The harmful bird repelling system of this embodiment includes a small capacity inverter for repelling harmful birds in addition to the inverter for photovoltaic power generation. By switching the inverter for repelling harmful birds at a random frequency, the frequency is changed after a certain period of time. As for the change of the frequency, the user can input the frequency for the time and the frequency into the inverter system, and can change the pattern at any time. If the frequency pattern is constant, the harmful bird learns the pattern, which may reduce the repelling effect of the harmful bird.

  The wiring breaker 56 is arranged in parallel with the wiring breaker 53. The wiring breaker 56 electrically connects and disconnects an external power system and the inverter 57. The wiring breaker 56 is electrically connected to the inverter 57 via the AC circuit 58.

  The inverter 57 is an inverter for killing harmful birds and has a smaller electrical capacity than the inverter 52. The inverter 57 generates switching noise at a random frequency by AC power. The switching noise is supplied to the noise radiating unit 3 through the AC circuit 58 and the DC circuit 59. The circuit breaker 56 and the inverter 57 may adopt a known circuit breaker and a power conversion device that are applied to the photovoltaic power generation technology as in the first embodiment.

Since the frequency of the switching noise emitted from the inverter 57 is different from the frequency of the switching noise emitted from the inverter 52 and is random, the frequency pattern is not learned by the pests. Therefore, it is possible to prevent the effect of repelling harmful birds due to familiarity with noise.

  According to the above pest repelling system 6, even if the pest is accustomed to noise of a certain frequency by switching a small capacity inverter for pest repelling at a random frequency in addition to the inverter for photovoltaic power generation, the frequency is Because it changes, it always stimulates the pest's hearing, and the effect of repelling the pest lasts.

FIG. 3A is a schematic configuration diagram of a harmful bird repelling system according to an embodiment of the present invention.

  The harmful bird repelling system of the present embodiment maintains the effect of repelling harmful birds by changing the strength of switching noise emitted from the inverter.

  The pest repelling system 7 includes a solar power generation system 2 c and a noise radiation unit 3. The solar power generation system 2c includes a solar cell 4 and a power conditioner system 5c.

  The power conditioner system 5c has a configuration in which a wiring breaker 56, an inverter 60, and a noise switching system 8 are added to the components of the power conditioner system 5a of the first embodiment. The wiring breaker 56 is arranged in parallel with the wiring breaker 53. The wiring breaker 56 electrically connects and disconnects an external power system and the inverter 60. The wiring breaker 56 is electrically connected to the inverter 60 via the AC circuit 58. The inverter 60 is an inverter for killing harmful birds and has the same capacity as the inverter 52. In the power conditioner system 5c, operation switching and operation time of the inverter 52 and the inverter 60 can be arbitrarily set. In this way, the switching of the switch terminals A, B, and C can be changed over a certain period of time, and the extermination effect can be maintained. This is because the pattern may be recognized by the pests with only a certain pattern, and the effect may be reduced.

  The noise switching system 8 includes a changeover switch 81 and noise filters 82a and 82b. The changeover switch 81 is connected to the output line 31 that communicates with the noise radiation unit 3. The changeover switch 81 has a plurality of contacts. As for the change in strength, the user inputs the time and level into the sunlight PCS, and the pattern can be changed at any time. The noise filters 82a and 82b are connected in series to an output line 83 to which the changeover switch 81 and the DC circuit 59 are connected. The changeover switch 81 illustrated in FIG. 3B has three contact points, and can arbitrarily switch three types of noise. That is, the changeover switch 81 includes switch terminals A, B, C, and D. An output line 83 is connected to the switch terminal A. An output line 84 is connected to the switch terminal B. The output line 84 is connected to an output line 83 that connects the noise filter 82a and the noise filter 82b. An output line 85 is connected to the switch terminal C. The output line 85 is connected to an output line 83 that connects the noise filter 82 b and the DC circuit 59. Further, if the noise switching system 8 is provided with a timer that can arbitrarily set the switching time of the switch, the intensity of the switching noise can be changed every arbitrary fixed time. Note that the changeover switch described above is not limited to three types of noise, and four or more types of noise may be selected.

  An example of the operation of the harmful bird repelling system of this embodiment will be described with reference to FIG.

  The DC power supplied from the solar cell 4 is supplied to the inverter 52. The DC power is converted into AC power by an inverter 52. When the switch 81 makes the switch terminal A and the switch terminal D conductive, the switching noise released from the inverter 52 or 60 is output from the DC circuit 59 via the noise filters 82b and 82a during the operation of the inverter 52 or 60. The noise radiation unit 3 is supplied through the line 31. Next, when the changeover switch 81 is operated so that the switch terminal B and the switch terminal D are conducted, the switching noise is transmitted to the noise radiation unit 3 through the output line 84 and the output line 31 via the noise filter 82b. . Next, when the changeover switch 81 is operated so that the switch terminal C and the switch terminal D become conductive, the switching noise is transmitted to the noise radiation unit 3 through the output line 85 and the output line 31. As described above, when the switch 81 selects the continuity between the switch terminal A and the switch terminal D, the switching noise is emitted weakest. On the other hand, when the continuity between the switch terminal C and the switch terminal D is selected, the switching noise. Can be released most strongly. Since the intensity of the switching noise emitted as described above changes, the auditory stimulus given to the harmful bird changes, so it is possible to prevent the effect of repelling the harmful bird due to the familiarity of the noise. Moreover, the panel of the solar cell 4 is not soiled by the pests of the pests by removing the pests. Therefore, a decrease in power generation efficiency of the solar cell 4 can be prevented.

  According to the pest repelling system 7 described above, the output noise to the noise radiating unit 3 for pest repelling can be adjusted in several stages. Therefore, even if the pest bird gets used to a certain level of noise, the noise intensity changes. As a result, the hearing of the harmful birds is always stimulated, and the effect of repelling the harmful birds is sustained.

The noise radiating unit 3 radiates the switching noise into the atmosphere. This emitted switching noise drives away the harmful birds. Then, when the preset time is reached, the operation of the inverter 57 is switched.

  In the operation time zone of the inverter 57, the inverter 57 converts AC power supplied from the power system into DC power. The DC power is supplied to a DC load (not shown). During the operation of the inverter 57, the switching noise released from the inverter 57 is supplied to the noise radiation unit 3 through the output line 31 via the AC circuit 58 and the DC circuit 59. The noise radiation unit 3 radiates switching noise emitted from the inverter 57 into the atmosphere. Pests are exterminated by the radiated switching noise. Since the frequency of the switching noise emitted from the inverter 57 is different from the frequency of the switching noise emitted from the inverter 52 and is random, the frequency pattern is not recognized by the pests. Therefore, it is possible to prevent the effect of repelling harmful birds due to familiarity with noise.

  3B, when the changeover switch 81 of the noise changeover system 8 makes the switch terminal A and the switch terminal D conductive, the inverter 52 or 60 is discharged from the inverter 52 or 60 during operation. The switching noise transmitted from the DC circuit 59 is transmitted to the noise radiation section 3 through the output line 31 via the noise filters 82b and 82a. Next, when the changeover switch 81 is operated so that the switch terminal B and the switch terminal D are conducted, the switching noise is transmitted to the noise radiation unit 3 through the output line 84 and the output line 31 via the noise filter 82b. . Next, when the changeover switch 81 is operated so that the switch terminal C and the switch terminal D become conductive, the switching noise is transmitted to the noise radiation unit 3 through the output line 85 and the output line 31. In this way, when the switch 81 selects the conduction between the switch terminal A and the switch terminal D, the noise is emitted most weakly, while when the conduction between the switch terminal C and the switch terminal D is selected, the noise is emitted most strongly. Can be made.

  According to the pest repelling system 9 described above, since the switching frequency and the strength of the switching noise change, the hearing of the pest is always stimulated and the pest repelling effect is sustained. Moreover, since the panel of the solar cell 4 is not polluted by the pest of the harmful bird by removing the harmful bird, the power generation efficiency of the solar cell 4 is prevented from being lowered.
