[0002] During the use of measurement equipment, a constant temperature chamber provides a stable temperature environment for the measurement equipment. The accuracy of its temperature control is crucial to the reliability of the measurement results. However, traditional constant temperature chamber temperature control methods often simply adjust the temperature based on the currently set required temperature value, without fully considering the dynamic changes in the ambient temperature outside the chamber and the specific temperature control requirements of different measurement equipment. This leads to unsatisfactory temperature control results. Moreover, because different measurement equipment requires different temperature control precisions, traditional temperature control methods often use the same temperature control strategy, which affects the efficiency of temperature regulation.

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0056] Example:

[0057] See also Figures 1 to 3 The present invention provides a temperature control method and system technical solution for a thermostat box of a measuring device: A temperature control method for a thermostat box of a measuring device, comprising the following steps:

[0058] S1: Obtain the real-time temperature control demand information of the target measurement device for the constant temperature box and the historical temperature control information of each measurement device for the constant temperature box. The real-time temperature control demand information includes the required temperature value, the real-time external temperature time series, and the initial temperature value. The historical temperature control information includes the historical initial temperature value set, the corresponding historical external temperature time series set, and the corresponding historical temperature control strategy.

[0059] The steps of obtaining the real-time temperature control requirement information of the target measuring device on the constant temperature box and the historical temperature control information of each measuring device on the constant temperature box include:

[0060] Determine a target constant temperature box corresponding to the target measurement device, and collect an initial temperature value of the target constant temperature box, wherein the initial temperature value includes an initial temperature value inside the box and an initial temperature value outside the box;

[0061] Collect the temperature values outside the constant temperature box in a continuous time to generate a real-time time series of the temperature outside the box, and record the real-time time series of the temperature outside the box and the initial temperature value as the real-time temperature control environment information;

[0062] Obtain the historical initial temperature value of the target constant temperature box corresponding to each measuring device and the corresponding historical box external temperature time series to form a historical initial temperature value set and a corresponding historical box external temperature time series set;

[0063] The historical initial temperature value set and the corresponding historical external temperature time series set are used as historical temperature control environment information, and the historical temperature control environment information and the corresponding historical temperature control strategy are used as historical temperature control information;

[0064] S2: A cloud server is configured at the control end of the thermostat corresponding to the target measurement device, and the real-time temperature control demand information and the historical temperature control information are stored in the cloud server. The association information between the real-time temperature control demand information and the historical temperature control information is set in the cloud server.

[0065] The steps of setting association information between real-time temperature control demand information and historical temperature control information in a cloud server include: setting sub-databases corresponding to the real-time temperature control demand information and the historical temperature control information in the cloud server, recording the sub-database storing the real-time temperature control demand information as a first sub-database, and recording the sub-database storing the historical temperature control information as a second sub-database; dividing the second sub-database into multiple storage areas according to the historical initial temperature value set; setting association information between the storage area and the first sub-database; and using the first sub-database, the storage area, and the association information between the first sub-database and the storage area as the association information between the real-time temperature control demand information and the historical temperature control information.

[0066] The steps of setting the association information between the storage area and the first sub-database include: setting information points for each storage area based on the historical initial temperature value set; setting multiple sub-storage areas for each storage area according to the historical outside-box temperature time series set, wherein each sub-storage area corresponds to a historical outside-box temperature time series; setting a first storage bit bar sequence in the first sub-database according to the real-time outside-box temperature time series; setting a second storage bit bar sequence for each sub-storage area according to the historical outside-box temperature time series to obtain multiple second storage bit bar sequences; setting the association information between the first storage bit bar sequence and the multiple second storage bit bar sequences according to the information points, and using the information points and the association information between the first storage bit bar sequence and the multiple second storage bit bar sequences as the association information between the storage area and the first sub-database.

[0067] It should be noted that the initial temperature value set includes two subsets, one is the initial temperature value set outside the box, and the other is the initial temperature value set inside the box. The initial temperature value outside the box corresponding to a measuring device is bound to the initial temperature value inside the box and stored on an information point, so as to be used for subsequent determination of the mapping point with the initial temperature value collected in real time. The real-time collected initial temperature value will be mapped on multiple information points, and the real-time collected initial temperature value inside the box and the initial temperature value outside the box are respectively corresponding to the historical initial temperature value outside the box and the historical initial temperature value inside the box on the information point. The mapping is successful, and the sub-storage area corresponding to the successfully mapped information point is used as the to-be-selected storage area. The synchronization chain between the to-be-selected storage area and the first sub-database is started, so as to select the corresponding data through the window for evaluating the similarity between the real-time temperature control environment information and the historical temperature control environment information, and then determine the temperature control strategy for the constant temperature box.

[0068] Specifically, a cloud server is first configured corresponding to the control end of the constant temperature box, and then the real-time collected temperature control demand information and historical temperature control information are stored in the cloud server, the real-time collected temperature control demand information is input on the control end, and then stored inside the cloud server, and the historical temperature control information is recorded in real time when the measuring equipment controls the temperature of the constant temperature box in the past, and stored inside the cloud server, and two sub-databases are set inside the cloud server, one for storing real-time data and the other for storing historical data. When the temperature control of the constant temperature box is completed, it is automatically stored in the sub-database for storing historical data, thereby updating the sub-database for storing historical data; multiple storage areas are set in the sub-database for storing historical data, each storage area corresponds to a historical initial temperature value inside the box, and multiple storage bit bars are set in the storage area, and the multiple storage bit bars correspond to multiple historical outside box temperature values in a historical outside box temperature time series, and are sorted in chronological order, and the storage bit bars are sorted in chronological order. The number of is consistent with the number of historical outside box temperature values, and the temperature at the first time point of the historical outside box temperature time series is consistent with the historical initial temperature value inside the box; thereby, the historical temperature control information and the real-time temperature control demand information are both stored in the cloud server; in the sub-database used to store the real-time temperature control demand information, it is necessary to collect the outside box temperature value in real time to generate the outside box temperature time series and transmit it to the corresponding sub-database in real time, establish the relationship between the outside box temperature time series and the historical outside box temperature time series, thereby completing the establishment of the association relationship between the two sub-databases, and the historical temperature control information corresponding to the real-time temperature control demand information can be selected through the two sub-databases, and the temperature control strategy corresponding to the historical temperature control information can be selected to control the temperature of the constant temperature box. The real-time collected temperature control demand information can timely reflect the current requirements for the constant temperature box temperature, and combined with the temperature control experience under similar conditions in the historical temperature control information, the temperature control strategy can be formulated more accurately, and the historical temperature control parameters can be adjusted with reference to improve the accuracy and effectiveness of temperature control.

[0069] The step of setting the association information between the first storage bit bar sequence and multiple second storage bit bar sequences according to the information point includes: setting a main window for the first storage bit bar sequence, setting sub-windows corresponding to the multiple second storage bit bar sequences respectively, and setting the same window parameters for the main window and the sub-windows, wherein the window parameters include the window moving step and the number of temperature values in the box outside temperature time series selected by each window after the movement; establishing synchronization chains between the main window and the multiple sub-windows respectively, and setting trigger conditions for the synchronization chains, marking the sub-windows corresponding to the synchronization chains that meet the trigger conditions to obtain marked sub-windows, wherein the trigger condition is that the initial temperature value on the first storage bit bar sequence is consistent with the historical initial temperature value corresponding to the information point on the second storage bit bar sequence; using the main window, sub-window, moving step, synchronization chain and the trigger condition corresponding to the synchronization chain as the association information between the first storage bit bar sequence and the multiple second storage bit bar sequences.

[0070] It should be noted that the association information between the first storage bit strip sequence and the plurality of second storage bit strip sequences is the association information between the real-time outside temperature time series and the historical outside temperature time series. The real-time outside temperature time series and the historical outside temperature time series are associated based on the association information, thereby being used for subsequent comparison between the real-time temperature control environment information and the historical temperature control environment information, thereby determining the historical temperature control strategy for the constant temperature box;

[0071] Specifically, the information point corresponding to the storage area where the real-time initial temperature value outside the box is located is determined as a mapping point, which can accurately locate the historical data storage area that is most relevant to the current real-time situation. When formulating a temperature control strategy, you can draw on the historical temperature control experience that is highly matched with the real-time conditions to improve the pertinence and accuracy of strategy formulation; determine the corresponding storage area based on the mapping point, and extract the historical outside box temperature sequence and the real-time outside box temperature time series in the storage area, set two windows corresponding to the two sequences respectively, each window corresponds to a sequence, and set the same moving step length for the main window and the sub-window respectively. The step length is used to determine the distance the window moves each time, thereby determining the moving position of each selected data, which is related to the size of the window. The main window sets multiple unit windows, and then each unit window corresponds to a temperature value. Based on multiple unit windows, multiple temperature values are selected. The number of unit windows set in the main window and the sub-window is the same. The step length is determined according to the real-time temperature acquisition frequency. The initial position of the main window and the sub-window The storage bit bars corresponding to the real-time initial temperature and the historical initial temperature are set, respectively. External temperature values from the external temperature time series are selected through a main window and a subwindow. One window corresponds to the real-time external temperature value, and the other window corresponds to the historical external temperature value. A synchronization chain is set between the two windows, and both windows are moved simultaneously. This allows the historical external temperature value corresponding to the real-time external temperature value to be selected by sliding the window. This is used to subsequently determine whether the control strategy for the constant temperature chamber can continue to use the temperature control strategy in the historical temperature control information. If so, it is continued. If not, the historical temperature control strategy is revised as a template to re-establish a viable temperature control strategy for the constant temperature chamber. Windows are set separately for the two sequences and moved simultaneously through a synchronization chain, enabling dynamic tracking of both real-time and historical external temperature values. This sliding window mechanism continuously selects historical external temperature values corresponding to the real-time situation over time, allowing the temperature control strategy to be dynamically adjusted based on changes in the real-time temperature, thereby improving the constant temperature chamber's adaptability to ambient temperature fluctuations. When the real-time outside temperature fluctuates abnormally, the sliding window mechanism quickly captures this change and promptly selects corresponding historical data for comparative analysis. If the historical temperature control strategy is found to no longer be applicable, the strategy can be revised immediately to prevent the incubator from losing control due to the inability to adapt to abnormal temperature changes.

[0072] S3: determining a historical external temperature time series corresponding to the real-time external temperature time series based on the correlation information, and determining a target temperature control strategy for the constant temperature box corresponding to the target measurement device based on the real-time external temperature time series and the historical external temperature time series;

[0073] The steps of determining the historical outside temperature time series corresponding to the real-time outside temperature time series based on the associated information include: obtaining real-time temperature control demand information and storing it in the first sub-database, obtaining historical temperature control information and storing it in the second sub-database; storing the historical outside temperature time series set and the corresponding historical initial temperature value set in the corresponding storage areas respectively; selecting the storage area corresponding to the real-time outside temperature time series from the second sub-database based on the trigger condition, extracting the historical outside temperature time series corresponding to the sub-storage area in the storage area and marking the sub-window corresponding to the sub-storage area to obtain a marked sub-window.

[0074] The steps of determining the target temperature control strategy of the constant temperature box corresponding to the target measurement device based on the real-time outside temperature time series and the historical outside temperature time series include: comparing the real-time outside temperature time series with the historical outside temperature time series, evaluating the similarity between the real-time outside temperature time series and each historical outside temperature time series, and determining the difference information between the real-time outside temperature time series and each historical outside temperature time series; extracting the historical temperature control strategy of the historical outside temperature time series corresponding to the highest similarity, and judging whether the highest similarity meets the preset similarity threshold, taking the historical outside temperature time series corresponding to the highest similarity that meets the preset similarity threshold as the target historical outside temperature time series, and taking the historical temperature control strategy corresponding to the target historical outside temperature time series as the target temperature control strategy; extracting the difference information between the outside temperature time series corresponding to the highest similarity that does not meet the preset similarity threshold and the historical outside temperature time series, revising the historical temperature control strategy corresponding to the difference information, and taking the revised historical temperature control strategy as the target temperature control strategy.

[0075] Specifically, the difference information refers to whether the difference between the real-time ambient temperature value and the historical ambient temperature value selected by the two unit windows belonging to the same position in the main window and the subwindow exceeds the preset difference threshold. If it exceeds the preset difference threshold, it means that there is difference information between the two. If it does not exceed the preset difference threshold, it means that there is no difference information between the two. The temperature difference is used to determine whether there is a difference. The historical outside temperature value corresponding to the difference with difference information is recorded as the difference temperature value, and the historical temperature control strategy corresponding to the difference temperature value stage is revised, and the real-time outside temperature value is used as the effective outside temperature in the temperature control strategy. The value is used to revise the control strategy corresponding to the temperature change stage in the historical temperature control strategy according to the temperature changes inside and outside the box. The specific revision process is to determine the impact of the outside temperature on the inside temperature according to the temperature changes inside and outside the constant temperature box of the target measurement device. For example, if the inside temperature is 19 degrees Celsius and the outside temperature is 23 degrees Celsius, when the outside temperature rises by 2 degrees Celsius, the inside temperature will rise by 1 degree Celsius with the outside if it is not regulated. At this time, the inside temperature needs to be regulated to drop by 1 degree Celsius to maintain the constant temperature inside the constant temperature box. The corresponding impact value at this time is 0.5, and the calculation formula of the impact value is: Among them, Δt represents the change in temperature inside the box, Δt′ represents the change in temperature outside the box, β represents other influencing factors, and K represents the influence value. The influence value is a proportional coefficient that represents the degree of direct influence of the outside temperature on the inside temperature. According to the influence value, when the historical outside temperature value is replaced by the real-time outside temperature value, it is determined that the adjustment strategy of the inside temperature value needs to be adjusted. For example, if the difference in temperature value is 1 degree Celsius, the impact of the historical outside temperature on the inside temperature is 1 degree Celsius. After being replaced by the real-time outside temperature, due to the difference between the two, when the difference is 1 degree Celsius, according to the influence value, the inside temperature needs to be reduced by 0.5 degrees Celsius. The corresponding calculation formula is, ΔT′=K×ΔT, where ΔT′ represents the adjustment amount of the inside temperature when the historical outside temperature value is replaced by the real-time outside temperature value, and ΔT represents the difference between the historical outside temperature value and the real-time outside temperature value. The control strategy is revised according to the adjustment amount. Revision refers to the adjustment of the control amount of the internal temperature of the constant temperature box in the historical control strategy according to the difference between the historical external temperature and the real-time external temperature. The control amount refers to the gap between the real-time internal temperature value and the required temperature value, which belongs to the target control amount. Since the change of the external temperature will cause the internal temperature to change accordingly, the adjustment amount refers to the difference between the target control amount and the actual control amount when there is difference information between the real-time external temperature value and the historical external temperature value; the revision of the historical temperature control strategy is completed as the target control strategy according to the impact value. When the temperature inside the box returns to the constant temperature value, continue to judge whether the subsequent changes of the real-time external temperature are the same as the historical external temperature sequence. If they are the same, continue to use the historical temperature control strategy as the target control strategy. If they are not the same, revise until the target control strategy is determined. The temperature control strategy refers to the single temperature control change corresponding to the temperature collection time.

[0076] The steps of comparing the real-time outside temperature time series with the historical outside temperature time series, evaluating the similarity between the real-time outside temperature time series and each historical outside temperature time series, and determining the difference information between the real-time outside temperature time series and each historical outside temperature time series include: extracting the outside temperature time series corresponding to the main window and the marked sub-window respectively, and synchronously moving the main window and the sub-window on the real-time outside temperature time series and the historical outside temperature time series according to the set window parameters; after each movement, selecting the same number of temperature values from the current positions of the main window and the sub-window respectively; calculating the difference between each pair of outside temperature values, performing a comprehensive calculation on all temperature differences, and evaluating the similarity between the two outside temperature time series; presetting a difference threshold, extracting the temperature value difference greater than the preset difference threshold as the abnormal difference, and taking each pair of outside temperature values corresponding to multiple pairs of consecutive abnormal differences as the difference information.

[0077] It should be noted that the temperature values selected from the main window and the sub-window after the same moving step, the same number of moves, and the same time point (or relative position) are regarded as a pair of temperature values;

[0078] Calculate the difference between each pair of outside temperature values, perform comprehensive calculation on all temperature differences, and evaluate the similarity between two outside temperature time series: record the real-time outside temperature time series corresponding to the main window as sequence A, and record the historical outside temperature time series corresponding to the sub-window as sequence B. Sequence A has n temperature values, recorded as A = {a1, a2, ... a n}, sequence B also has n temperature values (assuming that the two sequences have the same length so that a one-to-one comparison can be performed. When the two sequences have different lengths, since the initial temperature values of the temperature outside the box are the same, the initial temperature value is used as the starting point and the comparison starts from the starting point), denoted as B = {b1, b2, ... b n}, the difference between each pair of box and outside temperature values can be calculated by the following formula: ΔT i =a i -b i , i = 1, 2, ..., n, where ΔT i represents the difference between the i-th pair of outside temperature values, n represents the length of the temperature time series, that is, the number of temperature values, a i and b i : Represents the i-th temperature value in sequence A and B respectively. The comprehensive calculation can be done in many ways. For example, the corresponding formula using the average method is Among them, ΔT represents the average value of the temperature difference between the two sequences. Multiple average values are sorted according to the size of the average value, and the average value closest to 0 corresponds to the highest similarity between the two outside temperature sequences.

[0079] If the real-time situation is similar to the historical situation, the temperature control strategy from the historical temperature control information can continue to be used. This ensures the continuity and stability of the temperature control strategy and avoids the risks and costs associated with unnecessary policy adjustments. When the real-time situation differs significantly from the historical situation, the historical temperature control strategy can be revised as a template. While retaining historical experience, it can be optimized based on the real-time situation to develop a usable temperature control strategy that better meets current needs. Dynamic strategy development methods based on historical and real-time data can reduce trial and error costs and improve the efficiency of temperature control strategy development. At the same time, because the strategy is more closely aligned with the real-time situation, it can more effectively control the temperature of the constant temperature chamber, improve the quality and accuracy of temperature control, and ensure that the temperature inside the constant temperature chamber always remains within the set range.

[0080] S4: The temperature of the thermostat corresponding to the target strategy device is controlled according to the target temperature control strategy until the temperature inside the thermostat reaches the required temperature value.

[0081] A temperature control system for a thermostat of a measuring device, applied to the temperature control method for a thermostat of a measuring device as described in any one of the above, comprising:

[0082] The data acquisition module is used to obtain the real-time temperature control demand information of the target measurement device for the constant temperature box and the historical temperature control information of each measurement device for the constant temperature box. The real-time temperature control demand information includes the required temperature value, the real-time time series of the temperature outside the box, and the initial temperature value. The historical temperature control information includes the historical initial temperature value set, the corresponding historical time series set of the temperature outside the box, and the corresponding historical temperature control strategy.

[0083] A data association module is used to configure a cloud server at the control end of the thermostat corresponding to the target measurement device, store the real-time temperature control demand information and the historical temperature control information in the cloud server, and set the association information between the real-time temperature control demand information and the historical temperature control information in the cloud server;

[0084] a strategy determination module, configured to determine, based on the correlation information, a historical external temperature time series corresponding to the real-time external temperature time series, and determine a target temperature control strategy for the thermostat corresponding to the target measurement device based on the real-time external temperature time series and the historical external temperature time series;

[0085] The temperature control module is used to control the temperature of the thermostat corresponding to the target strategy device according to the target temperature control strategy until the temperature inside the thermostat reaches the required temperature value.

[0086] The present invention has multiple measuring devices corresponding to different required temperatures, respectively, and obtains the historical temperature of each measuring device, the environment at that time corresponding to the historical temperature, the process of environmental change, and the temperature control process corresponding to the environmental change process, and sets a corresponding sub-database. The sub-database includes an outside-box temperature time series, and establishes association information between the outside-box temperature time series and the real-time temperature time series, including a sliding window and a synchronization chain. The sliding window is used to extract the real-time temperature and the historical temperature within the same cycle (the same time period), and then determine the difference information. The length of the sliding window is set according to the temperature fluctuation threshold (for example, three or four consecutive temperatures are used to determine whether the temperature fluctuation is abnormal). The moving step size of the main window can be set according to the acquisition frequency of the real-time outside-box temperature, and when the real-time initial temperature is the same as the historical initial temperature, a step point is set on the two outside-box temperature time series corresponding to the acquisition time point, so as to determine the temperature fluctuation according to the moving step size. The position of the moving window is determined to determine the historical data that best fits the real-time situation, and the historical temperature control strategy corresponding to the historical data is used as the target temperature control strategy or can be revised into a preliminary control strategy for the target temperature control strategy; the environment at that time is compared with the current environment to evaluate the similarity between the environments. The control method when the environmental fluctuation is within the threshold adopts the historical control method, and the control method when the environmental fluctuation exceeds the threshold is re-formulated. By comparing the real-time box outside temperature time series with the historical box outside temperature time series, the historical control strategy that is most similar to the current situation can be found, so as to more accurately predict and control the temperature inside the box; when there is a difference between the real-time box outside temperature and the historical box outside temperature, the distinguishing information can be extracted and the historical control strategy can be revised to adapt to the new environmental conditions, which can make the control strategy more flexible and adaptable. By automatically revising the control strategy, the accuracy of temperature control inside the constant temperature box can be improved.
