Research And Design Of Smart Home Remote Monitoring System Based On Wireless Sensor Network

With the high popularity of smartphones, the rapid development of mobilecommunication technology, people’s quality of life and security consciousness unceasingenhancement, the increasing demand for smart home system. In this paper, all kinds ofwireless sensor network technology and wireless communication technology were analyzed,and put forward a kind of smart home remote monitoring system based on wireless sensornetwork (WSN) solution，Implemented by the user’s mobile phone to remote monitoringhome electric equipment.At first, this paper gives the overall architecture of smart home remote monitoringsystem, with STM32F103chips as the main controller of smart home system, rf modulesCC1110as home wireless sensor network communication nodes, these nodes by SimpliciTInetwork protocol together, forming a small family LAN. Then combined with GPRSwireless communication technology and Web technology, the node is connected to theremote server, with users of mobile terminal to access, can form a wireless remotemonitoring system. And then respectively from two aspects of hardware design and softwaredesign of the smart home system. Hardware design mainly includes the choice of maincontroller and the design of the node, focus on terminal sensor CC1110and GPRS wirelesscommunication module SIM900A hardware schematic design. Software design from thefunctional requirements, the overall framework design and implement three parts to thedesign of the system software in detail. The last to complete various functions of the systemtest.This innovative: the design of the intelligent household in the design of wireless sensornetwork (WSN) using a low power consumption, low cost, strong ability to penetrate wallsof high-frequency modules CC1110, and transplanted the SimpliciTI network protocol; Usethe RT-Thread small embedded real-time system as intelligent household main controller ofthe operating system; Through the Web server as remote data storage and transfer platform,solved the GPRS module and the remote wireless communication problem on user’s phone.This article main research content:1. Based on wireless sensor network technology, GPRS/GSM technology, embeddedsystem technology, the Android system technology, such as computer software technology, Implements a smart home remote monitoring system based on wireless sensor network.2. According to the requirements of the smart home remote wireless monitoring systemdesign, system overall design scheme is studied. Including wireless local area network, theremote Web server and the user smartphone monitoring system design for the client.3. Research on the hardware system design, including rf wireless communicationmodule of CC1110, STM32F103host module and GPRS remote communication module ofhardware circuit design.4. A wireless local area network (wlan) was studied based on the SimpliciTI networkprotocol software system design, including the main controller module, the center nodemodule, terminal node module and extended module of software architecture design.5. Wireless LAN heartbeat packets detection method research and design.includingperipheral node module and the center of heartbeat packets testing module design.6. The remote server basic design framework based on Web technology. Has realized theterminal nodes of the wireless local area network (wlan) module to the remote serverthrough GPRS wireless gateway function to upload pictures, and user via mobile phone canrealize the function of remote viewing home picture.
