Abstract

PURPOSE:To simplify the setting work of a retrieval object by taking not a symbol mark but a character itself as the retrieval object. CONSTITUTION:In a retrieval system, a data retrieving machine 50 is connected to a host computer 10 through a communication line L. When not a symbol mark but a character is taken as the retrieval object, the coordinate area is indicated by 24X24n dots in the case of n characters, and the coordinate management is possible. Since the coordinate area is detected by the cursor position of the start of the character write time, inputted characters are regarded as one character string and characters and their coordinate area are stored to set a character as the retrieval object when the character is only inputted to a desired position on a display picture. Thus, the setting work of the retrieval object is facilitated to improve the work efficiency.

6. If you want to know, for example, the name of the product in the product tank and its remaining amount from the displayed diagram, you can use the mouse to Operate...1 screen-1-
Move the cursor to the symbol mark indicating the product tank with the search sentence and one image! - By operating the confirmation button on the mouse, data for the product tank is retrieved from the data source and displayed on the screen. In this way, drawing data and database are linked,
Data searches can be performed by making database data searchable from the display screen.

[Problem to be solved by the invention]

In the above data search system, the area of the symbol mark (for example, Q△[]◎) indicating each device to be searched is represented by the coordinates of the display, and each of these coordinate areas is identified. , a unique code (e.g. 1,
2.3, 4) are given, and the coordinates and the corresponding code are stored in a RAM or the like as shown in Table 1. On the other hand, using the above code as a search word (headword),
Detailed data corresponding to this is registered in the database. When the above-mentioned confirmation button is pressed during data search, if the cursor is in any coordinate area, -ζ'' is located = 2. Recognizes the area, and if the area is found, responds. J-1 or 1'l ] From the database based on this Nihu l.
・Information about ・is now read out. Therefore, in order to perform a data search using the system described in 1.
It is necessary to set in the system that each formal mark is the search target, and to do so, it is necessary to correspond to the displayed test element χ by examining the coordinate area of the elephant. Since symbol marks come in various shapes and are very human-like, it is necessary to register them in RAM along with the code to create new drawing data and the subsequent When modifying drawing data, the search target setting work that had to be done was complicated.Also, it was necessary to set a unique hood (-=1) for each search target. In order to avoid adding incorrect codes, the symbol and this i:”,
2. It was necessary to record the corresponding codes and manage the codes using a comparison table. Furthermore, even when creating a database, it is a search word or a meaningless code, so the error -i
-<:,: Register the data corresponding to 1-1 of Sl and l and register 11. [MaT] Sa (,) 2, Ta, - could have happened 1, Child - Enduring If 294ζ U1. -1 In the conventional version 7-no, when creating a new drawing data and after maintenance BJ (required search/1 image settings) 1.1 The present invention has been made in order to solve the problems mentioned in 1. [5], and it facilitates the task of setting the search target. The purpose is to provide l-4.

[F stage for solving the problem] The present inventor has solved such drawbacks.
The present invention was completed by paying attention to the fact that the area occupied by (for example, 24x24 dots) is constant, and by making the characters themselves displayed on the screen 2+1 the search target. , In other words, if the search target is 1 character without the symbol mark C, if it is 1 character, the coordinate area is 24〉((24+
1) It is expressed as l / /t, making the coordinate contradiction easier, and in history,
The coordinate area can be known from the cursor position at the start of character writing, so either manually input the characters on the display screen at the desired position, or use i'l to combine the input characters with a string of -, 1, and 1. , the character and the character's 14 < stored in the memory 1-level, the character can be set as the search target, ]-11, and as a result, the coordinates as described in 4 and 5 above can be set. It is possible to eliminate the region recognition task by 4'. . If you want to set the search target to the characters "Pump 1" that are displayed from the beginning on the screen, in this case, "Pump 1"
Since the coordinate area of is -2, it is 1, 'pump 1'
or a single string (
, shi is sufficient, so 14゛ can be easily equalized by specifying the area at both ends of the character with the cursor.
. In addition, if the drawing data already contains the character string to be searched and the coordinate area of that character string (6-), the system automatically recognizes that character string as the search target by 1,5C recognition [1, character Coordinate areas of columns and character strings are stored in a storage means.

As shown in Table 2, 1 and 17 are equipped with a character to be searched, a coordinate area of the character, and a RAM 13B that stores 7. This database stores 4'' data corresponding to each search word. 150 is the communication line 1. This is a data retrieval device connected to a computer (host)=vnviewer 101 via a terminal device)'j1, a memory 52, a display device, a keyboard ξ]4, and a mouse 55. , Terminal E) 1 (This is a ROM that stores the program for the t'-day search described later.)

Then, proceed to steps 5IO1S20 and S30. In the case of setting mode 1, in step Sll, the drawing data is read from the drawing file 16 and the drawing data is stored in the memory 14.
is displayed on the display 11. Assuming that there is a device name “Honda 1” near the pump mark displayed on the screen of the display 11,
In order to search for this device name, in step Sll,
The first letter "bo" and the last letter "1" of this device name are specified in an area using the keyboard 54 or the mouse 55 with a cursor. . Next, when the "execute key" is pressed r, the process proceeds from step S1.2 to step S13, where the computer 13 recognizes the designated initial letter to final letter as one character string. In step S14, the coordinate area is recognized from the display position of the characters "Pump 1", and in Step S15, the coordinate area is recognized as "Pump 1".
As shown in Figure 4 (A) or Figure 4 (B), the character string and its coordinate area are the coordinates of two diagonal points (x, 1. y +), (x, 1 yt ) is RAMI,
Stored in 3B. In step S16, it is determined whether this setting mode 1 is finished or not, and if registration is to be continued, the process returns to step Sll, and the search target settings are made in the same manner, or this setting work is ended. In this case, go back to step S1. Next time, when creating new drawing data, add the symbol mark of the device in steps 1 and 2 to the drawing data registered in registration mode 1, and enter the device name in step 5. Setting mode 2 of step S20 to be set as a search target will be described. First, in step S21, the cursor is moved to the writing position (1-7), and in step S22, the device name is written on the display screen. Once you have entered the characters, press the execution key in step S23, the process will proceed to step S2.1, and as described above, the device name written in the command will be recognized as a character string, and in step S25, the The coordinate area of the character is recognized from the cursor position when writing the character, and the character and its coordinate area are stored in the RAM 13B in step S26. If this setting mode 2 is to be continued, the process returns to step 321, and if it is to be terminated, the process is returned to step S1. Finally, we will describe the procedure for erasing a search target that has already been set as a search target. In this case, in step S31, move the cursor to the location of the device name you wish to erase, and in step S32, erase the characters of the device name by operating the "erase key".
By operating the "execute key" in step S33, the device name is erased on the display Il in step S34, and the device name and its coordinate area stored in RAM I3B are also erased.Step S35 Based on the determination, if this erase mode is to be continued, step S
31, and when finished, return to step S1. Through the above operations, the characters displayed in the drawing data from the drawing file 16 called into the memory 14 are stored in the RAM 13B as search targets. Further, it is assumed that data corresponding to the contents stored in the RAM 13B is registered in the database 17 using the above-mentioned characters as search words. Note that the registered data may be data based on character information, or may be other drawing data corresponding to the search word. Next, data retrieval in this system will be explained with reference to the flowchart of FIG. In step S4.1, a data search command is issued from the data search machine 50, and in step S42, the drawing data stored in the memory 14 of the host computer 10 and the data stored in the RAM 13B of the computer 13 are retrieved. Characters to be searched and their coordinate area data, or
The drawing data is loaded into the memory 52 of the data search device 50 and the RAM 51B of the terminal 51 and displayed on the display 53. In step S43, specify the character you want to search with the cursor and turn on the execution key.
The process then proceeds to step S45, where a coordinate area including the cursor position is selected from the RAM 51B by the following method. The coordinates of the cursor position at this time are (x, o, y o
), for example, if X1≦X, ≦X2, yl≦yo≦y, the cursor position is in the coordinate area (x
+, yυ(X!, yt). In the next step S46, the character "Pump 1" corresponding to the selected coordinate area is read out from the RAM 51!3.
In step S47, the characters "Pump 1" is the search word are sent to the post computer 10 as L7. As a result, when the host combination 10 side receives the search word of the characters "Pump 1°", it proceeds from Step 5100 to Step 5101 and searches the database using "Pump 1" as the search word. ), the corresponding data is read from the database, and the contents are sent to the data search machine 50 in step 5102. In the data search fi 50, the host computer 10
When the search data from is received, the process advances from step 848 to step S49, and the received search data is
3. If this search mode is to be continued, the process returns to step S43, but if it is to be terminated, the process is ended in step S5]. Although the present invention has been described as being applied to P&HD, the present invention can also be applied to general map search devices and the like. There is also a system configuration that has the functions of both a host computer and a data search machine, as shown in FIG. Table 1 Table 2 [Effects of the Invention] As explained above, in the present invention, the search target is not formal marks but characters and symbols themselves, so it is easy to manage the coordinates of these characters and symbols, and the display area or writing The system can automatically recognize the coordinate area of characters and symbols based on the cursor position, simplifying the process of setting search targets. In addition, in databases, since letters or symbols were used as search words, conventionally,
It is unnecessary to add a code to identify the search target, and by interposing the code between the search target and the search data, there is no need to worry about the two data being mistakenly linked.
