Abstract

The utility model relates to a combined probe and a read-write device of an intelligent card and a bar code with a non-contact type, being a control device in an automatic management system of channel ticket business with a closed type. Under the conditions that an RF card is used as a long-term measuring through ticket and a ticket used for printing bar codes is a petty ticket, the antenna of the read-write device of an original RF card is designed into an antenna with the shape of a rectangle or an ellipse or a circle. Between the double-layer glass at the laser window of the bar code, a same SCM and the circuit thereof and a software are used for processing the RF card and the bar code data. The combined probe and the read-write device which are designed in this way, has the ability of nondirectionally recognizing bar codes and read and write an RF card in a non-contact way at the same window.

Description

Contact type intelligent card and bar code combined probe and read write line

The utility model relates to a kind of control device

In the prior art in the world today, the existing memory function of high integration has the smart card of data processing function again concurrently, and is more more advanced as the IC-card of memory body than adopting integrated circuit in automatic monitoring system system.The core of smart card is a minimum one chip microcomputer, include: microprocessor (CPU), random-access memory (ram), erasable journey ROM (read-only memory) (EPROM) or E EPROM, hold in order to pack into into the application content that reaches the special permission of hair fastener unit for information about, therefore, also can be referred to as customer memory, memory capacity 2～6KB, also has an interface circuit, it is a single line, two-way, asynchronous, passage based on character, transfer rate is the 106K baud, existing smart card is that contact chip by being fitted on the card face is finished with extraneous the contact, card is inserted read write line, can be communicated with computer system, carry out online on-line operation; But using smart card in enclosed-channels such as sub. in the ticket management uses as the ticket of having the records of distance by the log, because flow of the people is big, per person wants plug-in card, cause read write line short-lived, for this reason, a kind of contact type intelligent card also is called the actual application that obtained of radio-frequency card (RF card), be characterized in being equipped with in the card radio-frequency antenna, antenna with read write line, within certain distance, transmit electronic information non-contactly, in some developed country's subway ticket managements, used, but RF card cost is more expensive, uncomfortable very big as the floating population, the big city that disposable use is higher, this just needs a kind of cheap ticket that can count and replenishes, and has provided small change that is printed with bar code and the ticket management method that becomes through ticket with the RF blocking in " automatic enclosed-channel bill management method " of our company's invention.But originally the identification of the read-write of the read write line of RF card and bar code is respectively to become system, is two kinds of equipment independently, and RF card and bar code need be placed on the antenna laser window on the different zones, just can finish data processing.In subway passenger ticket management system, crowd in the face of numerous different quality, use the RF card as monthly ticket and season ticket, use bar code as common single small incidental expenses ticket, if the passenger who requires to hold different tickets in by the process of automatically-controlled door on different zones the ticket checking meeting bring inconvenience and be chaotic.

Purpose of design of the present utility model is to make the identification of the read-write of RF card and bar code structurally integrated, makes on the same window on the same device of operating in of RF card and bar code and carries out, can noncontact, handle two kinds of data on the medium in no direction.

The following technical scheme of purpose of design of the present utility model realizes: with RF card Antenna Design is tours antenna, places in the abrasion-resistance glass and the gap between the filter glass of bar code laser window, becomes one on the structure; Read write line is with the data of same single-chip microcomputer and circuit and software processes RF card and two kinds of different medium of bar code; Make combined probe and read write line.

She Ji combined probe and read write line have on the same window non-contactly like this, discern the ability of bar code and read-write RF card in no direction, have reached the utility model purpose of design.

Below with reference to accompanying drawing the utility model is described in further detail: Fig. 1 a, b are the utility model combined probe knot synoptic diagram; Fig. 2 is the utility model read write line circuit theory calcspar.

With reference to Fig. 1, by bar code laser read window and the RF antenna 3 compound combined probes of forming, RF snap ring shape antenna 3 be shaped as rectangle, ellipse garden shape or garden shape, the number of turns is more than 1 circle, is bonded on the following concave edge of casing 1 with glue-line 6 around it.Be installed in the gap between abrasion-resistance glass 2 and the filter glass 4, do not block continuously, many, directionless pulse swashs.Light-beam generator 5 emitted laser bundles, and be connected with read write line 7 interfaces with combined probe with cable, be installed in jointly in the same casing 1.

With reference to Fig. 2, read write line 7 of the present utility model is by power supply 21, reset key (RESET) 22, single-chip microcomputer 23, bar code interface circuit 24, liquid crystal or light emitting diode status displays 25, hummer 26, power take off 27, scrambler 28, modulator 29, detuner 30, demoder 31 and high-frequency carrier signal generator 32 are formed; Modulator 29 is capacitive coupling with antenna 3, and detuner 30 is inductive coupling with antenna 3; Bar code interface circuit 24 is directly accepted the bar code recognition signal, and power take off 27 is sent out control signal and passed automatically-controlled door, to reach the purpose of Detection ﹠ Controling.

Read write line 7 circuit all adopt integrated circuit to form, and are equipped with microdevice, and compact conformation is equipped with well-designed software, serve as the control core with single-chip microcomputer 23, the entire circuit coordinate operation.Single-chip microcomputer 23 provides data, and encoded device 28 modulators 29 are delivered to RF antenna 3 and sent signal, finish the NE BY ENERGY TRANSFER to the RF card, sets up contact and data and writes; RF antenna 3 receives the data that the RF card is beamed back, and through detuner 30, sends into single-chip microcomputer 3 behind the demoder 31 and handles.High frequency signal generator 32 is given the high-frequency carrier signal of modulator 29, and making modulator signal take place for RF antenna 3 becomes possibility.After bar coded ticket is read in by the laser read device, send into single-chip microcomputer 23 by bar code interface circuit 24 and handle.The read-write back shows multiple real-time status by display 25, provides sound caution by hummer 6, handles and control automatically-controlled door continuously by power take off 27.

The utility model is reasonable in design through trial-production, evidence, is suitable for practicality, is equipment indispensable in the middle of the subway ticketing service automated management system.
