本文针对智能家庭网络中的家庭安防系统的需求,利用AVR 单片机ATmega64 接口多功耗低的特点,有效的整合图像传感器OV7670、图像压缩芯片VC0528 和无线射频模块nRF24L01 于一体,设计出一种基于M-JPEG 的无线低功耗摄像装置,并为智能家庭网络中的安防系统提供了一种低成本的设计方案。关键词:M-JPEG;无线;低功耗;摄像;智能家庭网络Abstract: A low-power wireless camera based on M-JPEG for the home guard in intelligenthome network is introduced in this paper. This camera is composed of three parts which are image processing module, control module and wireless communications module. We useMCU(ATmega64) to control sensor chip(OV7670), image compress chip(VC0528) and radiochip(nRF24L01). This camera is characterized by low-power, wireless and low-cost.Key Word: M-JPEG; Wireless; Low power; Camera; Intelligent home network
