The following are detailed descriptions.

[0092] Embodiment 1

[0093] See also Figure 1 , Figure 1 1 is a flow chart of a pet toilet detection method applied to a cat litter box disclosed in an embodiment of the present invention. Figure 1The pet toilet detection method applied to a cat litter box described above can be applied to a pet toilet detection device, which may include a detection device, a detection terminal, a detection system, and a server, wherein the server may be a local server or a cloud server, which is not limited in the embodiments of the present invention. Figure 1 As shown, the pet toilet detection method applied to a cat litter box may include the following operations:

[0094] 101. Based on the sensor group, detect the detection area corresponding to the cat litter box to obtain the pet detection result corresponding to the cat litter box.

[0095] In an embodiment of the present invention, the sensor group includes a plurality of sensors; optionally, each sensor in the sensor group can be set at different positions on the cat litter box and / or set on a smart device associated with the cat litter box (such as: set on a monitoring device associated with the cat litter box), which is not limited in the embodiment of the present invention. Wherein, the detection area corresponding to the cat litter box at least includes the area inside the basin corresponding to the cat litter box; optionally, the above-mentioned detection area can also include a surrounding area of ​​any shape with the cat litter box as the center and a preset radius value as the radius, which is not limited in the embodiment of the present invention; exemplarily, the above-mentioned preset radius value can be the sum of the size parameters of the cat litter box (such as: one of the radius, diameter, length, and width) and the preset distance value (such as: 10 cm), which is not limited in the embodiment of the present invention; exemplarily, the arbitrary shape can be one of a sector, a semicircle, and a circle, or other shapes, which is not limited in the embodiment of the present invention. Wherein, the above-mentioned pet detection result is used to indicate whether there is a target pet entering the detection area corresponding to the cat litter box.

[0096] 102. When the pet detection result is used to indicate that a target pet has entered the detection area, the length of time the target pet stays in the detection area is detected.

[0097] In the embodiment of the present invention, the above-mentioned stay duration is the duration corresponding to a time segment starting at the time when the target pet enters the detection area and ending at the time when the target pet leaves the detection area.

[0098] 103. Determine the pet toileting detection result corresponding to the cat litter box based on the length of stay.

[0099] In an embodiment of the present invention, the pet toilet detection result at least includes a pet toilet sign; wherein the pet toilet sign can be an effective toilet sign or an invalid toilet sign. Optionally, the pet toilet detection result can also include a toilet situation analysis result corresponding to the target pet determined based on the pet detection result, which is not limited in the embodiment of the present invention; further optionally, the toilet situation analysis result can include a combination of one or more of an effective toilet analysis result, a defecation duration analysis result, a defecation frequency analysis result, a defecation volume analysis result, and a defecation state analysis result, which is not limited in the embodiment of the present invention; wherein, optionally, the effective toilet analysis result can include the frequency ratio of effective toileting after the pet enters the detection area corresponding to the cat litter box and / or the behavior analysis of invalid toileting after the pet enters the detection area corresponding to the cat litter box (such as: analysis of other behaviors such as playing / resting after the pet enters the cat litter box instead of defecating). Wherein, the target pet can be any pet (such as a cat) living in the environment of the cat litter box, which is not limited in the embodiment of the present invention.

[0100] In the embodiment of the present invention, optionally, when the pet toilet mark is a valid toilet mark, it can trigger the cat litter box to perform a cleaning operation, which is not limited in the embodiment of the present invention.

[0101] It can be seen that the method described in the embodiment of the present invention can detect the detection area corresponding to the cat litter box through the sensor. If a target pet is detected to enter the detection area, the length of time the target pet stays in the detection area is detected, and then the pet toilet detection result corresponding to the cat litter box is determined based on the length of time. Comprehensive detection of whether a pet has entered the cat litter box can be achieved through multiple sensors, thereby achieving intelligent detection of the pet's toileting in the cat litter box on the basis of improving the accuracy of pet detection, thereby improving the detection efficiency and accuracy of the pet's toileting, which is beneficial to improving the timeliness and accuracy of cleaning the cat litter box, and is beneficial to improving the user experience of the cat litter box.

[0102] In an optional embodiment, the sensor group may include a radar sensor, a laser sensor, an infrared sensor and a camera unit.

[0103] Among them, the radar sensor can be used to detect moving objects, the laser sensor can be used to detect objects that can reflect lasers, and the infrared sensor can be used to detect objects that emit heat; that is, the sensing detection objects corresponding to the radar sensor may include moving objects, the sensing detection objects corresponding to the laser sensor may include laser reflecting objects, and the sensing detection objects corresponding to the infrared sensor may include infrared radiating objects, which are not limited in the embodiments of the present invention. Among them, the target detection object can be an object detected by the target detection technology in the image recognition technology / video recognition technology; further, the object represented by the target detection object can include any pet living in the environment where the cat litter box is located.

[0104] Exemplarily, the imaging unit may be a camera, or other components or devices capable of collecting image data and / or video data, which is not limited in the embodiments of the present invention.

[0105] It can be seen that this optional embodiment can detect the cat litter box from multiple angles through multiple types of sensors, which is beneficial to improving the comprehensiveness of detection of pets entering the detection area.

[0106] In this optional embodiment, optionally, based on the sensor group, detecting the detection area corresponding to the cat litter box and obtaining the pet detection result corresponding to the cat litter box may include the following operations:

[0107] Based on the radar sensor, detecting whether there is a moving object entering a first detection area of ​​the radar sensor with respect to the cat litter box, and obtaining a first detection result;

[0108] Based on the laser sensor, detecting whether there is a laser reflecting object entering a second detection area of ​​the laser sensor with respect to the cat litter box, and obtaining a second detection result;

[0109] Based on the infrared sensor, detecting whether there is an infrared radiation object entering a third detection area of ​​the infrared sensor with respect to the cat litter box, and obtaining a third detection result;

[0110] Based on the camera unit, detecting whether a target detection object enters a fourth detection area of ​​the camera unit with respect to the cat litter box, and obtaining a fourth detection result; the target detection object includes a video recognition object and / or an image recognition object;

[0111] A pet detection result corresponding to the cat litter box is determined according to the first detection result, the second detection result, the third detection result and the fourth detection result.

[0112] Among them, optionally, the first detection area, the second detection area, the third detection area and the fourth detection area can be the same detection range, and the first detection area, the second detection area, the third detection area and the fourth detection area may not be the same detection range but there are overlapping detection ranges among the three, which is not limited in the embodiment of the present invention.

[0113] It can be seen that this optional embodiment can detect whether there is a moving object through a radar sensor, detect whether there is a laser reflecting object through a laser sensor, and detect whether there is an infrared radiation object entering the corresponding detection area through an infrared sensor, and obtain the first detection result, the second detection result, the third detection result and the fourth detection result respectively, and then determine the pet detection result corresponding to the cat litter box based on the above-mentioned sensor detection results, which can improve the detection flexibility and comprehensiveness of pets entering the detection area, thereby helping to improve the accuracy of the determination of pet detection results, and further helping to improve the accuracy of subsequent detection of pet toileting situations.

[0114] In this optional embodiment, optionally, determining the pet detection result corresponding to the cat litter box according to the first detection result, the second detection result, the third detection result and the fourth detection result may include the following operations:

[0115] Determine whether the sensing detection results corresponding to each sensor are all used to indicate that the sensing detection object corresponding to the sensor has entered the sensing detection area corresponding to the sensor; all the sensing detection results include the first detection result, the second detection result, the third detection result and the fourth detection result;

[0116] When it is determined that the sensing detection results corresponding to each sensor are used to indicate that the sensing detection object corresponding to the sensor has entered the sensing detection area corresponding to the sensor, the pet detection result corresponding to the cat litter box is determined as the target pet has entered the detection area corresponding to the cat litter box;

[0117] When it is determined that the sensor detection result corresponding to any sensor is used to indicate that the sensor detection object corresponding to the sensor does not enter the sensor detection area corresponding to the sensor, the pet detection result corresponding to the cat litter box is determined as no target pet enters the detection area corresponding to the cat litter box.

[0118] For example, if it is not a pet but a toy car that enters the detection area, the first detection result and the second detection result may both indicate that there is a corresponding sensor detection object entering the corresponding sensor detection area, while the third detection result may indicate that no infrared radiation object enters the third detection area, and the fourth detection result may indicate the image of a toy car detected in the fourth detection area. At this time, it can be determined that there is no target pet entering the detection area corresponding to the cat litter box, which is not limited to this embodiment of the present invention.

[0119] It can be seen that this optional embodiment can also determine that a target pet has entered the detection area corresponding to the cat litter box only when it is determined that the detection results corresponding to all sensors are used to indicate that a sensor detection object has entered the sensor detection area. If one of the detection results indicates that no sensor detection object has entered the sensor detection area, it is determined that no target pet has entered the detection area, which can reduce the possibility of judging other targets as pets, thereby further improving the accuracy of judging whether a pet has entered the detection area, so as to improve the accuracy of the pet detection results.

[0120] In this optional embodiment, optionally, after determining that the sensing detection results corresponding to each sensor are used to indicate that there is a sensing detection object corresponding to the sensor entering the sensing detection area corresponding to the sensor, the method may further include the following operations:

[0121] Determine object parameters corresponding to the object to be confirmed according to the first detection result, the second detection result, the third detection result and the fourth detection result; wherein the object parameters may include first body shape information of the object to be confirmed and / or first body temperature information of the object to be confirmed;

[0122] Obtaining pet parameters corresponding to each pet living in the environment where the cat litter box is located; wherein the pet parameters may include the second body shape information of the pet and / or the second body temperature information of the pet;

[0123] Determine whether the above object parameters match one of the pet parameters;

[0124] When it is determined that the object parameter matches one of the pet parameters, an operation is triggered to determine the pet detection result corresponding to the cat litter box as the presence of the target pet entering the detection area corresponding to the cat litter box;

[0125] When it is determined that the object parameters do not match any pet parameters, an operation is triggered to determine the pet detection result corresponding to the cat litter box as an absence of the target pet entering the detection area corresponding to the cat litter box.

[0126] For example, if it is not a cat but a baby that enters the detection area, and the body shape of a baby is usually different from that of a cat and the body temperature of a cat is higher than that of a baby, then when it is determined that the first body shape information is different from the second body shape information of any pet and the first body shape information is lower than the second body temperature information of any pet, it can be determined that there is no target pet entering the above-mentioned detection area.

[0127] It can be seen that this optional embodiment can further judge whether the object parameters of the target monitoring object match the pet parameters corresponding to one of the pets living in the environment where the cat litter box is located on the basis of judging that the detection results corresponding to all sensors are used to indicate that a sensor detection object has entered the sensor detection area. If the judgment result is yes, it can be determined that a target pet has entered the detection area, which can reduce the possibility of judging other non-pet creatures such as babies as pets, thereby helping to further improve the accuracy of judging whether a pet has entered the detection area, so as to further improve the accuracy of the pet detection results.

[0128] In another optional embodiment, when the pet detection result is used to indicate that a target pet has entered the detection area, the method may further include the following operations:

[0129] Determine whether the cat litter box is in a working state; the working state includes one of a cat litter cleaning state, a feces cleaning state, a sand collection bin cleaning state, and a deodorizing cleaning state;

[0130] When it is determined that the cat litter box is in a working state, the cat litter box is controlled to stop executing a target operation corresponding to the working state.

[0131] The litter collecting bin may be used to collect cat litter and / or pet excrement, which is not limited in the embodiment of the present invention.

[0132] For example, when the cat litter box is in a feces cleaning state, the cat litter box may be controlled to stop performing the feces cleaning operation, which is not limited in the embodiment of the present invention.

[0133] It can be seen that this optional embodiment can control the cat litter box to suspend the execution of corresponding operations when a pet enters the detection area if it is determined that the cat litter box is in working state, so as to reduce the possibility of the operation of the cat litter box harming the pet when the pet enters the detection area, thereby improving the operating safety of the cat litter box.

[0134] In this optional embodiment, optionally, after determining the pet toilet detection result corresponding to the cat litter box according to the stay time, the method may further include the following operations:

[0135] Determine whether the target pet has left the detection area;

[0136] When it is determined that the target pet has left the detection area, the operation of step 101 is performed again;

[0137] When it is determined that the target pet has not left the detection area, the operation of controlling the cat litter box to stop executing the target operation corresponding to the working state continues to be executed.

[0138] It can be seen that this optional embodiment can also re-execute the detection operation corresponding to the sensor when it is determined that the target pet has left the detection area, which can be beneficial to continuously detect whether the pet has entered the detection range, so as to improve the timeliness of the determination of the pet's toilet situation; and when it is determined that the target pet has not left the detection area, the cat litter box maintains a suspended operation state, which can further improve the operating safety of the cat litter box.

Figure 2 The pet toilet detection method applied to a cat litter box described above can be applied to a pet toilet detection device, which may include a detection device, a detection terminal, a detection system, and a server, wherein the server may be a local server or a cloud server, which is not limited in the embodiments of the present invention.

[0141] 201. Based on the sensor group, detect the detection area corresponding to the cat litter box to obtain the pet detection result corresponding to the cat litter box.

[0142] In the embodiment of the present invention, the sensor group includes a plurality of sensors.

[0143] 202. When the pet detection result is used to indicate that a target pet has entered the detection area, the length of time the target pet stays in the detection area is detected.

[0144] 203. Determine whether the stay duration is greater than or equal to a preset duration.

[0145] In the embodiment of the present invention, when step 203 determines that the stay duration is greater than or equal to the preset duration, the operation of step 204 is triggered; when step 203 determines that the stay duration is less than the preset duration, the operation of step 205 is triggered.

[0146] In the embodiment of the present invention, illustratively, the preset duration may be 30 seconds, or may be a duration of other values, which is not limited in the embodiment of the present invention.

[0147] 204. Determine that the pet toilet sign corresponding to the cat litter box is a valid toilet sign.

[0148] In the embodiment of the present invention, the effective toilet sign can be used to indicate that the pet has completed defecation after entering the cat litter box.

[0149] 205. Determine that the pet toilet sign corresponding to the cat litter box is an invalid toilet sign.

[0150] In the embodiment of the present invention, the invalid toilet sign can be used to indicate that the pet did not defecate after entering the cat litter box.

[0151] In the embodiment of the present invention, for other detailed descriptions of step 201 - step 202, please refer to the detailed description of step 101 - step 102 in the first embodiment, and the embodiment of the present invention will not be repeated here.

[0152] It can be seen that the method described in the embodiment of the present invention can detect the detection area corresponding to the cat litter box through the sensor. If it is detected that a target pet enters the detection area, the target pet's stay time in the detection area is detected, and then the pet toilet detection result corresponding to the cat litter box is determined according to the stay time. It can realize comprehensive detection of whether a pet enters the cat litter box through multiple sensors, so that on the basis of improving the accuracy of pet detection, it can realize intelligent detection of the pet's toilet situation in the cat litter box, thereby improving the detection efficiency and detection accuracy of the pet's toilet situation, thereby helping to improve the timeliness and accuracy of cleaning the cat litter box, and helping to improve the user's experience of using the cat litter box. In addition, it is also possible to determine the pet toilet mark by judging whether the stay time of the pet in the cat litter box is greater than or equal to the preset time, and when the judgment result is yes, determine the pet toilet mark as a valid toilet mark, otherwise, determine the pet toilet mark corresponding to the cat litter box as an invalid toilet mark, which can further improve the efficiency and accuracy of determining whether the pet goes to the toilet in the cat litter box, which is conducive to improving the accuracy of determining the pet toilet mark, thereby helping to improve the timeliness and accuracy of cleaning the cat litter box.

[0153] In an optional embodiment, after determining that the stay duration is greater than or equal to the preset duration, the method may further include the following operations:

[0154] Determine whether there is feces corresponding to the target pet in the cat litter box;

[0155] When it is determined that there is excrement corresponding to the target pet in the cat litter box, an operation is triggered to determine that the pet toilet mark corresponding to the cat litter box is a valid toilet mark:

[0156] When it is determined that there is no excrement corresponding to the target pet in the cat litter box, an operation of determining that the pet toilet mark corresponding to the cat litter box is an invalid toilet mark is triggered.

[0157] The feces may include excrement and / or excrement.

[0158] It can be seen that this optional embodiment can further determine whether there is excrement of the target pet in the cat litter box after determining that the stay time is greater than or equal to the preset time. If the judgment result is yes, the pet toilet mark is determined to be a valid toilet mark, otherwise, the pet toilet mark is determined to be an invalid toilet mark, which can reduce the possibility of judging the pet's stay in the cat litter box (such as resting or playing) as toilet behavior, thereby further improving the accuracy of determining whether the pet goes to the toilet in the cat litter box, and further improving the accuracy of determining the pet toilet mark.

[0159] In this optional embodiment, optionally, determining whether there is excrement corresponding to the target pet in the cat litter box may include the following operations:

[0160] Obtaining pet information corresponding to the target pet, environmental information of the environment in which the cat litter box is located, and cat litter information of the cat litter placed in the cat litter box;

[0161] Analyze the expected temperature change result corresponding to the area inside the cat litter box according to the pet information, environmental information and cat litter information; the expected temperature change result is the estimated temperature change result corresponding to the area inside the cat litter box after the target pet defecates;

[0162] Determine the waiting time for feces detection corresponding to the cat litter box;

[0163] After the target pet is detected to have left the detection area, the actual temperature detection result corresponding to the area inside the cat litter box is detected within a time period corresponding to the waiting time for the defecation detection;

[0164] Determining the temperature change similarity between the expected temperature change result and the actual temperature detection result;

[0165] Determine whether the temperature change similarity is greater than or equal to a preset similarity;

[0166] When it is determined that the temperature change similarity is greater than or equal to the preset similarity, it is determined that there is excrement corresponding to the target pet in the cat litter box;

[0167] When it is determined that the temperature change similarity is less than the preset similarity, it is determined that there is no excrement corresponding to the target pet in the cat litter box.

[0168] Among them, optionally, the pet information corresponding to the target pet may include target body temperature information, target body shape information and feces temperature information, which is not limited in the embodiment of the present invention; the environmental information of the environment in which the cat litter box is located may include at least one of season information, ambient temperature information, ambient humidity information and indoor and outdoor ventilation information, which is not limited in the embodiment of the present invention; the cat litter information of the cat litter placed in the cat litter box may include at least one of the type of cat litter, the amount of cat litter, and the specific heat capacity of the cat litter, which is not limited in the embodiment of the present invention.

[0169] Among them, optionally, the expected temperature change results may include the expected temperature change results at positions corresponding to multiple preset positions in the basin area; the actual temperature detection results may include the actual temperature detection results at positions corresponding to the above-mentioned multiple preset positions detected at multiple times, which is not limited in the embodiments of the present invention.

[0170] Among them, optionally, analyzing the expected temperature change results corresponding to the inner area of ​​the cat litter box according to the pet information, environmental information and cat litter information can include the following operations: determining the heat dissipation speed corresponding to the cat litter according to the cat litter information; analyzing the heat dissipation influence coefficient for the cat litter in the above environment according to the environmental information; analyzing the expected temperature change results corresponding to the inner area of ​​the cat litter box according to the pet information, the heat dissipation speed and the heat dissipation influence coefficient, which is not limited to the embodiments of the present invention.

[0171] It can be seen that this optional embodiment can also analyze the expected temperature change result in the cat litter box according to the acquired pet information, environmental information and cat litter information, and then determine the waiting time for the feces detection corresponding to the cat litter box, and after detecting that the target pet leaves the detection area and within the time period corresponding to the waiting time for the feces detection, detect the actual temperature detection result in the cat litter box, and then determine the temperature change similarity between the expected temperature change result and the actual temperature detection result. When it is judged that the temperature change similarity is greater than or equal to the preset similarity, it is determined that there is feces corresponding to the target pet in the cat litter box. Otherwise, it is determined that there is no feces corresponding to the target pet in the cat litter box, which can improve the accuracy of the analysis of the temperature change of whether the pet defecates in the cat litter box. If the cat does not defecate in the cat litter box, the above-mentioned determined temperature change similarity will be lower, thereby improving the accuracy of determining whether there is feces corresponding to the target pet in the cat litter box, which is conducive to further reducing the possibility of determining the behavior of the pet staying in the cat litter box (such as resting or playing) as toilet behavior, so as to further improve the accuracy of determining whether the pet goes to the toilet in the cat litter box.

[0172] In the embodiment of the present invention, the flowchart of the pet toilet detection method for a cat litter box can be found in Figure 3 ,in, Figure 3 FIG. 1 is a flow chart of another pet toilet detection method applied to a cat litter box disclosed in an embodiment of the present invention. Figure 3 As shown, the method may include the following operations:

[0173] First, use multiple sensors to detect whether a cat has entered the litter box. Specifically, radar can be used to detect whether a moving object has entered the detection range (to achieve moving object detection), laser can be used to detect whether a cat has entered the laser scanning range (to achieve laser reflection object detection), infrared can be used to detect whether a creature has entered the detection range (to achieve heat emitting object detection), and camera recognition can be used to detect whether a cat has entered the camera range (to achieve target detection for cats through image / video recognition technology), and then the detection results of the above sensors are combined to determine whether a cat has entered the litter box. If the judgment result is no, continue to perform the detection step through multiple sensors; if the judgment result is yes, suspend the working state of the litter box, and detect whether the cat stays in the litter box for more than 30 seconds. When the cat stays for more than 30 seconds, the pet toilet mark is recorded as a valid toilet mark; then determine whether the cat has left the litter box. If the cat has left, re-execute the detection step; if the cat has not left, continue to maintain the suspended working state of the litter box, which is not limited in the embodiment of the present invention.

[0174] Embodiment 3

[0175] See also Figure 4 , Figure 4 1 is a schematic diagram of a pet toilet detection device for a cat litter box disclosed in an embodiment of the present invention. Figure 4 The pet toilet detection device applied to the cat litter box described may include one of a detection device, a detection terminal, a detection system and a server, wherein the server may be a local server or a cloud server, which is not limited in the embodiment of the present invention. Figure 4 As shown, the pet toilet detection device applied to a cat litter box may include:

[0176] The detection module 301 is used to detect the detection area corresponding to the cat litter box based on the sensor group, and obtain the pet detection result corresponding to the cat litter box; the sensor group includes multiple sensors;

[0177] The detection module 301 is also used to detect the length of time the target pet stays in the detection area when the pet detection result is used to indicate that the target pet has entered the detection area;

[0178] The determination module 302 is used to determine the pet toileting detection result corresponding to the cat litter box according to the stay time; the pet toileting detection result at least includes a pet toileting mark.

[0179] It can be seen that the device described in the embodiment of the present invention can detect the detection area corresponding to the cat litter box through sensors. If a target pet is detected to enter the detection area, the target pet's stay time in the detection area is detected, and then the pet toilet detection result corresponding to the cat litter box is determined based on the stay time. It can realize comprehensive detection of whether a pet enters the cat litter box through multiple sensors, thereby realizing intelligent detection of the pet's toileting in the cat litter box on the basis of improving the accuracy of pet detection, thereby improving the detection efficiency and accuracy of the pet's toileting, which is beneficial to improving the timeliness and accuracy of cleaning the cat litter box, and is beneficial to improving the user experience of the cat litter box.

[0180] In an optional embodiment, the sensor group may include a radar sensor, a laser sensor, an infrared sensor, and a camera unit;

[0181] The specific method in which the detection module 301 detects the detection area corresponding to the cat litter box based on the sensor group and obtains the pet detection result corresponding to the cat litter box may include:

[0182] Based on the radar sensor, detecting whether there is a moving object entering a first detection area of ​​the radar sensor with respect to the cat litter box, and obtaining a first detection result;

[0183] Based on the laser sensor, detecting whether there is a laser reflecting object entering a second detection area of ​​the laser sensor with respect to the cat litter box, and obtaining a second detection result;

[0184] Based on the infrared sensor, detecting whether there is an infrared radiation object entering a third detection area of ​​the infrared sensor with respect to the cat litter box, and obtaining a third detection result;

[0185] Based on the camera unit, detecting whether a target detection object enters a fourth detection area of ​​the camera unit with respect to the cat litter box, and obtaining a fourth detection result; the target detection object includes a video recognition object and / or an image recognition object;

[0186] A pet detection result corresponding to the cat litter box is determined according to the first detection result, the second detection result, the third detection result and the fourth detection result.

[0187] It can be seen that the device described in the implementation of this optional embodiment can detect the cat litter box from multiple angles through multiple types of sensors, which is conducive to improving the comprehensiveness of detection of pets entering the detection area; and, by respectively detecting whether a moving object is detected by a radar sensor, detecting whether a laser reflecting object is detected by a laser sensor, and detecting whether an infrared radiation object enters the corresponding detection area by an infrared sensor, a first detection result, a second detection result, a third detection result and a fourth detection result are obtained respectively, and then the pet detection result corresponding to the cat litter box is determined by combining the above-mentioned sensor detection results, which can improve the detection flexibility and comprehensiveness of pets entering the detection area, thereby facilitating improving the accuracy of determining the pet detection results, and further facilitating improving the accuracy of subsequent detection of the pet's toileting situation.

[0188] In this optional embodiment, optionally, the specific manner in which the detection module 301 determines the pet detection result corresponding to the cat litter box according to the first detection result, the second detection result, the third detection result, and the fourth detection result may include:

[0189] Determine whether the sensing detection results corresponding to each sensor are all used to indicate that the sensing detection object corresponding to the sensor has entered the sensing detection area corresponding to the sensor; all the sensing detection results include the first detection result, the second detection result, the third detection result and the fourth detection result;

[0190] When it is determined that the sensing detection results corresponding to each sensor are used to indicate that the sensing detection object corresponding to the sensor has entered the sensing detection area corresponding to the sensor, the pet detection result corresponding to the cat litter box is determined as the target pet has entered the detection area corresponding to the cat litter box;

[0191] When it is determined that the sensor detection result corresponding to any sensor is used to indicate that the sensor detection object corresponding to the sensor does not enter the sensor detection area corresponding to the sensor, the pet detection result corresponding to the cat litter box is determined as no target pet enters the detection area corresponding to the cat litter box.

[0192] It can be seen that the device described in the implementation of this optional embodiment can also determine that a target pet has entered the detection area corresponding to the cat litter box only when it is determined that the detection results corresponding to all sensors are used to indicate that a sensor detection object has entered the sensor detection area. If one of the detection results indicates that no sensor detection object has entered the sensor detection area, it is determined that no target pet has entered the detection area, which can reduce the possibility of judging other targets as pets, thereby further improving the accuracy of judging whether a pet has entered the detection area, so as to improve the accuracy of the pet detection results.

[0193] In another optional embodiment, Figure 5 As shown, the device may also include:

[0194] The first judgment module 303 is used to judge whether the cat litter box is in a working state when the pet detection result indicates that a target pet has entered the detection area; the working state includes one of a cat litter cleaning state, a feces cleaning state, a sand collection bin cleaning state and a deodorization cleaning state;

[0195] The control module 304 is used to control the cat litter box to stop executing the target operation corresponding to the working state when the first judgment module 303 determines that the cat litter box is in the working state.

[0196] It can be seen that the device described in the implementation of this optional embodiment can control the cat litter box to suspend the execution of corresponding operations when a pet enters the detection area if it is determined that the cat litter box is in working state, so as to reduce the possibility of the operation of the cat litter box harming the pet when the pet enters the detection area, thereby improving the operating safety of the cat litter box.

[0197] In another optional embodiment, the specific method of determining the pet toilet detection result corresponding to the cat litter box by the determination module 302 according to the stay time may include:

[0198] Determine whether the stay duration is greater than or equal to the preset duration;

[0199] When it is determined that the stay time is greater than or equal to the preset time, the pet toilet mark corresponding to the cat litter box is determined to be a valid toilet mark;

[0200] When it is determined that the stay time is less than the preset time, it is determined that the pet toilet mark corresponding to the cat litter box is an invalid toilet mark.

[0201] It can be seen that the device described in the implementation of this optional embodiment can determine the pet's toilet sign by judging whether the length of time the pet stays in the cat litter box is greater than or equal to the preset length of time, and when the judgment result is yes, the pet's toilet sign is determined to be a valid toilet sign, otherwise, the pet's toilet sign corresponding to the cat litter box is determined to be an invalid toilet sign, which can further improve the efficiency and accuracy of determining whether the pet goes to the toilet in the cat litter box, which is conducive to improving the accuracy of determining the pet's toilet sign, and thus is conducive to improving the timeliness and accuracy of cleaning the cat litter box.

[0202] In this optional embodiment, optionally, as Figure 5 As shown, the device may also include:

[0203] The second judgment module 305 is used to judge whether there is excrement corresponding to the target pet in the cat litter box after the determination module 302 determines that the residence time is greater than or equal to the preset time; when it is determined that there is excrement corresponding to the target pet in the cat litter box, the determination module 302 is triggered to execute the operation of determining that the toilet mark of the pet corresponding to the cat litter box is a valid toilet mark; when it is determined that there is no excrement corresponding to the target pet in the cat litter box, the determination module 302 is triggered to execute the operation of determining that the toilet mark of the pet corresponding to the cat litter box is an invalid toilet mark.

[0204] It can be seen that the device described in the implementation of this optional embodiment can also further determine whether there is excrement of the target pet in the cat litter box after determining that the stay time is greater than or equal to the preset time. If the judgment result is yes, the pet toilet mark is determined to be a valid toilet mark, otherwise, the pet toilet mark is determined to be an invalid toilet mark, which can reduce the possibility of judging the pet's stay in the cat litter box (such as resting or playing) as toilet behavior, thereby further improving the accuracy of determining whether the pet goes to the toilet in the cat litter box, and further improving the accuracy of determining the pet toilet mark.

[0205] In this optional embodiment, the second determination module 305 may determine whether there is excrement corresponding to the target pet in the cat litter box in a specific manner, which may include:

[0206] Obtaining pet information corresponding to the target pet, environmental information of the environment in which the cat litter box is located, and cat litter information of the cat litter placed in the cat litter box;

[0207] Analyze the expected temperature change result corresponding to the area inside the cat litter box according to the pet information, environmental information and cat litter information; the expected temperature change result is the estimated temperature change result corresponding to the area inside the cat litter box after the target pet defecates;

[0208] Determine the waiting time for feces detection corresponding to the cat litter box;

[0209] After the target pet is detected to have left the detection area, the actual temperature detection result corresponding to the area inside the cat litter box is detected within a time period corresponding to the waiting time for the defecation detection;

[0210] Determining the temperature change similarity between the expected temperature change result and the actual temperature detection result;

[0211] Determine whether the temperature change similarity is greater than or equal to a preset similarity;

[0212] When it is determined that the temperature change similarity is greater than or equal to the preset similarity, it is determined that there is excrement corresponding to the target pet in the cat litter box;

[0213] When it is determined that the temperature change similarity is less than the preset similarity, it is determined that there is no excrement corresponding to the target pet in the cat litter box.

[0214] It can be seen that the device described in the implementation of this optional embodiment can also analyze the expected temperature change result in the cat litter box according to the acquired pet information, environmental information and cat litter information, and then determine the waiting time for the defecation detection corresponding to the cat litter box, and after detecting that the target pet leaves the detection area and within the time period corresponding to the waiting time for the defecation detection, detect the actual temperature detection result in the cat litter box, and then determine the temperature change similarity between the expected temperature change result and the actual temperature detection result. When it is judged that the temperature change similarity is greater than or equal to the preset similarity, it is determined that there is defecation corresponding to the target pet in the cat litter box. Otherwise, it is determined that there is no defecation corresponding to the target pet in the cat litter box, which can improve the accuracy of the analysis of the temperature change of whether the pet defecates in the cat litter box. If the cat does not defecate in the cat litter box, the above-mentioned determined temperature change similarity will be lower, thereby improving the accuracy of determining whether there is defecation corresponding to the target pet in the cat litter box, which is conducive to further reducing the possibility of determining the behavior of the pet staying in the cat litter box (such as resting or playing) as toilet behavior, so as to further improve the accuracy of determining whether the pet goes to the toilet in the cat litter box.
