Problems solved by technology
Although there are single-lead ECG acquisition devices on the market, they can obtain few characteristic parameters, and the collected data not only has low reliability, but also cannot reflect the heart function health of users when they are exercising or maintaining a relatively static state. Even if the existing ECG monitoring equipment can judge the user's exercise status, it will not have much application value because the accuracy of the collected data is not high enough.

Embodiment approach
[0172] Combine below Figure 1 to Figure 3 Introduce the embodiment of the present invention, specifically:
[0173] Step 1: The Bluetooth signal processing module collects ECG data through the ECG signal acquisition module, and collects the spatial attitude data through the spatial attitude acquisition module. The ECG data is processed by the Hamming window FIR digital bandpass filter to obtain the filtered ECG data. The attitude data is first processed by the median average filter algorithm, and then processed according to the extended Kalman filter algorithm to obtain the filtered spatial attitude data;
[0174] The ECG data described in step 1 are:
[0175]
[0176] u i =(U P,i ,U Q,i ,U R,i ,U S,i ,U ST,i ,U T,i ) T
[0177] u NOISE,i =(U PNOISE,i ,U QNOISE,i ,U RNOISE,i ,U SNOISE,i ,U STNOISE,i ,U TNOISE，i ) T
[0178]
[0179] Among them, M is the number of collected ECG signal groups, ECG signal collected for group i, U i Ideal ECG signal co...

The invention discloses a heart health state monitoring system and method based on bluetooth wireless communication. The system of the present invention includes an electrocardiographic signal acquisition module, a bluetooth signal processing module, a power supply management module, a space attitude acquisition module and a mobile terminal. The method of the present invention collects and filters the ECG data and spatial attitude data, calculates the correlation coefficient and judges the heart function health level data, and transmits the filtered ECG data, space attitude data and heart function health level data information to the mobile terminal through bluetooth wirelessly displayed after. The present invention can collect electrocardiographic data and spatial posture data in different motion states of the user, thereby obtaining electrocardiographic data in multi-dimensional states. The system hardware of the invention has simple and convenient structure, high integration, portability and low power consumption. The software improves the accuracy and precision of the collected data, combines different filtering algorithms to process the data, reduces the false positive rate, and can reflect the data information of the user's heart function health level.
Description
technical field [0001] The invention relates to the field of mobile medical technology, in particular to a system and method for monitoring heart health status based on Bluetooth wireless communication. Background technique [0002] With the acceleration of modern people's pace of life and the increase of work pressure, as well as the aggravation of the aging population in my country, the incidence and mortality of heart disease are increasing day by day. Heart disease has the characteristics of sudden, transient and paroxysmal. If patients with heart disease do not receive timely and effective treatment after the attack, not only the condition will aggravate, but they may even pay the price of life. Early detection, early prevention and early treatment are the three principles of heart disease prevention. In the past, heart disease patients went to the hospital for ECG testing, which was not only limited in time and activity space, but also the collected ECG signals were st...
