多媒体综合控制系统的几项关键技术

Several Key Technices about Multimedia Compositive Control System

文章阐述了多媒体综合控制系统的模块化设计思路与分布式控制原理 ,具体操作台模块、音频和视频切换模块、红外遥控模块、摄像机的镜头、云台控制模块的设计原理 ;提出在单片机多机数字通讯技术以及单片机与PC微机间数字通讯技术的基础上 ,如何实现分布式控制的基本手段 .系统的红外遥控模块具有“自学习”功能 ,可对大多数遥控器的编码进行“学习” ,将它们永久存入系统 ,因此该系统可以对大多数多媒体设备进行遥控 ,而不必改动设备的线路 .

This article expounds the modularization designed thought about multimedia comprehensive control system and the principle of the distributed control, and elucidates exactly the control principle of the operating desk module, the switch between audio and video module, the infrared remote control module and the vidicon glasses and cloud platform control module. The writer also suggests how does achieve the fundamental means of the distributed control that base on the multiple singlechip digital communication technique and the digital communication technique between singlechip and PC. The infrared remote control module in this system has the function of 'self study', and it can learn most of the coding of the infrared remote controllers and able to save them in this system. So this system can remote control most of multimedia equipment instead of change them circuitry.
