[0026] (1.2.1) Support The support pillar 2 is made of metal. As shown in FIG.
[0027] The support body 21 has a tubular shape that is long in one direction. The support body 21 has, for example, a cylindrical shape.
[0028] The pillar 2 is installed on the ground 109 so that the length direction of the pillar body 21 is along the up-down direction. In other words, the pillar 2 is installed on the road 100 so that the length direction of the pillar body 21 coincides with the vertical direction. Note that the pillar 2 may be installed so that the length direction of the pillar body 21 is offset from the vertical direction by an angle within an allowable range (e.g., ±20 degrees).
[0029] When the ground 109 is horizontal, the support pole 2 is installed perpendicular to the ground 109. When the ground 109 is inclined with respect to the horizontal direction due to a slope or the like, the support pole 2 is installed at an angle with respect to the ground 109.
[0030] The pillar 2 is installed outdoors (on the ground 109) so that the tip of the lower end of the pillar body 21 is buried in the ground (see FIG. 5). The lower end of the pillar body 21 is buried in the ground. In this embodiment, the "lower end of the pillar body 21" includes a part buried in the ground (tip) and a part exposed from the ground. Hereinafter, the part of the lower end of the pillar body 21 buried in the ground is also referred to as the "buried part 211". In addition, the part of the lower end of the pillar body 21 exposed from the ground 109 is also referred to as the "exposed part 212".
[0031] The arm 22 protrudes from the upper end of the pillar body 21 in a direction intersecting the longitudinal axis of the pillar body 21. The arm 22 is, for example, cylindrical. As shown in Fig. 3, the arm 22 protrudes obliquely upward from the upper end of the pillar body 21.
[0032] The arm 22 holds the illumination light 3 and the surveillance camera 6 .
[0033] The support pole 2 has a length such that the illuminating lamp 3 held by the arm 22 is positioned at a height of about 4.5 to 5 m above the ground 109, for example.
[0034] (1.2.2) Lighting The illuminating lamp 3 is held by the support pole 2 on the side of the upper end of the support pole body 21. The illuminating lamp 3 is held by an arm 22 of the support pole 2.
[0035] 4, the illuminating lamp 3 includes a high-voltage cutoff unit 31, a power supply circuit (hereinafter also referred to as a "first power supply circuit") 32, a control unit 33, an illumination unit 34, an illuminance sensor 35, a short-range communication unit (hereinafter also referred to as a "first short-range communication unit") 36, a memory 37, and a housing 30 (see FIG. 3). The illuminating lamp 3 is connected to a commercial power system AC1 by, for example, a power cable L1, and is supplied with AC power from the power system AC1.
[0036] The first power supply circuit 32 includes, for example, a rectifier circuit, a converter circuit (AC / DC converter, DC / DC converter), etc. The first power supply circuit 32 converts AC power supplied from the power system AC1 via the power cable L1 into lighting power for lighting the illumination unit 34, and supplies the lighting power to the illumination unit 34. The first power supply circuit 32 also converts AC power supplied from the power system AC1 via the power cable L1 into operating power for the control unit 33, and supplies the operating power to the control unit 33. The first power supply circuit 32 also supplies operating power to the surveillance camera 6.
[0037] The illumination unit 34 includes a light source. The light source includes, for example, a plurality of LEDs. The illumination unit 34 is supplied with lighting power for lighting the light source from the first power supply circuit 32. The illumination unit 34 illuminates an illumination area R1 (see FIG. 3). The illumination area R1 is set below the illuminating lamp 3.
[0038] The memory 37 is connected to the control unit 33. The memory 37 includes one or more storage devices. The memory 37 is used to store various information such as information used by the control unit 33.
[0039] The control unit 33 controls the operation (turning on and off) of the illumination unit 34. The control unit 33 controls the operation of the illumination unit 34 based on information stored in the memory 37, etc. The control unit 33 controls the operation of the illumination unit 34 based on the illuminance (ambient brightness) detected by the illuminance sensor 35.
[0040] The high voltage cut-off unit 31 is provided in front of the first power supply circuit 32. The high voltage cut-off unit 31 is, for example, a lightning arrester (arrester). The lightning arrester is, for example, a varistor (non-linear resistance element). When a high voltage is applied, the high voltage cut-off unit 31 cuts off the electric path to prevent an overcurrent from flowing into the control unit 33 and the lighting unit 34. The lighting lamp 3 is placed at a relatively high position (4.5 to 5 m above the ground 109). Therefore, the high voltage cut-off unit 31 is provided as a measure against lightning strikes.
[0041] The illuminance sensor 35 is connected to the control unit 33. The illuminance sensor 35 detects the illuminance (brightness) of a detection target area. The detection target area of the illuminance sensor 35 includes the area where the surveillance mark 7 is provided.
[0042] The first short-range communication unit 36 is a communication interface. The first short-range communication unit 36 is connected to the control unit 33. The first short-range communication unit 36 has a function of communicating with the third short-range communication unit 64 of the surveillance camera 6. The first short-range communication unit 36 communicates with the third short-range communication unit 64 wirelessly. The first short-range communication unit 36 may include a wireless communication interface that complies with standards such as Wi-SUN (registered trademark), Bluetooth (registered trademark), and ZigBee (registered trademark). The first short-range communication unit 36 may communicate with the third short-range communication unit 64 in a wired manner.
[0043] The housing 30 holds a high voltage cut-off unit 31, a first power supply circuit 32, a control unit 33, an illumination unit 34, an illuminance sensor 35, a first short-range communication unit 36, and a memory 37. The housing 30 accommodates, for example, the high voltage cut-off unit 31, the first power supply circuit 32, the control unit 33, the illumination unit 34, the illuminance sensor 35, the first short-range communication unit 36, and the memory 37 inside. The housing 30 includes a transparent cover unit that covers the illumination unit 34 and transmits light (visible light) emitted from the illumination unit 34.
[0044] The housing 30 is held by the support 2 near the upper end of the support body 21. The housing 30 is held by an arm 22 of the support 2. The housing 30 is held by the arm 22 in an orientation such that light from the illumination unit 34 is emitted downward.
[0045] The power cable L1 connects between the illuminating lamp 3 and the power system AC1. The power cable L1 includes a pair of electric wires. A first end of the power cable L1 is connected to the illuminating lamp 3 (high voltage cutoff unit 31). For example, the power cable L1 is drawn into the inside of the hollow arm 22 through a hole formed in the arm 22, passes through the inside of the arm 22 and the inside of the hollow pillar body 21, and is drawn out to the outside of the pillar 2 from an opening at the lower end of the pillar body 21. A second end of the power cable L1 is connected to the power system AC1 outside the pillar 2. Note that the hole formed in the arm 22 (the hole through which the power cable L1 is drawn) is blocked by the housing 30 of the illuminating lamp 3.
[0046] In order to improve the workability of wiring the power cable L1, an opening may be formed at the upper end of the pillar body 21. The opening at the upper end of the pillar body 21 is closed, for example, by a lid called a cap.
[0047] (1.2.3) Deterioration detection device The deterioration detection device 4 detects deterioration of the pillar 2. The deterioration detection device 4 detects deterioration of the pillar main body 21. The deterioration detection device 4 detects deterioration of the lower end part of the pillar main body 21. The deterioration detection device 4 detects deterioration of the buried part 211 of the pillar main body 21.
[0048] In the outdoor lighting device 1, the support pole 2 may corrode due to exposure to wind and rain. If the outdoor lighting device 1 is installed near the sea, the support pole 2 is likely to corrode due to the influence of salty sea breezes and seawater. If the outdoor lighting device 1 is a street light, the support pole 2 is likely to corrode due to the influence of animals such as dogs and cats' urine, snow-melting agents, and the like. Corrosion of the support pole 2 is likely to occur at the lower end of the support pole body 21, and is particularly likely to occur at the buried portion 211. If corrosion occurs at the lower end of the support pole body 21, the strength of the support pole 2 may decrease.
[0049] Therefore, the deterioration detection device 4 performs a deterioration detection operation to detect whether or not the lower end portion of the pillar body 21 of the pillar 2, particularly the buried portion 211, has deteriorated.
[0050] 5, the deterioration detection device 4 is attached to the lower end of the pillar body 21. The deterioration detection device 4 is attached to the exposed portion 212 at the lower end of the pillar body 21.
[0051] As shown in FIG. 5, the deterioration detection device 4 includes a plurality of detection modules 41 (four in this example, only three are shown in FIG. 5) and a belt .
[0052] The belt 42 is wrapped around the outer periphery of the pillar body 21 and attached to the pillar body 21. The belt 42 holds a plurality of detection modules 41. The belt 42 holds the plurality of detection modules 41 such that the plurality of detection modules 41 are positioned at predetermined intervals around the pillar body 21. Here, the belt 42 holds the four detection modules 41 such that the four detection modules 41 are positioned at 90 degree intervals around the pillar body 21.
[0053] By using the belt 42 to attach the detection module 41 to the pillar body 21, it becomes possible to attach the deterioration detection device 4 to an already installed pillar 2. In addition, the deterioration detection device 4 can be easily replaced.
[0054] The detection module 41 has a function of detecting whether or not the lower end of the pillar body 21 has deteriorated.
[0055] In this embodiment, the detection module 41 is a device for detecting deterioration of the pillar body 21 by ultrasonic flaw detection. That is, the detection module 41 generates ultrasonic waves inside the pillar body 21 (metal part) and measures the reflected waves. For example, the detection module 41 generates ultrasonic waves inside the pillar body 21, causes them to travel toward the buried part 211, and measures the reflected waves. This makes it possible to detect the presence or absence of corrosion in the pillar body 21. If corrosion does not occur at the lower end of the pillar body 21, the ultrasonic waves generated by the detection module 41 are reflected at the lower end of the pillar body 21 and then detected by the detection module 41. On the other hand, if corrosion occurs at the lower end of the pillar body 21, the ultrasonic waves are reflected at the corroded part, so that the reflected waves are detected in a shorter time than when corrosion does not occur. This allows the deterioration detection device 4 to detect the occurrence of corrosion in the pillar body 21.
[0056] The detection module 41 includes, for example, a coil for generating an eddy current inside the pillar body 21, and a magnet for generating a static magnetic field in a direction penetrating the pillar body 21. The detection module 41 generates ultrasonic waves inside the pillar body 21 by the interaction between the eddy current and the static magnetic field by passing a pulse current through the coil.
[0057] As described above, the multiple detection modules 41 are arranged at predetermined intervals around the pillar body 21. This makes it possible to carry out inspection over approximately the entire circumference of the pillar body 21, even when detecting deterioration of the pillar body 21 using straight-line ultrasonic waves.
[0058] As shown in FIG. 4, the deterioration detection device 4 further includes a power supply circuit (hereinafter also referred to as a "second power supply circuit") 43, a control unit 44, a memory 45, a short-range communication unit (hereinafter also referred to as a "second short-range communication unit") 46, and an audio device 47.
[0059] The second power supply circuit 43 is connected to the power system AC1 by, for example, a power cable L2, and is supplied with AC power from the power system AC1. The second power supply circuit 43 includes, for example, a rectifier circuit, a converter circuit (AC / DC converter, DC / DC converter), and the like. The second power supply circuit 43 converts the AC power supplied from the power system AC1 via the power cable L2 into operating power for operating the control unit 44, and supplies the operating power to the control unit 44. The second power supply circuit 43 also supplies power to the detection module 41, the audio device 47, and the like.
[0060] The second short-range communication unit 46 is a communication interface. The second short-range communication unit 46 is connected to the control unit 44. The second short-range communication unit 46 has a function of communicating with the third short-range communication unit 64 of the surveillance camera 6. The second short-range communication unit 46 communicates with the third short-range communication unit 64 wirelessly. The second short-range communication unit 46 may include a wireless communication interface that complies with standards such as Wi-SUN (registered trademark), Bluetooth (registered trademark), and ZigBee (registered trademark). The second short-range communication unit 46 may communicate with the third short-range communication unit 64 via a wired connection.
[0061] The memory 45 is connected to the control unit 44. The memory 45 includes one or more storage devices. The memory 45 is used to store various information such as information used by the control unit 44.
[0062] The control unit 44 is connected to the detection module 41. The control unit 44 controls the operation of the detection module 41. The control unit 44 controls the operation of the detection module 41 based on information stored in the memory 45, etc. The control unit 44 uses the detection data detected by the detection module 41 to determine whether or not the pillar body 21 has deteriorated.
[0063] Specifically, the control unit 44 receives an instruction (hereinafter, also referred to as an "inspection start instruction") from the management device 9 via the long-distance communication unit 65 and the third short-distance communication unit 64 of the surveillance camera 6, and the second short-distance communication unit 46. When the control unit 44 receives the inspection start instruction from the management device 9, it operates the detection module 41. The control unit 44 operates, for example, the four detection modules 41 at different timings. For example, the control unit 44 operates the four detection modules 41 sequentially in a predetermined order and at a predetermined time interval. The control unit 44 acquires detection data indicating the detection result from the detection module 41. For example, the control unit 44 judges the presence or absence of deterioration of the support 2 (support body 21) by comparing the detection data acquired from the detection module 41 with a reference value. As the reference value used for judging the deterioration of the support 2, the detection data when the support 2 is newly installed or when it is confirmed thereafter that there is no corrosion in the support 2 may be used. The control unit 44 transmits information indicating the determination result to the management device 9 via the second short-range communication unit 46 and the third short-range communication unit 64 and long-range communication unit 65 of the surveillance camera 6.
[0064] In this way, the deterioration detection device 4 performs the deterioration detection operation in response to an inspection start instruction from the management device 9, and transmits information indicating the determination result to the management device 9. This allows the user of the management device 9 to remotely check the degree of deterioration of the outdoor lighting device 1.
[0065] The acoustic device 47 is connected to the control unit 44. The acoustic device 47 is attached to the lower end of the pillar body 21. The acoustic device 47 includes, for example, a speaker. The acoustic device 47 is controlled by the control unit 44 to generate sound or voice. The sound emitted from the acoustic device 47 may include a beep sound stored in the memory 45. The sound emitted from the acoustic device 47 may include an artificial voice stored in the memory 45. The sound emitted from the acoustic device 47 may include the voice of the user of the management device 9 inputted to the input unit 94 (voice input unit) of the management device 9.
[0066] The power cable L2 connects between the deterioration detection device 4 and the power system AC1. The power cable L2 includes a pair of electric wires. A first end of the power cable L2 is connected to the deterioration detection device 4 (second power supply circuit 43). The power cable L2 extends downward along the outer circumferential surface of the pillar body 21. A second end of the power cable L2 is connected to the power system AC1 outside the pillar 2.
[0067] In addition, no through holes for passing the power cables L1 to L3 etc. are provided at the lower end of the pillar body 21. The reason is that if such a through hole is provided at the lower end of the pillar body 21, the strength of the lower end of the pillar body 21 may decrease, and the presence of a through hole may affect the judgment of the presence or absence of deterioration (deterioration judgment) by the deterioration detection device 4. In other words, the ultrasonic waves from the detection module 41 may be reflected at the through hole part of the pillar body 21. Therefore, it is preferable not to provide a through hole in the part of the pillar body 21 between the deterioration detection device 4 and the lower end of the pillar body 21 and in the part of the pillar body 21 above the deterioration detection device 4, which has the same length as the length from the deterioration detection device 4 to the lower end of the pillar body 21.
[0068] Here, the deterioration detection device 4 does not include a device such as the high-voltage cutoff section 31 of the lighting lamp 3. The reason for this is that the deterioration detection device 4 is installed on the outer surface of the pillar body 21, and in the event of a lightning strike, there is a high possibility that an electric shock will be applied via the coil and damage the detection module 41. Therefore, the deterioration detection device 4 is configured so that four detection modules 41 are attached to the outer surface of the pillar body 21 with belts 42, making it easy to replace them in the event of a malfunction.
[0069] (1.2.4) Cover 5, the cover 5 is attached to the support 2. The cover 5 is attached to the support body 21. The cover 5 is attached to the lower end of the support body 21.
[0070] The cover 5 covers the lower end (exposed portion 212) of the pillar body 21. The cover 5 also covers the deterioration detection device 4 attached to the lower end of the pillar body 21. The cover 5 covers the detection module 41. The cover 5 also covers the acoustic device 47. That is, the detection module 41 and the acoustic device 47 are disposed inside the cover 5.
[0071] The cover 5 has weather resistance and is made of synthetic resin such as polycarbonate.
[0072] The cover 5 is shaped to cover the lower end of the pillar body 21 and the deterioration detection device 4. When viewed from above, the entire periphery of the exposed portion 212 at the lower end of the pillar body 21 is covered by the cover 5. When viewed from above, the entire deterioration detection device 4 is covered by the cover 5. The cover 5 surrounds the entire periphery of the pillar body 21.
[0073] As shown in FIG. 5, the cover 5 has a cover main body 51 and an attachment portion 52.
[0074] The cover body 51 is, for example, a hollow frustum shape with a lower surface area larger than the upper surface area, specifically a hollow frustum shape. The cover body 51 is open at the upper and lower surfaces, and is attached to the outer circumferential surface of the support body 21 with the support body 21 penetrating the upper and lower surfaces.
[0075] The mounting portion 52 is annular. The mounting portion 52 is provided at the upper end of the cover body 51. The mounting portion 52 is formed integrally with the cover body 51. The mounting portion 52 is a portion for mounting the cover 5 to the support body 21 by a fastener 53. The fastener 53 is disposed on the outer periphery of the mounting portion 52. The cover 5 is attached to the outer periphery of the support body 21 by tightening the fastener 53. The fastener 53 may be, for example, a band for tightening the mounting portion 52, or a screw for screwing into a screw hole formed in the mounting portion 52. The cover 5 may be attached to the support body 21 by a suitable method other than the fastener 53, such as adhesion or fitting into a protrusion formed on the outer periphery of the support body 21.
[0076] The cover 5 is attached to the support body 21 by, for example, attaching two halves obtained by dividing the cover 5 into left and right halves to the support body 21 and combining the two halves. Note that the shape of the cover 5 is not limited to a truncated cone shape, and may be a truncated pyramid shape or a shape other than a truncated cone shape, such as a dome shape or a hemisphere shape.
[0077] As described above, when attached to the pole body 21, the cover 5 covers the lower end (exposed portion 212) of the pole body 21 and the deterioration detection device 4. This makes it possible to prevent the lower end of the pole body 21 and the deterioration detection device 4 from deteriorating (corroding) due to the influence of rainwater, animal urine, snow-melting agents, seawater at the beach, etc.
[0078] The outdoor lighting device 1 of this embodiment further includes an auxiliary cover 59, as shown in Fig. 5. The auxiliary cover 59 is shaped like a canopy that is inclined downward and outward. The auxiliary cover 59 is attached to the pole body 21 inside the cover 5. The auxiliary cover 59 is provided around the entire periphery of the pole body 21 in the outer circumferential direction. The auxiliary cover 59 is provided above the deterioration detection device 4 (the detection module 41 and the audio device 47).
[0079] Furthermore, the cover body 51 is formed with one or more (here, two) drainage holes 54. An eave-shaped inclined portion 55 is provided on the inner surface of the cover body 51. The lower end of the inclined portion 55 is connected to the lower edge portion of the drainage hole 54. The inclined portion 55 is located below the auxiliary cover 59. When viewed from above, the outer end of the auxiliary cover 59 overlaps with the inclined portion 55.
[0080] Liquid (rainwater, urine, etc.) that seeps into the inside of the cover 5 from between the pillar body 21 and the mounting part 52 passes through the upper surface of the auxiliary cover 59 and the upper surface of the inclined part 55, and is drained to the outside of the cover 5 through the drainage hole 54. This prevents, for example, rainwater from reaching the deterioration detection device 4 even if it seeps into the inside of the cover 5 along the outer surface of the pillar body 21, and as a result, deterioration of the deterioration detection device 4 is prevented.
[0081] The cover 5 is attached to the support body 21 so that a gap G1 is provided between the bottom end of the cover 5 and the ground 109 (see FIG. 5). This allows sound from the acoustic device 47 to be emitted to the outside of the cover 5 through the gap G1.
[0082] In addition, there is a gap G1 between the bottom end of the cover 5 and the ground 109, and the cover body 51 is formed with a drainage hole 54, so that heat inside the cover 5 can easily escape to the outside through the gap G1 and the drainage hole 54. This prevents the inside of the cover 5 from becoming too hot due to solar heat or the like, and prevents deterioration of the deterioration detection device 4.
[0083] (1.2.5) Surveillance Cameras 3, the surveillance camera 6 is held by the pole 2 on the side of the upper end of the pole body 21. The surveillance camera 6 is held by an arm 22 of the pole 2.
[0084] As shown in FIG. 4, the surveillance camera 6 includes an imaging unit 61, a control unit 62, a memory 63, a short-range communication unit (hereinafter also referred to as the "third short-range communication unit") 64, a long-range communication unit 65, and a housing 60 (see FIG. 3).
[0085] The surveillance camera 6 is supplied with operating power from the first power supply circuit 32 of the illuminating lamp 3 .
[0086] The imaging unit 61 captures an image of the imaging range R2 (see FIG. 3). The imaging unit 61 generates image data of an image (video) captured in the imaging range R2. The imaging unit 61 is configured using, for example, a CCD (Charge Coupled Device) image sensor, a CMOS (Complementary Metal Oxide Semiconductor) image sensor, or the like. The imaging unit 61 has an imaging range R2 below the arm 22. The imaging range R2 of the imaging unit 61 includes the area where the surveillance mark 7 is located.
[0087] The memory 63 is connected to the control unit 62. The memory 63 includes one or more storage devices. The memory 63 is used to store various information such as information used by the control unit 62. The control unit 62 controls the operation of the imaging unit 61.
[0088] The third short-range communication unit 64 is a communication interface. The third short-range communication unit 64 is connected to the control unit 62. The third short-range communication unit 64 has a function of communicating with the first short-range communication unit 36 of the illumination lamp 3. The third short-range communication unit 64 has a function of communicating with the second short-range communication unit 46 of the deterioration detection device 4. The third short-range communication unit 64 has a function of communicating with the fourth short-range communication unit 88 of the charging device 8.
[0089] The long distance communication unit 65 is a communication interface. The long distance communication unit 65 is connectable to a communication network 99 and has a function of communicating through the communication network 99. The long distance communication unit 65 communicates with the long distance communication unit 91 of the management device 9 via the communication network 99.
[0090] The housing 60 holds an imaging unit 61 , a control unit 62 , a memory 63 , a third short-range communication unit 64 , and a long-range communication unit 65 .
[0091] The housing 60 is held by the support 2 near the upper end of the support 2. The housing 60 is held by the arm 22 of the support 2. The housing 60 is held by the arm 22 with the imaging range R2 of the imaging section 61 facing downward.
[0092] The surveillance camera 6 transmits image data of the image (video) captured by the imaging unit 61 to the management device 9 via the long-distance communication unit 65. A user of the management device 9 can view the image captured by the imaging unit 61 on the presentation unit 95 (image display device) of the management device 9.
[0093] Such images (video) from the surveillance camera 6 are used by the user of the management device 9 to determine whether or not it is acceptable to have the deterioration detection device 4 perform a deterioration detection operation.
[0094] As described above, the deterioration detection device 4 performs the deterioration detection operation in response to an instruction from the user of the management device 9. However, for example, if the pole 2 is shaking due to strong winds or the pole 2 is shaking due to vibrations caused by road construction near the outdoor lighting device 1, this may affect the determination of the deterioration of the pole body 21 by the deterioration detection device 4. Since the management device 9 is installed away from the outdoor lighting device 1, the user of the management device 9 cannot directly know the situation of the installation location of the outdoor lighting device 1. Therefore, in the outdoor lighting system 10 of this embodiment, image data of the image (video) of the surveillance camera 6 is transmitted to the management device 9, so that the user of the management device 9 can remotely know the situation of the installation location of the outdoor lighting device 1 (whether the pole 2 is shaking or vibrating, etc.). This allows the user of the management device 9 to operate the deterioration detection device 4 at an appropriate timing, that is, at a timing when the pole 2 is not shaking or vibrating, and allows the inspection of the deterioration degree of the pole 2 to be performed at an appropriate timing.
[0095] 3, the outdoor lighting device 1 may further include a wind monitoring unit 79 arranged within the imaging range R2 of the imaging unit 61 of the surveillance camera 6. The wind monitoring unit 79 is a device that indicates the strength of the wind at the location where the outdoor lighting device 1 is installed.
[0096] The wind monitoring unit 79 may be any device that enables the user of the management device 9 to determine, based on the image from the surveillance camera 6, whether the wind strength at the installation location is strong enough to operate the deterioration detection device 4 (i.e., whether the wind strength is strong enough to shake the support pole 2).
[0097] The wind monitoring unit 79 may be a device that can detect the wind strength at the installation location using an objective numerical value, or may be a device that allows a user of the management device 9 to subjectively judge the wind strength at the installation location from the image of the monitoring camera 6. The wind monitoring unit 79 may be, for example, an anemometer, a device that rotates due to the wind, such as a rotating blade (windmill), or a windsock that flutters in the wind.
[0098] In this embodiment, the wind monitoring unit 79 is a wind turbine attached to the pole body 21. The wind monitoring unit 79 is attached to the pole body 21 at a height of about 2.5 meters above the ground 109, for example.
[0099] Even without the wind monitoring unit 79, the user of the management device 9 can determine whether or not the pole 2 is shaking or vibrating from the video of the surveillance camera 6. For example, if the pole 2 is shaking or vibrating due to a rainstorm, a suspicious person hitting the pole 2, construction work being carried out nearby, or other reasons, the surveillance camera 6 held by the arm 22 of the pole 2 will shake. Therefore, for example, the pole body 21 and the surveillance mark 7 captured within the imaging range R2 will also shake and move. Therefore, the user of the management device 9 can determine whether or not the pole 2 is shaking or vibrating by checking the video of the surveillance camera 6.
[0100] (1.2.6) Surveillance Mark The monitoring mark 7 is disposed within the imaging range R2 of the imaging section 61 of the monitoring camera 6. The monitoring mark 7 is for monitoring whether or not the pillar body 21 is inclined relative to the vertical direction.
[0101] As shown in Fig. 6, the surveillance mark 7 is provided on the outer surface of the cover body 51 of the cover 5. In Fig. 6, the surveillance mark 7 is hatched with dots. The surveillance mark 7 is provided below the arm 22 on the outer surface of the cover body 51. Therefore, the surveillance mark 7 is disposed on the same side as the surveillance camera 6 with respect to the pillar body 21 as a reference. The surveillance mark 7 is provided on a portion of the cover 5 on the same side as the arm 22 with respect to the pillar body 21 as a reference when viewed from above (see Fig. 3).
[0102] As described above, the cover body 51 has a frustum shape with the area of the lower surface being larger than the area of the upper surface. Therefore, the outer surface of the cover body 51 has an inclined surface with the upper portion being closer to the support body 21 and the lower portion being farther away from the support body 21. By providing the surveillance mark 7 on such an inclined surface, it becomes easier to photograph and monitor the surveillance mark 7 with the surveillance camera 6.
[0103] In other words, if the surveillance mark 7 is formed on the side surface of the pillar body 21 facing the surveillance camera 6, and the surveillance mark 7 is provided on an inclined surface with the upper part close to the pillar body 21 and the lower part away from the pillar body 21, the surveillance mark 7 faces the surveillance camera 6. This makes it easier for the surveillance camera 6 to photograph and monitor the surveillance mark 7.
[0104] In this embodiment, the surveillance mark 7 is a symbol marked on the outer surface of the cover body 51 in a color different from that of other parts of the cover body 51. The surveillance mark 7 is, for example, a circular ring shape as shown in Fig. 6. The shape of the surveillance mark 7 is not limited to a circle, and may be any shape that is easy to monitor with the surveillance camera 6, such as a polygonal shape, an ellipse, a star shape, a cross mark, a sector shape, or a combination of multiple figures. The surveillance mark 7 may also be a three-dimensional shape that protrudes from or is recessed from the cover body 51 of the cover 5.
[0105] 6, the monitoring mark 7 is provided on the outer surface of the cover body 51 at a position that does not overlap with the drainage hole 54 in the vertical direction. This makes it difficult for liquid discharged from the drainage hole 54 to reach the monitoring mark 7, making it possible to prevent deterioration (dirt) of the monitoring mark 7.
[0106] As described above, the surveillance mark 7 can be used by a user of the management device 9 to determine whether or not the pole 2 is shaking based on the image from the surveillance camera 6.
[0107] Here, in the outdoor lighting device 1 of this embodiment, the monitoring mark 7 is used not only to judge whether the pole 2 is shaking, but also to monitor whether the pole body 21 is tilted with respect to the vertical direction. For example, the pole 2 may be tilted (bent) from when it is newly installed (initial state) due to contact with the pole 2 by a car or the influence of a strong wind. Therefore, in the outdoor lighting device 1 of this embodiment, the monitoring mark 7 is periodically monitored by the monitoring camera 6 to judge whether the pole 2 is tilted (bent).
[0108] That is, if the pillar body 21 is not swinging and has no inclination, the position of the surveillance mark 7 within the imaging range R2 (coordinates within the imaging range R2; see FIG. 7) should remain unchanged.
[0109] On the other hand, when the support body 21 is tilted from the initial state due to, for example, contact with an automobile, the position of the surveillance mark 7 in the imaging range R2 (coordinates in the imaging range R2) moves from the position in the initial state. Therefore, for example, the control unit 62 of the surveillance camera 6 registers the coordinate position of the surveillance mark 7 in the initial state as fixed point information (reference coordinate position) in, for example, the memory 63 of the surveillance camera 6, and takes an image with the surveillance camera 6 to compare the coordinate position of the surveillance mark 7 with the reference coordinate position. This makes it possible to detect the tilt of the support body 21 from the vertical direction. The surveillance camera 6 performs such fixed point surveillance operation periodically (for example, every hour). FIG. 7 is a diagram showing the imaging range R2 of the imaging unit 61 and the surveillance mark 7 reflected in the imaging range R2. In the example of FIG. 7, the surveillance mark 7 is located on the negative side of the X coordinate and near the 0 point of the Y coordinate. The coordinate position (reference coordinate position) of this surveillance mark 7 is registered in the memory 63 as fixed point information.
[0110] If the support pole 2 sways due to strong winds, earthquakes, or the like while the surveillance camera 6 is capturing an image of the imaging range R2 for fixed-point surveillance operation, the coordinate position of the surveillance mark 7 in the captured image may shift from the reference coordinate position. Therefore, the control unit 62 may acquire the coordinate position of the surveillance mark 7 in chronological order, and determine whether the shift in the coordinate position of the surveillance mark 7 is due to a permanent or temporary tilt of the support pole 2. The control unit 62 may determine that there is an abnormality (tilt) in the support pole 2 when the tilt of the support pole 2 is permanent.
[0111] One example of a method for acquiring the coordinate position of surveillance mark 7 in time series is to acquire the coordinate position of surveillance mark 7 from each of multiple images captured during multiple fixed-point monitoring operations. Another example of a method for acquiring the coordinate position of surveillance mark 7 in time series is to acquire the coordinate position of surveillance mark 7 from each of multiple images included in a video captured continuously for a predetermined period of time during a single fixed-point monitoring operation.
[0112] (1.2.7) Charging device The charging device 8 is a device for charging an external device. The charging device 8 is a device for charging an electric vehicle (EV), for example. As shown in FIG. 3, the charging device 8 is held by a pole body 21.
[0113] As shown in FIG. 2, a road 100 on which the outdoor lighting device 1 is installed has a parking space 104 set up for users (users) of the charging device 8 to park their cars.
[0114] 3, 4 and 8, the charging device 8 includes an outlet 81, an operation unit 82, a display unit 83, a high-voltage cutoff unit 84, a power circuit (hereinafter also referred to as a "third power circuit") 85, a control unit 86, a memory 87, a short-range communication unit (hereinafter also referred to as a "fourth short-range communication unit") 88, a sound generator 89, and a housing 80. The charging device 8 is connected to a commercial power system AC1 by, for example, a power cable L3, and is supplied with AC power from the power system AC1.
[0115] The outlet 81 is a typical charging outlet to which a charging plug for charging an electric vehicle can be detachably connected.
[0116] The operation unit 82 accepts operations from a user of the charging device 8. The operation unit 82 accepts a charging instruction from the user of the charging device 8 to charge an external device (electric vehicle) connected to the outlet 81. The operation unit 82 has, for example, a touch pad and / or one or more buttons. Furthermore, instead of / in addition to the operation unit 82, the charging device 8 may be provided with a voice input device that accepts instructions from the user.
[0117] The display unit 83 presents various information to a user of the charging device 8. The display unit 83 includes an image display device. The image display device is, for example, a thin display device such as a liquid crystal display or an organic EL display. The touch pad of the operation unit 82 and the image display device of the display unit 83 may form a touch panel.
[0118] High voltage cut-off unit 84 is provided in front of third power supply circuit 85. High voltage cut-off unit 84 is, for example, a lightning arrester (arrester). The lightning arrester is, for example, a varistor (non-linear resistance element). High voltage cut-off unit 84 cuts off the electric circuit when high voltage is applied, preventing overcurrent from flowing into control unit 86 and outlet 81. Charging device 8 is attached to a relatively tall support pole 2. Therefore, high voltage cut-off unit 84 is provided as a measure against lightning strikes.
[0119] The third power supply circuit 85 includes, for example, a rectifier circuit, a converter circuit (AC / DC converter, DC / DC converter), etc. The third power supply circuit 85 converts AC power supplied from the power system AC1 via the power cable L3 into operating power for operating the control unit 86, and supplies the operating power to the control unit 86. The third power supply circuit 85 also includes a charging circuit 851. The charging circuit 851 is operated by the control unit 86 to convert the AC power supplied from the power system AC1 via the power cable L3 into charging power for charging output from the outlet 81, and outputs the charging power to the outlet 81.
[0120] The fourth short-range communication unit 88 is a communication interface. The fourth short-range communication unit 88 is connected to the control unit 86. The fourth short-range communication unit 88 has a function of communicating with the third short-range communication unit 64 of the surveillance camera 6. The fourth short-range communication unit 88 communicates with the third short-range communication unit 64 wirelessly. The fourth short-range communication unit 88 may include a wireless communication interface that complies with standards such as Wi-SUN (registered trademark), Bluetooth (registered trademark), and ZigBee (registered trademark). The fourth short-range communication unit 88 may communicate with the third short-range communication unit 64 in a wired manner.
[0121] The memory 87 is connected to the control unit 86. The memory 87 includes one or more storage devices. The memory 87 is used to store various information, such as information used by the control unit 86.
[0122] The control unit 86 controls the operation of the charging circuit 851 and the display unit 83. The control unit 86 controls the operation of the charging circuit 851 and the display unit 83 based on a user's operation received by the operation unit 82, information stored in the memory 87, and the like.
[0123] The sound output unit 89 includes, for example, a speaker. The sound output unit 89 generates a sound or voice under the control of the control unit 86. The sound output from the sound output unit 89 may include a beep sound stored in the memory 87. The sound output from the sound output unit 89 may include an artificial voice stored in the memory 87.
[0124] The housing 80 holds an outlet 81, an operation unit 82, a display unit 83, a high voltage cut-off unit 84, a third power supply circuit 85, a control unit 86, a memory 87, a fourth short-range communication unit 88, and a sound generation unit 89. As shown in FIG. 8 , the housing 80 holds the outlet 81, the operation unit 82, and the display unit 83 such that the outlet 81, the operation unit 82, and the display unit 83 are exposed to the outside of the housing 80.
[0125] The housing 80 is held by the pole body 21. The housing 80 is held on the pole body 21 at a height between the arm 22 and the cover 5. The housing 80 is held at a height within the reach of a typical user of the charging device 8. When viewed from above, the housing 80 is disposed on the opposite side of the arm 22 with the pole body 21 as a reference. When viewed from above, the housing 80 is disposed on the opposite side of the monitoring mark 7 with the pole body 21 as a reference. That is, when viewed from above, the charging device 8 is disposed on the opposite side of the monitoring mark 7 with the pole body 21 as a reference (see FIG. 3). Also, the display unit 83 is disposed on the opposite side of the monitoring mark 7 with the pole body 21 as a reference, when viewed from above.
[0126] If the housing 80 is arranged on the same side as the surveillance mark 7 with respect to the pillar body 21 as a reference, there is a possibility that the housing 80 will interfere with the surveillance of the surveillance mark 7 by the surveillance camera 6. By arranging the housing 80 on the opposite side to the surveillance mark 7 with respect to the pillar body 21 as viewed from above, the housing 80 is less likely to interfere with the surveillance camera 6 capturing an image of the surveillance mark 7.
[0127] Furthermore, if display unit 83 is located on the same side as surveillance mark 7 with respect to pillar body 21 as a reference, there is a possibility that light emitted from display unit 83 will interfere with surveillance of surveillance mark 7 by surveillance camera 6. By locating display unit 83 on the opposite side to surveillance mark 7 with respect to pillar body 21 as viewed from above, light emitted from display unit 83 is less likely to interfere with surveillance camera 6 capturing an image of surveillance mark 7.
[0128] The power cable L3 connects between the charging device 8 and the power system AC1. The power cable L3 includes a pair of electric wires. A first end of the power cable L3 is connected to the charging device 8 (high voltage cut-off unit 84). The power cable L3 extends downward along the outer circumferential surface of the pole body 21. A second end of the power cable L3 is connected to the power system AC1 outside the pole 2.
[0129] The charging device 8 may prohibit the charging operation when there is a possibility of lightning occurring around the installation location of the pole 2 on which the charging device 8 is installed.
[0130] For example, a user of the management device 9 (or the management device 9 automatically refers to weather information) causes the management device 9 to transmit a charging prohibition command to outdoor lighting devices 1 in areas where a thunderstorm warning has been issued. The charging device 8 of the outdoor lighting device 1 that has received the charging prohibition command causes the display unit 83 to display, for example, a character string "Thunderstorm warning in effect, charging not permitted", indicating that charging is prohibited due to thunder. Furthermore, the charging device 8 of the outdoor lighting device 1 that has received the charging prohibition command does not perform charging even if it receives a charging instruction from a user. When the control unit 86 of the charging device 8 receives a charging instruction from a user while it has received the charging prohibition command, it may cause the sound output unit 89 to output a voice (artificial voice) indicating that charging is prohibited because a thunderstorm warning has been issued.
[0131] (1.3) Operation An example of the operation of the outdoor lighting system 10 will now be described with reference to FIGS.
[0132] FIG. 9 is a flowchart showing the operation of the outdoor lighting device 1.
[0133] When the outdoor lighting device 1 is installed outdoors and turned on, and the surveillance camera 6 is started up (turned on) (ST1), the coordinate position of the surveillance mark 7 in the image captured by the imaging unit 61 of the surveillance camera 6 is registered as fixed point information (reference coordinate position) (ST2).
[0134] Thereafter, the outdoor lighting device 1 performs a normal operation (ST3). During the normal operation, the outdoor lighting device 1 also performs a fixed point monitoring operation (ST4), a deterioration detection operation (ST5), and a charging operation (ST6).
[0135] (1.3.1) Normal operation The normal operation of the outdoor lighting device 1 will be described with reference to FIG.
[0136] In normal operation, the surveillance camera 6 captures an image of the imaging range R2 with the imaging unit 61, and transmits image data of the captured image (video) to the management device 9 (ST101). That is, the surveillance camera 6 functions as a general surveillance camera.
[0137] In addition, in normal operation, the illuminating lamp 3 of the outdoor lighting device 1 operates (turns on / off) the illumination unit 34 in accordance with the brightness of the surrounding environment.
[0138] Specifically, the control unit 33 of the illumination lamp 3 acquires the illuminance measured by the illuminance sensor 35 (ST102), and determines whether the acquired illuminance is equal to or greater than a first threshold value Th1 (ST103). The first threshold value Th1 is an illuminance value that serves as a reference for switching the illumination unit 34 from off to on.
[0139] If the acquired illuminance is less than the first threshold value Th1 (ST103: No), the control unit 33 of the illuminating lamp 3 performs a lighting operation to turn on the illuminating unit 34 (ST104). The control unit 33 also transmits information indicating that the lighting operation has been performed to the control unit 62 of the surveillance camera 6 via the first short-range communication unit 36 (ST105). The control unit 62 of the surveillance camera 6 stores the latest operating state (lit) of the illuminating lamp 3 in the memory 63. The lighting unit 34 is turned on by the lighting operation (ST106).
[0140] If the acquired illuminance is equal to or greater than the first threshold value Th1 (ST103: Yes), the control unit 33 of the illuminating lamp 3 judges whether the acquired illuminance is equal to or greater than the second threshold value Th2 (ST107). The second threshold value Th2 is an illuminance value that serves as a reference for switching the illumination unit 34 from on to off. The second threshold value Th2 is a value greater than the first threshold value Th1. The second threshold value Th2 is a value greater than the illuminance when, for example, the illumination area R1 is illuminated by only the illumination unit 34 in the middle of the night.
[0141] When the acquired illuminance is less than the second threshold value Th2 (ST107: No), the control unit 33 of the illuminating lamp 3 continues the operation of the illuminating unit .
[0142] If the acquired illuminance is equal to or greater than the second threshold value Th2 (ST107: Yes), the control unit 33 of the illuminating light 3 performs a turn-off operation to turn off the illuminating unit 34 (ST108). The control unit 33 also transmits information indicating that the turn-off operation has been performed to the control unit 62 of the surveillance camera 6 via the first short-range communication unit 36 (ST109). The control unit 62 of the surveillance camera 6 stores the latest operating state (off) of the illuminating light 3 in the memory 63. The illuminating unit 34 is turned off by the turn-off operation (ST110).
[0143] Meanwhile, the management device 9 receives images (video) from the surveillance camera 6 via the long-distance communication unit 91. As described above, the management device 9 manages a plurality of outdoor lighting devices 1, and therefore receives images from the surveillance cameras 6 of the plurality of outdoor lighting devices 1. The management device 9 displays the received images from the surveillance camera 6 on the presentation unit 95 (image display device).
[0144] The user of the management device 9 checks the images (video) of the surveillance camera 6. If the user of the management device 9 finds an image of concern, the user may use the input unit 94 (operation unit) to transmit appropriate instructions to the control unit 44 of the outdoor lighting device 1 equipped with the corresponding surveillance camera 6, and cause the audio device 47 to issue information, an alarm, or the like.
[0145] For example, when a user (monitoring staff) of the management device 9 finds an abnormal condition near the pillar 2 while checking images from the surveillance camera 6, the user can use the input unit 94 (operation unit) to transmit appropriate instructions to the control unit 44 of the outdoor lighting device 1 equipped with the relevant surveillance camera 6, causing the audio device 47 to issue information, an alarm, or the like. Abnormal situations near the pillar 2 are not particularly limited, but include, for example, the occurrence of a fire, an accident, or a commotion.
[0146] In addition, when there is a garbage dump near the support 2 and crows, cats, dogs, etc. are littering the garbage at that place, the sound device 47 can emit sounds of crows, cats, dogs, etc. to suppress damage from birds and animals.
[0147] The outdoor lighting device 1 can automatically recognize crows, cats, dogs, etc. from the images captured by the surveillance camera 6 without communicating with the management device 9, and automatically emit onomatopoeic sounds for crows, cats, dogs, etc. from the audio device 47, thereby suppressing damage caused by birds and animals.
[0148] (1.3.2) Fixed-point monitoring operation The fixed-point monitoring operation of the surveillance camera 6 of the outdoor lighting device 1 will be described with reference to the flowchart of Fig. 11. As described above, the surveillance camera 6 periodically performs fixed-point monitoring operation. The surveillance camera 6 performs fixed-point monitoring operation multiple times in a day. The surveillance camera 6 performs fixed-point monitoring operation, for example, every hour.
[0149] When it is time to perform fixed-point monitoring operation (ST201: Yes), the control unit 62 of the surveillance camera 6 judges whether the latest operation (operation state) of the control unit 33 of the illumination light 3 acquired from the illumination light 3 is a turn-off operation (ST202). Specifically, the control unit 62 acquires from the memory 63 the latest operation (turn-on operation or turn-off operation) of the illumination light 3 stored in the memory 63.
[0150] If the most recent operation is a lights-off operation (ST202: Yes), the control unit 62 of the surveillance camera 6 uses the most recent image captured by the imaging unit 61 to determine the coordinate position of the surveillance mark 7 within the imaging range R2, and compares the determined coordinate position with a reference coordinate position (ST203).
[0151] If the coordinate position of the surveillance mark 7 in the latest image approximately matches the reference coordinate position (ST203: Yes), the control unit 62 determines that the surveillance mark 7 is normal (ST204) and ends the fixed-point surveillance operation without issuing an alarm or performing any other processing.
[0152] On the other hand, if the coordinate position of the surveillance mark 7 in the latest image is shifted from the reference coordinate position, or if the surveillance mark 7 cannot be detected in the latest image (ST203: No), the control unit 62 determines that there is an abnormality in the pillar 2, for example, that the pillar 2 may be tilted (ST205), and transmits information indicating the abnormality in the pillar 2 to the management device 9 (ST206).
[0153] Even if the most recent operation is not a turn-off operation, i.e., if the most recent operation (operating state) is a turn-on operation (ST202: No), the control unit 62 of the surveillance camera 6 uses the most recent image captured by the imaging unit 61 to determine the coordinate position of the surveillance mark 7 within the imaging range R2, and compares the determined coordinate position with the reference coordinate position (ST207).
[0154] If the coordinate position of the surveillance mark 7 in the latest image approximately matches the reference coordinate position (ST207: Yes), the control unit 62 determines that the surveillance mark 7 is normal (ST208) and ends the fixed point surveillance operation without issuing any particular alarm.
[0155] On the other hand, if the monitoring mark 7 cannot be detected at the reference coordinate position in the latest image, the control unit 62 determines that there is an abnormality in the outdoor lighting device 1 (ST209). Here, the case where the latest operation is a lighting operation means that, for example, the surroundings are dark because the current time is nighttime, and the lighting unit 34 is turned on. Therefore, the reason why the monitoring mark 7 cannot be detected at the reference coordinate position may be a malfunction (failure to light) of the lighting unit 34 of the illuminating lamp 3, in addition to the tilt of the pole 2. Therefore, the control unit 62 transmits information indicating an abnormality in the lighting unit 34 to the management device 9 (ST210). Of course, the control unit 62 may transmit information indicating that at least one of an abnormality in the pole 2 and an abnormality in the lighting unit 34 has occurred to the management device 9. Thereafter, the control unit 62 may cause the audio device 47 of the deterioration detection device 4 to emit an alarm sound in response to an alarm instruction from the management device 9 acquired via the long-distance communication unit 65.
[0156] When the management device 9 receives information about an abnormality in the pole 2 (ST206) or the lighting unit 34 (ST210) via the long-distance communication unit 91, the management device 9 presents the abnormality in the pole 2 or the lighting unit 34 by the presentation unit 95. Specifically, the abnormality is notified by an image from the image display device or a sound from the sound output device. The management device 9 also stores information about the abnormality in the pole 2 or the lighting unit 34 in the memory 93 in association with the identification information of the outdoor lighting device 1.
[0157] When information about an abnormality in the support pole 2 or the lighting unit 34 is presented, the user (monitor) of the management device 9 or an inspector contacted by the monitor can go to the installation location of the outdoor lighting device 1 and inspect / repair / replace, etc. the outdoor lighting device 1.
[0158] Furthermore, the user of the management device 9 may use the audio device 47 of the deterioration detection device 4 or the like to notify people in the neighborhood that a defect has occurred in the pole 2 or the lighting unit 34, thereby creating a sense of security. In this case, the user of the management device 9 may appropriately operate the input unit 94, and the instruction content may be transmitted from the long-distance communication unit 91 to the control unit 44 via the long-distance communication unit 65 and the short-distance communication units 64 and 46 of the outdoor lighting device 1.
[0159] (1.3.3) Degradation detection operation The deterioration detection operation of the deterioration detection device 4 of the outdoor lighting device 1 will be described with reference to Fig. 12 and Fig. 13. Here, the operation of the management device 9 when the deterioration detection device 4 of the outdoor lighting device 1 performs the deterioration detection operation will also be described. Fig. 12 is a flowchart of the operation of the management device 9, and Fig. 13 is a flowchart of the operation of the deterioration detection device 4.
[0160] As described above, the management device 9 manages a plurality of outdoor lighting devices 1. The management device 9 manages a large number of outdoor lighting devices 1 arranged in many locations over a wide area. The management device 9 periodically detects deterioration of the outdoor lighting devices 1 using the deterioration detection device 4 provided in each of the outdoor lighting devices 1.
[0161] Here, periodic deterioration detection of the outdoor lighting device 1 by the deterioration detection device 4 is performed to detect a decrease in strength of the support 2 due to corrosion and to prevent the support 2 from tilting or collapsing. Note that corrosion of the support 2 does not progress suddenly, and as described above, the tilt of the support 2 is monitored periodically (for example, every hour) by the monitoring camera 6. Therefore, deterioration may be detected by the deterioration detection device 4, for example, about once a month.
[0162] 12, when it is time to perform a deterioration inspection by the deterioration detection device 4, the user of the management device 9 uses the input unit 94 to cause the image display device to display a list of the outdoor lighting devices 1 for which the deterioration inspection is to be performed (ST301). When it is time to perform the deterioration inspection, the management device 9 may notify the user that it is time to perform the deterioration inspection by, for example, displaying / sounding an alarm. The user selects the outdoor lighting devices 1 for which the deterioration inspection is to be performed from the displayed list (ST302).
[0163] When an outdoor lighting device 1 for which a deterioration inspection is to be performed is selected, an image captured by a security camera 6 of the selected outdoor lighting device 1 is displayed on the image display device of the management device 9 (ST303).
[0164] The user of the management device 9 checks the displayed video from the security camera 6 and determines whether or not to carry out a deterioration inspection on the selected outdoor lighting device 1.
[0165] That is, because the deterioration inspection of the pole 2 of the outdoor lighting device 1 due to corrosion involves handling minute ultrasonic signals, it is required to carry out the inspection while taking into full consideration the environment around the pole 2. For example, if construction work involving large vibrations is being carried out nearby, if there is a rainstorm, or if a suspicious person is hitting the pole 2, it is expected that the image captured by the surveillance camera 6 will also be shaking. In such a case, it is expected that the pole 2 will also be shaking. Since the shaking (vibration) of the pole 2 affects the accuracy of the deterioration detection device 4 in detecting deterioration, the pole 2 is not inspected in such a case.
[0166] The presence or absence of strong winds strong enough to shake the pole 2 may be confirmed from the image of the wind monitoring unit 79 captured by the surveillance camera 6. The wind monitoring unit 79 is equipped with multiple rotating blades, and the presence or absence and strength of wind can be confirmed from the rotation status of the rotating blades. The state of the surveillance mark 7 captured by the surveillance camera 6 can also be used to confirm the environment around the pole 2. For example, if inadvertent vibrations are transmitted to the pole 2, it is expected that the surveillance mark 7 will also vibrate slightly. Therefore, the user of the management device 9 can determine the vibration and swaying of the pole 2 using the image of the surveillance mark 7 captured by the surveillance camera 6.
[0167] The user of management device 9 checks these conditions on the image on the image display device of management device 9, and if it determines that there is no problem, transmits an inspection start instruction to outdoor lighting device 1 (ST304).
[0168] Explaining with reference to FIG. 13, when the deterioration detection device 4 receives an inspection start instruction from the management device 9 (ST401: Yes), it performs a deterioration detection operation to detect deterioration of the lower end portion of the pillar main body 21.
[0169] As described above, the deterioration detection device 4 includes a plurality of (here, four) detection modules 41. Hereinafter, the four detection modules 41 will be referred to as a first detection module 41 to a fourth detection module 41 to be distinguished from one another.
[0170] When the control unit 44 of the deterioration detection device 4 receives an inspection start instruction from the management device 9, it operates the first detection module 41 (ST402) and stores the first detection data indicating the detection result in the memory 45 (ST403). Then, the control unit 44 operates the second detection module 41 (ST404) and stores the second detection data indicating the detection result in the memory 45 (ST405). Then, the control unit 44 operates the third detection module 41 (ST406) and stores the third detection data indicating the detection result in the memory 45 (ST407). Then, the control unit 44 operates the fourth detection module 41 (ST408) and stores the fourth detection data indicating the detection result in the memory 45 (ST409).
[0171] The control unit 44 performs a deterioration judgment of the pillar 2 (pillar main body 21) using the first detection data to the fourth detection data (ST410), and transmits information indicating the judgment result to the management device 9 (ST411). The judgment result may be a "normal judgment" indicating that the pillar 2 is normal, or a "corrosion deterioration judgment" indicating that the pillar 2 is corroded. The information indicating the judgment result is transmitted from the long distance communication unit 65 to the long distance communication unit 91 of the management device 9 via the short distance communication units 46, 64.
[0172] Returning to FIG. 12, the management device 9 receives the judgment result from the outdoor lighting device 1 (ST305). The management device 9 distinguishes whether the received judgment result is a "normal judgment" indicating that the support 2 is normal, or a "corrosion deterioration judgment" indicating that the support 2 is corroded (ST306). If the judgment is normal (ST306: Yes), the management device 9 stores the judgment result (normal judgment) and the date and time when the deterioration inspection was performed in the memory 93 in association with the identification information of the outdoor lighting device 1 (ST307). If the judgment is not normal, that is, if the judgment is corrosion deterioration (ST306: No), the management device 9 displays an alarm display on the image display device of the presentation unit 95 and emits an alarm sound from the sound output device (ST308). In addition, the management device 9 stores the judgment result (corrosion deterioration judgment) and the date and time when the deterioration inspection was performed in association with the identification information of the outdoor lighting device 1 in the memory 93 (ST309).
[0173] When the deterioration inspection of one outdoor lighting device 1 is completed, the management device 9 displays a list of the outdoor lighting devices 1 on the image display device (ST311). If the user of the management device 9 wishes to perform a deterioration inspection of another outdoor lighting device 1, the user refers to the list, selects the next outdoor lighting device 1 (ST311: Yes), and performs the deterioration inspection.
[0174] For example, when the deterioration check is completed for all outdoor lighting devices 1 on the list, the user ends the check.
[0175] (1.3.4) Charging operation The operation of charging an external device (for example, a battery of an electric vehicle) by the charging device 8 (see FIG. 4) of the outdoor lighting device 1 will be described with reference to FIG.
[0176] For example, on the display unit 83 of the charging device 8, a charging guide display for charging via the outlet 81 is displayed.
[0177] When the user of the charging device 8 issues a charging instruction in accordance with the display contents of the display unit 83 (ST501: Yes), an information input display is displayed on the display unit 24, prompting the user to input payment information for paying the charging fee (ST502). The payment information may include, for example, the user's registration number, the user's credit card number, etc. The charging device 8 may be equipped with a device such as a card reader for accepting payment information.
[0178] When the user inputs payment information (ST503), the control unit 86 checks the connection of the charging cable to the outlet 81 (ST504), and operates the charging circuit 851 to start charging the external device (electric vehicle) via the charging cable (ST505). After the charging starts, when an end operation for ending the charging is accepted from the user (ST506: Yes), the control unit 86 ends the charging operation (ST507) and causes the display unit 83 to display the charging fee (ST508). Then, charging information including the charging fee, the charging amount, payment information, etc. is transmitted to the management device 9 (ST509). The charging information is transmitted from the long-distance communication unit 65 to the long-distance communication unit 91 of the management device 9 via the short-distance communication units 88 and 64.
[0179] The management device 9 receives the charging information via the long-distance communication unit 91. The management device 9 stores the received charging information in the memory 93, and performs appropriate processing such as communication with an external server.
[0180] (1.4) Advantages In the outdoor lighting system 10 of the present embodiment described above, the deterioration of the lower end of the pole body 21 of the outdoor lighting device 1 is detected by the deterioration detection device 4 without an inspector visiting the installation site of the outdoor lighting device 1, and the detection result is transmitted to the management device 9. This makes it possible to efficiently manage the outdoor lighting device 1. It also makes it possible to reduce the burden on the inspector. Furthermore, when an inspector visits the installation site to conduct an inspection, measures for traffic safety near the work site are required, but these are also unnecessary.
[0181] The outdoor lighting device 1 is also equipped with a surveillance camera 6. Such a surveillance camera 6 can not only monitor the periphery of the pole 2 under normal conditions, but also greatly contribute to the judgment of whether or not the deterioration detection device 4 should carry out a deterioration inspection.
[0182] That is, the inspection by the deterioration detection device 4 detects minute waves (ultrasound waves, etc.) that are transmitted through the support 2. For this reason, it is not preferable to perform the inspection when the support 2 is shaking due to wind or vibrations from nearby construction work, etc., as this may adversely affect the results. In contrast, in the outdoor lighting system 10 of this embodiment, it is possible to check whether or not vibrations are likely to be applied to the support 2 by checking the surrounding images captured by the surveillance camera 6, the images captured by the wind monitoring unit 79, the surveillance images of the surveillance mark 7, etc., and then to perform an inspection by the deterioration detection device 4. This allows for an appropriate inspection to be performed.
[0183] Moreover, it is possible to determine whether or not the inspection may be carried out without the need for an inspector to visit the installation location of the outdoor lighting device 1 to be inspected, which in practice significantly improves work efficiency.
[0184] In addition, since the surveillance camera 6 monitors the surveillance mark 7 at fixed points, it is possible to quickly detect the occurrence of a tilted state of the support pole 2. That is, the support pole 2 may become tilted due to, for example, contact with a car or the influence of a strong wind, but such a state cannot be detected by the deterioration detection device 4 because it is not caused by corrosion of the support pole 2. In contrast, in the outdoor lighting system 10 of this embodiment, when the support pole 2 tilts, the occurrence of the tilt can be detected immediately by the fixed point monitoring by the surveillance camera 6, and measures such as repairing the support pole 2 can be quickly taken.
[0185] (2) Variations The embodiments of the present disclosure are not limited to the above-described embodiments. The above-described embodiments can be modified in various ways depending on the design and the like as long as the object of the present disclosure can be achieved.
[0186] Furthermore, functions similar to those of the management device 9 of the outdoor lighting system 10 may be embodied as a management method, a (computer) program, or a non-transitory recording medium on which a program is recorded.
[0187] The management method according to one embodiment is a method for managing an outdoor lighting device 1. The outdoor lighting device 1 includes a pole 2, a luminaire 3, a surveillance camera 6, and a deterioration detection device 4. The pole 2 has a pole body 21 having an upper end and a lower end. The pole 2 is installed outdoors such that the tip (buried part 211) of the lower end of the pole body 21 is buried in the ground. The luminaire 3 is held by the pole 2 on the upper end side of the pole body 21. The surveillance camera 6 is held by the pole 2 on the upper end side of the pole body 21. The deterioration detection device 4 detects deterioration of the lower end of the pole body 21. The surveillance camera 6 transmits image data of an image captured by the surveillance camera 6 to the management device 9. The management method includes determining whether or not to operate the deterioration detection device 4 based on the image captured by the surveillance camera 6, causing the deterioration detection device 4 to perform a deterioration detection operation for detecting the presence or absence of deterioration of the lower end of the pole body 21, and receiving information indicating the result of the deterioration detection operation.
[0188] Modifications of the above embodiment are listed below. Hereinafter, the above embodiment may be referred to as a "basic example." The basic example and the modifications described below can be applied in appropriate combination.
[0189] The outdoor lighting system 10 in the present disclosure includes a computer system, for example, in the processing unit 92 of the management device 9. The computer system is mainly composed of a processor and a memory as hardware. The processor executes a program recorded in the memory of the computer system, thereby realizing the function of the processing unit 92 in the present disclosure. The program may be pre-recorded in the memory of the computer system, provided through an electric communication line, or provided by recording it in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). The integrated circuits such as IC or LSI referred to here are called by different names depending on the degree of integration, and include integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Furthermore, a field-programmable gate array (FPGA) that is programmed after the manufacture of the LSI, or a logic device that can reconfigure the connection relationship inside the LSI or reconfigure the circuit partition inside the LSI, can also be adopted as a processor. The electronic circuits may be integrated in one chip or distributed among multiple chips. The chips may be integrated in one device or distributed among multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Thus, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.
[0190] Furthermore, it is not essential for the management device 9 that multiple functions are concentrated in one housing. The components of the management device 9 may be distributed across multiple housings. Conversely, some of the functions of the management device 9 may be concentrated in one housing. Furthermore, at least some of the functions of the management device 9, such as at least some of the functions of the processing unit 92, may be realized by, for example, a server or a cloud (cloud computing).
[0191] (2.1) Variation 1 In the outdoor lighting device 1 of the basic example, the pole 2 is installed outdoors (sidewalk 101) with the tip (buried part 211) of the lower end of the pole body 21 buried in the ground, but the pole 2 is not limited to this.
[0192] In outdoor lighting device 1 of this modified example, post 2 is fixed to a concrete block 11 buried in the ground with bolts 12 and nuts 13, and is installed outdoors. That is, in outdoor lighting device 1 of this modified example, the lower end of post body 21 does not include buried portion 211, but only exposed portion 212.
[0193] In this modification, a metal fixture 14 is welded and fixed to the lower end of the pillar body 21. The fixture 14 is, for example, cylindrical with a flange 141 at the lower end and has four trapezoidal support parts 142 on the side. Then, bolts 12 are passed through through holes 143 provided at equal intervals of 90 degrees in four places of the flange 141 of the fixture 14, and nuts 13 are fastened to the upper parts of the bolts 12, so that the pillar 2 is fixed to the concrete block 11 and stands upright on the ground 109.
[0194] Even in the pillar 2 of this modified example, the deterioration detection device 4 can detect deterioration of the lower end portion (exposed portion 212) of the pillar body 21 of the pillar 2.
[0195] In the outdoor lighting device 1 of this modified example, the deterioration detection device 4 may include a detection module for detecting deterioration of the bolt 12.
[0196] The detection module for detecting the deterioration of the bolt 12 may include, for example, an ultrasonic vertical probe set on the top surface of the bolt 12. This detection module makes ultrasonic waves obliquely incident on the bolt 12 from the ultrasonic vertical probe to the bolt 12 so that the ultrasonic waves are reflected near the surface of the foundation (concrete block 11) where the thread groove of the bolt 12 is formed. Then, the corrosion state of the bolt 12 near the surface of the foundation can be diagnosed from the loss of peaks that appear for each thread of the reflected wave received by the ultrasonic vertical probe. That is, if the bolt 12 is healthy and free of corrosion, the ultrasonic waves reflected by the slope of the thread between each thread groove near the surface of the foundation are received by the ultrasonic vertical probe as oblique reflected waves, but if the bolt 12 is defective and corroded to the extent that the thread is damaged, the reflected waves are not received by the ultrasonic vertical probe. This makes it possible to detect the defective state of the bolt 12.
[0197] (2.2) Variation 2 The deterioration detection device 4 is not limited to a configuration that detects the occurrence of corrosion based on the length of detection time of the reflected ultrasonic wave. The deterioration detection device 4 may be configured to generate eddy currents by applying an AC magnetic field to the pillar body 21, and detect deterioration of the pillar body 21 based on the magnetic field generated by the eddy current. For example, the deterioration detection device 4 includes a magnetic probe having a coil and a magnetic sensor, a current source, a detector, and an analyzer. The coil applies an AC magnetic field to the lower end of the pillar body 21 to generate eddy currents. The magnetic sensor detects a response (magnetic field) from the pillar body 21 to the AC magnetic field applied by the coil. The current source supplies an AC current of a predetermined frequency to the coil. The detector detects an output signal from the magnetic sensor. The analyzer performs analysis using the output signal from the detector.
[0198] That is, an AC magnetic field is applied from the coil of the magnetic probe to the pillar body 21 to generate an eddy current in the pillar body 21, and the magnetic field generated by this eddy current is detected by a magnetic sensor and analyzed by an analyzer to detect deterioration of the pillar 2. That is, in this modified example, the thinner the plate thickness of the pillar body 21 is, that is, the greater the reduction in thickness due to corrosion, the more the signal attenuates, and this makes it possible to detect deterioration of the pillar body 21.
[0199] (2.3) Other Modifications In one variant, the outdoor lighting device 1 is not limited to a street lamp, but may be any lighting device that is installed outdoors and has a pole.
[0200] In one modified example, the support pillar 2 is not limited to being made of metal, but may be made of concrete. When the support pillar 2 is made of concrete, a device that detects corrosion of reinforcing bars inside the concrete can be used as the deterioration detection device 4. Alternatively, a device that detects vibrations propagating through the concrete can be used as the deterioration detection device 4.
[0201] In one modified example, the deterioration detection device 4 may detect deterioration of the pillar body 21 by applying a mechanical shock to the pillar body 21 and detecting an elastic wave propagating through the pillar body 21.
[0202] In one variant, the monitoring mark 7 may be provided at a location other than the cover 5, for example, on a portion of the support column body 21 exposed above the cover 5. The monitoring mark 7 may be provided on the support column 2 or the cover 5 via a support.
[0203] In one variant, the outdoor lighting device 1 may not include a charging device 8 .
[0204] In one variant, the long-distance communication unit 65 of the outdoor lighting device 1, which communicates with the long-distance communication unit 91 of the management device 9, may be provided in a device other than the surveillance camera 6, i.e., the illumination lamp 3, the deterioration detection device 4, the charging device 8, or an external communication device.
[0205] In one variant, at least some of the functions of the processing unit 92 of the management device 9 and / or at least some of the decisions made by the user of the management device 9, such as a decision as to whether or not to operate the deterioration detection device 4 based on an image from the surveillance camera 6, may be performed by a trained model.
[0206] In one modified example, at least some of the functions of the outdoor lighting device 1, for example, the function of the control unit 62 determining the deviation between the coordinate position of the surveillance mark 7 and a reference coordinate position during fixed-point surveillance operation, may be performed by a trained model.
[0207] (3) Description As is apparent from the above-described embodiment and modified examples, the present specification discloses the following aspects.
[0208] The outdoor lighting device (1) of the first embodiment includes a pole (2), a luminaire (3), a surveillance camera (6), and a deterioration detection device (4). The pole (2) has a pole body (21) having an upper end and a lower end. The pole (2) is installed outdoors. The luminaire (3) is held by the pole (2) at the upper end side of the pole body (21). The surveillance camera (6) is held by the pole (2) at the upper end side of the pole body (21). The deterioration detection device (4) detects deterioration of the lower end of the pole body (21). The surveillance camera (6) transmits image data of the captured image to the management device (9). The deterioration detection device (4) performs a deterioration detection operation to detect the presence or absence of deterioration of the lower end of the pole body (21) in response to an instruction from the management device (9). The deterioration detection device (4) transmits information indicating the result of the deterioration detection operation to the management device (9).
[0209] According to this embodiment, the outdoor lighting device (1) can be efficiently managed, and the burden on the inspector inspecting the outdoor lighting device (1) can be reduced. Also, the inspector can determine whether or not to inspect the outdoor lighting device (1) without visiting the installation site of the outdoor lighting device (1).
[0210] The outdoor lighting device (1) of the second embodiment is the same as the outdoor lighting device (1) of the first embodiment, and further includes a monitoring mark (7). The monitoring mark (7) is disposed within the imaging range (R2) of the monitoring camera (6). The monitoring mark (7) is a mark for monitoring whether or not the pole body (21) is inclined relative to the vertical direction.
[0211] According to this embodiment, it is possible to detect the occurrence of an inclined state of the support (2).
[0212] The outdoor lighting device (1) of the third aspect is the same as the outdoor lighting device (1) of the second aspect, and further includes a cover (5) that covers the deterioration detection device (4). A monitoring mark (7) is provided on the outer surface of the cover (5).
[0213] According to this embodiment, the monitoring mark (7) is less likely to be a hindrance compared to when the monitoring mark (7) is provided somewhere other than on the cover (5).
[0214] In the outdoor lighting device (1) of the fourth embodiment, in the third embodiment, the cover (5) is attached to the pole body (21) at the lower end thereof and has a hollow frustum shape so as to surround the entire circumference of the pole body (21).
[0215] According to this embodiment, the lower end of the pillar body (21) can be protected by the cover (5).
