Description

Multi-functional taximeter

The utility model relates to a kind of taximeter, a kind of especially taximeter of multi-functional quaternity.

In recent years, along with the development need of taxi industry, the user has proposed stricter, more complicated requirement to fee register.On performance, require the failure rate of fee register low, antijamming capability is strong, on function, require to possess printed tickets, voice and report words, IC-card capital settlement and management in real time, with function such as computing machine communication.The fee register of usefulness in the market, though bigger improvement is arranged, its shortcoming is: 1. do not jump out original circle on line design, still adopt the version of CPU+ROM+RAM+ expansion I/O.The shortcoming of this version is that used wiring board area is big, multiple functional module can't be installed on one.In addition under identical working condition and condition of work, the failure rate height of fee register, poor anti jamming capability.2. structurally also do not have a kind of fee register all additional functional blocks to be integrated in one, particularly speech sound device all adopts circumscribed.Its shortcoming is that installation trouble, influence are attractive in appearance, has also reduced the interference free performance of fee register simultaneously.

The utility model purpose is for overcoming the prior art shortcoming, providing a kind of collection printed tickets, language to report words in real time.IC-card capital settlement and the multiple function of management, line construction is simple, the modular taximeter that antijamming capability is strong.

The technical solution of the utility model is to realize like this, it comprises shell, fee register main body, IC-card read write line, printer, characteristics be in fee register, be provided with the voice time receiver and with four one of fee register main body, IC-card read write line, printer, each uses a standalone module respectively, each module all includes an independent CPUs, the data communication of exchange data using serial, and communication structure adopts bus mode.

The utility model embodiment is described further in conjunction with the accompanying drawings.

Fig. 1 is the utility model block diagram;

Fig. 2 is a fee register main body wiring diagram.

By shown in Figure 1, be provided with the voice handie-talkie in the utility model fee register and connect into quaternity with valuation main body, IC-card read write line, printer, its each parts adopt a standalone module respectively, all be equipped with independent CPUs exchange data using serial data communication in the module, adopt bus mode.The fee register main body adopts the respectively control of different instruction collection realization to each module, on bus, add or remove a certain module, do not influence the realization of other functions, the fee register main body has been selected ultra-large microprocessor 89CXX family chip for use, complexity according to customer requirements is selected 89C52 or 89C55, include program storage in the chip, data-carrier store, three Timer, a serial port, 32 I/O mouths, by shown in Figure 2, it and external data memory 8583,24CXX, communications driver MAX232, display driver 74LS373 reach by LM393,74HCOO triode and resistance capacitance are formed resets and the power-fail interrupt circuit is connected.The concrete connection is explained as follows, 1,2 pin of 89CXX are connected to form clock circuit with 8583 6,5 pin respectively, 3,8 pin of 89CXX connect and compose memory circuit with 5,8 pin of 24CXX respectively, 8 output terminals 32～39 of 89CXX are connected with 8 input ends of two display driver 74LS373, and constitute the section display circuit of display circuit by 27,28 two ends, two 74LS373 of output control.

Connect 11,9 pin of 74LS07 respectively by 6 pin, 11 pin of 89CXX, 10 pin of 74LS07 meet connector J ₁, J ₂, J ₃4 pin, 8 pin of 74LS07 meet J ₁, J ₂2 pin and J ₃5 pin and 11 pin of MAX232,12 pin of MAX232 connect J respectively ₁3 pin and 74LS075 pin, J ₂3 pin be connected J with 3 pin of 74LS07 ₃6 pin connect 1 pin of 74LS07,6,4,2 pin of 74LS07 link to each other J with 10 pin of 89CXX ₃3 pin link to each other with 13 pin of 74LS07,12 pin of 74LS07 link to each other with 5 pin of 89CXX.Connector J ₁, J ₂, J ₃Be connected with speech sound device, printer, IC-card read write line respectively, this has just constituted the fee register main body and printer, speech sound device, IC-card read write line reach the circuit by MAX232 and the direct communication of computing machine.

Reset and the power-fail interrupt circuit is important component part of the utility model, specifically connect as followsly, 5 pin of LM393 connect resistance R ₂₇, R ₂₉, R ₂₉Another termination automobile storage battery positive source, R ₂₇Other end ground connection, the 6 pin connecting resistance R of LM393 ₂₆, R ₂₈, R ₂₆Another termination 5V, R ₂₈, R ₂₆Other end ground connection, 7 pin of LM393 connect 12 pin and the pull-up resistor R of 12 pin of 89CXX, 74HCOO respectively ₂₅, the 3 pin connecting resistance R of LM393 ₁₉, R ₂₂, R ₁₉The other end connect resistance R ₁₇, R ₁₈, R ₁₇Another termination 5V power supply, R ₁₈Other end ground connection.Resistance R ₂₂The other end connects 1 pin of LM393 respectively, 9 pin of 89CXX, 13 pin of 74HCOO and pull-up resistor R ₂₁, 74HCOO 11 pin connect 9,10 pin itself, 8 pin of 74HCOO connect diode cathode and resistance R ₂₄, diode cathode meets R ₂₃, R ₂₃The other end and R ₂₄The other end link to each other, and simultaneously and 2 pin of LM393, the e utmost point of triode 9013, electric capacity E5 and R20 connect, R ₂₀The other end connects 9013 the b utmost point and passes through capacitor C ₂₁Be connected with 26 pin of 89CXX.This circuit has and automatically resets and power-down protection can be monitored the variation of automobile storage battery voltage automatically.
