Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing system in which a plurality of data processing devices are connected via a line.

[0002]

2. Description of the Related Art In recent years, in a large store or the like, a data processing device installed in each sales floor, for example, a slave side ECR
Adopted a data processing system in which (electronic cash register) is connected inline to a predetermined data processing device, for example, ECR on the master side, and sales data transmitted from each slave side is collected on the master side. Has been done. In some of such data processing systems, the master side has a schedule function of collecting data of each slave side when a predetermined time is reached. That is, for example, if the command file number “1” is set to collect the adjustment data and inspection data of all slaves from the inline to the master side at the execution time “15:00”, the set time is reached. The collection is performed.

[0003]

However, in the data transfer system having the schedule function as described above, the collection processing is surely performed at the set predetermined time even when the master ECR is in the registration mode. Since registration is prohibited during this period, there is a problem that the waiting time for customers is further increased when a large number of customers are waiting for registration. Further, if the customer registration is prioritized, the collection process will not be executed at the set predetermined time. An object of the present invention is to notify that the collection processing will be performed when the current time reaches a predetermined time, and to execute the collection processing in its own data processing device when the notification is performed, or This is to instruct whether the data processing device should execute the collection process so that the collection process can be appropriately executed by the schedule function according to the waiting state of the customer.

[0004]

The means of the present invention are as follows. A data processing system in which a plurality of data processing devices are connected via a line, and for a predetermined data processing device among the plurality of data processing devices, the data of each data processing device is transferred via the line. A collecting function for collecting is assigned, and it is set that this collecting function is automatically executed at a predetermined time. The predetermined data processing device includes the following means. The current time storage means stores the current time.
The predetermined time storage means stores the predetermined time at which the collection function is automatically executed. The determining means determines whether or not the current time has reached the predetermined time. When it is determined by the notifying unit and the determining unit that the current time has reached the predetermined time, a notification that prompts execution of the process of the collecting function is performed. The selection instructing means, when notified by the informing means, arbitrarily selects whether to execute the processing of the collection function by itself or in another data processing device. To do. The collection processing execution means executes the processing of the collection function when the selection instructing means gives a selection instruction to execute itself.
Any one of the other data processing devices connected through the line when the selection instructing device selects and instructs the execution means to execute in any of the other data processing devices.
Specify one data processor. The execution instructing unit instructs the data processing device designated by the designating unit to execute the process by the collecting function.

Therefore, the key input signal output from the input unit 11 corresponding to the operation key or the mode designation signal output according to the switching position of the mode changeover switch MS and the master / slave changeover switch M / S is a CPU (central processing unit). It is input to the processing circuit) 12.

The CPU 12 controls various operations according to a microprogram stored in advance,
For example, input processing, registration processing, data transmission processing, data collection processing, etc. are executed. Then, the CPU 12
In addition to A, B, C, D, E, and registers used for arithmetic operations and the like, the arithmetic unit and the control unit are provided. Then, the CPU 12 is a RAM (random access memory) 1
Data is exchanged with the data storage unit 3 to accumulate various data in the RAM 13, and the opening operation of the drawer 14 is controlled.
The display unit (fluorescent display tube, etc.) 15 digitally displays sales data and the like, and the printing unit (thermal printer, etc.) 16 is driven to print the sales data on receipt paper and journal paper. Read the time.

The RAM 13 is for controlling data reading and writing operations under the control of the CPU 12, and is a PLU.
In addition to another total memory M1, transaction total memory M2, and other total memory M3, preset schedule content storage unit M4, schedule time storage unit M5, and machine number of another ECR to which the schedule content is to be transferred are stored. A machine number storage unit M6 is provided. The schedule content storage unit M4 and the schedule time storage unit M5
It is possible to store a plurality of schedule contents and time.

FIG. 1B shows the structure of the slave side ECR3 .... Incidentally, the slave side ECR3 of this embodiment
.. is configured to be capable of functioning as a master, and therefore has substantially the same configuration as that of the master side ECR1. The slave side ECR 3 is not provided with a clock circuit section, and the RAM 13 is not provided with a schedule content storage section and a schedule time storage section.

Operation of Embodiment FIG. 3 shows the ECR1 on the master side at regular time intervals, specifically 1
It is a flow chart which is started by interruption every second. First, when entering this flow, the schedule times corresponding to a plurality of preset schedule contents are sequentially read from the RAM 13, loaded into the B register in the CPU 12, and compared with the current time read from the clock circuit section 11 into the A register. , The match is detected (step S1). Here, if it does not match any of the schedule times, this interrupt processing ends, but if it is detected that any of the schedule times matches, the process proceeds to step S2, and the schedule time of the match detected The corresponding schedule contents are read from the RAM 13 and CP
It is set in the D register of U12. Then, it is checked whether or not it is currently registered (step S3), and if it is not registered, the schedule disclosure display lamp LP for clearly indicating the start of the schedule is turned on (step S4). This allows the cashier to confirm that the scheduled time has come, but when there are many customers and registration is busy, the BUSY key KC is operated. in this case,
By operating the BUSY key, BUS will be stored in the C register of CPU2.
Since the Y input code is set, whether or not the BUSY key is operated is checked according to the contents of the C register in the next step S5, but if it is not operated, a fixed time (for example, 10 seconds) has elapsed since the scheduled time. Is checked (step S6). If the predetermined time has not elapsed, the process returns to step S4. If the BUSY key is not operated even after a lapse of a certain time after the scheduled time, the schedule start display lamp LP is turned off (step S7) and then the schedule content called to the D register, for example, all A process of collecting settlement data or inspection data on the slave side is executed (step S8). When the execution of the schedule contents is completed, finally, an initialization process (step S9) for clearing A, B, C, D, E and the register is performed.

On the other hand, even if the scheduled time comes, it is detected in step S3 that registration is in progress, or that the BUSY key has been operated within a certain time after the scheduled time comes in step S5. In this case, the process proceeds to (step S10), the contents are read from the transfer machine number storage unit M6 of the RAM 13, the slave side ECR3 corresponding to the machine number is selectively designated, and the schedule in the D register is designated to the ECR. Transfer the contents. Here, the transfer machine number is predetermined, and one of the plurality of slave side ECR3 ... Is designated. Then, when such schedule contents are transferred, A, B, and
The contents of the C and E registers are respectively cleared (step S
11). Therefore, in this case, the master side does not execute the schedule content, the slave side ECR is designated, the schedule content is transmitted, and the schedule right is transferred to the ECR.

FIG. 4 is a flowchart of the slave side ECR 3 executed by an interrupt when the schedule contents are transmitted from other ECRs (including the slave side ECR). First, when entering this flow, it is checked whether or not registration is currently being performed (step S21). here,
If registration is not in progress, it is checked whether the BUSY key has been operated within a fixed time after turning on the schedule start display lamp LP (steps S22, S23, S24).
As a result, if the BUSY key is not operated within the fixed time, the schedule start display lamp LP is turned off (step S25). Then, the schedule contents are executed based on the contents of the A register in which the transferred schedule contents are stored (step S26), and thereafter, the schedule contents, the machine number of this slave ECR and the execution completion code of the schedule. To the master side (step S27). And A, B, C
The contents of each register are cleared (step S2)
8).

On the other hand, even if the schedule contents are transmitted from another ECR, if the contents are currently registered or the BUSY key is operated within a fixed time, step S21,
This is detected in S23 and the process proceeds to step S29,
Contents of A register (schedule contents transferred)
Is transferred to another ECR designated by the content of the B register (schedule content transfer machine number read from the RAM 13). Then, in step S28, A, B, C
The contents of the registers are cleared respectively. Therefore, in this case, even if the schedule execution right is transferred from the master side ECR1, the schedule contents are not executed in the ECR concerned, and another ECR is designated to transfer the schedule contents to another ECR to execute the schedule execution. The right is further transferred to the next slave side ECR3. In this way, the slave side ECR3 ... Is sequentially specified to check whether it is being registered or has a BUSY input. As a result, the schedule contents are executed in the ECR only when there is no BUSY input even during registration. , All slave ECRs
3 ... is being registered or has a BUSY input, the master side ECR is the last specified slave side ECR3.
The schedule content is transferred by designating 1 to restore the schedule content.

FIG. 5 shows that in the ECR 1 on the master side, when the schedule contents are transferred from the slave side and returned, or the schedule contents, machine number, and execution end code are transmitted from the slave side as the schedule is executed on the slave side. It is a flowchart in which execution is started by interruption when each is transferred. First, when this flow is entered, it is checked whether or not the schedule execution right is being transferred according to whether or not there is data in the D register. (Step S31). Now, if the contents of the schedule have already been executed on the master side, the contents of the D register have been cleared, so an error will occur, but if the schedule execution right is being transferred, is there an execution end code in the transmission data? In other words, it is checked whether the slave ECR 3 has executed the schedule contents (step S32). Now, assuming that the slave side has executed the schedule contents, the process proceeds to step S33, and the schedule contents and the machine number are printed and displayed respectively. This makes it possible to confirm in which ECR the schedule content was executed. Then, if it is determined in step S32 that there is no execution end code, the process proceeds to step S34 to check whether registration is in progress, and if registration is in progress, a registration process (step S3
5) is executed to check whether registration is completed (step S3).
6) If the registration is not completed, the process returns to step S35 and waits until the registration is completed. Then, if the registration is not in progress or the registration is completed, the process proceeds to step S37 and D
The schedule contents are executed based on the contents of the register. Then, the contents (scheduled contents) of the D register are cleared (step S38). Therefore, if the schedule contents are not executed in all the ECRs on the slave side and the schedule contents are returned to the original master side, the schedule contents will be executed after the registration ends if the registration is in progress, In this case, the schedule execution right is not transferred to the slave side.

As described above, basically, the master side executes the schedule contents in this embodiment, but when the schedule contents cannot be executed, the schedule execution right is transferred to the slave side. Here, in a specific case where the transferred slave-side ECR cannot execute it, the schedule execution right is transferred from this slave-side ECR to another slave-side ECR. In this way, the schedule execution right is sequentially transferred to the slave side ECR, and when the slave side ECR in the executable state is searched, the schedule is executed by the ECR. Therefore, the schedule content can be executed without causing the customer to wait, and at the set time, it will be executed at that time as much as possible.

In the above embodiment, when the schedule contents are transferred to all the slave ECRs and then returned to the original master ECR, the schedule contents are not transferred to the slaves. I did
The schedule content may be cyclically transferred until the schedule is executed. Alternatively, the master side may sequentially specify the slave side to inquire whether or not the schedule can be executed.

Further, the time when the schedule is executed may be stored in correspondence with the scheduled time.

Further, when the schedule content is executed on the slave side, the schedule content (collected data etc.) may not be printed on the slave side, but may be transmitted to the master side and printed on the master side.

Further, although the schedule contents are automatically executed at the set time in the above-mentioned embodiment, execution of the schedule contents may be instructed by key input on the master side.

[0020]

According to the present invention, when the current time reaches a predetermined time, it is notified that the collection processing is to be performed, and when this notification is performed, it is executed by its own data processing device, or Since it is possible to instruct whether to execute it on another data processing device, if the registration process etc. ends immediately when the registration process etc. is being executed in its own data processing device, collect it in its own data processing device. Appropriate execution of the collection process depending on the waiting state of the customer etc. by executing the process immediately, and if the registration process etc. does not end immediately, make the other data processing device execute the collection process. You can do it.
