Description

[Technical Field]

[0001] The present invention relates to the field of digital twins, and more particularly to a construction equipment placement system based on digital twins. [Background technology]

[0002] Dynamic layout of construction equipment is an important part of the construction process, and rational layout of construction equipment is an important guarantee for the smooth progress of the entire construction and shortening of the construction period. Therefore, it is necessary to rationally plan the dynamic management of all construction equipment both before and during construction. However, traditional construction equipment layout relies on experience and artificial design, and is easily affected by subjective factors and restrictive conditions, which makes the layout plan limited and inefficient.

[0003] Digital twins are a simulation technology that links a digital image of the real world with its digital model, enabling interaction, feedback, and optimization. During project construction, digital twin technology can accurately provide a three-dimensional construction site environment and display the interrelationships between different elements such as buildings, machinery, and work areas, greatly facilitating machinery layout planning and optimization during construction. However, in a real construction environment, multiple machinery and equipment participate in the layout simultaneously, and the layout environment is subject to dynamic uncertainty, which can easily lead to conflicts in the equipment layout plan. Furthermore, there is a lack of judgment regarding obstacles in the planning and layout process, resulting in a certain lack of precision in the equipment layout.

[0014] The following examples of the present invention are described in detail. The following examples are implemented based on the technical solutions of the present invention, and provide detailed embodiments and specific operation procedures, but the scope of protection of the present invention is not limited to the following examples.

[0015] The present invention designs a construction equipment placement system based on digital twin. As shown in Figure 1, the technical solution is as follows: Including a data collection module, a data transmission module and a digital twin management module, The data collection module is used to place sensors at the construction site and collect device placement information in real time. The data transmission module is used to transmit the configuration information to the digital twin management module in real time; The digital twin management module is used to combine the layout information to build a digital twin model of the construction site and to plan the equipment layout. As shown in FIG. 2, the equipment layout plan includes: Step S10: arranging all the devices at the construction site based on a preset arrangement plan; Step S20: determining whether the obstacle road situation and the preset arrangement plan of the current device are correlated, and if so, executing S30; otherwise, executing S40; Step S30: updating the digital twin model and adjusting the preset deployment plan of the current device; and step S40 of continuing the placement until all the devices at the construction site have been placed.

[0016] Preferably, the device location information includes device location information and time information.

[0017] Preferably, the data transmission module includes a 5G network and / or an optical fiber network.

[0018] Preferably, S10 comprises: A step of constructing a three-dimensional construction site scenario using the digital twin model, pre-setting a plurality of nodes in the three-dimensional construction site scenario as a pre-set arrangement plan, and sequentially moving all devices through the respective pre-set nodes to complete the arrangement; and setting a corresponding time window for the predetermined node to represent the time at which the corresponding device arrives at the node and the three-dimensional position of the node.

[0019] Preferably, the time window formula is as follows:

number

[0020] Preferably, step S20 comprises: The method includes inputting obstacle road condition information into a digital twin model and identifying it in node form in a three-dimensional construction site scene, outputting obstacle nodes and corresponding time windows, and determining that the obstacle road condition is correlated with the preset layout plan of the current device if the preset node time window and the obstacle node time window overlap, and executing S30; otherwise, executing S40.

[0021] Specifically, the preset deployment plan involves the current device moving along the preset nodes and completing the deployment process when it arrives at the deployment point. To represent the deployment status of the current device, the node time window in the preset plan for the current device is obtained through the mapping relationship of the digital twin model. The obstacle road condition node represents the location of obstacle road conditions that may occur during construction. Each obstacle road condition node has a time window to represent the time range and three-dimensional location of the obstacle. The newly constructed path node is reconstructed using the current device's location as the new starting point when updating the digital twin model. These new nodes also have time windows to represent the time range in which the device will arrive at these nodes. The overlapping nodes to be removed are nodes whose time windows overlap with the obstacle road condition time window. These nodes may affect the movement of the device and therefore need to be processed during deployment. The inter-device node collision node is a node that determines whether there is a node collision between devices. The time windows between devices are compared to determine whether the nodes overlap. If there is an overlap, processing is required, such as waiting for a while before the device enters the overlapping node. These time windows cover node-related information such as pre-set deployment plans, obstacle road conditions, newly constructed route nodes, overlapping nodes to be removed, and node collisions between devices, and are used to guide the movement and adjustment of devices during the deployment of construction equipment, thereby improving the accuracy and efficiency of construction equipment deployment.

[0022] Step S10 further includes performing node optimization for a preset plan, and the starting node p n1 From the end point p nM The five adjacent nodes are set as the local device placement route, and the preset placement plan is divided into multiple local device placement routes.

[0023] Preferably, as shown in FIG. 3, step S30 includes: The current device position is set as the start node p1, and the end node p M remains unchanged and multiple new path nodes p m Step S3001 of reconstructing the a step S3002 of removing new path nodes whose time windows overlap with obstacle node time windows; It is determined whether the new route node time window overlaps with the node time windows of all other devices. If it overlaps, it is determined that there is a node collision. The device waits a time Δt m Step S3003, which requires waiting; Step S3004 of setting an objective function for fastest placement time based on nodes and latency; and step S3005 of solving the objective function, determining the positional relationship of each node, and adjusting the placement plan of the current device.

[0024] Preferably, the objective function formula is:

number

[0025] Specifically, conventional placement path adjustments only change and optimize nodes, but often ignore obstacle time. For example, if an obstacle is present for a short time, the system can wait at the obstacle node before entering the obstacle node, thereby reducing the time required to relocate the node. A waiting time is set for each node, and a value is assigned to the waiting time based on whether or not there is a node collision. If it is determined that there is no node collision, the waiting time is set to 0. If it is determined that there is a node collision, the size of the waiting time is determined based on the obstacle time window. This minimizes the placement time of devices and improves placement efficiency based on node and time constraints.

[0026] The above is a detailed description of the preferred specific embodiments of the present invention. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without any creative work. Therefore, any technical solutions that those skilled in the art can obtain based on the concept of the present invention through logical analysis, reasoning, or limited testing based on the prior art should fall within the scope of protection determined by the claims.
