At 6 p.m. on March 30th, a forest fire broke out in Li'er Village, Yalongjiang Town, Muli County, Liangshan Prefecture, Sichuan Province. The fire occurred at an altitude of around 3,800 meters. After the fire occurred, the prefectural and county-level governments immediately activated the emergency response plans and dispatched 689 people to fight the fire. On the afternoon of the 31st, while the firefighters were on their way to transfer their positions, they were suddenly caught in a sudden change of wind speed and direction, and were confronted with a sudden outbreak of the wildfire. 30 of the firefighters who were involved in the firefighting operation tragically lost their lives. A huge fire, like a hand, separated life and death wherever it swept through. The young firefighters who sacrificed their lives have left us with endless grief and sadness. We hope such tragedies will never happen again.

       A forest fire has caused us tremendous losses. While feeling sad, we also need to think about how we can prevent such tragedies from happening again? All we can do is to take preventive measures before the problem occurs.

       Forest fires are the most dangerous enemy of forests and the most terrifying disaster in forestry. They bring the most harmful and destructive consequences to forests. Forest fires not only burn large areas of forests, harm the animals within them, but also reduce the forest's reproductive capacity, cause soil infertility and damage the forest's water conservation function, and even lead to the imbalance of the ecological environment. Although the science of the world today is developing rapidly day by day, humans have still not made long-term progress in controlling forest fires.

       However, in large forest areas, establishing a complete fire prevention monitoring system using traditional wired methods is no longer sufficient. In this case, the long-distance wireless transmission equipment developed by our company is highly effective in the outdoor forest fire prevention monitoring system. Our long-distance wireless transmission equipment can achieve a transmission distance of 50-100 kilometers. Combined with the wind power complementary power supply system, it can operate normally even in areas without municipal electricity.
