摘要
提出了一种模拟监控系统网络化改造方案,利用网络控制器NC(Network Controller)代替模拟监控系统中的交换矩阵。NC的主要功能是实现MPU(Main CPU)和编解码器之间的协议转换。详细描述了NC摄像机控制单元的设计方法及实现,利用透明通道实现对摄像机的控制。测试表控制单元能够实时的完成对摄像机的各种控制功能。
A network reconstructive project of the analogue surveillance system is presented, in which switch matrix of the analogue surveillance system is replaced by the NC （ Network Controller）, The main function of the NC is to convert the protocol between MPU （main CPU） and encoder, The design and implementation of camera control unit is described in detail, The transparent channel is chosen to achieve camera control, Test results show that the control unit can fulfill all the camera control functions real -timely.
