The Research And Implementation Of Integrated Analysis System Of Cabin Fire Parameters

From the point of view of fire parameter analysis system,this paper shows the progress made in the field of fire detection in the past decades.At the same time,compared with the classic fire detection system,the fire parameter analysis system designed by us has made some changes in the data collection,data analysis and fusion,secondary analysis and the corresponding measures with the combination of data.The overall design is more humanized than the traditional detection and prevention system,and the operation is more convenient.In other words,this is a fire parameter analysis system which is upgraded from inside to outside.This design is divided into two parts: data acquisition terminal and data receiving terminal in hardware configuration.The data acquisition terminal drives the temperature,pressure,wind speed and thermal radiation sensors by single chip microcomputer.The collected data is transmitted to the PC terminal of the host computer through RS485.The upper computer data receiving terminal consists of central integrated monitoring station,cabin fire parameters integration analysis system software and large screen LCD display system.The software part of it is the hard core of my work.According to the functional requirements and actual implementation,the function of the software includes: displaying the real-time data of the test points,drawing all kinds of data into a line diagram,displaying the location of the sensor,generating the temperature field cloud chart,determining the size and risk coefficient of the fire,and some basic storage and control functions.In these functions,the algorithm design of temperature field nephogram is an important innovation in this paper.This system combines a variety of sensor data information to integrate the characteristics of various kinds of data in the case of fire.According to such characteristics,the threshold is designed,and the accuracy of fire detection is greatly improved.And the system has certain upgrading space,and has broad application prospects in fire detection field.
