Description

Technical Field

[0001] The present application relates to the technical field of smart shoes, and more specifically, to a smart shoe temperature control circuit and a temperature control method thereof. Background Art

[0002] Smart warm shoes are a new type of shoes that are equipped with a control circuit for heating the shoe body. The control circuit of smart warm shoes is generally composed of a switch device for controlling the on and off of the circuit, a battery assembly for providing electrical energy to the switch device, and a heating element for heating the shoe body. Among them, the switch device includes a switch button, a control microcontroller connected to the switch button, and a MOS tube switch for controlling the circuit to be turned on or off according to the instructions issued by the control microcontroller. When the smart warm shoes need to be heated, the switch button needs to be manually turned on to control the heating element for heating, and the temperature cannot be adaptively adjusted to ensure the preset constant temperature; the heating element generally uses ordinary tungsten wire for heating, which has the problems of slow heat conduction and relatively low efficiency, and the structure of the tungsten wire is prone to breakage and damage during strenuous exercise, which reduces the stability of the smart warm shoes.

[0003] At the same time, when the temperature of the shoes drops, you need to manually turn on the switch button again to heat the shoes to the preset temperature. The operation is very troublesome and cannot effectively maintain a constant temperature. The warm shoes need to be heated at regular intervals to keep the temperature for a certain period of time, which brings inconvenience to the use of smart warm shoes. Summary of the invention

[0004] The technical problem to be solved by the embodiments of the present application is to provide a smart shoe temperature control circuit, which effectively solves the problem that the smart shoe cannot heat automatically, has low heating efficiency, and cannot effectively maintain a constant temperature.

[0005] In order to solve the above technical problems, the embodiment of the present application provides a smart shoe temperature control circuit, which adopts the following technical solution:

[0006] A smart shoe temperature regulating circuit is installed in a smart shoe and is used to automatically regulate the temperature of the smart shoe. The smart shoe temperature regulating circuit comprises:

[0007] A power supply module and an information collection module and a heating module connected to the power supply module;

[0008] The information acquisition module includes an information processing submodule and a motion monitoring submodule and a temperature monitoring submodule connected to the information processing submodule;

[0009] The information processing submodule is used to process the motion data collected by the motion monitoring submodule and the temperature data collected by the temperature monitoring submodule from the heating module, and generate corresponding circuit control signals and temperature control signals, and control the power supply module to conduct or cut off the circuit according to the circuit control signals;

[0010] The information processing submodule is used to control the heating module to perform heating according to the temperature control signal when the circuit control signal controls the circuit of the power supply module to be turned on.

[0011] Furthermore, the heating module includes a boost circuit and a graphene heating sheet, the input end of the boost circuit is connected to the power supply module, and the output end of the boost circuit is connected to the graphene heating sheet. The boost circuit is used to boost the power input to the power supply module when the power supply module is turned on, and output the boosted current to the graphene heating sheet.

[0012] Furthermore, the graphene heating sheet is installed in the inner cavity of the smart shoe, and is used to heat the inner cavity when the power supply module is turned on. The graphene heating sheet is also connected to the temperature monitoring submodule, and the temperature monitoring submodule is used to collect the temperature of the inner cavity in real time.

[0015] Furthermore, the control switch is a MOS tube, the lithium battery is connected to the source of the MOS tube, and the boost circuit is connected to the drain of the MOS tube. When the information processing sub-module sends a circuit control signal, the lithium battery changes the output level according to the circuit control signal to control the MOS tube to turn on or off the voltage output of the boost circuit to the graphene heating plate.

[0016] Furthermore, the motion monitoring submodule is a gravity sensor, the temperature monitoring submodule is an NTC thermistor, and the information processing submodule is a Soc Bluetooth module.

[0017] Furthermore, the Soc Bluetooth module is used to read the sensor signal sent by the gravity sensor, and identify whether the temperature-regulating shoes are in a wearing state based on the sensor signal. When the temperature-regulating shoes are in a wearing state, the motion data recorded by the gravity sensor is obtained, and the motion data is converted into the circuit control signal.

[0018] Furthermore, the Soc Bluetooth module is also used to read the temperature data collected by the NTC thermistor, and calculate the temperature difference between the temperature data and a preset standard temperature value, calculate the heating time required for the heating module to heat the temperature difference at rated power based on the temperature difference, and generate the temperature control signal based on the heating time.

[0019] In order to solve the above technical problems, the embodiment of the present application also provides a smart shoe temperature adjustment method, which adopts the following technical solution:

[0021] Controlling the power supply module to turn on or off the circuit according to the circuit control signal; and

[0022] When the circuit is turned on, the heating module is controlled to perform heating according to the temperature control signal.

[0023] Furthermore, before controlling the power supply module to conduct or cut off the circuit according to the circuit control signal, the following steps are also included:

[0024] The information collection module is connected to the mobile device via Bluetooth to detect whether a switch instruction sent by the mobile device is received;

[0036] Embodiment of the smart shoe temperature control circuit of the present application

[0037] The intelligent shoe temperature control circuit of the present application comprises: a power supply module 1, an information collection module 2 and a heating module 3;

[0038] refer to Figure 1 The input end of the power supply module 1 is connected to the output end of the information acquisition module 2, the output end of the power supply module 1 is connected to the input end of the heating module 3, and the output end of the heating module 3 is connected to the input end of the information acquisition module 2.

[0039] For power supply module 1:

[0040] refer to Figure 2 The power supply module 1 includes a magnetic connector 11, a charging submodule 12, a lithium battery 13, a control switch 14 and a low voltage dropout regulator 15. The input end of the magnetic connector 11 is connected to the external power supply 10, and the output end of the magnetic connector 11 is connected to the input end of the charging submodule 12. The use of a magnetic connector can effectively prevent water, thereby improving the stability of the smart shoe; the output end of the charging submodule 12 is connected to the lithium battery 13, which is used to adjust the voltage to a corresponding voltage suitable for the lithium battery 12, and charge the lithium battery after limiting the current. By setting the charging submodule, overcurrent, overvoltage, overtemperature and other protections can be effectively achieved; the lithium battery 12 outputs current to the control switch 14 and the low voltage dropout regulator 15 In this embodiment, the control switch 14 is a MOS tube, which can be an N-type MOS tube or a P-type MOS tube. The current output by the lithium battery 12 passes through the gate of the MOS tube, and the drain of the MOS tube is connected to the heating module 3. By setting the MOS tube, the circuit on and off of the heating module 3 can be effectively controlled to automatically turn on or off the heating work of the heating module; the low-voltage difference regulator 15 is connected to the information acquisition module 2, and is used to perform low-voltage processing on the current output by the lithium battery 12, and output a stable low-voltage current to the information acquisition module 2. By setting the low-voltage difference regulator 15, the current output by the lithium battery 12 can be processed to output a stable current for the information acquisition module 2 to work.

[0041] For information collection module 2:

[0042] Continue to refer Figure 2The information acquisition module 2 includes: a motion monitoring submodule 21, a temperature monitoring submodule 22 and an information processing submodule 22. The motion monitoring submodule 21 is connected to the information processing submodule 23. One end of the temperature monitoring submodule 22 is connected to the information processing submodule 22, and the other end is connected to the graphene heating sheet 32 ​​in the heating module 3. In this embodiment, the motion monitoring submodule 21 is a gravity sensor. When the gravity sensor is subjected to pressure, the information monitoring submodule 23 can generate a corresponding electrical signal according to piezoelectric induction. At the same time, the gravity sensor has a built-in software algorithm. The gravity sensor recognizes the stepping action according to the software algorithm and responds to the instantaneous stepping action caused by the stepping action. The information processing submodule 23 is also connected to the lithium battery 12. In the present embodiment, the information processing submodule 23 is a Soc Bluetooth module, which obtains the electrical signal in the gravity sensor and uses the electrical signal as a circuit control signal to control the current output from the lithium battery 12 to the MOS tube switch. When the output level is high, the MOS tube switch is turned on, and when the output level is low, the MOS tube switch is turned off, thereby effectively identifying whether the smart shoes are in the wearing state according to the moving trajectory identified by the gravity sensor, and correspondingly controlling the opening and closing of the heating function of the smart shoes.

[0043] The temperature monitoring submodule 22 is an NTC thermistor, which monitors the temperature of the graphene heating sheet 32 ​​in real time. When the difference between the temperature of the graphene heating sheet 32 ​​and the preset standard temperature reaches the preset threshold, the Soc Bluetooth module calculates the time required for the graphene heating sheet 32 ​​of the current heating efficiency to heat the above difference according to the built-in algorithm, and generates a temperature control signal according to the time, and controls the graphene heating sheet 32 ​​to perform the heating work for the above time, thereby effectively maintaining the constant temperature of the smart shoes. For example, the preset standard temperature is 40 degrees, the monitored temperature is 34 degrees, the preset threshold is 5 degrees, and the difference is 6 degrees at this time, which has reached the preset threshold. At this time, the time required for the graphene heating sheet 32 ​​to heat 6 degrees is calculated. If the calculated time is 1min, the control circuit is turned on, so that the graphene heating sheet is heated for 1min. The above preset threshold and standard temperature can be adjusted accordingly according to actual conditions.

[0045] Continue to refer Figure 2The heating module 3 includes a boost circuit 31 and a graphene heating sheet 32. The input end of the boost circuit 31 is connected to the output end of the control switch 14, and is used to boost the current flowing through the control switch 14, so that the graphene heating sheet 32 ​​obtains a current with sufficient voltage for heating. In this embodiment, the boost circuit can adopt a DC-DC transformer circuit; the input end of the graphene heating sheet 32 ​​is connected to the output end of the boost circuit 32, and the output end is connected to the temperature monitoring submodule 22. In this embodiment, the graphene heating sheet 32 ​​is installed in the inner cavity reserved at the bottom of the smart shoe, and the temperature monitoring submodule 22 is connected to the graphene heating sheet 32 ​​to effectively monitor the temperature of the inner cavity.

[0046] This embodiment is provided with an information acquisition module 2 including a motion monitoring submodule 21, a temperature monitoring submodule 22 and an information processing submodule 23, so that the information processing submodule 23 can process the motion data collected by the motion monitoring submodule 21 and the temperature data collected by the temperature monitoring submodule 22 from the heating module 3, and generate a circuit control signal for controlling the power supply module 1 to conduct or cut off the circuit and a temperature control signal for controlling the heating module 3 to conduct heating for a predetermined time. Therefore, when the circuit is conducted, the heating module 3 can be effectively controlled to heat the temperature adjustment circuit of the smart shoe, and when the temperature monitoring submodule detects that the temperature of the heating module 3 drops, the smart shoe can be automatically controlled to heat the temperature, thereby realizing automatic temperature adjustment of the smart shoe and effectively maintaining a constant temperature.

[0051] Step S30, when the circuit is turned on, the heating module 3 is controlled to heat according to the temperature control signal.

[0052] In this embodiment, the detection of whether the circuit is turned on is performed in real time by the information processing submodule 22. Meanwhile, the circuit control signal and the temperature control signal are both digital signals.

[0053] Before step 20, the method further includes the following steps:
