Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing device such as a POS server.

[0002]

2. Description of the Related Art At present, a data processing device is used to efficiently perform various operations, and such a data processing device includes a POS server of a POS system. A POS server is a large number of connected POS
The sales data transmitted from the terminal is collected and accumulated, and the accumulated data is transmitted to the store processor in response to a request from the store processor.

The POS system as described above is, for example,
A plurality of POS servers are connected to one store processor via the data network, and a large number of POS terminals are connected to each of these POS servers via the data network. In a large store with a sales floor, a store processor is placed in the office, a POS server is placed in each of the backyards on multiple floors, and a POS terminal is placed in each of the many floors on each floor. .

In such a POS system, for example,
A PLU (Price) that stores product data such as product codes, product names, and selling prices that are individually set for many products.
Look Up) If a memory is provided on the POS server and data processing of product sales is executed at each sales floor,
The terminal reads the product data required for data processing from the PLU memory of the POS server.

Further, the POS terminal generates transaction data when it executes data processing for merchandise sales, transmits it through the data network, and the POS server receives the transaction data and stores it in the internal memory. . The store processor collects the transaction data accumulated by the POS server at a predetermined timing. Therefore, with this store processor, it is possible to comprehensively confirm the sales status of a plurality of sales floors.

With such a configuration, in a large store having a plurality of sales floors inside the building, the above-mentioned POS
Using the system, you can comprehensively plan sales strategies by comprehensively ascertaining the sales status of multiple sales floors. Moreover,
In such a POS system, since the POS terminal stores the product data used for the data processing of the product sale in the POS server, it is not necessary to store the product data individually in a large number of POS terminals. Therefore, the POS system as described above has a simplified overall structure, and the content of the product data can be easily changed.

[0007]

In the above-mentioned POS system, one POS terminal is used for many POS terminals.
A server is connected, which collects transaction data from all connected POS terminals and responds to inquiries from POS terminals.

However, since the exchange between the POS terminal and the POS server varies depending on the situation, it is difficult to determine the optimum number of POS terminals connected to the POS server. For this reason,
In a store that uses the POS system as described above,
When the number of POS terminals exceeding the capacity is connected to the S server, the operation delay of the POS terminals and the POS server hang-up may occur. Also, PO
If the number of POS terminals connected to the S server is limited more than necessary, the operating rate of the POS server with respect to the POS terminal may decrease, and the POS server may not be effectively utilized.

As described above, the POS server is excessively PO
When the S terminal is connected, problems such as operation delays may occur at the POS terminal, and it can be assumed that the POS server's capacity is insufficient, but it is difficult to confirm this. Implementation of appropriate measures such as reducing the number of vehicles tends to be delayed.

The above-mentioned problem does not occur not only in the POS server but also in various data processing devices that execute data processing by multitasking.

[0011]

A large number of data processing means for executing various data processings, an availability determination means for individually determining the availability of data processing of these data processing means, and this availability determination means are provided. A counter for counting the number of the data processing means judged to be executable, an operation rate calculating means for calculating the overall operation rate of a large number of the data processing means from the count value counted by the counter, and the operation rate calculation The operating rate display means for displaying the operating rate calculated by the means.

[0012]

The operating rate display means displays the operating rate of the data processing means, so that the operating rate of the data processing device can be easily confirmed in real time.

[0013]

An embodiment of the present invention will be described below with reference to the drawings. First, the POS server 1, which is the data processing device exemplified in this embodiment, is a part of the POS system 2. As illustrated in FIG. 1, the POS system 2 includes one store processor 3 installed in an office of a large store (not shown) and a plurality of POS servers 1 installed in a backyard or the like.

The LED array 22 and the like, which are connected in series, are connected via a system bus 23.

The POS server 1 has a PLU memory in which product data such as a product code, a product name and a selling unit price individually set for a product are stored in advance, and the CPU 7 described above.
A setting area for a plurality of tasks executed by the CPU, a counter area for counting the operating rate of the CPU 7 as a pause time for task execution, a data area in which a reference value composed of a maximum count value for one second is preset, It is provided in the RAM 9.

In the POS terminal 5 of the POS system 2, when the data registration means reads the product data from the PLU memory of the RAM 9 of the POS server 1 and executes the data processing of the product sales, the data is generated by the data processing of the product sales. The means generates transaction data, and the transaction data is transmitted to the POS server 1 by the DLC 6.

POS server 1 of this POS system 2
When the CPU 7 executes data processing such as data communication with the POS terminal 5, as will be described later as steps S3 and S4 in the flowchart of FIG. Each means is determined, and the counter counts the operating rate of the CPU 7, as will be described later as step S6. As will be described later in steps T1 and T2 in the flow chart of FIG. 5, this count value is read by the operating rate reading means at predetermined time intervals, and is counted by this counter as described later in step T3. The operating rate calculation means of the entire number of the data processing means calculates the operating rate from the count value, and the operating rate display for displaying the calculated operating rate as described later in steps T3 and T4. The means is adapted to display on the LED array 22 or the like.

More specifically, in the POS server 1, the count value of the operating rate accumulating means is read by the operating rate reading means every one second, and the read count value is read as described later as step T3. The operation calculation means divides the operation value by the reference value set in the RAM 9 to calculate the operation rate. In this POS server 1, the number of LEDs 21 corresponding to the calculated operating rate is turned on, so that the operating rate of the CPU 7 is displayed here as a percentage.

In this POS system 2, the POS terminal 5 installed in each of the plurality of sales floors selectively reads out the product data from the PLU memory of the RAM 9 of the POS server 1 and executes the data processing of the product sales. When the data processing of this product sale is executed, transaction data is generated and the POS server 1 is generated by the DLC 6.
It is designed to be sent to.

The POS server 1 has a plurality of connected Ps.
Since the above-mentioned data communication with the OS terminal 5 is executed,

When turned on, all the LEDs 21 of the LED array 22 are turned off (step S1), and initialization is performed to perform initial setting (step S2). The POS server 1 sequentially searches a large number of tasks (step S
3) It is determined whether or not an executable task is detected (step S4). If an executable task is detected, the data processing is executed and then the process returns to step S3 (step S5). If no executable task is detected, the count value in the counter area of the RAM 9 is set to "1". After adding "", the process returns to step S3 (step S6).

By doing so, the POS server 1 counts the time when the CPU 7 does not execute the task, so that the CPU that executes the multitask
When 7 is fully operating, the count value becomes "0", and when the CPU 7 that executes multitasking is completely idle, the count value becomes maximum and coincides with the reference value. This count value is read by the interrupt process every second and CP
The data processing of the POS server 1 for displaying the operation rate of U7 by the LED array 22 will be sequentially described below based on the flowchart of FIG.

First, the POS server 1 constantly monitors the elapse of one second (step T1). When this one second elapses, the count value is read from the counter area of the RAM 9 and copied to the work area of the RAM 9 ( Step T2).
By dividing the count value by the reference value set in the RAM 9, the idle operation rate is calculated as an operation rate of the CPU 7 in percentage (step T3). The number of LEDs 21 corresponding to the operating rate of this percentage is turned on (step T
4) After initializing the counter of the RAM 9, the interrupt processing is finished (step S5).

By doing so, the POS server 1 displays the operating rate of the CPU 7 in real time, so that the user can easily confirm the operating rate of the POS server 1. In this POS system 2, by checking the operating status of the POS server 1, the P

POS terminal 5 by connecting terminal 5
Can be prevented and the POS server 1 can be prevented from hanging up, and the POS server 1 can be prevented from having a low operating rate due to the small number of POS terminals 5 connected to the POS server 1.

Even if a problem such as an operation delay occurs in the POS terminal 5 in this POS system 2, P
By confirming the operating status of the OS server 1 with the LED array 22, it is possible to easily determine whether or not the cause is the insufficient capacity of the POS server 1, and it is appropriate to add or upgrade the POS server 1. It is possible to quickly take various measures.

In the POS server 1 of this embodiment,
Although it has been illustrated that the operating rate of the CPU 7 which is the data processing means is displayed by the number of lit LEDs 21 of the LED array 22, the present invention is not limited to the above embodiment, and such operating rate is a dedicated meter. It is also possible to display the position of the pointer of (3) or a graph image of the CRT display 10 (both not shown).
