[0002] BIM technology is a digital tool used in engineering design, construction, and management. By integrating the digital and information models of buildings, it is shared and transmitted throughout the entire life cycle of project planning, operation, and maintenance, enabling engineering and technical personnel to correctly understand and efficiently respond to various building information.

[0003] During construction, a complete engineering project is usually divided into several sub-projects. In order to improve efficiency, most staff will use raw materials to produce finished materials that meet the construction requirements in advance according to the sub-projects to be constructed. However, in the process of producing finished materials, some construction materials may not meet the construction requirements due to construction errors. In order to solve this problem, most of the current methods use manual measurement to test the finished materials one by one. However, manual measurement often has deviations, which may lead to the discovery that the finished materials cannot meet the construction requirements during the construction process, which will affect the construction progress to a certain extent. Summary of the invention

In the simulated construction process, when the finished material data of the magic clothing does not meet the construction requirements, it can be intuitively discovered according to the established second BIM model.

DETAILED DESCRIPTION

It should also be understood that terms defined in general dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0061] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0062] The present application embodiment discloses a BIM-based engineering supervision method. Figure 1 , BIM-based engineering supervision methods include:

[0063] S101: Acquire the sub-projects to be constructed, the finished material data and the first BIM model of the completed construction stage.

[0064] Specifically, during construction, a complete engineering project is usually divided into several sub-projects. The sub-projects to be constructed are sub-projects that are about to be constructed. Before construction, the sub-projects to be constructed are manually input through external devices, and the input sub-projects to be constructed are stored in a database. When the sub-projects to be constructed need to be obtained, the server retrieves the corresponding sub-projects to be constructed from the database. In this embodiment, the external device can be a mobile phone, a computer, or other device that can input information.

[0065] During construction, the material data of each sub-project will be stored in the database. Before the construction of the sub-project to be constructed, the server retrieves the material data of each completed sub-project from the database, and establishes a first BIM model based on the material data of each completed sub-project, and stores the first BIM model in the database. The server retrieves the first BIM model from the database when needed. The establishment of the BIM model is a well-known technical means for those skilled in the art, and will not be described in detail here.

[0066] Before carrying out the sub-item to be constructed, in order to ensure construction efficiency, the finished materials required for the sub-item to be constructed are first manufactured according to the construction requirements, and a placement area is designated at the construction site to hold the finished materials. The placement area is determined according to the type, shape and size of the finished materials. After the placement area is designated, the characteristic information of the placement area is uploaded to the server and stored in the database. The characteristic information includes the size and shape of the placement area.

[0067] A plurality of image acquisition devices are arranged at the construction site to acquire image information of finished materials and placement areas. The image acquisition devices upload the acquired image information to the server. The server identifies the received image information, determines the ratio of each finished material to the placement area, and then calculates each finished material data according to the determined ratio of each finished material to the placement area and the characteristic information of the placement area. The finished material data is the size of the finished material, and the determined finished material data is stored in a database. When necessary, the server retrieves the corresponding finished material data from the database according to actual needs.

[0068] For example: when constructing a building, a large number of floor slabs are needed. Most of the floor slabs are in the shape of a cuboid. In order to facilitate the determination of the size of the floor slabs through image recognition, a rectangular trough-shaped placement area is designed at the construction site. After the finished materials are processed, each finished material is placed in the placement area. The length, width and height of the placement area are A, B and C respectively. The ratio of the length of the floor slab to the length of the placement area is 1:3, the ratio of the width of the floor slab to the width of the placement area is 1:5, and the ratio of the height of the floor slab to the height of the placement area is 3:1. Therefore, it can be determined that the length, width and height of the floor slab are A / 3, B / 5 and 3C respectively.

[0069] S102: Building a second BIM model based on the sub-project to be constructed, the finished material data and the first BIM model to simulate the construction process.

[0070] S103: Determine whether there is a problem based on the second BIM model.

[0071] In step S102 and step S103, specifically, according to the acquired data of the sub-project to be constructed and the finished material, a second BIM model is established on the basis of the first BIM model to simulate the construction process of the sub-project to be constructed. During the construction simulation, when the data of a certain finished material does not meet the construction requirements, the first BIM model cannot be built. At this time, a prompt message is output, and the staff can intuitively find the problematic construction nodes according to the second BIM model.

[0072] S104: If yes, determine the cause of the problem according to the second BIM model.

[0073] Specifically, when it is determined that the server outputs a prompt message, the server simultaneously obtains the construction data of the construction node that causes the prompt message to be generated. The construction data includes the finished material data corresponding to the construction node and other construction data associated with the finished material data. The cause of the problem is determined based on the correlation between the data.

[0074] For example, when a floor slab cannot be placed at the construction location during floor construction, the size of the floor slab is first determined, and then the distance between the supporting materials used to support the floor slab is obtained. For example, if the distance between the supporting materials is E, and the length of the floor slab is F, F=E+e under normal conditions; e is a fixed constant; therefore, when F<E+e, the cause of the problem is determined to be that the floor slab is too short, and when F>E+e, the cause of the problem is determined to be that the floor slab is too long.

[0075] S105: Determine the solution to the problem based on the cause and case library.

[0076] Specifically, a case library is established through the big data of building plans. The case library stores cases in which problems arise in the construction process due to various reasons, as well as corresponding solutions and the time and cost of adopting the solutions. After the cause of the problem is determined, cases that lead to such problems due to the cause and corresponding solutions are retrieved from the case library based on the cause of the problem. The solutions include material adjustment and construction method adjustment.

[0077] S106: Determine a target solution based on a preset determination rule.

[0078] Specifically, the construction personnel determine the constraints according to the current construction process. The constraints are factors that will affect the solution of the problem. For example, in this embodiment, the constraints include cost and construction period. After the constraints are determined, the construction personnel determine the importance of different constraints according to the actual situation and set a weight for each constraint. The higher the weight, the more important the corresponding constraint. For example, in the current state, the construction period should be shortened as much as possible, so the weight corresponding to the construction period is set to 70%, and the weight corresponding to the cost is set to 30%. The constraints are sorted from high to low according to the weights, and the sorting result is construction period and cost; after the sorting is completed, the solutions are sorted from short to long according to the construction period corresponding to each solution, and the solution with the shortest construction period is determined. After the solution with the shortest construction period is determined, the number of solutions is determined. If the number of solutions is equal to 1, the solution with the shortest construction period is determined according to the cost. After the sorting is completed, the solution with the lowest cost among the solutions with the shortest construction period is determined. If the number of solutions with the lowest cost among the solutions with the shortest construction period is equal to 1, then the solution is the target solution. If the number of solutions with the lowest cost among the solutions with the shortest construction period is greater than 1, then any solution with the lowest cost among the solutions with the shortest construction period is selected as the target solution. In this embodiment, the number of constraints and the weight corresponding to each constraint can be set according to the actual working conditions, and there is no restriction here.
