Description

Technical Field

[0001] This invention relates to the field of fire safety technology, specifically a public environment safety and evacuation system. Background Technology

[0002] Fire safety protection in public places largely relies on a basic protection system consisting of traditional electrical protection devices, stand-alone smoke sensors, fixed fire alarms, and pre-set evacuation signs. Among these, electrical circuits mainly achieve overload and short-circuit protection through ordinary circuit breakers, smoke detection relies on a single sensor to trigger an alarm, and evacuation guidance is mostly based on fixed signs and unified broadcast instructions. Some places also use surveillance cameras for post-event tracing. These existing technologies play a basic early warning and protective role in routine safety precautions and have become standard configurations for fire safety in public places. However, existing electrical safety monitoring technologies suffer from low accuracy and slow response. Ordinary circuit breakers cannot collect multi-dimensional data such as current, voltage, and conductor temperature in real time, and can only passively trip after a fault occurs. Furthermore, they are difficult to quickly locate the physical area of ​​abnormal circuits, leading to blind investigation and inefficient handling of electrical hazards, which can easily cause fires to escalate. Moreover, evacuation guidance lacks dynamic adaptability, fixed evacuation routes cannot be adjusted in real time according to the direction of fire spread, and no special rescue plans have been designed for groups with mobility difficulties such as the elderly, pregnant women, and people with disabilities. This can easily lead to secondary risks such as evacuation congestion and stampedes, and the rescue of special groups is not targeted or efficient. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a public environment safety and risk avoidance system, which solves the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a public environment safety and hazard avoidance system, comprising the following steps: S1. Hardware Deployment: Install digital intelligent circuit breakers in all electrical circuits in public places and connect them to the central management platform; deploy smoke sensors according to specifications; install high-definition intelligent cameras and associate them with corresponding area smoke sensors; deploy zoned fire alarms and intelligent broadcasting systems; and input the site layout and preset main evacuation routes into the central management platform. S2, Information Pre-configuration: Input the rated parameters of electrical circuits into the platform and preset the electrical safety threshold and the smoke safety threshold, and build a feature library containing feature tags of people with mobility impairments; S3. Real-time data acquisition and monitoring: Digital intelligent circuit breakers and smoke sensors collect corresponding data at a set frequency and upload them to the platform. Cameras collect data in low-power standby or low frame rate mode, and switch to high-definition collection after being triggered. S4. Emergency Response in Different Scenarios: The platform compares the collected data with preset thresholds and performs emergency handling for electrical anomalies and emergency handling for smoke and fire anomalies, respectively. S5. Personnel Identification: By capturing images from cameras and matching them with a database of characteristics of people with disabilities, relevant information about people with disabilities is marked and the number of ordinary people is counted. S6, Dual-Route Guided Rescue: The system dynamically adjusts evacuation routes for ordinary personnel and provides guidance via broadcasts, while generating personalized support routes for people with mobility impairments and sending them to rescue personnel's terminals.

[0005] Furthermore, in step S1, smoke sensors are deployed at least one per 50 square meters in evacuation routes, densely populated areas, etc., high-definition smart cameras support motion tracking and feature recognition, and the smart broadcasting system can be controlled by area.

[0006] Furthermore, in step S2, the electrical safety thresholds include an overload threshold of 1.2 times the rated current, a leakage current threshold of 30mA, and a temperature threshold of 85℃; the smoke safety thresholds comply with the "Design Code for Automatic Fire Alarm Systems"; and the characteristic labels for people with mobility impairments include wheelchairs, strollers, pregnant women's body types, and characteristics related to crutches.

[0007] Furthermore, in step S3, the digital intelligent circuit breaker collects current, voltage, wire temperature, and leakage current data at a frequency of 1 time / second, the smoke sensor collects smoke concentration and concentration rise rate at a frequency of 1 time / 5 seconds, and the camera collects high-definition data at 25 frames / second after being triggered.

[0008] Furthermore, the electrical anomaly emergency handling in step S4 includes: if the circuit data exceeds the threshold, locating the abnormal area, triggering the corresponding digital circuit breaker to automatically trip and disconnect power, recording the abnormal data, and pushing alarm information containing the abnormal location and fault type to the management terminal.

[0009] Furthermore, the emergency handling of abnormal smoke and fire conditions in step S4 includes: when the smoke data exceeds the threshold, the corresponding area camera is triggered to switch to high-definition acquisition and the image recognition module is activated. If flames or continuously spreading dense smoke are detected, it is determined to be a fire, triggering the fire alarm, guiding evacuation through broadcast, and pushing relevant data to the fire control center.

[0010] Furthermore, in step S5, the information related to people with mobility impairments includes location, type, and number, and the types of people include the elderly, children, pregnant women, and people with disabilities.

[0011] Furthermore, in step S6, the evacuation route for ordinary personnel is dynamically adjusted based on the direction of fire spread, which is determined by the smoke diffusion rate and camera footage.

[0012] Furthermore, in step S6, the dedicated support route for people with mobility impairments prioritizes nearby, unobstructed passageways and marks the location of the person requiring assistance.

[0013] Furthermore, the intelligent broadcast system broadcasts the location of the fire, evacuation routes, and evacuation precautions in different areas, and pushes information to the fire control center including the location of the fire, smoke concentration data, and images of the fire area.

[0014] This invention provides a public environment safety and risk avoidance system, which has the following beneficial effects: 1. This public environment safety and disaster prevention system uses digital circuit breakers to collect and compare data such as current, voltage, and temperature of electrical circuits in high frequency and real time, enabling rapid and accurate identification of electrical anomalies. Combined with the automatic power-off and physical area positioning functions of abnormal circuits, it effectively prevents the escalation of electrical overload, leakage and other hidden dangers into fire accidents, avoids the blindness of traditional electrical fault diagnosis, significantly shortens the response time for handling electrical safety hazards, and improves the inherent safety level of public environment electrical systems.

[0015] 2. This public environment safety and evacuation system features a dual-route guidance and rescue plan. For ordinary people, it guides their orderly evacuation through dynamically adjusted pre-stored evacuation routes, effectively reducing secondary risks such as congestion and stampedes during evacuation. For people with mobility impairments, it utilizes the feature recognition and spatial positioning of intelligent cameras, combined with real-time planning of dedicated rescue routes, allowing rescuers to directly locate the target. This solves the problems of insufficient attention to special groups and weak targeted rescue in traditional evacuation and rescue, significantly improving the rescue efficiency and survival probability of people with mobility impairments. At the same time, it avoids the problem of crowd congestion caused by uneven evacuation speeds between people with mobility impairments and ordinary people, and avoids serious problems such as stampedes and pushing caused by panic among the crowd. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the steps of a public environment safety and risk avoidance system according to the present invention. Detailed Implementation

[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0018] like Figure 1 As shown, the present invention provides a technical solution: a public environment safety and risk avoidance system, comprising the following steps: S1. Hardware Deployment: Install digital intelligent circuit breakers for each electrical circuit in public areas (such as socket circuits, lighting circuits, and large equipment circuits) and connect them to the central management platform. In accordance with fire protection regulations, place smoke sensors in areas such as ceilings and equipment rooms (at least one per 50 square meters, covering evacuation routes and densely populated areas). Install high-definition intelligent cameras (supporting motion tracking and feature recognition) in public areas, evacuation routes, elevator entrances, and other locations, and associate them with the smoke sensors in the corresponding areas. Deploy zoned fire alarms (audio and visual) and intelligent broadcasting systems (controlled by area). Record the site layout and preset main evacuation routes (including emergency exits and safety exits) into the central management platform. S2, Information Pre-configuration: Input the rated parameters of each electrical circuit (such as rated current, voltage, and allowable temperature rise) into the platform, preset electrical safety thresholds (such as overload threshold of 1.2 times rated current, leakage threshold of 30mA, and temperature threshold of 85℃); preset smoke safety thresholds (compliant with the "Design Code for Automatic Fire Alarm Systems", such as smoke concentration ≥0.3dB / m³, concentration rise rate ≥0.1dB / m / s); construct a feature database for people with mobility impairments: input feature tags such as wheelchairs, strollers, pregnant women's posture, and canes for subsequent image recognition; S3. Real-time data acquisition and monitoring: The digital intelligent circuit breaker collects data such as current, voltage, wire temperature, and leakage current of the corresponding circuit at a frequency of 1 time / second and uploads it to the central management platform in real time; the smoke sensor collects the smoke concentration and concentration rise rate in the area at a frequency of 1 time / 5 seconds and synchronizes the data to the platform; the camera keeps low power standby (or low frame rate acquisition) and switches to high-definition acquisition at 25 frames / second after being triggered. S4. Emergency Response in Different Scenarios: Emergency handling of electrical anomalies: The platform compares electrical data collected in real time with preset thresholds: If the data of a certain circuit exceeds the threshold (such as the current reaching 1.3 times the rated current), the physical area of ​​the abnormal circuit is immediately located; the digital circuit breaker corresponding to the circuit is automatically tripped and de-energized, and the abnormal data (time, circuit number, and parameter value exceeding the standard) is recorded. Alarm information is pushed to the management terminal (mobile phone, backend), including the abnormal location and fault type, prompting manual re-inspection; Emergency handling of abnormal smoke and fire situations: When the platform determines that the smoke data exceeds the threshold, it immediately triggers the cameras in the corresponding area to switch to high-definition acquisition and starts the image recognition module; the image recognition module analyzes the camera images. If flames or continuously spreading thick smoke are detected, it is determined to be a "fire". If it is determined to be a non-fire situation (such as kitchen fumes or incense), only a warning message is pushed and no fire-fighting action is triggered. After confirming the fire, perform the following operations simultaneously: Trigger the fire alarms and audible and visual alarms in the fire area and adjacent areas; broadcast the fire location by area and guide the expected personnel to evacuate along the planned safe evacuation route, while playing pre-stored evacuation precautions in a loop; at the same time, push the fire location, smoke concentration data, and fire area images to the fire control center. S5. Personnel Identification: The images of the fire area captured by the camera are transmitted to the recognition module in real time. The recognition module matches the feature database of people with disabilities to mark the location (based on the spatial coordinates of the camera), type (elderly, child, pregnant woman, disabled), and number of people with disabilities. At the same time, the number of ordinary people in the area is counted and uploaded to the platform. S6, Dual-Route Guided Rescue: Guidance for ordinary personnel: The platform dynamically adjusts the main evacuation route (such as avoiding the fire spread path) based on the direction of fire spread (determined by the rate of smoke diffusion and camera footage), and updates guidance instructions by area through broadcast; For people with limited mobility, such as the elderly, children, pregnant women, and people with disabilities: The platform combines the real-time location of people with limited mobility, the fire-blocked area, and the current standby point of rescuers to generate targeted support routes (prioritizing nearby, unobstructed passages and marking the location of people who need assistance), and pushes them to the handheld terminals of rescuers. Based on the above description, this invention enables rapid and accurate identification of electrical anomalies by using a digital circuit breaker to collect and compare data such as current, voltage, and temperature of electrical circuits in high frequency and at thresholds. Combined with the automatic power-off and physical area location functions of the abnormal circuit, it effectively prevents the escalation of electrical overload, leakage and other hidden dangers into fire accidents, avoids the blindness of traditional electrical fault diagnosis, significantly shortens the response time for handling electrical safety hazards, and improves the inherent safety level of electrical systems in public environments. This invention also incorporates a dual-route guided rescue scheme. For ordinary people, it guides their orderly evacuation through dynamically adjusted pre-stored evacuation routes, effectively reducing secondary risks such as congestion and stampedes during evacuation. For people with mobility impairments, it utilizes the feature recognition and spatial positioning of intelligent cameras, combined with real-time planning of dedicated rescue routes, enabling rescuers to directly locate the target. This solves the problems of insufficient attention to special groups and weak targeted rescue in traditional evacuation and rescue, significantly improving the rescue efficiency and survival probability of people with mobility impairments. At the same time, it avoids the problem of crowd congestion caused by uneven speeds when people with mobility impairments evacuate together with ordinary people, and avoids serious problems such as stampedes and pushing caused by panic among the crowd.
