Currently, using the aircraft of carburetor structure engine on the market, it is both needed in engine starting process using manual
Carburetter choke operation is closed and opens, to control engine starting process.However, in a first aspect, the hair that aircraft uses
Motivation shaft is all connected directly or indirectly propeller, operates quite dangerous using manual switch carburetter choke.
Then second aspect is limited by installation space and use condition, and the engine mounting positions that aircraft the uses more limit is changed
Oily device choke substantially mostly cannot be by directly carrying out opening and closing operation manually.The third aspect, engine operation process
Flameout state is relatively conventional, can not accomplish aircraft flight process engine restarting control using choke flap switch mode is manually controlled
System.
For this purpose, being deposited in the prior art this application provides a kind of unmanned vehicle engine control device and method to solve
Engine can not be restarted automatically, it is inconvenient for operation, reduce and the working efficiency of the equipment of power be provided using the engine
Technical problem.
Embodiment
Referring to Fig. 1, Fig. 1 shows a kind of unmanned vehicle engine control device 100 provided by the embodiments of the present application, nobody
Machine engine control system 100 includes: testing agency 110, servo mechanism 120, control mechanism 130.The setting of testing agency 110 exists
On engine, testing agency 110 and servo mechanism 120 are connect with control mechanism 130, the carburetion of servo mechanism 120 and engine
The choke 150 of device 160 connects.Testing agency 110 is used to detect the working condition of engine, and the working condition of engine is believed
Breath is sent to control mechanism 130.Control mechanism 130 is used for, and according to work state information, judges whether engine is that midway is put out
Fire sends shutdown instruction to servo mechanism 120 if engine is that midway is flame-out.Servo mechanism 120 is used for, and is referred to according to shutdown
Driving choke 150 is enabled to close, so that engine restarting.
By using above scheme, by detecting the working condition of engine, when engine, which is in midway, to stop working, control
Choke 150 is closed, so as to generate negative pressure in carburetor 160 and suck fuel oil, meanwhile, the closing of choke 150 can be with less sky
Gas enters carburetor 160, increases the concentration for the combustion gas that fuel oil is formed in carburetor 160, combustion gas is burnt, Jin Ershi
Existing engine is restarted automatically.Solving engine existing in the prior art can not be restarted automatically, and inconvenient for operation, reduction is answered
The technical issues of providing the working efficiency of the equipment (unmanned plane) of power with the engine, having reached can be with automatically controlled engine
It is restarted automatically, it is easy to operate, it improves and the technical effect of the working efficiency of equipment of power is provided using the engine.Meanwhile
It needs not think to operate, ensure that the safety of user.
As an alternative embodiment, control mechanism 130 is also used to, the work shape sent according to testing agency 110
State information, judges whether engine has been turned on；If engine has been turned on, door open command is sent to servo mechanism 120.Servo
Structure 120 is also used to, and drives choke 150 to open according to door open command, so that engine continuous works normally.Wherein, judge to send out
Whether motivation has been turned on can be determined by judging start to send the combustion gas in machine (carburetor 160) whether to be in combustion state,
Start to send the combustion gas in machine (carburetor 160) to be in combustion state, determine that engine has been turned on, otherwise determines that engine does not open
It is dynamic.
By opening choke 150, the air inlet in carburetor 160 is increased, containing for engine combustion is improved
Oxygen amount, so that the fuel gas buring in engine is abundant, first aspect can make engine normal to continue with sustained combustion
On the other hand work guarantees burning sufficiently, energy-saving and environmental protection.
As a kind of optional embodiment, servo mechanism 120 is also used to, when servo mechanism 120 is in power-off or no signal
When state, control choke 150 is closed.
When servo mechanism 120 is in power-off or when no signal condition, it can determine that engine stops working for a long time or in depositing
State is put, at this moment, control choke 150 is closed, and can protect the air inlet of carburetor 160, and sundries or dust is avoided to enter
To engine interior, engine is protected.
Control mechanism 130 is also used to, and according to the work state information sent according to testing agency 110, judges that engine is
It is no in long-term flame-out or storage configuration, if fruit engine is in long-term flame-out or storage configuration, send instruction of closing the door to servo
Mechanism 120.Servo mechanism 120 is also used to, and according to 150 either on or off of choke described in the shutdown order-driven, is started with protection
Machine.
It is opened or closed to realize that servo mechanism 120 controls choke 150, as an alternative embodiment, nothing
Man-machine engine control system 100 further includes control connection component 140, referring to Fig. 2, servo mechanism 120 and choke 150 pass through
Connection component 140 is controlled to connect.Servo mechanism 120 drives choke 150 in predetermined angle range by driving control connection component 140
Interior rotation turns on or off choke 150 to realize.Specifically, servo mechanism 120 is suitable by driving control connection component 140
Hour hands rotate first angle, then choke 150 can be driven to rotate counterclockwise first angle, wherein first angle belongs to default
Unspecified angle in angular range.For example, predetermined angle range is 0~90 degree, then first angle can be 45 degree, 90 degree etc.,
When choke 150 is in 0 degree, choke 150 is in close state, when the aperture that choke 150 is in 90 degree (is rotated from 0 degree
To 90 degree), choke 150 is in full open position.When first angle is not equal to 0, needle rotates first angle, then can drive
Dynamic choke 150 opens first angle, and then mechanism rotates counterclockwise first angle (from 90 by driving control connection component 140
Degree rotates to 0 degree), then 150 inverse time of choke first angle clockwise can be driven, so that choke 150 be driven to close.
In order to effectively, neatly choke 150 be driven to open or close, as an alternative embodiment, institute
Stating control connection component 140 includes connecting rod 141 and the first rotational structure 142, is provided with first through hole in the first rotational structure 142
