[0078] Figure 1 A flow chart of a method for separating and controlling a thermostat fan and a heating system according to the present invention is shown.

[0079] like Figure 1 As shown, the first aspect of the present invention discloses a method for separating a thermostat fan from a heating system, the method comprising:

[0080] S102, determining whether the first switching instruction information is accepted;

[0081] S104, if yes, setting the temperature mode to a rapid drop mode;

[0082] S106, if not, obtaining the first temperature information and the target temperature information;

[0083] S108, determining first temperature lower limit information and first temperature upper limit information according to the target temperature information;

[0084] S110, when it is determined that the first temperature information is lower than the first temperature lower limit information, setting the temperature mode to a heating mode;

[0085] S112, when it is determined that the first temperature information exceeds the first temperature upper limit information, setting the temperature mode to a cooling mode;

[0086] S114, obtaining first temperature deviation information;

[0087] S116: Adjust fan parameters and heating parameters according to the first temperature deviation information and the first temperature information and the corresponding temperature mode.

[0088] It should be noted that the first switching instruction information is an instruction to switch the incubator to the rapid drop mode; the first temperature information is the temperature value of the incubator; the target temperature information is the temperature value that the set incubator needs to reach; and the first temperature deviation information is the maximum value of the temperature deviation of each area in the incubator.

[0089] In this embodiment, first, it is determined whether the first switching instruction information is received; if so, it indicates that the control instruction is obtained for executing the rapid cooling operation; if not, the temperature value of the incubator is detected in real time to determine the temperature mode of the incubator. Secondly, according to the set incubator target temperature value, the first temperature lower limit information and the first temperature upper limit information are determined; wherein, the setting information of the upper and lower limits of the temperature is usually set by the field in which the incubator is applied. For example, in the medical field, it is usually set to ±3°C of the target temperature value. Assuming that the target temperature is 37.5°C, the first temperature lower limit information is 34.5°C and the first temperature upper limit information is 40.5°C. Then, according to the comparison of the size relationship between the first temperature information and the first temperature lower limit information and the first temperature upper limit information, the temperature mode is determined; when the first temperature information is lower than the first temperature lower limit information, it indicates that the incubator temperature value is too low at this time, so the temperature mode of the incubator is set to the heating mode; when the first temperature information exceeds the first temperature upper limit information, it indicates that the incubator temperature value is too high at this time, so the temperature mode of the incubator is set to the cooling mode. Finally, according to the first temperature deviation information and the first temperature information, the fan parameters of the fan and the heating parameters of the heater are adjusted according to the corresponding temperature mode; by adjusting the fan parameters, the speed of heat loss in the temperature box can be changed; by adjusting the heating parameters, the speed of heat replenishment in the temperature box can be changed. By independently controlling the fan and the heater, the flexibility of temperature control and the efficiency of temperature regulation of the temperature box are improved.

[0090] Figure 2 A flow chart of detecting 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, it also includes:

[0092] S202, obtaining first quantity information;

[0093] S204, obtaining collected temperature information according to the first quantity information;

[0094] S206, obtaining first temperature information according to the collected temperature information and a preset mean value calculation strategy;

[0095] S208: Determine first temperature deviation information according to the collected temperature information.

[0096] It should be noted that the first quantity information is the number of temperature sensors set in the incubator. Multiple temperature sensors are set in the incubator to measure the temperature value of the set position in the incubator in real time, that is, to collect temperature information. Then, according to the preset mean calculation strategy, including but not limited to the arithmetic mean algorithm, the weighted mean algorithm, the filtered mean algorithm, etc., the mean of the collected temperature is calculated as the temperature value of the incubator. Finally, the difference between the maximum and minimum values ​​of the collected temperature information is calculated as the first temperature deviation information, which is used to indicate the uniformity of the temperature in the incubator; the larger the deviation value, the lower the temperature uniformity; the smaller the deviation value, the higher the temperature uniformity.

[0097] According to an embodiment of the present invention, it also includes:

[0098] According to the preset first time information, collect and record the first temperature information;

[0099] Generate a temperature coordinate point according to the first time information and the first temperature information;

[0100] Based on the temperature coordinate points, a temperature curve is drawn and displayed.

[0101] It should be noted that the first temperature information of the thermostat is continuously collected at intervals according to the set first time information. Then, the temperature coordinate point is obtained each time the temperature is collected, with time as the horizontal coordinate and the temperature value as the vertical coordinate. Finally, a temperature curve is drawn according to the temperature coordinate points, and then the temperature curve is displayed through the display unit of the thermostat, so that the thermostat operator can clearly and intuitively observe the temperature changes inside the thermostat, thereby improving the operator's experience.

[0102] Figure 3 A control flow chart of a fan when a speed reduction mode is provided according to an embodiment of the present invention is shown.

[0103] According to an embodiment of the present invention, Figure 3 As shown, adjust the fan parameters and heating parameters according to the corresponding temperature mode, specifically:

[0104] S302, when it is determined that the temperature mode is a rapid drop mode;

[0105] S304, the fan parameter is set to a preset first fan parameter;

[0106] S306, the heating parameter is set to 0;

[0107] S308, judging whether the first temperature information is in a stable state according to the temperature curve;

[0108] S310: If yes, set the fan parameter to 0.

[0109] It should be noted that when the temperature mode is judged to be the rapid drop mode, it is necessary to stop the heating work of the heater and set a high air volume to achieve the purpose of rapid cooling. First, the fan parameter is set to the preset first fan parameter, where the first fan parameter is usually the fan in the maximum air volume state. Then, the heating parameter is set to 0 to stop the heater from heating. Finally, based on information such as the slope of the temperature curve, it is determined whether the first temperature information of the temperature box is in a stable state; if so, it means that the rapid cooling is over, and the fan parameter is set to 0 to stop the blowing state.

[0110] According to an embodiment of the present invention, judging whether the first temperature information is in a stable state according to the temperature curve is specifically:

[0111] Determining whether the first temperature information is lower than a preset first temperature threshold;

[0112] If yes, whether the first temperature information is in a stable state;

[0113] If not, then obtaining the first slope information of the latest temperature coordinate point position according to the temperature curve;

[0114] Determining whether the first slope information is within a preset first slope range;

[0115] If yes, whether the first temperature information is in a stable state;

[0116] If not, whether the first temperature information is in an unstable state.

[0117] It should be noted that when judging that the temperature mode is the rapid drop mode, first, judge whether the first temperature information of the incubator is lower than the preset first temperature threshold, wherein the first temperature threshold is a set safety temperature value, which is usually set between 25°C and 30°C in practical applications; if so, it means that the temperature value of the incubator has reached the set safety temperature range, and it can be considered to be in a stable state; if not, calculate the first slope information of the latest temperature coordinate point in the temperature curve. Judge whether the first slope information is within the preset first slope range; if so, it means that the temperature value of the incubator changes little, and it is considered to be in a stable state; if not, it means that the temperature value of the incubator changes greatly and is in an unstable state. As an implementation method, a linear fitting expression is obtained by linearly fitting a number of temperature coordinate points, and the first slope information is obtained from the expression.

[0118] Figure 4 The control flow chart of the fan and the heater when the temperature rise mode is provided in an embodiment of the present invention is shown.

[0119] According to an embodiment of the present invention, Figure 4 As shown, according to the first temperature deviation information and the first temperature information, the fan parameters and the heating parameters are adjusted according to the corresponding temperature mode, specifically:

[0120] S402, when it is determined that the temperature mode is a heating mode;

[0121] S404, determining first weighted information and the fan parameter according to the first temperature deviation information;

[0122] S406, calculating a difference between the first temperature information and the target temperature information to obtain first temperature difference information;

[0123] S408, obtaining a heating adjustment amount according to the first temperature difference information and the first weighted information and a preset heating control amount adjustment strategy;

[0124] S410, obtaining a heating parameter according to the heating adjustment amount.

[0125] It should be noted that when judging that the temperature mode is the heating mode, first, according to the first temperature deviation information, according to the set calculation rules, the first weighted information and the fan parameters are obtained, and the blowing state of the fan is controlled by setting the fan parameters; wherein the first weighted information at least includes a proportional weight parameter and an integral weight parameter. Then, the difference between the first temperature information and the target temperature information is calculated to obtain the first temperature difference information to represent the temperature value to be adjusted; according to the first temperature difference information, the proportional control amount and the integral control amount are calculated, and then the proportional control amount and the integral control amount are weighted according to the first weighted information to obtain the heating adjustment amount. Finally, the heating parameters are updated through the heating control amount to adjust the heating state of the heater. Since heat conduction has a hysteresis, the temperature value is measured in real time to feedback and adjust the heating state, thereby improving the speed and stability of temperature changes during the heating process.

[0126] According to an embodiment of the present invention, determining the first weighted information and the fan parameter according to the first temperature deviation information further includes:

[0127] Determining whether the first temperature information is lower than the second temperature lower limit information;

[0128] If yes, the fan parameter is set to a preset second fan parameter;

[0129] If not, determining the fan parameters according to the first temperature deviation information;

[0130] According to the wind turbine parameters, first weighted information is determined.

[0131] It should be noted that when judging that the temperature mode is the heating mode, the first weighted information and the fan parameters are determined according to the first temperature deviation information. First, determine whether the first temperature information is lower than the second temperature lower limit information; if so, it means that the temperature value is too low, and it is necessary to reduce the heat loss of the incubator by a lower blowing volume, so the fan parameters are set to the preset second fan parameters; if not, it means that the slow heating state is entered at this time, and it is necessary to ensure the uniformity of the incubator temperature, and the fan parameters are determined by looking up the table according to the first temperature deviation information; the larger the temperature deviation, the larger the blowing volume is used to make the temperature values ​​of various positions in the incubator tend to be the same. Then, according to the fan parameters, the first weighted information is determined by looking up the table, which is used to adjust the heating adjustment amount to offset the heat loss caused by blowing.

[0132] Figure 5 A control flow chart of a fan and a heater when a cooling mode is provided according to an embodiment of the present invention is shown.

[0133] According to an embodiment of the present invention, Figure 5 As shown, according to the first temperature deviation information and the first temperature information, the fan parameters and the heating parameters are adjusted according to the corresponding temperature mode, specifically:

[0134] S502, when it is determined that the temperature mode is a cooling mode;

[0135] S504, determining a heating parameter according to the first temperature information;

[0136] S506, calculating a difference between the first temperature information and the target temperature information to obtain first temperature difference information;

[0137] S508, obtaining an air volume adjustment amount according to the first temperature difference information and a preset air volume control amount adjustment strategy;

[0138] S510: Obtain an air volume parameter according to the air volume adjustment amount.

[0139] It should be noted that when the temperature mode is determined to be the cooling mode, first, the heating parameters are determined based on the magnitude relationship between the first temperature information and the second temperature upper limit information to control the heating state of the heater. Then, the difference between the first temperature information and the target temperature information is calculated to obtain the first temperature difference information, which is used to calculate the proportional control amount and the integral control amount of the air volume control amount, and is used to update the air volume parameters and adjust the blowing state of the fan. Since the blowing can quickly realize the heat exchange between the internal temperature of the incubator and the ambient temperature, the temperature value is measured in real time to feedback and adjust the blowing state, thereby improving the stability of the temperature change during the blowing cooling process.

[0140] According to an embodiment of the present invention, determining the heating parameter according to the first temperature information is specifically:

[0141] Determining whether the first temperature information exceeds the second temperature upper limit information;

[0142] If yes, the heating parameter is set to 0;

[0143] If not, the heating parameter is set to a preset first heating parameter.

[0144] It should be noted that when the temperature mode is judged to be the cooling mode, the heating parameters are determined according to the size relationship between the first temperature information and the second temperature upper limit information. Determine whether the first temperature information exceeds the second temperature upper limit information; if so, it means that the temperature of the incubator is too high and heating needs to be stopped to achieve the purpose of cooling; if not, it means that the temperature of the incubator has entered the slow cooling cutoff, and fixed heating parameters need to be set so that the heater is in a heat radiation state to improve the control efficiency of the heater. In actual applications, since it takes a long time for the heater to go from the cooling state to the heating state, it is necessary to wake up the heater in advance to reduce the waiting time for heating.

[0145] According to an embodiment of the present invention, it also includes:

[0146] According to the target temperature information, first temperature upper limit information, second temperature upper limit information, first temperature lower limit information and second temperature lower limit information are determined,

[0147] The temperature values ​​are arranged in order from small to large: the second temperature lower limit information, the first temperature lower limit information, the target temperature information, the first temperature upper limit information, and the second temperature upper limit information.

[0148] It should be noted that, in this embodiment, the first temperature upper limit information, the second temperature upper limit information, the first temperature lower limit information, and the second temperature lower limit information are determined by the target temperature information. Moreover, the second temperature lower limit information, the first temperature lower limit information, the target temperature information, the first temperature upper limit information, and the second temperature upper limit information. Taking the medical field as an example, if the target temperature value is 37.5°C, the second temperature lower limit information is 43.5°C, the first temperature lower limit information is 40.5°C, the first temperature upper limit information is 34.5°C, and the second temperature upper limit information is 31.5°C.

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

[0150] Determining whether the first temperature information is higher than a preset third temperature upper limit information;

[0151] If so, the temperature mode is set to rapid drop mode and an over-temperature warning sign is displayed.

[0152] It should be noted that when the first temperature information is higher than the preset third temperature upper limit information, the incubator is deemed to be in an over-temperature state and there is an operational risk. At this time, the temperature mode is set to the rapid drop mode to achieve automatic rapid cooling. In addition, an over-temperature warning is displayed on the display unit of the incubator to provide the operator with an intuitive abnormal state of the incubator.

[0153] It is worth mentioning that it also includes:

[0154] Obtaining a preset number of temperature coordinate points;

[0155] According to the temperature coordinate point, and in accordance with a preset linear fitting strategy, second slope information and first variance information are obtained;

[0156] Determining whether the second slope information is within a preset first slope range;

[0157] If yes, determining whether the first variance information is lower than a preset variance threshold;

[0158] If so, the first time information is adjusted upward.

[0159] It should be noted that a preset number of temperature coordinate points are selected, and a fitted linear relationship is obtained according to a preset linear fitting strategy, such as the least squares method, to determine the second slope information and the first variance information; wherein the second slope information is the slope value of the above linear relationship, and the first variance information is the degree of deviation of the fitting. When the second slope information is within the preset first slope range, it indicates that the temperature change value of the incubator is low. At this time, if the first variance information is lower than the preset variance threshold, it indicates that the curve fits the actual state. Therefore, it is determined that the incubator temperature is in a stable state, and the frequency of temperature collection can be reduced by increasing the first time information, thereby reducing the computing power requirements and power consumption.
