Description

TECHNICAL FIELD [0001] The present invention relates to a measuring apparatus and a measurement method,

The present invention relates to an apparatus for measuring the time of a new bombardment in a defense industry field, particularly in the field of defense weapons, and a method of measuring the bombardment time of the new bombardment. Or the target output signal of the target detection signal or the like, and confirms the ignition timing based on the internal time of the fuse. More specifically, a timer is used to measure the time interval between the start of the flight and the time from the start of the detonation to the start of the detonation, to record the time at which the detonation confirmation line breaks, and to store the main fuse output signal, And a method of measuring the time.

The new building guarantees the safety of the warhead / ammunition until the storage, transportation, handling and launching of the bullet, secures the safety distance at the time of launching the bullet, changes to the loading state capable of igniting, and finally when the target point or target is reached It serves to detonate the warhead at the intended time. The fuse is a very basic and important part in terms of maximizing the safety and effectiveness of weapons as a device that protects the friendly from the unintentional explosion and performs the explosion exactly at the desired time to maximize the damage of the destruction target. Therefore, in order to confirm the performance of such a fuse at the time of development, it is necessary to take a test to confirm the exact firing time point, not merely an aeration.

In the past, there have been various methods of indirectly confirming the discharge of the electronic signal such as the fuse command of the fuse and the charge voltage of the fuse capacitor by using a separate measuring instrument, a method of confirming the final operation of the fuse tube after the recovery, A flame or a glare was generated and the camera was photographed and confirmed. However, there is a limitation in that it is impossible to confirm whether the explosion has actually occurred at a desired point in the method of indirectly confirming with a fuse command or charge voltage and visually confirming whether an explosion tube is operated after an impact, In order to accurately measure the time difference in microseconds, it is necessary to set the frame rate to a high-speed (high-speed) mode in order to accurately measure the time difference in microseconds, It is difficult to construct a test because it is necessary to operate a camera and it is costly and it is difficult to confirm and evaluate only the performance of a fuse itself because it can not know a time difference from a fuse internal viewpoint from a fuse command to a fuse.

The present invention precisely records the time at which disconnection of the confirmation line is occurred by measuring the time interval between the start of flight and the time of detonation of the detonation pipe and the time of detonation and stores the main fuse output signal in a memory located inside or outside the fuse And to provide an apparatus and a measuring method for measuring a firing time of a new fender to grasp the firing characteristics of the fender.

The present invention includes a timer for receiving a flight start signal from a fuze, a memory for recording an event monitoring signal transmitted from the fuze and an ignition confirmation signal, and a confirmation line for cutting when the fuze is detonated, The change point is stored in the timer and the event monitoring signal stored in the memory is compared with the explosion confirmation signal on the basis of the change point, Is calculated.

When the present invention is applied, it is possible to precisely know the time elapsed from the time of the event of the detection of the target or the time of the event of the fuselage signal, and to detect the abnormal point of time The test can be confirmed after the test.

In addition, it is possible to more reliably verify the function of the new building by allowing the user to confirm the degree of delay with which the new building is disengaged by the time of the internal standard of the new building.

5 is a circuit schematic diagram of an explosion confirmation line according to the present invention. As shown in FIG. 5, one side of the confirmation line 100 is connected to the resistor 140. When a current flows when the confirmation line is connected, a potential difference is generated at both ends of the resistor and the confirmation line is disconnected When the potential difference disappears, the above-described confirmation signal changes remarkably, so that this point (the point of time when the confirmation line is cut) is detected as the point of occurrence of the explosion.

The visibility confirmation line 100 may be an FPCB on which a plurality of conductive lines are mounted, and the visibility confirmation line has a certain thickness and width. A plurality of stranded wires are passed through the cut portion 110 so that at least one strand of the stranded wire 410 is cut off so that a change point of the malfunction confirmation signal 502 is generated.

The clearance of the confirmation line is minimized by applying an adhesive to the insertion groove 310, inserting the confirmation line 100, and fastening the body 300 and the lid 200 together.

The lid part 200 may be formed of an insulating material so that the confirmation line 100 is cut by the opening of the new pipe 400 so that the conductive part of the flexible circuit board FPCB contacts the lid part. Thereby preventing signal blurring of the explosion confirmation signal 502. [

The event monitoring signal (12, 422, 454) and the confirmation signal 502 are separately constructed or separated from the power source used in the fuse box 400, It is designed to have a response speed within a second, so that the interval between signals can be measured accurately.

The second storage step S40 receives and stores the event monitoring signal 12, 422, and 454 and the weather confirmation signal 502 stored in the first storage step S20, All the information in the volatile memory 510 is deleted and only the signal data in the nonvolatile memory 520 is used in the calculation step S50.

FIG. 2 is a view showing an event monitoring signal and an explosion confirmation signal of a before-after time (non-active memory storage area) based on an explosion occurrence time point.

2, and 6, the signal processing unit in the new pipe 400 senses the start signal 20 and then transmits the start signal 22 to the fuzzy alarm time And transmits the event monitoring signals 12, 422 and 454 and the confirmation signal 502 to the volatile memory 510 in step S20. Thereafter, when the detonation confirmation line 100 is disconnected due to the detonation of the new pipe 400, and the change in the detonation confirmation signal 502 occurs, the detonating device 500 detects it, The value of the timer 530 at the time when the change in the explosion confirmation signal 454 occurs (the time at which the explosion occurs) is stored (S30). The event monitoring signal 12, 422, and 454, the explosion confirmation signal 502, and the detonation point timer 530 in the interval t2 (t2) Volatile memory 520 from the volatile memory 510 through the nonvolatile memory 510 in step S40 and the event monitoring signal 12, 422, 454 stored in the nonvolatile memory after the test and the acknowledgment signal 502 (S50), the time difference between the start point of the flight and the start point of the attack is calculated.
