Description

Technical Field

[0001] This application relates to the field of control technology, and in particular to a control method and related apparatus. Background Technology

[0002] Air-powered systems that incorporate air springs, such as air suspension systems, are widely used in various fields, including rail transportation, due to their advantages such as good shock absorption, adjustable height, and strong load-bearing capacity. Taking vehicles as an example, the vehicle height and suspension system stiffness can be adjusted by changing the air pressure inside the air springs, allowing the vehicle to better adapt to road conditions and driving situations during operation, reducing vehicle vibration, and improving driving stability and comfort.

[0003] To prevent moisture in the gas from corroding hardware such as motors and affecting system reliability, the gas in the air passage of an air spring system must be dry. Therefore, air spring systems have high requirements for the dryness of the gas in the air passage.

[0004] Taking the maintenance of an air spring system as an example, when the air spring system needs to be replenished with dry air, it is difficult to obtain dry air. Summary of the Invention

[0005] This application provides a control method and related apparatus that can effectively reduce the gas supply system's need for dry gas replenishment while meeting the gas demand of the gas supply system.

[0006] In a first aspect, embodiments of this application provide a control method applied to a first control device, which can be used to control a gas source system. The first control device is, for example, a controller for the gas source system. Executing this control method can effectively reduce the gas supply requirement of the gas source system while meeting its gas consumption needs. The following description uses the first control device as an exemplary execution subject.

[0007] The control method includes: a first control device acquiring a first command, and then, in response to the first command, controlling the dry gas in a first gas storage device in the gas source system to be discharged to a second gas storage device in the gas source system. The second gas storage device is a device in the gas source system other than the first gas storage device capable of storing gas.

[0008] It is understood that gas source systems have high requirements for the dryness of the gas in the gas path. In some scenarios, the first gas storage device of the gas source system has a need for venting, but the total gas volume of the entire gas source system does not need to be reduced. For example, if the first gas storage device malfunctions and needs repair, or if the first gas storage device reaches the end of its service life and needs to be replaced, venting the dry gas in the first gas storage device outside the gas source system will result in a loss of the total dry gas volume in the entire gas source system, which may require replenishment of dry gas source to operate normally. However, it is difficult to obtain a dry gas source that meets the gas path requirements of the gas source system. Therefore, in the above scenarios, the method of this application embodiment controls the dry gas in the first gas storage device to be vented to other gas storage devices (second gas storage devices) in the gas source system for storage, avoiding the waste of dry gas in the gas source system, thereby improving the utilization rate of the existing dry gas in the gas source system, and thus effectively reducing the gas source system's need for replenishment of dry gas while meeting the needs of the gas source system. For example, the method of this application embodiment can realize the disassembly, repair, or replacement of the first gas storage device without an external dry gas source.

[0009] In one possible implementation of the first aspect, the aforementioned gas source system is a first terminal. The action of controlling the discharge of dry gas from the first gas storage device in the gas source system to the second gas storage device in response to a first instruction specifically includes: acquiring first information, which indicates the state of the first terminal. If the first information satisfies a first preset condition, the action of controlling the discharge of dry gas from the first gas storage device in the gas source system to the second gas storage device in response to the first instruction is then taken. The first preset condition indicates support for the discharge of dry gas from the first gas storage device to the second gas storage device.

[0010] In this embodiment, before responding to the first command, the first control device performs a conditional judgment. Only when a first preset condition is met does it control the dry gas in the first gas storage device to be discharged into the second gas storage device. By adding a conditional judgment, potential safety risks are avoided, misoperation is prevented, and the safety and reliability of the control operation are improved.

[0011] In one possible implementation of the first aspect, the first preset condition includes one or more of the following: the first terminal is in maintenance mode and / or lifting mode, and the first terminal is in low-voltage power-on state.

[0012] In this embodiment, the first preset condition is further elaborated with examples, which improves the executableness of the first control device in making condition judgments, makes the control logic clearer, and facilitates subsequent iteration and maintenance of the first preset condition.

[0013] In one possible implementation of the first aspect, the control method further includes: the first control device controlling the dry gas in the first gas storage device to be discharged outside the gas source system.

[0014] In this embodiment, in some scenarios, such as when the second gas storage device has limited gas storage capacity but the first gas storage device still has an exhaust demand, or when the second gas storage device malfunctions, the first control device can also control the dry gas in the first gas storage device to be discharged outside the gas source system, so as to flexibly meet the exhaust demand of the first gas storage device.

[0015] In one possible implementation of the first aspect, controlling the dry gas in the first gas storage device to be discharged outside the gas source system specifically includes: responding to a first command to control the dry gas in the first gas storage device to be discharged outside the gas source system.

[0016] For example, the first instruction can be used not only to instruct the dry gas in the first gas storage device to be discharged to the second gas storage device, but also to instruct the dry gas in the first gas storage device to be discharged outside the gas source system. For instance, in response to the first instruction, the first control device first controls the dry gas in the first gas storage device to be discharged to the second gas storage device, and then controls the dry gas in the first gas storage device to be discharged outside the gas source system.

[0017] In this embodiment, the first control device performs multiple operations in response to a single instruction, reducing the overhead and time required to acquire the instruction and improving execution efficiency.

[0018] In one possible implementation of the first aspect, controlling the dry gas in the first gas storage device to be discharged outside the gas source system specifically includes: the first control device acquiring a second instruction, and responding to the second instruction, controlling the dry gas in the first gas storage device to be discharged outside the gas source system.

[0019] In this embodiment, the first control device, under the instruction of the second command, controls the dry gas in the first gas storage device to be discharged outside the gas source system, decoupling different operations and enabling more flexible control over the discharge of the dry gas in the first gas storage device to be discharged outside the gas source system.

[0020] In one possible implementation of the first aspect, the control method further includes: controlling the dry gas in the first gas storage device to stop being discharged into the second gas storage device.

[0021] In this embodiment, the first control device can realize closed-loop management of the start-end of the control of the dry gas in the first gas storage device to the second gas storage device, so as to more flexibly control the process of the dry gas in the first gas storage device to the second gas storage device.

[0022] In one possible implementation of the first aspect, controlling the discharge of dry gas from the first gas storage device to the second gas storage device specifically includes: acquiring second information, the second information indicating the state of the first gas storage device discharging gas to the second gas storage device; and, if the second information satisfies a second preset condition, controlling the discharge of dry gas from the first gas storage device to the second gas storage device to stop. The second preset condition indicates that the discharge of dry gas from the first gas storage device to the second gas storage device is not supported.

[0023] In this embodiment, the first control device monitors the state of the dry gas in the first gas storage device being discharged to the second gas storage device through the second information, so as to control the dry gas in the first gas storage device to stop being discharged to the second gas storage device at the right time, thereby achieving more flexible exhaust management of the first gas storage device.

[0024] In one possible implementation of the first aspect, the second information includes one or more of the following: the duration of exhaust from the first gas storage device to the second gas storage device, the gas pressure in the first gas storage device, the gas pressure in the second gas storage device, and the status of the gas source system.

[0025] In this embodiment, by providing detailed examples of the second information, the process of the dry gas in the first gas storage device being discharged to the second gas storage device can be monitored more clearly, enabling the first control device to more accurately control the dry gas in the first gas storage device to stop being discharged to the second gas storage device.

[0026] In one possible implementation of the first aspect, the second preset condition includes one or more of the following sub-conditions: the gas pressure in the first gas storage device is less than or equal to the first threshold, the gas pressure in the second gas storage device is greater than or equal to the second threshold, the time for the first gas storage device to exhaust gas to the second gas storage device is greater than or equal to the first preset time, and the first gas storage device to exhaust gas to the second gas storage device fails.

[0027] For example, a failure in the first gas storage device to exhaust gas to the second gas storage device may include one or more of the following: a gas pump failure, a gas pipeline failure in the first gas storage device to exhaust gas to the second gas storage device, or a failure in the second gas storage device.

[0028] In this embodiment, the second preset condition is further elaborated with examples, which improves the executableness of the first control device in making condition judgments, makes the control logic clearer, and facilitates subsequent iteration and maintenance of the second preset condition.

[0029] In one possible implementation of the first aspect, the control method further includes: controlling the dry gas in the second gas storage device to fill the first gas storage device.

[0030] In this embodiment, when the first gas storage device needs to be replenished with dry gas, the first control device can control the dry gas in the second gas storage device to be replenished back into the first gas storage device. This allows the first gas storage device to be replenished without relying on external dry gas, thus realizing a closed-loop operation of dry gas recovery and reuse in the gas source system and improving the utilization rate of dry gas in the gas source system. In one possible implementation of the first aspect, the aforementioned control of the dry gas in the second gas storage device to fill the first gas storage device specifically includes: obtaining a third instruction, and responding to the third instruction, controlling the dry gas in the second gas storage device to fill the first gas storage device.

[0031] In this embodiment, the first control device executes the operation of filling the first gas storage device with dry gas from the second gas storage device only upon receiving a third instruction. This third instruction allows for more precise and flexible timing of the control. Furthermore, whether the third instruction is confirmed manually or by machine, the safety of filling the first gas storage device with dry gas from the second gas storage device can be ensured.

[0032] In one possible implementation of the first aspect, the above-mentioned control of the dry gas in the second gas storage device to fill the first gas storage device specifically includes: obtaining third information, the third information being used to indicate the installation status of the first gas storage device, and when the third information indicates that the first gas storage device is successfully installed, controlling the dry gas in the second gas storage device to fill the first gas storage device.

[0033] In this embodiment, the first control device uses third information to determine whether the conditions for controlling the dry gas in the second gas storage device to fill the first gas storage device are met, which improves the logic and safety of the control operation and effectively avoids safety risks caused by invalid operations and accidental touches. Furthermore, when the first control device can acquire the third information independently, it can continuously or periodically monitor the installation status of the first gas storage device. When the installation status of the first gas storage device meets certain conditions, it automatically controls the dry gas in the second gas storage device to fill the first gas storage device, improving the automation performance of the first control device.

[0034] In one possible implementation of the first aspect, the control method further includes: stopping the supply of dry gas from the second gas storage device to the first gas storage device.

[0035] In this embodiment, the first control device can realize closed-loop management of the start and end of the process of controlling the dry gas in the second gas storage device to fill the first gas storage device, so as to make more flexible use of the dry gas in the second gas storage device to replenish the first gas storage device.

[0036] In one possible implementation of the first aspect, stopping the supply of dry gas from the second gas storage device to the first gas storage device specifically includes: acquiring fourth information, which indicates the state of the dry gas from the second gas storage device supplying the first gas storage device; and stopping the supply of dry gas from the second gas storage device to the first gas storage device when the fourth information satisfies a third preset condition. The third preset condition indicates that it is difficult for the dry gas from the second gas storage device to supply the first gas storage device.

[0037] In this embodiment, the first control device monitors the state of the dry gas in the second gas storage device being supplied to the first gas storage device through the fourth information, so as to control the dry gas in the second gas storage device to stop supplying to the first gas storage device at an appropriate time, thereby achieving more flexible gas supply management of the first gas storage device.

[0038] In one possible implementation of the first aspect, the aforementioned fourth information includes one or more of the following: the duration for which the dry gas from the second gas storage device is supplied to the first gas storage device, the gas pressure in the first gas storage device, the gas pressure in the second gas storage device, and the status of the gas source system.

[0039] In this embodiment, by providing detailed examples of the fourth information, the process of the dry gas in the second gas storage device being filled into the first gas storage device can be monitored more clearly, enabling the first control device to more accurately control the filling of the first gas storage device.

[0040] In one possible implementation of the first aspect, the aforementioned third preset condition includes one or more of the following sub-conditions: the gas pressure in the first gas storage device is greater than or equal to the third threshold, the gas pressure in the second gas storage device is less than or equal to the fourth threshold, the inflation time of the first gas storage device is greater than or equal to the second preset time, and the first gas storage device malfunctions during inflation.

[0041] In this embodiment, the third preset condition is further illustrated with examples, which improves the executableness of the first control device in making condition judgments, makes the control logic clearer, and facilitates subsequent iteration and maintenance of the third preset condition.

[0042] In one possible implementation of the first aspect, the control method further includes: controlling the gas source system to replenish the drying gas.

[0043] In this embodiment, the first control device can also control the gas source system to replenish drying gas to maintain the total amount of drying gas in the gas source system within the required range. For example, the gas source system is equipped with an air pump and a desiccant in its gas path, and the first control device can control the air pump to start drawing gas from the atmosphere and using the desiccant to dry the gas.

[0044] In one possible implementation of the first aspect, the aforementioned control of the gas source system to replenish dry gas specifically includes: acquiring a fourth instruction, and responding to the fourth instruction to control the gas source system to replenish dry gas.

[0045] In this embodiment, the first control device controls the gas source system to replenish dry gas under the instruction of the fourth command, so as to flexibly respond to the gas replenishment operation of the gas source system.

[0046] In one possible implementation of the first aspect, the above-mentioned control of the gas source system to replenish dry gas specifically includes: obtaining a fifth instruction, the fifth instruction being used to indicate the total gas volume of the gas source system, and controlling the gas source system to replenish dry gas when the total gas volume is less than or equal to a fifth threshold.

[0047] In this embodiment, the first control device does not need to continuously acquire the total gas volume of the gas source system. It can acquire the total gas volume of the gas source system only when it receives the fifth instruction, which saves monitoring costs. Furthermore, it controls the gas source system to replenish dry gas only when the total gas volume is less than or equal to the fifth threshold, thus avoiding ineffective gas replenishment.

[0048] In one possible implementation of the first aspect, the control method further includes: a first control device sending fifth information, the fifth information being used to indicate the status information of the first gas storage device and / or the operation information of the first gas storage device.

[0049] For example, the fifth information includes the status information of the first gas storage device. For instance, the status information of the first gas storage device may include one or more of the following: the exhaust status of the first gas storage device, the charging status of the first gas storage device, and the gas pressure in the first gas storage device.

[0050] For example, the fifth information includes operational information about the first gas storage device. This operational information may include one or more of the following: operations being performed or determined to be performed by the first control device on the first gas storage device; suggested operations to be performed on the first gas storage device (or suggestions for the next operation on the first gas storage device, such as inflating the first gas storage device).

[0051] For example, the fifth information includes the status information of the first gas storage device and the operation information of the first gas storage device.

[0052] In this embodiment, the first control device can feed back the status information and / or operation information of the first gas storage device to other devices to achieve information synchronization, avoid information gaps, and improve control efficiency.

[0053] In one possible implementation of the first aspect, the aforementioned gas source system includes an air spring device and an air storage tank. If the first air storage device is an air spring device, the second air storage device can be an air storage tank. If the first air storage device is an air storage tank, the first air storage device can be an air spring device.

[0054] For example, the air spring device can be an air spring (abbreviated as air spring), or the air spring device can also be an air spring support.

[0055] For example, the above-mentioned gas storage tank is a high-pressure gas storage tank.

[0056] In this embodiment, when the air spring device requires maintenance, the first control device can control the dry air source in the air spring device to be discharged into the air storage tank for storage. After the air spring device is repaired, the dry gas stored in the air storage tank can be used to replenish the air spring device, thus enabling maintenance of the air spring device in scenarios where there is no external dry air source. Alternatively, when the air storage tank requires maintenance, the first control device can control the dry air source in the air storage tank to be discharged into the air spring device for storage. After the air storage tank is repaired, the dry gas stored in the air spring device can be used to replenish the air storage tank, thus enabling maintenance of the air storage tank in scenarios where there is no external dry air source.

[0057] Secondly, embodiments of this application provide a control method applied to a second control device. This second control device can send instructions to the controller of a gas source system to indirectly control the gas source system, thereby effectively reducing the gas supply requirement of the gas source system while meeting its gas consumption needs. Exemplarily, the second control device is a vehicle diagnostic device, a computing device other than a vehicle, such as a diagnostic instrument or computer, or a component within a diagnostic instrument, such as a chip. Alternatively, the second control device can be a software tool and / or hardware module within a computing device; no specific limitations are made here. The following description uses the second control device as an exemplary execution subject.

[0058] The control method includes: a second control device acquiring first demand information, the first demand information being used to instruct the controller of the gas source system to send a first instruction, and in response to the first demand information, sending the first instruction, the first instruction being used to instruct the dry gas in the first gas storage device in the gas source system to be discharged to the second gas storage device in the gas source system, the second gas storage device being a gas storage device other than the first gas storage device in the gas source system.

[0059] For example, the first demand information is the user's demand information. For instance, the second control device can obtain the user's demand information through the human-machine interaction unit of the second control device.

[0060] For example, the controller of the gas source system is the first control device in the first aspect described above.

[0061] In this embodiment, the second control device, responding to the first demand information, instructs the controller of the gas source system via a first command to control the drying gas in the first gas storage device to be discharged into another gas storage device (the second gas storage device) in the gas source system for storage. This avoids wasting the drying gas in the gas source system and improves the utilization rate of the existing drying gas in the gas source system. Thus, while meeting the needs of the gas source system, the replenishment demand for drying gas in the gas source system is effectively reduced. For example, the method in this embodiment can enable the disassembly and maintenance of the first gas storage device without an external drying gas source.

[0062] In one possible implementation of the second aspect, the first instruction is also used to instruct the dry gas in the first gas storage device to be discharged outside the gas source system.

[0063] In this embodiment, the above operation can be used as a fallback when the capacity of the second gas storage device to store dry gas reaches its limit or when it is difficult to store the dry gas in the first gas storage device. In addition, by indicating various information through the first command, instruction overhead is saved.

[0064] In one possible implementation of the second aspect, the control method further includes: a second control device sending a second instruction, the second instruction being used to instruct the dry gas in the first gas storage device to be discharged outside the gas source system.

[0065] In this embodiment, the second control device can send various commands to flexibly control the discharge of dry gas from the first gas storage device.

[0066] In one possible implementation of the second aspect, sending the second instruction specifically includes: acquiring the status information of the first gas storage device, and sending the second instruction when the status information of the first gas storage device meets a fourth preset condition. The fourth preset condition is used to indicate that the discharge of dry gas from the first gas storage device to the second gas storage device is not supported.

[0067] In this embodiment, the second control device can send a second command based on the status information of the first gas storage device, so that the timing of sending the second command is more appropriate and precise, so as to achieve precise control of the discharge of dry gas in the first gas storage device.

[0068] In one possible implementation of the second aspect, the control method further includes: a second control device acquiring second demand information, the second demand information being used to instruct the controller to send a second instruction.

[0069] For example, the second requirement information comes from the user.

[0070] In this embodiment, the second control device sends a second instruction under the instruction of the second demand information, realizing on-demand sending, avoiding the second control device from sending the second instruction incorrectly or at the wrong time, and improving the accuracy of sending the second instruction.

[0071] In one possible implementation of the second aspect, the control method further includes: the second control device sending a third instruction, the third instruction being used to instruct the control of the dry gas in the second gas storage device to be supplied to the first gas storage device.

[0072] In this embodiment, the second control device can use other gas storage devices (second gas storage devices) in the gas source system to fill the first gas storage device, thereby realizing the recycling of dry gas in the gas source system and improving the utilization rate of dry gas in the gas source system.

[0073] In one possible implementation of the second aspect, the control method further includes: a second control device acquiring third demand information, the third demand information being used to instruct the controller of the gas source system to send a third command.

[0074] In this embodiment, the second control device sends a third instruction under the instruction of the third demand information, realizing on-demand sending, avoiding the second control device from sending the third instruction incorrectly or at the wrong time, and improving the accuracy of sending the third instruction.

[0075] In one possible implementation of the second aspect, the control method further includes: a second control device acquiring fifth information, the fifth information being used to indicate the status information of the first gas storage device and / or the operation information of the first gas storage device.

[0076] For example, the fifth information includes the status information of the first gas storage device. For instance, the status information of the first gas storage device may include one or more of the following: the exhaust status of the first gas storage device, the charging status of the first gas storage device, and the gas pressure in the first gas storage device.

[0077] For example, the fifth information includes operational information about the first gas storage device. This operational information may include one or more of the following: operations being performed or determined to be performed by the first control device on the first gas storage device; suggested operations to be performed on the first gas storage device (or suggestions for the next operation on the first gas storage device, such as inflating the first gas storage device).

[0078] For example, the fifth information includes the status information of the first gas storage device and the operation information of the first gas storage device.

[0079] In this embodiment, the second control device can acquire the status information and / or operation information of the first gas storage device to achieve more precise control based on the status information and / or operation information of the first gas storage device.

[0080] In one possible implementation of the second aspect, the control method further includes: the second control device sending a fourth instruction, the fourth instruction being used to instruct the gas source system to replenish dry gas.

[0081] In this embodiment, the fourth instruction is used to instruct the gas source system to replenish dry gas, so as to avoid insufficient dry gas in the gas source system and affect the normal operation of the gas source system.

"Send information to A", where "to A" simply indicates the direction of information transmission, and A is the destination, does not limit "send information to A" to a direct transmission over the air interface. "Send information to A" includes sending information directly to A, as well as sending information indirectly to A through a transmitter. Therefore, "send information to A" can also be understood as "outputting information destined for A". Similarly, "receive information from A" indicates that the source of the information is A, including receiving information directly from A, as well as receiving information indirectly from A through a receiver. Therefore, "receive information from A" can also be understood as "inputting information from A".

[0102] This application provides a control method and related apparatus, relating to the field of control technology, such as the control of a gas source system. To more clearly describe the solution of this application, the relevant technical concepts involved in this application are introduced below.

[0103] Air spring system: The air spring system is a core component that uses the volume or pressure of air within an airbag to support the vehicle body. It can be used to achieve vehicle height adjustment and / or stiffness (softness) control. See also Figure 1 , Figure 1 This is a structural schematic diagram of an air spring device provided in an embodiment of this application. In a vehicle, the air spring and shock absorber are integrated together to form an assembly module, which is called an air spring strut. The air spring device in this embodiment can be... Figure 1 The air spring in the middle, or for Figure 1 The hollow spring support in the middle.

[0104] For example, in some maintenance scenarios, air spring device repair can refer to the repair of the air spring component, which may involve repairing or replacing only the air spring. In other scenarios, air spring device repair can refer to the repair of the air spring support component, which is performed by disassembling or replacing the entire air spring support, making it simpler and more convenient. In various air spring device repair procedures, it is necessary to release the gas in the air spring device to depressurize it before disassembling and repairing it.

[0105] Open air spring system: An open air spring system is an active suspension technology that is directly connected to the outside atmosphere. For example... Figure 2 As shown, Figure 2 A schematic diagram of an air spring system is provided. Figure 2 As shown, the air spring system includes an air pump, a high-pressure air tank, and an air spring assembly. The air pump generates high-pressure gas and stores it in the high-pressure air tank, which in turn stores the high-pressure gas. The working principle of the open air spring system is as follows: When the pressure or volume in the high-pressure air tank is sufficient, to raise the vehicle body, the valve between the high-pressure air tank and the air spring assembly is opened (e.g., the inflation solenoid valve is opened), allowing the high-pressure gas in the high-pressure air tank to enter the air spring assembly, achieving lifting. To lower the vehicle body, the exhaust solenoid valve of the air spring assembly is opened, allowing the gas in the air spring assembly to be directly discharged into the atmosphere. If the pressure or volume in the high-pressure air tank is insufficient, the air pump is controlled to draw air from the atmosphere, compress it, and store it in the high-pressure air tank. In the open air spring system, the air entering the system is filtered and dried to ensure that the gas entering the system is dry gas after impurities have been removed. However, for the open air spring system, if moisture or water enters the high-pressure air tank during replenishment, it can be discharged from the system through the exhaust process of the air spring assembly and will not remain in the system for an extended period.

[0106] Closed-loop air spring system: A closed-loop air spring system is an advanced suspension technology that utilizes internal air circulation. Its core lies in the essentially closed air passageway; the air circulates between the air spring unit, high-pressure air tank, and air pump, rather than being frequently exchanged with the external environment. See also Figure 3 , Figure 3This is a schematic diagram of another air spring system provided in this application embodiment. The working principle of the closed air spring system is as follows: When it is necessary to raise the vehicle body, air needs to be charged into the air spring device. The air inlet valve of the air spring device, such as solenoid valves 3 to 7, and the air outlet valve solenoid valve 2 of the high-pressure air tank are opened. The air pump is started to pump the high-pressure air pre-stored in the high-pressure air tank into the air spring device. When it is necessary to lower the vehicle body, the air outlet valve of the air spring device is opened, such as solenoid valves 4 to 8, and the air inlet valve solenoid valve 1 of the high-pressure air tank is opened. The air pump is started to draw the gas in the air spring into the high-pressure air tank for the next use. Since the gas in the closed air spring system circulates internally, if moisture enters, it is difficult to expel, posing a risk of corrosion to components such as the air pump, leading to system instability. Therefore, the closed air spring system has higher requirements for the dryness of the gas in the air circuit.

[0107] The above technical concepts may be applied to the following embodiments.

[0108] In the aforementioned air spring system, the air pressure in the air spring unit and the high-pressure air tank is relatively high, exceeding atmospheric pressure. For example, the air pressure in the air spring unit is typically between 0.5 MPa and 1.0 MPa (i.e., 5-10 atmospheres); the air pressure in the air tank is typically between 1.1 MPa and 1.8 MPa (i.e., 11-18 atmospheres). During the maintenance of existing air spring systems, before disassembling the air storage device in the system, such as the air spring unit or the high-pressure air tank, to avoid potential injury to engineers from high-pressure gas, the dry gas in the air spring unit or the high-pressure air tank must be released to the atmosphere for depressurization. After maintenance, the air storage device must be replenished with dry gas to ensure its normal operation.

[0109] Taking an air spring system as an example, if the total air volume in the system is insufficient, such as when the air pressure in the high-pressure air tank is lower than the pressure threshold, one approach is to supplement the drying gas by connecting an external drying gas source to the air tank. However, such an external drying gas source is not always readily available. Another approach involves starting an air pump to extract and compress air, then drying the compressed gas with a desiccant before storing it in the high-pressure air tank. Since the desiccant has limited water absorption capacity, after replenishing the high-pressure air tank with a certain amount of drying gas, a "backflushing" process is required. This involves heating the desiccant to precipitate the water, and then using some of the gas from the high-pressure air tank to blow back towards the desiccant, expelling the precipitated water through the desiccant exhaust port. The above drying gas replenishment process is complex, making it difficult to replenish the system with drying gas.

[0110] In view of the above problems, embodiments of this application provide a control method and related apparatus that effectively reduce the gas supply system's need for replenishing dry gas while meeting the gas demand of the gas supply system.

[0111] See Figure 4 , Figure 4 This is a schematic diagram of the system architecture of a control method provided in an embodiment of this application. For example... Figure 4 As shown, the first control device and the gas source system are deployed at the first terminal. The second control device can establish a communication connection with the first terminal (or the first control device) to transmit information and indirectly control the gas source system.

[0112] like Figure 4 The first terminal shown may include, but is not limited to, vehicles such as commercial vehicles, passenger cars, trains, airplanes, industrial vehicles (e.g., forklifts, trailers, tractors), engineering vehicles (e.g., excavators, bulldozers, cranes), etc. For example, the first terminal may also be a robot, industrial machine, etc., but this application embodiment does not specifically limit it in this way.

[0113] like Figure 4 The first control device shown is a controller for the gas supply system. When the first terminal is a vehicle, this first control device can be a computing device within the vehicle, such as an electronic control unit (ECU), vehicle integration unit (VIU), vehicle control unit (VCU), or domain controller (DC). The DC could be a vehicle domain controller (VDC), multi-domain controller (MDC), or a component within the controller, such as a chip. Alternatively, the first control device can be a software tool and / or hardware module within the aforementioned computing device; no specific limitations are imposed here.

[0114] like Figure 4 The illustrated gas supply system includes a first gas storage device, a second gas storage device, and a gas pump (or motor). Exemplarily, this gas supply system can be as described above. Figure 2 or Figure 3 In the air spring system shown, if the first air storage device is an air spring device, the second air storage device can be an air tank (such as a high-pressure air tank); if the first air storage device is an air tank (such as a high-pressure air tank), the second air storage device can be an air spring device.

[0115] Optionally, the gas source system may also include a greater number of gas storage devices. For example, the gas source system may also include a third gas storage device, which may be another gas storage tank. This application embodiment does not impose specific limitations on the number and type of gas storage devices in the gas source system.

[0116] Alternatively, the aforementioned gas supply system may further include one or more valve devices, such as... Figure 2 or Figure 3 The solenoid valve shown is an example. It is understood that the gas supply system may also include other components, but this application does not specifically limit this.

[0117] Figure 4 The second control device shown can instruct the first control device to control the gas source system to perform corresponding operations by sending instruction information, thereby indirectly controlling the gas source system in the first terminal. For example, the second gas storage device is used to perform one or more of the following: diagnosis, repair, and testing of components in the gas source system (such as the first gas storage device). For instance, the second control device can be a diagnostic instrument, a diagnostic tablet, a diagnostic computer, etc.

[0118] In one example, a "contact-type" connection is established between the second control device and the first terminal. For instance, a wired communication connection is established via a data cable. For example, if the first terminal is a vehicle, the second control device is connected to one end of the physical data cable, and the other end of the physical data cable is inserted into the on-board diagnostics (OBD) interface of the first terminal, establishing a communication connection with the first terminal. This enables functions such as monitoring the status of the first terminal, fault diagnosis, and control. Optionally, the second control device and the first terminal can also be connected via an expansion device, such as a docking station, current clamp, or multimeter.

[0119] In another example, a "contactless" connection is established between the second control device and the first terminal, such as through Bluetooth or a wireless protocol. For instance, a wireless vehicle communication interface box with Bluetooth or Wi-Fi capabilities is plugged into the OBD interface of the first terminal, and the maintenance personnel then pair the second control device with the box via Bluetooth or Wi-Fi, thereby establishing a communication connection between the second control device and the first terminal.

[0120] It is understood that the embodiments of this application are applicable to various connection methods between the second control device and the first terminal.

[0121] For example, the second control device can send a first instruction to the first control device, instructing the first control device to control the discharge of dry gas from the first gas storage device in the gas source system to the second gas storage device in the gas source system. In scenarios where the first gas storage device has a discharge requirement, the first control device is instructed to store the dry gas in the first gas storage device for later use.

[0122] As another example, the second control device can also receive demand information from a user and perform corresponding operations under the user's instructions. For instance, the second control device acquires first demand information, which instructs the controller of the gas source system ( Figure 4 The first control device (shown) sends a first command.

[0123] For example, the first control device can also provide feedback information to the second control device. For instance, in response to a first command, the second control device controls the discharge of dry gas from the first gas storage device into the second gas storage device. The second control device can then send fifth information to the first control device. This fifth information includes the status information of the first gas storage device and / or the operation information of the first gas storage device, thereby aligning the information between the first and second control devices and facilitating the user to obtain the status of the gas source system through the first control device.

[0124] It is understood that the first control device and the second control device can perform more operations, which will be described in detail below with reference to the accompanying drawings of the embodiments.

[0125] See Figure 5 , Figure 5 This is a flowchart illustrating a control method provided in an embodiment of this application. This control method is applied to a control device, such as... Figure 4 The first control device shown can control the gas supply system to effectively reduce the gas supply system's need for replenishing dry gas while meeting its gas consumption requirements. For example, this control method can be applied to maintenance or replacement of the first gas storage device in the gas supply system. Using the first control device as an example, the control method includes, but is not limited to, the following steps: Step S501: The first control device acquires the first instruction.

[0126] For example, the first control device can be used to control a gas source system, such as a controller for the gas source system, to effectively reduce the gas supply requirement of the gas source system while meeting its gas consumption needs. For example, the first control device and the gas source system are deployed at a first terminal, such as... Figure 4 The first terminal shown here, at this time the first control device is Figure 4 The first control device in the first terminal shown.

[0127] For example, the first instruction can be used to instruct the dry gas in the first gas storage device in the gas source system to be discharged to the second gas storage device in the gas source system. Under the first instruction, the dry gas in the first gas storage device is reduced, but the dry gas in the first gas storage device is still stored in the gas source system, avoiding the waste of dry gas source caused by discharging it outside the gas source system and the loss of the total dry gas source volume of the entire gas source system, thereby reducing the gas source system's need for replenishing dry gas.

[0128] Regarding the scenario where the first control device acquires the first instruction, for example, when the first gas storage device of the gas source system has an exhaust demand, but the total gas volume of the entire gas source system does not decrease, or the total gas volume of the gas source system does not exceed the maximum limit gas volume, for example, when the first gas storage device malfunctions and needs to be repaired, or when the first gas storage device reaches the end of its service life and needs to be replaced, in this case, the first control device can acquire the first instruction to achieve the goal of meeting the exhaust demand of the first gas storage device while avoiding the waste of dry gas source.

[0129] Regarding the method by which the first control device acquires the first instruction, at least the following possibilities exist: Scenario 1: The first control device directly acquires the first instruction. For example, the first instruction originates from a control device other than the first terminal, such as... Figure 4 The second control device shown allows the first control device to directly acquire the first instruction sent by the second control device. In another example, a device in the first terminal with communication capabilities, other than the first control device, acquires the instruction information sent by the second control device. This device parses the instruction information and then sends the first instruction to the first control device. In other words, the first control device acquires the first instruction sent by the device in the first terminal with communication capabilities, other than the first control device itself.

[0130] Scenario 2: The first control device indirectly obtains the first instruction through other devices. For example, the first instruction originates from a control device other than the first terminal, such as... Figure 4 The second control device is shown. The second control device sends a first instruction to the first terminal. After receiving the first instruction, the gateway of the first terminal forwards the first instruction directly or processes it before forwarding it to the first control device. For example, the first instruction can be sent to the first control device through various means such as the controller area network (CAN) bus of the first terminal or the vehicle Ethernet.

[0131] It is understood that the above description of the method by which the first control device obtains the first instruction is merely illustrative and does not constitute a limitation on the embodiments of this application. The embodiments of this application are applicable to various methods by which the first control device obtains the first instruction.

[0132] In step S502, the first control device responds to the first command and controls the dry gas in the first gas storage device in the gas source system to be discharged into the second gas storage device.

[0133] The gas source system includes a first gas storage device and a second gas storage device, where the second gas storage device is any other device in the gas source system capable of storing gas besides the first gas storage device. It can be understood that the gas source system is a "gas supply-gas consumption" system including at least two gas storage devices. For a single gas storage device, it may function as a "gas supply device" in some scenarios and as a "gas consumption device" in others. For example, in a scenario where dry gas in the first gas storage device is discharged into the second gas storage device, the first gas storage device functions as a "gas supply device." Exemplarily, this gas source system can be as described above. Figure 2 or Figure 3 The air spring system shown may also be a central air source system. The embodiments of this application do not specifically limit the structure of the air source system.

[0134] After receiving the first instruction, the first control device responds to the first instruction by executing the corresponding operation indicated by the first instruction: controlling the discharge of dry gas from the first gas storage device to the second gas storage device. It is understood that the normal operation of the gas source system requires the total volume of dry gas to be maintained within a normal range. If the total volume of dry gas in the gas source system is lower than the normal range, dry gas needs to be replenished. However, it is difficult to obtain dry gas that meets the gas path requirements of the gas source system, making replenishment difficult. Therefore, through the above operation, when there is a discharge demand in the first gas storage device, in order to avoid the waste of dry gas in the first gas storage device and the need to replenish dry gas in the gas source system, the first control device "transfers" the dry gas in the first gas storage device to the second gas storage device for storage, thus achieving the goal of satisfying the discharge demand of the first gas storage device while retaining the dry gas in the first gas storage device within the gas source system. During this process, the amount of dry gas in the first gas storage device decreases, and the gas pressure in the first gas storage device decreases. At the same time, the amount of dry gas in the second gas storage device increases, and the gas pressure in the second gas storage device increases. The total amount of dry gas in the gas source system is basically not lost or is lost very little, so that the total amount of dry gas in the gas source system is maintained within the normal range as much as possible, reducing the gas source system's need for replenishing dry gas.

[0135] For example, taking the air source system as an air spring system, when the first air storage device is an air spring device, the second air storage device can be an air tank, such as... Figure 3The high-pressure gas storage tank shown illustrates an operation where the first control device controls the discharge of dry gas from the first gas storage device to the second gas storage device. Specifically, the first control device controls the discharge of dry gas from the air spring device to the gas storage tank. For example, in an air spring device after-sales maintenance scenario, it is understood that the pressure of the dry gas in the air spring device is generally higher than atmospheric pressure. Before repairing or replacing the air spring device, to avoid potential safety risks due to high pressure, personnel need to first discharge the dry gas in the air spring device to depressurize it. In the method of this application embodiment, while depressurizing the air spring device, the dry gas in the air spring device is still stored in the gas source system for later use. Similarly, if the first gas storage device is a gas storage tank, the second gas storage device can be an air spring device. For example, in a scenario where the gas storage tank needs repair or replacement, the dry gas in the gas storage tank is stored in the air spring device as much as possible to avoid wasting the dry gas source. Refer to the relevant instructions for air spring device repair; these will not be elaborated here.

[0136] For example, with Figure 3 Taking the structure of the air spring system shown as an example, one possible implementation of the first control device controlling the discharge of dry gas from the first gas storage device to the second gas storage device is as follows: Figure 3As shown, taking a vehicle as an example, each of the four wheels of the vehicle has an air spring device on its inner side, namely the left front air spring device, the right front air spring device, the left rear air spring device, and the right rear air spring device. Solenoid valve 3 is the main air intake valve for the four air spring devices, and solenoid valve 8 is the main air outlet valve for the four air spring devices. Each air spring device corresponds to a separate solenoid valve switch, used to independently control the airflow of each air spring device. It can be understood that the inflation, deflation, disassembly, and maintenance of the four air spring devices are independent of each other. For example, if the left front air spring device malfunctions and needs repair or replacement, i.e., the first air storage device is the left front air spring device and the second air storage device can be a high-pressure air tank, then the first control device responds to the first command by controlling solenoid valves 7 and 8 to open, connecting the air path between the left front air spring device and the air pump, and then controls the air pump to start and solenoid valve 1 to open (i.e., open the air inlet of the high-pressure air tank). The air pump draws dry gas from the left front air spring device and compresses it, and then fills the high-pressure air tank with the compressed dry gas, thereby controlling the dry gas in the first air storage device to be discharged to the second air storage device. For example, in the case where the high-pressure gas tank needs maintenance or replacement, i.e., the first gas storage device is a high-pressure gas tank and the second gas storage device can be one or more air spring devices, such as four air spring devices, then the first control device responds to the first command, controls the solenoid valve 2 to open, and controls the air pump to start, open solenoid valves 3, 4, 5, 6 and 7, and uses the air pump to draw dry gas from the high-pressure gas tank, compress it and then fill it into the right rear air spring device, left rear air spring device, right front air spring device and left front air spring device through solenoid valves 4, 5, 6 and 7 respectively for storage.

[0137] Optionally, if the gas source system also includes a third gas storage device, the first control device can also discharge the dry gas in the first gas storage device to the third gas storage device. For example, while the first control device controls the discharge of the dry gas in the first gas storage device into the second gas storage device, the dry gas in the first gas storage device is also discharged into the third gas storage device. Alternatively, after the first control device controls the discharge of the dry gas in the first gas storage device into the second gas storage device, if the second gas storage device malfunctions or reaches its storage limit, and the dry gas in the first gas storage device is still not completely discharged, the first control device can then control the discharge of the dry gas in the first gas storage device to the third gas storage device for storage. That is, one or more gas storage devices other than the first gas storage device in the gas source system are used to store the dry gas in the first gas storage device, so as to reduce the waste of the dry gas in the first gas storage device.

[0138] Optionally, step S502, "The first control device responds to the first command and controls the discharge of dry gas from the first gas storage device in the gas source system to the second gas storage device in the gas source system," specifically includes: the first control device acquiring first information, and, if the first information satisfies a first preset condition, responding to the first command, controlling the discharge of dry gas from the first gas storage device in the gas source system to the second gas storage device in the gas source system. Wherein, the first information is used to indicate the status of the first terminal. The first preset condition is used to indicate support for the discharge of dry gas from the first gas storage device to the second gas storage device.

[0139] It is understandable that the first control device may not respond to the first instruction immediately after obtaining the first instruction. Instead, it may first determine whether the conditions for responding to the first instruction are met. For example, the first control device may detect the status of the first terminal by obtaining the first information in order to determine whether the first terminal supports the discharge of dry gas in the first gas storage device to the second gas storage device, or in other words, whether it supports responding to the first instruction when the first control device obtains the first instruction.

[0140] In one implementation, the action of the first control device acquiring the first information can occur before the first instruction. For example, the first control device can periodically acquire or continuously monitor and acquire the first information. After acquiring the first instruction, it then determines whether the first information meets the first preset condition, that is, whether it can respond to the first instruction and execute the corresponding operation. If the first preset condition is met, it controls the dry gas in the first gas storage device to be discharged to the second gas storage device.

[0141] In another implementation, the action of the first control device acquiring the first information can also occur after acquiring the first instruction. For example, after the first control device acquires the first instruction, in order to determine whether it can respond to the first instruction and execute the corresponding operation, it acquires the first information and determines whether the first preset condition is met. If the first preset condition is met, it controls the dry gas in the first gas storage device to be discharged to the second gas storage device.

[0142] For example, the state of the first terminal includes one or more of the following: the mode information of the first terminal, the power-on information of the first terminal, etc.

[0143] For example, the first preset condition includes one or more of the following: Item 1: The first terminal is in maintenance mode and / or lifting mode. It is understood that when the first air storage device needs maintenance or replacement, to ensure operational safety, the maintenance mode of the first terminal needs to be activated. For example, in maintenance mode, the automatic inflation / deflation function of the air spring system is suppressed, the vehicle height is fixed, and other functions of the first terminal are at least partially restricted or disabled to prevent accidental operation, thus facilitating user maintenance or replacement of the first air storage device. When the first air storage device is an air spring device, since the air spring device itself has the ability to adjust the vehicle height, when maintaining the air spring device, to prevent the air spring device from venting under vehicle pressure, the vehicle height can be fixed using a lift or similar means to facilitate maintenance. For example, the user can set the first terminal to be in maintenance mode and / or lifting mode via the central control screen, or the second control device can send a command to the first terminal instructing it to activate maintenance mode and / or lifting mode.

[0144] Item 2, the first terminal is in a low-voltage power-on state. It is understood that if the first gas storage device needs to be repaired or replaced, there may be safety risks if the first terminal is in a high-voltage power-on state during the manual repair of the first gas storage device. Therefore, in order to ensure the safety of operation, the high-voltage power of the first terminal can be reduced to maintain the basic functions of the first control device and other low-voltage electrical components in a low-voltage power-on state.

[0145] It is understood that the first preset condition may include more items, and the embodiments of this application do not specifically limit this.

[0146] In one implementation, if the first information satisfies multiple sub-conditions when the first preset condition includes multiple sub-conditions, then the first information is considered to satisfy the first preset condition.

[0147] Optionally, the control method further includes: step S503, whereby the first control device controls the dry gas in the first gas storage device to stop being discharged into the second gas storage device. It can be understood that the above steps S502 and S503 correspond to the start and end of the operation of the first control device controlling the discharge of dry gas from the first gas storage device into the second gas storage device, respectively, so as to realize the closed loop of controlling the discharge of dry gas from the first gas storage device into the second gas storage device, avoiding the gas source system from overloading and maintaining the stability of the gas source system.

[0148] In one implementation, step S503 specifically includes: a first control device acquiring second information, and, upon determining that the second information meets a second preset condition, controlling the drying gas in the first gas storage device to stop being discharged into the second gas storage device. The second information indicates the state of the first gas storage device discharging gas into the second gas storage device, and the second preset condition indicates that the discharge of drying gas from the first gas storage device into the second gas storage device is not supported.

[0149] It is understood that in the above implementation, during the process of controlling the dry gas in the first gas storage device to be discharged to the second gas storage device, the first control device can intermittently or continuously acquire second information to monitor the state of the exhaust gas from the first gas storage device to the second gas storage device, and determine the timing for stopping the discharge of dry gas from the first gas storage device to the second gas storage device based on the second information, thereby improving the exhaust efficiency of the first gas storage device. See also Figure 6 , Figure 6 This is a flowchart illustrating another control method provided in the embodiments of this application.

[0150] For example, the second information may include one or more of the following: the duration of exhaust from the first gas storage device to the second gas storage device, the gas pressure inside the first gas storage device, the gas pressure inside the second gas storage device, and the status of the gas source system. For instance, the first control device has a timing function or can call a timer on the first terminal to start timing from the beginning of controlling the exhaust of dry gas from the first gas storage device to the second gas storage device, thereby obtaining the duration of exhaust from the first gas storage device to the second gas storage device. As another example, one or more pressure sensors are installed in the gas pipeline of the gas source system. For instance, a first sensor is installed inside the first gas storage device or in the connecting pipeline to measure the gas pressure inside the first gas storage device; a second sensor is installed inside the second gas storage device or in the connecting pipeline to measure the gas pressure inside the second gas storage device. The first control device can acquire the pressure data measured by the first and second sensors to obtain the gas pressure inside the first and second gas storage devices. For example, the state of the gas source system may include the working state of the first gas storage device, the working state of the second gas storage device, the state of the gas pipeline of the gas source system, the state of one or more valves in the gas source system, etc. The state of the gas source system can reflect the state of the first gas storage device exhausting gas to the second gas storage device to a certain extent.

[0151] For example, the second preset condition may include one or more of the following sub-conditions: Sub-condition 1: The gas pressure in the first gas storage device is less than or equal to a first threshold. For example, the first threshold can be a preset threshold in the gas source system or a threshold set by the user. It can be understood that the gas pressure in the first gas storage device reflects the amount of dry gas in it. During the exhaust process of the first gas storage device, as more gas is discharged, the gas pressure in the first gas storage device gradually decreases. When the gas pressure in the first gas storage device is less than or equal to the first threshold, there is less dry gas in the first gas storage device. The first control device can then consider that the exhaust requirement of the first gas storage device has been met, and thus the first control device can control the dry gas in the first gas storage device to stop being discharged into the second gas storage device.

[0152] Sub-condition 2: The gas pressure in the second gas storage device is greater than or equal to the second threshold. For example, the second threshold can be a preset threshold in the gas source system or a threshold set by the user. It can be understood that as dry gas in the first gas storage device is discharged into the second gas storage device, the amount of dry gas in the second gas storage device gradually increases, and the gas pressure in the second gas storage device gradually increases. When the gas pressure in the second gas storage device is greater than or equal to the second threshold, the first control device can consider that the amount of gas in the second gas storage device is too large, possibly reaching the storage limit of the second gas storage device, making it difficult to continue storing dry gas. Therefore, the first control device can control the discharge of dry gas from the first gas storage device into the second gas storage device to stop.

[0153] Sub-condition 3: The time taken for the gas to be discharged from the first gas storage device to the second gas storage device is greater than or equal to a first preset time. For example, the first preset time can be a pre-set time, such as a safe discharge time preset in the gas source system, or a discharge time set by the user. It is understood that if the time taken for the gas to be discharged from the first gas storage device to the second gas storage device is greater than or equal to the first preset time, the user-set discharge time requirement may be met, and the first control device can control the dry gas in the first gas storage device to stop being discharged into the second gas storage device. Alternatively, if the user forgets to instruct the first control device to stop the first gas storage device from discharging, causing the first gas storage device to discharge beyond the system-set safe discharge time, the protection mechanism is automatically triggered, and the first control device controls the dry gas in the first gas storage device to stop being discharged into the second gas storage device.

[0154] Sub-condition 4: Failure in the discharge from the first gas storage device to the second gas storage device. For example, a failure in the discharge from the first gas storage device to the second gas storage device may include one or more of the following: a pump failure, a gas path failure in the discharge path from the first gas storage device to the second gas storage device, or a failure of the second gas storage device itself. It is understood that, in the event of a failure during the discharge process from the first gas storage device to the second gas storage device, to avoid potential safety risks, the first control device will control the drying gas in the first gas storage device to stop being discharged into the second gas storage device.

[0155] It is understood that the sub-conditions in the above-mentioned second preset condition are merely examples, and the second preset condition may include more sub-conditions. This application embodiment does not specifically limit this.

[0156] In one implementation, when the second preset condition includes multiple sub-conditions, if the second information satisfies at least one of the sub-conditions, then the second information is determined to satisfy the second preset condition.

[0157] Optionally, the control method further includes: step S504, whereby the first control device controls the dry gas in the first gas storage device to be discharged outside the gas source system.

[0158] In one implementation, step S504 specifically includes: a first control device responding to a first command to control the discharge of dry gas in the first gas storage device to the outside of the gas source system. Exemplarily, the first command is used not only to instruct the discharge of dry gas in the first gas storage device to the second gas storage device, but also to instruct the discharge of dry gas in the first gas storage device to the outside of the gas source system.

[0159] In another implementation, step S504 specifically includes: the first control device acquiring a second instruction, and in response to the second instruction, controlling the dry gas in the first gas storage device to be discharged outside the gas source system. For example, the second instruction is used to instruct the dry gas in the first gas storage device to be discharged to the gas source system.

[0160] In the two implementations of step S504 above, there are at least the following possible scenarios regarding the timing of step S504's execution: Exemplarily (implementation 1), step S504 occurs after step S502 or step S503. For example, the first instruction instructs that the dry gas in the first gas storage device be discharged into the second gas storage device first, and then the dry gas in the first gas storage device be discharged outside the gas source system. As another example, the first control device first obtains the first instruction, and in response to the first instruction, the first control device obtains the second instruction and responds to the second instruction. It is understandable that, when there is a need for exhaust in the first gas storage device, in order to avoid wasting the dry gas source, the first control device prioritizes controlling the dry gas in the first gas storage device to be discharged as much as possible into the second gas storage device in the gas source system for storage. If the storage capacity of the second gas storage device is insufficient, or if the gas storage device in the gas source system other than the first gas storage device cannot store or cannot fully store the dry gas in the first gas storage device, or if there is a malfunction in the process of the dry gas in the first gas storage device being discharged to the second gas storage device, such as a gas circuit malfunction or a malfunction of the second gas storage device, the first control device can also control the dry gas in the first gas storage device to be discharged outside the gas source system, such as being discharged into the air, so as to flexibly meet the exhaust needs of the first gas storage device in multiple ways.

[0161] Exemplarily (implementation method 2), step S504 can also occur simultaneously with step S502. For example, the first instruction instructs the first control device to discharge the dry gas in the first gas storage device to the second gas storage device and outside the gas source system. Another example is that the first control device simultaneously receives the first instruction and the second instruction, or simultaneously responds to the first instruction and the second instruction. It is understood that when rapid venting of the first gas storage device is required, or when the gas storage capacity of devices other than the first gas storage device in the gas source system is small and cannot fully meet the venting requirements of the first gas storage device, or when the total volume of dry gas in the gas source system exceeds the normal range and requires some dry gas to be discharged outside the gas source system, the first control device can also control the gas in the first gas storage device to be simultaneously discharged to the second gas storage device and outside the gas source system.

[0162] It is understood that through one or more of the operations in steps S502 to S504 described above, the exhaust requirements of the first gas storage device are basically met. For example, in this case, the user can perform maintenance, repair, or replacement of the first gas storage device.

[0163] Optionally, the control method further includes: step S505, whereby the first control device controls the dry gas in the second gas storage device to be supplied to the first gas storage device.

[0164] For example, after the user has repaired or replaced the first gas storage device, it is necessary to replenish the first gas storage device with dry gas in order to restore the gas source system to normal operation. Since at least part of the original dry gas in the first gas storage device is discharged to the second gas storage device for storage in step S502 above, and it is difficult to connect an external dry gas source or generate dry gas in the gas source system, the dry gas in the second gas storage device can be used to replenish the first gas storage device when the first gas storage device needs to be filled with gas.

[0165] Optionally, to ensure the safe charging of the first gas storage device, before the first control device controls the dry gas in the second gas storage device to charge the first gas storage device, the first control device needs to determine that the first gas storage device meets the charging conditions. For example, the first control device needs to determine that the first gas storage device has been successfully installed. In this implementation, step S505 has at least the following possible solutions: Option 1, step S505 specifically includes: the first control device acquiring a third instruction, and in response to the third instruction, controlling the dry gas in the second gas storage device to be filled into the first gas storage device.

[0166] In implementation method 1 of scheme 1, the third instruction is used to direct the dry gas in the second gas storage device to be supplied to the first gas storage device. The third instruction originates from a device other than the first terminal, for example, from... Figure 4The second control device is shown. For example, the second control device is a diagnostic instrument. After the user completes the installation of the first gas storage device, they send a third command to the first control device by operating the second gas storage device, instructing the first control device to control the dry gas in the second gas storage device to fill the first gas storage device. It can be understood that in this implementation, whether the first gas storage device meets the filling conditions is determined manually by the user, and the first control device is responsible for executing the corresponding operation indicated by the third command.

[0167] In implementation method 2 of scheme 1, the third instruction is used to indicate that the first gas storage device has been successfully installed. The third instruction originates from a device other than the first control device, for example... Figure 4 The second control device shown, or any device in the first terminal other than the first control device. After the operator or the device confirms that the first gas storage device has been successfully installed, it instructs the first control device to confirm the successful installation of the first gas storage device. After receiving the third instruction, the first control device automatically controls the dry gas in the second gas storage device to fill the first gas storage device.

[0168] In implementation method 3 of scheme 1, before step S505, the control method further includes: the first control device sending fifth information, which is used to indicate the status information of the first gas storage device.

[0169] For example, the first control device to Figure 4 The second control device shown sends a fifth message. After receiving the fifth message, the second control device determines whether the first gas storage device meets the filling conditions based on the fifth message. If the second control device determines that the filling conditions of the first gas storage device are met, the second control device automatically sends a third instruction to the first control device, instructing the first control device to control the dry gas in the second gas storage device to fill the first gas storage device.

[0170] For example, the first control device directs... Figure 4 The second control device shown sends a fifth message. The user obtains the status information of the first gas storage device through the display unit of the second control device. The user determines whether the filling conditions of the first gas storage device are met based on the status information of the first gas storage device. If the user determines that the filling conditions of the first gas storage device are met, the user sends a third command to the first control device by operating the second control device, instructing the first control device to control the dry gas in the second gas storage device to fill the first gas storage device.

[0171] For example, the first control device sends a fifth message to the human-machine interaction unit of the first terminal. The user can obtain the status information of the first gas storage device through the human-machine interaction unit of the first terminal. The user determines whether the gas filling conditions of the first gas storage device are met based on the status information of the first gas storage device. If the user determines that the gas filling conditions of the first gas storage device are met, the user sends a third instruction to the first control device through the human-machine interaction unit of the first terminal, instructing the first control device to control the dry gas in the second gas storage device to fill the first gas storage device.

[0172] In implementation method 4 of Scheme 1, before step S505, the control method further includes: the first control device sending fifth information, which is used to indicate operation information for the first gas storage device. For example, the operation information for the first gas storage device can be a suggestion for the next operation procedure of the first gas storage device.

[0173] For example, the first control device can generate operational suggestions for the next operation of the first gas storage device based on information such as the status information of the first gas storage device or the status of the gas source system. For instance, it could suggest refilling the first gas storage device or using a second gas storage device to refill the first gas storage device. The first control device can then send the operational information for the first gas storage device to, for example,... Figure 4 The second control device or the human-machine interface unit of the first terminal shown can display the operation information. After the user clicks the confirmation button, the human-machine interface unit of the second control device or the first terminal sends a third command to the first control device. The first control device responds to the third command and controls the dry gas in the second gas storage device to fill the first gas storage device.

[0174] It is worth noting that the timing of the first control device sending the fifth information is merely illustrative. The first control device may also send the fifth information at one or more other times, such as at one or more times between steps S501 and S505. It is understood that the content indicated in the fifth information may differ depending on the timing at which the first control device sends the fifth information. This application embodiment does not specifically limit the timing of the first control device sending the fifth information.

[0175] Option 2, step S505 specifically includes: the first control device acquiring third information, the third information being used to indicate the installation status of the first gas storage device, and when the third information indicates that the first gas storage device is successfully installed, the first control device controlling the dry gas in the second gas storage device to fill the first gas storage device.

[0176] In implementation method 1 of scheme 2, regardless of whether the first gas storage device is successfully installed, the first control device can obtain third information, which indicates whether the first gas storage device is successfully installed or not. If the third information indicates that the first gas storage device is not successfully installed, the first control device does not perform the inflation operation. Optionally, if the third information indicates that the first gas storage device is not successfully installed, the first control device can also send... Figure 4 The second control device sends a prompt message to remind the user to install or adjust the first gas storage device. If a third message indicates that the first gas storage device has been successfully installed, the control device then controls the dry gas in the second gas storage device to fill the first gas storage device.

[0177] In implementation method 2 of Scheme 2, the first control device acquires the third information only when the first gas storage device is successfully installed. This third information indicates successful installation of the first gas storage device. For example, the installation interface of the first gas storage device is an integrated electrical contact interface. When the first gas storage device is successfully installed, the contacts at both ends of the installation interface are in contact or aligned, generating an electrical signal indicating circuit connection. When the first control device detects this electrical signal, it indicates successful installation of the first gas storage device. This electrical signal is the third information. Upon acquiring the third information, the first control device controls the dry gas in the second gas storage device to fill the first gas storage device. If the first gas storage device is not successfully installed, the contacts at both ends of the installation interface are not aligned or in contact, and the installation interface will not generate an electrical signal. The first control device cannot acquire the third information and will not execute step S505.

[0178] It is understood that the various implementations of step S505 described above are merely illustrative, and step S505 may have many more possible implementations. This application embodiment does not specifically limit these implementations.

[0179] Optionally, after step S505, the control method further includes: step S506, whereby the first control device controls the drying gas in the second gas storage device to stop being supplied to the first gas storage device.

[0180] In one implementation, step S506 specifically includes: a first control device acquiring fourth information, the fourth information being used to indicate the state of the dry gas in the second gas storage device being supplied to the first gas storage device; and when the fourth information meets a third preset condition, controlling the dry gas in the second gas storage device to stop being supplied to the first gas storage device.

[0181] It is understood that in the above implementation, during the process of stopping the supply of dry gas from the second gas storage device to the first gas storage device, the first control device can intermittently or continuously acquire fourth information to monitor the state of the second gas storage device supplying gas to the first gas storage device. Based on the fourth information, it determines the timing for stopping the supply of dry gas from the second gas storage device to the first gas storage device to prevent overcharging. See also Figure 7 , Figure 7 This is a flowchart illustrating another control method provided in the embodiments of this application.

[0182] For example, the fourth information includes one or more of the following: the duration for the dry gas from the second gas storage device to fill the first gas storage device, the gas pressure in the first gas storage device, the gas pressure in the second gas storage device, and the status of the gas source system. For details on how to obtain each item in the fourth information, please refer to the relevant explanations of each item in the second information above; these will not be repeated here.

[0183] For example, the third preset condition may include one or more of the following sub-conditions: Sub-condition one: The gas pressure inside the first gas storage device is greater than or equal to a third threshold. For example, the third threshold can be a preset threshold or a threshold set by the user. It can be understood that during the inflation process of the first gas storage device, as more dry gas is added, the gas pressure inside the first gas storage device gradually increases. When the gas pressure inside the first gas storage device is greater than or equal to the third threshold, the first control device can consider that the inflation requirement of the first gas storage device has been met, and then the first control device can control the dry gas in the second gas storage device to stop being added to the first gas storage device.

[0184] Sub-condition two: The gas pressure in the second gas storage device is less than or equal to the fourth threshold. For example, the fourth threshold can be a preset threshold or a threshold set by the user. It can be understood that as dry gas from the second gas storage device is supplied to the first gas storage device, the amount of dry gas in the second gas storage device gradually decreases, and the gas pressure in the second gas storage device gradually drops. When the gas pressure in the second gas storage device is less than or equal to the fourth threshold, the first control device can consider that the amount of gas in the second gas storage device is insufficient to continue supplying gas to the first gas storage device. Therefore, the first control device can control the supply of dry gas from the second gas storage device to the first gas storage device to stop.

[0185] Sub-condition three: the inflation time of the first gas storage device is greater than or equal to the second preset time. For example, the second preset time can be a preset duration, such as a safe inflation time preset in the gas source system, or an inflation time set by the user. For further explanation of sub-condition three, please refer to the relevant description of sub-condition 3 in the second preset condition above; it will not be repeated here.

[0186] Sub-condition four: First gas storage device charging failure. For example, a charging failure of the first gas storage device may include one or more of the following: air pump failure, gas path failure of the second gas storage device supplying gas to the first gas storage device, or a failure of the second gas storage device itself. It is understood that, in the event of a charging failure of the first gas storage device, to avoid potential safety risks, the first control device will control the drying gas in the second gas storage device to stop charging the second gas storage device.

[0187] It is understood that the sub-conditions in the above-mentioned third preset condition are merely examples, and the third preset condition may include more sub-conditions. This application embodiment does not specifically limit this.

[0188] In one implementation, if the third preset condition includes multiple sub-conditions, and the fourth information satisfies at least one of the sub-conditions, then the fourth information is determined to satisfy the third preset condition.

[0189] Optionally, the control method further includes: step S507, whereby the first control device controls the gas source system to replenish the drying gas.

[0190] It is understandable that during the normal operation of the gas source system, or after the operation of step S504 above, the total amount of dry gas in the gas source system may be lost, resulting in the total amount of gas in the gas source system being lower than the normal range. In order to maintain the normal operation of the gas source system, the first control device can also control the gas source system to replenish dry gas.

[0191] For example, with Figure 3 Taking the air spring system structure shown as an example, one way in which the "first control device controls the air source system to replenish drying gas" is as follows: The first control device controls solenoid valves 9 and 1 to open, while other solenoid valves are closed, controlling the air pump to start and drawing air from the air. After the gas passes through a one-way valve and solenoid valve 9, it reaches the air pump for compression, is dried by the desiccant, absorbs water, and then passes through solenoid valve 1 to fill the high-pressure air storage tank. Since the drying capacity of the desiccant is limited and cannot continuously dry a large amount of humid air, in order to maintain the dryness of the gas in the air source system, after replenishing a certain amount of drying gas to the high-pressure air storage tank, the air pump is stopped, and then the desiccant regeneration operation is performed. That is, the desiccant is heated, causing the water in the desiccant to separate out. Solenoid valve 3 is kept open, and a portion of the high-pressure drying gas stored in the high-pressure air storage tank, for example, 5% to 15% of the high-pressure drying gas in the high-pressure air storage tank, flows out. After the high-pressure gas is depressurized and expanded, it is blown back towards the desiccant, blowing the water separated from the desiccant out of the air source system through the desiccant outlet, thereby realizing the regeneration of the desiccant and maintaining its drying capacity. Repeat the above steps until the total volume of dry gas in the gas source system is within the normal range.

[0192] In one possible implementation, step S507 specifically includes: the first control device acquiring a fourth instruction, and in response to the fourth instruction, controlling the gas source system to replenish drying gas.

[0193] For example, the fourth instruction originates from Figure 4 The second control device shown allows the user to send a fourth command to the first control device. This fourth command instructs the control gas supply system to replenish drying gas, for example, instructing the first control device to perform the aforementioned gas replenishment and desiccant regeneration operations. In this implementation, the user determines whether to replenish the gas supply system with drying gas. Optionally, the first control device can also send status information of the gas supply system, such as to the aforementioned... Figure 4 The second control device sends status information of the gas source system. In this case, the user determines that the gas source system needs to be replenished with drying gas based on the status information of the gas source system sent by the first control device, and then operates the second control device to send a fourth command to the first control device. In another case, the user does not need to determine whether the current gas source system needs to be replenished with drying gas. Step S507 is a routine operation. For example, before the first terminal exits the diagnostic mode, the user operates the second control device to send a fourth command to the first control device.

[0194] For example, the fourth instruction originates from Figure 4 The second control device shown can send the status information of the gas source system to the first control device. Based on the status information of the gas source system, the second control device determines that the total gas volume of the gas source system is less than the fifth threshold. Then, the second control device can automatically send a fourth command to the first control device to instruct the control gas source system to replenish the drying gas.

[0195] In another possible implementation, step S507 specifically includes: the first control device acquiring a fifth instruction, the fifth instruction indicating the acquisition of the total gas volume of the gas source system; and, if the total gas volume of the gas source system is less than or equal to a fifth threshold, controlling the gas source system to replenish drying gas. For example, the fifth threshold is a preset threshold, such as the minimum value within the normal range of the total gas volume of the gas source system. See also... Figure 8 , Figure 8 This is a schematic flowchart of a method for replenishing drying gas in a gas source system, provided in an embodiment of this application.

[0196] It is understandable that, under this implementation, the first control device detects the total gas volume of the gas source system upon receiving the fifth instruction, for example, by... Figure 3 The pressure sensor shown acquires the total gas volume of the gas source system. If the total gas volume of the gas source system is greater than the fifth threshold, there is no need to replenish the drying gas. If the total gas volume of the gas source system is less than or equal to the fifth threshold, the control system replenishes the drying gas.

[0197] For example, the source of the fifth instruction can be found in the relevant description of the fourth instruction mentioned above, and will not be repeated here.

[0198] The implementation of step S507 described above is merely illustrative. There are many other possible implementations of step S507. The comparison of the embodiments in this application does not limit the specific implementation.

[0199] Through the above-described embodiments, when there is a need for exhaust in the first gas storage device, the dry gas in the first gas storage device is controlled to be discharged to the second gas storage device in the gas source system for storage, so as to avoid the waste of dry gas source. In order to make it possible to use the dry gas stored in the second gas storage device to fill the first gas storage device when the first gas storage device needs to be replenished with dry gas, thereby improving the utilization rate of dry gas and effectively reducing the gas source system's need for dry gas replenishment.

[0200] See Figure 9 , Figure 9 This is a flowchart illustrating another control method provided in an embodiment of this application. This control method is applied to a control device, such as... Figure 4 The second control device shown can instruct the first control device to control the gas source system to perform corresponding operations, thereby effectively reducing the gas supply system's need for dry gas replenishment while meeting its gas consumption requirements. For example, this control method can be applied to the maintenance or replacement of the first gas storage device in the gas source system. Using the second control device as an example, the control method includes, but is not limited to, the following steps: Step S901: The second control device acquires the first demand information.

[0201] For example, the second control device can establish a communication connection with the first terminal to transmit information. For instance, the second control device is... Figure 4 The second control device shown, or the one described above Figure 5 The second control device in the method embodiment is capable of communicating with the first control device in the first terminal and sending instruction information to instruct the first control device to perform corresponding operations, thereby indirectly controlling the gas source system in the first terminal. For example, the second gas storage device is used to perform one or more of the following tasks on components in the gas source system (such as the first gas storage device): diagnosis, repair, and testing. For instance, the second control device can be a diagnostic instrument, a diagnostic tablet, a diagnostic computer, etc.

[0202] The first demand information is used to instruct the second control device to send a first command to the controller of the gas source system. Exemplarily, the gas source system and its controller are deployed at the first terminal; for example, the gas source system is as described above. Figure 4 The gas source system shown can have a controller that is, for example, [missing information]. Figure 4The first control device shown, or the above-mentioned Figure 5 The first control device in the method embodiment shown.

[0203] For example, the first demand information comes from the user, and the first demand information is the user's demand information. Regarding the method by which the second control device acquires the first demand information, for example, the second control device includes a human-machine interface unit, such as a display screen, buttons, knobs, hard switches, etc., through which it acquires the user's demand information, such as the operation the user expects to perform. Another example is that the second control device receives the first demand information sent from other devices, for example, the user sends the first demand information to the second control device via a communication device such as a mobile phone. This application does not specifically limit the method by which the second control device acquires the first demand information.

[0204] In step S902, the second control device responds to the first demand information and sends a first command.

[0205] The first instruction is used to instruct the dry gas in the first gas storage device in the gas source system to be discharged to the second gas storage device in the gas source system.

[0206] It can be understood that the second control device acts as a "bridge" for communication between the user or other devices and the controller of the gas source system. The second control device sends instruction information to the controller of the gas source system, controlling the controller to perform corresponding operations. For example, the user can use the second control device to control the gas source system remotely, outside of the first terminal.

[0207] For the scenario where the second control device sends the first instruction, or the scenario where the second control device obtains the first demand information, please refer to the relevant description of the scenario where the first control device obtains the first instruction in step S501 above, which will not be repeated here.

[0208] In one implementation, the first instruction includes specific operational information for discharging dry gas from the first gas storage device in the gas source system to the second gas storage device in the gas source system, such as valve control, pump start / stop, and exhaust time. After obtaining the first instruction, the controller of the gas source system executes the corresponding operation according to the specific operational information indicated in the first instruction.

[0209] In another implementation, the first instruction includes one or more code identifiers, such as A0001. The second control device must forward the first instruction to the controller of the gas source system through the gateway of the first terminal. For example, the first terminal stores the correspondence between multiple code identifiers and execution operations. The gateway of the first terminal obtains the first instruction, and based on the code identifier A0001 in the first instruction and the correspondence between multiple code identifiers and execution operations, obtains the first operation corresponding to the code identifier A0001. The gateway of the first terminal then sends the first operation to the controller of the gas source system, instructing the controller of the gas source system to execute the first operation.

[0210] In another implementation, the first instruction includes one or more code identifiers, such as B0001. The second control device can communicate directly with the controller of the gas source system. The controller of the gas source system stores the correspondence between multiple code identifiers and execution operations. The controller of the gas source system obtains the code identifier B0001 in the first instruction. Based on the code identifier B0001 and the correspondence between multiple code identifiers and execution operations, the controller of the gas source system obtains the second operation corresponding to the code identifier B0001. The controller of the gas source system executes the second operation.

[0211] The above description provides an exemplary method for sending the first instruction. In addition to the above implementation method, the second control device may also send the first instruction in other ways, and this application embodiment does not specifically limit this.

[0212] Through the above step S902, when there is a need for exhaust in the first gas storage device of the gas source system, the dry gas in the first gas storage device can be indirectly controlled by the second control device to be discharged to other gas storage devices in the gas source system for storage, so as to avoid the waste of dry gas.

[0213] Optionally (implementation method 1), the first instruction is also used to instruct the dry gas in the first gas storage device to be discharged outside the gas source system.

[0214] For example, the first instruction may first instruct the dry gas in the first gas storage device to be discharged to the second gas storage device, and then instruct the dry gas in the first gas storage device to be discharged outside the gas source system, so as to store as much dry gas source as possible while meeting the exhaust requirements of the first gas storage device. Other explanations can be found in the relevant description of implementation method 1 in step S504 above, and will not be repeated here.

[0215] In another example, the first instruction can direct the dry gas in the first gas storage device to be simultaneously discharged into the second gas storage device and outside the gas source system. This improves the discharge efficiency of the first gas storage device while reducing the waste of dry gas through multiple discharge methods. Further explanations can be found in the relevant description of implementation method 2 in step S504 above, and will not be repeated here.

[0216] Alternatively (implementation method 2), as a parallel scheme to the above implementation method 1, the control method further includes: step S903, the second control device sends a second instruction, the second instruction being used to instruct the dry gas in the first gas storage device to be discharged outside the gas source system.

[0217] Regarding the timing of the second control device sending the second command, at least the following possibilities exist: For example, the second control device first sends a first command, and after determining that the controller of the gas source system has responded to the first command, the second control device sends a second command. It can be understood that, when the first gas storage device has an exhaust demand, to avoid wasting dry gas, the second control device prioritizes instructing the first control device to exhaust as much dry gas as possible from the first gas storage device into the second gas storage device for storage. If the storage capacity of the second gas storage device is insufficient, or if any other gas storage device in the gas source system besides the first gas storage device cannot store or fully store the dry gas in the first gas storage device, or if a malfunction occurs in the process of exhausting the dry gas from the first gas storage device to the second gas storage device (e.g., a gas path malfunction or a malfunction of the second gas storage device), the second control device then instructs the first control device to exhaust the dry gas from the first gas storage device outside the gas source system, for example, into the air, to flexibly meet the exhaust demand of the first gas storage device while reducing the waste of dry gas.

[0218] For example, the second control device first sends a first command, and then sends a second command after a first time interval. For example, the first time interval can be determined by the user; for instance, after the first time interval, the user operates the second control device and deems the second gas storage device to have essentially reached its storage limit, thus operating the second control device to send the second command.

[0219] For example, the second control device simultaneously sends a first command and a second command to instruct the gas source system to simultaneously discharge the dry gas in the first gas storage device into both the second gas storage device and the gas source system. This achieves the goal of quickly meeting the exhaust demand of the first gas storage device while reducing the waste of dry gas. Alternatively, after the second control device sends the first command and the second command, the controller of the gas source system determines the manner and timing of responding to the first command and / or the second command based on the status of the gas source system.

[0220] In one implementation of implementation method 2, step S903 specifically includes: the second control device acquiring the status information of the first gas storage device, and sending a second command when the status information of the first gas storage device meets a fourth preset condition. The fourth preset condition indicates that the dry gas in the first gas storage device is difficult to discharge to the second gas storage device.

[0221] For example, in this implementation, the second control device sends a second instruction after sending the first instruction. After instructing the controller of the gas source system to discharge the dry gas in the first gas storage device to the second gas storage device, the second control device monitors the status of the first gas storage device by acquiring its status information, in order to determine when to send the second instruction. For example, if the second control device determines, based on the status information of the first gas storage device, that a fourth preset condition is met, the second control device may automatically send the second instruction.

[0222] Optionally, the second control device may acquire the status information of the first gas storage device before sending the first command. For example, the second control device may acquire the status information of the first gas storage device intermittently or continuously. Alternatively, the second control device may acquire the status information of the second gas storage device after sending the first command. For example, after the controller of the gas source system responds to the first command, it feeds back the status information of the first gas storage device to the second control device. The embodiments of this application do not specifically limit the timing of the second control device acquiring the status information of the first gas storage device.

[0223] In another implementation of implementation method 2, before step S903, the control method further includes: the second control device acquiring second demand information, and the second demand information instructing the controller of the gas source system to send a second command.

[0224] It is understood that in this implementation, the second control device, in response to the second demand information, sends a second command to the controller of the gas source system. For example, the second demand information originates from the user. For instance, the user manually determines whether a second command needs to be sent to the controller of the gas source system, and when to send the second command.

[0225] The method by which the second control device obtains the second demand information can refer to the relevant description of obtaining the first demand information in step S901 above, and will not be repeated here.

[0226] Optionally, the control method further includes: step S904, whereby the second control device sends a third instruction, the third instruction being used to instruct the control of the dry gas in the second gas storage device to be supplied to the first gas storage device.

[0227] It is understandable that, in scenarios where the first gas storage device has been repaired or replaced, it is necessary to replenish the first gas storage device with dry gas in order to restore the gas source system and the first gas storage device to normal operation. Since the second control device sent a first command in step S902 to discharge the dry gas in the first gas storage device to the second gas storage device, it can be assumed that the second gas storage device stores at least part of the gas discharged from the first gas storage device. Furthermore, it is difficult for the gas source system to connect an external dry gas source to replenish the first gas storage device and generate dry gas. Therefore, when the first gas storage device needs to be replenished with dry gas, the dry gas in the second gas storage device can be used to fill the first gas storage device.

[0228] In one implementation, prior to step S904, the control method further includes: a second control device acquiring third demand information, the third demand information being used to instruct the controller of the gas source system to send a third command. It can be understood that in this implementation, the second control device, in response to the third demand information, sends a third command to the controller of the gas source system.

[0229] For example, the third demand information originates from the user, who manually determines when a third command can be sent to the controller of the gas source system, and the timing of sending the third command. For instance, the user manually determines that the first gas storage device has been successfully installed, or that the conditions for filling the first gas storage device have been met, and then inputs the third demand information to the second control device. The method by which the second control device obtains the third demand information can refer to the relevant description of obtaining the first demand information in step S901 above, and will not be repeated here.

[0230] In another implementation, before step S904, the control method further includes: the second control device acquiring fifth information, which is used to indicate the status information of the first gas storage device.

[0231] For example, the second control device can determine whether the first gas storage device meets the charging conditions based on the status information of the first gas storage device. If the charging conditions of the first gas storage device are met, such as when the first gas storage device is successfully installed, the second control device sends a third command to instruct the dry gas in the second gas storage device to be charged into the first gas storage device. Optionally, in this implementation, the second control device does not need to obtain the third demand information; the second control device can automatically send the third command when it is determined that the charging conditions of the first gas storage device are met.

[0232] Optionally, the second control device can also acquire other status information of the gas source system, such as the status information of the second gas storage device. Based on the status information of the first gas storage device and the status information of the second gas storage device, the second control device determines that it is possible to fill the first gas storage device with the dry gas in the second gas storage device, and then sends a third command.

[0233] For example, after the second control device obtains the status information of the first gas storage device, it can display the status information of the first gas storage device through the human-machine interaction unit (such as a display screen) of the second gas storage device. The user can determine whether to send the third request information based on the information displayed by the human-machine interaction unit (such as a display screen) of the second gas storage device.

[0234] In another implementation, before step S904, the control method further includes: the second control device acquiring fifth information, which is used to indicate operation information for the first gas storage device. For example, the operation information for the first gas storage device may include operation suggestions for the first gas storage device, such as whether to inflate the first gas storage device. Optionally, in this implementation, the second control device can also display operation information for the first gas storage device to assist the user in determining the operation to be performed on the first gas storage device. The user can respond to the fifth information by operating the second control device, such as "confirm execution," "cancel execution," or "delay execution." It can be understood that the third requirement information is the user's feedback information on the fifth information. Through the above operations, the entire operation process is made more standardized, avoiding missing steps and errors in the operation of the first gas storage device.

[0235] In another implementation, before step S904, the control method further includes: the second control device acquiring fifth information, which is used to indicate the status information of the first gas storage device and the operation information of the first gas storage device. It can be understood that in this implementation, the second control device has richer functions, enabling it to improve the accuracy and security of sending third commands based on more comprehensive information. For example, the second control device can display more diverse information to better assist the user in operating the second control device.

[0236] It is worth noting that, in addition to the timing of the second control device acquiring the fifth information as illustrated in the above implementation, the second control device may also acquire the fifth information at one or more other times, such as at one or more times between steps S901 and S904. It is understood that the content indicated in the fifth information may differ depending on the timing of the acquisition, and the method by which the second control device utilizes the fifth information may also differ. This application embodiment does not specifically limit the timing of the second control device acquiring the fifth information or the method by which it utilizes the fifth information.

[0237] Optionally, the control method further includes: step S905, whereby the second control device sends a fourth instruction to instruct the gas source system to replenish dry gas.

[0238] It is understood that after one or more of the operations in steps S902 to S904 above, the total gas volume of the gas source system of the first terminal may be lost, resulting in the total gas volume of the dry gas in the gas source system being lower than the normal range. In order to enable the gas source system to operate normally, the second control device can also instruct the controller of the gas source system to control the gas source system to replenish the dry gas through the fourth instruction.

[0239] In one possible implementation, before step S905, the method further includes: the second control device acquiring fourth demand information, which is used to instruct the controller of the gas source system to send a fourth command. For example, in this implementation, the user can determine whether to replenish the gas source system with drying gas. For instance, if the user determines that the gas source system needs replenishment with drying gas based on the status information of the gas source system acquired by the second control device, then inputs the fourth demand information to the second control device. As another example, if the user has input the second demand information to the second control device, the user can also determine an appropriate time to input the fourth demand information to the second control device. Yet another example, the user does not need to determine whether the current gas source system needs replenishment with drying gas; step S905 is an operation included in a conventional process, such as in the maintenance process of the first gas storage device, where the user inputs the fourth demand information to the second control device before the maintenance of the first gas storage device is completed and the gas source system returns to normal operation.

[0240] In another possible implementation, the second control device can acquire the status information of the gas source system, such as the total amount of gas in the gas source system. Based on the status information of the gas source system, if the second control device determines that the total amount of gas in the gas source system is less than or equal to the fifth threshold, then the second control device can automatically send a fourth instruction to the first control device to instruct the control gas source system to replenish the drying gas.

[0241] Optionally, the control method further includes: step S906, whereby the second control device sends a fifth instruction, the fifth instruction being used to instruct the acquisition of the total gas volume of the gas source system. It can be understood that in this implementation, the second control device can also instruct the controller of the gas source system to detect the total gas volume of the gas source system. For example, in some scenarios, such as gas source system maintenance scenarios, the automation function of the gas source system controller is limited, and it cannot spontaneously monitor the total gas volume of the gas source system, which may lead to the failure to detect insufficient total gas volume in the gas source system in a timely manner, and failure to replenish the dry gas source in a timely manner. In this embodiment, the second control device instructs the controller of the gas source system to detect the total gas volume of the gas source system through the fifth instruction, so that when the total gas volume of the gas source system is insufficient, for example, when the total gas volume of the gas source system is less than or equal to a fifth threshold, it can promptly detect and take corresponding measures. Optionally, step S906 specifically includes: the second control device can acquire fifth demand information, the fifth demand information being used to instruct the sending of a fifth instruction to the controller of the gas source system, and the second control device responding to the fifth demand information by sending the fifth instruction.

[0242] In one implementation, steps S905 and S906 are parallel schemes, and the second control device selects one to execute.

[0243] In another implementation, when both steps S905 and S906 are executed, step S906 can occur after step S905. For example, after the second control device instructs to replenish the gas supply system with dry gas, it then instructs to detect the total gas volume of the gas supply system to determine whether the dry gas replenished to the gas supply system is sufficient or whether the total gas volume of the gas supply system is within the normal range.

[0244] In one implementation, when both steps S905 and S906 are executed, step S905 can occur after step S906. For example, after the second control device sends the fifth instruction, it obtains the total gas volume of the gas source system from the controller of the gas source system. If the second control device determines that the total gas volume of the gas source system is lower than the normal range, it sends the fourth instruction.

[0245] Using the method described in the above embodiments, when there is a need for exhaust in the first gas storage device, the second control device can instruct the controller of the gas source system to discharge the dry gas in the first gas storage device to other gas storage devices (second gas storage devices) in the gas source system for storage, so as to reduce the waste of dry gas. In order to facilitate the use of the dry gas stored in the second gas storage device to replenish the first gas storage device when the first gas storage device needs to replenish dry gas in the future, the controller of the gas source system can be instructed to use the dry gas stored in the second gas storage device to replenish the first gas storage device, thereby improving the utilization rate of dry gas and effectively reducing the need for replenishment of dry gas in the gas source system.
