Embodiment 1

[0053] Such as figure 2 As shown, a hierarchical control method for vehicle emergency traction, comprising the following steps:

[0054] As a first step, try restarting the faulty device.

[0055] Power off, reset and restart the faulty equipment first, so as to solve the sporadic faults or temporary faults of most network system components in a targeted manner, so that the faulty equipment can quickly return to normal working status, reduce the number of times the vehicle enters emergency traction, and reduce the costs and security risks.

[0056] Each sub-equipment of the train network system is equipped with a corresponding power-off restart circuit.

[0057] In this embodiment, the hosts of the train network system are two hot-standby redundant ones, that is, when any host is normal, the system can work normally. When any host of the train network system is normal, but detects that another host or a certain sub-equipment is abnormal, the normal host will drive the corr...

Embodiment 2

[0090] An emergency traction hierarchical control system, including the following modules, cascaded actions between modules:

[0091] The first module is configured to reset and restart the faulty device;

[0092] The second module is configured to synchronously transmit the vehicle status and fault data to the ground control center, which will be on duty to control the vehicle to enter the emergency operation state;

[0093] The third module is configured to perform emergency traction, and control different subsystems of the vehicle to force into another working state, perform speed limit control on the traction system, and establish a hard-wired safety loop to monitor the vehicle status;

[0094] A fourth module is configured to de-energize the vehicle.

[0095] The cascading actions between the modules, the cascading action relationship is that when the nth module is unsuccessful or unable to operate, the n+1th module is put into action.

[0096] n is an integer greater t...

Embodiment 3

[0099] In one or more embodiments, a computer-readable storage medium is provided, in which a plurality of instructions are stored, and the instructions are suitable for being loaded by a processor of a terminal device and executing the emergency traction classification described in Embodiment 1 Control Method.

Abstract

The invention provides an emergency traction hierarchical control method, a storage medium, equipment, a network system and a rail vehicle, and the method comprises the following steps that: the method enters the next step if the execution of one step is invalid, and the power-off reset restart of fault equipment is carried out; the vehicle state and the fault data are synchronously transmitted toa ground control center on behalf of guarding, and the vehicle is controlled to enter an emergency operation running state; emergency traction is executed, different subsystems of the vehicle are controlled to enter another working state in a forced mode, speed limiting control is conducted on the traction system, and a hard wire safety loop is established to monitor the state of the vehicle; andthe vehicle is powered off. According to the invention, accidental faults of most network system components can be automatically solved, the intelligent level of a train is improved, the workload ofemergency fault processing of a driver is reduced, the driving order is ensured, and the reliability of the train is improved.

Description

technical field [0001] The disclosure belongs to the technical field of rail vehicle emergency traction control, and relates to an emergency traction hierarchical control method, a storage medium, equipment, a network system and a rail vehicle. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] At present, most rail vehicles are equipped with emergency traction mode, but no detailed usage scenarios and risk analysis have been carried out. According to the inventor's understanding, the current emergency traction mode is: when the vehicle stops abnormally, the driver directly turns on the emergency traction mode switch, shields the train network system, and uses hard wires to control the train operation. [0004] However, in the vast majority of cases, the train network system does not have a serious failure, and its control and protection fu...
