Description

Technical Field

[0001] This application relates to the field of fuel cell vehicle refueling technology, specifically to a hydrogen swapping control method, device, equipment, and computer-readable storage medium. Background Technology

[0002] With the rapid development of the fuel cell vehicle industry, hydrogen swapping has become an important technological route in the hydrogen transportation field due to its advantages of fast refueling speed and high cylinder utilization. However, existing hydrogen swapping technologies have significant shortcomings in terms of operational efficiency and multi-entity collaboration, specifically: Current hydrogen swapping operations generally follow a sequential process of "vehicle arrival - disassembly of old hydrogen storage modules - screening and transfer of new modules - installation of new modules". The target hydrogen storage module can only be matched to specifications and transferred to the work station after the old modules have been completely removed, resulting in a significant waiting window.

[0003] In addition, existing technologies have a crude safety monitoring mechanism for hydrogen storage modules in non-vehicle storage scenarios: continuous online monitoring leads to excessive standby power consumption, making it difficult to guarantee backup power supply; low-frequency intermittent detection cannot identify risks such as hydrogen leakage and sudden pressure drop in a timely manner.

[0004] Therefore, there is an urgent need for a highly automated and coordinated hydrogen exchange control method to solve the technical problem of low efficiency in existing hydrogen exchange operations. Summary of the Invention

[0005] This application provides a hydrogen exchange control method, apparatus, equipment, and computer-readable storage medium, which can solve the technical problem of low efficiency in hydrogen exchange operations in the prior art.

[0006] In a first aspect, embodiments of this application provide a hydrogen exchange control method, including: Based on the distance information between the target vehicle and the hydrogen exchange station and the detection results of whether the target vehicle is currently in a safe state, the unloading control of the on-board hydrogen storage module is carried out, and the inventory data is updated according to the history information of the unloaded hydrogen storage module. Based on the distance information, the matching parameters of the on-board hydrogen storage module, and the current inventory data, the target hydrogen storage module is determined, and the installation of the target hydrogen storage module is controlled. For any hydrogen storage module in the inventory, the inventory data and the health detection frequency are updated based on the health detection results of the hydrogen storage module.

[0007] In conjunction with the first aspect, in one implementation, updating the inventory data and the health check frequency based on the health check results of the hydrogen storage module includes: If the current health test result is normal, the health test frequency is determined based on the storage time of the hydrogen module in the storage facility. If the result of the current health check is an alert, the alert information is uploaded, and the health check frequency is determined based on the content of the alert information and the preset alert level. If the current health check result is a fault, the hydrogen storage module will be isolated and an alarm message will be sent.

[0008] In conjunction with the first aspect, in one implementation, the current inventory data includes matching parameters and health status corresponding to each hydrogen storage module in the current inventory; determining the target hydrogen storage module based on the distance information, the matching parameters of the on-board hydrogen storage module, and the current inventory data includes: When the distance between the target vehicle and the hydrogen exchange station is less than or equal to the maximum identification distance of the hydrogen exchange station, the matching parameters of the on-board hydrogen storage module are sent. At least one schedulable hydrogen storage module is determined based on the health status of each hydrogen storage module in the inventory data. The target hydrogen storage module is determined from the schedulable hydrogen storage modules based on the matching parameters of the on-board hydrogen storage module and the matching parameters of the schedulable hydrogen storage module.

[0009] In conjunction with the first aspect, in one implementation, the unloading control of the on-board hydrogen storage module based on the distance information between the target vehicle and the hydrogen exchange station and the detection result of whether the target vehicle is currently in a safe state includes: If the distance between the target vehicle and the hydrogen exchange station is less than or equal to the maximum hydrogen exchange operation distance of the hydrogen exchange station, determine whether the target vehicle is simultaneously in the parking position and in the power-off state. If the target vehicle is simultaneously in park and powered off state, the on-board hydrogen storage module is unloaded. If the target vehicle is not simultaneously in the parking position and powered off state, a prompt message is sent, and the step of determining whether the target vehicle is simultaneously in the parking position and powered off state is re-executed.

[0010] In conjunction with the first aspect, in one embodiment, prior to the step of updating the inventory data based on the history information of the unloaded hydrogen storage module, the method further includes: The unloaded hydrogen storage module undergoes a pre-warehouse inspection process. If the result of the pre-warehousing inspection process is qualified, then the step of updating the inventory data based on the history information of the unloaded hydrogen storage module is executed. If the result of the pre-entry inspection process is unqualified, the unloaded hydrogen storage module will be isolated and an alarm message will be sent.

[0011] In conjunction with the first aspect, in one embodiment, prior to the step of controlling the installation of the target hydrogen storage module, the method further includes: If the pre-installation test result of the target hydrogen storage module is qualified, the step of controlling the installation of the target hydrogen storage module shall be performed. If the pre-installation test result of the target hydrogen storage module is unqualified, a backup hydrogen storage module is determined based on the target vehicle information and the current inventory data, and the backup hydrogen storage module is used as the target hydrogen storage module.

[0012] In conjunction with the first aspect, in one embodiment, unloading the on-board hydrogen storage module includes: Release the gas inside the pipeline of the target vehicle; If the pipeline pressure of the target vehicle is less than or equal to the safe pressure relief threshold, then disconnect the pipeline connection and mechanical fixing connection between the target vehicle and the on-board hydrogen storage module to complete the unloading. If the pressure in the target vehicle's pipeline is greater than the safe pressure relief threshold and the time taken to perform the step of releasing the gas in the target vehicle's pipeline is greater than or equal to the time threshold, an alarm will be triggered and reported to the system.

[0013] In conjunction with the first aspect, in one embodiment, the step of performing the installation control of the target hydrogen storage module includes: The target hydrogen storage module is installed at a designated location on the target vehicle, and a pipeline connection and mechanical fixation connection are established between the target vehicle and the target vehicle. If the pressure drop in the pipeline of the target vehicle is less than or equal to the pressure drop threshold, and the hydrogen purity in the pipeline is greater than or equal to the hydrogen purity threshold, then the installation of the target hydrogen storage module is determined to be complete. If the pressure drop in the pipeline of the target vehicle is less than or equal to the pressure drop threshold, and the hydrogen purity in the pipeline is less than the hydrogen purity threshold, then control the hydrogen in the target hydrogen storage module to enter the pipeline until the hydrogen purity in the pipeline is greater than or equal to the hydrogen purity threshold. If the pressure drop in the pipeline of the target vehicle exceeds the pressure drop threshold, an alarm message is sent and the installation process of the target hydrogen storage module is stopped.

[0014] Secondly, embodiments of this application provide a hydrogen exchange control device, comprising: The unloading module is used to control the unloading of the on-board hydrogen storage module based on the distance information between the target vehicle and the hydrogen exchange station and the detection result of whether the target vehicle is currently in a safe state. The matching module is used to determine the target hydrogen storage module based on the distance information, the matching parameters of the on-board hydrogen storage module, and the current inventory data; The installation module is used for installation control of the target hydrogen storage module; The inventory management module is used to update the inventory data based on the history information of the unloaded hydrogen storage modules; it is also used to update the inventory data and the health detection frequency for any hydrogen storage module in the inventory based on the health detection results of the hydrogen storage module.

[0015] In conjunction with the second aspect, in one implementation, the inventory management module is further configured to: If the current health test result is normal, the health test frequency is determined based on the storage time of the hydrogen module in the storage facility. If the result of the current health check is an alert, the alert information is uploaded, and the health check frequency is determined based on the content of the alert information and the preset alert level. If the current health check result is a fault, the hydrogen storage module will be isolated and an alarm message will be sent.

[0016] Thirdly, embodiments of this application provide a hydrogen exchange control device, including a processor, a memory, and a hydrogen exchange control program stored in the memory and executable by the processor, wherein when the hydrogen exchange control program is executed by the processor, it implements the steps of the hydrogen exchange control method as described in any one of the first aspects above.

[0017] Fourthly, embodiments of this application provide a computer-readable storage medium storing a hydrogen exchange control program, wherein when the hydrogen exchange control program is executed by a processor, it implements the steps of the hydrogen exchange control method as described in any one of the first aspects above.

[0018] The beneficial effects of the technical solutions provided in this application include: Based on the distance information between the target vehicle and the hydrogen exchange station, and the detection results of whether the target vehicle is currently in a safe state, the unloading control of the on-board hydrogen storage module is performed. The target hydrogen storage module is determined based on the distance information, the matching parameters of the on-board hydrogen storage module, and the current inventory data, and the installation control of the target hydrogen storage module is performed. This achieves parallel operation between the removal of the on-board hydrogen storage module and the selection of the target hydrogen storage module, ensuring that the target hydrogen storage module is in place when the vehicle stops, eliminating the waiting window period. This solves the technical problem in existing hydrogen exchange technologies where the sequential process results in long hydrogen exchange times for a single vehicle, limiting the overall vehicle turnover efficiency of the hydrogen exchange station. Furthermore, this application updates the inventory data and health detection frequency based on the health detection results of the stored hydrogen modules. This avoids excessive power consumption caused by continuous online detection of normal hydrogen storage modules, while increasing the detection frequency of low-health hydrogen storage modules. This solves the technical problem in existing technologies where the safety and reliability of non-vehicle-mounted hydrogen storage modules are difficult to balance with power consumption control.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0022] In one aspect, embodiments of this application provide a hydrogen exchange control method.

[0023] In one embodiment, reference is made to Figure 1 , Figure 1 This is a schematic flowchart of the first embodiment of the hydrogen exchange control method of this application. Figure 1 As shown, the hydrogen swapping control methods include: Step S1: Based on the distance information between the target vehicle and the hydrogen exchange station and the detection results of whether the target vehicle is currently in a safe state, the unloading control of the on-board hydrogen storage module is performed, and the inventory data is updated according to the history information of the unloaded hydrogen storage module. like Figure 2 As shown, the embodiment equipped with the solution of this application is an automated hydrogen swapping system for fuel cell vehicles, including the target vehicle, the hydrogen swapping station control system and the remote monitoring cloud platform. The three endpoints are connected to each other through wireless transmission to realize real-time data interaction between the three endpoints.

[0024] In this embodiment, the target vehicle is equipped with: The vehicle T-BOX is connected to the vehicle's VCU via CAN communication and wirelessly transmits information to the remote monitoring platform for interaction.

[0025] Vehicle VCU: It communicates with the vehicle T-BOX, hydrogen storage module control unit and engine controller FCU via CAN communication to achieve signal interaction and coordinate the work of various vehicle components.

[0026] Engine Controller (FCU): Used to adjust the output power of the fuel cell stack in real time.

[0027] Hydrogen storage module: Used to supply hydrogen to the fuel cell of the target vehicle; Hydrogen storage module control unit: Installed at the vehicle end. When hydrogen replacement is required, the replacement switch can be set to ON, and the vehicle is in hydrogen replacement mode. When the hydrogen replacement switch is OFF, the hydrogen replacement mode is exited.

[0028] The hydrogen storage module control unit includes: Valve assembly control unit: Used to receive control signals to control the gas path between the target vehicle and the hydrogen storage module.

[0029] Status acquisition unit: used to acquire the current status information of the hydrogen storage module.

[0030] Display unit: Used to display the status information of the hydrogen storage module (hydrogen storage capacity, pressure, etc.), and can also realize audible and visual alarms.

[0031] In this embodiment, the hydrogen storage module is a detachable module that can be installed on a fuel cell vehicle with a corresponding interface to achieve hydrogen supply in the vehicle state; it can also be hoisted and disassembled as needed to store hydrogen at the corresponding hydrogen exchange station to achieve filling, maintenance and storage in the off-vehicle state.

[0032] Specifically, as shown in Figure 3, the hydrogen storage module in this embodiment includes: The hydrogen storage cylinder group 5, used to store hydrogen, typically consists of multiple hydrogen storage cylinders. Each hydrogen storage cylinder in the group 5 is equipped with a corresponding cylinder valve 4. The inlet end of the cylinder valve 4 is connected to the outlet end of the hydrogen storage cylinder, and the cylinder valve 4 includes a manual valve 410, a temperature sensor 420, and an overpressure relief device 430, used to control the flow of hydrogen out of the cylinder, measure the temperature inside the cylinder, and perform safe emergency release of hydrogen. In this embodiment, the outlet gas paths of multiple cylinder valves 4 are connected and converged into a main path for the flow of hydrogen.

[0033] In this embodiment, the hydrogen storage module also includes a combination valve 3. One section of the combination valve 3 is connected to the main gas path composed of the valves at each bottle opening. It includes a first filter 310, a one-way valve 320, a second filter 330, a second pressure sensor 340, a throttle valve 350, and a solenoid valve 360. It is used to open or close according to control commands to control the inflow and outflow of hydrogen in the hydrogen storage module.

[0034] In this embodiment, the other end of the combination valve 3 is connected to both the filling branch and the output branch gas path. The filling branch includes a hydrogen filling port 1 and a first one-way valve 2, which are used to obtain hydrogen through the filling device. The output branch includes a pressure regulating valve 6, the inlet of which is connected to the gas path of the combination valve 3, which can adjust the target output pressure according to the working pressure requirements of the fuel cell engine. The outlet of the pressure regulating valve 6 is connected to the inlet of the hydrogen purity detection sensor 7, which is used to detect the concentration of hydrogen in the pipeline.

[0035] In this embodiment, the output branch also includes a hydrogen exchange quick-connect mechanism 9, which establishes a gas path connection with the outlet end of the hydrogen purity detection sensor 7. It includes a male end 910 and a female end 920, wherein the male end 910 is installed and fixed to the hydrogen storage module, and the female end 920 is always fixedly installed at the vehicle end. The connection or disconnection of the male end 910 and the female end 920 can be achieved by unlocking the hydrogen exchange quick-connect mechanism electrically controlled by the hydrogen storage module control unit 13, which is used to realize the gas path and communication connection between the target vehicle and the hydrogen storage module.

[0036] In one embodiment, a venting branch is provided between the pressure regulating valve 6 and the hydrogen purity detection sensor 7. The venting branch includes a venting valve 10, which in this embodiment is an electrically controlled venting valve. It is normally closed and can be opened according to control requirements to achieve rapid release of gas in the pipeline. The venting port 11 is the outlet of the gas released in the pipeline and can be connected to a gas recovery device to realize the recovery of emitted gas and improve emission safety.

[0037] In one embodiment, a detection branch is provided between the hydrogen purity detection sensor 7 and the hydrogen exchange quick-connect mechanism 9. The detection branch is equipped with a pressure gauge 8 for detecting the gas pressure in the pipeline.

[0038] In this embodiment, the hydrogen storage module also includes a hydrogen concentration sensor 12, used to detect the hydrogen concentration in the environment due to hydrogen leakage from the hydrogen storage system. The hydrogen storage module control unit 13 is electrically connected to all electrical components and can control the opening status of each solenoid valve and pressure regulating valve as needed, realizing full-process control of hydrogen exchange and offline monitoring in non-vehicle mode. The power module 14 is mainly used to supply power to the various electrical components of the hydrogen storage system in non-vehicle mode, enabling autonomous offline monitoring.

[0039] In this embodiment, preparations for hydrogen swapping are performed based on the distance between the target vehicle and the hydrogen swapping station. When the target vehicle arrives at the hydrogen swapping station and is ready, the on-board hydrogen storage module is disassembled, and the unloaded hydrogen storage module is put into storage based on its history information, and the inventory data is updated.

[0040] Specifically, in this embodiment, step S1 includes: Step S101: When the distance between the target vehicle and the hydrogen exchange station is less than or equal to the maximum hydrogen exchange operation distance of the hydrogen exchange station, determine whether the target vehicle is simultaneously in the parking position and in the power-off state. like Figure 4 As shown in this embodiment, after the target vehicle enters the hydrogen exchange station's identification range, it establishes a communication connection with the hydrogen exchange station's control system through the vehicle's T-BOX. The vehicle controller automatically activates the hydrogen exchange preparation mode and starts the vehicle's hydrogen exchange mode self-test process. When the target vehicle enters the hydrogen exchange station's hydrogen exchange operation identification range (i.e., the distance between the target vehicle and the hydrogen exchange station is less than or equal to the hydrogen exchange station's maximum hydrogen exchange operation distance), the vehicle's VCU automatically detects whether the vehicle is in a relatively safe state (parking gear / vehicle powered down).

[0041] It is understood that the identification range in this embodiment is determined based on the wireless transmission coverage of the hydrogen exchange station, that is, a circular area centered on the hydrogen exchange station and with the maximum identification distance (i.e., the maximum identification distance) of the hydrogen exchange station's wireless communication as the radius. Those skilled in the art can divide the identification range based on geography and the service radiation area corresponding to each hydrogen exchange station, and realize remote wireless transmission of data through a remote monitoring cloud platform.

[0042] In addition, in this embodiment, the hydrogen exchange operation identification range refers to the hydrogen exchange operation area of ​​the hydrogen exchange station. Within this area, the hydrogen exchange station can perform the unloading and replacement process of the on-board hydrogen storage module on the target vehicle. The target vehicle can use whether the vehicle enters the hydrogen exchange operation range as the trigger condition for the vehicle VCU to confirm whether the vehicle is in a relatively safe state. Those skilled in the art can set the start condition for the vehicle VCU to automatically detect whether the vehicle is in a relatively safe state according to their own needs.

[0043] Step S102: If the target vehicle is simultaneously in park and powered off state, unload the on-board hydrogen storage module; In this embodiment, when the vehicle's VCU detects that the target vehicle is simultaneously in the parking position and powered off (i.e., the vehicle is in a relatively safe state), it controls the target vehicle to enter the formal hydrogen swapping mode. The vehicle's VCU sends a pipeline depressurization command to the on-board hydrogen storage system control unit to release the gas in the target vehicle's pipeline. The hydrogen swapping control unit controls the combination valve 3 to close and the pressure regulating valve 6 and the vent valve 10 to release residual hydrogen from the vehicle-side connecting pipeline. At the same time, the pressure acquisition unit provides real-time feedback of pipeline pressure data. The vehicle's VCU compares the current pipeline pressure P with the safe depressurization threshold P1 to determine whether P ≤ P1. If the target vehicle's pipeline pressure P is less than or equal to the safe depressurization threshold P1, it is determined that the pipeline residual hydrogen release is complete. If the timeout is not met (i.e., the target vehicle's pipeline pressure is greater than the safe depressurization threshold and the time taken to execute the step of releasing the gas in the target vehicle's pipeline is greater than or equal to the time threshold), it is determined that the pipeline is abnormal, triggers an alarm and reports to the station control system, awaits manual handling, and performs a pressure check again.

[0044] When the vehicle's VCU determines that the residual hydrogen in the pipeline has been discharged, it issues an unlocking command to the hydrogen exchange quick-connect mechanism 9, disconnecting the pipeline connection and mechanical fixing connection between the on-board hydrogen storage module and the target vehicle, so that the male terminal 910 and the female terminal 920 are disconnected. The vehicle's VCU sends a signal to the hydrogen exchange station control system that the on-board hydrogen storage module can be removed, and the hydrogen exchange station's hydrogen exchange structure is removed from the on-board hydrogen storage module, completing the unloading.

[0045] It is understood that in this embodiment, the safe pressure relief threshold P1 is a judgment value for determining whether the pressure in the pipeline is safe. The specific value can be determined according to different hydrogen storage module specifications and the needs of those skilled in the art.

[0046] In addition, in this embodiment, the time threshold is a judgment value for whether the step of releasing the gas in the target vehicle pipe has exceeded the time limit. Those skilled in the art can determine the specific duration of the time threshold according to their own process requirements.

[0047] Step S103: If the target vehicle is not simultaneously in the parking position and in the power-off state, send a prompt message and re-execute the step of determining whether the target vehicle is simultaneously in the parking position and in the power-off state.

[0048] In this embodiment, if the target vehicle is within the hydrogen exchange station's identification range but is not in the park position or powered off (e.g., waiting for the vehicle in front to complete its hydrogen exchange), the hydrogen exchange station sends a prompt message to the target vehicle (e.g., "Please wait for the vehicle in front to complete" or "Please park and power off in the designated location"), and continuously monitors the target vehicle's status.

[0049] In one embodiment, the solution further includes: The unloaded hydrogen storage module undergoes a pre-warehouse inspection process. If the result of the pre-warehousing inspection process is qualified, then the step of updating the inventory data based on the history information of the unloaded hydrogen storage module is executed. If the result of the pre-entry inspection process is unqualified, the unloaded hydrogen storage module will be isolated and an alarm message will be sent.

[0050] In this embodiment, hydrogen is added to the unloaded hydrogen storage module. The adding equipment synchronizes data such as the filling amount, filling pressure, and filling sequence number to the hydrogen storage system control module 13 and executes the pre-entry inspection process, which detects the pressure, temperature, and valve airtightness inside the cylinder. The module's unique ID, filling information, cumulative filling times, and health status label are all uploaded to the remote monitoring cloud platform to complete the entry registration. After passing the self-inspection, the control module enters a deep sleep mode and sets the basic sleep duration t1. At the same time, the low-power real-time listening channel is activated to listen only to pre-scheduled instructions and emergency alarm instructions from the cloud, minimizing standby power consumption.

[0051] If the self-inspection result is unqualified, the hydrogen exchange mechanism will unload and move the hydrogen storage module away, and send an alarm message to notify personnel to investigate and handle the situation.

[0052] Step S2: Based on the distance information, the matching parameters of the on-board hydrogen storage module, and the current inventory data, determine the target hydrogen storage module and control its installation.

[0053] In this embodiment, before the target vehicle arrives at the hydrogen exchange station, a suitable target hydrogen storage module is matched with the one in stock based on the relevant parameters of the target vehicle's onboard hydrogen storage module. Installation is then performed when the installation conditions are met, thus achieving parallel unloading of the onboard hydrogen storage module and selection of the target hydrogen storage module. It should be noted that the matching parameters for the onboard hydrogen storage module include, but are not limited to, specifications and hydrogen exchange requirements, such as the specifications of the hydrogen storage cylinder group, the hydrogen storage capacity, and the rated operating pressure level—key matching conditions.

[0054] Specifically, in this embodiment, step S2 includes: Step S201: When the distance between the target vehicle and the hydrogen exchange station is less than or equal to the maximum identification distance of the hydrogen exchange station, send the matching parameters of the on-board hydrogen storage module; In this embodiment, when the target vehicle enters the hydrogen exchange station's identification range, the vehicle's T-BOX packages and uploads the specifications and parameters of the on-board hydrogen storage module and the hydrogen exchange requirements to the station control system.

[0055] Step S202: Based on the health status of each hydrogen storage module in the inventory data, determine at least one schedulable hydrogen storage module.

[0056] In this embodiment, after receiving the request, the hydrogen exchange station control system removes hydrogen storage modules whose health does not meet the requirements based on the inventory status of the hydrogen storage modules in the station, and confirms the hydrogen storage modules that can be scheduled.

[0057] Step S203: Determine the target hydrogen storage module from the schedulable hydrogen storage modules based on the matching parameters of the on-board hydrogen storage module and the matching parameters corresponding to the schedulable hydrogen storage modules.

[0058] In this embodiment, the hydrogen exchange station control system will also automatically filter target hydrogen storage modules that meet the specifications based on the specifications uploaded by the target vehicle and the hydrogen exchange requirements, generate matching results, and feed them back to the vehicle's VCU.

[0059] Step S204: If the pre-installation test result of the target hydrogen storage module is qualified, execute the step of controlling the installation of the target hydrogen storage module; like Figure 4 , Figure 5 As shown in this embodiment, the hydrogen exchange station control system sends a pre-schedule matching command to the target hydrogen storage module, controlling the target hydrogen storage module to wake up from hibernation and perform a high-standard self-check before hydrogen exchange, including hydrogen leak detection, pressure and temperature verification, valve function testing, and interface status confirmation. At the same time, all status parameters of the module are uploaded to the cloud in real time. After the self-check is passed, the module is marked as ready for hydrogen exchange and sends a "schedulable" signal to the cloud. The station control system then starts the module transfer, unloads the target hydrogen storage module into the designated location of the target vehicle, and establishes a pipeline connection and mechanical fixation connection with the target vehicle.

[0060] After mechanical fixing is completed, the hydrogen exchange control unit 13 of the target hydrogen storage module controls the locking quick-connect mechanism 9 to lock the male end 910 and the female end 920, and sends a signal to the vehicle indicating that the installation is in place. The target hydrogen storage module synchronizes its own status parameters (filling times, hydrogen storage capacity, pressure, temperature, etc.) to the vehicle's VCU and communicates with the fuel cell engine FCU, controlling the opening of the target hydrogen storage module's combination valve 3 and pressure regulating valve 6 to fill the pipeline with gas until the pipeline pressure in the target vehicle reaches the preset detection pressure; it then determines whether the pipeline pressure drop in the target vehicle meets △P≤△P1. If the pipeline pressure drop in the target vehicle △P>△P1, the installation process of the target hydrogen storage module is stopped and an alarm message is sent; if the pipeline pressure drop △P≤△P1 (i.e., the target vehicle...) is not satisfied, the installation process of the target hydrogen storage module is stopped. If the pressure drop in the pipeline is less than or equal to the pressure drop threshold, it is determined that the connection between the male terminal 910 and the female terminal 920 is reliable. The hydrogen purity K in the pipeline is detected by the hydrogen purity detection sensor 7 to determine whether the hydrogen concentration in the target vehicle's pipeline meets the requirement of K≥K1. If K≥K1 (i.e., the hydrogen purity in the target vehicle's pipeline is greater than or equal to the hydrogen purity threshold), it is determined that the hydrogen purity in the pipeline meets the requirements. If not (i.e., the hydrogen purity in the target vehicle's pipeline is less than the hydrogen purity threshold), the opening and closing of the combination valve 3 and the vent valve 10 are controlled to allow the hydrogen in the hydrogen storage cylinder group 5 to enter the pipeline and be released to purge the pipeline until the hydrogen purity in the pipeline is greater than or equal to the hydrogen purity threshold, thus completing the installation of the target hydrogen storage module.

[0061] After the target hydrogen storage module is installed in the vehicle, the vehicle's VCU sends a pressure adjustment command to the pressure regulating valve 6 of the target hydrogen storage module according to the rated operating parameters of the fuel cell engine, precisely adjusting the output pressure to the engine's target operating pressure to complete the gas supply preparation; the vehicle's VCU sends a hydrogen exchange completion signal to the station control system, and the vehicle simultaneously prompts that the hydrogen exchange is complete; after detecting that the hydrogen exchange meets the automatic exit conditions, the vehicle's VCU exits the hydrogen exchange mode and restores normal driving privileges.

[0062] It is understood that the pressure drop threshold in this embodiment is a threshold for judging whether the pipeline connection in the target vehicle is reliable. Those skilled in the art can set the pressure drop threshold according to their own process requirements. Similarly, in this embodiment, the hydrogen purity threshold is the threshold for judging whether the hydrogen concentration in the pipeline of the target vehicle meets the standard. When the hydrogen concentration in the pipeline does not meet the standard, it indicates that there are a large number of other gases in the pipeline. These gases will have a negative impact on the performance of the vehicle and the life of the fuel cell after entering the fuel cell. Those skilled in the art can set the specific value of the hydrogen purity threshold according to their own process requirements.

[0063] Step S205: If the pre-installation test result of the target hydrogen storage module is unqualified, a backup hydrogen storage module is determined based on the target vehicle information and the current inventory data, and the backup hydrogen storage module is used as the target hydrogen storage module.

[0064] In this embodiment, if the target hydrogen storage module fails the self-test, it is immediately reported to the cloud and automatically marked as unavailable. The station control system then switches to a backup hydrogen storage module from the available hydrogen storage modules, completing the replacement before the vehicle arrives at the station, thus avoiding affecting the overall hydrogen replacement schedule.

[0065] Step S3: For any hydrogen storage module in the inventory, update the inventory data and health detection frequency based on the health detection results of the hydrogen storage module.

[0066] In this embodiment, for newly unloaded hydrogen storage modules and hydrogen storage modules in the warehouse, when these hydrogen storage modules are in deep dormancy and have not received any instructions, the control module will automatically wake up after the set dormancy time t1 is reached, and perform full status detection: environmental hydrogen concentration, bottle pressure, bottle temperature, valve status self-check, and update the corresponding detection frequency according to the self-check results.

[0067] Specifically, in this embodiment, step S3 includes: If the current health test result is normal, the health test frequency is determined based on the storage time of the hydrogen module in the storage facility. If the result of the current health check is an alert, the alert information is uploaded, and the health check frequency is determined based on the content of the alert information and the preset alert level. If the current health check result is a fault, the hydrogen storage module will be isolated and an alarm message will be sent.

[0068] In this embodiment, the hydrogen exchange control module uploads the detection data to the cloud and performs a three-level judgment after comparing it with the threshold: If the pressure inside the hydrogen storage module is less than the pressure warning threshold, the temperature inside the hydrogen storage module is less than the temperature warning threshold, and the hydrogen concentration inside the hydrogen storage module is less than the concentration warning threshold, the health test result is normal. The health test frequency is determined based on the storage time of the hydrogen storage module. If the pressure inside the hydrogen storage module is greater than or equal to the pressure warning threshold and less than the pressure fault threshold, or the temperature inside the hydrogen storage module is greater than or equal to the temperature warning threshold and less than the temperature fault threshold, or the hydrogen concentration inside the hydrogen storage module is greater than or equal to the concentration warning threshold and less than the concentration fault threshold, the result of this health check is a warning, and the warning information is uploaded. The health check frequency is determined based on the content of the warning information (such as "pressure warning", "temperature warning", or "currently there are two parameters at risk") and the preset warning level. It should be noted that the mapping relationship between the warning information content, the warning level, and the health check frequency can be obtained through experimental calibration and is not limited here. For example, in one embodiment, when the warning content of the current health check of the hydrogen storage module is that the hydrogen storage module has a warning risk for one parameter, the health check frequency of the hydrogen storage module is determined as the first check frequency; or when the warning content of the current health check is that the hydrogen storage module has a warning risk for two parameters, the health check frequency of the hydrogen storage module is determined as the second check frequency. It can be understood that the different values ​​corresponding to each check frequency are used to distinguish different warning information corresponding to different check frequencies; those skilled in the art can also formulate different judgment strategies based on their own actual situation.

[0069] If the pressure inside the hydrogen storage module is greater than or equal to the pressure fault threshold, or the temperature inside the hydrogen storage module is greater than or equal to the temperature fault threshold, or the hydrogen concentration inside the hydrogen storage module is greater than or equal to the concentration fault threshold, the current health check result is a fault, the hydrogen storage module is isolated and an alarm message is sent.

[0070] It is understood that in this embodiment, the pressure warning threshold, pressure fault threshold, temperature warning threshold, temperature fault threshold, concentration warning threshold, and concentration fault threshold are all thresholds for judging whether the pressure, temperature, and hydrogen concentration in the hydrogen storage module are normal. The specific values ​​can be set according to the needs of those skilled in the art.

[0071] In this embodiment, once a vehicle enters the hydrogen exchange station's identification range, the vehicle controller uploads the hydrogen exchange request. The station control system simultaneously completes the specification matching and pre-operation scheduling of the target hydrogen storage module. This process is executed in parallel with the vehicle's hydrogen exchange self-inspection and pipeline release procedures, significantly shortening the total hydrogen exchange time for a single vehicle, improving the vehicle turnover capacity and operational throughput of the hydrogen exchange station, and solving the technical problem of significant waiting window periods in hydrogen exchange control in related technologies.

[0072] In addition, this embodiment ensures the complete release of residual hydrogen in the pipeline by determining a pressure threshold before hydrogen replacement. After replacement, it sequentially performs airtightness pressure testing, closed-loop hydrogen purity purging, and precise output pressure matching. The reliability of interface connections is assessed by quantifying pipeline pressure drop, and the hydrogen purity in the pipeline is ensured to meet standards through charge-discharge cycle purging. Finally, the rated operating pressure of the fuel cell engine is precisely matched. This avoids safety risks such as hydrogen leakage and insufficient hydrogen purity, ensuring the stable operation of the fuel cell system and the safety of the hydrogen replacement operation.

[0073] This embodiment also employs a hierarchical sleep control strategy based on dynamic detection results to periodically wake up and conduct detection. This reduces standby power consumption while ensuring safe detection coverage, extends the power supply cycle of the hydrogen storage modules in the inventory, and, combined with a pre-scheduling scheme, can complete fault diagnosis before the hydrogen storage modules are put into operation. This avoids interrupting the hydrogen replacement process when installing faulty hydrogen storage modules, further improving the reliability of the hydrogen replacement operation.

[0074] Finally, this embodiment achieves full-process data synchronization and archiving of hydrogen storage modules from filling and warehousing, inventory detection, scheduling and transfer to vehicle use by linking the hydrogen storage system control unit with the remote monitoring cloud platform. This enables full life-cycle traceability of the hydrogen storage modules, ensuring the accuracy of the hydrogen storage module filling count record and providing complete data support for the refined operation of hydrogen exchange stations and the full life-cycle management of hydrogen storage modules.

[0075] Secondly, embodiments of this application also provide a hydrogen exchange control device.

[0076] In one embodiment, reference is made to Figure 6 , Figure 6 This is a functional module diagram of an embodiment of the hydrogen exchange control device of this application. Figure 6 As shown, the hydrogen exchange control device includes: The unloading module is used to control the unloading of the on-board hydrogen storage module based on the distance information between the target vehicle and the hydrogen exchange station and the detection result of whether the target vehicle is currently in a safe state. The matching module is used to determine the target hydrogen storage module based on the distance information, the matching parameters of the on-board hydrogen storage module, and the current inventory data; The installation module is used for installation control of the target hydrogen storage module; The inventory management module is used to update the inventory data based on the history information of the unloaded hydrogen storage modules; it is also used to update the inventory data and the health detection frequency for any hydrogen storage module in the inventory based on the health detection results of the hydrogen storage module.

[0077] Furthermore, in one embodiment, the inventory management module is also used for: If the current health test result is normal, the health test frequency is determined based on the storage time of the hydrogen module in the storage facility. If the result of the current health check is an alert, the alert information is uploaded, and the health check frequency is determined based on the content of the alert information and the preset alert level. If the current health check result is a fault, the hydrogen storage module will be isolated and an alarm message will be sent.

[0078] Furthermore, in one embodiment, the unloading module is also used for: If the distance between the target vehicle and the hydrogen exchange station is less than or equal to the maximum hydrogen exchange operation distance of the hydrogen exchange station, determine whether the target vehicle is simultaneously in the parking position and in the power-off state. If the target vehicle is simultaneously in park and powered off state, the on-board hydrogen storage module is unloaded. If the target vehicle is not simultaneously in the parking position and powered off state, a prompt message is sent, and the step of determining whether the target vehicle is simultaneously in the parking position and powered off state is re-executed.

[0079] Furthermore, in one embodiment, the inventory management module is also used for: The unloaded hydrogen storage module undergoes a pre-warehouse inspection process. If the result of the pre-warehousing inspection process is qualified, then the step of updating the inventory data based on the history information of the unloaded hydrogen storage module is executed. If the result of the pre-entry inspection process is unqualified, the unloaded hydrogen storage module will be isolated and an alarm message will be sent.

[0080] Furthermore, in one embodiment, the matching module is also used for: If the pre-installation test result of the target hydrogen storage module is qualified, the step of controlling the installation of the target hydrogen storage module shall be performed. If the pre-installation test result of the target hydrogen storage module is unqualified, a backup hydrogen storage module is determined based on the target vehicle information and the current inventory data, and the backup hydrogen storage module is used as the target hydrogen storage module.

[0081] Furthermore, in one embodiment, the unloading module is also used for: Release the gas inside the pipeline of the target vehicle; If the pipeline pressure of the target vehicle is less than or equal to the safe pressure relief threshold, then disconnect the pipeline connection and mechanical fixing connection between the target vehicle and the on-board hydrogen storage module to complete the unloading. If the pressure in the target vehicle's pipeline is greater than the safe pressure relief threshold and the time taken to perform the step of releasing the gas in the target vehicle's pipeline is greater than or equal to the time threshold, an alarm will be triggered and reported to the system.

[0082] Furthermore, in one embodiment, the installation module is also used for: The target hydrogen storage module is installed at a designated location on the target vehicle, and a pipeline connection and mechanical fixation connection are established between the target vehicle and the target vehicle. If the pressure drop in the pipeline of the target vehicle is less than or equal to the pressure drop threshold, and the hydrogen purity in the pipeline is greater than or equal to the hydrogen purity threshold, then the installation of the target hydrogen storage module is determined to be complete. If the pressure drop in the pipeline of the target vehicle is less than or equal to the pressure drop threshold, and the hydrogen purity in the pipeline is less than the hydrogen purity threshold, then control the hydrogen in the target hydrogen storage module to enter the pipeline until the hydrogen purity in the pipeline is greater than or equal to the hydrogen purity threshold. If the pressure drop in the pipeline of the target vehicle exceeds the pressure drop threshold, an alarm message is sent and the installation process of the target hydrogen storage module is stopped.
