Abstract

The invention discloses a bus handheld ticket issuing machine which comprises a touch screen, a central processing unit and a printer. The touch screen is used for displaying station information and selecting a starting station and a stopping station. The central processing unit receives the selected starting station and the selected stopping station and transmits the selected starting station and the selected stopping station to the printer. The printer receives and prints the starting-stopping information transmitted by the central processing unit. The central processing unit and the printer are packaged in a handheld outer shell, the touch screen is located on a panel of the outer shell, and a printer outlet is formed in the outer shell. The printer comprises a paper rolling drum, a transmission belt, a printing selenium drum, a toner cartridge and a heating device, wherein printing paper is stored in the paper rolling drum, the transmission belt is used for conveying the printing paper, the back face of the printing paper is located on the transmission belt, the printing selenium drum is used for completing printing and located above the front face of the printing paper, the toner cartridge is used for providing toner for the printing selenium drum, the heating device is used for solidifying printed characters in a double-face heating mode, and the printing paper is clamped in the heating device. According to the bus handheld ticket issuing machine, due to the fact that station names are added in tickets, a steward can know whether passengers get off a bus at the right stations or not, and the passengers are prevented from taking the bus for a longer distance with less cost.

Description

A kind of bus hand-held ticket machine

Technical field

The present invention relates to a kind of bus hand-held ticket machine.

Background technology

Current have people's ticketing bus, is all generally by station charge.Ticket seller is according to rider's selling ticket of calling out the stops to valuate, but on ticket, do not show rider's bus loading zone and debarkation stop.Because rider is many, all motroists' of ticket seller's there is no telling station up and down.So there is the phenomenon of part rider understatement station with few friendship fare.

Summary of the invention

In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of bus hand-held ticket machine, by add name of station in ticket, make steward know whether rider arrives at a station and get off, avoided the expense of the underpaying phenomenons of sitting station more.

To achieve these goals, the technical solution used in the present invention is:

A kind of bus hand-held ticket machine, comprising:

Touch-screen, for display station dot information, and selects start-stop station;

Central processing unit, receives the start-stop station of selecting and is forwarded to printer;

Printer, receives start-stop station information printing that central processing unit forwards;

Wherein, described central processing unit and printer are packaged in hand-held outer case, touch-screen is positioned on housing face-plate, on shell, have outlet of printer, touch-screen is by Mt6301 chip drives, central processing unit is made up of 8086 chips, and selected start-stop station information is sent to central processing unit by the data line on touch-screen, then transfers to printer by central processing unit by parallel interface chip and complete printing;

Described printer comprises:

Store the chart drum of printer paper;

For transmitting the driving-belt of printer paper, the reverse side of printer paper is positioned on driving-belt;

Be used for the print wheel of printing, print wheel is positioned at prints recto top;

Be used to the powder box of print wheel ink supply;

And for printing the rear curing well heater of word, well heater is Double-side Heating, and printer paper is held on wherein.

The present invention also comprises code translator, and code translator is made up of 74LS138 chip, connects central processing unit, choose parallel interface chip through address bus, owing to there being the existence of code translator, being convenient to central processing unit and separately connecing other chip simultaneously, for the Function Extension of later ticket machine leaves sufficient space.

Compared with prior art, the invention has the beneficial effects as follows:

The present invention, by the ticketing of hand-held liquid crystal display, has volume little lightweight, and convenient operation, can change the existing people's of having ticketing pattern effectively.Underpay under the expense prerequisites of sitting station morely in change, can not affect ticket seller's ticketing speed.The technology that the present invention adopts Mt6301 chip and 8086 to combine, has reaction velocity fast,

The significant advantage that cost is low lays a solid foundation in actual for large-area applications in price.Owing to there being the existence of code translator 74LS138, being convenient to central processing unit and separately connecing other chip simultaneously, for the Function Extension of later ticket machine leaves sufficient space.

Embodiment

Describe embodiments of the present invention in detail below in conjunction with drawings and Examples.

Referring to Fig. 1, a kind of bus hand-held ticket machine, arranges touch-screen 2 at shell one side surface of the main frame 1 of hand-held, and shell bottom arranges prints outlet 3, and whole device volume is little, is convenient for carrying.

Referring to Fig. 2, on touch-screen 2, show all site information, then click the start-stop name of station of selecting rider, turn by control module processing, finally print by click, print the ticket at start-stop station by printing outlet 3.

Referring to Fig. 3, aspect concrete control, touch-screen 2 is by Mt6301 chip drives, and central processing unit 4 is made up of 8086 chips, and parallel interface chip 5 is made up of 8255A chip, and code translator 6 is made up of 74LS138 chip.Site information is by the data line DIN on touch-screen 2, data are sent to the data line D0～D7 of central processing unit 4, when central processing unit 4 receives after data, be transferred to again the data line D0～D7 of parallel interface chip 5 by its data line D0～D7, when parallel interface chip 5 receives after data, be sent to the data line D0～D7 of printer 3 by its A mouth data line, final control printed site information.

The program of control module is as follows:

Referring to Fig. 4, aspect print machinery, printer paper 12 is stored by chart drum 13.Station name of station prints to printer paper 12 by powder box 10 by print wheel 9.Printer paper 12 is driven by driving-belt 11, and printed station name of station is fixed on printer paper 12 by well heater 8.Ticket is by printing outlet 7 outputs.
