Description

[Technical Field]

[0001] SUMMARY OF THE INVENTION The disclosed embodiments relate to a water discharge control system and a control system. [Background technology]

[0002] In recent years, with the development of information processing technology, sensors have made it possible for people to use the functions of devices without operating physical switches. In particular, technologies for detecting and recognizing devices by extracting features from information obtained by sensors have made remarkable advances. For example, a technology has been provided that discharges water at an adjusted temperature depending on the situation based on an image captured by a camera (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7330074 Summary of the Invention [Problem to be solved by the invention]

[0004] However, there is room for improvement in the above-mentioned conventional technologies. For example, to determine a situation from sensor information (detection information) such as images captured by a camera, it is necessary to use technologies such as AI (Artificial Intelligence) to extract features and make judgments based on the sensor information. The power consumption required for such processing is greater than that required for conventional control without using technologies such as AI. Furthermore, if a physical switch is not used when using plumbing equipment, the sensor must be constantly running, increasing power consumption. Therefore, there is a need to suppress the increase in power consumption in the control of plumbing equipment, such as water discharge and stop control.

[0005] The disclosed embodiments aim to provide a water discharge control system and a control system that suppress an increase in power consumption. [Means for solving the problem]

[0006] A water discharge control system according to one aspect of the embodiment comprises a water discharge unit, a detection unit that detects at least the water discharge area, and a control unit that performs at least one of determining the presence or absence of an object to be detected or extracting characteristic information about the object based on the detection results of the detection unit, and controls the water discharge state from the water discharge unit based on the results of the determination or extraction, and is characterized by having a power saving mode that reduces power consumption in the control unit, and a water discharge control mode that increases power consumption in the control unit more than in the power saving mode and causes the control unit to discharge water from the water discharge unit based on the detection results of the detection unit.

[0007] According to one aspect of the embodiment, the water discharge control system has a power saving mode that reduces power consumption in the control unit and a water discharge control mode in which the power consumption in the control unit is increased compared to the power saving mode and the control unit discharges water from the water discharge unit based on the detection result of the detection unit, thereby enabling control using the power saving mode. Therefore, the water discharge control system can suppress increases in power consumption. For example, the water discharge control system has a normal water discharge control mode and a power saving mode that consumes less power than the normal water discharge control mode, and can suppress power consumption by increasing power consumption only when necessary and saving power at other times.

[0008] A water discharge control system according to one aspect of the embodiment transitions to the power saving mode in response to the absence of the detected object continuing for a predetermined period of time or more in the water discharge control mode.

[0009] According to one aspect of the embodiment, the water discharge control system can transition to the power-saving mode at an appropriate time by transitioning to the power-saving mode when a state in which no object is detected continues for a predetermined period of time or more. Therefore, the water discharge control system can suppress an increase in power consumption. For example, if no object is detected within the detection range for a certain period of time, the water discharge control system can determine that the space around the faucet is not being used and transition to the power-saving mode.

[0010] In one aspect of the embodiment, the water discharge control system transitions to the power saving mode in response to the control unit acquiring predetermined first operation information in the water discharge control mode.

[0011] According to one aspect of the embodiment, the water discharge control system can transition to the power-saving mode at an appropriate time by transitioning to the power-saving mode in response to acquisition of predetermined first operation information. Therefore, the water discharge control system can suppress an increase in power consumption. For example, the water discharge control system can transition to the power-saving mode appropriately when the user finishes use, triggered by a user operation such as a gesture, thereby suppressing unnecessary power consumption.

[0012] In one aspect of the embodiment, the water discharge control system transitions to the power saving mode when, in the water discharge control mode, the change in size and position of the detected object remains less than a predetermined amount for a predetermined period of time or more.

[0013] According to one aspect of the embodiment, the water discharge control system can transition to the power-saving mode at an appropriate timing by transitioning to the power-saving mode when the change in the size and position of the detected object continues to be less than a predetermined amount for a predetermined period of time or more. Therefore, the water discharge control system can suppress an increase in power consumption. For example, if the size and position of the object are stationary, such as when an object is placed on the device, the water discharge control system can determine that the user does not intend to discharge water and transition to the power-saving mode.

[0014] In one aspect of the embodiment, the water discharge control system transitions to a second power saving mode that consumes even less power than the power saving mode when a predetermined time has passed since transitioning from the water discharge control mode to the power saving mode.

[0015] According to one aspect of the embodiment, the water discharge control system can further reduce power consumption by switching to a second power saving mode, which consumes even less power than the power saving mode, after a predetermined time has elapsed since switching to the power saving mode. Therefore, the water discharge control system can suppress an increase in power consumption.

[0016] In one aspect of the embodiment, the water discharge control system transitions to a second power saving mode that consumes even less power than the power saving mode when the control unit acquires specified second operation information in the water discharge control mode.

[0017] According to one aspect of the embodiment, the water discharge control system can further reduce power consumption by switching to a second power-saving mode, which consumes even less power than the power-saving mode, in response to the acquisition of certain second operation information. Therefore, the water discharge control system can suppress an increase in power consumption. For example, the water discharge control system can switch to the power-saving mode appropriately when the user finishes using the device, triggered by a user operation such as a gesture, thereby suppressing unnecessary power consumption.

[0018] In one aspect of the embodiment, the water discharge control system transitions from the power saving mode to the water discharge control mode based on a change in the detection result by the detection unit.

[0019] According to one aspect of the embodiment of the water discharge control system, the transition from power saving mode to water discharge control mode is triggered by the sensor detection result, so that the transition to water discharge control mode can be made naturally without requiring user operation.

[0020] In one aspect of the embodiment, the water discharge control system transitions to the water discharge control mode when, in the power saving mode, the control unit detects a change in the state of the detected object or acquires information about a new detected object.

[0021] According to one aspect of the embodiment of the water discharge control system, the transition from power saving mode to water discharge control mode is triggered by the sensor detection result, so that the transition to water discharge control mode can be made naturally without requiring user operation.

[0022] In one aspect of the embodiment, the water discharge control system transitions to the water discharge control mode when, in the power saving mode or the second power saving mode, the control unit acquires a change in the detection information by the detection unit that is greater than or equal to a predetermined value.

[0023] According to one aspect of the embodiment of the water discharge control system, the transition from the power saving mode or the second power saving mode to the water discharge control mode is triggered by the sensor detection result, so that the transition to the water discharge control mode can be made naturally without requiring any operation by the user.

[0024] In one aspect of the embodiment, the water discharge control system transitions to the power saving mode in the water discharge control mode when the absence of the detectable object continues for a predetermined period of time or more, or when the change in size and position of the detectable object is less than a predetermined amount of change for a predetermined period of time or more, and transitions from the power saving mode to the water discharge control mode when the detection unit detects the detectable object in the power saving mode.

[0025] According to the water discharge control system of one aspect of the embodiment, the transition from the water discharge control mode to the power saving mode is triggered by time, and the transition from the power saving mode to the water discharge control mode is triggered by detection by the detection unit, thereby saving power without requiring conscious operation by the user and enabling a natural transition to the water discharge control mode when necessary. Therefore, the water discharge control system can suppress an increase in power consumption.

[0026] A water discharge control system according to one aspect of the embodiment transitions to the power saving mode in the water discharge control mode when the absence of the detected object continues for a predetermined period of time or more, or when the change in size and position of the detected object is less than a predetermined amount of change for a predetermined period of time or more, and transitions to a second power saving mode that consumes even less power than the power saving mode if a predetermined period of time or more has passed since transitioning from the water discharge control mode to the power saving mode in the power saving mode.

[0027] According to one aspect of the embodiment, the water discharge control system switches between two power-saving modes using a time trigger, thereby enabling further power savings without requiring any conscious operation by the user. Therefore, the water discharge control system can suppress increases in power consumption.

[0028] The water discharge control system according to one aspect of the embodiment further includes a notification unit that notifies the user that the water discharge control mode or the power saving mode is being selected.

[0029] According to the water discharge control system of one aspect of the embodiment, by notifying the user of the mode, it is possible to easily check whether the mode has been changed or not.

[0030] In the water discharge control system according to one aspect of the embodiment, the detection unit is an imaging means that captures an image of at least the water discharge area.

[0031] According to the water discharge control system according to one aspect of the embodiment, more precise water discharge control is possible based on the image captured by the imaging means.

[0032] In one aspect of the embodiment, the control unit acquires characteristic information of the detected object, including at least one of the size, type, distance from the water outlet, and position of the detected object.

[0033] According to one aspect of the embodiment, the water discharge control system makes it possible to control the water discharge in accordance with the user's intentions by basing it on any of the important factors that determine the water discharge state, such as the size, type, distance from the water outlet, and position of the detected object.

[0034] In the water discharge control system according to one aspect of the embodiment, in the water discharge control mode and the power saving mode, the control unit causes the water discharge unit to discharge water based on the detection result of the detection unit.

[0035] According to one aspect of the embodiment, in the water discharge control system, water discharge from the water discharge section is performed based on the detection results of the detection section in the water discharge control mode and the power saving mode, making it possible to discharge water even in the power saving mode.

[0036] In the water discharge control system according to one aspect of the embodiment, the water discharge start condition based on the detection result of the detection unit is different between the water discharge control mode and the power saving mode.

[0037] For example, the water discharge control mode and the power saving mode have different power consumptions, and therefore the control response speeds may differ. Therefore, according to one aspect of the embodiment, by changing the water discharge conditions, water can be discharged at approximately the same speed even in the different modes, and water can be discharged even in the power saving mode.

[0038] In the water discharge control system according to one aspect of the embodiment, in the water discharge control mode, the control unit controls the water discharge state using a learning model that has learned the characteristics of the detected object.

[0039] According to a water discharge control system according to one aspect of the embodiment, more precise control is possible by using a learning model (also called a model, AI, etc.) learned through machine learning.

[0040] In the water discharge control system according to one aspect of the embodiment, the time interval for detecting the presence or absence of the object in the power saving mode is longer than the time interval in the water discharge control mode.

[0041] According to one aspect of the embodiment, the water discharge control system can reduce power consumption while determining the water discharge conditions by making the time interval for detecting the presence or absence of an object in the power saving mode longer than the time interval in the water discharge control mode. Therefore, the water discharge control system can suppress an increase in power consumption. For example, the water discharge control system can reduce power consumption while determining the water discharge conditions by reducing the number of images taken per second in the power saving mode compared to the water discharge control mode.

[0042] A control system according to one aspect of the embodiment includes a control unit that performs at least one of determining the presence or absence of an object to be detected or extracting characteristic information about the object to be detected based on detection information from a detection unit that detects an object to be detected in a plumbing device, and controls the plumbing device based on the results of the determination or extraction, and is characterized by having a power saving mode that reduces power consumption in the control unit, and a control mode that increases power consumption in the control unit more than in the power saving mode and in which the control unit controls the plumbing device based on the detection results of the detection unit.

[0043] According to one aspect of the embodiment, a control system has a power-saving mode that reduces power consumption in the control unit and a control mode in which power consumption in the control unit is increased compared to the power-saving mode and the control unit controls the plumbing appliance based on the detection results of the detection unit, thereby enabling control using the power-saving mode. Therefore, the control system can suppress increases in power consumption. For example, the control system has a normal control mode and a power-saving mode that consumes less power than the normal control mode, and can suppress power consumption by increasing power consumption only when necessary and saving power otherwise.

[0046] Hereinafter, an embodiment of a control system disclosed in the present application will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiment described below.

[0047] <1. Embodiment> First, a water discharge control system 1, which is an example of a control system according to an embodiment, will be described below. To control water discharge and stopping (also referred to as "water discharge stopping"), the water discharge control system 1 detects an object (also referred to as "detected object") based on information detected by a detection unit such as an imaging means for capturing images, and controls water discharge stopping depending on whether the detected object (detected object) is an object for which water discharge control is to be performed (also referred to as "water discharge target object"). For example, the object may be kitchen-related objects such as ingredients, tableware, and cooking utensils (hereinafter also referred to as "supplies"), a part of a person's (also referred to as a "user's") body, head, hands, or other parts of the human body, or kitchen elements such as a stove, sink, and water discharge unit. Furthermore, the water discharge target object includes at least one of a person's (user's) hand and an item. Note that the processes described for the water discharge control system according to each embodiment, such as the water discharge control system 1, may be performed by any device capable of performing the processes, depending on the device configuration included in the water discharge control system.

[0048] <1-1. Water discharge control system configuration> The configuration of a water discharge control system 1 according to an embodiment will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a schematic perspective view of a water discharge control system according to an embodiment. Fig. 2 is a diagram showing an example of the configuration of a water discharge control system according to an embodiment.

[0049] As shown in Figures 1 and 2, the water discharge control system 1 has a kitchen main body 2, an imaging unit 10, a control unit 100, a water valve 101, a purified water valve 102, a hot water valve 103, and a flow rate adjustment valve 104. The kitchen main body 2 is a plumbing equipment main body. The kitchen main body 2 has a water discharge unit 30, a sink 40, and a stove unit 50 on an upper surface unit 20 where a user performs tasks such as cooking and washing dishes and other objects. For example, the kitchen main body 2 may be a system kitchen.

[0050] The water discharge control system 1 may also include a water supply 80 and a water heater 81. The water supply 80 and the water heater 81 are components for supplying water to be discharged from the water discharge unit 30 via a water valve 101, a purified water valve 102, a hot water valve 103, a flow rate adjustment valve 104, and the like. For example, the water supply 80 is a water supply tool connected to a water distribution pipe or the like, and is connected to the water valve 101, the purified water valve 102, and the water heater 81. The water heater 81 is a device for heating water supplied from the water supply 80 to hot water, and is connected to the hot water valve 103. For example, the hot water temperature of the water heater 81 may be controlled by the control unit 100. In this case, the water heater 81 supplies hot water to the water discharge unit 30 via the hot water valve 103 at a temperature according to the control of the control unit 100. Note that the configuration shown in FIG. 2 is merely an example, and any configuration may be adopted as long as it is possible to discharge water in a desired manner.

[0051] 1 and 2 is merely an example, and any configuration can be adopted for the kitchen body 2. For example, the kitchen body 2 does not have to include the stove unit 50. In this case, the stove unit 50 may be provided separately from the kitchen body 2.

[0052] 1, a wall cabinet 60 and a range hood 70 are provided above the kitchen body 2, that is, on the side facing the upper surface 20 of the kitchen body 2. The wall cabinet 60 and the range hood 70 do not necessarily have to be provided.

[0053] The upper surface 20 of the kitchen main body 2 is used for user work. For example, the surface of the upper surface 20 of the kitchen main body 2 between the sink 40 and the stove unit 50 functions as a work surface where the user can perform processing such as cutting ingredients or place dishes after washing. Furthermore, multiple work surfaces may be arranged, such as between the sink 40 and the stove unit 50 and on the right side of the sink 40.

[0054] Water discharger 30 has a water discharge port 321 provided in head 32, which is the tip end portion of water discharge pipe 31, and discharges (spouts) water from water discharge port 321. For example, water discharger 30 may be able to discharge water in any desired form (shower, straight, etc.) from water discharge port 321. In this case, water discharger 30 may be able to switch between straight and shower water discharge from water discharge port 321. For example, water discharger 30 may discharge water in a form selected by the user.

[0055] 1 and 2, the water discharge unit 30 can switch between discharging a plurality of types of water, such as raw water, purified water, and hot water (also referred to as "hot water" or "warm water"), in accordance with the control of the control unit 100 on the water valve 101, the purified water valve 102, and the hot water valve 103. The water discharge unit 30 can also change the discharge flow rate (also referred to simply as "flow rate"), such as the instantaneous discharge flow rate, of any type of water, such as raw water, purified water, or hot water (warm water), in accordance with the control of the flow rate adjustment valve 104 by the control unit 100. The water discharge unit 30 may be configured to discharge only raw water. In this case, the water discharge control system 1 has only the water valve 101 among the water valve 101, the purified water valve 102, and the hot water valve 103. The water discharge unit 30 refers to, for example, the part exposed from the kitchen main body 2.

[0056] Sink 40 is a recess recessed from the surface of upper surface 20, and functions as a water receiving portion that receives water from water discharger 30. Sink 40 is used, for example, for washing objects such as dishes, and is a tank-like stand equipped with a drainage groove that drains water from water discharger 30, etc.

[0057] The stove unit 50 is a stove equipment used by a user for heating operations for cooking. While FIGS. 1 and 2 show an example in which the stove unit 50 has two heating units, 51 and 52, the stove unit 50 may have one heating unit or three or more heating units. The heating units 51 and 52 perform heating using any heat source, such as gas or electricity. In this way, the heating units 51 and 52 can be configured as any type, such as an electric stove, an induction stove, or a gas stove.

[0058] The control unit 100 is a control device that controls the discharge of water. The control unit 100 controls the discharge of water by controlling the cold water valve 101, the purified water valve 102, the hot water valve 103, and the flow rate adjustment valve 104 based on detection information (also referred to as "sensor information") detected by each sensor such as the imaging unit 10. The control unit 100 detects an object to be discharged from an image captured by the imaging unit 10, and controls the water discharge unit 30 based on the detection result. Note that the processing using the image captured by the imaging unit 10 is one example, and the control unit 100 may control the discharge of water using sensor information detected by any sensor, not limited to the imaging unit 10.

[0059] For example, the control unit 100 controls the type of water discharge by controlling the switching of the cold water valve 101, the purified water valve 102, and the hot water valve 103 based on information detected by each sensor such as the imaging unit 10. For example, the control unit 100 controls the water discharge flow rate, such as the instantaneous water discharge flow rate, by controlling the flow rate adjustment valve 104 based on information detected by each sensor such as the imaging unit 10.

[0060] Furthermore, the control settings of the control unit 100 for the cold water valve 101, the purified water valve 102, the hot water valve 103, and the flow rate adjustment valve 104 may be changed by the user to their preferred settings. For example, the control settings may be changed by the user to reduce the flow rate of purified water discharged to food ingredients, or to change the water discharged to cold water for stains. When detecting an object to be discharged from an image, the control unit 100 performs any processing on the captured image, such as brightness and color correction (image correction), monochrome / color conversion (image conversion), object identification (image recognition), and area measurement (image feature extraction).

[0061] The water valve 101 is, for example, a solenoid valve, and functions as a valve for discharging raw water to the water discharge portion 30. The purified water valve 102 is, for example, a solenoid valve, and functions as a valve for discharging purified water to the water discharge portion 30. The hot water valve 103 is, for example, a solenoid valve, and functions as a valve for discharging hot water (warm water) to the water discharge portion 30. The control unit 100 is connected to each of the water valve 101, the purified water valve 102, and the hot water valve 103. Note that instead of the water valve 101, the purified water valve 102, and the hot water valve 103, a single flow path switching valve may be used to switch between each type of water discharge (raw water, purified water, hot water, etc.).

[0062] For example, the control unit 100 is connected to a water valve 101 that switches between discharging and stopping the raw water by the water discharge unit 30. The control unit 100 controls the discharge and stopping of raw water by the water discharge unit 30 using a control signal that opens and closes the water valve 101.

[0063] For example, the control unit 100 is connected to a purified water valve 102 that switches between discharging and stopping purified water by the water discharge unit 30. The control unit 100 controls the discharging and stopping of purified water by the water discharge unit 30 using a control signal that opens and closes the purified water valve 102.

[0064] For example, the control unit 100 is connected to a hot water valve 103 that switches between discharging and stopping hot water from the water discharge unit 30. The control unit 100 controls the discharging and stopping of hot water from the water discharge unit 30 by a control signal that opens and closes the hot water valve 103.

[0065] Flow rate adjustment valve 104 is, for example, a control valve that can continuously change the valve opening, and functions as a valve for adjusting the flow rate of water discharged from water discharger 30. For example, flow rate adjustment valve 104 supplies the type of water selected by controlling cold water valve 101, purified water valve 102, and hot water valve 103 to water discharger 30 at a valve opening controlled by control unit 100. Note that any valve configuration may be used for flow rate adjustment valve 104 as long as it can be adjusted to any valve opening (position), such as 0 to 100%.

[0066] For example, the control unit 100 is connected to a flow rate adjustment valve 104 that adjusts the water discharge flow rate, such as the instantaneous water discharge flow rate, of the water discharge unit 30. The control unit 100 controls the water discharge flow rate, such as the instantaneous water discharge flow rate, of the water discharge unit 30 using a control signal that adjusts (specifies) the valve opening degree of the flow rate adjustment valve 104.

[0067] Furthermore, the control unit 100 is communicably connected to each sensor, such as the imaging unit 10, via a predetermined network, such as the Internet, either wired or wirelessly. For example, the control unit 100 has a communication function (communication unit) for transmitting and receiving information to and from other devices. The communication function (communication unit) of the control unit 100 is realized by a communication device, a communication circuit, or the like. The control unit 100 is connected to an arbitrary network via wired or wirelessly using the communication function, and transmits and receives information to and from an external information processing device. For example, the control unit 100 transmits and receives information to and from the imaging unit 10, etc. Note that the control unit 100 may be connected to each sensor in any manner as long as it is possible to transmit and receive information, and may be communicably connected via wired or wireless.

[0068] The control unit 100 may be disposed in any location. The control unit 100 may be provided inside the space corresponding to the kitchen main body 2 (kitchen room), or may be provided outside the space corresponding to the kitchen main body 2 (kitchen room).

[0069] The control unit 100 may be configured and arranged in any manner as long as it can control the switching of the cold water valve 101, the purified water valve 102, and the hot water valve 103, adjust the valve opening of the flow rate adjustment valve 104, and communicate with and process sensors such as the imaging unit 10. The control unit 100 may also be arranged inside the kitchen main body 2. The control unit 100 may also be arranged outside the kitchen main body 2, rather than inside it. Details of the control unit 100 will be described later.

[0070] The imaging unit 10 is a detection unit that detects at least the water discharge area. For example, the imaging unit 10 is an imaging means that captures an image of a wet space or the like. Note that the imaging unit 10 is merely one example of a detection unit, and any configuration can be employed, such as a distance image sensor using an infrared sensor, as long as the detection target is the water discharge area and the sensor is capable of detecting information used by the control unit 100 to control the wet equipment.

[0071] The imaging unit 10 captures an image of at least the water discharge area. The imaging unit 10 functions as a sensor unit that acquires information used to control water discharge. For example, the imaging unit 10 is a camera module that acquires images by capturing an image of a predetermined area, such as the inside of the sink 40, or a sensor unit that uses an image sensor. The imaging unit 10 captures images of the bathroom space around the water discharge unit 30. For example, the imaging unit 10 captures images of the bathroom space including the sink 40, etc.

[0072] The imaging unit 10 is disposed in a position where it can capture an image of a desired range (area). For example, the imaging unit 10 is provided on the upper part (upper side) of the kitchen main body 2. The imaging unit 10 is provided in a position facing the kitchen main body 2 from above the kitchen main body 2. FIGS. 1 and 2 show, as an example, a case where the imaging unit 10 is disposed on the underside of a wall cabinet 60 provided above the kitchen main body 2. Note that the placement of the imaging unit 10 shown in FIGS. 1 and 2 is merely an example, and the imaging unit 10 may be disposed in any position as long as it can capture an image of a desired range.

[0073] The imaging unit 10 uses any sensor such as a CCD (Charge Coupled Device) sensor or a CMOS (Complementary Metal Oxide Semiconductor) sensor. For example, the imaging unit 10 is an area sensor or a distance measuring sensor that uses an image sensor. The imaging unit 10 captures an image of the water-related space around the water discharger 30.

[0074] Also, for example, the imaging unit 10 is disposed facing in a direction to capture an image of the sink 40. Note that the imaging unit 10 may be disposed in any manner as long as it can detect (capture) an object. Also, the imaging unit 10 may capture a still image or a moving image.

[0075] The imaging unit 10 is connected to the control unit 100 via a predetermined network so as to be able to communicate with each other via a wired or wireless connection. The imaging unit 10 transmits various types of information to the control unit 100. For example, the imaging unit 10 transmits information related to an acquired image to the control unit 100. For example, the imaging unit 10 may be connected to the control unit 100 so as to be able to communicate with each other via a predetermined wireless communication function such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). Note that the control unit 100 and the imaging unit 10 may be connected in any manner as long as they are able to send and receive information, and may be connected to each other via a wired or wireless connection so as to be able to communicate with each other. For example, the imaging unit 10 may be connected to the control unit 100 so as to be able to communicate with each other via a wired or wireless connection.

[0076] When describing various sensors such as the imaging unit 10 without distinction, they may be referred to as "sensors." When describing information acquired by various sensors such as the imaging unit 10 without distinction, they may be referred to as "sensor information." Sensor information is a concept that includes information acquired by various sensors for water discharge control, such as information acquired by the imaging unit 10.

[0077] 1 and 2 are merely examples, and the water discharge control system 1 can have any device configuration. For example, in FIG. 2, the solid line connections between each component indicate the communication (transmission and reception) and control relationships of signals (information) between the components, and the dotted line connections between each component indicate an example of the relationship of water flow, but the relationships are not limited to those shown in FIG. 2, and any relationship can be adopted. For example, in the water discharge control system 1, the control unit 100 may communicate with the water heater 81 and control the water heater 81. Also, for example, the water discharge control system 1 may not include a sensor. In this case, the control unit 100 of the water discharge control system 1 may communicate with a sensor not included in the water discharge control system 1 and control the water discharge using sensor information received (acquired) from the sensor. For example, the water discharge control system 1 may not include the imaging unit 10. In this case, the control unit 100 of the water discharge control system 1 may communicate with an imaging unit 10 that is not included in the water discharge control system 1, and use the image received (acquired) from the imaging unit 10 to control the water discharge.

[0078] Furthermore, the water discharge control system 1 may have a personal identification unit (identification device) that performs processing (personal identification) to identify the user who uses the kitchen main body 2. For example, the control unit 100 may function as the personal identification unit. For example, the personal identification unit of the water discharge control system 1 may perform personal identification based on an image of a person included in an image. Note that the above is merely an example, and the water discharge control system 1 may perform personal identification by any method as long as it is possible to identify the user who uses the kitchen main body 2. For example, the personal identification unit of the water discharge control system 1 may acquire information for identifying the user who uses the kitchen main body 2 by communicating with a device such as a smartphone owned by the user, or by the user's operation on a remote control, and then perform personal identification of the user.

[0079] Furthermore, the water discharge control system 1 may also include sensors other than the imaging unit 10. For example, the water discharge control system 1 may also include a human body detection sensor. The human body detection sensor has the function of detecting a human body. For example, the human body detection sensor is realized by a pyroelectric sensor using an infrared signal. For example, the human body detection sensor may be realized by a μ (microwave) wave sensor. Note that the above is just an example, and the human body detection sensor is not limited to the above, and may detect a human body by various means. For example, the human body detection sensor detects a person (such as a user) who enters the space (kitchen room) in which the kitchen main body 2 is provided. The human body detection sensor transmits a detection signal to the control unit 100.

[0080] The water discharge control system 1 also has a notification unit that issues a notification. The notification unit may be provided in the kitchen main body 2, or may be provided in a location other than the kitchen main body 2. The notification unit may be located in any desired location as long as it can provide the desired notification; for example, the control unit 100 may have a notification unit. The notification unit notifies the user of the mode. For example, the notification unit notifies the user that the mode is the water discharge control mode or the power saving mode.

[0081] For example, if the notification unit notifies by display, it may have a display device (such as a display) that displays the mode. In this case, the notification unit notifies that the water discharge control mode or the power saving mode is in effect by displaying information indicating that the mode is in the water discharge control mode or the power saving mode on the display device. Furthermore, for example, if the notification unit notifies by audio output, it may have an audio output device (such as a speaker) that outputs the mode by audio. In this case, the notification unit notifies that the mode is in the water discharge control mode or the power saving mode by outputting information indicating that the mode is in the water discharge control mode or the power saving mode by audio output from the audio output device.

[0082] For example, the notification unit may be communicably connected to the control unit 100 via a predetermined wireless communication function such as Bluetooth or Wi-Fi. Note that the control unit 100 and the notification unit may be connected in any manner as long as they are capable of transmitting and receiving information, and may be connected to each other via a wired or wireless connection. For example, the notification unit may be connected to the control unit 100 via a wired or wireless connection. The notification unit notifies the user of information received from the control unit 100. For example, when the notification unit receives information from the control unit 100 indicating that the mode is the water discharge control mode or the power saving mode, the notification unit notifies the user of information indicating that the mode is the water discharge control mode or the power saving mode.

[0083] <1-2. Configuration of the control unit (control device)> Next, each component of the control unit 100 will be described in detail. The control unit 100 may be, for example, an information processing device (computer) used to control various components and processes. The control unit 100 may have, for example, a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), and may be realized by executing a program stored inside the control unit 100 (for example, an information processing program according to the present disclosure) using RAM or the like as a working area. The control unit 100 may be, for example, a microcomputer equipped with any processor such as a CPU. The control unit 100 may also have, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0084] The control unit 100 performs at least one of determining whether or not an object is present or extracting characteristic information about the object based on the detection information from the imaging unit 10 that detects the object in the plumbing equipment, and controls the plumbing equipment based on the results of the determination or extraction. The control unit 100 performs at least one of determining whether or not an object is present or extracting characteristic information about the object based on the detection results from the imaging unit 10, and controls the water discharge state from the water discharger 30 based on the results of the determination or extraction.

[0085] The control unit 100 controls the plumbing equipment according to the mode. The control unit 100 controls the water discharge and stopping according to the mode. For example, the control unit 100 controls the water discharge and stopping according to a mode selected from a water discharge control mode (also called a "control mode"), a power saving mode that is more power-efficient than the control mode, and a second power saving mode that is more power-efficient than the power saving mode. Note that the control mode may also be referred to as a normal power mode, a normal mode, etc., in terms of the difference in power consumption between the control mode and a power-saving mode such as the power saving mode and the second power saving mode.

[0086] For example, the water discharge control mode (control mode) is a normal power mode (normal mode) in which the plumbing equipment is controlled based on the detection results of the imaging unit 10. Also, for example, the power saving mode is a mode in which power consumption is lower than that of the water discharge control mode (control mode). For example, the power saving mode is a mode in which power consumption is lowered by lowering the processing load of the control of the plumbing equipment by the control unit 100 compared to the water discharge control mode (control mode). For example, the control unit 100 has a power saving mode in which power consumption is reduced, and a water discharge control mode in which power consumption is increased more than that of the power saving mode and water is discharged from the water discharger 30 based on the detection results of the imaging unit 10.

[0087] As shown in FIG. 2, control unit 100 has a switching adjustment unit 110, a processing unit 120, a storage unit 130, and an acquisition unit 140, and realizes or executes the information processing functions and actions described below. Note that the internal configuration of control unit 100 is not limited to the configuration shown in FIG. 2 and may be other configurations that perform the information processing described below. For example, processing unit 120 may be divided into a determination unit that performs processing related to determination, an operation detection unit that detects user operations, and a water discharge / stop control unit that performs processing related to controlling the water discharge / stop of water discharge unit 30. Furthermore, the processing performed by control unit 100 may be executed by a cloud server (also referred to as the cloud). In this case, the cloud and control unit 100 are connected via a predetermined network, either wired or wirelessly.

[0088] The switching adjustment unit 110 changes the water discharge mode, such as stopping or discharging water, of the water discharge unit 30. The water discharge mode refers to one mode of water discharge, such as the type of water discharge (raw water, purified water, hot water, etc.), the water discharge form (shower, straight, etc.), and the water discharge flow rate (instantaneous water discharge flow rate, etc.). The above is merely an example, and the water discharge mode may be classified in any way. For example, if purified water can be discharged as hot water, the type of water discharge may be classified as raw water, purified water at room temperature, hot water, purified water at high temperature, etc.

[0089] The switching adjustment unit 110 switches the opening and closing of the water valve 101, the purified water valve 102, and the hot water valve 103 in response to instructions from the processing unit 120. The switching adjustment unit 110 sends control signals to the water valve 101, the purified water valve 102, and the hot water valve 103, and switches the opening and closing of the water valve 101, the purified water valve 102, and the hot water valve 103, thereby switching the type of water discharged from the water discharge unit 30.

[0090] Switching adjustment unit 110 adjusts the valve opening of flow rate adjustment valve 104 in response to instructions from processing unit 120. Switching adjustment unit 110 sends a control signal to flow rate adjustment valve 104 and adjusts (sets) the valve opening of flow rate adjustment valve 104, thereby adjusting the water discharge flow rate, such as the instantaneous water discharge flow rate, of water discharge unit 30.

[0091] The processing unit 120 executes various processes related to the water discharge control. The processing unit 120 functions as a determination unit that performs various determinations. For example, the processing unit 120 determines the state of a detected object (imaged object) detected from an image captured by the imaging unit 10. The processing unit 120 functions as an operation detection unit that detects a user's operation. The processing unit 120 functions as a calculation unit that executes arithmetic (calculation) processing related to control. The processing unit 120 may be a microcomputer or the like equipped with a processor such as a CPU that is separate from the other components of the control unit 100.

[0092] The processing unit 120 performs control according to the mode. The processing unit 120 performs control according to a mode selected from a plurality of modes. For example, the processing unit 120 controls water discharge and stopping according to a mode selected from the control mode (water discharge control mode), the power saving mode, and the second power saving mode. The processing unit 120 executes a learning model execution program 133 that executes the learning model 134, and performs processing using the learning model 134. The processing unit 120 performs control related to water discharge and stopping using a water discharge control program 135.

[0093] The processing unit 120 switches modes related to the control of the plumbing equipment based on information such as detection by sensors such as the imaging unit 10 and user operation. For example, the processing unit 120 switches modes related to the control of water discharge and stop based on information such as detection by sensors such as the imaging unit 10 and user operation. For example, the processing unit 120 determines whether to switch modes using information such as mode switching conditions stored in the memory unit 130. The processing unit 120 switches modes depending on the determination result using information such as mode switching conditions stored in the memory unit 130.

[0094] If the processing unit 120 determines that the mode switching conditions to the water discharge control mode are met, it switches the mode to the water discharge control mode. Note that if the processing unit 120 determines that the mode switching conditions to the water discharge control mode are met in the water discharge control mode, it maintains the mode in the water discharge control mode. If the processing unit 120 determines that the mode switching conditions to the power saving mode are met, it switches the mode to the power saving mode. If the processing unit 120 determines that the mode switching conditions to the power saving mode are met in the power saving mode, it maintains the mode in the power saving mode.

[0095] The processing unit 120 functions as a detection unit that detects the object of water discharge using sensor information. The processing unit 120 detects the object of water discharge contained in the image captured by the imaging unit 10. The processing unit 120 determines whether or not the object has been detected. When detecting the object of water discharge contained in the image, the processing unit 120 performs any processing on the captured image, such as brightness and color correction (image correction), monochrome / color conversion (image conversion), object identification (image recognition), and area measurement (image feature extraction).

[0096] The processing unit 120 detects objects included in the image and their positions (coordinates, etc.) through image processing. The processing unit 120 may detect the objects included in the image and their positions (ranges) through any processing as long as it is possible to acquire information indicating the objects included in the image and their positions. This point will be described in detail later.

[0097] The processing unit 120 calculates (estimates) the moving speed of the object based on the image captured by the imaging unit 10. For example, the processing unit 120 estimates the moving speed of the object based on a change in the position (coordinates, etc.) of the object in a video. For example, the processing unit 120 estimates the moving speed of the object based on, for example, the frame rate of the video (i.e., time information) and a change in the position of the object in the video (i.e., information on the moving distance). For example, the processing unit 120 estimates the moving speed of the object by, for example, dividing the moving distance of the object in the video by the time corresponding to the frame rate of the video. Note that the above-described processing is merely an example, and the processing unit 120 may estimate the moving speed of the object using various information as appropriate.

[0098] The processing unit 120 may use the sensor information to determine whether to discharge water, and if so, select the type of water to be discharged—raw water, purified water, or hot water—based on the content stored in the memory unit 130. In this case, the processing unit 120 determines to open the valve corresponding to the selected type of water from among the cold water valve 101, the purified water valve 102, and the hot water valve 103. The processing unit 120 generates a control signal instructing the determined valve to be opened. Using the generated control signal, the processing unit 120 instructs the switching adjustment unit 110 to switch the cold water valve 101, the purified water valve 102, and the hot water valve 103 between open and closed states.

[0099] Furthermore, when discharging water, the processing unit 120 may determine the instantaneous water discharge flow rate based on the contents stored in the memory unit 130. In this case, the processing unit 120 determines the valve opening degree of the flow rate adjustment valve 104 based on the determined instantaneous water discharge flow rate. The processing unit 120 generates a control signal instructing opening at the determined valve opening degree. The processing unit 120 uses the generated control signal to instruct the switching adjustment unit 110 to adjust (set) the valve opening degree of the flow rate adjustment valve 104.

[0100] The processing unit 120 determines the object to be discharged water from the image captured by the imaging unit 10. The processing unit 120 can determine the user's hand and the implement from the image captured by the imaging unit 10.

[0101] The processing unit 120 functions as a water discharge control unit that controls the water discharge state from the water discharge unit 30. For example, the water discharge state includes five elements: water discharge stop, flow rate, temperature, type, and water discharge form (also simply referred to as "form"). Note that the above water discharge state elements are merely examples, and the water discharge state elements may be any elements. For example, the water discharge state may include six or more elements, or may include four or fewer elements. For example, if the type is an element that also includes the temperature aspect, such as cold water, hot water, or purified water, the water discharge state may include four elements: water discharge stop, flow rate, type, and form, without including the element of temperature.

[0102] Processing unit 120 controls switching adjustment unit 110. Processing unit 120 controls the stopping and spouting of water from water discharger 30 by controlling the switching of switching adjustment unit 110. Processing unit 120 controls the stopping and spouting of water from water discharger 30 by controlling switching adjustment unit 110 based on the determination result.

[0103] Processing unit 120 determines the size of the object to be discharged. Processing unit 120 controls the water discharge state from water discharge unit 30 based on at least one of the size of the object to be discharged determined by the determination unit, the type of object to be discharged, or the distance between water discharge outlet 321 of water discharge unit 30 and the object to be discharged. Processing unit 120 increases the water discharge state as the object to be discharged is larger.

[0104] The processing unit 120 classifies the object to be discharged as either a tool or a human hand, and controls the state of discharge of water based on the classification result. If the object to be discharged as a tool, the processing unit 120 further classifies the object to be discharged as either an article or a food ingredient, and controls the state of discharge of water based on the classification result.

[0105] The processing unit 120 determines the distance between the water discharge port 321 and the object to be discharged based on the image, and controls the water discharge state according to changes in the distance. The processing unit 120 determines that an object having a predetermined moving speed is an object to be discharged. The processing unit 120 determines that an object having a moving speed that meets a predetermined standard is an object to be discharged.

[0106] For example, the processing unit 120 determines that a detected object whose estimated moving speed is within a predetermined range is a target object for water discharge. For example, if the moving speed of the detected object is less than a first threshold value and greater than or equal to a second threshold value, the processing unit 120 determines that the detected object is a target object for water discharge. For example, the second threshold value is a predetermined value greater than the first threshold value. For example, if the moving speed of the detected object is within the range between the first threshold value and the second threshold value, the processing unit 120 estimates that the detected object is an object about which the user wants water discharged, and determines that the detected object is a target object for water discharge.

[0107] For example, the processing unit 120 determines that a detected object whose moving speed is less than the first threshold is not a target object for water discharge. For example, the processing unit 120 estimates that a detected object whose moving speed is less than the first threshold is an object placed there, and determines that it is not a target object for water discharge.

[0108] For example, the processing unit 120 determines that a detected object whose moving speed is equal to or greater than the second threshold is not a target for water discharge. For example, the processing unit 120 estimates that a detected object whose moving speed is equal to or greater than the second threshold is an object moving through the imaging area, and determines that the detected object is not a target for water discharge.

[0109] The processing unit 120 determines that, of the detected objects, those within the first region are objects to be subjected to water discharge. For example, the processing unit 120 determines that, of the detected objects, those within the first region, which is a predetermined range including the water discharge region WA1, are objects to be subjected to water discharge. The first region can be set to any range as long as it is possible to determine objects to be subjected to water discharge. For example, the first region may be a region including a position (water discharge drop position) where water discharged (spouted) from the water discharge port 321 falls, such as a position directly below the water discharge port 321. For example, the processing unit 120 detects objects in the first region and controls water discharge.

[0110] When the shape of the object to be discharged is a predetermined type, the processing unit 120 controls the water discharge state based on the predetermined type. When the size of the object to be discharged is changed while the object is held within the water discharge area, the processing unit 120 does not change the water discharge state.

[0111] Processing unit 120 controls the water discharge state according to the water discharge form acquired by acquisition unit 140. Processing unit 120 increases the instantaneous water discharge flow rate the larger the size of the object to be discharged, and changes the control of the instantaneous water discharge flow rate depending on the type of object to be discharged. Processing unit 120 increases the instantaneous water discharge flow rate the larger the size of the object to be discharged, and reduces the amount of change in the instantaneous water discharge flow rate when the object to be discharged is a human hand compared to when the object is an item.

[0112] The larger the size of the object onto which water is to be discharged, the smaller the amount of change in the instantaneous water discharge flow rate based on a change in the size of the object onto which water is to be discharged. When the water discharge mode is shower water discharge, the processing unit 120 reduces the amount of change in the instantaneous water discharge flow rate based on a change in the size of the object onto which water is to be discharged.

[0113] Processing unit 120 may function as a discharged water temperature adjustment unit that adjusts the temperature of water discharged from water discharge unit 30. For example, processing unit 120 controls water heater 81 to adjust the temperature of hot water supplied from water heater 81 to water discharge unit 30 via hot water valve 103. Processing unit 120 detects the degree of dirtiness of the object onto which water is to be discharged and increases the temperature of the discharged water.

[0114] The processing unit 120 detects user operations using sensor information. The processing unit 120 detects user operations related to controlling the water discharge state. For example, the processing unit 120 detects operations related to changing modes. For example, the processing unit 120 detects a mode switching operation by the user. For example, the processing unit 120 detects user operations based on user gestures detected from an image captured by the imaging unit 10. For example, the processing unit 120 detects user operations based on the user's hand movements (hand signs, etc.) detected from an image captured by the imaging unit 10.

[0115] Note that the above is merely an example, and the processing unit 120 may detect the user's operation using various information. For example, if an operation device such as an operation panel is provided in the kitchen main body 2, the processing unit 120 may detect the user's operation using operation information indicating the user's operation on the operation device.

[0116] The storage unit 130 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk. For example, the storage unit 130 is a computer-readable recording medium that non-temporarily records data used by an information processing program. The storage unit 130 stores various information such as information detected by various sensors. The storage unit 130 stores various information used to control water discharge.

[0117] The storage unit 130 stores various information used to detect an object onto which water is to be discharged. For example, the storage unit 130 stores various programs for detecting an object onto which water is to be discharged, determining whether or not water is to be discharged, and the like. For example, the storage unit 130 stores threshold values ​​used in the determination process related to the control of water discharge and stoppage. For example, the storage unit 130 stores threshold values ​​used in the determination process of whether or not an object onto which water is to be discharged has been detected.

[0118] In FIG. 2, the storage unit 130 stores a first image acquisition program 131, a second image acquisition program 132, a learning model execution program 133, a learning model 134, a water discharge control program 135, and the like.

[0119] Image acquisition programs such as the first image acquisition program 131 and the second image acquisition program 132 are programs that execute processing related to image acquisition. The image acquisition programs such as the first image acquisition program 131 and the second image acquisition program 132 are programs that determine the time interval for acquiring an image, the size of the image, and color information, and acquire the image from the imaging unit 10. For example, the second image acquisition program 132 is an image acquisition program that has a smaller processing load than the first image acquisition program 131, i.e., is more power-efficient.

[0120] For example, the second image acquisition program 132 may be an image acquisition program in which the time interval for acquiring images is longer than that of the first image acquisition program 131. Furthermore, for example, the second image acquisition program 132 may be an image acquisition program that reduces the image size compared to the first image acquisition program 131. Furthermore, for example, the second image acquisition program 132 may be an image acquisition program that reduces the color information of the image compared to the first image acquisition program 131.

[0121] The learning model execution program 133 is a program for executing models such as the learning model 134. The learning model execution program 133 executes models such as the learning model 134 at predetermined time intervals. For example, the learning model execution program 133 executes models such as the learning model 134 at different time intervals set for each of the power saving mode and the control mode. In this case, in the power saving mode, the learning model execution program 133 executes models such as the learning model 134 at the power saving time interval set for the power saving mode. Also, for example, in the control mode (normal mode), the learning model execution program 133 executes models such as the learning model 134 at the normal time interval set for the control mode (normal mode). The power saving time interval is set to be longer than the normal time interval.

[0122] The learning model 134 is a model (AI) that has been trained (generated) using machine learning technology. The learning model 134 executes processing using sensor information detected by a sensor. For example, the learning model 134 is a model that learns the characteristics of a detection target, such as a water-discharge target, and detects the detection target (object) from an image acquired by the imaging unit 10. For example, the learning model 134 is an object detection program. For example, the learning model 134 includes an image recognition model, which will be described later. The learning model 134 may also include a distance estimation model, which will be described later.

[0123] Although FIG. 2 illustrates only one learning model 134, multiple learning models 134 may be stored. For example, the storage unit 130 may store multiple learning models 134, each with a different processing load (calculation amount, etc.). In this case, the control unit 100 may switch between the power saving mode and the control mode by switching the learning model 134. For example, the control unit 100 may execute processing in the power saving mode using a power saving model, which is a learning model 134 with a small processing load, among the multiple learning models 134, and execute processing in the control mode using a normal model, which is a learning model 134 used in normal times and with a larger processing load than the power saving model.

[0124] The water discharge control program 135 is a program that executes control of water discharge and stopping. For example, the water discharge control program 135 executes control of water discharge and stopping based on the processing results (detection results, etc.) of the learning model 134 executed by the learning model execution program 133. For example, the water discharge control program 135 is a program that controls the time interval for water discharge control based on the detection results and controls water discharge.

[0125] The above is merely an example, and the memory unit 130 stores various information related to processing. The memory unit 130 stores various information related to mode switching by the processing unit 120 and control of water discharge and stop according to the mode. The memory unit 130 stores information related to the mode, including the mode set by the processing unit 120. For example, the memory unit 130 stores information (mode switching conditions, etc.) used by the processing unit 120 to determine whether or not to switch modes. For example, the memory unit 130 stores information (mode switching conditions, etc.) used by the processing unit 120 to determine whether or not to switch modes for each of the control mode (water discharge control mode), the power saving mode, and the second power saving mode.

[0126] The storage unit 130 may store various types of information depending on the purpose, without being limited to the above. The storage unit 130 may store sensor information detected by various sensors. The storage unit 130 may store the sensor information in association with the date and time when it was acquired. The storage unit 130 may store an image as sensor information. The storage unit 130 stores information indicating the processing result corresponding to the image in association with the image. The storage unit 130 stores the determination result determined for the image (presence or absence of an object to be discharged water, etc.) in association with the image.

[0127] The acquisition unit 140 acquires information. The acquisition unit 140 acquires various information from the storage unit 130. The acquisition unit 140 acquires various information from the kitchen main body 2. The acquisition unit 140 acquires various information collected in a space (kitchen room) corresponding to the kitchen main body 2 from the kitchen main body 2. The acquisition unit 140 acquires user identification information that identifies a user from the kitchen main body 2.

[0128] The acquisition unit 140 acquires sensor information detected by the sensor from the sensor. The acquisition unit 140 acquires sensor information of the user sensed by the sensor. The acquisition unit 140 receives information related to the image acquired by the imaging unit 10 from the imaging unit 10. The acquisition unit 140 may store the received various information in the storage unit 130.

[0129] The acquisition unit 140 acquires the water discharge mode from the water discharger 30. The acquisition unit 140 acquires information indicating whether the water discharge mode of the water discharger 30 is straight or shower. The acquisition unit 140 acquires information indicating the water discharge mode of the water discharger 30 from the water discharger 30. The acquisition unit 140 receives a signal (information) indicating the water discharge mode from the water discharger 30.

[0130] The above-described configuration of the control unit 100 is merely an example, and the control unit 100 may have various configurations other than the above. For example, if the control unit 100 has a function of displaying information, it may have a display unit.

[0131] <1-3. Area example> The water discharge area can be set arbitrarily, but an example of the water discharge area will be described using Fig. 3. Fig. 3 is a diagram showing an example of the area. Fig. 3 shows a case corresponding to a plan view (hereinafter simply referred to as "plan view") of the upper surface portion 20 from above the kitchen main body 2. For example, Fig. 3 shows an example of the water discharge area WA1.

[0132] In Fig. 3, the water discharge area WA1 includes an area that overlaps with the water discharge outlet (e.g., water discharge outlet 321) that discharges water from the water discharger 30 in a plan view. Note that the water discharge area WA1 shown in Fig. 3 is only an example, and the water discharge area can be changed to any range. For example, the water discharge area WA1 can be set to any range as long as it includes an area that overlaps with the water discharge outlet in a plan view.

[0133] <1-4. Example of processing using images> Here, an example of processing using an image executed by the water discharge control system will be described with reference to Fig. 4. Fig. 4 is a diagram showing an example of processing using an image executed by the water discharge control system. The processing using an image shown below may be executed by a model such as learning model 134, or may be executed by a program other than a model (for example, an image processing program, etc.).

[0134] Image IM1 in FIG. 4 shows an example of a case where an image captured by the imaging unit 10 is the processing target. In FIG. 4, the water discharge control system 1 shows an example of a processing result when the processing target is image IM1 that includes a human hand and utensils (tableware) as the detected object. For example, the water discharge control system 1 uses any image recognition technology to detect the area in image IM1 where the detected object is located. In FIG. 4, the water discharge control system 1 detects three areas where the detected object is located: area SG1 indicated by dotted lines, area SG2 indicated by dashed lines, and area SG3.

[0135] 4 shows an example in which a rectangular area is detected as the area where the detected object is located, but the area where the detected object is located is not limited to a rectangular area, and for example, the area where the detected object is located may be detected in more detail. For example, the area where the detected object is located may be detected in pixel units, or may be detected as a shape that follows the outer shape (outline) of the detected object.

[0136] For example, the water discharge control system 1 detects the size of the detected object as one of the indices used for water discharge control. For example, when the detected object is an object to be discharged, the water discharge control system 1 detects the size of the object to be discharged. For example, the water discharge control system 1 may detect the size of a rectangular area such as areas SG1 to SG3. For example, the water discharge control system 1 may detect the size of the object to be discharged based on the number of pixels included in area SG1 in which the dish that is the object to be discharged is located. Note that when the water discharge control system 1 detects a shape that follows the outline (contour) of the object to be discharged, it may detect the size of the object to be discharged based on the number of pixels included within that outline. In this way, the water discharge control system 1 may control using the size of the object itself, or may control using the size of the detection result of the object (rectangular area, etc.).

[0137] Furthermore, the water discharge control system 1 classifies (determines) the type of each detected object in the image IM1 using any image recognition technology. In FIG. 4, the water discharge control system 1 classifies the type of the detected object located in area SG1 of the image IM1 as a utensil. Furthermore, the water discharge control system 1 classifies the type of the detected objects located in areas SG2 and SG3 of the image IM1 as a human hand. Note that various conventional technologies can be applied to recognize objects contained in an image, and for example, image recognition technology utilizing various machine learning techniques such as deep learning may be used as appropriate.

[0138] Furthermore, the classification of the area and type of the detected object in the image may be performed by a single process. For example, when an image is input, the water discharge control system 1 may perform a process of classifying the area and type of the detected object in the image using an image recognition model that outputs information indicating the area and type of each detected object in the input image. In this case, the water discharge control system 1 may input the image IM1 to the image recognition model, and estimate (determine) the size and type of each detected object in the image IM1 based on the information indicating the area and type classification of the detected object in the image IM1 output by the image recognition model.

[0139] In this way, the water discharge control system 1 uses any image recognition technology to detect objects included in the image IM1 and classify (determine) the type of the detected objects. For example, the water discharge control system 1 uses any image recognition technology to determine to which of multiple types each of the objects detected in the image IM1 belongs.

[0140] For example, the water discharge control system 1 classifies (determines) the type of the detected object as one of the indices used for water discharge control. For example, the water discharge control system 1 may classify the detected object into one of a plurality of types based on individual names such as chopsticks, pot, plate, etc. For example, the water discharge control system 1 may classify the detected object into one of a plurality of types based on general classifications such as tableware, hands, food ingredients, etc. Furthermore, the water discharge control system 1 may classify the detected object into one of a plurality of newly defined types such as water-splashing dishes, water-collecting dishes, etc.

[0141] It should be noted that any classification can be adopted for the multiple types into which the detected object is classified. For example, the multiple types may be types based on a category classification. For example, the multiple types may be types based on a category classification used in general object recognition or the like. For example, the multiple types may be three types: human hands, supplies, and others. Alternatively, for example, the multiple types may be four types: human hands, objects, food ingredients, and others. Alternatively, for example, the multiple types may be four types: human hands, objects, food ingredients, and others.

[0142] For example, the plurality of types may be types based on classification of uses, for example, the plurality of types may include types based on classification of what uses the article is used for.

[0143] For example, the multiple types may be types based on a classification of shapes. For example, the multiple types may include types based on a classification of the shape of the article. For example, the multiple types may include types based on a classification of whether the article has a shape that is prone to splashing water. For example, the multiple types may include types based on the degree of susceptibility of the shape of the article to splashing water.

[0144] For example, the multiple types may be types based on a classification of materials. For example, the multiple types may include types based on a classification of what material the article is made of. For example, the multiple types may include types based on a classification of whether the article is made of a material that is prone to splashing water. For example, the multiple types may include types based on the degree of susceptibility to splashing water of the material of the article.

[0145] The above-described classification of types is merely an example, and any type can be adopted as long as the desired processing can be realized. The multiple types may be types based on a combination of at least two of category classification, use classification, shape classification, and material classification. The types may also have a hierarchical relationship. In this case, for example, items and ingredients may belong to a lower level of supplies, tableware and cooking utensils may belong to a lower level of items, and vegetables and meat may belong to a lower level of ingredients. The above-described hierarchical relationship is merely an example, and any hierarchical relationship can be adopted, and may be three or more levels. For example, knives and bowls may belong to a lower level of cooking utensils.

[0146] For example, the water discharge control system 1 estimates (calculates) the distance between the water discharge port and the target object (object onto which water is discharged) as one of the indices used for water discharge control. For example, the water discharge control system 1 may calculate the distance using AI based on an image, or may estimate the distance based on the size of the user's hand.

[0147] For example, when an image is input, the water discharge control system 1 may estimate the distance between the water spout and the object (object to be discharged) using a distance estimation model that outputs information indicating the distance between the object to be discharged in the input image and a predetermined position (the position of the water spout). In this case, the water discharge control system 1 may input the image IM1 to the distance estimation model, and estimate (calculate) the distance between the dish that is the object to be discharged and the water spout 321 based on information indicating the estimated distance between the dish that is the object to be discharged in image IM1 and the water spout 321 output by the distance estimation model. Note that the above is merely an example, and the water discharge control system 1 may estimate the distance between the water spout 321 and the object (object to be discharged) using various information as appropriate. For example, the water discharge control system 1 may estimate the distance between the water spout 321 and the object (object to be discharged) based on the size of at least one of the areas SG2 and SG3 that include a person's hand.

[0148] <1-5. Example of water discharge control system processing> Based on the above-mentioned content, the processing executed by the water discharge control system 1 will now be described.

[0149] <1-5-1. Mode Examples> First, an example of a mode will be described using Fig. 5. Fig. 5 is a diagram showing an example of a mode. Mode information MD1 in Fig. 5 indicates a case where the water discharge control system 1 has a water discharge control mode and a power saving mode, and switches between the water discharge control mode and the power saving mode.

[0150] In the water discharge control mode, the control unit 100 transitions to the power saving mode in response to a state in which there is no detected object continuing for a predetermined time or more. For example, the control unit 100 transitions to the power saving mode when there is no detected object continuing for a predetermined time or more after water discharge from the water discharge unit 30 has finished.

[0151] Furthermore, the control unit 100 may switch modes in response to an operation by the user. This will be described with reference to Fig. 6. Fig. 6 is a diagram showing an example of a mode switching operation by the user.

[0152] 6 shows an example in which the user makes a gesture with his / her hand HD to instruct the transition to the power saving mode. In this case, the control unit 100 acquires information (first operation information) indicating the user's first operation to instruct the transition to the power saving mode, and transitions to the power saving mode based on the acquired first operation information. For example, the control unit 100 may acquire the first operation information by acquiring an image including the user's gesture from the imaging unit 10 and analyzing the acquired image.

[0153] For example, the control unit 100 may transition to the power saving mode in response to acquiring predetermined first operation information in the water discharge control mode. For example, the control unit 100 may transition to the power saving mode when a first operation is performed by the user in the water discharge control mode.

[0154] Note that, although FIG. 6 has been described as an example in which a user's operation is received by a gesture, the user's operation may be acquired in various ways, not limited to a gesture. For example, the water discharge control system 1 may have an operation unit that receives the user's operation. Note that the operation unit may have any configuration as long as it can receive the user's operation, and may be a button provided on the kitchen main body 2, an operation panel, a remote control device, or the like. In this way, the water discharge control system 1 receives the user's operation in any way, and switches modes according to the received user operation.

[0155] Furthermore, the control unit 100 may transition to the power saving mode in response to a state in which the amount of change in the size and position of the detected object remains less than a predetermined amount for a predetermined period of time or more in the water discharge control mode. For example, if the amount of change in the size and position of the detected object remains less than a predetermined amount for a predetermined period of time or more, the control unit 100 may determine that the detected object has been placed and left unattended and transition to the power saving mode.

[0156] Furthermore, when a predetermined condition (mode switching condition) is satisfied in the power saving mode, the control unit 100 transitions to the water discharge control mode. For example, when the control unit 100 acquires a change in the state of the detected object in the power saving mode, the control unit 100 transitions to the water discharge control mode. Furthermore, when the control unit 100 acquires information on a new detected object in the power saving mode, the control unit 100 transitions to the water discharge control mode. For example, when the processing result using a model (AI) such as the above-mentioned learning model 134 satisfies a predetermined condition (mode switching condition), the control unit 100 transitions to the water discharge control mode.

[0157] Note that the control unit 100 may switch modes without using a model (AI) such as the learning model 134 described above. For example, the control unit 100 may transition to the water discharge control mode when, in the power saving mode, a change in the detection information by the image capture unit 10 that is greater than or equal to a predetermined value is acquired. For example, the control unit 100 transitions to the water discharge control mode when the processing result without using a model (AI) such as the learning model 134 described above satisfies a predetermined condition (mode switching condition). For example, the control unit 100 transitions to the water discharge control mode when the amount of change in the pixel value of a predetermined pixel is greater than or equal to a predetermined value. In this way, by transitioning to the water discharge control mode based on the change in pixel value, the control unit 100 can appropriately switch modes even when the brightness of the lighting, etc., changes.

[0158] In the power saving mode, the control unit 100 transitions to the water discharge control mode based on a change in the detection result by the imaging unit 10. For example, when there is a change in the detection result, the control unit 100 determines that use has started and transitions to the water discharge mode. For example, in the water discharge control mode, the control unit 100 controls the water discharge state using a model (AI) such as the learning model 134 that has learned the characteristics of the detected object.

[0159] The control unit 100 transitions to the power saving mode in response to a state in which there is no detected object continuing for a predetermined period of time or more in the water discharge control mode. The control unit 100 also transitions to the power saving mode in response to a state in which the amount of change in the size and position of the detected object is less than a predetermined amount continuing for a predetermined period of time or more in the water discharge control mode. Then, when the imaging unit 10 detects an object in the power saving mode, the control unit 100 transitions from the power saving mode to the water discharge control mode.

[0160] The control unit 100 acquires information including at least one of the size, type, distance from the water outlet, and position of the detected object as characteristic information of the detected object, and controls the water discharge stop using the acquired characteristic information. In the water discharge control mode and power saving mode, the control unit 100 controls the water discharge from the water discharge unit 30 based on the detection result of the imaging unit 10.

[0161] <1-5-2. Example of a mode that includes multiple power saving modes> The water discharge control mode and power saving mode described above are merely examples of modes, and the control unit 100 may have modes other than the water discharge control mode and the power saving mode. For example, the control unit 100 may have a second power saving mode that consumes even less power than the power saving mode. This point will be explained using FIG. 7. Fig. 7 is a diagram showing an example of a mode including a plurality of power saving modes. Mode information MD2 in Fig. 5 shows a case where the water discharge control system 1 has a water discharge control mode, a power saving mode, and a second power saving mode, and switches between the water discharge control mode, the power saving mode, and the second power saving mode.

[0162] For example, when a predetermined time or more has passed since the control unit 100 switched from the water discharge control mode to the power saving mode in the power saving mode, the control unit 100 switches to the second power saving mode. When the control unit 100 acquires a predetermined or greater change in the detection information from the image capture unit 10 in the second power saving mode, the control unit 100 switches to the water discharge control mode. Furthermore, when the absence of a detected object continues for a predetermined time or more in the water discharge control mode, the control unit 100 switches to the power saving mode.

[0163] Furthermore, the control unit 100 may transition to the power saving mode in response to a user operation (also referred to as a "second operation"). Note that the second operation is the same as the first operation except for the mode to which the mode is transitioned, and therefore detailed description will be omitted. For example, the control unit 100 acquires information indicating a second operation by the user that instructs transition to the second power saving mode (second operation information), and transitions to the second power saving mode based on the acquired second operation information. For example, the control unit 100 may acquire the second operation information by acquiring an image including a gesture by the user from the imaging unit 10 and analyzing the acquired image.

[0164] In the water discharge control mode, the control unit 100 may transition to a second power saving mode, which consumes even less power than the power saving mode, in response to the control unit 100 acquiring predetermined second operation information. Note that, like the first operation, the second operation information may be acquired in various ways, not limited to a gesture. For example, the second operation information may be acquired by an operation unit that accepts a user's operation. Note that the second power saving mode may execute processing in any way as long as it consumes less power than the power saving mode. For example, the second power saving mode may consume less power than the power saving mode by setting a longer time interval than the power saving mode. Furthermore, for example, the second power saving mode may consume less power than the power saving mode by using a model that consumes less power than the power saving mode, or by performing processing without using a model.

[0165] <1-5-3. Time interval example> Next, an example of the relationship between modes and time intervals shown in Figure 8 will be described. Figure 8 is a diagram showing an example of time intervals in each mode. Note that explanations of points similar to those described above will be omitted where appropriate. For example, the water discharge area WA1 in Figure 8 is similar to the water discharge area WA1 described above, and therefore explanations will be omitted.

[0166] The first time interval shown at the top of Fig. 8 corresponds to the time interval for detection in the water discharge control mode, and the second time interval shown at the bottom of Fig. 8 corresponds to the time interval for detection in the power saving mode. The first time interval indicates a case where detection is performed at times t1 to t7, as shown in images FR11 to FR15, etc. The second time interval indicates a case where detection is performed at times t1, t3, t5, and t7, as shown in images FR21 to FR24, etc., but is not performed at times t2, t4, and t6. The detection time interval in the second power saving mode may also be the second time interval.

[0167] FIG. 8 shows a case where the second time interval in the power saving mode is twice the first time interval in the water discharge control mode. In this way, in the water discharge control system 1, the time interval for detecting the presence or absence of an object in the power saving mode is set to be longer than the time interval in the water discharge control mode. As a result, in the water discharge control system 1, the power saving mode consumes less power than the water discharge control mode. The water discharge control system 1 may reduce the power consumption in the power saving mode by reducing the number of detections. Note that the above-mentioned time interval may be the interval for capturing images by the imaging unit 10, or the interval for processing using the images.

[0168] Furthermore, the control unit 100 may set different water discharge start conditions in the water discharge control mode and the power saving mode based on the detection results of the imaging unit 10. An example of this point will be described below.

[0169] For example, the water discharge start condition in the water discharge control mode may be that a detected object is located in the water discharge area WA1 for three consecutive frames. In this case, in the water discharge control mode, if a detected object is located in the water discharge area WA1 for three consecutive frames, the control unit 100 will determine that the water discharge start condition is met and will start water discharge. Note that three frames is just one example, and the water discharge start condition in the water discharge control mode can be set arbitrarily, for example, to five frames.

[0170] For example, the water discharge start condition in the power saving mode may be that a detected object is located in the water discharge area WA1 for two consecutive frames. In this case, in the power saving mode, when a detected object is located in the water discharge area WA1 for two consecutive frames, the control unit 100 determines that the water discharge start condition is met and starts water discharge.

[0171] In this way, if the same water discharge start conditions as in the water discharge control mode are used in the power saving mode, the time until water discharge will be delayed. Therefore, the water discharge control system 1 differs the water discharge start conditions in the power saving mode from the water discharge start conditions in the water discharge control mode, for example by reducing the number of consecutive frames in the conditions, thereby suppressing delays in the power saving mode and enabling appropriate control of water discharge stop. Note that two frames is just one example, and the water discharge start conditions in the power saving mode can be set arbitrarily. In this way, the water discharge start conditions based on the detection results may be different in the water discharge control mode and the power saving mode.

[0172] <1-6. Processing examples in each mode> Below, we will explain examples of processing that the water discharge control system executes in each of the water discharge control mode (control mode) and the power saving mode. Note that, although the following explanation will be made with the water discharge control system 1 as the processing subject, the first to third processes may be executed by any device, such as the control unit 100 or various sensors such as the imaging unit 10, depending on the device configuration included in the water discharge control system 1.

[0173] <1-6-1. Processing flow in water discharge control mode> First, the flow of processing related to the processing in the water discharge control mode will be described with reference to Fig. 9. Fig. 9 is a flowchart showing an example of the procedure related to the processing in the water discharge control mode executed by the water discharge control system.

[0174] The water discharge control system 1 executes the process of image acquisition #1 (step S101). For example, the control unit 100 executes the first image acquisition program 131, and receives from the imaging unit 10 the image captured by the imaging unit 10 based on the time interval for acquiring the image, the size of the image, and the like, which are specified in the first image acquisition program 131.

[0175] Then, the water discharge control system 1 executes the model (step S102). For example, the control unit 100 executes the learning model 134 using the learning model execution program 133. Then, the control unit 100 executes the following processing based on the processing results of the learning model 134. For example, the control unit 100 executes the following processing using the processing results of the learning model 134 and the water discharge control program 135.

[0176] The water discharge control system 1 determines whether or not a detectable object has been detected in the water discharge area (step S103). If the water discharge control system 1 determines that a detectable object has been detected in the water discharge area (step S103: Yes), it determines whether or not the detected object is specific information (step S104). For example, the control unit 100 determines whether or not the detected object detected in the water discharge area is an object other than the object to be discharged.

[0177] If the water discharge control system 1 determines that the detected object is not specific information (step S104: Yes), it determines whether the change in size and position of the detected object is greater than or equal to a predetermined value (step S105). For example, if the control unit 100 determines that the detected object is not an object other than the object to be discharged, that is, that the detected object is the object to be discharged, it determines whether the change in size and position of the detected object is greater than or equal to a predetermined value.

[0178] When the water discharge control system 1 determines that the change in size and position of the detected object is greater than or equal to a predetermined amount (step S105: Yes), it performs a water discharge determination (step S106). For example, when the control unit 100 determines that the change in size and position of the detected object is greater than or equal to a predetermined amount, it performs a water discharge determination using information such as the classification, size, and amount of change in position of the object to be discharged. For example, the control unit 100 determines (determines) the water discharge state using information such as the classification, size, and amount of change in position of the object to be discharged, which is the detected object.

[0179] Then, the water discharge control system 1 executes control of stopping water discharge according to the determination, and continues the water discharge control mode (step S107). For example, the control unit 100 controls the water discharge unit 30 in a water discharge state determined based on the classification, size, and amount of change in position of the object to be discharged, and continues the water discharge control mode.

[0180] When the water discharge control system 1 determines that the amount of change in the size and position of the detected object is not greater than a predetermined amount (step S105: No), it determines whether the waiting time is greater than a predetermined amount (step S108). For example, when the control unit 100 determines that the amount of change in the size and position of the detected object is not greater than a predetermined amount, it determines whether the waiting time is greater than a predetermined amount.

[0181] When the water discharge control system 1 determines that the standby time is equal to or longer than a predetermined time (step S108: Yes), it stops the water discharge and transitions to the power saving mode (step S109). For example, when the control unit 100 determines that the standby time is equal to or longer than a predetermined time, it controls the water discharge unit 30 to stop the water discharge and transitions to the power saving mode.

[0182] When the water discharge control system 1 determines that the waiting time is not equal to or longer than the predetermined time (step S108: No), it performs a water discharge determination (step S110). Then, the water discharge control system 1 executes control of stopping water discharge according to the determination, and continues the water discharge control mode (step S111).

[0183] When the water discharge control system 1 determines that the detected object is specific information (step S104: No), it stops the water discharge and transitions to power saving mode (step S113). For example, when the control unit 100 determines that the detected object is an object other than the object to be discharged, it controls the water discharge unit 30 to stop the water discharge and transitions to power saving mode.

[0184] When the water discharge control system 1 determines that the object to be detected is not detected in the water discharge area (step S103: No), it determines whether the waiting time is equal to or longer than a predetermined time (step S112). For example, when it determines that the amount of change in the size and position of the object to be detected is not equal to or longer than a predetermined time, the control unit 100 determines whether the waiting time is equal to or longer than a predetermined time.

[0185] When the water discharge control system 1 determines that the standby time is equal to or longer than a predetermined time (step S112: Yes), it stops the water discharge and transitions to the power saving mode (step S113). For example, when the control unit 100 determines that the standby time is equal to or longer than a predetermined time, it controls the water discharge unit 30 to stop the water discharge and transitions to the power saving mode.

[0186] If the water discharge control system 1 determines that the standby time is not equal to or longer than the predetermined time (step S112: No), it stops the water discharge and continues the water discharge control mode (step S113). For example, if the control unit 100 determines that the standby time is not equal to or longer than the predetermined time, it controls the water discharge unit 30 to stop the water discharge and continues the water discharge control mode (step S114).

[0187] <1-6-2. Processing flow in power saving mode> Next, the flow of processing related to processing in power saving mode will be described using Fig. 10. Fig. 10 is a flowchart showing an example of the procedure related to processing in power saving mode executed by the water discharge control system. Note that explanations of points similar to those explained in Fig. 9 will be omitted as appropriate.

[0188] The water discharge control system 1 executes the process of image acquisition #2 (step S201). For example, the control unit 100 executes the second image acquisition program 132, and receives from the imaging unit 10 the image captured by the imaging unit 10 based on the time interval for acquiring the image, the size of the image, and the like, which are specified in the second image acquisition program 132.

[0189] Then, the water discharge control system 1 executes the model (step S202). For example, the control unit 100 executes the learning model 134 by the learning model execution program 133. Note that the learning model 134 used in step S202 may be a model that consumes less power than the learning model 134 used in step S102.

[0190] The water discharge control system 1 determines whether or not a detectable object has been detected (step S203). For example, the control unit 100 determines whether or not a detectable object has been detected in the water discharge area. If the water discharge control system 1 determines that a detectable object has been detected (step S203: Yes), it determines whether or not the amount of change in the size and position of the detected object is greater than or equal to a predetermined amount (step S204). For example, if the control unit 100 detects a detectable object in the water discharge area, it determines whether or not the amount of change in the size and position of the detected object is greater than or equal to a predetermined amount.

[0191] When the water discharge control system 1 determines that the change in size and position of the detected object is equal to or greater than a predetermined value (step S204: Yes), it performs a water discharge determination (step S205). Then, the water discharge control system 1 executes control of stopping water discharge according to the determination, and transitions to water discharge control mode (step S206). For example, the control unit 100 controls the water discharge unit 30 in a water discharge state determined based on the classification, size, and change in position of the object to be discharged, and transitions to the water discharge control mode.

[0192] If the water discharge control system 1 determines that the amount of change in the size and position of the detected object is not greater than a predetermined amount (step S204: No), it stops the water discharge and continues the power saving mode (step S207). For example, if the control unit 100 determines that the amount of change in the size and position of the detected object is not greater than a predetermined amount, it controls the water discharge unit 30 to stop the water discharge and continues the power saving mode.

[0193] When the water discharge control system 1 determines that the object to be detected has not been detected (step S203: No), it stops the water discharge and continues the power saving mode (step S207). For example, when the control unit 100 does not detect the object to be detected in the water discharge area, it controls the water discharge unit 30 to stop the water discharge and continues the power saving mode.

[0194] <1-8. Examples of ways to reduce power consumption> Note that the above-described method of reducing power consumption in the power saving mode compared to the water discharge control mode is merely one example, and any method of reducing power consumption can be adopted as long as the power consumption in the power saving mode is less than the power consumption in the water discharge control mode. Several methods of reducing power consumption will be explained using Figure 11. Figure 11 is a diagram showing an example of a method of reducing power consumption.

[0195] 11 shows an example of a method for reducing power consumption for each software (program), such as an image acquisition program, a model execution program, an object detection program (learning model), a water discharge control program, etc. Note that explanations of points similar to those described above will be omitted where appropriate.

[0196] When reducing power consumption by an image acquisition program, the water discharge control system 1 may reduce power consumption by increasing the time interval for acquiring images. For example, the water discharge control system 1 may reduce power consumption by reducing the number of images processed per hour, such as by changing from 30 FPS (Frames Per Second) to 15 FPS, thereby reducing the amount of calculation.

[0197] Furthermore, when reducing power consumption using an image acquisition program, the water discharge control system 1 may reduce power consumption by reducing the image size. For example, the water discharge control system 1 may reduce the amount of calculations and reduce power consumption by reducing the size of the image to be processed, such as by changing the image size from 320 x 320 to 160 x 160.

[0198] Furthermore, when reducing power consumption using an image acquisition program, the water discharge control system 1 may reduce power consumption by reducing the color information of the image. For example, the water discharge control system 1 may reduce power consumption by reducing the amount of calculation by reducing the color information of the image, such as by changing from RGB to black and white.

[0199] When reducing power consumption by using a model execution program, the water discharge control system 1 may reduce power consumption by increasing the time interval at which the model is executed. For example, the water discharge control system 1 may reduce power consumption by reducing the amount of calculations by increasing the execution time interval, such as changing from 10 FPS to 5 FPS.

[0200] When reducing power consumption using a learning model such as an object detection program, the water discharge control system 1 may reduce power consumption by switching the learning model. For example, the water discharge control system 1 may reduce the amount of calculation and reduce power consumption by switching to a model with a low amount of calculation, such as changing from the default model (normal model) to a model (power-saving model) with fewer learnable features (number of parameters).

[0201] When reducing power consumption by the water discharge control program, the water discharge control system 1 may reduce power consumption by increasing the time interval for processing the water discharge control. For example, the water discharge control system 1 may reduce power consumption by reducing the amount of calculations by increasing the time interval for determining water discharge, such as by changing from 30 FPS to 15 FPS.

[0202] Furthermore, when reducing power consumption by the water discharge control program, the water discharge control system 1 may reduce power consumption by switching the water discharge control program. For example, the water discharge control system 1 may reduce the amount of calculation and reduce power consumption by switching to a program with lighter processing, such as changing from the default (normal determination conditions) to determination conditions with fewer determination conditions (power-saving determination conditions).

[0203] It should be noted that the power consumption reduction method shown in FIG. 11 is merely an example, and any method can be adopted as the power consumption reduction method.

[0204] <2. Other configuration examples> The device configuration of the water discharge control system 1 shown in FIG. 2 is merely an example, and the water discharge control system 1 can adopt any device configuration. The water discharge control system 1 can be applied to various configurations as long as it is capable of executing at least some of the processes described above. For example, the water discharge control system 1 may be applied to a configuration in which purified water is controlled to be discharged separately from cold water and hot water. An example of the configuration of the water discharge control system 1 in this case will be explained using FIG. 12. FIG. 12 is a diagram showing an example of another configuration of the water discharge control system.

[0205] Figure 12 shows an example in which purified water is supplied to water discharger 30 from a system separate from that for raw water and hot water. In the configuration example shown in Figure 12, water discharge control system 1 includes water purifier 82 that purifies raw water supplied from water supply 80 via water purification valve 102. In this case, purified water is discharged from water discharger 30 in response to operation of water purifier 82 by the user. For example, water discharge control system 1 may control water discharge for only two types of water, raw water and hot water.

[0206] <3. Other embodiments> The water discharge control system 1 described above is merely an example, and the control system may be a system that controls various plumbing devices as control targets.

[0207] In the above-described embodiment, the water discharge control system 1 has been described as being applied to a kitchen, but it can be applied to any wet space where utensils can be used, for example, a wash area in a toilet space or a vanity where water discharge and stopping actions such as hand washing are performed.

[0208] Furthermore, the water discharge control system 1 is merely one example of a control system for controlling plumbing equipment, and the control system may perform various controls of plumbing equipment other than controlling water discharge and stop. That is, the control system is not limited to the water discharge control system 1, and may be any system that performs at least one of determining the presence or absence of a detectable object or extracting characteristic information of the detectable object based on detection information from a detection unit that detects the detectable object in the plumbing equipment, and controls the plumbing equipment based on the determination result or extraction result. That is, the control system may be a system that controls any plumbing equipment as long as it has a power-saving mode that reduces power consumption in the control unit and a control mode that increases power consumption in the control unit compared to the power-saving mode and controls the plumbing equipment based on the detection result of the detection unit.

[0209] Note that the plumbing equipment referred to here is not limited to equipment that handles water (liquid), but may also include equipment attached to a plumbing area, as long as it is an object (equipment, etc.) that the control system can control. For example, the water discharge control system 1 may control lighting fixtures and the like installed in a plumbing space as plumbing equipment by switching between a control mode and a power saving mode in the same manner as the above-described process. In other words, the control system can be applied to control any plumbing equipment as long as it controls a control object installed in a plumbing space.

Further effects and modifications can be easily derived by those skilled in the art. Therefore, the broader aspects of the present invention are not limited to the specific details and representative embodiments shown and described above.
