Abstract
|
With the development of modern technology and the improvement of living standard,people bring forth a higher demand on the residential environment, thus the traditional solutionshaven’t met people’s urgent needs. So the paper proposes a method which focuses on a set ofliving and security residential environment to solve this problem, which has had a significance toimprove the applications of the smart home.Based on Cortex-M3 microcontroller and nRF24L01 radio chip, the paper designs a remotecontrol system on smart home which is used to monitor the devices’ state. Among them, thecomputer network technology provides the interactive interface for remote communication;Radio Frequency Identification (RFID) provides the middleware security for setting up thefamily network. Finally, implement the design of smart home remote control system based onthese technologies. The main work and achievements are as follows:1 .This paper analyses the overall architecture and networking of smart home systemnetwork. To target the technique used for the design, establishes a plan that the embeddedcontrol server is set up as the core of home control. At last the author completes the hardwaredesign of smart home system based on the functional unit.2. In order to monitor and control the system through the PC, the advanced web technologyAjax is applied, which combines with CGI program and web pages, managed to refresh the partsof information in web, achieve the features that information can be interacted between the userand the interface.3. On the basis of the design of functional modularity, this paper uses the Cortex-M3 ARMmicrocontroller as the platform, and transplants the uIP protocol and the FatFs software modulein embedded operating system.4. According to the design patterns of CEBus protocols, the paper proposes and completes aprotocol communication model which treats the record as a unit in family network and uses thenRF24L01 RF unit as the carrier. It proves that the design patterns own a good result in practiceand can significantly improve the communication efficiency.5. This paper presents a method that utilizes the content of controller to establish a mapping state of terminal equipment, and then improves every unit of home control system, including thelight control subsystem, temperature query subsystem, infrared detection subsystem and alarmsubsystem.Ultimately, it proves that the smart home control system achieves the desired goals. It candirectly and efficiently control the terminal equipment through the network, and the system hasgood real-time performce, high efficiency and low cost etc., which has a high value.
