QR Codes Enable Electronic Management at Xinneng Group Project Sites

Original: https://cli.im/article/detail/1974

We trialed CaoLiao QR codes on an engineering project in Hotan, Xinjiang as early as 2019. After the trial, the overall results were very satisfactory. We have now extended the application of QR codes from the construction process to operational inspections post-commissioning.

Before using QR codes, we struggled to find effective tools for on-site management at our power projects, leading to numerous management inconveniences:

1. Difficulty identifying personnel on-site made management challenging, as it was unclear if individuals were properly registered.
2. Test qualification labels on safety tools were prone to damage or detachment. Discovery during inspections could lead to penalties or even work stoppages for rectification.
3. Documents like work plans and technical disclosures often comprised dozens or even hundreds of pages, making them cumbersome to carry.
4. Delayed handover of technical documentation upon project commissioning hindered equipment maintenance by operational units and complicated emergency repairs by maintenance teams needing quick access to information.
5. The vast variety and quantity of power equipment, coupled with extensive maintenance manuals and specifications, required borrowing technical documents from the archives before periodic on-site maintenance or inspections. Transporting and referencing these voluminous materials was highly inconvenient.

Now, using QR codes, we have achieved electronic application and management of archival data for power supply equipment and facilities on-site. Additionally, encryption and permission settings protect detailed information and privacy related to enterprises, institutions, and residents, ensuring data security by restricting access to authorized personnel only.

Personnel Information QR Codes

Personnel information is compiled into QR codes, printed on adhesive labels, cut out, and affixed to safety helmets. Scanning the code instantly reveals individual details and qualification status. QR codes can also be integrated with access passes to log personnel entry and exit records.

Safety Tools QR Codes

Basic tool information, inspection and usage notes, and instructional videos are batch-generated into QR codes. Printed on standard A4 paper, cut out, and sealed with transparent tape on safety harnesses, voltage testers, etc., these codes allow quick access to safety tool management standards and enable the logging of routine inspection records, ensuring traceability for daily checks. Concerns about penalties due to damaged labels during inspections have vanished, and inspectors highly approve of this method.

Engineering Project Management

Project information, construction plans, drawings, and completion documents are converted into QR codes and attached to commissioned equipment. Scanning provides immediate access to all relevant data, eliminating the need to transport large volumes of paper documents that are easily lost or damaged. For completed projects, scanning reveals all necessary information, facilitating joint on-site acceptance inspections and subsequent operation and maintenance.
