The ground treatment method provided by the embodiment of the invention will be described in detail below with reference to the drawings and specific embodiments.
As shown in fig. 1, a flowchart of a ground treatment method according to an embodiment of the present disclosure is provided, and the method includes the following steps:
step S101: acquiring target information of a target user identified in a target area, wherein the target information comprises height information and movement information of the target user, and the target area is an action area of an air outlet function of electrical equipment;
step S102: and determining the ground state of the target area based on the target information and a preset ground state judging rule.
The preset ground state judging rule is trained based on a plurality of pieces of history information acquired by a history user when the history user walks on a dry ground and/or a wet ground, and each piece of history information comprises height information and movement information of the corresponding history user.
The method provided by the embodiment of the specification can be applied to electrical equipment with an air outlet function, such as an air conditioner, a fan and the like, can also be applied to a server in communication connection with the electrical equipment, and can also be applied to a system consisting of the electrical equipment and the server, and is not limited herein.
In step S101, when the electrical equipment starts the air outlet function, the electrical equipment is taken as an example of an air conditioner, and the action area of the air outlet function of the air conditioner may be a range where a distance from the air conditioner is smaller than a preset distance, and the preset distance may be determined according to an actual power of the air conditioner, for example, the preset distance is 2m, 3m, and the like.
In order to ensure that the electric equipment can perform air drying treatment on the ground of the target area, the target area can be the whole action area corresponding to the air outlet function, or can be a partial area in the action area, and the air drying treatment is not limited herein. In order to judge the ground state of the target area, when the existence of the target user in the target area is recognized, the height information and the movement information of the target user are acquired.
In the embodiment of the present specification, the ground state is determined by the movement characteristics of the user on the wet ground as well as the dry ground, and thus, the target user may be any user who moves in the target area. To identify the target user, sensors may be mounted on the electrical device, including but not limited to cameras, millimeter wave radars, lidars, and the like. Of course, the sensor may be provided at a position other than the electric apparatus as long as the sensor can capture the user information on the target area, and the sensor transmits the user information to the electric apparatus after collecting the user information.
For convenience of explanation, the radar is set on the electrical equipment as an example to explain the identification of the target user and the acquisition process of the target information:
in a specific implementation process, the identification of the target user can be realized through the following steps: acquiring point cloud data of the radar, wherein the point cloud data is obtained by detecting the target area; and taking the region with the point cloud area meeting the preset area range as the human body region corresponding to the target user based on the point cloud data.
Specifically, the radar can be arranged at any position of the electrical equipment according to actual needs, the detection range of the radar can cover a target area, the radar continuously transmits electromagnetic waves to the environment through the transmitting antenna, meanwhile, echo data are received through the receiving antenna, and point cloud data comprising the target area can be obtained based on the transmitting data and the echo data.
After the point cloud data is obtained, preprocessing such as denoising can be performed on the point cloud data, and a human body region in the target region can be identified based on the preprocessed point cloud data. Due to the possible presence of beds, sofas, etc. in the target area, the human bodyIn the embodiment of the present disclosure, a preset area range of the human body region may be set according to the area characteristics of the human body region, for example, the preset area range is 0.4-0.6m 2 、0.45-0.65m 2 Etc. The region satisfying the preset area range is taken as the human body region corresponding to the target user, and the human body can be identified by integrating the region outline and the like besides judging the region area, and the method is not limited herein.
Further, the height information of the target user can be determined based on the human body area corresponding to the target user. For example, the highest point of the human body region and the lowest point of the human body region are determined, and the distance between the highest point and the lowest point is calculated as the height information of the target user.
In addition, the movement information of the target user can be determined by: acquiring the transmitting frequency and the receiving frequency of the radar; determining a speed profile of the target user moving toward the radar based on a frequency difference between the transmit frequency and the receive frequency; and determining movement information of the target user based on the speed curve.
Specifically, the radar continuously transmits electromagnetic waves through the transmitting antenna, and simultaneously, the receiving antenna continuously receives echo data, and the frequency difference between the transmitting frequency and the receiving frequency is calculated by acquiring the transmitting frequency and the receiving frequency of the radar, and based on the Doppler effect, the moving speed of the target user to the radar can be obtained according to the speed calculation formula. Since the speed is continuously calculated, a speed profile of the movement of the target user to the radar can be generated, and based on the speed profile, movement information of the target user can be determined. Of course, the speed profile may also be determined by other means, for example, obtaining the transmission time of the transmitted electromagnetic wave of the transmitting antenna and the reception time of the echo received by the receiving antenna, calculating the time difference between the transmission time and the reception time, calculating the distance between the target user and the radar based on the time difference, and since the radar continuously transmits the electromagnetic wave and receives the echo data, the distance change between the target and the radar can be obtained, and the speed profile can be obtained based on the distance change and the corresponding duration. In the present embodiment, the speed profile may be obtained only by the present embodiment, and the process of obtaining the speed profile is not described here.
In the embodiment of the present specification, the movement information may include a frequency domain feature of the velocity profile and/or a time domain feature of the velocity profile. Next, a description will be given of a frequency domain feature and a time domain feature of the velocity profile, respectively.
The frequency domain characteristics of the velocity profile can be obtained by: performing Fourier transform on the speed curve to obtain a mobile frequency spectrum of the target user; and determining a first frequency corresponding to the pause of the target user and/or a second frequency corresponding to the speed peak value of the target user from the moving frequency spectrum as moving information of the target user.
Specifically, the velocity profile is fourier-transformed to obtain a corresponding moving spectrum, wherein the moving spectrum includes frequencies and amplitudes of a plurality of signals constituting the velocity profile. Because the user walks on the wet ground at a slower speed and with a greater number of pauses, frequencies corresponding to pauses and frequencies corresponding to speed peaks can be screened from the frequency spectrum of the movement. In the implementation process, frequencies with the amplitude of 0 in the mobile spectrum can be filtered out, and the average value of all the frequencies with the amplitude of 0 is calculated as the first frequency. The frequency with the largest amplitude in the moving spectrum is set as the second frequency corresponding to the velocity peak.
The time domain characteristics of the velocity profile can be obtained by: and determining the pause time and the moving speed of the target user in the moving process from the speed curve, and taking the pause time and the moving speed as the moving information of the target user.
Specifically, since the speed profile is a profile in which the speed changes with time, the situation when the target user walks on the ground in the target area can be represented, and therefore, the duration with the speed of 0 can be determined from the speed profile, and as the pause duration, since the situation with the speed of 0 may occur multiple times, the duration with the speed of 0 multiple times can be averaged, and the average value can be taken as the pause duration. Meanwhile, the speed average value may be calculated as the moving speed based on the speed profile, or the maximum speed may be read out from the speed profile as the moving speed, which is not limited herein.
In step S102, after obtaining the target information of the target user, the target information may be processed based on a preset ground state judgment rule, so as to obtain the ground state of the target area.
It should be noted that the preset ground state judgment rule may include various forms. For example, the preset ground state is a trained ground state determining model, and each piece of history information of the history user when walking on the dry ground and/or the wet ground can be used as one piece of sample data when the model is trained, for example, when the user A walks on the dry target area ground, the height information and the movement information of the user A are recorded as one piece of sample data; when the user B walks on the wet target area floor, height information and movement information of the user B are recorded as one piece of sample data. When the ground state determining model is trained, the height information and the movement information of the user are used as the input of the model, the ground state is used as the output of the model, and the trained ground state determining model is obtained through multiple iterations. Thus, after the target information of the target user is obtained, the target information can be input into the trained ground state determination model, and the ground state can be output.
The preset ground state judgment rule can also be one or more sets of preset corresponding relations among height information, movement information and ground states.
In the embodiment of the present disclosure, it is considered that the walking speeds of the people with different heights are also different, for example, in the same environment, such as a living room environment of a family, the walking speed is faster for the people with higher height due to the larger stride, so that in the preset ground state judgment rules, the corresponding ground state rules can be set for each height interval.
In a specific implementation process, the preset ground state judgment rule can be realized by the following steps: dividing the plurality of pieces of history information into N groups of information sets corresponding to N groups of preset height intervals based on the height information of the history user in each piece of history information and N groups of preset height intervals, wherein N is an integer larger than 1; and determining ground dry movement reference information and/or ground wet movement reference information corresponding to the set of preset height intervals as ground state judgment rules corresponding to the set of preset height intervals according to the movement information in the set of information sets.
Specifically, the N groups of preset height intervals can be set according to actual needs, for example, heights are divided into four groups, and in the first preset height interval, the range of the height h is h < 1.3m; in a second preset height interval, the height h is in a range of 1.3 m-1.5 m; in a third preset height interval, the height h is in a range of 1.5 m-1.7 m; in a fourth preset height interval, the height h is in a range of more than or equal to 1.7m.
Because each piece of history information contains height information, movement information and ground state of the corresponding user, each piece of history information can be divided into corresponding preset height intervals based on the height information in each piece of history information, and one or more pieces of history information are corresponding to each group of preset height intervals, so that N groups of information sets are obtained.
Further, for each group of preset height intervals, the corresponding historical information can be grouped according to the ground state. For example, taking the third preset height section as an example, 20 pieces of history information are corresponding, wherein the ground state with 12 pieces of history information is a dry state, and the ground state with 8 pieces of history information is a wet state, so 12 pieces of history information in the dry state can be used as a group for generating ground dry movement reference information, and/or 8 pieces of history information in the wet state can be used as a group for generating ground wet movement reference information.
It should be noted that, for each group of preset height intervals, when determining the corresponding ground drying movement reference information, the historical information collected during ground drying can be learned to obtain the ground drying movement reference information. Taking the third preset height as an example, corresponding to 12 pieces of history information acquired during ground drying, learning the characteristics of the 12 pieces of history information to obtain a set of reference movement information, where the reference movement information includes, but is not limited to, a pause frequency interval, a speed peak frequency interval, a pause duration interval, and a movement speed interval. In one embodiment, each item of data contained in the movement information in the 12 pieces of history information may be subjected to average calculation and variance calculation, and a section of each item of data may be determined according to the result, as the floor drying reference movement information.
Similarly, for each set of preset height intervals, the manner of determining the corresponding ground wet movement reference information is the same as the manner of determining the ground dry movement reference information, which is not described herein.
Further, determining the ground state of the target area based on the preset ground state judgment rule may include the following steps: determining a target height interval in which the height information of the target user is located from the N groups of preset height intervals; and comparing the ground dry movement reference information and/or the ground wet movement reference information corresponding to the target height interval with the movement information of the target user, and determining the ground state of the target area according to a comparison result.
Specifically, after the target information is obtained, comparing the height information in the target information with N groups of preset height sections to determine the target height section where the height information of the target user is located. If the target height interval corresponds to the ground drying movement reference information, including a pause frequency interval, a speed peak frequency interval, a pause duration interval and a movement speed interval during ground drying, the movement information of the target user, including the first frequency of pause, the second frequency of the speed peak, the pause duration and the movement speed, are respectively compared with the corresponding intervals, if the target height interval is not in the interval corresponding to the movement reference information, the ground is determined to be moist, and if the target height interval is not in the interval corresponding to the movement reference information, the ground is determined to be dry.
Similarly, if the target height section corresponds to the ground moisture reference information, the movement information of the target user can be compared with each section with the ground moisture respectively, if the target height section is not in the corresponding section, the ground is determined to be dry, and if the target height section is in the corresponding section, the ground is determined to be wet.
In this embodiment of the present disclosure, the preset ground state determination rule may include a plurality of sets of ground state determination rules for a plurality of sets of preset height sections, and may also set the ground state determination rule only for the reference height section. The reference height interval can be set according to actual needs, for example, the reference height interval is 1.65 m-1.75 m, or 1.6 m-1.8 m, etc.
The construction of the preset ground state judgment rule aiming at the reference height interval can be realized by the following steps: m pieces of history information of which the height information meets a reference height interval are screened out from the plurality of pieces of history information, wherein M is a positive integer; and determining ground dry movement reference information and/or ground wet movement reference information corresponding to the reference height interval based on the movement information in the M pieces of historical information, and taking the ground dry movement reference information and/or the ground wet movement reference information as the preset ground state judgment rule.
Specifically, since each piece of history information includes height information, movement information and ground state of the corresponding user, M pieces of history information with the height information in the reference height section can be screened out based on the height information in each piece of history information, and M is a positive integer. In addition, the M pieces of historical information can be grouped according to the ground state, the historical information in the ground dry state is a group, the historical information in the ground wet state is a group, further, the ground dry movement reference information is obtained according to the learning of the historical information in the ground dry state, and/or the ground wet movement reference information is obtained according to the learning of the historical information in the ground wet state.
The ground dry movement reference information and/or the ground wet movement reference information may be determined by referring to the above description, and will not be described again.
Correspondingly, when the preset ground state judgment rule only comprises the ground state judgment rule corresponding to the reference height interval, the ground state of the target area can be determined by the following steps: if the height information of the target user is not in the reference height interval, weighting the ground dry moving reference information and/or the ground wet moving reference information corresponding to the reference height interval based on the height information of the target user; and comparing the ground dry moving reference information and/or the ground wet moving reference information after the weighting processing with the moving information of the target user, and determining the ground state of the target area according to the comparison result.
In particular, because there is a correlation between height and movement information, for example, on dry floors, users with higher heights move faster, with shorter dwell periods, while users with lower heights move slower, with longer dwell periods than users with higher heights. Therefore, when the height of the target user is not in the reference height section, it is inaccurate to determine the ground state by using the preset ground state judgment rule matched with the reference height section. Therefore, the dry movement reference information and/or the wet movement reference information of the ground in the preset ground state judgment rule can be weighted according to the height of the target user.
For example, if the preset ground state judgment rule corresponds to the drying movement reference information, and the movement reference information includes a movement speed and a pause time, then when the height of the target user is less than the lower limit of the reference height interval, the movement speed and the pause time in the drying movement reference information are respectively weighted, so as to reduce the movement speed and increase the pause time, and the weighted movement speed and pause time are matched with the height information of the target user.
Of course, when the height information of the target user is within the reference height interval, each item of reference data in the dry moving reference information and/or the ground wet moving reference may be weighted, so that the weighted reference data is more suitable for the height information of the target user. The weight to be weighted may be set according to the actual situation, for example, by analyzing the difference between the movement information of each height section to determine the weight between each height section and the reference height section, which is not limited herein.
Further, after step S103, if the ground state of the target area is a wet state, the air-out function of the electrical equipment is started to air-dry the ground of the target area.
Specifically, if the ground state of the target area is a wet state, in order to ensure the safety of the user walking in the target area, the air outlet function of the electrical equipment can be controlled to be started, and the air outlet quantity, the air outlet mode and the like corresponding to the air outlet function can be set according to actual needs. Taking electrical equipment as an air conditioner for example, after detecting that the ground state is a wet state, the air conditioner can be controlled to operate in a dehumidifying air outlet mode, and the ground is uniformly swept by 1 grade.
In summary, in the embodiment of the present disclosure, the ground state of the target area may be determined by detecting the target information of the target user in the target area based on the preset ground state determination rule, and when the ground state is a wet state, the electrical apparatus is controlled to start the air-out mode to perform the air-drying treatment on the wet ground. The whole process does not need user intervention, so that the intelligent degree of ground state judgment is improved, and the user experience is improved.
