Eliminate operational disruptions caused by utility power outages and voltage fluctuations, avoid risks of traffic control failures and delayed emergency response, aafeguard the safety of expressway traffic.

(2) Adapt to the complex power environments of outdoor and tunnel settings in Guizhou expressways. Resist power grid noise, surges, ianeous power outages, as well as humidity and dust interference. Output clean and stable power to ensure the precise operation of precision monitoring and toll collection equipment, meeting the high reliability andsafety power supply requirements of the transportation industry.

(3) Feature convenient operation and support for intelligent remote monitoring, adapting to the maintenance scenarios of expressways with multiple sites and wide cove. Reduce the cost of manual inspections. Enable real-time monitoring of UPS, EPS equipment status and battery health, with timely alarms for anomalies, thereby reducing maintenance pressure.

(4) Possess strong environmental adaptability and scalability, suitable for the limited installation spaces of expressway server rooms and tunnels. The products are of reliable quality with timely after-sales response, meeting power sumands during peak traffic periods, equipment upgrades, and maintenance expansions, ensuring long-term stable operation.

III. Solution
Combining the operational characteristics of Guizhou Expressway, multi-scenario power load requirements, and transportation industrstandards, a customized integrated procurement and installation solution is provided featuring Bodetong BOD Series industrial frequency UPS power supplies, supporting batteries, and EPS batteries. Key highlights includ
(1) Precisely matching the characteristics of various expressway loads, the solution selects compatible BOD Series UPS power supplies, supporting batteries, and EPS batteries, reserving reasonable expansion space.rictly complies with transportation industry power supply standards, catering to multi-scenario power needs such as monitoring, toll collection, and tunnel emergency systems, while completing professional installation and commissioning sitaneously.

(2) The UPS adopts a double-conversion online design with pure sine wave output, achieving zero-millisecond switching. Paired with high-performance batteries, it effectively ifluctuations and surges, eliminating equipment shutdowns caused by unstable power supply and ensuring the continuous operation of expressway core systems. The EPS battery precisely matches emergency power supply needs, enid emergency power startup in the event of a utility power outage.

(3) Equipped with a Chinese LCD touch operation panel and multi-interface remote monitoring functions, it allows real-time moring of UPS/EPS operating parameters and battery charge/discharge status and health. It features automatic audio-visual alarms and notification push for abnormal conditions, adapting to multi-site maintenance need expressways and reducing manual inspection workload.

(4) Featuring an industrial-grade compact design that saves installation space in server rooms and tunnels, it includes multiple protection functions such as overload, sort circuit, over-temperature, and overcharge/over-discharge protection. It is suitable for complex outdoor environments, is energy-efficient, and significantly improves the safety and stability of 

IV. Project Outcomes
1. Core power-consuming equipment and operational systems of Guizhou Expressway operated stably without any power-related dntime. Risks such as monitoring interruptions, toll collection stagnation, and delays in tunnel emergency response were effectively avoided, ensuring orderly highway traffic flow and improving O&M efficiency.

2. Int&M functions significantly reduced the workload of O&M personnel and cut down on manual inspection costs. They enabled precise monitoring and efficient maintenance of UPS, EPS equipment, and batteries, allowing for timely idification of potential hazards and ensuring the continuous stability of the power supply system.

3. Clean and stable power output, combined with the efficient power supply from high-performance batteries, effectively the service life of equipment such as highway monitoring and toll collection systems, reduced maintenance costs, and saved operational expenses for the Guizhou Regional Management Headquarters of CCCC Asset Manent.

4. The BOD series products feature strong adaptability and reliable operation, with efficient installation and commissioning. They fully meet the power supply demands for peak traffic and long-term operan of Guizhou Expressway, comply with traffic industry safety power supply standards, and have received high recognition from the O&M department of the Guizhou Regional Management Headquarters of CCCC Asset
