基于物联网的实验室安防系统设计

Design of A Laboratory Security and Protection System Based on Internet of Things

为了适应中国高校多校区办学的发展趋势,解决实验室安防工作分散的问题。基于物联网三层架构,设计了一种实验室安防系统。感知层应用"GP32"MCU芯片实现了对实验室多种突发事件的检测;网络层应用"华为GTM900"GPRS MODEM传递报警信息和环境图像;应用层建设"云安防中心",集中受理不同校区实验室的事故报警,统一指挥、调配安防人员和装备。该系统能提高警情的响应效率,更加专业地处置特殊实验室的事故,及时控制事故危害和损失。

In order to support the develop ment trend of multi-campus operation of Chinese high education institutes and to solve the corresponding laboratory security problems caused by multi-campus operation, a laboratory security system is designed based on the three-layer structure of the Internet of things. At the perception layer, ＂GP32＂MCU chip is used to realize the detection of multi laboratory events; at the network layer, ＂Huawei GTM900＂ GPRS MODEM is used to transmit alarms and environmental images; at the application layer, a ＂cloud security centre＂ is established to deal with laboratory alarms of different campuses and deploy security personnel and equipments in a centralized manner. This system is helpful to improve the response efficiency, enhance the capability of settling special laboratory accidents, and control accident damage and loss timely.
