Embodiment Construction
[0008] The technical solutions of the present invention will be described in further detail below through specific implementation methods.
[0009] A method for trains to detect railways. Radar detection signals are emitted from the bottom of the front of the train along the railway tracks. According to the principle of radar detection, if there is an obstacle, the obstacle will reflect the radar detection signal. The feedback signal can determine whether there is an obstacle; in addition, the position of the obstacle can be calculated according to the radar detection signal and its feedback signal transmitted twice. The train detects whether the feedback signal of the radar detection signal is received; if the feedback signal is not received, it is judged that there is no obstacle on the train track; if the feedback signal is received, the coordinate position of the obstacle is calculated according to the received feedback signal , and combined with the satellite map of the t...

The invention provides a method for detecting a railway by a train. The method comprises the steps that a radar detecting signal is emitted from the lower portion of the front part of the train alonga railway track; the train detects whether a feedback signal of the radar detecting signal is received or not; if the feedback signal of the radar detecting signal is not received, the situation thatno obstacle exists in the train railway track is judged; if the feedback signal of the radar detecting signal is received, the coordinating position of an obstacle is calculated according to the received feedback signal, and whether the feedback signal is a normal terrain feedback signal or not is judged by combining a satellite map of the train railway track; and if the feedback signal is the normal terrain feedback signal, the situation that the feedback signal at this time is safe is judged, or the situation that the obstacle exists in the train railway track is judged, and the train conducts braking deceleration. The method for detecting the railway by the train has the advantages of scientific design, high practicability, accurate measurement, convenient and fast effects, safety and high efficiency.
Description
technical field [0001] The invention relates to a method for a train to detect a railway. Background technique [0002] Existing railway track systems extend in all directions, and due to the long distances, proper safety detection is not possible. Due to the high speed of the train and the long parking distance, if there is any obstacle on the train track, the train cannot immediately stop the train in a short distance like a car. According to my country's train operation regulations, the maximum train parking distance is up to At 800 meters, when an obstacle is found to stop, it usually takes tens of seconds to stop the train, so accidents such as train hitting people or cars often occur. [0003] In order to solve the above existing problems, people have been seeking an ideal technical solution. Contents of the invention [0004] The object of the present invention is to aim at the deficiencies of the prior art, thereby providing a method for detecting railways by trai...
