Description

TECHNICAL FIELD

[0001] The utility model relates to signal acquisition technical field especially, it relates to a multi -source heart rate data acquisition device. BACKGROUND

[0002] Heart rate is an important vital sign for detecting human health condition, and the onset condition of most diseases is directly or indirectly related to the change of physiological signals. Heart rate monitoring provides reliable diagnosis and real-time basis for doctors. In current hospital treatment, contact devices such as finger clamp instrument, electrocardiogram, etc. are mostly used for heart rate monitoring, but the contact devices not only have low comfort, but also can cause additional harm to burn patients and infants. Therefore, the utility model adopts a non-contact method to monitor heart rate.

[0003] The technologies for non-contact heart rate monitoring mainly include radio frequency system, optical fiber sensor, computer vision and radar system, but the above monitoring technologies have their advantages and limitations. The signal emission direction of the radio frequency system is relatively divergent, and the multipath effect is relatively serious. The optical fiber sensor is greatly affected by light source fluctuation during work. The computer vision estimates vital signs through the change of skin reflection characteristics, and at the same time, the face recognition algorithm can be used to determine the identity of the target personnel, so that the patient information can be matched while monitoring. The radar system using electromagnetic technology is sensitive to the perception of the weak amplitude movement of the heart beat due to its high frequency and short wavelength characteristics.

[0004] Current research shows that in ippg (imaging photoplethysmogram) monitoring, when the target personnel is in a dark or smoke-filled environment, it will affect the camera to collect face information, and seriously it will lead to the failure to obtain face information. When multiple target personnel exchange positions in the detection range, the correspondence between the target personnel and the signal cannot be determined, resulting in errors in heart rate detection. Therefore, using the camera and radar to collect data for heart rate monitoring can achieve the purpose of matching vital sign information and user identity. UTILITY MODEL CONTENT
