Multifunctional taximeter based on single-chip microcomputer

Abstract

The invention discloses a multifunctional taximeter based on a single-chip microcomputer. The taximeter comprises an angle sensor, a Hall sensor, the single-chip microcomputer and a system power circuit. The angle sensor, a keyboard control circuit, a clock circuit and an encrypted circuit are connected with an input end of the single-chip microcomputer, an output end of the Hall sensor is connected with an input end of the encrypted circuit, the input end of the single-chip microcomputer is connected with a storage circuit, an output end of the single-chip microcomputer is connected with a voice broadcast circuit, an overspeed warning circuit, a note printing circuit and a driving displaying circuit, an output end of the driving displaying circuit is connected with an LED (light-emitting diode) light, and the system power circuit can supply power for the single-chip microcomputer, the angle sensor, the Hall sensor, the keyboard control circuit, the clock circuit, the storage circuit, the voice broadcast circuit, the overspeed warning circuit, the note printing circuit, the driving displaying circuit and the LED light. The multifunctional taximeter based on the single-chip microcomputer is simple in structure, reasonable in design, energy-saving and environmental-friendly, high in practicability, and is easy to popularize and use.

Description

technical field [0001] The invention relates to a taxi meter, in particular to a multifunctional taxi meter based on a single-chip microcomputer. Background technique [0002] Taxi meter is a product commonly used in our daily life. With the development of society, taxi is a very convenient and common means of transportation in people's life, but taxi meter is relatively backward. In the past, taxis used mechanical taximeters to calculate the mileage of the taxi with the gear ratio, and converted the fare from the mileage; due to the relatively large volume of the mechanical gear, the calculation was not very accurate, and It is easy to wear, and later the sensor method was adopted to receive the running information of the car by the sensor, thereby calculating the mileage and fare, but this method usually makes the interference signal also generate counting pulses, so it is not perfect, and the pricing is not accurate. The service life is short, and it cannot effectively p...

[0002] Taxi meters are commonly used products in our daily life. With the development of society, taxis are very convenient and common means of transportation in people's lives, but taxi meters are relatively backward

In the past, taxis used mechanical taximeters to calculate the mileage of the taxi with the gear ratio, and converted the fare from the mileage; due to the relatively large volume of the mechanical gear, the calculation was not very accurate, and It is easy to wear, and later the sensor method was adopted to receive the running information of the car by the sensor, thereby calculating the mileage and fare, but this method usually makes the interference signal also generate counting pulses, so it is not perfect, and the pricing is not accurate. The service life is short, and it cannot effectively prevent the driver from cheating and the function of speeding reminder
