Description

Technical Field

[0001] The present invention relates to the technical field of network statistics and data visualization, and in particular to a BIM model generation method, device and medium based on passenger flow of a terminal building. Background Art

[0002] Current approaches to modeling passenger flows at airport terminals have the following limitations: (1) Designer’s limitations The creation of the passenger flow model and the calculation of facilities in the terminal building rely on the designer's understanding of the passenger flow in the terminal building and the mastery of architectural design knowledge. However, this method has high requirements on the quality of the designer, and due to the different understanding and experience of each designer, the final design of the terminal building may deviate from the actual needs.

[0003] (2) Facility Update The requirements for passenger flow in terminals are constantly updated over time and with the technological advancement of facilities and equipment, which makes it difficult for designers to grasp the latest process requirements and equipment parameters in a timely and accurate manner, resulting in a mismatch between design results and the latest passenger flow needs.

[0004] (3) Duplication of preliminary design work Each design project requires repeating the same design process, which makes the work highly cumbersome and requires a lot of time and energy investment.

[0005] (4) The workload of connecting with different airports in the later stage is large and repetitive Each airport has its own demands for the ratio of facilities and equipment based on its own staffing requirements, and the demands of each airport may be constantly adjusted according to policies, personnel, etc., which results in a large workload and repeated designs, requiring designers to invest a lot of time and energy. Summary of the invention

[0006] The method of the present invention innovates the design method of terminal processes, transforming the traditional method that relies on a single designer into a standardized and callable design method, proposes a BIM model generation method, equipment and medium based on terminal passenger flow, and designs a standardized and callable design method according to the classification of terminals according to annual passenger throughput.

[0007] In order to achieve the above objectives, the following technical solutions are proposed: The BIM model generation method based on the passenger flow of the terminal includes the following steps: Step 1: Classify the terminals by annual passenger throughput; Step 2: Determine the plane area distribution of the terminal building. For each area, classify the terminal building according to the annual passenger throughput, and design the BIM model of each area. The design of the BIM model of each area includes determining the number of standard BIM models corresponding to the equipment according to the annual passenger throughput; Step 3: Number the completed standard BIM models according to the categories of the terminal buildings and store them in the BIM model library; Step 4: Retrieve and call the BIM models of each area in the BIM model library according to the project design requirements to complete the design of the terminal building BIM model.

[0008] As a preferred solution, in step 1, the terminals are divided into 9 categories according to the annual passenger throughput, including annual passenger throughput less than 500,000, annual passenger throughput greater than or equal to 500,000 and less than 2 million, annual passenger throughput greater than or equal to 2 million and less than 5 million, annual passenger throughput greater than or equal to 5 million and less than 10 million, annual passenger throughput greater than or equal to 10 million and less than 15 million, annual passenger throughput greater than or equal to 15 million and less than 25 million, annual passenger throughput greater than or equal to 25 million and less than 40 million, annual passenger throughput greater than or equal to 40 million and less than 70 million, and annual passenger throughput greater than or equal to 70 million.

[0009] As a preferred solution, step 2 specifically includes the following steps: Dividing the terminal into different areas, including the departure hall, departure domestic security screening area, domestic terminal area, domestic baggage claim hall, departure international joint inspection area, international terminal area, international arrival joint inspection area, international baggage claim hall and transfer area; For each area, determine the functional modules of each area according to the regional functions, and build a standard BIM model of the equipment in the functional modules; Calculate the number of standard BIM models of equipment in the functional module based on the annual passenger throughput.

[0010] As a preferred solution, the method of calculating the number of standard BIM models of equipment in the functional module according to the annual passenger throughput specifically includes the following steps: Calculate peak hours based on annual passenger throughput; Calculate the number of manual devices based on peak hours, percentage of self-service devices, and manual device passing time; Calculate the number of self-service devices based on peak hours, self-service device ratio, and self-service device pass time; Determine the ratio of manual and self-service equipment based on the number of manual equipment and the number of self-service equipment, and determine the number of standard BIM models of equipment in the functional module based on the ratio of manual and self-service equipment.

[0011] As a preferred solution, in step 2, for the departure international joint inspection area module, the number of standard BIM models of border inspection equipment is determined including the following calculation process: The formula for calculating peak hours is: Peak hour number = INT((((International annual passenger throughput × 10,000) / 365) / 24) × 4); Number of border inspection manual equipment = INT((((number of people in peak hours × 0.6) × (1-proportion of border inspection self-service equipment)) × time of border inspection manual equipment passing) / (20 × 60)) + 1; Border inspection self-service equipment = INT ((((peak hourly number of people × 0.6) × border inspection self-service equipment ratio) × border inspection self-service equipment passing time / (20 × 60)) + 1; Among them, the INT() function is an integer function.

[0012] As a preferred solution, the ratio of self-service border inspection equipment is in the range of 0.3 to 0.8, and the ratio of self-service border inspection equipment is related to the annual passenger throughput.

[0013] As a preferred solution, the proportion of self-service border inspection equipment is: Applicable to airports with an annual passenger throughput of less than 2 million and a proportion of 0.3% of self-service border inspection equipment; Applicable airports have an annual passenger throughput of 2 million or more and less than 10 million, and the proportion of self-service border inspection equipment is 0.4; Applicable airports have an annual passenger throughput of 10 million or more and less than 25 million, and the proportion of self-service border inspection equipment is 0.5; Applicable airports have an annual passenger throughput of 25 million or more and less than 40 million, and the proportion of self-service border inspection equipment is 0.6; Applicable airports have an annual passenger throughput of 40 million or more and less than 70 million, and the proportion of self-service border inspection equipment is 0.7; Applicable airports have an annual passenger throughput greater than or equal to 70 million, and the proportion of self-service border inspection equipment is 0.8.

[0014] As a preferred solution, step 4 specifically includes: Determine the size of each area in the plane terminal building based on the number of standard BIM models of the equipment; Import the standard BIM model of the equipment into each area according to the pre-calculated quantity to form the BIM functional module of each area; Connect the BIM functional modules of each area to build a complete BIM model of the terminal.

[0015] Based on the same concept, the present invention also proposes a BIM model generation device based on terminal passenger flow, including at least one processor and a memory communicatively connected to the at least one processor; the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute any of the above-mentioned BIM model generation methods based on terminal passenger flow.

[0016] Based on the same concept, the present invention also proposes a storage medium, in which instructions executable by a processor are stored.

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with test examples and specific implementation methods. However, this should not be understood as the scope of the above subject matter of the present invention being limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0020] Example 1 A BIM model generation method based on terminal passenger flow, the flow chart is as follows Figure 1 As shown, the following steps are included: Step 1: Classify the terminals by annual passenger throughput.

[0021] Terminal throughput is one of the core indicators for measuring airport business volume. In order to propose different requirements for the planning and design of different passenger terminals, such as area standards, facility configuration standards, etc., passenger terminals are classified and classified. Different planning and design standards and facility configuration requirements are formulated for different levels to adapt to different passenger capacities and meet the needs of corresponding service levels.

[0022] According to the annual passenger throughput of the airport, civil airports are divided into four levels. The annual passenger throughput level classification table of civil airports is shown in Table 1: Table 1 Classification of annual passenger throughput of civil airports Civilian Airport Level Annual passenger throughput (10,000 people) Level 1 ≥4000 Level 2 1500~＜4000 Level 3 200~＜1500 Level 4 ＜200 Airport security is divided into four levels, as shown in Table 2: Table 2 Airport security level classification table Airport security level Annual passenger throughput (10,000 people) Level 1 ≥1000 Level 2 200~＜1000 Level 3 50~＜200 Level 4 ＜50 According to experience, small airports tend to have a relatively high concentration rate. Based on the classification of annual passenger throughput levels at civil airports and the classification of airport security levels, the terminals with annual passenger throughput are classified, and the classification results are as follows: (1) Annual passenger throughput is less than 500,000 (2) Annual passenger throughput: 500,000 to 2 million (3) Annual passenger throughput 2-5 million (4) Annual passenger throughput 5-10 million (5) Annual passenger throughput 10-15 million (6) Annual passenger throughput 15-25 million (7) Annual passenger throughput 25-40 million (8) Annual passenger throughput 40-70 million (9) Annual passenger throughput is greater than 70 million The annual passenger throughput can also be further subdivided to obtain a more accurate design module. The number of equipment in each area will be determined based on the annual passenger throughput.

[0023] Step 2: Determine the regional distribution of the plane terminal. For each region, design the BIM model of each region according to the classification of the terminal by annual passenger throughput. The design of the BIM model of each region includes determining the number of standard BIM models corresponding to the equipment according to the annual passenger throughput.

[0024] The terminal design concept of the present invention is from overall design to partial design and then to overall combination, that is, first, determine the areas that the terminal has, and the terminal is divided into different areas, including ① departure hall, ② departure domestic security inspection area, ③ domestic waiting area, ④ domestic baggage claim hall, ⑤ departure international joint inspection area, ⑥ international waiting area, ⑦ international arrival joint inspection, ⑧ international baggage claim hall, ⑨ transit area. According to different passenger scales, ⑤⑥⑦⑧⑨ may not exist. Then carry out partial design of each area, calculate the number of standard BIM models of equipment in each area according to the annual passenger throughput, and determine the area of ​​the area according to the data of the standard BIM model of equipment. Finally, after the BIM model of each area is designed, the BIM model of each area is connected in series according to the design process to combine into the final terminal model.

[0025] In the above concept, it is an important step to calculate the number of standard BIM models of equipment in each area based on the annual passenger throughput. For each type of terminal corresponding to the annual passenger throughput, the peak hour number of the terminal is inferred based on the passenger volume and concentration rate of the terminal. The number of equipment is calculated based on the processing capacity of each device, and then based on the passenger queuing requirements, the size of the functional module of each area can be calculated. At the same time, according to the relevant recommendations of the International Air Transport Association (IATA), the area of ​​the area is reviewed, and there is a basic unit module of the site size that matches the various processes of the terminal throughput. The modules are in various forms, and a database of passenger volume classification and corresponding modules for each area is established. Different modules can be called for different plane layouts. This module needs to be continuously supplemented and improved to obtain a more accurate solution layout.

[0026] Here we take the international departure border inspection area module as an example: According to IATA specifications, the number of check-in passengers is calculated based on the number of border inspection channels and the number of passengers during peak hours. The number of people passing through each border inspection channel per hour is certain. The more people there are during peak hours, the more border inspection channels are needed. The waiting time for passengers should not be too long, so it is necessary to calculate the appropriate number of check-in passengers. The number of people queuing for border inspection is then calculated based on the number of check-in passengers, and the final demand for border inspection equipment is finally calculated based on the equipment processing time. This process is too cumbersome to calculate, and there are multiple assumptions. With the advancement of technology, passengers can check in electronically, and the check-in time is inaccurate. Border inspection equipment is also constantly being updated, with manual equipment and self-service equipment, and the inspection time is also different. The original specifications are no longer applicable. Therefore, the number of equipment is directly obtained through the peak hour number of people and the passing time of the equipment in a simplified way. Through calculation, the number of facilities under different equipment ratios is obtained.

[0027] The calculation process of border inspection equipment is as follows: Peak hour number of people = INT((((International annual passenger throughput (10,000 people)*10,000) / 365) / 24)*4) Border inspection manual equipment (unit) = INT(((((peak hour number of people (people) * 0.6) * (1-border inspection self-service equipment ratio)) * border inspection manual equipment passing time (s)) / (20 * 60)) + 1 Border inspection self-service equipment (number) = INT((((peak hour number of people (people) * 0.6) * border inspection self-service equipment ratio *) border inspection self-service equipment passing time (s)) / (20*60))+1 Among them, the INT() function is an integer function, the unit of international annual passenger throughput is 10,000 people, the unit of peak hour passenger volume is person, the unit of self-service border inspection equipment passing time and manual border inspection equipment passing time is second (s), and the proportion of self-service border inspection equipment is a percentage value less than 1.

[0028] The proportion of self-service border inspection equipment is divided according to the experience of the connecting airports. Each airport has different proportions of self-service equipment according to its own personnel configuration, site conditions, and proportions of self-service equipment.

[0029] Self-service equipment has a fast passing time and occupies little space. First, according to the site requirements, if there is insufficient space, try to adopt a solution with a higher proportion of self-service equipment (usually for reconstruction projects). If there is sufficient space, the proportion needs to be determined according to the border inspection department, and this proportion is designed according to the border inspection requirements of different airports (usually for new projects).

[0030] Self-service devices can achieve fast and accurate passenger identification and information matching through technologies such as facial recognition and intelligent recognition, providing passengers with more convenient and personalized services, thereby improving the service experience.

[0031] The proportion of self-service equipment in large airports is usually higher. Large airports usually have a large passenger throughput. Self-service equipment can significantly reduce the waiting time of passengers and improve the operating efficiency of the airport. The flight situation at large airports is usually complex and changeable. Self-service equipment can achieve rapid response and adjustment through intelligent management. Real-time update of flight information provides passengers with accurate flight dynamics and follow-up services. Self-service equipment can significantly reduce the airport's manpower requirements and reduce labor costs. It can also provide 24-hour uninterrupted service.

[0032] The proportion of self-service border inspection equipment is matched with the annual passenger throughput to form Table 3, so as to quickly determine the number of self-service equipment.

[0033] Table 3 Correspondence between the proportion of self-service border inspection equipment and the annual passenger throughput of applicable airports Proportion of self-service border inspection equipment 0.3 0.4 0.5 0.6 0.7 0.8 Applicable airport annual passenger throughput ≤2 million people 2-10 million people 10-25 million people 25-40 million 40-70 million ≥70 million people Establish a corresponding model library according to the number of facilities under the equipment ratio, such as Figure 2 As shown in the figure, the proportion of self-service border inspection equipment in the border channel module ranges from 0.3 to 0.6. The border inspection modules corresponding to different international passenger volumes are obtained based on the proportion of self-service border inspection equipment.

[0034] Other areas also follow the design logic of the international departure border inspection area module to obtain the corresponding relationship between passenger volume and modules. Taking the passenger check-in hall with an annual passenger throughput of less than 500,000 as an example, the above formula is used to calculate the value range of the check-in module ratio in the check-in hall, and the corresponding check-in hall module is obtained based on the value range of the check-in module ratio.

[0035] Other public areas that can be used for this idea mainly include: passenger check-in hall, domestic passenger departure security check area, domestic passenger waiting area, domestic passenger arrival baggage claim area, international passenger departure joint inspection area, international passenger waiting area, international passenger arrival baggage claim area, reception hall, international to domestic transit area, and domestic to international transit area.

[0036] With the construction of the BIM model modules of the aforementioned areas, the plane layout of each area can be given. Due to the complex process and diverse configurations of the terminal building, different plane layouts can be arranged under the same module according to different flow organizations.

[0037] The schematic diagram of the overall concept of module 1 in the passenger check-in hall is as follows Figure 3 shown.

[0038] Furthermore, after determining the BIM models of each area, it is necessary to connect the BIM models of each area in series. Taking the domestic departure process as an example, the international departure process is: international check-in → international joint inspection → international waiting area. Select the appropriate functional modules in steps 1 and 2 to connect the processes in series.

[0039] The streamline is fixed. The modules of each area are sorted and classified with reference to the border inspection module, and then each module is connected in series. Taking the domestic departure process as an example, the order of connection is: domestic check-in → domestic security check → domestic waiting area. Find the corresponding block corresponding to the annual throughput and then connect it in series.

[0040] In addition, the ratio of manual and self-service equipment is in a dynamic development stage according to the staffing of different airport terminals and the continuous updating of equipment. In order to adapt to the development, different ratios of manual and self-service equipment are arranged in the module, and the equipment ratio can be adjusted at any time in the future to meet the different needs of each airport.

[0041] Take international joint inspection as an example: the process is customs quarantine → international security inspection → customs → border inspection. Among them, the equipment with manual and self-service ratio is mainly border inspection. Select the required ratio of manual and self-service equipment, and adjust the ratio of manual and self-service equipment as the dynamic changes in use. The schematic diagram of the border inspection module design idea of ​​international joint inspection is shown in the figure. Figure 4 shown.

[0042] Step 3: Number the completed standard BIM models according to the terminal classification and store them in the BIM model library. Taking the annual passenger throughput of less than 500,000 as an example, the model architecture is as follows: Figure 5 shown.

[0043] Step 4: Retrieve and call the corresponding standard BIM model according to the project design task requirements. Perform in-depth design of the project based on the called standard BIM model.

[0044] According to different project conditions, the corresponding modules are selected in stages. For example, for airports with a passenger throughput of less than 500,000 people and no international section, the check-in hall, domestic passenger security check area, domestic passenger waiting area, domestic passenger arrival baggage claim area, and reception hall modules in the model library need to be called up, and the functional blocks are connected in series according to the functional processes, and then the matching layout is selected according to the passenger flow.

[0045] Step 5: According to the design specifications, terminal process development, and passenger clearance facility and equipment updates, formulate a standard BIM model update and maintenance plan, and conduct regular and irregular unified updates and maintenance of the terminal passenger process standard BIM model library.

[0046] The model library is constantly updated, subdivided and optimized: for example, the annual passenger throughput of 8-15 million is subdivided into annual passenger throughput of 8-12 million and 12-15 million; the international departure joint inspection is further subdivided into customs quarantine, international security inspection, customs, and border inspection; the types of modules in different areas are constantly supplemented; the layout of different modules is constantly supplemented; the facilities and equipment in each functional area are constantly updated according to the data provided by the manufacturer, and the model library is constantly improved.

[0047] The advantages of the present invention are as follows: 1. The annual passenger throughput of the terminal is an important factor affecting the design of the terminal. The annual passenger throughput of the terminal determines which large model blocks are selected in step 1, the module layout in step 2, and the process model in step 3. The classification method in step 1 corresponds to the characteristics of the standard BIM model, matches the relevant building specifications and the passenger process technology requirements of the terminal, and ensures the accuracy of calling the terminal BIM model in the design work.

[0048] Select the model block according to the annual passenger throughput. Taking the supplementary border inspection as an example, different model blocks corresponding to the annual passenger throughput are available. After the terminal process is determined, the corresponding module can be found. If the annual passenger throughput is known, the number of modules can be determined. Then, each module can be inserted according to the terminal process, which reduces the design time and improves the design efficiency. At the same time, the model block is constantly updated, which can respond to the changes in the process and technological requirements of the terminal in a timely manner, thereby ensuring the timeliness and quality of the design results. It avoids the personalized understanding of the process and technological process of the terminal. Through the joint decision-making and establishment of the model library by the technical team, the design results are unified and standardized while maintaining flexibility. It changes the form of technical training for designers. Through standardized and callable design methods, designers can master new technologies and knowledge more quickly, shortening the technical maturity cycle of designers. By directly calling the corresponding BIM model results, the repeated design process of analysis, decision-making, and drawing of the process and technological requirements of the project terminal is skipped, further shortening the design cycle and significantly improving the design efficiency and design quality. According to the different requirements of the configuration of facilities and equipment at each airport, the corresponding BIM model is called to reduce the time and energy invested by designers.

[0049] The standard BIM model storage in step 3 must be stored by "classification" number, and there is only one corresponding relationship between the number and the model to ensure the accuracy of model calling.

[0050] Step 4: In the in-depth design process based on the standard BIM model, there is no need to adjust the process requirements of the terminal building that have been designed in the model. The in-depth design content is mainly for the parts that are not involved in the model. This not only reduces the high requirements for the personal qualities of architects in traditional design, but also significantly improves the design efficiency, while avoiding subjective errors caused by individual differences among designers, and greatly improves the design quality.

[0051] The unified maintenance of step 5 ensures that the BIM model can be timely matched with relevant specifications, changes in terminal process and technology requirements, and updates of facilities and equipment, thereby improving the accuracy of the terminal building design results.

[0052] Example 2 The present invention establishes a terminal standard BIM model library based on the terminal process technology requirements, which mainly includes: 1. Classify by terminal passenger throughput, and infer the peak hour number of passengers based on the terminal passenger volume and concentration rate (or directly obtain the peak hour number of passengers through research).

[0053] First, the terminal is divided into different areas, including ① departure hall, ② departure domestic security area, ③ domestic waiting area, ④ domestic baggage claim hall, ⑤ departure international joint inspection area, ⑥ international waiting area, ⑦ international arrival joint inspection, ⑧ international baggage claim hall, ⑨ transfer area. Depending on the size of the passenger volume, ⑤⑥⑦⑧⑨ may not be there.

[0054] The number of devices is then calculated based on the processing capacity of each device, and the size of the functional modules in each area is then calculated based on the passenger queuing needs. At the same time, the area of ​​the area is reviewed based on the relevant recommendations of the International Air Transport Association (IATA). In this way, there are basic unit modules with the size of the site for each process that matches the terminal throughput. The modules come in various forms, and a corresponding database is established for passenger volume classification and corresponding modules for each area.

[0055] 2. Based on the basic unit modules, various terminal process standard BIM models that can meet the building specifications and passenger process technology requirements are arranged.

[0056] 3. Then, according to different functional areas, the standard BIM model process of the terminal process is supplemented: ① domestic departure, ② domestic arrival, ③ international departure, ④ international arrival, ⑤ international to domestic connecting flight transfer area, ⑥ domestic to international connecting flight transfer area, and several main components. Depending on the passenger scale, ③④ and ⑤⑥ may not be present.

[0057] 4. Facility modules equipped with different equipment can be selected according to the different needs of each airport.

[0058] 5. The result of this method is a BIM model, which can be directly used in the forward BIM design of the terminal building. There is no need to adjust the terminal process technology that the model has already responded to. It can achieve rapid design and automatic drawing.

[0059] 6. Numbering, storage, retrieval and calling are completed on a unified BIM modeling software platform. It is easy to use and highly accurate.

[0060] 7. The terminal building process standard BIM model library is updated and maintained in a timely manner by a professional team. The technical standards are unified to efficiently respond to changes in terminal building process technology and facility equipment upgrades.

[0061] Example 3 Take a terminal building as an example to explain the technical solution: Step 1: Determine the terminal configuration.

[0062] A terminal building configuration such as Figure 6 As shown, the case classification is - terminal with an annual passenger throughput of 23 million. According to the classification, select the check-in hall module, domestic security inspection module, domestic waiting module, domestic baggage claim module, international joint inspection module, international waiting module, international baggage claim module, reception hall module, international to domestic module, and domestic to international module that meet the requirements.

[0063] Step 2: Filter the required functional modules and select the modules that meet the terminal building configuration. The modules are arranged in different ways for use. For example, the modules selected include check-in, quarantine, security, customs, and border inspection. The schematic diagram of the selected modules is as follows: Figure 7 shown.

[0064] Step 3: Select the required process as required: International Departure, International Arrival, Domestic Departure, Domestic Arrival, International to Domestic Transfer, Domestic to International Transfer.

[0065] Taking international departures as an example: The international departure process is: ① International check-in → International joint inspection (② Customs quarantine → ③ International security inspection → ④ Customs → ⑤ Border inspection) → ⑥ International waiting area. In step 1, select the appropriate function module to connect the process in series. The schematic diagram of the international departure process is as follows Figure 8 Finally, select the appropriate floor plan in step 2 to connect the processes in series.

[0066] Step 4: According to the "BIM model of each area", design and make different proportion configuration models of manual and self-service equipment corresponding to passenger throughput. This step can be used in conjunction with various needs of the user department later. The manual and self-service ratio can be set to 2:1, 1:1, etc. The manual and self-service ratio diagram is as follows Fig. 9 shown.

[0067] Step 5: Number the completed standard BIM model by "classification" and store it in the BIM model library.

[0068] Step 6: Retrieve and call the corresponding standard BIM model according to the project design task requirements.

[0069] Each area is designed in this way to obtain the overall model.

[0070] Finally, it should be noted that the embodiments described in detail above are only the best practices of the invention and cannot be used to limit the scope of rights of the invention. Equivalent replacement of the technical solutions recorded in the aforementioned embodiments does not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the invention, and they should all be included in the scope of the claims and description of the invention.
