However, there is a problem that a dedicated line or the like is required between the stock price information distribution server and the stock price information display terminal, resulting in an expensive system.

  Specifically, the transaction information distributed from the stock price information distribution apparatus of the stock exchange is roughly classified into order information (multiple quotation information), execution information, statistical information, and the like. Multi-quote information is necessary to see trends in stock prices and order quantities when buying and selling stocks, but there are cases where updates of 10 times / second or more may occur for the stocks that are of interest. The amount was large.

  In addition, as a usage, all the update information that occurs in a large amount in a short time for a stock price information display terminal of the stock price information display system (for example, multiple quotation information is updated 10 times / second or more). ) Cannot be confirmed with the eye, unnecessary information is included in the update information. In addition, the load on the network increases, making it difficult to see frequent updates on stock price information display terminals, resulting in reduced display efficiency. There was a problem of doing.

  The present invention has been made in view of the above circumstances, and the stock price information is thinned out according to the type of stock price information data to reduce the load on the system, improve the display efficiency, and prevent the system from becoming expensive. An object is to provide a stock price information display system.

  The present invention for solving the problems of the above conventional example is a stock price information display system including a stock price information receiving server that receives stock price information distributed from an information vendor, processes the data, and distributes the data to a stock price information display terminal. The stock price information receiving server includes a reception process, a data storage process, a thinning control process, and a transmission process as processes for the processing unit to read and implement the processing program, and the storage unit stores the received stock price information. Receive data queue for storing data, decimation setting parameter table for setting whether to decimate each received data type, and received data storage for storing received data by item indicating data type for each brand Table, transmission data queue for storing transmission data, update of received data by item indicating data type for each brand An update flag table for setting information indicating whether or not there is a decimation timer table for setting a timer value for each brand, and the reception process receives the stock price information distributed from the information vendor, and receives the data queue The data accumulation process notifies the reception event to the data accumulation process. When the data accumulation process receives the notification of the reception event, the data accumulation process acquires the reception data from the reception data queue and indicates the data type for each brand in the reception data accumulation table. Received data is stored as update data for each item, and it is determined whether or not the type of received data is a thinning target by referring to the thinning setting parameter table. If it is read and set in the transmission data queue, and it is a thinning target, the corresponding in the update flag table Set information indicating that the item has been updated, and set it to “1” if the timer value of the corresponding symbol in the decimation timer table is “0”, and the decimation control process will periodically decimate When the timer value in the timer table is incremented and the timer value exceeds a specific value, the update flag table is referenced and the received data of the item for which the corresponding brand has been updated is set in the transmission data queue and the decimation timer The timer value of the corresponding brand in the table is reset to “0”, and the transmission process sequentially transmits the transmission data stored in the transmission data queue.

  According to the present invention, a reception process receives stock price information distributed from an information vendor, stores it in a reception data queue, notifies a reception event to the data storage process, and the data storage process receives a notification of the reception event. The received data is acquired from the received data queue, the received data is stored as update data for each item indicating the data type in the received data accumulation table, and the type of received data is determined by referring to the thinning setting parameter table. If it is not a thinning target, the corresponding received data is read from the received data accumulation table and set in the transmission data queue, and if it is a thinning target, it is added to the item of the corresponding brand in the update flag table. Set the information indicating that there was an update, and the timer value of the corresponding brand in the thinning timer table If it is “0”, it is set to “1”, and the thinning-out control process periodically increments the timer value of the thinning-out timer table, and when the timer value exceeds a specific value, the update flag table is referred to and the corresponding action is taken.

[Outline of the embodiment]
In the stock price information display system according to the embodiment of the present invention, in the stock price information receiving server, the receiving process receives the stock price information distributed from the information vendor, stores it in the receiving data queue, and sends a receiving event to the data accumulation process. When the data storage process receives the notification of the reception event, the reception data is acquired from the reception data queue, and the reception data is stored as update data for each item indicating the type of data in the reception data storage table. Referring to the thinning setting parameter table, it is determined whether the type of received data is a thinning target. If it is not a thinning target, the corresponding received data is read from the reception data accumulation table and set in the transmission data queue. If this is the case, it indicates that the corresponding stock item in the update flag table has been updated. If the timer value of the corresponding brand in the decimation timer table is “0”, it is set to “1”, and the decimation control process periodically increments the timer value in the decimation timer table. When the specified value is exceeded, the update flag table is referred to, the received data of the item for which the corresponding brand has been updated is set in the transmission data queue, and the timer value of the corresponding brand in the decimation timer table is set to “0”. Since the transmission process sequentially transmits the transmission data stored in the transmission data queue, stock price information can be thinned out at specific value intervals according to the type of data, reducing the load on the system In addition, the display efficiency can be improved and the system can be prevented from becoming expensive.

  In the stock price information display system according to the embodiment of the present invention, in the stock price information receiving server, the number of transmission waiting data in the transmission data queue is stored in the transmission waiting data number storage unit, and the number of data is preset. When the value exceeds the upper limit value, all items are subject to thinning regardless of the setting contents of the thinning setting parameter table, and when the number of data falls below the preset lower limit value, the setting contents of the thinning setting parameter table Regardless of the number of data to be thinned out, no thinning-out, selective thinning-out processing, and forced thinning-out processing are executed depending on the number of data waiting to be transmitted. There is.

  The outline of the stock price information display system according to the embodiment of the present invention is basically the same as the system shown in FIG. 4, but the processing process in the stock price information receiving server 2 and the contents of the table and the like associated with the processing are conventional. Different from the ones.

Then, the processing program stored in the storage unit is operated by the control unit to realize a processing process described later.

[Stock price information receiving server: Fig. 1]
A stock price information receiving server in a stock price information display system according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a diagram showing a detailed processing operation of the stock price information receiving server according to the embodiment of the present invention. In FIG. 1, straight arrows indicate the flow of data, broken arrows indicate the flow of events, and (numerals) indicate processing procedures.

  As shown in FIG. 1, the stock price information receiving server (present receiving server) according to the embodiment of the present invention includes, as processing processes, a reception process 21, a data storage process 22, a transmission process 23, and a thinning process 31. As a data storage area necessary for executing these processes, a reception data queue 24, a reception data accumulation table 25, a transmission data queue 26, a transmission waiting data number storage unit 32, and a thinning setting parameter table 33 are provided. The update flag table 34 and the thinning timer table 35 are provided.

  Before explaining the detailed processing operation in the reception server 2, the reception data queue 24, the reception data accumulation table 25, the transmission data queue 26, the transmission waiting data number storage unit 32, the thinning setting parameter table 33, the update The contents of the flag table 34 and the thinning timer table 35 will be described.

[Reception data queue 24]
The reception data queue 24 stores reception data from the reception process 21 and is read by the data accumulation process 22 by a reception notification event.

[Reception data accumulation table 25]
The received data accumulation table 25 includes four-value data (4P) contracted for each brand (brand ID, brand code, brand name, etc.) by the data accumulation process 22, the quotation data (Q1) closest to the contract, and contracts. The second closest quotation data (Q2),... Are stored for each item (data type).
The received data storage table 25 is rewritten by overwriting data contents when updated with received data.

[Transmission data queue 26]
In the transmission data queue 26, when the thinning process is not performed, the data accumulation process 22 sets transmission data based on the reception data accumulation table 25. When the thinning process is performed, the thinning control process Reference numeral 31 sets transmission data based on the reception data accumulation table 25, and the transmission program 23 transmits transmission data to the stock price information distribution server 3 from the head of the queue.

[Transmission Waiting Data Number Storage Unit 32]
The transmission waiting data number storage unit 32 stores the number of data waiting for transmission. When the data accumulation process 22 sets the transmission data in the transmission data queue 26, “+1” (addition) is performed, and the transmission process 23 performs transmission processing. When it is performed, “−1” (subtraction) is performed.

[Thinning setting parameter table 33]
In the thinning setting parameter table 33, “Yes” or “No” is set in advance for each tag (data type: item) attached to received data. The received data of the tag set to “Yes” is subject to thinning, and the received data of the tag set to “No” is not subject to thinning.

  However, depending on the numerical value of the number of data waiting to be transmitted, all the received data is transmitted without decimation or all the received data is deciphered without referring to the decimation setting parameter table 33. Details will be described later.

[Update flag table 34]
In the update flag table 34, when the data of 4P, Q1,... Is updated for each brand (brand ID, etc.), the data storage process 22 sets “Yes” for each item (data type) for the brand. If there is no update, “None” is set. If the thinning control process 31 sets update data in the transmission data queue 26, “Yes” is changed to “None” (cleared).

[Thinning timer table 35]
In the thinning timer table 35, a timer value is set for each brand (brand ID, etc.). The data accumulation process 22 is reset to “0” and set to “1”. Set (add) to “+1” and reset to “0”. Details will be described later.

Next, the reception process 21, the data accumulation process 22, the transmission process 23, and the thinning control process 31 in FIG. 1 will be specifically described.
[Reception process 21]
The reception process 21 receives data from the stock price information distribution apparatus 1 (1) and stores it in the reception data queue 24 (2). Then, the reception process 21 notifies the data storage process 22 of a reception event notifying that data has been received (3).

[Data accumulation process 22: FIG. 2]
Next, specific processing of the data storage process 22 will be described with reference to FIGS. FIG. 2 is a processing flowchart in the data accumulation process 22. In FIG. 2, (S number) indicates the order of the processing steps.
As shown in FIGS. 1 and 2, the data storage process 22 determines whether or not there is a reception event notification from the reception process 21 (S1), and if there is a notification (in the case of Yes), the reception data queue 24 Received data is acquired from (4) (S2). If there is no notification (in the case of No), the determination process S1 is repeated.

  The data accumulation process 22 accumulates the data acquired from the reception data queue 24 in the reception data accumulation table 25 on a brand-by-item basis (5) (S2). For example, when the received data is the 1st to 16th closest quotation data (Q1 to Q16 data) for the brand B, the received data is set (updated) in the columns Q1 to Q16 of the brand B in the received data accumulation table 25. Is done.

  Further, the data accumulation process 22 refers to the number of transmission waiting data in the transmission waiting data number storage unit 32, selects “no thinning” if it is smaller than the first reference value (reference value A), and sets the second reference When the value (reference value B) is greater than “forced thinning process” and the number of transmission wait data is greater than or equal to reference value A and less than or equal to reference value B (reference value A ≦ number of transmission wait data ≦ reference value B), A selective thinning process is selected (6-1) (S3).

  In the case of “selective thinning process”, the data storage process 22 refers to the thinning setting parameter table 33 (6-2) and determines whether or not the tag attached to the received data is a thinning target (S4). . If the received data is not a thinning target (No), the process proceeds to step S5. If the received data is a thinning target (Yes), the process proceeds to process S8.

The data accumulation process 22 edits the received data into transmission data in the case of “no decimation” and when it is not a decimation target (in the case of No), and stores it in the transmission data queue 26 (7) (S5). The number of data waiting for transmission is set to “+1”, and update “none” is set in the update flag table 34 for the corresponding brand item (8-1) (S6).
Next, the data accumulation process 22 resets the timer value to “0” for the corresponding brand in the thinning timer table 35 (8-2) (S7), and ends the process.

  Further, in the case of “forced thinning process” and when the data accumulation process 22 is a thinning target (in the case of Yes), the update “present” is set for the item of the corresponding brand in the update flag table 34 (8 -1) (S8), it is determined whether the timer value of the corresponding brand in the thinning-out timer table 35 is “0” (timer value = 0?) (S9). In the case of “0” (in the case of Yes), the timer value of the corresponding brand is set to “1” (8-2) (S10), and the process is ended.

[Thinning control process 31: FIG. 3]
Next, specific processing of the thinning control process 31 will be described with reference to FIGS. FIG. 3 is a process flowchart in the thinning control process 31. In FIG. 3, (S number) indicates the order of the processing steps.
As shown in FIGS. 1 and 3, the thinning control process 31 is periodically started, refers to the thinning timer table 35 (S11), and sets a timer value other than “0” to “+1” (addition). (S12).

  Then, the thinning control process 31 determines whether or not the timer value in the thinning timer table 35 exceeds a specific value (9-1) (S13). Here, the specific value defines the interval of the thinning process. When the value is large, the thinning interval is long, and when the value is small, the thinning interval is short.

If the specific value is not exceeded in the determination process S13 (in the case of No), the process is terminated.
If the specific value is exceeded in the determination process S13 (in the case of Yes), the thinning-out control process 31 refers to the update flag table 34 for the stock whose timer value has exceeded the specific value, and there is an update. The transmission data is edited for all the update data items and stored in the transmission data queue 26 (9-2) (S14).

Then, the thinning-out control process 31 sets update “none” for the item of the brand whose transmission data has been edited in the update flag table 34 (S15).
Further, the thinning control process 31 performs processing for resetting the timer value of the corresponding brand in the thinning timer table 35 to “0” (9-1) (S16), and ends the processing.

[Transmission process 23]
The transmission process 23 transmits the transmission data from the head of the transmission data queue 26 to the stock price information distribution server 3 (10).
Then, when transmitting the transmission data, the transmission process 23 performs a process of “-1” (subtracting) the transmission waiting data number in the transmission waiting data number storage unit 32.

[Effect of the embodiment]
According to this receiving server, whether or not to be subject to thinning processing is set in the thinning setting parameter table 33 in accordance with the tag attached to each received stock information data item, and is subject to thinning. When receiving the data of the brand related to the tag, the data accumulation process 22 sets update “Yes” in the corresponding item of the brand in the update flag table 34 and sets “1” in the thinning timer table 35, and performs the thinning control process. When 31 periodically increments the value of the thinning timer table 35 and exceeds a specific value, the reception data stored in the reception data accumulation table 25 is set in the transmission data queue 26 and the transmission process 23 performs transmission processing. Since the items to be thinned in the thinning setting parameter table 33 are thinned at specific value intervals. You can, can reduce the load on the system, thereby improving the display efficiency of the stock information display terminal.

  Further, according to the present reception server, the number of data waiting for transmission in the transmission data queue 26 is stored in the number of data waiting for transmission storage 32, and when the number of data exceeds a preset upper limit value, thinning setting is performed. Regardless of the setting contents of the parameter table 33, all are subject to thinning, and when the number of data falls below a preset lower limit value, all are not subject to thinning regardless of the setting contents of the thinning setting parameter table 33. Thus, no thinning, selective thinning processing, and forced thinning processing are executed depending on the number of data waiting to be transmitted, and there is an effect that efficient processing at the receiving server can be realized.

[Another embodiment]
Next, a stock price information receiving server (another receiving server) according to another embodiment will be described.
Another receiving server holds the thinning setting parameter table 33 for each time period, and the data accumulation process 22 selects the corresponding thinning setting parameter table 33 from the data reception time, and the selected thinning setting parameter is selected. The thinning process is executed in accordance with the contents of the table 33.

  In addition, another receiving server sets “Yes” or “No” for thinning for each time period in the thinning setting parameter table 33, and the data storage process 22 sets “Yes” for thinning according to the data reception time. “None” is read, and the thinning process is executed for the thinning target.

  According to another receiving server, it is possible to change the thinning method in the time zone. For example, when dealings are close (9: 00: 9-9: 15), only the quotation information is thinned out, and the contract information is not thinned out. Although it is set, when the place is settled (after 9:15), it is possible to set so that all information is not thinned, and there is an effect that thinning processing according to the actual situation of the transaction can be realized.

  The present invention is suitable for a stock price information display system in which stock price information is thinned out according to the type of data of stock price information to reduce the load on the system, improve display efficiency, and the system does not increase in cost.
