Description

Intelligent control method and system for intelligent parameters of infrared physiotherapy equipment Technical Field The application belongs to the technical field of intelligent control of infrared physiotherapy equipment, and particularly relates to an intelligent parameter control method and system of infrared physiotherapy equipment. Background Infrared physiotherapy equipment plays an important role in modern rehabilitation therapy, and acts on a human body through accurate heat energy, so as to relieve uncomfortable symptoms, accelerate tissue repair and promote rehabilitation of patients. However, in practical clinical application, especially when facing increasingly diversified patient groups, how to realize accurate and adaptive control of the operation parameters of the infrared physiotherapy equipment is always a technical problem to be solved. The conventional infrared physiotherapy equipment generally adopts preset fixed operation parameters, and the control mode of the one-knife cutting is difficult to fully adapt to physiological differences among individuals. When there is a significant difference in individual characteristics of the patient (such as skin type, subcutaneous fat thickness, thermal sensitivity, etc.), or the experience of the operator is insufficient, this stiff control often results in a less than ideal therapeutic effect and may even cause safety hazards. To remedy these deficiencies, clinical practice often requires manual intervention by experienced medical personnel, but this presents new problems such as reduced accuracy of the treatment data records and excessive reliance on the personal experience of the operator, making the treatment process difficult to standardize and quantify. In order to cope with the inherent inconsistencies in the control and optimize the treatment process, some experienced medical personnel have developed a set of strategies in long-term practice that are manually adjusted according to the patient's real-time response and subjective comfort. However, while such frequent manual intervention appears to improve treatment efficiency and patient comfort over a short period of time, it introduces a new, more concealed problem in that significant deviations occur between the recorded treatment parameters inside the device and the output parameters actually applied to the patient. The root cause is that the internal data recording systems of many infrared physiotherapy devices are mainly designed to record preset treatment plan parameters and raw data acquired by sensors, rather than precisely tracking specific values and time points of each manual intervention. This distortion of data, in turn, severely impacts objective assessment of the therapeutic efficacy of different patient populations, also hampers standardized management and optimization of treatment protocols, making clinical studies or improving treatment protocols based on historical data exceptionally difficult. In view of the above, in the face of the increasingly diverse patient groups, the fluctuation of therapeutic effects and safety risks caused by different experience levels of operators, and the inherent limitations of the traditional manual parameter adjustment method, the existing infrared physiotherapy devices are urgent to need a system capable of sensing individual differences in real time, intelligently predicting skin thermal responses, and adaptively adjusting core control parameters. The system aims to ensure that under different treatment scenes, the optimal curative effect can be achieved, the safety of a patient can be ensured to the greatest extent, and the simplification of operation and the standardization of the treatment process are realized. In view of the above, there is a need in the art for improvements. Disclosure of Invention In view of the shortcomings of the prior art, the application provides an intelligent control method and an intelligent control system for intelligent parameters of infrared physiotherapy equipment, which can realize the beneficial effects of intelligent self-adaptive control of the parameters of the infrared physiotherapy equipment by collecting physiological characterization data in real time and dynamically adjusting PID control parameters according to the physiological characterization data, effectively solve the problems that the traditional equipment cannot adapt to individual differences, has poor treatment effect and has potential safety hazards, and remarkably improve individuation, effectiveness and safety of treatment.
