Project Overview

In 2025, the BOD series industrial-grade industrial frequency UPS power supply from Bodiantong was officially selected procurement project of the Qingxing Expressway in Guizhou Province. It provides comprehensive uninterrupted power supply protection for substations, bridge monitoring systems, tunnel supporting equipment, toll station industtrol systems, and emergency lighting facilities along the entire 71-kilometer expressway. As a component of the 'Longitudinal Line 6' of Guizhoce's expressway network, the Qingxing Expressway connects the Shanghai-Kunming Expressway and the Shanwei-Kunming Expressway, serving as a vital inter-provincialsouthwestern Guizhou region. The Bodiantong UPS power supply establishes a solid core defense for electrical safety, safeguarding the safe passage and operational efficiency of this major transporta artery, and facilitating regional economic integration.

Core Customer Requirements

(1) 7×24-hour uninterrupted power supply to eliminate safety hazards caused by municipal power anomalies and grid flutions in karst mountainous areas, ensuring the normal operation of core monitoring equipment and toll systems for bridges and tunnels, safeguarding highway traffic safety, and meeting the requirements of smart transportation o maintenance.

(2) Adapt to the complex outdoor environment of the Qingxing Expressway, characterized by steep mountains and overlapping peaks, resisting grid interference, temperature fluctuations, and prolonged riny weather. It provides clean power to protect the safe and stable operation of precision monitoring and industrial control equipment, suitable for high bridge-to-tunnel ratios.

(3) Supports intelligent remot monitoring, adapting to the dispersed layout of multiple highway sites and the extensive maintenance scope. It reduces manual inspection costs, improves fault response and handling efficiency, and meets the needs for the intellit upgrade of highway operation management systems.

(4) Features industrial-grade protection, with resistance to high and low temperatures, vibration, moisture, and salt spray. It offers reliable quality and  after-sales support, strictly complying with transportation industry maintenance standards and the complex outdoor working conditions of the Qingxing Expressway, suitable for long-term stabl

Customized Solutions

Combining the characteristics of the Qingxing Expressway's karst mountain sections, the scenario of dispersed power usage across mutiple sites, and core requirements, Bodiantong has customized a tailored solution with the following core advantages:

(1) Precise Sizing: Based on the varying power loads of dift sites such as bridges, tunnels, and toll stations on the Qingxing Expressway, equipment power is configured rationally to cover all power needs and reserve expansion space. This fully cith relevant traffic industry standards and expressway operation and maintenance norms, adapting to its four-lane bidirectional operational scale.

(2) Zero-Interruption Assuranceing a double-conversion topology to achieve zero-millisecond switching and pure sine wave output, it effectively isolates issues such as mountainous grid interference and voltage fluctuations. This ensures seamless and staboperation of core equipment like monitoring and toll collection systems, eliminating traffic hazards caused by power outages and safeguarding the safety of the regional transportation hub.

(3) Intelligent Maintenanquipped with an LCD touch operation interface and a remote monitoring system, it allows for real-time monitoring of equipment status and automatic fault alarms. Supporting remote troubleshooting and parameter debugging, it significanimproves the efficiency of decentralized maintenance across multiple sites, reduces labor costs, and adapts to the scenario of intelligent expressway maintenance.

(4) Industrial Protection: The equipment PCB board coated with a three-proofing paint process, offering excellent moisture-proof, salt-fog resistant, and anti-vibration performance. With wide temperature adaptability, it suits the complex outdoor ennment of the Qingxing Expressway, featuring high and low temperatures and frequent rain. It is energy-saving and meets electromagnetic compatibility requirements, adapting to long-term outdoor operation in areas with dense and tunnels.

Project Outcomes

Upon implementation, the project achieved zero power outages for core electrical equipment on the Qingxing Expressway, avoiding safety hazards and operational losses caused by power anomalies. Intelligent O&M significantly reduced inspection workload and saved manpower, while clean power extended equipment lifespan and lowered maintenance costs. This provides robust power support for efficient exressway O&M, smart transportation construction, and regional traffic integration, facilitating the Qingxing Expressway's full utilization as an inter-provincial linkage channel.
