JP7701807B2 - Elevator planning support device and elevator planning support method - Google Patents

Description

The present invention generally relates to technology that assists in elevator installation planning.

For customers and engineers in remote locations, creating a shared 3D space between devices connected via a network and sharing 3D models of the building being designed, elevator landings, and the people who will use the space, as well as models of the elevators, is important in sharing issues when planning elevator installation.

In the system of Patent Document 1, multiple users share a virtual three-dimensional space, and each user manipulates a three-dimensional model in the three-dimensional space and accesses detailed explanatory information about the three-dimensional model. This provides technical support.

The system in Patent Document 2 records the viewpoint and viewpoint movement history when projecting a shared virtual three-dimensional space and a three-dimensional model placed in that space onto a monitor, and collects data and display history. This makes it possible to obtain viewpoints that interest users most.

Japanese Patent Application Publication No. 10-91057 JP 2020-13466 A

Patent Document 1 assumes that users share a three-dimensional space at the same time and information, and has the problem that it is difficult to grasp the interests of many users at the same time.

The viewpoints that interest users, as disclosed in Patent Document 2, are expressed by viewpoints in three-dimensional space and their display information, but because they are images or numerical data, there is a problem in that it is difficult to grasp what interests the user when the target model becomes complex. In particular, in CAD in the design process of a building, three-dimensional models of floors, walls, elevators, etc. are often expressed with standard materials (textures), making recognition even more difficult.

The elevator planning support device performs log analysis for each of a plurality of users based on simulation data (data including data showing the results of simulating the flow of people in a building and data on a three-dimensional model composed of multiple submodels) and operation log data (data including operation logs for each user operation on a three-dimensional model screen displayed on a user terminal based on the simulation data), including detecting user interests including submodels showing the interests of the user of the user terminal with respect to elevators in a building corresponding to the simulation data and the level of interest in the interests, generates data for an administrator which is data showing the aggregated results or statistics of the user interests of the plurality of users, and provides the data for an administrator to the administrator terminal.

The present invention makes it easy to identify the interests of each of multiple users and visualize the identified interests of multiple users.

An elevator planning support device according to an embodiment of the present invention will be described below with reference to the drawings.
<Configuration of the elevator planning support device>

Figure 1 shows the configuration of an elevator planning support device according to one embodiment of the present invention. The overall configuration of the elevator planning support device 50 will be explained using Figure 1.

In this embodiment, the elevator planning support device 50 is a physical device (typically a computer) that has physical computing resources such as an interface device 181, a storage device 182, and a processor 183 connected to them, but it may also be a logical device based on the physical device (for example, a device serving as a cloud computing service).

The interface device 181 communicates with the user terminal 102 of the user 110 and the administrator terminal 112 of the administrator 111, for example, via a communication network. The "user" may be someone on the building side, for example, someone from a company constructing the building, or the building owner. The "administrator" may be someone providing elevator planning support, for example, someone from an elevator manufacturer, or a CAD vendor providing a 3D model. The "user" and the "administrator" may be the same person or someone from the same company. Each of the user terminal 102 and the administrator terminal 112 may be an information processing terminal (for example, a personal computer or a smartphone) equipped with an input/output device including a display device.

The storage device 182 includes a simulation storage 121 in which simulation data including data representing the results of a simulation evaluating an elevator installation plan (results of simulating the flow of people in a building) is stored, an operation log storage 122 in which operation log data including operation logs for each user operation is stored, and an analysis result storage 123 in which data representing user interests obtained by log analysis, which will be described later, is stored. The "simulation data" also includes data of a three-dimensional model composed of multiple submodels. A "user operation" is an operation performed by the user 110 on the screen of a three-dimensional model displayed on the user terminal 102 based on three-dimensional data (data based on simulation data and data of a three-dimensional model composed of multiple submodels). In this embodiment, "storage" refers to a storage area based on the storage device 182.

The processor 183 executes the computer program to realize the user providing unit 101, the log analysis unit 103, and the administrator providing unit 104. Details of these functions 101, 103, and 104 will be described later.

This concludes the explanation of the configuration of the elevator schedule support device 50.
<Data Description>

An example of simulation data will be described with reference to FIG. 7. The simulation data here is displayed using, for example, JSON (JavaScript Object Notation), and has a hierarchical data representation as shown in FIG. 7. That is, FIG. 7 shows simulation data 10000 illustrating a structure equivalent to the JSON structure.

First, in the simulation data 10000, information 11000 is information about all floors of a building, and can include information about multiple floors, such as information about the first floor 11100 and information about the second floor 11200. The information about each floor may further include information about the shape to be displayed on the screen.

Next, in the simulation data 10000, information 12000 is information about all people moving within the building, and can have information about multiple people, such as information 12100 about person "Person 1," information 12200 about person "Person 2," and information 12300 about person "Person 3." For example, information 12100 about person "Person 1" has information about the departure point (Origin) 12110 and the destination (Destination) 121200.

In particular, information about people also includes information about changes in status over time. For example, information 12100 about person "Person1" includes information about changes in time 12130, which indicates changes in status in units of seconds, such as information 12131 indicating the status at 8:30:00 and information 12132 indicating the status at 8:30:01. A person's status at each time may be defined by elements such as location, direction of movement, speed of movement, and waiting time. Based on such information about changes in status over time, the user providing unit 101 searches for the status at the time requested by the user 110, and displays the status on the screen 131 displayed on the user terminal 102.

Next, in simulation data 10000, information 13000 is information on all elevator groups in a building, and can include information on multiple elevator groups, such as shuttle elevator information 13100 and high-rise elevator information 13200. The information on each elevator group includes information on specifications. For example, shuttle elevator information 13100 includes specification information 13110, which may include information such as number of cars information 13111, rated speed information 13112, and capacity information 13113.

Like people information, elevator information also includes information on changes in status over time. Taking shuttle elevator information 13100 as an example, status information 13120 includes information 13121 that represents the status at 8:30:00, information 13122 that represents the status at 8:30:01, and information 13123 that represents the status at 8:30:02. Based on this information on changes in status over time, user providing unit 101 searches for the status at the time requested by the user, and displays the status on screen 131 displayed on user terminal 102. Time may be expressed in units of year, month, day, hour, minute, and second, or in finer or coarser units than these. This concludes the explanation of Figure 7.

Using Figure 6, we will explain the overview of the sub-models that the 3D model has.

In addition to the data shown in FIG. 7, the simulation data includes three-dimensional model data. The three-dimensional model is a building model 700. The building model 700 includes an elevator hall submodel 701 and an elevator hall submodel 702. A submodel is a part of a three-dimensional model, and in the example shown in FIG. 6, a submodel is a model contained in any partial space of the three-dimensional model. As will be described later, it is easy to detect submodels displayed on the screen displayed on the user terminal 102, and objects of interest are detected on a submodel basis, making it easy to detect objects of interest. This concludes the explanation of FIG. 6.

An overview of the history of the user's screen display will be described with reference to FIG. 8. The data of the history of the screen display may be, for example, data included in the operation log data. As the history of the screen display, information such as an ID and a file path that uniquely identify the three-dimensional model to be displayed, and viewpoint information used for the screen display are used. In this embodiment, as the information of the user's screen display, information on the size of the screen display is also saved, for example, by the user providing unit 101. Next, the three-dimensional coordinates (X, Y, Z) of the reference position 610 of the viewpoint are recorded by the user providing unit 101, and information (X, Y, Z) that specifies the three-dimensional coordinates of the focal position 620 as the direction of the viewpoint from the reference position 610 of the viewpoint is saved by the user providing unit 101. To determine the viewpoint in the three-dimensional space, an angle for determining the vertical direction of the viewpoint is required, but since the vertical direction may always be fixed in the application of this embodiment, it is omitted. As another example, the direction of the viewpoint may be specified by the azimuth angle 604 and the elevation angle 605 without specifying the focal position. Note that all three-dimensional coordinates are either the same as the coordinate system of the model, or are coordinate systems that can be uniquely transformed into the coordinate system of the model. This concludes the explanation of Figure 8.

The operation log data will be described with reference to FIG. 12, which shows an example of operation log data collected by the user providing unit 101 and stored in the operation log storage 122. The operation log data is, for example, data in a table format. The operation log data has a record for each user operation (or for each fixed time), and each record includes information such as a display date and time 1201 indicating the date and time when the screen was displayed by the user, a display target date and time 1202 indicating the date and time of the simulation result to be displayed, a three-dimensional model 1203 indicating the name of the object (e.g., a building) corresponding to the three-dimensional model to be displayed, a user 1204 indicating the ID of the user who displayed the screen, a viewpoint position 1205 indicating the coordinates of the viewpoint position of the screen display, a focus position 1206 indicating the coordinates of the focus position indicating the direction of the viewpoint of the screen display, and a screen size 1207 indicating the size of the screen 131. Records 1211 and 1212 show operation logs for the screen display of the same user "User1", but the display target date and time have changed. Record 1213 shows an operation log of a different user "User2". This concludes the explanation of Figure 12.

The analysis result data will be described with reference to FIG. 9, which shows an example of the analysis result data calculated by the log analysis unit 103 and stored in the analysis result storage 123. Here, the analysis result data is, for example, data in a table format. The analysis result data has a record for each log analysis result (or for each fixed time period), for example, and each record includes information such as a display date and time 901 indicating the date and time when the screen was displayed by the user 110, a display target date and time 902 indicating the date and time of the simulation result to be displayed, a three-dimensional model 903 indicating the name of an object (for example, a building) corresponding to the three-dimensional model to be displayed, a sub-model 904 indicating the name of a sub-model detected as an object of interest in the three-dimensional model, a user 905 indicating the ID of the user who performed the screen display, and an interest level 906 indicating the calculated interest level. The log analysis, including the calculation of the interest level, is performed by the log analysis unit 103, but data required for the log analysis can be obtained from the operation log storage 122 and the simulation storage 121.

Records 911 and 912 are the saved analysis results of the screen display of the same user "User1" at the same time, and specifically, are calculated from record 1211 shown in FIG. 12. In record 911, the interest level in shuttle elevators is 50%, whereas in record 912, the interest level in high-rise elevators is 5%.

Records 913 and 914 are also the stored analysis results of the screen display of the same user "User1" at the same time, and specifically, are calculated from record 1212 shown in FIG. 12. In record 913, the interest level in shuttle elevators is 45%, while in record 914, the interest level in high-rise elevators is 7%. Record 915 shows interest level data for a different user, "User2." This concludes the explanation of FIG. 9.
<Processing Description>

Next, the flow of display on the user terminal 102 and collection of operation logs from the user terminal 102 will be explained using FIG. 2.

The user providing unit 101 acquires the simulation data to be displayed from the simulation storage 121 (see reference numeral 201) and distributes it to the user's terminal 102 (see reference numeral 202). The user terminal 102 displays a screen 131 on which a three-dimensional model and an animation of people's flow based on the distributed simulation data are displayed. Depending on the user's operation on the screen 131, it is possible to change the viewpoint from which the three-dimensional model is displayed or to change the time of the displayed simulation result. The user providing unit 101 collects an operation log including information indicating the display on the screen 131 from the user terminal 102, and the user providing unit 101 stores the operation log in the operation log data of the operation log storage 122 (see reference numeral 203). Details of the operation log are as described with reference to FIG. 12. This concludes the description of FIG. 2.

Next, we will use Figure 3 to explain the flow of log analysis and visualizing the log analysis results to the administrator.

The log analysis unit 103 acquires simulation data from the simulation storage 121 (see reference numeral 204), extracts a three-dimensional model of the building to be displayed, acquires operation log data from the operation log storage 122 (see reference numeral 205), and restores the screen 132 (specifically, the three-dimensional model display on the screen, the flow of people, and the transition of user operations on the screen) previously displayed by the user terminal 102 of the user 110. The log analysis unit 103 performs log analysis including detecting user interests including a sub-model representing an interest target of the user 110 of the user terminal 102 with respect to an elevator in a building corresponding to the three-dimensional model and a level of interest in the interest target from the restored screen 132. The log analysis is performed for each user. The log analysis result for each user is stored in the analysis result storage 123 by the log analysis unit 103 (see reference numeral 206). For example, the detected interest target may be an object represented by a sub-model that is displayed on the screen 132 in a certain proportion or more of the three-dimensional model in terms of area or time. The interest level may be detected, for example, as follows. That is, the log analysis unit 103 may calculate at least one of the following values (A) and (B) for the detected sub-model (interest subject), and calculate the interest level of the detected interest subject based on the calculated value. In this way, it is expected that the user's interest subject and interest level can be detected with high accuracy.
(A) The ratio of the display area of the sub-model to the area of the screen 132.
(B) The proportion of time that the sub-model was displayed on the screen 132 relative to the time that the screen 132 was displayed.

This concludes the explanation of Figure 3.

The details of the log analysis process will be explained using Figure 10. In the following explanation, steps will be abbreviated as S.

In S1, the log analysis unit 103 obtains from the operation log storage 122 the ID (identification information) of the three-dimensional model displayed on the screen of the user terminal and information on the viewpoint of the screen display.

In S2, the log analysis unit 103 obtains the 3D model using the ID of the 3D model.

In S3, the log analysis unit 103 obtains a coordinate transformation matrix from the viewpoint information acquired in S1. This coordinate transformation matrix is generally known as an MVP matrix, and is calculated by multiplying a model coordinate transformation matrix for reflecting the position and scale of the three-dimensional model itself, a view coordinate transformation matrix based on the viewpoint in three-dimensional space, and a projection matrix for projecting data in three-dimensional space onto a two-dimensional screen for display on the screen. Note that if the coordinates of the three-dimensional model itself are expressed in advance as coordinates in three-dimensional space (world coordinate system), there is no need to multiply by the model coordinate transformation matrix.

In S4, the log analysis unit 103 multiplies the 3D model obtained in S2 by a coordinate transformation matrix to obtain the 3D model visible from the viewpoint position.

In S5, the log analysis unit 103 draws each of the submodels included in the three-dimensional model obtained in S4, identifies the submodels to be displayed on the screen, determines the drawn area (number of pixels) for each identified submodel, and calculates the ratio of the determined area to the screen area as the level of interest.

This concludes the explanation of Figure 10.

Using FIG. 11, an example of calculating the interest level for each of the submodels 701 and 702 of the three-dimensional model 700 will be described. The log analysis unit 103 determines that the display area of the submodel 701 (the area of the part of the submodel 701 displayed on the screen 132) is larger than the display area of the submodel 702 relative to the area of the restored screen 132. For this reason, the log analysis unit 103 determines that the interest level of the submodel 710 is larger than that of the submodel 702. The display area of the part of the submodel included in the screen 132 may be the number of pixels of that part. Which pixel is which pixel of which submodel can be specified by a drawing algorithm of the three-dimensional model, such as a rasterization method or a ray tracing method. As described above, an example of a method of calculating the interest level is the ratio of the submodel display area to the area of the screen 132. That is, this is an example of (A) of the above-mentioned (A) and (B). The interest level may be calculated based on (B) in addition to or instead of (A). For example, the log analysis unit 103 may identify the display time length of the screen 132 and the display time length of the sub-model on the screen 132, and calculate the ratio of the display time length of the sub-model on the screen 132 to the display time length of the screen 132. This concludes the explanation of FIG. 11.

The administrator providing unit 104 collects information on user interests (interest subjects and their degree of interest) recorded in the analysis result storage 123, and performs aggregation or statistical processing of the user interests of multiple users. The administrator providing unit 104 provides administrator-oriented data, which is the result of the aggregation or statistical processing, to the administrator terminal 112 of the administrator 111. For example, the administrator providing unit 104 rearranges the display order of interest subjects based on the degree of interest of multiple users (or one user designated by the administrator 111), or displays information on some submodels that meet the conditions designated by the administrator 111. For example, it is possible to display the transition of submodels that are of high interest to users, or information in which submodels are rearranged in order of high interest to users for each model. Furthermore, it is possible to display which date and time data for each submodel was of high interest. In this embodiment, the display to the administrator is shown as an example, but this display may also be applied to the display to the user. This concludes the explanation of FIG. 3.

An example of the display of the administrator terminal 112 will be described with reference to FIG. 4. FIG. 4 shows a screen 301 displayed on the administrator terminal 112 based on administrator-oriented data. This display example shows that, for a three-dimensional model of the ABC Building, of the sub-models of the shuttle elevator, low-rise elevator, and high-rise elevator contained in the three-dimensional model of the ABC Building, the shuttle elevator has the highest degree of interest, followed by the low-rise elevator and then the high-rise elevator. The interest levels here are expressed as the average, median, 90th percentile, etc.

For each submodel, the interest level may be the ratio of the time length for which the submodel is displayed to the time length for which the three-dimensional model is displayed on the screen 132 of the user terminal 102. In the screen 301, graphs 302, 303, and 315 respectively show which time (time period) the user is interested in in the state of the submodel over time. The vertical axes 311, 313, and 315 of each graph are axes (examples of the first axis) corresponding to the level of interest (and elevator waiting time), and the horizontal axes 312, 314, and 316 are axes corresponding to time (examples of the second axis perpendicular to the first axis). The solid lines 321, 323, and 325 of the graph respectively show the time series of the interest level (which time (time period) the user is interested in), and the dashed lines 322, 324, and 326 respectively show the time series of elevator waiting time. The interest level value for each time period here may be the average interest level calculated for that time period based on the simulation data and the operation log data, but it is considered preferable to use the total calculated interest level. If the average interest level is used, the number of times the content is displayed is not taken into account. The "time period" referred to here may be a unit of time such as one minute or one hour. Furthermore, the waiting time for each time period here may be the total waiting time for all floors of the building or the average waiting time. Furthermore, the waiting time for each time period may be calculated and displayed by floor. "Waiting time" is an example of an index (index value).

In graphs 302 and 303, the peak positions of interest level and waiting time are roughly the same. Therefore, the times (time periods) when elevator waiting times are long coincide with the times (time periods) when users' interest levels are high. In contrast, in graph 304, it can be seen that users' interest levels are high even at times when elevator waiting times are not at their peak. For example, it can be seen that users' interest levels are high due to other indicators other than waiting time. In this way, the administrator can easily understand the relationship between waiting time and interest level. Other types of elevator-related indicators (for example, the number of people waiting at the landing, the number of passengers in the car) may be used instead of or in addition to waiting time. This concludes the explanation of Figure 4.

The explanation of FIG. 4 can be summarized, for example, as follows. The multiple sub-models may include two or more sub-models each corresponding to two or more elevators. The simulation data may include data representing values for each time period for each elevator-related indicator (e.g., waiting time, number of people waiting at the landing, number of passengers) for each of the two or more elevators. The log analysis unit 103 may calculate the interest level for each time period for each of the two or more elevators based on (A) above, and identify the index value for each time period from the simulation data. The data for the administrator may represent a time series of the identified index value and the calculated interest level for each of the two or more elevators.

Another example of the display of the administrator terminal 112 will be described with reference to FIG. 5. In this example, sub-models are displayed in descending order of interest level for each user (e.g., a user designated by the administrator). This allows the administrator to grasp the points in which each user is interested. Specifically, for example, the administrator providing unit 104 tabulates or performs statistical processing of the user interests (interest subjects and interest levels) of each user, generates administrator-oriented data representing the results of the tabulation or statistical processing, and provides the administrator-oriented data to the administrator terminal 112. A screen 401 is displayed on the administrator terminal 112 based on the administrator-oriented data. This concludes the description of FIG. 5.
Effects of the embodiment

The administrator 111 can easily identify the subjects (sub-models) that multiple users (or a single user) are interested in and the level of interest, making it easier to implement elevator operation improvement proposals that are in line with the interests of users. For example, for the lobby floor of an elevator that travels from the entrance of a building to each floor, the waiting time can be calculated by measuring the elevator boarding time and the queuing start time for each person independently and assuming that people board in order of arrival. Since the waiting time can be calculated without tracking people for long periods of time even during peak hours, the system configuration can be simplified and improved accuracy is expected.

Although one embodiment of the present invention has been described above, this is merely an example for the purpose of explaining the present invention, and is not intended to limit the scope of the present invention to this embodiment. The present invention can be implemented in various other forms.
