Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The human body sensing technology is a technology for judging whether the whole human body and a certain part of the human body are located in a preset target area. The human body sensing technology can judge the motion condition and position of the whole human body, and can judge whether a certain part of the human body performs a certain action or is located in a preset target area.
Human body sensing technology is now being applied to various technical fields. For example, the human body sensing technology can be used in a user's house or a merchant store for real-time learning of guest or user entry; for another example, the human body sensing technology can also be used in the technical field of game entertainment, and entertainment equipment or electronic game scenes can be controlled by identifying human body parts; for example, human body sensing technology can be used in the field of electrical appliances, for example, when a human hand is sensed to be in a target area, a water heater can start to flow hot water; when the fact that the hands leave the target area is sensed, the water heater can control the hot water to stop flowing out. The human body sensing technology provides more intelligent control and interaction modes for human-computer interaction.
In the prior art, the human body induction technology mainly utilizes an infrared sensor, a microwave sensor or an ultrasonic sensor to realize the induction of the human body. However, the human body induction technology in the prior art has the following problems: when people need to respond to a large-range target area, a plurality of sensors need to be added due to the fact that the effective detection distance of a single infrared sensor, a single microwave sensor or a single ultrasonic sensor is limited, and a sensor matrix is formed by the sensors to respond to the large-range target area, so that the technical problem of high economic cost can be caused; when accurate human body induction needs to be carried out on a determined target area, the detection range of the infrared sensor, the microwave sensor or the ultrasonic sensor cannot be accurately limited, and when a human body exists around the determined target area, the false recognition of the sensor can be generated.
In order to solve at least one technical problem, embodiments of the present invention provide a human body detection device, a water supply apparatus, and a method, where the human body detection device detects whether a human body is present in an area to be detected based on a capacitance measurement chip and a lead wire that is disposed around the area to be detected and connected to an input end of the capacitance measurement chip. The human body detection device solves the technical problems of low precision and high cost of the human body detection technology in the existing human body detection technology, and has the beneficial effects of carrying out human body detection accurately and at low cost.

the control unit A1 is used for confirming whether human body appears in the area A4 to be detected based on the capacitance value of the capacitor A3, and the control unit A1 is in communication connection with the output end of the capacitance measuring chip.
The input end of the capacitance measuring chip A2 is connected with the capacitor A3 and used for receiving capacitance change signals, and the output end of the capacitance measuring chip A2 is connected with the control unit A1 so that the control unit A1 can judge whether a human body appears in the area A4 to be detected based on the capacitance change signals.
Further, a capacitor A3 is provided around the area a4 to be detected, and is configured such that the capacitance value of the capacitor A3 changes if a human body is present in the detection area. When no human body is present in the region a4 to be detected, the capacitor A3 generates a parasitic capacitance Cp; when the human body approaches any position in the area a4 to be detected, the human body forms a capacitance to ground, and thus the capacitance value becomes larger in parallel with the parasitic capacitance Cp on the capacitor A3. The position where the capacitor a3 is provided is not particularly limited, and may be any position as long as the capacitance value of the capacitor changes when a human body is present in the detection area.
Further, the capacitance measuring chip a2 can be any type and model of capacitance measuring chip in the prior art, as long as the capacitance change signal can be collected and sent to the control unit for processing.
Still further, the control unit can be a unit having data processing and signal control, such as an MCU, a CPU, a single chip microcomputer, or any type and type of processing unit in the prior art, as long as the capacitance change signal can be received, and whether a human body exists in the region to be detected a4 can be determined based on the capacitance change signal.
The human body in the embodiment of the present invention may be the entire limb of a human body, or may be a part of a limb, such as a hand, a foot, a head, and the like.

On the basis of any of the above embodiments of the present invention, as shown in fig. 7, an overall flow chart of a water supply control method using the above water supply equipment is shown, which includes:
s31, detecting that the capacitance value of the capacitor is larger than the initial value; the initial value is a capacitance value between the first lead and the second lead when no human body exists in the region to be detected;
and S32, controlling the water valve to keep an open state.
As shown in fig. 2, the first lead is disposed around the water receiving area of the water supply device, the second lead is grounded, and the second lead is disposed around the outer ring of the first lead. When no human body appears in the water receiving area of the water supply equipment, a parasitic capacitance Cp is generated between the first lead and the second lead, and the value of Cp is recorded; when a human body is close to any position outside a water receiving area of the water supply equipment, the second lead of the outermost ring is grounded, so that the shielding effect is achieved, the capacitance cannot be changed, and the false detection is prevented.
Further, the capacitance measuring chip collects capacitance values in real time and sends the capacitance values to the control unit.
Still further, the control unit receives the capacitance value, and if the capacitance value is larger than Cp, the control unit determines that a human body exists in the water receiving area of the water supply equipment at the moment. The control unit sends out a control signal to control the water valve to keep an open state.
The embodiment of the invention provides a water supply control method, which detects that the capacitance value of a capacitor is larger than an initial value; the water valve is controlled to keep an open state. The water supply control device solves the technical problems of low precision and high cost of the human body detection technology in the existing human body detection technology, and has the beneficial effects of accurate and low-cost water supply control.
On the basis of any one of the above embodiments of the present invention, there is provided a water supply control method, further including:
s31', detecting that the capacitance value of the capacitor changes from being greater than the initial value to being equal to the initial value;
s32', the water valve is controlled to change from the open state to the closed state.
When the control unit detects that the capacitance value between the first lead and the second lead is changed from being larger than Cp to being equal to Cp, the control unit judges that the hand of a user in the water receiving area of the water supply equipment is pulled away, at the moment, the default judgment is made that the user wants to stop receiving water, the water receiving container is taken away from the designated position on the water receiving platform, and the control unit controls the water valve to be closed.
