Abstract

The utility model discloses an information processor for a baby, which is used for processing the information that the baby cries, lifts a quilt, wets a bed, etc. when sleeps. A sound controlling part of the information processor for a baby adopts a sound recognizing circuit, and can distinguish the baby's crying sound from suddenly produced sound of the outside in order to prevent the misoperation of shaking the bed. Quilt lifting message sending adopts time delay instruction. A message sending circuit works when the temperature of a sleeping nest rises to the normal temperature. A sensing part of the urine moisture sensor adopts a fork structure. Two electrodes are arranged on one conductive plate to form an integral body. The utility model has the advantages of reliable sensing.

Description

Baby's message handler

A kind of baby's message handler that is used in combination with its special-purpose furniture when the utility model relates to children sleeping.

Transmit the product of information when now being used for baby sleep, function is all more single, owing to the reason on structure and the performance, be difficult to be widely used, the acoustic control starter gear of using as some automatic shaking table, because acoustic control part can not be discerned vagitus and extraneous burst of sound, often make the shaking table misoperation and play opposite effect.

The purpose of this utility model is a problem to be solved during at baby sleep, as needs acoustic control to shake when crying, urine wets, lift by the time need timely alarm, a kind of collection with voice recognition capability is multi-functional to be baby's message handler of one and provide.

For achieving the above object, circuit of the present utility model shakes instruction by acoustic control and urine wets, lifts by alarm and combine, and according to its needs, also urine can be wet, lift by two of alarms and combine.Reliable for the guarantee information transmission, the circuit with discrimination function is partly adopted in acoustic control.

Concrete technical scheme of the present utility model is: the pickup part is made up of acoustic pickup MIC, resistance R 2, and preposition amplification is made up of triode D2, D3, resistance R 4, R5, by capacitor C 2 acoustic pickup MIC is connected with preposition amplifier section.Crying during according to baby sleep generally is continuous, and extraneous burst of sound then is of short duration, single situation, and its voice recognition circuit adopts in special time, differentiates with the number of times that receives voice signal.Its time is set and is made up of resistance R 6, capacitor C 3 and 1/2nd dual time base circuit IC1, and single-shot trigger trigger is made up of resistance R 7, C6 and 1/2nd dual time base circuit IC1.Numeration differentiates that imitating IC circuit 2 by note finishes, its power supply by

The MC1 time set partly provides, trigger pip by

The single-shot trigger trigger that IC1 forms provides, and shakes instruction Y and forms the time that monostable output and qualification are shaken by IC3, resistance R 10, capacitor C 8, and IC2 and IC3 pass through the crosslinked and acting in opposition of triode D4.

Its principle of work of voice recognition circuit is: sound is picked up by acoustic pickup MIC, be coupled to the two-tube amplifier that D2, D3 form by C2, signal triggering dual time base circuit IC1 after the amplification, an IC1 part is set the working time for counting circuit IC2, a part is formed single-shot trigger trigger, makes IC2 can trigger numeration reliably.Only in special time, when the accumulative total of sounds trigger reaches its stated number, just there is signal to be transferred to IC3, IC3 will shake instruction Y output on the one hand, and control is shaken the time on the one hand, as once shaking in the time, fail to make child's peace and quiet, circuit will start once more, repeat the work of last time, till child sleeps peacefully.When running into extraneous burst of sound, as thing fall on the ground or when closing the sound of door and window and speech higher individual sound picked up by MIC too, and deliver to IC2 by IC1.Because in the specific time, the accumulative total sound signal does not reach 4 times, IC2 then quits work, and the effect of automatic discriminating has so just been played in refusal output.

The alarm circuit is made up of dual time base circuit IC4, triode D7, D8 etc./ 2nd of a dual time base circuit IC4 is the setting-up time of devoting oneself to work of delaying time, the normal back of the temperature alarm system in the quilt that guarantees just begins to devote oneself to work, it and R14, C9, D8 form the order set of devoting oneself to work of delaying time, when power connection picks up counting, and when reaching setting-up time, 10 pin electronegative potentials transfer noble potential to, and promptly begin to devote oneself to work this moment.RT, D7, RL and

IC4 forms urine and wets, lifts by the alarm disposal system, by lifting the signal that is picked up by temperature sensor RT, amplifies 8 pin of delivering to IC4 through triode D7.The resistance of RT is step-down with the rising of temperature, and when RT is in high temperature (about 32 ℃) in quilt, the electrode of triode D7 is that the 8 pin current potentials of IC4 are higher than

VCC, 9 pin of IC4 are electronegative potential, after quilt was raised, the RT environment temperature descended rapidly, the resistance of RT increases thereupon, when temperature is lower than 26 ℃, triode D7 with the 8 pin current potentials of IC4 be pulled down to less than

VCC, the IC4 upset, 9 pin promptly send the alarm instruction.Urine wet sensor RL 8 pin direct and IC4 link, and along with the variation of RL resistance, also can directly control the variation of the 8 pin current potentials of IC4.When urine was soaked diaper, the resistance of RL two interpolars that paste mutually reduced with it, and 8 pin current potentials decrease, time base circuit IC4 upset, and 9 pin become noble potential and send the alarm instruction.

The utility model will be urinated wet alarm and lift by the alarm binomial and unify, promptly constitute baby's message handler of two functions, its circuit and principle of work and above-described alarm part are in full accord, and its difference is power supply and sound equipment are integrated in one, and are beneficial to convenient the use.Its concrete scheme is formed control circuit by dual time base circuit IC4, triode D1, D2, / 2nd of a dual time base circuit IC4 is that alarm is partly set the time that time-delay is devoted oneself to work, by urine wet sensor RL with lift the information of being extracted by temperature sensor RT, that triggers dual time base circuit IC4 1/2nd sends the alarm instruction in addition, realizes its alarm and trigger sound equipment IC5.

The urine wet sensor RL that the utility model circuit connects, one termination power negative pole, 8 pin of one end and IC4 join, its transducing part adopts fourchette structure, promptly is similar to both hands and refers to intersect alternate, insulated from each other the two poles of the earth printed panel, with two utmost point cloth on a current-carrying plate, the two poles of the earth wiring and socket respectively link and form the wet sensing element of urine, lift thermistor is housed in the temperature sensor RT, and the thermistor two ends link to form by wiring and socket respectively and lift by temperature sensing component.

The utility model compared with prior art has following advantage:

1. the acoustic control of will crying starting has modern design, structure characteristics small and exquisite, easy to use with urinating wet alarm, lifting by alarm three top function combinations, and it can be widely used in various electronic acoustic control shaking tables.Especially acoustic control is shaken, owing to adopt the voice recognition circuit, can differentiate baby's sob and extraneous burst sound, shakes instruction thereby can send exactly.

2. will urinate wet alarm and lift together by two function combinations of alarm, the infant who is fit to very much various occasions sleep uses, especially sleep at night, the adult worries most be child lift by and bed-wetting, had it can remove this puzzlement.
