Referring to fig. 1, fig. 7 and fig. 8 in combination, fig. 1 is a flowchart of a toilet control method according to an embodiment of the present invention, and fig. 7 and fig. 8 are schematic diagrams of a toilet according to an embodiment of the present invention. The radar-based toilet bowl control method is used for controlling the toilet bowl 1000 during the use of the toilet bowl 1000 by a user. In the present embodiment, the radar 110 is provided to the toilet 1000. The toilet 1000 includes a toilet body 300 and a toilet cover 200 connected to each other, and the radar 110 is a millimeter-wave radar. The radar-based toilet control method specifically comprises the following steps.
And S102, detecting the detection range by using a radar and acquiring an echo signal. The method utilizes the main control device 120 electrically connected with the radar 110 to control the radar 110 to detect the detection range A. When the radar 110 detects, electromagnetic waves are emitted outward. When an electromagnetic wave hits an object, the object reflects the electromagnetic wave to form an echo signal, which is received by the radar 110. Wherein, the detection range A is a range of 30 centimeters away from the edge of the toilet 1000. In some possible embodiments, the distance of the detection range a may be any value between 20 cm and 50 cm, and is not limited herein. In other possible embodiments, the detection range a may be a circular range or a square range centered on the toilet 1000, or the like. The size, shape, and the like of the detection range a may be set by default at the time of factory shipment, or may be set by the user according to the use habit, which is not limited herein.
And step S104, judging whether a detection target exists in the detection range according to the echo signal. The method utilizes the master control device 120 to perform the determination according to the echo signal. Since the echo signals formed by the reflection of different objects are different, the main control device 120 may extract the characteristic values in the echo signals for judgment. Wherein, the detection target is set as a human body. When the feature value in the echo signal belongs to a human body, the main control device 120 considers that a detection target exists in the detection range a. Further, when the main control device 120 detects that the feature value in the echo signal belongs to a human body, it is continuously detected that the echo signal includes the feature value belonging to the human body within a preset time, and it is determined that the detection target exists within the detection range a. Otherwise, judging that no detection target exists in the detection range A. That is, the user needs to stay within the detection range a for a preset time before the main control device 120 considers that the user wants to use the toilet 1000. In the present embodiment, the preset time is 3 seconds. In some possible embodiments, the preset time may be any value between 2 and 5 seconds, and is not limited herein.
And S106, controlling the toilet cover body to be opened when the detection target exists in the detection range. When the detection target exists in the detection range A, the method controls the toilet lid 200 to be opened by using the main control device 120. In the present embodiment, the toilet cover 200 includes a first cover 210 and a second cover 220. The second cover 220 is disposed between the toilet body 300 and the first cover 210. The first cover 210 is a toilet lid, and the second cover 220 is a toilet seat. That is, when the detection target exists in the detection range a, the main control device 120 controls both the first cover 210 and the second cover 220 to be opened.
In this embodiment, step S106 specifically includes the following sub-steps (as shown in fig. 2).
And step S1061, controlling the first cover body to be opened when the detection target exists in the detection range. When the detection target exists in the detection range a, the method controls the first cover 210 to be opened by using the main control device 120 (as shown in fig. 5 a).
Step S1063, determining whether the echo signal contains the first gesture information. The method utilizes the main control device 120 to determine whether the first gesture information exists in the echo signal.
And step S1065, controlling the second cover body to open when the first gesture information exists in the echo signal. When the first gesture information exists in the echo signal, the main control device 120 controls the second cover 220 to open (as shown in fig. 5 b). In the present embodiment, the first gesture corresponding to the first gesture information is that the arm is lifted up in a direction perpendicular to the lowered toilet cover 200. That is, when the user makes an action of raising the arm upward in the vertical direction within the detection range a, the main control device 120 controls the second cover 220 to be opened. The first gesture may be set in advance when the device leaves a factory, or may be set by a user. Further, when the user sets the first gesture by himself, the user can set the first gesture according to the behavior habit of the user. That is, the first gesture may be another gesture, such as a waving of an arm in a direction parallel to the lowered toilet lid 200, which is not limited herein.
In some possible embodiments, after the main control device 120 controls the first cover 210 and the second cover 220 to be opened, the main control device 120 may further determine whether the echo signal includes third gesture information. When the third gesture information exists in the echo signal, the main control device 120 controls the second cover 220 to be put down. In the present embodiment, the third gesture corresponding to the third gesture information is that the arm falls down in a direction perpendicular to the lowered toilet lid 200. That is, when the user makes an action of dropping the arm in the vertical direction within the detection range a, the main control device 120 controls the second cover 220 to be lowered. The third gesture may also be set according to the behavior habit of the user, which is not limited herein.
Referring to fig. 1 again, in step S108, it is determined whether water flows exist in the detection range according to the echo signal. The method utilizes the master control device 120 to perform the determination according to the echo signal. In this embodiment, the main control device 120 detects the echo signal according to the doppler effect, and determines whether water current exists in the detection range a. Further, the main control device 120 determines whether water flows exist within the preset range B according to the echo signal. In the present embodiment, the preset range B is a range of the opening of the toilet body 300 (as shown in fig. 8).
And step S110, controlling the toilet to flush when water flow exists in the detection range and the water flow disappears according to the echo signal. After determining that water flow exists in the detection range a according to the echo signal, the main control device 120 determines whether the water flow disappears according to the echo signal. When the water flow disappears, the main control device 120 controls the toilet 1000 to flush. It will be appreciated that when water flow is present within the detection range a, this is indicative of a user using the toilet 1000. When the water flow disappears, namely the water flow does not exist in the detection range A, the user is indicated to finish using the water flow. At this time, the main control device 120 controls the toilet 1000 to flush.
And step S112, controlling the toilet cover body to be put down when the detection target does not exist in the detection range. When there is no detection target within the detection range a, the method controls the toilet lid 200 to be lowered using the main control device 120. In this embodiment, when the first cover 210 and the second cover 220 are both opened, the main control device 120 controls the first cover 210 and the second cover 220 to both be put down; when only the first cover 210 is opened, the main control device 120 controls the first cover 210 to be lowered. It is understood that, when the detection target exists within the detection range a and then the detection target leaves the detection range a, the main control device 120 controls the toilet lid 200 to be lowered. If there is no detection target in the detection range a in the previous detection, the master device 120 does not need to perform any operation.
In the embodiment, the radar is used for detecting and judging according to the echo signal, so that the toilet cover body is controlled to be opened and put down and the toilet is flushed, the state of the toilet is automatically controlled, and the use convenience of the toilet is effectively improved. Meanwhile, the user does not need to touch the closestool by hands, the closestool can be controlled through gestures, and the health and safety of the user can be guaranteed. In addition, the toilet bowl cover body is controlled to be opened only when the detection target stays in the detection range for the preset time, and false triggering can be effectively prevented. When the water flow disappears, the toilet is controlled to flush, and the toilet is controlled to flush instead of detecting the water flow, so that the water resource can be saved.
Please refer to fig. 3, which is a second sub-flowchart of a toilet control method according to an embodiment of the present invention. After step S106 is executed, the toilet control method further includes the following steps.
In step S1071, the presence or absence of a pressure signal is detected by the pressure sensor. The method detects the presence of a pressure signal using a pressure sensor 130 electrically connected to the master control device 120. It is understood that only the first cover 210 is in the opened state at this time. When a user sits on the second cover 220, pressure is applied to the second cover 220 so that the pressure sensor 130 can detect a pressure signal. The pressure sensor 130 may be disposed on the second cover 220, or may be disposed on the toilet body 300, which is not limited herein. In this embodiment, after the pressure sensor 130 detects the pressure signal, the pressure signal may be transmitted to the main control device 120.
And step S1073, controlling the flushing of the toilet when the pressure signal exists. When the pressure signal is present, the method controls the toilet 1000 flushing using the master control device 120. Further, when the presence of the pressure signal is detected, the main control device 120 determines whether the pressure signal disappears. When the pressure signal disappears, the main control device 120 controls the toilet 1000 to flush. It will be appreciated that the pressure signal, when present, indicates that the user is using the toilet 1000, and when the pressure signal disappears, i.e., the user is no longer seated on the second cover 220, indicates that the user is finished using the toilet. At this time, the main control device 120 controls the toilet 1000 to flush.
In the above embodiment, whether the user sits on the second cover is determined by the pressure sensor, and if a pressure signal is generated, it indicates that the user is using the toilet. When the generated pressure signal disappears, the toilet is controlled to flush, and water resources can be effectively saved.
Please refer to fig. 4, which is a third sub-flowchart of a toilet control method according to an embodiment of the present invention. After step S110 or step S1073 is performed, the toilet control method further includes the following steps.
Step S201 determines whether the echo signal contains the second gesture information. The method determines whether the second gesture information exists in the echo signal by using the main control device 120.
And step S203, controlling the toilet to flush when the second gesture information exists in the echo signal. When the second gesture information exists in the echo signal, the method controls the toilet 1000 to flush by using the main control device 120. In the present embodiment, the second gesture corresponding to the second gesture information is a finger circling in a direction parallel to the lowered toilet cover 200. It can be understood that, after the main control device 120 controls the toilet 1000 to flush, if the user feels that the toilet 1000 needs to be flushed again, the user can control the toilet 1000 to flush again through a second gesture. The second gesture may be set in advance when the device leaves the factory, or may be set by the user. Further, when the user sets the second gesture by himself, the user can set the second gesture according to the behavior habit of the user. That is, the second gesture may be other gestures, such as a finger drawing a "Z" shape in a direction parallel to the lowered toilet cover 200, and the like, which is not limited herein.
In the embodiment, the user can control the toilet to flush through the second gesture without touching the toilet with hands, so that the health and safety of the user can be guaranteed.
Please refer to fig. 6, which is a schematic diagram of an internal structure of a radar module according to an embodiment of the present invention. The radar module 100 includes a radar 110 and a main control device 120, and the radar 110 is electrically connected to the main control device 120. The radar 110 and the main control device 120 may be integrally disposed or separately disposed, and are not limited herein. In this embodiment, the radar module 100 further includes a pressure sensor 130 electrically connected to the main control device 120. Accordingly, the pressure sensor 130 and the main control device 120 may be integrally provided or may be separately provided, and are not limited herein.
