Embodiment

The passenger vehicle intelligent charger that the utility model proposes is made up of the electronic circuit and the application program of shell and clamping device, microprocessor control.The taximeter shell and the device as shown in Figure 1, clamping device is clamped on passenger vehicle instrument panel or other position, makes things convenient for driver operation.The electronic circuit of microprocessor control is made up of number demonstration, keyboard, 51 series monolithics (microprocessor CPU), printing interface, power supply, hummer, storer, keyboard and display interface etc., as shown in Figure 2.

The principle of work of this passenger vehicle smart electronics charging device and the following (see figure 3) of the course of work:

General passenger vehicle has direct current 24V or 12V power supply.When supplying with, then behind electric resistance partial pressure, pass through two 7805 voltage stabilizing chips respectively, produce two road 5V DC voltage as direct current 24V power supply.One the road supplies with main circuit work, and external mini-printer is supplied with on another road.The display part is by seven charactron LED ₁～LED ₇With 5 pilot lamp D ₁～D ₅Form.Pilot lamp is used for showing the duty of taximeter.As the night/daytime pilot lamp, up/descending pilot lamp.Seven LED charactrons show date, ridership, statistics etc. on the order of classes or grades at school, employee's number, station period, admission fee, passenger vehicle.Keyboard is made up of numerical key, admission fee key and function key.Numerical key input date, order of classes or grades at school, employee's number etc.; The admission fee key is imported the admission fee and the luggage admission fee of each website; Function key have query key, printing/communication key, INC, DEC, the night/daytime key, luggage key, up/following line unit, switch key and acknowledgement key etc.Charging result can be by external mini-printer printout, also can be by RS232C and computing machine communication.Both can select by jumper wire device.

The demonstration of website, admission fee and patronage is by IC ₁, IC ₂, IC ₃, IC ₄, IC ₆Digital keys, admission fee key, luggage key, acknowledgement key and LED charactron are formed.Input to memory IC by keyboard ₁In, as determining admission fee key validity and the foundation that shows patronage on the car in real time.After the taximeter start powers on, microprocessor IC ₂By keyboard and display interface chip IC ₃, IC ₄Show date to the LED charactron, revise by keyboard, and behind the order of classes or grades at school of data operator's job number sign indicating number, charactron shows the car station number that it's 5 seconds past for prompting input passenger fare, charactron shows the ridership on the current passenger vehicle.Button is forbidden revising the admission fee function in addition, prevents from deliberately to revise admission fee.During the button input, charactron shows the content of input in real time, and hummer is sent out " toot " sound simultaneously, reminds the driver to finish input.Microprocessor IC ₂By judgement, and compare analysis, useless admission fee key was lost efficacy, in order to avoid maloperation with the website fare table to the car station number.Neutralize on the way to travel at bus driving and finish and to inquire about and to add up the charge situation, the project of inquiry has patronage on total toll amount, the passenger vehicle, each admission fee number in each admission fee number at every station, order of classes or grades at school, information and results such as luggage charge total value, order of classes or grades at school number, Yuan job number.Inquiry can be by date, order of classes or grades at school, the period of standing inquiry.Charge and patronage inquiry/statistics display circuit are by IC ₁, IC ₂, IC ₃, IC ₄, IC ₆Form with LED.Up, descending, daytime, night running indication by switch key, up/following line unit, the daytime/night key, IC ₁, IC ₂, IC ₃, IC ₄, IC ₆And D ₁～D ₅Form.

As the external mini-printer of this smart electronics charging device, then can be by printing/communication key with IC ₁, IC ₂In the charge result by printing communication interface chip IC ₅Output.Be connected with computing machine with RS232C serial communication line as this smart electronics charging device, then can be by printing/communication key with IC ₁In data pass through IC ₂, IC ₅Be input in the computing machine, can gather again, add up and inquire about data by computing machine and data base management system (DBMS) again, store and print.This smart electronics charging device can be discerned printing function or communication function automatically.C in the accompanying drawing 3 ₃, R ₆Form IC ₂Reset circuit, CRY ₁With C ₁, C ₂Form IC ₂Clock generation circuit.Buzzer circuit is by photoelectricity coupled circuit U ₉, D ₇, R ₁₉, R ₂₀With hummer U ₈Form.

The following (see figure 4) of application flows of this passenger vehicle smart electronics charging device:

After taximeter powered on, system carried out initialization, showed date, employee's number and the order of classes or grades at school of input in nearest a day.As identical, then press acknowledgement key and confirm; As inequality, then import by numerical key again, deposit data in memory IC after the input ₁In, and show the content of importing.Then button is scanned.As do not have key and press, then show the content of last time, and scan button once more; Press if any key, then press numerical key, admission fee key, function key three class execute key handling procedures.Numerical key is used to import date, employee's number and order of classes or grades at school; The admission fee key is respectively applied for input night admission fee, daytime admission fee and luggage admission fee according to the zone bit difference, determines the validity of admission fee key simultaneously intelligently according to the website of input and fare table, and admission fee deposits memory IC in after importing ₁In and show; Function key is used to carry out a certain function, as the night/daytime key, luggage key, up/following line unit, function switch key corresponding zone bit is set respectively, determine the running status of taximeter according to value of statistical indicant, query key can be inquired about by the sky, inquire about, inquires about by website by order of classes or grades at school, show Query Result simultaneously,: " ↑ " and " ↓ " key is used to show the content of an address and next address, printing/communication key is used for data are inputed to mini-printer or computing machine, and both functions can be carried out Intelligent Recognition by hardware and software.By the electronic circuit and the application software of this taximeter, can realize intelligent management and processing to data such as date, order of classes or grades at school, member's job number, admission fee, patronages.
