Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a shock-absorbing method for detonating a shock-

The present invention relates to a shock detection technology of an electronic part circuit disappearing type for effectively coping with various impact situations which are difficult to be detonated by only an impact sensor in a multifunctional electronic crimp pipe which is difficult to mount a shock detection structure.

Impact fuse refers to a fuse that is detected by a shock sensor or an impact detection structure located inside a fuse when a shell collides with a target, and is output by outputting an impulse signal.

A shock sensor, also called a shock switch, is normally operable by retraction inertia or spin applied to the cannon after the cannon is deployed. After that, when the target collides, the electrical contact is generated due to the sudden behavior or destructive deformation of the inertial weight built in the sensor And outputs an impact detection signal.

Inertia generators that generate contacts usually have pure mechanical structures that utilize the behavior or deformation of internal components, such as ball or pendulum, but rarely designs using piezoelectric elements.

On the other hand, the impact detection structure is a method of detecting an impact due to collapse or breakage of a specific site of a structure intentionally designed and disposed in front of a new pipe in a target collision.

The impact sensing structure, which directly utilizes the collapse of the structure, is called a crush switch. Since the electric contact state is maintained as it is, the vibration of the internal inertia weight can compensate the shortcoming of the shock sensor having a short electrical contact time.

However, since the collapsing structure occupies most of the inner space of the nosecone, it is difficult to arrange the other parts such as the antenna and the control circuit inside the nosecone of the new pipe.

The following document (1) shows a new fuse with a typical impact switch, and (2) shows a classic fuse with a typical shock detection structure. These are pure impact cymbals which are difficult to be equipped with antennas for proximity sensors, timed explosion timers, and other control circuits since they occupy most of the space in the front of the new building due to the construction space of the shock detection pendulum or collapsing collapse after impact.

On the other hand, recent fuses are gradually becoming highly integrated and multifunctional, thanks to the advanced electronic technology. The proximity sensor radar antenna, which occupied most of the internal space of the Nosecon, has been reduced to less than half the size of the earlier antenna due to the retrofit of the used frequency, that is, the microwave oven. Using a high performance input / output control processor (MCU) It is able to handle various functions such as explosion altitude detection, flight distance measurement and electronic timer operation for time explosion as well as FMCW signal processing for radar.

The latest MCUs for control of new buildings are made of ultra-small, light-weight chips with excellent shock resistance and power consumption, as well as printed circuit boards (PCBs) And can be easily mounted (mounted) at desired positions and numbers.

In spite of the harsh operating environment unique to the bombardment, such as high-speed spin for bombardment shock and ballistic stability, the latest shell cannons are free-fall induction type They show almost equivalent processing power and reliability compared to control circuits mounted on bombs or air-launched missiles.

As for the functional arrangement structure of the new building, functions normally terminated before the impact of the shell (before destroying the nose portion) such as proximity sensor, magnetic sensor, and flight time timer do not need to be protected from collision impact, And is assigned to the electronic sub control circuit disposed in the rear space. And the functions that need to survive after the impact impact, such as the impact sensor and the delayed detonation circuit for explosion after the target collision (after target penetration), are assigned to the detonator control circuit located in the lower main housing rather than the inside of the noscon It is common.

(1) US registered patent US 3994230 Self-destruction type nose impact fuze for spinning projectiles (2) US registered patent US 4382408 Circuit arrangement for an impact fuze (3) Korean Patent No. 0145209 Multifunctional fuse system, function selection and operation method (4) Korean Patent No. 1430581 A shock sensing device using a flexible circuit board and an insulating sheet

The latest electronic bombardment that can electronically input and process various control functions such as close-up explosion, set altitude / distance explosion, and time explosion can be basically equipped as the last detonation device (Refer to document (3)).

However, as described above, there is no room in the nose space as described above, so that it is impossible to install the shock detection structure using collapse or break of the frame contact. There are two small impact sensors (mechanical impact switches) installed in the detonation circuit It was all of the shock detection function.

In general, the reliability of impact detection depends on the application position of the impact sensor, the input angle, and the number of mountings. The impact sensor of the multifunctional electronic fuse tube described above has a disadvantage of the short switching time described above, Unless a typical angle of incidence is detected, the detection could fail.

In view of the tendency of recent shells to adopt the delayed explosion method that explodes after an air explosion or glove penetration that maximizes debris effects, if the enemy uses low strength protective materials such as wood or earth wall as glove material With one or two impact sensors, it is difficult to ensure a definite attack at the time of landing.

Especially, the conventional shock sensor described above is not likely to work until a target or plywood made of a thin metal plate such as an ordinary commercial vehicle or an airplane fuselage is stacked over a plurality of pieces of disturbed target and passes through it.

Likewise, when the area is subjugated, when the failed shell fails to fall on a loose ground, such as a snowy area or a swamp, or falls on a feature with reduced spin (shock switch is disabled) such as a bush or bush, There is a disadvantage in that the missile can not be successfully operated and the dangerous misfire state of unrecovered shells can be continued.

In order to solve the above-mentioned weaknesses, apart from the impact sensor, attempts have been made to utilize the breakage and breakage of the FPCB as an additional shock detection structure.

Referring to the document (4) filed by the Agency for Defense Development in 2014, a flexible PCB for a lead frame shrink tube which combines a seat cable in which a current is generated at a predetermined impact or more and a crush switch for outputting an ignition signal at power- I do not know. Referring to Document (4), a sheet-like cable to be cut at the time of impact is designed so that the cut-off layer is filled with a polycarbonate containing 40% of glass or is easily broken into an empty space. This paper also briefly introduces the concept of simplification and reliability improvement of PCB switch design that outputs an impact signal to an explosion circuit when cable cutting condition occurs.

However, in document (4), there is no description as to which part of the new pipe is broken and how the sheet cable attached to the new pipe-specific part is broken by the breakage when the target of the projectile is struck, No specific details on how to work with impact sensors to improve overall shock detection capabilities are available.

Accordingly, it is an object of the present invention to provide a new and compact shock detection structure that overcomes individual technical limitations of the above-described prior art documents and entirely embodies sensing principle and sensing step.

The present invention relates to a low permittivity material for transmitting a radar wave, wherein most of the electronically controlled fuse assemblies equipped with a plastic nosecone are shattered by almost all of the nosecone nose portion including the nosecone and the electron portion inside thereof during a target collision, ).

Referring to the simulation image of the shot target penetration through the shell of FIG. 1, almost all of the nose portion including the plastic nose portion is broken in the collision with the wooden guard, not the steel glove. If the wood protection is a laminate of several layers or a low strength synthetic wood mixed with sawdust, the amount of deceleration applied to the shell during penetration can be very small, and at such low acceleration the impact sensor located in the detonator housing will not work . This means that if the target you want is a wooden house or an aircraft that has been placed on the ground, it can not be effectively destroyed.

FIG. 2 is a more detailed simulation model of the post-penetration crash condition of FIG. If you look closely at the new pipe which has almost completely disappeared from the nose area when it collides with the plywood of about 20cm in thickness, the disk-like structure (the half-disk-shaped structure due to the incision image) attached to the upper surface of the main body (main housing) can see. If the disk-like structure is almost completely consumed and the remaining electronic control circuit board and the electronic bottom PCB 14 to be described below are used, the circuit can be advantageously utilized to output a useful signal.

The most important characteristic of the present invention is that the shunt 12-1 is added to the PCB of the part of the electronic fuse that is completely lost during the target collision, And the electric conduction state, that is, the normally energized state, is maintained by flowing a current to the shunt from the time when power is applied to the new tube to the timing of the collision, and then the corresponding PCB When the energized state is canceled by the disappearance of the signal, it is converted into a meaningful signal.

Here, the shunt 12-1 is merely an energizable electric wire, not a branched circuit that performs any specific intelligent operation. In other words, a PCB which performs a specific function such as an induction field is mounted on the PCB (the lower part of the PCB 12 is referred to as the upper part of the PCB in the following description). However, (Shunt) 12-1 through which the current always flows only on the basis of means capable of recognizing the energized state and the uninterrupted state (circuit breaking state).

When the shell collides with the target and the nosecone of the new pipe and the electronic part therein are broken, the shunt 12-1 is cut off from the energized state, and the electronic part MCU 14-1 (micom) And outputs an awake signal. At this time, as shown in FIG. 2, the electronic MCU 14-1 is disposed at the bottom of the disk-shaped structure, that is, inside the nosecone, and remains on the upper surface of the main housing after the disappearance of the nose portion. The MCU may be an MCU mounted on the PCB (14).

The detailed structure and impact detection algorithm specifically supporting the above contents refer to the detailed description below.

According to the present invention, the impact detection / shock delay detection function that complements the performance of the impact sensor built in the electronic fuse can be implemented very effectively without reducing the layout space of the peripheral device or loss of function.

The present invention has no restriction on the switching holding time of the impact detection signal, so that the sensitivity setting of the impact detection process is free and the reliability of the entire system can be improved.

In addition, since the present invention is to add the pattern effectively to the portion that does not affect the original function of the apparatus at all, such as the outermost portion of the substrate, in consideration of the supporting structure of the PCB inside the new pipe, It does not cost. Therefore, it is possible to completely eliminate the impact sensor built in the ignition part or to shut off the function according to the use of the new pipe and the characteristics of the target, as well as the utilization of the internal space.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will be more apparent from the following description taken in conjunction with the accompanying drawings, in which: FIG.

However, in the embodiments described below, the components expressed in the specific terminology and the combination structure thereof do not limit the technical ideas encompassed in the present invention.

FIG. 3 is a partially cut-away view of the surface of the electronic fuse tube to which the present invention is applied. The main body of the new pipe is formed with a main housing 30 having a thick section and a sub-housing 20 having a relatively thin thickness coupled to the main housing.

The inner space of the main housing 30 is allocated as a detonator. In the present invention, the detonator is used as a space in which the detonation-related component is mounted, that is, in the sense of some compartment, and thus is not defined by reference numerals. The main components of the detonator are assemblies (assemblies) consisting of a battery 31 and detonator PCBs 32 and 34 on which an explosion circuit is printed. Underneath the detonator assembly, an explosion pipe 40 and an explosion charge 42 are disposed, and a safety loading device (not shown) is provided between the explosion pipe 40 of the new pipe and the explosion charge 42 41 are disposed. When the safety loading device (41) is normally unlocked, the violent force of the explosion tube is transmitted to the interior of the shell along the central explosive path filled with explosives.

Usually, the detonator assembly is designed to have a very tight sealing structure by using a high-strength material having a sufficient thickness, since the life of the detonator assembly must be guaranteed at a certain point after the target penetration. That is, the main housing 30 has a strong protection structure that can withstand the maximum penetration force of the shell. When the main housing 30 is mounted on most soft targets such as a thin metal plate or wood, the sub housing 20, which is thinner than the main housing, Even some of them can survive.

Although not shown in FIG. 2, the results of the experiment in which a part of the lower edge of the sub housing and some of the structure of the upper part of the main housing are not completely lost in the soft target penetration test such as plywood.

On the other hand, the nose cone 10 is assembled to the upper side of the upper sub housing 20.

The internal space of the nosecone 10 is allocated to the electronic part. (The electronic part is used in the sense of the present invention in the sense of the present invention and is not defined by the reference numerals.) The major components of the electronic part are the antenna 10- 1), an induction field input coil 11 for charging a mission to a new pipe using electromagnetic induction phenomenon (data input), and electronic part PCBs 12 to 14 laminated with a multi-layer disc-shaped circuit board thereunder ≪ / RTI > The electronic subassembly performs various operations such as detecting the distance to the target, the relative altitude, etc., and calculating the flight time during the flight of the shell, and transmits the result to the above exploit.

For reference, a filling material for protecting the antenna 10-1 from the impact of the foil blowing can be filled in the inner space of the nosecone 10.

The nosecone and the filler in the nosecone have a low permittivity material capable of transmitting the signal of the frequency band of use, having density and hardness capable of fixing the antenna and the related structure due to the characteristic of the new pipe to transmit the RF signal of the proximity sensor, A material having a relative dielectric constant of about 1.2 to 4.7 can be adopted. Thermosetting plastics and foamable plastics are mainly used because they have a permittivity that matches them. They are hard enough to be shattered with the inner electron assembly, regardless of the angle of impact when landing the target, but are comparable to the main housing and subhousing So it is possible to detect a more various (soft) impact impact situation.

An electronic part and an ignition part to which the technical idea of the present invention is applied will be described in detail with reference to Figs. 3 to 6 as a whole.

For reference, the electronic part and the detonator defined in the present invention are any partitions, that is, the entire space for performing a functional operation. The term " electronic part " The detailed layout and structure can be understood as an installation and operation space that can be changed according to the flexibility of the designer.

FIG. 4A illustrates an electronic subassembly disposed within the nosecone 10, and FIG. 4B illustrates a top PCB and a bottom PCB joint structure in the electronic subassembly.

The electronic part includes stacked PCBs 12 to 14 that perform the overall sensing signal processing function of the new pipe.

4A shows that the stacked PCB is three layers. The upper, middle and lower PCBs 12 to 14 are tightly coupled to the electronic part supporting structure 15 and the electronic part PCB fixing pin 15-1 so as not to be damaged from the impact shock.

FIG. 4B shows an intermediate layer, i.e., the electronic part stop PCB 13, which is not related to the operation of the present invention. The middle layer PCBs can be stacked with 0 to 3 layers depending on the sensor function, the signal processing speed and the information processing capacity of the new tube.

The shunt PCB 12 of the upper layer is provided with a shunt 12-1 which is supplied with power through an electronic part cable 16 electrically connecting the electronic part lower end PCB 14 and the electronic part upper PCB 12, Is formed in the form of a circular closed loop along the outermost edge of the electronic floating terminal PCB 12. [ In addition, the electronic part MCU 14-1 is mounted (circuit-mounted) on the electronic part lower PCB 14 of the lower layer.

Preferably, the electronic floating terminal PCB 12 may be an induction field input related circuit board whose mission is completed before the shell is fired so as not to affect the operation of the electronic part MCU 14-1 in the lower layer even if it is lost first.

Preferably, the electronic unit MCU 14-1 processes a time-lapse explosion signal by a radar signal for a proximity sensor or a timer, and transmits the altitude or flight time to the igniter MCU 34-1 as the ignition data Signal processing processor.

In other words, a function of outputting a disconnection signal or a disconnection data according to a disconnection is added to the function of original signal processing (disconnection data generation) by sensing the disconnection of the shunt 12-1.

The shunt 12-1 may be formed along the outermost edge of the upper PCB and may be patterned so as to include a coupling hole of the PCB fixing pin 15-1. In this design, the electronic part PCB fixing pin 15-1 is buckled immediately by the impact of the shell, and the shunt 12-1 is firstly shut off (shut off) before the entire electronic part disappears. .

The detailed design of the electronic MCU or shunt as described above means that the function of the present invention can be added without giving any functional or spatial loss to the conventional electronic fuse.

FIG. 5A shows an exploder assembly mounted inside the main housing, and FIG. 5B shows a combined structure of an upper PCB and a lower PCB in the explorer assembly. FIG. 6 selectively illustrates only the portions that perform the core function of the present invention in FIGS.

Referring to FIG. 3, the main housing 30 is located below the electronic part because the main housing is coupled under the nosecone 10.

The detonator is disposed inside the main housing 30 and includes a battery 31 and an igniter MCU 34-1 as core components and an igniter bottom PCB 34 on which an igniter MCU can be mounted, And an impact sensor 34-2 for sensing an impact applied to the main housing 30 when the user catches the impact.

The detonator cable 36 electrically connects the detour lower PCB 34 and the lower electronic PCB 14 to each other.

When the shell is fired, power is supplied from the battery 31 through the detonating cable 36 to the circuit of the lower electronic part PCB 14 and again through the electronic part cable 16 to the circuit of the electronic floating terminal PCB 12 Supply power.

That is, when the shell is fired, the battery 31 supplies power to the entire PCB through the above-described ignition part cable 36 and the electronic part cable 16, and particularly to the shunt 12-1 formed at the top part of the electronic part, And is maintained in the normally energized state.

FIG. 7 is a comprehensive explanatory view of the method of exploiting the invention of the present invention based on the technical idea of the present invention.

As a first step, when power is supplied to the new pipe after the shell is fired, one of the immediate explosion due to the impact impact and the delayed explosion due to the impact impact is selected,

In the second step, shut off due to disappearance of the shunt 12-1 formed in the electronic part and simultaneous occurrence of the shock contact of the impact sensor 34-2 built in the detonator are detected do.

Thereafter, a third step of outputting an ignition signal is performed when any one condition is satisfied by parallel signal processing of the generation of the short circuit and the shock contact,

In the first step, a fourth step of immediately outputting an ignition signal (ignition energy) when the explosion is selected immediately and outputting an ignition signal (ignition energy) after a predetermined time delay when the delayed explosion is selected may be performed.

The key functions of the present invention will be described in detail on the basis of the above-mentioned basic layout structure and the comprehensive exploitation method.

When the power is supplied to the dual MCUs 14-1 and 34-1 after the shell is fired, the energization state of the shunt 12-1 and the switch state of the impact sensor 34-2 are checked, and the state of the shock sensing standby state is obtained.

When the shunt 12-1 is shut down due to the collision of the shell with the electronic lifting PCB 12 disappeared, the electronic MCU 14-1 senses the shunt and the MCU 34-1 It is possible to output a short duration ignition signal irrespective of the operation of the motor.

The electronic part MCU 14-1 can be supplied with power through the ignition cable 36 regardless of whether the electronic part cable 16 is energized or not, When the shunt 12-1 is cut off, it senses it and transmits it as disarmed data to the disarming MCU 34-1. The disarming MCU 34-1 receives the transmitted disarmed data and outputs the disarmed aircraft signal It is possible.

That is, in this case, it is not desired to give the electronic part MCU the output function of the detonation signal in order to reduce any design problem or possibility of error.

Both of these modes of operation mean that the electronic MCU (34-1) is alive for a few minutes (~ several tens of nanoseconds) after the impact of the shell and has been hit by very soft objects (such as swamps or plywood or airplanes) .

On the other hand, when the electronic floating terminal PCB 12 disappears due to the collision of the shell, the evacuation unit MCU 34-1 directly detects the shut state of the shunt 12-1 and outputs a short arm ignition signal It is possible.

The above operation mode is the case where the electronic part MCU 34-1 can not guarantee the survival of the MCU 34-1 immediately after the collision, and the shunt sensor is not operated, that is, it is hit by a moderately loose object (logs, brick walls, etc.) .

Of course, the detonating MCU 34-1 can detect an impulse contact generating signal of the impact sensor 34-2, irrespective of whether the electronic unit MCU 14-1 outputs a single ignition signal or an ignition data, And outputs a shock detonating signal. This is the inherent impact detection capability, that is, when you hit a ground, rock, or enemy target. According to the mission design, the disarming MCU 34-1 immediately outputs an alarm signal when an impact signal is input, and outputs a delayed alarm signal after a predetermined time after the impact signal is input if the alarm signal is a delay fuse.

According to the detailed design diagram, the detonating part MCU 34-1 is set to delay or immediately output only one of the short-circuit detonation signal and the impact detonation signal in response to a command input before the shell is fired. In other words, an explosion signal can be output based on the shock signal detected first of both the nose shunt and the explosion shock sensor, or the priority can be set as needed. This can be entered into the executable code by the user before the launch.

Since the switching time of the impact sensor 34-2 is slower than the downtime detection time of the shunt 12-1, it is input to ignore or delay output the unit ignition signal when the explosion is desperate for the mission target after passing through the glove target . Even when the glove target deviates from the target, the delayed dysfunctional signal can eventually be output, so there is no nuisance that is difficult to remove.

As a result, the present invention has an advantage in that even if one MCU malfunctions or breaks down, the function can be performed because both of the micro-control unit (MCU) of the electronic part and the wake-up part are provided with the ignition function to implement the dual- .
