摘要
本系统不仅具有同时在10个监视点观察16个摄像点的视频信号的功能,还能对这16台摄像机进行遥控。由于采用了单片微机智能元件,许多功能可以通过软件实现,系统的硬件结构简单、实用且可靠性高。利用软件测速的方法,在传输码速偏离设计值(300band/s)50倍的情况下,仍可正确接收遥控信息,优先级排队的软件化,方便地解决了多点遥控信息之间的相互冲突问题。
This system can not only observe simultaneously the video-signals from 16 TV cameras at 10 different monitoring points, but also telecontrol the 16 TV cameras. The hardware structure in the system is simple, applicable and reliable, because the intelligent components have been adopted and a lot of functions can be achieved by software. Even if the symbol rates deviate from the designed value (300 baud / s)in 50 times, the remote signals can still be exactly received by means of measuring the symbol transmission: rates of signals with software, The clash among remote signals from multiple spots is completely eliminated by determining priority with software.
