Description
Technical field
The present invention relates to unmanned plane application fields, and in particular to a kind of storage of unmanned plane light is filled wireless charging stage apparatus and filled
Power technology.
Background technique
The patrol worker of high pressure overhead power line acts on safe and stable, the efficient operation to ensure power grid, but high-pressure frame
Empty transmission line of electricity generally will across each region distribution, place terrain environment is more complicated severe, and transmission line equipment exposes for a long time
Outdoors, conducting wire, lightning conducter, insulator, fitting, due to the long term of various power, generate tower, mill after long-play
Damage, it is stranded, corrosion, overheat situations such as, insulator there is also by broken by lightning, branch cause high pressure drain the oil and insulation ag(e)ing and
Lead to transmission line of electricity accident, shaft tower has be tampered equal fortuitous events, it is necessary to handle these situations in time.Tradition by manually by
The operation mode of base shaft tower inspection, inspection heavy workload, complicated geographical environment affect patrol officer's life security, backwardness
Manual inspection mode consumes a large amount of man power and material, therefore is necessary with unmanned plane inspection.
Since battery technology and tradition fill the limitation of power supply technique, make unmanned plane cruising ability, flexibility, convenience etc.
How flexibly, easily the development of aspect is restricted, become one during Development of UAV for unmanned plane electric energy supplement
A important developing direction and letter problem to be solved.In order to solve this problem we arrive wireless power transmission technical application
On unmanned plane charging technique, the unmanned plane wireless charging technology based on wireless power transmission mode, the electricity of unmanned plane charging are proposed
It can source.
Summary of the invention
The purpose of invention is to keep its charging convenient in view of the above-mentioned problems, providing a kind of storage of light and filling wireless charging device, energy
It is suitble to various landform and provides charging service in the position in mountain area or separate city, is passed through by solar panel power generation
After charge controller, it is stored in lead-acid battery group, then by being conveyed to coil after discharge controller and inverter, nobody
Machine is charged by the electromagnetic coupling between coil, while can be recycled, and is multi rack time unmanned plane charging, is solved significantly
Unmanned plane is continued a journey problem.
In order to achieve the above objectives, invention, which uses a kind of light of following technical proposal and stores up, fills wireless charging stage apparatus, the party
Method uses following steps:
1. the wireless charging device that light storage is filled needs solar panel to generate electricity, convert solar energy into electrical energy, stores up
There are in solar battery.
Be stored in solar battery 2. preferred described, due to it is high when the output power of photovoltaic power generation is unstable when it is low,
The voltage for being added to battery both ends is also unstable, so we need to carry out DC pressure stabilizing, then could charge to battery,
Otherwise, battery feed meeting reverse phase flows into DC voltage regulator circuit.When solar energy charges to battery, it is necessary to be walked by two
Suddenly, first, by DC-DC conversion circuit, by voltage stabilization in 14V, level used in this system is 12V storage battery, in order to guarantee
There is certain voltage drop, charge power supply must be made slightly larger than storage battery voltage rating.After boosting, need by charge control electricity
Road, charging control circuit are a comparison circuits, and voltage after battery voltage is greater than buck works as electricity then without charging
Bottle voltage is less than the voltage after buck, then charges.During the charging process, by control circuit, electric current can be carried out
Sampling, by control means, in a certain range by current control, can guarantee in this way charging current will not because of excessive and
Destroy level.
3. preferred, described to be stored in battery, the battery refers to lead-acid battery, on the one hand considers cost,
Another aspect lead-acid battery is easy to control.
4. preferred, described to be stored in lead-acid battery, the lead-acid battery is small lead-acid battery, can be placed in and fill
In the shaft tower of electric installation, reducing occupied space simultaneously can also protect battery.
6. preferred, the charging modes two-stage charging device carries out battery using constant current at the initial stage of charging
Charging, this stage utilization rate of electrical height can be filled with 60% or so electricity to battery, will prevent constant-voltage charge initial stage by
In the excessive influence to battery of charging current, this charging stage accumulator voltage can constantly rise；When the end voltage of battery
When rising to a certain setting value, it is switched to constant-voltage charge mode from constant current mode, charging current constantly subtracts in the stage that recharges here
Problem that is small, thus can preventing constant-current charge latter stage from causing battery temperature rise excessively high since charging current is excessive.
7. preferred, the Wireless charging coil is to be wound into disc type by copper wire, is placed on charging platform.
8. the preferred wireless charging system, the wireless charging system pass through induction wireless charging mode.
9. induction radio energy transmission system includes two parts of transmitting terminal and receiving terminal, lead to overcoupling mechanism
(being made of transmitting coil and receiving coil) is electric energy by transmitting terminal wireless transmission to receiving end.
1. push-pull type high-frequency inverter
The main function of high-frequency inverter is that direct current is converted into high-frequency alternating current.Due to this project use it is wireless
Electric energy transmission system is based on magnetic resonance mode, and system operating frequency considers switching device institute usually in MHz rank
Influence etc. of the voltage, current stress and load variation that can be born to high-frequency inverter working condition, this project is inverse in high frequency
Become link selection and uses push-pull type high-frequency inverter.
2. coupling mechanism
In order to guarantee that electric energy high efficiency of transmission, this project use the lotus root based on magnetic resonance mode under the conditions of weak lotus root is closed
Close mechanism.Since this project high-frequency inverter is push-pull type, belong to current mode driving source.According to the basic theories of circuit theory,
Current mode driving source does not allow current interruption, therefore the simple transmitting coil of Ou He mechanism is compensated using parallel resonance.According to
Mutual inductance lotus root is rationally discussed, and the receiving coil of Ou He mechanism influences lesser series resonance compensation using on prime coil parameter.
Therefore, the Ou He mechanism topology of this system is PSSS type topology.
3. power regulation link
Can be for loading the direct current used in order to which the high-frequency alternating current for picking up receiving coil stone is converted into
System picks up end and needs to be added power regulation link.Shown power regulation link by capacitor filtering full-bridge can not control rectifying circuit and
BUCK voltage-dropping type adjusts circuit composition.
Compared with prior art, it is the advantages of invention: has been laid out the installation site of wireless charging device, by lead electric power storage
