Detailed Implementation

[0009] The detection system according to embodiments will now be described in detail with reference to the accompanying drawings. Note that the drawings described in the following embodiments are schematic diagrams, and the dimensional ratios of components, etc., in these drawings do not necessarily correspond to their actual dimensional ratios. Furthermore, the configurations in the embodiments described below are merely examples of this disclosure. This disclosure is not limited to the embodiments described below, and various modifications can be made according to design, etc., as long as the effects of this disclosure are provided.

[0010] (Example) (1) Summary Figure 1 This is a schematic block diagram of the detection system 1 according to this embodiment.

[0011] The detection system 1 in this embodiment includes an environmental control device 10, an energy release unit 20, an acquisition unit 32, and a detector 33.

[0012] Environmental control device 10 is installed on ceiling surface 101 of room 100. Figure 2 On the other hand, it controls the environment in the interior space 103 of room 100.

[0013] The energy release unit 20 is capable of outputting electromagnetic wave energy, including at least one of light and heat, from the attachment position of the environmental control device 10 in a predetermined direction.

[0014] The acquisition unit 32 acquires distribution information, which includes at least one of first distribution information related to the electromagnetic field intensity distribution on the ceiling surface 101 of the room 100 and second distribution information related to the electromagnetic field intensity distribution on the floor surface 102 of the room 100.

[0015] The detector 33 detects attachment position information related to the attachment position of the environmental control device 10 on the ceiling surface 101 based on the distribution information acquired by the acquisition unit 32.

[0016] The detection system 1 of the present embodiment is used to detect attachment position information related to the attachment position of the environmental control device 10, for example, when the environmental control device 10 is installed or when the installation position of the environmental control device 10 is changed.

[0017] Here, the internal space 103 of the room 100 is a space below the ceiling surface 101. The internal space 103 is, for example, a space surrounded by walls, but can be open to the outside through an opening such as a window or an entrance / exit. The environmental control device 10 is a device that controls the environment in the internal space 103 of the room 100. The environment that is the control target of the environmental control device 10 can include, for example, the brightness environment and the temperature and humidity environment in the internal space 103. In the present embodiment, an example will be explained in which the environmental control device 10 is a lighting device 10A (see Fig. 1) that controls the brightness environment in the internal space 103 of the room 100, and the lighting device 10A as the environmental control device 10 controls the brightness in the internal space 103 of the room 100. Figure 2

[0018] Further, the attachment position information related to the attachment position of the environmental control device 10 on the ceiling surface 101 is, for example, position coordinates that show the attachment position of the environmental control device 10 on the ceiling surface 101 (for example, position coordinates in a two-dimensional orthogonal coordinate system with a predetermined position on the ceiling surface 101 as the origin). Note that the attachment position information related to the attachment position of the environmental control device 10 is not limited to position coordinates in a two-dimensional orthogonal coordinate system. The attachment position information can be position coordinates in a three-dimensional orthogonal coordinate system with a predetermined position of the room 100 as the origin, and can be changed accordingly, as long as it is information that can specify the attachment position of the environmental control device 10.

[0019] In the detection system 1 of the present embodiment, the energy release unit 20 outputs electromagnetic wave energy in a predetermined direction from the attachment position of the environmental control device 10, which can change at least one of the electromagnetic field intensity distribution on the ceiling surface 101 and the electromagnetic field intensity distribution on the floor surface 102. Since the acquisition section 32 acquires distribution information including at least one of the first distribution information related to the electromagnetic field intensity distribution on the ceiling surface 101 and the second distribution information related to the electromagnetic field intensity distribution on the floor surface 102, the detector 33 can detect the distribution of the electromagnetic wave energy output from the energy release unit 20 based on the distribution information acquired by the acquisition section 32. Therefore, the detector 33 can detect the position of the energy release unit 20 on the ceiling surface 101, that is, the attachment position information related to the attachment position of the environmental control device 10, based on the distribution information acquired by the acquisition section 32. Thus, the present embodiment can provide the detection system 1 capable of detecting the attachment position information related to the attachment position of the environmental control device 10.

[0020] ​Note that in the detection system 1 of the present embodiment, the detector 33 also detects attachment direction information related to an attachment direction of the environmental control device 10 on the ceiling surface 101. The attachment direction information is information for indicating a direction in which a reference direction of the housing 110 (see Figure 2 ) of the environmental control device 10 is pointing when the environmental control device 10 is installed on the ceiling surface 101. For example, when the housing 110 has an elongated shape and a long axis direction of the housing 110 is defined as the reference direction, the attachment direction information is information for indicating in which direction the reference direction (long axis direction) of the housing 110 is pointing on the ceiling surface 101. Detecting the attachment direction information with the detector 33 makes it possible to further specifically detect the attachment state of the environmental control device 10.

[0021] (2) Details With reference to Figures 1 to 6 , the detection system 1 according to the present embodiment will be described in detail below.

[0022] (2.1) Configuration In the present embodiment, it is assumed that the environmental control device 10 is a lighting device 10A, and it is assumed that the detection system 1 detects attachment position information related to an attachment position of the lighting device 10A. Figure 2 is a schematic view showing the internal space 103 of the room 100 in which the lighting device 10A as the environmental control device 10 is installed.

[0023] As described above, the detection system 1 includes the environmental control device 10 (in the present embodiment, the lighting device 10A) and the detection device 30. In addition, the detection system 1 also includes the sensor unit 40. The configuration of each component of the detection system 1 will be described below.

[0024] (2.1.1) Environmental Control Device The environmental control device 10 is installed on the ceiling surface 101 of the room 100. In the present embodiment, the environmental control device 10 is, for example, the lighting device 10A. For example, in Figure 2 , only one lighting device 10A is installed on the ceiling surface 101, but a plurality of lighting devices 10A can be installed on the ceiling surface 101, and the detection system 1 is able to detect attachment position information related to the respective attachment positions of the plurality of lighting devices 10A.

[0025] The environmental control device 10 (the lighting device 10A) includes a control unit 11, a function unit 12, an operation unit 13, an energy release unit 20, and a housing 110 (see Figure 2 ).

[0026] The housing 110 of the lighting device 10A is installed in a state in which a part of the housing 110 is embedded in the ceiling surface 101. The housing 110 has a rectangular shape when viewed from below.Figures 3 to 5 is a view of the lighting device 10A installed on the ceiling surface 101 as seen from below. In the following description, an X-axis direction extending along a long side of the housing 110 is referred to as a front / rear direction, a Y-axis direction extending along a short side of the housing 110 is referred to as a left / right direction, and a direction orthogonal to the X-axis direction and the Y-axis direction is referred to as an up / down direction. Further, a positive direction of the X-axis is defined as a front side, and a positive direction of the Y-axis is defined as a right side. However, these directions are merely examples and are not intended to limit the direction in which the environmental control device 10 is used. Further, arrows for indicating the respective directions are merely shown in the drawings for the purpose of description and are intangible.

[0027] The function unit 12 provides a function for controlling the environment in the internal space 103 of the room 100. When the environmental control device 10 is the lighting device 10A, the function unit 12 includes a light source 131 such as a light-emitting diode or a fluorescent lamp and a lighting circuit for causing the light source to light up. The function unit 12 provides a function for controlling the brightness in the internal space 103 of the room 100 (in other words, a function of illuminating the internal space 103).

[0028] The operation unit 13, for example, includes a push button switch on a surface of the housing 110 and receives an operation input given by a user. The operation unit 13 receives a switching operation for switching between an output state in which the energy release unit 20 outputs electromagnetic wave energy and a deactivation state in which the energy release unit 20 does not output electromagnetic wave energy. Further, since the energy release unit 20 of the present embodiment is capable of outputting electromagnetic wave energy in a plurality of directions, the operation unit 13 receives a switching operation for switching the direction in which the energy release unit 20 outputs electromagnetic wave energy to any one of the plurality of directions. Upon receiving the switching operation (for switching between the output state and the deactivation state, for switching between the output directions) given by the user, the operation unit 13 outputs a switching signal corresponding to the switching operation to the control unit 11. Note that the operation unit 13 can include a receiver for receiving a switching signal transmitted from a remote controller, and the user can switch between the output state and the deactivation state and can switch between the output directions by using the remote controller.

[0029] As described above, the energy release unit 20 is capable of outputting electromagnetic wave energy including at least one of light and heat in a predetermined direction from an attachment position of the environmental control device 10 (in the present embodiment, the lighting device 10A). In the present embodiment, the environmental control device 10 includes the energy release unit 20. That is, the energy release unit 20 is housed in the housing 110 of the lighting device 10A.

[0030] In the present embodiment, the energy releasing unit 20 is capable of outputting electromagnetic waves having thermal radiation in a predetermined direction. Examples of a device capable of outputting electromagnetic waves having thermal radiation include an infrared light emitting diode, a halogen lamp, and a heater, but in the present embodiment, an example in which the energy releasing unit 20 includes infrared light emitting diodes 21A to 21C (see FIG. 10) capable of outputting electromagnetic waves in the infrared region (infrared light) in a predetermined direction will be described. Note that the illustration of the infrared light emitting diode 21A is omitted in Figures 3 to 5 , and Figure 4 , and Figure 5 .

[0031] The infrared light emitting diode 21A is arranged substantially at the center of the housing 110. The center position of the housing 110 is a center position on the lower surface of the housing 110, and is a center position in the left / right direction and the front / back direction. In a state in which the housing 110 is mounted on the ceiling surface 101, the infrared light emitting diode 21A is capable of outputting infrared light vertically downward from substantially the center of the housing 110. The infrared light output from the infrared light emitting diode 21A is irradiated to an elliptical region Bl (see Figure 2 , and Figure 3 ) of the floor surface 102.

[0032] The infrared light emitting diode 21B is arranged substantially at the center in the longitudinal direction of the housing 110 at the right end portion of the housing 110. In a state in which the housing 110 is mounted on the ceiling surface 101, the infrared light emitting diode 21B is capable of outputting infrared light to the right from substantially the center of the long side of the housing 110. The infrared light output from the infrared light emitting diode 21B is irradiated to an elliptical region B2 that is a portion of the ceiling surface 101 and is on the right side of the housing 110 (see Figure 2 , and Figure 4 ).

[0033] The infrared light emitting diode 21C is arranged substantially at the center in the longitudinal direction of the housing 110 at the left end portion of the housing 110. In a state in which the housing 110 is mounted on the ceiling surface 101, the infrared light emitting diode 21C is capable of outputting infrared light to the left from substantially the center of the long side of the housing 110. The infrared light output from the infrared light emitting diode 21C is irradiated to an elliptical region B3 that is a portion of the ceiling surface 101 and is on the left side of the housing 110 (see Figure 2 , and Figure 5 ). Here, the infrared light emitting diode 21C and the infrared light emitting diode 21B are capable of outputting infrared light in directions opposite to each other with respect to the center position of the housing 110. Therefore, the region B2 irradiated by the infrared light from the infrared light emitting diode 21B and the region B3 irradiated by the infrared light from the infrared light emitting diode 21C are regions symmetrical with respect to a straight line passing through the center position of the housing 110 and parallel to the long axis direction of the housing 110.

[0034] The control unit 11 includes, for example, a computer system including one or more processors and one or more memory elements as main components. The processor(s) included in the computer system execute the program(s) stored in the memory element(s), thereby implementing the functions as the control unit 11. The program(s) can be stored in the memory element(s), can be provided through a telecommunication network such as the Internet, or can be distributed after stored in a non-transitory recording medium such as a memory card.

[0035] The control unit 11 controls the functional unit 12. For example, the control unit 11 controls the lighting circuit so that the light source is lit at a predetermined brightness. Note that the control unit 11 can control the lighting circuit to change the brightness of the light source so that the predetermined brightness is achieved in the internal space 103 of the room 100. Further, the control unit 11 controls in accordance with a switching signal input from the operation unit 13 so that the energy release unit 20 is in an output state of the electromagnetic wave having heat radiation in a predetermined direction, or a deactivation state.

[0036] (2.1.2) Sensor Unit In the present embodiment, the energy release unit 20 outputs the electromagnetic wave having heat radiation, and therefore, the sensor unit 40 includes a plurality of temperature sensors 41 arranged on the ceiling surface 101 and the floor surface 102 (see FIG. 1). The plurality of temperature sensors 41 are arranged at regular intervals in the X-axis direction and the Y-axis direction on each of the ceiling surface 101 and the floor surface 102. Here, the plurality of temperature sensors 41 are preferably arranged at intervals at which a temperature distribution in a state in which the energy release unit 20 outputs electromagnetic wave energy can be detected on each of the ceiling surface 101 and the floor surface 102. Figure 2

[0037] Each of the plurality of temperature sensors 41 detects the ambient temperature. Each of the plurality of temperature sensors 41 includes, for example, a sensing unit and an output section.

[0038] The sensing unit includes, for example, a thermal sensor such as a thermistor to detect the ambient temperature.

[0039] The output section outputs the sensing result of the sensing unit to the detection device 30. Each of the plurality of temperature sensors 41 is assigned a unique identification number, and the output section outputs the sensing result of the sensing unit and the identification number to the detection device 30. Note that the communication scheme between the output section of the temperature sensor 41 and the detection device 30 is, for example, a serial communication scheme such as RS485, but the communication scheme can be changed accordingly.

[0040] ​(2.1.3) detection device The detection device 30 includes a processing unit 31, a storage section 34, an operation unit 35, and an output section 36.

[0041] The storage section 34 includes, for example, memory elements such as read only memory (ROM) and random access memory (RAM). The storage section 34 stores sensor position information related to installation positions of temperature sensors 41 included in the sensor unit 40 in association with identification numbers of the temperature sensors 41. The storage section 34 stores, for example, data being calculated by the processing unit 31. Further, the storage section 34 stores attachment position information related to attachment positions of the environmental control device 10 and attachment direction information related to attachment directions of the environmental control device 10, which are determined by the detector 33.

[0042] The processing unit 31 includes, for example, a computer system including one or more processors and one or more memory elements as main components. The processor(s) included in the computer system execute the program(s) stored in the memory element(s), thereby realizing the functions as the processing unit 31. The program(s) can be stored in the memory element(s), can be provided through a telecommunication network such as the Internet, or can be distributed after stored in a non-transitory recording medium such as a memory card.

[0043] The processing unit 31 has the functions as the above-described acquisition section 32 and the detector 33. Note that the acquisition section 32 and the detector 33 merely show the functions realized by the processing unit 31, and do not necessarily embody tangible components.

[0044] The acquisition section 32 acquires the sensing results and the identification information from each of the plurality of temperature sensors 41 included in the sensor unit 40. Since the sensor position information related to the installation positions of the temperature sensors 41 and the identification numbers are stored in the storage section 34 in association with each other, the acquisition section 32 can acquire the temperature distribution on the ceiling surface 101 as the first distribution information and the temperature distribution on the floor surface 102 as the second distribution information based on the sensing results acquired from the plurality of temperature sensors 41. That is, the acquisition section 32 acquires the distribution information based on the sensing results of the plurality of temperature sensors 41 arranged on at least one of the ceiling surface 101 and the floor surface 102.

[0045] The detector 33 detects attachment position information related to the attachment position of the lighting device 10A on the ceiling surface 101 based on the distribution information acquired by the acquisition section 32. Note that, in the detection system 1 of the present embodiment, the detector 33 also detects attachment direction information related to the attachment direction of the environmental control device 10 on the ceiling surface 101. The housing 110 of the lighting device 10A has a rectangular shape when viewed from below, and the detector 33 also detects the direction in which the long axis direction (the direction in which the arrow D1 of FIG. 1 extends) of the housing 110 is directed. Note that the detection method for detecting the attachment position information and the attachment direction information with the detector 33 will be described in "(2.2) Description of the Operation". Figure 3

[0046] The operation unit 35 receives an operation input given by a user. The operation unit 35 includes an operation switch such as a push button switch, and an input device such as a keyboard and a mouse. Note that the operation unit 35 can be a unit that receives a voice-based operation instruction given by a user through voice recognition.

[0047] The output section 36 includes, for example, a display unit such as a liquid crystal display, and displays the attachment position information and the attachment direction information related to the environmental control device 10 determined by the detector 33 on the screen of the display unit.

[0048] (2.2) Description of the Operation Reference Figures 2 to 6 The processing for detecting the attachment position information related to the environmental control device 10 (the lighting device 10A in the present embodiment) installed on the ceiling surface 101 with the detection system 1 will be described below. Note that the flowchart shown in FIG. 2 is merely an example of the detection method for detecting the attachment position information related to the environmental control device 10 with the detection system 1 according to the present embodiment, and the order of the processing can be changed accordingly, or a processing (or plural processing) can be added or omitted accordingly. Figure 6 To start the processing for detecting the attachment position information related to the environmental control device 10, the user gives a switching operation to the operation unit 13 of the environmental control device 10 such that the electromagnetic wave energy is output in a predetermined direction. When the operation unit 13 receives the switching operation given by the user (step S1), the control unit 11 performs a release processing such that the energy release unit 20 outputs the electromagnetic wave energy in the predetermined direction based on the switching signal from the operation unit 13 (step S2). For example, the user performs a switching operation such that the energy release unit 20 outputs the electromagnetic wave energy downward, and the control unit 11 thereby causes the infrared light emitting diode 21A to output infrared light downward.

[0049]

[0050] ​​In a state where the energy releasing unit 20 outputs electromagnetic wave energy downward (i.e., the infrared light emitting diode 21A outputs infrared light downward), the user gives an operation to the operation unit 35 to instruct acquisition processing, and then the acquisition unit 32 acquires sensing results from the plurality of temperature sensors 41 (Step S3). The acquisition unit 32 acquires first distribution information related to the temperature distribution on the ceiling surface 101 and second distribution information related to the temperature distribution on the floor surface 102 on the basis of the sensing results acquired from the plurality of temperature sensors 41. Note that when the infrared light emitting diode 21A outputs infrared light downward, the infrared light from the infrared light emitting diode 21A is irradiated to the region B1 of the floor surface 102, and thus the region B1 irradiated with the infrared light can be detected by the temperature sensor 41 installed on the floor surface 102. When the infrared light emitting diode 21A outputs infrared light downward, it is sufficient for the acquisition unit 32 to acquire the second distribution information related to the temperature distribution on the floor surface 102, and thus the processing for acquiring the first distribution information related to the temperature distribution on the ceiling surface 101 is optional.

[0051] When the acquisition processing of the acquisition unit 32 is completed, the detector 33 performs detection processing for detecting attachment position information related to the lighting device 10A on the basis of the distribution information acquired by the acquisition unit 32 (Step S4).

[0052] Specifically, the detector 33 determines the region B1 that is a part of the floor surface 102 and is irradiated with the infrared light on the basis of the second distribution information acquired by the acquisition unit 32, and the detector 33 determines a center position of the region B1 as a position P1 directly below the lighting device 10A. In the present embodiment, the center position of the region irradiated with the infrared light means a barycentric position of a region whose temperature is higher than or equal to a predetermined threshold value. Then, the detector 33 determines position coordinates of a position on the ceiling surface 101 and directly above the position P1 as attachment position information related to the attachment position of the lighting device 10A.

[0053] When the attachment position information related to the attachment position of the lighting device 10A is determined, the detector 33 causes the storage unit 34 to store sensing results of the attachment position information and output the sensing results to the output unit 36. The output unit 36 displays the sensing results of the attachment position information on a screen of a display unit, for example (Step S5), and the user can confirm the sensing results of the attachment position information displayed on the screen of the display unit.

[0054] Now, processing for detecting attachment position information and attachment direction information related to the environmental control device 10 (the lighting device 10A in the present embodiment) installed on the ceiling surface 101 by the detection system 1 will be described.

[0055] To detect the attachment position information and the attachment direction information related to the lighting device 10A using the detection system 1, the acquisition unit 32 acquires the distribution information in each of a state in which the energy releasing unit 20 outputs electromagnetic wave energy (e.g., infrared light) having heat radiation to the right and a state in which the energy releasing unit 20 outputs electromagnetic wave energy to the left.

[0056] First, the user gives a switching operation for causing the electromagnetic wave energy to be output to the right to the operation unit 13 of the environmental control device 10, and then the operation unit 13 receives the switching operation given by the user, and the control unit 11 causes the infrared light emitting diode 21B to output infrared light to the right based on the switching signal from the operation unit 13. In the state in which the energy releasing unit 20 outputs electromagnetic wave energy to the right, the user gives an operation to the operation unit 35 to instruct the acquisition processing, and then the acquisition unit 32 acquires the sensing results from the plurality of temperature sensors 41. The acquisition unit 32 acquires the first distribution information related to the temperature distribution on the ceiling surface 101 and the second distribution information related to the temperature distribution on the floor surface 102 based on the sensing results acquired from the plurality of temperature sensors 41. When the infrared light emitting diode 21B outputs infrared light to the right, the infrared light from the infrared light emitting diode 21B is irradiated to the region B2 of the ceiling surface 101. Therefore, when the infrared light emitting diode 21B outputs infrared light to the right, it is sufficient for the acquisition unit 32 to acquire the first distribution information related to the temperature distribution on the ceiling surface 101, and thus the processing for acquiring the second distribution information related to the temperature distribution on the floor surface 102 is omitted.

[0057] Then, the user gives a switching operation for causing the electromagnetic wave energy to be output to the left to the operation unit 13 of the environmental control device 10, and then the operation unit 13 receives the switching operation given by the user, and the control unit 11 causes the infrared light emitting diode 21C to output infrared light to the left based on the switching signal from the operation unit 13. In the state in which the energy releasing unit 20 outputs electromagnetic wave energy to the left, the user gives an operation to the operation unit 35 to instruct the acquisition processing, and then the acquisition unit 32 acquires the sensing results from the plurality of temperature sensors 41. The acquisition unit 32 acquires the first distribution information related to the temperature distribution on the ceiling surface 101 and the second distribution information related to the temperature distribution on the floor surface 102 based on the sensing results acquired from the plurality of temperature sensors 41. When the infrared light emitting diode 21C outputs infrared light to the left, the infrared light from the infrared light emitting diode 21C is irradiated to the region B3 of the ceiling surface 101. Therefore, when the infrared light emitting diode 21C outputs infrared light to the left, it is sufficient for the acquisition unit 32 to acquire the first distribution information related to the temperature distribution on the ceiling surface 101, and thus the processing for acquiring the second distribution information related to the temperature distribution on the floor surface 102 is omitted.

[0058] When the acquisition unit 32 acquires the distribution information in each of the state in which the energy releasing unit 20 outputs infrared light to the right and the state in which the energy releasing unit 20 outputs infrared light to the left, the detector 33 performs processing for detecting attachment position information related to the attachment position of the lighting device 10A and attachment direction information related to the attachment direction thereof, on the basis of the distribution information acquired by the acquisition unit 32. First, the detector 33 determines the position coordinates of the center position P2 (see Figure 2 and Figure 4 ) of the region B2, which is a portion of the ceiling surface 101 and is irradiated with infrared light from the energy releasing unit 20, on the basis of the first distribution information in the state in which the energy releasing unit 20 outputs infrared light to the right. Then, the detector 33 determines the position coordinates of the center position P3 (see Figure 2 and Figure 5 ) of the region B3, which is a portion of the ceiling surface 101 and is irradiated with infrared light from the energy releasing unit 20, on the basis of the first distribution information in the state in which the energy releasing unit 20 outputs infrared light to the left. Upon determining the position coordinates of the center positions P2 and P3 of the regions B2 and B3, respectively, the detector 33 calculates the position coordinates of the midpoint P6 (see Figure 5 ) between the two center positions P2 and P3 to determine the coordinates of the midpoint P6 as the position information related to the attachment position of the lighting device 10A. Further, the detector 33 determines the direction in which a straight line L1 (see Figure 5 ) extending along the line segment connecting the center positions P2 and P3 through the midpoint P6 between the two center positions P2 and P3 and the normal line of the ceiling surface 101 is directed as the direction in which the reference direction of the housing 110 is directed, and determines information (for example, vector information) representing the straight line L1 as the attachment direction information.

[0059] Upon determining the attachment position information and the attachment direction information related to the lighting device 10A, the detector 33 causes the storage unit 34 to store the sensing results of the attachment position information and the attachment direction information, and outputs these sensing results to the output unit 36. The output unit 36 displays the sensing results of the attachment position information and the attachment direction information on the screen of a display unit, for example, and the user can confirm the sensing results of the attachment position information and the attachment direction information displayed on the screen of the display unit. As described above, the detector 33 also detects the attachment direction information related to the attachment direction of the environmental control device 10 on the ceiling surface 101, and thereby can further minutely detect the attachment state of the environmental control device 10.

[0060] Note that when the infrared light emitting diode 21B outputs infrared light to the right and when the infrared light emitting diode 21C outputs infrared light to the left, it is enough for the acquisition unit 32 to acquire the first distribution information related to the temperature distribution on the ceiling surface 101, and thus, the processing for acquiring the second distribution information related to the temperature distribution on the floor surface 102 is negligible. Further, the acquisition unit 32 can acquire the distribution information in a state where the infrared light emitting diodes 21B and 21C output infrared light to the right and to the left, respectively. In this case, the acquisition unit 32 can perform the acquisition processing in one step.

[0061] Further, in Figure 2 In the above embodiment, one lighting device 10A is installed on the ceiling surface 101 of the room 100, but a plurality of lighting devices 10A can be installed on the ceiling surface 101 of the room 100. In this case, the detection system 1 can perform the detection processing on each of the plurality of lighting devices 10A, thereby detecting the attachment position information related to the attachment position of each of the plurality of lighting devices 10A and the attachment direction information related to the attachment direction thereof.

[0062] (3) Modified Example The above embodiment is merely an example of various embodiments of the present disclosure. The above embodiment can be variously modified according to design or the like, as long as the object of the present disclosure is achieved.

[0063] A modified example of the above embodiment will be listed below. Any of the modified examples to be described below can be appropriately combined. Further, in the following description, the embodiment can be referred to as a basic configuration.

[0064] A function similar to the detection system 1 can be implemented, for example, by a detection method, a computer program, or a non-transitory recording medium including a program stored therein. The detection method according to an aspect includes an energy release processing, an acquisition processing, and a detection processing. The energy release processing includes causing an energy release unit to output electromagnetic wave energy including at least one of light and heat in a predetermined direction from an attachment position of an environmental control device 10. The environmental control device 10 is installed on a ceiling surface 101 of a room 100 to control an environment in an internal space 103 of the room 100. The acquisition processing includes acquiring distribution information including at least one of first distribution information related to an electromagnetic field intensity distribution on the ceiling surface 101 of the room 100 and second distribution information related to an electromagnetic field intensity distribution on a floor surface 102 of the room 100. The detection processing includes detecting attachment position information related to the attachment position of the environmental control device 10 on the ceiling surface 101 based on the distribution information acquired in the acquisition processing. The (computer) program according to an aspect is a program for causing a computer system to execute the detection method.

[0065] The main body that executes the detection system 1 and the detection method in the present disclosure includes a computer system. The computer system can include a processor and a memory element as its main hardware components. The processor executes a program stored in the memory element of the computer system, thereby realizing the function as the main body that executes the detection system 1 and the detection method in the present disclosure. The program can be stored in advance in the memory of the computer system. Alternatively, the program can also be downloaded through a telecommunications network, or distributed after having been recorded in a certain non-transitory storage medium such as a memory card, an optical disc, or a hard disk drive, any of which is readable by the computer system. The processor of the computer system can be constituted by a single or a plurality of electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). As used herein, an "integrated circuit" such as an IC or an LSI is referred to by different names according to the degree of integration thereof. Examples of the integrated circuit include a system LSI, a very large scale integrated circuit (VLSI), and an ultra large scale integrated circuit (ULSI). Alternatively, a field programmable gate array (FPGA) to be programmed after manufacturing the LSI, or a reconfigurable logic device that allows reconfiguration of the connection or the circuit section inside the LSI, can also be employed as the processor. These electronic circuits can be integrated together on a single chip or distributed on a plurality of chips, whichever is appropriate. These plurality of chips can be integrated together in a single device or distributed in a plurality of devices without limitation. As used herein, a "computer system" includes a microcontroller that includes one or more processors and one or more memories. Thus, the microcontroller can also be realized as a single or a plurality of electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0066] Further, in the above description, a plurality of functions of the detection system 1 are integrated together in a single housing. However, this is merely an example, and not a necessary configuration of the detection system 1. Alternatively, these components of the detection system 1 can be distributed in a plurality of different housings. Further, at least a part of the functions of the detection system 1 (for example, a part of the functions of the detector 33) can be realized, for example, by cloud computing.

[0067] On the contrary, in the first embodiment, at least a part of the functions of the detection system 1 distributed in a plurality of devices can be integrated together in a single housing. For example, the detection device 30 and the sensor unit 40 can be integrated together in a single housing.

[0068] In this embodiment, the plurality of temperature sensors 41 are arranged on the ceiling surface 101 and the floor surface 102, but the plurality of temperature sensors 41 do not necessarily have to be fixed to the ceiling surface 101 and the floor surface 102. In order to detect the attachment position information and the attachment direction information related to the lighting device 10A, the plurality of temperature sensors 41 can be temporarily arranged on the ceiling surface 101 and the floor surface 102.

[0069] In this embodiment, the energy release unit 20 is housed in the housing 110 of the lighting device 10A as the environmental control device 10, but the energy release unit 20 can be provided attachably and detachably to the housing 110 of the environmental control device 10.

[0070] (3.1) First modification example Based on Figure 7 A detection system 1 according to the first modification example will be described.

[0071] The detection system 1 of the first modification example differs from the detection system of the basic configuration in that the energy release unit 20 is capable of selectively outputting electromagnetic wave energy vertically downward, obliquely rightward downward, or obliquely leftward downward.

[0072] The energy release unit 20 includes, for example, infrared light emitting diodes capable of outputting infrared light as electromagnetic waves having heat radiation. More specifically, the energy release unit 20 includes, for example, an infrared light emitting diode capable of outputting infrared light vertically downward from the environmental control device 10, an infrared light emitting diode capable of outputting infrared light obliquely rightward downward from the environmental control device 10, and an infrared light emitting diode capable of outputting infrared light obliquely leftward downward from the environmental control device 10. Here, an angle formed between an optical axis of the infrared light emitting diode capable of outputting infrared light obliquely rightward downward and a direction of gravity and an angle formed between an optical axis of the infrared light emitting diode capable of outputting infrared light obliquely leftward downward and the direction of gravity are set to the same angle. Note that considering that the two angles are the same in the present embodiment is not limited to the two angles being exactly the same, but can include the two angles differing from each other by several degrees.

[0073] When the energy release unit 20 selectively outputs infrared light vertically downward, obliquely rightward downward, or obliquely leftward downward, it is enough that the plurality of temperature sensors 41 are mounted only on the floor surface 102 and the acquisition unit 32 acquires only the second distribution information related to the electromagnetic field intensity distribution on the floor surface 102 of the room 100. Note that components common to the detection system 1 of the basic configuration are denoted by the same reference numerals, and the description thereof is omitted.

[0074] In order to detect the attachment position of the lighting device 10A with the detection system 1 of the first modification example, the energy release unit 20 outputs infrared light vertically downward.

[0075] In a state where the energy release unit 20 outputs infrared light downward, the acquisition unit 32 acquires sensing results from the plurality of temperature sensors 41. The acquisition unit 32 acquires the second distribution information related to the temperature distribution on the floor surface 102 based on the sensing results acquired from the plurality of temperature sensors 41.

[0076] When the acquisition processing of the acquisition section 32 ends, the detector 33 performs processing for detecting attachment position information related to the attachment position of the lighting device 10A on the basis of the second distribution information acquired by the acquisition section 32. The detector 33 determines a region B1 (see FIG. 10) that is a part of the floor surface 102 and is irradiated with infrared light from the second distribution information acquired by the acquisition section 32, and the detector 33 determines a center position of the region B1 as a position P1 directly below the lighting device 10A. Then, the detector 33 determines position coordinates of a position on the ceiling surface 101 and directly above the position P1 as the attachment position information related to the attachment position of the lighting device 10A. Figure 7 ), and the detector 33 determines a center position of the region B1 as a position P1 directly below the lighting device 10A. Then, the detector 33 determines position coordinates of a position on the ceiling surface 101 and directly above the position P1 as the attachment position information related to the attachment position of the lighting device 10A.

[0077] Further, in order to detect the attachment position information and the attachment direction information related to the lighting device 10A with the detection system 1 of the first modified example, the energy releasing unit 20 outputs infrared light obliquely to the right and obliquely to the left, respectively.

[0078] First, the user gives a switching operation of causing infrared light to be output obliquely to the right to the operation unit 13 of the environment control device 10, and then the operation unit 13 receives the switching operation given by the user, and the control unit 11 causes the energy releasing unit 20 to output infrared light obliquely to the right on the basis of the switching signal from the operation unit 13. In a state where the energy releasing unit 20 outputs infrared light obliquely to the right, the user gives an operation to instruct acquisition processing to the operation unit 35, and then the acquisition section 32 acquires sensing results from the plurality of temperature sensors 41. The acquisition section 32 acquires second distribution information related to a temperature distribution on the floor surface 102 on the basis of the sensing results acquired from the plurality of temperature sensors 41.

[0079] Then, the user gives a switching operation of causing infrared light to be output obliquely to the left to the operation unit 13 of the environment control device 10, and then the operation unit 13 receives the switching operation given by the user, and the control unit 11 causes the energy releasing unit 20 to output infrared light obliquely to the left on the basis of the switching signal from the operation unit 13. In a state where the energy releasing unit 20 outputs infrared light obliquely to the left, the user gives an operation to instruct acquisition processing to the operation unit 35, and then the acquisition section 32 acquires sensing results from the plurality of temperature sensors 41. The acquisition section 32 acquires second distribution information related to a temperature distribution on the floor surface 102 on the basis of the sensing results acquired from the plurality of temperature sensors 41.

[0080] When the acquisition unit 32 acquires the second distribution information in each of the state in which the energy release unit 20 outputs infrared light obliquely downward to the right and the state in which the energy release unit 20 outputs infrared light obliquely downward to the left, the detector 33 performs processing for detecting attachment position information related to the attachment position of the lighting device 10A and attachment direction information related to the attachment direction thereof, on the basis of the second distribution information acquired by the acquisition unit 32. First, the detector 33 determines the position coordinates of the center position P4 (see Figure 7 ) of the region B4 that is a part of the floor surface 102 and is irradiated with infrared light from the energy release unit 20, on the basis of the second distribution information in the state in which the energy release unit 20 outputs infrared light obliquely downward to the right. Then, the detector 33 determines the position coordinates of the center position P5 (see Figure 7 ) of the region B5 that is a part of the floor surface 102 and is irradiated with infrared light from the energy release unit 20, on the basis of the second distribution information in the state in which the energy release unit 20 outputs infrared light obliquely downward to the left. Here, the angle formed between the optical axis of the infrared light emitting diode that can output infrared light obliquely downward to the right and the direction of gravity and the angle formed between the optical axis of the infrared light emitting diode that can output infrared light obliquely downward to the left and the direction of gravity are the same angle, and thus the two regions B4 and B5 are regions that are symmetrical with respect to a straight line that passes through the position directly below the center position of the lighting device 10A and is parallel to the long axis direction of the lighting device 10A.

[0081] Thus, after the position coordinates of the center positions P4 and P5 of the regions B4 and B5, respectively, are determined, the detector 33 calculates the position coordinates of the midpoint between the two center positions P4 and P5 to determine the position coordinates of the position on the ceiling surface 101 and directly above the midpoint between the center positions P4 and P5 as the position information related to the attachment position of the lighting device 10A. Further, the detector 33 determines a straight line that is orthogonal to both the line segment that passes through the midpoint between the center positions P4 and P5 and connects the center positions P4 and P5 to each other and the normal line of the floor surface 102, and the detector 33 determines the direction that extends along the straight line that is on the ceiling surface 101 and is parallel to the above-mentioned determined straight line that is orthogonal to the line segment and the normal line as the attachment direction information related to the attachment direction of the housing 110.

[0082] As described above, also in the detection system 1 of the first modified example, the detector 33 can detect the attachment position information related to the attachment position of the lighting device 10A and the attachment direction information related to the attachment direction of the lighting device 10A.

[0083] Note that in the first modification example, the plurality of temperature sensors 41 are arranged on the floor surface 102, but the plurality of temperature sensors 41 do not necessarily have to be fixed to the floor surface 102. In order to detect the attachment position information and the attachment direction information relating to the lighting device 10A, the plurality of temperature sensors 41 can be temporarily arranged on the floor surface 102.

[0084] (3.2) Second Modification Example Based on Figure 8 and Figure 9 A detection system 1 according to the second modification example will be described.

[0085] The detection system 1 of the second modification example differs from the detection system 1 of the basic configuration and the first modification example in that the sensor unit 40 includes a plurality of infrared imaging cameras 42 arranged on the ceiling surface 101 and the floor surface 102.

[0086] Each of the plurality of infrared imaging cameras 42 arranged on the ceiling surface 101 includes an infrared imager sensitive to light in an infrared region, and captures an infrared image of the floor surface 102. Each of the plurality of infrared imaging cameras 42 arranged on the floor surface 102 captures an infrared image of the ceiling surface 101.

[0087] Therefore, the acquisition unit 32 can acquire second distribution information relating to an electromagnetic field intensity distribution (e.g., a temperature distribution) on the floor surface 102, based on images captured by the plurality of infrared imaging cameras 42 arranged on the ceiling surface 101. Further, the acquisition unit 32 can acquire first distribution information relating to an electromagnetic field intensity distribution (e.g., a temperature distribution) on the ceiling surface 101, based on images captured by the plurality of infrared imaging cameras 42 arranged on the floor surface 102.

[0088] Therefore, the detector 33 can detect at least one of attachment position information relating to an attachment position of the environmental control device 10 (e.g., the lighting device 10A) and attachment direction information relating to an attachment direction thereof, based on the first distribution information and the second distribution information acquired by the acquisition unit 32.

[0089] Note that when the energy releasing unit 20 outputs electromagnetic wave energy only downward, the infrared imaging cameras 42 for capturing infrared images of the ceiling surface 101 are not necessary, and it is enough that only infrared imaging cameras 42 for capturing images of the floor surface 102 are installed on the ceiling surface 101.

[0090] Further, it is not necessary that the infrared imaging cameras 42 for capturing infrared images of the ceiling surface 101 and the floor surface 102 are fixed to the floor surface 102 and the ceiling surface 101, respectively. The infrared imaging cameras 42 can be temporarily arranged to detect the attachment position information and the attachment direction information relating to the lighting device 10A.

[0091] Thus, in the detection system 1 of the second modification example, the acquisition unit 32 acquires the distribution information on at least one of the ceiling surface 101 and the floor surface 102 based on an image captured by the infrared imager that is sensitive to light in the infrared region. Since the acquisition unit 32 acquires the distribution information based on the image captured by the infrared imager, the acquisition unit 32 can easily perform the processing for acquiring the distribution information as compared to a case where the distribution information is acquired based on the sensing results of the plurality of temperature sensors 41.

[0092] Note that, in the detection system 1 of the second modification example, the plurality of infrared imaging cameras 42 are installed on the ceiling surface 101, but the number of the infrared imaging cameras 42 arranged on the ceiling surface 101 can be one as long as an image of a region that is a part of the floor surface 102 and to which electromagnetic wave energy output from the energy release unit 20 is output can be captured by a single infrared imaging camera 42. Similarly, in the detection system 1 of the second modification example, the plurality of infrared imaging cameras 42 are installed on the floor surface 102, but the number of the infrared imaging cameras 42 arranged on the floor surface 102 can be one as long as an image of a region that is a part of the ceiling surface 101 and to which electromagnetic wave energy output from the energy release unit 20 is output can be captured by a single infrared imaging camera 42.

[0093] Note that, in the detection system 1 of the second modification example, the sensor unit 40 includes the plurality of infrared imaging cameras 42, but the sensor unit 40 is not limited to a unit including the infrared imaging cameras 42. The sensor unit 40 may, for example, include infrared detection sensors such as infrared array sensors that are capable of detecting the distribution of light in the infrared region on the ceiling surface 101 or the floor surface 102.

[0094] That is, the acquisition unit 32 can acquire the distribution information based on the sensing results of a plurality of infrared detection sensors arranged on at least one of the ceiling surface 101 and the floor surface 102. Each of the plurality of infrared detection sensors receives light in the infrared region and outputs an electric signal corresponding to the amount of light thus received. Since the acquisition unit 32 acquires the distribution information based on the sensing results of the plurality of infrared detection sensors arranged on at least one of the ceiling surface 101 and the floor surface 102, an advantage is provided in that the sensor unit 40 can be implemented at a low cost as compared to a case where the infrared imaging cameras 42 are employed.

[0095] (3.3) Third Modification Example The detection system 1 of the third modification differs from the basic configuration and the first and second modifications in that the energy releasing unit 20 outputs light in the visible light region as electromagnetic wave energy. That is, in the detection system 1 of the third modification, the energy releasing unit 20 includes, for example, a light emitting diode that outputs light in the visible light region, and the energy releasing unit 20 is capable of outputting visible light in a predetermined direction. In the detection system 1 of the third modification, the acquisition unit 32 acquires distribution information based on the sensing results of a plurality of visible light sensors arranged on at least one of the ceiling surface 101 and the floor surface 102. Each of the plurality of visible light sensors receives light in the visible light region and outputs an electric signal corresponding to the amount of light thus received. Each of the plurality of visible light sensors is embodied by, for example, a light receiving diode that is sensitive to light in the visible light region.

[0096] In the detection system 1 of the third modification as well, in a state in which the energy releasing unit 20 outputs visible light in a predetermined direction, the acquisition unit 32 acquires first distribution information indicating the distribution of light in the visible light region on the ceiling surface 101 and second distribution information indicating the distribution of light in the visible light region on the floor surface 102, in a similar manner to the basic configuration and the first and second modifications.

[0097] Then, the detector 33 detects attachment position information related to the attachment position of the lighting device 10A and attachment direction information related to the attachment direction of the lighting device 10A based on the distribution information (the first and second distribution information) acquired by the acquisition unit 32. The method for determining the attachment position and the attachment direction of the lighting device 10A with the detector 33 is similar to the method described in the basic configuration and the first and second modifications, and thus the description thereof is omitted.

[0098] Note that when the energy releasing unit 20 outputs visible light in a predetermined direction, the acquisition unit 32 preferably acquires distribution information based on the outputs of the visible light sensors in a state in which an opening (such as a window or the like) of the room 100 is closed with, for example, a curtain or a blind, and lighting devices arranged in the room 100 are turned off.

[0099] Further, when the environmental control device 10 is the lighting device 10A, the energy releasing unit 20 that outputs visible light in a predetermined direction can also be used as the light source 131 of the lighting device 10A.

[0100] Further, in the third modification example, the sensor unit 40 is not limited to a unit including a plurality of visible light sensors, but can be a visible light imager that is sensitive to light in a visible light region on at least one of the ceiling surface 101 and the floor surface 102 and is capable of capturing a visible light image. That is, the acquisition unit 32 can acquire the distribution information on at least one of the ceiling surface 101 and the floor surface 102 based on an image captured by the visible light imager that is sensitive to light in the visible light region. As compared with a case where the acquisition unit 32 acquires the distribution information based on output signals of a plurality of visible light sensors, in a case where the distribution information is acquired from an image captured by the visible light imager, it is possible to easily perform processing for acquiring the distribution information.

[0101] (3.4) Fourth Modification Example Based on Figure 10 A detection system 1 according to the fourth modification example will be described.

[0102] When it is assumed that the environment control device 10 described in the basic configuration and the first to third modification examples is a first environment control device, the detection system 1 of the fourth modification example includes a second environment control device 50 in addition to the first environment control device 10. The second environment control device 50 controls an environment in the internal space 103 of the room 100. The acquisition unit 32 acquires the distribution information in a state where the second environment control device 50 controls so that the internal space 103 of the room 100 is in a predetermined state. Note that the detection system 1 of the fourth modification example is similar to the detection system 1 described in the basic configuration and the first to third modification examples except that the detection system 1 of the fourth modification example includes the second environment control device 50. Therefore, components common to those in the basic aspect and the first to third modification examples are denoted by the same reference numerals, and the description thereof is omitted.

[0103] The second environment control device 50 includes a functional unit 52 for controlling an environment in the internal space 103 of the room 100 and a control unit 51 for controlling the functional unit 52.

[0104] When the energy release unit 20 outputs electromagnetic waves having thermal radiation, the second environment control device 50 is, for example, preferably an air conditioning device for adjusting a temperature of the internal space 103 of the room 100, and it is enough that the functional unit 52 has a function of adjusting the temperature of the internal space 103 of the room 100.

[0105] In the detection system 1 of the fourth modification example, when the acquisition unit 32 acquires the distribution information, the air conditioning device as the second environment control device 50 performs a cooling operation so that the inside space of the room 100 has a second temperature lower than a first temperature as a temperature when the air conditioning device is off. In this state, the energy releasing unit 20 outputs the electromagnetic wave having the thermal radiation in the predetermined direction, and the acquisition unit 32 acquires the distribution information.

[0106] As described above, since the energy releasing unit 20 outputs the electromagnetic wave having the thermal radiation in a state where the second environment control device 50 performs control so that the inside space 103 of the room 100 has the second temperature lower than the first temperature, the acquisition unit 32 can easily detect the region irradiated with the electromagnetic wave having the thermal radiation from the energy releasing unit 20, and can more accurately detect the attachment position information and the attachment direction information related to the first environment control device 10.

[0107] Note that the second environment control device 50 is not limited to the air conditioning device, and can correspondingly change a control object of the second environment control device 50 depending on the electromagnetic wave energy output from the energy releasing unit 20. For example, when the energy releasing unit 20 outputs visible light, it is enough that the second environment control device 50 has a function of controlling brightness in the inside space 103 of the room 100. For example, it is enough that the functional unit 52 of the second environment control device 50 has a function of electrically opening and closing, for example, a curtain or a blind installed at a window of the room 100. In this case, it is enough that the acquisition unit 32 acquires the distribution information in a state where the window is covered with, for example, the curtain or the blind electrically driven with the functional unit 52 of the second environment control device 50, which facilitates detection of the region that is part of the ceiling surface 101 or the floor surface 102 and is irradiated with the visible light from the energy releasing unit 20.

[0108] (3.5) Fifth Modification Example Based on Figures 11 to 14 A detection system 1 according to the fifth modification example will be described.

[0109] The detection system 1 according to the fifth modification example is different from the basic configuration and the first to fourth modification examples in that the environment control device 10 is an air conditioning device 10B installed on the ceiling surface 101. The air conditioning device 10B has a configuration similar to that of the lighting device 10A except that the functional unit 12 of the air conditioning device 10B provides a function different from that of the functional unit 12 of the lighting device 10A, and thus components common to those of the lighting device 10A are denoted by the same reference numerals, and the description thereof is omitted.

[0110] The air conditioning device 10B includes a functional unit 12 for providing a function of blowing warm air or cold air. The functional unit 12 of the air conditioning device 10B includes, for example, a heat exchanger for heating or cooling air and a blower fan for generating an air current. Further, the air conditioning device 10B includes a housing 120 fixed to the ceiling surface 101 in a state in which a portion of the housing 120 is embedded in the ceiling surface 101. The housing 120 has a substantially square shape when viewed from below, and has air vents 121 to 124 along four sides of the housing 120. Further, the air conditioning device 10B has a damper for controlling the direction of air blown through each of the four vents 121 to 124. Note that the reference direction of the housing 120 of the air conditioning device 10B is, for example, a direction parallel to two sides on which the vents 121 and 122 are provided.

[0111] Here, the air conditioning device 10B as the environmental control device 10 includes an energy releasing unit 20 capable of outputting an air current of a predetermined temperature in a predetermined direction. In this regard, the functional unit 12 of the air conditioning device 10B also functions as the energy releasing unit 20, and the acquisition section 32 performs the acquisition process in a state in which the air conditioning device 10B outputs an air current of a second temperature or an air current of a third temperature. The second temperature is a temperature lower than the first temperature of the internal space 103 in a state in which the air conditioning device 10B is off by a predetermined number of degrees. The third temperature is a temperature higher than the first temperature by a predetermined number of degrees. Since the energy releasing unit 20 is embodied by the functional unit 12 of the air conditioning device 10B, and the energy releasing unit 20 also functions as the functional unit 12, there is an advantage that the energy releasing unit 20 does not necessarily have to be provided in addition to the functional unit 12.

[0112] The air conditioning device 10B is capable of outputting an air current of a predetermined temperature (second temperature or third temperature) in a predetermined direction. For example, the air conditioning device 10B can output an air current of a predetermined temperature vertically downward from the four vents 121 to 124. The air current of a predetermined temperature output vertically downward from the air conditioning device 10B is output to an elliptical region B11 (see Figure 11 and 12 ) in which the center of the ellipse corresponds to the center of the housing 120.

[0113] Further, when an air current of a predetermined temperature is output to the right from the vent 121 along the right side of the air conditioning device 10B, the air current output from the vent 121 is output to a region B12 (see Figure 11 and Figure 13). Here, the center position P12 of the region B12 is located to the right of the center position of the housing 120. Note that the center position of the housing 120 is the center position on the lower surface of the housing 120, and is the center position in the left / right direction and the front / back direction.

[0114] Further, when outputting the airflow of the predetermined temperature to the left from the air vent 122 along the left side of the air conditioning device 10B, the airflow output from the air vent 122 is output to a region B13 (see Figure 11 and Figure 14 ) that is a part of the ceiling surface 101 and is on the left side of the housing 120.

[0115] Here, the air vent direction when the air conditioning device 10B blows the airflow to the right from the air vent 121 and the air vent direction when the air conditioning device 10B blows the airflow to the left from the air vent 122 point to directions opposite to each other with respect to the center position of the air conditioning device 10B. Therefore, the region B12 to which the airflow output to the right from the air conditioning device 10B is blown and the region B13 to which the airflow output to the left from the air conditioning device 10B is blown are regions symmetrical with respect to a straight line that passes through the center position of the housing 120 and is parallel to the reference direction of the housing 120.

[0116] Here, in order to detect the attachment position of the air conditioning device 10B with the detection system 1 of the fifth modified example, the user gives an operation to the operation unit 13 of the air conditioning device 10B so that the air conditioning device 10B outputs the airflow of the predetermined temperature vertically downward. In a state where the air conditioning device 10B outputs the airflow of the predetermined temperature vertically downward, the acquisition unit 32 acquires the sensing results from the plurality of temperature sensors 41 installed on the floor surface 102. The acquisition unit 32 acquires the temperature distribution on the floor surface 102 as the second distribution information on the basis of the sensing results acquired from the plurality of temperature sensors 41 installed on the floor surface 102.

[0117] When the acquisition processing of the acquisition unit 32 ends, the detector 33 performs processing for detecting the attachment position information related to the attachment position of the air conditioning device 10B on the basis of the second distribution information acquired by the acquisition unit 32. The detector 33 determines the region B11 (see Figure 11 and Figure 12 ) that is a part of the floor surface 102 and to which the airflow of the predetermined temperature is blown from the second distribution information acquired by the acquisition unit 32, and the detector 33 determines the center position of the region B11 as the position P11 directly below the air conditioning device 10B. Then, the detector 33 determines the position coordinates of the position directly above the position P11 on the ceiling surface 101 as the attachment position information related to the attachment position of the air conditioning device 10B.

[0118] Further, in order for the detection system 1 of the fifth modification example to detect the attachment position and the attachment direction of the air conditioning device 10B, the acquisition unit 32 performs the acquisition process in each of a state in which the air conditioning device 10B outputs an airflow of a predetermined temperature to the right and a state in which the air conditioning device 10B outputs an airflow of a predetermined temperature to the left.

[0119] First, the user gives an operation to the operation unit 13 of the air conditioning device 10B, thereby causing an airflow of a predetermined temperature to be output to the right from the vent 121 of the air conditioning device 10B. In a state in which the air conditioning device 10B outputs an airflow of a predetermined temperature to the right from the vent 121, the acquisition unit 32 acquires a sensing result from the plurality of temperature sensors 41 installed on the ceiling surface 101. The acquisition unit 32 acquires first distribution information related to a temperature distribution on the ceiling surface 101 on the basis of the sensing result acquired from the plurality of temperature sensors 41 installed on the ceiling surface 101.

[0120] Then, the user gives an operation to the operation unit 13 of the air conditioning device 10B, thereby causing an airflow of a predetermined temperature to be output to the left from the vent 122 of the air conditioning device 10B. In a state in which the air conditioning device 10B outputs an airflow of a predetermined temperature to the left from the vent 122, the acquisition unit 32 acquires a sensing result from the plurality of temperature sensors 41 installed on the ceiling surface 101. The acquisition unit 32 acquires first distribution information related to a temperature distribution on the ceiling surface 101 on the basis of the sensing result acquired from the plurality of temperature sensors 41 installed on the ceiling surface 101.

[0121] When the acquisition unit 32 acquires the first distribution information in each of the state in which the air conditioning device 10B outputs an airflow of a predetermined temperature to the right and the state in which the air conditioning device 10B outputs an airflow of a predetermined temperature to the left, the detector 33 performs a process for detecting attachment position information related to the attachment position of the air conditioning device 10B and attachment direction information related to the attachment direction thereof on the basis of the first distribution information acquired by the acquisition unit 32. First, the detector 33 determines the position coordinates of the center position P12 (see Figure 11 and Figure 13 ) of the region B12 on the ceiling surface 101 to which an airflow of a predetermined temperature output from the air conditioning device 10B is blown on the basis of the first distribution information in the state in which the air conditioning device 10B outputs an airflow of a predetermined temperature to the right. Then, the detector 33 determines the position coordinates of the center position P13 (see Figure 11 and Figure 14the center position P12 and the center position P13, the detector 33 determines the position coordinates of the midpoint between the two center positions P12 and P13 as the position coordinates of the attachment position of the air conditioning device 10B. Further, the detector 33 determines a direction orthogonal to both of the line segment passing through the midpoint between the two center positions P12 and P13 and connecting the two center positions P12 and P13 and the normal line of the ceiling surface 101 as the direction in which the reference direction of the air conditioning device 10B is directed (attachment direction), and determines information (for example, vector information) representing this direction as attachment direction information.

[0122] As described above, also in the detection system 1 of the fifth modified example, the detector 33 can detect the attachment position information related to the attachment position of the air conditioning device 10B and the attachment direction information related to the attachment direction of the air conditioning device 10B.

[0123] (3.6) Sixth Modified Example Based on Figure 15 A detection system 1 according to the sixth modified example will be described.

[0124] The detection system 1 according to the sixth modified example is different from the detection system 1 of the fifth modified example in that the acquisition section 32 performs the acquisition process in each of the state in which the air conditioning device 10B outputs the airflow of the predetermined temperature vertically downward, the state in which the air conditioning device 10B outputs the airflow of the predetermined temperature obliquely downward to the right, and the state in which the air conditioning device 10B outputs the airflow of the predetermined temperature obliquely downward to the left. Note that the detection system 1 of the sixth modified example is similar to the detection system 1 of the fifth modified example except for the direction in which the air conditioning device 10B outputs the airflow of the predetermined temperature when the acquisition section 32 performs the acquisition process, and thus components common to the fifth modified example are denoted by the same reference numerals as in the fifth modified example, and the description thereof is omitted.

[0125] In the air conditioning device 10B of the sixth modified example, as shown in Figure 15 the acquisition section 32 performs the acquisition process in each of the state in which the air conditioning device 10B outputs the airflow of the predetermined temperature vertically downward, the state in which the air conditioning device 10B outputs the airflow of the predetermined temperature obliquely downward to the right, and the state in which the air conditioning device 10B outputs the airflow of the predetermined temperature obliquely downward to the left, and the detector 33 performs the detection process based on the distribution information acquired by the acquisition section 32. Note that the angle formed between the wind direction when the air conditioning device 10B outputs the airflow obliquely downward to the right and the direction of gravity and the angle formed between the wind direction when the air conditioning device 10B outputs the airflow obliquely downward to the left and the direction of gravity are set to the same angle.

[0126] Here, in order to detect the attachment position of the air conditioning device 10B by the detection system 1, the air conditioning device 10B outputs an airflow of a predetermined temperature vertically downward.

[0127] In a state where the air conditioning device 10B outputs an airflow of a predetermined temperature vertically downward, the acquisition unit 32 acquires the sensing results from the plurality of temperature sensors 41. The acquisition unit 32 acquires second distribution information related to the temperature distribution on the floor surface 102 on the basis of the sensing results acquired from the plurality of temperature sensors 41.

[0128] When the acquisition processing of the acquisition unit 32 ends, the detector 33 performs processing for detecting attachment position information related to the attachment position of the air conditioning device 10B on the basis of the second distribution information acquired by the acquisition unit 32. The detector 33 determines a region B11, which is a part of the floor surface 102 and to which an airflow of a predetermined temperature is output, from the second distribution information acquired by the acquisition unit 32, and the detector 33 determines a center position of the region B11 as a position P11 directly below the air conditioning device 10B. Note that the detector 33 determines a region in which the temperature is higher than or equal to a predetermined threshold temperature as the region B11 to which an airflow of a predetermined temperature is output. Then, the detector 33 determines position coordinates of a position on the ceiling surface 101 and directly above the position P11 as the attachment position information related to the attachment position of the air conditioning device 10B.

[0129] Further, in order to detect the attachment position information and the attachment direction information related to the air conditioning device 10B by the detection system 1 of the sixth modified example, the air conditioning device 10B outputs an airflow of a predetermined temperature obliquely downward to the right and obliquely downward to the left, respectively.

[0130] First, the user gives a switching operation to the operation unit 13 of the air conditioning device 10B so that an airflow of a predetermined temperature is output obliquely downward to the right, and then the operation unit 13 receives the switching operation given by the user, and the control unit 11 causes the air conditioning device 10B to output an airflow of a predetermined temperature obliquely downward to the right on the basis of a switching signal from the operation unit 13. In a state where the air conditioning device 10B outputs an airflow of a predetermined temperature obliquely downward to the right, the user gives an operation to the operation unit 35 to instruct acquisition processing, and then the acquisition unit 32 acquires sensing results from the plurality of temperature sensors 41. The acquisition unit 32 acquires second distribution information related to the temperature distribution on the floor surface 102 on the basis of the sensing results acquired from the plurality of temperature sensors 41.

[0131] Then, the user gives a switching operation to the operation unit 13 of the air conditioning device 10B such that the air current of the predetermined temperature is output to the left obliquely downward, and then the operation unit 13 receives the switching operation given by the user, and the control unit 11 causes the air conditioning device 10B to output the air current of the predetermined temperature to the left obliquely downward on the basis of the switching signal from the operation unit 13. In a state where the air conditioning device 10B outputs the air current of the predetermined temperature to the left obliquely downward, the user gives an operation to the operation unit 35 to instruct the acquisition processing, and then the acquisition unit 32 acquires the sensing results from the plurality of temperature sensors 41. The acquisition unit 32 acquires the second distribution information related to the temperature distribution on the floor surface 102 on the basis of the sensing results acquired from the plurality of temperature sensors 41.

[0132] When the acquisition unit 32 acquires the second distribution information in each of the state where the air conditioning device 10B outputs the air current of the predetermined temperature to the right obliquely downward and the state where the air conditioning device 10B outputs the air current of the predetermined temperature to the left obliquely downward, the detector 33 performs processing for detecting the attachment position information related to the attachment position of the air conditioning device 10B and the attachment direction information related to the attachment direction thereof on the basis of the second distribution information acquired by the acquisition unit 32.

[0133] First, the detector 33 determines the position coordinates of the center position P14 of the region B14 that is a part of the floor surface 102 and to which the air current is blown on the basis of the second distribution information in the state where the air conditioning device 10B outputs the air current of the predetermined temperature to the right obliquely downward. Then, the detector 33 determines the position coordinates of the center position P15 of the region B15 that is a part of the floor surface 102 and to which the air current is blown on the basis of the second distribution information in the state where the air conditioning device 10B outputs the air current of the predetermined temperature to the left obliquely downward.

[0134] Here, the angle formed between the wind direction when the air conditioning device 10B outputs the air current to the right obliquely downward and the direction of gravity and the angle formed between the wind direction when the air conditioning device 10B outputs the air current to the left obliquely downward and the direction of gravity are set to the same angle. Therefore, the two regions B14 and B15 are regions that are symmetrical with respect to a straight line that passes through a position directly below the center position of the air conditioning device 10B and that is parallel to the reference direction of the air conditioning device 10B.

[0135] Thus, when the position coordinates of the center positions P14 and P15 of the regions B14 and B15, respectively, are determined, the detector 33 calculates the position coordinates of the midpoint between the two center positions P14 and P15 to determine the position coordinates of the position directly above the midpoint on the ceiling surface 101 and between the center positions P14 and P15 as the position information related to the attachment position of the air conditioning device 10B. Further, the detector 33 determines a straight line that is orthogonal to both the line segment connecting the center positions P14 and P15 to each other and the normal line of the floor surface 102, and the detector 33 determines the direction extending along the straight line that is parallel to the above-mentioned determined straight line orthogonal to the line segment and the normal line as the attachment direction information related to the attachment direction of the housing 120.

[0136] As described above, also in the detection system 1 of the sixth modified example, the detector 33 can detect the attachment position information related to the attachment position of the air conditioning device 10B and the attachment direction information related to the attachment direction of the air conditioning device 10B.

[0137] Note that, in the fifth modified example and the sixth modified example, the sensor unit 40 includes a plurality of temperature sensors 41, but the sensor unit 40 can include a plurality of infrared imaging cameras 42 arranged on the ceiling surface 101 and the floor surface 102 in a similar manner to the second modified example (see FIG. 6). Figure 16 That is, the acquisition unit 32 can acquire the distribution information based on the sensing results of the plurality of infrared imaging cameras 42 arranged on the ceiling surface 101 and the floor surface 102.

[0138] Further, when the detector 33 detects the attachment position information and the attachment direction information related to the air conditioning device 10B based on the first distribution information related to the ceiling surface 101, it is sufficient that the sensor unit 40 includes only the infrared imaging camera 42 for photographing the ceiling surface 101 (see FIG. 6), and the infrared imaging camera 42 for photographing the floor surface 102 is optional. Figure 17

[0139] Further, in the fifth modified example and the sixth modified example, the sensor unit 40 can include an infrared detection sensor (such as an infrared array sensor or the like) capable of detecting the distribution of light in an infrared region on the ceiling surface 101 or the floor surface 102.

[0140] That is, it is sufficient that the sensor unit 40 includes a sensor capable of detecting the region blown by the airflow of a predetermined temperature output from the air conditioning device 10B, and the configuration of the sensor unit 40 can be modified accordingly.
