Description

TECHNICAL FIELD [0001] The present invention relates to a fence monitoring system and a method for changing a sensitivity of a complex sensor using an intelligent complex sensor,

The present invention relates to a fence surveillance system using an intelligent complex sensor comprising a combination of an acceleration sensor and an ultrasonic sensor for use in a facility to be protected from external intrusion such as a military boundary fence and a security fence against a major security facility, ≪ / RTI >

In a confrontation area such as a military demarcation line, soldiers who are watchdogs are placed close to the army line on a long-distance line and are directly under surveillance. This means that excessive soldiering work and excessive fatigue due to repetitive boundary work can cause frequent accidents.

The boundaries in these barbed areas are particularly problematic at night, where there are more field restrictions than daytime.

The nighttime boundaries, where there is a high risk of infiltration, are monitored by a supervisor working at a set interval of two to one set.

The border by these soldiers is a very effective way to deal with them immediately, but there is also a problem of border failure due to cumulative fatigue and monotony of soldiers.

In addition, it is always worried that the early detection failure of humans due to the visual sense, hearing,

Thus, a device or a facility for many types of boundary refinements has been conventionally proposed.

Aids for identification such as search lights and night vision goggles are also used. It is equipped with cameras that can operate day and night by applying IT technology, and supplement the boundaries in the control room.

In order to compensate the mistake of the visual control, the camera image is automatically analyzed to generate a boundary alarm.

Another attempt is to add a closed loop conductor to the fence to detect a break in the defensive fence (ironware) and to warn the intruder that the closed loop of this conductor is shorted.

Another known technique is to construct a system and protect the facility by using a sensor that captures the intruder's movement on the front (outside) of the defensive fence, which is divided into configurations related to the technical idea to be implemented by the present invention .

According to the prior art using sensors for capturing an intruder in front of the defensive fence, an acceleration sensor for detecting acoustic vibrations such as vibration, shaking, rubbing and cutting of the fence is measured and an alarm is given when the set value is satisfied .

In addition to the acceleration sensor, there is also known an apparatus for alarming an alarm by detecting a spatial approach to an intruder in front of a fence by measuring reflected waves using ultrasonic waves.

However, according to the related art, when an alarm level is preset and a signal exceeding a set level is generated, an alarm is generated. When the set level is set sensitively, there is a problem of an erroneous operation, which makes it difficult to trust the alarm device.

On the contrary, when the set level is set to be insensitive, it is difficult to obtain an alarm signal, so that it is mainly set to be sensitive. As a result, it is difficult to identify an appropriate intrusion and it is sensitive. Therefore, There is a problem that the installation of the alarm device causes confusion at the boundary, since the alarm is ignored and the response to the actual situation is not properly made.

A plurality of the main controllers 20 are formed, The server 30 is connected to the server 30 via the network.

The server 30 can be a PC-class or a server-class computer, and forms an Ethernet communication network by sharing a communication protocol with the main controller.

The server 30 is configured to identify at least the lower main controller and the composite sensor module which is the terminal sub-device subordinated to the main controller, and to specify the detection sensitivity of the ultrasonic sensor and the acceleration sensor.

The composite sensor module 10 includes a can communication module 11 for performing can communication with the main controller 20, an acceleration sensor 13 and an ultrasonic sensor 15 for substantially detecting the intrusion, A memory 17 including a sensitivity level information and a sensor sensitivity change program, and a central processing unit (CPU), and is activated in response to a main controller request subscribed to can communication and transmits hardware configuration information including an address (S301), a detection sensitivity requesting step (S302) for requesting a main controller to detect a detection sensitivity which is binarized during normal and intrusion, a detection sensitivity storing process for storing detection sensitivity transmitted from the server through the main controller (S303), a detection sensitivity change storing step (S304) of receiving and storing the changed detection sensitivity through the main controller according to the detection sensitivity change of the server side, (S305) for sending an Alive signal to the main controller (S305), an intrusion detection process (S306) for monitoring the intrusion by the stored detection sensitivity, generating an alarm signal when an intrusion occurs, and transmitting the alarm signal to the main controller .

Wherein the detection sensitivity level designated by the server is divided into levels sequentially increasing or decreasing, and a sensitivity level applied at a low level in a normal state according to the detection sensitivity level, Designating the sensitivity level as a sensitivity level changing to a high level, and transmitting the designated level to the composite sensor module through the main controller to detect the intrusion.

The detection sensitivity level, which is divided into increasing or decreasing levels sequentially, can be understood as a level divided into at least 100 quartiles.

That is, assuming that the minimum detection sensitivity level reference value is "0 ", the maximum detection sensitivity level reference value will be" 100 ", and the lower the detection sensitivity level, the deeper becomes the insensitivity state. .

The composite sensor module is adapted to apply the level of the sensor driving reference value to the sensitivity level of the normal state and the sensitivity level of the detection state, and the insensitivity and the sensitivity level have any one of the 100th level as the reference value.

As shown in FIG. 5, the method for changing the sensitivity of the composite sensor module 10 is as follows. In accordance with the setting of the detection sensitivity of the binarized detection sensitivity set by the server through the execution of the intrusion detection routine and transmitted via the main controller, A step S2 of detecting a sensitivity of the sensor and an acceleration sensor in a non-sensitive state, a step S2 of detecting an ultrasonic sensor for detecting an intrusion of the ultrasonic sensor while maintaining the set sensitivity with a normal detection sensitivity, A detection sensitivity changing step (S3) of reading the detection sensitivity at the time of intrusion when the ultrasonic sensor is detected and maintaining the detection sensitivity of the ultrasonic sensor and the acceleration sensor in a sensitive state, and further detecting by the acceleration sensor An alarm step (S6) for generating an alarm when an intrusion is detected in all the heterogeneous sensors by an acceleration sensor detection step to be detected If the acceleration sensor is not detected further in the sensing sensitivity sensitive state, the ultrasonic sensor is continuously returned to the initial state in the state where the detection is stopped by the ultrasonic sensor detection step S5 to compare whether the ultrasonic sensor continuously detects the intrusion If the detection continues, the control method returns to the ultrasonic sensor detection step and changes the sensitivity so as to perform continuous intrusion detection.

Therefore, the malfunction of the normal ultrasonic sensor and the acceleration sensor is greatly reduced, thereby realizing accurate detection and alarm.

In this case, the binarized detection sensitivity is expressed as a sense of perception during the period of insensitivity and intrusion, but it can be set to be about 30 at the time of a break and 85 level at the time of an intrusion when it is evaluated at the 100th level. The settable and changed detection sensitivity is stored in the main controller and the main controller functions to facilitate management at the center by transmitting the changed detection sensitivity to the multiple sensor module of the subordinate subordinate device.

In addition, if an alive signal for line check is not received due to a failure of the composite sensor module 10 installed in a wide area or a loosening of a communication line, the corresponding terminal is identified, replaced, and maintained, and intrusion is detected The complex sensor module that generates the alarm alarm transmits its own address to the main controller and / or the server, thereby functioning to identify the position of the complex sensor module.
