Intelligent track flaw detection combined vehicle and a control method

Abstract

The invention belongs to the technical field of railway construction monitoring, and discloses an intelligent track flaw detection combined vehicle and a control method thereof. The intelligent trackflaw detection combined vehicle and the control method apply the internet of things technology and the modern control technology to realize self-walking, high precision, easy operation and remote control, assist to complete the railway fault detection of the large-scale flaw detection vehicle; Intelligent unmanned operation, self-walking, recording and real-time transmission of damage, mileage andline characteristics signals are realized; The flaw detection signals recorded by computer are processed to realize no take-off and landing or automatic take-off and landing. The invention is provided with two functional modules of manual detection and automatic detection, which can realize self-walking, high precision, easy operation and remote control by using the internet of things technologyand the modern control technology. At the same time, the industrial design elements are designed. It can not only help to complete the railway fault detection of large-scale flaw detection vehicle, but also completely replace the railway maintenance task of manual flaw detection equipment, which can better meet the requirements of track flaw detection.

Description

Technical field [0001] The invention belongs to the technical field of railway construction monitoring, and in particular relates to an intelligent track flaw detection combined car and a control method. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: [0003] At present, the non-destructive testing of rails at home and abroad is mainly based on ultrasonic flaw detection technology, which has the advantages of high sensitivity, fast speed, low cost, and harmless to the human body. It can locate and quantitatively detect defects. The existing equipment includes large-scale rail inspection vehicles, small-scale rail inspection vehicles, and hand-push-type small-scale rail inspection vehicles, all of which use ultrasonic waves for rail damage detection. [0004] With the rapid development of our country's economy, the important role of railways and rail transit has become more and more prominent. Once an accident occurs on ...

AI Technical Summary

Problems solved by technology

[0007] (1) The small hand-push flaw detection vehicle can only meet the basic detection functions, low detection efficiency, small scale, and cannot carry operators. The functional components carried are exposed, and the staff are prone to fatigue, which cannot meet the current railway flaw detection needs.

[0008] (2) The small track flaw detection vehicle can realize manned and unmanned driving, but the overall design of the current equipment is simple, lacks a sense of security, the overall size, structure and function are unreasonable, and the working seat does not conform to the man-machine, which is prone to fatigue , unable to meet the needs of equipped with precision instruments and a comfortable working environment for staff

[0009] (3) The large-scale flaw detection vehicle integrates multiple functions such as flaw detection, railway maintenance, and repair. It is large in size and has many restrictive factors in the detection environment. Generally, it is necessary to have a smooth and clean rail surface, and the detection method is off-line rail detection.

[0012] The invention solves the problem that the nationalized production has not yet been realized, the technology is monopolized by foreign countries, the expensive price limits the configuration quantity to a certain extent, and it is difficult to carry out effective work
