Tv Seeker Biaxial Simulation Platform Design

A sort of two-axes simulation experimentation platform has been designed in the dissertation. The system is a DC motor control system with a control core of 89C51 MCU (micro chip computer). Not only it can be used for dragging TV-seeker as a two-axes swinging platform, but also for simulating the pitching and yawing movement of the bomb body in the sky. If the object dragged is the CCD photics photography system, the whole system can be used as a frame-style TV-seeker demo-system.The system's operation principle, functions and realization of each component were discussed in detail. The system's principle circuit has been designed using Protel99SE. The motor driver chip L293D was expanded, then the system realized clockwise and anti-clockwise running at azimuth and pitching for a certain given angle range.The modularization programmer technique was adopted in the design of control software, and the inside timers and interrupt functions were also used. The Keil C51 language has been used for designing the main function, the 8279 initialization subprogram, the 8279 keyboard inquiry managing subprogram, the 8279 display subprogram, the keyboard classifying subprogram and the key-press service subprogram.Ultimately the design of hardware and the debug of software were accomplished, and the design aim was achieved through the testing of the prototype performance of the system.
