DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The term "and / or" used herein includes any and all combinations of one or more of the associated listed items.
[0026] Referring to FIG. 1, an embodiment of the present application provides an intelligent adjustment control method for the positioning and sinking rope of an open caisson, The method includes step S10 of receiving specified data and solving the attitude data of the open caisson 1.
[0027] Here, the predetermined data includes GPS (Global Positioning System) data of the open caisson 1, and the stroke and hydraulic pressure of the cylinder 6. The attitude data includes coordinate information and attitude angle.
[0028] First, it is necessary to clarify two coordinate systems: the geodetic coordinate system and the local coordinate system. The geodetic coordinate system is the CGCS2000 geodetic coordinate system, and if the original data is not in this coordinate system, it is necessary to give a formula to convert the original data into this coordinate system. The origin of the local coordinate system is the platform center (the center of the same plane of multiple rope connection points 4) when the open caisson 1 is at the target position, and the local coordinate system is established by defining the south side as the +X direction and the east side as the +Y direction, and the Z coordinate coincides with the geodetic coordinate system.
[0029] The predetermined data further includes constant data and real-time data. The constant data does not need to be provided in real time via the local area network 14, and specifically includes the coordinates of each fixed anchor 3 in the geodetic coordinate system and the local coordinate system, the coordinates of each rope connection point 4 in the local coordinate system, the coordinates of the four vertices 5 (coplanar with each rope connection point 4) in the local coordinate system, and the maximum error limit. The maximum error limit includes the deflection angle (angle deviation from the target position around the Z axis), the verticality requirement in both directions, and the planar deviation distance (distance deviation on the XOY plane of the center point). The real-time data needs to be provided in real time by the local area network 14, and specifically includes the data of the inclinometer attached to the platform of the open caisson 1, and the real-time coordinates of the four vertices 5, the rope connection points 4, and the center point O in the geodetic coordinate system.
[0030] The predetermined data may further include rope 2 operation information including operating status and anchor rope force transmitted via the local area network 14 .
[0031] In step S20, it is determined whether the acting force of cylinder 6 is within the effective range. If the answer is yes, the process proceeds to the next step S30. If the answer is no, the operation is stopped and an alarm is issued to notify the user to switch to manual operation.
[0032] Here, the force acting on the cylinder 6 is equal to the product of the hydraulic oil pressure and the piston area, the hydraulic oil pressure is the hydraulic pressure in predetermined data, and the piston area can be obtained in advance based on the specifications of the cylinder 6. The cylinder 6 in this application is a hydraulic cylinder 6. If the position of the open caisson 1 is controlled simply by the distance, there is a possibility that the deviation in the force received by the ropes 2 will be excessive, so it is necessary to judge whether the force received by each rope 2 is within a safe range by the cylinder 6 pressure, that is, whether tightening or loosening of each rope 2 can be performed is judged depending on whether the cylinder 6 pressure is within the allowable range.
[0033] In step S30, the length deviation value of the multiple ropes 2 at the current sinking height of the open caisson 1 is calculated.
[0034] Here, the length deviation value is obtained from the difference between the target length and the actual length, and the length in this application is approximated by the distance between two points, and the distance is calculated from the distance formula for two points in space. For example, the spatial coordinates of point C are ( TIFF2025073041000014.tif814), and the spatial coordinates of point B are ( TIFF2025073041000015.tif814), then the distance between point C and point B is The result is TIFF2025073041000016.tif867.
[0035] Specifically, step S30 includes the following steps: Target length of each of the multiple ropes 2 at the current sinking height of the open caisson 1 A step S301 of calculating TIFF2025073041000017.tif86; Actual length of each of the multiple ropes 2 at the current sinking height of the open caisson 1 a step S302 of calculating TIFF2025073041000018.tif86; Length deviation value of each of the multiple ropes 2 at the current sinking height of the open caisson 1 and step S303 of calculating TIFF2025073041000019.tif827.
[0036] where n = 1, 2, 3, ..., k, and k is the total number of ropes 2. TIFF2025073041000020.tif86 is the target length of the nth rope at the current sinking height of open caisson 1. TIFF2025073041000021.tif86 is the actual length of the nth rope at the current sinking height of the open caisson 1, and the other parameters have similar definitions, so further explanation is omitted.
[0037] Target Length TIFF2025073041000022.tif86 is the distance between the connection point of the rope 2 and the open caisson 1 and the fixed anchor 3 submerged in water when the open caisson 1 is in its theoretical position. Specifically, TIFF2025073041000023.tif86 is the distance between the connection point of the rope 2 and the open caisson 1 at the actual position of the open caisson 1 and the fixed anchor 3 submerged in water. The deviation value of both Based on TIFF2025073041000024.tif88, the operating state (whether to tighten or loosen) of each rope 2 is determined. Details will be given later.
[0038] Here, the distance between the approximate reference points is approximated to the length of the rope 2 (the rope 2 is in a taut state during operation), and then the deviation of the rope 2 is calculated to determine the operation target of the cylinder 6. During actual operation, there is a difference between the deviation of the rope 2 and the amount that the rope 2 should actually move (the effect of the rope 2 being deformed), which is actually the deviation of the distance between the characteristic points. With the operation of the rope 2, the smaller the deviation of the distance, the closer the open caisson 1 is to the target position.
[0039] In step S40, the absolute values of the length deviation values of the multiple ropes 2 are sorted, and rope A with the largest absolute value is obtained, and the other ropes 2 are wound up or down based on rope A.
[0040] Here, rope A, which has the largest absolute value of the length deviation, does not need to be adjusted, and by simply adjusting the other ropes 2, the amount of adjustment can be reduced and work efficiency can be improved.
[0041] In step S50, it is determined whether the length deviation value satisfies a predetermined condition. If it does, the cylinder 6 stops operating and the adjustment is completed. If it does not, the process proceeds to the next step S60.
[0042] However, the predetermined conditions are: TIFF2025073041000025.tif825 or The file is TIFF2025073041000026.tif831. TIFF2025073041000027.tif813 is the length deviation value of multiple ropes at the previous sinking height of the open caisson (abbreviated as the previous length deviation value) (or, TIFF2025073041000028.tif813 shows the length deviation value at the sinking height of the open caisson where it was last positioned and sunk. The specified conditions are that the absolute value of the length deviation value is less than 50 mm, the previous length deviation value is 0, the current length deviation value is 0, or neither the previous nor current length deviation value (the length deviation value at the current sinking height of the open caisson) is 0 but the signs of the two are opposite.
[0043] Step S60: Length deviation value for each rope 2 Determine whether TIFF2025073041000029.tif88 is less than 0, and if yes, the cylinder 6 winds up the rope 2, and if no, the cylinder 6 winds down the rope 2.
[0044] Here, the length deviation value If TIFF2025073041000030.tif88 is less than 0, that is, the target length of rope 2 is smaller than the actual length, it is necessary to tighten rope 2, so let cylinder 6 wind rope 2, and the length deviation value If TIFF2025073041000031.tif88 is greater than 0, i.e., the target length of rope 2 is greater than the actual length, rope 2 needs to be slackened, so cylinder 6 is caused to wind rope 2 down.
[0045] In step S70, a deviation change error is calculated based on rope A as a reference.
[0046] Specifically, step S70 includes the following steps: Deviation change rate A step S701 of calculating TIFF2025073041000032.tif830; Deviation change error and a step S702 of calculating TIFF2025073041000033.tif823.
[0047] however, TIFF2025073041000034.tif815 is the absolute value of the length deviation value of multiple ropes at the previous sinking height of the open caisson, TIFF2025073041000035.tif810 is the absolute value of the length deviation value of multiple ropes at the current sinking height of the open caisson, TIFF2025073041000036.tif84 is the deviation change rate of rope A.
[0048] In step S80, the adjustment range of the cylinder 6 acting force is calculated based on the deviation change error using PID (Proportional Integral Derivative), and the process returns to the step of determining whether the cylinder 6 acting force is within the effective range (i.e., step S20).
[0049] Specifically, step S80 uses PID to calculate the PWM (Pulse Width Modulation Wave) value of the flow valve. Includes calculating TIFF2025073041000037.tif830.
[0050] The intelligent adjustment control method for the positioning sinking rope of an open caisson provided in this embodiment first accepts predetermined data, solves the posture data of the open caisson 1, and first determines whether the cylinder 6 acting force is within the effective range before adjustment, thereby determining whether the rope 2 can be tightened or loosened. If the position of the open caisson 1 is controlled simply by distance, the deviation of the force received by the rope 2 may be excessive, so it is necessary to determine whether the force received by each rope 2 is within a safe range by the cylinder 6 pressure. After confirming that the cylinder 6 acting force is within the effective range, calculate the length deviation value of each rope 2, and take the rope A with the largest absolute value of the length deviation value as a reference to wind up or wind down the other ropes 2. If the length deviation value meets the predetermined condition, the adjustment process can be completed; if the length deviation value does not meet the predetermined condition, after winding or winding down, further calculate the deviation change error based on the rope A, and use the PID to calculate the adjustment range of the cylinder 6 acting force based on the deviation change error, and return to the step of determining whether the cylinder 6 acting force is within the effective range to continue the adjustment. This intelligent adjustment control method for the open caisson positioning sinking rope can improve the accuracy of the open caisson 1 during sinking and landing by timely adjusting the position of the open caisson 1 during sinking and landing through control over the rope 2 and intelligent adjustment control.
[0051] Refer to Figures 2 to 4. The embodiment of the present application further provides an intelligent adjustment control system for an open caisson positioning submersion rope, which includes a cylinder 6, a pump station 7, an industrial computer 8, an installation meter 9 and a server 10.
[0052] Here, the cylinder 6 was fixed and installed on the open caisson 1. One cylinder 6 was arranged for each rope 2. The cylinder 6 was provided with a cylinder sensor for feeding back the stroke and hydraulic pressure of the cylinder 6. As shown in FIG. 3, when the platform of the open caisson 1 was installed, 12 ropes 2 were arranged, including 8 main ropes (8 ropes 2 located on the left and right sides of FIG. 3) and 4 edge ropes (4 ropes 2 located on the upper and lower sides of FIG. 3), and one 350t cylinder 6 was arranged on each rope 2, requiring a total of 12 350t cylinders 6, and the arrangement of the cylinders 6 is as shown in FIG. 3.
[0053] When installing the cylinder 6, a positioning mark is made on the tension beam, and the 350t cylinder 6 is hoisted to the corresponding position by a crane. When the 350t cylinder 6 is hoisted, each cylinder 6 is fixed by welding with four 7-shaped chucks, and the 7-shaped chucks hook the cylinder 6 to the lower anchor bottom plate 65, requiring a total of 48 7-shaped chucks (plate thickness 20 mm). When hoisting the cylinder 6, attention should be paid to the hole position direction of the hydraulic lock and stroke sensor to make it easier to connect the high-pressure oil pipe and install the sensor.
[0054] 4, the cylinder 6 includes, from top to bottom, a guide plate 61, an upper anchor cylinder 62, a master cylinder 63, a lower anchor cylinder 64, and a bottom plate 65. An upper support pillar 66 is provided between the guide plate 61 and the master cylinder 63 so as to surround the outside of the upper anchor cylinder 62, and a lower support pillar 67 is provided between the master cylinder 63 and the bottom plate 65 so as to surround the outside of the lower anchor cylinder 64.
[0055] The cylinder sensors include a stroke sensor, an anchor sensor, and a pressure sensor. Each cylinder 6 was fitted with one stroke sensor for providing feedback on the position of the cylinder 6 in real time. The upper anchor cylinder 62 and the lower anchor cylinder 64 of each cylinder 6 were each fitted with one anchor sensor for providing feedback on the anchor state in real time. Each cylinder 6 was fitted with one pressure sensor for monitoring the force received by the tension wire, and the pressure sensor was attached to the large cavity side of the cylinder 6. The various sensors were connected to their respective communication modules.
[0056] As shown in Fig. 3, the pump stations 7 were fixedly installed on the open caisson 1. The number of the pump stations 7 is half the number of the cylinders 6. One pump station 7 is provided between two adjacent cylinders 6 and is used to drive the two cylinders 6. The pump station 7 in this application is a hydraulic pump station 7.
[0057] When arranging the pump stations 7, the power supplied by the pump stations 7 should be able to ensure a sufficient rising speed, and they should be arranged close to each other and the length of the oil pipes should be short. The types of cylinders 6 driven by the pump stations 7 are the same, which increases the utilization efficiency of the pump stations 7. Specifically, six pump stations 7 are selected for positioning, and each pump station 7 is arranged in the center of two cylinders 6. The arrangement of the pump stations 7 is shown in Figure 3.
[0058] When installing the pump station 7, the weight of the pump station 7 is about 3 tons, and two wire ropes are required for hanging, and the diameter must be more than 15 mm. Each pump station 7 requires a 380V distribution box and a 160A air switch is placed, and six distribution boxes are placed for the entire positioning of the open caisson 1 platform, and the distribution box must be placed next to the pump station 7. The power of each pump station 7 is 55KW, and the total power is 330KW. To ensure smooth hoisting, the hoisting power source needs to be monitored by the person in charge during positioning. When constructing the platform positioning, each pump station 7 drives two cylinders 6, and the oil pipe connects the pump station 7 and the two cylinders 6.
[0059] The pump station 7 drives the cylinders 6, and generally, one pump station 7 can drive four cylinders 6 simultaneously. The pump station 7 includes two power paths, E and F, which lift and drive the master cylinder 63. The hydraulic principle of these two paths is the same. Two cylinders 6 are connected to each path, and the direction of motion of the cylinders 6 is changed by controlling the solenoid valves SU_E (SU_F) and SE_E (SE_F), and the speed of motion of the cylinders 6 is adjusted by controlling the proportional speed control valve PWM_E (PWM_F). Since two cylinders 6 are connected to the same circuit, it is necessary to control the operation of each cylinder 6 individually by controlling the shutoff valves T1, T2, T3, and T4. The pump station 7 also includes two circuits that control the upper anchor cylinder 62 and the lower anchor cylinder 64, and realizes the tightening and loosening operations that are offset up and down by controlling the solenoid valves SS, SJ, XS, and XJ.
[0060] After power is sent to the air switch in the pump station 7 and the power is turned on, the motor can be started by directly operating the button on the panel of the electrical cabinet. The 22kW main pump motor is a Y- TIFF2025073041000038.tif83 Startup, the motor of the anchor pump is star-connected and starts directly. Pump station 7 has a motor TIFF2025073041000039.tif83It can only be operated once it is switched to the working state.
[0061] When starting the motors, pay attention to their direction of rotation, look down from the top of pump station 7, the motor fan should rotate clockwise (or start the anchor pump and check whether there is pressure indication in the anchor oil passage, if there is pressure, it is forward rotation), if not, replace the two phases in the wiring. When starting the motors, pay attention to make sure that all operation buttons are in the "Stop" position, otherwise the motor may be overloaded and damaged due to excessive load.
[0062] An operation control panel can be provided in the electrical cabinet of the pump station 7, when the "manual / auto" switch in the panel is switched to the "manual" range, the switch in the panel is selected to control the state locally, if it is switched to the "auto" range, the external control cabinet (i.e. the master controller) is selected to control the state remotely, at this time the button in the electrical cabinet of the pump station 7 is disabled. If the pump station 7 and the corresponding oil pipe of the cylinder 6 are properly connected, the cylinder 6 can operate accordingly. An operation check must be done before starting the hoisting operation, and there is one anchor that is always kept in the "tight" state. The following describes each operation switch in the panel. "Cylinder extension": The cylinder extension solenoid valve of the directional control valve is energized to perform the cylinder extension operation, and is electrically locked with the "cylinder retraction" "Cylinder retraction": The cylinder retraction solenoid valve of the directional control valve is energized to perform the cylinder retraction operation, and this is electrically locked together with the "cylinder extension". When "bottom tightening" and "top tightening" are performed at the same time, the cylinder extension and cylinder retraction operations are disabled.
[0063] "T1, T3": Normally, it is in the "on" range, but when it is switched to the "off" range, the T1, T3 cutoff valve solenoid valve is energized, the branch telescopic cylinder oil path is cut off, and the cylinder 6 of this path stops operating. "T2, T4": Normally, it is in the "on" range. When it is switched to the "off" range, the T2, T4 cutoff valve solenoid valve is energized, the branch telescopic cylinder oil path is cut off, and the cylinder 6 of this path stops operating. "Top tightening": The top tightening solenoid valve of the top anchor switching valve is energized, the anchor cylinder 6 of the top anchor operates, and the top anchor is tightened. "Upper loosening": The upper loosening solenoid valve of the upper anchor switching valve is energized, the anchor cylinder 6 of the upper anchor operates, and the upper anchor is loosened. “Bottom tightening”: The bottom tightening solenoid valve of the bottom anchor switching valve is energized, the anchor cylinder 6 of the lower anchor operates, and the lower anchor is tightened. “Lower loosening”: The lower loosening solenoid valve of the lower anchor switching valve is energized, the anchor cylinder 6 of the lower anchor operates, and the lower anchor is loosened. In addition to the several operating switches mentioned above, there is an "emergency stop" switch, and when the "emergency stop" button is pressed, none of the solenoid valves are activated.
[0064] The proportional flow valve can be adjusted with a knob on the operation panel, and a numeric meter displays the magnitude of the flow adjusted by the proportional flow valve.
[0065] If the pump station 7 and the corresponding oil pipes of the cylinders 6 are properly connected, each operation button (knob) corresponds to the operation of one cylinder 6. The upper anchor cylinder 62 and the lower anchor cylinder 64 can both set the upper and lower anchors to the anchor tightening state, but since it is never permitted to set both the upper and lower cylinders 6 to the anchor loosening state, when both knobs are in the anchor loosening state, all operation operations are invalid.
[0066] In this embodiment, the installation meter 9 is fixedly installed in the open caisson 1 to monitor the GPS data of the open caisson 1. As shown in Figure 2, the industrial personal computer 8, the installation meter 9 and the server 10 transmit information via a local area network 14.
[0067] The industrial PC 8 is electrically connected to the pump station 7 and the cylinder 6, and is used to execute the intelligent adjustment control method of the open caisson positioning sinking rope described in any of the above embodiments. The industrial PC 8 is arranged in the main control room, and a pump station communication line 12 and a cylinder sensor communication line 11 are drawn from the industrial PC 8. The pump station communication line 12 and the cylinder sensor communication line 11 are both CAN (Controller Area Network, Controller Local Area Network 14) buses. The cylinder sensor operating power line is drawn from the pump station 7 end.
[0068] The industrial computer 8 is the core of the adjustment system, and performs functions such as command collection, logical operation, and control command transmission, and transmits control data to the electric cabinet of the pump station 7 to be controlled after logical operation. The electric cabinet of the pump station 7 receives the control data from the industrial computer 8 and drives the output. The cylinder sensor collects stroke and hydraulic data of the cylinder 6 and feeds it back to the industrial computer 8. The server 10 is responsible for interacting with the GPS data and the computer, and transmits information through the local area network 14. When operating normally, the cylinder 6 and the pump station 7 communicate with the industrial computer 8 respectively through the CAN bus. The industrial computer 8 issues control commands based on the received feedback signal of the cylinder 6 and the GPS information downloaded from the server 10 end.
[0069] Specifically, the status data of the cylinder 6 is transmitted to the cylinder sensor communication line 11 via the cylinder sensor, and the sensor mainly detects the status of the upper / lower anchor, the stroke, and the hydraulic pressure of the cylinder 6. The industrial computer 8 and the cylinder sensor are connected via the cylinder sensor communication line 11, and the industrial computer 8 receives the status of the anchor, the cylinder 6 formation, and the hydraulic pressure of the cylinder 6 via the cylinder sensor communication line 11.
[0070] The GPS data of the open caisson 1 is measured by an installed meter 9 (i.e., a GPS base station) placed on the open caisson 1 and transmitted to the server 10 via a 4G or wifi network, and the data is solved at the server 10 end to obtain the coordinate information and attitude angle of the open caisson 1, which are then transmitted to the industrial computer 8 via a wireless network. The HTTP protocol is adopted as the network communication protocol.
[0071] The industrial computer 8 and the pump station 7 are connected via a pump station communication line 12, and the industrial computer 8 analyzes the collected information, performs logical operations, and then transmits control commands to the pump station communication line 12. The control commands mainly include the extension and contraction of the E / F line cylinder, the tightening and loosening of the upper and lower anchors, the control of the shutoff valve, and the adjustment of the E / F line proportional valve.
[0072] The position adjustment of the open caisson 1 needs to realize lateral movement, vertical movement and rotation in the horizontal plane, and the master controller controls the unified operation of continuously raising the cylinders 6 for each adjustment point, while monitoring the tensile load to avoid overloading the load. Each cylinder 6 corresponds to one adjustment point, and each adjustment point meets the needs of hoisting and sinking according to the need for adjusting the position of the open caisson 1, and by adjusting the hoisting and sinking of each cylinder 6, the change in the position of the open caisson 1 in the forward, backward, left and right directions can be realized, and the position of the open caisson 1 that meets the design requirements can be reached.
[0073] In one embodiment, the system may further include a monitor 13 electrically connected to the industrial PC 8 for displaying the equipment status on a large screen.
[0074] In addition, the industrial computer 8 can execute the intelligent adjustment control method of the positioning and sinking rope of the open caisson described in any of the above embodiments, and the detailed description of the relevant content is referred to the above method section, so that the detailed description is omitted here. In this embodiment, the embodiment of the intelligent adjustment control system of the positioning and sinking rope of the open caisson corresponds to the method embodiment, and can solve the technical problems solved by the method embodiment, and accordingly achieve the technical effects of the method embodiment, and the specifics are omitted here in this application.

That is, the data receiving solver module is used to perform step S10 in the intelligent adjustment control method of the positioning sinking rope of the open caisson.
[0077] The first judgment module is used to judge whether the cylinder acting force is within the effective range. If yes, proceed to the next step, and if no, stop the operation and issue an alarm to switch to manual operation. That is, the first judgment module is used to perform step S20 in the intelligent adjustment control method for the positioning sinking rope of the open caisson.
[0078] The deviation calculation module is used to calculate the length deviation value of the multiple ropes at the current sinking height of the open caisson, that is, the deviation calculation module is used to perform step S30 in the above-mentioned intelligent adjustment control method for the positioning sinking rope of the open caisson.
[0079] The rope calibration module is used to sort the absolute values of the length deviation values of multiple ropes to obtain rope A with the largest absolute value, and then wind up or wind down other ropes based on rope A. That is, the rope calibration module is used to perform step S40 in the above-mentioned method for intelligent adjustment control of the positioning and sinking rope of an open caisson.
[0080] The second judgment module is used to judge whether the length deviation value meets the predetermined condition. If it meets the predetermined condition, the cylinder stops working and completes the adjustment. If it does not meet the predetermined condition, proceed to the next step. That is, the second judgment module is used to perform step S50 in the above-mentioned intelligent adjustment control method for the positioning sinking rope of the open caisson.
[0081] The third judgment module is used to judge whether the length deviation value is less than 0. If yes, the cylinder winds up the rope, and if no, the cylinder winds down the rope. That is, the third judgment module is used to perform step S60 in the above-mentioned intelligent adjustment control method for the positioning and sinking rope of the open caisson.
[0082] The error calculation module is used to calculate the deviation change error based on the rope A. That is, the error calculation module is used to perform step S70 in the above-mentioned intelligent adjustment control method for the positioning and sinking rope of the open caisson.
[0083] The width adjustment module is used to calculate the adjustment width of the cylinder acting force by using PID according to the deviation change error, and to return to the step of determining whether the cylinder acting force is within the effective range. That is, the width adjustment module is used to perform step S80 in the intelligent adjustment control method for the positioning sinking rope of the open caisson.
[0084] It should be noted that each module in the intelligent adjustment control equipment for the positioning and sinking rope of the open caisson is respectively used to perform each step in the above-mentioned intelligent adjustment control method for the positioning and sinking rope of the open caisson, and the detailed description of the relevant content can be referred to the above-mentioned method part, and the detailed description is omitted here.
