基于STM8L的门锁控制和状态识别

门禁系统是一种管理人员进出的数字化智能系统,可以实时监控门的状态和合法用户的进出状况,防止非法用户强制闯入。门禁系统作为智能家居系统的一部分,在现代安防领域发挥了巨大作用,也给用户的使用和管理带来了极大的便利性、高效性和安全性。本文介绍了利用具有超低功耗的STM8L微控制器为控制核心,设计了基于125KHz的射频读卡模块,采用EM4100系列ID卡作为用户身份识别卡,实现了对门锁的控制和状态的识别,并通过总线方式与服务器进行通信。实践表明,该系统整体功耗低、性能稳定、使用安全、管理方便。

Lock Control and State Recognition Based on STM8L

Gate-guarding system is a smart digital system which is used to control the access of people.It can monitor the state of the doors and the legal users in real time,and then prevents the illegal users breaking in the door.As part of the smart home furnishing sys-tem,the gate-guarding system plays an important role in modern security field,and it also brings convenience,effectiveness and safety to the using and administration of the users.This paper introduces a design using the ultra-low power STM8L microcontroller as the controlling center,and a 125 kHz radio frequency card reader module is implemented using EM4100 series ID card as user’s identity to control the lock and recognize the states,and the communication with the server is carried on through bus.The experiment results show that the system is low power consumption,stable in functioning,safe to use and easy to administrate.
