(Operation of network system 100)
Next, the operation of the network system 100 will be described.
FIG. 4 is a flowchart showing network connection confirmation processing executed in the sales data processing apparatus 1. In the network connection confirmation process, when the sales data processing apparatus 1 is initially installed by a service person, it is confirmed whether or not the communication environment of the sales data processing apparatus 1 is an environment in which data transmission / reception with the information center server 2 is possible. It is a process for performing. The network connection confirmation process is executed in cooperation with the CPU 10 and the processing program 141 stored in the storage unit 14 when the input unit 11 instructs execution of the network connection confirmation process.

First, the CPU 10 reads the screen display information stored in the storage unit 14 and instructs the display unit 12 to display a display signal based on the read screen display information, whereby the connection confirmation menu screen is displayed on the display unit 12. (Step S1). In the present embodiment, the connection confirmation menu includes “1. Connection confirmation”, “2. Port opening time confirmation (manual)”, and “3. Port opening time confirmation (batch processing)”. By inputting the number, a desired connection confirmation menu can be selected.
When “1. Connection confirmation” is selected, a connection confirmation process (see FIG. 5) is executed, confirmation of the link up state with the hub H, confirmation of whether or not communication connection with the information center server 2 is possible, and the like. Is done.
When “2. Confirm port opening time (manual)” is selected, port opening time confirmation processing A (see FIG. 6) is executed, and the communication port used for communication with the information center server 2 in the router R is selected. A manual check of the opening time is performed.
When “3. Port open time confirmation (batch process)” is selected, port open time confirmation process B (see FIG. 11) is executed, and the communication port used for communication with the information center server 2 in the router R Automatic confirmation of the opening time of.

  Next, it is determined whether or not “1. Confirm connection” is selected by the input unit 11 (step S2). If it is determined that “1. Confirm connection” is selected (step S2; YES), a connection confirmation process is executed (step S3).

  FIG. 5 is a flowchart showing a connection confirmation process executed in the sales data processing apparatus 1. The connection confirmation process is executed in cooperation with the CPU 10 and the processing program 141 stored in the storage unit 14.

First, it is confirmed whether or not the hub H is in a link-up state (communicable state) (step S101). As a result of the confirmation, if it is determined that the hub H is in a link-up state (step S102; YES), a confirmation packet is transmitted to the Ping server 3 by the communication unit 15 (step S103).
In step S103, a confirmation packet (ICMP packet; echo request) by the Ping command is created and transmitted to the Ping server 3, and a response request is made. When the confirmation packet is received, the ping server 3 immediately transmits an echo reply to the sales data processing apparatus 1. If the sales data processing apparatus 1 can normally receive a response from the Ping server 3, it can be confirmed that the line of the communication network N is normal and communication connection with an external apparatus is possible via the communication network N. In the sales data processing apparatus 1, the time from the confirmation packet transmission to the response reception is counted by the internal clock by the CPU 10 and stored in the RAM 13.

Next, it is determined whether or not a response is normally received from the Ping server 3 in the communication unit 15 (step S104). If it is determined that a response is normally received from the Ping server 3 (step S104; YES), communication is performed. The confirmation packet is transmitted to the information center server 2 by the unit 15 (step S105).
In step S105, a confirmation packet by the Ping command is created in the communication unit 15, and the confirmation packet is obtained by encrypted communication by tunneling between the encryption device of the communication unit 15 and the encryption device of the communication unit 25 of the information center server 2. Sent. When the communication unit 25 of the information center server 2 receives the confirmation packet, a response is immediately created and transmitted to the sales data processing apparatus 1 (steps T5 and T6 in FIG. 13). If the sales data processing apparatus 1 can normally receive a response from the information center server 2, it can be confirmed that communication connection with the information center server 2 is possible. In the sales data processing apparatus 1, the time from the confirmation packet transmission to the response reception is counted by the internal clock by the CPU 10 and stored in the RAM 13.

  When a predetermined time elapses after the transmission of the confirmation packet, output data of a connection confirmation result is created and output by the printing unit 16 or the like (step S106), and the connection confirmation process ends. Specifically, the connection confirmation result is the response time from when the confirmation packet is transmitted to the Ping server 3 until the response is received, and the communication result with the information center server 2 (the confirmation packet is transmitted to the information center server 2). If an error occurs during the response time from when the response is received, the error content and the like are printed out on a sheet such as a receipt by the printing unit 16. Alternatively, the connection confirmation result is displayed on the display unit 12. Alternatively, the sound is output by the sound output unit 19. Note that it is possible to set in advance by the user's operation of the input unit 11 which method is used to output the connection confirmation result.

  On the other hand, if it is determined in step S102 that it is not in a link-up state with the hub H (step S102; NO), or if it is determined in step S104 that a response has not been normally received from the Ping server 3 (step S104). NO), a connection confirmation result indicating that the line is abnormal is output (step S107), and the connection confirmation process ends.

  Returning to FIG. 4, if it is determined in step S2 that “1. Confirm connection” is not selected (step S2: N), “2. Confirm port open time (manual)” is selected from the connection confirmation menu screen. It is determined whether or not (step S4). When it is determined that “2. Check port opening time (manual)” is selected from the connection confirmation menu screen (step S4; YES), port opening time confirmation processing A is executed (step S5).

Here, as described above, the information center server 2 transmits a response to the sales data processing device 1 immediately after receiving the confirmation packet transmitted in the connection confirmation processing. However, when data transmission / reception between the settlement terminal 5 and the settlement server 4 is relayed by the sales data processing device 1 and the information center server 2, information is transmitted only for the communication time between the information center server 2 and the settlement server 4. It takes time to respond from the center server 2. Therefore, even if there is no problem in the connection confirmation processing, in actual operation, the communication port with the information center server 2 is closed by the security setting of the router R before the response is returned from the information center server 2. As a result, a communication error may occur.
Therefore, in this embodiment, in addition to the conventional “1. connection confirmation”, connection confirmation menus of “2. port opening time confirmation (manual)” and “3. port opening time confirmation (batch processing)” are provided. ing.
The port opening time confirmation processing A or the port opening time confirmation processing B executed by selecting “2. Port opening time confirmation (manual)” or “3. Port opening time confirmation (batch processing)” is the information center server 2, a response waiting time (referred to as a response WAIT time) is specified step by step manually or automatically, and a response message from the information center server 2 is received by the communication unit 15. This is a process for outputting a response result. The port opening time confirmation process A or the port opening time confirmation process B confirms the opening time of the communication port with the information center server 2 in the router R, and checks whether the communication environment that can be adapted to the actual operation is prepared. be able to.

  FIG. 6 is a flowchart showing the port opening time confirmation process A executed in the sales data processing apparatus 1. The port opening time confirmation process A is executed in cooperation with the CPU 10 and the processing program 141 stored in the storage unit 14.

First, the CPU 10 reads the screen display information stored in the storage unit 14 and instructs the display unit 12 to display a display signal based on the read screen display information, whereby the response WAIT time input screen 121 is displayed on the display unit 12. (Step S201).
FIG. 7 shows an example of the response WAIT time input screen 121. As shown in FIG. 7, the response WAIT time input screen 121 displays a response WAIT time input field 121a and an “end” key for instructing the end of the process.

  Next, it is determined whether or not the end key is pressed by the input unit 11 (step S202). If it is determined by the input unit 11 that the end key has not been pressed (step S202; NO), it is determined whether or not the response WAIT time is input from the response WAIT time input field 121a by the input unit 11 (step S203). ). If it is determined by the input unit 11 that the response WAIT time has been input from the response WAIT time input field 121a (step S203; YES), a response WAIT time designation request message D1 is created based on the input response WAIT time. (Step S204).

  FIG. 8 is a diagram illustrating an example of the data structure of the response WAIT time designation request message D1. The response WAIT time designation request message D1 is a message that requests the information center server 2 to transmit a response message after waiting for the response WAIT time. As shown in FIG. 8, the response WAIT time designation request message D1 includes a “message common header portion” and a “data portion”. Predetermined header information such as a transmission source IP address, a destination IP address, a port number, and the like is stored in the message common header portion. The data part stores a command indicating that the message to be transmitted this time is a response WAIT time designation request message, and a numerical value indicating the response WAIT designation time (seconds). As the response WAIT designated time (seconds), the time input from the response WAIT time input field 121a by the input unit 11 is stored.

  Next, a response WAIT time designation request message D1 is transmitted from the communication unit 15 to the information center server 2 (step S205). Further, reception of a response WAIT time designation response message D2 (see FIG. 9) from the information center server 2 is waited until a predetermined time (response WAIT time + α) corresponding to the response WAIT time input in step S203 has elapsed. (Step S206).

  FIG. 9 is a diagram illustrating an example of a data structure of the response WAIT time designation response message D2. As shown in FIG. 9, the response WAIT time designation response message D2 is composed of a “message common header part” and a “data part”. Predetermined header information such as a transmission source IP address, a destination IP address, a port number, and the like is stored in the message common header portion. The data portion includes a command indicating that the message to be transmitted this time is a response WAIT time designation response message, a status indicating the state of the information center server 2, and a response WAIT time (waiting time (seconds) in the information center server 2) Is stored.

  When a predetermined time has elapsed since the response WAIT time designation request message D1 has been transmitted, output data of a response result indicating whether or not the response WAIT time designation response message D2 has been received by the communication unit 15 is created, and the printing unit 16 or the like. (Step S207).

  FIG. 10 shows an example of the output of the response result in step S207. FIG. 10 shows an output example when the response result is printed out on the receipt paper by the printing unit 16. As shown in FIG. 10, the response result output in step S207 includes the response WAIT time (seconds) and its response WAIT time, such as “response WAIT time: 1 OK” and “waiting time: 10 NG”. When specified, it is composed of “OK” or “NG” indicating the result of whether or not the response WAIT time specification response message D2 has been received. The response result is printed out on a sheet such as a receipt by the printing unit 16 as shown in FIG. Alternatively, it is displayed on the display unit 12. Alternatively, the sound is output by the sound output unit 19. Note that the user can set in advance by which operation the response result is output by operating the input unit 11. When outputting the response result, as shown in the output example of FIG. 10, the version information of the application and network application used for communication with the information center server 2, the IP address, the subnet mask, and the gateway of the sales data processing device 1 Such information may be output together.

  When the response result is output, the process returns to step S201. On the other hand, when it is determined in step S202 that the end key has been pressed by the input unit 11 (step S202; YES), the port opening time confirmation process A ends.

  Returning to FIG. 4, when it is determined in step S4 that “2. Check port opening time (manual)” is not selected from the connection confirmation menu screen (step S4; NO), that is, “3. Check port opening time”. If “automatic” is selected, the port opening time confirmation processing B is executed (step S6).

  FIG. 11 is a flowchart showing the port opening time confirmation process B executed in the sales data processing apparatus 1. The port opening time confirmation process B is executed in cooperation with the CPU 10 and the processing program 141 stored in the storage unit 14.

  First, 0 is stored in the variable n, and a predetermined number of seconds (here, 10) is stored in the variable N (step S301).

  Next, the variable n is incremented by 1 (step S302), and it is determined whether n> N is satisfied (step S303). If it is determined that n> N is not satisfied (step S303; NO), a response WAIT time designation request message D1 (see FIG. 8) is created with n (seconds) as the response WAIT time (step S304).

  Next, the communication unit 15 transmits a response WAIT time designation request message D1 to the information center server 2 (step S305). Further, reception of a response WAIT time designation response message D2 (see FIG. 9) from the information center server 2 is waited until a predetermined time (n + α) elapses according to the response WAIT time n (step S306).

  When a predetermined time (n + α) has elapsed since the response WAIT time designation request message D1 has been transmitted, output data of a response result indicating whether or not the response WAIT time designation response message D2 has been received by the communication unit 15 is created and printed. The data is output by the unit 16 or the like (step S307).

  FIG. 12 shows an example of the output of the response result in step S307. FIG. 12 shows an output example when the response result is printed out on the receipt paper by the printing unit 16. As shown in FIG. 12, the response result output in step S307 specifies the response WAIT time (seconds) and the response WAIT time, such as “waiting time: 1 OK” or “waiting time: 10 NG”. In this case, it is composed of “OK” or “NG” indicating the result of whether or not the response WAIT time designation response message D2 has been received. The response result is printed out on a sheet such as a receipt by the printing unit 16 as shown in FIG. Alternatively, it is displayed on the display unit 12. Alternatively, the sound is output by the sound output unit 19. Note that the user can set in advance by which operation the response result is output by operating the input unit 11. When outputting the response result, as shown in the output example of FIG. 12, the version information of the application and network application used for communication with the information center server 2, the IP address, the subnet mask, and the gateway of the sales data processing device 1 Such information may be output together.

  When the response result is output, the process returns to step S302. On the other hand, if it is determined in step S303 that n> N (step S303; YES), the port opening time confirmation process B ends.

  For example, when the response result shown in FIG. 10 is output by the port opening time confirmation process A, or when the response result shown in FIG. 12 is output by the port opening time confirmation process B, the router R sends the information center server 2 It can be seen that the port for communication with is set to be closed in 4 seconds. For example, when it is assumed that communication between the sales data processing apparatus 1 and the information center server 2 takes about 10 seconds during actual operation, the information center server 2 is set during actual operation in the current setting of the router R. It can be seen that a communication error occurs without adapting to the response time from. Therefore, in such a case, the service person instructs the user to set the setting of the router R in advance to 10 seconds + α or more, and changes the setting of the router R in advance so that communication can be performed during actual operation. An error can be avoided.

Next, processing in the information center server 2 will be described.
FIG. 13 is a flowchart showing a telegram response process executed in the information center server 2. The electronic message response process includes a processing program 241 stored in the CPU 20 and the storage unit 24 when a response request message (confirmation packet or response WAIT time designation request message D1) is received from the sales data processing device 1 by the communication unit 25. It is executed by the cooperation.

  First, it is determined whether or not the received message is a response WAIT time designation request message D1 (see FIG. 8). If it is determined that the received message is a response WAIT time designation request message D1 (step T1; YES), a response is made. The system waits for the time designated by the WAIT time designation request message D1 (step T2). Next, a response WAIT time designation response message D2 (FIG. 9) is created (step T3), and the created response WAIT time designation response message D2 is transmitted by the communication unit 25 to the sales data processing apparatus 1 as the request source (step S3). T4). Then, the message response process ends.

  On the other hand, if it is determined that the received message is not a response WAIT time designation request message D1 but a confirmation packet (ICMP packet) by Ping (step T1; NO), a response (ICMP packet) is immediately created (step T5), the created confirmation packet is transmitted to the sales data processing device by the communication unit 25 (step T6). Then, the message response process ends.

  As described above, according to the network system 100, the CPU 10 of the sales data processing apparatus 1 specifies the response WAIT time for requesting the information center server 2 to transmit a response message after waiting for a predetermined response waiting time. A request message D1 is created and transmitted to the information center server 2 by the communication unit 15, and a response result indicating whether the response WAIT time designation response message D2 from the information center server 2 is received by the communication unit 15 within a predetermined time Is output by the printing unit 16 or the like.

  Accordingly, the service person or user confirms the response result, so that the communication environment to which the sales data processing apparatus 1 is connected can be applied to the response time from the information center server 2 assumed in actual operation. It is possible to confirm whether or not there is. If the communication environment is not applicable to the response time from the information center server 2 that is assumed during actual operation, it is necessary to take action such as changing the port opening time setting of the router R in advance. Communication errors during operation can be avoided.

  Further, according to the port opening time confirmation process A, the response waiting time of the information center server 2 can be designated in advance by the input unit 11, so that the response time assumed by the service person or the like during actual operation can be efficiently obtained. It is possible to specify and check the communication environment.

  Further, according to the port opening time confirmation processing B, the response waiting time of the information center server 2 is determined in advance, so that it is possible to easily check the communication environment without performing an operation for inputting a waiting time by a service person or the like. Can be performed.

  In addition, since the response result can be output from the printing unit 16, the display unit 12, or the voice output unit 19, the response result can be easily confirmed by the printed matter, the display on the display unit 12, or the voice.

In addition, the description content in the said embodiment is a suitable example of the network system 100 which concerns on this invention, and is not limited to this.
