[Real-time] Hefei Rail Transit Project Pilot Hard Hat "Two-dimensional Code" Technology

This year, the construction volume of rail transit in Hefei will hit a new high. How can the quality of the project be effectively improved in the face of complicated procedures and massive construction workers? The reporter learned from the Hefei Urban-rural Construction Committee that it is starting from the 3rd line to start a full-scale pilot two-dimensional code technology, through the scan code to achieve the dynamic management of site personnel and equipment, to ensure the construction of the problem. In the future, it is planned to fully promote it on the 4th and 5th lines and the follow-up rail transit lines.

In 2017, Hefei's urban rail transit construction entered a period of rapid development, and strived to start line 2 operations in October. The entire line of line 3 entered the tunnel shield construction stage, and line 4 and line 5 opened the curtain for comprehensive construction.

The construction of rail transit that is in full swing has also brought a lot of management work. The constructors, constructors, and supervisors need to understand the dynamic information of personnel, project progress, construction progress of key parts, safety and quality control, and maintenance and management of on-site equipment. All of these use traditional management methods and are time-consuming and labor-intensive. Difficult to record, difficult to query, difficult to statistics problems.

To innovate and effectively improve management of urban rail transit construction in Hefei, the urban and rural construction committee rail transportation construction project quality and safety supervision station applies two-dimensional code technology to rail transit quality and safety management work. At present, safety technology training and personnel dynamic management Large-scale equipment management, temporary power management, structural inspection, deep pit monitoring, etc. achieved outstanding results.

In terms of the application of two-dimensional code technology in personnel dynamic management, in the past, people on the construction site used the production badges and entered the badges. However, during the construction process, the badges were easily damaged and easily lost. In addition, the anti-counterfeit badge has a low function and the production cost is high. Now stick the worker information two-dimensional code on the helmet and scan the code to enter the site. It can display the identity information such as sex, age, blood type and type of work of the workers, and realize the binding of the two-dimensional code with the helmet. The helmet with no two-dimensional code is not allowed. Approach.

At present, there are nearly 40 rail transit projects in the city, and a total of more than 5,000 two-dimensional codes have been set up. The city's orbital stations have been carefully planned. At this stage, the two-dimensional code technology is mainly used in the construction and management of the No. 3 line project. The line and line 5 and the subsequent construction of the rail transit line were fully promoted.
