Abstract
A system for programming and lighting electronic detonators (1) each having an identifier (IDdet) associated therewith, includes: a programming unit (20) arranged to determine the identifiers of the detonators (1) and to associate the detonators individually, in memory, with a lighting time delay (Tdet) in order to form a blasting pattern (PT); a blasting unit (10) arranged to recover the blasting pattern (PT) from the memory (280) of the programming unit (20), and to control a blasting sequence of the detonators according to the recovered blasting pattern; and the programming unit (20) includes: a passive RFID tag (28) provided with a chip (280) acting as a memory for storing the blasting pattern (PT), and a radiofrequency reader (27) arranged such as to read/write passive tags. A corresponding method is also described.
