Embedded System Design for Speed Measurement and Timing of Vehicles

摘要

Embedded system for speed measurement and time is designed by adopting sensor and computer control technology to monitor operation condi tion of vehicles in real time, measuring and recording the speed while running in the examining locale. According to the function target, the design scheme is put forward to carry out the design of photoelectric receiving, single chip sys tem, wireless communications circuit, and software realization. The mechanism is designed rationally, achieving the aim that unchanging vehicles and installing expediently.
