Journey time measurement device for taxi - has sensors that respond to presence of passenger to activate counter circuit to provide direct measurement

摘要

A taxi has a normal meter that is mounted on or near the dashboard and is under the control of the taxi-driver. In addition there is a second meter or monitoring unit that is activated by the presence of a passenger. The activation is generated by sensors (3,6) built into the backrest and seat of the vehicle. These are activated by the weight of the passenger and result in signals to start a counter. At the end of the journey the count value is used in determining the fare. ADVANTAGE - Provides direct measurement of occupied time in taxi.
