The Design And Implementation Of Fire Information Monitoring System Based On ZigBee And Android

With the development of the technology of Internet of things,intelligent monitoring technology is becoming more and more important in people's daily life,and it is playing a more and more important role in the society.At present,the traditional monitoring technology can not meet the needs of users because of its passive,poor real-time,poor human-computer interaction and so on..Intelligent monitoring uses integrated wiring,advanced network communication,many nodes of sensor network and audio and video technology.the monitoring equipment interconnect together to build convenient unified monitoring network with high safety.All data will be uploaded to the cloud,and it will complete the storage and analysis of data in the cloud.the cloud interface is provided to all clients,therefore,it can download and display the data in a proper way.Based on the above background and the Science and Technology Department of Jilin Province key scientific and technological project,this paper designs a set of useful functions of the intelligent monitoring system,including the design and implementation of ZigBee wireless sensor network,Android mobile phone terminal development and related middleware.This system is divided into four parts: data acquisition,PC,server,Android mobile terminal design and implementation.At the part of data acquisition,the selection of fire information sensor and the extraction and processing of signal are realized,and the design established ZigBee wireless sensor network platform to ensure reliable and efficient data transmission.At the part of PC,PC is the middleware of ZigBee coordinator and cloud server communication,on the one hand,it interacts with sensor network and PC serial communication through the implementation of information,on the other hand,it implements information interaction with cloud server through the HTTP.At the part of the server,this system studies the client/server network framework and Linux kernel command line operation,it builds a cloud server configuration,network communication interface program and My SQL database,which ensures the public network data transmission reliable and stable.At the part of Android,this paper researches the Android network architecture,it achieves the real-time communication data from acquisition terminal toAndroid terminal by using JSON data exchange format.This paper studies on Multi threading programming to achieve the realization of APP related functions and researches network camera to complete the embedded app video monitoring.After the completion of the development of the various parts of the system,this paper makes the overall test of the system.The test results show that each module of the system is correct and reliable,the whole system is reasonable,and the function is thorough.
