IT1278880B1 - Portable charging recorder for the automatic recording of purchasing data for fuel for self-propelled vehicles - Google Patents

Abstract

Portable equipment of small size for recording data relating to the purchase of fuel for self-propelled vehicles from the distributors that is associated with a single vehicle whose identification code is permanently stored in a read only memory; the operations of the recorder are managed by a microprocessor that permanently stores in a non-erasable fiscal memory data relating to the purchases of fuel generated by the distributors themselves and transmitted through the connection components; the recording equipment is fitted with a security system that, to prevent abuse, prevents the reception of data and the corresponding delivery of fuel, if the recorder is carried away from the vehicle with which it is associated beyond a certain distance; alternatively, the security system permits the recording of purchasing data only for a limited time, defined by a timing circuit activated when the recorder is removed from the vehicle; in order to save space in the fiscal recording memory, some repetitive data concerning successive purchases of fuel, for example a code identifying the manager of the distributor is only stored in memory the first time it appears. <IMAGE>
