There's a breakthrough of
UAV lipo battery.
In the beginning of this year, the first domestic high mobility X8
multi-rotor drones with 7*24 hours' flight time was release in Chuangzhi
Technology Center, Shanghai, China. This drone is called "skyhook" and
adopts irregular ground power transmission system to support the
continuous flight. It can carry visible light zoom camera, infrared
camera, airborne radar and communication antenna to supervise the
security, deal with emergency danger and control the traffic. Those are
all the impossible missions for the consumer level drones among the
market.
the breakthrough of flight time
Previously, the flight time mainly hinders the drone scene
application. Skyhook makes the continuous flight come true. Compared
with the consumer level drones, Skyhook uses a suit of power supply unit
form the ground with the power transmission system, communication
signal and a cable made of fiber that can connect with the cars or other
fixed device on the ground. All of those ensure that the drone can be
mobile can work continuously.
TATTU is remarkable in the field of battery for drones. The ultra-long flight time, smart battery
and protection of low voltage are all the strengths. In the storage,
compared with the other battery, the Tattu battery can stop discharging
once the voltage reaches 3.5V and self-protect(lipo battery 11.1v 2200mah).
In addition to the flight time, the perception and identification is another main problem for drones.
There are three measures to realize the perception and identification.
First, depend on the extra sensor, the radar, because it is hard for
drones to fly safely in the shared areas without people's supervision
and control. Second, identify the object by the drone's camera, which
need strong computation ability. Finally, a traditional computation,
which need the drone designed to identify or escape the threat by the
precise computation, and comprehend how the object is identified while
moving. Skyhook adopts that carrying different devices such as infrared
camera and laser radar 3D scanning topography, and analyzes by the
returned images.
No matter which measure, the key is to let drones know their
surrounding, which is very helpful, even though the application
scenarios are very limited. For example, they can identify whether there
is hole on the frozen roads, find the fires while patrolling in the
forest, and find the footprints of the missing climbers.
The diversity of application scenarios
For next steps, some company will research how to carry different load
to accomplish tasks according to the application scenarios. For
example, the forestry has comparatively low automation rate, and the
drones can fly for patrol 24 hours instead of labor. Another application
scenario that can be imagined is that in the disaster of Tianjin
explosion, drones can be used to test the temperature, gas composition
and microarticle in the air. Also, with the visible light and infrared
camera, it can search the signs of life.
In recent years, drones have been firstly applied in the
anti-terrorist, drug control, traffic dispersion, fire-fighting and
other safety tasks. The quantity of purchase has been increased. In
2014, the public security organization has purchased more than 60
drones, and until the third season, 2015, the public security
organization has purchase over 300 drones, which is five times more than
2014.
Drones have developed dramatically from civil use to commercial use.
Drones also applied in agriculture irrigation. The drones can irrigate
40 times faster than manual irrigation. Using the microwave radar,
drones can scan the ground in real time, keep a suitable distance and
control the volume of liquid. It can fly 8 meters per second, and cover
the crops with liquid evenly. It can switch the mode among fully
automatic, half-automatic and manual operation, and has the property of
dust protection, waterproof, corrosion resistance. Furthermore, it can
fold.
Apart from the agriculture, the traditional geography has taken
advantage of the professional drones, such as monitoring weathering,
observing the change of river and glacier. The archaeologist and
historian are using the drones loaded with common digital cameras to 3c
modelling and restore the scene of ancient architecture relics.
The wide range of application brings new trouble for drones. The
drones have the characteristics of low altitude, low speed, small
objective, so they are hard to supervision, detect and dispose,
especially the prevention and control. It need further observation and
research that how to regulate this safety factors, since illegal
photography or delivering drugs is a countless phenomenon.
