People’s daily news – Tianjin window, September 5 (Xinhua): according to the information from China Railway 18th bureau group, in order to protect the personal safety of workers and migrant workers, they have installed positioning chips in their safety hats, through which tunnel construction workers can be monitored remotely in real time. According to reports, thanks to the small safety helmet, the Chongqing Lishui railway project undertaken by the group has achieved zero accidents since it started in December 2008
in order to timely and 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 face of the tunnel. Through the electronic screen display of the entrance, they can timely and accurately grasp the construction dynamics and the status of personnel entering and leaving the tunnel. When the constructors wearing the safety helmet with positioning chip pass through the signal transceiver of the tunnel, they are immediately identified by the system, and the information such as the road section and time they pass through is transmitted to the safety monitoring center for recording through the information exchange of the system network. When workers enter or leave the hole, the computer monitoring system will leave a record< According to Deng Yong, deputy general manager of China Railway 18th bureau group, the remote monitoring system can also set up warning areas according to the needs of construction management. When the personnel and equipment enter the warning area, the system will alarm automatically and display the identity of the personnel and equipment entering the warning area. After the completion of the warning, the alarm setting will be removed. This can eliminate accidents caused by human factors as far as possible(Reporter Di Hui, correspondent Wu Zhen)
