Embodiments of present disclosure will be given in part in the following descriptions, become apparent in part from the following descriptions, or be learned from the practice of the embodiments of the present disclosure.
Embodiments of the present disclosure will become apparent and more readily appreciated from the following descriptions made with reference to the drawings, in which:
Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the drawings. The same or similar elements are denoted by same reference numerals in different drawings unless indicated otherwise. The embodiments described herein with reference to drawings are explanatory, and used to generally understand the present disclosure. The embodiments shall not be construed to limit the present disclosure.
Method and apparatus for acquiring water consumption of a robot vacuum cleaner, an electronic device and a non-transitory computer readable storage medium according to embodiments of the present disclosure are described below with reference to the drawings.
In block 101, the robot vacuum cleaner is controlled to acquire an image of ground to be cleaned, so as to acquire the image of the ground to be cleaned.
In order to realize the image acquiring function for the robot vacuum cleaner, a corresponding image acquiring device should be set on the robot vacuum cleaner. When the robot vacuum cleaner starts working, the image acquiring device is activated to collect images of ground. In one embodiment, the image acquiring device may be disposed under a body of the robot vacuum cleaner to collect the images of ground under the robot vacuum cleaner. In one embodiment, the image acquiring device may be disposed on a head of the robot vacuum cleaner to collect image information of ground in front of the robot vacuum cleaner in its forward direction, which is about to be cleaned.
In block 102, the robot vacuum cleaner is controlled to detect a humidity of the ground to be cleaned, so as to acquire humidity information of the ground to be cleaned.
In order to realize the humidity information collecting function for the robot vacuum cleaner, a corresponding humidity collecting device should be set on the robot vacuum cleaner. In one embodiment, the humidity collecting device should be disposed under the body of the robot vacuum cleaner. In order to ensure the accuracy of the humidity of the ground collected by the humidity collecting device, the humidity collecting device should be as close as possible to the ground. For a robot vacuum cleaner with a lower chassis, the humidity collecting device can be disposed inside the body, and the humidity information is collected through a through-hole at the bottom of the body. In this case, a relative small distance between the humidity collecting device and the ground can also be satisfied. For a robot vacuum cleaner with a higher chassis, the humidity collecting device is required to be a projection on the chassis of the robot vacuum cleaner.
In an actual application, the ground may be uneven. If the humidity collecting device is directly disposed on the chassis, the humidity collecting device has a great possibility to touch the ground during working, resulting in damage to the humidity collecting device, and thus the collection accuracy is affected. The humidity collecting device may even be stuck in somewhere, and thus the robot vacuum cleaner is hanging there and cannot move forward. In order to avoid above situations, in some embodiments of the present disclosure, the humidity collecting device may be disposed on or near a driving wheel at the bottom of the robot vacuum cleaner, where it is close to the ground, but will not touch the ground, thus ensuring the collection of humidity signals.
In block 103, a target water consumption of the robot vacuum cleaner is acquired according to the image of the ground and the humidity information.
In one embodiment, the image of the ground and the humidity information are input into a first trained machine learning model for learning, a recommending probability is acquired for every recommending water consumption corresponding to the ground to be cleaned, and the recommending water consumption with the highest recommending probability is selected as the target water consumption.
During the training of the first machine learning model, a plurality of recommending water consumptions is trained. After the image of the ground and the humidity information are input into the first trained machine learning model, the first machine learning model learns a recommending probability for each recommending water consumption. If a recommending probability for a recommending water consumption is closer to 1, it indicates that the robot vacuum cleaner will cause less damage to the ground with such a recommending water consumption, that is, the recommending water consumption is more suitable to the cleaning requirements of the ground. Otherwise, if a recommending probability for a recommending water consumption is closer to 0, it indicates that the robot vacuum cleaner will cause more damage to the ground with such a recommending water consumption, that is, the recommending water consumption is less suitable to the cleaning requirements of the ground. Moreover, for the recommending water consumption with a recommending probability of 0, the humidity of the robot vacuum cleaner with such a water consumption may cause a certain degree of damage to the ground. Therefore, after acquiring all the recommending probabilities for all the recommending water consumptions, the recommending water consumption with the highest recommending probability is selected as the target water consumption.
It should be noted that, in the embodiments of the present disclosure, the image of the ground and the humidity information are collected by the robot vacuum cleaner, and the processes of analyzing the collected data and acquiring the water consumption for the cleaning process may be performed by a cloud server, or may be performed by the robot vacuum cleaner locally. When these processes are executed locally, the first machine learning model that has been trained is pre-stored in the robot vacuum cleaner, and the collected image of the ground and the humidity information can be input into the first machine learning model to acquire the target water consumption.
When these processes are executed by the cloud server, the collected image of the ground and the humidity information are sent from the robot vacuum cleaner to the cloud server through a wireless network. The cloud server can acquire the image of the ground and the humidity information, and then combine the first machine learning model in the cloud server to acquire the corresponding target water consumption.
In general, in order to reduce the energy consumption and cost of the robot vacuum cleaner, the cloud server is often used to perform the process of acquiring the target water consumption. However, in practice, when the wireless network signal between the robot vacuum cleaner and the cloud server is unstable or the robot vacuum cleaner is not in the coverage of the wireless network, the robot vacuum cleaner cannot transmit the collected ground image and humidity information through the wireless network to the cloud server. In this case, the robot vacuum cleaner can choose to analyze the data locally and acquire the corresponding target water consumption.
In block 104, the robot vacuum cleaner is controlled to clean the ground to be cleaned according to the target water consumption.
Further, after the corresponding target water consumption is acquired, if the water consumption is acquired locally by the robot vacuum cleaner, it can be directly applied to the robot vacuum cleaner to clean the ground to be cleaned according to the target water consumption. If the target water is acquired by the cloud server, it can be sent from the cloud server back to the robot vacuum cleaner through the wireless network. The robot vacuum cleaner receives the target water consumption and cleans the ground to be cleaned accordingly.
With the method for acquiring water consumption of the robot vacuum cleaner provided in embodiments of the present disclosure, a current situation of a target to be cleaned may be detected by intelligent means, and an optimal water quantity parameter can be recommended according to the current situation, so as to realize the control of the water consumption adapted to the target to be cleaned and achieve an optimal water discharge effect, thus improving intelligence level and cleaning efficiency of the robot vacuum cleaner.
In block 201, the image of the ground is identified, ground type information of the ground to be cleaned is determined, and a first water consumption that matches the ground type information is acquired.
In actual practice, the robot vacuum cleaner may face various ground conditions. For example, most of the home floor is made of ceramic tiles. The water consumption for cleaning this kind of ground is in a large range, and the ground will not be damaged by excessive water consumption. At the same time, for some families, the ground is made of wood. This kind of ground requires a less water consumption for the robot vacuum cleaner during cleaning, otherwise it will easily cause softening, bulging and deformation of the ground. When the home ground is covered by a carpet, the water consumption of the robot vacuum cleaner should be 0, that is, the robot vacuum cleaner can only activate the sweeping function and cannot activate the mopping function at this time. In addition to the above examples, there are some other restrictions on the water output of the robot vacuum cleaner, and thus the ground type of the current cleaning ground should be determined by the robot vacuum cleaner before the water consumption is matched.
As a possible implementation manner, for example, the target water consumption is acquired by the cloud server in this embodiment. Firstly, the image of the ground collected by the image acquiring device is uploaded to the cloud server, and the cloud server responds to the robot vacuum cleaner and inputs the transmitted image of the ground into a trained ground type identifying model for learning, and acquires information of a specific ground type through analysis. Then, the first target water consumption that is matched with the learned ground type information is acquired by querying a list of a relationship between ground type information and water consumption stored in the cloud server according to the learned ground type information.
In block 202, a plurality of humidity ranges are acquired according to the ground type information, a target humidity range to which the humidity information belongs is determined, a calibration coefficient for calibrating the first water consumption is acquired according to the target humidity range, the first water consumption is calibrated with the calibration coefficient, and the target water consumption is acquired.
Further, the cloud server further stores a list of a relationship between ground type and humidity range of such the ground, and a plurality of possible humidity ranges of the ground may be acquired according to the ground type. While the above image of the ground is uploaded to the cloud server, the humidity information is also sent to the cloud server. The cloud server determines that the humidity information of the current ground is within a certain humidity range acquired as above, and the target range corresponds to the calibration coefficient for calibrating the water consumption. The first target water consumption acquired according to the ground type is calibrated with the calibration coefficient, and thus the target water consumption is acquired.
In one embodiment, a plurality of humidity ranges may be allowable for the same ground type, and the humidity ranges are continuous in humidity units (for example, water vapor pressure). Normally, the ground will not be damaged in these humidity ranges, and thus these humidity ranges can be recognized as safe humidity range of the ground. With respect to these humidity ranges, when humidity data collected from the ground is close to an upper limit of these humidity ranges, the humidity of the ground is high, and is more likely to exceed the safe humidity range and cause damage to the ground. At this time, a large calibration coefficient is required for calibrating the water output for the target, i.e., increasing restrictions on the water output, so as to reduce the water output, thus preventing the ground from being damaged by the excessive water. According to the same principle, when humidity data collected from the ground is close to a lower limit of these humidity ranges (it is found through analysis of actual situations that the ground may be damaged when the humidity of the ground is very low, for example, a concrete floor cracks when the humidity is too low), a relative low humidity is selected for calibrating the water output for the target, i.e., decreasing restrictions on the water output, where a large water consumption is used to clean the ground more completely. Moreover, the adjacent humidity can adopt a same calibration coefficient as long as the humidity does not exceed the above humidity range after the calibration, that is, the above-mentioned safe humidity range is divided into different continuous regions according to different calibration coefficients, and each region has the same calibration coefficient, which is beneficial to the storage and the query in the cloud server.
With the method for acquiring water consumption of the robot vacuum cleaner provided in embodiments of the present disclosure, by uploading the ground type and the humidity information to the cloud server for machine learning to check the ground type and the humidity information, where an optimal water quantity parameter can be recommended, so as to realize the control of the water consumption adapted to the target to be cleaned and achieve an optimal water discharge effect, thus improving intelligence level and cleaning efficiency of the robot vacuum cleaner.
In an embodiment of the present disclosure, after the target water consumption is acquired as described above, the target water consumption may be further optimized by combining information of geographic location, weather condition, seasonal characteristics and humidity. In one embodiment, in rainy days, the air humidity is high and the water on the ground is difficult to evaporate, where it is more likely to cause the accumulation of water, so as to exceed a safe range and cause damage to the ground when compared with other conditions. Therefore, the target water consumption should be reduced in rainy days. While, in some hot areas, the ambient temperature is high, the air humidity is high, the water on the ground is also difficult to evaporate, and thus the target water consumption should also be reduced in these areas.
In block 301, a target area, where the ground to be cleaned is positioned, and weather information of the target area are acquired.
In an embodiment of the present disclosure, the robot vacuum cleaner may be connected to a weather forecasting server through network, and then receive current weather information from the server through the network. Moreover, a positioning device is disposed on the robot vacuum cleaner, and positioning information is acquired by the positioning device. Further, according to the positioning information, the target area (geographical location) where the ground to be cleaned is positioned can be determined.
In block 302, the target water consumption is calibrated by utilizing the target area and the weather information.
As a possible implementation manner, after the target area and the weather information are acquired, the image of the ground, the humidity information, the target area and the weather information are input into a second trained machine learning model for learning, a recommending probability is acquired for every recommending water consumption corresponding to the ground to be cleaned, and the recommending water consumption with the highest recommending probability is selected as the target water consumption. Since more factors affecting the water consumption, such as the geographical location and the weather condition, have been considered during the machine learning, the target water consumption may be calibrated accordingly, where the finally acquired water consumption is more suitable to the actual requirements of a current application scenario of the robot vacuum cleaner.
It should be noted that, in the embodiments of the present disclosure, the image of the ground, the humidity information, the target area and the weather information are collected by the robot vacuum cleaner, and the processes of analyzing the collected information and acquiring the water consumption during the cleaning process may be performed by the cloud server or locally by the sweeping robot. For the process performed by the cloud server or may be performed by the robot vacuum cleaner locally. These processes performed by the cloud server or the local terminal may refer to the description of related contents in the foregoing embodiments, which are not described in detail here again.
As another possible implementation manner, the cloud server stores a relationship list showing different weather information and corresponding calibration coefficients thereof. At the same time, calibration coefficients corresponding to different target areas are also stored. After the two kinds of calibration coefficients are searched and determined, the target water consumption, which is acquired by analyzing the image of the ground and the humidity information, is calibrated with the calibration coefficient for the weather information, so as to acquire a first target water consumption. Then, the first target water consumption is calibrated with the calibration coefficient for the target area, so as to acquire a second target water consumption. The second target water consumption as acquired finally is used as a final target water consumption of the robot vacuum cleaner. The cloud server transmits the selected target water consumption to the robot vacuum cleaner, and controls the robot vacuum cleaner to clean the ground according to the target water consumption.
In this embodiment of the present disclosure, by creating analyzing and learning the target area and the weather information of the robot vacuum cleaner, the target water consumption is further calibrated, thus further improving the accuracy of selecting the water consumption for the robot vacuum cleaner, and efficiently avoiding the possible damage caused by wrongly selected water consumption.
