[0012] Hereinafter, the embodiments will be described in detail with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component placement and connection forms, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present invention. Furthermore, among the components in the following embodiments, components not recited in independent claims will be described as optional components.

[0013] It should be noted that the drawings are schematic diagrams and are not necessarily strict illustrations. In addition, in the drawings, substantially the same components are denoted by the same reference numerals, and overlapping descriptions may be omitted or simplified.

[0014] (Embodiment) [composition] First, the configuration of a lighting production system according to an embodiment will be described below. Fig. 1 is a block diagram showing the functional configuration of a lighting production system according to an embodiment.

[0015] The lighting performance system 10 is a system that can perform lighting performances using multiple lighting fixtures 50 in a target area. The performances here include lighting performances in parks and the like, and lighting performances of buildings such as shrines, temples, museums, suspension bridges, stadiums, and skyscrapers. If the lighting fixtures 50 have a function for projecting images, the performances also include projection mapping onto buildings. In other words, the performances are, for example, performances that use at least one of lighting and images.

[0016] As shown in Fig. 1, lighting performance system 10 specifically comprises an information terminal 20, a performance control panel 30, indicator lights 37, a converter panel 40, and a plurality of lighting fixtures 50. The configuration of each of these devices will be described below. Note that in Fig. 1, thick lines connecting devices represent communication lines based on Ethernet (registered trademark), and thin lines connecting devices represent communication lines based on a communication standard other than Ethernet (registered trademark).

[0017] The information terminal 20 is used by a manager of the lighting performance system 10 or the like to monitor the status of the plurality of lighting fixtures 50. The information terminal 20 is, for example, a personal computer, but may also be a smartphone or a tablet terminal. Specifically, the information terminal 20 includes a reception unit 21, a display unit 22, an information processing unit 23, a storage unit 24, and a first communication unit 25.

[0018] The reception unit 21 receives a user's operation (manual operation). The reception unit 21 is realized by, for example, a touch panel, but may also be realized by a mouse and keyboard.

[0019] The display unit 22 displays an image and is realized by a display panel such as a liquid crystal panel or an organic EL (Electro Luminescence) panel.

[0020] Information processing unit 23 processes information related to, for example, monitoring the status of multiple lighting fixtures 50. Information processing unit 23 is realized, for example, by a microcomputer, but may also be realized by a processor. Information processing unit 23 includes, as functional components, a first determination unit 26 and a first output unit 27. The functions of first determination unit 26 and first output unit 27 are realized, for example, by the microcomputer or processor constituting information processing unit 23 executing a computer program stored in storage unit 24.

[0021] The storage unit 24 is a storage device that stores the computer program executed by the information processing unit 23 and various information necessary for the information processing unit 23 to perform the above-mentioned information processing. The storage unit 24 is realized by, for example, a semiconductor memory.

[0022] First communication unit 25 is a communication module (communication circuit) that enables information terminal 20 to communicate with performance control panel 30. The communication performed by first communication unit 25 is, for example, wired communication based on Ethernet (registered trademark).

[0023] The performance control panel 30 is constructed by electrically connecting multiple devices included in the performance control panel 30 and mounting the multiple devices on a rack. The multiple devices included in the performance control panel 30 include a first switching hub 31, a performance controller 32, a relay device 33, a PLC (Programmable Logic Controller) 34, a second switching hub 35, a touch panel monitor 36, and a signal converter 38.

[0024] The first switching hub 31 is connected to the information terminal 20, the performance controller 32, and the relay device 33.

[0025] The performance controller 32 performs a lighting performance by controlling the plurality of lighting fixtures 50. The performance controller 32 controls the plurality of lighting fixtures 50 by transmitting control signals to the plurality of lighting fixtures 50 via, for example, the first switching hub 31, the signal converter 38, and the conversion panel 40.

[0026] Relay device 33 performs processing for monitoring devices (hereinafter also referred to as network-related devices) directly or indirectly connected to first switching hub 31, such as information terminal 20, performance controller 32, and conversion board 40. Relay device 33 transmits, for example, a response request for alive monitoring to information terminal 20, performance controller 32, and conversion board 40, receives device information that is a response to the response request, and transmits a contact signal indicating the reception result of the device information to PLC 34.

[0027] The PLC 34 monitors devices directly or indirectly connected to the first switching hub 31 based on the contact signal (reception result of device information) obtained from the relay device 33. The PLC 34 includes a second communication unit 34a, an information processing unit 34b, and a storage unit 34c.

[0028] The second communication unit 34a is a communication module (communication circuit) that enables the PLC 34 to communicate with the information terminal 20, the performance controller 32, and the relay device 33. The second communication unit 34a performs wired communication based on Ethernet (registered trademark) with the information terminal 20 and the performance controller 32 via the second switching hub 35. The second communication unit 34a performs communication with the performance controller 32 and the relay device 33 using contact signals. A contact signal refers to a signal obtained by turning on and off a mechanical relay that mechanically opens and closes a contact, and the second communication unit 34a receives contact signals from, for example, the performance controller 32 and the relay device 33.

[0029] The information processing unit 34b processes information related to the monitoring of network-related devices. The information processing unit 34b is realized, for example, by a processor. The information processing unit 34b includes, as functional components, a second determination unit 34d and a second output unit 34e. The functions of the second determination unit 34d and the second output unit 34e are realized, for example, by a microcomputer or processor constituting the information processing unit 34b executing a computer program stored in the storage unit 34c.

[0030] The storage unit 34c is a storage device that stores the computer program executed by the information processing unit 34b, various information necessary for the information processing unit 34b to perform the above-mentioned information processing, etc. The storage unit 34c is realized by, for example, a semiconductor memory.

[0031] The second switching hub 35 is connected to the information terminal 20, the performance controller 32, and the relay device 33.

[0032] The touch panel monitor 36 is a display device on which a display screen (image) is displayed by the PCL 34 (information processing unit 34b). The touch panel monitor 36 is realized by, for example, a touch panel and a display panel.

[0033] The signal converter 38 converts an electrical signal in a format based on Ethernet (registered trademark) into an optical signal. The signal converter 38 is realized by, for example, an SFP (Small Form-factor Pluggable) module connected to the first switching hub 31.

[0034] The indicator light 37 is a warning light (lamp) whose turning on and off is controlled by the PCL 34 (information processing unit 34b) of the performance control panel 30. The indicator light 37 may also be called a patrol lamp or the like. The indicator light 37 is realized by an LED or the like.

[0035] The conversion board 40 converts the optical signal received from the signal converter 38 into an electrical signal and transmits the electrical signal to the lighting fixtures 50 connected to the conversion board 40. The electrical signal here is, for example, a control signal in a lighting control format such as DMX. The conversion board 40 is installed, for example, in the target area. If the total number of lighting fixtures 50 is large, the lighting production system 10 may be equipped with multiple conversion boards 40.

[0036] The lighting fixture 50 is installed in the target area and emits light based on a control signal received from the conversion panel 40. Specifically, the lighting fixture 50 includes a red light source, a green light source, and a blue light source. Each of the red light source, green light source, and blue light source is realized by an LED chip or the like, and the light emission brightness of each light source can be controlled independently. This allows the light emission color of the lighting fixture 50 to be changed. In other words, the lighting fixture 50 has a dimming function and a color adjustment function. Note that each of the red light source, green light source, and blue light source may be realized by a light-emitting module using a semiconductor light-emitting element such as a semiconductor laser, or a solid-state light-emitting element such as an organic or inorganic electroluminescent element.

[0037] [Lighting fixture monitoring operation] In lighting performance system 10, information terminal 20 monitors (determines) whether multiple lighting fixtures 50 are normal or abnormal, and can display the monitoring results on display unit 22. Figure 2 shows an example of a display screen showing the monitoring results of multiple lighting fixtures 50, displayed on display unit 22.

[0038] 2 shows an arrangement of multiple lighting fixtures 50 viewed generally from above, and each small rectangular object in FIG. 2 represents one lighting fixture 50. In the example of FIG. 2, if an object is white, the lighting fixture 50 corresponding to that object is normal, and if the object is black, the lighting fixture 50 corresponding to that object is abnormal.

[0039] The following describes the monitoring operation of multiple lighting fixtures 50 that is performed to display the monitoring result display screen as shown in Figure 2. Figure 3 is a sequence diagram of the monitoring operation of multiple lighting fixtures 50.

[0040] The information processing unit 23 of the information terminal 20 generates an fixture definition file based on a predetermined operation on the reception unit 21 by an administrator or the like, and stores the file in the storage unit 24 (S11). Fig. 4 is a diagram showing an example of the fixture definition file. The fixture definition file is an example of lighting fixture related information.

[0041] As shown in Fig. 4, the fixture definition file includes a location name, a fixture display name, a fixture name, and a position (e.g., 001) on the display screen of Fig. 2. The location name means the name of the installation location of the lighting fixture 50, the fixture display name means the name of the lighting fixture 50 displayed on the display screen of the lighting fixture 50, and the fixture name means the name of the lighting fixture 50 stored (set) in the memory unit of the lighting fixture 50, and will hereinafter also be referred to as the lighting fixture name.

[0042] Next, the information processing unit 23 communicates with the plurality of lighting fixtures 50 using the first communication unit 25 to acquire fixture information from each of the plurality of lighting fixtures 50 (S12). More specifically, communication between the information processing unit 23 (information terminal 20) and the plurality of lighting fixtures 50 is performed via the first switching hub 31, the signal converter 38, and the converter panel 40. This communication is, for example, RDM (Remote Device Management) communication, but other communication methods may also be used. FIG. 5 shows an example of the fixture information of the plurality of lighting fixtures 50 acquired in step S12.

[0043] 5, the fixture information includes the fixture name, UID (Unique ID), manufacturer name, product number, lighting time, etc. This fixture information is stored (set) in advance in the storage unit of lighting fixture 50.

[0044] Next, the information processing unit 23 generates reference information by linking the fixture definition file stored in step S11 with the fixture information acquired in step S12 based on the fixture name commonly included in both the fixture definition file and the fixture information, and stores the reference information in the storage unit 24 (S13). The reference information includes the location name, fixture display name, fixture name, position on the display screen, UID, manufacturer name, product number, and lighting time of each of the multiple lighting fixtures 50.

[0045] In this way, the reference information is information based on the pre-stored instrument definition file and the instrument information acquired in step S12, and in the reference information, the instrument definition file and the instrument information are linked based on the instrument name contained in the instrument definition file and the instrument name contained in the instrument information.

[0046] Thereafter, when a predetermined monitoring timing arrives, information processing unit 23 acquires device information from each of the plurality of lighting fixtures 50 by communicating with the plurality of lighting fixtures 50 using first communication unit 25 (S14). The processing of step S14 is substantially the same as the processing of step S12. The monitoring timing is set, for example, about twice a day, such as before and after a lighting performance using the plurality of lighting fixtures 50. The monitoring timing is set, for example, by an administrator or the like operating reception unit 21.

[0047] The first determination unit 26 determines whether or not there is an abnormality based on the reference information stored in the storage unit 24 in step S13 and the appliance information acquired in step S14 (S15).

[0048] For example, if device information containing the same device name as the device name included in the reference information is acquired in step S14, the first determination unit 26 determines that the lighting device 50 corresponding to the device information is normal. On the other hand, if device information containing the same device name as the device name included in the reference information is not acquired in step S14, the first determination unit 26 determines that the lighting device 50 corresponding to the device information is abnormal. That is, the first determination unit 26 determines the state of the lighting device 50 based on whether or not there is device information whose device name matches the reference information. Examples of abnormalities in a lighting device 50 include a case where the lighting device 50 is unable to communicate with the information terminal 20, and a case where the lighting device 50 is able to communicate with the information terminal 20 but does not respond to the information terminal 20.

[0049] The fixture name stored (set) in the memory unit of lighting fixture 50 can be changed, and changing the fixture name of lighting fixture 50 can cause erroneous determination. Therefore, first determination unit 26 may make a determination based on a unique (unchangeable) UID instead of the fixture name.

[0050] In this case, if device information containing the same UID as the UID included in the reference information is acquired in step S14, the first determination unit 26 determines that the lighting device 50 corresponding to the device information is normal. On the other hand, if device information containing the same UID as the UID included in the reference information is not acquired in step S14, the first determination unit 26 determines that the lighting device 50 corresponding to the device information is abnormal. In other words, the first determination unit 26 determines the state of the lighting device 50 based on whether or not there is device information whose UID matches that of the reference information.

[0051] Next, first output unit 27 generates first determination result information indicating the determination result for each of the plurality of lighting fixtures 50, and outputs the generated first determination result information to display unit 22 (S16). As a result, the monitoring result display screen of Fig. 2 is displayed on display unit 22 (S17).

[0052] The monitoring result display screen in FIG. 2 displays a rectangular object representing a lighting fixture 50. If the object is white, the lighting fixture 50 corresponding to the object is normal, and if the object is black, the lighting fixture 50 corresponding to the object is abnormal. Note that this manner of displaying the object is just an example, and it is not necessary to represent the normal state and the abnormal state by the color of the object. First output unit 27 may display the object on display unit 22 in different manners depending on whether the lighting fixture 50 is determined to be normal or abnormal. For example, first output unit 27 may represent the normal state and the abnormal state by blinking or steadily emitting light from the object, by the shape (outline) of the object, or by the size of the object.

[0053] Furthermore, if an object is present on the display screen but no lighting device 50 corresponding to the object exists in the reference information, the object may be treated as being in a third state that is different from both the normal state and the abnormal state. Specifically, the object in the third state may be displayed in a display mode that is different from both the normal state and the abnormal state.

[0054] In addition, if device information is received that does not include the device name (or UID) in the reference information (if an unknown lighting device 50 is discovered), a message to that effect may be displayed on the monitoring result display screen.

[0055] As described above, information terminal 20 can determine the state of lighting device 50 and output first determination result information (first information regarding the result of the determination) by comparing reference information based on device information (first device information) received from lighting device 50 at a first point in time (at the time of step S12) with device information (second device information) received from lighting device 50 at a second point in time after the first point in time (at the time of step S14).

[0056] [Modification of lighting fixture monitoring operation] The monitoring result display screen in Fig. 2 is an example, and display unit 22 may display a list of monitoring results (determination results) for multiple lighting fixtures 50. Fig. 6 shows another example of such a display screen for monitoring results for multiple lighting fixtures 50.

[0057] The display screen of the monitoring results may be displayed on the touch panel monitor 36. In this case, the first output unit 27 uses the first communication unit 25 to output information for displaying the determination result in step S15 on the touch panel monitor 36 (display device) to the PLC 34. The information is received by the PLC 34 via, for example, the second switching hub 35, and the PLC 34 displays a display screen of the monitoring results (a display screen that is the same as or similar to that in FIG. 2 or FIG. 6) on the touch panel monitor 36 based on the received information. This allows the information terminal 20 to display the monitoring results (determination results) on the touch panel monitor 36 in addition to the display unit 22.

[0058] Furthermore, when it is determined that at least one of the plurality of lighting fixtures 50 is in an abnormal state, first output unit 27 may use first communication unit 25 to output information for displaying the determination result on indicator light 37 (activating indicator light 37). The information is received by PLC 34, for example, via second switching hub 35, and PLC 34 activates indicator light 37 based on the received information. This allows information terminal 20 to notify users located around performance control panel 30 that at least one of the plurality of lighting fixtures 50 is in an abnormal state.

[0059] Meanwhile, an administrator or the like can stop the monitoring operation of multiple lighting fixtures 50 by enabling the maintenance mode of lighting production system 10. Stopping the monitoring operation means stopping the output of the first judgment result information by stopping the judgment by first judgment unit 26, or stopping the output of the first judgment result information by first output unit 27 while continuing to make a judgment by first judgment unit 26.

[0060] The maintenance mode is enabled by a predetermined input (operation) by an administrator or the like to the touch panel monitor 36. Fig. 7 is a diagram showing an example of a display screen displayed on the touch panel monitor 36.

[0061] The predetermined input for enabling the maintenance mode is to select an object containing the characters "Perform maintenance" in (a) of Fig. 7. When such an object is selected, the object changes to an object containing the characters "Cancel maintenance" and for canceling maintenance mode and returning to normal mode, as shown in (b) of Fig. 7.

[0062] By enabling the maintenance mode, an administrator or the like can stop the monitoring operation of the plurality of lighting fixtures 50 and perform maintenance on the plurality of lighting fixtures 50.

[0063] [Network device monitoring] In the lighting performance system 10, the relay device 33 and the PLC 34 can monitor network-related devices such as the information terminal 20, the performance controller 32, and the converter board 40. The monitoring operation of the network-related devices will be described below. Fig. 8 is a sequence diagram of the monitoring operation of the network-related devices.

[0064] The information processing unit 34b of the PLC 34 generates reference information based on a predetermined operation on the touch panel monitor 36 by an administrator or the like, and stores the generated reference information in the storage unit 34c (S21). The reference information includes the ID of each network-related device.

[0065] Thereafter, when a predetermined monitoring timing arrives, the relay device 33 communicates with the network-related devices to acquire device information from each of the network-related devices (S22). More specifically, communication between the relay device 33 and the network-related devices is performed via the first switching hub 31. No device information is acquired from network-related devices that did not respond to the communication of the relay device 33 in step S22.

[0066] The monitoring timing is, for example, once every few seconds, and the network-related devices are monitored more frequently than the lighting fixtures 50. The monitoring timing is set, for example, by an administrator or the like operating the touch panel monitor 36.

[0067] The relay device 33 outputs a contact signal indicating the ID included in the device information to the PLC 34 (S23), and the second communication unit 34a receives the contact signal.

[0068] The second determination unit 34d determines whether or not an abnormality exists based on the reference information stored in the storage unit 34c in step S21 and the contact signal acquired in step S23 (S24).

[0069] For example, if a contact signal indicating an ID identical to an ID included in the reference information is acquired in step S23, the second determination unit 34d determines that the network-related device corresponding to that ID is normal. On the other hand, if a contact signal indicating an ID identical to an ID included in the reference information is not acquired in step S23, the second determination unit 34d determines that the network-related device corresponding to that ID is abnormal. In other words, the second determination unit 34d determines the state of the network-related device based on the presence or absence of a contact signal indicating an ID that matches the reference information.

[0070] Next, the second output unit 34e generates second judgment result information indicating the judgment result for each network-related device, and transmits (outputs) the generated second judgment result information to the information terminal 20 using the second communication unit 34a (S25).

[0071] The first communication unit 25 of the information terminal 20 receives the second determination result information. The information processing unit 23 displays a display screen of the monitoring results on the display unit 22 based on the received second determination result information (S26). Fig. 9 is a diagram showing an example of a display screen of the monitoring results of network-related devices. In the example of Fig. 9, the monitoring results (determination results) of the network-related devices are displayed in a list.

[0072] As described above, the PLC 34 can determine the state of the network-related device based on communication between the second communication unit 34a and the relay device 33 connected to the network-related device, and output second information (second determination result information) regarding the result of the determination.

[0073] [Modification of network-related device monitoring operation] In addition, when the PLC 34 is directly connected to the first switching hub 31, the second communication unit 34a can also acquire device information without going through the relay device 33. In other words, the second communication unit 34a only needs to communicate with the network-related device itself or the relay device 33 connected to the network-related device, and the second determination unit 34d only needs to determine the state of the network-related device based on the communication.

[0074] Furthermore, it is not essential that the relay device 33 transmit a contact signal to the PLC 34, and an electrical signal other than the contact signal may be transmitted.

[0075] Furthermore, the state of the network-related device may be determined by the information terminal 20. That is, the processes of steps S21 to S25 may be performed by the information terminal 20. In this case, the information terminal 20 includes components corresponding to the second communication unit 34a, the second determination unit 34d, and the second output unit 34e.

[0076] Furthermore, the display screen of the monitoring results of the network-related devices may be displayed on the touch panel monitor 36. In this case, the second output unit 34e outputs information for displaying the determination result in step S24 on the touch panel monitor 36 (display device) to the touch panel monitor 36. This allows the PLC 34 to display the monitoring results (determination results) on the touch panel monitor 36 in addition to the display unit 22 of the information terminal 20.

[0077] Furthermore, when it is determined that at least one of the network-related devices is in an abnormal state, the second output unit 34e may output information to the indicator light 37 to display the determination result on the indicator light 37 (to activate the indicator light 37). This enables the information terminal 20 to notify users located around the performance control panel 30 that at least one of the network-related devices is in an abnormal state.

[0078] [Effects, etc.] Hereinafter, examples of inventions that can be obtained from the disclosure of this specification will be given, and the effects and the like that can be obtained from the exemplified inventions will be explained.
