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

ABSTRACT:

This project 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.

In this project, we are measuring the speed of the vehicle and distance it was travelled. For this purpose we are using the hall sensor. The speed as well as the distance the vehicle covered was displayed on the LCD screen. All these details are send to the dashboard side by using the CAN protocol. Controller Area Network or CAN protocol is a method of communication between various electronic devices like engine management systems, active suspension, ABS, gear control, lighting control, air conditioning, airbags, central locking etc embedded in an automobile.

Besides these, we are using the alcohol sensor as well as ultrasonic sensor. The alcohol sensor is used to detect the consumption of the alcohol by the driver and stops the vehicle to prevent accidents due to alcohol consumption. And also send the alert message to the particular mobile number along with the GPS location values. The ultrasonic sensor is used to measure the distance from the leading vehicle and control the speed of the vehicle accordingly to avoid the collision. The sensor data was also transmitted to the dashboard side via CAN protocol. We are also incorporating the IoT also in our project by including the Wi-Fi module to the ARM cortex controller. All the parameters of the vehicles are sent to the web server by using the Wi-Fi module.
