Embodiment 1

[0087] as attached figure 2As shown, an embodiment of the rail flaw detection vehicle management map system 1 based on the present invention is used for issuing flaw detection plan tasks, the vehicle map forms a track map, the rail flaw detection detection system 4 records and detects B-type maps, and the rail flaw detection playback analysis computer 40 for damage location analysis, which can well realize the refined maintenance of railway lines. The rail flaw detection vehicle management map system 1 specifically includes: a ground map computer 2 and a vehicle-mounted map computer 3, both of which are computer-based devices. The ground map computer 2 is used for storing, managing, applying and displaying the ground map, and the vehicle-mounted map computer 3 is used for storing, managing, applying and displaying the vehicle-mounted map. The specific working process of the rail flaw detection vehicle management map system 1 includes: entering the railway line database data ...

Embodiment 2

[0123] as attached figure 1 As shown, an embodiment of the method for forming a rail flaw detection vehicle management map of the present invention can automatically form a railway line vector map, call railway line data, display a specific path, and combine high-resolution mileage pulses to realize precise and automatic detection results of rail flaw detection vehicles Positioning, to solve the technical problems that the existing flaw detection vehicle needs to rely on manual input of reference object positioning every time it runs, resulting in high labor intensity, large positioning errors, and frequent on-site review omissions. The method specifically includes the following steps:

[0124] S100) The ground map computer 2 establishes a railway line database: the source of the railway line database is the updated data after the work flow in Embodiment 1 is completed, as shown in Table 3.

[0125] S101) The ground map computer 2 sends the railway line database data to the o...

Embodiment 3

[0172] A specific embodiment based on the rail flaw detection car management map formation method described in Embodiment 2 applied to offline map management, the railway line database has been fully formed, the on-board map computer 3 runs independently offline, and the ground map computer 2 does not need to be updated. The rail flaw detection system 4 records the running path and detects the B-type map file, and analyzes and locates the rail damage. The specific work flow of the rail flaw detection vehicle management map system 1 includes: the on-board map computer 3 displays the line map according to the complete railway line database shown in Table 6, as attached Figure 11 shown. The on-board map computer 3 edits the planned route table as shown in Table 7 below, and displays the planned route map. The rail flaw detection vehicle is running, and the on-board map computer 3 receives the positioning data and performs track correction and display. The on-board map computer...

Abstract

The invention discloses a rail flaw detection car management map forming method. The method comprises the following steps: a ground map computer is used for editing and establishing a railway line database, managing the running path of a rail flaw detection car, collecting track lines formed by a rail flaw detection car vehicle-mounted map computer and generating a railway line vector map; the rail flaw detection playback analysis computer calls the ground map computer through communication to automatically position the flaw of the rail flaw detection B-type diagram; a vehicle-mounted map computer obtains satellite positioning data and mileage pulse data through a positioning measurement system, a track line is formed by the satellite positioning data, and positioning association is performed by the mileage pulse data and a steel rail flaw detection B-type graph. The invention can solve the technical problems of high manual labor intensity, large positioning error and frequent onsite recheck report omission caused by the fact that the existing flaw detection vehicle depends on manual input reference object positioning during operation each time.

Description

technical field [0001] The invention relates to the technical field of track engineering, in particular to a method for forming a management map applied to a rail flaw detection vehicle. Background technique [0002] The existing rail flaw detection vehicle forms a B-type map through ultrasonic flaw detection. During the inspection process, a manual keyboard is used to input reference objects such as track side kilometers, poles, and tunnels, and ground benchmarks. The map is analyzed, and after the damage is diagnosed, the on-site personnel are notified to review and confirm whether it is repaired. The B-type map relies on the reference object plus the pulse distance for positioning. Due to the high running speed of the rail flaw detection vehicle, the positioning of reference objects manually input is inaccurate, the scope of the review line is large, the labor intensity of the inspectors and review personnel is high, and the flaw detection management is difficult. [000...
