[0002] In the field of quantum computing, quantum chips have stringent temperature requirements for their operating environment, generally needing to perform quantum calculations at extremely low temperatures (such as 10 millikrell). Related technologies deploy quantum chips inside a refrigerator (also known as a dilution refrigerator), and the operating environment of the quantum chip is supported by controlling the temperature inside the refrigerator.

[0003] Currently, after operators have completed the script file for regulating the internal temperature of the refrigeration unit, they can load the script file onto the refrigeration unit to regulate the internal temperature, such as lowering or raising the internal temperature.

[0004] However, different types of tests are required during quantum chip testing. The operating environment needed for these different tests may vary. In such cases, operators need to rewrite the corresponding scripts and load them onto the refrigerator to adjust the testing environment, which significantly increases the difficulty of temperature control within the refrigerator.

[0046] Beneficial effects of the embodiments in this application:

[0047] The technical solution provided in this application embodiment allows an interactive device to detect an update operation when a user performs an update operation on one or more temperature control parameters required for regulating the internal temperature of a refrigerator. At this time, the interactive device can send a data update command carrying the updated first value to the control device. The control device can then regulate the internal temperature of the refrigerator based on the first value in the received data update command. Compared to related technologies that regulate the internal temperature of a refrigerator by modifying script files, this application embodiment only requires modification of the temperature control parameters required for the temperature regulation process to achieve temperature regulation of the refrigerator's internal temperature. The difficulty of modifying the parameters is significantly lower than the difficulty of modifying the script file, which greatly reduces the difficulty of the internal temperature regulation process of the refrigerator.

[0048] In addition, compared with the control methods in related technologies, the temperature control method provided in this application embodiment can modify only one or more temperature control parameters in the temperature control process, and does not necessarily need to modify all temperature control parameters. This effectively improves the flexibility of the internal temperature control process of the refrigeration unit.

[0049] Of course, implementing any product or method of this application does not necessarily require achieving all of the advantages described above at the same time. Attached Figure Description

[0060] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0061] In related technologies, once the script file for temperature control within a refrigerator is determined, the temperature control will be strictly executed according to that script file. For example, if the thermodynamic temperature of the mixing chamber (MC) layer containing the quantum chip in the refrigerator is 30 mK (mK), and the operator has written the corresponding script file based on this temperature, the refrigerator will only be able to lower the MC layer temperature to 30 mK by running that script file. If, due to measurement and control requirements, it is now necessary to lower the MC layer temperature to 10 mK, the operator will need to rewrite the script file required for temperature control within the refrigerator to achieve the desired temperature reduction.

[0062] Since the writing of the aforementioned script files depends entirely on the operators, which places high demands on their professional skills, and the rewriting of the script files is also relatively difficult, the related technology for controlling the internal temperature of the refrigeration unit is quite challenging and requires a high level of expertise.

[0063] To address the problems in related technologies, embodiments of this application provide a method for regulating the temperature of a refrigeration unit. This method can be applied to a refrigeration unit temperature regulation system, which includes: an interactive device, a control device, and a refrigeration unit.

[0064] like Figure 1 As shown, Figure 1 This is a first signaling diagram for a refrigeration unit temperature control method provided in an embodiment of this application. The method includes the following steps.

[0065] In step S101, when the interactive device detects that the user has performed an update operation on the first parameter, it sends a data update command carrying the first value to the control device; wherein, the first parameter is one or more temperature control parameters required for the internal temperature control of the refrigerator, and the first value is the parameter value of the updated first parameter.

[0066] In step S102, after receiving the data update instruction, the control device adjusts the temperature inside the refrigerator based on the first value.

[0067] In one optional embodiment, the control device described above can be a programmable logic controller (PLC) or a microcontroller, etc. No specific limitation is made to the control device described herein.

[0068] In the aforementioned refrigeration unit temperature control system, the interactive device and the control device can be deployed in the same electronic device or in different electronic devices. No specific limitations are imposed on the interactive device and control device described herein. For ease of understanding, this application embodiment only illustrates an application scenario where the interactive device and control device are deployed in different electronic devices, and does not constitute any limitation.

[0069] According to the method provided in this application, when a user performs an update operation on one or more temperature control parameters required for regulating the internal temperature of the refrigerator, the interactive device can detect the update operation. At this time, the interactive device can send a data update command carrying the updated first value to the control device. The control device can then regulate the internal temperature of the refrigerator based on the first value in the received data update command. Compared with the method in related technologies that regulates the internal temperature of the refrigerator by modifying script files, this application only requires modifying the temperature control parameters required for the temperature regulation process to achieve the regulation of the internal temperature of the refrigerator. The difficulty of modifying the parameters is significantly lower than the difficulty of modifying the script file, which greatly reduces the difficulty of the internal temperature regulation process of the refrigerator.

[0070] In addition, compared with the control methods in related technologies, the temperature control method provided in this application embodiment can modify only one or more temperature control parameters in the temperature control process, and does not necessarily need to modify all temperature control parameters. This effectively improves the flexibility of the internal temperature control process of the refrigeration unit.

[0071] The embodiments of this application will be described below through specific examples.

[0072] In step S101, when the interactive device detects that the user has performed an update operation on the first parameter, it sends a data update command carrying the first value to the control device; wherein, the first parameter is one or more temperature control parameters required for the internal temperature control of the refrigerator, and the first value is the parameter value of the updated first parameter.

[0073] In this embodiment, the interactive device may include a display screen. A human-machine interface is pre-configured in the interactive device. This human-machine interface can be displayed on the display screen and may include a start button, parameter configuration button, stop button, and process display button for the internal temperature control process of the refrigeration unit. The human-machine interface can be configured according to user needs, etc. Therefore, the specific configuration of the human-machine interface in the interactive device is not limited here.

[0074] In an optional embodiment, when a user triggers the parameter configuration button in the human-computer interaction interface by clicking or other means on the aforementioned display screen, the parameter configuration page will be displayed on the screen. This parameter configuration page includes all temperature control parameters required for the internal temperature control process of the refrigeration unit. The user can update data for one or more parameters on this parameter configuration page.

[0075] The interactive device can detect in real time whether the user triggers a data update operation for any one or more parameters (denoted as the first parameter) on the aforementioned parameter configuration page. When the user triggers a data update operation for the first parameter, the interactive device will generate a data update instruction corresponding to the data update operation. This data update instruction includes the updated parameter value of the first parameter (denoted as the first value). At this time, the interactive device can send this data update instruction to the aforementioned control device.

[0076] The users mentioned above can be the operators mentioned above, or other personnel. No specific limitations are made regarding the users mentioned above.

[0077] In this embodiment, the internal temperature control process of the refrigeration unit can be divided into a cooling control process and a heating control process. That is, in this embodiment, the internal temperature control of the refrigeration unit can be a control of the cooling process or a control of the heating process.

[0078] During the aforementioned cooling and heating control processes, the internal temperature change process of the refrigeration unit can be further divided into multiple control stages.

[0079] For example, the cooling control process of a known dilution refrigerator includes the following control stages in sequence: coarse extraction stage, fine extraction stage, pulse pre-cooling (PPC) stage, and condensation stage. The heating control process of the same dilution refrigerator includes the following control stages in sequence: heating determination stage, gas collection stage, and 4K (on) stop stage.

[0080] For each control stage in the above-mentioned heating and cooling control processes, the corresponding temperature control parameters are different. These are detailed in Tables 1 and 2. Table 1 shows the temperature control parameters for each control stage in the cooling control process, and Table 2 shows the temperature control parameters for each control stage in the heating control process.

[0081] Table 1

[0082]

[0083] Table 2

[0084]

[0085] In Tables 1 and 2 above, VC stands for Vacuum Can, DR stands for Dilution Refrigerator, PT stands for Pulse Tube (also known as Helium) Compressor, flow represents the helium flow rate, and P1, P2, P3, P4, P5, and P6 all represent pressures.

[0086] When the refrigerator in the above-mentioned temperature control system is the known dilution refrigerator, the parameter configuration page may include a first configuration page corresponding to the cooling control process and a second configuration page corresponding to the heating control process. The first configuration page may include each temperature control parameter in Table 1 above, and the second configuration page may include each temperature control parameter in Table 2 above.

[0087] During the cooling control process, the aforementioned first parameter can be any one or more temperature control parameters from Table 1. During the heating control process, the aforementioned first parameter can be any one or more temperature control parameters from Table 2. Here, no specific limitation is made on the aforementioned first parameter or the number of first parameters.

[0088] In the above embodiments, only the known dilution refrigerator is used as an example to explain the control stages corresponding to the cooling and heating control processes, as well as the temperature control parameters for each control stage. In addition, depending on the refrigerator, its temperature control principle, and the internal temperature control process, the control stages corresponding to the cooling and heating control processes, as well as the temperature control parameters for each control stage, will vary, and are not specifically limited here.

[0089] In an optional embodiment, to facilitate the control device's identification of the first parameter corresponding to the first value in the data update instruction, the data update instruction may further include a parameter identifier corresponding to the first parameter. For ease of understanding, the example given is the needle valve inspection time in Table 1. In addition to including the updated time value corresponding to the needle valve inspection time, the data update instruction may also include the parameter identifier corresponding to the needle valve inspection time.

[0090] The parameter identifier corresponding to the first parameter mentioned above can be composed of numbers, letters, special symbols, etc. Here, there is no specific limitation on the parameter identifier corresponding to each temperature control parameter.

[0091] In an optional embodiment, when the control device is the PLC, the interactive device and the control device can communicate according to MODBUS-TCP. MODBUS-TCP is a known Transmission Control Protocol (TCP) communication protocol standard. That is, the interactive device sends the data update instructions to the control device in accordance with the method specified by the MODBUS-TCP communication protocol standard.

[0092] In this embodiment, when the control device is a PLC, considering that the MODBUS-TCP communication protocol is relatively simple and more convenient for communication with the PLC, using MODBUS-TCP communication between the interactive device and the control device can effectively improve the convenience of information transmission. In addition, depending on the control device, user needs, and actual application scenarios, different communication protocol standards can be used between the interactive device and the control device for communication; no specific limitations are made here.

[0093] In step S102, after receiving the data update instruction, the control device adjusts the temperature inside the refrigerator based on the first value.

[0094] In this step, after the interactive device sends the data update command to the control device, the control device receives the data update command. At this time, the control device can adjust the internal temperature of the refrigerator based on the first value carried in the data update command.

[0095] In the embodiments of this application, the control device will use different control methods to regulate the internal temperature of the refrigerator based on the parameter value corresponding to the temperature control parameter, depending on the temperature control parameter.

[0096] For ease of understanding, we will still use the dilution refrigeration units corresponding to Tables 1 and 2 above as examples for explanation.

[0097] For the temperature control parameters related to the control valves in Tables 1 and 2 above (denoted as the first type of temperature control parameters), the control equipment can directly control the state of the solenoid valves corresponding to each control valve based on the parameter values ​​corresponding to the first type of temperature control parameters. By switching the state of the solenoid valves, the air path can be switched, thereby switching the control valves to the open or closed state.

[0098] For the temperature control parameters related to the controller in Tables 1 and 2 above (denoted as the second type of temperature control parameters), the control equipment can send instructions to the corresponding controller according to the parameter values ​​corresponding to the second type of temperature control parameters, so that the controller can start running according to the received instructions.

[0099] For example, when the aforementioned dilution refrigeration unit includes a heater as a control device, the control equipment can send a heating command to the heater based on the parameter value corresponding to the second type of temperature control parameter, such as the 4K heating safety time in Table 2 above. After receiving the heating command, the heater can perform heating operations within the time range corresponding to the 4K heating safety time.

[0100] In the aforementioned known dilution refrigeration machines, the control valves can be gate valves, vacuum plate valves, etc., and the control devices can be dry pumps, heaters, PTs, etc. No specific limitations are made here regarding the control valves and control devices.

[0101] In this embodiment, the control device will employ different control methods to regulate the internal temperature of the refrigerator based on the different temperature control parameters described above. The specific process by which the control device regulates the internal temperature of the refrigerator will not be described here.

[0102] In the above Figure 1 In the method shown, compared to the related technologies where modifying script files depends on the operator's expertise, the method in this application embodiment where the user modifies parameters on the above-mentioned parameter configuration page reduces the difficulty of temperature control inside the refrigeration unit while requiring less expertise from the user, thus improving the flexibility and convenience of temperature control inside the refrigeration unit.

[0103] In an optional embodiment, according to the above... Figure 1 The method shown in this application embodiment also provides a method for regulating the temperature of a refrigerator. For example... Figure 2 As shown, Figure 2 This is a second signaling diagram for the refrigeration unit temperature control method provided in the embodiments of this application. Figure 2 The method shown is further refined into the following steps: steps S1021-S1022.

[0104] In step S1021, the control device updates the parameter value corresponding to the first parameter in its stored second parameter according to the first value in the received data update instruction, and obtains the updated second parameter. The second parameter is all the temperature control parameters required for the internal temperature control of the refrigeration unit.

[0105] In this embodiment of the application, the control device pre-stores all temperature control parameters (denoted as the second parameter). For example, the control device pre-stores the parameter values ​​and parameter identifiers corresponding to all temperature control parameters required for temperature control inside the refrigeration unit.

[0106] After receiving the data update command from the aforementioned interactive device, the control device can update the parameter value corresponding to the first parameter in its stored second parameters according to the first value carried in the data update command. In other words, it updates the parameter value corresponding to the first parameter in its stored second parameters to the first value in the data update command. At this point, the control device will obtain the updated second parameter.

[0107] The second parameter mentioned above includes all temperature control parameters corresponding to the first parameter.

[0108] In step S1022, the control device adjusts the temperature inside the refrigerator based on the updated second parameter.

[0109] In this embodiment of the application, considering that the above step S1021 can occur at any time, the following situation may occur when the above step S1021 occurs.

[0110] In scenario one, when step S1021 occurs, the internal temperature control process of the refrigeration unit has not yet started.

[0111] In scenario two, when step S1021 occurs, the internal temperature control process of the refrigeration unit has already ended.

[0112] In scenario three, when step S1021 occurs, the internal temperature control process of the refrigeration unit is still ongoing, but the control phase corresponding to the first parameter mentioned above has already ended.

[0113] For ease of understanding, let's take Table 1 above as an example. Assume the first parameter is the PPC time included in the PPC stage of Table 1. If the control device receives a data update command including the PPC time, and the internal temperature control process of the refrigerator has already reached the Condense stage, then the control device can determine that the control stage corresponding to the PPC time has ended.

[0114] In scenario four, when step S1021 occurs, the internal temperature control process of the refrigeration unit is still ongoing, but the control phase corresponding to the first parameter mentioned above has not yet started.

[0115] For ease of understanding, we will continue to use the PPC time as the first parameter as an example. If the control device receives a data update command including the PPC time, and the internal temperature regulation process of the refrigerator has only reached the fine-tuning stage, then the control device can determine that the regulation stage corresponding to the first parameter has not yet started.

[0116] Regarding Situations 1 and 2 above, since the control device does not need to regulate the internal temperature of the refrigeration unit after executing step S1021, the control device will only execute step S1022 when it determines that the internal temperature of the refrigeration unit needs to be regulated.

[0117] Regarding scenario three above, although the control device updates the first parameter according to the data update instruction after executing step S1021, the current control phase is after the control phase corresponding to the first parameter. Therefore, the temperature control parameters used in subsequent temperature control processes are unrelated to the updated first parameter. Consequently, the first parameter in the updated second parameter does not take effect during the current cooling or heating control process. That is, the first parameter in the updated second parameter will take effect in the next cooling or heating control process.

[0118] Regarding the above situation four, after the control device executes the above step S1021, since the control phase corresponding to the first parameter has not yet started, when the control device executes the above step S1022, the first parameter in the updated second parameter will take effect in this cooling control process or heating control process.

[0119] In this embodiment, the effective time of the first parameter in the updated second parameter will vary depending on the update time of the second parameter in the control device and the adjustment stage of the internal temperature of the refrigerator at that update time. Here, no specific limitation is made on the effective time of the first parameter in the updated second parameter.

[0120] Through the above steps S1021-S1022, after receiving the data update instruction, the control device updates the first parameter in its stored temperature control parameters based on the data update instruction, avoiding the data loss caused by the first value not being able to be used immediately in the internal temperature control process of the refrigeration unit, and ensuring the fastest effective implementation of the first value.

[0121] In this embodiment of the application, when the interactive device and the control device are deployed in different electronic devices, since the control device has the second parameter stored in advance, even if the interactive device malfunctions during the internal temperature regulation of the refrigerator, the control device can still regulate the internal temperature of the refrigerator based on the second parameter stored in it, thus ensuring the stability of the internal temperature regulation of the refrigerator.

[0122] In an optional embodiment, according to the above... Figure 1 The method shown in this application embodiment also provides a method for regulating the temperature of a refrigerator. For example... Figure 3 As shown, Figure 3 This is a third signaling diagram for the refrigeration unit temperature control method provided in the embodiments of this application. Figure 3 In the method shown, the above step S101 is refined into the following steps, namely step S1011-step S1013.

[0123] In step S1011, when the interactive device detects that the user has performed an update operation on the first parameter in the parameter configuration page, it obtains the updated second value.

[0124] In an optional embodiment, when a user modifies the parameter value corresponding to the first parameter on the parameter configuration page, the interactive device will detect that the user has performed an update operation on the first parameter. At this time, the interactive device can obtain the modified parameter value as the updated second value.

[0125] In step S1012, the interactive device matches the second value with the preset value range corresponding to the first parameter.

[0126] In this step, for each temperature control parameter in the parameter configuration page, a valid value range (denoted as the preset value range) is pre-set for that temperature control parameter. After obtaining the second value, the interactive device can match the second value with the preset value range corresponding to the first parameter to determine whether the second value is within the corresponding preset value range.

[0127] In step S1013, when the second value is within the preset value range, the interactive device determines the second value as the first value after the first parameter is updated, and sends a data update command carrying the first value to the control device.

[0128] In this step, if the second value is within the corresponding preset value range through the above step S1012, the interactive device can determine that the second value is not abnormal data. At this time, the interactive device can determine that the second value is the updated first value corresponding to the value of the first parameter, and the interactive device can send a data update instruction carrying the second value to the control device.

[0129] Through the above steps S1011-S1013, after the user performs a data update operation on the first parameter, the interactive device automatically verifies the updated value, effectively ensuring the accuracy of the updated temperature control parameter and avoiding adverse effects of abnormal data on the subsequent temperature control process.

[0130] In an optional embodiment, according to the above... Figure 3 The method shown in this application embodiment also provides a method for regulating the temperature of a refrigerator. For example... Figure 4 As shown, Figure 4 This is a fourth signaling diagram for the refrigeration unit temperature control method provided in the embodiments of this application. Figure 4 The method shown has been augmented with the following step, namely step S103.

[0131] Step S103: When the second value is not within the preset value range, the interactive device issues an abnormal alarm for the second value.

[0132] In this step, if the second value is not within the corresponding preset value range according to step S1012, the interactive device can determine that the second value is abnormal data. At this time, the interactive device can issue an abnormal alarm for the second value.

[0133] In an optional embodiment, the interactive device can issue an anomaly warning in the above parameter configuration page by means of a pop-up window, marking the second value in red, etc.

[0134] Steps S103 and S1013 described above are steps executed by the interactive device when the matching result of the second value and the preset value range corresponding to its first parameter is different. Here, the execution of steps S103 and S1013 is not specifically limited.

[0135] Through the above step S103, when the interactive device detects that the updated data by the user is abnormal, it can issue an abnormal alarm in a timely manner, which makes it easier for the user to discover the abnormal data in time, ensures the accuracy of the updated temperature control parameters, and avoids the abnormal data from having an adverse effect on the subsequent temperature control process.

[0136] In an optional embodiment, according to the above... Figure 1 The method shown in this application embodiment also provides a method for regulating the temperature of a refrigerator. For example... Figure 5 As shown, Figure 5 This is a fifth signaling diagram for a refrigeration unit temperature control method provided in an embodiment of this application. The method includes the following steps.

[0137] In step S501, when the interactive device detects that the user has performed an update operation on the first parameter, it sends a data update command carrying the first value to the control device; wherein, the first parameter is one or more temperature control parameters required for the internal temperature control of the refrigerator, and the first value is the parameter value of the updated first parameter.

[0138] In step S502, after receiving the data update instruction, the control device adjusts the temperature inside the refrigerator based on the first value.

[0139] The steps S501-S502 described above are the same as the steps S101-S102 described above.

[0140] In step S503, when the interactive device detects that the user has triggered a start operation or a stop operation for the internal temperature control of the refrigerator, it sends a start command or a stop command to the control device.

[0141] In an optional embodiment, regarding the start button in the aforementioned human-computer interaction interface, when the user triggers the start button through clicking or other operations, the interaction device will detect that the user has initiated the start operation to start the internal temperature control process of the refrigerator. At this time, the interaction device will generate a start command for the internal temperature control of the refrigerator and forward the start command to the aforementioned control device.

[0142] In an optional embodiment, regarding the stop button in the aforementioned human-computer interaction interface, when the user triggers the stop button through clicking or other operations, the interaction device will detect that the user has triggered a stop operation to halt the internal temperature control process of the refrigerator. At this time, the interaction device will generate a stop command for the internal temperature control of the refrigerator and forward the stop command to the aforementioned control device.

[0143] In another optional embodiment, the start and stop commands for the aforementioned cooling and heating control processes are different. For example, the start command for the cooling control process can be a first start command, and the start command for the heating control process can be a second start command, wherein the first start command is different from the second start command.

[0144] In step S504, the control device starts or stops regulating the internal temperature of the refrigeration unit based on the received start or stop command.

[0145] In an optional embodiment, when the control device receives the aforementioned start command, the control device can obtain its stored temperature control parameters and adjust the internal temperature of the refrigerator according to the temperature control parameters.

[0146] For example, in each control phase, the control device can directly control the opening and closing of the corresponding control valve according to the parameter value of the first type of temperature control parameter corresponding to the control phase, and send a corresponding instruction to the corresponding controller according to the parameter value of the second type of temperature control parameter corresponding to the control phase, so that the controller can operate based on the instruction.

[0147] In another optional embodiment, when the control device receives the aforementioned stop command, the control device can stop regulating the internal temperature of the refrigerator according to the stop command.

[0148] In this embodiment of the application, since the internal temperature regulation process of the refrigerator is carried out in stages, as shown in Tables 1 and 2 above, after receiving the above-mentioned stop command, the control device needs to perform a regulation stop operation according to the current regulation stage of the internal temperature regulation of the refrigerator (denoted as the current regulation stage).

[0149] For example, when the control device receives the above-mentioned stop command, if the current control stage is the PPC stage shown in Table 1 above, the control device can control the control valve related to the PPC stage to close, and stop the operation of the corresponding control device by sending a command to the control device related to the PPC stage.

[0150] In this embodiment, the control principles of the control equipment for each control valve and control device differ depending on their respective roles in regulating the internal temperature of the refrigeration unit. This results in different ways the control equipment opens or stops the control valves and control devices after receiving start or stop commands. Here, the specific methods by which the control equipment regulates the control valves and control devices based on the aforementioned start or stop commands are not described.

[0151] exist Figure 5 In the illustrated embodiment, for a single temperature control process inside the refrigerator, when the instruction in step S503 is the aforementioned start instruction, steps S503-S504 can be executed before step S502; when the instruction in step S503 is the aforementioned stop instruction, steps S503-S504 can be executed after step S502. Here, the execution order between steps S503-S504 and steps S501-S502 is not specifically limited.

[0152] In related technologies, when the refrigeration unit loads the aforementioned script file, it initiates a cooling / heating control process for the internal temperature until the internal temperature reaches the target temperature, at which point the temperature control process ends. Compared to related technologies, the interactive device, by detecting in real time whether the user triggers a start or stop command, can promptly start or stop the internal temperature control process of the refrigeration unit according to user needs, thus improving the flexibility of internal temperature control.

[0153] In one optional embodiment, the refrigeration unit described above may include multiple monitoring devices.

[0154] The aforementioned monitoring devices can be devices in the refrigeration unit that monitor parameters such as pressure, temperature, and helium flow rate, such as vacuum gauges, pressure gauges, and mass flow controllers (MFC). No specific limitations are imposed on the aforementioned monitoring devices.

[0155] In an optional embodiment, according to the above... Figure 1 The method shown in this application embodiment also provides a method for regulating the temperature of a refrigerator. For example... Figure 6 As shown, Figure 6 This is a sixth signaling diagram for a refrigeration unit temperature control method provided in an embodiment of this application. The method includes the following steps.

[0156] In step S601, when the interactive device detects that the user has performed an update operation on the first parameter, it sends a data update command carrying the first value to the control device; wherein, the first parameter is one or more temperature control parameters required for the internal temperature control of the refrigerator, and the first value is the parameter value of the updated first parameter.

[0157] In step S602, after receiving the data update instruction, the control device adjusts the temperature inside the refrigerator based on the first value.

[0158] The steps S601-S602 described above are the same as the steps S101-S102 described above.

[0159] Step S603: Each monitoring device acquires monitoring data at the current moment during the temperature change inside the refrigerator.

[0160] In this step, during the temperature change inside the refrigerator, that is, during the aforementioned cooling or heating control process, each monitoring device in the refrigerator can perform real-time data monitoring and obtain monitoring data.

[0161] For ease of understanding, we will take the aforementioned known dilution refrigeration machine as an example and the pressure gauge mentioned above as a monitoring device for explanation.

[0162] During the cooling control process shown in Table 1 above, pressure gauges at different locations can monitor the pressure values ​​in their respective gas paths in real time, such as the P1, P3, P4, or P5 values ​​in Table 1.

[0163] In one optional embodiment, the monitoring data may include the values ​​detected by the monitoring device (denoted as monitoring values) and the monitoring time. In addition, the monitoring data may also include the device identifier of the monitoring device, etc. Here, no specific limitation is made on the aforementioned monitoring data.

[0164] In this embodiment of the application, the monitoring values ​​in the above monitoring data are simulated data (also known as analog quantities).

[0165] Step S604: The control device acquires the monitoring data corresponding to each monitoring device and sends the monitoring data corresponding to each monitoring device to the interactive device.

[0166] In this step, for each monitoring device in the refrigeration unit, the control device can acquire the monitoring data obtained by the monitoring device in real time, perform analog-to-digital conversion on the monitoring value in the monitoring data to obtain the monitoring data corresponding to the monitoring device, and send the monitoring data corresponding to the monitoring device to the interactive device.

[0167] In this embodiment, since the monitoring data in step S703 is analog data, to facilitate the identification and processing by the interactive device later, the control device can convert the analog data into digital data (digital quantity) through analog-to-digital conversion technology after obtaining the monitoring data from the monitoring device. The analog-to-digital conversion process will not be described in detail here.

[0168] In step S605, after receiving the monitoring data corresponding to each monitoring device, the interactive device visualizes the monitoring data corresponding to each monitoring device.

[0169] In one optional embodiment, after receiving the monitoring data corresponding to each monitoring device sent by the control device, the interactive device can store the monitoring data corresponding to each monitoring device. When the user triggers the process display button in the above-mentioned human-computer interaction interface by clicking or other operations, the interactive device can obtain the monitoring data corresponding to each monitoring device stored therein, and visualize the monitoring data in the form of graphs, tables, etc.

[0170] For ease of understanding, combined with Figure 7 To explain, Figure 7 This is a schematic diagram of a He flow rate display page provided in an embodiment of this application. The MFC in the aforementioned refrigerator can monitor the He flow rate in the gas path in real time. The control device can obtain the real-time monitored He flow rate from the MFC and forward the He flow rate to the interactive device for caching.

[0171] When a user selects to display on the screen of an interactive device through clicking or other operations... Figure 7 The He flow rate display page shown allows interactive devices to obtain the He flow rate stored on it for the period from 8:00 to 11:00 on January 1st, and to use the obtained data to... Figure 7 The He flow rate display page shows the curve of He flow rate changing over time.

[0172] exist Figure 7 In the He flow rate display page shown, the horizontal axis represents the date and time data, and the vertical axis represents the He flow rate data. Area 701 is the operation button area. For example, users can click button 702 to zoom in on the curve of He flow rate changing over time.

[0173] In this embodiment of the application, after receiving the monitoring data corresponding to each monitoring device, the interactive device, in addition to using methods such as... Figure 7 In addition to the curve graph shown, visualizations can also be presented in the form of tables, animations, etc. No specific limitations are placed on the visualization method here.

[0174] Through the above steps S603-S605, the interactive device obtains the monitoring data monitored in real time by each monitoring device in the refrigerator through the control device, and displays the monitoring data visually. The user can understand the changes of relevant parameters during the temperature change inside the refrigerator in real time, accurately grasp the progress of temperature change inside the refrigerator, and make it convenient for the user to adjust the temperature process inside the refrigerator in real time according to their own needs.

[0175] Based on the same inventive concept, and addressing the second parameter pre-stored in the aforementioned control device, embodiments of this application also provide a method for setting the second parameter. For example... Figure 8 As shown, Figure 8 A signaling diagram for a second parameter setting method provided in an embodiment of this application. The method includes the following steps.

[0176] In step S801, when the interactive device detects that the user has performed a setting operation on the second parameter, it sends a parameter setting instruction carrying a second value to the control device. The second value is the parameter value of each temperature control parameter set for the second parameter.

[0177] In this embodiment, the user can set parameters for each temperature control parameter on the parameter configuration page. When the interactive device detects that the user has set a second parameter on the parameter configuration page, it can obtain all the values ​​set by the user (denoted as the second value) and send a parameter setting command to the control device, which carries the second value.

[0178] In an optional embodiment, to facilitate the control device to accurately identify the second value corresponding to each temperature control parameter, the parameter setting instruction may carry the parameter identifier corresponding to the temperature control parameter.

[0179] In step S802, the control device stores the second value in the received parameter setting instruction.

[0180] In this step, after receiving the parameter setting instruction, the control device can store the second value in the parameter setting instruction. For example, the control device can store the second value according to the correspondence between the parameter identifier and the second value to obtain the second parameter pre-stored in the control device.

[0181] Through the above steps S801-S802, the control device can store the values ​​of all temperature control parameters required for the internal temperature control of the refrigeration unit, which facilitates the subsequent updating of one or more temperature control parameters by the control device, and facilitates the control device to control the internal temperature of the refrigeration unit based on the stored temperature control parameters.

[0182] The above Figure 8 Steps S801-S802 shown can be executed before steps S101 and S102, or at any time. Here, no specific limitation is made on the execution time of steps S801-S802.

[0183] Based on the same inventive concept, and according to the refrigeration unit temperature control method provided in the above embodiments of this application, this application also provides a refrigeration unit temperature control system. For example... Figure 9 As shown, Figure 9 This is a schematic diagram of a refrigeration temperature control system provided in an embodiment of this application. The system includes: an interactive device 901, a control device 902, and a refrigeration unit 903;

[0184] Interactive device 901 is used to send a data update command carrying a first value to control device 902 when it detects that the user has performed an update operation on the first parameter; wherein, the first parameter is one or more temperature control parameters required for internal temperature control of the refrigerator 903, and the first value is the parameter value of the updated first parameter.

[0185] The control device 902 is used to adjust the temperature inside the refrigerator 903 based on a first value after receiving a data update instruction.

[0186] Optionally, the aforementioned interactive device 901 can also be used to send a start command or stop command to the control device 902 when it detects that the user has triggered a start operation or stop operation for the internal temperature control of the refrigerator 903.

[0187] The aforementioned control device 902 can also be used to start or stop the regulation of the internal temperature of the refrigerator 903 based on the received start or stop command.

[0188] Optionally, the refrigeration unit 903 may include multiple monitoring devices;

[0189] The aforementioned monitoring device is used to acquire its own monitoring data at the current moment during the temperature change process inside the refrigerator 903;

[0190] The aforementioned control device 902 can also be used to acquire monitoring data corresponding to each monitoring device and send the monitoring data corresponding to each monitoring device to the interactive device 901;

[0191] The aforementioned interactive device 901 can also be used to visualize the monitoring data corresponding to each monitoring device after receiving the monitoring data corresponding to each monitoring device.

[0192] Optionally, the aforementioned interactive device 901 can be used to obtain the updated second value when it detects that the user has performed an update operation on the first parameter in the parameter configuration page; match the second value with the preset value range corresponding to the first parameter; when the second value is within the preset value range, determine the second value as the first value after the first parameter is updated, and send a data update command carrying the first value to the control device 902.

[0193] Optionally, the aforementioned interactive device 901 can also be used to issue an abnormal alarm for the second value when the second value is not within the preset value range.

[0194] Optionally, the aforementioned control device 902 can be used to update the parameter value corresponding to the first parameter in its stored second parameters according to the first value in the received data update instruction, so as to obtain the updated second parameter. The second parameter is all the temperature control parameters required for the internal temperature control of the refrigerator 903. Based on the updated second parameter, the internal temperature of the refrigerator 903 is controlled.

[0195] Optionally, the aforementioned interactive device 901 can also be used to send a parameter setting instruction carrying a second value to the control device 902 when it detects a setting operation performed by the user on the second parameter. The second value is the parameter value of each temperature control parameter set for the second parameter.

[0196] The aforementioned control device 902 can also be used to store the second value in the received parameter setting instruction.

[0197] The system provided in this application embodiment allows for the following operation: when a user performs an update operation on one or more temperature control parameters required for regulating the internal temperature of the refrigerator, the interactive device can detect the update operation. At this time, the interactive device can send a data update command carrying the updated first value to the control device. The control device can then regulate the internal temperature of the refrigerator based on the first value in the received data update command. Compared to related technologies that regulate the internal temperature of the refrigerator by modifying script files, this application embodiment only requires modification of the temperature control parameters required for the temperature regulation process to achieve temperature regulation of the refrigerator's internal temperature. The difficulty of modifying the parameters is significantly lower than the difficulty of modifying the script file, greatly reducing the difficulty of the internal temperature regulation process.

[0198] In addition, compared with the control methods in related technologies, the temperature control method provided in this application embodiment can modify only one or more temperature control parameters in the temperature control process, and does not necessarily need to modify all temperature control parameters. This effectively improves the flexibility of the internal temperature control process of the refrigeration unit.
