Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data collection control method for a plurality of electronic cash registers, and in particular, for example, a data collection control method for a plurality of electronic cash registers, each including a storage means for storing a plurality of types of registration data by type. The present invention relates to a data collection control system for a plurality of ECRs (hereinafter referred to as ECR) that collects and controls registered data to one collective control device via a data bus.

In general, ECRs are in practical use that allow easy registration operations and quick registration processing.

In such an ECR, for example, when data such as the price of a single item or department information of a single item is registered by manual key operation, it can be used to create daily (or weekly) reports later for use as management materials.
Registration data is cumulatively stored in memory (or magnetically recorded on magnetic tape).

In order to create a daily report based on the data registered in this way, conventionally, after closing, staff would collect and store the registered data of each ECR in a storage device, collect magnetic tapes, and centrally store the collected data. This is done by performing arithmetic processing using an arithmetic processing device (for example, a general-purpose computer).

Furthermore, a data bus is used to connect the plurality of ECRs and the central processing unit online, and the registered data of each ECR is transmitted and collected in time order.

However, while the former method, in which staff members collect the registered data of each ECR after the store has closed, has the advantage of being able to collect data at a low cost, it can only be collected after the store has closed, making it difficult to know the ever-changing data. The disadvantages include the inability to perform data collection and the complexity of processing after data collection.

The latter method of collecting data online using a general-purpose computer has the advantage of being able to collect data quickly, but is extremely expensive.

Therefore, a control system that is a relatively inexpensive device and that can quickly collect data is desired.

Additionally, if multiple ECRs are placed in different sections (or floors) of a sales floor, it is necessary to collect registration data for each sales floor, so it is not possible to specify the desired ECR and collect registration data. desirable.

Furthermore, the collected registered data can be used not only for creating daily reports, but also as materials for creating weekly and monthly reports, so it can be stored for a certain period of time (for example, one week in the case of a weekly report) and It is desirable to be able to create materials with simple operations.

Therefore, the main object of the present invention is to be able to quickly, inexpensively, and efficiently collect registration data of a plurality of ECRs, and to selectively collect data by specifying a desired ECR among the plurality of ECRs. Multiple ECHs that can be collected
The purpose of this invention is to provide a data collection control method.

Another object of the present invention is to provide a data collection control system for a plurality of ECRs, which allows easy creation of materials for different periods, such as daily reports, weekly reports, and monthly reports.

To summarize this invention, each of the plurality of ECRs is provided with a memory for storing registration data, and the collective control device that collects and controls the registration data of the plurality of ECRs collects and controls the registration data of the plurality of ECHs by type ( or each type of ECR), a second storage means that cumulatively stores the registration data stored in the first storage means for a certain period of time, and Provide a means to specify any table in the house.

Then, the registered data of any specified machine is stored in the first storage means or the second storage means, and a daily report is created by printing and recording based on the data stored in the first storage means. Data stored in the second storage means is printed and recorded to create materials for a certain period of time (for example, weekly reports, monthly reports), and each ECH's registered data is stored in the second storage means. This is a control method that clears the memory.

FIG. 1 is a block diagram showing an outline of the present invention.

In the figure, one collective control device (condelivery data: C
DT) 10 and the plurality of ECRs 30 are each connected via a data bus.

Each of these multiple ECRs has a machine number (hereinafter referred to as machine number) that is unique to each machine (for example, a 3-digit number). Enter the device number (ECR) of each ECH up to the number corresponding to the number of devices (for example, 16 for 16 devices).
The explanation will be given assuming that ECRI1 to ECRI6) are determined and the machine number is also determined.

The consolidator (CDT) 10 transmits data to each ECR 30 as will be described in detail later, and controls the collection of registered data from a plurality of ECRs 30.

FIG. 2 shows the consolidator 10 which is a feature of the present invention.
An example of the operation panel is shown below.

In the figure, the operation panel of the consolidator 10 includes a keyboard 20 including numeric keys 21, function keys 22 and 23, and a mode selection switch 24, and a printer that prints out data to create tables such as daily reports based on registered data. 25, a numeric display 26 for displaying a machine number or device number, and a function display 2γ are provided.

Specifically, the function key 22 is the numeric key 21
a code key 22a for specifying that the numerical value entered by operating is a department code; a start key 22b for issuing a start command; a data code key 22C for specifying the type of data to be collected; A zam key 22d that instructs the zam memory (to be described later) to be stored, a device key 22e that specifies that the numeric value input using the numeric key 21 is a device number, a clear key 22f, and a numeric value input using the numeric key or a machine number. and a key 22g for specifying that.

Further, the function key 23 includes a skip command key 23a for issuing a skip command by manual operation, and a skip command key 23a for issuing a skip command by manual operation.
Use the Z key 23b and the numeric keys 21 to input numerical values or enter each EC.
and a date setting key 23C for specifying that the date setting information is to be preset to R.

The mode selection switch 24 is for selecting a desired mode from among a plurality of modes by switching a key switch, for example, and includes a preset mode P for setting the date and department code in each ECR, an inspection mode X, and a payment mode. Mode Z and off mode OFF are selected as appropriate.

In addition, in this embodiment, when collecting the registration data by type of each ECR in the read memory (first memory) shown in the third section described later, the inspection mode is selected and the registration data is collected and stored in the read memory. If the registered data is to be stored cumulatively in the thumb memory (second memory) shown in FIG. 3, this is done by selecting the payment mode.

The function display 2γ includes, for example, a lamp 27a that indicates an operational error, a lamp 27b that indicates that data is being transmitted, a lamp 27c that indicates that an error has occurred during data transmission, and a memory display. It includes a lamp 27d that indicates overflow and a lamp 27e that indicates that printing paper is out.

FIG. 3 is an illustrative diagram showing an example of how the keyboard is operated in each mode. In particular, FIG. 3a shows an example of how to operate the preset mode, and FIG. FIG. 3C shows an example of the operation when performing the dump mode in the payment mode, and FIG. 3D shows an example of the operation when changing the secret number.

In Figure 3a, multiple ECR30 units are installed on the CDT10 side.
When setting the date by setting and inputting information to be preset (for example, date), operate the numeric keys 21 to enter the device number (or ECR) to be preset.
After manually inputting the CR-specific machine number), press the device key 22e, then operate the numeric keys 21 to input the year, month, and day to be set, and press the date key to indicate that the number you just entered is the date. Press 23e.

In addition, when setting the date to a certain arbitrary plurality of ECHs, input the device number for each ECH.

When setting the date on all ECHs, the user directly operates the numerical keys to input the date and then presses the date key 23e without inputting the device number or pressing the device key 22e.

In addition to date setting data, for example, if a department code is to be set, the code key 22a may be pressed instead of the key 23e.

In FIG. 3b, if data is to be collected by type of registered data of each ECR into the read memory (first storage means) described later, after selecting the mode selection switch 24 to inspection mode X, operate the numeric key 21. EC for which data should be collected
Enter the R's device number (or machine number), press the device key 22e, and operate the numerical keys 21 to enter a code (report code; for example, sales numbers by department) that specifies the type of data to be collected. Enter the total amount, the number of transactions for each transaction type such as cash sales and credit sales, and the total amount, etc., press the data key 22c, and then press the X/Z key 23b.
By pressing , the dump mode is performed in the inspection mode.

In FIG. 3C, if you want to collect data by type of registered data for each ECH into a read memory (described later) and cumulatively collect data into a thumb memory (second storage means), which will be described later, select the mode selection switch 24 to select the settlement mode. After selecting Z, operate the numeric key 21 to select the ECR for which data should be collected.
input the device number, press the device key 22e, operate the numeric keys to input the report code, and press the thumb key 22d to instruct storage in the thumb memory.

When data is collected in the thumb memory, the registered data in the ECR memory is cleared, so in order to allow operation only by a specific person, a secret number known only to those who can operate the payment mode is set and stored.

Therefore, when a secret number is input by operating the numerical keys 21, the manually entered secret number is compared and verified with a preset secret number.

If both secret numbers match, then press the X/Z key 23
By pressing b, the dump mode is executed in the settlement mode and at the same time, the memory of the designated ECH is cleared.

In Fig. 3d, when updating the secret number, operate the numeric keys 21 to input the secret number to be updated, press the key (#) 22g, and then operate the numeric keys 21 to update the old secret number. Enter the secret number and press the X/Z key 23b.

If the old secret number is a preset secret number, the old secret number is cleared and the new secret number is updated and stored.

As described above, operations are performed for each mode, and data transmission processing as explained in FIGS. 5 and 6 below is performed based on the selected mode.

The read memory 12a and the thumb memory 12b are configured, for example, to commonly store the same type of data of a plurality of ECRs according to the type of data registered in the ECR, or to store the same type of data in each ECF according to the type of data. is configured to store data for each time.

To explain the specific functions of each flag, Fe
The p flag is a flag that is set in response to no output from the clock generator 32 included in the ECR 30 in order to remember that the power to the ECH for data transmission has been cut off.

The Fap flag is set in response to the output of the coincidence circuit 16 (that is, when an interrupt permission signal is given from the ECR), and stores the possibility of data transmission with the core ECR.

The Fs flag is a flag that is set when a certain ECR skips to the next ECR due to data transmission being disabled due to power cut, etc. during data transmission time-sequentially with each ECR, and is a flag to remember that a skip operation has occurred. It is.

The Fd flag is set for each ECH by selecting inspection mode X or payment mode Z with the mode selection switch 24.
This flag is set when a mode for collecting registered data (hereinafter referred to as dump mode) is selected, and is in a reset state in preset modes other than dump mode.

The Fw flag is a flag that is set when it is necessary to wait for a certain period of time.

Each of the plurality of ECRs 30 includes an arithmetic control section 31, a clock generator 32, and a reception buffer register 33R that temporarily stores data transmitted from the CDT 10.
A transmission buffer register 33T that temporarily stores data to be transmitted to the CDTIO, and a memory (registered data storage means) 34 that stores registered data registered in the ECH by data type by operating a keyboard (not shown). ,CDT
When transmitting data from 10, the FI flag is set in response to a signal (inquire signal; INQ) indicating that there is data transmission.

The memory 34 included in each ECR 30 stores, for example, the number of sales items and total sales amount for each department code, the number of transactions and settlement amount for each transaction type such as cash sales, credit sales, and card sales, and the person in charge (operator). ) Store registered data by data type, such as the number of different transactions, total amount, etc.

FIG. 5 is an illustrative diagram for explaining the operation when transmitting data according to the present invention.

Next, referring to Figures 2 to 5, consolidator 1
The operation when controlling data transmission from ECR 0 to a certain ECR will be explained.

For example, the preset data (for example, date setting data and date code) input by operating as shown in FIG.

Then, the arithmetic control section 11 continues to store the date setting data in the buffer register BP, and also sends the write clock to the clock switching circuit 15 to the transmitting buffer register 14T.
to write and store the date setting data.

At this time, if the ECR with the specified device number is not in the registration operation, an appointment (A
Since the PP) signal is applied via the transmission buffer register 33T, the coincidence circuit 16 detects the APP signal and sets the Fap flag.

In response, the arithmetic control unit 11 provides the Fi flag with an inquire (INQ) signal indicating that data will be transmitted, thereby setting the Pi flag.

At this time, the clock switching circuit 15T applies a clock synchronized with the ECR provided from the clock generator 32 of the ECR 30 to the transmission buffer register 14T as a read timing signal, and reads the date setting data stored in the buffer register 14T. Date setting data is transmitted to the ECR 30 for reading.

At the same time, the reception buffer register 33R reads and stores date setting data in synchronization with the clock of the clock generator 32.

Then, the ECH arithmetic control unit 31 transmits data indicating that the preset data has been loaded and provides it to the data capture determination circuit 18, so that the data capture determination circuit 18 indicates that the data has been captured. Derive the output and set the Fr flag.

The arithmetic control unit 31 determines whether the transmitted preset data is normal or not (for example, it is abnormal if the date setting data is September 31st, or abnormal if there is a transmission error).

If the transmitted preset data is normal, the transmitted preset data is stored as an answer backup data in the transmission buffer register 33T and transmitted to the CDT 10.

At this time, the clock switching circuit 15R is connected to the clock generator 3.
The answer back data is read into the reception buffer register 14R in synchronization with the clock given from 2 and stored.

Also, when answer back data is given, the pan flag is set to remember that some data has been returned.

When the data is transmitted normally, the preset data is transmitted to each of the other ECRs in the same way.

In this way, the preset data is transmitted to the ECR 30 and the settings are registered.

On the other hand, if the preset data is abnormal, the calculation control unit 3
1 indicates that an abnormality is detected.The rFJ signal is given to the transmission buffer resistor 33T as an answer backup data to be stored therein, and is also transmitted to the CDT 10.

Accordingly, the receiving buffer register 14R is all rFJ.
The signal is stored, and the Fan flag is set.Furthermore, the miss data determination circuit 17 determines that the data is a miss based on the presence of the rFJ signal, and sets the Fm flag.

Based on this Fm flag being set, the arithmetic control unit 11 blanks the data storage area of the transmission buffer resistor 14T and enters a clear code into the function code storage area, and then receives the APP signal from the ECR 30 to flag the Fi flag. At the same time as setting the buffer resistor 14 again.
The data stored in T is transmitted to the ECR 30.

This transmitted data is transferred to the reception buffer register 33H.
When stored, the arithmetic control unit 31 clears the transmission buffer register 33T to all zeros, and supplies the all zeros to the reception buffer register 14R of the CDT 10 for storage.

Then, the date setting data is transmitted to the ECR 30 again in the same manner as described above.

At this time, if the abnormality is due to a transmission error at first, repeating this several times will successfully set and register the preset data in the ECR 30.

In addition, if you enter settings while operating the keyboard 20,
No matter how many times the preset data is transmitted, it will be determined that the data is a mistake, so if the data is not normal even after transmitting the data a predetermined number of times (for example, three times), the lamp 27a will be lit to indicate an error.

Next, a specified number of ECRs out of multiple ECRs
Or, explain specific operations when transmitting data to all units or when an abnormality occurs (for example, power cutoff or data transmission error).

FIG. 6 is a flowchart for explaining the specific operation of the present invention.

FIG. 7 shows an example of a time chart for explaining the specific operation of the present invention. In particular, for example, when transmitting a preset data to all (16) ECRs, and when collecting data in the settlement mode (dump mode) is a time chart.

Next, the operation of this embodiment will be explained along flowcharts with reference to FIGS. 2 to 7.

First, let's explain the case where preset data (for example, date setting data) is set in all ECRs.

When setting the date setting data, the date data to be set is entered manually as in the operation shown in FIG. 3a described above.

Then, in step 0 (abbreviated as Sp in the diagram), it is determined whether or not the device number of the ECR to which data is to be transmitted is specified. Proceed to step 1, and if specified, proceed to step 2.

In this explanation, we will move on to step 1, assuming that data will be transmitted to all ECRs.

In step 1, after setting the device number to "1" (i.e. ECRI), step 2 determines whether a machine number indicating that the machine is stopped is stored (
In other words, whether the flip-flop corresponding to device number "1" indicating that the ECR is stopped is installed or not)
Determine.

At this time, unless the stopped machine number is registered in advance in the initial state, it will not be known even if a subsequent cause of the stop occurs, so it is determined that the machine number is not registered and the process proceeds to step 3.

In step 3, the calculation control unit 11 issues the device number "
1" is displayed on the numerical display 26.

In step 4, the Fap flag is reset and the error counter ECT is set to a value of three.

In step 5, the date setting data to be reset is transferred to the transmission buffer register 14T and the process is terminated.

Then, in the next step 6, it is determined whether or not the Fap flag is set. If it is normal at this time, an interrupt permission signal is continuously given from the ECR of device number "1", so the above-mentioned It is set immediately after being reset in step 4.

Therefore, it is determined that the Fap flag is set and the process proceeds to step γ.

In step 7, the arithmetic control unit Sp7 sends a signal (INQ) indicating that data is to be transmitted to the device number "1".
After transmitting to the ECRI of
Transmit the date setting data stored in T to ECR
1 is stored in the reception buffer register 33R.

At step 8, it is determined whether or not the Fm flag, which stores the presence of erroneous data, has been set. If the flag is normal, it has not been set, so the process proceeds to step 9.

In Step 9, it is determined whether the Fr flag indicating whether ECR1 has received the preset data is set or not. If not, wait until the Pr flag is set.

After the F1 flag is reset in step 10, the Fi flag is reset in step 11.

In the next step 12, it is determined whether or not the Fan flag that stores the existence of answer back data from ECRI is set. Since the data is stored in 14R, it is determined that the Fan flag is set and the process proceeds to the next step 13.

In step 13, it is determined whether or not the Fm flag is set, but if the data is transmitted normally, no cent is sent, so the process proceeds to the next step 14.

In step 14, the arithmetic control unit 11 reads out the answer back data stored in the buffer register 14T.

Then, in step 15, the arithmetic control unit 11
After resetting the flag, it is determined in step 16 whether the answer back data is not all rFJ, and in step 17 it is determined that it is not all "0".
In step 18, it is determined that the contents of the reception buffer register 14R are not an APP signal, and in step 19, it is determined that the dump mode is not in effect, and the process proceeds to the next step 20.

In step 20, it is determined that the device number is not specified, and in the next step 21, it is determined that the device number is not rl6], and in the next step 22
Proceed to.

In step 22, after adding the numerical value "1" to the device number and specifying the ECR2 with the next device number "2", the process returns to step 2 described above and repeats the operations from step 2 to step 22.

In addition, in Step 2 described above, if the pre-registered machine number indicating that the machine is stopped corresponds to the ECR of the device number to which data is to be transmitted, the data transmission operation to the ECR of the relevant device number is performed. The process proceeds to step 20 via the skip line s7, in which it is determined that the machine is not designated, and in step 21
In step 22, it is determined that the device number is not "16", and in step 22, the numerical value "1" is added to the device number to designate the next device number, and then the process returns to step 2.

Note that if it is determined in step 20 that the device number has been specified, or if the device number is
After sequentially transmitting preset data to R16 and registering settings, if it is determined in step 21 that the device number is "16", the process proceeds to step 23.

In step 23, it is determined whether a machine number to be skipped has been set.

If there is no machine number to be skipped, the EC that has successfully set and registered the date setting data in step 24
After printing and recording the machine number H, the Fap flag is reset in step 25, it is determined that the dump mode is not in step 26, it is determined that the X/Z key is not pressed in step 27, and step 2
After resetting the Fap flag in step 8, the series of preset operations in the normal case is completed.

As mentioned above, a normal device number (e.g. 1,
2,4~14,16), step 2~
22 operations are repeated for each ECR.

However, as shown in the time chart of Fig. 7, if there is an ECR with an abnormal device number (for example, 3, 15), the data transmission operation for that device number is interrupted, so that the ECR of the subsequent device number is data transmission operation becomes impossible.

Therefore, if there is any abnormality, a certain recovery processing action is performed depending on the type of abnormality, and if recovery is caused by this, the same action as in the above case is performed again, and even if the recovery processing is performed, the recovery process is performed. If not, skip to the ECR of the next device number to check the ECR that is not abnormal.
It is necessary to achieve data transmission operations with the CR.

Next, the operation when the ECR of a certain device number (for example, 3) is abnormal will be explained.

If there is any abnormality in the ECR, the interrupt permission signal is not given from the ECR in step 6 mentioned above, so Fa
The p flag remains reset.

Therefore, it is determined that the Pap flag is not set, and the process proceeds to the next step 29.

In step 29, it is determined whether or not the Fp flag indicating the power-off state of the CDT 10 is set (that is, whether there is an abnormality due to a power-off), but if the power to the CDTIO is normally supplied, the process proceeds to step 30. .

In step 30, it is determined whether the Fep flag is set, and it is determined whether the ECR of the device number to which data is to be transmitted is in a power-off state.

If the power is in the power-off state, proceed to step 20 described above via skip line sl, determine in step 20 that the device is not specified, determine in step 21 that the device number is not "16", and enter the device number. "1"
After specifying the ECR of the next device number by adding
Return to step 2.

On the other hand, if the power is not in the power-off state, the process advances to the next step 31.

F indicating waiting for 10 seconds in step 31
It is determined whether or not the w flag is set, and if the Fw flag is set, a timeout occurs in step 32 (
For example, 10 seconds have elapsed), and if the time has not passed, step 6, 29 ~
Repeat step 32.

When the time has elapsed, the Fs flag is set in step 33 to skip the ECR3 of the device number 3 to which data is to be transmitted, and the process then proceeds to step 20 via the skip line sl.

Also, if the flag indicating a 10 second wait is not set in step 31 (that is, if it has been reset).
, in step 34, it is determined whether the Fs flag is set.

If the Fs flag is not set, the process returns to step 6, and if the Fs flag is set, the process proceeds to step 20 via the skip line sl.

In this way, when there is no interrupt permission signal (APP signal), when the power of the ECH of the device number to which data is to be transmitted is cut off, or when the APP signal does not arrive even after a certain period of time, , or when there is a skip command, the ECR of the next device number (for example 4)
Skip to the destination.

Note that if it is determined in step 29 that the power to the CDT 10 is cut off, if the power is cut off while the brisset data is being transferred to the transmission buffer register 14T in step 5, a transfer will be missed, so the next After resetting the Fi flag in step 35, step 5
Return to

Further, if it is determined in step 8 that the Fm flag for storing the fact that a miss data has been transmitted is set, the process proceeds to step 36.

In step 36, the arithmetic control unit 11 subtracts "1" from the count value of the error counter ECT to count the number of times an error has occurred.

In step 3γ, it is determined whether the count value of the error counter ECT is “0” (that is, whether there have been three errors).

If the count value of the error counter is not 10'', proceed to step 35, reset the Fi flag in step 35, then return to step 5 described above, and perform steps 5 to 28.
Repeat the action.

If the count value of the error counter is rOJ (that is, if there have been three errors), in step 38, the error display lamp 27a is turned on and a buzzer is sounded to issue an alarm.

Thereafter, the process advances to step 24 described above, and the machine number corresponding to the ECR prior to the ECR of the device number in error is printed.

In addition, in step 12 described above, if there is no answer back data and the Fan flag is not set,
Proceed to step 39.

In step 39, it is determined whether the Fep flag is set, and it is determined whether the power of the ECR currently transmitting data is cut off.

If the power is cut off, the process advances to step 40.

In step 40, it is determined that the Fd flag indicating the dump mode is not set, and the process proceeds to step 20 described above via the skip line sl. Thereafter, the same operation as described above is performed, and the ECR of the next device number is data transmission.

On the other hand, in step 39, if the power to the ECR is not cut off, the process advances to step 41.

In step 41, it is determined whether the time is over,
If the time has not exceeded, step 12, 39,
Step 41 is repeated, and when the time is over, the process proceeds to step 42.

In step 42, it is determined that the Fd flag is not set, and in step 43, the error count E is determined.
The count value of CT is subtracted by "1" to count the occurrence of an error, and in the next step 44, the error counter E is
It is determined whether the CT count value is "0" (that is, the force for which an error has occurred three times).

If the count value of the error counter is "0", the process advances to step 38 described above, and if it is not "0", the process returns to step 5 via step 35, and the same operation as described above is performed.

Further, if it is determined in step 13 that the Fm flag is set due to the existence of miss data, the process proceeds to step 45.

In step 45, it is determined that the Fd flag is not set, and the process proceeds to step 43, where an error is displayed and then steps 24 to 28 are performed.

Further, in step 16 described above, if the answer back data stored in the receiving buffer register 14R is all rFJ, it is an error, so step 4
Proceed to step 6.

In step 46, the count value of the error counter ECT is subtracted by the numerical value "1", and in step 47, it is determined whether or not the count value of the error counter is "0".

If the number of errors is up to 2, Fap in step 48.
After resetting the flag, the process returns to step 6, and steps 6 to 28 are performed in the same manner as described above.

On the other hand, when the number of errors reaches 3, step 38 described above
The process proceeds to step 24, and after displaying an error message, the operations in steps 24 to 28 are performed.

In addition, in step 23 described above, if the ECR to which data has just been transmitted corresponds to the machine number to be skipped,
After resetting the Fw flag in step 49, "1" is added to the device number in step 50 to designate data transmission with the ECR of the next device number.

As described above, in the preset mode, as shown in Figure 7, ECRs with device numbers that have some kind of abnormality skip the preset operation, only normal ECRs are sequentially preset, and the machine number of the preset ECR is is printed and recorded.

Next, the case of data collection mode (dump mode), which is a feature of the present invention, will be explained.

In the dump mode, data is collected and stored in the read memory (first storage means) 12a (that is, data is collected in the inspection mode), and collected data is simultaneously stored in the read memory 12a and the thumb memory ( There are two types of modes: a case where the memory 34 of each ECR is cleared after cumulatively storing data in the second storage means) 12b (that is, a case where data is collected in the settlement mode).

First, to explain the operation when collecting data in inspection mode, as shown in Figure 3b above,
The mode selection switch 24 is set to inspection mode X and the type of data to be reported is specified.

If necessary, do the same as in the preset mode described above.
Perform the operations from step 0 to step 5.

In step 5, the arithmetic control unit 11 stores inspection mode information, key code information representing the register 14
Transfer it to T and store it.

If the Fap flag is set in step 6, it is determined in step 8 that the Fm flag is not set, and it is determined in step 9 that the Fr flag is set.

Furthermore, after resetting the Fi flag in step 10,
In step 11, set Fi.

In the next step 12, it is determined whether the Fan flag is set, and if it is normal, the ECR
Registration data based on the type code to be reported transmitted and given from T10 is stored in the sending buffer register 33, and is also transmitted and given to the receiving buffer register 14R.

Therefore, since the Fan flag is set in response to the transmission of registration data, the process advances to step 13.

If the Fm flag is not set in step 13, the process advances to step 14.

In step 14, the arithmetic control unit 11 reads the collected data from the ECR stored in the buffer register 14R.

After resetting the Fan flag in step 15,
In step 16, it is determined that the data is not all "F", in step 1γ, it is determined that it is not all "0", and in step 18, it is determined that it is not APP data, and the process proceeds to the next step 19.

In step 19, it is determined whether or not the Fd flag is set. Since this Fd flag was set when the dump mode was selected, it is determined that the Fd flag is set (that is, the dump mode is in effect). After making a determination, the process proceeds to step 51.

In step 51, if there is no abnormality, it is determined that the Fs flag, which instructs skipping, is not set, and the process proceeds to step 52.

In step 52, the arithmetic control unit 11 stores the collected data stored in the receiving buffer register 14R in the corresponding data type storage area of the read memory 12a.

Then, in step 53, it is determined whether or not it is the end of the data, and the step
~19. Repeat operations 51 and 52.

When the collected data is stored in the read memory 20 to the end, it is determined in step 54 whether or not the Fs flag is set.

At this time, step 3 in the preset mode mentioned above.
As explained in Section 3 or as explained in Step 66 below, if the Fs flag is set even in the dump mode, the process proceeds to Step 35 after resetting the Fs flag in Step 55, but if the Fs flag is not set. If not, proceed to step 20.

Then, in step 20, it is determined that no device number is specified, and in step 21, the device number is "
16", in the next step 22, add the numerical value "1" to the device number and write the ECR of the next device number.
Specify.

Similarly, the same operation is repeated for each ECR of each device number, and the collected data of the specified data code registered in each ECR is collected and stored in the read memory 12a.

Then, in step 21 described above, when it is determined that the device number is "16" and it is determined that the data collection operation for all devices has been completed, the process proceeds to step 23.

If it is determined in step 23 that there is no machine number to be skipped, the machine number for which data has been collected is printed in step 24, and then in step 25
The Fap flag is reset at

In step 26, it is determined that the mode is dump mode, and in step 58, it is determined that the mode is not settlement mode Z, and the process proceeds to step 59.

In step 59, the printer 25 prints and records the collected data to create a report (for example, a daily report).

Then, in the next step 60, it is determined that the mode is not the payment mode, and after the Fap flag is reset in step 28, the series of operations for collecting data in the inspection mode is completed.

Next, the operation when collecting data in the payment mode will be explained.

After setting the mode selection switch 24 to settlement mode Z and specifying the type of data to be reported, as shown in FIG. 3C, the secret number is input and the X/Z key is pressed.

At this time, if the secret number has been set in advance, the following operations are started.

That is, steps 0, 1 to 19, and step 51 are performed in the same manner as the operation when collecting data in the inspection mode described above.
-54, after repeating the operations of steps 20-22, the operations of steps 23-26 are performed.

After determining in step 26 that the mode is dump mode, in step 58 it is determined that the mode is settlement mode Z, and the process proceeds to step 61.

In step 61, after resetting the Fd flag, the arithmetic control unit 11 causes the buffer register BF to store a clear code that instructs to clear the memory 34 included in the ECH.

Then, the operations from steps 0 to 22 described above are repeated to transmit a clear code for commanding the storage information of the memory 34 to each ECR, and clear the contents of the memory 34 of each ECR.

The clearing operation for all platforms is performed, and step 21 described above is performed.
When it is determined that the device number is 116'', the process proceeds to the next step 23.

If the machine signal to be skipped is not registered in step 23, the machine number of the ECH whose memory 34 has been cleared is printed in step 24.

After resetting the Fap flag 25 in step 25, it is determined in step 26 that the Fd flag is set, and the process proceeds to step 27.

In step 27, it is determined that the X/Z key 23b is pressed, and the process proceeds to step 59.

After creating a report based on the collected data in step 59, in the next step 60, it is determined that the payment mode is in effect, and the process proceeds to step 62.

In step 62, the arithmetic control unit 11
The type-specific collected data stored in the read memory 12a is added to the type-specific collected data previously stored in 2b, and the type-specific data is cumulatively stored in the thumb memory 12b.

After resetting the Fap flag in step 28, the series of operations for collecting data in the payment mode is completed.

Note that in the above description of data collection in the inspection mode or payment mode, the description was made assuming a normal case, but if there is any abnormality, the following procedure will be performed.

That is, if it is determined in step 6 that the Fap flag is not set, p
If it is determined that the m flag is set, if all rFJ is determined in step 16, if all "0" is determined in step 1γ, or if it is determined that it is APP data in step 18, the operation is Since the operation is similar to that in the preset mode, detailed explanation will be omitted.

If the Fan flag is reset in step 12 and it is determined that there is no answer back data, the process proceeds to step 39.

In step 39, it is determined whether a flag Fep for storing the ECH power-off state is set, and if power is being supplied normally, the process proceeds to step 41.

In step 41, it is determined whether the time is over,
If the time is not over, steps 12, 39, and 41 are repeated, and if the time is over, the process advances to step 42.

Then, in step 42, it is determined that the Fd flag is set, and in the next step 63, the Fd flag is reset, and then the process proceeds to step 38 described above.

Further, if it is determined in step 39 that the Fep flag is set, the process proceeds to step 40.

In step 40, it is determined that the dump mode is in effect, in the next step 64, it is determined that the Fep flag is set, and in step 65, the system waits until the time is over, and if the time is over, step 63
After resetting the Fd flag, the process advances to step 38.

Note that when the ECR returns from the power-off state to the power supply state during standby for a certain period of time in step 65, the Fep flag is reset, so it is determined in step 64 that the Fep flag has been reset, and step 66 Proceed to.

After setting the Fs flag to issue a skip command in step 66, the Fi flag is reset in step 35, and the process returns to step 5.

In this way, operations are performed in abnormal cases.

As described above, this embodiment provides the following unique effects.

In other words, the data collection operation mode is performed in two modes (inspection mode and payment mode), and in the inspection mode, the collected data is stored by type only in the read memory, and reports can be created based on the stored information. Reports can be created quickly and easily not only after the store has closed, but also even while the store is open, and sales data can be obtained at any time.

Also, when collecting data in payment mode, the collected data by type is stored cumulatively in the thumb memory.
You can easily create sales data for a certain period of time (for example, weekly reports, monthly reports, etc.).

Furthermore, when data is collected in payment mode, only a specific person can operate the system, which prevents ECH registered data from being cleared by mistake.

Furthermore, when collecting registered data from multiple ECRs, a machine with some kind of abnormality will be skipped and the process will proceed to the next machine, so an abnormality in one machine will not cause the data collection operation of other machines to stop. It can be prevented.

As described above, according to the present invention, registered data of multiple ECRs can be collected quickly, inexpensively, and efficiently, and data can be selectively collected by specifying a desired ECR among multiple ECHs. Furthermore, a data collection control system for a plurality of ECRs can be obtained that allows easy creation of materials for different periods, such as daily reports, weekly reports, and monthly reports.
