The present invention relates to a radioactivity measuring device for a vehicle for biochemical vehicles that can be accurately and quickly detected.

In particular, the chemical reconnaissance vehicle is equipped with a remote chemical automatic alarm, an automatic chemical detector, and a radioactivity detector to perform other functions in the chemical unit. It is necessary to have a quick maneuverability and reconnaissance function in order to improve survival rate and maintain combat power by performing quick response measures. In addition, it should be possible to detect and identify a wide range of contaminated areas under biochemical conditions.

As shown in FIG. 3, the measurement device 1 is mounted inside the vehicle 10 and includes an internal radioactivity sensor 110 that detects radioactivity inside the vehicle 10.

The internal radioactivity sensor 110 measures the level of radioactivity inside the vehicle. Specifically, the radioactivity sensor 110 may measure the melody/dose of radioactivity, and may also be mounted on a vehicle or operated separately. The method for mounting on the vehicle is not particularly limited, and any method used in the technical field to which the present application belongs may be applied.

The internal radioactivity sensor 110 detects the radioactivity inside the vehicle 10 and, as long as it can perform a function of transmitting the detected data or signal to the control device 140, its form, operation method, etc. are particularly limited. It does not work.

In addition, as shown in FIG. 3, the measurement device 1 is mounted outside the vehicle 10 and includes a plurality of external radioactivity sensors 120 and 130 that detect radioactivity outside the vehicle 10. An external radioactivity sensor can also measure the melody/dose of radioactivity.

The external radioactivity sensors 120 and 130 detect the radioactivity outside the vehicle and, as long as they can perform a function of transmitting the detected data or signals to the control device, the form and operation method are not particularly limited.

A plurality of external radioactivity sensors 120 and 130 exist, for example, in the case of two, the first external radioactivity sensor 120 and the second external radioactivity sensor 130, and the first external radioactivity sensor 120 ) And the second external radioactivity sensor 130 may be disposed on the front left and right sides of the vehicle 10, respectively. However, the positions of the first external radiation sensor 120 and the second external radiation sensor 130 may be changed to some extent depending on the shape or size of the vehicle, but are arranged one by one on the left and right sides of the vehicle, respectively. Should be placed in front of you.

The first external radiation sensor 120 includes a first high-radiation radiation detector and a first low-radiation radiation sensor. In addition, the second external radiation sensor 130 includes a second high-radiation radiation sensor and a second low-radiation radiation sensor.

Here, the criterion for dividing the high and low melody is determined according to the detection performance of the sensor that can be applied to the present application. That is, the criteria may be flexible depending on the performance of the high and low luminosity sensors used in the design of the radiation sensor. The present application may be classified into a high melody sensor and a low melody sensor according to preset criteria according to sensor performance, detection range, and the like.

As will be described later, a wide-band radioactivity can be detected using a low-radiation radioactivity sensor and a high-radiation radioactivity sensor. In addition, through this, it is possible to more thoroughly measure radioactivity from contaminated areas that may exist on the left and right and front sides of a relatively large vehicle.

In addition, as shown in FIG. 3, the measurement device 1 includes a control device 140 that receives the measured data from an internal radiation sensor and a plurality of external radiation sensors to determine a radiation melody value.

The control device 140 may be electrically connected to the internal radiation sensor 110 and the external radiation sensors 120 and 130, respectively, to receive data or signals therefrom, or to transmit data or signals.

In addition, the control device 140 is also electrically connected to the vehicle 10, and may serve as a power source, communication, and external interface.

The measurement device 1 includes a display unit (not shown) that receives and displays data corresponding to the radiation melody value from the control device 140. Through the display unit, the user or the operator can confirm the melody value to be finally obtained.

The connection cable may be provided with more connections in order to be connected to more devices.

Another aspect of the present application relates to a chemical bio-vehicle vehicle including the above-described radiation measuring device for a chemical bio-vehicle vehicle.

External radiation sensors 120 and 130 are provided in a pair on the front left and right sides of the vehicle, and the radiation can be measured up to a relatively large vehicle, and each external radiation sensor 120 or 130 Including a high melody sensor and a low melody sensor, it is possible to measure a wide range of radioactivity.

Another aspect of the present application relates to a radioactive melody switching method of a radioactivity measurement method.

4 is a flowchart of a method for switching radioactivity in a radioactivity measurement method according to an embodiment of the present application.

As shown in FIG. 4, the first pulse data for the radiation melody measured from the first radioactivity sensor is received (S110); From the first pulse data, a first average melody value excluding the highest melody and the lowest melody is calculated, and the excluded melody and the first average melody are compared, and if the deviation of each section is greater than or equal to a section deviation, the result is equalized to the excluded melody and the first normalized melody Calculates (S120); Check whether the calculated value is included in the low or high melody range (130); When the calculated value is included in the low melody range, the first low melody sensor is selected (S131); When the calculated value is included in the high melody range, the first high melody sensor is selected (S132); Deriving a first melody value (S133); Receiving second pulse data for the radiation melody measured from the second radioactivity sensor (S220); From the second pulse data, calculate the second average melody value excluding the highest melody and the lowest melody, compare the excluded melody with the second average melody, and if it is more than the deviation of each section, normalize to the excluded melody, and the second normalized melody value Calculates (S220); Check whether the calculated value is included in the low or high melody range (S230); If the calculated value is included in the low melody range, select a second low melody sensor (S231); When the calculated value is included in the high melody range, a second high melody sensor is selected (S232), and a second melody value is derived (S233); The larger of the first melody value and the second melody value is displayed (S310).

If this is specifically examined, the first pulse data for the radiation melody measured from the first radiation sensor mounted on the exterior of the vehicle is received.

Here, the radioactivity pulse means all doses/radiances representing radiation doses. The dose is the total amount of radiation, and the international standard unit for absorbed radiation is 　Gy (gray). Also. The melody means the amount over time, and the unit is Gy/h.

The highest melody and the lowest melody are excluded from the received first pulse data, and a first average melody value is calculated from the remaining melody values.

Here, the meaning of changing from the first pulse data to melody means a process of measuring the amount of radiation and converting it into melody, which is an irradiation amount over time.

At this time, the excluded melody is compared with the first average melody value, and when the difference is judged to be equal to or greater than the deviation of each section, the first average melody value is equalized with the excluded melody to calculate the first normalized melody value.

In the present application, the leveling method may use a method (filter) called “moving average”. To explain this in detail, set the quantity to obtain the average, exclude the past data over time, and add the new data to obtain the average. By using the average of multiple data, it is possible to prevent sudden data fluctuation, and has the advantage of using input data immediately while using a large number of data. However, the moving average method has a disadvantage that the reactivity is limited. If the input value changes abruptly, the reflection of the value is delayed because it reflects the average with the previous data.

So, to solve this problem of reactivity, leveling can be performed. If the measured data is more than a certain deviation, this data is used first, and the data is recalculated as much as the moving average sample quantity from this data. This process is necessary in this application because immediate detection is more important than certain stable data from radioactive detection equipment.

Then, after confirming whether the calculated value is included in the low melody range or the high melody range, if the calculated value is included in the low melody range, the first low melody sensor is selected, and the calculated value is in the high melody range. If included, the first high melody sensor is selected to derive the first melody value.

Based on the second pulse data obtained from the second external radioactivity sensor, a second melody value is derived using the same method as the first pulse data described above. Then, the first melody value and the second melody value are compared and the larger of the two is displayed.

Through this, it is possible to improve the detection performance degradation phenomenon that occurs in the low-radiation and high-radiation sensor switching section of the radiometer.

Another aspect of the present application relates to a method for measuring radioactivity for a vehicle for biochemical vehicles, which uses the radioactive melody switching method of the above-described radioactivity measuring device, and the first radioactivity sensor and the second radioactivity sensor are disposed on the front left and right sides of the vehicle, respectively.
