多媒体教学设备网络监控系统的设计与实现
|
摘要
目前多媒体教室已成为各大高校以及各类职业培训机构的主要教学场地,在教学活动中发挥着非常重要的作用。而多媒体教学设备管理的好坏将直接关系到课堂知识的传授效果和学校的教学质量。为解决现阶段多媒体教学设备使用和管理上存在的问题,需要设计一套基于校园网络的多媒体教学设备监控系统。
系统以C8051F020单片机作为控制核心。其外围电路分为四个模块:设备控制模块、射频读卡模块、视频采集模块和网络通信模块。
设备控制模块具有多路音视频源的输出切换功能,还能通过中控器面板实现设备总电源的关闭操作、投影机的开关操作、电动投影幕的升降操作以及其他多媒体设备的常见操作。射频读卡模块主要由MFRC522芯片及其外围电路构成,可实现Mifare 1 S50卡的读卡功能,从而辨识使用者的身份。视频采集模块可以捕捉到设备工作状态的实时图像并进行压缩,为远程控制提供依据。网络通信模块利用CP2200以太网控制芯片和嵌入式TCP/IP协议栈实现中控系统与远程监控计算机的数据通信功能。
相比现有的设计方案及产品,本系统添加了射频读卡和视频监控功能,产品功能更加完善。此外,本系统成本合理,功能实用,能解决现阶段多媒体教学设备的使用和管理上存在问题,具有一定的市场前景。
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.
