at least one second fixed radio device receiver/transmitter, said first fixed radio device being a master device and the at least one second fixed radio device being a slave device,

said remote server being connected to only said master device,

said master device being connected to said slave device,

said slave device and said master device both being connectable with said first mobile radio device, said first mobile radio device being adapted to receive from said master device and/or said slave device at least one voice audio message on information about the environment,

said first mobile radio device being adapted to be housed in a first wearable accessory,

a second mobile radio device receiver/transmitter,

said second mobile radio device being housed in a second wearable accessory,

said second mobile radio device being adapted to connect with said first mobile radio device and to receive from said first mobile radio device said at least one voice audio message,

said second mobile radio device being adapted to communicate said at least one voice audio message on information about the environment to said user wearing said second mobile radio device to allow the user to orientate oneself in moving in open/closed spaces in safety,

said first wearable accessory and said second wearable accessory leaving the user's hands always free,

wherein the master device is positioned in an open or closed space equipped with WI-FI connection to connect to said at least one remote server, said at least one remote server comprising at least information about the user, the master device, the slave device, the first mobile radio device, the second mobile radio device, positions of the master device and slave device, identification of the master device and slave device in relation to the respective positions and the first and second mobile radio devices.

2. The orientation aid system for blind people according to claim 1 , wherein said first mobile radio device comprises at least two radio modules.

3. The orientation aid system for blind people according to claim 1 , wherein said first wearable accessory is a bracelet, a watch, a necklace, or other device suitable for being wearable without encumbering the hands of the user and said second wearable accessory is an earphone, a necklace or other device suitable for being wearable without encumbering the hands of the user.

4. The orientation aid system for blind people according to claim 1 , wherein said first wearable accessory also comprises a gyroscope.

5. The orientation aid system for blind people according to claim 1 , and further comprising a further fixed auxiliary device comprising a radio receiver/transmitter device and comprising a warning device suitable for sending audible and luminous warnings.

6. The orientation aid system for blind people according to claim 1 , wherein said second mobile radio device comprises a loudspeaker and is included in the second wearable accessory.

7. The orientation aid system for blind people according to claim 2 , wherein said at least two radio modules include Bluetooth modules.

8. The orientation aid system for blind people according to claim 6 , wherein the second wearable accessory is an earphone or an earring, is suitable to be integrated in a hat or in an arm of a pair of glasses, or includes a clamp or pin for affixing to the user's clothing, where it is audible to the user.

9. The orientation aid system for blind people according to claim 1 , wherein the at least one slave device is configured to connect to said master device, when said slave device is at a distance covered by the radio signal of the master device, and to be able to be linked via radio by said first mobile device when the user is at a given distance from said slave device to transmit said voice audio message to said first mobile device.

10. The orientation aid system for blind people according to claim 1 , wherein said first mobile radio device comprises a button for listening to the voice audio message received when it has entered the field of action of said slave device.

11. A method for implementing an orientation aid system for blind people, comprising:

providing the orientation aid system for blind people, comprising:

a first fixed radio device receiver/transmitter, positioned in any open or closed space and a first mobile radio device receiver/transmitter, and a remote server connected only to the first fixed radio device, said first mobile radio device being supplied to at least one user,

at least one second fixed radio device receiver/transmitter, said first fixed radio device being a master device and the at least one second fixed radio device being a slave device,

said remote server being connected to only said master device,

said master device being connected to said slave device,

said slave device and said master device both being connectable with said first mobile radio device, said first mobile radio device being adapted to receive from said master device and/or said slave device at least one voice audio message on information about the environment,

said first mobile radio device being adapted to be housed in a first wearable accessory,

a second mobile radio device receiver/transmitter,

said second mobile radio device being housed in a second wearable accessory,

said second mobile radio device being adapted to connect with said first mobile radio device and to receive from said first mobile radio device said at least one voice audio message,

said second mobile radio device being adapted to communicate said at least one voice audio message on information about the environment to said user wearing said second mobile radio device to allow the user to orientate oneself in moving in open/closed spaces in safety,

said first wearable accessory and said second wearable accessory leaving the user's hands always free,

wherein the master device is positioned in an open or closed space equipped with WI-FI connection to connect to said at least one remote server, said at least one remote server comprising at least information about the user, the master device, the follower device, the first mobile radio device, the second mobile radio device, positions of the master device and follower device, identification of the master device and follower device in relation to the respective positions and the first and second mobile radio devices,

providing that the user wear the first and second mobile radio devices,

connecting the master device to a remote cloud server via radio,

connecting the master device to the slave device via radio,

connecting between the first wearable accessory and the second wearable accessory via radio,

registering on the cloud server of the first and second fixed radio devices, the first and second mobile radio devices combined respectively with the first and second wearable accessories, along with credentials of the user,

configuring and personalizing the master device and the slave device as markers, or to signal a place/situation, with data to be sent to at least one chosen from the first and second wearable accessories,

recognizing the first wearable accessory by data present in the cloud server, stored during registration, subsequent connection between the first wearable accessory and the slave device when the first wearable accessory enters a radio field emitted by the slave device,
