【摘要】：随着嵌入式、数据库、指纹自动识别等技术的迅速发展，电子工程业也迅速发展起来，在适应信息化得发展的同时，多种技术综合应用的工程技术，将人们工作效率提到了一个新的台阶。由于新技术的众多优越性，，使得人们对于现代化的办公和生活场所的安全，提出了更高的要求，传统的门锁系统以及手工管理，已经远远落后于当代人们的实际需要，随着计算机和通信网络的进步，人们开始开创了一个安防智能化以及网络化的时代，同时为了推进智能楼宇以及智能小区的快速发展，现在的门禁系统同样需要必须与时俱进，采用更可靠更安全的系统。本文根据企业的实际需要，综合利用多种技术，设计实现了一个全新类型的门禁系统。这个门禁系统在设计的时候，采用了多种新思想，各个部分设计时采用了模块化技术，在前端用基于ARM9S3C2410的嵌入式系统完成指纹识别前端的信息采集，然后通过基于TCP/IP协议的网络上完成与核心服务器端的信息的传输，在核心服务器中用数据库技术管理门禁系统相关数据信息，整个门禁系统由于采用了网络协议，可移植性增加，方便企业迁移等事宜。根据门禁系统功能要求结合实际应用，我们采用ARM9S3C2410做硬件基础，并在其基础之上设计实现了满足硬件需求的的架构，并详细研究修改硬件操作系统Linx中的一些问题，设计了适应于该平台的引导程序。根据硬件接口特性，实现了集成指纹图像捕捉传递等功能于一体的指纹识别前端。最后，对于系统的通信方式，我们设计了一个新的通信协议，由于这个协议时基于TCP/IP的，在设计协议的时候我们还设计了相关命令，以此为基础，我们最终设计实现企业门禁系统管理软件。
[Abstract]:With the rapid development of embedded database fingerprint automatic identification and other technologies the electronic engineering industry has also developed rapidly. The efficiency of people's work has been brought to a new level. Because of the advantages of the new technology, people put forward higher requirements for the security of modern office and living place, traditional door lock system and manual management. Has fallen far behind the actual needs of contemporary people, with the progress of computer and communication network, people began to create a security intelligent and networked era. At the same time, in order to promote the rapid development of intelligent buildings and intelligent residential areas, the current access control system also needs to keep pace with the times and adopt a more reliable and secure system. In this paper, according to the actual needs of enterprises, comprehensive use of a variety of technologies, the design and implementation of a new type of access control system in the design, the use of a variety of new ideas. Each part of the design uses modular technology, in the front end of the embedded system based on ARM9S3C2410 to complete fingerprint recognition front-end information collection. Then through the network based on TCP/IP protocol to complete the transmission of information with the core server, in the core server using database technology to manage the access control system related data information. Because of the adoption of network protocol, the whole access control system increases portability and facilitates enterprise migration. According to the functional requirements of the access control system combined with practical applications, we use ARM9S3C2410 as the hardware basis, and on the basis of the design and implementation of the architecture to meet the hardware requirements. Some problems in modifying the hardware operating system Linx are studied in detail, and a bootstrap program suitable for this platform is designed, according to the characteristics of the hardware interface. The fingerprint recognition front end which integrates the functions of fingerprint image capture and transfer is realized. Finally, for the communication mode of the system, we design a new communication protocol, because this protocol is based on TCP/IP, we also design the relevant commands when designing the protocol, which is the basis. We finally design and implement the management software of the enterprise access control system.
