  In the prior art, in order to check the interference of each process work and adjust the work time and work area (work area), it is necessary for all process work people to gather and make adjustments while consulting. However, it was a heavy burden on the person in charge of process work. Further, wasteful man-hours such as adjustment of work time at the work site, backtracking, waiting, etc. have occurred due to the fact that the adjustment results cannot be thoroughly communicated to the process work personnel in advance.

  First, taking a plant construction site as an example, a conventional method will be described for the process plan and interference between operations in each process, and subsequently, referring to FIGS. Embodiments of the system and work area interference detection system are described.

(Coordination of work at each process in plant construction)
The process plan is to adjust the order and period of a plurality of process operations of the target project so that all operations are completed within the contract period. Therefore, the process plan information includes information on all process operations. In many cases, the process plan is summarized mainly in a table format such as a bar chart. In addition, information on each process work (hereinafter referred to as process work information) includes work name (work item), work target product, work place, and period information, and the name of the person in charge or work team in charge of the work is added. In some cases.
Normally, the order and period of process work is adjusted so that each process work can be realized, and the process plan is made by calculating the period, but if the target project becomes larger and the period becomes longer, the main process Partial process plans, such as a table showing only work relationships and a table showing only process information focused on a certain place and period, are created according to applications.

In such a case, the person in charge of each position reflects the examination results in each process work information and makes changes, so the process plan is not consistent and the work location and work period interfere. May occur.
When interference occurs during actual work, adjustment of process work, waiting time of workers, and back-up work occur, which causes waste. Therefore, in addition to making pre-adjustments, which work is performed on the morning or the previous day. There may be a place where each person in charge carries out adjustments, such as where to take place. On the two-dimensional drawing, each person in charge writes the range of work to be performed that day, and if it is found that the work schedule or place interferes with each other, both sides discuss and make adjustments such that the changeable side shifts the schedule etc. ing.

  The interference in the work area of each process work when the process plan is formulated or when a process plan is changed or updated has been mainly adjusted manually as described above. In order to check whether there is any interfering process work or interfering work area, in addition to sufficient confirmation of each process work information, each person in charge will share a common two-dimensional drawing (for example, a drawing with a known layout) on the day before the work. I write and adjust the work schedule on the board (printed on the board or imitation paper, etc.), but the person in charge has to bother to write, and because it is handwritten information, it is only information as a picture In addition, it is not information that can be used as a result of the association of information or later, and the labor of editing the process plan and the work of coming to the writing and making adjustments were burdened by the workers.

  Concerning interference between operations, when adding operations, a method to check for interference at the beginning of the related operations or interference during the operation period, display the interfering operations, and search for alternatives to the work location is disclosed. (For example, refer to Patent Document 1). However, searching for a different location when the work area interferes is possible in large-scale work that can take time to prepare for each work, and work that cannot change the work place (for example, In the case of welding pipes to be placed at a specified location), the process must be adjusted in order to eliminate the interference.

  There are also means for digitizing work area information and automatically discriminating work area interference, etc., but the work area is entered by a worker one by one, and some areas However, application to an area where the work contents change every day takes a lot of time for input work.

  Furthermore, as explained above, the process plan is adjusted so that all process work is completed within the contract period of the target project, so that it is adjusted so that there is no interference or contradiction in the work area of each process work. It was assumed that. However, when a plurality of process operations are performed in parallel, as the number of process operations increases, problems such as inconsistencies in these process operations and interference in the work area become difficult to find.

  Therefore, the present invention aims to improve the accuracy of the process plan and the efficiency of the adjustment work by linking the process plan and the arrangement adjustment of the work area of each process work, and by linking both. In setting, the work area is automatically set according to the characteristics of each process work, and the work area where problems such as interference due to work area interference and restrictions (solvent use etc.) in each process work has occurred is clarified. It is an object of the present invention to provide a work area interference adjustment system capable of providing options for a solution and managing information on whether or not the problem has been solved.

And a temporary storage device. Necessary programs are installed in advance in the servers 2 and 3 and the terminal device 4.

(Operation outline of this system)
As described above, this system detects the interference of the work time of each work process and the interference of the work area, and supports the data input of the person in charge of each process work to eliminate this interference. In the following, first, an outline of the operation of the entire system will be described, and further, details of the operation will be described with reference to flowcharts (FIGS. 3 to 11, 16) and specific screen display examples (FIGS. 15, 17, and 18) and processes. This will be described with reference to data configuration examples (FIGS. 12 to 14) showing the contents of process related information including work information. The process related information is obtained by adding various data for detecting and displaying interference in the work area to the process work information.

  The calculation control device 11 of the work area display calculation device 1 defines in advance the devices (process plan information storage server 2, three-dimensional layout information storage server 3, terminal device 4) related to the work area display calculation device 1. Various programs corresponding to various data reading and calculation from the reading of the process work information to the generation / display of the 3D layout or the 2D layout are read out and executed.

In the terminal device 4, a person in charge of each process work displays a two-dimensional layout or a three-dimensional layout of the work area, confirms interference with other work, and consults with another person in charge if necessary. Perform processing to eliminate interference.
For this reason, the arithmetic and control unit 41 of the terminal device 4 can change each process work (implementation time, period, place) or a new one to eliminate work interference and work area interference as described above. An input support program for adding process work is executed. Moreover, the input change information of the process work is transmitted to the work area display calculation device 1, and the work area display calculation device 1 stores the change information by associating or adding to existing data.

  For example, when a person in charge of each process work changes a work area or inputs a new process work work area in the terminal device 4, the building work place is first entered and the building stored in the server 3. The drawing data and installed equipment data are read out and displayed on the display. This display is initially performed in a two-dimensional layout, and a work area is input on this display. This input operation is performed using graphic input or numerical input as appropriate, and input is performed using a GUI for this input. Further, at this time, if there is an interference (time or work area) in other process work, this is simultaneously displayed. A display example of the input work area will be described later.

  The 3D layout information stored in the 3D layout information storage server 3 includes, for example, CAD design data (drawing data) of an area where work is performed in plant construction. Furthermore, data regarding the shapes and installation locations (coordinates) of the equipment and various products installed in the installation work inside and outside the building are also included in this three-dimensional layout information.

  In addition, as described below, in the embodiment of the present invention, the generation of the three-dimensional layout data for displaying the work area is also performed based on the building drawing data according to the instruction from the work area display calculation device 1, The generated three-dimensional layout data is transmitted to the work area display calculation device 1.

It should be noted that the above three-dimensional layout data can be generated not on the server 3 but on the work area display computing device 1 side.
Further, the functions of the process plan information storage server 2 and the three-dimensional layout information storage server 3 can be incorporated in the work area display calculation device 1 and can be configured entirely by one computer.

The two-dimensional layout data is stored in the work area display arithmetic unit, but may be stored in a storage device of another computer on the network.
Here, the process plan information storage server 2 and the 3D layout information storage server 3 are different computers on the network, and the 2D layout data is stored in the work area display device 1. .

  The program installed in the terminal device 4 may be a program having the same function as the program installed in the work area display computing device 1, but only a part of the functions are operated. May be. This is because, for example, if the process work information can be changed in all the terminal devices 4 in order to eliminate interference in the work area, there is a possibility of causing confusion. Functions that are not required for each terminal device may be disabled.

(Detailed explanation of the operation of this system)
FIG. 3 is an overall flowchart of data processing for displaying a work area in the work area interference adjustment system according to the present invention. 4 to 11 are flowcharts for explaining the process in each step of the flowchart shown in FIG. 3 in more detail, and respectively correspond to the processes in steps S100 to S800 of the flowchart in FIG.
Hereinafter, a work area display method in the work area interference adjustment system according to the present invention will be described with reference to FIGS.

  Although various forms are possible for the work area display form, two forms will be described here. First, an embodiment in which daily work area display is performed in order to confirm daily work in plant construction work will be described, and then work area display information will be displayed during process plan formulation / adjustment in order to refine the process plan. The form (modification) which produces | generates and displays is demonstrated.

  In step S100, processing for extracting data necessary for displaying the work area as a three-dimensional / 2-dimensional layout is performed based on the process work information. In step S200, three-dimensional layout data and two-dimensional layout data of the work area are generated based on the data extracted in step S100. In step S300, two-dimensional layout data in which a work area is additionally displayed is generated based on the two-dimensional layout data generated in step S200. As described above, data for displaying the work area in each of the three-dimensional layout and the two-dimensional layout is prepared, and these data are used for confirming the interference of the work area in the next step.

In step S400, it is confirmed whether there is work area interference. In some cases, there is no interference in the work area in the three-dimensional layout, but it may appear to interfere in the two-dimensional layout.
In such a case, it is conceivable that two different process operations are performed at different heights above and below the floor of the same building, for example, with a scaffold. Alternatively, in a large product or facility, an intermediate floor for work / operation may be provided in the floor. In such a case, two process operations may be possible at the same time, but depending on the work contents, it may not be allowed to perform them simultaneously for safety measures.

  Therefore, when the work area interferes and when it apparently interferes with the two-dimensional layout, the presence / absence of interference in the process work information of each process work and the interference or apparent interference. Information about the other process operation is added. The person in charge of each process work may only display the process work information data (work contents, work time, work area, etc.) of the process work that he / she is in charge of. This is because it is necessary to provide information on the other process operation.

  The processing in the above steps is automatically executed every day by the work area display calculation device 1, but the processing in and after step S500 involves the person in charge of each process work.

  In step S500, the work area is displayed in a three-dimensional layout or a two-dimensional layout, and the person in charge of each process confirms the presence or absence of interference with other process work. In step S600, when it is confirmed that there is interference, the person in charge of the process work adjusts process work information such as work time and work area in order to eliminate this interference. In step S700, the work area reflecting the change made by the person in charge of the process is disclosed (displayed) so that the workers involved can confirm the 3D layout or 2D layout of the work area. In step S800, the worker confirms the published work area information. In this step S800, the worker confirms the work area and the work schedule of the process work that the worker is in charge of for safety and when the work is changed.

  Hereinafter, operations of interference detection and interference adjustment according to the present invention will be described in detail for each of steps S100 to S800 in FIG.

(Process information acquisition / definition information association step)
FIG. 4 is a detailed flow of the process in step 100 of FIG.
In the work area display arithmetic device of this system, the program is started at a time determined every day based on the clock held by the arithmetic control device (CPU) 11 (step S101).
In step S <b> 102, the arithmetic and control unit 11 reads from the storage device 12 information on a period for performing interference detection and a region (area) to be subjected to interference detection set in advance by the person in charge of adjusting the entire process work. The period and area data are stored in the storage device 12, but are stored in the storage device C123, for example.

  If the period for performing interference detection and the area to be subjected to interference detection are not set, for example, the process work information of the process work scheduled for work on the next day and the entire area including the work area of this process work The building drawing data and the data on the outline and installation location of the equipment already installed in the entire area are targeted. The whole area including the work area of one process work is, for example, the entire floor of the building where the work area of this process work is, and is 3D drawing data of the floor. The example described below in this embodiment is also a case where the period and region are not set in this way.

  Next, in step S <b> 103, the arithmetic and control unit 11 issues an acquisition instruction to the communication device 15 so as to acquire necessary information from the process plan information stored in the process plan information storage server 2. The instruction information includes the computer in which the process plan information is managed, that is, the information of the process plan information storage server 2, the designation of information (process work information) to be read from the process plan information, the target period (days), the target work area (Building, floor) information is included. The information communication device 15 transmits the acquisition instruction information to the designated computer in accordance with the acquisition instruction. When the process plan information storage server 2 receives the acquisition instruction information (step S1031), the process work information included in the process plan information is read from the storage device 22 (step S1032), and transmitted to the work area display calculation device 1 (step S1033). ).

  As shown in FIG. 12, the process plan information (data) is stored in the storage device 22 of the process information storage server 2 with contents and configurations such as a process plan list L1, an individual work schedule list L2, and a work team configuration list L3. ing. The contents of the process work information of each process work are: work item K01, work number K02, work target product name K03, product number K04, work start time (date or date + time) K07 / K09, work end time (date or Date + time) K08 / K10, information about work place K05, information about work team K06 and worker K10.

In the example shown in the present embodiment, the data of the work group configuration list L3 having information on the process plan information storage server 2 side and including the number of workers K11 associated with the process plan information is used as process work information. It is assumed that it is transmitted to the device 1. The work group configuration list L3 is associated through a “work group” K6 or the like.
The work group configuration list L3 may be stored in the storage device 12 of the work area display calculation device 1 instead of the process plan information storage server 2. In that case, the work group configuration list L3 is associated with the process work information transmitted to the work area display computing device 1.

  In step S <b> 104, when the communication device 15 receives the process plan information (data) from the process plan information storage server 2, the communication device 15 temporarily stores the process plan data and the received information in the temporary storage device 115.

In step S <b> 105, when the operation control device 11 confirms that the process plan data has been received with the reception information stored in the temporary storage device 115, first, the operation control device 11 numbers each work process. At this time, a non-public flag is set in the public flag field. This number (hereinafter referred to as the system number) is used as a keyword for associating information transmitted / received between the work area display computing device 1, the three-dimensional layout information storage server 3, and the terminal device 4.
In step S106, the information (data) of each numbered process work is stored in the storage device C123 as a process related information list L4 (see FIG. 13). When the storage of the process related information list L4 in the storage device C123 is completed, the process plan information stored in the temporary storage device 115 may be deleted.

  FIG. 13 shows an example of a process related information list L4 created by associating various contents of each process work. In the example of FIG. 13, the information is arranged side by side, but as long as the association is possible, the storage form is not limited, for example, the information is stored in a plurality of storage areas. Further, the content displayed in FIG. 12 is included in or associated with the process related information list L4 shown in FIG. Incidentally, the contents of the work group configuration list L3 shown in FIG. 12 are not included in the list of FIG. 13, but as shown in FIG. 12, they are also associated with the data of the work group in the process related information list L4 as shown in FIG. And stored in the storage device C123.

  In step S107, the arithmetic and control unit 11 loads and executes the association definition program from the storage device A121, associates the work area information of the storage device B122 related to the process work information stored in the storage device C123, and associates the association program. The work area information of the storage device B122 is added to the process work information of the storage device C123 (see FIG. 14). The information related to the work content of the process work information includes a keyword for associating with the work area information. This keyword may be the work item name of the work content K01 in the process plan list L1, the number of each process work (No. in the process plan list L1 in FIG. 12), the work number of the work content K02, or the like. However, in the example shown in FIG. 13, the number (No.) of each process operation is used.

  The work area information is various pieces of information about all work contents that may be associated with the process work information in advance. For example, work area data for each work item (such as work area shape information in FIG. 13) is stored in the storage device B122. Data for drawing graphics) and information regarding work restrictions. This content includes words or numbers that are keywords associated with the process work information. Information can be associated with this keyword, and appropriate information can be added to each process work information from the defined information.

  The storage device C123 is provided with a frame for writing various definition information related to each piece of process work information, and the information input by the person in charge of each process work is written in the frame, and the process related information shown in FIG. Assume that a list L4 is generated. Here, the process related information list L4 is described as being stored in the storage device C123, but the storage region is not particularly limited as long as it is an area of the storage device 12.

  When the addition of necessary information from the definition information is completed in step S108, the arithmetic processing unit 11 next corrects the work area. The work area is corrected based on a correction constant for the number of workers described in the work area correction definition information.

  The work area correction definition information is configured as a work area correction definition information list L5 as shown in FIG. 14, for example. The work area correction definition information list L5 exceeds the system number as a keyword for associating information with the process related information list L4, the shape information for each system number, the number of standard workers, and the number of standard workers. In this case, a constant (correction constant) for obtaining a correction coefficient is used. In addition, you may make it include the definition of the calculation formula for calculating | requiring a correction coefficient. Since the work area per person may be larger than the standard depending on the work, this correction constant corresponds to the correction coefficient for the work area per person of this standard. Here, the standard work area is the minimum work area per person. For a work that requires a standard work area and does not require correction, the correction constant is set to 1 in this example.

  The arithmetic processing unit 11 reads the correction program from the storage device A121 (step S1081). The correction definition information stored in the storage device B122 is also read out and stored in the temporary storage device 115 in the arithmetic processing device 11 (step S1082). The correction coefficient for the work area shall be obtained by applying correction constants to the number of workers exceeding the standard number of workers.

For example, in the work group configuration list L3 in FIG. 12, the number of the BB team in charge of work number 1 is five, but in the work area correction definition information in FIG. Suppose it was a name. In this case, the correction coefficient F is F = 1 (corresponding to the size of the original work area)
+2 (additional number of people) x (0.5 (correction constant per additional number of people))
= 2
It becomes.
This correction coefficient F (= 2.0) is used as the work area shape information X (= 5000), Y () of the work area information of the process work of the number (No.) 1 in the process related information list L4 of FIG. = 5000), and X (= 10000) and Y (= 10000) of the work area shape information of the corrected work area information are calculated.

In steps S1083 to S1086, the work area described above is corrected.
First, in step S1083, the arithmetic processing unit 11 compares the number of workers in each record with the standard number of workers defined for each work number included in the correction definition information. If the number of workers assigned to the work read from the process plan information is larger than the number of standard workers (the number of workers described in the work team configuration list L3 in FIG. 12), the process proceeds to step S1084, and the number is large. A work area correction coefficient corresponding to the number of people is calculated. . The calculated work area correction coefficient is multiplied by information indicating the work area of the target record and the work area correction coefficient, and the information indicating the work area shape is corrected (step S1085).

Depending on the type of work, if the number of workers increases, measures such as widening the work range may be required, but measures can be easily taken through the above-described steps.
In step S1083, if the number of workers is below the standard, the work area is not corrected and the process returns to step S108.

  In step S109, the corrected result is added to the process related information list in the storage device C123, and the correction of the work area is completed.

  In the present embodiment, for work that does not require correction, the correction constant is set to 0, and as a result, correction is not performed. However, correction is necessary before the correction is performed in step S108, including the necessity of correction included in the definition information. Steps S1081 to S1086 may be performed only on items that need correction by looking at the rejection information. At this time, for the items that do not require correction, step S108 is not performed, and the process of step S100 is completed.

(3D layout / 2D layout data generation step)
Next, a step of generating a 3D layout / 2D layout from the process related information list L4 in which the above process plan information and the above definition information are associated will be described.
First, in step S200, 3D layout layout / 2D layout data is generated, and using the acquired coordinate information, a 2D layout including a work area is output in step S300. The three-dimensional layout is displayed in step S500.

  In the generation of the two-dimensional layout information of the process related information list L4, two processes are performed. One is to look at the 3D layout from the top to make it 2D layout information and to display the coordinate information on the 2D layout data of the raster data or the 2D layout created to display the work area. Append. Furthermore, graphic information (work area shape information) indicating this work area is added to the process related information list L4. A predetermined file name is given to the two-dimensional layout data.

  Hereinafter, a display example of a work area using a two-dimensional layout will be described. In addition, when it is necessary to secure work areas across floors, it may be desirable to use a picture of 3D layout information viewed from the top, so in some cases only 3D layout information can be used or combined It has become.

The three-dimensional layout output (step S200) will be described with reference to FIG.
First, in step S201, the arithmetic control device 11 of the work area display arithmetic device 1 loads and starts a program for displaying a three-dimensional layout from the storage device A121. The arithmetic and control unit 1 firstly stores the process related information list L4 stored in the storage device C123 and the three-dimensional layout data related to each work in the process related information list L4, that is, the building drawing data ( A command for generating 3D layout data of an area (building floor) in which work is performed from CAD design data), 3D layout data of a product to be processed, and 3D layout shape of a work area of the process work Is transmitted to the three-dimensional layout information storage server 3 via the communication device 15. At this time, the process-related information list L4 does not include product coordinate data.

  In step S202, when the communication device 35 of the three-dimensional layout information storage server 3 receives the instruction signal, the communication device 35 stores the process related information list L4 (see FIG. 13) included in the transmitted signal of the calculation control device of the server 3. The data is stored in a primary storage device (not shown). Next, in step S203, the arithmetic and control unit 31 of the three-dimensional layout information storage server 3 reads the product name from the process related information list L4 stored in the primary storage device, and obtains the three-dimensional layout information (CAD data) of the corresponding product. Identify.

  In step S204, the coordinates (three-dimensional coordinates) of the three-dimensional layout information (CAD data) of the corresponding product are read from the storage device 32 and added in association with the process related information list L4 of the primary storage device (step S204).

  In step S205, the arithmetic and control unit 31 reads out the three-dimensional layout information (CAD data) and the three-dimensional layout data (CAD data) of the corresponding product.

  In step S206, from the shape information of the corrected work area read out from the process related information list L4 and its reference point, the coordinate position is matched with the three-dimensional layout data of the work place, and the three-dimensional layout of the corresponding product is obtained. 3D layout data including drawing, corresponding product, and work floor is generated. Further, two-dimensional layout data obtained by projecting the generated three-dimensional layout onto a plane is also generated.

  In step S207, the process related information list L4 (same information output to the three-dimensional layout information storage server 3) including the coordinate data added in step S204 and the two-dimensional layout data file name added in step 206, and step The two-dimensional layout data file generated in 206 is transmitted to the work area display computing device 1 via the communication device 25. The process related information list L4 is stored in the storage device 32. Since the process related information list L4 stored in the storage device 32 of the three-dimensional layout information storage server 3 is positioned as a copy of the process related information list L4 of the work area display calculation device 1, the work area display calculation device 1 uses this process related information list L4. When the information list L4 is changed, the change information is transmitted to the three-dimensional layout information storage server 3 each time.

  In step S208, when the communication device 15 of the work area display calculation device 1 receives the information (process related information list L4 and the two-dimensional layout data file) from the three-dimensional layout information storage server 3, the received information is calculated by the calculation processing device. 11 to send. The arithmetic processing unit 11 stores the received information in the storage device C123.

  Thus, the three-dimensional layout information storage server 3 completes the generation of the three-dimensional layout data, the acquisition of the coordinate information of the corresponding product from the server 3, and the acquisition of the two-dimensional layout data.

  Note that the 3D layout information storage server 3 for storing the 3D layout information is not particularly provided, and for example, a configuration in which the 3D layout information is stored in the work area display computing device 1 is also possible. In this case, since both the two-dimensional layout information and the three-dimensional layout information are stored in the same computer, step S207 and step S208 may be omitted, and writing to the two-dimensional layout information may be continued. Therefore, step S207 and step S208 can be omitted.

(How to set / display the work area)
As described in step S100, the shape information of the work area is set from the beginning in the process related information list L4. Although detailed description is omitted, it is preferable to prepare a work (tool) or the like for setting the shape information of the work area and prepare the work area shape information in advance. For example, the shape data (CAD data) of the corresponding product of the process work is read from the three-dimensional layout information storage server 3, and the work area shape (cylinder, rectangular parallelepiped, size, reference point, etc.) is set so as to match it. A mechanism for adding information to the related information list L4 may be incorporated. For example, in the present invention, a basic process plan list L1 (FIG. 12) is first created, and an input interface (GUI) that can create the other lists L2 to L7 described above is incorporated using this list L1. Just go. For example, in FIG. 12, when the column of work location information K05 is selected, a work area setting screen appears. On this setting screen, necessary building drawing data is displayed, and an area necessary for this display is indicated, or this necessary information is displayed. Select a figure (cylinder, cuboid, etc.) corresponding to the correct area so that the work area is defined. Thus, the work area shape information defined on the screen may be written as the work area shape information in the process related information list L4. A similar mechanism may be provided for the generation and modification of the other lists L2 to L7.

  Depending on the type of work, the work may occur where the product is not finally installed. For example, in the work of carrying in products, for example, large-sized equipment is carried in, and there is no floor on the upper floor, and the upper floor is opened as the upper space of the lower floor, and is carried in from the upper floor, When moving and installing on a lower floor with a crane or the like, it is desirable that the work area has a space for carrying in all the upper part of the installation work place (for example, a room). In such a case, it is only necessary to secure the necessary work area by displaying the building drawing data of a plurality of related floors by displaying the building drawing data as described above.

  Note that information included in the process related information list L4 that is not information for displaying the shape, such as the system number No. and work date information, is also associated with the information so that it is described on the 3D layout information storage server 3 side. Is stored as a part of the three-dimensional layout information.

  As a standard work area display figure, a simple figure such as a rectangular parallelepiped or a cylinder is prepared, but other complicated shapes may be used. In this case, information indicating the shape and parameters thereof are stored in correction definition information (see FIG. 14 described later) stored in the storage device B122 of the work area display arithmetic device 1.

  Basically, a product having a three-dimensional layout is arranged at the center of a shape indicating a work area. In the case of a product in which the reference point of the three-dimensional layout product is at the end point, the product is automatically calculated and corrected so that the midpoint of the product is the center of the shape indicating the work area.

  Depending on the work, the work area may be biased rather than the center of the product. For example, the work area should be arranged on the front door side of the distribution board for cable connection. In such a case, information can be defined in advance so that a shape indicating the work area is arranged at a position deviated from the center of the product. As a result, three-dimensional layout data to which a work area is added is generated.

(Drawing the work area on the 2D layout)
With reference to FIG. 6, step S300 for rendering the work area in the two-dimensional layout will be described.
In the present embodiment, it is assumed that the two-dimensional layout information includes two-dimensional layout data and coordinate information. The two-dimensional layout information is stored in the storage device D124 of the work area display calculation device 1 (step S208). Like the three-dimensional layout information, the two-dimensional layout information may be in another computer connected via a communication device.

  In the present embodiment, the two-dimensional layout information includes a two-dimensional layout created for each floor of each building. For example, if there are three buildings in the project to be applied and each has five floors, the two-dimensional layout information is 15 drawings corresponding to 15 floors. Such a configuration of the two-dimensional layout information may create a two-dimensional layout in various division units as appropriate so as to be easy for the operator. However, since the confirmation is made in two dimensions, if the floors cross over, they are color-coded for each floor, or two two-dimensional layouts are displayed vertically or horizontally as necessary. .

When the storage of the three-dimensional coordinates is completed in step S208 as described above, in step S301, the arithmetic and control unit 11 reads and activates a program for drawing a work area in a two-dimensional layout from the storage device A121.
The two-dimensional layout is original data for rendering information on different process operations every day. In order to write the work area of the day, the original data before rendering the work area is copied to the storage device D124 with a specific name. The specific name may be a rule in which a rule is determined in advance, and it may be created manually or by creating a program and automatically creating a copy every day at a certain time. The name can be any number format as long as it is necessary to know the schedule and floor.

  The calculation control device 11 of the work area display calculation device 1 reads the process related information list L4 of the storage device C123, and then reads the coordinates of each building stored in the storage device B122 (step S302). Based on the product coordinate information of the list L4 and the coordinates of each building, the type, hierarchy, and two-dimensional layout number of the building are specified. The identified information is stored in the storage device C123 in association with each piece of information in the process related information list L4 (step S303). This makes it possible to classify which data is drawn in which two-dimensional layout.

In the present embodiment, the building can be specified from the coordinates of the two-dimensional layout information. In some cases, the two-dimensional layout information itself, such as by building, by floor, or by area, may be divided into several data blocks as appropriate. In that case, since the data of each data block of the two-dimensional layout information may have a reference point of different coordinates, the building information and the information of each floor are not coordinates, but from the DB or file name, etc. May get. If the 2D layout data is further divided on one floor, information for division is created in advance based on the coordinate information, and the 2D layout data is classified for each work floor. It becomes.
In this way, the two-dimensional layout data and work areas are classified for all process work (step S304).

Next, the work area is written in the two-dimensional layout. Since all the divided and classified two-dimensional layouts are prepared at this time, the order is determined in advance, and the work area is written according to the order.
First, the number of the first two-dimensional drawing is called (step S305). Next, from the process related information list L4 stored in the storage device C123, the data of the two-dimensional layout data file name selected based on the two-dimensional layout data file name specified and associated in the previous step S303 is stored in the storage device. The data is read from D124 and stored in the primary storage device (step S306).

  Since the two-dimensional layout data has coordinates, first, the reference coordinates obtained from the three-dimensional layout information are specified by the two-dimensional layout data, and the corrected work area shape (steps S108, S1081 to 1086) is centered on the reference coordinates. Only the coordinates used in two dimensions are read out from the coordinates representing the reference) to create a work area shape. Further, the work content display data (see FIG. 13) stored as one of the work area information is read, the color of this work area shape is changed, and the corresponding restriction display mark is stored in the storage device B122 from the work area restriction information. Are arranged at the reference point of the work area (step S307).

  If all work area shapes have been drawn, proceed to the next step. If the drawing of all the work areas is not completed, the process continues until the shapes of all the target data are drawn (step S308). When all the work area shapes have been drawn, steps S305 to S308 are performed on the next two-dimensional layout data, and this is performed on all the two-dimensional layout data (step S309). As a result, two-dimensional layout data describing the work area, the work content, and the restriction information is created.

  The two-dimensional shape rendering of all the work areas described above is usually performed by repeatedly performing the processes in steps S306 to S308 when the user or the like views the information on these work areas. That is, when steps S306 to S308 are executed once, the shape of one work area, the work contents corresponding to this work area, and the restriction information are displayed. If the display takes a very long time, an image in which the two-dimensional layouts of all the work areas are drawn may be stored and read and displayed when necessary.

  Although description is omitted above, for example, when the outer shape of a product to be installed is complicated, the corresponding work area shape is displayed so as not to be a complicated shape. In such a case, a three-dimensional shape of the product is generated in advance from information such as the product, and a figure such as a cylinder or a rectangular parallelepiped that can include the three-dimensional shape is displayed as a work area. I will do it.

  Information on the work area for such a complex shaped product may be separately calculated and input in advance. Further, a mechanism (GUI) may be incorporated in which data of a three-dimensional shape of a product is input and the shape is displayed, and a figure in a work area that can include the three-dimensional shape can be selected.

(Judgment of work area interference, judgment of presence / absence of vertical work)
Next, a method for determining whether there is no problem with interference in the work area will be described with reference to FIG.
In the work area interference detection and interference adjustment system according to the present invention, it is determined whether or not the work areas interfere with each other and whether or not the work areas overlap each other in the same floor (hereinafter referred to as up and down work). The problem with up and down work is that, for example, when an object is dropped in the upper work, there is a possibility that the worker working in the lower work may hit the fallen object. Alarm display (restriction mark display to be described later) or the like is performed for safety reasons. The person in charge of the work or the person in charge of the work confirms the interference state of the work area and takes measures such as avoiding work having a safety problem or changing the schedule of the work process so as not to interfere. In addition, when work that interferes or work that overlaps vertically is unavoidable, the work can be performed while sufficiently confirming safety by referring to the interference result according to the present invention.
In the following description, a plurality of process operations that do not interfere with the operation time are excluded from targets for which interference is detected because the operation area does not interfere with the actual operation.

  First, in step S401, the arithmetic control device 11 of the work area display arithmetic device 1 reads the problem confirmation program from the storage device A121 and starts it. In step S402, work floors are selected in the order preset in the program. Information on the process work related to the selected work floor is read from the process related information list L4 stored in the storage device C123 and stored in the temporary storage device 115 (step S403).

  Subsequently, the information read from the process related information list L4 is used to check whether the work teams of the two works are the same in a predetermined order. For example, the system code No. One task is selected according to the order of small (step S404), and this work group is compared with another work group (step S405). If the work group is different, the process proceeds to step S406. If it is the same work group, the process proceeds to step S410.

If the work to be compared is performed by the same team, it is considered that the work is performed by adjusting the work time in the same team, so there is no need to consider interference in the work area.
However, if the working time interferes (overlaps), there is a possibility that the process work information and the process plan information data have an error. A flag, for example, a comment flag shown in FIG. 14 is set. In the following, for simplification, the interference of the work time of the same work team is omitted.

When the two tasks are work of different work teams, the shape of the work area projected on the two-dimensional layout is calculated from the parameter indicating the corrected work area shape, and the two-dimensional work area is calculated from the coordinate values of the two-dimensional work area. Interference with other work areas in the layout is calculated (step S406).
If there is no interference on the two-dimensional layout, there is no interference in the work area, and the process proceeds to step S410. If there is interference on the two-dimensional layout, the process proceeds to step S407.

  In step S407, it is determined whether the work area is three-dimensionally interfering. As the work area, a three-dimensional work area (a cylinder, a rectangular parallelepiped, or the like) may be set at a predetermined height from the floor surface. Accordingly, it is determined whether the work areas interfere with each other, including the height position of the shape of the work area.

  If the work area interferes on the plane and also interferes in three dimensions, it is determined in step S408 that the work area interferes, and the process related information list L4 and the interference work list L7 (see FIG. 13). ). A flag indicating whether or not there is an interference operation (hereinafter referred to as an interference operation flag) is set in the process related information list (see FIG. 13), and what is actually interfering with the interference operation list L7. sign up.

  It is assumed that the interference work list L7 includes key information that can be associated with the process related information list L4. In FIG. 13, the system number is used as an association key. In addition, when a plurality of other work areas interfere with one work area, a mechanism is adopted in which all interfering work areas can be registered.

  If there is interference on the two-dimensional layout but not on the three-dimensional layout, it is written in the process related information list L4 and the up / down work list L6 (see FIG. 14) in step S409.

  A flag indicating whether or not there is an up / down operation is set in the process related information list L4 (hereinafter, referred to as an up / down operation flag), and what is an up / down operation is registered in the up / down operation list L6. As in the case of the interference work list L7, it is assumed that the upper and lower work lists L6 also include information serving as keys that can be associated with the process related information list L4. In addition, when a plurality of other work areas are in a vertical relationship with respect to one work area, all the work areas in the vertical relationship can be registered. When the interference work flag or the up / down work flag is set in the process related information list L4 in steps S408 and S409, if the flag has already been set in the previous comparison, it is left as it is, and the process goes to the interference work list L7 or the up / down work list L6. Only additional registration of

  Next, in step S410, it is determined whether the shape has been compared with the work areas of all work other than the selected work existing on the same floor. If the comparison with all work area shapes has not been completed, the process returns to step S404, the next work is selected, and the shape comparison with work areas other than the selected work (steps S403 to S410) is repeated. These steps S403 to S410 are performed for all floors (step S411).

When the comparison of the above work areas is completed for all the floors, the process proceeds to step S412 and the arithmetic processing unit 11 of the work area display arithmetic unit 1 causes the communication unit 15 to interfere with all the work areas in the process related information list L4. Flag, up / down work flag and system code No. Is sent to the 3D layout information storage server 3 to transmit the updated process related information. Upon receiving these pieces of information, the server 3 stores the process related information updated by the work area display calculation device 1 in the storage device 32 in step S413.
The determination process for the presence / absence of interference work and vertical work is thus completed.

(Interference work area and upper and lower work area display)
The 3D layout and 2D layout are generated and output based on the information stored in the storage device when the person in charge or the operator views on the monitor screen (output device 44) of the terminal device 4 or the like. As with the restriction information, the interference work flag and the up / down work flag are also displayed on the device 44. If these flags are present, the product coordinate value is associated with the flag and has a shape or mark set in advance. Shall be displayed.

  FIG. 15 shows an example of a screen image of a three-dimensional layout and a two-dimensional layout to which a plurality of work area shapes and marks indicating that these work areas interfere with each other or have a vertical relationship are added.

(Correction steps by workers)
Next, the person in charge confirms the information (data) extracted from the process work information as described above, and if necessary, corrects the extracted data as shown in FIG. The description will be given with reference. Here, the person in charge is different for each building and product. Of the workers in each work, the person in charge of confirming the data extracted from the process work information is described as a person in charge, and the person in charge of each work including the person in charge is described as a worker.
In addition, the process of the double line frame in the process in the terminal device 4 in the drawing indicates that the process includes an input operation by the person in charge.

  When the calculation control device 11 of the work area display calculation device 1 generates a two-dimensional layout including all the work areas extracted from the process related information list L4, it is extracted from the program of the next step, that is, the process work information from the storage device A121. A program for correcting the read data is read and started (step S501). Next, the person-in-charge list is read from the storage device D125 (step S502), and the arithmetic and control unit 11 sends a warning message indicating that there is a problem (interference work, up / down work) or a mail delivery instruction or identification. The communication device 15 is instructed to transmit the person in charge through the notification instruction to the terminal device or the communication system or both (step S503). It is assumed that the mail content and the notification instruction content to the communication system are included in the instruction from the arithmetic and control unit 11.

  The warning message may be transmitted to each person in charge on the terminal device 4 side of the system from the arithmetic control device 11 or distributed to the terminal device 4 side of the system upon receiving an instruction from the work area display arithmetic device 1. Contact details may be prepared in advance. The notification contents include, for example, the completion of 3D layout and 2D layout generation including the work area for each work on the next day, and a request for confirmation of the work area for each work.

  Upon receiving an instruction to send a warning message from the arithmetic and control unit 11, the communication device 15 performs mail delivery to the person in charge and / or instructions to contact the person in charge in the communication system (step S504). The contact system may be a PC used by each person, various mobile terminals, and any receiving means.

  When the person in charge receives information from the communication device 15 at the terminal device 4, the PC used by each person, the mobile terminal, or the like (step S505), a system for confirming the work area at the terminal device 4 (hereinafter, work area confirmation correction) (Described as “system”) is started (step S506). When this work area confirmation correction system is activated, the name of the person in charge is input. It should be noted that a password for each worker may be prepared and entered by the person in charge (for example, described later) so that only the authorized worker can activate such a work area confirmation correction system. It is displayed as shown on the left side of FIG. When the work area confirmation / correction system is activated, this information is transmitted to the work area display calculation device 1 to recognize who is working on which terminal device.

  When the work area confirmation correction system is activated, the person in charge selects which two-dimensional layout to view. The work area confirmation correction system displays a screen for selecting a two-dimensional layout name or a building floor name from the output device 44 of the terminal device 4. The information selected by the person in charge is input from the input device 43 of the terminal device 4 and sent to the arithmetic and control unit 41 (step S507). The work area confirmation correction system transmits information on the selected two-dimensional layout to the work area display calculation device 1 via the communication device 45 of the terminal device 4.

  When receiving the signal from the communication device 15, the work area display calculation device 1 transmits information on the corresponding two-dimensional layout to the terminal device 4. At this time, if the work area of the work having the interference work and the up / down work is included in the information of the two-dimensional layout transmitted from the terminal device 4 to the work area display calculation device 1, the interference work and the up / down Information on the two-dimensional layout of the work is also transmitted to the terminal device 4. Even when the two-dimensional layout of the interference work and the vertical work is not selected in step S507, information on these works is transmitted to the terminal device 4.

  When receiving the signal from the work area display computing device 1 (step S508), the communication device 45 of the terminal device 4 transmits a reception notification signal notifying that this signal has been received to the computation control device 41 (step S509).

  When receiving the reception notification signal from the communication device 45, the arithmetic and control device 41 stores the information received by the communication device 45 in the primary storage device 411. Further, the arithmetic and control unit 41 reads the two-dimensional layout information selected in step S507 from the primary storage device 411, and transmits the selected two-dimensional layout information to the output device 44. The output device 44 displays the two-dimensional layout in which the work area is drawn and the work content. When there is interference work and up / down work, as shown in FIG. 15A, a mark indicating that there is a problem to call attention to the worker is displayed in a state of being superimposed on the two-dimensional layout ( Alarm display) (step S510).

  When the person in charge displays the 2D layout and the work content, the work content and work location (that is, the position of the work area) are correct, whether the work area is sufficient, and the work area interferes with other work. It is confirmed whether it is not (step S511).

  If it is difficult to confirm with the two-dimensional layout, or if it is desired to confirm more detailed work area peripheral information, it is determined in step S512 that confirmation of the three-dimensional layout is necessary, and the process proceeds to step S513. View and confirm the layout. If it is not necessary to confirm the detailed work area, the process proceeds to step S523.

  For example, the person in charge selects what he / she wants to confirm the three-dimensional layout from the list on the right side of FIG. 15A and presses the “three-dimensional layout button” on the upper right. Alternatively, each work area displayed in FIG. 15A may be selected with a mouse. Note that the work names displayed in the list on the right side of FIG. 15A correspond to the work areas displayed on the screen.

Although not shown in FIG. 15, a work area shape selected to display the three-dimensional layout may be highlighted (temporarily changed to another color). .
In addition, the name of the person in charge who started the work area check correction system may be added to the process related information list L4 as a checker.

  In step S514, the calculation control device 41 of the terminal device 4 stores the selected work name or number input from the input device 43 in step S513 in the temporary storage device 411, and also stores the three-dimensional layout information in the communication device 45. Send a signal instructing the acquisition of. This information includes information for identifying the work, such as the work name and the system number assigned to each work. When receiving the signal, the communication device 45 of the terminal device 4 transmits the signal to the three-dimensional layout information storage server 3 based on the instruction information.

  Next, when the communication device 35 of the three-dimensional layout information storage server 3 receives the signal in step S515, it delivers the content of the received signal to the arithmetic control device 31 of the server 3. The arithmetic and control unit 31 stores the content of the received signal in a primary storage device (not shown). The received signal includes information on the terminal device 4 that has transmitted, that is, information on which terminal device. Subsequently, in step S516, the arithmetic and control unit 31 specifies shape information having the corresponding system number from the three-dimensional layout information.

  In step S517, the arithmetic and control unit 31 specifies the product name or number arranged in a predetermined space centered on the specified work from the above three-dimensional layout information. At this time, a shape indicating a work area other than the same day as the specified work arranged in the predetermined space is excluded. Note that 3D layout information other than the work area shape is not excluded. From the specified product name or number and the process-related information list L4 stored in the temporary storage device (not shown) of the server 3, all information relating to the specified product name or number is stored in the primary storage device. This includes all information for reproducing the three-dimensional shape of the work area.

  Next, in step S518, the arithmetic and control unit 31 stores the work area information stored in the primary storage device (not shown) and the information for reproducing the three-dimensional shape, and the primary storage device when receiving the signal. The communication device 35 of the server 3 is instructed to transmit the information of the terminal device 4 that is the transmission source to the terminal device 4 that has transmitted the information. Upon receiving the instruction, the communication device 35 transmits information stored in a temporary storage device (not shown) to the terminal device 4.

  When the terminal device 4 receives the work area related to the work selected in step S513 and the three-dimensional layout information from the communication device 35 of the three-dimensional layout information storage server 3 in step S519, the terminal device 4 stores these pieces of information in the terminal device. 4 to the arithmetic and control unit 41. These pieces of information are stored in the primary storage device 411 of the arithmetic and control unit 41 in step S520.

  The arithmetic and control unit 41 of the terminal device 4 activates a preinstalled three-dimensional information display program (step S521). In accordance with the activated three-dimensional information display program, the arithmetic and control unit 41 reads out the three-dimensional layout information centered on the designated product, which is received by the communication device 45 and stored in the primary storage device 411. A part of the dimension layout is displayed on the terminal device 4 (step S522).

  At this time, the work name or number may be read from the primary storage device 411 and highlighted. This 3D layout information is provided with a function that can perform operations such as changing the viewing angle, scaling, and confirming the selected product information, and buttons for selecting this function. Omitted.

  Finally, in step S523, the person in charge confirms the displayed three-dimensional layout information in addition to the information on the two-dimensional drawing, and confirms that there is no problem in the area to be worked on the next day. If it is necessary to change the work area, work time, etc., or to adjust with other work, the process proceeds to step S600 (see FIG. 3), that is, step S601 in FIG. If it is not necessary to change or adjust the work area or work time, the process proceeds to step S700 (see FIG. 3), that is, step S701 in FIG. Note that the process proceeds to step S600, for example, corresponding to selecting a process work from the process related information list L4 on the screen as shown in FIG. 15A (see FIG. 17) and pressing the “change” button. When proceeding to step S700, this corresponds to pressing the “end” button.

(Copy of 2D layout / 3D layout data to terminal device 4)
In the above description, as for the three-dimensional layout information, the terminal device 4 reads the data stored in the temporary storage device (not shown) of the three-dimensional layout information storage server 3. If the work is not changed), the assigned 3D layout information is copied to the storage device 42 of each terminal device 4, and the copied 3D layout information is used for the correction work. May be performed.

  Furthermore, as for the two-dimensional layout information, the information stored in the temporary storage device 115 of the calculation control device 11 of the work area display calculation device 1 has been described as being transmitted to the terminal device 4. When the dimensional layout information is generated by the work area display calculation device 1, it is copied to the storage device 42 of the terminal device 4 operated by each person in charge, and the copied two-dimensional layout information is stored in each terminal device 4. May be displayed.

  Thus, by copying the two-dimensional layout / 3-dimensional layout data to each terminal device 4, the responsiveness of each terminal device 4 can be improved. In addition, when the 2D layout / 3D layout including the process work information and the work area is changed for the purpose of the process work and the interference of this work area, the changed 2D layout / 3D layout data is changed each time. Are downloaded from the work area display calculation device 1 and the three-dimensional layout information storage server 3 and copied. A program for each device of this system is created so that such processing is automatically performed.

  In addition, when work time or work area is changed to solve problems such as interference work and up / down work, the change information is transmitted to the work area display calculation device and the process plan information storage server It is necessary to change the process plan information stored in 2 and the 3D layout information stored in the 3D layout information storage server 3. This is changed according to the procedure (described later) described in step S600.

  In the above description, it is assumed that three-dimensional layout information used in CAD design is used, but such three-dimensional layout information often requires a large memory area. Therefore, it may be difficult to actually download and view the three-dimensional shape as described above with a portable terminal device having a small size. Therefore, the information amount of the three-dimensional layout used in the CAD design is reduced and converted into a simple three-dimensional system that can be moved on the Internet, and work area information is added thereto.

(Work area adjustment work)
Next, a case where correction is made to the work area as a result of confirmation by the person in charge will be described with reference to FIG.

  When the person in charge instructs the operation to be selected and changed in step S520 (see FIG. 8) via the input device, the arithmetic control device of the terminal device 4 reads the change program from the storage device 42. Load and start (step S601). Next, a change enable / disable confirmation signal including information (for example, a work number) that can specify the work is transmitted to the work area display computing device 1 via the communication device 45 (step S602).

  When the work area display calculation device 1 receives the change permission confirmation signal (step S603), in step S604, the calculation control device 11 stores the address of the terminal device 4 of the person in charge in the primary storage device 115, and the storage device In the process related information list L4 stored in C123, it is determined whether or not the specified work can be changed. In this determination, the changing flag of the designated work (see FIG. 13) and the changing flag of another work that interferes with the designated work or is in a vertical work relationship are confirmed (step S605). Other interference work and up / down work are confirmed in lists L6 and L7, respectively, and when there are interference work and up / down work, the changing flag of these work numbers is confirmed.

  Note that this in-change flag is set to ON (= 1) by the arithmetic and control unit 11 when work information is being changed by any person in charge or the terminal device 4. In the above description, when the process work to be changed and other process work that interferes with this process work are not being changed in step S602 or S605, the changing flag of the process work to be changed is turned on ( = 1).

(When work information cannot be changed)
If the changing flag of the designated work or the work that interferes with the designated work or has a vertical relationship is turned on, in step S606, the arithmetic and control unit 11 passes the communication unit 15 through the communication device 15. The terminal device 4 is notified that the change is impossible. At this time, the work number for which the above-mentioned changing flag is on is also transmitted to the terminal device 4 together.

  In step S607, when the communication device 45 of the terminal device 4 receives a signal that cannot be changed, the arithmetic and control device 41 of the terminal device 4 sends a message to be displayed when the change-impossible signal is received in advance to the output device (display). Displayed so that the selected work and the work that interferes with the selected work or is in a vertical relationship can be discriminated on the screen. Such display is performed by highlighting the work area displayed in FIGS. 15A and 15B, for example. With such a display, the person in charge can confirm that another person in charge is changing the selected work or the work having an interference relationship or a vertical relation with the selected work. In such a case, after a while, the state where the change is possible is confirmed and the change process is performed. Alternatively, if the information indicating which other person in charge (terminal device) is changing is included in the above-mentioned change impossible signal, it is possible to make adjustments between persons in charge by direct telephone calls or the like.

(When work information can be changed)
If the change is possible, that is, if the change flag of the specified work and the work that interferes with or is in a vertical relationship is off (= 0), the change flag of the specified work is first set. Is turned on (= 1). (Step S608). Next, a message indicating that the change is possible is transmitted from the communication device 15 to the terminal device 4 of the person in charge who is working (step S609).

  When the arithmetic and control unit 41 of the terminal device 4 receives that it can be changed, it displays a menu for selecting the item to be changed on the output device 44 and makes the person in charge select it. Items displayed on the menu include items for changing process work information, items for changing the shape of the work area, items for changing the problem flag, and items for inputting comments, and buttons for each item are displayed. (See FIG. 17B). When the button is selected, an input screen is displayed corresponding to each item.

  In step S610, when the person in charge selects a button for selecting an item to be changed, a selection signal is input from the input device 43 and transmitted to the arithmetic and control unit 41, and parameters related to the contents of the item to be changed next and a change value. Is displayed on the output device 43 (input screen). FIG. 17C shows an example of an input screen displayed when “Change process work information” is selected.

  When “change process work information” is selected, an input screen (see FIG. 17C) is displayed so that the data in the process work information part of the process related information list L4 in FIG. 13 can be changed. For example, an area for inputting a work start date, a work end date, a work start time, a work end time, no work on the next day, and the like in the process related information list L4 is displayed on the output device 44, and a change from the input device 43 is accepted. “No work” refers to an item that is registered when the work area is not displayed because the work is not performed since it is a day from the work start to the end schedule. In order to make changes, information on the work that interferes with other work and the up and down work is also displayed for reference.

  When the change contents are input, the confirmation button is pressed and the end button is pressed again to return to the screen of FIG. If you cancel your changes, your entries will be erased. For safety, for example, when the end button is pressed without pressing the confirmation button, it is not changed. If the end button is pressed without changing anything, nothing is changed.

  When changing the shape of the work area, a screen for inputting data for changing the graphic information data of the definition information in the process related information list L4 is displayed on the output device 44, and the change from the input device 43 is accepted.

  When the change of the problem flag (interference work flag, upper / lower work flag) is selected, a screen for inputting the problem release flag of the process related information list L4 is displayed on the output device 44. Even when the problem flag (interference work flag, up / down work flag) is turned on in the process related information list L4, it may be possible to work simultaneously depending on the interfering process work. In such a case, the person in charge of the process work contacts and confirms, and data input for setting the problem release flag is performed from the input device 43 so that the problem flag can be released.

  Of the cases where the process change and work area shape change described above have been made, changes to avoid problems, such as changes in work time and work place (work area), are made three-dimensional based on the change information. Creation of the layout shape, writing to the two-dimensional layout, interference check are performed, and the problem flag is automatically turned off. Therefore, the problem flag can be canceled when it can be canceled for other reasons. For example, as described above, even if the work area shape interferes, it is a case where it is confirmed that the work is possible by discussion between the persons in charge and between the workers.

  In the comment input, an area for inputting the adjustment result or noticed item described above is shown on the output device 44 as in the case of changing the process, and can be input via the input device 43. This inputable information includes a change of deleting any comment that has been input.

  For the sake of clarity, FIG. 16 shows the influence on the process related information list L4 and the three-dimensional layout / two-dimensional layout for each of various change patterns that can actually occur in the input operation in step S610 described above. Shows a table.

  In step S611, when the person in charge presses the confirmation button on the screen of FIG. 17B and further confirms the value input on each input screen corresponding to the item to be changed, the arithmetic and control unit 41 changes on each screen. The obtained value is stored in the primary storage device 411 and transmitted to the work area display computing device 1 via the communication device 45 (step S612).

  At this time, when the change target information is process information, when the work area display calculation device 1 receives a signal to be changed from the terminal device 4, the calculation control device 11 stores the process related information list L4 stored in the storage device C123. The process work information is rewritten, change information (changer, change time) is added (step S614), and the change is reflected in the two-dimensional layout information (step S615).

  When the change information includes information related to the work start schedule, work end schedule, work start time, and work end time among the process work information, the process work information corresponding to the change is transmitted from the communication device 15 to the process plan information storage server. 2 (step S616). When receiving the signal from the communication device 25 (step S617), the arithmetic and control unit 21 of the process plan information storage 2 specifies the process work information of the target work of the process plan information stored in the storage device 22, and this process work Information is changed (step S618). When the change is completed, the calculation control device 21 of the process plan information storage server 2 instructs the communication device 25 to transmit a rewrite completion notification. The communication device 25 transmits a rewrite completion notification to the work area display calculation device 1 (step S619).

  Further, since the 3D layout information storage server 3 holds a copy of the process related information list L4, the process related information list L4 of the 3D layout information storage server 3 is also changed. The changed process work information is transmitted from the communication device 15 to the three-dimensional layout information storage server 3 (step S616). When the arithmetic and control unit 31 of the three-dimensional layout information storage server 3 receives the signal from the communication device 35 (step S620), it specifies the target work area shape of the three-dimensional layout information stored in the storage device 32, and stores the information. Rewriting is performed (step S621). When the rewriting is completed, the calculation control device 31 of the three-dimensional layout information server 3 instructs the communication device 35 to transmit a rewriting completion notification. The communication device 35 transmits a rewrite completion notification to the work area display calculation device 1 (step S622).

  When the rewrite of the process related information list L4 of the storage information C123 of the work area display calculation device 1 is completed and the rewrite completion notification is received from the process plan information storage server 2 and the three-dimensional layout information storage server 3, the calculation control device 11 The communication device 15 is instructed to transmit a change completion notification to the terminal device 4 of the person in charge who requested the information change. The communication device 15 transmits a change completion notification to the terminal device 4 (step S623). When the change completion notification is transmitted, the changing flag of the process related information list L4, which is stored in the storage device C123 and set to ON (= 1) in step S608, is changed to OFF (= 0). Return to the correct state (step S624).

  When the terminal device 4 used by the person in charge receives the change completion notification from the work area display calculation device 1 (step S625), the calculation processing device 41 of the terminal device 4 receives the reception notification from the communication device 45. Then, the output device 44 is instructed to output a predetermined message indicating the completion of the change. The output device 44 outputs a message. After confirming the message, the person in charge confirms the two-dimensional layout / three-dimensional layout information after the change as necessary (similar to steps S507 to S520). If there is another change as a result of the confirmation, the change process is selected (step S627), and the steps from step S602 for the change process are repeated. If there is no change, the change work ends.

  In the above description, information is changed for each work area or work number. However, it is also possible for a plurality of work groups scheduled to work on the next day on the floor to adjust or change process information while consulting with one terminal device 4 together. In such a case, the person in charge downloads the two-dimensional layout information for each floor from the work area display calculation device 1 to the terminal device 4 and collects the change information in the temporary storage device 411 of the terminal device 4 for each floor. Alternatively, a method may be adopted in which the change information is transmitted to the work area display calculation device 1 at once. With this method, it is not possible to confirm drawings other than the floor in charge, but there is no need to communicate with the work area display computing device 1 each time an item is selected and changed as described in step S610. The operation speed of the terminal device 4 can be increased.

  In addition, although detailed explanation is omitted, when changing the problem flag (interference work flag, up / down work flag) so that process work can be performed as safely and reliably as possible, the status of the work area concerned was confirmed. Whether or not confirmation is performed for each work area of the two-dimensional layout may be provided in the process related information list L4. For example, in FIG. 17B, when the problem flag button is pressed to change the state of the problem flag (interference work flag, up / down work flag), the screen shown in FIG. 17B is related. Select the work area and mark it as confirmed. In correspondence with this mark, the confirmation flag for each work area may be turned on.

(Publication of interference in the work area to all workers)
Each work area determined through the adjustment of the work area described above indicates a work range of each process work (work of each work number) performed on the next day. Further, according to the work contents of each process work, restriction information (restriction mark) related to safety such as strict prohibition of use of fire or work at high places is also included in the data of each process work in the process related information list L4. The contents of the restriction information are described in “Restriction contents” included in the work area information of the process related information list L4 (see FIG. 13). In the example of FIG. 13, two tasks (system number Nos. 1 and 2) are different tasks, and have different safety restrictions. Correspondingly, different display marks (display marks 1 and 2) are given.

Although omitted in the above description, in the work area interference detection system of the present invention, these safety-related restriction information is also displayed together when displaying the two-dimensional layout / three-dimensional layout data. (For example, refer to FIG. 15A) Therefore, it is desirable that all workers can confirm the display of the work area. For this reason, in step S700, an example of a procedure of disclosure to all workers in the work area determined above is shown, and in step S800, an example of a procedure that the worker confirms from the terminal device 4 is shown. This will be described with reference to FIGS.
In FIG. 15A, the Δ mark in the figure represents the restriction information, but is an example of these illustrations, and does not indicate the information described in the related information list L4.

  Up to step S600 in FIG. 3 described above, history information management of whether the worker has confirmed the information on the work area determined above or management of whether all the work has been confirmed is not performed. . As daily routine work for each worker, information is made public at a certain time. Therefore, only the information for the current day can be confirmed before a certain time, and the information for the current day and the next day can be confirmed after a certain time.

  First, in step S701, when a certain time comes, the work area display calculation device 1 starts a program for generating work area information to be disclosed (referred to as a “work area disclosure program”).

First, the two-dimensional layout information describing the work area is disclosed. The work area display calculation device 1 picks up the date of the next day from its own calendar system (step S702), and specifies the process work to be performed on the next day from the process related information list L4 stored in the storage device C123 (step S702). S703). It is confirmed whether or not there is no work flag for the specified process work (step S704). The information on the process work when there is no work flag is information that is not required to be displayed, so it is not disclosed. If there is no work non-flag, the public flag is changed from private (= 0) to public (= 1) (step S705).
Further, the operations from step S703 to step S705 are performed for all the process operations on the date (step S706).

  Next, in step S707, the date (the current day, the next day) so that the information can be easily selected on a screen displayed in a confirmation program (referred to as “work area confirmation program”, which will be described later) activated by the worker. ) And the process work data on the date are generated in a format such as a table (list L8) as shown in FIG. 18, for example, and stored in the storage device 12 as file data with a predetermined name. In the example shown in FIG. 18, it is set so that the process work on the current day (2011/5/4) and the next day (2011/5/5) can be confirmed.

(Confirmation of work area related to each worker)
A procedure for confirming the next day's work for each worker to confirm the two-dimensional layout information of the process work set as openable above will be described. This procedure is a procedure including the determination (input) by the worker himself and the operation of the terminal device 4, the work area display calculation device 1, and the three-dimensional layout information storage server corresponding thereto, and is indicated by a double line frame. The step is an input step by a worker. In this procedure, it is impossible to change the displayed information, but it is assumed that information on whether or not the worker has confirmed (described later) is automatically transmitted to the work area display computing device 1.

  Each worker first activates a program (referred to as a work area confirmation program) installed in advance in the terminal device 4 for confirming the work area (step S801). When starting the program, for example, as shown on the left side of FIG. 19A, a message for starting the program “work area check start” is displayed, and the name and password of the operator (worker) of the terminal device 4 are displayed. Enter. The name and password information is transmitted to the work area display computing device 1, and when it is confirmed that the use of the program is permitted, an activation permission signal is sent from the work area display computing device 1 to execute the program. It is activated. Simultaneously with the start of the program, the list L8 generated in the above step S707 is downloaded from the storage device of the work area display computing device 1.

  When the work area confirmation program is activated, the arithmetic processing unit 41 of the terminal device 4 displays on the output device 44 a screen (hereinafter, GUI) that is easy for the user to use to display the data of the list L8. Instruct. (Step S802). On the right side of FIG. 19 (a), as an example of such a GUI, an example of a GUI for selecting a work day and a building by displaying them in a pop-up menu format is shown.

  In step S803, the worker selects a date, a building, and a hierarchy (floor) to be confirmed. The arithmetic processing device 41 transmits the date and building / hierarchy (floor) information from the input device 43 to the work area display arithmetic device 1 via the communication device 45 and also transmits a floor two-dimensional layout information transmission request. .

  In step S804, when the communication device 15 of the work area display computing device 1 receives the signal, information on the process work that is made public among the process work in the process related information list L4 of the storage device C123, that is, input in step S803. The process work that can be disclosed under the specified conditions is selected, and the information of the process related information list L4 is transmitted to the terminal device 4. Further, the two-dimensional layout information is selected from the storage device D124 and the information is transmitted to the terminal device 4.

  In step S805, when the communication device 45 of the terminal device 4 receives the process related information list L4 and the two-dimensional layout information signal, the arithmetic control device 41 stores the information in the storage device 42 and the arithmetic control device 41. Displays the two-dimensional layout information and the process work information of the process-related information list L4 on the output device 44. FIG. 19B shows a screen for performing the same display as FIG. 15A, FIG. 17A, and FIG.

  Next, in step S806, the person in charge determines whether or not to confirm more detailed information on the process work. If more detailed information is to be confirmed, the process proceeds to step S807. If the confirmation is unnecessary, the process proceeds to step S810, and the arithmetic and control unit 41 executes a completion operation.

In step S807, a process work is selected from the two-dimensional layout or work name list displayed on the output screen (see FIG. 19B).

  In step S807, when the processing unit 41 receives information indicating which process work has been selected from the input device 43, the process work information of the selected process work is, for example, as shown on the right side of FIG. It is displayed on the output device 44.

  When the person in charge performs the processes in steps S806 and S807, a three-dimensional layout may be displayed (step S809), and a process operation may be selected in the displayed three-dimensional layout. The display of the work area in the 3D layout is performed by accessing the 3D layout storage server via the display of the published work area of the 2D layout (see FIG. 15) as described in step S510 above. Thus, the data of the 3D layout corresponding to the 2D layout is downloaded.

  In step S808, when displaying the process work information of the selected process work, the arithmetic processing device 41 reads the information from the storage device 42, and the output device 44 displays this information.

  When the work for confirming the work area is completed in the above work, in step S810, the arithmetic and control unit 41 performs a confirmation completion process and finishes the operation of the work area confirmation program. In the confirmation completion process, the input data (selection operation) of the person in charge at steps S803, S806, and S807 is transmitted to the work area display arithmetic device 1. The work area display computing device 1 can check whether the person in charge has confirmed the contents of the process work in charge of the person in charge from the data input in these steps.

  In addition, when the display space of the output device 44 of the terminal device 4 is not sufficient, a list of only key information (for example, work name and work place) among the process work information is displayed, and other information or two-dimensional information is displayed. The layout may be displayed when the operator selects.

Includes a three-dimensional layout information storage server 3 that generates layout data including

  In a plurality of process operations, if the time schedule does not interfere, the interference in the work area does not become a problem. However, in the process operation in which the schedule interferes, it is necessary to check the interference in the work area. In this system, the work area display computing device 1 which is a higher-level control device of the system detects such work area interference, generates layout data including interference information of the work area of the process work, and The apparatus 4 can display the interference state of the process work in an easy-to-understand manner.

The arithmetic control device renders the work area as layout data and detects interference of the work area. The storage device stores various data (information in the process related information list L4) necessary for rendering the work area and detecting interference in the work area. The work area display computing device has a function of controlling the entire work area interference detection and adjustment system, and exchanges data with the process plan information storage server 2, the three-dimensional layout information storage server 3, and the terminal device 4. And control processing and display operations in the terminal device. The person in charge of adjustment of the entire process work manages the operation of the entire work area interference detection and adjustment system, and inputs and changes various data from the input device of the work area display arithmetic unit if necessary.
