基于GPS的列车前照灯转向控制系统的研究

Research on the Steering Control System of Locomotive Front Illuminator Based on GPS

针对由于列车提速带来的铁路弯道处的前照灯自动转向问题,提出了一种基于GPS的转向控制系统。通过分析前照灯转速、转角与列车位置,建立转角控制系统数学模型,并构建以LPC2136为主控芯片,GPS15L为GPS信息接收器件,步进电机为驱动的系统硬件平台,并设计了控制系统的软件。实验结果表明,基于GPS的转向控制系统能够实现列车前照灯照射方向控制。

The speed boost of the trains makes the illumination at the railway curves a serious problem. One system based on GPS for controlling the veering of front illuminator was proposed. The mathematical model of the steering control system was set up through analyzing the rotate speed and angle of front illuminator and the relative position of train. The hardware for controlling the steering control system was built with LPC2136 as main control chip, GPS15 L as the GPS information receiver, stepper motor as the driver, and the software was designed. It＇s proved by experiments that this system can achieve the veering control of the front illuminator.
