摘　　要：设计基于开放网络视频接口论坛(open network video interface forum,ONVIF)的物联网图像采集虚拟设备接口,虚拟设备接口由ONVIF客户端、虚拟设备层和网关通信层3部分组成,ONVIF客户端以ONVIF标准接入网络摄像机,虚拟设备层完成ONVIF标准与物联网平台协议的转换,网关通信层通过传输控制协议/因特网互联协议(transmission control protocol/internet protocol,TCP/IP)与网关通信。测试结果表明,支持ONVIF标准的网络摄像机接入以太网,即可通过虚拟设备接口连接到物联网平台,并向物联网平台传输图像。虚拟设备接口实现了网络摄像机通过以太网接口的即插即用接入和图像采集。The Internet of Things image acquisition virtual device interface based on ONVIF is designed in this paper. The interface consists of ONVIF client, virtual device layer and gateway communication layer. Network cameras are accessed by ONVIF client via ONVIF standard, ONVIF standard and the Internet of Things platform protocol conversion is completed by virtual device layer, and the gateway communication layer is communicated with gateway via TCP/IP protocol. Test results show that when network cameras that support ONVIF standard are accessed to Ethernet,it then can be accessed to the Internet of Things platform through the virtual device interface, and therefore images can be transferred to the platform. The function of network cameras＂ plug and play access through Ethernet interface and image acquisition is thus successfully realized by the virtual device interface.
