It relates to a communication analysis connection device for a financial automation device that can be analyzed using a protocol analyzer that can receive and analyze data using a RS-232 communication method. .

일반적으로 금융자동화기기는 금융서비스와 관련하여 신속하고 편리하게 은행직원의 근무시간에 구애받지 않고 현금 및 수표 입출금을 비롯한 여러 서비스를 무인으로 제공할 수 있도록 개발된 장치로서, 통장이나 신용카드의 인식과 비밀번호의 조회를 통해 금융거래가 가능하도록 이루어져 있으며, 현금 출금을 주거래기능으로 하는 현금출금기(Cash Dispenser), 현금(수표 포함)의 입출금을 주거래기능으로 하는 현금입출금기(Automated Teller Machine), 금융거래기능을 포함하여 여러 분야의 각종 콘텐츠를 제공하는 키오스크 등이 있다.In general, the automated teller machine is a device developed to provide a variety of services, including cash and check deposit and withdrawal, unattended, regardless of bank employee's working hours. Financial transactions are made possible through inquiry of password and password, Cash Dispenser with cash withdrawal function as main transaction function, Automated Teller Machine with financial withdrawal function with cash (with check) and financial transaction function There is a kiosk that provides a variety of content, including a variety of fields.

이러한 금융자동화기기는 도 1에 도시된 바와 같이, 각종 입출력수단들을 제어하여 전반적인 금융자동화기기의 작동을 제어하기 위한 메인콘트롤러(10), 이용자가 정보이용에 필요한 데이터를 입력하기 위한 키입력수단(11), 신분확인 및 거래계좌 확인을 위한 카드의 인입 및 인출을 제어하는 통장처리수단(12)과 카드처리수단(13) , 사용자가 요청한 현금을 입출금하는 현금입출금수단(14), 수표를 입출금하는 수표입출금수단(15), 거래결과를 명세표에 인쇄하여 출력하는 명세표인쇄모 듈(16), 이용자에 의한 요청결과를 화면으로 출력하여 제공하는 디스플레이수단(17), 금융기관의 호스트컴퓨터와 온라인 통신을 통해 금융거래를 수행할 수 있도록 하는 통신모듈(18) 등과 같이 각종 제어장치와 구동장치로 이루어져 있다. As shown in FIG. 1, the automatic teller machine includes a main controller 10 for controlling various input / output means to control the overall operation of the automated teller machine, and key input means for a user to input data necessary for using information. 11), the passbook processing means 12 and card processing means 13 for controlling the entry and withdrawal of the card for identification and transaction account confirmation, the cash withdrawal means 14 for depositing and withdrawing cash requested by the user, the deposit and withdrawal of checks Check and withdrawal means (15), a statement printing module (16) for printing and outputting a transaction result on a statement table, a display means (17) for outputting and providing a request result by a user on a screen, a host computer of a financial institution and online It consists of various control devices and driving devices such as a communication module 18 to perform financial transactions through communication.

특히 메인 콘트롤러(10)의 통신모듈(18)은 각 은행들에 구비되어 금융거래에 관련된 모든 정보가 저장되고 아울러 모든 거래가 실제로 실행되는 해당 금융기관의 호스트컴퓨터에 접속하여 금융거래를 가능하게 하고 있다.In particular, the communication module 18 of the main controller 10 is provided in each bank to store all the information related to the financial transaction and to access the host computer of the financial institution where all the transactions are actually executed to enable the financial transaction. .

그런데 금융기관마다 서로 다른 방식의 통신사양을 사용하고 있음에 따라 금융자동화기기에 장착되는 통신모듈(18)도 납품할 금융기관의 통신사양에 맞추어 장착하여야 한다. 때문에 생산과정중에 금융자동화기기의 통신기능에 대한 성능시험을 하기 위해서는 해당 금융자동화기기에 장착된 통신모듈과 동일한 통신방식을 적용한 프로토콜 분석기를 연결하여야 하므로 프로토콜 분석기 자체의 기능은 동일하더라도 단순히 통신방식이 상이함에 따라 별도의 프로토콜 분석기를 구비하여야 하는 문제점이 있었다.However, since different financial institutions use different types of communication specifications, the communication module 18 mounted on the automated teller machine must also be mounted in accordance with the communication specifications of the financial institution to be delivered. Therefore, in order to perform the performance test on the communication function of the automated teller machine during the production process, it is necessary to connect a protocol analyzer applying the same communication method as the communication module installed on the automated teller machine. As there was a difference, there was a problem of having a separate protocol analyzer.

본 발명은 상기한 사정을 감안하여 발명한 것으로, RS-422방식을 외부기기와의 통신사양으로 채택하고 있는 금융자동화기기를 프로토콜 분석기로 통신 문제에 대한 원인 및 분석을 함에 있어서 통상 널리 사용되고 있는 RS-232방식을 데이터 입출력 방식으로 채택하고 있는 프로토콜 분석기에서 분석할 수 있도록 RS-422방식 신호를 RS-232방식 신호로 변환할 수 있도록 된 금융자동화기기의 통신분석용 접속 장치를 제공하고자 함에 발명의 목적이 있다.The present invention has been invented in view of the above circumstances, and RS which is widely used in the cause and analysis of communication problems with a protocol analyzer using a financial automation device adopting RS-422 as a communication specification with an external device. The present invention is to provide a communication analysis connection device for an automated teller machine that can convert an RS-422 signal into an RS-232 signal for analysis by a protocol analyzer adopting the -232 method as a data input / output method. There is a purpose.

상기한 목적을 실현하기 위한 본 발명은, 금융자동화기기에 구비된 통신모듈의 RS-422출력포트에 접속되는 RS-422접속 컨넥터, 상기 RS-422접속 컨넥터에 연결되어 RS-422방식 신호를 TTL레벨로 변환하는 RS-422/TTL변환기, 상기 RS-422/TTL변환기에 연결되어 TTL레벨의 신호를 RS-232방식 신호로 변환하는 TTL/RS-232변환기, 일단이 상기 TTL/RS-232변환기에 연결되어 프로토콜 분석기에 접속될 수 있도록 된 RS-232접속 컨넥터를 포함하여 이루어져 있다.The present invention for realizing the above object, TTL is connected to the RS-422 connector, the RS-422 connection connector is connected to the RS-422 output port of the communication module provided in the automated teller machine TTL signal RS-422 / TTL converter for level conversion, TTL / RS-232 converter connected to the RS-422 / TTL converter for converting TTL level signal into RS-232 signal, one end of the TTL / RS-232 converter It includes an RS-232 connector that can be connected to the protocol analyzer.

이하 본 발명의 바람직한 일실시예에 대한 구성 및 작용을 예시도면에 의거하여 상세히 설명한다.Hereinafter, the configuration and operation of the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 일실시예에 따른 접속장치의 구성도를 나타낸다.2 is a block diagram of a connection device according to an embodiment of the present invention.

첨부도면에 도시된 바와 같이, 접속장치의 일단에는 금융자동화기기에 구비된 통신모듈의 RS-422출력포트에 접속하기 위한 RS-422접속 컨넥터(21)가 구비된다.As shown in the accompanying drawings, one end of the connection device is provided with an RS-422 connection connector 21 for connecting to the RS-422 output port of the communication module provided in the automated teller machine.

상기 RS-422접속 컨넥터(21)는 직렬통신 접속에 사용되는 컨넥터로 통상 9핀 컨넥터를 채용하며, 그중 2번핀에 RXD+ 신호선, 3번핀에 TXD+ 신호선, 7번핀에 RXD- 신호선, 8번핀에 TXD- 신호선, 그리고 5번핀에 GND선을 할당하여 사용한다. The RS-422 connection connector 21 adopts a 9-pin connector as a connector used for serial communication connection, of which RXD + signal line is pin 2, TXD + signal line is pin 3, RXD- signal line is pin 8, TXD is pin 8 -Assign GND line to signal line and pin 5.

일반적으로 병렬 통신 방식은 통신거리의 제한성, 구현상의 기술적인 어류움 과 비용이 너무 비싸다는 문제가 있어 어플리케이션 자체가 고속의 통신속도를 필요로 하지 않는 컴퓨터에서는 직렬통신을 많이 이용한다.In general, the parallel communication method has a problem in that the communication distance is limited, the technical clutter in implementation, and the cost is too high. Therefore, serial communication is frequently used in computers where the application itself does not require a high communication speed.

직렬통신의 대표적인 것으로, 모뎀, LAN, RS-232, RS-422 방식 등이 있으며, 컴퓨터와 단말 장치 사이에 직렬 통신 방식으로 데이터를 주고 받도록 하는 방법을 표준화한 통신 규격의 하나인 RS-422 방식은 직렬 통신 규격으로 이미 채택하여 사용 중이던 RS-232C의 제약을 극복하여 보다 고속 전송을 할 수 있고 전송 거리도 늘리기 위하여 1976년 미국 EIA(미국 전자공업회)에서 규정한 표준이다. 데이터 통신 최대 속도는 10Mk baud이고 최대 케이블 길이는 1.54km까지 가능하도록 되어 있다.Typical examples of serial communication include modem, LAN, RS-232, and RS-422 methods, and RS-422 is a standardized communication standard that allows data to be transmitted and received between a computer and a terminal device through serial communication. Is a standard defined by the US EIA in 1976 to overcome the limitations of RS-232C, which has already been adopted and used as a serial communication standard, to enable higher speed transmission and to increase transmission distance. The maximum data communication speed is 10Mk baud and the maximum cable length is up to 1.54km.

이와 같은 RS-422접속 컨넥터(21)에는 케이블을 통하여 RS-422/TTL변환기(22)가 연결된다. RS-422/TTL변환기(22)는 리시버(22A)와 드라이버(22B)가 구비되어, 상기 RS-422접속 컨넥터(21)측의 RXD+ 신호선과 RXD- 신호선이 리시버(22A)의 입력단으로 연결되고, 상기 RS-422접속 컨넥터(21)측의 TXD+ 신호선과 TXD- 신호선이 드라이버(22B)의 출력단으로 연결된다.The RS-422 / TTL converter 22 is connected to the RS-422 connector 21 through a cable. The RS-422 / TTL converter 22 is provided with a receiver 22A and a driver 22B, and an RXD + signal line and an RXD- signal line on the RS-422 connection connector 21 side are connected to an input terminal of the receiver 22A. The TXD + signal line and the TXD- signal line of the RS-422 connection connector 21 are connected to the output terminal of the driver 22B.

그리하여 RS-422/TTL변환기(22)중 리시버(22A)는 RS-422신호를 받아 TTL신호로 변환한 후 후단으로 전송하는 한편, 후단으로부터는 TTL신호를 받아 RS-422신호로 변환한 후 RS-422접속 컨넥터(21)측으로 전송하는 작용을 한다. 여기서 TTL신호는 예컨대 ±12V의 전압을 갖는 신호로 이루어진다.Thus, the receiver 22A of the RS-422 / TTL converter 22 receives the RS-422 signal, converts it into a TTL signal, and transmits the signal to the rear stage, while receiving the TTL signal from the rear stage, converts the RS-422 signal to RS. -422 Transmits to the connector 21 side. Here, the TTL signal consists of a signal having a voltage of, for example, ± 12V.

본 발명의 실시예에서는 RS-422/TTL변환기(22)로써 MC34050 를 채용하였다.In the embodiment of the present invention, the MC34050 is employed as the RS-422 / TTL converter 22.

한편, RS-422/TTL변환기(22)에 연결되는 TTL/RS-232변환기(24)는 RS-422/TTL 변환기(22)로부터 전송받는 TTL레벨의 신호를 RS-232형식의 신호로 변환하여 RS-232접속 컨넥터(26)로 전송함과 아울러 RS-232접속 컨넥터(26)로부터 전송받는 RS-232형식의 신호를 TTL레벨의 신호로 변환하여 RS-422/TTL변환기(22)로 전송하는 작용을 한다.Meanwhile, the TTL / RS-232 converter 24 connected to the RS-422 / TTL converter 22 converts the TTL level signal received from the RS-422 / TTL converter 22 into an RS-232 type signal. In addition to transmitting to the RS-232 connector 26, the RS-232 format signal received from the RS-232 connector 26 is converted into a TTL level signal and transmitted to the RS-422 / TTL converter 22. It works.

본 발명의 실시예에서는 TTL/RS-232변환기(24)로써 DS232 를 채용하였다.In the embodiment of the present invention, DS232 is employed as the TTL / RS-232 converter 24.

RS-232접속 컨넥터(26)는 직렬통신 접속에 사용되는 컨넥터로 통상 9핀 컨넥터를 채용하며, 그중 2번핀에 RXD 신호선, 3번핀에 TXD 신호선, 그리고 5번핀에 GND선을 할당하여 사용한다.The RS-232 connector 26 is a connector used for serial communication connection, and generally employs a 9-pin connector. Among them, an RXD signal line is assigned to pin 2, a TXD signal line to pin 3, and a GND line is assigned to pin 5.

상기와 같이 RS-422접속 컨넥터(21)로 입력되는 RS-422신호는 RS-422/TTL변환기(22)와 TTL/RS-232변환기(24)를 거쳐 RS-232접속 컨넥터(26)로 전송되면서 RS-232형식의 신호로 변환되어지는바, RS-422신호선과 RS232는 별차이가 없지만 RS-422신호선은 물리적으로 하나의 신호선에 두 개의 라인이 필요하며, 도시된 바와 같이 신호선이 + 와 - 로써 구분되어 있다. 즉, 예를 들면 RS-232의 TXD 신호선이 RS-422에서는 TXD+와 TXD-로 나누어진다. As described above, the RS-422 signal input to the RS-422 connection connector 21 is transmitted to the RS-232 connection connector 26 through the RS-422 / TTL converter 22 and the TTL / RS-232 converter 24. The RS-422 signal line and RS232 are not different, but RS-422 signal line physically needs two lines in one signal line, as shown in the figure. Are separated by-. That is, for example, the TXD signal line of RS-232 is divided into TXD + and TXD- in RS-422.
