PURPOSE:To shorten the turn-around time by evolving the master data onto a RAM together with the updating data obtained within a fixed period and retrieving and collating the vehicle plate information based on the pointers of lower four digits and the item number of the plate information. CONSTITUTION:The master data 1 is provided together with a table A2, a table B3, the updating data 4, a table C5, a table D6, a table E7, and the terminal data 8. Then the table B3 consisting of the pointers of lower four digits and the item number of the table A2 is retrieved for collation of the vehicle plate information obtained from the data 8. Furthermore the working table D6 or E7 is retrieved and the answer of hit or no-hit is returned. Thus the turn-around time is shortened. |
