Embodiment 1
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an environmental load amount calculation apparatus 101 according to the present embodiment. The environmental load amount calculation apparatus 101 described in the first embodiment includes a position information acquisition unit 102, a measurement unit 103, a climate information acquisition unit 104, an environmental load coefficient database 105 as an environmental load coefficient storage unit, and an environment And a load amount calculation unit 106.

  The position information acquisition unit 102 acquires the current location. The measurement unit 103 measures any one or more of temperature, humidity, and illuminance.

  The climate information acquisition unit 104 acquires information about the climate. The environmental load coefficient database 105 stores an environmental load coefficient for calculating an environmental load that is a load applied to the environment based on the difference between the measurement result of the measurement unit and the climate information.

  The environmental load amount calculation unit 106 calculates an environmental load amount that is a load amount given to the environment based on the measurement result, the climate information of the current location, and the environmental load coefficient.

  As a result, the environmental load amount calculation apparatus according to the present embodiment can calculate the environmental load amount of the place by itself.

  The environmental load amount calculation apparatus 101 according to the present embodiment will be described in more detail. FIG. 2 is a diagram illustrating the environmental load amount calculation apparatus 101 in detail. The environmental load calculation device 101 includes a position information acquisition unit 102, a measurement unit 103, a climate information acquisition unit 104, an environmental load coefficient database 105, and an environmental load calculation unit 106. The climate information acquisition unit 104 Has a climate information database 107 and a communication unit 108. And it has the time information acquisition part 109, the environmental load amount operation part 110, and the display part 111. FIG.

  The position information acquisition unit 102 acquires the position information of the environmental load amount calculation device 101 at the time of reading when the environmental load amount calculation unit 106 reads the position information from the position information acquisition unit 102. Specifically, it is configured with a function capable of acquiring position information such as a GPS (Global Positioning System) receiver. In the present embodiment, a signal transmitted by the GPS satellite as position information is received from a plurality of GPS (Global Positioning System) satellites, and the current latitude, longitude, etc. are calculated based on the received signal. As the position information acquisition unit 102, a function using GPS is used. However, since it is only necessary to acquire position information indicating the current position, a PHS function, a wireless LAN function, or the like may be used. In addition, the position information acquisition unit 102 sets a time for acquiring the position information in advance, and if it takes more time, the position acquisition process is stopped and the process for acquiring the previous position information is performed. The position information at the time of performing may be the current position information.

  The measurement unit 103 measures temperature, humidity, and illuminance. Specifically, the measurement unit 103 includes sensors that can be acquired, such as a temperature sensor, a humidity sensor, and an illuminance sensor. Since the sensor portion as the measurement unit 103 needs to be exposed to the outside air, it should be installed outside the apparatus housing or installed at a position away from the environmental load amount calculation apparatus 101 main body. The device main body may be connected by wire or wireless. Here, for example, when the environmental load display device 101 according to the present embodiment is applied as a function of a mobile phone or the like, it is predicted that the main device is held in a portion close to the body of the user who is the user. The In such a case, for example, even if the temperature or the like is measured, there is a possibility that the environment of the location where the user is present cannot be measured correctly due to the influence of the user's body temperature. May be installed at a position distant from the main apparatus and communicate with the main apparatus using wireless communication or wired communication.

  Furthermore, the measurement unit 103 may include one or more of an infrared sensor and an ultrasonic sensor. Thereby, when the user is in a certain space, the size of the space can be measured by an infrared sensor or an ultrasonic sensor. Thereby, the environmental load coefficient may be changed according to the size of the space, so that a more exact environmental load amount can be calculated.

  As for the illuminance, an image sensor may be used instead of the illuminance sensor. By using an image sensor, it is possible to determine whether the light is fluorescent light or solar light. Therefore, when it is determined that the light is from a fluorescent lamp, the power consumption due to the use of the fluorescent lamp can be calculated as the environmental load, and the environmental load can be calculated more accurately.

In the present embodiment, the measurement unit 103 acquires temperature, humidity, and illuminance, but besides these, gas concentration such as CO ₂ concentration, black smoke particles, pollen, dust, volatile organic compounds ( VOC (volatile organic compounds) and atmospheric pressure may be acquired and output to the display unit 401 and displayed simultaneously with the environmental load. In this case, for example, the CO ₂ concentration may be displayed as a graph. Moreover, by measuring the atmospheric pressure, the environmental load coefficient related to the atmospheric pressure difference is stored in the environmental load coefficient database 105 so that the operating status of the air conditioner is estimated from the atmospheric pressure difference between the outdoor and the indoor. It may be calculated and displayed on the display unit 111.

  The climate information acquisition unit 104 includes one or both of a climate information database 107 and a communication unit 108 that store climate information. In the present embodiment, it is assumed that climate information is acquired using the climate information database 107. Here, the climate information database 107 stores the climate information associated with each position. Specifically, the climate information corresponds to date / time information, position information, and weather information for the past one year of weather statistical information released by a public institution. FIG. 3 is a diagram illustrating an example of climate information. The climate information database 107 holds time information, position information such as latitude, longitude, and address, and climate information such as temperature and humidity for one year nationwide. FIG. 3 shows the climate information of Nara City, Nara Prefecture, on August 11, 2008. The time information at the time of displaying the environmental load is at 11 o'clock on August 11, 2009, and the location information is Nara, Nara Prefecture. If it is near the city, the climate information of temperature 32.4 degrees and humidity 60% will be read. Note that the date and time of the month and the position information are not necessarily the same, and the time information may be read in units of one hour, and the position information may be read as the closest position information.

  Here, the climate information database 107 will be further described. In the present embodiment, the climate information database 107 includes information that associates information on the climate for the past year, date, and position information. Here, the climate information database 107 may further include atmospheric pressure information as the climate information. Moreover, you may make it have weather information (sunny, cloudy, rainy) as climate information. Climate information may vary greatly depending on the weather (clear, cloudy, rainy), etc., even at the same date and time last year. Therefore, for example, the climate information database 107 may include average weather information obtained by averaging information such as temperature and humidity every week (for example, the first week of September) every hour. Thereby, the shift | offset | difference of the present climate information and the climate information which the climate information database 107 has can be made small. In addition, when the weather is different, the difference between the past climate information and the current climate information becomes larger, so as more detailed information, for example, average weather information on a sunny day and a cloudy day in a week. And the average weather information in the case of rainy weather may be included as the weather information of the week of the month. Thereby, even in a season in which the temperature difference between the weather and the weather is severe, the difference between the current climate information and the climate information held in the climate information database 107 can be reduced. Moreover, you may make it have both the climate information for every date and time and the climate information corresponding to the weather in this way. As a result, when calculating the environmental load, the weather information corresponding to the weather is used when the outdoor weather is known, and the average weather information for one week is used when the outdoor weather is unknown. it can. The climate information database 107 is specifically composed of an HDD, RAM, and ROM in the apparatus.

  In the present embodiment, the climate information is acquired from the climate information database 107. However, instead of the climate information database 107, the communication unit 108 may be used to acquire current climate information via the network. Good. Further, the climate information acquisition unit 104 may include both the climate information database 107 and the communication unit 108.

  Specifically, the communication unit 108 is connected to a network such as the Internet, and obtains weather information by communicating with the outside through, for example, accessing the HP that discloses weather information and the like. To do. In this case, by acquiring the current climate information using the communication unit 108, more accurate climate information can be acquired, and the environmental load can be calculated more accurately.

  The environmental load coefficient database 105 stores environmental load coefficients. Here, the environmental load coefficient is a value set based on the difference between the temperature, humidity, and illuminance of the climate information and the temperature, humidity, and illuminance of the measured value, and the difference is the amount of environmental load. It is a coefficient for converting to. In the present embodiment, the environmental load coefficient converts the environmental load amount into the carbon dioxide emission amount. FIG. 4 is a table showing an environmental load coefficient based on the temperature difference for converting the temperature difference between the indoor temperature and the outdoor temperature into the carbon dioxide emission amount. FIG. 5 is a table showing an environmental load coefficient based on the humidity difference for converting the humidity difference between the indoor humidity and the outdoor humidity into a carbon dioxide emission amount. And FIG. 6 is a table | surface which shows the environmental load coefficient for converting the illumination intensity difference of indoor illumination intensity and outdoor illumination intensity into a carbon dioxide discharge amount. Further, when the measurement unit 103 measures the atmospheric pressure, the environmental load coefficient database 105 may have an environmental load coefficient set based on the difference between the atmospheric pressure measured by the measurement unit 103 and the atmospheric pressure of the climate information. . The environmental load coefficient database 105 includes an HDD, RAM, and ROM in the apparatus.

Here, a method for calculating the environmental load coefficient will be described. For example, the power consumption per hour of a general household air conditioner is assumed to be 2.2 (kWh). The CO ₂ emission amount when the power consumption is 1 (kWh) is 0.373 kg. Therefore, the CO ₂ emission amount when the air conditioner is fully operated for 1 hour is 0.373 (kg) × 2.2 (kW) = 0.8206 (kg). For example, when used for 9 hours, 0.8206 (kg) × 9 (h) = 7.3854 (kg).

In the present embodiment, in the case of the environmental load coefficient based on the temperature difference in FIG. 4, as an example, the coefficient from 1 degree difference to 15 degree difference when the air conditioner is operated for 9 hours is obtained. When the temperature difference is small, the power consumption of the air conditioner is considered to be small. Therefore, in the present embodiment, assuming that the air conditioner is fully operated when there is a difference of 15 degrees, the discharge amount obtained by dividing the CO2 emission amount at the time of full operation for 9 hours into 15 equal parts is set as the difference amount of 1 degree difference. Therefore, if the difference is 1 degree,
(7.3854 ÷ 15) × 1 = 0.49236≈0.5 (kg)
In the case of a 2 degree difference, 1 (kg), and in the case of a 3 degree difference, 1.5 (kg). Further, in the environmental load coefficient based on the humidity difference shown in FIG. 5, it is assumed that less power is used in the case of the humidity difference, and the environmental load coefficient of the temperature difference is multiplied by 0.8. In addition, the environmental load coefficient based on the difference in illuminance shown in FIG. 6 is also obtained from the relationship between lux (lx) and power consumption, assuming a case where it is used for 9 hours. In addition, the calculation method of these coefficients is an example, Comprising: It does not restrict to this.

  The environmental load amount calculation unit 106 is triggered by an operation of the environmental load amount operation unit 110 or a fixed time (every hour, every five minutes, etc.), and each acquisition unit (time information acquisition unit 109, position information acquisition unit 102, measurement Various information (time information, position information, and measurement results) is acquired from the unit 103 and the environmental load coefficient database 105). And the climate information (temperature, humidity, illuminance) of the same or the nearest position obtained from the climate information database 107 or the communication part 108 of the climate information acquisition part 104 is acquired, and the difference of climate information is calculated, respectively. Then, the environmental load coefficient obtained from the environmental load coefficient database 105 is integrated with respect to the difference, and the integrated environmental load amount is output to the display unit 111. Here, when the environmental load coefficient database 105 has atmospheric pressure information, the environmental load amount calculation unit 106 determines the difference between the atmospheric pressure measured by the measurement unit 103 and the atmospheric pressure of the climate information database 107, and the environmental load coefficient based on the atmospheric pressure. And the environmental load amount may be calculated.

  The time information acquisition unit 109 has a function of acquiring the time at the time of reading by performing reading and a function of setting the time of writing by performing writing. The time information acquisition unit 109 includes a reference clock generation unit (not shown) and a clock circuit (not shown) that performs a timing operation in synchronization with a clock generated from the reference clock generation unit.

  The environmental load amount operation unit 110 is an operation interface for displaying the environmental load amount, powering the apparatus, setting time information, updating various databases, and calibrating position information, and includes a switch and a touch panel.

  The display unit 111 displays the environmental load amount calculated by the environmental load amount calculation unit 106. Specifically, it is composed of an LCD (Liquid Crystal Display). FIG. 7 is a diagram illustrating an example of a display of the environmental load amount displayed on the display unit 111. The current location is displayed in the upper row, and the graph showing the carbon dioxide emissions as the environmental load is displayed in the lower row. The graph shows that there is more environmental load as it extends to the right. In the present embodiment, the current carbon dioxide emission is 1.8 (kg), the carbon dioxide emission due to the temperature difference between the climate information and the measured value is 0.8 (kg), and the carbon dioxide emission due to the humidity difference The amount is 0.4 (kg), and the carbon dioxide emission due to the difference in illuminance is 0.6 (kg). The display format may be such that each environmental load amount is individually displayed as in the present embodiment, or each environmental load amount may be added and displayed. Furthermore, an address obtained from position information may be displayed as the current location. Furthermore, when the measurement unit 103 has a function of measuring gas concentration, black smoke particles, pollen, dust, and volatile organic compounds (VOC), the acquired measurement value is calculated together with the calculated environmental load. You may make it display.

  In the present embodiment, time information, position information, and climate information are acquired, compared with outdoor climate information, and the environmental load is calculated and displayed. It can be displayed easily.

  Next, the operation up to the display of the environmental load will be described. FIG. 8 is a flowchart showing the operation of the environmental load amount calculation apparatus 101 according to this embodiment. The calculation of the environmental load amount is started when an instruction to display the environmental load amount is input via the environmental load amount operation unit 110, or triggered by a fixed time (every hour or every five minutes).

  First, various information is acquired (step S201). In the various information acquisition 201, time information is acquired from the time information acquisition unit 109, position information is acquired from the position information acquisition unit 102, and measurement results are acquired from the measurement unit 103. Regarding the acquisition of location information, even if you try to acquire it indoors, it may not be acquired normally, so if you set a time in advance and you cannot acquire location information normally even after the time has passed, Use location information. The measurement unit 103 acquires temperature, humidity, and illuminance.

  Next, the climate information is read (step S202). In step S202, climate information is read from the climate information database 107. In the present embodiment, the climate information to be read is filtered by time information and position information, and the climate information that is the same month date and time and the same position information is read.

  Next, climate information is compared (step S203). In step S203, the climate information obtained by the acquisition 201 of various information and the reading 202 of climate information is compared and a difference is obtained. For example, in the case of temperature, 26 ° C. is obtained in the acquisition 201 of various information, and 30 ° C. is acquired in the reading of the climate information 202, the difference is −4 ° C.

  Next, the environmental load coefficient is read (step S204). In step S204, the environmental load coefficient based on the temperature difference or humidity difference is read from the environmental load coefficient database 105.

  Next, the environmental load amount is calculated (step S205). In step S205, each environmental load coefficient is integrated with respect to the temperature difference and humidity difference obtained in step S203. Regarding illuminance, if position information acquisition timeout has occurred, or if an image sensor is used as the illuminance sensor, if it can be determined that the light is from a fluorescent lamp, it is determined indoors and used as illumination light. Integrate environmental load factors. When the acquisition of the position information is normally completed, it is determined as sunlight, the environmental load coefficient is integrated as 0, and the environmental load as illuminance is set as 0.

  Finally, the environmental load is displayed (step S206). In step S206, each environmental load obtained in step S205 is displayed on the display unit 111. Here is an example when temperature, humidity, and illuminance are acquired. When gas concentration, black smoke particles, pollen, dust, and volatile organic compounds (VOC) are acquired, they are displayed together with the calculated environmental load. You may make it do.

  The environmental load calculation device 101 according to the present embodiment compares the measurement value acquired by the device itself with the climate information held in the device, calculates and displays the environmental load by the environmental load coefficient. As a result, it is possible to calculate and display the amount of environmental load with a single device. Furthermore, when the illumination light other than sunlight is determined by the illuminance sensor, the image sensor, and the position information, the environmental load amount due to the illumination light can be calculated and displayed by the apparatus alone. Furthermore, since the measured value at that location is acquired and the environmental load is calculated and displayed, the amount of environmental load generated to create a comfortable environment at that location can be grasped. Moreover, since the current measured value is acquired and the environmental load is calculated and displayed, a display with high real-time characteristics can be achieved.

Embodiment 2
The environmental load calculation device 101 according to the present embodiment has the same configuration as the environmental load calculation device 101 according to the first embodiment. However, the position information acquisition unit 102 of the environmental load amount calculation apparatus according to the present embodiment is different in that it determines whether the environmental load amount calculation apparatus 101 is currently outdoors but indoors. The environmental load amount calculation apparatus 101 according to this embodiment will be described below.

  As in the first embodiment, the position information acquisition unit 102 of the environmental load amount calculation apparatus 101 according to the present embodiment receives a plurality of position information, identifies the current location based on the plurality of position information, and can receive the position information. Based on the number of pieces of position information, it is determined whether the environmental load calculation device is indoors or outdoors. Specifically, it is configured with a function capable of acquiring position information such as a GPS (Global Positioning System) receiver. In this embodiment, a signal transmitted by the GPS satellite as position information is received from a plurality of GPS (Global Positioning System) satellites, and the current latitude, longitude, etc. are calculated based on the received signal. In this form, it is further determined whether the environmental load calculation apparatus 101 is indoors or outdoors based on the accuracy of the position information, in other words, the number of receivable position information. When positioning based on radio waves received from GPS satellites, four or more signals from GPS satellites must be received. Therefore, in the present embodiment, for example, if the positioning state is possible and the number of satellites is 4 or more, it is determined that the environmental load amount calculation apparatus 101 is outdoors and the rest is indoors. It may be. In addition, for example, for a GPS module as a part for positioning a position using a GPS satellite, information indicating “positioning state” indicating a position detection state such as “positioning is possible” or “positioning is not possible” is output. May be provided to obtain that information. Further, indoor or outdoor may be determined based on the above “positioning state” and the number of satellites of the received signal. Furthermore, when acquiring position information, if normal position information cannot be acquired even after a predetermined time has elapsed, the position information acquisition unit 102 determines that the environmental load amount calculation device 101 is indoors. You may make it judge.

  When the position information acquisition unit 102 determines that the environmental load calculation device 101 is outdoors, the climate information acquisition unit 104 measures outdoor temperature, humidity, illuminance, and the like via the measurement unit 103. Then, the measured value is written as climate information in the climate information database 107.

  FIG. 9 is a flowchart showing the operation of the environmental load amount calculation apparatus 101 according to this embodiment. The operation is the same as that of the first embodiment except that it is determined whether the environmental load amount calculation apparatus 101 is indoors or outdoors and the climate information acquisition unit 104 writes the measurement values of the measurement unit 103 in the climate information database 107. Therefore, the description is omitted.

  After step S201, which is the acquisition of various types of information, the position information acquisition unit 102 makes an indoor determination (step S601). If it is determined to be indoor (step S601: No), climate information is read (step S202).

  If it is determined in step S601 that it is outdoors (step S602), the climate information is written in the climate information database 107 (step S602), and the climate information is written in the climate information database 107. The operations after step S602 are the same as those in the first embodiment.

  Here, regarding the case of determining indoors, not only when the accuracy at the time of position information acquisition is low, but also when a timeout occurs in the process of acquiring position information. In this case, if a time-out occurs in the position information acquisition, it is determined that the user has moved indoors. Furthermore, when the difference with the temperature acquired last time is large (for example, when there is a difference of 5 ° C. or more), or when the difference with the previously acquired pressure is large, it may be determined that the vehicle has moved to the outdoors. Furthermore, when the accuracy at the time of position information acquisition is low by combining these determination methods, the difference between the temperature difference acquired last time and the currently measured temperature is obtained, and there is a difference equal to or greater than a predetermined threshold. In this case, it may be determined that the user has moved indoors. The operation after being determined to be outdoors is the same as in the above embodiment.

  As a result, it is not necessary to hold all the weather statistics information released by public institutions, and the capacity of the climate information database can be reduced. In addition, since the actually measured outside air temperature is used, there is an effect that it is possible to obtain data with higher accuracy than weather statistical information published by a public institution.

Embodiment 3
A car navigation system according to the present embodiment will be described. FIG. 10 is a diagram showing a car navigation system 701 according to the present embodiment. The car navigation system 701 is obtained by adding a function for calculating an environmental load to a general car navigation system. In the present embodiment, the environmental load is calculated from the amount of gasoline used.

  The car navigation system 701 includes a position information acquisition unit 102, a measurement unit 103, a climate information acquisition unit 104, an environmental load coefficient database 105, an environmental load calculation unit 106, a time information acquisition unit 109, and an environmental load. It has an operation unit 110 and a display unit 111, and further includes a fuel acquisition unit 702, a travel distance acquisition unit 703, and an in-vehicle measurement unit 704.

  The fuel acquisition unit 702 acquires the amount of gasoline used by the car on which the car navigation system 701 is mounted. The travel distance acquisition unit 703 acquires a travel distance. The on-vehicle measuring unit 704 indicates an in-vehicle temperature sensor and humidity sensor mounted on the automobile. Here, when the fuel acquisition unit 702 is an automobile equipped with an ECU (Engine Control Unit), for example, the fuel acquisition unit 702 acquires a vehicle speed pulse and an injector signal from a connector connected to a wire harness that is a signal line of the ECU. Thus, the amount of fuel used and the travel distance may be acquired. Here, the vehicle speed pulse is a signal that outputs one pulse at a certain distance, and the travel distance acquisition unit 703 acquires the travel distance by detecting and processing the pulse. The injector signal is a signal for instructing fuel injection, and the fuel acquisition unit 702 acquires the amount of fuel used by detecting and processing the waveform.

  Next, the operation up to the display of the environmental load will be described. Since the basic operation is the same as in the first and second embodiments, only different parts will be described. The car navigation system 701 does not have the climate information database 107. Regarding the climate information, since the automobile has an in-vehicle measuring unit 704 in which an in-vehicle temperature sensor and a humidity sensor are mounted, the outside climate information is acquired using these sensors. In addition, the function of the car navigation system 701 is used for time information, position information, environmental load operation, and environmental load display.

  The environmental load coefficient database 105 further includes an environmental load coefficient based on the amount of gasoline used.

  Here, the environmental load amount calculation unit 106 of the car navigation system 701 will be described. The environmental load amount calculation unit 106 acquires information on the environmental load coefficient, vehicle outside temperature, vehicle interior temperature, vehicle exterior humidity, vehicle interior humidity, gasoline usage, and travel distance. Then, the environmental load is calculated from these pieces of information.

  First, the difference between the outside temperature and the inside temperature is taken and integrated with the environmental load coefficient. Similarly, the difference in humidity is taken and integrated with the environmental load coefficient. Furthermore, the amount of gasoline used and the environmental factor are integrated. In the present embodiment, the environmental load due to temperature difference and humidity difference is included in the environmental load due to gasoline usage.

  Thus, in this embodiment, it is possible to calculate and display the environmental load caused by the fuel consumed by the vehicle and the environmental load generated to create a comfortable environment in the vehicle. As a result, it is possible to grasp the amount of environmental load discharged by driving the vehicle and the amount of environmental load for building the environment inside the vehicle.

Embodiment 4
Compared with the environmental load amount calculation apparatus 101 according to the first embodiment, the environmental load amount calculation apparatus 801 according to the present embodiment communicates with other devices as a communication unit for communicating with other environmental load amount calculation apparatuses. Unit 802 and a reliability calculation unit 803 that determines the reliability of the environmental load. FIG. 11 is a diagram showing an environmental load amount calculation device 801 according to the present embodiment.

  The other device communication unit 802 communicates with the nearby environmental load amount calculation device 801 by wireless communication or wired communication. The communication method itself may be any method as long as the communication range is about several tens of meters. The other device communication unit 802 communicates with the other environmental load amount calculation device 801, and the stop time, which is the time during which the other environmental load amount calculation device 801 stays in one place, the measurement result from the current time, An environmental change amount and an environmental load amount, which are values changed in comparison with a measurement value measured before a predetermined time, are acquired.

  The reliability calculation unit 803 compares the value acquired via the environmental load amount calculation device 801 with the stop time and the environmental change amount calculated by the environmental load amount calculation device 801, and the longer the stop time, or Calculated by the environmental load amount calculation device having the smaller change amount of one or more values among the environmental change amounts, or the longer stop time and the smaller change amount of one or more of the environmental change amounts. The environmental load is judged to be less reliable in accordance with the environmental load of the environmental load calculation device that is judged to have higher reliability and the reliability is judged to be higher. Correct the environmental load of the calculation device.

  Here, the reliability will be described. For example, when entering a shopping center, it is assumed that another environmental load calculation device (others) has already stayed in the shopping center for two hours. Since the environmental load calculation device (self) has a short stay time and entered the shopping center from the outside, the environmental information fluctuation amount is large. In this case, the environmental information obtained from the environmental load calculation device (other) has higher reliability and the reliability of its own environmental information is lower. ) Environmental information is more reliable, so the accuracy of the environmental load can be improved.

  Therefore, the reliability calculation unit 803 calculates the reliability from the stop time and the environmental change amount calculated by the environmental load amount calculation device 801, and calculates the calculated reliability and the reliability acquired via the environmental load amount calculation device 801. The environmental load amount is calculated by using the measurement result of the environmental load amount calculation apparatus that has been compared and determined that the obtained reliability is high.

  Next, the operation until the environmental load amount display of the environmental load amount calculation apparatus 801 will be described. Since the basic operation is the same as in the other embodiments, only different parts will be described. The other device communication unit 802 is always in a receiving state, and when there is another environmental load amount calculation device 801 in the vicinity, it receives and holds the environmental load amount and reliability calculated by the environmental load amount calculation device. Keep it.

  The reliability is calculated from the stay time and the variation amount of the climate information. The longer the stay time, the higher the reliability, and the smaller the change amount of the climate information, the higher the value. For example, when staying at the same place for 2 hours and the amount of change in climate information is 1 ° C., the value (2) obtained by dividing the stay time by the amount of change in climate information is set as the reliability.

  Then, when displaying, compare the environmental load amount and reliability of other environmental load amount calculation devices obtained from the communication unit with the environmental load amount and reliability calculated by yourself, and correct according to the higher reliability I do. Thereby, since the environmental load amount is corrected according to the environmental load amount with high reliability, the accuracy of the environmental load amount can be improved.

Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.
