The specific embodiment
As shown in Figure 1, a kind of intelligent doppler baby ' s heart instrument based on Internet of Things described in this utility model embodiment, comprise signal acquisition module, signal condition module, signal processing module and signal output module, described signal acquisition module comprises transmitter module 1, receiver module 2 and demodulation module 3, transmitter module 1 is connected fetal rhythm 13 with receiver module 2, receiver module 2 connects demodulation module 3, described signal condition module comprises signal amplification module 4, filtration module 5 and analog-digital converter 6, signal amplification module 4 connects demodulation module 3 and filtration module 5, described signal processing module comprises microcontroller 7 and power amplifier 8, filtration module 5 is connecting analog transducer 6 and power amplifier 8 respectively, analog converter 6 connects microcontroller 7, described signal output module comprises earphone and speaker 9, display screen 10, bluetooth module 11 and USB12, power amplifier 8 frames connecting with headphones and speaker 9, microcontroller 7 connects respectively display screen 10, bluetooth module 11 and USB12.
During concrete use, signal processing module mainly consists of microcontroller 7 and intelligent algorithm, can completion system controls and the realization of intelligent algorithm; Earphone and speaker 9 can pass through the direct perception of anemia of pregnant woman's audition, display screen 10 can pass through the direct perception of anemia of pregnant woman's vision, bluetooth module 11 and USB12 can transfer data to terminal unit (mobile phone or panel computer) connected to the network, by analysis expert data, offer more comprehensively foetus health information of anemia of pregnant woman.Terminal draws after comprehensive foetus health information, and foetus health directiveness suggestion and early warning can be provided, once note abnormalities, prompting anemia of pregnant woman is done further and is made a definite diagnosis to hospital.
As shown in Figure 2, this utility model has abandoned traditional manual record mode and the simple notation system of single-chip microcomputer calculates Fetal Heart Rate, and adopts intelligent algorithm to obtain real-time Fetal Heart Rate.Whole intelligent algorithm can be divided into that digital filtering, signed magnitude arithmetic(al), dynamic thresholding are chosen, the five steps such as self correlation judges, heart rate calculating.Digital filtering adopts convolution mode that a band filter is set, and filtering noise disturbs; Dynamic thresholding is chosen and is adopted two way classification to obtain an accurate threshold values to carry out the interference that judgement impacts to self correlation of filtering major part; Self correlation judgement and heart rate calculate the mode that adopts Data Segmentation, calculates in real time and obtain Fetal Heart Rate, and final result is exported.
This utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
