  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[Configuration of Pest Fighting System]
In the present invention, pests and insects such as moles, monkeys and bears invade protected areas such as fields, and crops in the protected areas are referred to as pests and pests (hereinafter simply referred to as “harmful animals”). .) Applied to pest repelling system to prevent being devastated. For example, as shown in FIG. 1, this pest repelling system monitors a protected area such as a field by a pest monitoring / repel control device 1 (field server), and from the pest control server 5 and the information analysis server 6. Based on the information, the speaker 2, the threatening lamp 3, and the high-voltage current generator 4 are appropriately repelled. In addition, although this embodiment demonstrates the case where the pest and threat control server 5 and the information analysis server 6 are comprised separately, you may be comprised by the single server.

  The pest monitoring and repelling control device 1 is connected to the pest and threat control server 5 and the information analysis server 6 via the network NT, and actually performs a pest and threatening speaker 2, a threatening lamp 3, a high-voltage current generator 4 This controls the repelling action. A plurality of the pest monitoring / repulse control devices 1 are arranged in a protection area such as a field, and each pest monitoring / repulse control device 1 includes one or a plurality of speakers 2, a threatening lamp 3, a high-voltage current generator 4 Is connected. These speaker 2, threatening lamp 3, and high-voltage current generator 4 are each a sound emission characteristic, a lamp characteristic, the scale of the electric wires constituting the high-voltage current generator 4, and a single pest monitoring / repulse control device 1 A plurality of protection areas are arranged depending on the area of the protection area to be monitored.

  As shown in FIG. 2, the pest monitoring / repulse control device 1 displays a communication I / F 11 for performing communication via the network NT and an image of a predetermined protection area around the pest monitoring / repulse control device 1. The camera 12 to image, the moving body detection part 13, the speaker 2, the threatening lamp 3, and the drive control apparatus 14 which controls the repelling operation | movement of the high voltage current generator 4 are provided.

  The camera 12 images a predetermined area, which is a protection area of the pest monitoring / repulse control device 1 at all times, and outputs the image to the moving object detection unit 13.

  The moving body detection unit 13 detects an object having a movement among images captured by the camera 12. When the moving object detection unit 13 detects an object (moving object) that moves continuously by comparing images that move forward and backward in time, the moving object detection unit 13 outputs an image including the object to the communication I / F 11.

  The communication I / F 11 includes a detection signal indicating that an intrusion of a moving object has been detected in the protection area of the pest monitoring / repulse control device 1 when an image including the moving object is output from the moving object detection unit 13, and a moving object detection unit. Communication data including the image captured at 13 is created. Then, the communication I / F 11 sets the transmission source of the communication data as its address information, sets the transmission destination of the communication data as the address information of the pest control server 5, and transmits it to the network NT.

  In addition, the communication I / F 11 receives repelling operation information, which will be described later, from the harmful animal threatening control server 5 as a response to the transmission of the communication data including the detection signal and the image. The communication I / F 11 outputs the repelling operation information to the drive control device 14.

  The drive control device 14 keeps the speaker 2, the threatening lamp 3, and the high-voltage current generating device 4 in a stopped state at a normal time when no moving object is detected in the protection area. The drive control device 14 outputs repelling operation information from the communication I / F 11 when a moving object is detected to enter the protected area. Then, when the repelling operation information is input, the drive control device 14 causes the speaker 2, the threatening lamp threatening lamp 3, and the high-voltage current generator 4 to be repelled by the repelling method specified by the repelling operation information. At this time, the drive control device 14 recognizes any one of the speaker 2, the threatening lamp 3 and the high-voltage current generator 4 that should be repelled from the repelling operation information, and repels it under the operating conditions such as the operating frequency of the device. A control signal for performing the operation is output.

  The speaker 2 is composed of an acoustic device that can control the start and stop of sound output by a control signal from the drive control device 14 and can output sound waves in a plurality of frequency bands. The speaker 2 generates a sound wave having a frequency that the pest avoids by a control signal from the drive control device 14. Accordingly, the speaker 2 performs a repelling operation that threatens the pest.

  The threatening lamp 3 is controlled to start and stop lighting by a control signal from the drive control device 14. Further, the threatening lamp 3 can change the light amount and the lighting frequency by a control signal from the drive control device 14. As a result, the threatening lamp 3 generates a light of a light amount or a frequency that is repelled by the pest, and performs a repelling operation to threaten the pest.

  The high-voltage current generator 4 includes a high-voltage line and a current generator installed in the protection area, and current generation start and stop are controlled by a control signal from the drive controller 14. Further, the high-voltage current generator 4 may be configured to be able to change the frequency of the current, and may be configured to cause a pulse current to flow according to a control signal from the drive controller 14. Thereby, the high-voltage current generator 4 performs a repelling operation that threatens the pest.

  Thus, the pest monitoring / repulse control device 1 and the speaker 2, the threatening lamp 3, the high-voltage current generating device 4 function as a repelling device, and the drive control device 14 of the pest monitoring / repulse control device 1 and the speaker. 2, the threatening lamp 3 and the high-voltage current generator 4 function as a harmful animal threatening means for threatening a harmful animal.

  The information analysis server 6 transmits the communication data including the detection signal and the image from the pest monitoring / repulse control device 1 via the network NT and the pest threat control server 5 to protect the pest monitoring / repulse control device 1. Identify pests that have entered the area. This information analysis server 6 includes a communication I / F 61 that communicates and connects with the pest control server 5, a pest identification unit 62 that identifies the pest from the received image, and identifies the pest by the pest identification unit 62. And a template image database 63 formed by creating a database of information to be used.

  The template image database 63 stores a template to be compared with an image transmitted from the pest monitoring / repulse control device 1 or an analysis result of the pest for each pest estimated to enter the protection area. That is, a plurality of templates such as a template for specifying that the pest is a mole and a template for specifying that the pest is a monkey are stored.

  As an example, as shown in FIG. 3, the template image database 63 takes out the light and dark parameters indicating the light and dark change for each of the three primary colors from the image data of each row of the template image indicating the characteristics of the animal ((a), (B), (c)), frequency spectrum intensities ((a) ′, (b) ′, (c) ′) obtained by Fourier transforming the shade parameters of each color are stored as templates.

  When the information analysis server 6 receives the detection signal and the image through the communication I / F 61, the pest identification unit 62 extracts the shade parameter indicating the shade change for each of the three primary colors as shown in FIG. (A), (b), (c)), and image analysis processing for obtaining frequency spectrum intensities ((a) ′, (b) ′, (c) ′) obtained by Fourier transforming the shade parameters of each color. . Then, the pest identification unit 62 determines the frequency spectrum intensity ((a) ′, (b) ′, (c) ′ in FIG. 4) for each color and a certain pest stored in the template image database 63. The frequency spectrum intensities ((a) ′, (b) ′, (c) ′ in FIG. 3) that are templates are compared, and the degree of coincidence of both frequency spectrum intensities is calculated.

  Thus, the pest identification unit 62 obtains the degree of coincidence of the frequency spectrum intensity for each pest stored in the template image database 63, and the matching ratio becomes a predetermined ratio (for example, 90%) or more. If there is, the pest is identified as being included in the image transmitted from the pest monitoring / repulse control device 1 and notified to the pest threat control server 5.

  Thus, the information analysis server 6 functions as a pest identification unit that identifies a pest included in the image.

  The pest and threat control server 5 identifies a repelling action for appropriately repelling the pest specified by the information analysis server 6 from the protected area, and monitors the pest monitoring and fighting control device 1 and the speaker 2 and the threatening lamp. 3. Control the repelling action by the high-voltage current generator 4 to perform the beast intimidation. The pest control system 5 includes a communication I / F 51 for the pest monitoring / repulse control device 1, a communication I / F 52 for the information analysis server 6, a repelling method specifying unit 53, and a repelling method database 54.

The repelling method database 54 includes, for each pest, a device of a type that the pest repels (speaker 2, threatening lamp 3, high-voltage current generator 4), a sound wave frequency band that the pest repels, the pest The light-emitting operation to avoid and the high-voltage current operation to avoid the pest are stored. For example, as shown in FIG. 5, the remission method database 54 includes a sound wave frequency band for each animal (harmful animal; A _{1 to} A _{M + 2} ) identified by the information analysis server 6 as a threatening method for the animal. F ₁ , F _{2 to} F _M , light emission operation, and high voltage current operation are stored.

  Thereby, the repelling method specifying unit 53 specifies the threatening method corresponding to the pest specified by the information analysis server 6 by the communication I / F 52 with reference to the repelling method database 54, and the repelling operation information is transmitted to the communication I / F. F51 is transmitted to the pest monitoring / repulse control device 1.

  In contrast, the pest monitoring / repulse control device 1 is driven to operate the speaker 2, the threatening lamp 3, and the high-voltage current generator 4 according to the repulse operation information when receiving the repulse operation information through the communication I / F 11. Control by the control device 14 is performed.

[Operation of Pest Repel System]
Next, an operation procedure in the pest repelling system configured as described above will be described with reference to FIG.

  According to FIG. 6, first, in step S <b> 1, the protection area is monitored by the pest monitoring / repulse control device 1, and when a moving object is detected by the pest monitoring / repulse control device 1, An image is sent from the monitoring / repulse control device 1 to the information analysis server 6. Thereby, in this step S1, the protection area using the network NT is monitored.

  Next, the information analysis server 6 compares the Fourier transform result as a template with the Fourier transform result sent from the pest monitoring / repulse control device 1 in step S2, and in step S3, the protection area It is determined whether or not it is a pest that devastates crops, etc., and the pest is identified.

  Next, in step S3, if the information analysis server 6 identifies the pest in the protected area, in step S4, the pest threat control server 5 can repel damage with sound waves from the speaker 2. Determine if it is a beast. At this time, the pest threat control server 5 reads the repelling method corresponding to the pest specified by the information analysis server 6 from the repelling method database 54, and determines whether the repelling method is a repelling method using sound waves. If it is determined by the pest control server 5 that the repelling method is based on sound waves, in step S5, the repelling operation information indicating the repelling method using the sound waves is transmitted from the pest control server 5 to the pest monitoring and repelling control. The control signal is transmitted to the apparatus 1, and a control signal is transmitted to the speaker 2 by the drive control apparatus 14 so as to emit sound waves in a frequency band that the harmful animals avoid.

  Further, in step S6 after it is determined in step S4 that it is not a harmful beast that can be repelled by sound waves, the pest threatening control server 5 determines whether or not the pest can be repelled by light emission by the threatening lamp 3. If it is possible to fight off by light emission, the process proceeds to step S7. If it is not possible to fight off by light emission, the process proceeds to step S8. In step S6, the repelling operation information indicating the repelling method by the light emission is transmitted from the pest control server 5 to the pest monitoring / repel control device 1, and the drive control device 14 causes the pest to emit the light to avoid. Thus, a control signal is transmitted to the threatening lamp 3.

  On the other hand, in step S8, the pest control server 5 determines whether or not the pest can be repelled with a high voltage current. If it can be repulsed with a high voltage current, the process proceeds to step S9. If it is not possible to fight off with current, the process is terminated. In step S9, repelling operation information indicating a repelling method using high voltage current is transmitted from the pest control server 5 to the pest monitoring and repelling control device 1, and the high voltage current generating device 4 is operated by the drive control device 14. A control signal is transmitted. On the other hand, if it is determined in step S8 that the pest cannot be repulsed by the high voltage current, it may be impossible for the information analysis server 6 to identify the pest, so for example, analysis of the next transmitted image is performed. Will be transferred to.

  In this way, the pest repelling system uses sound waves such as ultrasonic waves that have little influence on the surroundings in order to repel pests that actually exist in the protected area, and then in the order of light emission and high-voltage current. Will be executed.

[Effect of the embodiment]

Therefore, according to this pest repelling system, it is possible to automatically repel a pest in the protected area immediately by registering an optimal repelling method corresponding to the pest based on empirical rules in advance.

  Moreover, according to this pest repelling system, by registering the frequency band of the sound wave that the pest repels for each pest, it is possible to output the sound wave of the frequency band that the specified pest repels. Yes, you can surely fight off the pests.

  The above-described embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made depending on the design and the like as long as the technical idea according to the present invention is not deviated from this embodiment.
