摘要
目前的井下电视在测井速度、耐温耐压、视频的传输速率等方面已经取得了较高水平,但在客户端视频的显示方面还存在一定差距,比如视频的分辨率、清晰度和实时动态的OSD显示等方面。为了解决不同厂商生产的网络摄像机、XVR/NVR设备之间的互通问题,使得整个监控系统之间的信息交互顺畅,基于ONVIF协议设计了一种井下电视客户端。实验结果表明,可以在设计的客户端上清晰地看到井下信息,实现实时动态的OSD显示,同时实现设备的发现、链接,视频的预览、存储、抓图等功能。
The current downhole TV has achieved a high level in logging velocity,temperature and pressure resistance,and video′s transmission rate,but there exists a certain gap in display aspects of the client video such as video resolution,defi?nition,and realtime dynamic OSD display.Therefore,a downhole TV client based on the ONVIF protocol is designed to re-solve the intercommunication problem between network cameras produced by different manufacturers and XVR/NVR devices,and make the information interaction in the whole monitoring system smooth.The experimental results show that the designed downhole client can display clear information,and realize real?time dynamic OSD display,discovery and link of devices,and functions of video preview,storage,and screenshot.
