Then, carry out the explanation of the action of the water system 1 of embodiments of the present invention.Fig. 4 is the flow chart that represents the treatment step of condition judgement processing.Below, use Fig. 4 that the condition judgement processing that water system 1 is carried out is described.
First,, in step SP100, video camera 30 is taken the image of the region A1 that discharges water.The region A1 that discharges water has comprised the region of carrying out from the scope discharging water of feed water inlet 23.
In the case of the water supply installation 20 shown in Fig. 2, the region A1 that discharges water expands below water tap 22, and be generally in the time that user wants to utilize from the discharging water of feed water inlet 23, the region that user enters the object (cup that this user's hand or this user are hand-held etc.) discharging water.
In addition, video camera 30 is as CCD(Charge Coupled Device: charge coupled cell) device that can obtain image (live image) of general video camera video camera and the solid-state imager taking ccd image sensor or cmos image sensor as representative etc., can obtain the device of the image data of taking the region A1 that discharges water.
And image obtaining section 11 is used signal S1 and obtains the image data of taking the region A1 that discharges water from video camera 30.The image format such as compress mode or bit rate of this image data does not limit in the present invention, needs only the state that can explore the object discharging water or judge this object in step SP110 described later and step SP120.
In addition, except the structure shown in Fig. 1, water system 1 can also comprise storage device, and image obtaining section 11 also can be stored this image data in this storage device.And image obtaining section 11 uses signal S2 and image data (also can comprise the image data in the past of memory device stores) that video camera 30 is taken is exported to detection unit 12.
Then, with reference to Fig. 4, in step SP110, detection unit 12 is by the image data of the region A1 that discharges water based on shooting, explores the object discharging water, thereby judges and in the A1 of region, have or not this object discharging water.
Specifically, the detection unit 12 that has been transfused to the image data of taking the region A1 that discharges water has used to the image of this image data the MARG obtaining by edge extracting or has passed through the object identification processing such as pattern match of the characteristic that feature point extraction obtains.As this object identification processing, can use the image recognition technology of carrying out in general image is processed.In detection unit 12, the reference data that registration in advance is relevant with edge or the characteristic point etc. of the object discharging water.
Therefore, detection unit 12 is by this object identification processing, judges that the object that mates with the reference data of the object of registration in advance is whether discharging water in the A1 of region, thereby can explore the object discharging water in the A1 of region discharging water.
The object discharging water in the present invention is for example for the cook utensil of drinking container and pot or the kettle etc. of face-washing appliance, the cup etc. of hand, toothbrush etc. as user's people etc., as long as generally receive from water supply installation the object discharging water.
In addition, except these objects, as long as the object that can identify by object identification processing, even if be not generally to receive the object discharging water, also can be as the object discharging water by registering in advance.
And, in the region A1 that discharges water carrying out at detection unit 12, have or not in the judgement of object, the object discharging water is (that is, the result of determination in step SP110 is "Yes") in the situation that discharging water in the A1 of region, and water system 1 is carried out the action of step SP120 described later.In addition, on the other hand, the in the situation that of in the object discharging water or not region A1 (that is, the result of determination in step SP110 is "No"), water system 1 is carried out the action of step SP115 described later.
In the judgement of step SP110, be judged to be "No", in step SP115, detection unit 12 does not have the decision signal S3 of the information of finding the object discharging water to export to control part 13 by comprising.Further, control part 13, based on this decision signal S3, is exported the control signal S4 not discharging water to feed water valve 21.Feed water valve 21, according to this control signal S4, does not carry out discharging water from water supply installation 20.
In addition, in the situation that water supply installation 20 does not discharge water originally, also can be in step SP115, control part 13 is not exported control signal S4.And, the water system 1 done state determination processing of the action of the step that is through with SP115.
In the judgement of step SP110, be judged to be "Yes", in step SP120, detection unit 12 is judged the state of this object.For example, for the judgement of the state of the object discharging water, it can be also the judgement whether detection unit 12 is judged the MARG of this object that the image data that photographs from video camera 30 obtains or characteristic, met with the data of relevant normal condition with the predetermined state of object of registration in advance detection unit 12.
In addition, the MARG of object in the image that detection unit 12 can photograph based on video camera 30 or the time of characteristic change, and obtain the action data of object.By judging whether the action data of this object meets with the data of the relevant benchmark action with predetermined action object registration in advance in detection unit 12, thereby detection unit 12 can be judged the action whether this object is scheduled to.
For the predetermined state of the object of this registration in advance, also can be in the case of for example as the object that discharges water and registrant's hand, " palm is towards the state of the direction of feed water inlet 23 " of the state discharging water as needs, as require to increase waterdrainage amount state " only stretched out the state (state of the scissors form of so-called finger-guessing game) of two fingers and as " close finger and clench fist state " etc. of state that requires to reduce waterdrainage amount.
In addition, register cup at the object as discharging water, this predetermined state can be also " mouth of cup is towards the state of the direction of feed water inlet 23 " of the state that discharges water as needs.In addition for the predetermined action of the object of registration in advance, can be also the hand of the registrant at the object as discharging water, as " action of spreading hand cleanser and rubbing both hands " of the sliding action of hand.
In addition, each object that also can register the object as discharging water, registers and relevant predetermined state and the predetermined action of discharging water.In step SP120, judge by detection unit 12 whether object meets state and the action of these registrations.
Then,, in step SP130, detection unit 12 judges whether water system 1 monitors in the execution of processing as described later washing one's hands.Monitor in the executory situation of processing (that is, the result of determination in step SP130 is "Yes") for washing one's hands in water system 1, water system 1 is processed the supervision of washing one's hands of carrying out to continue, done state determination processing.
In addition, on the other hand, not to wash one's hands to monitor in the executory situation of processing (that is, the result of determination in step SP130 is "No") in water system 1, in step SP140, water system 1 is carried out described later discharging water and is controlled the action of processing.
In addition, always process from step SP100 to condition judgement shown in step SP140 or every predetermined interval (for example 0.2 second interval etc., for detection of the suitable interval of entering of the object discharging water in the A1 of region) repeat.
Therefore, water system 1 judgement of the detection of the object in the A1 of region and the state of this object that can suitably discharge water.In addition, even monitor that described later washing one's hands, in the execution of processing, condition judgement is processed and also repeated, the result of determination of the state of the object carrying out in condition judgement is processed can be monitored and processes for washing one's hands.
