【摘要】 本论文以Internet在远程控制上的应用为研究背景，以远程完成三相电路实验为具体研究目的。首先讨论了国内外相关研究课题的发展现状、与本课题的类似性和区别，本课题所具有的独特的特点和在教学中的应用价值。然后介绍系统的软、硬件设计，硬件设计中详细阐述了计算机并行端口的特性和控制原理、外围硬件控制电路设计方法和控制原理，软件部分包括ASP动态页面、SQL数据库、并行端口控制程序编制等。在介绍软、硬件设计过程中，穿插系统软、硬件协调工作的原理。对系统采集的实验数据用曲线拟合的最小二乘法进行处理，完成实验数据的非线性矫正。最后，对系统的软、硬件设计进行客观的分析，提出系统存在的缺点和局限性，对系统的进一步改进、优化做出展望。更多还原

【Abstract】 This dissertation take the application of Internet in the long-distance control as research background, take accomplishment of three-phase circuit experiment in the distance as research purpose. Firstly, the dissertation discuss the current development of correlated subject around the world, the similarity and difference with these subjects, the unique characteristic and the value of application in the learn. Further more, the dissertation introduce the design of software and hardware of system. In hardware design, there expound the characteristic and control principle of computer parallel port, the design method and control principle of periphery control circuit. The software parts include ASP, SQL database, control program of parallel port etc. There insert the principle of cooperation of system hardware and software in the process of introducing the design of hardware and software. The experiment data collected by system is be disposed by Least square method that the contours fit, which adjust the non-linearity of experiment data. Finally, we analysis the design of hardware and software of system externally, put forward the disadvantage and limitation of system, and give the prospect of further optimization and improvement of system.更多还原
