Replacing Routine Inspections with Mobile QR Code Scanning: How Renzhuang Mine Implements "Special Management" for Special Equipment

Original: https://cli.im/article/detail/1855

With the sustained, rapid, and healthy development of the mine, the types, quantity, and scale of use of special equipment continue to expand. To ensure the daily management and safe operation of special equipment, Renzhuang Mine has implemented "special management" for special equipment. By adopting a management method using WeChat QR code scanning, the implementation and application of an information system for special equipment have been achieved.

How can mobile QR code scanning replace routine inspections, making special equipment inspection work safer, more convenient, and more reliable, while also avoiding issues such as false inspections and missed inspections?

This question lingered in the mind of Wang Wei, an employee of the Electromechanical Power Department.

After receiving approval from relevant leaders for this simple idea, Wang Wei took action. During the Spring Festival holiday, he developed a web module, inputting special equipment information, inspection content, and requirements into the backend management system. Each device added generated a corresponding QR code.

After 28 days of effort and 21 days of practical testing, the system was trialed on February 7 and officially launched on March 1, receiving unanimous recognition and praise from all departments and teams.

By utilizing the GPS positioning feature of mobile phones, the system not only effectively prevents false and missed inspections but also accurately reflects the "health status" of the equipment. This allows staff to understand the situation at a glance, simplifies work steps, and eliminates paper waste.

Wang Wei said: "Each device corresponds to a QR code. Scanning the code with WeChat reveals all the device's parameters, serial number, responsible personnel, and other information. There's no need to sift through documents when checking details. Dynamic records such as spot checks, repairs, and maintenance added during use are also saved, gradually forming a dynamic archive of the equipment, which is very convenient for management."

During equipment inspections, if any abnormalities are found, submitting a fault report form automatically notifies the relevant responsible personnel. Additionally, inspectors can manually select to notify collaborative maintenance personnel. After repairs, relevant personnel can add handling descriptions to the abnormal record, including text, images, and forms, and can also notify others to review, forming a closed loop. Subsequently, the entire repair and maintenance process is archived for targeted fault analysis and preventive measures.

After the QR code management system was launched, managers and operators can view planned reports on their mobile devices at any time, monitor the inspection status of all equipment, and check completed inspections, pending tasks, and upcoming deadlines. They also receive reminders for approaching deadlines, enabling quick task completion, ensuring regular equipment inspections and maintenance, and avoiding missed inspections.

The application of QR codes in the special equipment industry of coal mines is a first for Renzhuang Mine. By dynamically managing the equipment usage cycle, it is possible to understand each device's journey during its effective use, including the actual duration of use, the number of repairs, and parts replacements. This helps better leverage the potential of special equipment and extend its service life.
