  The emotion determination apparatus according to Embodiment 1 of the present invention is mounted on an air conditioning apparatus 100 as shown in FIGS. 1 and 2. The air conditioning apparatus 100 is an example of a device on which an emotion determination device is mounted. The air conditioning apparatus 100 provided with the emotion determination apparatus according to Embodiment 1 of the present invention is, for example, an indoor unit of an air conditioner. Therefore, the air conditioning apparatus 100 is installed on an indoor wall surface or ceiling surface. Here, it is assumed that the air conditioner 100 is installed on an indoor wall surface.

  As shown in FIGS. 1 and 2, the air conditioning apparatus 100 includes a housing 110. The casing 110 of the air conditioner 100 is formed in a substantially rectangular parallelepiped shape that is horizontally long and has a smooth curved surface from the front surface to the lower surface. A suction port 111 is formed on the upper surface of the housing 110. The suction port 111 is an opening for taking air into the housing 110 from the outside. An air outlet 112 is formed in the lower front portion of the housing 110. The air outlet 112 is an opening for discharging air from the inside of the housing 110 to the outside. The front upper portion of the housing 110 is covered with a front panel 113.

  Upper and lower wind direction plates 131, 132, 141, 142 are provided at the air outlet 112. These up-and-down wind direction plates are for adjusting the blowing angle in the vertical direction of the air blown out from the blow-out port 112.

  The up and down wind direction plates are respectively installed on the near side and the far side toward the front of the air conditioner 100. Further, the up and down wind direction plates on the near side and the far side are respectively divided into left and right. That is, the front side vertical wind direction plate is divided into a left front side vertical wind direction plate 131 on the left side and a right front side vertical wind direction plate 132 on the right side facing the front of the air conditioner 100. Further, the back side up / down wind direction plate is divided into a left back side up / down wind direction plate 141 and a right back side up / down wind direction plate 142 facing the front of the air conditioner 100.

  The position where each vertical wind direction plate is divided into right and left is substantially the center in the longitudinal direction (left and right direction of the air outlet 112) toward the front of the air conditioner 100. A slight gap is formed between the left front side vertical wind direction plate 131 and the right front side vertical wind direction plate 132. Similarly, a slight gap is also formed between the left back side vertical wind direction plate 141 and the right back side vertical wind direction plate 142.

  The left front side vertical wind direction plate 131, the right front side vertical wind direction plate 132, the left back side vertical wind direction plate 141, and the right back side vertical wind direction plate 142 are plate-like members extending in the left and right direction of the air outlet 112. Further, these up-and-down wind direction plates 131, 132, 141, 142 are each curved so that a cross section perpendicular to the longitudinal direction is arcuate.

  The up and down wind direction plates 131, 132, 141, and 142 are each attached to the housing 110 via support arms (not shown). Each support arm is rotatably attached to the housing 110. Each support arm rotates with respect to the housing 110 so that the direction of the vertical wind direction plate can be changed. And the air conditioning apparatus 100 can change the ventilation direction up and down by changing the direction of an up-and-down wind direction board.

  Each support arm of the vertical wind direction plate is provided so that the angle can be adjusted by driving a stepping motor for the vertical wind direction plate. Specifically, the directions of the left front side vertical wind direction plate 131 and the left back side vertical wind direction plate 141 are changed by the left vertical wind direction plate stepping motor 161 here. The directions of the right front side vertical wind direction plate 132 and the right back side vertical wind direction plate 142 are changed by the stepping motor 162 for the right vertical wind direction plate.

  In this manner, the vertical blowing angle (air blowing direction) of the air blown from the left side of the air outlet 112 and the vertical blowing angle (air blowing direction) of the air blown from the right side of the air outlet 112 are adjusted separately. be able to. Note that the left-side up / down wind direction plate stepping motor 161 and the right-side up / down wind direction plate stepping motor 162 are not shown in FIGS. 1 and 2.

  Left and right wind direction plates 150 are provided on the back side of the upper and lower wind direction plates 131, 132, 141, 142 at the air outlet 112. The left and right wind direction plates 150 are for adjusting the blowing angle in the left and right direction of the air blown from the blower outlet 112. The left and right wind direction plates 150 are configured by a plurality of plates arranged in the longitudinal direction (left and right direction of the air outlet 112) toward the front of the air conditioner 100. The left and right wind direction plates 150 are attached so that the angle can be adjusted by driving a stepping motor 163 for left and right wind direction plates (not shown in FIGS. 1 and 2), similarly to the upper and lower wind direction plates 131, 132, 141, 142. Yes.

  Inside the housing 110, an air passage that leads from the suction port 111 to the blower port 112 is formed. A heat exchanger 121 is installed on the leeward side of the suction port 111 in the air passage. The heat exchanger 121 exchanges heat with the air flowing through the air passage to heat or cool the air flowing through the air passage. Whether the air is heated or cooled depends on whether the air-conditioning apparatus 100 is in a heating operation or a cooling operation. Specifically, the heat exchanger 121 heats the air during the heating operation. On the other hand, the heat exchanger 121 cools the air during the cooling operation.

  The heat exchanger 121 adjusts the temperature, humidity, and the like of the air by heating or cooling the air flowing through the air path, and generates conditioned air. In this way, the heat exchanger 121 exchanges heat with the air sucked from the suction port 111 to generate conditioned air. Note that warm air is generated as conditioned air during heating operation, and cold air is generated as conditioned air during cooling operation.

  A blower fan 122 is installed on the leeward side of the heat exchanger 121 in the air path. The blower fan 122 is for generating an air flow from the inlet 111 to the outlet 112 in the air passage.

  When the blower fan 122 is operated, an air flow from the suction port 111 toward the blowout port 112 is generated in the air passage, air is sucked from the suction port 111, and air is blown out from the blowout port 112. The air sucked from the suction port 111 becomes an air flow passing through the air path inside the air conditioner 100 in the order of the heat exchanger 121 and the blower fan 122, and blows out from the air outlet 112. At this time, the direction (air blowing direction) of the wind blown out from the air outlet 112 is adjusted (changed) by the upper and lower wind direction plates 131, 132, 141, 142 and the left and right wind direction plates 150 arranged on the leeward side of the blower fan 122. The

  The blower fan 122, the up / down wind direction plates 131, 132, 141, 142, the left / right wind direction plate 150, the up / down wind direction plate stepping motors 161, 162, and the left / right wind direction plate stepping motor 163 are provided in a blower mechanism provided in the housing 110. Is configured. The air blowing mechanism configured as described above can generate an air flow that sucks air from the suction port 111 and blows out conditioned air from the blower outlet 112, and can change the wind direction of the conditioned air blown from the blower outlet 112.

  A human body sensor 170 is attached to the front center of the air conditioner 100. However, the mounting position of the human body sensor 170 is not limited to the center of the front surface of the air conditioning apparatus 100. For example, the human body sensor 170 may be attached to the left or right end of the housing 110.

  The human body sensor 170 includes, for example, a plurality of infrared sensors (light receiving elements) arranged in the vertical direction. Here, it is assumed that the human body sensor 170 includes, for example, eight infrared sensors (light receiving elements). Each of these eight infrared sensors is a detection element that can individually perform infrared light reception and temperature detection. For example, as shown in FIG. 3, these infrared sensors (light receiving elements) are arranged in a straight line in the vertical direction inside a cylindrical metal can 171. Accordingly, the human body sensor 170 has a function of detecting the room temperature by dividing it into eight areas having different heights.

  As shown in FIG. 3, the detection ranges of these eight infrared sensors are set as rectangular areas having the same size. The light distribution viewing angle of one infrared sensor is set such that, for example, the vertical light distribution viewing angle in the vertical direction is set to 7 °, and the horizontal light distribution viewing angle in the horizontal direction is set to 8 °.

  The light distribution viewing angle 173 of the whole human body sensor 170 that combines the light distribution viewing angles of the respective infrared sensors is set as an elongated area in the vertical direction. In addition, the light distribution viewing angle (detection range) of each infrared sensor does not need to have the same shape and the same size. Further, specific values of the vertical light distribution viewing angle and the horizontal light distribution viewing angle are not limited to the above-described examples. Further, the number of infrared sensors (light receiving elements) is not limited to eight, and the human body sensor 170 includes an arbitrary number of infrared sensors (light receiving elements) of 7 or less or 9 or more. Also good.

  The human body sensor 170 can change the direction of a plurality of infrared sensors arranged vertically by a sensor stepping motor 172 (not shown in FIGS. 1 and 2) to the left and right within a preset angle range. By doing in this way, each of the plurality of infrared sensors arranged vertically is scanned in the left-right direction, and within a preset detection range (hereinafter referred to as “temperature detection target range”) in front of the air conditioner 100. The surface temperature can be detected.

  With such a configuration, the human body sensor 170 scans the temperature detection target range and acquires the surface temperature distribution (thermal image) in the range in a non-contact manner. That is, the human body sensor 170 constitutes a temperature detection unit that detects a surface temperature within a preset detection range in a non-contact manner.

  The detection result of the human body sensor 170, that is, the surface temperature distribution (thermal image) data acquired by the human body sensor 170 is processed by the control device 180 or the like to include a person in the room from a temperature difference with the background, for example. The presence / absence and position of the heat source, the surface temperature of the human body, the body part of the human body (exposed and unexposed portions of the skin, head, etc.), etc. can be detected.

  In addition, based on the detection result of the human body sensor 170, the temperature sensed by the person in the room can also be obtained. In this case, the human body with exposed skin is more likely to detect the sensible temperature. Note that the detection accuracy of the human body sensor 170 increases as the number of pixels of the light receiving element used in the human body sensor 170 increases. Specifically, for example, if a light receiving element having 30 or more pixels is used, the position of a person in the room and the distance from the human body sensor 170 to the person can be accurately detected.

  The human body sensor 170 detects the temperature of the temperature detection target while scanning the temperature detection target range from side to side. Here, the left and right are the left and right when viewed from the air conditioner 100 side. When acquiring thermal image data (temperature distribution data) of indoor walls and floors, for example, the direction of the human body sensor 170 is moved left and right by the sensor stepping motor 172, and the rotation of the sensor stepping motor 172 (that is, the human body sensor). (Rotation in the direction of 170) is stopped for a certain time at every certain angle. The fixed angle at this time is set to 1 to 5 °, for example. Moreover, the fixed time in this case shall be 0.1-0.2 second, for example. Then, after the change of the orientation of the human body sensor 170 is stopped, it waits for a time shorter than the predetermined time (0.1 to 0.2 seconds), and the detection results of the eight light receiving elements of the human body sensor 170 (heat Image data).

  After the detection of the detection result by the human body sensor 170 is completed, the sensor stepping motor 172 is rotated again by the predetermined angle and stopped again, and the detection result (thermal image data) of the human body sensor 170 is acquired by the same operation. By repeating such an operation, the detection results of the human body sensor 170 are acquired at, for example, 90 to 100 locations in the left-right direction within the detection range. And the thermal image data (temperature distribution data) of the temperature detection target range can be obtained from the acquired detection result of the human body sensor 170.

  Next, the detection range of the human body sensor 170 configured as described above will be described with reference to FIGS. 4 and 5. First, FIG. 4 is a diagram for explaining the detection range of the human body sensor 170 in the depth direction as viewed from the air conditioning apparatus 100. This FIG. 4 has shown the state which looked at the room | chamber interior in which the air conditioning apparatus 100 was installed from the horizontal direction. In FIG. 4, the air conditioner 100 is installed at a height of about 1800 mm, and the state where the distance from the air conditioner 100 to the human body is about 3600 mm is illustrated.

  The detection range of the human body sensor 170 is divided into a plurality of regions equal to the number of infrared sensors (light receiving elements) (here, 8) in the depth direction. That is, the indoor space is divided into eight regions corresponding to the light distribution viewing angles of the respective light receiving elements in the depth direction. The width of each divided area is set according to the vertical spread angle of the light distribution viewing angle.

  The lowermost light receiving element of the human body sensor 170 detects the human body in the area on the near side closest to the air conditioning apparatus 100. The light receiving element on the upper side of the human body sensor 170 is configured to detect a human body in a far region.

  Next, FIG. 5 is a diagram for explaining the detection range of the human body sensor 170 in the left-right direction as viewed from the air conditioning apparatus 100. This FIG. 5 has shown the state which looked at the room | chamber interior in which the air conditioning apparatus 100 was installed from upper direction. The detection range of the human body sensor 170 is divided into a plurality of regions with respect to the predetermined angle when the human body sensor 170 is rotated by the sensor stepping motor 172 in the left-right direction.

  FIG. 5 illustrates a case where the detection range in the left-right direction of the human body sensor 170 is set to about 90 °. The detection range in the left-right direction of the human body sensor 170 is not limited to this angle. For example, the human body sensor 170 can be completely rotated by the sensor stepping motor 172, and the detection range is set to 360 °. May be.

  Note that the human body sensor 170 may also be swung in the vertical direction by another stepping motor or the like. By making the orientation of the human body sensor 170 changeable in the vertical direction, detailed thermal image data can be acquired not only in the horizontal direction but also in the vertical direction.

  The human body sensor 170 may be configured to use an infrared sensor and another detection device in combination. As a specific example, the position, shape, and distance to the human body may be detected using a camera, an ultrasonic sensor, or the like. That is, as the human body sensor 170, in addition to the infrared sensor, for example, an ultrasonic sensor capable of detecting an object may be further provided. By doing in this way, the detection accuracy of the position and distance of the human body by the human body sensor 170 can be improved. Or it is good also as a structure which detects the position of the human body in the depth direction (front-back direction) seen from the air conditioning apparatus 100 using the pyroelectric sensor using a Fresnel lens.

  Next, the configuration of the control system of the air conditioner 100 will be described with reference to FIG. The air conditioning apparatus 100 includes a control device 180 and an operation display unit 190. The control device 180 is configured by an electric circuit including, for example, a microcomputer. When the control device 180 includes a microcomputer, the control device 180 includes a processor 181 and a memory 182. The memory 182 stores a control program. The processor 181 reads and executes a program stored in the memory 182.

  When the processor 181 executes the control program, the control device 180 executes a preset process to control the operation of the air conditioner 100. In particular, the function of each part of the human body detection unit 183, the part specifying unit 184, the emotion determination unit 186, and the air blow control unit 187 described later is realized by the processor 181 executing the program stored in the memory 182. .

  A sensor system including a human body sensor 170 and the like is connected to the input side of the control device 180. On the output side of the control device 180, various actuators including a blower fan 122, a stepping motor 161 for the left and right wind direction plate, a stepping motor 162 for the right and left wind direction plate, a stepping motor 163 for the left and right wind direction plate, and a sensor stepping motor 172. Is connected.

  The operation display unit 190 is used by the user to input various setting values and also displays various information to the user. The operation display unit 190 is, for example, a remote controller (remote controller). The operation display unit 190 is connected to the control device 180 so as to be able to communicate with each other. By operating the operation display unit 190, the user can perform power ON / OFF, switching between heating operation and cooling operation, setting of temperature, wind direction, air volume, and the like. In addition, the operation display unit 190 includes a display device such as a liquid crystal display that displays various types of information. On the display device of the operation display unit 190, for example, setting contents such as an operation mode, temperature, wind direction, and air volume are displayed.

  The control device 180 drives each actuator based on inputs from the sensor system and the operation display unit 190, and controls the operation of the air conditioner 100. The control executed by the control device 180 includes, for example, control such as cooling operation, heating operation, air blowing operation, and scanning operation of the human body sensor 170. That is, the control device 180 controls the air blowing mechanism according to the detection result of the human body sensor 170 which is a temperature detection unit, for example.

  As illustrated in FIG. 7, the control device 180 includes a human body detection unit 183, a part specification unit 184, a storage unit 185, an emotion determination unit 186, a ventilation control unit 187, and a counting unit 188. The human body detection unit 183 detects a human body that exists within the temperature detection target range of the human body sensor 170 based on the detection result of the human body sensor 170 that is a temperature detection unit. The human body can be detected using, for example, the shape, distribution (relative positional relationship), area, and the like of each region where the surface temperature detected by the human body sensor 170 is equal to or higher than a preset reference temperature. The reference temperature at this time is specifically set to, for example, 30 ° C. in consideration of the human body temperature.

  The part specifying unit 184 specifies the determination part of the human body detected by the human body detecting unit 183. The determination part is a part of the human body that is used by the emotion determination unit 186 to determine the emotion of the subject of the human body. Which part of the human body is determined as the determination part is specified in advance. One or more determination parts are designated in advance. The determination part may be specified by first specifying the entire shape of the human body, and then specifying the determination part from the entire shape of the human body, or specifying the determination part directly. .

  When specifying the entire shape of the human body, the part specifying unit 184 first specifies a region where the human body detected by the human body detecting unit 183 exists. The region where the human body exists can be specified using, for example, the shape, distribution (relative positional relationship), area, and relative magnitude relationship of the temperature of each region where the surface temperature is equal to or higher than a certain temperature. In addition, if the area | region where a human body exists is specified, the shape of the said area | region will also be specified, ie, the shape of a human body can be specified.

  Moreover, when specifying the shape of the whole human body, the part specifying unit 184 may specify the entire area where the human body exists, or the area where the human body exists may be individually specified for each part of the human body. You may specify. In the case of individually specifying the region existing for each part of the human body, the part specifying unit 184, for example, for each part of the human head, chest, arm, upper leg, lower leg, hand and foot, Each of the areas where the Here, the “hand” refers to a portion on the tip side of the wrist. Further, the “foot” here refers to a portion on the tip side of the ankle.

  At this time, the part specifying unit 184 particularly sets a part where the surface temperature detected by the human body sensor 170 is equal to or higher than a preset temperature as a region where at least one of the head, chest, and abdomen of the human body exists. It may be specified. Moreover, when specifying the region where each part of the human body exists, the part specifying unit 184 may specify the temperature, position, and clothing state of each part. The “clothing state” is a state relating to whether the skin of the part is covered with clothes or the like or exposed.

  When the human body sensor 170 includes an ultrasonic sensor in addition to the infrared sensor that detects the surface temperature, the part specifying unit 184 determines whether the human body is based on the detection result of the infrared sensor and the detection result of the ultrasonic sensor. It is preferable to identify the region where the detected human body exists.

  Next, referring to FIG. 4 again, the specification of the region where each part of the human body exists by the part specifying unit 184 will be described with a specific example. In the example shown in FIG. 4, a human body is detected in the detection areas of the four light receiving elements from the uppermost side to the fourth side.

  Specifically, first, the uppermost light receiving element detects the head of the human body. The head is exposed and the skin temperature is higher than other parts of the human body, for example, a skin temperature of 30 ° C. or higher. Therefore, the part specifying unit 184 can identify the region to which the head of the human body belongs based on the thermal image data acquired by the human body sensor 170. More specifically, the part specifying unit 184 analyzes thermal image data acquired by the uppermost light receiving element by scanning in the horizontal direction. And when the shape of the heat source whose detected temperature is 30 ° C. or more in the horizontal direction matches the shape of the human head that is stored in advance (for example, a circular shape), this heat source is specified as the head.

  The second light receiving element from the top detects the chest and arms of the human body. The chest is almost always covered with clothes and the skin is rarely exposed. The arm portion may or may not be exposed to the skin. The part specifying unit 184 can determine whether or not the arm part is exposed based on the surface temperature detected by the human body sensor 170. Specifically, when the skin of the arm portion is exposed, a skin temperature equivalent to or slightly lower than that of the head is detected at a position corresponding to the arm portion. This is because the arm may be cooler than the head, and in this case, the temperature of the arm is detected as a temperature lower than the head.

  The third light receiving element from the top detects the upper leg of the human body. In most cases, the upper leg is covered with clothes. For this reason, the surface temperature of clothes is detected at a position corresponding to the upper leg. The surface temperature of the garment is lower than the temperature of the skin. In addition, when the hand is lowered to the side of the upper leg, a temperature equal to or lower than that of the head is detected at the position of the hand. The hand may be colder than the head. In this case, a temperature lower than that of the head is detected at the position of the hand.

  The fourth light receiving element from the top detects the lower leg of the human body. When the human body wears clothing such as socks, the surface temperature of the clothing is detected at the position of the lower leg. When the feet are cold, a temperature lower than the surface temperature of the clothing is detected at a position corresponding to the lower leg regardless of whether or not the clothing is worn.

  As for the human chest, arms, upper legs, lower legs, hands, and feet, as in the case of the head of the human body, the part specifying unit 184 determines the shape of the region above a certain temperature in advance. By comparing and comparing the shape of each part stored with each other, an area where each part exists is specified.

  Here, the temperature range detectable by the human body sensor 170 is preferably 0.5 ° C. or less. Mammals such as humans are constant temperature animals with a high ability to keep the body temperature constant. For this reason, in a steady state environment, the temperature of the human body surface, especially the head and trunk, hardly changes. Therefore, the resolution of the thermal image data acquired by the human body sensor 170 can be improved by reducing the temperature range that the human body sensor 170 can detect. Therefore, the human body surface temperature in the height direction of the trunk, such as the head and abdomen, hands, feet, etc., and the difference in the human body surface temperature in the left and right direction, for example, left hand, left chest, right chest, right hand, etc. can do. And it is possible to improve the identification accuracy of the part of a human body by the part specific | specification part 184. FIG.

  As described above, the human body sensor 170, the human body detection unit 183, and the site specifying unit 184, which are temperature detection units, constitute a site temperature detection unit. The part temperature detecting means is means for detecting the surface temperature of one or more predetermined determination parts of the subject's human body without contact with the subject's human body.

  The description will be continued with reference to FIG. 7 again. The emotion determination unit 186 and the storage unit 185 constitute an emotion determination unit that determines the emotion of the target person based on the surface temperature of one or more determination parts of the human body of the target person. The emotion determination unit 186 determines the emotion of the subject based on the surface temperature of one or more determination sites on the subject's human body. The determination part of the human body is a part specified by the part specifying unit 184 as the determination part among the parts of the human body. Here, the surface temperature of the determination part of the human body is detected by the human body sensor 170. That is, the surface temperature of one or more determination parts of the human body of the subject detected by the above-described part temperature detection means is used to determine the emotion of the subject in the emotion determination part.

  The emotion determination means determines basic emotions such as emotions. “Joy / Raku” is positive emotions such as joy and fun. When a positive emotion occurs in the subject, the temperature of the entire human body rises. “Angry” is, for example, a feeling of frustration or sneezing. The stronger the feeling of “anger”, the higher the temperature of the subject's head, for example. Further, in the case of a slight momentary frustration, only the temperature of a part of the subject's human body rises. “Sorrow” is a negative emotion such as sad, lonely, and spicy. When negative emotions occur in the subject, the temperature of the entire human body decreases.

  Specifically, for example, a case where the subject's emotion and the temperature change of the human body part during an office work using a personal computer with a chair seat rest will be described below. For example, when a problem occurs in the PC software and the subject is momentarily frustrated, the subject does not recognize the feeling that blood is rising on the head like when he is furious. However, at this time, it is observed that the temperature change of the subject's back begins to increase. On the other hand, the temperature of the subject's back is not changed and the temperature of the other parts is not changed in a state where the user's hand is repeatedly fed up without being frustrated.

  Therefore, in the first embodiment, the emotion determination unit 186 determines the emotion of the subject based on the amount of change in the surface temperature of the determination part of the subject's human body. That is, in this Embodiment 1, the memory | storage part 185 matches and memorize | stores the variation | change_quantity of the surface temperature of the determination part of a subject's human body, and the said subject's emotion. Here, the amount of change may be the absolute amount of change, the rate of change, or both. It is also desirable to take into account whether the change is an increase or a decrease, that is, whether the change is positive or negative.

  The emotion determination unit 186 refers to the information stored in the storage unit 185 to determine the emotion of the subject person. The emotion determination unit 186 first acquires detection result data by the part temperature detection means for the surface temperature of one or more determination parts of the subject's human body. Next, the emotion determination unit 186 determines the amount of change in the surface temperature at the determination part of the subject's human body from the detection result data. Hereinafter, the amount of change in the surface temperature at the determination site of the subject's human body, which is obtained from the detection result data, is referred to as “detection change amount”. Then, the emotion determination unit 186 collates the detected change amount with the information stored in the storage unit 185, and the emotion stored in the storage unit 185 in association with the value of the detected change amount is the emotion of the subject person. It is determined that

  Here, an example of a method for obtaining the detected change amount using the detection result data obtained by the above-described part temperature detecting means will be described. The emotion determination means acquires the surface temperature data for each determination part detected by the aforementioned part temperature detection means at regular intervals. Next, the acquired surface temperature data for each determination site is stored in, for example, the storage unit 185 and accumulated. And the emotion determination means can obtain | require the detection variation | change_quantity for every determination site | part based on the surface temperature data for every determination site | part for every fixed time.

  Specifically, for example, when it takes 30 seconds for the human body sensor 170 of the part temperature detection means to scan the entire detection range once, the above-mentioned fixed time is set to 30 seconds. Therefore, the surface temperature data for each determination part is acquired every 30 seconds and stored / accumulated. In this case, after the entire detection range is scanned once and the human body detection unit 183 detects the range where the human body exists, the human body sensor 170 does not include the entire detection range but the human body detected by the human body detection unit 183 exists. You may make it scan only within the range to perform. After the scanning range of the human body sensor 170 is narrowed to the range where the human body exists, the scanning cycle is shortened (for example, 30 seconds is shortened to 5 seconds). The emotion determination means may acquire, store, and accumulate surface temperature data for each determination region for each shortened scanning cycle. By doing in this way, the change of the surface temperature of the determination part of a human body can be detected with a shorter time interval.

  However, the time interval for obtaining the amount of change in the surface temperature at the determination part of the human body of the subject for emotion determination does not necessarily match the scanning cycle of the human body sensor 170. For example, an arbitrary time interval such as a minute unit such as several minutes or a day unit such as one day may be used.

  In addition, the memory | storage part 185 of an emotion determination means may be made to memorize | store the change amount of the surface temperature of the determination part of a subject's human body, and the said subject's emotion for every human work amount. . Here, the amount of work of a person refers to, for example, when a person is sitting, standing, resting, standing, or the like. The amount of change in surface temperature varies with the same emotion, because the amount of metabolism changes according to the amount of human work. Therefore, the emotion of the subject can be more accurately determined by taking into account the amount of work of the subject in the determination of emotion.

  The amount of human work can be obtained, for example, by detecting the posture of the human body, the amount of movement, and the like from the detection result of the human body detection unit 183 of the part temperature detection means. When the scanning is performed only within the range where the human body detected by the human body detection unit 183 exists, the amount of human work can be obtained from the change of the scanning range at this time. Further, for example, an ultrasonic sensor other than the human body sensor 170 may be provided to detect the amount of human work.

  Note that when the detection range of the human body sensor 170 is set in an environment where the amount of human work is constant, it is not necessary to take into consideration the amount of work of the target person in emotion determination. Specifically, for example, in an office, a study, etc., it is considered that a person is mostly in a sitting position. In addition, for example, in a training gym or the like, it is considered that a person is almost always standing. Therefore, such a place can be considered as an environment where the amount of human work is constant.

  The storage unit 185 may store the amount of change in the surface temperature of the determination part of the subject's human body and the emotion of the subject in association with each season such as summer and winter. Since the amount of human metabolism varies depending on the season, the amount of change in surface temperature varies even with the same emotion. Also, the amount of change in the surface temperature when holding the same emotion varies depending on the outside air temperature. Therefore, the emotion of the subject can be determined more accurately by taking the season into consideration. In addition, you may make it correct | amend and use the variation | change_quantity of the surface temperature of the determination part of a subject's human body according to a season. Specifically, for example, it is conceivable that the summer and winter seasons are corrected by multiplying by a seasonal coefficient with the intermediate period such as spring and autumn as a standard.

  The storage unit 185 may store the amount of change in the surface temperature of the determination part of the subject's human body and the emotion of the subject in association with each age group of the subject. For example, when comparing children with adults, it is generally known that children have higher skin temperatures than adults. Therefore, there is a possibility that the amount of change (for example, the rate of change) in the surface temperature of the determination site is smaller in children whose skin temperature is originally high than in adults. Therefore, the emotion of the subject can be determined more accurately by taking the age group of the subject into consideration. The age group of the subject can be obtained, for example, by detecting the height of the human body from the detection result of the human body detection unit 183 of the part temperature detection means. Alternatively, the user may input information on the age group of the target person by operating the operation display unit 190.

  The storage unit 185 may store the amount of change in the surface temperature of the determination part of the subject's human body and the subject's emotion in association with each other for each subject's exercise habits. It is generally known that the person with exercise habits and the person with no exercise habits have different basal metabolism, so that the person with exercise habits has a higher skin temperature. Therefore, there is a possibility that the amount of change (for example, the rate of change) in the surface temperature of the determination site is smaller for a person who has an exercise habit with a high skin temperature than a person who does not have an exercise habit. Therefore, the emotion of the subject can be more accurately determined by taking into account the presence or absence of the subject's exercise habits in the determination of emotion. At this time, for example, if the user can input in advance information regarding the presence / absence of the subject's exercise habits by operating the operation display unit 190, emotion determination in consideration of the presence / absence of the subject's exercise habits can be performed. It becomes possible.

  In addition, you may make it correct and use the variation | change_quantity of the surface temperature of the determination part of a subject's human body according to the said subject's basal metabolism amount. At this time, a means for detecting the subject's basal metabolic rate may be provided, or the user may input the subject's basal metabolic rate information in advance by operating the operation display unit 190. .

  The determination result of the emotion determination unit 186 is transmitted to the operation display unit 190. The display device of the operation display unit 190 displays the determination result of the emotion determination unit 186, that is, the emotion estimated to be held by the subject. The operation display unit 190 is an example of an output unit that outputs information on the emotion of the subject determined based on the surface temperature of the determination site of the subject's human body. That is, in this Embodiment 1, an output means outputs the determination result of the emotion determination part 186 as information regarding the said subject's emotion determined based on the surface temperature of the determination part of a subject's human body. And the output means is provided with the display part which displays the determination result of an emotion determination means.

  The output means outputs the determination result of the emotion determination means as one or more combinations of characters, numerical values, colors, and images. When the output means outputs the determination result of the emotion determination means as characters, the emotion determined by the emotion determination means is expressed by character information such as “happy”, “sad”, “lonely”, for example. When the output means outputs the determination result of the emotion determination means as a numerical value, the emotion determined by the emotion determination means is expressed by a scale value of a preset scale. As a scale at this time, for example, the degree of the positive emotion described above, the one-sided scale indicating the degree of negative emotion mentioned above, or the degree of both positive and negative emotions, for example. Bipolar scales can be used.

  When the output unit outputs the determination result of the emotion determination unit as a color, the emotion determined by the emotion determination unit is expressed in colors such as red, blue, yellow, and green, for example. When the output means outputs the determination result of the emotion determination means as an image, the emotion determined by the emotion determination means is expressed by facial expression images such as a laughing face, an angry face, and a crying face.

  In addition, although the conditions of the outside air temperature are the same and the same person has an overall painful feeling (negative feeling), it is the same. When the head temperature was compared, the head temperature on the day when the person's physical condition was poor was generally lower than the head temperature on the day when the person's physical condition was good. Therefore, particularly when the emotion determined by the emotion determination means is expressed numerically, the emotion may be expressed as a relative amount based on a certain time of the day, for example, when the operation of the emotion determination device starts. Moreover, you may make it determine the change of the emotion in a short time on the basis of several minutes before the same day.

  In the first embodiment, the emotion determination apparatus includes a counting unit 188. The counting unit 188 is a counting unit that counts the number of times the subject's emotion corresponds to the counting target emotion. The emotion to be counted is set in advance, for example, to the negative emotion described above, a feeling of depression such as “lonely”, “sad”, “spicy”, or the like.

  The counting result by the counting unit 188 may be stored in the storage unit 185. By doing in this way, the frequency | count etc. which were determined to hold | maintain the count object emotion within a fixed period, for example can be totaled. And it becomes possible to confirm the past history of a total result. In particular, emotions belonging to “sorrow” such as a feeling of depression may be worsened in the physical condition of the subject as the frequency increases. For this reason, the emotion determination target person can also utilize his / her physical condition management by knowing the counting result by the counting unit 188.

  The air blowing control unit 187 controls the operation of the air blowing mechanism by driving the actuators based on the input from the sensor system and the operation display unit 190. The operation of the air conditioner 100 is controlled. The control executed by the control device 180 includes, for example, control such as cooling operation, heating operation, air blowing operation, and scanning operation of the human body sensor 170.

  The air blow control unit 187 performs control of the air blow mechanism according to the detection result of the human body sensor 170 which is a temperature detection unit, for example. That is, for example, according to the position of the human body detected by the human body detection unit 183, the wind direction is directed to the human body, or conversely, the wind is not directly applied to the human body. Moreover, the ventilation control part 187 calculates a human body temperature (warm feeling) using the detection result of the human body sensor 170, and adjusts the temperature of the air blown according to body temperature. Therefore, in the first embodiment, the human body sensor 170 is installed for two purposes, that is, the purpose used for the emotion determination of the subject and the purpose used for the air flow control of the air conditioner 100.

  Moreover, you may make it the ventilation control part 187 use the information of the subject's emotion which the emotion determination part 186 determined as mentioned above for the operation control of the above-mentioned ventilation mechanism.

  Next, an example of the flow of the emotion determination operation of the air conditioning apparatus 100 including the emotion determination apparatus configured as described above will be described with reference to FIG. First, when the emotion determination operation is started, the human body sensor 170 starts detecting the surface temperature, and the human body detection unit 183 starts detecting the human body based on the detection result of the human body sensor 170. Then, when the human body detection unit 183 detects the human body of the subject of emotion determination based on the detection result of the human body sensor 170, in step S1, detection of the determination part of the human body of the target person and detection of the surface temperature of the determination part are performed. Start. That is, in step S1, the part specifying unit 184 first specifies a region where the human body detected by the human body detecting unit 183 is present. And the part specific | specification part 184 specifies each determination part of the said human body from the area | region where the human body which the human body detection part 183 detected exists. After step S1, the process proceeds to step S2.

  In step S2, in the human body sensor 170, the part specifying unit 184 starts detecting the surface temperature of each determination part. The human body sensor 170 detects the surface temperature of each determination part at regular time intervals. The surface temperature of each determination part detected by the human body sensor 170 is stored in the storage unit 185 as time series data. After step S2, the process proceeds to step S3.

  In step S <b> 3, first, the emotion determination unit 186 calculates the amount of change in the surface temperature of each determination region based on the time series data of the surface temperature of each determination region stored in the storage unit 185. Next, the emotion determination unit 186 determines whether the calculated change amount of the surface temperature of each determination portion, that is, the detected change amount is not 0, that is, whether the calculated surface temperature of each determination portion is changed. Confirm whether or not. If there is no change in the surface temperature of any of the determination parts, the process returns to step S2. On the other hand, if there is a change in any of the surface temperatures of each determination site, the process proceeds to step S4.

  In step S <b> 4, the emotion determination unit 186 collates the detected change amount with the information described in the storage unit 185 for each determination site where the surface temperature has changed. Then, the process proceeds to step S5, and when there is no information that matches the detected change amount in the information stored in the storage unit 185, the process returns to step S2. On the other hand, when the information stored in the storage unit 185 matches the detected change amount, the process proceeds to step S6.

  In step S6, the emotion determination unit 186 determines that the emotion stored in the storage unit 185 in association with the change amount of the surface temperature of the determination portion that matches the detected change amount is the emotion of the subject person. To do. And the emotion determination part 186 transmits the emotion determination result to the operation display part 190 which is an output means. The operation display unit 190 displays the emotion determination result on the display device. When the process of step S6 is completed, a series of emotion determination operations is completed.

  In addition, although the example which provided the emotion determination apparatus in the air conditioning apparatus 100 was demonstrated above, the installation method of an emotion determination apparatus is not restricted to this example. However, in order for the part temperature detection means to reliably detect the surface temperature of the determination part of the subject without contact, the whole body of the subject must fall within the detection range of the human body sensor 170 of the part temperature detection means. It is preferable to install an emotion determination device so that

  Other examples of such an installation method include a room air conditioner for home use, a package air conditioner for business use, a housing air conditioner, a device capable of generating conditioned air by a heat exchanger such as an air conditioner for automobiles, a television set, etc. The emotion determination device may be incorporated into a lighting device or the like installed on the ceiling surface of a movie apparatus, a building room, or an automobile room. By doing in this way, an emotion determination apparatus can be installed using the housing | casing of the existing apparatus. However, it is not hindered to configure the emotion determination device as a single device.

  Moreover, in the example demonstrated above, the site | part temperature detection means and the emotion determination means are provided in the housing | casing 110 of the air conditioning apparatus 100. FIG. And the operation display part 190 which is an output means is provided in the remote controller of the air conditioning apparatus 100, for example. The case of the remote controller can be regarded as a housing different from the housing 110. Therefore, each of the part temperature detection means, the emotion determination means, and the output means is provided in one of two or more cases.

  By providing the part temperature detecting means, the emotion judging means, and the output means of the emotion judging device in separate housings, a more space-saving emotion judging device comprising a single housing can be obtained. For example, it is conceivable that the surface temperature detection means is incorporated into a device such as an air conditioner or lighting equipment that is disposed at a position where the whole body of a person can be detected, and the emotion determination means and output means are incorporated into a television or other projection device. It is done.

  However, these part temperature detection means, emotion determination means, and output means may be provided in the same casing. For example, a display device that displays the emotion determination result by the emotion determination means may be provided in the casing 110 of the air conditioning apparatus 100.

  The emotion determination apparatus configured as described above includes a human body sensor 170, a human body detection unit 183, and a part that constitute part temperature detection means for detecting the surface temperature of one or more predetermined determination parts of the human body of the subject. Based on the specific part 184, the surface temperature of the determination part of the subject's human body, the storage part 185 and the emotion judgment part 186 constituting the emotion judgment means for judging the emotion of the subject person, and the judgment result of the emotion judgment means And an operation display unit 190 constituting output means for outputting.

  For this reason, the emotional state of the subject can be determined based on non-contact biometric information that is the surface temperature of a specific part of the human body. Therefore, the subject does not need to wear a device for acquiring biological information. And it is not necessary to impose psychological and physical stress accompanying the device wearing etc., and it is possible to accurately determine the emotion of the subject with a simple configuration.

Embodiment 2. FIG.
9 and 10 relate to Embodiment 2 of the present invention. FIG. 9 is a block diagram showing a functional configuration of the control device of the emotion determination device, and FIG. 10 shows a flow of operation of the emotion determination device. FIG.

  In Embodiment 2 described here, in the configuration of Embodiment 1 described above, the output unit includes a communication unit that transmits the determination result of the emotion determination unit to an external device. Hereinafter, the emotion determination apparatus according to the second embodiment will be described focusing on differences from the first embodiment.

  Also in the second embodiment, an example in which the emotion determination apparatus is provided in the air conditioning apparatus 100 will be described. The basic configuration of the air-conditioning apparatus 100 including the emotion determination apparatus is the same as that shown in FIGS. 1 to 6 described in the first embodiment.

  FIG. 9 shows the configuration of the control device 180 provided in the air conditioning apparatus 100 provided with the emotion determination apparatus according to the second embodiment. In the second embodiment, the control device 180 includes a communication unit 189. The communication unit 189 is for the emotion determination device to communicate with the external device 200.

  The external device 200 is provided so as to be able to communicate with the emotion determination device. The communication unit 189 of the emotion determination apparatus and the external device 200 perform information communication directly or via a communication network such as the Internet by a wired method, a wireless method, or a combination of these communication methods.

  The external device 200 is a device capable of communication between another person other than the target person of emotion determination and the target person. Specifically, the external device 200 is, for example, a mobile phone such as a smartphone, a fixed phone, a personal computer, or a tablet terminal.

  The communication unit 189 notifies the external device 200 when the determination result of the emotion determination unit 186 indicates that the subject's emotion corresponds to the notification target emotion. The notification target emotion is set in advance to, for example, the negative emotion described above, a feeling of depression such as “lonely”, “sad”, and “spicy”. The notification target emotion may be the same as or different from the counting target emotion described in the first embodiment. In this way, the output unit of the emotion determination device notifies the external device 200 when the emotion determination unit determines that the subject's emotion corresponds to the notification target emotion.

  At this time, the form in which the communication unit 189 of the output unit notifies the external device 200 of the determination result of the emotion determination unit is, as described in Embodiment 1, one or more combinations of characters, numerical values, colors, and images. Good. Further, the external device 200 may notify the determination result of the emotion determination means to the above-mentioned other person. The notification form at this time is also preferably a combination of one or more of characters, numerical values, colors, and images.

  When the external device 200 receives a notification from the communication unit 189 of the output unit, the external device 200 may start communication between the other person described above and the person who is subjected to emotion determination. In the communication at this time, it is conceivable to transmit arbitrary data such as voice data such as a call, image data such as a moving image or a still image, and character data such as e-mail.

  One of the acts that pleases parents as filial piety is conversation. And there is a survey result that it is pleased not only in face-to-face conversation but also in conversation through a communication medium such as a telephone. Therefore, in particular, when the person whose emotion is to be judged is an elderly parent who is living alone and the other person who has the external device 200 is a relative of the child, grandchildren, etc., the direct communication between the subject and the other person causes the Expected to relieve stress caused by negative emotions.

  Further, the communication unit 189 may transmit the counting result by the counting unit 188, the totaling result thereof, or the past history of the totaling result stored in the storage unit 185 to the external device 200. By doing in this way, the above-mentioned other person who watches over the emotion determination target person can grasp the emotion state of the target person in more detail.

  Next, an example of the flow of the emotion determination operation of the air conditioning apparatus 100 including the emotion determination device configured as described above will be described with reference to FIG. First, when the emotion determination operation is started, the human body sensor 170 starts detecting the surface temperature, and the human body detection unit 183 starts detecting the human body based on the detection result of the human body sensor 170. Then, when the human body detection unit 183 detects the human body of the subject of emotion determination based on the detection result of the human body sensor 170, in step S11, detection of the determination part of the human body of the target person and detection of the surface temperature of the determination part are performed. Start. That is, in step S11, first, the part specifying unit 184 specifies a region where the human body detected by the human body detecting unit 183 is present. And the part specific | specification part 184 specifies each determination part of the said human body from the area | region where the human body which the human body detection part 183 detected exists. After step S11, the process proceeds to step S12.

  In step S12, in the human body sensor 170, the part specifying unit 184 starts detecting the surface temperature of each determination part. The human body sensor 170 detects the surface temperature of each determination part at regular time intervals. The surface temperature of each determination part detected by the human body sensor 170 is stored in the storage unit 185 as time series data. After step S12, the process proceeds to step S13.

  In step S13, first, the emotion determination unit 186 calculates the amount of change in the surface temperature of each determination site based on the time-series data of the surface temperature of each determination site stored in the storage unit 185. Next, the emotion determination unit 186 determines whether the calculated change amount of the surface temperature of each determination portion, that is, the detected change amount is not 0, that is, whether the calculated surface temperature of each determination portion is changed. Confirm whether or not. If there is no change in the surface temperature of any of the determination sites, the process returns to step S12. On the other hand, if there is a change in any of the surface temperatures of each determination site, the process proceeds to step S14.

  In step S <b> 14, the emotion determination unit 186 collates the detected change amount with the information described in the storage unit 185 for each determination site where the surface temperature has changed. Then, the process proceeds to step S15, and when there is no information that matches the detected change amount in the information stored in the storage unit 185, the process returns to step S12. On the other hand, when the information stored in the storage unit 185 matches the detected change amount, the process proceeds to step S16.

  In step S16, the emotion determination unit 186 determines that the emotion stored in the storage unit 185 in association with the change amount of the surface temperature of the determination portion that matches the detected change amount is the emotion of the subject person. To do. Then, the emotion determination unit 186 confirms whether or not the determined emotion of the target person is the aforementioned notification target emotion. If the emotion determination result of the target person is the notification target emotion, the process proceeds to step S17.

  In step S <b> 17, the communication unit 189 establishes communication connection with the external device 200. And a process progresses to step S18, and the emotion determination part 186 transmits an emotion determination result to the communication part 189 which is an output means. Then, the communication unit 189 notifies the external device 200 of the emotion determination result. When the process of step S18 is completed, a series of emotion determination operations is completed.

  On the other hand, if the emotion determination result of the subject is not a notification target emotion in step S16, the process proceeds to step S18 without going through step S17. In this case, the emotion determination unit 186 transmits the emotion determination result to the operation display unit 190 that is an output unit. The operation display unit 190 displays the emotion determination result on the display device. When the process of step S18 is completed, a series of emotion determination operations is completed.

  The emotion determination apparatus configured as described above can achieve the same effects as those of the first embodiment. Furthermore, it is possible to watch the emotional state of the subject even if the subject is away from the subject of emotion determination.

  The emotion determination target of the emotion determination device according to the present invention is not limited to a human being. In addition, constant temperature animals such as dogs and cats having emotions such as mammals can be targeted for emotion determination.
