Description

{A apparatus for watch / alarm an area / fence}

(Technical area to which the design belongs)

This system is to monitor the outside and outside of the special area where thorough facility monitoring and alarm system is required such as military units, security facilities, etc., and to alarm when there is an abnormal situation, CCTV for area monitoring, infrared camera for fence monitoring, The present invention relates to an area / fence monitoring and alarm system composed of an alarm device, a communication line, a central control device, and a monitoring system.

This proposal proposes a group of CCTV groups by grouping four CCTV surveillance modules each installed in a plurality of areas and integrating four CCTV modules into a single video / data / audio server. Connect the group to the CCTV optical relay using a LAN cable,

After constructing the fence monitoring system consisting of infrared cameras as the monitoring system of the main part and the part and connecting it to the optical relay device for fence monitoring,

By integrating the CCTV optical relay device and the fence monitoring optical relay device by linking them into one optical cable core and configured to be connected to the central control device and the monitoring system through the switch hub,

To simplify the overall configuration of the system to reduce the installation and maintenance costs of the system, to reduce the air required to install the system, and to significantly reduce the failure rate after installation of the system.

In addition, the optical core cable is composed of two cores (first and second cores), and when an abnormality occurs in the first core, the optical core cable is automatically switched to the second core, so that even if a failure occurs on any one optical cable, This is to ensure that the monitoring and alarm functions of the system are always on 24 hours without interruption.

In addition, the monitoring camera modules installed in a plurality of areas in the central control room are configured to be linked to a single optical core cable in a multi-type configuration by an optical relay device so that users can monitor high quality images quickly and easily. will be.

In general, the area / fence surveillance and alarm system is to block the inside and outside to secure the security within a certain area and to monitor the inside to prevent the observation or intrusion from the outside in advance, while an abnormal symptom is found. Whenever possible, it refers to a facility that promptly alerts you to the situation.

These area / fence surveillance and alarm systems require that the following conditions be met:

1. Surveillance video signal shall be guaranteed for 24 hours without disconnection through main and reserve lines.

2. In the case of military units, the overall length of the fence is much longer than that of general buildings and exposed to the external natural environment. Therefore, the influence of the external environment (lightning, electromagnetic waves caused by power lines, etc.) should be minimized.

3. The transmission of video surveillance signal should never be interrupted even if the video cable is cut by external force.

4. In consideration of the minimum operation and reaction time of the guards against abnormal movements at night, the performance of the equipment should be considered to ensure that the watch is at least 700 meters under moonlight, and the equipment to supplement them (border light, infrared ray) Etc.) should be secured.

5. Security must be secured to ensure that monitored video signals are not leaked by physical or electronic means.

6. When the fence alarm is issued, the camera should be able to automatically track intruders.

7. It must be easy to install and interwork with other systems.

8. Cable installation between camera and control room should not be complicated and easy to expand and transfer.

9. It should be able to interwork with national communication network and various electronic alarm systems.

In the existing area / fence surveillance and alarm system, as shown in Fig. 1, a number of camera modules (usually dozens or more) are directly connected to the central control room in a one-to-one manner. Accordingly, as many optical cables as the number of surveillance cameras were installed between the central control room and each camera module to transmit the surveillance and alarm information.

The conventional technology configured as described above is the most faithful configuration to prevent the overall disconnection of the monitoring information and to prevent the leakage of the monitoring information, according to which the leakage prevention of the information is most securely secured, and the phenomenon of the monitoring information being disconnected at the same time is prevented. As a result, the security of the surveillance and alarm system can be secured to the maximum.

However, in the conventional system configuration method, all the video / data / audio signals obtained from each video / data / audio monitoring device must be transmitted to the central control unit and the monitoring system through the direct input / output port in a one-to-one manner. As a result, the cost of laying the cable is very large and the working air is very long.

In addition, the configuration of the conventional monitoring and alarm system as described above complicates the network configuration and greatly increases the total amount of lines exposed to the external environment, thereby causing the system to be affected by the external environment (natural disasters and other facilities construction, etc.). Artificial damage, or the effects of electromagnetic waves, etc.) is the leading cause of failure.

In addition, since the overall length of the communication line is significantly longer, there is a problem of greatly increasing the amount and time of manpower and materials required for the construction and maintenance of the communication line.

The present application was devised to solve the above problems,

The optical cable is divided into two optical core cables in the entire area where the facility is to be monitored and alarmed, and the four or more surveillance camera modules (usually dozens or more) are scattered throughout the area requiring monitoring. After configuring each set of, connect it to one video / data / audio server (V / D / A server) and integrate it, and connect it to the optical repeater through LAN cable.

By linking all the optical repeaters to the main and the two optical core cables respectively, the system is configured to be connected to the central control unit and the monitoring system through a switch hub or a multi board, and the central control unit and the monitoring system installed in the central control room. It aims to drastically reduce the amount of communication network installed between monitoring devices installed on site.

In addition, by constructing the communication network of the system in the manner of main and buoyant cable cores, even if an error occurs in any one core, the communication network can be configured by another core immediately so that the information of the information is never reduced even though the total amount of lines is reduced. Another purpose is to ensure no breaks.

When an error occurs in any of the devices connected to another optical cable core, the communication network is immediately switched to another optical cable core and an alarm is alerted so that the central control room can check it immediately in case of an error and maintain the security of the facility. Another purpose is to make it complete.

In addition, if the facility needs to be expanded, the monitoring device that needs to be expanded can be expanded and installed through the optical relay installed in the installed optical cable core. Another purpose is to make it easy to expand and expand the system.

In addition, it is another object to improve the problem that the transmission distance is limited due to the characteristics of the line, unlike the prior art by enabling the multi-transmission of data up to 100km by the optical relay device.

Referring to the operation of the present application configured as described above are as follows.

First, a signal related to the outer fence situation detected from the fence monitoring sensor cable 210 is first relayed through the LU 230 and received by the PM 240.

The PM 240 receiving the fence monitoring signal converts the signal from an analog signal into a data (digital) signal, processes the signal, and then relays the signal to the LU 230, and then transmits the signal to the next PM 240. do.

The PM 240 receiving the data signal via the LU 230 transmits the received signal back to the adapter 250, and the adapter 250 converts the received electrical signal back into an optical signal to provide an optical relay device. And the signal is transmitted to the switch hub 720 via the first optical cable core 610 or the second optical cable core 620.

The video / data / audio signal received by the switching hub 720 is distributed according to a preset plan, and then switched to be transmitted to the central controller 710.

At this time, an embodiment of the signal distribution plan applied is shown in the following table.

Information rank Number of bits allocated Content of the information 01 One Type of information (video / audio information or fence surveillance information) 02 6 Monitor address (up to 64) 03 One Option information 04 n data

In addition, the central control unit 710 receiving the signal output from the switching hub 720 processes, analyzes, and judges the received signal, and transmits the signal to the fence monitoring monitor 810 and the integrated monitoring monitor 830. By outputting and displaying each of them, the worker (manager) is informed visually and acoustically.

When installing the MicroPoint senser cable (sensor) on the fence, sensor cables are installed at 200m intervals from the PM (Process Module) installed at the initial position of the fence in the central control room. When an intruder detects a collision due to impact or cutting on the fence, it detects and analyzes the signal reflected on the cable due to the impact and converts the detected analog surveillance signal into a data signal and relays it every PM. -LU-PM-TU is installed in order.)

When the cable length is over 200m, LU (Link Unit) is installed to transfer the detected data signal and power in the middle, PM is installed again at 200m and LU is installed at 200m to extend the sensor cable. And install TU (Termination Unit) terminating sensor signal at the end.

When an intruder crosses or cuts the fence of the PM section, the MicroPoint senser cable installed in the fence detects it and transmits the data detected by the processor module (PM), the PM sends the signal detected by the LU, and the LU receives the received data signal. And transmits this data back to PM, and PM transmits this data to RS-422 signal to the fence monitoring computer of the central control room and displays the intrusion location on the computer monitor MAP and issues an alarm alarm through the alarm device 840. .

On the other hand, when the video and audio information of a certain region is input to the V / D / A server 300 via the transmission and reception device 113 through the CCTV 111, the signal is a CCTV optical relay device through the LAN cable 410 Is sent to 400. The video and audio information received by the CCTV optical relay device 400 is transmitted to the switch hub 720 via the main optical cable core 610. The video and audio signals received by the switching hub 720 are distributed and switched in the switch hub and then transmitted to the central controller 710.

The signal processed, analyzed, and judged by the central controller is output to the area image / audio monitoring monitor 820 and the integrated monitoring monitor 830, and is displayed visually and audibly to the worker (manager).

On the other hand, after the video and audio signal or the fence monitoring signal input through the main optical cable core 610 is always analyzed and judged by the central control unit 710, if any one of the above signals is set in advance (for example, 3 seconds), the central control unit 710 immediately detects this and switches the optical cable core to the buoyancy cable core 620 to immediately resolve the situation in which the function of the system is stopped due to the absence of a monitoring signal, and then alarms it. The device 840 alerts the operator so that the situation room worker can immediately maintain it.

4 shows a flow in which the central controller 710 detects abnormalities of the optical core cables 610 and 620. To explain this,

First, a step of monitoring a signal received from the switch hub 720 is entered.

Subsequently, whether there is a signal input from the main optical cable 610 is monitored. (Step S-1)

Next, if it is confirmed that there is a signal input from the main optical cable 610, it moves to the step of performing the monitoring operation, and if there is no signal input from the main optical cable core 610, it moves to the step of checking the time. (Step S-2)

Check the disconnection time of the next signal to check whether the preset time (e.g. 3 seconds) has elapsed, and if 3 seconds have not elapsed, continue checking the presence or absence of the signal of the main fiber cable core. Go to. (Step S-3)

Next, if no signal is input from the main optical cable even after 3 seconds has elapsed in step S-3, the optical cable core is immediately switched to the negative optical cable 620. (Step S-4)

Subsequently, the alarm device 840 alerts that an abnormality has occurred in the communication line of the main optical cable core 610. (Step S-5)

Subsequently, it is monitored whether there is a signal input from the negative optical cable 620. (Step S-6)

Next, if it is confirmed that there is a signal input from the negative cable 620, it moves to the step of performing a monitoring operation, and if there is no signal input from the negative cable cable 620, it moves to the step of checking the time. (Step S-7)

Check the disconnection time of the next signal to check whether the preset time (e.g. 3 seconds) has elapsed, and if 3 seconds have not elapsed, continue checking the presence or absence of the signal of the buoyancy cable core and if 3 seconds have elapsed Go to. (Step S-8)

Next, if no signal is input from the auxiliary cable even after 3 seconds has elapsed in step S-8, the alarm device 840 immediately alerts that an error has occurred in the communication line of the auxiliary cable core 610. (Step S-10)

In addition, if it is necessary to expand the video / audio surveillance cameras 110 to 140 due to the expansion of the facility during use, a new video / audio surveillance camera to the connection terminal of the pre-set CCTV optical relay 400 in the idle state By combining a plurality of units in a set by connecting through the V / D / A server 300 and the LAN cable 410 it is possible to simply expand the system.

In addition, if there is a need to expand the fence monitoring system 200 due to the expansion of the fence facility during operation of the system, a new fence monitoring sensor 210 is connected to the connection terminal of the preliminary fence light relay 500 which is set in the idle state. And TU 220, LU 230 for processing the same signal. By connecting and connecting the LAN cable 410 including the PM 240, it is possible to simply expand the fence monitoring system.

By configuring the CCTV system 100 and the fence monitoring system 200 to be configured and operated as described above, it is possible to drastically reduce the installation cost and air of the system without affecting the security of the system. An alarm system can be provided, the system can be expanded by a very simple method, and the maintenance and repair costs of the device can be reduced to less than half by a relatively simple maintenance system.
