As the weather gradually cools, the leaves on the roadside slowly begin to change color. Autumn is coming, it is a season of harvest. However, since the first day of September, the whole country has been shrouded in a subtropical high pressure, so there has been no heavy rain. With the continuous sunny weather, it is conducive to the accumulation of sugar in the fruit, but it also brings another hidden danger, that is, fire, especially forest fire.

With the continuous strengthening of our people's awareness of environmental protection and the increasing area of ​​closing mountains for afforestation and afforestation, wildfires have become one of the most threatening natural safety hazards.

Every year, the fire department of the forestry department spends a lot of effort in this area, but it still has little effect. After all, there are too many factors that can cause fires, such as natural factors, human factors, and even some accidental factors.

For example, the weather is overheated, leading to dry vegetation, and some oily and dry plants are prone to spontaneous combustion. In addition, natural factors such as lightning strikes can easily cause wildfires.

In addition, there are more human reasons, especially in remote mountainous areas. The traditional way of sweeping tombs is easy to cause fires. The fire is a cigarette butt, and picnics are also very easy to cause mountain fires.

As soon as this year's summer came, it has gotten better, and it has paid a heavy price.

The Nanshan area in the south of Anshan is the earliest virgin forest reserve in China to realize the closure of mountains for afforestation. In recent years, due to the development of tourism, several large forest parks have been developed locally in the Nanshan area, and have attracted a large number of tourists.

And this naturally brings a lot of potential safety hazards, especially the large number of tourists and the uneven quality. There have been several fires caused by the negligence of tourists. Fortunately, they were discovered in time and did not cause too much consequence. .

And this has also caused a lot of controversy. There is only one focus of attention and discussion, that is, whether tourism and environmental protection can have both.

The problem now is that tourism development has seriously affected the safety of this protected area. Whether it should be continued or not, the opinions of various parties are different.

Environmental protection departments and forestry departments naturally hope to close tourist attractions, reduce human damage to nature, and reduce risks and hidden dangers caused by human factors.

As far as the tourism sector and localities are concerned, these forest parks and tourist areas have indeed stimulated the local economy, especially these villages and towns located in mountainous areas, relying on these tourist areas to quickly get rid of poverty and become rich.

If these tourist areas and forest parks are closed, these villages and towns that were originally out of poverty may become poor again, and even cause some social problems.

Can you find a way to do both?

All parties have been exploring continuously over the years. One of the commonly used methods or the most effective method is to increase patrolling and monitoring, set up numerous fire warning observation points in these protected areas, install electronic monitoring and sensing equipment, or arrange special personnel to perform duties.

In addition, a dedicated forest fire patrol team conducts uninterrupted patrols to ensure that fire hazards can be discovered in time and eliminated in the bud.

This method has naturally achieved good results, and has successfully stored many security risks, but it also has a lot of shortcomings.

Especially in mountainous areas, the traffic is extremely stable. Some virgin forests are high and dense, and there is no road at all, so it is impossible to enter. And the Nanshan area itself is the kind of granite volcanic uplift landform, the mountain is very steep, and it is very difficult to patrol.

For this reason, 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, which can easily bring flight safety. Last year, a patrol helicopter in the reserve encountered a strong airflow in the mountains, which almost caused the tragedy of the helicopter crash.

In the end, the patrol helicopter was damaged and was forced to land in a col area, and the pilot was injured. Now this patrol helicopter does not dare to go deep, it is worth patrolling the outer area.

The protected area has also considered the use of drones for patrolling, but large drones fly at altitudes above 5,000 meters.

Although equipped with infrared optical sensors, the microclimate of the mountain stream is varied, often dense fog and thin clouds. Moreover, the mountainous areas are full of tall trees and dense vegetation, so it is difficult for infrared optical cameras to detect smaller fire spots.

When it is detected, the fire is already strong, and it will be more difficult to put out the fire, especially in this kind of dense forest area.

So in this regard, the reserve invites public bids, hoping to have a wireless monitoring system that can be placed in the entire reserve.

According to the bidding requirements, the modified system must be compact, safe, easy to install, have solar or wind energy charging functions, and be unattended for a long time. It has a keen insight into small fire spots, and has high-speed image transmission capabilities, which is convenient for the prevention and control command center to check the situation.

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 company, they got the news a long time ago and are very interested in it.

Everyone knows the value of this project. Once this project is successful, it will directly open up a huge market, not only in China, but also in the whole world.

Now forest fire has become a headache for countries all over the world, and it is also a disaster that causes the greatest harm. Therefore, if there is such a monitoring and prevention system, it will undoubtedly effectively prevent the occurrence of such major disasters.

Wu Hao and the others are interested because they have an intelligent unmanned patrol security system. The system itself has considered the diversity of tasks it can perform at the beginning of its design.

Fire prevention and control is also one of its main functions.

However, this alone is not enough, especially in a complex mountainous area like Nanshan, it is necessary to carry out targeted transformation of this system.

First of all, it is to strengthen the main force of the large intelligent unmanned patrol security system, that is, the ability of aerial patrol and warning drones to deal with complex terrain and complex climate (mountain microclimate).

As a result, the entire R\u0026D team also carried out very complicated experiments and improvement processes. Because of the relatively short distance and the fact that it is a local company, the entire project R\u0026D team went directly to Nanshan for on-site testing.

As a result, they also obtained first-hand information that others cannot obtain, especially detailed information on the microclimate in the mountains, which is conducive to their targeted improvement and optimization.

However, this alone is not enough. This is just a mobile patrol and warning system, and some fixed monitoring and warning systems and some sensors are needed to cooperate.
