Solution Overview
To address the time misalignment among multiple sensors in autonomous driving, the synchronized time-service solution is a high-precision time synchronization technology with broad applications across multiple domains, including communication networks, transportation, and power systems.
ALG-TECH’s synchronized time-service solution ensures that devices, systems and sensors on the network share a unified time standard through various communication protocols (such as PTP/gPTP). It provides hardware trigger signals to multi-channel camera modules and stamps every image frame with a hardware timestamp, achieving nanosecond-level time alignment among cameras, and between cameras and LiDAR, IMU and millimeter-wave radar. This guarantees accurate multi-sensor fusion perception, eliminates perception errors caused by time offset, and enables precise device collaboration and data synchronization across fields such as autonomous driving, industrial automation, smart manufacturing and rail transit.
Key Advantages
●Multi-Channel External Trigger Output
Provides 8 channels of trigger signals at different frequencies,with synchronization accuracy of <200 ns, compatible with10/20/30 fps external trigger inputs. Automotive-grade wide-temperature design ensures long-term stable operation.
●Flexible Time Source Seamless Switching
Via a DIP switch, the synchronization time source can beconveniently switched between GNSS signals and the network master clock (PTP/gPTP Slave).
●Multi-Protocol Master-Slave Compatibility
Fully supports PTP/gPTP protocols; devices can switch flexiblybetween master and slave modes to meet synchronization needs in complex networks.
●Nanosecond-Level Synchronized Trigger
Achieves nanosecond-level synchronization error across multi-channel cameras, with a synchronization accuracy of 200 ns -superior to software timestamp solutions.
●High-Precision Positioning and Timing
Integrates a GPS system and supports PPS and other signals,providing precise longitude/latitude positioning and a time reference.
