Embodiment Construction

[0018] The present invention will be further elaborated below in conjunction with accompanying drawing:

[0019] Such as figure 1 As shown, the present invention is a heart sound monitoring device, which is arranged on a car seat belt 1, and a heart sound pick-up probe array 2 composed of more than four heart sound pick-up probes is installed in a deformable elliptical sound-proof cavity 3 . The heart sound pickup probe is made of piezoelectric material and has a built-in operational amplifier. The function of the array form mainly has the following two aspects: on the one hand, the contact area between the probe and the driver's heart area is increased, and the sensitivity, resolution and signal-to-noise ratio of the sensor are further enhanced; on the other hand, due to the difference in sampling space and time, The rear end can reduce the influence caused by position change or movement through the fusion algorithm; the heart sound pickup probe array 2 is placed in the def...

Abstract

The invention relates to a heart sound intelligent monitoring device for vehicle active safety. The heart sound intelligent monitoring device mainly comprises a heart sound pickup probe array, a signal processing circuit, an indication lamp, a lithium battery and a sound insulation cavity with a nylon sleeve tape; the heart sound intelligent monitoring device is installed on a vehicle safety belt and can be adjusted vertically along the safety belt. The bottoms of heart sound pickup probes in the device are padded with memory materials, and the heart sound pickup probes are arranged in an arrayed manner and arranged in the sound insulation cavity capable of being deformed according to contact faces. By means of the heart sound intelligent monitoring device, heart physical conditions of a driver can be monitored in real time in the traveling process; meanwhile, the heart sound intelligent monitoring device can be fused with other driver fatigue detection systems and other active safety systems; the reliability of a vehicle traveling safety monitoring system is further improved; and the heart sound intelligent monitoring device is of positive significance in crowds such as advanced-age vehicle drivers and vehicle drivers with potential heart diseases.

Description

technical field [0001] The invention relates to a heart sound monitoring device, in particular to an intelligent heart sound monitoring device for active safety of automobiles. Background technique [0002] At present, with the increase of research results related to heart sound feature extraction and analysis, heart sound sensors occupy an increasing proportion in medical and personal healthcare related fields. At the same time, in order to effectively solve the problem of automobile driving safety, automobile active safety solutions that make full use of new technologies are gradually receiving more and more attention. Among them, the driver fatigue detection technology represented by the driver's physiological state detection is a highly reliable application mode today. In recent years, with the aging trend of the population, car drivers also have aging problems. Among them, there is a certain proportion of heart disease patients. Once a heart attack occurs while driving...
