Indoor Environment Monitoring System Based On ZigBee And Android Technology

Indoor environment is an important place for people to work,study and live.With the improvement of modern living standard,people have more and more strict requirements on indoor environment.Therefore,it has become an increasingly urgent need for people to monitor its safety and timely control the environment.With the rapid development of science and technology,the Technology of Internet of Things is becoming more and more mature.Wireless sensor network technology,wireless communication technology and automatic control technology have been integrated and applied to all aspects.In order to solve the problem of indoor environment monitoring,a system to monitor the environment safety,alarm the environment parameters beyond the warning range and locate the indoor faults accordingly is designed in this dissertation.Based on the traditional indoor environment monitoring,comprehensively analyzed the domestic and foreign development trends,various application scenarios and current market demands,a kind of indoor environment monitoring system based on the Android platform and ZigBee technology is designed in this dissertation for monitoring the most critical environmental parameters.The system is divided into three parts: data acquisition terminal,data processing terminal and mobile client.The main modules of the system are: anti-theft module,gas collection module,air temperature and humidity collection module,fire warning and fault location module.Based on ZigBee's powerful self-organizing network capability,users can select the required modules for free combination to meet their own needs.At the same time,the dissertation designed an APP as a mobile client.The APP,authenticated by ID,interacts with various terminal devices and transmits the collected environmental information in real time so that users can timely know indoor environmental conditions and make control.The APP can receive the data sent by the coordinator and update the APP interface data through the IP address Network embedded remote server.At last,the test of whether the desired function can be stably realized was completed in the studio.By comparing a large number of experimental data,it was shown that the system was stable and reliable,which could meet the requirements of real-time monitoring and control of daily indoor environment and has certain practical value.Figure [71] table [5] reference [55]...
