为简化传统智能家居系统的复杂结构，并增强其扩展性和易用性，提出了一种智能设备即插即用的智能家居系统。该系统引入智能插座，降低家庭网关与智能设备的依赖性，制定一种自定义即插即用协议，在设备注册阶段将设备的动作和状态提交给网关，并设计与该协议相适应的家庭网关。测试结果表明，该系统允许在不改动家庭网关的情况下连接不同类型的智能设备，虽然增加设备连接数会增加网关的内存消耗，但不影响网关的响应速度和数据包的丢失率，验证了该方法的有效性和可行性。%A plug and play method for intelligent devices in smart home systems is presented , to simplify the structure of the smart home system, enhance its scalability and make it easy for use. The system introduced the smart socket, which reduced the dependency between the smart home gateway and the intelligent devices. A custom plug and play protocol was proposed , in which the actions and status of the intelligent devices were submitted to the gateway in the stage of device registration. In addition , a home gateway was designed according to the proposed protocol. The test results show that the home gateway without changes can be connected by different types of intelligent device, and increasing the number of devices connected to the gateway will increase the amount of memory consumption, but it will not affect the response speed of the gateway and the loss rate of data packets. Therefore, the validity and feasibility of the presented method is demonstrated.
