摘要
为提高船舶吃水检测精度,研制了基于STC8A8K+MS5837的高精度船舶吃水监测系统;该系统利用压力传感器MS5837高精度的特点,并结合液体压强与深度的关系解决船舶吃水测量精度低的问题,同时单片机STC8A8K将吃水数据通过RS485总线发送给上位机;上位机以Cortex-A9处理器为核心,搭载了Linux操作系统,液晶屏上可以显示实时数据,并且可以通过USB接口导出测量数据,保存数据以供后续研究;现场实验表明,该系统具有安装方便、实时性高的优点,其测量精度可达0.1 mm。
In order to improve the accuracy of ship draught measurement,a high-precision ship draught monitoring system based on STC8A8K+MS5837 was developed.According to the relationship between liquid pressure and depth,a high-precision pressure sensor MS5837 was applied to solve the problem of low accuracy in this system.Besides,the draught data is transmitted from the microcontroller STC8A8K to the host computer,which can display real-time data on the LCD screen and save the data for subsequent research.Field experiments demonstrate the system’s measurement accuracy can reach 0.1 mm with real-time performance,and it can be easily installed on ship.
