Description
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

Filtering, inversion, rectification, energy storage, electric discharge form high voltage electric energy pulse, then are transmitted to ignition electric nozzle through firing cable.Circuit is normal
When work, the high voltage electric energy pulse signal that electrical energy pulse detection sensor 3 will test transmits control processor 1.Control processor 1
After judging that signal is normal, control signal is not issued to control switch 2, control switch 2 keeps default two identical function moulds of access
One in block, circuit is made to keep work.When a certain functional module breaks down, the high voltage electric energy arteries and veins of the end of firing circuit
Punching will abnormal or nothing, when electrical energy pulse detection sensor 3 detect high voltage electric energy pulse it is abnormal or without the case where after, by information
Pass to control processor 1.Control processor 1 carries out differentiation confirmation to signal, after discovery signal is abnormal, issues control letter
Number, pass to control switch 2.Firing circuit inputs at different levels are switched to two identical function moulds by fixed sequence by control switch 2
Another in block, until detecting that high voltage electric energy pulse is normal, no control signal is realized and is automatically repaired function.
The present embodiment, the redundance by carrying out every kind of functional module in igniter design, and in every kind of function
Independent control switch 2 is arranged in the input terminal of module, from every kind of functional module, respectively to select a functional module access job logical
Road；By the way that detection sensor is arranged in firing circuit end, igniter operational module state is automatically parsed, and automatically control control
The switching that switch 2 carries out functional module is made, makes igniter when inner function module breaks down, can be realized functional module
Automatic switchover, isolated fault functional module, connect normal function module, realize being automatically repaired for igniter, improve a little
The reliability of fiery device saves maintenance time and maintenance cost in life cycle management, and igniter can be improved
Service life；It still can group when damaging the multiple functional modules of igniter by one by one, successively switching for control switches 2 at different levels
At a complete active channel, the function of igniter is realized, further improve the reliability of igniter.
