Does Huifei have anything else besides plant protection drones?

UAV certification training, I recommend you to take the certificate of the China Aviation Sports Association (ASFC), which is more qualified.

It's not very good, and XAG's after-sales service is very poor, don't use XAG's.

At present, the best plant protection drone is DJI's MG1S plant protection drone, whether in terms of brand awareness or after-sales service of products, DJI is the best, and the price is 42,000 yuan.

Based on the MG-1, DJI's flight control system, environmental awareness system, and spraying system have been upgraded.

In terms of flight control system, the MG-1S adopts the DJI A3 flight controller, and its algorithm has been fully optimized to help the drone fly smoothly even when the liquid medicine is shaking. With the addition of dual barometers and dual compasses, the flight control system can immediately switch to another set of sensors when the flight data is abnormal to ensure flight safety.

In terms of environmental perception system, a high-precision millimeter-wave radar is installed at the front, rear and bottom of the MG-1S. The front and rear oblique radars can detect the terrain in advance and combine them with the downward radar to accurately set the altitude. Through uninterrupted scanning, the MG-1S can perceive the terrain changes in the flight direction in advance, and adjust the flight altitude in time according to the terrain and crop altitude, so as to achieve terrain-following flight and uniform spraying.

In terms of spraying system, MG-1S is equipped with two customized water pumps, which can control the front and rear pairs of spray heads respectively, and allow users to choose three different spraying modes according to different operation needs: front single spray, rear single spray and full spray. The new pressure sensor and flow sensor can monitor the spraying flow rate in real time, and dynamically control the flow rate and speed of the agent during the operation. The newly designed two-stage spraying system solves the phenomenon of uneven spraying and substandard settlement that occasionally occurs when the traditional sprinkler heads operate in the variable operation at both ends of the route; The new type of sunken nozzle makes use of the downward pressure air field, and the nozzle assembly realizes instant opening and stopping, so as to spray more accurately and improve the effect of liquid chemical sedimentation; The water pump and medicine box have also been optimized for easy dosing, disassembly and cleaning; The screen area is 20 times larger than the previous generation, and the dual-screen design reduces nozzle clogging caused by water, powder, or chemical solutions.

Don't listen to the blind blowing downstairs, DJI's after-sales service is really poor, out of the T16, I don't care about the previous MG series users, and DJI has a lot of battery problems, it will break if it is rushed twice, it is not recommended to buy.

Take the best aircraft from XAG and DJI, for example. XAG P30 2019 and DJI T16 plant protection drones have some things in common, such as the volume of the medicine box is 16L, which can support the three-dimensional operation of the AI intelligent engine, the plug-in design of the medicine box (XAG first recommended this design, and the follow-up DJI copied it), the aircraft has a dot function, and the control mode has AB point mode Manual control RTK flight, and at the same time has the waterproof function of the whole machine.

In order to better answer this question, the key parameters are compared as follows:

Parameter comparison. XAG P30 2019

DJI T16 XAG and DJI currently launch new phones every year, but there is one difference between the two. XAG's previous aircraft are still available for use and can be installed with upgrade packages to continue service. Even now, there are users using XAG's 2017 plant protection drone to provide plant protection services for farmers.

However, it is rare to see DJI's predecessor products, because DJI will eliminate past users when it comes out with a new machine, which makes users very chilled, maybe DJI is just a company that sells products, and does not want to provide users with meaningful services.

It's good, there are two giants of plant protection aircraft, DJI and XAG, and there is not much difference between the two aircraft. The advantages are high precision, high operation efficiency and good effect. The disadvantage is that the price is too expensive, the follow-up maintenance is expensive and not very convenient, and the battery replacement is also expensive.

It is recommended that you use it. I am from Shanxi, and my family uses XAG's plant protection drone, because the farmland area is relatively large, if you use manual or tractor spraying, it will be very time-consuming and trample on some crops. So drone spraying is very good, if you don't want to buy it, you can also find a pilot to help you spray.

XAG 20 is not broken if you don't use it, it will be broken when you use it, some accessories can't go to insurance, and if you break it, you have to return to the factory It takes more than ten days to come back Do a fart job It's too pit.

There should be money to be made, and now the elderly farmers can't take medicine, and the young ones all go to work, so that there is a good way to make money.

I don't know, this drone should not have a name, I think the quality of 4 meters should not be too good, I suggest you think about it, don't blindly buy, so think.
