Background
For example, an execution unit of a brake system of a common motor train unit comprises a brake disc and a brake pad, which are respectively arranged on a wheel structure of each compartment of the motor train unit, and when the brake system sends a braking instruction, a braking instruction electric signal of the brake system is converted into compressed air with certain pressure through an automatic braking control unit so as to urge the brake disc and the brake pad to be attached to each other, so as to generate a braking force required by the wheels.
However, the braking system of the motor train unit cannot be well used on roads covered by ice and snow, for example, in rainy days or snowy days, when the motor train runs fast, rain or ice and snow are carried between the brake disc and the brake pad, and if the rain between the brake disc and the brake pad freezes, the braking force generated by the brake disc and the brake pad is small, so that the braking resistance acting on the train is reduced, the braking distance of the motor train is lengthened, and the operation of the motor train is unsafe. The existing solution can only be realized by a driver or a related operator operating a brake handle connected with a brake system according to actual experience to generate a proper braking force so as to remove ice between each brake disc and each brake pad, thereby ensuring the safety and reliability of the train during subsequent braking. That is to say, a driver can operate the brake handle to generate a slight braking force to remove ice between the brake disc and the brake pad, the operations depend on actual control skill and experience of the driver, the train generates unnecessary impulse and redundant abrasion due to the overlarge braking force, the purpose of removing the ice and snow between the brake disc and the brake pad cannot be achieved due to the too small braking force, and further the safe braking of the later-stage motor train unit cannot be ensured.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, 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, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 shows a schematic structural diagram of an embodiment of a deicing device for a rail transit vehicle braking system according to the present invention; the control panel 101 is arranged in a control chamber of the rail transit vehicle braking system, and the control panel 101 is connected with the braking system and used for sending a signal to enable the braking system to generate a first braking force for braking the rail transit vehicle. Specifically, the brake handle unit 103 integrated on the control panel 101 is connected to the brake system, so that the driver can operate the brake handle unit 103 to make the brake system generate a first braking force, thereby better stopping or slowing down the rail transit vehicle. In this embodiment, the control panel 101 is provided with a clearing unit 102, and the clearing unit 102 is connected to the brake system and is used for sending a signal to enable the brake system to generate a second braking force for clearing the ice and snow in the execution unit, and when the designated units are a brake disc and a brake pad, the second braking force is used for clearing the ice between the brake disc and the brake pad of the railway vehicle. When the ice and snow between the brake disc and the brake pad of the brake system of the rail transit vehicle are actually removed, the second braking force generated by the brake system controlled by the removing unit can be smaller than the first braking force. Of course, the magnitude of the second braking force is mainly set according to the actual environment of the motor car and the structure of the motor car, and the specific magnitude is not limited in this embodiment. Generally, the first braking force can be set to several levels so as to select different levels to perform quick or slow braking on the vehicle, so that different braking commands can be set for different braking systems in the embodiment, for example, when the execution unit connected with the braking system is a brake cylinder or a brake clamp, the second braking force can be variably set so that the motor cars in different environments can effectively clear ice between the brake disc and the brake pad.
Preferably, the clearing unit in this embodiment may be a button mounted on a control panel of the brake system. That is, a button for changing the braking mode of the braking system is added on the control panel, and when the button is pressed, the braking system is in the clearing mode of the deicing device, namely, the first control unit of the braking system sends out a corresponding braking instruction, so that the automatic braking control unit, namely, the second control unit executes the braking instruction; when the button is released, the brake system exits the clear mode. It should be noted that the brake command and the signal mentioned in this embodiment are the same, and for the convenience of description, a part of the brake command description and a part of the signal description are used.

The first control unit 202 is configured to receive an action command of a driver operating the driver handle 201 (the action command includes a command of a clear mode), and then the first control unit 202 sends a signal corresponding to the action command of the driver handle 201 (for example, when the action of the driver handle 201 is a clear action command, the first control unit 202 sends a signal corresponding to the second braking force); this signal is transmitted via the on-board network 203 to an automatic braking control unit which is adapted to receive and convert the signal corresponding to the second braking force; and enabling the execution unit to execute the converted signal and clear the ice and snow in the execution unit. When the execution units are the brake disc and the brake pad, the brake system generates a second braking force, so that the execution units of the rail transit vehicle are in a clearing mode, and the ice and snow between the brake disc and the brake pad of the brake system of the rail transit vehicle are cleared. Fig. 2 schematically shows respective automatic brake control units and corresponding execution units thereof, such as an automatic brake control unit 204 of a first car and a corresponding execution unit 205 of the first car, an automatic brake control unit of a second car and a corresponding execution unit of the second car, or an automatic brake control unit of an nth car and a corresponding execution unit of the nth car, and the like, in a rail transit vehicle.
