[0002] Railway Signal Safety Protocol (RSSP) is a safety communication protocol applied to the interface of railway signal safety equipment. RSSP is mainly used to ensure the safety and reliability of railway signal systems during communication and is applicable to communication between various railway signal equipment.

[0003] The protocol stack parameters are the parameters needed to configure RSSP. The protocol stack parameters need to be burned into the train master control system in advance. Each train needs to establish communication with different communication devices, which makes the protocol stack parameters of each train unique. Therefore, the protocol stack parameters need to be written and configured separately for each train. This method is prone to protocol stack parameter burning errors, affecting the normal communication of the train. Summary of the invention

[0004] The present invention provides a railway safety protocol configuration method, device, equipment, medium and product to solve the problem that burning errors are prone to occur when different trains configure protocol stack parameters separately.

[0018] The memory stores a computer program executable by the at least one processor, and the computer program is executed by the at least one processor so that the at least one processor can execute the railway safety protocol configuration method described in any embodiment of the present invention.

[0019] According to another aspect of the present invention, a computer-readable storage medium is provided, wherein the computer-readable storage medium stores computer instructions, and the computer instructions are used to enable a processor to implement the railway safety protocol configuration method described in any embodiment of the present invention when executed.

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

[0033] Embodiment 1

[0034] Figure 1 A flowchart of a railway safety protocol configuration method is provided for the first embodiment of the present invention. This embodiment is applicable to the case where a unified protocol stack parameter file is pre-burned in all trains associated with the train running section. The method can be executed by a railway safety protocol configuration device, which can be implemented in the form of hardware and / or software. The railway safety protocol configuration device can be configured in various general computing devices, for example, in an on-board train automatic protection system (Automatic Train Protection, referred to as ATP). Figure 1 As shown, the method includes:

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

[0036] The train running section is a specific area section that the train passes through from the starting point to the end point in the railway transportation network. The train running section contains multiple communication devices, such as multiple ground control centers (GCCs) deployed at intervals in the train section, on-board communication equipment contained in at least one train passing through the train running section, and other communication equipment in the train running section. Among them, each train contains at least two communication devices such as on-board ATP and on-board train tail.

[0037] The protocol stack parameter file is a parameter file that the train ATP needs to use when establishing communication with other communication devices in the train operation section. The protocol stack parameter file needs to be pre-burned into the non-volatile memory associated with the train ATP for use by the train ATP when establishing communication connections with other communication devices.

[0038] In the prior art, the protocol stack parameter file required by each train is written according to other communication devices that the train needs to establish communication with, and contains the protocol stack parameters of other communication devices that the train needs to establish communication connections with. The communication devices that each train needs to establish communication connections with are different, so the protocol stack parameter file of each train is unique and needs to be written and burned separately.

[0039] For example, if the onboard ATP1 of train 1 needs to establish communication with the onboard ATP2, onboard train tail, ground GCC1 and ground GCC2 of train 2 in the train operation section, it is necessary to write a protocol stack parameter file containing the protocol stack parameters of the above communication equipment and burn it into the flash memory of the onboard ATP1. If the onboard ATP2 of train 2 needs to establish communication with the onboard ATP1, onboard train tail, ground GCC1 and ground GCC3 of train 1 in the train operation section, it is necessary to write a protocol stack parameter file containing the protocol stack parameters of the above communication equipment and burn it into the flash memory of the onboard ATP1. Obviously, the protocol stack parameter files that need to be burned for the onboard ATP of trains 1 and 2 are different.

[0040] When there are a large number of trains, the above method is complex and error-prone in terms of programming and burning, and the errors can only be discovered when the trains establish communication connections, seriously affecting the normal communication of the trains.

[0041] In order to reduce writing and burning errors, in the embodiment of the present invention, the protocol stack parameter files burned into at least one train associated with the same train running section are the same, and both contain the protocol stack parameters of all communication devices in the train running section. The train can selectively use the protocol stack parameters contained in the protocol stack parameter file when establishing a communication connection.

[0042] During the on-board ATP initialization process, the protocol stack parameters of each communication device in the train operation 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 according to the identity code of each communication device. The protocol stack parameters of each communication device include the device layer parameters of the communication device and the session layer parameters between the communication device and the current on-board ATP.

[0043] S120. Based on the protocol stack parameters, configure the railway signal safety protocol array; the railway signal safety protocol array is used to establish a communication connection with the communication equipment in the train operation section.

[0044] In the embodiment of the present invention, according to the Railway Signal Safety Protocol I (RSSP-1) parameter composition principle, the railway signal safety protocol array associated with the current on-board ATP is further configured according to the read protocol stack parameters, so as to provide the on-board ATP with a parameter basis for establishing a communication connection. When the on-board ATP needs to establish a communication connection with the 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 signal safety protocol array includes the Safety Function Management Layer (SFM layer) data and the Communication Function Management Layer (CFM layer) data. The SFM layer data corresponding to each communication device constitutes the SFM array, and the CFM layer data corresponding to each communication device constitutes the CFM array.

[0046] According to the technical solution of the embodiment of the present invention, the on-board ATP obtains the protocol stack parameters of all communication devices in the train operation section by reading the pre-burned protocol parameter file, and then configures the railway signal safety protocol array based on the protocol stack parameters, which is used to establish a communication connection with other communication devices in the train operation section. By pre-burning a unified protocol stack parameter file in each train associated with the train operation section, the on-board ATP of each train can configure the railway signal safety protocol data based on the protocol stack parameter file, so as to provide a parameter basis for the train to establish communication with other communication devices. Compared with the method in which each train needs to burn different protocol stack parameter files, this solution can reduce the error rate of protocol stack parameter burning.

[0047] Embodiment 2

[0048] Figure 2a This is a flow chart of a railway safety protocol configuration method provided in the second embodiment of the present invention. This embodiment further refines the above embodiment and provides specific steps for configuring a railway signal safety protocol array based on protocol stack parameters, as well as specific steps after configuring a railway signal 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 operation section from the protocol stack parameter file; the protocol stack parameter files used by at least one train associated with the same train operation section are the same, and both contain the protocol stack parameters of all communication devices in the train operation section.

[0050] Optionally, the protocol stack parameter file includes a protocol stack data packet consisting of session layer parameters associated with the current on-board ATP and each type of communication equipment in the train operation section, and device layer parameters of each communication equipment in the current operation section.

[0051] When a train operation section contains a large number of communication devices, each communication device has corresponding device layer parameters and session layer parameters between the communication device and the current onboard ATP. This makes the protocol stack parameters of all communication devices occupy a large amount of storage space.

[0052] In order to reduce the space occupied by the protocol stack parameter file, the protocol stack parameters need to be compressed and stored. In this optional embodiment, the compression principle is to classify according to the common attributes and unique attributes in the protocol stack parameters. Specifically, the communication devices belonging to the same device type have the same session layer parameters in the protocol stack parameters, and the device layer parameters of each communication device are different. Therefore, the parameters of the same part can be compressed, that is, the corresponding session layer parameters of multiple communication devices belonging to the same device type are only stored once, and finally the protocol stack data packet is composed of the session layer parameters associated with the current on-board ATP and each type of communication device in the train operation section, and the device layer parameters of each communication device in the current operation section. Among them, the protocol stack data packet is part of the protocol stack parameter file.

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

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

[0055] In order to enable all trains associated with the same train operation section to burn a unified protocol stack parameter file, the protocol stack parameters of all communication devices in the train operation section are centrally written into the protocol stack parameter file. Figure 2c As shown, the train operation section includes on-board ATP1, on-board train tail 1, ground GCC1, on-board ATP2, on-board train tail 2 and ground GCC2, and the protocol stack parameter file includes the session layer parameters and device layer parameters associated with the above communication devices.

[0056] In order to reduce the space occupied by the protocol stack parameter file, the protocol stack parameters need to be compressed and stored. Figure 2dAs shown, the session layer parameters associated with communication devices belonging to the same device type are stored only once, that is, the session layer parameters stored in units of communication devices are modified to be stored in units of device types, and the device layer parameters of each communication device are saved separately to form a protocol stack data packet, saving a lot of storage space.

[0057] Furthermore, a binary file (bin file) consisting of a file header, a file length, a file version, a protocol stack data packet, and a file checksum is burned into the on-board ATP of each train in the train operation section.

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

[0059] Extract one communication device in the train running section as the current communication device in turn, extract the device layer parameters of the current communication device in the protocol stack parameter file according to the identity code of the current communication device, and read the device type of the current communication device in the device layer parameters;

[0060] Determine the session layer parameters between the current vehicle-mounted ATP and the current communication device according to the device type of the current communication device;

[0061] The device layer parameters of the current communication device and the session layer parameters between the current on-board ATP and the current communication device are taken as the protocol stack parameters of the current communication device, and are stored in the running memory of the current train. The operation of sequentially extracting one communication device in the train running section as the current communication device is returned to be executed until the protocol stack parameters of each communication device in the train running section are obtained.

[0062] In this optional embodiment, a specific scheme for reading the protocol stack parameters of each communication device in the train operation section in the protocol stack parameter file is provided: since the protocol stack parameters in the protocol stack parameter file are compressed, during the on-board ATP initialization process, the compressed parameters need to be decompressed and the protocol stack parameters of all communication devices need to be re-read. First, a communication device in the train operation section is extracted in turn as the current communication device, and the device layer parameters of the current communication device are extracted in the protocol stack parameter file according to the identity code of the current communication device. Then, the device layer parameters are parsed to obtain the device type of the current communication device. According to the device type of the current communication device, the session layer parameters between the current on-board 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 on-board ATP and the current communication device are stored in the running memory of the current train as the protocol stack parameters of the current communication device, and the operation of extracting a communication device in the train operation section as the current communication device in turn is returned to be executed until the protocol stack parameters of each communication device in the train operation section are obtained.

[0063] S220 . Construct a security function management layer array and a communication function management layer array according to the session layer parameters and device layer parameters of each communication device in the protocol stack parameters.

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

[0065] First, according to 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, wherein session layer parameter items and device layer parameter items associated with the security function management layer array, and session layer parameter items and device layer parameter items associated with the communication function management layer are pre-configured.

[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. Use the safety function management layer array and the communication function management layer array together as a railway signal safety protocol array.

[0068] In an embodiment of the present 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 the subsequent on-board ATP to establish communication with other communication equipment.

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

[0070] In the embodiment of the present invention, after receiving the communication connection task, the vehicle-mounted ATP first parses the communication connection task, reads the identity identifier of the terminal to be communicated contained therein, and obtains the protocol stack parameters associated with the terminal to be communicated according to the identity identifier.

[0071] S250. Reading protocol stack parameters associated with the terminal to be communicated from the railway signal safety protocol array according to the identity identifier.

[0072] In the embodiment of the present invention, according to the identity identification of the terminal to be communicated, the protocol stack parameters associated with the terminal to be communicated are read in the railway signal safety protocol array. Specifically, according to the identity identification, a part of the session layer parameters and device layer parameters associated with the terminal to be communicated are read in the security function management layer data of the railway signal safety protocol array. At the same time, another part of the session layer parameters and device layer parameters associated with the terminal to be communicated are read in the communication function management layer data of the railway signal safety protocol array. Finally, the parameter set is obtained as the protocol stack parameters associated with the terminal to be communicated.

[0073] S260: Establish a communication connection with the terminal to be communicated based on the protocol stack parameters associated with the terminal to be communicated.

[0074] In the embodiment of the present invention, after obtaining the protocol stack parameters associated with the communication terminal, the data to be sent is sent based on the railway signal safety protocol according to the obtained protocol stack parameters. Specifically, 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.

[0075] The technical solution of the embodiment of the present invention stores the protocol stack parameters of all communication devices in the train operation section in units of device type, compresses the volume of the protocol stack parameter file, can save the flash memory space of the on-board ATP, and based on the protocol stack parameters, adds a railway signal safety communication protocol stack between the application layer and the network layer to ensure communication stability and security.
