摘  要
基于網絡的虛擬實驗平臺是在能夠進行網絡通信的基礎之上將計算機上虛擬的各種儀器、器件，按實驗要求組裝成一個完整的實驗環境，實現搭接實驗電路，演示實驗過程等功能。遠程指導模塊是其中的一個功能模塊。它分成指導端和被指導端兩部分，指導端通過HOOK技術，采集本地機鼠標和鍵盤信息；然后將這些信息打包，通過P2P網絡通信機制將信息包傳給被指導端；在被指導端將信息包信息解出，通過mouse_event、keybd_event等函數去控制被指導端的鼠標、鍵盤動作,實現相關的一些遠程指導動作。本模塊在VC環境下開發，用到了Windows Socket編程技術，P2P編程思想，HOOK技術，多線程技術等多方面的技術。由于整個系統模塊很多，本設計中編寫了獨立的測試程序，經過測試基本達到預期的設計目標。

Design and Implementation of Remote Guidance Module Based on Network Virtual Experiment Platform
Abstract
Under the foundation of network communications，the network-based Virtual Experimental Platform could integrate various computer virtual devices into a complete experimental environment according to the experiment requirements, and connect the experiment circuit and demonstrate the process of experiment. The remote guiding module was one of function modules, which was divided into guiding end and the guided end. With HOOK, the guiding end captured the information of local mouse and keyboard, and packed the information to send to the guided part through peer-to-peer network communication mechanism. The guided end will unpack the information, and control the mouse and keyboard of the guided end by mouse_event, keybd_event functions to implement some remote control actions. Developed under VC environment, the remote guidance module used Windows Socket programming technology, P2P programming ideas, HOOK technology, multithreading technology, and etc. Because there are many modules for the whole system, an independent testing procedure was programmed to test the modules, which had been proven to achieve the desired objectives

Key words: Remote guidance；Peer-to-Peer；Windows Socket programming；HOOK；Multithreading
