Description
First, technical field:
The present invention is provided a kind of can belong to aerospace vehicle to the design of day solar battery quadrotor
Energy resource system technical field.
2nd, background technology:
Quadrotor is symmetrically distributed in before body using direct driving force source of four rotors as flight, rotor
Afterwards, left and right four direction, four rotors are in sustained height plane, and the structure and radius of four rotors are all identical, diagonal
Rotor wing rotation direction it is identical, one group turns clockwise, another group of rotate counterclockwise, can thus balance rotor to fuselage
Reaction torque.Four motors are symmetrically installed on the bracket end of aircraft, and support intermediate space lays flight-control computer and outer
Portion's equipment.Quadrotor can freely hover and VTOL, simple in construction, it is easy to control.It is relatively other kinds of to fly
For row device, quadrotor compact conformation can produce bigger lift.These advantages determine that it has a wide range of applications
Field, the various fight functions not only needed with general battlefield, such as the fixed point monitoring to target area is other forces of fighting
Device indicates target etc., it might even be possible to be used as the carrier for delivering weapon.
Quadrotor typically provides the energy by lithium battery, and electric current is provided to four motors, so that motor rotates.
But limited by lithium battery energy density and Flight Vehicle Structure weight, the lithium battery carried on quadrotor is limited,
Again because the energy storage of lithium battery is its unique energy source, so the hang time of quadrotor is necessarily affected.
This short feature of airborne period is into the fatal weakness of quadrotor.In recent years, solar battery technology is developed rapidly, can
So that Application of Solar Energy technology to be combined with flying platform, so as to provide one to solve the short problem of quadrotor airborne period
Plant thinking.
Therefore, by the way that increasingly ripe solar battery technology and to day follower quadrotor will be applied to
On, the invention provides it is a kind of it is day being tracked, solar energy can be made full use of to realize for a long time leave a blank new the four of flight
Rotorcraft design scheme.
3rd, the content of the invention:

After turn signal from sensor, control system will carry out judging to need to drive that orientation according to the signal of sensor
Stepper motor, be then divided into two path control signal export to stepper motor driver all the way control signal driving level orientation stepping
Motor driver, drives the main axis being fixed on support, for realizing the tracking of sunray level orientation;Another road control
Signal driving vertical orientations stepper motor processed drives solar panel relative and holder pivots, for realizing to sunray highly
The tracking at angle.
The solar battery array that described solar module is made up of silicon-based photovoltaic cells.Due to photovoltaic cell
Power loading is depended on nonlinear current-voltage (I-V) characteristic and output characteristics, therefore, referred to as maximum power point
Integral energy utilization ratio of the technology (Maximum Power Point Tracking, MPPT) of tracking to lifting photovoltaic cell
With important influence.So-called MPPT is exactly the electronics that a set of electric current and voltage to photovoltaic cell and energy-storage battery is monitored
The DC/DC converters of device and one group of adjustable gain.By changing gain, MPPT can make the energy obtained from photovoltaic cell
Reach maximum.By the utilization of maximal power tracing device, the maximum power output of solar module can be followed the trail of constantly
