Bai Shun Su, Bao Ding Zhang · Applied Mechanics and Materials · 2013
On the analysis of the development situation of the ETC home and abroad, CC2431 wireless location function is used in the high speed highway ETC system to realize data transmission between network centre node and terminal node safely, Record passing information of the vehicle terminal by the wireless data transmission between the coordinator and vehicle terminal. A weighted centroid position algorithm is introduced to meet the position accuracy. The test results of the wireless communication between vehicle terminal and coordinator show that CC2431 wireless position system can realize vehicle omnibearing position and real time monitor in the super-speed highway.
