Abstract

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.

Claims

1. A moving body anti-collision device that is provided on a moving body and transmits signals to or receives signals from other moving body, comprising;

a transmission unit that transmits a detection wave;

a driving unit that is connected to the transmission unit and generates a driving signal to drive the transmission unit;

a receiving unit that receives a detection wave sent from a transmission unit provided on the 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.

2. The moving body anti-collision device as claimed in claim 1, wherein,

the driving unit drives the transmission unit to transmit the detection wave with a predetermined transmission intensity.

3. The moving body anti-collision device as claimed in claim 1, wherein,

the driving unit drives the transmission unit to transmit the detection wave with a variable transmission intensity.

4. The moving body anti-collision device as claimed in claim 1, wherein,

the calculating unit calculates a distance to the other moving body according to the intensity of the received detection wave.

5. The moving body anti-collision device as claimed in claim 1, wherein,

information of the moving body is included in the detection wave sent by the transmission unit.

6. The moving body anti-collision device as claimed in claim 5, wherein

the information of the moving body included in the detection wave includes one or more of transmission intensity information of the detection wave, speed information of the moving body, moving direction information of the moving body, operation information of the moving body, ID information of the moving body, and type information of the moving body.

7. The moving body anti-collision device as claimed in claim 1, wherein

the driving unit determines the transmission intensity of the detection wave according to a speed of the moving body.

8. The moving body anti-collision device as claimed in claim 1, further comprising:

one or more of a speed sensor that detects a speed of the moving body, a direction sensor that detects a moving direction of the moving body, and an operation detection unit that detects an operation of the moving body.

9. The moving body anti-collision device as claimed in one of claims 1, further comprising:

a display unit that displays the relative position between the moving body and the other moving body.

10. The moving body anti-collision device as claimed in claim 5, further comprising:

a notification unit that notifies an operator of the moving body,

wherein

when operation information included in the detection wave of the other moving body in the moving direction of the moving body is braking or acceleration, the notification unit transmits a warning message to notify the operator to brake or accelerate the moving body.
