From Paper-Based to QR Code-Based Inspections: Equipping Devices with "Digital IDs"
Original article: https://cli.im/article/detail/2064
In industries such as manufacturing, energy & power, and construction, equipment inspection remains an essential workflow component. Traditional paper-based maintenance records often create information silos, requiring significant time and manpower for consolidation. Manual recording also risks inaccuracies and omissions.
Digital Transformation for Equipment Management
Ningbo Linjia Network Technology's CaoLiao QR Code team developed a QR code management system to digitize inspection records. The platform enables rapid creation of various QR codes while serving as a flexible application-building environment for operational efficiency improvement. With over 430 million users, the system treats QR codes as "digital IDs" for equipment, enabling online recording of parameters, responsible personnel, and technical documentation through forms.
During inspections, technicians scan equipment QR codes to submit findings with multimedia attachments. The system automatically alerts relevant personnel about abnormalities, allowing maintenance updates through text, images, or form submissions directly linked to each device's digital ID. This creates full lifecycle monitoring with traceable anomaly resolution.
Overcoming Connectivity Challenges in Remote Areas
Field efficiency became critical when a safety director at China State Construction Engineering Corporation reported persistent issues: "Our inspectors in suburban construction zones struggle with slow media uploads, forcing them to wait onsite and delay subsequent checks."
CaoLiao's analysis revealed core challenges in remote inspection scenarios:
- Unstable network connections causing blank pages/slow loading
- Prolonged media file transfer times
- Risk of critical data loss due to failed uploads
Huawei Cloud CDN Accelerates QR Code Performance
Partnering with Huawei Cloud Ningbo Innovation Hub, CaoLiao implemented a CDN-powered solution delivering:
- Edge Node Distribution: Media-heavy content gets cached at regional CDN nodes, reducing origin server load by 30% during peak times while minimizing bandwidth costs.
- Multi-level Caching: Proprietary AICache technology with SSD-accelerated storage achieves 99% cache hit rate, cutting average access latency by 30ms nationwide.
- Anti-leech Protection: Referrer whitelisting and URL authentication prevent unauthorized resource access.
Huawei Cloud's global infrastructure - 2,800+ nodes across six continents with 150Tbps+ bandwidth - ensures 99.9% service availability. "The CDN solution significantly improved our user experience and operational efficiency," confirmed Jiang Yunhui, CaoLiao's CEO.
Broader Applications of Cloud-powered Inspections
Beyond equipment management, Huawei Cloud enables various smart inspection scenarios:
- Wearable-device integrated video conferencing for real-time remote guidance
- AI-powered grid inspections using edge computing for transmission towers and substations
As industries embrace digital transformation, Huawei Cloud continues providing secure, reliable cloud services to accelerate intelligent upgrades across manufacturing, energy, and construction sectors. Through technological innovation and ecosystem collaboration, Huawei empowers organizations to build smarter inspection workflows on its "black soil" platform for industrial IoT growth.
