摘 要

安防系统由视频监控系统、门禁系统、探测报警系统等组成，广泛运用在社会和家庭中。本课题以门禁系统为出发点，进行无线门禁系统的研究。

在现有的门禁的系统中，各个部分的距离一般不超过20米，则可以使用中短距离无线技术将系统中的各部分进行无线连接。对比中短距离无线技术（蓝牙、ZigBee、WiFi），选择出最适合系统的技术。蓝牙4.0中提出了低功耗蓝牙技术（BLE），在功耗上有较大的提升，同时在其他性能上也不弱于其他无线技术。选择BLE作为实现门禁系统无线化的标准。

TI CC2540、Nordic nRF51822、Dialog DA14580都能支持低功耗蓝牙技术。在这三个硬件方案中，认为DA14580在性能上不输于其他两个，尤其在功耗处理有极大的优势。安卓手机在4.3版本以后就支持低功耗蓝牙技术，将手机作为系统终端加入进来，为了使手机与蓝牙模块通信，用eclipse平台开发了一款APP，用该软件连接蓝牙模块同时进行信息传输。

智能手机作为物联网的关键钥匙，可以将系统运用物联网技术，增加更多的物联设备，使得系统功能齐全、智能、便利等，当然这是后续的工作。

Research on Wireless Micro Intelligent Terminal

Abstract

Security systems are now widely used, such as residential, bank, attractions and other public places.Security system consists of video surveillance systems, access control systems, detection and alarm systems and other components.The issue with the access control system as a starting point, wireless access control system research.

In the existing access control systems, short-range wireless technology in use in various parts of the system to connect wirelessly.The short-range wireless technology (Bluetooth, ZigBee, WiFi) performance comparison, choose the most suitable system technology.Bluetooth 4.0 low-power Bluetooth technology is proposed, there is a larger increase in power consumption, while the other properties are not weaker than other wireless technologies.

TI CC2540, Nordic nRF51822, Dialog DA14580 can support low-power Bluetooth technology.In these three hardware programs that DA14580 the performance is not lost on the other two, especially in the power processing have great advantages.Android phones version 4.3 will support future low-power Bluetooth technology, the mobile phone as the system terminal to join in, in order to communicate with a Bluetooth phone module, developed an APP, connected with the Bluetooth module software to transmit information at the same time.

Smartphone as a key key things, you can use the system of Things technology, adding more things together equipment, making the system fully functional, intelligent, convenient, of course, this is the follow-up work.

第一章 绪论

1.1 安防系统的研究现状和挑战

安全防范是为了让自己的人身安全和财产得到保护，免于盗窃，火灾，暴力破坏。安全是我们的目的，防范只是手段，希望通过防范达到安全的目的。安全防范可以说是由物防，人防，技防三部分组成。本课题主要讲的安防系统属于技防的范畴。

安防系统运用技术防范产品与设备及其相关的电子，微机，光电，网络等产品与设备组成的光电系统。它主要包括梯控系统，门禁系统，探测报警系统，视频监控系统，消费系统，停车场系统等。大部分的安防系统主要是由视频监控，探测报警，门禁三部分组成。

视频监控是安防系统中一个重要组成部分，用闭路电视的方法对要监控的地方进行图形和声音的监视，并可实现图形的切换，分割，存储，跟踪和报警等，是一种先进的，防范能力强大的综合系统。它可遥控摄像头观察监控地方的一切情况，同时将观察的图形和声音发送到监控中心，并用存储设备记录下来，为日后某些情况的处理或公安部门处理案件提供便利及相关的证据。

探测报警是来探测自然环境中各种行为或人为造成的各种行为的报警系统。当系统在运行时，外界出现不正常的行动，迅速发出报警信号。
