In order to enhance the awareness of disaster risk prevention in the whole society and popularize the knowledge of disaster prevention and mitigation for the whole people, on May 12, the Garden and Forestry Bureau of Qingdao City, Shandong Province invited a number of young reporters to carry out forest fire prevention science popularization activities. "How can we protect the trees and prevent fires in the mountains? The mountain forest area is vast, how to monitor and find the source of fire? In the event of a fire emergency, how can you respond quickly to extinguish a wildfire? Duan Yichen, a young reporter, came to Fushan with these questions in mind, looking for answers to these questions in the activities of the Disaster Prevention and Mitigation Day.
Science and technology empower forest defense
When the reporter walked into the Fushan Forest Fire Prevention Video Surveillance Center, the staff was inspecting the mountain and forest areas through video surveillance: the lush pictures of the Fushan Mountains and forests were displayed on the "super large screen" of the entire wall. "With so many pictures, if there is a fire, how can we find out in the first place?" Fu Xuanbo from Shinan District Experimental Primary School raised his own questions. "The monitoring equipment set up on the floating mountain uses thermal imaging and pyrotechnic recognition algorithms to monitor around the clock, day and night." Captain Wang of the Fushan Forest Fire Prevention and Maintenance Team in Shinan District told the young reporter, "Once the temperature rises above the set threshold, the system will automatically send out an alarm and flash on the corresponding screen." We can immediately call up the screen to accurately locate and notify the forest defense team members who are patrolling through the mobile terminal of the forest fire prevention system. "It's high-tech! This is like a huge net, controlling every grass and tree, one person and one vehicle in the forest, and like countless pairs of snooping eyes, always monitoring the wind and grass, smoke and fire. Everyone sighed. Will there be blind spots in monitoring? What to do where the camera can't see? Wang Junhao of Qingdao New Century School asked. That's a good question! We have watchtowers. Moreover, there are firefighters in each area of Fushan, and the grid real-name management is implemented. If a fire is found in the lookout or monitoring room, it can be contacted by the ground personnel in time, and the firefighters can quickly assemble the team. The firefighters are equipped with wind-powered fire extinguishers, a full set of fireproof clothing, walkie-talkies and other special equipment, and patrol 24 hours a day, in order to patrol the forest area in all directions without dead ends and not let go of any fire hazards. ”
Forest fire prevention "artifact"
Build a solid forest fire safety barrier
"What do so many small white squares represent?" The young reporter pointed to the sand table model in the command center and asked. Captain Wang patiently answered every reporter's question: "This is a water bladder, and each water bladder stores 8 tons of water. The fire water tank has a valve that can be connected to the pipe to extinguish the fire nearby. These different icons represent fire escapes, watchtowers, fire water bladders, fire hydrants and other positioning information, which are all forest fire prevention infrastructure construction, key geographical indications, and the distribution of water sources throughout Fushan. Captain Wang said. Outside, the small forest fire truck, which looks like an off-road vehicle, attracted the attention of the children, and the young reporters got into the cab to experience the feeling of a little fire guard. The small forest fire truck can easily shuttle through the forest area, carrying people and equipment is no problem, and the water pipes and waterproof belts on the front and roof of the car can send the water from the fire hydrant halfway up the mountain to the top of the mountain. There are two dry powder fire extinguishers on both sides of the front of the car for ignition of all kinds of sudden fires. "It's a wind-powered fire extinguisher, which uses gasoline as fuel and uses high-velocity air currents to extinguish fires. It's like blowing out a candle in one breath and letting a strong wind extinguish the fire. Captain Wang introduced the fire-fighting equipment in easy-to-understand language, "This sprayer is the equipment for extinguishing embers, and it will spray mist droplets when loaded with water; This one looks like a mop, we all call it the No. 2 tool, don't look at him inconspicuous, it is an effective tool to clean up the embers. Hearing Captain Wang's introduction, the little reporter curiously touched his hands and studied what kind of material the black strip tied to the head of the wooden stick was. Lifting the fire extinguisher, unplugging the safety bolt, holding the catheter, and pressing down the handle are the four steps to using a fire extinguisher. It's easy to memorize the words lifting, pulling, gripping, and pressing. Although we can often see fire extinguishers, but most of them have never been used, I hope that through the popularization of the little reporters of the evening newspaper, everyone can really use fire extinguishers! Captain Wang said.
Guarding the lucid waters and lush mountains and striving to be the little guards of forest fire prevention "immersive" experience, "zero distance" contact with forest fire prevention, the young reporters practiced in the experience, learned in the interaction, and deeply understood the severity and importance of forest fire prevention. They are determined to become little guards who popularize the knowledge of forest fire prevention, and promote the environmental protection concept of "the forest is my home, fire prevention depends on everyone, and build a beautiful home together" with classmates, friends and family, so as to maintain the beautiful "appearance" of Qingdao. At the same time, they also expressed their thoughts on building a solid forest fire safety barrier with their own observations and perspectives. Duan Yichen from Qingdao Jiading Road Primary School wrote after the event, "Different scientific and technological equipment, different firefighting equipment, but everyone has the same goal: to prevent problems before they occur and protect the green forest." In the future, I want to be a forest fire prevention propagandist and pass on the knowledge of forest fire prevention to more people. Protecting mountains and forests is everyone's responsibility! Qiao Kaixiang of Jinmen Road Primary School said, "Forest fire prevention should focus on prevention. For the safety of people's lives and property, smoking is prohibited in forest areas, and fires are prohibited. As a young reporter, I want to share the knowledge of forest fire safety with our classmates, so that more people can get closer to and understand forest fire prevention, and everyone can prevent and reduce disasters together. Reporter's note: Wang Junhao (Qingdao New Century School): May 12 is the National Disaster Prevention and Mitigation Day every year, reminding people to pay attention to disaster prevention and reduction. On this year's Disaster Prevention and Mitigation Day, I followed the reporter of the evening newspaper to Fushan Forest Park and learned about forest fire prevention together. "Lucid waters and lush mountains are invaluable assets." To protect the safety of forests, we start from me, and together we make our own contribution to the protection of green mountains and clear waters. Yi Qingran (Qingdao Tong'an Road Primary School): I live at the foot of Fushan, and I usually like to play with my parents or classmates on the mountain. Today, I followed the Qingdao Evening News reporter group to the Shinan District Plant Protection Center, which gave me a deeper understanding of this sentence. It turns out that there are so many people silently guarding this beautiful floating mountain, for our green home, I also want to be a guardian, do a good job in fire prevention publicity, and protect this green mountain and clear water. Duan Yichen (Qingdao Jiading Road Primary School): The first thing we visited was the monitoring room. As soon as you enter the door, an entire wall that catches your eye is a surveillance screen composed of blocks of lattices. Captain Wang said that there are a total of 96 cameras and 218 pictures here, as if it is the heart of the mountains and forests in Shinan District, and the basic situation of Fushan can be understood from the monitoring screens. If a fire is found, the screen flashes an alarm according to the thermal imaging temperature sensing. With the rapid development of technology, today's surveillance can not only record video, but also rotate 360 degrees to identify high temperature areas. Fu Xuanbo (Qingdao Shinan District Experimental Primary School): I followed the little reporter of the evening newspaper to the Fushan Forest Fire Prevention Video Surveillance Center to know that the current forest fire prevention methods are all high-tech! In addition to real-time detection of fire through monitoring, thermal imaging and other technical means, there is also a real-time face tracking system, which can determine the path of tourists into the mountain, and achieve a human-to-person fire prevention mode.
