Description

Technical Field

[0001] This invention relates to the field of building pile foundation testing technology, and in particular to a tracking and positioning system and method for a counterweight block used in static load tests of pile foundations. Background Technology

[0002] Static load testing of pile foundations is the most accurate, intuitive, and reliable method for determining the ultimate bearing capacity of a single pile, and therefore it is widely used in engineering. In static load testing, a counterweight platform is often erected above the pile being tested, and hundreds or even thousands of concrete counterweights are stacked on the platform to provide load for the test. These concrete counterweights, each weighing several tons, need to be frequently moved to different construction sites and different piles for testing. These numerous, large, and heavy concrete counterweights are prone to loss or misuse during transportation, storage, and use, and their real-time location information is difficult to track, posing significant challenges to the material scheduling and asset management of testing companies. Locating and tracking the concrete counterweights is fundamental to achieving refined management, but due to their large weight, they are easily bumped during transportation and hoisting, and equipment cannot be installed on their surface. Furthermore, during stacking and storage, the counterweights are stacked in layers, making it impossible for the inner counterweights to be touched, and the shielding effect makes it difficult to send location information externally. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a tracking and positioning system and method for counterweight blocks in pile foundation static load tests.

The locator is communicatively connected to the management platform, and the management platform stores the association between the device number of the locator and the management number of the positioning counterweight.

[0008] The vehicle includes a transport flatbed and a matching charging device mounted on the transport flatbed. The transport flatbed is used to place the positioning counterweight, and the matching charging device supplies power to the locator.

[0038] To better understand the above-mentioned objectives, features, and advantages of the present invention, the solutions of the present invention will be further described below. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0039] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention, but the invention may also be practiced in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of the invention.

[0040] The tracking and positioning system for counterweights used in static load tests of pile foundations provided in this invention avoids damage to the locators during the handling of large and heavy counterweights by embedding the locators within the counterweights themselves. Furthermore, by designing the locators to communicate with each other between upper and lower layers, the system solves the problem of difficulty in acquiring and transmitting positioning data for internal counterweights during stacking, thus resolving the tracking and positioning issue of counterweights during static load tests of pile foundations. Additionally, by incorporating a charging device on the transport vehicle, the system addresses the need to recharge the locators, which are often located outdoors and difficult to access.

[0041] The following description, in conjunction with the accompanying drawings, provides an exemplary description of the tracking and positioning system for counterweights used in static load tests of pile foundations, and the tracking and positioning method for counterweights used in static load tests of pile foundations.

[0042] Figure 1 This is a schematic diagram illustrating an application scenario of a vehicle transportation positioning counterweight provided by an embodiment of the present invention. Figure 2 This is a side view of a positioning counterweight block stacked on a static load counterweight platform, provided by an embodiment of the present invention. Figure 3 This is a structural schematic diagram of a positioning counterweight provided in an embodiment of the present invention. (Combined with...) Figures 1 to 3 The tracking and positioning system for the counterweight block used in the static load test of pile foundation includes: a management platform, a positioning counterweight block 9, and a vehicle 4; the positioning counterweight block 9 includes a counterweight block 3 and a locator 1 fixed in the positioning counterweight block 9, the counterweight block 3 is provided with a through hole 10 for placing the locator 1; the locator 1 includes a locator body 7, the locator body 7 includes a positioning module 12, a mobile communication module 13, a top RFID module 14, a bottom RFID module 19, and a control module 16; the positioning module 12, the mobile communication module 13, the top RFID module 14, and the bottom RFID module 19 are all connected to the control module 16; the RFID modules (including the top RFID module 14 and the bottom RFID module 19) store the device number information of the locator 1, the locator 1 is communicatively connected to the management platform, and the management platform stores the association relationship between the device number of the locator 1 and the management number of the counterweight block 3;

[0043] Vehicle 4 includes a transport flatbed 5 and a matching charging device 2 installed on the transport flatbed 5. The transport flatbed 5 is used to place the positioning counterweight 9, and the matching charging device 2 provides power to the locator 1.

[0044] When the positioning counterweights 9 are stacked, the positioners 1 in each layer of positioning counterweights 9 are located on the same vertical axis, and adjacent positioners 1 communicate with each other through the top RFID module 14 and the bottom RFID module 19.

[0045] The counterweight 3 is made of concrete. The management platform (not shown in the figure) can be understood as an electronic device for communication, such as a computer, and is not specifically limited here. In the management platform, the device number of the locator 1 is associated with the management number of the counterweight 3 in advance, thereby establishing the association between the device number of the locator 1 and the management number of the counterweight 3.

[0046] Specifically, the positioning module 12 is used to acquire the latitude and longitude information of the counterweight 3, and the positioning module 12 can be a positioning antenna set on the top of the locator 1; the mobile communication module 13 is used to send the positioning information and status information of the locator 1 to the management platform, and the mobile communication module 13 can be a communication antenna set on the top of the locator 1; the top RFID module 14 is used to communicate with the locator 1 in the upper positioning counterweight 9 when the positioning counterweight 9 is stacked, and the top RFID module 14 can be an RFID antenna set on the top of the locator 1; the control module 16 is used to run the working program of the locator 1 and control other modules accordingly; the bottom RFID module 19 is used to communicate with the locator 1 in the lower positioning counterweight 9 when the positioning counterweight 9 is stacked, and the bottom RFID module 19 can be a communication antenna set on the bottom of the locator 1.

[0047] The vehicle 4 includes a transport flatbed 5, on which a charging device 2 is deployed to power the locator 1 in the positioning counterweight 9. During transport of the positioning counterweight 9 in the vehicle 4, to conserve power, the locator 1 can enter a sleep state. It can obtain the vehicle's location information through the vehicle positioning module (described below) and the device number information of the locator 1 through the vehicle RFID module (described below). It then sends the device number information of the locator 1 and the vehicle's location information to the management platform through the vehicle communication module. At this time, the management platform uses the vehicle location information as the location information for all locators 1 corresponding to the positioning counterweight 9 on the vehicle 4.

[0048] Specifically, when vehicle 4 transports the positioning counterweight 9 to the target location (such as the location of the static load counterweight platform 6), the positioning counterweight 9 of vehicle 4 is transferred and stacked on the static load counterweight platform 6. The stacking of the positioning counterweight 9 can be configured as follows: Figure 2 The diagram shows multiple stacked blocks. When the positioning counterweights 9 are stacked, all locators 1 located on the same vertical axis communicate with each other through the top RFID module 14 and the bottom RFID module 19. The locators 1 at the bottom upload their own device number information and other information layer by layer. The topmost locator 1 is responsible for collecting information from all the locators 1 below it. The topmost locator 1 obtains its own positioning information through the positioning module 12 and sends its positioning information and its own device number information to the management platform through the mobile communication module 13. At this time, the management platform uses the positioning information of the topmost locator 1 as the positioning information of all locators 1 in the stack corresponding to the positioning counterweights 9. When the locators 1 are working, the communication strategy is adjusted to achieve synchronous communication between the upper and lower layer locators 1 and dynamically adjust the data transmission frequency.

[0049] In some implementations, if the positioning counterweights 9 are not stacked, the positioning information of a single positioner 1 is used as the positioning information of its corresponding positioning counterweight 9.

[0050] Afterwards, the information of the positioning counterweight 9 is visualized through the management platform, making it convenient for managers to query, count and analyze.

[0051] Therefore, by designing the locator 1 to be embedded in the counterweight 3 to form the positioning counterweight 9, the problem of the locator 1 being damaged by bumps when transporting the large and heavy counterweight 3 is avoided; and by designing the locator 1 to communicate between the upper and lower layers, the problem of the difficulty in obtaining and sending the positioning information of the internal counterweight 3 when the counterweight 3 is stacked is solved; and by using the matching charging equipment 2 on the transport vehicle 4, the problem of recharging the locator 1, which works outdoors for a long time and is difficult to reach, is solved.

[0052] The tracking and positioning system for positioning counterweights in static load tests of pile foundations provided in this embodiment of the invention includes: a management platform, positioning counterweights, and a vehicle; the positioning counterweights include a counterweight block and a locator fixed in the counterweight block, the counterweight block having a through hole for placing the locator; the locator includes a locator body, the locator body including a positioning module, a mobile communication module, a top RFID module, a bottom RFID module, and a control module; the positioning module, mobile communication module, top RFID module, and bottom RFID module are all connected to the control module; the RFID module stores the device number information of the locator, the locator is communicatively connected to the management platform, and the management platform stores the association relationship between the device number of the locator and the management number of the counterweight block; the vehicle includes a transport flatbed and a matching charging device mounted on the transport flatbed, the matching charging device supplying power to the locator; when the positioning counterweights are stacked, the locators in each layer of positioning counterweights are located on the same vertical axis, and adjacent locators communicate with each other through the top RFID module and the bottom RFID module. By designing the locator to be embedded in the counterweight block, the problem of damage to the locator during the handling of large and heavy counterweight blocks is avoided. By designing the locator to communicate with each other between upper and lower layers, the problem of difficulty in obtaining and transmitting positioning data of internal counterweight blocks during stacking is solved, as well as the problem of tracking and positioning the counterweight blocks during static load tests of pile foundations. Furthermore, by using a matching charging device on the transport vehicle, the problem of recharging the locator, which operates outdoors for extended periods and is difficult to access, is solved.

[0053] In some embodiments, such as Figure 1 As shown, the transport flatbed 5 is provided with multiple dividing elements 8, which divide the transport flatbed 5 into multiple positioning counterweight block placement areas 26; the positioning counterweight block placement areas 26, the positioning counterweight blocks 9 and the matching charging equipment 2 are set up one-to-one.

[0054] Specifically, by setting a separator element 8 on the transport flatbed 5 as a separator, it is ensured that when each positioning counterweight 9 is placed in the corresponding position on the vehicle 4, the bottom of the locator 1 in the embedded positioning counterweight 9 can be set in a position corresponding to the matching charging device 2 on the vehicle 4, thereby enabling the matching charging device 2 to supply power to the locator 1 in the positioning counterweight 9.

[0055] In some embodiments, Figure 4 This is a structural block diagram of a vehicle according to an embodiment of the present invention. (In conjunction with...) Figure 1 , Figure 3 and Figure 4 The locator body 7 includes a battery module 17 and a first wireless charging module 18 connected to the battery module 17. The battery module 17 is connected to the control module 16.

[0056] The supporting charging device 2 includes a second wireless charging module 25, and the vehicle 4 includes a power supply module 21 and a vehicle power supply 20. The power supply module 21 is connected between the vehicle power supply 20 and the second wireless charging module 25. The supporting charging device 2 is set up corresponding to the first wireless charging module 18.

[0057] The battery module 17 can be a rechargeable battery pack. The power information of the locator 1 (i.e. the power of the battery module 17) can be transmitted to the management platform through the mobile communication module 13 to obtain the power information of the locator 1.

[0058] Specifically, the second wireless charging module 25 (wireless charging module) in the supporting charging device 2 is deployed on the transport flatbed 5 of the vehicle 4 and corresponds to the position of the first wireless charging module 18 (wireless charging module) of the locator 1, thereby realizing wireless charging for the locator 1; and the power supply module 21 is used to obtain power from the vehicle power supply 20 of the vehicle 4 and drive the second wireless charging module 25 to work.

[0059] In some embodiments, such as Figure 4 As shown, vehicle 4 includes a vehicle communication module 23, a vehicle RFID module 24, and a vehicle positioning module 22;

[0060] The vehicle RFID module 24 is used to read the device number information of the locator 1 and transmit it to the management platform through the vehicle communication module 23. The vehicle positioning module 22 is used to obtain vehicle positioning information and transmit it to the management platform through the vehicle communication module 23. It should be noted that multiple vehicle RFID modules 24 are set in the vehicle 4, and each vehicle RFID module 24 is set in a one-to-one correspondence with the positioning counterweight placement area 26.

[0061] Specifically, during vehicle transportation, the locator 1 can enter a dormant state, obtain the vehicle's location information through the vehicle positioning module 22, and obtain the device number information of the locator 1 through the vehicle RFID module 24. It can also send the device number information of the locator 1 and the vehicle location information to the management platform through the vehicle communication module 23. At this time, the management platform uses the vehicle location information as the location information of the positioning counterweight 9 corresponding to all locators 1 on the vehicle 4.

[0062] In some embodiments, such as Figure 3 As shown, the locator body 7 includes an acceleration sensor 15 connected to the control module 16. Specifically, the acceleration sensor 15 is configured to acquire the motion state of the positioning counterweight 9 and transmit it to the management platform via the mobile communication module 13.

[0063] In some embodiments, such as Figure 3 As shown, the locator 1 includes a housing 11, and the locator body 7 is located inside the housing 11. Specifically, by providing the housing 11, the locator body 7 is fixed inside the housing 11, which can protect the locator body 7 and thus extend the service life of the locator 1.

[0064] In some embodiments, such as 1 to Figure 3 As shown, the tracking and positioning system for the counterweight blocks used in the static load test of the pile foundation also includes: a static load counterweight platform 6, which is used to stack and position the counterweight blocks 9 to realize the static load test of the pile foundation.

[0065] Specifically, when vehicle 4 transports the positioning counterweight 9 to the location of the static load counterweight platform 6 to conduct the static load test of the pile foundation, the positioning counterweight 9 of vehicle 4 is transferred and stacked on the static load counterweight platform 6. The stacking of the positioning counterweight 9 can be as follows: Figure 2 The multiple stacked blocks shown.

[0066] In some embodiments, such as Figure 2 As shown, along the placement direction of the counterweight 3, the top surface of the through hole 10 is lower than the top surface of the counterweight 3; the bottom surface of the through hole 10 is higher than the bottom surface of the counterweight 3.

[0067] Specifically, in order to protect the locator 1 from damage during the handling of the positioning counterweight 9, the height of the housing of the embedded locator 1 should be slightly less than the height of the counterweight 3, so that after installation, the top and bottom surfaces of the locator 1 are slightly lower than the surface of the counterweight 3.

[0068] In some embodiments, the counterweight 3 is in the shape of a cuboid, and the length-to-width ratio of each counterweight 3 is 2:1; the shape of the long and wide face of the counterweight 3 is a rectangle, and the rectangle includes two equal squares.

[0069] Each positioning counterweight 9 includes a first through hole and a second through hole disposed in the counterweight 3, as well as a first locator located in the first through hole and a second locator located in the second through hole; the first through hole and the second through hole are respectively disposed at the center of two squares on the long and wide sides of the counterweight 3.

[0070] Specifically, the number and position of the embedded locators 1 installed in each counterweight 3 should ensure that, when the counterweights 9 are stacked, the locators 1 in each layer of counterweights 9 are exactly located on the same vertical axis. Taking a common counterweight 9 with a length-width-height ratio of 2:1:1 as an example, such counterweights 9 are often stacked vertically or staggered, so one embedded locator 1 can be installed at 1 / 4 of the length and another at 3 / 4 of the length. Figure 2 The method of stacking the positioning counterweights 9 in the middle helps to ensure the stability of the positioning counterweights 9 when stacked. Therefore, two through holes 10 (a first through hole and a second through hole) are provided for each counterweight 3.

[0071] In some embodiments, a through hole 10 can be provided for each counterweight 3, so that when the positioning counterweights 9 are stacked, the positioners 1 in each layer of positioning counterweights 9 can be located exactly on the same vertical axis. This embodiment of the present invention does not limit this.

[0072] In some embodiments, the management platform includes a visualization module.

[0073] Therefore, the location information, device serial number information, and power information collected by the locator are transmitted to the management platform, through...

[0074] The management platform can provide a visual display of the positioning counterweight information, making it convenient for managers to query, compile statistics, and analyze.

[0075] Based on the above embodiments, this invention also provides a tracking and positioning method for counterweight blocks in static load tests of pile foundations. This method is implemented using the tracking and positioning system for counterweight blocks in static load tests of pile foundations described above, and therefore has the same or similar beneficial effects, which will not be elaborated here.

[0076] Figure 5 This is a flowchart illustrating a method for tracking and locating a counterweight block in a static load test of a pile foundation, provided by an embodiment of the present invention. Figure 5 As shown, the tracking and positioning method includes the following steps:

[0077] S501. Prepare a counterweight block with a through hole, and fix the positioner in the through hole to form a positioning counterweight block.

[0078] Specifically, in this step, the embedded locator is embedded into the counterweight block (concrete) by pre-embedding before pouring or drilling and bolting afterward. In order to protect the locator from being damaged by bumps during the transportation of the counterweight block, the height of the embedded locator should be slightly less than the height of the counterweight block, so that after installation, the top and bottom surfaces of the locator are slightly lower than the surface of the counterweight block.

[0079] S502. Use a vehicle to transport the positioning counterweight to the target location.

[0080] Specifically, in this step, the positioning counterweight prepared in S501 is transferred to a vehicle, and the vehicle is used to transport the positioning counterweight to the target location.

[0081] S503. Stack the positioning counterweights at the target location. When stacking the positioning counterweights, the positioners in each layer of positioning counterweights are located on the same vertical axis. The positioners in adjacent layers of positioning counterweights communicate with each other. The positioners in the inner layers of positioning counterweights upload the collected equipment information layer by layer to the top positioner. The top positioner transmits the equipment information it has collected and the equipment information collected by other inner positioners to the management platform. The equipment information includes at least positioning information and equipment number information.

[0082] Specifically, in this step, when the positioning counterweights are stacked, multiple positioning counterweights are stacked to form multiple stack blocks. During stacking, the locators located on the same vertical axis communicate with each other through the top RFID module and the bottom RFID module. The locators at the bottom upload their own device number, power level, and other information layer by layer. The locator at the top is responsible for collecting information from all the locators below it. The topmost locator obtains its own positioning information through the positioning module and sends its own positioning information, as well as the numbers and power levels of all the locators below it, to the management platform through the mobile communication module. At this time, the management platform uses the positioning information of the topmost locator as the positioning information of the corresponding positioning counterweight for all locators in that column.

[0083] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0084] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
