背景技术Background technique
近几年，随着计算机及网络多媒体技术的发展，流媒体系统在煤矿监控领域获得了广泛的应用。目前，矿用摄像机多为模拟摄像机，基于模拟摄像机的监控系统必须专门设置一个监控中心；而且，监控中心占地面积比较大，并且需要铺设专用的视频线、音频线、控制线。实际应用中，由于矿井下存在的高噪声、高丢包率等复杂网络环境的问题；故在监控中心铺设这些视频线、音频线、控制线时，出现了费时、费力、费钱的问题。另外，由于当前矿用监控系统使用的硬盘录像机最多只能管理32路图像，且像素较低，故监控中心的监控画面也不清晰。In recent years, with the development of computer and network multimedia technology, the streaming media system has been widely used in the field of coal mine monitoring. At present, most mining cameras are analog cameras, and a monitoring system based on analog cameras must have a dedicated monitoring center; moreover, the monitoring center occupies a relatively large area and requires laying dedicated video cables, audio cables, and control cables. In practical applications, due to the complex network environment problems such as high noise and high packet loss rate in mines; therefore, when laying these video lines, audio lines, and control lines in the monitoring center, there are problems of time-consuming, laborious, and expensive. In addition, because the hard disk video recorder used in the current mining monitoring system can only manage 32 channels of images at most, and the pixels are low, so the monitoring picture in the monitoring center is not clear.
由此可见，现有技术中，监控系统具有成本高、图像不清晰等问题。It can be seen that, in the prior art, the monitoring system has problems such as high cost and unclear images.
