[

2 and 3, the plurality of photographing ends 100 are arranged on the bridge 10 at predetermined intervals along the extended longitudinal direction of the bridge 10, They may be installed along both sides of the bridge 10 and may be installed only on one side of the bridge 10 if the sidewalk 11 is installed on only one side or the surveillance area of the sidewalk 11 installed on both sides of the bridge 11 can be photographed .

Here, each of the photographing ends 100 may be mounted on a mounting base 160 vertically disposed at a predetermined height for securing a visual field and protecting the equipment on a designated installation position. In the mounting base 160, 1 camera 110, a local control unit 130, a speaker 140, a second camera 150, an emergency bell 170, and a communication network 20 are mounted.

The first camera 110 photographs a part or the whole of the surveillance area for the sidewalk 11 extending along the side of the bridge 10 and recognizes the person located in the sidewalk 11 as a surveillance object and records the surveillance As the image acquiring means, a surveillance region is partitioned and installed according to a distance where the respective photographing ends 100 are spaced apart from each other in the entire range of the sidewalk 11 arranged in the bridge 10, and a pan, tilt and zoom function is provided Even if the current position of the recognized surveillance object changes, it is possible to obtain high quality image information by tracking. The acquired image information is transmitted to the local control unit 130 through the signal line such as wired or wireless, which is connected to the local control unit 130 in real time.

When a thermal camera equipped with a thermal sensing function is used as the first camera 110, a monitoring object can be recognized and tracked at night, and even if fog or sea dust occurs during the day, The object can be recognized and tracked.

The fall detection unit 120 is disposed outside the bridge 10 and is spaced apart at predetermined intervals along the extended longitudinal direction of the bridge 10 to detect a person falling down the bridge 10 from the sidewalk 11 The detecting means is provided outside the rail 12 provided at the outermost side of the bridge 10 to sense a person who is over the rail 12. The sensor 10 may be an ultrasonic sensor, It can be applied to a sensor means capable of sensing a specific object, in particular, a target object emitting heat.

Here, the falling detection unit 120 is spaced apart along the longitudinal direction of the bridge 10, and the detection range of each fall detection unit 120 is considered so that no detection gap occurs between the fall detection units 120 The distance between the photographing unit 100 and the falling detection unit 120 can be set to match 1: 1, and a single photographing unit 100 and a plurality of fall detection units 100, (120) may be installed in a one-to-many matching manner.

The fall detection unit 120 may be installed on the outside of the bridge 10, but preferably on a handrail 12 extending along the outside of the bridge 10. In this case, when the fall detection unit 120 is installed inside the railing 12 (on the side of the sidewalk 11), all the objects approaching the railing 12 can be recognized and easy to install and maintain, And recognizes the pedestrian passing near to the railing 12 when it is installed at the upper part of the railing 12 and recognizes the intent of the transmission when the elevator 12 is raised. It is possible to arrange the response system promptly, but there is a possibility of malfunction or erroneous operation due to the damage caused by the pedestrian or the curiosity of the pedestrian. As shown in the drawing, when installed on the outside of the handrail 12, it recognizes when the to-be-signed signs are raised on the handrail 12, thereby making it possible to determine the trust of the trust, However, it is difficult to install and maintain, and precise setting is limited when setting the device, which may cause a decrease in the detection rate. Therefore, it is preferable that the fall detection unit 120 is mounted at an appropriate position in consideration of the surrounding environment of the bridge 10, such as the frequency of the pedestrian, malfunction, possibility of misidentification, ease of maintenance, and the like.

In addition, it is preferable that the resolution is determined in consideration of the size of a person so that the detection of a fall of a false object such as a bird or a trash is filtered. As shown in FIG. 3, the fall detection information, To the local control unit 130 through the signal line L interconnected with the local control unit 130.

The local control unit 130 receives the bridge image information photographed by the first camera 110 and the fall detection information detected by the fall detection unit 120 and transmits the received fall detection information through the communication network 20, So that a waterproof and dustproof function can be realized.

In addition, the protective case may include a power supply unit for supplying driving power to each component together with the local control unit 130, and an amplifier for transmitting a high-power sound signal to the speaker 140.

The main server 200 collects and stores the bridge image information and the fall detection information transmitted from each photographing terminal 100 through the communication network 20 and analyzes the image information of each bridge image, If the fall detection information is received from an arbitrary photographing terminal 100 or if it is determined that an arbitrary monitored object has fallen through image analysis, And transmits the generated event information to the predetermined institution institution terminal 300 through the communication network 20.

Herein, the transmission occurrence event information is transmitted to the related authority terminal 300 and is information about contents related to the investment trust so that the related person in charge can recognize the information. The image information, the fall time, and the fall detection information.

In addition, the forbidden organ terminal 300 may include a communication terminal such as a PC disposed in a related institution such as a police station, an earthquake zone, a rescue team, and a disaster headquarters situation room capable of sanitizing a trustee of a trustee, And may be a mobile communication terminal such as a smart phone so that the portable or resident personnel of each relevant institution can carry it.

In addition, when the main server 200 analyzes the received bridge image information and detects a fall of the monitored object, as shown in FIG. 4, If the shape of the surveillance object being tracked in an arbitrary image frame disappears, the surveillance object is judged to have fallen to the lower part of the bridge.

Meanwhile, the bridge safety accident management system according to the preferred embodiment of the present invention is capable of continuously extracting the location information of the trustees located on the water surface and transferring the information to the related institution terminal 300 in real time To this end, the photographing terminal 100 photographs a part or the whole of the surveillance region for the water below the bridge 10, and uses the pan, til, and zoom functions to detect a person located on the water surface as a surveillance object The local controller 130 receives the sleep image information transmitted from the second camera 150 and transmits the sleep image information to the main server 200 through the communication network 20 send. The main server 200 receiving the sleeping image information collects and stores the sleeping image information transmitted from the local control unit 130 of each shooting end 100 and analyzes each sleeping image information to perform a recognized monitoring Extracts location information of the object located on the water surface, and transmits the extracted location information to the for-profit institution terminal 300 through the communication network 20.

Here, when the main server 200 collects and stores the image information and then analyzes and analyzes the image information, the main server 200 recognizes and recognizes the monitored objects by detecting the backlight of the sun, An image analysis solution is constructed to filter out the object of misunderstanding due to the surrounding or seasonal changes such as the increase and decrease of the shadow length according to the change, the headlight of the passing vehicle, and the fog .

In extracting the position information of the recognized surveillance object using the sleeping image information photographed from the second camera 150 of each photographing end 100, The camera 150 measures the position information of each photographing end 100 and the direction of the monitoring object from each photographing end 100 through the sleeping image information of the surveillance object, The position information of the corresponding surveillance object can be extracted.

In the meantime, each photographing end 100 stores installation position information on the bridge 10, and stores installation position information of the photographing end in each image information and detection information transmitted to the main server 200 The main server 200 controls the photographing operation of the second camera 150 installed at each of the photographing ends 100a to 100e as shown in FIG. When the falling detection information of the falling detection unit 120c is received or it is determined that an arbitrary monitored object has fallen through the image analysis of the bridge image information transmitted from the shooting end 100c, The second camera 150 provided in each of the photographing ends 100a to 100e is controlled to perform photographing driving with the center of the water surface position A corresponding to the position where the photographing end 100c is installed can do. Here, it is illustrated that the monitoring object (*) is recognized and tracked only by the second cameras 150a and 150f provided at the two shooting ends 1001 and 100f located at both ends of the bridge 10 100b, 100c, 100d, 100d, 100d, 100d, 100d, 100d, 100d, 100d, 100d, 100d, 100d, 100d, The second camera 150 may be used.

In this way, the lower local localized sleeping position (A) corresponding to the corresponding photographing end 100c, which is not the entire range of the water surface below the bridge 10, is detected as the surveillance region, It is possible to maximize the recognition speed and to solve the problem that the surveillance object whose position has been changed by the current can not be recognized while recognizing the surveillance object that has fallen down.

Herein, the main server 200 stores information on the water flow direction and the water flow rate under which the water below the bridge 10 is moved, estimates the moving path of the dropped monitoring object using the current water flow direction and flow velocity information The position (A) of the surveillance area for recognizing and tracking the surveillance object can be adjusted in detail.

In the meantime, in the bridge safety accident management system according to the preferred embodiment of the present invention, it is possible to detect a to-be- A speaker 140 for outputting sound may be installed on the mounting base 160 of the photographing terminal 100 and the speaker 140 may be provided on the mounting base 160 of the photographing terminal 100. For example, The main server 200 analyzes the bridge image information received from each photographing end 100 to detect a behavior pattern of each monitoring object and compares the behavior pattern reference data with the behavior pattern reference data based on the previously stored notification signs, If it is judged, it generates a communication signing event, transmits the generated communication signing event information to the related authority terminal 300 through the communication network 20, Genealogical broadcast source is controlled to be output through the speaker 140.

Here, the behavior pattern reference data based on the transmission indication is data obtained by digitizing an average pattern of behaviors that are performed by a normal transporter prior to transmission, and may be used to look at a distant place from a position on the bridge 10, Or a reference pattern for an action pattern such as getting on a railing or the like. Accordingly, when the main server 200 compares the behavior pattern reference data with the behavior patterns of the respective monitoring objects and matches the behavior pattern reference data with a predetermined value or more, the main server 200 determines that the monitoring objects indicate the signing signs, .

In addition, the transmission symptom event is information that is transmitted to the related institution terminal 300 so that the relevant person in charge can perceive the information related to the funding signal. The information includes the bridge image information before and after a certain time point Time, and the like.

In addition, the main server 200 controls the speaker 140 to output a voice signal input through a microphone (not shown) provided in the related institution terminal 300, The manager can check the transmitted bridge image information and if the behavior of the child is misunderstood as a traffic sign, the warning broadcast is outputted to the person who misunderstands the mistake behavior It may be sanctioned.

In this way, since the pre-stored system broadcasting sound source is output through the speaker 140 according to the generation of the transmission syndrome event, the system can minimize the possibility of the transmission, so that the transmission of the system can be minimized Can be delayed.

2 and 3, an emergency bell 170 and a communication terminal 180 for outputting an emergency signal may further be installed in the photographing terminal 100. The communication terminal 180 may be installed on the side of the bridge 10, The emergency signal is output by the third party when the third party who is moving the mobile terminal 11 recognizes the trusting party or the trusting signer and outputs the emergency signal. Is transmitted to the main server 200 via the local control unit 130 and is transmitted to the related institution terminal 300 as in the case of FIG. Accordingly, the administrator who has confirmed the emergency signal identifies the bridge image information photographed and transmitted from the photographing end 100 using the position information of the photographing end 100 provided with the emergency bell 170 outputting the emergency signal You can visually confirm the situation of the site so that immediate action can be taken.

In addition, the communication terminal 180 is a communication device that is connected to a professional counselor who can consult with a trustee, such as 'telephone of life', through a communication network and can communicate with a counselor. Here, the communication terminal 180 may establish a communication network capable of performing voice communication with the person in charge of the relevant organization in addition to the agent.

On the other hand, in the case of bridges where roadways are usually arranged, illegal parking on bridges is prohibited in order to prevent safety accidents. There is a plan for immediate control of vehicles that are parked on the bridge, Is not provided.

Accordingly, in the bridge safety accident management system according to the preferred embodiment of the present invention, not only the prevention of safety accidents due to the detection of the trustee or the trustee of the trustee, but also the detection of the illegally parked vehicle 30 on the bridge 10, 30, or by transmitting the occurrence information of the parking space vehicle to the relevant authority so that immediate measures can be taken by the person in charge.

To this end, a third camera having a surveillance area disposed on the bridge 10 is additionally installed in each photographing end 100, or a surveillance area of the first camera 110 is installed on the sidewalk 11 To the adjoining roadway 13, it is possible to detect the vehicle 30 which has been staggered for a predetermined time or more in each surveillance region. When the car 30 having been parked is detected, the main server 200 generates a parking lot occurrence event and transmits the generated parking lot occurrence event information to the terminal device of the police station or the regulatory agency through the communication network 20 A warning message on the bridge 10 by the vehicle 30 can be prevented by outputting a warning broadcast by the person in charge via the speaker 140 or performing an immediate action by dispatching personnel to the scene.

Meanwhile, the related authority terminal 300 transmits the image information photographed by the first camera 110 and the second camera 150 included in the transmission symptom event information and the transmission occurrence event information transmitted from the main server 200, The related institution terminal 300 displays the real-time image currently being photographed on the screen window and displays the real-time image on the screen window when the corresponding event occurs (For example, 10 to 60 seconds before the occurrence of the situation), the image of the captured image is displayed at the same time, And it is possible to determine whether or not it is dispatched according to the confirmation result, Minimization of field movements is possible.

In addition, when displaying the image information photographed by the first camera 110 and the second camera 150 on the screen window, the terminal 300 may include a plurality of photographing units It is preferable to divide the screen area into a plurality of screens and display different image information simultaneously as shown in FIGS. 7 and 8 so that the image information transmitted from the mobile terminal 100 can be collectively monitored.
