基于CPCI总线的雷达数据采集与控制系统显控软件设计

CPCI总线作为PCI总线的加固版本，目前已成为计算机上流行的高速外设接口总线。在工业自动化领域，进行数据采集和控制基本上也都是通过这一成熟技术来实现的。本文简要介绍该测量雷达和数据采集与控制系统的基本结构，以及CPCI总线标准，重点分析显控软件的功能需求，采用自顶向下的设计，并在VC环境下基于MFC架构利用多线程和双缓存技术以及多种ActiveX控件进行显控软件设计。实现了对测量雷达的控制以及对雷达回波的原始数据的实时存取和绘制。

Design of Display and Control Software of Radar Data Acquisition and Control System Based on CPCI Bus

CPCI bus is the reinforced edition of PCI bus and is the one of the highest speed peripheral interface bus in computer.In automatic control field of industry, data acquisition and control system is using the mature technique. This paper describes the constitute of the measuring radar and data acquisition and control system structure,and also CPCI bus criterion. The key point is focused on function requirements of display and control software which use Top-Down design method. Display and control software is designed by using multi-thread and double buffer and Active X controls based on MFC in the Visual C environment. Display and control software realizes to control the measuring radar, and also to real time store and display raw data of radar echo.
