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
The present invention relates to fee register field, be specifically related to a kind of simple and convenient taximeter being applicable to deaf-mute and using.
Background technology
Taximeter adopts 89S51 single-chip microcomputer to be primary controller mostly, find range with Hall element, the basic function of fee register can be realized preferably, but because 51 single-chip data processing poweies are limited, make general fee register without language process function, like this, the physical disabilities in hearing promptly and accurately can not recognize the situation of concrete facticity, inconvenient this kind of people uses, and is easily cheated.
Summary of the invention
The present invention is intended to propose one to be convenient to
Technical program of the present invention lies in:
One is taximeter simply and easily, is made up of single-chip microcomputer, photoelectric velocity measurement circuit, keyboard control circuit, memory circuit and output circuit; Wherein, photoelectric velocity measurement circuit, keyboard control circuit, memory circuit and display circuit directly connect single-chip microcomputer, and output circuit is 16 LED, and described output circuit is also provided with a buzz circuit.
Preferably, described photoelectric velocity measurement circuit adopts intermittent type photoelectric sensor, and photoelectric sensor is groove structure, is placed on stationary shaft, and multiple anti-dazzling screen fixed equably by wheel, and it is just by light groove.
Or preferably, be also provided with a motor, this motor is connected with photoelectric sensor, driven by special bridge-type motor drive ic L298N.
More preferably, described bridge-type motor drive ic comprises 4 channel logic driving circuit motors.
Technique effect of the present invention is:
Present invention achieves motor simulation wheel, infrared electro tests the speed, numeral method mileage, time speed of a motor vehicle display, charging adjustment accesses to your password lock open function, achieve voice broadcast function, compared with similar fee register, design have easy to operate, energy consumption is little, the advantage such as functional, other functions can also be increased, have very high expansionary and explorative.
Accompanying drawing explanation
Fig. 1 is anatomical connectivity block diagram of the present invention.
