As shown in FIG. 2, the instruction information providing system includes an instruction information providing apparatus 10 (10A to 10C in FIG. 2), a disaster information distribution server apparatus 20, and a sensor 30.
The disaster information distribution server device 20 is a server device installed for each local government such as a prefecture, city, or ward. The disaster information distribution server device 20 collects disaster information of the area in real time. The disaster information distribution server device 20 is connected to one or a plurality of instruction information providing devices 10 (10A to 10C) via a network. The disaster information distribution server device 20 stores network information such as the location information and IP address of the installation location of each instruction information providing device 10 in association with each instruction information providing device 10.
When a disaster occurs in the area, the disaster information distribution server device 20 notifies the instruction information providing device 10 installed near the disaster occurrence location of the occurrence of the disaster, for example. When the instruction information providing device 10 receives a notification of the occurrence of a disaster from the disaster information distribution server device 20, the instruction information (eg, “XXX has occurred. Evacuated to XXX. Please ").

The instruction information providing apparatus 10 is connected to one or more sensors 30. The sensor 30 transmits information detected by the sensor 30 or information obtained by analyzing the detected information to the instruction information providing apparatus 10. For example, when the sensor 30 is an image sensor (camera), the information obtained by analyzing the detected information is information (for example, “a person is included in an image”) analyzed by an image processing circuit mounted on the image sensor. Etc. ”). Or when the sensor 30 is a fire alarm device, it is the alarm signal which the fire alarm device determined to generate fire and output.
The information detected by the sensor and the information analyzed and output by the sensor are collectively referred to as sensor information. In the instruction information providing device 10, the sensor information acquisition unit 11 acquires the sensor information transmitted from the sensor 30, and the determination unit 12 determines the situation. Further, the output unit 13 outputs an instruction signal according to the determination of the determination unit 12 and the installation position of the sensor.

The instruction information providing apparatus 10 includes a sensor information acquisition unit 11, a determination unit 12, an output unit 13, a display unit 14, a communication unit 15, a storage unit 16, and a power supply unit 17.
The sensor information acquisition unit 11, the determination unit 12, and the output unit 13 are as described with reference to FIG.
The display unit 14 is a display device such as an LCD (liquid crystal display) or electronic paper. Since power consumption can be kept low, electronic paper is suitable for the display unit 14.

FIG. 3 is a diagram illustrating an example of an instruction information providing apparatus according to an embodiment of the present invention.
FIG. 3 is a front view of the instruction information providing apparatus 10. As illustrated in FIG. 3, the instruction information providing apparatus 10 includes a display unit 14. The display unit 14 is, for example, electronic paper. Various instruction information is displayed on the display unit 14. For example, as shown in FIG. 3, instruction information for guiding a fire occurrence place and an evacuation route may be displayed.

FIG. 4 is a first diagram illustrating a usage example of the instruction information providing apparatus according to the embodiment of the present invention.
FIG. 4 is a cross-sectional view of the building 1 to which the instruction information providing device 10 is attached. Buildings are, for example, public facilities such as stations and libraries, commercial facilities, underground passages, and the like.
On the wall surface of the building 1, a plurality of instruction information providing devices 10 (10 A to 10 C) are provided at positions that are visible to the person 100. The wall surface of the building 1 includes temperature sensors 30A to 30C, water level sensors 30D to 30E, and an earthquake sensor 30F as examples of the sensor 30.
Moreover, the fire extinguisher 40 is provided near the attachment position of the instruction information providing apparatus 10C. Further, it is assumed that the temperature sensors 30A to 30C, the water level sensors 30D to 30E, and the earthquake sensor 30F can communicate with the instruction information providing devices 10A to 10C.
Usually, the display unit 14 of the instruction information providing apparatus 10 displays arbitrary information such as advertisements, a guide map of the building 1, a weather forecast, and a timetable if it is a station. However, when a disaster such as an earthquake occurs, for example, the instruction information providing apparatus 10 displays the disaster information received from the disaster information distribution server apparatus 20 and the instruction information for the disaster.
For example, when an earthquake occurs, the instruction information providing apparatus 10 receives information such as the seismic intensity of the epicenter and the area where the own apparatus is installed from the disaster information distribution server apparatus 20 via the communication unit 15. Next, the determination unit 12 determines that “an earthquake has occurred” based on the received information, and outputs information on the epicenter and the seismic intensity to the output unit 13. The output unit 13 outputs to the display unit 14 instruction information such as “An earthquake of seismic intensity X occurred at XX time and XX minutes.

In this way, the instruction information providing apparatus 10 obtains disaster information from the disaster information distribution server apparatus 20 when a disaster occurs, and displays the instruction information for ensuring the safety of people around the instruction information providing apparatus 10. be able to.
However, if only the instruction information is displayed depending on the disaster information distribution server device 20, for example, if the disaster information distribution server device 20 is out of order and the location of the disaster information distribution server device 20 is close, the disaster information distribution server device 20 will fail. Provide instruction information when the communication network infrastructure with the server device 20 is damaged or when traffic to the disaster information distribution server device 20 is concentrated and communication with the disaster information distribution server device 20 cannot be performed. The device 10 cannot obtain information from the disaster information distribution server device 20, and cannot display the instruction information.
In addition, it is conceivable that the disaster information distributed from the disaster information distribution server device 20 is wide-area information or information after a little time has elapsed, and information obtained from the disaster information distribution server device 20 However, it is conceivable that the instruction information providing apparatus 10 is not suitable for the installation position.
Therefore, in the present embodiment, an instruction information providing apparatus 10 that can autonomously determine the occurrence of a disaster based on the sensor information acquired from the sensor 30 and display the instruction information according to the situation is provided. Next, the process in which the instruction information providing apparatus 10 autonomously determines the situation and outputs the instruction information will be described using some examples.

[In case of earthquake]
When an earthquake occurs, the earthquake sensor 30F detects vibration. The earthquake sensor 30F estimates the seismic intensity of the earthquake from the magnitude of the detected vibration and transmits the information to the instruction information providing devices 10A to 10C. The operation of the instruction information providing apparatus 10A will be described as an example. The sensor information acquisition unit 11 acquires seismic intensity information from the earthquake sensor 30F, and outputs the acquired seismic intensity information to the determination unit 12.
For example, the determination unit 12 determines that an earthquake has occurred if an earthquake having a seismic intensity of a certain magnitude or more occurs a predetermined number of times within a unit time. When the determination unit 12 determines that an earthquake has occurred, the determination unit 12 outputs the determination result and seismic intensity information to the output unit 13.
For example, the seismic strength of the building 1 is recorded in the storage unit 16, and the output unit 13 sets the determination result of the determination unit 12 (“earthquake of seismic intensity X occurs at time XX: XX”) and the installation of the earthquake sensor 30 F. Instruction information corresponding to the position (“building 1”) and the installation position of the instruction information providing apparatus 10A (“position in the building 1”) is output.
For example, if the seismic intensity information obtained from the judgment unit 12 is less than the seismic strength, the output unit 13 will say, “An earthquake of seismic intensity X occurred at time XX: XX. Output instruction information (instruction information 1).
Further, for example, when the building 1 is a commercial facility and there is a product shelf near the instruction information providing device 10A, and the seismic intensity information acquired from the determination unit 12 is larger than a predetermined threshold, the output unit 13 In addition to the above instruction information 1, instruction information such as “Please be careful about falling products” and “Please move to XXX because this area is dangerous” is output.
Further, for example, when the instruction information providing device 10A is provided in a passage that leads to a safe place in the building 1, in addition to the instruction information 1, instruction information such as “Please proceed in the direction of the arrow along this passage” is output. To do.
Instruction information corresponding to the situation (seismic intensity) determined by the determination unit 12 and the installation position of the instruction information providing device 10 is recorded in advance in the storage unit 16 for each instruction information providing device 10, and the output unit 13 This information is read out and output.

In addition, based on the elapsed time from the occurrence of the earthquake and the number of earthquakes detected during that time and the magnitude of the seismic intensity, when the earthquake continues continuously, the determination unit 12 continuously generates the earthquake. And the determination result is output to the output unit 13. The output unit 13 outputs instruction information (for example, “please secure an evacuation route”, “please pay attention to the occurrence of a fire”, etc.) for preventing a secondary disaster due to the continuation of the earthquake.
For example, when the magnitude and number of occurrences of an earthquake occurring within a predetermined time from the occurrence of the earthquake are equal to or less than a threshold value, the determination unit 12 determines the convergence of the earthquake and outputs the determination result to the output unit 13. The output unit 13 is recorded in association with the determination result (“convergence”), the sensor installation position (“building 1”), and the installation position of the own apparatus (“position in the building 1”), for example, building 1 The instruction information that permits the user to go outside is read from the storage unit 16 and output.
Thus, according to the present embodiment, the occurrence or convergence of a disaster is determined in real time according to the sensor information detected by the sensor 30 (earthquake sensor 30F) installed at a relatively short distance, and the sensor 30 Instruction information according to the installation position and the installation position and status of the instruction information providing apparatus 10 can be output.
In addition, since the instruction information providing apparatus 10 includes the power supply unit 17, the instruction information can be output even if the infrastructure of the power system stops functioning due to an earthquake. Moreover, since the instruction information providing apparatus 10 can autonomously determine the disaster situation based on the sensor information acquired by the sensor information acquisition unit 11 and output the instruction information, the communication infrastructure functions due to the earthquake. Even if the communication with the disaster information distribution server device 20 is lost, the instruction information can be output.

The instruction information providing device 10 can display the instruction information independently based on the sensor information acquired from the sensor 30. However, when communication with the disaster information distribution server device 20 is possible, the disaster information It is also possible to display disaster information obtained from the distribution server device 20 via the communication unit 15 together.
In consideration of safety, the determination unit 12 selects the larger value of the seismic intensity information acquired from the disaster information distribution server device 20 and the seismic intensity information acquired from the earthquake sensor 30F, and selects the selected value. It may be determined that an earthquake with a seismic intensity of.

Further, for example, depending on the disaster response policy determined by each local government where the disaster information distribution server device 20 is provided, the analysis capability of the disaster information distribution server device 20, etc. The instruction information providing apparatus 10 transmits the sensor information acquired from the sensor 30 to the disaster information distribution server apparatus 20, and displays the instruction information as a result of analyzing the sensor information by the disaster information distribution server apparatus 20. Only when the communication with the disaster information distribution server device 20 is down, the instruction information providing device 10 autonomously determines the situation based on the sensor information from the sensor 30 and displays the instruction information. You may do it.

[In case of fire]
In the case of a fire, for example, if a fire occurs near the instruction information providing device 10A, the temperature sensor 30A first detects a high temperature. The temperature sensor 30A transmits the detected temperature to the instruction information providing devices 10A to 10C.
In the instruction information providing apparatus 10 A, the sensor information acquisition unit 11 acquires information on the temperature sensor 30 A and outputs the information to the determination unit 12. For example, the determination unit 12 determines that a fire has occurred in the vicinity of the temperature sensor 30 A when temperature information equal to or greater than a predetermined threshold is acquired a predetermined number of times or more. If the determination unit 12 determines that a fire has occurred, the determination unit 12 outputs the determination result to the output unit 13.
Similarly, also in the instruction information providing apparatus 10B, the determination unit 12 determines that a fire has occurred near the temperature sensor 30A based on the temperature information acquired from the temperature sensor 30A. The same applies to the instruction information providing apparatus 10C.
Each of the instruction information providing apparatuses 10A to 10C that has determined that a fire has occurred in the vicinity of the temperature sensor 30A can display different instruction information based on the installation position of the temperature sensor 30A and the installation position of its own apparatus. .
Note that the storage unit 16 of the instruction information providing apparatus 10A records position information of the installation positions of the instruction information providing apparatus 10A and the temperature sensors 30A to 30C. The same applies to the instruction

information providing apparatuses

10B and 10C.

For example, in the case of the instruction information providing apparatus 10A, the output unit 13 determines, for example, “A fire has occurred near this time XX: XX based on the installation position of the temperature sensor 30A and the installation position of the instruction information providing apparatus 10A. "Please evacuate.", "The fire has occurred at this time XX: XX. Please notify the fire department."
Further, in the case of the instruction information providing device 10B, the output unit 13 generates a fire in the direction of XXX, for example, “at time XX: XX,” based on the installation position of the temperature sensor 30A and the installation position of the instruction information providing device 10B. The direction of XXX is dangerous.Please evacuate in the direction of XXX where the evacuation exit is located (for example, please evacuate in the direction opposite to the installation position of the temperature sensor 30A as viewed from the instruction information providing device 10B). (Instruction information 2) is output.
Further, in the case of the instruction information providing apparatus 10C, the output unit 13 adds to the instruction information 2 based on the installation position of the temperature sensor 30A and the installation position of the instruction information providing apparatus 10C. The instruction information is output. The person in charge of disaster prevention of the building 1 can carry out the fire extinguishing activity by carrying the fire extinguisher 40 to the place where the fire occurs by seeing this display.
The instruction information is recorded in advance in the storage unit 16 based on the position of the evacuation exit or the position of the fire extinguisher for each installation position of the sensor 30 (fire occurrence detection position) and the installation position of the own device. The output unit 13 of each instruction information providing device 10 reads out the instruction information from the storage unit 16 and outputs it using the position of the temperature sensor 30 A that has detected the occurrence of a fire acquired from the determination unit 12 and the position of its own device.

In addition, in a scene where a fire is being extinguished by fire extinguishing activities after the occurrence of a fire, for example, the average value of the temperature information acquired from the temperature sensor 30A via the sensor information acquisition unit 11 during a predetermined period is When the temperature information is lower than the average value of the temperature information acquired during the predetermined period, or when the temperature information fluctuation during the predetermined period indicates that the temperature near the temperature sensor 30A is decreasing, the determination unit 12 Is determined to be extinguished. The same applies to the instruction

information providing apparatuses

10B and 10C.
In this case, for example, in the instruction information providing apparatus 10B, the output unit 13 determines, for example, based on the situation determined by the determination unit 12, the installation position of the temperature sensor 30A, and the installation position of the instruction information providing apparatus 10B. At time XX: At XX, the occurrence of a fire was detected in the direction of XXX. The fire is now extinguished. Please evacuate in the YY direction with the evacuation exit.
In addition, when the fire is completely extinguished, the determination unit 12 of the instruction information providing apparatus 10A determines that the fire has occurred based on the fact that the average value of the temperature information acquired by the sensor information acquisition unit 11A from the temperature sensor 30A has returned to normal temperature. It is determined that the fire has been extinguished. Then, the output unit 13 outputs instruction information such as, for example, “The fire that occurred at time XX: XX has been extinguished. The direction of XXX is currently closed. Please use another passage.” The same applies to the instruction

information providing apparatuses

10B and 10C.

Moreover, in the scene where the fire is spreading, in addition to the temperature sensor 30A, the temperature sensor 30B detects a high temperature. The temperature sensor 30B transmits the detected temperature to the instruction information providing devices 10A to 10C.
For example, in the instruction information providing apparatus 10A, the determination unit 12 determines that a fire has occurred near the temperature sensor 30A and the temperature sensor 30B based on the temperature information acquired by the sensor information acquisition unit 11 from the

temperature sensors

30A and 30B. . In addition, the determination unit 12 determines that the fire has spread together with the determination that “a fire has occurred near the temperature sensor 30A” performed a predetermined time ago.
In the instruction information providing apparatus 10B, the determination unit 12 performs the same determination. The same applies to the instruction information providing apparatus 10C.
In this case, for example, in the instruction information providing apparatus 10C, the output unit 13 determines, for example, based on the situation determined by the determination unit 12, the installation positions of the

temperature sensors

30A and 30B, and the installation position of the instruction information providing apparatus 10C. "At time XX: XX, the occurrence of a fire was detected in the direction of XX. The fire is currently spreading. Urgently, the direction of the XXX where the escape door is located (for example, the temperature sensor 30A, Please evacuate to the direction opposite to the installation position of 30B. "

According to the present embodiment, since the determination unit 12 can determine the location of the fire occurrence and the subsequent expansion status based on the sensor information detected by the temperature sensor, smoke sensor, etc. provided in each place, the output The unit 13 can output real-time instruction information according to the situation.
For example, in the case where the instruction information is issued relying solely on the information from the disaster information distribution server device 20, there is a possibility that the detection of the occurrence of a fire is delayed and some people are delayed. According to the instruction information providing apparatus 10 of the present embodiment, the occurrence of a fire is quickly detected, and the approach prohibition direction is indicated or the nearest evacuation exit is guided according to the installation position of the instruction information providing apparatus 10. Can be expected to prevent the occurrence of people who are late to escape.

The instruction information providing apparatus 10 can display the disaster information from the disaster information distribution server apparatus 20 together with the instruction information corresponding to the situation determined by the own apparatus.
For example, the instruction information providing device 10 has been dispatched from the disaster information distribution server device 20 to the final evacuation site, wide-area information such as a transportation stop or a road being closed due to a fire, or fire fighting. Information such as whether or not can be acquired. Here, even if the instruction information providing apparatus 10 guides the “evacuation exit A” according to the situation of the site based on the sensor information, if the final evacuation place is not guided, a person from the vicinity of the “evacuation exit A” Congestion may occur without moving. The instruction information providing apparatus 10 displays wide-area information together, so that a person can evacuate from the fire site more reliably.

In addition, when communication with the disaster information distribution server device 20 is down, the instruction information providing device 10 determines the fire status based on the temperature sensor 30A and the like and displays the instruction information. The evacuation site information is recorded in the storage unit 16, and the output unit 13 reads out the evacuation site information from the storage unit 16 and outputs the information, so that a person can be guided to the evacuation site.

[In case of flood]
Recently, inundation of underground spaces in urban areas due to heavy rains such as guerrillas and inundation due to flooding of rivers as well as underground have become problems. For these water damages, the occurrence of water damage can be predicted or determined by detecting the water level with the water level sensors 30D to 30E.
For example, if water damage occurs in the building 1 on the ground, first, the water level sensor 30D installed at a lower height detects the water level. The water level sensor 30D transmits the detected water level information to the instruction information providing devices 10A to 10C.
In the instruction information providing apparatus 10 A, the sensor information acquisition unit 11 acquires water level information from the water level sensor 30 D and outputs it to the determination unit 12. For example, when the value of the water level is equal to or greater than a predetermined threshold, the determination unit 12 determines that a flood (inundation) has occurred in the building 1. When the determination unit 12 determines that water damage has occurred, the determination unit 12 outputs the determination result to the output unit 13.
Similarly, also in the instruction information providing apparatus 10B, the determination unit 12 determines that inundation has occurred in the building 1 based on the water level information acquired from the water level sensor 30D. The same applies to the instruction information providing apparatus 10C.
In the instruction information providing apparatus 10A, the output unit 13 determines that “XX: XX has been inundated based on the determination result of the determination unit 12, the installation position of the water level sensor 30D, and the installation position of the own device. It is Xcm. Since it is dangerous outside, please evacuate to the second floor or higher. " The display unit 14 displays this instruction information.
Further, when the instruction information providing device 10D (not shown) is provided on the second floor or higher of the building 1, the determination unit 12 of the instruction information providing device 10D acquires the water level information detected by the water level sensor 30D, and 1F It is determined that water damage has occurred. The output unit 13 then submerges “XX: XX on the first floor of this building based on the determination result of the determination unit 12D, the installation position of the water level sensor 30D (first floor), and the installation position of the own device (second floor). The inundation depth is Xcm. Please do not go down to the first floor. "

As another example, it is assumed that the building 1 is provided in an underground passage. Further, a water level sensor 30D-1 (not shown) is provided on the ground, and the water level sensor 30D-1 can communicate with the instruction information providing apparatuses 10A to 10C. When heavy rain occurs, the water level sensor 30D-1 detects the water level on the ground and transmits the detected water level information to the instruction information providing devices 10A to 10C.
In the instruction information providing apparatus 10A, the sensor information acquisition unit 11 acquires water level information from the water level sensor 30D-1 and outputs the water level information to the determination unit 12. For example, when the value of the water level is equal to or greater than a predetermined threshold, the determination unit 12 predicts that the water accumulated on the ground overflows and is submerged in the underground from an underground entrance or the like. The determination part 12 will output the prediction result to the output part 13, if an underground inundation is predicted.
Based on the prediction result of the determination unit 12A, the installation position of the water level sensor 30D-1 (“ground”), and the installation position of the own device (“underground”), the output unit 13 sets “XX: XX XX has been reached. There is a possibility of inundation underground. Please move to the floor above the second floor. "
In addition, the output unit 13 includes a guide to a safe route that can move to the second floor or higher depending on the installation position of the device itself, and a warning that does not move in the direction that is likely to cause inundation from the ground. Output instruction information. In addition, it is assumed that the guidance to a safe route and the direction in which inundation from the ground easily occurs is recorded in the storage unit 16 according to the installation position of each instruction information providing device 10.

Further, the instruction information providing device 10 acquires rainfall information from the disaster information distribution server device 20, and the determination unit 12 is more prone to flood damage based on the water level information detected by the water level sensor 30D and the rainfall information. You may predict whether it will be enormous. The output unit 13 outputs instruction information according to the prediction of the determination unit 12.
In addition, the instruction information providing apparatus 10 acquires information on the operation status of the transportation facility and the flood damage in the area from the disaster information distribution server apparatus 20, and uses the information as the determination result of the determination unit 12, the installation position of the water level sensor 30D, You may display together with the instruction information based on the installation position etc. of an own apparatus. As a result, it is possible to grasp the situation of flood in a wide area, so there is no danger of evacuating and moving accidentally to a more severely flooded place.

Flood damage may occur abruptly, especially in the case of underground inundation. Therefore, the detection of the occurrence of flooding tends to be delayed only by the information from the disaster information distribution server device 20.
According to the present embodiment, since the determination unit 12 can predict or determine the occurrence of flood damage based on sensor information detected by a water level sensor, a submergence sensor, or the like provided in various places, the output unit 13 Can output real-time instruction information according to the flood situation. Moreover, since the direction which can be evacuated safely can be shown according to the installation position of the instruction | indication information provision apparatus 10, it can anticipate that generation | occurrence | production of the person who escapes late is prevented.

Further, as another example of a disaster, use in a scene where instruction information is displayed by detecting collapse or destruction of a building or a wall where the sensor 30 is installed can be considered.
For example, (i) a gyro sensor is provided at the position of the wall 30 A, 30 B, 30 C on the wall of the building 1, and the gyro sensor provided at the position 30 A is greater than a predetermined value and greater than a predetermined threshold from the vertical direction to the ground. When the inclination is detected and no inclination is detected from the gyro sensors provided at the

positions

30B and 30C, or (ii) vibration sensors are provided at the

positions

30A, 30B, and 30C on the wall surface of the building 1, and the reference numeral 30A When the vibration that is equal to or greater than a predetermined threshold value at which the wall is broken is detected only from the vibration sensor attached to the position, the determination unit 12 of the instruction information providing apparatus 10C determines that the wall near the reference numeral 30A is broken. Then, the output unit 13 of the apparatus 10C determines that the wall near XXX is destroyed in XX: XX based on the determination result of the determination unit 12, the installation position of the gyro sensor (“30A”), and the installation position of the own apparatus. "Please do not approach the XXX direction" is output.
In another example, a gyro sensor or a vibration sensor is installed on the floor, and the floor breakage is detected by the tilt or vibration of the floor. Instruction information such as "The floor near XXX has been destroyed. Do not go in the direction of XXX." May be output.
In addition, when the plurality of gyro sensors installed in the building 1 detect an inclination greater than a predetermined threshold, or when the plurality of vibration sensors installed in the building 1 detect vibration greater than the predetermined threshold, the determination unit 12 It may be determined that the wall surface has been destroyed and the building 1 has collapsed in a wider area, and the output unit 13 may output instruction information calling for evacuation from the building 1.

FIG. 5 is a second diagram illustrating a usage example of the instruction information providing apparatus according to the embodiment of the present invention.
FIG. 5 is a cross-sectional view of the building 2 to which the instruction information providing device 10 (10A, 10B) is attached. In the building 2, a room 3 and a room 4 are provided. The room 3 includes an instruction information providing device 10A and an image sensor 30G with an image recognition function. The room 4 includes an instruction information providing device 10B and an image sensor 30I with an image recognition function.
With reference to FIG. 4, another example of processing in which the instruction information providing apparatus 10 determines the situation and outputs the instruction information will be described. Each of the image sensors 30I and 30G can communicate with the instruction

information providing apparatuses

10A and 10B.

[In case of congestion]
Assume that the building 2 is an evacuation site, for example. If the image recognition function of the image sensor 30G is used, the number of people in the image captured by the image sensor 30G can be detected. The same applies to the image sensor 30I. The image sensors 30G and 30I transmit the detected images and the number of people appearing in the images to the instruction information providing devices 10A to 10B.
Here, it is assumed that there are many people evacuating from the disaster in the room 3, and there are not many people in the room 4. In the instruction information providing apparatus 10A, the sensor information acquisition unit 11 acquires the images taken by the image sensors 30G and 30I and the number of people appearing in the images, and outputs the images to the determination unit 12 for each image sensor. In the determination part 12, it will determine with being crowded if the number of people becomes more than a certain value.
More specifically, the determination unit 12 determines that the room 3 is congested based on the number of people detected by the image sensor 30G and the installation position of the image sensor 30G. The determination unit 12 determines that the room 4 is vacant based on the number of people detected by the image sensor 30I and the installation position of the image sensor 30I. Then, the determination unit 12 outputs the determination result to the output unit 13. The instruction information providing apparatus 10B performs the same process.
In the instruction information providing apparatus 10A, the output unit 13 has a phrase “room 4 is vacant” based on the determination result of the determination unit 12, the installation positions of the image sensors 30G and 30I, and the installation position of the own apparatus. A map or the like for guiding the position of the room 4 is output. On the other hand, in the instruction information providing apparatus 10B, the output unit 13 determines that “Room 3 is congested based on the determination result of the determination unit 12, the installation positions of the image sensors 30G and 30I, and the installation position of the own apparatus. The instruction information such as “Guide people from 4 so please pack them from the back.” Is output.
According to the present embodiment, at a station or event venue, similarly, it detects the degree of congestion of a person in real time, displays instruction information to call attention to the occurrence of an accident due to congestion, and guides people in the right direction The instruction information to be displayed can be displayed.

[Evacuation delay]
Assume that the building 2 is, for example, a building near a disaster occurrence place. It is assumed that the instruction information providing apparatuses 10A to 10B display instruction information calling for the occurrence of a disaster and evacuation from the building 2.
It is assumed that the wall surface of the room 3 is collapsed, that a person (reference numeral 100) is left in the room 3, and that all persons have evacuated from the room 4. The image sensors 30G and 30I transmit the detected images and the number of people appearing in the images to the instruction information providing devices 10A to 10B.
The instruction information providing apparatus 10A transmits the sensor information detected by the image sensors 30G and 30I to the disaster information distribution server apparatus 20, and determines that there is a person in the room 3 even though the instruction information calling for evacuation is displayed. , Display the instruction information such as "Contact the Disaster Prevention Center. Please wait for a while". In addition, even when communication with the disaster information distribution server device 20 is down, the instruction information providing device 10 (not shown) installed outside the building 2 that can receive the sensor information of the image sensor 30G is in the room 3 It is determined that there is a person who cannot evacuate based on an image in which a wall of the person is collapsed and a person is left behind, and the direction of the building 2 is indicated on the building 2 based on the determination result and the installation position of the image sensor 30G. There may be a case where there is a person who has escaped and instruction information for requesting contact with a fire department or the like is displayed.

[In the case of guidance to vulnerable people]
When the image recognition function of the image sensor 30G is used, it is possible to detect a person wearing a cane, a person using a wheelchair, or the like in an image captured by the image sensor 30G. The same applies to the image sensor 30I.
For example, it is assumed that a person wearing a cane (traffic weak person) exists in the room 3. The image sensor 30G transmits to the instruction information providing devices 10A to 10B that the weak traffic is shown in the detected image or image.
In the instruction information providing apparatus 10A, the determination unit 12 determines that “the traffic weak is present” based on the sensor information detected by the image sensor 30G. Based on the determination result and the installation position of the image sensor 30G, the output unit 13 displays instruction information for guiding the position of the slope or elevator in the building 2.
According to the present embodiment, it is possible to detect a weak traffic person on a general road and display the same guidance on the instruction information providing device 10 provided near the weak traffic person.

FIG. 6 is a diagram showing an example of a processing flow in one embodiment according to the present invention.
The flow of the instruction information display process of the instruction information providing apparatus 10 will be described with reference to FIG.
As a premise, the storage unit 16 stores the position information of the installation position of the instruction information providing device 10, the identification information of the communicable sensor 30, the sensor type, and the position information of the installation position. Further, the storage unit 16 stores determination criteria and determination results for sensor information acquired from each sensor 30. Further, the storage unit 16 stores instruction information according to the determination result and the installation position of the sensor 30, or instruction information according to the determination result, the installation position of the sensor 30, and the installation position of the own device.

First, the sensor information acquisition unit 11 acquires information (sensor information) detected by the sensor from one or a plurality of sensors 30 through the communication unit 15 at predetermined time intervals (step S11). The sensor information acquisition unit 11 outputs the identification information of the sensor 30 and the acquired sensor information to the determination unit 12.
Next, the determination unit 12 determines the situation based on the acquired sensor information (step S12). Specifically, the determination unit 12 uses the identification information and sensor information of the sensor 30 acquired from the sensor information acquisition unit 11 to acquire the determination result in comparison with the determination criterion stored in the storage unit 16.
For example, the storage unit 16 indicates that the sensor information of the temperature sensor 30 A is “fire occurrence (determination result) if X ° C. or higher (determination criterion)”, and “no fire has occurred if lower than X ° C. (determination criterion). A table defining determination criteria and determination results such as “(determination result)” is stored. The determination unit 12 determines from the identification information of the sensor 30 that the sensor 30 is the temperature sensor 30A. Further, the determination unit 12 determines whether or not a fire has occurred in the vicinity of the temperature sensor 30A based on this table with respect to the sensor information acquired by the temperature sensor 30A. When the determination unit 12 determines that a fire has occurred, the determination unit 12 associates the determination of the occurrence of the fire with the determination time, and records them in the storage unit 16.
Further, for example, when it is determined that a fire has already occurred for the sensor information of the temperature sensor 30A a few minutes ago and the determination is recorded in the storage unit 16, and the determination unit 12 is connected to the temperature sensor 30B. With respect to the sensor information, it is determined that a new fire has occurred in the vicinity of the temperature sensor 30B according to the determination criteria defined in the above table. In that case, for example, the determination unit 12 determines that the fire has spread based on the fact that the installation position of the temperature sensor 30B and the installation position of the temperature sensor 30A are within a predetermined distance.
Further, for example, when it is determined that a fire has already occurred for the sensor information of the temperature sensor 30A tens of minutes ago and the determination is recorded in the storage unit 16, and the determination unit 12 has the temperature sensor 30A. Suppose that it is determined that no fire has occurred in the vicinity of the temperature sensor 30A according to the determination criteria defined in the above table. In this case, for example, the determination unit 12 determines that a fire that has occurred near the temperature sensor 30A has been extinguished.
The determination unit 12 outputs the determination result and the position information of the installation position of the temperature sensor 30 A to the output unit 13. Further, the determination unit 12 outputs the determination result “no abnormality” and the position information of the installation position of the temperature sensor 30A to the output unit 13 when the situation such as a disaster is not determined based on the sensor information of the temperature sensor 30A. To do.

The output unit 13 selects and reads out the instruction information according to the determination result and the installation position of the sensor 30 or the instruction information according to the determination result, the installation position of the sensor 30 and the installation position of the own device from the storage unit 16 ( Step S13).
For example, when the determination unit 12 acquires the determination result “fire occurrence” and the position information of the installation position of the temperature sensor 30A, the output unit 13 adds the information based on the determination result and the installation position of the temperature sensor 30A. Select “A fire has occurred near XXX. Please be careful.” Recorded in association.
The output unit 13 selects the instruction information “Please evacuate in the direction of XXX” recorded in association with these information based on the determination result, the installation position of the temperature sensor 30A, and the installation position of the own device. To do.
Further, when the determination unit 12 acquires the determination result “no abnormality” and the position information of the installation position of the temperature sensor 30A, the instruction information “no abnormality” recorded in association with these information is selected.
The output unit 13 outputs the selected instruction information to the display unit 14. The display unit 14 displays the instruction information acquired from the output unit 13 (step S14).

According to the present embodiment, the instruction information providing apparatus 10 determines in real time a state that changes in the vicinity of the sensor based on information detected by a sensor installed in a communicable range, and the determination result and the sensor The instruction information according to the installation position of the device, or the instruction information according to the determination result, the installation position of the sensor, and the installation position of the own apparatus can be displayed.
