摘　　要：在自动化控制领域和实时数据采集系统中,经常使用串口控制外部设备或者从外部设备中读取数据,开发高效而快速的串口通信程序是必不可少的。在分析VS2008开发环境下几种常用串口通信实现方法的基础上,以农业生产中蔬菜大棚杀虫灯自动数据采集分析系统为实例,通过调用动态链接库中API库函数实现一种基于串口通信的数据采集分析系统。详细论述了串口数据采集分析系统的基本设计思路、程序控制流程和软件系统功能的实现。实践表明,在VS2008中调用API库函数可以快速建立串口通信,实现数据采集和控制外部设备,这种方式适用于距离较远、数据量大和通信质量要求较高的数据通信环境。数据采集分析系统设计合理,运行可靠,具有较强的实用性。In the automatic control field and real-time data acquisition system, often use the serial port to control external devices or read data from external devices, so to develop a highly efficient and rapid serial communication program is necessary. On the basis of analysis of some serial communication implementation methods in VS2008, this paper implements a data acquisition and analysis system based on the serial communication by calling the API library function of dynamic link library, taking the vegetable greenhouses insecticidal lamp automatic data acquisition and analysis system in agricultural production as an example. It describes in details main design ideas, the program control flow and the realization of software system function of serial port data acquisition analysis system. It is proved that calling API library function in VS2008 can quickly build the serial port communication, realize data acquisition and control external devices,, which applies to the data communication environment of long distance, large data amount and high quality data communication requirements. The data acquisition analysis system is designed reasonably, and it is reliably running, and having strong practicability.
