The system realizes body fluid test strip image acquisition, color recognition and health risk assessment through a hierarchical structure of body fluid detection device, host computer processing unit and cloud analysis unit. Background Technology
[0002] Lung diseases are characterized by insidious onset and inconspicuous early symptoms. Current screening methods mostly rely on imaging examinations or blood tests, which are costly and cannot meet the needs of long-term, high-frequency health monitoring.
[0003] Colorimetric detection methods based on changes in bodily fluid biochemical indicators offer advantages such as being non-invasive and convenient. However, existing test strip methods typically rely on manual colorimetric analysis to interpret results, which suffers from significant subjective errors and poor repeatability.
[0004] Some detection devices integrate image acquisition, color recognition, and risk analysis functions into the terminal device, resulting in complex device structure, difficulty in algorithm updates, and difficulty in achieving model iteration and integrated analysis of multiple detection data.
[0005] Therefore, it is necessary to provide a detection system with a clear division of labor and reasonable separation of functions to improve the stability of image acquisition and the accuracy of risk assessment. Summary of the Invention
[0006] I. Purpose of the Invention The purpose of this invention is to provide a detection system based on color recognition of multi-body fluid test strips. Through a layered structural design, the system separates image acquisition, color recognition and risk assessment functions, thereby improving detection stability and system scalability. Technical solution

It is used to receive the test strip color image captured by the camera, locate the color development area and extract color features from the image, and generate body fluid detection results and risk classification information. The cloud-based analysis unit is communicatively connected to the host computer processing unit and is used to receive the risk classification information and perform a comprehensive health risk assessment based on a preset analysis model.
[0008] The test strip slot is equipped with a guide structure to limit the insertion direction and posture of the test strip.
[0009] The camera is fixed in position relative to the test strip tray.
[0010] The housing is a closed structure, and the imaging acquisition area forms a light-shielding cavity.
[0011] The host computer processing unit locates the color development area of the test strip and calculates the color parameters.
[0012] The cloud-based analysis unit performs trend analysis on multiple test data from the same subject. Beneficial effects
[0013] Compared with the prior art, the present invention has the following technical effects: (1) Improve image acquisition consistency through the design of guiding structure and fixed imaging structure; (2) By using a light-shielding cavity structure, the impact of ambient light changes on the detection results is reduced; (3) Improve the objectivity and repeatability of detection results through automatic color feature extraction; (4) By using a hierarchical structure design, the image acquisition and risk assessment functions are separated, reducing the complexity of the terminal structure; (5) Improve the stability of risk assessment results by analyzing the trend of multiple test data.
