[0058] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0059] It should be noted that the train control method proposed in this embodiment is applied to the train control system, such as... Figure 1 As shown, the train control system includes the Train Operation Automation System (TIAS), the Driver Assistance Equipment (AOM), and the Onboard Driver Assistance System (ATP). The AOM subsystem includes a first AOM and a second AOM deployed at both ends of the train. The ATP subsystem includes a first ATP and a second ATP deployed at both ends of the train. The first AOM and the first ATP are deployed at the front of the train, while the second AOM and the second ATO are deployed at the rear of the train. These subsystems work together to ensure the safe and efficient operation of the train.

[0060] The following is combined Figure 2 A train control method according to the present invention includes:

[0061] Step 101: If the first AOM does not establish a communication connection with the TIAS subsystem within the preset power-on working time of the first AOM, and the ID of the first AOM is odd, then the first AOM is determined to be the active end.

[0062] It should be noted that the activating end typically refers to a device or node that actively initiates communication or control, responsible for sending control commands or providing services. Generally, after a train is powered on, since power supply usually starts from the front of the train and gradually moves towards the rear, the activated device is usually the one at the front of the train.

[0063] In this embodiment, the first AOM's ID is an odd number, indicating that it is a device deployed at the head of the train. If the first AOM deployed at the head of the train has a preset power-on working time (e.g., 7 or 5 seconds, which can be flexibly configured) and it is detected that the second AOM at the other end has not established a communication connection with the TIAS subsystem, then the first AOM is the default active end. The first AOM establishes communication with the TIAS subsystem and works together to ensure the safe and efficient operation of the train.

[0064] Step 103: Obtain train status information, and perform activation terminal conversion between the first AOM and the second AOM based on the train status information;

[0065] The train status information includes the following aspects:

[0066] Communication status between the first AOM and the TIAS subsystem;

[0067] Communication status between the first AOM and the second AOM;

[0068] Communication status between the first AOM and the first ATP;

[0069] Communication status between the second AOM and the TIAS subsystem;

[0070] The communication status between the second AOM and the second ATP;

[0071] At least one of the communication states between the first ATP and the second ATP.

[0072] In this embodiment, any abnormality in any of the above states may lead to a change in the active endpoint. Based on the train status information, the AOM can determine which AOM should become the active endpoint and switch it accordingly. For example, if the communication status between the first AOM and the TIAS subsystem is abnormal, the system may switch the active endpoint to the second AOM to ensure the safety and reliability of train operation.

[0073] Specifically, to achieve head-to-tail redundancy, the first and second AOMs of the AOM subsystem will transmit head-to-tail communication information to each other under normal communication conditions. This head-to-tail communication information includes: connection status with TIAS, local AOM operating status, local AOM IO acquisition status, wake-up command sending status, hibernation command sending status, local ATP communication status, local ATP activation status, local AOM activation status, hibernation command, wake-up command, train hibernation / wake-up status, wake-up failure reason, hibernation failure reason, hibernation health status, wake-up VOBC self-test completion, power-on status, whether hibernation is allowed, whether wake-up is allowed, hibernation procedure, and wake-up procedure. The above train status information can be obtained through the head-to-tail communication information transmitted between the first and second AOMs.

[0074] This embodiment determines the first AOM as the active endpoint when, within a preset power-on operating time, no communication connection is established between the first AOM and the TIAS subsystem, and the ID of the first AOM is odd. Train status information is acquired, and an active endpoint switch is performed between the first AOM and the second AOM based on this information. The train status information includes at least one of the following: the communication status between the first AOM and the TIAS subsystem; the communication status between the first AOM and the second AOM; the communication status between the first AOM and the first ATP; the communication status between the second AOM and the TIAS subsystem; the communication status between the second AOM and the second ATP; and the communication status between the first ATP and the second ATP. Therefore, by monitoring the train status information, the communication status between each subsystem can be understood in real time, anomalies can be detected promptly, and a rapid response and active endpoint switch can be performed to ensure the stability and continuity of the system.

[0075] Based on the above embodiments, the step of performing activation end conversion between the first AOM and the second AOM according to the train status information includes:

[0076] If communication between the first AOM and the TIAS is interrupted, but communication between the first AOM and the second AOM is normal, it is determined that the first AOM is switched from an active end to an inactive end, and the second AOM is switched from an inactive end to an active end.

[0077] Figure 3 The bold box indicates the active end, and the dashed line indicates a communication interruption. For example... Figure 3 As shown, after the first AOM is powered on and becomes the active end, if the communication between the first AOM and the TIAS subsystem is interrupted but the communication between the first and last AOMs is normal, the second AOM can learn from the communication information between the first and last AOMs sent by the first AOM that the current active end, the first AOM, is abnormal. Then, after the first AOM establishes a communication connection with the TIAS subsystem, it will actively upgrade to the active end. At the same time, when the first AOM can learn from the communication information between the first and last AOMs sent by the second AOM that the second AOM is in an active state, it can actively downgrade to an inactive end.

[0078] This embodiment can avoid the impact of a single point of failure on the operation of the entire system by means of the above methods, and at the same time can achieve higher fault tolerance and easy backup mechanism.

[0079] In some embodiments, the activation end conversion between the first AOM and the second AOM based on the train status information includes:

[0080] If the communication between the first AOM and the first ATP is interrupted, but the communication between the first AOM and the second AOM is normal, and the communication between the second AOM and the second ATP is normal, or if the communication between the first AOM and the first ATP is interrupted, but the communication between the first AOM and the second AOM is normal, and the communication between the second AOM and the second ATP is normal and then interrupted, but the ID of the second AOM is even, then it is determined that the first AOM is converted from the active end to the inactive end, and the second AOM is converted from the inactive end to the active end.

[0081] The process further includes, after the first AOM is converted from the active end to the inactive end, and the second AOM is converted from the inactive end to the active end:

[0082] If communication between the first AOM and the second AOM is normal, and communication between the first AOM and the first ATP has resumed, but communication between the second AOM and the second ATP is interrupted and has not been restored, then it is determined that the first AOM changes from an inactive end to an active end, and the second AOM changes from an active end to an inactive end; or...

[0083] If the communication between the first AOM and the second AOM is normal, but the communication between the second AOM and the TIAS is interrupted and not restored, it is determined that the first AOM is converted from an inactive end to an active end, and the second AOM is converted from an active end to an inactive end.

[0084] In this case, the even number of the ID of the second AOM indicates that it is a device deployed at the rear of the train.

[0085] Figure 4 The bold box indicates the active end, and the dashed line indicates a communication interruption. For example... Figure 4 As shown, after the first AOM powers on and becomes the active end, under normal head-to-tail communication conditions, the second AOM can learn from the head-to-tail AOM communication information sent by the first AOM that the communication between the first AOM and the first ATP is interrupted. However, if the communication between the second AOM and the second AOM is currently normal, then after the first AOM establishes a communication connection with the TIAS subsystem, it will actively upgrade to the active end. At the same time, after the first AOM learns from the head-to-tail AOM communication information sent by the second AOM that the communication between the second AOM and the second AOM is normal, it will actively downgrade to the inactive end.

[0086] In one example, the second AOM may communicate normally with the first AOM before sending the first and last AOM communication information. However, after sending the first and last AOM communication information, the communication between the second AOM and the first AOM may be interrupted. Since the first AOM will become inactive after receiving the first and last AOM communication information sent by the second AOM, in order to avoid the failure of the first and last dual centers being inactive, the second AOM deployed at the rear of the train will actively upgrade to an active end.

[0087] After the activation switch between the first AOM and the second AOM is interrupted due to the first ATP communication interruption, the communication status between the first ATP and the second ATP continues to be monitored. If the communication between the first ATP and the first AOM returns to normal, in order to avoid frequent switching affecting system stability, the second AOM continues to remain active, and the first AOM continues to remain inactive, until the activation switching condition is met.

[0088] If communication between the second ATP and the second AOM is interrupted, while communication between the first ATP and the first AOM remains interrupted, then the activation of either the first AOM or the second AOM has no impact on system stability. In order to avoid frequent switching affecting system stability, the second AOM continues to remain in an active state until communication between the first ATP and the first AOM is restored to normal, and communication between the second ATP and the second AOM remains interrupted. At this point, the first AOM actively becomes the active end, and the second AOM actively becomes the inactive end.

[0089] If communication between the second AOM and both the second ATP and TIAS systems is interrupted, while communication between the first ATP and the first AOM remains interrupted, the second AOM will remain active until a communication connection is established between the first AOM and the TIAS system. If communication between the first ATP and the first AOM, and between the second ATP and the second AOM, remains interrupted, the first AOM will become the active end, and the second AOM will become the inactive end.

[0090] This embodiment ensures that frequent switching of the activation end will not affect system stability when a fault occurs between AOM and ATP.

[0091] Based on the above embodiments, the step of performing activation end conversion between the first AOM and the second AOM according to the train status information includes:

[0092] In the event of a communication interruption between the first AOM and the second AOM, the second AOM is determined to be switched from an inactive end to an active end.

[0093] After the second AOM is converted from an inactive end to an active end, it also includes:

[0094] If communication between the first AOM and the second AOM returns to normal, and the first AOM is the active endpoint with an odd-numbered ID, then the first AOM is determined to be switched from an active endpoint to an inactive endpoint; or,

[0095] If communication between the first AOM and the second AOM is restored, communication between the first AOM and the first ATP is interrupted, communication between the second AOM and the second ATP is interrupted, and the first AOM is an active endpoint with an odd ID, then the first AOM is determined to be converted from an active endpoint to an inactive endpoint; or...

[0096] If communication between the first AOM and the second AOM is restored to normal, but communication between the first AOM and the first ATP is interrupted, but communication between the second AOM and the second ATP is normal, it is determined that the first AOM is switched from the active end to the inactive end.

[0097] Figure 5 The bold box indicates the active end, and the dashed line indicates a communication interruption. For example... Figure 5 As shown, after the first AOM is powered on and becomes the active end, if the communication between the first and last AOMs is interrupted, the first AOM and the second AOM cannot know the current communication status between the other party and each subsystem. In order to avoid the failure of the first and last dual centers being inactive, the second AOM actively upgrades to become the active end, while the first AOM continues to maintain the active state.

[0098] After the communication between the first and last trains is restored to normal, in order to avoid data conflicts caused by dual activation and affecting the normal operation of the system, the first AOM deployed at the head of the train will actively deactivate itself after learning that the second AOM is the active end. In the case that the communication between the first AOM and the first ATP, and between the second AOM and the second ATP are normal, or the communication between the first AOM and the first ATP, and between the second AOM and the second ATP are interrupted, in order to avoid the second AOM from frequently switching between active and inactive in a short period of time and causing its abnormal operation, the second AOM will remain active.

[0099] After the communication between the first and last terminals is restored to normal, if the communication between the first AOM and the first ATP is interrupted, while the communication between the second AOM and the second ATP is normal, then in order to ensure that the system can operate normally, the first AOM will actively become an inactive terminal, while the second AOM will remain active.

[0100] This embodiment ensures system stability even when failures occur at the beginning or end.

[0101] Based on the above embodiments, the step of performing activation end conversion between the first AOM and the second AOM according to the train status information includes:

[0102] If the communication between the first AOM and the TIAS is interrupted, the communication between the first AOM and the first ATP is interrupted, and the communication between the first AOM and the second AOM is normal, it is determined that the first AOM is converted from the active end to the inactive end, and the second AOM is converted from the inactive end to the active end.

[0103] The process further includes, after the first AOM is converted from the active end to the inactive end, and the second AOM is converted from the inactive end to the active end:

[0104] If communication between the first AOM and the first ATP is restored to normal, or if communication between the second AOM and the second ATP is interrupted, it is determined that no activation switch will be performed between the first AOM and the second AOM.

[0105] Figure 6 The bold box indicates the active end, and the dashed line indicates a communication interruption. For example... Figure 6 As shown, after the first AOM is powered on and becomes the active end, if the communication between the first AOM and the TIAS subsystem and the first ATP is interrupted but the communication between the first and last AOMs is normal, the second AOM can learn from the communication information between the first and last AOMs sent by the first AOM that the current active end, the first AOM, is abnormal. Then, after the first AOM establishes a communication connection with the TIAS subsystem, it will actively upgrade to the active end. At the same time, when the first AOM can learn from the communication information between the first and last AOMs sent by the second AOM that the second AOM is in an active state, it can actively downgrade to the inactive end.

[0106] After the activation switch between the first AOM and the second AOM was interrupted due to the communication interruption between the first AOM and the first ATP and TIAS subsystems, monitoring continued. In subsequent monitoring, if the communication between the second AOM and the TIAS subsystem was normal, regardless of whether the communication between the first ATP and the first AOM was restored to normal or the communication between the second ATP and the second AOM was interrupted, in order to avoid frequent switching affecting system stability, the second AOM continued to remain in the active state and the first AOM continued to remain in the inactive state.

[0107] Based on the above embodiments, the step of performing activation end conversion between the first AOM and the second AOM according to the train status information includes:

[0108] If communication between the first AOM and the TIAS is interrupted, and communication between the first AOM and the second AOM is also interrupted, it is determined that the second AOM is converted from an inactive end to an active end.

[0109] After the second AOM is converted from an inactive end to an active end, it also includes:

[0110] If communication between the first AOM and the second AOM is restored, but communication between the first AOM and the TIAS is not restored, then the first AOM is determined to be switched from an active to an inactive state; or...

[0111] If communication between the first AOM and the second AOM returns to normal, communication between the first AOM and the TIAS returns to normal, and the first AOM is an active endpoint with an odd-numbered ID, then the first AOM is determined to be switched from an active endpoint to an inactive endpoint; or...

[0112] If communication between the first AOM and the TIAS is restored to normal, but communication between the first AOM and the second AOM is not restored, it is determined that no activation switch will be performed between the first AOM and the second AOM.

[0113] Figure 7 The bold box indicates the active end, and the dashed line indicates a communication interruption. For example... Figure 7 As shown, after the first AOM is powered on and becomes the active end, if the communication between the first AOM and the TIAS subsystem is interrupted, but the communication between the first and last AOMs is also interrupted, then the second AOM and the second AOM cannot know the current communication status between the other party and each subsystem. In order to avoid the failure of the first and last dual centers being inactive, the second AOM actively upgrades to become the active end, while the first AOM continues to maintain the active state.

[0114] After the communication between the head and tail ends is restored, if the communication between the first AOM deployed at the head of the train and TIAS is not restored, the first AOM will be deactivated, while the second AOM will remain active.

[0115] With the communication between the head and tail ends restored to normal, and the communication between the first AOM and TIAS restored to normal, in order to avoid data conflicts caused by dual activation ends and affect the normal operation of the system, the first AOM deployed at the head of the train, after learning that the second AOM is the active end, actively degrades to the inactive end after the communication between the first AOM and the first ATP, and between the second AOM and the second ATP are normal, in order to avoid the second AOM frequently switching between active and inactive in a short period of time and causing its abnormal operation. The second AOM continues to remain active.

[0116] If communication between the first AOM and TIAS is restored to normal, but communication between the first and last AOMs is interrupted, the second AOM and the first AOM will remain active in order to avoid a failure where both the first and last AOMs are inactive.

[0117] Based on the above embodiments, the step of performing activation end conversion between the first AOM and the second AOM according to the train status information includes:

[0118] In the event that communication between the first AOM and the second AOM is interrupted, and communication between the first AOM and the first ATP is interrupted, it is determined that the second AOM is converted from an inactive end to an active end;

[0119] After the second AOM is converted from an inactive end to an active end, it also includes:

[0120] If communication between the first AOM and the second AOM is restored, but communication between the first AOM and the first ATP is not restored, then the first AOM is determined to be switched from an active to an inactive state; or...

[0121] If communication between the first AOM and the second AOM is restored, communication between the first AOM and the first ATP is restored, and the first AOM is an active endpoint with an odd ID, then the first AOM is determined to be converted from an active endpoint to a non-active endpoint; or,

[0122] If communication between the first AOM and the first ATP is restored, but communication between the first AOM and the second AOM is not restored, it is determined that no activation switch will be performed between the first AOM and the second AOM.

[0123] Figure 8 The bold box indicates the active end, and the dashed line indicates a communication interruption. For example... Figure 8 As shown, after the first AOM is powered on and becomes the active end, if the communication between the first AOM and the first ATP is interrupted, but the communication between the first and last AOMs is also interrupted, then the second AOM and the second AOM cannot know the current communication status between each other and each subsystem. In order to avoid the failure of the first and last dual centers being inactive, the second AOM actively upgrades to the active end, while the first AOM continues to maintain the active state.

[0124] If communication between the first and last ends is restored to normal, but communication between the first AOM and the first ATP is interrupted and not restored, while communication between the second AOM and the second ATO is normal, it indicates that the equipment deployed on the tail end side can operate normally. In this case, the first AOM will be actively degraded to an inactive state, while the second AOM will remain active.

[0125] With the communication between the first and last trains restored to normal, and the communication between the first AOM and the first ATP also restored to normal, in order to avoid data conflicts caused by dual activation and affect the normal operation of the system, the first AOM deployed at the head of the train, after learning that the second AOM is the active end, actively degrades to the inactive end after the communication between the first AOM and the first ATP, and between the second AOM and the second ATP, and in order to avoid the second AOM frequently switching between active and inactive in a short period of time and causing its abnormal operation, while the second AOM remains active.

[0126] If communication between the first AOM and TIAS is restored to normal, but communication between the first and last AOMs is interrupted, the second AOM and the first AOM will remain active in order to avoid a failure where both the first and last AOMs are inactive.

[0127] This embodiment, through the above method, can promptly detect abnormal situations, thereby enabling a rapid response and activation switch to ensure the stability and continuity of the system.

[0128] The train control device provided by this invention is described below.
