Design Of Laboratory Security Monitoring System Based On LabVIEW

As a carrier of experimental teaching,university laboratories are an important base for cultivating applied talents.The input and management level of university in laboratory construction determines the teaching level and scientific research strength of the university to a certain extent.Since the 21 st century,with the significant increase of China's national strength,the increasingly fierce competition in all walks of life,therefore,in order to enhance their own market competitiveness,job seekers put forward higher cultural and technical requirements,the community of high-quality The demand for application-oriented talent is also growing.Based on the above social status,colleges and universities to increase the experimental,practical teaching and investment in the degree of attention,the laboratory also will continue to expand the scale,the existing security facilities have been unable to meet the needs of most laboratories,a variety of security risks have been Has become the laboratory daily management problems to be solved.Therefore,the laboratory needs a stable and reliable security system to conduct real-time and effective monitoring,so that managers in the first time to find abnormal circumstances in order to take timely and effective response measures to ensure that laboratory equipment and laboratory personnel safety,Does not affect the normal teaching and scientific research work carried out.From the current situation,the major colleges and universities of the laboratory security monitoring system is the way most of the wired network sensors to collect information,data transmission,although it has a stable and reliable,more complete data collection and other advantages,But the inadequacies of the installation is complicated,the installation of monitoring systems require specialized wiring,resulting in line clutter,easy to organize.As the traditional monitoring system expansibility and poor mobility,so its lack of universal adaptability.In the monitoring software,because of the existing monitoring software is simple,low degree of automation,need to rely on artificial judgments alarm,which monitors the quality of their own very high demands,leading to monitoring system accuracy and real-time difficult Guarantee.In view of the above shortcomings,this paper designed a LabVIEW graphical language based on the laboratory security monitoring system.In this paper,the hardware design and system software design,respectively,introduced the LabVIEW graphical language based on the laboratory security monitoring system.The system is a distributed architecture,by the ZigBee coordinator,theenvironmental parameters function module,GSM SMS alarm module and run on the laboratory management personnel monitoring terminal host computer processing software,the laboratory can be the security situation and temperature,Humidity and combustible gas content of real-time monitoring,environmental monitoring data by the ZigBee wireless network and USB interface to upload to the laboratory supervisor's monitoring terminal,the host computer to read the relevant data and analysis and through the host computer interactive interface Showing the monitoring information,so that real-time monitoring of management.In the event of fire,gas leaks and other emergencies,the system through the GSM SMS alarm module to the laboratory management personnel to send mobile terminal alarm information,so that managers can be the first time to detect abnormalities in the monitoring point and take timely and effective Measures to control the danger.The laboratory security monitoring system designed in this paper is proved to be stable and reliable in operation,low in installation cost,simple in hardware structure,strong in adaptability,expandable in space and high in intelligence.It can be applied to the lab environment of most schools at present.As well as other small-scale security monitoring environment.
