非可视楼宇对讲系统的研究（硬件部分） Non-visual intercom system for buildings （Hardware part） 表 格 16 个 插 图 17 幅 摘要 非可视楼宇对讲系统是为了方便小区的管理而设计的一种对讲体系。当有来访者时，来访者可通过在门口机上输入某个房号，来达到呼叫此住户的目的，然后，访客在得到住户的开锁许可后方可进入。此外，住户进入小区时，可以在门口机上输入事先设定的开锁密码来实现自动开门。系统主要采用单片机控制实现电路功能，充分运用万能编码原理实现各户与主机之间的对应关系，既方便、又是更加的人性化，将音频放大电路、通话电路、数显电路等一些基本电路组合起来，主要的复杂功能通过各种主要芯片来实现。最终达到为小区住户提供既快捷方便，又安全的管理服务，实现小区住户的高效智能管理。 关键词：对讲系统 开锁 管理服务 单片机控制 智能管理 Abstract Building non-visual intercom system is to facilitate the management of residential intercom systems designed for a kind of intercom system. When a visitor coming, Visitors can enter the plane at the gate to a room number to achieve the purpose of calling this household.Then visitors are unlocking the tenants permission before entering. In addition, When residents enter the cell，they can enter the plane at the gate prior to set password for automatic door unlocking. System is mainly for the residential tenants quick and easy, and secure management services. Intelligent management to achieve efficient cell.System is mainly achieved using microprocessor controlled circuit function, universal coding theory to achieve full use of the household and the correspondence between the host, is convenient, it is more humanized, the audio amplifier circuit, the call circuits, digital circuits, the basic circuit together, the main function of the complexity of the major chip achieved through. For the residential tenants ultimately both quick and easy, and secure management services, to achieve efficient intelligent management of district residents. Key Words: Intercom Systems; unlocking; Management Services; microprocessor controlled; intelligent management 目 录 摘要 1 ABSTRACT Ⅱ 第一章 引言及芯片说明 1 1.1非可视对讲系统简介 1 1.2各类主要芯片功能说明 1 1.2.1 BPC1136芯片功能简介 1 1.2.2 MC34018芯片简介 14 1.2.3 ULN2003芯片简介 15 第二章 楼宇对讲系统中各项功能电路的分析 20 2.1 楼宇系统设计简介 20 2.2 12V直流电源设计 20 2.3 单喇叭分机原理图设计 20 2.4译码器电路原理图设计 21 2.5 密码开锁及分机开锁功能 22 2.5.1 密码开锁 22 2.5.2分机开锁 22 2.6主/分机音乐功能 23 2.7主机和分机通话控
