Industry Technical Pain Points: The "Three Great Mountains" of Intelligent Transformation in Public Transportation
In the field of public transportation, intelligent transformation has become the core path for improving operational efficiency and ensuring passenger safety. However, the technical implementation of AI video terminals on buses still faces three major challenges: the first being...Difficult to integrate multimodal data——The video, vehicle status, and location data generated by on-board cameras, CAN bus, GPS, and other devices require real-time synchronization processing. Traditional terminals, due to insufficient computing power, can cause delays of up to 300ms or more, failing to meet the millisecond response requirements for emergency events (such as emergency braking, collisions); secondly,Poor adaptability in complex scenarios——Urban public transportation must cope with extreme environments such as strong light, backlight, rain, and snow. The accuracy of traditional terminal image recognition drops below 60% in low-light conditions, leading to the failure of functions such as passenger behavior analysis and driver fatigue monitoring; thirdly,High operation and maintenance costs——Each single device generates over 10GB of data per day, relying on manual inspections at traditional terminals, resulting in a fault troubleshooting cycle of up to 48 hours. Moreover, due to cooling issues, the lifespan of the equipment is generally less than 3 years, directly increasing the total lifecycle cost. These pain points severely restrict the intelligentization process of public transportation and urgently require technological breakthroughs.

FAQ: AI Video Terminal Selection Guide for Buses
Q1: How to choose a terminal chip suitable for high computing power requirements?
A: Focus on the AI computing power, energy efficiency ratio, and interface support of the chip. For example, the Hi3559A chip used in the Lans LSC-AI-V10, with a computing power of 4TOPS and an energy efficiency ratio of 2TOPS/W, supports 8 MIPI interfaces and PCIe 3.0, allowing simultaneous connection of 8 cameras and CAN bus, meeting the needs of multimodal data fusion; whereas some competing chips have only 1TOPS of computing power and insufficient interface numbers, making it difficult to support complex scenario analysis.
Q2: How to ensure image recognition accuracy in complex environments?
A: Hardware and algorithmic optimization is required. In terms of hardware, choose cameras that support wide dynamic range (WDR), such as the Sony IMX335 sensor on the Lans terminal, which has a dynamic range of 120dB and can suppress overexposure of bright areas and loss of details in dark areas. In terms of algorithms, adopt dynamic exposure adjustment and multi-frame fusion techniques, such as Lans' "Adaptive Exposure Algorithm," which can adjust parameters in real-time according to the intensity of ambient light, improving the recognition accuracy of license plates in backlit scenes from 60% to 98%.
Q3: How to reduce the total lifecycle operation and maintenance cost of equipment?
A: Focus on three aspects: equipment lifespan, fault warning, and data management. In terms of equipment lifespan, choosing industrial-grade heat dissipation design (such as Lans terminal's vacuum uniform heat plate + dual-fan cooling) can control the working temperature within 60℃, extending the lifespan from 3 years to 5 years; for fault warning, deploy edge computing modules to monitor equipment status in real-time, with Lans terminal detecting anomalies through voltage and current sensors, achieving a fault warning accuracy rate of 95%; in data management, adopt H.265+ encoding and data compression technology, such as Lans platform reducing the daily data volume per device from 10GB to 2GB, cutting 50% of bandwidth and storage costs.
