DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the POS terminal system of the present invention will be described in detail with reference to the drawings.
[0011]
FIG. 1 is a block diagram showing a POS terminal system according to an embodiment of the present invention. The POS terminal system stores two POS terminals 1a and 1b connected to the Ethernet work 3 and data required for necessary management processing by each of these POS terminals 1a and 1b, and is connected only to the Ethernet work 3 respectively. 2 disk devices 2a and 2b. That is, in this POS terminal system, the two POS terminals 1a and 1b and the two disk devices 2a and 2b are connected only to the Ethernet 3 respectively.
[0012]
Here, the POS terminals 1a and 1b perform a proxy process for reading / writing data to / from a disk device 2a or 2b corresponding to the one corresponding to the POS terminal 1a or 2b according to a preset proxy process identifier. The control units 4a and 4b for canceling the execution of the proxy process according to a preset proxy process canceling identifier and the execution of the proxy process by the control units 4a and 4b when pressed, Substitution processing keys 5a and 5b for inputting operation instructions for reading and writing data via Ethernet 3 with respect to another in 2a and 2b, and substitution processing by control units 4a and 4b when pressed. As the cancellation of execution, data is read / written via the Ethernet work 3 for each disk device 2a, 2b corresponding to itself. Alternate process release key 6a for operation instruction input to, and 6b are provided, respectively.
[0013]
In these control units 4a and 4b, the proxy process identifier and the proxy process release identifier are flags such as 0, 1, 3,... Set based on specific control codes corresponding to the input instruction information, respectively. ing. For this reason, the proxy processing keys 5a and 5b and the proxy processing cancel keys 6a and 6b provided in the keyboards of the POS terminals 1a and 1b are, as input instruction information for the control units 4a and 4b, flags of proxy processing identifiers, respectively. It is possible to set a flag for the proxy processing release identifier.
[0014]
Therefore, in this POS terminal system, if the proxy processing keys 5a and 5b in the POS terminals 1a and 1b are pressed to indicate the proxy processing, the control units 4a and 4b use the Ethernet 3 to perform the proxy processing in the disk devices 2a and 2b. The management processing operation by the proxy processing is performed by reading / writing data in the disk device 2b different from the one corresponding to itself (the disk device 2b when the proxy processing key 5a is pressed, and the disk device 2a when the proxy processing key 5b is pressed). Do.
[0015]
Also, if the proxy processing cancellation keys 6a and 6b are pressed to indicate the normal state in which the proxy processing is canceled, the control units 4a and 4b correspond to the disk devices 2a and 2b themselves via the Ethernet work 3 ( When the proxy process cancel key 6a is pressed, the disk device 2a is read and when the proxy process cancel key 6b is pressed, the disk device 2b) is read / written to perform normal management processing.
[0016]
FIG. 2 is a functional block diagram shown for explaining an access operation related to the proxy processing function of the POS terminal system.
[0017]
Here, when the POS terminal 1a is out of order and the POS terminal 1a cannot perform the normal management processing operation or the management processing operation by the proxy processing, the proxy processing key 5b in the POS terminal 1b is pressed. When a control code is input and execution of proxy processing by the control unit 4b is instructed, the control unit 4b executes proxy processing by setting a unique flag according to the control code for accessing the disk device 2a. It shows that the operation MX of the management process by the substitution process is performed by reading / writing data of the disk device 2a via the Ethernet 3.
[0018]
Further, when the proxy process cancel key 6b in the POS terminal 1b is pressed to input a control code and the control unit 4b instructs to cancel the proxy process, the control unit 4b uses the control code for accessing the disk device 2b. When a corresponding unique flag is set, the normal state is entered, and the data M of the disk device 2b is read and written via the Ethernet 3 and the normal management processing operation MN is performed.
[0019]
In the POS terminal system having such a proxy processing function, the data of the disk device 2a, which has been conventionally discarded due to a failure of a specific POS terminal 1a, is read and written from another POS terminal 1b to perform proxy processing. Even if an abnormality occurs in 1a, management processing can be executed without any problem on the entire system, and only the failure of the POS terminal 1a requires repair / recovery.
[0020]
In the POS terminal system of one embodiment described above, two POS terminals 1a and 1b and two disk devices 2a and 2b corresponding to these POS terminals 1a and 1b are connected to the Ethernet work 3. As described above, the number of POS terminals and disk devices may be three or more.
[0021]
【The invention's effect】
As described above, according to the POS terminal system of the present invention, data of the disk device corresponding to the failed POS terminal, which has been conventionally discarded due to the failure of a specific POS terminal, is read / written from another POS terminal. Therefore, even if a specific POS terminal malfunctions, management processing can be executed without any problem for the entire system, and only the faulty POS terminal requires repair and restoration. Repair and restoration of the faulty POS terminal Later, the management process can be executed as usual without restoring the data of the disk device corresponding to the POS terminal.
