【摘要】 本论文是由两个十五863立项课题组成,所属资源环境技术领域海洋环境监测技术主题,第一个课题为青年基金,名称“海水现场监测浊度传感器研制”,编号2002AA639520,起止时间2002年10月至2004年10月。第二个课题为第一个课题的延续,名称不变,编号2005AA635210。青年基金课题的主要目标是完成浊度传感器原理样机,第二个课题的主要目标是完成自容式浊度传感器和直读式浊度传感器工程样机各一台,本论文主要以第二个课题为基础完成的。自容式浊度传感器自带电源,可独立完成浊度值的测量,也可集成在水质监测仪或者浮标上。探头上装有毛刷,每次测量前清洗光学镜头,可防止污染和生物附着,解决海洋条件下长期现场测量问题。每个测量周期前,设定传感器工作时间和次数。测量周期完成后,取出所有测量的数据。直读式浊度传感器可实现海水现场快速测量,满足不同的海洋监测要求。有水下机和掌上机组成。水下机主要完成浊度值的测量,掌上机实现数据的显示、保存和电池管理等功能。在青年基金课题的基础上所完成的改进包括以下内容:1、改变测量量程,提高测量精度2、增加掌上机,形成直读式浊度传感器3、自容式浊度传感器4、人机界面的改进5、针对不同测量范围单独定标6、由原理样机转化为工程样机更多还原

【Abstract】 The paper contains two tasks, which belong to the key project of ocean environment monitor technology, resource environment technology field, one Ninth Five-Year Plan (2000-2005), National‘863’Hi-Tech R&D Program. The first is youth fund task, which name is the Developing of Turbidity Sensor on in-situ Oceanic observation, with serial number 2002AA639520 dating from 10/2002 to 10/2004. The second is its continuity, which name is not changed and which serial number is converted to 2005AA635210.The primary purpose of youth fund task is to complete principal instrument of turbidity sensor. The main intention of the second task is to accomplish every prototype of turbidity sensor and a direct-reading turbidity sensor. The paper is written based on the second task.Self-content turbidity sensor has its own battery and monitors water quality independently. It can be integrated on the water quality meter or buoy. Probe has a brush on the top, cleaning optic lens before each time of measuring, in order to prevent contamination and biosorption, with effectively being used for a long time in-situ oceanic measuring. At the beginning of being used in a period of time, it is needed to set work and work state; after the period, all data should be got from sensor.Direct-reading turbidity sensor is mostly used in quick measure for the different aim of monitoring water quality. It consists of under-water unit and palmar unit. Under water unit mostly fulfill measuring turbidity value and palmar unit can be used to display and save data form under-water unit, and manage battery and so on.Improvements on the base of youth fund task are listed as follows:1. change the measuring range to increase precision2. add palmar unit to form direct-reading turbidity sensor.3. manufacture self-content turbidity sensor.4. improve on operational interface.5. calibrate independently for every measuring range.6. change principal instrument to prototype.更多还原
