The invention provides a grid-based train speed measuring and positioning system. The grid-based train speed measuring and positioning system comprises a train body, a track, a first grid, a second grid, a recognition device and a controller, the vehicle body is arranged above the two rails; the first grid is transversely arranged between the two rails and located between the vehicle body and the rails. The second grid is vertically arranged on the two rails; the first grid interval is larger than the second grid interval; the recognition device is used for recognizing the first grid when the train is in the first state and recognizing the second grid when the train is in the second state so as to obtain corresponding pulse signals; and the controller is used for acquiring the average speed and the real-time position of the train according to the pulse signal. The system can solve the technical problem that speed measurement and positioning are not accurate due to the fact that the running state of the train is not distinguished in the prior art, and the speed measurement and positioning accuracy and efficiency of the running train are improved.

    本发明提供了一种基于栅格的列车测速定位系统,包括:车体、轨道、第一栅格、第二栅格、识别装置和控制器;车体设置在两条轨道上方;第一栅格横向设置在两条轨道之间,且位于车体和轨道之间;第二栅格竖向设置在两条轨道上;第一栅格间隔大于第二栅格间隔;识别装置用于在列车处于第一状态时,识别第一栅格和在列车处于第二状态时,识别第二栅格以分别获取对应的脉冲信号;控制器,用于根据脉冲信号获取列车平均速度与实时位置。该系统可以解决现有技术并未区分列车行驶状态所进行测速定位导致不精准的技术问题,提高对行驶中列车的测速定位精准度及效率。
