[0029] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0030] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0031] In the embodiments of the present disclosure, the terminal device refers to an electronic device with a wireless connection function. The terminal device can communicate with the smart home appliance by connecting to the Internet, or can communicate with the smart home appliance directly through Bluetooth, WiFi, etc. In some embodiments, the terminal device is, for example, a mobile device, a computer, or a vehicle-mounted device built into a hover car, or any combination thereof. Mobile devices may include, for example, mobile phones, smart home devices, wearable devices, smart mobile devices, virtual reality devices, etc., or any combination thereof, wherein wearable devices include, for example, smart watches, smart bracelets, pedometers, etc.

[0032] Figure 1 is a schematic diagram of a method for monitoring user status provided by an embodiment of the present disclosure; Figure 1 As shown, the embodiment of the present disclosure provides a method for monitoring user status, including:

[0033] S11, the monitoring device obtains the body motion signal collected by the millimeter wave radar monitoring device within a continuous time period.

[0034] S12, the monitoring device determines the local mark information and the global mark information in the monitoring area of ​​the millimeter wave radar monitoring device according to the body motion signal in the continuous time period.

[0035] S13, the monitoring device determines the user status within the monitoring area of ​​the millimeter wave radar monitoring device according to the local mark information and the global mark information.

[0036] In this solution, the monitoring device can be a millimeter wave radar monitoring device, or other monitoring devices associated with the millimeter wave radar monitoring device. Specifically, the monitoring device can obtain body motion signals within a continuous time period collected by the millimeter wave radar monitoring device. The continuous time period can be multiple adjacent periods starting from the previous moment to the current moment. For example, if the continuous time period includes 3 periods, the monitoring device can obtain body motion signals within 3 periods starting from the previous moment to the current moment collected by the millimeter wave radar monitoring device. In this way, the monitoring device can obtain body motion signals within a continuous time period more accurately.

[0037] Furthermore, the monitoring device can determine the local mark information and global mark information in the monitoring area of ​​the millimeter wave radar monitoring device in combination with the body motion signal in the continuous time period. Here, the local mark information can characterize the local micro-motion situation in the monitoring area, that is, it can indicate whether there is someone locally. As an example, the local mark information can be that there is someone locally or no one locally. The global mark information can characterize the global micro-motion situation in the monitoring area, that is, it can indicate whether there is someone globally in an active state and / or whether there is someone globally in a sleeping state. As an example, the global mark information can be that there is someone globally in an active state, no one globally in an active state, someone globally in a sleeping state, no one globally in a sleeping state, etc. Specifically, the local human condition, global activity condition, and global sleeping condition pre-stored in the monitoring device can be combined to determine the local mark information and global mark information that match the body motion signal in the continuous time period, providing an accurate data basis for determining the user status in the monitoring area of ​​the millimeter wave radar monitoring device.

[0038] Furthermore, the monitoring device can determine the user status within the monitoring area of ​​the millimeter-wave radar monitoring device in combination with the determined local marker information and the global marker information. Here, the user status can be determined by the user status determination rules pre-stored by the monitoring device. For example, the user status can be awake or asleep. In this way, the user status can be determined more accurately by the micro-movement in the monitoring area. With this solution, the inconvenience of wearing a wearable device when monitoring the status can be avoided, and the problem of insufficient aesthetics and poor accuracy due to long distance when opening a hole in the terminal device to install infrared monitoring is avoided. It also reduces the risk of privacy leakage during video monitoring, and has the characteristics of high accuracy and good reliability.

[0039] The method for monitoring the user status provided by the embodiment of the present disclosure is adopted, by obtaining the body motion signal collected by the millimeter wave radar monitoring device in a continuous time period, and combining the body motion signal in the continuous time period, determining the local mark information and global mark information in the monitoring area of ​​the millimeter wave radar monitoring device, thereby combining the determined local mark information and global mark information to determine the user status in the monitoring area of ​​the millimeter wave radar monitoring device. With this scheme, the micro-motion situation in the monitoring area can be determined in combination with the body motion signal collected by the millimeter wave radar monitoring device, and the user status can be accurately identified through the determined micro-motion situation, thereby realizing the non-sensing detection of the user status.

[0040] Optionally, S12, the monitoring device determines local sign information within the monitoring area of ​​the millimeter wave radar monitoring device according to the body motion signal within the continuous time period, including:

[0041] When the body motion signals within a continuous time period meet the local human condition, the monitoring device determines the local mark information as the local human presence; when the body motion signals within a continuous time period do not meet the local human condition, the monitoring device determines the local mark information as the local human presence.

[0042] In this solution, the local sign information and global sign information that match the body motion signal in the continuous time period can be determined in combination with the local occupancy condition pre-stored in the monitoring device. Specifically, if the body motion signal in the continuous time period meets the local occupancy condition, the local sign information is determined to be the local presence of a person; if the body motion signal in the continuous time period does not meet the local occupancy condition, the local sign information is determined to be the local absence of a person. In this way, the local micro-motion situation in the monitoring area can be determined more accurately in combination with the pre-stored local occupancy condition to determine whether there is a person in the monitoring area.

[0043] Figure 2 is a schematic diagram of a method for determining a local occupancy condition provided by an embodiment of the present disclosure; Figure 2As shown, the body motion signal in a continuous time period can be determined to meet the local human condition in the following way:

[0044] S21, the monitoring device obtains the number of signals whose signal strength is higher than the first motion strength in the body motion signals within a continuous time period.

[0045] S22, the monitoring device determines the ratio of the number of signals to the number of time periods as a first ratio.

[0046] S23, when the first ratio is not less than the first threshold, the monitoring device determines that the body motion signal within the continuous time period meets the local human condition.

[0047] In this solution, the signal strength of the body motion signal can be characterized by the number of micro-motion triggers per unit time. Specifically, the monitoring device can obtain the number of signals in the body motion signal within a continuous time period whose signal strength is higher than the first action strength, and determine the ratio of the number of signals to the number of time periods as the first ratio. For example, the body motion signals obtained within the continuous time period are 10, namely 45, 46, 47, 48, 43, 20, 23, 10, 4, and 9, respectively, the first action strength is 10, and the number of time periods is 10. Then, after screening out 7 of the 10 body motion signals with signal strengths higher than 10, the first ratio can be determined to be 7 / 10. Furthermore, when the first ratio is not less than the first threshold, it can be determined that the body motion signal within the continuous time period meets the local presence condition. As an example, the first threshold can be 1 / 8. In this way, the local micro-motion situation in the monitoring area can be judged under the condition of accurately setting the local presence condition to accurately determine whether there is anyone in the monitoring area.

[0048] Optionally, S12, the monitoring device determines global marker information within the monitoring area of ​​the millimeter wave radar monitoring device according to the body motion signal within the continuous time period, including:

[0049] When the body movement signals within a continuous time period meet the global activity conditions, the monitoring device determines the global flag information as someone is in an active state globally; when the body movement signals within a continuous time period meet the global sleep conditions, the monitoring device determines the global flag information as someone is in a sleeping state globally.

[0050] In this solution, global activity conditions and global sleep conditions can be pre-stored in the monitoring device, and global flag information that matches the body motion signal in a continuous time period can be determined. Specifically, if the body motion signal in a continuous time period meets the global activity condition, the global flag information is determined to be that someone is in an active state globally; if the body motion signal in a continuous time period meets the global sleep condition, the global flag information is determined to be that someone is in a sleeping state globally. In this way, the global micro-motion situation in the monitoring area can be determined more accurately in combination with the pre-stored global activity conditions and global sleep conditions to determine whether someone is in an active state or a sleeping state in the monitoring area.

[0051] Figure 3 is a schematic diagram of a method for determining a global activity condition provided by an embodiment of the present disclosure; Figure 3 As shown, optionally, it can be determined that the body motion signal in a continuous time period meets the global activity condition in the following manner:

[0052] S31, when the body motion signals in the continuous time period indicate that there is someone locally and the body motion signals in the continuous time period indicate that no one is active globally, the monitoring device obtains the number of signals in the body motion signals in the continuous time period whose signal strength is higher than the second action strength.

[0053] S32, the monitoring device determines the ratio of the number of signals to the number of time periods as a second ratio.

[0054] S33, when the second ratio is not less than the second threshold, the monitoring device determines that the body motion signal within the continuous time period meets the global activity condition.

[0055] In this solution, the number of signals with signal strength higher than the second action strength in the body motion signals in the continuous time period can be screened out on the premise that it is determined that the body motion signals in the continuous time period indicate that there are people locally and the body motion signals in the continuous time period indicate that no one is in an active state globally. Specifically, it can be determined that there are people locally when the body motion signals in the continuous time period meet the local human condition, and it can be determined that no one is in an active state globally when the cumulative duration of the body motion signals in the continuous time period indicating that no one is locally exceeds the first preset duration. Here, the first preset duration can be 15 minutes. Further, the monitoring device can screen out the number of signals with signal strength higher than the second action strength in the body motion signals, and determine the ratio of the number of signals to the number of time periods as the second ratio. For example, if there are 10 body motion signals in the continuous time period, the second action strength is 20, and the number of time periods is 5, then after screening out that the signal strength of 3 body motion signals out of 10 body motion signals is higher than 20, the second ratio can be determined to be 3 / 5. Further, it can be determined that the body motion signals in the continuous time period meet the global activity condition, that is, someone is in an active state globally, when the second ratio is not less than the second threshold. As an example, the second threshold value may be 5 / 9. In this way, the global micro-motion situation in the monitoring area can be judged under the condition of accurately setting the global activity condition, so as to accurately determine whether there is a person in the monitoring area in an active state.

[0056] Optionally, the body motion signal in a continuous time period may be determined to indicate that no one is in an active state globally by:

[0057] When the body motion signals in the continuous time period indicate that the accumulated time duration of local human presence exceeds the first preset time duration, the monitoring device determines that no one is active globally.

[0058] In this solution, when it is determined that the body motion signal in the continuous time period does not meet the local human condition, it is determined that the body motion signal in the continuous time period indicates that there is no human in the local area, so that when the cumulative duration of the local human existence exceeds the first preset duration, the monitoring device determines that no one is in an active state globally. As an example, the first preset duration can be 15 minutes. In this way, the local micro-motion situation in the monitoring area can be judged in combination with the local human condition, and it can be more accurately judged whether there is human activity globally.

[0059] Figure 4 is a schematic diagram of a method for determining a global sleep condition provided by an embodiment of the present disclosure; Figure 4 As shown, the body motion signal in a continuous time period can be determined to meet the global sleep condition in the following way:

[0060] S41, the monitoring device obtains the number of signals in body motion signals within a continuous time period whose signal strength is higher than the first motion strength and lower than the second motion strength.

[0061] S42, the monitoring device determines the ratio of the number of signals to the number of time periods as a third ratio.

[0062] S43: When the third ratio is not less than the third threshold, the monitoring device determines that the body movement signal within the continuous time period meets the global sleep condition.

[0063] In this solution, the signal strength of the body motion signal can be characterized by the number of micro-motion triggers per unit time. Specifically, the monitoring device can screen out the number of signals in the body motion signal within a continuous time period whose signal strength is higher than the first action strength and lower than the second action strength, and determine the ratio of the number of screened signals to the number of time periods as the third ratio. For example, the body motion signals acquired within a continuous time period are 20, the number of time periods is 20, the first action strength can be 10, and the second action strength can be 20. Then, when the signal strength of 14 of the 20 body motion signals screened out is between 10 and 20, the third ratio can be determined to be 14 / 20. Furthermore, when the third ratio is not less than the third threshold, it can be determined that the body motion signal within the continuous time period meets the global sleep condition. As an example, the third threshold can be 1 / 3. In this way, the global micro-motion situation in the monitoring area can be judged under the condition of setting the global sleep condition, so as to further determine whether someone in the monitoring area is in a sleeping state.

[0064] Optionally, in S13, the monitoring device determines the user status within the monitoring area of ​​the millimeter wave radar monitoring device according to the local flag information and the global flag information, including:

[0065] When the local flag information indicates that there is someone locally, the global flag information indicates that there is someone globally active, and the body movement signals within a continuous time period meet the global sleeping conditions, the monitoring device determines that the user state within the monitoring area of ​​the millimeter-wave radar monitoring device is in a sleeping state; when the local flag information indicates that there is no one locally, and the global flag information indicates that no one globally is sleeping, the monitoring device determines that the user state within the monitoring area of ​​the millimeter-wave radar monitoring device is in an awake state.

[0066] In this solution, in order to more accurately determine the state of the user in the monitoring area of ​​the monitoring device, the determination rules can be set in combination with the local micro-motion situation and the global micro-motion situation, so as to meet the accuracy requirements of user status monitoring through comprehensive consideration of multiple dimensions. Further, it can be stored in the monitoring device so that the monitoring device determines the user status through the user status determination rule. As an example, the user status determination rule may include that if the local flag information is that someone is locally present, the global flag information is that someone is globally active, and the body motion signal in a continuous time period meets the global sleep condition, the monitoring device determines that the user status in the monitoring area of ​​the millimeter-wave radar monitoring device is a sleeping state; if the local flag information is that no one is locally present, and the global flag information is that no one is globally in a sleeping state, the monitoring device determines that the user status in the monitoring area of ​​the millimeter-wave radar monitoring device is a wakeful state. In this way, the user status can be determined more accurately through the micro-motion situation in the monitoring area. This solution can eliminate the inconvenience of users having to wear wearable devices when monitoring status. It also avoids the problem of poor aesthetics and poor accuracy due to long distance when opening holes in terminal devices to install infrared monitoring. It also reduces the risk of privacy leakage during video monitoring and has the characteristics of high accuracy and good reliability.

[0068] The device for monitoring the user status provided by the embodiment of the present disclosure is used to obtain the body motion signal collected by the millimeter wave radar monitoring device in a continuous time period, and to determine the local mark information and global mark information in the monitoring area of ​​the millimeter wave radar monitoring device in combination with the body motion signal in the continuous time period, thereby combining the determined local mark information and global mark information to determine the user status in the monitoring area of ​​the millimeter wave radar monitoring device. With this solution, the micro-motion situation in the monitoring area can be determined in combination with the body motion signal collected by the millimeter wave radar monitoring device, and the user status can be accurately identified through the determined micro-motion situation, thereby realizing the non-sensing detection of the user status.
