Abstract: Systems (1) for remote data collection at an assembly of local sites (S1, S2, SN, SL) towards a central site (SC), comprising a central control and processing unit (6, 7), each local site (SC) comprising local data collection devices (D1, D2, DN, 10). In each local site (S1, S2, SN, SL), the local data collection devices (D1, D2, DN, 10) are arranged to identify and collect the data moving in a telecommunication line (L1, L2, LN, 9) and data emitted by external control and processing equipment (P1, P2) and comprise local memories (MR) to store these data. The central site (SC) is arranged to transfer via the telephone network (2) the stored data so as to be processed by the central control and processing unit (6, 7). Use for the collection and processing of data for statistical purpose, particularly in the field of pharmacological distribution.
