| Abstract: | The designing of taximeters is implemented with a FPGA chip and peripheral circuits in four modules of l00-meter pulse frequency,mileage calculation, evaluation,and nixie tube scanning and decoding. Besides,the model, unit price, flag-fall price, mileage, extra added values are modified. Results show that the meter adapts to different taxicabs in different regions. |
