For detection operations environment, path navigation.The various sensors (not indicated in figure) of positioning.When clean robot enters one
When relatively spacious working region, the present invention provides the cleaning modes for being directed to the region.Skill of the invention is described in detail below
Art scheme.
It is illustrated in figure 3 a kind of schematic diagram of the cleaning mode of clean robot provided by the invention, clean robot 100
In the cleaning mode successively the following steps are included:
A. clean robot enters a working region, carries out Coarse Acquisition to working environment and confirms that it has entered one
The step of depletion region;
B. for clean robot the step of the depletion region carries out all standing cleaning, it is clear that clean robot carries out all standing
When clean, path coverage density is greater than path coverage density of the clean robot in Coarse Acquisition;
C. clean robot meets the step of cleaning mode described in systemic presupposition condition backed off after random.

The cleaning mode.It can blindly be cleaned in zone of ignorance to avoid clean robot in this way, repeat cleaning to increase clearly
The clean time and reduce cleaning efficiency.
Depletion region of the present invention, which refers to, meets fixed condition set by cleaning robot system (will be described hereinafter)
Region.Depletion region i.e. described here refers to opposite depletion region, and clean robot carries out complete in the depletion region
The barrier encountered when covering cleaning is less, and clean robot has higher cleaning efficiency and cleaning effect.
All standing cleaning of the present invention refers to that path coverage density is greater than the clean robot in Coarse Acquisition
When path coverage density, and its cleaning path has specific sports rule, and cleaning path can be substantially over entire sky
Spacious region.
It should be noted that if clean robot is in a step, when to the Coarse Acquisition of working environment, working environment is simultaneously
It is unsatisfactory for the condition of a depletion region, then, b step is not carried out in clean robot, only confirmed a spacious job
After environment, clean robot can just execute b step, if clean robot can not confirm a depletion region, cleaner always
Device people executes other cleaning modes.Essence of the invention is that a depletion region is found in working region, thus in the area
Domain executes all standing cleaning, improves cleaning efficiency, avoids blindly being cleaned in depletion region, repeats cleaning and reduce cleaning
Efficiency.
It is illustrated in figure 4 clean robot and determines that it has entered the judgment method schematic diagram an of depletion region.In a
In step, the clean robot 100 randomly chooses a kind of motion path when carrying out Coarse Acquisition to working environment, and
The number or the distance between collision interval or each collision of collision are recorded in movement;When within the predetermined time (such as 1
In minute), the collision frequency of clean robot is less than systemic presupposition value (such as 6 beats/min) or in scheduled collision frequency (example
Such as 6 times) in, there is the collision interval of scheduled collision frequency (such as 5 times) to be greater than systemic presupposition value (in 6 collisions at least
There are 5 time intervals to be greater than 5 seconds) or in predetermined collision frequency (such as 6 times), there is scheduled collision frequency (such as 5 times)
The distance between collision be greater than systemic presupposition value (the collision spacing of at least 5 times collisions are greater than 2.5 meters in 6 collisions), then
Clean robot confirms that it has entered a depletion region.
Fig. 5 to Fig. 9 shows clean robot, and entering a working region, (in the present embodiment, working region is boundary 9
The region surrounded) after, several different walking paths when Coarse Acquisition are carried out to working environment, arrow direction indicates in each figure
The direction of motion of clean robot 100.
Specifically, in Fig. 5, the clean robot is walked with zigzag;Clean robot 100 by the lower right corner to the left
Walking encounters the oblique right side walking of one angle of rotation behind boundary 9, rotates an angle again (so that with setting out after encountering boundary 9
When direction it is roughly the same) backward left lateral walks, stops until encountering boundary 9;In Fig. 6, clean robot 100 is with Z as shown in Figure 5
Origin is returned to after font walking;In Fig. 7, clean robot random motion, when encountering boundary 9(wall or barrier), then change
Become the direction of motion far from barrier;In Fig. 8, clean robot 100 is using pentalpha as motion path;In Fig. 9, clean robot
Using another pentalpha as motion path.In above diagram, when within the predetermined time, when within the predetermined time,
The collision frequency of clean robot has the collision of scheduled collision frequency less than systemic presupposition value or in scheduled collision frequency
Time interval is greater than systemic presupposition value or in predetermined collision frequency, has the distance between the collision of scheduled collision frequency to be greater than
Systemic presupposition value, then clean robot confirms that it has entered a depletion region.
Specifically, in a step, clean robot 100 to working environment carry out Coarse Acquisition while also to ground into
Row cleaning, i.e., in Fig. 5 into motion path shown in Fig. 9, clean robot 100 simultaneously cleans ground.A kind of implementation
In example, in b step, when clean robot 100 carries out all standing cleaning, cleaning power is greater than the clean robot thick
Cleaning power when slightly cleaning.
In a step, when clean robot 100 is to working environment progress Coarse Acquisition (as shown in Figures 5 to 9
Path), at least two key point K1 and K2 are recorded in the search coverage, including starting point K1 and one farthest away from
The key point K2 of the starting point K1;In the b step, clean robot 100 at least to cover when all standing cleaning
The key point K1 and K2;For clean robot in the step c, systemic presupposition condition is that confirmation clean robot 100 carries out
After all standing has covered the key point K1 and K2 when cleaning, the cleaning mode is exited.
Figure 10 to Figure 15 shows several different cleaning paths of the clean robot when carrying out all standing cleaning, each to scheme
In arrow indicate clean robot moving direction.In the present embodiment, as shown in Fig. 5 to Figure 15, the work that is surrounded due to boundary 9
Make without barrier among region, therefore the working region that boundary 9 surrounds is defined as a depletion region by clean robot.
Specifically, Tu10Zhong, clean robot carry out all standing cleaning to bend vee path V to the depletion region.Cleaning
Robot 100 walks to the right from the off, and arrival 9 rear steering of boundary moves down a distance rear steering and walks to the left, arrives
A distance is moved down again after up to boundary 9 to walk to the right again, so repeats down, walks back and forth, advance downwardly, until covering
Entire depletion region.Since the walking path of clean robot is superimposed similar to multiple " bow " fonts, it is defined as " bow
Vee path V ".
In Figure 11, clean robot carries out all standing cleaning to the depletion region with zigzag path.Clean robot
100 walk to the right by starting point, and pivot stud reaches pivot stud court behind boundary 9 towards the oblique walking in left side after reaching boundary 9
Right side walking, so repeats down, walks back and forth, advance downwardly, until covering entire depletion region.Due to clean robot
Walking path is superimposed similar to multiple " Z " fonts, therefore is defined as " zigzag path ".It should be noted that shown in Figure 11
Zigzag path it is bigger than the density of zigzag shown in fig. 5, the cleaning assemblies of clean robot 100 can be covered substantially entirely
Depletion region.
In Figure 12, clean robot carries out all standing cleaning to the depletion region with E vee path V.Clean robot
Then 100 first run to the right from starting point to boundary 9, then backtracking move down a distance to starting point, then move right
It moves to boundary 9, then backtracking.That is, left and right is cleaned back and forth, a distance, then left and right is promoted to clean back and forth still further below, still further below
It promotes, so repeats, walk back and forth, advance downwardly, until covering entire depletion region.Since its motion path is similar to multiple
The superposition of " E " font, therefore it is defined as " E vee path V ".
In Figure 13 and Figure 14, clean robot carries out all standing cleaning to the depletion region with spirality path, wherein
Figure 13 show round spiral path, the side of showing Figure 14 spiral path.
In Figure 15, clean robot 100 carries out all standing cleaning to the depletion region with latticed path, is equivalent to cross
Superposition to " bow font " path and longitudinal " bow vee path V ".Due to the path be similar to it is latticed, which is determined
Justice is " latticed path ".
Clean robot is when carrying out all standing cleaning, other than Figure 10 to path shown in figure 15, can also there are many
Overlay path, the present invention are not necessarily to exhaustion herein, as long as path coverage density is greater than the clean robot in Coarse Acquisition work
Make path coverage density when environment, and its cleaning path has a specific sports rule, cleaning path can be substantially over
The present invention can be achieved in the path of entire depletion region.
In other embodiments, as shown in figure 16, in the working region that boundary 9 surrounds, be dispersed with three barriers 91,
92,93;Clean robot 100 selects random walk to carry out Coarse Acquisition to working environment in working region, when scheduled
In, such as in 1 minute, 6 collisions are had occurred in clean robot 100, less than the threshold value (example of cleaning robot system setting
Such as 8 beats/min), then clean robot 100 confirms that it is entered a depletion region (Figure 17 dotted line area defined), and
Selection " bow font " path carries out all standing cleaning to the depletion region, as shown in figure 18.Clean robot 100 is to workspace
When domain carries out Coarse Acquisition, three key points K1, K2 and K3 are had recorded, wherein K1 is that clean robot carries out slightly working environment
Starting point when slightly detecting;K2 is the point farthest away from K1;K3 is point when colliding in working region with obstacle 93.Clean machine
People 100 is when carrying out all standing cleaning to depletion region, after clean robot covers three key point K1, K2 and K3, i.e.,
The cleaning mode can be exited.
In other embodiments, in the step c, systemic presupposition condition is clean robot when all standing is cleaned,
The collision frequency of clean robot and obstacle or the time interval collided every time are recorded during exercise or per between collision twice
Distance;When within the predetermined time (such as in 1 minute), the collision frequency of clean robot is greater than systemic presupposition value (such as 6
Beat/min) or in scheduled collision frequency (such as 6 times), there is the collision interval of scheduled collision frequency (such as 5 times)
Less than systemic presupposition value (at least 5 times time intervals are greater than 5 seconds in 6 collisions) or in predetermined collision frequency (such as 6 times)
It is interior, there is the distance between collision of scheduled collision frequency (such as 5 times) to be less than systemic presupposition value (at least 5 times in 6 collisions
The collision spacing of collision is greater than 2.5 meters), then clean robot exits the cleaning mode.
