Description

TECHNICAL FIELD

[0001] The present application relates to the field of intelligent bathroom technology, in particular to a method and device for controlling flushing of a toilet bowl, a storage medium, a urinal and a toilet. BACKGROUND

[0002] The existing millimeter wave or microwave induction probe mainly uses the Doppler principle to detect the dynamic action of the human body. The dynamic induction detection is a detection method that uses the Doppler phenomenon to detect the approach or away action of the human body, gesture action, etc. in a short distance, and then delays a certain time after detecting the human action by the program algorithm of the main control board as the detection of the confirmation time that the human body is still using the flushing device, so as to determine whether a person is using the flushing device. Then, when no human action is detected, the flushing valve is controlled to open and close to flush. This microwave dynamic induction method based on the Doppler principle is too sensitive. If it is applied to urination, when a person walks from the front urinal to the back urinal to urinate, the front urinal is easy to be misinduced by the human action and misflushed. Moreover, when the flushing valve device flushes, the flowing water flow is easy to be misinduced by the microwave induction device and continuously flushed by self-excitation induction. SUMMARY

[0065] In step 12, the determining whether the human body conforms to the urination behavior according to the distance and the included angle can include:

[0066] When the included angle between the left forearm and / or the right forearm of the human body and the center line of the human body is equal to or less than a preset first angle threshold, it is determined that the human body conforms to the urination behavior.

[0067] In an exemplary embodiment, the left forearm of the human body can include a left wrist key point and a left elbow key point, and the included angle can be an included angle between a line connecting the left wrist key point and the left elbow key point and the center line of the human body.

Figure 3 Exemplarily, the first angle threshold value can be 85 degrees. The first angle threshold value can also be determined according to actual conditions.

[0070] Exemplarily, the first angle threshold value can be 85 degrees. The first angle threshold value can also be determined according to actual conditions.

[0071] In step 12, the human body is determined to be in a urination behavior according to the distance and the included angle. The method can further include:

[0072] When the horizontal distance between the arm key point on the left arm and / or the right arm of the human body and the human body midline is equal to or less than the first distance threshold value, the human body is determined to be in a urination behavior.

[0074] Exemplarily, the arm key point can be a left wrist key point and a right wrist key point.

[0075] The first distance threshold value can be determined according to the distance between the left shoulder key point and the right shoulder key point.

[0076] Exemplarily, assuming that the distance between the left shoulder key point and the right shoulder key point is 90 cm, the first distance threshold value can be equal to 1 / 4 of the distance between the left shoulder key point and the right shoulder key point, that is, the first distance threshold value can be 22.5 cm.

[0077] In step 12, the human body is determined to be in a urination behavior according to the distance and the included angle. The method can further include:

[0078] Determining a first included angle between the left forearm of the human body and the human body midline and a second included angle between the right forearm and the human body midline;

[0079] When the first included angle and / or the second included angle is greater than a second angle threshold value, and when the difference between the first included angle and the second included angle is not greater than a third angle threshold value, the human body is determined to be in a urination behavior.

[0082] Exemplarily, whether the human body conforms to the urination behavior can be determined according to that the angle between the line connecting the left wrist key point and the left elbow key point and the midline of the human body is equal to or less than the preset first angle threshold value.

[0083] Exemplarily, whether the human body conforms to the urination behavior can be determined according to that the horizontal distance between the left wrist key point and the midline of the human body is equal to or less than the preset first distance threshold value.

[0088] When it is determined that the human body is in a urination state, the toilet is controlled to flush based on the human body leaving the urination area.

[0089] Exemplarily, it can be determined that the human body leaves the urination area when the distance between the human body and the toilet is greater than a preset third distance threshold. The third distance threshold can be set to 60 cm, or can be set to other values according to requirements, which are not limited herein.

[0090] Exemplarily, it can be determined that the human body leaves the urination area when the human body is not detected for the first time after it is determined that the human body is in a urination state. Other methods can also be used to determine that the human body leaves the urination area, which are not limited herein.

[0091] In step 12, in an exemplary embodiment, the distance and the included angle are used to determine whether the human body is in a urination state, and the flush control of the toilet can include:

[0092] When it is determined that the human body is in a urination state, the toilet is controlled to flush for the first time;

[0093] After the first flush, the toilet is controlled to flush for the second time based on the human body leaving the urination area.

[0094] The flush control method of the toilet of this embodiment can not only avoid toilet flushing errors caused by false sensing, but also make the toilet cleaner through multiple flushing.

[0098] In an exemplary embodiment, before the distance and the included angle between the forearm of the human body and the center line of the human body are obtained, it can be determined that the human body is in a front position of the toilet.

[0099] The determination that the human body is in a front position of the toilet includes:

[0100] If the distance between the body midline and the toilet reference position in the second direction is determined to be less than or equal to a preset second distance threshold according to the position of the body midline and the position of the toilet reference position, it is determined that the body is in the front position of the toilet.

[0101] The second direction is a direction extending left and right of the body.

[0102] Exemplarily, the toilet reference position can be the middle position of the toilet or the position of the sensing device for sensing the body information.

[0103] Exemplarily, assuming that the width of the urinal in the first direction is 40 cm, the preset second distance threshold can be 20 cm.

[0104] In this embodiment, before the distance and the included angle between the forearm of the body and the body midline are obtained, it can be determined that the body is in the front position of the toilet, and then whether the body conforms to the urination behavior is determined according to the obtained distance and the included angle between the forearm of the body and the body midline, so as to improve the accuracy of the determination result.

[0105] In an exemplary embodiment, determining that the body enters the urination area can include determining, according to detection data of the sensing device, that a key part of the body is detected and the shortest distance between the body and the sensing device is less than or equal to a preset third distance threshold, and then determining that the body enters the urination area. Exemplarily, the sensing device can be a laser radar or a millimeter wave radar. Exemplarily, the detection data is three-dimensional point cloud data. Three-dimensional point cloud data is a data format for representing a set of points in a three-dimensional space. Each point is usually composed of its spatial coordinates or other attributes such as color, normal vector, etc. Exemplarily, the sensing device can be arranged in the toilet or arranged outside the toilet, for example, the sensing device is installed on the wall surface near the urinal.

[0106] In some other exemplary embodiments, determining that the body enters the urination area can be determined according to the distance between the body and the toilet.

[0107] Exemplarily, when the sensing device is installed on the ceramic surface on the back side of the urinal, the position information of the sensing device can be the position coordinates (0, 0, 0). The distance between the body midline and the sensing device is less than or equal to the preset third distance threshold, which means that the projection of the body midline on the vertical plane of the toilet installation ground is located on the circumference of the circle with the position of the sensing device as the center and the third distance threshold as the radius. Generally, the projection of the body midline is located on the circumference of the urinal in the front direction or the side direction.
