[Embodiment]
[Example of display control processing]
Hereinafter, as an example of the monitoring device, the monitoring device 100 included in the lighting system 1 will be described using an example. FIG. 1 is a diagram illustrating an example of a monitoring device 100 according to the embodiment. In the example shown in FIG. 1, the lighting system 1 includes a plurality of lighting devices 10 (in FIG. 1, shown as lighting devices 10a, 10b, and 10d. When it is not necessary to distinguish the lighting devices 10a, 10b, and 10d, they are collectively referred to as “lighting device 10”). , A plurality of RDM nodes 20 (indicated as RDM nodes 20-1 to RDM nodes 20-n in FIG. 1 and collectively referred to as “RDM nodes 20” if there is no need to distinguish them from each other), hub 30, control console 40 , Having a monitoring device 100. The types and numbers of the lighting devices 10 and the RDM nodes 20 included in the lighting system 1 can be arbitrarily changed.

In the lighting system 1, the lighting device 10 is a lighting device capable of bidirectional communication with the RDM node 20 and the monitoring device 100 by a communication method according to the RDM (Remote Device Management) standard that is an extension of DMX. That is, the illuminating device 10 according to the embodiment is an illuminating device compatible with the RDM standard.

In the present embodiment, description will be given according to the RDM standard, but ACN (Architecture) defined as a standard for a system capable of bidirectional communication (for example, Ethernet (registered trademark) in which ESTA (Entertainment Services and Technology Association) is replaced by DMX). for Control Networks) or sACN (streamingACN)).

Further, the lighting device 10 includes a device having a semiconductor light emitting element such as an LED (Light Emitting Diodes), a device having a motor, etc., and by changing the brightness, range, color, angle, etc. according to a control signal. , Lighting production in the studio and stage. The lighting device 10 is a facility installed in an arbitrary space such as a studio or a stage, and is installed in a baton that is a suspension device that suspends the lighting device. The example of FIG. 1 shows that the lighting devices 10a, 10b, and 10d are installed in the baton L-1.

The RDM node 20 is a distributor that distributes control information capable of two-way communication with the lighting device 10 and the monitoring device 100 by a communication method in accordance with the RDM standard that is an extension of DMX. Specifically, the RDM node 20 is connected to the hub 30 via a wired or wireless network such as Ethernet in a manner capable of bidirectional communication, and communicates with the monitoring device 100 and the like via the hub 30.

Further, in the example of FIG. 1, the RDM node 20 is installed in the baton like the lighting device 10. In the example of FIG. 1, the RDM node 20-1 is installed in the baton L-1, the RDM node 20-2 is installed in the baton L-2, and the RDM node 20-n is installed in the baton L-n. Is installed. In addition, the RDM node 20 acquires information about the baton in which the RDM node 20 is installed and information about the lighting device 10 connected to the RDM node 20 in response to an instruction from the monitoring device 100, and returns the information to the monitoring device 100. The information regarding the baton may be stored in the monitoring device 100 in advance if the RDM node is fixed.

Further, the RDM node 20 has a plurality of ports. In the example of FIG. 1, the RDM node 20-1 has ports 20a to 20d. Each of the ports 20a to 20d is a port to which a port ID for identifying each is given, and is, for example, a connection terminal (connector) for transmitting and receiving a signal to and from the lighting device 10 according to the RDM standard.

Further, in the example of FIG. 1, the positions of the ports 20a to 20d in the baton L-1 are positions P11 to P14. In the present embodiment, the position of each of the ports 20a to 20d is indicated by a conceptual symbol, but in reality, for example, in the case of the port 20a, the baton L-1 is viewed from the "specific direction". The position, for example, "leftmost" is shown. In the case of the port 20b, the position when the baton L-1 is viewed from a specific direction, for example, "second from the left" is shown.

It should be noted that the way of indicating the position of each port with respect to such a baton is merely an example, and any notation may be used. For example, the position of each port may be indicated by coordinates with respect to the baton. Further, each baton has identification information (for example, an identification number, a name, etc.) capable of identifying the baton at a predetermined location, and a direction in which such identification information can be visually recognized (for example, for the baton) The front) corresponds to the “specific direction”.

To summarize the above, in the example of FIG. 1, with respect to the RDM node 20-1 in which the baton L-1 is installed, the lighting device 10a is connected to the port 20a that currently exists at the position P11 and the lighting device 10a exists at the position P12. The lighting device 10b is connected to the port 20b, the lighting device 10 is not connected to the port 20c at the position P13, and the lighting device 10d is connected to the port 20d at the position P14.

Here, the control processing performed by the RDM node 20 will be described. The RDM node 20 sets the control address using the RDM function to the lighting device 10 connected to each port (for example, the ports 20a to 20d) according to an instruction from the control console 40 described later. For example, when the RDM node 20 receives from the control console 40 information regarding a control address newly assigned to the lighting device 10 installed in each port, the RDM node 20 sets the control address newly assigned to the lighting device 10 according to the information. Then, the RDM node 20 temporarily stores the newly assigned control address in association with the port ID of the port to which the lighting device 10 is connected.

The RDM node 20 acquires information about the lighting device 10 connected to the port according to an instruction from the monitoring device 100. For example, the RDM node 20 outputs a request for reading the lighting device information from each of the ports 20a to 20d. Then, when the RDM node 20 receives the lighting device information as a response from the lighting device 10, the RDM node 20 temporarily associates the port ID of the port that received the lighting device information with the newly assigned control address. Remember.

Further, when the RDM node 20 acquires the lighting device information, the RDM node 20 transmits identification information for identifying each device to the monitoring device 100 described below together with the acquired lighting device information, and the monitoring device 100 transmits the information received from the RDM node. Remember. Specifically, the RDM node 20 associates the baton ID, the lighting device ID, the port ID, and the ID of its own device, that is, the node ID with each other, and transmits them together with the lighting device information to the monitoring device 100 described later. This point will be described using the example of FIG. In addition, in the present embodiment, for simplification of description, it is assumed that the symbols given to the baton, the RDM node, the port, and the lighting device correspond to the identification information (ID) of each of these devices.

For example, it is assumed that the lighting device 10a is connected to the port 20a of the RDM node 20-1 installed in the baton L-1. In such a case, the RDM node 20-1 acquires the port ID “20a” and the lighting device ID “10a” from the port 20a according to an instruction from the monitoring device 100. Then, the RDM node 20-1 transmits the baton ID “L-1”, the port ID “20a”, the lighting device ID “10a”, and the own device ID (node ID) “20-1” to the monitoring device 100. .. The RDM node 20-1 also transmits the lighting device information regarding the lighting device 10a together with these IDs. Such lighting device information is, for example, energization time, lighting time of the lighting device 10a, information (e.g., brightness) that digitizes the current brightness, color tone of the lighting, power consumption, failure information, and the like. The RDM node 20-1 also performs the same processing on the ports 20b, 20c, and 20d. The same applies to the RDM node 20-2 and the RDM node 20-n.

The hub 30 is a relay device that is connected to the control console 40 via a wired or wireless network such as Ethernet so as to be capable of bidirectional communication, and relays communication between the control console 40 and each RDM node 20.

Although not shown, the lighting system 1 includes a power supply device that supplies power to the lighting device 10. Such a power supply device has, for example, a function of voltage conversion, a breaker, a detection function of overload or electric leakage, a function of UPS (Uninterruptible Power Supply) and the like.

The control console 40 is a control device capable of communicating bidirectional control information (for example, corresponding to the RDM standard) with the lighting device 10. When the control console 40 receives an operation command for the lighting device 10 from a user (for example, an operator who operates the control console 40), the control console 40 generates control information including a control address given to the lighting device 10, and via the hub 30. Control information is transmitted to the RDM node 20. In this case, the RDM node 20 converts the control information into a control signal according to the RDM standard (for example, a DMX signal) and outputs the control signal to the lighting device 10 indicated by the control address. As a result, the lighting device 10 is controlled. In this way, the lighting device 100 remotely controls each lighting device 10 by using the control address included in the control information compatible with the RDM standard.

The monitoring device 100 monitors the installation status of the lighting device 10 with respect to the baton. For example, the monitoring device 100 receives the ID of each device (batton, port, lighting device, node) from the RDM node 20 as described above because the lighting device 10 supports the RDM standard. It is monitored which lighting device 10 is installed in the baton.

Further, the connection of the lighting device 10 to the port of each RDM node 20 is manually performed by a worker. In order to perform such a manual operation, which lighting device 10 is to be installed in which position of which baton is set, and a preparation drawing raised in the drawing is prepared in advance. Therefore, the worker repeatedly connects the lighting device 10 with reference to the charging plan so as not to install the lighting device in the wrong position. In such a case, it takes time for the worker to check the charging chart many times, resulting in a reduction in work efficiency.

In addition, since a huge number of lighting devices 10 are installed, it may not be noticed even if they are installed in the wrong position with respect to the drawing plan. In such a situation, for example, it is assumed that the lighting device 10 raises a baton in which the lighting device 10 has been installed, and after installing a stage set on the stage, the user notices that the installation position is wrong. In such a case, once the stage set is moved or dismantled and the baton is lowered to correct the installation position, or you risk taking a risk to climb a high stepladder and modify the installation position, resulting in a significant decrease in work efficiency. ..

Therefore, the monitoring device 100 according to the embodiment compares the information about the lighting device 10 based on the captured image of the baton in which the lighting device 10 is installed with the preset information about the lighting device 10. Then, the monitoring device 100 displays the compared comparison result on a predetermined display device. Hereinafter, the display control process performed by the monitoring device 100 will be described in detail.

First, the worker takes an image of the baton that is the work target on which the lighting device 10 is to be installed by using the terminal device having the camera function (step S1). In the following, the installation of the lighting device 10 in the baton and the connection of the lighting device 10 to the port of the RDM node 20 may be treated as synonymous.

The terminal device equipped with the camera function is assumed to be the wearable glass shown in FIG. However, the terminal device is not limited to the wearable glasses, and may be any terminal device having a camera function, a display function, and a communication function using Ethernet. For example, the terminal device may be a smartphone, a tablet terminal, a notebook PC (Personal Computer), a desktop PC, a mobile phone, a PDA (Personal Digital Assistant), or the like.

In the example of FIG. 1, the worker uses the wearable glass GL to photograph the entire baton L-1 so that all the lighting devices 10a, 10b, and 10d installed in the baton L-1 can be inserted. Show. For example, the worker wears the wearable glass GL, that is, actually photographs the baton L-1 through the wearable glass GL to perform the above-described photographing.

Further, FIG. 1 shows an example in which the image captured in this manner is the captured image G1. Here, the points at the time of shooting will be described. One is to shoot so that the entire baton to be operated and all of the lighting devices 10 installed in the baton fit within the captured image. On the other hand, each baton may have identification information (for example, a name, a symbol, a QR code (registered trademark), etc.) capable of identifying the baton in a predetermined location in advance, so that In this case, the worker shoots from a direction in which the identification information is included in the shot image. Such a direction is, for example, a front direction with respect to the baton to be worked. Although not shown, in the example of FIG. 1, it is assumed that the worker has photographed so that the identification character “L-1” written on the surface of the baton L-1 is included.

Next, the wearable glass GL transmits the captured image G1 captured according to the operation of the worker to the monitoring device 100 (step S2). When the monitoring device 100 receives the captured image G1 from the wearable glass GL, the monitoring device 100 analyzes the image of the captured image G1 (step S3). For example, the monitoring apparatus 100 performs image analysis on the captured image G1 to identify the baton L-1 as information about the lighting device 10 in the imaged baton L-1, and at which position the lighting device 10 is located. Identify if is installed. Specifically, the monitoring apparatus 100 identifies the baton identification information and the installation position of the lighting device 10 in the baton by performing image analysis on the captured image G1. At this time, since the monitoring device 100 can also grasp the position of the port in the baton L-1, the port in which the lighting device 10 is connected may be specified in the RDM node 20-1. That is, the monitoring apparatus 100 may recognize the lighting device 10 installed near the port as the lighting device connected to the port.

In the example of FIG. 1, the monitoring device 100 specifies that the baton photographed in step S1 is the baton L-1 by image analysis, and the illumination device 10 is attached to the ports at positions P11, P12, and P14. Identify that is connected. For example, the monitoring apparatus 100 may specify in the position direction such that the position P11 is “leftmost end”, the position P12 is “left 2 (second from right)”, and the position P14 is “rightmost end”. Further, the monitoring device 100 may specify in the coordinate direction such as "X1" as the position P11, "X2" as the position 12 and "X4" as the position P14.

Further, the monitoring device 100 can identify the type of the lighting device 10 installed in the baton, unique identification information, and the installation direction as information about the lighting device 10 by image analysis. For example, the monitoring apparatus 100 analyzes the appearance of the lighting device 10 regarding the type and installation direction of the lighting device such as whether the lighting device 10 installed in the baton L-1 is a spotlight, a horizontal light, or a floodlight. It is possible to specify it.

Further, by monitoring the identification information such as the QR code installed in the lighting device 10, the monitoring device 100 may acquire the identification information unique to the lighting device 10 or the lighting device ID such as an arbitrarily set address. .. In this case, the monitoring device 100 can specify not only the type and installation direction of the lighting device 10 but also the lighting devices 10 one by one.

Next, the monitoring device 100 compares the positional information, which is the positional information specified by the image analysis, on the lighting device 10 with the preset information on the lighting device 10 (step S4). Here, the monitoring device 100 has a device information storage unit 120. The device information storage unit 120 stores a preparation drawing which is a drawing in which which lighting device 10 is installed at which position of which baton is digitized and symbolized. In addition, the digitized and symbolized preparation chart may be referred to as “preparation chart data”.

In the device information storage unit 120 illustrated in FIG. 1, the RDM node “20-1” is installed in the baton “L-1” in the drawing and the port positions in the baton “L-1” are position P11 and position P12. , Position P13, and position P14, indicating that the type of the lighting device 10 to be installed is a spotlight is described in advance in the preparation drawing. Furthermore, the device information storage unit 120 may store the lighting device ID, which is the identification information of each lighting device 10, as the drawing data.

Therefore, the monitoring device 100 is position information specified by image analysis as information about the lighting device 10 based on the captured image G1 and is position information of a port to which the lighting device 10 is connected, and information about the lighting device 10 set in advance. The position information of the port in the baton L-1 derived from the charging diagram is compared with. Then, the monitoring device 100 identifies a non-matching portion by such comparison.

In the example of FIG. 1, the monitoring device 100 specifies that the match at the position P13 cannot be obtained by the comparison process. Specifically, while the monitoring apparatus 100 is designated to connect the lighting device 10 (spotlight) to the port at the position P13 in the baton L-1 on the "preparation diagram data" side, Specifies that the lighting device 10 (spotlight) is not connected to the port at the position P13.

The fact that there is no match in the comparison process in this way indicates that the lighting device 10 is connected incorrectly, or that the lighting device 10 is not connected. Therefore, the monitoring device 100 controls the display so that the worker can confirm the correct installation mode of the lighting device 10 based on the draft image data via the wearable glass GL.

Specifically, the monitoring device 100 identifies that the lighting device 10 (spotlight) is not connected to the port at the position P13, and thus recognizes that the lighting device 10 is connected to the port at the position P13. An animation image G2 is generated. Then, the monitoring device 100 transmits the generated animation image G2 to the wearable glasses GL as a comparison result (step S5). As a result, the monitoring device 100 displays the animation image G2 in a mode in which a worker is instructing to connect a spotlight to the position P13 in the actual baton L-1 that is currently visually recognized through the wearable glass GL. It is displayed (step S6).

As a result, the worker does not have to check the charging diagram many times, and how the lighting device 10 should be installed in the baton to be worked or the position of the already installed lighting device 10 is incorrect. You will be able to check at a glance if there is any. For this reason, the monitoring device 100 according to the embodiment can allow a worker to easily and accurately perform the installation work of the lighting device 10, thereby improving the work efficiency of the installation of the lighting device 10. You can

In addition, in the example of FIG. 1, the monitoring device 100 shows an example in which the lighting device 10 that is an error target or a connection target is animatedly displayed with respect to the baton and the lighting device 10 that the worker actually views. The animation display is not limited to this. For example, the monitoring apparatus 100 may animation-display all of the baton or the lighting device 10 that is the work target.

The “node ID” indicates identification information for identifying the node installed in the baton identified by the corresponding “batton ID”. The “port ID” indicates identification information for identifying the port included in the node identified by the corresponding “baton ID”.

The “port position” is the installation position of the port identified by the corresponding “port ID”, and indicates the installation position in the baton identified by the corresponding “baton ID”. In addition, such an installation position can be understood as an installation position of the lighting device 10 with respect to the baton. As described with reference to FIG. 1, the “port position” is indicated by, for example, the position direction and coordinates based on the left and right. The “lighting device ID” is identification information indicating the lighting device 10 connected to the port identified by the corresponding “port ID”.

The “device type” indicates the type of the lighting device 10 to be connected as the lighting device 10 connected to the port identified by the corresponding “port ID”.

The current control contents such as information, rated power, luminous flux that can be output, and device information such as color temperature are shown.

That is, in the example of FIG. 3, the node 20-1 is installed in the baton L-1, and the node 20-1 has ports 20a to 20d. Further, in the preparation diagram, an example in which the lighting devices 10a to 10d, which are spotlights, are connected to the ports 20a to 20d on the baton L-1 is shown. In addition, an example is shown in which the positions of the ports 20a to 20d in the baton L-1 are positions P11 to P14.

(Regarding the control unit 130)

The connection relationship between the processing units included in the control unit 130 is not limited to the connection relationship illustrated in FIG. 2 and may be another connection relationship.

(About the receiver 131)
The reception unit 131 receives a captured image captured by the terminal device (wearable glasses GL in the example of FIG. 1) used by a user such as a worker. As described with reference to FIG. 1, when the worker installs the lighting device 10 on the baton, the worker takes an image of the baton to be worked by using the terminal device. Further, when the lighting device 10 is already installed in the work target baton, the worker photographs the work target baton including the lighting device 10. Therefore, the receiving unit 131 receives the captured image of the baton or the lighting device 10 from the terminal device that captured the captured image.

In addition, when the lighting device 10 corresponding to the RDM standard is connected to the port of the RDM node 20, the receiving unit 131 outputs the baton ID, the lighting device ID, the port ID, and the node ID from the RDM node 20. Also, the lighting device information (luminance etc.) may be received.

(About the analysis unit 132)
The analysis unit 132 performs image analysis of the captured image captured by the reception unit 131, and specifies information regarding the device included in the captured image. For example, when the captured image includes a baton, the analysis unit 132 specifies the identification information of the baton described in the baton. Further, when the captured image includes the lighting device 10, the analysis unit 132 may specify the position information of the port to which the lighting device 10 is connected. For example, the analysis unit 132 identifies which lighting device 10 is connected to the port at which position based on the positional relationship between the baton and the lighting device 10.

Further, the analysis unit 132 may identify the type and direction of the lighting device 10 installed in the baton by image analysis. A two-dimensional code (QR code) including unique information of the lighting device 10 may be attached to each lighting device 10. In such a case, the analysis unit 132 identifies the lighting device ID of the lighting device 10 by reading the QR code, for example.

For example, the comparison unit 133 compares the position information specified by the analysis unit 132, which is the position information regarding the lighting device 10, and the preset information regarding the lighting device 10. The information regarding the lighting device 10 set in advance is, for example, draft data stored in the device information storage unit 120.

Further, when the type of the lighting device 10 is specified by the analysis unit 132, the comparison unit 133 compares the specified type of the lighting device 10 with the type of the lighting device 10 preset in the charging plan data. To do. In addition, the installation direction of the lighting device 10 may be set in advance in the preparation drawing data. In such a case, the comparison unit 133 compares the installation direction of the lighting device 10 identified by the analysis unit 132 with the installation direction of the lighting device 10 in the charging plan data.

Then, the comparison unit 133 identifies the disagreement between the information about the lighting device 10 based on the captured image and the preset information about the lighting device 10 by the above-described comparison processing. For example, the comparison unit 133 specifies the position information that is specified by the analysis unit 132 and that does not match the position information of the lighting device 10 in the charging plan data among the position information about the lighting device 10. Similarly, with respect to the type and installation direction of the lighting device 10, the comparison unit 133 identifies a mismatch with the charging plan data.

(About display control unit 134)
The display control unit 134 displays, as the comparison result, content indicating that the information regarding the lighting device 10 set in advance does not match. Specifically, the display control unit 134 causes the terminal device that is the transmission source of the captured image to display the comparison result obtained by the comparison by the comparison unit 133. More specifically, the display control unit 134 generates an animation image as content based on the comparison result obtained by the comparison by the comparison unit 133. For example, the display control unit 134 generates an animation image that allows the worker to recognize the comparison result by the comparison unit 133 via the terminal device.

As an example, the display control unit 134 causes the worker to actually recognize the lighting device 10 having an installation error with respect to the baton and the lighting device 10 that are actually viewed through the terminal device, Alternatively, an animation image for instructing to connect the target lighting device 10 to the port determined in the drawing data is generated.

Then, the display control unit 134 transmits, for example, the generated animation image to the terminal device so that the generated animation image is superimposed and displayed on the baton and the lighting device 10 that the worker actually views through the terminal device. ..

In addition, when the lighting device 10 compliant with the RDM standard is installed in the baton, the display control unit 134 uses the fact that the receiving unit 131 receives various kinds of identification information, and the display control unit 134 sets the lighting device 10 for each port. The installation position may be displayed. Specifically, the display control unit 134 displays detailed information such as which lighting device 10 is connected to which port together with the animation image using, for example, identification information.

Now, in the following, an example of the display control process by the monitoring device 100 will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of a display control process performed by the monitoring device 100 according to the embodiment. Note that the description using FIG. 4 is to make FIG. 1 more detailed, and thus the content already described in FIG. 1 will be omitted.

First, in the wearable glass GL, it is assumed that the entire baton L-1 is photographed according to the operation of the worker so that all the lighting devices 10a, 10b, 10d installed in the baton L-1 enter. The image captured in this manner is the captured image G1. Then, the wearable glass GL transmits the captured image G1 to the monitoring device 100.

When the receiving unit 131 receives the captured image G1, the analysis unit 132 of the monitoring device 100 performs image analysis of the received captured image G1. For example, the analysis unit 132 obtains the analysis result R1 as shown in FIG. 4 by image analysis. Specifically, the analysis unit 132 specifies that spotlights are installed as the lighting devices 10 at the ports at the positions P11, P12, and P14 in the baton L-1. In addition, for example, when the identification information (for example, QR code) of the illumination device 10 is attached to each of the illumination devices 10, the analysis unit 132 also includes the illumination device ID specified from the QR code by image analysis. It can be included in the analysis result R1.

Here, it is assumed that a spotlight compatible with the RDM standard is installed in the baton L-1 in advance. In addition, the lighting device 10 currently connected to the ports at the positions P11, P12, and P14 is also a spotlight compliant with the RDM standard. In this way, when the target lighting device 10 is compatible with the RDM standard, the monitoring device 100 not only displays the animation image as described above, but also displays more detailed information about the lighting device 10. Can be displayed. That is, the display control unit 134 causes the baton to display detailed information about the lighting device 10 to be installed based on the information (for example, various IDs and setting modes) received from the lighting device 10 that was photographed together with the baton.

For example, the comparison unit 133 adds more detailed information to the analysis result R1 obtained by the analysis unit 132 by linking with the RDM as a pre-stage of performing the comparison process. For example, the comparison unit 133 associates the “port ID” and the “illumination device ID” with the analysis result R1 as shown in FIG. That is, the comparison unit 133 associates the “port ID” and the “lighting device ID” received by the receiving unit 131 because the lighting device 10 is compatible with the RDM standard, based on the device information storage unit 120 illustrated in FIG. 3. ..

For example, the comparison unit 133 refers to the device information storage unit 120 when the reception unit 131 receives the information indicating that the lighting device 10b is connected to the port 20a, and the port 20a is the port corresponding to the position P11. Identify that there is. Then, the comparison unit 133 adds these pieces of information to the analysis result R1 so that the port ID “20a”, the port position “P11”, and the lighting device ID “10b” are associated with each other. As described above, the detailed information added to the analysis result R1 by the comparison unit 133 is the analysis result R2 shown in FIG.

Then, the comparison unit 133 compares the analysis result R2 with the preparation drawing data stored in the device information storage unit 120 to identify a mismatch between the two.

In the preparation drawing data, it is preset that the lighting device 10a is connected to the port 20a at the position P11. Further, in the preparation drawing data, it is preset that the lighting device 10b is connected to the port 20b at the position P12. However, according to the analysis result R2, at present, the lighting device 10b is connected to the port 20a and the lighting device 10a is connected to the port 20b. Therefore, the comparison unit 133 identifies that the connection between the lighting devices 10a and 10b is incorrect.

In addition, in the preparation drawing data, it is preset that the lighting device 10c is connected to the port 20c located at the position P13. However, according to the analysis result R2, there is currently no connection to the port 20c. Therefore, the comparison unit 133 identifies that the lighting device 10c is not connected to the port 20c.

Then, the display control unit 134 generates an animation image based on the comparison result obtained by the comparison unit 133 as described above, and displays the generated animation image on the wearable glass GL. For example, the display control unit 134 displays information regarding the lighting device 10 to be connected to each port. Specifically, the display control unit 134 is, for example, next to the incorrectly connected lighting devices 10a and 10b so that which specific lighting device 10 is connected to which port is correct. Information about the lighting device 10 (for example, the lighting device ID) is displayed. Further, a comment or a pictorial indicating that the connection is incorrect may be displayed.

The display control unit 134 may also display the device type, the mode, the illumination angle, etc., as shown in FIG. The device type, the mode, and the illumination angle are information set in advance in the preparation drawing.

Further, the display control unit 134 identifies that the lighting device 10c is not connected to the port 20c at the position P13 by the comparison unit 133, and thus the animation image G2 that causes the port 20c to recognize that the lighting device 10c is connected. To generate. Then, the display control unit 134 causes the wearable glasses GL to display the generated animation image G2.

Thereby, even if the detailed setting is made such that the lighting device 10 corresponding to the specific ID is connected to the specific port in the preparation drawing, the worker repeatedly confirms the preparation drawing. Without using the wearable glasses, it is possible to easily visually recognize such settings while performing the work. Therefore, the monitoring device 100 can improve work efficiency.

Note that FIG. 4 shows an example in which the lighting device 10 correctly installed on the baton L-1, specifically, the lighting device 10 connected to the port 20d, is not displayed in animation. However, the display control unit 134 displays, for example, the device type, the lighting device ID, the mode, the angle, and the like so that the worker can reconfirm the installation mode even when the display device is properly installed in this way. May be.

Further, in the example of FIG. 4, in the analysis result R1, there is no display of the lighting device ID installed at each port position, but the lighting device ID of the lighting device 10 installed at each port position is also combined by image analysis. You may make it correspond. In this case, in the process of obtaining the analysis result R2, the monitoring device 100 does not match the correspondence between the port position and the lighting device ID acquired by the RDM and the correspondence between the port position and the lighting device ID in the analysis result R1. Can be identified. In other words, when the device information storage unit 120 stores the lighting device IDs corresponding to the respective lighting devices 10, the monitoring device 100 has the port ID and the lighting device ID correctly connected as shown in the drawing, but the lighting device It is possible to specify that the installation position of the device 10 is incorrect and to display that effect.

[Display control processing flow]
Next, a procedure of processing by the lighting system 1 according to the embodiment will be described with reference to FIG. FIG. 5 is a sequence diagram showing a display control processing procedure by the illumination system 1 including the monitoring device 100 according to the embodiment.

First, the receiving unit 131 of the monitoring device 100 determines whether a captured image has been received from a terminal device (display terminal such as wearable glasses GL) (step S101). When it is determined that the captured image is received (step S101; Yes), the analysis unit 132 analyzes the image of the received captured image (step S102). On the other hand, when the receiving unit 131 determines that the captured image has not been received (step S101; No), the receiving unit 131 waits until the reception.

Next, the comparing unit 133 is the information transmitted from the RDM node 20 included in the captured image when the analysis result is obtained by the image analysis, and the lighting device connected to the port of the RDM node 20. It is determined whether the information about 10 has been received (step S103). For example, when the lighting device 10 complies with the RDM standard, the comparing unit 133 causes the receiving unit 131 to receive the baton ID, the node ID, the port ID, and the lighting device ID transmitted from the RDM node 20 included in the captured image. It is determined whether it has been received.

When the baton ID, the node ID, the port ID, and the lighting device ID are received as the information about the lighting device 10 (step S103; Yes), the comparing unit 133 associates the received identification information with the analysis result (step S103). S104). Next, the comparison unit 133 compares the analysis result after the processing in step S104 with the preparation drawing data stored in the device information storage unit 120 (step S105).

Then, the display control unit 134 generates an animation image based on the comparison result obtained by the comparison unit 133 (step S106). Then, the display control unit 134 transmits the generated animation image to be displayed by the terminal device of the captured image transmission source (step S107).

In addition, when the baton ID, the node ID, the port ID, and the lighting device ID are not received as the information about the lighting device 10 (step S103; No), that is, when the lighting device 10 does not support the RDM standard, the comparing unit 133 analyzes the information. The analysis result obtained by the unit 132 is compared with the preparation drawing data stored in the device information storage unit 120 (step S105).

[Variation of image analysis and comparison processing]
In the example of FIG. 1, an example in which the analysis unit 132 specifies the port at which the lighting device 10 is connected by image analysis is shown. That is, the example in which the analysis unit 132 specifies the installation position of the lighting device 10 in the baton using the position of the port by image analysis has been shown. However, the analysis unit 132 identifies the connection mode of the cable that connects the lighting device 10 and the port by image analysis, and the comparison unit 132 compares the identified connection mode with the draft drawing data to connect the cable. May be detected. That is, the comparison unit 132 may determine whether or not there is an error in the cable connection between the lighting device 10 and the port.

In such a case, in the preparation drawing data, which installation position the lighting device 10 is connected to which port is specified in advance. For example, using the example of FIG. 1, in the purchase plan data, the lighting device 10 at the position P11 is connected to the port 20a corresponding to the position P11, and the lighting device 10 at the position P12 corresponds to the position P12. It is assumed that it is specified in advance to connect to the port 20b which is the port to be used.

Here, the analysis unit 132 analyzes the captured image so that the lighting device 10 at the position P11 is connected to the port (port 20b) corresponding to the position P12, and the lighting device 10 at the position P12 corresponds to the position P11. It is assumed that the connection to the port (port 20a) is specified. That is, it is assumed that the analysis unit 132 specifies that the cables intersect.

In such a case, the comparison unit 132 compares the analysis result identified by the analysis unit 132 as described above with the charging data, and sets the lighting device 10 at the position P11 to the port (port 20a) corresponding to the position P11. It is determined that the lighting device 10 at the position 12 is connected to the port (port 20a) corresponding to the position P11, and the cable connection is incorrect.

In addition, the comparison unit 132 has to connect the lighting device 10 at the position P12 to the port (port 20b) corresponding to the position P12, while the lighting device 10 at the position P11 corresponds to the port (port) corresponding to the position P12. 20b) and it is determined that the cable connection is incorrect. As a result, the display control unit 134 has an incorrect cable connection and generates an animation image instructing the correct connection, and displays the animation image on the wearable glass GL.

If there is an error in the cable connection as described above, an error also occurs in the DMX address that should be originally assigned to each lighting device 10, but the monitoring device 100 according to the embodiment prevents such an error from occurring. can do.

[Variation of display control processing]
In the above embodiment, as shown in FIG. 3, the example in which it is predetermined that the lighting device 10 is connected to all the ports in each baton is shown. However, in the baton, there is a case where a rule is determined that the lighting device 10 is not connected to a specific port. Such rules are also set in advance in the stocking plan.

In this case, if the comparison unit 133 is the information about the lighting device based on the captured image, whether the lighting device 10 is installed on the baton according to the predetermined rule shown in the charging data by comparison with the charging data. Determine whether or not. Then, when it is determined that the display control unit 134 is not installed according to the predetermined rule, the display control unit 134 displays the correct installation mode corresponding to the predetermined rule by animation.

This point will be described with reference to FIG. In the captured image G1 captured by the wearable glass GL, the lighting device 10 is installed at positions P11, P12, and P14 in the baton L-1. Here, although not shown, it is assumed that it is predetermined as a rule that the lighting device 10 is not installed at the position P14 in the preparation drawing data.

In such a case, the comparison unit 133 specifies that the lighting device 10 is not installed according to this rule by comparing the analysis result obtained by analyzing the captured image G1 and the preparation drawing data. Specifically, the comparison unit 133 identifies that the lighting device 10 is installed at the position P14 that should not be originally installed, and outputs such an identification result to the display control unit 134.

The display control unit 134 receives the output from the comparison unit 133 and generates an animation image. For example, the display control unit 134 generates warning information that warns that the user should not connect to the position P14 as an animation image. Then, the display control unit 134 transmits to the wearable glasses GL so that the created animation image is displayed.

Further, in the above-described embodiment, the example in which the analysis unit 132 specifies the baton based on the identification information written in the baton is shown. However, the analysis unit 132 may specify the baton based on the shape of the baton. Further, the display control unit 134 may employ any other method for displaying the comparison result, instead of displaying the comparison result as an animation image. Further, the lighting device 10 is not limited to being compliant with the RDM standard as long as it is capable of bidirectional communication.
