Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of biological medicine, for example to a temperature control method and device for an incubator, an incubator and a computer readable storage medium. BACKGROUND

[0002] At present, in the field of biological medicine, a device for in vitro culture of cells / tissues, such as an incubator, is required, which generally requires that the inside of the box has stable temperature and stable gas concentration, so as to simulate an internal environment suitable for cultivation and growth. In order to ensure the stability of the internal temperature, the related technology proposes a method for controlling the incubator, comprising: obtaining the current inner tank temperature of the incubator by a temperature measuring device, and obtaining the current temperature difference between the current inner tank temperature and the set temperature; according to the current temperature difference, performing proportional integral derivative PID fuzzy control to determine the current power value of 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 at least the following problems exist in the related art:

[0004] The related technology is mainly applied to a gas jacket type incubator, which directly heats the box by a heating pipe, which can improve the stability of the temperature of the incubator. However, for a water jacket type incubator, since the heating pipe is used to heat the water jacket layer, and then the heated water jacket layer transmits heat to the inner wall of the box, the overall temperature rising time is relatively long, and the temperature hysteresis is relatively large. When the incubator is abnormally powered off and then powered on again, the temperature in the box will decrease, and at this time the PID (Proportional Integral Derivative) control will clear the accumulated error value accumulated before, resulting in that the integral term output value is basically zero, thereby causing the time required for the temperature in the box to return to the target temperature to be greatly lengthened, which seriously affects the normal use of the water jacket type incubator.

[0005] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0006] In order to have a basic understanding of some aspects of the disclosed embodiments, the following is a simple summary. The summary is not a general review, nor is it intended to determine the key / important constituent elements or delineate the scope of protection of these embodiments, but as a prelude to the detailed description below.

[0007] The temperature control method, device, incubator and computer readable storage medium provided by the embodiments of the present disclosure can improve the actual heating effect of the heating device, so that the temperature in the incubator can reach the target temperature faster, and the actual operation effect of the incubator can be improved.

[0008] In some embodiments, the incubator is provided with a heating device; the control method comprises: continuously acquiring a real-time temperature in the incubator when the incubator is powered on, and determining a real-time temperature difference between the target temperature and the real-time temperature; in the case that the real-time temperature in the incubator meets the temperature rise abnormal 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 comprises a processor and a memory storing program instructions, and the processor is configured to execute the temperature control method for the incubator when the program instructions are executed.

[0010] In some embodiments, the incubator comprises: a cabinet; a heating device installed on the cabinet; and the temperature control device for the incubator described above, which is electrically connected to the heating device.

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

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

[0013] During the temperature rising 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, i.e. the real-time temperature difference at this time, can be determined, so as to determine whether the incubator enters the temperature stable stage. At the same time, the present disclosure can determine whether the temperature rise abnormal condition is met at this time, and if so, it indicates that the incubator is in a slow temperature rising state for a long time, and the subsequent temperature rising speed needs to be accelerated to ensure the normal operation of the incubator. At this time, the present disclosure can appropriately amplify the integral coefficient in the PID algorithm in combination with the current real-time temperature difference, so as to reasonably improve the actual output value of the integral term.

[0030] In combination Figure 1 As shown, the embodiments of the present disclosure provide a temperature control method for an incubator, comprising:

[0031] S101, in the case of power-on of the incubator, the control device continuously acquires 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, in the case that the real-time temperature in the incubator meets the temperature rise abnormal 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 amplification processing, so as to make the temperature in the incubator reach the target temperature.

[0034] The temperature control method for the incubator provided by the embodiment of the present disclosure can continuously detect the real-time temperature in the incubator during the temperature rising process after the incubator is powered on, and determine the difference between the target temperature and the real-time temperature, i.e., the real-time temperature difference at this time, so as to determine whether the incubator enters the temperature stable stage. At the same time, the embodiment of the present disclosure can determine whether the temperature rise abnormal condition is met at this time. If the temperature rise abnormal condition is met, it indicates that the incubator is in a slow temperature rising state for a long time, and the subsequent temperature rising speed needs to be accelerated to ensure the normal operation of the incubator. At this time, the embodiment of the present disclosure can amplify the integral coefficient in the PID algorithm in combination with the current real-time temperature difference, so as to reasonably improve 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 quantity of the PID control, so as to 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 beneficial to improve the actual operation effect of the incubator.

[0035] Optionally, the control device determines that the real-time temperature in the incubator meets the temperature rise abnormal condition in the following manner: in the case that 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 duration, the control device determines that the temperature rise abnormal condition is met.

[0036] In this way, when the incubator does not enter the temperature stable stage, the embodiment of the present disclosure can record the duration for which 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 is in a slow temperature rising state for a long time, and the subsequent temperature rising speed needs to be accelerated 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 culture. The target temperature can also be adjusted according to the actual needs of the user, and can also be set to 36°C or 38°C or other arbitrary reasonable values.

[0038] Optionally, the preset temperature can be set in combination with the starting temperature of the integral term participating in control 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 control, and the real-time cumulative temperature difference starts to be recorded. The preset temperature can also be adjusted according to the actual needs of the user, and can also be set to 33°C or 35°C or other arbitrary reasonable values.

[0039] Optionally, the preset time length can be set in combination with a historical average time length for the temperature in the incubator to reach the target temperature from the preset temperature. Preferably, the preset time length can be set to 2.5 h, which is slightly greater than the standard time length, for example, 2 h, for the temperature in the incubator to reach 37℃ from 34℃. The preset time length can also be adjusted according to actual user needs, and can also be set to 2 h or 3 h or other arbitrary reasonable values.

[0040] Optionally, in combination with 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 a 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 judged that the incubator meets the temperature rise abnormality condition, in order to speed up the subsequent temperature rise speed, the embodiments 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 by the target amplification ratio, the embodiments of the present disclosure can obtain the amplified integral coefficient, so as to reasonably improve the actual output value of the integral term, and further improve the final control amount of the PID control, so as 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 beneficial to improve the actual operation effect of the incubator.

[0044] Wherein, the target amplification ratio and the real-time temperature difference are positively correlated, 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 the preset correlation relationship according to the real-time temperature difference.

[0046] In this way, by constructing the preset correlation relationship between the real-time temperature difference in the incubator and the target amplification ratio of the integral coefficient, the embodiments of the present disclosure can match a suitable target amplification ratio in combination with the current real-time temperature difference, so as to realize the staged amplification processing of the integral coefficient. Thereby, the actual output value of the integral term in the current stage PID algorithm can be reasonably improved, so as to appropriately improve 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 beneficial to improve the actual operation effect of the incubator.

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

[0048] Table 1

[0049] Real-time temperature difference (°C) Target magnification (0, T1) [a1] [[T1, T2)] [a2] [[T2, T3)] [a3] [[T3, T4)] [a4] [[T4, T max ]]]> [a5]

[0050] Wherein, 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℃, T2 is 1.0℃, T3 is 1.5℃, T4 is 2.0℃, and T max is 3.0℃. 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 temperature rise, and at this time, the real-time cumulative temperature difference accumulated in the PID algorithm is relatively small, and the current temperature rise 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 current stage PID algorithm, thereby facilitating the improvement of the final control quantity of the PID control to improve the actual heating effect of the heating device, so that the temperature in the incubator can reach the target temperature faster, and the actual operation effect of the incubator can be improved.

[0053] Optionally, as shown in Figure 3 , the control device performs PID control on the heating device based on the amplified integral coefficient to make the temperature in the incubator reach the target temperature, comprising:

[0054] S301, the control device determines the target working parameter of the heating device according to the PID algorithm based on the amplified integral coefficient.

[0055] S302, the control device controls the heating device to operate according to the target working parameter to make the temperature in the incubator reach the target temperature.

[0056] In this way, after obtaining the amplified integral coefficient, the embodiment of the present disclosure can replace the original integral coefficient in the PID algorithm, and then determine the target working parameter of the heating device based on the final control quantity output at this time, and then realize the accurate regulation and control 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, and the actual operation effect of the incubator can be improved.

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

[0058] Wherein, U(t) is the real-time output value, K P is the proportional coefficient, K I is the integral coefficient, K D is the differential coefficient, e(t) is the real-time temperature difference, ∫e(τ)dτ is the real-time cumulative temperature difference, and de(t) / dt is the real-time temperature difference rate.

[0059] In this way, when the real-time cumulative temperature difference ∫(e(τ)dτ) fails to accumulate enough, the integral coefficient K I after amplification processing can be used to replace the original integral coefficient K I in the PID algorithm, so that the actual output value of the integral term can be reasonably improved, and the final control quantity of the PID control can be improved, which is conducive to improving the actual heating effect of the heating device, so that the temperature in the incubator can reach the target temperature faster, and the actual operation effect of the incubator can be improved.

[0060] Optionally, the target working parameter includes the running power and / or the running time. In this way, the running state of the heating device can be reasonably controlled based on the target working parameter, so that the heating device can produce a suitable heating effect, and the temperature in the incubator can reach the target temperature faster.

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

[0062] S401, in the case that the incubator is powered on, the control device continuously acquires 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, in the case that the real-time temperature in the incubator meets the temperature rise abnormality 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 amplification processing, so that the temperature in the incubator reaches the target temperature.

[0065] S404, in the case that the real-time temperature in the incubator reaches the target temperature, the control device corrects the real-time cumulative temperature difference.

[0066] S405, the control device performs PID control on the heating device based on the integral coefficient and the corrected real-time cumulative temperature difference, so that the temperature in the incubator is stabilized at the target temperature.

[0067] The temperature control method for the incubator provided by the embodiment of the present disclosure can continuously detect the real-time temperature in the incubator during the temperature rising process after the incubator is powered on, and determine the difference between the target temperature and the real-time temperature, that is, the real-time temperature difference at this time, so as to determine whether the incubator enters the temperature stable stage. At the same time, the embodiment of the present disclosure can determine whether the temperature rise abnormal condition is met at this time. If it is met, it indicates that the incubator is in a slow temperature rising state for a long time, and the subsequent temperature rising speed needs to be accelerated to ensure the normal operation of the incubator. At this time, the embodiment of the present disclosure can appropriately amplify the integral coefficient in the PID algorithm in combination with the current real-time temperature difference, so as to reasonably improve 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 quantity of the PID control, so as 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 beneficial to improve the actual operation effect of the incubator. In addition, when the real-time temperature in the incubator reaches the target temperature, the incubator formally enters the temperature stable stage. Considering that the integral coefficient in the PID algorithm at this time is the integral coefficient after amplification processing, if it is directly replaced by the originally planned integral coefficient, the actual output value of the integral term will be smaller, and the final control quantity of the PID control will also be relatively smaller. To avoid the temperature drop in the incubator at this time, the real-time cumulative 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 originally planned integral coefficient and the corrected real-time cumulative temperature difference, so as to realize seamless connection before and after reaching the target temperature, so that the temperature in the incubator can be better stabilized near the target temperature, which is beneficial to maintain the stable internal environment of the incubator.

[0068] Optionally, in the case that the real-time temperature in the incubator reaches the target temperature, the control device corrects the real-time cumulative temperature difference, including: in the case that the real-time temperature in the incubator reaches the target temperature, the control device records the current integral term output value; the control device calculates the quotient value of the current integral term 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 term output value can be recorded to avoid the temperature drop in the incubator. Based on the purpose of keeping the integral term output value unchanged, the corrected real-time cumulative temperature difference can be obtained by calculating the quotient value of the integral term output value and the originally planned integral coefficient. Therefore, after the incubator formally enters the temperature stable stage, even if the integral coefficient after amplification processing is replaced by the originally planned integral coefficient, the actual output value of the integral term always remains unchanged, thereby improving the stability of the PID control. It is beneficial to better stabilize the temperature in the incubator near the target temperature to maintain the stable internal environment of the incubator.
