The invention discloses a method for determining a b value of a contact network compensation device. The compensation device comprises a limiting tube and a pendant string, the pendant string is provided with a scale, and the limiting tube is provided with a reference point. The method comprises the steps of: acquiring an image comprising the compensation device collected by an image collection device; determining the positions of the reference point and the scale in the image; determining a scale value corresponding to the reference point on the scale; and determining the b value according tothe scale value and a preset height of the reference point. According to the method disclosed by the invention, by collecting the image of the compensation device and performing recognition analysisin the image to determine the b value, the efficiency is not only higher than that of manual judgment, compared with several sensor distance measurement methods in the prior art, the adaptability to different weather environments is higher, furthermore, the cost is lower, the process of mounting corresponding equipment is simple, there is no potential safety hazard, and the method can be popularized in a large area for use.
Description
technical field [0001] The present application relates to the field of image processing, in particular to a method and device for determining the b value of a catenary compensation device. Background technique [0002] Catenary compensation device is a general term for the compensator and its braking device that automatically adjusts the tension of the contact line and catenary cable. The compensator keeps the tension of the wire in balance by the gravity of the weight string. When the temperature changes, the expansion and contraction of the thread makes the weight string rise or fall, thereby changing the a value and b value of the compensation device. Among them, the distance from the center of the earring hole of the pendant rod to the lower edge of the compensation pulley is the a value; the distance from the bottom surface of the pendant to the ground or the base surface is called the b value of the compensator. When the weight string goes up and down beyond the allow...
