The invention discloses a geomagnetic system for counting traffic flow and a geomagnetic induction system. The geomagnetic system for counting traffic flow comprises a slave geomagnetic device and a master geomagnetic device, the slave geomagnetic device is arranged at the entrance and exit of the parking lot and is used for judging whether a vehicle passes through the slave geomagnetic device or not; the master geomagnetic device is in communication connection with the slave geomagnetic device, is spaced from the slave geomagnetic device by a preset distance, and is used for obtaining a judgment result of the slave geomagnetic device and judging whether a vehicle passes through the master geomagnetic device or not; and judging whether the vehicle completely passes through the entrance and exit of the parking lot or not according to the judgment result and the relative position between the slave geomagnetic device and the master geomagnetic device. Whether the vehicle completely passes through the entrance and exit of the parking lot can be judged, so that the vehicle running direction is accurately judged.
本发明公开了一种计数车流量地磁系统及地磁诱导系统,计数车流量地磁系统包括从地磁装置及主地磁装置;从地磁装置设于停车场出入口位置,用于判断车辆是否经过所述所述从地磁装置;主地磁装置与所述从地磁装置通信连接、且与所述从地磁装置间隔预设距离设置,用于获取所述从地磁装置的判断结果,及判断车辆是否经过所述主地磁装置,根据判断结果及所述从地磁装置与所述主地磁装置之间的相对位置判断车辆是否完整经过停车场出入口。可判断车辆是否完整经过停车场出入口,进而对车辆运行方向进行精准判断。
