Multi-function intelligent instrument of vehicle detection based on embedded system

By analyzing all kinds of application situation about speed and sideslip test-bed, a multi-function intelligent instrument of speed and sideslip detection based on embedded system was designed. Its operation principle, hardware constitution and design method of system software was described. It has such functions as data acquisition, data processing, fault diagnosis and etc. This instrument suits to three kinds of sensor. It is fit for different applications, and the application results indicate that it is not only a low cost and highly universal detection instrument of speed and sideslip, but also the only kind of small-scale multi-function, instrument up until now.
