Today (February 24), Qianjiang Evening News hour news reporters follow the Hangzhou traffic police highway brigade UAV squadron scene duty, revealed the whole process of UAV squadron law enforcement (previously reported here).
For a time, Hangzhou traffic police drone police in the circle of friends refresh.
How many people are there in the team? How are the team members 0ed? Who is the Lord Flyer? What kind of assessment does it need to go through?
Before we answer those questions, let's look at a set of data --
Starting January 2020, Hangzhou Traffic Police UAV Squadron began to put into traffic management combat work, a total of 4,950 flight hours throughout the year, off-site law enforcement data more than 12,800; More than 2,900 times of field punishment; On the expressway (viaduct and ring city) accidents, anchoring, construction and congestion and other air warning more than 3,000 times; UAVs evacuated incidents and cleared parked vehicles more than 2,400 times through loudspeakers.
2) 8 hours a day, closed training for a month
The most difficult tests are hovering in the air and circling
What tests do you need to pass to become a drone traffic police pilot?
Sun said that unlike the drones used by many amateur photographers, police drones are bigger, have more complex functions and are more difficult to operate. "Generally, close training is required for nearly one month, and one can only obtain the qualification after taking theoretical and practical tests."
At the end of 2019, Sun and other colleagues attended the Hangzhou traffic police's first drone pilot training. "The training was closed for nearly a month, four hours in the morning and four hours in the afternoon, all learning the theory and practice of UAV operation."
"The police drone test is more difficult than the car test." Sun Jie recalled that when taking the exam, the examiner would first turn off the navigation system of the drone and updat it with a remote control without a display screen. The flying hand would only observe it with the naked eye, and operate the UAV hovering and circled around a figure of eight by hand, which was 2 meters high and 10 meters away from it.
"A purely manual drone, unlike what you see now, can hover in the air even if we let go of the hand, it will float in the wind, and it is like a moving car, it pushes forward a little bit, and there is inertia, so during the test, the pilot needs to hold the drone firmly."
Sun Jie told reporters that one of the most difficult exam subjects was operating a drone "around eight characters." "Examiners will put a good triangle hat, cone hat, placed a simulation of a figure of eight, the test UAV head to follow the figure of eight turn, not like the general translation forward, very difficult."
Sun Jie has been participating in UAV operation training since the end of 2019, and has been flying for more than a year now. He is already a "veteran" in the UAV squadron.
Using drones to participate in traffic management on urban elevated roads is a new attempt, which also requires pilots to pay attention to the surrounding environment. "Before take-off and during flight, be sure to observe the nearest obstacles, such as signal towers and light posts in the city. If the drone hits them during flight, that's a big deal. In addition, you need to pay attention to nearby signal sources and interference sources during flight." Sun Jie said, for example, under some elevated Bridges, the signal shielding is very serious, the UAV in flight should try to avoid passing. "There are also some junctions on the viaduct surface, and there is geomagnetic interference in places where an iron bar runs through the middle. When the UAV approaches, it will be confused between southeast, northwest and northwest, and it should also avoid approaching when taking off and landing."
