高校实验室突发事件短信报警器的设计

摘要

在单片机开发板、GPRS MODEM、通用传感器的硬件基础上,应用AT指令开发方法,实现了实验室突发事件的感知,并向管理人员的手机发送报警短信、电话呼叫管理人员.实测表明,该设备报警距离不受限制,可实现远程监听和摇控,从而实现对实验室24h不间断监管,提高高校实验室安防管理水平.%The AT commands development method was used to achieve the perception of the laboratory incident based on microcontroller development board, GPRS MODEM and common sensor. It also can send alarm message and make phone calls to management personnel. Test shows that this device alarm distance is not restricted, and it can realize remote monitor and remote control, thus laboratory monitoring can be realized uninterruptedly for 24 hours, and the standard and efficiency of security management of labs could be improved significantly.
