device for interacting with a common taximeters by fjerroverforing berekningsenhet and seen to govern don at berekning of verdpris at such a meter in conjunction with a nemnd berekningsenhot

摘要

The invention relates to taximeter installations including mobile taximeter apparatus (2) coacting via radio (3, 4) with a central computer (1). Each taximeter (2) includes registers (15, 26) for collecting pulses relating to travelled distance and consumed time, the central computer (1) initiating periodic read-out (20, 21, 29, 30) of the register content, inter alia for fare price calculation. The central computer also sets a criterion frequency value, so that the pulses related to travelled distance are prevented by means of a circuit (9) from being stored in the register (15) when the frequency of said pulses falls below the criterion frequency, time pulses being stored in a register (26) when the criterion frequency is not attained by the travelled distance pulses.
