Background technique
In order to ensure priming system mechanisms certain in the product of high-speed motion can work normally, such as missile wing unfolding mechanism, son
Ammunition sheds mechanism etc., needs to verify the functional reliability under its high-speed cruising by ground simulation test.For this purpose, needing
By product be fixed on it is a certain can be to make product carry out high speed fortune in orbit by external thrust on the track of high-speed motion
The dynamic real motion speed with analog equipment.
Currently, the triggering mode for priming system is mainly equipped with copper mesh in orbit, triggering work is provided to product and is supplied
The external power supply of electricity, and recorded in real time equipped with high-speed photography device.Lack a kind of auto-ignition circuit to realize in product
The automatic ignition and data synchronous recording of priming system mechanism of portion.
Summary of the invention
The present invention proposes that one kind during the test can be by the automatic trigger priming system point of external trigger power supply power supply
Ignition circuit to complete the normal ignition function of priming system, while triggering high-speed photography record to reach synchronous recording purpose.
In view of the above problem of the prior art, according to one aspect of the present disclosure, the present invention uses following technology
Scheme:
A kind of automatic trigger firing circuit, it is characterised in that:
The main track of priming system power supply access external data recording device after a resistance R of connecting draws positive terminal and interior
The negative wire of portion's Acquisition Circuit, external data recording device and priming system power supply is shorted by switch K1, after on-test,
Switch K1 is disconnected, internal Acquisition Circuit and external data recording device record data simultaneously；
By the coil input end phase of the main track end switch K2 of external trigger power supply and relay KA1, relay KA2
Even, the negative wire end switch K3 of external trigger power supply is connected with relay KA1, relay KA2 coil output, relay
KA1, relay KA2 energization input meet the anode of priming system power supply, the positive relay termination KA1 of priming system 1, relay
The power supply output end of KA2, negative terminal connect the cathode of priming system power supply, constitute the automatic trigger firing circuit of priming system 1；
Subsequent time-delay relay KTm, the energization input of KTm+1 connect the anode of priming system power supply, subsequent delay
The power supply output end of relay KTm, KTm+1 connect priming system n anode, and m=2n-3, m are the positive integer more than or equal to 1, n be greater than
Positive integer equal to 2, subsequent time-delay relay KTm, KTm+1Coil input end equal contact relay KA1, relay KA2 power supply
Output end, subsequent time-delay relay KTm, KTm+1Coil output connect the cathode of priming system power supply, constitute priming system n
Automatic trigger firing circuit；
When automatic trigger is lighted a fire, switch K2, switch K3 are also turned on, external trigger power supply is connected, at this time relay
KA1, relay KA2 coil are powered, and priming system power supply is powered to priming system 1, after priming system 1 starts power supply, relay
KA1, relay KA2 self-hold circuit keep the coil power supply to relay KA1, relay KA2, and trigger first group of delay
The work of relay KT1, KT2 trigger, after the delay time set by time-delay relay KT1, KT2, priming system power supply
Power supply is powered to next priming system 2, and so on complete the power supplies of from multiple priming systems to entire circuit.
The utility model has the advantages that
The present invention utilizes control relay circuit, is that can reach the function and uniformly of automatic trigger igniting using switch control
The purpose of zero point is recorded, it is simple and effective, it can be universally used in multiple and different products, practicability with higher.
Detailed description of the invention
