Description
Technical field
The present invention relates to intelligent diaper, and in particular to a kind of more induction point intelligence diapers and its monitoring method.
Background technology
Because conventional diaper is changed frequent, flushing dose is very big, does not pay attention to slightly, the skin of baby be easy for being immersed in urine stain and
Just in stain, cleaning and drying condition are bad, easy breed bacteria.Disposable paper diaper are answered generation and given birth to, increasingly by youth
Father and mother'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 intelligent diaper uses places a pair of induction electrodes 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 is 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 failed 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 point intelligence diapers and its monitoring
Method, using multiple induction regions, accurate judgement is carried out to whetheing there is defecation, and there is stool and urine resolution capability.
It is an object of the present invention to propose a kind of more induction point intelligence diapers.
More induction point intelligence diaper bags of the present invention include：Substrate, multigroup detecting electrode and Multiplexing Unit；Wherein, in base
The surface at bottom is distributed multigroup detecting electrode and forms sensing arrangement from front to back, and each group of detecting electrode includes two independent sensings
Electrode；Substrate is discontinuous, and substrate has space between each induction electrode, forms hollow out or list structure；Sensing arrangement is set
The surface close to skin in diaper is put, multigroup detecting electrode is uniformly distributed from front to back along diaper axis, or according to need
Want irregular and divide equally cloth；On the surface of the multigroup detecting electrode permeable top layer of tiling insulation；Each induction electrode passes through wire respectively
It is connected to Multiplexing Unit；Multiplexing Unit selection each two induction electrode forms a detecting electrode pair, each detecting electrode pair
It is connected to a single channel of Multiplexing Unit；Multiplexing Unit is arranged on the surface of diaper towards baby's belly and does not influence baby
The position of youngster's activity；When there is defecation, the resistance value between a pair of induction electrodes of same detecting electrode centering changes, warp
Wire transmission is to Multiplexing Unit；Change and retention time of the Multiplexing Unit by resistance value, judge whether defecation and are big
Just still urine, and result is sent to external equipment.
Multiplexing Unit includes：Switching circuit, signal processing circuit, A/D converter, processor and telecommunication circuit；Each
Induction electrode is connected to the switching circuit of Multiplexing Unit by wire respectively；Processor selects two in each group of detecting electrode
Induction electrode forms a detecting electrode pair, processor control switching circuit, two induction electrodes in same group is connected to
One independent channel of the signal processing circuit of Multiplexing Unit；Or during processor selection is per two groups of adjacent detecting electrodes,
An induction electrode is respectively taken, forms a detecting electrode pair, processor control switching circuit, by two groups of adjacent detecting electrodes
Corresponding two induction electrodes are connected to an independent channel of the signal processing circuit of Multiplexing Unit；When there is defecation, one
Resistance value between two induction electrodes of individual detecting electrode centering is changed, and signal processing circuit uses is amplified by simulation trial
The pretreatment circuit that device is formed, the functional relation of the input signal of circuit with output signal in ratio, logarithm or index is pre-processed,
The output signal of pretreatment circuit is transmitted to A/D converter；A/D converter converts analog signals into data signal, transmit to
Processor；Processor according to the digital signal value of A/D converter by the way that resistance value is calculated, so as to obtain humidity, and root
According to situation of change of the humidity within a period of time, judge whether defecation and be stool or urine；Processor is connected to logical
Believe circuit, result is delivered to external equipment by telecommunication circuit.

Internet of Things NB-IoT mode accesses internet.By network, the various relevant informations of guardian remote inquiry baby, baby is understood
The real-time condition of youngster.
The position of Multiplexing Unit does not influence the comfort level of baby as far as possible, on the diaper of face baby's belly, works as urine
Multiplexing Unit is sandwiched among diaper and baby's belly after cloth is worn, and this mounting means is to measure the breathing of baby
The monitoring functions such as frequency, body temperature, blood oxygen saturation and heart rate.
The material on permeable top layer of insulating uses cotton material.
The surface of diaper is located at outside sensing arrangement, or is built in diaper；In the mode of peripheral hardware, the base of sensing arrangement
Bottom is arranged on the surface of diaper fitting skin, and multigroup detecting electrode is outwardly directed to skin and inwardly diaper respectively, multigroup
The surface permeable top layer of laying insulation of induction electrode；In built-in mode, sensing arrangement is set in the guide layer of diaper, it is more
For group induction electrode towards skin, the surface of multigroup induction electrode on guide layer sets permeable top layer of insulating.
The size of substrate hollow out is between 0.1~40mm；Multigroup detecting electrode uses photoetching, crimping, printing or corrosion
Mode prepare in substrate.
Multigroup detecting electrode of the present invention can be directed to the difference of baby men and women, design different arrangement modes.For treasure for Man
The density that treasured is designed as forward position detecting electrode is higher, so can more sensitively monitor a small amount of urinations, middle part
Lower with the density of the detecting electrode of the Position Design at rear portion, in the case where ensureing to fail to report, saving material reduces cost
And design difficulty.As a same reason, it is designed to that the density of the detecting electrode at both ends is low for treasure for woman treasured, and the density in centre position is high.
In addition, the density degree of detecting electrode is directly connected to the lower limit of the urine urine volume of triggering alarm.The electricity of comparatively dense
The problem of can extremely having more preferable sensitivity, but line being brought excessive；Sparse electrode can reduce wiring quantity, but
It is that urine urine volume may be failed to report when very few.Therefore, electrode uses the arrangement mode of non-uniform Distribution, can reach use
There is higher defecation detection sensitivity again while less wiring quantity.
