A PARKING METER SYSTEM

摘要

A system adapted for robust storage of parking meter information in a parking meter system is disclosed. The system comprises a plurality of cash boxes (106) and a corresponding plurality of parking meters (108), wherein the cash boxes (106) are periodically and substantially randomly, (i) mated with the corresponding plurality of parking meters (108) for a collection period, and (ii) subsequently collected from said corresponding plurality of parking meters (108). The system comprises parking meter storage means (102) for storing by each parking meter (108) (i) current information relating to a current collection period and (ii) historic information relating to a number of previous collection periods into each cash box (106) which is successively mated with said each parking meter (108), retrieval means (118) for retrieving all information carried by said each cash box (106) after removal of said each cash box (106) from a corresponding parking meter (108) and storage means (134) for storing said all information into a system data store, thereby to perform repetitive and thus robust storage of individual information records.
