Abstract

The utility model provides a vehicle mounted automatic ticket sales machine belonging to the field of the automatic control, which comprises an automatic control circuit comprises a SCM circuit, an input keyboard, a display circuit and a communication interface and a minitype dot printer. By receiving the informational input of the destination station information and the purchasing denomination of the passenger by the input keyboard, the SCM circuit dispatches instruction after the treatment. Then the informational input is changed into Chinese character signal through the level conversion by the communication interface circuit, and a ticket with the identification of the name of the previous bus stop, the name of the next bus stop and the ticket price on the on the surface is printed out by controlling the minitype dot printer. The vehicle mounted automatic ticket sales machine of the utility model provides the equipment support for the remote cross-section public transport lines which carries out the use of ticket vending machines for booking the tickets, which is a supplementary of the existing IC card booking system.

Description

Automobile mounted automatic machine

Affiliated technical field

The utility model provides a kind of automobile mounted automatic machine, and particularly a kind of vehicle-mounted automatic machine that is used for public transit system belongs to automation field.

Background technology

The ticketing of long-range public transport does not also break away from artificial ticketing mechanism at present fully, particularly need public bus network by the interval section of striding ticketing, must a ticket seller carry out ticketing, brought many practical problemss like this: the ticket seller collects money not to ticket, less to ticket, individual passenger was leaked ticket when the passenger was crowded, even some passenger steals a ride, the section of striding is not bought one's ticket after normal time by bus, and these all are the things of the leader of each public transport company headache.

Summary of the invention

The purpose of this utility model be to provide a kind of simple in structure, cheap, install and can print the automobile mounted automatic machine that effectively take interval bill with car by the garage position.

Automobile mounted automatic machine provided by the utility model, form by automatic control circuit and output unit, its feature is: adopt mini-printer as output unit, automatic control circuit adopt single chip circuit that microprocessor and peripheral chip thereof constitute, input keyboard, display circuit, and communication interface form; The every station of driver, by the button that once " arrives at a station ", the single chip circuit record is also handled this signal, when the passenger need buy tickets, input keyboard is with passenger's vote buying volume input single chip circuit, after single-chip microcomputer is handled, send display circuit to show, confirm for the driver, scm software according to the denomination of the information of arriving at a station of driver input and affirmation through after calculating, the control mini-printer is effectively taken the interval with Chinese character printing from what our station played that certain station ends, by hand papercutter the bill of printing is downcut again, the passenger just can take smoothly to identify on the nominal value to have and get on the bus name of station and got off the ticket of name of station and denomination, and all passengers ride with this ticket, and the examination personnel check ticket when the passenger gets off; Scm software reads the state of toggle switch S5 when electrifying startup, be normal sequence station or by the reverse sequence station in decision; Single-chip microcomputer will write down the number of times of buying this denomination ticket simultaneously, and total ticket amount of money of selling; When bus is got back to master station and is come off duty, link to each other with the computing machine of master station by communicating circuit, the ticketing situation of this train number today is downloaded in the computing machine, for financial staff's processing; In addition, scm software is uploaded data function in addition, can accept name of station, interval, and the data such as admission fee of computing machine input.

Single chip circuit in the utility model is made up of microprocessor (U1), EEPROM (U2), Schmidt trigger (U9), watchdog circuit (U3).

Wherein, microprocessor (U1) is the control core, be responsible for control to peripheral components, Control Software also leaves in the FLASH of microprocessor, EEPROM (U2) uses as data storage, be used to preserve name of station, segment, admission fee and all single fares and buy number of times, operator password etc., watchdog circuit is used for that microprocessor (U1) resets when powering on and when program fleet, by force microprocessor (U1) internal processes is resetted.

Keyboard in the utility model is made up of 14 switches, 14 of microprocessor I/O mouths enter single chip circuit from single chip circuit, K0～K9 is a digit order number, S1 is " arriving at a station " information enter key, S2 is " denomination affirmation " enter key, S3 is " printing " run-out key, and S4 is " re-entering denomination " enter key, and S5 is " forward and reverse having the records of distance by the log " input toggle switch.

Display circuit is used to show denomination, confirm for the driver, display circuit is by two latchs (U7, U8), two charactron drivers (U5, U6), and the two-way display circuit formed of two charactrons (DS1, DS2), (AD0～AD7) output, its enable signal LE is by two I/O lines outputs in the microprocessor in the single chip circuit by the address wire of the microprocessor in the single chip circuit for the data-signal of latch (U7, U8).

Communicating circuit is made up of communication interface circuit (U4), be responsible for the Transistor-Transistor Logic level conversion of signals of microprocessor output is become the RS232 level signal, communicating circuit has a change-over switch, when switch is dialled when " printing ", (T1I, the R1O) of communication interface circuit (U4) is switched to the connecting line of printer, dial when " communication " when switch, (T1I, the R1O) of communication interface circuit (U4) connects the connecting line with the computing machine communication.

The output of output device and Data Update are the automatic control circuit control of core by single chip circuit.

Automobile mounted automatic machine provided by the utility model, Chinese character printing technology and single-chip microcomputer control technology have been used, arrive at a station and the interval paper ticket of effectively taking that passenger's actual denomination prints is the public transport one-way ticket so that bus is actual, also have receiving terminal name data, interval, admission fee simultaneously, download all individual event denominations and buy data functions such as number of times; This equipment efficiently solves following problem: guarantee effectively that 1, the ticket seller does not contact with ticket fee, 2, accomplishing really that nominal value shows effectively takes the interval, 3, the ticket inspector can show that effectively taking the interval prevents that the passenger from stealing a ride, leaking the ticket behavior according to nominal value, 4, passenger reimbursement has good grounds, and 5, the financial staff utilizes the ticketing volume of this train number of computing machine express statistic.
