Xi an thousand Drons displane “garbled” expert: or for the procedure question

May 1, just set the “largest number of unmanned aircraft formation performance,” The Guinness World Record of the UAV Performance Team, in a named “Spring Dance, Xi ‘ an UAV performance, but because of” garbled “into embarrassment.

In charge of the activities of the XI ‘ an city wall management committee staff told the Beijing Youth Daily News reporter, the Guinness Book of World Records was created in the April 29 rehearsal, May 1 performance scene does appear to show the unsatisfactory situation, the current technical team is looking for the cause of the problem.

1374 UAV performance is “garbled” On the evening of May 1, the “Spring Dance Big XI ‘ an” performance event was held at the South Gate cultural Etiquette Plaza of Xi ‘ an city wall.

That night in the first two days to set the “largest number of unmanned aircraft formation performance,” The Guinness Book of World Records of the UAV Performance Team, in the scene photos show, the pattern left “garbled.” A member of the public who went to the scene to watch the show told the reporter, about 21:10, the UAV formation began to perform, “I was very excited when the performance began, but did not expect the left part of all ‘ garbled ‘.”

North Green newspaper reporter from the audience to provide the scene photos, the combination of unmanned aircraft “run XI ‘ an” “” 1374 “and Xi ‘ an wall and other patterns appear” garbled “, the left pattern is difficult to identify. Li Changlin’s Black Bat Squadron is responsible for the drone’s aerial performance, he told the North Youth newspaper reporter, the same day, his team’s aircraft on the north side of the drone formation, responsible for filming the back, “I saw from the monitor and the previous rehearsal is not the same, at first thought it is our angle of the problem.”

“Li Changlin said.

Experts: There is a certain probability of procedural problems After the performance, Li Changlin learned from the circle of friends “garbled” situation. “I’m not really familiar with the technical aspects of drone flight, but I guess it could be a signal disturbance,” he said. “Li Changlin told the news reporter, May 1 performance, his team’s machine also received signal interference,” the rehearsal of our filming are very clear, but May 1 I sometimes can not see the monitor, only directly to see the plane.

” A person who has had the experience of flying unmanned aerial vehicles in the industry told the North Green newspaper reporter, from the scene picture, the appearance of such “garbled” may be due to inaccurate positioning or error caused by the internal program. “Positioning is not so timely to get information, there may be a few seconds of delay or a fraction seconds of unresponsive.”

He explains that technologies such as autopilot and drones are inherently imperfect, and there is a certain probability that there are procedural problems. Li Changlin believes that technology such as drones will inevitably encounter some setbacks in the development process, “I think there is no rehearsal, even if he only once fly up, I think it is a challenge to success.”

According to his introduction, April 29 rehearsal all unmanned aircraft not only all fly up, the day performance is also very good, the camera team also made a record.

City wall CMC: Investigating the reason of “garbled” It is understood that the host of the UAV performance is the Guangdong billion Egret Media Technology Co., Ltd., by the XI ‘ an City wall management Committee is responsible for tender. Xi ‘ An City wall management committee a staff member told the North Green newspaper reporter, May 1 performance show is really not ideal, the current technical team is testing, to find the cause of the problem. The staff member says it is not yet certain that a netizen is questioning whether he or she is being disturbed by the signal.

According to the staff, the drone flight when the location is not accurate problem is more common, because the UAV once airborne, unable to carry out human control, can only follow the procedure. One of the most important items of the drone show is challenging the Guinness Book of World Records. The staff member told the North Youth newspaper that the minor challenge was “the largest number of unmanned aircraft formations”, one of which required 1374 drones to take off simultaneously. 1374 This group of figures represents the total perimeter of the 13.74 km to date the oldest and most well-preserved ancient city wall of Xian. “The record was successfully applied at the rehearsal on April 29 and the ceremony was performed on May 1,” he added. “The official told reporters that the Guinness World Record certification date and the date of the license are April 29

How to determine the location of illegal washing? Huang told reporters: “Altitude overlooking the picture shows a large number of sand accumulation, and found that there are production lines, to confirm whether to wash sand point, we have to carry out on-site confirmation.”

Advertising It is understood that these sea sands are heavily used in construction.

And when the sea sand does not meet the requirements of the building, not only there are hidden dangers, while washing sewage discharge will destroy the ecological environment, resulting in land salinization. “With the unmanned aerial vehicle, we can quickly find illegal sand washing point, on-site forensics timely and environmental protection, water and other departments to communicate to solve.”

Back to the Yongxing office, Huang in the eco-linkage monitoring Center to reporters on the day of the drone shot of the image content.

No matter where the location, how many machines and workers in the operation, as long as the UAV captured images, in the monitoring center of the live video, can be at a glance.

Using UAV to collect environmental pollution clues is an important measure of the ecological linkage monitoring platform of this hospital, and it also finds clues such as seawater pollution and illegal water harvesting.
