On the other hand, a distance measuring device that measures the distance from a distance measuring device to a wireless tag reciprocates a wireless signal between the wireless tag and the distance measuring device that measures the distance, and measures the distance from the time required for the reciprocation. There is a method of ranging from the device to the wireless tag.
The distance measuring device that measures the distance from the distance measuring device to the wireless tag from the time required for this round trip is not affected by the orientation of the wireless tag, so the distance measurement by the delay time is measured by the orientation of the wireless tag. There is a huge advantage that the accuracy does not change.
Therefore, in order to suppress the frequency of occurrence of traffic accidents, the inventor reciprocated a wireless signal between the distance measuring device of the latter method (a wireless tag and a distance measuring device for measuring distance).
