| 摘要 | The disclosure is directed to a method of detecting an object beneath a train. The method may include receiving a first signal indicative of a speed of the train, receiving a second signal indicative of a three generated by impact of the object with an impact element, and selecting a threshold value based on the speed of the train. The method may also include processing the second signal in accordance with a first procedure if the first signal indicates a speed of the train less than the threshold level, and processing the second signal in accordance with a second procedure different from the first procedure if the first signal is equal to or greater than the threshold level. | ||

| 主权项 | 1. A method of detecting an object beneath a train, the method comprising: receiving a first signal indicative of a position of the train; receiving a second signal indicative of a force generated by impact of the object with an impact element; determining a speed of the train; selecting a threshold speed value based on the speed of the train; processing said second signal in accordance with a first procedure if the speed of the train is less than the threshold speed value; and processing said second signal in accordance with a second procedure different from said first procedure if the speed of the train is equal to or greater than the threshold speed value, wherein the first procedure and the second procedure are selected based on a sensitivity of the impact element. | ||
