Description

Detailed Description of the Invention

[0001]

[Industrial field of use] The present invention relates to an inquiry response system composed of a host computer (hereinafter referred to as a host) -terminal control device-terminal device (hereinafter referred to as a terminal). Is a series of operations) that consists of multiple screens and is suitable for the case where it is necessary to change the page sequentially from the top screen to check the contents, and a multi-screen display that can display the page break results in a shorter time Regarding the scheme.

[0002]

2. Description of the Related Art For the purpose of displaying status judgment (reservation status, etc.), as described in the inquiry system of Japanese Patent Laid-Open No. 58-31624, a local database is provided in the terminal control unit to improve operability and There are also means for improving responsiveness.

In order to reflect the situation that changes moment by moment on a nationwide scale, the host-centralized type is more accurate than the decentralized database, and newer information can be equally provided to any operator. However, I was inquiring about the necessary information to the host each time,
If there are many screens, it will take time.

[0004]

In order to shorten the time required for page breaks, it is best to eliminate the inquiry response time to the host or shorten it as much as possible. In a system in which decentralization is not desirable, there is no choice but to reduce the latter inquiry response time. An object of the present invention is to display the first screen of the work requested by the operator and use the time for confirming the contents to automatically receive a certain number of pages from the next screen on the terminal control device. By providing the multi-screen display method, it is possible to reduce the time required for page breaks of multiple screens.

[0005]

In the present invention, page number and page number designation information is provided in the inquiry information from the terminal control device to the host, and the screen information for the designated number of pages after the designated page number is provided from the host. I sent it to the terminal controller. And
A buffer for accumulating a plurality of screen information is provided in the terminal control device, and screen information for a certain number of pages is collectively received from the host, and if there is a page break request from the terminal, the terminal control device The screen information stored in was sent to the terminal. At this time, only the top screen information is received first and displayed on the terminal, and the contents of the buffer are deleted when there is a display request for a new job.

[0006]

By incorporating the page designation in the inquiry information from the terminal control unit to the host and by providing the storage buffer in the terminal control unit, a single host inquiry can generate a certain number of pages in the terminal control unit. The screen information can be stored, and when the operator makes a page change request for the screen, the requested screen can be displayed without inquiring to the host. This allows
The page break operation response time is shortened.

Further, if the host is inquired about all the plural screens for a certain number of pages, the editing time of the host becomes long,
The response time to display the top screen becomes long. Therefore, only the top screen information is received first and displayed on the terminal,
By continuously inquiring about the subsequent screens to the host, the deterioration of the response time until the first screen is displayed is prevented.

By deleting the buffer at the time of requesting the display of the first screen in each work, old screen information is provided to the operator, that is, the freshness of the information is prevented from being deteriorated.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a system configuration diagram in an embodiment of the present invention. In this embodiment, one host 1 having a database 4 is connected to a plurality of terminal control devices 2 via a line, and each terminal control device 2 is connected to a plurality of terminals 3 via a line. Is becoming Further, although the relation of each function in the terminal control device 2 is shown, only representative functions are described for the description of the embodiments of the present invention. As an outline of the processing, first, the input control function 5 receives a display request and a page break request from an operator, refers to the page management table 9,
It is determined whether or not the relevant work has already been accumulated in the screen accumulation buffer 10. If not yet completed, host inquiry function 6
Request an inquiry to the host 1. If you have accumulated
The screen display on the terminal 3 is requested to the output control function 8. The host inquiry function 6 refers to the page management table 9 and determines whether the inquiry is for the top screen. If it is the first screen, the inquiry information 11 of only a single screen, and if it is not the first screen is created, it is sent to the host 1. The host 1 reads necessary data from the database 4 according to the inquiry information 11, edits the designated screen information for the designated number of pages, and transmits it as response information 12 to the terminal control device 2. When the response information 12 from the host 1 arrives, the response reception function 7 updates the page management table 9 and stores the screen information in the screen storage buffer 10. If the response is a single screen, the output control function 8 is sent to the terminal 3. After making a screen display request to the host, the host inquiry function 6 is requested to make a host inquiry for the remaining screens. Finally, the output control function 8 refers to the page management table 9, fetches the screen information requested to be displayed from the accumulation buffer 10, converts it into a terminal output code, and outputs it to the terminal 3.

Next, FIG. 2 shows a configuration diagram of the related table.
The screen storage buffer 10 is a table that stores screen information received from the host 1, and stores one page of screen information in one record. In this embodiment, screen information for 10 pages can be stored in the terminal control device 2. The page management table 9 includes a job name 13 that stores the name of a job requested to be displayed or page-changed by the operator of the terminal 3, each record in the screen storage buffer 10, and the screens stored in each record. Record No. page N that correlates page No.
o. Correspondence information 17 and record No. page No. Corresponding to the number of the case where the first page of the No. correspondence information 17 is stored Shows the first page case No. 14 and the number of the case where the last page is stored The final page case No. 15 and the displayed page case No. 16 indicating the number of the case in which the page No. of the screen being displayed on the terminal 3 are stored.

FIG. 3 shows inquiry information 11 and response information 12.
Shows the data stream of. The inquiry information 11 is
A job name 13 that specifies the job name for the host 1,
Request top page N indicating how many pages are requested from which page
o.18 and 19 required pages. Also, the response information 12
Is the business name 13 inquired from the terminal control device 2,
Requested first page No. 18, requested page number 19, total page number 20 indicating how many pages of the corresponding job screen are in total, response page number 21 indicating how many pages have been transmitted, and The screen information 22 includes 21 response pages. While the terminal control device 2 requests a plurality of screens for m pages (one page, nine pages, or four pages), the host 1 has more than m pages of remaining screen information. When m is less than m pages, the number of remaining pages is set to h and the number of response pages is set to 21.

Finally, the flow of processing in this embodiment will be described with reference to FIGS. 4 to 6 together with the procedure for updating the page management table 9. When there is a screen display request for a certain work from the terminal 3, the terminal control device 2 judges that the first inquiry to the host 1 is necessary, and all of the first page case No. 14 to the record No. page No. correspondence information 17 are made. Set the initial value of zero to
The host 1 is inquired about the business name A from the first page to the first page (process 23 in FIG. 4 and blocks A to D in FIG. 5). Host 1
When the first page is received as response information 12 from the first page case No. 14 to the record No. page No. correspondence information 17 case No. 1, all are set to 1 and the first page is output to the terminal 3. , Inquires about the second to ninth pages from the host 1 (Fig. 4
Processing 24 and blocks A to H in FIG. 6). When the second to tenth pages are received from the host 1, the last page case No. 15 is set to 10, and the record No. page No. correspondence information 17 case No. 2 to case No. 10 is set to 2 to 10. Are sequentially set (process 25 in FIG. 4 and blocks A and J to M in FIG. 6). Now the first 10 screens are the terminal control unit 2
Has been accumulated in. Next, when there is a display request for the next screen from the terminal 3, the accumulated page range is calculated, and if the requested page is accumulated, the displayed page case No. 16 is updated by +1.
The screen of the relevant page is output to the terminal 3 (process 26 of FIG.
Blocks A and E to G of FIG. 5). Here the required page is 11
If it is the first page and exceeds the accumulated range, host 1
Inquires about one page from page 11 (process 27 in FIG. 4 and blocks A, E and H in FIG. 5). When the 11th page is received from the host 1, the first page case No. 14 is set as the second case, the last page case No. 15 and the currently displayed page case N are received.
With o.16 as the first case, the case No.1 of the record No. page No. correspondence information 17 is updated to 11, the 11th page is output to the terminal 3, and the 12th page to the 4th page to the host 1. Queries the minute (process 28 in FIG. 4 and blocks A to G in FIG. 6).
And I). When the 12th to 15th pages are received from the host 1, the first page case No. 14 is shifted to the 6th case, the last page case No. 15 is shifted to the 5th case, and the record No. page No. correspondence information 17 is set. 12 to 15 are set in the case No. 2 to the case No. 5 of (see process 29 in FIG. 4).
And blocks A and J to M of FIG. 6). That is, when the page break operation result exceeds 10 screens that have been accumulated, the entire 10 screens are not repainted in the next range, but only half of them are replaced.

According to this embodiment, even if the previous page request for the range of 5 screens before the update or the next page request for the updated 5 screens after the request for the previous page is made, the inquiry to the host 1 is made. Since it does not occur, the response time when the previous page request is requested can be shortened.

[0015]

According to this embodiment, the following effects can be obtained.

1. Within the range of the screen information stored in the terminal control device, the response time of the page break operation can be shortened by the host inquiry response time.

2. Even when a host inquiry occurs, it is possible to maintain the response time until the screen is displayed when the host makes an inquiry for each single screen.
