Elevator control System 100

Fig. 2 is a block diagram of an elevator control system 100 according to an embodiment. The elevator control system 100 shown in the figure is a system for group management control of a plurality of elevators, and includes a visualization device 30 for visualizing an elevator operation state. The elevator control system 100 is composed of a building management device 20, a visualization device 30 for elevator operation states, and a terminal device 40, which are connected via communication networks 13 and 14. These components are configured as follows.

< communication networks 13, 14 >

The communication networks 13 and 14 may be, for example, the internet, a mobile communication network, a wired LAN, a wireless LAN, a dedicated line, or a combination thereof. In addition, the communication networks 13, 14 may be one communication network (e.g., the internet). The building management apparatus 20 and the terminal apparatus 40 connected to the visualization apparatus 30 via the communication networks 13 and 14 are not limited to one, and may be plural. In addition, the building management apparatus 20 and the terminal apparatus 40 do not need to include 1: 1 corresponds to each other.

< mansion management apparatus 20 >

The building management apparatus 20 includes a part for managing the operation of a plurality of elevators installed in the customer buildings, and is installed in each customer building, for example. Each building management apparatus 20 includes a plurality of elevator control apparatuses 10 provided in the elevators of the customer buildings. Each building management apparatus 20 includes a group management apparatus 21 that manages a plurality of elevator control apparatuses 10 in groups for each group (bank).

As an example, a case is assumed where 6 elevators are installed in a 15-story customer building having an underground floor 2B 2 to an above-ground floor 13F, and the 6 elevators are divided into a combination a for an upper story and a combination B for a lower story for each destination floor. For example, an elevator belonging to the combination a for the upper floors has each of the

floors 2B

2, 1 floor 1F, 8 floors 8F to 13 floors 13F as a stop floor. In the elevator belonging to the combination B for the lower floors, each of the floors 1 floor B1 and 1 floor 1F to 7 floor 7F is defined as a stop floor.

In the building management apparatus 20a of the customer building, the elevator control apparatuses 10a, 10B, and 10c of the elevators belonging to the group a are connected to one group management apparatus 21a, and the elevator control apparatuses 10d, 10e, and 10f of the elevators belonging to the group B are connected to the other group management apparatus 21B.

Similarly, the building management apparatuses 20b of other customer buildings are also connected to the combination management apparatuses 21 in combination groups by the plurality of elevator control apparatuses 10. The elevator control device 10 and the combination management device 21 connected in this manner have the following configurations.

[ Elevator control device 10]

The elevator control device 10 is provided in each elevator as described above, and controls the operation of each elevator by an instruction from the combination management device 21 connected to each elevator. The elevator control device 10 receives operation information from the components of the elevator, and transmits the received operation information to the combination management device 21.

The operation information of the elevator received by the elevator control device 10 is information on (a) the number of passengers on the elevator, (b) the average waiting time, (c) the number of hall call registrations, (d) the number of car call registrations, (e) the elevator riding time, (f) the number of full passage times, and others on each floor. This information is described below with reference to fig. 1.

- (a) number of people taking the elevator-

The number of persons riding the elevator is an integrated value of a value obtained by dividing a difference value of detection values of weight sensors (not shown) provided in the elevator 1 by a predetermined average weight (for example, 50kg) when the car 2 stops at each

landing

7a, 7 b. That is, if the detected value of the weight sensor decreases by 200kg while the car door 4 is opened and closed, 4 persons (4 persons subtracted from the number of persons riding the elevator) are moved down from the car 2. On the other hand, if the detected value of the weight sensor increases by 150kg while the car door 4 is opened to be closed, 3 persons get on the car 2 (the number of persons getting on the car increases by 3 persons). The number of passengers is collected as an integrated value of the period during which the operation information is transmitted to the combination management device 21.

- (b) average waiting time-

The average waiting time is an elapsed time from when the up call button or the down call button of the

landing operation panels

8a and 8b is pressed until the car 2 arrives at the

corresponding landing

7a or 7b, and is an average waiting time in the case where the up call button or the down call button is pressed 1 time. The average waiting time is, for example, a difference between a time at which the

landing operation panels

8a and 8b are operated and a time at which the car 2 stops at the

corresponding landings

7a and 7 b. The waiting time of the intermediate floor may be set to be a sum of the case where the upper call button is pressed and the case where the lower call button is pressed.

- (c) number of landing call registrations-

The number of hall call registrations is the number of times the up call button and the down call button of the

hall operation panels

8a and 8b are pressed, and is, for example, an integrated value of the period during which the operation information is transmitted to the combination management device 21. The number of hall call registrations of the intermediate floor may be a sum of the case where the upper call button is pressed and the case where the lower call button is pressed.

- (d) number of car call registrations-

The car call registration count is the number of times the destination floor registration button of the operation panel 2a located in the car 2 is pressed, and is, for example, an integrated value of the period during which the operation information is transmitted to the combination management device 21.

- (e) time to take the elevator-

The boarding time is, for example, an average value of time required when the landing 7a enters the car 2 and moves to the landing 7 b. The boarding time is, for example, a time from when the passenger rides in the landing 7a and presses a destination floor button (a button of a floor of the landing 7 b) on the inner side of the car 2, and the car door 4 is opened when the car 2 moves to the landing 7 b.

- (f) number of full man passes-

The number of times of passage of a full passenger is, for example, the number of times of passage of the car 2 carrying the full passenger H without stopping at the

corresponding landing

7a, 7b when the up call button or the down call button of the

landing operation panel

8a, 8b is pressed. The full passage count is, for example, a total value of the periods during which the operation information is transmitted to the combination management device 21.

-other-

As another example of the elevator operation information received by the elevator control device 10, the number of times the car door 4 is opened and closed, the number of times the car door 4 is reversed, or the number of times the car door is started, etc. are exemplified. These pieces of operation information are collected by a collection device (not shown) provided in the elevator 1 and transmitted to each elevator control device 10.

[ combination management device 21]

Returning to fig. 2, the combination management device 21 collects (receives) and stores the operation information of the elevator managed by itself per predetermined time from each elevator control device 10. The predetermined time is a predetermined time, and is set to any time of, for example, 5 minutes, 10 minutes, or 15 minutes. The combination management device 21 adds the corresponding building ID, combination ID, elevator ID, date and time information, and floor name to the operation information collected every predetermined time period (for example, 1 day) and transmits the result to the visualization device 30 via the communication network 13.

The method of collecting the operation information by the combination management device 21 and the timing of transmitting the operation information to the visualization device 30 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 in real time by the combination management device 21 and may be collected by the visualization device 30. As another example, the information collected by the combination management device 21 may be copied to a maintenance terminal by a maintenance person and registered in the visualization device 30.

< visualization device 30 >

The visualization device 30 is a device that visualizes the operation state of the elevator managed by each combination management device 21 based on the information transmitted from each combination management device 21. The visualization device 30 is mainly provided with a storage device 31, a collection processing unit 32, an operation state analysis processing unit 33, a visualization processing unit 34, and an availability specification data transmitting unit 35. Such a 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, and may further include a HDD (Hard Disk Drive).

The visualization device 30 as described above is configured such that the CPU reads and executes the program codes stored in the ROM, and the software and hardware cooperate with each other to function as the collection processing unit 32, the operation state analysis processing unit 33, the visualization processing unit 34, and the usability specification data transmitting unit 35. That is, the collection processing unit 32, the operation state analysis processing unit 33, the visualization processing unit 34, and the usability specification data transmitting unit 35 correspond to algorithms executed by the controller. The following describes the functions of the respective units included in the visualization device 30 in detail.

[ storage device 31]

The storage device 31 is composed of a ROM, a RAM, or an HDD, and stores a database in which information necessary for visualizing the operation state of each elevator is organized. The Databases (DB) stored in the storage device 31 are the user database (user DB31a), the analysis condition database (analysis condition DB31b), the improvement method database (improvement method DB31c), the operation information database (operation information DB31d), and the analysis result database (analysis result DB31e) shown in fig. 3 to 7.

Hereinafter, the data structure of each database will be described with reference to fig. 2. Note that, although the databases register data corresponding to each record, common data are collectively shown in one group for the sake of explanation in fig. 3 to 7 for explaining these databases.

User DB31 a-

Fig. 3 is a diagram showing an example of the data structure of the user DB31a stored in the storage device 31. The user DB31a is a database composed of information registered in advance by a system administrator. As shown in the drawing, the user DB31a stores, for example, (1) a user ID, (2) a password, (3) attribute information, and (4) a building ID in association with each other. These pieces of information are as follows.

(1) The user ID and (2) the password are user identifiers for identifying users who can access the visualization device 30. (3) The attribute information is information indicating the attribute of the user, and is set, for example, "building management company" that manages a plurality of buildings, or "building owner" that owns a building. (4) The building ID is a building identifier for identifying a building in which the elevator managed by each combination management apparatus is installed.

That is, the building ID "building a" and the building B "of (4) corresponding to the attribute information" building management company "of (3) identify the building managed by the user of the user ID" 001 "of (1). Further, (4) the building ID "building C" corresponding to (3) the attribute information "building owner" identifies (1) the building that the user ID "002" has.

Analysis conditions DB31 b-

Fig. 4 is a diagram showing an example of the data structure of analysis condition DB31b stored in storage device 31. The analysis condition DB is a database composed of information registered in advance by a system administrator, and an analysis condition for analyzing the operation state of the elevator from the operation information of the elevator is registered. As shown in the figure, the analysis condition DB31b stores (5) the cause of deterioration, (6) the evaluation level, (7) the evaluation item, (8) the evaluation threshold, and (9) the estimation factor in association with each other. This information is as follows.

(5) The deterioration factor is a factor that deteriorates the operation state of the elevator described later, and is any one of the operation information of the elevator described above or an item calculated based on the operation information of the elevator. Such deterioration causes are, for example, "average waiting time" and "full passage occurrence rate". Here, the "average waiting time" is one of the pieces of operation information described earlier. The "percentage of occurrence of full passage" is a value obtained by dividing (e) the number of occurrences of full passage by (c) the number of times of hall call registration in the aforementioned travel information, and is a percentage of full passage of the car when hall call registration is performed.

(6) The evaluation level is information for classifying evaluation items for evaluating the operation state of the elevator, which will be described later, in accordance with the evaluation level, and is information assigned to each evaluation item. That is, as described below, the evaluation items are classified into a cause item for directly evaluating the satisfaction degree of the operating state of the elevator and a factor item for indirectly evaluating the satisfaction degree of the operating state of the elevator by influencing the numerical value of the cause item. The cause item is also (5) a cause of deterioration. In addition, the factor item is a factor causing deterioration. In addition, the same evaluation item may be given an evaluation level of 1 and an evaluation level of 2.

(7) The evaluation items are items for evaluating the operating state of the elevator, and are classified into the cause item corresponding to the evaluation level 1 and the factor item corresponding to the evaluation level 2 as described above. These evaluation items are items selected from the operation information of the elevator described above or items calculated based on the operation information of the elevator. These evaluation items are registered in the analysis condition DB31b in association with the above-described deterioration factor, and a plurality of evaluation items registered in association with the same deterioration factor are collectively managed as one evaluation group.

The cause items (evaluation items of the evaluation level 1) among the evaluation items as described above match the cause of deterioration, and one cause item corresponds to the cause of deterioration. Further, the factor item (evaluation item of evaluation level 2) may correspond to any one of the deterioration causes, and one factor item may correspond to a plurality of deterioration causes. For example, as the factor items (evaluation items of the evaluation level 2), "hall call registration ratio", "car call registration ratio", and "average car door opening duration" are assigned to the deterioration factor "average waiting time".

Here, the "hall call registration ratio" and the "car call registration ratio" are ratios of the respective registration times to the total number of times of the "hall call registration times" and the "car call registration times". The "average car door opening duration" is an average of durations in the case where the car door is opened 1 time. These are values calculated from the operational information described earlier.

(8) The evaluation threshold is a threshold set as a value of the evaluation item, and the value of the evaluation item is a value that determines that the evaluation item has a problem when the evaluation threshold is exceeded. For example, if the evaluation item is "average waiting time", a threshold value of "average waiting time" until the arrival of the car in the 1 hall call registration is set to 50 seconds, and if the "average waiting time" exceeds 50 seconds, it is determined that there is a problem.

(9) The estimated factor is a factor that estimates deterioration when a factor item given an evaluation level 2 among the evaluation items deteriorates beyond an evaluation threshold. The estimation factor is set only in the factor item (evaluation item of evaluation level 2). For example, as an estimation factor in the case where the hall call registration ratio exceeds the evaluation threshold (80%), there is registered "the number of times of stopping of the car due to the hall call per unit time is large".

Improvement method DB31 c-

Fig. 5 is a diagram showing an example of a data structure of the improvement method DB31c stored in the storage device 31. The improvement method DB31c is a database composed of information registered in advance by a system administrator, and is registered with an improvement method for each deterioration cause that deteriorates the running state of the elevator. As shown in the figure, the improvement method DB31c stores (5) the cause of deterioration, (7) the evaluation item, (9) the estimation factor, (10) the improvement classification, and (11) the improvement method in association with each other. The causes of deterioration (5), evaluation items (7), and estimation factors (9) are as described above. However, the evaluation item (7) corresponds only to a factor item (evaluation item of evaluation level 2) for indirectly evaluating the satisfaction degree of the operation state of the elevator. The methods of (10) improving the discrimination and (11) improving the discrimination are as follows.

(10) The improvement classification is information for classifying the improvement methods when the evaluation items of each deterioration cause deteriorate into improvement on the system and improvement based on the operation of the elevator, and is information assigned to the (11) improvement method described below. That is, the improvement method in the case where the evaluation item is deteriorated is classified into an improvement in a system by elevator control and an improvement in operation related to a method of using an elevator.

The improvement in the system is, among other things, an improvement method in connection with the control of the elevators, corresponding to an improvement by adjusting the so-called availability use. Further, the improvement in operation corresponds to improvement in enlightening activities regarding the use of elevators targeted for tenants, offices, or users carried into the customer premises.

(11) The improvement method is a method for improving each of the presumptive factors, and one or more methods correspond to each of the presumptive factors and each of the improvement divisions. For example, when the estimated factor is "the number of stops due to hall calls per unit time is large", a method of adjusting the congestion degree threshold value to reduce the number of hall calls stops "is used as a method of improving the system, that is, as an adjustment method for usability. As an improvement method in operation, a method of "driving a ladder to a fixed number (increasing the ladder driving rate)" is used.

Operation information DB31d

Fig. 6 is a diagram showing an example of the data structure of the operation information DB31d stored in the storage device 31. The operation information DB31d is a database constituted by information transmitted from the combination management device 21 every predetermined period (for example, 1 day). As shown in the figure, the travel information DB31d stores, for example, (4) a building ID, (21) a combination ID, (22) an elevator ID, (23) date and time information, (24) a floor name, and (25) travel information in association with each other. The operation information DB31d stores the combination ID (21) and the date and time information (23) in association with each other.

The building ID (4) is a building identifier for identifying the building in which the elevator managed by the combination management device 21 is installed, as described in the user DB31a (see fig. 3). (21) The combination ID is a combination identifier that identifies a combination to which the elevator managed by the combination management device 21 belongs. (22) The elevator ID is an elevator identifier for identifying an elevator managed by the combination management device 21. (23) The date and time information is information indicating a range (start time to end time) of a predetermined time for collecting the operation information. (24) The floor name is a floor identifier that identifies a floor to which an elevator managed by the combination management device 21 arrives.

(25) The operation information is the operation information transmitted from the elevator control device 10 to the combination management device 21 as described above, and includes (a) the number of passengers, (b) the average waiting time, (c) the number of hall call registrations, (d) the number of car call registrations, (e) the number of full-man passage occurrences, and others.

The (25) operation information of the operation information DB31d is not limited to the information transmitted from the elevator components to the elevator control device 10, and may be information created by a simulation device that simulates the operation of an elevator, for example. Such operation information is inputted to the visualization device 30 from an external terminal device, for example, and stored in the operation information DB31d of the storage device 31.

The (25) operation information of the operation information DB31d may include other information that affects the operation state of the elevator, in addition to the information transmitted from each elevator control device 10 to the combination management device 21. The other information is building use information, and is all numerical information indicating the use status of each floor of a building in which an elevator is installed, for example. Such building use information may be received from a collection device (not shown) installed in the customer building via each elevator control device 10 or directly from the corresponding combination management device 21, and transmitted as (25) operation information to the storage device 31 of the visualization device 30.

Analysis results DB31 e-

Fig. 7 is a diagram showing an example of the data structure of the analysis result DB31e stored in the storage device 31. The analysis result DB is a database composed of information registered when the deterioration of the operation state is detected in the analysis processing in the operation state analysis processing unit 33 described below. As shown in the figure, the analysis result DB stores, for example, (4) a building ID, (21) a combination ID, (23) date and time information, (31) a deterioration detection date and time, (5) a cause of deterioration, and (7) evaluation items in association with each other.

The information of the operation information DB31d described above is registered based on the result of the analysis processing performed by the operation state analysis processing unit 33 based on the information of the analysis condition DB31 b. The procedure of the analysis processing performed by the operation state analysis processing unit 33 will be described in detail in the following analysis method of the elevator operation state.

[ collective processing unit 32]

Next, the summary processing unit 32 shown in fig. 2 is a part that summarizes (25) the operation information (see fig. 6) of the summary operation information DB31d according to a predetermined condition set in advance by the system administrator so as to be easily used for detection of deterioration of the operation state by the operation state analysis processing unit 33 described below. For example, the aggregation processing unit 32 aggregates (e.g., integrates, averages) the plurality of pieces of building use information corresponding to the same combination ID for aggregation periods (e.g., 5 minutes, 15 minutes, 30 minutes) designated by the system manager. Therefore, the (8) evaluation threshold of the analysis condition DB31b is registered in units that can correspond to each aggregation period specified by the system manager (see fig. 4). The summary cycle is also a cycle in which the predetermined time for which the combination management device 21 collects the operation information is the minimum unit.

The collection processing unit 32 collects information necessary for visualizing the analysis result in the operation state analysis processing unit 33 described below in the visualization processing unit 34 described below from each database.

Then, the summary processing unit 32 acquires, from the improvement method DB31c, an improvement method corresponding to the cause of deterioration identified and registered in the analysis result DB31e in the operation state analysis processing unit 33. The procedure of the visualization processing performed by the collective processing unit 32 will be described in detail below in the following method of analyzing the elevator operation state.

[ operating condition analysis processing unit 33]

The operation state analysis processing unit 33 performs analysis processing of the operation information of the elevator registered in the operation information DB31d based on the information of the analysis condition DB31b, and detects deterioration of the operation state of the elevator. The operation information analysis processing by the operation state analysis processing unit 33 is performed for each of the date and time information and the floor. When the operation information (see fig. 6) of the operation information DB31d is collected by the collection processing unit 32, deterioration of the operation state is detected based on the collected operation information.

When the deterioration is detected, the operation state analysis processing unit 33 specifies the cause of deterioration and the evaluation items causing the deterioration, and registers (4) the building ID, (21) the combination ID, (23) the date and time information, (31) the deterioration detection date and time, (5) the cause of deterioration, and (7) the evaluation items in the analysis result DB31e in association with each other (see fig. 7). Further, the operating state analysis processing unit 33 specifies (9) the estimation factor registered in the improvement method DB31c by specifying (7) the evaluation item. The detection of the deterioration of the operating state by the operating state analyzing and processing unit 33 will be described later in a visualization method of the operating state of the elevator and an elevator control method.

[ visualization processing unit 34]

The visualization processing unit 34 performs processing for visualizing the operation state of the elevator based on the analysis processing of the operation state analysis processing unit 33. The terminal device 40 described below can display the operation state of the elevator by the visualization processing performed by the visualization processing unit 34. In particular, the visualization processing unit 34 creates visualization data for visualizing the cause of deterioration, the estimated factor, the improvement method, and the classification of the improvement method based on the analysis processing by the operation state analysis processing unit 33.

The data format of the visualized data created by the visualization processing unit 34 is not particularly limited, but for example, an image format, an HTML format, an XML format, a CSV format, or the like can be employed. The details of the operation state of the elevator displayed by the visualization processing performed by the visualization processing unit 34 are described in detail below with respect to the terminal device 40 and the method of visualizing the operation state of the elevator.

[ usability Specification data transmitting section 35]

When the collective processing unit 32 acquires a method of improvement in the system related to the control of the elevator based on the analysis result of the operation state analysis processing unit 33, the usability specification data transmitting unit 35 creates usability specification change data according to the method of improvement. The usability specification data transmitting unit 35 is a part that transmits the created usability specification change data to the combination management device 21 of the corresponding building. Details of the processing performed by the usability specification data transmitting unit 35 are described in detail below in the elevator control method.

< terminal device 40 >

The terminal device 40 is an information processing terminal owned by a customer, and includes a display unit, an operation unit, and a communication interface. The operation unit may be a touch panel provided on the front surface of the display unit, in addition to the keyboard and the mouse. Specific examples of such a terminal device 40 are not particularly limited, and a personal computer, a tablet computer, a smartphone, and the like are suitable, for example.

The display unit of the terminal device 40 displays the operation state of the elevator based on the visualized data created by the visualization process of the visualization processing unit 34. The operating state of the elevator is displayed as a part of a building information screen. Fig. 8 is (a) a display example of a building information screen 301 according to the embodiment. Fig. 9 is a display example (second) of a building information screen 301 according to the embodiment.

As shown in these figures, the building information screen 301 displayed on the display unit of the terminal device 40 by the processing of the visualization processing unit 34 includes a building information display selection area 3011, an operation state display field 3012, a date and time information selection field 3013, a [ display ] button 3014, a deterioration information display field 3015, an improvement method display field 3016, an [ execute ] button 3017, and an operation state chart display field 3018.

The building information display selection area 3011 includes a "building name" column, a "combination name" column, and radio buttons for selecting a combination of visual objects. The radio button can select all combinations displayed in the "combination name" column.

The operation state display field 3012 displays, for example, any one of "operation state deterioration" and "operation state good" based on the analysis result of the operation state analysis processing unit 33 for the combination selected by the radio buttons of the building information display selection area 3011.

When the operation state is detected to be deteriorated by the analysis of the operation state analysis processing unit 33 for the combination selected by the radio buttons of the building information display selection area 3011, the date and time information selection field 3013 displays the date and time information that enables all the operation state deterioration detection to be selected.

Further, when the deterioration of the operation state is detected by the analysis of the operation state analysis processing unit 33 for the combination selected by the radio buttons in the building information display selection area 3011, a [ display ] button 3014 is displayed.

The deterioration information display field 3015 displays the cause of deterioration and the estimated factor extracted by the visualization processing unit 34. The improvement method display column 3016 displays the improvement methods extracted by the visualization processing unit 34 separately as a method related to the operation of the elevator and a method related to the system (usability specification) of the elevator. Further, an [ execute ] button 3017 is displayed in conjunction with display of a method related to the system (usability specification) of the elevator.

The operating state chart display field 3018 displays at least an evaluation chart 3018a when the deterioration of the operating state is not detected in a normal state (or in a good state) and an evaluation chart 3018b when the deterioration of the operating state is detected in a vertical direction. This makes it possible to confirm the degree of deterioration at a glance.

These

evaluation charts

3018a and 3018b are created based on data of a group of identified causes of deterioration with respect to data of a combination in which deterioration of the operating state is detected in the analysis processing of the operating state analysis processing unit 33.

Such evaluation charts

3018a and 3018b are, for example, two-dimensional charts in which the first axis is a value for detecting a cause of deterioration (cause item) of deterioration of the operating state such as an average waiting time, and the second axis orthogonal to the first axis is time. The second axis is, for example, a 24-hour time division so as to contain data of the deterioration detection date and time of the operating state. These

evaluation charts

3018a and 3018b include an evaluation threshold 3018 c.

In addition, the first axis may also be the value of the factor term. In addition, as each of the

evaluation charts

3018a and 3018b, two kinds of charts may be displayed, that is, a chart in which the first axis is a deterioration factor (a factor item) and a chart in which the first axis is a factor item.

Fig. 8 and 9 show an example of the case where the average waiting time is detected as the cause of deterioration of the operating state, and two-dimensional graph data is displayed with the vertical axis as "average waiting time (seconds)" and the horizontal axis as time. As an example of the graph data, the evaluation graph 3018a (graph data) at the time of normal operation shows the transition of the average waiting time of 2019/01/06(24 hours), and the evaluation graph 3018b (graph data) at the time of deterioration shows the transition of the average waiting time of 2019/01/07(24 hours).

The procedure of display on the display unit of the terminal device 40 as described above is described in detail in the following method for visualizing the operation state of the elevator and method for controlling the elevator.

Method for visualizing running state of elevator and method for controlling elevator

Fig. 10 is (one of) a flowchart showing a method for visualizing an elevator operation state and a method for controlling an elevator according to the embodiment, and is a diagram showing an analysis process of an elevator operation state performed by the operation state analysis processing unit 33 of the visualization device 30 shown in fig. 2. Fig. 11 is a flowchart (second) showing a method for visualizing an operation state of an elevator and a method for controlling an elevator according to the embodiment, and is a diagram showing a process for visualizing an operation state and a process for controlling an elevator, which are performed by the visualization device 30 and the terminal device 40 shown in fig. 2.

Hereinafter, an embodiment of a method for visualizing an elevator operation state and an elevator control method according to an embodiment will be described with reference to the essential drawings of fig. 2 to 9 in the order of flowcharts shown in fig. 10 and 11.

< analysis processing of operating State >

First, an analysis process of the operation state of the elevator will be described with reference to fig. 10.

[ step S101]

In step S101, the operation state analysis processing unit 33 determines whether or not the time at which the analysis processing is executed has come. Here, the operation state analysis processing unit 33 may perform the analysis processing of the operation state periodically such as 1 time per day, or may perform the determination by an elapsed time after the analysis processing was performed last time. The elapsed time may coincide with a predetermined period (for example, 1 day) during which the combination management device 21 collects the operation information. The analysis processing time may be set in accordance with the time at which the collected operation information is transmitted from the combination management device 21 to the storage device 31 of the visualization device 30. When determining that the analysis processing time has reached (yes), the operation state analysis processing unit 33 proceeds to the next step S102, and waits until determining that the analysis processing time has reached (yes).

[ step S102]

In step S102, the operation state analysis processing unit 33 refers to the operation information DB31d, and determines whether or not there is newly registered data in the operation information DB31d after the time when the previous analysis processing was executed. If it is determined that there is (yes), the process proceeds to step S103. On the other hand, if it is determined that the information is not present (no), the process is terminated.

[ step S103]

In step S103, the operation state analysis processing unit 33 causes the summary processing unit 32 to perform a process of summarizing (e.g., integrating, averaging) the (25) pieces of operation information registered in the operation information DB31d for a summary period (e.g., 5 minutes, 15 minutes, 30 minutes) specified in advance by the system manager. Further, in the case where the total period specified by the system manager is the same as the time range in the (23) date-and-time information in the operation information DB31d, the operation state analysis processing section 33 skips this processing and proceeds to the following step S104.

[ step S104]

In step S104, the operation state analysis processing unit 33 performs a determination process of each evaluation item of the evaluation level 1 registered in the analysis condition DB31b based on (25) operation information registered in the operation information DB31 d. At this time, the operation state analysis processing unit 33 extracts information corresponding to the evaluation item of the evaluation level 1 registered in the analysis condition DB31b from all (25) pieces of operation information registered in the operation information DB31d, or calculates information corresponding to the evaluation item of the evaluation level 1 from the extracted operation information.

The operation state analysis processing unit 33 compares the extracted or calculated value of each evaluation item with the (8) evaluation threshold value set for each evaluation item of the evaluation level 1 registered in the analysis condition DB31 b. Then, a determination is made as to whether or not the evaluation threshold is exceeded (8) for all the extracted or calculated evaluation items.

[ step S105]

In step S105, as a result of the comparison in step S104, the operating condition analysis processing unit 33 determines that deterioration of the operating condition is detected (yes) even if there is one evaluation item having the evaluation level 1 exceeding the (8) evaluation threshold. If it is determined that the detection (yes) is detected, the process proceeds to the following step S106. On the other hand, if the comparison result in step S104 indicates that there is no evaluation item of the evaluation level 1 exceeding (8) the evaluation threshold, the operating state analysis processing unit 33 determines that the deterioration of the operating state is not detected (no), and ends the processing.

Here, in the example of the operation information DB31d shown in fig. 6, (B) the average waiting time "55 seconds" in (25) operation information stored in association with (4) the building ID "building a", "21) the combination ID" combination B ", … exceeds (8) the evaluation threshold value" 50 seconds "registered in the analysis condition DB31B of fig. 4. Therefore, it is determined that the deterioration of the operating state is detected (yes), and the process proceeds to step S106.

[ step S106]

In step S106, the operation state analysis processing unit 33 performs a determination process of each evaluation item of the evaluation level 2 registered in the analysis condition DB31b based on (25) operation information registered in the operation information DB31d shown in fig. 6. Here, the determination process is performed for the evaluation item of the evaluation level 2 corresponding to the same deterioration factor as the evaluation item of the evaluation level 1 exceeding the evaluation threshold in the comparison of step S104.

For example, in the example of the operation information DB31d shown in fig. 6, (B) the average waiting time "55 seconds" in (25) operation information stored in association with (4) the building ID "building a", "21) the combination ID" combination B ", and … exceeds the evaluation threshold. Therefore, information corresponding to the evaluation item of the evaluation level 2 corresponding to (5) the deterioration cause "average waiting time" registered in the analysis condition DB31b of fig. 4 is extracted or calculated from the operation information DB31 d.

The operating condition analysis processing unit 33 compares the extracted or calculated value of each evaluation item with the (8) evaluation threshold value set for each evaluation item of the evaluation level 2 registered in the analysis condition DB31b of fig. 4. Then, a determination is made as to whether or not each evaluation item exceeds (8) the evaluation threshold, and the evaluation item exceeding (8) the evaluation threshold is extracted as a factor that deteriorates the operating state.

[ step S107]

In step S107, the operating condition analysis processing unit 33 registers (7) evaluation items extracted as factors that deteriorate the operating condition in the analysis result DB31e shown in fig. 7 in association with (4) the building ID, (21) the combination ID, (23) the date and time information, (31) the deterioration detection date and time, and (5) the cause of deterioration. Further, it is assumed that (31) the deterioration detection time is a time for performing the analysis processing shown in the flow of fig. 10.

< visualization of operating state and control of elevator >

Next, the procedure of the visualization process of the operation state of the elevator and the control process of the elevator will be described with reference to other drawings as necessary based on fig. 11. The sequence shown in fig. 11 is a sequence implemented in the visualization device 30 and the terminal device 40 shown in fig. 2. In the following description, it is assumed that the visualization device 30 functions as a Web server and a Web browser is installed in the terminal device 40. However, it is also possible to assume that the visualization device 30 and the terminal device 40 constitute a client & server type system, and a dedicated program is installed in the terminal device 40.

In fig. 11, steps S301 to S309 show processes performed in the respective sections of the visualization device 30. Steps S401 to S406 show processes performed by the terminal device 40. Further, steps S41 to S43 show the processing of the operation of the terminal device 40 by the client.

[ step S41]

First, in step S41, the client having the terminal device 40 performs a login operation through the terminal device 40. In this case, the client inputs the user ID and the password assigned to the client on the login page of the terminal device 40. At this time, for example, the client inputs the user ID "001" and the password "abc" through the terminal device 40. In the following, it is assumed that the terminal device 40 is the terminal device 40 of the client who performed the login operation in step S41.

[ step S401]

In step S401, the terminal device 40 having performed the login operation transmits the user ID and the password input in step S41 to the visualization device 30 as login information.

[ step S301]

In step 301, the visualization processing unit 34 of the visualization device 30 that has received the registration information reads out the building ID corresponding to the received user ID and password from the user DB31a (see fig. 3). Then, the visualization device 30 creates visualization data for the building information screen based on the read building ID.

At this time, for example, when the visualization device 30 receives the user ID "001" and the password "abc", the visualization processing unit 34 reads the building IDs "building a" and "building B" registered in association with the user ID "001" from the user DB31a (see fig. 3).

Then, the visualization processing unit 34 extracts information registered in association with the building IDs "building a" and "building B" from the analysis result DB31e (see fig. 7), and generates a building information screen based on the information. Further, the analysis result DB31e (see fig. 7) may not register the building IDs "building a" and "building B".

[ step S302]

Then, in step S302, the visualization processing unit 34 transmits the visualization data of the building information screen created in step S301 to the terminal device 40 of the transmission source of the user ID and the password received in step S301.

[ step S402]

In step S402, the terminal device 40 that has received the visualized data of the building information screen displays the building information screen on the display unit based on the received building information screen data. Here, as shown in fig. 8, the information read in step S301 is displayed in the "building name" column, the "combination name" column, and the operation state display column 3012 of the building information display selection area 3011 on the building information screen 301.

For example, the building IDs "building a" and "building B" read in step S301 are displayed in the "building name" column. In the column of "combination name", the combination IDs "combination a", "combination B", and "center combination" possessed by the building management devices 20 installed in the building IDs "building a" and "building B" are displayed in association with the building IDs.

In this state, selection of all combinations displayed can be switched by checking the radio buttons in the building information display selection area 3011. In the example of fig. 8, the "combination B" of the "building a" is selected.

In addition, the operation state of the elevator in the "combination B" selected in the building information display selection area 3011 is displayed in the operation state display field 3012. In this case, if there is information corresponding to the selected "combination B" among the information extracted from the analysis result DB31e (see fig. 7) in step S301, the "operation state deterioration" is displayed in the operation state display field 3012.

On the other hand, if there is no information corresponding to the "combination B" selected in the building information display selection area 3011 from the information extracted from the analysis result DB31e (see fig. 7) in step S301, the "good running state" is displayed in the running state display field 3012.

In addition, when the display of the operation state display field 3012 is "operation state deterioration", the date and time information selection field 3013 displays, as display selection, all the date and time information items for which the deterioration of the operation state is detected for "combination B" selected in the building information display selection area 3011. In the example of fig. 8, the date and time information "2019/01/0712: 00 to 12: 15" is selected.

The [ display ] button 3014 is displayed when the display of the operating state display field 3012 is "operating state degraded", and is not displayed when the display of the operating state display field 3012 is "operating state good".

In this state, the deterioration information display field 3015, the improvement method display field 3016, the [ execute ] button 3017, and the operation state graph display field 3018 are not displayed. However, only the evaluation chart 3018a during normal operation may be displayed in the operation state chart display field 3018 as a default display, and only the axis of the chart may be displayed in the display field of the evaluation chart 3018b during deterioration operation.

In addition, if the information extracted from the analysis result DB31e (see fig. 7) in step S301 is not displayed in all combinations of the building information display selection areas 3011, the [ display ] button 3014 is not displayed. In this case, all the following steps are skipped.

[ step S42]

In the above display state, when the [ display ] button 3014 of the building information screen 301 displayed on the display unit of the terminal device 40 is clicked by the client in step S42, the operation becomes an input of a display instruction by the client.

[ step S403]

In step S403, the terminal device 40 requests the visualization device 30 for visualization data for displaying the deterioration information, the improvement method, and the operation state diagram in response to the [ display ] button 3014 being clicked. At this time, the terminal device 40 transmits, as the request for the visualized data, the information selected in the display in step S402, that is, the building ID and the combination ID selected in the building information display selection area 3011 and the date and time information selected in the date and time information selection field 3013, to the visualizing device 30 as the selection information.

Here, as an example, the terminal device 40 transmits the building ID "building a", the combination ID "combination B", and the date and time information "2019/01/0712: 00 to 12: 15" to the visualization device 30 as the selection information.

[ step S303]

In step S303, the summary processing unit 32 of the visualization device 30 acquires (9) the estimation factor, (10) the improvement classification, and (11) the improvement method registered in the improvement method DB31c, based on the selection information transmitted from the terminal device 40. In this case, the summary processing unit 32 first acquires information corresponding to the selection information transmitted from the terminal device 40 from the information registered in the analysis result DB31 e. The information acquired here is (5) the deterioration cause "average waiting time" and (7) the evaluation item "hall call registration ratio" registered in association with the building ID "building a", the combination ID "combination B", and the date and time information "2019/01/0712: 00 to 12: 15" received as the selection information.

Next, the summary processing unit 32 acquires (9) the estimation factor, (10) the improvement classification, and (11) the improvement method registered in association with (5) the deterioration cause "average waiting time" and (7) the evaluation item "hall call registration ratio", from the information registered in the improvement method DB31 c.

[ step S304]

In step S304, the collection processing unit 32 of the visualization device 30 collects data for creating the operation state chart from the information registered in the operation information DB31 d. In this case, the summary processing unit 32 collects data corresponding to the building ID "building a" and the combination ID "combination B" in the selection information transmitted from the terminal device 40, which is obtained in step S303 and corresponds to (5) the deterioration cause "average waiting time" from (25) operation information registered in the operation information DB31 d.

The data collected here is data at the time of deterioration of 2019/01/07 hours including date and time information "2019/01/0712: 00 ~ 12: 15" received as selection information. Here, the data in the normal state for 24 hours in which the deterioration of the operation state is not detected may be collected, for example, 24-hour data of 2019/01/06 days before.

[ step S305]

In step S305, the visualization processing unit 34 of the visualization device 30 creates 2 pieces of chart data based on the selection information transmitted from the terminal device 40 and the data collected by the processing unit 32 in step S304. The visualization processing unit 34 creates graph data for displaying an evaluation chart in a normal state based on the data in a normal state collected by the collection processing unit 32. The visualization processing unit 34 creates graph data for displaying an evaluation chart during deterioration based on the data during deterioration collected by the collection processing unit 32. In addition, when the normal evaluation chart is displayed on the terminal device 40 by default, it is not necessary to create chart data for displaying the normal evaluation chart.

[ step S306]

In step S306, the visualization processing unit 34 of the visualization device 30 transmits (5) the cause of deterioration, (9) the estimated factor, (10) the improvement classification, (11) the improvement method, and the 2 pieces of chart data created in step S305, which have been acquired in step S303, to the terminal device 40.

[ step S404]

In step S404, as shown in fig. 9, the terminal device 40 displays (5) the cause of deterioration, (9) the estimated factor, (10) the improvement classification, (11) the improvement method, and 2 pieces of chart data, which are received from the visualization device 30, on the building information screen 301.

That is, the terminal device 40 displays (5) the deterioration cause "average waiting time" and (9) the estimation factor received from the visualization device 30 in the deterioration information display field 3015 of the building information screen 301. In addition, the improvement method display field 3016 displays (11) an improvement method corresponding to the (10) improvement classification "operation" as a method related to the operation of the elevator. In addition, as a method related to the system (usability specification) of the elevator, a (11) improvement method corresponding to the (10) improvement division "system" is displayed (refer to the improvement method DB31c of fig. 5).

Then, the terminal device 40 displays the [ execute ] button 3017 in conjunction with display of a method related to the system (usability specification) of the elevator.

In the operation state chart display field 3018 of the building information screen 301, the terminal device 40 displays the normal evaluation chart 3018a and the deterioration evaluation chart 3018b in parallel in the top-bottom direction on the basis of the 2 chart data received from the visualization device 30.

[ step S43]

In step S43, when the [ execute ] button 3017 of the building information screen 301 displayed on the display unit of the terminal device 40 is clicked by the customer, the operation is an input of an execution instruction for changing the usability specification (elevator system) by the customer.

[ step S405]

In step S405, the terminal device 40 transmits an instruction to change the usability specification to the visualization device 30 in response to the [ execute ] button 3017 being clicked.

[ step S307]

In step S307, the usability standard data transmitting unit 35 of the visualization device 30 creates change data for changing the usability standard in accordance with the usability standard change instruction received from the terminal device 40. The modified data created here is data for implementing the improvement method displayed in the method column relating to the elevator system (usability specification) in the improvement method display column 3016 shown in fig. 9.

[ step S308]

In step S308, the availability specification data transmission unit 35 of the visualization device 30 transmits the created change data of the availability specification to the corresponding combination management device 21, for example, the combination management device 21B (see fig. 2) of the elevator that manages the "combination B" of the "building a". Thereby, the combination management device 21b transmits the change data of the availability specification to the elevator control devices 10d, 10e, and 10f connected to the combination management device 21 b.

The elevator control devices 10d, 10e, and 10f store the received change data of the availability specifications as it is, or change the system of the elevator based on the change data.

[ step S309]

In step S309, the usability specification data transmitting unit 35 transmits the transmission result of the usability specification change data to the combination management device 21b to the terminal device 40, and ends the series of processing of the visualization device 30.

[ step S406]

On the other hand, in step S406, the terminal device 40 displays the transmission completion of the changed data of the usability specification on the display unit. The terminal device 40 displays the transmission result of the usability specification data received from the visualization device 30. The result of transmitting the usability specification data may be displayed on the building information screen 301 or may be displayed on the pop-up window.

Effect of the embodiment

According to the embodiment described above, when the deterioration of the operating state of the elevator is detected in the operating state analysis processing unit 33 of the visualization device 30, the visualization processing unit 34 creates visualized data for visualizing the cause of deterioration and the factor of deterioration of the operating state and the improvement method. This enables the display of the information on the display unit of the client terminal device 40. As a result, even a customer who does not have professional knowledge relating to elevator control can easily know the improvement method when the elevator operation state is deteriorated, and the customer can perform the improvement method.

In particular, the operation information DB31d has operation information registered therein for each combination and for each date and time information, and the operation state analysis processing unit 33 analyzes the operation state based on the operation information registered in the operation information DB31 d. Therefore, the deterioration of the running state of the elevator can be detected in combination, and the improvement method can be obtained according to the cause of the deterioration. Therefore, even if professional knowledge relating to group management control of the elevators is not available, the method for improving the deterioration of the operation state of the group management elevators can be easily known, and even if the clients such as a building management company and a building owner who do not have professional knowledge, the method for improving the deterioration of the operation state can be easily realized.

Modifications of the examples

In the above-described embodiment, the configuration of the [ execute ] button 3017 for displaying the display unit of the terminal device 40 to request transmission of the change data of the usability specification has been described, but an [ invalidate ] button for invalidating the change of the usability specification may be further displayed. In this case, when the [ invalid ] button is clicked by the customer, the change of the usability specification is cancelled, and the usability specification of the elevator returns to the reference state.

In the present embodiment, the horizontal axes of the normal evaluation chart 3018a and the deterioration evaluation chart 3018b are described on a 24-hour scale, but may be variable. The evaluation chart 3018a and the evaluation chart 3018b may be displayed in other forms such as a bar chart.

In the present embodiment, the case has been described in which the combination management device 21 transmits the operation information for each predetermined time period collected for 1 day as the predetermined period to the visualization device 30, and the data of the evaluation items are collected for the collection period (for example, 5 minutes, 15 minutes, 30 minutes) specified by the system manager using the data of 1 day as the overall parameter. However, the data of the evaluation items may be summarized as the overall parameter, using data of 5 days of monday to friday in which the building is operated.

In the present embodiment, the evaluation thresholds included in the evaluation graph 3018a and the evaluation graph 3018b are described as one, but an additional evaluation threshold may be added for warning. Note that the alert can prevent customer complaints by, for example, signaling to a maintenance company or the like.

The present invention is not limited to the above-described embodiments and modifications, and various modifications are also included.
