Fetal heart monitoring system, equipment and method based on multi-dimensional channel signal processing

Abstract

The invention provides a fetal heart monitoring system, equipment and a method based on multi-dimensional channel signal processing. The system comprises: a hardware platform which comprises a sound vibration sensor and is used for collecting a fetal heart data signal; an application system which is in communication connection with the hardware platform, acquires the fetal heart data signal, transmits the fetal heart data signal to a cloud computing platform and controls the hardware platform to work; and a cloud computing platform used for carrying out fetal heart sound and fetal heart rate extraction on the fetal heart data signal, carrying out fetal heart positioning according to the fetal heart sound and returning a positioning result to the application system. A Doppler ultrasonic probe is replaced with the sound vibration sensor, so that the fetal heart rate monitoring accuracy is improved, and the medical cost is greatly reduced while the accuracy is improved; fetal heart positioning and data storage are carried out through the cloud, and remote monitoring of medical staff is also facilitated; long-time data acquisition, real-time detection and abnormal real-time reporting can be realized through the cloud.

Description

technical field [0001] The present invention relates to the field of measurement technology, in particular to a fetal heart rate monitoring system, equipment and method based on multi-dimensional channel signal processing. Background technique [0002] Fetal heart sounds differ from adult heart sounds in three ways: [0003] The fetal heart rate is higher than the adult heart rate: the adult heart rate is between 60 and 100 BPM [9], but the fetal heart rate is 100 to 160 BPM. Therefore, the design will need to provide higher resolution in the time domain. [0004] Fetal heart sounds contain more noise: Because the fetal heart is deeply buried in the pregnant woman's abdomen, the fetal heart sound is much more attenuated than the adult heart sound. In addition, the fetal heart is not as powerful as the adult heart, which makes the fetal heart sound less audible. To make matters worse, fetal blood circulation and organ activity can add noise to the fetal heart sounds. Ther...

Problems solved by technology

Although it is expected to achieve high-quality, high-sensitivity, low-power consumption, low-cost, harmless to the human body, and easy-to-operate fetal heart monitors, the problem in actual products is to rely on ultrasonic transmission and reception to detect sound to help User looking for fetal heartbeat

However, when the fetal heartbeat is weak or the external environment is too noisy, it will be more difficult to find the fetal heartbeat, causing users to be unable to quickly and accurately find the fetal heartbeat position and hear the fetal sound
