Description
Technical field
Fetus-voice meter technical field is the utility model is related to, it is specifically, more particularly to a kind of based on Audio data compression
Bluetooth fetus-voice meter.
Background technology
Fetal Heart Rate refers to the number of heart of fetus bounce per minute.It is the important information normal fetus for judging fetal stress
HR Heart Rate be about 120 times per minute~160 times.When the HR Heart Rate of fetus is less than 99 times per minute or more than per minute
180 times, just belong to heart rate exception.Caused by the reason for appearance fetal heart frequency exception is due to mostly fetus ischemic, anoxic, seriously
Fetus ischemic, anoxic can cause inborn defect, inborn defect has turned at present to be influenceed one of China human mortality quality and has seriously asked
Topic.Therefore, it should pay close attention to the situation of change of fetal heart frequency.
Detected mostly using Ultrasonic Doppler techniques at present.Because the ultrasonic wave detected from ultrasonic transducer is more
General Le sound is contaminated with noise jamming, and when fetal body moves in parent, the strong and weak change of voice signal is obvious.Using to its sound
Sound carry out envelope detection, amplification shaping, then with traditional electronic counter mode heart rate measuring value when often cannot get exact value.
And either the fetus-voice meter of support bluetooth can only transmit heart rate data at present, or it can only just transmit voice data, it is impossible to realize
The real-time broadcasting of fetal heart sound is carried out in mobile phone terminal.

Processor.
Trapper, which is given, in the utility model, after the fetal heart rate signal storing greatly before menstruation of fetal rhythm probe collection eliminates industrial frequency harmonic
Component.Remaining higher hamonic wave is eliminated by bandpass filter and trapper again, audio amplification is carried out, real-time tire sound can be heard.Separately
Outside, the fetal heart rate signal after trapper is handled, which is sent into controller, carries out A/D conversions and autocorrelation calculation, calculates fetal heart frequency
It is worth and send touch display screen to show, the voice informing measured value when Fetal Heart Rate exception.Using Bluetooth technology, the fetal rhythm that will be collected
Sound signal is compressed with existing data compression algorithm, and uploads to mobile phone end in real time, and mobile phone terminal decompresses data again,
And compensation data is carried out according to the feature of audio signal, to realize playing, store and play back in real time in mobile phone terminal for fetal heart sound.It is logical
Wireless blue tooth transmission means is crossed to be analyzed and processed the fetal heart rate signal surveyed mobile phone of making a gift to someone, it is (such as intelligent using intelligent terminal
Mobile phone) realize that terminal data is shown.
The utility model has advantages below compared with prior art：By the conventional autocorrelation calculation in controller,
Efficiently solve the anti-interference problem of Detection of Weak Signals in fetal heart rate surveillance instrument；Using Bluetooth technology, the tire that will be collected
Cardiechema signals are compressed with existing data compression algorithm, and upload to mobile phone end in real time, and mobile phone terminal decompresses number again
According to, and compensation data is carried out according to the feature of audio signal, to realize playing, store and return in real time in mobile phone terminal for fetal heart sound
Put；Pregnant woman, which can stay at home, oneself monitors fetus situation, and mobile terminal both can be smart mobile phone or tablet PC
Or portable computer, furthermore it is also possible to obtain expert opinion online by network.
