Abstract
The utility model belongs to air vehicle technique field, discloses a kind of winged control power supply of small drone, and 5V inputs merge with SERVO inputs after BQ24313 voltage stabilizings after BQ24315 voltage stabilizings to 5.5V, after filtered regulator circuit processing, are again broken down into two-way：5V voltages are directly exported after current-limiting fuse all the way to external equipment；Another way is supplied respectively to fly control master chip and core sensor through current-limiting fuse through MIC5332 voltage stabilizings to 3.3V.In addition the utility model is individually extracted all the way after merging of increasing income to the number biography for needing high current, mitigating the pressure of merging branch also reduces interference of the high current branch to main branch, improve the anti-interference ability for flying control hardware, and it eliminates 0ZCA0035FF2G current limlitings above main branch to design, enhances the autgmentability and tolerance for flying control hardware.
Description
Technical field
The utility model belongs to air vehicle technique field more particularly to a kind of small drone flies control power supply.
Background technology
Flight control system (referred to as flying control) is the core that small drone realizes autonomous flight, to the power supply for flying control power supply
Quality directly affect fly control performance and unmanned plane flight quality.Most of small drone fly control firmly using increasing income at present
Part, and there are some unreasonable places for the Power Management Design for winged control hardware of increasing income, and are mainly reflected in：(1) increase income fly control hardware be by
Input effective source that power supply and SERVO power supplys incorporate all the way, become a new power supply come give whole system power supply, close
And give all devices to power later, that is, large and small load is hung over substantially in the same manner and is merged above branch, it easily generates in this way
Electromagnetic compatibility problem；(2) it is used after the Dual MOS NTHD4102PT1G in electric current by Effective judgement module LT4417
0ZCA0035FF2G carries out current limliting, and limitation electric current is in 350mA, this is completely unnecessary, because electric current is to flow through Dual MOS
NTHD4102PT1G, can bear the electric current of 2A, be then restricted to 350mA and the device all to master control is powered, no
It disclosure satisfy that autgmentability, tolerance, be unreasonable.
It increases income and flies control by all loads all carries on merging branch road, it, can be by power supply noise when the operation of relatively large load
It is transmitted to the importation of other circuits, if the circuit for receiving power supply noise is now in the labile state area of level conversion
Domain then power supply noise may be amplified, and generate impulse disturbances in the output end of circuit, and then may cause patrolling for circuit
Collect mistake.
It increases income to fly to control and limits current to be powered in 350mA and to all devices, when all external equipments work at the same time
When, power may be not enough to drive all load devices, be unfavorable for external expansion equipment；Simultaneously because current limliting is in 350mA,
When power supply continue working is near cut-off current, current-limiting fuse may disconnect if generating fluctuation, cannot be just to fly control
Often work.It promotes power supply output when current limit amplitude can guarantee its work and meets be possible to operating mode.
In conclusion problem of the existing technology is：The existing Power Management Design for increasing income winged control hardware, which exists, easily to be produced
Raw electromagnetic compatibility problem, it is impossible to meet autgmentability, tolerances.
Invention content
In view of the problems of the existing technology, the utility model provides a kind of winged control power supply of small drone.
The utility model is realized in this way a kind of small drone flies control power supply, the small drone flies control power supply,
5V inputs merge with SERVO inputs after BQ24313 voltage stabilizings after BQ24315 voltage stabilizings to 5.5V, filtered regulator circuit processing
Afterwards, it is again broken down into two-way：5V voltages are directly exported after current-limiting fuse all the way to external equipment；Another way is steady through MIC5332
It is depressed into 3.3V, is supplied respectively to fly control master chip and core sensor through current-limiting fuse.
Further, external equipment includes pitot meter, sensor and is connect with MIC5332 by current-limiting fuse.
Further, the core sensor includes MPU9250, MS5611, L3GD20H, FXOS8700CQ and passes through limit
Stream fuse is connect with MIC5332.
Using 5V_Brick as the core power of master control borad, power supply of the SERVO power supplys as high power device, USB power source
As the power supply that master control borad is debugged in USB, part electricity is passed for needing high-power output or being extended to the number of high-power output
The supply in source uses SERVO power supplys.
Core power of the utility model using 5V_Brick as master control borad, electricity of the SERVO power supplys as high power device
Source, power supply of the USB power source as master control borad when USB is debugged, for needing high-power output or being extended to high-power defeated
The supply that the number gone out passes partial power uses SERVO power supplys；Increase income merge after in addition individually extract it is big to needing all the way
The number of electric current passes, and mitigates the pressure of merging branch and also reduces interference of the high current branch to main branch, improves and fly control hardware
Anti-interference ability, and eliminate above main branch 0ZCA0035FF2G current limlitings and design, enhance the autgmentability for flying control hardware and
Tolerance.
When the current fluctuation on circuit is bigger, since the voltage fluctuation Δ U that line-to-line crosstalk generates will increase therewith,
To cause the variation of voltage U.Assuming that the voltage fluctuation Δ U that electric current generates is constant, enabling influences COEFFICIENT K 1=Δs U/U1, K2=Δ
U/U2 then influences the ratio between coefficient K=K1/K2=U2/U1 under different voltages.U1=5V, U2=3.3V are brought into, K=can be obtained
0.66, it is seen that fluctuating the influence of generation can decline to a great extent.In addition physically, also high-power peripheral hardware and master chip etc. are isolated,
It further reduced voltage disturbance.
