Moving body anti-collision device and moving body with the same

摘要

A moving body anti-collision device is disclosed that is able to accurately determine a relative position between moving bodies in a small area and efficiently prevent collisions between moving bodies. The moving body anti-collision device includes a transmission unit that transmits a detection wave, a driving unit that generates a driving signal to drive the transmission unit, a receiving unit that receives a detection wave sent from a transmission unit on other moving body, a calculation unit that calculates a relative position of the moving body relative to the other moving body according to an intensity of the detection wave sent from the other moving body and received by the receiving unit, and a collision determining unit that determines, according to a calculation result given by the calculating unit, whether the moving body collide with the other moving body.

主权项

1. A moving body anti-collision device that is provided on a moving body and transmits signals to or receives signals from another moving body, comprising:
a transmission unit that transmits a first detection wave; a driving unit that is connected to the transmission unit and generates a driving signal to drive the transmission unit; a first receiving unit that receives a second detection wave sent from a transmission unit provided on the other moving body; a calculation unit that calculates a position of the moving body relative to the other moving body based on an intensity of the second detection wave received by the first receiving unit, information included in the second detection wave indicating the transmission intensity of the second detection wave, and an intensity-distance curve, wherein, in the intensity-distance curve, the intensity of the second detection wave decreases as a propagation distance increases; and a collision determining unit that determines, based on a calculation result given by the calculating unit, whether the moving body collides with the other moving body, wherein transmission intensity of the second detection wave is set in the other moving body based on a speed at which the other moving body travels.
