The safety helmet is an essential labor protection product for workers. During the construction work, the safety helmet can withstand and disperse the impact of falling objects, and protect or reduce the impact damage caused by the falling of the head in front of a high place and can save a person’s life. . Second, the helmet is still a sign. Different colors of helmets can be seen at the construction site, and the helmets worn by construction personnel, owners, and supervisors are of different colors to facilitate identification. Red, white, blue and other colored helmets also form a beautiful picture on the construction site. However, the helmets of the China Railway 18th Group’s Murray Railway Command have special “functionalities” because they have a small secret in their helmets: positioning chips. Since the commencement of work in December 2008, the headquarters has conducted real-time remote monitoring of tunnel construction personnel through positioning chips, which has achieved zero safety accidents since the start of construction and has ensured the personal safety of employees and migrant workers.

The China Railway Eighteenth Group is responsible for the construction task of a total length of 34.3 kilometers and a total investment of 1.805 billion yuan for the fifth tender section of the Wanli Railway, a key project of the Western Development. The tender is located in Shizhu County, Chongqing City. The main project volume is 7 tunnels and 5 bridges. The proportion of the bridge tunnel in the tender section is as high as 99.3%, and the geological complexity is high, including biased by layers, shallow burial, rock falling in danger, gushing water, Gas and many other unfavorable geology, including the Longevity Hill Tunnel with a total length of 13,468 meters, is the first long-term tunnel across the line, and the difficulty of construction is very limited at all levels.

In order to complete construction tasks safely, efficiently and with quality and quantity, Zhang Hailong, executive deputy commander of the headquarters, Sun Kaihua, secretary of the Party Work Committee, and Bai Junhua and Jia Baojun, project managers of the first and second companies, in addition to optimizing various construction processes during construction, always The safety management of construction personnel entering the tunnel construction is the key point. In order to dynamically grasp the number of construction personnel entering and leaving the tunnel and the construction location, the headquarters purchased a real-time remote monitoring system. The system facilities include a signal transceiver, wireless identification chip, security detection management system software, industrial control host, they are in the hole and the hand. The video probe is installed on the surface and the electronic screen display of the hole can accurately and timely grasp the construction dynamics in the tunnel and the status of personnel entering and exiting the hole.

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. As long as they enter holes or holes,

24-hour duty room computer monitoring system will be clearly displayed. This move was well received by the owners and migrant workers brothers. They affectionately call safety helmets equipped with chips as safe electronic "policemen."

Deng Yong, deputy general manager of the China Railway 18th Bureau Group, accompanied the interview and said: "The remote monitoring system can also set up an alert area according to the needs of construction management. Personnel and equipment enter the alert area, the system automatically alarms, and displays the personnel entering the alert area and The identity of the equipment, after the completion of the alert, the alarm setting is cancelled, which is very effective in guaranteeing the safety of blasting, and the management personnel can inquire about the identity, quantity, distribution and trajectory of the personnel and equipment in the construction area at any time, and can supervise and implement the important inspection personnel. Whether to conduct on-site inspections on time or on-site, or to conduct inspections and handling of various data, and to fundamentally eliminate incidents caused by human factors.

The hard hat was equipped with chips. The "Electronic Police" ensured the safety of the party. The Chinese Railways 18th Bureau Group's Winery Railway Express reported that: On January 27, 2010, 804 meters of Xinwu Tunnel became the first 500 meters or more through tunnels across the board. In the first quarter of 2010 and the first half of the credit evaluation and comprehensive assessment and labor competition, 7 construction units across the board stood out, won the first place in four positions, and was awarded the "three-three-three-creation-three-contending" labor competition mobile medal. On the one hand, it also topped the list of 29 bids under the jurisdiction of the Chengdu Railway Bureau’s Chongqing Construction Headquarters. The standardization management of the project was evaluated as a demonstration site and benchmarking site for the Chengdu Bureau of Standard Chemical Industry. Zhang Hailong, executive deputy commander of the Lili Railway of the China Railway Eighteenth Group, also won the 2009 MOR.
