Line 12 devaluation of “intelligent” site safety helmets to locate the constructors

Construction workers use safety helmets to swipe their cards into the gates of the construction area. Each information of the construction personnel entering the site is displayed on the display screen of the monitoring room. The handheld terminal scans the chip of the construction segment and the settlement of the ground can be instantly visible. ...Xinmin.com reporter today (10th) saw the construction of the No.11 project on the No. 12 rail line at the Longhuazhong Road Station site. As the first smart chemical industry site of the rail transit in Shanghai, the digital system has been fully promoted in the project.

Special safety helmet positioning construction personnel

“The dynamic management of people has always been a difficult point in the management of construction sites.” Xu Yunhai, project manager of the 11th project of the Shanghai Urban Construction Corporation’s rail transit line 12, told the reporter that the Longhuazhong Road Station implemented digital management of construction personnel. “The secret weapon” is Hard hat worn by construction workers."

Xinmin.com reporter saw that this kind of helmet has a special chip, which contains information such as the user’s name, ID number, contract signing, social insurance, physical examination, type of work, and operation permit. “These information and access control systems Connected, only allowed to move out of the construction site after all the above information is confirmed."

Xu Yunhai also told reporters that the chip also has a positioning function, in the monitoring room can directly reflect the location of workers, types of work, access to the construction area and the time of stay; in the underground movement process can also be captured by the reader, all-round tracking The downhole walking trajectory enables real-time positioning of personnel and facilitates safety management. “Whether the safety personnel are in place or not, and the position of the workers is clear at a glance.”

Intelligent chip monitoring land subsidence

In addition to special safety helmets, the Xinmin.com reporter saw that the construction workers at Longhuazhong Road Station are like the cargo clerk in the supermarket. The handheld handheld terminal scans the chips installed on the segment.

"In fact, we are inputting information, including the ring number, segment type, construction date, piece of certificate information, construction personnel information, roundness and grouting volume, etc." Xu Yunhai said, after information input and monitoring The center terminal performs synchronization processing and all the information can be analyzed and processed in the background. “By dynamically inputting the construction parameters at the control terminal, the dynamic information feedback and control can be ensured at all times to achieve leakage, fragmentation, axial deviation and grounding of the segment. Instant control of settling."

The reporter learned that the 11th project of Metro Line 12 is located in the Binjiang Development Zone of Xuhui District. The project mainly includes Longhua Station-Pujiang Nanpu Station Interval Tunnel and Pujiang Nanpu Station-Damuqiao Station Interval Tunnel Project. Longhua Station-Pujiang Nanpu Station is 1021 meters long, and Pujiang Nanpu Station-Damuqiao Station is a 1,220 meter long tunnel. It is expected that the range will be open at the end of this year.

In addition, after the completion of Line 12, Pujiang Nanpu Station will be renamed Longhua Middle Road Station and can be interchanged with Line 7.
