DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

1 is a schematic block diagram of a video surveillance system according to an embodiment of the present invention.

Referring to FIG. 1, the video surveillance system 100 according to an embodiment of the present invention may include an image monitoring unit 110 and a central control unit 120.

The video surveillance unit 110 may be disposed at a predetermined interval in the designated surveillance area, and may be spaced apart from the bridge overhead structures along the guided walk of the pedestrian. In particular, it is preferable that the video surveillance unit 110 is installed adjacent to a bridge rail (not shown) installed on the delivery side of the bridge so as not to interfere with the pedestrian.

Meanwhile, the video surveillance unit 110 may include a video surveillance unit 110 (hereinafter, referred to as " surveillance unit ") that is located in a designated surveillance area so as to prevent a shaded area covered by structures such as a solar cell panel And a predetermined interval is formed therebetween.

The video surveillance unit 110 is arranged to be spaced apart at predetermined intervals so that the designated surveillance regions are overlapped with each other by a predetermined interval so that they cross each other by various cameras, It is possible to monitor the object, thereby detecting the object moving along the guide of the bridge without generating a blind spot, acquiring the image of the sensed object and the sensed coordinate value, and transmitting it to the central control unit 120.

The central control unit 120 is disposed within the control center and may be connected to the video monitoring unit 110 through a wireless network. For example, the central control unit 120 may be connected to the video monitoring unit 110 through a wireless mesh network.

The central control unit 120 may receive the image and coordinate values of the object detected from the video monitoring unit 110 through the wireless mesh network.

Meanwhile, the central control unit 120 may store the behavior pattern of the attacking suicide.

For example, the action pattern of the shooter who is stored in the central control unit 120 may include an image pattern roaming for a predetermined time within a designated surveillance region, an image pattern stopped for a predetermined time or longer within the designated surveillance region, 120, an image pattern of an object moving in a forbidden direction, and an image pattern of an object moving in a direction opposite to a predetermined path direction. Meanwhile, in order to prevent the occurrence of fire in the designated surveillance area, an image pattern estimated as smoke and fire and an image pattern of a suspicious object in the designated surveillance area may be added as the action pattern of the attacking suicide.

When the image of the object detected from the image monitoring unit 110 and the sensed coordinate value are transmitted, the central control unit 120 compares the image delivered from the image monitoring unit 110 with the behavior pattern of the stored transmitted suicide The central control unit 120 determines that the detected object is a target of tracking detection when it is determined that the image of the sensed object transmitted from the image monitoring unit 110 and analyzed is in agreement with the behavior pattern of the pre- do.

When the central control unit 120 determines that the detected object is a tracking target, the central control unit 120 transmits a tracking detection signal to the video monitoring unit 110 to continuously operate the video monitoring unit 110 So that the tracking target can be tracked and observed.

At this time, the central control unit 120 not only can transmit an alarm to the tracking target object through the video monitoring unit 110, but also allows the central control unit 120 to monitor the object tracked by the video monitoring unit 110 If it is determined that the predetermined setting area is removed, the central control unit 120 automatically transmits the detection coordinate value of the object that is tracked together with the rescue signal to the rescue unit so that the quick rescue operation can be performed.

When the central control unit 120 determines that the object connected to the rescue unit via the wireless communication network and tracked and observed by the video surveillance unit 110 is out of the preset area set in the central control unit 120, So that it is possible to automatically and quickly transmit the detected coordinate values of the structure signal and the object.

Hereinafter, the configuration of the video monitoring unit 110 capable of acquiring images and sensed coordinate values of a designated surveillance region without occurrence of blind spots will be described in detail with reference to FIGS. 2 and 3. FIG.

FIG. 2 is a schematic block diagram for explaining a video surveillance unit according to an embodiment of the present invention, and FIG. 3 is a diagram illustrating an exemplary installation of a video surveillance unit according to an embodiment of the present invention.

As shown in FIG. 3, the video monitoring unit 110 may be installed in a plurality of pails 200 spaced apart from each other along the delivery of the bridge.

2 and 3, the video surveillance unit 110 according to an embodiment of the present invention includes an entrance detection camera 111a, a blind zone detection camera 111b, an object tracking camera 111c, (112).

The entry detection camera 111a may be arranged to detect an object crossing each other in a neighboring designated surveillance area.

On the other hand, the entrance detection camera 111a installed in the neighboring designated surveillance area is shielded by structures such as a solar panel installed on the railing of a bridge and the like, so that an image of the object is not captured by the entrance detection camera 111a And may be disposed at a predetermined distance so as not to generate a dead zone. That is, the entrance detection camera 111a installed in a designated surveillance area adjacent to each other is disposed so as to be able to photograph the lower parts of the structures crossing each other and spaced apart by a predetermined distance so as not to generate a video image blind spot by the structures .

A pair of entrance detection cameras 111a may be installed on the pawls 200 installed on the delivery side of the bridge, and the pair of entrance detection cameras 111a may detect a bi-directional image of the designated surveillance area, Direction, it is possible to detect an object entering and exiting the designated surveillance area, and transmit the sensed coordinate values of the sensed object to the central control unit 200.

For example, the entry detection camera 111a is a fixed type camera, and each camera can secure a monitoring range of up to 100 m, and can perform a fog correction, a shake correction function, and an SD / SDHC A box camera capable of supporting the memory card slot and separately attaching the lens to the housing can be used.

The blind zone detection camera 111b photographs a designated surveillance area located below the pair of entrance detection cameras 111a, which are blind spots that are not photographed by the pair of entrance detection cameras 111a, So that the image can be transmitted.

That is, when a pair of entry detection cameras 111a are installed in the pawl 200 so as to photograph the entering direction and the advancing direction of the object, 200 are not photographed by the pair of entrance detection cameras 111a, a blind spot of imaging is generated, so that an image of a blind spot in the lower part of the pole 200 A camera for detecting a blind zone 111b may be installed on the pole 200 so that a blind spot can be photographed.

For example, the blind spot camera 111b may be a fish-eye camera capable of photographing a minimum diameter of 20 m with respect to the pole 200 by a pair of entry detection cameras 111a Capturing a designated surveillance area under the pawl 200 that is not photographed, and transmitting the image to the central control unit 120.

When the object tracking camera 111c detects an object entering the surveillance area designated by the entry detection camera 111a, the object tracking camera 111c is operated by the central control unit 120 to transmit the object, which has entered the designated surveillance area, And transmits the sensed image of the sensed object and sensed coordinate values to the central control unit 120. [

For example, the object tracking camera 111c may be a rotatable camera that rotates in the upward, downward, left, and right directions and can track in all directions. Preferably, IR-integrated network PTZ camera with 30x optical zoom can be used.

In addition, the object tracking camera 111c includes an image stabilizer function capable of correcting the shake to obtain a clear image, a backlight correction function capable of improving the image quality of the image darkened by backlight, So that a clear image can be obtained.

When the object to be tracked is moved out of the designated surveillance area and is moved to a neighboring designated surveillance area, the object tracking camera 111c is linked to the object tracking camera 111c installed in a neighboring designated surveillance area, do.

In other words, the object tracking camera 111c allows the neighboring object tracking camera 111c to be operated by the central control unit 120 when the object to be tracked is out of the surveillance area, So that the moving objects can be tracked and detected in association with each other.

The sound generating unit 112 is connected to the central control unit 120 and receives an acoustic signal from the central control unit 120 to transmit an alarm, announcement, .

For example, the sound generating means 112 may be at least one speaker installed in the pawl 200.

The entrance detection camera 111a, the blind zone detection camera 111b, the object tracking camera 111c and the sound generating means 112 are arranged in the control center through the wireless mesh network via the network switch 118 And the central control unit 120 may be connected to the control unit.

Meanwhile, the video surveillance unit 110 according to an embodiment of the present invention may further include an emergency bell 113.

The emergency bell 113 is installed in the pole 200 disposed in the monitoring area designated to be connected to the central control unit 120 so that the emergency signal can be transmitted to the central control unit 120. In addition, the emergency bell 113 is capable of bidirectional communication with the central control unit 120, so that the caller can exchange communication with the control center.

The emergency bell 113 may also be connected to the central control unit 120 disposed within the control center via the wireless mesh network via the network switch 118.

In addition, the video monitoring unit 110 may further include an infrared ray detector 114.

The infrared ray detector 114 may be installed at a predetermined interval in a surveillance area where the plurality of video surveillance units 110 are installed.

For example, the infrared ray detectors 114 may be disposed at intervals of 50 m to 60 m along the bridge railing to be installed on the upper part of the bridge railing, or may be installed outside the bridge railing to prevent damage or malfunction by the pedestrian.

The infrared ray detector 114 finally senses whether the object is removed from the setting area and transmits the detected infrared ray to the central control unit 120 and outputs the position coordinate value of the object to the central control unit 120 ).

In other words, the infrared ray detector 114 detects a pedestrian when the pedestrian attempts to cross the bridge railing due to the installation of a plurality of pedestrians along the bridge railing, and sends a signal to the central control unit 120 that the pedestrian is off the set area And the position coordinates of the pedestrian outside the setting area are transmitted to the central control unit 120 so that a quick life-saving operation can be performed.

That is, the infrared sensor 114 confirms whether or not the pedestrian is in the bridge, and at the same time, transmits the precise transmission position of the pedestrian to the central control unit 120 so that it can perform a rapid life search operation, .

For example, when the infrared sensor 114 is provided with an alarm and an infrared sensor is activated, a primary alarm is generated and the infrared sensor 114 transmits an alarm generation signal to the central controller 120.

When the alarm generation signal is transmitted to the central control unit 120, the central control unit 120 controls the entrance detection camera 111a, the blind zone detection camera 111b, the object tracking camera 111c to analyze the image before and after the infrared sensor 114 is operated to determine whether the infrared sensor 114 has been operated by the actual pedestrian.

In the case of the infrared sensor 114, it may be operated by detecting an actual pedestrian. However, it can be operated even when a bird or the like passes through a bridge rail or seats on a bridge rail. Especially in summer, Or the like.

Therefore, when the infrared ray detector 114 is activated, the entrance detection camera 111a, the blind zone detection camera 111b, the object tracking camera 111a, and the object detection camera 111a installed in the surveillance area where the infrared ray detector 114 is operated by the central control unit 120 The infrared sensor 114 is operated by the bird, the geothermal heat, the exhaust heat, or the like by analyzing the image after the infrared sensor 114 transmitted from the infrared sensor 114c is operated and determining whether the infrared sensor 114 has been operated by the actual pedestrian Or whether it was operated by an actual pedestrian.

At this time, if it is determined by the central control unit 120 that the infrared sensor 114 has been operated by an animal such as a bird or the like that is not an actual pedestrian, or an external environment such as geothermal or exhaust heat, the central control unit 120 controls the infrared sensor 114 ). ≪ / RTI >

Alternatively, if it is determined by the central control unit 120 that the infrared sensor 114 has been operated due to an actual pedestrian, the central control unit 120 activates the sound generating means 112 to generate a secondary alarm , The object tracking camera 111c is operated to automatically track and photograph the pedestrian located in the surveillance area where the infrared ray detector 114 is operated and transmit the photographed image and the sensed position value to the central control unit 120. [

On the other hand, when the pedestrian is out of the area set by the infrared ray detector 114 and is transmitted outside the bridge railing, the infrared ray detector 114 informs the central controller 120 that the pedestrian is out of the set area, By transmitting position coordinate values out of the area, it is possible to carry out a quick life-saving operation.

The infrared ray detector 114 may be connected to the central control unit 120 through a wireless mesh network by being connected to the network switch 118 through a separate video server 117.

In addition, the image monitoring unit 110 may further include a thermal imaging camera 111d.

The thermal imager 111d senses the self heat of the object that has entered the designated surveillance area and can transmit the sensed image to the central control unit 120. [ Therefore, it is possible to easily grasp the object even if it is difficult to obtain a view with nighttime or bad weather.

Meanwhile, when the infrared camera 114d detects that the object, that is, the pedestrian is out of the set area, the infrared camera 114d is operated by the central control unit 120 to track and monitor the object, So that the position coordinates can be transmitted to the central control unit 120.

In other words, when the infrared camera 114d detects that the pedestrian is set off by the infrared sensor 114, the infrared camera 114c is operated by the central control unit 120 to track and monitor the transmitter moving along the stream, And the position coordinate values are transmitted to the central control unit 120, it is possible to track the location of the transmission center where the control center or the rescue team is moved, thereby making it possible to perform a quick and easy life search operation.

The video monitoring unit 110 may further include a drones 115 connected to the central control unit 120 via a wireless network.

When the operation signal of the thermal imaging camera 111d and the sensing position coordinates of the object are received by the central control unit 120 by the infrared sensor (not shown), the drones 115 are controlled by the central control unit 120 After moving to the sensing position coordinates of the received object, the image of the moving object and the sensing position coordinates can be transmitted to the central control unit while tracking and monitoring the object, so that the transferee is out of the sensing range of the infrared camera 111d The position of the trustee can be tracked to the end and the position coordinates of the trustee can be transmitted to the control center or the rescue team so that the survivor probability of the trustee can be further improved.

The video monitoring unit 110 may further include a mobile thermal imaging camera connected to the central control unit through a wireless network, although not shown in the figure.

In the case of the mobile thermal imaging camera, a rescue team is connected to a mobile terminal connected to a central control unit 120 having a rescue team so that when a rescue team is in operation at night, the rescue team board the rescue rescue boat and detect the body temperature of the rescue team. .

The video surveillance unit 110 further includes a shadow light 116 connected to the central control unit 120 and capable of displaying an image or a public interest phrase transmitted from the central control unit 120 in a designated surveillance area .

Here, the shadow illumination 116 is the same as or similar to a general shadow illumination applied to a street lamp or various signboards, and a detailed description of the shadow illumination 116 is omitted in the present invention.

In addition, the image monitoring unit 110 may further include a position indicator 119 attached to the pawl 200.

Each of the poles 200 on which the image monitoring unit 110 is installed is provided with a different number engraved on the position indicating plate 119, and the upward and downward directions are color-coded, Allow the driver to accurately identify the location of the trustee in the control center or rescue team.

The video surveillance system 100 according to an embodiment of the present invention includes a display unit 130 for displaying an image of an object photographed by the video surveillance unit 110 and transmitted to the central control unit 120, And the display unit 130 may be disposed in the control center in the same manner as the central control unit 120.

In addition, the video surveillance system 100 according to an embodiment of the present invention includes a storage 140 for storing an image of an object photographed by the video surveillance unit 110 and transmitted to the central control unit 120 and sensed coordinate values, And the storage 140 may also be disposed in the control center as with the central control unit 120. [

A video surveillance method using a video surveillance system according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG.

4 is a flowchart illustrating an image monitoring method using a video surveillance system according to an embodiment of the present invention.

Referring to FIGS. 1 to 4, first, it is determined whether an object is detected in the surveillance area designated by the central control unit 120 through an image photographed through the pair of entry detection cameras 111a (S110).

Here, the entrance detection camera 111a is disposed at a predetermined interval so as to be able to detect an object by intersecting with each other in a neighboring designated surveillance area which can be photographed by neighboring entrance detection cameras 111a, It is possible to capture an object entering a designated surveillance area by shooting a bi-directional image without a blind spot.

In addition, when the object is detected by the entry detection camera 111a, the entry detection camera 111a transmits the detected object image and the detected coordinate value to the central control unit 120. [

If it is determined by the central control unit 120 that an object is detected in the designated sensing area, the central control unit 120 determines whether the object sensed by the entrance sensing camera 111a is a sensing object (S120).

Here, the central control unit 120 compares and analyzes the image of the object photographed and transmitted by the entrance detection camera 111a with the behavior patterns of the trustees who are stored in advance, and determines whether or not the object is the object of detection .

For example, the action pattern of the committed suicide previously stored in the central control unit 120 may include an image pattern of an object roaming for a predetermined time within a designated surveillance area, an image pattern of an object estimated by smoke and fire, An image pattern of an object moving in a forbidden direction, an image pattern of an object moving in a direction opposite to a predetermined path direction, an image pattern of an object moving in a forbidden direction, Pattern. ≪ / RTI >

When the central controller 120 determines that the object sensed by the entrance sensing camera 111a is an object to be sensed, the central control unit 120 activates the object tracking camera 111c to control the entrance sensing camera 111a In addition, the object is tracked and detected through the object tracking camera 111c (S130).

In this case, not only the entry detection camera 111a and the object tracking camera 111c but also the dead zone detection camera 111b are operated to capture an image even in a rectangular area not captured by the entry detection camera 111a, 120).

At this time, the central control unit 120 may operate the sound generating means 112 to send an alarm, an announcement broadcast or a live broadcast to the object to be sensed.

When the infrared sensor operation signal is transmitted from the infrared sensor 114 to the central control unit 120, the central control unit 120 determines whether the infrared sensor 114 has been activated by the object determined to be actually sensed (S140).

On the other hand, if it is determined that the infrared sensor 114 has been operated by the object determined to be actually sensed by the central control unit 120, the image of the sensing object photographed by the object tracking camera 111c and the sensed position value are centered And transmitted to the control unit 120 (S150).

At this time, the central control unit 120 may activate the sound generating means 120 to generate a secondary alarm to the object to be sensed.

When a signal indicating that the object to be detected is out of the setting area and a position coordinate value are transmitted from the infrared ray detector 114 to the central controller 120, the central controller 120 controls the infrared camera 111d ) Is activated to track the object, and at the same time, the rescue signal and the image and sensing position coordinates of the object are transmitted (S160).

At this time, the central control unit 120 activates the thermal imaging camera 111d and simultaneously activates the drones 115 to move the drones 115 to the detected position coordinates of the received object, It is possible to track and detect even a person who is out of the detection area of the thermal imaging camera 111d by transmitting the image of the object and the sensing position coordinate value from the dragon 115 to the rescue unit, do.

In the video surveillance system and the video surveillance method using the video surveillance system according to an embodiment of the present invention as described above, there is no blind spot and the surveillance object is tracked, and at the same time, And the rescue team can be quickly dispatched to the correct position, so that it is possible to prevent suicide of the trust in the bridge in advance.

In addition, the video surveillance system and the video surveillance method using the video surveillance system according to an embodiment of the present invention can precisely distinguish and detect whether an object detected in a designated surveillance area is a target or not, Since rescue signals can be sent to rescue units, waste of rescue personnel and rescue costs due to erroneous rescue signals can be prevented.

In addition, the video surveillance system and the video surveillance method using the video surveillance system according to an embodiment of the present invention accurately detect the transmission position of the transmission person and transmit the transmission position to the rescue unit. In addition, the position of the transmission person moving along the stream after the transmission is also detected So that the rescue team can make the construction work faster and more accurately, which can significantly improve the rescue structure.
