Description

Technical Field

[0001] The present invention relates to a control device for controlling electronic devices installed outdoors, such as communication devices compliant with various wireless communication standards including Wi-Fi (registered trademark), surveillance cameras, and environmental sensors, and a control device storage box for pole installation suitable for installation on power poles or communication poles, and an installation structure of the storage box and the electronic devices.

Background Art

[0002] Recently, the expansion of various services using public wireless communication networks has been progressing. For example, Internet connection services for personal mobile terminals and cashless terminals in stores using Wi-Fi (registered trademark) indoors and outdoors, crime prevention using surveillance cameras, and collection and distribution services of regional information by using cameras in event venues, shopping streets, tourist areas, etc., child monitoring services using ID tags, and collection services of environmental data such as temperature and humidity of multiple bases using environmental sensors cover a wide range of fields.

[0003] In the cable TV business, in existing apartment houses where cables are laid by the operator, aiming at further improvement of communication speed, a conversion from the conventional HFC (Hybrid Fiber Coaxial) system using both optical fiber cables and coaxial cables to the FTTH (Fiber To The Home) system constructed only with optical fiber cables is being planned.

[0004] Electronic devices such as communication devices, cameras, and environmental sensors for implementing the above services are usually installed on the wall surface of a building or installed on poles separately erected on the road, and the control devices for controlling these electronic devices are often installed inside the building. However, in order to secure space inside the building for installing the control devices, it is necessary to obtain permission for use from the owner of each building one by one, and the installation preparation is cumbersome. Therefore, if it is possible to install the control devices including electronic devices outdoors by using power poles and communication poles owned by power companies and communication companies, the destination for obtaining permission for use of the installation location is narrowed down, and the installation preparation becomes simple.

[0005] In addition, in the cable television business, when converting from the HFC method to the FTTH method, if the wiring space is full with the existing cables, an event may occur where facility renovation for the conversion cannot be performed. Also, although it is conceivable to newly lay FTTH cables separately from the existing cables to avoid facility renovation, in that case, it becomes difficult to maintain and manage the facilities of both the old and new methods, so such a means is not preferable either.

[0006] Therefore, it is conceivable to install communication devices compliant with Wi-Fi (registered trademark) outdoors of existing apartment houses and wirelessly connect to devices inside the house from outside the building. In that case, as the installation location of the communication devices, similar to the case of the above services, if it is possible to use power poles and communication poles erected around the building, the conversion of the above method becomes possible.

[0007] In each of the above services, when using power poles and communication poles, a storage box for outdoor installation suitable for them is used. However, since it is inevitably exposed to direct sunlight on the pole, a heat shield is provided on the outside and a storage box provided with a fan for stirring the air inside the box is proposed so that the temperature rise inside the storage box due to direct sunlight does not have an adverse effect on the control device (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0009] However, the storage box described in Patent Document 1 mainly aims to release the heat inside the storage box to the outside through the heat dissipation fins provided on the heat insulation plate. The fan provided inside the storage box is merely for stirring the internal air by its rotation to keep the temperature inside the sealed storage box substantially constant. That is, since the fan inside the storage box is not for forcibly lowering the temperature inside the box, especially when the heat dissipation by the heat dissipation fins of the heat insulation plate is insufficient in extremely hot weather, the air inside the storage box becomes uniformly high temperature, so there is a disadvantage that it is not suitable for storing control devices that are vulnerable to high temperatures.

[0010] Also, conventionally, an electronic device and a control device for controlling the same are usually stored in one storage box. For this reason, a storage box with a large capacity is required, and since the space inside the storage box is limited, there is a disadvantage that it is difficult to perform maintenance work on the electronic device and the control device.

[0011] The present invention has been made in view of such points, and its object is to block direct sunlight and prevent the temperature inside the storage box from rising, while introducing outside air into the storage box and discharging the air inside the storage box to the outside, so as to protect the control device inside the storage box from damage caused by high temperature even in extremely hot weather.

Further, a heat insulating plate is attached to the outer surface side of the top plate, the back plate, and / or the cover plate with a gap therebetween, and air conditioning means for ventilating the storage space is provided on one or both of both side plates.

[0014] In the above control equipment storage box for pole installation, the air conditioning means includes a plurality of ventilation fans responsible for exhausting hot air in the storage space and an air supply port responsible for introducing outside air into the storage space, and these ventilation fans are controlled so as not to stop operating simultaneously by a temperature controller provided in the storage space.

[0015] Also, in the above control equipment storage box for pole installation, a power outlet may be provided in the storage box body, and power may be supplied to the control device through the power outlet.

[0016] Furthermore, in the above control equipment storage box for pole installation, the storage box body may be painted in a color with excellent heat insulation effect.

Mode for Carrying Out the Invention

[0021] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0022] This embodiment is shown in FIGS. 1 to 7. This control device storage box 1 for pole installation is for installing a control device for controlling an electronic device 7 installed outdoors on a power pole P or a communication pole, as shown in FIGS. 5 and 6. In the figure, a communication device compliant with Wi-Fi (registered trademark) is shown as the electronic device 7, but the electronic device 7 is not limited to this and may be a surveillance camera, an environmental sensor, or the like.

[0023] The storage box 1 includes a storage box body 10 having a storage space for a control device that controls the electronic device 7. As shown in FIGS. 1 and 2, this storage box body 10 includes a rectangular back plate 11, a pair of side plates 12 and 13 extending from both side edges of the back plate 11 to the front side of the back plate 11, a top plate 14 provided between the upper end edges of these side plates 12 and 13 and the back plate 11, and a bottom plate 15 provided between the lower end edges of both side plates 12 and 13 and the back plate 11 and having a plurality of wire inlet openings 151, and a cover plate 16 that closably closes an opening defined by the front end edges of both side plates 12 and 13, the top plate 14, and the bottom plate 15.

[0024] On the back panel 11, in its lower region, as shown in Fig. 2, there are arranged an outlet 4 for supplying power to the control devices 2 and 3 (see Fig. 4) stored in the storage box main body 10, and a temperature regulator 5. Further, fixture mounting holes 111 and 112 are provided in two rows extending toward the side panels 12 and 13 from near the central part upward. Fixtures (not shown) such as bolts and nuts for attaching shelf members (not shown) on which the control devices 2 and 3 are placed are mounted in these fixture mounting holes 111 and 112. As a result, a plurality of shelf members can be arranged at arbitrary height positions, so that the control devices 2 and 3 can be installed vertically or horizontally on the shelf members. Further, the control devices 2 and 3 do not need to be attached and fixed to the storage box main body 10 and only need to be placed on the shelf members. Also, as will be described later, the power in the storage box 1 uses AC 100V and power is supplied from the outlet 4 to the control devices 2 and 3. Therefore, off-the-shelf commercial products of the outlet type can be adopted as the control devices 2 and 3, the options for the control devices 2 and 3 can be widened, and the maintenance work of the control devices 2 and 3 can be made extremely simple.

[0025] Of the pair of side plates 12 and 13, two ventilation fans 17, 17 are provided in one side plate 12, one above the other, over two upper and lower stages. Rain guards 171, 171 are provided outside these ventilation fans 17, 17 respectively. The ventilation fans 17, 17 are for exhausting the hot air in the storage box body 10 to the outside. These two ventilation fans 17, 17 are controlled so as not to stop operating simultaneously by the temperature regulator 5. Even if one ventilation fan 17 stops operating due to a failure, for example, the remaining ventilation fan 17 can always exhaust the hot air in the storage box body 10 to the outside, protecting the control devices 2, 3 from high temperatures. Incidentally, the number of ventilation fans 17 may be three or more as long as it is a plurality. Further, on the other side plate 13, air inlets 18, 18 are provided one above the other, over two upper and lower stages, near the lower part thereof. Rain guards 181, 181 are provided outside these air inlets 18, 18 respectively. When the ventilation fans 17, 17 start operating, outside air is taken into the storage box body 10 from the air inlets 18, 18, and the air in the storage box body 10, the temperature of which has risen due to the heat generation of the control devices 2, 3, is exhausted to the outside by the ventilation fans 17, 17. The above-mentioned ventilation fans 17, 17 and air inlets 18, 18 correspond to the air conditioning means in the present invention.

[0026] FIG. 4 shows an example of an electric circuit in the storage box main body 10. The power cable C drawn into the storage box main body 10 from the outside is connected to a three - port power outlet 4 via a breaker 6. Here, the power supplied via the power cable C is set to AC 100V, the same as that in a general household. As a result, since commercially available products of the power outlet type can be adopted as the control devices 2 and 3, no special tools are required for the installation and replacement work of the control devices 2 and 3, and no qualification of an electrician is required for those works, so the maintenance work can be extremely facilitated. The plug of the temperature regulator 5 is inserted into the power outlet 4, and power is supplied to each of the ventilation fans 17, 17 via the temperature regulator 5. Also, the plugs of a router - function - attached optical terminal device (D - ONU (Data Optical Network Unit)) 2 as a control device and a PoE switch 3 compatible with the PoE (Power over Ethernet) standard are inserted into the power outlet 4. Signals and power are supplied from the PoE switch 3 to a wireless communication device (electronic device) 7 installed outside the storage box main body 10.

[0027] One side edge of the cover plate 16 is made openable and closable at the front edge of one side plate 13 by hinges 161 provided at three positions of upper, middle and lower. Lock members 162, 162 for maintaining the closed state are provided on the free end side. On the other hand, wire inlet ports 151 are provided on the bottom plate 15 in two rows and four columns, and optical cables and power cables are introduced into the storage box main body 10 through these wire inlet ports 151.

[0028] In the storage box body 10 configured as described above, a heat insulation plate 19 as shown in Fig. 3 is attached to the outer surface sides of the top plate 14 and the lid plate 16 with a gap therebetween. This heat insulation plate 19 includes an upper surface plate 191 that covers the top plate 14, a front surface plate 192 that covers the lid plate 16, and attachment pieces 193 that extend parallel to the upper surface plate 191 from the lower ends of both side edges of the front surface plate 192. The heat insulation plate 19 is detachably attached to the storage box body 10 by upper fixing screws 194, 194 provided near the free ends at both side edges of the upper surface plate 191 and a lower fixing screw 195 provided at the tip of the attachment piece 193. In this embodiment, the heat insulation plate 19 covers only the two surfaces of the top plate 14 and the lid plate 16, but it may cover three surfaces including the back plate 11 as well.

[0029] Further, in the storage box 1, the storage box body 10 may be painted in a color with excellent heat insulation effect. Examples of the paint color include N8.5 (N white gray), 2.5Y9 / 1 (cream), 5Y7 / 1 (light beige), etc. described in the "Japanese Paint Industry Association Color Sample Book" published by the Japan Paint Industry Association. Note that it is not limited to these exemplary colors as long as the heat insulation effect is excellent. Also, the storage box 1 is preferably molded from a synthetic resin having insulating properties as a countermeasure against electric shock during the raising and lowering of the power pole due to electric leakage.

[0030] The storage box 1 and the wireless communication device 7 which is an electronic device described above are installed on the power pole P as shown in Figs. 5 to 7. Specifically, when the installation target is the power pole P as in this embodiment, as shown in Fig. 5, it is desirable that the storage box 1 be provided at a position below the communication line L and at a ground height of 4.5 m or more and 5.1 m or less, and separated from the side surface of the power pole P by 300 mm or more and 1000 mm or less.

[0031] In the installation, as shown in FIGS. 6 and 7, a holding member 80 composed of a plurality of band pieces 81 for holding the power pole P, a gun-shaped bracket 82 which is an installation arm with its base end fixed to the holding member 80, and a plurality of mounting brackets 83 are used to suspend the storage box 1 on one side surface of the gun-shaped bracket 82. Further, an electronic device 7 is attached to a mounting arm 84 extending from the tip of the gun-shaped bracket 82 to one side surface thereof. Since the storage box 1 and the electronic device 7 are configured to be attached separately in this way, when the electronic device fails, it is only necessary to replace only the electronic device 7 with a new one without opening the storage box 1. Also, when the control device side fails, the electronic device 7 does not interfere with the work inside the storage box 1, and the maintenance work is easy. Note that the attachment forms of the storage box 1 and the electronic device 7 are not limited to those shown in the illustrated example.

[0032] Note that the embodiments disclosed this time are illustrative in all respects and do not serve as a basis for a restrictive interpretation. Therefore, the technical scope of the present invention is not construed only by the above-described embodiments, but is defined based on the description in the claims for utility model registration. Also, the technical scope of the present invention includes all modifications within the meaning and scope equivalent to the claims for utility model registration.
