vlg Smart Safety Helmet

　　I. Core Product Features (Focusing on the Dual Core of "Safety + Intelligence")

　　The VLG Smart Safety Helmet is based on "industrial-grade protection and extended with intelligent functions." It integrates VLG communication hardware and sensor technology, with core features divided into three dimensions:

　　Industrial-Grade Safety Protection Foundation

　　Material and Structure: The main body uses ABS engineering plastic (lightweight version) or carbon fiber composite material (high-strength version), conforming to GB 2811-2019 "Head Protection - Safety Helmets" standard. It boasts excellent impact resistance (a 1kg steel hammer falling from a height of 1m, shell deformation ≤50mm, impact force ≤5kN) and puncture resistance (a 3kg steel cone falling from a height of 1m, without penetrating the shell); the liner uses a high-density EPS cushioning layer, with a head circumference adjustment range of 54-62cm to suit different workers.

　　Specialized Protection Designs:

　　II. Typical application scenarios (combined with the needs of high-risk industries)

　　Construction scenario

　　Product form: Lightweight ABS smart safety helmet (weight ≤500g, reducing the burden of wearing for a long time), equipped with a detachable camera and LED warning light

　　Core functions:

　　Real-time video monitoring: Construction workers wear safety helmets, and managers can view on-site video (1080P) via the cloud. High-quality images; remote annotation of construction issues (e.g., "scaffolding not secured here"); instructions are transmitted in real-time via speaker.

　　Area boundary crossing warning: Hazardous areas (e.g., under foundation pits, tower cranes) are delineated via RFID positioning. When personnel approach, the safety helmet triggers a local audible and visual alarm (buzzer + flashing red light) and simultaneously reports to the management platform.

　　Emergency assistance: In case of emergencies (e.g., collapse, electric shock), pressing and holding the side button on the safety helmet for 3 seconds triggers an SOS alarm, automatically uploading location and on-site video to the emergency terminal.

　　Compatible technologies: VLG 4G module (ensuring video transmission bandwidth) + LDS GNSS antenna (high-precision positioning) + UHF RFID tag (area access management).

　　Mine underground operation scenario

　　Product form: High-strength carbon fiber smart safety helmet (30% improved impact resistance), integrating an anti-fog visor and gas sensor; the helmet shell is treated with anti-static coating.

　　Core functions:

　　Gas concentration monitoring: Built-in methane/ Carbon monoxide sensor: When the concentration exceeds the standard (methane ≥ 1.0%, carbon monoxide ≥ 24 ppm), the safety helmet immediately alarms (volume ≥ 90dB) and simultaneously uploads data to the underground monitoring center, triggering ventilation equipment linkage; Weak signal communication: In areas with weak underground signal, VLG adaptive signal adjustment technology (temporarily boosting gain by 5dB) ensures uninterrupted 4G/NB-IoT communication, enabling "personnel positioning + voice dispatch"; Equipment collaboration: Interacts with mining AGVs, tunneling machines, and other equipment via RFID. When the safety helmet approaches the equipment, it automatically receives operating instructions (e.g., "Tunneling machine is running, do not approach"), avoiding accidents caused by misoperation; Compatibility technology: VLG anti-interference 4G module (resisting underground electromagnetic interference) + high-sensitivity gas sensor + anti-fog mask (suitable for dusty mining environments); Power inspection scenario; Product form: Insulated smart safety helmet (voltage withstand 15kV/1min), camera with waterproof shell (IP67) (Protection), supports infrared thermal imaging (optional)

　　Core Functions:

　　Equipment Defect Detection: Inspectors use the safety helmet's camera to photograph transmission lines and transformers; AI automatically identifies defects (such as broken conductor strands, damaged insulators); the infrared version can detect abnormal equipment temperatures (such as overheated connectors);

　　Inspection Route Tracking: GNSS records the inspection path, generating an electronic ledger (including inspection time, location, and equipment status) to avoid missed or false inspections;

　　Remote Technical Support: In case of complex faults (such as abnormal transformer noise), a remote video connection can be initiated, allowing experts to view details through the safety helmet's camera and guide on-site operations (such as "disconnect the 10kV switch first").

　　Adaptation Technologies: VLG NB-IoT module (low power consumption, adapted for battery life) + Insulating helmet (protection against electric shock) + Infrared thermal imaging module (equipment temperature detection)

　　III. Core Technology Adaptation (VLG Hardware Capability Migration)

　　Communication and Positioning Technology Adaptation

　　Miniaturization Integration: Integrating VLG 4G/NB-IoT module, LDS GNSS antenna, UHF RFID... The tag is integrated into the gap between the helmet brim and liner (space ≤10cm³), connected via an ultra-fine FPC harness (0.08mm²), without affecting the helmet's protective structure, reducing the size by 40% compared to traditional external modules. Weak signal optimization: Borrowing interference suppression technology from VLG signal amplifiers, in complex environments such as mines and tunnels, through "frequency band filtering + dynamic gain adjustment," the communication signal-to-noise ratio is improved by 40%, and the disconnection rate is reduced from the industry average of 3% to 0.5%. Improved positioning accuracy: Utilizing a VLG dual-mode GNSS antenna (BeiDou + GPS), combined with base station positioning assistance, positioning accuracy remains at 1-3 meters in scenarios such as high-rise building obstruction and underground mining, meeting the needs for area boundary crossing and trajectory tracking. Enhanced safety and durability. Protective collaborative design: The intelligent hardware (modules, sensors) is encapsulated in a waterproof insulating box (IP67). Protective features include: embedding the helmet shell inside to prevent direct impact; the wiring harness is wrapped with aramid fiber (tensile strength ≥10N) to prevent breakage during construction.

　　Extreme environment adaptability: wide-temperature components (-30℃~85℃) are selected, such as VLG industrial-grade 4G modules (compliant with IEC 60068-2-1 standard) and high-temperature resistant lithium batteries (-20℃~60℃ normal charging and discharging), ensuring stable operation in high-temperature workshops and frigid outdoor environments.

　　Electromagnetic compatibility: VLG electromagnetic shielding technology (aluminum foil + copper braided mesh double-layer shielding) prevents electromagnetic interference between electronic components inside the helmet and electrical equipment or mining machinery, complying with GB/T 17626.3-2016 electromagnetic compatibility standard.

　　Industry platform compatibility:

　　Data interface standardization: SDK development package is provided, supporting integration with mainstream industrial IoT platforms (Huawei Cloud IoT, Alibaba Cloud Link, Siemens MindSphere).
