基于VC++的XCTD串口实时数据采集系统的实现

Realization of XCTD serial real-time data acquisition system based on VC++

以863课题"XCTD投弃式温盐深剖面测量技术研究"为背景,提出了XCTD实时数据采集系统的设计方法。该系统以单片机和PC机为硬件平台,采用高精度16位Σ-ΔA/D转换器AD7705对采集到的信号进行A/D转换,通过串口进行数据通信。介绍了在VisualC++6.0软件开发环境下设计串口实时数据采集软件的方案和步骤,串行通信采用MSComm控件来实现,并给出了关键的代码与注释。测试结果表明该方案具有很好的准确性和实时性,满足课题需要。

The thesis’s background was the 863 project of Research of eXpendable Conductivity/Temperature/Depth Profiler（XCTD） Measurement Technology.Presented a design method of XCTD real-time data acquisition system.This system uses AT89S52 Microcontroller to collect data by controlling a 16-bit sigma-delta ADCs,AD7705 to carry out A/D conversion,and transfers data by serial port.Designed the system in the Visual C＋＋6.0 environment,and used MSComm control to realize serial communication.The corresponding codes are also given.The results of tests show that this system can be successfully achieved the accuracy and real-time of data collection.
