Description

Childcare monitoring alarm device {WATCHING AND ALARMING DEVICE FOR NURSING INFANTS}

The present invention relates to a monitoring alarm device for child care, and more particularly, to a device for alerting the guardian in a somewhat distant position to know that the infant is awake and sleeping.

Conventionally, in the case where a parent and a child sleep in a separate room, a sound receiving device including a microphone is placed in a room where the baby is sleeping, and a sound generating device including a speaker is placed in a room where the parent sleeps. A monitoring apparatus is known that continuously monitors the sleeping state as a sound and allows the parents to always hear the sound detected at this time. By such a device, even if a parent sleeps in a separate room, the baby can hear the baby's crying through a speaker installed in the parent's room, so that the baby can be confirmed that the waking up.

However, since the above-described apparatus using a wired line is fixedly installed, there is a disadvantage that it is difficult to widen the application range. In other words, the fixed installation is not a problem at night, but in the daytime, the guardian has to put the child to sleep around and work around the house, so in order to be able to monitor the baby's sleeping condition anywhere, the reception of speakers, etc. The device must be installed. Therefore, if this problem is not solved, the scope of activity of the guardian is difficult to move out of the fixed position.

After all, a guardian who has to take care of a child in the past cannot comfortably leave the child's side and do other things because she does not know when to wake up and find the guardian even while the child is sleeping. So, inevitably, when you have to go a little far away, it was very inconvenient because you had to ask someone to take care of your child, or have to hold or lift your child to sleep.

The present invention is designed to solve such a conventional inconvenience, it provides a means for confirming the fact that the baby wakes up and wakes up, and to notify the guardian who is a little further away by wireless or the like. Let it be technical problem.

According to the present invention, by providing a monitoring alarm device for child care having the above-described function, the guardian can do his work anywhere from a little far from the baby in the house even when the child is sleeping, and also not too far Even if you can come back easily, for example, your neighbor's house or a nearby store, you can go with peace of mind.

A: detection and transmission unit B: reception and alarm unit

C: recording and reproducing unit D: public telecommunication network

1: external sound receiving means 9, 15: speaker

16: alarm light 21: communication terminal

The childcare monitoring alarm device of the present invention provided as a means for solving the above-described technical problem, the detection and transmission means for detecting the sound uttered from the infant and transmitting the alarm signal on the basis, and receives the alarm signal accordingly It is configured as a basic component to receive and alert means to issue an alarm that the guardian can confirm.

More specifically, according to the monitoring alarm device for childcare of the present invention, the detecting and transmitting means is an external sound receiving means for receiving the external sound and converting it into an electrical signal, and the volume of the received sound based on the electrical signal A volume calculating means for calculating and outputting the volume signal as a volume signal, and comparing the output volume signal with at least one reference value to determine where the volume signal belongs to the area divided by the at least one reference value, and corresponding to the corresponding area. Comprising means for outputting at least one drive signal to be output, and at least one drive signal generated from the comparison means for transmitting at least one alarm signal corresponding to each is configured to include,

The receiving and alarming means includes signal receiving means for receiving alarm signals from the detecting and transmitting means and outputting at least one alarm driving signal, alarming means for displaying at least one or more kinds of alarms to the outside, and the signal receiving means. And alarm drive control means for driving the alarm means in accordance with an alarm drive signal from the device.

Preferably, the detecting and transmitting means includes sound recording means for recording music, voice, and the like, which can be prepared in advance or recorded by a guardian, and sound recorded to and reproduced by the sound recording means to the outside. And sound recording means and recording / reproducing control means for controlling the sound generating means to generate sound in accordance with the drive signal generated from the comparing means.

As a result, it is possible to allow the reception and alarm means to generate an alarm and to reproduce the specific sound to the outside by the drive signal which is the output signal of the comparison means. At this time, the specific sound may be a recorded voice of the guardian, an effect sound such as the animal's favorite animal cry, a favorite song, and so on, so that the child who has woken up can be saved until the guardian returns. Therefore, a baby who has woken up can help them not to hurt their emotions by letting them know that someone close to them is interested in them.

In particular, when the childcare monitoring alarm system of the present invention is configured in combination with the existing audio device, such as when the child is sleeping to play music suitable for bedtime, when the baby is awakened or detected or confirmed that the waking of the child The music may be changed to music suitable for emotion, or the prepared voice may be played back.

More preferably, the signal transmission and reception between the detection and transmission means and the reception and warning means of the childcare monitoring alarm device may be a dedicated wireless communication, but may be configured to use a public wired or wireless communication network. In particular, in the latter case, the detecting and transmitting means must further include a connection call control means for connecting to a public communication network, wherein the receiving and warning means must be a communication terminal capable of at least receiving a connection to a public telephone access network. do. In addition, although the reception and alarm means is more preferable if the wireless communication terminal, it is not necessarily limited to the wireless communication terminal.

In addition, when configured to transmit and receive an alarm signal using a public communication network, the detecting and transmitting means may freely change and set a unique connection call number (telephone number) of a communication terminal to be used as a receiving and alarming means at the time of an alarm. It is more preferable to construct. As a result, the user may use the existing wireless communication terminal as a receiving and alarming means, but a wired communication terminal having a unique call number connected by wire to the public communication network may be used as the receiving and alarming means. Therefore, the detection and transmission means are installed in the child's room, the child wakes up, and the alarm signal is sent to the wired communication terminal of the sleeping room where the parents are sleeping, or to the wired communication terminal of the neighbor's house where the parents are sleeping and the alarm sounds Can be set to change.

Further, when the detecting and sending means and the receiving and warning means are connected through a public communication network, the detecting and sending means includes a storage means for storing a message including a text to be transmitted to a communication terminal to be used as the receiving and alerting means at the time of an alarm. In addition, it is preferable that the access call control means transmits a message including the text to a communication terminal set through a public communication network.

By providing the monitoring alarm device for child care of the above-described configuration, it is excellent in the effect that can confirm the fact that the baby waking up in a relatively distant place when the baby is sleeping. In addition, since a conventional wired or wireless communication network can be used, the object can be achieved with a relatively simple configuration.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of the present invention.

1 is a block diagram showing the overall configuration of the monitoring alarm device for child care according to the first embodiment of the present invention.

1 may be logically or physically divided into three parts A, B, and C separated by dotted lines. The first part is the detection and sending unit A, the second part is the receiving and alarm unit B, and the third part is the recording and reproducing unit C.

The detecting and transmitting unit A comprises an external sound receiving means 1, a volume calculating means 2, a comparing means 3, a reference value setting means 4, a transmitting means 5, an antenna 6 and the like.

External sound receiving means (1) includes a microphone, and receives the sound from the outside to generate an acoustic signal which is an electrical signal having an amplitude and frequency corresponding to the amplitude and frequency of the received sound, the volume calculating means (2) Changes the volume of the external sound received on the basis of the electric signal from the external sound receiving means 1 into a format necessary for calculation. Between the external sound receiving means 1 and the volume calculating means 2, a filter circuit for removing noise or an amplifier for amplifying an acoustic signal may be provided, depending on design needs.

The comparison means 3 compares a signal representing the volume from the volume calculation means 2 with a reference value set by the reference value setting means 4, and the drive signal when the volume of the sound received from the outside exceeds the reference value as a result of the comparison. Outputs

The comparison means 3 may be composed of an analog circuit or a digital circuit. If it is composed of an analog circuit, an example composed of a comparator using an OP amplifier, etc. can be presented, and if it is composed of a digital circuit operating based on digital calculation, the volume calculating means 2 is applied to the received sound. It is preferably configured to output the corresponding volume in digital form.

In particular, in the case of the former analog circuit, the comparison means does not require that the name be a comparison circuit, and it is sufficient if the configuration includes a substantial comparison function. That is, if the signal from the volume calculating means is a predetermined value or more, the configuration is sufficient to output the signal. In the simplest case, the multi-stage may be configured by using at least one zener diode or the like which allows a current to flow only when a predetermined voltage or more is applied. In this case, it is given at the time of design without the reference value setting means, and at least there is no formal comparison circuit, but it is possible to perform a substantial comparison.

In addition, it is needless to say that in the case of implementing the latter digital circuit, an auxiliary equipment for digital control, such as an A / D converter for converting an analog signal from the volume calculating means 2 into a digital signal, must be included.

In addition, the reference value set by the reference value setting means 4 may be configured to be not a single number but a plurality of reference values so that the volume of the received sound can be divided into a plurality of sections for identification. In this case, the comparing means 3 is configured to have two or more output stages (when composed of an analog circuit) or to output two or more digitally coded output signals (when composed of digital). Thus, it is determined where the volume of the received sound corresponds to a section divided by a plurality of comparison values, and outputs a drive signal to a predetermined output of the plurality of outputs or outputs an output signal of a predetermined digital code.

In addition, it may be considered to generate another kind of signal when a sound having a predetermined volume or more is received for a predetermined period or more. In the case of adopting such a design, a timer may be provided in addition to the comparison circuit to measure a period during which a sound higher than the reference volume is received, or a delay circuit and a switching means may be provided to keep the sound higher than the reference volume after the reference time. It is contemplated to configure to output the signal of.

As such, the purpose of subdividing and controlling the received sound is to identify the sleeping state or the waking degree of the sleeping baby and to display different alarms according to the degree. More details will be described later. However, it is intended that this function is not an essential configuration that the present invention should have. In other words, the object of the present invention may be realized by setting only one reference value and configuring it to have a simple function of detecting only the volume of the received sound exceeding this reference value and generating a drive signal.

The transmission means 5 comprises drive switching means for transmitting transmission in accordance with the drive signal from the comparison means 3, an oscillator for generating a carrier wave, a signal generator for generating an alarm signal to be loaded on the carrier wave, and an alarm for the carrier wave. It is configured to include at least one modulator for superimposing the signals, and when the drive signal is sent from the comparison means 3, the transmission drive is started, and the alarm signal is loaded on the carrier to be transmitted through the antenna 6.

When the comparing means 3 is designed to transmit a plurality of distinct signals in correspondence with the detected volume, an alarm signal to be carried on the carrier is also set to a plurality of types.

In addition, it is preferable to use normal wireless communication for the communication between the detection and transmission unit A and the reception and alarm unit B. In this case, various methods can be selected for the dedicated direct wireless communication method between the two parts, and the method is not limited thereto. However, the above-described alarm signal may be transmitted and received. Examples of communication modulation methods include frequency-shifting keying (FSK), amplitude-shifting keying (ASK), and pulse-shifting keying (PSK) amplitude phase keying (PSK), which are frequently used for digital communication. Various conventional methods can be considered.

The receiving and warning unit B, which is the second component of the present invention, is configured to include the receiving unit 12, the alarm driving unit 13, and the alarming devices 15, 16, and receives the radio wave transmitted from the detecting and transmitting unit A. In response to this, a plurality of kinds of alarm signals are extracted and alarms corresponding to the respective alarm signals are generated through the alarm devices 15 and 16.

The receiving means 12 is configured to include at least a demodulation circuit for separating the alarm signal from the carrier, the alarm drive control means 13 is demodulated to distinguish the alarm signal extracted from the carrier to the alarm means (15, 16) It is designed to emit a plurality of kinds of alarms in response to each of these alarm signals.

The configuration of the alarm means may be an example of using at least one of generating an alarm sound through the speaker 15 or lighting of the alarm light 16, and the method of displaying the alarm depending on the degree of waking of the baby. It is conceivable to take a manner of generating an intermittent sound through the speaker 15 and flashing the alarm light 16. The alarm drive control means 13 has a different design depending on how the alarm method is selected.

As an example of alarm display method, the sound of baby cry is divided into three according to its volume.When the volume is the smallest, a small frequency of intermittent sound is generated and a small frequency alarm light blinks. For example, an alarm lamp flashes with the occurrence of an intermittent sound of a higher frequency, and when the volume is very loud and lasts for a predetermined time, an alarm may be designed to generate an alarm through the occurrence of an intermittent sound of a higher frequency and an alarm lamp.

In addition, a method of changing the type of alarm sound may be considered, and a method of lighting a plurality of alarm lamps 16 sequentially and gradually from a baby's sleep state to a fully awake state may be used.

On the other hand, when the display is to be distinguished in consideration of the duration of baby crying, the period in which signal reception is continued is measured directly or indirectly, including a delay circuit, a timer, a counter, and the like, and distinguished according to the result. A configuration for alarming should be added to either the detecting and transmitting section A or the alarm driving control means 13 of the receiving and alerting section B.

The recording and reproducing unit C is a component that functions to appease the baby until the guardian returns when the baby wakes up, and includes the audio recording means 8, the sound generating means 9, and the recording / playback control means 7. And record / playback manipulation means 10.

The sound recording means 8 is a recording medium capable of converting sound into an electrical signal and recording the sound. The sound recording means 8 may include a semiconductor recording device using a ROM or a RAM, a magnetic tape recording device, an optical recording device, and the like. You can record the sounds of animals prepared in advance, music that your baby will like, and nurtured by your guardian.

The recording / playback adjustment means 10 is a kind of operation panel that allows the user to directly control recording, predetermined playback content selection, volume adjustment, and the like, and is essential when selecting a method of reproducing sound determined by the manufacturer. It is not.

The recording / reproducing control means 7 controls recording and reproducing according to the adjustment of the adjusting means 10, and when the above-described driving signal is received from the comparing means 3, the recording / reproducing control means 7 is recorded in the recording means 8 in a set manner. The speaker 9 is driven to reproduce the contents.

In addition, a variety of functions, such as a variety of sounds and music alternately generated, or when the baby is sleeping, play music such as lullabies, when waking up to play the recording of the guardian with other music, etc. May be considered.

On the other hand, the recording and reproducing unit C may consider a method of designing using an existing audio system, and conversely, add the function of the parenting monitoring alarm system of the present invention to the existing audio system.

FIG. 2 illustrates a second embodiment of the present invention, which is different from the first embodiment in that the guardian can be notified of the waking of the baby using the existing public communication network D.

The connection call control means 17 corresponds to a means for making a telephone call in a conventional telephone, and is operated when a drive signal is generated from the comparison means 3, and is operated by the telephone number set in the storage means 18. To call the communication terminal 21.

The storage device 18 records and stores one or more calling telephone numbers and call texts for text transmission.

The call number change setting means 19 functions to change and set the call number according to the needs of the guardian, so that at least one call number can be recorded in the storage device 18, or the recorded content can be changed and set.

On the other hand, as an example of the method of the call connection means is connected to the public communication network D to send an alarm signal to the communication terminal 21 by attempting a direct telephone connection to the communication terminal 21 to generate a ring tone to the terminal after the telephone It may be considered to repeat the process of hanging up, reconnecting to generate a ring tone and hanging up. In this case, there is an advantage that can reduce the burden of special communication charges.

In addition, a method of using a text transmission service may be considered. That is, when the guardian's communication terminal 21 is in a call, a problem may occur in which a ringing tone may not be generated, so that the sentence 21 is displayed on the terminal 21 having the guardian using a text transmission service. Can be.

When a character is displayed on the communication terminal 21 of the guardian using a text transmission service, the character to be displayed on the terminal may be a method determined by the manufacturer, and the user may directly edit or select one of a plurality of characters. However, if the baby's sleep state is to be classified and displayed, at least two or more transmission strings should be stored in the storage device 18.

On the other hand, as a method for connecting to the public communication network 20 may use a conventional wired telephone terminal or a wireless communication terminal, it may be installed in the childcare monitoring alarm apparatus of the present invention in these wired and wireless communication terminals. In addition, it may be considered to transmit a text message through an Internet connection through a personal computer.

Although the communication terminal 21 preferably uses a wireless communication terminal, the communication terminal 21 is not limited thereto, and a public wired communication terminal may be used. At this time, the wired communication terminal may be a wireless telephone in the home, a neighbor's telephone, and the like.

That is, the communication terminal 21 serving as the receiving and alarming means C is one of various kinds of devices such as a wired telephone, a wireless pager, a portable telephone, and the like depending on which communication terminal the telephone number set by the call number change setting means 19 is. Which can be
