In an example, taking the preset temperature information as 25 ℃ and the preset temperature threshold as 0.5 ℃ as an example, if the current temperature information is 27 ℃, the controller sends a first temperature adjustment instruction, where the first temperature adjustment instruction is used to instruct the refrigeration sheet to operate to cool the temperature-insulating cavity. If the current temperature information is 23 ℃, the controller sends a second temperature adjusting instruction, wherein the second temperature adjusting instruction is used for indicating the refrigerating sheet to work, and specifically, the cold and hot surfaces of the refrigerating sheet can be alternated to heat the heat insulation cavity.
In some embodiments of the present application, the state of the cooling fin is controlled to be the first state when the difference between the current temperature information and the preset temperature information is smaller than the preset temperature threshold.
The first state is a non-working state, namely the refrigerating sheet is in an idle state.

the processing module is in communication connection with the receiving module, receives the light which is not absorbed by the part to be detected, analyzes the light which is not absorbed by the part to be detected, and determines the concentration of the hemoglobin of the part to be detected.
4. The system of claim 2, wherein the temperature-insulated chamber is a ceramic material.
5. The system of claim 1, wherein the controller is further configured to: and under the condition that the difference value between the current temperature information and the preset temperature information is smaller than the preset temperature threshold value, controlling the state of the refrigerating sheet to be a first state, wherein the first state is a non-working state.
6. The system of any one of claims 1-2, wherein the chilling plates are a semiconductor material.
7. The system of any of claims 1-2, wherein the emitting module is an LED lamp.
8. A temperature control method applied to the temperature control system according to any one of claims 1 to 7, the method comprising:
acquiring current temperature information of a transmitting module;
and under the condition that the difference value between the current temperature information and preset temperature information is greater than or equal to a preset temperature threshold value, controlling a refrigerating sheet to adjust the current temperature information so that the difference value between the current temperature information and the preset temperature information is smaller than the preset temperature threshold value, wherein the preset temperature information is determined based on the wavelength of the light emitted by the emitting module.
9. The method of claim 8, wherein after the obtaining current temperature information of a transmitting module, the method further comprises:
irradiating the part to be detected with the light emitted by the emitting module;
after the control refrigeration piece adjusts the current temperature information, the method further comprises:
acquiring transmission information of the light irradiated on the part to be detected;
and analyzing the transmission information to determine the concentration of the hemoglobin of the part to be detected.
10. The method of claim 8, wherein after the obtaining temperature information of the light emitted by the emitting module, the method further comprises:
and under the condition that the difference value between the current temperature information and the preset temperature information is smaller than the preset temperature threshold value, controlling the state of the refrigerating sheet to be a first state, wherein the first state is a non-working state.
