2. Description of the Related Art A conventional information display system will be described with reference to FIG. FIG. 8 is a schematic configuration diagram of an information transmission system including a conventional information display system. As shown in FIG. 8, a conventional information transmission system is provided at a stock exchange or the like, and has a center 1 for distributing securities information, and an opening price, a high price, and a price for each brand distributed from the center 1 via a communication line. Low price,
A server 2 'for receiving and storing securities information including a current value, a sign, etc., and a plurality of clients 3'-1 (clients 1 to 3') for acquiring and displaying the latest securities information on an arbitrary brand from the server 2 '. -n (client n). Here, a part composed of the server 2 'and the client 3' is referred to as an information display system.

[0003] The server 2 'is provided with an automatic update registration table (not shown) for automatically registering brands to be distributed to the client 3' when data is updated. The automatic update registration table will be described later with reference to FIG.

An automatic updating method in the above conventional information display system will be described with reference to FIG. FIG. 9 is an explanatory diagram showing an automatic updating method in a conventional information display system. As shown in FIG. 9, in the conventional information display system, when the security information screen is displayed on the client 3 '(security screen display (1)), the client 3' automatically updates and registers the displayed brand in the server 2 with respect to the displayed brand. A request is issued (2). Thus, the server 2 'registers the brand for which the client 3' has requested automatic update registration in the automatic update registration table 21 in the server 2 '(automatic update registration (3)).

[0005] Thereafter, when the security data (security information) is received from the center 1 (4), the server 2 'determines whether or not the issue is an automatically updated and registered issue (automatic update registration check (5)). If so, an automatic update notification is sent to the client 3 'that has automatically registered the brand (6).

The client 3 'makes an update data acquisition request to the server 2' with the automatic update notification (6) as a trigger (update data acquisition request (7)). The server 2 'transmits the latest data of the brand requested by the client 3' to the client 3 ', triggered by the update data acquisition request (7) (8).

Here, an automatic update registration request from the client 3 'to the server 2' in the conventional information display system will be described with reference to FIG. FIG. 10 is a diagram showing a conventional automatic update registration request on the client side. As shown in FIG. 10, in the conventional client 3 ′, when the security screen is displayed, the displayed brands are read as automatic update registration brands for each client 3 ′, and an automatic update registration request is issued to the server 2 ′ (FIG. 9). (2)) is transmitted.

[0008] In the securities information, the open price, high price,
It contains information on a plurality of various items such as a low price, a current value, a comparison, a trading volume, a quotation, and the like. When displaying the security information on the client 3 ', the security information for each brand received from the server 2' is included. , Data of items set by each user for each brand is extracted and displayed. Therefore, even if the clients 3 'display the same brand, items required for display may differ for each client 3'.

In the example of FIG. 10, in the client 3'-1, "brand 1" is set so as to display data of six items of opening price, high price, low price, present value, comparison and trading volume. , "Brand 2" are set to display three items of data: current value, comparison, and volume.

Next, an automatic update registration table 21 in the server 2 'of the conventional information display system is shown in FIG.
This will be described with reference to FIG. FIG. 11 is a diagram showing an automatic update registration table 21 in a conventional server 2 '. As shown in FIG. 11, the automatic update registration table 21 in the conventional server 2 'stores all brands automatically updated and registered from the client 3' as automatically registered brands (automatically updated brands 1 to 5). n), and further stores a flag (1/0) indicating from which client 3 'the brand is automatically updated and registered.

If the latest security information transmitted from the center 1 includes the automatically updated issue registered in the automatic update registration table 21, the server 2 'automatically updates and registers the issue. The automatic update notification is sent to the client that is running.

Next, the automatic update notification from the server 2 'to the client 3' in the conventional information display system shown in FIG. 9 (6) will be described with reference to FIG. FIG.
It is an explanatory view showing a data format of an automatic update notice from a server 2 'to a client 3' in a conventional information display system. As shown in FIG. 12, the automatic update notification from the server 2 'to the client 3' includes a header section, the number of updated brands, and a brand code of the updated brand (updated brand code).
Are transmitted from the server 2 'to each client 3' to notify the brand code of the updated brand among the brands registered automatically by the client 3 '. It is.

Next, an update data acquisition request from the client 3 'to the server 2' in the conventional display system shown in FIG. 9 (7) will be described with reference to FIG. FIG.
Is an explanatory diagram showing a data format of an update data acquisition request from a client 3 'to a server 2' in a conventional information display system. As shown in FIG. 13, the update data acquisition request includes a header portion, the number of acquired brands, and the acquired brand codes 1, 2,..., And the client 3 'requests the server 2' for the latest data. This specifies the brand to be executed. Here, the brand requested by the client 3 'is the brand currently displayed.

In the conventional information display system, in response to an update data acquisition request from the client 3 ', the server 2' updates the latest security information of the requested brand in units of brand, that is, data of all items of the brand. Is transmitted to the requesting client 3 '.

In the client 3 ', only data necessary for display is extracted from the security information of each brand transmitted from the server 2' and displayed.

As a conventional technique of an information distribution system for judging whether or not the data is update data by using a flag, the following is known:
JP-A-2000-242697 "Information distribution system" (applicant: Kokusai Electric Co., Ltd., inventor: Hideaki Takazawa et al.) Published on May 8, 2008 This prior art detects the presence or absence of an update due to price movement based on market information received by a received data processing means of a server, updates stock price information in a brand information storage table, sets an update flag, and sets a request reception processing means. Receives the distribution request from the client and distributes the brand attribute information, the stock price information, and the update flag for the distribution request brand, and thereafter, the distribution control processing means periodically updates the brand requested by the client. Judge,
An information distribution system that distributes stock price information and an update flag to a client only for stocks for which an update has been detected, thereby maintaining the real-time nature of the information distributed to the client to a certain extent while maintaining the latest update information in the client. Can be identified.

[0017]

However, in the conventional automatic updating method in the information display system, even if the data of the item not displayed by the client is updated, the client can display the brand if the brand is displayed. The update data acquisition request is transmitted based on the automatic update notification from the server, and useless transmission / reception for acquiring update data irrelevant to display occurs, and the communication volume between the server and the client increases. There was a problem.

Further, there is a problem in that unnecessary data is transmitted and received, so that a communication line and a memory are wasted.

The present invention has been made in view of the above circumstances, and provides a distribution control method capable of reducing the amount of communication between a server and a client associated with an automatic update display and operating the system efficiently. With the goal.

[0020]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art, the present invention provides a server for receiving and storing security information transmitted from a center, and obtaining and displaying security information from the server. A distribution control method in an information display system including a client, wherein the client comprises:
A display item corresponding to each automatically updated issue registered in the server is stored in advance, and when the security information of the automatically updated issue set in advance for each client is updated, the server updates the automatically updated issue. An automatic update notification including the updated brand and the updated item is transmitted to the registered client, and the client transmits, for each brand included in the received automatic update notification, the item included in the automatic update notification and the relevant brand. Compare the corresponding display item and
When at least one of the display items matches an item included in the automatic update notification, a request to acquire updated security information of the security is transmitted to the server, and no display item matches any item included in the update notification. Is characterized by not sending an acquisition request to the server /
The traffic between the clients can be reduced, and the system can be operated efficiently.

[0021]

Embodiments of the present invention will be described with reference to the drawings. A distribution control method according to an embodiment of the present invention is an information display system including a server and a client, in which the client sets display items for each brand to be automatically updated and displayed, and the server updates security information. When the issued brand is registered for automatic update, the client transmits an automatic update notification including the brand and data indicating the updated item to the client, and the client receives the received automatic update notification and the preset automatic update notification. Compared with the display items for each brand, a request is made to obtain update data for the brand whose display item data has been updated. This eliminates unnecessary data distribution and reduces the traffic between the server and client. Can be reduced.

Further, according to the distribution control method according to the embodiment of the present invention, when displaying an item requiring calculation on the client, the client performs the calculation only when the data of the item required for calculation is updated, If the data has not been updated, the data that has been displayed so far is used as it is, so there is no need to perform calculations every time the updated data is acquired, and the amount of processing at the client can be reduced. is there.

An information display system for realizing the distribution control method according to the embodiment of the present invention comprises a server and a client, like the information display system shown in FIG. 8, and is not shown here. . However, the processing in the server and the client is partially different from the conventional processing.

A distribution control method according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is an explanatory diagram showing a distribution control method (this method) according to an embodiment of the present invention. As shown in FIG. 1, in the present method, when the security information screen is displayed on the client 3, the client 3 sets the automatic update control information as in the conventional automatic update method (1).

At this time, as a feature of this method, the client 3 sets display items corresponding to each display brand together with the display brand in the automatic update control information. The setting of the automatic update control information will be described later with reference to FIG.

Then, the client 3 issues an automatic update registration request for the displayed brand to the server 2 based on the automatic update control information (2). In the server 2, the brand for which the automatic update registration request has been issued from the client 3 is registered in the automatic update registration table 21 in the server 2 (automatic update registration (3)).

After that, when security data (security information) is received from the center 1 (4), the server 2 sets the automatic update registration table 21 in the same manner as the conventional automatic update method shown in FIG.
It is determined whether or not the brand is automatically updated and registered (automatic update registration check (5). If the brand is a relevant brand, an automatic update notification is sent to the client 3 (6).

At this time, a feature of the present method is that the server 2
In the automatic update notification, not only the brand code of the brand to be updated, but also the updated item name in the security information of the brand is notified. The automatic update notification transmitted from the server 2 will be described later with reference to FIG.

When the client 3 receives the automatic update notification, the client 3 first refers to the automatic update control information to extract information on the brand currently displayed, and further updates items included in the automatic update notification for each brand. The display item set in the automatic update control information in (1) is compared (automatic update item check (7)).

As a result, if the update item matches the display item, that is, if there is a brand whose display item has been updated, a request is made to the server 2 to obtain update data of the brand (update). Data acquisition request (8)).

That is, in this method, the client 3
However, even if there is an automatic update notification of the automatically updated brand that is being automatically updated, acquisition of update data is not requested if the data of the display item of the brand has not been updated.

Then, the server 2 sends the latest data of the brand requested by the client 3 to the client 3 with the update data acquisition request (8) as a trigger (9). The method is performed in this manner.

As described above, at the stages (8) and (9), transmission and reception relating to data acquisition irrelevant to display are eliminated, so that it is possible to reduce the amount of communication as compared with the conventional case, and to make communication paths, memories, Can be effectively used.

Next, the automatic update control information set at the time of displaying the securities screen in the client 3 shown in (1) of FIG. 1 will be described with reference to FIG. FIG. 2 is an explanatory diagram showing the automatic update control information in the client 3.
As shown in FIG. 2, when the display state of the securities information screen is reached, the client 3 sets automatic update control information (automatic update brands and corresponding display items) based on the currently displayed brands and display items.

That is, when the display item is set, the client 3 (the control unit thereof) reads the display brand and the display item when the securities information screen is displayed, and sets it as automatic update control information. At this time, the display brand is set as the automatically updated brand, and the corresponding display items are set.

In the example of FIG. 2, in the client, “brand 1”, “brand 2”... Are set by the user as display brands, and “brand 1” is the open price, high price, low price, current value, , And six items of volume, and “brand 2” displays three items of current value, comparison, and volume.

In this case, the automatic update control information of the client is, for example, “brand 1” as “automatic update brand 1”.
Are set, and six items of “open price, high price, low price, current value, comparison, and volume” are set as the corresponding “display items”. In addition, “brand 2” is set as “automatically updated brand 2”, and “current value, comparison, volume” is set and stored as the corresponding “display item”.

The client 3 sends an automatic update registration request to the server 2 based on the automatic update control information (FIG. 1 (2)).

Here, the data of the display items in the client 3 shown in FIG. 2 will be specifically described with reference to FIG. FIG. 3 is an explanatory diagram showing a data format of a display item in the client 3. The display items are a part of the automatic update control information shown in FIG. 2 and are set corresponding to the automatic update brands, and are information indicating items to be displayed in the security information of each automatic update brand.

As shown in FIG. 3, the display items include bits corresponding to all items that can be displayed on the client 3, and among the bits, the bits are displayed on the client 3 in the information on the brand. "○" corresponding to the item
The “bit” is set to “1”, and “0” is set for items not to be displayed.

More specifically, in the case of "brand 1" shown in FIG. 2, the display bit is "1" because the six items of the opening price, the high price, the low price, the current value, the comparison display and the trading volume are items to be displayed. Is set to "0" because the selling price is not displayed.

Similarly, in the case of "brand 2" shown in FIG.
The display bits corresponding to the three items of “current value, comparison, and volume” are set to “1”, and the display bits of the other items are set to “0”.

Next, the automatic update notification from the server 2 to the client 3, which is a feature of the present method, will be described with reference to FIG. FIG. 4 is an explanatory diagram showing a data format of the automatic update notification from the server 2 to the client 3.

The automatic update notification from the server 2 to the client 3 shown in FIG. 1 (6) is transmitted from the server 2 to each client 3 in the same manner as in the prior art. Among the issues, the issue code of the updated issue is notified. As a feature of this method, an updated item in the security information of each issue is notified together with the issue code.

As shown in FIG. 3, the automatic update notification includes a header portion, the number of updated brands, a brand code of the updated brand (updated brand code), and an update item corresponding thereto. I have.

Here, the update items will be specifically described. The updated item is composed of bits corresponding to all the items included in the security information of each issue, and among those items, the item for which new data is received, that is, the received bit of the updated item includes ""1" is set.
Therefore, the received bit of the updated item is “1”, and the received bit of the item that is not updated is “0”.

Here, the operation of the server 2 when receiving the securities information from the center 1 will be described. When the server 2 receives the securities information from the center 1, the server 2 updates the automatic update table 2
1 to determine whether the issue is an automatically updated issue (automatic update issue), and if the automatically updated issue has been updated, an automatic update notification to the client 3 that has automatically updated the issue. Create

At this time, the server 2 determines which item of the data of the automatically updated brand is being updated, and determines the item of the “updated item” corresponding to the brand code of the brand in the automatic update notification. , The bit corresponding to the item being updated is set to “1”. Then, after checking the update items for all the automatically updated brands, an automatic update notification is created by adding the number of updated brands and a header portion, and the automatic update notification is transmitted to each client 3. In this way, the processing of the server 2 when receiving the security information from the center 1 is performed.

Next, the operation of the client 3 when receiving the automatic update notification from the server 2 will be described with reference to FIGS. 5 and 6 are explanatory diagrams showing the operation of the client 3 when receiving the automatic update notification from the server 2. When the client 3 receives the automatic update notification from the server 2, the client 3 compares the update item with the display item for the currently displayed brand among the brands included in the automatic update notification, and determines whether the display item has been updated. Request update data acquisition.

As shown in FIG. 5, the client 3 reads the update item corresponding to the brand currently displayed in the brand of the automatic update notification, and displays the display item in the automatic update control information set internally in advance. Compare.

More specifically, if there is an item in which both the received bit of the "update item" of the automatic update notification and the display bit of the "display item" of the automatic update control information are "1", the client No. 3 determines that the data of the item to be displayed has been updated, and issues an update data acquisition request for the brand.

In the example of FIG. 5, in the client, each item of "open price, high price, low price, current value (current value), comparison, volume, and ask price" is set as the display item. , The auto-update notification states "current value, volume,
"Sell" is set as an update item.

Thus, the client 3 determines that the three items of “current value”, “volume” and “sell price” are display items and have been updated, and changes the brand code of the relevant brand. It is set in the update data acquisition request.

When there is an item (operation item) which is calculated by performing an operation based on data of a plurality of items, such as “comparison”, the client 3 determines whether any of the data of the item to be substituted into the calculation formula Is updated, the brand is set in the update data acquisition request.

For example, “comparison” shown in FIG. 5 is calculated according to a calculation formula such as “comparison = current value−closing price on the previous day”.
That is, if “comparison” is a display item, the client 3 updates the “current value” and “last day's close price” as update items.
When any of the above is updated, an update data acquisition request is made.

As shown in FIG. 6, even if the received bit of "volume" is set to "1" in the update item of the automatic update notification, the display bit of "volume" is set to "0" as a display item. If there is, the client 3 does not display the trading volume of the brand, so the updated trading volume data is unnecessary in the client 3, and the update data acquisition request is not issued.

As described above, according to the present method, even if the server 2 receives the automatic update notification and the displayed brand is updated, if the updated item is not displayed on the client 3, the update data is not updated. Is not required, the communication amount between the server 2 and the client 3 can be reduced.

Next, the processing in the client 3 when receiving the automatic update notification from the server 2 will be described with reference to FIG. FIG. 7 is a flowchart illustrating a process in the control unit of the client 3 when receiving the automatic update notification. As shown in FIG. 7, upon receiving the automatic update notification from the server 2 (100), the client 3 reads one brand code (102) and determines whether the brand is currently being displayed (104).

In the process 104, if the brand is being displayed, the client 3 determines whether the update item corresponding to the brand in the automatic update notification is a display item. That is, it is determined whether or not the display item of the brand in the client 3 has been updated (10).
6). If a plurality of display items are set, it is checked whether at least one item has been updated.

If the display item has been updated in the process 106, the client 3 sets the brand code in the update data acquisition request and increments the number of brands by one (120).

Then, the client 3 determines whether there is a next brand, and if so, returns to the process 102 to repeat the same process for all brand codes included in the automatic update notification.

If the display item has not been updated in the process 106, the client 3 determines whether the item required for calculation has been updated when displaying the calculation item, that is, "comparison" is the display item. In this case, it is determined whether the “current value” or the “last day's close price” has been updated (108).
Temporarily stores the brand code in the control unit as a brand requiring calculation (110), and proceeds to processing 120.

If the brand read from the automatic update notification in the process 104 is not the currently displayed brand, and if the items required for the calculation have not been updated in the process 108, the client 3 proceeds to the process 122. I do.

When all the brand codes included in the automatic update notification received in the process 122 have been checked, the client 3 adds a header to the brand code of the brand whose update data is requested and the number of the brands. Is transmitted to the server 2 in the same format as the conventional update data acquisition request shown in FIG. 13 (124). The processing at the time of receiving the automatic update notification in the client 3 is performed in this manner.

Thus, according to the present method, the client 3 transmits an update data acquisition request to the server 2 only for brands whose display items have been updated, so that only data reflected on the display can be requested. This eliminates useless transmission and reception, and can reduce the communication amount between the server 2 and the client 3.

Next, the operation of the client 3 when acquiring update data will be described. When the client 3 receives the latest data transmitted from the server 2 based on the update data acquisition request, the client 3 stores and displays the received data. At this time, it is determined whether or not the brand is stored as a brand requiring calculation in the process 110 of FIG. 7, and if it is a brand requiring calculation, calculation is performed based on the latest data received and displayed.

As described above, the brands requiring calculation are not the received data as they are, but the items requiring calculation (calculation items).
Is displayed, and the data of items necessary for the calculation are updated. Specifically, for example, "comparison"
Is set as a display item, and a brand in which either the “current value” or the “last day's close price” required for calculating the “comparison” is updated is a brand requiring calculation. Such brands requiring calculation are displayed after the calculation is performed.

If the data is not stored as a brand required for calculation, the calculation is not performed at the time of obtaining the update data, and the calculation item such as “comparison” displays the data before update as it is. Thus, conventionally, when the update data is received, the calculation is performed for all the brands. However, the calculation can be performed only when the calculation result is reflected in the display update, and the processing in the client 3 is reduced. , Can be updated quickly.

According to the distribution control method according to the embodiment of the present invention, the client 3 previously stores the display items corresponding to the respective automatically updated brands, and the server 2 updates the security data of the automatically updated brands. In this case, an automatic update notification including the brand code and the updated item (updated item) is transmitted to the client 3 that has automatically registered the brand, and the client 3 is included in the automatic update notification. The update item corresponding to the brand is compared with the display item stored in advance corresponding to the brand, and when they match, an update data acquisition request for the brand is transmitted to the server 2. Update data can be requested only for brands whose items required for display have been updated, eliminating unnecessary transmission / reception associated with unnecessary data requests and communication between the server 2 and the client 3. There is an effect that can be reduced.

According to the present method, the client 3
However, when an operation item such as “Comparison” is a display item and an item required for the operation has been updated by an automatic update notification from the server 2, the relevant brand is stored as an operation required brand. When the update data is received from the server 2, only the brand requiring calculation is calculated and displayed, and if not, the data before the update is displayed as it is for the calculation item. Only the brand whose display is updated can be calculated, and the brands that are not updated can be displayed without calculation. This has the effect of reducing the processing load on the client 3 and promptly updating the display.

[0071]

According to the present invention, when a client receives an automatic update notification from a server, the client updates an updated item and a previously stored display item for each brand included in the automatic update notification. In comparison, if at least one matches, a distribution control method that transmits an update information acquisition request to the server, and does not transmit an update information acquisition request if none match, is accompanied by automatic update display. There is an effect that the communication amount between the server and the client can be reduced and the system can be operated efficiently.
