Description

Technical Field

[0001] This invention relates to a building lifting control technology, and more particularly to a building lifting control method and terminal with non-communication multi-system extended linkage. Background Technology

[0002] Building jacking technology is a construction method that uses equipment such as hydraulic jacks to vertically lift an existing building, either as a whole or in part, to the design elevation. It is widely used in building renovation, correction of deviations, cultural relic protection, and subway overpass development.

[0003] Specifically, a hydraulic system generates jacking force, which, in conjunction with a reaction frame and a synchronous control system, transfers the building load to a temporary support structure. The equipment used mainly includes: clusters of jacks, high-pressure oil pumps, displacement sensors, inclinometers, laser rangefinders, and so on.

[0004] The main processes of building lifting operations include:

[0005] 1) Construct a lifting foundation structure for the building to be lifted;

[0006] 2) Plan the lifting control points for the building to be lifted;

[0007] 3) Install and configure jacks for lifting at the lifting control points, set up corresponding synchronous control systems for the control of these jacks, and configure corresponding sensors.

[0008] 4) When controlling the jack to perform the lifting action, the lifting can be carried out in stages and synchronously, and the lifting height of each round shall not exceed the stroke of the jack.

[0009] Currently, the building lifting operation process using existing technologies is roughly as described above.

[0010] In the field of construction engineering, during the construction processes such as building offset correction and foundation pit servo support, a lifting control system is required to achieve precise control of multiple control points. This type of lifting control system typically has sensor data acquisition (such as displacement and pressure signals) and actuator action control (such as relay switch output to drive jacks to lift or unload). A single independent lifting control system can be responsible for the data acquisition and control output of a certain number of control points.

[0011] However, in practical engineering projects, more control points are often required to work together. Due to limitations in the hardware computing and storage capabilities, communication capabilities, and software architecture design of the lifting control system, the number of independent control points in a single lifting control system typically has an upper limit. When the number of control points in a single lifting control system is less than the required number, it is necessary to use two or more lifting control systems to expand and coordinate control to meet the engineering requirements.

[0012] The core of joint control of multiple lifting control systems is collaborative operation, but existing technologies have significant drawbacks:

[0013] On the one hand, most conventional lifting control systems are not designed with data access or output exchange functions, and cannot directly realize information sharing between systems;

[0014] On the other hand, developing a separate data exchange module to achieve information exchange would require significant R&D costs and could lead to decreased system stability due to compatibility issues. These problems can cause coordination delays or even failures to coordinate when multiple systems are linked for control, as well as insufficient control precision or even the risk of loss of control, seriously affecting project quality and safety.

[0015] In summary, the current problem is:

[0016] The use of multiple lifting control systems in conjunction with each other to lift a building presents numerous technical challenges and is difficult to implement. Summary of the Invention

[0017] The purpose of this invention is to provide a building lifting control method and terminal with non-communication multi-system extended linkage. This building lifting control method can perfectly realize the linkage control of multiple lifting control systems by using simple technical means.

[0018] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0019] A building lifting control method with non-communication multi-system extended linkage is disclosed. The method includes: dividing the building to be lifted into multiple lifting control zones, and configuring a lifting control system for each lifting control zone; for all lifting control zones, determining one lifting control zone as the core control zone, and the remaining lifting control zones as follower control zones; the lifting control system configured in the core control zone as the main control system, and the lifting control system configured in the follower control zones as the follower control system; the main control system determines the lifting control logic strategy in the core control zone based on the displacement status in the core control zone; the follower control system simultaneously determines the lifting control logic strategy in the follower control zones based on both the displacement status in the core control zone and the displacement status in the follower control zones.

[0020] A building lifting control method with multi-system extended linkage without communication is disclosed. The building lifting control method includes: S1, dividing the building to be lifted into multiple lifting control zones, and configuring a lifting control system for each lifting control zone; for all lifting control zones, selecting one lifting control zone as the core control zone, and the remaining lifting control zones as follower control zones; the lifting control system configured in the core control zone serves as the main control system, and the lifting control system configured in the follower control zones serves as the follower control system; S2, determining a certain number of displacement data acquisition points as general data acquisition points for each lifting control zone, configuring a general point displacement sensor for each general data acquisition point, and connecting the detection signals of the general point displacement sensors to their respective lifting control systems; S3, further determining several displacement data acquisition points as key points for the core control zone. Each key data acquisition point is equipped with a key point displacement sensor; the detection signals of the key point displacement sensors are connected to all lifting control systems; S4, during the building lifting operation, within the core control area, the main control system collects displacement data at each displacement data acquisition point within the core control area through various displacement sensors, and then determines the lifting control logic strategy within the core control area based on the displacement data collected within the core control area; within each follower control area, the follower control system collects displacement data at each general data acquisition point within its jurisdiction through general point displacement sensors, and also collects displacement data at each key data acquisition point within the core control area through key point displacement sensors, and then determines the lifting control logic strategy within its own follower control area based on the general point displacement data and the key point displacement data.

[0021] Furthermore, the method for determining the lifting control logic strategy within the core control area based on displacement data collected within the core control area specifically includes: presetting the target displacement of the control point within the core control area to x1mm, and the allowable displacement deviation between each control point within the core control area to ±x2mm; collecting displacement data of general data collection points and key data collection points within the area in real time; when the displacement of a certain control point deviates from the average displacement of all data collection points within the core control area by more than x3mm, outputting a switch command to control the corresponding jack to lift; when the deviation exceeds x4mm, outputting a switch command to control the corresponding jack to unload; repeating this control process until the overall lifting amount reaches the target displacement and then stops; x1, x2, x3, and x4 are settable values.

[0022] Furthermore, the lifting control logic strategy based on general point displacement data and key point displacement data to determine the lifting control within its own following control area specifically includes: presetting the allowable displacement deviation between each control point in the following control area to x5mm; the following control system collects displacement data of general data acquisition points in its own control area and displacement data of key data acquisition points in the core control area in real time; when the displacement of a data acquisition point at a certain control point in the following control area deviates from the average displacement of key data acquisition points in the core control area by more than x6mm, a switch command is output to control the corresponding jack to lift; when the deviation exceeds x7mm, a switch command is output to control the corresponding jack to unload; when the deviation is between -x8mm and +x8mm, a switch command is output to control the corresponding jack to stop moving; x5, x6, x7, and x8 are settable values.

[0023] Furthermore, the lifting control system includes a jack, a high-pressure oil pump, a displacement sensor, an inclinometer, and a laser rangefinder.

[0024] Furthermore, the principle for determining the general data acquisition points is to set up a general data acquisition point near each lifting control point.

[0025] Furthermore, the principle for determining the key data collection points is the key location within the core control area.

[0026] Furthermore, the detection signals of the general point displacement sensors are all connected to the lifting control system configured in their respective lifting control areas; the detection signals of the key point displacement sensors configured in the core control area are not only connected to the lifting control system configured in their respective core control areas, but also connected to the lifting control systems configured in other follow control areas. Each follow control system can acquire displacement data at each key data acquisition point in the core control area.

[0027] A building lifting control terminal with non-communication multi-system extended linkage, wherein the building lifting control terminal is equipped with a computer program capable of implementing the building lifting control method described above.

[0028] The main advantages of the building lifting control method and terminal for multi-system extended linkage without communication of the present invention compared with the prior art are as follows:

[0029] For the building to be lifted, the system is divided into a core control area and a follow-up control area. Within the core control area, the lifting control system implements the normal lifting control logic strategy. Within the follow-up control area, the lifting control system determines the lifting control logic strategy based on the displacement conditions in both the core and follow-up control areas. In this way, it is not necessary to connect all the lifting control systems together via electrical communication to achieve coordinated control of multiple lifting control systems, thereby completing the lifting operation of large buildings. The technical difficulty of the operation is relatively low and it is easy to implement. Attached Figure Description

[0030] Figure 1 This is a schematic diagram illustrating the building lifting control method of the present invention with non-communication multi-system extended linkage in a specific case. Detailed Implementation

[0031] The following provides further details on specific embodiments of the present invention:

[0032] This embodiment provides a building lifting control method with non-communication multi-system extended linkage. This building lifting control method can perfectly realize the linkage control of multiple lifting control systems to complete the lifting operation of large buildings. Moreover, the technical difficulty of implementation is low and easy to achieve.

[0033] Specifically, the building lifting control method of this embodiment includes the following steps S1 to S4.

[0034] S1, for the building to be lifted, divide it into multiple lifting control zones, and configure a corresponding lifting control system for each lifting control zone;

[0035] Each lifting control zone is equipped with a lifting control system that maintains a certain degree of independence.

[0036] Those skilled in the art will understand that the lifting control system mentioned herein refers to a complete set of equipment systems used to carry out building lifting operations, which typically includes jacks, high-pressure oil pumps, displacement sensors, inclinometers, laser rangefinders, and so on.

[0037] It should be noted that, in the process of dividing the lifting control area and configuring the lifting control system, the number of lifting control points required is determined based on the project requirements and the maximum number of lifting control points for a single lifting control system. The lifting control points are then divided into a corresponding number of lifting control areas, with each lifting control system corresponding to one lifting control area.

[0038] Then, for all the defined lifting control areas, one lifting control area is selected as the core control area, and the other lifting control areas are designated as follower control areas. The lifting control system configured for the core control area is called the main control system, while the lifting control system configured for the follower control areas is called the follower control system.

[0039] It should be noted that the core control area should be the area that faces greater risks in the entire building lifting operation and requires key attention; while the follow control area is the area that faces relatively less risks in the entire building lifting operation and can be of secondary concern.

[0040] Those skilled in the art will understand that it is necessary to determine the lifting control points within the lifting control area and to install and configure corresponding jacks for each lifting control point.

[0041] S2. For each lifting control area (including the core control area and the following control area), a certain number of displacement data acquisition points are determined as general data acquisition points. Corresponding displacement sensors are configured for each determined general data acquisition point to detect the displacement data at the general data acquisition point. For ease of description, the displacement sensor configured at the general data acquisition point is defined as "general point displacement sensor".

[0042] The principle for determining general data collection points is to set up a general data collection point near each lifting control point.

[0043] S3. For the core control area, determine several displacement data acquisition points as key data acquisition points; configure a corresponding displacement sensor for each determined key data acquisition point to detect the displacement data at the key data acquisition point.

[0044] For ease of description, the displacement sensors configured at key data acquisition points will be defined as "key point displacement sensors".

[0045] The principle for determining key data collection points is as follows: Key locations within the core control area are typically the center of a polygon formed by multiple elevation control points, or locations within structurally sensitive areas of buildings or structures. The specific key data collection points can be determined based on the specific construction conditions of the project.

[0046] Within the core control area, the number of key data collection points can be more sparse than that of general data collection points.

[0047] It is important to note that, regardless of whether it is the core control area or the follow control area, the detection signals of the general point displacement sensors configured therein are all connected to the lifting control system (i.e., the main control system or the follow control system) configured in their respective lifting control areas.

[0048] The displacement sensors configured at key points in the core control area have their detection signals connected not only to the lifting control system (i.e., the main control system) configured in the core control area, but also to the lifting control systems (i.e., the follow control systems) configured in other follow control areas. In this way, each follow control system can also obtain displacement data at each key data acquisition point in the core control area.

[0049] S4. During the building lifting operation, within the core control area, the configured lifting control system (main control system) collects displacement data at various displacement data collection points (including key data collection points and general data collection points) within the core control area through various displacement sensors (including key point displacement sensors and general point displacement sensors). Then, it calculates the deviation values ​​between all collected displacement data and preset target displacement parameters, and determines and outputs control commands based on control thresholds (such as the allowable range of displacement deviation) to control its own actuator actions (such as controlling the jack to lift or unload).

[0050] Within each follow-control area

[0051] The configured lifting control system (following control system) collects displacement data at each displacement data collection point (general data collection point) within its jurisdiction through various displacement sensors (general point displacement sensors), and this displacement data serves as general point displacement data.

[0052] at the same time,

[0053] The configured lifting control system (following control system) also collects displacement data at each key data acquisition point in the core control area through key point displacement sensors. This displacement data serves as the key point displacement data. Then, the deviation between the "displacement data at general data acquisition points" and the "displacement data at key data acquisition points" is calculated. Combined with control thresholds (such as the allowable range of displacement deviation), control commands are determined and output to control the actions of its own actuators (such as controlling the jack to lift or unload).

[0054] In this embodiment, a building lifting control terminal is also provided for the above-described building lifting control method. The building lifting control terminal is equipped with a computer program that can implement the above-described building lifting control method.

[0055] See Figure 1 Here is a specific example:

[0056] 1. Project Background

[0057] Suppose an existing building requires foundation lifting due to ground settlement, with a total lifting amount of 100mm, and a total of 20 control points are needed (in... Figure 1 (Using a circular symbol to indicate) Collaborative lifting operations.

[0058] The control points are driven by jacks. The selected single control system supports a maximum of 8 control points, so 3 sets of control systems need to be used for joint control (1 main control system + 2 follower control systems).

[0059] 2. Implementation Steps

[0060] 1) Divide the control system control areas: Divide the top surface of the building foundation into 3 control areas, of which the core control area (e.g., Figure 1 The area indicated by the middle arrow A contains 8 control points, following the control area (such as...). Figure 1 The area indicated by the middle arrows B1 and B2 contains 6 control points, and the follow-up control area contains 6 control points. The control system covering the core settlement area of ​​the building is selected as the main control system, and the other two are follow-up control systems. The main control system regulates the core control area, and the two follow-up control systems regulate the two follow-up control areas respectively.

[0061] 2) Set up general data collection points (in Figure 1 (Used as a triangle in the diagram): Displacement sensors are placed near each control point, with a total of 20 general data acquisition points. The core control area contains 8 general data acquisition points, which are connected to the main control system; each follower control area contains 6 general data acquisition points, all of which are connected to the follower control system.

[0062] 3) Deploy key data collection points (in Figure 1 (Represented by a diamond symbol): Four key locations are selected in the core control area, and a total of four key data acquisition points are set up. The sensors of the four key data acquisition points are all connected to three sets of control systems.

[0063] 4) Main control system control logic settings: The target displacement of the 8 control points in the core control area is preset to 100mm, and the allowable displacement deviation between each control point in the core control area is ±1mm; the displacement data of general data acquisition points and key data acquisition points in the area are collected in real time; when the displacement of a certain control point deviates from the average displacement of all acquisition points in the core control area by more than -1mm, a switch command is output to control the corresponding jack to lift; when the deviation exceeds +1mm, a switch command is output to control the corresponding jack to unload; this control process is repeated until the overall lifting amount reaches the target displacement and then stops.

[0064] 5) Follow-up control system control logic settings: The preset allowable displacement deviation between each control point in the follow-up control area is ±1mm; the follow-up control system collects displacement data of general data acquisition points in its own control area and displacement data of key data acquisition points in the core control area in real time; when the displacement of a data acquisition point at a certain control point in the follow-up control area deviates from the average displacement of the four key data acquisition points in the core control area by more than -1mm, a switch command is output to control the corresponding jack to lift; when the deviation exceeds +1mm, a switch command is output to control the corresponding jack to unload; when the deviation is between -1mm and +1mm, a switch command is output to control the corresponding jack to stop moving; this control process is repeated.

[0065] 6) System Operation and Coordination: During construction, the main control system prioritizes responding to displacement changes in the core area, and the follow control system dynamically adjusts its actions based on displacement data from key data collection points in the core control area. When a jack in the core control area is lifted, the follow control system collects displacement changes in the core control area and synchronously fine-tunes the actions of its own jacks, ensuring that the entire system remains in a coordinated state at all times.

[0066] This case demonstrates how three control systems without communication capabilities can achieve coordinated control of 20 control points.

[0067] The main advantages of the building lifting control method of this embodiment are:

[0068] 1) In the building lifting control method of this embodiment, the building to be lifted is divided into a core control area and a follow-up control area. In the core control area, the lifting control system implements the normal lifting control logic strategy. In the follow-up control area, the lifting control system determines the lifting control logic strategy in the follow-up control area based on the displacement status in both the core control area and the follow-up control area. In this way, it is not necessary to "connect all the lifting control systems together through electrical communication" to achieve the linkage control of multiple lifting control systems, thereby completing the lifting operation of large buildings. The technical difficulty of the operation is low and it is easy to implement.

[0069] In addition, the building lifting control method of this embodiment has other advantages, as follows:

[0070] 2) Reduced costs: No need to develop or integrate inter-system communication modules, saving costs on hardware procurement, software development and compatibility debugging, reducing costs by more than 30% compared to traditional linkage solutions with communication functions;

[0071] 3) Flexible expansion: The number of follow control systems can be flexibly increased according to engineering needs. New systems only need to be connected to the sensing network of key data acquisition points to be integrated into the linkage system without modifying the core program of the original system.

[0072] 4) Improved reliability: Avoid system loss of control due to communication failures. The control logic relies on locally collected data, so there is no risk of single point of failure in the system.

[0073] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
