Description

CHILD SECURITY SYSTEM

The present invention relates to a system of

child safety, which includes a module for an adult

5 and a module for a child, which allows to determine the separation distance between both modules, and also includes a water detector to notify if the child has fallen into a pool.

10 BACKGROUND OF THE INVENTION

Child safety is an essential aspect

for parents and adults who are responsible for some

boy.

fifteen

In crowded spaces it is important to know that

the child does not move more than a predetermined distance from the

responsible adult to avoid possible losses or

Kidnapping of children.

There are currently different systems of

twenty

security that allow to determine the distance of

separation between a responsible adult module and the

module that the child carries.

For example, US Patent 2005280546 Al

describes a personal proximity alert system that

25

includes a first mobile unit and a second mobile unit

that communicate with each other to determine their distance from

separation.

The main drawback of the alert system

described in this document is that it is not possible to determine

3 o

the direction in which a unit of the

other. In addition, the safety distance between the two

Units is fixed and excessively short, about 10 meters.

On the other hand, another aspect that presents a

Child safety risk is the risk of falls from

35

Children in pools.

At present it is known that a large number of

children

they fall accidentally in swimming pools with serious

consequences.

For

detect the drop from children in swimming pools

exist

modules from alarm that warn from its immersion in

Water.

For example, US Patent 5138300 describes a water immersion alarm system comprising a transmitter carrying unit and a water sensor for a child.

The drawback of these alarm systems is that they only serve as fall detectors in swimming pools, but do not incorporate alarms for safety distance or systems to locate a child who has been lost.

Therefore, it is evident the need for a global child safety system, which allows to determine if a child moves too far away from an adult, to locate it in the event that it has been lost and to warn in the event that it is in contact with water, especially if it has fallen into a pool.

DESCRIPTION OF THE INVENTION

With the security system of the present invention, the aforementioned drawbacks are resolved, presenting other advantages that will be described.

The child safety system of the present invention comprises a module for an adult and a module for a child, both modules being wirelessly connected to each other, the module comprising the adult an antenna, which detects the separation distance between the module of the adult and the module of the child, and is characterized by the fact that said module for the child comprises a water detector connected with said module for the adult.

Advantageously, said module for the adult comprises a directional antenna associated with a location button, which determines the direction in which the module for the child is located.

In addition, said module for the adult also comprises a push button for selecting a safety distance between both modules, which increases the power of said distance detector.

Advantageously, said module for the adult

10 comprises an indicator of the safety distance of up to 500 meters, the safety distance can be increased at the will of the adult every 25 meters. Said module for the child also advantageously comprises an emergency button, which sends a

15 notice to the module for the adult. Thus, the child can notify the adult in the event of any emergency situation.

Said modules for the adult and for the child are preferably connected to each other wirelessly by radiofrequency. The child safety system of the present invention has the following advantages: It allows to locate the module for the child in a clear and concise manner, indicating the direction in which the module for the child is located;

-

It allows the adult to be notified immediately if the child moves more than a predetermined safety distance, which can be adjusted at the will of the responsible adult;

3 O This security distance can be adjusted up to a maximum of 500 meters; It is completely independent, does not require GPS or telephone connection; Notify immediately if the child is in contact with water, for example if it has fallen into a

pool.

DESCRIPTION OF A PREFERRED EMBODIMENT

The child safety system of the present invention consists of two modules, one for the responsible adult and one for the child.

The module of the responsible adult 1 is represented in Figure 1 and is approximately the size of a mobile phone, while the module for the child is represented in Figure 2 and is in the form of a bracelet.

The adult 1 module comprises the following components:

A radio frequency transmitter / receiver (not shown in Figure 1), so that all transmissions are made by radio frequency;

a function communication antenna

standard

(not represented in Figure 1), by example a

antenna

omnidirectional, that It allows to transmit the

following

functionalities:

to.

Calculate distance;

b.

To receive the signal from emergency of module of the

boy

2;

C.

To receive the signal from drop in a pool of the

module

of the boy 2;

a

antenna from location directional (no

represented

in the figure one), that to the activate is

necessary

move he module of the adult in all the

directions, until the strongest signal of the child's module is found. In this way, it is possible to determine the direction in which it is located. The transmission of alarm signals is still received with the directional antenna;

-

a distance indicator 3, which reports the distance at which the module of the child 2 is at all times;

a water indicator 4, which immediately warns that the child's module has come into contact with water;

-

emergency indicators 5, which indicates whether the child has pressed the emergency button incorporated in the module of the child 2;

-

a location button 6, which activates the directional antenna. It is necessary to activate this button 6 to enter this mode;

-

distance limit button 7, which allows you to specify the allowed control distance from the adult module. In this way, in 25 meter sections,

It is possible to specify the safety distance. If the child moves further than that distance, the adult module will indicate that the child has moved further than allowed through a safety distance indicator exceeded 8;

-

an on / off button 9;

-

a power supply (not shown in figure 1), which feeds all the electronics it contains, with its corresponding charge indicator 10; -a charge indicator 11 of the child's module

2 . For its part, the module of child 2 comprises the following components:

a radio frequency transmitter / receiver (not shown), since all transmissions are made

through

radiofrequency;

-

a antenna (no represented) integrated in its

circuit

printed, that It allows he Shipping Y reception from

signals;

a

button from emergency 12 for Send

a

notice

from emergency to the module of the adult one;

-

a detector from Water 13, that active a logic

which generates an emergency signal in the adult module

one ;

an on / off button (not shown); -a power source (not shown), which feeds the module electronics.

To determine the distance at which the module of the child 2 is with respect to the module of the adult 1, a constant analysis of certain parameters is carried out, according to the following logic (specified in Figure 3)

The receiver / transmitter of the adult module has the selection button for the distance of

security 7 that allows to change the transmission / reception power.

It has been calculated that each power jump increases the reception distance of the signal by about 25 meters.

The module of adult 1 begins by sending a signal to the module of child 2, at its minimum power.

In the case that the module of the child 2 answers correctly, it is indicative that it is within the range of the minimum distance.

In the event that the module of the child 2 does not answer, it indicates that it is further away from the power range and is not receiving the signal from the module of the adult 1 correctly and is not able to interpret it. Consequently, the adult module 1 increases the emission power by one point and repeats the signal sending.

In the case that the module of the child 2 answers, it implies that it is further from the just previous power level and within the limits of the just higher power level.

In case the module of the child 2 does not answer, the process is repeated until the distance at which it is found can be determined.

If it is at a distance greater than that specified as a safety distance, an alarm is generated, which will be seen in the adult module in the indicator 8 that the safety distance has been exceeded.

The overall operation of the system is as follows:

The module of adult 1 is constantly consulting the module of child 2 to determine the distance it is.

The module of child 2 is constantly

listening to the requests of the module of the adult 1. At the same time, if an emergency warning or a contact with the water is detected, it immediately sends a signal to the module of the adult 1, indicating that warning in the

5 corresponding 4 or 5 indicator.

It should be noted that the information may not reach the module of adult 1 due to a transmission error, etc. Therefore, at the end of the distance detection process, all states are forwarded

10 pending to ensure that alarms are sent correctly). In the event that the module of the child 2 moves away from the safety distance specified in the module of the adult 1, it triggers an alarm informing the adult of

15 that the child has moved away from the safety distance by means of the corresponding indicator 8. In the event that the module of the adult 1 detects any of the alarms communicated by the module of the child 2, alarms are activated that inform the adult

20 so you can react. As the distance sensing process is constantly running, it is guaranteed that if the module of the child 2 is within the possible technical range (500 meters) it will be able to communicate with the power

25, and the status of the water detection, the state of the emergency button 12 and the status of the power supply of the module of the child 2 are included in this transmission, which are shown in the corresponding indicators 4, 5 and 11 in the adult module 1.

3 O Figures 3 to 5 show the operating processes. In particular, the distance detection process is shown in Figure 3, the operation process of the adult module 1 is shown in Figure 4 and the process is shown in Figure 5

35 operating the child's module 2.

Although reference has been made to a specific embodiment of the invention, it is apparent to one skilled in the art that the described child safety system is susceptible to numerous variations and

5 modifications, and that all the mentioned details can be replaced by other technically equivalent ones, without departing from the scope of protection defined by the appended claims.
