UAV application in emergency rescue field


Recommended Posts

Every year, China's human casualties and economic losses caused by sudden public events such as natural disasters, accidents, and social security events are huge. The emergency industry, as an important material and technical guarantee for emergency management, is increasingly receiving national attention. The effective application in rescue can make every minute count, which not only improves rescue efficiency but also reduces the danger of personnel.


In emergency rescue events such as industrial accidents, natural disasters, fire accidents, public events, and public transportation, drones do not need a runway, are small in size, take off conveniently, are flexible in operation and can respond in a timely manner. They arrive at the accident site from empty roads and mount HD The camera system will transmit the scene situation to the command center as soon as possible, and provide strong data support for the next step of the command center deployment. In addition, UAVs can also carry important functions such as emergency search and rescue, airdrop supplies and air communication relay in disasters by mounting loads such as infrared thermal imaging, lidar and emergency communications.


MMC, as a leader in industrial drones at home and abroad, has provided complete solutions for drone applications in many fields. At present, the applications in the field of emergency rescue of drones have the following capabilities:


First, unified and coordinated rapid scheduling and deployment


Through the automatic dispatch platform of the UAV emergency command and dispatch center, it can quickly dispatch the drone for investigation in the event of an emergency; when the target area cannot be covered by the drone, the system can dispatch unmanned persons. The command vehicle of the aircraft entered the vicinity of the target area in an optimal route, releasing the drone for operation. After the drone's initial investigation of the target area is completed, the dispatching system can provide uninterrupted cruising flight capabilities in the area according to the needs of the commander, providing uninterrupted disaster data for the commander's real-time decision-making. When the communication link in the area is interrupted, the system can quickly deploy multiple batches of drones equipped with temporary communication equipment to quickly recover the communication link in the area. Through the command and dispatch capability of the system platform, the single drone has a short range and lacks empty time to provide long-term flight operation services. At the same time, due to the system's unified dispatch command, unified route planning, and automatic takeoff and landing remote remote control Completed, greatly reducing the ability of front-line personnel to professionally control the drone, saving a lot of labor costs.


Second, multi-dimensional real-time monitoring


Relying on the rapid deployment capabilities of UAVs and the perspective of high-altitude detection, it monitors and evaluates the target area by carrying a variety of surveillance camera equipment. Conventional optical camera gimbals provide stable and zoomable high-resolution visible light data images, infrared light gimbals provide thermal imaging data images, ground-based lidars provide three-dimensional model data of ground high-resolution maps, and gas detectors provide real-time monitoring of various harmful gases in the area Data, multispectral cameras can provide monitoring data for crops, pests and diseases such as crude oil spills. The data returned by the corresponding monitoring equipment is carried by the drone. After the data is collected by the monitoring system cloud platform, the high-resolution real-world image in the monitoring area is drawn in real time through big data calculation and superimposed on the 3D terrain data, which is accurately and accurately restored. Monitor environmental data. The monitoring cloud platform can also perform on-site event situation analysis based on the currently restored data, combined with meteorological and hydrological data, and provide treatment suggestions for commander decision analysis.


Third, emergency materials are put into transportation

UAVs can provide rapid delivery of materials and equipment to the mission area, and can quickly resolve emergency needs for materials in the area. In areas where personnel cannot enter and drones cannot land, materials and equipment can be dropped by means of fixed-point parachuting or rapid low-altitude throwing. In particular, in the case of emergency treatment for injured people, drones can quickly solve various tasks such as drug delivery and defibrillation equipment placement, ensuring that other personnel in the area can quickly rescue the personnel facilities before the arrival of other rescue teams.


Fourth, direct rescue

Drones can enter areas where people can't reach to perform operations, and directly assist in emergency situations in real time. When there is a fire in the city, especially in the case of high-rise buildings, traditional rescue methods face the problem that the fire extinguishing equipment cannot be covered. At this point, the rescue team can release the fire-fighting drone carried by the vehicle to the air, and fire fire extinguishing bombs at high-rise fire sites to directly extinguish the fire. Many modern high-rise office buildings use toughened glass exterior walls. At this time, if an internal fire occurs, personnel cannot escape by opening the glass. At this time, a window-drone drone can be dispatched to break the glass of the fire floor at a fixed point to provide a passage for internal personnel . After the earthquake, drones can carry life detection equipment to carry out life detection, quickly locate and rescue at fixed points in areas where people cannot reach quickly.


V. Multi-sector collaborative data sharing

Various monitoring data obtained in the future UAV background cloud system can be shared with other coordinating departments. The data that is shared immediately can be sent to the rescuers at the scene as soon as possible, and can also be synchronized to the fire, weather, water, Earthquake and other synergy departments.


With the advent of 5G communication technology, it provides higher bandwidth, lower delay and wider signal coverage. Bringing more reliable high-speed data links to future drones, relying on 5G data links, in the emergency rescue, the aircraft will appear in a distributed configuration of the aircraft and centralized management of command and dispatch. Aircraft fixed stations, UAV mobile command vehicles, and individual mobile UAVs are deployed in various areas of the city to cover the entire city with UAV flight areas.


A complete drone coverage network must be supported by a strong and stable command and dispatch system and a data cloud processing system. Through highly intelligent and efficient automatic dispatch control, people, cars, and stations carrying drones in various areas can be implemented in Quick deployment of drones in emergencies, real-time monitoring and timely rescue. In the near future, UAV systems, as the vanguard of emergency rescue systems, can replace traditional personnel at the forefront of rescue teams and provide a full range of rescue services.


Although drones are playing an increasingly important role in emergency rescue, the current development of the industry is still far from mature, the product quality is uneven, and the drone industry does not yet have a corresponding standard for product development. Definition, lack of normative constraints. Therefore, it is imperative to formulate various standards for the drone industry as soon as possible, so as to achieve an orderly overall development, and to leap from quantity to quality and move towards a sustainable road.
