The invention discloses a bridge active ship collision prevention early warning system based on AIS data. The bridge active ship collision prevention early warning system comprises a high-definition camera system, a laser emitter, a bridge collision prevention safety management platform, a shore-based AIS data receiver, a fortified bridge and a laser receiver. The ship is identified and tracked through a visible light camera system and an infrared thermal image camera, meanwhile, the shore-based AIS data receiver is used for obtaining information such as the main scale, the navigational speed, the navigational direction and the navigational direction change rate of the related ship, the ship navigation track is calculated according to the information, the bridge collision risk is evaluated, and if the navigation risk is large, the warning device is started immediately, and strong light, voice broadcast and maritime radio stations are used for reminding the ship to take danger avoiding measures in time in multiple ways.
本发明公开了一种基于AIS数据的桥梁主动防船撞预警系统,包括高清摄像系统、激光发射仪、桥梁防撞安全管理平台、岸基AIS数据接受仪、设防桥梁、激光接受仪。本发明通过可见光摄像系统、红外热像摄像识别跟踪船只,同时利用岸基AIS数据接受仪获得相关船只的主尺度、航速、航向、航向改变率等信息,根据以上信息计算船舶航行轨迹并评估对桥撞击风险,若航行风险较大,告警装置随即启动,利用强光、语音播报及海事电台多途径提醒船舶及时采取避险措施。
