The fetal movement signal automatically detecting identifier further comprises an ARM (Advanced Risc Machines) chip, a time chip, a sound alarming device and a liquid crystal display, wherein the output end of the time chip and the output end of the signal processing circuit are respectively connected with the input end of the ARM chip, and the output end of the ARM chip is respectively connected with the sound alarming device and the liquid crystal display. The fetal movement signal automatic detecting identifier disclosed by the invention can be used for detecting fetal movement signals in real time and judging whether a fetal movement signal is abnormal or not according to the ARM chip, thus realizing the automatic detection identification on the fetal movement signal.
Description
Technical field
The present invention relates to a kind of automatic detection recognition device of Fetal Movement Signal, belong to technical field of medical instruments.
Background technology
Because Fetal Movement Signal belongs to sporadic, there is not rule to follow; Therefore all be to adopt the mode of the own perception counting of anemia of pregnant woman to judge that normally whether fetus all the time.Detect Fetal Movement Signal in the prior art, can only whether check oneself foetus health from the number mode through the anemia of pregnant woman; A lot of anemia of pregnant woman are because neglect from the loaded down with trivial details of number modes, can not in time find or accurately judgement the fetus fetal movement abnormal phenomena of cord around neck, in utero appearances such as poverty-stricken, cause having incured loss through delay the timely treatment to the latter half of gestation fetal abnormality.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly can detect Fetal Movement Signal in real time, and can whether detect the device of identification to Fetal Movement Signal unusually automatically.
The present invention adopts following technical scheme in order to solve the problems of the technologies described above:
A kind of Fetal Movement Signal detects recognition device automatically, comprises touch force sensor, signal processing circuit, and the outfan of said touch force sensor is connected with signal processing circuit, also comprises ARM chip, time chip, voice guard, liquid crystal display screen; Wherein, the outfan of time chip, the outfan of signal processing circuit are connected with the input of ARM chip respectively, and the outfan of ARM chip is connected with voice guard, liquid crystal display screen respectively.
As further optimization of the present invention; Said signal processing circuit comprises Wheatstone bridge change-over circuit, high pass block isolating circuit, signal amplification circuit, low-pass filter circuit and second amplifying circuit; The outfan of said touch force sensor links to each other with the input of Wheatstone bridge change-over circuit; The outfan of Wheatstone bridge change-over circuit links to each other with the input of high pass block isolating circuit; The outfan of high pass block isolating circuit links to each other with the input of signal amplification circuit; The outfan of signal amplification circuit links to each other with the input of low-pass filter circuit, and the outfan of low-pass filter circuit links to each other with the input of two-stage amplifier, and the outfan of two-stage amplifier links to each other with the input of ARM chip.
As further optimization of the present invention, said touch force sensor adopts FSL05N2C type touch force sensor.
