Description
Technical field
The invention belongs to unmanned air vehicle technique field, more particularly to a kind of multi-rotor unmanned aerial vehicle Universal lithium-cell dump energy
Forecasting system and method.
Background technology
Gyroplane be it is a kind of using autorotation to produce the rotary wing aircraft of lift, between helicopter and aircraft
Aircraft；According to the motionless propeller equipped with varying number of species, there is VTOL, can low speed low-latitude flying, simple light
Ingeniously, it is easy to the features such as hidden.In recent years, with the maturation of gyroplane items technology, gyroplane starts more and more to be weighed
Depending on.For at present, gyroplane is mainly made up of dynamical system, control system, execution system and fuselage etc..It is current most
The dynamical system of gyroplane be all to use lithium battery as power resources.Due to more gyroplanes with lithium battery using increasingly
It is more.Present in the market is badly in need of a kind of device that can quickly judge battery dump energy and remaining battery service life.It is existing
The unmanned plane of in the market generally determines dump energy using voltage measurement mode.In new battery still more accurately.But
It is that this mode precision of prediction declines much in use for some time.During the use of battery, because switchgear is big
The impact of electric current.Electrode is burnt so that effective area reduces.Electrode substance comes off so that the impurity of electrolyte increases, pure
Degree reduces the battery in charging process and bulging slowly occurs.Charge efficiency occur is reduced, and capacity is reduced.Direct phenomenon is in short-term
Between just it is fully charged, but the electricity consumption time shorten.Or for a long time can not be fully charged, and the electricity consumption time also shortens.These phenomenons
Can slowly occur in battery use.It is not very big, but true for flight equipment that the decline of capacity influences for ground installation
It is fatal.
In summary, the problem of prior art is present be：The unmanned plane of in the market is generally using voltage measurement mode come really
Determining dump energy, precision of prediction can be reduced substantially in use for some time.
The content of the invention

Start working.
Further, after the Forecasting Methodology booting computer of the multi-rotor unmanned aerial vehicle Universal lithium-cell dump energy, computer bullet
Go out inputting interface, it is desirable to which user inputs battery brand name, model, voltage, capacity, usage time respectively.Inputted according to client
Battery parameter, started working after being confirmed by lithium battery detection mouth to battery size.
Further, the computer carries out pulsation electric discharge with 10 times of high currents, 5 times of medium currents and normal current respectively；And
And recording voltage and current curve, by continuously detecting Voltage Drop curve and current curve, battery is calculated according to known resistance
Internal resistance.The ratio for calculating available power and general power draws discharging efficiency group；Inquiry comparison is carried out using data with existing storehouse, is obtained
Data interval where going out cell discharge efficiency, predict the dump energy and discharge current and the relation curve of time of battery.
Another object of the present invention is to provide to provide one kind using the remaining electricity of the multi-rotor unmanned aerial vehicle Universal lithium-cell
The multi-rotor unmanned aerial vehicle of the Forecasting Methodology of amount.
The present invention can obtain accurate lithium battery dump energy.Belong to common apparatus, according to selected lithium battery
Group model, which carries out detection, more can accurately predict dump energy.By these prediction data, obtained after being substantially discharged to battery
Go out precision of prediction reaches measuring electric quantity more than 90%.There is presently no the product for predicting this battery dump energy.The present invention
The market vacancy is filled up so that the flight of unmanned plane is preferably ensured
