[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a hydrogen fuel tank replacement method, device, computer equipment and storage medium. Background Art

[0002] At present, there are more and more hydrogen fuel vehicles that use hydrogen (hydrogen fuel) as an energy source. Compared with gasoline or electric vehicles, hydrogen fuel vehicles have the advantages of low greenhouse gas emissions, short refueling time, and long cruising range.

[0003] Existing hydrogen fuel vehicles use the method of replacing hydrogen fuel tanks to achieve hydrogen fuel replenishment. However, when replacing hydrogen fuel tanks, it is easy for the hydrogen pipeline to not be completely shut off and the tank to be placed inaccurately, which may cause hydrogen leakage and explosion.

[0004] The above-mentioned prior art solutions have the following defects:

[0005] When replacing hydrogen fuel tanks, hydrogen leakage is prone to cause explosion, which has poor safety. Summary of the invention

[0006] In order to improve the safety when replacing a hydrogen fuel tank, the present application provides a hydrogen fuel tank replacement method, apparatus, computer equipment, and storage medium.

[0007] The above-mentioned invention objective of the present application is achieved through the following technical solutions:

[0008] A hydrogen fuel tank replacement method, the hydrogen fuel tank replacement method comprising:

[0009] Closing the hydrogen pipeline, obtaining the hydrogen pipeline pressure, and analyzing the hydrogen pipeline pressure to generate hydrogen pipeline status information;

[0010] Real-time monitoring of the hydrogen pipeline status information, and analysis of the hydrogen pipeline status information to generate a hydrogen fuel tank replacement signal, control the removal of the old hydrogen fuel tank, and install and calibrate the new hydrogen fuel tank;

[0011] A hydrogen pipeline opening signal is generated to control the soft start of the hydrogen pipeline.

[0012] By adopting the above technical scheme, by accurately monitoring the internal pressure of the hydrogen pipeline and generating the status information of the hydrogen pipeline in real time, it is possible to accurately judge whether the hydrogen pipeline is completely closed, thereby preventing hydrogen leakage caused by the hydrogen pipeline not being completely closed when the old fuel tank is disassembled, thereby improving the safety of hydrogen fuel tank replacement; the removal of the old hydrogen fuel tank and the installation and calibration of the new hydrogen fuel tank are completed by the hydrogen fuel tank replacement signal control device, which reduces the possibility of human operating errors and ensures the accuracy and reliability of the hydrogen fuel tank replacement process; by controlling the soft start of the hydrogen pipeline, the airflow pressure shock when the hydrogen pipeline is suddenly opened is avoided, the hydrogen pipeline is protected from damage, and the service life of the equipment is extended. At the same time, the hydrogen pipeline is slowly opened by soft start, which is convenient for further observation of whether there is hydrogen leakage during the opening process, further improving the safety of hydrogen fuel tank replacement.

[0013] In a preferred example, the present application may be further configured as follows: analyzing the hydrogen pipeline pressure to generate hydrogen pipeline status information specifically includes:

[0014] Setting a pipeline pressure safety threshold, and comparing the hydrogen pipeline pressure with the pipeline pressure safety threshold;

[0015] When the hydrogen pipeline pressure is lower than the pipeline pressure safety threshold, determining that the hydrogen pipeline state information is that the hydrogen pipeline is not completely closed;

[0016] When the hydrogen pipeline pressure is not lower than the pipeline pressure safety threshold, it is determined that the hydrogen pipeline state information is that the hydrogen pipeline is completely closed.

[0017] By adopting the above technical solution, by automatically comparing the hydrogen pipeline pressure with the set safety threshold, it is determined whether the hydrogen pipeline is completely closed, thereby preventing potential safety risks caused by incomplete discharge of hydrogen.

[0018] In a preferred example, the present application may be further configured as follows: the step of analyzing the hydrogen pipeline status information to generate a hydrogen fuel tank replacement signal specifically includes:

[0019] When the hydrogen pipeline state information indicates that the hydrogen pipeline is not completely closed, a pipeline closing signal is generated to control the hydrogen pipeline to complete closing;

[0020] When the hydrogen pipeline status information indicates that the hydrogen pipeline is completely closed, a hydrogen fuel tank replacement signal is generated, and the old hydrogen fuel tank is removed and a new hydrogen fuel tank is installed and calibrated according to the hydrogen fuel tank replacement signal.

[0021] By adopting the above technical scheme, a corresponding control signal is generated according to the status information of whether the hydrogen pipeline is completely closed. When the hydrogen pipeline is not completely closed, a pipeline closing signal is generated in time to further close the hydrogen pipeline to prevent gas leakage during the replacement process. When the hydrogen pipeline is completely closed, a hydrogen fuel tank replacement signal is automatically generated to control the equipment to unload the old hydrogen fuel tank and install and calibrate the new hydrogen fuel tank, thereby reducing the operation time and reducing the risk of hydrogen leakage due to human factors.

[0022] In a preferred example, the present application can be further configured as follows: the control of removing the old hydrogen fuel tank and installing and calibrating the new hydrogen fuel tank specifically includes:

[0023] Accurately locate the position of the old hydrogen fuel tank, and control the removal of the old hydrogen fuel tank according to the hydrogen fuel tank replacement signal and the position of the old hydrogen fuel tank;

[0024] After the old hydrogen fuel tank is completely disassembled, the new hydrogen fuel tank is installed according to the hydrogen fuel tank replacement signal and the position of the old hydrogen fuel tank, and the angle and position of the new fuel tank are adjusted. The new hydrogen fuel tank is installed after being tightly docked with the connector.

[0025] By adopting the above technical solution, the position of the old hydrogen fuel tank is located by precise control equipment, and the old tank is removed according to the generated hydrogen fuel tank replacement signal, ensuring the accuracy of the disassembly process. When installing the new hydrogen fuel tank, the new hydrogen fuel tank is also adjusted using precise position and angle to ensure that the new hydrogen fuel tank is perfectly connected to the connectors on the hydrogen fuel vehicle, thereby avoiding potential leakage caused by improper installation and improving safety and reliability when replacing hydrogen fuel tanks.

[0026] In a preferred example, the present application may be further configured as follows: the controlling of the soft start of the hydrogen pipeline specifically includes:

[0027] monitoring the hydrogen flow rate and pipeline pressure in the hydrogen pipeline in real time, and gradually increasing the hydrogen flow rate;

[0028] When the hydrogen flow rate reaches a preset hydrogen flow rate, stabilizing the hydrogen flow rate and monitoring the fluctuation of the pipeline pressure;

[0029] When the fluctuation is within the preset safety range, continue to gradually increase the hydrogen flow rate until the pipeline pressure is adjusted to the normal working state pipeline pressure, stop increasing the hydrogen flow rate and maintain the hydrogen flow rate stable;

[0030] If the fluctuation is outside the preset safety range, a hydrogen cut-off signal is generated to control the new hydrogen fuel tank to stop supplying hydrogen.

[0031] By adopting the above technical solution, the hydrogen flow rate and pipeline pressure are monitored in real time, and the hydrogen flow rate is gradually increased. This method of gradually increasing the flow rate can effectively avoid pipeline damage and safety accidents caused by sudden hydrogen shock, extend the service life of the equipment, and further judge whether there is a leak in the hydrogen pipeline by judging whether the fluctuation of the pipeline pressure is within a safe range. If there is no leakage, continue to increase the hydrogen flow rate until the pipeline pressure reaches the normal working pipeline pressure, and complete the installation of the new fuel tank. If there is a leak, stop the hydrogen supply immediately to prevent danger, thereby further improving the safety of hydrogen tank replacement.

[0032] In a preferred example, the present application may be further configured as follows: before the installation and calibration of the new hydrogen fuel tank, the application may further include:

[0033] Conducting a visual inspection and structural integrity assessment on the new hydrogen fuel tank to determine whether the new hydrogen fuel tank has any physical defects;

[0034] When it is determined that the new hydrogen fuel tank has physical defects, the installation of the new hydrogen fuel tank is prohibited and a hydrogen fuel tank defect alarm signal is sent to remind the staff to deal with and eliminate the risk in a timely manner;

[0035] When it is determined that the new hydrogen fuel tank has no physical defects, an installation correction step for the new hydrogen fuel tank is allowed.

[0036] By adopting the above technical solution, through the appearance inspection and structural integrity assessment of the new hydrogen fuel tank, the physical defects of the new hydrogen fuel tank can be identified in time to prevent the safety hazards caused by the defective tank. If the new hydrogen fuel tank is found to have defects, a defect alarm signal is generated to notify the staff in time to avoid the installation of unqualified hydrogen fuel tanks, thereby maintaining the safety of equipment and personnel. If the new hydrogen fuel tank passes the inspection, the system allows it to enter the installation and correction steps to ensure the safety of the new hydrogen fuel tank installation process.

[0041] The hydrogen pipeline soft start module is used to generate a hydrogen pipeline opening signal to control the soft start of the hydrogen pipeline.

[0042] By adopting the above technical scheme, by accurately monitoring the internal pressure of the hydrogen pipeline and generating the status information of the hydrogen pipeline in real time, it is possible to accurately judge whether the hydrogen pipeline is completely closed, thereby preventing hydrogen leakage caused by the hydrogen pipeline not being completely closed when the old fuel tank is disassembled, thereby improving the safety of hydrogen fuel tank replacement; the removal of the old hydrogen fuel tank and the installation and calibration of the new hydrogen fuel tank are completed by the hydrogen fuel tank replacement signal control device, which reduces the possibility of human operating errors and ensures the accuracy and reliability of the hydrogen fuel tank replacement process; by controlling the soft start of the hydrogen pipeline, the airflow pressure shock when the hydrogen pipeline is suddenly opened is avoided, the hydrogen pipeline is protected from damage, and the service life of the equipment is extended. At the same time, the hydrogen pipeline is slowly opened by soft start, which is convenient for further observation of whether there is hydrogen leakage during the opening process, further improving the safety of hydrogen fuel tank replacement.

[0048] 1. By automatically comparing the hydrogen pipeline pressure with the set safety threshold, it is determined whether the hydrogen pipeline is completely closed, thereby preventing potential safety risks caused by incomplete discharge of hydrogen. According to the status information of whether the hydrogen pipeline is completely closed, a corresponding control signal is generated. If the hydrogen pipeline is not completely closed, a pipeline closing signal is generated in time to further close the hydrogen to prevent gas leakage during the replacement process. By judging whether the fluctuation of the pipeline pressure is within the safe range, it is further determined whether there is a leak in the hydrogen pipeline. If there is no leak, the hydrogen flow rate continues to be increased until the pipeline pressure reaches the normal working pipeline pressure to complete the installation of the new fuel tank. If there is a leak, the hydrogen supply is stopped immediately to prevent danger. The position of the old hydrogen fuel tank is located by precise control equipment, and the hydrogen fuel tank is replaced according to the generated The old tank is removed by changing the signal, ensuring the accuracy of the disassembly process. When installing a new hydrogen fuel tank, the new hydrogen fuel tank is also adjusted with precise position and angle to ensure that the new hydrogen fuel tank is perfectly docked with the connectors on the hydrogen fuel vehicle, thereby avoiding potential leakage caused by improper installation. Before installing the new hydrogen fuel tank, the physical defects of the new hydrogen fuel tank can be identified in time by performing an appearance inspection and structural integrity assessment on the new hydrogen fuel tank to prevent safety hazards caused by defective tanks. If defects are found in the new hydrogen fuel tank, a defect alarm signal is generated to notify the staff in time to handle it, avoiding the installation of unqualified hydrogen fuel tanks, thereby maintaining the safety of equipment and personnel. If the new hydrogen fuel tank passes the inspection, the system allows it to enter the installation and correction steps to ensure the safety of the new hydrogen fuel tank installation process and improve the safety of hydrogen tank replacement.

[0059] The present application is further described in detail below in conjunction with the accompanying drawings.

[0060] In one embodiment, if Figure 1 As shown, the present application discloses a method for replacing a hydrogen fuel tank, which specifically includes the following steps:

[0061] S10: closing the hydrogen pipeline, obtaining the hydrogen pipeline pressure, and analyzing the hydrogen pipeline pressure to generate hydrogen pipeline status information.

[0062] In this embodiment, the hydrogen pipeline pressure refers to the gas pressure inside the hydrogen pipeline; the hydrogen pipeline status information refers to status information of whether the hydrogen pipeline is completely closed.

[0063] Specifically, the hydrogen pipeline is closed, and the hydrogen pipeline pressure, that is, the gas pressure inside the hydrogen pipeline, is obtained through a gas pressure sensor in the hydrogen pipeline. The hydrogen pipeline pressure is compared and analyzed to obtain hydrogen pipeline status information representing whether the hydrogen pipeline is completely closed, thereby preventing hydrogen leakage caused by incomplete closure of the hydrogen pipeline when dismantling the old fuel tank.

[0064] S20: monitor the status information of the hydrogen pipeline in real time, analyze the status information of the hydrogen pipeline to generate a hydrogen fuel tank replacement signal, control the removal of the old hydrogen fuel tank, and install and calibrate the new hydrogen fuel tank.

[0065] In this embodiment, the hydrogen fuel tank replacement signal is used to control the device to replace the old hydrogen fuel tank on the hydrogen fuel vehicle with a new hydrogen fuel tank.

[0066] Specifically, the hydrogen pipeline status information is monitored and analyzed in real time. When the hydrogen pipeline status information shows that the hydrogen pipeline has been completely closed, a hydrogen fuel tank replacement signal is generated, and the control equipment completes the removal of the old hydrogen fuel tank and the installation and calibration of the new hydrogen fuel tank, reducing the possibility of human operating errors and ensuring the accuracy of the installation of the new hydrogen fuel tank.

[0067] S30: Generate a hydrogen pipeline opening signal to control the soft start of the hydrogen pipeline.

[0068] In this embodiment, the hydrogen pipeline opening signal refers to a signal for controlling the opening of a valve of the hydrogen pipeline to allow gas to flow inside; soft start refers to a start-up method of gradually increasing the hydrogen flow rate of the hydrogen pipeline.

[0069] Specifically, a hydrogen pipeline opening signal is generated to control the hydrogen pipeline to open gradually, gradually increase the hydrogen flow rate in the pipeline, avoid sudden opening of the hydrogen pipeline causing airflow pressure shock, protect the hydrogen pipeline from damage, and facilitate further observation of whether there is hydrogen leakage during the opening process.

[0070] In one embodiment, if Figure 2 As shown, in step S10, the hydrogen pipeline pressure is analyzed to generate hydrogen pipeline status information, which specifically includes:

[0071] S11: Set a pipeline pressure safety threshold, and compare the hydrogen pipeline pressure with the pipeline pressure safety threshold.

[0072] In this embodiment, the pipeline pressure safety threshold refers to the minimum value of the pipeline pressure when no leakage occurs in the hydrogen pipeline.

[0073] Specifically, the minimum value of the pipeline pressure without leakage in the hydrogen pipeline is obtained, that is, the pressure safety threshold, such as 1.9 kPa / cm 2 , compare the actual hydrogen pipeline pressure with the pipeline pressure safety threshold.

[0074] S12: When the hydrogen pipeline pressure is lower than the pipeline pressure safety threshold, it is determined that the hydrogen pipeline status information is that the hydrogen pipeline is not completely closed.

[0075] Specifically, when the hydrogen pipeline pressure is lower than the pipeline pressure safety threshold, such as the actual hydrogen pipeline pressure is "1kPa / cm 2 ", it is determined that the hydrogen pipeline is not completely closed, and the hydrogen pipeline status information is set to hydrogen pipeline is not completely closed.

[0076] S13: When the hydrogen pipeline pressure is not lower than the pipeline pressure safety threshold, the hydrogen pipeline status information is determined to be that the hydrogen pipeline is completely closed.

[0077] Specifically, when the hydrogen pipeline pressure is not lower than the pipeline pressure safety threshold, such as the actual hydrogen pipeline pressure is "2kPa / cm 2 ", it is determined that the hydrogen pipeline has been completely closed, and the hydrogen pipeline status information is set to hydrogen pipeline completely closed.

[0078] In one embodiment, if Figure 3 As shown, in step S20, the hydrogen pipeline status information is analyzed to generate a hydrogen fuel tank replacement signal, which specifically includes:

[0079] S21: When the hydrogen pipeline status information indicates that the hydrogen pipeline is not completely closed, a pipeline closing signal is generated to control the hydrogen pipeline to complete closing.

[0080] In this embodiment, the pipeline closing signal refers to a signal for closing a vent valve in a hydrogen pipeline.

[0081] Specifically, when the hydrogen pipeline status information indicates that the hydrogen pipeline is not completely closed, that is, when the hydrogen pipeline is not completely closed, a pipeline closing signal is generated in time, and the control device further closes the vent valve of the hydrogen pipeline to prevent gas leakage during the replacement process.

[0082] S22: When the hydrogen pipeline status information indicates that the hydrogen pipeline is completely closed, a hydrogen fuel tank replacement signal is generated, and the old hydrogen fuel tank is removed and a new hydrogen fuel tank is installed and calibrated according to the hydrogen fuel tank replacement signal.

[0083] Specifically, when the hydrogen pipeline is completely closed, a hydrogen fuel tank replacement signal is generated, the control equipment accurately removes the old hydrogen fuel tank, installs the new hydrogen fuel tank after the old hydrogen fuel tank is unloaded, and corrects the position and angle of the new hydrogen fuel tank to ensure that the new hydrogen fuel tank is tightly connected to the hydrogen pipeline.

[0084] In one embodiment, if Figure 4 As shown, in step S22, the old hydrogen fuel tank is removed and the new hydrogen fuel tank is installed and calibrated, which specifically includes:

[0085] S221: Accurately locate the position of the old hydrogen fuel tank, and control the removal of the old hydrogen fuel tank according to the hydrogen fuel tank replacement signal and the position of the old hydrogen fuel tank.

[0086] Specifically, sensors and cameras are used to accurately identify the location of the old hydrogen fuel tank, and the robotic arm is directed to grab the old hydrogen fuel tank according to its specific location and disassemble it, contacting the connection between the old hydrogen fuel tank and the vehicle.

[0087] S222: After the old hydrogen fuel tank is disassembled, install the new hydrogen fuel tank according to the hydrogen fuel tank replacement signal and the position of the old hydrogen fuel tank, adjust the angle and position of the new fuel tank, and complete the installation after the new hydrogen fuel tank is tightly connected to the connector.

[0088] Specifically, after the old hydrogen fuel tank is disassembled, the robotic arm is controlled to grab the new hydrogen fuel tank on the loading rack according to the hydrogen fuel tank replacement signal, and the new hydrogen fuel tank is installed and adjusted in position according to the position of the old hydrogen fuel tank. Finally, based on the feedback from the sensor and camera, the position and angle of the new hydrogen fuel tank are further fine-tuned to ensure that the new hydrogen fuel tank is tightly connected to the hydrogen pipeline.

[0089] In one embodiment, if Figure 5 As shown, in step S30, the soft start of the hydrogen pipeline is controlled, which specifically includes:

[0090] S31: monitor the hydrogen flow rate and pipeline pressure in the hydrogen pipeline in real time, and gradually increase the hydrogen flow rate.

[0091] In this embodiment, the hydrogen flow rate refers to the gas flow rate of hydrogen in the hydrogen pipeline; the pipeline pressure refers to the gas pressure in the hydrogen pipeline.

[0092] Specifically, an air flow meter is used to monitor the hydrogen flow rate in the hydrogen pipeline in real time, and a gas pressure sensor is used to monitor the gas pressure in the hydrogen pipeline, that is, the pipeline pressure, in real time, and the changes in the pipeline pressure are recorded. At the same time, the hydrogen flow rate inside the pipeline is gradually increased to avoid damage to the hydrogen pipeline due to sudden impact of hydrogen.

[0093] S32: When the hydrogen flow rate reaches the preset hydrogen flow rate, stabilize the hydrogen flow rate and monitor the fluctuation of the pipeline pressure.

[0094] In this embodiment, the preset hydrogen flow rate is set to 50% of the hydrogen flow rate inside the hydrogen pipeline under normal working conditions.

[0095] Specifically, the hydrogen flow rate is compared with the preset hydrogen flow rate. When the gradually increasing hydrogen flow rate reaches the preset hydrogen flow rate, that is, 50% of the hydrogen flow rate inside the hydrogen pipeline under normal working conditions, such as "0.02L / s", the hydrogen flow rate is stopped from being increased to keep the hydrogen flow rate stable, and then the fluctuation of the pipeline pressure is monitored.

[0096] S33: When the fluctuation is within the preset safety range, continue to gradually increase the hydrogen flow rate until the pipeline pressure is adjusted to the normal working state pipeline pressure, stop increasing the hydrogen flow rate and maintain the hydrogen flow rate stable.

[0097] In this embodiment, the safety range refers to the normal fluctuation range of the pipeline pressure when no leakage occurs in the hydrogen pipeline; the working state pipeline pressure refers to the gas pressure inside the pipeline when the hydrogen pipeline is in a normally connected working state.

[0098] Specifically, when the pipeline pressure fluctuation is within the preset safety range such as "±0.1kPa / cm 2", if the pipeline pressure fluctuation is "±00.5kPa / cm 2 ", it can be judged that the hydrogen pipeline is tightly connected to the new hydrogen fuel tank, there is no leakage, and there is no safety risk. Continue to gradually increase the hydrogen flow rate until the pipeline pressure rises to the normal working pressure. At this time, the hydrogen pipeline is already in normal working condition. Stop increasing the hydrogen flow rate and keep the hydrogen flow rate stable.

[0099] S34: If the fluctuation is outside the preset safety range, a hydrogen cut-off signal is generated to control the new hydrogen fuel tank to stop supplying hydrogen.

[0100] In this embodiment, the hydrogen cut-off signal refers to a signal for controlling the hydrogen fuel tank to close the communication valve.

[0101] Specifically, when the pipeline pressure fluctuation is within the preset safety range such as "±0.1kPa / cm 2 ", if the pipeline pressure fluctuation is "±0.2kPa / cm 2 ”, it can be judged that the hydrogen pipeline is not tightly connected to the new hydrogen fuel tank, hydrogen leakage is occurring, and there is a safety risk. A hydrogen cut-off signal is generated to control the new hydrogen fuel tank to close the connecting valve, stop the hydrogen supply, and prevent danger.

[0102] In one embodiment, if Figure 6 As shown, before installing and calibrating a new hydrogen fuel tank, it also includes:

[0103] S40: Conduct visual inspection and structural integrity assessment on new hydrogen fuel tanks to determine whether there are any physical defects in the new hydrogen fuel tanks.

[0104] In this embodiment, the physical defects refer to physical defects such as deformation and defect.

[0105] Specifically, the camera is used to obtain appearance images of the new hydrogen fuel tank from various angles and compare them with appearance images of normal hydrogen fuel tanks to evaluate whether the structure of the new hydrogen fuel tank is complete and whether the new hydrogen fuel tank is a defective tank.

[0106] S50: When it is determined that a new hydrogen fuel tank has physical defects, it is prohibited to install a new hydrogen fuel tank and a hydrogen fuel tank defect alarm signal is sent to remind the staff to deal with it in time to eliminate the risk.

[0107] Specifically, when it is determined that a new hydrogen fuel tank has physical defects, such as damage or verification of bumps, the installation of the new hydrogen fuel tank is prohibited, and a hydrogen fuel tank defect alarm signal is sent to the staff to remind them to conduct timely inspections and corresponding processing to prevent leakage of the new hydrogen fuel tank due to physical defects.

[0108] S60: When it is determined that the new hydrogen fuel tank has no physical defects, an installation correction step for the new hydrogen fuel tank is allowed.

[0109] Specifically, when it is determined that the new hydrogen fuel tank has no physical defects, that is, the new hydrogen fuel tank has a complete structure and no defects in appearance, subsequent installation and correction of the new hydrogen fuel tank is allowed to ensure the physical integrity of the new hydrogen fuel tank and ensure the safety of the installation process of the new hydrogen fuel tank.

[0110] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
