Research and Design on Vehicle-Mounted Wireless Transmission Terminal

Based on the wireless data transmission technologies, the vehicle-mounted wireless transmission terminal is able to provide reliable, up-to-date and accurate transport information for the moving vehicle, which contributes towards efficient road use, better traffic flow and greater road safety. The design of this vehicle-mounted wireless transmission terminal is based on ARM embedded technology and GPRS wireless transmission technology. By adopting S3C2440 as its microprocessor, this terminal connects with GPRS at first through driving GPRS communication module GTM900B, and then access to Internet by GPRS to transmit information or date from GPS and CAN. Experimental results show that the system has a strong practicality in data transmission, and it has an important practical value for the design of the vehicle monitoring system.
