The performance date was originally scheduled for mid-to-late August, but July and August coincided with the typhoon season, and due to the impact of strong typhoons, the time had to be postponed.

In the face of bad weather, Wu Hao and the others were helpless, so they could only wait anxiously. For this performance, they have done a lot of preparations.

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

Only after these are in an ideal state, they will follow up on the suggestions of folk culture experts invited by the Yangcheng propaganda department to design relevant program content.

Just as actors need to rehearse behind the scenes before they go on stage, drone swarm formations also need to be rehearsed accordingly. So as to come up with a set of performance plans with the best performance effect and the highest reliability.

Although Wu Hao's system can support real-time control of drone arrays for performances, it is such a big event after all. It's hard to guarantee that there won't be accidents when you control the show in real time, so pre-programmed rehearsals are necessary to be on the safe side.

Of course, pre-programming doesn't mean rigid execution of pre-programmes. Wu Hao: They can adjust according to the actual situation on the site, and can even switch to full manual control to ensure that nothing goes wrong.

In order to be able to better present the content of the performance, they did a lot of testing and rehearsal work, and the rehearsal was repeated eight times in person alone.

Of course, in order to ensure the effectiveness of the show, they also carried out corresponding confidentiality work during the rehearsal. For example, the first few times were small-scale formation tests or directly placed in the daytime, and even the later night tests, they also turned off the lights on the drone and simplified some of the performance content.

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

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

On the evening of September 7th, due to the advance notice and the weekend, a large number of citizens and tourists on both sides of the Pearl River where the performance area is located may exceed one million, and it continues to increase rapidly.

At eight o'clock, as the leaders and main guests entered the viewing platform, the performance officially began. First of all, there are some regular performances, singing and dancing, which are mainly used to arouse the atmosphere of the scene, and their performances are placed at the end.

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

"Wu Hao, I just received data from the meteorological station. It is said that the humidity on the river today is relatively large, and there are two to four levels of breeze, which I am afraid will have an impact on our performance. Sun Shaoyang took a report and handed it to him.

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

For such a big scene, the whole team is under tremendous pressure. At this time, Wu Hao could 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 this performance. So although he is under a lot of pressure in his heart, he is still trying to reduce the burden for everyone.

"There is still half an hour, and the departments will report the situation!" Wu Hao looked up at the time, then picked up the walkie-talkie and called.

"Everything is normal and ready at all take-off sites."

"Everything is normal and ready at the landing site."

"Everything is normal and ready for each coordinate base station."

"The command and control department is ready, everything is normal."

"The security patrol team is all in order."

……

After listening to the reports of various departments, Wu Hao grabbed the walkie-talkie and said: "Safety 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 departments, the countdown is twenty-five minutes before the performance!"

"Twenty minutes."

"Fifteen minutes, pay attention to the take-off fields and coordinate base stations, and the drones and coordinate base stations will be turned on!"

"The coordinate base station reported that the twelve coordinate base stations on the periphery of the performance venue were all turned on and running normally!"

"Each take-off site reported that the drone in the field has 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 networking, load the 'Tianyi' system!" ”

"The cluster formation network was successful, and the Tianyi system was uploaded. 5%，10%，20%…… The system has been uploaded successfully, and the installation begins! ”

"The Tianyi system was successfully installed, the system was restarted, and the system operated normally after the system was restarted."

"The data shows that a total of 10,317 drones are in normal condition, and one hundred and eighty-three are malfunctioning. The failure rate is slightly larger, 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, and the failure rate of the drone is naturally relatively high." ”

"It's okay to break down now, just don't go to heaven when the time comes." Wu Hao shook his head and said.

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

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

"The humidity is too high, you can't just leave it there, start the drone, and remove the drone that may malfunction in advance." Wu Hao felt the breeze by the river, frowned, and said.

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

Wu Hao waved his hand: "I can't care so much, let's make sure that the entire fleet is normal first." As for the occasional aspect, just cut one or two actions when the time comes. ”

Hearing his words, Sun Shaoyang thought about it quickly, and then sighed. That's right, judging from the current situation, Wu Hao's handling is completely correct.

Although there were seven or eight rehearsals for field tests, none of them had such a high humidity as now.

Although these factors have been taken into account when designing and manufacturing drones, there are still some problems.

"One minute countdown!"

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

"Buzz!"

As the speed of the propeller increased, more than 10,000 drones let out bursts of humming sounds!

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