Concrete meaning in invention.
As shown in Figure 1, a kind of firing circuit with energy-storage function described according to an embodiment of the invention, the igniting
Circuit includes mainly：First resistor R1, one end ground connection, one end connect the first power supply VCC1, and the other end connects second resistance R2；The
Two resistance R2, one end connect the first power supply VCC1, the other end anode with the positive and silicon-controlled Q1 of capacitance C1 respectively
It is connected；3rd resistor R3, one end are connected with the cathode of capacitance C1, and the other end is connected with ignition signal cathode output end OUT-；The
Four resistance R4, one end are connected with second source VCC2, the other end respectively with the 5th resistance R5, the 7th resistance R7 and triode Q2

Outlet OUT+ and ignition signal cathode output end OUT- are connected with the both threads of engine respectively, when circuit works, meeting
There is initial firing current to flow through the two points, engine will be activated.
Circuit I is charge circuit, is made of second resistance R2, capacitance C1 and 3rd resistor R3.Circuit II is to discharge back
Road is made of capacitance C1 and silicon-controlled Q1.
Firing circuit operation principle is as follows：
First power supply VCC1 is power supply, is provided by unmanned plane accumulator.After first power supply VCC1 is connected, pass through second resistance
R2 and 3rd resistor R3 charges to capacitance C1, and the charging time is about 5 seconds.After charging complete, access I is in stable state, A points
Voltage is the voltage of the first power supply VCC1, and B point voltages are 0V.
D point init states should be high level, and triode Q2 is connected at this time, and C point voltages are about 1.2V, cannot be satisfied controllable
The conducting requirement of silicon, silicon-controlled to be in cut-off state, ignition circuit II can not constitute circuit, also can not just generate initial firing current.
After sending out ignition trigger signals IGN, D point voltages become low from height, and triode Q2 cut-offs, C point voltages become
VCC2, E point voltage increase on year-on-year basis, reach silicon-controlled Q1 turn-on conditions, silicon-controlled Q1 transient switchings, and ignition circuit II is constituted back
Road, to generate initial firing current.
It discharges back in view of after taking off there are unmanned plane but the case where fire extinguisher bomb need not emit, ignition circuit board devises
Road, after the first power supply VCC1 power-off, the electric energy stored in capacitance C1 can be released by first resistor R1 and second resistance R2
The case where putting, also being charged after being powered off there is no ignition circuit board, discharge time is about 10 seconds.
In conclusion size of current of the firing circuit of the present invention independent of power supply itself, even if power supply itself
Electric current cannot be satisfied launch requirements, the storage of electric energy can also be carried out by energy-storage module, therefore can reduce the need to power supply
It asks；The present invention is used as discharge device, reaction speed to be higher by 1 order of magnitude than metal-oxide-semiconductor using silicon-controlled simultaneously, and can be with
It bears high current to pass through, therefore satisfactory initial firing current can be generated in a short time.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
