The present invention relates to a bicycle black box using a radar sensor, comprising: a power supply part (10) which supplies power; a switch part (20) which controls power supply of the power supply part (10) by switching; a radar sensor part (30) which receives the power of the power supply part (10) through the switch part (20), and detects a relative speed of an approaching object using a radar signal; a control part (40) which predicts an accident using a relative speed set by determining a detection result of the radar sensor part (30), and outputs a control signal depending on a result of the accident prediction; and a camera part (50) which receives the power of the power supply part (10) through the switch part (20) in response to the control signal, and photographs images and stores the images in a memory part (60) if the control part (40) predicts an accident. According to the present invention, an accident is predicted by determining a distance from an object and approach of the object by the radar sensor, and images are photographed when the accident is predicted, thereby minimizing battery consumption and the size of stored images. |
