Description

An application for the application of Article 30, Paragraph 2 of the Patent Law was filed. It was exhibited at JECA FAIR 2024 (the 72nd Electrical Construction Industry Exhibition) from May 29th to 31st, 2024. This disclosure relates to an access point device and a wireless communication system. Communication equipment used for communication within tunnels is disclosed (see, for example, Patent Document 1). The communication equipment disclosed in Patent Document 1 is used in power cable laying work, where multiple workers sequentially feed power cables shorter than the tunnel length into the tunnel. Japanese Patent Publication No. 2000-312416 Figure 1 is a schematic perspective view showing the external appearance of the access point device.Figure 2 is a schematic perspective view showing the internal structure of the access point device.Figure 3 is a schematic perspective view showing the access point device installed inside the tunnel.Figure 4 is a schematic perspective view showing the access point device installed inside the tunnel.Figure 5 is a schematic diagram showing an overview of a wireless communication system used when laying power cables inside a tunnel.Figure 6 is a schematic diagram showing the configuration of a wireless communication system used when laying power cables inside a tunnel. [Description of Embodiments in this Disclosure] (1) The access point device relating to this disclosure is used as a wireless communication device. The access point device comprises a housing, a hub located inside the housing, and an antenna located outside the housing. The housing is provided with an opening for a communication cable, through which a communication cable connected to the hub can be routed to the outside of the housing. The access point device according to this disclosure includes a hub, allowing a wired communication cable to be connected to the hub, thereby ensuring a communication environment. In some cases, the access point device may be installed, for example, inside a tunnel. Tunnels often have high humidity. In this case, since the hub is located inside the enclosure, it is easy to keep the electronic device, the hub, separate from the high-humidity environment. The enclosure is provided with an opening for communication cables, allowing for cable routing and ensuring connectivity using communication cables while avoiding exposure of the hub to external environments such as high humidity. Furthermore, tunnels may contain numerous existing lines, potentially generating a lot of noise that negatively impacts the electronic device, the hub. Even in such cases, the presence of the hub inside the enclosure reduces the impact of noise. Additionally, since the antenna is located outside the enclosure, efficient transmission and reception of radio waves are possible. Therefore, the access point device according to this disclosure makes it easy to ensure an efficient communication environment. (2) In (1) above, the antenna angle may be variable. This allows, for example, when installing an access point device inside a tunnel, the antenna angle to be changed according to the shape of the tunnel. Therefore, the antenna angle can be adjusted to ensure more reliable transmission and reception of radio waves, making it easier to secure an efficient communication environment. (3) In (1) or (2) above, the antenna may include a planar antenna. Such an antenna can significantly reduce the risk of collapse when installed and is therefore good from a safety standpoint. (4) In any of the above (1) to (3), the antenna may be rotatable about the first axis of rotation. This allows the antenna's angle to be changed by rotating it about the first axis of rotation. Therefore, it becomes easy to flexibly change the antenna's orientation to match the shape of the tunnel. (5) In any of (1) to (4) above, the antenna may be rotatable around a first rotation axis and a second rotation axis extending in a direction intersecting the first rotation axis. This allows for a wider range of changes in the antenna's angle by rotating it around the first and second rotation axes. Therefore, it becomes easier to more flexibly change the antenna's orientation to match the shape of the tunnel. (6) In any of the above (1) to (3), the antenna may be rotatable by a ball joint. This allows the angle of the antenna to be changed to a desired direction using the ball joint. Therefore, it becomes easier to more flexibly change the antenna's orientation to match the shape of the tunnel. (7) In any of the above (1) to (6), the hub may be detachably mounted on the housing. This makes it easy to replace the hub. Furthermore, the hub can be removed when mounting the housing, and then attached after the housing is mounted. Therefore, convenience during the installation of the access point device can be improved. (8) In any of the above (1) to (7), a battery may be further provided, which is located inside the enclosure and supplies power to
