Wireless ECG signal acquisition and analysis system

1、 Product Overview

BD-C-2 typeWireless ECG signal acquisition and analysis systemIt is an ECG signal acquisition and analysis system developed by Peking University based on advanced technologies from disciplines such as biofeedback, cognitive psychology, education, electrocardiography, and cardiovascular and cerebrovascular science. Using the principles of biofeedback and heart rate variability theory, the system utilizes portable and reliable ECG intelligent sensing technology and professional algorithms, and employs data analysis and artificial intelligence technology. It is a set of ECG physiological data acquisition, experimental analysis, and auxiliary testing systems based on biofeedback research.

2、 Product principle description

Wireless ECG signal acquisition and analysis systemWe adopt internationally advanced medical precision electrocardiogram signal sensing systems to accurately collect electrocardiogram signals, perform signal acquisition and analysis of electrocardiogram, heart rate, and heart rate variability, and effectively conduct time-domain, frequency-domain, and time-frequency domain analysis of electrocardiogram signals through Fourier transform (FFT) and other analysis methods and algorithms.

The system uses quantitative measurement and analysis methods such as heart rate variability (HRV), LF/HF, scatter plots, and average heart rate, respiratory rate, and cardiac capacity to collect electrocardiogram data. It conducts psychological, cognitive, and multi domain analysis of electrocardiogram signals in the time domain, frequency domain, and time-frequency domain, as well as statistical analysis and exploratory experimental research. At the same time, portable neural biofeedback experiments can be conducted to assist in regulating and training cognitive ability, anti-interference ability, thinking ability, and emotional self-regulation ability.

3、 Product Features

The system sensor adopts an internationally advanced third-generation ECG biological signal detection and processing system with medical accuracy, a digital wireless sensing system, which is portable, high-precision, and reliable.

The system has two forms: testing experiment collection and self-designed testing experiment collection and analysis. It conducts research on the collection and analysis of central electrical signals during experimental and training projects.

3. It is possible to study the changes in the sympathetic and parasympathetic nervous systems of individuals in specific experimental environments and activity states, analyze their physical and mental health status, and emotional stability. Experiments such as relaxation, attention, memory, and consciousness can be conducted to correspond with electrocardiogram signals for analysis of emotions, tension, and reaction states.

4. Network based database management can conduct data research and analysis on individual development and group distribution.

5. Conduct biofeedback experiments and conduct testing and analysis research on improving autonomic nervous system regulation ability and enhancing individual stress response ability through electrocardiogram biofeedback training.

The 6 products can be used standalone or set up for multi-user use on the network, making it convenient for teachers to conduct experiments, group teaching, data analysis, teaching analysis, scientific research activities, as well as big data and electrocardiogram research for different training projects.

4、 Applicable fields of the product

The system is portable and easy to operate, and can be used as a basic experimental teaching equipment for majors such as ergonomics, human factors engineering/ergonomics, cognitive psychology, experimental psychology, medicine, physiology, aerospace safety, industrial management and safety, sports, safety ergonomics, artificial intelligence, etc. It can also be used as an experimental and research tool for learning habits and abilities in primary and secondary schools. At the same time, it is a convenient and fast experimental tool for teachers and students to carry out scientific research such as expansion and innovation experiments, stress and emotion analysis.

The system can conduct research on cultivating students' learning abilities and habits, alleviating and overcoming negative emotions such as anxiety, tension, impulsivity, depression, and improving psychological factors through testing and analysis functions. It can also provide training, testing, and treatment effect reference analysis for attention deficit hyperactivity disorder (ADHD) patients, anxiety disorders, sleep disorders, substance dependence (drug addiction, alcohol addiction), and other diseases.

In the field of sports, studying the harmony level of athletes' hearts, brains, and nervous systems through testing and analysis of functions is beneficial for improving athletes' attention ability, stress emotion management ability, reaction ability, and competitive performance.

5、 System composition

The product consists of three parts: portable electrocardiogram acquisition device, data acquisition receiving and analysis, and training system.

1. ECG acquisition equipment: This system uses highly integrated BMD101 ECG signal detection on-chip devices to complete ECG acquisition work. Compared with the traditional ECG signal acquisition system, the BMD101 has high integration, low power consumption, high signal accuracy and other technologies. It is a medical level solution for detecting and processing biological signals. It can collect biological signals in the range of microvolts to millivolts for detection, a high-resolution analog-to-digital converter (16 bits), and low input noise. Equipped with automatic detection of sensor detachment and real-time reporting of heart rate (± 1bpm).

2. Data collection and reception: wireless data transmission. Adopting hardware binding mode, allowing one-to-one wireless communication between ECG devices and compatible data acquisition receivers, automatic matching, non interfering, with a frequency of 2.4GHz.

3. Collection and Analysis System: Composed of a computer system and a software system, the collection and analysis software system is a data collection and analysis software system based on network applications, using a browser server structure to facilitate the development and classification statistical analysis of different types of teaching and experiments.
