[0005] For example, due to the large coverage of wireless signals, if the user's handheld electronic device is outdoors and is still within the coverage of the wireless signal, the smart lighting device will also remain turned on, resulting in a waste of power resources. In addition, when the user is indoors and the electronic device fails to connect to the wireless short-range communication network due to a fault, the smart lighting device cannot be successfully turned on and still needs to be turned on manually, which runs counter to the intelligent control means in the above-mentioned prior art.

BRIEF DESCRIPTION OF THE DRAWINGS
[0051] The present invention will be further described below in conjunction with the accompanying drawings.
[0052] Figure 1 It is a flow chart of the present invention. DETAILED DESCRIPTION
[0053] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0054] like Figure 1 As shown, a system for intelligently adjusting the color temperature of indoor lighting described in an embodiment of the present invention includes a monitoring module, including a light sensing unit and a motion sensor; the light sensing unit includes a photoresistor sensor for monitoring the indoor brightness value; the motion sensor is used to monitor the activities occurring in the room and determine whether there are people; and also includes an analysis module, which receives the brightness value collected by the light sensing unit and compares it with the brightness threshold, and when the indoor brightness value is lower than the brightness threshold, outputs a first instruction to the control module; after outputting the first instruction, the analysis module determines whether there are people in the room based on the information collected by the motion sensor: when there are people in the room, outputs a second instruction to the control module; the control module is used to turn on and off the lighting device, and when the control module receives the first instruction and the second instruction, the lighting device is turned on; when the control module only receives the first instruction or the second instruction, the lighting device is kept off.
[0055] Although the prior art discloses the basic logic of controlling the on and off of lighting equipment, there are still some problems in judging whether there is someone indoors based on detecting whether the indoor wireless short-range communication network is connected:
[0056] For example, due to the large coverage of wireless signals, if the user's handheld electronic device is outdoors and is still within the coverage of the wireless signal, the smart lighting device will also remain turned on, resulting in a waste of power resources. In addition, when the user is indoors and the electronic device fails to connect to the wireless short-range communication network due to a fault, the smart lighting device cannot be successfully turned on and still needs to be turned on manually, which runs counter to the intelligent control means in the above-mentioned prior art.
[0057] Based on the above, as an embodiment of the present invention, a light sensing unit and a motion sensor are used for monitoring, and the indoor brightness value is judged by the light sensing unit. When the brightness value is lower than the brightness threshold, the lighting device should be turned on to increase the brightness value, that is, the first instruction is output to the control module. However, if there is no one in the room, directly turning on the lighting device is bound to cause a waste of power resources, so it is also necessary to verify through the monitoring information of the motion sensor; when there is someone in the room, it can be detected by the motion sensor, and then the second instruction is output to the control module; when the control module receives the first instruction and the second instruction, the lighting device will be turned on; otherwise, the lighting device will not be turned on;
[0058] It is worth noting that the motion sensor uses infrared, microwave or ultrasonic technology to detect human motion; and based on the premise of avoiding wasting power resources, the motion sensor sends a second command at regular intervals when someone is indoors for verification, thereby ensuring that the smart lighting device remains on; the brightness threshold is a manually set brightness value;
[0059] The first instruction and the second instruction are both sent at regular intervals. If the intelligent lighting device is in the on state, and the control module only receives the first instruction at a certain moment, the intelligent lighting device is controlled to be turned off.
[0060] Preferably, the analysis module further includes a calculation unit for calculating an activity value corresponding to the activity situation; the activity value is calculated based on the thermal radiation value and air vibration value around the human body collected by the motion sensor; according to the formula:
[0061]
[0062] Among them, A represents the activity value; T represents the thermal radiation value; V represents the air vibration value; wT represents the weight corresponding to the thermal radiation value, and wV represents the weight corresponding to the air vibration value.
[0063] Based on the above, nowadays, with the development of LED technology, lighting and color temperature adjustment have become more convenient and diversified; traditional color temperature adjustment methods usually rely on a combination of light sources with different color temperatures. In a simple lighting device, it may contain LED lamp beads with different color temperatures, such as warm light (3000K) and cold light (6500K) LEDs. By adjusting the ratio of these two light sources, a neutral color temperature (4000K) between the two can be mixed.
[0064] With further improvements in technology, more precise color temperature control can be achieved by adjusting the current ratio of the LED driver power supply. This method is based on the following principle: by changing the current passing through the LED, the color temperature and brightness of the light it emits can be fine-tuned. This not only achieves continuous adjustment of the color temperature, but also maintains the overall brightness of the lighting equipment unchanged, avoiding the lighting effect being affected by adjusting the color temperature.
[0065] Although continuous adjustment of color temperature can be achieved more easily and accurately, in the prior art, the control of color temperature still mainly relies on manual adjustment, whether it is adjusted by a mobile terminal or a switch, human intervention is required;
[0066] In one embodiment of the present invention, since a motion sensor is used to determine whether there is anyone indoors, the thermal radiation value and air vibration value of the human body during activity are obtained based on the motion sensor; and the activity value A of the human body activity is calculated using a formula; the different states of indoor users, such as resting state, normal state and exercise state, are distinguished by the calculated activity value A; and the color temperature of the intelligent lighting device is automatically adjusted. Normally, the lighting device should maintain a low color temperature in the rest state, while the color temperature needs to be increased in the exercise state to stimulate the user; based on the monitoring of the user's exercise state and the calculation of the activity value, the user's activity behavior can be accurately grasped, and then instructions can be output to control the intelligent lighting device to switch the color temperature, so that the user is in a suitable color temperature environment when performing different types of activities.
[0067] Preferably, the analysis module is also used to output instructions for adjusting the color temperature of the lighting device according to the active value; the instructions for adjusting the color temperature of the lighting device include a third instruction and a fourth instruction; the third instruction is used to adjust the lighting device to a high color temperature state; and the fourth instruction is used to adjust the lighting device to a low color temperature state.
[0068] Based on the above, after calculating the user's activity value A, the user's status is distinguished according to a predetermined threshold, and different control instructions are output to the control module to achieve the effect of adjusting the color temperature of the smart lighting device; specifically, the instructions for adjusting the color temperature of the smart lighting device include a third instruction and a fourth instruction. The default smart lighting device is in a medium color temperature state when turned on, corresponding to the user's normal state; the third instruction is used to adjust the smart lighting device to a high color temperature state, and the fourth instruction is used to adjust the smart lighting device to a low color temperature state.
[0069] Preferably, the method for outputting an instruction for adjusting the color temperature of a lighting device according to the active value is:
[0070] Get the activity threshold interval that matches the user's normal activities;
[0071] When the active value is within the active threshold range, no instruction to adjust the color temperature is output, and the current color temperature is maintained;
[0072] When the active value is greater than the upper limit of the active threshold range, a third instruction is output to adjust the lighting device to a high color temperature state;
[0073] When the activity value is less than the lower limit of the activity threshold range, a fourth instruction is output to adjust the lighting device to a low color temperature state.
[0074] Based on the above, as an embodiment of the present invention, to distinguish the state of the user, first, according to the user's historical activity information, an active threshold interval that meets the user's normal activities is obtained. Within the range of the active threshold interval, it means that the user is in a normal state. Then, when the user switches states, such as resting or exercising, the active value A will change, thereby updating the active value A. If the active value A at the current moment is updated, after the analysis module compares it with the active threshold interval, the active value is greater than the upper limit of the interval, then the third instruction is output, as mentioned above, to control the intelligent lighting device to adjust from the medium color temperature state to the high color temperature state. When the active value is less than the lower limit of the interval, the fourth instruction is output to control the lighting device to adjust from the medium color temperature state to the low color temperature state. By comparing the active value with the active threshold interval, the automatic adjustment of the color temperature of the intelligent lighting device is realized by relying on the analysis module and the control module.
[0075] It is worth noting that the motion sensor sends the user's status information regularly, so the activity value A can also be updated regularly.
[0076] Preferably, the control module is further used to receive a third instruction and a fourth instruction output by the analysis module; the control module adjusts the color temperature of the lighting device based on the first instruction, the second instruction and the third instruction or the fourth instruction.
[0077] As an embodiment of the present invention, the control module receives the third instruction or the fourth instruction on the premise that it has received the first instruction and the second instruction, that is, the third instruction or the fourth instruction will not be sent to the control module separately, that is, only after the control module controls the smart lighting device to turn on, the analysis module can output the third instruction or the fourth instruction, and the control module can receive the third instruction or the fourth instruction, and the third instruction and the fourth instruction cannot be sent and received at the same time.
[0078] Preferably, it also includes a mobile terminal; the mobile terminal is used to display the status information of the current lighting device, including the on / off status and the brightness status;
[0079] The control module is also used to receive a fifth instruction issued by the mobile terminal, and the control module performs manual adjustment of the lighting device based on the fifth instruction.
[0080] As an embodiment of the present invention, the status information of the current intelligent lighting device is displayed through the mobile terminal, and the information that can be consulted includes the on / off status and brightness status of the intelligent lighting device, wherein the brightness status includes: medium color temperature, high color temperature and low color temperature;
[0081] The fifth instruction can also be sent manually using the mobile terminal. Based on the fifth instruction, the control module can control and adjust the intelligent lighting device, including turning it on and off, adjusting the color temperature, etc.
[0082] Preferably, a feedback module is further included, and the light sensing unit is further used to monitor the status information of the lighting device after being adjusted by the control module;
[0083] The light sensing unit sends the state information of the lighting device adjusted by the control module to the feedback module;
[0084] The feedback module compares the adjusted state information of the lighting device with the pre-adjusted state information, and outputs an alarm signal to the mobile terminal when the adjusted state information of the lighting device does not match the pre-adjusted state information.
[0085] As an embodiment of the present invention, in addition to automatic and manual adjustment of the intelligent lighting device, after the control module controls the intelligent lighting device according to the instruction, it is also necessary to feedback the status information of the intelligent lighting device. After an action of the control module is completed, the light sensing unit is used to monitor the brightness value and color temperature of the room. If it is inconsistent with the pre-adjustment information corresponding to the control instruction, an alarm signal is output, indicating that the intelligent lighting device may have a fault;
[0086] Failure types include:
[0087] Overload
[0088] Cause: The equipment is overloaded, resulting in excessive current.
[0089] Solution: Reduce the load and adjust the rated capacity.
[0090] Symptoms: Equipment overheating, protective fuse blown, etc.

[0098] Symptoms: Some devices fail to work due to circuit breaker, and lights become dim or not at all.

[0101] Solution: Check and repair line insulation and deal with leakage points.
[0102] Symptoms: Current leakage and unreasonable increase in power may cause fire.
[0103] Power supply abnormality
[0104] Cause: Grid voltage fluctuation, power supply system problem.
[0105] Solution: Adjust the power supply system and add voltage regulating equipment.
[0106] Symptoms: The equipment is difficult to start, the voltage is too high or too low.
[0107] Preferably, it also includes a router, and the mobile terminal is connected to the router through short-range wireless communication technology; after detecting any mobile terminal connection, the router outputs a second instruction to the control module.
[0108] As an embodiment of the present invention, the prior art uses a mobile terminal to connect to a short-range wireless communication network to determine whether there is someone indoors. On this basis, the present application also uses a mobile terminal to make an additional judgment. However, the difference is that the connection between the mobile terminal and the wireless communication network is used in the present application only as a manifestation of determining that the user is about to return to the residence. Specifically, when the user is on the way back to the residence, the mobile terminal can be connected to the router. After verification by the router, the router outputs a second instruction, which serves as the basis for the control module to turn on the smart lighting device.
[0109] Preferably, the method in which the router detects any mobile terminal connection and outputs the second instruction to the control module is:
[0110] Based on the connection between router and mobile terminal;
[0111] According to the formula:
[0112]
[0113] Where K represents the signal value, The distance from the router The signal value of the mobile terminal at the router; n is the interference parameter; d represents the distance between the mobile terminal and the router;
[0114] According to the formula, multiple signal values Ki of the mobile terminal in continuous time are calculated in units of minutes, i=1,2,3....m;
[0115] Arrange multiple signal values Ki in chronological order to form a signal value sequence U:
[0116] When the signal value sequence U shows an overall upward trend, a second instruction is output to the control module;
[0117] When the signal value sequence U shows an overall downward trend, the second instruction is not output;
[0118] When the overall trend of the signal to sequence U remains unchanged, the second instruction is not output.
[0119] Further, as an embodiment of the present invention, when determining whether to turn on the smart lighting device by connecting the mobile terminal to the router, there are many possibilities for the user, including that the user is indeed on the way back to the residence, the user is staying near the residence, the user is leaving the residence, etc.;
[0120] Based on the above, the signal value of the user's mobile terminal connected to the router detected by the router is used to further distinguish the user status. For example, if the user is indeed on the way back to the residence, since the router has a large coverage area, when the user enters the coverage area, the mobile terminal can be verified and connected to the router. As time goes by, the user gradually approaches the residence, so the signal value will gradually increase; when the user stays near the residence, assuming that the user is within the coverage area of the router, the router can also monitor the signal value, and the signal value should remain unchanged over time; in addition, if the user leaves the residence, the signal value should gradually decrease over time until the connection is disconnected;
[0121] Therefore, by calculating the signal value after the mobile terminal is connected to the router, the user's status over a period of time can be roughly estimated, so as to use the connection between the mobile terminal and the router to control the smart lighting device to turn on in advance through the control module;
[0122] in, The distance from the router When using this formula to calculate the signal value after the mobile terminal is connected to the router, the signal value of the mobile terminal is measured multiple times at a fixed position in advance, and then the signal value and distance are substituted into the formula for multiple training to determine the final and corresponding ; and determining the interference parameter n.
[0123] A method for intelligently adjusting the color temperature of indoor lighting, comprising the following steps:
[0124] S1: Collect the indoor brightness value and determine whether there is anyone in the room;
[0125] S2: When the indoor brightness value is lower than the brightness threshold, the first instruction is output; when there is someone in the room, the second instruction is output;
[0126] S3: Based on the first instruction and the second instruction, the intelligent lighting device is turned on;
[0127] S4: Collect and calculate the activity value of indoor users;
[0128] S5: outputting a third instruction or a fourth instruction based on the indoor user activity value;
[0129] S6: When the third instruction is output, the intelligent lighting device is adjusted to a high color temperature state; when the fourth instruction is output, the intelligent lighting device is adjusted to a low color temperature state.
[0130] Working principle: The indoor brightness value is detected by the photosensitive unit. When the indoor brightness value is lower than the brightness threshold, the first instruction is output, and the monitoring information of the motion sensor is analyzed at the same time. When there is someone in the room, the second instruction is output, and the intelligent lighting device is turned on under the control of the control module. Based on the premise of avoiding waste of power resources, the motion sensor sends the second instruction regularly when there is someone in the room for verification, thereby ensuring that the intelligent lighting device remains on; the running status of the indoor user is monitored by the motion sensor, and the activity value of the indoor user is calculated. When the user's activity value is greater than the upper limit of the active threshold interval, the third instruction is output to adjust the intelligent lighting device to a high color temperature state. When the user's activity value is less than the lower limit of the active threshold interval, the fourth instruction is output to adjust the intelligent lighting device to a low color temperature state. Based on the monitoring of the user's motion status and the calculation of the activity value, the user's activity behavior can be accurately grasped, and then the instruction is output to control the intelligent lighting device to switch the color temperature, so that the user is in a suitable color temperature environment when performing different types of activities.
