[0036] Embodiment 1

[0037] Figure 1 This is a flow chart of a method for modifying train data provided in the first embodiment of the present invention. This embodiment is applicable to the case where the train data modification is completed without relying on the driver to manually input data values. The method can be executed by a train data modification device, and the train data modification device can be implemented in the form of hardware and / or software, such as using ATP (Automatic Train Protection, train automatic protection system). Figure 1 As shown, the method includes:

[0038] S101. Acquire a data value to be modified for target train data through an external data interface of the target train, and determine whether the data value to be modified requires verification by a target driver according to a target data type of the target train data.

[0039] Among them, the target train refers to a train with a train data modification demand. The type of the target train can be a freight train, a passenger train or a high-speed train, etc. This embodiment does not limit the specific type of the target train. The external data interface refers to the data interface for the target train to communicate data with the outside. The target train can receive externally written information and transmit information to the outside using the external data interface. It can be understood that in this embodiment, the target train uses the external data interface to receive the data value to be modified written by the outside. The data value to be modified can be obtained in the following way: other personnel except the target driver edit the data value to be modified on the terminal device, and use the terminal device to call the external data interface to send the data value to be modified to the external data interface. The train automatic protection system further obtains the data value to be modified through the external data interface.

[0040] The target train stores at least one pre-configured candidate train data, which includes basic attribute data of the target train and operation data related to the operation of the target train, etc. The data types of the candidate train data include but are not limited to train type, train length, traction / braking parameters, maximum train speed, loading limit, axle load type, traction system received by the engine, airtight system and number of axles loaded on the train, etc. Among them, the traction / braking parameters also include traction model, braking model (braking reaction time, braking establishment time and braking deceleration, etc.) or braking percentage, braking position, vehicle-mounted correction factor and moment of inertia.

[0041] The target train data is stored in the target train, and refers to the candidate train data that needs to be modified, that is, the candidate train data whose data value needs to be modified. The data value to be modified refers to the data value corresponding to the target train data after the target train data is modified. For example, assuming that the current data value of the target train data is "A", the target train data is modified, and the data value "A" is changed to the data value "B", then the data value "B" is the data value to be modified. It can be understood that since the data value to be modified is input into the target train through an external data interface, it is not manually modified by the target driver himself, so it is necessary to further determine whether the data value to be modified requires verification by the target driver based on the target data class. The target data type refers to the data type of the target train data, that is, the data type of the train data that needs to be modified in terms of data value, and the target driver is the driver of the target train.

[0042] In one embodiment, the automatic train protection system (hereinafter referred to as the protection system) first determines whether the train operation mode currently in which the target train is located belongs to one of the preset mode sets, and if so, continues to determine whether the target train currently has valid candidate train data stored, and if so, detects in real time whether the external data interface receives the data value to be modified input from the outside, and if so, the protection system obtains the data value to be modified for the target train data through the external data interface. For example, if the protection system obtains the information "maximum train speed: X" through the external data interface, it determines that the target train data is "maximum train speed", and "X" is the data value to be modified.

[0043] Furthermore, the protection system matches the target data type of the target train data in the first type set and the second type set, respectively, wherein the first type set refers to a data type set that requires the target driver to verify the data value, and the second type set refers to a data type set that does not require the target driver to verify the data value.

[0044] If the target data type matches any data type in the first type set, it is determined that the data value to be modified requires verification by the target driver; if the target data type matches any data type in the second type set, it is determined that the data value to be modified does not require verification by the target driver.

[0045] S102. When it is determined that the data value to be modified requires verification by the target driver, determine the current train operation mode of the target train, and when it is determined that the train operation mode is the first operation mode, determine whether the target train is in a stationary state.

[0046] Among them, the first operating mode is one of full supervision mode (Full Supervision, FS), automatic driving mode (Automatic Driving, AD), partial supervision mode (Limited Supervision, LS), visual driving mode (OnSight, OS), manual driving mode (Staff Responsible, SR), standby mode (Stand By, SB) and unfitted mode (Unfitted, UN).

[0047] In one embodiment, when determining that the data value to be modified requires verification by the target driver, the protection system further determines the train operation mode that the target train is currently in. If the train operation mode that the target train is currently in is a full monitoring mode, an automatic driving mode, a partial monitoring mode, a visual driving mode, a manual driving mode, a standby mode, or an unequipped mode, it is further determined whether the target train is in a stationary state.

[0048] Optionally, the protection system determines the current running speed of the target train. If the running speed is determined to be zero, it is determined that the target train is in a stationary state; if the running speed is determined to be non-zero, it is determined that the target train is in a non-stationary state, that is, the target train is currently moving.

[0049] S103. When it is determined that the target train is in a stationary state, a verification message for the data value to be modified is generated for the target driver, and when the verification passes, the train data of the target train is modified according to the data value to be modified.

[0050] In one embodiment, when the protection system determines that the target train is stationary, it indicates that the target driver is in a safe driving environment at this time and can perform the verification operation without affecting driving safety. Therefore, the protection system generates a verification message for the data value to be modified based on the data value to be modified. For example, the content of the verification message can be "Can the data value of the target train data XX be modified to the data value to be modified ZZ, please review", etc. This embodiment only uses the above content as an example to illustrate the verification message, and does not limit the content of the verification message.

[0051] The protection system displays the verification message to the target driver through the human-machine interface DMI of the target train. The target driver verifies the data value to be modified according to the verification message. If the target driver passes the verification of the data value to be modified, he clicks the confirmation button on the human-machine interface DMI. If the verification passes, the protection system modifies the train data of the target train according to the data value to be modified. For example, assuming that the current data value of the target train data is B1 and the data value to be modified is B2, the protection system modifies the data value of the target train data from B1 to B2.

[0052] If the target driver fails to verify the data value to be modified, that is, the target driver believes that the data value to be modified is unreasonable, the target driver clicks the re-enter button on the human-machine interaction interface DMI, and the protection system displays the custom editing page to the target driver through the human-machine interaction interface DMI of the target train, so that the target driver can re-customize the data value of the target train data in the custom editing page. The protection system modifies the train data of the target train according to the data value customized by the target driver.

[0053] The embodiment of the present invention obtains the data value to be modified for the target train data through the external data interface of the target train, and finally after verification by the target driver, uses the data value to be modified to modify the train data of the target train, thereby eliminating the need for the driver to manually modify the train data, and only data value verification is required to achieve the modification of the train data, thereby reducing the operating burden of the driver, reducing the possibility of train data modification errors, and further improving the operation safety of the train.

[0054] Embodiment 2

[0055] Figure 2 This is a flow chart of a method for modifying train data provided by Embodiment 2 of the present invention. This embodiment further optimizes and expands the above embodiment and can be combined with the above optional implementations. Figure 2 As shown, the method includes:

[0056] S201. Acquire a data value to be modified for target train data through an external data interface of the target train, and determine whether the data value to be modified requires verification by a target driver according to a target data type of the target train data.

[0057] S202. When it is determined that the data value to be modified requires verification by the target driver, determine the current train operation mode of the target train.

[0058] S203. When it is determined that the train operation mode is the second operation mode, determine whether the target train currently exits the passing program.

[0059] The second operation mode is the trip protection mode (TP) or the post trip protection mode (PT). The overtaking procedure refers to the process in railway transportation when two trains are running in the same direction and the latter train directly overtakes the leading train without stopping at the station ahead. The overtaking procedure usually occurs on double-track railways to ensure that trains can run efficiently and safely.

[0060] In one embodiment, if the protection system determines that the train operation mode is an overrun protection mode or a post-overrun protection mode, it further determines whether the target train currently exits the overrun program. If it is determined that the target train currently has not exited the overrun mode, the protection system continues to wait until it is determined that the target train currently has exited the overrun program, and then jumps to execute S204.

[0061] S204. When it is determined that the target train has currently exited the overtaking procedure, redetermine the current train operation mode of the target train, and when it is determined that the train operation mode is the third operation mode, generate a verification message for the data value to be modified for the target driver.

[0062] Among them, the third operating mode is one of the full monitoring mode, partial monitoring mode, visual driving mode, manual driving mode and unequipped mode.

[0063] In one embodiment, when the protection system determines that the target train has currently exited the overtaking procedure, it redetermines the current train operation mode of the target train. If the train operation mode is determined to be a full monitoring mode, a partial monitoring mode, a visual driving mode, a manual driving mode or an unequipped mode, the verification message will be displayed to the target driver through the human-machine interaction interface DMI of the target train.

[0064] S205. If the verification is successful, modify the target train data according to the data value to be modified.

[0065] In one embodiment, the target driver verifies the data value to be modified according to the verification message. If the target driver passes the verification of the data value to be modified, he clicks the confirmation button on the human-computer interaction interface DMI. The protection system modifies the target train data according to the data value to be modified if the verification is passed.

[0066] If the target driver fails to verify the data value to be modified, that is, the target driver believes that the data value to be modified is unreasonable, the target driver clicks the re-enter button on the human-machine interaction interface DMI, and the protection system displays the custom editing page to the target driver through the human-machine interaction interface DMI of the target train, so that the target driver can re-customize the data value of the target train data in the custom editing page. The protection system modifies the train data of the target train according to the data value customized by the target driver.

[0067] By determining whether the target train currently exits the overtaking program when the train operation mode is determined to be the second operation mode; re-determining the current train operation mode of the target train when it is determined that the target train has currently exited the overtaking program, and generating a verification message for the data value to be modified for the target driver when it is determined that the train operation mode is the third operation mode; and modifying the train data of the target train according to the data value to be modified when the verification is passed, the beneficial effects are:

[0068] First, the driver does not need to manually modify the train data. The train data can be modified by simply verifying the data value, which reduces the driver's operating burden, reduces the possibility of train data modification errors, and further improves the operation safety of the train.

[0069] Secondly, since when the train operation mode is the second operation mode, a verification message for the data value to be modified will be generated for the target driver only when the target train exits the overtaking program. This can avoid the problem of being reminded of the verification message when running the overtaking program, which can easily distract the target driver and create a driving safety hazard, further ensuring the operation safety of the target train.

[0070] Embodiment 3

[0071] Figure 3 This is a flow chart of a method for modifying train data provided by Embodiment 3 of the present invention. This embodiment further optimizes and expands the above embodiment and can be combined with the above optional implementations. Figure 3 As shown, the method includes:

[0072] S301. Obtain a data value to be modified for target train data through an external data interface of the target train, and determine whether the data value to be modified requires verification by a target driver according to a target data type of the target train data.

[0073] S302. When it is determined that the data value to be modified requires verification by the target driver, determine the current train operation mode of the target train, and when it is determined that the train operation mode is the first operation mode, determine whether the target train is in a stationary state.

[0074] S303: When it is determined that the target train is in a non-stationary state, applying a common brake to the target train until the target train is in a stationary state, and generating a first braking reason notification message for the target driver.

[0075] In one embodiment, when the protection system determines that the target train is in a non-stationary state, it indicates that the target driver is not in a safe driving environment at this time. If a verification message is directly prompted, it will affect driving safety. Therefore, the protection system applies common braking to the target train to slow down the target train, and determines in real time whether the target train is in a stationary state. If it is determined that the target train is in a stationary state due to common braking deceleration, a first braking reason notification message is generated for the target driver according to the reason for applying common braking. For example, the content of the first braking reason notification message can be "You need to perform a data value verification operation, and common braking is applied to ensure driving safety", etc. This embodiment only uses the above content as an example to illustrate the first braking reason notification message, and does not limit the content of the first braking reason notification message.

[0076] S304. When the target driver performs a confirmation operation on the first brake cause notification information, release the normal brake for the target train, and generate a verification message for the data value to be modified for the target driver.

[0077] In one embodiment, the protection system displays the first braking reason notification information to the target driver through the human-machine interface DMI of the target train. After the target driver browses the first braking reason notification information, he clicks the confirmation button on the human-machine interface DMI, and the protection system releases the common brake for the target train so that the target train can resume operation when the target driver performs a confirmation operation on the first braking reason notification information. In addition, a verification message for the data value to be modified is generated according to the data value to be modified, and then the verification message is displayed to the target driver through the human-machine interface DMI of the target train.

[0078] S305. If the verification is successful, modify the target train data according to the data value to be modified.

[0079] By applying common braking to the target train until the target train is in a stationary state when it is determined that the target train is in a non-stationary state, and generating first braking reason notification information for the target driver; when the target driver applies a confirmation operation to the first braking reason notification information, releasing common braking for the target train, and generating a verification message for the data value to be modified for the target driver; and modifying the train data of the target train according to the data value to be modified when the verification is passed, the beneficial effects are:

[0080] First, the driver does not need to manually modify the train data. The train data can be modified by simply verifying the data value, which reduces the driver's operating burden, reduces the possibility of train data modification errors, and further improves the operation safety of the train.

[0081] Secondly, since the verification message for the data value to be modified is not generated until the target train is in a stationary state and the common brake is applied to the target train when the train is in a non-stationary state, it can avoid the problem that the target train is reminded of the verification message when the train is in a non-stationary state, which may easily distract the target driver and cause driving safety hazards, thereby further ensuring the operation safety of the target train.

[0082] Thirdly, the first braking reason notification information is generated for the target driver, so that the target driver can know the reason for braking in time, avoiding panic of the target driver and affecting driving safety, and further ensuring the operation safety of the target train.

[0083] Embodiment 4

[0084] Figure 4 This is a flow chart of a method for modifying train data provided by Embodiment 4 of the present invention. This embodiment further optimizes and expands the above embodiment and can be combined with the above optional implementations. Figure 4 As shown, the method includes:

[0085] S401. Obtain a data value to be modified for target train data through an external data interface of the target train, and determine whether the data value to be modified requires verification by a target driver according to a target data type of the target train data.

[0086] S402: When it is determined that the data value to be modified does not require verification by the target driver, determine whether the target data type is the first data type.

[0087] The first data type is one of a train type, an axle load type, a traction system accepted by the engine, and a loading limit.

[0088] In one embodiment, when determining that the data value to be modified does not require verification by the target driver, the protection system further determines whether the target data type is a train type, an axle load type, a traction system accepted by the engine, or a loading limit.

[0089] S403. When it is determined that the target data type is not the first data type, generate data modification notification information for the data value to be modified for the target driver, and modify the target train data according to the data value to be modified.

[0090] In one implementation, when the protection system determines that the target data type is not a train type, an axle load type, a traction system accepted by the engine, or a loading limit, a data modification notification message is generated for the data value to be modified. For example, the content of the data modification notification message may be "the data value of the target train data XX is modified to the data value to be modified ZZ, please be informed", etc. This embodiment only uses the above content as an example to illustrate the data modification notification message, and does not limit the content of the data modification notification message.

[0091] The protection system displays the data modification notification information to the target driver through the human-machine interface DMI of the target train. Further, the protection system modifies the train data of the target train according to the data value to be modified.

[0092] By determining whether the target data type is the first data type when it is determined that the data value to be modified does not need to be verified by the target driver; generating data modification notification information for the data value to be modified for the target driver when it is determined that the target data type is not the first data type, and performing train data modification on the target train data according to the data value to be modified, the beneficial effects are:

[0093] First, the train data can be modified without the driver performing any operation, which further reduces the driver's operating burden, reduces the possibility of train data modification errors, and further improves the operation safety of the train.

[0094] Secondly, generating data modification notification information for the data value to be modified for the target driver can enable the target driver to perceive the modification of the train data in a timely manner, which is conducive to ensuring the effective maintenance of the subsequent train data.

[0095] Embodiment 5

[0096] Figure 5 This is a flow chart of a method for modifying train data provided by Embodiment 5 of the present invention. This embodiment further optimizes and expands the above embodiment and can be combined with the above optional implementations. Figure 5 As shown, the method includes:

[0097] S501. Obtain a data value to be modified for target train data through an external data interface of the target train, and determine whether the data value to be modified requires verification by a target driver according to a target data type of the target train data.

[0098] S502: When it is determined that the data value to be modified does not require verification by the target driver, determine whether the target data type is the first data type.

[0099] S503. When it is determined that the target data type is the first data type, determine the current train operation mode of the target train, and when the train operation mode is the fourth operation mode, determine whether the target train stores driving permission information and track description information.

[0100] The fourth operation mode is one of the unequipped mode, the manual driving mode and the reckless protection mode. The driving permission information is also called MA (Movement Authority), which refers to the start command of the train operation. The track description information refers to the information used to describe the track where the train is located.

[0101] In one embodiment, when the protection system determines that the target data type is the first data type, it further determines whether the train operation mode is an unequipped mode, a manual driving mode, or an over-advance protection mode. If so, it further determines whether the target train stores the driving permission information issued by the RBC (Radio Block Center) and the track description information.

[0102] S504. When it is determined that the target train does not store driving permission information or track description information, generate data modification notification information for the data value to be modified for the target driver, and modify the train data of the target train according to the data value to be modified.

[0103] In one embodiment, when the protection system determines that the target train does not store the driving permission information or track description information issued by the RBC, it generates data modification notification information for the data value to be modified. The protection system displays the data modification notification information to the target driver through the human-machine interface DMI of the target train. Further, the protection system modifies the train data of the target train according to the data value to be modified.

[0104] By determining that the target data type is the first data type, determining the current train operation mode of the target train, and determining whether the target train stores driving permission information and track description information when the train operation mode is the fourth operation mode; generating data modification notification information for the data value to be modified for the target driver when it is determined that the target train does not store driving permission information or track description information, and modifying the train data of the target train according to the data value to be modified, the beneficial effects are:

[0108] Figure 6 This is a flowchart of a method for modifying train data provided by Embodiment 6 of the present invention. This embodiment further optimizes and expands the above embodiment and can be combined with the above optional implementations. Figure 6 As shown, the method includes:

[0109] S601. Obtain a data value to be modified for target train data through an external data interface of the target train, and determine whether the data value to be modified requires verification by a target driver according to a target data type of the target train data.

[0110] S602: When it is determined that the data value to be modified does not require verification by the target driver, determine whether the target data type is the first data type.

[0111] S603. When it is determined that the target data type is the first data type, determine the current train operation mode of the target train, and when the train operation mode is the fourth operation mode, determine whether the target train stores driving permission information and track description information.

[0112] S604: When it is determined that the target train stores driving permission information and track description information, determine whether the target train is in a stationary state.

[0113] In one embodiment, when the protection system determines that the target train stores both the driving permission information issued by the RBC and the track description information, it further determines whether the target train is in a stationary state.

[0114] S605. When it is determined that the target train is in a stationary state, generate data modification notification information for the data value to be modified for the target driver, and modify the train data of the target train according to the data value to be modified.

[0115] In one embodiment, when the protection system determines that the target train is stationary, it indicates that the target driver is in a safe driving environment at this time and can consult the data modification notification information without affecting driving safety. Therefore, the protection system generates data modification notification information for the data value to be modified based on the data value to be modified. The protection system displays the data modification notification information to the target driver through the human-machine interface DMI of the target train. Further, the protection system modifies the train data of the target train based on the data value to be modified.

[0116] By determining whether the target train is in a stationary state when it is determined that the target train stores driving permission information and track description information; generating data modification notification information for the data value to be modified for the target driver when it is determined that the target train is in a stationary state, and modifying the train data of the target train according to the data value to be modified, the beneficial effects are:

[0117] First, the train data can be modified without the driver performing any operation, which further reduces the driver's operating burden, reduces the possibility of train data modification errors, and further improves the operation safety of the train.

[0118] Secondly, generating data modification notification information for the data value to be modified for the target driver can enable the target driver to perceive the modification of the train data in a timely manner, which is conducive to ensuring the effective maintenance of the subsequent train data.

[0119] Thirdly, since data modification notification information for the data value to be modified is generated for the target driver only when the target train is in a stationary state, it can avoid the problem of data modification notification information being reminded when the target train is not in a stationary state, which may easily distract the target driver and cause driving safety hazards, thereby further ensuring the operation safety of the target train.

[0120] Embodiment 7

[0121] Figure 7 This is a flow chart of a method for modifying train data provided by Embodiment 7 of the present invention. This embodiment further optimizes and expands the above embodiment and can be combined with the above optional implementation modes. Figure 7 As shown, the method includes:

[0122] S701. Obtain the data value to be modified for the target train data through the external data interface of the target train, and determine whether the data value to be modified requires verification by the target driver according to the target data type of the target train data.

[0123] S702: When it is determined that the data value to be modified does not require verification by the target driver, determine whether the target data type is the first data type.

[0124] S703. When it is determined that the target data type is the first data type, determine the current train operation mode of the target train, and when the train operation mode is the fourth operation mode, determine whether the target train stores driving permission information and track description information.

[0125] S704: When it is determined that the target train stores driving permission information and track description information, determine whether the target train is in a stationary state.

[0126] S705. When it is determined that the target train is in a non-stationary state, apply common braking to the target train until the target train is in a stationary state, and generate second braking reason notification information for the target driver.

[0127] In one embodiment, when the protection system determines that the target train is in a non-stationary state, it indicates that the target driver is not in a safe driving environment at this time. If the data modification notification information is directly reminded, it will affect driving safety. Therefore, the protection system applies common braking to the target train to slow down the target train, and determines in real time whether the target train is in a stationary state. If it is determined that the target train is in a stationary state due to common braking deceleration, a second braking reason notification information is generated for the target driver according to the reason for applying common braking. For example, the content of the second braking reason notification information can be "You need to check the data modification notification information, and common braking is applied to ensure driving safety", etc. This embodiment only uses the above content as an example to illustrate the second braking reason notification information, and does not limit the content of the second braking reason notification information.

[0128] S706. When the target driver performs a confirmation operation on the second brake reason notification information, release the normal brake for the target train, and generate data modification notification information for the data value to be modified for the target driver.

[0129] In one embodiment, the protection system displays the second brake cause notification information to the target driver through the human-machine interface DMI of the target train. After the target driver browses the second brake cause notification information, he clicks the confirmation button on the human-machine interface DMI, and the protection system releases the common brake for the target train so that the target train can resume operation when the target driver applies a confirmation operation to the second brake cause notification information. In addition, data modification notification information for the data value to be modified is generated according to the data value to be modified, and then the data modification notification information is displayed to the target driver through the human-machine interface DMI of the target train.

[0130] S707. Modify the target train data according to the data value to be modified.

[0131] By applying common braking to the target train until the target train is in a stationary state when it is determined that the target train is in a non-stationary state, and generating second braking reason notification information for the target driver; releasing common braking for the target train when the target driver performs a confirmation operation on the second braking reason notification information, and generating data modification notification information for the data value to be modified for the target driver; and modifying the train data of the target train according to the data value to be modified, the beneficial effects are:

[0132] First, the train data can be modified without the driver performing any operation, which further reduces the driver's operating burden, reduces the possibility of train data modification errors, and further improves the operation safety of the train.

[0133] Secondly, generating data modification notification information for the data value to be modified for the target driver can enable the target driver to perceive the modification of the train data in a timely manner, which is conducive to ensuring the effective maintenance of the subsequent train data.

[0134] Secondly, since the target train is in a non-stationary state, the common brake is applied to the target train until it is in a stationary state, and the data modification notification information for the data value to be modified will not be generated. This can avoid the problem that the target train is reminded of data modification notification information when it is in a non-stationary state, which may easily distract the target driver and cause driving safety hazards, thereby further ensuring the operation safety of the target train.

[0138] S802: When it is determined that the data value to be modified does not require verification by the target driver, determine whether the target data type is the first data type.

[0139] S803: When it is determined that the target data type is the first data type, determine the current train operation mode of the target train.

[0140] S804. When the train operation mode is the fifth operation mode, generate data modification notification information for the data value to be modified for the target driver, and modify the train data of the target train according to the data value to be modified.

[0141] Among them, the fifth operation mode is a standby mode or a post-failure protection mode.

[0142] In one embodiment, the protection system determines whether the train operation mode is a standby mode or a post-risk protection mode, and if so, generates data modification notification information for the data value to be modified according to the data value to be modified. The protection system displays the data modification notification information to the target driver through the human-machine interface DMI of the target train. Further, the protection system modifies the train data of the target train according to the data value to be modified.

[0143] By generating data modification notification information for the data value to be modified for the target driver when the train operation mode is the fifth operation mode, and modifying the train data of the target train data according to the data value to be modified, the beneficial effects are:

[0144] First, the train data can be modified without the driver performing any operation, which further reduces the driver's operating burden, reduces the possibility of train data modification errors, and further improves the operation safety of the train.

[0145] Secondly, generating data modification notification information for the data value to be modified for the target driver can enable the target driver to perceive the modification of the train data in a timely manner, which is conducive to ensuring the effective maintenance of the subsequent train data.

[0151] S904: When the train operation mode is the sixth operation mode, determine whether the target train is in a stationary state.

[0152] Among them, the sixth operating mode is one of the full monitoring mode, automatic driving mode, partial monitoring mode and visual driving mode.

[0153] In one embodiment, the protection system determines whether the train operation mode is a full monitoring mode, an automatic driving mode, a partial monitoring mode, or a visual driving mode, and if so, further determines whether the target train is stationary.

[0154] S905. When it is determined that the target train is in a stationary state, generate data modification notification information for the data value to be modified for the target driver, and modify the train data of the target train according to the data value to be modified.

[0155] In one embodiment, when the protection system determines that the target train is stationary, it indicates that the target driver is in a safe driving environment at this time and can consult the data modification notification information without affecting driving safety. Therefore, the protection system generates data modification notification information for the data value to be modified based on the data value to be modified. The protection system displays the data modification notification information to the target driver through the human-machine interface DMI of the target train. Further, the protection system modifies the train data of the target train based on the data value to be modified.

[0156] By determining whether the target train is in a stationary state when the train operation mode is the sixth operation mode; generating data modification notification information for the data value to be modified for the target driver when it is determined that the target train is in a stationary state, and modifying the train data of the target train according to the data value to be modified, the beneficial effects are:

[0157] First, the train data can be modified without the driver performing any operation, which further reduces the driver's operating burden, reduces the possibility of train data modification errors, and further improves the operation safety of the train.

[0158] Secondly, generating data modification notification information for the data value to be modified for the target driver can enable the target driver to perceive the modification of the train data in a timely manner, which is conducive to ensuring the effective maintenance of the subsequent train data.

[0159] Thirdly, since data modification notification information for the data value to be modified is generated for the target driver only when the target train is in a stationary state, it can avoid the problem of data modification notification information being reminded when the target train is not in a stationary state, which may easily distract the target driver and cause driving safety hazards, thereby further ensuring the operation safety of the target train.
