The Research And Practice Of Fire Alarm Network Platform Based On Protocol Intelligent Analysis

Automatic fire alarm system plays a very important role in fire prevention.Withthe wide using of the automatic fire alarm system,the demands of fire unit on rapidlocating,timely and accurate obtaining the fire alarm information and networkmonitoring,are more and more obvious.However,the traditional automatic fire alarmsystem operates complexly,causing the fire alarm location cannot be timely andaccurate found.Because there is no uniform standard of alarm communication protocolbetween different manufacturers,it brights difficulty to network monitoring.If thedifferent communication protocol of automatic fire alarm systems can be put into aunified management platform,realizing network management and can timely get alarminformation and quickly locate alarm position,it is not only beneficial to the fire unitsof automatic fire alarm system for global and real-time monitoring andmanagement,but also conducive to improve the management level and efficiency offire units, reducing the manpower and resources cost.According to the analysis of communication protocols,this paper presents amethod of protocol intelligent analysis.The method includes communicationprotocol grammar extraction and behavior semantic association,using dynamicprotocol tracing method to resolute protocol data and grammatical informationextraction.Finally,the combination of syntax and semantic analysis,this method canrealize the communication protocol of the crack.In addition,through the analysisof automatic alarm system present situation and the demand for a university Qingdaocampus,this paper also puts forward a design scheme of integrated set of software andhardware and realizes a fire alarm network platform.The different brands and differentmanufacturers of automatic fire alarm system can be incorporated into the unifiedmanagement platform. Through online or offline map way,the fire alarm information ispresented in the specific alarm position, realizing the visualization of locationinformation of fire alarm.Network platform uses Flex,PHP and MySQL as thefront-end development tools,C#language and TCP/IP protocol for server development tool,using Google cloud services platform for the map.The platform is successfullyapplied in Colleges and universities, and achieves good results.
