Fremgangsmåte og anordning for å lagre transaksjonsdata

摘要

The transaction data are acquired, treated and stored by a processing device arranged in the immediate proximity of measurement instruments, which processing device includes a control processor (H), and a storage module (S). The data are stored on non-volatile and redundant media (3,5) and under the supervision of a supervisory element (5) (possibly included within the control processor). Requests to be executed are transmitted thereto by the control processor (H) by way of a transmission path (L), and a buffer memory (8). The data involved in these requests are written and read on the storage media (3,5) via a backed-up memory (6). Permanent checks are made to verify the quality and fidelity of all internal transfers and also to back up the data in the event of an anomaly in the power supply. The safeguarded data in memory can be read upon an outside request. Application to the storage of values measured in particular by authorised apparatus for measuring volumes of liquids or solids.
