For example, when there is debris on a clean floor, the sweeping robot can better sweep the floor by performing a single sweeping mode. However, in different cleaning environments, the cleaning performance of the cleaning robot with only a single cleaning mode is obviously insufficient, and the cleaning is often incomplete or impossible. For example, when cleaning rough ground or carpet, the sweeping robot has a single mode, so that the cleaning effect is poor or the cleaning cannot be performed due to insufficient suction of the fan.

In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a sweeping robot provided in an embodiment of the present application. The sweeping robot comprises a transmitting pipe 13, a receiving pipe 14, a processor 10, a memory 11, a fan 17, a steering unit 15 and a sweeping unit 16. Wherein, the transmitting pipe 13, the receiving pipe 14, the storage 11, the fan 17, the steering unit 15 and the cleaning unit 16 are all connected with the processor 10. A computer program in the memory and executable on the processor, the processor implementing the cleaning method provided herein when executing the computer program. The fan is under the control of treater, and then changes the suction of fan to the rubbish that will treat the region that cleans is inhaled into rubbish recovery storehouse. The steering unit comprises a steering driving motor and a steering wheel, the steering motor is used for driving and controlling the steering wheel to rotate under the control of the processor, and the advancing steering angle or the stopping motion of the sweeping robot is adjusted. The cleaning unit comprises a cleaning driving motor and a cleaning wheel, the cleaning driving motor drives the cleaning wheel to rotate under the control of the processor, and the garbage in the area to be cleaned is cleaned. The emission tube emits a detection light beam to an area to be cleaned under the control of the processor, the environment type of the area to be cleaned is detected, and the receiving tube receives reflected light of the detection light beam reflected by the area to be cleaned. In particular, the receiving pipe may include one, or in order to improve the accuracy of detection, the receiving pipe may include a plurality of pipes so as to receive reflected light of the probe beam reflected by the region to be cleaned from a plurality of angles.

Referring to fig. 2, fig. 2 is a schematic flow chart of a cleaning method according to an embodiment of the present application. The main execution body of the cleaning method in this embodiment is a cleaning robot. As shown in fig. 2, the cleaning method provided by the present application may include:

s101: and emitting a detection light beam to the area to be cleaned.

And after the sweeping robot acquires the cleaning task, responding and controlling the transmitting tube to transmit parallel detection beams to the area to be cleaned according to the analysis result of the cleaning task. The probe beam may be an infrared probe beam.

S102: and determining the environment type of the area to be cleaned according to the light sensing voltage value of the reflected light of the detection light beam.

And after receiving the reflected light of the detection light beam, the receiving tube of the sweeping robot converts the illumination intensity value of the reflected light into a light sensation voltage value, and transmits the light sensation voltage value to a processor, and the processor determines the environment type of the area to be cleaned according to the light sensation voltage value.

For example, after the sweeping robot controls the transmitting tube to transmit the probe light to the area to be swept, the receiving tube detects that the light sensation voltage value corresponding to the light intensity of the reflected light is 1V. The sweeping robot compares the obtained 1V light sensation voltage value with the critical light sensation voltage values corresponding to the preset environment types, for example, the preset light sensation voltage value corresponding to the step is 1.5V, and the environment type of the area to be swept is determined to be the step by the sweeping robot because 1V is less than 1.5V.

S103: and cleaning the area to be cleaned according to a cleaning mode corresponding to the environment type.

After determining the environment type of the area to be cleaned, the sweeping robot acquires data information of a corresponding sweeping mode according to the environment type, controls the operation of the sweeping robot according to the data information, and cleans the area to be cleaned. The operation data information of the steering wheel, the fan, the cleaning wheel or the mopping wheel in the cleaning mode corresponding to each environment type is different, for example, the operation data information of the steering wheel, the fan, the cleaning wheel or the mopping wheel in the cleaning mode corresponding to the step is different from the operation data information of the steering wheel, the fan, the cleaning wheel or the mopping wheel in the cleaning mode corresponding to the smooth floor.

For example, currently, the steering angle of the steering wheel of the sweeping robot is 0 ° and the sweeping robot travels forwards, the suction force of the fan is 1000Pa, and the rotation speed of the sweeping wheel is 2000 revolutions. In addition, at the current moment, the sweeping robot determines that the environment type of the area to be swept in the advancing direction is a step according to the light sensation voltage value corresponding to the reflected light of the detection light beam, and then the sweeping robot stops the advancing operation of the steering wheel, stops the air draft operation of the fan and stops the rotation of the sweeping wheel according to the sweeping mode corresponding to the step.

Or at the current moment, the sweeping robot determines that the environment type of the area to be swept in the traveling direction is a rough floor according to the light sensation voltage value corresponding to the reflected light of the detection light beam, the processor keeps the steering angle of the steering wheel to be 0 degree and travels forwards according to the sweeping mode corresponding to the rough floor, the air draft suction force of the fan is adjusted to be 1500Pa, and the rotating speed of the sweeping wheel is 3000 turns.

In one example, referring to fig. 3, in a possible scenario, in order to more accurately determine the environment type of the area to be cleaned according to the reflected light, the sweeping robot is provided with a first receiving tube and a second receiving tube, and the first receiving tube is located between the transmitting tube and the second receiving tube. The first receiving tube and the second receiving tube are used for receiving the sub-beams of the reflected light, so that the environment type of the area to be cleaned is determined according to the light sensing voltage values of the sub-beams.

Therefore, when the sweeping robot is provided with a first receiving tube and a second receiving tube for receiving the reflected light of the probe beam, the reflected light comprises a first sub-beam and a second sub-beam, and the receiving position of the first sub-beam is located in the middle of the emitting position of the probe beam and the receiving position of the second sub-beam; the light sensing voltage value comprises a first light sensing voltage value of the first sub-beam and a second light sensing voltage value of the second sub-beam.

Further, the receiving position of a first receiving pipe for receiving the first sub-beam on the sweeping robot is located at a position corresponding to the spot formed when the probe beam reaches the area to be swept.

Furthermore, the receiving position of a second receiving tube for receiving the second sub-beam on the sweeping robot is located in the angle direction of the probe beam after being reflected by the mirror surface of the area to be swept.

In a possible implementation manner, the reflected light only includes the second sub-beam, and a receiving position of the second sub-beam on the sweeping robot is located in an angular direction of the probe beam after being specularly reflected by the area to be swept.

The light sensing voltage value only comprises a second light sensing voltage value of the second sub-beam. And the sweeping robot determines the environment type of the area to be swept according to the second light sensing voltage value of the second sub-beam.

In an embodiment, the environment type of the area to be cleaned is determined according to the first light sensing voltage value, the second light sensing voltage value, a first preset value and a second preset value, wherein the first preset value is smaller than the second preset value.

The first preset value is a critical light sensation voltage value corresponding to reflected light reflected by the step when the corresponding environment type is the step, and the second preset value is a critical light sensation voltage value corresponding to reflected light reflected by the black tile when the corresponding environment type is the black tile.

Specifically, if the first light sensing voltage value and the second light sensing voltage value are both greater than the first preset value, the second light sensing voltage value is greater than the second preset value, and the second light sensing voltage value is greater than the first light sensing voltage value of a preset multiple, it is determined that the environment type of the area to be cleaned is a smooth floor. The smooth floor is a floor with a surface roughness higher than a preset surface roughness level, for example, a floor with a surface roughness higher than a preset surface roughness level of 8, such as a wood floor with a surface roughness level of 9.

In addition, if the first light sensing voltage value and the second light sensing voltage value are both greater than the first preset value, and the second light sensing voltage value is smaller than the first light sensing voltage value of preset times, the environment type of the area to be cleaned is determined to be a rough-surface floor. The rough-surface floor is a floor with a surface roughness lower than a preset surface roughness level, such as a floor with a surface roughness lower than a preset surface roughness level of 8, such as a wood floor with a surface roughness level of 7.

In addition, if the second light sensing voltage value is smaller than the first preset value, the environment type of the area to be cleaned is determined to be a step.

Illustratively, the first preset value is a critical photosensitive voltage value corresponding to the probe beam irradiated on the step, and is 1.2V; the second preset value is a critical light sensing voltage value corresponding to the black tile irradiated by the probe beam, and is 1.5V. After the emitting tube on the sweeping robot emits the detection light beam to the area to be cleaned, the first receiving tube and the second receiving tube respectively receive the first sub-light beam and the second sub-light beam, and a first light sensation voltage value corresponding to the first sub-light beam is 1.6V, and a second light sensation voltage value corresponding to the second sub-light beam is 3.3V. It can be seen that the first photo sensing voltage and the second photo sensing voltage are both greater than the first predetermined value of 1.2V, and the second photo sensing voltage is greater than the second predetermined value of 1.5V. Meanwhile, the second light sensation voltage value is larger than the first light sensation voltage value which is multiplied by 2 times in the preset time, so that the environment type of the area to be cleaned in the traveling direction of the sweeping robot is determined to be a smooth floor.

Or, for example, the first photosensitive voltage value corresponding to the first sub-beam is 2V, and the second photosensitive voltage value corresponding to the second sub-beam is 3.0V. As can be seen, the first light sensing voltage value and the second light sensing voltage value are both greater than a first preset value of 1.2V, and the second light sensing voltage value is greater than a second preset value of 1.5V, but the second light sensing voltage value is still less than the first light sensing voltage value multiplied by 2 times, so that it is determined that the environment type of the area to be cleaned in the traveling direction of the sweeping robot is a rough floor.

Or, if the first receiving tube and the second receiving tube respectively receive the first sub-beam and the second sub-beam, and the first light sensing voltage value corresponding to the first sub-beam is 1.6V, and the second light sensing voltage value corresponding to the second sub-beam is 1.0V, but the second light sensing voltage value is smaller than the first preset value of 1.2V, it is determined that the environment type of the area to be cleaned in the traveling direction of the sweeping robot is a step.

In one embodiment, the environment type of the area to be cleaned is determined according to a third light sensing voltage value corresponding to the emitted light.

Specifically, if the first light sensation voltage value, the second light sensation voltage value and the third light sensation voltage value are all larger than the first preset value, the second light sensation voltage value is larger than the second preset value, and the second light sensation voltage value is larger than the first light sensation voltage value of a preset multiple, it is determined that the environment type of the area to be cleaned is a smooth floor.

And if the first light sensation voltage value, the second light sensation voltage value and the third light sensation voltage value are all larger than the first preset value, and the second light sensation voltage value is smaller than the first light sensation voltage value of preset multiple, determining that the environment type of the area to be cleaned is a rough-surface floor.

Illustratively, the first preset value is 1.2V, and the second preset value is 1.5V. The first light sensing voltage value corresponding to the first sub-beam is 1.6V, the second light sensing voltage value corresponding to the second sub-beam is 3.3V, and the third light sensing voltage value corresponding to the emitted light is 4V. It can be seen that the first photo sensing voltage, the second photo sensing voltage and the third photo sensing voltage are all greater than the first predetermined value of 1.2V, and the second photo sensing voltage is greater than the second predetermined value of 1.5V. Meanwhile, the second light sensation voltage value is larger than the first light sensation voltage value which is multiplied by 2 times in the preset time, so that the environment type of the area to be cleaned in the traveling direction of the sweeping robot is determined to be a smooth floor.

Or, for example, the first light sensing voltage value corresponding to the first sub-beam is 2V, the second light sensing voltage value corresponding to the second sub-beam is 3V, and the third light sensing voltage value corresponding to the emitted light is 4V. As can be seen, the first light sensing voltage value, the second light sensing voltage value and the third light sensing voltage value are all greater than a first preset value of 1.2V, the second light sensing voltage value is greater than a second preset value of 1.5V, and the environment type of the area to be cleaned in the traveling direction of the sweeping robot is determined to be a rough floor because the second light sensing voltage value is still less than 2 times the first light sensing voltage value.

In an example, the area to be cleaned may also be a white tile, and the critical light sensing voltage value corresponding to the white tile irradiated by the probe beam is greater than the critical light sensing voltage value corresponding to the black tile irradiated by the probe beam, that is, the third predetermined value > the second predetermined value > the first predetermined value.

Specifically, if the first light sensing voltage value and the second light sensing voltage value are both greater than the first preset value, the second light sensing voltage value is smaller than the third preset value and greater than the second preset value, and the second light sensing voltage value is greater than the first light sensing voltage value of a preset multiple, it is determined that the environment type of the area to be cleaned is a smooth floor.

In a possible implementation manner, if the first light sensing voltage value and the second light sensing voltage value are both greater than the first preset value, the second light sensing voltage value is greater than the third preset value, and the second light sensing voltage value is greater than the first light sensing voltage value of a preset multiple, it is determined that the environment type of the area to be cleaned is a smooth floor.

Further, the area to be cleaned may also be a carpet, and the critical light sensing voltage value corresponding to the probe beam irradiated on the carpet is smaller than the critical light sensing voltage value corresponding to the probe beam irradiated on the black tile, but larger than the critical light sensing voltage value corresponding to the probe beam irradiated on the step, i.e. the third preset value > the second preset value > the fourth preset value > the first preset value.

In a possible implementation manner, if the first light sensing voltage value and the second light sensing voltage value are both greater than the first preset value, the second light sensing voltage value is smaller than the second preset value and greater than the first preset value, and the second light sensing voltage value is greater than the first light sensing voltage value of a preset multiple, it is determined that the environment type of the area to be cleaned is a carpet.

In one example, in a possible scenario, during the traveling of the sweeper robot, if only the probe beam is directed to the area to be swept, and the environment type of the area to be swept is determined according to the light-sensitive voltage value of the reflected light of the probe beam, the error is relatively large. For example, the probe beam just irradiates on the rough part in the area to be cleaned, and other parts of the area to be cleaned are all smooth floors, if the area to be cleaned is cleaned by switching to a cleaning mode corresponding to the rough floor, if the rough part has only one light spot size, the power consumption and the cleaning effect of the cleaning robot are not proportional.

For example, the area ratio of the smooth floor to the rough floor in the area to be cleaned is 16: 1, if the sweeping robot is immediately switched to a sweeping mode corresponding to a rough floor to sweep the area to be swept, and the sweeping power of the sweeping mode is maximum, the power consumption of the sweeping robot is greatly increased, so that the environment type of the area to be swept needs to be determined for multiple times to select the optimal sweeping mode.

Therefore, the sweeping robot controls the transmitting tube to transmit the detection light beams to the area to be cleaned on the basis of different transmitting angles for N times continuously, and determines the environment type of the area to be cleaned according to the light sensing voltage values of the reflected light of the detection light beams for N times continuously. After the transmitting tube transmits the detection light beam based on one angle, the preset angle is automatically adjusted, and the detection light beam of the next angle is transmitted after a preset time period.

And if the determined environment types are the same according to the light sensation voltage values of the reflected light of the detection light beams which are continuously emitted to the area to be cleaned based on different emission angles for N times, cleaning the area to be cleaned according to a cleaning mode corresponding to the environment types, wherein N is not less than 2, and N is an integer.

Illustratively, the emission tube of the sweeping robot emits the probe beams to the to-be-swept area for 3 consecutive times based on different emission angles of 0 °, 3 ° and 6 °, and the environment types of the to-be-swept area determined according to the light sensation voltage values of the reflected light of the probe beams for 3 consecutive times are all smooth floors, and the to-be-swept area is swept according to the sweeping mode corresponding to the smooth floor.

In one example, the environment type of the area to be cleaned is determined N times according to light sensing voltage values of reflected light of probe light beams emitted to the area to be cleaned on the basis of different emission angles for N consecutive times, if the proportion occupied by the times of the same environment type reaches or exceeds a preset proportion, the environment type of the area to be cleaned is determined to be the environment type of which the proportion occupied by the times reaches or exceeds the preset proportion, and the area to be cleaned is cleaned according to a cleaning mode corresponding to the environment type.

For example, the environment type of the area to be cleaned is determined 10 times according to the light sensing voltage values of the reflected light of the probe light beams emitted to the area to be cleaned continuously 10 times based on different emission angles, wherein the number of times of confirming that the environment type of the area to be cleaned is a rough floor is 8 times, the number of times of confirming that the area to be cleaned is a smooth floor is 2 times, and a preset ratio is 7/10, and since the ratio 8/10 occupied by the same environment type number of times exceeds the preset ratio, the environment type of the area to be cleaned is confirmed to be a rough floor, and the area to be cleaned is cleaned according to a cleaning mode corresponding to the rough floor.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
