[0010] Below, a communication pole, a street light, and a communication module according to embodiments of the present invention will be described in detail with reference to the drawings. Note that each of the embodiments described below represents a specific example of the present invention. Therefore, the numerical values, shapes, materials, components, component arrangements and connection forms, steps, and step sequences shown in the following embodiments are merely examples and are not intended to limit the present invention. Therefore, among the components in the following embodiments, components not recited in the independent claims will be described as optional components.

[0011] Furthermore, each figure is a schematic diagram and is not necessarily an exact illustration. Therefore, for example, the scales of the figures do not necessarily match. Furthermore, in each figure, substantially the same components are given the same reference numerals, and redundant explanations are omitted or simplified.

[0012] Furthermore, in this specification, terms indicating the shape of elements such as cylinders and prisms, as well as numerical ranges, are not expressions that express only the strict meaning, but also expressions that include a substantially equivalent range, for example, a difference of about a few percent.

[0013] Furthermore, in this specification, ordinal numbers such as "first" and "second" do not refer to the number or order of components unless otherwise specified, but are used for the purpose of avoiding confusion and distinguishing between components of the same type.

[0014] (Embodiment) [overview] First, an overview of a street light according to an embodiment will be described with reference to FIG.

[0015] Fig. 1 is a schematic side view of a street light 1 according to this embodiment. The street light 1 shown in Fig. 1 is a lighting device that is installed on the ground, such as on a road, a walkway, a parking lot, a plaza, or a park, or on a structure such as a bridge, an elevated road, or a building, and illuminates the area below (the ground). As shown in Fig. 1, the street light 1 includes a communication pole 2 and a lighting fixture 20. The communication pole 2 includes a pole 10, communication modules 100 and 101, and a cover 30.

[0016] The pole 10 is erected on the ground so as to extend vertically upward. The height of the pole 10 is, for example, several meters to several tens of meters. The pole 10 is, for example, a cylindrical body (e.g., a cylinder) with at least a portion of its interior hollow, but is not limited to this. The pole 10 may also be a prismatic body (e.g., a rectangular cylinder) with at least a portion of its interior hollow. Alternatively, the pole 10 may have a shape that tapers from the bottom to the top. Furthermore, the pole 10 may be provided so as to extend obliquely upward relative to the ground or the ground surface. The pole 10 is made of metal, but may also be made of resin.

[0017] The lighting fixture 20 is attached to the tip (top end) of the pole 10. The lighting fixture 20 is a lighting fixture including a light emitting element such as an LED (Light Emitting Diode). The shape and size of the lighting fixture 20 are not particularly limited.

[0018] The communication modules 100 and 101 are box-shaped modules that include a communication device. The specific configurations of the communication modules 100 and 101 will be described later.

[0019] The lid 30 is a lid that covers the top surface of the communication module 101. Although details will be described later, an opening is provided on the top surface of the communication module 101, and the lid 30 closes this upper opening.

[0020] [Communication module placement] Next, the arrangement of the communication modules attached to the communication pole 2 will be described with reference to Fig. 2 to Fig. 4. Fig. 2 to Fig. 4 are diagrams showing examples in which one, two, and three communication modules are attached to the pole 10 in the street light 1 according to this embodiment, respectively.

[0021] When the maintenance of the communication devices contained therein is taken into consideration, it is preferable to mount each communication module near the ground (or the ground surface), but the location is not limited thereto.

[0022] One or more communication modules can be attached to the street light 1 and communication pole 2 according to this embodiment. Fig. 2 shows an example in which only one communication module 100 is attached. Figs. 1 and 3 show an example in which two communication modules 100 and 101 are attached. Fig. 4 shows an example in which three communication modules 100, 101, and 102 are attached.

[0023] The communication module 100 shown in Figures 2 to 4 is an example of a first communication module. The communication module 101 shown in Figures 3 and 4 and the communication module 102 shown in Figure 4 are each an example of a second communication module. The second communication module is an additional module that is provided in addition to the first communication module. The second communication module can be added or removed depending on the communication performance required for the communication pole 2.

[0024] The communication pole 2 shown in Figures 1 and 3 is obtained by adding a communication module 101 to the communication pole 2a shown in Figure 2. Specifically, the lid 30 shown in Figure 2 is removed, the communication module 101 is fixed on top of the communication module 100, and then the lid 30 is attached to the communication module 101. The same applies when adding a communication module 102. Adding a communication module 102 to the communication pole 2 shown in Figure 3 results in the communication pole 2b shown in Figure 4.

[0025] The communication modules 100, 101, and 102 have the same configuration. Specifically, each of the communication modules 100, 101, and 102 includes a housing 120, a housing fixture 130, and an equipment fixture 140. In this embodiment, the housing 120, the housing fixture 130, and the equipment fixture 140 are the same in each of the communication modules 100, 101, and 102.

[0026] Each of the communication modules 100, 101, and 102 includes one or more communication devices. Specifically, as shown in Fig. 2 to Fig. 4, the communication module 100 includes a radio device 111 and a power supply panel 112. The communication module 101 includes a radio device 111a and a frequency sharer 113. The communication module 102 includes a radio device 111b.

[0027] The wireless device 111 is an example of a first communication device. The wireless devices 111a and 111b are each an example of a second communication device. The wireless devices 111, 111a, and 111b each transmit and receive wireless signals based on a predetermined communication standard via an antenna (not shown). The wireless device 111a processes wireless signals at a different frequency than the wireless device 111. The wireless device 111b processes wireless signals at a different frequency than both the wireless devices 111 and 111a, but the frequency may be the same. The antenna is attached, for example, at the top of the pole 10, between the lighting fixture 20 and the communication module 100.

[0028] The power supply panel 112 is a device that supplies power to the radio device 111, the antenna, etc. In the example shown in Fig. 3, the power supply panel 112 also supplies power to the radio device 111a and the frequency sharer 113. In the example shown in Fig. 4, the power supply panel 112 also supplies power to the radio device 111b. For example, the power supply panel 112 includes a transformer, a current transformer, a circuit breaker, etc.

[0029] The frequency sharer 113 is a device that shares or demultiplexes radio signals between the multiple radio devices 111 and 111a and an antenna (not shown). In the example shown in Fig. 4, the frequency sharer 113 shares or demultiplexes radio signals between the multiple radio devices 111, 111a, and 111b and an antenna.

[0030] The only device included in the communication module 102 is the radio 111b, so there is space to accommodate other devices. Devices such as radios can be added to the communication module 102 as needed.

[0031] Furthermore, the types, numbers and combinations of devices included in the communication modules 100, 101 and 102 are not limited to the examples shown in Figures 2 to 4. For example, a power supply panel 112 may be provided for each communication module.

[0032] Furthermore, the number of communication modules attached to the communication pole 2 is not limited to one to three, but may be four or more. Although an example in which a plurality of communication modules are stacked one above the other has been shown, the arrangement of the communication modules is not limited to this. Examples of different arrangements of the communication modules will be described later.

[0033] [Communication module configuration] Next, the specific configurations of the communication modules 100, 101, and 102 will be described. As described above, the communication modules 100, 101, and 102 differ in the types and number of devices housed therein, but are otherwise identical in configuration. Below, the communication module 100 will be described as a representative, using Figures 5 and 6.

[0034] Fig. 5 is a perspective view of communication modules 100 and 101 according to this embodiment. Fig. 6 is a top view of communication module 100 according to this embodiment.

[0035] 5 shows the internal structure of the communication module 100 with the front cover 121 of the housing 120 removed. The radio 111 and power supply panel 112 included in the communication module 100 are not shown.

[0036] 2 to 4, the communication module 100 includes a housing 120, a housing fixture 130, and a device fixture 140. In addition, as shown in FIG. 6, the communication module 100 includes a locking mechanism 150.

[0037] The housing 120 is an openable / closable housing. The housing 120 is a box-shaped container that houses a communication device such as the radio 111. The housing 120 covers the periphery of the communication device. Note that the housing 120 does not have to cover the entire periphery of the communication device. For example, the housing 120 according to this embodiment does not cover the top and bottom of the communication device.

[0038] 5 and 6, the housing 120 includes a front cover 121 and a rear cover 122. The housing 120 is configured to have a cylindrical shape by combining the front cover 121 and the rear cover 122.

[0039] The housing 120 is provided with a locking mechanism 150 that restricts opening and closing. The locking mechanism 150 is, for example, an electronic lock, but is not limited to this. The locking mechanism 150 may be configured so that it cannot be opened or closed without a special tool.

[0040] The housing 120 has openings on both its top and bottom surfaces. The top and bottom surfaces of the housing 120 are parallel to each other and have the same size and shape. The openings on the top surface of the housing 120 and the openings on the bottom surface of the housing 120 have the same size and shape. This allows multiple housings 120 to be stacked one on top of the other without any gaps.

[0041] The opening at the top of the housing 120 of the communication module 101 is closed by placing the lid 30 thereon, as shown in Fig. 5. The lid 30 is engaged with the housing 120, but may also be fixed to the housing 120 by screws or the like.

[0042] In this embodiment, rear cover 122 of housing 120 is fixed to housing fixture 130. For example, rear cover 122 is screwed to housing fixture 130. Front cover 121 is fixed by being fitted into rear cover 122. Note that the method for fixing front cover 121 and rear cover 122 is not particularly limited. Both front cover 121 and rear cover 122 are made of metal, but may also be made of resin.

[0043] 5, a large number of air holes 121a are provided in the housing 120. The air holes 121a can prevent heat from building up inside the housing 120. Note that the air holes 121a do not necessarily have to be provided. The air holes 121a are provided on the side surfaces of the housing 120, but the location is not particularly limited.

[0044] The shape (cross-sectional shape) of the housing 120 in a cross section perpendicular to the axial direction (vertical direction) of the pole 10 is substantially the same regardless of the position of the cross section. In other words, the shape of the housing 120 as viewed from above is the same as the shape of the housing 120 as viewed from below, and is also substantially the same as the cross-sectional shape at any position.

[0045] In this embodiment, as shown in Fig. 6, the cross-sectional shape of the housing 120 is a combination of a semicircular shape located on the rear side (upper side of the paper) and a rectangular shape that is wider than the semicircular shape located on the front side (lower side of the paper). The semicircular part is formed by a part of the rear cover 122, and forms a space 123 for inserting the pole 10. The semicircular part is provided only in a part of the rear cover 122 in the vertical direction (for example, see Fig. 7 described later). The wider rectangular part is formed by the front cover 121 and a part of the rear cover 122.

[0046] The outer surface of the housing 120 has curved corners in a cross section perpendicular to the axial direction of the pole 10. Specifically, in the cross section shown in FIG. 6, curved lines are formed at the four corners of the rectangular shape on the front side. The curved lines are, for example, circular arcs. For example, if the outer shape of the housing 120 in a top view is considered to be a rectangle, the length of the long side is A [mm] and the length of the short side is B [mm]. In this case, the curvature k of the curved line satisfies, but is not limited to, 1 > k ≥ 1 / b. The shape of the housing 120 in a top view is not limited to a rectangle and may be a polygon within a predetermined dimension.

[0047] In this way, the corners of the housing 120 are curved, so that the wind blowing onto the housing 120 can be smoothly deflected. The force exerted on the housing 120 by the wind can be alleviated, and the falling off of the communication module 100 or the damage to the pole 10 can be suppressed. The fewer straight line portions the housing 120 has and the closer it becomes to a circle, the more the force exerted on the housing 120 by the wind can be alleviated.

[0048] The cross-sectional shape of housing 120 is not limited to the example shown in Fig. 6. For example, curved corners may be provided only on front cover 121. Alternatively, the rectangular portion may be circular or elliptical. Reducing the flat surface portion of housing 120 makes it easier to deflect wind.

[0049] 6, the housing fixture 130 includes two strip-shaped members 131 and 132. The pole 10 is sandwiched between the strip-shaped members 131 and 132 and fastened with screws, thereby fixing the housing fixture 130 to the pole 10. The rear cover 122 of the housing 120 and the device fixture 140 are fixed to the housing fixture 130. The rear cover 122 and the device fixture 140 are fastened to the housing fixture 130 with screws, for example. One screw may be used both to fasten the housing fixture 130 and to fix the rear cover 122 and the device fixture 140.

[0050] 5, the communication module 100 includes two housing fixtures 130, but is not limited to this. The two housing fixtures 130 are housed inside the housing 120 and are arranged at different positions in the vertical direction. The housing fixtures 130 are metal fittings, but may also be made of resin. Note that the specific configuration of the housing fixtures 130 is not particularly limited as long as they can fix the housing 120 to the pole 10.

[0051] Device fixture 140 has a groove extending in the vertical direction. Device fixture 140 is a member with a rectangular ring-shaped cross section. As shown in Fig. 6, a device such as radio 111 can be fixed by clamping a part of device fixture 140 with the head of a screw. Because device fixture 140 extends in the vertical direction, it is possible to fix the device at any position in the vertical direction.

[0052] 5 and 6, the communication module 100 includes two device fixtures 140, but is not limited to this. The two device fixtures 140 are housed inside the housing 120 and are arranged on either side of the pole 10. The device fixtures 140 are metal fittings, but may also be made of resin. Note that the specific configuration of the device fixtures 140 is not particularly limited as long as they can fix one or more devices.

[0053] As shown in FIG. 6, the housing 120 has shafts 124 and 125 for wiring. The shafts 124 and 125 are each a space that passes through the housing 120 in the vertical direction. When multiple housings 120 are stacked one on top of the other, the shafts 124 of the housings 120 communicate with each other in the vertical direction, and the shafts 125 of the housings 120 communicate with each other in the vertical direction. For example, when two communication modules 100 and 101 are stacked as shown in FIG. 3, the upper end of the shaft 124 (first shaft) of the communication module 100 is connected to the lower end of the shaft 124 (second shaft) of the communication module 101. The upper end of the shaft 125 (first shaft) of the communication module 100 is connected to the lower end of the shaft 125 (second shaft) of the communication module 101. This facilitates wiring across multiple modules.

[0054] For example, multiple wirings (not shown) for supplying power and communication signals are connected to the radio devices 111 and 111a and the frequency sharer 113. The multiple wirings include low-voltage wirings and weak-current electric wires. The low-voltage wirings are arranged in multiple shafts 124 that communicate with each other. The weak-current electric wires are arranged in multiple shafts 125 that communicate with each other. This makes it possible to prevent the wirings from affecting each other by separating them from each other.

[0055] [Effects, etc.] As described above, the communication pole 2 according to this embodiment includes the pole 10 and the communication module 100. The communication module 100 includes a first communication device, a housing 120 that is an example of a first housing that houses the first communication device, and a housing fixture 130 that is an example of a first fixture that fixes the housing 120 to the pole 10.

[0056] This makes it easy to install the communication device because the communication device is housed in the housing 120 and modularized. Also, since the communication device is housed in the housing 120, it is not easily accessible from the outside, so the protection performance of the communication device can be improved. This is particularly effective when multiple communication device modules are to be installed.

[0057] Also, for example, the communication pole 2 further includes one or more communication modules 101 and / or 102. Each of the one or more communication modules 101 and / or 102 includes a second communication device, a housing 120 that is an example of a second housing that houses the second communication device, and a housing fixture 130 that is an example of a second fixture that fixes the housing 120 to the pole 10. The second housing has the same size and shape as the first housing.

[0058] As a result, the shape and size of each housing 120 of the multiple communication modules 100 and 101 are the same, making expansion easy. Furthermore, when attaching the communication modules 100 and 101 to the top of the pole 10, the attachment strength and / or the shape of the housing 120 must be designed in advance, taking into account the effects of wind, so that the modules will not fall even if a strong wind blows. By making the shape and size of each housing 120 of the multiple communication modules 100 and 101 the same, the results of wind load resistance calculations for one communication module 100 can be effectively used.

[0059] Also, for example, the communication module 101 is disposed directly above the communication module 100 in contact therewith.

[0060] As a result, the communication modules 100 and 101 are stacked in the vertical direction, which reduces the road area (viewed from above). Also, by making the shape and size of each housing 120 of the multiple communication modules 100 and 101 the same, it is possible to easily calculate the wind load resistance of the stacked multiple communication modules 100 and 101.

[0061] Furthermore, for example, the housing 120 of each communication module has a wiring shaft 124. The shafts 124 of each housing 120 are in communication with each other.

[0062] As a result, the shaft 124 communicates between the communication modules 100 and 101, and therefore, a wiring path between the communication modules 100 and 101 can be easily secured.

[0063] Furthermore, for example, the shafts 124 and 125 are arranged on both sides of the pole 10.

[0064] This allows the shafts 124 and 125 to be spaced apart. For example, by using one of the shafts 124 and 125 as a wiring path for low-voltage wiring and the other of the shafts 124 and 125 as a wiring path for low-current electric wires, it is possible to prevent the low-voltage wiring from having an electromagnetic effect on the low-current electric wires.

[0065] Furthermore, for example, the outer surface of the housing 120 has curved corners in a cross section perpendicular to the axial direction of the pole 10.

[0066] This can reduce the wind pressure acting on the housing 120. Furthermore, by reducing the number of straight corners, the safety of workers when installing the communication module 100 can be improved.

[0067] Furthermore, for example, both end faces of the housing 120 in the axial direction of the pole 10 are flat surfaces that are parallel to each other and have the same size, and openings of the same size are provided on both end faces.

[0068] This allows the housings 120 to be stacked one on top of the other without any gaps, which can, for example, prevent foreign matter from entering the housings 120. Furthermore, by reducing the gaps between the housings 120, the effects of wind can also be reduced.

[0069] The street light 1 according to this embodiment includes a communication pole 2, 2a or 2b, and a lighting fixture 20 attached to the tip of the pole .

[0070] As a result, the communication device is housed in the housing 120 and modularized, making it easy to add more communication devices.

[0071] Moreover, the communication module 100 according to this embodiment includes a communication device, a housing 120 that houses the communication device, and a housing fixture 130 that fixes the housing 120 to the pole 10.

[0072] This makes it easy to add more communication devices because the communication devices are housed in the housing 120 and modularized. In addition, since the communication devices are housed in the housing 120, they cannot be easily accessed from the outside, which improves the protection performance of the communication devices.

[0073] Furthermore, for example, the housing 120 is an openable / closable housing, and has a locking mechanism 150 that restricts opening and closing.

[0074] This makes it possible to restrict access from the outside and improve the protection performance of the communication device. Note that the lock mechanism 150 does not necessarily have to be provided.

[0075] (others) The communication pole, street light, and communication module according to the present invention have been described above based on the above-mentioned embodiments, but the present invention is not limited to the above-mentioned embodiments.

[0076] For example, in the above embodiment, an example has been shown in which the communication pole 2 is used as a street light 1, but the present invention is not limited to this. The communication pole 2 may be a pole dedicated to communication. Alternatively, a functional module other than the lighting fixture 20 may be attached to the communication pole 2. For example, a surveillance camera may be attached to the communication pole 2. Furthermore, the surveillance camera may be provided inside the communication module 100, or may be provided separately from the communication module 100.

[0077] Furthermore, for example, the housings 120 of the communication modules 100, 101, and 102 may have different shapes or sizes. For example, the height of the housing 120 may differ for each module. If the size and shape of the top and bottom surfaces of each housing 120 are the same, they can be stacked without gaps even if they are of different heights.

[0078] Furthermore, the sizes and shapes of the top and bottom surfaces of each housing 120 do not have to be the same. For example, each housing 120 may have a shape that tapers in the vertical direction (tapered or stepped). In this case, multiple housings 120 can be stacked without gaps by alternately turning the housings 120 upside down.

[0079] Furthermore, one of the one or more second communication modules may be disposed on the opposite side of the pole 10 from the first communication module.

[0080] Fig. 7 is a side view of a communication pole according to a modified example of the embodiment. In the example shown in Fig. 7, four communication modules 201, 202, 203, and 204 are attached to a pole 10. The communication modules 201 and 203 are stacked one above the other, as in the embodiment. The communication modules 202 and 204 are also stacked one above the other.

[0081] The communication module 202 is disposed on the opposite side of the pole 10 from the communication module 201. The communication modules 201 and 202 according to this modification have a housing 220 instead of the housing 120. A rear cover 222 of the housing 220 is configured to cover only a portion of the side surface of the pole 10. The free space on the pole 10 can be used to attach another housing 220.

[0082] This allows for expansion not only above and below the existing communication module, but also on the opposite side, making it possible to effectively utilize the space around the aerial pole and increase the number of communication modules that can be installed.

[0083] In addition, the present invention also includes forms obtained by applying various modifications to each embodiment that a person skilled in the art would think of, and forms realized by arbitrarily combining the components and functions of each embodiment within the scope of the present invention.
