| Abstract: | The structure and realization method of a kind of moving vehicle detector in toll-station are introduced by this paper.The moving vehicle detector,which is based on inductive circular loop,detects the information of vehicles according to the inductive sig nal and send the information to the main controlling computer in re-mote supervising and controlling center.The technique of interference opposing ,such as analog ue sig nal filter-ing ,software tolerance and watchdog -reset circuit,g uarantees the detector working steadily under hard condi-tions. |
