The present invention relates to a video surveillance system of the outer fence by a logical division for logically partitioning and monitoring the outer fence,

In more detail,

CCTV cameras (surveillance cameras) for monitoring the outer fences are arranged at regular intervals to physically divide and set the areas that the surveillance cameras can monitor. Divide it into zones and partition it,

Each surveillance camera should monitor each logical partition sequentially while rotating / moving with a certain time difference within the assigned physical partition area, and if abnormal signs (abnormal movements) are found in a specific area during the monitoring operation. Immediately after alarming and temporarily stopping the movement / rotation of the surveillance camera in the logical area,

While monitoring the situation at the same time, recording the situation of the site and analyzing the movement of the site, if the abnormal movement is judged to be an intruder, the surveillance camera can be remotely controlled by following the movement by tracking the location manually or automatically. The present invention relates to a video surveillance system of an outer fence by logical division.

As the quality of life is improved, competition for science and technology is fierce, and security interest is gradually increasing, the importance of security on buildings is emphasized more.

In addition, with the development of science and technology, security technology is improving day by day.

Conventional security technology is mainly put a lot of security in the building. Therefore, security in a high-density building, such as an intelligent building, is implemented with a very high level of security technology.

In other words, the security management system in the building is equipped with a closed-circuit camera installed in the element to monitor and compensate for the blocking of the field of view by the infrared camera, and if an abnormality is found, analyze the image to determine the intruder's authenticity. High technology is being mobilized.

However, the security of the exterior of the building still uses the conventional security system as it is.

The following is an example of the use of the security system for most of the outskirts currently in operation.

First, with a simple city view (surveillance camera), a fixed part of the outer fence is fixed and concentrated shots are monitored and observed in the room.

Second, by applying a voltage to the outer fence to make the outsider's access impossible to block the access or when there is a contact with the outsider to detect and alarm.

Third, as the most important security measure, security guards usually take guards or patrols to monitor intrusions.

The reason why the security system for the outskirts is relatively low compared to the security system in the building is that the area of security to be secured is much larger than in the building.

Therefore, the application of the security system in the small area such as in the building to the fence outside the building requires a very high security facility cost, so the economic efficiency of installation and operation of the security facility is significantly reduced, and thus its use is avoided.

However, there is a weak point that the guard outside the building is relatively wider than inside the building, while the guard zone is relatively much more open than inside the building, so it is relatively easy to find outsiders' access and the inside of the building can be accessed by outsiders. It is characterized by a relatively long time.

Therefore, there is an advantage that the outsider's access can be easily found even if the monitoring is carried out at a certain time difference without fixed and intensive monitoring like inside the building.

In view of the above, the present invention has developed a system that enables security management in the same way as the inside of a building at a relatively low cost with a relatively low cost.

In other words, the present invention is to arrange the CCTV cameras (surveillance cameras) for monitoring the outer fence at regular intervals to physically set the area that each surveillance camera can monitor, and each of the surveillance cameras can monitor. Partition a station into multiple logical regions,

The surveillance cameras monitor each zone sequentially while rotating / moving the logical zone with a certain time difference, and if an abnormality sign (abnormal movement) is found in a specific logical zone during the monitoring, specially alarms it through the video output unit. At the same time, pause the rotation / movement of the surveillance camera in the logical area.

The central control unit monitors abnormal movements by remotely controlling the surveillance cameras, tracks the movements of the abnormal movements, intensively monitors the movements of the scene, and records (records) the current situation and analyzes the movements of the sites. As a result, if the abnormal movement is judged to be an intruder, it aims to alert it through the alarm means and to propagate it to the relevant organizations.

In addition, the indoor alarm unit 319a and the outdoor alarm unit 319b are divided into a warning light and a voice alarm unit (not shown) which visually alert this.

Referring to Figures 2 to 7 the operation of the present invention configured as described above is as follows.

Figure 2 is a block diagram of the outer fence monitoring system according to the logical division of the present invention, Figure 3 is a logical division partition diagram of the outer fence according to the present invention, Figure 4 shows a sequential monitoring procedure and allocation time of the logical partition zone 5 is a flowchart illustrating the outer fence monitoring by logical division, FIG. 6 is a flowchart for detecting abnormal symptoms, and FIG. 7 is a flowchart for manual operation.

As mentioned above, the outer fence 100 is physically divided so that a surveillance camera 210 for monitoring each physical partition A, B ... N is assigned.

In addition, the physical partition is divided into a plurality of logical zones, and the addresses (a1, a2, ..., b1, b2 ...) are given, and then the surveillance cameras monitoring the zones are logically divided at regular intervals. Will be monitored sequentially.

2 shows a state in which a part of the outer fence 100 is physically divided, and the symbols A, B, ..., N illustrated here represent the addresses of the physical partitions and these physical partitions One surveillance camera Ca, Cb, ... Cn is assigned to each.

3 illustrates a state in which the physical partition is logically divided again.

Here, a1, a2, ... an, b1, b2, ... bn denote the addresses of logical divisions, and these zones are monitored while the assigned surveillance camera 210 sequentially moves / rotates with a certain time difference. Will be performed.

The time difference is the most of the time to capture the moving situation of the object moving to the outer fence or moving in the outer fence in consideration of the separation distance between the surveillance camera 210 and the outer fence 100, the front clock, etc. It is set by calculating a long time, which is calculated by the operator according to the situation of the site.

In addition, the physical partitions (A, B, ... N) is the most perfect without the obstacles, such as one surveillance camera in consideration of the surveillance performance of the surveillance camera 210 and the presence of surrounding features or obstacles, etc. The extent to which surveillance can be performed is set, and logical division zones (a1, a2, ..., b1, b2 ...) are considered in consideration of the time difference and the shooting range of the rotation / movement of the surveillance camera. Each appropriate time is set for the situation at the site.

FIG. 4 illustrates a sequence and time arrangement in which the surveillance camera Ca rotates / moves and monitors the logical partitions a1 to a20 in the physical partition A. FIG. Here, the logical division is illustrated as 20, but depending on the situation of the site, it can be adjusted by changing the area to 36 76 or so.

The illustrated example shows that the monitoring camera 210 changes the monitoring operation in the order of monitoring for 2 seconds by changing the monitoring zone to a2 again after monitoring for 2 seconds in the logical zone a1. The surveillance camera continuously monitors for 2 seconds, changes to the next zone in order, and performs surveillance. After finishing zone a10, it changes the surveillance zone to a11 by changing the upper and lower angles. Then, repeat the same process from the area a1.

In the example, it can be seen that the time required to monitor all the monitoring zones A takes 40 seconds. This means that monitoring a logical area at 40-second intervals can capture the intruder's movement without losing sight. If the situation is less than 40 seconds, the time should be shortened as necessary.

In other words, here, the monitoring time of each logical zone is illustrated as 2 seconds. However, if the number of logical zones for monitoring decreases, the monitoring time may be long. On the contrary, when the number of logical zones for monitoring increases, an abnormal symptom is captured. It is necessary to shorten the monitoring time relatively to complete the process.

In addition, when the distance between the surveillance camera 210 and the outer fence 100 is shortened, the monitoring time should be further reduced or the number of logical monitoring zones should be reduced so as not to let go of the capture of moving objects. However, this is not fixed and the most appropriate method is selected and designated according to the situation of the site.

The image information captured by the surveillance camera 210 is received through the central wireless transmission and reception unit 230 and the antenna An together with the addresses a1, a2, ..., b1, b2 ... of the logical zone. It is transmitted to the unit 311, which is converted into an image signal through the image signal converting unit 312 and assigned to the image output unit 325 corresponding to the address from the central control unit 313, and then the monitor 321 is output. .

At the same time, the central control unit 313 analyzes the image.

The central control unit 313 outputs and contrasts previous image information stored in the memory 315 to determine whether the image is normal. If there is no change in the image, the central controller 313 considers that no abnormality is found and a new image. After the information is stored in the memory, the video signal is output through the monitor 321 of the designated video output unit 325.

If it is found that image information different from the conventionally input image information is input in the analysis process, the central control unit 313 considers this as an abnormal symptom and sends a command to temporarily stop the rotation / movement of the surveillance camera 210. At the same time, the video signal is output through the monitor 321 of the image output unit 325 and the alarm unit 324 at the bottom of the monitor 321 alerts that an abnormal symptom is visually and audibly detected.

When an abnormal alarm is issued, the operator of the situation room immediately operates the operation unit 314 to manually switch the movement of the surveillance camera 210 and confirms the abnormality, and then remotely operates the surveillance camera 210 to track the cause. Analyze

On the other hand, the central control unit 313 is an alarm is issued, even if a certain time elapses, if the situation room worker does not take any action immediately by operating the automatic location tracking program 317 automatically remotely control the surveillance camera 210 to schedule After tracking the movement of time, and taking surveillance shots for a predetermined time (for example, 40 seconds), the alarm is recorded in the recording unit 316 along with the image information, and then the automatic position tracking program 317 is stopped again. Return to surveillance.

While the automatic location tracking program 317 is driven, a red lamp (not shown) is turned on in the central control unit 313 to indicate that the automatic location tracking program is being driven.

However, the present invention is not a technical point in the development of a new image tracking method, but in the use of the image tracking method, so a detailed description of the automatic location tracking will be omitted here. In addition, it is sufficient to select an image tracking method for automatically tracking an image by selecting and using one of various image tracking techniques already filed and published.

In addition, the remote control of the surveillance camera 210 is transmitted to the central wireless transmission and reception unit 311 through the central control unit 313 is transmitted to the local control unit 220 through the local wireless transmission and reception unit 230 through the antenna (An). .

The local control unit 220 receiving the remote control signal performs an emergency control command in preference to other control commands. That is, the remote control is issued by the central control unit 313 regardless of whether it is manual control or automatic control, all of which are stored in the recording unit 316 and the memory 315 to be recorded.

On the other hand, when the situation room worker tracks the image by manual control and finds an abnormality (for example, when the movement is found to be an intruder), the situation room worker presses an alarm switch (not shown) on the operation unit 314 to enter and exit the alarm situation. On the other hand, it will be delivered to the relevant organization 500 by wired or wireless through the public communication network 400 to seek cooperation.

In addition, when the alarm is issued from the central control unit 313, the outdoor alarm unit 319b illuminates the lights 318 in the corresponding area of the outer fence 100, while the alarm siren sounds with the indoor alarm unit 319a and flashes the alarm lamp to make an emergency. Inform the inside and outside workers of the situation and issue a threat warning to the intruder.

In addition, if no abnormality is found as a result of manual position tracking, the situation room worker operates the normal return switch to return the device to the normal state and returns to the normal state.

According to the above process, it is possible to thoroughly perform the boundary of the wider outer fence at a lower cost. It will also enable more advanced and complete alarm systems.

According to the present invention as described above,

By logically dividing the outskirts of the fence, it is possible to perform surveillance tasks while tracking images.

1) It is possible to effectively monitor large areas at low cost, which can greatly reduce the cost of installing personnel and security facilities to carry out the expenses.

2) In carrying out the surveillance work, all situations are stored on the computer and the operator can reproduce and copy them as necessary, so that the responsibility for performing the monitoring work becomes clear, thus enabling reliable surveillance work.

3) In addition, the video surveillance service can be performed manually and automatically selectively, enabling the uninterrupted monitoring service by implementing the optimized system.

4) It is possible to program the surveillance service to provide an optimized system for the military, police, large factories, large apartment complexes, airports, ports and docks, oil storage complexes, and ammunition depots.
