Description

[Technical Field]

[0001] The present invention relates to a portable storage box for wireless devices and a wireless network system. [Background technology]

[0002] At work sites such as forestry, cellular radio waves often do not reach the work site, so one option is to install Wi-Fi wireless devices at the work site and create a wireless network. Summary of the Invention [Problem to be solved by the invention]

[0003] However, in work sites such as forestry, tree felling and other tasks are performed over a relatively short period of time, and the work locations change frequently, so it is not efficient to perform tasks or construction work (for example, erecting poles or other structures for installing wireless devices) at each work site.

[0004] Furthermore, at work sites, the locations where tripods or the like can be used to easily set up wireless devices may be limited. For example, at forestry work sites, forest roads may be locations where footing is relatively flat compared to other locations, making them potential locations for easily setting up wireless devices using tripods or the like. However, setting up wireless devices on forest roads using tripods or the like may interfere with work vehicles traveling on the forest roads.

[0005] An exemplary object of the present invention is to enable wireless devices to be easily installed at work sites where wireless radio waves are out of range, in locations that do not interfere with on-site work. [Means for solving the problem]

[0006] A portable storage box for wireless devices according to one embodiment of the present invention comprises a resin case for storing wireless devices inside, and a non-metallic belt attached to the back of the case for fastening and securing the case to an object to which it is to be attached.

[0007] Furthermore, a wireless network system according to one aspect of the present invention includes a wireless access point formed by fixing the portable storage box to the attachment object. [Effects of the Invention]

[0008] According to one aspect of the present invention, at a work site where radio waves are out of range, wireless devices can be easily installed in a location that does not interfere with on-site work. [Brief explanation of the drawings]

However, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present invention, and are not intended to limit the subject matter described in the claims. Furthermore, more detailed descriptions than necessary may be omitted.

[0011] For example, detailed descriptions of well-known matters and redundant descriptions of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. Furthermore, identical or similar reference numerals indicate identical or similar elements, and repeated descriptions may be omitted. When numerical values ​​are described in the following description, the numerical values ​​are merely examples, and other numerical values ​​may be used in addition or instead.

[0012] <Summary> We will explain an example of how a wireless network can be easily constructed in a location where wireless communication such as cellular communication is out of range (for example, a work site such as a forestry work site), by storing wireless devices together in a portable storage box and attaching this portable storage box to a tree, for example.

[0013] <Embodiment> 1 to 3 are schematic front views of a portable storage box 10 for wireless devices according to one embodiment. Fig. 1 and Fig. 2 show a state in which a front cover 108 (see Fig. 3) of the portable storage box 10 is removed so that the interior can be seen from the front opening, and Fig. 3 shows a state in which the front cover 108 is attached to the portable storage box 10.

[0014] 1 shows a state in which no wireless devices are housed inside the portable storage box 10, while Fig. 2 shows a state in which wireless devices are housed inside the portable storage box 10. In the following, the portable storage box 10 may be abbreviated to simply "storage box 10."

[0015] 2, wireless devices that can be housed in the housing box 10 include, but are not limited to, an outdoor wireless device 301, a router 303, and a PoE (Power over Ethernet) injector 305. In this embodiment, it is assumed that the wireless devices housed in the housing box 10 are, for example, products that comply with the IEEE802.11 series, which is a Wi-Fi standard.

[0016] Figure 4 is a schematic rear view of the storage box 10 illustrated in Figures 1 to 3, and Figure 5 is a schematic side view showing the storage box 10 attached to a tree 500 (e.g., a trunk), which is an example of an object to be attached (or installed).

[0017] In each of Figures 1 to 5, the X axis corresponds to the direction that determines the width of the storage box 10, the Y axis corresponds to the direction that determines the height of the storage box 10, and the Z axis corresponds to the direction that determines the thickness (or depth) of the storage box 10 when viewed from the side (see, for example, Figure 5).

[0018] The size (width, height, and thickness) of the storage box 10 is not particularly limited as long as it is large enough to accommodate wireless devices therein. In other words, the size of the storage box 10 may be changed as appropriate depending on the size of the wireless devices to be accommodated therein. As a non-limiting example, the width, height, and thickness of the storage box 10 may each be approximately several tens of centimeters (cm).

[0019] As shown in Fig. 1, the housing box 10 has a rectangular parallelepiped case 102 with an open front. However, the shape of the case 102 may include curved portions. For example, a non-metallic material that is easily transparent to radio waves and lightweight is suitable as the material for the case 102. As a non-limiting example, a resin material such as plastic may be used for the case 102.

[0020] The attachment structure of front cover 108 (see FIG. 3) to case 102 is not particularly limited, but for example, front cover 108 may be attached to case 102 as a door that can be opened and closed by a hinge provided on two case side surfaces facing each other in the X-axis direction. Also, for example, a structure may be used in which slide grooves are provided on the inner walls of case side surfaces facing each other in the X-axis direction or the Y-axis direction, and front cover 108 slides along the slide groove to open and close the case opening. Front cover 108 of case 102 and case 102 may be provided with a structure that locks the case opening when it is closed by front cover 108.

[0021] Of the two side surfaces (top and bottom surfaces) of case 102 facing each other in the X-axis direction, one (for example, the top surface) is provided with roof portion 106, and on the other surface (for example, the bottom surface), as shown schematically in FIG. 6, for example, a U-shaped protruding handle (or grip portion) 104 for making storage box 10 portable is attached to a mounting bracket 114 provided on the back surface of case 102, as will be described later with reference to FIG. 4. Storage box 10 is attached with its back surface facing the object to which it is attached, and with roof portion 106 facing upward. The shape of handle 104 is not particularly limited, and may be any shape that is easy to grip with a human hand.

[0022] Two cable connection ports 126a and 126b, each having a through-hole leading to the inside of the case 102, are provided on the side of the case 102 on which the handle 104 is provided, for example. For example, as shown in FIG. 2, a communication (e.g., local area network (LAN)) cable 501 can be passed through the inside of the case 102 via one cable connection port 126a, and a power cable 503 of a power tap 307 can be passed through the inside of the case 102 via the other cable connection port 126b.

[0023] 3 to 7, cable connection ports 126a and 126b are not shown. The number of cable connection ports is not limited to two, but may be one, or three or more. Multiple cables may be inserted into one cable connection port.

[0024] As described below with reference to FIG. 8, the LAN cable 501 may be connected, for example, to an Internet connection device 802 that provides a communication connection to the Internet, and the power cable 503 may be connected, for example, to an external power source (e.g., a portable power source) 806.

[0025] As illustrated in FIG. 2, by providing cable connection ports 126a and 126b on the side of case 102 where handle 104 is provided, it is easy to carry storage box 10 by holding handle 104, even when, for example, LAN cable 501 and / or power cable 503 are attached.

[0026] For example, if cable connection ports 126a and 126b were provided on the side of case 102 opposite to the side on which handle 104 is provided, cables such as LAN cable 501 and / or power cable 503 would likely interfere with the ground, making it difficult to carry storage box 10. Also, the cables would be more likely to be damaged by interference with the ground. Therefore, by providing cable connection ports 126a and 126b on the side of case 102 on which handle 104 is provided, it is possible to, for example, carry storage box 10 smoothly and protect the cables.

[0027] 1, a base plate 122 made of, for example, wood (or resin such as plastic) is provided on the bottom surface in the depth direction of storage box 10, and a plurality (for example, six sets) of fixing band attachment portions (for example, metal fittings) 131a-131b, 132a-132b, 133a-133b, 134a-134b, 135a-135b, and 136a-136b are fixed, for example, with screws, onto base plate 122. Note that the method for attaching base plate 122 to storage box 10 is not particularly limited, but may be, for example, fixed with screws.

[0028] 1, a fixing band can be attached to each of the fixing band attachment parts to fasten and fix wireless devices to the substrate 122. For example, a hook-and-loop fastener with adjustable length, such as Velcro (registered trademark), can be used for the fixing band.

[0029] 2, fixing bands 141a and 141b are attached to the pair of fixing band attachment portions 131a-131b and the pair of fixing band attachment portions 132a-132b, respectively, for fastening and fixing wireless device 301 in, for example, a cross shape on substrate 122. Note that in FIG. 2, the reference numerals of the fixing band attachment portions shown in FIG. 1 have been omitted for clarity.

[0030] Furthermore, fixing bands 142a and 142b are attached to the pair of fixing band attachment portions 133a-133b and the pair of fixing band attachment portions 134a-134b, respectively, for fastening and fixing the router 303 on the substrate 122, for example, in a cross shape.

[0031] Furthermore, fixing bands 143a and 143b for fastening and fixing PoE injector 305 on board 122 are attached to the pair of fixing band attachment portions 135a-135b and the pair of fixing band attachment portions 136a-136b, respectively.

[0032] In this way, by using fixing bands to fix wireless devices such as the wireless device 301, the router 303, and / or the PoE injector 305 inside the case 102, the wireless devices can be easily attached and detached inside the case 102.

[0033] Therefore, for example, compared to fixing wireless devices to the inner wall of the case 102 of the storage box 10 by screws without using the board 122, it is possible to reduce the workload and time required for replacement work due to malfunction of wireless devices, upgrades, introduction of new products, etc., and improve work efficiency. Also, because the number of screw fixing points to the inner wall of the case 102 can be reduced, it is possible to prevent damage to resin materials such as plastic at screw fixing points in field environments such as cold regions where the temperature drops below freezing.

[0034] The fixing band may be a flexible (or pliable) non-metallic band made of resin, cloth, leather, rubber, etc. The number and arrangement of fastening points by the fixing band illustrated in Fig. 2 are merely examples, and a different number and / or arrangement from those in Fig. 2 may be applied.

[0035] For example, as described above, by using a non-metallic material such as wood or resin for board 122, the screw fastening positions on board 122 for the fixing band attachment portions can be easily changed, which makes it possible to flexibly change the number and / or arrangement of fastening points on board 122 where the fixing bands are fastened. Therefore, for example, it is possible to flexibly accommodate size changes accompanying replacement of wireless devices housed in case 102.

[0036] In FIG. 2, when attention is focused on the electrical connection relationship of the wireless devices, the wireless device 301 is connected to a first port of the PoE injector 305, which serves both as data input / output and power supply, by a LAN cable 351, for example.

[0037] PoE injector 305 is connected to power tap 307 by, for example, a power cable, and receives power from an external power supply (not shown) connected to power tap 307 by power cable 503. A second port of PoE injector 305 related to data input / output is connected to one of the LAN ports of router 303 by, for example, LAN cable 331.

[0038] The router 303 is connected to a power strip 307 that provides a connection to an external power source, for example, by a power adapter 333 that is provided with the router 303. In the router 303, a LAN cable 501 that provides a communication connection to a wide area network (WAN) such as the Internet can be connected to a WAN port, and this LAN cable 501 can be connected to, for example, an Internet connection device 802 (described later with reference to FIG. 8).

[0039] Due to the connection relationship illustrated in FIG. 2, for example, power is supplied from an external power source 806 (see FIG. 8) to the wireless device 301 via the power cable 503, the power tap 307, and the PoE injector 305, and power is supplied to the router 303 via the power tap 307 and the power adapter 333.

[0040] Furthermore, in terms of data communication, data received wirelessly by the wireless device 301 is input to the PoE injector 305 via the LAN cable 351, and is then input from the PoE injector 305 to the router 303 via the LAN cable 331. The router 303 transmits the received data to another communication device (for example, the wireless device 301 of another storage box 10 or the internet connection device 802 described later in FIG. 8) via, for example, the wireless device 301 or the LAN cable 501.

[0041] Transmission data input from the Internet connection device 802 to the router 303 via the LAN cable 501 is input to the PoE injector 305 via the LAN cable 331, input from the PoE injector 305 to the wireless device 301 via the LAN cable 351, and transmitted wirelessly from the wireless device 301.

[0042] Although it depends on the environmental temperature in which the storage box 10 may be installed, in this embodiment, the wireless devices 301, 303, 305, LAN cables 331, 351, 501, power tap 307, power adapter 333, and power cable 503 may each have the performance to withstand cold environments below freezing, for example, -20°C.

[0043] Next, referring to the front view of Fig. 3, fluorescent tape (or fluorescent sticker) 182 may be attached to one or more positions on the front cover 108 of the storage box 10. Fig. 3 shows an example in which fluorescent tape 182 extending in the Y-axis direction is attached near both ends of the front cover 108 in the X-axis direction. The color of the fluorescent tape 182 is not particularly limited, but may be orange, yellow, green, etc.

[0044] Although the application of fluorescent tape 182 is not essential, application of fluorescent tape 182 can, for example, increase the visibility of storage box 10 in the environment in which storage box 10 is installed. Therefore, for example, it is possible to improve the efficiency of tasks such as identifying and checking the installation location of installed storage box 10 and retrieving storage box 10.

[0045] Instead of attaching fluorescent tape 182, fluorescent paint may be applied to front cover 108. Additionally or alternatively, fluorescent tape 182 or fluorescent paint may be attached to one or both of the side surfaces of case 102 that face each other in the X-axis direction, or may be applied to one or both of the top and bottom surfaces of case 102 that face each other in the Y-axis direction.

[0046] Next, an exemplary rear structure of the storage box 10 will be described with reference to Fig. 4. As shown in Fig. 4(a), mounting brackets 112 and 114 extending in the X-axis direction are provided on the upper and lower parts of the rear surface of the storage box 10 in the Y-axis direction.

[0047] The upper mounting bracket 112 is provided with a guide bracket 200 having a plurality of (e.g., two) holes 201 through which the belt 120 can be inserted for fastening and securing the storage box 10 to a pillar-like object (e.g., a tree 500 as shown in FIG. 5). The guide bracket 200 has a protruding portion that is U-shaped (or trapezoidal) in side view, as shown in the partially enlarged perspective view of FIG. 4(b), for example. When the guide bracket 200 is attached to the mounting bracket 112 with a bolt 205, for example, a gap 202 corresponding to the U-shape is formed between the guide bracket 200 and the mounting bracket 112. This gap 202 can be used as the gap 202 through which the belt 120 passes when the belt 120 is converted into a shoulder belt for carrying the storage box 10 on the back, as will be described later with reference to FIG. 7(b).

[0048] The belt 120 may be a flexible (or pliable) non-metallic belt made of, for example, resin, cloth, leather, or rubber, similar to the fixing band described above. As a non-limiting example, the belt 120 may be made of a polyamide synthetic resin, also known as "nylon." Polyamide synthetic resin is suitable for the belt 120 because it is inexpensive and durable.

[0049] By using the resin belt 120, the risk of damaging an object (e.g., a tree 500) to which the storage box 10 is attached can be reduced. The resin belt 120 may be, for example, a ratchet belt. By using the resin ratchet belt 120, the risk of damaging an object such as the tree 500 to which the storage box 10 is attached can be reduced, and the storage box 10 can be easily fastened and fixed to the tree 500. Note that in this embodiment, the resin belt 120 can be converted into a shoulder belt when carrying the storage box 10 on one's back, as will be described later with reference to FIG. 7.

[0050] The lower mounting bracket 114 is provided with a handle 104 that protrudes in the negative direction of the Y axis beyond the surface opposite the roof 106 in rear view, for example, and is also provided with a non-slip (or shock-absorbing) rubber 401 extending in the X axis direction. The handle 104 may be attached to the case 102 without the mounting bracket 114. However, attachment via the mounting bracket 114 makes it easier to ensure strength when carrying the case 102 by using the handle 104 and reduces the possibility of damage to the resin case 102. The rubber 401 is an example of an elastic member that can be used as a non-slip member. For example, as shown in FIG. 5, when the storage box 10 is fastened and fastened to a tree 500 at the position of the belt 120, the rubber 401 is provided in a position that comes into contact with the tree 500 below the fastening position in the Y axis direction.

[0051] The rubber 401 comes into contact with the tree 500, thereby preventing the storage box 10 from sliding downward. The rubber 401 can also prevent the storage box 10 from impacting the tree 500 and damaging the tree 500, for example.

[0052] By providing the rubber 401 on the lower back surface of the storage box 10, the number of points at which the storage box 10 is fastened to the tree 500 can be reduced to one, using the ratchet belt 120 provided on the upper back surface of the storage box 10. Furthermore, by having the rubber 401 in contact with the tree 500, the storage box 10 can be prevented from easily slipping downward, making it easier for a worker to install it alone. This reduces the burden and / or time required for installing the storage box 10.

[0053] In addition, the rubber 401 can also serve to reduce the impact on the worker's back (e.g., around the waist) when the worker carries the storage box 10 like a backpack, as will be described later in Figure 7.

[0054] Furthermore, the rubber 401 does not need to be continuously present in the X-axis direction below the back surface of the storage box 10 as illustrated in Figure 4, but may be limited to the part that comes into contact with the tree 500 when tightened and fixed by the belt 120, for example.

[0055] Next, referring to Figure 7, we will explain how to use the belt 120 attached to the back of the storage box 10, comparing (a) when the storage box 10 is attached to a tree 500 and (b) when the storage box 10 is carried on the back.

[0056] 7(a) is a diagram equivalent to FIG. 4, and is a diagram schematically illustrating the appearance of the back of the storage box 10 when the storage box 10 is attached to a tree 500. FIG. 7(b) is a diagram schematically illustrating the appearance of the back of the storage box 10 when the storage box 10 is carried on the back. As is clear from a comparison of FIG. 7(a) and FIG. 7(b), the belt 120 can be used as a belt for fastening and fixing the storage box 10 when it is attached to the tree 500, and can be used as a shoulder belt for the storage box 10 when it is carried on the back.

[0057] For example, when carrying the storage box 10 on one's back, as shown in Fig. 7(b), the belt 120 is fastened in a so-called "cross-body" manner by passing through the gap 202 (see Fig. 4(b)) (alternatively or additionally, hole 201) between the mounting bracket 112 and the guide bracket 200 and the inner space of the U-shaped handle 104 attached to the mounting bracket 114. The belt 120 is a ratchet belt, so that the length can be easily adjusted as a shoulder belt.

[0058] 7(b) 。 For example, a structure may be adopted as an attachment structure for belt 120 when converted into a shoulder belt, in which holes (not shown) for passing the free end of belt 120 are provided near both ends of mounting metal fitting 114 in the X-axis direction, and the free end of belt 120 is fastened and locked to these holes.

[0059] As described above, according to the storage box 10 of this embodiment, wireless devices such as the radio 301, the router 303, and the PoE injector 305 can be stored together in the storage box 10, making it easy to install, move, remove, etc. the wireless devices at work sites such as forestry, for example.

[0060] Furthermore, since the storage box 10 can be easily fastened and fixed to, for example, a tree 500 using the resin belt 120 provided on the back of the storage box 10, the installation location of the wireless devices (including the tree itself, its thickness, and its height) can be selected relatively freely. For example, the wireless devices can be easily installed in a location that does not interfere with work vehicles, such as on a forest road. Furthermore, it is easy to remove or relocate all the installed wireless devices together.

[0061] Furthermore, since rubber 401 is provided on the lower back surface of the storage box 10, the storage box 10 can be prevented from slipping off even when it is fastened and fixed at one point by the belt 120 provided on the upper back surface of the storage box 10.

[0062] Furthermore, by making the belt 120 out of resin, the risk of damaging the tree 500 to which the storage box 10 is attached can be reduced. Furthermore, the belt 120 can be converted into a shoulder belt, making it easy for workers to carry the storage box 10 on their backs. Because the storage box 10 can be carried on the back, both hands of the carrier are free, even at work sites where the footing is poor, such as unpaved forest roads, and there is a risk of falling, and the storage box 10 can be safely transported.

[0063] Furthermore, the storage box 10 is also provided with a handle 104, which allows one person to easily carry all the wireless devices together. In other words, the storage box 10 can be carried both by using the handle 104 and by using the belt 120 as a shoulder belt, allowing the storage box 10 to be carried in a manner suitable for the situation at the work site, for example. However, if it is sufficient to support only one of the modes of transportation, the handle 104 may be omitted, and the structure for fastening the free end of the belt 120 to the mounting bracket 114 (see FIG. 7(b)) may be omitted.

[0064] Furthermore, since fixing bands are used to fix wireless devices inside the storage box 10, the workload and time required for replacement work due to, for example, failure of wireless devices, upgrades, introduction of new products, etc. can be reduced, thereby improving work efficiency.

[0065] Furthermore, by fastening the wireless devices to the circuit board 122 provided inside the housing box 10 with a fastening band, it is possible to reduce the number of screw fastening points to the inner wall of the case 102. Therefore, for example, in cold regions where the temperature drops below freezing, it is possible to prevent damage to resin materials such as plastic at screw fastening points.

[0066] Furthermore, by using a non-metallic material such as wood or resin for board 122, it is possible to easily change the screw fastening positions on board 122 for the fixing band attachment portions. Therefore, it is possible to flexibly change the number and / or arrangement of fastening points on board 122 using fixing bands, and it is also possible to flexibly accommodate size changes associated with, for example, replacing wireless devices housed in case 102.

[0067] <Example of wireless network system construction using storage box 10> Next, with reference to FIG. 8, an example in which one or more accommodation boxes 10 are installed to construct a wireless network system 800 will be described.

[0068] As illustrated in FIG. 8, by installing N (N is an integer greater than or equal to 1, and N=3 in FIG. 8) storage boxes 10-1 to 10-N containing the wireless devices illustrated in FIG. 2 at multiple locations, a wireless network system 800 having N wireless (e.g., WiFi) APs 10-i (i is any one of 1 to N) is constructed.

[0069] For example, in a forestry work site, there are many trees 500 along the forest road. By attaching a storage box 10-i to each of the different trees 500 as shown in Fig. 5, it is possible to easily build a wireless network system 800 that does not interfere with work vehicles using the forest road.

[0070] An external power source (e.g., a portable power source) 806 is connected to each of the storage boxes 10-i via a power cable 503 (see FIG. 2), and power is supplied to the wireless devices stored in the storage box 10-i from the external power source 806. Each of the storage boxes 10-i forms a wireless area (e.g., a WiFi area) 801-i as a wireless AP.

[0071] Any one of the wireless APs 10-i (for example, the wireless AP 10-1) is connected to a gateway (GW) device such as the Internet connection device 802 by wire (for example, the LAN cable 501 shown in FIG. 2) or wirelessly (for example, the wireless device 301 shown in FIG. 2). The wireless APs 10-i are connected via a wireless relay connection via a wireless link 808. The wireless relay connection may be, for example, a multi-hop connection or a mesh connection.

[0072] The internet connection device 802 provides, for example, a communication connection with a WAN (e.g., the internet) 804. The internet connection device 802 may include, for example, a router for cellular communication such as 3G (Generation), 4G, 5G, or 6G (or beyond 5G), a router for a non-terrestrial network (NTN), and / or a home gateway.

[0073] The NTN may illustratively include a communications network utilizing at least one of geostationary orbit satellites (GEO), low earth orbit satellites (LEO), and high-altitude platform stations (HAPS).
