Description

  The present invention relates to street lamps.

  Street lamps have been used for a long time. A street lamp is an illuminating device and includes light emitting means such as a fluorescent lamp and an LED. Even at night, a passer-by can use the light emitted from the light emitting means of the street light to illuminate the road as illumination light.

By the way, especially in Japan, the awareness of disaster prevention has increased greatly since the occurrence of the Tohoku-Pacific Ocean Earthquake.
The inventor of the present application can be a great help for disaster victims if a street light that functions only as a lighting device during normal times can be used for an application other than the lighting device in an emergency after a disaster such as an earthquake or tsunami. I thought.
Since street lamps function as lighting devices during normal times, even if there are many street lamps in the streets, there is no hindrance during normal times. In addition, the street light is provided with the light emitting means as described above, but the light emitted from it is not only a illuminating light but also a sense of security for disaster victims, especially at night. To put it exaggeratedly, it is a foundation for the heart. Therefore, as long as the light emitting means is effective, it can be expected that the victims will gather near the street lamps, especially at night, in a state before the evacuation center immediately after the disaster has started to fully function. At that time, if the street light has a function other than the lighting device, it can be a great help for the victims.
However, few proposals have been made so far for providing street lamps with functions other than lighting devices.

  It is an object of the present invention to propose a street light that has a function other than emitting light and can be helpful to a disaster victim.

In order to solve this problem, the present inventor proposes the invention described below.
The present invention is a street lamp that includes a light emitting means that emits light and a main body that supports the light emitting means at a required height, and a large number of them are used as a set.
The main body of the street light is provided with communication means, and the communication means can perform ad hoc wireless LAN communication with communication means included in at least one of the other street lights. In addition, it is possible to perform wireless LAN communication with a portable terminal possessed by a disaster victim.
Information that the victims demand most, especially in the early days of a disaster, is information. It is best if you can communicate using the Internet, but you can't go beyond that if you can at least know the safety of neighbors. As described above, the victims are more likely to gather on the streetlights for peace of mind, especially at night, when the evacuation center immediately after the disaster has not yet started to function sufficiently. Therefore, if the streetlight is provided with the communication function as described above, an effect of giving relief to the disaster victim can be naturally obtained.
In the present invention, this is made possible by communication means provided in the street lamp. This street light is used as a set of a large number (for example, at least 20) of street lights, each of which is provided with a communication means. The communication means provided in the street light can perform wireless LAN communication (for example, communication by Wi-Fi) with a portable terminal owned by the disaster victim. Since mobile terminals are smartphones, tablets, and the like, and most of them can perform wireless LAN communication at present, it is normally possible for mobile terminals and street lamps to communicate. Due to the functions of the mobile terminal and street light, the victim can communicate with the nearest emergency light using his mobile terminal. On the other hand, the communication means provided in the street light can perform ad hoc wireless LAN communication with the communication means provided in at least one of the other street lights. As a result, a disaster victim having a portable terminal can communicate with a communication network formed by a number of street lamps that perform ad hoc wireless LAN communication. It is assumed that there is a virtual bulletin board on the communication network that can post the safety of the victim, for example, managed by the government. The victim can write his / her safety on the bulletin board, or can confirm the safety of his / her family, for example.
In addition, each street light performs the ad hoc wireless LAN communication as described above, so that a victim who communicates with the street light that is his / her mobile terminal can directly communicate with the street light or at least one other It is also possible to form a state in which other street lamps that can communicate with each other through street lamps and other victims that communicate with each other through their mobile terminals can communicate with each other. Thereby, a state where each victim can directly communicate with each other can be formed.

In order to obtain the same effect as the street lamp described above, the inventor of the present application provides a number of street lamps including a light emitting means for emitting light and a main body portion that supports the light emitting means at a required height. A set of street lamps is also proposed as one aspect of the present invention.
The main body of each of the street lamps in the street lamp set is provided with a communication unit, and the communication unit performs ad hoc wireless LAN communication with a communication unit included in another street lamp. In addition, it is possible to perform wireless LAN communication with portable terminals held by disaster victims.

The reason why the communication means included in the street lamp according to the present invention is able to perform ad-hoc wireless LAN communication with the communication means included in other street lamps is the strength of communication based on its flexibility ("stiffness" This means that it is possible to maintain the above-mentioned communication network formed by the entire street lamp with high possibility.). Ad-hoc wireless LAN communication is a communication format that does not use a dedicated base station, and each terminal device can temporarily communicate with each other by using the relay function of each terminal device that participates in the communication network. Is a technology for creating a simple terminal device group (communication network). Such a communication network is called an ad hoc network or the like, but in an ad hoc network, by using a technology of “multi-hop communication” that connects a large number of terminal devices without intervening base stations, even without a base station, It has the advantage that the communication area can be expanded while relaying other terminals.
In that sense, it is ideal that the portable terminal of the disaster victim can perform ad hoc wireless LAN communication with the communication device of the street light. By doing so, each victim will be able to use other disaster victims, distant people who are not affected by the disaster, and portable terminals held by each other. ) Will be able to communicate.
In any case, the communication means included in the street lamp in the present invention can be used for ad-hoc wireless LAN communication with the communication means included in other street lamps. Even if wireless LAN communication can no longer be performed, at least a part of the above-described communication network can be utilized if communication means included in some street lamps is effective.
In order to make the communication network more robust, in the case of the street light set of the present invention, at least one of the communication means of the street lights is a plurality of the other street lights. It is preferable that an ad hoc wireless LAN communication can be performed with the communication means included in the network. In this case, for example, even if the communication means of one street lamp stops functioning, wireless LAN communication between the communication means of the street lamps around it can be maintained. It is possible to maintain a communication network created in the network.

  The communication means in the street lamp of the present invention may be connected to the Internet. As a result, the victims can access the Internet by connecting their mobile terminals to the nearest street light.

The street light of the present invention may be provided with a camera capable of capturing an image of the surroundings, and an image captured by the camera may be transmitted via the communication means. This feature is based on the assumption that the combination of a street light having a light emitting means that emits light and a main body that supports the light emitting means at a required height, and other techniques described in the present application. It is possible to establish and implement the present invention as a street light that is not premised on being used independently and without being combined, and that a plurality of lamps are not used as a set.
The image in this case may be either a still image or a moving image. By transmitting the image, the state of the victim can be confirmed, for example, by a third party in a remote place. This is useful for confirming the presence or absence of a rescuer.

The street light of the present invention includes a sensor capable of measuring at least one of external parameters, and can transmit information about the parameter measured by the sensor via the communication means. May be. This feature is based on the assumption that the combination of a street light having a light emitting means that emits light and a main body that supports the light emitting means at a required height, and other techniques described in the present application. It is possible to establish and implement the present invention as a street light that is not premised on being used independently and without being combined, and that a plurality of lamps are not used as a set.
Examples of parameters in this case are temperature, humidity, water level, and radiation dose, but are not limited thereto. By sending these parameters to the outside, for example, to a third party in a remote place, it is possible to use it for grasping the state of the victim.

The street lamp of the present invention includes a light emission state control means for changing the light emission state of the light emission means, and the light emission state control means changes the light emission state of the light emission means, thereby providing information to the victim. You may be able to communicate. This feature is based on the assumption that the combination of a street light having a light emitting means that emits light and a main body that supports the light emitting means at a required height, and other techniques described in the present application. It is possible to establish and implement the present invention as a street light that is not premised on being used independently and without being combined, and that a plurality of lamps are not used as a set.
Examples of changing the light emission state of the street lamp include changing the color of light, changing the amount of light, changing the presence / absence of blinking, and the blinking interval, or combining them. By changing the light emission state of the street lamp, there is a possibility that information can be provided to the victim in a state that can be intuitively understood. In this case, the street lamp may be used in combination with an operating device operated by the manager of the street lamp. The operating device can control the street light by the operation, and thereby the light emitting state of the light emitting means of the street light can be individually changed.
This invention can be made more meaningful by applying it to the street lamp set of the present invention. For example, each of the street lamps included in the street light set includes a light emission state control unit that changes a light emission state of the light emitting unit, and the light emission state control unit changes the light emission state of the light emission unit. The information may be transmitted to the victims. In that case, the street light set includes an operation device operated by an administrator of the street light, and the operation device can individually control each of the street lights by the operation, thereby Information on the entire street light set may be transmitted to a disaster victim by individually changing the light emission state of each light emitting means of the street light. This allows the victim to obtain more information than can be obtained from only one street light. This can be used, for example, when evacuating a victim.

The street lamp of the present invention may include a battery that supplies power for the light emitting means to emit light when a disaster occurs. This feature is based on the assumption that the combination of a street light having a light emitting means that emits light and a main body that supports the light emitting means at a required height, and other techniques described in the present application. It is possible to establish and implement the present invention as a street light that is not premised on being used independently and without being combined, and that a plurality of lamps are not used as a set.
In the event of a disaster, the supply of power to street lights may be interrupted. Even in such a case, if a battery is present, the light emitting means can be illuminated by supplying power to the light emitting means.
The destination to which the battery supplies power is not limited to the light emitting means, but the battery also supplies power to other members in the street light that require power, such as cameras, communication means, sensors, and the like. Of course it does not matter. Of course, the battery may function other than during a disaster.
When the street lamp of the present invention has a battery, the street lamp may be capable of power generation using renewable energy, and may include power generation means for supplying the generated power to the battery. According to this, it becomes possible to lengthen the time during which the battery functions. Examples of renewable energy are sunlight and wind power.
Of course, the power generation means may function at times other than disasters.
When the street light of the present invention has a battery, the street light may include a power supply terminal connected to the battery and capable of feeding the power stored in the battery to the outside. The street lamp of the present application demonstrates its true value in communication with a portable terminal possessed by a disaster victim. On the other hand, if the mobile terminal of the victim is out of charge, the street light of the present invention cannot demonstrate its true value. If the battery has a power supply terminal, it is possible to supply power to the victim's mobile terminal from the streetlight battery, so that it is possible to prevent a situation where the victim's mobile terminal is out of charge. Of course, if power can be supplied to devices other than mobile terminals, it will greatly help the victims. The power supply terminal may be a known or known one, such as an outlet or a USB terminal.

The main body may include a storage provided with a door that can be opened and closed, and the storage may be configured to store a stockpile. By storing the stockpile in such a storage, the victim can use the stockpile during a disaster. This feature is based on the assumption that the combination of a street light having a light emitting means that emits light and a main body that supports the light emitting means at a required height, and other techniques described in the present application. It is possible to establish and implement the present invention as a street light that is not premised on being used independently and without being combined, and that a plurality of lamps are not used as a set.
The door includes a key that is unlocked by a predetermined operation, and cannot be opened unless the key is unlocked. The operation for unlocking is, for example, input of a personal identification number. By preliminarily transmitting the personal identification number only to the local residents, it is possible to prevent the stored items from being stolen by a person other than the local residents at the time of the disaster or before the disaster.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows an overview of a street lamp 1 in this embodiment. As will be described later, the street lamp 1 is used as a street lamp set including a number of street lamps 1.

As shown in FIG. 1, the street lamp 1 includes a base part 11, a stockpile part 12, a column part 13, and an illumination part 14.
A part of the base part 11, the stockpile part 12, the support | pillar part 13, and the illumination part 14 makes the main-body part in this invention.

The foundation 11 is a foundation of the street lamp 1 and supports the street lamp 1 with its lower end fixed to the ground. Although not limited thereto, in this embodiment, the base portion 11 is made of metal, and is not limited thereto, but has a rectangular parallelepiped shape in plan view. The base portion 11 is hollow, and a battery 111, a sensor 112, and a control circuit 113 are built in the hollow portion.
The base portion 11 is also provided with a first door 114 that is a door that can be opened and closed.

The battery 111 is a secondary battery that can be discharged and charged. As long as such a function is satisfied, the configuration of the battery 111 is not limited. For example, a lithium ion secondary battery can be used as the battery 111. The battery 111 is controlled to be discharged and charged by the control circuit 113.
In this embodiment, the battery 111 supplies power to the light emitter 142 at least after a disaster occurs. Although not necessarily limited to this, the battery 111 in this embodiment supplies power to the sensor 112, the control circuit 113, a camera (described later), a wireless LAN communication mechanism (described later), etc. at least when a disaster occurs. Each process performed by the street lamp 1 is thereby maintained.

The sensor 112 is for measuring some parameter outside the street light 1. Examples of parameters are temperature, humidity, water level, and radiation dose, but are not limited thereto. When the parameter is temperature, the sensor 112 is a thermometer, when the parameter is humidity, the sensor 112 is a hygrometer, when the parameter is a water level, the sensor 112 is a water level meter, and the parameter is a radiation dose. In this case, the sensor 112 is a dosimeter. Any of these may be known ones. A plurality of sensors 112 may be present for measuring each of a plurality of parameters. In this embodiment, the number of sensors 112 is four to measure the four parameters described above, but the number of sensors 112 is naturally not limited to four. The sensor 112 is connected to the control circuit 113 by a cable (not shown), and sends information about each parameter generated by the sensor 112 to the control circuit 113.
Note that if the sensor 112 is present inside the base portion 11, at least a part of the sensor 112 may be exposed to the outside of the base portion 11 or the like if there is a situation in which a parameter to be measured cannot be measured. Absent.

The control circuit 113 controls the operation of the street lamp 1. The control circuit 113 is configured to include, for example, a computer, and the hardware configuration of the computer may be a known or known one. The computer includes a CPU, a ROM, a RAM, an interface, and the like.
When receiving the above-mentioned information from the sensor 112, the control circuit 113 sends it to a wireless LAN communication mechanism described later via a cable (not shown). When the control circuit 113 receives image data (to be described later) from a camera (to be described later), it sends it to a wireless LAN communication mechanism (to be described later) via a cable (not shown). The control circuit 113 also receives an input from an input key (to be described later) and controls whether or not to permit the unlocking of a key provided on the second door (to be described later).
When the control circuit 113 receives a control signal (to be described later) from an operating device (to be described later), the control circuit 113 controls a light emitting unit (to be described later) accordingly. The control circuit 113 may receive a control signal from a wireless LAN communication mechanism, which will be described later, or may receive a control signal in a wired manner by connecting to the operation device through a dedicated line, for example.

The first door 114 is a door that can be freely opened and closed. But the 1st door 114 may be provided with the key unlock | released only when predetermined | prescribed operation is made like the case of the 2nd door mentioned later.
The state which opened the 1st door 114 is shown in FIG. A recess is provided in the back of the first door 114. And the electric power feeding terminal 115A-C is provided in the recessed part. The power supply terminals 115 </ b> A to 115 </ b> C are connected to the battery 111 so that the power stored in the battery 111 can be supplied to an external device.
The feed terminals 115A-C can be different types of feed terminals, which is the case in this embodiment. The power supply terminal 115A is a known outlet. The power supply terminal 115B is a known USB terminal. The power supply terminal 115C is mainly used for charging a smartphone, and is also a known microUSB terminal or Lightning terminal. The power supply terminals 115A to 115C are not limited to the above-described three types, but it would be helpful for disaster victims to prepare several types of power supply terminals.

The stockpiling part 12 is fixedly mounted on the base part 11. The stockpiling unit 12 has a function for stockpiling stockpiled items. As long as it is possible, the configuration of the storage unit 12 is free, but in this embodiment, the storage unit 12 is made of metal, and although not limited thereto, it has a circular cylindrical shape in plan view. . The storage section 12 is hollow, and the entire hollow internal space functions as a storage, and a storage product (not shown) is stored in the storage. .
Examples of stockpile products are LED lanterns, dry batteries, mobile phone chargers, manual power generation lights, radios, blankets, aluminum deposited heat insulation sheets, disposable warmers, drinking water, preserved foods, emergency toilets, changing clothes, deodorants, Pharmaceuticals, sanitary products, disposable diapers, etc. Of course, other stocks may be stored in the storage, or different stocks may be stored for each storage of each street light 1.
The stockpiling part 12 is provided with the 2nd door 121 which is a door, By opening the 2nd door 121, the inside of a storage is exposed. The second door 121 is provided with a key (not shown) that is unlocked only when the disaster victim performs a predetermined operation. Although not limited to this, the second door 121 is provided with an input key 122 that is a numeric keypad in this embodiment, and only when an appropriate operation is performed on the input key 122. The key of the two-door 121 is unlocked.
Specifically, the input content from the input key 122 is sent to the control circuit 113 described above. When the input content from the input key 122, for example, the input 4-digit password is correct, the control circuit 113 unlocks the key of the second door 121. When the key is unlocked, the second door 121 can be released, and only after the second door 121 can be released, the disaster victim can take out the stored item from the storage of the storage unit 12.
Such a key is for preventing a stored item from being stolen by a malicious third party regardless of the occurrence of a disaster. The operation for unlocking the predetermined key is notified in advance to those who are scheduled to use the stockpile stored in each street light 1 such as neighbors. Is preferred.

  The support column 13 is a column that supports the illumination unit 14. In this embodiment, the support column 13 has a long circular circular shape in plan view, and the lower end thereof is fixed to the upper surface of the storage unit 12. Although not limited to this, in this embodiment, the illumination unit 13 is fixed near the upper end of the support column unit 13.

The illumination unit 14 corresponds to illumination in a normal street lamp, but the illumination unit 14 in the street lamp 1 also has functions other than the illumination function.
Although not restricted to this, the illumination part 14 in this embodiment is comprised by the rectangular plate shape by planar view, as shown in FIG.1 and FIG.3. The illumination unit 14 is partially penetrated by the support column 13. Further, both ends of the illuminating unit 14 are fixed to the tip of a suspension line 131 which is a strong linear body composed of a wire or the like, the base end of which is fixed to the upper end of the support column 13. The suspension line 131 reinforces the fixing of the illumination unit 14 by the support column 13.

A photovoltaic power generation panel 141 is provided on the upper surface of the illumination unit 14. The photovoltaic power generation panel 141 performs photovoltaic power generation. As long as it is possible, a known or well-known photovoltaic power generation panel 141 can be used. The photovoltaic power generation panel 141 is connected to the above-described battery 111 by a cable (not shown), and the power generated by the photovoltaic power generation panel 141 is stored in the battery 111.
Note that the solar power generation panel 141 can be replaced with a generator that can supply power to the battery 111 and that can generate power using renewable energy. For example, it is possible to replace a known wind power generator with the solar power generation panel 141.

Below the illumination unit 14, a light emitter 142, a camera 143, and a wireless LAN communication mechanism 144 are provided.
The light emitter 142 is a light source that can emit light as illumination light. For example, an LED lamp, a fluorescent lamp, or the like can be used as the light emitter 142. In this embodiment, although not limited thereto, the light emitter 142 can emit light of any color or several colors. The manner in which the light emitter 142 emits light is determined by the control performed by the control circuit 113.
The light emitter 142 is lit by power supplied from the battery 111 at least when a disaster occurs. In a state where no disaster has occurred, the light emitter 142 may be lit with the power supplied from the battery 111, or lit with the power transmitted from the power plant through the electric wire. It doesn't matter. When it is necessary to switch the supply source of the power used for the light emitter 142 to emit light, the control circuit 113 performs the control.

The camera 143 is for imaging the surroundings of the street light 1. The camera 143 in this embodiment is fixedly attached to the lower surface of the illumination unit 14 and can take an image of a victim who is mainly under the street light 1. As long as it is possible, the camera 143 may be a known one. An image captured by the camera 143 may be a still image or a moving image. In this embodiment, the direction in which the camera 143 captures an image is fixed vertically below the camera 143. However, if the image capturing direction of the camera 143 is fixed, a wider angle of view is preferable. On the other hand, the direction of the camera 143 can be changed by changing the direction of the camera 143 depending on time.
Data about an image captured by the camera 143 is sent to the control circuit 113 via a cable (not shown).

The wireless LAN communication mechanism 144 performs ad hoc wireless LAN communication with the wireless LAN communication mechanism 144 provided in the other street lamps 1. As will be described in detail later, the street light 1 of this embodiment constitutes a street light set by being combined with a number of street lights 1. A number of street lamps 1 participate as the wireless LAN communication mechanism 144 of each street light 1 performs ad-hoc wireless LAN communication with the wireless LAN communication mechanism 144 included in at least one other street light 1. A communication network is configured.
On the other hand, the wireless LAN communication mechanism 144 can communicate with a portable terminal (not shown) possessed by a disaster victim via a wireless LAN. Note that the wireless LAN communication mechanism 144 may be configured to be able to perform ad hoc wireless LAN communication with a mobile terminal possessed by a disaster victim (which may of course be a mobile terminal possessed by a person other than the disaster victim). By doing so, since the portable terminal which a disaster victim has also participates in the above-mentioned communication network made by many street lamps 1 participating, the communication network becomes easier to maintain.
Since the wireless LAN communication mechanism 144 capable of performing communication as described above is known or well known, detailed description of its configuration is omitted.
Moreover, the example of a portable terminal is a smart phone and a tablet. Examples of smartphones include the iPhone (TM) series manufactured and sold by Apple Japan GK. An example of the tablet is the iPad (trademark) series manufactured and sold by the company.

FIG. 4 shows an installation example when the street light 1 as described above is installed in a city.
In the figure, P is a road. Although not limited to this, a large number of street lamps 1 are arranged on both sides of the road P in this example. The interval between the adjacent street lamps 1 may or may not be constant, but in this example, for example, it is constant at intervals of 50 m. A group of street lamps 1 partially shown in FIG. 4 constitutes a street lamp set.
In the figure, Q is a local government building. It is assumed that the local government that manages this public building Q also serves as the manager of the street light set. In the public building Q, there is an operating device Q1. The operating device Q1 is an ordinary computer and can generate a control signal and send it to each street light 1. The control signal is a signal for specifying how to turn on the light emitter 142 in each street light 1. The control circuit 113 of each street lamp 1 that has received the control signal turns on the light emitter 142 of the street lamp 1 based on the content specified by the control signal.

As described above, the wireless LAN communication mechanism 144 of each street light 1 performs ad hoc wireless LAN communication with the wireless LAN communication mechanism 144 provided in at least one other street light 1. In this embodiment, as shown in FIG. 5, the wireless LAN communication mechanism 144 of all the street lamps 1 performs ad hoc wireless LAN communication with the wireless LAN communication mechanism 144 included in the plurality of street lamps 1. To do.
For example, the street lamp 1A in the figure can perform ad hoc wireless LAN communication with five street lamps 1 located in a circle drawn by a broken line with the center thereof. In addition, the street light 1B in the figure can perform ad hoc wireless LAN communication with the three street lights 1 located in a circle drawn by a broken line with the center thereof. The same applies to the other street lamps 1.

In addition, at least one of the street lamps 1 constituting the street lamp set is connected to the Internet. The connection to the Internet here means a connection without passing through another street lamp 1. The connection to the Internet may be made by wire or wirelessly.
If at least one of the street lamps 1 constituting the street lamp set is connected to the Internet, the entire communication network formed by the street lamp set can be connected to the Internet. The victims who can connect from the nearest street light 1 using their own mobile terminals can also have an environment where they can connect to the Internet.
If more of the street lamps 1 are connected to the Internet as described above, it is easier to maintain a connection between the communication network formed by the street lamp set and the Internet.

The use method and operation of the street light 1 and street light set described above will be described.
The street lamp 1 is disposed along the road P as shown in FIG. The street light 1 is used in the same way as a normal street light during normal times. Each street light 1 functions as a lighting device in the same manner as a normal street light by the light emitter 142 emitting light. As described above, in the street light 1 of this embodiment, what is stored in the battery 111 is not used as power for the luminous body 142 to emit light during normal times, and is not used from the power plant via an electric wire (not shown). The transmitted power is used. The control circuit 113 performs the control.
In addition, storage items are stored in the storage of each street light 1. Information on the predetermined operation for unlocking the key of the second door 121, which is a storage door, uses stockpile stored in each street light 1 during normal times. Notify those who are scheduled to do so.

Next, suppose that disasters such as earthquakes, tsunamis, river floods, large-scale fires, and accidents at nuclear power plants occurred.
In that case, the victims gather at each street light 1 in search of a safe material of light, especially at night. However, if the function of the street lamp 1 is informed at a normal time by a local government or the like, the disaster victims will gather around the street lamp 1 not only at night.

The sensor 112 measures the temperature, humidity, water level, and radiation dose outside the street light 1. These measurements may be continuous in time, but may be batch-wise at intervals of 30 minutes or the like. In any case, information generated by each sensor 112 measuring some parameter is transmitted from the control circuit 113 via the wireless LAN communication mechanism 144 and, if necessary, via several street lamps 1. Sent to the outside. Note that the information generated by the sensor 112 may be sent to the outside, for example, by wire without passing through the wireless LAN communication mechanism 144. In any case, these processes are preferably performed automatically.
Public building Q is an example of the “outside” to which such information is sent. By providing information related to the public building Q, it becomes possible for the local government that manages the public building Q to grasp various parameters relating to the victims. As a result, it becomes possible to increase the efficiency of the rescue of the victims, or to appropriately alert the victims.
In addition, the camera 143 starts imaging around the street lamp 1. An image captured by the camera 143 is sent to the control circuit 113, and is sent to the outside via the wireless LAN communication mechanism 144 via some street lamps 1 if necessary. Note that the image captured by the camera 143 may be sent to the outside, for example, by wire without passing through the wireless LAN communication mechanism 144. In any case, these processes are preferably performed automatically.
Public building Q is an example of the “outside” to which these pieces of information are sent. By providing information relating to the public building Q, it becomes possible for the local government managing the public building Q to grasp the situation of the victims near each street light 1 by an image. Thereby, it becomes possible to determine the priority of rescue of the disaster victims, or to appropriately alert the victims.

On the other hand, victims have access to the above-described communication network formed by the cooperation of many street lamps 1 by connecting their mobile terminals to the wireless LAN communication mechanism 144 of the nearest street lamp 1. Will be able to. For example, if the local government has a virtual safety confirmation bulletin board on such a communication network, each disaster victim may use his mobile terminal to write his / her safety on the bulletin board, or to other disaster victims. The information written on the bulletin board can be read about the person.
Further, if the communication network is connected to the Internet, each disaster victim can connect to the Internet by connecting to the communication network using his mobile terminal. As a result, it is possible to access terminals connected to the Internet at a further distance, more specifically, the world. This solves the problem of lack of information in the victims.
If a portable terminal possessed by a person in the vicinity of a street light set such as a victim has a function of performing an ad hoc wireless LAN communication similar to the wireless LAN communication mechanism 144 of the street light 1, those portable terminals The terminal also forms part of the communication network described above, and it can be said that it is preferable.

In addition, the victim operates the input key 122 according to the operation content obtained during normal time as described above to unlock the key of the second door 121. By doing so, the 2nd door 121 comes to open.
When the second door 121 is opened, the stockpile as described above is in the storage. By taking out these stockpile items from the storage, it is easier for victims to get over the period when they are most likely to fall short of supplies immediately after the disaster.

  Further, the disaster victim opens the first door 114 as necessary. When the first door 114 is opened, there are power supply terminals 115A to 115C. The victim can supply power to his / her mobile terminal and other electrical devices from the power supply terminals 115 </ b> A to 115 </ b> C.

If necessary, the administrator of the public building Q operates the operating device Q1 to generate a control signal and sends it to each street light 1.
Receiving it, the control circuit 113 of each street lamp 1 turns on the light emitter 142 of the street lamp 1 based on the content specified by the control signal. Examples thereof include the following.
For example, in FIG. 6, the light-emitting body 142 of the street lamp 1 in the range surrounded by the broken line indicated by R emits red light, and similarly, the street in the range surrounded by the broken line indicated by Y Assume that the light emitter 142 of the street lamp 1 emits yellow light, and the light emitter 142 of the street lamp 1 in the range surrounded by the broken line indicated by G emits green light. And since these three colors are also used for traffic lights, it may not be necessary to educate the victims in advance. However, when the light-emitting body 142 of the street light 1 is shining red during the normal time, the surrounding area Suppose that educating residents in the area where there is a set of street lamps, it is dangerous, when it glows yellow, it is somewhat dangerous, and when it glows green, it is safe. Then, as shown in FIG. 6, when the light emitter 142 of each street light 1 is turned on, the victim is guided to one set of street lights rather than each street light 1, and downward in FIG. 6. It will go on the way.
Thus, by controlling the lighting method of the light emitter 142 of the street lamp 1, more information than can be given to the victim from each street lamp 1 can be given from the street lamp set. However, the disaster victim can also understand the situation where he / she is placed now by looking at the color of the luminous body 142 of the nearest street lamp 1.
In order to give more information than the individual street lamps 1 can give to the victims from the street lamp set, it is necessary to appropriately change the lighting method of the light emitter 142 of each street lamp 1. The method for changing the lighting method of one light emitter 142 is not limited to the color of light emitted from the light emitter 142. For example, the lighting method of the light emitters 142 of each street light 1 can be changed by changing the brightness of the light emitters 142 or blinking the light emitters 142.

  In order to realize the processing as described above, the battery 111 supplies power not only to the light emitter 142 but also to the sensor 112, the control circuit 113, the camera 143, the wireless LAN communication mechanism 144, and the like. As a result, the electric power stored in the battery 111 is reduced by supplying power to the outside through the power supply terminals 115A to 115C. On the other hand, the electric power generated by the photovoltaic power generation panel 141 is stored in the battery 111. Of course, if the power supply from the power plant through the electric wire is alive even after a disaster occurs, it is of course free to use it instead of or in addition to the electric power of the battery 111. The control may be performed by the control circuit 113.
