Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art fall within the protection scope of the present invention.

As shown in FIG. 1 , an automatic wind-release train braking system according to an embodiment of the present invention includes a control circuit system 1 and a wheel sensor 6 arranged on the rail. The control circuit system 1 is connected with a power supply 2 and a safety controller 4. The power source 2 is connected with the solar panel 3, the safety controller 4 is connected with the air release device 5, the safety controller 4 includes a signal converter 41, the signal converter 41 is connected with a parking button 42 through a line, and the signal converter 41 is connected with the control circuit system 1 is connected through a line, and the stop button 42 is connected with the venting device 5 through a line.

In a specific embodiment, the wheel sensor 6 is a magnetic sensor.

Preferably, the wheel sensor 6 is arranged on the rail at a distance of 20m from the vehicle stopper.

In a specific embodiment, the air releasing device 5 is arranged at the rear of each car.

In a specific embodiment, the voltage provided by the power supply 2 is 12V.

In a specific embodiment, the air venting device 5 is provided with an air exhaust valve 51 .

In a specific embodiment, the control circuit system 1 is provided with a warning light 11 and a sound and light alarm device 12 .
