[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The current ring control vehicle method provided by the present invention can be applied to various unmanned driving systems (or background management servers) of rail transportation to control the operation of trains and ensure the safety of train operation.

[0023] Combine the following Figure 1 Describe the redundant current loop control vehicle method of the present invention, Figure 1 FIG. 1 is a flow chart of a redundant current loop control vehicle method provided by the present invention, such as Figure 1 As shown, the method includes the following steps.

[0024] In step 101, when the train needs to perform extreme position control, the extreme position information output by the train automatic operation system is sent to the current loop via the main channel, and the current information of the current loop is retrieved via the train automatic operation system.

[0025] Rail transit trains are generally driven automatically by ATO, and the current loop is an important medium for connecting ATO and trains to transmit traction and braking pole positions. In addition, the current loop architecture used by ATO automatic control trains generally only uses an independent current loop system. The current size is controlled by the current loop, which can brake or control the train.

[0026] See also Figure 2 , Figure 2 FIG. 1 is an operation principle diagram of the redundant current loop control vehicle method provided by the present invention, such as Figure 2 As shown, when the train needs to be controlled at the extreme position, the extreme position information output by the ATO is sent to the current loop using the main channel, and then the current information of the current loop is collected back through the ATO. The current loop is used to control the train at the extreme position.

[0027] Here, when the train encounters an emergency and needs to perform extreme position control, the ATO will output the corresponding extreme position current as the extreme position information, and send it to the current loop through the main channel. When the current loop receives the extreme position current, it will send the extreme position information to the train, and the train can be controlled at the extreme position. In order to ensure that the output extreme position information (that is, the extreme position current) is correct, the ATO will collect the current information of the current loop for verification to determine whether the current loop is abnormal, and then determine whether the train can be safely controlled. The main channel and the backup channel in the present invention can be an information transmission channel or a current transmission channel for transmitting data such as extreme position information or current information.

[0028] In some embodiments, after the ATO retrieves the current information of the current loop, it will be determined whether the output polarity information determined based on the current information is correct. When the current information indicates that the polarity information output by the train automatic operation system is correct, it is determined that the current loop is normal, indicating that the main channel can normally perform polarity control of the train at this time. When the current information indicates that the output polarity information is wrong, it is determined that the current loop is abnormal, which may be a fault in the current loop system device, indicating that the main channel cannot normally perform polarity control of the train at this time.

[0029] In some embodiments, Figure 2 As shown, when it is determined that the current loop is normal, it means that the channel can perform polar position control normally, and after the current loop receives the polar position information sent by the main channel, it will generate current change information. At this time, vehicle collection 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 polar position control.

[0030] Continue to see Figure 1 In step 102, when the current information indicates that the current loop is abnormal, the polarity information is forwarded to the automatic train protection system through the backup channel.

[0031] In an embodiment of the present invention, when the current information indicates that the current loop is abnormal, the main channel cannot normally perform extreme position control of the train. At this time, ATO can be used to forward the extreme position information to the Automatic Train Protection (ATP) system through the backup channel.

[0032] like Figure 2 As shown in the figure, when the train is running, there is real-time internal communication between ATO and ATP, and data can be transmitted to each other for information sharing. ATP is a system to ensure the safety of train operation. When the current loop is abnormal, it means that the train has a driving safety problem that cannot be controlled. At this time, ATP starts immediately. ATO will send current loop abnormality information to ATP, prompting the main channel abnormality to open the backup channel, and set the channel flag bit to 0, indicating that the backup channel is used to control the train at this time. And when sending the current loop abnormality information, ATO will also forward the extreme position information to ATP through the backup channel for extreme position control.

[0033] Continue to see 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 according to the extreme position information.

[0034] In some embodiments, after ATP receives the current loop abnormality information sent by ATO and the polarity information forwarded through the backup channel, ATP transmits the polarity information to the train, so that the train can perform polarity control according to the polarity information. Figure 2As shown, a train real-time data protocol (TRDP) board is provided in ATP. When transmitting the extreme position information to the train, ATP transmits the extreme position information to the train through the TRDP board using the train real-time data protocol (i.e. TRDP). The train collects vehicle information, that is, the train collects the extreme position information, and controls the speed of the vehicle according to the extreme position information, and performs extreme position control, making the vehicle control smoother.

[0035] Therefore, through the redundant channel design of the main channel and the backup channel, when the main channel fails and the train is not under control, the backup channel can immediately take over the work, thereby reducing the impact of abnormal current loop failures on train control and improving reliability. In addition, when the current loop is abnormal, the stability of the current loop control is maintained through the backup channel, and the train is controlled smoothly, preventing the train system from getting out of control, and improving the stability of the train system.

[0036] In some embodiments, the standby channel can be in hot standby mode. Specifically, even when the main channel can normally perform extreme position control (the current loop is normal), the ATO will send extreme position information to the ATP through the standby channel, that is, the extreme position information output by the ATO is sent to the ATP using the standby channel, and the channel flag is set to 1, indicating that the main channel is used for extreme position control at this time.

[0037] In an embodiment of the present invention, when a train needs to perform extreme position control, a redundant channel mode of a main channel and a backup channel is used to convey extreme position information to the train for train control. When the current loop is normal, the extreme position information is conveyed through the main channel to complete the extreme position control of the train. When the current loop is abnormal and the main channel cannot convey the extreme position information, the backup channel is used to convey the extreme position information to the train for train control. By designing redundant channels, on the one hand, it allows the devices or components of the current loop to be maintained and upgraded without affecting the operation of the train system, thereby ensuring maintainability. On the other hand, when an abnormality in the current loop is detected, backup measures can be taken in time to complete the train control without the need for manual intervention, which saves human resources and increases the safety of train operation.

The output module 301 is used to send the polarity information output by the train automatic operation system to the current loop using the main channel when the train needs to perform polarity control, and retrieve the current information of the current loop through the train automatic operation system, wherein the current loop is used to perform polarity control on the train; the sending module 302 is used to forward the polarity information to the train automatic protection system through the backup channel when the current information indicates that the current loop is abnormal; the vehicle control module 303 is used to transmit the polarity information to the train through the train automatic protection system, so that the train performs polarity control according to the polarity information.
