Hereinafter, a traffic surveillance system for a surveillance camera according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of a traffic monitoring system of a surveillance camera according to the present invention, and FIG. 2 is a block diagram of a traffic monitor according to the present invention.

As shown in FIG. 1, the traffic surveillance system of a surveillance camera according to the present invention includes a surveillance server 200 connected to a plurality of surveillance cameras 100 to receive images; A traffic monitor (300) interposed between the plurality of surveillance cameras (100) and the control server (200) and monitoring the traffic of the video on a session - by - session basis; And an administrator terminal 400 connected to the traffic monitor 300 through a mobile communication network and further includes an image storage device 500 interposed between the plurality of surveillance cameras 100 and the traffic monitor 300 .

The traffic surveillance system of the surveillance camera according to the present invention is a surveillance surveillance system of the surveillance camera in which the traffic surveillance 300 is interposed between the surveillance camera 100 and the surveillance server 200, (Mornitoring) is the basic technical idea.

The surveillance camera 100 is an element for acquiring an external image, and may be installed on a telephone pole of a road, installed in various places such as a building or a parking lot to acquire an image of the place, and transmit the acquired image to the control server 200 do. The surveillance camera 100 may include a conventional analog CCTV camera, a recent digital IP camera, and the like.

The digital IP camera has a space for storing the acquired image, so a separate storage device is not necessary. However, the analog CCTV camera requires a separate storage device. Therefore, when the surveillance camera 100 includes an analog CCTV camera, a separate video storage device 500 is provided. In addition to the configuration including the IP camera, the video storage device 500 may be provided have.

The image storage device 500 is a component for receiving and storing images from each of the plurality of surveillance cameras 100. The DVR (Digital Video Recorder) and the NVR (Network Video Recorder) are typical examples. The DVR provides a function of converting an image (analog signal) received from the surveillance camera 100 into a digital signal in a storage space, compressing and storing the digital signal, and allowing a manager to instantaneously search the stored digital image. Type CCTV camera is connected, and a digital IP camera is connected to the NVR.

The control server 200 is a component that is connected to the video storage 500 and receives the video acquired by the surveillance camera 100. The video obtained by the surveillance camera 100 is transmitted to the control server 200, This image is displayed on the control server 200. The administrator can view the displayed screen and monitor the area where the surveillance camera 100 is installed or determine whether the surveillance camera 100 has failed.

The control server 200 forms a session with each of the surveillance cameras 100 and includes a video storage device 500. The control server 200 includes a session management server 100 and a video storage device 500, .

The session is divided into a video transmission session and a general session. The video transmission session is a session for transmitting images acquired by each surveillance camera 100, and a general session is a session between the control server 200 and the video storage 500 The session is a session in which a control signal and other signals are transmitted and received to and from a session.

FIG. 3 is a view for analyzing the traffic of an image transmitted from the surveillance camera on a session-by-session basis. In this case, two surveillance cameras 100 are connected to the control server 200 through the image storage device 500. In this case, three sessions are created as shown in FIG. 3. The two sessions are video transmission sessions in which the surveillance camera 100 transmits video through a connection session between the surveillance camera 100 and the control server 200, The remaining one session is a connection session between the video storage 500 and the control server 200 and is a general session.

The traffic monitor 300 is a component interposed between the surveillance camera 100 and the control server 200 and monitors the traffic of the video transmitted from the surveillance camera 100 to the control server 200 on a session-by-session basis. The traffic monitor 300 includes a failure determination unit 310 to monitor the traffic for each session to determine whether the failure has occurred. In addition, the traffic monitor 300 monitors the traffic for each session and stores the number of installed surveillance cameras 100 in the traffic monitor 300 to determine whether the surveillance camera 100 has failed, Is also stored in the traffic monitor (300).

The failure determination unit 310 determines that the traffic of the image for the predetermined time is normal if the number of the sessions is equal to or greater than the reference traffic (RT) and the number of the image transmission sessions, If the number of sessions having the traffic (RT) or more is smaller than the number of the video transmission sessions, it is determined that a failure has occurred.

At this time, the predetermined time is set to 1 minute, and the reference traffic (RT) can be set to 1 MB. That is, if the number of sessions having a traffic of 1 MB or more is equal to the number of video transmission sessions, it is determined that the number of sessions having a traffic of 1 MB or more is smaller than the number of video transmission sessions It is judged that a fault has occurred.

Since the video transmission session transmits an image, it has a certain amount of traffic (capacity). On the contrary, since a general session transmits a control signal and other signals, that is, a signal having a small capacity, it is possible to communicate with much less traffic than in the case of an image.

Therefore, the traffic (capacity) of a predetermined size is set as the reference traffic RT, the traffic received for each session for a predetermined time is measured, and the session over the reference traffic RT can be regarded as a steady-state video transmission session.

Therefore, it can be determined that the number of sessions that are equal to or greater than the reference traffic RT is equal to the number of the video transmission sessions. If the number of sessions that are equal to or greater than the reference traffic RT is smaller than the number of video transmission sessions, It can be judged that it has occurred.

For example, when three surveillance cameras 100 are installed, three video transmission sessions are created, and the video is transmitted through the video transmission session. At this time, the traffic monitor 300 measures traffic on a per-session basis. If the number of sessions with traffic of 1 MB / 1 minute or more is judged to be normal and the number of sessions with traffic of 1 MB / It can be determined that a failure has occurred in the surveillance camera 100 connected to the session in which the failure has occurred.

However, since the amount of information (image) to be transmitted is small, the traffic may be instantaneously reduced, and the traffic may be temporarily reduced due to a momentary error. Even in such a case, if the failure is judged to have occurred, the accuracy of the failure judgment becomes poor. In order to prevent this, when the number of sessions in which traffic of 1 MB or less is continuously transmitted three or four times in a minute is smaller than the number of surveillance cameras 100, that is, the number of video transmission sessions, It can be judged.

When the failure determination unit 310 determines that a failure has occurred, the failure signal transmission unit 320 generates a failure occurrence signal and transmits the failure occurrence signal to the administrator terminal 400 through the mobile communication network. Thus, the administrator can recognize that a failure has occurred have. The failure occurrence signal may include a port of a session, an IP address of the video storage device 500, or information on a place where the surveillance camera 100 is installed.

The administrator terminal 400 is an administrator terminal residing in the control center, and can be exemplified by a manager's mobile phone (smart phone), PDA, tablet computer, and the like. And a text message is used in a manner that a failure occurrence signal is transmitted to the administrator terminal 400 through the mobile communication network. In addition, a separate application may be installed in the administrator terminal 400, and may be transmitted through the installed application so that the administrator can recognize it.

As described above, the administrator can quickly recognize that the surveillance camera 100 among the plurality of surveillance cameras 100 has a failure via the administrator terminal 400. The administrator can take appropriate measures such as restoring the surveillance camera 100 after such recognition.

After the failure of the surveillance camera 100, it is necessary to check whether the recovery has been performed properly. The traffic monitor 300 further includes a recovery determination unit 330 and a recovery signal transmission unit 340, The determination unit 330 can confirm whether the surveillance camera 100 is properly recovered.

If the number of sessions in which the traffic of the video transmitted for a predetermined time is equal to or greater than the reference traffic RT is equal to the number of the video transmission sessions, the recovery determination unit 330 determines that the recovery is successful. If the recovery determination unit 330 determines that recovery has been performed, the recovery signal generation unit 330 generates a recovery signal and transmits the recovery signal to the administrator terminal 400.

For example, if the number of sessions in which 1 MB or less of traffic is continuously transmitted three or four times in a minute is equal to the number of video transmission sessions, that is, the number of surveillance cameras 100, it is determined that the surveillance camera 100 is properly recovered do. The failure determination unit 310 may replace the recovery determination function of the recovery determination unit 330.

If the recovery determination unit 330 determines that the recovery is successful, the recovery signal transmission unit 340 generates a recovery signal and transmits the recovery signal to the administrator terminal 400. When the failure determination unit 310 replaces the recovery determination function The failure signal transmitting unit 320 may replace the recovery signal transmission.
