3 is a flowchart illustrating a communication method of the IC card system, and is a flowchart illustrating a communication method between the console computer and the host computer of the IC card system. FIG. 3A shows the response request communication method, FIG. 3B shows the response reception communication method, FIG. 3C shows the communication method when there is no data for the response request, and FIG. 3D shows the case of no response to the response request or the response request. The communication method, and Figure 3E is a view for explaining ASCII characters of a signal and the meaning of the signal.

3A is a flowchart illustrating a communication method for requesting a response to a host of a computer. First, the computer sends a request signal (ENQ) to the host to request a response from the host (311). The host sends an acknowledgment (ACK) to the computer on the computer's request signal (312) to allow the computer to send a packet. The computer transmits the packet to the host in response to the host's recognition signal (313). The host completes communication by sending an acknowledgment signal 314 to the computer for packet transmission from the computer. However, if the host sends a non-aware signal (NAK) to the computer for packet transmission (315), the computer again sends the packet (316). In this case, if the host sends a recognition signal to the computer (317), the communication is completed, and if it sends a non-recognition signal (318), the communication error processing (319).

3B is a flowchart illustrating a communication method for receiving a response to a host of a computer. First, the computer sends a request 1 signal to the host for receiving a response from the host (321). The host transmits a packet to the computer according to the request 1 signal of the computer (322). The computer completes communication by sending a recognition signal (323) to the host for packet transmission from the host. However, if the computer sends an unrecognized signal to the host for packet transmission (324), the host again transmits the packet (325). At this time, when the computer sends a recognition signal to the host (326), the communication is completed, and if it sends a non-recognition signal again (327), communication error processing (328).

3C is a flowchart for explaining a communication method when there is no data for a response reception request from a computer. When the computer sends a request 1 signal for response response request to the host (331), if there is no data, the host sends a cancel (CANN) signal (332).

3D is a flowchart for explaining a communication method in the case of no response to a response request or a response reception request. When the computer repeatedly sends the request signal or the request 1 signal to the host for response request or response reception (341, 342), in the case of no response, error processing (343).

FIG. 3E is a table showing the ASCII characters (Octal, Hexa, Graphic) of the signals shown in the flowcharts of FIGS. 3A to 3D, that is, request, request 1, cancellation (CANN), recognition and non-recognition signals and their meanings. .

4 is a flowchart for explaining a communication method between the console computer and the host computer of the IC card system.

The input side of the console computer 43 of the IC card system waits (411) for checking whether there is data flowing from the card device 41 such as a card reader or from the host computer 45. The input side of the host 45 also waits (451,452) for checking whether there is data flowing from the computer 43 or from the queue 47.

The computer 43 continuously sends a request 1 signal for receiving a response to the data transmitted from the host 45 in the standby state (441), and sends the request signal to the host when data flows from the card device 41 in the standby state. Send (446) transmit data (447).

On the other hand, when the host 45 transmits a request signal for response request from the computer 43 in the standby state (446), it receives data from the computer (447) and performs the processing accordingly (454), and also queue ( If the data to be transmitted is generated (458) (47), the data is transmitted (443) to the computer 43.

Hereinafter, a description will be given of a method in which the computer 43 transmits data to the host 45 and a method in which the computer 43 receives data from the host 45.

First, a description will be given of how the computer 43 transmits data to the host 45. The computer 43 transmits a request signal to the host 45 when data flows from the card device 41 in the standby state 411 (446). The host 45 transmits the recognition signal or the non-recognition signal to the computer 43 for the request signal (453, 445). If the computer 43 receives the recognition signal, the computer 43 transmits the incoming data to the host (432, 447). The host 45 generates a FORC PROCESS 48 for processing the transmitted data (454), processes the data, and stores (456) or queues the processed result data in the database (49). (47). The data sent to the queue 47 is data to be transferred back to the computer 43 as a result of the processing of the data sent from the computer 43.

The following describes how the computer 43 receives data from the host 45, that is, how to transmit data generated by the host 45 to the computer 43.

When there is no data to be transmitted to the host 45 in the standby state (411), the computer 43 periodically sends a request 1 signal for receiving data from the host 45 to the host periodically (411). The host 45 continuously reads the queue 47 and continuously monitors whether there is data to be transmitted to the computer 43 (457). If the data is generated (458), the host 45 transmits the generated data to the computer 43. (443). At this time, the computer 43 sends a recognition signal or a non-recognition signal to the host 45 (431,442). If the recognition signal is transmitted, the transmission is completed. If the signal is a non-recognition signal, the host 45 sends data back to the computer 43. send.

On the other hand, the data of the queue 47 is generated as a result of processing the data 447 transmitted from the computer 43 and is different from the data 455 and data transmitted from the computer 43 to the computer 43. Regardless, it is stored in the database 49 and read out (for example, when the automatic door is forcibly opened or closed) in order to control the IC card system.
