Embodiment 1

[0060] as attached figure 1 As shown, an embodiment of the rail flaw detection vehicle management map system 1 of 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 the B-type map, and the rail flaw detection playback analysis computer 40 performs flaw detection. Damage location analysis 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 dat...

Embodiment 2

[0096] as attached image 3 As shown, an embodiment of a method for forming a rail flaw detection vehicle management map based on the system described in Embodiment 1 can automatically form a railway line vector map, call railway line data, display a specific path, and combine high-resolution mileage pulses to realize rail The precise and automatic positioning of the detection results of the flaw detection vehicle solves the technical problems that the existing flaw detection vehicle needs to rely on manual input of reference objects for positioning every time it runs, resulting in high labor intensity, large positioning errors, and frequent on-site review and false reporting. The method specifically includes the following steps:

[0097] 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.

[0098] S101) The ground map computer 2 ...

Embodiment 3

[0147] A specific embodiment based on the rail flaw detection vehicle management map system 1 described in Embodiment 1 applied to offline map management, the railway line database has been fully formed, the on-board map computer 3 runs independently offline, the ground map computer 2 does not need to be updated, and the rail flaw detection The detection system 4 records the running path and detects the B-type map file, and analyzes and locates the damage of the rail. 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-b...

Abstract

The invention discloses a rail flaw detection vehicle management map system which comprises a ground map computer and a vehicle-mounted map computer. And the ground map computer is used for editing and establishing a railway line database, managing the running path of the rail flaw detection car, collecting a track line formed by the vehicle-mounted map computer of the rail flaw detection car, and generating a railway line vector map. A steel rail flaw detection playback analysis computer calls the ground map computer through communication to automatically position the flaw of a steel rail flaw detection B-type graph. The 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 the steel rail flaw detection B-type graph. The system 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 rail engineering, in particular to a management map system applied to rail flaw detection vehicles. Background technique [0002] The existing rail flaw detection vehicle forms a B-type map through ultrasonic flaw detection. During the detection operation, a manual keyboard is used to input reference objects such as track side kilometers, poles, and tunnels, and ground benchmarks. After the detection is completed, analyze the detection B-type map on the ground, and then notify the on-site personnel to review after diagnosing the damage to confirm whether it is repaired. The detection B-type map depends on the reference object plus the mileage 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 h...
