摘　　要：不同接入协议导致物联设备间不能实现信息的精准交换,为解决该问题,设计基于数据融合的海量物联设备接入协议自适应转换系统,实现海量物联设备接入协议的精准转换,节省转换时间。该系统内数据融合层是利用改进的证据理论加权融合算法,融合海量物联设备接入协议的相关数据包,上传至设备接入层;设备接入层负责接收并存储融合后的接入协议数据包,利用统一的数据帧格式完成接入协议数据包自适应转换,将封装与解析转换后的数据包推送至通信层;通信层完成设备接入层与主控制器间的全双工通信。实验证明,该系统海量物联设备接入协议自适应转换的准确性较高,且转换时间较短。Different access protocols make it impossible to achieve accurate information exchange between IoT devices.In order to solve this problem,an adaptive conversion system of access protocols for massive IoT devices based on data fusion is designed to achieve accurate conversion of access protocols for massive IoT devices and save conversion time.The data fusion layer in the system uses the improved evidence theory weighted fusion algorithm to fuse massive data packets related to the Internet of Things device access protocol and upload them to the device access layer.The access layer of the device is responsible for receiving and storing the fused access protocol packets,completing the adaptive conversion of access protocol packets by using the unified data frame format,push the encapsulated and parsed converted data packet to the communication layer.The communication layer completes the full-duplex communication between the device access layer and the main controller.The experiment proves that the system has high accuracy and short conversion time for adaptive conversion of massive IoT equipment access protocols.
