Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. 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 application.
The embodiment of the application provides a sweeping route adjusting method of a sweeping robot, which can be applied to the sweeping robot, in particular to a control system of the sweeping robot. The sweeping robot can be provided with a plurality of millimeter wave radars (namely millimeter wave radar groups), and each millimeter wave radar can be deployed in a plurality of directions of the sweeping robot so as to realize 360-degree all-around detection of the sweeping robot. In the implementation, the specific setting position of the millimeter wave radar can be determined according to the detection range of the millimeter wave radar and the actual shape of the sweeping robot, and the embodiment of the application does not limit the setting position.
The method for adjusting the cleaning route of the cleaning robot provided by the embodiment of the present application will be described in detail with reference to specific embodiments, as shown in fig. 1, the specific steps are as follows:
In implementation, the sweeping robot may store a sweeping route in advance, the sweeping route may be preset by a user using the sweeping robot, and the user may further divide the sweeping route to obtain a plurality of sweeping areas, where the sweeping areas may be a kitchen, a bedroom, a study room, and the like.
The sweeping robot can take the current sweeping area as the area to be swept in the sweeping process according to the sweeping route, and then millimeter wave radars deployed on the sweeping robot can emit millimeter waves to the area to be swept.
And 102, determining detection object information in the area to be cleaned based on the received millimeter wave echo signal.
In implementation, the sweeping robot may receive the echo signal of the millimeter wave, and then, the sweeping robot may analyze the echo signal to obtain the information of the detection object in the area to be swept.
In the embodiment of the present application, the detection object information may be various, and in a feasible implementation manner, the detection object information may include whether a detection object exists in the area to be cleaned. In another possible implementation manner, in the case that the detection object exists in the area to be cleaned, the detection object information may further include state information of the detection object, and the state information may include the number of the detection objects and/or the postures of the detection objects.
The embodiment of the application provides a sweeping robot, based on received millimeter wave echo signals, determines an implementation mode of detection object information in a to-be-swept area:
the millimeter wave radar can emit electromagnetic waves in a millimeter wave frequency range within a preset range, then the millimeter wave radar can collect echo signals, analog-to-digital conversion is carried out on the collected echo signals, and then DSP (digital signal Processing) is carried out on the converted signals to obtain point cloud data.
By analyzing and calculating the point cloud data, the sweeping robot can determine whether a detection object exists in the area to be swept or not. Further, when the detection object exists in the area to be cleaned, the sweeping robot can also determine the state information of the detection object by analyzing and calculating the point cloud data. The process of determining whether a detection object exists in the area to be cleaned and the state information of the detection object according to the point cloud data belongs to the prior art, and is not repeated in the application.
And 103, judging whether the area to be cleaned meets a preset cleaning condition or not according to the detection object information in the area to be cleaned.
In implementation, the user can set different preset cleaning conditions for different cleaning areas in the cleaning route, and the sweeping robot can judge whether the area to be cleaned meets the preset cleaning conditions corresponding to the area to be cleaned according to the detection object information in the area to be cleaned.
Or, for a plurality of cleaning areas in the cleaning route, the cleaning robot can judge whether each area to be cleaned meets the same preset cleaning condition.
In the embodiment of the application, according to different types of detection object information, the floor sweeping robot determines whether the specific processing procedure of the area to be cleaned, which meets the preset cleaning condition, is different, and the detailed description of the specific processing procedure will be described later.
If the area to be cleaned meets the preset cleaning condition, the sweeping robot can clean the area to be cleaned.
And step 104, if the area to be cleaned does not meet the preset cleaning condition, determining the next area to be cleaned according to the cleaning route stored in advance.
In implementation, if the area to be cleaned does not satisfy the preset cleaning condition, the sweeping robot may determine the next area to be cleaned according to the cleaning route. Then, the sweeping robot can continuously judge whether the next area to be swept meets the preset sweeping condition or not until all the sweeping areas in the sweeping route are traversed.
In the embodiment of the application, the sweeping robot can transmit millimeter waves to the area to be swept, and based on the received echo signals of the millimeter waves, the information of the detection object in the area to be swept is determined; and then, judging whether the area to be cleaned meets a preset cleaning condition or not according to the detection object information in the area to be cleaned. And if the area to be cleaned does not meet the preset cleaning condition, determining the next area to be cleaned according to the cleaning route stored in advance.
Because when the detection object information in the area to be cleaned does not meet the preset cleaning condition, the area to be cleaned is not cleaned, active adjustment of a cleaning route can be realized, and intelligent obstacle avoidance can be realized.
Optionally, an embodiment of the present application further provides an implementation manner in which the sweeping robot determines whether a detection object exists in an area to be cleaned based on a received millimeter wave echo signal, as shown in fig. 2, a specific processing procedure includes:
In implementation, the sweeping robot may analyze the received echo signal of the millimeter wave to obtain a wavelength range of the echo signal. Wherein, the echo signal to the millimeter wave of receiving is analyzed, obtains the process of echo signal's wavelength range and belongs to prior art, and this application is no longer repeated.
In the implementation, the sweeping robot may determine whether the wavelength range includes the preset wavelength, and if the wavelength range includes the preset wavelength, the sweeping robot may perform step 203; if the wavelength range does not include the preset wavelength, the sweeping robot may perform step 204.
And 204, determining that no detection object exists in the area to be cleaned, and obtaining the detection object information in the area to be cleaned.
In the embodiment of the application, the sweeping robot can acquire the wavelength range of the received millimeter wave echo signal, judge whether the wavelength range contains the preset wavelength, determine that a detection object exists in the area to be cleaned when the wavelength range contains the preset wavelength, and determine that the detection object does not exist in the area to be cleaned when the wavelength range does not contain the preset wavelength. Because the millimeter wave has the characteristic of reflecting the wave with a specific wavelength when contacting a human body or an animal, whether the detection object exists in the area to be cleaned is determined based on judging whether the wavelength range of the echo signal of the millimeter wave contains the preset wavelength, and the detection object information in the area to be cleaned can be quickly obtained. Furthermore, the sweeping robot can rapidly determine whether to sweep the area to be swept.
Optionally, when the detection object information includes whether there is a detection object in the to-be-cleaned area, the floor sweeping robot determines whether the to-be-cleaned area satisfies a preset cleaning condition according to the detection object information in the to-be-cleaned area, and the processing procedure may include:
and if the detection object exists in the area to be cleaned, judging that the area to be cleaned does not meet the preset cleaning condition. And if the detection object does not exist in the area to be cleaned, judging that the area to be cleaned meets the preset cleaning condition.
In the embodiment of the application, under the condition that the detection object information includes whether the detection object exists in the area to be cleaned, the sweeping robot can judge that the area to be cleaned does not meet the preset cleaning condition when the detection object exists in the area to be cleaned, and judge that the area to be cleaned meets the preset cleaning condition when the detection object does not exist in the area to be cleaned. When the detection object exists in the area to be cleaned, the floor sweeping robot judges that the area to be cleaned does not meet the preset cleaning condition, and further does not clean the area to be cleaned, so that the cleaning route can be actively adjusted, and intelligent obstacle avoidance can be realized. Moreover, the disturbance brought to the detection object when the area to be cleaned with the detection object is cleaned can be avoided, so that the user experience can be improved.
Optionally, under the condition that there is the detection object in the area to be cleaned, the robot of sweeping the floor can further acquire the state information of the detection object, and then based on the state information of the detection object, judge whether the area to be cleaned satisfies the preset cleaning condition, and the specific processing procedure includes:
step one, if a detection object exists in the area to be cleaned, state information of the detection object is obtained.
In implementation, the sweeping robot may analyze the point cloud data of the area to be swept to obtain the state information of the detection object, and the specific processing process may refer to the processing process in step 102, which is not described herein again.
And step two, judging whether the state information of the detection object meets a preset state condition.
In implementation, the sweeping robot can determine whether the state information of the detection object meets a preset state condition. If the state information of the detection object meets the preset state condition, the sweeping robot can judge that the area to be swept does not meet the preset sweeping condition; if the state information of the detection object does not meet the preset state condition, the sweeping robot can judge that the area to be swept meets the preset sweeping condition.
Optionally, when the status information includes a number, the preset status condition may be; the number of the detection objects reaches a preset threshold value.
Therefore, if the number of the detection objects reaches the preset threshold value, the state information of the detection objects meets the preset state condition, and the sweeping robot can judge that the area to be cleaned does not meet the preset cleaning condition. If the number of the detection objects does not reach the preset threshold value, the state information of the detection objects does not meet the preset state condition, and the sweeping robot can judge that the area to be cleaned meets the preset cleaning condition.
When the state information includes a gesture, the preset state condition may be: the posture of the detection object is a preset disturbance prevention posture, wherein the preset disturbance prevention posture comprises any one of sitting, standing and lying.
Therefore, if the posture of the detection object is the preset disturbance prevention posture, the state information of the detection object meets the preset state condition, and the sweeping robot can judge that the area to be cleaned does not meet the preset cleaning condition. If the posture of the detection object is not the preset disturbance prevention posture, the state information of the detection object does not meet the preset state condition, and the sweeping robot can judge that the area to be cleaned meets the preset cleaning condition.
When the state information includes the number and the posture, the preset state condition may be that the number of the detection objects reaches a preset threshold, and/or that the posture of the detection object is a preset disturbance prevention posture.
For example, the area to be cleaned is a bedroom, and the detection object information acquired by the sweeping robot is as follows: there are 1 detection object in the area to be cleaned, and the posture of the detection object is lying. The sweeping robot can judge that the detection object information in the area to be cleaned meets the preset state condition, and the area to be cleaned does not meet the preset cleaning condition. The sweeping robot may then not sweep the bedroom.
In the embodiment of the application, under the condition that the detection object exists in the area to be cleaned, the sweeping robot can judge that the area to be cleaned does not meet the preset cleaning condition and does not clean the area to be cleaned when the state information such as the number and/or the posture of the detection object meets the preset state condition. Therefore, the sweeping robot can adjust the sweeping route according to the state information of the detection object, and intelligent obstacle avoidance can be achieved. Furthermore, the user experience can be improved.
An example of a method for adjusting a cleaning route of a cleaning robot is also provided in the embodiments of the present application, and as shown in fig. 3, the method specifically includes the following steps:
And step 302, acquiring the wavelength range of the received millimeter wave echo signal.
If the wavelength range includes the preset wavelength, it is determined that the detection object exists in the area to be cleaned, and step 304 is executed.
If the wavelength range does not contain the preset wavelength, it is determined that the detection object does not exist in the area to be cleaned, and step 307 is executed.
And step 304, acquiring the state information of the detection object.
And 305, judging whether the state information of the detection object meets a preset state condition.
If the state information of the detection object satisfies the preset state condition, step 306 is executed.
If the status information of the detection object does not satisfy the preset status condition, step 307 is executed.
And step 306, judging that the area to be cleaned does not meet the preset cleaning condition, and determining the next area to be cleaned according to the cleaning route stored in advance.
And 307, judging that the area to be cleaned meets the preset cleaning condition, and cleaning the area to be cleaned.
