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 change control is performed.

[Calculation unit]
The calculation unit 1 is a configuration unit that controls the display 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 generation unit 11 includes various information regarding the operating state of the elevator stored in the building operation state management unit 31 described later, and a model change request list stored in the model change request list storage unit 32 described later (the figure described later). 3) and are acquired as input data. Next, the model change request generation unit 11 needs to highlight (change) at least a part of the various element models described later displayed on the operation screen 21 described later based on these input data. If so, a model change request signal (instruction) corresponding to the change is generated. Then, the model change request generation unit 11 outputs the generated model request change signal to the model drawing unit 12. The specific content of the model request change signal generation process by the model change request generation unit 11 will be described in detail later.

The model drawing unit 12 includes various information regarding the operating state of the elevator stored in the building operation state management unit 31 described later, and various element models required for the display configuration of the operation screen 21 stored in the element model storage unit 33 described later. The data (see FIG. 4 described later) is acquired as input data. Then, based on these input data, the model drawing unit 12 generates drawing (display) data of the operation screen 21 showing the operating state of the elevator that changes from moment to moment, and outputs the drawing (display) data to the display unit 2.

Further, when a predetermined event (problem) such as congestion occurs in the model drawing unit 12 in the operating state of the elevator, the event is caused by the model change request generation unit 11 to the model drawing unit 12 in addition to the above-mentioned various data. The model request change signal corresponding to is input. Then, when the model request signal is input, the model drawing unit 12 changes the display mode of the element model related to the occurrence (occurrence location) of a 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 time (when the problem does not occur) according to the content of the input model request change signal. The data is changed to display mode data that can be displayed, and the drawing data of the changed operation screen 21 is generated. When the model request change signal is not input, the model drawing unit 12 generates drawing data indicating the current operation state in the display mode of the element model at the normal time without displaying the change of the element model. Then, it is output to the display unit 2.

[Display]
The display unit 2 has an operation screen 21, and displays the operation state (operation status) of the elevator on the operation screen 21 based on the drawing data input from the model drawing unit 12. The display mode of the operating status 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 unit The building operation status management unit 31 stores (manages) various information indicating the operation status of each facility (elevator, etc.) in the building. In the present embodiment, the building operation state management unit 31 includes at least an elevator operation state storage unit 34 in which various information (first information) indicating the operation state of the elevator is stored.

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

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

Various information indicating the operating state of the elevator stored in the elevator operating state storage unit 34 is appropriately changed according to the use of the operating state display device 100 of the present embodiment.

For example, when the operation status 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 is used as various information indicating the operation status of the elevator. May be used. Further, when the operation status display device 100 is used as a simulator, various data related to the operation status acquired at the time of actual operation in the past may be used as various information indicating the operation status of the elevator.

On the other hand, for example, when the operation status display device 100 of the present embodiment is used at the site (actual machine operation), various real-time information is stored in the elevator operation status storage unit 34 as various information indicating the operation status of the elevator. It may be configured. Further, even when the operation status display device 100 is used in the field, for example, when it is used for the purpose of analyzing the past operation status, improving the operation, etc., the operation in the past (for example, for the past several days) Various information regarding 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. In this model change request list, each list number (No. "1" to "5") defines a data set in which the model change condition (third information) and the content of the model change request are combined into one set. Will be done. The model change condition can be arbitrarily set as long as it can be detected (determined whether the condition is satisfied or not) 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 event (problem) that the waiting time of the elevator increases. The model change request list may be created separately for each type of event that may occur, or the model change request list for all event types may be combined into one list. For example, as an event (problem) other than an increase in the waiting time of the elevator, for example, an event such as an increase in power consumption can be mentioned. When a plurality of elevators are installed in the building, a model change request list may be created for each elevator, or a model change request list for all elevators may be combined into one list.

In the "model change condition" column in the model change request list shown in FIG. 3, conditions (events) that are candidates for causing an increase in the waiting time of the elevator are defined. Further, in the "model change request" column in FIG. 3, the element model to be changed ("change model" column) and the change content of the display mode of the element model ("change content" column) are associated with each other. Stipulated (with a string).

In the present embodiment, for example, a car model, a door model, a floor model, a human model, a hoistway model, and the like are prepared as element models. The car model is a model representing the elevator car displayed on the operation screen 21, and the door model is a model representing the elevator doors provided in the elevator halls on each floor displayed on the operation screen 21. is there. 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 existing 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 of list number "1", the "elevator hoistway model" and "model color are lighter" as the changed model and the changed contents for the model change condition that "the running time of the elevator is longer than the traffic calculation value", respectively. "Change to red" is associated. Therefore, when the model change condition of the list number "1" is satisfied, the color of the elevator hoistway model changes to light red on the operation screen 21.

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

In the data set of list number "3", for the model change condition that "the elevator boarding / alighting time is longer than the traffic calculation value", the changed model and the changed contents are "elevator door model and car model" and "model color", respectively. Is changed to light red "is associated. Therefore, when the model change condition of the list number "3" is satisfied, the colors of the elevator door model and the car model both change to light red on the operation screen 21. In this example, the color of both the door model and the car model is changed when the elevator boarding / alighting time is longer than the calculated traffic value, but the present invention is not limited to this. If the elevator boarding / alighting time is longer than the calculated traffic 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 of the list numbers "1" to "3" is the running calculated based on a predetermined formula when information such as the capacity of the elevator and the rated speed is given. Time, door opening time (door opening time), boarding / alighting time, 5 minutes Approximate value of the number of people transported. By detecting the occurrence of a discrepancy between these traffic calculation values and the information acquired from the building operation status management unit 31 (information regarding the predetermined operation status of the elevator), the cause of the increase in the waiting time of the elevator is identified. Can be done.

In the data set of list number "4", in response to the model change condition that "the elevator has not been moving for a long time", the changed model and the changed contents are "elevator car model" and "change model color to blue", respectively. Is associated. Therefore, when the model change condition of the list number "4" is satisfied, the color of the elevator car model changes to blue on the operation screen 21. The establishment / non-establishment of the model change condition specified in the list number "4" is determined by comparing the time when 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 elevator cannot be operated efficiently due to, for example, a setting error in managing the elevator group.

Further, in the data set of the list number "5", a model change condition that "a plurality of elevators exist within a certain range" is defined. Then, in the data set of the list number "5", for this model change condition, the changed model and the changed contents are "elevator hoistway model existing within the range" and "elevator existing range is changed to light yellow", respectively. "Is associated. Therefore, when the model change condition of the list number "5" is satisfied, the color of the hoistway model in a certain range (predetermined range) in which a plurality of elevators exist on the operation screen 21 changes to light yellow.

It is known that when a plurality of elevators move in the same position (height position) at the same time in the moving direction, the service is biased, which tends to increase the waiting time. Therefore, the model change condition of the list number "5" can be used to detect this event (phenomenon). The data set of list number "5" is specified when multiple elevators (hoistways) are provided in the building, but when the number of elevators in the building is one, the list is listed. The dataset with number "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 the list numbers "1" to "5" is satisfied at a certain time (when the waiting time of the elevator increases), the model change request generation unit 11 Outputs a model change request to the model drawing unit 12. At this time, the output model change request signal includes information on the change model and the change contents associated with the established model change condition (list number). Next, the model drawing unit 12 changes the drawing data of the model to be changed based on the information on the changed model and the changed contents included in the input model change request signal. As a result, when at least one of the model change conditions of the list numbers "1" to "5" is satisfied at a certain time, the display mode of the element model to be changed is displayed on the model drawing unit 12 on the operation screen 21. The display mode changes according to the content of the input model change request signal. As a result, the occurrence of an event that is a candidate for the cause of the increase in the waiting time of the elevator can be reflected (highlighted) on the operation screen 21.

In the example shown in FIG. 3, an example in which a traffic calculation value is used as a threshold value for determining whether or not the model change conditions specified by the list numbers "1" to "3" are satisfied has been described, but the present invention has been described. The present invention is not limited to this, and an arbitrary threshold value can be set as needed. For example, a predetermined predetermined value may be used instead of the calculated traffic value.

Further, in the example shown in FIG. 3, an example in which a candidate cause of a problem (event) occurs is described as a model change condition in the model change request list, but the present invention is not limited to this. Any condition when it is necessary to change the display mode of the element model due to factors other than the occurrence of the problem may be set as the model change condition. For example, in the model change request list, various conditions at the time of solving the problem may be used as the model change condition. In this case, if the predetermined problem solving condition is satisfied, the model change request signal is output from the model change request generation unit 11 to the model drawing unit 12. Then, the model drawing unit 12 changes (returns) the display mode of the corresponding element model from the display mode when the problem occurs to the display mode when the problem does not occur (normal time) based on the model change request signal. ..

Further, in the example shown in FIG. 3, an example of changing the color of the element model to be changed is described for changing the display mode of the element model, but the present invention is not limited to this and emphasizes the change of the element model. Any modification can be applied as long as it can be displayed. For example, the element model to be changed is blinked, the shape and / or size of the element model to be changed is changed, some characters or symbols indicating the occurrence of an event are displayed on or near the element model, and the like. Modifications may be applied. Further, for example, these modification modes, modification modes of the present embodiment (change of model color), and the like may be appropriately combined.

The content (type, etc.) of the model change condition 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, at least some of the model change conditions specified in the model change request list (for example, the model change conditions of the list number "5" in FIG. 3) are not related to the equipment, structure, etc. in the building to which they are applied. It may be configured to be common.

Further, in the example shown in FIG. 3, since light red, blue, or light yellow is set as the color after the change of the element model, the color before the change of the element model (normal time) is after these changes. Any color other than the color of can be set.

(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 component model: element) necessary for the configuration of the operation screen 21. .. In the present embodiment, as described above, for example, a car model, a door model, a floor model, a human model, a hoistway model, and the like 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.

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

[Display example of operation screen]
FIG. 4 shows an example of the operation screen 21 displayed by the operation status display device 100 of the elevator of the present embodiment. Note that FIG. 4 is a configuration example of the operation screen 21 displaying the operation state of the elevator in the normal state (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 the third floor.

The operation screen 21 of this example is a car model 40 of each elevator, an elevator door model 41 and a floor model 42 in the elevator hall of each floor, and a person model 43 representing a user existing in the car and on the elevator hall. It is composed. In the example of the operation screen 21 shown in FIG. 4, the hoistway model of each elevator is not shown for convenience of explanation.

The operation screen 21 of this example shows a state in which the elevator has not arrived on 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 at a position between the first floor and the second floor, and two passengers exist in the car of the elevator E2.

Further, the operation screen 21 of this example shows a state in which the elevator E1 arrives on the second floor and only the door of the elevator E1 is opened 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 (stands by) in front of the door of the elevator E1, and one passenger exists in the car of the elevator E1. The state is shown.

Further, in the operation screen 21 of this example, the elevator E3 arrives at the third floor, and only the door of the elevator E3 is opened in the elevator hall on the third floor. Further, in the operation screen 21 of this example, in the elevator hall on the third floor, there are two users (standby) in front of the door of the elevator E3, and one passenger in the car of the elevator E3. The state is shown.

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

First, the model change request generation process executed by the model change request generation unit 11 (calculation unit 1) will be described with reference to FIG. First, the model change request generation unit 11 contains various information regarding the operation status of the elevator stored in the building operation status management unit 31 (elevator operation status storage unit 34) and the model change stored in the model change request list storage unit 32. Acquire the request list (step S1).

Next, the model change request generation unit 11 determines whether the model change condition specified in the reference list number in the model change request list (see FIG. 3) is satisfied based on the acquired various information regarding the operating state. Whether or not it is determined (step S2).

The list number to be referred to in the determination process in step S2 is updated for each model change request generation process. 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 numbers to be referred to for each model change request generation process in the order of “1” to “5”. , The determination process of step S2 is performed. Therefore, when the model change condition of the list number "1" is referred to in the previous model change request generation process, the model change condition of the list number "2" is referred to in the current model change request generation process. Model. Further, when the model change condition of the list number "5" is referred to in the previous model change request generation process, the reference list number is returned to "1" in the current model change request generation process, and the list number is used. The model change condition of "1" is referred to.

In step S2, when the model change request generation unit 11 determines that the model change condition to be referred to is not satisfied (NO determination in step S2), the model change request generation unit 11 performs the model change request generation process. To finish. In this case, the model change request signal is not output from the model change request generation unit 11 to the model drawing unit 12.

On the other hand, in step S2, when the model change request generation unit 11 determines that the model change condition to be referred to is satisfied (when the determination in step S2 is YES), the model change request generation unit 11 determines the model change request. Signal generation and output processing are performed (step S3). The model change request signal generated by this process includes information on the change model and change contents specified in the reference list number (see FIG. 3). For example, when the list number being referenced in the example of FIG. 3 is "3", the model change request signal contains information indicating that the changed model is a "car model" and the changed content is "model color". Contains information indicating that "changes to blue". Then, after the process of step S3, the model change request generation unit 11 ends the model change request generation process.

In the present embodiment, an example in which the model change condition referred to in the determination process in step S2 is updated for each model change request generation process has been described, but the present invention is not limited to this. For example, in the determination process of step S2 once, the establishment / non-establishment of all the model change conditions defined in the model change request list may be collectively determined.

Further, in the present embodiment, the model change request generation process is performed at predetermined time intervals so that the operating state of the elevator, which changes from moment to moment, can be displayed substantially continuously while the operation status display device 100 is operating. Although repeated examples have been described, the present invention is not limited thereto. For example, the model change request generation process may be periodically repeated 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 model change request generation process described above may be executed only in a time zone in which a predetermined event (problem) that is the target of the model change is likely to occur. In these cases, the processing load on the calculation unit 1 can be reduced.

Get the model data. 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 the model change request signal has been input (step S12).

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

On the other hand, in step S12, when the model drawing unit 12 determines that the model change request signal is input (when the determination in step S12 is YES), the model drawing unit 12 is an element corresponding to the model change request signal. The display mode of the model is changed (step S13). Specifically, the model drawing unit 12 changes the drawing data of the element model to be changed to drawing data that reflects the changed contents. By this processing, the display mode (color in the present embodiment) of the element model related to the event (problem) that has occurred changes to the display mode according to the model change request signal on the operation screen 21. Then, after the process of step S13, the model drawing unit 12 ends the operation state drawing process.

In the operation status display device 100 of the present embodiment, the operating status of the elevator that changes from moment to moment is changed by repeating a series of processes of the model change request generation process and the operation status drawing process at predetermined time intervals as described above. It can be visualized almost continuously. At this time, when a predetermined event occurs, the display mode of the element model that causes the occurrence of the event can be highlighted (changed).
