Further, the computer C has a display unit C5, an operation unit C6, a nonvolatile storage C7 and a network interface C8, which are connected to the bus C4.

The CPU C1 reads predetermined program codes from the ROM C2 storing program codes of software for realizing various functions of the computer C to the RAM C3 and executes them. At this time, variables and parameters generated in the course of arithmetic processing by the CPU C1 are also temporarily written to the RAM C3.

The display unit C5 is composed of a display device such as a liquid crystal display, for example, and displays information such as the result of processing performed by the computer C on the display screen to notify the user. The operation unit C6 is composed of, for example, an operation device such as a keyboard and a mouse, and allows the user to perform predetermined operation inputs and instructions to the computer C.

Then, the CPU C1 reads the program code for displaying the operation status stored in the ROM C2 into the RAM C3, and executes the program code to display the operation status (various element models) displayed on the operation screen 21 described later. ) is displayed and changed.

[Calculation part]
The calculation unit 1 is a component that performs display control of the operating state of the elevator, and has a model change request generation unit 11 (change instruction generation unit) and a model drawing unit 12 (drawing unit) as functional blocks.

The model change request generating unit 11 generates various information related to the operating state of the elevator stored in the building operating state managing unit 31 described later, and a model change request list stored in the model change request list storing unit 32 (described later). 3) is obtained as input data. Next, based on these input data, the model change request generator 11 needs to highlight (change) at least some of the various element models described later displayed on the operation screen 21 described later. If so, it generates a model change request signal (instruction) corresponding to the change. Then, the model change request generation unit 11 outputs the generated model request change signal to the model drawing unit 12 . The specific contents of the process of generating the model request change signal by the model change request generating unit 11 will be described in detail later.

The model drawing unit 12 stores various information about the operation status of the elevator stored in the building operation status management unit 31, which will be described later, and various element models necessary for the display configuration of the operation screen 21, which are stored in the element model storage unit 33, which will be described later. (see FIG. 4 described later) are acquired as input data. Based on these input data, the model drawing unit 12 generates drawing (display) data for an operation screen 21 showing the ever-changing operating state of the elevator, and outputs the data to the display unit 2 .

In addition, when a predetermined event (problem) such as congestion occurs in the operating state of the elevator, the model rendering unit 12 also stores the event data from the model change request generation unit 11 to the model rendering unit 12 in addition to the various data described above. A model request change signal corresponding to is input. Then, when the model request signal is input, the model drawing section 12 changes the display mode of the element model related to the occurrence (place of occurrence) of the predetermined event. Specifically, the model drawing unit 12 emphasizes the data of the display mode of the element model to be changed in the normal state (when no problem occurs) according to the content of the input model request change signal. The data is changed to data in a display mode that can be displayed, and drawing data for the operation screen 21 after the change is generated. When the model request change signal is not input, the model drawing unit 12 does not display the change of the element model, and generates drawing data showing the current operation state in the normal display mode of the element model. and output to the display unit 2.

[Display part]
The display unit 2 has an operation screen 21 , and displays the operation state (operating status) of the elevator on the operation screen 21 based on the drawing data input from the model drawing unit 12 . In addition, the display mode of the operation state of the elevator displayed on the operation screen 21 will be described in detail later.

[Data Management Department]
The data management unit 3 has a building operation state management unit 31 , a model change request list storage unit 32 and an element model storage unit 33 .

(1) Building Operation Status Management Section The building operation status management section 31 stores (manages) various information indicating the operation status of each facility (elevator, etc.) in the building. In this embodiment, the building operation state management unit 31 includes at least an elevator operation state storage unit 34 that stores various types of information (first information) indicating the operation state of elevators.

The static information indicating the operating status of the elevator stored in the elevator operating status storage unit 34 includes at least information such as the capacity of each elevator, the rated speed, the number of elevators, and the like.

The dynamic information indicating the operation state of the elevator includes at least information such as the position, speed, door open state (door open/closed state) of each elevator at each time, for example. In addition, dynamic information indicating the operation status of the elevator includes, for example, presence or absence of button operation (so-called "hall call") performed by the elevator user when calling the elevator in the elevator hall, the duration of the hall call, and the like. Information may be included. The "hall call continuation time" is the time from when the service to the hall call generation floor is assigned to the elevator until the service to the hall call generation floor is actually performed. That is, the "hall call duration time" is the time from when the user of the elevator performs the hall call operation to when the elevator arrives at the floor where the hall call is generated. Furthermore, as dynamic information indicating the operation status of the elevator, for example, information such as presence or absence of button operation (so-called "car call") performed by the user when registering the destination floor in the elevator car, and information such as the number of passengers. may be included.

Various types of information indicating the operation state of the elevator stored in the elevator operation state storage unit 34 are appropriately changed according to the application of the operation state display device 100 of the present embodiment.

For example, when the operation state display device 100 is used as a simulator for the purpose of designing and evaluating an elevator operation plan, various information preset by a designer or the like as various information indicating the operation state of the elevator may be used. Further, when the operating state display device 100 is used as a simulator, as various information indicating the operating state of the elevator, various data relating to the operating state obtained during actual operation in the past may be used.

On the other hand, for example, when the operation state display device 100 of the present embodiment is used on site (actual operation), real-time various information is stored in the elevator operation state storage unit 34 as various information indicating the operation state of the elevator. may be configured. Further, even when the operation state display device 100 is used on site, for example, when used for the purpose of analyzing the past operation state, improving operation, etc., the past (for example, the past several days) operation Various types of information about the state may be stored in the elevator operation state storage unit 34 .

(2) Model change request list storage unit and model change request list The model change request list storage unit 32 stores a model change request list (table). Here, FIG. 3 shows an example of the model change request list stored in the model change request list storage unit 32. As shown in FIG. In this model change request list, each list number (No. "1" to "5") defines a data set in which model change conditions (third information) and details of the model change request are combined as one set. be done. Note that the model change condition can be arbitrarily set as long as it can be detected (determined whether the condition is met or not met) based on various information that can be acquired from the building operation state management unit 31 .

The model change request list shown in FIG. 3 is an example of a model change request list used for the purpose of estimating the cause of the phenomenon (problem) that the waiting time of an elevator increases. The model change request list may be created separately for each event type that may occur, or the model change request lists for all event types may be compiled into one list. For example, events (problems) other than the increase in elevator waiting time include events such as an increase in power consumption. Also, when a plurality of elevators are installed in a building, a model change request list may be created for each elevator, or model change request lists for all elevators may be compiled into one list.

In the "model change condition" column in the model change request list shown in FIG. 3, a condition (event) that is a cause candidate for an increase in waiting time of the elevator is defined. In addition, in the "model change request" column in FIG. 3, the element model to be changed ("change model" column) and the content of change in the display mode of the element model ("change content" column) are associated with each other. Defined (with string).

In this embodiment, for example, a car model, a door model, a floor model, a human model, a hoistway model, etc. are prepared as element models. The car model is a model representing an elevator car displayed on the operation screen 21, and the door model is a model representing an elevator door provided in the elevator hall of each floor displayed on the operation screen 21. be. The floor model is a model representing the floor of the elevator hall displayed on the operation screen 21, and the person model is a model representing a person present in the car and on the elevator hall displayed on the operation screen 21. The hoistway model is a model representing the hoistway of each elevator displayed on the operation screen 21 .

In the data set with list number "1", for the model change condition that "elevator travel time is longer than the traffic calculation value", the changed model and change details are "elevator hoistway model" and "lighten model color", respectively. Change to red" is associated. Therefore, when the model change condition of the list number "1" is established, the color of the hoistway model of the elevator on the operation screen 21 changes to pale red.

In the data set with list number "2", for the model change condition that "the elevator door open time is longer than the traffic calculation value", the changed model and change details are "elevator door model" and "light model color", respectively. Change to red" is associated. Therefore, when the model change condition of list number “2” is satisfied, the color of the elevator door model on the operation screen 21 changes to pale red.

In the data set of list number "3", for the model change condition that "elevator getting on and off time is longer than the traffic calculation value", the change model and change contents are "elevator door model and car model" and "model color to light red" is associated. Therefore, when the model change condition of the list number "3" is satisfied, the color of the elevator door model and car model both change to light red on the operation screen 21 . Although this example shows an example in which the colors of both the door model and the car model are changed when the elevator boarding/alighting time is longer than the traffic calculation value, the present invention is not limited to this. If the elevator boarding/alighting time is longer than the traffic calculation value, the color of either the door model or the car model may be changed.

The "traffic calculation value" specified in the model change conditions for list numbers "1" to "3" is the travel calculated based on a predetermined formula when information such as the capacity and rated speed of the elevator is given. time, door open time (door open time), boarding and alighting time, and approximate values of the number of passengers transported in 5 minutes. By detecting the occurrence of a deviation between these traffic calculation values and the information obtained from the building operation state management unit 31 (information regarding the state of the predetermined operation of the elevator), the cause of the increase in waiting time of the elevator is specified. can be done.

In the data set of list number "4", for the model change condition "Elevator is not moving for a long time", the changed model and change details are "elevator car model" and "change model color to blue" respectively. is associated. Therefore, when the model change condition of list number "4" is satisfied, the color of the elevator car model on the operation screen 21 changes to blue. Whether or not the model change condition specified in list number "4" is met is determined by comparing the time during which the elevator is not moving (non-moving time) with a predetermined threshold value. By providing this model change condition, it is possible to detect that the elevators cannot be operated efficiently due to, for example, setting errors during elevator group management.

The data set with list number "5" defines a model change condition that "a plurality of elevators exist within a certain range". Then, in the data set with list number "5", for this model change condition, the change model and change details are "the hoistway model of the elevator existing within the range" and "change the existing range of the elevator to pale yellow", respectively. ” is associated. Therefore, when the model change condition of list number "5" is satisfied, the color of the hoistway model in a certain range (predetermined range) where a plurality of elevators exist on the operation screen 21 changes to pale yellow.

It is known that when a plurality of elevators move in the same direction at the same time in the same position (height position), there is a bias in service, which tends to increase the waiting time. Therefore, the model change condition of list number "5" can be used to detect this event (phenomenon). The data set with list number "5" is specified when there are multiple elevators (hoistways) in the building. The data set numbered "5" is not specified in the model change request list.

In the example shown in FIG. 3, when at least one of the model change conditions of list numbers "1" to "5" is satisfied at a certain time (when an elevator waiting time rises), the model change request generation unit 11 , a model change request is output to the model drawing unit 12 . At this time, the output model change request signal includes the changed model associated with the satisfied model change condition (list number) and the information on the change details. Next, the model drawing unit 12 changes the drawing data of the model to be changed, based on the information about the changed model and the change content included in the input model change request signal. As a result, when at least one of the model change conditions of list numbers "1" to "5" is satisfied at a certain time, the display mode of the element model to be changed is displayed in the model drawing unit 12 on the operation screen 21. The display mode changes to correspond to the content of the input model change request signal. This makes it possible to reflect (highlight) the occurrence of an event that is a candidate for the cause of an increase in waiting time for the elevator on the operation screen 21 .

In the example shown in FIG. 3, the traffic calculation value is used as the threshold value for determining whether the model change conditions defined by the list numbers "1" to "3" are satisfied. It is not limited to this, and an arbitrary threshold value can be set appropriately as needed. For example, a predetermined value may be used instead of the traffic calculation value.

Further, in the example shown in FIG. 3, the model change request list defines the candidate cause of the problem (phenomenon) as the model change condition, but the present invention is not limited to this. An arbitrary condition when it is necessary to change the display mode of the element model due to a factor other than the occurrence of a problem may be set as the model change condition. For example, in the model change request list, various conditions for problem solving may be used as model change conditions. In this case, a model change request signal is output from the model change request generation unit 11 to the model drawing unit 12 if a predetermined problem solving condition is satisfied. Based on the model change request signal, the model drawing unit 12 changes (restores) the display mode of the corresponding element model from the display mode when a problem occurs to the display mode when no problem occurs (normal time). .

In addition, in the example shown in FIG. 3, an example of changing the color of the element model to be changed has been described as an example of changing the display mode of the element model. Any modification can be applied as long as it can be displayed. For example, flashing the element model to be changed, changing the shape and/or size of the element model to be changed, displaying some characters, symbols, etc. that indicate the occurrence of an event on or near the element model, etc. Modifications may apply. Further, for example, these modification modes, modification modes of the present embodiment (change of model color), etc. may be appropriately combined.

The contents (types, etc.) of the model change conditions specified in the model change request list may be appropriately optimized according to the equipment, structure, etc. in the building to which the operation status display device 100 is applied. In addition, for at least some of the model change conditions specified in the model change request list (for example, the model change condition of list number "5" in Fig. 3), regardless of the equipment, structure, etc. A common configuration may be adopted.

In the example shown in FIG. 3, light red, blue, or light yellow is set as the color of the element model after change. You can set any color other than the color of

(3) Element model storage unit The element model storage unit 33 stores data (second information) of a group of parts of various element models (operation screen constituent element models: elements) necessary for configuring the operation screen 21. . In this embodiment, as described above, for example, a car model, a door model, a floor model, a human model, a hoistway model, etc. are prepared as element models. Each element model includes at least one of a three-dimensional model (virtual three-dimensional object) and a two-dimensional model. The three-dimensional model displayed on the operation screen 21 is generated using, for example, polygon data.

The element model may also include a three-dimensional model representing the configuration of the floor, walls, etc. of the building (elevator hall). Further, the element models stored in the element model storage unit 33 may include various models used in BIM (Building Information Modeling). In this case, as the drawing process of the model by the model drawing unit 12, the drawing process conforming to the drawing process used in BIM can be used.

[Example of operation screen display]
FIG. 4 shows an example of the operation screen 21 displayed on the elevator operation state display device 100 of the present embodiment. Note that FIG. 4 is a configuration example of the operation screen 21 that displays the operation state of the elevator during normal operation (when no problem occurs). Further, FIG. 4 shows an example in which the number of elevators installed in the building is three (elevators E1, E2, E3) and the number of floors of the building is three.

The operation screen 21 of this example includes a car model 40 of each elevator, a door model 41 and a floor model 42 of the elevator in the elevator hall of each floor, and a human model 43 representing users existing in the car and on the elevator hall. Configured. In addition, in the example of the operation screen 21 shown in FIG. 4, illustration of the hoistway model of each elevator is omitted for convenience of explanation.

The operation screen 21 of this example shows a state where the elevator has not arrived at the first floor and all the doors of the elevator hall on the first floor are closed. Further, the operation screen 21 of this example shows a state in which the elevator E2 exists between the first floor and the second floor, and two passengers are present in the car of the elevator E2.

Further, the operation screen 21 of this example shows a state in which the elevator E1 has arrived at the second floor and only the doors of the elevator E1 are open in the elevator hall on the second floor. Further, in the operation screen 21 of this example, in the elevator hall on the second floor, one user exists (waits) in front of the door of the elevator E1, and one passenger exists in the car of the elevator E1. state is shown.

Further, the operation screen 21 of this example shows a state in which the elevator E3 has arrived at the third floor and only the doors of the elevator E3 are open in the elevator hall on the third floor. Furthermore, in the operation screen 21 of this example, in the elevator hall on the third floor, there are two users (waiting) in front of the door of the elevator E3 and one passenger in the car of the elevator E3. state is indicated.

[Display control of operation screen]
Next, the contents of display control (including change display control) of the operation screen 21 by the operation state display device 100 of this embodiment will be described with reference to FIGS. 5 and 6. FIG. FIG. 5 is a flow chart showing the procedure of model change request generation processing performed by the operation state display device 100 of the present embodiment. Moreover, FIG. 6 is a flowchart which shows the procedure of the operation state drawing process performed by the operation state display apparatus 100 of this embodiment. 5 and 6, during operation of the operation state display device 100, the operation state (operation state) of the elevator, which changes from moment to moment, can be displayed substantially continuously. It is repeated at intervals of time.

First, referring to FIG. 5, the model change request generating process executed by the model change request generating unit 11 (calculating unit 1) will be described. First, the model change request generation unit 11 generates various information about the elevator operation state stored in the building operation state management unit 31 (elevator operation state storage unit 34), and the model change request stored in the model change request list storage unit 32. A request list is obtained (step S1).

Next, the model change request generation unit 11 determines whether the model change condition defined by the list number to be referenced in the model change request list (see FIG. 3) is established based on the various information about the acquired operation state. It is determined whether or not (step S2).

Note that the list number to be referenced in the determination process of step S2 is updated each time the model change request generation process is performed. For example, when the model change request list shown in FIG. 3 is used, the model change request generation unit 11 sequentially updates the list number to be referred to for each model change request generation process from "1" to "5". , the determination process of step S2 is performed. Therefore, if the model change condition with list number "1" was referred to in the previous model change request generation process, the model change condition with list number "2" is referred to in the current model change request generation process. be. Also, in the previous model change request generation process, if the model change condition with the list number "5" was referred to, in the current model change request generation process, the list number to be referenced is returned to "1", and the list number The model change condition of "1" is referenced.

In step S2, when the model change request generation unit 11 determines that the model change condition to be referenced is not satisfied (NO determination in step S2), the model change request generation unit 11 performs model change request generation processing. exit. In this case, no model change request signal is output from the model change request generator 11 to the model drawing unit 12 .

On the other hand, when the model change request generation unit 11 determines in step S2 that the model change condition to be referenced is satisfied (when step S2 determines YES), the model change request generation unit 11 generates a model change request. Signal generation and output processing are performed (step S3). Note that the model change request signal generated in this process includes information (see FIG. 3) on the change model and change details defined in the list number to be referenced. For example, when the list number being referred to in the example of FIG. is changed to blue”. After the process of step S3, the model change request generation unit 11 terminates the model change request generation process.

In this embodiment, an example was described in which the model change condition referred to in the determination process of step S2 is updated for each model change request generation process, but the present invention is not limited to this. For example, in one judgment process of step S2, it is possible to collectively judge whether all the model change conditions specified in the model change request list are satisfied or not satisfied.

In addition, in the present embodiment, during the operation of the operation state display device 100, the model change request generation process is performed at predetermined time intervals so that the operation state of the elevator, which changes from moment to moment, can be displayed substantially continuously. Although a repeated example has been described, the invention is not limited to this. For example, the model change request generating process may be periodically and repeatedly executed at a time interval longer than the execution interval (the predetermined time interval) of the operation state drawing process performed by the model drawing unit 12 . Further, for example, the above-described model change request generating process may be executed only during a period when a predetermined event (problem) subject to model change is likely to occur. In these cases, the processing load on the calculation unit 1 can be reduced.

Next, operation state drawing processing executed by the model drawing unit 12 (calculation unit 1) will be described with reference to FIG. First, the model drawing unit 12 creates drawing data reflecting the operating state of the elevator (step S11). In this process, the model drawing unit 12 extracts various information about the current elevator operation status stored in the building operation status management unit 31 (elevator operation status storage unit 34) and various elements stored in the element model storage unit 33. Get model data and Next, the model drawing unit 12 creates drawing data of the current operating state of the elevator based on these input data.

Next, the model drawing unit 12 determines whether or not a model change request signal has been input (step S12).

When the model drawing unit 12 determines in step S12 that the model change request signal has not been input (NO in step S12), the model drawing unit 12 ends the operation state drawing process.

On the other hand, when the model drawing unit 12 determines in step S12 that a model change request signal has been input (when step S12 determines YES), the model drawing unit 12 draws an element corresponding to the model change request signal. The display mode of the model is changed (step S13).
