The performance date was originally scheduled for mid-to-late August, but July and August happened to be the typhoon season. Due to the impact of strong typhoons, the date had to be postponed.
Faced with the bad weather, Wu Hao and the others had no choice but to wait anxiously. They have done countless preparations for this performance.
First, there is the small-scale formation combination test, and then there is the assembly and dispatch of the large formation and the array deformation test.
Only after these have reached the ideal state, they will follow the suggestions of folk culture experts invited by the Yangcheng Publicity Department to design relevant program content.
Just like actors must rehearse repeatedly behind the scenes before performing on stage, drone swarm formations also require corresponding rehearsals. In this way, we can come up with a performance plan with the best performance and the highest reliability.
Although Wu Hao's system can support real-time control of drone arrays on site for performances, it is such a big event after all. It is difficult to control the performance in real time on site to ensure that there will be no accidents, so for safety reasons, pre-programmed rehearsals must be carried out.
Of course, pre-programming does not mean rigidly executing the preset program. Wu Hao and the others can make adjustments according to the actual situation on site, and can even switch to full manual control to ensure nothing goes wrong.
In order to better present the performance content, they did a lot of testing and rehearsal work, and the on-site rehearsal was repeated eight times.
Of course, in order to ensure the effectiveness of the program, they also carried out corresponding confidentiality work during the rehearsal. For example, the first few tests were conducted in small-scale formations or during the day. Even in subsequent night tests, they turned off the lights on the drones and simplified some performance content.
Despite this, their series of rehearsals still attracted the attention of the public and the media.
It's just that drone light and shadow shows are no longer new. Everyone thinks 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 it continued to increase rapidly.
At eight o'clock, as the leaders and major guests entered the auditorium, the performance officially began. First, there are some regular performances, such as singing and dancing, which are mainly used to arouse the atmosphere of the scene. As for their performances, they are put at the end.
However, on the console set up by the river, Wu Hao and the others were not in the mood to watch the performances close at hand. Instead, they were all working nervously.
"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 is a breeze of two to four levels, which may have an impact on our performance." Sun Shaoyang handed over a report. Tell him.
Wu Hao took the report and looked at it, then said to the people next to him: "It's still within the allowable range of our data. There's no problem. Just pay close attention."
For such a big scene, the whole team is under great pressure. At this time, Wu Hao could only try to calm people's hearts as much as possible and let everyone calm down as much as possible.
Otherwise, once people become nervous, it is easy to make mistakes, which may even directly affect the success or failure of the performance. So even though he was under a lot of pressure, he still worked hard to reduce the burden on everyone.
"There's still half an hour left. All departments will report the situation!" Wu Hao looked up at the time and then picked up the walkie-talkie and called.
"Everything at each departure airport is normal and ready."
"Everything is fine and ready at the landing site."
"Everything at each coordinate base station is normal and ready."
"Command and control is ready and everything is normal."
"All is well with the security patrol team."
…
After listening to the reports from various departments, Wu Hao grabbed the intercom and said: "Security training team, your first task today is to cooperate with the security department to keep an eye on the peripheral areas of the performance venue to avoid human interference during the performance."
"The security patrol team understands."
"Attention all departments, there is a twenty-five minute countdown before the performance!"
"twenty minutes."
"Fifteen minutes, all takeoff airports and coordinate base stations, please pay attention. The drones and coordinate base stations are powered on!"
"The coordinate base station reports that all twelve coordinate base stations outside the performance venue are powered on and operating normally!"
"Each airport reported that the drones on site 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 network and load the 'Tianyi' system!"
"The cluster formation network has been successfully established, and the Tianyi system has been uploaded. 5%, 10%, 20%... The Tianyi system has been successfully uploaded and the installation has begun!"
"The Tianyi system was installed successfully 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 have malfunctions. 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: "There is no way, the humidity is relatively high tonight, and the drone's failure rate will naturally be relatively high."
"It's okay to have a malfunction now. Just don't worry about it happening in the sky when the time comes." Wu Hao shook his head and said.
This time they prepared a total of 10,500 drones, 500 of which are used to replace drones that may malfunction at any time.
There is no way, the equipment may fail, not to mention there are more than 10,000 drones. Even if the failure rate is controlled to be small, it is still a large number.
"The humidity is too high. You can't just leave it like this. Start the drones and eliminate drones that may malfunction in advance." Wu Hao felt the breeze by the river and frowned.
Sun Shaoyang couldn't help but frown when he heard this and said: "But if you start it in advance like this, it will consume the power of the drone and affect the flight time."
Wu Hao waved his hand: "I can't control that much. Let's make sure the entire fleet is normal first. As for the regularity, just cut off one or two actions at that time."
After hearing his words, Sun Shaoyang thought quickly and sighed. Yes, judging from the current situation, Wu Hao's handling of this situation is completely correct.
Although the field test had been rehearsed seven or eight times before, none of them had such high humidity as now.
Although these factors have been taken into consideration 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 propeller speed accelerated, more than 10,000 drones made a buzzing sound!
However, these were all covered by the loud music, and the people gathered on both sides of the river finally saw groups of fireflies flying towards them in the sky.
