Description

TECHNICAL FIELD [0001] The present invention relates to an infrared sensor using images, an operation method thereof, and an integrated management system for security facilities using the infrared sensor,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an infrared ray detection sensor (hereinafter, referred to as an 'infrared ray detector') for detecting intrusion of a security facility, and more particularly, It is possible to determine whether the infrared signal is detected in the image information of the surveillance region photographed by the camera module installed on both sides of the region and whether the detection of the object shape (including the human shape) It improves the efficiency of management of security facilities, enables accurate identification of infiltration location, infiltration and escape route as well as intrusion prayer, and enables the administrator to check the sensitivity of the infrared detector or whether it is faulty. Infrared image using image that can easily check the abnormality of the infrared sensor from the remote It relates to a group, and its method of operation and security facilities, integrated management system using the same.

The unmanned surveillance system has the advantage of strict access control of security facilities (hereinafter referred to as "security facilities") such as pay-for-use and gas storage, ammunition or armory, Is becoming popular.

The unmanned surveillance system is implemented as a communication device that communicates with sensors or integrated management devices for detecting cameras or infiltration airways in a fence of a security facility, an inside or outside wall or entrance of a building, or a space or place where security is weak.

Since the present invention relates to an infrared ray detector, the technical background of an infrared ray detector will be described first.

FIG. 1 is a block diagram illustrating a configuration of an RX module among conventional infrared detectors. The configuration and operation of a conventional infrared ray detector will be described.

The infrared ray detector includes an RX module 11 for receiving infrared rays irradiated from a TX module (not shown in the figure), an amplifying unit 12 for amplifying the received signal, a light receiving amount determining unit A light-shielding time comparator 14 for determining a light-shielding time, and an alarm receiving and generating device 15 for issuing an alarm.

The amplification unit 12 amplifies the infrared waveform received by the RX module 11 having the photoelectric conversion unit and outputs the amplified infrared waveform to the received light amount determination unit 13. The received light amount determination unit 13 receives the amplification If the received light signal value is smaller than the set value, it is determined that the infrared ray is shielded before the light reception, and the light shielding signal is transmitted to the light shielding time comparing unit 14.

The light-shielding time comparator 14 sets and stores the light-shielding time in advance in order to determine whether the light-shielding light is blocked, counts the time at which the light-shielding progresses, and outputs an alarm signal to the alarm receiving and generating device 15 And transmits a specific alarm.

FIG. 2 is a flow chart illustrating a control process for sensing a light shielding of an RX module of a conventional infrared ray sensor and issuing an alarm. In the RX module 11, a received light reception signal value is calculated (S1) If the calculated value is less than the set value (S3), it is determined that the infrared signal irradiated by the TX module is shielded.

Therefore, when the infrared ray signal is shielded, the time is counted (S4) and the calculated light-shielding time is compared with the set time (S5). If the light-shielding time is longer than the set time, the surveillance region is blocked And issues an alarm (S6).

If the conventional infrared ray detector as described above infiltrates within a shorter time than the previously set light blocking time, that is, at a high speed, the RX module 11 may have a loophole that can not detect the shade.

In addition, in the conventional infrared ray detector, when the sensitivity of the TX module or the RX module is deteriorated due to the abnormality or the damage, the administrator checks the operation state of the infrared ray detector frequently because of a large security hole. However, In addition, it is installed on a high untouched place, and the reception voltage is measured by peeling off the cover of the infrared sensor on the receiving side, so that the infrared sensor is checked for an abnormality. Therefore, this operation is very troublesome and inconvenient.

The main reason for the decrease in the sensitivity of infrared light sensor is due to aging due to the elapse of time after installation of the sensor, due to environment such as strong winds or typhoons, fixation state relaxation, external shock, seasonal temperature change or diary change, It is caused by various reasons such as sensor position change during assembly.

Most of the infrared sensor's sensing sensitivity check is done by connecting the dedicated tester to the photoelectric conversion part of the light receiving signal to measure the receiving voltage. However, even if the infrared sensor is broken or the sensing sensitivity is low, The unmanned surveillance system is operated, which may cause security holes.

Particularly, the conventional infrared ray detector is alarmed even when the infrared ray signal is cut off due to falling leaves or shaking tree branches, so that an alarm signal which is not useful frequently causes a serious deterioration of the reliability of the infrared ray detector.

In order to solve such a problem, the inventor of the present invention comprehensively checks whether or not the infrared signal is detected and whether or not the object shape is detected in the image information photographed by the receiving section (RX module) of the infrared ray detector in parallel with the detection of the light- The present invention has been applied to a patent application No. 10-2014-0105046 filed with the applicant of the present invention.

However, the above-mentioned Patent Application No. 10-2014-0105046 has a distinct problem in that the intrusion path of an intruder or an escapee can not be clearly confirmed. In other words, the information determined based on whether the infrared sensor and the infrared signal are detected can only confirm infiltration. The information determined is whether the intruder intrudes from the outside of the security facility to the inside or escapes from the inside of the security facility to the outside There is a disadvantage in that it can not be clearly confirmed whether or not the situation is such a situation.

As described above, the present invention has developed an infrared ray sensor capable of further improving the reliability of the infrared ray detector disclosed in the above-mentioned Japanese Patent Application No. 10-2014-0105046, and has achieved remarkable results, I would like to propose.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a surveillance system for a surveillance system, which is capable of detecting whether or not an infrared signal is detected in an image information photographed by a camera module when sensing an infrared signal installed in a surveillance region, It is possible to improve the reliability of the infrared detector and the efficiency of the management of the security facilities, and to grasp the intrusion location and the infiltration and escape route accurately, The present invention provides an infrared sensor using an image, an operation method thereof, and an integrated management system for security facilities using the infrared sensor, which can easily check an abnormality of an infrared sensor without unnecessary field inspection.

Another object of the present invention is to replace the conventional infrared receiving module with a camera image to reduce the complexity and production cost of the device and to integrate the infrared detectors installed in a wide area to construct a security facility management system, At the same time, when the infrared signal is shielded, the infrared module detects the infrared signal from the image of the surveillance area installed toward the TX module and transmits the information to the administrator of the remote site through the communication module, (Combined) to manage the security facilities.

When the analysis signal is received from the image analysis module by the detection signal processing module and an image detection signal such as a wavelength detection signal and a shape detection signal is received, the alarm receiving and generating device stores the alarm notification and corresponding information, And transmits a wavelength detection signal value and a shape detection signal to the integrated management device. When the undetected signal of the video signal is received by the image analysis module, And transmitting the image information of 10 seconds before / after issuing the false alarm.

The detection signal processing unit of the present invention analyzes an image sensed by the image sensor, and when the output value of the infrared detection signal is equal to or lower than the set value and there is a shape detection signal, the alarm signal and the wavelength detection signal value are also output And transmits and stores the image information of a predetermined time, preferably 10 seconds before / after 10 seconds, to the administrator server, the monitor, and the alarm reception and notification device through the communication module. On the contrary, the infrared detection signal is received as a normal value by the image analysis module And if there is a shape detection signal, it can be realized by performing false alarm processing and transmitting false alarm data to the integrated management device. The false alarm data at this time includes a wavelength detection signal value, a shape detection signal, and image information.

In the present invention, when the TX module and the infrared ray receiving modules are installed in the vertical direction on both sides of the surveillance area, image information can be obtained by specifying the orientation angle of the camera module and the infiltration height of the intruder can be determined When the TX module and the infrared receiving modules are installed in the left and right direction on both sides of the surveillance area, it is possible to accurately judge whether the infiltration from the outside to the security facility or the escape from the inside to the outside through the information obtained by the sensing .

If the light receiving signal is smaller than the set value, the controller sends a signal for requesting the sensor sensor check, so that the manager can directly check whether the infrared sensor is abnormal or not.

Further, according to the present invention, whether or not an intruder is intruded can be accurately discriminated even if an abnormality or a failure occurs in a single infrared sensor when determining whether intrusion occurs by analyzing the existence of an infrared signal and the shape information on an image in a surveillance region. The reliability of the information can be drastically improved and the integrated management system of security facilities can be reliably constructed by connecting the infrared detector and the manager side integrated management device through the communication module.

Therefore, the administrator has the convenience of checking the TX module installed in a wide area and checking it at the remote site without checking it.

The present invention can also be applied to a fire monitoring application using infrared rays.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of an infrared ray detector using an image according to the present invention will be described in detail with reference to the accompanying drawings.

3A and 3B are a front view and a plan view illustrating a first embodiment of the principle of operation of an infrared sensor using an image according to the present invention, FIG. 4A is a block diagram illustrating a main configuration of an infrared ray detector using an image according to the present invention, and FIG. 4A is a block diagram illustrating the operation of the infrared ray detector using TX It is determined whether or not intrusion intrudes on the infrared (infrared) signal and shape information detected in the image (image) information sensed by the image sensor by the image sensor, and the alarm is invented according to the discrimination .

3A and 3B, the camera module 120 including the image sensor, which will be described later, faces the TX module 100 installed on both sides of the surveillance area, And may be installed on both sides of the surveillance area.

More preferably, the camera module 120 may be installed on both sides of the surveillance area in the vertical direction in which the infrared ray detector is installed. More preferably, The module 100 may be installed on both sides of the surveillance area so as to be spaced apart from each other by a predetermined distance in the horizontal direction and correspondingly the camera module 120 may be installed on both sides of the surveillance area as described above.

The TX module 100 installed on both sides of the surveillance area and the camera module 120 installed toward the TX module 100 are all the same in configuration so that any one of the infrared detectors and the camera module 120 Lt; / RTI >

4A, the infrared ray receiving module 110 includes an infrared ray signal transmitted from the TX module 100, a narrow angle lens 121, an image sensing unit 122, and a sensing area setting unit 123 An image analysis module 124 for analyzing the image information photographed by the camera module 120 and analyzing whether the infrared wavelength and the shape information are detected in the image, to the detection signal processor 130, And a detection signal processing unit 130 for discriminating an appropriate alarm signal and a false alarm signal in correspondence with the shape information signal and transmitting it to the alarm receiving and signaling apparatus 140. [

The coarse lens 121 of the camera module 120 described above is designed to minimize the sensing area of the image by the image sensor 122 to improve the analysis speed and resolution in image analysis to improve infrared wavelength detection and shape recognition.

The image sensing range can be adjusted by the sensing area setting unit 123 for the image captured by the narrow- An example of employing the sensing area setting unit 123 may employ a fixed manual iris method for the narrow lens 121. [

The image sensor 122 is installed in the camera module 120 and senses an infrared signal of the TX module 100 as an image and updates the image storage device 124a of the image analysis module 124 by a predetermined amount of time As shown in FIG.

The image analysis module 124 analyzes an image (image) stored in the image storage device 124a and transmits an analysis signal (presence / absence of infrared ray detection: ON = 1, OFF = 0) to the image processing unit.

As a preferred embodiment according to the image analysis, a technology capable of detecting the presence or absence of the infrared signal in the image information sensed by the image sensor 122 can be adopted without any difficulty.

A preferred example of the image analysis employed in the present invention is as follows.

In general, an infrared ray detector uses an infrared LED having a near infrared ray signal band having a center wavelength of 850 to 880 nm. The infrared ray LED has a spectral distribution characteristic ranging from about 700 nm to about 1 탆 wavelength band centering around 850 to 880 nm. The red light of the infrared LED for transmission on the transmitter side is visible to the naked eye, so that operation confirmation and adjustment are easy.

Since the visible light visible to the human eye is in the wavelength range of 350 to 740 nm, the light emitting state of the infrared LED is slightly bright red when viewed by the naked eye, but appears very bright on the image sensor side.

This is because the sensitivity characteristic of the image sensor in the near infrared region is more sensitive than that of the human eye. Therefore, in the present invention, the light emitting state of the infrared LED is enlarged by the image sensor, By comparing the video level changes in real time and comparing them with each other in real time, it is possible to significantly reduce the false alarm rate due to environmental changes.

In more detail, since the illuminance of the infrared LED in the daytime is bright in the surrounding illuminance, the image level is lower on the screen than in the nighttime. Since this is caused by the operation of the automatic iris of the image sensor, the present invention adopts a fixed iris type and an electronic shutter type instead of an automatic iris, since the image level value is kept constant as long as the brightness state is maintained constant. Therefore, if the value of the fixed iris is adjusted in a dark state at night, and the image portion in which the infrared LED emits light is extracted and the brightness value of the image level is read to convert the inverse multiple of the shutter time value, And the change in the image level is caused by the influence of the diary, ie, snow, rain, fog, leaves blowing in the wind, and glaze on the winter cover.

The infrared beam transmitted between the TX module and the infrared receiver module must be interrupted for more than a certain time in any case to generate an intrusion alarm. Likewise, the image level value of the image sensor is recognized as an intruding state only when it is '0' for a predetermined time or more. Assuming that the '0' value of the infrared ray beam and the image level are simultaneously matched and the exception of the infrared beam, assume that the TX module is faulty. If the level of the infrared wavelength is small or '0' , And all other alarm conditions are treated as false alarms.

When the false alarm is generated, the detection signal processor 130 transmits the image level value for receiving all data related thereto, that is, the infrared transmission signal, to the manager server so that the cause of the false alarm can be revealed.

The manager server includes a storage medium (memory, not shown) and a recording medium (program, not shown). The storage medium of the manager server is installed in the manager server in a number corresponding to the number of installed infrared receiving modules 110, and the information transmitted from the plurality of infrared receiving modules 110 is independently stored in the storage medium, Lt; / RTI >

The image of the infrared transmitting LED taken by the image sensor should be picked up as large and clear as possible so that the deviation of the calculation value of the image level is normally narrowed, and the background illuminance should be dark. The background of the infrared LED is the cover of the infrared detector. The cover is made of polycarbonate material with a dark red color so that the infrared beam can pass through. It is not necessary to darken the background separately. However, the size of the infrared LED If too little is displayed on the screen because it is very small, the amount of computation of the image level is also reduced because there are few portions that are brightly displayed even in the image processing, so that the deviation may become large.

For this purpose, it is necessary to use a narrow-angle lens and make a zoom magnification as large as possible. In the present invention, a lens having a focal distance of 100 mm or more may be required for a maximum installation distance of 100 m, and a sensing area setting unit 123 , See FIG. 4A), an image range to be calculated in inverse proportion to the number of pixels of the image sensor is suitably set, and the desired result can be achieved even when the image range is 50 mm or less.

That is, when a 100-mm lens and a 1.2-million-pixel image sensor are used when using a 300-megapixel image sensor 122 (see FIG. 4A), a 25-mm lens can be used in inverse proportion.

4A, the detection signal processing unit 130 receives the presence or absence of light transmission and shielding signals (light transmission = 0, light shielding = 1) transmitted by the camera module 120, When a new image signal (object shape) is sensed by the image sensor 122 after recognizing the received image signal as a background image at a normal time and controlled by the programmed control logic, whether or not the infrared image signal is received by the image information The shape detection alarm signal and the image information are immediately transmitted to the security facility integrated management system 200 through the communication modules 210A and 210B.

At this time, the detection signal processing unit 130 transmits the image information stored in the image storage device 124a to the image information before and after the alarm signal transmission, preferably, before and after the alarm signal transmission Sec. ≪ / RTI >

4B, the detection signal processing unit 130 may be installed in the infrared ray receiving module 110 or may be installed on the alarm receiving and signaling device 211 side. The detection signal processing unit 130 may include an image analysis module 124, (210A). In the former case, it can be prevented from being damaged when the infrared receiving module 110 is damaged, which is useful for building an integrated management system for multiple security facilities. In the latter case, it is useful for implementing an independent security facility management system.

When the detection signal processing unit 130 is installed in the infrared ray receiving module 110, the image storage device 124a is installed in the image analysis module 124, and the alarm reception and notification device (Contact signal) to one pair and twisted pair transmission method to the other pair using the two pairs of lines of the communication modules 210A and 210B, A communication method can be used.

The control processing of the alarm signal corresponding to the infrared ray detection signal output value in the image of the detection signal processing unit 130 will be described in more detail in the following control method of the infrared ray sensor.

Hereinafter, an implementation example of a security facility integrated management system using the infrared monitoring sensor shown in FIG. 4A will be described.

Referring to FIG. 4B, FIG. 4B is a block diagram illustrating a main configuration of a security facility integrated management system 200 using the infrared sensor shown in FIGS. 3A and 3B. The communication module 210A having a unique IP is connected to the infrared ray receiving module 110 and the camera installed in a specific location or space of the image analyzing module 124 and the infrared ray detecting signal and the shape detecting signal A monitor 230 for observing processing signals and image information transmitted from a remote place, and a communication (communication) for communicating with the facility-side communication module 210A Module 210B and an alarm reception and notification device 211. [

Therefore, the security facility integrated management system 200 based on the infrared ray receiving module 110 of the present invention can communicate information (data transmission) and control signals through the communication module 210A (210B) .

The infrared ray receiving module 110 may be installed on one or both sides of the surveillance area so as to face each other or may be installed adjacent to the surveillance area in the horizontal direction as shown in FIG. Can be implemented.

A pair of infrared detectors respectively installed in the directions facing each other detect the presence or absence of an infrared signal and presence or absence of an object shape (human body shape) in the aforementioned light-shielded image information, It is preferable to install at least two of them in the horizontal direction in the surveillance area. In this case, the information discriminated in accordance with the order of non-detection of the infrared signal included in the image information by the image sensor when detecting the infrared signal shading by the two infrared receiving modules is determined by the judgment of false alarm, It can be clearly discriminated whether or not it has escaped from the inside to the outside.

In the present invention, a plurality of TX modules may be installed on both sides of the surveillance area, and a single infrared receiver module may be installed so as to face the TX module to integrally detect whether the infrared signal is shielded through the single infrared receiver module . At this time, the infrared ray receiving module 110 may be installed in the vertical direction of the TX module 100 so that the directing angle of the infrared ray receiving module 110 is not overlapped with the directing angle of the opposite infrared ray receiving module 110.

In this case, since the sensing area of the image sensor of the infrared ray receiving module 110 is divided and sensed in the surveillance area, it is possible to obtain information that can clearly determine the infiltration height of the intruder according to the presence or absence of sensing by both image sensors .

Hereinafter, a method of operating an infrared ray detector using an image according to the present invention will be described with reference to FIG.

Referring to FIG. 5, FIG. 5 is a flow chart illustrating control processing of an infrared ray sensor using an image according to the present invention. As shown in FIGS. 3A to 3D, The sensing modules are installed in symmetry with respect to each other so that the sensing area of the image sensor is distinguished, that is, the sensing area is divided and sensed. The configuration of both the TX module 100 and the IR receiving module 110, Only the configuration of one side is explained.

First, the image information sensed through the image sensor of the camera module installed in the surveillance area is received (P1), and presence or absence of an object shape and presence of infrared (IR) wavelength are detected in the image information (P1).

 If only the shape of the human body is detected (P2) as a result of the determination as to whether or not the human body is present and whether or not the infrared (IR) wavelength is detected, a shape detection alarm is output. If the human body shape is detected and the IR wavelength is detected (P3) If the IR wavelength is more than the set value, the pre-stored environmental change factor (for example, the infrared wavelength level detected when the leaves, newspapers, plastic bags, small birds, balls, (A level value stored in advance) to determine a type of a false alarm corresponding to the level value of the sensed infrared wavelength, and outputting a false alarm signal corresponding to the detected false alarm type (P4).

For reference, the environmental change factor information is stored in advance in the memory by distinguishing the wavelength reception level value sensed by the infrared receiver module according to the size and movement speed of the various objects passing through the surveillance zone. (P4) in which the infrared wavelength reception level value sensed by the infrared ray receiving module is compared with the environmental change factor information (level value) stored in the memory when the temperature is small.

In other words, since the object passing through the surveillance area varies in the amount of received light depending on the size and the passing time, the infrared wavelength level appearing in various environmental change factors causing the difference is stored in the memory, And comparing the stored environmental change factor values to output a false alarm corresponding to the detected infrared wavelength when an infrared wavelength similar to the stored environmental change factor is detected.

When an infrared signal sensed by the image sensor of the image analysis module 124 is detected to be equal to or greater than a preset value, the output value is transmitted to the detection signal processing section and the output value when the light- 1 "to the detection signal processing unit. When the received signal is within the set range, the output value" 2 "is transmitted to the detection signal processing unit. At the same time, the output value above or below the specified value is transmitted to the environment change recognition definition program to determine the type of false alarm.

Also, when detecting the object shape, the output value "1" is transmitted to the detection signal unit, and in the opposite case, "0" is transmitted.

The control signal corresponding to the reception state of the output value of the image analysis module 124 is shown in Table 1 below.

division IR wavelength
Detection value Shape detection value process Situation 1 0 0 Alarm signal not transmitted (no intruder) Situation 2 One 0 False alarm signal transmission (attention signal), video information transmission Situation 3 0 One False alarm signal transmission (caution signal), video information transmission,
Shape detection signal transmission Situation 4 One One Alarm signal transmission, video information transmission Situation 5 2 False alarm transmission (sensor check signal transmission), video signal transmission Situation 6 2 False alarm transmission (sensor check signal transmission), video signal transmission

In Table 1, Situation 1 indicates that the infrared detector is in a normal operation state. Since the infrared signal is not detected in the image by the image analysis, it can be determined that there is no intruder.

In Table 1, Case 2 shows that the infrared detector is operating normally, but the result of detecting the infrared signal in the image as a result of the image analysis shows that the penetration attempt can not be predicted but only the detection area (surveillance area) The detection signal processing unit 130 transmits the false alarm signal to the administrator server 220 and stores the same.

In Table 1, the situation 3 is that the infrared signal detection signal is normal but only the object shape is detected. Therefore, it is possible that the infrared light beam is not blocked by leaves, insects, algae or the like or that the intruder walks above the height of the infrared beam Therefore, it is necessary to send the shape recognition false alarm signal and image information so that the manager directly checks the situation.

In the situation 4, since the infrared signal is not detected in the image and the object shape is detected as a result of the image analysis, the detection signal processing unit 130 detects the presence of the infiltrated air in the security facility integrated management system 200, , It transmits the emergency notification signal and transmits the image information at the same time so that the manager can directly go to the site or directly monitor the detailed situation through monitoring.

In the above Table 1, the states 5 and 6 indicate a sensor failure, a poor reception sensitivity, or a decrease in sensitivity due to a diary since the light receiving signal value is less than a predetermined value stored in advance. Therefore, the detection signal processing unit 130 Send an infrared sensor check request signal to the manager to check the infrared detector.

On the other hand, if it is determined that the comparison result of the environment change recognition program with the built-in time-to-signal value is a specific environment change, the administrator is notified of the type of false alarm.

In conclusion, situations 2 and 3 indicate that there is a problem somewhere in the management system of the security facilities, which means that the system check is needed after the situation is over.

As described above, the detection signal processing unit 130 synthesizes the received light signal output value, the reception state, the infrared ray signal output value in the image, and the shape detection signal to distinguish the false alarm signal, the sensor check request signal, the warning alarm signal, And transmits 10 seconds before and after images to the integrated management system 200 on the basis of the occurrence of a warning alarm and an emergency occurrence alarm, so that the manager can immediately cope with a situation in which a substantial response is required .

It is an illustrative example that the amount of image information transmission is set to 10 seconds before / after issuance of the alarm, but the time adjustment width should be set to be sufficiently large at the time of manufacture.

Therefore, the infrared ray receiving module 110 of the present invention can increase the reliability of the infrared ray detector by clearly informing the manager of the useful situation information that must be recognized in security facility management, Since the path and the infiltration position can be grasped accurately, the manager can respond to the situation immediately in case of an emergency, and it is also possible to check and confirm the abnormality of the infrared ray detector or whether there is a failure. Therefore, it is necessary to search each infrared ray detector And the reliability of the infrared ray detector is greatly improved.

According to the present invention, a plurality of TX modules are disposed on the upper part of a room, and a single infrared receiving module including a camera module corresponding to a plurality of TX modules is installed. When a fire occurs, The present invention can also be applied to a sensor capable of detecting the occurrence of a fire through a deviation of received light amount of an infrared signal or a shading sequence.
