Description

Technical Field

[0001] The present invention relates to a moving vehicle. Specifically, for example, it relates to a moving vehicle for providing information to the surroundings both in normal times and during disasters.

Background Art

[0002] When disasters such as earthquakes, typhoons, and heavy rain occur, lifelines such as electricity, water supply, city gas, and communication stop, and the social impact is serious. Even if there is no damage to houses or human casualties during a disaster, if the lifeline stops, it will cause problems in life.

[0003] Among the lifelines, electricity is essential for daily life. During a power outage, household electrical appliances such as TVs and refrigerators, so-called home appliances, cannot be used. At night, lighting fixtures cannot be used, so one has to live in the dark. In the event of an earthquake disaster, furniture may fall and objects may scatter, which is dangerous. For small children, just being in the dark can be scary. Also, the refrigerator cannot be used, especially in summer, food will spoil, and the IH cooker cannot be used either, so hot water cannot be boiled.

[0004] Therefore, various technologies have been proposed for countermeasures when a power outage occurs due to a disaster. For example, Patent Document 1 describes a power supply support system that can prevent the stagnation of power supply to the premises of an apartment building that adopts collective power reception when a power outage occurs.

[0005] The power supply support system described in Patent Document 1 includes a processing device, and this processing device acquires disaster information via a network from a collection server that collects disaster information related to earthquakes, fires, floods, volcanic eruptions, and other disasters. The processing device predicts the occurrence of a power outage within a predetermined future time based on the acquired disaster information, determines the charging and discharging schedules for the battery equipment based on the results of this prediction, and controls the charging and discharging of the battery equipment according to the determined schedules.

Summary of the Invention

Problems to be Solved by the Invention

[0007] By the way, in depopulated areas with a small population, there are few condominiums constructed, and houses are scattered. Therefore, when a disaster such as an earthquake occurs and it is difficult to obtain disaster information on one's own due to a power outage or communication failure, there has been a problem that it is difficult for nearby residents to share disaster information with each other and the disaster information is difficult to spread. Therefore, paying attention to the fact that vehicles such as water supply trucks enter and operate in the disaster area even during a disaster, the present invention has been completed.

[0008] The present invention was devised in view of the above points, and an object thereof is to provide a moving vehicle capable of spreading information to residents during a disaster.

Means for Solving the Problems

[0009] In order to achieve the above object, the moving vehicle of the present invention is a moving vehicle including a main body configured in a truck type with a cargo compartment attached to a loading platform, and wheels attached to the main body, and includes a display unit attached to an outer surface of the cargo compartment that is substantially orthogonal to a horizontal plane and capable of displaying predetermined information, and a power generation unit disposed in the cargo compartment and capable of supplying power.

[0010] Here, it is attached to the outer surface of the luggage compartment of the main body to which the wheels are attached, which is substantially orthogonal to the horizontal plane, and the display unit capable of displaying predetermined information can show the predetermined information to people around while changing the location.

[0011] Also, it is attached to the luggage compartment, and the power generation unit capable of supplying power can supply power to the display unit, charge electrical equipment, or supply power to cooking equipment to start cooking during a disaster.

[0012] Moreover, the moving vehicle of the present invention includes a state determination unit capable of determining whether the main body is in a moving state or a stopped state, and when the state determination unit determines that the main body is in a moving state, the display unit can be controlled to display a still image on the display unit, and when the state determination unit determines that the main body is in a stopped state, the display unit can be controlled to display a moving image on the display unit, and it can be configured to include a display control unit.

[0013] In this case, it is easy for people around to recognize the image displayed by the display unit.

[0014] In addition, in the moving vehicle of the present invention, the power generation unit can supply power to the display unit, and when the wireless communication unit can only perform low-speed wireless communication, the display control unit can control the display unit to reduce the area of the display area and display only character information in the display area with the reduced area.

[0015] Here, the "case where only low-speed wireless communication is possible" includes, for example, the case where a failure occurs in the existing high-speed wireless communication due to a disaster. In this case, during a disaster, limited power can be saved and information can be displayed on the display unit.

[0016] Further, the moving vehicle of the present invention includes a light detection unit capable of detecting the brightness of the surrounding environment of the display unit, and the display control unit controls the display unit to make the color tone of the image darker and increase the contrast on the display unit when the brightness detected by the light detection unit is greater than a predetermined value, and controls the display unit to make the color tone of the image lighter and decrease the contrast on the display unit when the brightness detected by the light detection unit is less than a predetermined value.

[0017] In this case, the display unit can clearly display the image whether the surrounding environment of the display unit is very bright or very dark.

[0018] Further, the moving vehicle of the present invention can be configured to include a wireless communication unit attached to the main body, capable of wireless communication with a communication terminal, and capable of transmitting and receiving radio waves in all directions.

[0019] In this case, the moving vehicle of the present invention can become a mobile base station vehicle constituting a wireless communication network. The communication terminal may be any device capable of wireless communication. For example, other moving vehicles of the present invention equipped with a wireless communication unit, digital signage, LED vision, communication base stations, smartphones, notebook computers, tablet terminals, drones equipped with communication terminals, servers, and communicable environmental sensors can be mentioned.

[0020] Further, in the moving vehicle of the present invention, the cargo compartment is configured in a rectangular parallelepiped shape, and the display unit can be configured to be attached to substantially the entire left outer surface, right outer surface, and rear outer surface of the cargo compartment.

[0021] In this case, combined with the light from the lighting lights attached to the front of the main body, it is possible to illuminate the four directions centered on the moving vehicle. Further, since the area of the display unit is large enough to be attached to substantially the entire outer surface of the cargo compartment, people around can confirm the information displayed on the display unit even from a distance.

[0022] In addition, in the moving vehicle of the present invention, the wireless communication unit can be configured to be capable of multi-hop communication with a communication terminal using the LPWA method.

[0023] In this case, since the communication terminal includes the moving vehicle of the present invention equipped with a wireless communication unit, a plurality of moving vehicles of the present invention can serve as base stations constituting a multi-hop network using the LPWA method, and even in a situation where a high-speed communication line such as an Internet line cannot be used during a disaster, low-speed communication over a wide area can be maintained.

[0024] Further, the moving vehicle of the present invention includes a wireless communication unit attached to the main body, capable of wireless communication with a communication terminal and capable of transmitting and receiving radio waves in all directions, and a positioning unit capable of positioning the position information of the main body. The wireless communication unit can transmit the position information measured by the positioning unit to the server and can receive advertisement information related to the position information from the server. The display control unit can control the display unit to display the advertisement information related to the position information on the display unit when the wireless communication unit transmits the position information to the server.

[0025] In this case, since advertisement information related to the area where the moving vehicle of the present invention is actually running can be displayed, efficient advertising can be realized.

Effects of the Invention

[0026] The moving vehicle according to the present invention can disseminate information to residents during a disaster.

Modes for Carrying Out the Invention

[0028] Hereinafter, embodiments of the present invention will be described with reference to the drawings to facilitate understanding of the present invention. FIG. 1 is a schematic left side view (a), a schematic right side view (b), and a schematic front view (c) showing an example of a mobile base station vehicle to which the present invention is applied.

[0029] The mobile base station vehicle 1 of the present invention shown in FIGS. 1(a), 1(b), and 1(c) includes a main body 2. Here, the main body 2 is configured in a truck type with a cargo compartment 2A attached to the loading platform. The main body 2 also has a cabin 2B for the driver to ride in, and the cabin 2B is connected to the loading platform. In addition, the mobile base station vehicle 1 of the present invention includes wheels 3 attached to the main body 2. The mobile base station vehicle 1 is an example of a mobile vehicle.

[0030] As shown in FIGS. 1(a), 1(b), and 1(c), the cargo compartment 2A is configured in a rectangular parallelepiped shape, and a space capable of accommodating articles and the like is formed inside the cargo compartment 2A.

[0031] The mobile base station vehicle 1 of the present invention also includes an LED vision 4. The LED vision 4 is an example of a display unit, and for example, a liquid crystal display panel can also be used as the display unit. Here, the LED vision 4 can display predetermined information, for example, advertisement information in normal times and disaster information in the event of a disaster. Of course, when a display unit such as the LED vision 4 displays information, sound is also output.

[0032] In addition, the LED vision 4 is a large display device composed of light-emitting diodes of three colors, "red", "blue", and "green". As shown in FIGS. 1(a), 1(b), and 1(c), the LED vision 4 is configured by arranging a plurality of LED vision components 4A.

[0033] In addition, the LED vision 4 is attached to the outer surface of the cargo compartment 2A that is substantially orthogonal to the horizontal plane. That is, as shown in FIGS. 1(a), 1(b), and 1(c), the LED vision 4 is attached to substantially the entire surfaces of the left outer surface, right outer surface, and rear outer surface of the rectangular parallelepiped-shaped cargo compartment 2A.

[0034] In addition, since the LED vision 4 is attached to the outer surface of the cargo compartment 2A in this way, it has waterproof and dustproof resistance. Also, the information displayed by the LED vision 4 attached to the left outer surface of the cargo compartment 2A, the information displayed by the LED vision 4 attached to the right outer surface of the cargo compartment 2A, and the information displayed by the LED vision 4 attached to the rear outer surface of the cargo compartment 2A may be the same as or different from each other.

[0035] In addition, the mobile base station vehicle 1 of the present invention includes a power generation unit 5. Here, the power generation unit 5 is installed in the cargo compartment 2A as one of the in-vehicle devices 1A and can supply power to the LED vision 4.

[0036] In addition, the mobile base station vehicle 1 of the present invention includes a wireless communication unit 6. Here, the wireless communication unit 6 is attached to the main body 2 and can perform wireless communication with a communication terminal. That is, the wireless communication unit 6 is composed of an antenna 6A and a communication device 6B. As shown in FIGS. 1(a), 1(b), and 1(c), the antenna 6A is attached to the upper outer surface (ceiling surface) of the cargo compartment 2A, and the communication device 6B is installed in the cargo compartment 2A as one of the in-vehicle devices 1A.

[0037] In addition, the wireless communication unit 6 can perform wireless communication with a communication terminal, such as high-speed wireless communication, for example, the third-generation mobile communication system (3G), LTE communication, the fourth-generation mobile communication system (4G), the fifth-generation mobile communication system (5G), Wi-Fi communication, and low-speed wireless communication, for example, LPWA communication, infrared communication. That is, the wireless communication unit 6 can perform LPWA communication and infrared communication with a communication terminal. Therefore, even when LPWA communication is impossible for some reason, the wireless communication unit 6 can perform infrared communication.

[0038] Here, as the communication terminal, any device capable of wireless communication may be used. For example, other mobile base station vehicles of the present invention equipped with a wireless communication unit, digital signage, LED vision, communication base stations, smartphones, notebook computers, tablet terminals, drones equipped with communication terminals, servers, and communicable environmental sensors may be mentioned. In addition, the "environmental sensor" means a sensor capable of acquiring environmental data such as rainfall, atmospheric pressure, and the inclination angle of a mountain slope. That is, the mobile base station vehicle 1 of the present invention equipped with the wireless communication unit 6 can also serve as a communication terminal with which other mobile base station vehicles of the present invention equipped with a wireless communication unit can communicate.

[0039] In addition, the wireless communication unit 6 can transmit and receive radio waves in all directions. Therefore, the wireless communication unit 6 can form a wireless communication area, and within the wireless communication area, communication terminals can perform wireless communication and calls.

[0040] In addition, the mobile base station vehicle 1 of the present invention is provided with a state determination unit 7. Here, the state determination unit 7 can determine whether the main body 2 is in a moving state or a stopped state. In addition, the state determination unit 7 is installed in the cargo compartment 2A as one of the in-vehicle devices 1A.

[0041] In addition, the mobile base station vehicle 1 of the present invention is provided with a recording unit 9. Here, the recording unit 9 can record information received by the wireless communication unit 6 from an external server, or can record information input via a storage medium. In addition, the recording unit 9 is installed in the cargo compartment 2A as one of the in-vehicle devices 1A.

[0042] In addition, since the mobile base station vehicle of the present invention equipped with the wireless communication unit 6 and other mobile base station vehicles of the present invention equipped with the wireless communication unit can communicate with each other, for example, LPWA communication, the mobile base station vehicle 1 of the present invention can transmit information received from an external server, such as disaster information, to other mobile base station vehicles of the present invention by LPWA multi-hop communication. Other mobile base station vehicles of the present invention can transmit the disaster information received from the mobile base station vehicle 1 of the present invention to still other mobile base station vehicles of the present invention by LPWA multi-hop communication. Then, the disaster information transmitted through a plurality of mobile base station vehicles of the present invention in this way is transmitted from the mobile base station vehicle of the present invention to a communication terminal, such as a digital signage, an LED vision, or a smartphone, by the LPWA method, and the received digital signage, LED vision, or smartphone displays the disaster information. Of course, each LED vision, that is, the display unit, of the mobile base station vehicle of the present invention that has received the disaster information can display the disaster information.

[0043] In this way, since a multi-hop network of the LPWA method can be constructed by a plurality of mobile base station vehicles of the present invention, it is possible to quickly construct a communication network in an area where no communication network has been constructed at all, or in an area where a communication network based on the fourth-generation mobile communication system (4G) or the fifth-generation mobile communication system (5G) has been constructed but a communication failure has occurred in the entire network due to a disaster.

[0044] Also, assume that a landslide disaster has occurred in an area where communication-capable environmental sensors, such as tilt angle sensors and rainfall sensors, installed on mountains or hills, transmit the acquired environmental data to a digital signage, an LED vision, a smartphone, a server, etc. using a fixed base station installed on the same mountain or hill, and the fixed base station has collapsed. Even in such a case, the mobile base station vehicle 1 of the present invention moves to the area where the landslide disaster has occurred, and the wireless communication unit 6 receives the environmental data acquired by each environmental sensor by LPWA multi-hop communication. Instead of the collapsed fixed base station, the environmental data can be transmitted to a digital signage, an LED vision, a smartphone, a server, etc. via a nearby communication network.

[0045] Also, one mobile base station vehicle 1 of the present invention moves to an area where there is no fixed base station or communicable environmental sensor, installs communicable environmental sensors such as an inclination angle sensor and a rainfall sensor to acquire environmental data, and the wireless communication unit 6 receives the environmental data acquired by each environmental sensor by LPWA multi-hop communication, and the environmental data can be transmitted to a digital signage, an LED vision, a smartphone, a server, etc. via a nearby communication network. In addition, the LED vision 4 of the mobile base station vehicle 1 of the present invention can display the environmental data acquired by each environmental sensor received by the wireless communication unit 6.

[0046] Further, the LED vision 4 which is a display unit can display the information recorded by the recording unit 9. Also, the LED vision 4 can display the information while the wireless communication unit 6 receives the information from a communication terminal such as a server.

[0047] In addition, the mobile base station vehicle 1 of the present invention includes a light detection unit 10. Here, the light detection unit 10 can detect the brightness of the surrounding environment of the LED vision 4. Also, the light detection unit 10 is installed outside the cargo compartment 2A as one of the in-vehicle devices 1A.

[0048] In addition, the mobile base station vehicle 1 of the present invention includes a display control unit 8. The display control unit 8 is installed inside the cargo compartment 2A as one of the in-vehicle devices 1A.

[0049] Here, when the state determination unit 7 determines that the main body 2 is in a moving state, the display control unit 8 can control the LED vision 4 to display a still image on the LED vision 4. When the state determination unit 7 determines that the main body 2 is in a stopped state, the display control unit 8 can control the LED vision 4 to display a moving image on the LED vision 4.

[0050] Further, when the wireless communication unit 6 can only perform low-speed wireless communication, for example, LPWA communication, the display control unit 8 can control the LED vision 4 to reduce the area of the display region on the LED vision 4 and display only character information in the display region of the LED vision 4 with the reduced area. For example, in the event of a disaster, when a high-speed wireless communication line such as an Internet line cannot be used, the wireless communication unit 6 performs LPWA communication, and the display control unit 8 reduces the area of the display region of the LED vision 4. For example, the display control unit 8 can control the LED vision 4 to display only character information on only the two LED vision components 4A closest to the cabin 2B.

[0051] Since the power generation unit 5 supplies power to the LED vision 4, in the event of a disaster with limited power, the display region of the LED vision 4 is limited to only the two LED vision components 4A closest to the cabin 2B to reduce the area of the display region, and only character information is displayed on only the two LED vision components 4A closest to the cabin 2B, thereby saving power and being able to display information.

[0052] In addition, when the brightness detected by the light detection unit 10 is greater than a predetermined value, the display control unit 8 can control the LED vision 4 to darken the color tone of the image and increase the contrast on the LED vision 4. In addition, when the brightness detected by the light detection unit 10 is less than a predetermined value, the display control unit 8 can control the LED vision 4 to lighten the color tone of the image and decrease the contrast on the LED vision 4.

[0053] Here, the "predetermined value" can be set in multiple stages, and accordingly, multiple levels of color tone darkness and contrast strength can also be set. Also, "contrast" means the ratio of brightness (luminance) between the white part and the black part on the screen of the LED vision 4, i.e., the display unit.

[0054] Moreover, the mobile base station vehicle 1 of the present invention can also be provided with an environmental sound detection unit. Here, the environmental sound detection unit can detect the volume of the environmental sound around the mobile base station vehicle 1 of the present invention. The volume is expressed in, for example, decibels. Then, the display control unit 8 can control the LED vision 4, i.e., the display unit, so that the image volume output together with the image is made equal to the volume of the environmental sound detected by the environmental sound detection unit, and while displaying the image, the image volume equal to the volume of the environmental sound is output.

[0055] Moreover, the mobile base station vehicle 1 of the present invention is provided with a positioning unit 11. Here, the positioning unit 11 can, for example, utilize GPS (Global Positioning System) to measure the position information of the main body 2 of the mobile base station vehicle 1 of the present invention at regular intervals, for example, at one-second intervals. The position information is composed of, for example, latitude information and longitude information.

[0056] Also, the wireless communication unit 6 can transmit the position information of the main body 2 of the mobile base station vehicle 1 of the present invention measured by the positioning unit 11 to the server. Also, the server is provided with an advertisement information recording unit, and the advertisement information recording unit can record advertisement information in association with each position information.

[0057] Also, the advertisement information recording unit can record advertisement information in association with each predetermined area specified by the latitude information within a predetermined range and the longitude information within a predetermined range. That is, the advertisement information recording unit can record advertisement information related to restaurants, amusement facilities, etc. existing in Kabukicho, Shinjuku-ku, Tokyo in association with the latitude information and longitude information of Kabukicho, Shinjuku-ku, and can record advertisement information related to department stores, etc. existing in Ginza in association with the latitude information and longitude information of Ginza, Chuo-ku, Tokyo.

[0058] Also, the server includes an advertisement information transmitting unit. Here, when position information is transmitted from the wireless communication unit 6, the advertisement information transmitting unit can select the advertisement information related to this position information from the advertisement information recording unit and transmit the selected advertisement information to the wireless communication unit 6.

[0059] Also, when the wireless communication unit 6 transmits position information to the server, the display control unit 8 can control the LED vision 4 to display the advertisement information received by the wireless communication unit 6 related to the transmitted position information on the LED vision 4.

[0060] That is, since the positioning unit 11 measures the position information of the main body 2 at one-second intervals, the wireless communication unit 6 also transmits the position information to the server at one-second intervals. On the other hand, the server also transmits, in response to this, the advertisement information related to the transmitted position information to the wireless communication unit 6, and the display control unit 8 displays the transmitted advertisement information on the LED vision 4. Therefore, while the mobile base station vehicle 1 of the present invention is running, when it exits one area and enters another area, the advertisement information displayed on the LED vision 4 switches from the advertisement information related to the position information of one area to the advertisement information related to the position information of the other area.

[0061] The LED vision 4 provided in the mobile base station vehicle 1 of the present invention does not necessarily have to be configured by arranging a plurality of LED vision components 4A. However, if the LED vision 4 is composed of a plurality of LED vision components 4A, it is preferable because the display control unit 8 can easily control the area of the display region of the LED vision 4.

[0062] Further, the LED vision 4 does not necessarily have to be attached to substantially the entire left outer surface, right outer surface, and rear outer surface of the cargo compartment 2A. For example, the LED vision 4 may be attached only to the left outer surface and the right outer surface. However, if the LED vision 4 is attached to substantially the entire left outer surface, right outer surface, and rear outer surface of the cargo compartment 2A, it is possible to illuminate all four directions centered around the mobile base station vehicle 1 of the present invention in combination with the light from the lighting light attached to the front of the main body 2. In addition, since the area of the LED vision 4 is large enough to be attached to substantially the entire outer surface of the cargo compartment 2A, people around can confirm the information displayed by the LED vision 4 even from a distance, which is preferable.

[0063] Further, the mobile base station vehicle 1 of the present invention does not necessarily have to be provided with the wireless communication unit 6. However, if the mobile base station vehicle 1 of the present invention is provided with the wireless communication unit 6, it can be a base station that constitutes a wireless communication network and can move, which is preferable.

[0064] Further, the wireless communication unit 6 does not necessarily have to be capable of multi-hop communication with the communication terminal using the LPWA method. However, if the wireless communication unit 6 is capable of multi-hop communication with the communication terminal using the LPWA method, since the communication terminal includes the mobile vehicle of the present invention provided with the wireless communication unit, a plurality of mobile base station vehicles of the present invention can be base stations that constitute a multi-hop network using the LPWA method, and even in a situation where a high-speed communication line such as an Internet line cannot be used during a disaster, it is possible to maintain low-speed communication over a wide range, which is preferable.

[0065] Further, the mobile base station vehicle 1 of the present invention does not necessarily have to be provided with the state determination unit 7, the display control unit 8, and the light detection unit 10.

[0066] However, if the mobile base station vehicle 1 of the present invention is provided with the state determination unit 7 and the display control unit 8, it is preferable because it is easy for people around to recognize the image displayed by the LED vision 4. In addition, if the mobile base station vehicle 1 of the present invention is provided with the display control unit 8, it is preferable because information can be displayed on the display unit while saving limited power in the event of a disaster. In addition, if the mobile base station vehicle 1 of the present invention is provided with the display control unit 8 and the light detection unit 10, it is preferable because the LED vision 4 can display an image clearly regardless of whether the surrounding environment of the LED vision 4 is very bright or very dark.

[0067] Further, the power generation unit 5, the communication device 6B, the state determination unit 7, the display control unit 8, and the recording unit 9 do not necessarily have to be installed in the cargo compartment 2A, and may be installed, for example, in the space under the driver's seat.

[0068] Next, the usage mode of the mobile base station vehicle 1 of the present invention will be described.

[0069] In normal times when no disaster has occurred, while the mobile base station vehicle 1 of the present invention is traveling on a road in an urban area, the LED visions 4 attached to substantially the entire outer left side surface, outer right side surface, and outer rear side surface of the cargo compartment 2A are controlled by the display control unit 8 to display still images such as advertisement information for products and services and event information. In addition, when the mobile base station vehicle 1 of the present invention is stopped on a road in an urban area, the LED vision 4 is controlled by the display control unit 8 to display moving images such as advertisement information for products and services and event information.

[0070] In this way, when the mobile base station vehicle 1 of the present invention is traveling, the LED vision 4 displays a still image, and when the mobile base station vehicle 1 of the present invention is stopped, the LED vision 4 displays a moving image. Therefore, the law can be complied with, and the images displayed by the LED vision 4 can be easily visually recognized by people around.

[0071] In addition, the mobile base station vehicle 1 of the present invention is provided with the light detection unit 10, and the brightness of the surrounding environment of the LED vision 4 is set in multiple stages, and accordingly, the darkness of the color tone and the strength of the contrast are also set in multiple stages. Therefore, when the mobile base station vehicle 1 of the present invention is traveling even during the day and enters the shade of a building from a place exposed to direct sunlight, the display control unit 8 controls the LED vision 4 to make the color tone of the image lighter and the contrast weaker. Also, when sunset approaches, the display control unit 8 controls the LED vision 4 to make the color tone of the image even lighter than the color tone of the image when it enters the shade of the building, and to make the contrast weaker than the contrast when it enters the shade of the building.

[0072] FIG. 2 is a schematic diagram showing an example of a state in which a mobile base station vehicle to which the present invention is applied constitutes a wireless communication network with a fixed base station. However, the mobile base station vehicle 1 of the present invention can move and constitute a wireless communication network instead of the fixed base station.

[0073] That is, as shown in FIG. 2, for example, when a disaster such as an earthquake occurs and the second fixed base station 22 among the first fixed base station 21, the second fixed base station 22, and the third fixed base station 23 that constitute the wireless communication network collapses, this will be described as an example.

[0074] In this case, the mobile base station vehicle 1 of the present invention moves close to the location where the second fixed base station 22 was installed, and the wireless communication unit 6 provided in the mobile base station vehicle 1 of the present invention forms a wireless communication area 200. Also, the first fixed base station 21 and the third fixed base station 23 also form a wireless communication area 200. Here, each of the wireless communication areas 200 is a spherical area with a radius of 1 to 10 km centered on each base station.

[0075] Also, when the disaster-stricken area of the earthquake is a depopulated area, houses are scattered and it is difficult for nearby residents to share disaster information. Therefore, the mobile base station vehicle 1 of the present invention can display disaster information on the LED vision 4 and tour the disaster-stricken area to spread the disaster information.

[0076] In addition, since the wireless communication unit 6 of the mobile base station vehicle 1 of the present invention forms a wireless communication area 200, the mobile base station vehicle 1 of the present invention can move to an area where a communication failure has occurred, enabling wireless communication of communication terminals such as smartphones held by the residents in that area.

[0077] Further, even if the first fixed base station 21, the second fixed base station 22, and the third fixed base station 23 are base stations that constitute an LPWA multi-hop network, the wireless communication unit 6 can perform multi-hop communication with a communication terminal using the LPWA method. Therefore, even if the second fixed base station 22 collapses, the mobile base station vehicle 1 of the present invention can move in and reconfigure the LPWA multi-hop network.

[0078] In addition, since the main body 2 of the mobile base station vehicle 1 of the present invention is configured in a truck type with a cargo compartment 2A attached to the loading platform, for example, in the event of a disaster, cooking equipment can be arranged in the cargo compartment 2A, and the power generation unit 5 installed in the cargo compartment 2A can also supply power to the cooking equipment, enabling cooking to be performed in the cargo compartment 2A and distributing the cooked food to the residents in the disaster area. Also, since the disaster area has a power shortage, the power generation unit 5 can be used to charge the electrical equipment held by the residents.
