Design And Implementation Of Indoor Environmental Monitoring And Processing System

In the large indoor office environment,because of the limited transmitter power and building occlusion,and the coverage,the quality of network signals is not exactly the same,which makes users experience poorer when surfing in some areas.On the other hand,in some indoor places,because of the large number of equipments,it is very easy to have some dangers due to equipment aging,circuit shorted and other factors.In order to solve these problems,this thesis designs and implements an indoor environment monitoring and management system,which can simultaneously monitor and handle the situation of indoor network environment and physical environment;it can send mobile smart cars to enhance the intensity of network signal according to users’ signal enhancement service requests;and it can analyze whether there are potential safety probelms in the room according to the data collected by wireless sensor networks,the system will promptly notify therelated person if there are safety problems,and automatically send mobile smart cars to collect and return the real-time video information on the site.The system provides better network services and better security for indoor users.The main research contents and results are as follows:Aiming at the problem of data display,the system management platform and Android client are designed and implemented.and the functions of data visualization and page operation are completed,administrators can see the indoor environment imformation through system management platform directly;When an emergency occurs in the room,the platform will alert all indoor users and display live video information.Users are able to apply for network service request through the Android client APP to enhance signal intensity,so as to obtain a better online experience.Aiming at the data processing problem,the system server is designed and implemented.The functions of layer-to-layer communication,data analysis and processing,data storage and so on are completed.A data hierarchical storage system based on block chain is designed to solve the problem of data security storage.Using block chain and intelligent contract technology can completely preserve the core data of the system and ensure that the data is transparent,traceable,and irreversible.Zigbee sensor network and mobile agent are built for data acquisition.The Zigbee sensor network is placed in various locations indoors to collect environmental data from each location,and transmitting the data to the system server over a long distance through the gateway.The smart car receives the data information from the system server and executes the corresponding motion instructions,and the video information captured by the vehicle camera during the execution of the commands is sent back to the system management platform.
