When the threat control unit 42 reads the detection value of the load detection sensor 30j at a predetermined cycle, the threat control unit 42 compares the detection value with a reference load. Here, when a pest exists on the top plate 30k (upper surface of the main body housing), the detection value read from the load detection sensor 30j corresponds to the reference load. On the other hand, when there is a pest on the top plate 30k (upper surface of the main body housing), the load increases by the weight of the pest, so the detection value read from the load detection sensor 30j corresponds to the reference load. Disappear. By this comparison, when the presence of a pest is detected on the upper surface of the main body housing 30a, the threat control unit 42 operates the lighting device 30m, for example, blinks for a predetermined period to threaten the pest.

  According to this configuration, when the presence of a pest is detected on the upper surface of the main body housing 30 a of the main unit 30, the pest can be repelled by operating the threatening unit 44. Thereby, the situation that a pest exists on the upper surface of the main body housing 30a is suppressed, and therefore the situation where the upper surface of the main body housing 30a is soiled by the excrement of the pest and the like can be suppressed. Thereby, the situation where the normal operation | movement of the data collection device 3 is prevented can be suppressed.

  In the present embodiment, the pest detection unit 43 includes a load detection sensor 30j that detects a load acting on the upper surface of the main body housing 30a, and the threat control unit 42 is detected by the load detection sensor 30j.

Even with such a configuration, the same operations and effects as those of the above-described embodiment can be obtained.

(Second Embodiment)
FIG. 6 is a cross-sectional view schematically showing the upper structure of the main unit 30 in the data collection device 3 according to the second embodiment. The data collection device 3 according to the second embodiment is different from that of the first embodiment in that a pyroelectric sensor 30n is used as the harmful animal detection unit 43 instead of the load detection sensor 30j. The basic system configuration is the same as that of the first embodiment, and the detailed description is omitted by citing the reference numerals.

  As shown in the figure, an antenna 30 h that functions as a wireless communication unit 37 is installed on the upper part of the main body housing 30 a of the main body unit 30. In addition, a sensor mounting base 30i is provided on the upper portion of the main body housing 30a, as in the first embodiment. A pyroelectric sensor 30n is disposed at the upper center of the sensor mounting base 30i. The pyroelectric sensor 30n is a sensor that detects a temperature distribution, and an infrared sensor can be used. A top plate 30k is disposed above the pyroelectric sensor 30n. The top plate 30k has a substantially U-shaped cross section, and an opening is attached downward so as to cover the antenna 30h, the sensor mounting base 30i, and the upper part of the main unit 30. In addition, an opening (not shown) is formed in a portion of the top plate 30k that corresponds to the pyroelectric sensor 30n so that the top plate 30k does not cover the light emission and detection surface of the pyroelectric sensor 30n. The light emitting surface and the detection surface are exposed from this opening. Detection data from the pyroelectric sensor 30n is output to the threat control unit 42 shown in FIG. In other words, in this embodiment, the pyroelectric sensor 30n functions as a pest detection unit 43 (see FIG. 3) that detects the presence of a pest on the upper surface of the main body housing 30a. Although omitted in FIG. 2, the top plate 30k is provided with a lighting device 30m that functions as the threatening portion 44, as in the first embodiment.

  The operation of the data collection device 3 having such a configuration will be described below. When the threat control unit 42 reads the detection data of the pyroelectric sensor 30n at a predetermined cycle, the threat control unit 42 determines the presence of a pest based on the detection data. Here, when no pest is placed on the top plate 30k (upper surface of the main body housing), no temperature difference occurs between the detection data and the surrounding environment. However, when a pest is placed on the top plate 30k (upper surface of the main body housing), the body temperature of the pest is higher than the surrounding temperature. Change in temperature distribution). When the presence of a pest is detected on the upper surface of the main body housing 30a due to this temperature difference, the threat control unit 42 operates the lighting device 30m, for example, blinks only for a predetermined period, and performs threat control on the pest.

  As described above, according to the present embodiment, the pest detection unit 43 includes the pyroelectric sensor 30n that detects the temperature distribution above the main body housing 30a while exhibiting the same operations and effects as the first embodiment. The threat control unit 42 determines the presence of a pest based on a change in temperature distribution detected by the pyroelectric sensor 30n. According to this configuration, the presence or absence of a pest can be detected by a change in the temperature distribution, so that the pest can be detected with a simple configuration.

  In addition, according to the present embodiment, since the pyroelectric sensor 30n is used, it is only possible to detect the presence of a pest when the pest is actually placed on the upper part of the housing (top plate 30k). For example, the presence of a bird or the like about to fly over the main unit 30 can be detected in advance. Therefore, more effective control of harmful pests can be performed.

  Further, according to the present embodiment, the pyroelectric sensor 30n is used as the harmful animal detection unit 43, but the present invention is not limited to this, and a distance sensor may be used. As the distance sensor, various sensors having a ranging ability such as a laser radar or a millimeter wave radar can be used. In other words, the pest detection unit 43 may be configured by a distance sensor that detects the distance distribution of the space above the main body housing 30a. In this case, the threat control unit 42 can determine the presence of a pest based on a change in the distance distribution detected by the distance sensor. Even with such a configuration, the same operations and effects as those of the above-described embodiment can be obtained.

(Third embodiment)
FIG. 7 is a perspective view schematically showing the main unit 30 in the data collection device 3 according to the third embodiment. The data collection device 3 according to the third embodiment is different from that of the first embodiment in that a camera unit 30q is used as a pest detection unit 43 instead of the load detection sensor 30j. The basic system configuration is the same as that of the first embodiment, and the detailed description is omitted by citing the reference numerals.

  As shown in the figure, a support column 30p is fixedly installed in the vicinity of the main unit 30, and a camera unit 30q is installed above the support column 30p. The specific configuration of the camera unit 30q is the same as that of the camera unit 50 shown in the first embodiment, and a detailed description thereof will be omitted. The camera unit 30q captures a scene including the upper surface of the main body housing 30a of the main body unit 30 by a camera (not shown) housed in the housing. Image data captured by the camera unit 30q is output to the threat control unit 42 shown in FIG. In other words, in this embodiment, the camera unit 30q functions as a pest detection unit 43 (see FIG. 3) that detects the presence of a pest on the upper surface of the main body housing. Although omitted in FIG. 7, an illumination device 30 m that functions as a threatening unit 44 is provided on the upper portion of the main unit 30 as in the first embodiment.

  The operation of the data collection device 3 having such a configuration will be described below. When the threat control unit 42 reads image data captured by the camera unit 30q at a predetermined cycle, the threat control unit 42 determines the presence of a harmful animal by image recognition based on the image data. As a method for determining a pest by image recognition, for example, image data (comparison image data) read one cycle before is compared with the currently read image data, or captured without a pest. It is conceivable to make a determination based on a change in luminance by comparing image data (comparison image data) with currently read image data. That is, when a pest exists on the top plate 30k (upper surface of the main body housing), no special luminance change appears between the read image data and the comparison image data. However, when a pest exists on the top plate 30k (upper surface of the main body housing), a luminance change corresponding to the pest appears in the read image data. When the presence of a pest is detected on the upper surface of the main body housing 30a due to the change in brightness, the threat control unit 42 controls the lighting device 30m to blink, for example, for a predetermined period of time, thereby performing threat control on the pest.

  As described above, according to the present embodiment, the same effects and advantages as those of the first embodiment are achieved, and the pest detection unit 43 captures a scene including the upper surface of the main body housing 30a of the main body unit 30 to obtain image data. The threat control unit 42 determines the presence of a pest by image recognition based on image data output from the camera unit 30q. According to such a configuration, a pest can be detected with a simple configuration that can be detected by image recognition.

  In this embodiment, the pest detection camera unit 30q is separately used. However, the data collection camera unit 50 may be used as necessary.

(Fourth embodiment)
FIG. 8 is a cross-sectional view schematically showing the data collection device 3 according to the fourth embodiment. The data collection device 3 according to the fourth embodiment is different from that of the first embodiment in the configuration of the threatening unit 44. The basic system configuration is the same as that of the first embodiment, and the detailed description is omitted by citing the reference numerals.

  As shown in the figure, a load detection sensor 30j functioning as a pest detection unit 43 is provided at the upper center of the main body housing 30a of the main body unit 30. A top plate 30k is disposed on the detection surface of the load detection sensor 30j. The top plate 30k has a substantially U-shaped cross section, and is attached so that the opening portion faces downward so as to cover the upper part of the main body housing 30a. The detection signal from the load detection sensor 30j is output to the threat control unit 42 shown in FIG. In other words, in the present embodiment, the load detection sensor 30j functions as the harmful animal detection unit 43 shown in FIG.

  The top plate 30k is made of a member (for example, metal) having excellent conductivity, and a pair (positive and negative) electrodes 30r are attached to the top plate 30k. The energization state and voltage for the pair of electrodes 30r are controlled by the threat control unit 42 shown in FIG. In other words, in the present embodiment, the pair of electrodes 30r functions as a threatening part 44 (see FIG. 3) that threatens the harmful animal. In the present embodiment, an antenna 30h that functions as the wireless communication unit 37 is installed on the top plate 30k.

First, the threat control unit 42 stores the total amount (reference load) of the top plate 30k, the antenna 30h, and the pair of electrodes 30r. When the threat control unit 42 reads the detection value of the load detection sensor 30j at a predetermined cycle, the threat control unit 42 compares the detection value with a reference load. Here, when no pest is placed on the top plate 30k (top surface of the main body housing), the detection value read from the load detection sensor 30j corresponds to the reference load, but the pest on the top plate 30k (top surface of the main body housing). Is loaded, the load increases by the weight of the pest, so the detection value read from the load detection sensor 30j does not correspond to the reference load. By this comparison, when the presence of a pest is detected on the upper surface of the main body housing 30a, the threat control unit 42 energizes the pair of electrodes 30r, for example, allows a weak current to flow through the top plate 30k for a predetermined period of time. Intimidate control against.
