Description

Baby walker danger alarm system {Alarm system of danger for baby-walker}

The present invention relates to a baby walker hazard warning system, and more particularly, a baby walker equipped with an optical transmitter; An optical receiver installed at a dangerous object or a dangerous place inside a house and equipped with a receiving module for receiving the light emitted from the optical transmitter and a measuring module for measuring the sensitivity of the light received from the receiving module and comparing it with a predetermined reference value. ; And a warning module for transmitting and receiving data through wireless communication with the optical receiver.

In the case of infants who do not recognize dangerous objects, the guardian has the trouble of constantly monitoring the infant's access to dangerous objects, and accidents that occur while children are approaching dangerous objects are generally caused when the guardian's monitoring is temporarily interrupted. Will occur. However, in reality, it is impossible for a guardian to always monitor an infant, so that an infant is frequently exposed to danger.

In particular, infants who walk on foot while learning to walk, start moving around by the walker inside the house, and infants who are not good at judgment do not realize that objects such as stoves, electric heaters, and rice cookers are dangerous. Therefore, when the guardian stops monitoring for a while, there is a problem in which the infant walks on the dangerous object and is exposed to the risk of an accident.

On the other hand, the movement detection device used in automobiles, etc., uses an ultrasonic sensor to predict the distance by determining the intensity of the ultrasonic signal emitted from the ultrasonic sensor reflected from the stationary object, and the object approaches the ultrasonic sensor within a predetermined distance. Alarm occurs.

When the signal transmitted from the ultrasonic sensor is reflected from a fixed object and received by the ultrasonic sensor, the movement detecting device compares a received signal of a voltage level corresponding to the intensity of the received ultrasonic signal with a predetermined reference value and alerts the user if the reference value is higher than the reference value. It follows the principle of generating sound and detects all objects in the area that can reflect ultrasonic signals.

However, when the technology related to the movement detecting device is applied to a walker, whether the approaching object is a dangerous object can not be distinguished, and thus selective detection of the dangerous object is impossible and an alarm is unconditionally generated when a predetermined distance is reached. A problem occurs.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above and the technical problems that have been requested from the past.

Specifically, it is an object of the present invention to provide an infant walker hazard warning system that can prevent the risk caused by the infant walking walker approaching a dangerous object or dangerous place.

In addition, an object of the present invention is to provide a pedestrian danger warning system for infants to detect the dangerous object selectively walked by the pedestrian walking, and notify the guardian when the walker approaches the dangerous object.

Infant walker danger warning system according to the present invention for achieving this object,

Infant walker equipped with an optical transmitter;

An optical receiver installed at a dangerous object or a dangerous place inside a house and equipped with a receiving module for receiving the light emitted from the optical transmitter and a measuring module for measuring the sensitivity of the light received from the receiving module and comparing it with a predetermined reference value. ; And

An alarm module for transmitting and receiving data through wireless communication with the optical receiver and generating an alarm message;

It consists of a structure comprising a.

That is, the infant walker danger warning system according to the present invention is a system for informing the guardian by generating an alarm message when a walker walks near a dangerous object or a dangerous place. There is an effect that can prevent in advance the risks that occur when accessing.

In addition, due to the structure of the optical receiver for receiving the light emitted from the optical transmitter in the dangerous object, the alarm sounds only when the pedestrian approaches the dangerous object, unlike the technology of the conventional motion sensing device Selective detection of dangerous objects is possible.

In the present invention, the predetermined reference value refers to a value obtained by quantifying the sensitivity of light received by an optical receiver of a size corresponding to a point where an approach distance at which the walker is determined to be dangerous to a dangerous object starts.

The dangerous object is not particularly limited as an object that carries a danger when approaching a walker carrying an infant, and may be, for example, a heating device, a stove, an electric rice cooker, a fan, or the like. It consists of a structure to attach.

In addition, by attaching the optical receiver to the wall of the place where the danger of approaching the walker or an object located in the place, it can be made of a structure that can detect the walker approaching the dangerous place.

The infant optical transmitter is mounted, and the optical transmitter is mounted in the number of one or two or more on the rim of the infant walker. That is, the optical transmitter may be attached to one walker in the front direction when the infant rides, in some cases, in consideration of the movement of the infant walker in a random direction, at least two or more optical transmitters They may be mounted at regular intervals on the rim of the walker.

In addition, when two or more optical transmitters are used, each optical transmitter emits a different color, and thus, a visual effect by various colors of light may be added.

The optical receiver includes a transmission antenna for generating a radio signal when the measured light sensitivity is greater than or equal to a reference value, and the alarm module includes a reception antenna for receiving the radio signal.

That is, the light emitted from the optical transmitter mounted on the walker is received by the optical receiver, and the sensitivity of the light is measured to generate a radio signal from the transmission antenna included in the optical receiver when the sensitivity of the light is higher than the reference value. The wireless signal is generated after receiving the radio signal from the reception antenna included in the alarm module, and the child is configured to have a structure in which the guardian recognizes that the walker is approaching a dangerous object.

The optical receiver is provided with a control unit for adjusting the predetermined reference value. That is, in order to adjust the distance at which the warning message sounds by approaching the baby walker to the dangerous object, a control unit may be added to adjust the predetermined reference value according to the magnitude of the dangerous object.

The alarm module includes a structure for generating an alarm message to the guardian, for example, a structure including a speaker, a vibration motor, or a lamp. Therefore, the alarm is made by the speaker, the vibration by the vibration motor, the light by the lamp, etc. It is made of a structure informing the walker to approach the dangerous object.

In some cases, the alarm module includes two or more of a speaker, a vibration motor, or a lamp, so that two or more of the alarm sound, vibration, and light are generated together, so that the guardian can easily recognize the danger alarm message. It may be done.

Hereinafter, although described with reference to the drawings according to an embodiment of the present invention, this is for easier understanding of the present invention, the scope of the present invention is not limited thereto.
