摘要
针对职业院校实训室安全管理方式存在的不足,设计一种室内安防报警系统。该系统由两大部分构成:报警主控端和数据采集终端。系统设计结合两种无线技术:采集终端与主控端的通信采用2.4GHz无线通信,而主控端与远程用户的通信采用无线移动技术,GSM通信。系统实时采集门、窗、电的开关状态,当发生异常时,立即运行短信报警程序,将报警短信发送到实训室管理员手机,通知管理员室内异常情况,从而实现真正的智能安防。实验结果表明,该系统能达到预期的安防效果,具有一定实用意义。
Aiming at the disadvantages in security management of training room, designs an indoor security alarm system. The system is composed of two core modules: the main control alarm center and the data acquisition terminal. The system combines two wireless technologies: the com- munication of terminals and control center adopts NRF24L01 module, the communication of control center and remote user adopts wireless mobile technology. Real-time detects the switch state of door, window and electric brake, the system can automatically send SMS alarm pro- cedures to tell the manager the abnormal state when the indoor environment is abnormal. At the end, the system can achieve real intelligent security.
