It should be noted that, taking example 1 as an example, while the rail vehicle is running, the state data of the rail vehicle, including, but not limited to, the emergency brake control circuit breaker state, is monitored in real time. When the emergency braking of the railway vehicle is determined, the condition of the emergency braking control circuit breaker is determined to be abnormal based on the acquired condition data, and the emergency braking control circuit breaker is tripped, so that the reason for braking the railway vehicle can be determined to be that the emergency braking control circuit breaker is tripped at the cab occupation end.
In this scheme, the status data collected in real time may be current and voltage at a certain position in the circuit, status information of a certain device in the circuit, status information of a certain corresponding device of the rail vehicle, and the like, and may be specifically set according to actual requirements, which is not limited in the present invention.
Secondly, in the actual running process of the rail vehicle, the condition for triggering the emergency braking of the rail vehicle is not limited to the above 10 examples, but other conditions exist, the above example is only used as a specific example to explain the method provided by the present invention, and the specific state data and the corresponding fault cause can be adjusted according to the actual situation, which is not limited by the present invention.
The rail vehicle emergency braking diagnosis method provided by the invention determines the rail vehicle state data to be acquired according to the corresponding relation through the pre-established corresponding relation between the rail vehicle state data and the rail vehicle emergency braking reason, and can quickly and accurately determine the reason of the rail vehicle emergency braking when the rail vehicle emergency braking occurs by combining the rail vehicle state data acquired in real time and the corresponding relation between the rail vehicle state data and the rail vehicle emergency braking reason, so that a driver can take emergency treatment measures in time, the time for processing the train emergency braking fault is reduced, and the potential safety hazard is reduced.

and determining the reason for relieving the emergency braking abnormity of the railway vehicle according to the corresponding relation between the preset railway vehicle state data and the reason for relieving the emergency braking abnormity of the railway vehicle on the basis of the railway vehicle state data.
Specifically, after the emergency braking of the railway vehicle, after the fault corresponding to the emergency braking reason is solved, the emergency braking of the railway vehicle is relieved. However, in the actual running process of the rail vehicle, emergency braking of the rail vehicle is already relieved under the condition that the fault is not eliminated due to some special reasons, and the emergency braking abnormal relieving condition of the rail vehicle causes uncertainty of the running state of the rail vehicle and potential safety hazards.
Therefore, besides the reason when the rail vehicle is emergently braked, the running state of the rail vehicle needs to be monitored in real time, and the problem that whether the rail vehicle is emergently braked or not can be found in time, but the emergency brake is abnormally relieved due to some reasons is guaranteed.

In the present embodiment, the correspondence relationship between the rail vehicle state data and the cause of emergency braking abnormality relief of the rail vehicle is determined based on the reason why the rail vehicle should perform emergency braking based on the cause of failure during actual traveling, but when emergency braking does not occur, the cause of emergency braking abnormality relief and the change in the state data. It can be determined in reverse that when some indexes in the state data change, the rail vehicle should be emergently braked due to some reason, but the emergency brake is abnormally relieved. Specifically, the corresponding relationship between the state data and the reason for alleviating the emergency braking anomaly may be set according to the actual situation, which is not limited in the present invention.
