Abstract

The invention discloses a vacuum pipeline speed measuring and positioning system and method. The system comprises a plurality of single-spectrum light sources with different wavebands, a vehicle-mounted image acquisition device that acquires spectral images of the plurality of single-spectrum light sources with different wavebands, and a control device that processes the image to obtain a tensor matrix of the image and locates the train according to the tensor matrix and light source data pre-stored in a light source database; the control device also judges whether the light source changes or not, if not, data in the light source database are updated with a tensor matrix, if so, the tensor matrix is converted into a column vector, the light source change distance is determined, whether light source tracking recognition succeeds or not is judged, and if so, the train speed is determined according to the light source change distance; and otherwise, whether the light source change distance is zero is determined, if so, data in the light source database are updated by using the column vector, otherwise, the data in the light source database are updated by using the column vector and the light source database is triggered to send the column vector, and the updated light source change distance is determined according to the sent column vector so as to determine the train speed.

Description

technical field

[0001] The invention relates to the technical field of speed measurement and positioning, in particular to a vacuum pipeline speed measurement and positioning system and method. Background technique

[0002] The vacuum tube train uses magnetic levitation technology to separate from the ground to eliminate friction, and uses vacuum tubes to greatly reduce air resistance to achieve near-ground flight.

[0003] Because the speed can reach more than 1000km, the cost of the traditional speed measurement method is extremely high. Traditional speed measurement and positioning include ground laser speed measurement and positioning, vehicle-mounted laser reflection sensor speed measurement and positioning, and cross-induction loop positioning and speed measurement.

[0004] For ground laser speed measurement and positioning, a laser sensor needs to be placed at a certain distance, and the speed measurement and positioning can be realized by blocking the laser sensor ...
