Embodiment Construction

[0044] Hereinafter, an embodiment of the present invention will be described based on the drawings. It should be noted that the structures denoted by the same reference numerals in the respective drawings indicate the same structures, and description thereof will be appropriately omitted. In the present specification, reference numerals with suffixes are omitted when referring collectively, and reference numerals with suffixes are indicated when individual structures are indicated.

[0045] WiFi-based solutions have recently emerged as an alternative. Since WiFi behavior perception is based on existing communication equipment and utilizes WiFi signals widely present in the environment, it has good universality and scalability. Compared with traditional human behavior perception methods, such as computer vision perception technology, infrared perception technology, and special sensor perception technology, human behavior perception technology based on WiFi signals has non-line...

Abstract

The invention relates to an enhanced real-time respiration and heart rate monitoring and evaluation method and system based on WiFi signals. The method is a sleep vital sign monitoring scheme which islow in cost, non-invasive, extensible and capable of achieving long-term operation. Respiration and heart rate detection is enhanced by improving hardware setting, to be more specific, improving an antenna setting method based on the Fresnel zone theory, and the respiration and heart rate are monitored in real time by using offline equipment and a real-time system at the same time. Experiments results show that the method and system is high in detection precision when being used to detect the respiration and heart rate of asleep people in different postures.

Description

technical field [0001] The invention belongs to the fields of artificial intelligence and medical health, in particular a method and system for real-time monitoring of enhanced breathing and heart rate based on WiFi signals. Background technique [0002] Vital signs monitoring is extremely important to master a person's basic health status. However, many diseases in sleep can directly lead to death, such as cardiac arrest, sleep apnea, asthma and so on. A recent study showed that breathing disturbances are an important cause of SIDS during sleep. In many cases, patients with respiratory diseases have transient features only occasionally, so a long-term continuous detection device with low power consumption is extremely important. [0003] Most traditional methods use sensors to detect physiological signals, such as polysomnography and electrocardiography, which measure functions such as respiration and heart rate by attaching multiple sensors to the patient. However, these...
