In high-density personnel operation scenarios such as smart parks, large factories, and warehousing logistics, traditional personnel management methods are facing multiple challenges. Bluetooth badges that only support short-range clock-in are limited by signal coverage, making continuous cross-area and cross-floor positioning impossible. GPS badges relying on cellular networks can solve wide-area coverage issues, but they have shortcomings such as high power consumption, frequent charging requirements, and insufficient indoor positioning accuracy. The harsh operating environments with high humidity, heavy dust, and strong vibration also impose strict requirements on the industrial protection level of equipment. Building an all-weather personnel safety management system with wide coverage, long battery life, high precision and high durability has become a core pain point in the digital upgrading of enterprises.

Technology Integration: LoRaWAN + BLE Dual-Mode Architecture Defines Next-Generation Badge Tracker

The LoRaWAN Bluetooth Badge Tracker launched by JinShengChang innovatively combines wide-area low-power communication technology with near-field sensing capabilities, building a dual-layer positioning network of "wide-area coverage + precise indoor positioning".

• ‌First Layer: LoRaWAN Wide-Area Backbone Network‌: The device is equipped with a built-in LoRaWAN communication module. Leveraging its ultra-long transmission distance (over 3km in open areas) and ultra-low power consumption, only a small number of outdoor gateways are needed to achieve global control over the on-duty status and general activity areas of personnel across the entire park and factory. The device supports a standby time of 3 to 6 months, completely eliminating the management burden caused by frequent charging.
• ‌Second Layer: BLE Beacon High-Precision Positioning Network‌: In complex indoor environments such as factory interiors, warehouse floors and office buildings, the device scans pre-deployed Bluetooth Beacons to achieve high-precision positioning at meter-level or even sub-meter level. Managers can clearly view the real-time location and movement trajectories of personnel on the backend electronic map.

This dual-mode architecture, where "LoRaWAN manages the overall area and Bluetooth manages key points", accurately solves the dilemma of traditional solutions that "work outdoors but fail indoors" while ensuring long battery life and wide coverage.

Application Value: Full-Scenario Empowerment from Personnel Management to Safety Prevention and Control

JinShengChang LoRaWAN Bluetooth Badge Tracker is not only a positioning terminal, but also an IoT node integrated with multiple safety features.

1. ‌Active Safety Prevention and Control‌: The device is equipped with a physical SOS button. In case of danger, long pressing the button will send a distress signal with precise location to the management platform. Combined with the electronic fence function, it can control access to dangerous and restricted areas and trigger cross-border alerts.
2. ‌Smart Attendance and Working Hours Statistics‌: Combining personnel positioning and preset attendance points, it can automatically generate accurate mobile attendance records and working hour reports, eliminating proxy clock-in and false attendance to improve management efficiency.
3. ‌Collaborative Management of Assets and Personnel‌: In warehousing and logistics scenarios, the badge positioning can be used to quickly dispatch the nearest available operator, or monitor whether personnel operate specific equipment in designated areas, realizing the digital linkage of personnel, assets and work sites.

With profound experience in the industrial IoT field, JinShengChang endows this product with IP67 dustproof and waterproof performance and a rugged housing design, ensuring stable operation in industrial environments with oil stains, dust and high humidity. This solution has been successfully applied in multiple projects including smart manufacturing factories, smart ports and large logistics parks, building a cost-controllable, flexibly deployable, reliable and durable digital foundation for personnel safety for customers.
