Military Technology

The performance date was originally scheduled for mid-to-late August, but July and August happened to be the typhoon season. Affected by the strong typhoon, the time could only be postponed later.

Facing the bad weather, Wu Hao and the others were helpless and could only wait anxiously. For this performance, they have done countless preparations.

First, the small-scale formation combination test, and then the large formation assembly scheduling and array deformation test.

Only after all of these have reached the ideal state, will they follow the suggestions of folk culture experts invited by the Yangcheng propaganda department to design relevant programming content.

Just as actors have to rehearse behind-the-scenes before they go on stage, so does swarm formation of drones. In this way, a set of performance plans with the best performance and the highest reliability is produced.

Although Wu Hao's system can support real-time control of drone arrays for performances, it is such a big event after all. It is difficult to guarantee that there will be no accidents in live control performances in real time, so for safety reasons, pre-programmed rehearsal exercises are also required.

Of course, pre-programming does not mean rigid execution of preset programs. Wu Hao and the others can make adjustments according to the actual situation on site, and even switch to full manual control to ensure foolproof.

In order to better show the content of the performance, they did a lot of testing and rehearsal work, and it was repeated eight times just on-site rehearsal.

Of course, in order to ensure the effect of the program, they also carried out corresponding confidentiality work during the rehearsal. For example, the first few times were small-scale formation tests or placed directly in the daytime. Even in the later night tests, they turned off the lights on the drones and simplified some performances.

Despite this, their series of rehearsals have attracted the attention of the public and the media.

It's just that drone light and shadow performances are not new anymore. Everyone feels that they are no different from other performances, so they don't pay much attention to them.

On the evening of September 7th, due to the advance notice and the weekend, there were a large number of citizens and tourists on both sides of the Pearl River where the performance area was located. Preliminary estimates may have exceeded one million, and the number is still increasing rapidly.

At 8:00, as the leaders and the main guests entered the viewing platform, the performance officially started. The first is some regular performances, such as singing and dancing, which are mainly used to mobilize the atmosphere of the scene, and their performances are placed at the end.

However, on the console built by the river, Wu Hao and the others were not in the mood to watch the performances that were close at hand, but were all busy working.

"Wu Hao, I just received the data from the meteorological station. It said that the humidity on the river is relatively high today, and there are two to four breezes. I am afraid it will affect our performance." Sun Shaoyang took a report and handed it over. tell him.

Wu Hao took a look at the report, and then said to the people next to him: "It's still within our data, there's no problem, just pay close attention."

For such a big scene, the entire team is under enormous pressure. At this time, Wu Hao can only try his best to calm people's hearts and let everyone calm down as much as possible.

Otherwise, once people get nervous, it is easy to make mistakes, and it will even directly affect the success or failure of the performance. So even though he has a lot of inner pressure, he is still trying to reduce the burden for everyone.

"Half an hour left, all departments report the situation!" Wu Hao looked up at the time, then picked up the walkie-talkie and called.

"Everything is normal at each take-off site and is ready."

"Everything is normal at the landing site and it's ready."

"Every coordinate base station is normal and ready."

"Command and control is ready and everything is normal."

"The security patrol team is fine."

...

After listening to the reports of the various departments,

Wu Hao grabbed the walkie-talkie and said, "Security training team, your first task today is to cooperate with the security department to keep an eye on the outer area of ​​the performance venue to avoid human interference during the performance."

"The security patrol team understands."

"Attention from all departments, the countdown is twenty-five minutes before the performance!"

"twenty minutes."

"Fifteen minutes, each take-off field and coordinate base station pay attention, the drone and coordinate base station are turned on!"

"The coordinate base station reports that the twelve coordinate base stations around the performance venue are all powered on and operating normally!"

"Every takeoff field reported that the drones in the field have been turned on."

Wu Hao took a breath after hearing the report, and then said to the technician next to him: "Start the cluster formation and networking, and load the 'Tianyi' system!"

"The cluster formation network is successful, and the Tianyi system is uploaded. 5%, 10%, 20%... The Tianyi system is uploaded successfully, and the installation begins!"

"The Tianyi system was successfully installed, and the system was restarted. After the system restarted, it ran normally."

"The data shows that a total of 10,317 drones are in normal condition, and 183 are faulty. The failure rate is a little high, but it is still within the allowable range." Yang Fan stared at the screen and said. .

Hearing Yang Fan's words, Sun Shaoyang showed a helpless expression and said: "No way, the humidity is relatively high tonight, so the failure rate of drones is naturally relatively high."

"There is no problem with the fault now, just don't have a fault in the sky." Wu Hao shook his head and said.

This time, they have prepared a total of 10,500 drones, of which 500 are used to replace any drones that may fail at any time.

There is no way, the equipment may fail, not to mention more than 10,000 drones, even if the failure rate control is small, it is still a large number.

"The humidity is too high to just leave it like this. Start the drone and remove the drones that may malfunction in advance." Wu Hao felt the breeze by the river and frowned.

Sun Shaoyang couldn't help frowning when he heard the words: "But if you start it in advance like this, it will consume the power of the drone and affect the frequent flight."

Wu Hao waved his hand: "I don't care about that much anymore. Let's make sure that the entire fleet is normal. As for the occasional aspect, just cut off one or two moves at that time."

Hearing his words, Sun Shaoyang sighed after thinking quickly. That's right, from the current situation, Wu Hao's handling is completely correct.

Although there have been seven or eight field test rehearsals before, there has never been such a large humidity as it is now.

Although drones have been designed and manufactured with these factors in mind, there are still some problems.

"Countdown one minute!"

"Thirty seconds, twenty seconds, ten, nine, eight...two, one, the drone takes off!"

"Buzz!"

As the speed of the propellers increased, more than 10,000 drones made bursts of humming!

However, these were covered by the loud music at the scene, and the people gathered on both sides of the river finally saw that groups of fireflies were flying towards them in the sky.
