vlg Tracker

　　I. Core Product Features (Focusing on "Accurate Tracking + Low Power Consumption and Durability")

　　The VLG Tracker integrates VLG RF technology and low-power hardware design, with "positioning as the core, communication as the link, and protection as the foundation." Its core features are divided into four dimensions:

　　1. Multi-mode High-Precision Positioning Capability

　　Positioning System: Built-in VLG miniature Beidou-3 + GPS dual-mode GNSS antenna (LDS laser engraving process, thickness ≤0.3mm), compatible with GLONASS/Galileo assisted positioning. Positioning accuracy is ≤1 meter in typical outdoor scenarios, ≤3 meters in urban canyon scenarios, and ≤10 meters in indoor weak signal areas (such as warehouses) through "GNSS + LBS base station positioning" fusion.

　　Positioning Frequency: Supports dynamic adjustment (default 10 minutes/time, tracking mode 1 minute/time, emergency mode 10 seconds/time) to adapt to different power consumption requirements.

　　Assisted Positioning: Optional UHF RFID tag (compliant with ISO) 18000-6C), using RFID readers, achieves centimeter-level area positioning in enclosed spaces (such as containers and factories), solving the blind spot problem of pure satellite positioning.

　　2. Low-Power Wide-Area Communication Capabilities

　　Communication Module: Equipped with a VLG NB-IoT/4G dual-mode module (size ≤20mm×15mm×2.5mm), supporting automatic switching between NB-IoT (low power) and 4G (high speed). Standby power consumption in NB-IoT mode is ≤5μA, and voice call power consumption in 4G mode is ≤30mA.

　　Data Transmission: Supports scheduled reporting of location data (e.g., daily asset status synchronization) and abnormal trigger reporting (e.g., displacement exceeding 100 meters, vibration exceeding limits). Single data transmission volume in NB-IoT mode is ≤500 bytes, and monthly data consumption is ≤1MB.

　　Weak Signal Adaptation: Integrates VLG adaptive signal conditioning technology (borrowing from signal amplifier AGC logic). In remote areas (e.g., rural roads, mines), the communication disconnection rate is ≤0.5%/day, and the data retransmission success rate is ≥99.8%.

　　3. Scenario-Specific Protective Design

　　Storage and Interfaces: Local storage of ≥1000 location data entries (cached when network is offline), supports SMA RF interface (for external antenna extension), UART interface (for sensor docking), consumer version additionally supports Bluetooth 5.0 (for viewing data via close-range connection to a mobile phone).

　　II. Technology Adaptation and Scenario Implementation (Connecting to the VLG Solution System)

　　1. Industrial Asset Tracking Scenario (Equipment/Tools/Heavy Machinery)

　　Adaptation Solution: VLG Industrial Tracker + NB-IoT Module + UHF RFID Reader + VLG IoT Cloud Platform

　　Core Value: Solves the pain points of "unclear asset location, low inventory efficiency, and high risk of loss" in industrial scenarios. For example, a car factory used this solution to achieve full lifecycle tracking of welding robots and tooling fixtures.

　　Deployment Logic:

　　The Tracker is installed on the surface of the asset (e.g., the machine casing) and reports its location and status (e.g., vibration value, battery level) periodically via NB-IoT.

　　VLG UHF RFID readers are deployed in the factory. When assets enter or leave the workshop, "entry/exit time + area" is automatically recorded, achieving seamless integration of "satellite positioning + area positioning."

　　Data is accessed through the VLG IoT cloud platform to generate asset trajectory reports and inventory lists. Abnormal displacement (e.g., unauthorized removal from the factory area) triggers SMS/... Platform alert;

　　Key Achievements: Asset inventory efficiency improved by 80% (from 2 days/time manually to 1 hour/time automatically), asset loss rate decreased from 5% to 0.1%, and a single tracker's battery life covers a 3-year asset usage cycle.

　　2. Logistics and Freight Tracking Scenarios (Containers/Pallets/Cold Chain Goods)

　　**Suitable Solution:** VLG Logistics Tracker + 4G Module + Temperature and Humidity Sensor + Signal Amplifier

　　**Core Value:** Meets the "location tracking + environmental monitoring + tamper-proofing" requirements of logistics scenarios. For example, a cold chain logistics company uses this solution to monitor the entire transportation process of fresh produce.

　　**Deployment Logic:**

　　The Tracker is embedded in the container/pallet, with a built-in temperature and humidity sensor (detection range -30℃~70℃/0-100% RH, accuracy ±0.5℃/±3% RH) to monitor the cargo environment in real time.

　　During long-distance transportation, location and temperature/humidity data are uploaded via a 4G module. In remote areas (such as western highways), a VLG signal amplifier is used to ensure uninterrupted data transmission.

　　The platform is equipped with "temperature and humidity threshold alarms" (e.g., fresh produce transportation ≤5℃) and "staying timeout alarms" (e.g., staying at highway service areas for more than 2 hours). (Hours), and push notifications are sent to the logistics management terminal in case of anomalies;

　　Highlights of achievements: Cold chain cargo loss rate reduced from 8% to 2%, transportation anomaly response time shortened from 2 hours to 10 minutes, and single-trip transportation data integrity ≥99.5%.
