摘要
为了提高小区管理的数字智能化,设计了一种基于射频识别技术(RFID)和SIM800C的远程防盗智能门禁与安防系统。采用硬软件结合的方法,以STC89C52为控制核心,通过RFID读取用户的IC卡,利用SPI通信协议将IC卡号传输至上位机,以进行用户身份的核对与确认,验证通过后继电器开门。通过MQ-2烟雾传感器和HC-SR501热释电传感器获取烟雾浓度和非法用户闯入的信息。该系统以SIM800C进行无线通信,实现远程短信提示功能。调试结果表明,系统可在1 min内实现声光报警和防盗短信的远程监控,具有成本低、响应快、功能强的特点,有较强的实用价值。
In order to improve the digital intelligence of community management,a remote anti⁃theft intelligent access control and security system based on Radio Frequency Identification(RFID)technology and SIM800C is designed.Using the method of combining hardware and software,and STC89C52 MCU is used for the control core of system.The user’s IC card is read through RFID,and the IC card number is uploaded to the upper computer by SPI communication protocol to check and confirm the user’s identity.After verification,the door is opened by the relay.The smoke concentration and illegal user intrusion information is collected by the MQ-2 smoke sensor and HC-SR501 pyroelectric sensor,and wireless communication is carried out via SIM800C,which can realize the remote short message prompt function.The results indicate that the system can realize the audible and visual alarm and remote prompt of anti⁃theft short message within 1 min.It has the characteristics of low cost,fast response and strong function,which can have strong practical value.
