Abstract

The invention discloses a collision detection device, an event data recorder comprising the same as well as a collision detection processing method. The collision detection device comprises a loudspeaker, a vibration signal conversion module and a signal processing module, wherein the loudspeaker is used for detecting vibration outside the collision detection device and generating vibration signals; the vibration signal conversion module is electrically connected with the loudspeaker and used for converting the vibration signals generated by the loudspeaker into electrical signals; the signal processing module is electrically connected with the vibration signal conversion module and used for processing the electrical signals generated by the vibration signal conversion module and determining whether the vibration signals are produced through collision. The collision detection device utilizes the loudspeaker for vibration detection, so that the collision detection cost is reduced greatly. Besides, with adoption of vibration detection, interference of sound similar to collision sound can be avoided to a great extent, the collision accident recognition rate is increased, and the detection signal acquisition cost is reduced. The event data recorder and the collision detection processing method provided by the invention also have the advantages.

Description

technical field [0001] The invention relates to the technical field of safety detection, in particular to a collision detection device, a driving recorder including the same, and a collision detection processing method. Background technique [0002] Drive recorder is installed on automobile, the instrument used for recording the relevent informations such as image and sound in vehicle traveling way. It can record the video image and sound of the whole process of vehicle driving, grasp the video data record of the scene of the accident, and the actual road conditions, which can be used as evidence of traffic accidents. [0003] In order to obtain clear and smooth video information, the amount of video data generated by the driving recorder is quite large under the condition of high resolution and high frame rate. Automatically overwrite the new screen on the original screen, and keep the scrolling record repeatedly. However, when an accident occurs, it is necessary to keep ...
