Consistency locking method and system for smart rail cross-line charging configuration

Abstract

This invention relates to the field of intelligent rail transit system operation control technology, and provides a method and system for interlocking consistent charging configuration across lines. After an intelligent rail vehicle enters a preset triggering interval of a target charging station, the target charging position is first determined based on the current task line and the charging position status at the station. Then, a target configuration message is generated based on the cross-line charging configuration record corresponding to the target charging position. Until the onboard readback message is consistent with the target configuration message and the target charging position is still idle, the vehicle is continuously prohibited from entering the charging handshake process. This ensures that when an intelligent rail vehicle crosses a line to enter a target charging station, it is only allowed to enter the charging handshake process when the target charging position, onboard charging control configuration, target parking position parameter record, onboard HMI interface, and charging handshake parameter group are all consistent and the target charging position is still idle.

Description

Technical Field

[0001] This invention relates to the field of intelligent rail transit system operation control technology, and more specifically, to a method and system for intelligent rail transit cross-line charging configuration consistency interlocking. Background Technology

[0002] Existing intelligent rail transit (IRT) vehicles typically use onboard energy storage for power supply and receive rapid refueling at the first and last stops or designated stations. Under single-line operation conditions, the target charging station, charging position, onboard charging control configuration, parking parameters, onboard HMI (Human Machine Interface), and charging handshake parameter group for IRT vehicles are usually fixed. After the IRT vehicle enters the target charging station, the driver selects the corresponding charging position on the onboard HMI interface. The onboard control system then calls the preset charging control configuration corresponding to the target charging station or the charging position to complete parking confirmation, pantograph raising, and charging handshake.

[0003] The above methods can meet basic charging needs under conditions of single line, fixed charging station, fixed charging position, and fixed onboard charging control configuration. However, in the scenario of integrated operation of multiple intelligent rail lines, the same intelligent rail vehicle may perform tasks on different lines and enter target charging stations belonging to different lines. At this time, the intelligent rail vehicle's current task line, target charging station, physical charging position in the station, onboard charging control configuration, parking parameters, onboard HMI interface, and charging handshake parameter group no longer naturally maintain a single fixed correspondence. If the static position selection and static configuration calling method under the single-line condition is still used, inconsistencies may occur between the charging control configuration loaded by the onboard control system, the charging position information displayed on the onboard HMI interface, the charging position status on the station side, and the charging handshake parameter group, thereby increasing the risk of parking errors, pantograph lifting abnormalities, or handshake failures. Under the conditions of intelligent rail vehicle cross-line operation, onboard software upgrades, HMI interface integration, station-side charging resource sharing, and unified scheduling by the comprehensive management platform, this is a configuration consistency risk that needs to be prevented in advance during the charging preparation phase.

[0004] Existing solutions for intelligent rail transit (IRT) vehicle charging control, power supply mode switching, charging space matching, and charging configuration message control typically address issues such as whether an IRT vehicle has entered charging mode, switching power supply modes, matching the IRT vehicle with a parking space, or exchanging messages with the charger. However, these solutions do not establish a pre-charging handshake consistency interlocking mechanism for IRT multi-line integrated operation scenarios, addressing the consistency between the current task line, target charging station, target charging position, onboard charging control configuration, target parking position parameter record, onboard HMI interface, and charging handshake parameter group. Therefore, a cross-line charging configuration consistency interlocking method is needed to ensure that when an IRT vehicle crosses a line to enter a target charging station, it is only allowed to enter the charging handshake process if the target charging position, onboard charging control configuration, target parking position parameter record, onboard HMI interface, and charging handshake parameter group are all verified to be consistent, and the target charging position is still idle. Summary of the Invention

[0005] To address the issue of existing solutions lacking a consistency interlocking mechanism before charging handshake, this invention provides a method and system for consistency interlocking of intelligent rail transit charging configuration across lines. This ensures that when an intelligent rail transit vehicle crosses a line to enter a target charging station, it is only allowed to enter the charging handshake process if the target charging position, onboard charging control configuration, target parking position parameter record, onboard HMI interface, and charging handshake parameter group are all verified to be consistent, and the target charging position is still in an idle state.

It does not output the charging handshake enable state, and outputs the state that there is no available charging position to the integrated management platform. When the effective charging potential set If not empty, proceed to step S105.

Furthermore, when the charging position is enabled, the cross-line charging configuration record is identified as a matching record. If a matching record exists, the integrated management platform reads the target on-board charging control configuration number from that matching record.

Remove from the set of valid charging positions; If the set of valid charging bits is empty after removal, then the charging handshake enable state is taken. It does not output the charging handshake enable state, and outputs the state of no complete cross-line charging configuration to the integrated management platform. If the set of valid charging positions is not empty after elimination, return to step S105 to reselect the target charging position.

[0011] In a preferred embodiment, in step S107, a target configuration message is generated based on the comparison result. hour: when At that time, the integrated management platform generates the target configuration message. and in the target configuration message Write the configuration switching instruction field to be switched; when At that time, the integrated management platform generates the target configuration message. and in the target configuration message Write "No switching required" in the configuration switching instruction field.

[0012] In a preferred embodiment, step S108, where the vehicle control system and the vehicle HMI interface complete the configuration loading, includes: The vehicle control system based on the target configuration message Load the target parking position parameter record, target on-board charging control configuration, and target charging handshake parameter group; The vehicle HMI interface is configured according to the target message.

It does not output the charging handshake enable status, but outputs the configuration loading failure status to the integrated management platform.

[0015] In a preferred embodiment, in step S111, if the target charging position If it has already entered the occupied state, then retrieve the charging handshake enable state. No charging handshake enable state is output, and the target charging position is set.

Then, it generates a target configuration message based on the cross-line charging configuration record corresponding to the target charging position. Until the onboard readback message matches the target configuration message and the target charging position remains idle, the vehicle is continuously prohibited from entering the charging handshake process. This ensures that when the intelligent rail vehicle crosses a line to enter the target charging station, it is only allowed to enter the charging handshake process when the target charging position, onboard charging control configuration, target parking position parameter record, onboard HMI interface, and charging handshake parameter group are all verified to be consistent, and the target charging position remains idle. Wherein: This invention uses the current task line identifier Adaptation relationship and occupancy status Constructing a set of effective charging potentials It can eliminate candidate charging positions that are known to be unsuitable for the current task line or that are already occupied before determining the target charging position, thereby reducing the risk of vehicles operating across lines entering the wrong charging position configuration process; This invention determines the target parking position parameter record number by recording the same cross-line charging configuration. Target on-board charging control configuration number Vehicle HMI charging interface number and charging handshake parameter group number This ensures that the control configuration, stop parameters, interface configuration, and handshake parameters corresponding to the target charging position are consistent, thereby reducing the risk of inconsistency caused by independent selection of different configuration items. This invention uses the target configuration message Simultaneously, the message is sent to the vehicle control system and the vehicle HMI interface, and is read back from the vehicle. Performing field consistency checks can confirm whether the loading results of the vehicle control system and vehicle HMI interface are consistent with the target configuration before entering the charging handshake. This invention will... and As a common necessary condition for outputting the charging handshake enable state, it can prevent the vehicle from entering the charging handshake process when the target configuration is not read back in agreement or the target charging position is occupied. This invention uses the target charging position When a device becomes occupied, it is removed from the set of valid charging positions and a new target charging position is determined. This prevents the system from continuing to use the configuration of an invalid target charging position in the subsequent charging handshake process. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0022] To ensure that when an intelligent rail transit vehicle (IRT) crosses a line to enter a target charging station, it is only allowed to enter the charging handshake process if the target charging position, onboard charging control configuration, target parking parameter record, onboard HMI interface, and charging handshake parameter group are all consistent, and the target charging position is still idle, this invention provides an IRT cross-line charging configuration consistency interlocking method. This method does not simply select a charging position or switch onboard configurations. Instead, after the IRT vehicle enters a preset trigger interval of the target charging station, it first determines the target charging position based on the current task line and the station-side charging position status. Then, it generates a target configuration message based on the cross-line charging configuration record corresponding to the target charging position. Until the onboard readback message matches the target configuration message and the target charging position remains idle, the vehicle is continuously prohibited from entering the charging handshake process.

[0032] Candidate charging spot The occupancy status is recorded as ,in Indicates occupancy. This indicates that the charging position is idle. The occupancy status is determined by the station-side charging position status acquisition unit based on the vehicle arrival detection signal, the charging controller's operating status, the charging circuit occupancy status, or the station-side interlocking status.

[0033] When any of the above states indicate a candidate charging position When a vehicle is parked, charging, the charging circuit is occupied, or the station-side interlock is not released, take the following:

[0049] A cross-line charging configuration record refers to a data record stored in the integrated management platform or station-side control equipment. Each cross-line charging configuration record corresponds to a target charging station, a physical charging position, and at least one task line authorized to use that charging position. This cross-line charging configuration record is created after vehicle modification, target charging station commissioning, on-board HMI interface configuration, on-board charging control configuration, and charging handshake parameter configuration are completed. The fields for each cross-line charging configuration record are as follows: Target charging station sign; Charging position indicator; The line identifier that allows the use of this charging position; Charging position is enabled; Target stop parameter record number; On-board charging control configuration number; Vehicle HMI interface number; Charging handshake parameter group number.

[0059] When any field is inconsistent, take:

[0060] The charging handshake enable state is recorded as ,in This indicates that the vehicle control system is allowed to enter the charging handshake process. This indicates that the vehicle control system is prohibited from entering the charging handshake process.

[0061] when At this time, the integrated management platform or vehicle control system outputs a charging handshake enable status, allowing the vehicle to enter the parking confirmation, pantograph raising and charging handshake process.

[0062] when If the integrated management platform or vehicle control system does not output the charging handshake enable state, the vehicle must not enter the pantograph raising and charging handshake process.

[0063] In view of the above description, such as Figure 2 As shown in the figure, an embodiment of the present invention provides a method for consistent interlocking of intelligent rail transit cross-line charging configuration, which includes the following steps: S101, after the vehicle enters the preset trigger zone of the target charging station, the integrated management platform reads the current task route identifier from the vehicle operation task record. It also reads the next target charging station identifier from the vehicle operation task record as the target charging station identifier. .

[0064] S102, the integrated management platform reads the target charging station's basic configuration record.

[0066] When the cross-line charging configuration record contains the task line identifier that allows the use of this charging position, the task line identifier is included. And when the charging position is enabled, the adaptation relationship is taken. .

[0067] Otherwise, use the fit relationship. .

[0068] S104, based on adaptation relationship and occupancy status Construct the set of effective charging positions, represented as:

[0069] When the effective charging potential set When empty, retrieve the charging handshake enable state. It does not output the charging handshake enable state, and outputs the state that there is no available charging position to the integrated management platform.

[0070] When the effective charging potential set If not empty, proceed to step S105.

[0071] S105, based on the vehicle's current location Reference parking coordinates of each valid charging position Positional deviation to determine the target charging position , is represented as:

[0072] S106, the integrated management platform is based on the target charging station Target charging position and the current mission route Query cross-line charging configuration records.

[0073] When a certain cross-line charging configuration record simultaneously satisfies the target charging station identifier equal to Charging position indicator equals The task line identifier that allows the use of this charging position includes the current task line identifier. When the charging position is enabled, the cross-line charging configuration record is identified as a matching record.

[0074] If a matching record exists, the integrated management platform reads the target on-board charging control configuration number from that matching record. Target stop parameter record number Target vehicle HMI interface number Target charging handshake parameter group number .

[0075] If no matching record is found, then the target charging position will be... Removed from the set of valid charging positions.

[0076] If the set of valid charging bits is empty after removal, then the charging handshake enable state is taken. It does not output the charging handshake enable state, and outputs the state of no complete cross-line charging configuration to the integrated management platform.

[0077] If the set of valid charging positions is not empty after elimination, return to step S105 to reselect the target charging position.

[0078] S107, The vehicle control system returns the currently loaded vehicle charging control configuration number. .

[0079] The integrated management platform compares the currently loaded on-board charging control configuration numbers of the vehicles. With the target on-board charging control configuration number .

[0080] when At that time, the integrated management platform generates the target configuration message. and in the target configuration message Write the switch command field in the configuration settings to be switched.

[0081] when At that time, the integrated management platform generates the target configuration message. and in the target configuration message Write "No switching required" in the configuration switching instruction field.

[0082] The target configuration message This includes the target charging station number field, the target charging position number field, the target parking position parameter record number field, the target vehicle charging control configuration number field, the vehicle HMI interface number field, the charging handshake parameter group number field, and the configuration switching instruction field.

[0083] S108, send the target configuration message Simultaneously, the data is distributed to the vehicle control system and the vehicle HMI interface.

[0084] The vehicle control system based on the target configuration message Load the target parking position parameter record, target on-board charging control configuration, and target charging handshake parameter group.

[0085] The vehicle HMI interface is configured according to the target message. Switch to the target charging station page to view the target charging location. It also identifies unsuitable candidate charging spots for the current task route.

[0086] S109, After the vehicle control system and vehicle HMI interface have completed configuration loading, the following fields are returned: The fields returned by the vehicle control system include the loaded target parking position parameter record number, the loaded vehicle charging control configuration number, and the loaded charging handshake parameter group number.

[0087] The fields returned by the vehicle HMI interface include the page number of the loaded target charging station, the page number of the displayed target charging spot, and the page number of the loaded vehicle HMI interface.

[0088] The integrated management platform combines the return fields from the vehicle control system and the vehicle HMI interface into a vehicle readback message. and read back the message from the vehicle. With target configuration message Perform field comparison.

[0089] When the target charging station number, target charging position number, target parking position parameter record number, target on-board charging control configuration number, on-board HMI interface number, and charging handshake parameter group number are all consistent, the consistency determination result is determined. Proceed to step S111.

[0090] Otherwise, the consistency determination result is determined. Proceed to step S110.

[0091] S110, when At that time, the charging handshake enable state is obtained. It does not output the charging handshake enable status and performs corresponding reprocessing based on the inconsistency field.

[0092] When the consistency determination result shows that the target on-board charging control configuration number is inconsistent, return to step S107 and regenerate the configuration switching instruction field to the target configuration message that needs to be switched. .

[0093] If the consistency determination result shows that the target parking parameter record number, the vehicle HMI interface number, or the charging handshake parameter group number are inconsistent, return to step S107 and regenerate the target configuration message. .

[0094] If the retransmission is still inconsistent, retrieve the charging handshake enable state. It does not output the charging handshake enable status, but outputs the configuration loading failure status to the integrated management platform.

[0095] S111, when At that time, the station-side charging position status acquisition unit verifies the target charging position. The state of being occupied.

[0096] If the target charging location If still in an idle state, then retrieve the charging handshake enable state. It outputs the charging handshake enable state, allowing the vehicle control system to enter the charging handshake process.

[0097] If the target charging location If it has already entered the occupied state, then retrieve the charging handshake enable state. No charging handshake enable state is output, and the target charging position is set. Remove it from the set of valid charging positions and return to step S105 to re-execute the target charging position selection.

[0098] Therefore, the charging handshake enable state is satisfied:

[0099] That is, the system will only allow the vehicle control system to enter the charging handshake process if the target configuration message is consistent with the vehicle readback message and the target charging position is still idle.

[0103] The integrated management platform reads the set of candidate charging positions from the basic configuration records of the target charging station:

[0104] in, , and Corresponding to the target charging station There are three actual physical charging positions inside.

[0105] The station-side charging position status acquisition unit obtains the occupancy status of each candidate charging position based on the vehicle arrival detection signal, the charging controller's operating status, the charging circuit occupancy status, and the station-side interlocking status:

[0106] Integrated management platform reading and , and The corresponding cross-line charging configuration record. Among them: The corresponding cross-line charging configuration record includes the task line identifier that allows the use of this charging position. And the charging position is enabled, therefore:

[0107] The corresponding cross-line charging configuration record includes the task line identifier that allows the use of this charging position. And the charging position is enabled, therefore:

[0108] The corresponding cross-line charging configuration record does not include the task line identifier that allows the use of this charging position. ,therefore:

[0109] This yields the set of valid charging positions:

[0110] Let the vehicle's current position be Candidate charging spots recorded in the target charging station's basic configuration record. and The reference stop coordinates are respectively and The positional deviation is calculated as follows:

[0111]

[0112] because Position deviation less than The positional deviation is such that the target charging position is determined as follows:

[0113] The integrated management platform is based on the target charging station Target charging position and the current mission route Query cross-line charging configuration records. There exists a cross-line charging configuration record that simultaneously meets the following conditions: The target charging station is marked as ; The charging position is marked as ; The task line identifier that allows the use of this charging position contains ; The charging position is enabled.

[0114] The target parking parameter record number in this cross-line charging configuration record is: The on-board charging control configuration number is The vehicle HMI interface number is The charging handshake parameter group number is .

[0115] Therefore, the integrated management platform reads:

[0116]

[0117]

[0118]

[0119] The vehicle control system returns the currently loaded on-board charging control configuration number:

[0120] because:

[0121] The integrated management platform generates the target configuration message. The configuration switching instruction field is then written to the target configuration message. The field content is as follows: Write the target charging station number field ; Write the target charging position number field ; Write the target stop parameter record number field ; Write the target on-board charging control configuration number field ; Vehicle HMI Interface Number Field Write ; Write the charging handshake parameter group number field ; The configuration switching command field needs to be written to indicate that a switch is required.

[0122] The integrated management platform will configure the target message. Simultaneously, the data is distributed to the vehicle control system and the vehicle HMI interface.

[0123] The vehicle control system based on the target configuration message Load target stop parameter record Target on-board charging control configuration and charging handshake parameter group .

[0124] The vehicle HMI interface is configured according to the target message. Switch to target charging station The corresponding page displays the target charging location. And lock onto the current mission route. Unsuitable candidate charging positions.

[0125] After the vehicle control system and vehicle HMI interface have completed configuration loading, the first vehicle readback message is returned.

[0126] If the on-board charging control configuration number returned by the on-board control system in the first on-board readback message is still [missing information], then [missing information]. If the field comparison results are inconsistent, the following judgment is made:

[0127] At this point, take:

[0128] It does not output the charging handshake enable state and returns to regenerate the target configuration message. The configuration switching instruction field still contains the field indicating that a switch is required.

[0129] After being reissued, the vehicle control system and the vehicle HMI interface returned a second vehicle readback message.

[0130] The fields in the second vehicle-mounted readback message are as follows: The record number of the loaded target parking position parameters returned by the vehicle control system is ; The on-board charging control configuration number returned by the vehicle control system is ; The number of the loaded charging handshake parameter group returned by the vehicle control system is ; The page number of the loaded target charging station returned by the vehicle HMI interface is: ; The target charging location number returned by the vehicle's HMI interface is ; The number of the loaded vehicle HMI interface returned by the vehicle HMI interface is .

[0131] The above fields and the target configuration message Since the corresponding fields match, the following conclusion is reached:

[0132] The station-side charging position status acquisition unit verifies the target charging position status. At this time:

[0133] Therefore, we take:

[0134] Outputs the charging handshake enable state, allowing the vehicle to enter the parking confirmation, pantograph raising, and charging handshake process.

[0135] Example 2: This embodiment illustrates the secondary matching process after the target charging position state changes.

[0136] Assume the vehicle's current mission route identifier remains:

[0137] The next target charging station identifier in the vehicle operation task record remains:

[0138] The set of candidate charging spots read from the target charging station's basic configuration record is as follows:

[0139] The initial occupancy status is:

[0140] Based on the cross-line charging configuration records, the compatibility relationship is determined as follows:

[0141] Therefore, the set of effective charging positions is:

[0142] The positional deviations between the vehicle's current location and the coordinates of the two valid charging position reference locations are as follows:

[0143]

[0144] The first target charging location is determined as follows:

[0145] Integrated management platform based on , and Query cross-line charging configuration records and generate the corresponding target configuration message.

[0146] After the target configuration message is sent and before the charging handshake enable status is output, the station-side charging position status acquisition unit refreshes the target charging position status and obtains:

[0147] Explanation of the first selected target charging position It is already in use.

[0148] Even if the vehicle readback message is consistent with the target configuration message at this time, that is:

[0149] Still because ,Pick:

[0150] No charging handshake enable state is output.

[0151] Target charging position Remove from the set of valid charging positions to obtain a new set of valid charging positions:

[0152] Re-determine the target charging location:

[0153] Integrated management platform based on , and Query cross-line charging configuration records; there exists a cross-line charging configuration record that meets the following conditions: The target charging station is marked as ; The charging position is marked as ; The task line identifier that allows the use of this charging position contains ; The charging position is enabled.

[0154] The target parking parameter record number in this cross-line charging configuration record is: The on-board charging control configuration number is The vehicle HMI interface number is The charging handshake parameter group number is .

[0155] The integrated management platform regenerates the target configuration message. In the new target configuration message, the target charging station number field is still written to... The target charging position number field is... Updated to The target stop parameter record number field is... Updated to The target on-board charging control configuration number field is... Updated to The vehicle HMI interface number field is... Updated to The charging handshake parameter group number field is... Updated to .

[0156] The new target configuration message is sent to the vehicle control system and the vehicle HMI interface.

[0157] The vehicle control system loads new target parking position parameter records. Target on-board charging control configuration and charging handshake parameter group .

[0158] Switching to vehicle HMI interface The corresponding page displays the target charging location. .

[0159] The vehicle control system and vehicle HMI interface return new vehicle readback messages.

[0160] When the target charging station number, target charging position number, target parking position parameter record number, target on-board charging control configuration number, on-board HMI interface number, and charging handshake parameter group number in the new on-board readback message are all consistent with those in the new target configuration message, it is determined that:

[0161] Second review:

[0162] Therefore, we take:

[0163] Outputs a charging handshake enable state, allowing the vehicle to enter the target charging location. The corresponding charging handshake process.

[0164] This embodiment illustrates that when the status of the target charging position changes after the configuration is issued, even if the configuration fields have been read back and found to be consistent, as long as the target charging position is no longer idle, the system will still prohibit the vehicle from entering the charging handshake process and perform a second matching of the charging position.

[0165] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
