摘 要随着社会的迅速发展，科技技术的突飞猛进，无线视频监控系统眼下名声鹊起成为炙手可热的话题。这其中除了电子通信技术与信息处理技术的发展为其构筑了技术平台之外，还有一个重要的原因就是社会需求的推动。由于无线视频监控系统的安全、方便、直观和信息内容丰富，被广泛用于各个场合。在银行室内或地下煤矿工作等场合使用无线视频监控系统，检测安全性是非常必要的。运用 C8051F 系列单片机和 NRF905 收发模块进行设计。摄像头所采集到的图像信号转换成模拟电压信号，送入到混频电路，混出射频信号，最后放大后发送出去。射频无线接收电路接收信号并送入显示器显示图像信号。C8051F 系列单片机通过 SPI 串口程序在数字无线发射电路中主要负责按键的控制，52 系列单片机用来控制 HY12864 液晶进行字符串的显示和按键具体情况。数字无线接收电路实现摄像头电机方向控制。关键词：无线视频监控系统；C8051F 系列单片机；NRF905 发射与接收模块；HY12864 液晶ABSTRACTWith the rapid development of society, science and technology is advancing rapidly, the reputation of a wireless monitor system is being held in high value and is a topic of the supreme arrogance of a person with great power at this stage. Besides technology of electron communication and information disposition is constructing a technology of platform, the important reason is requirement of society is impelled. Due to a wireless monitor system is safety、convenience 、directly perceived through the senses and abundant of content, we used it to every occasion widely. It is very necessary to detect security with a wireless monitor system is in occasion of bank room or the collieries of underground etc. We make use of C8051F series single chip microcomputer and nRF905 wireless emissive and receiving module to design.Vidicon switches image signals of collect to analog voltage signals, deliver to the mixer，come out radio frequency signals, blowup and deliver in the end. A receiver of wireless radio frequency receive image signals、deliver this signals to display to and show them. In digital emissive electrocircuit of wireless, C8051F series single chip microcomputer use SPI make use of program to take charge key-press, 52 series single chip microcomputer control HY12864 LCD（Liquid Crystal Display） to display character string and the circumstances of key-press. Digital receiver of wireless control the bearing of vidicon electric machinery.Keywords：A wireless monitor system
