新疆哈密门禁系统之指纹门禁系统组成

Composition of fingerprint access control system

指纹门禁体系的硬件首要由微处理器、指纹辨认 模块、液晶闪现模块、键盘、实时时钟/日历芯片、电控锁和电源等组成。微处理器作为体系的上位机，操控整个体系。指纹辨认模块首要完毕指纹特征的搜集、比对、存储、删去等功用。液晶闪现模块用于闪现开门记载、实时时钟和操作提示等信息，和键盘一起组成人机界面。

The hardware of fingerprint access control system is mainly composed of microprocessor, fingerprint identification module, LCD module, keyboard, real-time clock / calendar chip, electronic lock and power supply. As the upper computer of the system, the microprocessor controls the whole system. Fingerprint identification module mainly completes the collection, comparison, storage, deletion and other functions of fingerprint features. The LCD module is used to display the information of door opening record, real-time clock and operation prompt, and forms the human-machine interface with the keyboard.

按体系功用，软件首要由指纹处理模块、液晶闪现模块、实时时钟模块和键盘扫描模块等组成。指纹处理模块首要担任微处理器与指纹辨认模块之间指令和回来代码的信息处理；液晶闪现模块依据液晶闪现模块的时序，编写驱动程序，以结束闪现汉字、字符的目的；实时时钟模块依据时钟芯片的时序，编写通讯程序．结束对时钟芯片的读写操作；键盘扫描模块就是依据键盘的规划原理编写键盘程序来辨认有无按键动作和按下键的键号。

According to the system function, the software is mainly composed of fingerprint processing module, LCD module, real-time clock module and keyboard scanning module. The fingerprint processing module is mainly responsible for the information processing of commands and return codes between the microprocessor and fingerprint identification module; the LCD module compiles the driver program according to the timing of the LCD module to realize the purpose of displaying Chinese characters and characters; the real-time clock module compiles the communication program according to the timing of the clock chip to realize the reading and writing operation of the clock chip; the keyboard scanning module Block is to write a keyboard program according to the design principle of the keyboard to identify whether there is a key action and press the key number.

按操作流程，软件首要由指纹开门程序、指纹处理程序、暗码处理程序和体系设置程序四部分组成。其间指纹处理、暗码处理和体系设置三部分只有处理员才有此权限。指纹处理程序由挂号指纹模板程序、删去指纹模板程序、清空指纹模板程序和阅读开门记载程序四部分组成；暗码处理程序由暗码修正程序和暗码开门程序两部分组成；体系设置程序由时刻设置程序和日期设置程序两部分组成。

According to the operation process, the software is mainly composed of fingerprint door opening program, fingerprint management program, password management program and system setting program. Among them, fingerprint management, password management and system settings are three parts. Only administrators have this permission. The fingerprint management program consists of four parts: registering fingerprint template program, deleting fingerprint template program, clearing fingerprint template program and browsing door opening record program; password management program is composed of password modification program and password opening program; system setting program is composed of time setting program and date setting program.
