The relationship among the rotation direction of vehicle antenna,the output driving pulse and transmission reduction ratio of PLC was studied,and reasonable reduction ratio was proposed,so that the rotation direction of the vehicle antenna and the pulse series accorded with actual needs.
应用可编程序控制器(PLC)与电机变频技术,提出了快速调整车载天线方向的构想与设计方法,研究了车载天线转动方向与PLC输出的驱动脉冲、传动减速比之间的关系,并提出了合理的减速比,使车载天线转动方向与脉冲串符合实际需求。
