  Embodiments of an environment information calculation apparatus and an environment information display system according to the present invention will be described below with reference to the drawings.

FIG. 1a is a diagram illustrating an overall configuration of an environment information calculation apparatus and an environment information display system according to the present embodiment.
The environmental information calculation apparatus 100 has various sensors including a temperature sensor 106, a humidity sensor 107, an ultraviolet sensor 108, an infrared sensor 109, a noise sensor 110, a wind sensor 111, a particle counter 112, and an ultrasonic sensor 113, and the outside world. Measure information.
The various measured data is sent to the measurement result calculation unit 105, and environmental information of the measurement location is calculated based on a plurality of measurement results.
The calculated environment information is sent to the communication unit 104.

The communication unit 104 receives position information acquired from a global positioning system (hereinafter referred to as GPS; GPS; Global Positioning System) 114.
Receiving the environmental information and the position information, the communication unit 104 transmits the information to the environmental information database 115 existing on the network. The information transmission unit of the communication unit 104 is either a wired or wireless communication unit.
The environment information database 115 receives environment information from a plurality of environment information calculation devices (100, 101, 102) via a network. The environmental information database 115 holds the environmental information and provides the environmental information map 103 by adding it to the map.

  In FIG. 1a, the environment information calculation apparatus is shown as an example including three of 100, 101, and 102. However, it is not a limitation condition of the present invention. There may be more environmental information calculation devices, or any one of them. In one case, the environment information database 115 may be incorporated. Further, even in a plurality of cases, any one of the environment information calculation devices may incorporate the environment information database 115, and other environment information calculation devices may share this.

FIG. 1b shows an example of environmental information and use of various sensors in the present embodiment. The environmental information that can be acquired includes items that can be determined based on the measurement results of multiple sensors, but is not limited to this, it is possible to introduce other sensors, acquire other environmental information, etc. is there.
As an example, specific measurement examples of the sensory temperature and the pollen scattering degree based on the environmental information shown in FIG. 1b are shown in FIGS. 2 and 3, respectively.

First, measurement of the sensory temperature will be described with reference to FIG.
The sensory temperature can be expressed by the Misnar sensory temperature and the Linke sensory temperature, the Misnar sensory temperature M is calculated by (Expression 1), and the Linke sensory temperature L is calculated by (Expression 2).

M = t− (1 / 2.3) × (t−10) × (0.8−h / 100) (Formula 1)
t: Temperature (Celsius), h: Humidity (%)
L = t−4 × SQRT (v) (Formula 2)
t: temperature (Celsius), v: wind speed (m / s)

Misnar sensation temperature M is a sensation temperature calculated based on temperature and humidity, and is an index that can express the heat of heat among the sensation temperatures. On the other hand, the Linke sensation temperature L is a sensation temperature calculated from the temperature and the wind speed, and is an index capable of expressing cold. Therefore, in this embodiment, in order to express the temperature of sensation well, the temperature of sensation is calculated based on the calculation results of the two sensations of temperature.

  First, the humidity measurement result 203 measured by the humidity sensor 200 and the temperature measurement result 204 measured by the temperature sensor 201 are sent to the Misnar sensation temperature calculation unit 206, and the sensation temperature representing the heat of humming is calculated by Equation 1. Next, the temperature measurement result 201 and the wind speed measurement result 205 measured by the wind speed sensor 202 are sent to the Linke sensory temperature calculation unit 207, and the sensory temperature representing the cold is calculated by Equation 2. The above result and the temperature measurement result 204 are input to the sensation temperature calculation unit 208, and an index taking into account coldness and sultry heat is calculated.

  For example, if the temperature measurement result 204 represents a high value such as 30 degrees (Celsius, the same applies hereinafter) or higher, it is considered that the temperature measurement result 208 is not easily affected by the Linke temperature that represents the cold. Is output. Further, when the temperature measurement result 204 shows a low value such as less than 10 degrees, it is considered that the temperature measurement result 204 is not easily affected by the misnal body temperature that represents the heat of heat, so the body temperature calculation unit 208 outputs the link body temperature. When the temperature measurement result 204 is 10 degrees or more and less than 30 degrees, the sensory temperature is calculated by calculating the average value of the Misnar sensory temperature and the Linke sensory temperature, for example.

  Information that cannot be presented only by the panoramic image can be presented by adding the calculated sensory temperature on a map and visualizing it. An example is shown in FIG. FIG. 4 (b) is obtained by adding the result of calculating the sensory temperature to the map, and each region is classified into “hot”, “warm”, “comfortable”, “chilly”, “cold” and the like. Since the specific temperature at the destination is known from the display, the user can take action such as avoiding a hot place.

  Next, regarding the degree of pollen scattering, the amount of pollen can be calculated by a particle counter as described in Patent Document 2. Since pollen is floating in the air, it is conceivable that the manner of scattering changes depending on temperature, humidity, and wind speed. Therefore, as shown in FIG. 3, the pollen amount measurement result 301 measured by the particle counter 300 is corrected by the correction unit 308 based on the temperature measurement result 303, the humidity measurement result 305, and the wind speed measurement result 307. 309 is calculated.

  For example, when the humidity measurement result 305 shows a high value, the pollen amount measurement result 301 is decreased, and when the humidity measurement result 305 shows a low value, it is increased. Further, the pollen amount measurement result 301 is increased when the temperature measurement result 302 is high, and is decreased when the temperature measurement result 302 is low. Similarly, regarding the wind speed measurement result 307, when the wind speed is high, the probability of pollen inflow from other regions increases, so the pollen amount measurement result 301 is increased, and if it is low, the pollen amount measurement result 301 is decreased.

  As shown in FIG. 4 (c) by the above processing, it becomes possible to add the degree of pollen scattering to the map, so that the user can not only select the part where the pollen is not scattered but also the pollen scattering of the destination. If the degree is high, it is possible to implement countermeasures suitable for the stage, such as wearing a mask or putting on pollen prevention goggles.

By combining the measurement results of the plurality of sensors described above, it becomes possible to measure environmental information such as the sensory temperature and pollen scattering degree, and by displaying the measurement results in addition to a map, the panoramic image is presented. It makes it possible to present information that is difficult to express.
In the present embodiment, the measurement result calculation unit is arranged in the environment information calculation device, but the present invention is not limited to this, and the calculation unit may be arranged in the environment information database 115.

Next, a second embodiment of the present invention will be described with reference to FIG.
In order to implement the environmental information display system, it is necessary to acquire detailed information over a wide range by the environmental information calculation device.
Therefore, in this embodiment, in order to measure the environment 507, the environment information is measured by the environment information device-equipped mobile phone (504, 505, 506) in which the environment information calculation device is mounted on a mobile terminal such as a mobile phone. If it is possible to measure environmental information with a mobile terminal, one sensor will measure environmental information in many places, and it is possible to acquire detailed information over a wider range than a fixed measuring device. .

  The measured environment information is transmitted to the environment information database 503 via a wireless / wired network. The environment information database 503 holds a large amount of environment information, adds the environment information to a map, transmits it to a mobile phone 500, a personal computer (hereinafter referred to as a PC) 501, a car navigation system 502, etc., and displays the environment information display. Provide a system to do. By mounting the environmental information calculation device on a mobile terminal such as a mobile phone, it is possible to simultaneously measure and display environmental information. In addition, since it is mounted on a mobile terminal, it is possible to acquire data at various locations, unlike measurement using a fixed terminal.

  FIG. 6 shows an example of a sensor mounting position in a mobile phone equipped with an environmental information calculation device. FIG. 6 (a) is a diagram of the mobile phone viewed from the front, and includes a display unit 600 equipped with a liquid crystal display and the like, and an operation unit 601 equipped with buttons and the like for operating the mobile phone.

  The environmental information calculation apparatus can be equipped with various sensors as shown in FIG. 1b. In the case of a terminal such as a mobile phone, a human contacts the terminal in order to perform an operation. For this reason, since the human body touches the sensor depending on the mounting position of the sensor, there is a case where information on the human body is measured instead of information on the outside world. Therefore, for example, in the case of a temperature sensor, as shown in FIG. 6 (c), when the sensor unit 603 is provided on the back surface of the operation unit 601, the operation unit 601 is held by hand when using a mobile phone. Therefore, the human body covers the sensor unit 603. For this reason, the temperature sensor is affected by body temperature and sometimes measures information different from environmental information in the outside world. Therefore, as shown in FIG. 6 (b), the above problem can be solved by providing the sensor unit 602 at a location such as the back surface of the display unit 600 where it is assumed that there is little contact with the human body when using the mobile phone.

  Further, as shown in FIG. 6 (d), it is conceivable to provide a sensor unit 604 on the side surface of the display unit 600. The particle counter or the like shown in FIG. 1b captures the outside air, irradiates the laser, and identifies the suspended matter in the atmosphere based on the reflectance of the light, so that a cavity is provided on the side surface as shown in FIG. This can be realized by generating an air flow using the heat action of 600 and taking outside air into the side cavity.

  It is also assumed that environmental information is not always acquired. When not in use, the mobile terminal may be placed in an environment that is isolated from the outside, such as a bag. Therefore, external information can be efficiently acquired by acquiring environmental information only when the mobile terminal is used.

According to the mobile phone equipped with the environmental information calculation device, it is possible to efficiently measure a wide range of environmental information with a single measuring device.
In this embodiment, the example in which the environment information calculation device is mounted on the mobile phone has been described. However, the present invention is not limited to this, and the mobile phone may be mounted on another mobile terminal.

Next, a third embodiment of the present invention will be described with reference to FIG.
FIG. 7 is an example of a system that enables environmental information to be acquired by effectively using measurement information of various existing sensors, taking a car as an example.

  The in-vehicle sensor 705 cooperates with a speed sensor 706 for measuring the speed of the car, a temperature sensor 707 for measuring the temperature of the outside air and the inside of the car, an ultrasonic sensor 708 for measuring the distance to an obstacle ahead or behind, and a car navigation system. A gyro sensor 709 that measures the traveling direction of the vehicle, a shock sensor 710 that measures the road surface condition, and the like are mounted.

In view of the fact that the environmental information acquisition according to the present invention uses the measurement results of various sensors as shown in FIG. 1b, the on-board sensor already includes the temperature sensor 707 and the ultrasonic sensor 708, and the measurement result of the sensor. Can be used. In addition, the humidity sensor 712, the ultraviolet sensor 713, and the noise sensor 714 described in FIG. 1b that are not mounted on the above-described vehicle-mounted sensor can be newly added as an additional sensor 711.
Various measured data are collected in the car navigation 704, and environmental information is calculated. The calculated environment information is transmitted to the environment information database 703 via the wireless / wired network, and the environment information map is distributed to the display terminal.

The in-vehicle sensor 705 and the additional sensor 711 can measure the environmental information shown in FIG. 1b. Further, by combining the measurement results of the speed sensor 706, the ultrasonic sensor 708, and the noise sensor 714, for example, the measurement result of the speed sensor 706 is less than a certain speed, the measurement result of the ultrasonic sensor 708 is less than a certain distance, and the noise If the surrounding engine sound or the like is determined by the sensor 714, it becomes possible to determine a traffic jam situation or the like, and it is possible to acquire information not shown in FIG. 1b.
With the above configuration, it is possible to measure environmental information by effectively using an existing measuring apparatus.

Next, a fourth embodiment of the present invention will be described with reference to FIG.
This embodiment relates to indoor use of the above-described environmental information calculation apparatus.

  In the second embodiment, in order to acquire information on the outside world, the mounting position of the sensor unit is provided on the display unit 600 as shown in FIG. 6B so as not to contact the human body. On the other hand, in FIG. 6C, since the operation unit 601 includes the sensor unit 603, information on the human body is measured. That is, the sensor unit 603 can measure human body information.

In this embodiment, the environment information calculation device 804 acquires information on the human body 805 with a configuration like the sensor unit 603, and adjusts the air conditioner 801, heating 802, humidifier 803, and the like according to the measurement result.
For example, if the temperature sensor installed in the environmental information calculation device 804 measures body temperature and the humidity sensor measures sweating, the user 805 can judge whether it is “hot”, “comfortable”, or “cold” for the indoor environment. become. If it is determined as “hot”, the air conditioning 801 adjusts the room temperature, stops the humidifier 803, stops the heating 802, etc., and provides a comfortable environment for the user 805.

In addition, when environmental information when going out is comprehensively judged, for example, when walking in an area where the degree of pollen scattering is high, there is a risk that a large amount of pollen may be brought into the room. Therefore, by increasing the humidity in the room, pollen scattering in the room can be suppressed. Further, when the skin damage is large, the indoor environment can be adjusted in the same manner, and measures such as preventing the skin from drying by increasing the humidity can be performed.
As described above, an indoor environment control system is provided that adjusts the indoor environment by acquiring human body information using the environmental information calculation device and utilizing the human body information and the external environment information experienced by the user.

The human body information is measured by the information calculation device, and the indoor environment is adjusted based on the measurement result. However, each is not limited to individual implementation, and each process may be combined.

  When the first, second, and third embodiments are combined, environmental information measured from different mobile terminals such as mobile phones and car navigation systems can be aggregated and presented to the user. Therefore, by combining the first, second, and third embodiments, it is possible to perform environmental information measurement and display that are more suitable than individual implementations.

Next, the case where the first and fourth embodiments are combined will be described. In the first embodiment, information on the outside world is measured by the environment information calculation device, and in the fourth embodiment, information on the human body is measured by the environment information calculation device. By combining both, it is possible to measure both external information and human body information, for example, when the skin is dry, information such as not to enter the area where the skin is damaged, Indoors, it is possible to increase the humidity and keep the moisture. Moreover, when passing through an area where the degree of pollen scattering is high, the indoor humidity can be increased to prevent pollen scattering indoors.
Therefore, by combining the first and fourth embodiments, it is possible to present information more suitable than individual implementation.

Further, the first, second, third, and fourth embodiments can be implemented in combination. By combining the four examples, environmental information over a wide area can be acquired, and information presentation and indoor environment control taking into account the user's physical condition can be realized.
Therefore, by combining the first, second, third, and fourth embodiments, it is possible to present information that is more suitable than individual implementations.
