平面直角定位系统的电路设计

CIRCUIT DESIGN FOR PLANE RECTANGULAR COORDINATES AUTOMATIC POSITION SYSTEM

设计出以步进电动机拖动为核心的平面直角自动定位系统电路，其中包括单片机输出接口线路、光电耦合线路、驱动线路、直流电压源电路等。由缓冲寄存器、环形分配器、控制逻辑及正反转控制门组成的步进电机控制器则用计算机软件替代。实验结果表明，系统的硬件线路简单，抗干扰能力强。

This paper advances the circuits of step motor plane rectangular coordinates automatic position system controlled by single chip computer.It includes the single chip computer output circuit,the opto coupler,the driving circuit,the direct current source etc.The step motor controller composed of buffer register,the circular allotter,the control logic,the positive run and back run control circuits is replaced by computer software.The test result proves that the system hardware circuits are simple and the system has more anti interference ability.The system is correct.
