[0031] It should be noted that, in the above-mentioned embodiments of the present application, the above-mentioned fluid may further include gas and liquid.

Optionally, the volume in the storage unit 3 may be the total volume of the storage unit 3, to indicate the deformation of the storage unit 3 when storing the liquid; in another optional manner, the volume may be used to indicate the remaining volume in the storage unit 3, to indicate the volume of the liquid that can be further stored in the storage unit; the liquid pressure may specifically be the liquid pressure at the bottom of the storage unit 3, because corresponding to the same liquid, liquids at different heights may generate corresponding hydraulic pressures of different magnitudes at the bottom of the container, and thus the volume of the liquid stored in the storage unit 3 may be accurately indicated by the liquid pressure.

[0040] Alternatively, if Figure 2As shown, the transmission unit 2 includes: a fluid valve 7, which is connected to the storage unit 3; a one-way valve 8, the inlet end of the one-way valve 8 is connected to the switch 5, and the outlet end of the one-way valve 8 is connected to the fluid valve 7. It can be understood that the one-way valve 8 can control the fluid to be transmitted in the transmission unit 2 in the direction from the fluid inlet 5 to the storage unit 3. The one-way valve 8 can control the fluid to be transmitted in a predetermined direction, thereby avoiding the reverse transmission of the fluid during the transmission process, thereby ensuring the safety of the fluid transmission process. In addition, when the transmission state of the fluid transmission path is switched by using the switch 5, the one-way valve 8 can avoid the reverse transmission of the fluid caused by the change of the fluid transmission state, thereby improving the safety of the fluid transmission process.

[0041] In an optional embodiment, the one-way valve 8 can also be used to control the on-off of the fluid transmission channel according to the connection status of the electrical connection. In the above case, the fluid storage controller 6 can control the connectivity of the switch 5 according to the storage status indicated by the detected status parameters, and the fluid storage controller 6 can also control the connectivity of the one-way valve 8 according to the connection status of the electrical connection; in another optional embodiment, the fluid storage controller 6 can control the connectivity of the one-way valve 8 according to the storage status indicated by the detected status parameters, and the fluid storage controller 6 can also control the connectivity of the switch 5 according to the connection status of the electrical connection; in the above two embodiments, through the combined action of the one-way valve 8 and the switch 5, on the one hand, it can ensure that the transmission of the fluid is interrupted when the storage status is abnormal; on the other hand, when the electrical connection fails and the accurate storage status or control status cannot be obtained in time, the transmission of the fluid can be interrupted, thereby ensuring the safety of the fluid transmission process.

[0042] Alternatively, if Figure 3 As shown, the above fluid storage system further includes: a communication unit 9, electrically connected to the condition monitor 4, for sending the storage condition indicated by the condition parameter monitored by the condition monitor 4 to the fluid source.

[0043] It can be understood that, in this embodiment, the communication unit 9 included in the above-mentioned fluid storage system can send the storage status indicated by the status parameters monitored by the status monitor 4 to the fluid source, so that in the process of transporting the fluid to the above-mentioned fluid storage system through the fluid source, the storage status indicated by the relevant status parameters in the storage unit 3 can be fed back to the fluid source, thereby providing an accurate basis for the transmission control operation of the fluid source during the fluid transmission process, thereby improving the safety of the fluid transmission process.

[0044] In an optional embodiment, in an optional embodiment, the fluid storage controller 6 can control the connectivity state of the one-way valve 8 according to the storage state indicated by the detected status parameter, and the fluid storage controller 6 can also control the connectivity state of the switch 5 according to the connection state of the electrical connection of the above-mentioned communication unit 9; in the above two embodiments, through the combined action of the one-way valve 8 and the switch 5, on the one hand, it can be ensured that when the storage state is abnormal, the transmission of the fluid is interrupted by the one-way valve 8; on the other hand, when the electrical connection of the communication unit 9 fails and the fluid source cannot obtain the accurate storage state or control state through the electrical connection channel established by the above-mentioned communication unit 9, the transmission of the fluid can be interrupted by the above-mentioned switch 5, thereby ensuring the safety of the process of fluid filling through the fluid filling system and the above-mentioned fluid storage system.

[0045] The communication unit 9 may include, but is not limited to, a Bluetooth communication unit providing a Bluetooth communication connection, a wireless local area network communication unit providing a WIFI connection, or a short field communication unit providing a ZigBee connection. Preferably, the communication unit 9 includes an infrared transceiver to provide an infrared communication connection with the fluid source.

[0046] like Figure 4 As shown, the above-mentioned fluid storage system also includes: an alarm unit 10, which is electrically connected to the condition monitor 4, and is used to send alarm information representing the storage condition of the storage unit 3 according to the condition parameters monitored by the condition monitor 4, and the alarm information includes at least one of an acoustic alarm and a light alarm.

[0047] It can be understood that in this embodiment, when the storage condition of the above-mentioned storage unit 3 is in an abnormal state, an alarm message can be sent through the alarm unit 10 in the above-mentioned fluid storage system, and the above-mentioned prompting method can include but is not limited to: sending an alarm message to a specific terminal; playing an alarm voice message; displaying an alarm message through a display device, etc., to prompt that the storage condition of the fluid in the process of storing the fluid in the above-mentioned fluid storage system is in an abnormal state, and at the same time, the above-mentioned transmission unit 2 can be turned off by adjusting the switch 5 to the disconnected state.

[0048] In the case where the above-mentioned fluid is gas, the embodiment of the present application further provides a fluid filling control system, such as Figure 5 As shown, it includes a fluid source and the above-mentioned fluid storage system. Optionally, the above-mentioned fluid storage system can be specifically a gas storage system. The above-mentioned fluid source includes a fluid storage module 11, a fluid filling module 12 connected to the fluid storage module 11, and a fluid filling controller 13 electrically connected to the fluid storage module 11 and the fluid filling module 12, wherein the fluid filling controller 13 is used to control the connection and disconnection between the fluid storage module 11 and the fluid filling module 12.

[0049] Optionally, the above-mentioned fluid source also includes a communication module 14, which is electrically connected to the fluid filling controller 13 and the communication unit 9 in the fluid storage system. The fluid filling controller 13 controls the connection and disconnection between the storage module 11 and the fluid filling module 12 according to the storage status indicated by the status parameters received by the communication module 14 from the communication unit 9.

[0050] It should be noted that the connection mode between the fluid filling controller 13 and the communication module 14 may be a first communication connection, and the connection mode between the communication module 14 and the communication unit 9 may be a second connection mode. The first communication connection and the second communication connection may be communication connection modes of the same type, or communication connection modes of different types. In a preferred embodiment, the first communication connection may be specifically an electrical connection to transmit a communication signal through a physical circuit; the second communication connection may be specifically a wireless connection mode, such as a Bluetooth connection, a WIFI connection, a ZigBee connection, etc. In this embodiment, the specific connection modes of the first communication connection and the second communication connection are not limited.

[0051] It is understandable that the connection state of the second communication connection may be determined according to the operating state of the electronic components related to the second communication connection, or may be determined according to the communication parameters of the second communication connection. For example, the connection state of the second communication connection may be determined according to the operating states of the plurality of electronic components used to implement the second communication connection, or may be determined according to parameters such as the communication rate, communication delay, and packet loss rate of the second communication connection.

[0052] In the above embodiment, the fluid source can obtain the fluid storage state in the above storage unit 3 through the above second communication connection, and control the fluid transmission process according to the fluid storage state through the fluid filling controller 13, thereby ensuring the safety in the process of transmitting the fluid to the fluid storage system;

[0053] In addition, in the above embodiment, when the first communication connection is established between the fluid storage controller 6 and the communication unit 9, the fluid storage controller 6 can obtain the connection state of the above second communication connection according to the communication unit 9 to determine whether to close the switch 5 to interrupt the fluid filling process. It can be understood that if the connection state of the above second communication connection is abnormal, the storage state in the storage unit 3 cannot be notified to the fluid filling controller 13 in the fluid source through the communication unit 9 in time, and then when the state is abnormal in the storage unit 3, the above fluid filling process cannot be interrupted in time. Furthermore, through the above embodiment, when the connection state of the above second communication connection is abnormal, the fluid storage controller 6 can notify the switch 5 to close the transmission unit 2, thereby ensuring the safety of the fluid filling process.

[0054] Optionally, the communication unit 9 may further include: an infrared signal sending module, wherein the infrared signal sending module is used to send infrared signals through the second communication connection; and an infrared signal generating module, wherein the infrared signal generating module is used to generate infrared signals according to status parameters.

[0055] The following Figure 5 The specific application scenario of the fluid filling control system shown is explained.

[0056] With the development of technology, hydrogen energy technology has become an important direction of technological development. It involves a wide range of fields, including automobiles, ships, bicycles, etc. When it comes to hydrogen energy, whether it is a hydrogen engine or a fuel cell engine, it is inseparable from the hydrogen storage system.

[0057] The existing operation of adding hydrogen to the hydrogen storage system is usually to add hydrogen through a pipeline in a hydrogen filling station. Figure 5 The fluid filling control system shown is applied to the hydrogen filling scenario at the above-mentioned transportation terminal.

[0058] Taking the hydrogen refueling scenario of vehicle terminals as an example, the above Figure 5The fluid source can be specifically a hydrogenation station, and the fluid storage system can be the above-mentioned hydrogen storage system in the vehicle terminal. In the above-mentioned embodiment of the present application, after the hydrogenation gun muzzle of the hydrogenation station and the hydrogenation port of the hydrogen storage system of the vehicle terminal are locked, the infrared device of the on-board hydrogen storage system is used to establish communication between the vehicle and the hydrogenation station, and transmit parameters, including tank volume, tank pressure, tank temperature, container type, etc. The hydrogenation station performs hydrogenation based on whether the status of the hydrogen storage system is normal or not. If it is normal, hydrogenation is started, and if it is abnormal, hydrogenation is not performed. In addition, if there is a situation in the above-mentioned vehicle system that the hydrogen storage system has no external infrared device (or the external infrared device is offline), the infrared device of the hydrogenation station is abnormal, and the infrared module at the vehicle end is abnormal, the above-mentioned fluid storage controller 6 can be used to control the switch 5 to close the transmission unit 2 (hydrogen storage pipeline), thereby ensuring safety during the hydrogenation process.

[0059] Alternatively, if Figure 5 In the fluid filling control system shown, the communication module 14 may include: an infrared signal receiving module, wherein the infrared signal receiving module is used to receive the infrared signal in the above-mentioned second communication connection.

[0060] In a specific embodiment, the infrared signal receiving module included in the above-mentioned communication module 14 can be specifically an infrared device of a hydrogen refueling station, the infrared signal sending module included in the above-mentioned communication unit 9 can be specifically an external infrared device of a vehicle terminal hydrogen storage system, and the above-mentioned infrared signal generating module can be specifically a vehicle-end infrared module.

[0061] Alternatively, if Figure 6 As shown, the above-mentioned condition monitor 3 may also include: a temperature sensor, a pressure sensor and a concentration sensor.

[0062] The temperature sensor is used to obtain the temperature state of the storage unit 3. Optionally, in the vehicle-mounted hydrogen storage system, the storage unit 3 may be a hydrogen storage bottle. Correspondingly, the temperature sensor is used to obtain the temperature state of the hydrogen storage bottle in the hydrogen storage device; the pressure sensor is used to obtain the pressure state; and the pressure sensor is used to obtain the hydrogen concentration state in the hydrogen storage bottle.

[0063] Optionally, the above-mentioned fluid storage system also includes: a high-pressure pipeline and a medium-pressure pipeline, wherein the high-pressure pipeline is sealed and connected to the medium-pressure pipeline through a pressure reducing valve, and the high-pressure pipeline is sealed and connected to the hydrogenation pipeline, and the pressure state includes a high-pressure pressure state in the high-pressure pipeline, and a medium-pressure pressure state in the medium-pressure pipeline.

[0064] Specifically, in this embodiment, if Figure 7As shown, the on-board hydrogen storage system may include a hydrogen storage bottle, a bottle valve, a high-pressure pipeline, a pressure reducing valve, a medium-pressure pipeline, a hydrogen storage controller HMS, an infrared controller, etc. Correspondingly, the temperature sensor may be used to obtain the gas temperature in the hydrogen storage bottle during the hydrogenation process; the pressure sensor may be used to obtain the pressure state in the hydrogen storage bottle, the medium-pressure pipeline, and the high-pressure pipeline during the hydrogenation process. The high-pressure pipeline is sealed with the medium-pressure pipeline through the pressure reducing valve, and the high-pressure pipeline is sealed with the hydrogenation pipeline; the concentration sensor may be used to obtain the gas concentration in the hydrogen storage bottle to determine the operation progress of the current hydrogenation operation.

[0065] It can be understood that the above temperature state, pressure state and hydrogen concentration state all correspond to normal state intervals. In an optional manner, when the above hydrogen storage device obtains the state parameters corresponding to the above states, it can determine whether the current hydrogenation state is normal according to the comparison result between the current state parameters and the normal state parameters, and send a signal to the above hydrogen storage controller (corresponding to Figure 5 The fluid storage controller 6 in the fluid storage controller sends the corresponding status information, and in the event of an abnormal hydrogenation state, the one-way valve (corresponding to Figure 2 The one-way valve 8) in the hydrogenation pipeline is cut off to interrupt the hydrogenation process and ensure the safety of the hydrogenation process.

[0066] Alternatively, if Figure 7 The hydrogenation control system shown may further include: an alarm module, which is used to send an alarm prompt message when the hydrogenation pipeline is closed by a safety lock, and the alarm prompt message is used to indicate that the infrared communication connection is in an abnormal state.

[0067] It can be understood that in this embodiment, when the above-mentioned infrared communication connection is in an abnormal state, the alarm information can be prompted through the alarm module in the above-mentioned hydrogenation control system, and the prompt method can include but is not limited to: sending alarm information to a specific terminal; playing alarm voice information; displaying alarm information through a display device, etc., to prompt that the above-mentioned second communication connection is in an abnormal state during the hydrogenation process, and at the same time closing the above-mentioned hydrogenation pipeline through a safety lock.

[0068] It should be noted that the first communication connection and the second communication connection involved in the hydrogenation control system disclosed in the utility model, and other communication-related methods are all existing communication methods, including but not limited to: wired communication and wireless communication, etc.; the control methods involved in the control instructions in the hydrogenation control system of the utility model are also existing control methods, including but not limited to: temperature control, pressure control, concentration control, etc.

[0069] The following combination Figure 7 A complete embodiment of the present application is described.

[0070] like Figure 7 As shown, in this embodiment, the hydrogen storage device includes a hydrogen bottle valve, a hydrogen storage controller, a sensor, an infrared controller and an infrared transmitter; the hydrogen filling gun includes a one-way valve, a safety lock and a hydrogen filling port. In this embodiment, the hydrogen storage controller establishes a communication connection with the above-mentioned safety lock, so that when the hydrogen storage controller obtains the communication status between the hydrogen storage device and the hydrogen filling controller in real time, the safety lock is controlled according to the communication status.

[0071] It can be understood that during the hydrogen refueling process, the working mode of hydrogen refueling of the hydrogen storage bottle is that after the hydrogen refueling gun muzzle of the hydrogen refueling station and the hydrogen refueling port of the hydrogen storage system are locked, the infrared model of the on-board hydrogen storage system establishes communication between the vehicle and the hydrogen refueling station and transmits parameters, including tank volume, tank pressure, tank temperature, container type, etc. The hydrogen refueling station refuels based on whether the status of the hydrogen storage system is normal or not. If it is normal, hydrogen refueling will start, and if it is abnormal, hydrogen refueling will not be carried out.

[0072] If one of the following three situations occurs: the hydrogen storage system has no external infrared device, or the infrared device at the hydrogen filling station is abnormal, or the infrared module on the vehicle is abnormal, there will be risks in continuing the hydrogenation operation. If a part of the hydrogen storage system is in an abnormal state at this time, but the abnormal state cannot be correctly fed back due to these three reasons, accidents are likely to occur during the hydrogenation process.

[0073] In a specific embodiment of the present application, a safety lock device is added between the hydrogenation port and the one-way valve of hydrogenation. The safety lock device can be, but is not limited to, a lock for starting the switch on the hydrogenation gun. A signal receiver (the signal receiver can be one or more) is installed in the safety lock device. The signal receiver can be, but is not limited to, receiving an electrical signal or an infrared signal, etc. Here, an electrical signal is taken as an example. The signal received by the signal receiver in the safety lock device is 0. It can be, but is not limited to, when the received electrical signal is low level, or the preset received low level signal ratio is greater than the preset value, the hydrogenation control system is used normally, and the safety lock device is in an open state (that is, the lock of the hydrogenation gun is open). When the hydrogenation operation is performed in this state, the pipeline from the hydrogenation port to the hydrogen bottle is in an unobstructed state, and the hydrogenation gun can perform normal hydrogenation operations through the hydrogenation pipeline.

[0074] When any one or more of the following three conditions occur: the hydrogen storage system has no external infrared device; the infrared device at the hydrogen filling station is abnormal; the infrared module on the vehicle side is abnormal, the hydrogen storage controller can control the switch of the safety lock according to the status of the hydrogen storage system to achieve the purpose of controlling whether to continue hydrogenation. If the hydrogen storage system is in an abnormal state at this time and cannot meet the hydrogenation demand, but the hydrogenation port has been connected to the hydrogenation gun and is preparing for hydrogenation or is in the process of hydrogenation, in order to avoid dangerous conditions, the controller can send a signal 1 to the safety lock, and the safety lock is closed to block the hydrogenation process.
