Description

Security system for mobility of people.

Technical sector

The invention belongs to the systems of safety of persons with disabilities when passing vehicles and before urban and architectural obstacles.

Background of the invention

In the state of the art we find a series of inventions or patents that are related to safety and assistance to disabled people:

To start is the SESAMONET system developed by the Joint Research Center of the Commission European It consists of a system with the same objective but which is based on the use of RFIDs (radio frequency identification). This system tries to get blind people guided by beacons formed by sensors called RFID that are installed on the ground and using an antenna on the cane and a smat Phone warn the blind person of possible obstacles such as platform or the arrival of a train. The SESAMONET system only allows notify the blind person himself, does not contemplate informing others people (security personnel, drivers, etc.) of eventualities that could occur or interact with others devices in case of danger (audible alarms, systems fall arrest), difficulty (ramp activation), etc.

The advantages of the present invention are older, since it not only manages to notify the person disabled from possible obstacles or problems, but notifies the train, bus and driver, to building security personnel or public facilities of the presence of the disabled, of such so that a series of mechanisms are activated that help to help the person with difficulties such as ramps, sound systems and fall arrest systems, among others. It is compatible with other technologies and in particular it allows to incorporate RFIDs.

ES 2156518 A1 describes a security system of urban movements of blind people using a device on the cane that emits acoustic or vibrating signals when moving away or approach areas with bands of indelible paint with material iron.

ES 1040770 U consists of a bulky plate signage for the blind consisting of sheets of some material that allows to provide information to the general public of the presence of the blind person, so that they can help. The warning occurs indiscriminately without particularize the recipients who should receive such notice. It attracts attention without properly safeguarding the privacy of the disabled person.

ES 2161149 A1 consists of a procedure for guide blind people through a series of touch panels installed near public roads. The panels implement a map of the surroundings by means of elements in relief and signals in braille. The panels are passive devices and must be their own blind who should interact with them.

Description of the invention

In view of the limitations detected in the prior art, it would be desirable to have a system and devices that allow broader, more versatile communication and safer to protect disabled people. Too You can extend your employment to other situations in the normal life of citizens with difficulties but without permanent disabilities.

Faced with common security systems, this invention implements an active safety method that involves the knowledge on the part of the train and the driver (or the bus and driver) or building and facility security personnel of the presence of a disabled person to help you in your mobility and access (ramps, sound devices, systems fall arrest, etc ...) and allows the performance of the driver or staff security, if applicable.

Passive security and guidance systems current do not get the entire set involved aware of the danger situation, the operator or the system does not appreciate that the person with difficulties is close and do not activate Possible barrier mechanisms.

The present invention has a mechanism active for both the disabled person or with difficulties such as for the vehicle and the driver or security personnel who can be aware that they must act while being more aware of specific situations of danger.

The invention relates to a device preferably small in size, easily transportable and can be incorporated into either a wheelchair or a cane or a backpack, belt or shoulder strap, for example. It has a series of elements that allow direct communication between person disabled and vehicle using as half waves electromagnetic that transfer data between the two dispositives.

In turn, the present invention can read the information received from RFIDs for coupling our system With current systems.

Energy consumption is very low, just one Small battery like mobile phones.

The present invention allows great versatility of use since it allows to send a great variety of signals: it can transmit information to the vehicle, to the security center of the building or installation on the type of disability or difficulty, the status, destination station, topography and location of the obstacle in an access, among others, and to the person disabled or with difficulties giving you information about routes, itineraries, alternative roads, situation of impediments in access, traffic, among others.

These results are achieved through the technical characteristics defined in the claim Independent. Preferred embodiments are specified, in turn, in the dependent claims.

Preferred Embodiment of the Invention

The following is described, with reference to the figures, an exemplary embodiment of the invention without character limitative.

For example, the figures relating to the cane or Disabled wheelchairs can also extend to a baby carriage, or a bag or backpack of an advanced person age, etc.

The exposed embodiment will be better understood in A situation like the following. The disabled person or with difficulties (24) approaches a platform or the edge of the bus stop bus, or access to public facility or building or obstacle for works on a road, through a series of devices integrated in the cane (23) or in the wheelchair (4) - also it could be in a baby carriage, a backpack, belt, or others, can notify the vehicle (2) or security center of their presence, where appropriate, so that the driver activates the help mechanisms as (ramps, fall arrest systems, sound systems, etc ...) and the driver stays on alert and notifies the security service of building or facility to mobilize support services and help.

The sign starts from the cane (23) or the chair of wheels (4) from its transmitter (11) and reaches the on-board receiver (17) of the vehicle (2) or security center (22) that transmits the signal to the control system (21) which manages said information to Perform the relevant actions. Such actions can be: activate an actuator (19) by means of the on-board transmitter (16) that produce relevant actions to help the disabled (24) or transmit information through the on-board issuer (16) so that the portable receiver (12) carried by the disabled person (24) receive the information and transfer it to the process unit portable (13) which is responsible for notifying or informing the disabled (24).

The actions that the onboard device (22) you can carry out on your own, they are multiple, for example, you can interact with active security systems (systems barrier, fall arrest systems, through acoustic signals, ramps disabled access, etc.) that are activated when the unit central (21) of the vehicle (2) receives the signal that the person with Difficulties are at the stop.

On the other hand, the portable device (10) implements mechanisms to notify the disabled (24). Between others, through voice messages, a beep code indicative of the type of obstacle to be saved. This can happen through a speaker or headphones that the person will wear disabled Other possibilities would be through text in a display of the portable device or through a vibration that can be perceived

The portable device (10) emits signals preferably periodically, in this way the device on board (22) that is in listening mode, upon receiving said Waves come into operation thus beginning the interaction.
