DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them.

In addition, the features described with reference to certain examples may be combined in other examples.

[0022] In order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and order of execution.

[0023] The embodiments of the present application describe some exemplary embodiments for the purpose of explanation. It should be understood that the present application can be implemented in other ways that are not specifically shown in the drawings.

[0024] like Figure 1 As shown, the embodiment of the present application provides a method for controlling the upgrading of trains under enhanced interlocking operation levels, and the method for controlling the upgrading of trains under enhanced interlocking operation levels can be applied to a device for controlling the upgrading of trains under enhanced interlocking operation levels. The method for controlling the upgrading of trains under enhanced interlocking operation levels may include S101-S102: S101: At the enhanced interlocking operation level, the train upgrade control device sends message information to the computer interlocking within the authorized application distance.

[0025] Among them, the above message information includes train location information.

[0026] Optionally, in the event of a zone controller failure, the message information is sent to the computer interlocking within the authorization application distance.

[0027] Specifically, for the enhanced interlocking mode (Block Mode, BM) level without active balises and LEUs, in order to complete the train upgrade control at the enhanced interlocking operation level, enhanced interlocking control application information and enhanced interlocking status information can be added to the interactive information between VOBC and CI, wherein the enhanced interlocking control application information is the link establishment application information actively sent by VOBC to the CI corresponding to the area where the train is located, and the enhanced interlocking status information is the virtual master balise message information of the train automatic protection system (Automatic Train Protection, ATP) replied by CI according to the display of the signal. In other words, in the event of a regional control failure, the train needs to switch from the RM level to the BM level. In the case of no active balises and LEUs, the VOBC on the train can first send an enhanced interlocking control application information to CI, and the enhanced interlocking control application information includes the above message information, so that CI can determine the current position of the train.

[0028] S102: If the automatic train protection system detects a target transponder with an upgrade attribute, and the signal state information in the message information returned by the computer interlocking is a permission signal, the train upgrade control device at the enhanced interlocking operation level enters the enhanced interlocking mode BM upgrade process.

[0029] The target transponder is located at a preset position in front of the signal, and the preset position is calculated based on the train-ground communication delay information and the train speed.

[0030] Specifically, Figure 2As shown, after CI receives the above message information, it can detect the status information of the signal A0 ahead. The signal includes an allow signal and a prohibit signal. The allow signal means that the train can pass, and the prohibit signal means that the train cannot pass. After that, CI can periodically generate enhanced interlocking status information according to the status information of signal A0, and send the enhanced interlocking status information to VOBC. Since there is a certain delay in sending point messages from CI to VOBC, even if the signal status information received at this time is an allow signal, the signal status may change when the train passes. In order to reduce the risk of vehicle-ground communication delay, a target transponder B1 can be set at a preset position in front of the signal A0. The target transponder B1 is an ordinary transponder with a BM upgrade attribute added. If the on-board ATP runs through and detects the target transponder B1, the received new enhanced interlocking control status information is judged within n cycles (n is a configuration value) after receiving the target transponder B1. If the first frame information of the enhanced interlocking control status information is an allow signal, the BM upgrade process is entered if other upgrade ITC conditions are met.

[0031] Optionally, if the automatic train protection system detects the target transponder and the signal status information returned by the computer interlocking is a prohibition signal, the BM upgrade process will not be entered.

[0032] Optionally, if the automatic train protection system does not detect the target transponder, the BM upgrade process is not entered.

[0033] That is to say, the BM upgrade process can only be entered when the two conditions of detecting the target transponder and receiving the permission signal are met.

[0034] It should be noted that the target balise is a balise deployed beside the track with the BM upgrade attribute added.

[0035] In an embodiment of the present application, a target transponder with upgrade attributes can be used as an upgrade trigger condition. Since the target transponder is located at a preset position in front of the signal, and the preset position is calculated based on the vehicle-ground communication delay information and the train speed, the delay effect of the computer interlocking sending BM messages to the on-board equipment controller through the vehicle-ground wireless system can be avoided, thereby reducing the system safety risks introduced by the vehicle-ground wireless communication during the train BM upgrade process.

[0036] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the method. In order to realize the above functions, it includes hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of each example described in the embodiment disclosed herein, the embodiment of the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present application.

[0037] The method for controlling train upgrades at an enhanced interlocking operation level provided in the embodiment of the present application can be executed by a train upgrade control device at an enhanced interlocking operation level, or a control module for controlling train upgrades at an enhanced interlocking operation level in the train upgrade control device at an enhanced interlocking operation level. In the embodiment of the present application, the method for controlling train upgrades at an enhanced interlocking operation level performed by a train upgrade control device at an enhanced interlocking operation level is taken as an example to illustrate the device for controlling train upgrades at an enhanced interlocking operation level provided in the embodiment of the present application.

[0038] It should be noted that the device in the embodiment of the present application includes a virtual device and a physical device. The virtual device can be a train upgrade control device at an enhanced interlocking operation level, and the physical device can include an electronic device, a computer storage medium, and a computer program product.

[0039] It should be noted that the embodiment of the present application can divide the functional modules of the train upgrade control device for the enhanced interlocking operation level according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of software functional modules. Optionally, the division of modules in the embodiment of the present application is schematic and is only a logical functional division. There may be other division methods in actual implementation.

[0040] like Figure 3As shown, an embodiment of the present application provides a train upgrade control device 300 under enhanced interlocking operation level. The train upgrade control device 300 under enhanced interlocking operation level includes: a communication module 301 and a processing module 302; the communication module 301 is used to send message information to the computer interlocking within the authorized application distance, and the message information includes train position information; the processing module 302 is used to enter the enhanced interlocking mode BM upgrade process if the train automatic protection system detects a target transponder with an upgrade attribute, and the signal machine status information in the message information returned by the computer interlocking is a permission signal; wherein, the target transponder is located at a preset position in front of the signal machine, and the preset position is calculated according to the train-ground communication delay information and the train speed.

[0041] Optionally, the processing module 302 is further configured not to enter the BM upgrade process if the automatic train protection system detects the target transponder and the signal state information in the message information returned by the computer interlocking is a prohibition signal.

[0042] Optionally, the processing module 302 is further configured not to enter the BM upgrade process if the automatic train protection system fails to detect the target transponder.

[0043] Optionally, the communication module 301 is specifically used to send the message information to the computer interlocking within the authorization application distance when a regional control failure occurs.

[0044] In an embodiment of the present application, a target transponder with upgrade properties can be used as an upgrade trigger condition. Since the target transponder is located at a preset position in front of the signal, the preset position is calculated based on the vehicle-to-ground communication delay information and the train speed. Therefore, the delay effect of sending point messages to the on-board equipment controller through computer interlocking can be avoided, thereby reducing the risk introduced by vehicle-to-ground communication without increasing the hardware investment cost.

[0046] In addition, the logic instructions in the above-mentioned memory 430 can be implemented in the form of a software functional unit and can be stored in a computer-readable storage medium when it is sold or used as an independent product. Based on this understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art or the part of the technical solution, can be embodied in the form of a software product, and the computer software product is stored in a storage medium, including a number of instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to perform all or part of the steps of the method described in each embodiment of the present invention.
