[0081] It should be noted that a thermostat device based on multi-sensor data fusion is provided with at least two independent temperature zones, each of which is provided with a number of temperature sensors to measure the temperature value of a set position in the temperature zone. Each independent temperature zone is provided with a fan to blow air into the temperature zone. The thermostat device is provided with a heater to heat all temperature zones at the same time.

[0082] Figure 2 A flow chart of a temperature box control method based on multi-sensor data fusion of the present invention is shown.

[0083] like Figure 2 As shown, the first aspect of the present invention discloses a temperature box control method based on multi-sensor data fusion, the method comprising:

[0084] S202, obtaining first temperature information;

[0085] S204, setting a corresponding temperature mode according to the first temperature information;

[0086] S206, obtaining second temperature information and third temperature information according to the first temperature information;

[0087] S208, determining heating information according to the second temperature information and the third temperature information;

[0088] S210, calculating the difference between the second temperature information and the third temperature information to obtain first temperature difference information;

[0089] S212, determining air volume information according to the first temperature difference information and the temperature mode;

[0090] S214: Control the temperature box according to the heating information and the air volume information.

[0091] It should be noted that the first temperature information is the temperature value of any temperature sensor in any temperature zone of the incubator; the second temperature information is the temperature arithmetic value of the first temperature zone; the third temperature information is the temperature arithmetic value of the second temperature zone; the heating information is the heating control parameter of the first heater; and the air volume information is the air volume control parameter of the first fan or the second fan.

[0092] In this embodiment, first, the temperature value of each position in each temperature zone is obtained through the temperature sensor in each temperature zone, and then the temperature value detected by the temperature sensor is determined to determine whether the temperature box is in the heating mode or the temperature control mode. Secondly, according to the temperature value detected by the temperature sensor in the same temperature zone, according to the preset mean value calculation method, including but not limited to the arithmetic mean algorithm, the weighted mean algorithm, etc., the temperature value of the first temperature zone and the temperature value of the second temperature zone, that is, the second temperature information and the third temperature information, are calculated. Then, in the corresponding working mode, according to the lower value of the second temperature information and the third temperature information, the adjustment amount of the heating parameter is calculated to update the heating parameter; and then the first heater is controlled to heat the first temperature zone and the second temperature zone according to the heating parameter. Finally, the difference between the second temperature information and the third temperature information is calculated to obtain the first temperature difference information, and the first air volume information of the first temperature zone and the second air volume information of the second temperature zone are respectively set in combination with the temperature mode in which the temperature box device is located, so as to control the blowing working state of the first fan and the second fan respectively. By real-time analysis of the temperature values ​​measured by multiple temperature sensors, the heating information and air volume information are adjusted to control the temperature box, thereby ensuring that the temperature control accuracy of each temperature zone meets the requirements, while ensuring that the temperature consistency between each temperature zone is within the set range.

[0093] Figure 3 A flow chart of confirming a temperature mode provided by an embodiment of the present invention is shown.

[0094] According to an embodiment of the present invention, Figure 3 As shown, the setting of the corresponding temperature mode according to the first temperature information is specifically:

[0095] S302, obtaining target temperature information;

[0096] S304, determining a first temperature threshold according to the target temperature information;

[0097] S306, determining whether the first temperature information is lower than the first temperature threshold;

[0098] S308, if yes, set the temperature mode to a heating mode;

[0099] S310, if not, setting the temperature mode to the temperature control mode.

[0100] It should be noted that, in this embodiment, the first temperature threshold is determined according to the target temperature value set in the incubator. Then, it is determined whether the first temperature information is lower than the first temperature threshold; if so, it means that the temperature value of the temperature zone in the incubator is low, and the temperature value of the temperature zone needs to be continuously heated by the heater to increase the temperature value, so it is determined to be in the heating mode at this time; if not, it means that the temperature value of the temperature zone in the incubator has reached the slow temperature control stage, which is used to ensure that the temperature value of the temperature zone can stably reach and maintain the set target temperature value, so it is determined to be in the temperature control mode at this time.

[0101] Figure 4 A flow chart of temperature box control in the heating mode provided by an embodiment of the present invention is shown.

[0102] According to an embodiment of the present invention, Figure 4 As shown, the heating information is determined according to the second temperature information or the third temperature information, specifically:

[0103] S402, when it is determined that the temperature mode is set to the heating mode;

[0104] S404, determining fourth temperature information according to the second temperature information and the third temperature information;

[0105] S406, calculating a difference between the fourth temperature information and the first temperature threshold to obtain first temperature deviation information;

[0106] S408, obtaining first heating control amount information according to the first temperature deviation information and the preset first control amount parameter and the preset control amount adjustment strategy;

[0107] S410: Adjust the heating information according to the first heating control amount information.

[0108] It should be noted that the fourth temperature information is the smaller value of the second temperature information and the third temperature information. In this embodiment, when the temperature box device is in the heating mode, first, the difference between the fourth temperature information and the first temperature threshold is calculated to obtain the first temperature deviation information. Then, according to the first temperature deviation information and the preset first control quantity parameter, the proportional control quantity, the integral control quantity and the differential control quantity are calculated; then the first heating control quantity information is obtained according to the proportional control quantity, the integral control quantity and the differential control quantity; wherein the first control quantity parameter includes at least the proportional weight, the integral weight and the differential weight. Finally, the heating information is updated according to the first heating control quantity information. Since heat transfer has a hysteresis, the heating quantity is adjusted according to the difference between the real-time temperature value and the first temperature threshold, so that the temperature value of the temperature zone can quickly reach the first temperature threshold and avoid the phenomenon of temperature overshoot.

[0109] According to an embodiment of the present invention, the air volume information is determined according to the first temperature difference information and the temperature mode, specifically:

[0110] When it is determined that the temperature mode is set to the heating mode;

[0111] Determining a first air volume adjustment value according to the first temperature deviation value information;

[0112] Determining whether the second temperature information is greater than the third temperature information;

[0113] If yes, setting the first air volume information according to the preset first air volume threshold and the first air volume adjustment value, and setting the second air volume information according to the preset first air volume threshold;

[0114] If not, the second air volume information is set according to the preset first air volume threshold and the first air volume adjustment value, and the first air volume information is set according to the preset first air volume threshold.

[0115] It should be noted that the use of a fan to blow air can help improve the temperature uniformity of the entire temperature zone, that is, reduce the temperature difference at different locations in the same temperature zone; high air volume will also cause heat loss in the temperature zone. In this embodiment, when the temperature box device is in the heating mode, the temperature deviation value of the sensor in each temperature zone is calculated respectively, recorded as the first temperature deviation value information, and used to look up the table to determine the first air volume adjustment value. Then, it is determined whether the second temperature information is greater than the third temperature information; if so, it means that the temperature value of the first temperature zone is higher than the temperature value of the second temperature zone. At this time, the first air volume information of the first temperature zone is set to the sum of the first air volume threshold and the first air volume adjustment value, and the second air volume information of the second temperature is set to the first air volume threshold; if not, it means that the temperature value of the first temperature zone is not higher than the temperature value of the second temperature zone. At this time, the first air volume information of the first temperature is set to the first air volume threshold; the second air volume information of the second temperature zone is set to the sum of the first air volume threshold and the first air volume adjustment value. In the heating mode, each temperature zone maintains a high air volume to improve the uniformity of the temperature value within the temperature zone; at the same time, for the temperature zone with higher temperature, a higher air volume is set to narrow the difference in temperature values ​​between the temperature zones.

[0116] Figure 5 A flow chart of temperature box control in temperature control mode provided by an embodiment of the present invention is shown.

[0117] According to an embodiment of the present invention, Figure 5 As shown, the heating information is determined according to the second temperature information or the third temperature information, specifically:

[0118] S502, when it is determined that the temperature mode is set to the temperature control mode;

[0119] S504, determining fourth temperature information according to the second temperature information and the third temperature information;

[0120] S506, calculating the difference between the fourth temperature information and the target temperature information to obtain second temperature deviation information;

[0121] S508, determining a second control amount parameter according to the fourth temperature information;

[0122] S510, obtaining second heating control amount information according to the second temperature deviation information and the preset second control amount parameter and the preset control amount adjustment strategy;

[0123] S512: Adjust the heating information according to the second heating control amount information.

[0124] It should be noted that the fourth temperature information is the smaller value of the second temperature information and the third temperature information. In this embodiment, when the temperature box device is in the temperature control mode, first, according to the difference between the fourth temperature information and the target temperature information, the second temperature deviation information is obtained to indicate the deviation between the temperature value of the temperature zone and the target temperature value, that is, the required temperature adjustment amount. Secondly, according to the fourth temperature information, the preset control quantity parameter corresponding table is searched to obtain the second control quantity parameter; wherein the second control quantity parameter includes at least a proportional weight, an integral weight and a differential weight; by setting different control quantity parameters at different temperatures, the oscillation amplitude of the temperature curve during the temperature adjustment process is reduced, and the stability of the temperature value of the temperature zone is improved. Then, according to the second temperature deviation information and the preset second control quantity parameter, the proportional control quantity, the integral control quantity and the differential control quantity are calculated; and then the second heating control quantity information is obtained according to the proportional control quantity, the integral control quantity and the differential control quantity. Finally, the heating information is updated according to the second heating control quantity information. By adjusting the second control quantity parameter in real time, it is ensured that the temperature value of the temperature zone can reach a steady state at the set target temperature value; in actual applications, the stable state of the temperature value used in medical and other fields is that the target temperature value does not exceed 0.5°C.

[0125] According to an embodiment of the present invention, the air volume information is determined according to the first temperature difference information and the temperature mode, specifically:

[0126] When it is determined that the temperature mode is set to the temperature control mode;

[0127] Determining a second air volume adjustment value according to the first temperature difference information;

[0128] determining fifth temperature information according to the second temperature information and the third temperature information;

[0129] determining a second air volume threshold according to the fifth temperature information and the target temperature information;

[0130] Determining whether the second temperature information is greater than the third temperature information;

[0131] If yes, setting the first air volume information according to the second air volume threshold and the second air volume adjustment value, and setting the second air volume information according to the second air volume threshold;

[0132] If not, the second air volume information is set according to the second air volume threshold and the second air volume adjustment value, and the first air volume information is set according to the second air volume threshold.

[0133] It should be noted that the fifth temperature information is the larger value of the second temperature information and the third temperature information. When in the temperature control mode, when the heater with fixed working parameters is heated, the heat loss of the temperature zone can be accelerated by high air volume to prevent the temperature value of the temperature zone from exceeding the steady-state range; the heat loss of the temperature zone can be reduced by low air volume to prevent the temperature value of the temperature zone from being lower than the steady-state range. In this embodiment, when the temperature box device is in the temperature control mode, first, according to the first temperature difference information, the second air volume adjustment value is determined by looking up the table. Secondly, according to the magnitude relationship between the fifth temperature information and the target temperature value, the second air volume threshold is obtained by looking up the table. Then, it is determined whether the second temperature information is greater than the third temperature information; if so, it means that the temperature value of the first temperature zone is higher than the temperature value of the second temperature zone. At this time, the first air volume information is set according to the sum of the second air volume threshold and the second air volume adjustment value, and the second air volume information is set according to the second air volume threshold; if not, it means that the temperature value of the first temperature zone is not higher than the temperature value of the second temperature zone. At this time, the second air volume information is set according to the sum of the second air volume threshold and the second air volume adjustment value, and the first air volume information is set according to the second air volume threshold. For temperature zones with higher temperatures, higher air volumes are used to reduce the temperature differences between the zones.

[0134] It is worth mentioning that it also includes:

[0135] Collect at least 2 pieces of first analog-to-digital information in sequence according to a preset time period;

[0136] According to the first analog information, second analog information is obtained according to a preset filtering processing strategy;

[0137] According to the second module information, first temperature information is obtained according to a preset temperature value correspondence table;

[0138] According to all the first temperature information in the same temperature zone, the second temperature information or the third temperature information is obtained according to a preset mean value calculation strategy.

[0139] It should be noted that, as an implementation, a temperature sensor signal is received by an analog-to-digital converter to obtain temperature information. For any temperature sensor in the temperature zone, first, according to a preset time period, the first analog-to-digital information is collected and converted in sequence. Secondly, according to a preset filtering processing algorithm, including but not limited to a low-pass filter, a weighted mean filter, a Huffman filter, etc., the second analog-to-digital information is obtained, which is used to look up the table and convert to obtain the first temperature information. Then, according to the temperature value detected by the temperature sensor in the same temperature zone, according to the preset mean calculation method, including but not limited to the arithmetic mean algorithm, the weighted mean algorithm, etc., the temperature value of the first temperature zone and the temperature value of the second temperature zone, that is, the second temperature information and the third temperature information are calculated.

[0140] It is worth mentioning that it also includes:

[0141] When it is determined that the temperature mode is set to the heating mode;

[0142] Obtaining second temperature difference information according to all first temperature information in the same temperature zone;

[0143] Determine whether the second temperature difference information exceeds a preset first temperature difference threshold;

[0144] If so, adjust the heating information downward.

[0145] It should be noted that in this embodiment, when the temperature box device is in the heating mode, first, the second temperature difference information is calculated based on the first temperature information of the same temperature zone; wherein the second temperature difference information is the difference between the maximum value and the minimum value in the first temperature information. Then, when it is judged that the second temperature difference information exceeds the preset first temperature difference threshold, it means that the temperature difference between different areas in the temperature zone is large; because when in the heating mode, the set air volume is in a large situation, the air volume is limited to increase the space, therefore, it is necessary to reduce the temperature rise of the local area in the temperature zone by adjusting the heating information downward, so as to improve the uniformity of the temperature value in the temperature zone.

[0146] It is worth mentioning that it also includes:

[0147] When it is determined that the temperature mode is set to the heating mode;

[0148] Obtaining second temperature difference information according to all first temperature information in the same temperature zone;

[0149] Determine whether the second temperature difference information exceeds a preset second temperature difference threshold;

[0150] If so, the first air volume information or the second air volume information is adjusted upward, and the heating information is adjusted upward according to the air volume information.

[0151] It should be noted that, in this embodiment, when the temperature box device is in the temperature control mode, first, the second temperature difference information is calculated based on the first temperature information of the same temperature zone; wherein the second temperature difference information is the difference between the maximum value and the minimum value in the first temperature information. Then, when it is determined that the second temperature difference information exceeds the preset second temperature difference threshold, it means that the temperature difference between different areas in the temperature zone is large. At this time, the uniformity of the temperature value in the temperature zone is improved by increasing the first air volume information or the second air volume information. In addition, in order to ensure that the temperature value of the temperature zone can maintain a steady state, while increasing the air volume of the temperature zone, the heating information needs to be increased according to the set adjustment relationship.

[0161] According to an embodiment of the present invention, Figure 7 As shown, the temperature acquisition module includes:

[0162] The first temperature zone sensor 6021 includes at least four temperature sensors disposed at set positions in the first temperature zone, and is used to measure the temperature values ​​at corresponding positions in the first temperature zone;

[0165] It should be noted that the temperature box device is provided with a first temperature zone and a second temperature zone, and at least four temperature sensors are provided in each temperature zone to detect the temperature conditions at four different positions in the temperature zone.

[0170] It should be noted that the temperature box device is provided with a first temperature zone and a second temperature zone, and each temperature zone is provided with a fan to perform air blowing operation.

[0176] It should be noted that the fourth temperature information is the lower temperature value in the first temperature zone and the second temperature zone. The control quantity weight module obtains the control quantity parameter according to the fourth temperature information in accordance with the corresponding temperature mode, which is used for weighted calculation of the heating control quantity module. The heating control quantity module calculates the proportional control quantity, the integral control quantity and the differential control quantity according to the temperature deviation value and the control quantity parameter, respectively, and calculates the heating control quantity; and then uses the heating control quantity to update the heating information. Finally, the heater adjusts the heating working state according to the heating information.
