矿山无极绳绞车无线视频监控无缝漫游切换技术

The Seamless Roaming and Handoff Technology for the Endless Rope Winch Wireless Video Surveillance System in Mine

针对矿山无极绳绞车无线视频监控需求,对无线越区切换进行研究,提出了基于HaND算法的无缝漫游切换优化算法,并通过实验证明优化算法的可行性。该技术进一步减少了切换延迟,视频切换时间小于一帧,满足矿山无极绳绞车无线视频监控的实时要求。

For the demand of the endless rope winch wireless video surveillance in mine,this paper studies the wireless handoff. The optimized seamless roaming handoff algorithm is proposed based on HaND algorithm and the feasibility of the optimized algorithm is proved by experiments. The optimized technology further reduces the handoff latency and the video switching time is less than the time of one frame,so the optimized algorithm meets real-time requirements of endless rope winch wireless video surveillance in mine.
