[0002] In the field of quantum computing, quantum chips have strict requirements on the temperature of their operating environment, and generally need to perform quantum computing at extremely low temperatures (such as 10 millikelvin). In related technologies, quantum chips are deployed inside a refrigerator (also called a dilution refrigerator), and the operating environment of the quantum chip is supported by regulating the temperature inside the refrigerator.

[0003] Currently, after the operator has written a script file for controlling the internal temperature of the refrigerator, the operator can load the script file on the refrigerator to control the internal temperature of the refrigerator, such as lowering or raising the internal temperature of the refrigerator.

[0060] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0061] In the related art, once the script file corresponding to the temperature control inside the refrigerator is determined, the temperature control inside the refrigerator will be strictly executed according to the script file. For example, when the thermodynamic temperature of the mixing chamber (MC) layer where the quantum chip in the refrigerator is located is 30mK (milliKelvin). After the operator writes the corresponding script file according to the temperature, the refrigerator can only reduce the temperature of the MC layer to 30mK by running the script file. If the temperature of the MC layer needs to be reduced to 10mK due to measurement and control requirements, the operator needs to rewrite the script file required for the internal temperature control of the refrigerator to achieve the requirement of reducing the temperature of the MC layer to 10mK.

[0062] Since the writing of the above-mentioned script files completely relies on the operators, this places high professional requirements on the operators, and the difficulty of rewriting the script files is relatively large. Therefore, the internal temperature control of the refrigerator in the related technology is difficult and requires high professionalism.

[0063] In order to solve the problems in the related art, the embodiment of the present application provides a refrigerator temperature control method. The method can be applied to a refrigerator temperature control system, which includes: an interactive device, a control device and a refrigerator.

[0064] like Figure 1 As shown, Figure 1 The first signaling diagram of the refrigerator temperature control method provided in the embodiment of the present application. The method includes the following steps.

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

[0066] Step S102: After receiving the data update instruction, the control device adjusts the temperature inside the refrigerator based on the first value.

[0067] In an optional embodiment, the control device may be a programmable logic controller (PLC) or a single chip microcomputer, etc. Here, the control device is not specifically limited.

[0068] In the above-mentioned refrigerator temperature control system, the interactive device and the control device can be deployed in the same electronic device or in different electronic devices. Here, the above-mentioned interactive device and control device are not specifically limited. For ease of understanding, the embodiment of the present application only takes the application scenario in which the interactive device and the control device are deployed in different electronic devices as an example for explanation, and does not serve any limiting role.

[0069] Through the method provided in the embodiment of the present application, when the user performs an update operation on one or more temperature control parameters required for the internal temperature control of the refrigerator, the interactive device can detect the update operation. At this time, the interactive device can send a data update instruction carrying the updated first value to the control device. The control device can control the internal temperature of the refrigerator based on the first value in the received data update instruction. Compared with the method of realizing the internal temperature control of the refrigerator by modifying the script file in the related art, the embodiment of the present application only needs to modify the temperature control parameters required for the temperature control process to realize the control 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 control process of the refrigerator.

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

[0071] The embodiments of the present application are described below through specific examples.

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

[0073] In an embodiment of the present application, the above-mentioned interactive device may include a display screen. A human-machine interaction interface is pre-configured in the above-mentioned interactive device. The human-machine interaction interface may be displayed on the display screen, and the human-machine interaction interface may include a start button, a parameter configuration button, a stop button, and a process display button for the internal temperature control process of the refrigerator. The human-machine interaction interface may be set according to user needs, etc., and the setting of the human-machine interaction interface in the interactive device is not specifically limited here.

[0074] In an optional embodiment, when the user triggers the parameter configuration button in the human-computer interaction interface by clicking on the display screen, a parameter configuration page will be displayed on the display screen. The parameter configuration page includes all temperature control parameters required for the internal temperature control process of the refrigerator. The user can perform data update operations on one or more parameters on the 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 (recorded as the first parameter) in the above parameter configuration page. When it is detected that 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, and the data update instruction includes the updated parameter value of the first parameter (recorded as the first value). At this time, the interactive device can send the data update instruction to the above control device.

[0076] The user may be the operator or other personnel, and the user is not specifically limited here.

[0077] In the embodiment of the present application, the internal temperature control process of the refrigerator can be divided into: a cooling control process and a heating control process. That is, the internal temperature control of the refrigerator in the embodiment of the present application can be a control for the cooling process or a control for the heating process.

[0078] In the above-mentioned temperature reduction control process and temperature increase control process, the temperature change process inside the refrigerator can be divided into multiple control stages.

[0079] For example, the control stages included in the temperature reduction control process corresponding to a known dilution refrigerator are sequentially expressed as: rough pumping stage, fine pumping stage, pulse pre-cooling (PPC) stage, and condensation stage. The control stages included in the temperature increase control process corresponding to the dilution refrigerator are sequentially expressed as: temperature increase determination stage, air collection stage, and 4K (open) stop stage.

[0080] For each control stage in the above-mentioned temperature increase control process and the temperature decrease control process, the temperature control parameters corresponding to the control stage are different. Specifically, as shown in Table 1 and Table 2, Table 1 shows the temperature control parameters corresponding to each control stage in the temperature decrease control process, and Table 2 shows the temperature control parameters corresponding to each control stage in the temperature increase control process.

[0081] Table 1

[0082]

[0083] Table 2

[0084]

[0085] In the above Tables 1 and 2, VC is a vacuum chamber (Vacuum Can), DR is a dilution refrigerator (Dilution Refrigerator), PT is a pulse tube refrigerator (Pulse Tube), which can also be called a helium (He) compressor, flow represents the helium flow rate, and P1, P2, P3, P4, P5, and P6 all represent pressures.

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

[0087] In the process of temperature reduction control, the first parameter may be any one or more temperature control parameters in Table 1. In the process of temperature increase control, the first parameter may be any one or more temperature control parameters in Table 2. Here, the first parameter and the number of the first parameters are not specifically limited.

[0088] In the above embodiment, only the above known dilution refrigerator is taken as an example to illustrate the control stages corresponding to the above temperature reduction control process and the temperature increase control process, as well as the temperature control parameters of each control stage. In addition, according to the difference of refrigerator, refrigerator temperature control principle and refrigerator internal temperature control process, the control stages corresponding to the above temperature reduction control process and the temperature increase control process, as well as the temperature control parameters of each control stage will also be different, which are not specifically limited here.

[0089] In an optional embodiment, in order to facilitate the control device to identify the first parameter corresponding to the first value in the data update instruction, the data update instruction may also include a parameter identifier corresponding to the first parameter. For ease of understanding, the first parameter is taken as the needle valve check time in Table 1. In addition to the updated time value corresponding to the needle valve check time, the data update instruction may also include a parameter identifier corresponding to the needle valve check time.

[0090] The parameter identifier corresponding to the above-mentioned first parameter can be composed of numbers, letters, special symbols, etc. Here, the parameter identifier corresponding to each temperature control parameter is not specifically limited.

[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 instruction to the control device in a manner specified by the MODBUS-TCP communication protocol standard.

[0092] In the embodiment of the present application, when the above-mentioned control device is a PLC, considering that the communication protocol of MODBUS-TCP is relatively simple and it is more convenient to communicate with the PLC, the use of MODBUS-TCP communication between the interactive device and the control device can effectively improve the convenience of information transmission. In addition, according to different control devices, different user needs and different actual application scenarios, different communication protocol standards can be used for communication between the interactive device and the control device, which is not specifically limited here.

[0093] 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 instruction to the control device, the control device receives the data update instruction. At this time, the control device can adjust the temperature inside the refrigerator based on the first value carried in the data update instruction.

[0095] In the embodiment of the present application, for different temperature control parameters, the control device will use different control methods to control the internal temperature of the refrigerator based on the parameter value corresponding to the temperature control parameter.

[0096] For ease of understanding, the dilution refrigerator corresponding to the above Table 1 and Table 2 is still taken as an example for explanation.

[0097] For the temperature control parameters related to the control valve in Tables 1 and 2 above (recorded as the first type of temperature control parameters), the control device can directly control the state of the solenoid valve corresponding to each control valve based on the parameter value corresponding to the first type of temperature control parameters, and realize gas circuit switching by switching the solenoid valve state, so that the control valve is switched to an open state or a closed state.

[0098] For the temperature control parameters related to the control device in Tables 1 and 2 above (recorded as second-category temperature control parameters), the control device can send instructions to the corresponding control device according to the parameter values ​​corresponding to the second-category temperature control parameters, so that the control device starts operating according to the received instructions.

[0099] For example, when the above-mentioned dilution refrigerator includes a control device such as a heater, the control device can send a heating instruction to the heater according to the parameter value corresponding to the second type of temperature control parameter corresponding to the heater, such as the 4K heating safety time in the above-mentioned Table 2. After the heating instruction, the heater can perform a heating operation within the time range corresponding to the 4K heating safety time according to the heating instruction.

[0100] In the above-mentioned known dilution refrigerator, the above-mentioned control valve can be a plug valve, a vacuum plate valve and other devices, and the above-mentioned control device can be a dry pump (DryPump), a heater, a PT and other devices. Here, the above-mentioned control valve and control device are not specifically limited.

[0101] In the embodiment of the present application, according to the difference of the above temperature control parameters, the control device will adopt different control methods to control the internal temperature of the refrigerator. Here, the process of the above control device controlling the internal temperature of the refrigerator is not described in detail.

[0102] In the above Figure 1 In the method shown, compared with the related art in which modifying the script file depends on the professionalism of the operator, the way in which the user modifies the parameters in the above-mentioned parameter configuration page in the embodiment of the present application reduces the difficulty of regulating the internal temperature of the refrigerator while having lower professional requirements for the user, thereby improving the flexibility and convenience of regulating the internal temperature of the refrigerator.

[0103] In an optional embodiment, according to the above Figure 1 The method shown in the embodiment of the present application also provides a method for controlling the temperature of a refrigerator. Figure 2 As shown, Figure 2 This is a second signaling diagram of the refrigerator temperature control method provided in the embodiment of the present application. Figure 2 In the method shown, the above step S102 is subdivided into the following steps, namely, step S1021 - step S1022.

[0104] Step S1021, the control device updates the parameter value corresponding to the first parameter in the second parameter stored in itself according to the first numerical value in the received data update instruction, and obtains the updated second parameter, where the second parameter is all the temperature control parameters required for the internal temperature control of the refrigerator.

[0105] In the embodiment of the present application, all temperature control parameters (recorded as second parameters) are pre-stored in the control device. For example, the control device pre-stores parameter values ​​and parameter identifiers corresponding to all temperature control parameters required for internal temperature control of the refrigerator.

[0106] After receiving the data update instruction sent by the above-mentioned interactive device, the control device can update the parameter value corresponding to the first parameter in the second parameter stored therein according to the first value carried by the data update instruction, that is, update the parameter value corresponding to the first parameter in the second parameter stored therein to the first value in the data update instruction. At this time, the control device will obtain the updated second parameter.

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

[0108] Step S1022: The control device adjusts the temperature inside the refrigerator based on the updated second parameter.

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

[0110] In case 1, when step S1021 occurs, the temperature control process inside the refrigerator has not yet started.

[0111] In case 2, when step S1021 occurs, the temperature control process inside the refrigerator has been completed.

[0112] In case three, when step S1021 occurs, the internal temperature control process of the refrigerator is still continuing, but the control phase corresponding to the first parameter has ended.

[0113] For ease of understanding, the above Table 1 is used as an example for explanation. It is now assumed that the above first parameter is the PPC time included in the PPC stage in Table 1. If the control device receives a data update instruction including the PPC time, and the internal temperature control process of the refrigerator has reached the Condense stage, the control device can determine that the control stage corresponding to the PPC time has ended.

[0114] In case 4, when step S1021 occurs, the temperature control process inside the refrigerator is still continuing, but the control phase corresponding to the first parameter has not yet started.

[0115] For ease of understanding, the first parameter is still taken as the PPC time. If the control device receives the data update instruction including the PPC time, the internal temperature control process of the refrigerator has only reached the fine extraction stage, then the control device can determine that the control stage corresponding to the first parameter has not started.

[0116] For the above situation 1 and situation 2, after the control device executes the above step S1021, since there is no need to adjust the internal temperature of the refrigerator, the control device will execute the above step S1022 only when it determines that the internal temperature of the refrigerator needs to be adjusted.

[0117] For the above situation three, after the control device executes the above step S1021, although the control device has updated the first parameter according to the data update instruction, since the current control stage is after the control stage corresponding to the first parameter, the temperature control parameter based on which the subsequent temperature control process is based has nothing to do with the updated first parameter. Therefore, in this cooling control process or heating control process, the first parameter in the updated second parameter is not effective. That is, the first parameter in the updated second parameter will take effect in the next cooling control process or heating control process.

[0118] For the above situation four, after the control device executes the above step S1021, since the regulation 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 regulation process or heating regulation process.

[0119] In the embodiment of the present application, according to the update time of the second parameter in the control device and the control stage of the internal temperature of the refrigerator at the update time, the effective time corresponding to the first parameter in the updated second parameter will also be different. Here, the effective time corresponding to the first parameter in the updated second parameter is not specifically limited.

[0120] Through the above steps S1021-S1022, after receiving the data update instruction, the control device updates the first parameter among the temperature control parameters stored therein based on the data update instruction, thereby avoiding data loss caused by the first value not being able to be immediately used in the temperature control process inside the refrigerator, and providing a guarantee for the fastest effectiveness of the first value.

[0121] In an embodiment of the present application, when the above-mentioned interactive device and the control device are deployed in different electronic devices, since the above-mentioned second parameter is pre-stored in the control device, during the internal temperature control process of the refrigerator, even if the interactive device fails, the control device can still control the internal temperature of the refrigerator based on the second parameter stored therein, thereby ensuring the stability of the internal temperature control of the refrigerator.

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

[0123] Step S1011: When the interactive device detects that the user performs an update operation on the first parameter in the parameter configuration page, the interactive device obtains an updated second value.

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

[0125] Step S1012: The interactive device matches the second value with a 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 (recorded as a preset value range) corresponding to the temperature control parameter is pre-set. 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] 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 instruction carrying the first value to the control device.

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

[0129] Through the above steps S1011 to 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 parameters and avoiding abnormal data from having an adverse effect on the subsequent temperature control process.

[0130] In an optional embodiment, according to the above Figure 3 The method shown in the embodiment of the present application also provides a method for controlling the temperature of a refrigerator. Figure 4 As shown, Figure 4 This is a fourth signaling diagram of the refrigerator temperature control method provided in the embodiment of the present application. Figure 4 The following step is added to the method shown, 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, through the above step S1012, if the second value is not within the corresponding preset value range, 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 may issue an abnormal alarm in the above parameter configuration page by means of a pop-up window, marking the second value in red, etc.

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

[0135] Through the above step S103, when the interactive device detects that the data updated by the user is abnormal data, it can issue an abnormal alarm in time, so that the user can find the abnormal data in time, ensure the accuracy of the updated temperature control parameters, and avoid the adverse effect of abnormal data on the subsequent temperature control process.

[0136] In an optional embodiment, according to the above Figure 1 The method shown in the embodiment of the present application also provides a method for controlling the temperature of a refrigerator. Figure 5 As shown, Figure 5 The fifth signaling diagram of the refrigerator temperature control method provided in the embodiment of the present application. The method includes the following steps.

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

[0138] Step S502: After receiving the data update instruction, the control device adjusts the temperature inside the refrigerator based on the first value.

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

[0140] Step S503: When the interactive device detects that the user triggers a start operation or a stop operation for regulating the internal temperature of the refrigerator, the interactive device sends a start instruction or a stop instruction to the control device.

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

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

[0143] In another optional embodiment, for the above-mentioned temperature reduction control process and the above-mentioned temperature increase control process, the start instructions and stop instructions corresponding to different control processes are different. For example, the start instruction for the temperature reduction control process may be a first start instruction, and the start instruction for the temperature increase control process may be a second start instruction, and the first start instruction is different from the second start instruction.

[0144] Step S504: The control device starts or stops regulating the internal temperature of the refrigerator based on the received start instruction or stop instruction.

[0145] In an optional embodiment, when the instruction received by the control device is the above-mentioned start instruction, the control device may obtain the temperature control parameters stored therein, and control the internal temperature of the refrigerator according to the temperature control parameters.

[0146] For example, in each control stage, 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 stage, and send corresponding instructions to the corresponding control device according to the parameter value of the second type of temperature control parameter corresponding to the control stage, so that the control device can operate based on the instruction.

[0147] In another optional embodiment, when the control device receives the above-mentioned stop instruction, the control device may stop regulating the internal temperature of the refrigerator according to the stop instruction.

[0148] In the embodiment of the present application, since the internal temperature control process of the refrigerator is carried out in stages, such as the various control stages shown in Tables 1 and 2 above, after the control device receives the above-mentioned stop instruction, it is necessary to perform a control stop operation according to the control stage (recorded as the current control stage) at which the internal temperature control of the refrigerator is currently reached.

[0149] For example, when the control device receives the above-mentioned stop instruction, if the current regulation 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 instructions to the control device related to the PPC stage.

[0150] In the embodiments of the present application, according to the different roles played by the control valves and control devices in the refrigerator in regulating the internal temperature of the refrigerator, the control device has different control principles for each control valve and control device, which results in different ways for the control device to start or stop the control valve and control device after receiving the start command or stop command. Here, the control method of the control device for the control valve and control device based on the above start command or stop command is not specifically described.

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

[0152] In the related art, when the refrigerator loads the above script file, it starts the cooling control process / heating control process of the internal temperature of the refrigerator until the internal temperature of the refrigerator reaches the target temperature, and the temperature control process ends. Compared with the related art, the interactive device can start or stop the internal temperature control process of the refrigerator in time according to user needs by detecting in real time whether the user triggers the start command or the stop command, thereby improving the flexibility of the internal temperature control of the refrigerator.

[0153] In an optional embodiment, the refrigerator may include a plurality of monitoring devices.

[0154] The monitoring device may be a device for monitoring parameters such as pressure, temperature, helium flow rate, etc. in a refrigerator, such as a vacuum gauge, a pressure gauge, a mass flow controller (MFC), etc. The monitoring device is not specifically limited here.

[0155] In an optional embodiment, according to the above Figure 1 The method shown in the embodiment of the present application also provides a method for controlling the temperature of a refrigerator. Figure 6 As shown, Figure 6 The sixth signaling diagram of the refrigerator temperature control method provided in the embodiment of the present application. The method comprises the following steps.

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

[0157] Step S602: After receiving the data update instruction, the control device adjusts the temperature inside the refrigerator based on the first value.

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

[0159] Step S603: each monitoring device obtains monitoring data at the current moment during the temperature change process inside the refrigerator.

[0160] In this step, during the temperature change process inside the refrigerator, that is, during the above-mentioned temperature reduction regulation process or temperature increase regulation process, each monitoring device in the refrigerator can perform data monitoring in real time to obtain monitoring data.

[0161] For ease of understanding, the refrigerator is taken as the above-mentioned known dilution refrigerator as an example, and the monitoring device is the above-mentioned pressure gauge for explanation.

[0162] In the cooling and regulating process shown in Table 1 above, the pressure gauges at different positions can monitor the pressure values ​​in the gas circuits in real time, such as the P1 value, P3 value, P4 value or P5 value in Table 1.

[0163] In an optional embodiment, the monitoring data may include the value monitored by the monitoring device (recorded as the monitoring value) and the monitoring time. In addition, the monitoring data may also include the device identification of the monitoring device, etc. Here, the monitoring data is not specifically limited.

[0164] In the embodiment of the present application, the monitoring values ​​in the above monitoring data are analog data (also called analog quantities).

[0165] Step S604: The control device obtains 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 above-mentioned refrigerator, the control device can obtain the monitoring data obtained by the real-time monitoring of the monitoring device, and 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 above-mentioned interactive device.

[0167] In the embodiment of the present application, since the monitoring value included in the monitoring data in the above step S703 is analog data, in order to facilitate the identification and processing of the later interactive device, 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. Here, the analog-to-digital conversion process is not described in detail.

[0168] Step S605 , after receiving the monitoring data corresponding to each monitoring device, the interactive device performs a visual display on the monitoring data corresponding to each monitoring device.

[0169] In an 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 above process display button by clicking or other operations in the above human-computer interaction interface, 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 Figure 7 To explain, Figure 7 A schematic diagram of a He flow rate display page provided in an embodiment of the present application. The MFC in the above refrigerator can monitor the He flow rate in the gas path in real time. The control device can obtain the He flow rate monitored in real time from the MFC and forward the He flow rate to the interactive device for caching.

[0171] When the user selects to display the Figure 7 In the He flow rate display page shown, the interactive device can obtain the He flow rate stored during 8:00-11:00 on January 1, and Figure 7 The He flow rate display page shown shows a curve of He flow rate changing with time.

[0172] exist Figure 7 In the He flow rate display page shown, the horizontal axis is the date and time data, and the vertical axis is the He flow rate data. Area 701 is the operation button area. For example, the user can zoom in on the He flow rate change curve over time by clicking button 702.

[0173] In the embodiment of the present application, after receiving the monitoring data corresponding to each monitoring device, the interactive device uses the following Figure 7 In addition to the visual display in the form of a curve graph shown, the visual display can also be performed in the form of a table, animation, etc. Here, the visual display method is not specifically limited.

[0174] Through the above steps S603-S605, the interactive device obtains the monitoring data monitored by each monitoring device in the refrigerator in real time through the control device, and visualizes the monitoring data, so that the user can understand the changes of relevant parameters during the internal temperature change of the refrigerator in real time, accurately grasp the progress of the internal temperature change of the refrigerator, and facilitate the user to adjust the internal temperature process of the refrigerator in real time according to their own needs.

[0175] Based on the same inventive concept, for the second parameter pre-stored in the above control device, the embodiment of the present application also provides a second parameter setting method. Figure 8 As shown, Figure 8 A signaling diagram of a second parameter setting method provided in an embodiment of the present application. The method comprises the following steps.

[0176] Step S801, when detecting a setting operation performed by a user on a second parameter, the interactive device sends a parameter setting instruction carrying a second value to the control device, where the second value is a parameter value of each temperature control parameter set for the second parameter.

[0177] In the embodiment of the present application, the user can set parameters for each temperature control parameter in the above parameter configuration page. When the interactive device detects that the user performs a setting operation on the second parameter in the parameter configuration page, it can obtain all the values ​​set by the user (recorded as the second value) and send a parameter setting instruction to the control device, and the parameter setting instruction carries the second value.

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

[0179] 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 refrigerator, which is convenient for the control device to update one or more parameters of the temperature control parameters in the later stage, and is convenient for the control device to control the internal temperature of the refrigerator based on the stored temperature control parameters.

[0182] Above Figure 8 The steps S801 and S802 shown can be executed before the steps S101 and S102, or can be executed at any time. Here, the execution time of the steps S801 and S802 is not specifically limited.

At this time, the interactive device can send a data update instruction carrying the updated first value to the control device.
