Abstract (en)

[origin: WO8002207A1] An electronic taximeter having a microcomputor (30) is adapted to store the current calibration factor of the meter and cause, upon initiation, display thereof on an electronic display (54). An electronic revolution counter (47) is adapted to progressively count and display the revolutions of a speedometer cable input to said meter such that calibration may be checked by driving the vehicle over a measured distance. Calibration may be readily altered merely by selecting different combinations of an 8-switch dual-in-line package (44). Other features include a real time digital clock (31) whereby total engaged time of the taxi during any particular period and the time of commencement and conclusion of a particular fare may be computed. Tariff rates may be altered by replacement of a single re-programmable and hence re-usable memory chip (33) and a miniature rechargeable battery (35) continuously trickle charge by the vehicle electrical supply ensures retention of all data including current operation mode data for up to about six months in the event of loss or failure of said supply. This latter feature is made possible by cyclically dumping, about every millisecond, current operation mode data into low power read/write memory circuits, wherein all other data is also stored, and powering said memory circuit by said battery in the event of said loss or failure.
