[0019] In this disclosure, the automatic train monitoring system receives meteorological information from a weather station and determines the weather type and severity based on the information. It then adjusts the train operation mode accordingly. The adjusted train operation status is then sent to the passenger information display system and / or the broadcasting system, allowing the passenger information display system and / or the broadcasting system to inform passengers of the adjusted train operation status. This enables rapid acquisition of accurate meteorological information, reduces safety risks during train operation in severe weather, ensures safe operation, reduces manual intervention, improves train operation efficiency, reduces the workload of operating personnel, and enhances passenger service quality.

[0020] The Automatic Train Supervision (ATS) system is a core subsystem of the Automatic Train Control System and the Train Operation Control System. It achieves global supervision and control of train operation through a distributed real-time computer system.

[0021] Automatic Train Protection (ATP) is a core component of urban rail transit signaling systems. It is primarily used to ensure train operation safety and prevent train speeding, collisions, and other dangerous situations.

[0022] The ATS system comprises: ATS front-end equipment, ATS back-end equipment, and ATS external interface equipment. The ATS front-end equipment consists of a dispatch workstation, through which personnel control trains (e.g., reducing speed, stopping trains at stations, or preventing trains from stopping at platforms). The ATS back-end equipment includes application servers and database servers, used to store and process ATS system data. The ATS external interface equipment consists of communication front-end units, used for data exchange with external professionals.

[0023] The weather station sends weather information to the ATS system; the passenger information display system displays train arrival and departure times; the public address system broadcasts information such as train arrival and departure times and train accidents. ATP (Automatic Train Protection) equipment is used for train safety protection; onboard equipment ensures safe train operation; firewall equipment prevents viruses from external sources from infiltrating the signaling system.

[0024] Figure 1A flowchart of a train scheduling method 100 based on meteorological information according to an embodiment of the present disclosure is shown. Method 100 includes: S101 receives meteorological information sent by the meteorological station, determines the meteorological type and the severity of the weather based on the meteorological information, sets corresponding control commands based on the severity of the weather, sends the control commands to the train automatic protection system, so that the train automatic protection system executes the control commands, and feeds back the execution results to the train automatic monitoring system. In one possible implementation, the weather type includes strong winds, rain, and snow.

[0025] In one possible implementation, determining severe weather conditions includes: If the wind speed is greater than the first preset threshold and less than the second preset threshold and / or the amount of rain and snow within a preset time period is greater than the third preset threshold and less than the fourth preset threshold, then the weather condition is the first severe condition. If the wind speed is greater than or equal to the second preset threshold and / or the amount of rain and snow within a preset time period is greater than or equal to the fourth preset threshold, then the weather condition is the second most severe condition.

[0026] For example, if 20 m / s < wind speed < 29 m / s and / or 15 mm < snowfall < 30 mm within 12 hours, then the weather condition is the worst possible.

[0027] In one possible implementation, if the wind speed is greater than a first preset threshold and less than a second preset threshold, a temporary speed limit command is automatically set and sent to the train automatic protection system. The train automatic protection system receives the temporary speed limit command and sends it to the onboard subsystem. The onboard subsystem controls the train to stop at the station platform closest to the current position. After the train restarts, the temporary speed limit command is executed, and a success message is sent to the train automatic monitoring system.

[0028] For example, when the wind speed is less than 20 m / s and less than 29 m / s, the ATS system automatically sets a temporary speed limit command of 25% below the maximum operating speed and sends the temporary speed limit command to the ATP system. The ATP system sends the temporary speed limit command to the onboard subsystem. After receiving the temporary speed limit command, the onboard subsystem controls the train to stop at the platform of the station closest to its current location. After the train restarts, it executes the temporary speed limit command and sends a message indicating that the temporary speed limit command was successfully executed to the ATS system.

[0029] In one possible implementation, if the wind speed is greater than or equal to a second preset threshold, a temporary speed limit command and a train operation route command to the depot are automatically set. The timetable workstation loads the depot route according to the operation route command. The temporary speed limit command and the depot return route are sent to the train automatic protection system. The train automatic protection system accepts the above instructions and sends them to the onboard subsystem. The onboard subsystem controls the train to change the depot return route and stops at the platform of the station closest to the current position. After the train restarts, the temporary speed limit command is executed, and the information of successful execution of the temporary speed limit command and successful change of the depot return route is sent to the train automatic monitoring system.

[0030] For example, when the wind speed is greater than 29 m / s, the ATS subsystem automatically sets a temporary speed limit command of no more than 8 m / s above the ground. At the same time, it automatically sets a running route command for the train to automatically run to the depot and loads the return route to the depot according to the running route command. The ATS system sends the temporary speed limit command and the return route to the depot to the ATP system. The ATP system sends the above commands to the onboard subsystem. The onboard subsystem controls the train to change the return route to the depot and stop at the platform of the station closest to the current position. After the train restarts, it executes the temporary speed limit command and sends the information that the temporary speed limit command was executed successfully and the information that the return route to the depot was changed successfully to the ATS system.

[0031] In one possible implementation, if the rainfall or snowfall within a preset time period is greater than a third preset threshold but less than a fourth preset threshold, a temporary speed limit command, a train braking rate command, and a train quantity command for the control section are automatically set, and the timetable workstation reloads the timetable. The temporary speed limit command, train braking rate command, train quantity command for the control section, and the reloaded timetable are sent to the automatic train protection system. The automatic train protection system accepts the above instructions and sends them to the onboard subsystem. The onboard subsystem controls the train to execute the train quantity command for the control section and adjusts its operation according to the reloaded timetable, stopping at the platform of the station closest to the current position. After the train restarts, it executes the temporary speed limit command and the train braking rate command, and sends a success message to the automatic train monitoring system.

[0032] For example, when the rainfall / snowfall is less than 15mm (within 12 hours) and less than 30mm (within 12 hours), the ATS system automatically sets a temporary speed limit command of 25% lower than the maximum operating speed, and the train braking rate is no greater than 0.4m / s. 2The system sends the train braking rate command and the number of trains in the controlled section (the number of trains in the section shall not exceed 2) to the ATP system. At the same time, the timetable workstation automatically loads the new timetable. The ATS system sends the temporary speed limit command, the train braking rate command, the number of trains in the controlled section command, and the reloaded timetable to the ATP system. After receiving the command from the ATS system, the ATP system sends the above commands to the onboard subsystem. The onboard subsystem controls the train to adjust its operation according to the new timetable (if there are two trains in the section, the following train will automatically brake to a stop until the preceding train clears the section) and stop at the platform of the station closest to the current position. After the train starts, it executes the temporary speed limit command and the braking rate command and sends the command execution success information to the ATS system.

[0033] In one possible implementation, if the amount of rain and snow within a preset time period is greater than or equal to a fourth preset threshold, then the temporary speed limit command, the train braking rate command, and the train quantity command for the control section are maintained, and a train operation route command for automatic operation to the depot is set. The timetable workstation loads the depot return route according to the operation route command; the depot return route is sent to the train automatic protection system, and the train automatic protection system sends the depot return route to the onboard subsystem; the onboard subsystem controls the train to change the depot return route and sends the depot return route change success information to the train automatic monitoring system.

[0034] For example, when the rainfall or snowfall exceeds 30mm within 12 hours, the ATS subsystem maintains the temporary speed limit command, braking rate command, and train quantity control command for the control section, and automatically sets the running route command for trains on the line to automatically run to the depot; the ATS system sends the return route to the depot to the ATP system; the ATP system forwards the above command to the onboard subsystem, the onboard subsystem controls the train to automatically change the return route to the depot according to the return route, and sends the return route change success information to the ATS system.

[0035] In one possible implementation, the train quantity command for the controlled section includes: the number of trains in the controlled section shall not exceed 2. In one possible implementation, adjusting the operation according to the reloaded operation chart includes: when there are two trains in the section, the train behind brakes and stops until the train in front clears the section.

[0036] In one possible implementation, the weather station sends daily weather information, such as temperature, wind speed, wind direction, rainfall / snowfall, and duration, to the ATS system via an external interface device. The ATS system adjusts train operation modes according to different weather conditions, such as automatically setting temporary speed limits, impounding trains at station platforms, or decommissioning trains for maintenance. Simultaneously, the adjusted train operation modes are sent to the station's passenger information display system and / or broadcasting system via the external interface device.

[0037] S102 sends the adjusted train operation status to the passenger information display system and / or broadcasting system.

[0038] In one possible implementation, the adjusted train operation status includes: train early departure information, train late departure information, and train decommissioning information.

[0039] In one possible implementation, the ATS system sends train operation information, such as train arrival and departure times and train decommissioning information, to the station passenger information display system and broadcasting system via external interface devices. This information is then displayed on passenger screens on the platform, and the station broadcasting system promptly broadcasts train information to passengers.

[0040] For example, the ATS system receives windy weather and wind speed information from the weather station; when the wind speed is less than 20 m / s, the train maintains its current operating speed without any action; when 20 m / s < wind speed < 29 m / s, the ATS system automatically sets a temporary speed limit command (25% lower than the maximum operating speed) and sends the temporary speed limit command to the ATP system; after receiving the temporary speed limit command, the ATP system sends it to the onboard subsystem, which controls the train to stop at the platform of the station closest to its current location; after the train restarts, the temporary speed limit command is executed, and a message indicating successful execution of the temporary speed limit command is sent to the ATS system; after receiving the successful execution message, the ATS system sends the temporary speed limit information and train delay information to the station passenger information display system and the broadcast system; the passenger information display system displays the train delay information, and the broadcast system broadcasts the train temporary speed limit information. When the wind speed exceeds 29 m / s, the ATS subsystem automatically sets a temporary speed limit command of no more than 8 m / s above the ground. Simultaneously, it automatically sets a route command for the train to automatically return to the depot. The timetable workstation loads the return route to the depot based on this command. The ATS system sends the temporary speed limit command and the return route to the ATP system, which in turn sends them to the onboard subsystem. The onboard subsystem controls the train to change its return route to the depot and stops at the platform of the nearest station. After the train restarts, it executes the temporary speed limit command and sends a message indicating successful execution of the temporary speed limit command and successful change of the return route to the depot back to the ATS system. Upon receiving these messages, the ATS system sends the temporary speed limit information and train decommissioning information to the station passenger information display system and the public address system. The passenger information display system displays train delay information and information about the train's impending decommissioning, while the public address system broadcasts the temporary speed limit information and the train's impending decommissioning information.

[0041] For example, the ATS system receives rain and snow weather information and the amount of rain and snow within 12 hours from the weather station; when the amount of rain and snow is less than 15mm (within 12 hours), the train maintains its current operating speed without any action. When 15mm (within 12 hours) < amount of rain and snow < 30mm (within 12 hours), the ATS system automatically sets a temporary speed limit command (below 25% of the maximum operating speed) and a train braking rate command (train braking rate not greater than 0.4m / s). 2 The system sends commands to control the number of trains in a given section (no more than two trains per section), and the timetable workstation automatically loads the new timetable. The ATS system sends temporary speed limit commands, train braking rate commands, commands to control the number of trains in a given section, and the reloaded timetable to the ATP system. After receiving the commands from the ATS system, the ATP system sends them to the onboard subsystem, which controls the train to adjust its operation according to the new timetable (if there are already two trains in a section, the following train will automatically brake to a stop until the preceding train clears the section), and stops at the platform of the station closest to the current position. After the train starts, it executes the temporary speed limit commands and braking rate commands, and sends a message of successful command execution to the ATS system. After receiving the message of successful command execution, the ATS system sends the temporary speed limit information and train delay information to the station passenger display information system and the broadcast system. The passenger information display system displays the train delay information, and the broadcast system broadcasts the temporary speed limit information. When the rainfall or snowfall exceeds 30mm (within 12 hours), the ATS subsystem maintains the temporary speed limit command, braking rate command, and train quantity command for the controlled section, while automatically setting the running route command for trains on the line to automatically run to the depot; the timetable workstation reloads the timetable and sends it to the onboard subsystem; the onboard subsystem controls the train to automatically change the return route to the depot according to the return route, and sends the return route change success information to the ATS system; after receiving the return route loading success information, the ATS system continuously sends the temporary speed limit information and train decommissioning service information to the station passenger information display system and the broadcast system. The passenger information display system displays train delay information and train decommissioning service information, and the broadcast system broadcasts the temporary speed limit information and train decommissioning service information.
