智能实验室远程无线安全报警控制系统设计与实现

Design and Implementation of Remote Wireless Security Alarm Control System for Intelligent Laboratory

实验室存放有各种实验器具,其中一大部分多存在安全隐患,特别是近年来实验室爆炸、火灾等事件频频发生,若不及时采取预防措施或在发生异常时发出警报,会造成较大的损失。在此背景下,开发人员为某高校的实验室设计了报警系统和应急疏散系统。首先,基于LabVIEW的虚拟仪器,结合声光报警器和感温感烟混合探测器等部件对该系统进行验算;其次,采用通用分组无线服务(General Packet Radio Service,GPRS)和ZigBee无线通信系统、网络通信技术的远程数据传输等远程调控技术;最后,利用A-Star算法设计当实验室各区域发生紧急情况时的最佳疏散路径。该系统具有成本低、功能完备、性能良好等优点,还可有效化解实验室危机,达到实时检测、及时控制以及紧急逃生的预期结果,提高实验室的安全性。

There are various kinds of laboratory instruments stored in the laboratory,and most of them have potential safety hazards,especially in recent years,when laboratory explosion,fire and other incidents occur frequently,if preventive measures are not taken in time or when abnormal alarm is issued,will cause greater losses.In view of the current situation,the alarm system and emergency evacuation system were designed and improved for a laboratory in a university.The virtual instrument based on LabVIEW,combined with sound and light alarms,temperature-sensing smoke detectors and other components,was used to verify the system;General Packet Radio Service(GPRS) and ZigBee wireless communication system,remote data transmission of network communication technology and other remote control technologies;using A-Star algorithm to design the best evacuation path in emergency situations in each area of the laboratory.The system has the advantages of low cost,complete functions,and good performance.Through this system,the laboratory crisis can be effectively resolved,and the results of real-time laboratory detection,timely control,and emergency escape can be achieved,and the safety of the laboratory can be improved.
