Embodiment Construction

[0071] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0072] see figure 1 , the embodiment of the present application provides a train speed control device 100, the train speed control device 100 can be set on the train, so as to determine the speed of other trains by collecting the pressure wave data generated by other trains running, and through other trains The speed of the train and the speed of the train you are in, before the train you are in and other trains meet, judge whether you need to control the speed of the train you are in.

[0073] As an exemplary way of setting the train speed control device 100, a train speed control device 100 can be set on each train, so that each train can control its own vehicle speed when passing through the train speed control device 100, so as to Avoid excessive body pressure when meeting cars.

Abstract

Embodiments of the present application provide a train speed control method, device, and storage medium. The method includes: acquiring pressure wave data collected by a pressure wave collector, wherein the pressure wave collector is arranged on the outer surface of the first train; according to the pressure wave data, determining the current speed of the second train that will intersect with the first train ;According to the current speed of the second train and the current speed of the first train, estimate the body pressure between the first train and the second train when the first train and the second train meet; if the body pressure is greater than the preset safety Pressure, control the deceleration of the first train before the intersection of the first train and the second train. The pressure wave generated by driving in the tunnel can accurately judge whether the oncoming vehicle is coming, and the speed of the oncoming vehicle can be accurately determined through the pressure wave, so it can be accurately judged whether the passing vehicle needs to slow down to avoid mistakes Judging the situation that leads to untimely deceleration.

Description

technical field [0001] The present application relates to the technical field of vehicle control, in particular, to a train speed control method, device and storage medium. Background technique [0002] Two trains traveling in opposite directions will generate crossing pressure waves when they meet. However, too large a vehicle meeting pressure wave acting on the vehicle body can cause broken windows and even vehicle overturning. Therefore, it is necessary to reduce the pressure wave of the train meeting by reducing the speed of the train meeting. However, due to the special environment of the tunnel, communication signals are difficult to propagate in the tunnel. Generally, the driver's naked eye observation is used to determine the speed and position of the oncoming vehicle, so as to determine whether to slow down. However, in long tunnels, the naked eye cannot accurately determine the speed and position of oncoming vehicles, and even due to the slope of the tunnel, it i...
