The specific embodiment
See also shown in Figure 1ly, the fetus education fetus-voice meter of this utility model fetal heart sound, heartbeat waveform and the playback of heart rate value stores synchronized mainly comprises ultrasonic probe, single-chip microcomputer and SD card.Wherein, the ultrasonic probe output signal is divided into three the tunnel, the first via directly is connected with the Chip Microcomputer A passage, fetal heart sound sampling when storing, connect power amplifier behind the second tunnel connection amplifier, Third Road is divided into two-way after connecting amplifying circuit, and one the tunnel directly is connected with another AD passage of single-chip microcomputer, carry out the sampling of signal amplitude, another road is connected with single-chip microcomputer by comparator; The SD card is connected with single-chip microcomputer.
Preferable, on the path of ultrasonic probe connection power amplifier, analog switch is set.Single-chip microcomputer also can be connected with audio frequency (decoding) chip, display screen and button, is connected with analog switch with the DA change-over circuit simultaneously, is connected with host computer by USB interface, and audio chip is connected with power amplifier.
During use, the fetus education fetus-voice meter of this utility model fetal heart sound, heartbeat waveform and the playback of heart rate value stores synchronized can roughly be divided into storaging working mode, playback mode of operation and fetus education mode of operation.
Under the memory module, gather fetal heart rate signal by ultrasonic probe earlier, and the signal that obtains is divided into three the tunnel: first via signal directly is connected with the AD passage of single-chip microcomputer, and fetal heart sound signal is sampled; The second road signal is directly exported fetal heart sound through amplifying circuit, power amplifier and speaker; The Third Road signal is further divided into two-way after amplifying, the one road delivers to the Chip Microcomputer A sampling, and fetal rhythm analogue signal amplitude is converted to digital signal, and draws heartbeat waveform and rod figure, and heart rate value is caught and calculated to another road signal by single-chip microcomputer after the comparator shaping.Afterwards, hear sounds digital signal, heartbeat waveform and heart rate value are packaged as the fetal heart sound file storage on the SD card, realize stores synchronized.Also can on display screen, show heartbeat waveform, rod figure and heart rate value simultaneously in real time, also can host computers such as single-chip microcomputer and PC, MP4 be established a communications link by USB interface, the fetal heart sound file is sent to host computer by serial ports, utilize software to depict fetal rhythm rate trendgram.
When starting playback mode, read the fetal heart sound file of preserving in the SD card earlier, unpacking back extraction heart rate value is shown on the color screen, extract the heartbeat waveform data, be presented on the color screen according to draw heartbeat waveform and excellent figure of Wave data, extract hear sounds digital information simultaneously and after DA handles, emit, reach the synchronous broadcast of hear sounds and heart rate, waveform.
Analog switch is used to control the selection of voice-frequency channel: when fetus-voice meter was in normal test or memory module, analog switch was selected the sound of this path of ANOLOG_SOUND_IN, the most primary simulated sound that probe collection is just come; If playback mode is just selected this path of DA_SOUND_IN, the acoustical signal after the DA conversion just, at this moment, the passage between fetal rhythm probe and the power amplifier is closed.
When selecting the fetus education pattern, single-chip microcomputer reads and is stored in fetal music in the SD card, is sent to after audio frequency (decoding) chip decodes, by power amplifier, loudspeaker plays.
Please cooperate and consult shown in Figure 2ly, SD card of the present utility model links to each other with the SPI1 interface of single-chip microcomputer, and audio chip links to each other with the SPI2 interface of single-chip microcomputer.
Please cooperate and consult Fig. 3, shown in Figure 4, the data packet format of this utility model hear sounds digital signal, heartbeat waveform and heart rate value storage is: preceding 500 of each sector are the fetal heart sound data, the 501st storage heart rate value, 11 the stored waveform data in back, such data format have guaranteed the immediate synchronous of heart sound data and Wave data.During work, at first enter the proper testing pattern, can pass through button operation, enter storage, playback or fetus education pattern: the file of creating a corresponding medical record number when entering storage (recording) pattern, data with the AD sampling during each intervalometer interrupts are deposited in the written document buffer memory, whenever write enough 512 bytes, just in the file of creating, write a sectors of data; Read corresponding medical record number file during playback, read a sector of file, extraction data in the intervalometer interruption is emitted fetal heart sound DA respectively, and heart rate value and waveform show on screen, read next sector after the hear sounds of a sector finishes.
This utility model adopts the SD card as storage medium, single-chip microcomputer (STM32) is as the system core, compatibility is strong, memory space is big, can realize fetal heart sound, heartbeat waveform, the storage of fetal rhythm rate data synchronization and playback, listen fetal heart sound in the time of playback on one side, can on color screen, see the rod figure of fetal rhythm rate and indication heart beating power on one side, more directly perceived, reduced situation when recording more really, also can cooperate upper computer software to describe heart rate trendgram and preservation or printout, thereby be suitable for practicality more.
The above; it only is preferred embodiment of the present utility model; be not that this utility model is done any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in the protection domain of the present utility model.
