Abstract

PURPOSE:To add functions of electronic cash registers and to vary and set accompanying parameter settings without altering an on-line program by composing a command of key codes corresponding to a series of key operations and sending the command. CONSTITUTION:The command consists of key codes of a series of key operations at the time of the manual operation of electronic cash registers C1-Cn and dummy data for matching the unit data capacity at the time of transmission. Then when a host computer 1 operates the register C1 previously, the previously generated command is sent and the register C1 is put in operation corresponding to the command. Namely, the register C1 reads out the key codes of the sent command in order and performs key processing corresponding to each key code at each time, so it operates equivalently to manual operation even in remote operation. Consequently, functions are added to the respective cash registers C1-Cn and the settings of parameters accompanying the functions are varied and added without altering the on-line program.

A sales management system that sends data representing the unit price of each product, department code, etc. from the central processing center to the electronic cash register at each store, and centrally manages sales for all stores at the host computer at the head office or the central processing center. is being implemented.

In such a sales management system, a master machine and a slave machine of an electronic cash register may be installed in each store. In this case, the base machine of the electronic cash register has the function of performing inspection and payment, data sent from the host computer, or data set by the base machine of the electronic cash register, which is installed in multiple locations in each store. It has functions such as transferring data to slave devices of electronic cash registers, and executing processing for opening and closing stores.

In addition to manual operation by an operator, the functions of the base unit can be swept remotely by commands from a host computer. At this time, a predetermined command, which will be described later, is transmitted from the host computer, and the electronic cash register executes an operation corresponding to the command.

As shown in FIG. 6, the command is composed of a job number specifying the operation to be executed, various parameters, and dummy data for matching the unit data capacity at the time of transmission.

Therefore, when the electronic cash register receives the command, it sets the job number and parameters using an online program, and then moves to the processing program corresponding to the job number to execute the job.

<Problems to be Solved by the Invention> In the conventional remote control of an electronic cash register from a central control device, the electronic cash register processes commands sent from a host computer using an online program, and then performs a predetermined process. The work was performed based on the processing program.

Therefore, for example, adding the function of an electronic cash register,
When adding or changing parameter settings in a command, the online program also had to be changed each time.

An object of the present invention is to provide a sales management system that can add functions to an electronic cash register and change or add parameter settings associated with the functions without changing the online program.

<Means for Solving the Problems> The present invention includes: a central control device; and one or more electronic cash registers connected to the central control device via a communication line; A series of steps when sending a command to an electronic cash register to remotely control the electronic cash register to perform a predetermined task, and having the electronic cash register process the task manually. This sales management system is characterized in that a key code corresponding to a key operation is configured as the command, and the command is sent to the electronic cash register to cause it to execute a predetermined task by remote control.

<Operation> According to the present invention, in the remote control by the central control device of one or more electronic cash registers connected to the central control device via a communication line, the electronic cash register receives the information transmitted from the central control device. The key codes in the received commands are read out in order and the key processing corresponding to the key code is performed each time, so the operation is equivalent to manual operation even though it is remote controlled.

Therefore, it is possible to add functions to the electronic cash register and to change or add parameters associated with the functions without changing the online program.

<Embodiment> FIG. 1 is a block diagram showing the configuration of a data transmission device 10 constituting a sales management system according to an embodiment of the present invention.

Such a data transmission device 10 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. 01 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 . The processing circuit 4 also includes a read-only memory 5 in which programs for performing so-called cash register operations in the electronic cash register C are stored, and a plurality of files 6a to 6d (hereinafter referred to as (collectively referred to as file 6) are connected. Further, a key manual section 7 for performing cashier 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, a predetermined command is transmitted from the host computer 1.The electronic cash register C executes an operation corresponding to this command. There are slave units M1 to Mm.
(Electronic cash register CI in Figure 1) and without a slave unit (Electronic cash register C2 in Figure 1). FIG. 2 is a diagram showing the flow of signals when data is transmitted from the host computer I to the electronic cash register C. From the host computer 1, a write request signal WFI is sent.
is transmitted to the electronic cash register C, and the electronic cash register C
When the write request signal WFI is received, an area for storing commands from the host computer 1 is secured and the host computer 1 becomes ready for reception. From the host computer,
Subsequently, commands as described below are sent. 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 RBI
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 I, and the electronic cash register C executes an operation corresponding to this command.

Figure 3 shows the flow from the host computer L to the electronic cash register C.
FIG. The command is composed of a key code that encodes a series of key operations when manually operating the electronic cash register, and dummy data for matching the unit data capacity at the time of transmission.
