Description

Technical Field

[0001] The present invention relates to the field of construction technology, and in particular to a detection device and a detection method for a working state of a supporting structure. Background Art

[0002] The construction integrated platform is mainly used in the construction of super high-rise buildings. It is fixed to the surface of the concrete wall by the hook support system and lifted by the lifting system. In the related technology, the detection of the working status of the hook support system of the construction integrated platform mainly relies on 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 results; 2. Real-time: Manual observation requires a lot of time and human resources, and it is impossible to monitor the working status of the hook support system in real time; 3. Reliability: Manual observation is easily affected by environmental factors, such as light, field of view, etc., which affects the reliability of the judgment results.

[0003] In the construction integrated platform scenario, since the platform load weighs hundreds of tons, if the hook status is detected through mechanical structures such as springs, the detection device will inevitably be damaged due to excessive pressure. If pressure sensors are used for detection, the construction site environment is complex and there are many support points hooked by the hook, which makes wiring difficult and easy to be damaged. Other unexpected situations are likely to occur during the jacking operation, thus affecting the detection accuracy.

[0004] Therefore, if a mechanical method is used to detect the working status of the hook support system, there are problems such as easy damage to the device and high cost; if a manual inspection method is used to detect the working status of the hook support system, multiple people are required to work under dangerous conditions, and false detection may occur due to subjective and objective reasons such as parallax, lighting, and occlusion.

[0005] Therefore, there is an urgent need for a detection device and method that can accurately, real-time and reliably detect the working status of the hook support system of the construction integrated platform to improve construction safety and work efficiency. Summary of the invention

[0006] The purpose of the embodiments of the present invention is to provide a device and method for detecting the working state of a supporting structure, so as to solve at least one technical problem existing in the above-mentioned background technology.

[0007] In a first aspect, to achieve the above-mentioned purpose, an embodiment of the present invention provides a device for detecting the working status of a supporting structure, comprising:

[0008] In some embodiments, the identification includes two different first color identifications and second color identifications, and the working state of the support structure includes a first working state of flipping upward, a second working state of falling down under its own gravity, and a third working state of bearing load;

[0009] The first color identification and the second color identification are arranged according to a preset position relationship, and the preset position relationship is that when the supporting structure is in the first working state, the image acquisition device can simultaneously acquire the first color identification and the second color identification on the photographed object; when the supporting structure is in the second working state, the image acquisition device can acquire the second color identification on the photographed object but cannot acquire the first color identification; when the supporting structure is in the third working state, the image acquisition device cannot acquire the first color identification and the second color identification on the photographed object.

[0010] In some embodiments, the photographed object is a color plate, and a first color block with the first color identification and a second color block with the second color identification are coated on the color plate according to the preset position relationship.

[0012] In some embodiments, the image acquisition device is an industrial camera.

[0013] In some embodiments, the support structure is a hook structure.

[0014] In some embodiments, the detection device for the working status of the support structure also includes a limiting structure, which is arranged on the support structure. The limiting structure is used to enable the image acquisition device to capture the first color mark but fail to capture the second color mark when the support structure is in the second working state.

[0015] In some embodiments, the limiting structure is a limiting spring.

[0016] In some embodiments, the detection device for the working status of the supporting structure also includes an early warning module, which is connected to the analysis module. The early warning module is used to issue an early warning message when it receives a message that the supporting structure is in a working status with hidden danger during the jacking operation of the construction platform or the jacking system.

[0017] In a second aspect, in order to achieve the same purpose, an embodiment of the present invention further provides a method for detecting a device for detecting a working state of a support structure, comprising the following steps:

[0018] An image acquisition device and a photographed object are arranged in the height direction of the construction platform or the jacking system, so that the positions of the support structure to be detected, the image acquisition device and the photographed object are kept in a straight line in the height direction, and the support structure is located between the image acquisition device and the photographed object, and the camera of the image acquisition device faces the photographed object;

[0019] The image acquisition device is used to acquire a mark set on the photographed object to obtain a mark image;

[0020] In a case where the first mark and the second mark exist in the mark image at the same time, determining that the support structure is in a first working state flipped upward;

[0021] In the case where only the second mark exists in the mark image, determining that the support structure is in the second working state of falling down due to its own gravity;

[0022] When the first mark or the second mark does not exist in the mark image, it is determined that the supporting structure is in the third working state when bearing force.

[0023] The embodiment of the present invention provides a detection device and a detection method for the working status of a support structure.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The term "including" and its variations used herein are open inclusions, i.e., "including but not limited to". The term "based on" means "based at least in part on". 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". The relevant definitions of other terms will be given in the following description.

[0031] In the related art, the construction integrated platform is mainly used in the construction of super high-rise buildings. It is fixed on the surface of the concrete wall by the hook support system and lifted by the lifting system. In the related art, the detection of the working status of the hook support system of the construction integrated platform mainly relies on 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 results; 2. Real-time: Manual observation requires a lot of time and human resources, and it is impossible to monitor the working status of the hook support system in real time; 3. Reliability: Manual observation is easily affected by environmental factors, such as light, field of view, etc., which affects the reliability of the judgment results.

[0032] In the construction integrated platform scenario, since the platform load weighs hundreds of tons, if the hook status is detected through mechanical structures such as springs, the detection device will inevitably be damaged due to excessive pressure. If pressure sensors are used for detection, the construction site environment is complex and there are many support points hooked by the hook, which makes wiring difficult and easy to be damaged. Other unexpected situations are likely to occur during the jacking operation, thus affecting the detection accuracy.

[0033] Therefore, if a mechanical method is used to detect the working status of the hook support system, there are problems such as easy damage to the device and high cost; if a manual inspection method is used to detect the working status of the hook support system, multiple people are required to work under dangerous conditions, and false detection may occur due to subjective and objective reasons such as parallax, lighting, and occlusion.

[0034] Therefore, there is an urgent need for a detection device and method that can accurately, real-time and reliably detect the working status of the hook support system of the construction integrated platform to improve construction safety and work efficiency.

[0035] In order to solve the technical problems existing in the related art, this embodiment provides a detection device for the working state of a support structure, see Figure 1 , Figure 1 is a structural schematic diagram of a device for detecting the working state of a support structure provided by an embodiment of the present invention, such as Figure 1 As shown, the apparatus for detecting the working state of the support structure provided in the embodiment of the present invention comprises: an image acquisition device 4, a photographed target object 5 and an analysis module (not shown in the figure);

[0036] Wherein, the image acquisition device 4 and the photographed target 5 are arranged on a construction platform or a jacking system, and the positions of the support structure 2 to be detected, the image acquisition device 4 and the photographed target 5 are maintained in a straight line in the height direction, and the support structure 2 is a support structure 2 that can be flipped upward and fixed horizontally; the support structure 2 is located between the image acquisition device 4 and the photographed target 5, and the camera of the image acquisition device 4 is facing the photographed target 5; at least two different identifications are provided on one side of the photographed target 5 facing the image acquisition device 4, and the image acquisition device 4 is used to collect the identification on the photographed target 5 that is not blocked by the support structure 2 under different working states of the support structure 2 to obtain an identification image, and send the identification image to the analysis module, so that the analysis module can determine the current target working state of the support structure 2 according to the type of identification in the identification image.

[0037] It should be noted that the relative position between the image acquisition device 4 and the photographed object 5 provided in this embodiment is not limited to the following. Figure 1 The positional relationship in which the image acquisition device 4 is above and the photographed target 5 is below can also be a positional relationship in which the photographed target 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 target 5 can be kept in a straight line in the height direction, and no specific limitation is made here.

[0038] In this example, please continue to refer to Figure 1The image acquisition device 4 and the photographed object 5 provided in this embodiment can be set on the construction platform or the jacking system, preferably on the support column 3 of the construction platform or the cylinder bracket of the jacking system. Among them, one end of the support structure 2 provided in this embodiment is fixed to the concrete wall through the wall support 11, and the other end can be turned freely. The support column 3 or the cylinder bracket is provided with a plurality of bearing rods, and the support column 3 or the cylinder bracket can be hung on the support structure 2 through the bearing rods.

[0039] Specifically, when the jacking system drives the support column 3 to jack up, the load-bearing rod of the support column 3 pushes the support structure 2 to flip toward the side close to the concrete wall, freeing up space for the support column 3 to move up, and then the support structure 2 naturally falls down by gravity, so that the load-bearing rod hangs on the support structure 2. When the jacking system drives the oil cylinder bracket to jack up, the jacking process is the same as the process of the jacking system driving the support column 3, which will not be repeated here.

[0040] like Figure 1 As shown, when setting the image acquisition device 4 and the photographed target 5, the support structure 2 is located between the image acquisition device 4 and the photographed target 5, and the camera of the image acquisition device 4 is facing the photographed target 5, so that the image acquisition device 4 captures the image of the photographed target 5 along the direction indicated by the arrow in the figure, so that the current target working state of the support structure 2 can be determined according to the type identified in the captured image, so as to achieve the purpose of accurately, real-time and reliably detecting the working state of the support structure 2 on the construction integrated platform, so that during the jacking operation of the construction platform or the jacking system, when it is detected that the support structure 2 is in a working state with hidden dangers, early warning information can be issued in time, thereby reducing the manpower input required for the jacking operation inspection, and effectively avoiding the occurrence of safety hazards.

[0041] In some embodiments, in order to accurately identify different working states of the support structure 2, the identification provided by the embodiment of the present invention may include two different first color identifications and second color identifications, and the working states of the support structure 2 include a first working state of flipping upward, a second working state of falling down under its own gravity, and a third working state when bearing force; the first color identification and the second color identification are arranged according to a preset position relationship, and the preset position relationship is that when the support structure 2 is in the first working state, the image acquisition device 4 can simultaneously capture the first color identification and the second color identification on the photographed target 5, when the support structure 2 is in the second working state, the image acquisition device 4 can capture the second color identification on the photographed target 5, and cannot capture the first color identification, and when the support structure 2 is in the third working state, the image acquisition device 4 cannot capture the first color identification and the second color identification on the photographed target 5.

[0042] Specifically, the first color identification provided in this embodiment can be set at a position close to the fixed end of the support structure 2, and the second color identification can be set at a position far from the fixed end of the support structure 2. Therefore, according to the pre-set first working state, second working state and third working state of the support structure 2, when it is detected that both the first color identification and the second color identification exist in the identification image, it can be determined that the support structure 2 is in the first working state of flipping upward; when it is detected that only the second color identification exists in the identification image, it can be determined that the support structure 2 is in the second working state of falling down under its own gravity; when it is detected that the first color identification or the second color identification does not exist in the identification image, it can be determined that the support structure 2 is in the third working state of bearing force. In this way, the purpose of accurately identifying the current target working state of the support structure 2 can be achieved.

[0043] It should be noted that the first color identification and the second color identification provided in this embodiment can be selected to have large differences and be easy to identify, so as to avoid misjudgment, thereby affecting the detection accuracy of the working status of the support structure 2.

[0044] As an optional embodiment, the image acquisition device 4 provided in this embodiment can be an industrial camera, or other high-definition cameras, as long as the clarity of the captured identification image can be guaranteed, and no specific limitation is made here. The support structure 2 provided in this embodiment can be a hook structure, or other structures that can be flipped and can provide support force in a horizontal state, and no specific limitation is made here.

[0045] In some embodiments, the photographed target object 5 provided in this embodiment may be a color plate, on which a first color block with the first color identification and a second color block with the second color identification are coated according to the preset positional relationship.

[0046] In other embodiments, the photographed target object 5 provided in this embodiment may be a display device, on which a first color block with the first color identification and a second color block with the second color identification are displayed according to the preset positional relationship.

[0047] It should be noted that the colors of the first color block and the second color block provided in this embodiment can be selected to be colors that are greatly different from the colors of the surrounding environment to avoid misjudgment, thereby affecting the detection accuracy of the working status of the support structure 2.

[0048] Among them, relative to the color plate, the display device can dynamically adjust the colors of the first color block and the second color block so that the colors of the first color block and the second color block are significantly different from the colors of the surrounding environment, so that it can be more suitable for different environments and effectively improve the detection accuracy of the working status of the support structure 2.

[0049] At the same time, the display device provided in this embodiment can also dynamically adjust the junction position of the first color block and the second color block to adapt to the position where the support structure 2 normally falls down due to 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 but not the second color block.

[0050] To determine the intersection of the first and second color blocks, see Figure 2 , Figure 2 is a schematic diagram of the structure of the support structure provided by the embodiment of the present invention in different working states, such as Figure 2 As shown, if the support structure 2 falls down normally due to gravity, it is exactly state ②, then the junction position of the first color block a and the second color block b is point A in the figure; if the support structure 2 falls down normally due to gravity and is more inclined to state ① at the same time, that is, the angle between the support structure 2 and the horizontal when it falls down normally due to gravity is smaller than the angle corresponding to state ②, then it is necessary to move the junction position A to the right, that is, increase the area of ​​the first color block a and reduce the area of ​​the second color block b. Specifically, the ratio 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 falls down normally due to gravity, adjust the junction position so that the image acquisition device 4 only detects the second color block, and the junction position of the first color block and the second color block can be determined at this time, so that it is convenient to accurately detect the working state of the support structure 2 during the jacking operation of the construction platform or the jacking system.

[0051] In addition, this embodiment can also determine the extent of the support structure 2 falling down according to the sizes of the detected first color block and the second color block. Figure 2 As shown, if the length of the second color block b is smaller, it can be explained that the degree of collapse of the supporting structure 2 is greater. At this time, the length of the second color block b can be associated with the degree of collapse of the supporting structure 2, so that during the jacking operation of the construction platform or the jacking system, the degree of collapse of the supporting structure 2 can be accurately detected by detecting the length of the second color block b.

[0052] In the embodiment of the present invention, in order to ensure that when the support structure 2 is in the second working state, the image acquisition device 4 can just only capture the second color mark on the photographed object 5, but cannot capture the first color mark, the detection device for the working state of the support structure provided in this embodiment may also include a limiting structure (not shown in the figure), which is arranged on the support structure 2. The limiting structure is used to enable the image acquisition device 4 to capture the first color mark, but cannot capture the second color mark, when the support structure 2 is in the second working state.

[0053] Optionally, the limiting structure provided in this embodiment can be a limiting spring. Specifically, the limiting spring can be connected to the wall support 1 at one end and connected to the movable end of the supporting structure 2 at the other end. When the supporting structure 2 falls down normally due to gravity, the elastic force of the limiting spring is zero. In this embodiment, by setting the limiting spring, it is mainly to make the supporting structure 2 always happen to cover the first color mark but not the second color mark when it is in the second working state, so as to effectively avoid false detection and reduce on-site installation deviation; at the same time, by setting the limiting spring, it can also be avoided that the wear and tear due to long-term use causes the supporting structure 2 to shift from the position when it falls down normally to the position when it falls down normally, affecting the accuracy of detection.

[0054] In another optional embodiment, the detection device for the working state of the support structure provided in this embodiment may also include an early warning module (not shown in the figure), the early warning module is connected to the analysis module, and the early warning module is used to issue an early warning message when receiving a message indicating that the support structure 2 is in a working state with hidden dangers during the jacking operation of the construction platform or the jacking system. In this way, during the jacking process of the oil cylinder, by detecting the three working states of the support structure 2 of the construction integrated platform, when a working state that poses a hidden danger to the jacking operation occurs, an early warning message can be issued in time through the early warning module, thereby reducing the manpower required for the inspection of the jacking operation and effectively avoiding the occurrence of safety hazards.

[0055] In summary, an embodiment of the present invention provides a device for detecting the working status of a support structure, by maintaining the positions of the support structure 2 to be detected, the image acquisition device 4 and the photographed target 5 in a straight line in the height direction, and the support structure 2 is located between the image acquisition device 4 and the photographed target 5, and the camera of the image acquisition device 4 is facing the photographed target 5, so that the image acquisition device 4 can collect the marks on the photographed target 5 that are not blocked by the support structure 2 under different working conditions of the support structure 2 to obtain a marking image, and send the marking image to the analysis module, so that the analysis module can determine the current target working status of the support structure 2 according to the type of the mark in the marking image, so that the working status of the support structure 2 on the construction integrated platform can be accurately, real-time and reliably detected.

[0056] In order to solve the same technical problem, the embodiment of the present invention also provides a detection method of a detection device for the working state of a support structure. For details, please refer to Figure 1 and Figure 3 , Figure 3 is a flow chart of a detection method of a detection device for a supporting structure working state provided by an embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the detection method of the detection device of the working state of the support structure provided in this embodiment includes the following steps:

[0057] Step S101, set the image acquisition device 4 and the photographed target 5 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 target 5 are maintained in a straight line in the height direction, and the support structure 2 is located between the image acquisition device 4 and the photographed target 5, and the camera of the image acquisition device 4 is facing the photographed target 5.

[0058] Step S102: The image acquisition device 4 acquires the mark set on the photographed target object 5 to obtain a mark image.

[0059] Step S103 : when both the first mark and the second mark exist in the mark image, it is determined that the support structure 2 is in the first working state of flipping upward.

[0060] Step S104: when only the second mark exists in the mark image, it is determined that the support structure 2 is in the second working state of falling down due to its own gravity.

[0061] Step S105 : when there is no first mark or second mark in the mark image, determining that the support structure 2 is in the third working state of bearing force.

[0062] Specifically, Figure 1 As shown, the arrow is the shooting angle of the image acquisition device 4. Initially, the support structure 2 should be in the third working state when bearing force, at which time the target object (the mark set on the photographed target object 5) in the field of view of the image acquisition device 4 is blocked. Then, when the jacking process starts, the image detection program can be triggered by the jacking cylinder control signal.

[0063] As the lifting process progresses, the support structure 2 begins to contact the load-bearing rod, at which time the support structure 2 begins to be lifted up and flipped upward, and the mark set on the photographed target 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 supporting column 3 is lifted to the highest point of this lifting operation, the supporting 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, while the second mark is visible. If the first mark is not completely blocked by the supporting structure 2, that is, the supporting structure 2 is in the first working state of flipping upward, indicating that the supporting structure 2 is not in place, it can be judged that the working state of the supporting structure 2 is abnormal, and the maintenance personnel should be notified to investigate the problem, so that the supporting structure 2 is in a falling state, that is, in the second working state of falling down under its own gravity.

[0065] In this way, the detection method of the support structure working status detection device provided by the embodiment of the present invention can accurately identify the working status of the support structure 2 according to the detected color block, thereby solving the problems of complex on-site conditions, large manpower requirements, and dangerous operations in the detection task of the working status of the support structure 2 of the construction integrated platform, while the general physical sensor solutions have high deployment costs and are difficult to implement, thereby filling the technical gap in the intelligent detection of the working status of the support structure 2, effectively saving labor costs, and improving the detection efficiency of the working status of the support structure 2.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0067] In addition, it should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0068] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes that A and B meet at the same time. In addition, in the embodiments of the present invention, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
