嵌入式智能网关与感知层设备通信时，需要根据感知层设备不同协议分别开发驱动，灵活性较差。针对此类问题，一种协议可配置的方法被提出，它用于实现智能网关与感知层设备的通信。首先，通过对设备协议进行分析，根据原始协议帧的对象设计该设备的协议模板；然后，驱动引擎解析协议模板并组建设备可识别的通讯的协议帧，智能网关根据新组建的协议帧与感知层设备通讯，并获取数据；最后，目标协议转换程序加载目标协议模板并将采集来的数据封装成目标协议，达到协议可配置和转换的目的。实验结果表明，该方法通过数据建模较好地实现了数据通信和协议转换。

When embedded intelligent gateway communicates with devices of the perceptual layer,it needs to develop different protocols based on the devices and the method is not flexible. For these problems,a method of configuration for protocol conversion is proposed. It is used to communicate between intelligent gateways with perceptual layer devices. First,the protocol template for device needs to be de-signed according to the objects of the original protocol frame through analyzing the device protocol. Then,the drive engine analyzes the protocol template and establishes protocol frame that can be identified by devices. Intelligent gateway communicates with devices of the perceptual layer through the protocol frame be established and obtains the data. Finally,the target protocol conversion program loads the target protocol template and encapsulates the data collected into the target protocol to achieve protocol configuration and protocol conver-sion. The experimental results show that the method preferably realizes data communication and protocol conversion through data model-ing.
