FIG. 2 is a system block diagram showing the overall hardware configuration of the sewer laying design support system according to one embodiment of the present invention. In this example, a personal computer (PC) is used as a host computer 1 that mainly performs sewer installation design support in the system, and a CPU (central processing unit) 2, a system memory 3,
An external storage device 4, an input operation device 5 having operators such as a keyboard and a mouse, and a display device 6 such as a display;
These devices 2 to 6 are connected to each other via a bus 7.

The CPU 2, which controls the entire system, performs various controls in accordance with a predetermined program, and particularly, centrally performs processing for supporting sewer laying design according to the present invention. The system memory 3 includes a basic program,
Programs and fixed data related to sewer laying design support
A ROM (read only memory) storing parameters and a RAM (random access memory) for temporarily storing various data are provided.

Further, the external storage device 4 is composed of a storage device using a storage medium such as a CD-ROM / FDD (floppy disk) / MO (magneto-optical) disk in addition to a hard disk drive (HDD). It stores programs related to support and various data / parameters. The external storage device 4 also has a data filing function for various databases and libraries, and can construct various databases and libraries for supporting sewerage installation design.

The input operation device 5 includes a display 6
By operating a predetermined key of the keyboard or designating an operation button on the display 6 with a mouse or the like while visually recognizing various screens displayed on the screen, various processes for supporting sewer laying design can be performed.

The bus 7 has an interface 8 for acquiring actual terrain data (three-dimensional coordinates), an actual measurement terrain data input device such as a computer 9 for the site, and a digitizer system 10 and a scanner system 11. A drawing data input device and a paper document output device such as a printer (for example, a color laser printer) 12 and a plotter (for example, a color inkjet plotter) 13 are connected.

In order to grasp the current situation of a site where a new sewer pipe is to be laid (buried), the GIS (Geographic Information System) that can be used by a design builder can be used around the site.
m) In many cases, the map data and attribute data already obtained in step (d) are used. However, since the current situation changes moment by moment, the construction site and its vicinity are monitored using the on-site computer 9 etc. It is preferable to acquire the latest current plan data. The on-site computer 9 is, for example, a portable personal computer using device called an “electronic flat plate”, and includes a total station (TS) 14 and a GPS (Gl).
obal Positioning System: A digital surveying device such as a device 15 is a wireless device 16, 17; 1
The communication lines 8 and 19 are communicably connected, and an automatic contour line generation function is provided by application software.

The total station (TS) 14 is an external business machine installed and used on a tripod at a surveying site.
The angle and distance are obtained from the time when the light emitted from the illuminator is applied to the reflection mirror at the measurement point and returned, and the three-dimensional position coordinates are digitally measured. In the latest TS model, there is a non-prism type that does not require a prism. In addition, the GPS 15
This is a digital geodetic device based on the PS system. Due to the remarkable progress of recent technology, it has been downsized, the measurement operation is easy, the equipment is very simple, and the digital three-dimensional position is extremely accurate in a short time. Since coordinate data can be obtained, it is used when high-precision surveying is required because there is no high obstacle (curtain) such as a high-rise building around the surveying point in GPS surveying.

The digital survey data from the TS 14 or the GPS 15 is transferred to the site computer 9 by radio (or transmission line), and the program determines three-dimensional coordinates of each survey point (generally several hundred to 1,000 points).
Contour data is automatically generated. At the same time as the measurement,
By repeating the operation of inputting the attributes of points such as telephone poles and sidewalk edges, the on-site computer 9 can also generate current state map data (three-dimensional coordinates) on the screen.

On the other hand, in order to grasp the underground buried object already buried in the site, the GIS which can be used by the design builder is used, or a desk survey or a test excavation survey is carried out. Get current status data. In the case of a desk survey, a drawing reader such as the digitizer system 10 or the scanner system 11 can be used. The digitizer system 10 is a "digital tracer"
This is a method of reading drawing data of a paper drawing into the host computer 1 by tracing the drawing with a remouse, and reading only necessary objects. Therefore, only a part of the equipment drawing is read. It is suitable for the case, and the attribute is input simultaneously with the reading of the object.

The scanner system 11 is also an input device for taking a paper drawing into the computer 1. Since the scanner system 11 reads everything described in the drawings, it is suitable for reading accurate equipment drawings based on actual measurements, such as equipment drawings of a power company. When the scanner system 11 is used, a procedure is adopted in which all the drawings are once read and then attributes are given to only necessary parts. Therefore, which one of the digitizer system 10 and the scanner system 11 is used depends on the function and purpose.

The host computer 1 uses the input data from the input devices 9 to 11 to operate the input operation device 5 with the display assistance of the display 6 to obtain the respective steps ST1 to ST6 of FIG. Performs various processes for the tasks shown in. The product data obtained as a result of various processes by the host computer 1 is stored in the printer 1
2 and a plotter 13 are output as drawings and tables.

FIG. 3 is a functional block diagram schematically showing functions of a sewer laying design support system according to one embodiment of the present invention. In the investigation stage ST1, the host computer 1 mainly uses the current state observation data by the on-site computer (electronic flat plate) 9, as shown in the functional block A of FIG. Then, the latest digital plan data is obtained. That is, via the on-site computer 9 (or
Direct) Receiving digital survey data of each measurement position sent from surveying devices 14 and 15, determining three-dimensional coordinates of all survey points, automatically generating contour data, and generating current plane data through attribute input work. . When the current state map data (three-dimensional coordinates) generated by the on-site computer 9 is received, this data can be output as it is as the current state plane data.

Next, as shown in the functional block B, the host computer 1 traces the already buried underground object from the existing drawing by using the drawing readers 10 and 11, and traces the buried equipment. Type and its position
Obtain data on the existing underground buried objects including information such as depth. The acquired existing underground object data is additionally input to the existing plane data, and the figure is edited using the input operation device 5 with the assistance of the screen display on the display 6 to correct the underground object data. Then, it is made to correspond to the current plane data accurately.

Subsequently, in the design stage ST2, the host computer 1 creates various design data according to the sewerage floor plan, as shown in the functional block C. In other words, in consideration of the current plane data generated by the on-site computer 9 or the function block A and the relationship with the existing underground buried object obtained by the function block B, the laying route is set / determined to create the plan data. I do. For example, based on the design conditions of the sewer to be laid, the pipe laying route and the manhole / mounting pipe are set, and the plan of the floor plan and the longitudinal plan are designed. In such a design work, the function block C2
As shown in the figure, each time the laying route is set, the flow rate is automatically calculated, and the calculation result can be tabulated and output as required by the printer 12 as a pipe network flow rate calculation as shown by a broken line (broken line). Means the following functional block D
-N). As a result, when it is finally confirmed that the design content meets predetermined conditions in the sewer laying design, the laying route is determined, and the corresponding plane and longitudinal plan data are created.

In the design stage ST2, as shown in the functional block D, various planning drawings are plotted and output by the printer 12 or the plotter 13 from these planning data, and are used for manhole assembly members and earth retaining members. The type of sheet pile to be executed is automatically calculated, and various quantity calculation reports and the like are created.
When laying sewer pipes by the propulsion method, steel sheet piles,
Temporary structural drawings such as a liner plate and a vertical shaft for a propulsion method using a main shaft horizontal sheet pile are also created. These charts can be output on paper from the printer 12 or the plotter 13 as required, as indicated by the broken lines. When the color inkjet plotter 13 is used, the final result drawing can be output in color at the maximum size. And
Various data obtained in the design stage ST2 is stored in the external storage device 4 provided in the host computer 1.

After completing the design stage ST2 by performing such design and quantity calculation, enter the permission application work stage ST3 indicated by the functional blocks E and F before the construction stage ST4 of the underground laying sewer based on the design result. Documents such as "Application for Road Occupation Permit" and "Application for Permission to Use Road" to be submitted to the competent management and supervisory authority are automatically created from the plan data in order to obtain permission for the construction of sewerage. That is, in the functional block E, in order to occupy the road when laying the sewerage, a road occupation permission application and the like to be submitted to the manager / institution of the road with the underground sewage (national or local government (local office), etc.) Create In the function block F, a road use permit application to be submitted to a road supervising agency (prefectural police station) to use the road and an attached document such as a traffic countermeasure map are prepared. Here, the plan data obtained in the function block D can be used as it is for creating the attached document.

When the permission application is passed, the operation proceeds to the construction stage ST4. Based on the plan data and the change instruction for the application, the computer 1 creates a construction drawing according to the sewer to be finally constructed as shown in a functional block G. create. Based on the construction drawing, the laying of sewerage is performed and the construction stage is completed.
5, when the laying work passes the inspection and is completed, the computer 1 reflects the contents changed during the construction of the sewerage in the construction drawing as shown in a functional block K, creates a completion drawing, and calculates the completion I do. The completed drawing is further prepared into a sewerage facility diagram suitable for subsequent management as shown in a function block M, stored in a sewerage facility database (document cabinet) of the external storage device 4, and used for subsequent management. You. Then, the management stage ST6
Then, as shown in the functional block N, the computer 1 links the sewerage facility diagram data stored in the sewerage facility database with the GIS system and the drawing management system, and links the sewerage facility diagram data with these systems so that the computer 1 is related to the sewerage laying work. Support the life cycle of various drawings and forms.

[Processing Flow Example] FIGS. 4 and 5 are flowcharts showing the overall processing flow of the sewer laying design support system according to one embodiment of the present invention.

[Survey Stage: S1 to S3] Step S1
Then, when the current topography is digitally surveyed by the surveying devices 14 and 15, the survey result is sent to the host computer 1 via the on-site computer 9 and the like, and digital survey data (D1) representing the current topography is obtained. In the next step S2, the current state map data (D2) is obtained based on the digital survey data (D1), and the current state map data (D2) is stored in the topographical database of the external storage device 4 provided in the host computer 1. DB1 (FIG. 7)].

Next, in step S3, data of an existing underground object of another kind (D3) is created. For this purpose, for example, a facility ledger diagram of a company managing the existing underground buried object at the construction site is used, and if there is GIS data, it is used. Power pipes,
There are telephone pipes, water pipes, gas pipes, and other buried objects, including the existing sewers.

Here, a method of reflecting the existing telephone equipment by the digitizer system 10 will be described. In this method, a telephone equipment drawing is set in the digitizer system 10, and first, an operation of matching the positional relationship between the current drawing generated by the host computer 1 and the telephone equipment drawing set in the digitizer system 10 is performed. That is, using the mouse (5), two points of the current state drawing and two points of the telephone equipment drawing [for example, a manhole, a corner of an intersection, etc.] are matched on the screen of the display 6 on a computer, It is assumed that both drawings are superimposed. In this superimposition work, the function to automatically change the scale is used,
Superposition can be performed even on drawings having different scales.

Subsequently, the object to be reflected in the telephone equipment drawing set in the digitizer system 10, ie, the object to be reflected,
Click on the telephone line with the mouse. Normally, the telephone pipeline is in a state only appearing on the screen as a picture, so the input screen is opened and attributes (for example,
Pipe material ("vinyl pipe" etc.) and pipe diameter ("100mm"
), Earth covering (“0.5 m to 1.0 m” etc.)]. Through this repetitive editing operation, telephone pipe current state data is obtained, and the telephone line is superimposed on the current state drawing to create a drawing in which the burial route of the telephone pipe is entered.

Next, a method of reflecting the survey result of a buried object by the scanner system 11 will be introduced. First, when the water supply equipment drawing obtained from the waterworks bureau is read by the scanner 11, the status of reading by the scanner is displayed on the screen of the display 6. When the reading of the drawing is completed, the read water supply equipment drawing is subjected to necessary processing such as drawing cleaning and drawing distortion correction, and the same two points are compared with the existing drawing already created on the computer. Overlay using the automatic scale change function.

When the two drawings overlap, an input screen is next opened, and the user clicks on the water pipe to be given an attribute, and the attribute (for example, pipe material ("steel pipe") or pipe) is added to the water pipe. Diameter (“200 mm” etc.), earth covering (“1.2 m to 1.5
m ”)]]. By repeatedly acquiring the water supply status data (D3) by this editing work, the data of the water supply facility diagram is superimposed on the current status diagram to create a drawing in which the water supply laying route is entered. can do.

Regarding gas pipes, power lines, and other buried objects, the same operation is performed with the existing drawings,
Existing underground buried object status data (D3) can be acquired. These existing underground buried object data (D3)
If it is raster data, it is vectorized by a vector conversion engine as necessary, and is divided into layers for each existing underground buried object status data, and the raster data or DB is stored in the buried object database [DB2 (FIG. 7)] of the external storage device 4. It can be stored in the form of vector data. Then, the existing buried object reflection diagram data (D4) is created by reflecting all the buried object current state data in the current state diagram data (D2). At the same time, current cross section data (D5) and current cross section data (D6) are created, and these data are also stored in the buried object database (DB2).

[Survey Step: S4 to S9] Following Step S

In 6, the pipe bottom height or gradient is automatically calculated based on the plane and longitudinal plan data set in step S5 according to numerical values and calculation conditions such as the flow rate calculation method set in step S4, and the pipe network flow rate is calculated. Automatic calculations are performed. As a result, the set flow rate set by the plan data is obtained, and the calculated content can be tabulated and output from the printer 12 as a pipe network flow rate calculation report (D90).

(4) Design data verification (S7): In the next step S7, it is determined whether or not the set flow rate calculated in step S6 is equal to or less than a permissible flow rate predetermined by a set flow rate calculation method. If the suitability for a predetermined standard is determined and the suitability is confirmed to be equal to or less than the allowable flow rate, the process proceeds to step S8, and if not, the process proceeds to step S5.
Then, the floor plan data and the vertical plan data are input again to set the laying route again. Steps S5 to S7 are repeated until the set flow rate becomes equal to or less than the allowable flow rate.

(5) Determination of Route and Design of Auxiliary Equipment (S8): In step S8, a route for laying a sewer pipe is determined, and various plan drawings are created based on the determined plan data in accordance with the set drawing conditions.

In this step S9,
Work section work data for construction work of sewer sewers for each work section planned in advance according to the floor design drawing route (D18)
Is also created.

[Application Stage: S10 to S13] Subsequently, the process proceeds to steps S10 to S13 to perform a task for applying for permission for private use and use of the road. First, in step S10, data necessary for applying for a road occupancy permit is extracted from the current state map data and the plan data and edited, and a road occupancy permit application (D19) and a number table attached thereto are created. I do. The written documents are submitted to the road manager (national or local government agency).
As a result of the road manager's check in step S11, each document related to the road occupation permission application is incomplete (NG)
, The application for changing the content of the application is made by the road manager, and the operation of step S10 is performed again.

If the application passes the road occupancy permission application check in step S11 (OK), the process proceeds to step S12.
At, the data required to apply for a road use permit is extracted from the current state data and design data and edited, and the road use permit application (D20) and the construction time (period) attached to this Create documents such as a list of effective road widths and traffic control maps. These documents are submitted to the road supervisor (the responsible police station), and again in step S
At 13 the road supervisor checks. Here, when each document relating to the road permission application is incomplete (NG), the road supervisor issues an "application content change instruction" and performs the operation of step S12 again.

In order to prepare such documents (application form and list, etc.) necessary for the application of the road occupation and the use permission, a format according to a format request from a road manager or a road supervisor of the submission destination is prepared in advance. The pattern is stored in the format pattern library, and graphic data representing guardman, barricade, construction vehicle, etc. is stored in the graphic library.
While reading out the format pattern in accordance with the type instruction of the document creation, necessary data is extracted from the sewerage floor plan drawing data obtained in the design stage. Then, by combining the extracted data with the read format pattern, an application form and a list can be created. In addition, the floor plan attached to the application (transportation plan, etc.) is also cut out from the plan floor plan, necessary figures are taken out from the figure library, combined with this drawing, and guardmen etc. are arranged freely. be able to. As for a specific method of preparing documents for such a road occupation permission application or a road use permission application, the present inventor has already proposed in Japanese Patent Application No. 2000-8675. I want to be.

When there is an "application change instruction" from the road manager or road supervisor in steps S11 and S13, if the designed sewerage floor plan itself has a defect, the process returns to step S5 and returns to step S5. ~ S11,
The processing of S5 to S13 is repeated. Then, step S1
After passing the road use permission application check in 3 (OK) and completing the submission of each application document, the construction stage (S14)
to go into.

[Construction-Completion-Management Stage: S14-17]
In step S14, a construction drawing including a plan view, a cross-sectional view, and the like reflecting the check results in steps S10 and S12 is created, and a sewer laying construction work is performed on site based on these construction drawings. This construction work is performed while changing the contents of the construction drawing data in accordance with the progress of the work process and the confirmation of the inconvenient location. When the construction work is completed and the inspection passes,
In step S15, based on the construction content change data obtained in the construction stage, a final construction drawing of the completed sewer is created. After completion, step S1
Enter 6, and prepare the sewer completion drawing into a sewer installation drawing suitable for management.

In step S17, this sewerage system diagram is linked to the GIS system and the drawing management system to construct a comprehensive sewerage management system, and performs the subsequent maintenance, inspection, and maintenance of the installed sewerage system. For example, by linking a sewage equipment database (CB5), which stores a large number of sewage equipment drawings as design results, with a drawing management system, drawings are managed for each construction subject, and life cycle support and information for various drawings and forms are provided. Achieve unified management of In addition, by linking with the GIS system, information search and management can be realized on a map basis, and can be used for various requests such as construction of other buried objects.
