出入口门禁安全系统已成为现代安全防范系统中极其重要的一部分，在住宅小区、公司企业中的应用尤为广泛。本文突破以往的门禁系统模式，探讨一种新型的与电话网络结合使用的一种门禁管理系统。这种门禁控制系统主要针对来访者而设计，能够有效地对来访者进行管理，通过对其身份的识别可远程控制门禁开关。该门禁控制系统主要由计算机和门禁主控板两部分组成，计算机部分主要负责输出电话号码以及摘、挂机等信息，门禁主控板根据计算机传送过来的信息码进行相关的处理，如电话的呼叫以及摘、挂机等。本设计的最大特色之一就是利用已有的电话网络进行实时通信实现对门禁的控制，这大大增加了方案的可行性和可操作性。-Entrance access control security systems have become a modern security system, an extremely important part of the residential area, especially companies in a wide range of applications. In this paper, breaking the previous access control system mode, explore a new use with a telephone network access control system. This access control system is designed mainly for visitors, visitors can effectively manage their identity by identifying remote control access switch. The access control system consists of two main parts of a computer and access panels, computer part is mainly responsible for the output of a phone number as well as pick, hang up and other information, access control board based on information transmitted　the computer codes related to treatment, such as phone calls and pick, hang and so on. One of the most significant feature of this design is the use of existing telephone network to achieve real-time communication access control, which greatly increased the feasibility and
