Description

Technical Field

[0001] The present application relates to the field of biomedical technology, and for example, to a temperature control method and device for an incubator, an incubator, and a computer-readable storage medium. Background Art

[0002] At present, in the field of biomedicine, there is a need for a device for in vitro culture of cells / tissues, such as an incubator, which usually requires a stable temperature and a stable gas concentration inside the box, so as to simulate an internal environment suitable for cultivation and growth. In order to ensure the stability of its internal temperature, the relevant technology proposes a method for controlling an incubator, including: obtaining the current inner tank temperature of the incubator through a temperature measuring device, and obtaining the current temperature variation between the current inner tank temperature and the set temperature; performing proportional integral differential PID fuzzy control according to the current temperature variation, and determining the current power value corresponding to each heating device in the incubator; and controlling the operation of the corresponding heating device according to the current power value.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0004] The relevant technology is mainly applied to air-jacketed incubators, which can improve the stability of the incubator temperature by directly heating the box body through a heating tube. However, for water-jacketed incubators, since the heating tube is used to heat the water jacket layer, and then transfer heat to the inner wall of the box through the heated water jacket layer, the overall temperature rise time is relatively long and the temperature lag is relatively large. When the incubator is powered off abnormally and then powered on again, the temperature inside the box will drop, and at this time the PID (Proportional Integral Derivative) control will clear the previously accumulated cumulative error value, causing the integral output value to basically return to zero, thereby causing the time required for the temperature inside the box to return to the target temperature to be greatly prolonged, seriously affecting the normal use of the water-jacketed incubator.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0006] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0007] The embodiments of the present disclosure provide a temperature control method, device, incubator, and computer-readable storage medium for an incubator, which can improve the actual heating effect of the heating device so that the temperature in the incubator can reach the target temperature more quickly, which is conducive to improving the actual operating effect of the incubator.

[0008] In some embodiments, the incubator is provided with a heating device; the control method comprises: when the incubator is powered on, continuously acquiring the real-time temperature in the incubator and determining the real-time temperature difference between the target temperature and the real-time temperature; when the real-time temperature in the incubator satisfies the abnormal temperature rise condition, amplifying the integral coefficient according to the real-time temperature difference; and performing PID control on the heating device based on the amplified integral coefficient so that the temperature in the incubator reaches the target temperature.

[0009] In some embodiments, the control device includes: a processor and a memory storing program instructions, and the processor is configured to execute the above-mentioned temperature control method for an incubator when running the program instructions.

[0010] In some embodiments, the incubator includes: a box body; a heating device installed on the box body; and the above-mentioned temperature control device for the incubator, electrically connected to the heating device.

[0011] In some embodiments, the computer-readable storage medium stores program instructions, and when the program instructions are executed, the computer is used to execute the above-mentioned temperature control method for the incubator.

[0012] The temperature control method, device, incubator, and computer-readable storage medium for an incubator provided in the embodiments of the present disclosure can achieve the following technical effects:

At the same time, the embodiment of the present disclosure can judge whether the abnormal temperature rise condition is met at this time.

[0028] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0030] Combination Figure 1 As shown, the embodiment of the present disclosure provides a temperature control method for an incubator, comprising:

[0031] S101, when the incubator is powered on, the control device continuously obtains the real-time temperature in the incubator and determines the real-time temperature difference between the target temperature and the real-time temperature.

[0032] S102, when the real-time temperature in the incubator meets the abnormal temperature rise condition, the control device amplifies the integral coefficient according to the real-time temperature difference.

[0033] S103, the control device performs PID control on the heating device based on the integral coefficient after the amplification process, so that the temperature in the incubator reaches the target temperature.

[0034] Using the temperature control method for an incubator provided by the embodiment of the present disclosure, during the heating process after the incubator is powered on, the real-time temperature in the incubator can be continuously detected, and the difference between the target temperature and the real-time temperature, that is, the corresponding real-time temperature difference at this time, can be determined, so as to judge whether the incubator has entered the temperature stabilization stage. At the same time, the embodiment of the present disclosure can judge whether the abnormal temperature rise condition is met at this time. If it is met, it indicates that the incubator has been in a state of slow temperature rise for a long time, and it is necessary to speed up the subsequent heating speed to ensure the normal operation of the incubator. At this time, the embodiment of the present disclosure can combine the current real-time temperature difference to appropriately amplify the integral coefficient in the PID algorithm to reasonably increase the actual output value of the integral term. On this basis, by performing PID control on the heating device, the embodiment of the present disclosure can improve the final control amount of the PID control, thereby improving the actual heating effect of the heating device, so that the temperature in the incubator can reach the target temperature faster, which is conducive to improving the actual operation effect of the incubator.

[0035] Optionally, the control device determines that the real-time temperature in the incubator satisfies the abnormal temperature rise condition in the following manner, including: when the real-time temperature in the incubator is between the preset temperature and the target temperature for a duration greater than or equal to a preset time, the control device determines that the abnormal temperature rise condition is satisfied.

[0036] In this way, when the incubator has not entered the temperature stabilization stage, the embodiment of the present disclosure can record the duration that the real-time temperature in the incubator is between the preset temperature and the target temperature. If the duration is greater than or equal to the preset duration, it indicates that the incubator has been in a state of slowly rising temperature for a long time. At this time, it is necessary to speed up the subsequent heating speed to ensure the normal operation of the incubator.

[0037] Optionally, the target temperature can be set in combination with the culture object in the incubator. Preferably, the target temperature can be set to 37°C to meet the environmental temperature required for most cell cultures. The target temperature can also be adjusted according to the actual needs of the user, and can also be set to any other reasonable value such as 36°C or 38°C.

[0038] Optionally, the preset temperature can be set in combination with the starting temperature of the integral term in the PID algorithm, which is slightly lower than the target temperature in the incubator. Preferably, the preset temperature can be set to 34°C. When the temperature in the incubator is greater than or equal to 34°C, the integral term in the PID algorithm participates in the control and starts recording the real-time accumulated temperature difference. The preset temperature can also be adjusted according to the actual needs of the user, and can also be set to any other reasonable value such as 33°C or 35°C.

[0039] Optionally, the preset time can be set in combination with the historical average time it takes for the temperature in the incubator to reach the target temperature from the preset temperature. Preferably, the preset time can be set to 2.5 hours, which is slightly longer than the standard time it takes for the temperature in the incubator to reach 37°C from 34°C, such as 2 hours. The preset time can also be adjusted according to the actual needs of the user, and can also be set to any other reasonable value such as 2 hours or 3 hours.

[0040] Optionally, combined Figure 2 As shown, the control device amplifies the integral coefficient according to the real-time temperature difference, including:

[0041] S201, the control device determines the target amplification ratio according to the real-time temperature difference.

[0042] S202, the control device calculates the product of the integral coefficient and the target amplification ratio to obtain the amplified integral coefficient.

[0043] In this way, when it is determined that the incubator meets the abnormal temperature rise condition, in order to speed up the subsequent temperature rise speed, the embodiment of the present disclosure can select a suitable target amplification ratio in combination with the current real-time temperature difference, and then amplify the original integral coefficient. By multiplying the original integral coefficient with the target amplification ratio, the embodiment of the present disclosure can obtain the amplified integral coefficient, so that the actual output value of the integral term can be reasonably increased, and then the final control amount of the PID control can be increased to improve the actual heating effect of the heating device, so that the temperature in the incubator can reach the target temperature faster, which is conducive to improving the actual operation effect of the incubator.

[0044] Among them, the target amplification ratio is positively correlated with the real-time temperature difference, and the target amplification ratio is greater than 1.

[0045] Optionally, the control device determines the target amplification ratio according to the real-time temperature difference, including: the control device matches the target amplification ratio corresponding to the real-time temperature difference from a preset association relationship according to the real-time temperature difference.

[0046] In this way, by constructing a preset correlation between the real-time temperature difference in the incubator and the target amplification ratio of the integral coefficient, the disclosed embodiment can match the appropriate target amplification ratio in combination with the current real-time temperature difference, thereby realizing a staged amplification of the integral coefficient. This can reasonably increase the actual output value of the integral term in the PID algorithm at the current stage, thereby appropriately increasing the final control amount of the PID control, so as to more accurately improve the actual heating effect of the heating device, so that the temperature in the incubator can reach the target temperature faster, which is conducive to improving the actual operation effect of the incubator.

[0047] Optionally, the preset association relationship includes one or more corresponding relationships between real-time temperature differences and target amplification ratios. For example, Table 1 shows a corresponding relationship between real-time temperature differences and target amplification ratios, as shown in the following table:

[0048] Table 1

[0049] Real-time temperature difference (℃) Target magnification ratio <![CDATA[(0,T1)]]> <![CDATA[a1]]> <![CDATA[[T1,T2)]]> <![CDATA[a2]]> <![CDATA[[T2,T3)]]> <![CDATA[a3]]> <![CDATA[[T3,T4)]]> <![CDATA[a4]]> <![CDATA[[T4,T max ]]]> <![CDATA[a5]]>

[0050] Among them, 0<T1<T2<T3<T4<T max , T max is the difference between the target temperature and the preset temperature, 1<a1<a2<a3<a4<a5.

[0051] Specifically, in some embodiments, T1 is 0.5°C, T2 is 1.0°C, T3 is 1.5°C, T4 is 2.0°C, T max is 3.0°C. Correspondingly, a1 is 1.1, a2 is 1.2, a3 is 1.3, a4 is 1.4, and a5 is 1.6.

[0052] In this way, when the real-time temperature difference in the incubator is large, the incubator is in the initial stage of heating, and the real-time cumulative temperature difference accumulated in the PID algorithm is relatively small, and the current heating speed in the incubator is relatively slow. Therefore, the embodiment of the present disclosure can set a relatively larger target amplification ratio to reasonably increase the actual output value of the integral term in the PID algorithm at the current stage, thereby facilitating the improvement of the final control amount of the PID control, so as to enhance the actual heating effect of the heating device, so that the temperature in the incubator can reach the target temperature faster, which is conducive to improving the actual operation effect of the incubator.

[0053] Optionally, combined Figure 3 As shown, the control device performs PID control on the heating device based on the integral coefficient after the amplification process, so that the temperature in the incubator reaches the target temperature, including:

[0054] S301, the control device determines the target operating parameters of the heating device according to the PID algorithm based on the integral coefficient after the amplification process.

[0055] S302, the control device controls the heating device to operate according to the target working parameters so that the temperature in the incubator reaches the target temperature.

[0056] In this way, after obtaining the integral coefficient after the amplification process, the embodiment of the present disclosure can use it to replace the original integral coefficient in the PID algorithm, and then determine the target operating parameters of the heating device based on the final control amount output at this time, thereby realizing precise regulation of the heating device. Therefore, the embodiment of the present disclosure can optimize the actual heating effect of the heating device, so that the temperature in the incubator can reach the target temperature faster, which is conducive to improving the actual operation effect of the incubator.

[0057] Optionally, the PID algorithm includes: U(t)=K P *e(t)+K I *∫e(τ)dτ+KD *de(t) / dt.

[0058] Among them, U(t) is the real-time output value, K P is the proportionality coefficient, K I is the integration coefficient, K D is the differential coefficient, e(t) is the real-time temperature difference, ∫e(τ)dτ is the real-time accumulated temperature difference, and de(t) / dt is the real-time temperature difference change rate.

[0059] In this way, when sufficient real-time cumulative temperature difference ∫(e(τ)dτ) is not accumulated, the integral coefficient K after amplification can be used. I 'To replace the original integral coefficient K in the PID algorithm I , thereby the actual output value of the integral term can be reasonably increased, and then the final control amount of the PID control can be increased, which is beneficial to improving the actual heating effect of the heating device, so that the temperature in the incubator can reach the target temperature faster, thereby improving the actual operation effect of the incubator.

[0060] Optionally, the target operating parameters include operating power and / or operating time. In this way, the operating state of the heating device can be reasonably regulated based on the above target operating parameters to produce a suitable heating effect, which is conducive to the temperature in the incubator reaching the target temperature faster.

[0061] Combination Figure 4 As shown, the embodiment of the present disclosure provides another temperature control method for an incubator, comprising:

[0062] S401, when the incubator is powered on, the control device continuously obtains the real-time temperature in the incubator and determines the real-time temperature difference between the target temperature and the real-time temperature.

[0063] S402, when the real-time temperature in the incubator meets the abnormal temperature rise condition, the control device amplifies the integral coefficient according to the real-time temperature difference.

[0064] S403: The control device performs PID control on the heating device based on the integral coefficient after the amplification process, so that the temperature in the incubator reaches the target temperature.

[0065] S404, when the real-time temperature in the incubator reaches the target temperature, the control device corrects the real-time accumulated temperature difference.

[0066] S405, the control device performs PID control on the heating device based on the integral coefficient and the corrected real-time accumulated temperature difference to stabilize the temperature in the incubator at the target temperature.

[0067] Using the temperature control method for an incubator provided by the embodiment of the present disclosure, during the heating process after the incubator is powered on, the real-time temperature in the incubator can be continuously detected, and the difference between the target temperature and the real-time temperature, that is, the corresponding real-time temperature difference at this time, can be determined, so as to judge whether the incubator has entered the temperature stabilization stage. At the same time, the embodiment of the present disclosure can judge whether the abnormal temperature rise condition is met at this time. If it is met, it indicates that the incubator has been in a state of slow temperature rise for a long time, and it is necessary to speed up the subsequent heating speed to ensure the normal operation of the incubator. At this time, the embodiment of the present disclosure can combine the current real-time temperature difference to appropriately amplify the integral coefficient in the PID algorithm to reasonably increase the actual output value of the integral term. On this basis, by performing PID control on the heating device, the embodiment of the present disclosure can improve the final control amount of the PID control, thereby improving the actual heating effect of the heating device, so that the temperature in the incubator can reach the target temperature faster, which is conducive to improving the actual operation effect of the incubator. In addition, when the real-time temperature in the incubator reaches the target temperature, the incubator officially enters the temperature stabilization stage. Considering that the integral coefficient after amplification is used in the PID algorithm at this time, if it is directly replaced with the original integral coefficient, the actual output value of the integral term will be small, and the final control amount of the PID control will also be relatively small. In order to avoid the temperature in the incubator from dropping at this time, the real-time accumulated temperature difference in the PID algorithm can be appropriately corrected to ensure that the integral term always maintains a reasonable actual output value. Then, the embodiment of the present disclosure can perform normal PID control on the heating device based on the original integral coefficient and the corrected real-time accumulated temperature difference, so that seamless connection can be achieved before and after reaching the target temperature, so that the temperature in the incubator can be better stabilized near the target temperature, which is conducive to maintaining the stability of the internal environment of the box.

[0068] Optionally, when the real-time temperature in the incubator reaches the target temperature, the control device corrects the real-time cumulative temperature difference, including: when the real-time temperature in the incubator reaches the target temperature, the control device records the current integral item output value; the control device calculates the quotient of the current integral item output value and the integral coefficient to obtain the corrected real-time cumulative temperature difference.

[0069] In this way, when the real-time temperature in the incubator reaches the target temperature, the current integral item output value can be recorded to avoid the temperature in the incubator from falling. For the purpose of keeping the integral item output value unchanged, the corrected real-time cumulative temperature difference can be obtained by calculating the quotient of the integral item output value and the original integral coefficient. Therefore, after the incubator officially enters the temperature stabilization stage, even if the original integral coefficient is used to replace the amplified integral coefficient, the actual output value of the integral item remains unchanged, thereby improving the stability of PID control. It is conducive to better stabilizing the temperature in the incubator near the target temperature to maintain the stability of the internal environment of the box.
