For example, some CCTVs are monitored in the central management room of a building or an apartment complex, CCTVs managed by a security company, CCTVs installed and managed for public purposes such as crime prevention and waste disposal in police and government offices .

In a typical CCTV, images input from a plurality of CCTV cameras are automatically stored in an image storage device through an image capture device such as a screen divider or a DVR (Digital Video Recorder), and at the same time, activated on a monitor screen of a monitor . In this case, monitoring of a typical CCTV camera outputs images input from a plurality of CCTV cameras on a single monitor in a time division manner or a screen division manner. In some cases, the monitor arbitrarily manipulates one of the plurality of images output in time division or screen division manner to designate and monitor a certain CCTV camera.

Although there are many security / surveillance CCTVs, it is almost impossible for the surveillant to check the images of each camera as a whole due to the limit of the monitoring personnel. Therefore, Or as a passive countermeasure to secure evidence. For example, actively responding to crimes such as kidnapping of infants in an elevator, assault / violence in an elevator, sexual harassment / rape cases, off-site crime in a building or an apartment complex, crime on the street However, it is a reality that the crime is used as a means of securing evidence after the crime has occurred.

In addition, the CCTV is very large in size and has a stereotyped shape, so that an outsider can easily confirm whether it is installed or installed, or it can be moved or intruded only by a blind spot.

The object recognition unit 241 extracts the amount of movement change of the object from the real time image acquired for a preset time through the camera unit 110 of the safety module 100. [

Here, the object recognition unit 241 extracts an edge component from each frame of the real-time image, generates a predetermined closed region corresponding to the object using the extracted edge component, and regards the closed region as an amount of motion variation of the object.

At this time, the edge component of the object can be detected by the general edge detection algorithm such as the second derivative using the Laplacian operation. Since such an edge detection algorithm is obvious to those skilled in the art, a detailed description thereof will be omitted.

The voice recognition unit 242 extracts voice from among the sounds detected through the microphone unit 120 and recognizes the voice.

The data processing unit 243 compares the motion variation of the object extracted by the object recognition unit 241 with a predetermined minimum threshold value and a preset maximum threshold value larger than the minimum threshold value, And compares the frequency of the speech extracted by the speech recognition unit with a preset reference frequency to obtain a result of the comparison.

The abnormal state determination unit 244 determines that the object is in an abnormal state based on the result of the data processing unit 243 when the amount of motion change of the object is equal to or greater than the minimum threshold value or the extracted voice is equal to or greater than the reference frequency.

The mapping unit 246 converts the device information and the position information of each of the plurality of safety modules 100 displayed on the map display unit 220 into a database and then transmits the plurality of safety modules 100 selected together by the input unit 230 And maps them to a group.

In this case, the control module 240 maps the safety modules 100 selected by the input unit 230 to the same group, and at least one of the safety modules 100 belonging to the group is in an abnormal state The safety module 100 transmits the safety signal to the entire safety module 100 belonging to the group.

Device information Location information Abnormal condition Safety signal transmission group One S1 (2, 6) X X A 2 S2 (3, 4) O O B 3 S3 (4, 5) X O B 4 S4 (1, 3) X X A 5 S5 (2, 2) X O C 6 S6 (1, 1) X O C 7 S7 (4, 3) O O B 8 S8 (5, 2) X O B 9 S9 (3, 1) O O C

The operation of the control module 240 described above with reference to Table 1 will be described in detail as follows.

For example, as shown in Table 1, when the safety module 100 whose device information is 'S1' and 'S4' is designated as the group 'A' and the device information is designated as 'S2', 'S3', 'S7' The safety module 100 in which the safety module 100 of S8 is designated as the group B and the safety module 100 in which the device information is S5, S6 and S9 is designated as the group C, The three safety modules 100 in which the device information is 'S2', 'S7', and 'S9' are determined to be in an abnormal state as a result of discrimination of the abnormality state of each safety module 100 by the module 244 And the remaining six safety modules 100 are determined to be in an abnormal state.

At this time, a safety signal is transmitted to S2, S7, and S9 determined to be in an abnormal state. In addition, a safety module 100 having device information 'S2' and 'S7' S3 'and' S8 'which are the other safety modules 100 belonging to the group' B 'of the safety module 100 and the other safety modules 100 belonging to the group C of the safety module 100 whose device information is' S9' The safety signals S5 and S6 may be transmitted.

For example, when the amount of movement change of the object of the safety module 100 whose device information is 'S2' and 'S7' is equal to or greater than the minimum threshold value and less than the maximum threshold value, the entire safety module 100 belonging to the same group 'B' , The first safety signal is transmitted to the safety module 100 belonging to the same group 'C' when the amount of movement change of the object of the safety module 100 whose device information is 'S9' 2 Safety signal is transmitted.

5 is a flowchart of a control method using a safety module and a control server according to an embodiment of the present invention.

Hereinafter, a control method using the safety module and the control server according to the present invention will be described with reference to FIG. 5 and the above-described drawings.

First, at least one safety module 100 transmits data on device information and position information of each safety module 100 to the control server 200 (S100).

S1 ',' S2 ',' S3 ',' S4 ',' S5 ',' S6 ',' S7 ', and' S6 'are input from each of the nine safety modules 100, S8 'and S9', and position information '(2,6)', '3,4', '4,5', '1,3' ',' (1,1) ',' (4,3) ',' (5,2) 'and' (3,1) '.

In this case, the safety module 100 and the control server 200 can communicate through a predetermined network, and the network can be a local area network (LAN), a wireless local area network (WLAN) And may be one of a wide area network (WAN), an Internet, and a small area network (SAN), and the safety module 100 and the control server 200 may each be a Wi- Fi, Bluetooth, Zigbee, and the like, so that data can be transmitted and received by performing wireless communication therewith.

Next, based on the data received by the control server 200, the safety module 100 is displayed on a virtual map according to the respective position information (S200).

For example, as shown in FIG. 7, a total of nine safety modules 100, which have received the device information and the position information in step S100, are subjected to image sensing (image sensing) by the camera unit 110 A UI to be displayed in the original shape (S1 to S9) on a virtual map corresponding to the area can be generated and displayed on the display screen.

Next, the control server 200 selectively receives at least one safety module 100 on the displayed map (S300).

Next, the control server 200 designates the inputted safety module 100 as one group and maps the same to the group (S400).

In step S400, the control server 200 converts the device information and position information of each of the plurality of safety modules 100 displayed on the map into a database, and then transmits the input at least one safety module 100 It is designated as a group and mapped.

For example, referring to Table 1 and FIG. 7, the safety module 100 having the device information 'S1' and the device information 'S4' is selected and input, and the device is designated as the group 'A' S5 ',' S6 ', and' S9 ', the safety modules 100' S3 ',' S7 ', and' S8 ' (100) may be selected and input, and then the group 'C' may be mapped.

Next, the safety module 100 transmits the video and audio data obtained by the camera unit 110 and the microphone unit 120, respectively, to the control server 200 in real time (S500).

The safety module 100 includes a camera unit 110 for capturing a predetermined area and acquiring a real time image and a microphone unit 120 for sensing a sound generated in the vicinity of the camera unit 110 , The contents of each configuration have already been described in detail, and a detailed description thereof will be omitted.

Next, the control server 200 determines whether the safety module 100 is abnormal based on the information obtained through the camera unit 110 and the microphone unit 120 (S600).

Specifically, in operation S600, an object extraction step S610 of extracting a motion variation amount of the object from the real-time image acquired through the camera unit 110 for a predetermined time, (S620) for extracting and recognizing a voice, comparing the motion variation amount of the extracted object with a predetermined minimum threshold and a predetermined maximum threshold value larger than the minimum threshold value, A data processing step (S630) of obtaining a result according to a comparison with a predetermined reference frequency, and a data processing step (S630) of, if the motion variation amount of the object is equal to or more than the minimum threshold value or the extracted voice is equal to or more than the reference frequency And an abnormal state discrimination step (S640) for discriminating the safety module as an abnormal state.

In the object extracting step S610, an edge component is extracted from each frame of the real-time image, a predetermined closed region corresponding to the object is extracted using the extracted edge component, and the motion is regarded as a motion variation of the object.

At this time, the edge component of the object can be detected by the general edge detection algorithm such as the second derivative using the Laplacian operation. Since such an edge detection algorithm is obvious to those skilled in the art, a detailed description thereof will be omitted.

For example, referring to Table 1, when it is determined in the discrimination step S640 that each safety module 100 is in an abnormal state, it is determined that the three safety devices having the device information 'S2', 'S7' and 'S9' The module 100 may be determined to be in an abnormal state and the remaining six safety modules 100 may be determined to be in the abnormal state.

Next, when at least one safety module 100 belonging to the group is determined to be in an abnormal state by the control server 200, a predetermined safety signal is generated and transmitted to the entire safety module 100 belonging to the group (S700 ).

Specifically, if it is determined in step S700 that the amount of motion variation of the object is equal to or greater than a preset minimum threshold value and less than a predetermined maximum threshold value, which is greater than the minimum threshold value, (S710) for generating the second safety signal when the amount of movement change of the object is greater than or equal to the maximum threshold value, and generating a first safety signal or a second safety signal, To the entire safety module 100 included in the group to which the safety module 100 identified as the safety module 100 belongs.

For example, referring to FIG. 7 and Table 1, a safety signal is transmitted to S2, S7, and S9 determined to be in an abnormal state, and the device information is S2, S3 'and' S8 'which are the other safety modules 100 belonging to the group' B ', which is the group of the safety modules 100' S7 'and' S7 ', and' The safety signal may also be transmitted to the other safety modules 100 'S5' and 'S6' belonging to C '.

For example, when the amount of movement change of the object of the safety module 100 whose device information is 'S2' and 'S7' is equal to or greater than the minimum threshold value and less than the maximum threshold value, the entire safety module 100 belonging to the same group 'B' , The first safety signal is transmitted to the safety module 100 belonging to the same group 'C' when the amount of movement change of the object of the safety module 100 whose device information is 'S9' 2 Safety signal is transmitted.

Next, when the safety module 100 receives the safety signal, a safety zone is displayed by irradiating light of a specific shape toward the ground surface of the reference area spaced a predetermined distance from the camera unit 110, and the camera unit 110 (S800) so that the image sensing area of the camera 110 corresponds to the reference area.

In step S800, the position and direction of the light emitted by the safety module 100 may be different depending on the type of the safety signal received by the safety module 100. [

6A and 6B, if the first safety signal is received by the safety module 100, the center of the light output from the safety module 100 is transmitted from the camera unit 110 to the first distance d1 + L1 / 2), an annular safety zone having a diameter of 'L1' is displayed in the first reference area as the angle and direction are adjusted.
