The Research Of WebSocket Home Intelligent Gateway With Real-time Characteristic

With the rapid development of network and intelligent home technology and in-depth applications, intelligent home is the inevitable trend of future development of home field,towards the direction of network, informatization, intelligent direction.The effect factor of intelligent home development is intelligent home gateway. The intelligent home gateway with intelligent control hub function, at present, always use HTTP connection on the market,which the real-time is insufficient. Therefore, based on the existing common gateway polling and Comet real-time communication technology, WebSocket intelligent home gateway design method based on WAMP environment, supporting for Web,and with good real-time performance was presented.Based on the WAMP environment,the intelligent home gateway WebSocket protocol architecture control system scheme based on Arduino Yun platform.was designed. the part of the hardware design of gateway based on Arduino Yun development board makes use of hardware interface of Arduino Yun open platform to connect peripheral sensing circuit,home equipment and control circuit, and construct intelligent system. In the same family environment, the remote real-time control and the real-time collection and monitoring of sensor data of intelligent home equipment terminal were realized. Based on RPC and PUB/SUB message transmission mode in WAMP protocol, message transmission between the gateway and the server and the home equipment message were realized, home intelligent gateway demand analysis of message transmission was completed. Through full duplex real-time communication of WebSocket, real-time effective control and management of intelligent home equipment was realized, providing end users with user interface in the mobile devices with Web browser and mobile phone APP interface and can be easily converted to control intelligent devices via a custom protocol.The message format applying to intelligent home gateway was presented, and the intelligent home gateway message formats to meet design was customized: JavaScript Object Notation(JSON) message format with simple, fast, effective data analysis and logical processing characteristics, enhancing the gateway real-time. Based on Crossbar Router cloud and 4G LTE mobile phone network and other network testing environment, the send and receive real-time testing which the export data were 100M/1000 M, and time pointswere 17:00 and 21:00 two periods was completed.The results show that the WebSocket intelligent home gateway has good real-time performance.At the same time, the intelligent home gateway visual intelligent operation control platform was also designed, realizing remote real-time control of a plurality of terminal equipment in the same interface and the unified control functions in different interface. more intuitive in different test conditions of intelligent home gateway real-time control one-way wireless color bulb the lamp and sensor data response data, and thus a comparison of the corresponding performance results.Realization of intelligent home gateway based on WebSocket with real-time interactive manipulation characteristics directly support the Web connection.
