Abstract
Description
[Technical Field]
[0001] FIELD An embodiment of the present invention relates to a lamp management device and a lamp management system. [Background technology]
[0002] Aircraft beacons are used in aircraft passageways such as airport taxiways and runways, and each air traffic beacon comprises fixed equipment and a lamp unit. The fixed equipment has a base, and is installed (fixed) to the roadbed in the aircraft passageway. The lamp unit is then removably attached to the fixed equipment installed on the roadbed. Air traffic beacons undergo periodic maintenance. During lamp unit maintenance, the lamp unit to be maintained is removed from the fixed equipment, and a different lamp unit that has already been maintained is newly installed on the fixed equipment. The lamp unit removed from the fixed equipment is then transported to the airport's back-of-house area, where inspection, servicing, and other maintenance are carried out.
[0003] In aircraft aisles, multiple fixed equipment items are installed in different locations relative to each other. Therefore, when maintenance is performed on a lighting unit as described above, the lighting unit that has undergone maintenance may be installed in a fixed equipment item in a location different from the fixed equipment item that was installed before the maintenance. In other words, the fixed equipment to which a lighting unit is installed is not necessarily limited to one fixed equipment item, and the fixed equipment to which it is installed may change each time maintenance is performed.
[0004] Therefore, for each lighting device used in aircraft corridors, convenience can be improved by allowing the lighting device manager or the like to manage information on the fixed equipment on which the lighting device was installed, in addition to information on each of the multiple components that make up the lighting device. In particular, in aircraft corridors, the installation location of the fixed equipment on which the lighting device was installed has a significant impact on lighting device failures, etc. For this reason, trend observations are being conducted on the impact that the installation location of the fixed equipment on which the lighting device was installed has on the lighting device. Furthermore, trend observations are required to enable the lighting device manager or the like to appropriately grasp the installation location of the fixed equipment that was installed immediately before the maintenance for lighting devices undergoing maintenance in back yards, etc. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION
[0010] In an embodiment, the lighting unit management device 42 includes a management unit 43. The management unit 43 manages, for a lighting unit 11 that is removably attached to fixed equipment 10 installed on the roadbed 2 of an aircraft passageway, part information group data 53 including part information 56 of parts attached to the lighting unit 11, and equipment location information 57 relating to the installation location of the fixed equipment 10 to which the lighting unit 11 was attached, by linking them together. This allows the manager of the lighting unit 11, etc., to appropriately ascertain, from the data about the lighting unit 11 managed by the management unit 43, not only the part information 56 of each of the multiple parts that make up the lighting unit 11, but also the installation location of the fixed equipment 10 to which the lighting unit 11 was attached.
[0011] In the embodiment, a readable equipment-side marking (Ma) is provided on the fixed equipment (10). When the equipment-side marking (Ma) is read on the fixed equipment (10) to which the lighting equipment (11) was attached, the management unit (43) of the lighting equipment management device (42) links the equipment location information (57) of the fixed equipment (10) from which the equipment-side marking (Ma) was read with the part information group data (53) of the lighting equipment (11). As a result, for a lighting equipment (11) that has been removed from the fixed equipment (10) for maintenance or the like, the equipment location information (57) of the fixed equipment (10) to which the lighting equipment (11) was attached can be appropriately linked with the part information (56) of the parts of the lighting equipment (11).
[0012] In the embodiment, a readable lamp-side marking (Mb) is provided on a component of the lamp (11). When the lamp-side marking (Mb) of the component of the lamp (11) is read, the management unit (43) of the lamp management device (42) links the component information (56) of the component from which the lamp-side marking (Mb) was read with the component location information (57) of the fixed equipment (10) on which the lamp (11) was attached. As a result, even if the component information (56) of one or more components in the lamp (11) is updated due to component replacement during maintenance or the like, the component information group data (53) in which the component information (56) of one or more components has been updated can be appropriately linked to the component location information (57) of the fixed equipment (10) on which the lamp (11) was attached.
[0013] The lighting device management system (40) of the embodiment includes a fixed equipment (10), a lighting device (11), and a management unit (43). The fixed equipment (10) is installed on the roadbed (2) of an aircraft passageway. The lighting device (11) includes components and is removably attached to the fixed equipment (10). The management unit (43) manages part information group data (53) including component information (56) of the components of the lighting device (11) in association with equipment location information (57) relating to the installation location of the fixed equipment (10) to which the lighting device (11) was attached. This allows the manager of the lighting device (11), etc., to properly ascertain, from the data about the lighting device (11) managed by the management unit (43), not only the component information (56) of each of the multiple components that make up the lighting device (11) but also the installation location of the fixed equipment (10) to which the lighting device (11) was attached.
[0014] In the lighting fixture management system (40) of the embodiment, the fixed fixture (10) is provided with a readable fixture-side marking (Ma). When the fixture-side marking (Ma) is read on the fixed fixture (10) to which the lighting fixture (11) was attached, the management unit (43) links the fixture location information (57) of the fixed fixture (10) from which the fixture-side marking (Ma) was read with the part information group data (53) of the lighting fixture (11). As a result, for a lighting fixture (11) that has been removed from the fixed fixture (10) for maintenance or the like, the fixture location information (57) of the fixed fixture (10) to which the lighting fixture (11) was attached can be appropriately linked with the part information (56) of the part of the lighting fixture (11).
[0015] In the lighting fixture management system (40) of the embodiment, a component of the lighting fixture (11) has a readable lighting fixture marking (Mb). When the lighting fixture marking (Mb) of the component of the lighting fixture (11) is read, the management unit (43) links the component information (56) of the component from which the lighting fixture marking (Mb) was read to the component location information (57) of the fixed equipment (10) on which the lighting fixture (11) was attached. As a result, even if the component information (56) of one or more components in the lighting fixture (11) is updated due to component replacement during maintenance or the like, the component information group data (53) in which the component information (56) of one or more components has been updated can be appropriately linked to the component location information (57) of the fixed equipment (10) on which the lighting fixture (11) was attached.
[0016] Hereinafter, embodiments will be described with reference to the drawings.
[0017] FIG. 1 schematically illustrates an example of an aircraft beacon 1 according to an embodiment. FIG. 1 illustrates a cross section parallel or approximately parallel to the vertical direction. The aircraft beacon 1 is used in aircraft passageways, such as taxiways and runways, at airports. Here, in aircraft passageways, such as taxiways, a roadbed (not shown) is formed over the entire aircraft passageway. In addition, in the aircraft passageway, one or more roadbeds 2 are arranged vertically above the roadbed, and the roadbeds 2 form a road surface (passage surface) 3. In other words, the roadbed 3 is a part of the roadbed 2, and the surface of the roadbed 2 is the road surface 3. The roadbed 2 is formed from asphalt, an asphalt-concrete composite, crushed stone cement, or the like. Note that FIG. 1 illustrates only one roadbed 2.
[0018] As shown in FIG. 1, an aircraft beacon 1 comprises a fixed component 10 and a lamp unit 11. In the example shown in FIG. 1, the aircraft beacon 1 comprises a base 12, an adjustment ring 13, and a spacer 15 as the fixed component 10. A hole 5 recessed vertically downward from the road surface 3 is formed in the roadbed 2 of the aircraft passage. The fixed component 10 is installed inside the hole 5 and fixed to the roadbed 2. The fixed component 10 is inserted into the roadbed 2, and the base 12 and the spacer 15 do not protrude vertically upward from the road surface 3. In the aircraft beacon 1, the lamp unit 11 is attached vertically from above to the fixed component 10 installed inside the hole 5. The lamp unit 11 is removably attached to the fixed component 10 fixed to the roadbed 2.
[0019] In the example shown in FIG. 1 , a base 12 is installed at the bottom of the hole 5, and a spacer 15 is attached to the base 12 from above vertically. Then, an adjustment ring 13 is attached to the spacer 15 from above vertically. Then, the lighting device 11 is installed on the adjustment ring 13 from above vertically, and is attached to the base 12 with the adjustment ring 13 and the spacer 15 interposed between them. Note that in one example, the spacer 15 is not provided as the fixed device 10, and the fixed device 10 is formed by the base 12 and the adjustment ring 13. In this case, the adjustment ring 13 is attached directly to the base 12 from above vertically. Then, the lighting device 11 is attached to the base 12 with only the adjustment ring 13 interposed between them.
[0020] When the lighting device 11 is attached to the fixed equipment 10 as described above, at least a portion of the lighting device 11 protrudes vertically upward from the road surface 3, and at least a portion of the lighting device 11 is exposed at the road surface 3. In addition, a power line 16 is extended inside the roadbed 2, and in aircraft passages such as taxiways, the power line 16 is buried in the roadbed 2. The power line 16 can be connected to the lighting device 11. When the power line 16 is connected to the lighting device 11, power is supplied to the lighting device 11 through the power line 16.
[0021] In the embodiments, a readable marking Ma is provided on the fixed material 10. In the example shown in FIG. 1, the marking Ma is provided on the adjustment ring 13. In one example, the marking Ma may be formed on the base 12 or the spacer 15. The marking Ma may be formed on at least one of these components, and may be formed on two or more of these. The marking Ma is preferably provided in a position that is not exposed to the outside when the lighting device 11 is attached to the fixed material 10. The marking Ma is, for example, a two-dimensional code or a barcode. Examples of two-dimensional codes that can be used as the marking Ma include QR Code (registered trademark) and Data Matrix (registered trademark). In the fixed material 10, the marking Ma may be formed on a tag or the like attached to the fixed material 10, or a sticker or the like on which the marking Ma is formed may be attached to the fixed material 10.
[0022] From the viewpoint of making the marking Ma easier to read, it is preferable that the marking Ma be formed on the adjustment ring 13 located close to the road surface 3. The marking Ma provided on the fixed equipment 10 is also referred to as the "equipment side marking" or the "fixed side marking." In Figure 1 etc., the marking Ma is shown in black.
[0023] FIG. 2 shows a schematic diagram of an example of the configuration of a lighting device 11 according to an embodiment. As shown in FIG. 2, a height direction (the direction indicated by arrows Z1 and Z2) is defined for the lighting device 11. One side of the lighting device 11 in the height direction is the upper side (the arrow Z1 side), and the side opposite the upper side in the height direction is the lower side (the arrow Z2 side). The lighting device 11 is attached to the fixed equipment 10 with the upper side in the height direction coinciding or nearly coinciding with the vertical upper side. FIG. 2 shows a cross section parallel or nearly parallel to the height direction.
[0024] The lighting device 11 includes a plurality of parts and is composed of a plurality of parts. The lighting device 11 includes an upper light body 21, a lower light body 22, a lighting unit (power supply unit) 23, and light source units 25, 26, and the upper light body 21, the lower light body 22, the lighting unit 23, and the light source units 25, 26 are each one of the plurality of parts that make up the lighting device 11. In the lighting device 11, the upper light body 21 and the lower light body 22 form an exterior portion, and an internal cavity 27 surrounded by the upper light body 21 and the lower light body 22 is formed inside the exterior portion. In the exterior portion of the lighting device 11, the upper light body 21 is attached to the lower light body 22 from above in the height direction. The upper light body 21 covers the internal cavity 27 from above in the height direction, and the lower light body 22 covers the internal cavity 27 from below in the height direction.
[0025] Two window portions 31, 32 are formed in the upper light body 21. When the lighting device 11 is attached to the fixed equipment 10, a portion of the upper light body 21 protrudes vertically upward from the road surface 3, and the window portions 31, 32 are located in the portion of the upper light body 21 that protrudes from the road surface 3. Therefore, when the lighting device 11 is attached to the fixed equipment 10, the window portions 31, 32 are exposed at the road surface 3. Each of the window portions 31, 32 transmits light such as visible light. However, in the exterior portion formed by the upper light body 21 and the lower light body 22, portions other than the window portions 31, 32 do not transmit light such as visible light, or transmit very little light.
[0026] The lighting unit 23 and the light source units 25, 26 are housed in the internal cavity 27. In one example such as FIG. 2, an installation plate 33 is disposed in the internal cavity 27. The installation plate 33 has an upper plate surface 35 facing upward in the height direction of the lamp 11 and a lower plate surface 36 facing downward in the height direction of the lamp 11. The light source units 25, 26 are disposed on the upper plate surface 35, and the lighting unit 23 is disposed on the lower plate surface 36. For this reason, in one example such as FIG. 2, the lighting unit 23 is disposed below the light source units 25, 26 in the height direction. Note that the numbers of the lighting units 23 and the light source units 25, 26 are merely examples and are not limited to those in this embodiment.
[0027] The lighting unit 23 converts the power supplied through the power line 16 into power corresponding to each of the light source units 25, 26. The lighting unit 23 then supplies the converted power to each of the light source units 25, 26. Each of the light source units 25, 26 may include a light emitting element such as an LED (light emitting diode), or may be configured with a lamp other than an LED. When power is supplied to each of the light source units 25, 26, the light source units 25, 26 perform a light emitting operation and emit light such as visible light.
[0028] In the internal cavity 27, the light source unit 25 is disposed opposite the window unit 31, and the light source unit 26 is disposed opposite the window unit 32. The light emitted from the light source unit 25 passes through the window unit 31 and is irradiated to the outside of the lighting device 11. The light emitted from the light source unit 26 passes through the window unit 32 and is irradiated to the outside of the lighting device 11. When the lighting device 11 is attached to the fixed equipment 10, the light from the light source units 25, 26 is irradiated to either the aircraft or the ground (road surface 3, etc.) in an aircraft passageway such as a taxiway.
[0029] In the embodiments and the like, a readable marking Mb is provided on each of the multiple components of the lighting device 11. In one example such as Fig. 2, markings Mb1, Mb2, Mb3, Mb4, and Mb5 are provided on the upper light body 21, the lower light body 22, the lighting unit 23, and the light source parts 25 and 26, respectively. Like the marking Ma, each of the markings Mb is, for example, a two-dimensional code or a barcode, and examples of two-dimensional codes that can be used as the marking Mb include a QR code and a data matrix.
[0030] For each component of the lighting device 11, the marking Mb may be formed on a tag or the like attached to the component, or a sticker or the like with the marking Mb formed on it may be affixed to the component. The marking Mb provided on each of the multiple components in the lighting device 11 is also referred to as a "lighting device-side marking." In addition, in Figure 2, each of the markings Mb is shown in black.
[0031] Each of the markings Ma and Mb can be read using a reading device such as a code reader or a code scanner. In embodiments, it is preferable that the markings Mb of each component of the lighting fixture 11 can be read using a reading device that can read the marking Ma of the fixed equipment 10. In one example, the marking Mb is formed from the same type of code as the marking Ma. In another example, the marking Mb is formed from a type of code different from that of the marking Ma, and the reading device can read multiple types of codes including the markings Ma and Mb. By reading each of the markings Ma and Mb, information associated with that marking (the corresponding one of Ma and Mb) is acquired by the reading device, etc.
[0032] In the fixed equipment 10, the marking Ma is linked to equipment location information relating to the installation location of the fixed equipment 10. In one example, as the equipment location information of the fixed equipment 10, position information of the fixed equipment 10, such as the position coordinates of the fixed equipment 10 in real space, is linked (associated) with the marking Ma. The position information of the fixed equipment 10 may indicate an absolute position, such as position coordinates based on a GPS (Global Positioning System) or a geographic information system, or may read a relative position based on a reference position at or near the airport. An absolute position, such as position coordinates based on a GPS or a geographic information system, can be measured, for example, by wireless communication with a GPS satellite using a wireless terminal or the like. A relative position based on a reference position can be measured, for example, by wireless communication with a radio wave transmitter located at a reference position at the airport using a wireless terminal or the like.
[0033] In another example, identifier information of the fixed equipment 10, such as the management number or management symbol of the fixed equipment 10, is linked (associated) with the marking Ma as equipment location information of the fixed equipment 10. In this case, for each of the fixed equipment 10 installed in the aircraft passageway, the installation location where it is installed (fixed) to the roadbed 2 can be identified from the identifier information, such as the management number or management symbol, using an airport management system or the like.
[0034] For each component of the lighting device 11, the marking Mb is linked to the component information of that component. In the example of FIG. 2, the markings Mb1, Mb2, Mb3, Mb4, and Mb5 are linked to the component information of the upper lamp body 21, the lower lamp body 22, the lighting unit 23, and the light source units 25 and 26, respectively. Here, for each component of the lighting device 11, the part number, product name, quantity installed in the lighting device 11, quantity used in the lighting device 11, and replacement history, etc., of that component are linked (associated) with the marking Mb as component information. The component information for each component indicates whether or not the component has been replaced as the replacement history, and for components that have been replaced, the replacement date, reason for replacement, etc. are indicated as the replacement history. Furthermore, for components that are installed in multiple installation positions in the lighting device 11, such as the light source units 25 and 26, information regarding the installation positions is linked to the marking Mb as component information.
[0035] Furthermore, in one example, for at least one or more components constituting the lighting device 11, the marking Mb may be linked to lighting device information, which is information about the entire lighting device 11, in addition to the component information of that component. The lighting device information indicates identifier information of the lighting device 11, such as the identification number of the lighting device 11. Furthermore, for lighting devices 11 for which measurements of characteristics such as optical characteristics have been performed, the measurement results of the characteristics are indicated as lighting device information. Furthermore, for lighting devices 11 that have been inspected, information about the inspection may be indicated as lighting device information. Information about the inspection may include, for example, the inspection date, information about the worker who performed the inspection, and the inspection details.
[0036] In one example, a marking (first lamp-side marking) Mb is provided on each of a plurality of components in the lamp 11, and a marking Mc (Mc not shown) separate from the marking Mb is also provided on the lamp 11. The marking (second lamp-side marking) Mc, like the markings Ma and Mb, is, for example, a two-dimensional code or a barcode, and can be read using a reading device. By reading the marking Mc, information linked to the marking Mc is acquired by the reading device, etc. In this example, the marking Mc is linked to lamp-side information, which is information about the entire lamp 11.
[0037] Here, in the aircraft beacon light 1, maintenance of the lighting units 11 is performed periodically, for example, every six months or one year. FIG. 3 schematically illustrates an example of work performed in an aircraft corridor, which is the site, during maintenance of the lighting units 11 in an embodiment. As shown in FIG. 3 and other figures, a plurality of fixed equipment 10 are installed in different locations (positions) relative to one another in the aircraft corridor. Then, in the aircraft corridor, a plurality of fixed equipment 10 fixed to the roadbed 2 are arranged. The plurality of fixed equipment 10 may be arranged along the aircraft corridor, or may be arranged in a direction intersecting (perpendicular or approximately perpendicular) the aircraft corridor. Then, in the aircraft corridor, a lighting unit 11 is removably attached to each of the plurality of fixed equipment 10 installed in the roadbed 2.
[0038] In maintenance of the lighting fixture 11, the lighting fixture 11 to be maintained (light fixture 11A) is removed from the fixed equipment 10. Then, another lighting fixture 11 that has been maintained (light fixture 11B) is newly attached to the fixed equipment 10 from which the lighting fixture 11 was removed. In the example of FIG. 3 , lighting fixture 11A is removed from each of multiple fixed equipment 10 fixed to the roadbed 2. Then, lighting fixture 11B that has been maintained and is different from lighting fixture 11A is newly attached to each of the fixed equipment 10.
[0039] Furthermore, during maintenance of the lighting device 11, the lighting device 11 (11A) is removed from the fixed equipment 10 and transported to a back-office area of the airport, where inspection, servicing, and other maintenance are performed. Furthermore, if a part is replaced during maintenance of the lighting device 11, the part information linked to the marking Mb is updated for the replaced part, for example, by updating the marking Mb. At this time, for example, by updating the marking Mb, the date of replacement during maintenance and the reason for replacement are newly added as replacement history to the part information linked to the marking Mb. The marking Mb is updated by attaching a tag bearing the updated marking Mb to the part, or by sticking a sticker bearing the updated marking Mb to the part.
[0040] As described above, when maintenance is performed on a lighting device 11, the lighting device 11 that has undergone maintenance may be attached to a fixed piece of equipment 10 at a different installation location than the fixed piece of equipment 10 to which it was attached before the maintenance. In other words, the fixed piece of equipment 10 to which the lighting device 11 is attached is not necessarily limited to one fixed piece of equipment 10, and the fixed piece of equipment 10 to which the lighting device 11 is attached may be different each time maintenance is performed. In one example, the fixed piece of equipment 10 to which a certain lighting device 11 is attached changes each time maintenance is performed on the lighting device 11, in the order of location η1, location η2, and location η3.
[0041] In the embodiment and the like, information is managed for a plurality of lighting units 11 used in aircraft passageways. Figure 4 is a block diagram showing an example of a lighting unit management system 40 that manages information for a plurality of lighting units 11 in the embodiment. The lighting unit management system 40 constitutes, for example, a part of an airport's computer system.
[0042] As shown in Fig. 4, in the lighting fixture management system 40, the reading device 41 can read the marking Ma in each fixed piece of equipment 10. Therefore, the reading device 41 can obtain equipment location information regarding the installation location of each fixed piece of equipment 10. In the lighting fixture management system 40, for example, when a lighting fixture 11 (lighting fixture 11A) that is the subject of maintenance is removed from the fixed piece of equipment 10, the reading device 41 reads the marking (equipment-side marking) Ma in the fixed piece of equipment 10 to which the lighting fixture 11 was attached. As a result, the reading device 41 obtains information associated with the fixed piece of equipment 10, such as the equipment location information of the fixed piece of equipment 10 from which the marking Ma was read and the installation date of the fixed piece of equipment 10.
[0043] Furthermore, in the lighting device management system 40, the reading device 41 can read the marking Mb of each part in each lighting device 11. Therefore, the reading device 41 can obtain part information for each part in each lighting device 11. In the lighting device management system 40, for example, in an airport backyard or the like, the reading device 41 reads one or more part markings (light device side markings) Mb for a lighting device 11 (light device 11A) that is the subject of maintenance and has been removed from the fixed equipment 10. As a result, the reading device 41 obtains part information for one or more parts whose markings Mb have been read.
[0044] The lighting equipment management system 40 includes a lighting equipment management device 42. The lighting equipment management device 42 performs processing related to information management of the multiple lighting equipment 11 used in aircraft corridors. The lighting equipment management device 42 includes a management unit 43 and a communication unit 45.
[0045] The lighting appliance management device 42 is, for example, a processing device such as a terminal or a server, and the management unit 43, which serves as the processing execution unit, is composed of a processor or integrated circuit mounted on the terminal or server. The processor or integrated circuit that constitutes the management unit 43 includes any of a CPU (Central Processing Unit), ASIC (Application Specific Integrated Circuit), microcomputer, FPGA (Field Programmable Gate Array), DSP (Digital Signal Processor), etc. The management unit 43 may be composed of a single integrated circuit, etc., or may be composed of multiple integrated circuits, etc.
[0046] The communication unit 45 is composed of a communication circuit etc., and the lighting device management device 42 communicates with external devices including the reading device 41 through the communication unit 45. The communication unit 45 performs communication by wire or wirelessly. The communication unit 45 receives information from the outside and transmits information to the outside.
[0047] In one example, the lamp management device 42 is configured by a plurality of processing devices, such as a plurality of servers. In this case, integrated circuits of the plurality of processing devices cooperate with each other to perform the processing described below by the management unit 43. In another example, the lamp management device 42 is configured by a server in a cloud environment. In this case, a virtual processor, such as a virtual CPU, performs the processing described below by the management unit 43.
[0048] The lighting device management system 40 also stores a lighting device database 50 that shows information about the plurality of lighting devices 11 used in aircraft aisles. The lighting device database 50 may be stored in a storage device or the like provided in the lighting device management system 40 or the lighting device management device 42, or may be stored in cloud memory in a cloud environment. The management unit 43 of the lighting device management device 42 performs processing to manage the information shown in the lighting device database 50.
[0049] In the lamp database 50, for each of the multiple lamps 11 used in aircraft passageways, lamp-related data 51, which is data related to that lamp 11, is shown. Below, the data structure etc. of the lamp-related data 51 for any one lamp 11 will be explained. For each of the multiple lamps 11, the data structure etc. of the lamp-related data 51 for that lamp 11 will be the same as the data structure etc. explained below.
[0050] 4 and other figures, the lamp-related data 51 for any one lamp 11 indicates lamp information 52, which is information about the entire lamp 11. As described above, the lamp information 52 indicates the identifier information of the lamp 11, and may also indicate any of the measurement results of the characteristics of the lamp 11, information about the inspection of the lamp 11, etc.
[0051] The lamp-related data 51 for any one lamp 11 indicates part information group data 53 for multiple parts of that lamp 11. The part information group data 53 includes part information 56 for each of multiple parts provided in the lamp 11, and is configured, for example, as a collection of part information 56 for multiple parts. In one example, the part information group data 53 for any one lamp 11 indicates part information 56 for each of the upper lamp body 21, lower lamp body 22, lighting unit 23, and light source units 25, 26. As described above, the part information 56 for each part of the lamp 11 indicates the part's product number, product name, quantity installed in the lamp 11, quantity used in the lamp 11, replacement history, etc.
[0052] The lighting fixture-related data 51 for any one lighting fixture 11 shows location history data 55 that indicates the history (changes over time) of the locations where that lighting fixture 11 has been installed. The location history data 55 shows equipment location information 57 related to the installation location of the fixed equipment 10 to which the lighting fixture 11 was installed. The location history data 55 shows equipment location information 57 for each of one or more fixed equipment 10 to which the lighting fixture 11 has been installed since the start of use, including the fixed equipment 10 to which the lighting fixture 11 was most recently installed. The location history data 55 makes it possible to recognize in which installation location the fixed equipment 10 the lighting fixture 11 has been installed since the start of use.
[0053] The management unit 43 manages the lamp information 52, part information group data 53, and location history data 55 in the lamp related data 51 of any one lamp 11 by linking them to one another (associating them with one another). For this reason, in the lamp related data 51 of the lamp 11, equipment location information 57 regarding the installation location of the fixed equipment 10 to which the lamp 11 was attached is managed by linking it to the part information 56 of each of the multiple parts provided in the lamp 11.
[0054] FIG. 5 is a flowchart outlining an example of processing performed by the management unit 43 of the lighting fixture management device 42 in the embodiment, etc. The example processing of FIG. 5 is initiated, for example, when any one lighting fixture 11 is removed from the fixed equipment 10 for maintenance, etc., by reading the marking Ma of the fixed equipment 10 to which the lighting fixture 11 was attached using a reading device 41, etc. The example processing of FIG. 5 is processing performed on the lighting fixture-related data 51 of any one lighting fixture 11. In the following description, the one lighting fixture 11 that is the target of the example processing of FIG. 5 is referred to as lighting fixture 11α. Note that in the embodiment, etc., the management unit 43 performs processing similar to the example processing of FIG. 5 on the lighting fixture-related data 51 of each of the multiple lighting fixtures 11.
[0055] 5 begins, the management unit 43 receives, from the reader 41 via the communication unit 45, the equipment location information 57 of the fixed equipment 10 from which the marking Ma was read (S101). Then, the management unit 43 reflects the equipment location information 57 of the fixed equipment 10 from which the marking Ma was read in the location history data 55 in the lighting equipment related data 51 of the lighting equipment 11α shown in the lighting equipment database 50 (S102). At this time, the management unit 43 adds, for example, in the location history data 55, the equipment location information 57 of the fixed equipment 10 from which the marking Ma was read as the installation location of the fixed equipment 10 to which the lighting equipment 11α was most recently attached.
[0056] Then, the management unit 43 links the location history data 55 reflecting the equipment location information 57 as described above to the lighting fixture information 52 and the part information group data 53 (S103). As a result, the equipment location information 57 of the fixed equipment 10 from which the marking (equipment-side marking) Ma was read is linked (associated) with the part information group data 53 including the part information 56 of each of the parts of the lighting fixture 11α. In the embodiment etc., the management unit 43 performs the example process of Fig. 5, and therefore, in response to the marking (equipment-side marking) Ma being read in the fixed equipment 10 to which any one lighting fixture 11α was attached, the equipment location information 57 of the fixed equipment 10 from which the marking Ma was read is linked to the part information group data 53 of the lighting fixture 11α.
[0057] FIG. 6 is a flowchart outlining an example of processing different from that shown in FIG. 5, which is performed by the management unit 43 of the lamp management device 42 in the embodiment, etc. The example processing in FIG. 6 is started, for example, by reading the markings Mb of one or more parts in any one lamp 11 that is the object of maintenance using a reading device 41, etc. The example processing in FIG. 6 is processing performed on the lamp-related data 51 of any one lamp 11. In the following description, the any one lamp 11 that is the object of the example processing in FIG. 6 is referred to as lamp 11α. Note that in the embodiment, etc., the management unit 43 performs processing similar to the example processing in FIG. 6 on the lamp-related data 51 of each of the multiple lamps 11.
[0058] 6 begins, the management unit 43 receives, from the reading device 41 via the communication unit 45, the component information 56 for each of the one or more components for which the marking Mb has been read in the lamp 11α (S111). The management unit 43 then reflects the component information 56 for each of the one or more components for which the marking Mb has been read in the lamp related data 51 for the lamp 11α indicated in the lamp database 50 in the component information group data 53 (S112). At this time, the management unit 43 updates the component information 56 for each of the one or more components for which the marking Mb has been read in the component information group data 53, for example, by adding or changing the information.
[0059] Then, the management unit 43 links the part information group data 53 reflecting the part information 56 of one or more parts as described above to the lighting device information 52 and the location history data 55 (S113). As a result, the part information 56 of one or more parts from which the marking (light device side marking) Mb has been read in the lighting device 11α is linked (associated) with the location history data 55 that indicates the history of locations where the lighting device 11α has been installed. In the embodiment etc., the management unit 43 performs the example process of Fig. 6, and therefore, in response to the marking (light device side marking) Mb being read from one or more parts among the multiple parts of any one lighting device 11α, the part information 56 of the one or more parts from which the marking Mb has been read is linked to equipment location information 57 of the fixed equipment 10 to which the lighting device 11α was installed.
[0060] As described above, in the lighting fixture database 50, in the lighting fixture related data 51 for each lighting fixture 11, part information 56 for one or more parts in the part information group data 53 is updated, and equipment location information 57 is added to the location history data 55. That is, in response to the reading of a marking Ma of any fixed equipment 10 or the reading of a marking Mb of one or more parts in any lighting fixture 11, the information shown in the lighting fixture database 50 is updated by the management unit 43.
[0061] The workers travel between the aircraft passageway, which is the work site, and the back yard by vehicle, etc. In one example, the lighting equipment management device 42 is configured as a portable terminal, and the example of the process in Fig. 5 and the example of the process in Fig. 6 are performed while traveling by vehicle. In this case, the information shown in the lighting equipment database 50 is updated using the lighting equipment management device 42 configured as a portable terminal while traveling by vehicle.
[0062] Fig. 7 shows an example of updating information in the lamp database 50, which is performed by the management unit 43 of the lamp management device 42 in the embodiment. In the example of Fig. 7, lamp-related data 51 is shown for each of a plurality of lamps 11 in the lamp database 50, and in the lamp-related data 51 for each of the lamps 11, lamp information 52, part information group data 53, and location history data 55 are linked to one another. In the example of Fig. 7, for each of the plurality of lamps 11, identifier information for the lamp 11 is shown as lamp information 52. In the example of Fig. 7, lamp-related data 51 is shown for each of a plurality of lamps 11, including lamps 11 whose identifier information is identifiers γ1 and γ2.
[0063] 7, maintenance is performed on each of the multiple lighting devices 11, and the lighting device-related data 51 for each lighting device 11 is updated during the maintenance. In the example of FIG. 7, the part information group data 53 for each of the multiple lighting devices 11 indicates part information 56 for multiple parts including the upper light body 21 and the lower light body 22. During the maintenance, the lower light body 22 is replaced in the lighting device 11 with identifier γ2. Note that during the maintenance, none of the parts are replaced in the lighting device 11 with identifier γ1, and no parts other than the lower light body 22 are replaced in the lighting device 11 with identifier γ2.
[0064] For this reason, during maintenance, in the part information group data 53 of the lamp 11 with identifier γ1, the part information 56 of the upper lamp body 21 is not changed from information εa1, and the part information 56 of the lower lamp body 22 is not changed from information εb1. Then, during maintenance, in the part information group data 53 of the lamp 11 with identifier γ2, the part information 56 of the upper lamp body 21 is not changed from information εa2, and the part information 56 of the lower lamp body 22 is changed (updated) from information εb2 to information εb3. At this time, in the lower lamp body 22 of the lamp 11 with identifier γ2, the part information linked to the marking Mb is updated, for example, by updating the marking Mb. Then, in response to the reading of the updated marking Mb, information regarding the replacement of the lower lamp body 22 in the lamp 11 with identifier γ2 is added to the information εb2, and the information εb2 is updated to information εb3.
[0065] Furthermore, during maintenance, for each of the multiple lighting devices 11, the marking Ma of the fixed device 10 to which that lighting device 11 was most recently attached is read to obtain device location information 57 of the fixed device 10 to which that lighting device 11 was most recently attached. Then, in the location history data 55 of each of the multiple lighting devices 11, the device location information 57 obtained during maintenance is added as the installation location of the fixed device 10 to which that lighting device 11 was most recently attached.
[0066] In the lighting fixture database 50 before the information is updated, the location history data 55 for the lighting fixture 11 with identifier γ1 indicates that the lighting fixture 11 with identifier γ1 was attached to the fixed equipment 10 at location η1 until its previous maintenance was performed. Then, the location history data 55 for the lighting fixture 11 with identifier γ2 indicates that the lighting fixture 11 with identifier γ2 was attached to the fixed equipment 10 at location η2 until its previous maintenance was performed. Then, in the lighting fixture database 50 after the information is updated, the location history data 55 for the lighting fixture 11 with identifier γ1 adds information that the lighting fixture 11 with identifier γ1 was attached to the fixed equipment 10 at location η2 from its previous maintenance until its current maintenance. Then, the location history data 55 for the lighting fixture 11 with identifier γ2 adds information that the lighting fixture 11 with identifier γ2 was attached to the fixed equipment 10 at location η3 from its previous maintenance until its current maintenance.
[0067] In one example, the lighting device management system 40 is provided with a measurement result management device and an examination information management device. Each of the measurement result management device and the examination information management device is, for example, a processing device such as a terminal or a server. The measurement result management device manages measurement results of characteristics such as optical characteristics for each of the lighting devices 11. The examination information management device manages information related to examinations performed on each of the lighting devices 11. The communication unit 45 of the lighting device management device 42 is capable of communicating with each of the measurement result management device and the examination information management device via wired or wireless communication. In this example, the lighting device management device 42 is linked to other management devices such as the measurement result management device and the examination information management device to manage information about each of the lighting devices 11. The lighting device management device 42 is then able to share information about each of the lighting devices 11 with the other management devices.
[0068] As described above, in the embodiments, the management unit 43 of the lighting fixture management device 42 manages, for the lighting fixture 11, the part information group data 53 including part information 56 for each of the multiple parts provided in the lighting fixture 11, and the equipment location information 57 relating to the installation location of the fixed equipment 10 to which the lighting fixture 11 was attached, by linking these data together. Therefore, the manager of the lighting fixture 11 can properly ascertain, from the data about the lighting fixture 11 managed by the management unit 43 (lamp-related data 51), not only the part information 56 for each of the multiple parts that make up the lighting fixture 11, but also the installation location of the fixed equipment 10 to which the lighting fixture 11 was attached.
[0069] For each of the lighting units 11 used in aircraft aisles, trend observations are made regarding the impact that the installation location of the fixed equipment 10 to which the lighting unit 11 was attached has on the lighting unit 11 (the components of the lighting unit 11, etc.). In the embodiments, as described above, for each of the lighting units 11, the component information 56 for each of the multiple components of the lighting unit 11 is linked to the equipment location information 57 of the fixed equipment 10 to which the lighting unit 11 was attached and managed. For this reason, by performing trend observations using data about the lighting units 11 managed by the management unit 43 (lighting unit-related data 51), it becomes possible for a manager or the like to properly grasp, for each lighting unit 11 undergoing maintenance, the installation location of the fixed equipment 10 that was attached immediately before the maintenance, and to perform trend observations in detail.
[0070] Furthermore, in one example of the embodiments, in response to the reading of marking (equipment-side marking) Ma on the fixed equipment 10 on which the lighting equipment 11 was attached, the management unit 43 links the equipment location information 57 of the fixed equipment 10 from which the marking Ma was read to the part information group data 53 of the lighting equipment 11. Therefore, for a lighting equipment 11 that has been removed from the fixed equipment 10 for maintenance or the like, the equipment location information 57 of the fixed equipment 10 on which the lighting equipment 11 was attached is appropriately linked to the part information 56 of the parts of the lighting equipment 11.
[0071] Furthermore, in one example of the embodiments, when marking (lamp-side marking) Mb is read on one or more of the multiple components of the lighting fixture 11, the management unit 43 links the component information 56 of the one or more components from which the marking Mb is read with the component location information 57 of the fixed equipment 10 to which the lighting fixture 11 is attached. Therefore, even if the component information 56 of one or more components in the lighting fixture 11 is updated due to component replacement during maintenance or the like, the component information group data 53 in which the component information 56 of the one or more components has been updated is appropriately linked to the component location information 57 of the fixed equipment 10 to which the lighting fixture 11 is attached.
[0072] According to at least one of these embodiments, for a lighting unit that is removably attached to fixed equipment installed in an aircraft aisle, part information group data containing part information for each of a plurality of parts attached to the lighting unit and equipment location information relating to the installation location of the fixed equipment to which the lighting unit was attached are managed in association with each other. This makes it possible to provide a lighting unit management device and a lighting unit management system that can manage not only part information for the parts that make up the lighting unit, but also information about the fixed equipment to which the lighting unit was attached.
[0073] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
