parking area (1) entrance is provided with two earth magnetism sensing formula spikes (5) at least at the interval: the track spike is a first track spike and a second track spike; after the vehicle passes through the first spike, the first spike sends vehicle passing information to the LoRa gateway (3), the LoRa gateway (3) identifies that the information source is the first spike speed measurement and detection according to the equipment ID of the spike, at the moment, the LoRa gateway (3) records the millisecond time of receiving the first spike, the LoRa gateway (3) records the time of receiving the second spike after the vehicle passes through the second spike in the same way, the time of receiving the first spike speed information subtracted from the time of receiving the second spike speed information is delta t, the standard of the mounting interval of the first spike speed measurement and detection is delta s during mounting, the vehicle speed v can be calculated, the delta s/delta t can be calculated, and when one vehicle speed is detected, the vehicle flow count is increased by one.
