| The demand of smart household devices is growing and these devices are so different. But the low speed development of smart home standard leads to the compatibility problem of devices made by different manufacturers which seriously hinders the development of smart home product. In order to make all kinds of intelligent device connectivity, the problem of protocol conformance has to be solved.Aiming at the limitation of weak commonality problem of protocol conversion in smart home gateway, the paper analyzes intelligent household mainstream communication protocols. And the purpose is to solve the problem of consistency control of the smart home and to deal with the inconvenience of various protocols by using conformance gateway. It supports protocols for the lower computer such as zigbee, bluetooth, infrared, and allows the upper computer to access network like WIFI. It basically meets the existing intelligent household gateway protocol conversion requirement. Considering the characteristics of the time and space distribution of protocol conversion, the end node of smart home has been improved which significantly improves the conversion efficiency and reliability of the specific protocol. In view of the diversity of the infrared protocol, the gateway supports the corresponding infrared learning function, and mostly realizes the communication and transparency of the household equipment in home gateway layer. Besides, a data processing machine is proposed in this paper. Through the effective management of data packets, the system performance is more stable, the efficiency of gateway protocol conversion is improved and the overall energy consumption of the gateway is reduced to some extent.At the same time, in order to make the system simple and easy to use, to achieve the goal of handheld management of intelligent device, we design the terminal management software. Through smart phone, the real-time data can be obtained and we can monitor the house better. |
