BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a schematic diagram of the main process of the method of this application.

[0016] Figure 2 It is a schematic diagram of the structure of the system of this application. DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-2 This application is described in further detail.

[0018] An embodiment of the present application discloses a material tracking method based on a BIM parametric model.

[0019] Reference Figure 1 , material tracking methods based on BIM parametric models include: S1. Establish a digital material library; S2, warehouse in and out management; and S3. Update the model.

[0020] This method determines the information of engineering materials through the BIM model to establish a matching digital storage space, and automatically identifies the materials entering and leaving the material yard and storage warehouse, updates the digital storage space and construction progress, and realizes automatic tracking of construction materials, thereby improving the management effect of the BIM system on engineering materials.

[0021] The above-mentioned digital material library is established, which includes: 1-1) Obtain the bill of materials required for construction based on the pre-established BIM model.

[0022] It can be understood that this method is implemented with the help of the BIM system / platform, so the model of the corresponding engineering project is directly called from the system / platform, and the components of each structure are obtained based on the model analysis, and the required materials are further analyzed and calculated, for example: the length and type of pipelines; then, the materials list is summarized and classified.

[0023] It should be noted that the bill of materials should be sent to relevant staff for confirmation, and the next step can only be carried out after confirmation.

[0024] 1-2) Create a database of corresponding materials, and establish multiple subspaces corresponding to various materials based on the bill of materials.

[0025] It should be noted that this method does not involve adding a new material and then creating a set of data (positions) in the database table. Instead, the corresponding subspace is created based on the list first, and other information is matched in the next step. This can be considered as: "Prepare the shelves one by one and empty the positions on the shelves one by one."

[0026] The advantage of the above settings is that the staff can directly check how many "vacancies" there are and the "shelf vacancy rate" to quickly infer the material order, production progress, and even the project progress.

[0027] 1-3), the first case: if a certain material meets the preset piece-counting conditions, multiple identification sequences are allocated to the matching subspace according to the corresponding quantity of the material.

[0028] Example of piece-counting conditions: prefabricated floor slabs, prefabricated pipes and other large and counted components. The rule for using the identification sequence is that the materials entering the designated material yard and storage warehouse match the identification sequence respectively. In this embodiment, the identification sequence number includes letters and numbers. The letters can be the abbreviation of the material name, and the numbers can be natural numbers. The end number is the quantity of the material.

[0029] Therefore, as the construction progresses, the materials in the advanced library only need to be assigned small identification sequences, and then the current progress of the project can be inferred from the numbers of the identification sequences in the library.

[0030] The second case: If a certain material meets the preset unit measurement conditions, the corresponding unit data is allocated according to the subspace corresponding to the material.

[0031] Example of unit measurement conditions: a large number of scattered components such as bricks; example of unit data: XX cubic meters; example of UI display effect: The red number shows the total number of cubic meters, n; if 100 cubic meters are imported, the green number below shows n-100 cubic meters; after that, 50 cubic meters are used, and the yellow number below shows +50. With this setting, you only need to look at the green data to know how much material has been imported, look at the yellow data to know how much has been used, and look at the red and yellow data to infer the construction progress.

[0032] The above-mentioned inbound and outbound management includes: 2-1) Obtain the input and output data obtained by the data collection module preset in the material yard and storage warehouse.

[0033] It is understandable that the material tracking method requires the cooperation of electronic devices. In this embodiment, the data acquisition module includes: Multiple cameras are installed in material yards and storage warehouses by means of poles or suspensions to capture on-site images.

[0034] 2-2) Identify the input and output data to obtain material information and input and output behavior information; 2-3) Update the database based on material information and entry and exit behavior information.

[0035] The above update model includes: 3-1) Predict the destination of the materials according to the information of the materials used and the construction progress of the current project. Example: The materials used are prefabricated floor slabs, and the construction progress shows that the second floor slabs have been laid. The predicted destination of the materials is: used for laying the third floor slabs.

[0036] 3-2) According to the predicted material destination, find the preset construction time calculation rules and calculate the theoretical time.

[0037] Regarding the calculation rules for construction time, for example: staff record the average time for each project based on past experience, and record whether it is affected by the weather; if so, such as: the standard time for pouring the floor slab is 5 days, and then it rains one day, then one day is added and it is considered to be 6 days.

[0038] 3-3) Update the construction progress of the BIM model based on the predicted material destination and theoretical time consumption, and send it to the designated user (such as the project manager).

[0039] For example: If the material is destined for the stairs on the second floor and the theoretical time required is 2 days, then the stairs on the second floor in the building model will be colored green on the third day after the material is taken.

[0040] According to the above content, this method can automatically track construction materials on the one hand, and on the other hand, it can also cooperate with the BIM model to help staff clearly understand the progress of the project, so as to guide them to plan their work in advance, avoid problems such as insufficient or excessive materials, and improve the management effect of the BIM system on project materials.

[0041] In another embodiment of the method, the above-mentioned inbound and outbound management: If the data collection module uploads the scene picture, the scene picture is identified to determine the type of material taken. That is, the monitoring video captured by the camera is used to identify the behavior of the staff. If there is a picture of transferring the goods stacked in places, shelves, etc. to carts or transport vehicles, it is considered that the materials are being taken, and the type of the materials taken is determined at this time. It can be understood that human behavior recognition and object recognition are existing technologies, so they will not be repeated.

[0042] After that, in the first case: if the taken material meets the preset piece counting conditions, the image and induction tracking process is initiated.

[0043] Before executing the above process, this method: The weight of objects entering the material yard and storage warehouse is obtained (through a pre-installed weighing module, such as a floor scale) and tracked based on the on-site image; that is, when a transport truck enters the material yard, multiple cameras work together to track the transport truck.

[0044] If material storage behavior (taking materials from the transport vehicle and stacking them on the ground, etc.) is identified in the tracked on-site footage, the stored materials are identified, and the weight of the corresponding vehicle / container when it leaves the material yard and storage warehouse is obtained, and the unloading weight is calculated (combined with the weight when it enters).

[0045] The material quantity is calculated based on the pre-recorded piece weight and unloading weight of each material and an identification sequence is assigned accordingly.

[0046] According to the above settings, this application can realize automatic storage of materials.

[0047] Based on the above, the image and sensor tracking process includes: Conduct (time) tracing based on the carrier / container corresponding to the material taking behavior, and obtain its weight when it enters the material yard or storage warehouse; Obtain the weight of the carrier / container corresponding to the material to be picked up when it enters the material yard or storage warehouse, and calculate the pickup weight (combined with the weight at the time of entry); Identify the materials being picked up and calculate the quantity picked up based on the pre-recorded piece weights of each material; Clear the same number of identification sequences in the corresponding subspace according to the pickup quantity (note that the same sequence will not appear again in this project to avoid confusion).

[0048] According to the above settings, for piece-rate materials, this application can complete automatic tracking of entry and exit through weighing sensing and image coordination, and the staff can also quickly determine the construction material situation through the number of remaining identification sequences; if the identification sequence is still bound to a date when it is enabled and activated, this method can also allow staff to track the usage of each batch of materials.

[0049] In order to prevent errors in piece-counting and material analysis when there are multiple people on the transport vehicle when it enters and only one person on the vehicle when it leaves, the image and induction tracking process also includes: Identify the number of people loaded when the carrier / container corresponding to the material taking behavior enters and exits; If the number of people entering is greater than the number of people leaving, facial recognition will be performed on the people entering and leaving respectively, and the identities of those who have not left will be determined and tracked until they leave. The weight when they leave will be obtained, and the weight of the goods picked up will be updated according to the weight obtained when the people who have not left leave leave, and then the quantity of goods picked up will be calculated; If the number of people entering is less than the number of people leaving, facial recognition will be performed on the people entering and leaving to determine the identity of the people joining, and their movement trajectory will be traced to determine the weight of the people joining. The pickup weight will be updated based on the weight of the people joining, and then the pickup quantity will be calculated.

[0050] The above-mentioned movement trajectory is traced back to determine the weight of the person who joins. For example: A is the person who joins. The time when he enters the material yard is determined according to the monitoring records, and the picture at this time is identified. If he walks in, the weight measured at the corresponding time is obtained; if he enters by a vehicle, the weight of the vehicle is obtained, and then the weight of the vehicle when it leaves is obtained, and the weight of A is obtained by comparison.

[0051] The above is the in-and-out management when the material meets the piece-rate conditions. The following describes the second situation: if the material taken meets the preset unit measurement conditions, then: Extract the features of the vehicle / container in the scene and identify the type of the vehicle / container; for example, identify carts and transport vehicles; According to the type of carrier / container, a preset carrier / container specification database (the database records, for example, specification parameters of various carts) is searched to obtain the current standard load parameters of each carrier / container; The actual load ratio of the vehicle / container is calculated based on the on-site image evaluation. For example, when a cart enters the material yard with an empty bucket and stops to wait for materials to be taken, the depth of the bucket occupies m1 pixels on the image. When the materials are taken, the depth of the empty bucket occupies m2 pixels on the image. The actual load ratio is (m1-m2) / m2.

[0052] The material usage is calculated based on standard load parameters, actual load ratio, and the types and quantities of carriers / containers on site to generate material usage data.

[0053] According to the above settings, the method can directly analyze the material usage of materials such as cement and bricks through image recognition, and vice versa for storage. The second setting allows staff to avoid installing weighbridges at the entrances and exits of each material yard and storage warehouse, which reduces the application cost.

[0054] In another embodiment of the method, if cost is not a consideration, floor scales can be installed at the entrances and exits of all material yards and storage warehouses. At this time, if the materials taken meet the preset unit measurement conditions, the weight of the carrier / container when entering and exiting can be directly measured by the floor scale and compared, similar to the first case, and the database can be updated.

[0055] Regarding the above-mentioned calculation of the actual load ratio of the carrier / container based on the on-site image evaluation, in another embodiment of the present application, it includes: Based on the on-site images, identify the first time a carrier / container takes materials from a site; Track the first material retrieval behavior, determine the material landing point (determine the location of the holding cavity), and identify the initial empty rate of the analysis carrier / container; Based on the on-site images, identify the last loading behavior of the carrier / container in and out of the site, and identify and analyze the corresponding current vacancy rate; The actual load ratio is calculated based on the initial vacancy rate and the current vacancy rate.

[0056] The purpose of the above arrangement is to prevent misjudgment caused by the vehicle / container initially being loaded with goods, and the implementation of the arrangement can be reflected in the examples of the aforementioned embodiments.

[0057] The embodiment of the present application also discloses a material tracking system based on a BIM parametric model.
