[0011] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Note that the following description and drawings have been omitted and simplified as appropriate for clarity of explanation. In addition, in each drawing, the same or similar elements are designated by the same reference numerals, and duplicate explanations are omitted as necessary.

[0012] 1A and 1B show a pole according to one embodiment of the present disclosure. FIG. 1A is a front view of the pole 100, and FIG. 1B is an exploded perspective view of the pole 100 viewed from an oblique direction. The pole 100 has a plurality of modules 110-1 to 110-4 connected to one another. In the following description, the modules 110-1 to 110-4 will also be referred to as modules 110 unless there is a particular need to distinguish them. The modules 110 may also be referred to as a pole unit or an assembly (ASSY).

[0013] The module 110 has a connection section that connects to other modules and a device housing section that is configured to be able to house devices. In one embodiment, the pole 100 is configured as a multi-function pole in which various devices are built into the modules 110-1 to 110-4. The modules 110-1 to 110-4 can house devices such as edge computers (MEC (Multi-access / Mobile Edge Computing) servers), security cameras, wireless communication devices, and 5G (5th Generation) base stations.

[0014] Among the multiple modules 110, the module 110-1 in the lowest layer may be connected to a module that serves as a base. The module of the base is not particularly limited, but may, for example, be at least partially buried in the ground. Alternatively, the module of the base may be connected to a foundation placed on the ground using fastening bolts or the like. The module of the base may be connected to a support buried in the ground.

[0015] The base module may be, for example, a module constituting a common section. The base module may have devices such as a power supply and a network device inside. The power supply supplies power to the devices mounted on each module 110. The base module may include a power meter for monitoring the amount of power used in each module. The network device is connected to an external network. The devices mounted on each module 110 may be configured to be able to communicate with the external network through the network device of the base module.

[0016] 1A and 1B show an example in which one pole has four modules 110, but the number of modules 110 connected to the pole 100 is not particularly limited. The pole 100 may have a plurality of modules 110 connected to each other.

[0017] 2 is a perspective view showing an example of the module 110. The module 110 has a cylindrical body 113. The body 113 is formed of a material such as metal. The body 113 can be formed of various materials depending on the strength required of the module and the weight that can be tolerated by the module. For example, a module 110 that is expected to be placed at a high location on the pole 100 may be formed of a lightweight material such as carbon fiber.

[0018] In this embodiment, a business that installs or owns the pole 100 can lend the equipment housing section (the right to use it) in the module 110 to another business. Hereinafter, the business that installs or owns the pole 100 will be referred to as a first user, and the business that rents the equipment housing section will be referred to as a second user. The first user can lend the equipment housing section to a second user, for example, on a module 110 basis. The second user can place equipment having a predetermined function in the equipment housing section.

[0019] In this embodiment, the wiring and the like within the module 110 are prepared by a first user, and the second user connects devices to the prepared wiring for use. In this case, if the second user were allowed to freely touch the wiring within the module 110 prepared by the first user, there is a possibility that the second user could accidentally damage the wiring connected to another module 110 that is connected to the module. Furthermore, if the first user were allowed to freely touch the devices within the module 110 installed by the second user, responsibility could become unclear if a malfunction occurs in the device.

[0020] In order to at least alleviate the above-mentioned problems, in this embodiment, the equipment housing section has a first area 121 and a second area 122. The first area 121 is an area accessible by a first user. The second area 122 is an area accessible by a second user. Here, being accessible means being able to physically contact items such as equipment arranged in the space of each area. By being able to access the first area or the second area, the user can arrange, maintain, or replace parts of equipment.

[0021] First area 121 is an area that can be accessed by a first user but not by a second user, for example. Second area is an area that can be accessed by a second user but not by a first user. In modules 110-1 to 110-4 shown in FIGS. 1A and 1B, if each module has a different second user, second area 122 of each module is accessible only to the second user to whom the equipment housing section of each module is rented.

[0022] For example, shared facilities are arranged in the first area 121. Devices having predetermined functions are arranged in the second area 122. The first area 121 may be connected between the coupled modules 110. In contrast, the second area 122 is an area independent of each module 110. The shared facilities are shared by the devices even when the devices arranged in the second area 122 are changed. For example, at least one of a communication line and a power line is arranged in the first area 121. The devices arranged in the second area 122 are connected to at least one of the communication line and the power line arranged in the first area 121. A distribution board for supplying power to the devices arranged in the second area 122 may be arranged in the first area 121.

[0023] Module 110 has a connecting portion at each end for connecting to other modules. In the example of Fig. 2, module 110 has a first connecting portion 111 located at the end in a first direction and a second connecting portion 112 located at the end in a second direction opposite to the first direction. First connecting portion 111 and second connecting portion 112 each include an interface for connecting to at least one of a communication line and a power line arranged in first region 121 of the connected module.

[0024] The second region 122 is separated from the first region 121 by, for example, a partition or a dividing wall. FIG. 3 shows an example of a partition used to separate the second region 122. The partitions include a first partition 133 and second partitions 131 and 132. The first partition 133 separates the first region 121 from the second region 122. The first partition 133 can function as a dividing wall that prevents physical access between the first region 121 and the second region 122. The second partitions 131 and 132 separate the second region 122 from the first connecting portion 111 and the second connecting portion 112, respectively. The second region 122 is configured as a space surrounded by the first partition 133 and the second partitions 131 and 132.

[0025] The first partition 133 may have an opening 134 that allows air to pass between the first area 121 and the second area 122. In this embodiment, the opening 134 is used as an air vent. The opening 134 may be breathable, and may be at least partially blocked with, for example, a mesh net. In the module 110, the position of the opening 134 may be determined at a predetermined position. The equipment arranged in the module 110 may have a blower fan for exhausting heat at the position of the opening 134. When the positions of the opening 134 and the blower fan are determined at predetermined positions, heat can be exhausted from the second area 122 to the first area 121 regardless of the equipment arranged in the second area 122.

[0026] The cross-sectional shape of the module 110 in a plane perpendicular to the longitudinal direction is not particularly limited, but may be elliptical or oblong. The length of each module (length in the longitudinal direction of the pole) may be different for each module, or may be the same. When the cross-sectional shape of each module in a plane perpendicular to the longitudinal direction is elliptical or oblong, devices can be housed more efficiently than when it is circular. In addition, the visual impression can be improved.

[0027] The module 110 may have a first cover member that covers the first area 121 and a second cover member that covers the second area 122. The first cover member protects the shared equipment arranged in the first area 121 from rain and wind. The second cover member protects the equipment arranged in the second area 122 from rain and wind. The first cover member and the second cover member may have an openable / closable mechanism, or may be detachably attached to the body 113.

[0028] FIG. 4 shows an example of a module 110 having a door. The module 110 has a first door 115 as a first cover member on the opening side of the first area 121. The module 110 also has a second door 116 as a second cover member on the opening side of the second area 122. The first door 115 and the second door 116 are each configured to be openable and closable with respect to the body 113. At least one of the first cover member and the second cover member may be a lid that is detachably attached to the body 113 using screws or the like. The first door 115 is provided with a key that can be unlocked by a first user. The second door 116 is provided with a key that can be unlocked by a second user. The keys may be mechanical keys or electronic keys.

[0029] A first user can unlock the key to the first door 115 and open the first door 115 to access the first area 121. The first user can unlock the keys to the first doors 115 in all of the multiple modules 110 that form the pole 100. A second user can unlock the key to the second door 116 and open the second door 116 to access the second area 122. The second user can only unlock the key to the second door 116 of the module 110 in which the second user has placed equipment, and cannot unlock the key to the second door 116 of the module 110 in which another user has placed equipment.

[0030] The first area 121 and the second area 122 are separated by a first partition 133. Therefore, the first user will not accidentally touch the equipment located in the second area 122 while working on the shared equipment located in the first area 121. Furthermore, the second user will not accidentally touch the shared equipment located in the first area 121 while working on the equipment located in the second area 122.

[0031] The second area 122 is closed by second partitions 131 and 132 (see FIG. 3) at the first connecting portion 111 and the second connecting portion 112 (see FIG. 2). In this embodiment, the second area 122 is formed as a closed space for each module 110, and therefore the independence of each module 110 is ensured for each second area 122. The second partitions 131 and 132 can protect the equipment arranged in the second area 122 of the upper and lower modules 110 from damage or tampering when an operator is working with the second door 116 open in a certain module 110.

[0032] 5 shows an example of shared facilities and equipment arranged in a first area 121 and a second area 122. In this example, a power line 145, a communication line 146, a distribution board 147, and a network switch 148 are arranged in the first area 121. Furthermore, equipment 152 having a predetermined function is arranged in the second area 122. Rails are formed in the second area 122, and the equipment 152 may be inserted into the second area 122 by sliding on the rails.

[0033] The module 110 has a power line interface 141 and a communication line interface 142 as interfaces with the module 110 on the lower layer side. The module 110 has a power line interface 143 and a communication line interface 144 as interfaces with the module 110 on the upper layer side.

[0034] In the module 110, the power line 145 is connected to power line interfaces 141 and 143. The power line interfaces 141 and 143 each have a terminal connected to the power line 145 in the module 110. The power line interface 143 of the lower module 110 is connected to the power line interface 141 of the upper module 110, thereby connecting the power line 145 of the lower module 110 to the power line 145 of the upper module 110. The power line interface 141 of the lowermost module 110 is connected to a power supply device provided in, for example, the module in the base section. The power line 145 may include power lines of multiple voltages. The power line 145 includes, for example, a DC power line and an AC power line. The power line 145 branches into a distribution board 147. The distribution board 147 includes a circuit breaker having, for example, a leakage current protection function.

[0035] In the module 110, the communication line 146 is connected to the communication line interfaces 142 and 144. The communication line interfaces 142 and 144 each have a terminal connected to the communication line 146 within the module 110. By connecting the communication line interface 144 of the lower module 110 to the communication line interface 142 of the upper module 110, the communication line 146 of the lower module 110 is connected to the communication line 146 of the upper module 110. The communication line interface 142 of the lowermost module 110 is connected to a communication device provided in, for example, a module in the base section. The communication line 146 is connected to a network switch 148. The network switch 148 is configured as a network device such as a Layer 2 switch.

[0036] A power connector 150 and a communication connector 151 may be arranged at the boundary between the first area 121 and the second area 122, for example, in the first partition 133 shown in FIG. 3 . The power connector 150 includes a terminal connected to a distribution board 147. The communication connector 151 includes a terminal connected to a network switch 148. The device 152 can receive power from the distribution board 147 through the power connector 150. The device 152 is also connected to the network switch 148 through the communication connector 151, and can communicate with an external device. The device 152 may be connected to the distribution board 147 and the network switch 148 through an opening 134 formed in the first partition 133. The positions of the power connector 150 and the communication connector 151 may be predetermined. The device 152 may also have connectors for connecting to the power connector 150 and the communication connector 151 at predetermined positions. In this case, the power connector 150 and the communication connector 151 can be connected to the connector of the device 152 without depending on the device 152 placed in the second area 122.

[0037] Openings may be formed in the first connecting portion 111 and the second connecting portion 112 (see FIG. 2) in portions corresponding to the first region 121, and the first region 121 may be configured to allow air to pass between the multiple modules 110. The pole 100 may have a mechanism for discharging heat to the outside in the upper module 110, the lower module 110, or the module in the base portion. In this case, heat from the device 152 arranged in the second region 122 is transferred to the first region 121 through the openings 134 (see FIG. 3) and can be discharged to the outside through the lower or upper module 110.

[0038] In the above embodiment, an example has been described in which the power line interfaces 141 and 143 and the communication line interfaces 142 and 144 are provided in the coupling section, and the modules 110 are coupled together, thereby connecting the power line 145 and the communication line 146 of each module. However, this embodiment is not limited to this. For example, the first user may individually arrange power lines and communication lines from a power supply device to each of the coupled modules 110 in the first area 121.

[0039] In this embodiment, the module 110 has a first area 121 and a second area 122. The first area 121 is used by a first user to place, for example, shared equipment, and the second area 122 is used by a second user to place, for example, equipment having a predetermined function. The first area 121 is accessible by the first user, and the second area 122 is accessible by the second user. In this embodiment, it is possible to limit the users who can access each area.

[0040] In this embodiment, a first user can access the first area 121 of each module 110, and a second user can access the second area 122 of the module 110 in which the second user places the device 152. The second user can place the device 152 having a predetermined function in the second area 122. After placing the device 152, the second user can perform work on the placed device 152. On the other hand, the first user can work on the shared equipment placed in the first area 121. However, the first user cannot freely access the second area 122 in which the second user has placed the device 152. In this embodiment, only the second user can touch the device 152, so there is no need to worry about the device 152 being tampered with by anyone other than the second user.

[0041] In comparison with Patent Document 1, the connecting pole described in Patent Document 1 has devices attached externally to the body of the connecting pole. In Patent Document 1, the devices are exposed to the outside, raising concerns about vandalism and damage. In contrast, in the present embodiment, the devices 152 are placed in the second area 122 accessible to the second user. This protects the devices 152 from vandalism and damage. Furthermore, in Patent Document 1, the more devices are attached, the more cluttered the exterior becomes. For example, if the pole is installed in a park or the like, the pole may not blend in with the scenery of the location where it is installed and may spoil the scenery. In contrast, in the present embodiment, the devices are housed inside the module 110. Therefore, the pole 100 according to the present embodiment has the advantage that the devices do not spoil the scenery.

[0042] In the above embodiment, an example has been described in which the pole 100 is formed by connecting multiple modules 110. However, the present disclosure is not limited to this. In the present disclosure, the pole 100 may include a module in which devices having predetermined functions are fixedly arranged. The module in which devices having predetermined functions are fixedly arranged includes areas corresponding to the first area 121 and the second area 122. For example, the pole 100 may include a module to which a traffic light is connected, a module to which a lighting fixture is connected, a module for charging an electric vehicle, and a module including a projector that projects light onto roads and surrounding structures. The pole 100 may include a module including a sensor for measuring wind speed, rainfall, or snowfall. The pole 100 may include a module including a LiDAR (light detection and ranging) and a module including a beacon receiver. The pole 100 may be installed in, for example, a park, a shopping center, or a store. The length of the pole 100 is not particularly limited, and the pole 100 may have a length of several meters to several tens of meters.

[0043] FIG. 6 shows a pole according to a first modification. In the first modification, the pole 100a is used for a traffic light. The pole 100a includes one or more modules 110 on which a second user can place a device having a predetermined function, and a module to which a traffic light 160 is connected. The pole 100a may also have a module to which a pedestrian signal light is connected. Furthermore, the pole 100a does not necessarily have a digital signage module.

[0044] FIG. 7 shows a pole according to a second modification. In the second modification, the pole 100b has a module to which a light 161 is connected in addition to the modules used in the pole 100a shown in FIG. 6. In this example, an edge computer included in any of the modules may analyze camera images and control the light 161 according to the analysis results. For example, when there is a person around the pole 100b, the edge computer may turn on the light 161 to brightly illuminate the intersection. The edge computer may change the brightness and color of the light 161 depending on whether there is a person present.

[0045] FIG. 8 shows a pole according to a third modification. In the third modification, the pole 100c is used as a lighting pole. The pole 100c includes one or more modules 110 in which a second user can place devices having predetermined functions, and a module to which two lights 161 are connected. In this example, an edge computer included in one of the modules may turn on the light 161 when a person is present around the pole 100c, thereby brightly illuminating the area where the pole 100c is installed. The edge computer may also change the brightness and color of the light 161 depending on whether a person is present or not.

[0046] Although the embodiments of the present disclosure have been described in detail above, the present disclosure is not limited to the above-described embodiments, and includes changes and modifications to the above-described embodiments without departing from the spirit and scope of the present disclosure.
