Beehives Monitoring System and Method for Bee Protection {BEEHIVE MONITORING SYSTEM FOR HONEY BEE PROTECTION AND METHOD THEREOF}

The present invention relates to a beehive monitoring system and method for bee protection, and more particularly, a beehive monitoring system and method for bee protection for accurately determining whether the wasp or wild bee invasion by detecting the sound generated inside the beehive It is about.

Bees play an important role in terrestrial ecosystems, including pollinating flowers and making honey. These honey bees are increasingly threatened by indiscriminate attacks by wasps and wild bees, and even the ecosystem is threatened.

In general, wasps often appear from mid-May to late autumn each year, attacking bees and, in severe cases, often destroying bees in a bucket within an hour or two. The behavior of wasps is very different from that of bees. Originally, wasps are carnivorous insects that catch bees and other small insects to feed their young.

Therefore, the wasp flies to the apiary to attack the bees. At first, one or two birds fly around the beehive, attack and kill the bees that pass through the beehive, and then feed on their chicks. Fly in a turn and turn into a group attack type.

This mass attack involves 20 to 30 long-lived wasps indiscriminately strangling about 5,000 to 25,000 bees for 30 minutes to 3 hours, roughly one wasp averaged 14 One kill every second.

In addition, when bee strikes weaken, they invade the hive and begin to bite the larvae, killing them for a short time. Therefore, beekeepers of beekeeping farmers actively relieve them by circulating the apiary to reduce the damage caused by wasps, and using wasps nets to kill wasps or find and remove nearby wasp houses.

However, these remedies are not only dangerous but also require a lot of manpower and expense.

In order to solve this problem, a structure was added to the hive to restrict access to the wasp, but the beekeeper has to check a plurality of beehives at a glance so that the work efficiency is low, and the bees near the hive are still in danger.

The background technology of the present invention is disclosed in Republic of Korea Patent Publication No. 10-1833247 (2018. 03. 02. notification).

The control unit may further determine that the amplitude value and the frequency from the microprocessor after a set time have elapsed when the amplitude value received in real time is greater than the preset amplitude average value and the frequency band received in real time is outside the preset frequency band. When the band is re-received and the re-received amplitude value is greater than the preset amplitude average value and the re-received frequency band is out of the preset frequency band, it may be determined that the wasp or wild bee has invaded.

The preset frequency band may be a frequency band corresponding to 100 to 500 Hz.

In addition, the manager terminal may be output by the administrator and the position of the beehive equipped with a warning alarm transmitted from the control server and the acoustic sensor corresponding to the corresponding location information.

Finally, the manager terminal 400 outputs the position of the beehive 100 provided with the warning alarm transmitted from the control server 300 and the acoustic sensor 110 corresponding to the corresponding location information.

FIG. 2 is a block diagram illustrating the microprocessor of FIG. 1.

As shown in FIG. 2, the microprocessor 200 according to the embodiment of the present invention includes an amplifier 210, an ADC 220, a Fourier transform unit 230, and a communication module 240.

First, the amplifier 210 is connected to each of the plurality of acoustic sensors 110 to amplify the sound signal detected from each of the acoustic sensors 110, respectively.

In this case, the amplifier 210 may be connected to the acoustic sensors 110 provided in each of the plurality of beehives 100 located in the area in a wired manner to quickly and accurately receive the sound signal detected from the acoustic sensors 110.

The ADC 220 converts the analog sound signal amplified from the amplifier 210 into a digital signal of '010110' type.

First, the receiver 310 receives an amplitude value, a frequency band, and position information of the corresponding acoustic sensor 110 from the communication module 240 in real time.

The controller 320 compares the amplitude value and the frequency band received by the receiver 310 with the preset amplitude average value and the preset frequency band, and determines whether the wasp 20 is invaded based on the comparison result.

At this time, the preset amplitude average value is set to an average value of amplitude values corresponding to the case where only bees 10 exist, and the preset frequency band is set to 100 to 500 Hz as a frequency band corresponding to the case where only bees 10 exist. do.

That is, since the frequency band for the sound made by the honeybee 10 is 100 to 500 Hz, and the frequency for the sound made by the wasp 20 is 700 to 1000 Hz, the preset frequency band corresponding to the case where only the bees 10 exist is 100. It is set to ~ 500Hz.

In detail, if the amplitude value received in real time from the receiver 310 is greater than the preset amplitude average value and the frequency band received in real time is out of the preset frequency band, the controller 320 may set the microprocessor after the set time has elapsed. The amplitude value and the frequency band transmitted from the communication module 240 of the 200 are re-received through the receiver 310, and the re-received amplitude value is larger than the preset amplitude average value and the re-received frequency band is the preset frequency band. In case of departure, the wasp 20 is determined to have invaded.

However, in the embodiment of the present invention, the bee 10 is not immediately strangled because the wasps 20 invade, but the wasps 20 may disappear by themselves while the administrator moves to the site. It is preferable to re-determine whether the wasp 20 is invaded after the set time has elapsed without transmitting an alarm.

In this case, the setting time may be set to 2 minutes, which may be set by an administrator.

Finally, the transmitter 330 transmits a warning alarm to the manager terminal 400 according to the determination result of the controller 320.
