Problems solved by technology

[0003] However, the above-mentioned design still has shortcomings. The above-mentioned design is inconvenient to quickly detect the defect of the pantograph, and cannot notify the pantograph maintenance platform in time when the defect is detected, so that the replacement efficiency of the defective pantograph is relatively low. low, so we propose a pantograph bow defect detection method to solve the above problems

Embodiment

[0034] In this embodiment, a pantograph bow defect detection method is proposed, including the following steps:

[0035] S1: Enter information: enter the type information of the pantograph and the corresponding type standard parameter information in the database;

[0036] S2: Image acquisition: acquire the image information of the detected pantograph and compare and analyze it with the pantograph type information described in S1, and determine the type information of the detected pantograph;

[0037] S3: Identify the angle of the bow plane: identify the image information of the detected pantograph described in S2, obtain the angle value between the bow plane of the pantograph and the horizontal plane, and compare it with that of the pantograph described in S1 Standard parameter information for comparison;

[0038] S4: Preliminary judgment: judge whether the bow plane angle of the detected pantograph is normal according to the comparison result described in S3;

[0039] S5: d...

Abstract

The invention discloses a method for detecting bowing defects of a pantograph. The method comprises the following steps: S1) inputting information: inputting type information and standard parameter information of the corresponding type of the pantograph into a database; S2) acquiring an image: acquiring the image information of the detected pantograph, comparing with the type information of the pantograph in the step S1) and judging and acquiring the type information of the detected pantograph; S3) identifying an arc planar angle: identifying the image information of the detected pantograph inthe step S2), acquiring a value of an inclined angle between an arc plane of the pantograph and a horizontal plane and comparing with the standard parameter information of the pantograph. The methoddisclosed by the invention is reasonable in design and high in practicability; according to the method, the bowing defects of the pantograph can be quickly detected; a detecting flow can be timely stopped and a detecting result can be sent to a maintenance platform when the bowing defects are detected; the maintenance platform can timely maintain the pantograph, so that the maintaining efficiencyof the pantograph can be increased.

Description

technical field [0001] The invention relates to the technical field of pantograph bow defect detection, in particular to a pantograph bow defect detection method. Background technique [0002] With the rapid development of the national economy, the position of the railway transportation industry in the national economic and social development is becoming more and more important. At present, electric traction is the best way of railway transportation, which has many advantages such as improving transportation capacity, saving and comprehensively utilizing energy, reducing environmental pollution, and being easy to realize automation. In electric traction, the electric locomotive needs to reliably obtain electric energy from the catenary under high-speed operating conditions. The pantograph is the electrical equipment for the electric locomotive to obtain electric energy from the catenary. Normal work will directly affect whether the electric locomotive can run safely and sta...
