  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram for explaining the caisson filling material input management system according to the present embodiment. FIG. 2 is a block diagram schematically showing the caisson filling material input management system of FIG. 1 mounted on two gut ships.

  As shown in FIG. 1, when a relatively large caisson KS having a plurality of compartments R is installed on the bottom ground G for revetment and quay construction, etc. The filling material is introduced using a gut ship GT or the like. 1 is a self-propelled stone carrier ship having a grab lifting device, and as a charging means for filling materials, etc., a boom BM that can be swung / expanded and a closing part that is suspended from its tip and can be opened and closed. And grab GB. Filled sand that has been transported by controlling the expansion and contraction and turning of the boom BM and the opening and closing of the grab GB by maneuvering in the operator room OP of the gut ship GT is thrown into the compartment R of the caisson KS. In addition, the foundation mound may be constructed | assembled previously by the rubble etc. for the water bottom ground G in which the caisson KS is installed.

  The caisson filling material input management system 10 shown in FIG. 1 is used when the filling sand transported by the gut ship GT is thrown into the compartment R of the caisson KS by the operation of the boom BM and the grab GB. The input information such as the number of times is managed, and the operator room OP is instructed of an appropriate compartment R into which the filling sand is to be input.

  As shown in FIG. 2, the caisson filling material input management system 10 in FIG. 1 is a personal computer (personal computer, PC) as information processing means for inputting various information, performing predetermined information processing, and storing the filling information of filling sand and the like. PC) 11, a display unit 12 comprising a liquid crystal display monitor for displaying various information, a wireless LAN 13 for performing information communication via a wireless antenna 13a in order to share input information and the like with another gut ship, A GPS main body 14, a GPS receiving unit 15 including a GPS antenna and provided at the tip of the boom BM, the upper center of the grab GB, and the like, and a grab opening / closing sensor 16 for detecting the opening / closing of the grab GB are provided.

  The grab opening / closing sensor 16 may be configured to detect actual opening / closing of the grab GB, or configured to detect feeding of the grab opening / closing wire, but is not limited thereto.

  FIG. 2 also shows another caisson filling material input management system 10A mounted on another gut ship. Like the caisson filling material input management system 10, a personal computer (PC, PC) 21 and display A unit 22, a wireless LAN 23, a GPS main body 24, a GPS receiving unit 25, and a grab open / close sensor 26 are provided.

  FIG. 3 is a plan view schematically showing a plurality of compartments of the caisson and the positions of two gut ships in contact with the caisson in the present embodiment. 4 is a block diagram showing a schematic configuration of the personal computers (PCs) 11 and 21 of the caisson filling material input management systems 10 and 10A of FIG.

  As shown in FIG. 3, for example, when filling sand is introduced into a relatively large caisson KS having 30 compartments of 6 rows (A to F) × 5 rows (1 to 5), 2 Two gut ships GT1 and GT2 are used. The booms BM1 and BM2 of the gut ships GT1 and GT2 turn around the rotation centers r1 and r2 of the crane, and the filled sand is thrown into the compartment from the grab GB (FIG. 1) suspended from its tip at a predetermined position. However, due to boom length, etc., there is a case where one gut ship GT1 cannot be put into all the compartments of caisson KS. For example, filled sand is thrown into the compartments up to the broken line a in FIG. Is possible. Similarly, a range in which medium-filled sand can be input is set for the gut ship GT2.

  As shown in FIG. 4, the PC 11 of the caisson filling material management system 10 shown in FIGS. 1 and 2 is used for inputting / outputting various information by a central processing unit (CPU) 31 that executes various controls and a wireless LAN 13 or the like. Interface unit (I / F) 32, an input unit 33 including a pointing device such as a mouse for inputting information and a keyboard, a storage unit 34 including a ROM and a RAM for storing various information, a hard disk and a ROM And a software storage unit 35 that stores software such as an OS (operating system) 35a and caisson filling material input management software 35b, and temporarily stores programs and various information during control. And a memory 36 composed of a RAM or the like.

  The storage unit 34 in FIG. 4 stores the position information of each compartment of the caisson within the range in which one gut ship can be entered as shown by the broken line a in FIG. 3, the plane coordinates of each compartment of the caisson, and the entry information. Various information such as the number of times of filling of the filling material and the amount of filling material in each compartment of the caisson is stored.

  As shown in FIG. 1 to FIG. 4, the two gut ships are connected to each storage unit of the PCs 11 and 21 by connecting the PCs 11 and 21 wirelessly with each other via the wireless LANs 13 and 23 as indicated by broken lines in FIG. Various information such as the same input information can be stored, and input information can be shared.

  Further, the GPS receivers 15 and 25 and the GPS main bodies 14 and 24 obtain the plane coordinate information of the grab GB from the received GPS position information, and the plane coordinate information of the grab GB and the caisson KS stored in the storage unit 34. The plane position of the grab GB with respect to the compartment R of the caisson KS of the compartment R can be determined.

  When grab GB is opened and filled sand is inserted, grab opening / closing sensor 16 detects the loading of the filled material, thereby detecting that it has been inserted into compartment R of caisson KS corresponding to the planar position of grab GB. Then, one filling of the filling material is counted and stored in the storage unit 34 for the compartment R into which the filling sand is placed. In this manner, the number of times of filling of the filling material is stored in the storage unit 34 for each compartment of the caisson KS every time filling sand is inserted.

  Even if the grab GB moves to the sand storage part of the gut ship GT by the turning of the boom BM and opens to grab the filled sand at that position, the compartment of the caisson KS corresponding to the planar position of the grab GB Since there is no medium, the filling material is not counted. Further, since the capacity of the grab GB (the volume in which the grab GB holds the filled sand) is known, the accumulated amount of filled medium can be calculated from the number of filled medium charges.

  FIG. 5 is a diagram showing an example of the filling material input management screen displayed on the display unit of FIGS. 1 and 2.

  As shown in FIG. 5, a plan view of a plurality of compartments of the caisson is displayed on the display units 12 and 22 of the PCs 11 and 21 as a filling material input management screen. Displays the number of fillings input. Thereby, it is possible to visually know the number of filling times of the filling material for each compartment of the caisson.

  It is also possible to display the accumulated filling material input amount (the capacity of the grab GB × the number of medium filling materials) as well as the number of filling materials input on the filling material input management screen as shown in FIG. Alternatively, only the accumulated filling material input amount may be displayed. The display of the accumulated filling material input amount is suitable when a plurality of gut ships are used and the glove capacity differs for each gut ship.

  In addition, in order to evenly insert the filling sand into each compartment of the caisson, the personal computers 11 and 21 calculate the difference in the number of filling materials in each compartment, and the difference in the number of fillings is a predetermined value or more. If it is determined, the display unit 12 or 22 selects the compartment with the smallest number of insertions and displays a warning by flicker display or the like as shown by line b in the figure. As a result, the operator in the operator room OP can know that the number of times of filling of the filling material has been varied, and the position of the compartment to be charged next so as not to cause an unbalanced load by the caisson.

  When the difference in the number of times of insertion becomes less than a predetermined value, the warning display by flicker display stops. Further, the compartments displayed on the screen may be color-coded according to the number of times of charging, and the number of times of filling of the filling material may be displayed by color together with the numerical value display.

  Further, the PCs 11 and 21 select the recommended filling position for filling the middle sand in consideration of the eccentric load in the caisson, and display the marking as indicated by a broken line c in FIG. Further, as shown in FIG. 5, the operator can grasp the current position of the boom BM by displaying the tip position of the boom BM obtained from the GPS position information as indicated by a line d in the figure.

  Further, when a compartment range in which the filling sand can be introduced by each gut ship is set in the caisson as shown in FIG. 3, the PCs 11 and 21 store the compartment range (plane coordinates of the compartment) that can be introduced. 34 is stored. When the recommended filling position of the filling sand is selected by the marking as shown by the broken line c in FIG. 5, if the gut ship is out of the possible input range, the display part of the gut ship shows the broken line c in FIG. 5. Such markings are not displayed, but are displayed on the display unit of the gut ship that is within the possible input range.

  The caisson filling material input management software 35b of the software storage unit 35 of the PC 11 in FIG. 4 stores and stores a program for caisson filling material input management, and this program is executed under the control of the CPU 31. Thus, the PC 11 can execute each step in FIGS. 6, 7, 9, and the like. The PC 21 is configured in the same manner as in FIG.

<First operation>
A first operation by the caisson filling material input management systems 10 and 10A of FIGS. 1 to 5 will be described with reference to FIG. FIG. 6 is a flowchart for explaining each step (S01 to S14) by the first operation by the caisson filling material input management system of FIGS.

  First, as a preset, as shown in FIG. 1, the GPS receiver 15 is installed at the tip of the boom BM of the gut ship GT to be used, and the PC 11 and the GPS main body 14 are installed in the operator room OP. When another gut ship is used, the GPS receiver 25, the PC 21, the GPS main body 24, etc. in FIG. 2 are installed in the same manner. Launch the caisson filling material input management program installed in the caisson filling material management software 35b of the software storage unit 35 of the PC 11, 21 and input the data of the coordinates of the caisson and the boom length to the personal computers 11 and 21. And stored in the storage unit 34 (S01).

  As shown in FIG. 3, the gut ship GT1 is brought into contact with the caisson KS to position the gut ship GT1. At this time, the personal computer 11 displays on the screen of the display section 12 a possible range such as the broken line a in FIG. 3 calculated from the boom length. The throwable range is determined by the boom length, and the plane coordinates of each compartment are recognized using the crane rotation centers r1 and r2 as the origin, and stored in the storage unit 34.

  Next, a screen asking whether or not the work is a new work is displayed on the display unit 12 of the PC 11 (S03). If it is a new work, a “new” button is pressed on the screen, and if it is not a new work, the previous data is updated (S04).

  Next, a screen asking whether the gut boat to be used is single or two ("single or two boats" is displayed, and either "single" or "two boats" is selected on the screen (S05 ).

  When two gut ships are used, the PCs 11 and 21 are wirelessly connected via the wireless LANs 13 and 23, and the filling data of the filling sand is shared (S06).

  Next, the “loading start” button displayed on the screen of the display unit 12 of the PC 11 of the gut ship is pushed (S07). Thereby, the filling material input management screen 41 as shown in FIG. 5 is displayed on the display unit 12 of the PC 11.

  The gut ship carries the filled sand, steers the boom BM and the grab GB, and performs the filled sand input operation into the compartment of the caisson KS (S08). The filling material input management screen 41 of the display unit 12 in FIG. 5 displays the number of times of filling of the filling material for each compartment of the caisson. That is, when the filling sand is thrown in, the grab opening / closing sensor 16 detects the throwing, and 1 is added to the compartment specified to be thrown based on the plane coordinates of the grab GB obtained from the GPS position information. Displays the number of times of filling sand filling.

  In the filling material input management screen 41 in FIG. 5, the tip position of the boom BM is displayed as a line d. At this time, since the number of fillings of the filling sand is small, a flicker display like the line b is displayed. The boom BM can be moved to the position of the compartment and the filling material can be charged. In this way, by displaying warnings such as flicker display, the operator can be notified of the compartment with a small number of times of introduction, the boom BM can be guided to the compartment, and the caisson KS can be charged so that there is no unbalanced load. .

  Even when the flicker is not displayed, the operator can input the filled sand into the compartment at the recommended position by displaying the recommended loading position in consideration of the unbalanced load in the caisson KS by the marking line c in FIG. It can be carried out.

  Next, when the filling sand filling operation by the gut ship is completed, a screen asking whether "the gut ship filling sand is exhausted or a prescribed amount has been entered" is displayed on the display unit 12 (S09). If you have not reached the specified amount yet and select “No padded sand”, you will be asked whether you want to use one or two gut ships (single or two ships). In the above, either “single” or “two vessels” is selected (S10), and when the specified amount of filled sand enters each compartment of the caisson, the operation ends (S14).

  When a single gut ship is selected in step S10, sharing using wireless LAN connection is canceled in step S06 (S11).

  Next, the display unit 12 displays a screen asking about “completion or continuation” of the loading operation (S12). When “continuation” of the loading operation is selected, the gut ship carries the filling sand ( S13), the process returns to step S02, and the same procedure is repeated thereafter. If the input operation is completed, the user completes the operation by pressing the “complete” button displayed on the display unit 12 (S14).

  As described above, according to the caisson filling material input management system of the present embodiment, the plane coordinates of the glove of the gut ship that inputs the filling sand are obtained from the GPS, and the plane coordinates of the grabs and the plane of each compartment are obtained. When the grab opening / closing sensor 16 detects the loading of the filling material from the coordinates, the filled compartment is identified, the loading is counted once, and the number of filling materials is automatically accumulated and stored.

  Conventionally, the number of filling materials and the number of filled compartments have been checked by the operator's memory and visual inspection. However, in the case of a large caisson, the filling compartment is filled by two gut ships, so it is necessary to grasp the filling compartment. However, according to this embodiment, when filling sand filling work with two gut ships, both PCs 11 and 21 are wirelessly connected. In addition, data on the number of filling materials in each compartment of the caisson is shared and stored, and the filling number of filling materials in the entire caisson is displayed on the display unit, so that the filling material in each compartment of the caisson can be loaded. Can be managed accurately and centrally.

  If the number of filling materials varies for each compartment of the caisson, a warning display or marking is displayed on the display section of the PC with a small number of loadings and a large difference in the number of loadings. By marking and warning display, it is possible to easily know the next chamber to be introduced, and to manage the caisson so as not to generate an unbalanced load, thereby preventing the caisson from being tilted.

<Second operation>
A second operation by the caisson filling material introduction management system 10, 10 </ b> A of FIGS. 1 to 5 will be described with reference to FIGS. 7 to 10.

  FIG. 7 is a flowchart for explaining each step (S21 to S32) in the second operation by the caisson filling material input management system of FIGS. FIG. 8 is a diagram (a) to (l) for explaining the order (1) to (12) in which the filling sand is put into each compartment of the caisson in the operation according to FIG.

  In the second operation, for caissons having a plurality of compartments, the filling order of the filling sand compartments is determined according to a predetermined rule, displayed on the display unit, and filled by the operator according to the order displayed on the display unit. By performing the sand loading operation, the loading operation is simplified. In this case, the filling operation of the filling sand into each compartment of the caisson can be performed by the first operation of FIG.

  Here, selection of the compartment which becomes the object of the filling sand filling will be described. The selection of the compartment in this embodiment corresponds to one of the following cases 1 to 4. In addition, the first input is performed in an arbitrarily selected compartment.

Case 1 (CASE1): Right compartment 2 of the previously entered compartment Case 2 (CASE2): Compartment case 3 in the diagonal position of the previously entered compartment (CASE3): Left compartment of the previously entered compartment Chamber Case 4 (CASE4): A compartment selected by the “clockwise operation formula” shown in FIG.

  The second operation will be described with reference to FIG. 7. First, as a preset, the number of caisson compartments, the size of the caisson, and the prescribed number of times of input are input to the PC 11 and stored in the storage unit 34 (S21).

  In this example, the number of caisson compartments is 12 in total in 3 rows and 4 rows as shown in FIG. 8, but this is only an example, and other compartment configurations may be used. In addition, the specified number of times of charging is the total number of times of filling of the filled sand calculated from the volume in which a predetermined amount of filled sand is charged in each compartment of the caisson and the volume in which the grab holds the filled sand. If the number of times of charging reaches the specified number of times of charging, it is determined that the charging of the filling sand into the compartment has been completed. In addition, you may make it judge not with the frequency | count of injection | throwing-in but with the input amount of filling sand.

  Next, the filling sand is put into a compartment at an arbitrary position of the caisson (S22). For example, it is a compartment shown by (1) in FIG.

  Next, with reference to the previous charging position, a compartment at a diagonal position with little eccentricity with respect to the center of gravity of the caisson is selected (S23). Then, it is determined whether or not the compartment at the selected diagonal position has been put in (S24). If the compartment has not been put in, the position of the compartment is displayed on the display unit 12 of the PC 11. In the filling material input management screen such as 5, flicker is displayed as a compartment to be input next (S 29).

  Next, the filled sand is put into the compartment designated by the flicker display (S30). It is a compartment shown by (2) in FIG. This is the case 2.

  Next, it is determined whether or not the filled sand has been introduced once for all the compartments (S31), and since it has not been introduced yet, the process returns to steps S23 and S24. Therefore, it is next determined whether or not there is an empty compartment to the right of the compartment introduced last time (S25). Since this compartment is empty, flickering is displayed for this compartment (S29), and filled sand is put into the compartment (S30). It is a compartment shown by (3) in FIG. This is the case 1.

  Next, when returning to steps S23 and S24, since it has not been put into the compartment at the diagonal position of the previously put compartment, flicker display is given to this compartment (S29), and the filled sand in the compartment is displayed. (S30). This is a compartment indicated by (4) in FIG. Case 2.

  Next, when returning to steps S23, S24, and S25, since the right compartment of the previously introduced compartment has already been filled, there is an empty compartment to the left of the previously filled compartment. (S26). Since this compartment is empty, flickering is displayed for this compartment (S29), and filled sand is put into the compartment (S30). This is a compartment indicated by (5) in FIG. This is the case 3.

  Next, when returning to steps S23 and S24, since it has not been put in the compartment at the diagonal position of the previously put compartment, flicker is displayed for this compartment (S29), and the compartment is filled. Sand is thrown in (S30). This is a compartment indicated by (6) in FIG. Case 2.

  Next, the process returns to steps S23, S24, S25, and S26, but since the left compartment of the previously put compartment has already been introduced, an empty compartment is next selected by the “clockwise arithmetic expression”. (S27). Then, it is determined whether or not the selected compartment is empty (S28). If it is empty, flickering is displayed for this compartment (S29), and the filled sand is put into the compartment (S30). ). This is the compartment indicated by (7) in FIG. This is the case 4.

  Thereafter, in the same manner, the selection of empty compartments by cases 1 to 4, flicker display (S29), and filling of filled sand (S30) are repeated, and as a result, in the order of ( 8) Filling material is put into the compartments of (9), (10), (11) and (12).

  Since it is determined that the filled sand has been introduced once for all the compartments (S31), and then it is determined that the prescribed number of times of injection has not been reached (S32), the process returns to step S22, and so on. Thus, compartment selection, flicker display, and filling of the filling material are performed until the specified number of times of filling is reached (S32).

  As described above, according to the caisson filling material input management method of FIGS. 7 and 8, the charging order of the filling sand is displayed on the display unit of the PC for the plurality of compartments of the caisson, and should be input next. Since the operator is informed by warning display of the compartment by flicker display or the like, the operator's input work becomes easy and the burden on the operator is reduced.

  In addition, since the filling sand is put into all the compartments once and then the filling sand is put in the next time, the difference in the number of filling does not exceed one time and the load on the caisson is small. Filling sand can be charged so that

  Further, in selecting the next compartment to be filled with the filling sand in steps S22 and S23, the diagonal position with little eccentricity with respect to the center of gravity of the caisson is selected with reference to the previously filled compartment. Since the compartment is selected first, and the selection of the diagonal position by the case 2 is prioritized, it is possible to uniformly fill the sand so that the caisson does not have an uneven load or tilt.

  Next, selection of a compartment based on the “clockwise arithmetic expression” in case 4 (CASE 4) in the above-described steps S27 and S28 will be described with reference to FIGS.

  FIG. 9 is a diagram for explaining step S27 and the like based on the clockwise expression (case 4) of FIG. FIG. 10 is a diagram (a) showing an XY coordinate system set to represent the position of each compartment of the caisson of FIG. 8, and a table (b) showing the definitions of numerical values used in FIG.

  As described above, the compartment to be put in after the filling of the filled sand into the compartment shown in (6) of FIG. 8 (f) has already been put in the compartment selected in steps S23 to S26. If it is determined, it is selected as follows (Case 4).

  As shown in FIGS. 10 (a) and 10 (b), XY coordinates are set for caisson compartments of 3 columns × 4 rows, and each compartment is designated as XI (I = 1, 2, 3, 4), YI. (I = 1, 2, 3)

  First, it is determined whether or not the X position of the last inserted compartment (indicated by (6) in FIG. 8F) is XI = 1 (S41). Now, since it is a case where the next compartment of the compartment (XI = 4, YI = 1) shown in (6) of FIG. 8 (f) is selected, XI = 4. Therefore, since XI = 1 is not satisfied, it is next determined whether or not XI = Xm (S45). Since Xm is the maximum value of X, XI = 4 = Xm.

  Next, it is determined whether or not YI = 1 (S46). Since YI = 1, the compartment is then selected as X = XI-1, Y = YI (S47). That is, a compartment with X = 3 and Y = 1. However, since this is the compartment shown by (3) in FIG. 8 (f) and has already been put in (S28 in FIG. 7), the process returns to step S27 in FIG. That is, the process returns to step S41 in FIG.

  Then, not XI = 1 (S41) and XI = m is not satisfied (S42), and then it is determined whether YI = 1 (S49). Since YI = 1, the compartment is then selected as X = XI-1, Y = YI (S50). That is, it is a compartment of X = 2 and Y = 1. However, this is the compartment shown by (2) in FIG. 8 (f), and since it has already been put in, it returns to step S41 again.

  Similarly, determinations in steps 41, S45, and S49 are made, and the compartment is selected as X = XI-1, Y = YI (S50). That is, a compartment with XI = 1 and YI = 1. Since this is not yet put, the filling material is put into the compartment shown by (7) in FIG. 8 (g).

  Next, another case will be described. That is, it is a case where the next compartment is selected in FIG. 8 (h) put into the compartment shown in (8). Starting from step S41. That is, it is determined whether or not the X position of the last inserted compartment (indicated by (8) in FIG. 8H) is XI = 1 (S41).

  Since the compartment indicated by (8) in FIG. 8H is XI = 4 and YI = 3, the compartment is selected as X = XI and Y = YI-1 through steps S45 and S46 ( S48). That is, it is a compartment with XI = 4 and YI = 2. Since this has not been put in yet, the filling material is put into the compartment indicated by (9) in FIG. 8 (i).

  As described above, it is possible to select the filling sand for the caisson compartment so that the caisson is not subjected to uneven load and inclination. Further, according to the compartment selection method of FIGS. 7 and 9, even when the number of caisson compartments is changed, it can be dealt with and can be applied universally.

  As described above, the modes for carrying out the present invention have been described. However, the present invention is not limited to these, and various modifications can be made within the scope of the technical idea of the present invention. For example, the selection of the compartment by the “clockwise arithmetic expression” in FIG. 9 is an example, and the compartment is selected clockwise (clockwise). However, the present invention is not limited to this. The compartment may be selected (counterclockwise).

  Further, although the display method for calling attention has been described with flicker display (blinking display), the display method is not limited to this, and display with a specific color such as red or yellow may be used.

  In addition, when displaying the position of the compartment on the display unit in order to notify the operator or the like of the next compartment to be filled with sand, the synthesized sound that generates an electronic synthesized sound together with or instead of this display You may make it instruct | indicate with an audio | voice using a means.

  Further, in this embodiment, a gut ship (self-propelled stone carrier ship having a grab lifting device) is used for transporting and charging the filling sand, but the present invention is not limited to this, for example, a boom And using a barge with a grab (non-self-propelled ship) and a carrier ship such as a barge that transports padded sand, the carrier ship can be placed next to the barge and charged with padded sand. Good.

  Although illustration of screen configuration examples of the display units 12 and 22 in steps S03, S04, S05, S07, S09, S10, S12, S14 and the like in FIG. 6 is omitted, they are based on the description in this specification. It can be configured as appropriate.

  According to the caisson filling material input management system / method of the present invention, a relatively large caisson having a plurality of compartments is installed on the water bottom ground for revetment and quay construction, etc., and then the filling material is placed in each compartment. When filling the caisson, it is possible to reliably control the filling of the filling material into the caisson, so that the caisson is free from uneven load and inclination.
