基于C++Builder的串口数据实时曲线绘制的实现

Realization of serial data real-time curve drawing based on C++ builder

介绍了在C++Builder 6.0软件开发环境下设计温盐深实时数据采集与处理系统的方法,其中PC机与数据接收装置之间的串行通信采用MSComm串行通信控件来实现,并给出了相应的程序代码,利用模拟数据源模拟现场采集数据,将实地测量得到的温度和电导率值依次通过串口传输到本软件中,结果证实系统运行稳定,该后台软件以实时曲线绘制的方式形象、直观地显示了采集的温盐深数据,并能把盐度、密度、声速的曲线绘制出来,运行良好。

Introduced in C＋＋ Builder 6.0 software development environment design temperature salt deep real-time data acquisition and processing system,including PCs and data receiving device of serial communication between using MSComm serial communication controls to implement,and the corresponding program code,using the real field data collection,probe simulation will be measured temperature field and electrical conductivity value in turn through serial transmission to the software,the results confirm the system runs stably,this backend software to real-time curve drawing way image,intuitive shows the acquisition of the temperature deep data,and salt can salinity,density,velocity of curve mapped out,work well.
