The invention relates to a method for monitoring the floating state of a ship in a dock. The method comprises the following steps that a laser swinger is arranged to project a laser horizontal line; mounting a receiver; the relative position of the laser horizontal line and the receiver is judged by listening to a sound signal of the receiver; when the receiver stops sending the sound signal, judging that the ship leaves the pier and is in a floating state, and reading the draft depth of the water gauge at the position; and the ship is subjected to secondary pier falling positioning, the dock continuously drains water, and when the receiver continuously sends sound signals again and checks that the laser horizontal line passes through the center line of the induction window of the receiver, it is judged that the ship is in a pier falling state at the position. According to the method for monitoring the floating state of the ship in the dock, the equipment cost and the labor amount are saved, operation is easy, and judgment is accurate and timely.

    本发明涉及一种监控坞内船舶起浮状态的方法,包括以下步骤:设置激光扫平仪以投射激光水平线;安装接收器;通过听取接收器的声音信号判定激光水平线与接收器的相对位置;当接收器停止发出声音信号时,判定船舶已离墩并处于起浮状态,读取该处水尺吃水深度;船舶二次落墩定位,船坞持续排水,当接收器再次持续发出声音信号,查看激光水平线经过接收器感应窗口中心线时,判定船舶在该位置处于落墩状态。本发明的一种监控坞内船舶起浮状态的方法,以节约设备成本和劳动量,操作简单,判定准确且及时。
