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。

C51 written by the calendar clock, this procedure can be used directly down.

详细说明：用C51写的日历时钟，这个程序可以直接下来使用。

The main goal of CISC designs was to reduce the number of instructions for executing programs.

CISC设计的主要目的是减少用于执行程序的指令数量，而RISC主要是减少每条指令时钟周期的平均数。

Digital clock shows the dynamic process, Dynamic Display System of time.

Digital Clock is an application which shows the time in full screen mode.

数字时钟是一种应用程序，显示的时间在全萤幕模式。

The Russian square piece is aget-away drama with all proper old young,it carry out to be constitute by four pieces of colors of exact square piece,then save in one four chemical elements of the piece set,random creation dissimilarity of calculator seven the square piece of the category type,control it according to the cal culator clock in certain time continuously creation,the customer is inside out according to four directions key control of the keyboard,to left,r·VB论文ightwards and get down the operation,.

俄罗斯方块是个老幼皆宜的小游戏，它实现由四块正方形的色块组成，然后电子商务论文存储在一个数组的四个元素中，计算机随机产生不同七种类型的方块，根据计算机时钟控制它在一定的时间不停的产生，用户根据键盘的四个方向键控制翻转、向左、向右和向下操作，(控制键的实现是由键盘的方向键的事件处理实现)。然后程序根据这七种方块堆叠成各种不同的模型。论文描述了游戏的历史，开发此游戏的环境，游戏开发的意义。

The hardware principles of the LCD clock system and main program flow charts were explained.
