This paper precisely conducts the special topic research in view of some important technologies of the digitized control module.(1) AC motor control circuit of PAN/TILT is designed ,which speed is controlled by AT89C51 MCU. DC motor control circuit of LENS is designed too.(2) The hardware and software of automatic temperature control is designed, which used in camera protect box without A/D IC. A kind of single wire communication IC is used in the circuit. So, the program is given.(3) A method of video switch without picture shock is discussed in this paper, and 16x8 video switch circuit is designed. AT89C51 can carry out time sequence logical control with the sync signals by request..(4) The module of real-time clock is designed, in which, LCM is used, a kind of three-wire communication IC is used too.

1给出了一种由89C51单片机控制的简单易行的交流云台转动变速控制电路，实现了云台及其电动三可变镜头的控制；(2)给出了无需外加A/D、单线通信的防护罩自动温度控制电路，完成了单片机温度控制软件的设计；(3)提出了"无抖动"视频切换的设计思想，给出了16×8的视频切换电路，利用单片机在视频信号的场消隐期控制切换，从而实现了"无抖动"切换；(4)给出了一种三线接口通信的液晶显示实时时钟电路，完成了程序设计；(5)提出了在视频监控系统数字控制模块中，用CAN总线取代传统的RS-485总线，实现PELCO-P协议传输的方案。
