Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of building construction, and in particular relates to a tower crane anti-collision system and method based on BIM. Background Art
[0002] Tower cranes are very important equipment on construction sites, used to lift and move building materials. However, due to the height and wide operating range of tower cranes, improper operation or lack of effective safety measures may lead to collisions with other buildings, structures or other tower cranes, thus causing safety accidents. In order to prevent such accidents, the following measures are usually adopted to achieve tower crane anti-collision:
[0003] The first is to install an anti-collision system: The anti-collision system of a modern tower crane uses sensors to detect the surrounding environment, including the position and movement status of other tower cranes. When a potential collision risk is detected, the system will automatically issue a warning or take measures such as slowing down or stopping.
[0004] The second approach is to use GPS positioning technology: by installing a GPS positioning device on each tower crane, the crane's position and movement trajectory can be monitored in real time, helping to avoid collisions between multiple cranes. However, the above measures are relatively simple anti-collision measures and cannot be applied to complex working conditions.
[0005] Therefore, how to provide a BIM-based tower crane anti-collision system and method is a technical problem that technical personnel in this field urgently need to solve. Summary of the Invention
[0006] Aiming at the shortcomings of the traditional tower crane anti-collision system, a tower crane anti-collision system and method based on BIM is proposed to ensure the safe construction of the tower crane.
[0007] In order to solve the above technical problems, the present invention includes the following technical solutions:
[0008] A tower crane anti-collision system based on BIM, comprising:
[0009] The BIM model is established by acquiring the spatial information of the site layout of the tower crane through oblique photography. The spatial position of any safety point on the site can be obtained by measuring the safety distance between the BIM model and buildings and on-site obstacles;
[0010] A positioning device, which is installed at the tower crane hook and is used to record the real-time spatial position of the heavy object when the tower crane is in operation;
[0011] A guide locator is installed in the tower crane cockpit, the guide locator is connected to the BIM model via a wireless transmission device, and the guide locator provides navigation for the tower crane driver.
[0012] Furthermore, the BIM model is a site layout BIM model, and the site layout space information of the site layout BIM model is picture information or data information.
[0013] Furthermore, the image information is obtained by tilting a camera to shoot the tower crane arrangement position, and the data information is obtained from the tower crane on-site arrangement design drawings.
[0014] Furthermore, the guidance locator includes an electrically connected data processing chip, a data receiving and transmitting antenna, a direction control key, a display screen and a power key.
[0015] Furthermore, the positioning device includes a body, a rubber ring is provided on the outside of the body, a positioning chip, a positioning data transmission device and a battery are provided on the body, and the positioning data transmission device is powered by the battery.
[0016] Furthermore, it also includes a camera, which is arranged at the tower crane hook.
[0017] The present invention also provides a tower crane anti-collision method based on BIM, which includes the following steps:
[0018] Step S1: providing the BIM-based tower crane anti-collision system for standby use;
[0019] Step S2: Obtaining the spatial information data of the tower crane site layout through oblique photography, and establishing a site layout BIM model;
[0020] Step S3: Mark the safety range of buildings and on-site obstacles on the site layout BIM model, and obtain the spatial position of any safety point on the site through the site layout BIM model and its safety distance range;
[0021] Step S4: Securely locate the tower crane hook, obtain the real-time spatial position of the tower crane through the positioning device, and calculate the spatial position of any point of the heavy object hoisted by the hook;
[0022] Step S5: Install a guide locator in the tower crane cockpit, and import the site layout BIM model into the guide locator via a wireless device. The guide locator can display the position information of the heavy object in real time when the tower crane is running. The tower crane driver makes driving adjustments based on the navigation prompts of the guide locator.
[0023] Furthermore, step S5 includes: checking the surrounding conditions during the operation of the tower crane through the site layout BIM model, reading the positioning chip on the tower crane positioning device, obtaining the position information of the tower crane during operation, and transmitting the position information of the tower crane during operation to the guide locator through a wireless transmission device, and displaying it through the display screen of the guide locator.
[0024] Furthermore, a camera is associated with the guide locator, and the images and videos captured by the camera are sent to the guide locator via a wireless transmission device. When a person appears within the camera's field of view, the person is promptly advised to leave via a warning device.
[0025] Furthermore, the camera captures geometric information of the irregular heavy object, and calculates the spatial position of any point of the irregular heavy object through the geometric information and the positioning device.
[0026] Compared with the prior art, the present invention has the following advantages and beneficial effects:
[0027] The present invention provides a BIM-based tower crane anti-collision system, comprising a BIM model, a positioning device and a guide locator. The BIM model is established through the spatial information of the site layout of the tower crane. The spatial position of any safety point on the site can be obtained through the safety distance between the BIM model and buildings and on-site obstacles. The positioning device is installed at the tower crane hook and is used to record the real-time spatial position of the heavy object when the tower crane is in operation. The guide locator is installed in the tower crane cockpit and is connected to the BIM model through a wireless transmission device. The guide locator provides navigation for the tower crane driver.
[0028] The BIM-based tower crane anti-collision system is an important guarantee for construction safety, mainly reflected in the following aspects:
[0029] First, real-time monitoring and early warning: The system monitors the crane's operating status in real time, including location, speed, direction, and other information, and displays this information visually through the BIM model. Once a potential collision risk is detected, the system immediately issues an early warning, prompting the operator to take appropriate measures, effectively avoiding the collision.
[0030] Second, precise simulation and optimization: Using BIM technology for tower crane collision avoidance simulation allows for precise simulation of the crane's trajectory and slewing radius before construction begins. This allows for the crane's impact zone and the potential reach of its swing arm within a specific construction section. This helps managers develop reasonable tower crane safety management plans and reduce safety risks by optimizing construction plans.
[0031] Third, it improves safety and efficiency: Through real-time monitoring, precise simulation, and data integration, the BIM-based tower crane collision avoidance system can significantly improve the safety and efficiency of construction. The system not only effectively prevents tower crane collisions but also optimizes the crane's trajectory, improving construction efficiency and reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS
