Passenger flow monitoring and forest fire prevention monitoring project in a mountainous scenic spot
Combined with the deployment of visible light and thermal imaging dual-spectrum heavy-duty pan/tilts at the high points of the mountain structure, it can realize passenger flow density monitoring, fire and smoke identification and alarm, and intrusion prevention in key cultural relics areas.

Project background
This scenic spot is a national-level mountain scenic spot, receiving more than 2.6 million tourists annually. The pressure of forest protection and fire prevention coexists with the pressure of passenger flow during holidays. The management office plans to build a visual management and control network without destroying the natural landscape.
Key technology selection
| Requirements | Technical Selection | Reasons |
|---|---|---|
| Long-distance fire point identification | Thermal imaging dual-spectrum PTZ | Can penetrate smoke and identify abnormal temperature rise at night |
| No point power supply from the mains | Solar energy + lithium battery | Avoid large-scale excavation of cable trenches |
| Mountain Backhaul | Wireless backbone + existing optical fiber | Balancing cost and bandwidth |
| Lightning protection | Three-level lightning protection + grounding network rectification | High lightning failure rate in mountainous areas |
Operational results
In the first fire prevention season, the system successfully warned of 3 initial fires, and all were verified and dealt with within 20 minutes. No forest damage was caused. The holiday passenger flow warning mechanism also allows the queuing system to have a 30-minute scheduling buffer in advance.
Project difficulties
Issues that need to be addressed during project advancement
The scenic area is large, the terrain is complex, and power supply and communication are difficult
Most commanding heights have no mains power or fiber optics, so self-organized energy and networks are required.
The detection of fires in forest areas lags behind, and traditional inspections are difficult to cover
Relying on forest rangers to patrol mountains, it is difficult to identify fire spots at night
Passenger flow surges during holidays, and there is a risk of stampede
Ropeway entrances and viewing platforms are prone to instantaneous gatherings
Equipment needs to withstand high humidity, lightning and low temperature tests all year round
The outdoor environment has extremely high requirements on equipment reliability
solution
Technical and construction measures taken to address the above difficulties
Dual-spectrum heavy-duty pan/tilt deployed at 14 commanding heights
