Multifunctional rail transit brake system and method

The invention discloses a multifunctional rail transit brake system and method, and belongs to the field of rail transit. The brake system is started, a controller controls the oil pressure of the hydraulic cylinder to increase to push the telescopic shaft of the hydraulic cylinder, and the brake pad and the rail reach certain pressure under the action of the oil pressure and generate friction toachieve brake parking. When the sensor detects that the brake pad and the rail reach a certain pressure, the sensor feeds back information to the controller, and the controller controls the oil pressure of the hydraulic cylinder to be unchanged. And the brake pad automatically resets after the brake system is stopped. Rail clamping wheels on the two sides of the hybrid power ladder truck make close contact with the rails, the rail clamping wheels automatically rotate along with running of the hybrid power ladder truck, and it is guaranteed that the hybrid power ladder truck can resist lateralmovement and overturning a
