|
摘要
为了快速、实时完成对国产Argo浮标密度的精确测算及验证,设计了一套基于ARM9硬件平台和WinCE嵌入式操作系统的浮标密度实时监测仪。该监测仪通过在线接收水下温盐深仪的温度、电导率、压力三种原始测量数据,并以现场测量得到的浮标质量等物理量作为输入,计算得到浮标在预定压力下的密度,在LCD屏上实时显示,并具备数据计算分析、存储等功能。该监测仪可完全替代传统测量方式,实时性强、操作简单、使用方式灵活,可快速应用在国产Argo浮标研制生产过程中浮标密度、水面浮力测算等关键步骤,具有很强的实用价值。
In order to accomplish accurate calculation and verification of homemade Argo buoy's density fast and in real-time, a buoy density real-time monitor based on ARM9 hardware platform and WinCE embedded operating system is designed. This monitor receives three primal measurement data such as temperature, conductivity and pressure of underwater CTD system online, takes physical quantities such as buoy's mass measured on the spot as input, and calculates density of buoy under preset pressure and displays it on LCD screen, and it has functions of data calculation, analysis and storage. Based on the advantages of good real-time performance, simple operation and flexible usage mode,this monitor can replace the traditional measurement methods completely and be applied in critical steps of development and production process of homemade Argo buoy such as measurement of buoy's density and buoyancy, and it has great practical value.
