The Design Of Embedded Conference Central Control System Touch Screen Terminal

Conference central control system is a high-tech product of modern conferencing systems, research and improvement in the control system of the conference is a major work for many manufacturers at present. This design is based on the research to the present conference central control system. The author uses S3C6410 ARM processor as system core, based on embedded Linux system, Designs and implements a touch screen control terminal for the conference.The author dose research and analysis for the solutions of currently products, Constructs of the overall framework of the system, and chooses the hardware and software platforms, at the same time builds the system development envir onment.Based on infrared remote control coding theory, the author achieves self-learning function by a method of recording IR waves, and designs the Linux drivers for the IR receiving and sending modules which provides the interface for the IR learning function. After adding the IR learning function to the system, it is easier to control the IR devices.An improved embedded encryption protocol for this system is designed by analyzing the computer network security and data encryption mechanisms, and based on the theory of SSL encryption protocol. This method improves the Security and stability of the system.By analyzing the implementation of Human-Computer Interaction, the author designs and implements the function of dynamic interface and interactive control, at the time designs self-learning UI for the IR learning function.
