摘要
在天线外场自动测量系统中,通过AT89C51控制75BF003型步进电机转动,带动步进电机上的转台平稳转动,测得放置在转台上的待测天线的幅度方向图。文中给出详细的软硬件设计方法。实验证明,该转台控制系统工作稳定可靠,完全满足天线自动测量的要求。
In the far-field antenna automatic measurement system, the 75BF003 stepping motor is controlled by AT89C51, then the rotating platform on the motor is wheeling stably, thus the amplitude patterns of the tested antenna are gotten. In the article, detailed methods of designing software and hardware are also provided. The experimental results show that the system works stably and reliably, satisfying the requirement of the antenna automatic measurement.
