基于GSM的远程门禁控制系统设计

介绍了应用GSM通信技术,开发基于单片机STC12C5A08S2的门禁控制系统。通过直流电机正反转按照调试好的圈数控制卷门的上下移动去实现控制,用户可以通过手机终端发送设定手机号码的短信查询门禁当前工作状态。门禁可手动自动切换：手动工作时,门可随意开关;当自动时用户可以发送带密码的短信到SIM卡去控制门的状态,在没有收到短信门却人为移动情况下,将通过外接的自动报警装置触发报警,同时向设定的手机号码发送短信。

Design of Remote Entrance Guard Control System Based on GSM

This paper describe a remote entrance guard control system which is based on GSM communication and STC12C5A08S2.The system reach control by the DC motor reversing with debugging laps moves up and down the rolling door,and user can though mobile terminal send setting SMS query current work status of entrance guard system.Entrance guard system can do manually and automatically switch：in manual status door can open and close as user＇s pleasure;in automatic status user can send SMS with password to control door status,if system do not receive SMS the door move artificially,though external automatic trigger alarm,at the same time system send SMS with setting phone number.
