The application of drone in ecological protection

Due to the unique bird's-eye view, the drone can observe a wider range. The drone can offer you help no matter you are an agency selling real estate or you are a forest patrol.
In fact, drones, a cutting-edge technology, have been applied in ecological preservation areas, which would make the protection works easier. Let us see how it works.

In forest degeneration areas, the traditional plating method needs a large quantity of manual labors, which is time-wasting. In 2015, a new British company designed a drone, which can sow a special seed capsule into the soil. In practice, just like a bullet, the seed capsule would be shot and fixed into the soil. At the same time, the seed will rupture and can be exposed in the sunshine, then it will grow.

That drone can successfully sow ten seeds per minute, and it is estimated that a group of drone can sow 36,000 seeds for maximum every day.

However, the drone can be used before seeding. Scientists can take advantage of drones to make aerial photography towards the forest degeneration areas for the ground mapping. Moreover, the drone is able to supervise the illegal plant-cutting in the forest degeneration areas.

Supervise the habitats

The drones, with light weight and good performance, can shoot the detailed aerial photography, even converted into 3D model. Scientists can quickly identify the change of habitats when they use the drone to shoot systematically such as the periodic shooting for a certain area. The change of habitats can attribute to the the change of density of crown, erosion of river bed, quality and quantity of water, etc.

Drones can make aerial shooting for a large area in very short time. The scientists can analyze the change of the human activity, such as plantation destroy and expansion of the market around the particular habitats through image scaling.

fight against poacher

Drones can use with various tools, and one of them is thermal imaging camera. In some situations, this camera can transfer the video real-time to the researchers. Those two factors make the drones become the effective weapon to attack the poaching. Thermal imaging camera can shoot the human's appearance and shape through the trees and can track the campfire set by the poachers. Tracking poachers by drones is comparatively safe since the poachers often hold the weapons. Knowing the position of poachers contributes to the arrest, and stops the poachers from hiding.

tracking animals

The biologists in ecological preservation areas are using radio to track the displacement distance of animals and their habitat scales and judge whether the animals have entered the prohibited areas (non-preservation areas or human activity areas).

But the radio is regarded as an out-of-date method and time-consuming, because scientists have to go to the regular activity areas of animals in person, track the radio signal on foot and make record. In contrast, the drone can fly following the radio signal and collect the data and image more quickly, so that the scientists can track more animals and acquire more data.

Be against the forest fire

Thermal imaging cameras can also be used in investigating forest fires, avoiding the expansion of fires to cause the serious result. With the help of drones, people can make the quick reaction and control the fire easily.

But the drones can make more contributions to the forest fires. Till now, the firemen have always taken the planes or helicopters to observe the fires. Unfortunately, the firing areas are full of danger, such as the collision of several aircraft in a limited space. The drones can renew the the observation measure and guaranteed the safety of pilots and firemen.

Of course, if the drones are not the only equipment, the drones should cooperate with the aircraft very carefully and precisely.

Drones protect future

Undoubtedly, the drone has changed lots of fields, from estate selling to military activities. Recently, the drone has made contributions to ecological preservation areas and biological field. Now that the ecological protection has not made so much progress, the drone tech would definitely become a popular auxiliary.And also the UAVs flight time is a very popular industry, Gens ace &Tattu lipo battery has a few of reputation in the UAV field, if you interested, you can pay more attention to Gens ace 2s lipo battery and Tattu smart battery.

What’s the difference between NI-MH batteries and lipo batteries

Ni-mh batteries A nickel–metal hydride battery, abbreviated NiMH or Ni–MH, is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxyhydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium. A NiMH battery can have two to three times the capacity of an equivalent size NiCd, and its energy density can approach that of a lithium-ion battery.

5000mah lipo 2s Lipo batteries A lithium polymer battery, or more correctly lithium-ion polymer battery (abbreviated variously as LiPo, LIP, Li-poly and others), is a rechargeable battery of lithium-ion technology in a pouch format. Unlike cylindrical and prismatic cells, LiPos come in a soft package or pouch, which makes them lighter but also less rigid.

The designation "lithium polymer" has caused confusion among battery users because it can be interpreted in two ways. Originally, "lithium polymer" represented a developing technology using a polymer electrolyte instead of the more common liquid electrolyte. The result is a "plastic" cell, which theoretically could be thin, flexible, and manufactured in different shapes, without risk of electrolyte leakage. The technology has not been fully developed and commercialized and research is ongoing.

The second meaning appeared after some manufacturers applied the "polymer" designation to lithium-ion cells contained in a non-rigid pouch format. This is currently the most popular use, in which "polymer" refers more to a "polymer casing" (that is, the soft, external container) rather than a "polymer electrolyte". While the design is usually flat, and lightweight, it is not truly a polymer cell, since the electrolyte is still in liquid form, although it may be "plasticized" or "gelled" through a polymer additive.These cells are sometimes designated as "LiPo"; however, from a technological point of view, they are the same as the ones marketed simply as "Li-ion", since the underlying?electrochemistry is the same.

(1) Weight

In each cell of the gens ace 3s lipo battery voltage , the NiMH is 1.2V, while the lithium battery 3.6V, lithium battery voltage is its 3 -fold. The same type of lithium battery weighs lighter than the nickel-metal hydride batteries . We can see that each different weight battery itself , but because of 3.6V lithium battery high voltage, when the output voltage of the same so that a single battery pack can reduce the number of third leaving after forming the battery weight and volume reduction .

(2)Memory effect

NiMH batteries have memory effect . Therefore, regular discharge management is also required. This periodic discharge management belongs to the fuzzy state to be treated , even some without the right knowledge discharge ( or a few times each discharge after discharge are due to different companies vary ) this cumbersome discharge management when using NiMH batteries can not be avoided . Relative lithium batteries because no memory effect, in a very convenient and simple to use . It is completely without regard to how much residual voltage , direct can be charged , the charging time can be reduced naturally .

(3)Self-discharge rate

NiMH batteries from 25 to 35% (January) , lithium batteries from 2 to 5% (May). Thereby obtained , the rate of self-discharge NiMH batteries much higher than lithium .

(4)Charging

Nickel-metal hydride batteries and lithium batteries can not overcharge resistance . Therefore, the nickel-metal hydride battery constant current charging PICKCUT control mode at the highest charging voltage , charging stops continue as the best way of charging . The lithium battery using constant current, constant voltage charging mode is best.

(5)Application

NiMH batteries : consumer electronic products, remote control toys , hybrid vehicles , renewable energy systems ; Lithium Battery: cell phones, laptops, power tools, electric vehicles, backup power lights , small household appliances.

The basic knowledge of Lipo battery

For example: a 3s 11.1v 25c 2200mah lipo battery
3s：three cells in series
11.1V：3.7*3=11.1V
2200mah：the capacity of the battery
25c：the discharge rate

About voltage

3.7V voltage does not mean that when the battery is fully charged, for lithium-ion battery, the general voltage after full voltage reaches 4.2V,so 4.2*3=12.6V for a 3S battery.

Actually,the real voltage of a cell is 2.75~4.2V.the capacity signed on a battery is how much we got when the battery discharges from 4.2V to 2.75V.So all the remote control model aircraft with lithium-ion battery also must be used within the voltage range of 2.75 ~ 4.2V.Once the lithium-ion battery voltage in remote control model aircraft is lower than 3.7V,we called it over discharging(the damage for battery is fatal),It will cause puff phenomenon,chemical liquid inside will has crystalline polamer,and the crystal may penetrate the inner structural layer caused by a short circuit,will also greatly reduce the battery capacity and discharge rate, so that the battery use value greatly reduced.So good habits is the only way to increase battery life!When the lithium-ion battery voltage in remote control model aircraft is higher than 4.2V,we called it over charging.That will cause intense internal chemical reactions.It easily be exploded if you continue to charge the battery.So no matter overcharge and over-discharge of lithium batteries will have a devastating injury.Therefore, we recommend using the safety standards of regular charger to charge the battery while the charger is prohibited unauthorized alterations, which may result in very serious consequences!

About capacity and discharge rate “C”

Battery capacity to mah (mAh) as a unit, discharge rate in units of C.Regarding “C”,for example,1C means with 1C discharge rate,the battery can last work for one hour.

All in all, the smaller of the discharge rate, the longer the battery discharge time.So when you buy a battery,you cannot just check the discharge rate.A small discharge rate battery also may have large discharging than a large rate battery.Because it is also associated with the battery capacity.It means that a bigger discharge rate have a stronger life vitality.The battery in a small discharge rate will be scrapped a few times.

About charging

A.the charging current:charging current is generally located between 0.5-1c.Recommended not to exceed 1 c(it is C not A)

B.the charging voltage:charging voltage shall not exceed the limit voltage (4.20V / single cell).The maximum limit charging voltage is 4.25V for each cell. (Prohibited the use of straight recharge your battery,otherwise may cause overcharge the cells.Users undertake all the consequences due to an error using battery.)

C.temperature of charging:The battery must be charged in prescribed ambient temperature range of product specifications , otherwise the battery vulnerable to damage.
When find the battery surface temperature anomaly (refer to the battery surface temperature exceeds 50 ℃), you should immediately stop charging.

About discharging

A.discharging current:the discharge current must not exceed a predetermined maximum discharge current.Large current discharge capacity will lead to the sharp decline in the battery and cause overheat and swelling.

B.discharging temperature:the battery must be discharged within specifications specified operating temperature range.When the battery surface temperature exceeds 60 ℃, it should suspend use until the battery is cooled to room temperature.

C.over discharging:over discharging the battery will cause devastating damage, so the discharge can not make the best single battery voltage is lower than 3.7V(lipo 3s voltage).

About stock

The battery should be placed in cool storage environment, long-term storage battery (more than 3 months), it is recommended at a temperature of 10-25 ℃ and low temperature non-corrosive gas environments.In the long-term storage,every 3 months ,battery should be charged and discharged for maintaining its activity, and to ensure that the voltage across each cell within the range of 3.85V.

My inspiration from uav

The unmanned aerial vehicle (uav) is real a hot news now, media editors also in naturally follow suit hype unmanned aerial vehicle (uav). Generally speaking, the news the hype in the two aspects of content: 1, unmanned aerial vehicle (uav) is very cheap, ordinary consumers can buy. 2, unmanned aerial vehicle (uav) is very powerful, it is a legendary weapons, can eliminate the terrorists such as ants.

"I want to fly higher"

The relative height of flight for the performance of the common uav users are not important, for most purposes are fly in low altitude and even "stick", even aerial couldn't fly too high, because you can not see the ground clearly when you fly too high. But the flight altitude for the purpose of the plateau region is a very important parameter.

The air in high altitude is thin, on the one hand, it will drop the efficiency of the propeller ; On the other hand, it will drop the efficiency of power system. The fuel power unmanned aerial vehicle (uav) generally use the naturally aspirated two-stroke engine currently , with the air of the thin air intake reduced efficiency, dynamic nature also will drop at the same time, because the boiling point of pressure drop in gas also drops, to a certain height will boil although in normal temperature.

"I want to fly farther than ever"

The majority of users concerned about the uav flight activities of the radius, this is also a important indicator. But flying range can not bigger as you want, there are two aspects restricting the unmanned aerial vehicle (uav) flight radius : mechanical limit radius with radio control of the plane.

Because of Unmanned aerial vehicle (uav) itself limitation of life, its flight radius is limited. Especially electric rotor, the mission flight time is only about 20 minutes, and then consider the time of land and take off, flight control radius is generally at about 1 km.

Some people think of 3g or 4g mobile network can used to implement similar via "star" effect, but it is a pity that even leaving high price of data traffic, there also have a problem on its feasibility. On the one hand, the planar maps for mobile network is the base station of a circle round the honeycomb, junction signal-blind area,it is obvious during flight; On the other hand, from the three-dimensional space, mobile network based on base station signal tower as the center of umbrella cover down, mobile network signal work well in the earth's surface, even better in the blind area in the air.

“I want to fly longer"

There is no doubt that flight life is a very important index for unmanned aerial vehicle (uav). In many cases, for the mechanical part of unmanned aerial vehicle (uav) itself, the radius of restricting the unmanned aerial vehicle (uav) flight relative height is the most important factor.
normally: no matter for a uav or a man-machine, energy is the main restriction.

For electric uavs, the life of 5000mah lipo battery is even limit. Especially for multiple rotor, due to the response of the motor quickly and easy to control, electric is the ‘Gospel’. But on the other hand electric is an enormous problem that restrict its battery life.

As the carrier of electricity is the 3s 11.1v lipo battery, but the weight of battery is heavy, so the increasing batteries wii not increases the power, but can be seen as a function extremum problems.

"I want to fly no matter rain or shine"

Can uav resist wind?

The resistance of wind for uav is relatively good, because of its low center of gravity and lifting point on the top, even if the wind is big,it also may not be a problem. Windy, of course, the risk will increase , just like if the road is too bad even tanks will afraid of tipping.

Can uav prevent the rain?

Of course not!the electronic equipment of uav, especially of the steering gear, calorific value is big, the better rain-proof the worse heat dissipation. So even the oil helicopters can only fly shortly in the rain,you can fly to return if it rained suddenly but do not try to fly in the rain.

The differences between Smart Battery And Ordinary Battery

The DJI new-released M600 brings big breakthrough to the all UAV Area. Not only the A3’s self-adaptive flight systems and new RONIN-MX is , but also the pretty long flight time supported by six smart batteries.
It introduces that a customized battery management system and power distribution board allows all six batteries to be turned on with one button press, and keeps the system in flight in the event of a failure of a single battery, and allows users to check the battery status in real-time during flight.
As we all know, M100 has adopted smart batteries to support the big heavy device for more professional aerial photography and longer time and distance using. Then what are the differences between Smart Battery and Ordinary Battery, why they are more and more widely used in the electronic ndustry?

1. Definition

A smart battery/A smart battery system(SBS) is a rechargeable battery pack equipped with a built-in battery management system. The smart battery can internally measure voltage and current, and deduce charge level and SoH (State of Health) parameters, indicating the state of the cells, calculated and predicted information to its SMBus Host under software control.
A basic SBS including 3parts:System Host,Smart Charger and Smart Battery.

1.1 Advantages

Ordinary Battery

Ordinary Batteries are illusive and do not exhibit visible changes as part of usage from both the user's and the equipment's perspective. It looks the same when fully charged or empty, new or old and in need of replacement. A very big defect is that they represent an unpredictable source of power.

Firstly, a user has little knowledge that their battery is about to run out or how much operating time is left.

Secondly, equipment powered by the battery cannot determine if the battery, in its present state, is capable of supplying adequate power for an additional load (such as spinning up a hard disk) or not.

Smart Battery

The Smart Battery presents an ideal solution for many of the issues related to batteries used in portable electronic equipment.
The Smart Battery provides the user with accurate state of charge information along with an accurate prediction of the remaining operating time.

It also Provides state-of-charge and full charge capacity; reflects capacity estimations; records battery history; including cycle count, usage pattern, maintenance requirements, max error, etc; configures charger to the correct algorithm; reminds user of periodic service; protects 7.4v lipo battery from unauthorized use; and to prevent accidental system cut-off.
This is why smart battery is more and more popular and widely used.

An excellent smart battery brand-Tattu plus, also have all these advantages when using on your drones.

1.2 Charger

Ordinary Batteries chargers : It must be individually tailored for use with a specific battery size and chemistry and may cause damage if used on another battery.

Smart Battery Charger: It periodically communicates with a Smart Battery and alters its charging characteristics in response to information provided by the Smart Battery（2s 7.4v lipo battery）.

1.3 Defects

The Smart Battery will add 25% to the cost when compared to a Ordinary Battery.
It complicates the charger, most chargers for intelligent batteries are hybrid and also service for non-intelligent batteries.Requires periodic calibration.
Compared with the Smart Battery’s disadvantages, it has more and valuable features.We believe in the future, people will creat more progressived technology on Smart Battery and overcome the price and other problems step by step.
