Description
Technical field
The invention belongs to IGNITION CONTROL technical field, particularly relate to a kind of ignition power being applied to electric detonation device
Road.
Background technology
Along with developing rapidly of electronic technology, techniques intensity and the function of missile equipment increase day by day, electric exploder
Part has been continuously available extensive application on guided missile, and is in considerable status.Point such as rocket engine
Fire；The supercharging of liquid engine propellant, the startup of electromotor, turn level；Stage Separation of Missile；Warhead
Ignition etc., all need to use electric detonation device.Can electric detonation device reliably and securely work, and flies guided missile
Row success or failure have directly impact, and bullet otherwise can be caused to ruin the major accident that people dies.The application of electric detonation device is special
Put and use conditional decision when its firing circuit designs, in addition to meeting conventional technique and requiring, go back
Reliability and safety requirement should be met, it is ensured that electric detonation device is when igniting, and firing circuit must be accurate
Ground power supply, makes electric detonation device detonate in good time, and any feelings outside the predetermined duration of ignition and igniting place
Under condition, electric detonation device not because of artificial, components and parts and circuit, and the impact of other random factors and rise
Quick-fried, cause peril to occur, jeopardize the safety of operator, place and guided missile.
In the technical literature " cruising missile design of electrical system " that Yuhang Publishing House announces, to electric detonation device point
Ignition circuit design description is mentioned: electric detonator is not when working, and input should add short circuit plug ground connection；In electric detonation
In pipe firing circuit, it is necessary to have multistage insurance, existing machine insurance, there is again electricity insurance, this what insurance phase
The most independent, but condition each other.
Although more design method demonstrates certain feasibility through model test, but there is problems in that
Electric detonation device is implemented short-circuit protection by application short circuit plug, is to be realized, reliably by electric connector docking
Property is higher；But special lid need to be offered on bulkhead and carry out dismounting or the installation of short circuit plug, and every time
Need staff's manual operations, be unfavorable for applying in the task comparatively short to time requirement (as launched battle array
Ground test/launch) or guided missile vanning long term storage.
When two groups of normally opened contacts of the single relay of employing, control the positive and negative firing circuit of electric detonation device respectively
Break-make, complete electric detonation device igniting time, if the two of this relay groups of normally opened contacts are not operating normally,
Or due to relay itself exist fault cannot adhesive time, may result in firing circuit cannot normal ignition；
If two groups of normally opened contacts of the single relay being connected on respectively in the positive and negative firing circuit of electric detonation device are different
Step work, then can cause the igniting sequential failure of whole electric detonation device group or sequential abnormal.
When using two respective two groups of normally opened contacts of relay, after carrying out parallel connection, control electric detonation device respectively
The break-make of positive and negative firing circuit, when completing the igniting of electric detonation device, although achieve the double superfluous of firing circuit
Remaining control, it is possible to resolve when the normally opened contact of single relay can not be operating normally, or relay existence itself
Fault cannot adhesive time, cause firing circuit cannot the problem of normal ignition, if but two relays do not have
Carry out action according to synchronic command, then present in the firing circuit for single Control, relay is normal
The problem opening the asynchronous work in contact, is present in this circuit too.
Therefore, the electric detonation device point reliable, effective of adaptation following IGNITION CONTROL technology development need to be furtherd investigate
Fire control circuit.
Summary of the invention
In view of this, the invention provides a kind of firing circuit being applied to electric detonation device, this firing circuit was both
When normality, electric detonation device can be carried out short-circuit protection, it is ensured that the laden safety of electric detonation device, again can
The most operationally, electric detonation device is removed short-circuit protection, implements IGNITION CONTROL effective, reliable.

Beneficial effect:
(1) present invention can either send control signal accurately, reliably, completes the igniting to electric detonation device
Control；When non-ignition operation execution can be effectively ensured again, the safety of electric detonation device.The present invention sets at circuit
On meter, use integrated planning, timesharing application design philosophy, application electromagnetic relay same group of mutual exclusion normally opened,
Normally-closed contact short-circuit protection circuit and negative sense firing circuit to electric detonation device respectively carries out path control, it is ensured that
At any time, circuit have and only have a kind of state effectively (or effectively implement the IGNITION CONTROL of electric detonation device,
Or electric detonation device is carried out effective short-circuit protection).
(2) Redundancy Design is combined with backup design, implements to control to negative sense firing circuit.Will just
After same group of mutual exclusion normally-closed contact parallel connection of two normally opened contacts in ignition control circuit, with negative sense IGNITION CONTROL
Same group of mutual exclusion normally-closed contact of the normally opened contact in circuit is connected, and electric detonation device is implemented short-circuit protection.
So, the harm that may bring after both having avoided one group of contact failure, same group of electromagnetic relay of application is normal again
Open the mutual exclusion characteristic of contact, normally-closed contact, it is ensured that any time electric detonation device has and only has a kind of effectively shape
State exists.
(3) forward firing circuit is used the method for designing of Redundant Control.By two electromagnetic relays two
Together, the path implementing forward firing circuit controls in group normally opened contact connection in series-parallel.As such, it is possible to effectively keep away
After exempting to apply two groups of normally opened contact parallel connections of single electromagnetic relay, or a group of two electromagnetic relays is normally opened
After contact series, when implementing path controls, owing to the reasons such as electromagnetic relay inefficacy cause normally opened contact time delay
Guan Bi or do not close, and then affect electric detonation device on time, the problem of reliable ignition, improve igniting reliability.
