The invention discloses a high-speed train parking control method and system based on deep learning, and relates to the technical field of rail transit management and control. The method comprises thesteps of: obtaining a training data set; establishing a convolutional neural network; training and optimizing the convolutional neural network by using the training data set to obtain an optimized convolutional neural network; acquiring actual operation data of a to-be-controlled train; inputting the actual operation data into the optimized convolutional neural network to obtain a parking position of the to-be-controlled train; judging whether the parking position of the to-be-controlled train is 0 or not; if so, outputting a brake command; and if not, returning to the step of acquiring the actual operation data of the to-be-controlled train. Accurate parking of the high-speed train can be achieved without a large amount of cost.

The invention relates to the technical field of rail vehicle braking and discloses an axle-mounted brake device for a gauge-changeable wheel set. The axle-mounted brake device for the gauge-changeablewheel set comprises a transitional sleeve, a locating mechanism and a plurality of axle-mounted brake discs; the plurality of axle-mounted brake discs are fixed on the transitional sleeve at intervals; the transitional sleeve is connected with an axle of the gauge-changeable wheel set through a spline in a matched manner; and the locating mechanism is used for connecting the transitional sleeve with the axle so as to axially locate the transitional sleeve relative to the axle. According to the axle-mounted brake device for the gauge-changeable wheel set, by improving the connection modes between the axle-mounted brake discs and the axle, the relative positions of a brake clamp and the axle-mounted brake discs can be kept invariable during changing the gauge so that braking effects at different gauges are realized.

The invention discloses conveying vehicle stopping equipment used on a mine tunnel rail. The conveying vehicle stopping equipment used on the mine tunnel rail comprises a loading frame and a connecting box fixedly arranged at the lower end of the loading frame; and a transmission cavity with a downward opening is formed in the connecting box. According to the conveying vehicle stopping equipment used on the mine tunnel rail, by using a foot brake structure arranged on a wheel axle and a one-way shaft coupling structure connected with the foot brake structure, the synchronous rotation shaft coupling direction is arranged on an obliquely downward side; during the rolling of a wheel, the one-way shaft coupling structure starts the foot brake structure to limit the rotation of the wheel axle;and moreover, by using a mechanism with a centrifugal rotating disc, the foot brake structure part is pulled to guarantee that the foot brake part cannot interfere the movement of a vehicle no matterhow the advancing direction of the vehicle is changed in the case of normal moving; the equipment can be independently arranged on the wheel axle and automatically recognizes, judges and stops the vehicle without being manually started so that accidents are effectively prevented; and moreover, the conveying vehicle stopping equipment used on the mine tunnel rail can work together with an existingvehicle stopper to realize double vehicle stopping protection so that the safety of mine tunnel operation is enhanced.
