将网络技术融入数据采集系统使得原先在一台机器上完成的工作可以由多台机器分担 ,这使得数据采集站的负担大大减轻 ,数据分析的任务可以交给其他计算机完成。通过合理的资源配置 ,将可以大幅度提高系统的性能 ,并完成一些原先不可能完成的任务。与传统的 Client/Server结构不同 ,本文介绍了一种基于 Browser/Server结构的远程数据采集方法 ,利用通用网关接口 (CGI)进行远程数据采集 ,从而用一种更简洁的方式将数据采集系统与网络结合起来。同时论述了在 CGI程序中与设备驱动程序通讯实现数据采集的方法 ,并与其他方法进行了比较。最后通过实验证明 ,采用 Browser/Server结构进行远程数据采集是确实可行的 ,并且比传统的方法更为方便实用
The integration of network technology into the data acquisition system allows the work originally done on one machine to be shared by multiple machines, which greatly reduces the burden on the data collection station and allows the task of data analysis to be done by other computers. Through reasonable allocation of resources, it will greatly improve system performance and accomplish some tasks previously impossible. Different from the traditional Client / Server structure, this paper introduces a remote data acquisition method based on Browser / Server structure, using the common gateway interface (CGI) for remote data acquisition, so as to use a more concise way to connect the data acquisition system with Network together. At the same time, it discusses the method of data acquisition with device driver in CGI program and compares it with other methods. Finally, experiments show that using Browser / Server structure for remote data acquisition is feasible and more convenient and practical than the traditional method
