Control method for train to enter emergency traction mode and train

A control method for a train to enter an emergency traction mode, comprising:

• detecting current emergency traction information;
• and
• controlling, in response to the current emergency traction information satisfying the condition of entering the emergency traction mode, a train to enter the emergency traction mode;
• wherein the current emergency traction information comprises an emergency traction hard-wired signal, and the detecting current emergency traction information comprises:
• controlling, in response to the emergency traction hard-wired signal being effective, a braking control system to enter the emergency traction mode;
• or
• controlling, in response to the emergency traction hard-wired signal being effective, a traction control system to enter the emergency traction mode;
• and wherein the current emergency traction information further comprises a rotation speed of a motor and a hard-wired signal from a driver controller, and before controlling the traction control system to enter the emergency traction mode, the method further comprises:
• adjusting the motor in response to the emergency traction hard-wired signal being effective, to reduce torque of the motor to 0;
• and
• controlling in response to detecting that the rotation speed of the motor being less than or equal to a preset threshold, and the hard-wired signal from the driver controller being a non-traction hard-wired signal, the traction control system to enter the emergency traction mode.

A train, comprising a traction control system, a driver controller, and a braking control system,

• wherein the traction control system is configured to:
• detect whether current emergency traction information satisfies a condition of entering an emergency traction mode;
• control, in response to the current emergency traction information satisfying the condition of entering the emergency traction mode, the train to enter the emergency traction mode;
• and
• receive a hard-wired signal sent by the driver controller, and perform a corresponding operation according to a type of the hard-wired signal;
• and
• wherein the braking control system is configured to:
• collect an emergency traction hard-wired signal from the driver controller;
• enter the emergency traction mode in response to the emergency traction hard-wired signal being effective;
• and
• wherein the driver controller comprises a front driver controller and a rear driver controller, the traction control system comprising a traction inverter, and the braking control system comprising a braking controller;
• wherein the current emergency traction information comprises the emergency traction hard-wired signal, a rotation speed of a motor, and a hard-wired signal from the driver controller, and the traction control system detects whether the current emergency traction information satisfies the condition of entering the emergency traction mode and is specifically configured to:
• adjust the motor in response to the emergency traction hard-wired signal being effective, to reduce torque of the motor to 0;
• and
• enter the emergency traction mode in response to detecting that the rotation speed of the motor is less than or equal to a preset threshold, and the hard-wired signal from the driver controller is a non-traction hard-wired signal,
• the non-traction hard-wired signal comprising at least one of a braking hard-wired signal and a coasting hard-wired signal.
