Embodiment FIG. 1 is a block diagram showing the configuration of a data transmission device 1o constituting a sales management system according to an embodiment of the present invention.

Such a data transmission device 1o includes a host computer 1, which is installed at the head office of an affiliated store, for example, and is a central control device, and an electronic cash register installed at each store, which is connected to the host computer 1 through an online communication line. c1 to Cn (hereinafter collectively referred to as electronic cash register C) communicate with each other.

The electronic cash register C includes a processing circuit 4, and the processing circuit 4 transmits and receives data to and from the host computer 1 via the transmitting/receiving circuit 3 and the interface 2. A read-only memory 5 in which 10 grams and the like for performing so-called cash register operations are stored is connected to a plurality of files 6a to 6d (hereinafter referred to collectively as the isle 6) realized by a random access memory or the like. Ru. Further, a key manual section 7 for performing cash register operations and a printer section 8 for printing on so-called receipts are controlled by the processing circuit 4.

In such an electronic cash register C, predetermined commands are transmitted from the host computer 1. Electronic cash register C executes an operation corresponding to this command. In addition, the electronic cash register C has two cases: one has handsets M1 to Mm (electronic cash register C1 in Figure 1), and the other has no handset (electronic cash register C2 in Figure 1). There is.

FIG. 2 is a diagram showing the flow of signals when data is transmitted from the host computer 1 to the electronic cash register C. A write request signal WFI is transmitted from the host computer 1 to the electronic cash register C, and upon receiving the write request signal WF1, the electronic cash register C secures an area for storing the command from the host computer 1. and becomes ready to receive. The host computer 1 subsequently sends commands as described below. This command includes information regarding the operation that the electronic cash register C should perform.

When the host computer 1 finishes sending such a command, a signal RBI, which is an end signal, is sent to the electronic cash register C. Electronic cash register C uses this signal RB1.
When the host computer 1 receives the command, it transmits a signal RB2, which is also an end signal, to the host computer 1 to notify the host computer 1 of the end of receiving the command.

In this way, a command is transmitted from the host computer 1, and the electronic cash register C executes an operation corresponding to this command.

No. 351 is a diagram showing the structure of a command sent from the host computer 1 to the electronic cash register C. A command is composed of a job number that specifies the operation to be executed, various parameters, and dummy data to match the unit data capacity at the time of transmission. , perform the action corresponding to this command.

For example, when the job number is r500J, the electronic cash register C has slave units M1 to Mm (generally referred to as M when necessary) (see Figure 1.
), a so-called store opening process is executed, such as transmitting setting data, program data, etc. to the slave device M and making the slave fiM ready for registration. Also, the job number is r501
At the time of J, the electronic cash register C causes each handset M to transmit registration data, prohibits operation of each handset M, that is, puts the power supply in a state of cut-off, and performs a so-called closing process.

As for the data transfer operation from the electronic cash register C to its slave machine M, for example, when the job number is "850", the key function assignment of each slave machine M is such that the data is transferred to each slave machine M1 to
Mm, and set the key functions of each handset M1 to Mm.

In connection with the inspection/settlement operation, for example, operations corresponding to job numbers as shown in Table 1 below can be executed by remote control.

Table 1 In Table 1, "Y" in the job number represents 1 or 2, and when Y=1, the total for each day (daily total), Y=
2 indicates the total (period hand) for each period, for example, for each month.

For example, when the job number is rYOOJ, the sales of each department, the total sales of all departments, the total amount of discounts in all transactions, the number and amount of returned products, and the amount of money when the registration is corrected due to an operator's registration error. The data for all items, such as the quantity or the number of exchanges, is printed for each item, and if settlement is specified by a parameter, these numerical values are reset after printing.

When the job number is rY30J, data about the above-mentioned items excluding sales of each department (hereinafter referred to as transaction items) is printed.

When the electronic cash register C has a slave M, the above processing operation is performed on the total data of the data in the electronic cash register C and the data of the slave 8NM of the electronic cash register C.

Also, if the job number is rYo 1 and you specify the electronic cash register C or some of its slave machines M with parameters, then the electronic cash register C or the designated slave machine M
It is possible to print the data for all the above items, which is the sum of the data. Furthermore, set the job number to rY30J and use the electronic cash register C or its slave machine M as a parameter.
By specifying , it is possible to print data related to the above-mentioned transaction item, which is the sum of data for the electronic cash register C or the specified child machine M.

Figure 4 shows the host computer 1 of the electronic cash register C.
2 is a flowchart for explaining operations corresponding to commands from. At step n1, the electronic cash register C receives data from the host computer 1. In step n2, if this data is a command sent from the host computer in the format described above, the process moves to step n3. If the received data is not a command, the process moves to step n6 and other processing is performed.

In step n3, the job number and parameters included in the command are set in the electronic cash register C,
Further, an end code, which will be described later, is set to "not activated".

In step n4, execution of the operation corresponding to the job number, ie, the operation such as inspection/accounting, is started. When such an operation is completed, an end code, which will be described later, is set to "normal end" in step n5.

When such remote control is performed, the host computer 1r! The IA needs to confirm whether the electronic cash register C is operating normally. For such confirmation, the host computer 1 requests the electronic cash register C to send termination information.

FIG. 5 is a diagram showing the flow of signals when such termination information is transmitted. The host computer 1 transmits a read request signal RF for reading out the termination information to the electronic cash register nC. After this, a termination signal RB3 is transmitted. The electronic cash register C sends a write request signal WFI before transmitting the termination information, and the host computer 1
The side must secure a storage area for the received data. Thereafter, the electronic cash register C transmits termination information having the configuration described below to the host computer 1. When the transmission of the termination information is finished, a termination signal RB4 is transmitted.

When the host computer 1 causes the electronic cash register C to continue to perform the next operation by remote control, it transmits the write request signal WFI described above.

When the transmission with the electronic cash register C is finished, an end signal RB5 is sent to the electronic cash register C.

Figure 6 shows electronic cash register C to host computer 1.
FIG. 3 is a diagram showing the structure of termination information transmitted to the computer. The end information includes a job number, an end code, and dummy data.

In the termination information, the job number and dummy data are meaningless; only the termination code has meaning.

An example of an exit code is shown in Table 2.

Table 2 The end code rooooJ is
This means that the operation corresponding to the command sent from (hereinafter referred to as command operation) has completed normally.

The exit code "0010" means that the command operation has not yet been executed or is currently being executed.

End code ro020. means that when electronic cash register C has handset M, the command operation was not executed because a communication error with handset M occurred.

The end code ro030J means that the command operation for the payment process or the store opening process could not be executed because the electronic cash register C was performing the store opening process.

End code ro040. This means that the electronic cash register C is in the process of closing the store, so the command operation for closing the store could not be executed.

The end code "ro050" means that when the electronic cash register C has a slave device M, the command operation for the store opening process could not be executed because the electronic cash register C was communicating with the slave device M.

The end code r0060J means an error in the job number of the command sent from the host computer 1.

End code ro070. means that the product data is not stored because no product data has been input, and a command operation such as transferring product data cannot be executed.

The end code rooso indicates that when an operator is predetermined for the electronic cash register C and the operator code is defined, the command operation cannot be executed because the operator code is undefined. It means it couldn't be done.

The end code "0090" means that the slave units M1 to Mm are in the process of registering and cannot perform command operations such as transfer to the slave units M1 to Mm.

The end command r0100J means that the parameters of the command from the host computer 1 are abnormal.

In this way, the host computer 1 can know the result, such as whether the operation of the electronic cash register C corresponding to the previously transmitted command was completed normally or the reason why the operation could not be executed.

FIG. 7 is a flowchart for explaining the operation of the electronic cash register C when transmitting termination information.

Data from the host computer 1 is received in step m1, and the electronic cash register C decodes this data. In step m2, it is determined whether this data is the read request signal RF, and if it is not the end code read request signal RF, the process moves to step m5 to execute other processing. If the data is the end code read request signal RF, the process moves to step m3, and the electronic cash register C reads out the set end code.

As described above in step m4, the termination information including this termination code is transmitted to the host computer 1.

As described above, in this embodiment, by transmitting a command from the host computer 1 to the electronic cash register C, the electronic cash register C can be remotely controlled. Furthermore, the electronic cash register C stores an end code for the operation executed by such remote control, and the host computer 1 determines whether the operation corresponding to the transmitted command is normal in the electronic cash register C. You can check whether it was done or not.

Effects As explained above, according to the present invention, the central control device and the
The one or more electronic cash registers are connected via a communication line, and the electronic cash register receives a predetermined command from the central controller and performs an operation corresponding to the command. Therefore, it is possible to remotely control one or more electronic cash registers from the central control device, and it is possible to save labor and improve the operability of the data transmission device.
