Thermal imaging and drone-driven emergency response equipment change
With the continuous innovation and development of video surveillance technology, video applications have achieved remarkable results in disaster prevention emergency, safe city and forest fire prevention. Under such a foundation, the use of visualization is constantly being given new value by the time. High-definition cameras and high-altitude telescopes are constantly escorting the people's safety. At the same time, as an important component of the disaster prevention and emergency industry, security thermal imaging technology and unmanned aerial vehicle equipment have become new types of emergency equipment, and have led the transformation of industrial high-tech equipment with highly-adjusted performance advantages of emergency rescue combat applications.
“The people’s lives and property are above all else, and the people’s responsibility for safety is more important than Taishan.” Making disaster prevention and emergency response work is an important embodiment of implementing the people-oriented scientific development concept, an important measure for safeguarding the fundamental interests of the people, and maintaining social harmony and stability. Important link. As countries and societies attach importance to disaster prevention and emergency work, disaster prevention emergency plans have been formulated in various places to achieve “organizational norms, effective prevention, and active response”, and to maximize the protection of people’s lives and property.
In recent years, China's emergency industry has risen rapidly and continues to develop, and it has played an important role in responding to sudden incidents. The emergency industry is an industry that provides special products and services for emergency prevention and emergency preparedness, monitoring and early warning, and disposal and rescue. To respond to the actual emergency needs of various emergencies in a timely manner and achieve a combination of air defense and technical defense, China’s emergency equipment and products are also approaching high standards of networking, intelligence, and automation, and new functions and technologies have been realized. The reforms and breakthroughs, among them, thermal imaging technology for disaster prevention and early warning of forest fires, and emergency drones for emergency accidents reconnaissance applications and disaster return transmissions have emerged as emerging technological trends and high-matching equipment in the field of disaster prevention and emergency response.
Forest fire warning application
Due to the impact of climate and climate, the first quarter of each year is the high incidence of forest fires, and new technologies and innovative products will come in handy to avoid accidents. Based on the actual situation of forest fire prevention, forest fire prevention can use the thermal imaging camera monitoring system to effectively realize the early detection and early prevention of forest fire dangers and prevent “unburned”. Therefore, forest fire protection has gradually become an important application field of thermal imaging technology.
Thermal imaging technology advantages
It is for several reasons that forest protection cannot be separated from thermal imaging technology:
1. Adapt to any lighting environment Traditional cameras rely on natural or ambient lighting to take pictures, while thermal imaging cameras do not require any light, relying on the thermal energy of the object itself can be clearly imaged. The thermal imaging camera is suitable for any lighting environment and is not affected by strong light. It can clearly detect and find the target day and night to identify camouflage and covert targets. Therefore, 24-hour day/night surveillance can be truly implemented.
2. With true cloud penetrating ability. Atmosphere, mist and dust will absorb visible light and near-line, but it is transparent to the hot lines of 3 to 5 micron (middle wave area) and 8 to 14 micron (long wave area), so traditional Cameras can hardly capture clear images in a cloud-filled environment, while thermal imaging cameras can effectively capture clear images of the atmosphere, clouds and other environments.
3. The target thermal energy distribution temperature field monitoring The thermal imaging camera can display the object temperature field, and the target surface temperature distribution that cannot be directly seen by the human eye becomes a thermal image representing the target surface temperature distribution that can be seen by human eyes. The monitoring of the temperature field can instantly detect temperature anomalies and prevent hidden dangers caused by abnormal temperature, such as fire.
4. Unique Thermal Diagnostic Capability Thermal imaging is the only diagnostic technology that can instantaneously visualize and verify thermal information. The thermal imaging camera can quantify the non-contact detected thermal energy, and can accurately measure the surface temperature of the photographed object. By analyzing the thermal energy distribution and temperature of the photographed scene, the thermal imaging camera can realize the abnormal diagnosis of the environment or the object. Tracks scenes or areas of high temperature targets, and alarms when the temperature is above a set point. 2 sudden accident emergency response applications With the opening up of the low-altitude field in China, there has been a domestic drone industry cluster and more and more applications have been applied to disaster prevention and emergency fields. At the end of May 2015, there was a huge flood disaster in Changyi Reservoir, Jingxing County, Shijiazhuang City, and all personnel quickly entered rescue and self-rescue status. On the 27th, Changyi Reservoir in Jingxing County of Shijiazhuang City organized the emergency drills for disaster prevention and reduction in Hebei province to simulate the scene of floods caused by heavy rain. It is worth mentioning that Shijiazhuang City was first used in this emergency drill. UAVs participated in the simulation of emergency rescue and fully demonstrated the theme of "science disaster reduction and legal response."
The drone in the exercise can last for up to 45 minutes and has a flight altitude of 1,500 meters. It also has high-definition video camera and level 6 wind resistance. Once a major natural disaster occurs, it cannot be directly involved in human rescue and disaster investigation. Under this circumstance, drones can perform all-weather and complex environments to detect disaster conditions, calculate disaster data, complete disaster image transmission, and respond to emergencies and rescue missions. This is a concrete practical application case. UAVs play an active role in areas including rescue and disaster relief, circuit inspection, and law enforcement with their unique flexibility and high-altitude detection advantages.
The advantages of drones in the area of disaster prevention and emergency response 1. Line inspection. Inspection of high-voltage transmission lines, inspection of damaged parts of power towers, inspection of oil and gas pipelines.
2, forest fire prevention. Forest fire monitoring, fire accident aerial reconnaissance, mountain forest search and rescue, forest disaster relief emergency command.
3, rescue and relief. Disaster reconnaissance, high-rise fire disaster confirmation, earthquake, flood and other natural disaster reconnaissance applications.
4, * law enforcement. Anti-terrorism operations, aerial surveillance, target search, target tracking, guard surveillance, and venue security surveillance.
Compared with manned aircraft, drones have low غير مجاز مي باشدt, no risk of casualties, good maneuverability, low-visibility low-level flight, low-level flight of low clouds, good safety, wide application, and can significantly increase daily flight time and speed. The progress of work, therefore, drones have been rapidly developed in disaster prevention and emergency industries in recent years.
UAV equipped with thermal imaging technology to create emergency equipment
Through the creative development of some manufacturers, the drone's scalability from equipment performance and product form has also been strengthened. For example, with the functional combination of thermal imaging technology, drones can be equipped with visible light cameras and infrared thermal imaging cameras for aerial photography. The thermal imaging camera detects the temperature distribution of the object by detecting the infrared rays emitted by the object itself, providing more information than the visible light camera, which can be used for night vision tracking, search and rescue, equipment inspection, agriculture, forestry, animal husbandry and fishing.
For example, the forestry department uses a drone-mounted thermal imager to conduct forest fire prevention and promptly discover high-temperature flammable points. In the field of agriculture, thermal imager aerial photography can be used to detect surface and crop temperatures to understand irrigation conditions. As the temperature of industrial effluent is higher than that of river water, the environmental protection department uses a drone equipped with a thermal imager to visually detect sewage discharge during the day and night.
