Description

Technical Field

[0001] This invention relates to the field of high-precision temperature control technology, and more specifically, to a high-precision temperature control method, system, electronic device, and computer storage medium based on multi-circulation media. Background Technology

[0002] TCU temperature control products refer to devices that use circulating media (water, ethylene glycol, etc.) to provide a constant temperature. They can control the temperature of their own water tank and transfer the temperature of the circulating media to the controlled object for heating or cooling, ultimately achieving control over the external object.

[0003] However, existing TCU temperature control products mostly use a single circulating medium for temperature control, but temperature is easily affected by various factors, and the upper and lower limits of the temperature control parameter curve of a single circulating medium are narrow, resulting in poor ability to cope with temperature fluctuations. This is not conducive to high-precision temperature control of the controlled object. Summary of the Invention

[0004] To solve at least one of the above-mentioned technical problems, the present invention employs multiple circulating media for high-precision temperature control, and specifically provides a high-precision temperature control method, system, electronic device, and computer storage medium based on multiple circulating media.

[0005] The first aspect of the present invention provides a high-precision temperature control method based on multiple circulating media, comprising the following steps:

[0006] During the first time period, the first set of circulating media is used to control the temperature of the temperature-controlled object, and it is determined whether the temperature control target of the second time period meets the preset conditions.

[0007] If so, the second set of circulating media is used to control the temperature of the object during the second time period; otherwise, the first set of circulating media is used to continue to control the temperature of the object during the second time period.

[0008] Furthermore, both the first group of circulating media and the second group of circulating media contain one circulating medium, or the first group of circulating media contains at least one circulating medium, and the second group of circulating media contains at least two circulating media.

[0009] Furthermore, the step of using a first set of circulating media to control the temperature of the temperature-controlled object during the first time period includes:

[0010] The first group of circulating media and the first media parameters corresponding to the first group of circulating media are determined based on the first temperature control target and the first temperature control environment.

[0011] The first group of circulating media is adjusted according to the first medium parameters to enter the corresponding temperature control pipeline in order to control the temperature of the object being controlled.

[0012] Furthermore, determining whether the temperature control target for the second time period meets the preset conditions includes:

[0013] Calculate the matching degree between the second temperature control target and the temperature control curve corresponding to the first medium parameter. If the matching degree is lower than the matching threshold, then perform matching calculation on other temperature control curves associated with the first group of circulating media according to the second temperature control target. If the matching calculation result is zero, then determine that the temperature control target of the second time period meets the preset conditions.

[0014] Furthermore, the determination of whether the temperature control target for the second time period meets the preset conditions also includes:

[0015] If the calculation result is not zero, a replacement temperature control curve will be selected from several other temperature control curves in the matching calculation result. The replacement temperature control curve will be used to determine the second medium parameter corresponding to the first group of circulating medium. The first group of circulating medium will be adjusted according to the second medium parameter to control the temperature of the temperature-controlled object.

[0016] Furthermore, the step of using a second set of circulating media to control the temperature of the temperature-controlled object during the second time period includes:

[0017] The second group of circulating media and the third media parameters corresponding to the second group of circulating media are determined based on the second temperature control target and the second temperature control environment.

[0018] The second group of circulating media is adjusted according to the third medium parameter to enter the corresponding temperature control pipeline in order to control the temperature of the object being controlled.

[0019] Further, the step of regulating the second group of circulating media into the corresponding temperature-controlled pipeline according to the third medium parameter includes:

[0020] The execution time of the third medium parameter is determined based on the matching degree of the temperature control curve corresponding to the second temperature control target and the first medium parameter, and the second group of circulating medium is adjusted to enter the corresponding temperature control pipeline according to the execution time.

[0021] A second aspect of the present invention provides a high-precision temperature control system based on multiple circulating media, comprising an acquisition module, a processing module, and a storage module; the processing module is connected to the acquisition module and the storage module.

[0022] The storage module is used to store executable computer program code;

[0023] The acquisition module is used to acquire temperature control target and temperature control environment data, and transmit them to the processing module;

[0024] The processing module is configured to execute the method described in the preceding one by invoking the executable computer program code in the storage module.

[0025] A third aspect of the present invention provides an electronic device comprising: a memory storing executable program code; a processor coupled to the memory; the processor invoking the executable program code stored in the memory to perform the method as described in any of the preceding claims.

[0026] A fourth aspect of the present invention provides a computer storage medium storing a computer program that, when executed by a processor, performs the method described in any of the preceding claims.

[0027] A fifth aspect of the invention provides a computer program product in which the computer program is executed, as described in any of the preceding methods.

[0028] The beneficial effects of this invention are as follows:

[0029] The present invention achieves the maintenance of high-precision temperature control capability by changing the circulating medium with stronger temperature control capability, so that the temperature-controlled object can maintain a high-precision target temperature under different temperature control targets and temperature control environments.

[0032] Figure 2 This is a schematic diagram of a high-precision temperature control system based on multiple circulating media disclosed in an embodiment of the present invention. Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0034] See Figure 1 The flowchart shown illustrates that this invention provides a high-precision temperature control method based on multiple circulating media, comprising the following steps:

[0035] During the first time period, the first set of circulating media is used to control the temperature of the temperature-controlled object, and it is determined whether the temperature control target of the second time period meets the preset conditions.

[0036] If so, the second set of circulating media is used to control the temperature of the object during the second time period; otherwise, the first set of circulating media is used to continue to control the temperature of the object during the second time period.

[0037] Because temperature control is affected by various factors, using a single circulating medium for temperature control is unreliable, especially in high-precision temperature control scenarios. The present invention initially uses a first set of circulating media to control the temperature of the controlled object. During this initial period, the target operating temperature or target operating environment of the controlled object does not change significantly, and the heat exchange capacity of the first set of circulating media is sufficient to provide a precise and stable temperature environment for the controlled object. However, if a significant change occurs in the target operating temperature or target operating environment during the second period, exceeding the temperature control capability of the first set of circulating media, the present invention replaces the first set with a second set of circulating media that has a higher temperature control capability, ensuring that the temperature control of the controlled object remains within the target range during the second period as well.

[0038] Therefore, the solution of the present invention achieves the maintenance of high-precision temperature control capability by changing the circulating medium with stronger temperature control capability, so that the temperature control object can maintain a high-precision target temperature under different temperature control targets and temperature control environments.

[0039] It should be noted that the circulating medium in this invention can be a cold medium and / or a hot medium. The medium flow pipeline can be composite, containing multiple sub-pipelines, each used for different circulating medium flows. Under different temperature control targets, the entry of circulating medium into each sub-pipeline, the specific flow rate, and the temperature of the circulating medium can be controlled, thereby realizing the aforementioned first group of circulating media and second group of circulating media.

[0040] Furthermore, both the first group of circulating media and the second group of circulating media contain one circulating medium, or the first group of circulating media contains at least one circulating medium, and the second group of circulating media contains at least two circulating media.

[0041] In this embodiment, the circulating medium in the present invention can be water, ethylene glycol, oil, or other mixed circulating media. The first and second sets of circulating media can each contain only one of the aforementioned types of circulating media. When there is a significant change in the temperature control target or temperature control environment (e.g., a sudden increase or decrease in temperature), the second set of circulating media, which has a higher temperature control capability (temperature adjustment range, temperature adjustment rate), is switched on, thereby ensuring that the temperature control object can still achieve high-precision tracking and control of the target temperature under the aforementioned preset conditions. Alternatively, both the first and second sets of circulating media can contain multiple circulating media, but the second set contains more types of circulating media. By using more circulating media to construct a "composite" circulating fluid, the temperature control capability is indirectly improved.

[0042] It should be noted that different types of circulating media have different specific heat capacities, which in turn lead to differences in their external heat exchange capabilities. This difference is reflected in the significant differences in their heating / cooling curves for the temperature-controlled object, primarily in the upper and lower limits of heating / cooling and the heating / cooling rates. This invention utilizes circulating media with different heat exchange capabilities to achieve adaptation to different levels of temperature control targets.

[0043] Furthermore, the step of using a first set of circulating media to control the temperature of the temperature-controlled object during the first time period includes:

[0044] The first group of circulating media and the first media parameters corresponding to the first group of circulating media are determined based on the first temperature control target and the first temperature control environment.

[0045] The first group of circulating media is adjusted according to the first medium parameters to enter the corresponding temperature control pipeline in order to control the temperature of the object being controlled.

[0046] In this embodiment, initially, a first temperature control target and a current first temperature control environment can be obtained for the temperature-controlled object. The first temperature control target includes a target temperature (or temperature curve) and the corresponding temperature fluctuation range. The target temperature curve can include the heating or cooling rate. The first temperature control environment mainly refers to the real-time temperature of the environment where the temperature-controlled object is located. Simultaneously, the temperature control capability curves of different types or groups of circulating media can be pre-determined. The temperature control capability curve is actually a set of multiple temperature control curves. Each temperature control curve corresponds to three factors: circulating media ID (each ID corresponds to a single circulating media or a combination of circulating media), the temperature, flow rate, and velocity of the circulating media (also corresponding to a single circulating media or a combination of circulating media), and the ambient temperature. Therefore, by matching and calculating the first temperature control target, the first temperature control environment, and each temperature control curve, the optimal first set of circulating media and its temperature control curve can be determined. Then, the temperature, flow rate, and velocity of the circulating media corresponding to this temperature control curve are used as the first media parameters. At this point, preliminary high-precision temperature control of the temperature-controlled object can be achieved. When the first group of circulating media is not a single medium, the first medium parameter actually includes the temperature, flow rate, and velocity of all circulating media, which will not be elaborated here.

[0047] It should be noted that the temperature control environment refers to the real-time temperature value or temperature fluctuation range of the environment in which the temperature control equipment is located. The closer the ambient temperature is to the temperature of the circulating medium, the easier it is for the circulating medium to achieve high-precision temperature control of the controlled object, and the faster the temperature control rate. Furthermore, the smaller the temperature fluctuation range of the environment, the easier it is for the circulating medium to achieve high-precision temperature control of the controlled object, and because the number of temperature control adjustments is lower, the temperature control accuracy will also be higher. Therefore, the present invention takes the above considerations into account regarding ambient temperature.

[0048] Furthermore, determining whether the temperature control target for the second time period meets the preset conditions includes:

[0049] Calculate the matching degree between the second temperature control target and the temperature control curve corresponding to the first medium parameter. If the matching degree is lower than the matching threshold, then perform matching calculation on other temperature control curves associated with the first group of circulating media according to the second temperature control target. If the matching calculation result is zero, then determine that the temperature control target of the second time period meets the preset conditions.

[0050] In this embodiment, the second temperature control target can also include a target temperature (or temperature curve) and the corresponding upper and lower ranges of temperature fluctuation, that is, it can include the same content as the first temperature control target. If the target temperature exceeds the upper or lower limit of the temperature control curve corresponding to the first medium parameter, or if the heating / cooling rate exceeds the upper or lower limit of the rate of the temperature control curve, it can be determined that the second temperature control target does not match the corresponding temperature control curve, that is, the second temperature control target exceeds the temperature control capability of the first group of circulating media under the first medium parameter. At this time, the other temperature control curves corresponding to the first group of circulating media are matched with the second temperature control target in the aforementioned manner. If no matching temperature control curve is found for the second temperature control target, it indicates that even if the temperature, flow rate, and velocity of the first group of circulating media are adjusted, the second temperature control target cannot be achieved, and it is determined that the temperature control target for the second time period meets the preset conditions.

[0051] It should be noted that the temperature control equipment communicates with the controlled object in real time, periodically, or as needed to obtain the planned temperature requirements for the controlled object's subsequent operation. From this, a second temperature control objective that the temperature control equipment needs to implement in the second time period can be analyzed. Of course, the second temperature control objective can also be provided to the temperature control equipment by the operator through various interactive methods.

[0052] Alternatively, the second temperature control target can also be determined based on the temperature control environment. For example, it may be predicted that the environment where the temperature-controlled object is located will be open during a second period (such as when a door is opened during product / equipment handling), causing the ambient temperature to rise / fall by a certain degree, which is detrimental to the normal operation of the temperature-controlled object. In this case, based on the degree rise / fall, the temperature control equipment is controlled to reduce / increase the heat exchange rate in a timely manner (usually a certain amount of time in advance) to maintain the temperature stability within the temperature-controlled environment.

[0053] Furthermore, the determination of whether the temperature control target for the second time period meets the preset conditions also includes:

[0054] If the calculation result is not zero, a replacement temperature control curve will be selected from several other temperature control curves in the matching calculation result. The replacement temperature control curve will be used to determine the second medium parameter corresponding to the first group of circulating medium. The first group of circulating medium will be adjusted according to the second medium parameter to control the temperature of the temperature-controlled object.

[0055] In this embodiment, when the aforementioned matching calculation hits the temperature control curve that matches the second temperature control target, it indicates that although the first medium parameter cannot achieve the control of the second temperature control target, the control of the second temperature control target can be achieved by replacing the first medium parameter of the first group of circulating medium with the second medium parameter. For example, inputting a higher temperature first group of circulating medium into the corresponding sub-pipe, increasing the supply flow rate of the first group of circulating medium, or reducing the flow rate of the first group of circulating medium.

[0056] Furthermore, the step of using a second set of circulating media to control the temperature of the temperature-controlled object during the second time period includes:

[0057] The second group of circulating media and the third media parameters corresponding to the second group of circulating media are determined based on the second temperature control target and the second temperature control environment.

[0058] The second group of circulating media is adjusted according to the third medium parameter to enter the corresponding temperature control pipeline in order to control the temperature of the object being controlled.

[0059] In this embodiment, following the aforementioned method for determining the circulating medium, a new optimal circulating medium and its third medium parameters can also be determined based on the new second temperature control target and the real-time second temperature control environment. By controlling each circulating medium in the second group of circulating mediums to enter the corresponding sub-pipes according to the third medium parameters, a circulating medium with higher temperature control capability can be used to achieve high-precision temperature control of the temperature-controlled object in the following second time period.

[0060] The second temperature control environment corresponds to the second time period. When it is predicted that the environment in the second time period will change and affect the temperature, the temperature or the degree of temperature change will be predicted and the predicted value will be used as the second temperature control environment. When it is predicted that the environment in the second time period will not change and affect the temperature, the first temperature control environment in the first time period (preferably the end of the first time period) will be used directly as the second temperature control environment.

[0061] Further, the step of regulating the second group of circulating media into the corresponding temperature-controlled pipeline according to the third medium parameter includes:

[0062] The execution time of the third medium parameter is determined based on the matching degree of the temperature control curve corresponding to the second temperature control target and the first medium parameter, and the second group of circulating medium is adjusted to enter the corresponding temperature control pipeline according to the execution time.

[0063] In this embodiment, temperature control requires time, meaning instantaneous response is not possible. Therefore, this invention adjusts the timing of the second group of circulating media control. Specifically, the lower the matching degree between the temperature control curve corresponding to the second temperature control target and the first media parameter, the greater the difference between the temperature control target faced by the new circulating media and that faced by the previous circulating media. This also increases the difficulty of temperature control during the switching period between the two circulating media. In this case, the earlier the execution time of the third media parameter is set compared to the boundary between the first and second time periods, the earlier the second group of circulating media is controlled to enter the corresponding sub-pipeline. Conversely, the earlier the execution time of the third media parameter is set compared to the boundary between the first and second time periods, the less the degree of early control of the second group of circulating media entering the corresponding sub-pipeline is reduced. This reduces the time of cross-execution between the first and second groups of circulating media, avoiding unexpected temperature control effects from the "new" circulating media (i.e., the first group of circulating media + the second group of circulating media), thus ensuring the achievement of high-precision temperature control targets.
