[0005] Furthermore, the method also includes: the controller obtains contact status information detected by a gun detachment detection module on the gas filling gun head of the hydrogen filling machine; if the gas filling gun head is detached from the pipe mouth of the high-pressure gas storage cylinder, the gas filling is stopped and the alarm device is activated to issue an alarm prompt.

[0006] Furthermore, the method also includes: recording gas filling process information through a station control computer, the gas filling process information including account, gas filling time, gas filling volume, gas filling fee, and temperature and pressure of the high-pressure gas cylinder during gas filling.

[0007] During the above implementation process, the station control computer can record the refueling process information of each refueling process, including account, refueling time, refueling volume, refueling fee, temperature and pressure of high-pressure gas cylinders during refueling, etc., which can provide data support for subsequent data analysis.

[0008] Furthermore, the method further includes: the cloud server analyzing the optimal refueling solution for the high-pressure gas storage cylinder based on the refueling process information of the hydrogen refueling vehicle at each hydrogen refueling station.

[0009] During the above implementation process, the cloud server can also analyze the optimal refueling plan for high-pressure gas cylinders based on the refueling process information of hydrogen-refueling vehicles at various hydrogen refueling stations, making hydrogen filling safer and more convenient.

[0010] In the second aspect, the present application provides an AI-assisted hydrogen filling management and control system, including a hydrogen filling machine; a cloud server connected to the hydrogen filling machine; a hydrogen filling vehicle connected to the hydrogen filling machine; the hydrogen filling machine includes a controller; a fingerprint acquisition module connected to the controller; a face acquisition module connected to the controller; a first infrared communication module connected to the controller; a flow meter connected to the controller; the hydrogen filling vehicle includes an on-board controller; a temperature sensor and a pressure sensor connected to the on-board controller; a second infrared communication module connected to the on-board controller; the temperature sensor and the pressure sensor are arranged on the high-pressure gas cylinder of the hydrogen filling vehicle; the cloud server is used to obtain the face The user face image collected by the acquisition module and the user fingerprint collected by the fingerprint acquisition module are analyzed to see whether the user face image matches the user fingerprint; if the user face image matches the user fingerprint, a refueling start instruction is sent to the hydrogenator; the hydrogenator refuels the high-pressure gas cylinder according to the refueling start instruction; the on-board controller is used to obtain the data information collected by the temperature sensor and the pressure sensor and send it to the controller through the second infrared communication module and the first infrared communication module; the controller is also used to adjust the refueling parameters according to the data information; the cloud server is also used to deduct the corresponding fee from the user's account according to the refueling amount at the end of refueling.

[0011] In the above implementation process, when gas is needed, the user first accurately connects the gas gun head of the gas filling machine with the nozzle of the high-pressure gas cylinder, and then collects the user's facial image through the facial acquisition module. The controller sends the facial image to the cloud server.

[0013] During the above implementation process, rapid filling will cause the temperature of the high-pressure gas cylinder to rise rapidly. Long-term, repeated filling will cause thermal fatigue of the metal material, which may easily cause the gun to fall out. Therefore, a gun-out detection module connected to the controller is also provided on the gas filling nozzle of the gas dispenser. When the gun-out detection module detects that the gas filling nozzle has separated from the nozzle of the high-pressure gas cylinder, gas filling will be stopped.

[0014] Furthermore, the hydrogenator also includes an alarm device connected to the controller, and the controller is further configured to activate the alarm device to issue an alarm prompt when the temperature and pressure of the high-pressure gas storage cylinder are abnormal.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0023] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0024] Please see Figure 1 , Figure 1 A schematic flow chart of a hydrogen filling control method provided in an embodiment of the present application.

[0025] In order to improve the safety of the hydrogen filling process and make the filling process more convenient and quick, the embodiment of the present application also provides a hydrogen filling management and control method, the specific content of which is as follows.

[0026] Step S101: Acquire a user's facial image, and retrieve corresponding account information based on the user's facial image.

[0027] When refueling with hydrogen, the user first accurately connects the refueling gun head of the hydrogen refueling machine with the nozzle of the high-pressure gas cylinder on the hydrogen refueling vehicle, and then faces the camera of the face acquisition module to capture the user's facial image. The controller obtains the facial image and sends it to the cloud server. The cloud server analyzes the facial image and retrieves the account information corresponding to the facial image from the database. The account includes the user's (driver's) basic identity information, the type of vehicle driven, the license plate number, the model of the high-pressure gas cylinder, the account balance, etc.

[0028] Step S102: obtaining a user fingerprint and analyzing whether the user fingerprint matches the user face image; if the user fingerprint matches the user face image, sending a refueling start instruction to a controller of the hydrogen filling machine.

[0029] After the cloud server retrieves the account information corresponding to the user's facial image, it sends it to the hydrogen filling machine and the station control computer. The user confirms whether his or her account information is correct on the hydrogen filling machine. If it is correct, the fingerprint collection module can be used to collect the user's fingerprint. The controller obtains the user's fingerprint and sends it to the cloud server; the cloud server analyzes whether the user's fingerprint matches the fingerprint recorded in the database. If the user's fingerprint matches the user's facial image, the cloud server directly sends a refueling start instruction to the controller of the hydrogen filling machine.

[0030] It should be noted that the cloud server may also first send an authorization instruction to the station control computer, and after the station control computer receives the authorization instruction, it will send a refueling start instruction to the hydrogen filling machine.

[0031] In step S103 , the controller fills the high-pressure gas cylinder of the hydrogen refueling vehicle with gas according to the gas filling start instruction.

[0032] When the hydrogen refueling machine controller receives the refueling start command, it opens the corresponding regulating valve to refuel the high-pressure gas cylinder of the hydrogen refueling vehicle. To more accurately control the flow rate of hydrogen, the regulating valve can be a proportional regulating valve.

[0033] In step S104, the vehicle-mounted controller obtains data information detected by the temperature sensor and the pressure sensor provided on the high-pressure gas cylinder during the refueling process, and sends the data information to the controller via the second infrared communication module and the first infrared communication module.

[0034] After refueling begins, the on-board controller will obtain the data information detected by the temperature sensor and pressure sensor installed on the high-pressure gas cylinder during the refueling process, and then send the data information to the controller through the second infrared communication module and the first infrared communication module, realizing real-time communication between the hydrogen filling machine controller and the high-pressure gas cylinder.

[0035] In step S105 , the controller adjusts the gas filling parameters according to the data information, stops the gas filling when the pressure of the high-pressure gas storage cylinder reaches a preset value, and analyzes the gas filling amount.

[0036] After receiving the temperature, pressure and other parameters of the high-pressure gas cylinder, the controller can adjust the gas filling parameters, stop gas filling when the pressure of the high-pressure gas cylinder reaches a preset value, and analyze the gas filling amount. Specifically, if the temperature of the high-pressure gas cylinder rises too quickly during the gas filling process (the temperature rise rate can be set according to the parameters of various types of gas cylinders), the gas filling speed and flow rate are reduced. During the gas filling process, a pressure threshold can also be set (for example, 80% of the upper limit pressure of the high-pressure gas cylinder). When the pressure of the high-pressure gas cylinder reaches this threshold, the regulating valve of the hydrogenator will be adjusted to halve the air flow rate and flow rate, and then continue to fill the high-pressure gas cylinder. When the pressure of the high-pressure gas cylinder reaches the preset value, the gas filling is stopped, and then the corresponding gas filling amount is obtained according to the pipeline flow detected by the flowmeter. In this way, the hydrogenator can adjust the gas filling parameters in real time according to the operating parameters of the high-pressure gas cylinder, and the gas filling process is safer and more reliable.

[0037] Step S106: When the gas filling is completed, the cloud server deducts the corresponding fee from the user's account according to the gas filling amount.

[0038] When the pressure of the high-pressure gas cylinder reaches the set upper limit pressure, the hydrogen filling machine stops filling, and the user can drive away after placing the gas filling gun head in the specified position; at the same time, the cloud server can calculate the cost of this filling based on the gas volume detected by the flow meter and the corresponding rate, and then deduct the corresponding fee from the account balance.

[0039] Rapid filling will cause the temperature of the gas cylinder to rise rapidly, and long-term, repeated filling will cause thermal fatigue of the metal material, which is prone to dangers such as gun detachment. Therefore, a gun detachment detection module can also be set on the gas filling gun head of the hydrogen filling machine. The controller can also obtain the contact status information detected by the gun detachment detection module on the gas filling gun head of the hydrogen filling machine; if the gas filling gun head is separated from the pipe mouth of the high-pressure gas storage cylinder, the gas filling will be stopped and the alarm device will be activated to issue an alarm prompt.

[0040] During the refueling process, the station control computer can also record refueling process information, such as account number, refueling time, refueling volume, refueling fee, and the temperature and pressure of the high-pressure gas cylinder during refueling, providing data support for later data analysis. For safer and more convenient refueling, cloud servers can also be used to analyze the historical refueling process information of hydrogen vehicles at various hydrogen refueling stations to provide the optimal refueling plan for the high-pressure gas storage cylinder of the hydrogen vehicle.

[0041] During refueling, the station's surveillance cameras can also capture image information near the dispenser, and then the station control computer or controller can identify the captured images to analyze whether there are any abnormal conditions near the dispenser during the refueling process. For example, the surveillance images near the dispenser can be identified to analyze whether anyone is smoking near the dispenser. If so, the alarm device will be activated to issue an alarm prompt. The surveillance images near the dispenser can also be identified to analyze whether the operator's operations during the refueling process comply with the regulations. If the operator's operations during the refueling process do not comply with the regulations, the alarm device will be activated to issue an alarm prompt.

[0042] Please see Figure 2 , Figure 2 A schematic diagram of the topological structure of a hydrogen filling control system provided in an embodiment of the present application.

[0043] The hydrogen filling control system 10 provided in the embodiment of the present application includes a hydrogen filling machine 100; a cloud server 300 connected to the hydrogen filling machine 100; a hydrogen filling vehicle connected to the hydrogen filling machine 100; the hydrogen filling machine 100 includes a controller 110; a fingerprint collection module 120 connected to the controller 110; a face collection module 130 connected to the controller 110; a first infrared communication module 140 connected to the controller 110; the hydrogen filling vehicle includes an on-board controller 210; a temperature sensor 221, a pressure sensor 222 and a flow meter 170 connected to the on-board controller 210; a second infrared communication module 230 connected to the on-board controller 210; the temperature sensor 221, the pressure sensor 222 and the flow meter 170 are arranged on the high pressure of the hydrogen filling vehicle On the gas cylinder 220; the cloud server 300 is used to obtain the user's facial image collected by the face collection module 130 and the user's fingerprint collected by the fingerprint collection module 120, and analyze whether the user's facial image and the user's fingerprint match; if the user's facial image and the user's fingerprint match, a refueling start instruction is sent to the hydrogenation machine 100; the hydrogenation machine 100 refuels the high-pressure gas cylinder 220 according to the refueling start instruction; the on-board controller 210 is used to obtain the data information collected by the temperature sensor 221 and the pressure sensor 222 respectively and send it to the controller 110 through the second infrared communication module 230 and the first infrared communication module 140; the flow meter 170 set on the hydrogenation machine 100 detects the pipeline flow during the hydrogenation process and sends it to the controller 110. The controller 110 is also used to adjust the refueling parameters according to the above data information; the cloud server 300 is also used to deduct the corresponding fee from the user's account according to the amount of gas added at the end of refueling.

[0044] When refueling, the user first accurately connects the refueling gun head of the hydrogen filling machine 100 with the nozzle of the high-pressure gas storage cylinder 220 of the hydrogen filling vehicle 200, and then aligns the face with the face acquisition module 130. The face acquisition module 130 acquires the user's facial image, and the controller 110 sends the facial image to the cloud server 300. The cloud server 300 retrieves the corresponding account information based on the facial image and sends it to the controller 110, and then displays it on the display of the gas filling machine. After the user confirms the account information, the fingerprint acquisition module 120 can be used to collect the user's fingerprint information. The cloud server 300 then analyzes the user's fingerprint and the user's facial image. If the two match, the cloud server 300 sends a refueling start instruction to the controller 110 to authorize hydrogenation. During refueling, the temperature sensor 221 and the pressure sensor 222 on the high-pressure gas cylinder 220 of the hydrogen refueling vehicle 200 will collect information such as the temperature and pressure of the high-pressure gas cylinder 220 in real time, and send it to the controller 110 through the second infrared communication module 230 and the first infrared communication module 140. The flow meter 170 set on the hydrogen refueling machine 100 can detect the pipeline flow during the hydrogenation process and send it to the controller 110; the controller 110 dynamically adjusts the refueling parameters according to information such as the temperature and pressure of the high-pressure gas cylinder 220 and the pipeline flow of the hydrogen refueling machine 100, making the refueling process safer and more reliable; at the same time, at the end of refueling, the cloud server 300 can also automatically deduct the corresponding fees from the user's account according to the amount of gas added (pipeline flow), which is more convenient and quick.

[0045] In one implementation, users can register at various hydrogen refueling stations with their vehicle registration, driver's license, and ID card. These information is entered into the station's control computer 400 and then uploaded to the cloud server 300. During registration, the user's facial information serves as the account number, and their fingerprint serves as the password. After registration, users can pre-fund their account using WeChat, Alipay, or a bank card. When a hydrogen refueling vehicle arrives at a hydrogen refueling station, the user accurately aligns the refueling nozzle of the hydrogen refueling machine 100 with the nozzle of the high-pressure gas cylinder 220 on the hydrogen refueling vehicle 200. The user's facial image is then captured by the facial acquisition module 130 (which includes at least one camera) on the hydrogen refueling machine 100. The cloud server 300 then recognizes the facial image and sends the vehicle information and account balance information corresponding to the facial image to the station control computer 400 and the hydrogen refueling machine 100. The user confirms the vehicle information on the hydrogen refueling machine 100 (which has a display). Once the confirmation is correct, the fingerprint acquisition module 120 (which can use a fingerprint collector) captures the user's fingerprint and sends it to the cloud server 300. The cloud server 300 analyzes whether the user's fingerprint matches the user's facial image. If so, the cloud server 300 sends a refueling start instruction to the hydrogen refueling machine 100 via the station control computer 400 to authorize hydrogen refueling. During the hydrogenation process, the temperature sensor 221 provided on the high-pressure gas cylinder 220 detects the temperature of the high-pressure gas cylinder 220 in real time and sends it to the on-board controller 210; the pressure sensor 222 provided on the high-pressure gas cylinder 220 detects the pressure of the high-pressure gas cylinder 220 in real time and sends it to the on-board controller 210; the on-board controller 210 transmits the temperature, pressure and other information of the high-pressure gas cylinder 220 to the first infrared communication module 140 through the second infrared communication module 230, and the controller 110 on the hydrogenation machine 100 (the controller 110 can use a Loongson series processor) adjusts the gas filling parameters according to the above information received. At the end of the gas filling, the user pulls out the gas filling gun head of the hydrogenation machine 100, places it on the gas filling gun head placement rack of the hydrogenation machine 100, and can drive away; at the end of the gas filling, the cloud server 300 will deduct the corresponding fee from the user's account according to the gas filling amount (pipeline flow) detected by the flow meter 170, realizing a truly senseless payment. After deducting the corresponding fees, the cloud server 300 will also send a notification message to the user to let the user know the operating status of the high-pressure gas cylinder and the amount of hydrogen consumption during this hydrogenation process.

[0046] The station control computer 400 can be connected to multiple hydrogen refueling machines 100 to record and back up the refueling process information of the hydrogen refueling machines 100, and upload it to the cloud server 300. This refueling information includes account information, refueling time, refueling volume, refueling fee, and the temperature and pressure of the high-pressure gas cylinder during refueling. The monitoring camera 410 used for monitoring the hydrogen refueling station can also be connected to the station control computer 400 to monitor the operating status of the gas station and store the monitoring data.

[0047] Because rapid filling will cause the temperature of the gas cylinder to rise rapidly, long-term and repeated filling will cause thermal fatigue of the metal material, which is prone to dangers such as gun detachment. In the embodiment provided by this application, a gun detachment detection module 150 is also provided. The gun detachment detection module 150 is provided and includes a detection body, a detection hole is provided on the detection body, and an excitation ring and a detection ring are provided at the detection hole, wherein the excitation ring and the detection ring are respectively connected to the control circuit. A cable is provided on the hose of the filling gun. When filling, the cable, the filling gun and the device being filled (such as a car) can be well connected and conductive. The filling gun passes through the detection hole of the detection device without affecting the mechanical properties of the filling gun. Using the principle of electromagnetic induction, the control circuit controls the excitation ring to send a pulse magnetic field to the filling gun. If the filling gun is well connected to the device being filled (such as a car), a pulse current can be generated on the cable and the filling gun. Otherwise, no pulse current can be generated. The detection ring detects whether there is a pulse current and feeds back to the control circuit to output a corresponding detection signal, thereby realizing gun detachment detection.

[0048] An alarm device 160 may also be provided on the hydrogenator 100. The alarm device 160 is connected to the controller 110. The controller 110 may activate the alarm device 160 to issue an alarm prompt when the temperature, pressure, etc. of the high-pressure gas cylinder 220 are abnormal. The alarm device 160 may be an audible and visual alarm device, which may issue an audible and visual alarm prompt when the temperature, pressure, etc. of the high-pressure gas cylinder 220 are abnormal. In one embodiment, corresponding thresholds may be set based on the upper pressure limit and the upper temperature increase rate limit of the high-pressure gas cylinder 220. When the pressure or temperature increase rate of the high-pressure gas cylinder 220 exceeds the set threshold, the controller 110 activates the audible and visual alarm device 160 to issue a voice prompt and flash an alarm light.

[0049] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
