Abstract

The invention relates to the field of taximeters, and particularly relates to a multifunctional taximeter which can be applied to a taxi. The multifunctional taximeter is composed of a single chip microcomputer AT89S52 control circuit, a for-hire lamp connected with the single chip microcomputer, an A44E hall sensor circuit, an AT24C02 storage circuit, a DS1302 clock circuit, an ISD2560 voice broadcasting circuit, a printing output circuit, a keyboard control circuit6, a 16-bit LED connected with a MAX7219 driving display circuit and a power circuit. the multifunctional taximeter can realize functions of mileage pricing and display, data storage and query, clock display, speeding reminding, voice broadcasting, bill printing and the like, is more convenient to use than certain taximeters on the market and complete in functions, can effectively prevent cheating of the driver and is good in system stability, and due to the speeding reminding function, the driver and a passenger can be reminded, the driver can be warned not be speeding, and a traffic accident can be prevented from happening.

Description

A kind of multi-functional fee register

Technical field

Invention relates to fee register field, is specifically related to a kind of multi-functional taxi fee register being applicable to taxi and using.

Background technology

Taximeter is the Special intelligent instrument of taxi operation charge, along with the development of electronic technology, the designing technique of taximeter is also in constantly progressive and improve, the development of domestic taximeter experienced by 4 stages, from traditional whole mechanical types be made up of mechanical components to half-electron formula (namely replacing some mechanical components and parts with electronic circuit) taximeter, again from the ic-type taximeter based on design of singlechip system up till now. whether taximeter charging is accurate, whether taxi driver exceeds the speed limit is the problem that passenger is concerned about most, and whether the management of fee register operation data is conveniently that taxi driver pays close attention to most.Therefore designing one can effectively prevent driver from practising fraud and overspeed prompting, and the multi-functional taxi fee register that conveniently can manage again operation data is particularly important.

Summary of the invention

The present invention is intended to propose one and effectively prevents driver from practising fraud and overspeed prompting, conveniently can manage again the multi-functional taxi fee register of operation data.

Technical program of the present invention lies in:

A kind of multi-functional fee register, 16 LED driving display circuit to connect by AT89S52 single board computer control circuit, empty car lamp, A44E Hall element circuit, AT24C02 memory circuit, DSl302 clock circuit, ISD2560 voice broadcast circuit, print output circuit, keyboard control circuit, MAX7219 and and power circuit form; Wherein, empty car lamp, A44E Hall element circuit, AT24C02 memory circuit, DSl302 clock circuit, ISD2560 voice broadcast circuit, print output circuit, keyboard control circuit, MAX7219 serial ports display circuit and power circuit all connect single-chip microcomputer.

Preferably, described Hall element is connected on automobile universal driving shaft.

Preferably, driving display is carried out in described AX7219 serial ports display circuit two panels MAX7219 cascade.

Preferably, described voice broadcast circuit adopts the ISD2560 chip that integrated level is higher, is integrated with microphone amplifier, automatic growth control clock, loudspeaker driving circuit, adopts+5 V Power supplies.

Or preferably, it is the TPmp-16 mini-printer that EPSON company produces that described print output circuit adopts, and micro-beating is connected by parallel interface with single-chip microcomputer.

Or preferably, the multi-functional fee register of described one is also provided with overspeed prompting circuit, is directly connected with single-chip microcomputer.

Technique effect of the present invention is:

Multi-functional taxi fee register of the present invention can realize mileage valuation and store with display, data and the function such as inquiry, clock display, overspeed prompting, voice broadcast and bill printing. use more convenient than some fee registers on market, function is more complete, also having and effectively prevent driver from practising fraud and the good advantage of system stability. overspeed prompting function wherein can remind driver and passenger, driver is warned not drive over the speed limit, with the generation avoided traffic accident.

Fig. 1 is the connection block diagram of a kind of multi-functional fee register of the present invention.

Embodiment

A kind of multi-functional fee register, 16 LED driving display circuit to connect by AT89S52 single board computer control circuit, empty car lamp, A44E Hall element circuit, AT24C02 memory circuit, DSl302 clock circuit, ISD2560 voice broadcast circuit, print output circuit, keyboard control circuit, MAX7219 and and power circuit form; Wherein, empty car lamp, A44E Hall element circuit, AT24C02 memory circuit, DSl302 clock circuit, ISD2560 voice broadcast circuit, print output circuit, keyboard control circuit, MAX7219 serial ports display circuit and power circuit all connect single-chip microcomputer.Wherein, Hall element is connected on automobile universal driving shaft; Driving display is carried out in AX7219 serial ports display circuit two panels MAX7219 cascade.Voice broadcast circuit adopts the ISD2560 chip that integrated level is higher, is integrated with microphone amplifier, automatic growth control clock, loudspeaker driving circuit, adopts+5 V Power supplies.It is the TPmp-16 mini-printer that EPSON company produces that print output circuit adopts, and micro-beating is connected by parallel interface with single-chip microcomputer, is also provided with overspeed prompting circuit, is directly connected with single-chip microcomputer.

Single-chip microcomputer collection also judges empty car lamp signal and distance detecting sensor signal, when taxi starts, microprocessor detect to Hall element pulse signal and carry out mileage calculation. when without passenger, single-chip microcomputer calls real-time chip DSl302 program and MAX7219 serial ports display driving software, carries out clock display with 4 LED; When empty car lamp break down, passenger loading time, ISD2560 voice broadcast circuit carries out voice broadcast 1 (this taxi is taken in welcome), by DSl302 acquisition time information, differentiate daytime/evening, then call AT24C02 program obtain daytime/unit price in evening and starting price, just start valuation and the information such as displaying time, mileage and the amount of money; When empty car lamp stamp, passenger getting off car time, carry out report 2 (to thanks and again take this taxi, please hand over amount of money $), and printed bill, single-chip microcomputer will operate data information memory in 24C02, after waiting for that taxi starts again, the information such as the single amount of money and mileage reset and reset, and complete and once valuate.

Some taxi driver send a passenger to obtain the more time more, they in the process of seing a visitor out to run at high speed the time of squeezing, and cause some traffic hazards, occur to prevent these accidents, by software detection travel speed in system program, when speed shows with red LED higher than during the top speed arranged, passenger can remind driver not drive over the speed limit, with the generation that avoids traffic accident after observing.
