Embodiment 1
[0018] According to an embodiment of the present invention, an embodiment of a method for controlling the deicing of an EMU is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.
[0019] figure 1 It is a flow chart of a method for controlling deicing of multiple train units according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:
[0020] Step S102 , when the EMU receives the snow resistance braking instruction, detect the current working state of the EMU.
[0021] Specifically, the EMU can determine whether to generate a snow-resistant braking command through the position of an operation knob switch.

Embodiment 2
[0087] According to an embodiment of the present invention, an embodiment of a device for controlling deicing of an EMU is provided.
[0088] Figure 4 is a schematic diagram of a device for controlling the deicing of multiple trains according to an embodiment of the present invention, as Figure 4 As shown, the device includes:
[0089] The detection module 41 is configured to detect the current working state of the EMU when the EMU receives the snow-resistant braking instruction.
[0090] Specifically, the EMU can judge whether a snow-resistant braking instruction is received through the position of an operation knob switch.
[0091] In an optional solution, when the knob switch is at the "apply" position, the EMU receives a snow resistance command, and the detection module automatically detects the vehicle status and ambient temperature, and judges whether the braking mode to be applied is deicing braking or snow resistance brake.
[0092] The judging module 43 is used ...
Embodiment 3
[0136] According to an embodiment of the present invention, an embodiment of an EMU is provided, including any device in Embodiment 2 for controlling the deicing of the EMU.
[0137] It should be noted here that the EMUs provided by this application include various preferred and optional embodiments of the device for controlling the deicing of EMUs provided in Embodiment 2 above, but are not limited to the embodiments provided in Embodiment 2 .
[0138] The serial numbers of the above embodiments of the present invention are for description only, and do not represent the advantages and disadvantages of the embodiments.

Abstract
The invention discloses a method and device for controlling a motor train unit to deice and a motor train unit. The method comprises the following steps of detecting the current working state of the motor train unit when the motor train unit receives a snow resistant braking instruction; judging whether a braking parameter of the motor train unit satisfies a preset braking condition or not when the current working state of the motor train unit is a traction working condition; and controlling to apply braking forces to braking discs of any one or more marshaled vehicles included in the motor train unit when the braking parameter of the motor train unit satisfies the preset braking condition. According to the invention, a technical problem that the motor train unit cannot be controlled to remove the ice and snow in time because a scheme for removing ice and snow between braking clamp disc sheets of the motor train unit in the prior art can only act upon the braking working condition is solved.
Description
technical field [0001] The invention relates to the field of EMUs, in particular to a method and device for controlling deicing of EMUs and EMUs. Background technique [0002] At present, domestic EMUs are widely used in various regions. For EMUs operating in cold northern regions, when it snows in winter, the brake clamps of the EMU bogies often have a lot of snow. The distance between the stops is long, and the brakes are not applied for a long time, which may cause ice and snow to accumulate between the brake disc and the brake pad. [0003] At present, it is only possible to rely on the application of air brakes, and the frictional heat generated by the air brakes can remove ice and snow between the discs. The existing EMUs only include one snow-resistant braking mode, and all vehicles in the formation apply braking force at the same time, and it can only work under braking conditions. [0004] Aiming at the problem that the existing technology for removing ice and sno...
