【摘要】：近几年随着计算机技术及通信技术的发展,在物质越来越丰富的今天人们对于财物安全有着更高的要求,中国已经成为世界上仅次于美国的安防需求大国。门禁系统作为安防系统中的重要组成部分,人们对它的要求越来越高,安全性高、功能丰富、操作简单、集成度高是时下门禁系统的主要发展方向。传统的门禁系统立是基于识别技术和通信技术的出入口管制防护系统,是一个偏向于控制的系统,在当下随着应用环境的扩大、系统功能的扩展,门禁系统越来越偏向于一个管理系统和控制系统的结合体,互联网技术的引入使得它不再局限于地域空间的大小,识别技术的改进使得它不再局限于近距离的单一的钥匙开门或者刷卡开门方式。因此,探索一种新的识别方式、新的通信布局的门禁系统是很有意义的一个课题。本文在研究分析了传统门禁系统的基础上基于低功耗蓝牙技术、轻量级TCP/IP协议栈和加密技术提出一个应用于酒店环境的门禁系统方案。本课题研究的蓝牙网络化门禁系统主要功能是手机蓝牙无线开门和网络化,它分成三个部分分别是:控制器、服务器、智能手机。在控制器的硬件部分针对低功耗蓝牙进行了研究,选用芯片Nrf51822实现了蓝牙数据的传输,与手机进行对接;同时选用STM32F107作为微处理器,分析处理控制器的数据、完成串口和以太网通信。控制器的软件设计主要包括主程序设计、建立在Lw IP协议栈上的以太网通信程序设计、建立在S110协议栈上的蓝牙通信程序设计以及各种外围的驱动程序设计。智能手机部分研究了Android系统上的蓝牙通信结构、网络通信结构和重力感应的接口函数,实现了手机“摇一摇”认证开门的功能和接收授权信息的功能。服务器端针对系统的数据传输、数据存储和扩展功能的需求,设计了对应的数据库表、Socket网络通信和软件界面。最后,对整个系统的功能进行实验验证,重点对系统的网络通信和蓝牙通信的功能以及性能进行了测试,并给出了具体的功能测试结果和部分实时性要求较高数据指令的响应时间,发现系统的通信功能正常、响应及时。测试的结果表明,蓝牙网络化门禁系统可以完成对酒店通道的有效管理和控制,并实现了网络化和手机蓝牙无线开门的功能。
[Abstract]:In recent years, with the rapid development of computer technology and communication technology, more and more rich people in the material today have higher requirements for safety of property, Chinese has become the world behind the United States security needs of the country. The access control system is an important part in security system, it requires more and more of. High safety, abundant function, simple operation, high degree of integration is the main development direction of the access control system. Traditional access control systems are recognition technology and communication technology, access control protection system based on a bias in the control system, in the moment with the expansion of application environment, expand the function of the system, access control system more and more biased in favor of a combination of management system and control system, the introduction of Internet technology makes it no longer confined to the geographical space size, improved recognition technology makes it no longer Limited to close a single key or credit card to open the door. Therefore, to explore a new way of identification, access control system of the new communication layout is a topic of great significance. In this paper, based on analyzing the traditional access control system with low power consumption based on Bluetooth technology, access control system scheme of lightweight TCP/IP protocol stack and encryption technology to put forward an application in the hotel environment. The main function of Bluetooth network access control system of this thesis is to open the door and mobile phone Bluetooth wireless network, it is divided into three parts namely: controller, server, intelligent mobile phone. In the hardware part of the low power Bluetooth was studied, using Nrf51822 chip the Bluetooth data transmission, mobile phone and docking; at the same time using STM32F107 as the microprocessor, analysis of data processing unit, complete serial port and Ethernet communication control. The software design of the system includes the main program design, the Ethernet communication program design based on Lw IP protocol stack, based on S110 protocol stack of Bluetooth communication program design and various peripheral driver design. Part of the intelligent mobile phone Bluetooth communication structure of the Android system, interface function of network communication structure and gravity induction the realization of the mobile phone "shake" to open the door of the authentication function and receiving authorization information. The server for data transmission system, data storage and extension needs to design a data base table corresponding to the Socket network communication and software interface. Finally, experiments are carried out to verify the function of the whole system, the key the system of network communication and Bluetooth communication function and performance test, and gives the function of specific test results and some real-time requirements higher according to instructions The response time shows that the communication function of the system is normal and the response is timely. The test results show that the Bluetooth network access control system can effectively manage and control the hotel passageway, and realize the function of networking and mobile phone Bluetooth wireless opening.
