目 录
引言
科技的进步，带来经济飞速发展的同时，也给人们的生活带来无限的惊奇。不断更新的生活方式，使得越来越多的人追求对生活的舒适度和享受度。智能家居作为新生力量呼之欲出，自然地走进我们的生活，随之，引领新一代的数字家庭生活。通过分析现有的智能家居解决方案，智能家居包括四个基本的功能模块：家庭对外通信模块、家庭网关模块、家庭安全防范模块、家庭设备自动控制模块。
本课题提取家庭安全防范模块研究，设计基于CAN总线的智能家居控制系统。安全防范就是保障人们在生产、生活和一切社会活动中人身生命、财产和生产、生活设施不受侵犯，防止侵害行为的总称。智能家居在满足人们舒适、方便生活的同时，也要求为家庭提供安全防范方面的保障。它包含的内容有防止入侵、盗窃、破坏、爆炸等，它的原则是“以防为主，打防并举”，安全防范
