Problems solved by technology

Although these detection methods are quantitative in nature, they are still comprehensive evaluations of functions, which are subjective and lack in-depth and detailed analysis of the swing characteristics of balance disorders, so their application value is limited

Embodiment Construction

[0115] The implementation flow chart of the present invention is as figure 1 and figure 2 As shown, the specific implementation steps are as follows:

[0116] Step 1: The user completes various types of running actions through the treadmill. Since the four bearings of the electric treadmill are equipped with flexible array pressure sensors, people will generate various pressures after exercising on the running belt. The pressure of the four bearings The sensor feels the effect of pressure and generates eight voltage signals. After calculating these eight voltage signals, the projected position of the user's pressure center of gravity on the treadmill can be obtained, and then the sensor's position coordinates A(x 1 ,y 1 ), B(x 2 ,y 2 ), C(x 3 ,y 3 ),D(x 4 ,y 4 ),E(x 5 ,y 5 ), F(x 6 ,y 6 ),G(x 7 ,y 7 ), H(x 8 ,y 8 ), and the data D obtained from the difference between adjacent positions ab (Δx 12 ,Δy 12 ),D bc (Δx 23 ,Δy 23 ),D cd (Δx 34 ,Δy 34 ),D ad...

Abstract

The invention discloses a method for dynamically monitoring abnormal states of users of a treadmill. The method includes firstly, acquiring training data of the users of the treadmill; secondly, preprocessing the data; thirdly, extracting semantic features of the processed data by means of LDA (linear discrimination analysis); fourthly, accumulating knowledge of normal states by using the semantic features as observed quantities, in other words, training an HMM (hidden Markov model); fifthly, judging the abnormal states by the aid of the acquired model and the semantic features. The method has the advantages that the method is based on an algorithm for dynamically monitoring the abnormal states of the users of the treadmill, so that the abnormal states can be quickly and accurately monitored, purposes of training, monitoring and accumulating the knowledge of the normal states can be achieved, and the abnormal states of the users can be effectively monitored under the condition that health states of the users are unknown, and can be monitored intelligently.

Description

technical field [0001] The invention specifically relates to a dynamic monitoring method based on the abnormal state of treadmill users. According to the International Patent Classification (IPC), it belongs to the Department of Physics, Instrument Division, Calculation; Calculation, Counting, and Electronic Digital Data Processing, especially The technical field of a large group of digital computing or data processing devices or data processing methods for specific applications. Background technique [0002] Scholars at home and abroad have been exploring the detection methods for human balance dysfunction, and invented many detection methods. The traditional balance function testing method is subjective observation: Romberg’s test, also known as standing test with eyes closed, is the earliest clinically established test. Body shaking situation. In 1966, Graybie improved the simple upright test with the feet close together in the Romberg test. He began to use the single-l...
