A collision safety threshold is programmed and preset in the information acquisition and analysis module (2) in advance. If an analysis result of the information acquisition and analysis module (2) is lower than the safety threshold, i.e., there is going to be a collision, then a signal instruction is immediately transmitted to the safety airbag module (3), such that the safety airbag module (3) deploys a safety airbag before the collision occurs.

  2. 根据权利要求1所述的带有安全气囊的防撞护栏，其特征在于，所述的防撞护栏基体材料为钢筋混凝土、金属、高分子材料、复合材料任意一种或任意几种以任意比的混合物。The anti-collision guardrail with an airbag according to claim 1, wherein the anti-collision guardrail base material is any one of reinforced concrete, metal, polymer material, composite material or any ratio of any one of them. mixture.
  3. 根据权利要求1所述的带有安全气囊的防撞护栏，其特征在于，所述的信息采集分析模块包含有距离采集单元、速度分析单元、行驶方向分析单元、碰撞分析单元。The anti-collision guardrail with an airbag according to claim 1, wherein the information collection and analysis module comprises a distance collecting unit, a speed analyzing unit, a driving direction analyzing unit, and a collision analyzing unit.
  4. 根据权利要求1所述的带有安全气囊的防撞护栏，其特征在于，所述的安全气囊模块包括时间比较单元、安全气囊弹出单元、安全气囊回收单元，当确认碰撞必然发生时，安全气囊模块接受信息采集分析模块传递的信号后，通过时间比较单元分析，对信号进行二次分析判定，安全气囊的弹出时间可以通过相关的程序编程进行控制，安全气囊弹出单元便会在小于碰撞时间内弹出安全气囊，当碰撞结束后，安全气囊回收单元工作，将安全气囊回收进防撞护栏基体内。 The anti-collision guardrail with an airbag according to claim 1, wherein the airbag module comprises a time comparison unit, an airbag ejecting unit, and an airbag recovery unit, and when the collision is inevitable, the airbag is instructed. After receiving the signal transmitted by the information acquisition and analysis module, the module analyzes the signal through the time comparison unit, and the airbag pop-up time can be controlled by relevant program programming. The airbag pop-up unit will be less than the collision time. The airbag is ejected. When the collision is over, the airbag recovery unit works to recover the airbag into the collision barrier base.
