Abstract: In order to reduce the road transportation accidents of dangerous cargo, to improve the transport efficiency and protect the security of driver-vehicle-cargo during transportation, an intelligent vehicle terminal was designed for the safety of the transport of dangerous cargo independently. The intelligent vehicle terminal was responsible for the realtime monitoring of driving state, the running state of vehicles and dangerous cargo. The terminal also has functions such as communication, navigation and networking. Hardware includes navigation module, MEMS sensor module, microprocessor module, power module and so on. Software system is composed of lower computer software and PC software, the functions of lower computer software are system initialization, data acquisition and processing; the PC software is responsible for calling data from lower machine to display vehicle status, and complete interactions with the driver. Finally, a road test was carried out based on the designed terminal platform. The results indicate that the intelligent vehicle terminal can run stately and have good performance.
