The invention relates to a collision acceleration gradient monitoring device which comprises a collision sensor, a display unit and an energy supply unit. The collision sensor comprises a plurality ofconductive carbon rods arranged in parallel, metal pieces arranged at the two ends of the conductive carbon rods in the length direction to form parallel connection of the conductive carbon rods, andmass blocks arranged in the middles of the conductive carbon rods in the length direction in an insulating mode. The metal pieces at the two ends are connected with the energy supply unit and the display unit through wires. The length direction of the conductive carbon rods is perpendicular to the collision direction, the masses of the mass blocks are sequentially reduced in the collision direction or the direction perpendicular to the collision direction, and the conductive carbon rods with different mass blocks are set to be in different thrust states when being collided to obtain differentcurrent values; the step where the acceleration of a collision body caused by collision is located can be obtained, the corresponding collision accident severity is obtained, and the device is low incost, good in durability, high in reliability, convenient to overhaul and replace and suitable for large-area and batch installation and use.
本发明涉及一种碰撞加速度梯度监测装置,包括碰撞传感器、显示单元和能量提供单元;所述碰撞传感器包括多个并列设置的导电碳棒、设置于导电碳棒沿长度方向的两端以形成多个导电碳棒并联连接的金属件及以绝缘方式设置于各导电碳棒沿长度方向中部的质量块;两端的金属件通过导线与能量提供单元和显示单元形成连接;导电碳棒的长度方向与碰撞方向垂直,并多个质量块的质量沿着碰撞方向或垂直于碰撞方向依次减小设置,在受到碰撞时设置不同质量块的导电碳棒呈现不同冲断状态以获取不同电流值;利于获取碰撞引起的碰撞体加速度所处梯级,以获得对应的碰撞事故严重程度,且成本低、耐久性好、可靠性高,便于检修更换,适于大面积、批量安装使用。
