出租车又叫计程车,它收费的多少由计价器根据里程表的数据计算,里程表记录的是车辆行驶的路程.车辆行驶里程的纪录经历了从古代的记里鼓车到现代的里程表、速度表以及测速仪的过程.一、记里鼓车记里鼓车的原理是根据车轮的直径已知,车轮的圆周长便是恒定不变的.由此可以计算出每走一里路车轮要转多少圈,这个数也是恒定不变的.因此只要能够自动把车轮的转数积累下来,然后除以每一里路对应的转数就可以得到行驶的里程了.这样简单的原
Taxi is also called a taxi, how much it charges by the meter according to the odometer data, odometer records the distance traveled by the vehicle.Motor mileage record has gone from the ancient carriages to the modern odometer, Speedometer and speedometer process.A, remember the drum drum Kee drum drum principle is based on the diameter of the wheel is known, the circumference of the wheel is constant, which can be calculated for every one-way road wheels The number of turns, the number is constant, so as long as the wheel can automatically accumulate the number of revolutions, and then divided by the mileage for each mile on the road you can get mileage.
