摘　　要：该文介绍了一种网络数据采集系统的软硬件的实现。描述了数据采集模块中数据的存放顺序,着重讲述了Java与C的接口函数的写法和数据显示界面的设计。系统采用了Java、JavaServerPages、JavaScript等技术,利用接口函数编写了可以被jsp调用的动态链接库函数。该文介绍了动态链接库的使用方法。网络数据采集系统使得可以在远离现场的不同的PC机终端上通过internetexplore方便直观地观察现场正在采集的数据。该系统具有界面友好、操作简单、实时响应性好等特点,具有较高的实用价值。The realization of the software and hardware of a network data collecting system is introduced in this paper. The saving sequence of the data in the data collecting module is described. How to write the interface functions with java and c and the design of the interface of displaying data are described emphatically. Java, JavaServer Pages and JavaScript, and so on ,are adopted,and the functions of the dynamic library used by jsp are written. The method for using dynamic library is described. The data being collected can be observed through internet explore at pc terminals that are apart from the spot .The system has perfect practical values,with its friendly interface,excellent real-time response and operating simplicity.
