Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0052] The method for determining the state of a target within a building, as provided in this application, will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0053] Figure 1 This is a flowchart illustrating a method for determining the state of a target within a building, as provided by the present invention. Figure 1 As shown, the present invention provides a method for determining the state of a target within a building, which may include the following steps.

[0054] Optionally, the following steps may be implemented by a microprocessor, a computer, or similar device. Further, the microprocessor is housed within a sensor assembly, integrated with multiple different types of sensors within the same housing, and is used to receive and analyze sensor data.

[0055] S100: Acquire sensing data for a predetermined space within a building based on multiple different types of sensors.

[0056] Optionally, the sensors include millimeter-wave radar, pyroelectric sensors, illuminance sensors, temperature sensors, humidity sensors, barometric pressure sensors, digital gyroscopes, gravity sensors, and mercury switches.

[0057] By acquiring sensor data from various types of sensors, the input data of the subsequent neural network becomes more dimensional, thus increasing the possibility of reducing false detections.

[0058] S200. Input the sensing data into the target existence judgment model, and the target existence judgment model outputs the judgment information on the target state within the predetermined space.

[0059] Optionally, before the sensor data is input into the target judgment model, the sensor data needs to be angled. The angle adjustment is based on the installation angle of the sensor assembly, which is specifically obtained by the installation angle sensor installed in the sensor assembly.

[0060] Preferably, the installation angle sensor includes at least one of the following:

[0061] The device includes a digital gyroscope, a gravity sensor, and mercury switches. Preferably, there can be one or more mercury switches; for example, when three mercury switches are installed in the sensor assembly, the microprocessor can acquire three preliminary angle signals. Based on these three preliminary angle signals, the microprocessor can calculate a more precise installation angle for the device. Mercury switches can save costs.

[0062] Optionally, the target state can be one of several pre-designed target states.

[0063] Optionally, the neural network is trained to determine the state of a target within a predetermined space based on the aforementioned sensor data.

[0064] Optionally, by reproducing common target state scenarios, the collected dataset is split into training, validation, and test sets for training the corresponding algorithm models. The trained models are then cross-validated with the validation and test sets to ensure that the computational results do not exhibit overfitting or underfitting. During training, the loss function is obtained based on the difference between manually labeled samples and the training output.

[0065] Optionally, the target is a person, and the target state includes the target not existing within the predetermined space.

[0066] This embodiment uses sensor data obtained from various types of sensors and then performs a comprehensive judgment on the target state based on a neural network, which improves the accuracy of judging whether the target exists and can further determine the target's state.

[0067] Furthermore, based on the foregoing embodiments, in another embodiment, this embodiment provides a method for determining the state of a target within a building, wherein the sensing data includes: spatial environment data;

[0068] Correspondingly, the sensor data is input into the target storage judgment model, including:

[0069] Based on spatial environment data, generate data on whether the environment is comfortable;

[0070] Input the data on whether the environment is comfortable into the target existence judgment model.

[0071] This embodiment uses spatial environment data to determine whether the environment is comfortable. It leverages the human instinct to gravitate towards comfortable environments, thereby inferring human behavior (i.e., the target state) based on the environment, thus improving the accuracy of the target existence judgment model.

[0072] Furthermore, based on the foregoing embodiments, in another embodiment, this embodiment provides a method for determining the state of a target within a building, wherein the spatial environment data includes at least one of the following:

[0073] Space temperature data, space illuminance data, space humidity data, space air pressure data.

[0074] This embodiment discloses four specific data points that affect environmental comfort, which can be obtained from a light intensity sensor, a temperature sensor, a humidity sensor, and a barometric pressure sensor.

[0075] Furthermore, based on the foregoing embodiments, in another embodiment, this embodiment provides a method for determining the state of a target within a building, generating environmental comfort data based on spatial environment data, including:

[0076] Obtain a pre-set human comfort environment model;

[0077] The spatial environment data is input into the human comfort environment model, and the human comfort environment model outputs the judgment result, which is used as the data on whether the environment is comfortable.

[0078] Optionally, the human comfort environment model is a function of four independent variables: spatial temperature data, spatial illuminance data, spatial humidity data, and spatial air pressure data, with the dependent variable being whether the environment is comfortable.

[0079] Alternatively, the human comfort environment model may employ another neural network model.

[0080] This embodiment discloses a method for obtaining data on whether the environment is comfortable.

[0081] Furthermore, based on the foregoing embodiments, in another embodiment, this embodiment provides a method for determining the state of a target within a building, wherein the sensing data includes: infrared data;

[0082] The infrared data was acquired by monitoring a pyroelectric sensor in a predetermined space.

[0083] All sensor data are time-series data;

[0084] Correspondingly, the sensor data is input into the target storage judgment model, including:

[0085] The infrared data is preprocessed to form the first processing result data;

[0086] Input the first processing result data into the target existence judgment model;

[0087] The first processing result data includes: whether there was biological movement within the time period.

[0088] Optionally, whether there is biological movement within a time period can be determined by the type of the result output by the fully connected layer, or by the probability type without processing by the fully connected layer.

[0089] Optionally, infrared data can be preprocessed using an infrared time-series calculation model. This reduces the computational load of the target presence determination model.

[0090] Optionally, instead of using an infrared time-series calculation model to preprocess the infrared data, the time-series infrared data can be directly input into the target presence determination model. This improves the accuracy of the target presence determination model.

[0091] This embodiment utilizes the ability of infrared data to accurately determine whether there are living organisms in a predetermined space and whether the organisms are moving, thereby screening, filtering out, or downweighting the impact of false detections of non-biological activities by other non-pyroelectric sensors on the output of the neural network.

[0092] Furthermore, based on the foregoing embodiments, in another embodiment, this embodiment provides a method for determining the state of a target within a building, wherein the sensing data includes: radar echo data;

[0093] The radar echo data was obtained by monitoring millimeter-wave radar in a predetermined space.

[0094] All sensor data are time-series data;

[0095] Correspondingly, the sensor data is input into the target storage judgment model, including:

[0096] The radar echo data is preprocessed to form the second processing result data.

[0097] The second processing result data is input into the target existence judgment model;

[0098] The second processing result data includes at least one of the following:

[0099] Whether the millimeter-wave radar detected the target, the distance between the target and the millimeter-wave radar, the target's moving speed, and the target's moving range.

[0100] Optionally, whether the millimeter-wave radar detects a target can be determined by the type of result output from the fully connected layer, or by the probability type without processing by the fully connected layer.

[0101] Optionally, the radar echo data can be preprocessed using a millimeter-wave echo calculation model. Preferably, the installation angle is used as one of the original parameters input into the millimeter-wave echo calculation model to compensate for differences in the installation environment.

[0102] This embodiment utilizes the precise detection capability of millimeter-wave radar for small-amplitude target movements, enabling the neural network to output a more specific state of the target (compared to whether it exists or not).

[0103] Furthermore, based on the foregoing embodiments, in another embodiment, this embodiment provides a method for determining the state of a target within a building, wherein the determination information includes at least any one of the following:

[0104] The target does not exist in the predetermined space; the target exists in the predetermined space; the target is entering the predetermined space; the target exists in the predetermined space and is approaching the sensor; the target exists in the predetermined space and is moving away from the sensor; the target is in a relatively slightly moving state; the target is in a relatively stationary state; the target changes from a relatively stationary state to approaching the sensor; the target changes from a relatively stationary state to moving away from the sensor.

[0105] Among them, the target being in a relatively micro-motion state means that the target remains in place and performs the first activity, the magnitude of which is greater than a predetermined threshold.

[0106] The target being in a relatively static state means that the target remains in place and performs a second activity, the magnitude of which is less than or equal to a predetermined threshold.

[0107] Optionally, the judgment information can be the result of the fully connected layer output, or it can be a probability type that has not been processed by the fully connected layer.

[0108] Optionally, based on each time window of the time series, the probability of various target states output by the target existence judgment model is used to determine the further target states through a fully connected layer, forming the final target state under that time window. Furthermore, judgment information is formed based on the final target states under multiple time series.

[0109] Optionally, the first activity includes work, study, and entertainment.

[0110] Optionally, the second activity includes sleep and rest.

[0111] The movement of a target from a relatively stationary state to approaching the sensor, or from a relatively stationary state to moving away from the sensor, helps determine whether the target human body is in a sleep state before moving. This can help intelligent buildings prepare in advance for the subsequent linkage control of lights, air conditioning, curtains, etc.

[0112] This embodiment demonstrates that neural networks can output more accurate and specific target state information.

[0113] Furthermore, based on the foregoing embodiments, in another embodiment, this embodiment provides a method for determining the state of a target within a building, wherein the target existence determination model includes at least one of the following:

[0114] Linear regression, logistic regression, decision trees, random forests, k-nearest neighbors algorithm, hidden Markov models, convolutional neural networks, recurrent neural networks, and long short-term memory networks.

[0115] Optionally, the Hidden Markov Model (HMM) can be a supervised HMM.

[0116] Optionally, the sensor data (time series data) constitutes the observation sequence of the HMM, and judgment information is formed based on the state sequence output by the HMM.

[0117] This embodiment reduces the amount of data computation by using a hidden Markov model, thereby enabling real-time target judgment on a microprocessor.

[0118] Furthermore, based on the foregoing embodiments, in another embodiment, this embodiment provides a method for determining the state of a target within a building. The target presence determination model is updated using wired or wireless methods. By updating the target presence determination model, the accuracy of the determination is continuously improved.

[0119] Furthermore, based on the foregoing embodiments, in another embodiment, this embodiment provides a method for determining the state of a target within a building, wherein the sensing data includes time-series input data, the determination information includes corresponding time-series output data, and the method further includes:

[0120] Based on multiple consecutive single-instance data points in the time series output data, comprehensive judgment data for time periods is formed.

[0121] This embodiment utilizes the continuity of time to obtain comprehensive judgment data based on time periods, thereby improving the accuracy of judgments. Furthermore, the comprehensive judgment data can be used to reverse-correct some input data, thereby improving the accuracy of other judgment information obtained based on the input data.

[0122] It should be noted that, optionally, the datasets used in the aforementioned infrared time-series calculation model, millimeter-wave echo calculation model, human comfort environment model, and target presence judgment model can be collected in the laboratory, pre-trained, and the results stored on the user terminal as preset models; optionally, the datasets used in the aforementioned infrared time-series calculation model, millimeter-wave echo calculation model, human comfort environment model, and target presence judgment model can be collected by the user terminal and the results retrained locally on the user's device.

[0127] This embodiment uses sensor data obtained from various types of sensors and then performs a comprehensive judgment on the target state based on a neural network, which improves the accuracy of judging whether the target exists and can further determine the target's state.

[0128] After obtaining the judgment information of the target state based on the judgment method in this example, various control functions can be implemented, including:

[0131] When the target exists in the predetermined space and is in a relatively slightly moving state, and the current illuminance is strong, based on the local sunset time and the user's historical habits, instructions such as dimming the lights and closing the blackout curtains are issued to the lights and curtains in the building to achieve the purpose of comfortable control of ambient light.

[0134] When the target does not exist in the designated space, a shutdown command is issued to all smart devices within the building to achieve energy-saving control. In this state, noisy equipment such as sweeping robots can also be activated to provide a more comfortable and efficient cleaning experience.
