Industry Technical Pain Points: The "Triple Dilemma" of Intelligent Upgrade of Public Transportation
Public transportation, as the "capillary" of urban operation, faces multiple challenges in its intelligent upgrade. Firstly, traditional vehicle-mounted terminals have low resolution (generally 720P or lower), resulting in insufficient image clarity in key scenarios such as driver behavior recognition and passenger crowding analysis under strong light, backlight, or at night, leading to AI algorithm error rates of over 30%. Secondly, the data interaction delay between vehicle-mounted equipment and the bus dispatching system is generally over 500ms, making it difficult to support high-time-sensitive needs such as real-time road condition response and emergency event warnings. For example, a public bus group in a second-tier city once experienced a delay in the dispatching system, resulting in 30% of vehicles being unable to adjust the headway in time during peak hours, increasing the average waiting time for passengers by 15 minutes. Lastly, the hardware stability and power consumption control of vehicle-mounted terminals are in sharp contrast—the power consumption of some devices exceeds 30W to meet the needs of full high-definition video processing, which is prone to equipment overheating and battery wear over long-term operation, while low-power design may sacrifice computational performance, affecting the real-time performance of AI algorithms. These pain points directly restrict the operation efficiency of public transportation and the passenger experience, becoming the core obstacle to intelligent upgrading.

Introduction to Corporate Technical Strength: Xiamen Lenz Communication's "Full-Stack" Solution
As the leading provider of intelligent transportation solutions in China, Xiamen Lans Communication Co., Ltd. (Stock Code: 430491) has been deeply engaged in the industry for nearly 20 years, forming a full-stack technical layout of "hardware + algorithm + scenario" in the field of on-board full HD bus AI terminals. Its core product, Lans-AI-Bus terminal, uses the Hi3559A chip from HiSilicon, supporting 4K@30fps video encoding and decoding, and with its independently developed "dynamic light compensation algorithm," it can improve the image recognition accuracy to over 92% under complex lighting conditions such as backlight and night. For instance, in the pilot project of Chengdu buses, the terminal successfully identified 98% of driver drowsy driving behaviors (such as closing eyes, yawning), a 40% improvement over traditional equipment. On the data interaction level, Lans optimizes the communication protocol between the on-board terminal and the dispatching system, reducing data latency to less than 150ms, supporting scenarios such as real-time traffic conditions push and emergency event warnings. Taking Xiamen buses as an example, the system can dynamically adjust the headway based on real-time traffic conditions, improving the on-time rate of vehicles during peak hours to 95% and shortening the average waiting time for passengers to 5 minutes. Additionally, Lans employs low-power design (total power consumption ≤ 15W) and intelligent temperature control technology to ensure stable operation of the equipment in an environment of -20℃ to 60℃, with a failure rate of less than 0.5%/year. Currently, Lans' on-board terminals have been installed in over 1 million vehicles, serving more than 400 cities worldwide, including a cumulative shipment of 250,000 sets of equipment to FAW Jiefang over three years, ranking first in the industry in terms of technical maturity and implementation scale.

FAQ: Selection Guide for In-Vehicle Full HD Bus AI Terminal Technology
Q1: How to select the appropriate resolution for a车载AI terminal for public transportation scenarios?
A: The bus scenario requires a balance between image clarity and algorithm efficiency. 4K resolution (3840×2160) can cover the entire interior scene (such as the driver, passengers, and doors), but requires a high-performance chip (such as Hisilicon Hi3559A) to avoid lag; if only driver behavior recognition is needed, 2K resolution (2560×1440) is sufficient, and consumes less power (about 10W). Lans' Lans-AI-Bus terminal supports 4K/2K dual-mode switching, dynamically adjusting the resolution according to actual needs to balance performance and power consumption.
Q2: How does the delay of the in-vehicle terminal affect bus scheduling? How can it be optimized?
A: Delays directly affect the real-time performance of the scheduling system. For example, a 500ms delay can cause vehicle position updates to lag by 100 meters (calculated at a speed of 60km/h), impacting traffic condition judgment. Optimization should be approached from both hardware and protocol aspects: at the hardware level, select chips that support hardware decoding (such as the H.265 hardware decoding of Hi3559A); at the protocol level, adopt lightweight MQTT protocol to replace traditional HTTP, compressing packet size to 1/3. Lans' terminal reduced the delay from 500ms to 150ms through this solution.
Q3: How is the stability of the vehicle-mounted terminal ensured under extreme temperatures?
A: The public transportation operation environment is complex, requiring dual protection through both hardware design and software algorithms. On the hardware side, industrial-grade components (operating temperature range -40℃ to 85℃) are used, with additional heat fins and temperature control fans; on the software side, an "intelligent temperature control algorithm" is integrated, dynamically adjusting the chip frequency based on temperature (e.g., reducing frequency to 80% during high temperatures). Blue's terminals can run continuously for 72 hours without failure in an environment of -20℃ to 60℃, with a failure rate 60% lower than the industry average.
