Non-contact measuring method and equipment for railway catenary parameters

Abstract

The present invention provides a non-contact measurement method of railway catenary parameters and a device. The method comprises the steps of using a unmanned flight device to acquire the connection lengths between a measurement point and two steel rails and between the measurement point and a contact line, the included angle of the connection lines between the measurement point and the two steel rails, and the included angles of the connection lines between the measurement point and one steel rail and between the measurement point and the contact line; according to the measured distances and the included angle values, obtaining the railway catenary parameters. According to the embodiment of the present invention, and during the process of using the unmanned flight device to measure the railway catenary parameters, a measurement process can be finished by the device autonomously, and also can controlled by the manual operation to finish, so that the whole measurement process is more convenient and flexible. Moreover, the measured data can be reported to an appointed device or user actively, thereby being convenient to apply the corresponding catenary parameters.

Description

technical field [0001] This patent relates to the field of measurement technology, in particular to a non-contact measurement method and equipment for railway catenary parameters. Background technique [0002] The contact wire in the catenary is the power supply line of the electrified locomotive, and it is matched with the pantograph on the train (the contact surface is a slide plate). Through the contact between the contact wire and the pantograph, the train can obtain 25kV high-voltage alternating current. [0003] In order to ensure reliable contact between the contact wire and the pantograph and good power supply, it is necessary to reasonably design the height of the contact wire and the pull-out value parameters during the circuit design process. Among them, if the design value of the contact wire height is unreasonable or the construction does not meet the design value, it will lead to discontinuous contact between the contact wire and the pantograph, resulting in hi...

Problems solved by technology

[0004] At present, in the usual way of catenary parameters such as catenary height and pull-out value, there are high-precision measurement by motor vehicles or special catenary inspection vehicles, but the cost is high; there are portable measuring instruments, but the efficiency is low
