Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data transfer device for brand information processing, and more particularly to a data transfer device capable of transferring the edited result of the previous closing price information to a terminal device without delay and the brand information in the data transfer device. Regarding processing method.

[0002]

2. Description of the Related Art A data transfer device for stock information processing transfers data received from a host computer of an information providing company to a data display terminal, and at the time of transfer, edit processing such as information deletion of delisted stocks is performed. It is something to do.

The data received from the host computer of the information provider is managed by a serial number called a stock number, and when a stock is delisted,
The brand number may be used as a number pointing to another brand from the 11th day onward.

In this way, when the stock corresponding to the stock number is changed, unless the edited contents of the delisted stock are deleted from the contents of the data editing table, the quote information is used by using the information of the old stock. Therefore, data different from the actual data may be transmitted to the data display terminal.

On the other hand, since the securities information is received via the one-way communication line, the stock information may not be normally received due to a line failure or the like. In order to distinguish such an obstacle from the case of delisting, data is usually retained for 10 days, and only the stock that is not updated for 11 days or more is considered to be delisted and the data is deleted.

Next, a conventional data transfer device is shown in FIG.
Use to explain. FIG. 5 is a configuration block diagram of a conventional data transfer device. As shown in FIG. 5, the conventional data transfer device includes a line control unit 1, a main control unit 2 having a memory 21, and an FD 3 as an external storage device. In addition, the line control unit 1 includes a reception buffer 11,
It has a configuration including a transmission buffer 12.

Next, each part of the conventional data transfer device will be specifically described. The line control unit 1 receives securities information (stock price data, etc.) received from an information providing host via a one-way communication line.
Is passed to the main control unit 2 via the reception buffer 11, and the securities information (edited stock price data, etc.) edited by the main control unit 2 is received by the transmission buffer 12 to receive the securities information via the one-way communication line. Is transmitted to the data display terminal for displaying.

The main control unit 2 receives the securities information in the reception buffer 1
1), based on the edited contents expanded from the FD 3 on the memory 21, it is determined whether or not the stock data itself is suppressed or a part of the data such as quote information is suppressed, edited, and edited in the transmission buffer 12. This is to pass the securities information that was created. The FD 3 stores a program for performing an editing process and also stores a data editing table having edited securities information.

Note that one day's transmission of securities information from the data transfer device to the data display terminal is "terminal startup information",
"1st issue information", "previous day closing price information", "2nd issue information", "previous listing information", "3rd issue information",
It will be done in the order of "list information". Here, "stock information"
Includes a brand number, a brand code, a brand name, and the like.

The "previous day's closing price information" includes the stock number and
The exchange name and the closing price on the previous day, etc. are included. "Foreign exchange information" is the issue number, exchange name and exchange transaction data, and "reverse information" is the issue number and exchange name. Includes back-end transaction data and, respectively.

As shown in FIG. 6, the data transfer processing of the conventional data transfer device is performed according to the type of information received.
The terminal start-up information editing process, the brand information updating process, the previous day's closing price information editing process, and the previous / post-place information editing process are performed, and the edited data is transmitted to the data display terminal. 6. FIG. 6 is a flowchart showing the data transfer processing of the conventional data transfer device.

Specifically, the line control unit 1 receives the securities information (stock price data, etc.) via the one-way communication line (S3).
1) Pass it to the main control unit 2. The main control unit 2 determines the type of the received information (S32), and if the received information is "terminal startup information", edits the terminal startup information (S33), and the received information is "brand information". If so, the issue information is updated (S34), and if the received information is "previous day's closing price information", the previous day's closing price information is edited (S3).
5) If the received information is "previous / rear information", the front / rear information is edited (S36). And the line control unit 1
Sends the edited securities information via the one-way communication line (S37).

The flow of processing in the conventional data transfer apparatus and the stock information processing method therefor will be described with reference to FIGS. 7, 8, 9, and 10. FIG. 7 is a flowchart of a conventional terminal startup information editing process, FIG. 8 is a flowchart of a conventional brand information updating process, and FIG. 9 is a flowchart of a conventional previous-day closing price information editing process. Further, FIG. 10 is a flow chart of the conventional front / rear information editing process.

In FIG. 7, when the main controller 2 receives the "terminal startup information", it updates the device date (S4).
1), the data editing table corresponding to the brand number held by the FD 3 is developed on the memory 21 (S42).
The contents of the data editing table are the data suppression information,
It consists of quote restraint information, brand information update date, and the like.

In FIG. 8, when the main controller 2 receives the "brand information", it updates the contents of the data editing table corresponding to the brand number of the received brand (S5).
1). After receiving all the brand information, it is judged whether or not the brand information is the second and subsequent normal reception (S52), and if the second and subsequent normal reception, the FD3 is selected. The contents of the updated data editing table are saved (S53), and the process ends. In addition, in the process S52, when the received brand information is the first brand information,
Alternatively, if the reception is not normal even for the second and subsequent times, the contents of the data editing table are not stored in the FD 3 and the process ends.

In FIG. 9, when the main control unit 2 receives the "previous day closing price information", the main control unit 2 confirms whether or not an unupdated check (hereinafter, unupdated check) of the brand information update date in the data editing table is performed. (S61) If the unupdated check has been performed, from the data editing table,
The editing information such as the data indicative depressing information corresponding to the stock number of the received closing price information on the previous day is taken out and edited (S6).
6). Whether or not the unupdated check is performed in the process S61 is confirmed by using a flag or the like, and the issue number first received at the time of receiving the closing price information on the previous day is not updated in the data editing table in the processes S62 to S65 described later. After checking once, a flag is set so that no unupdated check is performed for the subsequent issue numbers.

If the unupdated check is not performed, the issue information update dates are checked in order from the beginning of the data editing table (S62), and it is checked whether there is an issue whose date has not been updated for 11 days or more. Yes (S6
3). If there is a brand whose date has not been updated for more than 11 days, edit the data of the relevant brand by
It is deleted from the data editing table (S64). Also,
In the process S63, if there is no brand whose date has not been updated for 11 days or more, the process proceeds to the process S65.

Then, it is determined whether or not the unupdated check is completed for all the contents (brand number) of the data editing table (S65). If the check has not been completed, the operations in and after step S62 are repeated for the next brand number. If the check is completed in the process S65, the data of the previous day's closing price information, the indicative price information, the suppression information, etc. are edited based on the updated data editing table (S66).

In FIG. 10, when the main control unit 2 receives the front / rear trading information, it extracts the edit information corresponding to the brand number of the front / rear trading information from the updated data editing table, and the data, the indicative information, and the suppression Editing processing of information and the like is performed (S71).

[0020]

However, in the above-mentioned conventional data transfer apparatus and the stock information processing method in the conventional data transfer apparatus, when the closing price information on the previous day is received, the stock information corresponding to the stock number is updated by checking the stock information update date. However, there is a problem that a delay occurs in the transmission of the previous day's closing price information to the data display terminal because the editing process of the previous day's closing price information is performed.

Will be updated, without leaving unnecessary stock information in the data edit table, without delaying the editing data of the closing price information on the previous day,
It can be transmitted to the data display terminal.

FIG. 1 shows a data transfer device according to the present invention.
Use to explain. FIG. 1 is a configuration block diagram of a data transfer device according to the present invention. It should be noted that parts having the same configuration as in FIG. The data transfer device of the present invention (this device) is composed of a line control unit 1, a main control unit 2'having a memory 21, and an FD 3 as an external storage means, as in the conventional data transfer device. As a characteristic part of the apparatus, the main control unit 2'includes two tables in the memory 21, a data editing table 21a and a normal stock information updating table 21b. The line control unit 1 is composed of a reception buffer 11 and a transmission buffer 12 as in the conventional line control unit 1.

Next, each part of the present apparatus will be specifically described.
First, the line control unit 1 receives securities information (stock price data, etc.) received from a host computer of an information providing company via a one-way communication line to a main control unit 2'via a reception buffer 11 as in the conventional case. The securities information (edited stock price data, etc.) that has been handed over and edited by the main control unit 2'is received by the sending buffer 12 and sent to the data display terminal via the one-way communication line.

The main control section 2 ', which is a characteristic part of the present apparatus,
When the terminal start-up information is received, the data content of the normal stock information update table 21b is cleared, the data editing table 21a is read from the FD 3 and expanded on the memory 21. In this case, the data editing table 21a is in a state in which the stock number and the data corresponding to the conventional stock are stored. Then, when the brand information is received, the contents of the edited data are set in the data portion of the brand number corresponding to the brand name in both tables, and the contents of the normal brand information updating table 21b are further set when the brand information is normally received after the second time. Is overwritten on the data editing table 21a. As a result, the data editing table 21
Since the data corresponding to the brand number of the brand that is not updated in a will be set to clear, it is possible to delete the conventional data relating to the old brand all at once and make the data content corresponding to the latest brand. Is.

Specifically, as shown in FIG. 2, when the main control unit 2'receives the terminal start-up information, it updates the device date (S1), and the normal stock information update table 21b.
Is cleared (S2), and the contents of the data editing table 21a stored in the FD3 are expanded on the memory 21 (S3). 2. FIG. 2 is a flow chart of the terminal startup information editing process of this device.

Further, when the main controller 2'receives the brand information, as shown in the flowchart of the brand information editing process of the present apparatus in FIG. 3, the content of editing the data corresponding to the brand number of the received brand ( (Data restraint information, indicative restraint information, etc.) are set in the normal stock information update table 21b and the data edit table 21a (S11).

When the brand information is received for the first time, the main controller 2'needs to edit the previous day's closing price information, so that the contents of the normal brand information updating table 21b are stored in the data editing table 21a. It is designed not to overwrite. Further, when the brand information is received for the second time or later and is normal reception, after performing step S11, the normal brand information update table 21b is transferred to the normal brand information update table 21a from the normal brand information update table 21b. In order to prevent the latest data edit contents from being lost in the event of a system failure, etc., the data edit table 21b in FD3 is overwritten by overwriting the contents of 21b (data look-ahead information etc.) (S13). The edited content of the normal stock information update table 21b is also stored in the storage position (S14). Process S
If the reception is not normal at 12, the overwrite process is not performed, but if the reception is abnormal at all three times, the current contents of the data editing table 21a are stored in the FD 3 as they are (S15). . Here, the reason why the tables are overwritten not after the first time but after the second time is that the last day's closing price information is received after the first day's stock information is received. This is because the brand information update process is performed.

Further, when the main control unit 2'receives the previous day's closing price information or the front / rear trading information, as shown in FIG. 4, the editing corresponding to the stock number of the front / rear trading information is performed from the data editing table 21a. The information is taken out, and editing processing such as data suppression and quote suppression is performed (S21). 4. FIG. 4 is a flowchart of the previous day's closing price information and the previous / post-place information processing of this device.

When the editing process at the time of receiving each of the above-mentioned information is completed, the main control section 2'determines whether or not the stock data itself is suppressed or a part of the data such as the indicative information is suppressed based on the edited contents. , The data editing table 21a and the normal stock information updating table 21b are edited,
The edited data is passed to the transmission buffer 12. FD3
The contents of the data editing table 21a having the edited securities information are the contents of the normal stock information updating table 21b in the case of the process S14 of FIG.

Next, the operation of the data transfer apparatus of the present invention will be specifically described. Upon receiving the terminal start-up information in the reception buffer 11, the main control unit 2 ′ updates the device date and updates the normal brand information table 21 b in the memory 21.
Is cleared and the contents of the data editing table 21a stored in the FD 3 are expanded on the memory 21.

When the first brand information is received,
The main control unit 2'updates the contents of the normal brand information updating table 21b, and updates the contents of the data editing table 21a corresponding to the brand number of the received brand (data restraint information, indicative restraint information, etc.).

Next, when the previous day's closing price information is received, the main control section 2'takes out the editing information from the position of the corresponding stock number on the data editing table 21a, and according to it,
The edited data is output to the transmission buffer 12 by performing editing processing such as data suppression and sign suppression.

Next, when the second brand information is received, the main control unit 2'updates the contents of the normal brand information updating table 21b, and the data editing table 21a corresponding to the brand number of the received brand is updated. Update the contents (data suppression information, quote suppression information, etc.). When the second receipt of the brand information is normal, the normal brand information updating table 21b is overwritten (copied) with the contents of the normal brand information updating table 21b to the data editing table 21a. Data editing table 21a in FD3

Next, when the foreground information is received, the main control unit 2'takes out from the data editing table 21a the editing information corresponding to the brand number of the fore / aft information, and performs the editing processing such as data suppression and quote suppression. Then, the edited data is output to the transmission buffer 12.

Next, when the third brand information is received, the main control unit 2'updates the contents of the normal brand information updating table 21b, and the data editing table 21a corresponding to the brand number of the received brand is updated. Update the contents (data suppression information, quote suppression information, etc.). If the third receipt of the brand information is normal, the normal brand information updating table 21b is overwritten with the contents of the normal brand information updating table 21b to the data editing table 21a.
The edited contents of the normal stock information update table 21b are saved in the save position corresponding to the data edit table 21a in D3. Also in this case, if the reception is not normal, copying between tables is not performed and the conventional brand number remains in the data editing table 21a. If the third reception of the brand information is not normal, the contents of the conventional data edit table 21a are stored in the FD3.

Next, when the after-sales information is received, the main control unit 2'takes out the editing information corresponding to the brand number of the before-and-after-sales information from the data editing table 21a, and performs the editing processing such as data suppression and quote suppression. Then, the edited data is output to the transmission buffer 12.

According to the data transfer apparatus and the brand information processing method therefor of the present invention, the contents of the normal brand information updating table 21b are cleared when the terminal startup information is received,
Further, when the brand information is received, the contents of the data editing table 21a and the normal brand information updating table 21b are updated, and further 2
At the time of receiving the brand information after the first time, if it is a normal reception, the contents of the normal brand information updating table 21b are copied to the data editing table 21a and the brand is updated at any time, so that it remains in the data editing table 21a. Unnecessary data can be deleted without fail for 10 days without fail when receiving stock information for the second time or later. Therefore, when the previous day's closing price information is received, it is possible to check the unupdated date of the stock information update date and edit the closing price information on the previous day. What has been done is that this device does not require an unupdated check, so there is an effect that the closing price information on the previous day can be edited and transferred to the data display terminal without delay.
