Description

Technical Field

[0001] The present disclosure relates to a sensing switch and a control program installed in a building.

Background Art

[0002] In the design of houses, it is important to block outside air and maintain the indoor temperature and humidity, and there is a demand for buildings that can achieve a comfortable living environment with warmth in winter and coolness in summer. In recent years, the Agency for Natural Resources and Energy has been recommending ZEH (net Zero Energy House) aiming at energy conservation. Along with this, higher airtightness and heat insulation of electrical equipment and wiring fixtures in buildings have been demanded.

[0003] Among the electrical equipment and wiring fixtures in a building, there is a heat ray sensing switch. The heat ray sensing switch determines whether a person is present within a specific detection range by detecting the heat rays radiated from the human body, and controls loads such as lighting fixtures according to the presence or absence of a person. In the case of a ceiling-embedded type heat ray sensing switch, it is common to perform the setting operation with a manual switch.

[0004] In the heat ray sensing switch disclosed in Patent Document 1, adjustment knobs 53a and 54a for adjusting the brightness threshold and the lighting holding time respectively, and an operation knob 55a for switching the operation mode of the control circuit are arranged on the lower surface of the device body 1 (see FIG. 1 of Patent Document 1). Insertion holes 11d and 11d and a square hole portion 11c for exposing the adjustment knobs 53a and 54a and the operation knob 55a are penetratingly provided in a plate 10 covering the lower surface of the device body 1.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, these adjustment components create gaps that connect to the ceiling space, reducing the airtightness of the building. Also, while it is common to cover knobs 53a, 54a, and 55a with covers to prevent easy operation, covering the sensor switch makes a flat design difficult and hinders the reduction in height. The aesthetic appeal is also reduced. Furthermore, providing knobs 53a, 54a, and 55a and covers increases the number of parts and increases costs.

[0007] This disclosure is made in light of these circumstances, and its purpose is to provide a highly airtight sensing switch. [Means for solving the problem]

[0008] To solve the above problems, a sensing switch according to one aspect of the present disclosure includes a sensing sensor unit that transmits radio waves, receives the reflected waves, and outputs sensing data, and a control unit that outputs a signal to a load based on the sensing data input from the sensing sensor unit. The control unit includes a motion detection unit that identifies the position, movement, or shape of a moving object present in the detection range based on the sensing data, and a setting adjustment unit that adjusts the settings of the sensing switch or the load based on the position, movement, or shape of the moving object identified by the motion detection unit.

[0009] Furthermore, any combination of the above components, as well as any conversion of the expressions of this disclosure between devices, systems, methods, computer programs, etc., are also valid forms of this disclosure. [Effects of the Invention]

[0010] According to this disclosure, a highly airtight sensing switch can be realized. [Brief explanation of the drawing]

[0011] [Figure 1] This is a front view of a ceiling-mounted sensing switch according to Comparative Example 1. [Figure 2]This is a front view of a wall-mounted sensing switch according to Comparative Example 2. [Figure 3] This is a front view of a ceiling-mounted sensing switch according to an embodiment. [Figure 4] This is a functional block diagram of a ceiling-mounted sensor switch according to an embodiment. [Figure 5] This figure shows an example of the selection items presented on the display surface of the annular plate of the device. [Figure 6] This figure shows an example of a conversion table for gesture operation according to the embodiment. [Figure 7] This figure shows the state after the ambient illuminance at which the brightness sensor operates has been changed from the setting state shown in Figure 5. [Figure 8] Figures 8(a)-(b) show the state of hand Ha used to operate a sensor switch embedded in the ceiling, and a first example of the 3D point cloud data of the hand detected by the sensor unit. [Figure 9] Figures 9(a)-(b) show the state of hand Ha used to operate a sensor switch embedded in the ceiling, and a second example of the 3D point cloud data of the hand detected by the sensor unit. [Figure 10] Figures 10(a)-(b) show the state of hand Ha used to operate a sensor switch embedded in the ceiling, and a third example of the 3D point cloud data of the hand detected by the sensor unit. [Figure 11] This diagram illustrates an example where a user changes the value of a setting item by making a circular gesture in the air with their index finger. [Modes for carrying out the invention]

[0012] Figure 1 is a front view of a ceiling-mounted sensor switch 1 according to Comparative Example 1. The sensor switch 1 according to Comparative Example 1 is installed on the ceiling of a toilet or the like. The body 1a of the sensor switch 1 is fixed in a mounting hole provided in the construction surface (in Comparative Example 1, the ceiling) with a portion of it embedded in the depth direction. The body 1a has an annular plate exposed from the construction surface and a cylindrical support column embedded in the construction surface, and the annular plate is fixed to the support column with a screw 1c. The sensor switch 1 is connected to a load and functions as an automatic switch that automatically turns on the load (in Comparative Example 1, a ventilation fan) when it detects human movement, and automatically turns off the load after a certain period of time.

[0013] A thermal sensor 10h is installed in the center of the annular plate of the device body 1a. The thermal sensor 10h has a beam-shaped detection range and sends a detection signal to the control circuit when it detects a change in the thermal level (for example, a temperature change of 3°C or more) within the detection range. Normally, when a person enters the detection range, the thermal level rises by 3°C or more. When the control circuit receives a detection signal from the thermal sensor 10h, it operates the ventilation fan. At the same time, the control circuit can also turn on the lighting fixture. When the control circuit no longer detects a person within the detection range, it stops the ventilation fan after a set operating hold time. If the lighting fixture was on, it also turns off.

[0014] Below the thermal sensor 10h on the annular plate of the device body 1a, there is an operation hold time adjustment knob 51 and an intermittent operation time adjustment knob 52. The user or installer (hereinafter, when both are referred to collectively, the user, etc.) can adjust the position of the operation hold time adjustment knob 51 to set the duration of operation of the ventilation fan after it starts operating triggered by human detection. In the example shown in Figure 1, it can be set in the range of 10 seconds to 30 minutes. The user, etc. can also set the ventilation fan to be permanently off by adjusting the position of the operation hold time adjustment knob 51 to "off". Alternatively, the ventilation fan can be set to be permanently on by adjusting the position of the operation hold time adjustment knob 51 to "continuous on".

[0015] Users and the like can operate the ventilation fan in intermittent operation by adjusting the position of the intermittent operation time adjustment knob 52 to a position other than "off". In intermittent operation, the ventilation fan operates every certain period (for example, one hour) regardless of whether a person is detected or not. Users and the like can set the operation time during intermittent operation by adjusting the position of the intermittent operation time adjustment knob 52. In the example shown in FIG. 1, it can be set within the range from 30 seconds to 50 minutes.

[0016] After adjusting the operation holding time or the intermittent operation time, users and the like cover the cover plate 10b on the annular plate of the body 1a. In the detection switch 1 according to Comparative Example 1, due to the heights of the knobs 51 and 52, the cover plate 10b has a shape with a certain bulge with respect to the ceiling surface, and it is difficult to achieve a flat design with respect to the ceiling surface.

[0017] FIG. 2 is a front view of the wall-mounted detection switch 1 according to Comparative Example 2. The detection switch 1 according to Comparative Example 2 is installed on the inner wall of a building or the like. The body 1a of the detection switch 1 is fixed in a state where a part in the depth direction is embedded in a mounting hole provided in the construction surface (in Comparative Example 2, the side wall). The body 1a has a rectangular plate exposed from the construction surface and a body embedded in the construction surface. The detection switch 1 is connected to a load and has a function as an automatic switch that automatically turns on the load (in Comparative Example 2, a lighting fixture) when detecting a human movement or the like and automatically turns off the load after a certain period.

[0018] A pyroelectric sensor 10h and a brightness sensor (illuminance sensor) are installed below the rectangular plate of the body 1a. The pyroelectric sensor 10h sends a detection signal to the control circuit when detecting a change in the pyroelectric level (for example, a temperature change of more than +3°C) within the detection range. The brightness sensor measures the ambient illuminance and sends the measured illuminance to the control circuit.

[0019] A manual switch 54 is installed above the thermal sensor 10h on the rectangular plate of the device body 1a. Users can set the operating mode by switching the position of the manual switch 54 between "Off," "Automatic," and "Continuous On." For example, adjusting the manual switch 54 to the left position selects "Off," adjusting it to the center position selects "Automatic," and adjusting it to the right position selects "Continuous On." When "Off" is selected, the lighting fixture is set to a mode where it is always off. When "Automatic" is selected, the lighting fixture is set to an automatic mode where it automatically turns on when a person is detected. When "Continuous On" is selected, the lighting fixture is set to a mode where it is always on.

[0020] Above the manual switch 54 on the rectangular plate of the device body 1a, there is an operation hold time adjustment knob 51 and a brightness sensor adjustment knob 53. By adjusting the position of the operation hold time adjustment knob 51, the user can set the duration for which the lighting fixture remains lit after it is triggered by human detection in automatic mode. In the example shown in Figure 2, the duration can be set in the range of 10 seconds to 30 minutes.

[0021] Users can set the ambient illuminance at which the brightness sensor operates in automatic mode by adjusting the position of the brightness sensor adjustment knob 53. In the example shown in Figure 2, the operating ambient illuminance can be set within the range from "dim" (5 lux) to "bright" (200 lux). The control circuit turns on the lighting fixture when a person enters the detection range while the ambient illuminance measured by the brightness sensor is lower (dimer) than the set operating ambient illuminance. If the measured ambient illuminance is higher (brighter) than the set operating ambient illuminance, the lighting fixture will not turn on even if a person is detected. Users can also set the lighting fixture to turn on when a person enters the detection range, regardless of the ambient brightness, by adjusting the position of the brightness sensor adjustment knob 53 to "off".

[0022] After adjusting the operating hold time or brightness sensor, the user closes the door 1d that conceals the knobs 51 and 53. In the sensing switch 1 according to Comparative Example 2, the presence of a manual switch 54 reduces the aesthetic appeal.

[0023] Figure 3 is a front view of a ceiling-mounted sensor switch 1 according to an embodiment. The sensor switch 1 body 1a according to the embodiment is fixed in a mounting hole provided in the construction surface (ceiling in this embodiment) with a portion of it embedded in the depth direction. Compared to the sensor switch 1 according to Comparative Example 1 shown in Figure 1, no physical components, including the operating knob, are placed on the annular plate of the body 1a that is exposed from the construction surface. The annular plate has a flat shape without irregularities, and the protrusion from the ceiling surface is minimized.

[0024] In the sensor switch 1 according to this embodiment, a millimeter-wave radio wave sensor is used as the sensor for detecting people, instead of a thermal sensor. The radio wave sensor is installed on the back side (above the ceiling) of the annular plate. A brightness sensor is also installed near the radio wave sensor. The sensor switch 1 is operated by gesture.

[0025] Figure 4 is a functional block diagram of a ceiling-mounted sensing switch 1 according to an embodiment. The sensing switch 1 according to the embodiment comprises a sensing sensor unit 15, a control unit 20, a storage unit 30, and a display unit 40. The sensing sensor unit 15 transmits 60GHz band millimeter waves, receives the reflected waves, generates 3D point cloud data, and outputs it to the control unit 20 as detection data.

[0026] The detection sensor unit 15 in this embodiment includes a synthesizer, one transmitting antenna, three receiving antennas, a mixer, an A / D converter, and a DSP (Digital Signal Processing). The synthesizer generates a chirp signal whose frequency changes linearly over time using the FMCW (Frequency Modulated Continuous Wave) method. The transmitting antenna transmits the chirp signal generated by the synthesizer as a transmission wave towards the detection range. Each receiving antenna receives the chirp signal reflected by objects within the detection range as a reflected wave. The reflected wave has a delay proportional to the distance relative to the transmitted wave.

[0027] The mixer generates an IF signal by combining the reflected wave and the transmitted wave. The frequency of the generated IF signal decreases as the object is closer to the detection sensor unit 15, and increases as it is farther away. The A / D converter converts the IF signal generated by the mixer into a digital value.

[0028] The DSP converts the IF signal, which has been converted to a digital value, into a frequency domain signal to generate the distance to the object, the object's velocity, and the angle to the object. For example, the DSP performs an FFT (Fast Fourier Transformation) (distance FFT) on the IF signal to generate the frequency spectrum of the IF signal. The distance to the object is calculated based on the peaks in the frequency spectrum. If multiple objects are present in the detection range, multiple peaks will appear.

[0029] The DSP calculates the velocity of an object by performing a further FFT (Doppler FFT) on the output obtained after multiple distance FFT processing from the reflected waves of multiple chirp signals transmitted at regular time intervals. The frequency spectrum is obtained by accumulating the phase changes of the peaks of the IF signal, and the velocity of the object is calculated based on the peaks of this frequency spectrum. If multiple moving objects are present in the detection range, multiple peaks will appear.

[0030] The DSP calculates the angle of an object by performing an FFT (angle FFT) on the output after the Doppler FFT of multiple chirp signals received by multiple receiving antennas. A phase difference occurs in the peaks of the frequency spectrum due to the difference in distance from the object to each receiving antenna. The angle of arrival (AoA) is calculated using this phase difference of the peaks between the receiving antennas.

[0031] The detection sensor unit 15 generates 3D point cloud data based on the distance and angle to the object, which are determined by the reflected waves received by the three receiving antennas, and outputs the generated 3D point cloud data to the control unit 20. If the object is moving, the detection sensor unit 15 outputs the 3D point cloud data, which changes in real time, to the control unit 20.

[0032] The control unit 20 outputs a signal to the load based on the 3D point cloud data input from the detection sensor unit 15. In this embodiment, a lighting fixture 2 is assumed to be the load. However, the load is not limited to a lighting fixture 2 and may be a ventilation fan, air conditioner, escalator, security equipment, etc.

[0033] The control unit 20 includes a motion detection unit 21, a setting adjustment unit 22, a signal transmission unit 23, and a guide control unit 24. The control unit 13 can be realized through the collaboration of hardware and software resources, or solely through hardware resources. Hardware resources that can be used include analog circuits, logic circuits, microcontrollers, DSPs, ROMs, RAMs, GPUs, ASICs, FPGAs, and other LSIs. Software resources that can be used include programs such as firmware.

[0034] The storage unit 30 includes non-volatile memory such as EEPROM (Electrically Erasable Programmable Read-Only Memory) or NAND flash memory, and holds a conversion table 30a for gesture operation. If the capacity of the conversion table 30a is small, the conversion table 30a may be stored in ROM within the control unit 20. Alternatively, it may be pre-written into the source code of the program executed by the control unit 20. In these cases, the storage unit 30 can be omitted.

[0035] The motion detection unit 21 detects whether or not a moving object exists within the detection range based on the 3D point cloud data input from the detection sensor unit 15. Even if an object is detected within the detection range, if it is stationary, that object is ignored. The motion detection unit 21 can determine whether the detected object is moving or stationary by comparing the 3D point cloud data in the time direction.

[0036] The motion detection unit 21 identifies the position, movement, or shape of a moving object when it is detected within its detection range. The setting adjustment unit 22 can adjust the settings of the sensing switch 1 or lighting fixture 2 based on the position, movement, or shape of the moving object identified by the motion detection unit 21.

[0037] The setting adjustment unit 22 switches the sensing switch 1 to construction mode when the motion detection unit 21 detects the approach of a moving object to a specific position, a specific movement of a moving object, or a specific shape of a moving object. For example, the setting adjustment unit 22 switches to construction mode when a moving object such as a finger or a rod-shaped indicator approaches the detection sensor unit 15 within a predetermined distance (e.g., 10 cm). For example, the setting adjustment unit 22 switches to construction mode when the point located at the top of the Z axis in the 3D point cloud data is located within 10 cm of the detection sensor unit 15. When the system switches to construction mode, the guide control unit 24 generates a guide corresponding to the selected item on the display surface on the annular plate of the device body 1a that is exposed from the mounting hole on the construction surface.

[0038] Figure 5 shows an example of the selection items presented on the display surface of the annular plate of the device body 1a. In the example shown in Figure 5, in installation mode, the operation hold time, during which the lighting fixture 2 remains lit after a person is detected, and the operating ambient illuminance at which the brightness sensor operates can be set. In the example shown in Figure 5, the operation hold time can be selected from 1 minute, 5 minutes, 10 minutes, and 30 minutes, and the operating ambient illuminance can be selected from 10 lx, 50 lx, 100 lx, and 200 lx. The annular plate is divided into eight sections in the circumferential direction, with four options for the operation hold time assigned to the four upper, lower, left, and right regions, and four options for the operating ambient illuminance assigned to the four diagonal regions.

[0039] Specifically, the left area of ​​the ring plate has the characters "1 minute" printed on it and the first LED 40a is embedded there. The top area of ​​the ring plate has the characters "5 minutes" printed on it and the second LED 40b is embedded there. The right area of ​​the ring plate has the characters "10 minutes" printed on it and the third LED 40c is embedded there. The bottom area of ​​the ring plate has the characters "30 minutes" printed on it and the fourth LED 40d is embedded there. The upper right area of ​​the ring plate has the characters "10lx" printed on it and the fifth LED 40e is embedded there. The lower right area of ​​the ring plate has the characters "50lx" printed on it and the sixth LED 40f is embedded there. The lower left area of ​​the ring plate has the characters "100lx" printed on it and the seventh LED 40g is embedded there. The upper left area of ​​the ring plate has the characters "200lx" printed on it and the eighth LED 40h is embedded there.

[0040] When the system switches to construction mode, the guide control unit 24 illuminates the LEDs corresponding to the current settings for the operation hold time and ambient illuminance. In the example shown in Figure 5, the operation hold time is set to 5 minutes and the ambient illuminance is set to 50 lx, so the guide control unit 24 illuminates the second LED 40b and the sixth LED 40f. In normal mode, which is not construction mode, the first LED 40a to the eighth LED 40h are all turned off.

[0041] The gesture operation conversion table 30a stores multiple selection items and multiple positions linked together. In this embodiment, each position linked to each selection item is defined as a space on a three-dimensional coordinate system.

[0042] Figure 6 shows an example of a conversion table 30a for gesture operation according to the embodiment. For each of the four selectable options for operation hold time (1 minute, 5 minutes, 10 minutes, 30 minutes), specific spaces extending vertically towards the floor from the left, upper, lower, and right regions on the XY plane of the annular plate are associated. For each of the four selectable options for ambient illuminance of the brightness sensor (10 lx, 50 lx, 100 lx, 200 lx), specific spaces extending vertically towards the floor from the upper right region, lower right region, lower left region, and upper left region on the XY plane of the annular plate are associated.

[0043] In construction mode, when a representative point of the 3D point cloud data input from the detection sensor unit 15 enters one of the specific spaces defined in the conversion table 30a, the setting adjustment unit 22 changes the setting of the lighting fixture 2 to the value of the selected item associated with that specific space.

[0044] Figure 7 shows the state after the ambient illuminance operating the brightness sensor has been changed from the setting state shown in Figure 5. When a user's hand Ha enters a specific space in the lower left region of the annular plate, the setting adjustment unit 22 changes the ambient illuminance operating the brightness sensor from 50 lx to 100 lx. The guide control unit 24 turns off the 6th LED 40f and turns on the 7th LED 40g in accordance with the change in the ambient illuminance setting of the brightness sensor. This allows the user to confirm that the change in the ambient illuminance setting of the brightness sensor has been completed.

[0045] The examples of selection items shown in Figures 5 and 7 are just examples, and other examples may be used. For example, the text portions of "1 minute," "5 minutes," "10 minutes," "30 minutes," "10 lx," "50 lx," "100 lx," and "200 lx" may be made of a light-transmitting material, and the first LED 40a to the eighth LED 40h may be installed separately on the back of each text portion. In this case, when the guide control unit 24 lights up a specific LED, the text corresponding to that LED lights up, making it visible to the user. When the LED is off, the user cannot see the text.

[0046] Furthermore, a display (for example, an organic EL display or a liquid crystal display) may be installed on the display surface of the annular plate of the device body 1a. In that case, the guide control unit 24 can display guidance for changing settings on the display in the installation mode.

[0047] The signal transmission unit 23 can transmit a control signal containing the setting information determined by the setting adjustment unit 22 to a device that is linked with the sensing switch 1. For example, the signal transmission unit 23 can transmit a control signal containing the setting information to the master or slave unit of the sensing switch 1 that is linked with the sensing switch 1. If a controller is installed on the lighting fixture 2, the signal transmission unit 23 can transmit a control signal containing the setting information to the controller. Alternatively, the sensing switch 1 may directly drive the lighting fixture 2. In the case where the sensing switch 1 and the lighting fixture 2 are in a 1:1 closed relationship and the sensing switch 1 directly drives the lighting fixture 2, the signal transmission unit 23 can be omitted.

[0048] Figures 8(a) and 8(b) show the state of hand Ha for operating the sensing switch 1 embedded in the ceiling, and a first example of 3D point cloud data of hand Ha detected by the sensing sensor unit 15. Point C0 (x=0, y=0, z=0) in the coordinate space shown in Figure 8(b) represents the center coordinates of the surface of the sensing sensor unit 15. The Z axis represents the height direction of the building, and z=0 represents the height of the sensing sensor unit 15 from the floor. The example shown in Figure 8(a) shows the state in which the user brings the index finger of hand Ha close to the center of the surface of the sensing sensor unit 15 until it is almost in contact.

[0049] Figures 9(a) and 9(b) show the state of hand Ha for operating the sensing switch 1 embedded in the ceiling, and a second example of 3D point cloud data of hand Ha detected by the sensing sensor unit 15. The state shown in Figure 9(a) shows the state where the user's hand Ha is extended towards the sensing switch 1, as shown in Figure 8(a), but has been retracted and is away from the sensing switch 1. The 3D point cloud data shown in Figure 9(b) has shifted more in the negative direction (towards the floor) along the Z axis than the 3D point cloud data shown in Figure 8(b).

[0050] Figures 10(a) and 10(b) show the state of hand Ha for operating the sensing switch 1 embedded in the ceiling, and a third example of the 3D point cloud data of hand Ha detected by the sensing sensor unit 15. The coordinate space shown in Figure 10(b) is drawn with the Z axis in the depth direction and is drawn from a viewpoint looking down from the ceiling to the floor. The example shown in Figure 10(a) shows the state in which the user's index finger of hand Ha is pressed against the right side of the sensing sensor unit 15 toward the ceiling surface.

[0051] In construction mode, the setting adjustment unit 22 recognizes that an operation to select an item associated with a specific space has been performed when a representative point of the 3D point cloud data input from the detection sensor unit 15 enters one of the specific spaces defined in the gesture operation conversion table 30a. The representative point may be set, for example, to the point closest to the detection sensor unit 15 in the Z-axis direction, or it may be set to the average value or median of a predetermined number of points close to the detection sensor unit 15 in the Z-axis direction.

[0052] In the explanation so far, a conversion table 30a for gesture operation was used, which linked multiple selection items with multiple specific spaces. However, a conversion table 30a that links multiple selection items with the movement of a moving object may also be used as the conversion table 30a for gesture operation. The movement of a moving object may be, for example, the movement of a person's hand. Hand movements may include, for example, movements that draw a circle in the air, movements that draw an "X" in the air, movements that draw a triangle in the air, etc.

[0053] The motion detection unit 21 tracks the trajectory of a representative point in the 3D point cloud data input from the detection sensor unit 15 to identify the movement of the moving object. In construction mode, the setting adjustment unit 22 recognizes that an operation has been performed to select the selection item associated with the selection item corresponding to the movement of the moving object if the movement of the moving object identified by the motion detection unit 21 corresponds to one of the multiple movements of the moving object defined in the conversion table 30a.

[0054] Figure 11 shows an example of a user changing the value of a setting item by making a gesture of drawing a circle in the air with the index finger of hand Ha. For example, the motion hold time may be adjusted by drawing a clockwise circle in the air, and the ambient illuminance may be adjusted by drawing a counterclockwise circle. The values ​​of the motion hold time or ambient illuminance may be set to be finely adjustable. For example, the angle of movement of the finger drawing a clockwise circle (0 to 360°) may be associated with the motion hold time (0 to 30 minutes), and the motion hold time may be set to increment by 1 minute for every 12° increase in angle.

[0055] Alternatively, a conversion table 30a linking multiple selection items with the shape of a moving object may be used as the conversion table 30a for gesture operation. The shape of the moving object may be, for example, a pose of a human hand. Hand poses may include, for example, a fist, scissors, paper, a pose with one finger raised, a pose with three fingers raised, a pose with four fingers raised, etc.

[0056] The motion detection unit 21 converts the 3D point cloud data input from the detection sensor unit 15 into a 3D model and then into mesh data or surface data. The motion detection unit 21 identifies the shape of the moving object by performing pattern recognition on the converted mesh data or surface data. In construction mode, if the shape of the moving object identified by the motion detection unit 21 corresponds to one of the multiple shapes of moving objects defined in the conversion table 30a, the setting adjustment unit 22 recognizes that an operation has been performed to select the selection item associated with the selection item corresponding to the shape of the moving object.

[0057] Alternatively, a learning model for each gesture can be generated by pre-training a machine learning model using a large number of 3D point cloud data of each gesture for human operation as training data and each selection item as training data. In this case, a transformation table 30a for gesture operation is generated, which links the parameters of the learning models of multiple selection items and multiple gestures.

[0058] The motion detection unit 21 inputs the 3D point cloud data received from the detection sensor unit 15 into the learning model to generate a parameter set for the 3D point cloud data. The setting adjustment unit 22 refers to the conversion table 30a and recognizes that an operation has been performed to select the selection item associated with the parameter set that most closely approximates the generated parameter set for the 3D point cloud data.

[0059] Alternatively, a classifier for each gesture can be generated using machine learning. Using machine learning-generated models and classifiers enables the recognition of more complex gestures.

[0060] The setting adjustment unit 22 terminates the construction mode if, for example, a moving object such as a hand or a pointing tool moves more than a predetermined distance (e.g., 10 cm) away from the detection sensor unit 15. Alternatively, the transition to or termination of the construction mode may be performed by hand posture or movement.

[0061] In normal mode, the motion detection unit 21 outputs a detection signal to the signal transmission unit 23 if the position, movement, or shape of a motion detected within the detection range does not correspond to an operation that would transition to the installation mode. The signal transmission unit 23 transmits a lighting instruction signal to the controller of the lighting fixture 2. However, if the illuminance input from the brightness sensor is higher than the set ambient illuminance for operation, the signal transmission unit 23 does not transmit a lighting instruction signal. When the controller of the lighting fixture 2 receives a lighting instruction signal from the signal transmission unit 23, it turns on the lighting fixture 2.

[0062] After the signal transmission unit 23 transmits a light-on instruction signal and the set operation hold time has elapsed, it transmits a light-off instruction signal to the controller of the lighting fixture 2. When the controller of the lighting fixture 2 receives the light-off instruction signal, it turns off the lighting fixture 2.

[0063] Alternatively, a learning model of human intrusion behavior can be generated by pre-training a large amount of 3D point cloud data of human intrusion behavior into the detection range. In this case, the motion detection unit 21 can detect only humans who intrude into the detection range among the motion objects detected within the detection range. The signal transmission unit 23 sends a lighting instruction signal to the controller of the lighting fixture 2 only when a person enters the detection range. In this case, it is possible to reduce the number of times the lighting fixture 2 is turned on unnecessarily.

[0064] As explained above, this embodiment allows for the removal of the physical switch from the sensing switch 1, eliminating the gap caused by the physical switch. Therefore, the airtightness and thermal insulation of the building are improved. It also contributes to the realization of a ZEH (Zero Energy House). Furthermore, by removing the physical switch, the surface of the ring plate can be made flat, improving its aesthetic appeal. In addition, since the design related to the physical switch is unnecessary, it contributes to cost reduction and shorter delivery times.

[0065] The present disclosure has been explained above based on examples. These examples are illustrative, and it will be understood by those skilled in the art that various modifications are possible in combinations of their components and processing steps, and that such modifications are also within the scope of the present disclosure.

[0066] Figure 5 illustrates an example where the operating hold time for the lighting fixture 2 to remain lit and the ambient illuminance level at which the brightness sensor operates are presented simultaneously. In this regard, the system may also be configured to sequentially switch between setting items using a predetermined gesture, presenting the selection options for each setting item. The setting items may also include the dimming level.

[0067] In the above embodiment, an example using a 60GHz millimeter-wave sensor was shown, but millimeter-wave sensors in the 24GHz, 76GHz, 79GHz, or 94GHz bands may also be used. Alternatively, LiDAR (Light Detection and Ranging) may be used instead of a millimeter-wave sensor.
