Description
Technical field
The present invention relates to in-line arrangement fuse, especially it is a kind of can safe on-line checking in-line arrangement fuse.
Background technique
In-line arrangement fuse refers to using electronic safety and arming device and the Slapper detonator based on insensitiveness powder charge, is formed
Fuze system without flame proof explosive train.
In-line arrangement fuse is relative to tradition machinery fuse and mechanical-electrical fuze, other than high security, high reliability, Ling Yichong
Wanting feature is to have good testability.Tradition machinery fuse or mechanical-electrical fuze, since solution guarantor's process is irreversible, production assembly
The test of the workflows such as complete solution guarantor, triggering is not can be carried out after the completion.In-line arrangement fuse, will be removable before producing and shooting
Slapper detonator is unloaded to be substituted for after simulation detonator sub-assembly, it can be achieved that comprehensive test of fuse performance.
But install in fuse to body, since what is installed on fuse is actual primer, and do not have the mould that changes the outfit generally
The operating condition of quasi- detonator, it is contemplated that safety cannot be powered up test.I.e. various fuses are once installed to body at present
Afterwards, it not can be carried out on-line testing.
And for some guided missile class high value ammunitions, have under the conditions of self-contained before transmission each component of total system is carried out it is complete
The demand of face test, to guarantee that system function is normal, it is ensured that be reliably completed strike task.Fuze system becomes online survey before transmitting
The blind spot of examination.
The paper that Shen Bo of Xi'an Electro-mechanical Information Inst. et al. was delivered in 2010 " increases CAN for electronic time fuze
Bus selftest module " in, propose that one kind can be measured for four class measurement points such as voltage value, resistance value, time value and switching signals,
The scheme of electronic time fuze functional test is completed when setting by CAN module.The program has certain novelty, but also deposits
Some insufficient: one, since mechanical-electrical fuze solution is protected, process is irreversible, and inquiry solution guarantor's state is not to vital safety
System function is tested；Two, detonator inner walkway just can be carried out after transmitting, and practical significance is little；Three, selftest module increases
The requirement such as system bulk, cost, power consumption reflects volume, power consumption since electronic time fuze security system is not tested in text
Etc. costs it is little, if tested fuse comprehensively, increased volume, power consumption etc. may be larger.
Summary of the invention
The purpose of the present invention, aiming at deficiency of the prior art, and provide it is a kind of can safe on-line checking
In-line arrangement fuse, the program is connect using setting test interface with the key point of each internal component interface, due to electronics member device
Impedance can generate variation after part failure, and then influence the impedance of the test point of component interface, therefore after fuse is packed into guided missile, lead
Control system is played by the testing impedance of fuse test interface, can determine whether most of device (not being isolated device) state whether
Normally, and then judge fuse state and performance.Why inter-module interface testing point is used rather than the external electric interfaces of fuse
Impedance measurement is since the external electric interfaces of fuse are typically provided with various isolating devices, to the anti-of internal device parameters variation
Reflect unobvious, test effect is bad.
This programme is achieved by the following technical measures:
It is a kind of can safe on-line checking in-line arrangement fuse, include shell, safety control circuit component, high pressure detonation group
Part, detonator assembly, electric interfaces and test interface；Safety control circuit component, detonator assembly, electrically connects high pressure detonation component
Mouth and test interface are each attached on shell；Safety control circuit component is electrically connected with electric interfaces and high pressure detonation component respectively
It connects；High pressure detonation component is also electrically connected with detonator assembly；Test interface respectively with safety control circuit component and high pressure detonation group
The interface of the inter-module of part is electrically connected.
As the preferred of this programme: the outside of housing tip is arranged in electric interfaces.
As the preferred of this programme: the outside of housing tip is arranged in test interface.
As the preferred of this programme: enclosure interior is provided with bracket；The safety control circuit component and high pressure detonation group
Part is arranged on bracket.
As the preferred of this programme: the bottom end of detonator assembly setting inside housings.
As the preferred of this programme: the electrical connection carrier between each component is cable.
The beneficial effect of this programme can according to the description of the above program, due to using test interface in this scenario
The component interface for being connected to safety control circuit component and high pressure detonation component powers on connection, fuse system when can satisfy test
System does not work, and can not dismantle detonator and carry out on-line testing；Test interface is connected to component interface, passes through testing impedance detection system
It whether normal unites, is studied through preliminary test, can effectively find most of hardware fault problem；Using independent test interface, do not change
Become the original electric interfaces of fuse, does not increase detection circuit in the product, do not increase product power consumption, cost, volume substantially.
It can be seen that compared with prior art, the present invention having substantive features and progress, the beneficial effect implemented
It is obvious.
