Tidal level real time calculation system based on residual water level

为了有效控制附近海域潮位,保证通航安全和合理有效地利用水深资源,详述了余水位的基本原理和潮汐差分方法,提出了基于此理论的验潮方案和潮位推算算法,并开发了一个潮位实时推算系统。系统采用多线程、串口通信等技术,与GPS接收机、潮位遥报仪、电脑主机等硬件进行实时通讯,获取定位信息和遥报潮位等数据,利用差分潮位推算施工船舶所在位置处的高精度潮位,并同步将推算潮位传输给作业船舶指导施工。结果表明:该系统运行稳定、操作简便、运算高效、精确度高,满足潮位控制的精度要求。

In order to control the tidal level nearby the sea effectively,guarantee the navigation safety and make the best use of water depth,the theory of residual water level and tide difference were explained.Based on those theories, the solution of tide data collection and the calculation method were proposed, and a tide real time calculation system was designed. The technique of muhithread and serial port was used in the system to get the information of position and tidal level by communicating with GPS transceiver,telemetry tide gauge and computer.Then the high-precision tidal levels of the ship location were calculated by means of differential tide, and the calculated tidal level was sent to ship at the same time.The results show that the system has the advantages of stable operation, easy manipulation ,high efficiency and high accuracy, which satisfies the precision level of tide control.
