Embodiments of the present invention relate to a nuclear explosion alarm and a method for implementing the nuclear explosion through the omnidirectional gamma radiation detector capable of predicting the direction of nuclear explosion using a gamma radiation detection sensor and a high-speed detection function.

When a nuclear explosion occurs, materials located within a few Km radius from the nuclear explosion evaporate, and strong energy generated by the nuclear explosion is propagated up to several hundreds to thousands of kilometers away, causing malfunctions and inoperable states of various electronic devices.

This effect paralyzes communication and power systems in case of emergency and significantly lowers the operational control capability of the military. Therefore, it is essential to develop technology to minimize the effects of nuclear explosion.

Detection sensors with high speed detection and protecting the equipment by cutting off the main power applied to the main parts of electrical and electronic equipment based on the detected signal are commercially available.

However, due to the directionality of the detection sensor, normal operation can be guaranteed when the sensor is incident perpendicularly to the sensor plane.However, when gamma radiation enters the detection sensor horizontally or at an angle, the ionization current output from the detection sensor decreases, resulting in a nuclear explosion. There is a case where it is not detected.

In addition, even if detected, there is a problem that can not accurately grasp the information on the direction of the nuclear explosion in the current position.

Thus, if each entity (airplane, tank, destroyer, etc.) located within the sphere of impact of the nuclear explosion cannot gather information from outside for a certain period of time, it is important to survive the nuclear impact if it can detect the direction of the nuclear explosion itself. It is expected to be used as information.

1 is a conceptual diagram illustrating the overall functional role of a nuclear bomb generator according to an embodiment of the present invention.

When a nuclear explosion occurs, strong nuclear energy, such as gamma radiation, neutron radiation, thermal energy, and nuclear storms, may be transmitted at high speed to a point corresponding to hundreds to thousands of kilometers from the nuclear explosion center 110.

Referring to FIG. 1, the area in which nuclear energy delivered by a nuclear explosion is delivered is an absolute danger radius 120 in which all electronic devices are damaged by nuclear energy despite any action, and the electronic device is protected from nuclear energy through appropriate measures. The risk radius 130 may be divided into.

When the nuclear bomb detector detects gamma radiation caused by a nuclear explosion above a threshold level, a NA signal is generated to operate a crowbar circuit to cut off power to major circuit parts to protect an electronic device. can do.

Accordingly, in the case of the warship 150, the tank 160, or the aircraft 170 located in the danger radius 130, it is possible to detect an approximate direction of the nuclear explosion, and position the nuclear explosion to the outside through available communication equipment. The danger radius 130 can be avoided by discharging and turning the heading direction of the nose in a direction opposite to the nuclear explosion.

In contrast, in the case of the armored vehicle 140 located at the absolute danger radius 120, all the electronic devices provided may be damaged and become inoperable despite any measures.

2 is a view showing the configuration of a nuclear alarm according to an embodiment of the present invention.

The nuclear warning device 200 according to an embodiment of the present invention includes a radiation detector 210, a sensing information generator 220, a direction predictor 230, a memory 240, and a signal generator including a plurality of detection sensors. The unit 250, the condenser 260, and the threshold level adjusting unit 270 may be configured to be included.

The plurality of detection sensors may be disposed in each of the planes in the three-dimensional space to detect gamma radiation, and output current pulses according to the detection of the gamma radiation.

Each of the detection sensors may detect gamma radiation incident on the YZ plane, the XZ plane, and the XY plane constituting the three-dimensional space, and generate a current pulse (or current amount) corresponding to the detected gamma radiation.

Here, each detection sensor may be implemented as a photo diode for detecting gamma radiation, as in the X, Y, and Z direction detection sensors 510 of FIG. 5.

Hereinafter, the radiation detector 210 will be described with reference to FIG. 3.

FIG. 3 is a diagram illustrating a three-dimensional configuration of each detection sensor for detecting gamma radiation in a nuclear warning device according to an embodiment of the present invention.

Referring to FIG. 3, the radiation detector 210 includes a photodiode 310 for detecting X-direction Gamma disposed on the YZ plane, a photodiode 320 for detecting Y-direction Gamma disposed on the XZ plane, and a Z disposed on the XY plane. Photo Diode 330 for Direction Gamma Detection, Photo Diode Output for S-direction Gamma Detection (s_x_Out) 311, Photo Diode Output for Y-direction Gamma Detection (s_y_Out) 321, Photo Diode Output for Z-direction Gamma Detection (s_z_Out) ), And a photo diode ground (s_com) 340 for detecting Gamma in each direction.

In the Gamma detection photo diodes 310, 320, and 330, a large amount of ionization current is generated when gamma radiation is vertically incident on the YZ plane, the XZ plane, and the XY plane. When incident, the ionization current amount is significantly reduced.

Accordingly, the radiation detector 210 arranges the Gamma detection photo diode 310 on the YZ plane for the X direction detection and the Gamma detection photo diode 320 for the Y direction detection as shown in FIG. 3. Gamma detection photodiode 330 is disposed on the XY plane for Z direction detection, and gamma radiation detection in all directions can be enabled.

Further, the photodiode output (s_x_Out) 311 for detecting the X direction gamma, the photodiode output (s_y_Out) 321 for detecting the Y direction Gamma, and the photodiode output (s_z_Out) 331 for detecting the Z direction Gamma are subjected to gamma radiation. This refers to the output terminal of the ionization current output from each Gamma detection photo diode (310, 320, 330), it can display the current output terminal in each of the X, Y, Z direction.

In addition, each direction gamma detection photo diode ground (s_com) 340 may refer to a terminal in which an anode of the gamma detection photo diodes 310, 320, and 330 disposed in each direction is commonly configured.

That is, the radiation detector 210 configures a detection sensor for detecting gamma radiation generated in a nuclear explosion in a geometric three-dimensional structure, thereby enabling detection of gamma radiation in all directions.

The detection information generator 220 identifies a current pulse output from the detection sensor according to the detection of the gamma radiation, checks whether the identified current pulse is equal to or greater than a threshold level, and includes the detection result to detect the detection. It is used to generate sensing information about the sensor.

At this time, the threshold level adjusting unit 270 is composed of a resistor (R) and a capacitor (C) connected in parallel with each detection sensor, it is possible to adjust the threshold level for the current pulse for each detection sensor.

For example, the sensing information generation unit 220 may generate the sensing information for the detection sensor as a high level when checking the current pulse output from the detection sensor to the threshold level or higher.

In addition, when detecting the current pulse output from the detection sensor below the threshold level, the sensing information generation unit 220 may generate the sensing information for the detection sensor as a low level.

Accordingly, the detection information generation unit 220 includes a detection sensor for detecting the X direction disposed in the YZ plane, a detection sensor for detecting the Y direction disposed in the XZ plane, and a detection sensor for detecting the Z direction disposed in the XY plane. As shown in FIG. 4, the sensed information for each can be generated in eight cases 410 to 480.

In addition, the detection information generator 220 detects each of the X, Y, and Z directions when the current pulse corresponding to the size of the gamma radiation detected by each gamma radiation detection sensor having a three-dimensional geometry is greater than or equal to a predetermined threshold level. Sensing information about the sensor may be generated at a high level or a low level and stored in the memory unit 240.

The sensing information generation unit 220 and the memory unit 240 may be implemented by the analog latch 550 of FIG. 5.

In addition, when the signal generator 250 checks at least one current pulse among the current pulses generated by each detection sensor at a threshold level or higher, the signal generator 250 may be configured to drive a crowbar circuit 280 to cut off power. A first control signal (eg, a Nuclear Alarm signal, NA signal) may be generated to prevent thermal damage of the electric and electronic devices due to the nuclear explosion.

In addition, as the set delay time elapses from the generation of the first control signal, the signal generator 250 supplies a second control signal (eg, an NEF signal) for stopping driving of the crowbar circuit 280. Can be generated.

In addition, the signal generator 250 may generate a reset signal together with the NEF signal to normalize the system.

In this case, the condenser unit 260 may function to set a delay time for generating the second control signal from the time when the first control signal is generated. For example, the capacitor 260 may set a time constant value expressed by the product of the resistor R and the capacitor C as the delay time.

The signal generator 250 may be implemented as the sensor signal amplifier 520, the analog OR gate 530, the pulse delay and the reset signal generator 540 of FIG. 5. In addition, the condenser 260 may be implemented by the condenser 570 for adjusting the pulse delay time of FIG. 5.

The direction predictor 230 predicts a direction in which the gamma radiation is input based on the generated sensing information.

For example, the direction predictor 230 stops the operation of the crowbar circuit 280 after the set delay time elapses and the power is applied to the main circuit. By detecting the direction in which gamma radiation is immediately input using the sensing information of the detection sensor, it is easy to predict the direction in which the nuclear explosion occurred.

The direction predicting unit 230 may select sensing information regarding detection sensors associated with planes which are in contact with each other while maintaining selected angles as sensing information based on prediction of the direction.

Hereinafter, the direction predictor 230 will be described with reference to FIG. 4.

4 is a table illustrating an example of predicting a direction in which gamma radiation is input using sensing information of each detection sensor.

The memory unit 240 includes eight detection sensors for detecting the X-direction, detection sensors for detecting the Y-direction disposed on the XZ plane, and detection sensors for detecting the Z-direction disposed on the XY plane, as shown in FIG. 4. Sensing information of the cases 410 to 480 may be stored.

For example, the direction predicting unit 230 generates sensing information about a detection sensor disposed in a first plane in the three-dimensional space as a high level, and applies the detection information to each detection sensor disposed in planes in contact with the first plane. When the sensing information is generated as the low level, the direction in which the gamma radiation is input may be predicted in a direction perpendicular to the first plane.

As in the case 420 illustrated in FIG. 4, the direction predicting unit 230 has high level of sensing information on the X-direction detection sensor disposed in the YZ plane, and the Y-direction, Z disposed in the XZ plane and the XY plane. When the sensing information of the direction detecting sensor is at a low level, the direction in which the gamma radiation is input may be predicted in the X-axis direction.

Alternatively, as in the case 450 illustrated in FIG. 4, the direction predicting unit 230 has high level of sensing information on a detection sensor disposed in the XZ plane, and the X direction and the Z direction disposed in the YZ plane and the XY plane. When the sensing information of the direction detection sensor is at a low level, the direction in which the gamma radiation is input may be predicted in the Y-axis direction.

Alternatively, as in the case 460 illustrated in FIG. 4, the direction predicting unit 230 has high level of sensing information on the Z direction detection sensor disposed in the XY plane, and the Y direction disposed in the XZ plane and the YZ plane. When the sensing information of the X-direction detection sensor is at a low level, the direction in which the gamma radiation is input may be predicted in the Z-axis direction.

In another example, the direction predictor 230 may generate, as a high level, sensing information about each detection sensor disposed in a first plane in the three-dimensional space and an arbitrary plane in contact with the first plane. When sensing information for a detection sensor disposed in contact with a plane but located in a second plane different from the plane is generated as a low level, the direction in which the gamma radiation is input is intermediate between the axes constituting the second plane. You can predict in the direction.

As in the case 430 illustrated in FIG. 4, the direction predicting unit 230 has high-level sensing information on the X-direction and Y-direction detection sensors disposed on the YZ plane and the XZ plane, and is disposed on the XY plane. When the sensing information of the direction detection sensor is at a low level, the direction in which the gamma radiation is input may be predicted as an intermediate direction between the X axis and the Y axis.

Alternatively, as in the case 440 shown in FIG. 4, the direction predicting unit 230 has high-level sensing information on the Z-direction and Y-direction detection sensors disposed on the XY plane and the XZ plane, and is disposed on the YZ plane. When the sensing information of the detected X-direction detection sensor is at a low level, the direction in which the gamma radiation is input may be predicted as an intermediate direction between the Y-axis and the Z-axis.

Alternatively, as in the case 470 illustrated in FIG. 4, the direction predicting unit 230 includes sensing information about Z-direction and X-direction detection sensors disposed on the XY plane and the YZ plane at a high level and the XZ plane. When the sensing information of the Y-direction detection sensor is at a low level, the direction in which the gamma radiation is input may be predicted as an intermediate direction between the X-axis and the Z-axis.

As another example, when the sensing information for the plurality of detection sensors is all generated as the low level or all the high level, the direction predicting unit 230 may notify the direction detection failure.

As in the case 410 shown in FIG. 4, when the sensing information for each of the detection sensors is all at a high level (that is, when each of the current pulses are all identified above a threshold level), the nuclear explosion may occur at an adjacent distance. It can inform the direction detection failure due to.

Alternatively, as in the case 480 illustrated in FIG. 4, when the sensing information of each detection sensor is all at a low level (that is, when each of the current pulses is determined to be below a threshold level), the direction predictor 230 may notify a normal state in which gamma radiation is detected below a reference value in all directions.

Therefore, according to an embodiment of the present invention, based on the detection information of each gamma radiation detection sensor having a three-dimensional geometry, by detecting the direction in which the gamma radiation is input, it is possible to easily predict the direction in which the nuclear explosion occurred do.

In addition, according to an embodiment of the present invention, the detection sensor for detecting the gamma radiation generated during the nuclear explosion has a geometric three-dimensional structure to enable gamma radiation detection in all directions.

In addition, according to one embodiment of the present invention, by generating a NA (Nuclear Alarm) signal for driving a Crowbar circuit (Crowbar circuit) to temporarily cut off the power to the main circuit, the heat of the electrical and electronic devices due to nuclear explosion Damage can be prevented.

In addition, according to an embodiment of the present invention, by predicting the direction of the nuclear explosion, the electrical and electronic devices operating at any time acts as a protection against gamma radiation, minimizing the impact of the nuclear You can prepare.

In addition, according to an embodiment of the present invention, the electronic device (aircraft, armored vehicle, etc.) by using the information on the direction of the predicted radiation, or guides by transmitting information on the direction of the predicted gamma radiation to an external electronic device The advancing direction of can be controlled.

5 is a diagram showing the detailed configuration of the nuclear warning device according to an embodiment of the present invention.

Nuclear amplitude alarm 500 according to an embodiment of the present invention is X, Y, Z direction detection sensor 510, sensor signal amplifier 520, analog OR Gate 530, Pulse Delay and Reset signal generator 540, Analog Latch (550), Built in Test (560), and may be configured to include a capacitor (570) for adjusting the pulse delay time.

The X, Y, and Z direction detection sensors 510 indicate sensors for detecting the X, Y, and Z direction gamma radiation, and are reverse biased through the photo diode reverse bias voltage input terminal 504 terminal. When a voltage is applied and gamma radiation is input, the X, Y, and Z direction detection sensors 510 may output an ionization current corresponding to the magnitude of the detected gamma radiation and input the sensor signal amplifier 520.

At this time, the X, Y, Z direction detection sensor 510 may input the ionization current to the sensor signal amplifier 520 only when gamma radiation above a threshold level is input.

The threshold level of each detection sensor 510 is Z direction detection sensor threshold level adjustment terminal 501 corresponding to each detection sensor 510, Y direction detection sensor threshold level adjustment terminal 502, X direction detection sensor threshold level adjustment. Terminal 503 can be determined using R (resistance), C (capacitor) connected in parallel to the terminal.

The sensor signal amplifier 520 receives a driving voltage through a VCC (power supply) 505 terminal, and a voltage signal that the analog OR gate 530 can recognize a current pulse input from each detection sensor 510. Can act as a rectifier.

In this case, the sensor signal amplifier 520 may include amplifiers connected to the three detection sensors 510, respectively.

The analog OR gate 530 is regarded as a nuclear explosion when a gamma radiation of more than a reference level is detected by one of the three detection sensors 510 pointing in all directions, and the crow to protect the main circuit portion. It is possible to generate an NA signal for operating the bar circuit.

That is, the analog OR gate 530 monitors the amplifiers connected to each detection sensor 510, and when gamma radiation above the reference level is detected, the NA signal output terminal 506 is connected to the NA signal output terminal 506 to cut off power to the main circuit. The signal may be output, and after the set delay time elapses, the NA signal may also be output to the pulse delay and reset signal generator 540 for power supply and system reset signal generation.

Gamma radiation generated by nuclear explosion affects electronic equipment after approximately 7us after nuclear explosion, and analog OR gate 530 immediately reacts to generate NA signal within several ns or less to drive the crowbar circuit. Therefore, the protection of radiation is performed by cutting off the power to the main circuit part.

Since the pulse delay and reset signal generator 540 lasts for several tens of hours after the gamma radiation is generated, the NEF signal is output high to the NEF signal output terminal 507 after a predetermined time (approximately 100 us) after the NA signal is generated. can do.

In addition, the pulse delay and reset signal generator 540 may normalize the system by generating a reset signal to the reset signal output terminal 508 after a delay time set from the generation of the NA signal.

At this time, the pulse delay delay adjustment capacitor 570 connected to the pulse delay delay adjustment terminals 1,2 and 509 and 510 may serve to adjust the delay time.

The analog latch 550 is a circuit part that temporarily stores the detection information of each detection sensor 510 in the form of high and low signals, and the detection information of the detection sensor 510 in the X, Y, and Z directions is measured in the X direction. The detection sensor flag terminal 513, the Y-direction detection sensor Flag terminal 512, and the Z-direction detection sensor Flag terminal 511 may be respectively output.

In addition, the analog Latch 550 may recognize the direction in which the nuclear explosion occurred after the system is normalized by using the detection information of the detection sensor 510 in the X, Y, and Z directions.

There may be a total of eight cases of information in each direction, and an approximate nuclear explosion prediction direction in each case may be defined as shown in FIG. 4.

For reference, in FIG. 4, High may mean that gamma radiation is detected, and Low may mean that gamma radiation is detected below a reference value.

Built in Test (560) provides a test function that can normally check the operation of each detection sensor 510 disposed in all directions, as a test signal that can be input through the Bulit in Test input terminal 514 terminal Light may be applied to each detection sensor 510 to confirm the operation.

The capacitor for adjusting the pulse delay time 570 adjusts the delay time from the generation of the NA signal to the generation of the NEF signal and the reset signal. The time constant value can be determined as the delay time.

6 is a flowchart illustrating a procedure of a method of implementing a nuclear alarm according to an embodiment of the present invention.

Hereinafter, in the description of FIG. 6, FIG. 6 will be described with reference to FIGS. 2 and 5 described above to understand the invention.

In step 610, the nuclear alarm 200 detects gamma radiation through each detection sensor disposed in each plane in the three-dimensional space.

As shown in FIG. 3, the radiation detector 210 arranges the Gamma detection photo diode 310 on the YZ plane for the X-direction detection, and the Gamma detection photo diode 320 for the X-direction detection. By arranging on the plane and placing the Gamma detection photo diode 330 on the XY plane for Z direction detection, gamma radiation detection in all directions can be made possible.

That is, the radiation detector 210 configures a detection sensor for detecting gamma radiation generated in a nuclear explosion in a geometric three-dimensional structure, thereby enabling detection of gamma radiation in all directions.

In operation 620, the nuclear alarm 200 identifies the current pulses output from each detection sensor according to the detection of the gamma radiation, and checks whether the identified current pulses are equal to or greater than a threshold level set by each detection sensor. Generate detection information for each detection sensor including the results.

For example, the detection information generation unit 220 detects each of the X, Y, and Z directions when the current pulse according to the size of the gamma radiation detected by each gamma radiation detection sensor having a three-dimensional geometry is greater than or equal to a predetermined threshold level. The sensing information about the sensor may be generated at a high level or a low level and stored in the memory unit 240.

In this case, the threshold level adjusting unit 270 may adjust the threshold level of the current pulse for each detection sensor.

For example, as a result of the check, when at least one current pulse among the current pulses generated by each detection sensor is checked at or above a threshold level, the signal generator 250 may generate a first control signal (eg, an NA signal). In addition, a crowbar circuit 280 that temporarily shuts off power to main circuits may be operated to prevent thermal damage of electrical and electronic devices due to nuclear explosion.

As a set delay time is generated from the generation of the first control signal, the signal generator 250 generates a second control signal (eg, an NEF signal) to operate the crowbar circuit 280. Can be stopped (ie powered up) and a Reset signal can be generated to normalize the system.

At this time, the condenser unit 260 is a time constant value expressed as a product of the resistance R and the condenser C, for example, a delay time for generating the second control signal from the time when the first control signal is generated. Can be set.

In operation 630, the nuclear bomb alarm 200 predicts a direction in which the gamma radiation is input based on the generated detection information.

That is, the direction predictor 230 stops the operation of the crowbar circuit 280 after the set delay time elapses and the power is applied to the main circuit. By detecting the direction in which gamma radiation is immediately input using the sensing information of the detection sensor, it is easy to predict the direction in which the nuclear explosion occurred.

As in the case 420 illustrated in FIG. 4, the direction predicting unit 230 has high level of sensing information on the X-direction detection sensor disposed in the YZ plane, and the Y-direction, Z disposed in the XZ plane and the XY plane. When the sensing information of the direction detecting sensor is at a low level, the direction in which the gamma radiation is input may be predicted in the X-axis direction.

Alternatively, as in the case 430 illustrated in FIG. 4, the direction predicting unit 230 has high-level sensing information on the X-direction and Y-direction detection sensors disposed on the YZ plane and the XZ plane, and is disposed on the XY plane. When the sensing information of the detected Z-direction detection sensor is at a low level, the direction in which the gamma radiation is input may be predicted as an intermediate direction between the X-axis and the Y-axis.

Alternatively, as in the case 410 shown in FIG. 4, when the sensing information for each detection sensor is all at a high level (that is, when each of the current pulses are all identified above a threshold level), nuclear explosions at adjacent distances are performed. It can inform the direction detection failure due to the occurrence.

Therefore, according to an embodiment of the present invention, based on the detection information of each gamma radiation detection sensor having a three-dimensional geometry, by detecting the direction in which the gamma radiation is input, it is possible to easily predict the direction in which the nuclear explosion occurred do.
