Description
Technical field
The present invention relates to intelligent diaper, and in particular to a kind of more induction points have the intelligent diaper of diaper saturation prompting function
And its monitoring method.
Background technology
Since conventional diaper is replaced frequent, flushing dose is very big, slightly not note that the skin of baby be easy for being immersed in urine stain and
Just in stain, cleaning and drying condition are bad, easily grow bacterium.Disposable paper diaper are answered generation and are given birth to, and are increasingly subject to youth
Parent's likes.Many times, big people because carelessness or other reasons, can often forget about and change paper diaper to baby, these
Factor can all jeopardize the health of baby.Intelligentized paper diaper have more catered to the demand in market.
Existing intelligence diaper is used places a pair of induction electrode for having certain distance in induction region, is sensed by detecting
Whether the resistance value of electrode determines whether defecation in the range of given threshold, and principle is similar to Raindrop sensor.Induction electrode electricity
Change in resistance means the humidity change of electrode environment, so it is directly to use humidity sensor to have another Humidity Detection mode
Device, defecation has been detected whether with the change of humidity sensor combination temperature.But existing this method is only able to detect whether there is row
Just, feces volume can not be analyzed；And without the resolution capability of stool and urine, if baby bowel movement may detect not
Arrive；Humidity sensor combination temperature approach sensor easily produces wrong report or fails to report.Moreover, induction electrode is arranged on a monoblock base
On bottom, poor air permeability, very big injury is caused to the skin of baby.
The content of the invention
For above problems of the prior art, the present invention proposes a kind of more induction points and is reminded with diaper saturation
The intelligent diaper and its monitoring method of function, using multiple induction regions, carry out accurate judgement, and have size to whetheing there is defecation
Just resolution capability.
An object of the present invention is to provide the intelligent diaper that a kind of more induction points have diaper saturation prompting function.
The intelligent diaper bags that more induction points of the present invention have diaper saturation prompting function include：Substrate, multigroup detecting electrode
And Multiplexing Unit；Wherein, it is distributed multigroup detecting electrode from front to back on the surface of substrate and forms sensing arrangement, each group of detection
Electrode includes two independent induction electrodes；Substrate is discontinuous, and substrate has gap between each induction electrode, forms hollow out
Or list structure；Each induction electrode includes two metal electrodes, and two metal electrodes are separately positioned on up and down the two of substrate
A surface, and two metal electrodes of same induction electrode are mutually conducted；Sensing arrangement is arranged on diaper close to skin
Surface, multigroup detecting electrode are distributed from front to back along diaper central axes, two metal electrodes difference of each induction electrode
It is outwardly directed to skin and inwardly diaper；It is saturating close to the tiling insulation of the surface of infant skin towards diaper in multigroup detecting electrode
Surface layer of water；Each induction electrode is connected to Multiplexing Unit by conducting wire respectively；Multiplexing Unit be arranged on the surface of diaper towards
Baby's belly and the position for not influencing infant activity；The each two induction electrode of Multiplexing Unit selection detecting electrode forms an inspection
Electrode pair is surveyed, each detecting electrode is to being connected to a single channel of Multiplexing Unit；When there is defecation, detecting electrode pair
In a pair of of induction electrode between resistance value change, through wire transmission to Multiplexing Unit；Multiplexing Unit by resistance value and
Situation of change in a period of time, judges whether defecation, and determines whether stool or diaper saturation, and result is transmitted
To external equipment.
Multiplexing Unit includes：Switching circuit, signal processing circuit, A/D converter, processor and telecommunication circuit；Wherein, often
One induction electrode is connected to the switching circuit of Multiplexing Unit by conducting wire respectively；Processor is selected in each group of detecting electrode
Two induction electrodes form a detecting electrode pair, and processor control switching circuit, two induction electrodes in same group are connected
It is connected to an independent channel of the signal processing circuit of Multiplexing Unit；Alternatively, processor selection is per adjacent two groups of detections electricity
In extremely, an induction electrode is respectively taken, forms a detecting electrode pair, processor control switching circuit, by two groups of adjacent detections
Corresponding two induction electrodes are connected to an independent channel of the signal processing circuit of Multiplexing Unit in electrode；When there is defecation
When, the resistance value between two induction electrodes of detecting electrode centering changes, and signal processing circuit by simulation trial using being put
The pretreatment circuit that big device is formed, the input signal for pre-processing circuit are closed with output signal in the function of ratio, logarithm or index
System, pre-processes the output signal transmission of circuit to A/D converter；A/D converter converts analog signals into digital signal, transmission
To processor；Resistance value is obtained by calculation according to the digital signal value of A/D converter in processor, is judged whether according to resistance value
Defecation, and the situation of change according to resistance value within a period of time, determine whether stool or diaper saturation；Processor connects
To telecommunication circuit, result is delivered to external equipment by telecommunication circuit.
The present invention two metal electrodes being mutually conducted of each induction electrode bag, be outwardly directed to respectively skin and inwardly
Towards diaper, defecation is capable of deciding whether and for stool or urine towards the metal electrode of skin, and inwardly diaper
Metal electrode can interpolate that diaper whether saturation.Two mutual conduction modes of metal electrode use two metal electrodes and
Therebetween substrate is got through, and fills conductive material, so that two metal electrodes are mutually conducted；Or using by two
Metal electrode is electrically connected, so that two metal electrodes are mutually conducted.

Resistance value is obtained by calculation in the digital signal value of parallel operation, judges whether defecation and is stool or urine, and according to resistance
Be worth situation of change within a period of time, judge whether be stool or whether diaper saturation；Processor is connected to telecommunication circuit,
Result is delivered to external equipment by telecommunication circuit.
10. monitoring method as claimed in claim 7, it is characterised in that in step 5), processor judges whether defecation, and
Judge whether be stool or whether diaper saturation, specifically include following steps：
A) the resistance value number two induction electrodes that processor continuously records a defecation detecting electrode within a period of time
According to being for a period of time 1s~10min；
B) maximum, minimum value, average value and the root-mean-square value of internal resistance value data this period are found out, as with reference to data；
C) select a time window to judge for defecation, and find out the maximum and minimum of time window internal resistance value data
Value；
D) according to the maximum in time window and minimum value slope calculations, so as to obtain the change rate of resistance value；
E) defecation is judged whether according to the change rate of resistance value, if change rate exceedes defecation threshold value, is judged as defecation, if
Change rate is then judged as non-defecation not less than defecation threshold value；
F) judge whether stool or diaper saturation in the retention time of defecation threshold value according to resistance value, protected if the retention time exceedes
Threshold value is held, then is judged as stool or diaper saturation, is otherwise urine.
