[0074] 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. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

It should also be understood that terms such as those defined in common dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined in this manner in the embodiments of the present invention.

Words such as "one", "an" or "the" do not indicate a quantity limitation, but rather indicate the existence of at least one. Similarly, words such as "include" or "comprise" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

The steps before or after the method of the embodiment of the present invention do not necessarily have to be performed in exact order. On the contrary, the various steps may be processed in reverse order or simultaneously. At the same time, other operations may be added to these processes, or one or more steps may be removed from these processes.

[0077] In addition, the functional modules in the various embodiments of the present invention may be integrated together to form an independent part, or each module may exist independently, or two or more modules may be integrated to form an independent part.

[0078] Figure 1 A flow chart of a method for temperature range control and intelligent door opening management of an incubator according to the present invention is shown.

[0079] like Figure 1 As shown, the first aspect of the present invention discloses a method for temperature range control and intelligent door opening management of an incubator, the method comprising:

[0080] S102, obtaining first temperature information;

[0081] S104, obtaining second temperature information according to the first temperature information;

[0082] S106, acquire the cabinet door state information;

[0083] S108, adjust the heating parameter and the air volume parameter according to the second temperature information and the cabinet door state information;

[0084] S110, judge whether the cabinet door state is in the cabinet door closed state;

[0085] S112, if yes, set the cabinet door control authority according to the second temperature information;

[0086] S114, if no, acquire the first time information;

[0087] S116, adjust the heating parameter information or send a first warning instruction according to the first time information and the second temperature information.

[0088] It should be noted that the first temperature information is the temperature value measured by each temperature sensor in the temperature box; the second temperature information is the temperature value of the temperature box; the cabinet door state information is the opening and closing state of the cabinet door of the temperature box, including the cabinet door closed state and the cabinet door opened state; the heating parameter is the parameter of the heating power of the heater for controlling the temperature box; the air volume parameter is the parameter of the air volume of the fan for controlling the temperature box; and the first time information is the duration of the cabinet door in the cabinet door opened state.

[0089] In this embodiment, the temperature measurements of each temperature sensor within the incubator are first verified, including but not limited to amplitude limit and rate-of-change checks, to determine if the temperature measurements are abnormal. Based on the temperature measurements of several temperature sensors that fall within normal values, the incubator temperature value is calculated using a predefined filtering and averaging algorithm. Next, an upper airflow threshold is set based on the door status to prevent excessively high airflow when the door is open, mitigating safety hazards. The temperature uniformity within the incubator is analyzed based on the incubator temperature values ​​and the recorded values ​​of each temperature sensor. When temperature differences between locations within the incubator are large, a high airflow rate is used to achieve uniform temperature distribution. When temperature differences between locations within the incubator are small, a reduced airflow rate is used to minimize heat loss within the incubator. By calculating the difference between the incubator temperature value and the target temperature, the heating unit's heating output setting is adjusted based on this temperature difference according to a predefined control variable calculation strategy. This real-time feedback adjustment improves the efficiency and stability of temperature control and limits the fluctuation of the incubator temperature. Finally, when it is determined that the thermostat is in the door-closed state, the door-opening permission flag is set according to the thermostat temperature value, so as to prohibit the thermostat door from being opened when the temperature is too high, thereby reducing safety hazards. When it is determined that the thermostat is in the door-open state, there is heat exchange between the inside of the thermostat and the external environment, which is likely to affect the thermostat temperature value. By adjusting the control quantity coefficient of the control quantity calculation strategy, the sensitivity of temperature changes is increased, so that when the thermostat temperature changes, the heating parameters can be adjusted more quickly, thereby reducing the fluctuation range of the thermostat temperature. In addition, the length of time the thermostat is in the door-open state is recorded. If the length of time is too long, it means that the thermostat is at risk of being difficult to maintain temperature due to the door being open for a long time, or the operator has performed an erroneous operation of failing to close the door successfully. At this time, a first warning instruction is sent to provide a warning message to the thermostat operator.

[0090] Figure 2 A flow chart of verifying the first temperature information provided by an embodiment of the present invention is shown.

[0091] According to an embodiment of the present invention, Figure 2 As shown, the second temperature information is obtained according to the first temperature information, specifically:

[0092] S202, obtaining first temperature information according to a preset first time period;

[0093] S204, determining whether the first temperature information is within a preset first temperature range;

[0094] S206, if yes, obtain change rate information according to the first temperature information;

[0095] S208, determining whether the change rate information is less than a preset change rate threshold;

[0096] S210, if yes, obtaining third temperature information according to the first temperature information;

[0097] S212, obtaining the second temperature information according to the third temperature information and a preset filtering strategy.

[0098] It should be noted that the third temperature information is a data processing value of the first temperature information, that is, an arithmetic process value of the measured value of each temperature sensor. In the embodiment, the temperature measured value output by the temperature sensor is analyzed in amplitude and change rate to determine whether the first temperature information is an abnormal interference value. First, at least two first temperature information are collected according to a set time period for each temperature sensor. Second, it is determined whether the first temperature information is within a set temperature range, if yes, it indicates that the first temperature information belongs to a normal value; wherein the temperature range is determined by a target temperature and a room temperature, in actual application, if the set target temperature value is 37℃ and the room temperature is 25℃, the set range is set to 15℃ to 47℃. Then, the change amplitude of the measured temperature value of each temperature sensor is calculated according to several first temperature information, and then converted into a change rate, when the change rate is less than a preset change rate threshold, it indicates that the first temperature information belongs to a normal value. Finally, the arithmetic mean value is calculated according to the collected several first temperature information, and the third temperature information is obtained as the arithmetic process value of the second temperature information.

[0099] According to the embodiment of the present application, the second temperature information is obtained according to the third temperature information and a preset filtering strategy, specifically:

[0100] According to a preset number, the fourth temperature information is obtained;

[0101] According to the third temperature information and the fourth temperature information, the third temperature information is updated and recorded according to a preset filtering strategy;

[0102] Obtaining first number information;

[0103] According to the first number information and the third temperature information, a first temperature sequence is obtained according to a preset arrangement order;

[0104] According to the first number information, the temperature value in the first temperature sequence is extracted, and the second temperature information is obtained according to a preset mean algorithm.

[0105] It should be noted that the fourth temperature information is the stored value of the third temperature information after data processing, namely, the temperature detection record values ​​of each temperature sensor in the memory; the first quantity information is the number of temperature sensors installed in the incubator to measure the internal temperature of the incubator. In this embodiment, the temperature records of at least two temperature sensors, namely, the fourth temperature information, are obtained and combined with the third temperature information to update the third temperature information according to a preset filtering algorithm. The filtering algorithm includes but is not limited to a Butterworth low-pass filter algorithm, a Chebyshev low-pass filter algorithm, a Kalman filter algorithm, etc., to further reduce the interference of detection noise and improve temperature accuracy. Then, according to the number of temperature sensors in the incubator, the third temperature information of each temperature sensor is obtained and arranged in ascending or descending order to obtain a first temperature sequence. In one embodiment, the number of extracted temperature values ​​is determined based on the number of temperature sensors, and the temperature values ​​in the first sequence are extracted and the arithmetic mean is calculated to obtain the second temperature information. In another embodiment, the second temperature information is obtained according to the first temperature sequence using the median mean method.

[0106] Figure 3 A flow chart for adjusting heating parameters provided by an embodiment of the present invention is shown.

[0107] According to an embodiment of the present invention, Figure 3 As shown, the heating parameters and air volume parameters are adjusted according to the second temperature information and the door status information, specifically:

[0108] S302, determining target temperature information and an upper limit threshold of air volume according to the door status information;

[0109] S304: determining an air volume parameter according to the second temperature information and the air volume upper limit threshold;

[0110] S306, determining a first control quantity coefficient according to the air volume parameter;

[0111] S308, calculating the difference between the second temperature information and the target temperature information to obtain first temperature deviation information;

[0112] S310, obtaining at least a proportional control variable and an integral control variable according to the first temperature deviation information and the first control variable coefficient;

[0113] S312: Update the heating parameter according to the proportional control amount and the integral control amount.

[0114] It should be noted that, first, the target temperature and the upper limit threshold of the air volume are adjusted according to the state of the box door. When the box door is in the open state, in order to avoid the temperature being too high or the air volume being too large, which causes the heat to be continuously transferred to the operator, in this embodiment, the safety hazard is reduced by actively lowering the target temperature and setting the upper limit threshold of the air volume. Secondly, according to the temperature value of the incubator and the upper limit threshold of the air volume, the air volume parameters are adjusted to control the blast working state. Then, the difference between the incubator temperature and the target temperature is calculated, that is, the first temperature deviation information. According to the preset control quantity adjustment algorithm, the proportional control quantity is calculated according to the first temperature deviation information and the proportional coefficient in the first control quantity coefficient; the integral control quantity is calculated according to the integral value of the first temperature deviation information and the integral coefficient in the first control quantity coefficient. Finally, according to the proportional control quantity and the integral control quantity, the heating parameters are updated to adjust the heating control state of the heating control module.

[0115] Figure 4 A flow chart for adjusting air volume parameters provided by an embodiment of the present invention is shown.

[0116] According to an embodiment of the present invention, Figure 4 As shown, the air volume parameter is determined according to the second temperature information and the air volume upper limit threshold, specifically:

[0117] S402, obtaining fourth temperature information;

[0118] S404, obtaining second temperature deviation information according to the fourth temperature information and the second temperature information;

[0119] S406, determining first air volume information according to the second temperature deviation information;

[0120] S408, determining whether the first air volume information is lower than the air volume upper limit threshold;

[0121] S410: If yes, setting the air volume parameter according to the first air volume information;

[0122] S412: If not, setting the air volume parameter according to the air volume upper limit threshold.

[0123] It should be noted that in the embodiment, the air volume information is adjusted by analyzing the temperature difference between the sensors inside the temperature box, so as to improve the uniformity of the temperature inside the temperature box. According to the temperature value recorded by each sensor, that is, the fourth temperature information, and the temperature value of the temperature box, the second temperature deviation information is obtained according to the preset deviation value calculation algorithm, to represent the temperature deviation between each sensor inside the temperature box. Then, the second temperature deviation information is used to search the preset air volume corresponding table to obtain the first air volume information. Finally, it is judged whether the first air volume information is lower than the set air volume upper limit threshold value; if yes, it means that there is no safety risk in setting the air blowing state through the first air volume information, so the air volume parameter is set according to the first air volume information; if no, it means that there is a safety risk in setting the air blowing state through the first air volume information, so the air volume parameter is set according to the air volume upper limit threshold value.

[0124] According to the embodiment of the application, the box door control permission is set according to the second temperature information, specifically:

[0125] when the box door state is in a closed state;

[0126] whether the second temperature information is lower than a preset first temperature threshold value is judged;

[0127] if yes, the open door permission flag bit is set.

[0128] It should be noted that in the embodiment, the temperature inside the temperature box is analyzed to set whether the box door is allowed to be opened, so as to avoid opening the box door when the temperature inside the temperature box is high, affecting the use safety of the temperature box. When the temperature box temperature is lower than the preset first temperature threshold value, the open door permission flag bit is set to control the box door lock.

[0129] Figure 5 A management flowchart when the box door is opened is shown.

[0130] According to the embodiment of the application, as shown in Figure 5 the heating parameter information is adjusted or the first warning instruction is sent according to the first time information and the second temperature information, specifically:

[0131] S502, when the box door state is in an open state;

[0132] S504, a second control amount coefficient is obtained;

[0133] S506, the first temperature deviation information and the second control amount coefficient are used to update the heating parameter information according to a preset control amount strategy;

[0134] S508, whether the first time information exceeds a preset first time threshold value is judged;

[0135] S510: If yes, send a first abnormal instruction.

[0136] It should be noted that when the door is open, in order to compensate for the heat changes caused by the heat exchange between the interior of the incubator and the external environment and to increase the sensitivity of temperature changes, in this embodiment, the control quantity coefficient in the control quantity adjustment algorithm is adjusted to adjust the heating control quantity; wherein the control quantity coefficient includes at least a proportional coefficient and an integral coefficient. By adjusting the control quantity coefficient, the efficiency of temperature adjustment is improved. Then, when it is determined that the first time information exceeds the preset first time threshold, that is, when the duration of the door opening exceeds the set time, it indicates that there is a risk that the incubator will be difficult to maintain the temperature due to the long-term door opening, or that the operator has performed an erroneous operation of failing to close the door successfully. At this time, a first warning instruction is sent to provide a warning message to the incubator operator.

[0137] It is worth mentioning that it also includes:

[0138] Obtaining second temperature information according to the preset second quantity information;

[0139] Obtaining a fitting relationship according to the second temperature information and the second quantity information and a preset fitting strategy;

[0140] According to the fitting relationship and the derivation rule, the slope information is obtained.

[0141] It should be noted that in this embodiment, a predetermined number of incubator temperature values ​​are fitted to calculate a slope representing the rate of change of the incubator temperature. The most recently recorded incubator temperature information is obtained based on a predetermined second quantity, where the second quantity is at least 3. A linear fitting algorithm, such as the least squares method, is then used to obtain a fitting equation. The slope information is then obtained by applying a derivative rule to the fitting equation.

[0142] It is worth mentioning that it also includes:

[0143] When the door status is determined to be in the closed state;

[0144] Obtaining first slope information and second slope information;

[0145] Calculating a difference between the first slope information and the second slope information to obtain first slope difference information;

[0146] Determining whether the first slope difference information exceeds a preset slope threshold;

[0147] If so, the door status is set to the door open state.

[0148] It should be noted that, as an embodiment, the change in the slope of the incubator temperature is detected to determine whether the door is open. When the incubator temperature is higher than the ambient temperature, if the door is opened, due to the temperature difference between the inside of the incubator and the outside environment, heat exchange will occur, which will cause the incubator temperature to rapidly decrease. At this time, the slope of the temperature curve will decrease. The difference between the slope of the previous temperature curve and the slope of the current temperature curve is calculated to obtain first slope difference information. When the first slope difference information exceeds the preset slope threshold, it indicates that the slope of the temperature curve will decrease significantly, and it is determined that the door is open.

[0149] It is worth mentioning that it also includes:

[0150] When the door status is judged to be in the open state;

[0151] Calculating the difference between the target temperature information and the second temperature information to obtain first temperature difference information;

[0152] Determining whether the first temperature difference information is greater than a preset first temperature difference threshold;

[0153] If so, a second exception instruction is sent.

[0154] It should be noted that when the door is open, the difference between the target temperature and the incubator temperature is calculated to obtain first temperature difference information. If the first temperature difference information is greater than a preset first temperature difference threshold, it indicates that the incubator heat change caused by the door opening is too large, posing a risk of interfering with the incubator experiment. Therefore, a second abnormality instruction is issued to provide appropriate instructions to the operator.
