Description
Technical field
The utility model relates to in-line arrangement fuse, especially it is a kind of can safe on-line checking in-line arrangement fuse.
Background technology
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, in addition to high security, high reliability, Ling Yichong
It is to have good testability to want feature.Tradition machinery fuse or mechanical-electrical fuze, because solution guarantor's process is irreversible, production assembling
After the completion of can not carry out complete solution protect, the test of the workflow such as triggering.In-line arrangement fuse, will be removable before producing and shooting
Unload after Slapper detonator is substituted for simulation detonator sub-assembly, comprehensive test of fuse performance can be achieved.
But after fuse is attached to body, because what is installed on fuse is actual primer, and typically do not possess the mould that changes the outfit
Intend the operating condition of detonator, it is contemplated that security, it is impossible to be powered up test.I.e. various fuses are once attached to body at present
Afterwards, it is impossible to carry 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 ensure that systemic-function is normal, it is ensured that be reliably completed strike task.Fuze system is surveyed online before turning into transmitting
The blind spot of examination.
Shen Bo of Xi'an Electro-mechanical Information Inst. et al. was in the paper delivered in 2010《Increase CAN for electronic time fuze
Bus selftest module》In, propose that one kind can be directed to the measurement of the four class measurement points such as magnitude of voltage, resistance value, time value and switching signal,
The scheme of electronic time fuze functional test is completed when setting by CAN module.The program has certain novelty, but also deposits
In some deficiency：First, because mechanical-electrical fuze solution is protected, process is irreversible, and only inquiry solves guarantor's state, is not to vital safety
System function is tested；2nd, detonator inner walkway could be carried out after transmitting, and practical significance is little；3rd, selftest module adds
The requirement such as system bulk, cost, power consumption, because electronic time fuze security system is not tested, volume, power consumption are reflected in text
Little etc. cost, if tested fuse comprehensively, increased volume, power consumption etc. may be larger.
Utility model content
The purpose of this utility model, aiming at the deficiency present in prior art, and providing one kind can examine safely online
The in-line arrangement fuse of survey, the program is using setting test interface to be connected with the key point of each intraware interface, due to electronics
Impedance can produce change after component failure, and then influence the impedance of the test point of component interface, therefore load guided missile in fuse
Afterwards, missile control system can determine whether most of device by the testing impedance of fuse test interface（Device is not isolated）Shape
Whether state is normal, and then judges fuse state and performance.Why inter-module interface testing point rather than fuse are used to dispatch from foreign news agency
Gas interface testing impedance, it is due to that the external electric interfaces of fuse are typically provided with various isolating devices, internal device parameters is become
The reflection unobvious of change, test are ineffective.
This programme is achieved by the following technical measures：
It is a kind of can safe on-line checking in-line arrangement fuse, include housing, safety control circuit component, high pressure detonation group
Part, detonator assembly, electric interfaces and test interface；Safety control circuit component, high pressure detonation component, detonator assembly, electrically connect
Mouth and test interface are each attached on housing；Safety control circuit component is electrically connected with electric interfaces and high pressure detonation component respectively
Connect；High pressure detonation component also electrically connects with detonator assembly；Test interface respectively with safety control circuit component and high pressure detonation group
The interface electrical connection of the inter-module of part.
As the preferred of this programme：Electric interfaces are arranged on the outside of housing tip.
As the preferred of this programme：Test interface is arranged on the outside of housing tip.
As the preferred of this programme：Enclosure interior is provided with support；The safety control circuit component and high pressure detonation group
Part is arranged on support.
As the preferred of this programme：Detonator assembly is arranged on the bottom of enclosure interior.
As the preferred of this programme：Electrical connection carrier between each component is cable.
The beneficial effect of this programme can be learnt according to the narration to such scheme, due to using test interface in this scenario
It is connected on the component interface of safety control circuit component and high pressure detonation component and electrically connects, fuse system when disclosure satisfy that test
System does not work, and can not dismantle detonator and carry out on-line testing；Test interface is connected to component interface, and system is detected by testing impedance
Whether system is normal, 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, increase does not detect circuit in the product, does not increase product power consumption, cost, volume substantially.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, its beneficial effect implemented
Fruit is also obvious.
