COMMUNICATING SURVEY NAIL, TOPOGRAPHICAL GRID, DEVICE AND METHOD FOR RECORDING TOPOGRAPHY AND COMMUNICATING PORTABLE TERMINAL

摘要

The invention relates to a network of communicating survey nails (10) that each comprise an active radiofrequency identification beacon, comprising:a stand-alone electrical power source for powering a transmitter and a storage means;the storage means for storing a unique identifier and nail position data;the transmitter of a radiofrequency signal compliant with an RFID protocol comprising said unique identifier and said nail position data, the transmitter comprising an antenna.;The invention also relates to a device (30) for recording topography, which comprises at least three nails (10) and a georeferencing device (36) comprising:a first communication means (361) using an RFID protocol, for receiving the radiofrequency signal comprising the unique identifier and the position data of each nail; anda triangulation means (363) configured to calculate the position of the georeferencing device with respect to the position of the three nails.
