文档介绍：I 摘要随着房地产业的发展,与之密切关联的楼宇对讲产业也得到了迅速地发展,并为之形成了安防行业,楼宇可视对讲系统就属于安防产品之一。楼宇可视对讲是一套现代化的小康住宅服务措施,它主要运用于住宅,可以是大面积的住宅小区,也可以是单栋的楼宇住宅。楼宇对讲系统是利用语音技术、视频技术、控制技术和计算机技术实现楼宇内外业主和访客间的语音、视频、对讲和通话的系统,通过扩展可实现信息的发布、家电的控制、安防报警、录音和录像等功能。本次毕业设计主要是运用模拟电子技术、数字电子技术以及 EDA 技术、传感器等知识来设计楼宇可视对讲系统的基本功能,这些基本功能包括呼叫功能、可视功能、对讲功能、开锁功能以及监视功能等。这次毕业设计的楼宇对讲系统实现了基本的呼叫、可视、对讲、开锁等功能,通过外围电路的扩展还能实现分机与管理中心管理机的通话、求助等功能以及主机对管理机的呼叫等功能,扩展性较好,还有更广泛的研究空间。关键词楼宇对讲系统, EDA 技术,传感器 II Abstract With the development of real estate, the building industry has also been a rapid development, and has formed a security industry. Building visual system belongs to one of the security products. Building video isa modern well-off residential service measures, it is mainly used in residential that can bea large area of the residential area and bea single building buildings housing. Building system use s voice technology, video technology, control technology puter technology to achieve owners and visitors of voice, video, and calls . It can be achieved by extending the release of information, control of home appliances, security alarm, audio and video functions. The graduation project use s the knowledge of analog electronics, digital electronics and EDA technology, sensors to achieve the basic functions of the design of the building visual system .T hese basic features includ e call features, visual function, function, the lock function and monitoring functions. This graduation design of the building system finishes basic calls, video , unlock the basic functions . What is more important, by extension itnot only can manage center management machine calls, help functions and host of management, but also by the expansion it gets other functions of the machine . It has better scalability and more extensive research space.
