The invention discloses a rail vehicle speed measurement method, device and equipment and a readable storage medium, belongs to the field of rail vehicles, and is used for measuring the speed of the rail vehicle. Considering that when the railway vehicle runs at a low speed, the accuracy of the speed measured through the counting sleeper method is low, the real-time speed measured based on the counting sleeper method can be directly used as the current speed of the railway vehicle when the real-time speed of the railway vehicle is not smaller than the preset threshold value, and when the real-time speed of the railway vehicle is smaller than the preset threshold value, the real-time speed of the railway vehicle can be directly used as the current speed of the railway vehicle. The real-time speed is compensated through the real-time acceleration value of the vehicle, and in consideration of the fact that the acceleration value measured by the accelerometer is affected by the slope angle of the position where the vehicle is located, the real-time acceleration value, collected by the accelerometer, of the railway vehicle can be corrected through the real-time slope angle of the position where the railway vehicle is located, and the real-time speed of the vehicle is corrected. The accurate real-time acceleration value is obtained, the speed measurement accuracy of the railway vehicle in the low-speed state is improved, and few computing resources are consumed.

    本发明公开了一种轨道车辆测速方法、装置、设备及可读存储介质,属于轨道车辆领域,用于对轨道车辆进行测速。考虑到轨道车辆在较低速度运行时,通过计数轨枕法测量的速度精度较低,本申请可以在轨道车辆实时速度不小于预设阈值时直接将基于计数轨枕法测量的实时速度作为轨道车辆的当前速度,而在轨道车辆实时速度小于预设阈值时,通过车辆实时加速度值对实时速度进行补偿,且考虑到加速度计测得的加速度值会受车辆所在位置的坡角的影响,本申请可以通过轨道车辆所在位置的实时坡角,对通过加速度计采集的轨道车辆的实时加速度值进行修正,得到精准的实时加速度值,提升了低速状态下轨道车辆的速度测量精度,且耗费计算资源较少。
