摘要
通过采用质量较好的H.264编码方案和支持IEEE802.11N的传输及终端设备,并考虑向下兼容的情况下,设计了基于WLAN(无线局域网)的监控系统,该系统能保证监控中心得到清晰、连续的视频信号。现场测试时考虑了恶劣天气、障碍物、通信距离以及电磁干扰等因素,结果表明系统能较好地完成实时监控,具有组网简单、实时传输等特点。
With the development of wireless network technology and wireless mobile devices,wireless environment-oriented technology will increasingly become a hot topic. This paper presents a wireless LAN based monitoring program,using H. 264 /MPEG-4 video compression coding technology and IEEE 802. 11 n standard equipment. Being compatible with existing equipments,this program can ensure the quality of data compression and data transfer rate. Taking tests considering distractions like weather,distance,obstacles and radio interference,this program proved to be able to achieve fast speed of setting wireless network,as well as satisfactory results of real-time monitoring,and real-time data transmission.
