Description

  The present invention relates to an air conditioning control system that performs air conditioning control, an air conditioner and an air conditioning control method, a temperature measurement system that measures the temperature of a living room, and a temperature measurement method.

  From the viewpoint of global warming, depletion of energy resources, and cost reduction, reduction of power consumption is a very important issue. An increasing number of air conditioners and lighting devices have a power saving function such as turning off the power when not in use. In the air conditioner, power consumption is large, and thus power saving is particularly important.

  In an air conditioning control system that performs air conditioning control using an air conditioner, for example, the temperature is typically measured by a temperature sensor installed in the air conditioner, and air conditioning control is performed based on the measurement result. However, since the temperature distribution in the living room space is uneven, air conditioning is too effective in some places, and air conditioning is too weak in other places. Such unevenness causes an increase in power consumption.

  Comfortable by installing temperature sensors in each of the multiple areas in the living room, measuring the temperature of each area with each temperature sensor, performing air conditioning control in each area, and making air conditioning without excess or deficiency It is possible to achieve both a good environment and power saving.

  In addition, an air conditioning control system including a plurality of infrared sensors that respectively detect the temperatures of a plurality of areas is disclosed (for example, see Patent Document 1).

Japanese Examined Patent Publication No. 7-088957

  However, in the air conditioning control system described in Patent Document 1, the infrared sensor measures the surface temperature of an object captured in the field of view. For example, if there is a fixture, a floor, or a wall in the field of view of the infrared sensor, the surface temperature of the fixture, floor, or wall is measured. In this case, the surface temperature of fixtures, floors, etc. does not necessarily represent the ambient temperature required for air conditioning control. If the difference between these surface temperatures and the ambient temperature is large, appropriate air conditioning control can be performed. Can not.

  Moreover, if a temperature sensor is installed in each of a plurality of areas of the living room space, it is possible to measure an accurate atmospheric temperature in each area and perform air conditioning control for each area in the air conditioner. However, in this case, electric power supplied to each temperature sensor, electric power required for communication means for transmitting the temperature measured by each temperature sensor and the position of each temperature sensor to the air conditioner is required.

  If the position of the temperature sensor is registered in the air conditioner in advance, the information to be notified is only the temperature. However, in this case, it is necessary to re-register the position of the temperature sensor every time the position of the temperature sensor is changed, so that maintenance and operation costs are required.

  There are individual differences in the environment where you feel comfortable. For example, some people do not want to receive the wind from the air conditioner, while others feel that the temperature is good. Therefore, if the air conditioning control is performed for each person, the comfort level is improved and power saving is realized. However, in the case of an office, for example, even if a plurality of air conditioners are installed, it is very troublesome for the user to adjust the settings of the air conditioner by one person.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an air conditioning control system, an air conditioner, an air conditioning control method, a temperature measurement system, and a temperature measurement that can easily realize optimal area air conditioning control. Is to provide a method.

  In order to achieve the above object, in the air conditioning control system according to the present invention, the visible light imaging means captures a visible light image of the entire living room. The infrared imaging means captures an infrared image of the entire living room space. The position detecting means detects the position of each of the plurality of temperature measurement objects whose relation between the ambient temperature and the surface temperature is known based on the visible light image. The measuring means measures the infrared intensity of the infrared image corresponding to each of the detected positions. The temperature acquisition means acquires the ambient temperature corresponding to each of the measured infrared intensities at a plurality of positions. The control means performs air-conditioning control for each of the plurality of areas of the living room based on the acquired ambient temperatures at the plurality of positions.

  According to this invention, the infrared image and visible light image of the whole living room space are imaged. Based on these images, the positions of a plurality of temperature measurement objects whose relation between the ambient temperature and the surface temperature is known and the ambient ambient temperature are measured. And based on the position and atmospheric temperature which were measured in this way, the air-conditioning control according to area of living room space is performed.

  According to this invention, since the surface temperature of the temperature measurement object and the ambient temperature around it are known, the ambient temperature can be accurately obtained from the infrared image.

  Moreover, according to this invention, it is not necessary to arrange | position a temperature sensor in the area which measures atmospheric temperature. Thereby, power consumption can be reduced and maintenance cost of the temperature sensor is not required.

  In addition, according to the present invention, since air conditioning control is performed while detecting the position of the temperature measurement object, effective air conditioning control by area is possible without having to re-register the position in the air conditioner each time. In addition, maintenance and operation costs are not incurred.

  Moreover, since it is not necessary to connect the cable for supplying electric power to a certain temperature measurement object in living room space, a temperature measurement object can be installed in arbitrary places.

  Further, since the user in the living room space can change the installation position of the temperature measurement object, the user himself can easily change the air conditioning control area.

  From the above, if this invention is used, the power consumption and cost of the air conditioning control can be reduced, and the air conditioning control suitable for each person can be realized, so that the optimum air conditioning control can be easily realized.

  The heat insulating part 22 is formed of a heat insulating material. The heat insulation part 22 is formed so that a contact area with the base part 21 and the air contact part 23 becomes small. By reducing the contact area, heat conduction from the base portion 21 to the air contact portion 23 can be suppressed.

  The air contact portion 23 is made of a material having a small heat capacity and a large heat transfer coefficient with air. Examples of such materials include metals such as copper. By adopting such a material, it is possible to make the surface temperature of the air contact portion 23 as close as possible to the ambient temperature by making the surface temperature of the air contact portion 23 follow the change of the ambient temperature extremely high. As a material of the air contact portion 23, a material having a heat capacity equal to or less than a metal and a heat transfer coefficient with air equal to or more than a metal may be adopted.

  The visible light imaging unit 31 receives visible light and captures a visible light image of the entire living room space 4. The infrared imaging means 32 receives infrared rays and takes an infrared image of the entire living room space 4.

  The visible light image storage unit 33 stores the visible light image captured by the visible light imaging unit 31. The infrared image storage unit 34 stores the infrared image captured by the infrared imaging unit 32.

  In the temperature measurement object database 35, information on the temperature measurement object 2 necessary for extracting the temperature measurement object 2 from the visible light image is registered. The information registered in the temperature measurement object database 35 includes, for example, information such as a template image of the temperature measurement object 2 and a feature amount such as a shape.

  The temperature measurement object detection means 36 refers to the information of the temperature measurement object 2 registered in the temperature measurement object database 35, and the temperature measurement object 2 in the visible light image stored by the visible light image storage means 33. The position of is detected. More specifically, the temperature measurement object detection unit 36 performs pattern matching on the visible light image using a template image or the like registered in the temperature measurement object database 35 and a feature amount, and the temperature measurement object 2 is extracted and its position is specified.

  The visible light image-infrared image correspondence database 37 takes into consideration the difference in imaging position and resolution between the visible light imaging means 31 and the infrared imaging means 32, and the visible light image captured by the visible light imaging means 31; Stored is information regarding the correspondence between each position and the infrared image captured by the infrared imaging means 32.

  In the infrared intensity-atmosphere temperature correspondence database 38, the infrared intensity of the surface of the temperature measurement object 2 and the atmospheric temperature corresponding to the infrared intensity are stored in association with each other. The relationship between the infrared intensity and the ambient temperature corresponding to the infrared intensity has been measured in advance through experiments and is known. Conversely, the temperature measurement object 2 is an object whose relationship between the atmospheric temperature and the surface temperature is known.

  The temperature measurement means 39 as the measurement means and the temperature acquisition means measures the ambient temperature around the temperature measurement object 2 with reference to the visible light image-infrared image correspondence database 37 and the infrared intensity-atmosphere temperature correspondence database 38. .

  More specifically, first, the temperature measurement means 39 refers to the visible light image-infrared image correspondence database 37 and the position of the temperature measurement object 2 in the visible light image detected by the temperature measurement object detection means 36. The position of the infrared image corresponding to is acquired. Subsequently, the temperature measuring unit 39 acquires the infrared intensity (that is, the surface temperature of the temperature measurement object 2) at the position of the acquired infrared image. Further, the temperature measuring means 39 refers to the infrared intensity-atmosphere temperature correspondence database 38 and acquires the ambient temperature corresponding to the infrared intensity acquired from the infrared image.

  The visible light image-air conditioning control area correspondence database 40 stores information in which the area classification in the living room space 4 controlled by the air conditioner 1 is associated with each region of the visible light image.

  For example, the visible light image is divided into four, and the air conditioning control areas respectively corresponding to the divided visible light images are a to d. The area classification is determined by the air outlet of the air conditioner 1 and the movable range of the louver. For example, the area classification can be determined by dividing the air-conditioning control area according to the number of outlets and further dividing the air-conditioning control area at a half of the movable range of the louver.

  The air conditioning control means 41 determines which air conditioning control area corresponds to the position of the temperature measurement target object 2 detected by the temperature measurement target object detection means 36 with reference to the visible light image-air conditioning control area correspondence database 40. To do. The air conditioning control unit 41 generates control conditions such as the wind direction and the air volume of the area-specific wind direction / air volume control unit 12 based on the temperature obtained by the temperature measurement unit 39.

  The control information notification unit 42 notifies the air conditioning apparatus 1 of the control information generated by the air conditioning control unit 41. As communication means between the control information notification means 42 and the air conditioner 1, various communication means such as wired communication, wireless communication, infrared communication, and optical communication can be employed.

  Next, the operation of the air conditioning control system according to the present embodiment will be described with a focus on the flowcharts of FIGS.

(Overall operation of the air conditioning control system 100)
First, the overall operation of the air conditioning control system 100 will be described with reference to FIG.

  As shown in FIG. 5, the air conditioning control system 100 waits until the sampling period elapses (step S1; No).

  When the sampling period has elapsed (step S1; Yes), the air conditioning control system 100 performs a temperature measurement process (step S2). This temperature measurement process is performed by detecting the temperature measurement object 2 installed in the living room space 4.

  Subsequently, in the air conditioning control system 100, air conditioning control is performed based on the measured temperature (step S3). In this air conditioning control, the wind direction and the air volume in one or a plurality of air conditioning control areas in the living room space 4 are determined. In the air conditioning control device 1, the area-specific wind direction / air volume control means 12 adjusts the wind direction and air volume for each air-conditioning control area according to the determined wind direction / air volume.

  Thus, in the air conditioning control system 100, the temperature measurement process (step S2) and the air conditioning control process (step S3) are repeated at a constant sampling period. When the position of the temperature measurement object 2 is changed, the temperature measurement object 2 is detected at the changed position in the next sampling cycle, and the corresponding air conditioning control area is changed.

(Temperature measurement processing)
The temperature measurement process in step S2 will be described in more detail.

  As shown in FIG. 6, in the imaging device 3, the visible light imaging unit 31 captures a visible light image of the entire living room space 4, and the infrared imaging unit 32 captures an infrared image of the entire living room space 4 (steps). S11).

  Subsequently, in the imaging device 3, the visible light image storage unit 33 stores the visible light image, and the infrared image storage unit 34 stores the infrared image (step S12).

  Subsequently, the imaging device 3 uses the information of the temperature measurement object 2 stored in the temperature measurement object database 35 to perform pattern matching on the visible light image stored in the visible light image storage unit 33. By doing so, the position of the temperature measurement object 2 is detected (step S13).

  Subsequently, in the imaging device 3, the temperature measurement unit 39 refers to the visible light image-infrared image correspondence database 37 to acquire the position of the infrared image corresponding to the position of the temperature measurement object 2, and the infrared light at that position. The intensity is detected (step S14).

  Subsequently, the temperature measuring unit 39 acquires the infrared intensity at the detected position, refers to the infrared intensity-atmosphere temperature correspondence database 38, and acquires the atmospheric temperature corresponding to the infrared intensity at the position (step S15). .

(Air conditioning control processing)
Next, the air conditioning control process in step S3 will be described in more detail.

  As shown in FIG. 7, first, in the imaging device 3, the air conditioning control means 41 generates control information of the air conditioner 1 such as the air conditioning control area and the air direction / volume of the air conditioning (step S <b> 21). Subsequently, in the imaging device 3, the control information notification unit 42 notifies the air conditioning device 1 of control information (step S22). The area-specific wind direction / air volume control means 12 constituting the air conditioner 1 adjusts the wind direction / air volume for each air conditioning control area according to the control information received by the control information receiving means 11 (step S23).

  Here, an example of a method for generating control information will be described. The control information includes, in the living room space 4, an air conditioning control area, an air outlet corresponding to the air conditioning control area, a wind direction (louver direction) from the air outlet, an air volume, and the like.

  First, the air conditioning control means 41 refers to the visible light image-air conditioning control area correspondence database 40 and adjusts the air conditioning control area to be adjusted based on the position of the temperature measurement object 2 detected by the temperature measurement object detection means 36. To decide. And the air-conditioning control means 41 determines the blower outlet corresponding to the air-conditioning control area to adjust.

  Subsequently, the air conditioning control means 41 determines the air direction / air volume from the determined outlet based on the ambient temperature around the temperature measurement object 2 measured by the temperature measurement means 39.

  The air direction and air volume in the case of cooling can be determined according to the following policy, for example.

  When the ambient temperature is lower than the indoor target temperature, the louver is not moved to the air conditioning control area. Moreover, when the atmospheric temperature of all the air-conditioning control areas used as the object of the determined outlet is lower than the indoor target temperature, the ventilation to the outlet is stopped.

  Also, when the ambient temperature of all air conditioning control areas corresponding to the determined outlet is higher than the indoor target temperature, the louver to the air conditioning control area is set upward from the direction to the air conditioning control area, and the feet are overcooled. Blow so that there is no.

  Subsequently, the direction and amount of air in the case of heating can be determined according to the following policy, for example.

  When the ambient temperature is higher than the indoor target temperature, the louver is not moved to the air conditioning control area. Moreover, when the atmospheric temperature of all the air-conditioning control areas which become the object of the determined outlet is higher than the indoor target temperature, the ventilation to the outlet is stopped.

  Further, when the ambient temperature is lower than the target temperature in the room, the louver to the air conditioning control area is set downward from the direction to the air conditioning control area, so that air is blown from the floor.

  In addition, when controlling a plurality of air conditioning control areas from one outlet, air blowing is performed for a certain time in a state where the louver direction determined by the above method is directed to each air conditioning control area, and this is performed for each air conditioning control area. You may make it repeat sequentially about. Further, the direction of each louver may be continuously moved between the maximum angle and the minimum angle.

  Further, when a plurality of temperature measurement objects 2 are present in the same air conditioning control area, the air conditioning control means 41, for example, the air direction to the air conditioning control area based on the average of the temperatures of the plurality of temperature measurement objects 2 -You may make it determine an air volume and may use only the temperature of either one for air-conditioning control.

  As described above in detail, according to this embodiment, an infrared image and a visible light image of the entire living room space 4 are captured, and the relationship between the ambient temperature and the surface temperature is known based on these images. The ambient temperature around the plurality of temperature measurement objects 2 is measured. And based on the position of the temperature measurement object 2 measured in this way and its atmospheric temperature, the air direction and the air volume control of the air conditioner 1 are performed for each air conditioning control area in the living room space 4.

  Since the surface temperature of the temperature measurement object 2 and the ambient temperature around it are known, the ambient temperature can be determined with high accuracy from the infrared image. In addition, since the temperature measurement object 2 is formed of a material whose surface temperature and ambient temperature are close to each other, the ambient temperature can be obtained with higher accuracy.

  According to this embodiment, it is not necessary to arrange a plurality of temperature sensors in the living room space 4. As a result, power consumption can be reduced, and sensor maintenance costs are not incurred.

  Moreover, when using a temperature sensor etc., in order to perform the air-conditioning control according to an air-conditioning control area effectively, it is necessary for the air conditioning apparatus 1 to preset the change of the position of a temperature sensor. However, in this embodiment, since the air conditioning control is performed while detecting the position of the temperature measurement object 2, effective air conditioning control by area can be performed without having to register the position in the air conditioner 1 each time. It is possible and there is no maintenance / operation cost.

  Moreover, since it is not necessary to connect the cable for supplying electric power to the temperature measurement object 2 in the living room space 4, the temperature measurement object 2 can be installed in arbitrary places.

  For example, since the user of the living room space 4 can change the installation position of the temperature measurement object 2, the user himself can easily change the air conditioning control area.

  From the above, according to this embodiment, the power consumption and cost of the air conditioning control can be reduced, and the air conditioning control suitable for each person can be performed, so that the optimum air conditioning control can be easily realized.

  Moreover, in this embodiment, the position of the temperature measurement object 2 is detected from the visible light image, and the surface temperature of the temperature measurement object 2 is detected from the infrared image based on the position, and the ambient temperature around it. Is acquired. At this time, by referring to the visible light image-infrared image correspondence database 37, the positional error between the visible light image and the infrared image is eliminated. In this way, the position of the temperature measurement object 2 and the ambient temperature in the vicinity thereof can be measured with higher accuracy.

  Further, by associating the installation location of the temperature measurement object 2 with the air conditioning control area, a plurality of areas in the living room space 4 can be individually controlled by one sensor (imaging device 3).

  In addition, by associating the installation location of the temperature measurement object 2 with the air conditioning control area, the air conditioning control can be adjusted only for the air conditioning control area that needs to be adjusted among the plurality of air conditioning control areas. it can.

  In this embodiment, the air-conditioning control system 100 includes one air conditioner 1, one or a plurality of temperature measurement objects 2, and one imaging device 3. However, as shown in FIG. 8, the air conditioner 1, the temperature measurement object 2, and the imaging device 3 may each be one or more than one.

  The shape of the temperature measurement object 2 is not limited to that shown in FIG. As shown in FIG. 9, the temperature measurement object 2 may be such that the air contact part 23 is suspended from the ceiling 204 of the living room space 4 via the string-like heat insulating part 22.

(Attribute information)
Moreover, in the said Embodiment 1, the temperature measurement target object 2 was used only for position detection (namely, determination of an air-conditioning control area) and temperature measurement. However, the attribute information (color, shape, character, etc.) of the temperature measurement object 2 may be detected by image processing or the like and used for air conditioning control.

  In this case, as shown in FIG. 10, the imaging device 3 is an attribute information database in which the relationship between the attribute information of the temperature measurement object 2 and the control information (such as increasing cooling or decreasing heating) is registered. 43 is provided. The temperature measurement object detection means 36 of the imaging device 3 detects the attribute information of the temperature measurement object 2 from the visible light image by image processing or the like. Further, the air conditioning control means 41 refers to the attribute information database 43 and acquires control information corresponding to the attribute information. The control information notification unit 42 notifies the air conditioning apparatus 1 of the obtained control information.

  For example, when the attribute information of the temperature measurement object 2 indicates that the color is red, the cooling of the temperature measurement object 2 is strengthened, or when the shape of the temperature measurement object 2 is a square, the air conditioning apparatus 1 blows air. If the temperature measurement object 2 is not touched or if a temperature (for example, 25 ° C.) is displayed on the outer surface of the temperature measurement object 2, the temperature of the temperature measurement object 2 becomes the temperature. Air conditioning may be controlled.

  Thus, by using the attribute information of the temperature measurement object 2 for air conditioning control, the air conditioner 1 can be controlled based on information other than temperature. Thereby, the user himself / herself can easily control the air conditioning apparatus 1 by changing the attribute information of the temperature measurement object 2.

(Specific usage example)
Next, a specific usage example of the air conditioning control system 100 according to this embodiment will be described. Here, the case where the air conditioning control system 100 is applied to an office, the case where it is applied to a nameplate, the case where it is applied to a pull switch, and the case where it is applied to a monitoring camera such as a department store will be described separately.

(office)
First, a case where the air conditioning control system 100 is applied to an office in which a plurality of desks are arranged in a large space will be described.

  When the air-conditioning control system 100 is used in an office, as shown in FIG. 1, the imaging device 3 is installed on the ceiling of the living room space 4, and the temperature measurement object 2 is installed on each desk. Individuals who use the system are subject to air conditioning control. In this way, air conditioning control suitable for each person is possible. Further, since the air conditioning control area can be changed simply by changing the position of the temperature measurement object 2, the layout and maintenance of the office are facilitated.

  Further, as described above, when air conditioning control is performed based on attribute information, finer control is possible. For example, change the attribute information of the temperature measurement object 2 according to personal preference (for example, change the color of the temperature measurement object 2 to red) so that the wind does not hit or the person who leaves the seat measures the temperature. The attribute information of the target object 2 can be changed (for example, the color of the temperature measurement target object 2 is set to blue) so that the air conditioning control is not performed.

  Usually, in an office, it is difficult for a user to adjust the air conditioning control. However, if this air-conditioning control system 100 is used, the user can easily adjust the air-conditioning control simply by changing the attribute information of the temperature measurement object 2.

(Nameplate)
If the temperature measurement object 2 is attached to a name plate carried by the user, air conditioning control suitable for the individual can be performed. In this way, the user can easily adjust the air-conditioning control simply by changing the attribute information attached to the name plate or the like.

(Pull switch)
When the pull switch is suspended from each of the lights installed on the ceiling, the imaging device 3 is installed on the ceiling, and the temperature measurement object 2 is attached to the tip of the pull switch suspended from the ceiling. Thus, air conditioning control can be performed using the equipment of the living room space 4.

(Surveillance camera)
In department stores where surveillance cameras are already installed, if the surveillance camera is equipped with the function of the imaging device 3 and the temperature measurement object 2 is attached to a product shelf, wall, etc., the existing equipment of the department store is used. Air conditioning control can be performed.

However, in this embodiment, a desk or document that is normally placed in the living room space 4 is the temperature measurement object 2. That is, in this embodiment, the temperature measurement object 2 is an object that is normally installed in the living room space 4.

  This embodiment will be described with reference to FIGS. 11 and 12. FIG. The air conditioning control system 100 according to this embodiment is different from that of the first embodiment in that one imaging device 3B shown in FIG.

  In this embodiment, desks, chairs, documents, name plates, etc. in the living room space 4 are detected as the temperature measurement object 2 and the ambient temperature is measured.

  As shown in FIG. 11, the imaging device 3B according to this embodiment includes a temperature measurement object database 35B, a temperature measurement object detection means 36B, an infrared intensity-atmosphere temperature correspondence database 38B, a visible light image-air conditioning. The point provided with the control area corresponding | compatible database 40B and the air-conditioning control means 41B differs from the imaging device 3 which concerns on the said Embodiment 1. FIG.

(Detection of temperature measurement object)
Information necessary for pattern matching and selection of the temperature measurement object 2 is stored in the temperature measurement object database 35B. For example, information such as a feature amount indicating a template image or shape such as a desk, chair, or document, an imaging time when the template image is captured, and the number of detections detected as the temperature measurement object 2 are stored.

  First, the temperature measurement object detection unit 36B uses the information stored in the temperature measurement object database 35B to select a candidate for the temperature measurement object 2 from the visible light image stored in the visible light image storage unit 33. Extract and detect its position.

  Furthermore, the temperature measurement object detection unit 36B has one temperature measurement object in each of the air conditioning control areas indicated in the visible light image-air conditioning control area correspondence database 40B from the extracted candidates for the temperature measurement object 2. 2 is selected.

  In the infrared intensity-atmosphere temperature correspondence database 38B, for example, the infrared intensity of the temperature measurement object 2 such as a desk, a chair, or a document and the atmospheric temperature corresponding to the infrared intensity are stored. The relationship between the infrared intensity and the ambient temperature corresponding to the infrared intensity is measured and held in advance through experiments or the like.

  The visible light image-air conditioning control area correspondence database 40B stores information in which an area classification controlled by the air conditioning apparatus 1 and a visible light image are associated with each other. For example, the visible light image is divided into four, and each is defined as an air conditioning control area a to d.

  The air conditioning control means 41B generates control conditions for air conditioning control in each air conditioning control area based on the ambient temperature around the temperature measurement object 2 detected by the temperature measurement object detection means 36B.

  Next, the operation of the air conditioning control system 100 according to the present embodiment will be described with a focus on the flowchart of FIG. As shown in FIG. 5, the air conditioning control system 100 according to this embodiment also repeats the temperature measurement process (step S2) and the air conditioning control process (step S3) at a constant cycle (step S1; Yes).

(Temperature measurement processing)
FIG. 12 shows a flowchart of the temperature measurement process according to this embodiment.

  As shown in FIG. 12, in the imaging device 3B, the visible light imaging unit 31 captures a visible light image of the entire living room space 4, and the infrared imaging unit 32 captures an infrared image of the entire living room space 4 (step). S11).

  Subsequently, the visible light image storage unit 33 stores the visible light image, and the infrared image storage unit 34 stores the infrared image (step S12).

  Subsequently, the temperature measurement object detection unit 36B uses the information stored in the temperature measurement object database 35B, and the temperature measurement object 2 candidate and its candidate from the visible light image stored in the visible light image storage unit 33 The position is extracted by image processing or the like (step S16).

  Subsequently, the temperature measurement object detection unit 36B has, for example, a detection temperature candidate 2 having a large number of detections or a color close to black (that is, the infrared radiation tends to be strong) from the detected temperature measurement object 2 candidates. Is selected as the temperature measurement object 2 in each air conditioning control area (step S17).

  Subsequently, in the imaging device 3B, the temperature measurement unit 39 refers to the visible light image-infrared image correspondence database 37 to detect the infrared intensity of the infrared image corresponding to the position of the selected temperature measurement object 2 ( Step S14).

  Subsequently, the temperature measuring means 39 acquires the infrared intensity at the detected position, refers to the infrared intensity-atmosphere temperature correspondence database 38B, and acquires the atmospheric temperature corresponding to the infrared intensity at that position (step S15). .

  The air conditioning control process in step S3 is the same as that in the first embodiment (see FIG. 7).

  As described above in detail, according to this embodiment, an object that normally exists in the living room space 4 such as a desk, a chair, or a document is extracted as a candidate for the temperature measurement object 2 and the extracted temperature measurement is performed. The temperature measurement object 2 was selected from the candidates for the object 2 for each air conditioning control area. As described above, since the object that normally exists in the living room space 4 is the temperature measurement object, it is not necessary to prepare the temperature measurement object. For this reason, it becomes advantageous in terms of cost.

  But you may use the temperature measurement target object 2 which concerns on the said Embodiment 1 as a temperature measurement target object which concerns on this Embodiment.

  Note that the visible light imaging unit 31 and the infrared imaging unit 32 may each capture a visible light image and an infrared image with separate cameras, or capture a visible light image and an infrared image with the same camera. You may do.

  When separate cameras are used, for example, a visible light camera is provided in the visible light imaging means 31 and an infrared camera is provided in the infrared imaging means 32. Then, an infrared image and a visible light image are captured by each camera.

  When the cameras are the same, the visible light image-infrared image correspondence database 37 is not necessary. Further, when the cameras are the same, the camera needs to be a camera that can capture a wide wavelength region from the visible light region to the infrared region. When receiving infrared rays, drive a filter that blocks visible light, and attach the filter to the lens to block visible light. When receiving visible light, drive the filter to drive the filter. May be removed from the lens for imaging.

  In each of the above embodiments, the imaging device 3 includes the visible light image-air conditioning control area correspondence databases 40, 40B and the air conditioning control means 41, 41B. However, the air conditioning apparatus 1 may include the visible light image-air conditioning control area correspondence database 40 and the like, and the air conditioning control means 41 and the like.

  Moreover, in each said embodiment, although the imaging device 3 and the air conditioning apparatus 1 were set apart, as shown in FIG. 13, the air conditioning apparatus 1 has the component of the imaging device 3 built in. Also good. In this case, the control information receiving unit 11 (see FIG. 2) and the control information notifying unit 42 (see FIG. 4) are unnecessary.

  At this time, when a plurality of air conditioners 1 are installed and the imaging device 3 and the air conditioner 1 are not one-to-one correspondence, a means for selecting an air conditioner that selects the air conditioner 1 to be controlled is provided. You may make it prepare. The air conditioner selection means selects the air conditioner 1 to be controlled based on the position of the temperature measurement object 2.

(Application to dehumidification / humidification control)
In the air conditioner 1 in each of the above embodiments, the air-conditioning wind direction and air volume are adjusted for each area. However, dehumidification and humidification may be performed, and the control of air purification is adjusted. May be. In this case, the humidity necessary for controlling dehumidification / humidification is acquired by a hygrometer. A hygrometer is installed indoors, the visible light imaging means 31 images the hygrometer, and the air conditioning control means 41 acquires the hygrometer value, gauge, etc. by image processing or the like. If “perform air cleaning”, “perform dehumidification” or the like is set as control information associated with the attribute information described above, dehumidification, humidification, and air purification can be controlled.

(Application to fire detection)
Further, fire detection may be performed using the captured visible light image and infrared image. For example, when a flame is detected as a temperature measurement object 2 from a visible light image by image processing, and a high temperature region similar to the flame is detected from the same region, a stop signal is transmitted to the air conditioner 1. Or sound an alarm.

  If it carries out as mentioned above, this air-conditioning control system 100 can be applied also to disaster countermeasures.

  In addition, about the temperature measurement target object 2, in order to make it easy to detect, it can be set as a structure as shown in FIG. As shown in FIG. 14, a measurement object 50 is formed of a material having a small heat capacity and a surface temperature close to the ambient temperature, and a material having a large heat capacity and a large difference from the ambient temperature around the measurement object 50. The coating 51 is applied. In this case, the coating 51 can be detected from the infrared image, and the ambient temperature can be measured based on the infrared intensity of the measurement object 50. In this way, the position of the temperature measurement object 2 can also be specified from the infrared image and collated with the position of the temperature measurement object 2 obtained from the visible light image.

  The present invention is suitable for air conditioning control of a living room space.
