Design And Implement Of Wireless Network Remote Monitoring Device Based On Android

Remote monitoring has been the research focus in the field of industrial control,agricultural modernization, environment monitoring and so on. The past researchmainly concentrated to monitor remote object to use cable network. In practice, thissystem exposes some shortcomings, such as advance into the huge, field wiringdifficulties, extended compatible ability is not strong and so on. With the developmentof technology, people have entered the mobile Internet era, Internet equipment is nolonger confined to the personal computer, workstation and mainframe computers.Mobile internet terminal handset constantly upgrading, more compact, more feature-rich,faster development direction. Android mobile internet terminal is one of the typicalrepresentative, Android is designed based on the Linux operating system for mobileInternet development, has the rich network data connection. Under this background,research and development of wireless network monitoring device based on Android, canovercome the shortcomings of traditional monitoring terminal, its light and flexible, nogeographical restrictions advantage.In order to implement the wireless network monitoring function, this paper dividesthe system into three parts. Upload sensor terminal, WEB sensor access platform,Android system terminal.In this paper, a detailed analysis of the Android architecture and its applicationmethod in mobile Internet environment, build Android system application developmentplatform. Analysis of the structure of the sensor WEB platform based on MySQL, PHPand Apache. Study of3G, WiFi, ZigBee wireless network communication standard,analyzes their application in the field of monitoring, and using3G and WiFi as thecommunication mode. The design uses AVR microcontroller ATmega328as the core ofthe ArduinoUno control board and EthernetShield network expansion modules as dataacquisition terminal. Build the acquisition hardware platform, the terminal software,realize the detection of temperature and humidity of the environment, through theInternet to upload data to the WEB monitoring platform.In the experiments, the API interface public sensor access platform, using AVRArduinoUno development board as the sensor terminal board, writing program torealize communication with WEB server, upload sensor data. Design Androidapplication program, and install on the Android intelligent mobile phone, the mobile phone in the3G and WiFi network environment, can realize the query of sensor datawhich on ArduinoUno control panel and WEB data monitoring platform.
