The requirement of security, rocket projectile, shell etc. utilizes the varying environment such as recoil, creeping force and nutating power in-flight letter when launching
The report for ceasing arming is very more.Because of the particularity of bomb trajectory environment, typical fuze environment information incentive such as recoil,
Creeping force, nutating power etc. is to bomb fuze and does not apply to.With Fuze warhead matching technology and draw the integrated development of war, guidance information
Using also turning into a kind of trend, as firing mount separation information that control cabinet collects, target seeker collect target range information, these
Information can be utilized by fuse ESAD, but information content and limited types and transmission means by electric interfaces by recognition result with
Level signal or serial communication mode pass to fuse ESAD, due to the limitation and commonality of electric interfaces so that altogether because
Failure causes the risk increase that abnormal insurance releases.It is existing simply to be confined to glide come arming using missile wing expansion information
Guided bomb.This outer portion bomb increases wind wing generation environment information, and this method destroys body contour structures, and aerodynamics
Performance.Therefore had difficulties using a kind of easily realization, highly reliable bomb environmental information arming.
The content of the invention
The purpose of the present invention, aiming at the deficiency present in prior art, and one kind is provided and is based on mems accelerometer
Aerial guided bomb fuse and its environmental information recognition methods, pass through the MEMS inside certain aerial guided bomb fuse
Whether the downward overload values that accelerometer measures aerial guided bomb fuse under launch environment is born reach G and duration
For T, disembarked to identify whether the bomb is launched, so as to provide environmental information excitation for fuse arming.
This programme is achieved by the following technical measures：
A kind of aerial guided bomb fuse based on mems accelerometer, includes body and fuse, and fuse is fixedly mounted

A kind of Identify Environment of the aerial guided bomb fuse based on mems accelerometer, includes following steps：
A, MEMS and speedometer collection X-axis acceleration and Y-axis acceleration, and calculate the resultant acceleration of X/Y plane；
B, the collection of continuous 5 times, the resultant acceleration being calculated are averaged, often obtains a resultant acceleration average value
All it is compared afterwards with threshold values；
C, repeat step a, b if resultant acceleration average value is more than or equal to threshold values, all compares threshold value in T/1.25 times
It is big or equal, show that bomb has been launched and disembarked, a kind of excitation can be used as to release fuse and insured together；In T/1.25
As long as having smaller than threshold value 1 time in secondary, then show that bomb is not launched, fuse not arming, T is preset durations.
As the preferred of this programme：In step a, MCU gathers the obtained acceleration of an ADC0 and ADC1 every 250us
Value, is designated as G respectivelyxAnd Gy, then respectively by X-axis acceleration GxWith Y-axis acceleration GyIt is squared to obtainWithThen by it
Phase adduction opens radical sign and obtains the resultant acceleration of X/Y plane
The beneficial effect of this programme can be learnt according to the narration to such scheme, be drawn due to using to be arranged in this scenario
The internal accelerometer of letter controls whether fuse releases security control as the foundation for judging bomb and whether launching, and with this；Should
Released in fuse electronic safety and arming device for fuse insurance and a kind of environmental information excitation is provided, had and do not destroy
Body aerodynamic configuration, it is not necessary to extra power electricity transformational structure, be easily engineered, the high advantage of reliability；Apply in fuse electricity
High security can be achieved in sub- fuze safety and arming device device while realizes miniaturization low-cost design.
As can be seen here, the present invention compared with prior art, has substantive distinguishing features and progress, its beneficial effect implemented
It is obvious.
