After the electronic enthusiasts 8:00 am According to foreign media reports, civilian UAV has always been very vulnerable to external threats of a "jobs" and in the future needs to become more and more drone delivery times, Amazon has Beginning to apply for a patent for the "unmanned aircraft fleet" that can safely land and prevent "hijacking".
It is reported that one of Amazon's latest patents is called “Autonomous Flight Unmanned Opportunity Coping Strategyâ€. The main purpose of this patented technology is to help drones and loaded goods from hackers. The patent shows that the Amazon drone fleet has a communication network for information transmission, through which the drone can send and receive data on location, heading, altitude and other data.
For example, the first drone can receive information from the second drone. If the data collected by the two shows inconsistency, the airborne system will determine that the first drone has been hacked or damaged. . Immediately, the unmanned person is directed to a safe area for landing, parking, or continuing the next itinerary under the guidance of other drones nearby.
Moreover, in the future, Amazon UAVs can also judge whether the drone is hacked by accepting the direction of the signal. For example, if the drone receives a navigation signal from below at a certain height, but actually receives a navigation signal from above, the built-in system of the drone will judge that the system is invaded.
Of course, even when the drone is hacked, Amazon still wants to protect the drone by airbag cushioning or parachuting. In the patent application, we even saw the words about "AutorotaTIon" and other technologies.
In addition to hacking, more straightforward "hijacking" methods such as direct shooting are also aspects that Amazon needs to consider. As shown in the figure, when the possible attack weapon is close to the fuselage, the onboard “compromise module†module will detect the presence of the arrow and then initiate the fail-safe mechanism to allow the autonomous drone to take an emergency flight. The posture is protected from attack and landed on the ground safety area for inspection. Of course, the arrows in the patent illustration are just one of the threats that Amazon drones may encounter in the future, and weapons such as bullets can fly faster than they can, so Amazon drones may still be affected in the future. Some serious threats to small firearms weapons.
It should be pointed out that the Amazon drone delivery service has recently completed the first drone express delivery in the UK, which is far more efficient than traditional ground distribution services. Amazon said that the user who enjoyed the drone express delivery was a man living near Cambridge who bought an Amazon Fire TV and a pack of popcorn online last week.
At the time of delivery, Amazon's drone took off from a small logistics center near Cambridge and took a 4.7-pound package of about 4.7 pounds to the customer's home in just 13 minutes.
Outside analysis believes that the successful completion of this drone express indicates that this new delivery mode is officially launched in Amazon. In the future, the company will deliver drones during the day and seven days a week, with each weather permit. The package weight must not exceed 5 pounds (about 2.3 kilograms), and 83% of the products sold by Amazon do not exceed this limit. (General / Tom)
