[0011] like Figure 1 and Figure 2 As shown, this embodiment provides an intelligent LED linear high bay light, including a power supply component, a light source component, a heat sink, a control circuit, and a DIP switch board, wherein the power supply component is connected to the heat sink, and the light source component is connected to the heat sink; The DIP switch board includes a DIP switch for adjusting the power of the smart LED linear high bay light, and a switch for adjusting the color temperature of the smart LED linear high bay light. Since the brightness of the smart LED linear high bay light is positively correlated with its power, the brightness of the smart LED linear high bay light can be adjusted by adjusting the power of the smart LED linear high bay light. In actual use, the power and color temperature of the smart LED linear high bay light can be adjusted using the DIP switch according to the application scenario to meet different scene requirements.

[0012] In this embodiment, the light source assembly includes a lamp bead, an aluminum substrate and a lens, the lamp bead is mounted on the aluminum substrate, a light source mounting compartment is provided on the heat sink, the lens is connected to the heat sink by a buckle, and the aluminum substrate and the lamp bead are located in the light source mounting compartment; The lens in this embodiment is designed to be disassembled and assembled without tools or screws, is connected to the heat sink by a snap-on self-locking method, and provides a variety of lenses with different angles to choose from and replace to meet different usage scenarios.

[0013] like Figure 2 As shown, the heat sink also includes a power supply installation compartment, the power supply assembly is installed in the power supply installation compartment, the outer wall of the light source installation compartment is provided with a heat dissipation structure, the light source assembly and the power supply assembly are at a preset distance, and a heat convection groove is provided between the light source installation compartment and the power supply installation compartment; The heat dissipation structure may adopt a heat dissipation plate arranged on the back of the light source installation compartment. The heat dissipation structure can accelerate the heat exchange between the heat sink and the surrounding environment, thereby improving the heat dissipation effect of the LED linear high bay light. Since the present embodiment makes the light source assembly and the power supply assembly separated by a preset distance, and a heat convection groove is arranged between the light source installation compartment and the power supply installation compartment, a heat convection space is formed in the power supply installation compartment and the light source installation compartment, so that the heat dissipation of the power supply and the heat dissipation of the lamp beads are separated, the interference of heat is reduced, and the life of the power supply can be effectively improved, thereby increasing the total life of the lamp. The dial switch board can also be installed in the power supply installation compartment to facilitate user operation.

[0014] In order to meet different installation requirements of users, the smart LED linear high bay light of this embodiment further includes a hanging assembly and / or a ceiling mounting assembly and / or a surface mounting assembly.

The hanging assembly includes a Y-shaped lifting wire rope and a mounting member, and the Y-shaped lifting wire rope passes through the mounting hole of the heat sink and is connected to the mounting member. The smart LED linear high bay light can be installed under the ceiling by the Y-shaped lifting wire rope.

[0016] like Figure 4 As shown, the ceiling mounting assembly is used to mount the smart LED linear high bay light in this embodiment below the ceiling in a ceiling mounting manner. The ceiling mounting assembly includes a base and a ceiling box, the base is mounted on the upper surface of the heat sink, and the ceiling is mounted on the base; like Figure 5 As shown, the surface mounting component is used to mount the LED linear high bay light in this embodiment on the surface of an object, and the surface mounting component includes a mounting plate and a hook, the upper part of the hook is arranged in the strip groove of the mounting plate, and the mounting hole of the heat sink is hung on the lower part of the hook.

[0017] like Figure 6 As shown, the LED linear high bay light in this embodiment also includes an emergency power supply, which is installed above the heat sink and is electrically connected to the control circuit. Normally, the LED linear high bay light is powered by a common power supply in the power supply installation compartment. In an emergency situation where the conventional power supply cannot supply power, the emergency power supply can be switched to supply power.

[0018] The control circuit is electrically connected to the power supply assembly and the light source assembly respectively, and the dip switch board is electrically connected to the control circuit. The dip switch board is used to adjust the brightness and color temperature of the smart LED linear high bay light by dialing; the control circuit is used to control the brightness of the smart LED linear high bay light according to the control mode of the smart LED linear high bay light.

[0019] In this embodiment, a base is provided at the bottom of the smart LED linear high bay light, wherein the base is provided with a microwave sensor interface, and the interface can be installed with a microwave sensor for detecting human movement.

[0020] The control circuit is also used to control the switching state and brightness of the smart LED linear high bay lights used for lighting each target area according to the current control mode of the smart LED linear high bay lights combined with the detection results of human body movement. The control mode includes a light priority mode and a light uncontrolled mode.

[0021] If the current control mode of the smart LED linear high bay light is the light sensing priority mode, obtain the preset light turn-on value; Detecting the ambient light brightness in the target area; If it is detected that the ambient light brightness in the target area is less than the preset light-on value, the smart LED linear high-bay light corresponding to the target detection area is turned on, and the brightness of the smart light is controlled to maintain at the standby brightness; When the microwave sensor detects that a human body is moving toward the target area corresponding to the microwave sensor, the brightness of the intelligent LED linear high-bay light in the corresponding target area is increased; The timing starts when no human movement is detected; If no human movement is detected after the timing starts, and the timing reaches the preset delay time, the brightness of the smart LED linear high bay light in the corresponding target area will be lowered to the standby brightness; When the smart LED linear high bay light corresponding to the target area is turned on, if it is detected that the ambient light brightness in the target area is greater than or equal to the preset light turn-on value, the smart LED linear high bay light corresponding to the target area is turned off; If the current control mode of the smart LED linear high bay light is the light sensing uncontrolled mode, when the microwave sensor detects that a human body is moving toward the target area corresponding to the microwave sensor, the smart LED linear high bay light corresponding to the target area is turned on and adjusted to the first preset brightness; The timing starts when no human movement is detected; If no human movement is detected after the timing starts, and the timing reaches the preset delay time, the brightness of the LED lights in the corresponding target area will be lowered to the standby brightness, and the standby timing will start; If no human movement is detected after the waiting time starts, and the waiting time reaches the waiting time, the smart LED linear high bay light in the corresponding target area will be turned off. The waiting time can be set as needed.

[0022] Example 2

[0023] This embodiment provides a smart LED linear high bay light control method, which mainly includes the following steps: like Figure 7 As shown, in this embodiment, the step S5: controlling the switch state and brightness of the smart LED linear high bay lights for lighting each target area according to the detection result of the microwave sensor on the movement of the human body also includes: S51: Get the current control mode of the smart LED linear high bay light; The smart LED linear high bay light of this embodiment can provide a variety of different control modes to suit different scenarios, and users can choose according to actual needs.

[0024] S52: According to the current control mode of the intelligent LED linear high bay light and the detection result of human movement by the microwave sensor, the switch state and brightness of the LED lights used for lighting in each target area are controlled.

[0025] like Figure 8 As shown, the control method specifically includes: S521: If the current control mode of the smart LED linear high bay light is the light sensing priority mode, obtain a preset light turn-on value; In the light priority mode, the microwave sensor senses the ambient light conditions and can reasonably control the lighting of the smart LED linear high bay light according to the environment. The preset light on value is a preset light brightness, which can be set according to actual needs. If the ambient light brightness is greater than the light on value, it means that the ambient brightness can meet user needs and the smart LED linear high bay light is not needed for lighting supplement. Otherwise, it means that the ambient light brightness is low and the smart LED linear high bay light is needed for lighting.

[0026] S522: Detecting the ambient light brightness in the target area; In a specific implementation, the brightness of the ambient light can be detected by a light sensor.

[0027] S523: If it is detected that the ambient light brightness in the target area is less than the preset light-on value, the smart LED linear high-bay light corresponding to the target detection area is turned on, and the brightness of the smart light is controlled to maintain at the standby brightness; The standby brightness is a lower brightness of the smart LED linear high bay light, which is lower than the brightness of the smart LED linear high bay light required for normal lighting in the target area. When no human movement is detected and the ambient light brightness is lower than the light-on value, the brightness of the smart LED linear high bay light is controlled at the standby brightness to save energy.

[0028] S524: When the microwave sensor detects that a human body is moving toward a target area corresponding to the microwave sensor, the brightness of the smart LED linear high bay light corresponding to the target area is increased; When someone is detected approaching the target area, the brightness of the smart LED linear high bay light can be adjusted to provide normal lighting for the user. This brightness is higher than the standby brightness of the smart LED linear high bay light.

[0029] S525: Start timing when no human body movement is detected; S526: If no human movement is detected after the timing starts, and the timing reaches the preset delay time, the brightness of the LED lights in the corresponding target area is lowered to the standby brightness.

[0030] If no human movement is detected after the preset delay time, the brightness of the smart LED linear high bay light can be lowered.

[0031] S527: When the LED light corresponding to the target area is turned on, if it is detected that the ambient light brightness in the target area is greater than or equal to the preset light turn-on value, the smart LED linear high bay light corresponding to the target area is turned off.

[0032] If the ambient brightness is sufficient to provide normal lighting, there is no need to turn on the smart LED linear high bay light, which can further reduce energy consumption.

[0033] like Fig. 9 As shown, S528: if the current control mode of the smart LED linear high bay light is the light sensing uncontrolled mode, when the microwave sensor detects that a human body is moving toward the target area corresponding to the microwave sensor, the smart LED linear high bay light corresponding to the target area is turned on and adjusted to the first preset brightness; The first preset brightness is the brightness that can provide normal lighting for the user. In the light-sensing uncontrolled mode, the control of the smart LED linear high-bay light does not take into account the brightness of the ambient light.

[0034] S529: Start timing when no human body movement is detected; S530: If no human movement is detected after the timing starts, and the timing time reaches the preset delay time, the brightness of the LED light in the corresponding target area is lowered to the waiting brightness, and the waiting timing starts. The waiting brightness is lower than the first preset brightness.

[0035] S531: If no human movement is detected after the waiting time starts, and the waiting time reaches the waiting time, the smart LED linear high bay light corresponding to the target area will be turned off.

[0036] In the control mode where the light sense is not controlled, if no human movement is detected, the brightness of the smart LED linear high bay light is maintained at the waiting brightness. If human movement is detected, the brightness of the LED light is adjusted to the first preset brightness and maintained for a period of time, that is, the aforementioned delay time. If no human movement is detected within a set period of time (waiting time) after adjusting to the waiting brightness, the smart LED linear high bay light can be turned off.

[0037] In this embodiment, the step S52: controlling the switch state and brightness of the smart LED linear high bay lights for lighting each target area according to the control mode of the current smart LED linear high bay light combined with the detection result of the human body movement by the microwave sensor also includes: When the scene mode is updated, obtaining the updated sensitivity of the microwave sensor corresponding to the new scene mode; The higher the sensitivity of the microwave sensor, the lower the probability of missed alarm, but the probability of false alarm will increase. Conversely, the lower the sensitivity of the microwave sensor, the greater the probability of missed alarm, but the probability of false alarm will decrease. Different scenarios have different requirements for missed alarms and false alarms. For example, in rest mode, the requirement for missed alarms can be appropriately lowered, and the requirement for false alarms can be increased. In this case, the sensitivity can be set to a lower sensitivity. In conference mode, the requirement for missed alarms can be appropriately increased, and the requirement for false alarms can be lowered. In this case, the sensitivity can be set to a higher sensitivity. This embodiment can realize setting different sensitivities for different scenarios. When the scene mode is switched from one scene mode to another, that is, after the scene mode is updated, the sensitivity of the microwave sensor is also updated.

[0038] The delay time is adjusted according to the difference between the update sensitivity and the initial sensitivity; After the sensitivity is updated, the time when the smart LED linear high bay light is turned on will change, thus affecting the energy consumption of the smart LED linear high bay light. In particular, after the sensitivity is increased, the smart LED linear high bay light may be turned on for a long time, resulting in increased energy consumption. In this step, the delay time can be adjusted according to the sensitivity adjustment. For example, after the sensitivity is increased, the delay time can be shortened to prevent the LED light from being turned on for too long due to false alarms. This can avoid missed alarms and prevent the smart LED linear high bay light from being turned on for a long time. In this case, the greater the difference between the updated sensitivity and the initial sensitivity, the shorter the adjusted delay time.

[0039] The current remaining energy consumption acquisition process includes acquiring the current remaining energy consumption according to the current total energy consumption standard and the current accumulated total energy consumption; The current total energy consumption standard can be set as needed. For example, when the total energy consumption reaches a certain value, the electricity price will exceed the user's tolerance. At this time, this value can be used as the current total energy consumption standard. The current cumulative total energy consumption is the cumulative amount of electricity used up to now. The difference between the current total energy consumption standard and the current cumulative total energy consumption is the current remaining energy consumption.

[0040] Determine the expected waiting time and the single-time turning-on energy consumption within the delay time when the LED lamp is turned on once according to the current remaining energy consumption; The expected single-time power consumption is the power consumed by the smart LED linear high bay light during the delay time and waiting time in the on state until it is finally turned off if no new human movement is detected after the smart LED linear high bay light is turned on.

[0041] The higher the residual energy consumption is, the higher the determined expected single start-up energy consumption is, and vice versa.

[0042] Obtain the power corresponding to the waiting brightness and the power corresponding to the first preset brightness; The power corresponding to the standby brightness is the power of the LED lamp when it is at the standby brightness, and the power corresponding to the first preset brightness is the power of the LED lamp when it is at the normal lighting brightness.

[0043] The waiting time is adjusted according to the adjustment amount of the delay time, the power corresponding to the waiting brightness, and the energy consumption of a single start; the energy consumption of a single start is equal to the sum of the energy consumption of the LED lamp during the waiting time and the energy consumption of the LED lamp during the delay time, while the energy consumption of the LED lamp during the waiting time is the product of the power of the LED lamp's waiting brightness and the waiting time, and the energy consumption of the LED lamp during the delay time is the product of the power of the LED lamp's first preset brightness and the delay time. Based on the above relationship, the waiting time that meets the energy consumption of a single start can be calculated.

[0044] Obtain the actual switching frequency and actual energy consumption of the LED lamp within the preset time period after adjustment; The length of the preset time can be set based on experience so as to more realistically reflect the actual switching frequency of the current LED, wherein the actual switching frequency is the ratio of the number of switches within the preset time period to the length of the preset time period.

[0045] The delay time is adjusted according to the current cumulative number of switching times of the LED lamp, the actual switching frequency of the LED lamp and the actual single-time power consumption; Since the number of times an LED lamp can be normally turned on and off is limited, and after the delay time is adjusted, the LED lamp may be frequently turned on and off, which has an adverse effect on the service life of the LED lamp. Therefore, this embodiment detects whether the change in the current remaining energy consumption reaches a preset change amount during the delay time. The preset change amount can be set empirically. If precise adjustment is required, the preset change amount can be set to a smaller value, otherwise it can be set to a larger value. This step updates the waiting time and delay time in a timely manner after the current remaining energy consumption has an expected change, so that the waiting time and delay time can be dynamically adjusted to adapt to the continuous change of energy consumption.

[0046] If otherwise keep the current waiting time and delay time unchanged; If yes, jump to the current remaining energy consumption acquisition process to update the waiting time and delay time; This embodiment dynamically updates the waiting time and the delay time according to the energy consumption of the LED lamp, so that after the sensitivity is adjusted according to the scene mode, the energy consumption requirement can still be met to the maximum extent.

[0047] In this embodiment, the delay time is adjusted according to the current cumulative number of switching times of the LED lamp, the actual switching frequency of the LED lamp, and the actual energy consumption, including: Obtain the expected range of the switching frequency according to the current cumulative number of switching times of the LED lamp; In this step, the total number of times the LED lamp can be normally switched on and off can be obtained first, and the remaining number of available switches can be obtained after deducting the current cumulative number of switches. Then, the expected range of the switching frequency is determined according to the remaining number of switches, wherein the upper and lower limits of the expected range of the switching frequency are positively correlated with the remaining number of switches, that is, the more the remaining number of switches, the greater the upper and lower limits of the expected range of the switching frequency, and vice versa. The difference between the upper and lower limits of the expected range can be set based on experience.

[0048] Determining whether the actual switching frequency of the LED lamp is within the expected range; If the actual switching frequency is within the expected range, gradually adjusting the delay time within the expected range according to the actual energy consumption until the actual single-on energy consumption is closest to the single-on energy consumption; In this step, the delay time can be gradually adjusted based on the current delay time. If the actual energy consumption is high, the delay time can be gradually shortened. After shortening the delay time once, the actual single-time power-on energy consumption after the delay time adjustment is calculated, and the actual switching frequency is detected to determine whether the actual switching frequency is within the expected range. If it exceeds, the extension time is adjusted back to the previous value and the adjustment is stopped.

[0049] If otherwise, the delay time is adjusted according to the difference between the actual switching frequency and the preset range.

[0050] If the actual switching frequency exceeds the preset range, the actual switching frequency is adjusted by shortening the adjustment delay time. The greater the difference between the actual switching frequency and the preset range, the shorter the adjusted delay time.

[0051] Due to the influence of noise in the environment, the detection of human movement may result in false alarms or missed alarms, which may cause the LED light to light up for too long and consume too much energy. It may also affect the lighting effect because the human movement is not detected when it actually exists. In this regard, in this embodiment, if the current control mode of the LED light is the light-sensing uncontrolled mode, the step S52: controlling the switch state and brightness of the LED lights used for lighting in each target area according to the current control mode of the LED light combined with the detection result of the human movement by the microwave sensor also includes: S5201: According to the sensitivity of microwave sensor , waiting time , Delay time Build an LED light switch Sub-objective function: ; is the false alarm rate caused by sensitivity; false alarm probability Indicates the false alarm probability of microwave sensors due to environmental noise and other factors, and sensitivity Closely related. You can set the sensitivity at different ambient noise levels while keeping the environment free of actual human activity. are different values.

[0052] Count the number of false alarms Nf at each sensitivity, , where Nt1 is the total number of tests.

[0053] in is the total monitoring time, is a coefficient related to the noise interference intensity. The higher the noise interference intensity, the The larger the value, the relationship between this value and the noise interference intensity can be calibrated through experiments under different interference intensities. The number of light switches at different sensitivities can be recorded within a fixed time (such as 1 hour). and the actual number of switches required , calculate the increase in the number of switches caused by false alarms , ; S5202: According to the LED light brightness , Switching times and sensitivity Building LED Light Energy Consumption Sub-objective function: ,in The actual time when the light is turned on, The ratio of energy consumption when the light is off to when the LED light is brightest. The coefficient of additional energy consumption caused by false alarms is calibrated through experiments under different false alarm rates.

[0054] Record the energy consumption at different sensitivities per unit time and ideal energy consumption , and then calculate the energy consumption increment caused by false alarm ,in ; in The power when the LED light is at its maximum brightness; It can be expressed by the ratio of the actual brightness of the LED light in the standby state to the maximum brightness.

[0055] S5203: According to sensitivity and the probability of underreporting Establishing detection accuracy Sub-function: ;Introduce controlled human movement in the target area and set standard movement modes (such as walking, waving, etc.). Set different sensitivities , count the number of missed reports Nm at each sensitivity, . Where Nt2 is the total number of tests.

[0056] S5204: Establishing Sensitivity , Switching times and LED lamp energy consumption The constraints are , , ; To prevent the minimum sensitivity of false negatives, To prevent false alarms, the highest sensitivity The maximum number of switching times allowed for the LED light, The maximum energy consumption of the system operation; S205: Establish a comprehensive objective function based on each sub-objective function and the weight of each sub-objective function: ; in is the weight coefficient corresponding to the number of times the LED light is switched on and off, is the weight coefficient corresponding to energy consumption, is the weight coefficient corresponding to the detection accuracy. If the current electricity consumption is at a peak or the electricity price is high Then the weight Adjust it higher, otherwise adjust it lower. The LED light can be set according to the scene. If it is in an important occasion such as a meeting, If the aisle light is not important, you can adjust it If you need to reduce the number of times the LED light switches on and off, you can Lower, otherwise you can Raise.

[0057] S206: Calculate the sensitivity by gradient descent algorithm according to the comprehensive objective function , waiting time , Delay time and wait brightness . Make the value of the objective comprehensive function as small as possible under the constraints.

[0058] After adopting the above scheme, the sensitivity can be adjusted dynamically by comprehensive , waiting time , Delay time and wait brightness These parameters enable better optimization of LED lamp energy consumption, detection accuracy and number of light switching times.

[0059] like Fig.10As shown, in this embodiment, multiple microwave sensors may be used to detect human body movement in a certain target area. In this regard, in this embodiment, at least one of the target areas corresponds to multiple microwave sensors, and the multiple microwave sensors include at least one first microwave sensor whose detection range completely covers the target area and at least two second microwave sensors whose detection range only covers a part of the target area. The detection ranges of the second microwave sensors are superimposed to completely cover the target area. Figure 8 As shown, the step S5: controlling the switch state and brightness of the LED lights for lighting each target area according to the detection result of the microwave sensor on the movement of the human body also includes: S501: Acquire detection results of human body movement by multiple microwave sensors corresponding to the target area; The detection results of the microwave sensor on the movement of the human body include two results: the human body moves toward the target area and the human body does not move toward the target area.

[0060] S502: Determine whether the detection results of the human body movement by the multiple microwave sensors corresponding to the target area are consistent; S503: If they are consistent, turn on the LED light corresponding to the target area or increase the brightness of the LED light corresponding to the target area; If the detection results of all microwave sensors are that there is a human body moving toward the target area or that there is no human body moving toward the target area, it indicates that the detection results are consistent. Otherwise, it indicates that the detection results are inconsistent.

[0061] S504: If they are inconsistent, obtaining the location information and operation information of the equipment within the preset range corresponding to the target area, as well as the location information, detection range information and sensitivity of each microwave sensor; S505: Determine the credibility coefficient of each microwave sensor according to the location information, detection range information, sensitivity, device location information and operation information of each microwave sensor; S506: Determine the credibility of the presence of human movement in the target area according to the credibility coefficients and detection results of each microwave sensor; The two detection results of human body moving toward the target area and human body not moving toward the target area are set to values ​​1 and -1 respectively. The credibility coefficient of each microwave sensor is multiplied by the value corresponding to its detection result to obtain the intermediate value corresponding to each microwave sensor. The credibility of human body movement in the target area can be obtained by adding up all the intermediate values. The above credibility indicates the possibility of human body movement in the target area.

[0062] S507 if the credibility is greater than a preset credibility, adjusting the operation waiting time and the delay adjustment time of the LED lamp used for lighting the target area according to the credibility; The operation waiting time refers to the time that the LED light needs to maintain its current state without any operation before turning on the LED light or adjusting the brightness of the LED light. The delay adjustment time refers to the time that needs to be waited before turning off the LED light or lowering the brightness of the LED light if no human movement is detected in the future.

[0063] Low credibility indicates that the possibility of actual human movement is small. In this case, the operation waiting time of the LED light can be increased to wait for further detection results, which can exclude the possibility of accidental movement of small objects in a short period of time. The delay adjustment time can also be shortened. If human movement is not detected again within a short delay adjustment time, the LED light can be turned off or the LED light brightness can be lowered, thereby reducing energy consumption caused by detection errors. High credibility indicates that the possibility of actual human movement is high. In this case, a shorter operation waiting time and a longer delay adjustment time can be appropriately adopted.

[0064] S508: delaying turning on the LED light or delaying increasing the brightness of the LED light according to the operation waiting time; When the reliability is higher than the preset reliability, the LED light is not operated immediately, but waits for a period of time (waiting time) before operating.

[0065] S509: Delay turning off the LED light or delay lowering the brightness of the LED light according to the delay adjustment time.

[0066] When no human movement is detected, a period of time (delay adjustment time) is waited. If no human movement is detected during this period of time, the LED light can be turned off or the brightness of the LED light can be lowered with a delay.

[0067] In this embodiment, the step S505: determining the credibility coefficient of each microwave sensor according to the location information, detection range information, sensitivity, location information and operation information of each microwave sensor includes: S5051: Obtaining the initial credibility coefficient corresponding to each microwave sensor at the current sensitivity; The initial credibility coefficient is the probability of the microwave sensor successfully detecting human movement in the absence of external interference signals. The probability of successful detection is different at different sensitivities, so the embodiment can set corresponding initial credibility coefficients for different sensitivities of the microwave sensor in advance.

[0068] S5052: Determine, according to the location information, detection range information and device location information of each microwave sensor, the microwave sensor that needs to be adjusted in credibility among the multiple microwave sensors as the target microwave sensor, and the remaining microwave sensors as non-target microwave sensors; The device of this embodiment is a device that generates interference signals for human body movement detection. If some devices are close to the detection range of the microwave sensor, it will affect the detection of the microwave sensor. Therefore, this step selects the microwave sensors that are close to the detection range of the microwave sensor or are within the detection range of the microwave sensor to adjust the credibility. The distance from the detection range that will affect the microwave sensor can be set based on experience.

[0069] S5053: Determine a credibility adjustment factor of each target microwave sensor according to the location information of the target microwave sensor, the location information of the device, and the operation information of the device; The closer the device is to the microwave sensor, the larger the credibility adjustment factor. In addition, the size of the adjustment factor is also related to the operating state of the device. For example, different sizes of adjustment factors correspond to different operating states of the air conditioner, such as cooling, heating, ventilation, and dehumidification. The larger the absolute value of the adjustment factor, the greater the change in the sensitivity of the microwave sensor. A positive adjustment factor increases credibility, while a negative adjustment factor reduces credibility.

[0070] S5054: Determine the credibility coefficient of the target microwave sensor according to the initial credibility coefficient and the credibility adjustment factor of the target microwave sensor; The adjusted credibility is equal to the unadjusted credibility plus the product of the unadjusted credibility and the credibility adjustment factor.

[0071] S5055: Using the initial credibility coefficient of each non-target microwave sensor as the credibility coefficient of the non-target microwave sensor.

[0072] The credibility of non-target microwave sensors remains unchanged at the initial credibility coefficient.

[0073] like Fig.11 As shown, in response to the situation of external signal interference, the method in this embodiment further includes: S31: Acquire the LED light illumination area as the target area; S32: judging whether the signal source of the interference signal is a dry signal source generated by a device in the access network according to the relevant information of the interference signal corresponding to the target area; In actual application scenarios, some devices that generate several signals are connected to the network. For example, air conditioners, electric curtains, automatic doors and other devices can be connected to networks such as the Internet of Things.

[0074] S33: If yes, obtaining the operating status of the device from the network; Devices connected to the network send their own operating status to the network, such as the on / off status, operating mode (cooling, ventilation, dehumidification) of the air conditioner, the on / off status, wind speed level of the fan, etc. With legal authorization, the operating status of these devices can be obtained from the network.

[0075] S34: acquiring an interference information filtering model corresponding to the operating state of the device according to the operating state of the device; A corresponding filtering model may be prepared in advance for each operating state. The filtering model is set for the operating state and is used to specifically filter interference signals generated when the device is in the corresponding operating state.

[0076] S35: filtering the interference information generated by the operation of the device according to the obtained interference information filtering model; For example, when it is obtained that the air conditioner in the current target area is in the cooling operation mode, a filtering model for the air conditioner operating in the cooling mode is obtained, the interference information is filtered using the model, and then the filtered signal is used to detect human body movement in the target area.

[0077] S36: Adjust the sensitivity of the microwave sensor according to the result of filtering the interference information of the target area.

[0078] If the filtering result is ideal, the sensitivity can be adjusted appropriately. If the filtering effect is not ideal, the sensitivity can be lowered appropriately. This can improve the accuracy of detection in the presence of noise.
