A Real-Time Embedded System for Monitoring of Cargo Vehicles, Using Controller Area Network (CAN)

摘要

This paper presents the creation of a CAN network for monitoring parameters route of cargo vehicles. By decree of law, all cargo vehicles must contain tachograph device that collects and records all information practiced during the trip, such as speed, distance, RPM (rotations per minute), among other parameters. The data provided by the tachograph are sent to the CAN network, collected and interpreted by AT90CAN128 microcontroller and sent to the monitoring station by serial communication by a tracker (MTC 500). Thus, the central monitoring company will quickly follow the route of its drivers, and the characteristics of travel practiced by them.
