智能監(jiān)控系統(tǒng)由現(xiàn)場設(shè)備、嵌入式WEB 服務(wù)器、無線傳輸網(wǎng)絡(luò)和監(jiān)控中心組成。嵌入式WEB 服務(wù) 器是系統(tǒng)的核心，主要由嵌入式微處理器MPC8250、無線數(shù)據(jù)傳輸模塊、MPEG-4 視音頻編碼模塊、云臺(tái) 控制模塊、無線網(wǎng)卡、大容量硬盤等組成。監(jiān)控中心的用戶無需使用專用軟件，通過瀏覽器便可直接觀看 Web 服務(wù)器上的攝像機(jī)圖像和報(bào)警信息，并可根據(jù)需要向服務(wù)器發(fā)送視頻請求以及對攝像機(jī)的控制信號(hào)。 關(guān)鍵詞：WLAN；嵌入式微處理器；嵌入式Web服務(wù)器；視音頻編碼

Design of Intelligent Monitoring and Control System Based on WLAN Liu Jie 1, Xiao zheng hong1, Zhang xiao-hu 2 (1. Hunan University of Arts and Science of Computer Science and Technology Department, Changde 415000 China; 2. Hunan University of Arts and Science of Electrician Department, Changde 415000 China;) Abstract: Intelligent monitoring and control system include locale equipment, embedded web server, wireless network, and monitoring & control center. Embedded web server is the core of the system. It consists of embedded
CPU MPC8250, wireless data transmitting module, MPEG-4 video and audio coding module, tile controlling
module, wireless network card and hard disk with big capacity. Users can watch the video and alarm message,
which come from the web server, without special software. For the more, they can also ask the web server for
video transmitting and tile controlling according to their requirement.
