Description

Wireless induction type diaper and its monitoring device
Technical field
The utility model relates to a kind of diapers, are especially configured with a kind of wireless sense of frequency-shift type wireless radio frequency identification mark Formula diaper and its monitoring device are answered, monitored device can be read after diaper absorbent urine or moisture, and then set by monitoring Preparation put up a notice information indicate diaper it is wet.
Background technique
The diaper of system only has the function of absorbing urine or moisture, without the function that proactive notification diaper is wet.In addition There are also a kind of known diapers can be after absorbing urine or moisture reminding by way of changing the appearance color of diaper Other people's diaper is wet;In the TaiWan, China invention patent certificate CN103845156 for having checked and approved bulletin, a kind of tool sensing is proposed The paper diaper of function can be used with unification wireless radio frequency reader, and the paper diaper for having sensing function include:One absorption pad, a sense Survey line group and a radio RF identification label.Absorption pad, which has, is located at two waist sides of two opposite lateral sides, and including:One The absorbed layer that liner layer, a waterproof layer, one are folded in liner layer Yu waterproof interlayer, one be folded in liner layer and waterproof interlayer from Type paper.Release paper is extended inside by a side of absorption pad, so that absorption pad is formed one and is opened on the side accommodating space.Sense wire Group contains at least two sense wires, is set to liner layer and waterproof interlayer, and each sense wire is distinguished at least partially by absorbed layer and both ends Extend towards waist side, and wherein one end is located in accommodating space;And a radio RF identification label, accommodating can be set to extracting out Space, and be electrically connected with sense wire;The absorbed layer of absorption pad absorb excreta and it is moist when, keep two sense wires mutually electrical Be connected and be collectively formed circuit with radio RF identification label, wireless radio frequency reader reading radio RF identification label and The resistance change between two sense wires is detected, and issues a notification signal.The paper diaper of this tool sensing function use can With removable wireless radio frequency identification label, although the system connecting with Conditional electronic sensor is compared, can limitedly reduce The production cost production cost of current radio RF identification label (because constantly decline), but this frequent extracting replacing is set Meter is easy to the radio RF identification label of damaging delicate, and using upper very inconvenient.
In addition in the TaiWan, China invention patent certificate I533857 for having checked and approved bulletin, a kind of tool wireless sensing is proposed The diaper structure and its diaper detecting system of drenched state, including a diaper ontology, an at least communication chip, at least a metal day Line and a signal reader, wherein the communication chip and metal antenna are the outsides for being attached to the diaper application of anti-leakage layers, and phase each other It connects, to form a radio frequency label (Tag), when the diaper ontology is drenched state, leads to diaper application of anti-leakage layers itself The electromagnetism that the change of dielectric coefficient can be such that the impedance value of the metal antenna changes correspondingly, and then the radio frequency label is enabled to be transmitted The wavelength shift of wave signal, but the signal reader can emit the radio frequency label detecting electromagnetic wave, the less radio-frequency Label can transmit a response electromagnetic wave after receiving the detecting electromagnetic wave, so that the signal reader is according to the response electromagnetic wave Wavelength, judges whether the diaper ontology drenches.
Aforementioned known techniques CN103845156 is to be preset with an induction line in diaper inside to connect a radio frequency identification Label, wherein radio RF identification label adopts movable design, is just loaded into the scheduled position of diaper and and induction when in use Route is electrically connected, and causes that sense line is enabled to form short-circuit loop, wireless radio frequency reader after diaper absorbent urine or moisture The resistance change between sense wire is detected to read radio RF identification label, and issues a notification signal.It is above-mentioned another A kind of known technology I533857 is using diaper ontology when being drenched state, because of the change of the dielectric coefficient of the diaper waterproof layer The wavelength for the electromagnetic wave signal that the impedance value of the metal antenna can be made to change correspondingly, and then the radio frequency label is enabled to be transmitted changes Become, although this technological means is different from known technology CN103845156, the current civil less radio-frequency label used Wave frequency belongs to ultra-high frequency band more, and high-frequency wave wavelength is smaller, it is not easy to pass through hydrone, therefore hydrone absorbs this frequency When the electromagnetic wave of section can make the normal ultrahigh-frequency tag of script be attached in aqueous background material, label antenna and water form one Big absorber, therefore antenna can not effectively receive electromagnetic wave, transmission range can become very short at this time.So aforementioned known skill Art I533857 is to inhale when drenching state because of the change of diaper waterproof layer dielectric coefficient itself and in water using diaper ontology Under the influence of receiving hyper band electromagnetic wave, the reading distance of the metal antenna can be made to shorten from length, when being drenched using diaper, nothing The distance of line RF tag allows reader to sound an alarm by the long variation to shorten.As previously mentioned, being saturated with water in diaper, water can be inhaled Electromagnetic wave is received, however narrating distance at this time can be reduced, this makes signal that can disappear, therefore can not judge whether in due to being filled water Disconnected or other factors cause, in addition, such design, reader can read the signal of less radio-frequency label at the beginning; Because making reader that can do the running for receiving signal processing always, this has reader chip and quickly overheats and influence reading performance Problem.
Utility model content
