实现基于TCP LAN（局域网）内部的通讯、聊天、文件传送，模拟服务端对模拟客户端可以进行简单的远程控制。本系统的核心是采用VBJ技术、模拟数据库等有关技术开发的，因为采用VB技术的理由是，该技术易于服务器的维护，成本相对较低，开发周期较短。服务器选用Windows XP作为操作系统平台。-TCP LAN (local area network)-based internal communication, chat, file transfer, the simulation server impersonates the client can perform simple remote control

The system. The core of the system is VBJ technology, simulation database technology development using VB reason is that the technology is easy to

Maintenance of the device, the relatively low cost, shorter development cycle. Server to use Windows XP as the operating system platform.
