Vol. 39, no 4

1135-1157

This paper refers to construction methods of Supervisory Control and Diagnostic Systems (SCDS) based on a CAN bus. Emphasis is put on the construction of such systems. Meeting real time constraints has become one of major aspects of this elaboration. The study enumerates possibilities of using various communication mechanisms of CAN, applicable for real-time systems. Proposed solutions are especially suitable for general-purpose SCDS. Principles of real-time analysis for CAN bus based systems are discussed as well. An example of SCDS implementation for a Swiss Light Source (SLS) large scale accelerator project is given. Time analysis is made for the constructed system with real-time conditions met. Experiments performed in the SLS confirm the results of the analysis.
