Description

  The present invention relates to a work support apparatus related to selection of a work tool.

  In recent years, power generation using various energy sources has been performed worldwide. Some of these include liquefied natural gas, nuclear power, coal-fired, oil-fired, and hydropower. In the field of electric power, the best combination in consideration of supply stability of energy sources, environmental compatibility, and economic efficiency is important, and nuclear power generation plays a part in this. When constructing or managing a plant such as a nuclear power plant, work such as installation and removal of equipment used in the plant is performed using a work tool such as a heavy machine such as a crane. In addition to the installation and removal work performed by one heavy machine, work by another heavy machine or other than the heavy machine may be performed in parallel or continuously in time at a nearby location.

  Safety is required for work with heavy machinery. That is, the basic condition is that the building of the plant, the equipment to be installed or removed, or the components of the heavy machinery do not interfere with each other. The heavy machine hangs the target device from the hook and moves the hook up and down using a wire. In many cases, heavy machinery is operated by adjusting the hoisting angle of the boom to set a range where the wire can reach, and turning the main body to determine the arrangement of the boom. Equipment is installed and removed by combining these operations, but it is required that the above-described interference does not occur during the work period.

  In addition, as a specification of heavy machinery, there is a rated load indicating the maximum mass that can suspend the target devices. The rated load is determined by the working radius obtained from the boom angle, the mass of the counterweight mounted on the heavy machinery, the engine output of the heavy machinery, and the like. That is, the rated load varies depending on the type of heavy machinery. In the installation or removal work of equipment, the working radius range is determined based on the mass of the equipment to be worked (referred to as the target equipment as appropriate) and the rated load of the heavy equipment to be used. In order for the heavy machinery to suspend the target equipment safely, the hoisting angle of the boom needs to be limited by the range of this working radius. Furthermore, in order to carry out the work safely, when setting the boom hoisting angle within the working radius, in other words, within the restricted range, the ground contact part of the crane does not exceed the crane working area. Furthermore, it is required that the heavy machinery can take an attitude that does not cause interference with the building, the target device, and the components of the heavy machinery. If the heavy equipment cannot take the posture to install or remove the target equipment within the working radius, the heavy equipment with specifications that can carry out the work, i.e., the rated load and boom shape, etc. Re-planned to work on introduction.

  When planning a work plan for installation or removal by heavy machinery, it is necessary to calculate the posture that the heavy machinery should take in order to satisfy the conditions for safely performing the work as described above for all target devices. When it is not possible to calculate the attitude of a heavy machine that satisfies such conditions, heavy machines having different specifications are used, and the attitude of the heavy machine that satisfies the conditions regarding the target devices is calculated. In general, a large heavy machine has a sufficient load rating and can be set to a wide working radius when suspending target equipment with a large mass, while the boom shape and the like increase to avoid interference. It may be difficult to take a posture. In the case of small heavy machinery, the shape of the boom is small, so it is easy to take a posture to avoid interference, but the range of working radii when hanging high-mass target devices with a small rated load margin is reduced. there is a possibility.

  Thus, heavy machinery has various shapes and rated loads depending on the model. In addition, since the operation speed varies depending on the model, the working time varies depending on the model of heavy equipment to be used even for the same target device. In addition, depending on the plant where the work is performed, the requirements for the safety of work by heavy machinery may differ. For example, in work on land where strong winds often blow during the work period, a larger margin is provided for avoiding interference between buildings, equipment, and heavy machinery. By doing so, there is a case where interference does not occur even if a shake occurs due to the strong wind, and safety is ensured. In addition, an object such as rubble that is not described in the design drawing of the building but is present on the site needs to be avoided. Furthermore, heavy equipment used for work can be rented from a company with many models. In this case, the rental fee varies depending on the type of heavy machinery.

  In this way, when planning installation or removal work with heavy machinery, it is considered that the work can be completed within a time that does not affect other work in addition to being able to install or remove the target equipment safely. It is necessary to do. In addition to this, it is important to select heavy equipment models, including considerations for safety requirements that vary from plant to plant, and fees related to rental of heavy machinery. In addition to the drawings of the building of the plant to be worked on, the user can use the drawings of dozens or more of the work target equipment depending on the plant, the drawings and specifications of multiple heavy machines that can be used, etc. It is necessary to formulate a plan that can realize the above, and to select a heavy machine to be used in the plan.

  Therefore, a technology for supporting selection of heavy machinery using a computer or the like has been developed. For example, Patent Document 1 discloses a plant construction / construction plan support apparatus and method for grouping a large number of operations included in plant construction work for each repetitive operation of the same type and grouping them into a group of operations. Has been.

  In Patent Document 2, a computer stores a three-dimensional skeleton diagram D in which the position, weight, and shape of each member of the structure skeleton are recorded. Further, a construction crane planning method and program in which the database T in which the lifting performance and posture, minimum working radius, and danger radius that can be in conflict with the crane base are recorded is also disclosed. Yes. The technique described in Patent Document 2 is to enter a crane movable range on a skeleton figure D, divide the skeleton figure D into a construction square Ei with a construction order, and for each construction square Ei, the construction square Ei and the preceding construction. An area within the crane movable range that is separated from the plane projection area of the zone Ej (j <i) by more than the minimum crane working radius and more than the danger radius is defined as the effective movable range.

JP 2011-65626 A JP 2004-239050 A

  According to the technique described in Patent Document 1, the time required for work and the number of heavy machines are set separately for each type of work. That is, the type of heavy machinery to be used is determined for each type of work. For this reason, in the technique described in Patent Document 1, it is necessary to calculate the work time when using heavy machinery having different rated loads and main body shapes each time. Also, when comparing work times between different heavy machinery, the user needs to compare manually. For this reason, the technique described in Patent Document 1 may reduce the efficiency of planning.

  Moreover, in the technique of patent document 2, as a result, one unit which satisfies the lifting performance and can perform work is selected from the cranes held in the crane database. However, there may be multiple cranes in the crane database that can perform work while satisfying the lifting performance. For example, work can be performed with one selected unit, but the time required for the work can be reduced by using other cranes, and the work can be carried out more safely with a margin between the crane and the building. There is a possibility. That is, in the technique described in Patent Document 2, one heavy machine is selected, but the one may not always be the one that the user desires. For this reason, in order to acquire a crane that can perform the work requested by the user, it is necessary to repeat the selection by updating the contents of the crane database, and it may take a lot of time at the stage of drafting the work plan.

  The present invention has been made in view of such a background, and an object of the present invention is to enable efficient selection of a work tool by a user.

  In order to solve the above-described problems, the present invention is characterized in that a work index is calculated for each of a plurality of work tools that can be operated, and information related to the work tool and the calculated index are displayed in association with each other.

  According to the present invention, it is possible to enable efficient selection of a work tool by a user.

The site information may store information that is not included in the building information or site information, such as weather conditions in the building or site.
Furthermore, when a plurality of heavy machinery is arranged at the work site, the site information may store information on the position of the heavy machinery. Further, the device information may store information related to the work process (such as a device destination position). Information regarding the work process may be stored in the field information.
As will be described later, the site layout information is generated based on the building information, site information, and site information.

The device information storage unit 44 stores device information having information such as the shape and mass of the target device that is the work target for each target device. The device information will be described later with reference to FIG.

The heavy equipment selection support screen will be described later.

[Heavy equipment information]
FIG. 2 is a diagram illustrating an example of heavy equipment information when the heavy equipment is a crane.
As shown in FIG. 2, the heavy equipment information includes “heavy equipment name”, “rated load”, “working radius”, “turning angle”, “operation speed”, and “shape” for each heavy equipment. The rated load describes the work radius possible for each maximum mass, and the operating speed includes the operating speed when the boom moves up and down (the up-and-down speed) and the boom operates in the left-right direction. The operation speed (turning speed) at the time of turning is described. Although not shown in FIG. 2, the “shape” describes the size of each component. Heavy equipment usage fee information, which is a usage fee for heavy equipment, may be included in the heavy equipment information. In the present embodiment, information on one heavy machine in the heavy machine information is referred to as a heavy machine record.

Here, the working radius is the maximum value of the distance in the horizontal direction from the rotation center position of the boom to the position of the wire that suspends the target device. The working radius is limited by the mass of the target device to be suspended, and the maximum mass that can be suspended with a certain working radius is stored in the heavy equipment information.
For example, when the working radius is 6 m, the heavy equipment “C1” can suspend a target device having a mass of 50 t at the maximum. In addition, the heavy machine “C1” can change the working radius in a range from 1 m to 6 m when, for example, a target device having a mass of 50 t is suspended. On the other hand, when this heavy machine is suspending a target device having a mass of 40 t, it is impossible to work with a working radius exceeding 7 m.

[Equipment information]
FIG. 3 is a diagram illustrating an example of device information.
As illustrated in FIG. 3, the device information includes information on “width”, “depth”, and “height” in “device name”, “mass”, and “included rectangular parallelepiped”. Here, the inclusion cuboid is a cuboid circumscribing the target device, and the target device is completely contained in the inclusion cuboid.
In FIG. 3, only the information on “condenser” is described, but information on a plurality of devices is actually described. In the present embodiment, information on one device among the device information is referred to as a device record. In the device information, it is desirable that device records are stored in the order of processes.

[Processing procedure]
FIG. 4 is a flowchart showing a processing procedure in the heavy machinery support apparatus according to the first embodiment. Hereinafter, the building information is stored in the building information storage unit 41, and the site information is stored in the site information storage unit 42. Similarly, the site information is stored in the site information storage unit 43, the device information is stored in the device information storage unit 44, and the heavy machinery information is stored in the heavy machinery information storage unit 45. In the present embodiment, description of the storage source of each information is omitted.

  First, the layout information generating unit 13 integrates building information, site information, site information, and the like, and generates site layout information that is layout information at a site where work is performed on heavy machinery (S101). The site layout information stores information related to the layout of the building, and information related to undulations in the building and the site and information related to the site installation.

FIG. 5 is a schematic diagram illustrating an example of each piece of information stored in the site layout information.
In the example of FIG. 5, the building 501 held by the building information, the site 502 stored in the site information, the heavy equipment work area 503 and the temporary storage area 504, and the site installation object 505 stored in the site information are shown. An integrated field layout is shown. Here, the field installation object 505 is, for example, rubble, scaffolding, water injection hose, or the like existing on the site 502. When a target device (not shown in FIG. 5) is moved using a heavy machine (not shown in FIG. 5), the heavy machine can be operated only on the heavy machine work area 503 in the site 502. it can. In addition, when the target device is not moved by the heavy machinery, the target device exists on the building 501 or the temporary storage area 504. Here, it is necessary for the heavy machinery to operate so as to avoid interference with the field installation object 505 existing at the work site.
Reference numeral 511 denotes a hole in the building 501, and reference numeral 512 denotes radiation emitted from the nuclear reactor in the building 501. The size of the hole 511 and the amount of radiation 512 (radiation dose) are stored in the field information.

Returning to FIG.
Next, the heavy equipment information acquisition unit 12 acquires one heavy equipment record from the heavy equipment information (S102).
Then, the device information acquisition unit 11 acquires one device record from the device information (S103). At this time, the device information acquisition unit 11 acquires information about the position of the movement source of the target device and the position of the movement destination from the building information.
At this time, whether all the device records in the device information are to be processed or whether some device records are to be processed may be set in advance via the input unit 20. In addition, when a part of device records is to be processed, which device record is to be processed or which condition satisfies a device record is set via the input unit 20. May be.

Then, the work availability determination unit 14 performs work by the heavy equipment that is the processing target based on the on-site layout information generated in step S101, the heavy equipment record obtained in step S102, and the equipment record obtained in step S103. It is determined whether or not it is possible (S104).
The movement of the target device includes a case of moving from the temporary placement area 504 in FIG. 5 to the building 501 and a case of movement from the building 501 to the temporary placement area 504. When distinguishing both, the former may be carried in and the latter may be carried out.
In step S104, two determinations are mainly made. The first is a determination as to whether or not the heavy equipment can lift the target device, and the second is a determination as to whether or not interference by the target device occurs during the work by the heavy machinery.

First, the determination of whether or not the heavy equipment can lift the target device will be described in detail.
The heavy machinery moves the target device by winding up or down the attached wire, raising or lowering the boom, or turning the cabin. In step S104, the work availability determination unit 14 may cause the heavy equipment to lift the target equipment by comparing the rated load of the heavy equipment stored in the heavy equipment record with the mass of the target equipment stored in the equipment record. Determine whether it is possible.

This will be described with reference to FIG.
FIG. 6 is a diagram illustrating an example of a rated load table. The rated load table in FIG. 6 is information included in the heavy equipment information (FIG. 2).
As shown in FIG. 6, the rated load table associates the working radius with the maximum mass of the target device that can be hung by the working radius.
First, the work availability determination unit 14 calculates a work radius (reference numeral 702) necessary for lifting the target device 603 and moving it to a destination position based on the site layout information. Next, the work availability determination unit 14 determines whether it is possible to work with the calculated work radius based on the rated load table and the mass of the control device 603 stored in the device record (device information). judge.

  For example, it is assumed that “C1” in FIG. 2 is selected in step S202 as the heavy machine, and “condenser” in FIG. 3 is selected as the target device 603. It is assumed that the distance is 2 m calculated from the on-site layout information. Referring to FIG. 2, the maximum mass at the working radius “2 m” of the heavy machine “C1” is “90 t” and does not exceed the mass “80 t” (FIG. 3) of the “condenser”. 14 determines that work is possible.

Next, a description will be given of a method for determining whether or not interference with the target device does not occur during work with heavy machinery.
First, the work availability determination unit 14 calculates a work radius (reference numeral 602 in FIG. 6) based on the rated load table (FIG. 6) and the mass of the target device (FIG. 3).
Then, based on the calculated work radius and information on the size of the target device in the device record, the work availability determination unit 14 causes interference between the heavy machinery, the target device, the building, the installed object, and the obstacle. It is determined whether or not. Further, the work availability determination unit 14 determines whether the ground contact portion of the heavy machine exceeds the heavy machine work area 503 (FIG. 5) based on the site layout information and the size of the target device.

7 and 8 are schematic diagrams for explaining a method for determining whether or not interference by the target device occurs.
As shown in FIG. 7, the heavy equipment 701 and the target device 702 exist in the site layout corresponding to the site layout information generated in step S101. Here, the heavy machine 701 is a heavy machine stored in the heavy machine record acquired in step S102, and the control device 702 is a target device stored in the device record acquired in step S103. Note that reference numerals 501 to 505, 511, and 512 denote the same elements as those in FIG.

Here, it is assumed that the heavy equipment 701 moves the target device 702 from the temporary placement area 504 to the building 501. Information regarding the movement destination position of the target device 702 is stored in the field information.
As shown in FIG. 8, the work availability determination unit 14 calculates a distance 802 between the laying object 801 and the target device 702 when the target device 702 is moved using the heavy equipment 701. The laying object 801 is an object installed on the site 502 such as the building 501 and the field installation object 505. Note that the laying object 801 may include an emergency water injection hose.
Similarly, the work availability determination unit 14 also calculates a distance 803 between the target device 702 and the heavy machine 701, a distance 804 between the heavy machine 701 and the laying object 801, and the like. In step S104, the work availability determination unit 14 checks for the occurrence of interference based on these distances 802 to 804 and the like. Specifically, when the target device 702 is moved from the movement source to the movement destination within the range of the work radius and the turning angle in the heavy equipment information (FIG. 2), a negative value among the distances from the installation object 801 is set. By determining whether or not there is a distance, it is determined whether or not interference has occurred.
The use of the size of the hole 511 of the building 501 and the amount of radiation 512 (radiation dose) will be described later.

For example, it is assumed that “C1” in FIG. 2 is selected in step S202 as the heavy machine, and “condenser” in FIG. 3 is selected as the target device 603.
At this time, the work availability determination unit 14 determines whether or not the “condenser” can be moved based on the “contained cuboid” information of the “condenser” and the site layout information. Further, the work availability determination unit 14 calculates the work radius of the heavy machine “C1” based on the rated load of the heavy machine “C1” and the mass of the “condenser”, and sets the work radius calculated by the heavy machine from the site layout information. To determine whether work is possible.

  In this way, by narrowing down the heavy machines on condition that there is interference between the laying object and the heavy machines, the number of heavy machines to be selected can be narrowed down, and work efficiency can be promoted.

Returning to the description of FIG.
As a result of step S104, when the work is possible (S104 → Yes), the index processing unit 15 calculates an index, and adds the calculated index to the index list of the index storage unit 46, whereby the index is stored in the index storage unit 46. (S105). The calculated index will be described later with reference to FIGS.
After the process of step S105 or when it is determined in step S104 that the work is impossible (S104 → No), the device information acquisition unit 11 determines whether or not the processing has been completed for all target devices ( S106).
As a result of step S106, when the processing has not been completed for all target devices (S106 → No), the device information acquisition unit 11 returns the processing to step S103, and acquires a record that has not been acquired from the device information.

As a result of step S106, when the processing has been completed for all target devices (S106 → Yes), the heavy equipment information acquisition unit 12 determines whether the processing has been completed for all heavy equipment (S107).
As a result of step S107, when the processing has not been completed for all the heavy machinery (S107 → No), the heavy machinery information acquisition unit 12 returns the processing to step S102, and acquires a record that has not been acquired from the heavy machinery information.
As a result of step S107, when the processing is completed for all the heavy machines (S107 → Yes), the display processing unit 16 outputs a heavy machine selection support screen in which the heavy machines are arranged based on each index calculated in step 105. 30 (S108), and the process ends.

[Example of index and heavy equipment selection support screen]
(When working time is used as an indicator)
FIG. 9 is a diagram showing an example of a heavy machinery selection support screen when the index is the work time.
The display processing unit 16 rearranges the names of the heavy equipment based on the index based on the index calculated and stored in step S105, and displays the result on the output unit 30 as the heavy machine selection support screen 100a.
In the example shown in FIG. 9, the names of heavy machines are arranged on the axis of work time as an index according to the work time of each heavy machine. The work time is the time that the index processing unit 15 takes for each heavy machine to perform work. The work time is obtained by adding the movement speed of each part to the movement amount of each part of the heavy machine such as the boom and wire of the heavy machine that operates when performing the work, and calculating the sum of the results. For example, the index processing unit 15 calculates the work time based on the “undulation speed” and the “turning speed” in the “operation speed” of FIG.

  In the example shown in FIG. 9, display is performed for five heavy machines “C1”, “C2”, “C3”, “C4”, and “C5”. The heavy machines displayed in FIGS. 9, 10, 11, and 17 to 19 are only heavy machines determined as “Yes” in step S104 of FIG. That is, the five heavy machines displayed on the heavy machine selection support screens 100a to 100f in FIGS. 9, 10, 11, and 17 to 19 are not affected by interference or interference with respect to all target devices acquired by the device information acquisition unit 11. It is a heavy machine that can perform work without causing excess. Here, the work time is an average of work times for all target devices.

The display processing unit 16 is not limited to displaying only heavy equipment that can perform work without causing interference or excess for all target devices, but also for specific target devices. You may display the heavy machine which does not generate | occur | produce. In this case, the work time is an average of work times for the target device that is the processing target.
In addition, in FIGS. 9, 10, 11, and 17 to 19, the name of the heavy machine is arranged for the index, but the type of heavy machine may be arranged. In this case, the heavy equipment information is stored for each type of heavy equipment.

  In the example shown in FIG. 9, the work time by the heavy machine “C1” is the shortest. Based on this result, the user selects the type of heavy machine to be assigned in the work plan.

In this way, by placing the names of all heavy equipment that can perform work on the axis of the index, it becomes possible to compare heavy equipment, and further, the range of selection by the user can be expanded, and the efficiency by the user can be increased. It becomes possible to select a typical work machine (work tool). In other words, the display processing unit 16 displays the index for each heavy machine so that the user can compare, so that the heavy machine can be selected efficiently by the user, and as a result, the work planning can be made more efficient. .
Furthermore, according to the present embodiment, since the index held by each of the plurality of heavy machinery is calculated based on the situation at the work site, it is possible to prevent reworking of work planning due to unconfirmed index by the user. .
In addition, by arranging the names of heavy machines on the axis indicating the index, the user can easily recognize the index relationship of each heavy machine.
Further, by using the work time as an index, the user can select a heavy machine in consideration of a delivery date and the like.

(When index is working distance)
FIG. 10 is a diagram illustrating an example of a heavy machine selection support screen when the index is a work distance.
FIG. 10 is a heavy machinery selection support screen when the index is the shortest work distance (hereinafter referred to as the shortest work distance).
As shown in FIG. 10, heavy machinery “C1”, “C2”, “C3”, “C4”, and “C5” are displayed on the axis of the shortest work distance as an index on the heavy machinery selection support screen 100b. Arranged according to the shortest working distance.

  Here, the shortest work distance is the shortest distance among the distances (distances 802 to 804) between the building 501, the field installation object 505, the target device 602, and the heavy machinery 601 calculated in FIG. Note that the shortest work distance includes the minimum distance between the hole 511 (FIG. 7) opened in the building 501 and the heavy machine 601 and the minimum distance between the water injection hose and the heavy machine 601.

  Further, the index processing unit 15 uses the shortest distance between objects from the start to the end of the work as an index based on the distances 802 to 804 calculated by the work availability determination unit 14 in step S105 of FIG. Calculate for each heavy machine. Here, when carrying in, it is possible not to calculate the shortest work distance in the procedure of finally winding down the wire and installing the target device 602 in the building 501. Similarly, when carrying out, it is possible not to calculate the shortest work distance in the procedure of first winding the wire and lifting the target device 602 from the building 501.

In step S108 of FIG. 4, the display processing unit 16 aggregates the shortest work distances, rearranges the heavy machinery based on the index, and displays the result on the output unit 30 as a heavy machinery selection support screen 100b shown in FIG.
The user selects heavy equipment to be assigned in the work plan based on the display screen. In the example illustrated in FIG. 10, the shortest distance in the work of the heavy machine “C1” is the shortest compared to other heavy machines. As a result, when the heavy machinery “C1” is selected, it is possible to avoid situations where the heavy machinery is far away from the target device or the work is carried out in a place far from the building. Efficient work can be expected with reduced physical occupancy.
Further, when the user determines that the work distance is too short for the heavy machine “C1”, the user can select the heavy machine “C3” having a larger work distance than the heavy machine “C1”.

  In this way, by setting the index to “the shortest work distance”, the user can select a heavy machine considering the state of the work site.

(When the indicator is a usage fee)
FIG. 11 is a diagram illustrating an example of a heavy machine selection support screen when the index is a heavy machine usage fee, and FIG. 12 is a diagram illustrating an example of usage fee table information.
Heavy machinery used for work may be rented in addition to those held by the company. In such a case, charging is required when using heavy machinery in various forms. Here, such billing is called a heavy machine usage fee.
When the index is a heavy machine usage fee, first, the index processing unit 15 calculates the working time using the same method as in FIG. 9 in step S105 in FIG. Then, the index processing unit 15 calculates the usage fee for the heavy equipment to be processed based on the calculated work time and the usage fee information shown in FIG. 12 and records it in the index storage unit 46.
As shown in FIG. 12, the usage fee information stores a usage fee for each time unit for each heavy machine.

  Here, the working time of heavy equipment “C1” is 1.5 hours, the working time of heavy equipment “C2” is 2.4 hours, the working time of heavy equipment “C3” is 3.3 hours, and the working time of heavy equipment “C4”. Assume that the working time of heavy equipment “C5” is 4.6 hours for 4.2 hours. Assuming that the usage fee is charged on an hourly basis, a 2-hour usage fee (19000 yen) is applied to the heavy equipment “C1” based on the usage fee information shown in FIG. Similarly, a usage fee of 3 hours (14,000 yen) is applied to the heavy equipment “C2”, and a usage fee of 4 hours (46000 yen) is applied to the heavy equipment “C3”. Furthermore, the heavy equipment “C4” is applied with a usage fee of 5 hours (¥ 29000), and the heavy equipment “C5” is applied with a usage fee of 5 hours (¥ 51000).

Then, the display processing unit 16 arranges each heavy machine “C1” to “C5” on the axis of the usage fee as an index according to the usage fee, thereby outputting the heavy machine selection support screen 100c shown in FIG. 30.
From FIG. 11, it can be seen that the usage fee of the heavy equipment “C1” is the cheapest. The user selects a heavy machine with reference to the heavy machine selection support screen 100c of FIG. When the usage charges of a plurality of heavy machines are the same, the user may select heavy machines with reference to the heavy machine selection support screens 100a and 100b shown in FIG. 9 and FIG.
Thus, by setting the “use fee” as the index, the user can select heavy equipment in consideration of the budget and the like.

The transportation cost may be used instead of the usage fee. By doing in this way, the user can select heavy machinery in consideration of transportation costs.
In addition, as an index, access to the hole 511 (FIG. 7) of the building 501; location restriction due to debris; arrangement of emergency water injection hose; amount of radiation 512 (FIG. 7) emitted from the building (radiation dose) are used. May be. For example, when using access to the hole 511 of the building 501 as an index, the specific index is the shortest working distance between the hole 511 of the building 501 and the heavy machinery. In addition, when using place restrictions due to rubble as an index, the specific index is the shortest working distance between rubble and heavy equipment. And when using arrangement | positioning of the emergency water injection hose as a parameter | index, a concrete parameter | index becomes the shortest work distance of an emergency water injection hose and a heavy machine. Furthermore, when a radiation dose is used as an index, a specific index is a radiation transmission amount or the like. For example, the user can select an appropriate protective clothing by using the amount of radiation transmitted through the protective clothing as an index. In addition, the value regarding the movable condition of a heavy machine can be used as an index. In this way, the user can select heavy machinery in consideration of the state of the work site.

<< Second Embodiment >>
Next, a second embodiment according to the present invention will be described with reference to FIGS.
The second embodiment is characterized by narrowing down usable heavy machinery using a predetermined condition.

[Device configuration]
FIG. 13 is a functional block diagram illustrating a configuration example of the heavy machinery work support device according to the second embodiment.
In FIG. 13, the same components as those in FIG.
The heavy machinery work support device 1a in FIG. 13 differs from the heavy machinery work support device 1 in FIG. 1 in that it has a weather condition storage unit 47 in which weather condition information describing work restrictions on weather conditions such as wind speed is stored. This is the point. The work restrictions will be described later.
In addition, the index processing unit 15a in the processing unit 10a refers to the weather condition information that is a predetermined condition stored in the weather condition storage unit 47, and narrows down the heavy equipment that can be operated in FIG. It is different from the processing unit 15.

[Processing procedure]
FIG. 14 is a flowchart showing a processing procedure of the heavy machinery work support apparatus according to the second embodiment.
In the process of FIG. 14, the same processes as those in FIG. 4 are denoted by the same reference numerals and description thereof is omitted.
First, a narrowing condition is set by inputting information such as whether or not to narrow down in weather conditions and how much narrowing is to be performed when narrowing down via the input unit 20 (S201). . The process of step S201 will be described later with reference to FIG.
In step S107, when the processing is completed for all the heavy machinery (S107 → Yes), the index processing unit 15a works based on the narrowing-down conditions set in step S201 and the weather condition information in the weather condition storage unit 47. A narrowing process for narrowing down the possible heavy machines is performed (S202). Subsequently, the display processing unit 16 performs the process of step S108 based on the narrowing-down result.
In this embodiment, the process of step S202 is performed after step S107. However, the present invention is not limited to this, and immediately after the calculation of the index in step S105, the heavy machine whose index is calculated corresponds to the condition of the weather condition information. The index processing unit 15a may determine whether or not a heavy machine that does not satisfy the condition may be deleted.

(When the predetermined condition is wind speed)
Hereinafter, the case where the predetermined condition is the wind speed will be described with reference to FIGS.
FIG. 15 is a diagram illustrating an example of a weather condition setting dialog.
As described above, in step S201 in FIG. 14, weather conditions for performing work are input via the input unit 20. At this time, a weather condition setting dialog as shown in FIG. 15 is displayed on the output unit 30 to prompt the user to input the weather condition setting. In FIG. 15, three weather conditions that can be set are “not considering weather conditions”, “less than maximum wind speed 4 m / s”, and “greater than maximum wind speed 4 m / s”. The conditions are not limited to these.

FIG. 16 is a diagram showing weather condition information.
As shown in FIG. 16, the weather condition information stored in the weather condition storage unit 47 includes the weather condition specified by the user (here, wind speed) and the work restriction (here, distance restriction) for this weather condition. A combination is described.
For example, when the maximum wind speed during the work period is 4 m / s or more, the shortest work distance described in FIG. 10 needs to be 2 m or more. Similarly, when the maximum wind speed during the work period is less than 4 m / s, the work shortest distance needs to be 1 m or more. In addition, there is no distance limitation when weather conditions are not applied.

The index processing unit 15a narrows down heavy machinery based on the weather conditions input and set in step S201 in step S202 in FIG. 14, the weather condition information in FIG. 16, and the on-site weather conditions stored in the on-site information. Do.
When the work shortest distance is calculated as shown in FIG. 9 and a wind speed of 4 m / s or more is set and input as a weather condition, a heavy machinery selection support screen 100d shown in FIG. That is, among the heavy machines “C1” to “C5” in FIG. 9, the displays of the heavy machines “C1” to “C3” whose work shortest distance is 2 m or less are deleted, and the heavy machines “C4” and “C4” whose work shortest distance is 2 m or more are deleted. “C5” is displayed.

FIG. 17 is a diagram illustrating an example of a heavy machinery selection support screen in consideration of weather conditions.
From the heavy equipment selection support screen 100d shown in FIG. 17, it can be seen that the heavy equipment “C1” to “C3” having the shortest distance of less than 2 m cannot be performed due to the weather conditions. That is, it can be seen that the heavy machines capable of performing the work are “C4” and “C5”.
The user selects a heavy machine to be assigned in the work plan based on such a display screen. Incidentally, in the example of FIG. 17, the shortest work distance in the heavy machine “C5” is smaller than that in the heavy machine “C4”.
According to the second embodiment, by selecting only heavy equipment that satisfies a certain clearance (work restriction) with respect to a predetermined condition, it is possible to select heavy equipment that meets different safety conditions at each site. .
In other words, the user can select heavy machinery in consideration of weather conditions such as wind fluctuation.
In addition to wind speed, precipitation, temperature, etc. may be used as weather conditions.

<< Third Embodiment >>
Up to now, the index is displayed as a one-dimensional axis, and the name of the heavy equipment is arranged on the axis. However, the coordinates are displayed by displaying the axes of two or more indices, and the heavy equipment is displayed on the coordinates. You may make it arrange | position a name.
The heavy machinery work support apparatus according to the third embodiment has the same configuration as the heavy machinery work support device 1 shown in FIG.
Further, the processing procedure of the heavy machinery work support apparatus according to the third embodiment is that the output unit 30 calculates a plurality of indexes in step S105 of FIG. 4 and outputs a heavy machinery selection support screen using each index as a coordinate axis in step S108. Since the display is the same as FIG. 4 except for and displayed in FIG.

FIG. 18 is a diagram illustrating an example of a heavy machine selection support screen in which names of heavy machines are arranged on three-dimensional coordinates with the work time, the shortest work distance, and the usage fee as coordinate axes.
Here, the work time, the work shortest distance, and the usage fee are calculated by the method described with reference to FIGS. 9, 10, and 11. That is, in step S105 of FIG. 4, the index processing unit 15 calculates three indexes of work time, work shortest distance, and usage fee.
The display processing unit 16 displays the heavy machine selection support screen 100e on the output unit 30 by arranging the name of each heavy machine with the index value as the coordinate value in the three-dimensional coordinates as shown in FIG. The user refers to the heavy equipment selection support screen 100e and selects heavy equipment to be used for work.
The indices used in the heavy equipment selection support screen 100e as shown in FIG. 18 are not limited to the work time, the work shortest distance, and the usage fee.

FIG. 19 is a diagram illustrating an example in which names of heavy machinery are arranged on two-dimensional coordinates with the work time and the shortest work distance as coordinate axes.
As shown in FIG. 19, the name of a heavy machine may be arranged on a two-dimensional coordinate having two indices as coordinate axes.
Here, the work time and the work shortest distance are calculated by the method described with reference to FIGS.
The display processing unit 16 displays the heavy machine selection support screen 100f on the output unit 30 by arranging the name of each heavy machine in the two-dimensional coordinates as shown in FIG. That is, in step S105 in FIG. 4, the index processing unit 15 calculates two indices of work time and work shortest distance.
The user refers to the heavy equipment selection support screen 100f and selects heavy equipment to be used for work.
In FIG. 19, the work time and the shortest work distance are used as coordinate axes. However, any two of the work time, the shortest work distance, and the use time may be used as coordinate axes. Alternatively, indices other than the work time, the work shortest distance, and the use time may be used.

  Thus, by displaying a plurality of indices together, the user can compare the indices simultaneously, and can select heavy machinery based on a plurality of conditions.

  Note that, by deleting specific coordinates from the three coordinate axes in FIG. 18, the heavy machinery selection support screen 100e (FIG. 18) using the three-dimensional coordinates becomes the heavy machinery selection support screen 100f (FIG. 19) using the dimensional coordinates. You may make it change to. For example, the coordinate axis of the usage fee may be deleted by selecting the coordinate axis of the usage fee from the three coordinate axes in FIG. As a result, the heavy equipment selection support screen 100e (FIG. 18) is changed to the heavy equipment selection support screen 100f (FIG. 19).

In addition, a heavy machine selection support screen 100f (FIG. 19) displays two coordinate axes by inputting a coordinate name in a coordinate addition input window (not shown) or the like to the heavy machine selection support screen 100f (FIG. 19) having two coordinate axes. It may be changed to the heavy equipment selection support screen 100e (FIG. 18). For example, by inputting “usage fee” to a coordinate addition input window (not shown) via the input unit 20, the display processing unit 16 adds heavy machinery selection support in which the coordinate axis of the usage fee is added to the heavy machinery selection support screen 100f (FIG. 19). You may make it change into the screen 100e (FIG. 18).
In the same way, the display processing unit 16 displays a heavy machine selection support screen with one index axis as shown in FIGS. 9, 10, and 11, and a heavy machine having a plurality of coordinate axes as shown in FIGS. 19 and 18. You may make it change to selection assistance screen 100e, 100f.

Further, in FIGS. 18 and 19, the indices are three indices and the two indices are coordinate axes, respectively, but four or more indices may be used. In this case, the fourth and subsequent indices may be expressed by colors or the like.
The heavy machinery selection support screens 100e and 100f shown in FIGS. 18 and 19 may be redisplayed by changing the viewpoint position, the enlargement ratio, and the like by operating the input unit 101.
Further, the display processing unit 16 may narrow down heavy machines on the heavy machine selection support screens 100e and 100f shown in FIGS. 18 and 19 according to predetermined conditions (such as weather conditions) as in the second embodiment. Good.

  In the present embodiment, it is assumed that a heavy machine such as a crane is used for plant construction or removal. However, the present invention is not limited to this, and the present invention may be applied to a work such as a forklift in a warehouse. Alternatively, work tools such as protective clothing, magic hands, and robots may be applied instead of heavy machinery. In this case, the mobility of the protective clothing, the amount of transmitted radiation, the mobility of the magic hand, the reach distance, the work time of the robot, the shortest work distance, the use time, and the like may be used as indices.

In addition, although the present embodiment is intended for a nuclear power plant, it can be used for selecting a thermal power plant, a petrochemical plant, and heavy machinery at a disaster site.
