The damage of farmland and fruit crop crops caused by harmful tides continues to increase.

Due to the improvement of habitat environment such as forest greening and forest cultivation business, the number of wild tide is increasing greatly. With the destruction of food chains due to the extinction of predators and the reduction of raptors, the number of harmful tides such as wild boar magpies is increasing rapidly. The domestic wild boar population density surveyed by the National Institute of Biological Resources in 2014 was 4.3 per 100 hectares, an increase of 0.8 compared to 3.5 in 2010, and the density of elk was 8.2 per 100 hectares. .

The damages amounted to KRW 5.4 billion for five years in Chungbuk alone, KRW 12.3 billion in 2010, KRW 15.5 billion in 2011, KRW 12.3 billion in 2012, KRW 12.7 billion in 2013, and KRW 10.9 billion in 2014. These are only official statistics, and the actual amount of damage and mental stress that farmers feel is not countable.

Hazardous tide damages crops such as apples, corn, and sweet potatoes in Chungbuk province.

Hazardous tide damage increases the risk of high-potential and high-influence legal epidemics caused by direct and indirect contact between crops and livestock. Most of the AIs that occur every year are caused by wild tides such as migratory birds.

The damage caused by the increase in the number of harmful tides continues to increase, and is still serious and will increase further. Therefore, a solution is necessary.

Existing tidal control systems include:

■ The most common method used to combat wild birds is electric fences. Three rows of 25cm high to 25cm apart from the ground are used to send electricity to areas and seasons where wild tides often appear. When boars are frequently inhabited, the usage of the electric tree tool varies depending on the characteristics of the wild animals, such as sending electricity to the bottom two lines and when the elk appears. However, there are disadvantages such as installation cost, electric charge, risk of electric shock, troublesome after-care such as failure.

■ Scientific verification of tiger feces, grass vinegar, garlic, hair, and chemicals (cymetic agents, carbohydrates, naphthalene, etc.) that are used as repellents of wild animals such as wild boar in general farms. Only a temporary effect of degree is confirmed.

■ The Bird Research Institute has developed a drug to reduce the willingness and propagation effect of re-invasion when the magpie is eaten, but criticism of animal abuse is being raised.

■ Reproductive environment management, which provides habitat for wildlife to avoid inhabitants, and ways to adequately reduce populations by capturing or hunting permits. Only 72,779 wild animals have been captured nationwide in the last five years. But damage is still occurring.

■ The system of combating harmful tides by using the sound and sound waves of the fixed device is only effective within a certain area, and has the problem of adapting harmful tides over time.

■ The method of blocking the invasion of harmful tidal water by wrapping the whole fruitland and farmland is effective, but the netting is very expensive to install and damages the fruitage and farmland facilities in case of heavy wind or snow. Can only be used for one year.

■ There are also extermination devices using sensors. A method of randomly generating sounds or surprising them through light is used as a combat sound.

Despite many attempts using existing tidal control systems, damage is still occurring. This is because harmful tides are initially effective due to alertness to new objects or the environment, but there is a limit to their effectiveness diminishing or disappearing due to adaptation to repeated threats.

The embodiment proposes an AI eradication system that prevents the adaptation of harmful tides by using AI technology.

Hereinafter, an artificial intelligence eradication system for preventing adaptation of harmful tides according to an embodiment will be described.

1 is a conceptual diagram for explaining an artificial intelligence harmful tide erasing method according to an embodiment, Figure 2 is a schematic block diagram of an artificial intelligence harmful tide elimination apparatus according to an embodiment.

The harmful tide elimination device 10 detects intrusion of harmful tide at a place indicated by the harmful tide, for example, farmland, fruit land, airport, etc., and eliminates the harmful tide.

The harmful tidal control apparatus 10 is a combination of a technique for detecting an invasion of a harmful tidal wave, a technique for analyzing the behavior of a harmful tidal wave, a technique for determining a response technique (including eradication) against a harmful tidal wave, and a technique for combating a harmful tidal wave. It can be implemented through.

The harmful tidal current elimination device 10 includes a sensor 110, a controller 130, a repeller 150, and a power device 170.

The sensor 110 may detect harmful tides. For example, the sensor 100 may sense an object and output a sensing value to the controller 130.

For example, the sensor 110 may include an ultrasonic sensor and a PIR sensor. As another example, the sensor 110 may include a camera sensor. As another example, the sensor 100 may include an ultrasonic sensor, a PIR sensor, and a camera sensor.

The controller 130 may control the overall operation of the harmful tidal control apparatus 10. For example, the controller 130 may control operations of the components 110, 150, and 170.

The controller 130 may detect an intrusion of a harmful address by using the sensing value sensed by the sensor 110. For example, the controller 130 may detect an intrusion of harmful tides through a distance based detection technology. As another example, the controller 130 may detect an intrusion of the harmful tidal through a camera sensor-based harmful detection technology (Moar Detection Technology, haar-based Learned Object Detection Technology). As another example, the controller 130 may detect an intrusion of the harmful tidal water by using one or more of a distance based detection technology and a camera sensor based harmful tidal wave detection technology.

When the controller 130 detects the intrusion of the harmful tides, the controller 130 may eliminate the harmful tides by outputting a repelling sound based on the return time and the end time of the harmful tides. For example, the controller 130 may output a combat sound that reflects a compensation value according to a return time and an endurance time of the harmful tides. Through this, the controller 130 can prevent the adaptation of the harmful tidal to the combat sound.

The return time may be a time from the eradication time to the time when the harmful algae are detected again, and the endurance time may mean a time when the extinguishing sound is output (or regenerated) within the protection area and does not escape.

In addition, the controller 130 may control the output volume of the combat sound by comparing the previous return time and the current return time of the harmful tides. For example, the controller 130 may increase the output size of the eradication sound when the harmful tide is shortened, and decrease the output magnitude of the eradication sound when the harmful tide is long.

The repeller 150 may output a repellent sound under the control of the controller 130. The repellent 150 may include a speaker capable of outputting a repellent sound.

The power device 170 may provide power (or a power source) to the noxious tidal control device 10. As shown in FIGS. 3 and 7, the power device 170 may be comprised of a solar panel, a battery, and a charge controller.

FIG. 3 shows an example of an apparatus for combating harmful tides based on Distance based Detection Technology, FIG. 4 shows characteristics of a PIR sensor utilized in Distance based Detection Technology, and FIG. 5 shows characteristics of an ultrasonic sensor utilized in Distance based Detection Technology. 6 is an example of implementation of a harmful tidal current control apparatus based on a Distance based Detection Technology installed in a real environment.

The harmful tide eliminating device 10 may detect an intrusion of the harmful tides through the distance based detection technology. The distance based detection technology may be a technology for determining whether there are harmful tides in the range by measuring a distance value with an object invading through one or more sensors.

In order to implement the distance based detection technology, the sensor 110 may include an ultrasonic sensor 111 and a PIR sensor 113.

The PIR sensor 113 has a wide detection range. The wide characteristic of the detection range of the PIR sensor 113 can be confirmed in the detection range of the PIR sensor 113 shown in FIG. 4.

The ultrasonic sensor 111 may detect an invasion occurring at various angles due to various detection angles. This characteristic of the supersonic wave sensor 110 can be seen in FIG. 5.

The controller 130 may detect the harmful tidal water by using the sensing values of the ultrasonic sensor 111 and the PIR sensor 113.

Detection techniques based on distances such as the ultrasonic sensor 111 and the PIR sensor 113 can detect intrusion of all objects occurring within a specific range.

Through this, the intrusion detection reaction speed of the controller 130 is fast. In addition, no extra post-processing is required, so intrusions can be detected without requiring additional hardware performance.

In FIG. 6, an example of implementation of an apparatus for combating harmful tides based on a Distance based Detection Technology installed in a real environment can be confirmed. (a) is the inside of the harmful tidal current control device 10 based on the Distance based Detection Technology, (b) is the actual module installed in the feed container inside the kennel experiment environment, and (c) the module is installed outside the feed container. It is to try to detect through PIR sensor. (d) shows the practical configuration of the detection module for use in a real environment using a solar panel and a cradle.

The retirement 150 shown in FIG. 3 illustrates an implementation of an MP3 player, an amplifier, and a speaker.

FIG. 7 illustrates an example of an apparatus for combating harmful tides based on a technique of detecting harmful tides using a camera sensor, and FIG. 8 illustrates an example of an apparatus for combating harmful tides based on a technique for detecting harmful tides using a camera sensor installed in a real environment.

The harmful tidal control apparatus 10 may detect an intrusion of the harmful tidal current through a camera sensor-based harmful detection technology (Moar Detection Technology, haar-based Learned Object Detection Technology).

In order to implement a camera sensor based harmful tide detection technology, the sensor 110 may be configured as a camera sensor 115.

The controller 130 may detect a harmful tidal water using a sensing value (eg, image data) of the camera sensor 115.

The controller 130 may detect a harmful tidal water by performing a motion detection technology (MD) and a haar-based learned object detection technology (hLOD).

Motion detection technology may be a technology for identifying and detecting moving objects in the image data of the camera sensor 115. Moving objects in the image data were identified through the OpenCV library, and the minimum detection constants for identifying harmful tides were obtained through experiments.

The haar-based learned object detection technique may be a technique for detecting when an object learned by the user appears in the image data of the camera sensor 115. Images of harmful birds (magpies, direct beaks, and chicks) can be trained by computers and detected by extracting feature points and comparing them with image data. To do this, you must learn first. By creating a cascade file that extracts feature points through training, the actual memory required for detection is less than that of motion detection technology, and it can accurately detect the learned object.

The retirement 150 shown in FIG. 7 illustrates that the Bluetooth speaker is implemented.

9 and 10 are views for explaining a harmful tidal current prevention prevention technology.

The controller 130 may perform an artificial intelligence harmful tide prevention prevention technology. For example, the controller 130 may perform at least one of the Fixed Reinforcement Strategy algorithm and the Autonomous Reinforcement Strategy algorithm to combat the harmful tide adaptation prevention.

The Fixed Reinforcement Strategy algorithm is to prevent adaptation of harmful birds. It is to evaluate the threat level for the sound of eradication that AI must judge through separate experiments and operate the eradication algorithm based on this.

The Fixed Reinforcement Strategy algorithm starts by sorting all sounds in relative order, starting from the least effective sound to the most effective sound, and reproducing the weakest sound when the first algae is detected. And if the tidal wave is not eliminated, it contains a simple routine that plays a stronger sound step by step, and if the tidal wave is not intruded or detected until the previous return time, the sound level goes down step by step. .

Table 1 shows the Fixed Reinforcement Strategy algorithm. If a bird is detected from the sensor, line 1, the return time of the previous bird and the current return time can be calculated in line 2. The return time is the time from the elimination to the point when noxious birds are detected again. If the bird's return cycle gets shorter, it means raising the sound level and kicking the bird out with a stronger sound. In addition, in line 6 and line 4, if the cycle of returning the bird becomes longer, it means that the sound level is lowered to respond.

The Autonomous Reinforcement Strategy algorithm utilizes Reinforcement learning.

In the case of the Fixed Reinforcement Strategy algorithm, when the new sound is inserted, the threat level should be re-created. However, the Autonomous Reinforcement Strategy algorithm judges the threat level according to the response of the algae to the algae. .

Reinforcement learning is a method of choosing the behavior or sequence of actions that maximizes the reward among the selectable behaviors by rewarding the behavior as the creatures learn.

Agents can be used to combat harmful tide, sounds to combat action, and environment to protect harmful tide. Rewards can be given according to the result of the elimination to make it possible for the algorithm to be able to adapt to the tide.

Although the biggest problem of the existing eradication was the adaptation of harmful birds to sound, the controller 130 may determine the adaptation of harmful birds through variables such as return time and endurance time while collecting basic data of harmful birds. The return time is the time from the eradication to the time when the harmful algae are detected again, and the endurance time means the time when the extinguishing sound is not played within the protection area.

The Autonomous Reinforcement Strategy algorithm performed on the controller 130 may be designed as a method of repelling the agent using the reinforcement learning technique, the action using the kind of sound, the reward, the return time and the end time, and the compensation accordingly. .

10 shows the maximum compensation selection algorithm of the developed Autonomous Reinforcement Strategy algorithm and the compensation result according to the change of the detection value. (a) means that the best value function (v *) is used in Reinforcement learning to select the best value among the next situation s' predicted when reward r is rewarded according to action a in situation s. . The optimal policy (q *) means to select the action a 'which has the next best value when the reward r and the next predicted situation s' is based on situation s and action a. (b) is a graph in which the compensation result is changed according to the change of the constant that the artificial intelligence can make a new choice that cannot predict the result value.

The implementation of the algorithm uses the Q-learning technique during reinforcement learning. Where s is the current situation,

Is the following situation,

Playing of the combat sound,

Means the regeneration sound of the tide and the compensation value according to the reaction endure time and return time. The compensation value may include the output (or reproduction) magnitude and / or output time of the tonal sound.

The Autonomous Reinforcement Strategy algorithm works to find the best reward value for the purpose of finding the optimal policy and value function while the reward can be as shown in Table 3 (final compensation calculation formula of the Autonomous Reinforcement Strategy algorithm).

The harmful tide eliminating apparatus 10 according to the embodiment shows an experimental result of eliminating harmful algae up to 79% more effectively than the single pattern and random pattern used in the existing eradication. As learning time increases, graphs show more effective actions.
