(Embodiment)
(1) Overview Hereinafter, an overview of the temperature detection device 1 and the air conditioning control system 10 according to the embodiment will be described with reference to FIG.

The air-conditioning control system 10 according to the embodiment is a system that is used for, for example, a mobile body such as a car, a train, an aircraft, and a ship, and performs air conditioning of an internal space (indoor space) of the mobile body. The moving body is an automobile 100 as an example. As shown in FIG. 1, the air conditioning control system 10 includes a temperature detection device 1, an air conditioning control device 2, and an air conditioner 3. The air conditioning control device 2 controls the air conditioner 3 in accordance with the detection result of the temperature detection device 1. In the embodiment, the air conditioner 3 is an air conditioner provided in the automobile 100. The air conditioner 3 may or may not be included in the air conditioning control system 10.

The temperature detection device 1 is a device for detecting temperature information of an object in a specific space. In the embodiment, the specific space is the indoor space S1 (see FIG. 3) of the automobile 100. The object is, for example, a person P1 (see FIG. 3) who is in the car 100. That is, the temperature detection device 1 according to the embodiment detects at least the temperature information of the person P1 in the indoor space S1 of the automobile 100. The "temperature information" in the present disclosure is information related to temperature, and in the case of a thermal image sensor like the first temperature sensor 11A and the second temperature sensor 11B described later, for example, radiation from the object P1 Is the amount of infrared energy that is As shown in FIG. 1, the temperature detection device 1 includes a first temperature sensor 11A, a second temperature sensor 11B, and two temperature sensor I /

Fs

12A and 12B may or may not be included in the temperature detection device 1.

Each of the first temperature sensor 11A and the second temperature sensor 11B is, for example, a thermal image sensor that acquires a thermal image. The "thermal image" in the present disclosure refers to an image in which infrared rays emitted from an object are analyzed and a heat distribution is represented as a diagram. The viewing angle θ2 (see FIG. 3) of the second temperature sensor 11B is narrower than the viewing angle θ1 (see FIG. 3) of the first temperature sensor 11A. Furthermore, the first visual field range R1 (see FIG. 3) which is the visual field range of the first temperature sensor 11A and the second visual field range R2 (see FIG. 3) which is the visual field range of the second temperature sensor 11B are at least partially Is different.

(2) Configuration Hereinafter, configurations of the temperature detection device 1 and the air conditioning control system 10 according to the embodiment will be described with reference to FIGS. 1 to 3.

The air conditioning control system 10 which concerns on embodiment is provided with the temperature detection apparatus 1, the air conditioning control apparatus 2, and the air conditioner 3 as shown in FIG. The air conditioning control device 2 controls the air conditioner 3 in accordance with the detection result of the temperature detection device 1.

(2.1) Temperature Detection Device As shown in FIG. 1, the temperature detection device 1 includes a first temperature sensor 11A, a second temperature sensor 11B, and a plurality of (two in FIG. 1) temperature sensor I / F 12A, And 12B. In the following description, when the first temperature sensor 11A and the second temperature sensor 11B are not distinguished from each other, the first temperature sensor 11A is also referred to as a "temperature sensor 11".

The temperature sensor 11 (the first temperature sensor 11A and the second temperature sensor 11B) is, for example, a thermal image sensor that generates data of a thermal image of 8 × 8 pixels. The temperature sensor 11 can detect the temperature distribution of the two-dimensional area by capturing infrared light with 8 × 8 pixels. The number of pixels of the thermal image is an example, and can be changed as appropriate.

The temperature sensor 11 includes a base 111, a case 112, a lens 113, a sensor chip, and an application specific integrated circuit (ASIC), as shown in FIG. The base 111 is made of, for example, a ceramic and has a rectangular shape when viewed from the front. The sensor chip and the ASIC are mounted on the surface of the base 111. On the sensor chip, 8 × 8 infrared detection elements are mounted. The sensor chip outputs each output signal of 8 × 8 infrared detection elements. The ASIC receives 8 × 8 output signals from the sensor chip to generate 8 × 8 pixel thermal image data. The case 112 is in the shape of a rectangular box whose one surface (the surface facing the base 111) is open. At the center of the bottom of the case 112, a rectangular opening 1121 is provided. The lens 113 is made of, for example, silicon (Si), and has a rectangular shape in a front view. The lens 113 is located in front of the sensor chip in a state where the temperature sensor 11 is assembled, and is exposed forward from the opening 1121 of the case 112.

The horizontal viewing angle θ1 of the first temperature sensor 11A is, for example, 60 degrees. The viewing angle θ2 in the horizontal direction of the second temperature sensor 11B is, for example, 30 degrees. That is, in the temperature detection device 1 according to the embodiment, the view angle θ2 of the second temperature sensor 11B is narrower than the view angle θ1 of the first temperature sensor 11A. As shown in FIG. 3, the first temperature sensor 11A and the second temperature sensor 11B are provided on the wall surface 101 of the automobile 100 as a moving body. The wall surface 101 of the automobile 100 is, for example, an A-pillar. In this case, if the lens 113 of the first temperature sensor 11A and the lens 113 of the second temperature sensor 11B are different in order to make the view angle θ1 of the first temperature sensor 11A different from the view angle θ2 of the second temperature sensor 11B. You may For example, the lens 113 of the first temperature sensor 11A is a wide-angle lens such that the view angle θ1 of the first temperature sensor 11A is wider than the view angle θ2 of the second temperature sensor 11B. In addition, the lens 113 of the first temperature sensor 11A and the lens 113 of the second temperature sensor 11B may be the same, and a wide-angle lens may be disposed in front of the first temperature sensor 11A.

As shown in FIG. 3, the first temperature sensor 11A detects temperature information of the object P1 included in the first visual field range R1. The first visual field range R1 is a quadrangular pyramid having the first temperature sensor 11A at the top. As shown in FIG. 3, the second temperature sensor 11B detects temperature information of the object P1 included in the second visual field range R2. The second visual field range R2 is a quadrangular pyramid whose top is the second temperature sensor 11B. The first visual field range R1 is a range including a region where the distances from the first temperature sensor 11A and the second temperature sensor 11B are closer than the second visual field range R2. Further, the second visual field range R2 is a range including a region where the distance from the first temperature sensor 11A and the second temperature sensor 11B is longer than the first visual field range R1. The first view range R1 and the second view range R2 are different at least in part. In the temperature detection device 1 according to the embodiment, as shown in FIG. 3, the first visual field range R1 and the second visual field range R2 do not overlap and differ in all the regions.

In the temperature detection device 1 according to the embodiment, for example, by lowering the sensitivity of the first temperature sensor 11A, the distance from the first temperature sensor 11A and the second temperature sensor 11B includes a region closer than the second visual field range R2. Thus, the first visual field range R1 is set. Further, in the temperature detection device 1 according to the embodiment, for example, by increasing the sensitivity of the second temperature sensor 11B, an area in which the distance from the first temperature sensor 11A and the second temperature sensor 11B is farther than the first visual field range R1. The second visual field range R2 is set to include the second visual field range R2.

As described above, the first temperature sensor 11A and the second temperature sensor 11B are thermal image sensors. Therefore, the first temperature sensor 11A generates thermal image data including the first visual field range R1. The second temperature sensor 11B generates data of a thermal image including the second visual field range R2. Moreover, in the temperature detection apparatus 1 which concerns on embodiment, 1st temperature sensor 11A and 2nd temperature sensor 11B are provided separately. In other words, the first temperature sensor 11A and the second temperature sensor 11B are physically separated. As described above, since the first temperature sensor 11A and the second temperature sensor 11B are physically separated, the first visual field range R1 and the second visual field range R2 can be adjusted separately.

The temperature sensor I / F 12A is an interface that connects the first temperature sensor 11A and the calculation unit 21 (described later) of the air conditioning control device 2. The temperature sensor I / F 12B is an interface that connects the second temperature sensor 11B and the calculation unit 21. The temperature sensor I / F 12A outputs the thermal image data from the first temperature sensor 11A to the calculation unit 21. Further, the temperature sensor I / F 12B outputs the thermal image data from the second temperature sensor 11B to the calculation unit 21. The temperature sensor I /

Fs

12A and 12B may be configured by one interface. In this case, the thermal image data from the first temperature sensor 11A and the thermal image data from the second temperature sensor 11B are output to the calculation unit 21 through one interface.

(2.2) Air Conditioning Control Device As shown in FIG. 1, the air conditioning control device 2 includes an arithmetic unit 21 and a setting unit 22.

The arithmetic unit 21 mainly includes, for example, a computer system having one or more processors and one or more memories. Then, the processor of the computer system executes the program recorded in the memory of the computer system, whereby the function of the arithmetic unit 21 is realized. The program may be pre-recorded in a memory, or may be provided through a telecommunication line such as the Internet or in a non-transitory recording medium such as a memory card.

The calculation unit 21 estimates the thermal sensation of the person P1 who got on the vehicle 100 as a moving object, based on the data of the thermal image from the first temperature sensor 11A and the data of the thermal image from the second temperature sensor 11B. Do. The "thermal sensation" in the present disclosure refers to a sensation of feeling hot or cold.

Hereinafter, the thermal sensation estimation algorithm by the calculating part 21 is demonstrated. The heat radiation amount H [W / m ² ] (hereinafter, also referred to as “human body heat radiation amount H”) from the human body is calculated by equation (1).

H = R + C + K + E _SK + E _res + C _res (1)

In the equation (1), "R" is the amount of heat radiation due to radiation (hereinafter also referred to as "radiation heat radiation R") and "C" is the amount of heat radiation due to convection (hereinafter referred to as "convection heat radiation C") is there. Further, “K” in the equation (1) is a heat release amount by conduction (hereinafter, also referred to as “conductive heat release amount K”), “E _sk ” is a heat release amount by water evaporation from the skin (hereinafter, “evaporation release It is also referred to as “heat amount E _sk ”. Further, “E _res ” in the equation (1) is a heat release amount by evaporation of moisture in the breath (hereinafter, also referred to as “evaporation heat _release amount E _res ”), “C _res ” is a heat release amount by convection of breath (hereinafter, Also referred to as “convective heat _release amount C _res ”.

The amount of conducted heat radiation K is generally small, and the convective heat radiation amount C _res is also small when in a resting state at a general room temperature range. Furthermore, when in the resting state, the evaporative heat _release amounts E _sk and E _res can also be regarded as substantially constant. Therefore, in the equation (1), only the radiant heat radiation amount R and the convective heat radiation amount C can be regarded as variables, so the human body heat radiation amount H can be estimated by only the radiant heat radiation amount R and the convective heat radiation amount C. Here, assuming that the radiative heat transfer rate is hr, the convective heat transfer rate is hc, the surface temperature of the human body is Tcl, the wall temperature is Tr, and the ambient temperature is Ta, the radiation heat release amount R is calculated by equation (2) The convection heat radiation amount C is calculated by the equation (3).

R = hr × (Tcl-Tr) (2)
C = hc × (Tcl-Ta) (3)

Then, assuming that the wall surface temperature Tr and the ambient temperature Ta are the same, the human body heat release amount H is calculated by the equation (4).

H = R + C = (hr + hc) x (Tcl-Tr) (4)

That is, if the surface temperature Tcl of the human body and the wall surface temperature Tr are known, the heat radiation amount H of the human body can be calculated. In other words, the heat radiation amount H of the human body can be calculated from the difference between the surface temperature Tcl of the human body and the wall surface temperature Tr. And since the calorific value of the human body in the resting state becomes a specific value, if the human body's heat radiation amount H can be calculated, the thermal sensation of the human body can be estimated.

Specifically, the calculation unit 21 sets the calorific value of the human body as a threshold value, and compares the threshold value with the human body heat radiation amount H. Then, when the human body heat release amount H is lower than the threshold value, the calculation unit 21 changes in the direction in which the body temperature increases, and thus, the human body is estimated to be feeling “hot”. In addition, when the human body heat release amount H exceeds the threshold value, the calculation unit 21 changes in the direction in which the body temperature decreases, so it is estimated that the human body feels "cold".

When it is estimated that the human body feels “hot”, the calculation unit 21 outputs a first control signal to lower the indoor temperature to the air conditioner 3. In addition, when it is estimated that the human body feels "cold", the calculation unit 21 outputs a second control signal for raising the indoor temperature to the air conditioner 3.

The setting unit 22 sets a threshold value to be compared with the human body heat release amount H calculated by the calculation unit 21. The threshold is, for example, the calorific value of the human body. The calorific value of the human body is a specific value in the resting state. Then, the calculation unit 21 can estimate the thermal sensation of the human body by comparing the heat radiation amount H with the threshold value set by the setting unit 22.

(2.3) Air Conditioning Device The air conditioning device 3 includes a control unit 31, a louver 32, a compressor 33, and a fan 34, as shown in FIG. In the embodiment, the air conditioner 3 is an air conditioner (car air conditioner) equipped in a car 100 as a moving body.

The control unit 31 mainly includes, for example, a computer system having one or more processors and one or more memories. Then, the processor of the computer system executes the program recorded in the memory of the computer system, whereby the function of the control unit 31 is realized. The program may be pre-recorded in a memory, or may be provided through a telecommunication line such as the Internet or in a non-transitory recording medium such as a memory card.

The control unit 31 controls at least one of the louver 32, the compressor 33, and the fan 34 in accordance with the first control signal or the second control signal from the calculation unit 21 of the air conditioning control device 2. The control unit 31 controls the louver 32 to control the wind direction of the cold air or the warm air emitted to the indoor space S1 (see FIG. 3) of the automobile 100. The control unit 31 controls the compressor 33 to compress the refrigerant (air conditioner gas). The control unit 31 controls the fan 34 to release cold air or warm air to the indoor space S1.

Specifically, the first temperature sensor 11A and the second temperature sensor 11B are provided on the wall surface 101 on the passenger seat 202 side. That is, the first temperature sensor 11A and the second temperature sensor 11B are provided in the indoor space S1 at a position closer to the assistant's seat 202 as a seat other than the driver's seat 201 than the driver's seat 201.
