Description

Technical Field

[0001] The present invention relates to the field of rail transportation, and in particular to a train fault processing method and system. Background Art

[0002] Urban rail transit is a public transportation tool that carries passengers on a large scale. It is also a very complex system that integrates and monitors numerous subsystems and equipment, including traction, braking, auxiliary machinery, running gear, air conditioning, fire alarms, pantograph detection, batteries, door control, etc. There are many parts. As the equipment ages, various faults will occur, resulting in train delays, cancellations, etc., affecting the normal operation of the subway and reducing the passenger service capacity.

[0003] At present, the handling of faults mainly relies on the coordination of the driver (man-driven) or vehicle dispatcher (unmanned), as well as the train dispatcher and station staff of the control center. The driver or vehicle dispatcher determines the current state of the train based on the prompts of the vehicle monitoring system, whether it is in a condition to continue driving or needs rescue, and notifies the dispatcher of the center that the vehicle has a fault and needs emergency treatment. The dispatcher determines the scope of the impact on the operation based on the feedback of the driver or vehicle dispatcher. For those who need rescue, they arrange for passenger removal and rescue. For those vehicles that are in a condition to continue driving, they arrange for the faulty vehicle to be cleared of passengers in time, withdraw from operation, and arrange for a spare vehicle to be put online to replace it. The operation of vehicle faults is very cumbersome, which increases the work pressure of dispatchers and reduces the efficiency of driving command. Summary of the invention

[0004] In order to improve the operating efficiency of rail transit, the present invention proposes a train fault processing method. The processing method comprises the following steps:

[0005] S1. Determine the corresponding processing category according to the fault type;

[0006] S2, transmit the fault to the automatic train monitoring system (ATS system) through the vehicle's signal interface;

[0007] S3, the train automatic monitoring system generates a specific processing plan based on the real-time incoming vehicle faults, combined with the factors around the vehicle and the vehicle fault line calculation according to the preset processing category;

[0008] S4. Issue an execution command according to the generated processing solution.

[0009] Furthermore, the processing categories include at least one of rescue, clearing passengers nearby, driver taking over, running to the current terminal to clear passengers, and running until the end of today's service.

[0010] Furthermore, for vehicle failures with a processing category of rescue, the following processing procedures are included: determining the location of the faulty vehicle, finding the nearest stop line, determining the corresponding passenger clearance platform, as well as the rescue train and the passenger clearance platform of the rescue train, and forming a passenger clearance and rescue order.

[0011] Furthermore, for vehicle failures with the processing category of nearby passenger clearance, the following processing procedures are included: determining the location of the faulty vehicle, finding the nearest passenger clearance platform, finding a spare vehicle, determining the planned train number for the spare vehicle to replace it, and generating commands to take the faulty vehicle offline and replace it with the spare vehicle.

[0012] Furthermore, for vehicle failures that require driver takeover, the following processing procedures are included: the faulty vehicle is automatically detained at a station where the driver can board, the central dispatching personnel are proactively notified of the failure and the scope of impact of the operating vehicle, and the dispatching personnel are prompted to arrange for the driver to board in a timely manner.

[0013] Furthermore, for the vehicle failure processing category of running to the current terminal, the following processing process is included: determining the location of the faulty vehicle and the terminal of this run, finding a spare vehicle, determining the planned train number for the spare vehicle to replace it, and generating commands to take the faulty vehicle offline and the spare vehicle to replace it.

[0014] Furthermore, for vehicle failures whose processing category is running until the end of the day's service, the following processing process is included: actively reminding the central dispatching personnel of the failure and the scope of impact of the operating vehicle, and the dispatching personnel handle it as needed.

[0015] Furthermore, the spare vehicle is a spare vehicle at a terminal station serving the faulty vehicle.

[0016] Furthermore, step S1 also includes establishing a mapping table corresponding to fault types and processing categories.

[0017] Furthermore, step S2 also includes the vehicle sending a status code to the train automatic monitoring system in real time, and step S3 determines the train fault condition according to the status code.

[0018] In addition, the present invention also provides a train fault processing system for executing the processing method, comprising:

[0019] A train having a signal interface, wherein the train sends a fault code bit through the signal interface;

[0020] A train automatic monitoring system, which is in communication with the train via the signal interface, and is used to receive fault code bits and generate corresponding execution commands;

[0021] The dispatching center is connected to the automatic train monitoring system for receiving execution commands.

[0022] The present invention has the following beneficial effects:

[0023] 1. Map a wide variety of faults to several categories related to operational adjustments, and establish a corresponding relationship between faults and processing categories. By identifying the fault code, the processing plan can be calculated, which can guide dispatchers to promptly understand the impact of equipment failures on operations, greatly improving the efficiency of dispatchers in handling vehicle failures;

[0024] 2. Added multiple intelligent commands for one-click delivery and disposal. Through automatic calculation and recommendation, a composite intelligent command is generated to replace the multiple commands that the original dispatcher needed to execute at different time points in the processing stage, which greatly improved the disposal efficiency and reduced the work pressure of dispatchers.

[0032] S4. Issue an execution command according to the generated processing solution.

[0033] Furthermore, in step S3, for vehicle faults with the rescue category, such as total air undervoltage faults, the following processing procedures are included: determine the location of the faulty vehicle, and find the nearest stop line according to the rules, such as preferentially searching in the forward running mode, but in special areas, such as the line terminal, it can be determined according to special configuration rules. Determine the corresponding clearing platform, and determine the clearing platform of the rescue train and the rescue train, and form a clearing rescue command.

[0034] Furthermore, in step S3, for vehicle failures with the processing category of clearing passengers nearby, such as failures of two or more traction inverters, the following processing procedures are included: determining the location of the faulty vehicle, finding the nearest platform for clearing passengers, if the vehicle happens to be parked at the platform, clearing passengers at the platform, finding a spare vehicle, giving priority to spare vehicles at the terminal served by the faulty vehicle, determining the planned train number for the spare vehicle to replace it, and generating commands for taking the faulty vehicle offline and for the spare vehicle to replace it.
