With a much more friendly cost than helicopters, unmanned aerial vehicles quickly assumed the responsibility of preventing and controlling the epidemic all over the country. The most common use method is to use unmanned aerial vehicles to shout to citizens and villagers to remind everyone to wear masks. The advanced version of unmanned aerial vehicles can even deliver masks for emergency use while shouting, which is very intimate.
Besides masks, unmanned aerial vehicles can remotely measure the body temperature of residents, avoid infection caused by contact, carry out mobile propaganda and spread epidemic prevention knowledge. According to the actual measurement, a small unmanned aerial vehicle with a battery life of about 45 minutes can quickly measure the body temperature of a person with more than ten floors of high-rise buildings through visible light and infrared detectors. The measurement error is only about 1%, the measuring speed is far higher than that of people going upstairs and visiting the door layer by layer, and it can also effectively reduce contact. The same technology can also be applied to crowded areas such as expressways, railway stations, shopping malls, etc.
In addition, the use of unmanned aerial vehicles to disinfect specific areas is also more and more popular. Compared with the traditional disinfection method carried out by hand or truck, unmanned aerial vehicle can quickly orient the place to be sprayed and cover a larger area, therefore, it is helpful to improve public health and reduce the risk of spreading the virus through surface contact.
In the field of express delivery, unmanned aerial vehicles have more important applications. Before that, various logistics companies have tested the delivery of unmanned aerial vehicles and unmanned vehicles. This fight against coronavirus can just become the real stage for them to try their skills, it will even get explosive advancement. Between cities, large and medium-sized fixed-wing UAV can be used for express delivery, while inside cities, small and medium-sized multi-axis vertical takeoff and landing unmanned aerial vehicles are used for door-to-door delivery to avoid direct contact between people. At present, both of these two types of unmanned aerial vehicles have relatively mature products, and all that needs to be done is to put them into operation immediately and continuously improve their performance. For example, SF’s large cargo unmanned aerial vehicle has a maximum load of 1.5 tons, while the planned giant unmanned aerial vehicle can transport 5 tons of goods at a time. I believe that soon, we can use the trunk large cargo unmanned aerial vehicle, the three-level unmanned aerial vehicle transportation system and the three-level unmanned storage system of regional cargo unmanned aerial vehicles and terminal cargo unmanned aerial vehicles build a new logistics that arrives overnight.
