摘　　要：该文主要论述了以太网技术在智能家居系统中的应用与实现,完成了智能家居网关的设计。智能家居网关以32位高性能单片机STM32为核心控制器,通过以太网控制器支持TCP、UDP和DHCP PPPOE协议。智能家居网关通过以太网接收各智能节点所采集的环境数据(温度、湿度、CO浓度等)并对数据进行处理,同时用液晶屏显示各个节点的信息。另外智能网关可按需设置不同的报警阈值,当设定的报警阈值小于节点的实际测量值时,可对危险信息进行报警同时通过以太网向节点发送相应的控制命令。测试结果表明该网关能够有效实现对各个智能节点信息的有效管理和处理。The application of Ethemet technology in intelligent home gateway system enables the intelligent home gateway design. The STM32 with 32-bit high-performance is used as action servlet with TCP, UDP and DHCP PPPOE protocol supported by Ethernet controller. Intelligent home gateway receives and processes the data （temperature, humidity, CO concentration, etc. ） collected by intelligent nodes through Ethernet and displays the informa- tion of nodes on liquid crystal screen （LCD）. Intelligent home gateway can set different alarm thresholds, when the set alarm threshold is less than the ac- tual measured value of the node, the intelligent home gateway can alarm and send control commands to the node via Ethemet. The test results show that the gateway can effectively manage and process the information of intelligent nodes.
