We adopted the coder to control the length of the walking line, carrying out the higher index sign of the fixed position accuracy, at the same time because of need control to hang the object to complete the circumference sport in the in a short time, and the other by oneself sets of higher action of difficulty etc., adopted the power slightly a little bit tread into the electrical engineering greatly. The sport track that hangs the object is to pass to make use of the formula precision calculations, such as related mathematics and physics...etc. to come out of, so also relatively near to the design of request. Control the system and the manifestation parts adopts a system with minimum machine of 89C52　to control the realization. In order to decrease the error margin, we make use of the coder to decrease the result in of hang object physically walk the line appear of deviation because of fix outside tread into the electricity on board certainly pulley of path with round the let up of line or increase. For enlarging the electrical engineering actuator to drive the ability, we used the triode transistor to gather chip. For letting up the pulley to take off the line problem, use the old CD conduct and actions of fee to block the plank. This system was basic to complete various technique index sign of that design mission. Key　words：Suspension motion control system； Thin enter the electrical engineering actuator at every step； coder； tread into the electrical engineering 第一章 系统方案设计与论证 1.1 设计要求 1.1.1 基本要求 （1）正确使用PIC单片机（pic16f877）来实现实验。 （2）控制系统能够通过键盘输入控制
