In the related art, the working state of the hook claw supporting system of the construction integrated platform is mainly detected by manual observation and experience judgment. However, this method has the following defects: 1. Subjectivity: manual observation is easily affected by personal subjective consciousness and experience, resulting in inconsistency and inaccuracy of the judgment result; 2. Real-time: manual observation needs to consume a large amount of time and human resources, and cannot monitor the working state of the hook claw supporting system in real time; 3. Reliability: manual observation is easily disturbed by environmental factors such as light and field of view, thereby affecting the reliability of the judgment result.

[0003] However, in the construction integrated platform scene, the platform is loaded with hundreds of tons, and if a spring or other mechanical structure is used to detect the state of the hook claw, the detection device will be damaged due to excessive pressure. If a pressure sensor is used for detection, the construction site environment is complex, the supporting points hooked by the hook claw are numerous, wiring is difficult and is easily damaged, and other accidents may occur during the lifting operation, thereby affecting the detection accuracy.

[0005] Therefore, there is an urgent need for a detection device and method that can accurately, timely and reliably detect the working state of the hook claw supporting system of the construction integrated platform, so as to improve the construction safety and work efficiency. SUMMARY

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] The term "comprising" and variations thereof as used in this document encompass the presence of stated features, integers, steps or components but not the exclusion of others. The term "based on" is not exclusive. The term "one embodiment" means "at least one embodiment". The term "another embodiment" means "at least one additional embodiment". The term "some embodiments" means "at least some embodiments". Related definitions are given throughout the description.

[0031] In the related art, the construction integrated platform is mainly used for super high-rise building construction, and is fixed to the surface of the concrete wall by the hook claw support system, and is lifted by the jacking system. In the related art, the working state of the hook claw support system of the construction integrated platform is mainly detected by manual observation and experience judgment. This method has the following defects: 1. Subjectivity: manual observation is easily affected by personal subjective consciousness and experience, resulting in inconsistency and inaccuracy of the judgment result; 2. Real-time: manual observation requires a lot of time and human resources, and cannot monitor the working state of the hook claw support system in real time; 3. Reliability: manual observation is easily disturbed by environmental factors such as light and field of view, thereby affecting the reliability of the judgment result.

[0032] However, in the construction integrated platform scene, the platform is loaded with hundreds of tons, and if the hook claw state is detected by a mechanical structure such as a spring, the detection device will inevitably be damaged due to excessive pressure. The use of a pressure sensor for detection is difficult and easily damaged due to the complex construction site environment and the large number of support points hooked by the hook claw. During the jacking operation, other unexpected situations may occur, thereby affecting the detection accuracy.

[0033] Therefore, if the working state of the hook claw support system is detected by a mechanical method, the device is prone to damage and the cost is high. If the working state of the hook claw support system is detected by manual inspection, multiple people need to work in dangerous conditions, and false detection may occur due to subjective and objective reasons such as parallax, illumination and obstruction.

[0034] Therefore, it is urgent to provide a detection device and method capable of accurately, real-timely and reliably detecting the working state of the hook support system of the construction integrated platform, so as to improve the construction safety and working efficiency.

[0035] In order to solve the technical problems in the related art, an embodiment of the present application provides a detection device for working state of a support structure, please refer to Figure 1 , Figure 1 is a structural schematic diagram of the detection device for working state of a support structure provided by the embodiment of the present application, as Figure 1 shown, the detection device for working state of a support structure provided by the embodiment of the present application comprises an image acquisition device 4, a photographed subject 5 and an analysis module (not shown in the figure);

[0036] Among them, the image acquisition device 4 and the photographed subject 5 are arranged on the construction platform or the jacking system, and the positions of the support structure 2 to be detected, the image acquisition device 4 and the photographed subject 5 are kept on a straight line in the height direction, the support structure 2 is a support structure 2 that can be upwardly overturned and horizontally fixed; the support structure 2 is located between the image acquisition device 4 and the photographed subject 5, and the camera of the image acquisition device 4 faces the photographed subject 5; one side of the photographed subject 5 facing the image acquisition device 4 direction is provided with at least two different marks, the image acquisition device 4 is used for collecting mark images of marks on the photographed subject 5 that are not blocked by the support structure 2 in different working states of the support structure 2, and sending the mark images to the analysis module, so that the analysis module determines the target working state of the support structure 2 according to the types of marks in the mark images.

[0037] It should be noted that the relative positions between the image acquisition device 4 and the photographed subject 5 provided by the embodiment are not limited to the position relationship that the image acquisition device 4 is above and the photographed subject 5 is below as Figure 1 described, but also can be the position relationship that the photographed subject 5 is above and the image acquisition device 4 is below, as long as the positions of the support structure 2 to be detected, the image acquisition device 4 and the photographed subject 5 can be kept on a straight line in the height direction, which is not limited here.

[0038] In the embodiment, please continue to refer to Figure 1The image acquisition device 4 and the object to be photographed 5 provided in this embodiment can be installed on a construction platform or a lifting system, preferably on the support column 3 of the construction platform or the hydraulic cylinder bracket of the lifting system. In this embodiment, one end of the support structure 2 is fixed to the concrete wall via a wall-mounted support 11, while the other end can be freely rotated. The support column 3 or the hydraulic cylinder bracket is equipped with multiple load-bearing rods, which can be hung on the support structure 2.

[0039] Specifically, when the lifting system drives the support column 3 to rise, the load-bearing rod of the support column 3 pushes the support structure 2 to flip towards the side closer to the concrete wall, making space for the support column 3 to move upward. Then, the support structure 2 naturally falls down under gravity, so that the load-bearing rod hangs on the support structure 2. When the lifting system drives the hydraulic cylinder bracket to rise, the lifting process is the same as the process of the lifting system driving the support column 3, and will not be described again here.

[0040] like Figure 1 As shown, when setting up the image acquisition device 4 and the target object 5, the support structure 2 is positioned between the image acquisition device 4 and the target object 5, and the camera of the image acquisition device 4 is positioned directly facing the target object 5. This allows the image acquisition device 4 to capture images of the target object 5 in the direction indicated by the arrow in the figure. Based on the type of identification in the captured image, the current target working state of the support structure 2 can be determined. This achieves the purpose of accurately, in real-time, and reliably detecting the working state of the support structure 2 on the construction integration platform. It also facilitates the timely issuance of early warning information when the support structure 2 is detected to be in a potentially hazardous working state during the jacking operation of the construction platform or the jacking system. This reduces the manpower required for jacking operation inspections and effectively avoids the occurrence of safety hazards.

[0041] In some embodiments, in order to accurately identify different working states of the support structure 2, the identifier provided in this embodiment of the invention may include two different first color identifiers and second color identifiers. The working states of the support structure 2 include a first working state of flipping upwards, a second working state of falling under its own weight, and a third working state of bearing load. The first color identifier and the second color identifier are set according to a preset positional relationship. The preset positional relationship is that when the support structure 2 is in the first working state, the image acquisition device 4 can simultaneously acquire the first color identifier and the second color identifier on the photographed object 5. When the support structure 2 is in the second working state, the image acquisition device 4 can acquire the second color identifier on the photographed object 5 but cannot acquire the first color identifier. When the support structure 2 is in the third working state, the image acquisition device 4 cannot acquire the first color identifier and the second color identifier on the photographed object 5.

[0042] Specifically, the first color mark can be arranged at a position close to the fixed end of the support structure 2, and the second color mark can be arranged at a position away from the fixed end of the support structure 2. Therefore, according to the first working state, the second working state and the third working state of the support structure 2, when the first color mark and the second color mark are detected in the mark image at the same time, it can be determined that the support structure 2 is in the first working state of being turned up; when only the second color mark is detected in the mark image, it can be determined that the support structure 2 is in the second working state of being turned down by its own gravity; and when neither the first color mark nor the second color mark is detected in the mark image, it can be determined that the support structure 2 is in the third working state of being supported. In this way, the target working state of the support structure 2 can be accurately identified.

[0043] It should be noted that the first color mark and the second color mark provided in the embodiment can be selected to be different and easy to identify, so as to avoid misjudgment and affect the detection accuracy of the working state of the support structure 2.

[0044] As an optional embodiment, the image acquisition device 4 provided in the embodiment can be an industrial camera, and the image acquisition device 4 can also be other high-definition cameras, as long as the clarity of the acquired mark image can be ensured, and the specific limitation is not made here. The support structure 2 provided in the embodiment can be a hook structure, or other structure that can be turned over and can provide support force in a horizontal state, and the specific limitation is not made here.

[0045] In some embodiments, the photographed subject 5 provided in the embodiment can be a color plate, and the color plate has a first color block of the first color mark and a second color block of the second color mark coated according to the preset position relationship.

[0046] In other embodiments, the photographed subject 5 provided in the embodiment can be a display device, and the display device has a first color block of the first color mark and a second color block of the second color mark displayed according to the preset position relationship.

[0047] It should be noted that the colors of the first color block and the second color block provided in the embodiment can be selected to be different from the colors of the surrounding environment, so as to avoid misjudgment and affect the detection accuracy of the working state of the support structure 2.

[0048] The display device can dynamically adjust the colors of the first color block and the second color block relative to the color palette, so that the colors of the first color block and the second color block are greatly different from the colors of the surrounding environment, thereby being more suitable for different environments and effectively improving the detection accuracy of the working state of the support structure 2.

[0049] Meanwhile, the display device provided by the embodiment can also dynamically adjust the position of the junction of the first color block and the second color block to adapt to the position at which the support structure 2 normally falls by gravity, that is, when the support structure 2 is in the second working state, the support structure 2 can just block the first color block and not block the second color block.

[0050] To determine the position of the junction of the first color block and the second color block, please refer to Figure 2 , Figure 2 is a structural schematic diagram of the support structure in different working states provided by the embodiment, as shown in Figure 2 , if the support structure 2 normally falls by gravity as state ②, the position of the junction of the first color block a and the second color block b is point A in the figure; if the support structure 2 normally falls by gravity while being more inclined to state ①, that is, the support structure 2 normally falls by gravity with an angle smaller than the angle corresponding to state ②, the position of the junction needs to be moved to the right, that is, the area of the first color block a is increased and the area of the second color block b is decreased. Specifically, the proportion of the two color blocks of each support structure 2 can also be set according to this principle to eliminate installation deviation or part deviation, that is, when the support structure 2 normally falls by gravity, the position of the junction is adjusted so that the image acquisition device 4 only detects the second color block, at this time, the position of the junction of the first color block and the second color block can be determined, thereby facilitating accurate detection of the working state of the support structure 2 during the jacking operation of the construction platform or the jacking system.

[0051] In addition, the embodiment can also determine the degree to which the support structure 2 falls according to the sizes of the first color block and the second color block. As shown in Figure 2 , the smaller the length of the second color block b is, the greater the degree to which the support structure 2 falls, at this time, the length of the second color block b can be associated with the degree to which the support structure 2 falls, thereby accurately detecting the degree to which the support structure 2 falls by detecting the length of the second color block b during the jacking operation of the construction platform or the jacking system.

[0052] In the embodiment of the present application, in order to ensure that the image acquisition device 4 can only acquire the second color mark on the photographed subject 5 and cannot acquire the first color mark when the support structure 2 is in the second working state, the detection device for the working state of the support structure provided in the embodiment further comprises a limiting structure (not shown in the figure), which is arranged on the support structure 2 and is used to enable the image acquisition device 4 to acquire the first color mark and cannot acquire the second color mark when the support structure 2 is in the second working state.

[0053] Optionally, the limiting structure provided in the embodiment can be a limiting spring. Specifically, one end of the limiting spring is connected to the wall-attached support 1, and the other end is connected to the movable end of the support structure 2. When the support structure 2 normally falls down by gravity, the elastic force of the limiting spring is zero. In the embodiment, the limiting spring is arranged mainly to enable the support structure 2 to always block the first color mark and not block the second color mark when the support structure 2 is in the second working state, so that the misjudgment can be effectively avoided, and the installation deviation on site is reduced. At the same time, the limiting spring can also avoid the position deviation of the support structure 2 when it normally falls down after long-term use, so as to affect the accuracy of detection.

[0054] In another optional embodiment, the detection device for the working state of the support structure provided in the embodiment further comprises a warning module (not shown in the figure), which is connected to the analysis module and is used to issue a warning information when the support structure 2 is in a dangerous working state during the jacking operation of the construction platform or the jacking system. In this way, during the jacking process of the oil cylinder, the three working states of the support structure 2 of the construction integrated platform are detected, and when a working state that poses a danger to the jacking operation appears, a warning information can be timely issued through the warning module, so as to reduce the manpower required for the inspection of the jacking operation and effectively avoid the occurrence of safety hazards.

[0055] In summary, the embodiment of the present application provides a detection device for the working state of a support structure. The positions of the support structure 2 to be detected, the image acquisition device 4 and the photographed subject 5 are kept on a straight line in the height direction, the support structure 2 is located between the image acquisition device 4 and the photographed subject 5, and the camera of the image acquisition device 4 faces the photographed subject 5, so that the image acquisition device 4 can acquire the mark image of the mark on the photographed subject 5 that is not blocked by the support structure 2 in different working states of the support structure 2, and send the mark image to the analysis module. The analysis module determines the target working state of the support structure 2 according to the type of the mark in the mark image, so that the working state of the support structure 2 on the construction integrated platform can be accurately, timely and reliably detected.

[0056] To solve the same technical problem, the embodiment of the present application also provides a detection method of the detection device of the working state of the support structure, and specifically, please refer to Figure 1 and Figure 3 , Figure 3 is a flowchart of the detection method of the detection device of the working state of the support structure provided by the embodiment of the present application, as shown in Figure 1 and Figure 3 , the detection method of the detection device of the working state of the support structure provided by the embodiment comprises the following steps:

[0057] Step S101, the image acquisition device 4 and the photographed object 5 are arranged in the height direction of the construction platform or the jacking system, so that the positions of the support structure 2 to be detected, the image acquisition device 4 and the photographed object 5 are kept on a straight line in the height direction, the support structure 2 is located between the image acquisition device 4 and the photographed object 5, and the camera of the image acquisition device 4 directly faces the photographed object 5.

[0058] Step S102, the mark arranged on the photographed object 5 is acquired by the image acquisition device 4 to obtain a mark image.

[0059] Step S103, in the case that the first mark and the second mark exist in the mark image at the same time, it is determined that the support structure 2 is in the first working state of being turned up.

[0060] Step S104, in the case that only the second mark exists in the mark image, it is determined that the support structure 2 is in the second working state of being laid down by its own gravity.

[0061] Step S105, in the case that neither the first mark nor the second mark exists in the mark image, it is determined that the support structure 2 is in the third working state of being supported.

[0062] Specifically, as shown in Figure 1 , the arrow is the shooting angle of the image acquisition device 4, the support structure 2 should be in the third working state of being supported at the beginning, and the target object (the mark arranged on the photographed object 5) in the field of view of the image acquisition device 4 is blocked. Then, at the beginning of the jacking process, the image detection program can be triggered to start through the jacking cylinder control signal.

[0063] With the advancement of the jacking process, the support structure 2 starts to be jacked up and turned up when the support structure 2 starts to contact the supporting rod, and the mark arranged on the photographed object 5 gradually becomes visible in the field of view of the image acquisition device 4. Specifically, the second mark is visible in the field of view of the image acquisition device 4 before the first mark.

[0064] When the support column 3 is jacked to the highest point of this jacking operation, at this time the support structure 2 should be in the second working state of falling down under its own gravity, at this time the first mark should be invisible in the field of view of the image acquisition device 4, and the second mark is visible, if the first mark is not completely blocked by the support structure 2, that is, the support structure 2 is in the first working state of upwardly turning over at this time, it indicates that the support structure 2 is not in the falling down state, then it can be judged that the working state of the support structure 2 is abnormal, and the maintenance personnel should be notified to troubleshoot the problem, so that the support structure 2 is in the falling down state, that is, in the second working state of falling down under its own gravity.

[0065] Therefore, by using the detection method of the detection device for the working state of the support structure provided by the embodiment of the present application, the working state of the support structure 2 can be accurately identified according to the detected color block, the problems of complex field conditions, large demand for manpower, dangerous operation, high deployment cost and difficulty in implementation of the general physical sensor scheme in the detection task of the working state of the construction integrated platform support structure 2 are solved, the technical blank of intelligent detection of the working state of the support structure 2 is filled, the manpower cost is effectively saved, and the detection efficiency of the working state of the support structure 2 is improved.

[0066] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
