Description

Security system and method

The present invention relates to a security system and method.

The security system is a detector (or sensor device) that can detect external intrusion into a specific space (e.g., inside a building such as an office or general home), and collects the detected signal and transmits it to a control station that acts as a security agent. It refers to a system equipped with a communication system.

In a security system, the security controller recognizes the state of the detector connected to the detection loop based on the voltage applied from the detection loop.

1 is an exemplary diagram showing a method of checking a detection loop by a security controller included in a security system.

As illustrated in the accompanying FIG. 1, the security controller 1 recognizes the state of the detectors 2 and 3 connected to the detection loop by using the voltage level applied to the M terminal when the voltage is supplied to the B terminal. The detector 2 may be a heat ray detector, and the detector 3 may be a magnetic sensor. When alerting to the security area, the detector 2 is shorted and the detector 3 is open, thereby forming a detection loop consisting of the detector 2 and the terminating resistor 4. The terminating resistor 4 is connected in parallel to the detector 2 and provides a steady-state reference voltage level.

When an abnormality is detected in the crime prevention area, the detector 2 is opened and the detector 3 is short-circuited. Specifically, the detectors 2 and 3 forming the sensing loop maintain a constant voltage level by the termination resistor 4 and the impedance of the sensing circuit configured inside the M stage at the boundary. Here, when the sensor 2 detects a change, the state of the sensor 2 is opened, the voltage supply between the detection loops of the B and M stages is stopped, and a voltage fluctuation occurs at the M stage. Then, the security controller 1 detects the signal in which the voltage fluctuation has occurred as open. In addition, when the sensor 3 detects a change, the sensor 3 is short-circuited, and a voltage fluctuation occurs between the B terminal and the M terminal. Then, the crime prevention controller 1 detects a signal in which voltage fluctuation has occurred as a short circuit.

However, if the detector is not installed and only the terminating resistor is installed in such a sensing loop, a constant voltage level is maintained between the B and M terminals, that is, it is maintained only as normal. This can be called'random looping'.

However, there is no way to check whether such an arbitrary looping or not, and since it is not possible to know this even if only the terminating resistor is falsely installed in the detection loop, no detection, such as not being able to detect even if an abnormality occurs, may occur.

The problem to be solved by the present invention is to provide a security system and method capable of more accurately detecting whether an abnormality occurs.

In addition, a problem to be solved by the present invention is to provide a security system and a security method for preventing no detection from occurring due to random looping in a detection loop.

Determining that the ground, the plurality of detectors operate normally and the crime prevention area is in a normal state; And determining that an abnormality has occurred if the detection by the plurality of detectors is not performed in a preset order when the security control device is set to the security release mode, and the preset order is the access to the security area. This indicates that the detection of the detectors positioned based on the initial position is performed sequentially.

The security area may include a first area including an initial position at which access to the security area is performed, a second area adjacent to the first area, and a third area adjacent to the second area, and the plurality of detectors The fact that the detection by is performed in a preset order may indicate that the detection of the detector located in the initial position, the detection of the detector located in the first area, and the detection of the detector located in the second area are performed in order. have.

The step of determining that the abnormality has occurred may include detection of the sensor located in the second area or the detection of the sensor located in the third area after the detection of the sensor located in the initial position, indicating that intrusion has occurred. Judging; And determining that a malfunction including random looping has occurred if the detection of the detector installed in any one of the first to third regions is not performed after the detection of the detector positioned at the initial position. It may include.

In addition, the determining that the abnormality has occurred may include determining that an intrusion has occurred if the detection by the plurality of security guard release detectors is not performed in a preset order; And if detection by one of the plurality of detectors is not performed for a set time while the detection by the plurality of detectors is not performed in a preset order, it is determined that a malfunction including random looping has occurred. It may include steps.

On the other hand, the method may further include the step of setting the security mode when the security control device is not all detected by the plurality of detectors for a set time.

In addition, the method, the security control device, when the security mode is set, the steps of sequentially checking the operation state of the plurality of detectors at a set interval; In the operation check, if one detector is detected and then another detector is continuously detected for more than a set number of times, determining that intrusion has occurred.

In this case, the method may further include determining that noise has occurred when the detection is performed multiple times by the detector when the operation is checked, and the detection is not continuously performed more than a set number of times. .

In addition, the method may further include determining that a malfunction has occurred when no detection by any of the sensors is performed during the set time during the operation check.

The detection by the detector may indicate a state in which the detection loop formed by the corresponding detector is shorted or opened.

The ground, the plurality of detectors is configured to determine that it is operating normally and the security area is in a normal state, and if the detection by the plurality of detectors is not performed in a preset order, it is configured to determine that an abnormality has occurred, and the preset order Denotes that the detection of the detectors located based on the initial position at which the access to the crime prevention area is performed is sequentially performed.

The security area includes a first area including an initial position at which access to the security area is made, a second area adjacent to the first area, and a third area adjacent to the second area, and The fact that the detection is performed in a preset order may indicate that the detection of the detector located in the initial position, the detection of the detector located in the first area, and the detection of the detector located in the second area are performed in order.

If the sensor installed in any one of the first to third areas is not detected after the sensor positioned at the initial position is detected, it may be configured to determine that a malfunction including random looping has occurred.

The security control device may be configured to set a security mode when not all detection by the plurality of detectors is made during a first set time.

When the security control device is additionally set, and the security mode is set, the operation status of the plurality of detectors is sequentially checked at a set interval, and then one detector is detected, and then the other detectors are continuously detected more than the set number of times. If it is made of, it is determined that intrusion has occurred, and when the operation is checked, detection by the detector is performed multiple times and the detection is not performed continuously for more than a set number of times, it is determined that noise has occurred, and when the operation is checked , It may be configured to determine that a malfunction has occurred when no detection by any of the detectors is performed during the set time.

When it is determined, it may be determined that detection by a detector corresponding to the detection loop has been made.

According to an embodiment of the present invention, a change in the detection loop may be accurately recognized by checking for a random looping due to falsehood in the detection loop in the security system. Therefore, at the time of installing a security system or each security operation, it is possible to easily detect a case in which a false detector is installed in a state in which a detector such as a method sensor is not installed, and a random looping is performed.

Therefore, by accurately detecting whether a sensor malfunctions, unnecessary management and the like according to a malfunction check can be reduced, and since arbitrary looping can be detected, no detection can be prevented.

2 is a block diagram showing the structure of a security system according to an embodiment of the present invention.

As shown in FIG. 2, the security system 100 according to an embodiment of the present invention includes a security control device 10 and a detection unit 20.

The sensing unit 20 includes a plurality of detectors 21 (denoted by a representative number "21" for convenience of description). The plurality of detectors 21 may be connected in series or in parallel depending on their type (or use). The plurality of detectors 21 may be connected to the reference voltage, and may be connected to the reference voltage through a termination resistor. A plurality of detection loops may be formed by the plurality of detectors 21. For example, the method system 1 may form 8 sense loops or up to 15 sense loops.

The security control device 10 selectively operates a plurality of detection loops formed by the plurality of detectors 21 of the detection unit 20, and based on a signal output from the detection unit 20 through the operated detection loop. It determines whether or not an abnormality has occurred by determining whether the detection loop is short or open. To this end, the security control device 10 includes a detection signal output unit 11, a comparison unit 12 and a state determination unit 13. In addition, a power supply unit (not shown) for supplying power to the sensing unit 20 may be further included.

The detection signal output unit 11 is connected to the plurality of detectors 21 and receives and outputs a signal corresponding to a detection loop formed by the plurality of detectors 21. The sensing signal output unit 12 includes a plurality of input ports, that is, a plurality of sensing loop terminals. The number of sensing loop input terminals may correspond to the number of detectors 21. The detection signal output unit 11 may select and output a signal provided through one detection loop from among detection loops respectively formed corresponding to the plurality of detectors 21. In this case, the detection signal output unit 11 may select one of signals input through a plurality of detection loop terminals based on a loop selection signal input through a separate terminal. The sensing signal output unit 11 may be implemented in the form of a MUX IC.

The comparison unit 12 compares and outputs a signal input from the detection signal output unit 11 with a reference voltage. The comparison unit 12 compares the input signal with a short reference voltage or an open reference voltage and outputs the comparison. Specifically, the comparison unit 12 compares a signal input from the detection signal output unit 11 with a short-circuit reference voltage to output a first comparison signal, and compares the input signal with an open reference voltage to obtain a second comparison signal. Prints.

The determination unit 13 determines whether the detection loop is short-circuited/opened based on a signal input from the comparison unit 12, and determines whether an abnormality has occurred according to the determination result. For example, specifically, the determination unit 13 determines whether the detection loop is short-circuited/opened based on the first comparison signal and the second comparison signal output from the comparison unit 12, and detects the corresponding detection according to the determination result. Determine whether an abnormality has occurred in the loop. For example, the determination unit 12 receives a first comparison signal through a first input terminal and a second comparison signal through a second input terminal.

The determination unit 13 may be implemented in the form of a processor IC, and may be configured to implement functions, procedures, and methods of the security control device 10 described herein. In addition, the determination unit 13 controls each component (11, 12) of the security control device 10, it is possible to manage the signal flow between each component (11, 12), or the determination unit (13) A processor implemented separately from and may control the respective components 11 and 12 to manage the signal flow between the respective components 11 and 12.

3 is a diagram showing an example of an installation example of a security system and a schematic structural example of a security control device according to an embodiment of the present invention.

The security system 10 according to an embodiment of the present invention performs security in connection with a plurality of detectors 21 installed in a security area (for example, a security area (SA)), as illustrated in FIG. 3. can do.

A plurality of detectors 21 are installed in the crime prevention area SA, and by this detector 21, a plurality of, for example, eight detection loops (LOOP 1, LOOP 2, LOOP 3, LOOP 4, LOOP 5, LOOP) 6, LOOP 7, LOOP 8) can be formed. The detection signal output unit 11 of the security control device 10 may select one detection loop from among eight detection loops (LOOP 1, ..., LOOP 8) and output a corresponding signal. For example, one sensing loop may be selected according to a signal provided from the determination unit 13, or eight sensing loops (LOOP 1, ..., LOOP 8) may be sequentially selected. In FIG. 3, it is exemplified that five detection loops (LOOP 1, …, LOOP 5) are connected to five detectors, but the present invention is not limited thereto.

The sensing signal output unit 11 selects and outputs one of the signals input through the eight sensing loop terminals respectively corresponding to the eight sensing loops 1LOOP, ... 8LOOP. The comparison unit 12 may include a first comparison unit 121 and a second comparison unit 122 as illustrated in FIG. 3. The first comparison unit 121 outputs a first comparison signal by comparing the voltage of the detection signal with a short-circuit reference voltage (eg, 8V). The second comparison unit 122 outputs a second comparison signal by comparing the voltage of the detection signal with an open reference voltage (eg, 2V). Here, it was exemplified that the detection signal output unit 11 selects and outputs one of the signals from a plurality of detectors, and the comparison unit 12 performs comparison with the reference voltage by inputting such one signal. The invention is not limited thereto. For example, the detection signal output unit 11 outputs signals from a plurality of detectors through a plurality of output terminals, respectively, and the comparison unit 12 is connected to each of the plurality of output terminals of the detection signal output unit 11 By implementing in the form of being implemented, each comparison unit may perform a comparison operation for each signal output from the Kimji signal output unit 11, respectively.

Meanwhile, the determination unit 13 includes a first input terminal SHORT receiving a first comparison signal and a second input terminal OPEN receiving a second comparison signal, as shown in FIG. 3. Based on the signals input through the input terminal SHORT and the second input terminal OPEN, the state of the detection loop that generated the detection signal is determined. The determination unit 13 generates a detection signal based on the first comparison signal and the second comparison signal output from the comparison unit 14 and input through the first input terminal SHORT and the second input terminal OPEN. It determines whether the detection loop is in a short state, an open state, or a normal state. Specifically, the state determination unit 13 is whether the detection signal is a short-circuit signal (a signal generated by the detector 21 in a short-circuit state), an open signal (a signal generated by the detector 21 in an open state), or It can be determined whether it is a normal signal. More specifically, when the first comparison signal indicates that the voltage of the arbitrary detection signal is higher than the short-circuit reference voltage (or voltage range), the state determination unit 13 If a short-circuit is detected (the detection loop of the corresponding detector is in a short-circuit state), and the second comparison signal indicates that the voltage of the arbitrary detection signal is lower than the open reference voltage (or voltage range), for example, the second When the comparison signal is high (HIGH) level), it is determined as open detection (the detection loop of the corresponding detector is open), and the voltage of the random detection signal is within the normal range based on the first comparison signal and the second comparison signal. , 4V~5V), it can be determined to be in a normal state. Here, the determination unit 13 may determine that the first comparison signal and the second comparison signal are in a normal state when the first comparison signal and the second comparison signal are at a low level.

However, in the above-described sensing loop, if a'random looping' occurs by installing only a terminating resistor without installing a detector, it cannot be detected. Therefore, in an embodiment of the present invention, it is determined whether a malfunction or intrusion has occurred based on the detection order of the detectors. Malfunctions here include random looping.

Next, a crime prevention method according to an embodiment of the present invention will be described.

Here, a security method according to an embodiment of the present invention is described as an example in which the security system according to an embodiment of the present invention is installed in a crime prevention area (SA) as shown in FIG. 3, but the present invention is not limited thereto.

For example, as illustrated in FIG. 3, the crime prevention area SA is divided into a plurality of areas. The crime prevention area SA is divided into, for example, a first area (①), a second area (②), and a third area (③). The first area (①) is an area including the entrance, the second area (②) represents the area adjacent to the first area (①), and the third area (③) is an area separated from the first area (①). Show. The entrance of the first area (①) includes a card reader, and authentication processing for the card of the visitor is performed by the card reader.

A plurality of detectors are installed in the crime prevention area SA, and specifically, for example, the detectors 21a to 21e are installed in the crime prevention area SA. The detector 21a is located at an initial position, that is, at the entrance to form a detection loop 1 (LOOP 1), and the detector 21b is installed in the first area (①) and forms a detection loop 2 (LOOP 2). In particular, the detector (21a) is installed at the entrance of the first area (①). The sensor 21c is installed in the second area ② and forms a sensing loop 3 (LOOP 3), and the sensor 21d is installed in the second area 2 and forms a sensing loop 4 (LOOP 4). The detector 213 is installed in the third area ③ and forms a sensing loop 5 (LOOP 5). The remaining sensing loops LOOP 6 to LOOP8 are not intended to be used here, and are not limited thereto. Here, when the detection loops are in a short or open state, it indicates that an error has occurred and "sensing" by the corresponding sensor is performed, and when the detection loops are in a normal state, an error does not occur and thus "detection" by the corresponding sensor is not performed It indicates that it is not in a state.

In an embodiment of the present invention, in an environment in which a detector is installed, as illustrated in FIG. 3, security is performed by linking with each detector, and in particular, security is performed while determining whether random looping occurs in the detector according to a set condition. do. Here, the security system 10 may operate in one of a security mode in which security is performed for the security area SA and a security release mode in which security is not performed for the security area SA. In an embodiment of the present invention, a security method is performed differently depending on whether the security mode or the security release mode is used to determine whether a malfunction or intrusion including random looping has occurred.

First, the security method in the security release mode will be described.

4 is a flowchart of a crime prevention method according to the first embodiment of the present invention.

In the first embodiment of the present invention, when the guard release mode is set, and when the detection of the detectors is performed in a preset order in the guard release mode, it is determined that the entrance is normally performed through the entrance and the operation of the detectors is normally performed. And, if the detection of the detectors is not performed in the preset order, it is determined that an abnormality has occurred. Here, the abnormalities include intrusion by an intruder, defective detector, random looping, and the like. Here, the preset order indicates that detection is performed in the order of detection of a detector at an initial location (eg, entrance) -> detection of a first area -> detection of a second area. The detection of the first area or the detection of the second area indicates that detection by a sensor located in the corresponding area has been performed.

Specifically, as shown in FIG. 4, in the guard release mode (S100), it is determined whether the sensor located at the initial position (the sensor 21a installed at the entrance) is detected (S110), and the sensor at the initial position is When the detection is made, it is determined whether the detection of the first area (detection of the sensor 21b of the first area ①) is performed (S120). After authentication processing is performed through a card reader at the entrance of the first area (①), the guard release mode is set, and the sensor 21a located at the entrance is detected, in general, the user who has passed the entrance is the first area. You have no choice but to enter (①). Therefore, in order to determine whether the sensor 21b located in the first area (①) corresponding to the entrance normally detects the user entering the first area (①), the sensor 21b of the first area (①) Determine whether detection is taking place.

If it is determined that the detection of the first area is performed, it is determined whether the detection of the second area is performed (S130). In the expense release mode, after the user enters the first area (①), the user must move through the second area (②) adjacent to the first area (①). Accordingly, when the first area is detected, it is determined whether the detectors 21c and 21d of the second area 2 are detected.

When the second area is detected after the first area is detected, it is determined that the entry is normally made through the entrance and the detectors are in a state in which the operation is normally performed (S150).

On the other hand, when detection is not performed in the order of detection by the detector 21a located at the entrance, detection of the first area, and detection of the second area, it is determined that an abnormality has occurred.

Specifically, detection of the sensor 21a located at the entrance is not performed, or the first area detection is not performed after the detection of the sensor 21b located at the entrance is made, or the sensor 21a located at the entrance is not detected. When the detection is made and the first region is detected but the second region is not detected, it is determined whether another region is detected (S150). If another area is detected in step S150 (for example, when the first area is not detected and the second area or the third area is detected after the detection of the initial position sensor), the other area is It is determined that intrusion has occurred (S160).

If no other area is detected in step S150 and detection by the detectors 21a to 21e installed in the crime prevention area SA during a set time (eg, a first set time) (S170), the detector It is determined that a malfunction such as a defect or random looping has occurred (S180).

In this way, after the guard release mode is set, if the detection of the detector at the initial position is performed in the order of detection of the initial position -> detection of the first area -> detection of the second area, the entrance is normally made through the entrance and the detectors It is determined that the operation is in a normal state. In addition, if detection is performed in a sequence different from the preset sequence after the security release mode is set, it is determined that intrusion has occurred. In addition, if detection by at least one of the detection loops (detection by any one of a plurality of detectors) is not performed for a set time after the guard release mode is set, it is determined that a malfunction has occurred. The determination result may be notified to other devices (servers, administrator's terminals, etc.) through a communication device (not shown).

On the other hand, if detection by all detectors is not performed for a preset time (second set time) in the security release mode, that is, if detection by all detectors installed in the entire crime prevention area (SA) is not performed (e.g., 2 If both LOOP1~LOOP operate in a normal state where no abnormality occurs during the set time), the guard mode can be set automatically.

Next, a security method in security mode will be described.

5 is a flowchart of a security method according to a second embodiment of the present invention.

In the second embodiment of the present invention, the guard mode is set, and if detection by at least one of the detection loops (detection by any one of a plurality of detectors) is not performed during the set time in the guard mode, a malfunction has occurred. Judge.

Specifically, as shown in the accompanying Figure 5, in the security mode (S300), the security control device 10 checks the state of the detection loops, that is, the operation state of the detectors at set intervals (S310). The determination unit 13 of the method control device 10 outputs a signal for sequentially checking the detection loops at a set interval (eg, 80 ms) to the detection signal output unit 11, and the detection signal output unit 11 ) Selects and outputs a signal from a detector forming a corresponding detection loop according to the signal, so that the operation state is determined through the comparison unit 12 and the determination unit 13 for the selected signal.

6 is an exemplary timing diagram illustrating a detection loop check according to a second embodiment of the present invention.

For example, as illustrated in Figure 6, sense loop 1 (LOOP 1), sense loop 2 (LOOP 2), sense loop 3 (LOOP 3), sense loop 4 (LOOP 4), sense loop 5 (LOOP 5) You can check the status of each detection loop at set intervals in the order of ).

The operation states of the detectors are checked in sequence at set intervals, and if the detection of the detector is made once (S320) and then continuously detected for more than the set number of times (S330), it is determined that an emergency has occurred (S340).

On the other hand, if the detection of the detector is not performed continuously for more than a set number of times after being detected once, it is determined that the detectors operate normally and noise has occurred (S350).

7 is an exemplary view showing a determination result according to a detection loop check according to a second embodiment of the present invention.

For example, as shown in FIG. 7, when detection is made four or more times in succession after one detection is made in the guard mode, it is determined that a detection emergency has occurred, and a detection/real report (actual alarm) is notified. If detection is not made more than four times in succession after one detection in guard mode, it is judged as normal/noise and notified.

On the other hand, if the detection is not made once in step (S320) and the detection is not made during the set time (S360), that is, in the case of no detection by any detector during the set time in the security mode state, the detector It is determined that a malfunction, such as a defect or random looping, has occurred and is notified (S370).

According to the embodiments of the present invention, it is possible to accurately detect malfunctions and intrusions based on whether crime prevention is performed in different ways according to the security mode or the security release mode, and in particular, the detection of the detector is performed according to a preset order in the security release mode. have. Therefore, by accurately detecting whether a sensor malfunctions, unnecessary management and the like according to a malfunction check can be reduced, and since arbitrary looping can be detected, no detection can be prevented. In addition, it is possible to determine whether the detection of the detector is caused by noise in the guard mode.
