Application of Security Products in Natural Disasters

Natural disasters and man-made disasters cannot be avoided. Although the strength of science and technology is strong, it will not reach the outbreak of a disaster. What we can do is to make timely advance warnings and preventions before disasters occur, do a good job of defense and post-disaster repairs, and minimize losses as much as possible. This article briefly describes the various effects of security products before disasters.

The Application of Security Products and Technology in Earthquake Relief The Wenchuan earthquake once again allowed modern people to see the devastating human beings as the first earthquake in the disaster. The Earth is an active body. Every year, hundreds of earthquakes occur around the globe. Security products play a significant role in the post-earthquake protection. Security warning before the earthquake, video surveillance during earthquake rescue, life exploration, and telemedicine in personnel rescue. Security is not only a security guarantee but also a psychological comfort.

The alarm system before the earthquake warning before the earthquake set aside time for the parties to dispose of. When the earthquake occurs, the time is short and the intensity is high. The security product can be used as an early warning mechanism product for individuals or business units. Raise people's vigilance before the earthquake so that they can safely withdraw from the disaster area at the first time.

In addition, through video surveillance screens, seismologists are provided with more direct on-site images to provide intuitionistic evidence and data for future statistics and analysis of seismic data.

The epicentre of life detection in the face of ongoing disasters around us. We hope that more equipment will help search and rescue personnel to quickly, accurately and safely detect survivors who are still in danger. This will save precious time for the rescue work and reduce the number of disasters. As soon as possible, the loss is organized and returned to normal. The use of life detectors and thermal imaging cameras in the rescue allows rescue workers to detect signs of life and understand the condition of the wounded in an inaccessible and unpredictable natural environment so that emergency personnel can make quick decisions.

After the earthquake, the terrain after the long-range medical disaster is complex. Some seriously injured patients are not suitable for long-distance treatment. They can only take time to heal on the spot. However, with limited medical resources, remote medical assistance can solve a lot of problems. .

Telemedicine uses computers, communications, medical technology and equipment to realize remote, “face-to-face” consultations between experts and patients, experts, and medical personnel through long-distance transmission of data, text, voice, and image data. Telemedicine is not only a medical or clinical problem, but also includes various issues such as communication networks and databases, and it is necessary to integrate them into network systems.

In addition, the post-earthquake after-quake rescue is a major issue that affects human life. At present, many post-earthquake rescue operations are often blocked by crowded traffic and rescue vehicles, delaying the best opportunity to save people. Intelligent transportation products can help the commanding department to monitor the vehicle information at each intersection in real time, arrange the corresponding vehicle control work in time, and let the rescue personnel arrive at the scene in time to implement the rescue.

Modern lightning protection has entered a new phase of integrated mine protection projects. Summer is a season in which natural disasters occur frequently. In particular, lightning, lightning and wounding incidents and the economic losses caused by thunder and lightning are even more serious. Especially concentrated in Guangdong, where the economy is developing rapidly, these places have become the most frequent areas for lightning in China due to the relatively low atmospheric location.

In addition, the widespread use of electronic devices is another reason for frequent lightning. With the rapid development of electronic technology and the popularity of the Internet, humans are increasingly relying on electronic devices, especially computer systems. However, due to the miniaturization and high integration of electronic components, the withstand voltage capability of various types of electronic devices has been reduced. As a result, incidents of lightning and overvoltage destruction have been on the rise, posing a serious threat to the safe operation of devices and networks. According to statistics, the losses caused by lightning damage in the world are as high as one billion US dollars each year.

In today's information society, a large number of electronic devices, especially electronic computer technology and microwave communication technology are becoming more and more popular. The harm caused by lightning induced by lightning has increased significantly. Lightning protection by lightning rods alone is far from meeting the actual requirements for lightning protection of electronic, communications, and microelectronic devices. . In order to meet this need, lightning protection in recent years has evolved from simple lightning rod protection to direct lightning strikes to a new stage of comprehensive lightning protection. The lightning protection project is a systematic project. It includes direct lightning protection, equipotential bonding measures, shielding measures, standardized integrated wiring, lightning induced lightning and lightning lemp protection, and perfect grounding and grounding systems. Partly composed. In a complete lightning protection system engineering (especially the lightning protection of microelectronic equipment) are indispensable. If one aspect is not considered properly, not only will it not achieve lightning protection, but it may also lead to damage to the equipment.

Responding to the stormy mudslide monitoring cameras storming in recent days both in the south and the north have been severely hit by heavy rain, and there have also been deaths in many places. The heavy rains have repeatedly tested the strength of flood control in some areas. It also tests the strength of a city’s surveillance cameras and other real-time monitoring reports.

With the popularization of video surveillance technology, video surveillance has become an important component in the flood protection system and plays an irreplaceable role in the monitoring of disasters. Through video surveillance, water monitoring is monitored in real time in key areas. Video surveillance has become an integral part of the nerve center in the process of flood prevention and flood control. Through monitoring screens, staff can watch real-time changes in the rainy season and encounter flood disasters. Early warnings can be made in time to minimize disasters. The monitoring and command center of the Urban Facilities Administration Bureau is the most crucial nerve center in the process of flood prevention and flood prevention. Through real-time monitoring of various monitoring points in urban areas through large screens, it can be seen through the screen that there is no accumulation of water on the roads that are prone to water accumulation. At the same time, the situation of traffic roads is monitored at the same time, whether there is traffic congestion due to accumulated water.

When heavy rainfall causes traffic disruption, in order to prevent the occurrence of local traffic congestion, it will strengthen the contact with the meteorological department, grasp the weather changes in time, and use Skynet video surveillance to discover that tree dumping and traffic isolation facilities are caused by bad weather. Loss, signal failures, power failures, underpass tunnels, overpasses, etc., promptly informed the garden, urban management, power, water and other functional departments to actively dispose of, quickly rule out road dangers, eliminate traffic safety hazards, and restore road traffic order. Through the real-time release of dynamic traffic information, the traveler is induced to choose a reasonable route for travel, to balance the flow of the road network, and to alleviate the frequent and regular traffic congestion in key areas and key sections.

The application of remote sensing technology in the construction of the flood and water disaster prevention and control system is amidst various natural disasters. Flood and waterlogging disasters are one of the major disasters that threaten China's national economy and people's lives and property.

The occurrence of floods and floods generally has abrupt characteristics. To carry out early warning and forecasting of flood disasters, disaster relief, and post-disaster reconstruction requires timely, accurate and reliable collection and feedback of flood-related disasters. However, traditional information acquisition methods, processes and levels based on human-made information have been difficult to meet flood control requirements. The remote sensing technology developed in the 1960s has been widely used in the study of floods and other natural disasters because of its advantages of large observation scope, large amount of information acquisition, high speed, good real-time performance, and strong dynamics. After thirty to forty years of exploration, application and practice, it has gradually formed a remote sensing application field and method throughout the pre-disaster, disaster and post-disaster processes.

Remote sensing technology has great application potential in pre-disaster warning and forecasting of floods, disaster monitoring and damage assessment in disasters, and arrangements for disaster relief, disaster reduction and reconstruction. The combination of remote sensing and GIS, in particular, will help solve the two core issues of flood and disaster reduction, namely the rapid and accurate prediction of disaster events, and the rapid assessment of the location, extent and intensity of disasters caused by disaster events.
