摘　　要：针对电脑开机密码容易遗忘或被破解情况,设计一种需要身份认证的新型开关控制系统,主要通过STC12C5A60S2单片机来控制AS608模块匹配指纹进行身份认证,认证通过则控制JQC-3FF继电器导通从而使电脑正常通电,并辅以液晶显示、声音提示等功能。此外提出一种通过简单按键对指纹录入和删除等功能进行权限设置的算法,确保指纹模板库不被随意更改。系统测试表明,该系统能有效控制开关的导通,功耗低,高效准确。In view of the situation that the computer boot password is easy to be forgotten or cracked,a new switch control system which needs identi⁃ty authentication is designed.The AS608 module is controlled by STC12C5A60S2 microcontroller to match the fingerprint for identity au⁃thentication,and JQC-3FF relay is controlled to turn on when the authentication is passed,so that the computer can be powered on nor⁃mally,supplemented by LCD display,voice prompt and other functions.In addition,proposes an algorithm to set the authority of finger⁃print input and deletion by simply pressing the key to ensure that the fingerprint template library is not changed at will.System test shows that the system can effectively control the switch conduction,with low power consumption,high efficiency and accuracy.
