Simple convenient taximeter

Abstract

The invention relates to the field of taximeters, in particular to a simple convenient taximeter that is applicable to deaf-mute people. The simple convenient taximeter comprises a single chip microcomputer, a photoelectric speed-measuring circuit, a keyboard control circuit, a storage circuit and an output circuit, wherein the photoelectric speed-measuring circuit, the keyboard control circuit, the storage circuit and a display circuit are directly connected with the single chip microcomputer, the output circuit is a 16-digit light emitting diode (LED), and the output circuit is provided with a buzzing circuit. By means of the simple convenient taximeter, wheel motor simulation, infrared photoelectric speed measuring, nixie tube mileage displaying and time and taxi speed displaying can be achieved, a coded lock starting function is achieved on charging adjustment, and a voice reporting function is achieved; compared with similar taximeters, the simple convenient taximeter has the advantages of convenient operation, small energy consumption, good performances and the like; other functions can be added, and the development is high.

Description

technical field [0001] The invention relates to the field of taximeters, in particular to a simple and convenient taximeter suitable for deaf-mute people. Background technique [0002] Most taximeters use 89S51 single-chip microcomputer as the main controller, and use Hall sensors to measure distances, which can better realize the basic functions of the taximeter. However, due to the limited data processing capability of the 51 singlechip, the general taximeter has no voice processing function. , the disabled people in the hearing aspect can't understand the specific and real situation in time and accurately, it is inconvenient for such people to use, and it is easy to be deceived. Contents of the invention [0003] The present invention aims to propose a convenient [0004] Technical scheme of the present invention is: [0005] A simple and convenient taxi meter is composed of single-chip microcomputer, photoelectric speed measuring circuit, keyboard control circuit, st...
