Description

Technical Field

[0001] The present application relates to the field of medical technology, and in particular to a method and system for controlling power consumption of a physical cooling device for children. Background Art

[0002] Fever is a common symptom in infants and young children. Because young infants lack a robust body temperature regulation system, persistent high fever can hinder the functioning of their central nervous system and, in severe cases, threaten their lives. Therefore, physical cooling of patients with moderate to high fevers can effectively reduce localized high fever through heat exchange, providing effective protection.

[0003] Currently, semiconductor cooling or heating is primarily controlled by relays, which control the polarity of the semiconductor to achieve cooling or heating. Specifically, power is shut off when the sheath temperature approaches the set temperature, heating is activated when the sheath temperature is below the set temperature, and cooling is activated when the sheath temperature is above the set temperature.

[0004] However, the coolant is the water in the entire water tank. When the water volume increases, it will affect the heating and cooling rate, increase power consumption, and easily start and stop the semiconductor frequently when the temperature is close to the target value. Since semiconductors are power devices, frequent start and stop consumes more power, and the battery life of battery-powered systems will be greatly reduced. Summary of the Invention

[0042] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0043] Fever is a common symptom in infants and young children. Because young infants lack a robust body temperature regulation system, persistent high fever can hinder the functioning of their central nervous system and, in severe cases, threaten their lives. Therefore, physical cooling of patients with moderate to high fevers can effectively reduce localized high fever through heat exchange, providing effective protection.

[0044] Currently, semiconductor cooling or heating is primarily controlled by relays, which control the polarity of the semiconductor to achieve cooling or heating. Specifically, power is shut off when the sheath temperature approaches the set temperature, heating is activated when the sheath temperature is below the set temperature, and cooling is activated when the sheath temperature is above the set temperature.

[0045] However, the coolant is the water in the entire water tank. When the water volume increases, it will affect the heating and cooling rate, increase power consumption, and easily start and stop the semiconductor frequently when the temperature is close to the target value. Since semiconductors are power devices, frequent start and stop consumes more power, and the battery life of battery-powered systems will be greatly reduced.

[0046] To address this issue, the present application provides a method and system for controlling the power consumption of a children's physical cooling device, which is applied to the power consumption control system of the children's physical cooling device; the power consumption control system of the children's physical cooling device includes a central processing unit, a temperature sensor, a first evaporative condenser, a water tank, and a sheath; the temperature sensor is located between the first evaporative condenser and the water tank; the temperature sensor is connected to the central processing unit; and the water tank is connected to the sheath. Power consumption control of a children's physical cooling device. In the present application, the current water temperature of the first evaporative condenser is collected by a temperature sensor, and the frequency and duty cycle of the PWM signal are adjusted in real time according to the temperature difference between the current water temperature and the set temperature, so as to adjust the output power of the semiconductor to increase or decrease the temperature of the water in the sheath, thereby achieving real-time control of the control frequency and duty cycle of the semiconductor by the temperature difference between the current water temperature and the set temperature. At the same time, by improving the water path, the cooling and heating efficiency and the heat dissipation efficiency are greatly improved, which can significantly reduce the power consumption of the semiconductor, thereby improving the endurance of the system.

[0047] Figure 1 This is a flow chart of the power consumption control method of the children's physical cooling device provided in the embodiment of the present application. It should be noted that the power consumption control system of the children's physical cooling device is applied; the power consumption control system of the children's physical cooling device includes a central processing unit, a temperature sensor, a first evaporative condenser, a water tank and a sheath; the temperature sensor is located between the first evaporative condenser and the water tank; the temperature sensor is connected to the central processing unit; the water tank is connected to the sheath. For example, Figure 2 As shown (some devices are not shown).

[0048] like Figure 1 As shown, the power consumption control method of the children's physical cooling device in the embodiment of the present application may specifically include:

[0049] S101. The current water temperature of the first evaporative condenser is collected by a temperature sensor, and the temperature difference between the current water temperature and the set temperature is calculated by a central processing unit.

[0050] S102. The central processing unit (CPU) controls the frequency and duty cycle of the PWM signal in real time based on the temperature difference between the current water temperature and the set temperature.

[0051] S103 , adjusting the output power of the semiconductor based on the frequency and duty cycle of the PWM signal to drive the adjusted semiconductor to increase or decrease the temperature of the water in the sheath.

[0052] The above-mentioned power consumption control method of the children's physical cooling device is applied to the power consumption control system of the children's physical cooling device; the power consumption control system of the children's physical cooling device includes a central processing unit, a temperature sensor, a first evaporative condenser, a water tank and a sheath; the temperature sensor is located between the first evaporative condenser and the water tank; the temperature sensor is connected to the central processing unit; and the water tank is connected to the sheath. Power consumption control of the children's physical cooling device. The power consumption control method of the children's physical cooling device of the present application collects the current water temperature of the first evaporative condenser through the temperature sensor, and adjusts the frequency and duty cycle of the PWM signal in real time according to the temperature difference between the current water temperature and the set temperature, so as to adjust the output power of the semiconductor to increase or decrease the temperature of the water in the sheath, thereby realizing the real-time regulation of the control frequency and duty cycle of the semiconductor through the temperature difference between the current water temperature and the set temperature. At the same time, by improving the water path, the cooling and heating efficiency and the heat dissipation efficiency are greatly improved, which can greatly reduce the power consumption of the semiconductor, thereby improving the endurance of the system.

[0053] The above exemplary steps of the embodiment of the present application are described below with reference to specific examples:

[0054] S101, collecting the current water temperature of the first evaporative condenser through a temperature sensor, and calculating the temperature difference between the current water temperature and the set temperature through a central processing unit.

[0055] In the embodiment of the present application, the set temperature is a pre-set temperature. The current water temperature of the first evaporative condenser is collected by a temperature sensor located between the first evaporative condenser and the water tank. After obtaining the current water temperature, the central processing unit calculates the temperature difference between the current water temperature and the set temperature for subsequent processing. For example, Figure 2 As shown, through Figure 2 The evaporative condenser in the upper right corner, i.e. the first evaporative condenser, collects the current water temperature, as well as Figure 3 As shown, the current water temperature is collected for subsequent processing.

[0056] S102, through the central processing unit, based on the temperature difference between the current water temperature and the set temperature, the frequency and duty cycle of the PWM signal are adjusted in real time.

[0057] It should be noted that the semiconductor control can be composed of two driver chips, four MOS tubes and other peripheral devices. The input signal is two PWM signals with the same frequency and opposite polarity. The output polarity and output frequency of the semiconductor can be controlled by the control signal.

[0058] In the embodiment of the present application, the PWM signal is used to control the output polarity and output frequency of the semiconductor. Specifically, the PWM signal can control the output polarity (or supply voltage) and output frequency of the semiconductor through the control signal. The central processing unit can adjust the frequency and duty cycle of the PWM signal in real time according to the temperature difference between the current water temperature and the set temperature in step S101. For example, Figure 3 As shown, the frequency and duty cycle of the PWM signal are adjusted differently according to the temperature difference between the current water temperature and the set temperature.

[0059] S103 , adjusting the output power of the semiconductor based on the frequency and duty cycle of the PWM signal to drive the adjusted semiconductor to increase or decrease the temperature of the water in the sheath.

[0060] In the embodiment of the present application, the output power of the semiconductor is adjusted according to the frequency and duty cycle of the PWM signal regulated in step S102 to drive the adjusted semiconductor to increase or decrease the temperature of the water in the sheath.

[0061] It should be noted that the water temperature measured in this application is not the water in the water tank, but the water temperature near the first evaporative condenser. The different placement of the temperature sensor makes the measured water temperature more accurate and better reflects the heat dissipation situation. In addition, this application does not heat and cool the water in the water tank, but rather the water in the jacket. The jacket contains less water, thus improving the heating and cooling efficiency.

[0062] Therefore, by adjusting the frequency and duty cycle of the PWM signal in real time according to the temperature difference between the current water temperature and the set temperature, the output polarity (or power supply voltage) and frequency at both ends of the semiconductor are dynamically adjusted based on the water temperature feedback. There is no need to frequently start and stop the semiconductor, which can greatly reduce the power consumption of the semiconductor, increase the heating and cooling rate, and increase the endurance in the event of a power outage.

[0063] The power consumption control method of a children's physical cooling device provided in the embodiment of the present application is applied to the power consumption control system of a children's physical cooling device; the power consumption control system of the children's physical cooling device includes a central processing unit, a temperature sensor, a first evaporative condenser, a water tank and a sheath; the temperature sensor is located between the first evaporative condenser and the water tank; the temperature sensor is connected to the central processing unit; and the water tank is connected to the sheath. Power consumption control of a children's physical cooling device. The power consumption control method of a children's physical cooling device of the present application collects the current water temperature of the first evaporative condenser through a temperature sensor, and adjusts the frequency and duty cycle of the PWM signal in real time according to the temperature difference between the current water temperature and the set temperature, so as to adjust the output power of the semiconductor to increase or decrease the temperature of the water in the sheath, thereby realizing real-time regulation of the control frequency and duty cycle of the semiconductor by the temperature difference between the current water temperature and the set temperature, and at the same time greatly improving the cooling and heating efficiency and the heat dissipation efficiency by improving the water path, which can significantly reduce the power consumption of the semiconductor, thereby improving the endurance of the system.

[0064] Further, such as Figure 4 As shown, the step S102 in the above embodiment of "regulating the frequency and duty cycle of the PWM signal in real time based on the temperature difference between the current water temperature and the set temperature" may specifically include the following steps:

[0065] S401, comparing the temperature difference with a preset temperature difference range, and determining a corresponding adjustment parameter according to the comparison result.

[0066] In the embodiment of the present application, the temperature difference interval is a pre-set temperature difference interval. The temperature difference between the current water temperature and the set temperature is compared with the temperature difference interval to obtain a comparison result. The corresponding adjustment parameter is determined based on the comparison result for subsequent processing. Among them, the adjustment parameter can be understood as a proportional parameter (the maximum value is 100%).

[0067] It's important to note that smaller temperature differences require smaller adjustment parameters, while larger temperature differences require larger adjustment parameters. Different adjustment parameters correspond to different PWM signal frequencies and duty cycles. Simply put, a smaller temperature difference indicates that the semiconductor's cooling instructions don't require a high output power. A smaller adjustment parameter and a larger temperature difference indicate a need for higher cooling or heating power.

[0068] Optionally, a mapping table between different temperature difference intervals and adjustment parameters is obtained; in response to the temperature difference being within the target temperature difference interval, a corresponding adjustment parameter is determined from the mapping table. For example, if the first temperature difference interval is greater than or less than 5°C (representing the first temperature difference interval), the adjustment parameter corresponding to the first temperature difference interval may be 99%, i.e., a mapping table is formed between the two.

[0069] S402 , regulating the frequency and duty cycle of the PWM signal in real time based on the adjustment parameters.

[0070] In the embodiment of the present application, the frequency and duty cycle of the PWM signal are adjusted in real time based on the adjustment parameters determined in step S401. Figure 3 As shown, when the temperature difference between the current water temperature and the set temperature is greater than or less than 5°C, it is in the first temperature difference range. At this time, the frequency and duty cycle of the PWM signal can be reduced by 99%. The same applies to other temperature difference ranges. No further details will be given here. Figure 3 .

[0071] Furthermore, the ambient temperature is collected by a temperature sensor; the frequency and duty cycle of the PWM signal are adjusted in real time based on the ambient temperature and temperature difference. Figure 3 As shown, when adjusting the frequency and duty cycle of the PWM signal in real time, the influence of the ambient temperature can also be considered, and the ambient temperature and temperature difference can be introduced to adjust the frequency and duty cycle of the PWM signal in real time.

[0072] Figure 5 This is a structural block diagram of a power consumption control system of a children's physical cooling device according to an embodiment of the present application. The power consumption control system 500 of the children's physical cooling device includes a central processing unit 1, a temperature sensor 2, a first evaporative condenser 3, a water tank 4 and a sheath 5.

[0073] The temperature sensor 2 is located between the first evaporative condenser 3 and the water tank 4; the water tank 4 is connected to the sheath 5; and the temperature sensor 2 is connected to the central processing unit 1. For example, Figure 2 As shown (some devices are not shown).

[0074] The temperature sensor 2 is used to collect the current water temperature of the first evaporative condenser 3 .

[0075] The central processing unit 1 is used to calculate the temperature difference between the current water temperature and the set temperature; and based on the temperature difference between the current water temperature and the set temperature, to adjust the frequency and duty cycle of the PWM signal in real time; the PWM signal is used to control the output polarity and output frequency of the semiconductor.

[0076] The central processing unit 1 is further configured to adjust the output power of the semiconductor based on the frequency and duty cycle of the PWM signal, so as to drive the adjusted semiconductor to increase or decrease the temperature of the water in the sheath 5 .

[0077] Furthermore, the power consumption control system 500 of the children's physical cooling device includes a one-way valve, a first water pump, and a second evaporative condenser. The water tank 4 is connected to the one-way valve and is connected to the first water pump through the one-way valve; the second evaporative condenser is placed between the first water pump and the sheath 5. For example, Figure 2 As shown, the evaporative condenser in the lower left corner represents the second evaporative condenser, and the water pump in the lower left corner represents the first water pump.

[0078] The water tank 4 is used to fill the sheath 5 with water through the one-way valve, the first water pump and the second evaporative condenser in sequence. Furthermore, the power consumption control system 500 of the children's physical cooling device includes a pressure sensor. The pressure sensor is placed at the inlet of the sheath 5. For example, Figure 2 As shown, the pressure sensor in the lower left corner is placed at the inlet of the sheath 5.

[0079] The pressure sensor is used to detect the pressure information of the second evaporative condenser.

[0080] It should be noted that the pressure sensor is placed at the inlet of the sheath 5 so that the pressure can be measured more accurately.

[0081] Furthermore, the power consumption control system 500 of the children's physical cooling device includes a three-way connection. The three-way connection is placed between the water tank 4 and the sheath 5, and is connected to the water tank 4, the sheath 5 and the first water pump. For example, Figure 2 As shown, the tee in the upper right corner is placed between the water tank 4 and the jacket 5, and is correspondingly connected to the water tank 4, the jacket 5 and the first water pump, that is, the water tank 4, the jacket 5 and the first water pump can be connected in three connection directions.

[0082] The three-way valve is used to connect to the first water pump in response to the pressure information reaching a preset pressure threshold, so as to form a treatment circulation water circuit to cool and heat the water in the sheath 5.

[0083] Furthermore, the water tank 4 is also used to transfer the remaining water except the jacket 5 to the first evaporative condenser 3 for heat dissipation.

[0084] In general, Figure 2 Symbolizes the improved waterway of this application, such as Figure 2 As shown, the upper right water channel is the heat dissipation part, and the lower left water channel is the cooling and heating part. At the beginning, the water in the water tank 4 passes through the one-way valve, water pump, and evaporator / condenser to fill the sheath 5. When the pressure at the inlet of the sheath 5 detected by the pressure sensor reaches the preset pressure threshold, the three-way switch is connected to the water pump to form a treatment circulation water channel. This water channel consumes very little water and is equipped with good thermal insulation materials. It only requires very little power consumption to achieve the purpose of rapid temperature increase and decrease. At the same time, the remaining water volume increases, making the heat dissipation efficiency higher.

[0085] Thus, through Figure 2 As shown in the improved water path, the present application still reduces power consumption, improves the heating and cooling rate and heat dissipation efficiency, thereby increasing endurance in the event of a power outage.

[0086] The power consumption control system 500 of the children's physical cooling device of the present application includes a central processing unit 1, a temperature sensor 2, a first evaporative condenser 3, a water tank 4 and a sheath 5; the temperature sensor 2 is located between the first evaporative condenser 3 and the water tank 4; the temperature sensor 2 is connected to the central processing unit 1; and the water tank 4 is connected to the sheath 5. Power consumption control of the children's physical cooling device. The power consumption control system of the children's physical cooling device of the present application collects the current water temperature of the first evaporative condenser through the temperature sensor, and adjusts the frequency and duty cycle of the PWM signal in real time according to the temperature difference between the current water temperature and the set temperature, so as to adjust the output power of the semiconductor to increase or decrease the temperature of the water in the sheath, thereby achieving real-time regulation of the control frequency and duty cycle of the semiconductor through the temperature difference between the current water temperature and the set temperature. At the same time, by improving the water path, the cooling and heating efficiency and the heat dissipation efficiency are greatly improved, which can significantly reduce the power consumption of the semiconductor, thereby improving the endurance of the system.
