Design And Implementation Of Smart Home System Based On Zigbee Wireless Network

Through the adoption of related technologies, e.g., network communication, automatic control, audio and video, sensor technology, smart home can be seen as hardware facilities associated with furniture life, which is integrated by residential, and a management system related to the family’s daily life. It can enhance the safety of home furnishing, as well as convenience and comfort, and form a residential environment with the environmental protection and energy saving. Smart home, by using network communication and technology of the Internet of things, connect all various devices in the home and provide a variety of functions, such as a household electrical appliance control, lighting control, curtain control, security control, environmental monitoring, HVAC control. To realize the control and unified management of household electrical appliances, this paper constructs the communication network of smart home through the use of WIFI communication, ZigBee network, VPN, infrared remote control, sensorautomatic control technology, the center of the control server and the nodes of different control modules. The main contents of this paper include:(1)Through the technology of the infrared remote control, ZigBee network, VPN, sensor and the Internet, and a comprehensive analysis of the present smart homes, this paper proposes a set of solutions, which not only meet user needs, but also have relatively low cost.(2)Learning the technology of ZigBee, making full use of the CC2530 network, achievinginfrared remote control device and docking of the server by infrared learning technology, and data transmission of server and equipment by the use of CC2530 chip.(3)Design infrared learning module and take infrared remote control functions together by using WIFI omni directional IR learning module based WEB.(4)The design of power conversion modules.(5)Design of temperature sensor module and use 18B20 temperature sensor, realizing the detection of the indoor temperature by connecting transmits data to the terminal to. Design of air quality detection module and use M205 air quality sensor as the end. Its test data can transmitted to the control server by CC2530, and then users can timely understand of the situation of indoor air.When indoor air quality reduces to a certain standard, set the alarm mode. Design of the gas detection module and detect indoor gas by the sensitivity of the MQ-5 gas sensor. When the gas content exceeds a certain standard, the real-time alarm notifies the user.(6)Design of lighting control module and control the lights out by driving the relay based the CC2530 data output pin level.
