In particular, the aerodynamic braking device may generate a large braking force or a sudden change in the braking force on a train during high-speed traveling or when entering a tunnel, which may significantly reduce the safety of passengers and the vehicle body and damage the vehicle body. Therefore, it is desired to control the braking force of the aerodynamic braking device because it is expected that the influence of

Conventionally, an aerodynamic brake control device for controlling the braking of this type of aerodynamic brake device determines the braking force of the aerodynamic brake device based on speed information and train position information transmitted from ground facilities, and the Passing control is performed in which braking control is performed by changing the opening / closing angle.

As shown in FIG. 2C, when 80% of the braking force is applied to the aerodynamic braking means 6, the aerodynamic braking means 6 of each of the vehicles 1b and 1d of the five-car train is 1/1.
2, the aerodynamic braking means 6 of each of the other vehicles 1a, 1c, 1e is fully braked to apply a braking force of 80%.

On the other hand, when controlling the aerodynamic braking means as an emergency brake, the measuring device installed in the aerodynamic braking control means 4 of the first vehicle 1a measures the speed of the vehicle and the like. The signal is transmitted to the aerodynamic brake control means 4, and the aerodynamic brake control means 4 operates the aerodynamic brake operating means 5 to operate the aerodynamic brake means 6. At this time, as described above, in order to operate each aerodynamic braking means 6 as an emergency brake for the entire train,
The aerodynamic braking means 6 of all the vehicles 1a, 1b, 1c, 1d, 1e of the five-car train is selectively erected and operated stepwise.

As described above, the present invention is intended to improve the safety and reliability of the train for emergency braking while reducing the weight of the magnetic levitation train.

Next, FIGS. 3A, 3B and 3C and FIG.
