基于网络的指纹门禁系统数据传输接口

A Design of Net Transmission Interface of Fingerprint Access Control System Based on Web

本文对企业内部基于网络的多用户指纹门禁系统的指纹识别仪的硬件结构进行了简要介绍,同时着重介绍了客户端与服务器之间的指纹信息以及确认信息的通信问题的一种解决方案:主要使用Ubicom公司的通讯控制器SX52,以及Relteck公司的以太网控制器RTL8019AS构成了完成既能与指纹图像采集处理模块进行串行通信,又能与远端服务器进行基于TCP/IP协议的网络通讯的智能模块。同时介绍了专用于该系统的自定义应用协议FITP。

This paper briefly introduces the hard structure of multi-user fingerprint access control system based on enterprise LAN. The solution to the communication problem of fingerprint image and affirmance information between client and server is mainly discussed. It mainly uses the communication controller SX52 of Ubicom and Ethernet controller RTL8019AS of Relteck to construct an intelligent block, which could realize both the serial communication with fingerprint image collecting and processing block and net communication based on TCP/IP with remote server. FITP, the self-defining application protocol especially for this system is also introduced.
