ES2421168B1 - Wireless warning using ZigBee technology - Google Patents

Abstract

The present invention relates to a "wireless alarm" which is about a bracelet or anklet responsible for emitting a small vibration and warning by a small LED screen, when one of the following events occurs at home: # - Ringing call of the door or telephone. # - Call to the home phone. # - Opening of the main door. # Therefore our invention consists of 5 main modules, 3 of them emitters (Doorbell module, telephone module and door module), 1 sender / receiver (vibrating wristband) and a data logger module in charge of communicating with a PC and storing the events that happen for a possible query, in which the date, time and type of event occurred will appear. # All This will be done using a wireless technology called Zigbee.

Description

Wireless Alert using ZigBee technology

Technical sector

The field of our invention is closely linked to wireless communications characterized by the total absence of any type of cable to transmit and / or communicate a series of data. Some examples of wireless technology are those that use Bluetooh or Wi-Fi technology.

State of the art

In the market there are currently several devices designed and configured to notify by wireless technology about different events. These devices have some characteristic similar to the present invention, as an example we can mention some of the most significant:

There is a vibrating bracelet that works with Bluetooth technology and alerts the user when their mobile phone receives a call or a message, very useful if the user loses sight of his cell phone. (U200502772)

We can also mention another vibrating bracelet specially designed for deaf people who warns them through Bluetooth technology of an event that takes place in your home. (P200800792)

As a novelty in our invention we can highlight that we will begin to apply ZigBee technology to be used by people with hearing impairment, with the advantages that such technology has.

Short description

The group of people with hearing impairment to which it is addressed, encounters many difficulties in their daily lives, to name a few, may not hear the home phone, the alarm clock, or the bell, may not find out when someone opens the front door ... an accumulation of events that hinder and hinder the lives of these people making them more vulnerable and dependent.

To increase independence and create a better ergonomics between the environment and this group of people, we propose to create a bracelet for the arm or leg that warns directly through vibration and / or through a small viewfinder to the user the origin of the warning or of a color code when an event of the aforementioned occurs and that in turn said events are recorded in a computer for future reference, being a complete system, including technology

to detect the events named above, (opening a door, ringing the bell, telephone ringing, etc ...)

Our product is essentially aimed at people with hearing problems of different nature, (including older people and people with low level of care)

Hearing impaired people: Either innate deafness, due to an accident at work, etc.

Senior citizens, where according to data, 30% of people over 65 have a hearing loss demonstrable by audiogram (preshiacusia).

People with hearing degeneration.

or simply people with low level of attention (distracted), who find difficulties in their daily lives and who have to use some means to improve their quality of life.

As you can see the range of possibilities is very wide and every day greater, due to excessive use of headphones in particular by young people, which produces a hearing degeneration at earlier ages, often due to misinformation (four of each Ten young people do not know that listening to music on their mp3 at full volume causes hearing loss) and other times in everyday life, where we find places like pubs, discos, etc ...) where noise and music often arrive at levels considered harmful.

The product can therefore interest both public bodies and end users.

In the present invention, ZigBee wireless technology of reasonable and safe reach is used, a booming and innovative technology that resembles the so expanded and known technology, the Bluetooh, but improving it in many aspects, such as:

-

Development of home automation with wireless technology

-

Important energy savings and the consequent battery life. (up to two years)

-

Good behavior with the environment, pollution O.

-

Technology without risk to the health of living beings.

-

Ease of use, adapted to people with certain difficulties in their daily lives.

-

Possibility of using it and / or adapting it to numerous fields that have nothing to do with home automation, such as industry, security systems and alarms, hospitality ... etc.

Detailed description.

Wireless alarm using ZigBee technology, which is the name of the specification of a set of high-level protocols for wireless communication for use with digital broadcasting,

20 It is based on the IEEE 802.15.4 standard of personal area wireless networks, with applications that require secure communications with low data delivery rates and maximization of battery life, aspects that fit perfectly within the objectives. of our project.

As previously mentioned so that these communications can be taken to

In addition to the corresponding transmitters and receivers (we will use XBee systems that use this technology) we need several devices to successfully carry out the objective of our project.

Our invention consists of one or several transmitter modules (1), a receiver module for the user (2) and an event receiver module for data recording (3)

30 responsible for communicating with a PC and storing the events that happen for a possible consultation, in which the date, time and type of event occurred will appear. Next we will explain the details of each module.

-

Emitting Modules (1) Each of them will be powered in such a way that through the use of a voltage regulator we can deliver a continuous voltage of 5V (6), which is introduced directly to the PIe (7) and the regulator circuit of the XBee (8) (Remembering that the XBee module is powered by 3.3V).

This module sends a signal through the XBee module (8), having previously been processed by the PIe (7), when the activation of the sensor / actuator (9) occurs.

10 -Receiver module for the user. (2)

Through the supply of a DC battery (6), we manage to supply the PIe {7) and the XBee (8) with a continuous voltage of 5V, which is introduced directly to the PIe and the XBee regulator circuit (Remembering that the XBee is powered by 3.3V). Then we will connect a vibrating motor (11) to warn

15 to the user and an LCD screen (10) to indicate to the user through a brief written message) the type of event that has happened.

-

Data Registration Module. (3)

Through the XBee, and the configuration of a board made for this purpose, the events are stored in a file whose communication with the PC (5) will be done by connecting to the USB port (4) using a previously programmed software.

Examples of embodiment

An example of embodiment of the invention that is not limited in scope is set forth below.

2S When calling the doorbell of the house door, we close a circuit in which we feed the PIC at 5v and this in turn, previously programmed, instructs the installed XBee module to emit a signal to our receiver module for the user, once that the wireless signal arrives at the XBee of this module, the microprocessor (which is powered by a 5v battery) orders that the small vibrating motor be put into operation

30 emitting a vibration to the user and in turn orders the small screen of the LeD to indicate to the user the type of event that has occurred, in our case a text message "Doorbell" would come out.
