But after thinking about it, the remote control should be in good condition, and if you don't want it, you can also resell it, and you can make up for your losses to some extent.

So, Li Shan turned around again, dragged his tired legs to find the remote control, and found it easily. After Li Shan took it in his hand, he only took a cursory look at it, and then stuffed it into his bag.

As soon as he got home, it was only eight o'clock in the evening, but Li Shan lay down directly on the bed. Today, not only did he feel very tired physically, but he also felt more tired psychologically, he could still hold on, but as soon as he got home, he felt that he couldn't move a finger.

He slept until seven o'clock the next morning, and waking up at this time every morning was a habit he had already developed, because the Hongqi factory went to work at eight o'clock in the morning.

But the unit he is in now is mainly to serve in the field, so he usually stays in the factory and has nothing to do. Because the environment in which the field service is located is generally more difficult, and it is two or three months to go out, it is nothing for a bachelor like Li Shan, but for those workers who are old and young, it is more painful, so when they are not on a business trip, the unit will be more relaxed in the management of their people, so that they can try to deal with their family affairs when they are not on a business trip, and eliminate their worries to the greatest extent.

Li Shan was lying on the bed and hesitated whether to say hello to the unit, he felt as if he hadn't eased up at this time, so he called Director Liu and said that he had something to do and needed to take another day off. Director Liu didn't say much, only said, "Okay." He hung up the phone.

So, Li Shan closed his eyes and fell asleep again, until he was woken up by his mother for lunch at noon, and then he got up.

Regarding the movements in the past few days, Li Shan only said that he has recently fallen in love with the sport of drones, and has participated in the activities held by the UAV Association in the past few days, and the unit has nothing to do recently, so he took a few days off.

Seeing that Li Shan has been fiddling with drones lately, my mother wondered when this kid became obsessed with these things, I'm afraid it will cost a lot of money. Regarding his mother's question, Li Shan only said that these things are some toys, just like the ones for children to play in front of some stores, which are actually not worth a few dollars.

Mom sometimes has seen the community, some adults lead children to play with drones, she has a lot of complaints about Li Shan's addiction to this, thinking that Li Shan is not doing business, but my father is very open, although he does not understand this industry very well, but from TV and other media also learned some, he understands that the drone is similar to the kind of rice country in the Middle East to chase and kill radicals, I think the drone industry is very noble, how can it be regarded as a high-tech field, it is also a good thing for my son to study in this area, this is at least much stronger than him playing games in Internet cafes all day long, so he does not object to Li Shan's hobby。

Li Shan was secretly amused in his heart, if they knew how much money they had invested in this industry, they might just scold themselves for being a loser.

Li Shan slept for twelve hours this time, and now he has completely recovered, and when he was okay in the afternoon, he began to count yesterday's results.

The first thing he checked was his drone, the fuselage of the drone was completely pierced by the bullet, and the integrated circuit board on it cracked due to the impact of the bullet, fortunately it was not completely broken, otherwise it would have fallen on the spot, however, this board can no longer be used, in addition, the IOC used to control the reversal is damaged, and there are also rudder trimmers, accelerometers, and some small parts are also damaged to a certain extent, if you want to repair this drone, you have to replace the integrated board, The fuselage, as well as the damaged parts, there is really no need to repair it, it is better to reassemble a drone, remove the useful parts on it, and install it on the newly assembled drone, which is more cost-effective.

As a result, this No. 2 drone, which has repeatedly performed miraculous feats for Li Shan, is completely abandoned.

He picked up the captured third-generation aircraft again, and saw that the damage above was more serious than his own, and his crossbow arrow was full of power, causing a lot of damage to this drone, and most of the parts on it were damaged, and there were few things that could be used, Li Shan took a special look at the bullet launch device, and there was still one bullet left on it that could still be used, and the other parts were seriously deformed and could not be used at all, seeing these trophies, Li Shan was disappointed, his No. 2 machine had been scrapped, and he was originally counting on being able to recover some losses on this machine, but now it seems that this can only be his wishful thinking。

His No. 2 machine is a second-generation and a half-generation machine, and if he wants to reassemble a similar machine, the investment in it can be described as a huge expense, but where does he still have these funds.

He now has three, namely the No. 1 machine, the No. 3 machine and the No. 4 machine, of which the No. 1 machine is barely a second-generation aircraft, which can only be used as a training aircraft, and the No. 4 machine is his killer weapon and he does not dare to use it easily, so only the No. 3 machine can be used for daily activities, but due to the relatively high damage rate of the drone, once the No. 3 machine has any damage, then he will usually face a situation where there is no organic use.

This battle is really not worth fighting, and if it doesn't work, let that guy compensate himself, and there's nothing to be ashamed of. Isn't it always like this in previous wars, the winning side can ask the defeated side to cede land for compensation, and it shouldn't be too much to make this request yourself, but this kind of thinking Li Shan is just thinking about it.

At this time, he saw the seized remote control again, this remote control was more than twice as large as his previous remote control, and the weight was quite heavy, and it looked the same.

Li Shan took this remote control in his hand and checked it, thinking to himself that this Wan Guoliang is really an idiot, what is he doing with the remote control so heavy, how inconvenient it is to carry, but then he thought about it, no, who would make this remote control so clumsy, is there something unknown in it?

Thinking of this, Li Shan suddenly became interested, turned on the power switch above, and wanted to study what was in it.

A row of menus appeared on the screen of the remote control, which read: drone body, flight control system, data link system, launch recovery system, power supply system, etc., in addition to these main menus, there are some sub-menus under it, which looks extremely complicated.

What's the use of all this?

All afternoon, Li Shan studied this remote control, and through searching on the Internet, he finally figured out that this remote control is far from being as simple as he imagined, and it is more suitable to say that it is a small ground control station than a remote control.

This kind of control station is generally used in large unmanned aerial vehicle systems, it can be built on the ground, can also be located on the vehicle, ship or other platforms, through the control station, not only can obtain the information detected by the UAV, but also can issue instructions to the UAV, control its flight, so that the UAV can successfully complete the task.

The control station is usually ground, or ship-based, or it may be airborne on the mother aircraft, and the control station is the flight control center to achieve human-computer interaction, and is generally the UAV mission pre-planning center.

Through the control station, the controller uses the uplink communication link to send instructions to the UAV, control the flight of the UAV, and control the various mission loads carried by the UAV. Equally. Through the downlink communication link, the drone sends back information and images to the operator. The information includes payload data, status information (monitoring data) of each subsystem on board, position information, etc., and the launch and recovery of the UAV can be completed through the main control station or the satellite-based control station (auxiliary).

The control station is often integrated with a communication system to contact the outside world, mainly to complete the acquisition of weather information, network information transmission between various systems, receive tasks assigned by superiors, and report information to superiors or other departments.

In addition, the remote controller is equipped with an automatic flight control system for drones.

The basic task of the automatic flight control system is to maintain the stability of the UAV's attitude and track when the UAV is interfered with in the air, and to change the UAV's attitude and trajectory according to the requirements of the ground wireless transmission command, and to complete navigation calculation, telemetry data transmission, mission control and management, etc. The basic task of the UAV navigation system is to control the UAV to fly according to the predetermined mission route. The basic condition for the realization of navigation is that it must be able to determine the real-time position and speed of the UAV's flight and other relevant parameter information. The basic task of the guidance system is to determine the relative position of the UAV to the target, control the UAV to fly, and with a certain degree of accuracy, guide the UAV to fly to the target along a predetermined trajectory. For UAVs, on the basis of the automatic flight control system, the navigation, guidance and flight control systems are interconnected.

This remote control also has a powerful function, that is, its communication function, Li Shan deduced from its strong power that the control distance of this remote control is at least more than 100 kilometers, although he has not tested it, he believes that there should be no problem. In the past, he transmitted data and implemented control through a similar way of mobile phone signals, but there is also a problem, that is, where the mobile phone signal cannot reach, it is difficult to achieve effective control, and now only this remote control can implement long-distance control of the drone, just imagine, within a radius of 100 kilometers, it is enough to complete any flight mission in most cities.

The remote control in front of him is a reduced version of the control station, and the drone captured by Li Shan does not have relevant parts to match it, therefore, most of the functions on this remote control have not played their due role, Li Shan does not know why Wan Guoliang did not configure the corresponding parts, so he used it, but in the end he cheapened himself. Li Shan can't care so much, he is now thinking that if the corresponding components are installed in the drone and cooperate with this remote control, it will also have the function of a fourth-generation aircraft.
