Abstract
The utility model discloses a terminal machine, which is suitable to the distributed selling computer systems of large and medium-sized shops and markets. The front face of an outer casing thereof is provided with an induction type touching keyboard, a display device, a magnetic card reader-writer, a miniature printer, and a buzzer. An inner circuit takes an SCM as a core, and a P1 port is connected with induction type touching keys; a serial interface is accessed to the terminal machine of a checker via a level changing circuit, and a P2 port is accessed to the magnetic card reader-writer via a signal processing circuit. A display device is accessed to the display device via a shift register and a drive circuit; data bus lines are accessed to the miniature printer via a data buffer and are directly accessed to a display circuit.
Description
The utility model relates to the terminating machine of the distributed computer system of selling goods.
The selling goods of the large and medium-sized market of China, gathering, financial statistics, merchandise sales trend analysis and prediction at present, business activities such as operating activity monitoring contact is mostly adopted intensive labor management, waste of manpower, financial resources.Even computer management is adopted in some markets, also be to be confined to main supvr and main business department handles computing to the main level of control and the data of business activity.But for the business activities in whole market (as cashier, shop-assistant's business activity and and other business departments between contact), also there is not the complete computer system of a cover comprehensively to manage and control, therefore, the needs that do not adapt to the extensive operating activity in market.
The utility model purpose provides a kind of intelligent shop-assistant's terminating machine that uses for the shop-assistant, be convenient to and cashier and market business department between business contact and automatic management.
The utility model is made up of single-chip microcomputer, keyboard, magnetic card read write line, mini-printer, display, and the housing front is provided with induction type touch keyboard, display, magnetic card read write line, mini-printer.The P of single-chip microcomputer in the interior circuit
1Mouth links to each other with the induction type membrane keyboard, and serial line interface links to each other P by level shifting circuit with cashier's terminating machine
2Mouth inserts the magnetic card read write line through signal processing circuit respectively; Insert display by shift register, current-limiting resistance, driving circuit, the data bus of single-chip microcomputer inserts mini-printer and inserts display circuit, single-chip microcomputer P by data buffer respectively
2Mouth links to each other with hummer through amplifier tube.The utility model also can adopt another kind of single-chip microcomputer, the P of single-chip microcomputer
0Mouth inserts external program memory and external expansion interface circuit respectively, the A mouth one tunnel of external expansion interface links to each other with mini-printer, display circuit is inserted on another road, and structural principle as hereinbefore for remainder (parts such as keyboard input, serial port, warning).
The distributed sales system in the utility model and whole market is used, and can realize automatic management and control to whole business contacts, improves the work efficiency of each business department, reduce labor intensity, prevent to falsely claim as one's own commodity, reduce the cash mistake, improve the sales force and the competitiveness in shop.The utlity model has the technological means advanced person, characteristics such as DATA DISTRIBUTION typing, its social benefit and economic benefit are obvious.
Accompanying drawing 1 is the utility model shape assumption diagram.
Accompanying drawing 2,3 is the utility model circuit theory diagrams.
Below in conjunction with accompanying drawing the utility model is further described, the utility model is the intelligent shop-assistant's terminating machine for shop-assistant's special configuration as the part of market distributed sales system.Central processing unit/local the central processing unit of distributed sales system hardware part is made up of PC/386 or other compatible, " floppy disk, 24 needle printers and communication interface etc. also can adopt workstation and somely do not form with the terminal of external memory comprising main frame, CRT, 20M or 40M hard disk, 5.Cashier's terminal can adopt two kinds of different hardware configurations.A kind of hardware mode can be made up of a PC or other compatible.Another kind of hardware mode can increase the RAM of an expansion in the structure of shop-assistant's terminal, CRT controller and monitor.The hardware configuration of intelligent shop-assistant's terminating machine of the present utility model is to do core members with single-chip microcomputer 1, P
1Mouth connects induction type membrane keyboard 2, and data bus links to each other with mini-printer by data buffer 10, and the serial port of single-chip microcomputer links to each other with cashier's terminal through level shifting circuit 3, and signal processing circuit 4 inserts magnetic card read write line 5, P
2Some corresponding function lines of mouth are the control line of printer, P
2Also by shift register 6, current-limiting resistance 7, driving circuit 8, access display 9, the data bus of single-chip microcomputer also inserts display circuit to mouth.Shop-assistant's intelligent terminal can read the shop-assistant by the magnetic card read write line and useful information such as identify from shop-assistant's magnetic card, clearly video data and order of light-emitting diode display, but the warning of hummer goods in transit false claiming and keypad sound response.The hardware configuration of intelligent shop-assistant's terminating machine of the present utility model, can also adopt with the single-chip microcomputer is core configuring external program storage in addition.Under this structure, the A mouth of single-chip microcomputer is made address data bus, and the least-significant byte address is latched by address latch by the output of A mouth; High 4 bit address are by the P of single-chip microcomputer
2The P2.0-2.3 of mouth directly delivers to the appropriate address of external program memory.This has just formed the addressing capability of external program memory.The A mouth of expansion interface is done data port, and a road direction mini-printer is sent 8 parallel bit data; Another road direction display is sent 7 sections fonts.B mouth and the C mouth PC by expansion interface selected in the position of display
0The position provides.With being connected of magnetic card read write line be C mouth PC3, PC4 with expansion interface.The expansion interface chip itself has the dynamic storage of 256 bytes, is used as to keep in directly to give the buffer zone of the character code or the data of shop-assistant's terminal by cashier's terminal.The utility model and whole distributed sales system are used, and are mainly used in code, quantity and necessary control order that the shop-assistant keys in the purchase of customer commodity; Show data and control command that the shop-assistant has keyed in, pay goods or refuse to pay the commodity prompting, calculate client's amount payable, from shop-assistant's magnetic card, read shop-assistant's sign and write shop-assistant's job record, print the commodity credit note respectively, the goods advice note paid by commodity and the shop-assistant sells daily sheet etc., receive and send relevant data from cashier's terminal to cashier's terminal.
