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.

In addition, depending on the method of numerical simulation and theoretical analyses, some kinematic and geometric features of 0° involute—enveloping worm gear drive, such as meshing surface, first—type limit, second —type limit, worm surface, the numerical representation of contact line and bearing contact, are systematically studied. These relevant conclusions provide an important basis for the design and manufacture of new type worm gear set. As we predict, the method of numerical simulation has special effect in solving the question of complex conjugate surface.
