[0011] All hardware devices in stores across the country are remotely connected via the Internet to achieve automatic device topology discovery, dual-channel redundant communication and dynamic load balancing.

[0019] Calculate the detection rate and false alarm rate in real time. The detection rate is calculated based on the missed reading statistics method of the time window. The formula is η = (number of effective alarms) / (number of expected triggers) × 100%, where the number of expected triggers = the number of EPCs on the sales whitelist × the anti-theft device coverage rate;

[0020] Based on alarm event pattern recognition technology and adaptive threshold adjustment mechanism, the false alarm rate is calculated as μ = (number of false alarms) / (total number of alarms) × 100%, and a time decay factor μ' = μ × e^(-λΔt) is introduced;

[0021] The anti-theft alarm is triggered when the detection rate is lower than 95% or the false alarm rate is higher than 5%;

[0022] Dynamically adjust the anti-theft alarm threshold, the formula is T_n=αT_(n-1)+(1-α)μ', where α∈[0.6,0.8].

[0023] According to one aspect of the present invention, the anti-theft alarm comprises:

[0024] When the detection rate or false alarm rate of an anti-theft device is lower than the set value, an alarm will be automatically pushed and a maintenance notification will be generated;

[0041] Efficient remote maintenance and management

[0042] Through the device access layer, remote connection to hardware equipment in stores across the country is achieved, and data collection and real-time maintenance are completed simultaneously, which greatly reduces on-site maintenance costs and response time (fault response is shortened from 48 hours to 2 hours, an 80% increase in efficiency).

[0043] It supports real-time monitoring of equipment status, fault code self-diagnosis, dual-channel redundant communication and hardware abnormality warning to ensure stable system operation.

[0044] Intelligent anti-theft performance optimization

[0045] Adaptive algorithms are used to dynamically calculate the detection rate (η) and false alarm rate (μ), and the performance of anti-theft devices is accurately quantified based on a 7-day / 30-day sliding window missed reading statistical model and alarm event pattern recognition technology.

[0046] Dynamically adjust the warning threshold (T_n=αT_(n-1)+(1-α)μ'), introduce a time decay factor to suppress historical false alarm interference, and reduce the false alarm rate to below 0.3% (industry average 2.1%).

[0047] When the detection rate is <95% or the false alarm rate is >5%, an L2 level warning is automatically triggered and a maintenance work order is generated to ensure the efficient operation of the anti-theft system.

[0048] Accurate fitting behavior analysis

[0049] By linking RFID with door magnetic sensor data, the fitting time (ΔT = avg(t2'-t1')) is accurately calculated, and a fitting-to-purchase conversion rate matrix is established to reveal the correlation between product fitting behavior and sales conversion.

[0050] Generate heat maps to visualize hot spots for fitting activities in stores, provide intelligent suggestions such as product display optimization and fitting room layout adjustments, and increase sales conversion rates by 40%.

[0051] Automated analysis of the entire process reduces manual intervention, improving store operation efficiency and scientific decision-making.

[0052] Layered architecture ensures system scalability

[0053] The three-tier architecture of device access layer - data processing layer - business application layer supports multi-protocol compatibility (MQTT / HTTP / CoAP) and multi-module expansion to meet the needs of stores of different sizes.

[0054] Local + distributed caching mechanism (memory LRU, SQL, Redis) and request priority queue management reduce server load pressure (actually measured concurrency pressure is reduced by 65%). BRIEF DESCRIPTION OF THE DRAWINGS

[0064] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0065] Example 1

[0066] like Figures 1 to 7 As shown in the figure, the system architecture of the intelligent store IoT method and system adopts a layered architecture design:

[0067] Device access layer:

[0068] Supports MQTT / HTTP / CoAP protocols to receive connection requests from store hardware devices (such as RFID readers and infrared sensors).

[0069] It complies with the standard protocol of the Internet of Things industry and is suitable for the compatibility requirements of different hardware devices (for example, RFID readers often use MQTT, while sensors may use CoAP). In this embodiment, the RFID readers deployed in clothing stores are connected through the MQTT protocol, and the access control sensors use the CoAP protocol to upload timestamps.

[0070] In this embodiment, a clothing store deploys 10 RFID readers and 5 access control sensors, and sends connection requests to the devices through the MQTT protocol. The device access layer maintains the link status through heartbeat packets (interval ≤ 5 seconds), and the system monitors the device status through the heartbeat packet status code (0 / 1 / 2).

[0071] Data processing layer:

[0072] Contains data cleaning, whitelist comparison and request queue management modules.

[0073] RFID data cleaning:

[0074] RFID data cleaning rules

[0075] Remove duplicate EPC codes: This solves the redundancy caused by reading the same product multiple times.

[0076] Timestamp calibration (±50ms): Corrects sensor clock deviation.

[0077] Whitelist comparison:

[0078] EPC whitelist source: a list of legal product labels in the store’s product database.

[0079] Blacklist rules: Combine brand characteristics (such as the serial number patterns of luxury goods labels) and a dynamically updated blacklist library.

[0080] In this embodiment, the EPC code E200345678 of women's clothing in the store is searched. When the EPC code E200345678 does not hit the memory cache, the SQLite database is automatically queried to verify the legitimacy.

[0081] Cache mechanism: Use three-level cache (memory LRU → SQLite → Redis) to reduce database access frequency;

[0082] Memory LRU cache: capacity 10,000 entries, refresh cycle 5 seconds.

[0083] SQLite response time: ≤500ms.

[0084] Redis response time: ≤100ms.

[0085] Request queue management: Prioritize POS and third-party API requests (QoS grading) to ensure core business processes.

[0086] Business application layer:

[0087] Provides equipment management, performance analysis and sales-related modules.

[0088] Device management: supports remote login, parameter configuration and firmware upgrade;

[0089] Sales association analysis: Optimize product display strategies based on fitting behavior data (such as RFID reading and door magnetic trigger time) to increase fitting conversion rates (for example, the women's clothing category increased from 32% to 38%).

[0090] like Figure 1 As shown, a smart store Internet of Things method includes the following steps:

[0091] Step S1: By receiving the connection request of the store hardware equipment, data collection and remote maintenance management are carried out synchronously;

[0092] Step S11: device access and protocol adaptation;

[0093] Multi-protocol support: The device access layer is compatible with MQTT / HTTP / CoAP protocols through a dynamic protocol parsing engine.

[0094] Technical implementation: Deploy a protocol identification module to automatically identify the protocol type based on data packet features (such as MQTT fixed header and CoAPOption field); use a protocol conversion gateway to convert heterogeneous protocols into a unified internal format (such as JSON over MQTT).

[0095] In this embodiment, the RFID reader sends the product tag EPC code (topic: / store001 / RFID / data stream) through the MQTT protocol and the access control sensor uploads the trigger timestamp through the CoAP protocol. The system dynamically converts it into the MQTT format and enters the data processing layer to realize device access and protocol adaptation.

[0096] Heartbeat keepalive and status monitoring:

[0097] The device sends a heartbeat packet containing a status code (0 = normal / 1 = offline / 2 = abnormal) at intervals of ≤ 5 seconds;

[0098] Step S12: data collection and preprocessing;

[0099] Real-time data diversion: High-priority data (such as anti-theft alarms and POS transaction records) is directly transmitted to the data processing layer through the main TCP / IP channel; non-real-time data (such as logs and configuration files) is processed asynchronously through the Kafka message queue.

[0100] Data cleaning and standardization: The cleaning rules are to remove duplicate EPC codes and correct timestamp deviation (calibration within ±50ms).

[0101] Step S13: remote maintenance collaboration;

[0102] Fault self-check logic: Health check items: CPU usage > 80%, network delay > 500ms, firmware version expired;

[0103] Diagnostic rules: Single abnormality → P2 level alarm; Two or more abnormalities → P1 level alarm;

[0104] Remote command channel: Maintenance commands are encrypted via TLS 1.3, and support is provided for SSH tunnel penetration to perform firmware upgrades (e.g., to fix CVE vulnerabilities).

[0105] Security control: two-step verification (OTP+biometrics), operation logs synchronized to blockchain for evidence storage.

[0106] Step S2: performing anti-theft processing on the data, and performing anti-theft effectiveness self-diagnosis analysis using an adaptive algorithm to output analysis results;

[0107] Step S21: data theft prevention processing mechanism;

[0108] EPC whitelist comparison:

[0109] Three-level cache architecture:

[0110] In-memory LRU cache (10,000 entries / 5-second refresh) → SQLite database (500ms response) → Redis cluster (100ms response).

[0111] In this embodiment, when the RFID reader uploads the EPC code E200345678, the system prioritizes a hit in the memory cache, and queries the database if a hit is not found.

[0112] Abnormal data interception:

[0113] Blacklist rule: The EPC code is not on the whitelist and matches common stolen tag features (such as luxury brands);

[0114] Step S22: Quantitative analysis of adaptive anti-theft effectiveness;

[0115] Detection rate (η) calculation:

[0116] Detection rate η = (number of effective alarms) / (number of times that should be triggered) × 100%;

[0117] Number of triggers = number of EPCs on the sales whitelist × anti-theft device coverage rate.

[0118] In this embodiment, the specific implementation is:

[0119] Number of times the trigger should occur = number of whitelisted products × covered store area × time window (e.g. 95% within 1 hour);

[0120] When η=92%, the system is marked as "to be optimized" state (below the 95% threshold).

[0121] Dynamic adjustment of false alarm rate (μ):

[0122] Introducing a time decay factor: μ' = μ × e^(-λΔt) (λ = 0.05 / day) to suppress occasional false alarms;

[0123] Step S23: early warning and disposal process;

[0124] Multi-level early warning mechanism:

[0125] Level 0 (Normal): η ≥ 95% and μ ≤ 5%;

[0126] Level 1 (Attention): η < 95% for 3 consecutive days or μ > 5%;

[0127] Level 2 (Emergency): η < 90% or 5 consecutive false alarms;

[0128] Set a sliding time window (7 days / 30 days). When η < 95% or μ > 5% in 3 consecutive window periods, trigger a Level 2 warning;

[0129] Obtain the dynamic adjustment formula based on the statistical dynamic threshold adjustment model: T_n = αT_(n - 1)+(1 - α)μ'(α ∈ [0.6, 0.8]).

[0130] Automatically generate an analysis report:

[0131] Output a PDF report to visualize the data analysis results. The report includes:

[0132] Anti-theft device health score (0 - 100); Heat map of high-risk areas (clustered based on historical false alarm points); Maintenance suggestions (such as adjusting the angle of the RFID reader to reduce the missed reading rate).

[0133] Step S3: Based on the analysis results, conduct an association analysis on the fitting behavior data and output a behavior analysis report.

[0134] Step S31: Multi-sensor data fusion;

[0135] Spatio-temporal alignment algorithm:

[0136] Align the RFID reading timestamp t1 with the access control sensor trigger timestamp t2, and calculate the fitting duration ΔT = avg(t2' - t1');

[0137] Specifically, customer A scans the code to start fitting at 10:00:00 and triggers the door magnetic at 10:15:30. The system identifies t1' = 10:00:05 (first scan), t2 = 10:15:30, and ΔT = 925 seconds.

[0138] Repeat fitting filtering:

[0139] Define a time threshold T (such as 30 minutes): If t1'' - t1' < T for the same customer, mark it as a repeated fitting and exclude it from the statistics.

[0140] Step S32: Association analysis model;

[0141] Purchase conversion rate matrix:

[0142]

[0143] Establish a fitting-sales association model: correlation degree K = number of purchases after fitting / (total number of fittings - number of repeated fittings).

[0144] Step S33: data push and query;

[0145] The statistical results are pushed to the platform through the device for managers to browse and query, and optimize product layout and sales strategies.

[0146] Advantages of the present invention: Through the above solution, the present invention has achieved significant technological breakthroughs in equipment access and management, data security and anti-theft, sales behavior analysis, etc. The specific advantages are as follows:

[0147] 1. Efficiency of device access and protocol adaptation

[0148] Multi-protocol compatibility: Supports MQTT / HTTP / CoAP protocols to adapt to the communication needs of devices from different manufacturers and avoid access difficulties caused by protocol incompatibility.

[0149] Example verification: A clothing store deployed 10 RFID readers and 5 access control sensors, achieved stable connection through the MQTT protocol, and achieved a 100% device online rate.

[0150] Heartbeat keepalive mechanism: The device sends heartbeat packets at intervals of ≤5 seconds to ensure link stability and monitor device status (normal / offline / abnormal) in real time.

[0151] Effect comparison: Compared with the traditional fixed heartbeat interval (such as 30 seconds), the fault detection time is shortened to within 5 seconds, reducing the risk of business interruption due to device offline.

[0152] Protocol conversion gateway: Automatically identify heterogeneous protocols (such as CoAP→MQTT), unify internal data formats, and reduce system integration complexity.

[0153] 2. Efficiency and security of data processing

[0154] Three-level cache mechanism: Use memory LRU → SQLite → Redis three-level cache to reduce database access frequency and improve data processing speed.

[0155] Performance comparison: RFID data query response time is optimized from 500ms in traditional solutions to ≤100ms, and the cache hit rate reaches over 95%.

[0156] QoS priority scheduling: hierarchical processing of POS machine and third-party API requests to ensure the real-time performance of core business processes (such as payment transactions).

[0157] Data cleaning and standardization: Automatically remove duplicate EPC codes and correct timestamp deviations to ensure data quality.

[0158] 3. Intelligent and adaptive optimization of anti-theft performance

[0159] EPC whitelist comparison: The three-level cache architecture (memory LRU → SQLite → Redis) enables fast comparison with a response time of <50ms.

[0160] Quantitative analysis of adaptive anti-theft effectiveness:

[0161] Detection rate (η) calculation: A time-window-based missed read statistics method is used to dynamically evaluate the performance of anti-theft devices.

[0162] Verification of the embodiment: When η=92%, the system is marked as "to be optimized" and it is recommended to adjust the position of the RFID reader.

[0163] Dynamic adjustment of false alarm rate (μ): Introduce the time decay factor μ' = μ × e^(-λΔt) to suppress the impact of occasional false alarms.

[0164] Effect comparison: A sensor falsely triggered an alarm due to a thunderstorm in the store. After three days of attenuation, μ dropped from 2.5% to 0.8%, reducing false alarm interference.

[0165] Multi-level warning mechanism: L0 (normal) → L1 (concern) → L2 (emergency) graded warning, combined with sliding window statistics to improve warning accuracy.

[0166] 4. Accuracy of sales behavior analysis and decision support

[0167] Multi-sensor data fusion: The RFID reading timestamp t1 is linked with the access control sensor trigger timestamp t2 to calculate the fitting time ΔT and filter repeated fitting behaviors.

[0168] Purchase conversion rate matrix: Optimize product display strategies based on fitting behavior data to increase sales conversion rates.

[0169] Data push and query: Statistical results are pushed to the management platform in real time, supporting online browsing and historical data query to assist operational decision-making.

[0170] Managers' decision-making cycles were shortened from weeks to hours, and inventory turnover increased by 15%.

[0171] 5. Remote maintenance and improved operation and maintenance efficiency

[0172] Fault self-diagnosis and diagnosis: Automatically detects health status such as CPU usage, network latency, and firmware version, and triggers graded alarms when abnormalities occur.

[0173] Remote command channel: supports SSH tunnel penetration to perform firmware upgrades, ensuring safe and stable system operation.

[0174] Optimized operation and maintenance costs: Remote maintenance coverage increased to 95%, and on-site maintenance needs were reduced by 80%.
