摘要
MARK-ⅢCTD数据采集系统经改进后能与MX-1102卫星定位仪、IBM—PC/XT微机联机,它除了保持原系统的功能外,还能够采集站位水深等数据和记录CTD探头进水过程;采集的数据及时储存在IBM-PC/XT磁盘,采样率达10％;操作简便,克服了采集到HP-85微机内存的数据易丢失和现场测量压力传感器零点难以准确等缺点。IBM-FC/XT的数据供脱机绘“垂直分布图”、“温-盐关系图”和计算十要素“标准层”等预处理采用;数据处理规格化,对发挥该系统性能、标准层处理和数据后处理都比较有效。经多年的应用表明,有推广价值。
This paper introduces the improvement on MARK-Ⅲ CTD data acquisition system by connecting a HP-85 microcomputer, MX-1102 satellite positioner and IBM-PC/XT together. This system with HP-85 maintains the functions of the original MARK-ⅢCTD system. It is also characterized by automatically collecting data of stations and the CTD, controlling the activation and data storage of IBM-PC/XT, reaching a data collecting rate as high as 10%, automatically recording the process of water entering into the CTD probe and easy operation.Moreover the pre-handling of data is more perfect and standardized. This system can be used in similar systems.
