JP3764907B2 - Information provision system via the Internet with a browser with access control function on the client side - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, a server computer that provides an access control function on the client terminal side is installed in advance, and a server computer that provides information via the Internet causes the server to be accessed by frequent access from the client terminal. The present invention relates to an information providing system that controls overloading.
[0002]
[Prior art]
Conventionally, information provision via the Internet is performed by a computer including a Web server that responds to an access signal from a client terminal in which a general Internet browser is installed.
[0003]
The general function of the Internet browser is to click on a hypertext markup language (HTML) hyperlink on a Web page to access the server, acquire information, and display it on the display unit of the client terminal. Also, JP 2000-311134 and JP 2002-215481 are known as prior art documents regarding access control, and JP 2001-177196 A and JP 2001-344196 A are related to dedicated browsers.
[0004]
However, there are the following problems. In other words, in addition to the information data itself requested by the user, HTML language tags, HTML auxiliary languages for setting designs such as Web page layout display, and the display on the Web page are made interactive with a window box or the like. Since it is necessary to include Web page editing information such as HTML auxiliary language to be included in the transmission data from the server via the Internet, the amount of communication data increases, and if the request frequency per unit time to the server is high, the response decreases and the network Band pressure was occurring.
[0005]
For example, in the odds value in the horse racing information or the winning horse information data for each race, the request frequency per unit time is very high. In addition, since there is no means for suppressing the frequency of access requests, there has been a problem that the number of access requests to the server increases more than the increase in the number of users / users.
[0006]
That is, if one user requests information data from the server at twice the normal frequency, the load is the same as when two users use the server. Furthermore, if a user develops a program having a communication function for repeated access and continues to send information requests to the server, a server load for several hundred users will occur for one user. . In order to cope with these, there was no method other than increasing the number of server computer facilities. From the above, it was a wasteful increase in equipment.
[0007]
Moreover, since the user wants to browse the data (odds information etc.) which changes every moment, there are many requests repeatedly. However, the server-side information data is updated at regular intervals, and the display content does not change even if requested multiple times during that time. For this reason, a load is applied to the server each time due to a user's “waste request”.
[0008]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described problems. By providing a dedicated browser having a function of controlling the request frequency to the server in the client terminal, the elapsed time-dependent information data is minimized from the second time. The browser is further provided with a display column form pattern including items necessary for displaying elapsed time-dependent information data in the browser, and data such as HTML tags is excluded from the information data from the server. The purpose is to provide an information providing system that allows users to transmit only necessary data from the server to the client terminal so that the amount of communication data can be narrowed down and can communicate over an ideal response and network bandwidth. .
[0009]

In addition to the browser function, when the data information selected on the front page from the information server computer is elapsed time-dependent data that changes with time, the client terminal is set at a predetermined unit time. Repetitive access control means for automatically making an access request to the information server computer at a repetitive frequency, and disregarding the reaccess selection signal input by the user or prohibiting reaccess from being transmitted.
Repetition frequency receiving means for receiving and storing the repetition frequency or a change coefficient for changing the repetition frequency from the information server computer,
The information server computer includes a repetition frequency correspondence table corresponding to the information service date and time, repeatedly measures the load state of the server with the passage of time, and calculates a change coefficient to obtain a repetition frequency corresponding to the load.

And a connection circuit unit 32 such as a modem connected to the Internet 20.
[0015]
Here, when the data information selected on the Web page from the information server computer 10 is elapsed time-dependent data that changes over time, the repeated access control means 31a is set for each predetermined unit time set in advance. It is a means for automatically making an access request to the information server computer at a repetition frequency and ignoring the re-access selection signal input by the user.
[0016]
More specifically, the repetitive access control means 31a reads a repetitive frequency (re-access time interval) set for each date and time with reference to a repetitive frequency table 31b-1 to be described later. 10 is read from the change coefficient table 31b-2, the reaccess time is calculated, and the information server computer 10 is automatically accessed.
[0017]
The repeated access control means 31a can be set so that the client side can make a selection for stopping automatic access (automatic access off / on selection). In the case of automatic access on, the user's re-access operation is prohibited, and even when automatic access is off, re-access within a time interval predetermined in the repetition frequency table 31b-1 can be ignored.
[0018]
The repetition frequency receiving means 31b is means for receiving and storing the repetition frequency or a change coefficient for changing the repetition frequency from the information server computer 10. When logging in to the information server computer 10, the repetition frequency is received and recorded in the repetition frequency table 31 b-1, and the subsequent change coefficient is received and recorded in the change coefficient table 31 b-2.
[0019]
Further, when acquiring a plurality of pieces of information data from the information server computer 10, the information data display means 31c provides a corresponding item display column for inputting the information data in advance, and inputs the acquired information data to the corresponding column. The means for displaying on the display unit of the client terminal 30.
[0020]
For example, information data such as odds in horse racing information is provided with an easy-to-read display field for displaying a limited combination of horse numbers and a combination matrix of frame numbers, and from the information server computer 10, only odds values of the contents of the matrix are provided. Is displayed in the corresponding column. The race table is a means for providing a display column of a display format such as a newspaper of horse racing information familiar to the user, and receiving and displaying only information data corresponding to the display column. Therefore, the client is easy to see and can reduce the communication data from the information server computer 10.
[0021]
The emergency notification data automatic display means 31d is a means for displaying the emergency communication information data from the information server computer 10 described later at a predetermined position on the display unit of the client terminal 30 when receiving emergency communication information data from the information server computer 10.
[0022]
For example, when emergency information such as canceling a race is received in the horse racing information, even if it is the current odds information display screen, a blinking (ticker) screen window is provided at the center of the screen to display the canceling information for a certain period of time. When the latest race confirmation information is received, an electric bulletin board style pop-up window can be provided at the bottom of the screen for display.
[0023]
On the other hand, the information server computer 10 includes at least a Web server 11 and a database device 12. The Web server 11 includes a repetition frequency change coefficient calculation unit 11a, a repetition frequency transmission unit 11b, an emergency notification data transmission unit 11c, Information data transmitting means 11d.
[0024]
The database device 12 includes at least a repetition frequency correspondence table 12a, a change coefficient table 12b, an emergency notification information data table 12c, and a provision information data table 12z.
[0025]
The repetition frequency change coefficient calculating means 11a sequentially measures the load state of the information server computer 10 over time, calculates a change coefficient for setting a repetition frequency corresponding to the load, and records it in the change coefficient table 12b. It is. For convenience of explanation, the change coefficient table 12b is a file, but it is information that changes from moment to moment, and the change coefficient value is provided in the memory at the time of implementation.
[0026]
In this means, the machine load is measured using a known load average monitoring function provided in the OS of the information server computer 10, and when the load is high with respect to the load target value, the change coefficient is set to 1.0 or more, The time interval of the repetition frequency is extended twice or three times, and if it is less than or equal to the load target value, the change coefficient is set to less than 1.0 and the time interval is shortened. The time interval of the repetition frequency is provided with the shortest repetition interval or the longest repetition interval in the time obtained by multiplying by the change coefficient to prevent meaningless short-term repetition.
[0027]
The repetition frequency transmitting means 11b is a means for transmitting the repetition frequency of the day and the change coefficient at that time when logging in or accessing from the client terminal.
[0028]
For example, in the horse racing information, at the time of login, it is determined whether the current day is a weekday or an event date from the repetition frequency correspondence table 12b, and the repetition frequency interval reference for that day is read and transmitted. Note that the repetition frequency interval reference can be stored in advance in the repetition frequency table 31b-1 of the browser with an access control function installed in the client terminal 30 in advance. In this case, this means is used to change only when the interval reference is changed.
[0029]
Further, the emergency notification data transmission means 11c is responsive to the access request contents whenever there is an access from the client terminal 30 when the emergency notification information data to be transmitted to the client terminal 30 is urgently generated. Instead, it is means for transmitting the emergency notification information data to the client terminal 30 each time.
[0030]
For example, in the horse racing information, when race cancellation or the like occurs, race confirmation information immediately before the day of the event is read from the emergency notification information table 12c and transmitted. The recording / updating of the emergency notification information table 12c is performed by the information management server, but the description is omitted.
[0031]
Further, the information data transmission unit 11d is a unit that searches the transmission information table 12z for information data of a Web page to be transmitted in response to a request from the client terminal 30, and transmits the information data.
[0032]
At this time, only the information data to be input to the corresponding item display field without including Web page editing information such as an HTML tag, a Web page design setting language, and a Web page interaction language to be added to the Web page information data in the communication data. Send.
