1. Project background
In recent years, my country’s highway and railway construction has developed vigorously. The national “Twelfth Five-Year” plan clearly pointed out that 30,000 kilometers of railways and 35,000 kilometers of expressways will be built in five years, most of which belong to the development of the central and western regions. Geographic location and other factors, the construction of bridges and tunnels occupies a large share. For the safety issues during construction, especially for tunnels, the safety issues during construction are the top priority.
At present, our country’s tunnel safety management technology is not perfect, the attention to safety has just started, the methods, measures, and management methods for identifying and dealing with dangers are relatively outdated, the lack of scientific safety management is serious, and the frequency of accidents is still eye-catching. . In addition to working with owners, design and monitoring units and other parties to formulate normalized emergency plans, how to prevent or reduce the hazards of accidents through more efficient and scientific means is the key issue we are facing.
2. Demand analysis
The tunnel industry is an industry with frequent accidents because of the particularity and complexity of the 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, the company has launched a smart tunnel-tunnel security management system that uses advanced RFID long-distance radio frequency identification technology in the field of Internet of Things, and integrates high-tech in many fields such as sensing technology, video technology, and multimedia display technology:
1. Realize personnel entry and exit automatic registration/location management—replace the original system of entering and exiting tunnels; (including daily management of personnel information, entry and exit records, location 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 counting, etc.;
3. Monitoring and recording of dangerous gases in tunnels, alarms for exceeding thresholds, etc.;
4. Real-time voice communication inside and outside the tunnel, making the communication faster and more convenient;
5. 24-hour video surveillance, can realize 1 month historical record storage, check at any time;
6. LED screen display or TV wall display, the display is more vivid 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 under construction.

Four, 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
Tunnel personnel entry and exit without card alarm system, which can realize the monitoring of tunnel personnel entering and exiting without card personnel
Tunnel voice communication system can realize timely voice communication inside and outside the tunnel, which is convenient and quick
