Example 1

As shown in fig. 1, the method includes:

Step 101, detecting the brightness of light in a room.

In this embodiment, the lighting fixture may be in the form of a ceiling lamp, a wall lamp, or the like, and may be installed in a bedroom, a study room, or the like, and has access to a wireless access point.

The wireless access point is also called a session point or an access bridge, and not only includes a simple wireless access point (wireless AP), but also is a generic term for devices such as a wireless router (including a wireless gateway and a wireless bridge), and can be used for a wireless switch of a wireless network, and is also a core of the wireless network.

The lighting lamp is provided with a microwave radar, the microwave radar is used for carrying out non-contact detection, tracking and positioning on one or more objects through electromagnetic waves, the working frequency of the microwave radar is between 3MHz and 300GHz, and the wavelength of the microwave radar is between 100m and 1 mm.

In these rooms, a luminance sensor, i.e. a sensor that senses the luminance of light and converts it into a usable output signal, may be provided, which may detect the luminance of light in the room.

In some designs, the brightness sensor is a component of other intelligent home appliances in the room, at this time, the intelligent home appliances upload the brightness of the light in the room to the internet of things server and associate the brightness of the light in the room to the home of the user logged in at the intelligent home appliances, and the lighting fixture belongs to the intelligent device in the home, and can query the brightness of the light in the room from the internet of things server.

In other designs, the intensity sensor is a component of the light fixture, at which time the light fixture may invoke the intensity sensor at intervals to detect the intensity of light in the room.

Step 102, if the brightness is less than or equal to the preset first threshold, inquiring the user equipment accessed by the wireless access point.

And comparing the brightness of the light in the room with a preset first threshold value, if the brightness of the light in the room is larger than the first threshold value, indicating that the brightness of the light in the room is higher, and if the brightness of the light in the room is smaller than or equal to the first threshold value, indicating that the brightness of the light in the room is lower, inquiring the wireless access point about the user equipment which is connected with the wireless access point.

These user devices may be fixed devices, such as air conditioners, refrigerators, washing machines, etc., or mobile terminals, such as cell phones, smart wearable devices (e.g., watches, etc.), tablet computers, notebook computers, etc.

In one embodiment of the present invention, step 102 may include the steps of:

step 1021, request original authentication information from the wireless access point.

The lighting fixture may send a first authentication request to the wireless access point, and when the wireless access point receives the first authentication request, the wireless access point may generate unique original authentication information and send the original authentication information to the lighting fixture.

For example, the wireless access point generates a random number as the original authentication information.

For another example, the wireless access point generates a random number, and combines the random number and the current timestamp into the original authentication information according to a given arrangement.

For another example, the wireless access point generates a hash value for the current timestamp using an algorithm such as MD5 (Message Digest Algorithm, fifth version of message digest algorithm) as the original authentication information.

Step 1022, original verification information is sent to the internet of things server which is logged in by both the wireless access point and the lighting fixture.

Step 1023, receiving first target verification information obtained by signing the original verification information by the internet of things server by using a first key corresponding to the wireless access point.

The wireless access point and the lighting fixture belong to the same internet of things platform, and the internet of things platform can belong to a manufacturer for producing the wireless access point and/or the lighting fixture, and also can belong to a third party manufacturer, which is not limited in this embodiment.

The lighting lamp can send a second verification request to an internet of things server in the internet of things platform, the second verification request carries the identification of the lighting lamp, the identification of the wireless access point and original verification information, when the internet of things server receives the second verification request, the relation between the lighting lamp (expressed by the identification) and the wireless access point (expressed by the identification) is verified, if the relation is the same house of the same user as the lighting lamp (expressed by the identification) and the wireless access point (expressed by the identification), a secret key configured for the wireless access point is inquired, the secret key is used for signing the original verification information, first target verification information is obtained, and the first target verification information is sent to the lighting lamp.

Step 1024, send the first target authentication information to the wireless access point.

Step 1025, when the wireless access point performs the verification operation successfully, controlling the lighting lamp to establish a wireless link with the wireless access point.

The lighting lamp can send a third verification request to the wireless access point, the third verification request carries the first target verification information, when the wireless access point receives the third verification request, verification operation is executed, the verification operation is that the wireless access point signs the original verification information by using a local secret key to obtain second target verification information, and the first target verification information is compared with the second target verification information.

When the verification operation is successfully executed, the lighting lamp and the wireless access point establish an independent wireless link, and the independent wireless link indicates that the user has authorized the lighting lamp to use part of the information of the wireless access point in advance.

The verification operation successfully indicates that the wireless access point signs the original verification information by using a local key to obtain second target verification information, and the first target verification information is identical to the second target verification information.

Step 1026, receiving, via the wireless link, the accessed user equipment sent by the wireless access point.

The lighting fixture may send a query request to the wireless access point via the wireless link, and the wireless access point queries the user device (represented by information such as a name) that is currently accessed when receiving the query request, and sends the information (such as the name) of the user device to the lighting fixture via the wireless link.

Step 1027, searching a list of devices for room learning.

The lighting fixtures may historically communicate with the wireless access point periodically, record the user devices that access it, form a list of devices that are stored in the lighting fixtures, indicating the user devices that have entered the house and possibly the room.

Step 1028, user equipment belonging to the mobile terminal carried by the user belonging to the room is screened out from the equipment list.

Each user equipment in the equipment list has multidimensional information such as names, login time length, login frequency and the like, and the characteristics of the user equipment can be reflected to a certain extent by integrating the information, so that user equipment possibly belonging to a mobile terminal carried by a user belonging to a room is screened out from all the user equipment.

In a specific implementation, the information recorded in the device list includes a name of the user device, a time when the user device accesses the wireless hotspot, and so on.

Then, the user equipment accessing the wireless access point in the last multiple time periods (the time period is a periodic time period, such as 1 natural day) is selected from the device list as the first candidate device, that is, the time of the first candidate device accessing the wireless hotspot is in the last multiple time periods.

Because the names of the user equipment contain equipment models in many ways, the equipment models of the mobile terminals can be collected in advance, so that the first candidate equipment with the names representing the mobile terminals is screened out from the equipment list and used as the second candidate equipment, namely, at least part of fields of the names of the second candidate equipment are the same as the equipment models of the mobile terminals, and intelligent household appliances such as air conditioners, refrigerators and washing machines, which are connected with wireless access points in the long term can be eliminated.

And counting the frequency of the second candidate device accessing the wireless access point in each time period in the latest time periods.

If the frequency value of a certain second candidate device in a certain time period is zero, the user to which the second candidate device belongs is highly likely to not enter the house in the time period, and the user to which the second candidate device belongs is likely to belong to the visitor.

And if the frequency of which the value is not zero is larger than a preset third threshold value (which indicates that the second candidate device accesses the wireless access point for a long time) and the number of the frequency is larger than a preset fourth threshold value (which indicates that the second candidate device frequently accesses the wireless access point), the probability that the user to which the second candidate device belongs to the visitor is lower, otherwise, the probability that the user to which the second candidate device belongs to the owner of the room (house) is higher, and the mobile terminal carried by the user to which the second candidate device belongs can be determined.

Step 103, if the user equipment includes a mobile terminal carried by a user belonging to the room, respectively starting the first learning machine, the second learning machine and the third learning machine.

In general, the wireless hot spot is equipment which operates for a long time, so that the wireless hot spot can indirectly reflect the activity condition of a user in multiple aspects, can be used as an anchor point for detecting the activity condition of the user, and can avoid the long-time operation of the microwave radar by the lighting lamp.

However, the accuracy of detecting the activity condition of the user by the single-aspect information provided by the wireless hotspot is low, and then, in this embodiment, reinforcement learning may be applied, and a plurality of weak learning machines including a first learning machine, a second learning machine, and a third learning machine may be respectively provided.

The first learning machine is used for detecting a first state of the mobile terminal from the wireless access point.

The second learning machine is configured to detect a second state of a door of the room based on a broadcast signal transmitted by the wireless access point.

The third learning machine is used for detecting a third state of the broadcast signal.

The first learning machine, the second learning machine and the third learning machine are aggregated into a strong learning machine, so that the accuracy of detecting the activity condition of the user is improved.

In a specific implementation, if the mobile terminal carried by the user to which the room belongs is detected, which indicates that the requirement of the user for using the lighting lamp is likely to occur, the first learning machine can be started in an independent process respectively, the first learning machine detects the first state of the mobile terminal to the wireless access point, the second learning machine is started in another independent process, the second learning machine detects the second state of the door of the room according to the broadcast signal transmitted by the wireless access point, and the third learning machine is started in another independent process, and the third learning machine detects the third state of the broadcast signal.

In one embodiment of the present invention, step 103 may include the steps of:

step S31, starting the first learning machine, and sending a jump inquiry request to the wireless access point for the mobile terminal through the wireless link.

And step S32, if the wireless access point is a wireless mesh network, receiving a node which is returned by the wireless access point in response to the jump inquiry request and is accessed by the mobile terminal in the wireless mesh network through a wireless link.

Step S33, if the node changes, the first state of the mobile terminal is determined to be mobile.

In this embodiment, the wireless access point is a wireless Mesh network (Mesh network), in which there are multiple nodes, and the user arranges the multiple nodes at different positions according to the layout of the house, so that the Mesh network can cover the house, any node can be used as an AP and a router at the same time, each node in the Mesh network can send and receive signals, and each node can directly communicate with one or more peer nodes.

The first learning machine in the lighting lamp sends a jump inquiry request to the wireless access point through an independent wireless link for the mobile terminal, the wireless access point checks a node which is accessed by the mobile terminal in a Mesh network in the latest time when receiving the jump inquiry request, the node is sent to the lighting lamp through the independent wireless link, and the lighting lamp judges whether the node which is accessed by the mobile terminal in the latest time in the Mesh network changes or not.

If the node accessed by the mobile terminal in the Mesh network in the latest period of time changes, the mobile terminal can be determined to be carried by the user to move in a large range, so that the first state of the mobile terminal is determined to be moving.

If the node accessed by the mobile terminal in the Mesh network in the latest period of time is unchanged, the small-range round trip of the mobile terminal carried by the user can be determined, so that the first state of the mobile terminal is determined to be static.

In one embodiment of the present invention, step 103 may include the steps of:

step S41, starting a second learning machine, and reading the first signal strength of the broadcast signal transmitted by the wireless access point.

Step S42, calculating an average value from the first signal intensity as an average intensity.

Step S43, calculating the difference between the original signal intensity and the average intensity as the intensity difference.

Step S44, taking a specified proportion of the average intensity as a fifth threshold.

Step S45, if the intensity difference is larger than a fifth threshold value, determining that a second state of the door of the room is open and closed.

In general, the placement position of the wireless access point and the installation position of the lighting fixture are fixed, and most household appliances in the house are also fixed, and because the lighting fixture is in the room, the movable barrier at intervals between the wireless access point and the lighting fixture is mainly a door of the room, and the strength of a broadcast signal emitted by the wireless access point has obvious attenuation when penetrating the door of the room, and is particularly obvious when the door of the room is made of metal.

The wireless access point periodically transmits a broadcast signal to the outside, and the broadcast signal contains information such as SSID (Service Set Identifier ) and the like, so that other devices receiving the broadcast signal access the wireless access point according to protocols such as WiFi (wireless fidelity).

In this embodiment, the second learning machine in the lighting fixture reads the strength of the broadcast signal received from the wireless access point, and records the strength as the first signal strength, that is, the first signal strength belongs to the received signal strength (Received Signal Strength Indicator, RSSI).

Since the wireless access point has a certain fluctuation in the broadcast signal transmitted to the outside, as the intensity difference, an average value is calculated from the first signal intensities of the plurality of frames, as the average intensity, and a specified ratio is taken as the fifth threshold value.

To increase the sensitivity of the fifth threshold to detection, the ratio may take a smaller percentage, such as 10%.

At this time, a difference between the original signal intensity and the average intensity may be calculated, and if a certain frame intensity difference is greater than a fifth threshold value, it may be determined that the second state of the door of the room is open and closed, wherein the open and closed is one action, indicating that the door is opened from the closed time or closed from the opened time, indicating that the amplitude of the first received signal intensity fluctuation is large.

Further, the door of the room is opened when being closed, the first signal intensity is greatly improved at the moment of opening, the door of the room is closed when being opened, and the first signal intensity is greatly reduced at the moment of closing.

If the difference in the intensity of a certain frame is less than or equal to the fifth threshold value, which indicates that the amplitude of the first received signal intensity fluctuation is small, it is determined that the second state of the door of the room is not open or closed.

In one embodiment of the present invention, step 103 may include the steps of:

step S51, starting a third learning machine, and extracting first signal features in time domain and frequency domain from the current broadcast signal.

Step S52, extracting a history signal.

The history signal is a broadcast signal recorded for the wireless access point when the human body exists in the room history, and the history signal is related to the second signal strength and the second signal characteristics in the time domain and the frequency domain.

Step S53, calculating the relative entropy between the first signal intensity and the second signal intensity.

Step S54, calculating pearson correlation coefficients between the first signal characteristic and the second signal characteristic.

Step S55, the relative entropy and the Pearson correlation coefficient are linearly fused into the similarity between the current broadcast signal and the historical signal.

Step S56, if the similarity is greater than or equal to a preset sixth threshold, determining that the third state of the broadcast signal is human body interference.

If a user walks between the wireless access point and the lighting fixture, a certain disturbance exists in the broadcast signal received by the lighting fixture and transmitted by the wireless access point, and the disturbance is caused by irregular human body interference.

In this embodiment, the third learning machine in the lighting fixture performs inter-process communication with the second learning machine to obtain the first signal strength of the broadcast signal transmitted by the wireless access point, and in addition, extracts the first signal features of the current broadcast signal in the time domain and the frequency domain.

To improve the sensitivity of the detection, the first signal characteristic is mostly a statistical characteristic, e.g. period in time sequence, amplitude in frequency domain, etc.

When the lighting fixture historically detects that a user exists in a room (namely human body interference exists) by using the microwave radar, the broadcasting signal transmitted by the wireless access point is recorded as a historical signal, accordingly, the strength of the received historical signal is recorded as second signal strength, and second signal characteristics in the time domain and the frequency domain are extracted for the historical signal.

On the one hand, the relative entropy (also called KL (Kullback-Leibler) divergence) between the first signal intensity and the second signal intensity is calculated, and the difference degree of the current broadcast signal and the historical signal on the intensity distribution is measured.

On the other hand, a pearson correlation coefficient (Pearson correlation coefficient) between the first signal characteristic and the second signal characteristic is calculated, and the correlation degree of the current broadcast signal and the historical signal in the time domain and the frequency domain is measured.

At this time, the relative entropy and the pearson correlation coefficient are linearly fused as the similarity between the current broadcast signal and the history signal, the fusion being expressed as follows:

Sim=α×KL+β×PCCs

wherein Sim is similarity, KL is relative entropy, PCCs is pearson correlation coefficient, alpha and beta are weights, and in general, alpha is larger than beta.

If the similarity is greater than or equal to a preset sixth threshold, which indicates that the similarity between the current broadcast signal and the history signal is high, it may be determined that the third state of the broadcast signal is human body interference.

If the similarity is smaller than a preset sixth threshold, which indicates that the similarity between the current broadcast signal and the history signal is lower, it may be determined that the third state of the broadcast signal is that there is no human body interference.

The sixth threshold may be a smaller value in order to increase the sensitivity of detection.

And 104, adding unified windows to the first state, the second state and the third state on a time axis, and moving the windows.

In this embodiment, the first state, the second state, and the third state each have a time stamp, the first state, the second state, and the third state are marked on a time axis according to the time stamps, a window is added on the time axis, and the window is moved according to a specified step size.

Typically, the step size of the movement is smaller than the length of the window.

Step 105, if the first state is moving, the second state is open and close, and the third state is that the duty ratio of human interference exceeds a preset second threshold value, the lighting lamp is controlled to emit light according to the first lighting mode.

When the window is moved each time, the first state in the window is moving, the second state is open and close, and the third state is the ratio of the human body interference, namely the ratio of the first state belonging to the moving to all the first states, the ratio of the second state belonging to the open and close to all the second states, and the ratio of the third state belonging to the human body interference to all the third states can be judged.

If the first state is moving, the second state is open and close, and the third state is that the duty ratio of human body interference exceeds a preset second threshold value, the situation that a user walks in a room (particularly a room) and the possibility of certain use of the lighting lamp exists is indicated, and at the moment, the lighting lamp is controlled to emit light according to a first lighting mode.

The first lighting mode comprises a first brightness value and a first color temperature value, namely, the first brightness value and the first color temperature value of the lighting lamp are controlled to emit light.

Further, the first illumination mode is a low-power consumption mode, at this time, the first brightness value is lower, so that the consumption of electric energy can be saved, and in a low-light environment, the light in the low-power consumption mode can reduce the irritation to eyes of a user.

And 106, driving the microwave radar to scan the room so as to obtain a fourth state of the human body when the human body exists in the room.

The antenna of the microwave radar emits an electromagnetic wave signal in the form of microwaves, which moves at the speed of light, and when the electromagnetic wave signal hits an object, the electromagnetic wave signal changes and is reflected back to the microwave radar. The electromagnetic wave signal arriving at the antenna of the microwave radar contains information about the detected object.

In the running process of the lighting lamp, the microwave radar can be continuously controlled to emit multi-frame electromagnetic wave signals to the room, and then the microwave radar can continuously receive multi-frame electromagnetic wave signals reflected by different objects such as furniture, household appliances, walls, human bodies and the like in the room.

The objects except the user are mostly static, the user is mostly dynamic, limbs are mostly swung to a certain extent, namely, the human body is mostly moved to a certain extent, so that each frame of electromagnetic wave signal can be detected by taking the user as a target through a target detection network, a dynamic tracking model and the like, the user is detected, tracked, and the information of the gesture, the position and the like of the user is detected.

Based on deep learning, machine learning (such as SVM (Support Vector Machine, support vector machine) and other classifiers) or rules, a fourth state of the user can be identified according to electromagnetic wave signals, gestures and positions of the user and other information, wherein the fourth state mainly comprises a static state (including a static region) and a motion state (including a motion region).

Step 107, controlling the lighting lamp to switch from the first lighting mode to the second lighting mode adapted to the fourth state to emit light.

The user is in different fourth states, and there is certain difference to the demand of light, therefore, in this embodiment, the second illumination mode can be set up in advance through modes such as experiments to different fourth states, and the light of the second illumination mode can make the user obtain better illumination experience in the fourth state.

Then, the lighting fixture may be controlled to switch from a first lighting mode to a second lighting mode adapted to the fourth state to emit light, wherein the second lighting mode is a normal lighting mode, and the power consumption of the first lighting mode is lower than the power consumption of the second lighting mode.

Further, the lighting lamp can be directly switched to the second lighting mode adapted to the fourth state from the first lighting mode to emit light, and can also be gradually switched to the second lighting mode adapted to the fourth state from the first lighting mode to emit light, so that the irritation to eyes of a user is reduced, and the embodiment is not limited to the above.

During progressive switching, a mapping table may be loaded, the mapping table records a relation of mapping the fourth state to the second illumination mode, and the second illumination mode adapted to the fourth state is queried in the mapping table, wherein the second illumination mode includes a second brightness value and a second color temperature value.

The difference between the first luminance value and the second luminance value is calculated as a luminance difference, and the difference between the first color temperature value and the second color temperature value is calculated as a color temperature difference, respectively.

In general, the luminance difference is more remarkable than the chromaticity difference, and therefore, a plurality of control points can be generated based on the luminance difference, wherein the number of control points is positively correlated with the luminance difference, that is, the greater the luminance difference is, the greater the number of control points is, the smaller the luminance difference is, the number of control points is smaller, and in addition, the time length of the interval between two adjacent control points is positively correlated with the luminance difference, that is, the greater the luminance difference is, the greater the time length of the interval between two adjacent control points is, the smaller the luminance difference is, and the time length of the interval between two adjacent control points is smaller.

A first ratio between the brightness difference and the number of the regulation points is calculated, and a second ratio between the color temperature difference and the number of the regulation points is calculated.

And configuring brightness and color temperature for the regulating points in sequence, wherein the initial value of the brightness is a first brightness value, the first ratio is sequentially increased on the basis of the first brightness value (namely, the first ratio is increased once every interval of one regulating point) until the second brightness is reached, the initial value of the color temperature is a first color temperature value, the second ratio is sequentially increased on the basis of the first color temperature value (namely, the second ratio is increased once every interval of one regulating point) until the second color temperature value is reached.

And then, controlling the lighting lamp to emit light according to the brightness and the color temperature in the regulation point in sequence.

In one way of adjusting the brightness and color temperature, the lighting fixture outputs two light sources, one being warm light (color temperature about 3000K) and one being cold light (white, color temperature about 7000K). Each light source is independent, the output current of the light source is regulated by regulating the duty ratio of PWM (Pulse width modulation ) signals, the different brightness of each light source is regulated, and the two light sources are fully mixed, so that the adjustment of the color temperature and the adjustment of the brightness of the light of the whole lighting lamp are realized.

For example, the color temperature of the mixed light in the lighting fixture is about 5000K (not very cool white, but a single spot of warm white) because the light in the path A is warm light with the color temperature of 3000K, but the brightness is only 10% of the full brightness, and the light in the path B is cold light with the brightness of only 40% of the full brightness.
