The embodiment of the invention provides a train speed measurement method and device and a train, and the method comprises the steps: measuring a first speed of the train in a current period through a first speed sensor; measuring a second speed of the train in the current period through a second speed sensor; determining a third speed of the train in the current period according to the acceleration value in the current period; and under the condition that the difference value of the first speed and the second speed does not meet the preset condition, the third speed is compared with the first speed and the second speed, so that the train speed of the current period is obtained. According to the train speed measurement method and device, normal train speed measurement can still be achieved when any speed sensor breaks down by means of the acceleration value of the current period, and therefore the reliability and accuracy of train speed measurement are greatly improved.
本申请实施例提供一种用于列车测速的方法、装置和列车,其中,所述方法包括:通过第一速度传感器测量列车在当前周期的第一速度;通过第二速度传感器测量列车在当前周期的第二速度;根据当前周期的加速度值,确定列车在当前周期的第三速度;在所述第一速度与第二速度的差值未满足预设条件的情况下,将所述第三速度分别与第一速度和第二速度进行比较,以获取当前周期的列车车速。本申请利用当前周期的加速度值,在任意一个速度传感器发生故障时,仍然能够实现正常的列车测速,从而极大地提高了列车测速的可靠性和准确性。
