The invention provides an automatic anchoring and collision avoiding method for a ship under an urgent situation. The method comprises the following steps that: the outside is quantitatively analyzedby using a control system of a ship, and whether the urgent situation is formed with other ships or not is judged; when it is determined that other ships enter the urgent situation relative to the ship, the control system enters a take-over state and controls an anchor control system of the ship; the control system calculates the forward rushing distance and the chain extension length of the shipaccording to the azimuth angles of other ships relative to the ship, automatically selects an anchor falling point and opportunity to carry out anchor dropping braking, and then changes a current track of the ship by utilizing anchor resistance; and after the control system detects that the distance between the two ships meets the passing clearance rules, the control system drives the anchor weighing operation to return to an original preset flight path to continue sailing, and the takeover state of the control system is relieved. An AIS system of the ship is used for quantitative analysis, whether the urgent situation of the ship is formed or not is automatically judged, anchoring equipment is controlled in time, the forward rushing distance of the ship is controlled through autonomous anchoring, and timely steering and collision avoidance are achieved.
本发明提供一种紧迫局面下的船舶自动抛锚避碰方法,包括如下步骤:利用本船的控制系统对外界进行定量分析,判断与他船是否形成紧迫局面;确定他船进入相对本船的紧迫局面时,控制系统进入接管状态并对本船的锚控系统进行控制;控制系统根据他船相对本船的方位角,计算出本船的前冲距离和出链长度,自动选择落锚点和时机进行抛锚制动,然后利用锚阻改变本船现行航迹;控制系统检测到两船之间距离符合驶过让清规定后,驱动起锚操作,回到原预定航迹继续航行,并解除控制系统的接管状态。本发明利用船舶的AIS系统进行定量分析,自动判定本船紧迫局面是否形成,并及时对抛锚设备进行控制,采用自主抛锚来控制本船前冲距离,实现及时转向避撞。
