[0078] 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.

[0079] Figure 1 A flow chart of a method for controlling temperature intervals and intelligent door opening of a thermostat according to the present invention is shown.

[0080] like Figure 1 As shown, the first aspect of the present invention discloses a method for controlling temperature intervals of an incubator and intelligent door opening management, the method comprising:

[0081] S102, obtaining first temperature information;

[0082] S104, obtaining second temperature information according to the first temperature information;

[0083] S106, obtaining door status information;

[0084] S108, adjusting heating parameters and air volume parameters according to the second temperature information and the door state information;

[0085] S110, determining whether the door is in a closed state;

[0086] S112: If yes, set the door control authority according to the second temperature information;

[0087] S114, if not, obtaining first time information;

[0088] S116: Adjust heating parameter information or send a first warning instruction according to the first time information and the second temperature information.

[0089] It should be noted that the first temperature information is the temperature value measured by each temperature sensor in the incubator; the second temperature information is the temperature value of the incubator; the door status information is the opening and closing status of the incubator door, including the door closed state and the door open state; the heating parameter is the parameter for controlling the heating power of the heater of the incubator; the air volume parameter is the parameter for controlling the blowing air volume of the fan of the incubator; the first time information is the duration that the incubator door is in the open state.

[0090] In this embodiment, first, the temperature measurement values ​​of each temperature sensor in the incubator are verified, including but not limited to limit verification and change rate verification, to verify whether the temperature measurement value is an abnormal value. According to the temperature measurement values ​​of several temperature sensors belonging to normal values, the temperature value of the incubator is calculated according to the set filtering processing algorithm and mean algorithm. Then, according to the state of the door, the upper limit threshold of the air volume is set to avoid too high air volume when the door is open, thereby reducing the potential safety hazards in use. According to the temperature value of the incubator and the recorded values ​​of each temperature sensor, the uniformity of the temperature in the incubator is analyzed. When the temperature difference of each position inside the incubator is large, the temperature distribution is uniformly promoted by high air volume; when the temperature difference of each position inside the incubator is small, the air volume can be reduced to reduce the heat loss inside the incubator. By calculating the difference between the incubator temperature value and the target temperature value, the heating output setting of the heating unit is adjusted according to the temperature difference according to the set control quantity calculation strategy; through real-time feedback adjustment, the efficiency and stability of temperature control are improved, and the fluctuation amplitude of the incubator temperature is limited. Finally, when it is determined that the thermostat is in the state of door closing, the door opening permission flag is set according to the thermostat temperature value 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 state of door opening, there is heat exchange between the inside of the thermostat and the external environment, which is easy to affect the temperature value of the thermostat. By adjusting the control quantity coefficient of the control quantity calculation strategy, the sensitivity of temperature change is improved, so that when the temperature of the thermostat changes, the heating parameters can be adjusted more quickly, thereby reducing the fluctuation range of the thermostat temperature. In addition, by recording the length of time that the thermostat is in the door opening state, if the length of time is too long, it means that the thermostat is at risk of being difficult to maintain the temperature due to the long-term door opening, or the operator has performed an erroneous operation of failing to close the door successfully. At this time, by sending the first warning instruction, a warning message is provided to the thermostat operator.

[0091] Figure 2 A verification flow chart of the first temperature information provided by an embodiment of the present invention is shown.

[0092] 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:

[0093] S202, obtaining first temperature information according to a preset first time period;

[0094] S204, determining whether the first temperature information is within a preset first temperature range;

[0095] S206, if yes, obtaining change rate information according to the first temperature information;

[0096] S208, determining whether the change rate information is less than a preset change rate threshold;

[0097] S210: If yes, obtain third temperature information according to the first temperature information;

[0098] S212: Obtain the second temperature information according to the three temperature information and a preset filtering and averaging strategy.

[0099] It should be noted that the third temperature information is the data processing value of the first temperature information, that is, the arithmetic process value of the measurement value of each temperature sensor. In this embodiment, the temperature measurement value output by the temperature sensor is analyzed for amplitude and change rate to determine whether the first temperature information is an abnormal interference value. First, for each temperature sensor, at least two first temperature information are collected according to a set time period. Secondly, it is determined whether the first temperature information is within the set temperature range. If so, it means that the first temperature information belongs to a normal value; wherein the above temperature range is determined by the target temperature and the room temperature. In practical applications, if the set target temperature value is 37°C and the room temperature is 25°C, the above set range is set to 15°C to 47°C. Then, according to the several first temperature information measured by each temperature sensor, the change amplitude of the temperature value measured each time is calculated, and then converted into a change rate. When the change rate is less than the preset change rate threshold, it means that the first temperature information belongs to a normal value. Finally, according to the several first temperature information collected, the arithmetic mean is calculated to obtain the third temperature information as the arithmetic process value for calculating the second temperature information.

[0100] According to an embodiment of the present invention, the second temperature information is obtained according to the three temperature information and a preset filtering and averaging strategy, specifically:

[0101] According to the preset quantity, searching and obtaining fourth temperature information;

[0102] According to the third temperature information and the fourth temperature information, and in accordance with a preset filtering strategy, updating and recording the third temperature information;

[0103] obtaining first quantity information;

[0104] Obtaining a first temperature sequence according to the first quantity information and the third temperature information in a preset arrangement order;

[0105] According to the first quantity information, the temperature values ​​in the first temperature sequence are extracted, and the second temperature information is obtained according to a preset mean algorithm.

[0106] It should be noted that the fourth temperature information is the storage value of the third temperature information after data processing, that is, the temperature detection record value of each temperature sensor in the memory; the first quantity information is the number of temperature sensors set in the incubator to measure the internal temperature of the incubator. In this embodiment, the temperature record values ​​of at least two temperature sensors, that is, the fourth temperature information, are obtained, combined with the third temperature information, and the third temperature information is updated according to a preset filtering algorithm; wherein the filtering algorithm includes but is not limited to a Butterworth low-pass filtering algorithm, a Chebyshev low-pass filtering algorithm, a Kalman filtering algorithm, etc., to further reduce the interference of detection noise and improve the accuracy of temperature. Then, according to the number of temperature sensors in the incubator, the third temperature information of each temperature sensor is obtained, and the third temperature information is arranged in ascending or descending order to obtain a first temperature sequence. As an implementation method, the number of extractions is determined according to the number of temperature sensors, which is used to extract the temperature values ​​in the first sequence, calculate the arithmetic mean, and obtain the second temperature information. As another implementation method, according to the first temperature sequence, the second temperature information is obtained according to the median mean method.

[0107] Figure 3 A flow chart for adjusting heating parameters provided by an embodiment of the present invention is shown.

[0108] 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:

[0109] S302, determining target temperature information and an upper limit threshold of air volume according to the door status information;

[0110] S304, determining an air volume parameter according to the second temperature information and the air volume upper limit threshold;

[0111] S306, determining a first control amount coefficient according to the air volume parameter;

[0112] S308, calculating the difference between the second temperature information and the target temperature information to obtain first temperature deviation information;

[0113] S310, obtaining at least a proportional control amount and an integral control amount according to the first temperature deviation information and the first control amount coefficient;

[0114] S312: Update the heating parameter according to the proportional control amount and the integral control amount.

[0115] It should be noted that, first, according to the state of the box door, the target temperature and the upper limit threshold of the air volume are adjusted. 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 transmitted 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.

[0116] Figure 4 A flow chart for adjusting air volume parameters provided by an embodiment of the present invention is shown.

[0117] 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:

[0118] S402, obtaining fourth temperature information;

[0119] S404, obtaining second temperature deviation information according to the fourth temperature information and the second temperature information;

[0120] S406, determining first air volume information according to the second temperature deviation information;

[0121] S408, determining whether the first air volume information is lower than the air volume upper limit threshold;

[0122] S410: If yes, setting the air volume parameter according to the first air volume information;

[0123] S412: If not, setting the air volume parameter according to the air volume upper limit threshold.

[0124] It should be noted that in this embodiment, the air volume information is adjusted by analyzing the temperature difference between the various sensors inside the incubator, thereby improving the uniformity of the temperature inside the incubator. According to the temperature values ​​recorded by each sensor, that is, the fourth temperature information, and the incubator temperature value, the second temperature deviation information is obtained according to the preset deviation value calculation algorithm to indicate the temperature deviation between the various sensors inside the incubator. Then, the preset air volume correspondence table is searched according to the second temperature deviation information to obtain the first air volume information. Finally, it is determined whether the first air volume information is lower than the set air volume upper limit threshold; if so, it means that there is no safety risk in setting the blowing state through the first air volume information, so the air volume parameters are set according to the first air volume information; if not, it means that there is a safety risk in setting the blowing state through the first air volume information, so the air volume parameters are set according to the air volume upper limit threshold.

[0125] According to an embodiment of the present invention, the door control authority is set according to the second temperature information, specifically:

[0126] When the door state is judged to be in the door closed state;

[0127] Determining whether the second temperature information is lower than a preset first temperature threshold;

[0128] If so, the door opening permission flag will be set.

[0129] It should be noted that in this embodiment, the temperature inside the incubator is analyzed to set whether to allow the door to be opened, so as to avoid opening the door when the temperature inside the incubator is high, which affects the safety of the incubator. When the door is closed, the door opening flag is set when the temperature of the incubator is lower than the preset first temperature threshold to control the door lock.

[0130] Figure 5 A management flow chart when the cabinet door is opened provided by an embodiment of the present invention is shown.

[0131] According to an embodiment of the present invention, Figure 5 As shown, adjusting the heating parameter information or sending the first warning instruction according to the first time information and the second temperature information is specifically:

[0132] S502, when it is determined that the door state is in the door open state;

[0133] S504, obtaining a second control variable coefficient;

[0134] S506, updating the heating parameter information according to the second control amount coefficient and the second control amount coefficient and a preset control amount strategy;

[0135] S508, determining whether the first time information exceeds a preset first time threshold;

[0136] S510: If yes, send a first abnormal instruction.

[0137] It should be noted that when the door is in the open state, in order to compensate for the heat changes caused by the heat exchange between the inside of the thermostat and the external environment, and to improve 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 means that there is a risk that the thermostat is difficult to maintain the temperature due to the long-term opening of the door, or the operator has performed an erroneous operation of failing to close the door successfully. At this time, a warning message is provided to the operator of the thermostat by sending a first warning instruction.

[0138] It is worth mentioning that it also includes:

[0139] Obtaining second temperature information according to preset second quantity information;

[0140] According to the second temperature information and the second quantity information, a fitting relationship is obtained according to a preset fitting strategy;

[0141] According to the fitting relationship, the slope information is obtained according to the derivation rule.

[0142] It should be noted that, in this embodiment, a preset number of incubator temperature values ​​are fitted to calculate a slope to represent the incubator temperature change rate. According to the preset second quantity information, the latest recorded incubator temperature information is obtained; wherein the second quantity information is at least 3. Then, according to a linear fitting algorithm such as the least squares method, a fitting relationship is obtained. According to the derivation rule of the fitting relationship, the slope information can be obtained.

[0143] It is worth mentioning that it also includes:

[0144] When it is judged that the door state is in the door closed state;

[0145] Acquire first slope information and second slope information;

[0146] Calculating a difference between the first slope information and the second slope information to obtain first slope difference information;

[0147] Determining whether the first slope difference information exceeds a preset slope threshold;

[0148] If yes, the door status is set to the door open status.

[0149] It should be noted that, as an implementation method, 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 of the 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 the first slope difference information; when the first slope difference information exceeds the preset slope threshold, it means that the slope of the temperature curve will decrease significantly, and it is determined that the door is open.

[0150] It is worth mentioning that it also includes:

[0151] When it is determined that the door state is in the door open state;

[0152] Calculating the difference between the target temperature information and the second temperature information to obtain first temperature difference information;

[0153] Determine whether the first temperature difference information is greater than a preset first temperature difference threshold;

[0154] If yes, a second exception instruction is sent.

[0155] It should be noted that when the door is open, the difference between the target temperature and the temperature of the incubator is calculated to obtain the first temperature difference information. If the first temperature difference information is greater than the preset first temperature difference threshold, it means that the heat change of the incubator caused by the door opening is too large, and there is a risk of interfering with the incubator experiment. Therefore, the second abnormal instruction is sent to provide corresponding instructions to the operator.
