| 摘 要： | 针对铁路线路维修后使用的静态限速标志牌带来的人力、物力资源的浪费，由于疏忽产生的不安全隐患等问题，采用AT89C51单片机进行控制，应用光电传感器和磁电感应式传感器设计了动态限速标志。动态限速标志具有定时和定次两种工作方式，单片机通过程序控制电机转动，转换限速值。动态限速标志可方便设置工作方式，性能稳定可靠，能充分保证铁路机车的安全运行。

| Abstract: | The paper analyzes the human and material resources wastes resulting from static speed-restricting sign left behind by railway line maintenance or hidden insecurity trouble due to neglect. The paper introduces the design of dynamic speed-restricting sign using AT89C51 and photo electricity sensor and magnetoelectricity sensor. Dynamic speed-restricting sign has two working of timing and time. Microcontroller controls motors turning to change the value of restricted speed using the program. It presents easier operation, more stable performance and credibility and allows train safe operation of trains. |
