Description

Baby-monitoring device and method thereof
Technical field
The present invention relates to a kind of monitoring device, particularly a kind of baby-monitoring device and method thereof.
Background technology
Along with the influence that science and technology is maked rapid progress and quality of life improves, utilization rate or efficient for things on each field, bet greatest thought and mental and physical efforts invariably, the mechanism of picture tool caution character, in medical treatment at present or nurse all is main demand, because by its design, can control or take precautions against the unexpected situation of patient easily and take place.
At present because behind the industrialization development of society's height, the nuclear family of double salary becomes the main flow in the society, for the nuclear family that just has the neonate to be born, father and mother are in the especially loaded down with trivial details and fatigue of baby-sit after work, often want the neutral gear when baby sleep, the thing of the processing of snatching a moment's leisure from a busy schedule some oneself, be afraid of again not the baby at one's side the time, the baby wakes up and crys and can't learn and be looked after; Or oneself is busy with forgetting the time that the baby should take food and taking medicine the time.
Therefore, how to provide a kind of baby-monitoring device and method thereof with caution mechanism, (for example, father and mother or blankets, cloth for baby nurse) treatment work becomes one of researchist's problem to be solved with auxiliary caregiver.
Summary of the invention
In view of above problem, the invention provides a kind of baby-monitoring device and method thereof, by the present physiological status of sensing baby, and when the baby cries and screams, needs feed or takes medicine, remind the caregiver with the caution effect, so, can allow the caregiver utilize the time to have a rest more efficiently or handle other work, and when the baby need look after, go to the treatment that gives real-time.
Therefore, the disclosed baby-monitoring device of the present invention includes: sound transducer, in order to the voice signal in the present environment of sensing; The audio frequency internal memory stores the voice signal of corresponding baby when crying and screaming; Whether the audio frequency comparator circuit conforms to the voice signal of baby when crying and screaming in order to the comparison voice signal that sound transducer sensed, and when conforming to, exports an alarm signal; Controller is in order to receive alarm signal, to produce control signal; And the caution unit, in order to receive control signal, remind the caregiver to confirm baby's current state to send the caution effect.
In addition, the present invention discloses a kind of baby-monitoring method, many group sensing modules is set around a baby, with this baby of sensing present physiological status, position, its baby-monitoring method includes the following step: according to the state value of sensing module, judge whether that event occurs; When the state value of sensing module changes, confirm that then event occurs, and start sound module; Judge whether to be single incident; When confirming as single incident, then control sound module and play the preset warning audio with default volume; When confirming as most incident, then control sound module and play the caution audio of each incident correspondence to strengthen volume.
By this baby-monitoring device and method thereof, away from keyboard in the time of can allowing the caregiver feel at ease to utilize baby sleep to the elsewhere, handle some matters in home or individual private business or take a quick nap, and then relax the long-term caregiver's of baby-sit psychological pressure for a long time, and reach best practical function and economic worth.In addition, the present invention detects by the surrounding air of gas anomaly sensing cell to the baby, takes place so that effective strick precaution is unexpected.

Embodiment
Please refer to Fig. 1, be the system calcspar of first embodiment of the invention.As shown in Figure 1, baby-monitoring device 100 of the present invention includes sound transducer 10, filtering circuit 11, audio frequency internal memory 12, audio frequency comparator circuit 13, time setting unit 20, the unusual sensing cell 30 of air, scope of activities limiting unit 40, mosquito repellent unit 50, control panel 60, controller 70, wired caution unit 80, wireless launcher 90 and wireless caution unit 91.
Sound transducer 10 is in order to the voice signal in the present environment of sensing.Sound transducer 10 is preferable be arranged at the baby near.Sound transducer 10 can for example be a microphone.
Filtering circuit 11 is connected with sound transducer 10.Filtering circuit 11 carries out filtering in order to the voice signal that sound transducer 10 is received.Filtering circuit 11 can for example be low-pass filter or Hi-pass filter.
Audio frequency internal memory 12 stores the voice signal of corresponding baby when crying and screaming.Its sound intermediate frequency internal memory 12 can be connected with filtering circuit 11.So, the caregiver can record the voice signal that the baby sends under various states, and is stored in the audio frequency internal memory 12.
Audio frequency comparator circuit 13 is connected with filtering circuit 11, audio frequency internal memory 12.Audio frequency comparator circuit 13 can for example be to carry out speech recognition by a direct acoustic ratio to mode or in an acoustic model comparison mode.Acoustic model comparison mode can be passed through a concealed markov model (Hidden Markov Model, HMM), (Dynamic Time Warping DTW) carries out the voice signal identification with voice masterplate comparison (Template Matching) arbitrary acoustic model wherein for a neural network (Neural Networks), dynamic time calibration.
Time setting unit 20 is connected with controller 70.Time setting unit 20 is in order to setting and the setting-up time that stores more than a group, and when the present time arrived setting-up time, the output alarm signal was to controller 70.Time setting unit 20 can for example be a timer.So, the caregiver can take medicine time or the like by time, baby bathing time or the baby that time setting unit 20 is set the feeding baby.
The unusual sensing cell 30 of air is connected with controller 70.The unusual sensing cell 30 of air is in order to the air in the present environment of sensing, and when containing abnormal gas in air, the output alarm signal is to controller 70.The unusual sensing cell 30 of air is main at carbon monoxide (CO).The unusual sensing cell 30 of air can utilize tin oxide (SnO2) Metal Oxide Semiconductor Gas Sensing material, prepare the SnO2 nano particle by refinement of particle ultra micro and doping process, and as matrix certain catalyzer that mixes, carry out finishing through suitable sintering process, make heater-type slug type carbon monoxide sensing assembly, can survey the CO gas of 0.005%～0.5% scope, semiconductor air-sensitive assembly has the branch of N type and P type.N type resistance when detecting reduces with the increase of gas concentration; P type resistance increases with the increase of gas concentration.SnO2 Metal Oxide Semiconductor Gas Sensing material belongs to N-type semiconductor, and the oxygen in 200～300 ℃ of its absorbed airs of temperature forms the negative ion absorption of oxygen, the electron density in the semiconductor is reduced, thereby its resistance value is increased.When running into when the inflammable gas (as carbon monoxide etc.) that can supply with electronics is arranged, original Xi Fu oxygen desorption, and be adsorbed on the metal-oxide semiconductor (MOS) surface with the positive ion state by inflammable gas; Oxygen desorption ejected electron, inflammable gas is also wanted ejected electron with the absorption of positive ion state, thereby oxide semiconductor conduction band electron density is increased, and resistance value descends.Inflammable gas has not existed, and metal-oxide semiconductor (MOS) can recover the negative ion absorption of oxygen again automatically, makes resistance value be elevated to original state.Learn by impedance variation whether carbon monoxide is excessive.
