Description

Heat ray sensing device and method thereof

The present invention relates to a sensing device and a method thereof, and more particularly, to a heat ray sensing device and a method using a heat ray sensor.

In general, security devices detect intruders using various sensors, and devices that detect intruders using a hot wire sensor are used. The hot wire sensor detects the change of its value by using infrared rays and determines the presence or absence of the human body in the surveillance area. It is divided into two types, active and passive, according to its operation principle.

The active heating sensor device installs the receiver and the transmitter in a fixed place in a certain place and in a certain direction, and the infrared receiver receives the infrared rays from the transmitter. If an object is inserted between them, the infrared detection of the receiver disappears. Device. The passive hot wire sensor device is a device that installs only a pyroelectric infrared sensor having a wide viewing angle, and when the human body approaches the viewing angle, the sensor detects a corresponding infrared ray and generates an alarm.

Among such hot wire sensors, passive hot wire sensors having a wide viewing angle are widely used. For example, passive hot wire sensors detect that far infrared rays having a peak at about 8 to 10 μm are emitted from a human having a body temperature of 36 to 37 ° C. do. Thermal sensors and quantum sensors are used to detect such far infrared rays. Thermal sensors are widely used rather than quantum, for example, thermistors, bolometers, thermopiles, pyroelectric elements, etc. are typically used. In particular, infrared pyroelectric elements are widely used in security systems.

A conventional security device using a heat ray sensor including such an infrared pyroelectric element is generally installed on a ceiling or a wall of a region where a heat ray sensor is to be monitored, and when an intrusion detection is detected from a heat ray sensor, a corresponding detection signal is transmitted to a control sensor. It operates by outputting a warning signal. Accordingly, in order to install the hot wire sensor on the ceiling or the wall, a wall mounting work is required, and additional installation work such as the perforation and wiring work of the wall or the ceiling is required, which makes it difficult to install and use the hot wire sensor in the monitoring area. .

In addition, if the infrared ray is detected from the detectable area while the heating sensor is located on the ceiling or the wall, it is determined that the intrusion occurred. Therefore, even if there is a small animal such as a pet, not a human, in the detectable area, Malfunctions such as this often occur.

In the heat ray detection apparatus, a determination unit may be further included to determine whether a person is detected in the surveillance area based on detection signals corresponding to the plurality of detection modules output from the signal processing unit. The determination unit may determine that a person is detected in the monitoring area when the detection signals indicating that the infrared rays from the monitoring target are detected in all the monitoring zones of the plurality of sensing modules. In addition, when the detection unit outputs a detection signal indicating that only one sensing module of the plurality of sensing modules senses infrared rays from the monitoring target in the corresponding monitoring zone, the determination unit determines that the target except the person is detected in the monitoring region. can do.

As shown in FIG. 1, the apparatus for detecting heat rays 1 according to an exemplary embodiment of the present invention may include a lens unit 10, a plurality of sensing modules 11 and 12, a signal processing unit 20, and a determination unit 30. And a communication unit 40. In addition, it may further include a warning means (not shown) for outputting a warning signal when it is determined that an intrusion has occurred.

The lens unit 10 collects infrared rays from the monitoring target and sends them to the sensing modules 11 and 12. In particular, the lens unit 10 collects infrared rays generated in a plurality of different directions. do. The lens unit 10 forms different monitoring zones for collecting infrared rays incident from different directions. To this end, the lens unit 10 includes a Fresnel lens having a plurality of lens segments having different refractive indices and forming a plurality of monitoring zones. This will be described in more detail later.

The sensing modules 11 and 12 detect infrared rays emitted from a monitoring target including a person and output corresponding electric signals. At least two detection modules according to an embodiment of the present invention, and includes an infrared sensor unit.

The infrared sensor units 112, 113, 122, and 123 of the sensing modules 11 and 12 output electrical signals corresponding to changes in the infrared light collected through the lens unit 10. A pyroelectric sensor is used here as the infrared sensor unit, but is not necessarily limited thereto. A pyroelectric element is a differential element that outputs an electrical signal when there is a temperature change, and generally does not output a signal for an object that does not move.

In an embodiment of the present invention, a first sensing module 11 and a second sensing module 12 are included, and three or more sensing modules may be included.

In the first and second sensing modules 11 and 12, the two infrared sensor units 112, 113, 122, and 123 are arranged such that the light receiving surfaces receiving the light from the lens unit 10 are positioned in different directions.

2 is a sectional view showing a sensing module according to an embodiment of the present invention. 2 illustrates the structure of the first sensing module 11 as an example.

As shown in FIG. 2, the first sensing module 11 according to the exemplary embodiment of the present invention has an infrared ray in which infrared sensor units 112 and 113 are incident from the lens unit 10 at the rear end of the incident surface of the lens unit 10. It is arranged so that each can receive. At this time, each infrared sensor unit is disposed in the form of a predetermined angle with respect to the front of the lens unit 10. In detail, the infrared sensor unit 112 is positioned at a position where the center point of the corresponding light receiving surface forms a set angle (for example, 72.4 °) with the center line A, so that an angle capable of detecting infrared rays, that is, a sensing angle is predetermined. Disposed at an angle (eg, 135 °). The other infrared sensor unit 113 is also positioned at a position where the center point of the light receiving surface forms a set angle (for example, 72.4 °) with the center line A so that the sensing angle is a predetermined angle (for example, 135 °). Is placed. Accordingly, the total detection angle that can be monitored by the two infrared sensor units 112 and 113 is formed at 270 °. Here, the center line represents a line passing through the center point of the lens unit 10 in front of the lens unit 10, that is, in front of the lens unit 10 facing the surveillance area.

As such, the first sensing module 11 includes a first infrared sensor unit 112 with the light receiving surface facing in the first direction and a second infrared sensor unit 113 with the light receiving surface facing in the second direction, where the first The center point of the light receiving surface of the first infrared sensor unit 112 facing in the direction and the center point of the light receiving surface of the second infrared sensor unit 113 facing in the second direction form a preset sensing angle. 112 and the second infrared sensor unit 113 is disposed. Accordingly, the first sensing module 11 may form an optimal sensing angle to comprehensively detect the surveillance area.

3 is a graph illustrating a sensing angle of a sensing module according to an exemplary embodiment of the present invention.

As illustrated in FIG. 3, one infrared sensor unit according to an embodiment of the present invention forms a sensing angle (for example, 135 °), so that the sensing modules 11 and 12 have a sensing angle of the total wide angle (for example, 270 °).

Similar to the first sensing module 11, the second sensing module 12 according to the exemplary embodiment of the present invention may have the first infrared sensor unit 122 having the light receiving surface facing in the first direction and the light receiving surface facing in the second direction. And a second infrared sensor unit 123, wherein a center point of the light receiving surface of the first infrared sensor unit 122 facing the first direction and a center point of the light receiving surface of the second infrared sensor unit 123 facing the second direction are included. The first infrared sensor unit 122 and the second infrared sensor unit 123 are disposed to form a preset sensing angle.

The first sensing module 11 and the second sensing module 12 according to the embodiment of the present invention having such a structure may be disposed above and below the center line of the hot wire sensing device, respectively.

4 is an exemplary view illustrating a layout view of first and second sensing modules according to an exemplary embodiment of the present invention.

As illustrated in the accompanying FIG. 4, in the embodiment of the present invention, the first sensing module 11 is disposed on the top of the center line B of the heating wire sensing device 1, and the second sensing module 12 is disposed. May be disposed at a lower end of the hot wire detecting apparatus 1 based on the center point B of the heat ray detecting apparatus 1 to monitor the monitoring areas corresponding to different positions.

The first sensing module 11 and the second sensing module 12 respectively detect infrared rays generated in the monitoring area at a sensing angle of 270 ° and output corresponding electric signals. In particular, in the embodiment of the present invention, the first sensing module 11 detects infrared rays received through the first monitoring zone through the lens unit 10 in the surveillance area, and outputs a corresponding signal. 12 detects the infrared rays received through the second monitoring zone through the lens unit 10 in the monitoring area and outputs a corresponding signal.

The first surveillance zone and the second surveillance zone according to the embodiment of the present invention may be formed by the lens unit 10, and the first surveillance zone and the second surveillance zone may be formed in a different arrangement structure for each region in the surveillance region. .

5 is an example showing a monitoring zone formed by the lens unit according to an embodiment of the present invention, Figure 6 is an exemplary view showing the shape of the lens unit according to an embodiment of the present invention.

6, when the surveillance region is divided into the first surveillance region R1 and the second surveillance region R2, the first surveillance zone Z1 and the second surveillance zone formed by the lens unit 10 are provided. Z2 is formed to be parallel to each other in the first monitoring region R1, and is formed to be alternately arranged in the second monitoring region R2.

Specifically, in the first monitoring region R1, the first monitoring zone Z1 is formed at the first height and the second monitoring zone Z2 is formed at the second height lower than the first height, but the second monitoring region ( In R2), the first monitoring zone Z1 and the second monitoring zone Z2 are alternately positioned for each position. For example, in the second monitoring region R2, the first monitoring zone Z1 is formed at the third height, the second monitoring zone Z4 is formed at the fourth height, and then again the second monitoring zone ( Z2) is formed and the first monitoring zone Z1 is formed at the fourth height so that the first monitoring zone Z1 and the second monitoring zone Z2 are alternately formed.

In this manner, the first and second monitoring zones Z1 and Z2 are formed in the monitoring area, and the first sensing module 11 outputs a signal corresponding to the light condensed by the first monitoring zone Z1. The second sensing module 12 outputs a signal corresponding to the light condensed by the second monitoring zone Z2.

To this end, as illustrated in FIG. 6, the lens unit 10 includes a Fresnel lens including a plurality of lens segments to collect infrared rays generated in different directions. For example, the first lens segments A to F are infrared rays generated from the first surveillance zone Z1 and the second surveillance zone Z2 formed in the first surveillance region R1 as illustrated in FIG. 5. The second lens segment (G, I, K) collects infrared rays generated in the first monitoring zone (Z1) in the second monitoring region (R2), and the third lens segment (H, J) is made of In the surveillance area R2, infrared rays generated in the second surveillance zone Z2 are collected.

As described above, the first and second monitoring zones Z1 and Z2 for collecting infrared rays generated at different positions are formed by the lens unit 10.

Meanwhile, the signal processor 20 according to an embodiment of the present invention processes the electrical signals output from the sensing modules 11 and 12 and outputs a corresponding sensing signal to the determination unit 30. That is, the first signal processing unit 21 processes the signal output from the first sensing module 11 to output the first sensing signal, and the second signal processing unit 22 is output from the second sensing module 12. The signal is processed to output a second detection signal.

As shown in FIG. 2, the signal processing units 21 and 22 may be disposed at the lower end of the infrared sensor unit of each sensing module to easily receive and process a signal output from the infrared sensor unit.

The determination unit 30 determines whether an intrusion has occurred in the monitoring area based on the detection signal output from the signal processing unit 20, and transmits the determination result to the control center (not shown) through the communication unit 40 or the portable terminal of the administrator. To send. Alternatively, an optional warning signal may be output through warning means (not shown).

In particular, the determination unit 30 according to the embodiment of the present invention outputs the first detection signal corresponding to the first detection module 11 output from the first signal processing unit 21 and the second signal processing unit 22. The second detection signal corresponding to the second detection module 12 is combined to determine whether an intrusion occurs. In detail, the determination unit 30 determines that an invasion occurs when the first monitoring zone Z1 and the second monitoring zone Z2 are detected at the same time, and the first monitoring zone Z1 and the second monitoring zone Z2. If only one detection is performed, dual sensing is performed to determine that no intrusion occurs. To this end, the determination unit 30 outputs a first detection signal for the first monitoring zone Z1 by the first sensing module 11 and a second monitoring zone Z2 by the second sensing module 21. When the second detection signal is outputted, it is determined that the intrusion has occurred by an intruder such as a person. However, when only the first detection signal is output from the first detection module 11 or only the second detection signal is output from the second detection module 21, it is determined that the signal is generated by an animal such as a pet. I do not think it is an intrusion.

In the embodiment of the present invention, as illustrated in FIG. 5, when a person enters the surveillance region while the first surveillance zone Z1 and the second surveillance zone Z2 are formed in the surveillance region, It is located in both the first monitoring zone (Z1) and the second monitoring zone (Z2), so that the first sensing module 11 and the second sensing module 12 simultaneously output the first sensing signal and the second sensing signal, respectively. do.

However, when pets such as dogs enter the surveillance zone, they are usually smaller than humans, so they are only detected in one surveillance zone. For example, when the animal is located on the floor, for example, only the second monitoring zone Z2 is detected in the second monitoring zone R2, and when the animal is located at a predetermined height such as a sofa, the first monitoring zone Only detected at (Z1). Therefore, when the first detection signal and the second detection signal are simultaneously output, the determination unit 30 determines that a person has invaded, and when only one of the first detection signal or the second detection signal is output, the animal is detected. It judges that it is not an invasion. Accordingly, unnecessary response processing can be prevented from occurring due to a false intrusion warning by an animal such as a pet left alone indoors.

You can also easily detect when an intruder leans over. Specifically, when the first surveillance zone Z1 and the second surveillance zone Z2 are not arranged in the second surveillance region R2 but arranged in the same form as the first surveillance region R1, a human body If it moves down, it is detected only in the monitoring zone located at the bottom, for example, the second monitoring zone (Z2). In such a case, it is likely that the target is not a human because it is detected only in one monitoring zone. However, according to an exemplary embodiment of the present invention, since the first monitoring zone Z1 and the second monitoring zone Z2 are alternately arranged in the second monitoring region R2, even when a person invades and moves, As the signals according to the detection are output from the first monitoring zone Z1 and the second monitoring zone Z2, it is possible to easily detect whether an intrusion is detected by determining that the detected target is a human. In this case, the first monitoring zone Z1 and the second monitoring zone Z2 may be alternately arranged on the basis of the height considering the case where the person is bowed down in the second monitoring region R2. Accordingly, when the signals from the sensing modules 11 and 12 are simultaneously output or respectively output within the set time, it is determined that the person is a person. Can be.

The heat ray detection apparatus 1 according to the embodiment of the present invention having such a structure may be implemented in a table type.

7 is an external perspective view of a heat ray detection apparatus according to an embodiment of the present invention.

For example, as illustrated in FIG. 7, the heat ray detection apparatus 1 according to the embodiment of the present invention may be implemented in a table type that can be installed on a desk, or the like. Accordingly, it is possible to easily and easily install a hot wire detecting device in a desired area without drilling or wiring work for installing on a ceiling or a wall.

Looking at the detection method using a heat ray detection device having such a structure, as follows.

8 is a flowchart illustrating a sensing method according to a heat ray sensing apparatus according to an embodiment of the present invention.

When the monitoring target enters the surveillance region while the heating apparatus 1 according to an embodiment of the present invention is placed on a desk positioned in the surveillance region, for example, the heating apparatus 1 may be configured as a first sensing module. 11 and the second sensing module 12 operate to detect infrared rays emitted from the monitoring target and output electrical signals corresponding thereto.

The signal processor 30 processes signals output from the sensing modules 11 and 12 and outputs a first sensing signal and a second sensing signal corresponding thereto when infrared rays having a predetermined value or more are detected (S100 and S110). ).

The determination unit 30 outputs the first detection signal indicating that a predetermined object is detected in the first monitoring zone Z1 by the first detection module 11 (S120). In the second monitoring zone Z2, it is determined whether a second detection signal indicating that a predetermined object is detected (S130). Even when the first detection signal is not output, it is determined whether the second detection signal is output.

As a result of the determination, when the first detection signal indicating that the predetermined object is detected in the first monitoring zone Z1 is output, and the second detection signal indicating that the predetermined object is detected in the second monitoring zone Z2 is output, It is determined that the detected (S140). In this case, it is determined that an invasion has occurred by a person, and the processing operation according to the invasion occurs, for example, the determination unit 30 transmits the intrusion occurrence to the control center (not shown) through the communication unit 40 or the administrator. Send to the mobile terminal.

On the other hand, when a first detection signal indicating that a predetermined object is detected in the first monitoring zone Z1 is output, but a second detection signal indicating that a predetermined object is detected in the second monitoring zone Z2 is not output, For example, it is determined that a pet such as a dog is detected (S150). In this case, the processing operation according to the intrusion is not performed.

When the first detection signal and the second detection signal are not output, it is determined as an undetected state in which no target enters the surveillance area (S160).

Through this process, it is possible to effectively prevent the detection of intrusion by detecting an object except a person such as a pet.

In the above embodiment, the hot wire detection apparatus performs a process of determining whether a person is detected or an object except a person based on signals detected in the plurality of monitoring zones, but the detection is performed in the monitoring zone without performing such a determination process. The signal can be transmitted to the control center or the portable terminal of the manager via the communication unit. Since this process can be implemented based on the above embodiment, a detailed description thereof will be omitted.

The embodiments of the present invention are not limited to the above-described apparatuses and / or methods, but may be implemented through a program for realizing functions corresponding to the configuration of the embodiment of the present invention, a recording medium on which the program is recorded And such an embodiment can be easily implemented by those skilled in the art from the description of the embodiments described above.
