D12 Safety Helmet Positioning Terminal

The D12 is an IP66 low-power safety helmet-specific positioning terminal, 4G Cat1 full network compatible, supporting BeiDou/GPS dual-frequency RTK centimeter-level high-precision positioning, integrating satellite/WiFi/Bluetooth beacon/LBS indoor and outdoor integrated positioning.

Product Description

It features a built-in three-axis fall sensor, three function buttons, TTS voice broadcast, and SOS one-button emergency call.

Key Selling Points

● RTK centimeter-level high-precision positioning , outdoor accuracy 0.1-1 meter, supports single BeiDou/dual-mode dual-frequency multi-solution customization.

● Seamless indoor and outdoor positioning integration: outdoor satellite + WiFi + indoor Bluetooth beacon (high accuracy can be achieved with 4-8 meter deployment).

● Fall detection, electronic fences, SOS one-click emergency call, and check-in multi-type safety alarms provide comprehensive coverage.

● TTS (Text-to-Speech) remote text-to-speech broadcast allows the device to directly remind workers of notifications sent from the backend.

● Low-power MCU solution with standby current as low as 5uA and a battery life of ≥15 hours under 8-hour working conditions.

● IP66 dustproof and waterproof, explosion-proof certification can be obtained with third-party testing, compliant with high-risk chemical/coal mining environments.

● Magnetic 4-pin fast charging contacts, fully charged in 1 hour; three-color status indicator lights provide clear information on device status.

● Compatible with JT808/Ntrip differential protocols, simple platform integration, and supports customized software and hardware development for customers.

Feature Introduction

Core Competencies: RTK differential centimeter-level positioning + Bluetooth beacon indoor full coverage, enabling comprehensive monitoring of personnel at high-risk construction sites.

Ordinary personnel terminals only provide positioning within 10 meters. This product supports BDS/GPS dual-mode dual-frequency RTK differential positioning, achieving a maximum outdoor positioning accuracy of 0.1 meters. Indoor positioning can be achieved by deploying Bluetooth beacons (at 4-8 meter intervals), providing full visibility of personnel locations in basements, workshops, and tunnels, thus solving the pain point of blind spots in indoor positioning on construction sites.

● Multiple safety warning mechanisms include a three-axis gravity sensor that automatically detects falls and immediately reports them to the platform; a customizable electronic fence that provides real-time alerts for crossing boundaries or entering high-risk areas; and a long press of the SOS button for one-click emergency help, simultaneously uploading the real-time location.

● Multifunctional smart check-in: Three methods are available to meet the attendance needs of construction sites: physical button check-in, GPS area check-in, and Bluetooth beacon check-in.

● TTS Remote Voice Broadcasting: Text commands are issued from the management backend, and the device speakers directly broadcast notifications and safety warnings.

● Flexible location reporting cycle: 1s~120s. Customizable upload frequency: high frequency during movement, automatic sleep mode when stationary to save power.

● Three-color status LEDs: Independently distinguish between power, satellite, and 4G network statuses, providing a clear display of charging/low battery/successful positioning status.

Application Scenarios

Smart construction sites, chemical industrial parks, coal mines, power line inspections, emergency rescue, road maintenance, and field personnel safety attendance tracking.
