Thereby, it is also possible to acquire knowledge about the properties of the corresponding land and ground improvement. Hereinafter, embodiments of the present invention will be described in detail for each example.

FIG. 1 is a block diagram illustrating a ground strength diagnosis system according to a first embodiment.
The ground strength diagnosis system 10 is mounted on a server 16 connected to a user terminal device 12 via a network 14. The user terminal device 12 includes, for example, a display 2, a main body control device 3, a keyboard 4, and a mouse 5. A web page provided by the server is displayed on the display 2 by a browser. When the information regarding the designated land is input using the web page controlled by the server 16, the above diagnosis result is returned.

  In order to perform such control, the server 16 is provided with an arithmetic processing device 20 and a storage device 30. The arithmetic processing unit 20 includes a display control unit 21, a data input request unit 22, a database search unit 23, and a self-diagnosis unit 24. These means are computer programs that cause the computer of the server 16 to execute predetermined arithmetic processing.

  On the other hand, the storage device 30 stores databases such as a map database 26, a topographic map database 32, a ground improvement rate database 40, and an improvement performance database 50. In addition, data indicating specific contents of the ground classification 42 and the accompanying information 60 is also stored. The map database 26 includes a Japan map 27 and a prefecture map 28. The topographic map database 32 includes topographic map data 34 corresponding to the address 33. The topographic map data 34 includes a live-action topographic map database 35 and a model topographic map database 36. The ground improvement rate database 40 includes a ground classification 42 corresponding to the position coordinates 41 of the land and its ground improvement rate 43. The improvement performance database 50 includes the strength 52 of the ground already implemented at the corresponding address 33, the type 53 of the ground improvement work, and the cost 54. The ground classification 42 is stored in association with the place name list 46 and the commentary 47. The incidental information 60 is stored in association with the correction coefficient 61.

  The display control means 21 has a function of displaying the topographic map data 34 on the display 2 of the user terminal device 12. The data input request unit 22 has a function of requesting input of information specifying the address 33 and information specifying the position of the land on the topographic map data 34 displayed on the display. The database search means 23 has a function of searching the topographic map database 32 and selecting the topographic map data 34 in the vicinity of the corresponding address 33 when information specifying the address 33 is input according to the request of the data input request means 22. have.

  The database search means 23 has a function of searching corresponding data in the ground improvement rate database 40 when information specifying the position of the land on the topographic map data 34 displayed on the display 2 is input. The self-diagnosis unit 24 has a function of requesting the display control unit 21 to display the selected topographic map data 34 when corresponding data in the ground improvement rate database 40 is retrieved. Further, the search result of the ground improvement rate database 40 has a function of outputting a diagnosis result including the corresponding ground improvement rate 43 and the explanation 47 of the ground classification 42 to the user terminal device side.

FIG. 2 is an explanatory diagram of a screen example displayed on the user terminal device 12.
A specific operation method of the user terminal device 12 will be described with reference to the following drawings. A screen 70 shown in the upper part of the figure is a screen displayed at the start of diagnosis. The data input request unit 22 refers to the map database 26 and first displays a Japan map 27. When the corresponding prefecture is designated using the mouse 5 (FIG. 1), the database search means 23 searches the prefecture map 28. The display control means 21 thereby displays a screen 74 on the lower side of the figure. Here, an address is designated using the address input window 76. Note that the address input window 76 may be displayed from the beginning to directly specify the address.

  When a specific address 33 is designated, the database search means 23 (FIG. 1) searches the topographic map database 32 and searches the corresponding topographic map data 34. If there is an aerial photograph of the area including the address, the photographed topographic map database 35 is retrieved and displayed. If there is not, the model topographic map database 36 prepared in advance for the area including the address is displayed. The photographed topographic map database 35 is a bird's-eye view image such as an aerial photograph obtained by actually photographing a land. The model topographic map database 36 is a bird's eye view image in which a representative topographic map is virtually displayed. A planar image such as a satellite photograph may be used, but a so-called 3D image is preferable. It should be noted that it is not easy to prepare the model topographic map database 36 so as to adapt to the terrain of all regions. Therefore, for example, several kinds of typical things such as a place with a river, a place with a sea, a city, a mountainous area, etc. may be prepared, and one of them may be selected and displayed. The user may select arbitrary topographic map data 34. The topographic map data may be a still image or a moving image. For example, when a bird's-eye view or a longitudinal sectional view of the corresponding land viewed from a plurality of directions is displayed, the user can recognize the land more objectively, so that the state of the corresponding land can be clearly identified.

FIG. 3 is an explanatory diagram of an example of the topographic map data 34.
As shown in the figure, when the topographic map data 34 is displayed on the display, the user operates the mouse 5 (FIG. 1) and designates the target land with the cursor 77. If the designation of land is not clear in this figure, you may want to redisplay an enlarged view or a view from another angle. If the topographic map is detailed and specific, the structure and properties of the corresponding land can be accurately grasped from the position designated by the cursor 77. For example, when designation is made on the fan-shaped land in the figure, on the natural levee, on the delta, or on the reclaimed land, the ground classification 42 corresponding to the position coordinates 41 of the land is referred to the ground improvement rate database 40. Can be identified automatically.

  When the topographic map data is displayed on the display and the position is designated by the cursor 77, the relative position coordinates on the screen are acquired. The position coordinates of the corresponding land are acquired from the relative position coordinates. For example, the topographic map data is divided into small areas by focusing on the ground classification. When a position included in a certain range is designated, a ground classification corresponding to the range is specified. Therefore, the position coordinates for specifying the ground classification may be displayed in one or more areas. In order to specify the position of the land, various pointing devices such as a digitizer and a touch panel can be used instead of the mouse 5 (FIG. 1). Further, for example, numbers and symbols displayed on the map may be specified using a keyboard.

FIG. 4 is a data explanatory diagram showing the relationship between the ground classification and the ground improvement rate.
As shown in FIG. 1, the ground classification 42 is expressed in easy-to-understand words in the place name list 46, and further explained in detail in the explanation 47. For example, if the ground classification is “landfill,” “the landfill is a land that is artificially created by stacking a large amount of waste, dredged soil, construction soil, etc. There is a danger of liquefaction. Where the clay layer is thick, the ground becomes soft. As a result, the user can understand the nature of the designated land and know the grounds for the necessity of ground improvement. Detailed technical data may be stored here. This can be used as a reference for experts who have received a survey request from the user for ground improvement.

  The ground improvement rate database 40 (FIG. 1) further stores a ground classification 42 and a ground improvement rate 43 in association with each other. As shown in FIG. 4, the ground improvement rate 43 of the corresponding land is indicated by a numerical value (%) for each ground classification 42. The ground improvement rate 43 is the ratio of ground improvement in the past for the ground of the classification. For example, in the case of a landfill, information indicating that ground improvement work has been performed in the past is provided for 60% of the actual surveys. The user makes a decision to make a ground survey just in case. Note that a general property of the ground may be added to a part of the ground classification 42. An example of this is shown, but such information may be included in the comment data or displayed at an arbitrary location.

5 and 6 are explanatory diagrams of incidental information.
There are various circumstances in each user's individual land. Ground classification alone from the topographical map may not be enough. For example, it is assumed that a natural levee in a river basin is designated as a target using FIG. At this time, an enlarged view as shown in FIG. 5 may be displayed to specify a more specific position. This is because it is difficult for general users to distinguish between natural dykes, back marsh and terraces. More specifically, it is preferable to specify a more specific position by displaying various structures such as artificial embankment drawings, lakes, and irrigation canals.

  In addition, for example, as shown in FIG. 6, it is preferable to take the circumstances into consideration in the case of a slope or a land that has been cut or filled. Locations A and B may have different ground strengths. In other words, more accurate results can be provided in consideration of information representing the nature of land that cannot be classified by ground classification. For example, according to FIG. 4, the ground improvement rate in the hilly area is 10%, but in the case of the embankment that has been created, correction is made such that it is 20%. As shown in FIG. 1, this correction may be calculated using data in which the incidental information 60 and the correction coefficient 61 are associated with each other. The self-diagnosis means 24 (FIG. 1) may automatically execute such arithmetic processing.

FIG. 7 is an operation flowchart of the above system. FIG. 8 is a sequence chart thereof.
Hereinafter, an embodiment of a computer program for controlling the server 16 will be described. The above system is processed in a procedure as shown in FIG. 7 or FIG. 8, for example. First, as shown in FIG. 8, the user operates the user terminal device 12 to start the program of the server 16. The display control means 21 displays the Japan map 27 on the display of the user terminal device 12 (step S11). In step S12, the user designates a prefecture. The data input request unit 22 detects the button click event. In step S13, the corresponding prefecture map designated by the display control means 21 is displayed.

  In step S14, the data input request unit 22 displays an address input window 76 on the display. Then, the address data is acquired. In step S15, the database search means 23 searches the topographic map database 32 and acquires corresponding topographic map data. The display control means 21 displays the topographic map data on the display of the user terminal device 12 in step S16. When the target land is designated by the user terminal device 12, the data input request means 22 detects the mouse click event in step S17. In step S18, the relative position coordinates are obtained on the screen. The database search means 23 calculates the position coordinates of the land from the relative position coordinates in step S19. Using this result, the ground improvement rate database 40 is searched in step S20. Thus, in step S21, data corresponding to the explanation of the ground improvement rate and the ground classification is obtained. The result is passed to the self-diagnosis means 24. In step S <b> 22, the self-diagnosis unit 24 edits the result and displays it on the display of the user terminal device 12.

FIG. 9 is an explanatory diagram of an output example of a diagnosis result.
As shown in the screen 81 in the figure, the address 33 input by the user, the ground classification 42 specified by the user's designation, its explanation 47, and the ground improvement rate 43 are displayed as a result. In addition, how much the ground improvement rate 43 is corrected and taken into consideration according to the incidental information input by the user is also presented. The data input by the user and the result thereof may be temporarily stored in the storage device 30. When the user requests an estimate, the button 82 is clicked. When the user makes a ground survey request immediately, the button 83 is clicked. In any case, the data temporarily stored in the storage device can be transferred to the sales staff for effective use. In addition, if a function for adding data input by the user and the result thereof to the database is provided, specific data indicating the relationship between the address and the structure and properties of the land can be accumulated. This can be used, for example, for accumulating information on areas where there are many inquiries and improving the accuracy of answers.

  In the above system, for example, if all the structures and properties of land at all addresses are stored in the database, when the user inputs the address of the target land, the need for ground improvement can be easily explained with documents. it can. However, such a database does not actually exist and is difficult to realize. An aerial photograph alone cannot accurately grasp the structure and nature of individual land. Of course, there are many places without aerial photographs. Therefore, in the above embodiment, when an address is specified, a schematic topographic map of the area is displayed, and the user directly inputs the position of the target land on the map.

  If the topographic map is detailed and specific, the structure and properties of the corresponding land can be accurately grasped from the designated position. If information that the user notices is added to the incidental information, it is possible to diagnose the necessity of ground improvement for the land with high reliability. Through such work, the user can re-recognize the state of the target land and at the same time recognize the meaning of the past ground improvement rate.

  In the above system, the storage device 30 and the arithmetic processing unit 20 of the server 16 may be built in the server 16 or externally attached. The storage device 30 stores web data that can be browsed by the user terminal device 12. The web data is rendered in a state where it can be browsed through a network using a predetermined URL (Uniform Resource Locator). Web data is created in formats such as HTML (Hyper Text Mark-up Language), SGML (Standard Generalized Mark-up Language), XML (eXtensible Markup Language), etc. It is.

  Web data includes VBScript (Visual Basic Script: a programming language developed by Microsoft), Java (registered trademark) (a programming language developed by Sun Microsystems), Java (registered trademark) Script (Sun Microsystems and Netscape Communications). A computer program written in a script language developed by the company is included, and a predetermined process is executed on the browser.

  The computer program installed in the arithmetic processing unit may be configured by combining independent program modules, or may be configured by a program that is integrated as a whole. All or part of the processing controlled by the computer program may be configured by hardware having equivalent functions. Further, the above computer program may be used by being incorporated into an existing application program. The computer program for realizing the present invention as described above can be recorded on a computer-readable recording medium such as a CD-ROM and installed in any information processing apparatus for use. It can also be downloaded and used in the memory of any computer through the network.
