DETAILED DESCRIPTION

[0021] The concept, specific structure and technical effects of the present invention will be clearly and completely described below in conjunction with the embodiments and drawings to fully understand the purpose, characteristics and effects of the present invention.

[0022] Example 1 A TACS artificial vehicle resource reduction and protection method based on beacon location, such as Figure 1-Figure 5 As shown, the present invention proposes a TACS manual vehicle resource reduction and protection method based on beacon position: according to the beacon position, the manual vehicle safety position is calculated, the manual vehicle holding resource area is reduced using the safety position tail, and it is determined whether the train is advancing recklessly or sliding backward, and the train unexpected movement alarm information is sent to the automatic train supervision (ATS, Automatic Train Supervision) and the wayside resource manager (WRC, Wayside Resource Controller).

[0023] The present invention can be implemented by the following technical solutions: First, make sure that the TACS system has switched to the backup system to control the vehicle.

[0024] Step S1, ATS issues a task from platform 1 to platform 2, WTC accepts the task and calculates the manual vehicle resource holding area.

[0025] The task issued by the ATS in step S1 includes the operating range from platform 1 to platform 2. The WTC manual vehicle calculates the area of ​​the corresponding resources to be used, requests the resources and locks them. Subsequent vehicles can no longer apply for resources in this area.

[0026] Step S2: Calculate the train safety positioning area based on the collected beacon positions, and determine whether the beginning of the safety positioning area in the same direction as the train travels crosses the artificial vehicle resource holding area. If so, identify the train's reckless advance and send warning information to ATS and WRC. If not, proceed to the next step.

[0027] In step S2, the starting end END1 of the safety positioning area in the same direction as the train is used to compare with the current manual vehicle holding area range. If END1 crosses the area, Figure 3 As shown, it can be determined that the train is advancing recklessly, and the information needs to be sent to ATS and WRC to lock the corresponding area to prevent other vehicles from entering.

[0028] The implementation details of step S2 are: Step S2.1, collecting the beacon position; Step S2.2, extending the maximum half of the vehicle length forward and backward according to the beacon position; Step S2.3: Based on step S2.2, the front and rear extension beacon installation error distances are the same as the train travel direction as END1 position, and the opposite direction of the train travel direction as END2 position, such as Figure 2 and 3 As shown; Step S2.4, using the END1 position to compare with the manual vehicle resource holding area range; Step S2.5, if the END1 position exceeds the manual vehicle resource holding area, Figure 3 As shown, the train is identified to be intruding, and the warning protection information is sent to ATS and WRC; Step S2.6: Return to step S2.4. If the END1 position is still within the manual vehicle resource holding area, proceed to the next step.

[0029] Step S3: Calculate the train safety positioning area based on the collected beacon positions, and determine whether the end of the safety positioning area opposite to the train's travel direction crosses the artificial vehicle resource holding area. If so, identify the train slipping and send the alarm information to ATS and WRC. If not, proceed to the next step.

[0030] In step S3, the end END2 of the safety positioning area opposite to the train driving direction is used to compare with the current manual vehicle holding area range. If END2 crosses the area, Figure 4 As shown, it can be determined that the train is slipping backwards, and this information needs to be sent to ATS and WRC to lock the corresponding area to prevent other vehicles from entering.

[0031] The implementation details of step S3 are: Step S3.1, collecting the beacon position; Step S3.2, extending the maximum half of the vehicle length forward and backward according to the beacon position; Step S3.3: Based on step S3.2, the front and rear extension beacon installation error distances are the same as the train travel direction as END1 position, and the opposite direction of the train travel direction as END2 position, such as Figure 2 and 4 As shown; Step S3.4, using the END2 position to compare with the manual vehicle resource holding area range; Step S3.5, if the END2 position is beyond the range of the manual vehicle resource holding area, such as Figure 4 As shown, the train is identified to slip backwards, and the warning protection information is sent to ATS and WRC; Step S3.6: Return to step S3.4. If the END2 position is still within the manual vehicle resource holding area, proceed to the next step.

[0032] Step S4: Calculate the train safety positioning area according to the collected beacon positions, use the end positioning position of the safety positioning area opposite to the train's travel direction, and reduce the scope of the manual vehicle holding area.

[0033] In step S4, the end END2 of the safety positioning area opposite to the train driving direction is used to compare with the current manual vehicle holding area range, and the tail of the area is reduced to the END2 position to release the resources of the area that the train has passed. Figure 5 shown.

[0034] The implementation details of step S4 are: Step S4.1, collecting the beacon position; Step S4.2, extending the maximum half of the vehicle length forward and backward according to the beacon position; Step S4.3, based on step S4.2, the front and rear extension beacon installation error distances are set to the END1 position in the same direction as the train's travel direction, and the END2 position in the opposite direction to the train's travel direction; Step S4.4, using the END2 position to compare with the manual vehicle resource holding area range; Step S4.5: Reduce the tail of the area range held by the manual vehicle resources to the END2 position, and release the resources in the area where the train has passed.

[0035] The overall process includes ATS issuing tasks, WTC calculating the range of the manual vehicle resource holding area, and calculating the train safety positioning area based on the location of the collected beacon. Compare the train safety positioning area with the manual vehicle resource holding area to determine whether the train is advancing or sliding backward. If so, send the alarm protection information to ATS and WRC. If not, reduce the range of the manual vehicle resource holding area based on the train safety positioning area and release the resources in the area where the train has passed.
