Network remote control is a major advantage in network management, remote collaboration, remote office and other computer fields have a wide range of applications, it further to overcome regional differences in the operation brought the inconvenience, making the network efficiency Given greater play. Remote control can be achieved through a variety of ways.Keywords: remote control; remote operation; technology; Implementation1 computer remote control Computer remote control is on the network by a computer (host Remote / Client) remote to control another computer technology . Here is not the literal meaning of the long-distance remote, but rather through the network to the remote computer on the implementation of remote control. Remote control is to manipulate the computer through the network as a means only, if used properly, will control the remote computer as you manipulate the front of the computer being used as there is no difference. When the operator using the host computer control host computer to host computer as if sitting in front of the screen as the computer can start the host application, you can use the host computer documentation, or even Host computer using the external printing device and communications equipment to print and access the Internet. In this process, host computer is just a keyboard and mouse commands sent to the remote computer, while host computers screen image come through the communication line return. That is, we control the host computer to operate in front of the computer seems to be carried out, in essence, a remote computer to achieve, whether to open the file, or Web browsing, downloading, all the information and the Internet are all Stored in the remote host computer. Implementation of remote control, in fact, a server program (hereinafter referred to as charged program) and a client (hereinafter referred to as master control program), the prosecution is the server program that listens to customer requests, and to deal with it; Master Is the client side, it is connected to the server, to make their request, the server will be made according to customers request a different response. Remote control system shown in Figure 1. Todays technical support network remote control methods are: LAN, WAN, dial-up Internet way. In addition, some remote control software also supports serial, parallel, infrared port to control a remote machine. Remote control to overcome regional differences in the operation brought the inconvenience, make the network to play a greater efficiency.2 remote control technology2.1 Principles of remote control As long as the network has access to connect remote control , remote control must be carried out through the network. At local, has been installed, the host is a client program to issue control instructions side, it is the same as an ordinary customer to non-local, the installation of the host server program signals, and through the establishment of a special Remote service, using a variety of remote control function to send a remote control command, control, host computers running various applications, making the host in accordance with the masters Requirements for various operations, in order to achieve the remote control. Figure 2 Schematic diagram of the remote control Remote control through the network diagram shown in Figure 2.2.2Implementation of Remote Control2.2.1 Microsoft Windows XP system using the remote control function Windows XP computers each include both client and server side, meaning that both can be used as a client to connect to other Windows XP computer, you can also themselves as the server side, so that other computer to control themselves. Server systems are using Windows XP, the client can be Windows XP, Windows 2000 or Windows Me, and the client without language restrictions. Users can use the Remote Desktop computer through the network to the remote control, after controlling for access to all applications, files and network resources.2.2.2 using some powerful remote control software. Remote control technology to today, have a lot of great remote control software, providing multi-level security protection for remote control software, as well as speed up the remote control operating software, and more conducive to the rapid document transmission control software. Also, as RemotelyAnywhere just a one-time installation on the server side, the client in the network do not need to add any software to connect directly through the browser on the server for remote control. It is not just the client to remotely control the servers desktop, but also can set different permissions for multiple users so that they are under the authority of the servers file manager, registry, query and manage projects; it allows the server and Clipboard passed between the client can also be transmitted to achieve common document. In addition, some set of remote control, data communications and file transfer and other functions into one, with high data transmission efficiency and system security remote control system is being promoted.2.2.3 Development and implementation of the actual needs of the remote control Develop their own remote control, involving the host computer and controlled machines, so the use of Client / Server structure. Delphi programming environment can be used separately on two different computers to be controlled preparation of control and procedures, one for Clientdpr. exe, installed in the controlled machine; one for Serverdpr. exe, installed in the main computer on. Serverdpr. exe designated to monitor the controlled machine IP address and send instructions to the client Clientdpr. exe, client Clientdpr. exe get command, and then execute the corresponding instructions in the machine, the results are returned to the host computer. Master side function is implemented as follows: Read command string into a strin
