- FIGS. 3A and 3B are conceptual views illustrating main components of a composite infrared sensor using an image of the present invention
- FIG. 4A is a diagram of a composite infrared sensor using an image according to the present invention.
- the infrared sensor 100 of the present invention is composed of a TX module TX for transmitting infrared rays and an RX module RX for receiving infrared rays and converting them into electrical signals.
- the shielding signal of the RX module of the infrared sensor when the shielding signal of the RX module of the infrared sensor is detected, the monitoring area is sensed by an image sensor, and the actual wavelength is determined in detail according to whether infrared wavelength and shape information are detected in the sensed image (image).
- the composite infrared sensor of the present invention will be described in detail.
- the composite infrared sensor 100 receives an infrared wavelength transmitted from a TX module and transmits the received infrared wavelength to the RX module RX and the RX module RX.
- the shading signal is detected by analyzing the image information captured by the camera module 120 consisting of the narrow-angle lens 121, the image sensing unit 122, the sensing area setting unit 123, the infrared wavelength and shape information in the image Detection signal, IR detection signal and shape information signal of the image analysis module 124 and the RX module RX, which transmits a signal analyzing whether the signal is detected to the detection signal processing unit 130, an appropriate alarm command signal And a detection signal processor 130 for classifying the false alarm signal and transmitting the alarm signal to the alarm receiver 140.
- the above-mentioned narrow angle lens 121 of the camera module 120 is to improve the infrared wavelength detection and shape recognition rate by minimizing the sensing area of the image by the image sensor 122 to increase the analysis speed and resolution during image analysis.
- the image detection range of the image captured by the narrow angle lens 121 may be adjusted by the sensing area setting unit 123.
- a fixed manual iris method may be adopted as the narrow angle lens 121.
- the image sensor 122 is installed in the camera module 120 to detect the infrared wavelength transmitted from the TX module TX as an image and update a predetermined amount of time in the image storage device 124a (memory) of the image analysis module 124. To be updated in such a way as to:
- any technique capable of detecting the presence or absence of infrared rays in the image sensed by the image sensor 122 can be employed without difficulty.
- Preferred employment examples according to the image analysis employed in the present invention are as follows.
- infrared detectors use infrared LEDs with a near-infrared wavelength band of 880 nm, and the spectral distribution characteristics of infrared LEDs range from about 700 nm to about 1 ⁇ m around 880 nm. Since the red light of the infrared LED is visible to the naked eye, there is an advantage that it is easy to check or adjust the operation.
- Visible light visible to the human eye is 350 ⁇ 740nm wavelength band, so the light emitting state of the infrared LED appears slightly bright red with the naked eye but very bright on the image sensor side.
- the sensitivity characteristics in the near infrared region of the image sensor are more sensitive than the human eye.
- the light emission state of the infrared LED is enlarged by the image sensor, and the light emission state and the transmission state of the infrared LED portion are utilized. By analyzing the change in the image level according to the data in real time, the false alarm rate of the infrared sensor can be significantly lowered.
- the emission level of the infrared LED shown during the day is lower than the night on the screen because the ambient illumination is bright. Since this occurs because of the operation of the auto iris of the image sensor, the brightness of the image sensor must be kept constant so that the value of the image level is kept constant. Therefore, if the fixed iris is fixed by adjusting it in the daytime bright state, and the brightness value of the image level is read by extracting the image part where the infrared LED emits light, the value of the image level does not change regardless of the day / night. Changes in image level occur due to snow, rain, fog, leaves blowing in the wind, and castles that cover winters.
- Infrared alarms must be blocked for a certain period of time in any case.
- the image level value of the image sensor is recognized as an intrusion state only when it becomes '0' for a certain time. If the infrared beam is blocked and the '0' value of the image level coincides simultaneously, and the exception is the case where the infrared RX module is broken, the shape is detected when the level of the infrared wavelength is small or "0" in the image information. If only false alarm is detected, all other alarm conditions are treated as false alarms.In case of false alarms, the detection signal processor sends all data related to this, that is, the reception level value and the image level value of the infrared sensor to the manager server. Identify the cause of false alarms.
- the image of the infrared transmitting LED captured by the image sensor should be captured as large and clear as possible with a small deviation of the calculation value of the usual image level, and the background illumination should be dark.
- the background of the infrared LED is the cover of the infrared sensor, and the cover is made of polycarbonate material which is dark red to facilitate the passage of the infrared beam, so there is no need to darken the background separately, but the size of the infrared LED is very large in image size. If too small is displayed on the screen because of the small size, the brighter portion is displayed during image processing, and the amount of computation of the image level is also reduced, which may cause a large deviation.
- the zoom magnification needs to be made as large as possible.
- the maximum installation distance of the infrared detector does not exceed 100m to facilitate the installation and maintenance, according to the present invention, when the maximum installation distance 100m, a lens having a focal length of 100mm or more may be required, and the sensing area setting unit 123 (See FIG. 4A), an appropriately set image range calculated in inverse proportion to the number of pixels of the image sensor can achieve the desired performance even under 50 mm.
- the 25 mm lens can be used in inverse proportion.
- the received video signal is normally recognized as a background screen, and when a new video signal (object shape) is sensed by the image sensor 122, irrespective of whether or not an infrared wavelength is received in the video information, Upon receiving the light blocking signal transmitted from the RX module RX, the alarm signal and the image information are transmitted to the security facility integrated management system 200 through both communication modules 210A and 210B.
- the detection signal processing unit 130 transmits the alarm signal and the image information to the image information stored in the image storage device 124a before / after the alarm signal transmission for a predetermined time, preferably before / after the alarm signal transmission 10 Send a second video.
- the detection signal processor 130 may be installed in the complex infrared sensor receiver receiver 100 or may be installed at an alarm reception and command device 211 and communicate with the image analysis module 124 as shown in FIG. 4B. It may be installed between the modules 210A. In the former case, it can be prevented from being damaged together when the complex IR sensor receiver 100 is damaged, and it is useful when constructing an integrated management system for multiple security facilities, and in the latter case, it is useful for implementing an independent security facility management system.
- the image storage device is installed in the image analysis module 124, and the alarm receiving and issuing device 211 of the security facility integrated management system 200.
- two pairs of lines of the communication module 210A and 210B are used to transmit an alarm signal (contact signal) to one pair and to transmit the image to the twisted pair transmission method to the other pair, or to use a power line communication method. Can be.
- Control processing of the received signal output value of the detection signal processing unit 130 and the alarm command signal corresponding to the infrared detection signal output value in the image will be described in more detail in the control method of the infrared sensor.
- FIG. 4B is a block diagram illustrating a main configuration of the integrated security facility management system 100 using the infrared sensor shown in FIGS. 3A and 3B.
- the integrated security facility management system 200 is a specific diagram.
- the infrared sensor 100 and the camera installed at a specific location or space of the facility are connected to the communication module 210A having a unique IP, and the alarm signal and the image analysis module 124 of the RX module RX are connected.
- Manager server 220 for storing infrared wavelength detection signal and shape detection signal in the image, transmission date information and false alarm processing information (data), monitor 230 for observing the processing signal or image information transmitted from a remote place; And a communication module 210B and an alarm receiving and initiating device 211 that communicate with the facility side communication module 210A.
- the integrated security facility management system 200 based on the infrared sensor 100 of the present invention communicates information (data transmission) and control signals through communication modules (210A) (210B) installed on each facility and the manager side, respectively. This is done.
- FIG. 5 is a flowchart illustrating control processing of a composite infrared sensor using an image according to the present invention.
- the output value is transmitted to the detection signal processing unit, and when the light reception signal is not detected by shading, the output value is output to "1" to the detection signal processing unit. If the received signal is below the set range, the output value transmits "2" to the detection signal processor.
- the output value 1 is transmitted to the detection signal processor, and in the opposite case, "0" is transmitted to the detection signal processor.
- the output value transmits "1" to the detection signal part and, in the opposite case, "0".
- control signal processing unit corresponding to the reception state of the output value of the RX module and the result output value of the image analysis module 124 is shown in Table 1 below.
- situation 1 is a situation where the received signal is received above the set value, so the infrared sensor can be confirmed that it is operating normally, and the infrared wavelength is not detected in the image by image analysis. It can be judged that there is no situation.
- situation 2 indicates that the infrared wavelength is detected in the image as a result of the image analysis, but the infrared ray is blocked before the light is received in the surveillance area, so the penetration of the security facility is seriously suspected, or the abnormality or failure of the RX module (RX) is suspected. Therefore, for the security of the through-the-air security facility integrated management system (200) transmits the false alarm signal (caution alarm) and at the same time by transmitting the video information, the administrator directly monitors and observes the situation and the RX module of the infrared sensor (RX Plan your inspection.
- situation 3 is a situation where the received signal value is higher than the set value. Therefore, when the infrared sensor is normally operated or when the infrared wavelength is detected in the image as a result of image analysis, the penetration attempt cannot be predicted. It only corresponds to a case where fallen leaves or other obstacles pass momentarily in the sensing area, the detection signal processor 130 transmits and stores a false alarm signal to the manager server 220.
- situation 4 indicates that the received light signal and the infrared wavelength detection signal are normal, but only the object shape is detected. Therefore, the fallen leaves, insects, birds, etc., did not block the infrared beam, or the intruder talked over the height of the infrared beam. Since the situation can be assumed, administrators should check the situation by sending false alarm signals and video information.
- situation 5 indicates that the received signal is shielded and the result of image analysis indicates that the infrared wavelength is not detected in the image, so that the detection signal processor 130 may be integrated into the security facility integrated management system 200.
- the administrator can immediately go to the site or monitor the detailed situation directly.
- the shape detection since the shape detection is not performed, it may be an alarm due to the sensing of a small object such as a bird or a cat. Therefore, the field check is required. When the shape detection is judged to be a "small bird", the alarm is canceled or not issued.
- situation 6 is a situation in which the received signal is blocked and the infrared wave is detected in the image as a result of the image analysis, but since the object shape is detected, it can be determined as a penetrator. Therefore, the detection signal processor 130 is an integrated security facility management system (200). By sending an emergency command signal and transmitting video information at the same time, the administrator can immediately go to the site or monitor the detailed situation directly, and analyze the video to analyze the situation where the infrared wavelength is continuously detected and check the camera.
- the video analysis module 124 and the detection signal processor are arranged to check for abnormalities.
- situation 7 indicates that the received signal is normal but the infrared wavelength is not detected in the image as a result of image analysis, and since the object shape is detected, it may be determined as a penetrator. Therefore, the detection signal processor 130 is an integrated security facility management system. Transmitting an emergency command signal to the 200 and simultaneously transmitting image information, the manager can immediately dispatch to the site or check the detailed situation directly through monitoring, and analyze the image to receive an infrared light signal without being blocked. Analyze and plan the inspection of the receiver of the infrared sensor.
- situation 8 is a situation in which the received signal is blocked, the infrared wavelength is not detected in the image, and the object shape is detected, so that the perfect penetrator can be determined. Therefore, the detection signal processor 130 integrates the security facilities.
- the emergency command signal (alarm signal) is transmitted to the management system 200, and at the same time, the image information is transmitted so that the administrator can immediately go to the site or monitor the detailed situation directly from the remote.
- the situation 9 and 10 indicates that the received signal value is less than or equal to the previously stored setting value, so it means a sensor failure, a poor reception sensitivity, or a decrease in sensitivity due to weather. Therefore, the detection signal processing unit 130 may detect whether or not infrared rays are detected. Infrared sensor check request signal is sent to the administrator to check the infrared sensor.
- the detection signal processing unit 130 issues a false alarm signal, a sensor check request signal, a caution alarm signal, and an emergency command signal by combining the received signal output value and the reception status, the infrared wavelength output value of the image and the shape detection signal.
- the video of 10 seconds before and after the basis of the occurrence of the caution alarm, emergency occurrence alarm to the integrated management system 200, the administrator can immediately respond to the occurrence of a situation that requires a substantial response.
- the infrared sensor 100 can reduce unnecessary false alarms and accurately determine and issue only necessary alarms, so that an administrator can immediately respond to an emergency situation such as a penetration penetrator, and also if there is an abnormality of the infrared sensor from a remote location.

Description

무인 감시시스템은 유료 및 가스 저장소, 탄약고 혹은 무기고와 같이 보안시설물(이하 "보안시설물"이라 함)의 엄격한 출입통제와 보안시설물의 상태나 상황을 원격지에서 실시간으로 효과적으로 관리 및 파악할 수 있는 장점이 있어 널리 보급되고 있다.The unmanned surveillance system has the advantages of strict access control of security facilities (hereinafter referred to as "security facilities"), such as paid and gas storage, ammunition or arsenal, and the effective management and grasp of the status and situation of security facilities in real time at a remote location. It is widely spread.
무인감시시스템은 보안시설물의 울타리나 건물의 내외벽 혹은 출입구 혹은 보안이 취약한 공간이나 장소에 카메라나 침투 감지용 센서 및 통합관리장치와 통신하는 통신장치로 구현되어 있다.The unmanned surveillance system is implemented as a communication device that communicates with a camera, a penetration detection sensor, and an integrated management device on a fence of security facilities, inside and outside walls of a building, an entrance, or a space or a place where security is vulnerable.
본 발명은 침투감지용 감시센서와 관련되는 것으로, 특히 적외선 감지센서와 관련된다.The present invention relates to a penetration detection monitoring sensor, in particular to an infrared detection sensor.
도 1은 종래의 적외선 감지센서 중 RX모듈 구성을 예시한 블럭 다이야그램으로, 적외선 감지센서의 구성과 작용효과를 설명한다.1 is a block diagram illustrating a configuration of an RX module of a conventional infrared sensor, and describes the configuration and effect of the infrared sensor.
적외선 감지센서는 TX모듈(도면에는 미도시)에서 복사된 적외선을 수광하는 RX모듈(11), 수광된 신호를 증폭시키는 증폭부(12), 증폭된 광신호를 설정값과 비교판단하는 수광량판별부(13), 차광시간을 판단하는 차광시간 비교부(14) 및 경보를 발령하는 경보수신 및 발생장치(15)로 구성되어 있다.The infrared sensor includes an RX module 11 for receiving infrared radiation radiated from a TX module (not shown), an amplifying unit 12 for amplifying the received signal, and a light quantity discrimination for comparing the amplified optical signal with a set value. The unit 13 includes a light shielding time comparison unit 14 for determining the light shielding time and an alarm receiving and generating device 15 for issuing an alarm.
증폭부(12)는 광전변환부를 구비하는 RX모듈(11)이 수신한 적외선 파형을 증폭하여 수광량판별부(13)로 출력하고, 수광량판별부(13)는 증폭부(12)에서 출력되는 증폭된 수광신호값을 미리 설정한 설정값과 비교하여 수광신호값이 설정값보다 적으면 적외선이 수광 전에 차광된 것으로 판단하고, 차광신호를 차광시간 비교부(14)로 전송한다.The amplifier 12 amplifies the infrared waveform received by the RX module 11 including the photoelectric conversion unit and outputs it to the light receiving amount discriminating unit 13, the light receiving amount discriminating unit 13 is amplified output from the amplifier 12 When the received signal value is less than the set value, the received light signal value is determined to be less than the set value, and it is determined that infrared light is blocked before light reception, and the light shielding signal is transmitted to the light shielding time comparison unit 14.
차광시간 비교부(14)는 차광여부를 판단하기 위해 미리 차광시간을 설정하여 저장한 뒤 차광이 진행된 시간을 카운트하여 차광시간이 설정된 시간보다 길 경우 경보신호를 경보수신 및 발생장치(15)로 전송하여 특정 경보를 발령한다.The shading time comparison unit 14 sets and stores shading time in advance to determine whether shading is performed, counts the time that shading proceeds, and sends an alarm signal to the alarm receiving and generating device 15 when the shading time is longer than the set time. Send a specific alarm.
도 2는 종래의 적외선 감지센서의 RX모듈의 차광을 센싱하여 경보를 발령하는 제어프로세스를 예시한 플로우챠트로서, RX모듈(11)에서는 수광된 수광신호값을 계산(S1)한 후 그 계산값과 미리 설정한 값을 비교(S2)하여, 계산값이 설정값보다 적을 경우(S3) TX모듈로부터 송신된 적외선 파장이 차광된 것으로 판단한다.FIG. 2 is a flowchart illustrating a control process of sensing light shielding of an RX module of a conventional infrared sensor and triggering an alarm. In the RX module 11, the received light signal value is calculated (S1) and then calculated. And a predetermined value are compared (S2), and when the calculated value is less than the set value (S3), it is determined that the infrared wavelength transmitted from the TX module is shielded.
따라서, 차광된 시점부터 시간을 카운팅(S4)하여 계산된 차광시간을 설정시간과 비교(S5)하여 차광시간이 설정시간보다 길 경우, 감시영역이 특정 물체에 의해 차단(해제)된 것으로 판단하여 경보를 발생(S6)한다.Therefore, when the shading time is longer than the set time by comparing the shading time calculated by counting the time from the time of shading (S4) to the set time (S5), it is determined that the monitoring area is blocked (released) by a specific object. Generate an alarm (S6).
전술한 바와 같은 종래의 적외선 감지센서는 사전에 설정한 차광시간보다 적은 시간내에 즉, 빠른 속도로 침투한다면 RX모듈(11)은 차광을 감지하지 못하는 허점이 생길 수 있다.As described above, the conventional IR sensor may have a loophole in which the RX module 11 does not detect shading if it penetrates in less than a predetermined shading time, that is, at a high speed.
또한 적외선 감지센서는 TX모듈이나 RX모듈의 이상이나 손상에 의한 센싱감도가 저하되면, 보안상 큰 허점이 발생하므로 관리자는 적외선 감지센서의 작동상태를 수시로 점검하고 있으나, 적외선 감지센서는 광범위한 지역에 분포되어 있고, 또 손이 잘 닿지 않은 높은 곳에 설치되어 있으므로, 수신측 적외선 감지센서의 커버를 벗겨서 수신전압을 측정하는 방식으로 센서의 이상 유무를 점검하는 것은 매우 번거롭고 불편하다.In addition, when the sensitivity of the infrared sensor is reduced due to abnormality or damage of the TX module or the RX module, a large loophole occurs in the security. Therefore, the administrator frequently checks the operation status of the infrared sensor. Since it is distributed and installed in a high place where it is hard to reach, it is very cumbersome and inconvenient to check the abnormality of the sensor by removing the cover of the receiving infrared sensor and measuring the received voltage.
적외선 감지센서의 수광감도가 저하되는 주된 이유는 센서 설치 후 시간경과로 인한 경년변화, 강풍 혹은 태풍과 같은 환경에 의해 고정상태 변경, 외부 충격, 계절적 온도변화나 일기변화, 센서점검 시 벗긴 외장케이스 재조립 시 센서위치변경 등 다양한 이유로 발생된다.The main reason why the sensitivity of the infrared light sensor is lowered is the change of the fixed state, external shock, seasonal temperature change or weather change, and the outer case removed during the sensor inspection. It is caused by various reasons such as sensor position change when reassembly.
적외선 감지센서의 센싱감도 점검은 대부분 전용테스터기를 수광신호 광전변환부에 연결하여 수신전압을 측정하는 방식으로 이루어지지만 적외선 감지센서가 고장나거나 센싱(수광)감도가 떨어진 상태에서 작동하더라도 관리자가 인이를 지하지 못한 상태에서 무인 감시시스템이 운용되므로 보안상 허점이 발생되기도 한다.Most of the sensing sensitivity check of the infrared sensor is done by connecting a dedicated tester to the photoelectric conversion unit to measure the received voltage.However, even if the infrared sensor fails or operates under a low sensitivity, Since the unmanned surveillance system is operated without knowing this, security loopholes may occur.
특히 종래의 적외선 감지센서는 떨어지는 낙엽이나 흔들리는 나무가지에 의해 적외선이 차광되어도 경보를 발령하게 되므로 잦은 경보발령은 적외선 감지센서의 신뢰성을 크게 저하시키는 문제로 작용한다.In particular, the conventional infrared sensor is an alarm even if the infrared rays are blocked by falling leaves or shaking tree branches, so frequent alarms act as a problem that greatly reduces the reliability of the infrared sensor.
본 발명은 전술한 바와 같은 문제를 해결하기 위해 안출한 것으로, 본 발명의 목적은 적외선 감지센서의 적외선 수신부의 수광신호 차광 시 이미지센서의 작동에 의해 얻어진 영상정보를 판별하여 침입시도 여부를 명확히 판별하여 불필요한 경보발령을 줄이고, 필요한 경보만을 발령함으로써 적외선 감지센서의 신뢰성을 증진시킬 수 있고, 또한 적외선 감지센서의 감도저하나 고장여부를 원격지에서 관리자가 바로 확인할 수 있으므로 불필요한 현장점검 없이 용이하게 센서를 점검할 수 있는 영상을 이용한 복합 적외선 감지센서를 제공하는 것이다.The present invention has been made to solve the above-described problems, an object of the present invention is to clearly determine whether the intrusion attempts by determining the image information obtained by the operation of the image sensor when shielding the received signal of the infrared receiver of the infrared sensor By reducing unnecessary alarms and issuing only necessary alarms, it is possible to enhance the reliability of the infrared sensor. Also, it is easy to check the sensor without unnecessary on-site inspection because the administrator can check the sensitivity of the infrared sensor or remotely. To provide a complex infrared sensor using an image that can be checked.

It is to provide a method of operation.
본 발명의 다른 목적은 적외선 파장을 미검출한 영상에서 미상의 물체형상이 있는지를 추출하여 영상정보만으로서 경보신호와 오경보 신호를 명확히 판별하여 발령함으로써 신뢰성을 높일 수 있는 적외선 감지센서 동작방법을 제공하는 것이다.It is another object of the present invention to provide a method for operating an infrared sensor that can increase reliability by extracting whether there is an unknown object shape from an image of which infrared wavelength is not detected and clearly distinguishing and issuing an alarm signal and a false alarm signal using only image information. It is.

It is to provide a security facility integrated management system that integrates the alarm and video information transmitted from each infrared sensor by the integration through the communication module to manage the security facilities.

For reference, a detailed description thereof will be omitted since it is similar to a conventional infrared sensor (see contents described in the background art), which implements a function of determining an intrusion when infrared rays transmitted from the TX module TX are shielded.
다만 본 발명은 적외선 감지센서의 RX모듈의 차광신호 검출시 감시영역을 이미지센서로 센싱하여 센싱한 영상(이미지)속에 적외선 파장과 형상정보가 검출되는지 여부에 따라 종합하여 실질적인 침입여부를 세부적으로 판별하는 본 발명의 복합 적외선 감지센서에 대하여 상세히 설명한다.However, in the present invention, when the shielding signal of the RX module of the infrared sensor is detected, the monitoring area is sensed by an image sensor, and the actual wavelength is determined in detail according to whether infrared wavelength and shape information are detected in the sensed image (image). The composite infrared sensor of the present invention will be described in detail.
본 발명은 도 4a에 도시된 바와 같이 복합 적외선 감지센서(100)는 TX모듈에서 송신된 적외선 파장을 수광하여 검출신호처리부(130)로 전송하는 RX모듈(RX)과, RX모듈(RX)에 의해 차광신호가 검출되었을 때 협각렌즈(121), 이미지센싱부(122), 센싱영역설정부(123)로 이루어진 카메라모듈(120)에 의해 촬영된 영상정보를 분석하여 영상속에 적외선파장과 형상정보가 검출되는지 여부를 분석한 신호를 검출신호처리부(130)로 전송하는 영상분석모듈(124) 및 RX모듈(RX)의 수광 검출신호와 적외선 검출 유무신호 및 형상정보신호에 대응하여 적절한 경보발령신호와 오경보 신호를 구분하여 경보수신 및 발령장치로(140)로 전송하는 검출신호처리부(130)로 구성되어 있다.As shown in FIG. 4A, the composite infrared sensor 100 receives an infrared wavelength transmitted from a TX module and transmits the received infrared wavelength to the RX module RX and the RX module RX. When the shading signal is detected by analyzing the image information captured by the camera module 120 consisting of the narrow-angle lens 121, the image sensing unit 122, the sensing area setting unit 123, the infrared wavelength and shape information in the image Detection signal, IR detection signal and shape information signal of the image analysis module 124 and the RX module RX, which transmits a signal analyzing whether the signal is detected to the detection signal processing unit 130, an appropriate alarm command signal And a detection signal processor 130 for classifying the false alarm signal and transmitting the alarm signal to the alarm receiver 140.
전술한 카메라 모듈(120)의 협각렌즈(121)는 이미지센서(122)에 의해 이미지의 센싱영역을 최소화하여 영상분석 시 분석속도와 해상도를 높임으로써 적외선파장검출 및 형상 인식율을 향상시키기 위한 것이다.The above-mentioned narrow angle lens 121 of the camera module 120 is to improve the infrared wavelength detection and shape recognition rate by minimizing the sensing area of the image by the image sensor 122 to increase the analysis speed and resolution during image analysis.
협각렌즈(121) 에 의해 촬상된 영상은 센싱영역설정부(123)에 의해 영상검출범위가 조절될 수 있다. 센싱영역설정부(123)의 채용예는 협각렌즈(121)에 고정식수동조리개 방식을 채용할 수 있다.The image detection range of the image captured by the narrow angle lens 121 may be adjusted by the sensing area setting unit 123. As an example of employing the sensing area setting unit 123, a fixed manual iris method may be adopted as the narrow angle lens 121.
이미지센서(122)는 카메라모듈(120)에 설치되어 TX모듈(TX)에서 송신된 적외선 파장을 영상으로 감지하여 영상분석모듈(124)의 영상저장장치(124a, 메모리)에 일정시간 분량을 갱신하는 방식으로 업데이트 되도록 전송한다.The image sensor 122 is installed in the camera module 120 to detect the infrared wavelength transmitted from the TX module TX as an image and update a predetermined amount of time in the image storage device 124a (memory) of the image analysis module 124. To be updated in such a way as to:
영상분석모듈(124)은 영상저장장치(124a)에 저장되는 이미지(영상)을 분석하여 분석신호(ON=1, OFF=0)를 영상처리부로 전송한다.The image analysis module 124 analyzes an image (image) stored in the image storage device 124a and transmits an analysis signal (ON = 1, OFF = 0) to the image processor.
영상분석에 따른 바람직한 구현예로서는 이미지센서(122)에 의해 센싱된 영상속에 적외선의 유무를 검출할 수 있는 기술이면 무리없이 채용될 수 있다.As a preferred embodiment according to the image analysis, any technique capable of detecting the presence or absence of infrared rays in the image sensed by the image sensor 122 can be employed without difficulty.
본 발명에서 채용한 영상분석에 따른 바람직한 채용예는 다음과 같다.Preferred employment examples according to the image analysis employed in the present invention are as follows.
일반적으로 적외선감지기는 중심파장 880nm의 근적외선 파장대역의 적외선LED를 사용하고 있으며, 적외선LED의 분광분포특성은 880nm를 중심으로 약700nm~약1㎛ 파장대역까지이며, 동작 시에는 송신기 측의 송신용 적외선 LED의 적색광이 육안으로 보이므로 동작확인이나 조정이 용이하다는 이점이 있다.In general, infrared detectors use infrared LEDs with a near-infrared wavelength band of 880 nm, and the spectral distribution characteristics of infrared LEDs range from about 700 nm to about 1 μm around 880 nm. Since the red light of the infrared LED is visible to the naked eye, there is an advantage that it is easy to check or adjust the operation.
사람의 눈에 보이는 가시광선은 350~740nm 파장대역이므로 적외선 LED의 발광상태는 육안으로 볼 때는 약간 밝은 적색으로 보이나 이미지센서 측에서는 매우 밝게 나타난다.Visible light visible to the human eye is 350 ~ 740nm wavelength band, so the light emitting state of the infrared LED appears slightly bright red with the naked eye but very bright on the image sensor side.
이것은 이미지센서의 근적외선영역에서의 감도특성이 사람의 눈보다 더 민감하기 때문으로, 본 발명에서는 이러한 특성을 살려 적외선 LED의 발광상태를 이미지센서로 확대 촬상하고, 적외선 LED 부분의 발광상태와 전송상태에 따른 영상레벨의 변화를 데이터화하여 실시간 비교분석함으로써 적외선감지기의 오경보율을 현저하게 낮출 수 있는 것이다.This is because the sensitivity characteristics in the near infrared region of the image sensor are more sensitive than the human eye. In the present invention, the light emission state of the infrared LED is enlarged by the image sensor, and the light emission state and the transmission state of the infrared LED portion are utilized. By analyzing the change in the image level according to the data in real time, the false alarm rate of the infrared sensor can be significantly lowered.
보다 상세하게 설명하면, 주간에 보이는 적외선LED의 발광상태는 주변 조도가 밝기 때문에 화면상에서는 야간에 비하여 영상레벨이 낮게 나타난다. 이것은 이미지센서의 자동조리개의 동작 때문에 발생하는 것이므로 본 발명에서는 밝기상태를 일정하게 유지하여야 영상레벨의 값도 일정하게 유지되므로 자동조리개가 아닌 고정조리개 방식을 채택한다. 따라서 고정조리개의 값을 주간 밝은 상태에서 조정하여 고정시키고 적외선 LED가 발광하는 영상부분을 추출하여 영상레벨의 밝기값을 읽게 되면 주/야간 구분 없이 영상레벨의 값은 변하지 않으며, 단지 일기의 영향 즉 눈, 비, 안개, 바람에 날리는 나뭇잎, 겨울철 커버에 끼는 성에에 의하여 영상레벨의 변화가 발생한다. In more detail, the emission level of the infrared LED shown during the day is lower than the night on the screen because the ambient illumination is bright. Since this occurs because of the operation of the auto iris of the image sensor, the brightness of the image sensor must be kept constant so that the value of the image level is kept constant. Therefore, if the fixed iris is fixed by adjusting it in the daytime bright state, and the brightness value of the image level is read by extracting the image part where the infrared LED emits light, the value of the image level does not change regardless of the day / night. Changes in image level occur due to snow, rain, fog, leaves blowing in the wind, and castles that cover winters.
적외선감지기의 송/수신기 간에 주고받는 적외선 빔은 어떠한 경우이든 일정시간이상 차단이 되어야 침입경보가 발생한다. 마찬가지로 이미지센서의 영상레벨 값도 일정시간 이상 '0'상태가 되어야 침입상태로 인지된다. 적외선 빔의 차단과 영상레벨의 '0'값이 동시에 일치되는 경우와 예외의 경우로서 적외선 RX모듈이 고장인 경우를 가정하여 영상정보에서 적외선파장의 레벨이 작거나 "0"인 경우 형상이 검출되는 경우만이 경보상태로 인정되며, 이외의 모든 경보상태는 오경보로 처리되며, 검출신호처리부는 오경보발생 시에는 이와 관련된 모든 데이터 즉, 적외선감지기의 수신레벨 값과 영상 레벨값을 관리자 서버로 전송하여 오경보의 원인을 밝힐 수 있도록 한다.Infrared alarms must be blocked for a certain period of time in any case. Similarly, the image level value of the image sensor is recognized as an intrusion state only when it becomes '0' for a certain time. If the infrared beam is blocked and the '0' value of the image level coincides simultaneously, and the exception is the case where the infrared RX module is broken, the shape is detected when the level of the infrared wavelength is small or "0" in the image information. If only false alarm is detected, all other alarm conditions are treated as false alarms.In case of false alarms, the detection signal processor sends all data related to this, that is, the reception level value and the image level value of the infrared sensor to the manager server. Identify the cause of false alarms.
이미지센서가 촬상한 적외선 송신 LED의 영상은 평상시 영상레벨의 연산값의 편차가 작게 최대한 크고 선명하게 촬상되어야 하고 배경 조도는 어두워야 한다. 적외선 LED의 배경은 적외선감지기의 커버가 되며, 커버는 적외선 빔의 통과가 유리하도록 암적색을 띄는 폴리카보네이트 재질로 되어 있어 별도로 배경을 어둡게 할 필요는 없으나, 영상의 크기에 있어서는 적외선 LED의 크기가 아주 작기 때문에 화면상에 너무 적게 표시되면 마찬가지로 영상처리 시에도 밝게 표시되는 부분이 적어 영상레벨의 연산 량 또한 적어지기 때문에 편차가 커지는 현상이 발생할 수 있다. The image of the infrared transmitting LED captured by the image sensor should be captured as large and clear as possible with a small deviation of the calculation value of the usual image level, and the background illumination should be dark. The background of the infrared LED is the cover of the infrared sensor, and the cover is made of polycarbonate material which is dark red to facilitate the passage of the infrared beam, so there is no need to darken the background separately, but the size of the infrared LED is very large in image size. If too small is displayed on the screen because of the small size, the brighter portion is displayed during image processing, and the amount of computation of the image level is also reduced, which may cause a large deviation.
이를 처리하기 위해서는 협각렌즈를 사용하며, 최대한 줌(zoom)배율이 크게 제작할 필요가 있다. 일반적으로 설치와 유지보수가 용이하도록 적외선 감지기의 최대 설치거리는 100m을 넘지 않도록 하고 있으며, 이에 따라 본 발명에서도 최대 설치거리 100m시에는 초점거리100㎜ 이상의 렌즈가 필요할 수 있으며, 센싱영역설정부(123, 도 4a 참조)에서 이미지센서의 픽셀 수에 역비례하여 연산하는 이미지범위를 적절하게 설정하면 50㎜이하로도 소기의 성과를 달성할 수 있다.To deal with this, a narrow angle lens is used, and the zoom magnification needs to be made as large as possible. In general, the maximum installation distance of the infrared detector does not exceed 100m to facilitate the installation and maintenance, according to the present invention, when the maximum installation distance 100m, a lens having a focal length of 100mm or more may be required, and the sensing area setting unit 123 (See FIG. 4A), an appropriately set image range calculated in inverse proportion to the number of pixels of the image sensor can achieve the desired performance even under 50 mm.
즉 30만화소의 이미지센서(122, 도 4a 참조)를 사용할 때 100㎜렌즈와 120만화소의 이미지센서를 채용하면 역비례하여 25㎜렌즈를 사용할 수 있는 것이다. In other words, when using the 300,000 pixel image sensor 122 (refer to FIG. 4A), if the 100 mm lens and the 1.2 million pixel image sensor are used, the 25 mm lens can be used in inverse proportion.
검출신호처리부(130)는 도 4a에 도시된 바와 같이 RX모듈(RX)에 의해 전송되는 투광 및 차광신호(투광=0, 차광=1)를 수신하여 그에 대응하여 경보발령 여부와 형태는 프로그래밍된 제어 프로세싱에 따라 제어하고, 평상시에는 수신되는 영상신호를 배경화면으로 인식하고 있다가 이미지센서(122)에 의해 새로운 영상신호(물체형상)가 센싱되면 영상정보에 적외선 파장의 수광 유무를 불문하고, 상기 RX모듈(RX)에서 전송되는 차광신호를 수신하는 즉시, 경보신호와 영상정보를 양 통신모듈(210A)(210B)을 통해 보안시설물 통합관리시스템(200)으로 전송된다.The detection signal processing unit 130 receives the light emission and light shielding signals (light emission = 0, light shielding = 1) transmitted by the RX module RX as shown in FIG. 4A, and correspondingly, whether or not an alarm is issued is programmed. After the control is performed according to the control processing, the received video signal is normally recognized as a background screen, and when a new video signal (object shape) is sensed by the image sensor 122, irrespective of whether or not an infrared wavelength is received in the video information, Upon receiving the light blocking signal transmitted from the RX module RX, the alarm signal and the image information are transmitted to the security facility integrated management system 200 through both communication modules 210A and 210B.
이때 검출신호처리부(130)는 경보신호와 영상정보를 전송함에 있어 영상저장장치(124a)에 저장된 영상정보를 경보신호 전송 전/후 일정시간의 영상정보, 바람직하게는 경보신호 전송 전/후 10초의 영상을 전송한다. In this case, the detection signal processing unit 130 transmits the alarm signal and the image information to the image information stored in the image storage device 124a before / after the alarm signal transmission for a predetermined time, preferably before / after the alarm signal transmission 10 Send a second video.
검출신호처리부(130)는 복합적외선감지센서 수신기(100)내에 설치되거나 경보수신 및 발령장치(211)측에 설치될 수 있고, 도 4b에 도시된 바와 같이 영상분석모듈(124)과 시설물측 통신모듈(210A) 사이에 설치하여도 무방하다. 전자의 경우 복합적외선감지센서 수신기(100)의 손상시 함께 훼손되는 것을 방지할 수 있어 다중 보안시설물의 통합관리시스템 구축 시 유용하며, 후자의 경우 독립적인 보안 시설물 관리시스템 구현에 유용하다.The detection signal processor 130 may be installed in the complex infrared sensor receiver receiver 100 or may be installed at an alarm reception and command device 211 and communicate with the image analysis module 124 as shown in FIG. 4B. It may be installed between the modules 210A. In the former case, it can be prevented from being damaged together when the complex IR sensor receiver 100 is damaged, and it is useful when constructing an integrated management system for multiple security facilities, and in the latter case, it is useful for implementing an independent security facility management system.
검출신호처리부(130)를 복합적외선감지센서 수신기(100)내에 설치하는 경우, 영상저장장치는 영상분석모듈(124)내에 설치하고, 보안시설물 통합관리시스템(200)의 경보수신 및 발령장치(211)측에 설치하는 경우 통신모듈(210A)(210B)의 2쌍의 선로를 이용하여 1쌍에는 경보신호(접점신호)를 나머지 1쌍에는 트위스트페어 전송방식으로 영상을 전송하거나 전력선 통신방식을 이용할 수 있다.When the detection signal processing unit 130 is installed in the complex infrared sensor receiver receiver 100, the image storage device is installed in the image analysis module 124, and the alarm receiving and issuing device 211 of the security facility integrated management system 200. In the case of installation on the) side, two pairs of lines of the communication module 210A and 210B are used to transmit an alarm signal (contact signal) to one pair and to transmit the image to the twisted pair transmission method to the other pair, or to use a power line communication method. Can be.
검출신호처리부(130)의 수광신호 출력값과 영상내에 적외선 검출신호 출력값에 대응하는 경보발령신호의 제어 프로세싱은 이하의 적외선 감지센서의 제어방법에서 보다 상세히 설명될 것이다.Control processing of the received signal output value of the detection signal processing unit 130 and the alarm command signal corresponding to the infrared detection signal output value in the image will be described in more detail in the control method of the infrared sensor.
이하에서는 도 4a에 도시된 적외선 감시센서를 이용한 보안시설물 통합관리시스템의 구현예를 설명한다. Hereinafter will be described an implementation example of a security facility integrated management system using the infrared surveillance sensor shown in Figure 4a.
도 4b를 참조하면, 도 4b는 도 3a 및 3B에 도시된 적외선 감지센서를 이용한 보안시설물 통합관리시스템(100)의 주요구성을 예시한 블럭 다이야그램으로서, 보안시설물 통합관리시스템(200)은 특정 시설물의 특정위치나 공간에 설치되는 적외선 감지센서(100)와 카메라 등은 고유 IP를 지닌 통신모듈(210A)들이 연결되어 있고, RX모듈(RX)의 경보발령신호와 영상분석모듈(124)의 영상내 적외선 파장 검출신호 및 형상검출신호와 전송일시 정보 및 오경보 처리정보(데이타)를 저장하는 관리자 서버(220)와, 원격지에서 전송되는 처리신호나 영상정보를 관찰할 수 있는 모니터 (230) 및 시설물측 통신모듈(210A)과 통신하는 통신모듈(210B) 및 경보수신 및 발령장치(211)를 포함한다.Referring to FIG. 4B, FIG. 4B is a block diagram illustrating a main configuration of the integrated security facility management system 100 using the infrared sensor shown in FIGS. 3A and 3B. The integrated security facility management system 200 is a specific diagram. The infrared sensor 100 and the camera installed at a specific location or space of the facility are connected to the communication module 210A having a unique IP, and the alarm signal and the image analysis module 124 of the RX module RX are connected. Manager server 220 for storing infrared wavelength detection signal and shape detection signal in the image, transmission date information and false alarm processing information (data), monitor 230 for observing the processing signal or image information transmitted from a remote place; And a communication module 210B and an alarm receiving and initiating device 211 that communicate with the facility side communication module 210A.
따라서 본 발명의 적외선 감지센서(100)를 기반으로 하는 보안시설물 통합관리시스템(200)은 시설물과 관리자 측에 각각 설치된 통신모듈(210A)(210B)을 통해 정보(데이터 전송) 및 제어신호의 통신이 이루어진다.Therefore, the integrated security facility management system 200 based on the infrared sensor 100 of the present invention communicates information (data transmission) and control signals through communication modules (210A) (210B) installed on each facility and the manager side, respectively. This is done.
이하에서는 본 발명에 따른 영상을 이용한 적외선 감지센서 동작방법에 대하여 첨부된 도 5를 참조하여 설명한다.Hereinafter, a method of operating an infrared sensor using an image according to the present invention will be described with reference to FIG. 5.
도 5를 참조하면, 도 5는 본 발명에 따른 영상을 이용한 복합 적외선 감지센서의 제어 프로세싱을 예시한 플로우챠트이다.5, FIG. 5 is a flowchart illustrating control processing of a composite infrared sensor using an image according to the present invention.
먼저, RX모듈(RX)에서 수광된 신호가 미리 지정한 설정값 이상 검출시, 출력값은 0을 검출신호처리부로 전송하고, 차광에 의한 수광신호 미검출시 출력값은 "1"을 검출신호처리부로 출력하며, 수광된 신호가 설정된 범위 이하인 경우 출력값은 "2"를 검출신호처리부로 전송한다.First, when the signal received by the RX module RX detects a predetermined value or more, the output value is transmitted to the detection signal processing unit, and when the light reception signal is not detected by shading, the output value is output to "1" to the detection signal processing unit. If the received signal is below the set range, the output value transmits "2" to the detection signal processor.
또한 영상분석모듈(124)의 이미지센서에 의해 센싱된 영상속에 적외선 파장 미검출 시 출력값은 1을 검출신호처리부로 전송하고, 반대인 경우 "0"을 검출신호처리부로 전송한다.In addition, when the infrared wavelength is not detected in the image sensed by the image sensor of the image analysis module 124, the output value 1 is transmitted to the detection signal processor, and in the opposite case, "0" is transmitted to the detection signal processor.
또한 물체형상검출 시 출력값은 "1"을 검출신호부로 전송하고, 반대인 경우 "0"을 전송한다.When the object shape is detected, the output value transmits "1" to the detection signal part and, in the opposite case, "0".
검출신호처리부는 RX모듈의 출력값과 영상분석모듈(124)의 결과 출력값의 수신상태에 대응하는 제어 프로세싱은 아래의 표 1과 같다.The control signal processing unit corresponding to the reception state of the output value of the RX module and the result output value of the image analysis module 124 is shown in Table 1 below.
위 표 1에서 상황1은 수광신호가 설정값 이상으로 수신되는 상황이므로, 적외선 감지센서는 정상 작동되고 있음을 확인할 수 있는 상태이고, 영상분석에 의해 영상속에 적외선 파장이 미검출된 상태이므로 침입자가 없는 상황으로 판단할 수 있다.In Table 1 above, situation 1 is a situation where the received signal is received above the set value, so the infrared sensor can be confirmed that it is operating normally, and the infrared wavelength is not detected in the image by image analysis. It can be judged that there is no situation.

위 표 1에서 상황2는 영상분석 결과 영상속에 적외선 파장이 검출되었으나 감시영역에 적외선이 수광 전에 차광된 것이므로 보안시설물의 침투가 심각하게 의심되거나, RX모듈(RX)의 이상 혹은 고장이 의심되는 상황이므로 철통보안을 위해 원격지의 보안시설물 통합관리시스템(200)으로 오경보 신호(주의경보)를 전송하고 동시에 영상정보를 전송하여 관리자가 직접 모니터링하여 상황을 주시하고 관찰하도록 하고 적외선센서의 RX모듈(RX) 점검을 계획한다.In Table 1 above, situation 2 indicates that the infrared wavelength is detected in the image as a result of the image analysis, but the infrared ray is blocked before the light is received in the surveillance area, so the penetration of the security facility is seriously suspected, or the abnormality or failure of the RX module (RX) is suspected. Therefore, for the security of the through-the-air security facility integrated management system (200) transmits the false alarm signal (caution alarm) and at the same time by transmitting the video information, the administrator directly monitors and observes the situation and the RX module of the infrared sensor (RX Plan your inspection.
위 표 1에서 상황3은 수광 신호값이 설정값 이상으로 수신되는 상황이므로 적외선 감지센서는 정상 작동되는 상황이나 영상분석 결과 영상속에 적외선 파장이 검출된 결과를 종합해 보면, 침투시도는 예측할 수 없으나 단지 센싱영역에 낙엽이나 기타 장애물이 순간적으로 통과한 경우에 해당하므로 검출신호처리부(130)는 오경보 신호를 관리자 서버(220)로 전송하여 저장한다.In the above Table 1, situation 3 is a situation where the received signal value is higher than the set value. Therefore, when the infrared sensor is normally operated or when the infrared wavelength is detected in the image as a result of image analysis, the penetration attempt cannot be predicted. It only corresponds to a case where fallen leaves or other obstacles pass momentarily in the sensing area, the detection signal processor 130 transmits and stores a false alarm signal to the manager server 220.
위 표 1에서 상황4는 수광신호과 적외선 파장 검출신호는 정상인데 물체형상만을 검출한 상황이므로 낙엽, 곤충, 조류 등에 의하여 적외선 빔을 차단하지 않고 스쳐 지나간 상황이거나 침입자가 적외선 빔의 높이 이상으로 월담한 상황을 가정할 수 있으므로 오경보 신호와 영상정보를 전송하여 관리자가 직접 상황을 점검토록 한다.In Table 1 above, situation 4 indicates that the received light signal and the infrared wavelength detection signal are normal, but only the object shape is detected. Therefore, the fallen leaves, insects, birds, etc., did not block the infrared beam, or the intruder talked over the height of the infrared beam. Since the situation can be assumed, administrators should check the situation by sending false alarm signals and video information.
위 표 1에서 상황5는 수광신호가 차광되고 영상분석 결과 영상속에 적외선 파장이 미검출된 의미는 침투기도로 단정될 수 있는 상황이므로 검출신호처리부(130)는 보안시설물 통합관리시스템(200)으로 비상사태 발령신호를 전송하고 동시에 영상정보를 전송하여 관리자가 현장으로 즉시 출동하거나 모니터링을 통해 상세 상황을 직접 확인할 수 있게 한다. 단 형상검출이 안된 상태이므로 혹 조류 또는 고양이 등 작은 물체의 센싱에 의한 경보일 수 있으므로 현장 확인이 필요하며, 형상검출 시 "작은새"로 판단되면 경보취소 또는 경보 미발령상태가 된다.In Table 1 above, situation 5 indicates that the received signal is shielded and the result of image analysis indicates that the infrared wavelength is not detected in the image, so that the detection signal processor 130 may be integrated into the security facility integrated management system 200. By sending an emergency command signal and transmitting video information at the same time, the administrator can immediately go to the site or monitor the detailed situation directly. However, since the shape detection is not performed, it may be an alarm due to the sensing of a small object such as a bird or a cat. Therefore, the field check is required. When the shape detection is judged to be a "small bird", the alarm is canceled or not issued.
위 표 1에서 상황6은 수광신호가 차광되고 영상분석 결과 영상속에 적외선 파장은 검출되었으나 물체형상이 검출되었으므로 침투기도로 단정될 수 있는 상황이므로 검출신호처리부(130)는 보안시설물 통합관리시스템(200)으로 비상사태 발령신호를 전송하고 동시에 영상정보를 전송하여 관리자가 현장으로 즉시 출동하거나 모니터링을 통해 상세 상황을 직접 확인할 수 있게 하고 영상을 분석하여 적외선파장이 계속 검출되는 상황을 분석하고 카메라의 점검, 영상분석모듈(124), 검출신호처리부의 이상유무의 점검을 계획한다.In the above Table 1, situation 6 is a situation in which the received signal is blocked and the infrared wave is detected in the image as a result of the image analysis, but since the object shape is detected, it can be determined as a penetrator. Therefore, the detection signal processor 130 is an integrated security facility management system (200). By sending an emergency command signal and transmitting video information at the same time, the administrator can immediately go to the site or monitor the detailed situation directly, and analyze the video to analyze the situation where the infrared wavelength is continuously detected and check the camera. The video analysis module 124 and the detection signal processor are arranged to check for abnormalities.
위 표 1에서 상황7은 수광신호는 정상이나 영상분석 결과 영상속에 적외선 파장이 미검출되고, 물체형상이 검출되었으므로 침투기도로 단정될 수 있는 상황이므로 검출신호처리부(130)는 보안시설물 통합관리시스템(200)으로 비상사태 발령신호를 전송하고 동시에 영상정보를 전송하여 관리자가 현장으로 즉시 출동하거나 모니터링을 통해 상세 상황을 직접 확인할 수 있게 하고 영상을 분석하여 적외선 수광신호가 차광되지 않고 계속 수광된 상황을 분석하고 적외선센서의 수광부의 점검을 계획한다.In the above Table 1, situation 7 indicates that the received signal is normal but the infrared wavelength is not detected in the image as a result of image analysis, and since the object shape is detected, it may be determined as a penetrator. Therefore, the detection signal processor 130 is an integrated security facility management system. Transmitting an emergency command signal to the 200 and simultaneously transmitting image information, the manager can immediately dispatch to the site or check the detailed situation directly through monitoring, and analyze the image to receive an infrared light signal without being blocked. Analyze and plan the inspection of the receiver of the infrared sensor.
위 표 1에서 상황8은 수광신호가 차광되고, 영상분석 결과 영상속에 적외선 파장이 미검출되고, 물체형상이 검출되었으므로 완벽한 침투기도로 단정될 수 있는 상황이므로 검출신호처리부(130)는 보안시설물 통합관리시스템(200)으로 비상사태 발령신호(경보신호)를 전송하고 동시에 영상정보를 전송하여 관리자가 현장으로 바로 출동하거나 모니터링을 통해 원격에서 상세 상황을 직접 확인할 수 있게 한다.In the above Table 1, situation 8 is a situation in which the received signal is blocked, the infrared wavelength is not detected in the image, and the object shape is detected, so that the perfect penetrator can be determined. Therefore, the detection signal processor 130 integrates the security facilities. The emergency command signal (alarm signal) is transmitted to the management system 200, and at the same time, the image information is transmitted so that the administrator can immediately go to the site or monitor the detailed situation directly from the remote.
위 표 1에서 상황9와 10은 수광 신호값이 미리 저장한 설정값 이하이므로 센서 고장이나 수신감도 불량 또는 일기에 의한 감도저하를 의미하므로, 적외선의 검출 여부를 불문하고 검출신호처리부(130)는 관리자에게 적외선 감지센서 점검요청신호를 전송하여 적외선 감지센서를 점검할 수 있도록 한다. In the above Table 1, the situation 9 and 10 indicates that the received signal value is less than or equal to the previously stored setting value, so it means a sensor failure, a poor reception sensitivity, or a decrease in sensitivity due to weather. Therefore, the detection signal processing unit 130 may detect whether or not infrared rays are detected. Infrared sensor check request signal is sent to the administrator to check the infrared sensor.
결론적으로, 상황8을 제외한 상황5 내지 상황 7은 침입경보가 확실하기는 하나 보안관리 시스템내 어딘가에 문제점이 있다는 것을 증빙하는 것이므로 상황종료 후 시스템 점검이 필요하다는 것을 말한다. In conclusion, Situation 5 to Situation 7 except Situation 8 proves that there is a problem in the security management system although the intrusion alarm is certain, so it is necessary to check the system after the termination of the situation.
전술한 바와 같이 검출신호처리부(130)는 수광신호 출력값 및 수신여부 및 영상속 적외선 파장 출력값과 형상검출신호를 종합하여 오경보 신호, 센서 점검요청신호, 주의경보신호, 비상사태발령신호를 발령하고, 주의경보, 비상사태발생경보 전송시 상황발생을 기준하여 전/후 10초 분량의 영상을 통합관리시스템(200)으로 전송함으로써 실질적인 대응이 요구되는 상황발생에 관리자가 바로 대응할 수 있다. As described above, the detection signal processing unit 130 issues a false alarm signal, a sensor check request signal, a caution alarm signal, and an emergency command signal by combining the received signal output value and the reception status, the infrared wavelength output value of the image and the shape detection signal. By transmitting the video of 10 seconds before and after the basis of the occurrence of the caution alarm, emergency occurrence alarm to the integrated management system 200, the administrator can immediately respond to the occurrence of a situation that requires a substantial response.
영상정보전송 분량을 경보발령 전/후 10초로 설정한 것은 예시적인 것일 뿐 제작 시에는 시간 조정폭을 충분히 크게 설정하여야 할 것이다. Setting the video information transmission amount to 10 seconds before / after the alarm is only an example, and the time adjustment width should be set large enough during production.
그러므로 본 발명의 적외선 감지센서(100)는 불필요한 오경보를 줄이고 필요한 경보만 정확히 판별하여 발령함으로써 침투기도와 같은 긴급 상황발생 시 관리자는 즉시 상황에 대응할 수 있고, 또한 원격지에서 적외선 감지센서의 이상여부나 고장유무를 점검 혹은 확인할 수 있으므로 각 적외선 센서들을 찾아가 점검할 필요가 없어 편리하며, 또한 적외선 감지센서의 신뢰성이 매우 증진되는 효과가 있다. Therefore, the infrared sensor 100 according to the present invention can reduce unnecessary false alarms and accurately determine and issue only necessary alarms, so that an administrator can immediately respond to an emergency situation such as a penetration penetrator, and also if there is an abnormality of the infrared sensor from a remote location. Since it is possible to check or confirm the failure, it is not necessary to visit and check each infrared sensor, and the reliability of the infrared sensor is greatly enhanced.
본 발명은 보안시설물용 침입감시나 주요시설물 혹은 건물의 화재발생여부를 사전에 감지(연기발생감지)하기 위해 응용될 수 있다.The present invention can be applied to intrusion monitoring for security facilities or to detect in advance whether the fire of the main facility or building (smoke detection).
