Multi-function Intelligent Instrument of Vehicle Speed Detection based on Embedded System

摘要

By analyzing all kinds of application situation about speed test-bed, a multi-function intelligent instrument of speed detection based on embedded system was designed. This paper described its operation principle, hardware constitution and design method of system software. It has such function as data acquisition, data processing and fault diagnosis etc. This instrumentation not only fits for many speed sensors. But also satisfies different application situations. The application results indicate that it is not only a low cost and highly universal detection instrument of speed, but also the only kind of small-scale multi-function instrument up until now.
