[0002] The Railway Signal Safety Protocol (RSSP) is a secure communication protocol used in the interfaces of railway signal safety equipment. RSSP is mainly used to ensure the safety and reliability of railway signaling systems during communication and is suitable for communication between various railway signaling devices.

[0003] Protocol stack parameters are required for configuring RSSP and need to be pre-programmed into the train's main control system. Each train uses different communication equipment, resulting in unique protocol stack parameters for each train. Therefore, protocol stack parameters need to be written and configured individually for each train. This method is prone to errors in programming the protocol stack parameters, affecting normal train communication. Summary of the Invention

[0004] This invention provides a railway safety protocol configuration method, apparatus, equipment, medium, and product to solve the problem that programming errors can easily occur when configuring protocol stack parameters separately for different trains.

[0008] Configure a railway signal safety protocol array based on the aforementioned protocol stack parameters;

[0009] The railway signal safety protocol array is used to establish communication connections with communication equipment in the train operating section.

[0016] At least one processor; and

[0017] A memory communicatively connected to the at least one processor; wherein,

[0018] The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to execute the railway safety protocol configuration method according to any embodiment of the present invention.

[0019] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the railway safety protocol configuration method according to any embodiment of the present invention.

[0020] According to another aspect of the present invention, a computer program product is provided, including a computer program that, when executed by a processor, implements the railway safety protocol configuration method of any embodiment of the present disclosure.

[0021] The technical solution of this invention involves the onboard ATP (Automatic Train Protection) reading a pre-programmed protocol parameter file to obtain the protocol stack parameters of all communication devices in the train's operating section.

[0033] Example 1

[0034] Figure 1 This is a flowchart of a railway safety protocol configuration method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where a unified protocol stack parameter file is pre-programmed into all trains associated with a train operating section. This method can be executed by a railway safety protocol configuration device, which can be implemented in hardware and / or software. This railway safety protocol configuration device can be configured in various general-purpose computing devices, for example, in an Automatic Train Protection (ATP) system. Figure 1 As shown, the method includes:

[0035] S110. Read the protocol stack parameters of each communication device in the train operating section from the protocol stack parameter file; the protocol stack parameter files used by at least one train associated with the same train operating section are the same, and all contain the protocol stack parameters of all communication devices in the train operating section.

[0036] A train operating section is a specific area within a railway transportation network that a train traverses from its origin to its destination. A train operating section includes multiple communication devices, such as multiple ground control centers (GCCs) deployed at intervals along the section, onboard communication equipment on at least one train passing through the section, and other communication equipment within the section. Each train contains at least two communication devices, including onboard ATP (Automatic Train Protection) and onboard tail-end communication equipment.

[0037] The protocol stack parameter file is a parameter file used by the train's ATP (Automatic Train Protection) system when establishing communication with other communication devices within the train's operating section. The protocol stack parameter file needs to be pre-burned into the non-volatile memory associated with the train ATP for use when establishing communication connections with other communication devices.

[0038] In existing technologies, the protocol stack parameter file required for each train is written based on the other communication devices that the train needs to establish communication with, and contains the protocol stack parameters of the other communication devices that the train needs to establish communication connections with. Since the communication devices that each train needs to establish communication connections with are different, the protocol stack parameter file for each train is unique and needs to be written and burned separately.

[0039] For example, if Train 1's onboard ATP1 needs to establish communication with Train 2's onboard ATP2, onboard tail section, ground GCC1, and ground GCC2 within the same train operating section, then a protocol stack parameter file containing the protocol stack parameters of the aforementioned communication devices needs to be written and burned into the flash memory of onboard ATP1. Similarly, if Train 2's onboard ATP2 needs to establish communication with Train 1's onboard ATP1, onboard tail section, ground GCC1, and ground GCC3 within the same train operating section, then a protocol stack parameter file containing the protocol stack parameters of the aforementioned communication devices needs to be written and burned into the flash memory of onboard ATP1. Clearly, the protocol stack parameter files required for the onboard ATP of Train 1 and Train 2 are different.

[0040] When there are a large number of trains, the above method is complex and error-prone in both programming and burning, and errors can only be detected when the train establishes a communication connection, which seriously affects the normal communication of the train.

[0041] To reduce programming and flashing errors, in this embodiment of the invention, at least one train associated with the same train operating section flashes the same protocol stack parameter file, which contains the protocol stack parameters of all communication devices in the train operating section. When establishing a communication connection, the train can selectively use the protocol stack parameters contained in the protocol stack parameter file.

[0042] During the initialization of the onboard ATP, the protocol stack parameters of each communication device in the train's operating section are first read from the protocol stack parameter file. Specifically, the protocol stack parameters of each communication device can be read from the protocol stack parameter file based on its identification code. The protocol stack parameters of each communication device include its device layer parameters and the session layer parameters between the communication device and the current onboard ATP.

[0043] S120. Configure the railway signal safety protocol array based on the protocol stack parameters; the railway signal safety protocol array is used to establish communication connections with communication equipment in the train operating section.

[0044] In this embodiment of the invention, based on the parameter composition principles of Railway Signal Safety Protocol-1 (RSSP-1), the system further configures the railway signal safety protocol array associated with the current onboard ATP based on the read protocol stack parameters, providing the onboard ATP with the parameter basis for establishing a communication connection. When the onboard ATP needs to establish a communication connection with a target communication device, it needs to read the protocol stack parameters associated with the target communication device from the railway signal safety protocol array.

[0045] The railway signaling safety protocol array includes Safety Function Management Layer (SFM) data and Communication Function Management Layer (CFM) data. The SFM array is formed by the SFM data corresponding to each communication device, and the CFM array is formed by the CFM data corresponding to each communication device.

[0046] The technical solution of this invention involves the onboard ATP (Automatic Train Protection) reading a pre-programmed protocol parameter file to obtain the protocol stack parameters of all communication devices in the train's operating section. Based on these protocol stack parameters, a railway signal safety protocol array is configured to establish communication connections with other communication devices in the train's operating section. By pre-programming a unified protocol stack parameter file into each train associated with the train's operating section, the onboard ATP of each train can configure railway signal safety protocol data based on the protocol stack parameter file, providing parameter basis for establishing communication between the train and other communication devices. Compared to the method of programming different protocol stack parameter files for each train, this solution can reduce the error rate of programming protocol stack parameters.

[0047] Example 2

[0048] Figure 2a This is a flowchart of a railway safety protocol configuration method provided in Embodiment 2 of the present invention. This embodiment further refines the above embodiment, providing specific steps for configuring a railway signaling safety protocol array based on protocol stack parameters, and specific steps following the configuration of the railway signaling safety protocol array based on protocol stack parameters. Figure 2a As shown, the method includes:

[0049] S210. Read the protocol stack parameters of each communication device in the train operating section from the protocol stack parameter file; the protocol stack parameter files used by at least one train associated with the same train operating section are the same, and all contain the protocol stack parameters of all communication devices in the train operating section.

[0050] Optionally, the protocol stack parameter file includes a protocol stack data packet consisting of session layer parameters associated with each type of communication device in the current onboard ATP and the device layer parameters of each communication device in the current operating section.

[0051] When a train operating section contains a large number of communication devices, each device has corresponding device-level parameters and session-level parameters between that device and the current onboard ATP (Automatic Train Protection). This results in the protocol stack parameters of all communication devices occupying a significant amount of storage space.

[0052] To reduce the space occupied by the protocol stack parameter file, the protocol stack parameters need to be compressed for storage. In this optional embodiment, the compression principle is based on the classification of common and unique attributes in the protocol stack parameters. Specifically, communication devices belonging to the same device type have the same session layer parameters in their protocol stack parameters, while the device layer parameters of each communication device are different. Therefore, the parameters with the same characteristics can be compressed. That is, for multiple communication devices belonging to the same device type, the corresponding session layer parameters are stored only once. The final protocol stack data packet consists of the session layer parameters associated with each type of communication device in the current onboard ATP and the device layer parameters of each communication device in the current operating section. The protocol stack data packet is a part of the protocol stack parameter file.

[0053] Optionally, the protocol stack parameter file is a binary file consisting of a file header, file length, file version, protocol stack data packets, and file checksum.

[0054] In a specific example, the types of communication equipment in the train operating section are as follows: Figure 2b As shown, it includes onboard ATP at the train end, onboard train tail and other onboard equipment, as well as ground GCC and other ground equipment.

[0055] To ensure that all trains connected to the same operating section can have a unified protocol stack parameter file burned into it, the protocol stack parameters of all communication devices within the train operating section are centrally compiled into this protocol stack parameter file. Specifically, as follows... Figure 2c As shown, the train operating section includes onboard ATP1, onboard tail 1, ground GCC1, onboard ATP2, onboard tail 2, and ground GCC2. The protocol stack parameter file contains the session layer parameters and device layer parameters associated with the above communication devices.

[0056] To reduce the space occupied by the protocol stack parameter file, the protocol stack parameters need to be compressed for storage, specifically as follows: Figure 2dAs shown, the session layer parameters associated with communication devices of the same device type are stored only once. In other words, the session layer parameters stored on a per-communication-device basis are changed to stored on a per-device-type basis. The device layer parameters of each communication device are saved separately to form protocol stack data packets, saving a lot of storage space.

[0057] Furthermore, a binary file (bin file) consisting of a file header, file length, file version, protocol stack data packets, and file checksum is burned into the onboard ATP of each train in the train operating section.

[0058] Optionally, the protocol stack parameters of each communication device in the train operating section can be read from the protocol stack parameter file, including:

[0059] One communication device in the train operating section is extracted as the current communication device. Based on the identification code of the current communication device, the device layer parameters of the current communication device are extracted from the protocol stack parameter file, and the device type of the current communication device is read from the device layer parameters.

[0060] Based on the device type of the current communication device, determine the session layer parameters between the current vehicle-mounted ATP and the current communication device;

[0061] The device layer parameters of the current communication device, as well as the session layer parameters between the current onboard ATP and the current communication device, are stored in the current train's running memory as the protocol stack parameters of the current communication device. Then, the system returns to execute the operation of sequentially extracting one communication device from the train's operating section as the current communication device, until the protocol stack parameters of each communication device in the train's operating section are obtained.

[0062] In this optional embodiment, a specific scheme is provided for reading the protocol stack parameters of each communication device in the train operating section from the protocol stack parameter file: Since the protocol stack parameters in the protocol stack parameter file are compressed, during the onboard ATP initialization process, the compressed parameters need to be decompressed, and the protocol stack parameters of all communication devices need to be read again. First, one communication device in the train operating section is extracted as the current communication device. Based on the identification code of the current communication device, the device layer parameters of the current communication device are extracted from the protocol stack parameter file. Then, the device layer parameters are parsed to obtain the device type of the current communication device. Based on the device type of the current communication device, the session layer parameters between the current onboard ATP and the current communication device are determined. Finally, the device layer parameters of the current communication device and the session layer parameters between the current onboard ATP and the current communication device are stored as the protocol stack parameters of the current communication device in the running memory of the current train, and the process of extracting one communication device in the train operating section as the current communication device is returned to be executed until the protocol stack parameters of each communication device in the train operating section are obtained.

[0063] S220. Based on the session layer parameters and device layer parameters of each communication device in the protocol stack parameters, construct the security function management layer array and the communication function management layer array.

[0064] In this embodiment of the invention, based on the RSSP-1 parameter composition principle and the read protocol stack parameters, the railway signal safety protocol array associated with the current onboard ATP is configured to provide the onboard ATP with parameter basis for establishing a communication connection.

[0065] First, based on the session layer parameters and device layer parameters of each communication device in the protocol stack parameters, a security function management layer array and a communication function management layer array are constructed. These arrays pre-configure session layer parameter items and device layer parameter items associated with the security function management layer array, as well as those associated with the communication function management layer array.

[0066] Specifically, the session layer parameter items and device layer parameter items associated with the security function management layer array are extracted from the protocol stack parameters to form the security function management layer array. Then, the session layer parameter items and device layer parameter items associated with the communication function management layer array are extracted from the protocol stack parameters to form the communication function management layer array.

[0067] S230. The safety function management layer array and the communication function management layer array are combined into a railway signal safety protocol array.

[0068] In this embodiment of the invention, after extracting the safety function management layer array and the communication function management layer array, the safety function management layer array and the communication function management layer array are used together as the railway signal safety protocol array to provide parameter basis for subsequent communication between the on-board ATP and other communication devices.

[0069] S240. In response to receiving a communication connection task, read the identity identifier of the terminal to be communicated in the communication connection task.

[0070] In this embodiment of the invention, after receiving a communication connection task, the vehicle-mounted ATP first parses the communication connection task and reads the identity identifier of the terminal to be communicated contained therein, so as to obtain the protocol stack parameters associated with the terminal to be communicated based on the identity identifier.

[0071] S250. Based on the identity identifier, read the protocol stack parameters associated with the terminal to be communicated from the railway signal security protocol array.

[0072] In this embodiment of the invention, protocol stack parameters associated with the terminal to be communicated are read from the railway signaling safety protocol array based on the identity identifier of the terminal to be communicated. Specifically, based on the identity identifier, a portion of session layer parameters and device layer parameters associated with the terminal to be communicated are read from the security function management layer data of the railway signaling safety protocol array. Simultaneously, another portion of session layer parameters and device layer parameters associated with the terminal to be communicated are read from the communication function management layer data of the railway signaling safety protocol array. Finally, the resulting parameter set is used as the protocol stack parameters associated with the terminal to be communicated.

[0073] S260. Based on the protocol stack parameters associated with the terminal to be communicated, establish a communication connection with the terminal to be communicated.

[0074] In this embodiment of the invention, after obtaining the protocol stack parameters associated with the terminal to be communicated, the data to be sent is transmitted based on the obtained protocol stack parameters according to the railway signaling safety protocol. Specifically, a railway signaling safety communication protocol stack is added between the application layer and the network layer based on the protocol stack parameters to ensure communication stability and security.

[0075] The technical solution of this invention stores the protocol stack parameters of all communication devices in the train operating section by device type, which compresses the size of the protocol stack parameter file and saves the flash memory space of the onboard ATP. Furthermore, based on the protocol stack parameters, a railway signal safety communication protocol stack is added between the application layer and the network layer to ensure communication stability and security.

[0080] The railway safety protocol configuration module 320 is used to configure the railway signal safety protocol array based on the protocol stack parameters;

[0081] The railway signal safety protocol array is used to establish communication connections with communication equipment in the train operating section.

[0082] The technical solution of this invention involves the onboard ATP (Automatic Train Protection) reading a pre-programmed protocol parameter file to obtain the protocol stack parameters of all communication devices in the train's operating section. Based on these protocol stack parameters, a railway signal safety protocol array is configured to establish communication connections with other communication devices in the train's operating section. By pre-programming a unified protocol stack parameter file into each train associated with the train's operating section, the onboard ATP of each train can configure railway signal safety protocol data based on the protocol stack parameter file, providing parameter basis for establishing communication between the train and other communication devices. Compared to the method of programming different protocol stack parameter files for each train, this solution can reduce the error rate of programming protocol stack parameters.

[0086] Based on the device type of the current communication device, determine the session layer parameters between the current vehicle-mounted ATP and the current communication device;

[0087] The device layer parameters of the current communication device, as well as the session layer parameters between the current onboard ATP and the current communication device, are stored in the current train's running memory as the protocol stack parameters of the current communication device. Then, the system returns to execute the operation of sequentially extracting one communication device from the train's operating section as the current communication device, until the protocol stack parameters of each communication device in the train's operating section are obtained.
