The invention provides a black box of an anti-collision warning device and a collision data recording method, the black box comprises a protective shell and a built-in data storage module, the protective shell is also internally provided with a gyroscope for detecting an inclination angle value in a vertical direction and an acceleration sensor for detecting an acceleration value in a horizontal direction; the collision data recording method comprises the following steps: acquiring an inclination angle value in real time through a gyroscope, and acquiring an acceleration value in real time through an acceleration sensor; when the inclination angle value and the acceleration value which are measured in real time are larger than preset values, it is judged that the vehicle collides with the anti-collision warning device, then a collision log is triggered to be written into the data storage module, and the collision log comprises the acceleration value and the inclination angle value. Whether the anti-collision warning device collides and turns over or not is judged according to the inclination angle value and the acceleration value, corresponding data are recorded, a collision log is formed, and a basis is provided for follow-up accident investigation.
本发明提出一种防撞警示装置的黑匣子和碰撞数据记录方法,该黑匣子包括保护壳及内置的数据存储模块,所述保护壳内还设有用于检测垂直方向的倾斜角度值的陀螺仪,以及用于检测水平方向的加速度值的加速度传感器;该碰撞数据记录方法包括以下步骤:通过陀螺仪实时获取倾斜角度值,通过加速度传感器实时获取加速度值;当实时所测的倾斜角度值和加速度值大于预设值时,判定为车辆与防撞警示装置发生碰撞,继而触发向数据存储模块中写入碰撞日志,所述碰撞日志中包含加速度值和倾斜角度值。本发明通过倾斜角度值和加速度值来判断防撞警示装置是否发生碰撞、翻侧并记录对应的数据,形成碰撞日志,为后续事故侦查提供依据。
