As the weather gets cooler, the leaves on the roadside slowly begin to change color. Autumn is approaching, which is a harvest season.
However, since the first day of September, the whole country has been enveloped by the subtropical high pressure, so there has been no major rainfall. Although the continuous sunny weather is conducive to the accumulation of sugar in the fruits, it also brings another hidden danger, that is, fire, especially
Forest fire.
As our people's awareness of environmental protection continues to strengthen and the area of mountainous areas closed for afforestation and afforestation continues to increase, wildfires have become one of the most threatening natural security risks.
Every year, the fire department of the forestry department spends a lot of effort in this regard, but with little success. After all, there are too many factors that can cause fires, including natural factors, human factors, and even some accidental factors.
For example, overheating causes vegetation to dry out, and some oily and dry plants are prone to spontaneous combustion. Natural factors such as lightning strikes can also easily cause wildfires.
In addition, there are more human factors, especially in remote mountainous areas. The traditional way of sweeping graves can easily cause fires. Or a cigarette butt, picnic, aging equipment and lines in mountainous areas can easily cause wildfires.
Just since the beginning of summer this year, things have gotten worse, and a heavier price has been paid.
The Nanshan area in the south of Anshan is the first virgin forest reserve in China to close mountains for afforestation. In recent years, due to the development of tourism, several large-scale forest parks have been developed in the Nanshan area, attracting a large number of tourists.
Naturally, this has also brought a lot of safety risks, especially the large number of tourists and their varying quality. There have been several fires caused by the negligence of tourists. Fortunately, they were discovered in time and did not cause too big consequences.
.
This has also caused great controversy. There is only one focus of attention and discussion, and that is whether tourism and environmental protection can be balanced.
The current problem is that tourism development has seriously affected the safety of this protected area. Each party has different views on whether it should continue.
Environmental protection departments and forestry departments naturally hope to close tourist attractions to reduce human harm to nature and reduce risks and hidden dangers caused by human factors.
As for the tourism department and the local area, these forest parks and tourist areas have indeed boosted the local economy. Especially these villages and towns located in mountainous areas have quickly escaped poverty and become rich by relying on these tourist areas.
If these tourist areas and forest parks are closed, these villages and towns that have been lifted out of poverty may become poor again, and even cause some social problems.
Whether it is possible to find a solution that has both sides, all parties have been constantly exploring in recent years. One of the commonly used methods, or the most effective method, is to increase patrol monitoring and set up numerous fire warning observation points in these protected areas.
, install electronic monitoring sensing equipment, or arrange for dedicated personnel to be on duty.
And an independent and specialized forest fire patrol team conducts non-stop patrols to ensure that fire hazards can be discovered in time and eliminated in the bud.
This method has naturally achieved good results and successfully dealt with many safety hazards, but it also has major shortcomings.
Especially in mountainous areas, transportation is extremely inconvenient. Some virgin forests are high in the mountains and densely forested, and there are no roads at all, so it is impossible to enter. The Nanshan area itself is an uplifted landform of granite volcanic rock. The mountains are very steep, making patrols very difficult.
big.
To this end, the reserve not only relocated more than a dozen villages scattered in the reserve, but also mobilized helicopters to conduct patrols. However, the cost of helicopter patrols is very high, and the mountains are steep and the microclimates in the mountains are diverse, making it easy to carry out patrols.
Let’s talk about flight safety. Last year, a patrol helicopter in the reserve encountered strong air currents in the mountains, which almost caused a tragedy of crash and death.
In the end, the patrol helicopter was damaged and was forced to land in a mountainous area. The pilot was injured. Now the patrol helicopter does not dare to go deep and is only patrolling the outer areas.
The reserve has also considered using drones for patrolling, but the flying heights of large drones are above 5,000 meters.
Although it is equipped with an infrared optical sensor, the microclimate of the mountain stream is diverse, often with dense fog and thin clouds. Moreover, the mountainous areas are full of tall trees and dense vegetation, making it difficult for infrared optical cameras to detect smaller fire spots.
By the time it is detected, the fire has become very big. It will be more difficult to put out the fire, especially in such a dense forest area, it is even more difficult.
Therefore, the protected area has launched a tender for external bidding, hoping to have a wireless monitoring system that can be placed throughout the protected area.
According to the bidding requirements, the modified system must be small, safe, easy to install, have solar or wind energy charging functions, and can be left unattended for a long time. It must have keen insight into smaller fire points and have high-speed image transmission capabilities to facilitate viewing by the prevention and control command center.
Condition.
As the first intelligent fire prevention and control project, it has attracted the attention of a large number of technology companies, including Wu Hao and others.
As a local enterprise, they had received the news a long time ago and were very interested in it.
Everyone knows the value of this project. Once this project is successful, it will directly open up a huge market. There is a huge market not only in China, but also in the entire world.
Nowadays, forest fires have become a headache for countries all over the world, and they are also the most harmful disaster. Therefore, if there is such a monitoring and prevention system, it will undoubtedly effectively prevent the occurrence of such major disasters.
Wu Hao and others are interested because they have an intelligent unmanned patrol security system. The system itself was designed with the diversity of tasks it can perform in mind.
Fire prevention and control is also one of its main functions.
However, this alone is not enough, especially in complex mountainous areas like Nanshan, where the system needs to be modified in a targeted manner.
First of all, it is to strengthen the main force in the intelligent unmanned patrol security system, that is, the ability of aerial patrol and warning drones to cope with complex terrain and complex climate (mountain microclimate).
As a result, the entire R&D team also conducted a very complex experiment and improvement process. Because the distance was relatively close and it was a local company, the entire project R&D team went directly into Nanshan to conduct on-site testing.
Therefore, they also obtained first-hand information that others could not obtain, especially detailed information and data on mountain microclimates, which helped them make targeted improvements and optimizations.
However, this alone is not enough. This is just a mobile patrol warning system. It also needs some fixed monitoring and early warning systems and some sensors to cooperate.
