Description

Technical Field

[0001] The present invention relates to the field of home lighting technology, and in particular to a home lighting control system and method based on the Internet of Things. Background Art

[0002] Current home lighting control systems typically rely on motion sensors or light sensors to automatically turn lights on and off, making them suitable for everyday home use (e.g., automatically turning on lights when waking up or returning home at night). When the sensors detect human activity or a change in ambient light, the system automatically turns on the lights. However, this system has a drawback: it cannot distinguish between legitimate users and unauthorized intruders. Even after an intruder enters, the system still provides lighting, exposing the home's layout and allowing intruders to use the lighting system to conceal their presence, increasing the risk of theft or vandalism. Summary of the Invention

[0003] The purpose of the present invention is to provide a home lighting control system and method based on the Internet of Things. The technical problem to be solved is how to eliminate security risks such as the indiscriminate response of the lighting system, exposing the house layout, and concealing the whereabouts of intruders, and realize the deep integration and coordinated protection of lighting control and security functions.

[0004] The present invention is achieved through the following technical solutions:

[0005] A first aspect provides a home lighting control method based on the Internet of Things, comprising the following steps:

[0006] Upon receiving the door opening signal, the facial image of the person entering the room is collected and matched with the images of family members;

[0007] If the match is successful, the intruder is marked as a family member and the first lighting instruction is generated;

[0008] If the match fails, the facial image is uploaded to the user terminal;

[0009] When receiving a permission request fed back by the user terminal, the intruder is marked as a visitor and a first lighting instruction is generated; when receiving an alarm request fed back by the user terminal, the intruder is marked as an intruder and an alarm instruction is generated.

[0010] By capturing an intruder's facial image and matching it with images of family members, the system determines whether the intruder is a family member and distinguishes between legitimate users (i.e., family members and visitors) and intruders. If the match is successful, the intruder is marked as a family member. If the match fails, further confirmation is performed through the user terminal, allowing the lighting system to adopt different response strategies based on the intruder's identity, avoiding the potential safety hazards of indiscriminate lighting. If the facial image match fails, the system uploads the intruder's facial image to the user terminal and awaits user feedback. This not only increases the flexibility of lighting control but also provides users with the opportunity to remotely confirm the visitor's identity, enhancing the real-time and effectiveness of home security. If the lighting system confirms the intruder is an intruder, it quickly triggers an alarm to curb the intrusion and protect the family.

[0011] Furthermore, before receiving the door opening signal, the indoor area is obtained and the indoor area is divided into a plurality of lighting areas;

[0012] The aforementioned plurality of lighting areas include an entry lighting area, and a facial image of an entrant is collected in the entry lighting area.

[0013] Divide the indoor area into several lighting zones, and regional management reduces energy waste. Set entry lighting zones to identify intruders as soon as they enter the house, and trigger an alarm immediately when potential intrusion is detected.

[0014] Furthermore, it detects whether there are people in the indoor area;

[0015] If there are people in the above indoor area, the number of people in the indoor area is recorded to obtain the number of people in the room;

[0016] Obtain all occupant marks in the indoor area to obtain an occupant mark set;

[0017] When the set of occupant markers is one or more of family members and visitors, detecting whether there is a person in the lighting area; when there is a person in the lighting area, generating a second lighting instruction, and turning on the lighting device in the corresponding lighting area according to the second lighting instruction; when there is no person in the lighting area, generating a standby instruction;

[0018] When an intruder exists in the above occupant tag set, an alarm instruction is generated;

[0019] If there is no one in the indoor area, a standby command is generated.

[0020] Lighting is provided to those in the room, combining the identity and location information of those in the room. By recording the number of people in the indoor area and obtaining the identity tags of those in the room (family members, visitors, or intruders), the current security status of the indoor environment is determined. If an intruder is present, lighting is disabled to prevent the intruder from learning the layout of the house or the whereabouts of other occupants. When the intruder tags are concentrated and an alarm is generated, triggering security measures. This effectively improves the real-time and effectiveness of home security and provides more comprehensive safety protection for family members. Lighting is activated based on whether there is a legitimate user in the lighting area, ensuring the lighting needs of those in the room while avoiding unnecessary energy waste and potential safety risks. If there are no occupants in the lighting area or the indoor area is unoccupied, the system generates a standby command, turning off unnecessary lighting and reducing household energy consumption.

[0021] Furthermore, when there is a person in the lighting area, and the person in the room is marked as one or more of a family member and a visitor, detecting whether the person in the room leaves the lighting area;

[0022] When the above-mentioned person in the room leaves the lighting area, a light-off instruction is generated;

[0023] Call the preset light-off delay and execute the light-off command after the light-off delay.

[0024] By continuously detecting whether occupants have left the illuminated area, the system detects changes in lighting needs in real time. When a occupant leaves, a lights-off command is generated, but not immediately executed. Instead, a preset lights-off delay is invoked. This ensures that lighting is promptly turned off after the occupant leaves, while also avoiding the inconvenience and energy waste associated with frequent lights on and off during brief absences (e.g., to retrieve items or have a quick conversation). The lights-off delay prevents the lighting from shutting off immediately due to a occupant's brief absence, reducing unnecessary energy consumption. Furthermore, if the occupant leaves and does not return, the lighting automatically turns off after the delay expires, further enhancing energy savings.

[0025] A second aspect provides a home lighting control system based on the Internet of Things, wherein the home lighting control system adopts the above-mentioned home lighting control method; the home lighting control system comprises:

[0026] A collection device, the collection device is used to receive the door opening signal and collect the facial image of the person entering the room;

[0027] a processing device connected to the acquisition device, configured to receive a facial image and match the facial image with images of family members;

[0028] If the match is successful, the intruder is marked as a family member and the first lighting instruction is generated;

[0029] If the match fails, the above face image is sent;

[0030] a lighting device, the lighting device being connected to the processing device, and the lighting device being configured to receive a first lighting instruction and turn on the lighting device according to the first lighting instruction;

[0031] A cloud server and a user terminal, wherein the cloud server is connected to the user terminal and the processing device, and the user terminal and the processing device exchange information through the cloud server;

[0032] The user terminal is used to send permission requests and alarm requests;

[0033] When the processing device receives a permission request from the user terminal, it marks the intruder as a visitor and generates a first lighting instruction; when the processing device receives an alarm request from the user terminal, it marks the intruder as an intruder and generates an alarm instruction.

[0034] Furthermore, the processing device is used to obtain an indoor area before receiving a door opening signal, and divide the indoor area into a plurality of lighting areas;

[0035] The aforementioned lighting areas include an entry lighting area, and the facial image of the entrant is collected by the collection device in the entry lighting area.

[0036] Furthermore, each of the above-mentioned lighting areas is provided with a sensor, and the above-mentioned sensor is connected to the processing device; the above-mentioned sensor is used to detect whether there is a person in the lighting area.

[0037] Furthermore, the acquisition device is further configured to acquire indoor images and transmit the indoor images to a processing device, which performs the following operations:

[0038] Detect whether there is anyone in the above indoor area;

[0039] If there are people in the above indoor area, the number of people in the indoor area is recorded to obtain the number of people in the room;

[0040] Obtain all occupant marks in the indoor area to obtain an occupant mark set;

[0041] When the set of occupant markers contains one or more of family members and visitors, a sensor detects whether there is a person in the lighting area; when there is a person in the lighting area, a second lighting instruction is generated, and the lighting device in the corresponding lighting area is turned on according to the second lighting instruction; when there is no one in the lighting area, a standby instruction is generated;

[0042] When an intruder exists in the above occupant tag set, an alarm instruction is generated;

[0043] If there is no one in the indoor area, a standby command is generated.

[0044] Furthermore, the processing device is further configured to perform the following operations:

[0045] When there is a person in the lighting area, and the person is marked as one or more of a family member and a visitor, the sensor detects whether the person leaves the lighting area;

[0046] When the above-mentioned person in the room leaves the lighting area, a light-off instruction is generated;

[0047] Call the preset light-off delay and execute the light-off command after delaying the above light-off delay.

[0048] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0049] By capturing an intruder's facial image and matching it with images of family members, the system determines whether the intruder is a family member and distinguishes between legitimate users (i.e., family members and visitors) and intruders. If the match is successful, the intruder is marked as a family member. If the match fails, further confirmation is performed through the user terminal, allowing the lighting system to adopt different response strategies based on the intruder's identity, avoiding the potential safety hazards of indiscriminate lighting. If the facial image match fails, the system uploads the intruder's facial image to the user terminal and awaits user feedback. This not only increases the flexibility of lighting control but also provides users with the opportunity to remotely confirm the visitor's identity, enhancing the real-time and effectiveness of home security. If the lighting system confirms the intruder is an intruder, it quickly triggers an alarm to curb the intrusion and protect the family. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0056] First embodiment:

[0057] Combine Figure 1 , a home lighting control method based on the Internet of Things, comprising the following steps:

[0058] Upon receiving the door opening signal, the facial image of the person entering the room is collected and matched with the images of family members;

[0059] If the match is successful, the intruder is marked as a family member and a first lighting instruction is generated. The first lighting instruction adjusts the lighting system to standby mode and controls the lighting equipment in the entry lighting area. When no one is in the room, the lighting system is adjusted to off mode.

[0060] If the match fails, the facial image is uploaded to the user terminal;

[0061] When receiving a permission request fed back by the user terminal, the intruder is marked as a visitor and a first lighting instruction is generated; when receiving an alarm request fed back by the user terminal, the intruder is marked as an intruder and an alarm instruction is generated.

[0062] By capturing an intruder's facial image and matching it with images of family members, the system determines whether the intruder is a family member and distinguishes between legitimate users (i.e., family members and visitors) and intruders. If the match is successful, the intruder is marked as a family member. If the match fails, further confirmation is performed through the user terminal, allowing the lighting system to adopt different response strategies based on the intruder's identity, avoiding the potential safety hazards of indiscriminate lighting. If the facial image match fails, the system uploads the intruder's facial image to the user terminal and awaits user feedback. This not only increases the flexibility of lighting control but also provides users with the opportunity to remotely confirm the visitor's identity, enhancing the real-time and effectiveness of home security. If the lighting system confirms the intruder is an intruder, it quickly triggers an alarm to curb the intrusion and protect the family.

[0063] The lighting system is usually used in the indoor environment of a home. Its purpose is to improve residential safety in legal scenarios. Considering user privacy, even if the facial images it collects cannot be used for identity recognition, they will only be fed back to specific users through the user terminal, thereby ensuring a reasonable browsing range of the facial images and avoiding the risk of privacy leakage.

[0064] Second embodiment:

[0065] Based on the first embodiment, before receiving the door opening signal, the indoor area is obtained and the indoor area is divided into a plurality of lighting areas;

[0066] The aforementioned lighting areas include indoor lighting areas and living lighting areas. Facial images of entrants are collected in the indoor lighting areas. These areas can be areas directly connected to the outdoors, such as doors and windows. Living lighting areas can be areas like living rooms, bedrooms, and kitchens.

[0067] Divide the indoor area into several lighting zones, and regional management reduces energy waste. Set entry lighting zones to identify intruders as soon as they enter the house, and trigger an alarm immediately when potential intrusion is detected.

[0068] Third embodiment:

[0069] Based on the second embodiment, detecting whether there is someone in the indoor area;

[0070] If there are people in the indoor area, the number of people in the indoor area is recorded to obtain the number of people in the room. When the number of people in the room exceeds twice the number of intruders, the lighting equipment can be turned on for the legitimate users. When the number of people in the room is less than twice the number of intruders, the lighting equipment will not be turned on for the legitimate users and intruders.

[0071] Obtain all occupant marks in the indoor area to obtain an occupant mark set;

[0072] When the above-mentioned set of occupant mark contains one or more of family members and visitors, detecting whether there is anyone in the above-mentioned lighting area (including the entrance lighting area and the living lighting area); when there is someone in the above-mentioned lighting area, generating a second lighting instruction, and turning on the lighting equipment in the corresponding lighting area according to the second lighting instruction; when there is no one in the above-mentioned lighting area, generating a standby instruction;

[0073] When an intruder exists in the above occupant tag set, an alarm instruction is generated;

[0074] If there is no one in the indoor area, a standby command is generated.

[0075] Lighting is provided to those in the room, combining the identity and location information of those in the room. By recording the number of people in the indoor area and obtaining the identity tags of those in the room (family members, visitors, or intruders), the current security status of the indoor environment is determined. If an intruder is present, lighting is disabled to prevent the intruder from learning the layout of the house or the whereabouts of other occupants. When the intruder tags are concentrated and an alarm is generated, triggering security measures. This effectively improves the real-time and effectiveness of home security and provides more comprehensive safety protection for family members. Lighting is activated based on whether there is a legitimate user in the lighting area, ensuring the lighting needs of those in the room while avoiding unnecessary energy waste and potential safety risks. If there are no occupants in the lighting area or the indoor area is unoccupied, the system generates a standby command, turning off unnecessary lighting and reducing household energy consumption.

[0076] In a specific embodiment, when there is a person in the lighting area and the person is marked as one or more of a family member and a visitor, detecting whether the person has left the lighting area;

[0077] When the above-mentioned person in the room leaves the lighting area, a light-off instruction is generated;

[0078] Call the preset light-off delay and execute the light-off command after the light-off delay.

[0079] By continuously detecting whether occupants have left the illuminated area, the system detects changes in lighting needs in real time. When a occupant leaves, a lights-off command is generated, but not immediately executed. Instead, a preset lights-off delay is invoked. This ensures that lighting is promptly turned off after the occupant leaves, while also avoiding the inconvenience and energy waste associated with frequent lights on and off during brief absences (e.g., to retrieve items or have a quick conversation). The lights-off delay prevents the lighting from shutting off immediately due to a occupant's brief absence, reducing unnecessary energy consumption. Furthermore, if the occupant leaves and does not return, the lighting automatically turns off after the delay expires, further enhancing energy savings.
