Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a management system for a plurality of cash registers.

<Example of Conventional Technology> As an example of a management system for a plurality of cash registers, a plurality of cash registers are connected to a central management device, and a flag for storing data transmission status between the cash registers and the above-mentioned data output means for outputting a transmission status, input means for operating the data output means, and transmission control means for transmitting data between the cash register and changing a flag indicating the data transmission status. Japanese Patent Application Laid-Open No. 1983-1997 discloses a device in which the central management device is provided with a cash register, and data is transmitted between the central management device and the cash register.
It is described in Publication No. 44455.

In the prior art described in this publication, a flag that stores whether or not power is being supplied to the cash register according to data from the cash register;
The data transmission status can be temporarily checked using a flag that stores whether an error occurred during data transmission to and from the cash register, and a flag that stores whether data transmission to and from the cash register was completed normally. In addition to printing out errors based on the flag storage state, the cache register that did not complete data transmission normally is skipped and data is transmitted to the next cache register. ing.

<Problems with the prior art> According to this prior art, for example, if the central management unit accesses a certain cache register while the power to the cache register is not yet turned on, the power is turned off and the cache register is turned off. The data will be skipped and no data will be transmitted. After that, the process when the power is turned on is as follows.
Although not disclosed, it can be inferred that data transmission is performed in the process of sequentially accessing the first cache register again to confirm that the power has been turned on. This is because each flag is used commonly for all cache registers, and when used for the next cache register, it no longer retains the set/reset state for the previous cache register. be. As described above, according to the prior art, the central management unit sequentially accesses all cache registers when transmitting data, so it takes less time to transmit data to each predetermined cache register. The disadvantage was that it took a lot of time.

<Technical Problem> The present invention provides management of multiple cash registers that can minimize unnecessary operations and shorten transmission time when transmitting data between multiple cash registers and a central management device. The purpose is to provide a system.

<Means for Solving the Problems> The present invention connects a plurality of cash registers to a central management device, and includes a memory for storing data transmission status with the cash registers and outputting the data transmission status. a data output means for
The central management device is provided with an input means for operating the data output means, and a transmission control means for transmitting data to and from the cash register and changing a flag indicating the data transmission status. In a management system for a plurality of cash registers in which data is transmitted between devices and cash registers, the memory stores information about the cash registers corresponding to terminal codes assigned to each of the cash registers. Indicates whether power is being supplied to the power register.
Indicates whether an error occurred during data transmission between the OFF flag and its cache register.
It has an ERR flag and an OK flag that indicates whether data transmission with the cash register has ended normally, and stores the data transmission status using the OFF flag, ERR flag, OK flag, etc. According to the data transmission status stored in the memory, the transmission control means sequentially and cyclically searches for the cache registers for which data transmission has not been normally completed, and performs the data transmission. When the transmission is completed, the OK flag is changed to a transmission completed state, and the data output means changes the data output means to the OFF flag, the ERR flag, the OK flag, etc. in accordance with the terminal code based on the operation of the input means. It is characterized by outputting the indicated data transmission status.

<Operation> When performing data transmission with each cash register, the transmission control means refers to the data transmission status stored in the memory in the form of a flag. Since the data transmission status is stored in the memory in correspondence with the terminal code assigned to each cache register, the transmission control means refers to the data transmission status corresponding to the cache register that performs data transmission. , determines whether data transmission has been completed normally or not, and if it is found that data transmission has not been completed normally, data transmission is performed, and when data transmission has been completed normally, the OK flag is changed to the transmission completed state. . If the data transmission has ended or is found to have ended normally,
Similar processing is performed for the next cache register. Once the above processing has been performed for all cache registers, the process returns to the first cache register and the same processing is performed cyclically in sequence.

When the input means is operated and a transmission status report is instructed, the data output means outputs the data transmission status indicated by an OFF flag, an ERR flag, an OK flag, etc. corresponding to the terminal code. This allows operators, administrators, and the like to check the data transmission status.

<Effects of the Invention> According to the present invention, when transmitting data between a plurality of cash registers and a central management device, the memory storing the transmission status in the form of a flag corresponding to each cash register is referred to. Since data transmission is performed by sequentially cyclically searching for cache registers for which data transmission has not been completed while skipping cache registers for which data transmission has been completed normally, unnecessary operations are reduced and cache registers are The register search time is shortened, and the overall transmission time can be shortened.

Further, according to the present invention, since the transmission status is output based on the operation of the input means, it can be output all at once, and data transmission to a cache register capable of data transmission can be performed early and quickly. Can be done. Furthermore, output is performed only once for each operation of the input means to one cash register, and is not performed in duplicate or triplicate, but is output collectively to all cash registers. It is performed in a ivy shape, so
Operators and managers can easily check the data transmission status.

<Example> Fig. 1 shows an overall block diagram of a consolidator as an example of a central management device, in which 1 is a keyboard as an example of an input means, 2 is a display section, 3 is a memory, and 4 is an example of an output means. , 5 is an arithmetic processing unit, and 6 is a transmission unit. 1st
The diagram shows the configuration of each ECR (electronic cash register).
This configuration is also common to the terminals, and the consolidator is connected to each ECR terminal via the transmission section 6. FIG. 2 shows a detailed layout of the keyboard 1, showing a mode setting switch 11, various function keys 12, numerical keys 13, and transaction keys 14, respectively. Figure 3 shows display section 2.
This is a detailed diagram of the multi-digit (10-digit) numerical display section 2.
1 shows the function display section 22 that is displayed as 1. FIG. 4 shows the layout of the memory 3, which is provided with a connection state table including a register number setting area and a connection flag setting area for each terminal address. Each terminal address (terminal ECR setting position) does not necessarily have the same
ECR terminals are not necessarily installed permanently. For example, depending on the store, the layout of the sales floor may change depending on the season, or a new sales floor may be set up.
There are many cases where the sales floor has to be reduced. that time,
Terminal installed at each terminal address
Change the ECR or abolish it due to a reduction in the sales floor. All 0's are stored in the terminal address where the terminal ECR has been abolished, and the connection flag is also set to 0. If the connection flag is 0,
The corresponding terminal address has a terminal
Indicates that the ECR is not present or is present but not connected to the consolidator. In addition,
The connection state table is preset by the keyboard 1. The transmission status of each terminal ECR with the consolidator is set in the transmission status flag. A transmission status flag is provided for each terminal address, and consists of an untransmitted flag, an OFF flag, an error (ERR) flag, and an OK flag. The untransmitted flag is set corresponding to the terminal ECR for which data transmission has not been completed.
The OFF flag is set corresponding to a terminal ECR determined to be powered off, and the error flag is set corresponding to a terminal ECR determined to have an error in data transmission.
Also, the OK flag is set corresponding to the terminal ECR for which data transmission has been completed. Note that when the OK flag is set, the untransmitted flag is reset. The memory 3 further includes a 1-byte memory area 31 for storing the number of untransmitted terminal ECRs or the number of completed transmissions. The contents stored in the memory area 31 are added or subtracted each time the transmission of each terminal ECR is completed.

Next, an example of the operation will be explained with reference to the flowchart shown in FIG. Consolidator and each terminal
Before transmitting data with the ECR, first set the mode setting switch 11 of the consolidator to the setting mode. When the function key PLU is operated, all transmission status flags are cleared.
The settings of the connection flag are then transferred to the untransmitted flag. That is, the untransmitted flag is set only for the terminal address whose connection flag is set. The total number of set untransmitted flags is stored in the memory area 31. In other words, in this embodiment, the memory area 31 is used for untransmitted terminals.
Memorize the number of ECRs. The contents of the memory area 31 are displayed on the display section 2. FIG. 3 shows that 13 units remain without transmission.

If a transmission status report is not required, immediately check the non-transmission flag and start searching for non-transmission terminals. The search for untransmitted terminals is performed in the order of terminal addresses,
The consolidator sequentially transmits data to the terminal ECR whose untransmitted flag is set.
In the example in Figure 4, the ECR for terminal address number 1
After data transmission is performed, the ECR of terminal address No. 3 is searched and data transmission is performed.

When the data transmission is completed, it is checked whether there were any errors, and if an error occurred in the transmission, the error flag of the corresponding terminal address is set. If no transmission occurs at all, it is determined that the terminal ECR has not been powered on, and the corresponding OFF flag is set. When the error flag or OFF flag is set, the untransmitted flag also remains set, leaving an opportunity to be searched again after one round of terminal addresses.

When it is determined that data transmission is OK, the OK flag of the corresponding terminal address is set and the untransmitted flag is reset. The contents of the memory area 31 are subtracted by 1, and the subtraction result is displayed on the display section 2 as described above. In this way, the search for untransmitted terminals ECR, data transmission, and display of the number of untransmitted terminals are repeated until the displayed data becomes 0. Incidentally, although the displayed number of untransmitted devices gradually decreases, it may reach a certain value and stop changing. If the display data does not change forever like this, it becomes necessary to understand the transmission situation in more detail. Therefore, it is determined that a more detailed report on the transmission status is required, and the function key call is operated. When this key is operated, the contents of the transmission status flag in the memory 3 are printed by the printer 4 together with the register number. FIG. 6 shows an example of a transmission status report.
