Summary of the advantages of single-line laser radar (XD-TOF-05D):
Technical principles and simplified structure
XD-TOF-05D is based on the TOF (time of flight) phase difference ranging principle, and directly calculates the target distance by measuring the time difference between laser emission and reception.
Compared with the traditional triangulation ranging method, TOF technology has the following characteristics:
No mechanical scanning components:
The solid-state design avoids the mechanical wear problem of the rotating mechanism in the traditional single-line radar, and the reliability is significantly improved;
Strong anti-interference ability:
Supports stable operation in complex lighting environments (such as 60Klx strong light outdoors), and adapts to the needs of dynamic scenes such as AGV.
Key advantages:
By optimizing the signal processing unit and TOF algorithm, XD-TOF-05D achieves low-latency real-time environmental perception while ensuring high angular resolution.
Obstacle avoidance strategy implementation
Hierarchical warning mechanism:
Level 1 warning zone (3-5m): slow down and plan a detour path;
Level 2 braking zone (0.05-3m): emergency stop and trigger sound and light alarm.
Multi-target tracking: through the angle-distance matrix algorithm, simultaneously process ≥5 obstacle coordinates, and give priority to avoiding dynamic targets.
System integration and industrial scenario verification
Hardware integration solution：
Installation layout: forward main radar + lateral auxiliary radar (covering AGV turning blind spot);
Communication protocol: CAN bus or RS-485 interface interacts with AGV controller, transmission delay <10ms.
Anti-interference ability test
ability test：
Dust environment: At a dust concentration of 5mg/m³, the ranging error is less than ±1cm;
Light interference: Tolerant to 50,000 lux ambient light (equivalent to direct sunlight at noon).
Typical application cases
Case 1: E-commerce warehouse AGV cluster
Environment: high-density shelves (channel width 1.2m), frequent personnel passage;
Effect: obstacle recognition rate ≥99.7%, false alarm rate <0.3%1.
Case 2: Material handling AGV in the automotive manufacturing industry
Challenges: metal chip interference, strong electromagnetic environment;
Solution: Add metal filtering algorithm to shield non-biological reflection signals.
