摘　　要：利用远红外热成像摄像机具有全天候工作的能力的特点,提出了桥梁防船撞远红外热成像预警技术.进一步研究大型桥梁引桥防船撞的自适应包裹来撞船首的拦截新技术,并提出产生恒定拖阻力的设计方法.并将提出的桥梁防船撞远红外热成像预警技术和自适应拦截技术应用于正在构建的平潭海峡大桥抗船舶撞击防护体系.This paper proposes a pre-warning technique using far-infrared thermal imaging to intercept vessels in risky circumstances. Because far-infrared thermal imaging camera is very sensitive to thermal radiation emanated from the detected objects, it works well and its functionality is independent of both lumination and weather condition. In this paper, the adaptive rising net to capture ship is developed, and the design method to produce a constant resistant force is also proposed. The both developed techniques are applied in Pingtan Strait Bridge to build up a protection system from ship accidental collision.
