[0016] The technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0017] In this article, the term "comprising" is intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the sentence "comprising..." do not exclude the presence of other identical elements in the process, method, article or device that includes the elements.

[0018] In a first aspect, this embodiment discloses a method such as Figure 1 The device for automatically adjusting the heating temperature based on the temperature detection result shown includes: A power supply unit (not shown in the figure) configured to provide power; An MCU unit 110 configured as a core control; a temperature detection unit 120 configured to detect an ambient temperature; a display execution unit 130 configured to display as an operating parameter; An input execution unit 140 configured to serve as a control key; and A heating unit 150 configured to generate heat and perform target temperature monitoring; Among them, the power supply unit, the temperature detection unit 120 , the display execution unit 130 , the input execution unit 140 and the heating unit 150 are respectively connected to the MCU unit 110 .

[0019] In this embodiment, the heating unit 150 includes a heating sheet 151 for generating heat and an NTC temperature sensor 152 for monitoring the temperature of the human body surface and the heating sheet. Among them, the NTC temperature sensor 152 is built into the heating sheet inside the heating suit close to the skin, and uses a non-invasive temperature sensor NTC thermistor (10K-B3435) to accurately measure the temperature of the human body surface and the heating sheet. The heating sheet 151 (i.e., the heating material) can be, but is not limited to, efficient and safe heating materials such as flexible carbon fiber, graphene or conductive fabric, and the heating sheet 151 is evenly distributed in the key warm-keeping areas (such as the back, chest, knees, etc.) of the corresponding carrier (i.e., the heating suit). In order to ensure automatic adjustment and control, the heating sheet 151 is connected to the switch circuit 153, and the switch circuit 153 is controlled and connected to the MCU unit 110. Specifically, if Figure 2As shown, the switch circuit 153 includes a power switch MOS tube (Q1, Q2, Q3) of model AO3400 and resistors (R4, R5, R6) at corresponding positions. For example, a switch circuit composed of the power switch MOS tube Q1 and the resistor R4, the drain of the power switch MOS tube Q1 is connected to the negative electrode of a heating plate 151, the power switch MOS tube and the heating plate form a loop, the source of the power switch MOS tube Q1 is grounded, and the source of the power switch MOS tube Q1 is connected to the 1st pin of the resistor R4, the 2nd pin of the resistor R4 is connected to the gate of the power switch MOS tube Q1, and the gate of the power switch MOS tube Q1 is connected to the control pin of the MCU unit 110.

[0020] Replay Figure 2 As shown, in this embodiment, the MCU unit 110 uses an 8-bit single-chip microcomputer MCU, specifically a chip model FT61F145-TRB. The temperature detection unit 120 uses a highly sensitive, highly integrated digital infrared temperature sensor (GD60933C), which is installed outside the window of the switch controller outside the heating suit, so that the temperature measurement window can easily sense the outside temperature and is used to detect ambient temperature changes in real time. Note: GD60933C is a digital infrared temperature sensor for non-contact temperature measurement, with a built-in low-noise amplifier and a high-precision 24-bit ADC. It also integrates a high-precision body temperature algorithm and has the characteristics of high integration, high anti-interference, high reliability, and high precision. Figure 2 In the embodiment, the display execution unit 130 and the input execution unit 140 are configured to display the current working status, remaining power and other information to the user through LED indicators, vibration feedback or a small display screen, and in the technical implementation, built-in over-temperature protection, short-circuit protection and battery power monitoring functions are provided to ensure safety during use. It should be noted that the specific circuit structure and connection relationship of the MCU unit 110, the temperature detection unit 120, the display execution unit 130 and the input execution unit 140 are described in detail in Figure 2 As shown in the text, this text will not be repeated here.

[0021] Furthermore, the MCU unit 110 automatically adjusts the PWM heating ratio of the G pole through the difference algorithm of the temperature setting and the ambient temperature, and the unit 110 then controls the temperature through the PID closed-loop algorithm to make the automatic constant temperature more stable and reliable. That is, the MCU unit receives the temperature data fed back by the temperature detection unit and the heating unit, calculates the required heating power according to the preset PID closed-loop algorithm, and controls the heating unit to work according to the heating power to output the temperature.

[0022] Specifically, the PID closed-loop algorithm is: according to the difference between the human body surface temperature and the ambient temperature fed back by the heating unit, and the set temperature corresponding to the user's comfort preference (which can be preset through the mobile phone APP or the button on the clothing), the working state of the heating unit is adjusted. For example, when the ambient temperature is low and the human body temperature drops, the heating power is increased; otherwise, the heating is reduced or stopped. The PID control algorithm (implemented by the single-chip main control MCU + program) is used to make the output temperature more stable.

[0023] For PID, PID is the abbreviation of Proportional, Integral, and Differential. As the name implies, the PID control algorithm is a control algorithm that combines the three links of proportion, integration, and differentiation. It is the most mature and widely used control algorithm in continuous systems. This control algorithm appeared in the 1930s and 1940s and is suitable for occasions where the model of the controlled object is not clearly understood. Both actual operation experience and theoretical analysis have shown that when this control law is used to control many industrial processes, relatively satisfactory results can be obtained. The essence of PID control is to perform calculations based on the input deviation value according to the functional relationship of proportion, integration, and differentiation, and the calculation results are used to control the output. In industrial processes, the ideal PID control law for continuous control systems is: , where Kp is the proportional gain, Kp is inversely related to the proportionality; Tt is the integral time constant; TD is the differential time constant; u(t) is the output signal of the PID controller; e(t) is the difference between the given value r(t) and the measured value. PID combines the functional relationship of proportion, integration and differentiation. The combination of these three algorithms can effectively correct the temperature deviation of the controlled heating plate, so that it can reach a stable heating state. PID control, when the control deviation input is a step signal, immediately produces the effects of proportional and differential control. Since the rate of change is very large at the instant of the deviation input, the differential control effect is very strong, and then the differential control effect rapidly decays, but the integral effect becomes larger and larger until the static error is finally eliminated. PID control combines the three effects of proportion, integration and differentiation, which can not only speed up the system response speed, reduce oscillation, overcome overshoot, but also effectively eliminate static error. The static and dynamic quality of the system is greatly improved, so the PID controller has been most widely used in temperature control.

[0024] The topological principle of the PID closed-loop algorithm adopted in this embodiment is as follows: Figure 3 As shown, correspondingly, the adjustment parameters of the PID closed-loop algorithm of this embodiment are shown in Table 1, in which (to is the outdoor sensor temperature, ti is the human body surface sensor temperature (that is, the human body surface temperature detected by the NTC temperature sensor); t is the set temperature.

In technical implementation, the function of intelligently adjusting the heating power and automatically entering the sleep mode when not necessary can be configured to maximize the battery life.
