Description

Technical Field

[0001] The present invention relates to the technical field of process identification equipment, and in particular to a precast beam process identification system and method. Background Art

[0002] The statements in this part only provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Today, with the rapid development of engineering economy, highway bridges have flourished. During the development of bridge forms, multiple branches have emerged. Among them, precast beams are widely used in the construction of highway bridges due to their advantages such as low cost, high quality, short construction period, and beautiful appearance. As an important part of the bridge construction process, the construction progress management of precast beams directly determines whether the bridge construction task can be completed on schedule. If the beam erection construction is called the "front field" and the precast beam production progress is called the "back field", the coordinated control of the construction progress of the front and back fields is surely an effective means to ensure the orderly progress of the precast beam bridge construction.

[0004] Currently, the identification of precast beam processes in the construction progress management system mainly relies on manual labor. Construction workers scan the QR codes on the beam bodies on site, and manually identify and input the process progress into the progress management system one by one, which often results in excessive manual input, serious material loss, and low management efficiency, leading to high production costs and low efficiency in the beam yard. Currently, there is also a video automatic identification system for automatic collection of process information. However, the inventor found that the existing system requires the camera to be directly facing the precast beam construction pedestal. When the number of precast beam construction pedestals is large, a large number of cameras need to be installed to collect process information, and the cost is difficult to control. Summary of the Invention

[0046] As introduced in the background art, there is a problem in the prior art that the progress of the precast beam process mainly depends on manual inspection. To solve the above technical problems, the present invention proposes a precast beam process identification system.

[0047] Embodiment 1

[0048] In a typical embodiment of the present invention, referring to Figure 1 as shown, a precast beam process identification system includes:

[0049] A gantry crane 102, both sides of the gantry crane 102 are supported by traveling rails 105, and the gantry crane 102 can move along the traveling rails 105;

[0050] A process identification mechanism 101, the process identification mechanism 101 is installed on the main beam of the gantry crane. A first rail is provided below the main beam, and the first rail is located below or on the side of the main beam of the gantry crane. The first rail is arranged along the length direction of the main beam. The process identification mechanism includes a collection unit 304, a communication unit 305, and a control unit 303 that are connected in sequence. The control unit 303 is also connected to a mobile control unit 301, and the mobile control unit 301 is used to control the process identification mechanism to move along the first rail;

[0051] The mobile control unit 301 is connected to a driving component. Referring to Figure 4 as shown, the driving component 403 specifically includes a driving power source such as a driving motor. The driving motor is connected to a driven wheel 401, the driven wheel 401 is connected to a driving wheel 302, the driving wheel 302 is supported by the first rail, and the driving component 403 drives the driving wheel 302 to move along the first rail through the driven wheel 401;

[0052] The collection unit 304 is fixed to the control unit 303, and the collection unit is used to obtain the state of the precast beam 103;

[0053] A communication unit 305, which is used to transmit the data information collected by the collection unit to the control unit;

[0054] The control unit 303 is used to process and classify the data transmitted by the collection unit. The control unit matches the classification result with the process classification model built in the control unit, so as to identify the process of the precast beam 103 corresponding to the image information transmitted by the collection unit.

[0055] Reference Figure 3 As shown, the control unit is arranged inside the housing, and the acquisition unit is fixed below the housing; in this embodiment, the traveling guide rail and the first guide rail are specifically existing guide rails for track robots.

[0056] Among them, it can be understood that the control unit 303 is also used to store and statistically analyze the data information collected by the acquisition unit, and the control unit 303 is connected to the alarm unit; the control unit receives the information from the acquisition unit and the movement control unit, and when the information sent by the acquisition unit and the movement control unit fails, the control unit controls the alarm unit to give an alarm. The alarm unit is specifically an alarm lamp or a buzzer; the alarm unit can be fixed on the side of the housing for the convenience of the staff to observe the alarm information.

[0057] In addition, the housing plays a role in protecting the control unit, and the housing also plays a role in supporting the movement control unit and the acquisition unit, so that the driving component drives the acquisition unit to move along the first guide rail through the housing. The driving component 403 is fixed on one side of the housing of the control unit, and a braking component 402 is arranged on the driving wheel 302. The braking component is an existing braking component for track walking wheels. The braking component 402 is connected to the driving wheel 302, and the control unit controls the braking component 402 to act, and the braking component controls the driving wheel 302 to stop rotating.

[0058] It can be understood that the precast beam 103 is constructed on the pedestal 104. The pedestals are arranged in multiple rows and columns. There is a precast beam being manufactured on each pedestal. The adjacent two precast beams in each row are arranged at an interval of a first distance, and the adjacent two precast beams in each column are arranged at an interval of a second distance. Through the settings of the first distance and the second distance, it is convenient for the staff to move forward. Two traveling guide rails 105 are arranged on both sides of the precast beams 103 in multiple rows and columns.

[0059] In this embodiment, reference Figure 2 As shown, the traveling guide rail 105 is laid with a first grating array sensing optical fiber 201, and the first grating array sensing optical fiber is connected to the control unit to obtain the position information of the gantry crane 102;

[0060] The first guide rail is laid with a second grating array sensing optical fiber 404, and the second grating array sensing optical fiber is connected to the control unit to obtain the position information of the acquisition unit. Through the settings of the first grating array sensing optical fiber 201 and the second grating array sensing optical fiber 404, it is convenient for the control unit to obtain the position information of the precast beam 103 corresponding to the image information captured by the acquisition unit; the control unit can determine the position information of the pedestal where the precast beam is located according to the position information sent by the first grating array sensing optical fiber 201 and the second grating array sensing optical fiber 404, so as to match the pedestal number information stored in the control unit.

[0061] In this embodiment, the acquisition unit includes a connecting rod connected to the housing. The top end of the connecting rod is located below the housing. Refer to Figure 5 as shown. The connecting rod is connected to the rotating member 505, and the rotating member 505 is connected to the camera 504. A light source is arranged on the periphery of the camera. The camera, the light source, and the rotating member are separately connected to the control unit. The control unit also obtains the angle information of the camera, so that after the process identification mechanism reaches the pedestal position, the control unit controls the rotating member to rotate. While the rotating member is rotating, the acquisition unit takes pictures until the best image information corresponding to the pedestal is obtained (this process is a calibration process, and it can also be manually intervened, and the staff determines the best image information corresponding to each pedestal). The control unit will record the angle of the camera and the extended length of the telescopic rod corresponding to the best image information of the corresponding pedestal, and directly rotate the rotating member to the appropriate position and extend the telescopic rod to the set length to take the best image information of this position next time.

[0062] Specifically, the rotating member 505 includes a first rotating motor. The fixed end of the first rotating motor is connected to the bottom end of the connecting rod. The first rotating motor can control the camera to rotate 360 degrees in the horizontal direction. The first rotating motor is connected to the second rotating motor, and the second rotating motor is connected to the camera 504. The second rotating motor controls the camera to rotate 180 degrees vertically and records the angle of the lens.

[0063] It can be understood that the light source includes a normal light source. The normal light source can be an LED lamp 503 for supplementary lighting. The light source also includes an infrared light source 502. The infrared light source 502 can be arranged at one place. One or more LED lamps can be arranged on the periphery of the camera 504. High-definition images are collected by the high-definition camera under good daylight conditions. The infrared light source is turned on when the light is insufficient at night to collect infrared images. The LED lamp 503 can be called for supplementary lighting in some environments.

[0064] In this embodiment, the connecting rod is a telescopic rod, specifically an electric telescopic rod. The electric telescopic rod is connected to the control unit, which further ensures that the images taken by the acquisition unit are clearer, so that the telescopic rod can adjust the height of the process identification mechanism within the range of 0 to 60 cm.

[0065] It is understandable that the control unit is specifically an industrial control computer embedded in the device, with the Windows 11 operating system built-in, device drivers and process recognition algorithm programs built-in. The process recognition algorithm program is provided with a process classification model, specifically using the existing object detection and classification model YOLOv7 model. The control unit can realize the recognition of pedestal occupancy and process status through existing image recognition and deep learning technologies; the communication unit supports WiFi and 4G wireless transmission protocols, and can realize remote control of the device and wireless transmission of recognition results. The control unit controls the actions of each component in the acquisition unit. The controller is connected to a remote terminal, which is specifically a remote computer. The remote computer can obtain relevant image information and is placed in the project management system, facilitating the integration of pedestal numbers, precast beam processes, and precast beam codes, and convenient for staff to view.

[0066] It should be explained that when the gantry crane moves along the traveling guide rail, it generates a vibration response. When the process recognition mechanism moves along the first guide rail, it generates a vibration response. The demodulator is connected to the control unit. The demodulator analyzes the vibration response data collected by the first grating array sensing optical fiber and the second grating array sensing optical fiber, and realizes the positioning of the process recognition mechanism according to the vibration intensity.

[0067] In addition, two-dimensional code information is set on the surface of the precast beam (the two-dimensional code information covers information such as the production number (WBS code and EBS code), model, length, width, height, etc. of the precast beam). During the production process of the precast beam, the two-dimensional code is printed on the surface of the support plate, and the support plate is fixed on the surface of the steel mesh and / or formwork. The control unit picks up the two-dimensional code information on the surface of the precast beam according to the image information transmitted by the acquisition unit, and obtains the encoded information of the precast beam after processing, further ensuring that the precast beam information obtained by the control unit is relatively comprehensive;

[0068] In the identification system provided by this embodiment, during the construction process of the precast beam, the gantry crane continuously adjusts its position according to the construction requirements. To complete the identification task of all pedestal precast beam processes in the target area, the process recognition mechanism needs to move on the main beam of the gantry crane to solve the problem of target occlusion, and adjust the angle of the camera through the rotating component to realize the image acquisition of all pedestal precast beam processes. The control unit corresponds the collected precast beam position information with the pedestal numbers stored in the control unit, then corresponds it with the encoded information of the precast beam, and finally corresponds it with the image information collected by the acquisition unit, and transmits it to the project management system of the remote terminal, which is convenient for the staff to view. The whole process realizes the rapid, accurate identification and automatic filling of the precast beam process, and solves the problems of long working hours and low efficiency due to the dependence of the precast beam process progress on manual inspection, statistics, and filling.

[0069] Embodiment 2

[0070] Reference Figure 6As shown in the figure, this embodiment provides a working method for a precast beam process identification system, including the following content:

[0071] Step 1: The process identification mechanism is connected to a computer through a network cable to configure an IP address (Internet Protocol address), set wireless network parameters. After completion, the process identification mechanism is installed on the first guide rail of the gantry crane main beam, and grating array sensing optical fibers are respectively laid on the gantry crane travel guide rail and one side of the first guide rail. One end of the grating array sensing optical fiber is connected to a signal demodulator. After the installation is completed, the process identification mechanism is powered on and connected to the wireless network.

[0072] Step 2: Use a computer under the same local area network to search for the controller IP address of the process identification mechanism, and enter the controller through remote connection for parameter debugging. Move the gantry crane to different positions, control the process identification mechanism to move on the first guide rail of the gantry crane and rotate the camera angle to ensure that a complete, clear, and unobstructed image of the target area can be obtained. Record the best system position and lens angle at different gantry crane positions. Enter the WBS code and EBS code information of the precast beam, and enter the corresponding situation between the pedestal and the precast beam (only when the corresponding relationship between the WBS code and the EBS code is known can the recognition result be synchronized to the existing Building Information Modeling (BIM) model for display). Set parameters such as the recognition interval, working duration, and data transmission address.

[0073] The purpose of the process identification mechanism is to identify which precast beam is being constructed on which pedestal, which precast beam it is (the structural code is the WBS code), and the construction progress of the precast beam, and then display the actual construction progress correspondingly on the BIM model of the remote terminal. The component code of the BIM model is the EBS code;

[0074] Step 3: Start working, start the process identification mechanism. The process identification mechanism identifies the precast beam process based on the image information captured by the camera, matches the WBS code and EBS code information of the precast beam according to the precast beam two-dimensional code information, and transmits the recognition result to the remote terminal.

[0075] Step 4: During the construction process in the beam yard, if the position of the gantry crane changes, the device automatically searches for the optimal shooting position, rotates the lens to the best shooting angle, automatically identifies the process and enters it into the project management system of the remote terminal.

[0076] Among them, it can be understood that the control unit can determine the position information of the pedestal where the precast beam is located according to the position information sent by the first grating array sensing optical fiber and the second grating array sensing optical fiber, so as to match the pedestal number information stored in the control unit. In this way, the control unit corresponds the process information of the precast beam with the pedestal information, which is convenient for management.

[0077] In addition, since the precast beams also have different codes, two-dimensional code information is set on the surface of the precast beams. The acquisition unit sends the transmitted image information to the control unit, and the control unit picks up the two-dimensional code information on the surface of the precast beams and performs super-resolution processing to obtain the precast beam code information. Thus, the control unit matches the precast beam code information with the identified process information of the precast beam, which further facilitates management.

[0078] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
