[0051] It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

[0052] Referring to Figure 1 , Figure 1 The bridge-based unit assembly pressing equipment structure diagram of the hardware running environment involved in the embodiment of the present application.

[0053] As Figure 1 shown, the bridge-based unit assembly pressing equipment can include a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to realize the connection and communication between the components. The user interface 1003 can include a display screen, an input unit such as a keyboard, and can also include a standard wired interface, a wireless interface. The network interface 1004 can optionally include a standard wired interface, a wireless interface (such as a wireless fidelity (Wi-Fi) interface). The memory 1005 can be a high-speed random access memory (RAM) memory, or a stable non-volatile memory (NVM) such as a disk memory. The memory 1005 can also be a storage device independent of the aforementioned processor 1001.

[0054] Those skilled in the art can understand that Figure 1 the structure shown in the figure does not constitute a limitation on the bridge-based unit assembly pressing equipment, and can include more or fewer components than the illustrated components, or combine certain components, or different component arrangements.

[0055] As Figure 1 shown, the memory 1005 as a storage medium can include an operating system, a network communication module, a user interface module, and a bridge-based unit assembly pressing program.

[0056] In Figure 1The network interface 1004 is mainly used for data communication with a network server, and the user interface 1003 is mainly used for data interaction with a user. The processor 1001 and the memory 1005 in the bridge-based unit assembly pressing device can be arranged in the bridge-based unit assembly pressing device. The bridge-based unit assembly pressing device calls the bridge-based unit assembly pressing program stored in the memory 1005 through the processor 1001, and executes the bridge-based unit assembly pressing method provided in the embodiment of the application.

[0057] The embodiment of the application provides a bridge-based unit assembly pressing method. Figure 2 , Figure 2 FIG. 1 is a flowchart of a first embodiment of the bridge-based unit assembly pressing method.

[0058] The bridge-based unit assembly pressing method comprises the following steps:

[0059] Step S10: Obtain assembly requirement data of a longitudinal rib unit and a plate unit of a target bridge.

[0060] It should be noted that the execution subject of the embodiment is a control terminal in a bridge-based unit assembly pressing device. The bridge-based unit assembly pressing device comprises the control terminal, an image acquisition device and a pressing device. The control terminal obtains the assembly requirement data of the longitudinal rib unit and the plate unit of the target bridge, determines a pressure control value according to the assembly requirement data, performs assembly pressing on the longitudinal rib unit and the plate unit according to the pressure control value, and issues an instruction to make the image acquisition device perform image acquisition. The control terminal obtains an assembly pressing image, and determines whether the longitudinal rib unit and the plate unit are pressed according to the assembly pressing image. When it is determined that the longitudinal rib unit and the plate unit are pressed, the assembly of the longitudinal rib unit and the plate unit is completed.

[0061] It can be understood that the target bridge refers to a steel bridge that is being constructed and needs to perform assembly pressing on the longitudinal rib unit and the plate unit. The longitudinal rib unit is a longitudinal rib unit composed of a plurality of longitudinal ribs. The plate unit is a cover plate that needs to be pressed with the longitudinal rib unit. One plate unit corresponds to one longitudinal rib unit, and the longitudinal rib unit comprises a plurality of longitudinal ribs.

[0062] In the specific implementation, the assembly requirement data comprises but is not limited to an assembly structure form and an assembly requirement. The assembly structure form comprises but is not limited to a structure composition requirement of the longitudinal rib unit and the plate unit when being assembled and pressed and a spacing between the longitudinal ribs in the longitudinal rib unit. The assembly requirement comprises but is not limited to an assembly pressing degree of the longitudinal rib unit and the plate unit.

[0063] Step S20: Determine a pressure control value according to the assembly requirement data.

[0064] It should be noted that the control terminal calculates the pressure control value based on the assembly requirement data, and finally determines the force that the pressing device needs to give to the plate unit when the longitudinal rib unit and the plate unit are assembled and pressed, that is, the pressure control value.

[0065] It can be understood that in order to obtain an accurate pressure control value, further, the pressure control value is determined according to the assembly requirement data, including: determining the assembly structure form and the target assembly requirement of the plate unit and the longitudinal rib unit according to the assembly requirement data; and calculating the pressure value according to the assembly structure form and the target assembly requirement to determine the pressure control value.

[0066] In a specific implementation, the assembly structure form and the target assembly requirement of the plate unit and the longitudinal rib unit are determined according to the assembly requirement data. For example, the assembly structure form of the plate unit and the longitudinal rib unit is a longitudinal rib unit of 5m*8m, the target assembly requirement is high pressing, and the pressure control value is determined to be greater than or equal to 700KG according to the corresponding pressure requirement force of high pressing, the assembly structure form, and a preset control value calculation mode.

[0067] Step S30: Assembling and pressing the longitudinal rib unit and the plate unit according to the pressure control value to obtain an assembly and pressing image.

[0068] It should be noted that after determining the pressure control value, the control terminal needs to generate a pressing instruction according to the pressure control value, and send the pressing instruction to the pressing device, so that the pressing device performs overall assembly and pressing on the longitudinal rib unit and the plate unit based on the pressure control value in the pressing instruction. After the pressing device finishes pressing, the information that the pressing is finished is fed back to the control terminal, the control terminal issues an image acquisition instruction to the image acquisition device, so that the image acquisition device performs overall image acquisition on the pressed longitudinal rib unit and plate unit. The image acquisition device sends the acquired assembly and pressing image to the control terminal, so that the control terminal obtains the assembly and pressing image.

[0069] It can be understood that in order to accurately press the longitudinal rib unit and the plate unit, further, the longitudinal rib unit and the plate unit are assembled and pressed according to the pressure control value to obtain an assembly and pressing image, including: determining a target pressing spring according to the pressure control value; determining a target combination form according to a preset pressure range of the target pressing spring and the pressure control value; and assembling and pressing the longitudinal rib unit and the plate unit according to the target combination form and the target pressing spring to obtain the assembly and pressing image.

[0070] In a specific implementation, after determining the pressure control value, the control terminal needs to determine a compression spring with a corresponding load and in line with the use specification according to the assembly specification and the pressure control value, which is the target compression spring. Meanwhile, the number of target compression springs and the combination form among the target compression springs are determined according to the preset pressure range of the target compression spring and the pressure control value, which is the target combination form. For example, the current pressure control value is 600KG, and the preset pressure range of the target compression spring is about 100KG. Therefore, 6 target compression springs are needed to be combined for use, and the target combination form is the combination form of superimposed series connection installed in the compression device.

[0071] It should be noted that after obtaining the target combination form of the target compression spring, the control terminal generates an assembly instruction according to the target compression spring and the target combination form and sends it to the compression device. The compression device determines the target compression spring based on the assembly instruction and installs the target compression spring according to the target combination form. After installation, the longitudinal rib unit and the plate unit are assembled and compressed. After the compression device finishes compression, information about the end of compression is fed back to the control terminal. The control terminal issues an image acquisition instruction to the image acquisition device, so that the image acquisition device acquires an overall image of the compressed longitudinal rib unit and plate unit. The image acquisition device sends the acquired assembly compression image to the control terminal, so that the control terminal obtains the assembly compression image.

[0072] Step S40: determining whether the longitudinal rib unit and the plate unit are compressed according to the assembly compression image.

[0073] It should be noted that after obtaining the assembly compression image, the control terminal needs to determine whether the longitudinal rib unit and the plate unit are compressed according to the position of the longitudinal rib unit and the plate unit in the assembly compression image, and determine whether the plurality of longitudinal ribs in the longitudinal rib unit are in close contact with the plate unit.

[0074] Step S50: when the longitudinal rib unit and the plate unit are compressed, the assembly of the longitudinal rib unit and the plate unit is completed.

[0075] It should be noted that after determining that the longitudinal rib unit and the plate unit are in close contact, the control terminal generates an assembly completion instruction and sends it to the compression device and the image acquisition device. The compression device and the image acquisition device stop running according to the assembly completion instruction, thereby completing the assembly of the longitudinal rib unit and the plate unit.

[0076] It can be understood that when the control terminal determines that the longitudinal rib unit and the plate unit are not tightly fitted, the pressure compensation value needs to be calculated according to the assembly and pressing image, the secondary assembly instruction is generated based on the pressure compensation value after the pressure compensation value is determined, and the secondary assembly instruction is sent to the pressing device. The longitudinal rib unit and the plate unit are assembled and pressed again according to the pressure compensation value in the secondary assembly instruction. After the pressing device finishes the secondary pressing, the information of the pressing end is fed back to the control terminal. The image acquisition device is instructed again by the control terminal to acquire the overall image of the longitudinal rib unit and the plate unit after the pressing. The updated assembly and pressing image acquired by the image acquisition device is sent to the control terminal, so that the control terminal determines whether the longitudinal rib unit and the plate unit are tightly pressed based on the updated assembly and pressing image. If not, repeat the above steps. If it is tightly pressed, the assembly and pressing of the longitudinal rib unit and the plate unit are completed.

[0077] In the embodiment, the assembly requirement data of the longitudinal rib unit and the plate unit of the target bridge is acquired, the pressure control value is determined according to the assembly requirement data, the longitudinal rib unit and the plate unit are assembled and pressed according to the pressure control value, and the assembly and pressing image is obtained. Whether the longitudinal rib unit and the plate unit are tightly pressed is determined according to the assembly and pressing image. When the longitudinal rib unit and the plate unit are tightly pressed, the assembly of the longitudinal rib unit and the plate unit is completed. In the above manner, the pressure control value required for the assembly and pressing of the longitudinal rib unit and the plate unit can be accurately determined based on the assembly requirement data. The assembly and pressing image is obtained after the longitudinal rib unit and the plate unit are assembled and pressed according to the pressure control value. Whether the longitudinal rib unit and the plate unit are tightly pressed is determined by using the assembly and pressing image. The assembly between the two is completed after the pressing, so that the longitudinal rib unit composed of multiple longitudinal ribs and the plate unit are quickly and integrally pressed, and the assembly efficiency is improved.

[0078] Reference Figure 3 , Figure 3 The flowchart of the second embodiment of the unit assembly and pressing method based on a bridge of the application is shown.

[0079] Based on the first embodiment, the step S40 in the unit assembly and pressing method based on a bridge includes:

[0080] Step S41: edge line extraction is performed on the assembly and pressing image to obtain the edge line features of the assembly and pressing image.

[0081] It should be noted that the control terminal uses edge operators to extract the edge lines of the assembly and pressing image to obtain each edge pixel point in the assembly and pressing image. The edge line features in the assembly and pressing image are obtained by connecting each edge pixel point.

[0082] Step S42: dividing the assembly compression image according to the edge line feature and a preset unit feature to obtain a plate unit image corresponding to the plate unit and a longitudinal rib unit image corresponding to the longitudinal rib unit.

[0083] It should be noted that after obtaining the edge line feature, the assembly compression image is divided according to the edge line feature to obtain each image block in the assembly compression image, and the preset unit feature refers to the contour feature of the longitudinal rib unit, the contour feature of the plate unit, and the contour feature of a single longitudinal rib.

[0084] It can be understood that after obtaining each image block in the assembly compression image, feature matching is performed between the preset unit feature and each image block to obtain an image block corresponding to the plate unit and an image block corresponding to the longitudinal rib unit, the image block corresponding to the plate unit being the plate unit image, and the image block corresponding to the longitudinal rib unit being the longitudinal rib unit image, and each single longitudinal rib in the longitudinal rib unit image is image-labeled by a target frame.

[0085] Step S43: determining a first position coordinate set of the plate unit and a second position coordinate set of the longitudinal rib unit according to the plate unit image and the longitudinal rib unit image.

[0086] It should be noted that after obtaining the longitudinal rib unit image and the plate unit image, the coordinates of both ends of the U-shaped opening of each longitudinal rib in the longitudinal rib unit can be determined based on the longitudinal rib unit image, and the plate unit coordinates of the contact between each longitudinal rib and the plate unit can be determined based on the plate unit image, the coordinates of both ends of the U-shaped opening of each longitudinal rib being the second position coordinate set, and the plate unit coordinates of the contact between each longitudinal rib and the plate unit being the first position coordinate set.

[0087] It can be understood that in order to obtain accurate first position coordinate set and second position coordinate set, first, the determination of the first position coordinate set of the plate unit and the second position coordinate set of the longitudinal rib unit according to the plate unit image and the longitudinal rib unit image comprises: determining a first position of the longitudinal rib unit according to the longitudinal rib unit image; drawing a horizontal coordinate axis according to the first position; obtaining the first position coordinate set of the plate unit and the second position coordinate set of the longitudinal rib unit according to the horizontal coordinate axis, the plate unit image, and the longitudinal rib unit image.

[0088] In a specific implementation, after obtaining the longitudinal rib unit image, the lowest point in the longitudinal rib unit is determined according to the longitudinal rib unit image, the lowest point being the first position, a horizontal coordinate axis is established at the first position, and the first position coordinate set of the plate unit and the second position coordinate set of the longitudinal rib unit are obtained according to the established horizontal coordinate axis, each pixel point in the plate unit image, and each pixel point in the longitudinal rib unit image, as shown in Figure 4As shown, the first position coordinate set obtained according to the horizontal coordinate axis includes the coordinates at J-M, and the second position coordinate set includes the coordinates at A-H.

[0089] Step S44: determining whether the longitudinal rib unit and the plate unit are pressed according to the first position coordinate set and the second position coordinate set.

[0090] It should be noted that after obtaining the first position coordinate set and the second position coordinate set, it is further determined whether the longitudinal rib unit and the plate unit are pressed according to the first position coordinate set of the plate unit and the second position coordinate set of the longitudinal rib unit.

[0091] It can be understood that, in order to ensure that the longitudinal rib unit and the plate unit are pressed, further, the determination of whether the longitudinal rib unit and the plate unit are pressed according to the first position coordinate set and the second position coordinate set includes: obtaining a first longitudinal coordinate set in the first position coordinate set and a second longitudinal coordinate set in the second position coordinate set; when each longitudinal coordinate in the first longitudinal coordinate set is the same, determining whether each longitudinal coordinate in the second longitudinal coordinate set is the same; and when each longitudinal coordinate in the second longitudinal coordinate set is the same, determining whether the longitudinal rib unit and the plate unit are pressed.

[0092] In a specific implementation, the longitudinal coordinates of the two ends of the U-shaped opening of each longitudinal rib in the longitudinal rib unit are obtained, and the longitudinal coordinates of the two ends of the U-shaped opening of each longitudinal rib are the second longitudinal coordinate set. The longitudinal coordinates of the plate unit coordinates at the contact positions of the longitudinal ribs and the plate unit are obtained, and the longitudinal coordinates of the plate unit coordinates at the contact positions of the longitudinal ribs and the plate unit are the first longitudinal coordinate set.

[0093] It should be noted that when each longitudinal coordinate in the first longitudinal coordinate set is the same, it indicates that the plate unit is in a horizontal state at this time, and when each longitudinal coordinate in the second longitudinal coordinate set is the same, it indicates that each longitudinal rib in the longitudinal rib unit is in the same horizontal plane. When each longitudinal rib in the longitudinal rib unit is in the same horizontal plane and the plate unit is in a horizontal state, it indicates that each longitudinal rib in the longitudinal rib unit is pressed against the plate unit, and the multiple longitudinal ribs are uniformly stressed, and there is no need to perform the assembly pressing operation.

[0094] It can be understood that when the longitudinal rib unit and the plate unit are not assembled and pressed, secondary pressing needs to be performed based on the first longitudinal coordinate set in the first position coordinate set and the second longitudinal coordinate set in the second position coordinate set. Further, after the first longitudinal coordinate set in the first position coordinate set and the second longitudinal coordinate set in the second position coordinate set are obtained, the method further comprises: when each longitudinal coordinate in the first longitudinal coordinate set is different, obtaining the minimum longitudinal coordinate in the second longitudinal coordinate set; calculating the difference between each longitudinal coordinate in the second longitudinal coordinate set and the minimum longitudinal coordinate; determining the pressure compensation value corresponding to each longitudinal rib in the longitudinal rib unit according to the difference between each longitudinal coordinate and the minimum longitudinal coordinate; performing secondary assembly and pressing on the longitudinal rib unit and the plate unit according to the pressure compensation value, to obtain an updated assembly and pressing image; and determining whether the longitudinal rib unit and the plate unit are pressed according to the updated assembly and pressing image.

[0095] In a specific implementation, when each longitudinal coordinate in the first longitudinal coordinate set is different, the minimum longitudinal coordinate in the second longitudinal coordinate set is obtained, and the difference between each longitudinal coordinate in the second longitudinal coordinate set and the minimum longitudinal coordinate is calculated. According to the difference and the pressure control value, the pressure compensation value corresponding to each longitudinal rib in the longitudinal rib unit can be determined. For example, the pressure control value is 600 KG, the minimum longitudinal coordinate is 10, the longitudinal coordinate in the U-shaped opening end coordinate of the first longitudinal rib to the third longitudinal rib in the longitudinal rib unit is 10, the longitudinal coordinate in the U-shaped opening end coordinate of the fourth longitudinal rib to the fifth longitudinal rib is 12, and the difference is 2. It is indicated that the pressure compensation value corresponding to the fourth longitudinal rib and the fifth longitudinal rib is 120 KG, and the pressure compensation value corresponding to the first longitudinal rib to the third longitudinal rib is 0 KG.

[0096] It should be noted that after the control terminal obtains the pressure compensation value, the control terminal generates a secondary assembly instruction according to the pressure compensation value corresponding to each longitudinal rib to the pressing device. The pressing device starts a separate pressing mode based on the secondary assembly instruction, and presses each longitudinal rib in the longitudinal rib unit and the plate unit according to the pressure compensation value in the secondary assembly instruction in the separate pressing mode, so as to perform secondary assembly and pressing. After the pressing device ends the secondary pressing, information indicating that the pressing ends is fed back to the control terminal. The control terminal again issues an image acquisition instruction to the image acquisition device, so that the image acquisition device performs overall image acquisition on the pressed longitudinal rib unit and the plate unit. The image acquisition device sends the updated assembly and pressing image acquired to the control terminal, so that the control terminal determines whether the longitudinal rib unit and the plate unit are pressed based on the updated assembly and pressing image. If not, the above steps are repeated. If yes, the assembly and pressing between the longitudinal rib unit and the plate unit ends.

[0097] In this embodiment, edge line features of the assembly compression image are obtained by performing edge line extraction on the assembly compression image; the assembly compression image is divided according to the edge line features and preset unit features, to obtain a plate unit image corresponding to the plate unit and a longitudinal rib unit image corresponding to the longitudinal rib unit; the first position coordinate set of the plate unit and the second position coordinate set of the longitudinal rib unit are determined according to the plate unit image and the longitudinal rib unit image; and whether the longitudinal rib unit and the plate unit are compressed is determined according to the first position coordinate set and the second position coordinate set. By performing edge line extraction on the assembly compression image, the longitudinal rib unit image and the plate unit image are obtained based on the extracted edge line features and the preset unit features, and whether the longitudinal rib unit and the plate unit are compressed is determined based on the determined first position coordinate set and second position coordinate set, thereby ensuring the accuracy and efficiency of the judgment process in the assembly compression.
