Description

Intruding Surveillance System and Method Using a Pressure Sensor and a Cable Cutter Established Each Meter in Perimeter Security Control System}

The present invention is made of a monitoring cable installed on the outer periphery of the monitoring area, poles and cable cutouts that are set at regular lengths of the monitoring cable so that the tensioned monitoring cable is cut off when a certain force is applied when an external intrusion occurs. Limit the number of installation of the diagnostic module, enable detailed and accurate intrusion detection, and configure the cable fault diagnosis module to accurately identify the location and location of the intrusion by using the cable fault diagnosis module. It is an external security system device that collects the results from the diagnosis module, stores / displays and takes appropriate measures, and displays the intrusion occurrence position and evidence through interworking with the image storage device.

Cable fault diagnosis module using TDC (Time-to-Digital Converter) module has accuracy (error rate) of 1% or less, so if the length of the cable to be measured is long, a large part of the cable may be out of the measurement range. Can cause errors. Conventional outer security system installs a diagnostic device at a distance between the fence and fence around the cable as much as the measurable distance of the cable fault diagnosis module, or installs a cable fault diagnosis module at regular intervals as a part of reducing the error distance. Using the installation method, each cable fault diagnosis module periodically monitors the normality of the corresponding monitoring cable and transmits the result to the central control unit. However, when the diagnostic system is installed at intervals of the maximum measurable distance of the cable fault diagnosis module, the outer guard system has a limitation in accurate measurement due to the characteristics of the above-described accuracy of the cable fault diagnosis module. If the distance of the measurement monitoring cable is not minimized, the cable fault diagnosis module cannot accurately detect the external intrusion. In other words, the longer the length of the cable to be diagnosed in the outer security system, the longer the length of the error, the lower the accuracy of the measurement.

In addition, if the cable fault diagnosis module is installed at short intervals, it is economically expensive to purchase the number of cable fault diagnosis modules that are installed. The problem of adding numbers is very inefficient. In addition, there is a security problem of accurate location tracking and the lack of corresponding evidence in case of intrusion.

The technical problem to be achieved by the present invention is an automatic cable cutting machine for poles erected at intervals that can minimize the accuracy (error rate) of the TDC module, instead of installing a large number of cable fault diagnosis module in the monitoring cable installed on the fence, building exterior This cable is automatically cut when a certain amount of force is applied from the outside, and the cable fault diagnosis module measures this position to accurately determine the intrusion and location, and the intrusion position is measured in meters. It is possible to detect and record the evidence data in the camera in conjunction with the image data, and transmit it to the central control device and store the data.

The present invention provides a monitoring cable installed in the area to be monitored, such as rail fences and buildings, and poles at meter intervals on the monitoring cable so that the monitoring cable is accurate and sensitive, and the automatic pole is mounted on the built-in pole. When a certain force is applied, the sensor detects this and cuts the cable automatically so that the cutter automatically cuts the cable, and the cable fault that detects the intrusion by tracking the position of the cut cable in meters by using the cable fault diagnosis module. It comprises a diagnostic module, a central control unit that collects information from the cable fault diagnosis module in real time and takes appropriate action, and an image storage unit that stores the tracked and evidence image data of the detected position as data.

The cable cutout unit is installed in meters to minimize the TDC accuracy, instead of significantly reducing the number of installation of the cable fault diagnosis module, enabling accurate location information of the cable fault diagnosis module, and a pressure above a certain force is applied to the monitoring cable. When mounted, the sensor is mounted to immediately operate and cut the cable. The cable fault diagnosis module monitors the cable status in real time, maintains the monitoring function even when the cable is connected or bypassed, and immediately displays the intrusion and position detection result when the cable is cut.

When the intrusion occurs, the video storage unit interlocks with the central control unit, collects information on the intrusion occurrence area for each camera, stores video recording and data of the intrusion occurrence area, and transmits the data through the network to secure evidence. It is characterized by.

The outer guard system apparatus using the monitoring cable cutout and the cable fault diagnosis module of the present invention having such a feature is a process of automatically cutting the cable when a certain force is applied to the cable when an intrusion occurs, and in this case, the cable fault diagnosis module appears. Measuring damage by using the reflected waveform of electromagnetic waves, generating a alarm in the central control unit that collects information from the cable fault diagnosis module in real time, and confirming the intrusion through interlocking with a video device such as a camera It consists of recording the intrusion area and transmitting the recorded data.

Figure 1 shows the configuration of the present invention as described above, when explaining the overall system configuration and operation of the present invention.

When the poles 2 are installed in meters of the monitoring cable 1 installed around the monitoring area, and the cable cutouts 3 installed on the basis of the poles 2 and a constant force is applied to the cable when an intrusion occurs, the cutouts The sensor 4 is recognized by the sensor 4, which operates the cable cutter 5 to cut the cable, and the cable is detected by the cable fault diagnosis module 6, which immediately monitors the cable in real time. The fault diagnosis module transmits the damage information of the cable to the central control station (7). At this time, the cable fault diagnosis module can monitor using the reflected electromagnetic wave even when the broken cable is reconnected or bypassed. The central control station 7 receives information from the cable fault diagnosis module, and immediately controls the image device 8 to record the intrusion occurrence area, determine whether an intrusion occurs, activate alarm / alarm generation, and record the recorded image. Receive data and back up to storage.

At this time, maintaining the interval of the pole (2) to 1m is to enable a more accurate location of the cable fault diagnosis module in accordance with the cable fault diagnosis.

Figure 3 shows the configuration of the cable cutting portion 3 in the cable cutter of the device of the present invention, the cutter 102 fixed by the spring 101 detects the shaking of the fixing support 104 when a force is applied to the cable When the sensor 103 senses, the fixing pedestal 104 is broken, and the cutter 102 is operated due to the fixed pressure applied to the spring 101 of the cutter, thereby cutting the cable.

In case of external intrusion, the pole installed to pinpoint the damage of the cable such as short circuit or disconnection, and the pressure sensor (4) mounted on the pole detects the pressure applied to the cable for intrusion into the monitoring area. Immediately, the sensor is operated and delivered to the cutting unit 3. At the same time as the cut, the cable connected to the pole is disconnected and the cable fault diagnosis module, which monitors the cable in real time, detects the cable fault and sends this information to the central control station. The poles erected at meter intervals result in accurate calculations of the location of the damaged area in meters, and the cable fault diagnosis module captures this location information. The central control station controls the imaging device based on the received data to determine whether an invasion of the damaged position occurs, and when it is determined that the intrusion occurs, an alarm is issued through the alarm device 202 immediately. At the same time, information stored in the image storage device is received and stored in the data backup device 201.

Due to the present invention, it is possible to minimize the error rate of the cable fault diagnosis module in the outer guard system to enable accurate location tracking within a metric unit when intrusion occurs, as well as the need to install the cable fault diagnosis module at regular intervals around the monitoring area. It is possible to reduce enormous costs and to provide accurate evidence by interlocking imaging devices.
