1、 Intelligent follow-up: redefining the "vital signs" of mobile carriers
1. Luggage: From Load Carrying Tools to Autonomous Companions
-Centimeter level tracking: Based on UWB pulse signals and TDoA (Time Difference of Arrival) algorithm, the luggage can lock the owner's position in real time, dynamically maintain a tracking distance of 0.5-1.5 meters, and control the error within ± 3cm
2. Logistics car: from mechanical transportation to intelligent collaborators
-Human vehicle collaboration mode: Identify the operator's identity and orientation, maintain a safe distance of 1 meter and move synchronously, freeing up hands for handling
-Multi device formation: Through UWB Mesh networking, multiple small cars autonomously form a transportation queue with a path error of less than ± 5cm
2、 Technical core: How does UWB create a miracle of spatial intelligence?
Disruptive Principles of Physics
UWB (Ultra Wideband) abandons traditional sine wave communication and instead emits nanosecond level non sine narrow pulses, bringing three inherent advantages:
-Centimeter level positioning: pulse bandwidth of over 500MHz, time resolution of one billionth of a second, achieving ± 3cm ranging accuracy (Bluetooth/WiFi accuracy>1 meter)
-Strong penetration anti-interference: The 3.1-10.6GHz ultra wide spectrum penetrates metal boxes and concrete walls, and the error is still less than 10cm in multipath environments
-Physical level security: signal power is lower than electronic noise, interception probability is almost zero, combined with dynamic live detection to prevent forgery
Feirui Technology Closed Loop: Precise Control from Perception to Action
1. Spatial neural: SIP series built-in 2dBi high gain antenna, real-time positioning within 100 meters
2. Decision brain: Kalman filtering algorithm suppresses noise, IMU dynamically perceives dense scenes with thousands of people and still tracks stably
3. Motion control: The wheel hub motor receives instructions from the 22nm process chip, with a response delay of less than 20ms
3、 Feirui UWB's breakthrough: redefining the technological ceiling
1. Chip level miniaturization revolution
-7 × 7mm ultra-thin body (FS100 chip): 3D heterogeneous integrated RF front-end+baseband processor+antenna, with a volume reduced by 60% compared to traditional modules
-AIP antenna packaging technology: antenna gain increased to 2dBi, signal strength increased by 40% in metal environments
2. Power consumption disruption: Button batteries drive long-lasting life forms
-Dynamic Voltage Regulation Technology (DVFS): standby power consumption<15 μ W, operating power consumption<50mW
-2032 button battery power supply: supports continuous operation of luggage for 20 hours, crossing 3 international terminals
3. Industrial level robustness: 'Undead Follow' in extreme environments
--40 ℃~85 ℃ wide temperature operation: ice and snow airport/high-temperature workshop does not malfunction
-Triple guarantee of anti loss mechanism: over distance alarm+GPS feedback+collaborative tracking with self-organizing network
