Description

  The present invention relates to an air conditioner that performs operation control according to a person existing in a space.

Conventionally, as an apparatus for performing operation control according to a person existing in a space, for example, as disclosed in Patent Document 1, an air conditioner that performs operation control according to a remote control operation of a person in the space is generally used. Known. Such an air conditioner is configured such that the remote controller sets the desired temperature, humidity, etc., and performs air conditioning based on the setting conditions.
JP 2006-266677 A

  By the way, as described above, in the conventional air conditioner, operation control is performed so that the temperature and humidity are set by operation of a remote controller or the like, and a person sets the temperature so that the temperature and humidity become appropriate. In addition, there is an inconvenience that it is necessary to sequentially input the humidity and humidity.

  The present invention has been made in view of the above points, and an object of the present invention is to provide an air conditioner capable of performing an air conditioning operation suitable for a person in a space without performing an input operation with a remote controller or the like. There is to do.

  In order to achieve the above object, in the air conditioner according to the present invention, focusing on the fact that the blood flow of a person changes depending on the temperature in the space, etc., air conditioning control is performed according to the amount of hemoglobin component in the blood. did.

  Specifically, in the first invention, an air conditioner that performs air conditioning in the space is targeted, and the photographing means (31) for photographing a person existing in the space and the photographing means (31) are used for photographing. An image extraction means (42) for extracting at least a partial region of the human face from the obtained image, and a reflection component by hemoglobin is extracted from the image extracted by the image extraction means (42) to obtain a hemoglobin component amount A hemoglobin detection means (43) for detecting the control signal, a control signal generation means (45) for generating a control signal for air-conditioning operation based on the hemoglobin component amount detected by the hemoglobin detection means (43), and the control signal And an operation control means (48) for performing an air-conditioning operation according to the above.

  With this configuration, it is possible to detect a hemoglobin component amount from a human face image in a space and predict a blood flow rate of the person in the space. Thereby, it is possible to grasp how a person in the space currently feels the temperature and humidity in the space (temperature / cooling sensation). Then, by generating a control signal based on the amount of hemoglobin component, air conditioning control can be performed so that the temperature and humidity become optimum for the person in the space.

  The control signal generation means (45) compares the amount of hemoglobin component detected by the hemoglobin detection means (43) with a preset predetermined value, and generates a control signal based on the comparison result. (Second invention). In this way, by comparing the detected hemoglobin component amount with a predetermined value set in advance and performing air conditioning control according to the result, control of the air conditioning operation can be performed easily and reliably using the detected value of the hemoglobin component amount. It can be performed.

  In particular, the control signal generating means (45) generates a control signal for cooling operation when the amount of the hemoglobin component is equal to or greater than a first predetermined value, and a second signal in which the amount of the hemoglobin component is smaller than the first predetermined value. It is preferable that the control signal for the heating operation is generated when the value is equal to or less than the predetermined value (third invention). Here, the first predetermined value means an amount of a hemoglobin component that a person in the space feels hot and needs to lower the sensible temperature by cooling operation, and the second predetermined value is the first predetermined value. The value is lower than the value, and means the amount of hemoglobin component that a person in the space feels cold and needs to raise the sensible temperature by heating operation.

  Thereby, when the person in the space feels hot, the cooling operation is performed, and when the person feels cold, the heating operation is performed. Therefore, the hemoglobin component amount of the person in the space is the first predetermined amount. The air conditioning is controlled to be between the value and the second predetermined value. Therefore, the temperature and humidity in the space can be made comfortable for the people in the space.

  Here, the predetermined value may be a hemoglobin component amount set corresponding to a predetermined race (fourth invention), and is set to include individual differences in the hemoglobin component amount. (5th invention).

  In this way, by setting the predetermined value corresponding to a predetermined race, it is possible to perform more suitable air conditioning control for races with different skin colors and body temperature. In addition, if the predetermined value is set so as to have a predetermined range in consideration of individual differences, even if there is a variation in blood flow amount or hemoglobin component amount among individuals, or a difference in sensory temperature, it is more accurate. Air conditioning control can be performed.

  Further, the control signal generation means (45), when the hemoglobin component amount detected by the hemoglobin detection means (43) has not changed for a predetermined period after the start of operation, the hemoglobin component amount approaches a specified value. It is preferable that the control signal for changing the set value of the air-conditioning operation is generated as described above (sixth invention).

  Here, the specified value means the amount of hemoglobin component when a person in the space feels comfortable. For example, in the above-described configuration, between the first predetermined value and the second predetermined value. Is equivalent to As described above, if the amount of hemoglobin component does not change, it is determined that the current operating conditions do not affect the thermal sensation so much that the amount of hemoglobin component is close to the comfortable amount. By changing the setting value of the air conditioning operation, it is possible to achieve a temperature / humidity more suitable for people in the space.

  In addition, a personal authentication means (46) for identifying a person existing in the space, and a personal information storage means (individual identification information and correction information for correcting the control signal are stored in association with each other) 47), and the control signal generation means (45) reads the correction information from the personal information storage means (47) according to the individual identified by the personal authentication means (46), A control signal may be generated according to the correction information (seventh invention).

  Thereby, the person who exists in the space can be identified, and the air conditioning operation can be controlled based on the correction information corresponding to each individual. Therefore, more optimal air conditioning control can be performed for each individual.

  The personal information storage means (47) further includes an input means (21) for a person in the space to input settings, and the personal information storage means (47) Assume that the setting input to the input means (21) is stored in association with the correction information (eighth invention).

  Thus, when a person in the space performs an input operation using an input means (21) such as a remote controller, for example, the current thermal sensation of the person can be more accurately grasped from the relationship with the amount of hemoglobin component at that time. By storing the relationship between the hemoglobin component amount and the setting by the input means as correction information, the control signal can be corrected more accurately and accurately. Therefore, when an individual is identified by the personal authentication means (46), the control signal is corrected using the correction information stored in the personal information storage means (47), thereby performing air conditioning control more suitable for the individual. It can be carried out.

  As described above, according to the air conditioner (1) of the present invention, the image of the human face in the space photographed by the photographing means (31) is extracted by the image extracting means (42), and the hemoglobin detecting means is extracted from the image. Since the control signal of the air-conditioning operation is generated based on the amount of the hemoglobin component detected by (43) and the air-conditioning operation is performed according to the control signal, the person in the space does not perform the setting operation with a remote controller or the like. The person's current thermal sensation can be predicted from the quantity, and air conditioning control suitable for the person can be performed. Therefore, troublesome operations such as remote control operations can be eliminated, and air conditioning control can be performed accurately and accurately according to the current temperature / cooling sensation of a person in the space.

  Further, according to the second invention, the control signal is generated based on a comparison result between the detected hemoglobin component amount and a predetermined value set in advance, so that the hemoglobin component amount can be used simply and reliably. Air conditioning operation can be controlled. In particular, according to the third invention, the cooling operation is performed when the detected amount of the hemoglobin component is equal to or greater than the first predetermined value, and the heating operation is performed when the detected amount of the hemoglobin component is equal to or smaller than the second predetermined value. The air conditioning control can be performed so that the amount of the hemoglobin component is comfortable for the person inside. And according to 4th invention, only the hemoglobin component amount can be detected reliably by setting the said predetermined value corresponding to a predetermined race, and optimal air-conditioning control can be performed. Further, according to the fifth invention, by setting the predetermined value so as to include individual differences in the amount of hemoglobin component, the variation in the amount of hemoglobin component due to thermal sensation is taken into account in consideration of variations in the amount of hemoglobin component between individuals. Only changes can be extracted, and more optimal air conditioning control can be performed.

  Further, according to the sixth invention, when the hemoglobin component amount has not changed for a predetermined period, the set value of the air-conditioning operation is changed so that the hemoglobin component amount approaches the specified value. Air-conditioning control can be performed more reliably and effectively so as to achieve a comfortable temperature and humidity.

  According to the seventh invention, the person in the space is identified by the personal authentication means (46), the correction information corresponding to the identified individual is read from the personal information storage means (47), and the correction information is read. Since the control signal is generated according to the control, the control determined based on the amount of hemoglobin component is corrected for each individual, and the optimum air conditioning control for each individual can be performed.

  Further, according to the eighth invention, the setting input by the input means is stored as correction information in association with the amount of hemoglobin component detected at that time, and the control signal is generated using the correction information. Therefore, it is possible to learn the correction information of each individual and perform the air conditioning control most suitable for the individual.

The imaging device (31) is a camera having a general configuration, and may be provided integrally with the air conditioning device (1) or may be provided separately. The image data obtained by the image pickup device (31) is sent to the indoor unit (11) of the air conditioner (1) and subjected to image processing. Then, as will be described in detail later, the amount of hemoglobin component is detected. Used.

  Further, the air conditioner (1) includes a controller (41) that obtains a blood flow from the image data captured by the imaging device (31) and performs air conditioning control based on the blood flow. As shown in FIG. 2, the controller (41) includes an image extraction unit (42) (image extraction means) for extracting a face image from the image data obtained by the imaging device (31), and an extracted image. A hemoglobin detector (43) (hemoglobin extraction means) for detecting the amount of hemoglobin based on the blood flow, a blood flow calculator (44) for calculating a blood flow from the hemoglobin component, and a control signal generated according to the blood flow Control signal generator (45) (control signal generator) for performing personal identification, personal authentication unit (46) (personal authentication unit) for identifying an individual, and personal information storage for storing correction information in association with the personal identification information (47) (Personal information storage means) and an operation control section (48) (operation control means) for performing an air conditioning operation in response to the control signal.

  Specifically, the image extraction unit (42) is configured to extract only the image of the face portion from the image information obtained by the imaging device (31). The image extraction unit (42) may extract the entire face or only a part of the face suitable for detecting the amount of hemoglobin component.

  The hemoglobin detection unit (43) is configured to extract a reflection component due to hemoglobin from the face image extracted by the image extraction unit (42) and obtain a hemoglobin component amount from the reflection component. That is, the hemoglobin detector (43) has a generally well-known configuration in which a color component corresponding to hemoglobin is separated and extracted from an image.

  The blood flow rate calculation unit (44) calculates the blood flow rate from the hemoglobin component amount detected by the hemoglobin detection unit (43) using, for example, the relationship between the average hemoglobin component amount and the blood flow rate of the Japanese. It is configured as follows.

  The personal authentication unit (46) is configured to identify an individual from the face image extracted by the image extraction unit (42). Specifically, the identification information stored in the personal information storage unit (47) is compared with the face image to identify the individual. Note that the personal authentication unit (46) is not limited to identifying an individual from a face image, and may identify an individual from an IC card or voice.

  The personal information storage unit (47) is composed of storage means such as a memory, for example, and is configured to store correction information together with the identification information. This correction information is for correcting the control of the air conditioning operation performed based on the blood flow obtained from the face image in correspondence with each individual. In this embodiment, the blood at the time of switching the air conditioning operation is corrected. It is used to change the flow rate threshold (which will be described in detail later, first and second predetermined values).

  The personal information storage unit (47) is configured to store input information input from the remote controller (21) as the correction information. Specifically, when input information is transmitted from the remote control (21), the imaging device (31), the image extraction unit (42), the hemoglobin detection unit (43), and the blood flow rate calculation unit (44) The hemoglobin component amount and the blood flow rate are obtained from the face image at that time, and stored in the personal information storage unit (47) as correction information together with the input information.

Is configured to output the control signal so that the threshold value is corrected and the driving control suitable for each individual is performed. Further, the control signal generator (45) sets the set temperature (set value) so as to approach an appropriate blood flow rate (specified value) that is comfortable when the blood flow rate does not change even after a predetermined time has elapsed after the start of operation. ). By doing so, it is possible to control the driving so that the temperature is suitable for a person in the space.

  The said operation control part (48) is for actually controlling each component of the said air conditioning apparatus (1) according to the control signal produced | generated by the said control signal production | generation part (45).

-Driving control by face image-
Next, in the air-conditioning apparatus (1) having the above-described configuration, control in the case of performing an air-conditioning operation by obtaining a blood flow rate from a face image will be described using the flow of FIG.

  When the flow of FIG. 3 starts, first, an image of a person in the space is taken by the imaging device (31) (step S1). The photographed image information is sent to the image extraction unit (42), and only the face image is extracted by the image extraction unit (42) (step S2). Then, the hemoglobin detector (43) extracts the reflection component due to hemoglobin from the extracted face image, and measures the color development due to the hemoglobin (step S3). That is, in this step S3, the amount of hemoglobin component can be detected from the face image. Thereafter, the blood flow is calculated based on the detected hemoglobin component amount (step S4). That is, in this step S4, the blood flow rate of the person in the space is calculated from the relationship between the color development by the average Japanese hemoglobin and the blood flow rate.

  In subsequent step S5, personal authentication for identifying each individual is performed. Specifically, each individual is identified by acquiring data for personal authentication and collating it with data stored in the personal information storage unit (47). As a personal authentication method, for example, a face image photographed by the imaging device (31) may be used, or an IC card, voice, or the like may be used. For each individual identified in step S5, a value corresponding to each individual (a value corrected by correction information) is set when setting a predetermined value as a threshold value in step S8 described later. become. In step S5, if the authentication target does not match the data stored in advance, the predetermined value is set to a standard predetermined value stored in advance. This standard predetermined value corresponds to the race to be used and includes individual differences because the skin color varies from race to race and there are variations in the amount of hemoglobin component and blood flow due to individual differences. Is set as follows.

  In a succeeding step S6, it is determined whether or not the setting is changed by the remote controller (21). If it is determined in step S6 that the setting has been changed by the remote controller (21) (in the case of YES), the blood flow at that time is stored in the personal information storage unit (47) as correction information together with the setting change ( Step S7). Thereby, the detected blood flow volume can be associated with the setting change, and when air conditioning control is performed based on the blood flow volume, more appropriate air conditioning control can be performed in consideration of the setting change. Specifically, in the subsequent step S8, the correction information stored in the personal information storage unit (47) is taken into consideration, and first and second predetermined values as threshold values used in steps S9 and S14 described later are set. Set. At this time, a predetermined value corresponding to each individual identified in step S5 is read, and new first and second predetermined values are set with further consideration of the setting change for the predetermined value.

  Even when it is determined in step S6 that the setting has not been changed (in the case of NO), the process proceeds to step S8 to set the first and second predetermined values. The first and second predetermined values are set to values in consideration of the correction information stored in the personal information storage unit (47) corresponding to each individual identified in step S5. That is, when the setting is not changed in step S6, the value set in step S8 is a value corrected for each individual with respect to the standard value.

  In a succeeding step S9, it is determined whether or not the obtained blood flow is equal to or greater than a first predetermined value that is currently set. If it is determined in step S9 that the blood flow is greater than or equal to the first predetermined value (in the case of YES), it is estimated that the blood flow of the person in the space is large and feels hot. If it is determined that the room temperature at that time is equal to or higher than the temperature required for the cooling operation (third predetermined value) and it is determined in step S10 that the room temperature is required for the cooling operation (YES) In the case), the process proceeds to step S11 and the subsequent cooling operation. If it is determined in this step S10 that the room temperature is not necessary for the cooling operation (in the case of NO), since the cooling operation is unnecessary, the process returns to step S1 to acquire the face image again, and the blood Control according to the flow rate.

  After the air conditioning operation is changed to the cooling operation in step S11, it is determined in the subsequent step S12 whether or not the blood flow has changed after a predetermined period of time. If the blood flow has not changed (NO), the step is performed. After lowering the set temperature in S13, the process returns to step S12 again to determine the change in blood flow. On the other hand, when it is determined in step S12 that the blood flow has changed (in the case of YES), the process returns to the start (return), and air-conditioning control is performed again according to the blood flow. Here, the said predetermined period means the period until the blood flow rate of the person in space changes reliably after changing the preset temperature of air conditioning. That is, in steps S12 and S13, whether or not there is an effect at the current set temperature is confirmed by the change in the blood flow rate of the person in the space. The set temperature (set value) is lowered so as to approach a value (specified value) smaller than the predetermined value.

  If it is determined in step S9 that the blood flow is less than the first predetermined value (in the case of NO), the process proceeds to step S14 to determine whether the blood flow is equal to or less than the second predetermined value. If it is determined in step S14 that the blood flow is equal to or less than the second predetermined value (in the case of YES), it is estimated that the blood flow of the person in the space is small and feels cold. When it is determined that the room temperature at that time is equal to or lower than the temperature required for the heating operation (fourth predetermined value), it is determined in step S15 that the room temperature is required for the heating operation (YES) In the case), the process proceeds to step 16 and the subsequent heating operation. If it is determined in this step S15 that the room temperature is not required for heating operation (in the case of NO), the heating operation is unnecessary, so the process returns to step S1 to acquire a face image again and blood Control according to the flow rate.

  After the air conditioning operation is changed to the heating operation in step S16, it is determined in subsequent step S17 whether or not the blood flow has changed after a predetermined period of time. If the blood flow has not changed (in the case of NO), After raising the set temperature in step S18, the process returns to step S17 again to determine a change in blood flow. On the other hand, if it is determined in step S17 that the blood flow has changed (in the case of YES), the process returns to the start (return), and the air-conditioning control of FIG. 3 corresponding to the blood flow is performed again. That is, in steps S17 and S18, whether or not there is an effect at the current set temperature is confirmed by a change in the blood flow rate of the person in the space. If there is no effect, the blood flow rate is increased. The set temperature (set value) is increased so as to approach a value (specified value) larger than the predetermined value.

  When it is determined in step S14 that the blood flow is greater than the second predetermined value (in the case of NO), the blood flow is an amount between the first predetermined value and the second predetermined value, It is estimated that the temperature is not too hot or cold for humans, so without performing the air conditioning control thereafter, the process returns to step S1 to acquire a face image again and respond to the blood flow rate. Take control.

-Effect of the embodiment-
In the above embodiment, a face image of a person existing in a space to be air-conditioned is acquired, the amount of hemoglobin component is detected from the face image, the blood flow is obtained, and air-conditioning control is performed according to the blood flow. Therefore, the air conditioning control can be performed so that the temperature in the space is comfortable for a person without performing an input operation with the remote controller (21) or the like. Specifically, if the blood flow is equal to or higher than the first predetermined value, the cooling operation is performed, and if the blood flow is equal to or lower than the second predetermined value, the operation is automatically switched according to the blood flow. Can do. In conjunction with this, a change in the blood flow over time is also detected, and if there is no change in the blood flow for a predetermined period, the set temperature is changed, so that the temperature in the space is less than the first predetermined value, 2 It is possible to automatically change the temperature to an optimum temperature higher than a predetermined value.

  In addition, since the predetermined value is set in advance considering the race and individual differences, it is based on the blood flow obtained from the face image without being affected by the skin color difference or individual difference depending on the race. Therefore, it is possible to perform optimal air conditioning control for people in the space.

  Further, the controller (41) performs personal authentication by the personal authentication unit (46), and takes the correction value stored in correspondence with each individual in the personal information storage unit (47) to set the predetermined value. Since it is configured to set, the control of the air conditioning operation suitable for each individual can be performed with higher accuracy. Moreover, when operated by the remote control (21) or the like, the setting operation is stored in association with the blood flow volume at that time, and used for subsequent driving control. Thus, the air conditioning operation can be controlled with higher accuracy.

However, the present invention is not limited to this, and the predetermined value may be constant regardless of the individual or setting change. In this way, the control can be simplified. However, even in this case, it is preferable to set a value corresponding to a predetermined race or a value including individual differences in order to eliminate the influence of differences in skin color or individual differences.
