1. Project Background
In recent years, my country’s highway and railway construction has been booming. The national “Twelfth Five-Year Plan” has clearly pointed out that 30,000 kilometers of railways and 35,000 kilometers of expressways will be built in 5 years, most of which belong to the development of the central and western regions. Geographical location and other factors, among which the construction of bridges and tunnels occupies a large share. Safety issues during construction, especially tunnels, are of the utmost importance.
At present, my country’s tunnel safety management technology is not perfect, the emphasis on safety has just started, the methods, measures and management methods for identifying and dealing with hazards are relatively outdated, scientific safety management is lacking seriously, and the frequency of accidents is still eye-catching. . In addition to formulating a normalized emergency plan with the owners, design and monitoring units and other parties, how to prevent or reduce the harm of accidents through more efficient and scientific means is the key problem we face and need to solve.
With years of accumulation, the first set of “Tunnel Personnel Safety Management (Attendance and Positioning) System” was developed in 2009, and it was promoted nationwide, especially in civil construction projects. Nationwide, in the construction of highway tunnels, railway tunnels, urban subways, and various construction sites, automatic attendance of staff, comprehensive positioning management, and the combination with traditional video linkage make this system popular in the industry. With the love and support of our customers, so far, it has been successfully applied in major civil infrastructure construction units in China.
2. Demand analysis
The tunnel industry is an industry with many accidents and frequent accidents because of the particularity and complexity of construction, and the occurrence of tunnel accidents is often sudden and unpredictable. Once an accident occurs, the consequences are usually more serious. Combined with the market As well as user feedback, I introduced an advancedRFIDLong-distance radio frequency identification technology, and integrates sensor technology, video technology, multimedia display technology and other high-tech smart tunnel-tunnel safety management system:
1. Realize the automatic registration/location management of personnel entry and exit—replace the original system of entering and exiting the tunnel; (including daily management of personnel information, entry and exit records, positioning information, data analysis, storage, report printing, etc.)
2. Realize the automatic management of vehicle entry and exit, including entry and exit registration, entry and exit count, etc.;
3. Tunnel dangerous gas monitoring, recording, over-threshold alarm, etc.;
4. Real-time communication of voice inside and outside the tunnel, the communication is faster and more convenient;
5. 24-hour video surveillance, which can realize 1-month historical record storage and view at any time;
6. LED screen display or TV wall display, the display is more image and professional;
7. Remote access management, real-time and anywhere, as long as there is a network, you can view the safety information of the current tunnel construction.

Fourth, the system application extension
The gas tunnel intelligent detection system can realize the gas monitoring function of the gas tunnel, which is timely, safe and effective.
The alarm system for tunnel personnel entering and leaving without card can realize the monitoring of tunnel personnel entering and leaving without card
Tunnel voice communication system, which can realize real-time voice communication inside and outside the tunnel, which is convenient and fast
Five, the successful cases are as follows:
