[0018] An embodiment of the present application discloses a method and a system for home security.

[0020] It should be noted that the above modules are only the basic steps of this embodiment. In the specific implementation process, without affecting the overall implementation effect, some steps can be appropriately added, reduced or modified.

[0021] The steps of generating a three-dimensional house model according to the home house data, determining the optimal installation points of the security devices according to the three-dimensional house model and the security device parameters, and performing visual debugging are specifically as follows: Extract the house size data in the home house data and construct a three-dimensional house model according to the house size data; According to the security device parameters, obtain the working mode of the security device, and determine the initial working position of the security device according to the working mode; Based on the initial working position, simulate the installation of the device in the three-dimensional house model and obtain the working range of the security device; Perform visual position debugging on the security device according to the working range, determine the optimal installation points where the security device can exert the maximum utility, and install the security device in the house according to the optimal installation points.

[0022] In operation, taking a 120-square-meter residence with three bedrooms and one living room as an example, the house size data in the family house data of this house is extracted, including the length, width, and height parameters of each room (master bedroom: 4m × 5m × 2.8m, secondary bedroom: 3.5m × 4m × 2.8m, living room: 6m × 4.5m × 3m). According to these size data, a three-dimensional model of the house is constructed, and the positions of doors and windows in the model are marked as hollow frames (for example, the size of the master bedroom window is 1.8m × 1.5m, and the size of the entrance door is 0.9m × 2.1m). According to the security device parameters, the working mode of the intelligent camera is obtained as horizontal rotation monitoring at 120 degrees, and the initial working positions are determined as the two corner points of the diagonal of the living room (coordinate point A(0,0,2.5m) and coordinate point B(6,4.5,2.5m)). After simulating the installation in the three-dimensional model, it is found that the working range of the camera at coordinate point A can cover 80% of the living room area, but there is a blind area blocked by the kitchen, and there is a balcony reflection interference at coordinate point B. After visual debugging, coordinate point A is adjusted to (0.5,0.5,2.6m) and a 30-degree downward angle is added, so that the working range covers the entire living room area and the kitchen entrance. Finally, this point is determined as the optimal installation point.

[0023] According to the security device parameters, obtain the power supply requirements of the security device, and the steps for constructing a backup power supply and a photovoltaic power generation device according to the power supply requirements are as follows: Based on the security device parameters, obtain the power supply requirements of the security device, connect the security device to the household electricity according to the power supply requirements, and at the same time reserve an emergency power supply interface; Construct a backup power supply according to the power supply requirements, collect the power supply size of the backup power supply, and obtain the installation position of the backup power supply according to the power supply size and the family house data; According to the family house data, obtain the installation conditions for photovoltaic power generation, and install photovoltaic power generation equipment according to the installation conditions for photovoltaic power generation; Electrically connect the photovoltaic power generation equipment to the backup power supply, and electrically connect the backup power supply to the emergency power supply interface.

[0024] In operation, taking a 120-square-meter residence with three bedrooms and one living room as an example, the total power consumption is calculated to be 85 W based on the equipment parameters (where two smart cameras total 30 W, three door and window sensors total 15 W, one smoke alarm is 5 W, and the main control device is 35 W). An emergency interface (output 220 V / 10 A) is reserved in the distribution box, and a lithium iron phosphate backup power supply (capacity 2000 Wh, size 400 mm × 300 mm × 200 mm) is installed. The backup power supply is installed on the wall of the storage room according to the floor plan of the house (coordinate point C(1.2, 3.8, 0.6 m)). It is detected that the outer wall of the south-facing balcony meets the conditions for photovoltaic installation (sunshine duration 6 hours per day, no obstruction), and three 450-W monocrystalline photovoltaic panels (size 1765 mm × 992 mm × 35 mm) are installed. The output end (DC 48 V) of the photovoltaic equipment is connected to the input end of the backup power supply through a 6-square copper core cable, and the output end of the backup power supply is connected to the emergency interface through a converter. The test shows that in the case of a power outage, the backup power supply can maintain the operation of the security system for 23 hours.

[0025] According to the security equipment parameters, obtain multiple different security communication protocols, and perform protocol conversion on the security communication protocols according to the protocol data processing center to generate a target communication protocol with a unified format. The specific steps are as follows: Based on the security equipment parameters, extract the security communication protocols of security equipment of different brands in the security equipment parameters; Based on different security communication protocols, extract the protocol features in each security communication protocol, and fuse multiple protocol features to generate a combined protocol feature; Based on the combined protocol feature, amplify the combined protocol feature to generate a target protocol feature; Based on the target protocol feature, perform protocol conversion on the security communication protocol to generate a target communication protocol with a unified format.

[0026] In operation, taking a 120-square-meter residence with three bedrooms and one living room as an example, a certain family mixes A-brand cameras (using the Modbus protocol) and B-brand sensors (using the Zigbee3.0 protocol). The protocol data processing center extracts the register address features of the Modbus protocol (4-byte data frame, function code 03) and the mesh network features of the Zigbee protocol (16-bit short address, CSMA-CA collision detection). The two protocol features are fused to generate a joint protocol feature, including a data length field (0x0004), a verification method (CRC16), and a device identification field (8-bit manufacturer code + 16-bit device ID). The check bit is extended to 32 bits through feature amplification to generate a target protocol feature (data header 0xAA55, data body containing 32-bit timestamp + 128-bit encrypted payload). When converting the protocol, the 03 function code of the A-brand data frame is converted into the action code 0x01 of the target protocol, and the short address of Zigbee is converted into the position code 0x1F03 of the target protocol, and finally a data packet in a unified format is generated (total length 256 bytes, including 16-byte packet header and 240-byte payload).

[0027] The steps of sending the security data stream to the protocol data processing center, and the protocol data processing center performing protocol conversion on the security data stream according to the target communication protocol to generate a unified data stream are as follows: Send the security data stream to the protocol data processing center, and the protocol data processing center splits the security data stream to obtain content data and a security communication protocol; Based on the target communication protocol, the protocol processing center replaces the security communication protocol; Integrate the target communication protocol with the content data to generate a unified data stream.

[0028] In operation, taking a 120-square-meter residence with three bedrooms and one living room as an example, when the living room camera detects a moving object, an original data stream is generated (including an H.264 video stream of 30 frames per second and a TCP / IP protocol header). The protocol data processing center splits the data stream into content data (video payload) and protocol data (source IP 192.168.1.100, target port 554). Replace the RTSP protocol with the target communication protocol, and the new protocol header includes a device type code 0x02 (video device) and a timestamp 2023-08-20T14:30:00.000Z. The content data remains in the original H.264 encoding unchanged. The length of the re-encapsulated unified data stream changes from 1500 bytes to 1632 bytes, with a 32-byte target protocol header added. When this data stream is forwarded to the intelligent door lock device, the door lock recognizes it as video data according to the device type code 0x02 in the protocol header and automatically calls the video decoding module for processing.

[0029] Steps for obtaining the user's daily routine habits, obtaining a false alarm scenario set based on the user's daily routine habits, and filtering the unified data stream according to the false alarm scenario set to obtain the target data stream are as follows: Obtain the user's daily routine habits, divide the user's daily routine habits into scenarios, and obtain a set of user behavior scenarios; Conduct a misidentification assessment on the set of user behavior scenarios to obtain the misidentification probability of each user behavior scenario in the set of user behavior scenarios; Judge whether the misidentification probability is greater than a preset probability threshold. If it is judged that the misidentification probability is greater than the probability threshold, then obtain multiple misidentification scenarios; Generate a false alarm scenario set by aggregating multiple misidentification scenarios, and filter the unified data stream according to the false alarm scenario set to obtain the accurately identified target data stream.

[0030] In application, taking a 120-square-meter three-bedroom and one-living-room residence as an example, collect the daily routine data of Mr. Wang, a user, through a mobile APP: getting up at 7:00 on weekdays (activity in the bedroom), leaving home at 8:30 (front door opening), returning at 18:30 (front door closing), and having activities in the living room at 20:00. Divide 12 scenarios such as morning dressing (7:00 - 7:30) and night movie watching (20:00 - 22:00). After evaluation, it is found that the misidentification rate of the pet dog (a golden retriever, weighing 30 kg) running in the living room from 19:00 to 20:00 is 78%, and the misidentification rate of the curtain swaying (when the wind speed is 3 m / s) is 65%. Set the probability threshold to 60% to generate a false alarm scenario set including pet activities and curtain swaying. When a living room movement signal (coordinate area X: 2 - 3 m, Y: 1 - 2 m) appears in the unified data stream and the timestamp is 19:30, compare the characteristics of the false alarm scenario set (moving speed 1.5 m / s, heat source size 40 cm × 60 cm) to filter the data stream, reducing the alarm trigger rate from 5.2 times per day to 0.8 times.

[0031] Steps for performing real-time privacy collection on the target data stream to obtain a privacy data block and performing real-time privacy processing on the privacy data block are as follows: Classify the target data stream to obtain a video data stream and a signal data stream collected by security devices; Based on the video data stream, perform dynamic polarization filtering on the video data stream to obtain a target video data stream with clear images; Perform privacy identification on the target video data stream to obtain a video privacy data block, and perform real-time video blurring processing on the video privacy data block; Based on the signal data stream, perform signal content identification and signal enhancement on the signal data stream to obtain a target signal data stream with complete signals; Perform privacy identification on the target signal data stream to obtain signal privacy data blocks, and perform real-time signal blurring processing on the signal privacy data blocks.

[0032] In operation, taking a 120-square-meter three-bedroom and one-living-room residence as an example, the system separates the data stream of the entry camera into a video stream (1920×1080@30fps) and a door magnetic signal stream (switching quantity). Apply a polarization filter (angle 45 degrees) to the video stream to eliminate the glass reflection interference (the brightness of the reflection area drops from 250 cd / m² to 80 cd / m²). After identifying the face area of the visitor in the picture (pixel coordinates X400-600, Y300-500), perform Gaussian blurring processing (radius 15 pixels). After the door magnetic signal is enhanced by an amplifier circuit (the signal amplitude is increased from 0.3V to 3.3V), identify a wireless signal (2.4GHz band) containing the mobile phone number "13845821234", and replace the number field with asterisks. The facial features in the processed video stream are unrecognizable, and the signal log shows "User 138****1234 connected".

[0033] Steps for performing security risk analysis on the target data stream to obtain home security risks and giving risk warnings to the user's mobile phone or performing alarm processing according to the home security risks are as follows; Based on the picture data stream, perform picture recognition on the picture data stream to obtain portrait pictures, behavior pictures, and disaster pictures; Perform security risk assessment on the portrait pictures and behavior pictures to obtain the first picture risk, perform security risk assessment on the disaster pictures to obtain the second picture risk, and combine the first picture risk and the second picture risk to obtain the picture security risk; Based on the signal data stream, perform abnormal signal identification on the signal data stream to obtain abnormal signals, and extract the signal strength and signal frequency of the abnormal signals; Based on the signal strength and signal frequency, obtain the signal security risk, and combine the signal security risk and the picture security risk to generate the home security risk; Based on the home security risk, generate a security risk warning, send the security risk warning to the user's mobile phone, and record the operation time of the user's mobile phone from receiving the security risk warning to confirming the security risk warning; Judge whether the operation time is greater than a preset time threshold. If it is judged that the operation time is greater than the preset time threshold, extract the risk type of the home security risk and report to the corresponding unit according to the risk type.

[0034] In operation, taking a 120-square-meter residence with three bedrooms and one living room as an example, the system analyzes the video of the kitchen camera, detects a smoke-filled area (occupying 40% of the area, Y value of YUV color < 50), and determines it as a secondary fire risk. At the same time, the door magnetic sensor detects abnormal vibrations (frequency 15 Hz, duration 120 seconds), which is evaluated as a tertiary intrusion risk. The comprehensive home security risk value is 78 / 100. A push notification (title "Abnormal Smoke Alarm in the Kitchen") is sent to the user's mobile phone, and the user response time is recorded as 85 seconds (preset threshold 60 seconds). The system automatically activates the alarm process: sending location data (latitude 31.2304°N, longitude 121.4737°E) to the 119 fire alarm center and sending a help request message (room number 902) to the property management. At the same time, a voice alarm is activated (volume 85 dB, content "Fire detected, alarm has been sent").
