Description

Building information visualization device

Technical Field

The present invention relates to a building information visualization device for visualizing building utilization information.

Background

Patent document 1 discloses the following technique: the operation of the elevator is simulated according to the application of the building, the number of floors, the person, the speed, the number of the stations, the building specification and the like, and the specification of the elevator equipment required by the building of the building is answered according to the operation simulation result.

As a result of the operation simulation of patent document 1, the usage state of each floor of the building is useful not only when the building is newly designed but also when an existing building is modified (for example, a tenant is replaced, and the installation floor of a smoking place, a dining room, or the like is changed). In addition, in such an intention determination, various numerical information accumulated for each floor, such as the entrance/exit status, the usage status of equipment (e.g., air conditioners and lighting), and the power consumption status, is required in addition to the operation status of the elevator.

However, it is difficult to accurately grasp the use state of the building based on the numerical information accumulated as described above. In particular, the following problems are present: the more the number of buildings, the more the number of elevators, and the more the number of tenants living in, the more difficult it is to grasp the usage status of the buildings.

Detailed Description

Embodiments of the present invention will be described below with reference to the drawings. Hereinafter, in this specification, unless otherwise specified, the same reference numerals are given to portions having the same functions, and overlapping descriptions are omitted.

Fig. 1 is a diagram showing a schematic configuration of an elevator 1 according to an embodiment of the present invention. The elevator 1 of the present embodiment mainly includes a car 2, a tail cable 3, and an elevator control device 10. The mechanical structure of the elevator 1 is the same as that of the conventional one, and therefore, detailed description thereof is omitted.

The car 2 has an internal space into which a user enters, and is provided with a car door 4 for allowing the user to enter and exit the internal space. The car 2 is connected to a counterweight (not shown) via a main rope (not shown) in a lifting path 5 extending in the vertical direction in the building. Further, the main rope is wound up or paid out by a winding machine (not shown), and thereby the car 2 travels in the vertical direction in the ascending/descending path 5.

The elevator control device 10 is installed in, for example, a machine room 6 provided in an upper part of the elevator shaft 5. The elevator control device 10 is connected to the car 2 via a tail cable 3. The elevator control device 10 transmits a control signal for operating the car 2 via the tail cable 3, and receives operation information of the car 2 via the tail cable 3.

Landings

7a and 7b are provided on respective floors of a building at positions adjacent to the lifting path 5. The car 2 is stopped at a position facing the

landings

7a, 7b, and the car door 4 is opened, whereby a person at the

landings

7a, 7b can get into the car 2, or a person in the car 2 can get out of the elevator 1.

Operation panels

8a and 8b are provided at the

respective stations

7a and 7 b. The

operation panels

8a and 8b include at least one of an up call key for calling the car 2 moving upward from the floor and a down call key for calling the car 2 moving downward from the floor. More specifically, the operation panel 8a on the lowest floor includes only the up-call key, the operation panel 8b on the uppermost floor includes only the down-call key, and the operation panel on the halfway floor, which is not shown, includes both the up-call key and the down-call key. The elevator control device 10 receives information indicating that the

operation panels

8a and 8b are pressed through a signal line not shown.

Next, the building information visualization system 100 according to the present embodiment will be described with reference to fig. 2. Fig. 2 is a diagram showing a configuration of building information visualization system 100 according to the embodiment of the present invention. The building information visualization system 100 is composed of a customer building 20, a visualization device (building information visualization device) 30, and a customer operation terminal 40, which are connected via

communication networks

13 and 14. The

communication networks

13, 14 may be, for example, the internet, a mobile communication network, a wired LAN, a wireless LAN, a dedicated line, or a combination thereof. Further, the

communication networks

13, 14 may be one communication network (e.g., the internet). The number of the customer buildings 20 and the number of the customer operation terminals 40 connected to the building information visualization system 100 are not limited to one.

The customer building 20 has a plurality of floors (e.g., 15 floors B2-13F). One or more elevators 1 are installed in the customer building 20. In a customer building 20 (building a) shown in fig. 2, 6 elevators 1 are provided (in fig. 2,

elevator control devices

10a, 10b, 10c, 10d, 10e, and 10f for the 6 elevators are shown).

The 6 elevators 1 operating in the customer building (building a)20 belong to either a high-rise elevator group (bank) a or a low-rise elevator group B. The elevator group a is an elevator group having stopping floors B2, 1F, 8F to 13F. On the other hand, the elevator group B is an elevator group with the range of the stop floor set as B1-7F. The elevator control devices 10a to 10c are connected to an elevator group management device 11, and the elevator control devices 10d to 10f are connected to an elevator group management device 12.

In addition, 3 elevators 1 belonging to elevator group a are operation-controlled by elevator

group management device

11, and 3 elevators 1 belonging to elevator group B are operation-controlled by elevator group management device 12. The elevator

group management devices

11 and 12 collect the operation information (e.g., the number of persons staying at each floor, the elevator waiting time, the number of elevator call registrations, etc.) of the elevator 1 managed by the elevator

group management devices

11 and 12 via the elevator control devices 10a to 10 f.

The number of staying persons is, for example, an integrated value of values obtained by dividing a difference value of detection values of weight sensors (not shown) provided in the elevator 1 by a predetermined average body weight (for example, 50kg) when the elevator 1 stops at the

landings

7a and 7 b. That is, if the detection value of the weight sensor decreases by 200kg during the period from the opening to the closing of the

car door

4, 4 persons come out from the elevator 1 (the number of persons staying at the floor increases by 4 persons). On the other hand, if the detected value of the weight sensor increases by 150kg during the period from the opening to the closing of the

car door

4, 3 persons get into the elevator 1 (the number of persons staying at the floor is reduced by 3 persons).

The elevator waiting time is a time from when the up call key or the down call key of the

operation panels

8a, 8b is pressed until the elevator 1 reaches the

corresponding landing

7a, 7 b. The elevator waiting time is, for example, the difference between the time at which the

operation panels

8a, 8b are operated and the time at which the elevator 1 stops at the

corresponding landings

7a, 7 b. The number of times of elevator call registration is the number of times the up call key and the down call key of the

operation panels

8a and 8b are pressed. In addition, the elevator waiting time and the number of times of elevator call registration of the midway floor may be accumulated separately for the case where the up call key is pressed and the case where the call key is pressed.

For example, the elevator control devices 10a to 10f collect information (for example, a difference value between detection values of the weight sensors, a time when the

operation panels

8a and 8b are operated, a time when the elevator 1 is stopped, and the like) for calculating the operation information from the corresponding elevator 1 every 1 second. The elevator control devices 10a to 10f calculate the integrated value of the number of staying persons per 15 minutes, the average value of the elevator waiting time, and the integrated value of the number of elevator call registration times based on the collected information, and transmit the calculated results to the elevator

group management devices

11 and 12.

The elevator

group management devices

11 and 12 store the operation information every 15 minutes acquired from the elevator control devices 10a to 10f in a storage device (not shown). The elevator

group management devices

11 and 12 add a building ID, an elevator group ID, an elevator ID, date and time information, and a floor name to the travel information collected during a predetermined period (for example, 1 day), and transmit the information to the visualization device 30 through the communication network 13.

The building ID is a building identifier for identifying the building in which the elevator 1 serving as the collection source of the operation information is installed. The elevator group ID is an elevator group identifier for identifying an elevator group to which the elevator 1 as a collection source of the operation information belongs. The elevator ID is an elevator identifier for identifying the elevator 1 that is the collection source of the operation information. The date and time information indicates a range (start time to end time) of collection dates and times of the operation information. The floor name is a floor identifier for identifying a floor to which the operation information is collected.

The method of accumulating the operation information, the method of collecting the operation information, and the transmission timing are not limited to the above-described examples. As an example, the information collected by the elevator control devices 10a to 10f may be transmitted to the visualization device 30 via the elevator

group management devices

11 and 12 in real time and accumulated by the visualization device 30. As another example, the information stored in the storage devices of the elevator

group management devices

11, 12 may be copied to the maintenance terminal by a maintenance person and then registered to the visualization device 30.

The visualization device 30 mainly includes a storage device 31, an integration processing unit 32, a matrix generation unit 33, and a visualization processing unit 34. The visualization device 30 includes, for example, a CPU (central processing unit), a ROM (read only memory), a RAM (random access memory), and a communication interface. The CPU reads out and executes the program codes stored in the ROM, thereby causing the software and the hardware to cooperate with each other, function as the integration processing unit 32, the matrix generation unit 33, and the visualization processing unit, and execute other various processes. That is, the integration processing unit 32, the matrix generation unit 33, and the visualization processing unit 34 correspond to algorithms executed by the controller.

The storage device 31 is constituted by a ROM, a RAM, or an HDD (hard disk drive). As shown in fig. 3, the storage device 31 stores a user DB31A and a building use information DB 31B. Fig. 3 is a diagram showing a data structure of the user DB31A and the building use information DB 31B.

The user DB31A stores user IDs, passwords, attribute information, and building IDs in association with one another, for example. The user ID and the password are user identifiers for identifying users who can access the visualization device 30. The attribute information is information indicating the attribute of the user, and is a value for setting a "building management company" that manages a plurality of buildings, a "building owner" that owns a building, and the like, for example. The building ID is used to identify the building corresponding to the user. That is, the building IDs "building a" and "building B" corresponding to the attribute information "building management company" identify the buildings managed by the user. Further, the building ID "building C" corresponding to the attribute information "building owner" identifies the building owned by the user.

The building utilization information DB31B stores building IDs, elevator group IDs, elevator IDs, date and time information, floor names, the number of persons staying, elevator waiting times, and the number of elevator call registrations in association with one another, for example. These pieces of information are information obtained from the elevator

group management devices

11 and 12. The building use information DB31B may include, in "other" items, operation information of the elevator (the number of times the car door 4 is opened or closed, the number of times the car door 4 is reversed, the number of times the elevator 1 is started, and the like) acquired from the elevator control devices 10a to 10f, and information indicating an operation status, an entrance/exit status, a usage status of equipment (e.g., air conditioner, lighting), and a power consumption status of the elevator. These pieces of information are collected by a collection device (not shown) provided in the building.

The number of staying persons, the waiting time of the elevator, the number of times of call registration of the elevator, the operation information of other elevators, the operation status of the elevator, the entrance/exit status, the usage status of devices (e.g., air conditioners and lighting), and the power consumption status are examples of the building utilization information of the customer building 20. However, specific examples of the building use information are not limited to these, and all numerical information indicating the use states of floors correspond to the building use information.

The integration processing unit 32 integrates the building use information included in the building use information DB31B in accordance with a specification condition specified by the user. For example, the accumulation processing unit 32 accumulates a plurality of building use information items corresponding to the same floor name for each accumulation period (for example, 1 hour, 1 day, 1 month) specified by the user. As another example, the accumulation processing unit 32 accumulates (for example, accumulates or averages) a plurality of building use information items corresponding to the same elevator group ID. The integration processing unit 32 will be described in detail later with reference to fig. 4.

The matrix generation unit 33 generates

matrix data

3016, 3026, and 3036 shown in fig. 5 to 7, for example. The matrix data is data representing a two-dimensional matrix in which a first axis is a floor and a second axis perpendicular to the first axis is time. The display form of each cell of the two-dimensional matrix at the intersection of a floor and time differs depending on the size of building use information corresponding to the floor name indicating the floor and date and time information indicating the time.

The display form of the cell refers to at least one of the type of color (e.g., blue, green, yellow, red, etc.), the shade of the color, and the pattern (e.g., the line width of the shade, the density of dots, etc.), for example. For example, the building use information may be closer to blue as the value thereof is smaller, and may be closer to red as the value thereof is larger. As another example, the color may be made lighter as the value of the building utilization information is smaller, and the color may be made darker as the value of the building utilization information is larger.

In the present embodiment, when the value of the building utilization information is positive, the dot pattern is added to the corresponding cell, and the density of the dots is decreased as the absolute value is smaller, and is increased as the absolute value is larger. When the value of the building use information is negative, a pattern of shading is added to the corresponding cell, and the line width is made thinner as the absolute value is smaller, and the line width is made thicker as the absolute value is larger. The relationship between the value of the building utilization information and the display format may be changed according to the preference of the user who operates the terminal 40 by the customer.

In the present embodiment, the first axis is a vertical axis, and the second axis is a horizontal axis. The vertical axis is an axis extending in the vertical direction of the letters (numerals). On the other hand, the horizontal axis refers to an axis perpendicular to the vertical axis. However, the method of the first axis and the second axis is not limited to the above example, and the first axis may be a horizontal axis and the second axis may be a vertical axis.

The visualization processing unit 34 performs a process of visualizing the matrix data generated by the matrix generation unit 33. The visualization processing is, for example, processing for displaying matrix data on a display (not shown) of the visualization device 30; a process of causing a printer connected to the visualization device 30 to print out matrix data; and a process of transmitting the matrix data to the customer operation terminal 40 for display on the display of the customer operation terminal 40. The data format of the matrix data is not particularly limited, and may be, for example, an image format, an HTML format, an XML format, a CSV format, or the like.

The customer operation terminal 40 is an information processing terminal held by a customer, and includes a display, an operation device (e.g., a keyboard, a mouse, or a touch panel), and a communication interface. Specific examples of the customer operation terminal 40 are not particularly limited, and a PC, a tablet PC, a smart phone, and the like correspond to the customer operation terminal 40.

Next, referring to fig. 4 and 5, a process between the visualization device 30 and the customer operation terminal 40 will be described. Fig. 4 is a flowchart showing a process executed between the visualization device 30 and the customer operation terminal 40. Fig. 5 is a diagram showing the building information screen 301 including the matrix data 3016.

In the present embodiment, the following description will be made assuming that the visualization device 30 functions as a Web server and a Web browser is installed in the client operation terminal 40. The visualization device 30 and the customer operation terminal 40 may constitute a client & server type system, and a dedicated program may be installed in the customer operation terminal 40.

First, the user operating the terminal 40 by the customer inputs the user ID and the password assigned to the user to a login page (not shown) by an operating device. Then, the customer operation terminal 40 transmits the user ID and the password input by the user to the visualization device 30 through the communication network 14 in order to request login (S11). Here, it is assumed that the user ID "001" and the password "abc" are input.

Based on the reception of the user ID and password from the customer operation terminal 40, the visualization device 30 reads the building IDs "building a" and "building B" corresponding to the user ID and password from the user DB 31A. Then, the visualization device 30 generates a building information screen based on the read building ID (S12), and transmits the generated building information screen to the customer operation terminal 40 via the communication network 14 (S13).

Upon receiving the building information screen from the visualization device 30, the customer operation terminal 40 displays the building information screen on the display (S14). The building information screen displayed here is, for example, a column of "maximum number of people staying at home" in the elevator group selection area 3012, a display method designation area 3013, and a setting content display area 3014 in the building information screen 301 shown in fig. 5, and the matrix data 3016 is in a non-display state.

As shown in fig. 5, the building information screen 301 includes a building utilization information selection area 3011, an elevator group selection area 3012, a display method designation area 3013, a setting content display area 3014, and a "display" button 3015.

The building utilization information selection area 3011 includes a pull-down menu for allowing the user to select the type of building utilization information displayed in the cells of the matrix data. The elevator group selection area 3012 includes check boxes for selecting a building and an elevator group to be visualized, an area for displaying the number of elevators 1 belonging to the corresponding elevator group, and an area for displaying the maximum number of persons staying in the corresponding elevator group. In the elevator group selection area 3012, all elevator groups corresponding to the building ID read out by the visualization device 30 in S12 can be selected.

The display method designation region 3013 includes a unit time designation field and a comparison display field. The unit time designation field includes a radio button for designating a unit of integration (integration period) of the building utilization information and a text box for inputting an integration target period of the building utilization information. The comparison display field includes a check box for comparing and displaying matrix data in different accumulation target periods and a text box for inputting an accumulation target period to be compared. The set content display region 3014 displays the content specified in the unit time specification field of the display method specification region 3013.

The "display" button 3015 is a button for causing the visualization device 30 to generate matrix data and display the generated matrix data on the building information screen 301 in accordance with a specification condition specified by the user via the building use information selection area 3011, the elevator group selection area 3012, and the display method specification area 3013.

As an example, as shown in fig. 5, a case will be described in which "number of staying persons" is selected in the building use information selection area 3011, "building ID" building a "and elevator group ID" elevator group B "are selected in the elevator group selection area 3012," unit time "radio buttons are selected in the unit time designation field of the display method designation area 3013," 6 months and 30 days in 2018 "are input, and the" display "button 3015 is clicked.

Based on the click of the "display" button 3015, the customer operation terminal 40 transmits the specification conditions specified in the building use information selection area 3011, the elevator group selection area 3012, and the display method specification area 3013 to the visualization device 30 via the communication network 14 in order to request the transmission of matrix data (S16).

The accumulation processing unit 32 of the visualization device 30 accumulates the building use information registered in the building use information DB31B based on the reception of the specified condition from the customer operation terminal 40 (S17). More specifically, the accumulation processing unit 32 reads all records corresponding to the building ID "building a", the elevator group ID "elevator group B", and the date and time information "6/30/2018" as the accumulation target period from the building utilization information DB 31B. Next, the accumulation processing unit 32 accumulates (accumulates) the number of remaining persons in the read record in units of 1 hour. That is, the number of staying people in 2018 for 6, 30 days was counted at 0 to 1, 1 to 2, … …, and 23 to 24 points per one counting cycle.

Next, the matrix generation unit 33 of the visualization device 30 generates the matrix data 3016 using the specified conditions received from the customer operation terminal 40 and the building use information accumulated by the accumulation processing unit 32 (S18). More specifically, the matrix generation unit 33 generates a two-dimensional matrix including the vertical axis of 8 cells corresponding to the stop floors (B1 to 7F) of the elevator group B in the building a and the horizontal axis of 24 cells obtained by dividing the integration target period into the integration periods. Then, the matrix generation unit 33 determines the display format of each cell at the intersection of the stop floor and the integration period based on the number of remaining persons integrated by the integration processing unit 32.

That is, as shown in fig. 5, the matrix generation unit 33 adds a shade in which the line width becomes smaller as the absolute value is smaller and a shade in which the line width becomes thicker as the absolute value is larger to each cell of the stop floor "1F" in which the number of stopped persons is negative. The matrix generation unit 33 adds a point having a lower density as the absolute value is smaller and a point having a higher density as the absolute value is larger to each cell of the stop floors where the number of stopped persons is positive. Then, the matrix generation unit 33 whites out each cell in which the number of remaining persons is 0.

Further, the controller of the visualization device 30 determines the integration period 3017 in which the number of people staying in the building is the largest, based on the matrix data 3016 generated by the matrix generation unit 33. Then, the controller calculates the maximum number of staying persons by summing up only positive values of the number of staying persons at each floor in the determined accumulation period 3017. Then, the visualization processing unit 34 of the visualization device 30 transmits the matrix data 3016 generated by the matrix generation unit 33 and the maximum number of remaining persons calculated by the controller to the client operation terminal 40 via the communication network 14 (S19).

Next, the customer operation terminal 40 displays the matrix data 3016 received from the visualization device 30 on the building information screen 301 (S20). In addition, the customer operation terminal 40 displays the received maximum number of staying persons in the column of "maximum number of staying persons (persons)" in the elevator group selection area 3012. Further, as shown in fig. 5, the visualization device 30 may calculate not only the maximum number of remaining persons of the elevator group for which the check box is clicked but also the maximum number of remaining persons of all elevator groups displayed in the elevator group selection area 3012 and display the calculated maximum number of remaining persons in the building information screen 301.

According to the above embodiment, for example, the following operational effects are produced.

As in the above-described embodiment, by differentiating the display form of each cell of the matrix of floors and time according to the size of the corresponding building utilization information, it is possible to intuitively grasp, for example, the distribution of the building utilization information of each floor at the same time, the temporal change of the building utilization information of the same floor, and the like at a glance. As a result, when an existing building is modified, the current building usage can be easily and accurately identified. In particular, by arranging floors vertically, it is possible to superimpose the actual building image on the matrix data, and thus it is possible to grasp the building usage more intuitively.

Further, according to the above-described embodiment, the user can specify the cumulative period of building use information (for example, 1 hour, 1 day, 1 month, and the like) by the unit time specification field of the display method specification region 3013. Thus, the use state of the building can be analyzed from various angles from the short-term flow of people in the building to the long-term flow of people. Further, by integrating and displaying building use information of a plurality of elevators 1 belonging to the same elevator group, the flow of people in the building can be grasped more intuitively. However, the matrix data may be generated for each elevator 1 without accumulating building utilization information for each elevator group.

In addition, in the above-described embodiment, in the case where the user who requests visualization is a building owner, the elevator group selection area 3012 can only select a building and an elevator group owned by the user. On the other hand, in the case where the user who requests visualization is a building management company, the elevator group selection area 3012 can only select a building managed by the user and an elevator group of the building. That is, the visualization device 30 is configured to visualize only the building utilization information of the building ID and the elevator group ID corresponding to the user ID of the user operating the customer operation terminal 40. In this way, information that can be visualized can be divided according to the user ID (in other words, the attribute of the user), and information useful for each user can be presented.

In the above-described embodiment, the example has been described in which the visualization device 30 collects the building use information collected by the elevator

group management devices

11 and 12 in a batch manner, and displays the matrix data 3016 indicating the past building use information on the customer operation terminal 40. However, the visualization device 30 may collect building use information from the elevator control devices 10a to 10f in real time and visualize matrix data indicating the current building use information. In this case, the building information screen 301 may automatically update the matrix data 3016 at predetermined intervals, as in the case of moving image reproduction.

(modification example)

Next, a modified example of the above embodiment will be described. Note that description of common points with the above embodiments is omitted, and description of different points will be mainly given.

Fig. 6 is a display example of matrix data 3026 when both check boxes corresponding to the building ID "building a" and the elevator group ID "elevator group a" and check boxes corresponding to the building ID "building a" and the elevator group ID "elevator group B" are clicked in the elevator group selection area 3022.

First, in S17, the difference from the process of fig. 5 is that in addition to reading the record containing the building ID "building a" and the elevator group ID "elevator group B", the record containing the building ID "building a" and the elevator group ID "elevator group a" is also read. In S18, the difference from the processing of fig. 5 is that a two-dimensional matrix is generated which is composed of the vertical axis of 15 cells corresponding to the stop floors (B2 to 13F) of the elevator group A, B of building a and the horizontal axis of 24 cells obtained by dividing the integration target period into integration periods. The other processing is the same as in the case of fig. 5.

As a result, matrix data 3026 shown in fig. 6 is generated and displayed on the display of the customer operation terminal 40. The matrix data 3026 differs from the matrix data 3016 shown in fig. 5 in that the stopping floors (B2, 1F, 8F to 13F) shown by elevator group a (first elevator group identifier) and the stopping floors (B1 to 7F) shown by elevator group B (second elevator group identifier) are combined on the vertical axis.

The building information screen 302 shown in fig. 6 allows the flow of people in the entire building a to be intuitively understood at a glance. For example, if referring to fig. 6, it can be intuitively understood at a glance that the time zone 3027 in which the number of users of elevator 1 belonging to elevator group a is the largest is different from the time zone 3028 in which the number of users of elevator 1 belonging to elevator group B is the largest.

Fig. 7 shows an example of display of the

matrix data

3036 and 3037 when the check box of the comparison display field is clicked in the display method designation field 3033 and the comparison target accumulation period "2015, 6, month, and 30 days" is input.

First, fig. 17 is different from the processing of fig. 5 in that a record having date and time information corresponding to a comparison target accumulation target period "2015 year 6 month 30 day" is read in addition to a record having date and time information corresponding to an accumulation target period "2018 year 6 month 30 day". In S18, the difference from the processing of fig. 5 is that matrix data 3036 corresponding to the accumulation target period "6/30/2018" is generated, and matrix data 3037 corresponding to the accumulation target period "2015/6/30/2015" as a comparison target is also generated. The other processing is the same as in the case of fig. 5.

As a result, the

matrix data

3036 and 3037 shown in fig. 7 are generated and displayed side by side on the display of the customer operation terminal 40. The setting

content display regions

3034A and 3034B are displayed in correspondence with the

matrix data

3036 and 3037, respectively. According to the building information screen 303 shown in fig. 7, it is possible to intuitively grasp at a glance the change in the flow of people in the building a between the past (

day

6 and 30 in 2015) and the present (

day

30 and 6 in 2018) (for example, the change in the time zone in which the number of staying people is the largest, the increase or decrease in the maximum number of staying people per floor, and the like).

In the example of fig. 7, the

matrix data

3036 and 3037 are generated for each of a plurality of ranges of collection dates and times (accumulation target periods) designated by the user, but the method of selecting matrix data to be displayed side by side is not limited to this.

As an example, the user may specify one accumulation target period and a plurality of buildings by the customer operation terminal 40. Further, the visualization device 30 may accumulate the building use information in the accumulation target period for each of the plurality of buildings specified by the user to generate the matrix data. This makes it possible to compare the use states of different buildings in the same period. As other examples, the matrix data of each elevator group of one building may be displayed side by side, or the matrix data of more than 2 buildings may be displayed side by side. Such comparison of matrix data from various viewpoints can be used flexibly in the study of a method for improving the profit or value of real estate and improving the satisfaction of users.

The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the scope of the main content of the invention described in the claims. For example, the above-described embodiments and the following modified examples may be combined in any combination without departing from the scope of the main subject matter of the present invention.
