Abstract:Anisotropic MagnetoResistive(AMR) sensor senses disturbance of earth’s magnetic field caused by a vehicle over sensor and produces an output clear DC signal.Through the slicing algorithm,all kinds of vehicle information can be gotten,such as traffic volumes,vehicle speed,length of vehicle and the type of vehicle.Now,Geomagnetic Vehicle Detector(GVD) is to be an attractive alternative to inductive loops.According to the research results in native and abroad,this paper classifies vehicle algorithm based on AMR sensors by what object it study.Lastly,this paper concludes questions existing in above algorithms and proposes a vehicle detecting technology on the magnetic declination.
Keywords:magnetoresistive effect  Anisotropic MagnetoResistiv(AMR)  vehicle detection  Geomagnetic Vehicle Detector(GVD)  time series
