China Railway Eighteenth Bureau: Safety helmet mounted positioning chip real-time monitoring of tunnel construction security

Brief content: It was learned from the China Railway Eighteenth Group that in order to protect the personal safety of employees and migrant workers, they installed a positioning chip in the helmet, and through the positioning of the chip, the tunnel construction personnel could perform real-time remote monitoring. According to briefings, thanks to a small helmet, the profit-making railroad project under construction by the group has achieved zero safety accidents since it started in December 2008.

People's Daily, Tianjin, China, September 5: According to the China Railway 18th Group, in order to protect the personal safety of employees and migrant workers, they installed positioning chips in their helmets. Through the positioning of the chips, the tunnel construction personnel can remotely perform real-time remote monitoring. monitor. According to briefings, thanks to a small helmet, the profit-making railroad project under construction by the group has achieved zero safety accidents since it started in December 2008.

In order to dynamically grasp the number of construction personnel entering and leaving the tunnel and the construction position, the headquarters purchased a real-time remote monitoring system. They installed video probes at the entrance and the face of the tunnel, and displayed the electronic screen on the opening to accurately and accurately grasp the construction within the tunnel. Dynamic and in-out personnel status. When a construction personnel wearing a positioning chip safety helmet passes through the signal transceiver of the tunnel, it is immediately recognized by the system, and through the information exchange of the system network, the information such as the road section and time passed by this person is transmitted to the safety monitoring center for recording. Workers enter holes or exit holes, and the computer monitoring system will leave records.

According to Deng Yong, deputy general manager of the China Railway Eighteenth Group, the remote monitoring system can also set up an alert area according to the needs of construction management. When personnel and equipment enter the alert area, the system automatically alarms and displays the identity of the personnel and equipment entering the alert area. After the alert is completed, the alarm setting is released. This can eliminate accidents caused by human factors as much as possible. (Reporter Di Hui correspondent Wu Zhen)
