OBJECT OF THE INVENTION
[0001] The invention, as set forth in the statement of the present specification, relates
to an electronic equipment for the identification, control and safety of groups of
individuals in mobility, imparting to the function it is intended to, remarkable advantages
and innovative characteristics, compared with other systems currently known in the
market for the same purpose.
[0002] More particularly, the object of the invention focuses on a equipment with electronic
devices which, being applicable for groups of children, old people, disabled people,
tourists, etc., in excursions, guided tours, spare time trips, camps, or other activities
requiring the group's mobility, and being basically formed by a mobile device controlled
by the person responsible of the group and a plurality of devices with RFID label
(which stands for
Radio Frequency Identification), preferably consisting of a number of bracelets, worn by each one o the group's
individuals, is aimed to constitute a system for the identification, control and safety
of said group of individuals in said circumstances of mobility in a continual and
autonomous way, allowing the person responsible of said group to keep in every moment
under control to each and every one of the group's members, both in a overall way
and individually, allowing the person, furthermore, among other advantages, to have
access to further information about different aspects of each one of said individuals.
APPLICATION FIELD OF THE INVENTION
[0003] The application field of the present invention is framed within the technical field
of radio frequency identification technologies, applied to the safety of groups of
people in mobility. These technologies are usually known as RFID
(Radio Frequency Identification).
BACKGROUND OF THE INVENTION
[0004] As it is known, RFID (which stands for
Radio Frequency Identification) is a remote data storage and recovery system which uses devices called labels, transponders
or RFID tags. The main purpose of the RFID technology is transmitting the identity
of an object (similar to a unique serial number) through radio frequency waves. The
RFID technologies are grouped within the so called Auto ID (Automatic Identification).
[0005] A RFID label is a little device, similar to a sticker, which can be adhered or incorporated
to a product, animal or person. They contain antennas in order to allow them to receive
and answer to radio frequency demands from a RFID transmitter-receiver, frequently
called RFID readers. The passive labels have no need of inner electrical supply, whilst
the active ones do have this need, using usually a battery to this end. One of the
advantages of using radio frequency (instead of, for example, the infrared technology)
is that a direct view between transmitter and receiver is not required.
[0006] Based on this technology systems are appearing which allow, detecting the transit
of people (passive RFID), or locating people within an area (active RFID), providing
more complete traceability and safety solutions.
[0007] In the state of the art we find:
- Systems for tracking people with fixed infrastructures and based on active RFID:
Utility Model ES 1064033 U, ES Patent 2303465. These are composed mainly of an infrastructure of readers and antennas located in
the transit zones for people, which are provided with an active RFID card which is
identified when the person transits by the zone with antennas. These systems allow
a certain distance (typically of a few meters) between tag and antenna for a correct
identification.
- Systems based on objects identification using mobile readers: Patent IP 0700437, ES 2159502. These are composed of a mobile device acting as RFID reader which allows, at higher
(active RFID) o lower (passive RFID) distance, the control mainly of objects.
- Systems based on the detection of objects moving away: Patent IP 0700437. Systems which detect the movement of an object away form a central reader.
- Systems for the safety of objects: ES patent 2280888. Systems based on RFID for preventing objects from being theft.
[0008] Therefore the RFID technology is combined in a different way to obtain different
solutions:
- Infrastructure of antennas and fixed readers for the identification of the transit
of passive (with action by the user) or active (for the automatic detection of the
transit of people and objects) RFID tags. It allows the traceability and/or the tracking
down of people and objects.
- Utilization of Mobile RFID readers, used mainly by individuals, for the identification
of people and objects using mainly passive RFID tags and through the approaching of
the RFID reader.
- Use of fixed and mobile RFID readers for detecting the movement away of active RFID
tags, with antitheft safety purposes.
[0009] The combination and the different use of the RFID technology offers various solutions
for problems of objects and people identification, traceability, tracking down, control,
safety, etc., however, in the current state of the art it is found no document or
patent which, as the invention herein proposed, gives a solution for the following
general situation:
- Group of individuals assigned to one (or several) person(s), responsible for their
safety in determined timeframes.
- Both the group and the responsible have geographic mobility at any level (inside a
building, outdoor enclosure, unenclosed space, displacements between distinct geographic
locations, etc.).
- the individuals of the group are exposed to get lost, want to escape from the group's
discipline, stay forgotten in a place once the group has left it, or their identification
being necessary for accessing to relevant data (identification, medical, familiar
environment-related, contact data, etc.)
[0010] Therefore, the objects of the present invention are:
- The remote identification (meters) of the individuals by the responsible in order
to:
* Control the presence of the individuals of the group both specific (group listings,
on demand of the responsible) and continuous (safety radius, in an autonomous way
without needing the interaction by the responsible)
* Search for lost individuals
- the identification in a short distance (centimetres) of the individuals by the responsible
for the:
* Univocal identification of the individual
* Access to critical data (medical, familiar environment-related) for safety in situations
such as possible allergies to meals, environment or medication, picking up by unauthorized
people, etc.
[0011] The current state of the art does not solve all the challenges posed for covering
the described situation:
- allowing the differentiation between remote identification (meters) of the individuals
and identification by approaching (centimetres) the RFID reader or receiver to the
identification tag or bracelet. The RFID technology is thought for identification
without differentiating the distance. A system identifies or not, without considering
the distance, only in case of reception or not in a RFID reader of the signal transmitted
by a tag.
- Allowing the continuous identification in time and in mobility of all the components
of the system.
- Manage the identification and the information for the control of specific and continuous
presence.
[0012] Thus, therefore, by the applicant, it is unknown the existence of any other invention
presenting technical, structural and configuration characteristics similar to the
ones presented by the electronic equipment for the identification, control and safety
of groups of individuals in mobility herein proposed, whose characterizing and distinctive
details relating to what is yet known, are exhausted developed below and are conveniently
collected in the final claims accompanying the present specification.
EXPLANATION OF THE INVENTION
[0013] Thus, therefore, and as has been pointed previously, the invention proposes an electronic
equipment for the identification, control and safety of groups of individuals in mobility
which constitutes a tool for tracking down, identification and safety of a group of
individuals in mobility in a continuous and autonomous way, allowing to a person have
in every moment under control each and everyone of the group's persons.
[0014] The equipment is intended to being applied in caring of groups (children, old people,
disabled people ...) in excursions, guided tours, group trips, camps, spare time places,
etc., preventing the risk of some of the group's components getting lost, besides
of having a database of interest for each person.
[0015] To this end the equipment comprises, basically, a mobile device, consisting of a
PDA or of a UMPC, which the person responsible of the group works with and which is
provided with a SD type memory card, and a plurality of devices with transceptor or
RFID label, preferably consisting of bracelets, worn by each one of the group's individuals,
being contemplates a PC in which a computing application is incorporated and a repository
in order to allow the management of the individuals, of the groups, and the assignment
of bracelets, as well as the possibility of managing information from different group
responsibles, access permissions to the information, etc. The mobile device is able
to synchronize the information managed in the PC for its subsequent use.
[0016] Thus, for example, in a possible use of the equipment, wherein a group of children
goes for an excursion, a monitor or responsible of the group posses a mobile device
(PDA or UMPC) whilst the children, each one, wear a bracelet. The bracelet emits periodically
an identification signal received by the mobile device if they are within a range
of about 20 meters.
[0017] Thanks to the continuous reception of the bracelets' identification, the monitor
gets access to different functionalities:
- Lists Control: the responsible shall be able to make an entry listing of the children
at the beginning of the excursion, check at any time that all the children are in
a close radius and, at the end of the excursion, make an exit register of the members.
To this end, the responsible just pushing a button shall be able to "call register"
so that the mobile device identifies all of the bracelets being in the surrounding
area.
- Individual Control: besides the "group" lists control explained above, one shall be
also able to make a listing, one by one, of the users with bracelet, by approaching
the mobile device to each bracelet of each child.
- Individual Information: the monitor, by approaching the mobile device to the bracelet,
shall have access to data related to the bracelet's user (name, surname, information
of interest, as for example people authorized for picking up a child, medical data,
etc.).
- Safety Radius: the mobile device shall be able to warn the monitor if any of the children
was not detected during a determined period of time (for example 2 minutes), in order
to prevent a child from getting lost.
- Search for a child: the monitor shall be able to select a child so that the mobile
device searches for the signal of a child who can have got lost.
[0018] Beside the described functionalities, a PC application is provided, allowing the
management of the individuals, of the groups, and the assignment of bracelets, as
well as the possibility of managing information by the monitors, permissions for accessing
to the information, etc. The mobile device is able to synchronize the information
managed in the PC for its subsequent use described in the above points.
[0019] Additionally, it is contemplated the possibility of incorporating to the equipment,
as long as the circumstances allow it, being particularly optimal for its use indoor,
one o more beacons fixed in the area to be monitorized, thus getting a higher coverage
and, even, the advantage of being able to track down, in certain defined areas, where
the bracelet is in every moment located.
[0020] Briefly, the advantages of the invention in relation with the current state of the
art are essentially the following:
It is a mobile identification electronic equipment based on radio frequency comprising
a plurality of identification bracelets (one by each member of the group) small in
size, provided with a RFID label for sending periodically identification signals and
a mobile device allowing, by the use of a SD (secure digital) type memory card, the
reception of the RF identification signals transmitted by the identification bracelets,
as well as the data treatment.
[0021] Moreover, it is contemplated the existence of a PC computer, for managing the data
of the individuals and of the identification bracelets and its relationships.
[0022] The aforementioned mobile device can be a PDA or UMPC
(Ultra Mobile PC) or any portable device with a slot for SD card, being able to receive the identification
signals from one or more identification bracelets, as well as to discriminate the
potency of the received identification signals, being able to distinguish if it is
in a distance of meters or centimetres by potency threshold of the received signals.
[0023] It is to be remarked, furthermore, that the mobile device can receive in a continuous
manner the identification signals without needing of interaction by the responsible
user, and synchronizes itself with the computer's information.
[0024] The mobile device, through the SD card can distinguish specifically which received
identification signals from the bracelets are within its coverage radius in order
to known which bracelets (or individuals wearing them) in order to known if anyone
is missing, being able to make group listings of the entry of individuals, specific,
and of the exit.
[0025] The mobile device can warn if one or more bracelets have not been received in a determined
time (safety radius).
[0026] Furthermore, thanks to the SD card and to the possibility of differentiation of the
signals potency, it implements the search of one or more bracelets (or individuals
wearing them).
[0027] The mobile device allows, by the possibility of distinguish whether the bracelet
is in a centimetres range of said device, identifying a bracelet and showing the data
(personal, medical, environmental, etc.) corresponding to the individual wearing it.
[0028] The described electronic equipment for the identification, control and safety of
groups of individuals in mobility represents, then, an innovative structure with structural
and constitutive characteristics unknown so far to this end, reasons which in combination
with its practical utility, provide it with enough basis to obtain the exclusivity
privilege which is applied for.
BRIEF DESCRIPTION OF THE DRAWINGS
[0029] In order to complement the description being fulfilled and with the aim of helping
to a better understanding of the characteristics of the invention, the present specification
is accompanied, as an integral part thereof, by a set of plans, in which by way of
illustration and not of limitation, is represented the following:
Figure number 1.- shows a schematic view of the three basic elements of the equipment
object of the invention and theirs interactions: identification bracelets, which emit
the identification signal, received by mobile devices, which can synchronize the information
with the PC.
REALIZACIÓN PREFERENTE OF THE INVENTION
[0030] In light of the mentioned figures, and according to the numbering taken on them,
it is noted how the device in question comprises the following elements:
A plurality of bracelets (1) with RFID label, a mobile device (2) with SD card and
a PC (3).
[0031] The PC (3) is a personal computer where the system's managing software is installed,
for which it is provided with a application in which one shall be able to manage all
the devices and users of the system, as well as the a data repository which shall
include the data of the application.
[0032] On its part, the mobile device (2) can consist of a PDA or of a UMPC (UltraMobile
PC with or without keyboard) and, through the SD type memory card, will allow the
control of the bracelets (1) according to the configuration made in the application
of the PC (3), so that it will allow the display of the data and the control of the
bracelets (1) with the corresponding functionalities, while the data repository contains
a replica of the PC's database (3).
[0033] The mobile device (2) PDA or UMPC, as it is represented in figure 1, synchronizes
the data of the database managed in the PC (3), so that, from the identification signals
transmitted by the bracelets (1) and the data of the data repository can offer the
functionalities of lists control, individual control and identification, search and
safety radius.
[0034] Talking about the bracelets (1), each one of them has a PCB (Printed Circuit Board)
as a support for a transceptor or RFID label, i.e., of radio frequency based on the
standard IEEE 802.15.4 (such as the CC2430 type from Texas Instruments) plus the additional
components needed for its operation (2 crystals for the watches, decoupling capacitors,
polarization resistors, adaptation for the RF port and antenna).
[0035] The antenna is, for example, an antenna in microstrip adapted by a commercial balun.
[0036] The whole device is fed through a battery holder for a watch battery.
[0037] Each bracelet (1) transmits an identification frame, containing the information on
the MAC address of the transceptor chip of radio frequency or RFID label and the value
of the battery, resting between frames in low consumption mode.
[0038] To this end the bracelet's firmware consist of four different blocks:
- Radio frequency control
- Timing of tracking down frames
- Button control
- Battery control
- The radio frequency control block is in charge of the transmission of ZigBee frames.
- The tracking down frames timing block is in charge of the randomization of the time
between frames in order to prevent collisions and builds the tracking down frame to
be transmitted. It also includes the data of the battery level in the frame.
- The button control block runs the interruption attention routine when the bracelet's
button is pushed.
- The battery control block monitorizes the battery level and determines whether said
value is above the minimum value for the operation of the bracelet.
[0039] On its part, the SD type memory card the mobile device (2) is provided with is, for
example, a ZigBee-SDIO card, and consist of a PCB as support, for example a CC2430
from Texas Instruments, plus the additional components needed for its operation (2
crystals for the watches, decoupling capacitors, polarization resistors, adaptation
for the RF port and antenna).
[0040] The antenna is, for example, a microstrip antenna adapted by a commercial balun.
[0041] The device is fed through the SD interface being introduced in the Host's slot, i.e.,
of the mobile device (2).
[0042] The firmware of the mobile device (2) consists of two different blocks:
- RF control
- Interface SDIO control
[0043] The radio frequency control block is in charge of the reception of ZigBee frames.
When a frame is stored and in the control block of the SDIO interface an event is
generated, so that this generates an interruption to the host.
[0044] The SDIO interface control block manages the communications through the SD interface
generating the answers to the received commands.
[0045] In case that the mobile device (2) is a PDA, this one, whose only requirement will
be that it has a operating system compatible with the application of the PC and it
contains a slot for the SD memory card, thanks to the continuous reception of the
identification from the bracelets (1), offers the following functionalities:
Lists control: it allows making an entry listing of the bracelet wearers (1), checking
at any time whether all the bracelet wearers are within a close radius and an exit
register of the members.
- Individual control: besides the "group" lists control explained above, one shall be
also able to make a listing, one by one, of the users with bracelet, by approaching
the mobile device to each bracelet.
- Individual Information: the monitor, by approaching the mobile device to the bracelet,
shall have access to data related to the bracelet's user (name, surname, information
of interest, as for example people authorized for picking up a child, medical data,
etc.).
- Safety Radius: the mobile device shall be able to warn the monitor if any of the children
was not detected during a determined period of time (for example 5 minutes), in order
to prevent a child from getting lost.
- Search for a user with a bracelet: allows the selection of a user with a bracelet
so that the mobile device searches for the signal of a child who can have got lost.
- Synchronization with the PC's database: it allows synchronizing the data from the
PC's database managed by the application, so that in the PDA one has the data of the
bracelets, of the bracelet wearers, and theirs relationships.
[0046] The same functionalities offered in the PDA, are offered for small sized computers
such as the
UltraMobilePC (UMPC). Therefore, through the UMPC it is also possible to make:
- Lists control
- Individual control
- Individual information
- Search
- Safety radius
[0047] Any UMPC commercially available can be used, which has a 7 inches screen, compatible
operating system and SD slot.
[0048] The PC's application, on its part, allows the management of the users wearing the
bracelets and of the bracelets, by offering:
- Managing of the users: allows the creation, modification, and deletion of the data
of the users.
- Managing of groups: allows the management of the users in groups.
- Managing of bracelets: allows the creation, modification, and deletion of the data
of the system's bracelets.
- Assignment of bracelets to the users: allows the assignment of the bracelets to the
users for their subsequent relationship in the identification and other functionalities
offered in the PDA and the UMPC.
- Synchronization: in order to allow the data synchronization.
[0049] Finally, it can be highlighted that, additionally, it is contemplated the incorporation
to the equipment of one ore more beacons (not represented in figures) fixed to the
area to be monitorized, intended to get a higher coverage and be able to track down
in certain defined areas where is each bracelet in each moment, being composed of
a PCB as support (for example a CC2430 from Texas Instruments), plus the additional
components needed for its operation: two crystals for the watches, decoupling capacitors,
polarization resistors, adaptation for the RF port, alimentation and antenna.
[0050] Having sufficiently described the nature of the present invention, as well as a way
of putting it into practice, it is not considered necessary to make a more extensive
explanation in order that any expert in this area will understand its scope and the
advantages that can be derived from it, making known that, within reason it could
be put into practice in other embodiments differing in detail from that indicated
by way of example, and which will obtain the same degree of protection, provided that
they do not alter, change, or modify its fundamental principle.
