Description

A kind of igniter being automatically repaired
Technical field
The present invention relates to a kind of igniters.More particularly to a kind of igniter that can be automatically repaired.
Background technique
Igniter is the important component of engine igniting system in the tracker actions such as aircraft, automobile, effect Be by the tracker actions such as aircraft direct current or AC power source be transformed into high voltage electric energy pulse, be transmitted to a little by firing cable Thermoelectricity mouth generates high energy electric spark, the indoor burning mixture of ignition engine burning at the ignition end of ignition electric nozzle.
At this stage, it by taking the igniter on aircraft as an example, is mainly made of firing circuit and shell, wherein such as Fig. 2 Shown, firing circuit includes filter module, inverter module, rectification module, energy-storage module, boost module, discharge module.Shell Generally pass through the enclosure space of melting welding or the formation of soldering.All functional modules are assembled into sealing or closed housing parts It is interior, it is connect by the height press contacts device on shell with firing cable and aircraft power supply.The working principle of firing circuit are as follows: The electric current of aircraft power supply is transmitted to filter module by the low pressure contact device of engine cable and igniter, through filtering mould After block filtering, high-voltage alternating pulse is converted to by inverter module, the rectified module of the pulse charges to energy-storage module: working as energy storage After voltage in module reaches required value, sample circuit generate sampled signal to inverter module, end inversion: control of discharge by Frequency pulse is determined in independent discharge module output, and control the switch of discharge module: the electric energy on energy-storage module is transmitted through discharge module It to boost module and is converted to and device is contacted by the high pressure of igniter after electrical energy pulse is transmitted to firing cable, then by lighting a fire Cable transmission generates electric spark in the interelectrode semiconductor surface electric discharge of ignition electric nozzle, then repeats this mistake to ignition electric nozzle Journey.Disadvantage is that: in the igniter course of work, due to consolidating for the function component in its functional module or module There is reliability impossible 100%, component failure all will lead to ignitor failure in any one functional module or module, make Ignition system fires failure, global reliability are relatively low: meanwhile, function component uses the longevity in certain functional modules or module Life is low compared with function component in other function module or module, is not able to satisfy igniter life-cycle requirement, it is necessary to midway It carries out large repairs, function component in replacement service life shorter functional module or module, and igniter is mostly to pass through weldering The sealing to be formed or closed structure are connect, field maintenance is poor, it is necessary to return to manufacturing firm and carry out large repairs, lead to life cycle management Interior maintenance time is long, at high cost.
To sum up, igniter in the prior art, it is relatively low that there are reliabilities, and maintenance time is long, at high cost in life cycle management The technical issues of.
Summary of the invention
In order to solve igniter in the prior art, reliability is relatively low, and maintenance time is long, at high cost in life cycle management Technical problem.The present invention provides the igniters that one kind can be automatically repaired.
The igniter that described one kind can be automatically repaired, including firing circuit and shell, it is characterised in that: further include control Circuit processed;The control circuit is made of control switch, control processor and electrical energy pulse detection sensor;The firing circuit Functional module be all made of double configuration, connect again with other functional modules after identical function module is first in parallel;It is described identical Functional module is mounted on control switch in its input terminal in parallel: the control switch is used for the control according to control processor One of them in two identical function modules is switched to the active channel of firing circuit by signal;The end of the firing circuit End is equipped with electrical energy pulse detection sensor, and the high voltage electric energy pulse for exporting to firing circuit detects, and will test letter Breath passes to control processor;The control processor is used for periodic receipt detection information, and is judged a little according to detection information Whether fiery device is normal, and when being judged as abnormal, control control switch successively switches, and when being judged as normal, control control switch is protected Hold current state.
In above scheme, the functional module of the firing circuit is all made of both sides' backup and refers in existing moduleization igniting On the basis of device, firing circuit is formed using two sets of identical functional modules;And identical functional module is by simultaneously Series connection is carried out after connection and forms firing circuit, so that every kind of functional module in firing circuit is all had double redundancy, is made firing circuit Meet the redundance design of intersection on the whole.The identical function module is fitted with control switch in its input terminal in parallel, anticipates Taste how many kind functional module in firing circuit, i.e., how many control switch need to be configured.Control switch is controllable gating Switching device, function can analogize to controlled single-pole double-throw switch (SPDT), by connection control processor, receive control processor Control instruction, realize that gating switching, work that one of them for making in two identical function modules is cut into firing circuit are logical Road.The active channel of the firing circuit refers to the circuit that all operational modules being strobed are linked to be, the composition of the circuit and existing There is single channel firing circuit identical.In firing circuit, when a certain functional module breaks down, the high voltage electric energy of firing circuit end Pulse will be abnormal, therefore electrical energy pulse detection sensor is arranged in firing circuit end, cooperates the judgement of control processor, can To detect in firing circuit whether have module failure, when determining high voltage electric energy pulse exception, then it represents that have more than one function There are failures for energy module, at this point, control processor can then issue control instruction, switch over corresponding control switch, allow standby The functional module of part cuts active channel, and the functional module of failure is isolated, realizes being automatically repaired for igniter.It is described The principle that control control switch is successively switched is: because control processor is periodic receipt detection information, when first It is secondary that control processor controls one of control switch and switches over when detecting that high-voltage pulse is abnormal, when next cycle, It detects when remaining as abnormal, then controls next control switch and switch over, until some period, when being detected as normal, i.e., Control switch state is kept, switching is stopped, on a timeline, different control switches are switched over a sequencing, and The sequencing is preset when being initialization, therefore when firing circuit exception, the switching of control switch successively carries out.Especially need It is noted that sometimes, some or multiple control switches may not be needed to carry out due to the difference of functional module damaged condition Switching, firing circuit is just normally;Sometimes, some or multiple control switches may need to switch repeatedly, firing circuit ability Restore normal.It is accessed using the remaining of control function module respectively and is successively switched, it is ensured that as long as certain function is not present The extreme case that module is all damaged is capable of forming the active channel for meeting firing circuit functional requirement always.
