The application of multimedia teaching equipment enables the teachers to use multimedia computers and other equipment for human-machine interaction in order to complete the instruction. But the traditional manual management methods can't achieve the self-switching of multimedia equipment reducing the efficiency of multimedia teaching. A classroom multimedia teaching equipment management system based on embedded system with the introduction of the embedded and wireless transmission technology is designed and implements the distributed management of the equipments. The embedded system node installed in the multimedia device sets S3C2440 ARM9 embedded processor core as the core, works in the environment of the Linux OS, and implements the information processed locally. The server was accompanied by Zigbee wireless transceiver module for the use of information updating and system maintenance, so are the embedded nodes. Practical results demonstrate that the system has the characteristic of high processing speed and favorable stability which can meet the most of application demands and be worth popularizing.
