Abstract
A connected object, which is able to calculate its own position without using embedded elements specific for doing this. The connected object possesses a wireless receiver for receiving signals coming from a plurality of located terminals. The signals include location data for locating the located terminals. The connected object calculates a piece of geolocation information of its own position based on a plurality of location data coming from the various located terminals.
Claims9
A connected object which comprises:
- a wireless receiver, which is configured to receive signals originating from a plurality of located terminals, said signals comprising location data for locating said located terminals;
- a processor configured to:
- calculate a geolocation information item in respect of a position of the connected object on the basis of a plurality of the location data originating from different ones of the plurality of located terminals,
- determine a precision datum associated with the calculated geolocation information item, a value of this precision datum taking into account a number of occurrences of location data used for the calculation of the geolocation information item, and
- periodically activate and deactivate the wireless receiver and the calculation of the geolocation item, wherein a frequency of activating the wireless receiver evolves in a manner inversely proportional to the value of the precision datum;
- and
- an emitter, which is configured to emit the precision datum and the geolocation information item.
A method for geolocating a connected object furnished with a wireless receiver, wherein the method comprises:
- receiving by the object signals originating from a plurality of located terminals, said signals comprising location data for locating said located terminals,
- calculating within the object a geolocation information item in respect of a position of the object by using as input data at least one plurality of location data originating from different ones of the located terminals;
- calculating within the object a precision datum associated with the geolocation information item by taking into account a number of occurrences of the location data used for the calculation of the geolocation information item;
- the object periodically activating and deactivating the wireless receiver and the calculating of the geolocation item, wherein a frequency of activating the wireless receiver evolves in a manner inversely proportional to the value of the precision datum;
- the object periodically activating and deactivating the wireless receiver and the calculation of the geolocation item, wherein a frequency of activating the wireless receiver evolves in a manner inversely proportional to the value of the precision datum;
- and
- emitting by the connected object the geolocation information item and the precision datum.
A non-transitory computer-readable medium comprising a computer program product stored thereon comprising program code instructions for execution of a method of geolocating a connected object when said program is executed on a central unit of the connected object, wherein the program code instructions configure the connected object to:
- receive, by a wireless receiver of the connected object, signals originating from a plurality of located terminals, said signals comprising location data for locating said located terminals,
- calculate within the object a geolocation information item in respect of a position of the object by using as input data at least one plurality of location data originating from different ones of the located terminals;
- calculate a precision datum associated with the geolocation information item by taking into account a number of occurrences of the location data used for the calculation of the geolocation information item;
- periodically activate and deactivate the wireless receiver and the calculation of the geolocation item, wherein a frequency of activating the wireless receiver evolves in a manner inversely proportional to the value of the precision datum;
- and
- emit by the connected object the geolocation information item and of the precision datum.
A geolocation system, comprising:
- a plurality of located terminals;
- and
- at least one connected object comprising:
- a wireless receiver, which is configured to receive signals originating from the plurality of located terminals, said signals comprising location data for locating said located terminals;
- and
- a processor configured to:
- calculate a geolocation information item in respect of a position of the connected object on the basis of a plurality of the location data originating from different ones of the plurality of located terminals,
- determine a precision datum associated with the calculated geolocation information item, a value of this precision datum taking into account a number of occurrences of location data used for the calculation of the geolocation information item, and
- periodically activate and deactivate the wireless receiver and the calculation of the geolocation item, wherein a frequency of activating the wireless receiver evolves in a manner inversely proportional to the value of the precision datum;
- and
- an emitter, which is configured to emit the precision datum and the geolocation information item.
