A kind of monitoring and analysis system for freight vehicles

The safety of freight vehicles is a very important issue of our society, especially in the scope of VSNs(Vehicle Sensor networks). A monitoring and analysis system for freight vehicles is designed in this paper so as to achieve active safety and state records of freight vehicles. To lower costs and shorten development cycle, open-source electronics platform Arduino is selected as the main controller of the system. Sensors, communication modules and data storage modules are integrated in this system for data acquisition, transmission and record. Moreover, in order to facilitate data analysis, MATLAB is used to communicate with Arduino through serial port and corresponding MATLAB program is developed to get data from Arduino and analysis in real time. Experiment results show that the system can not only monitor the status of the freight vehicles, but also can be used as analysis tool of the status.
