Design And Implemention On Network Monitoring And Control System Of Multimedia Teaching Equipment

Nowadays, multimedia classroom has become major teaching space of universities and various types of vocational training institutions. Multimedia classroom plays a very important role in teaching. The management of multimedia teaching equipment is directly related to teaching quality on campus. For the sake of solving problems in the use and management of multimedia teaching equipment, a monitoring and control system of multimedia teaching equipment based on campus network is in great demand.The core of this system is C8051F020 MCU. Its peripheral circuits are divided into four modules: equipment control module, RF reader module, video capture module and network communication module.The equipment control module is able to switch the output channel from several audio and video sources. Meanwhile, the switch of the main power, the projector and the projector screen can be operated by the control panel of the central control unit, as well as the operations of other multimedia teaching equipment.The RF reader module is made up of MFRC522 chip and its peripheral circuits. It can achieve the function of reading Mifare 1 S50 Card to identify the user.The video capture module can capture the real-time images of the equipment when it is working and compress them. These images are the basis of the remote control.The network communication module enables the communication between the central control system and remote monitoring computer by CP2200 Ethernet Controllor and embedded TCP/IP protocol stack.Comparing with the present design and product, the function of this system is more consummate by adding the capabilities of RF reader and videomonitoring. Furthermore, this system has moderate cost and practical function. It is able to solve present problems in the use and management of multimedia teaching equipment, which possesses a good market prospects.
