Abstract

PURPOSE:To reduce influence due to the fault of a sales data storing place and a data transmitting equipment by providing the switching means of the sales data storing place. CONSTITUTION:Plural POS registers 1 providing a sales processing part 11, a sales data storing place switching part 12 and a data file 13, plural terminal controllers 2 providing the data file 21 and a central processing unit 3 providing the data file 31 are connected so as to constitute a system. The sales data storing place switching part 12 transfers sales data to the data file 31 of the central processing unit 3. When the transfer is impossible, it transfers sales data to the data file 21 of the controller 2. When the transfer is also impossible, it stores sales data in the data file 13 inside the self POS register 1. Thus, an input processing from the POS register 1 is prevented from immediately becoming impossible even if the fault occurs in a data storage destination.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sales data collecting system, and in particular, a PO comprising a POS register, a terminal controller and a central processing unit connected by a bus system.
The present invention relates to a sales data collection method of the S system.

[0002]

2. Description of the Related Art Conventionally, this type of sales data collection method has been
Sales data are stored in a data file in the POS register, some are stored in a data file in the terminal controller, and finally transferred to the central processing unit for storage. It is fixed.

[0003]

In the above-mentioned conventional sales data collection method, since the storage location of the sales data at the time of sales is fixed, the failure of the sales data storage device or the data transmission equipment to the storage destination. In case of failure, POS
It may not be possible to input data to the register.
There is a drawback that the S system is stopped.

[0004]

The sales data collecting method of the present invention is a sales data collecting method for a POS system comprising a POS register, a terminal controller and a central processing unit connected by a bus system.
If the sales data in the OS register can be stored in the central processing unit from the POS register, it is transferred to the data file of the central processing unit, and if this transfer is not possible, it is transferred to the data file of the terminal controller. It is configured by having a switching means of the sales data storage location stored in the internal data file.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.
The embodiment shown in FIG. 1 has a plurality of P's each having a sales processing unit 11, a sales data storage location switching unit 12, and a data file 13.
An OS register, a plurality of terminal controllers having a data file 21, and a central processing unit 3 having a data file 31 are connected by a bus 4. In FIG. 1, there are only one POS register and one terminal controller. Only the POS register 1 and the terminal controller 2 are shown.

FIG. 2 is a sales data storage location switching unit 1 of FIG.
With reference to FIG. 2, the process of storing the sales data processed by the sales processing unit 11 by the sales data storage location switching unit 12 will be described below with reference to FIG. When the sales data is input to the sales data storage location switching unit 12 (step 101), the state of the storage destination is checked, and if the transfer to the first priority central processing unit 3 is possible, the central processing unit 3 is executed. Is transferred to the data file 31 (steps 102 and 103). As a result, it is checked whether the data is transferred without any abnormality (step 104). If the data is transferred correctly, the process returns to step 101 to continue inputting the next sales data. If it is not transferred correctly, the transfer destination is switched to the terminal controller 2 (step 105). Then, the data is transferred to the data file 21 of the terminal controller (step 106). As a result, it is checked whether or not the data is correctly transferred without any abnormality (step 107). If the data is transferred correctly, the process returns to step 101. Store (step 10)
8, 109). In this case as well, it is checked whether the data has been stored correctly (step 110).
The process returns to step 1, but if it is not stored correctly, an error is displayed (step 111) and the process ends. Note that step 102
When the transfer to the central processing unit 3 having the first priority is impossible due to a failure or the like, the transfer to the terminal controller 2 having the second priority is selected, and the process immediately proceeds to step 106. Further, if the transfer to the second-priority terminal controller 2 is in a transfer-disabled state for any reason in step 102, the process immediately proceeds to step 109.

[0008]

As described above, according to the present invention, when the storage location of the sales data cannot be stored in the data file of the central processing unit, it is stored in the data file of the terminal controller and when it cannot be stored in the data file of the terminal controller. Has a switching means for storing in the data file of its own POS register, so that even if a failure occurs in the data storage destination, it is possible to prevent the input processing from the POS register from being immediately disabled. is there.
