摘　　要：为实时了解船舶在航行时的地理位置、行驶速度、温度,提出一种新型智能航标灯系统。该系统拥有基本的视觉导航功能,能使船舶分辨出航道的具体位置。通过在航标灯上安装GPS与北斗双模定位模块,并运用Lora通信与3G/4G通信这两种方式,使船舶的监测数据传输到监控终端,以保障航道的正常与船舶的安全通行。另外,利用三轴加速度传感器测量船舶运行的速度、电压传感器测量Lora Tracker工作电压,来判断系统稳定性。通过对大量节点进行测试,可以得到船的位置、温度、风速、稳定性等信息。在正常工作情况下,位置信息误差在0.1 m以内,温度、风速等信息基本没有误差。In order to monitor the ship’s geographical location,driving speed and temperature in real time,a new intelligent navigation-mark light system is proposed.It has the basic visual navigation function that enables the ship to distinguish the specific location of the channel.By installing GPS and Beidou dual-mode positioning modules on the navigation-mark lights,the monitoring terminal can receive the monitoring data of the ship through LoraWAN and 3G/4G,which can guarantee the normal channel and safe passage of the ship.In addition,the three-axis acceleration sensor and the voltage sensor are used to measure the speed of shipping lines and the working voltage of Lora Tracker to judge the system stability.By testing a large number of nodes,the ship’s location,temperature,wind speed and stability and other information can be obtained.Under normal working conditions,the location information error is within 0.1 m,and there is almost no error in temperature and wind speed information.
