Abstract

PURPOSE:To eliminate process delay due to improper arrangement of equipments by judging whether there is a high-low level difference generated on the ground surface in a working area, and deciding whether or not the input arrangement of the equipments is adequate and displaying the decision result. CONSTITUTION:The part where the high-low level difference is generated on the ground surface in the working area is discriminated from input data regarding the level of the ground surface in the working area to decide whether or not the input arrangement of the equipments is proper and displays the decision result. Consequently, when data for arranging an equipment which can not be arranged on a nonparallel surface on a nonparallel place in the working area such as the step part where the ground surface has a high-low level difference, a slanting part 34 which has larger than a specific angle, etc., it is decided that the arrangement of the equipment is adequate and the decision result is displayed. For example, a warning message 'The position of a crane main body is in an arrangement inhibited range' is displayed. Consequently, process delay is prevented from being caused owing to the improper arrangement of the equipment.

Description

[Detailed Description of the Invention] Industrial Application Field] The present invention relates to a construction work simulation device, and in particular,
The present invention relates to a construction work simulation device that supports planning and process management of construction work by displaying a schedule and a status map.

[Conventional technology: As is well known, construction work is carried out using so-called construction equipment such as excavators and lifting machines. These construction equipment are moved around the work site as the construction work progresses, but in order to operate efficiently by reducing the number of times and amount of movement, it is also necessary to improve the physical feasibility of the work, such as the arrangement of equipment. This method is effective in shortening the period of construction work.

However, it is a complicated task to draw up a schedule for construction work in consideration of the amount of movement of construction equipment, the number of times it will be moved, and the physical possibility of arranging the equipment. Further, there are problems in that it takes a long time to formulate a process plan, and that process delays may occur when changes are made to the process plan.

For this reason, Shigehito has proposed a construction work simulation device that supports the formulation of process plans by simulating construction work. This construction work simulation device enables process planning by displaying on a screen, etc., a process chart showing the order of work and a status map showing the location of construction equipment overlaid on a floor plan of the work site. support. The operator can refer to the original drawing of the process chart to determine the overall flow of the work while creating a process chart, and also refer to the original drawing of the situation chart to create a situation map and determine the detailed layout of construction equipment. can. Thereby, it is possible to easily formulate a process plan that allows the work to be performed physically and allows efficient operation of construction equipment. In addition, the process chart shows the overall flow of work, so it can support process management, and the status map shows the arrangement of construction work equipment as an image of the work site, so after drawing up the process plan, the actual construction work can be carried out. can support.

[Problem to be solved by the invention]

However, during construction work, work such as excavation of the ground may cause differences in elevation on the ground within the work site. Also,
When constructing a building on a slope, the ground within the workplace is non-level. In such cases, depending on the type of construction equipment, there may be locations within the work site where it cannot be placed, or it may not be possible to move the equipment across areas with differences in height. Conventional construction work simulation devices display the placement of construction equipment in a situation map according to the input data, so in the above case, even if it can be displayed on the screen, it is difficult to actually place the equipment. This sometimes resulted in the need to change the process plan, resulting in process delays.

The present invention has been made in consideration of the above facts, and is a construction work simulation in which equipment can be placed in the appropriate position j = without causing process delays due to improper placement of equipment. The purpose is to obtain a non-contact device.

[Means to solve the problem]

In order to achieve the above object, the construction work simulation device according to the present invention includes an input means for inputting at least work order data, equipment arrangement data, and data regarding the height of the ground in the work place, and processing means for creating a process chart representing the order of work based on the work order and a situation map showing the arrangement of equipment superimposed on the floor plan of the work place; A determination means that determines the parts of the plant where there are differences in height and determines whether or not the input arrangement of equipment is appropriate; a process chart and status diagram created by the processing means; and the determination results of the determination means. and display means for displaying.

In the invention, the height difference of the ground in the workplace is determined based on the input data regarding the height of the ground in the workplace, and it is determined whether the input arrangement of equipment is appropriate or not. Make a judgment and display the judgment result.

20. Therefore, if the data for placing equipment on a non-horizontal surface of the workplace, such as a step where there is a difference in ground level, a certain corner, or a slope of more than a room, is manually placed, the equipment should be placed. It is possible to judge that the difference in height is not appropriate and display the judgment result, and also to display the judgment result when the data for arranging equipment that cannot be moved in parts with height differences in the workplace so as to move the parts with height differences is manually generated. It is also possible to determine that the equipment placement is inappropriate and display the determination result.

Therefore, since the equipment can be placed at appropriate positions, there is no need to change the process plan, and no process delays occur due to incorrect placement of the equipment.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

As shown in FIG. 1, the construction work simulation device 10 according to the present embodiment is composed of a personal computer 12 and various input/output devices connected to an input/output capacitor 20 of the personal computer 12. be done. The personal computer 12 includes a CPU 14, a ROM 16, and an R
It includes an AM 18 and a human output port 20, which are connected to each other by a bus. In this embodiment, the input/output devices connected to the input/output port 20 include programs from storage media such as floppy disks and hard disks;
An external storage device 32 for reading data and writing data to the storage medium, a keyboard 24 and a mouse 26 for the operator to input data, etc., a display 28 for displaying processing results, and printing the processing results. A printer 30 is used for printing.

A program for causing the personal computer 12 and each human-powered device to function as the construction work simulation device 10 is stored in the storage medium. This program is read and executed when each device constituting the construction work simulation device 10 is powered on.

Next, the operation of this embodiment will be explained using an example in which a process plan for cast-in-place pile work, which is one of the foundation works, is drawn up.

The construction work simulation device 10 of this embodiment performs processing as shown in the flowchart of FIG. 12 when supporting the formulation of a process plan. That is, in step 100, the operator is instructed to manually enter data specific to the construction site from the start of the construction work to the end of the construction work to be simulated. Thereby, the operator inputs data such as the floor plan of the work place, the arrangement and size of the piles, and holidays during the work process period. Note that the plan view data of the work and location are drawn on the screen of the display 28 using the CAD function of the personal computer 12. In addition, if there is a height difference in the ground within the workplace, for example, if there is a slope 34 as shown in Figure 4, the operator will need to know the positions of both ends of the slope 340, the slope angle, etc. as data unique to the workplace. Enter data. This is due to the lack of work where there is a slope 34.
If equipment is placed on a slope, there is a risk that the equipment will overturn, and if equipment is placed on a horizontal portion near both ends of the slope 34, there is a risk that the slope will collapse, the equipment will overturn, etc. It is from. When the second data is input, the construction work simulation device 10 processes the slope 34 and a range separated by a predetermined distance from both ends of the slope 34 as a prohibited range for the placement of construction equipment, as shown in FIG.

In step 102, names and sizes of so-called temporary facilities such as a muddy water plant for treating muddy water and a reinforcing bar processing table for processing reinforcing bars, etc.
Instruct to input data such as location. Step 10
Step 4 instructs the user to input data regarding excavators and lifting equipment, so-called cranes, which are construction equipment used when performing cast-in-place pile work. As a result, for excavators, data such as the number of excavators used for work, the model of each excavator, excavation thickness, turning radius, etc. are manually input, and for lifting machines, the number of machines used for work, the model of each lift machine, boom length, etc. Data such as the maximum allowable load for the load is input.

The construction work simulation device 10 performs step 100
Based on the basic data manually generated in step 106, an original diagram 36 of a process chart and an original diagram 38 of a status diagram for each minimum unit of a process (half a day in this embodiment) as shown in FIGS. 2 and 3 are created, for example. The original drawing 36 of the process chart can display the steps of each work in units of several days (in this embodiment, in units of 16 days).

Further, in the original drawing 38 of the situation map, as an example, a mud water plant, a reinforcing bar processing table, etc. as temporary structures are shown superimposed on the plan view of the workshop, and the arrangement of each piece of equipment can also be shown superimposed. In addition, in Fig. 3, "○" indicates the arrangement of the piles, and the ASB
The symbols 1, B1, . . . and the numbers 1, 2, 3, . . . are used to represent various coordinates. Each type is given a number (not shown) for convenience, and the size of the "○" is 5, corresponding to the diameter of the pile.

In step 106, the original drawing 3 of the process chart is displayed on the display 28.
6 is displayed and data regarding the excavation work is input for each minimum unit of the process to set the process of the excavation work.

Hereinafter, the detailed process of setting the excavation process of the steer bar 106 will be explained with reference to the flowchart shown in FIG. Note that the flowchart in FIG. 13 shows the setting process of the excavation process for each minimum unit of process.

In step 120, the original drawing 36 of the schedule as shown in FIG. 3 is displayed on the screen of the display 28, and a message requesting human labor for the excavation work data is displayed to request human labor for the data related to the excavation work. In step 122, it is determined whether data has been input. If there is no input, return to step 120, and continue to step 12 until input is received.
0 and repeat step 122. The operator refers to the message and inputs data such as the work date and time, the pile number indicating the work location of the excavator, the excavator number, and the direction of the excavator. If data about the excavator is entered,
As shown in FIG. 5, the pile number indicating the work location of the excavator and the arrow 56 indicating the direction of the excavator are displayed on the original drawing 36 of the process chart, and the process proceeds to step 124. Furthermore, the arrangement (position and excavation direction) of the excavator 42 as shown in FIG. 6, for example, is displayed on the original drawing 38 of the situation map corresponding to the input work date and time.

In step 124, it is determined whether the location of the excavator determined from the input data is outside the above-mentioned location prohibited range. The location of the excavator is determined by the number of the pile to be excavated and the direction of the excavator. If the location of the excavator is within the prohibited placement range (for example, the position indicated by arrow A in FIG. 4), a negative determination is made in step 124, and a warning is issued in step 126 stating, "Excavator placement: within the prohibited placement area." Display messages. In this case, since it is not possible to arrange the excavator in the specified arrangement, the process returns to step 120 and requests for input again. This prevents the excavator from being placed on a non-horizontal portion such as the slope 34, and allows the excavator to be placed at an appropriate position.

If the excavator is placed outside the prohibited area (for example, the 4th
In the position shown by arrows B and C in the figure), step 134
Determine whether there is a planar overlap between the position of the pile to be worked on and the temporary structure. For example, in FIG. 8, the pile 46 and the reinforcing bar processing table 48, which is a temporary structure, are doubled in plan. In such a case, the excavation work cannot be performed unless the reinforcing bar processing table 48 is moved. Therefore, step 13
4 is negative, and in step 136, a warning message "There is an overlap between the pile and the temporary structure" is output, and the process moves to step 146.
In this case, the process moves to step 138 without executing step 136.

In step 138, it is determined whether or not there is a planar overlap between the excavator and the temporary structure. For example, in Figure 8, the excavator 50
and a muddy water plant 52, which is a temporary structure, overlap in plan. In such a case, the excavation work cannot be performed unless the muddy water plant 52 is moved. Therefore, the determination at step 138 is negative, and at step 140 a warning message stating "excavator overlaps with temporary structure" is output, and the process moves to step 146. If the excavator and the temporary structure do not overlap, the process moves to step 142 without executing step 140.

In step 142, it is determined whether or not there is a planar overlap between the turning range of the excavator and the temporary structure. The turning range of the excavator can be determined from the turning radius of the excavator. Step 1
If the determination in step 42 is negative, excavation work can be performed, but the excavator cannot be turned. Therefore, in step 144, a warning message is output saying "The excavator's turning range overlaps with the temporary structure", and step 1
46. If there is no overlap between the turning range of the excavator and the temporary structure, step 144 is not executed and step 1 is performed.
46.

In step 146, it is determined whether the data requested and input in step 120 is to be registered as excavation process data. The operator can easily determine whether the input data is appropriate by referring to the displayed warning message. If it is determined that the data is not appropriate, data indicating the result of the determination that the data is inappropriate is input.

As a result, the determination at step 146 is negative, and the process returns to step 120 to request input again. At this time, if the direction of the excavator in the newly manually input data is different from the direction of the excavator in the previously input data, the direction of the arrow 56 displayed on the original drawing 36 of the process chart and At the same time, the direction of the excavator displayed on the original diagram 38 of the situation map is corrected. For this reason, the Nomura/yon device 10 for construction work
Easy to operate.

If it is determined that the data is appropriate, data indicating the result of the determination that the data is appropriate is input. As a result, the determination in step 146 is affirmative, and the input data is registered in step 148. Also, message data is registered at the same time as the data of this excavation process is registered. This message data indicates which warning message was displayed among multiple warning messages indicating the overlap between the excavator and the temporary structure, and is registered as situation map data corresponding to the manually entered date and time data. In addition, when this status diagram is displayed from now on, it will be referred to and a warning message will be displayed together with the status diagram. An excavation process is set by repeating the above process for each minimum unit of process.

After the setting of the excavation process is completed, the original drawing 36 of the process chart is displayed on the display 28 in step 108 of the flowchart shown in FIG. and set the process for each work. As a result, data such as the work date and time, the number of the pile to be worked on, etc. are input, the pile number is displayed numerically on the schedule, and the steps for concrete pouring work and reinforcing bar cage assembly work are set. Note that there are days when concrete cannot be supplied for concrete pouring work, and a check process may be performed in step 108 so that concrete pouring work cannot be set on those days. Through the above processing, the process chart 40 is completed by displaying the steps of each work on the original drawing 36 of the process chart as shown in FIG. 5, for example.

In step 110, the original status map 38 showing the arrangement of the excavators is displayed on the display 28, and the arrangement of the lifting machines for each minimum unit of the process is set.

Hereinafter, detailed processing of setting the arrangement of the lifting machines in step 110 will be explained with reference to the flowchart shown in FIG. 14.

Note that the flowchart in FIG. 14 is executed every time the arrangement of the lifting machines in each situation diagram is set.

In step 150, a situation diagram 38 showing the arrangement of the excavator 42 as shown in FIG. 6 is displayed on the screen of the display 28, and a message for inputting the lifting machine data is displayed to input the lifting position data and the lifting machine data. Request input of weight data of the object to be lifted. In step 152, it is determined whether data has been input. If there is no input, return to step 150, and continue at step 150 until input is received.
and repeat step 152. The operator refers to the message and manually inputs the lifting position data and the weight data of the object to be lifted. If data has been input, the process moves to step 154.

In step 154, a lifting performance curve of the lifting machine to be used, that is, a curve showing the relationship between the boom length of the lifting machine and the maximum allowable load as shown in FIG. 9 is created. There is an inverse relationship between the length of the boom of a lifting machine and the maximum allowable load.
Basic information on the lifting machine can be created based on the maximum permissible load of the lifting machine that was entered during manual labor. The created performance curve is displayed as a performance curve 54 together with the original diagram 38 of the situation diagram, as shown in FIG.

In step '7 156, a message is displayed requesting manual input of the position data of the main body of the lifting machine. In step 158, it is determined whether or not lifting machine main body data has been input. If there is no human power, the process returns to step 156, and steps 156 and 158 are repeated until there is input. The operator refers to the message and inputs the position data of the lifting machine body.

The input of this position data is performed by moving the cursor to a position corresponding to the position of the lifting machine body in the situation diagram and pressing a key indicating the end of input. If data has been input, the process moves to step 160.

In step 160, the length of the boom determined from the lifting position of the lifting machine and the position of the main body of the lifting machine is calculated. In step 162, the line 58 shown in FIG. 10 is displayed at the corresponding position on the performance curve 54 based on the boom length determined in step 160, and the maximum allowable load determined based on the boom length and the peak of the performance curve. is displayed near the performance curve 54.

Thereby, the operator can easily determine whether the lifting machine can lift the object to be lifted.

In step 164, it is determined whether the lifting machine can lift the object to be lifted, that is, whether the maximum allowable load is greater than the weight of the object to be lifted. If it is determined that the lifting machine cannot lift the object to be lifted, the process returns to step 150 and requests the lifting machine to input the lifting position data and the weight data of the object to be lifted again. As a result, the operator can set the relationship between the lifting position of the lifting machine and the position of the main body of the lifting machine to an appropriate arrangement by referring to the display of the performance curve 54 and the maximum allowable load displayed again in step 154. can.

If it is determined in step 164 that lifting is possible, the process moves to step 166.

In steps 166 to 172, it is determined whether the position of the lifting machine body is appropriate, similar to the setting of the excavation process. That is, in step 166, it is determined whether the input position of the lifting machine body is outside the above-mentioned prohibited placement range. If the input position of the lifting machine body is within the prohibited placement range, the determination in step 166 is negative, and in step 168,
Displays a warning message that says, "The position of the lifting machine is within the prohibited area." In this case, it is not possible to place the lifting machine body in a manually operated position, so step 150
Go back and request input again. This prevents the lifting machine body from being placed in a non-horizontal portion such as the slope 34 by mistake, and allows the lifting machine to be placed at an appropriate position.

If the input position of the lifting machine body is outside the prohibited placement range, it is determined in step 170 whether or not there is a planar overlap between the lifting machine body and the temporary object. If there is an overlap, a warning message is displayed in step 172 saying "There is an overlap between the lifting machine main body and the temporary structure," and the process proceeds to step 17.
Move to 4.

If there is no overlap between the lifting machine body and the temporary object, the process proceeds to step 174 without executing step 172.

In step 174, step 150 and step 15
4, it is determined whether or not the input data is to be registered as the lifting machine arrangement data by displaying the message. The operator can easily determine whether the input data is appropriate by checking whether a warning message is displayed and by referring to the performance curve 54. If it is determined that the data is not appropriate, input data indicating the result of the determination that the data is not appropriate. As a result, the determination at step 174 is negative, and the process returns to step 150 to request input again. If it is determined that the data is appropriate, data indicating the result of the determination that the data is appropriate is input. This allows step 1
If the determination at step 74 is affirmative, the input data is registered at step 176.

Also, message data is registered at the same time as the placement data of this lifting machine is registered. This message data indicates whether or not a warning message indicating the overlap between the main body of the lifting equipment and the temporary structure has been displayed, and is registered as the data of the situation map and is referenced when displaying the situation map from now on. A warning message is displayed along with a status diagram. The above process is repeated for each situation map to set the arrangement of the lifting machines.

After the setting of the arrangement of the lifting machine is completed, in step 112 of the flowchart of FIG. Instruct the staff to manually arrange the placement of other equipment, such as dump trucks and concrete mixer trucks, for each unit process. As a result, the arrangement of the equipment for each minimum unit of the process is input, the arrangement of each equipment is all set, and a situation diagram 44 as shown in FIG. 7 is completed as an example. In the situation diagram 44, rM represents a concrete mixer truck, rDJ represents a so-called dumping force, "U" represents a so-called power shovel car, and rZj represents a tank for storing excavated soil. In step 113, movement of the temporary object is set.

Hereinafter, details of the movement setting of the temporary object will be explained with reference to the flowchart of FIG. 15. The flowchart in FIG. 15 is executed for a situation diagram in which the excavation machine or the lifting machine body and the temporary structure overlap. Note that it is possible to determine whether or not there is an overlap by determining whether data is registered in the message data described above.

In step 182, a situation diagram is displayed. Step 184
Now refer to the message data mentioned above and display the registered warning messages. Step 186 displays a message requesting input to move the arrangement of the temporary structure. In step 188, it is determined whether or not there was human power. If there is no input, step 188 is repeated. The operator refers to the message displayed in step 186 and inputs data for moving the arrangement of the temporary object. When the data is input, the determination in step 188 is affirmative, and the process moves to step 190. In step 190, it is determined whether or not the cause for displaying the displayed warning message has disappeared based on the operator's input. For example, as shown in Figure 11, if the warning message "There is overlap between the excavator and temporary construction" is displayed due to the overlap between the excavator itself and the muddy water plant; If the position is changed to Figure 11, it is determined that the factor has not disappeared,
When the direction of the excavator is changed to the position shown in FIG. 11, it is determined that the cause has disappeared.

If it is determined that the cause has disappeared (no), the process returns to step 186 and steps 186 to 190 are repeated until the cause has disappeared. If it is determined that the cause has disappeared, the displayed warning message is erased in step 192, the message data is updated in step 194, and the process ends.

The above processing is performed for all situation diagrams in which the excavator or lifting machine main body and the temporary object overlap, and the setting for moving the temporary object is completed.

As a result, in a process where there is an overlap between the excavator or lifting machine main body and the temporary structure on the situation map, the arrangement of the temporary structure is changed and the overlap is eliminated, so work can be performed based on the situation map. Further, when the direction of the equipment shown in the status diagram 44 is corrected, the direction of the arrow 56 displayed on the process chart 40 is corrected at the same time. Therefore, the construction work simulation device 10 has good operability.

The process planning is completed by the above processing, and in step 114 of the flowchart of FIG.
to store the data corresponding to the completed process chart 40 and status diagram 44 in the storage medium, and operate the printer 30 as necessary to print the process chart 40 and status diagram 44, and end the process. .

The construction work simulation device 10 can read, display, or print data corresponding to the process chart 40 and status map 44 stored in a storage medium as needed. This makes it possible to support process management and actual work. Furthermore, as a display method, it is also possible to perform continuous output, which continuously displays a status diagram for a specified period along the flow of the process.

In this way, in this embodiment, the arrangement of the temporary objects can be moved, so that the arrangement of the temporary objects can be determined appropriately, and process delays will not occur due to improper arrangement of the temporary objects.

In addition, in this embodiment, when human power is used to correct the direction of the excavator that has been input, the direction of the excavator shown in the situation diagram 44 is corrected, and the direction of the excavator shown in the process chart 40 is corrected. Since the information is displayed, the operability of the nucleation device 10 for construction work is improved.

Furthermore, in this embodiment, the lifting performance curve 54 of the lifting machine is displayed together with the situation diagram, so that it can be easily determined whether the lifting machine is capable of lifting the object to be lifted.

Further, in this embodiment, when an input is made to place the excavator and the lifting machine main body on the slope 34, it is determined that the arrangement of the excavator and the lifting machine main body is not appropriate, and a warning message is displayed. The excavator and lifting equipment can be placed in the correct position, eliminating process delays caused by incorrect equipment placement.

In addition, in this embodiment, the construction work simulation device 10
The explanation has been given by taking as an example the planning of a process plan for cast-in-place pile work, which is one type of foundation work, but the present invention is not limited to this, and can also be applied to other works, such as continuous underground wall work, for example.

In addition, in this embodiment, as part of the process of determining the parts of the workplace where there is a difference in ground level and determining whether or not the placement of manually operated equipment is appropriate, However, the movement of equipment was determined based on the equipment placement in the previous process, and equipment that could not be moved in areas with height differences in the work site was moved. Processing may be performed to prohibit input of layout data for moving a certain portion of the slope, for example, the slope 34.

Further, messages such as warning messages displayed by the construction work simulation device 10 are not limited to the messages described in this embodiment, and other messages having similar meanings may be displayed.

Furthermore, in this embodiment, the inputting and setting processing of each piece of information is shown in order from step 100 to step 112 in FIG. Processing can also be performed in a permutation other than that shown in the figure.

〔Effect of the invention〕

As explained above, in the present invention, it is possible to determine the parts of the workplace where there are differences in ground level, determine whether or not the manually placed equipment placement is appropriate, and display the determination results. This provides an excellent effect in that the equipment can be placed in an appropriate position, and process delays will not occur due to incorrect placement of the equipment.
