[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention provides a data reference system, a data reference method, and a data reference method for searching a database in which a plurality of pieces of related data related to an object are accumulated based on input predetermined trigger information and referring to related data of the object. A program for causing a computer to execute the method can be suitably used, for example, for construction management of construction or civil engineering work.
[0002]
[Background Art]
In recent years, with the rapid spread of computers, various information has been managed by database software. For example, in construction work and civil engineering work, map information, geological information, construction information, and their history information are configured as a database and provided for construction management, quality management, workmanship management, etc., so that efficient management is possible. Has been realized.
Such database software stores data in each database such as a map information database, a geological information database, and a construction information database in association with data in another database by a database management unit. Then, by extracting data necessary for management items such as construction management and quality control from data stored in the database as appropriate and displaying them in combination, the operator can refer to data corresponding to the target management item. You can do it.
[0003]
In addition, recently, such a database does not exist independently for each building construction site or civil engineering site, but is configured to simultaneously manage a plurality of building construction sites and the like. At a construction site or the like, necessary information is obtained by operating a terminal or the like to access a server in which a database is constructed. By doing so, it is possible to collectively manage information common to any site such as a member, a part name, and a construction machine as a master table. The changes can be reflected on all construction work sites and the like that are subject to management.
[0004]
Here, when referring to data in such database software, conventionally, an operator accesses a server equipped with a database with a terminal or the like, and sends character information such as a site name and management items to trigger information. As necessary data reference.
Recently, a reference method has been proposed in which two-dimensional map information is displayed on a terminal screen, and link information embedded in the map information is extracted by input means such as a mouse (Japanese Patent Application Laid-Open No. 2002-92084). Publication).
[0005]
[Problems to be solved by the invention]
However, in such a conventional reference method, it is troublesome to input character information, and a plurality of steps must be taken before necessary data is referred to, which requires a complicated procedure. .
In addition, in the technique described in the above publication, the operability is such that link information embedded in the map information can be extracted only by operating a mouse or the like by displaying two-dimensional map information. Although it is improved, it is still insufficient as a method for referring to various management items such as the above-mentioned construction management, quality management, and workmanship management.
[0006]
An object of the present invention is to provide a data reference system, a data reference method, and a program for causing a computer to execute the method, which can refer to necessary data corresponding to a management item by a simple operation.
[0007]
[Means for Solving the Problems and Effects]
In order to achieve the above object, a data reference system of the present invention displays a three-dimensional image related to a management target on a terminal, allows an operator to select an object constituting the three-dimensional image, and, based on the selected database, It is characterized by generating trigger information for search and outputting the obtained data.
Specifically, the invention according to claim 1 searches a database in which a plurality of pieces of related data relating to a management target are stored based on predetermined input trigger information, and refers to the related data of the management target. A data reference system that generates a three-dimensional image including an object constituting the management target for the management target, and selects an object in the three-dimensional image, A trigger information output unit for determining and generating trigger information corresponding to the object and outputting the trigger information; and receiving relevant information for receiving the relevant information of the object as a result of searching the database based on the output trigger information. Means, and related information output means for outputting the received related information.
[0008]
Here, the above-mentioned database is simply a database that records and stores related data to be managed, and has a different concept from a database including a database management system that manages input and output of data to and from the database.
Further, the three-dimensional image may be formed from three-dimensional data such as design data in the data to be managed or terrain measurement data, or may be created in advance in accordance with the management target, and stored in the database. It is good to save it as three-dimensional image data in the inside. Then, when a management target is specified on the terminal side, a three-dimensional image corresponding to the specified management target is called, and a three-dimensional image is generated on a display or the like on the terminal side.
[0009]
Furthermore, a three-dimensional image created in advance can be created using general-purpose three-dimensional computer graphics software, and can be created by applying texture mapping to a wire frame model. The three-dimensional image may be created by reading three-dimensional data such as design data and actual measurement data into general-purpose three-dimensional computer graphics software.
Further, it is preferable that the trigger information output means generates the trigger information in an XML (Extensible Markup Language) format when generating the trigger information on the selected object. The XML format script is a format that can be communicated on a general-purpose protocol such as HTTP (Hypertext Transfer Protocol) used on the Internet and the like, and furthermore, by defining its own document, various trigger information corresponding to the search item can be obtained. This is because it can be generated.
[0010]
According to the present invention, since the object selecting means presents the three-dimensional image and prompts the user to select a necessary object to be managed, the operator only needs to select an object in the three-dimensional image and to trigger. The information output means generates and outputs trigger information, and the related data of the object stored in the database can be referred to by the related data receiving means and the related data output means. Therefore, related data can be referred to by a simple operation without performing a complicated procedure as in a conventional search based on character information. Further, if the viewpoint of the three-dimensional image presented by the object selecting means can be changed, the operator changes the viewpoint of the three-dimensional image on the screen to display an object corresponding to the multifaceted management item to be managed. Can be.
[0011]
According to a second aspect of the present invention, in the data reference system according to the first aspect, history data representing a temporal change of the management target is stored in the database, and the management target is included in the stored history data. The object selecting means generates a three-dimensional image to be managed according to the time specified by the time specifying means.
Here, the designation of time by the time designation means is, for example, by displaying a bar representing a time axis on a screen of a terminal or the like, and selecting a predetermined position on this bar, allowing the operator to designate a time, In addition, a clock screen indicating the date and time is displayed, and an appropriate time can be designated, or various methods can be adopted.
[0012]
In this way, the object selection unit generates the three-dimensional image of the management target according to the time designated by the time designation unit, so that it is possible to refer to the relevant data relating to the object according to the time change of the management target.
For example, when the object to be managed is road construction at a predetermined site and there is data such as embankment as related data, even after the completion of the road construction, by specifying the time of the embankment work, the object selecting means can be used for the embankment construction. Since the inside three-dimensional image can be generated to prompt the selection of the object, the operator can easily select data related to the embankment work from the three-dimensional image.
[0013]
According to a third aspect of the present invention, in the data reference system according to the first or second aspect, the database is a database that stores information related to civil engineering or building work.
In civil engineering or construction work, management items are diverse such as process management, construction management, quality management, and finished product management, and there are many data stored in a database, such as design data, inspection data, and finished image data. Therefore, by adopting the present invention for management of such civil engineering work or construction work, it is preferable because necessary data can be referred to by simple operation for various management items.
[0014]
According to a fourth aspect of the present invention, in the data reference system according to any one of the first to third aspects, the trigger information output means is configured to generate a plurality of pieces of trigger information for the selected object. The data output means outputs a plurality of related data according to the trigger information.
Here, the plurality of pieces of trigger information to be generated include quality control data relating to the selected object, asphalt test results constituting quality control data, and road surface finishing conditions constituting work management data, among the work management data. And the like.
According to the present invention, for example, with respect to a selected predetermined object, photographic image data relating to a finished state representing a finished state and a test result at that time can be output from a related data output unit, and a reference system. Operability and the listability of related data can be greatly improved.
[0015]
The invention according to claim 5 constitutes the invention according to claim 1 as a method invention, and the invention according to claim 6 constitutes a program for causing a computer to execute the invention according to claim 5. .
Here, each procedure constituting the method invention does not necessarily have to be performed in the same computer, and a plurality of computers may cooperate to perform a series of procedures, Further, one procedure may be performed by a plurality of computers in cooperation.
And these inventions can also add the same limitation as the above-mentioned claim 2 to claim 4, and can enjoy the same action and effect.
In addition, since the method of the present invention can be implemented on a general-purpose computer by being configured as a program, it can be widely used.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows a site management system according to an embodiment of the present invention, which can manage various types of information on a construction site and a civil engineering site, and can refer to the management information as needed. This site management system includes a database system 1, a core system 3, and a data reference terminal 5 connected via the Internet 4. The predetermined reference request information transmitted from the terminal 5 is received by the database system 1 via the Internet 4, and the database system 1 acquires the request information from the core system 3 and returns the request information to the terminal 5 via the Internet 4. It is supposed to.
[0017]
The database system 1 includes a database management system 11, a database body 12, and an XML conversion unit 13.
The database management system 11 decodes request information and state change information arbitrarily input from the terminal 5 or the backbone system 3 (in this example, these are collectively referred to as event messages), and obtains one or different contact information. (In this example, referred to as an event object), and is stored in the database body 12 or an event object that meets the conditions for decoding the input event message is extracted from the database body 12. .
Here, the contact information is, for example, information indicating that an inspection after the process has been completed, an inspection of a finished product as a test, a test of compaction density has been performed, or a terrain measurement as a daily measurement of the finished product. This information indicates that the inspection and test data were registered in the inspection and test data database, and the inspection and test data registered in the inspection and test data database were used. The terrain measurement data can be registered in the terrain data database, and the terrain measurement data registered in the terrain data database can be retrieved.
The database management system 11 includes an event decoder / encoder 111, an event object generation unit 112, and an event object search unit 113.
[0018]
The event decoder / encoder 111 decodes the content of the event message input to the database system 1 and generates one or a plurality of different contact information.
The event object generation unit 112 is a part that generates an event object based on the contact information generated by the event decoder / encoder 111 and registers the event object in the database body 12.
The event object generation unit 112 generates an event object constituting an event message and also generates an association between the event objects, that is, a logical link.
[0019]
The logical link includes a synchronization link and a time axis link. As in the event message described above, a plurality of different event objects generated at the same time are related by the synchronization link and are the same type input at different times. Are linked by a time axis link. Note that these logical links are configured as bidirectional links that can be referenced from one to the other and from the other to one.
Then, the event object generation unit 112 generates an event object from the contact information generated by the event decoder / encoder 111, and associates each event object with a synchronization link, a time-axis link, and the like. Registration to the main body 12 is performed.
[0020]
When data request information or the like is input as an event message to the event decoder / encoder 111, the event object search unit 113 retrieves the desired event objects associated with each other by the logical link based on the result of decoding the event message. 12 is a part to be searched.
The event decoder / encoder 111 generates a predetermined event message based on the result and outputs it to the external terminal 5 or the like as a response result.
[0021]
The database body 12 is a part that records and saves the event objects generated by the event object generation unit 112 while maintaining the association of the synchronization link and the time axis link. Are recorded and stored in a series of event chains IC1, IC2, and IC3 associated with each other.
Further, in this example, the database main body 12 does not employ a configuration for directly holding the data DATA1, DATA2, etc. generated and stored in the core system 3, and employs the event chains IC1, IC2, and IC3. By linking an object (a rectangular unit on the right side of the event chains IC1, IC2, and IC3) and data stored in the core system 3, data in the core system 3 can be changed according to request information. It is configured so that it can be extracted immediately.
[0022]
The data structure of the database body 12 will be described more specifically. As shown in FIG. 2, the database body 12 is configured as a multi-layer database including a plurality of layers L1, L2, and L3, and is generated from an event message. The event objects F1, K1, D1, OP1, and N1 are recorded and stored in layers L1, L2, and L3 corresponding to the types.
Specifically, in this example, event objects N1, N2, and N3 related to construction are recorded on the layer L1, and each of the event objects N1, N2, and N3 is generated as a divided unit such as a construction section. In the layer L2, the process in each section is recorded as an event object OP1, and as time elapses, for example, processes such as spouting → leveling → compaction are recorded as an event object OP1, and are mutually linked by a time axis link. By performing the association, an event chain of the process OP1 is generated.
[0023]
In the layer L3, event objects F1, K1, D1, and Q1 related to the recorded photograph, the current terrain measurement data, the test data, the density measurement data, and the like in each process of the layer L2 are recorded, and the event objects F1, K1, D1, and Q1 are recorded. Are linked by a time axis link to form an event chain.
Simultaneous links are established between different event objects, for example, between the construction-related event object N1, the process-related event object OP1, and the related data event objects F1, K1, D1, and Q1. ing.
Then, a series of event objects of the same type connected by a time axis link is set as an event chain for the event object, and is recorded and stored as event chains IC1 to IC3 as shown in FIG.
[0024]
In this manner, by associating each event object with a link structure such as a stitch structure by a synchronization link and a time axis link, a data structure linked to each recorded event object can be obtained. It is possible to perform a multifaceted search at a high speed, such as simultaneous contact information of different types and time-series changes of the same kind of contact information, and it is possible to minimize the storage required for the database.
[0025]
It should be noted that, in the present example, a simultaneous link is not formed between different event objects in the same layer L3, but is not formed to prevent complication of the simultaneous link. It does not limit the formation of a simultaneous link.
Further, the layer configuration of three layers is also set for convenience, and is not limited to this example. The configuration can be arbitrarily set according to the configuration of the event message, the type of the event object, and the like.
[0026]
The XML conversion unit 13 converts an XML script used in the database management system 11 into a database language used in the backbone system 3 when performing communication between the database management system 11 or the terminal 5 and the backbone system 3. This is a part having a function of entering the message queue MQ and performing the reverse operation.
Specifically, the XML conversion unit 13 converts the HTTP of the database management system 11 into a predetermined protocol used in the backbone system 3 or converts the XML script into a script based on a language used in a database such as SQL. Or convert.
[0027]
The backbone system 3 is configured as a system for managing a plurality of management targets such as a construction site and a civil engineering site, and includes a plurality of management systems corresponding to the management targets. The above-described XML conversion unit 13 and the backbone system The communication is established via the interface 30.
The management system included in the core system 3 includes, for example, a quality management system, a workmanship management system, a construction management system, and the like. Different applications are adopted according to respective management targets, and management data to be registered is also included. A unique data structure is used.
[0028]
Specifically, as shown in FIG. 3, the database constituting the quality management system of the core system 3 classifies “work type”, “test item”, and “record data” set according to the site / construction section. It is configured as a hierarchical database with items. For example, in the "Construction type", "Lower subgrade", folders for test items such as "Consolidation density", "Pull flooring measurement", "Plate loading test", and "Sieving test" are set at the lower level. In the item folder, a “measurement condition file” that records the measurement conditions, a “measurement data file” that records the measurement results as numerical values, and a “photo data file” that records the measurement status as an image are stored. I have.
[0029]
As shown in FIG. 4, the database constituting the workmanship management system of the core system 3 includes “process”, “work type”, and “record data” set according to the site / construction unit as classification items. It is configured as a hierarchical data type database. For example, in the “paving process”, “lower subgrade construction”, “upper subgrade construction”, and “heated asphalt stabilization construction” are set as lower-level concept folders as work types, and the completed photographs of each work type are recorded data. Has been saved. For road accessories such as precast box culverts, guardrails, road signs, etc., information such as product names and manufacturer names of members used are stored as files in addition to photographic image data after construction.
[0030]
As described above, in the systems such as quality management and workmanship management that constitute the core system 3, appropriate applications are adopted according to the management target and the management items, and data is updated by operating each application. The database language converted by the XML conversion unit 13 from the XML script so as to be suitable for each application is received in the message queue MQ, and is input via the backbone system interface 30 to update the data.
[0031]
In this example, the data input to the backbone system 3 is held in the backbone system 3, and the event object relating to the recorded photograph of the layer L3 of the database main body 12, the current terrain measurement data, the test data, the density measurement data, etc. A link is established with F1, K1, D1, and Q1. Of course, it is also possible to record and hold these data directly in the database body 12.
[0032]
The core system 3 and the database system 1 do not need to be integrally configured as devices, and may be configured such that the database system 1 and the core system 3 are communicatively connected via a network such as the Internet. The various management systems constituting the core system 3 may also be independent systems, and each may be configured to be connected to the database system 1 via a network.
[0033]
A terminal 5 connected to such a database system 1 via the Internet 4 is equipped with a data reference system for referring to data recorded in the database system 1 and the core system 3.
This data reference system displays a screen G1 as shown in FIG. 6 on the display 7 to urge the operator of the terminal 5 to select a site at the site of construction / civil work. It is configured as a program that operates on an OS (Operating System) that controls the operation of the OS.
[0034]
The terminal 5 includes an input unit 6 such as a keyboard and a mouse, an input / output control unit 51 that controls input / output of the display 7, and a communication control unit 52 that realizes communication with the database system 1 via the Internet 4. The data reference system includes a time designation unit 53, an object selection unit 54, a trigger information output unit 55, a related data reception unit 56, and a related data output unit 57.
The program composed of these units 53 to 57 can be used by being downloaded from a WWW server provided with the database system 1 and installed on the terminal 5 composed of a general-purpose computer.
[0035]
The time designation means 53 urges the operator of the terminal 5 to designate a process or a construction time of a construction / civil engineering site to be referred to for data, and includes a time axis generation unit 531 and a time determination unit 532. I have.
The time axis generation unit 531 acquires the construction period of the site name to be managed specified by the terminal 5 from the database system 1 and, based on this, displays the time axis in a screen G1 as shown in FIG. A bar G11 is generated. The operator can designate a desired construction period or construction time by moving the pointer G12 formed on the time axis bar G11 with the input means 6 such as a mouse.
The time determination unit 532 monitors the operation status of the pointer G12 of the operator, determines which stage the operator wants information on the process, and outputs the determined construction period or construction period to the object selecting unit 54.
[0036]
The object selecting means 54 urges the operator to select which part or part of the predetermined construction site requires the relevant data, and includes a three-dimensional image generating unit 541 and a viewpoint determining unit 542. I have.
The three-dimensional image generation unit 541 is a part that forms a three-dimensional image G13 on the screen G1 in FIG. The three-dimensional image generation unit 541 generates a three-dimensional image G13 modeled according to a construction target at a designated construction site by calling it from a storage device of the terminal 5 or the like. This model image may be registered in the storage device of the terminal 5 in advance, or may be downloaded from a server provided with the database system 1 at the same time as the selection of the construction site.
[0037]
The three-dimensional image generation unit 541 is configured to generate a three-dimensional image G13 corresponding to the construction time specified in the time axis bar G11. For example, in the image G13, the image of the road completion time is used. Is generated, but when the initial construction is designated by the pointer G12, an image of an intermediate process such as a local business or an embankment process is generated.
Further, in the three-dimensional image G13, a selection object relating to a construction site and a selection object relating to ancillary equipment are embedded. By selecting this selection object, the operator can select a site or a site requiring related data. Select ancillary equipment.
[0038]
The viewpoint determination unit 542 is a part that monitors the operation of the input unit 6 by the operator and causes the three-dimensional image generation unit 541 to generate the three-dimensional image G13 of the viewpoint according to the operation. Specifically, when the operator selects an end of the three-dimensional image G13 with a mouse and drags the same, the three-dimensional image G13 rotates in the dragging direction. Thereby, the operator can display the state of the construction site from various viewpoints such as a bird's-eye view image, a side view image, and a cross-sectional image, and can select a necessary part.
[0039]
The trigger information output unit 55 is a unit that determines the selected object selected on the screen G13 and generates and outputs search trigger information for the database system 1 based on the selected object. The object determination unit 551 and the XML A conversion unit 552 is provided.
The object determination unit 551 is a unit that generates a part or a part name corresponding to the selected object selected by the operator. For example, when the mouse pointer is moved to the guardrail portion of the road on the three-dimensional image G13 and clicked, the object determination unit 551 is generated. 551 determines that the auxiliary equipment called “guardrail” has been selected in the three-dimensional image G13.
[0040]
The XML conversion unit 552 is a unit that generates an XML script for search based on the site name of the selected object determined by the object determination unit 551. The XML conversion unit 552 generates a search event message accepted by the database system 1. For example, if the operator says “I want to know guardrail specification data and recorded photograph data.”, “Guardrail”, “Specification data” , "Recorded photo data" and the like are surrounded by tags defined on the database system 1, and an XML script is generated.
Then, the XML conversion unit 552 transmits the generated XML script to the database system 1 via the communication control unit 52 and the Internet 4.
[0041]
The related data receiving unit 56 is a part that receives the answer result searched by the database system 1 based on the search event message output from the XML conversion unit 552. The related data accepting means 56 extracts a file surrounded by tags indicating the answer results from the answer results output as an XML script from the database system 1 as related data.
The related data output unit 57 is a unit that outputs a file included in the answer result received by the related data receiving unit 56 to the display 7 or a printer (not shown). When the file is displayed on the display 7, the three-dimensional image shown in FIG. The related data is displayed together with the three-dimensional image G13 in an empty area next to G13.
[0042]
Next, the operation of the present embodiment will be described based on the flowcharts shown in FIGS.
(1) When the operator activates the terminal 5 and accesses the database system 1 (process S1), the database system 1 transmits a site list screen of construction and civil engineering work managed by itself to the terminal 5, The operator urges the selection of the site where the related data is desired (process S2). The site selection screen may be displayed as a list as character information, or the site name may be displayed on two-dimensional map information.
[0043]
(2) When the operator selects a site, the terminal 5 converts the site name into an XML script and transmits it to the database system 1 (process S3). The database management system 11 of the database system 1 generates an event object related to the site name based on the received XML script, searches the database body 12 to obtain a series of event chains including the event object, and Basic information such as a name, a construction type, a construction section, and a construction period, and a three-dimensional image file corresponding to the construction type acquired from a three-dimensional image database set separately from the database system 1 are transmitted to the terminal 5 (processing S4).
[0044]
(3) When the terminal 5 receives the on-site basic information and the three-dimensional image, the data reference system is activated (process S5). The time axis generation unit 531 generates a time axis bar G21 as shown on the initial screen G2 in FIG. 10 based on the received basic site information (process S6), and the three-dimensional image generation unit 541 generates the three-dimensional image data. An image G23 is generated (process S7) and displayed on the display 7. In this example, in the initial screen G2, the three-dimensional image G23 displays the state before the construction, but this is a three-dimensional image created from the current state data obtained by measuring the terrain up to completion. Alternatively, a completed three-dimensional image may be displayed.
[0045]
(4) While the screen G2 is displayed, the time determination unit 532 monitors the status of the mouse operation of the operator, and the operator operates the mouse or the like to specify which time with the pointer G22 on the time axis bar G21. It is determined whether the process has been performed (process S8).
(5) When the specified time is determined by the time determination unit 532, the three-dimensional image generation unit 541 generates a three-dimensional image corresponding to the specified time and displays it on the display 7 (process S9). Specifically, the three-dimensional image generation unit 541 generates a three-dimensional image G33 under construction according to the position of the pointer G32 on the time axis bar G31, as shown in a screen G3 of FIG. It is displayed on the display 7.
[0046]
(6) While displaying the three-dimensional image G33, the viewpoint determination unit 542 monitors the operation status of the mouse of the operator and determines whether or not the viewpoint of the three-dimensional image G33 has been changed (process S10). When the viewpoint determination unit 542 determines that the viewpoint of the three-dimensional image G33 has been changed, the three-dimensional image generation unit 541 generates a new three-dimensional image based on the viewpoint (process S11). Specifically, in the three-dimensional image G33, when the operator clicks the right corner of the three-dimensional image G33 with a mouse, drags the mouse, and moves the mouse to the right, the three-dimensional image generation unit 541 causes the screen G4 of FIG. , A three-dimensional image G43 having a different viewpoint at the position of the predetermined pointer G42 on the time axis G41 is generated and displayed on the display 7.
[0047]
(7) With the screen G4 displayed on the display 7, the object determination unit 551 monitors the state of the mouse operation by the operator and determines which object in the three-dimensional image G43 has been selected. (Process S12). For example, when an object called a roadbed in the embankment process is selected, a specific object is selected by clicking an object G34 representing a roadbed area with a mouse pointer as shown in FIG. In addition, when performing the cross section selection in the embankment step, as shown in FIG. 12, the cross section can be selected by clicking the object G44 representing the cross section. In addition, when ancillary equipment such as a guardrail is selected, as shown in a screen G5 in FIG. 13, the user can select the object by clicking an object G54 indicating the guardrail on the three-dimensional image G53. When a structure such as a box culvert is selected, the structure can be selected by clicking an object G64 representing a box culvert on the three-dimensional image G63, as shown in a screen G6 in FIG. Although not shown in FIGS. 12 to 14, when these objects G34, G44, G54, and G64 are clicked, a submenu including character information is displayed on the spot. By further selecting, it is possible to narrow down related data of necessary objects.
