Rail flaw detection car management map system

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 positionin
