Description

Technical Field

[0001] The invention relates to the technical field of therapeutic apparatus optimization, and in particular to an infrared low-frequency magnetic pulse therapeutic apparatus optimization system based on feedback regulation. Background Art

[0002] The infrared low-frequency magnetic pulse therapeutic apparatus optimization system based on feedback regulation is a system that optimizes the infrared low-frequency magnetic pulse therapeutic apparatus by means of feedback regulation.

[0003] Among the existing similar solutions, for example, CN115252117B is an intense pulsed light therapy device and energy monitoring method that can monitor the luminous energy of a light source. This solution aims to solve the technical problem that traditional sensors are easily saturated due to excessive intense pulsed light energy, and the existing technology relies on empirical records or electrical parameter estimation and cannot reflect the actual light energy in real time. This solution first captures part of the light signal from the intense pulsed light source through a small aperture light sampling hole, and combines a filter and a multi-segment cavity to significantly attenuate the light signal, so that the therapy device is adapted to the measurement range of the photodetector, avoiding the technical effect of sensor saturation. In addition, by pre- First, the environmental noise value is collected, the background interference is dynamically eliminated, and the effective light signal is integrated and calculated to achieve the technical effect of accurate energy calibration. Finally, when the light source decays, the light source output is adjusted in real time according to the fitting function to achieve the technical effect of ensuring that the actual luminous energy is always consistent with the set value. However, there is physical aging of the device, such as electrode loss and spectral shift, which may exceed the compensation range of dynamic calibration, resulting in irreversible decline in energy output or wavelength shift, affecting the long-term use of the therapeutic device. In addition, there is a technical problem that the calibration process requires reliance on professional equipment or technicians, and improper operation by ordinary users may cause calibration failure.

[0004] For example, CN116602760B is an intelligent automatic intense pulsed light therapy device. This solution aims to solve the technical problems of incomplete skin condition monitoring, cumbersome manual adjustment, unstable treatment effect, insufficient skin temperature management and burn risk of existing equipment. This solution first achieves the technical effect of detailed analysis of skin condition by calculating the thickness of skin hair, hair follicle size, and the ratio of pits and protrusions. In addition, multi-level intense pulsed light therapy is adopted to automatically adjust the range and intensity of intense pulsed light according to skin condition data, so as to achieve the technical effect of improving treatment accuracy without manual operation. Finally, the therapy device has temperature monitoring, cooling and emergency treatment functions, so as to achieve the technical effect that the skin will not overheat during treatment and the safety of treatment is improved. However, there are technical problems that the use of image processing technology to monitor temperature through skin and hair status will have large errors, and the image acquisition quality is limited by factors such as lighting conditions, skin color, hair density, etc., which seriously affects the accuracy of temperature feature recognition. In addition, there is a technical problem that if the temperature feedback and adjustment of the temperature monitoring and cooling functions are delayed, it may still cause temporary skin overheating.
