Description

TECHNICAL FIELD The present invention relates to an adaptive wildlife prevention apparatus and method,

The present invention relates to an adaptive wildlife elimination apparatus and method, and more particularly, to an adaptive wildlife elimination apparatus and method using at least two infrared heat sensors (PIR) and a light intensity sensor, And more particularly, to an apparatus and method for detecting and eradicating a malfunction.

Conventionally, a thermal sensor (PIR) is generally added to a control board to detect an amount of change in infrared rays caused by an infrared ray (for example, 10 micrometer wavelength) emitted from an animal within a detection range and a temperature difference around the animal, Respectively. However, when one of these heat sensors is used to discriminate the presence of an animal, the difference between the appearance of wild animals and natural phenomena due to shaking of direct sunlight, wind, trees or reeds when the heat sensor is installed in the outdoors It can not be clearly distinguished and can cause malfunction of the sensor.

As an alternative to such a thermal sensor, there is a motion detection sensor or a camera image recognition method, but there is a problem that it is more expensive than a thermal sensor.

Also, it is possible to consider one or more of these sensors or utilize different kinds of sensors (for example, microwave and radar), but it may be considered that the sensor is merely widened, Even if it is for outdoor use, it is used only at night, so its usability is questionable.

According to one embodiment of the present invention, when an infrared heat sensor is used to detect the intrusion of wild animals or the like (for example, a mammal, etc.), a direct sunlight-based wind Or trees, and to effectively utilize the infrared characteristics of warm-blooded animals such as mammals.

In one embodiment of the present invention, an adaptive wildlife elimination device is provided for eradicating wildlife by adjusting the sensitivity of at least one thermal sensation section based on sensed illumination values. The apparatus according to an embodiment of the present invention includes a first heat sensing unit and a second heat sensing unit for sensing infrared heat, a roughness sensing unit for sensing the illuminance of the surrounding environment, a power source for power supply, And an alarm unit connected to the second sensor unit, the rough sensor unit, and the power unit and connected to the controller and the controller for adjusting the sensitivity of the first sensor unit and the second sensor unit, and generating an alarm according to a signal applied from the controller, , And the first and second heat sensing portions may be disposed in directions different from each other.

 The first heat sensing portion and the second heat sensing portion may be arranged to form a predetermined angle.

 The control unit counts the first count value obtained by counting the number of infrared ray heat sensed through the first heat sensing unit and the second count value obtained by counting the number of infrared ray heat sensed through the second heat sensing unit, And selectively adjusting the sensitivity change reference value and the detection reference value according to the illuminance value sensed by the roughness sensing section, comparing the sensitivity change reference value and the obtained difference value, By comparing the counting value and the second counting value with the detection discrimination reference value, it is possible to determine whether or not wild animals appear.

 The sensitivity change reference value can be adjusted through operation with the first coefficient based on the sensed illumination value, and the sensing reference value can be adjusted through operation with the second coefficient based on the sensed illumination value.

If the obtained difference value is greater than the sensitivity change reference value, the control unit compares the first count value and the second count value with the detection reference value, and if the obtained difference value is less than or equal to the sensitivity change reference value, The second infrared ray sensor and the second infrared ray sensor can re-detect the infrared ray heat.

There is provided an adaptive wildlife eradication method for eradicating wildlife by adjusting the sensitivity of at least one thermal sensation section based on the sensed illuminance value according to an embodiment of the present invention. The method according to an embodiment of the present invention includes the steps of sensing an infrared ray train through each of the first and second infrared ray sensor units, counting the number of times infrared ray heat is sensed through the first sensor unit as a first count value Counting the number of times infrared ray heat is sensed through the second sensor unit to obtain the second count value as a second count value, obtaining a difference value between the first count value and the second count value, Selectively comparing the sensitivity change reference value and the detection reference value according to the illuminance value, comparing the sensitivity change reference value with the obtained difference value, comparing the first count value and the second count value with the detection criterion reference value, and Determining the appearance of wild animals based on the result of the comparison, and generating an alarm when the wild animal appears.

The sensitivity change reference value can be adjusted through operation with the first coefficient based on the sensed illuminance value, and the sensing discrimination reference value can be adjusted through calculation with the second coefficient based on the sensed illuminance value.

As a result of comparison between the sensitivity change reference value and the obtained difference value, if the obtained difference value is greater than the sensitivity change reference value, the first counting value and the second counting value are compared with the detection criterion reference value, The infrared ray heat can be re-sensed by the first and second heat sensing portions.

According to another aspect of the present invention, there is provided a computer-readable recording medium storing a program for causing a computer to execute the above-described method.

According to an embodiment of the present invention, the detection range can be extended by 1/3 to 2 times as much as the conventional method by disposing the two sensor units at a predetermined angle, for example, at an angle of 45 degrees.

In the case of using two infrared ray sensitive portions, it is not always that the infrared ray amounts detected by the two sensors are similarly detected with respect to the solar-based natural disturbance, and a considerable portion can be detected only by one thermal ray portion, In order to solve the conventional problem that it is necessary to continually and insufficiently operate even in the case where it is not in the solar-related disturbance (for example, cloudy weather or nighttime) It is possible to precisely detect the appearance of a wild animal or the like without regard to time or environment by inducing the heat sensitive portion to act dullly or sensitively in accordance with the presence or absence of direct sunlight by adaptation .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a conventional wildlife eradication apparatus. Conventional wildlife suppression devices have utilized a method of detecting the appearance of an animal by detecting the amount of infrared rays due to the difference in temperature between the infrared rays emitted from an animal and the ambient temperature within a detection range using one thermal sensation unit. However, when using only one heat sensitive portion as in the conventional technique, it is impossible to clearly distinguish between the detection by the natural phenomenon such as the direct sunlight (for example, sunlight), the wind, the shaking of the tree / reed, There is a problem that an alarm can be generated by recognizing an animal as an appearance. [0005] As an alternative method to solve such a problem, there is a method using a motion detection sensor or a camera image recognition method, There is a problem that an animal appearance detection error may occur more frequently and it may be costly.

Another alternative is to use two hot-sensed parts, and the infrared sensed value that reacts to natural phenomena such as direct sunlight, wind, shaking of trees or reeds, In most cases, it is possible to distinguish and remove the disturbance of the sun because it is measured at a similar level and widely applied to the attached sensor. However, it is necessary to carry out the continuous sensing operation with the degree of sensitivity (or the sensitivity of the heat sensitive portion) Even if different sensors such as a microwave and a radar are used, the conventional method and apparatus for exterminating wild animals can be limited to indoor use only, , The problem that it is not available for both daytime and nighttime The.

Accordingly, it is possible to solve the problems of the above-described conventional wildlife prevention apparatus and method by using the wildlife suppression apparatus and method using at least two heat sensing units and one roughness sensing unit according to an embodiment of the present invention. This will be described later with reference to Fig.

2 is a block diagram illustrating an adaptive wildlife elimination apparatus in accordance with an embodiment of the present invention.

In one embodiment of the present invention, an adaptive wildlife elimination device is provided for eradicating wildlife by adjusting the sensitivity of at least one thermal sensation section based on sensed illumination values. The apparatus 100 according to an embodiment of the present invention includes a first heat sensing unit 110 and a second heat sensing unit 130 for sensing infrared heat, a roughness sensing unit 120 for sensing the illuminance of the surrounding environment, A control unit 140 connected to the power supply unit 150 for supplying power, the first and second heat sensing units, the second heat sensing unit, the roughness sensing unit, and the power supply unit and for adjusting the sensitivity of the first and second heat sensing units, And an alarm unit 160 connected to the first sensor unit 110 and generating an alarm according to a signal applied from the control unit. The first sensor unit 110 and the second sensor unit 130 may be disposed in different directions.

The power supply unit 150 can supply power to the first heat sensing unit 110, the rough sensing unit 120, the second heat sensing unit 130, the control unit 140, and the alarm unit 160.

The first heat sensing unit 110 and the second heat sensing unit 130 can detect the infrared heat input from the outside through the heat sensing sensor and output the sensed infrared heat sensing value.

The first heat sensing part 110 and the second heat sensing part 130 may be arranged to form a predetermined angle. The first sensor unit 110 and the second sensor unit 130 may be arranged in parallel to each other in the horizontal direction. However, as in the embodiment of the present invention, the first sensor unit 110 and the second sensor unit 130 may be arranged to form a predetermined angle, have. For example, the first heat sensing unit 110 and the second heat sensing unit 130 may have an angle between a range of angles of 90 degrees to 108 degrees. Preferably the angle of intersection can be 90 degrees.

The roughness sensing unit 120 may be referred to as an illuminance sensor, and may sense light input from the surrounding environment and output an illuminance value corresponding to the brightness of the sensed light.

The control unit 140 counts the first count value obtained by counting the number of times of infrared ray heat detection through the first temperature sensor unit 110 and the second count value obtained by counting the number of infrared ray heat detection through the second temperature sensor unit 130, Value, the difference value between the first count value and the second count value can be obtained. The control unit 140 selectively adjusts the sensitivity change reference value and the detection reference value according to the illuminance value sensed by the roughness sensing unit 120, compares the sensitivity change reference value with the obtained difference value, And comparing the second counting value with the detection criterion reference value, it is possible to determine whether or not a wild animal appears.

At this time, the sensitivity change reference value can be adjusted through calculation with the first coefficient based on the sensed illuminance value, and the detection discrimination reference value can be adjusted through calculation with the second coefficient based on the sensed illuminance value.

If the obtained difference value is greater than the sensitivity change reference value, the controller 140 compares the first count value and the second count value with the detection reference value, and if the difference value is smaller than the reference value The first heat sensing unit 110 and the second heat sensing unit 130 can cause the infrared rays to be re-sensed.

The alarm unit 160 may generate an alarm according to a signal applied from the control unit 140. The alert form can be of any form if it is capable of raising awareness of wildlife or practically eliminating wildlife, including wild animal cries, gunshots, sirens, and flashing flashes at night And may be of a type that emits light brightly. In addition, the alarm unit 160 may include a robot arm, a fan, an actuator, or the like as an alarm auxiliary mechanism, and the type of the alarm may be a motion of the robot arm, a fan or an actuator, Generation, and the like.

3 is an embodiment of an adaptive wildlife elimination apparatus according to an embodiment of the present invention.

The adaptive wildlife elimination apparatus 100 according to an embodiment of the present invention includes a first heat sensing unit 110 and a second heat sensing unit 130, a roughness sensing unit 120, a power source unit 150, an alarm unit 160, And the first heat sensing unit 110 and the second heat sensing unit 130 may be disposed to face each other in a different direction. The infrared ray heat detection values of the first and second hot-spot detectors 110 and 130 are not greatly different from each other when infrared rays are detected by the sun. When the animal appears, the first sensor unit 110 and the second sensor unit 130 are disposed in different directions from each other, so that the first sensor unit 110 and the second sensor unit 130 are similar to each other It is very unlikely to detect infrared thermal sensed values in the range. According to an embodiment of the present invention, the first and second heat sensing units 110 and 130 may be operated in a dull or sensitive manner according to the illuminance value sensed by the rough sensing unit 120 The appearance of wild animals can be detected more precisely and effectively without being affected by the surrounding environment such as the sensing time or the weather by sensing the infrared rays of the first and second hot-sensing units 110 and 130.

4 is a flowchart illustrating an adaptive wildlife eradication method according to an embodiment of the present invention.

There is provided an adaptive wildlife eradication method for eradicating wildlife by adjusting the sensitivity of at least one thermal sensation section based on the sensed illuminance value according to an embodiment of the present invention. The method according to an embodiment of the present invention includes the steps of sensing infrared rays through each of the first and second infrared sensor units S1000 and S1000, counting the number of times infrared ray heat is sensed through the first sensor unit, (S2000) of counting the number of times of infrared ray heat detection through the second hot-spot portion as a second count value (S2000), acquiring a difference value between the first count value and the second count value (S3000) (S5000) of selectively adjusting the sensitivity change reference value and the detection reference value according to the sensed illumination value (S5000), comparing the sensitivity change reference value with the obtained difference value, and setting the first count value (S6000) comparing the second count value with the detection reference value (S6000), determining whether the wild animal appears on the basis of the comparison result, and generating an alarm when the wild animal appears (S7000) .

The sensitivity change reference value according to an exemplary embodiment of the present invention can be adjusted through operation with the first coefficient based on the sensed illuminance value, and the sensing discrimination reference value is calculated through the operation with the second coefficient based on the sensed illuminance value Can be adjusted. By adjusting the magnitude of the first coefficient and the second coefficient, the degree of sensitivity of the sensor becomes insensitive as the magnitude of the sensing change reference value and the sensing discrimination reference value becomes larger, and the sensing degree of the sensor becomes more sensitive as the magnitude of the sensing change reference value becomes larger. Here, the value of each coefficient may have a value in the range of 1.0 to 3.0, and it may be most appropriate to determine the magnitude corresponding to the illuminance value.

As a result of comparison between the sensitivity change reference value and the obtained difference value, if the obtained difference value is greater than the sensitivity change reference value, the first counting value and the second counting value are compared with the detection criterion reference value, The infrared ray heat can be re-sensed by the first and second heat sensing portions.

5 is an embodiment of an adaptive wildlife eradication method according to an embodiment of the present invention.

According to an embodiment of the present invention, infrared heat can be sensed through the first heat sensing unit 110 and the second heat sensing unit 130, respectively. For example, it is possible to perform 100 thermal senses per 1000 ms, which is 1 second. The infrared heat sensed value sensed through each of the first sensor unit 110 and the second sensor unit 130 may be sensed by a first memory unit (E.g., buffer 1) and a second memory unit (e.g., buffer 2). For example, when a row is stored in a buffer unit having a size of 100, a value of 1 is stored in the buffer when a row is sensed by the row sensor, and a value of 0 may be stored in the buffer when the row is not sensed (S1000) . The first memory unit and the second memory unit may be present in the control unit 140 or may be connected to the control unit 140 as a separate storage unit (not shown).

The control unit 140 may obtain the first count value by counting the infrared ray sensed value sensed by the first sensor unit 110 and stored in the first memory unit (S2001). In addition, the control unit 140 can obtain the second count value by counting the infrared ray sensed value sensed by the second sensor unit 130 and stored in the second memory unit (S2002). In other words, a value of 1 or 0 may be stored in the first memory unit or the second memory unit depending on whether the infrared ray string sensed by the heat sensing unit 110 or 130 is changed. In the control unit 140, And counts the number of 1's stored in the second memory unit, thereby detecting whether the infrared ray column is changed by the thermal sensation unit. The number of 1s stored in the first memory unit or the second memory unit may indicate the number of times the infrared ray changes.

The controller 140 may store the acquired first count value and the second count value in the variables sensor 1_sum and sensor 2_sum, respectively. The variables sensor 1_sum and sensor 2_sum indicate the degree of heat sensed by the first and second sensor units 110 and 130 and the size of the sensor 1_sum / buffer (buffer_size) And the size of the sensor 2_sum / buffer may indicate the thermal sensitivity of the second thermal sensor 130.

In step S3000, the difference value between the first count value and the second count value can be obtained. For example, the difference value can be obtained by calculating the absolute value of (sensor 1_sum-sensor 2_sum). The obtained difference value can be assigned to the variable differ.

The illuminance of the surrounding environment can be detected by the rough image sensing unit 120. [ The sensed illumination value can be classified into Levels, for example, 1 to 10 (S4000). For example, the illuminance value can be classified to have any one of the levels of 1 to 4 in the day, 5 to 6 in the cloudy day, and 7 to 10 in the night, but the present invention is not limited thereto.

In step S5001, the input illumination value and the sensitivity change reference value can be compared. For example, if the illuminance value is classified as 1 to 4 in the daytime, 5 to 6 in the cloudy day, and 7 to 10 in the nighttime, as described above, the initial sensitivity change reference value is set to 5, If it is small, it is determined that the sunlight exists in the daytime, and the process proceeds to step S6000. In step S6000, the difference value and the sensitivity change reference value may be compared (S6001) or the difference value may be compared with the detection reference value (S6002).

If the sensitivity change reference value is greater than the sensed illumination value in the above example, the controller 140 determines that the surrounding environment of the roughness sensing unit 120 is blurry or at night and sets the sensitivity change reference value based on the sensed illumination value. 1 coefficient, and the detection criterion reference value can be adjusted through calculation with the second coefficient based on the sensed illumination value (S5002). Therefore, by comparing the difference value with the adjusted sensitivity change reference value or the difference value and the adjusted detection reference value, it is possible to accurately determine the appearance of wild animals by keeping the value of each sensor sensitively at night or at night (S6000).

In other words, by varying the size of the sensitivity change reference value and the detection determination reference value to be compared with the thermal sensed values of the first or second thermal sensor unit 110 or 130 according to the sensed illumination value, In the present day, the sensor is relatively insensitive, and on a cloudy day or night, the sensor is sensitized, so that the appearance of wild animals can be accurately detected regardless of the surrounding environment.

In step S6001, the controller 140 compares the sensitivity change reference value with the difference value assigned to the variable difference. If the difference is less than or equal to the sensitivity change reference value, the first and second hot- If the difference value is greater than the sensitivity change reference value, the flow advances to step S6002 to compare the first count value or the second count value with the detection reference value.

If it is determined that the first count value or the second count value is less than the detection determination reference value, the controller 140 determines that the wild animal does not exist and the first and second heat sensing units 110 and 130 If it is determined that the first counting value or the second counting value is greater than or equal to the detection discrimination reference value, then it is determined that wild animals have appeared in the infrared heat sensing range (S7001) 160 to generate an alarm (S7002).
