【摘要】：近幾年隨著計(jì)算機(jī)技術(shù)及通信技術(shù)的發(fā)展,在物質(zhì)越來越豐富的今天人們對于財(cái)物安全有著更高的要求,中國已經(jīng)成為世界上僅次于美國的安防需求大國。門禁系統(tǒng)作為安防系統(tǒng)中的重要組成部分,人們對它的要求越來越高,安全性高、功能豐富、操作簡單、集成度高是時(shí)下門禁系統(tǒng)的主要發(fā)展方向。傳統(tǒng)的門禁系統(tǒng)立是基于識(shí)別技術(shù)和通信技術(shù)的出入口管制防護(hù)系統(tǒng),是一個(gè)偏向于控制的系統(tǒng),在當(dāng)下隨著應(yīng)用環(huán)境的擴(kuò)大、系統(tǒng)功能的擴(kuò)展,門禁系統(tǒng)越來越偏向于一個(gè)管理系統(tǒng)和控制系統(tǒng)的結(jié)合體,互聯(lián)網(wǎng)技術(shù)的引入使得它不再局限于地域空間的大小,識(shí)別技術(shù)的改進(jìn)使得它不再局限于近距離的單一的鑰匙開門或者刷卡開門方式。因此,探索一種新的識(shí)別方式、新的通信布局的門禁系統(tǒng)是很有意義的一個(gè)課題。本文在研究分析了傳統(tǒng)門禁系統(tǒng)的基礎(chǔ)上基于低功耗藍(lán)牙技術(shù)、輕量級TCP/IP協(xié)議棧和加密技術(shù)提出一個(gè)應(yīng)用于酒店環(huán)境的門禁系統(tǒng)方案。本課題研究的藍(lán)牙網(wǎng)絡(luò)化門禁系統(tǒng)主要功能是手機(jī)藍(lán)牙無線開門和網(wǎng)絡(luò)化,它分成三個(gè)部分分別是:控制器、服務(wù)器、智能手機(jī)。在控制器的硬件部分針對低功耗藍(lán)牙進(jìn)行了研究,選用芯片Nrf51822實(shí)現(xiàn)了藍(lán)牙數(shù)據(jù)的傳輸,與手機(jī)進(jìn)行對接;同時(shí)選用STM32F107作為微處理器,分析處理控制器的數(shù)據(jù)、完成串口和以太網(wǎng)通信�？刂破鞯能浖�設(shè)計(jì)主要包括主程序設(shè)計(jì)、建立在Lw IP協(xié)議棧上的以太網(wǎng)通信程序設(shè)計(jì)、建立在S110協(xié)議棧上的藍(lán)牙通信程序設(shè)計(jì)以及各種外圍的驅(qū)動(dòng)程序設(shè)計(jì)。智能手機(jī)部分研究了Android系統(tǒng)上的藍(lán)牙通信結(jié)構(gòu)、網(wǎng)絡(luò)通信結(jié)構(gòu)和重力感應(yīng)的接口函數(shù),實(shí)現(xiàn)了手機(jī)“搖一搖”認(rèn)證開門的功能和接收授權(quán)信息的功能。服務(wù)器端針對系統(tǒng)的數(shù)據(jù)傳輸、數(shù)據(jù)存儲(chǔ)和擴(kuò)展功能的需求,設(shè)計(jì)了對應(yīng)的數(shù)據(jù)庫表、Socket網(wǎng)絡(luò)通信和軟件界面。最后,對整個(gè)系統(tǒng)的功能進(jìn)行實(shí)驗(yàn)驗(yàn)證,重點(diǎn)對系統(tǒng)的網(wǎng)絡(luò)通信和藍(lán)牙通信的功能以及性能進(jìn)行了測試,并給出了具體的功能測試結(jié)果和部分實(shí)時(shí)性要求較高數(shù)據(jù)指令的響應(yīng)時(shí)間,發(fā)現(xiàn)系統(tǒng)的通信功能正常、響應(yīng)及時(shí)。測試的結(jié)果表明,藍(lán)牙網(wǎng)絡(luò)化門禁系統(tǒng)可以完成對酒店通道的有效管理和控制,并實(shí)現(xiàn)了網(wǎng)絡(luò)化和手機(jī)藍(lán)牙無線開門的功能。
[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.
