[0003] [Patent Document 1] JP 2006-233503 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, for example, when guiding people to evacuation shelters in the event of a disaster, or when guiding people to reduce congestion around facilities, more efficient guidance and management of people may be required. With a road marking device that simply guides pedestrians walking at night as described in Patent Document 1, it may be difficult to achieve both efficient guidance and management of people.

[0005] The present disclosure has been made in consideration of the above-mentioned reasons, and aims to provide a street light and guidance system that can easily achieve efficient people guidance and management. [Means for solving the problem]

[0006] A street lamp according to one aspect of the present disclosure includes a pole, an illumination lamp, a communication unit, a receiving unit, and a control unit. The illumination lamp is provided on the pole. The communication unit communicates with a management device. The receiving unit receives an identification signal including identification information from a terminal present within a certain range. The control unit controls the illumination lamp, the communication unit, and the receiving unit. The illumination lamp has, as operation modes, an illumination lighting mode for illuminating the periphery of the pole, and an induction lighting mode for guiding a user of the terminal. When the communication unit receives a guidance instruction signal from the management device, the control unit operates the illumination lamp in the induction lighting mode and switches the state of the receiving unit to a state capable of receiving the identification signal from the terminal. When the receiving unit receives the identification signal, the control unit transmits a signal based on the identification information from the communication unit to the management device.

[0007] A guidance system according to an embodiment of the present disclosure includes one or more of the street lights described above, and the management device that transmits the guidance instruction signal to the one or more street lights. The guidance system determines a shelter to be a guidance destination based on shelter information regarding one or more shelters in response to the occurrence of an event requiring evacuation. The management device transmits the guidance instruction signal to the one or more street lights so as to guide the user to the determined shelter as a guidance destination by the guidance lighting mode.

[0008] A guidance system according to another aspect of the present disclosure includes one or more of the street lights described above, and the management device that transmits the guidance instruction signal to the one or more street lights. The one or more street lights are installed around an entrance / exit of a facility. The management device transmits the guidance instruction signal to the one or more street lights so as to guide the user to enter / exit the facility in the guidance lighting mode within a predetermined period of time, and manages the identification information received from the one or more street lights.

[Figure 13] FIG. 13 is a sequence diagram for explaining an example of operation in the above modification 1. In FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] (overview) Hereinafter, street lights and guidance systems according to embodiments and modifications will be described with reference to the drawings. Note that the following embodiment and modifications are merely one of various embodiments of the present disclosure. In addition, the following embodiment and modifications can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. In addition, the configurations of the modifications can be appropriately combined.

[0012] The drawings described in the following embodiments and modified examples are schematic drawings, and the ratios of sizes and thicknesses of the components do not necessarily reflect the actual dimensional ratios.

[0013] As shown in Fig. 5, a street light 1 according to one embodiment includes a pole 11 (see Fig. 2), an illumination lamp 12, a communication unit 13, a receiving unit 14, and a control unit 15. As shown in Fig. 1, the street light 1 may be installed facing a road (R1, R2, R3).

[0014] As shown in Fig. 2, the illumination lamp 12 is provided on a support pole 11. The communication unit 13 communicates with a management device 30 (or the management device 8 in Modification 1). The management device 30 may be installed in, for example, a management center 3 (see Fig. 1), and the management device 8 may be installed in, for example, a facility 6 such as an event venue 60 (see Fig. 10).

[0015] The receiving unit 14 receives an identification signal including identification information from a terminal 2 present within a certain range. The terminal 2 is a mobile terminal carried by a walking user (such as the evacuee H1 shown in FIG. 1 or the participant H3 shown in FIG. 10). The terminal 2 is assumed to be a mobile phone (a smartphone, as an example). The terminal 2 may be a wearable terminal that the user wears on the wrist or the like. Furthermore, the terminal 2 is not limited to being carried by a walking user, and may be mounted on a vehicle (such as an automobile or a motorcycle) driven by the user.

[0016] The control unit 15 controls the illumination lamp 12, the communication unit 13, and the receiving unit 14. The illumination lamp 12 has, as operation modes, an illumination lighting mode for illuminating the periphery of the support pole 11, and a guidance lighting mode for guiding users of the terminal 2 (evacuee H1, participant H3).

[0017] When the control unit 15 receives a guidance instruction signal from the management device 30 (or the management device 8) via the communication unit 13, it operates the illuminating lamp 12 in the guidance lighting mode and switches the state of the receiving unit 14 to a state where it can receive an identification signal from the terminal 2. In other words, the control unit 15 does not operate the illuminating lamp 12 in the guidance lighting mode and does not receive an identification signal from the terminal 2 until it receives a guidance instruction signal from the management device 30 (or the management device 8). Therefore, the street light 1 receives the identification signal from the terminal 2 only within a somewhat limited period of time.

[0018] When the control unit 15 receives the identification signal at the receiving unit 14, the control unit 15 transmits a signal based on the identification information (a management signal, described later) from the communication unit 13 to the management device 30 (or the management device 8). The identification information is, for example, information for identifying the user of the terminal 2, and is preferably registered and managed on the management center 3 side or on the facility 6 side, such as the event venue 60.

[0019] According to this configuration, while guiding the user of the terminal 2 (evacuee H1, participant H3) in the guidance lighting mode, it is possible to obtain identification information to be transmitted to the management device 30 (or management device 8) from the terminal 2 of the user. As a result, the street light 1 has the advantage of being able to easily realize efficient guidance and management of people.

[0020] 1, a guidance system 100 according to one embodiment includes one or more street lights 1 and a management device 30 that transmits a guidance instruction signal to the one or more street lights 1. In response to the occurrence of an event requiring evacuation, the guidance system 100 determines a shelter 4 to be guided to based on evacuation shelter information regarding one or more shelters 4. The "event requiring evacuation" referred to here is, for example, a natural disaster such as an earthquake, heavy rain, typhoon, flood, landslide, or tsunami, or a situation in which damage to human life and social life occurs due to a man-made cause.

[0021] The management device 30 transmits a guidance instruction signal to one or more street lights 1 so as to guide the user (evacuee H1 shown in FIG. 1) to the evacuation shelter 4 determined as the guide destination in the guidance lighting mode.

[0022] According to this configuration, while guiding the user (evacuee H1) of the terminal 2 in the guidance lighting mode, it is possible to obtain identification information to be transmitted to the management device 30 from the terminal 2 of the user. As a result, the guidance system 100 has an advantage that it can easily realize efficient guidance and management of people (evacuee H1).

[0023] Moreover, a guidance system 100A (see FIG. 10) according to another embodiment includes one or more of the street lights 1, and a management device 8 (see FIG. 11) that transmits a guidance instruction signal to the one or more street lights 1. The one or more street lights 1 are installed around the entrances and exits (gates 61 to 64: see FIG. 10) of a facility 6. In the example of FIG. 10, the facility 6 is an event venue 60, and in this case, the user may correspond to a participant H3 who participates in the event. Note that the term "entrance" here is a general term that includes not only the case where the entrance and the exit are the same, but also the case where the entrance and the exit are separate. In the example of FIG. 10, the entrance and the exit are separate, but these are collectively called a gate (entrance and exit).

[0024] The management device 8 transmits a guidance instruction signal to one or more street lights 1 to guide the user (participant H3) in entering / exiting the facility 6 in the guidance lighting mode within a specified period of time, and manages the identification information received from the one or more street lights 1.

[0025] According to this configuration, while guiding the user (participant H3) of the terminal 2 in the guidance lighting mode, it is possible to obtain the identification information to be transmitted to the management device 8 from the terminal 2 of the user. As a result, the guidance system 100A has an advantage that it is easy to realize efficient guidance and management of a person (participant H3).

[0026] (detail) (1) Overall structure Hereinafter, the street lamp 1 according to this embodiment, the guidance system 100, and the entire system including the peripheral configuration will be described in detail with reference to FIG.

[0027] The guidance system 100 includes one or more (six as an example in FIG. 1) street lights 1 and a management device 30. In the present embodiment, as an example, it is assumed that the guidance system 100 is applied as an evacuation guidance system. The guidance system 100 further includes one or more evacuation shelter devices 40 (two as an example in FIG. 1) that communicate with the management device 30.

[0028] FIG. 1 shows a state where a user (evacuee H1) evacuates when a natural disaster such as a typhoon occurs (or before the occurrence). The evacuee H1 is a resident of a village A1 where multiple houses are gathered. FIG. 1 shows a state where the evacuee H1 is walking toward a T-junction (roads R1, R2, R3). Specifically, the evacuee H1 is trying to move to a shelter 4A at the end of road R2 through roads R1 and R2. A road R3 branches off from the junction of roads R1 and R2, and another shelter 4B is installed at the end of road R3. In the following, when the shelter 4A and the shelter 4B are not distinguished from each other, they may be simply called the shelter 4. The shelter 4 may be a designated shelter such as a public facility that meets the standards set by government ordinance. The shelter 4A and the shelter 4B are, for example, a community center.

[0029] In the example of Fig. 1, six street lights 1 (1A, 1B, 1C, 1D, 1E, 1F) are installed. Specifically, street light 1A is installed facing road R1 to illuminate road R1, and street light 1B is installed facing the T-junction to illuminate the T-junction where road R1 branches into roads R2 and R3. Street lights 1C and 1D are installed side by side facing road R2 to illuminate road R2, and street lights 1E and 1F are installed side by side facing road R3 to illuminate road R3.

[0030] For the sake of convenience, the direction along road R1 is defined as the north-south direction, and the direction of "D1" in Fig. 1 is defined as the north direction. The direction along roads R2 and R3 is defined as the east-west direction, and the direction of "D2" in Fig. 1 is defined as the east direction.

[0031] In the example of Fig. 1, each of the six street lights 1 can communicate, for example, wirelessly with a management device 30 installed in a management center 3. Although the wireless method is not particularly limited, each street light 1 can communicate with the management device 30, for example, via a wide area network such as the Internet.

[0032] The management center 3 is a facility that manages residents and the like within a management area including the settlement A1. The management center 3 may be a city, ward, town or village office (for example, a city hall).

[0033] In addition, the shelter device 40 installed in each shelter 4 can also communicate with the management device 30, for example, wirelessly. Although the wireless method is not particularly limited, each shelter device 40 can communicate with the management device 30, for example, via a wide area network such as the Internet.

[0034] In addition, the management device 30 of the management center 3 is capable of wireless communication with a base station 5 (see FIG. 1) of a communication carrier company. The base station 5 is capable of wireless communication with a terminal 2 (e.g., a mobile phone such as a smartphone) carried by the evacuee H1.

[0035] (2) Street lights The street lamps 1A to 1F have substantially the same basic structure. Here, the configuration of the street lamp 1 will be described in detail with reference to FIGS.

[0036] 2 and 5, the street light 1 includes a pole 11, an illumination lamp 12, a communication unit 13, a receiving unit 14, and a control unit 15. The street light 1 further includes an illuminance sensor 16, a memory unit 17, a power supply unit 18, and a battery 19.

[0037] The support pillar 11 is pole-shaped. The support pillar 11 is installed so as to stand upright from the ground beside the road (R1 to R3). A storage unit is provided at the bottom of the support pillar 11 for storing the communication unit 13, the receiving unit 14, the control unit 15, the memory unit 17, the power supply unit 18, the battery 19, etc. The storage unit may be a part of the support pillar 11, or may be provided separately from the support pillar 11 so as to be held by the support pillar 11.

[0038] The power supply unit 18 is electrically connected to a commercial power source AC1 and a battery 19 (see FIG. 5). In a normal state when no power outage occurs, the power supply unit 18 generates operating power for the street light 1 using power supplied from the commercial power source AC1. The battery 19 is, for example, a secondary battery. In a normal state, the power supply unit 18 can charge the battery 19 using power from the commercial power source AC1. On the other hand, in the event of a power outage, the power supply unit 18 generates operating power for the street light 1 using power supplied from the battery 19. Note that the street light 1 may be of a solar power generation type having a small solar panel mounted on the pole 11, and the power supply unit 18 may generate power using sunlight to generate operating power for the street light 1 and charge the battery 19.

[0039] The illuminating lamp 12 is provided on the support pole 11. Here, the illuminating lamp 12 is provided on the upper part of the support pole 11 as shown in FIG. 2. The illuminating lamp 12 is electrically connected to a control unit 15 (see FIG. 5). In addition to the above, the communication unit 13, the receiving unit 14, the illuminance sensor 16, the storage unit 17, and the power supply unit 18 are also electrically connected to the control unit 15 (see FIG. 5).

[0040] As shown in Figs. 2 and 3, the illuminating lamp 12 has a cover 120 and a light source 121. The cover 120 is opaque to light. The light source 121 includes a plurality of lighting elements 122 arranged in a plane below the cover 120 (see Fig. 3). In short, the cover 120 is arranged above the light source 121. Each of the lighting elements 122 is composed of an LED module having, for example, RGB LEDs. Fig. 3 is a schematic plan view of the illuminating lamp 12 as viewed from below. The lighting elements 122 are arranged in a matrix. In the example of Fig. 3, the illuminating lamp 12 has a circular shape when viewed from below, but the shape is not particularly limited and may be an elliptical shape or a rectangular shape.

[0041] Although detailed description will be omitted, the illuminating lamp 12 may have a reflective surface on the lower surface of the cover 120 facing the light source 121, which reflects the light emitted from the light source 121 toward the road. In addition, the illuminating lamp 12 may have a translucent lens cover on the lower side of the light source 121, which performs light distribution control so as to efficiently irradiate the light from the light source 121 toward the road.

[0042] The illuminating lamp 12 lights up the lighting element 122 to emit, for example, white light, and illuminates a part of the road (R1 to R3) spreading directly below it. In other words, the illuminating lamp 12 has an illumination lighting mode for illuminating the periphery of the support pole 11 as an operation mode.

[0043] Moreover, the illumination lamp 12 has, as an operation mode, a guide lighting mode for guiding the user of the terminal 2 (here, the evacuee H1).

[0044] In other words, the illuminating lamp 12 can be controlled by the control unit 15 to operate in an illumination lighting mode and an induction lighting mode.

[0045] Here, the control unit 15 will be described in detail. The control unit 15 includes a computer system having one or more processors and a memory. At least a part of the functions of the control unit 15 is realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided through a telecommunication line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card and provided.

[0046] The control unit 15 controls at least the illumination lamp 12, the communication unit 13, and the receiving unit 14. Here, the control unit 15 further controls the illuminance sensor 16, the storage unit 17, and the power supply unit 18.

[0047] When the control unit 15 receives a guidance instruction signal from the management device 30 via the communication unit 13, it operates the illumination lamp 12 in a guidance lighting mode and switches the state of the receiving unit 14 to a state where it can receive an identification signal from the terminal 2.

[0048] When the receiver 14 receives the identification signal including the identification information, the controller 15 transmits a signal based on the identification information from the communication unit 13 to the management device 30 .

[0049] The communication unit 13 has a communication interface for communicating with the management device 30, for example, wirelessly. The communication between the communication unit 13 and the management device 30 may be performed in a form including a wired connection in part. The communication unit 13 has a function of communicating bidirectionally with the management device 30, for example, via a wide area network such as the Internet. The communication unit 13 receives a guidance instruction signal from the management device 30. The communication unit 13 may also receive signals other than the guidance instruction signal from the management device 30. The communication unit 13 also transmits a signal (hereinafter sometimes referred to as a "management signal") including identification information of the terminal 2 and information for identifying the device itself (street light 1) (street light ID information) to the management device 30. The management signal is a signal based on the identification information. The communication unit 13 may also transmit signals other than the management signal to the management device 30. The street light ID information is information unique to each street light 1 and is different between multiple street lights 1.

[0050] Any one of the communication units 13 of the multiple street lights 1 may function as a parent unit, and the others may function as child units. In this case, the communication unit 13 of the child unit may receive a guidance instruction signal from the management device 30 and transmit a management signal to the management device 30 via the communication unit 13 of the parent unit.

[0051] The receiving unit 14 receives an identification signal including identification information from a terminal 2 existing within a certain range. The receiving unit 14 has a communication interface for receiving the identification signal from the terminal 2 through short-range wireless communication with the terminal 2. The short-range wireless communication method may be, for example, a wireless communication method conforming to standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or low-power wireless that does not require a license (specified low-power wireless).

[0052] In this embodiment, the control unit 15 does not always activate the receiving unit 14. Only when the control unit 15 receives a guidance instruction signal from the management device 30 via the communication unit 13, the control unit 15 activates the receiving unit 14, establishes wireless communication of the receiving unit 14 with the terminal 2 that is present within a certain range, and causes the receiving unit 14 to receive an identification signal.

[0053] The storage unit 17 includes an electrically rewritable non-volatile semiconductor memory such as a flash memory. The storage unit 17 stores, for example, street light ID information of the device itself (street light 1). The storage unit 17 may be a memory of the control unit 15.

[0054] [Induction lighting mode] Next, the induction lighting mode will be described in detail.

[0055] 4A and 4B, as an example in the present embodiment, the guidance lighting mode includes an execution period in which the illuminating lamp 12 lights up and displays arrows (Y1, Y2) indicating specific directions (D1, D2) for guiding the user. The illuminating lamp 12 lights up and displays the arrows (Y1, Y2) by continuous lighting, but may also light up and display the arrows by blinking, as described later.

[0056] Figures 4A and 4B are schematic plan views of a road surface R0 of a road (R1 to R3) illuminated by the illuminating lamps 12 when the illuminating lamps 12 are operating in the induction lighting mode. Figure 4A shows an example of the road surface R0 on which an arrow Y1 is illuminated and displayed by the illuminating lamps 12 of each of the street lamps 1A and 1B (see Figure 1), and Figure 4B shows an example of the road surface R0 on which an arrow Y2 is illuminated and displayed by the illuminating lamps 12 of each of the street lamps 1C and 1D (see Figure 1).

[0057] Specifically, in Figures 4A and 4B, a substantially circular illumination area Z1 including a first illumination area 12a (hereinafter sometimes referred to as "road marking 7") and two second illumination areas 12b is projected onto the road surface R0 to provide the road marking 7.

[0058] The first illumination area 12a is an illumination area of ​​a specific color (e.g., red). The illuminating lamp 12 provides a road marking 7 on the road surface R0 by lighting some of the illumination elements 122 (hereinafter, sometimes referred to as a "first illumination section"), among the plurality of illumination elements 122 arranged in a plane, in a specific color.

[0059] 4A, the first illumination area 12a forms an isosceles triangle with an arrow Y1 whose apex points to a specific direction D1 (north). The street lamps 12 of the street lamps 1A and 1B have one or more illumination elements 122, among a plurality of illumination elements 122 arranged in a plane, that are lit in a specific color at a position corresponding to the shape and direction of the arrow Y1.

[0060] In Fig. 4B, the first illumination area 12a forms an isosceles triangle with an arrow Y2 whose apex points to a specific direction D2 (eastward). The street lamps 12 of the street lamps 1C and 1D have one or more illumination elements 122, among a plurality of illumination elements 122 arranged in a plane, illuminated in a specific color at a position corresponding to the shape and direction of the arrow Y2. Note that although the arrows Y1 and Y2 have different directions, they have the same shape and dimensions.

[0061] In this embodiment, each street light 1 is configured to provide a road marking 7 indicating one of a plurality of specific directions (e.g., eight directions of 0 degrees, 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees, and 315 degrees) relative to a 360-degree direction (azimuth) centered on the street light 1 itself. Each street light 1 is installed, for example, so that the directions of 0 degrees and 180 degrees are along the traveling direction of the road. For example, the street light 1A is installed so that 0 degrees faces the north direction and 180 degrees faces the south direction with respect to the road R1 that runs north and south. Information on the installation orientation of each street light 1 relative to the road is managed by the management device 30. Each street light 1 changes the position of the lighting element 122 that is lit in a specific color so as to provide a road marking 7 indicating a specific direction corresponding to a guidance instruction signal from the management device 30 among a plurality of specific directions.

[0062] The management device 30 manages installation information related to the installation position (coordinates) and installation direction of each street light 1 together with street light ID information of the street light 1. The management device 30 stores map information including, for example, the installation information of the street light 1, the position information of the road, and the position information of the evacuation shelter 4. For example, when the evacuation shelter 4A is the guide destination, the management device 30 determines, based on the map information, in which direction the road marking 7 of the street light 1A arranged facing the road R1 should be displayed, and transmits a guidance instruction signal including information indicating the determined direction to the street light 1A. In other words, the management device 30 determines and indicates the direction of the road marking 7 provided by the street light 1 individually for each street light 1 according to the location of the evacuation shelter 4 to be guided.

[0063] The specific directions D1, D2 illustrated in Figures 4A and 4B correspond to the specific directions D1, D2 illustrated in Figure 1. In Figure 1, the guidance system 100 provides road markings 7 indicating a specific direction D1 (north direction) from street lights 1A and 1B, and provides road markings 7 indicating a specific direction D2 (east direction) from street lights 1C and 1D, in order to guide an evacuee H1 to a shelter 4A.

[0064] Although detailed description is omitted, if the evacuation shelter 4B is also in a state capable of accommodating evacuees, the guidance system 100 may provide road markings 7 indicating an eastward direction from the street lights 1E and 1F to guide the evacuees to the nearest evacuation shelter 4B. Alternatively, the guidance system 100 may provide road markings 7 indicating a westward direction from the street lights 1E and 1F to guide the evacuees to the evacuation shelter 4A instead of the evacuation shelter 4B.

[0065] The guidance system 100 can also provide road markings 7 indicating the north direction from street light 1A, the east direction from street light 1B, and the west direction from street lights 1C and 1D, in order to guide the user to the evacuation shelter 4B.

[0066] The two second illumination areas 12b are areas on both sides of the first illumination area 12a in the substantially circular illumination area Z1. The second illumination area 12b is an illumination area of ​​a color (for example, white) different from the above-mentioned specific color. That is, the illuminating lamp 12 lights up the remaining illumination elements 122 (hereinafter, sometimes referred to as "second illumination units") other than the above-mentioned first illumination unit among the multiple illumination elements 122 arranged in a plane in white, similar to the illumination lighting mode that is the normal illumination state. Therefore, even when the street lamp 1 is operating in the induction lighting mode that provides the road markings 7, it can ensure a certain level of brightness for the evacuees H1 moving along the roads (R1 to R3).

[0067] However, the illumination area Z1 may include a dark area where the illumination light is not irradiated. For example, the illumination element 122 corresponding to the second illumination unit may be turned off in the induction lighting mode, and the second illumination area 12b of the illumination area Z1 may be a dark area where the illumination light is not irradiated.

[0068] In addition, in the illumination area Z1, the arrows Y1 and Y2 indicating the specific directions D1 and D2 may be an illumination area of ​​a color other than the specific color (e.g., white) or a dark area where no illumination light is irradiated. In this case, in the illumination area Z1, the periphery of the arrows Y1 and Y2 may be an illumination area of ​​a specific color (e.g., red).

[0069] In the above-mentioned induction lighting mode, the illumination lamp 12 continues the execution period in which the illumination lamp 12 lights up the arrows (Y1, Y2) indicating the specific directions (D1, D2) for guiding the user (providing the road markings 7) from the start to the end of the induction lighting mode. However, it is not essential that this execution period continues from the start to the end of the induction lighting mode. For example, the induction lighting mode may alternately include a first period in which illumination lighting for illuminating the periphery of the support pole 11 is performed and a second period in which induction lighting for guiding the user (evacuee H1) is performed. For example, the illumination lamp 12 may be lit so as to alternately include a first period in which all the illumination elements 122 are lit in white (i.e., the road markings 7 are not provided) and a second period in which the road markings 7 are provided (the execution period described above) from the start to the end of the induction lighting mode. In this case, it is preferable that the first period is longer than the second period. By making the first period longer than the second period, it is possible to suppress a decrease in the quality of the illumination provided by the street lamp 1 even when the user is being guided. In particular, by presenting the road markings 7 on the roads (R1 to R3) intermittently even if the presentation time for each is relatively short, it is possible to sufficiently inform the evacuee H1 of the direction in which to proceed.

[0070] Hereinafter, as one of the induction lighting modes, a mode including the above-mentioned first period and second period repeated alternately will also be referred to as a "dark induction lighting mode."

[0071] [Lighting mode and energy saving mode] Next, the illumination mode and the energy saving mode will be described in detail.

[0072] As described above, in this embodiment, the street lamp 1 includes the illuminance sensor 16. The illuminance sensor 16 detects the illuminance around the support pole 11. The illuminance sensor 16 is disposed on the support pole 11, for example. In this embodiment, the above-mentioned illumination mode is executed when the illuminance detected by the illuminance sensor 16 is equal to or lower than a reference value. Information regarding the reference value is stored in advance in the memory unit 17.

[0073] Here, the illuminating lamp 12 further has an energy saving mode as an operation mode in which the lamp is turned off or turned on at a low output when the illuminance detected by the illuminance sensor 16 is higher than a reference value.

[0074] In other words, the illuminating lamp 12 is basically turned off (or turned on at low power) during relatively bright times such as daytime, and turned on to ensure a certain level of brightness to illuminate the road during dark times such as nighttime. The "low power" referred to here is, for example, an output of brightness that is at least lower than the brightness (lux) in the illumination on mode.

[0075] When the control unit 15 receives a guidance instruction signal while the illuminating lamp 12 is operating in the illumination mode, the control unit 15 switches the illuminating lamp 12 from the illumination mode to the guidance lighting mode. When the control unit 15 receives a guidance instruction signal while the illuminating lamp 12 is operating in the energy saving mode, the control unit 15 switches the illuminating lamp 12 from the energy saving mode to the guidance lighting mode. In other words, the illuminating lamp 12 is controlled by the control unit 15 to basically operate in the illumination mode or the energy saving mode, and can switch to the guidance lighting mode in response to receiving a guidance instruction signal.

[0076] In this way, when the surrounding illuminance is higher than the reference value, the street light 1 operates in the energy saving mode to reduce power consumption, while the user can be guided in the guidance lighting mode.

[0077] It is not essential that the street light 1 is equipped with the illuminance sensor 16. The street light 1 may use its own clock to determine the current time, for example, by switching from the energy saving mode to the illumination mode at 5:00 PM and from the illumination mode to the energy saving mode at 6:00 AM.

[0078] Furthermore, the guidance lighting mode when the illuminance is higher than the reference value may include an execution period during which the lighting lamp 12 flashes the arrows (Y1, Y2) indicating the specific direction (D1, D2) for guiding the user (evacuee H1). In this case, the specific direction (D1, D2) is displayed by flashing, so that the user's visibility is improved even when the surrounding illuminance is higher than the reference value. The street lamp 1 may flash the arrows (Y1, Y2) regardless of the surrounding illuminance.

[0079] In the following, one of the induction lighting modes that does not include a period during which the lights are turned on to illuminate the surroundings, but only includes an execution period during which the arrows (Y1, Y2) are displayed by flashing, may be referred to as a "bright induction lighting mode."

[0080] When the street light 1 receives the guidance release signal from the management device 30, it stops the receiving unit 14, ends the guidance lighting mode, and switches to the illumination lighting mode (or energy saving mode).

[0081] (3) Management device As described above, the management device 30 (management system) is installed in a management center 3 such as a city hall. The management device 30 may be, for example, a server device, a personal computer, or a tablet terminal. The functions of the management device 30 (management system) may be integrated and installed in one device, or may be distributed and installed in multiple devices.

[0082] The management device 30 is configured to transmit a guidance instruction signal to one or more street lights 1. In addition, the management device 30 is configured to receive a management signal (including identification information of the terminal 2 and street light ID information) from the street light 1 when the street light 1 receives an identification signal from the terminal 2.

[0083] Specifically, the management device 30 includes a first communication unit 31, a second communication unit 32, a third communication unit 33, a control unit 34, a display unit 35, an operation unit 36, and a storage unit 37, as shown in FIG.

[0084] The first communication unit 31 has a communication interface for, for example, wirelessly communicating with the street lights 1A to 1F via a wide area network such as the Internet. The communication between the first communication unit 31 and each street light 1 may be performed in a manner that includes partly wired communication. The first communication unit 31 transmits a guidance instruction signal to the street light 1 and receives a management signal from the street light 1.

[0085] The second communication unit 32 has a communication interface for communicating, for example, wirelessly with each of the shelter devices 40 in the shelters 4A and 4B via a wide area network such as the Internet. The communication between the second communication unit 32 and each of the shelter devices 40 may be performed in a manner that includes partly wired communication. The second communication unit 32 transmits an emergency evacuation signal to the shelter device 40 and receives a signal including shelter information (described later) from the shelter device 40.

[0086] The third communication unit 33 has a communication interface for, for example, wireless communication with a base station 5 of a communication carrier company. The communication between the third communication unit 33 and the base station 5 may be performed in a manner that includes a part of wired communication. The third communication unit 33 transmits an emergency evacuation signal to the base station 5.

[0087] The control unit 34 includes a computer system having one or more processors and a memory. At least some of the functions of the control unit 34 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided through a telecommunication line such as the Internet, or may be recorded in a non-transitory recording medium such as a memory card and provided. The control unit 34 is connected to the first communication unit 31, the second communication unit 32, the third communication unit 33, the display unit 35, the operation unit 36, and the storage unit 37, and controls them.

[0088] In this embodiment, application software relating to disaster countermeasures (hereinafter also referred to as a "disaster countermeasures application") is pre-installed in the management device 30. That is, the control unit 34 has an execution function relating to the disaster countermeasures application.

[0089] The display unit 35 is configured with, for example, a liquid crystal display or an organic EL (Electro-Luminescence) display. The display unit 35 may be configured with a touch panel display. Under the control of the control unit 34, the display unit 35 displays a screen related to the disaster prevention application.

[0090] The operation unit 36 ​​includes, for example, one or more of a mouse, a keyboard, a pointing device, etc. When the display unit 35 is configured with a touch panel display, it also functions as the operation unit 36.

[0091] The storage unit 37 includes an electrically rewritable non-volatile semiconductor memory such as a flash memory. The storage unit 37 stores (contains), for example, resident management information related to residents in the management area including the settlement A1, and the map information described above. The storage unit 37 may be a memory of the control unit 34.

[0092] The resident management information includes the personal ID information (identification information) of the resident (evacuee H1) and the personal information of the resident (address, name, age, sex, date of birth, telephone number, email address, medical information, bank information, etc.). The resident management information and map information can be displayed on the display unit 35.

[0093] For example, when a typhoon is approaching (disaster occurs), a person (hereinafter also referred to as the first manager) who is engaged in management of residents and the like in a management area including settlement A1 at management center 3 such as a city hall operates operation unit 36 ​​to start a disaster prevention app in management device 30. Then, while looking at the screen of the disaster prevention app displayed on display unit 35, the first manager performs an operation input to instruct an emergency evacuation response based on the occurrence of a disaster.

[0094] The control unit 34 transmits an emergency evacuation signal to each evacuation shelter device 40 and the base station 5 through the second communication unit 32 and the third communication unit 33 based on the above operation input.

[0095] Furthermore, when the shelter 4 to which the user is guided is determined, the control unit 34 generates a guidance instruction signal including information indicating the direction of the road markings 7 for each street light 1 based on the location of the shelter 4, and transmits the guidance instruction signal to each street light 1 via the first communication unit 31. Note that the shelter 4 to which the user is guided may change after a while. Each time the shelter 4 to which the user is guided is changed, the control unit 34 transmits a guidance instruction signal to the street light 1 based on the location of the new shelter 4.

[0096] When the control unit 34 receives an instruction to cancel the emergency evacuation response from the first manager via the operation unit 36, the control unit 34 transmits a guidance cancellation signal to each street lamp 1 via the first communication unit 31 to end the guidance lighting mode (i.e., to end the provision of the road markings 7). In addition, in response to the instruction to cancel the emergency evacuation response, the control unit 34 transmits an instruction to cancel the emergency evacuation response to the base station 5 and each evacuation shelter device 40 via the second communication unit 32 and the third communication unit 33.

[0097] [Destination decision function] The shelter 4 to be the guide destination can be manually selected by the first manager via the operation unit 36. When the management device 30 receives an operation input from the first manager via the operation unit 36 ​​to select the shelter 4, the management device 30 can determine the selected shelter 4 as the guide destination.

[0098] Alternatively, the control unit 34 may (automatically) determine the shelter 4 to be the guide destination from among one or more shelters 4 based on the shelter information received from each shelter device 40. That is, the guidance system 100 determines the shelter 4 to be the guide destination based on the shelter information regarding one or more shelters 4 in response to the occurrence of an event requiring evacuation. The function of determining the shelter 4 to be the guide destination is provided, for example, in the management device 30, but may also be provided in the shelter device 40. Then, the management device 30 (control unit 34) transmits a guidance instruction signal to one or more street lights 1 so as to guide the user (evacuee H1) to the shelter 4 determined as the guide destination by the guidance lighting mode.

[0099] The evacuation shelter information is information relating to the evacuation shelter 4. Various types of information that may be included in the evacuation shelter information will be described below.

[0100] The evacuation shelter information may include information regarding the number of evacuees (capacity) that can be accommodated at the evacuation shelter 4. For example, the management device 30 may automatically select a evacuation shelter 4 with a large capacity based on the capacity of the evacuation shelter 4 and in accordance with the scale of the disaster. The memory unit 37 may store information regarding the capacity of each evacuation shelter 4 in advance, and in this case, the evacuation shelter information received from the evacuation shelter device 40 does not need to include information regarding the capacity.

[0101] The evacuation shelter information may include personal ID information of the evacuee H1 who has evacuated to the evacuation shelter 4. The management device 30 can manage which residents are accommodated in the evacuation shelter 4 based on the personal ID information of the evacuee H1 who has evacuated to the evacuation shelter 4. As described below, the personal ID information can be acquired by the evacuation shelter device 40 receiving an identification signal from the terminal 2.

[0102] The evacuation shelter information may include information on the current number of evacuees accommodated (evacuated) at the evacuation shelter 4 (information on the current number of evacuees). The management device 30 may automatically select the evacuation shelter 4 according to the current number of evacuees. The current number of evacuees may be obtained by counting the number of personal ID information of evacuees H1 who have evacuated to the evacuation shelter 4.

[0103] Also, for example, the evacuation shelter 4 may be unavailable due to a power outage or water outage caused by the impact of a disaster, or the evacuation shelter 4 may be unavailable due to reasons such as not being prepared to accept evacuees. The evacuation shelter information may include, for example, information indicating whether the evacuation shelter 4 is available (at the present time). The guidance system 100 (here, the management device 30) may determine the evacuation shelter 4 as the guidance destination based on the information indicating whether the evacuation shelter 4 is available (at the present time). For example, when the guidance system 100 determines based on the evacuation shelter information that the evacuation shelter 4A designated by the first manager in the initial setting is unavailable due to a water outage, it may determine another evacuation shelter 4B as the guidance destination.

[0104] Incidentally, the number of evacuees in the evacuation shelter 4 (for example, the evacuation shelter 4A) being guided increases over time, and the number of evacuees may gradually approach the capacity.

[0105] Therefore, the guidance system 100 (here, the management device 30) of this embodiment has the function of constantly monitoring the number of evacuees at the evacuation shelter 4, and based on the current number of evacuees, deciding (automatically) whether to maintain the evacuation shelter 4 being guided as the guidance destination or to change the guidance destination to another evacuation shelter 4.

[0106] Specifically, after transmitting an emergency evacuation signal to the shelter device 40, the management device 30 (control unit 34) may receive a signal including shelter information from the shelter device 40 via the second communication unit 32 at any time. Based on the number of people information of the shelter 4 being guided to as the shelter information and the capacity of the shelter 4 being guided to, the guidance system 100 determines whether to maintain the shelter 4 being guided to as the guidance destination or to change the guidance destination to another shelter 4. The function of determining whether to maintain the shelter 4 being guided to as the guidance destination or to change the guidance destination to another shelter 4 is provided in, for example, the management device 30, but may also be provided in the shelter device 40.

[0107] In the example of FIG. 1, immediately after the occurrence of a disaster, for example, for residents of village A1, the first manager has designated evacuation shelter 4A as the guide destination. After that, the management device 30 receives evacuation shelter information from the evacuation shelter device 40 of the evacuation shelter 4A as needed, and if the current number of evacuees at the evacuation shelter 4A is equal to or less than the capacity (or equal to or less than a threshold value slightly less than the capacity), the management device 30 maintains the evacuation shelter 4A being guided as the guide destination. However, if the current number of evacuees at the evacuation shelter 4A exceeds the capacity (or the threshold value), the management device 30 changes the evacuation destination to another evacuation shelter 4B and transmits a guidance instruction signal to one or more street lights 1 to guide them to the evacuation shelter 4B.

[0108] In this way, by (automatically) deciding whether to maintain the shelter 4 being guided as the guide destination or to change the guide destination to another shelter 4, a preferred shelter 4 is more likely to be selected as the guide destination in real time, making it possible to guide people (evacuee H1) more efficiently.

[0109] The current number of evacuees accommodated in shelter 4 does not include the number of evacuees H1 currently moving on the roads (R1 to R3). Therefore, if a decision is made based only on the current number of evacuees accommodated in shelter 4 as to whether to maintain shelter 4 as the destination or to change the destination to another shelter 4, the current number of evacuees accommodated in shelter 4 may exceed its capacity after a few tens of minutes.

[0110] Therefore, the guidance system 100 may estimate the (presumed) current number of evacuees in the shelter 4 to which the evacuees are being guided, based on the number of identification information received from one or more street lights 1. The guidance system 100 may determine whether to maintain the shelter 4 to which the evacuees are being guided as the guide destination or to change the guide destination to another shelter 4, based on the estimation result and the capacity of the shelter 4 to which the evacuees are being guided. In this case, both the function of estimating the current number of evacuees and the function of determining whether to maintain the shelter 4 as the guide destination or to change the guide destination to another shelter 4 may be provided in, for example, the management device 30. Alternatively, at least one of these functions may be provided in the shelter device 40.

[0111] In addition, the guidance system 100 may estimate the (assumed) current number of evacuees based on both the number of identification information received from one or more street lights 1 and the current number of evacuees obtained by the evacuation shelter device 40.

[0112] (4) Shelter equipment As described above, each of the one or more (two in FIG. 1 ) shelter devices 40 is installed in a shelter 4 such as a community center. That is, the one or more shelter devices 40 are associated with one or more shelters 4. The shelter device 40 may be, for example, a server device, a personal computer, or a tablet terminal.

[0113] 7, the shelter device 40 (shelter system) includes a communication unit 41, a receiving unit 42, a control unit 43, a display unit 44, an operation unit 45, and a storage unit 46. The functions of the shelter device 40 (shelter system) may be integrated and installed in one device, or may be distributed and installed in multiple devices.

[0114] The communication unit 41 has a communication interface for, for example, wirelessly communicating with the management device 30 via a wide area network such as the Internet. The communication between the communication unit 41 and the management device 30 may be performed in a manner that includes partly wired communication. The communication unit 41 receives an emergency evacuation signal from the management device 30, and transmits a signal including evacuation shelter information to the management device 30.

[0115] The receiving unit 42, like the receiving unit 14 of the street lamp 1, has a communication interface for receiving an identification signal from the terminal 2 through short-range wireless communication with the terminal 2. The receiving unit 42 receives an identification signal including identification information from the terminal 2 that is present within a certain range. The short-range wireless communication method may be, for example, a wireless communication method that complies with standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or low-power wireless that does not require a license (specified low-power wireless).

[0116] The control unit 43 includes a computer system having one or more processors and a memory. At least a part of the functions of the control unit 43 is realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided through a telecommunication line such as the Internet, or may be recorded in a non-transitory recording medium such as a memory card and provided. The control unit 43 is connected to the communication unit 41, the receiving unit 42, the display unit 44, the operation unit 45, and the storage unit 46, and controls them.

[0117] In this embodiment, application software related to disaster shelters (hereinafter also referred to as a "disaster shelter app") is pre-installed in the shelter device 40. That is, the control unit 43 has an execution function related to the disaster shelter app.

[0118] In this embodiment, the control unit 43 does not always activate the receiving unit 42. Only when the communication unit 41 receives an emergency evacuation signal from the management device 30, the control unit 43 activates the receiving unit 42, establishes wireless communication of the receiving unit 42 with the terminal 2 that is present within a certain range, and causes the receiving unit 42 to receive an identification signal.

[0119] The display unit 44 is configured with, for example, a liquid crystal display or an organic EL (Electro-Luminescence) display. The display unit 44 may be configured with a touch panel display. Under the control of the control unit 43, the display unit 44 displays a screen related to the disaster evacuation shelter app.

[0120] The operation unit 45 includes, for example, one or more of a mouse, a keyboard, a pointing device, etc. When the display unit 44 is configured with a touch panel display, it also functions as the operation unit 45.

[0121] The storage unit 46 includes an electrically rewritable non-volatile semiconductor memory such as a flash memory. The storage unit 46 stores, for example, information about the evacuation shelter 4 (such as the capacity of the evacuation shelter 4). The storage unit 46 may be a memory of the control unit 43.

[0122] For example, when the evacuation shelter device 40 of the evacuation shelter 4 receives an emergency evacuation signal from the management device 30 in response to an approaching typhoon (disaster occurrence), it notifies the occurrence of a disaster. This notification is sent by email or the like to a mobile terminal (e.g., a mobile phone such as a smartphone) carried by a person (hereinafter also referred to as the second manager) who manages a facility (evacuation shelter 4) such as a community center. Information regarding the mobile terminal of the second manager (e.g., email address, phone number, etc.) is registered (stored) in advance in the storage unit 46.

[0123] When the second manager is notified of the occurrence of a disaster, he or she prepares to accept evacuees at a facility (shelter 4), such as a community center. The second manager also starts a disaster shelter app on the shelter device 40. While viewing the disaster shelter app screen displayed on the display unit 44, the second manager performs an operation input on the shelter device 40 to transmit a signal including shelter information regarding the shelter 4. As described above, the shelter information may include information that the shelter 4 is available and information on the number of people in the shelter 4. In response to the operation input, the shelter device 40 transmits a signal including the shelter information to the management device 30 via the communication unit 41.

[0124] [Function for managing the number of evacuees] The shelter apparatus 40 of this embodiment has a function of managing information on the current number of evacuees in the shelter 4 in which the shelter apparatus 40 is installed.

[0125] When the control unit 43 of the shelter device 40 corresponding to the shelter 4 being guided receives the identification signal from the terminal 2 at the receiving unit 42, it determines that a user (evacuee) carrying the terminal 2 has evacuated to the shelter 4. The control unit 43 counts the number of people and estimates the current number of evacuees at the shelter 4 being guided from the counting result.

[0126] The control unit 43 periodically (or at any timing) transmits shelter information including headcount information on the (estimated) current number of evacuees to the management device 30. In short, the shelter device 40 corresponding to the shelter 4 being guided among one or more shelter devices 40 acquires headcount information on the current number of evacuees accommodated in the shelter 4 being guided. Then, the shelter device 40 transmits the shelter information including the headcount information to the management device 30.

[0127] The current number of evacuees may be counted directly by the second manager by visual inspection or the like and manually inputted at any time to the evacuation shelter device 40. The management device 30 may transmit evacuation shelter information including the number information on the number of evacuees inputted by the second manager to the management device 30 every time the management device 30 receives an operational input of the current number of evacuees from the second manager via the operation unit 45.

[0128] (5) Telecommunications carrier base stations A base station 5 of a communication carrier company, for example, wirelessly communicates with a management device 30 and a plurality of terminals 2 within a target area (managed region).

[0129] When the base station 5 receives the emergency evacuation signal from the management device 30, it sends a message by area mail to all terminals 2 within the target area instructing them to take emergency evacuation measures, and also replies to the management device 30 that the instructions for emergency evacuation measures have been sent.

[0130] (6) Terminal As described above, the terminal 2 is a mobile terminal carried by the user (evacuee H1), and is a mobile phone (a smartphone, for example).

[0131] The processing unit of the terminal 2 includes a computer system having one or more processors and a memory. At least some of the functions of the processing unit of the terminal 2 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided via a telecommunication line such as the Internet, or may be provided by recording it on a non-transitory recording medium such as a memory card.

[0132] The terminal 2 has a communication interface for communicating with the base station 5. In addition, the terminal 2 has dedicated application software installed therein for short-range wireless communication with the street light 1.

[0133] The terminal 2 stores in its own memory personal ID information for each resident (evacuee H1) that has been assigned to them by the management center 3. The personal ID information is, for example, information consisting only of a number assigned to an individual. Personal information linked to this number (address, name, age, sex, date of birth, telephone number, email address, medical information, bank information, etc.) is managed by the management device 30 as resident management information. Therefore, measures are taken to prevent personal information from being accidentally leaked.

[0134] When the terminal 2 is located within a certain range from the street light 1 and when the street light 1 receives a guidance instruction signal and wireless communication is established between the receiving unit 14 of the street light 1 and the terminal 2, the terminal 2 transmits an identification signal including personal ID information (identification information) to the receiving unit 14.

[0135] In addition, when the terminal 2 is located within a certain range from the shelter device 40 and the shelter device 40 receives an emergency evacuation signal and wireless communication is established between the receiving unit 42 of the shelter device 40 and the terminal 2, the terminal 2 transmits an identification signal including personal ID information (identification information) to the receiving unit 42.

[0136] (7) Guidance system operation [Example 1] A series of flows of the operation example 1 of the guidance system 100 will be described below with reference to Fig. 1 and Fig. 8 (sequence diagram). The sequence diagram of Fig. 8 is merely one example of the operation flow related to the guidance system 100, and the order of the processes may be changed as appropriate, and processes may be added or omitted as appropriate. Below, the operation example 1 of the guidance system 100 will be described using as an example a response when a natural disaster such as a typhoon occurs or when there is a risk of a natural disaster occurring.

[0137] First, the operation of the street lamp 1 (street lamps 1A to 1F) in a normal state will be briefly described.

[0138] The street light 1 determines whether it is in a state where it can receive power from the commercial power source AC1 (see FIG. 5), and if it is in a state where it can receive power from the commercial power source AC1, it operates using power from the commercial power source AC1. On the other hand, if the street light 1 is not in a state where it can receive power from the commercial power source AC1, it operates using power from the battery 19.

[0139] The street light 1 detects the illuminance around the pole 11 (i.e., the brightness of the location where the street light 1 is installed) using the illuminance sensor 16. If the surroundings are dark (if the illuminance is below a reference value), the street light 1 turns on the illuminating light 12 (continuously) (executes the illumination mode). If the surroundings are bright (if the illuminance is higher than a reference value), the street light 1 turns off the illuminating light 12, for example (executes the energy saving mode). Under normal conditions, the street light 1 (street lights 1A to 1F) performs such operations continuously.

[0140] When the above-mentioned natural disaster occurs (or there is a possibility of it occurring), the first manager starts a disaster prevention app on the management device 30 as shown in FIG. 8 (step ST1). Then, the management device 30 transmits an emergency evacuation signal from the second communication unit 32 and the third communication unit 33 to the shelter device 40 and the base station 5 in response to, for example, an operation by the first manager (step ST2). The emergency evacuation signal may be transmitted to each shelter device 40, but in this operation example 1, as an example, it is assumed that the signal is transmitted only to the shelter device 40 of the shelter 4A designated as the guide destination by the first manager in the initial setting.

[0141] Furthermore, the management device 30 transmits a guidance instruction signal from the first communication unit 31 to the street lights 1A to 1F in response to, for example, an operation by the first manager (step ST3). In the example of Fig. 8, for convenience, only one shelter device 40 (for example, the shelter device 40 of the shelter 4A) and only one street light 1 (for example, the street light 1A) are illustrated.

[0142] When the evacuation shelter device 40 of the evacuation shelter 4A receives the emergency evacuation signal through its communication unit 41, it activates the receiving unit 42 (step ST4). In addition, the evacuation shelter device 40 of the evacuation shelter 4A transmits a signal including evacuation shelter information to the management device 30 in response to, for example, an operation by the second manager (step ST5). The evacuation shelter information may include one or more of the following: the current number of people in the evacuation shelter 4A, the personal ID information of the evacuee H1 who has evacuated to the evacuation shelter 4A, the capacity of the evacuation shelter 4A, and information on whether the evacuation shelter 4A is available. The evacuation shelter information including the personal ID information and the number of people information may be transmitted to the management device 30 not only in step ST5 but also from time to time thereafter. The evacuation shelter information may be displayed on the display unit 35 of the management device 30 and the display unit 44 of the evacuation shelter device 40. The first manager and the second manager can respectively check the evacuation shelter information displayed on the display unit 35 and the display unit 44 to grasp the current number of evacuees.

[0143] When each street light 1 receives the guidance instruction signal via its communication unit 13, it activates the receiving unit 14 (step ST6) and operates the illuminating lamp 12 in guidance lighting mode (step ST7). Installation information regarding the installation position and installation orientation of each street light 1 is managed as map information by the management device 30, as described above. Each street light 1 provides road markings 7 that indicate a direction based on map information including the installation information of the street light 1, road position information, and evacuation shelter 4 position information.

[0144] When each street light 1 receives a guidance instruction signal from the management device 30 during a time period when it is dark (for example, at night), it switches from the illumination on mode to the dark induction lighting mode, which is one of the induction lighting modes. As described above, the dark induction lighting mode is a mode that alternates between a first period (illumination on period) and a second period (induction lighting period) (the first period is longer than the second period).

[0145] The lighting lamps 12 are arranged on the top of the support poles 11, and operate in the guidance lighting mode during emergency evacuation, and the lighting and guidance lighting are alternately repeated, so that evacuees H1 can easily understand from a distance that the street lights 1 are guiding them to evacuation. Therefore, the guidance system 100 can call many evacuees H1 to the nearest street light 1 and instruct them to evacuate to an appropriate evacuation shelter 4.

[0146] When each street light 1 receives a guidance instruction signal from the management device 30 during a time period when the surroundings are bright (e.g., daytime), it switches from the energy saving mode to the daytime guidance lighting mode, which is one of the guidance lighting modes. As described above, the daytime guidance lighting mode is a mode that does not include a period during which lighting is turned on to illuminate the surroundings, but only includes an execution period during which the lighting display of the arrows (Y1, Y2) is flashed. In the daytime guidance lighting mode, each street light 1 intermittently lights up the lighting display of the arrows (Y1, Y2). This increases visibility to users even during times when the surroundings are bright (e.g., daytime).

[0147] When the base station 5 receives the emergency evacuation signal, it transmits a message to all terminals 2 in the target area by area mail to instruct them to take emergency evacuation measures (step ST8). The base station 5 also replies to the management device 30 that it has instructed them to take emergency evacuation measures (not shown in FIG. 8). If there is no reply from the base station 5 that it has instructed them to take emergency evacuation measures, the management device 30 transmits the emergency evacuation signal again.

[0148] When each terminal 2 in the target area receives an instruction to respond to emergency evacuation from the base station 5 by area mail, it sounds an alarm from the speaker and displays an instruction message for emergency evacuation on the display (step ST9). The user of the terminal 2 (evacuee H1) sees the instruction message for emergency evacuation on the display and starts evacuation activities to evacuate to the evacuation shelter 4. In addition, by receiving the instruction to respond to emergency evacuation from the base station 5, the terminal 2 starts a signal transmission mode to transmit an identification signal including personal ID information (identification information) stored in the memory of the terminal 2 to a nearby street lamp 1 (step ST10). Note that the transmission distance over which the identification signal can be transmitted from the terminal 2 is preferably less than a dozen meters, for example, less than a few meters, in order to identify the transmission position of the terminal 2 (i.e., the current position of the evacuee H1) in the management device 30.

[0149] Each street light 1 receives, at the receiver 14, an identification signal (step ST11) transmitted from the terminal 2 of the evacuee H1 who has gathered relying on the guidance lighting, and transmits a management signal including the identification information and street light ID information from the communication unit 13 to the management device 30 (step ST12). The management device 30 receives the management signal (identification information) from each street light 1 at the first communication unit 31, and identifies the current location, etc. of the evacuee H1 in the middle of evacuation from the personal ID information contained in the management signal (step ST13), and stores it in the memory unit 37. It is also preferable that the receiving distance of the receiver 14 for the identification signal from the terminal 2 is within a dozen meters or less, for example, within a few meters, in the vicinity of each street light 1 in order to identify the current location of the evacuee H1.

[0150] Thereafter, when the evacuee H1 carrying the terminal 2 arrives at the evacuation shelter 4A following the road markings 7 on the street lamp 1, the terminal 2 transmits an identification signal to the evacuation shelter device 40 of the evacuation shelter 4A (step ST14). The evacuation shelter device 40 receives the identification signal at its receiving unit 42, stores the personal ID information (identification information) included in the identification signal in the storage unit 46, and transmits it from the communication unit 41 to the management device 30 as evacuation shelter information (step ST15). The management device 30 receives the evacuation shelter information, and identifies the name, address, etc. of the evacuee H1 who has completed evacuation from the personal ID information included in the evacuation shelter information (step ST16), and stores it in the storage unit 37.

[0151] The first manager can display the identification information on the evacuee H1 (identified in step ST13) and the evacuee H1 (identified in step ST16) on the display unit 35 and check it at any time. The first manager can easily identify residents whose evacuation is delayed by taking the identification information into consideration. In the management center 3, as shown in FIG. 1, manpower (searchers H2) can be efficiently allocated only to searching for residents whose evacuation is delayed. In addition, the first manager can easily predict how many residents will evacuate to the evacuation shelter 4A in the future, which makes it easier to plan evacuation measures. The identification information may be transmitted to the evacuation shelter device 40.

[0152] [Example 2] Hereinafter, a series of flows of the operation example 2 of the guidance system 100 will be described with reference to Fig. 9 (flowchart). The flow chart in Fig. 9 is merely one example of an operation flow related to the guidance system 100, and the order of processes may be changed as appropriate, and processes may be added or omitted as appropriate.

[0153] In the above-mentioned operation example 1, the number of evacuees in the evacuation shelter 4A being guided increases over time, and the number of evacuees may exceed the capacity. Operation example 2 relates to the operation of the guidance system 100 (particularly the management device 30) executed to prevent the evacuees from exceeding the capacity.

[0154] In the second operational example, the management device 30 monitors the number of evacuees in the shelter 4A being guided from the time when the emergency evacuation signal is transmitted in step ST2 in the first operational example. Specifically, the management device 30 estimates the (presumed) current number of evacuees in the shelter 4A based on the number of pieces of personal ID information (identification information) received by the street light 1 and the number of pieces of personal ID information (identification information) acquired by the shelter device 40. Note that the process of estimating the number of evacuees may be executed by the shelter device 40 instead of the management device 30.

[0155] As shown in Fig. 9, during guidance to the evacuation shelter 4A, the management device 30 receives a management signal (step ST12 in Fig. 8) including personal ID information from each street lamp 1 at any time (step ST21). In addition, during guidance to the evacuation shelter 4A, the management device 30 receives evacuation shelter information (step ST15 in Fig. 8) including personal ID information from the evacuation shelter device 40 of the evacuation shelter 4A at any time (step ST22).

[0156] Then, the management device 30 estimates the current number of evacuees in the evacuation shelter 4A periodically (or at any timing according to the operation of the first manager) based on the information received in steps ST21 and ST22 (step ST23). The management device 30 determines whether the estimated current number of evacuees exceeds the capacity of the evacuation shelter 4A (whether the capacity is exceeded) (step ST24). Note that the process of determining whether the capacity is exceeded may be executed by the evacuation shelter device 40 instead of the management device 30.

[0157] If the estimated current number of evacuees is equal to or less than the capacity, that is, if the capacity is not exceeded (ST24: No), the management device 30 decides to maintain the current guidance destination (shelter 4A) (step ST25). Then, the process proceeds to step ST28 (described later).

[0158] On the other hand, if the estimated current number of evacuees exceeds the capacity, that is, the capacity is exceeded (ST24: Yes), the management device 30 decides to change the current guidance destination (shelter 4A) to another shelter (for example, shelter 4B) (step ST26). Then, the management device 30 generates a guidance instruction signal including information indicating the direction of the road marking 7 for each street light 1 based on the location of the shelter 4B so as to guide the evacuees to the shelter 4B, and transmits the guidance instruction signal to each street light 1 (step ST27). As a result, the street light 1A provides road markings 7 indicating the north direction, the street lights 1B, 1E, and 1F provide road markings 7 indicating the east direction, and the street lights 1C and 1D provide road markings 7 indicating the west direction, respectively. Thereafter, the evacuee H1 evacuates to the shelter 4B while visually checking the changed road markings 7 of the street light 1.

[0159] In addition, in response to the decision to change the guidance destination, the management device 30 transmits a signal to the shelter device 40 of the shelter 4A to the effect that the shelter 4A has been removed as a guidance destination (due to exceeding capacity), and in response to receiving the signal, the shelter device 40 of the shelter 4A shuts down the receiving unit 42 that was running.

[0160] Furthermore, in response to the decision to change the guide destination, the management device 30 transmits to the shelter device 40 of the shelter 4B a notification that the shelter 4B has become the guide destination, i.e., an emergency evacuation signal. In response to receiving the emergency evacuation signal, the shelter device 40 of the shelter 4B starts the receiving unit 42. Thereafter, the management device 30 receives a signal including the shelter information from the shelter device 40 of the shelter 4B, monitors the number of evacuees being guided to the shelter 4B, and if the shelter 4B also exceeds its capacity, the management device 30 can change the guide destination to yet another shelter.

[0161] After that, when the typhoon passes (or weakens) and it is decided to cancel the emergency evacuation response in the target area (managed area), the first manager inputs an instruction to cancel the emergency evacuation response via the operation unit 36. When the management device 30 receives an instruction to cancel the emergency evacuation response from the first manager via the operation unit 36 ​​(step ST28: Yes), it transmits a guidance cancellation signal to each street light 1 to end the guidance lighting mode (step ST29). The management device 30 also transmits an instruction to cancel the emergency evacuation response to the base station 5 and each evacuation shelter device 40.

[0162] As a result, in response to receiving the guidance cancellation signal, each street light 1 stops the operating receiver 14 and switches its operation mode to illumination mode if the surroundings are dark, or to energy saving mode if the surroundings are bright.

[0163] When the evacuation shelter device 40 receives an instruction to cancel the emergency evacuation response from the management device 30, it stops the receiving unit 42 that is running.

[0164] When the base station 5 receives the instruction to cancel the emergency evacuation response from the management device 30, it transmits a message to all terminals 2 in the target area by area mail to the effect that the emergency evacuation response has been canceled. The base station 5 also replies to the management device 30 to the effect that the emergency evacuation response has been canceled.

[0165] When the terminal 2 receives an area mail from the base station 5 informing it that the emergency evacuation response has been lifted, it ends the signal transmission mode in which it transmits to the street light 1 an identification signal including personal ID information (identification information).

[0166] With the above, the guidance system 100 ends a series of processes related to emergency evacuation response.

[0167] In this way, the street light 1 and the guidance system 100 can obtain identification information to be transmitted to the management device 30 from the terminal 2 of the user (evacuee H1) while guiding the user of the terminal 2 in the guidance lighting mode. As a result, the street light 1 and the guidance system 100 have the advantage of making it easier to realize efficient guidance and management of people.

[0168] In the induction lighting mode, the illumination lamp 12 lights up and displays an arrow (Y1, Y2) indicating a specific direction (D1, D2) for guiding the user, so that it is easy to guide the user in the specific direction (D1, D2) by utilizing the illumination of the illumination lamp 12. In particular, the illumination lighting for illuminating the periphery of the support pole 11 and the induction lighting for guiding the user can be satisfactorily achieved by the plurality of illumination elements 122 arranged in a plane.

[0169] In addition, the street lamp 1 and the guidance system 100 can freely change the guidance direction depending on the location of the evacuation shelter. Also, the lighting operation can be changed depending on whether the surroundings are dark or bright. Furthermore, the personal ID information of the evacuee H1 can be easily acquired (received). Therefore, the efficiency of evacuation guidance can be improved.

[0170] The street lamp 1 does not receive personal ID information (identification information) by the receiving unit 14 unless a guidance instruction signal is received, so that high reliability is obtained for privacy. Similarly, the evacuation shelter device 40 does not receive personal ID information (identification information) by the receiving unit 42 unless an emergency evacuation response instruction is received, so that high reliability is obtained for privacy.

[0171] (8) Variation 1 Hereinafter, as a modification of the above embodiment, a street lamp 1 and a guide system 100A according to a modification 1 will be described with reference to Figs.

[0172] Regarding the street light 1 and the guidance system 100A according to the following modified example 1, the configurations substantially common to the above embodiment are denoted by the same reference numerals, and the description thereof may be omitted as appropriate. In particular, since the street light 1 according to the modified example 1 has substantially the same configuration as the street light 1 of the above embodiment, the description of the configuration thereof will be omitted.

[0173] The guidance system 100A of the first modification is applied to guide a user in, for example, a facility 6 and its surroundings. FIG. 10 is a conceptual diagram overlooking the facility 6 and its surroundings. Here, the facility 6 is assumed to be an event venue 60 where an event is held (for example, a baseball field, soccer field, or live music venue) and to have multiple entrances and exits (gates 61-64). However, the facility 6 is not limited to the event venue 60, and may be, for example, a commercial facility, a school, a hospital, a station, an airport, or an apartment building.

[0174] In the first modification, the user is a person who uses the facility 6. Here, since the facility 6 is an event venue 60, it is assumed that the user is a participant H3 who participates in the event.

[0175] The guidance system 100A of the first modification includes one or more street lights 1 (eight street lights 1G to 1N in FIG. 10) and a management device 8 (see FIG. 11) that transmits a guidance instruction signal to each street light 1. The management device 8 may be installed, for example, in a facility 6 (event venue 60). Of the eight street lights 1, four street lights 1G to 1J are installed around the entrances and exits of the facility 6 (gates 61 to 64).

[0176] The remaining four street lamps 1K to 1N are installed at positions farther away from the event venue 60. The installation positions of the street lamps 1 will be described in more detail below.

[0177] As shown in FIG. 10, the event venue 60 is surrounded by, for example, a substantially circular fence W1 (or wall). Around the event venue 60 is a donut-shaped road R10 (hereinafter also referred to as the "first area AR1"). Four of the eight street lights 1 (street lights 1G-1J) are installed on the road R10 (first area AR1). Participant H3 passes through the road R10, enters from one of the entrances (61B, 62B, 63B, 64B) of the gates (61-64), exits from one of the exits (61A, 62A, 63A, 64A) of the gates (61-64), and returns home via the road R10.

[0178] In Figure 10, if the upward direction is the "north direction," an entrance and exit are paired at each of the east-west-north-south gate positions of the fence W1 of the event venue 60, and one street light 1 is installed next to each exit.

[0179] Specifically, the "South Gate 61" includes an entrance 61B and an exit 61A for entering / exiting the event venue 60, and a street light 1G is installed next to the exit 61A facing road R10. The "East Gate 62" includes an entrance 62B and an exit 62A, and a street light 1H is installed next to the exit 62A facing road R10. The "North Gate 63" includes an entrance 63B and an exit 63A, and a street light 1I is installed next to the exit 63A facing road R10. The "West Gate 64" includes an entrance 64B and an exit 64A, and a street light 1J is installed next to the exit 64A facing road R10.

[0180] In short, the guidance system 100A of the first modification includes a plurality of street lights 1. The plurality of street lights 1 include one or more first street lights 101 (four in this example) installed in a first area AR1 around a plurality of entrances (gates 61-64) of the event venue 60. In FIG. 10, each of the four street lights 1G-1J corresponds to the first street light 101.

[0181] Four roads R11 to R14 (hereinafter also referred to as "second area AR2") radiate outward from the doughnut-shaped road R10 (first area AR1). The four roads R11 to R14 may be, for example, roads leading from the event venue 60 to the nearest station, parking lot, restaurant district, etc.

[0182] Street lights 1K to 1N are installed on these four roads R11 to R14, respectively. Specifically, in the second area AR2, a street light 1K is installed on the road R11 extending to the southwest, a street light 1L is installed on the road R12 extending to the southeast, a street light 1M is installed on the road R13 extending to the northeast, and a street light 1N is installed on the road R14 extending to the northwest.

[0183] In other words, the multiple street lamps 1 further include, in addition to the one or more first street lamps 101, one or more (four in this case) second street lamps 102 installed in a second area AR2 that is further away from the event venue 60 than the first area AR1. In FIG. 10, each of the four street lamps 1K to 1N corresponds to the second street lamp 102.

[0184] After the event ends at the event venue 60, the participants H3 will use the roads R10 to R14 as appropriate to head to their destinations, such as a station, a parking lot, or a restaurant district. In a relatively large-scale event, when a large number of participants H3 leave the event venue 60 all at once after the event ends, it may be preferable in terms of safety measures to provide dispersion guidance to the roads R10 to R14 to relieve congestion as much as possible. Alternatively, when an emergency evacuation occurs during the event and participants H3 and the like evacuate from the event venue 60, it may be preferable in terms of safety measures to provide dispersion guidance to the roads R10 to R14. Also, when the participant H3 is about to enter the event venue 60, he or she will use the roads R10 to R14 as appropriate, so it may be preferable in terms of safety measures to provide dispersion guidance to the roads R10 to R14.

[0185] Therefore, in variant example 1, the management device 8 transmits a guidance instruction signal to each street light 1 so as to guide the user (participant H3) in entering / exiting the facility 6 in the guidance lighting mode within a specified period of time, and manages the identification information received from each street light 1.

[0186] Here, it is assumed that the guidance system 100A guides the user (participant H3) to exit (leave) from the facility 6 in the guidance lighting mode within a predetermined period of time. However, the guidance system 100A may guide the user (participant H3) to enter (enter) the facility 6 in the guidance lighting mode within the predetermined period of time instead of (or in addition to) exiting (leaving). The details of the "predetermined period" will be described later, but it is assumed to be, for example, five hours.

[0187] The management device 8 transmits a guidance instruction signal to one or more (four in this case) first street lights 101 so as to guide the user (participant H3) to enter / exit (exit in this case) the event venue 60 in the guidance lighting mode within a predetermined period of time. Then, the management device 8 manages the identification information received from one or more (four in this case) first street lights 101.

[0188] Furthermore, the management device 8 transmits a guidance instruction signal to one or more (four in this case) second street lights 102 so as to guide the user (participant H3) to enter / exit (exit in this case) the event venue 60 in the guidance lighting mode within a predetermined period of time. Then, the management device 8 manages the identification information received from one or more (four in this case) second street lights 102.

[0189] 11, the management device 8 (management system) includes a control unit 80, a communication unit 81, a receiving unit 82, a microphone 83, a speaker 84, a display unit 85, an operation unit 86, and a storage unit 87. The management device 8 may be, for example, a server device, a personal computer, or a tablet terminal. The functions of the management device 8 (management system) may be integrated and installed in one device, or may be distributed and installed in multiple devices.

[0190] The communication unit 81 has a communication interface for communicating, for example, wirelessly with the street lights 1A to 1F via a wide area network such as the Internet. The communication between the communication unit 81 and each street light 1 may be performed in a manner that includes partly wired communication. The communication unit 81 transmits a guidance instruction signal to the street light 1 and receives a management signal from the street light 1.

[0191] The receiving unit 82 includes four receiving terminals T1 to T4 (see FIG. 10) having a communication interface for receiving an identification signal from the terminal 2 through short-distance wireless communication with the terminal 2. Each of the receiving terminals T1 to T4 receives an identification signal transmitted from the terminal 2 when a user (participant H3) of the terminal 2 present within a certain range performs an operation input related to admission reception on the terminal 2. The short-distance wireless communication method may be, for example, a wireless communication method conforming to standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or low-power wireless that does not require a license (specified low-power wireless).

[0192] The control unit 80 includes a computer system having one or more processors and a memory. At least some of the functions of the control unit 80 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided through a telecommunication line such as the Internet, or may be recorded in a non-transitory recording medium such as a memory card and provided. The control unit 80 is connected to a communication unit 81, a receiving unit 82, a microphone 83, a speaker 84, a display unit 85, an operation unit 86, and a storage unit 87, and controls them.

[0193] In this embodiment, application software relating to safety measures (hereinafter also referred to as a "safety measures app") is pre-installed in the management device 8. That is, the control unit 80 has an execution function relating to the safety measures app.

[0194] The display unit 85 is configured with, for example, a liquid crystal display or an organic EL (Electro-Luminescence) display. The display unit 85 may be configured with a touch panel display. Under the control of the control unit 80, the display unit 85 displays a screen related to the safety measure app.

[0195] The operation unit 86 includes, for example, one or more of a mouse, a keyboard, a pointing device, etc. When the display unit 85 is configured with a touch panel display, it also functions as the operation unit 86.

[0196] The storage unit 87 includes an electrically rewritable non-volatile semiconductor memory such as a flash memory. The storage unit 87 stores (stores), for example, map information. The map information includes installation information of street lights 1 in the vicinity of the facility 6 and position information of roads (R10 to R14). The map information can be displayed on the display unit 85. The storage unit 87 may be a memory of the control unit 80.

[0197] Furthermore, the memory unit 87 may store participant management information regarding participant H3. The participant management information includes the personal ID information (identification information) of participant H3 and personal information of the participant H3. Unlike the above embodiment, the personal information handled in the first modification may include only information such as an email address, from the viewpoint of privacy. The participant management information may be displayed on the display unit 85. There are no particular limitations on the timing of issuing the personal ID information of participant H3 and the timing of acquiring personal information such as an email address.

[0198] The personal ID information is, for example, information consisting only of a number assigned to an individual. The personal ID information may be issued, for example, when participant H3 purchases an event ticket online using terminal 2. Personal information such as an email address may be input by participant H3 at the time of purchase, and may be stored in the memory and storage unit 87 of terminal 2 as participant management information together with the issued personal ID information.

[0199] Alternatively, the personal ID information may be issued at the time of admission reception to the facility 6. Personal information such as an email address may be input by the participant H3 at the time of admission reception and stored in the memory of the terminal 2 and the storage unit 87 together with the issued personal ID information as participant management information.

[0200] In the first modification, the management device 8 controls the switching of each street light 1 from the illumination lighting mode (or the energy saving mode) to the guidance lighting mode (or vice versa). The communication unit 81 transmits guidance instruction signals to the communication units 13 (see FIG. 5) of the street lights 1G to 1N. The communication unit 81 also receives management signals (including identification information and street light ID information) from the communication units 13 of the street lights 1G to 1N.

[0201] In addition, even in the first modification, each street light 1 performs normal lighting operation until it receives a guidance instruction signal. That is, each street light 1 operates in lighting mode when the surroundings are dark, and in energy saving mode when the surroundings are bright.

[0202] [Example of guidance system operation] A series of flows of an operation example of the guide system 100A will be described below with reference to Fig. 10, Fig. 12 (sequence diagram), and Fig. 13 (sequence diagram). The sequence diagrams of Fig. 12 and Fig. 13 are merely examples of the operation flow related to the guide system 100A, and the order of the processes may be changed as appropriate, and processes may be added or omitted as appropriate. Below, an operation example of the guide system 100A will be described from the situation before entry into the event venue 60 begins.

[0203] Hereinafter, a person who takes safety measures for the facility 6 using the management device 8 will be referred to as a "measure taker." The measure taker may be a person involved in the event organizer, a manager of the facility 6, a security guard, or the like.

[0204] 12 and 13, for convenience, only the receiving terminal T1 of the receiving terminals T1 to T4 is illustrated separately from the management device 8. Also, for convenience, only the street light 1G of the street lights 1G to 1N is illustrated in Figs. 12 and 13.

[0205] First, a description will be given with reference to Fig. 12. For example, before entry begins (before the gate opens), the countermeasure person operates the operation unit 86 to start up the safety countermeasure application in the management device 8 (step ST31). When the control unit 80 receives an operation input for starting up the receiving terminals T1 to T4 (receiving unit 82), it transmits a start-up instruction signal to the receiving terminals T1 to T4 (step ST32).

[0206] The four receiving terminals T1 to T4 are respectively placed at the four entrances (61B to 64B) of the event venue 60, and upon receiving the start-up instruction signal, they begin accepting the personal ID information of participant H3 wishing to enter through terminal 2 (entrance acceptance: step ST33).

[0207] The terminal 2 is a mobile terminal carried by the user (participant H3), such as a mobile phone (one example is a smartphone). The terminal 2 has dedicated application software installed therein for short-distance wireless communication with the receiver 82 and the receiver 14 of the street lamp 1.

[0208] When the time comes for each gate (61 to 64) to open, and participant H3 carrying terminal 2 approaches within a certain range of receiving terminal T1 at south gate 61, for example, wireless communication is established between receiving terminal T1 and terminal 2, and admission acceptance processing is performed for that participant H3.

[0209] In the admission reception process, the receiving terminal T1 transmits a permission request signal to the terminal 2 (step ST34). Specifically, the receiving terminal T1 requests permission from the participant H3 to use the personal ID information stored in the memory of the terminal 2. That is, as described above, the receiving terminal T1 requests the terminal 2 to transmit the personal ID information (identification information) issued, for example, when purchasing a ticket and stored in the memory of the terminal 2.

[0210] In response to receiving the permission request signal, the terminal 2 displays an icon corresponding to the transmission of personal ID information on the screen of the terminal 2. When the participant H3 enters the entrance 61B, the participant H3 performs an operation to permit the transmission of personal ID information by tapping on the icon or the like (step ST35). As a result, the terminal 2 starts a signal transmission mode for transmitting an identification signal (step ST36), and transmits the identification signal including personal ID information (identification information) to the receiving terminal T1 (step ST37). The terminal 2 also starts counting the above-mentioned predetermined period (for example, 5 hours).

[0211] The personal ID information of the attendee (participant H3) received by the receiving terminal T1 at the time of entry is stored (registered) in the memory unit 87 (step ST38). The management device 30 may check whether the personal ID information received by the receiving terminal T1 corresponds to the personal ID information and personal information (such as an email address) in the memory unit 87. If the personal information of participant H3 is not in the memory unit 87, the management device 8 may request further personal information and associate the personal information input by participant H3 with the personal ID information and store them in the memory unit 87. Input of personal information is optional, and the management device 8 may allow personal information not to be input.

[0212] On the other hand, if the personal ID information is not stored in the memory of terminal 2, it may be issued during this entrance reception process, in which case the management device 8 transmits the issued personal ID information from the receiving unit 82 to terminal 2 and stores it in the memory of terminal 2.

[0213] In short, if terminal 2 possesses personal ID information in advance, it transmits it to management device 8 and accepts admission, and if terminal 2 does not possess personal ID information, management device 8 issues it and accepts admission.

[0214] Thereafter, the terminal 2 may automatically transmit the personal ID information to nearby street lights 1 until the above-mentioned predetermined period has elapsed. The participant H3 is notified on the terminal 2 that the above-mentioned permission operation will result in future transmission of personal ID information. When the above-mentioned predetermined period has elapsed, the automatic transmission of personal ID information from the terminal 2 is stopped. The above-mentioned predetermined period is not limited to 5 hours, but is preferably less than 24 hours. The above-mentioned predetermined period may be changed as appropriate depending on, for example, the time from the opening to the closing of the event venue 60.

[0215] Thereafter, when the countermeasure person has restricted (ended) entry to the event venue 60, he / she operates the operation unit 86 to perform an operation input for stopping the receiving terminals T1 to T4. Upon receiving this operation input, the control unit 80 transmits a stop instruction signal to the receiving terminals T1 to T4 (step ST39). As a result, the receiving terminals T1 to T4 stop accepting the personal ID information (step ST40).

[0216] Next, an explanation will be given with reference to Fig. 13. When the event ends, participant H3 leaves from one of the four exits (61A to 64A), passes through road R10, and freely selects one of roads R11 to R14 to move to his or her next destination. Here, as described above, when a (particularly large-scale) event ends and participant H3 leaves the event venue 60, or when an emergency evacuation occurs during the event, it may be preferable from a safety perspective to guide participants to disperse onto roads R10 to R14.

[0217] Therefore, when the end of the event approaches (or when an emergency evacuation situation occurs), the person in charge of the countermeasure operates the operation unit 86 while watching the screen of the safety countermeasure app displayed on the display unit 85, and performs an operation input to instruct a guidance response (step ST41). As a result, the management device 8 transmits a guidance instruction signal to the street lights 1G to 1N (step ST42).

[0218] Each street light 1 starts up the receiver 14 in response to receiving the guidance instruction signal (step ST43), and becomes capable of receiving an identification signal including personal ID information (identification information) from a nearby terminal 2. Also, each street light 1 starts a guidance lighting mode in response to receiving the guidance instruction signal, and provides the road markings 7 (step ST44).

[0219] After instructing streetlights 1G to 1N to take guiding measures, the countermeasure person uses microphone 83 and speaker 84 to make an announcement to participant H3 in event venue 60, for example, "After leaving the exit, please move in the direction indicated by the arrow on the streetlight."

[0220] In the first modification, the direction of the road markings 7 indicated by the street lamps 1G to 1N is a direction set in advance by a countermeasure person, and the setting information is stored in the storage unit 87 of the management device 8.

[0221] In FIG. 10, streetlights 1G-1J near exits 61A-64A present road markings 7 (arrow indications) that point in a clockwise direction overall, guiding participant H3 in one direction (e.g., clockwise: see the four arrows Q1).

[0222] For example, when participant H3 leaves through exit 61A, a street lamp 1G near exit 61A receives an identification signal (personal ID information) from terminal 2 at its receiving unit 14 (see FIG. 5) and transmits a management signal including the personal ID information of the leaving person to management device 8. Management device 8 stores (registers) the received personal ID information of the leaving person in storage unit 87 (step ST47).

[0223] The management device 8 also performs an exit confirmation process to confirm whether or not the visitor has exited by checking the personal ID information of the exiting person against the personal ID information of the visitor (step ST48). The result of the exit confirmation can be displayed on the display unit 85.

[0224] The person in charge of countermeasures can easily grasp those who have left the event venue 60 and those who have not yet left through the results of the exit confirmation displayed on the display unit 85.

[0225] Participant H3, who has moved clockwise, can then be guided to roads R11 to R14 by the road markings 7 (arrow indications) of street lamps 1K to 1N. As a result, congestion and confusion can be easily avoided.

[0226] After confirming the last person to leave, the countermeasure person inputs a guidance cancellation command through the operation unit 86. When the management device 8 receives the guidance cancellation command (step ST49), it transmits a guidance cancellation signal from the communication unit 81 to each street light 1 to end the guidance lighting mode (i.e., to end the provision of the road markings 7) (step ST50). As a result, in response to receiving the guidance cancellation signal, each street light 1 stops the active receiving unit 14 (step ST51), switches the operation mode to the illumination mode if the surroundings are dark, or to the energy saving mode if the surroundings are bright, and ends the guidance lighting mode (step ST52).

[0227] When the above-mentioned predetermined period (for example, 5 hours) has elapsed, the terminal 2 stops the signal transmission mode in which the terminal 2 transmits the identification signal to the street light 1 (step ST53).

[0228] In this way, the street light 1 and guidance system 100A of the first modification can also guide the user (participant H3) of the terminal 2 in the guidance lighting mode, while obtaining identification information to be transmitted to the management device 8 from the terminal 2 of the user. As a result, the street light 1 and guidance system 100A of the first modification have the advantage of making it easier to realize efficient guidance and management of people.

[0229] Furthermore, if the street lamp 1 is applied to the event venue 60, participants H3 of the event venue 60 can be guided to move around in a dispersed manner, improving the safety of their movements. Also, it becomes easier for countermeasure personnel to grasp information about people staying at the event venue 60. As a result, this is an effective safety measure.

[0230] In particular, compared to the case where security guards carry signs to streetlights each time to control people flow, the streetlight 1 and the guidance system 100A make it easier to reduce such manpower and quickly alleviate congestion.

[0231] In addition, in the guide system 100A, the participant H3 himself performs an operation to permit the transmission of his / her personal ID information when entering the event venue 60, and the personal ID information is acquired (received) based on that operation. This prevents the personal ID information from being leaked in a manner unintended by the participant H3. Furthermore, when the above-mentioned predetermined period has elapsed, the transmission of the personal ID information is stopped, thereby reducing the trouble and anxiety of the participant H3.

[0232] The position and number of the street lights 1 and the direction of the road markings 7 (arrow markings) of each street light 1 may be appropriately changed depending on the size of the event venue 60 and the surrounding roads. For example, in addition to (or instead of) the street lights 1G to 1J, street lights 1 may also be installed near each entrance (61B to 64B) to provide guidance when entering.

[0233] Furthermore, the control unit 80 may measure the concentration (congestion) of people around each street light 1 or on the road on which the street light 1 is installed, for each street light 1, from the number of pieces of personal ID information received from that street light 1. The control unit 80 may determine whether people are concentrated on the corresponding road based on the measured congestion degree. For example, the control unit 80 calculates the congestion degree based on the number of pieces of personal ID information received from a certain street light 1 within a certain period of time (for example, several minutes). If the congestion degree is equal to or greater than a reference value, the control unit 80 may determine that the road on which the street light 1 is installed is congested.

[0234] The reference value may be a value based on a number determined in advance according to the scale of the event venue 60 or the road, or a value based on a representative value (e.g., an average number) of the number of pieces of personal ID information received at a plurality of street lamps 1 within the same fixed period of time. The degree of congestion of each street lamp 1 and the judgment result may be displayed in real time on the display unit 85.

[0235] For example, when people are concentrated on road R14, the management device 8 transmits a guidance instruction signal to the street light 1N in response to a command from the countermeasure person via the operation unit 86 to change the road marking 7 (arrow display) of the street light 1N to point toward road R13, i.e., to face "east." As a result, the flow of people can be appropriately changed, and congestion can be alleviated.

[0236] (9) Other modifications Other modified examples are listed below. The other modified examples described below can be applied in appropriate combination with the above embodiment or the above modified example 1.

[0237] Functions similar to those of the guidance system 100 according to the above embodiment and the guidance system 100A according to the above modification 1 may be embodied as a guidance method, a computer program, or a non-transitory recording medium having a computer program recorded thereon.

[0238] Each of the guidance systems 100 and 100A in the present disclosure includes a computer system. The computer system is mainly composed of a processor and a memory as hardware. The processor executes a program recorded in the memory of the computer system to realize the functions of each of the guidance systems 100 and 100A in the present disclosure. The program may be pre-recorded in the memory of the computer system, provided through an electric communication line, or provided by recording it in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). The integrated circuits such as IC or LSI referred to here are called by different names depending on the degree of integration, and include integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Furthermore, a field-programmable gate array (FPGA) that is programmed after the manufacture of the LSI, or a logic device that can reconfigure the connection relationship inside the LSI or reconfigure the circuit partition inside the LSI, can also be adopted as a processor. The electronic circuits may be integrated in one chip or distributed among multiple chips. The chips may be integrated in one device or distributed among multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Thus, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0239] Furthermore, it is not essential that the multiple functions of each of the guidance systems 100 and 100A are integrated into one housing. For example, the components of each of the guidance systems 100 and 100A may be distributed across multiple housings.

[0240] Conversely, multiple functions in each of the guidance systems 100 and 100A may be integrated in one housing. Furthermore, at least some of the functions of each of the guidance systems 100 and 100A, for example, some of the functions of the guidance system 100, may be realized by the cloud (cloud computing) or the like.

[0241] The street light 1 may further include a speaker. In addition to providing the road markings 7, the street light 1 may output a synthesized voice message such as "Please follow the road markings" from the speaker in the guidance lighting mode.

[0242] The display form of the road marking 7 may be characters instead of arrows. For example, the road marking 7 may be a single character indicating either "east-west-north-south" or "up-down-left-right."

[0243] Furthermore, the speaker 84 (see FIG. 11) in the first modification may be attached to each street lamp 1, and may output the announcement (real voice) from the countermeasure person described above.

[0244] In the above embodiment, the guidance system 100 guides the user to one destination (the evacuation shelter 4A) via the street lights 1A-1F. However, the guidance system 100 may guide the user to two or more evacuation shelters 4 (e.g., evacuation shelters 4A and 4B) via the street lights 1A-1F (simultaneously). For example, the road markings 7 may be provided so that the street lights 1A-1D guide the user to the evacuation shelter 4A, and the street lights 1E and 1F guide the user to the evacuation shelter 4B.

[0245] (summary) The above-described embodiments and the like disclose the following aspects.
