Description

[0001] RADIOACTIVE SOURCE DETECTION SIMULATION TRAINING APPARATUS [0002]

The present invention relates to a radiation source detection simulation training apparatus, and more particularly, to a radiation source detection simulation training apparatus using a simulation radiation source for transmitting electromagnetic waves.

Radiation and radioactive materials are currently used in many industrial and medical applications. Excessive exposure to these radioactive and radioactive materials will cause serious damage to organs and tissues of the human body. In particular, workers exposed to high doses of radiation are more likely to be exposed to radiation.

In addition, when a radioactive terror such as a radioactive bomb occurs, the human body is exposed to the radioactive material scattered by the explosion, which causes serious damage and may lead to death depending on the radiation dose. Therefore, training to detect and recover radioactive materials immediately and to minimize damage is essential.

Currently, radioactive material detection and recovery training is conducted using low dose radiation sources for safety reasons. However, since the low dose radiation source is weak in intensity, it is difficult for the trainee to detect the low dose source using the radiation detector. Also, even a low-dose radiation source can cause serious damage to the trainee if exposed continuously.

Accordingly, the present invention provides a radiation source detection simulation training apparatus capable of more securely and efficiently performing radiation source detection simulation training.

In this specification, when a part is connected to another part, it includes not only a direct connection but also a case where the part is electrically connected with another part in between. In addition, when a part includes an element, it does not exclude other elements unless specifically stated otherwise, but may include other elements.

The terms first, second, third, etc. in this specification may be used to describe various components, but such components are not limited by these terms. The terms are used for the purpose of distinguishing one element from another. For example, without departing from the scope of the present invention, the first component may be referred to as a second or third component, and similarly, the second or third component may be alternately named.

In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

1 is a schematic diagram showing a radiation source detection simulation training apparatus according to the present invention.

Referring to FIG. 1, a radiation source detection simulation apparatus according to the present invention includes a simulated radiation source 100, a simulated detector 200, and a simulated dosimeter 300.

The simulated radiation source 100 transmits electromagnetic waves containing the radiation source information. That is, the simulated radiation source 100 emits an electromagnetic wave set to correspond to the kind and dose of the actual radiation source.

That is, the kind of the electromagnetic wave can be changed according to the kind of the actual radiation source, and the intensity of the electromagnetic wave can be changed according to the dose of the actual radiation. For example, the frequency of the electromagnetic wave can be set in proportion to the frequency of the radiation source, and the intensity of the electromagnetic wave can be set in proportion to the dose of the radiation source. However, the present invention is not limited thereto, and the type and intensity of the electromagnetic wave according to the type and intensity of the actual radiation source can be arbitrarily set. Such radiation source information can be input before training.

In addition, the simulated radiation source 100 periodically generates an electromagnetic wave corresponding to the preset radiation source information for the training time (for example, 3 hours) throughout the training time.

The simulated radiation source 100 may be a terminal capable of performing communication based on, for example, Zigbee (IEEE 802.15.4), which is an international standard, but the present invention is not limited thereto, and a radio frequency identification Or may be a terminal capable of communication.

The electromagnetic wave radiated from the simulated radiation source 100 may have a maximum signal range of about 20 m or less in radial form. However, the present invention is not limited thereto and the maximum signal range of the simulated radiation source 100 can be variously set according to the training purpose.

Since the simulated radiation source 100 must support mobility, it is preferable that the simulated radiation source 100 is small in size, and it is preferable to use an internal power source (for example, a battery) without using an external power source.

The training manager mounts the battery in the simulated radiation source 100 and applies power through the power button and initializes it. Then, various training information, such as the simulated radiation source 100 ID, the source type, The radiation source information such as the dose (intensity) and the like, and information such as the generation period of the electromagnetic wave.

Next, a plurality of simulated radiation sources 100 are placed in the training area. At this time, the non-radiation source 100 'having the same external shape as the simulated radiation source 100 may be disposed together to increase the training effect.

The simulator detector 200 detects the type and intensity of electromagnetic waves periodically transmitted from the simulated radiation source 100 using the IEEE 802.15.4-based ZigBee device.

Also, the simulation detector 200 can calculate the distance to the simulated radiation source 100 using the intensity of the sensed electromagnetic wave, for example, the received signal strength indicator (RSSI).

Specifically, the simulator detector 200 calculates the RSSI value of the received signal, which is obtained by sampling the RSSI value of the received signal for a few seconds, and the RSSI value between the simulated radiation source 100 and the simulated detector 200, The distance to the simulated radiation source 100 can be calculated by comparing the received signal electric field strength (RSSI)

2 is a view for explaining a distance calculating method of the simulator according to the present invention.

2, when the distance between the simulated radiation source 100 and the simulated detector 200 is 1 m, the previously stored received signal electric field strength (RSSI) value is -59 dbm. When the distance is 2 m, ) Value is -72 dBm, and when the RSSI value of the received signal detected by the actual simulation detector 200 is -65 dbm, the simulation detector 200 compares the RSSI value stored in advance with the received RSSI value It is possible to calculate that the simulated radiation source 100 is located in a space having a radius of 1 m or more and a radius of 2 m or less by comparing the received RSSIs.

The simulator detector 200 provides a received signal field strength (RSSI) value calculated by sampling a received signal field strength (RSSI) value sensed for a few seconds and a distance to the calculated simulated radiation source 100 in real time to a training participant do.

When there are a plurality of simulated radiation sources 100, the simulator detector 200 calculates the distance to each simulated radiation source 100 and provides the distance to the training participants in real time.

Also, the simulator detector 200 can output a warning sound when the distance to the calculated simulated radiation source 100 is smaller than a preset distance, that is, when it approaches the simulated radiation source 100. However, the present invention is not limited thereto, and vibration, an LED, or an alarm may be output.

Different warning sounds may be output depending on the distance from the simulated radiation source 100. For example, the closer to the simulated radiation source 100, the stronger beep sound can be output.

3 is a diagram exemplifying information displayed on the display unit of the simulation detector according to the present invention.

Referring to FIG. 3, the simulator 200 detects a simulated radiation source number (ID), a type of electromagnetic wave, an intensity of an electromagnetic wave (RSSI), a distance to a simulated radiation source 100, (Alarm1, Alarm2), and the like.

For example, the simulated detector 200 can display contents located within a radius of 8 m from the first simulated radiation source (ID 1) through a sensed electromagnetic wave, which is a radioactive substance called Na-22. In addition, since the predetermined warning display distance is less than 7 m and less than 5 m, the alarm indication (Alarm 1, Alarm 2) is not activated due to the first simulated radiation source (ID 1).

In addition, the simulated detector 200 can display the content of the second simulated radiation source (ID 2) through the sensed electromagnetic wave, which is a radioactive substance of Co-66 and located within a radius of 6 m. Also, since the preset warning display distance is less than 7m and less than 5m, the first warning indication (Alarm1) is activated due to the second simulated radiation source (ID2), while the second warning indication (Alarm2) is not activated.

The display unit of the simulated detector 200 can be used without limitation in a commonly used display apparatus. Such a display apparatus includes a liquid crystal display (LCD), an organic light emitting diode (OLED), and the like.

Information such as the type and intensity of the electromagnetic wave sensed by the simulation detector 200 and the distance to the calculated simulated radiation source 100 are transmitted to the external server 400 in real time via a WLAN configured by LAN and wireless . The various information transmitted to the external server 400 can be used as evaluation data after completion of the training.

The training participant may use the simulated detector 200 to detect the position of the simulated radiation source 100. One simulator detector 200 may be provided for each training participant or one for each training participant group.

The simulated dosimeter 300 calculates the amount of accumulated electromagnetic waves sensed by the simulated detector 200. The electromagnetic wave accumulation amount calculated by the simulated dose meter 300 can correspond to the actual radiation exposure amount. The simulation dose meter 300 can calculate the electromagnetic wave accumulation amount by using the distance to the simulation radiation source 100 calculated by the simulation detector 200. [

When there are a plurality of simulated radiation sources 100, the simulated dosimeter 300 can calculate the accumulated amount of electromagnetic waves from each simulated radiation source 100 and the accumulated amount of electromagnetic waves from the entire simulated radiation source 100. The simulated dosimeter 300 indicates the amount of electromagnetic waves accumulated continuously during the training time.

The simulation dosimeter 300 can output a warning sound when the calculated electromagnetic wave accumulation amount exceeds a predetermined electromagnetic wave accumulation amount. However, the present invention is not limited thereto, and vibration, an LED, or an alarm may be output. The predetermined electromagnetic wave accumulation amount can be set in advance based on the type and intensity of the simulated radiation source 100.

Different beeps can be output depending on the accumulated amount of electromagnetic waves. For example, as the electromagnetic wave accumulation amount increases, a stronger warning sound may be output.

In addition, the simulated dosimeter 300 may previously calculate an amount accumulated after a predetermined time according to the amount of the electromagnetic wave sensed by the simulated detector 200, and inform the training participant that the evacuation time has remained for a predetermined time. The time setting and the evacuation time setting can be set variously according to the situation.

4 is a diagram exemplarily showing information displayed on the display unit of the simulated dosimeter 300. Fig.

4, the simulated dosimeter 300 includes a simulated radiation source ID, a source of electromagnetic waves, an intensity of electromagnetic waves (RSSI), a distance to a simulated radiation source 100, Alarm2), and the evacuation time (minute), and the like.

For example, the simulated dosimeter 300 can calculate the cumulative amount of electromagnetic waves (ID1-40, ID2-52) due to each simulated radiation source and the total amount of cumulative electromagnetic accumulation (All-168) due to the entire simulated radiation source.

Also, since the preset alarm display accumulation amount is over 100 and over 200, the first alarm indication (Alarm 1) is activated due to the total electromagnetic accumulation amount (All - 168), while the second alarm indication (Alarm 2) is not activated.

In addition, the amount of accumulation after a predetermined time may be calculated in advance according to the preset maximum electromagnetic wave accumulation amount and the amount of electromagnetic waves accumulated up to now, and the training participant may display that the evacuation time is 75 minutes.

The display unit of the simulated dosimeter 300 can be used without limitation in a commonly used display apparatus. Such a display apparatus includes a liquid crystal display (LCD), an organic light emitting diode (OLED), and the like.

Information such as the amount of accumulated electromagnetic waves measured by the simulated dosimeter 300 can be transmitted to the external server 400 in real time via a WLAN configured by LAN and wireless.
