Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and in particular to a redundant current-controlled vehicle method, apparatus, and electronic equipment. Background Technology

[0002] The current loop system is a crucial medium for transmitting traction and braking positions between the Automatic Train Operation (ATO) system and the train. A malfunction in this system can lead to problems such as loss of traction and braking force. In minor cases, it can cause the train to slow down, resulting in a decrease in on-time performance. In severe cases, it can lead to speeding and safety hazards due to the failure to reduce speed in time.

[0003] In existing technologies, the ATO (Autonomous Vehicle-to-Everything) architecture of autonomous driving systems uses a current loop control architecture, and generally only uses an independent current loop system. It fails to incorporate a system architecture involving safety systems to cope with sudden current loop anomalies. Therefore, the current loop control architecture cannot take emergency measures when a current loop anomaly is detected, and is limited to the logic of manual handling. Once a fault occurs, manual intervention is required, resulting in a waste of human resources and posing a potential safety hazard. Summary of the Invention

[0004] This invention provides a redundant current loop control vehicle method, device, and electronic equipment to solve the technical problem that the current loop control vehicle architecture in the prior art cannot take emergency measures when an abnormality in the current loop is detected, and is limited to the logic of manual handling. Once a fault occurs, manual intervention is required, which wastes human resources and also poses a hidden danger to safe driving.

[0005] This invention provides a redundant current-controlled vehicle method, comprising the following steps:

[0006] When the train needs to perform extreme position control, the extreme position information output by the automatic train operation system is sent to the current loop through the main channel, and the current information of the current loop is collected back through the automatic train operation system. The current loop is used to perform extreme position control of the train.

[0007] When the current information indicates an abnormality in the current loop, the extreme position information is forwarded to the train automatic protection system through the backup channel;

[0008] The extreme position information is transmitted to the train through the automatic train protection system, so that the train can perform extreme position control based on the extreme position information.

[0009] In some embodiments, the automatic train protection system includes a real-time train data protocol board, and transmitting the extreme position information to the train through the automatic train protection system includes:

[0010] The extreme position information is transmitted to the train using the train real-time data protocol board.

[0011] In some embodiments, after retrieving the current information of the current loop through the automatic train operation system, the method further includes:

[0012] When the current information characterizes the output extreme position information correctly, the current loop is determined to be normal.

[0013] When the current information characterizes the output extreme position information incorrectly, the current loop is determined to be abnormal.

[0014] In some embodiments, when it is determined that the current loop is normal, the method further includes:

[0015] The train collects current change information and performs extreme position control based on the current change information. The current change information is generated after the current loop receives the extreme position information sent by the main channel.

[0016] In some embodiments, when it is determined that the current loop is normal, the method further includes:

[0017] The extreme position information output by the automatic train operation system is sent to the automatic train protection system via the backup channel, and the channel flag is set to use the main channel for extreme position train control.

[0018] In some embodiments, when determining that the current loop is abnormal, the method further includes:

[0019] The system sends a current loop anomaly information to the automatic train protection system to open the backup channel and set the channel flag to use the backup channel for extreme position control.

[0020] The present invention also provides a redundant current-controlled vehicle device, comprising the following modules:

[0021] The output module is used to send the extreme position information output by the automatic train operation system to the current loop through the main channel when the train needs to perform extreme position control, and to collect the current information of the current loop through the automatic train operation system. The current loop is used to perform extreme position control of the train.

[0022] The transmitting module is used to forward the extreme position information to the train automatic protection system through a backup channel when the current information indicates an abnormality in the current loop.

[0023] The train control module is used to transmit the extreme position information to the train through the automatic train protection system, so that the train can perform extreme position control based on the extreme position information.

[0024] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the redundant current-controlled vehicle method as described above.

[0025] The present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the redundant current-controlled vehicle method as described above.

[0026] The present invention also provides a computer program product, including a computer program that, when executed by a processor, implements the redundant current environmental control vehicle method as described above.

[0027] The redundant current loop control method, apparatus, and electronic equipment provided by this invention employ a redundant channel mode of main and backup channels to transmit extreme position information to the train for control when extreme position control is required. If a current loop anomaly prevents the main channel from transmitting extreme position information for control, the backup channel transmits the information to the train for control. Therefore, when a current loop anomaly is detected, timely measures can be taken to complete the control without manual intervention, saving manpower and increasing train operation safety.

[0033] 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.

[0034] The current-controlled vehicle method provided by this invention can be applied to various unmanned rail transit systems (or back-end management servers) to control the operation of trains and ensure the safety of train operation.

[0035] The following is combined Figure 1 The redundant current-controlled vehicle method of the present invention is described below. Figure 1 This is a flowchart illustrating the redundant current-controlled vehicle method provided by the present invention, as shown below. Figure 1 As shown, the method includes the following steps.

[0036] In step 101, when the train needs to perform extreme position control, the extreme position information output by the automatic train operation system is sent to the current loop through the main channel, and the current information of the current loop is retrieved through the automatic train operation system.

[0037] Rail transit trains are generally driven automatically by ATO (Automatic Train Control). The current loop is an important medium for transmitting traction and braking positions between the ATO and the train. The current loop architecture used by ATO generally only uses an independent current loop system. By controlling the current magnitude through the current loop, the train can be braked or controlled.

[0038] See Figure 2 , Figure 2 This is a schematic diagram illustrating the operating principle of the redundant current-controlled vehicle method provided by this invention, as shown below. Figure 2 As shown, when the train needs to perform extreme position control, the extreme position information output by the ATO is sent to the current loop via the main channel, and then the current information of the current loop is retrieved back through the ATO. The current loop is used for extreme position control of the train.

[0039] Here, when the train encounters an emergency requiring extreme position control, the ATO outputs the corresponding extreme position current as extreme position information and sends it to the current loop via the main channel. Upon receiving the extreme position current, the current loop sends the extreme position information back to the train, enabling extreme position control. To ensure the accuracy of the output extreme position information (i.e., the extreme position current), the ATO samples the current information from the current loop for verification, determining if the current loop is malfunctioning and thus whether train control is safe. The main channel and backup channel in this invention can be either information transmission channels or current transmission channels, used to transmit extreme position information or current information, etc.

[0040] In some embodiments, after the ATO (Automatic Train Operation) collects the current information from the current loop, it determines whether the output extreme position information is correct based on the current information. When the current information indicates that the extreme position information output by the Automatic Train Operation system is correct, the current loop is determined to be normal, indicating that the main channel can perform extreme position control normally. When the current information indicates that the output extreme position information is incorrect, the current loop is determined to be abnormal, possibly due to a malfunction in the current loop system, indicating that the main channel cannot perform extreme position control normally.

[0041] In some embodiments, such as Figure 2 As shown, when the current loop is confirmed to be normal, it means that the channel can perform extreme position control normally. After the current loop receives the extreme position information sent by the main channel, it will generate current change information. At this time, vehicle acquisition is performed, that is, the current change information of the current loop is collected through the train, and then the speed of the train is controlled according to the current change information to perform extreme position control.

[0042] See also Figure 1 In step 102, when the current information indicates an abnormality in the current loop, the extreme position information is forwarded to the train automatic protection system through the backup channel.

[0043] In this embodiment of the invention, when the current information indicates an abnormality in the current loop, the main channel cannot perform extreme position control normally. At this time, the extreme position information can be forwarded to the Automatic Train Protection (ATP) system through the backup channel using the ATO.

[0044] like Figure 2As shown, during train operation, there is real-time internal communication between the ATO and ATP, allowing them to exchange data and share information. The ATP is a system designed to ensure train safety. When a current loop anomaly occurs, it indicates a safety issue with the train that is uncontrollable. The ATP immediately activates, and the ATO sends a current loop anomaly message to the ATP, indicating a primary channel malfunction and activating the backup channel. The backup channel flag is set to 0, signifying that the backup channel is being used for train control. Furthermore, when sending the current loop anomaly message, the ATO also forwards extreme position information to the ATP through the backup channel for extreme position train control.

[0045] See also Figure 1 In step 103, the extreme position information is transmitted to the train through the automatic train protection system so that the train can perform extreme position control based on the extreme position information.

[0046] In some embodiments, after the ATP receives the current loop anomaly information sent by the ATO and the extreme position information forwarded through the backup channel, it then transmits the extreme position information to the train through the ATP, so that the train can perform extreme position control based on the extreme position information. Here, as... Figure 2 As shown, the ATP has a train real-time data protocol (TRDP) board. When transmitting extreme position information to the train, the ATP uses the TRDP board to transmit the extreme position information to the train. The train collects the vehicle data, that is, it collects the extreme position information and controls the speed of the vehicle according to the extreme position information, so as to perform extreme position control and make the control smoother.

[0047] Therefore, through the redundant design of the main and backup channels, when the main channel fails and extreme position control is not performed, the backup channel can immediately take over the work, thereby reducing the impact of current loop anomalies on train control and improving reliability. Furthermore, in the event of a current loop anomaly, the backup channel maintains the stability of the current loop control, achieving smooth train control, preventing the train system from losing control, and improving the stability of the train system.

[0048] In some embodiments, the backup channel can be hot standby. Specifically, even when the main channel can perform extreme position control normally (current loop is normal), the ATO will send extreme position information to the ATP through the backup channel. That is, the extreme position information output by the ATO is sent to the ATP through the backup channel, and the channel flag is set to 1, indicating that the main channel is used for extreme position control at this time.

[0049] In this embodiment of the invention, when the train needs to perform extreme position control, a redundant channel mode of main channel and backup channel is adopted to transmit extreme position information to the train for control. When the current loop is normal, the extreme position information is transmitted through the main channel to complete the train's extreme position control normally. However, when the current loop is abnormal and the main channel cannot transmit extreme position information, the extreme position information is transmitted to the train through the backup channel for control. By designing redundant channels, on the one hand, it allows for maintenance and upgrades of the current loop device or components without affecting the operation of the train system, ensuring maintainability. On the other hand, when an abnormality in the current loop is detected, backup measures can be taken in a timely manner to complete the train control without manual intervention, saving manpower and increasing the safety of train operation.

[0050] The redundant current-controlled vehicle device provided by the present invention will be described below. The redundant current-controlled vehicle device described below can be referred to in correspondence with the redundant current-controlled vehicle method described above.

Figure 3 As shown, the redundant current loop train control device includes an output module 301, a transmitting module 302, and a control module 303. The output module 301 is used to send the extreme position information output by the automatic train operation system to the current loop via the main channel when the train needs to perform extreme position control, and to collect the current information of the current loop through the automatic train operation system. The current loop is used for extreme position control of the train. The transmitting module 302 is used to forward the extreme position information to the automatic train protection system via a backup channel when the current information indicates an anomaly in the current loop. The control module 303 is used to transmit the extreme position information to the train through the automatic train protection system, so that the train can perform extreme position control based on the extreme position information.
