Description

Bird and Pest Control {Bird / Pest repeller}

The present invention relates to the fight against algae and pests, and more specifically, to combat algae or pests by using ultrasonic waves, by automatically changing the frequency of the ultrasonic wave to be used, the target birds or pests to be eliminated ultrasonic and sound waves It relates to the fight against algae and pests that can increase the effectiveness of the prevention by preventing immunity.

As humans have gone through tens of thousands of years of civilization, they have been trying to eliminate the dangers of the development of civilization and preserve humanity from the threats of survival.

The origin of the rapid development of human civilization came from the beginning of agriculture, and through cultivation, mankind achieved stable food supply, and it was possible to pursue a planned and stable life away from the irregular and unplanned way of life. Development has begun to accelerate.

By the way, there were several harmful animals that hinder agriculture that provides a stable life as above, and the cultivator protects the crop from many enemies, from the growing season of the crop to the pests that afflict and to the algae that peck when it matures. Has been trying to achieve a stable harvest.

By the way, algae are beneficial to humans by eating harmful insects in normal times, but in the harvest season, the algae are harmful to the cultivators, and mankind has used various methods to protect the crops from these algae. By simply hanging a sparkling line around the farmland, the bird's eyes are deceived and inaccessible, and by setting up scarecrows, which are often found on farmland, in the fall, they look like humans in the eyes of birds. Preventing access to cropland.

By the way, such a method of combating the visual effect is effective for a while after installation, but a few days after the birds can be noticed that the method is very less effective, to compensate for this shortcomings, using a method that gives an auditory stimulus, intermittently It was a method of firing an air gun or chasing a person with a gong.

However, this is also effective only when a gunshot is struck or when a gong is beaten or braised, and after a while the birds come back and peck on crops such as grains and fruits, which consumes a lot of manpower and makes it impossible to eradicate them completely. There is a problem.

In addition, algae can interfere with the operation of the aircraft, and the algae that live near the runway are sucked into the propeller during takeoff and landing of the aircraft, causing the engine to break down, causing large accidents. A device for shooting a gun or automatically firing a dread bullet was installed around the runway, but it did not show a similar effect.

On the other hand, algae are harmful to humankind not only in rural areas but also in cities, such as the magpie nesting in Jeonju.

In general, magpies nest and lay eggs on tall trees between March and June, during the spawning season. In the city, the magpies are considered more durable and stronger than the trees, so the magpies are placed between the distribution line and the finish line on the Jeonju. There are many cases where nests are gathered by collecting branches, which causes short circuits of power distribution lines, causing frequent power outages.

Therefore, KEPCO and electric companies put a lot of manpower and money in order to remove the magpies that cause the above problems.Because of the physiological characteristics, magpies will be built in a few days after the house is removed. It is not worthwhile to invest a lot of manpower.

Various devices and methods have been devised for automatically eradicating the bird's harmful activity to humans. The classification of such devices includes a bird's sight device, a bird's tactile device, and a bird's sense of smell. It may be classified into a used device, a device using a bird's hearing, and a device for changing the structure of a power distribution facility.

Apparatus using a bird's eye view is to use a reflector (mirror) (Utility Publication No. 1998-59649, Published Patent No. 1998-19436), such a device is effective the first few times, but the learning ability of the bird There is a problem that the effect is quickly lost.

In addition, the device using the tactile sensation of the bird has a method of stimulating the tactile sensation of the bird by installing a sharp sticky place where the bird can sit, but this also has a problem that the effect of the sticky falls off soon to exert the effect.

In addition, as a device using the smell of algae, there is a device for injecting chemicals such as solvent, tear gas, capsaicin (Utility Model Registration No. 203307), but these chemicals are less effective when prolonged, In addition, this chemical smell is harmful to humans as well as algae, there is a problem that pollutes the environment.

In addition, as a device for changing the structure of the power distribution equipment, there is a device that inserts a diaphragm between the insulators of Jeonju so that the nest does not touch the distribution line even if the magpie nests in Jeonju (Private Publication No. 1997-19919). These devices also have a problem that the effect is reduced by creating a nest away from the installed place according to the learning ability of the magpie over time.

On the other hand, the device using the bird's hearing includes a device that installs the bird in a nesting position to generate a loud sound when the approach of the bird is detected (utility model registration No. 171141), but the device is not only a bird There is a problem that causes noise pollution because the audible sound that is loudly heard even in the human ear.

On the other hand, if the bird damages the surrounding environment of humans, there are many harmful animals and pests that directly harm living in human living space, for example, rats and cockroaches.

In the case of the rats and cockroaches, such as eating food or moving pathogens, the pests or poisons are installed everywhere and the pests or pests are eaten by killing them by eating them.

However, such a method has a serious effect on humans as well as harmful animals or pests, and requires much attention in handling and using them, and also prevents the killing of pests and animal carcasses from being exposed to children or pets. There is a problem that is cumbersome to pay attention to.

In order to solve the various problems as described above, the use of ultrasonic extermination, for example, Utility Model Registration Publication No. 1997-2390 (Ultrasonic Pest Control System), by oscillating ultrasonic waves that harmful animals or pests do not like The device was designed to increase the eradication rate and to avoid harm to humans.

Ultrasound refers to sound waves with a frequency higher than audible frequency (16 to 20,000 Hz). Among them, in order to combat birds, pests and pests, in general, ultrasonic signals in the frequency range of 50,000 Hz or less are used to combat them.

However, Utility Model Registration Publication No. 1997-2390 uses a method of converting a frequency using a variable resistance from time to time, in order to prevent immunity of harmful animals and pests by a single frequency of ultrasonic waves, the prior art as described above. There is a disadvantage that the user must adjust the variable resistance from time to time, and the change of the frequency manually adjusted by the user is also a disadvantage that the immune effect is not completely solved.

An object of the present invention is to solve the problems of the prior art as described above, in the fight against algae, harmful animals and pests by using ultrasonic waves, without the need for manual operation of humans, the ultrasonic frequency, etc. The modification is to provide a bird and pest control that can effectively combat birds, pests and pests without being immune to the ultrasound.

Operation of the embodiment of the present invention made as described above is as follows.

The user controls the operation of the retirement by operating the respective switches SW21, SW22, SW23, and SW24 of the operation selector 20.

First, the operation of the entire circuit is started by turning on the first switch SW21, and the operation mode is selected by operating the second switch SW22, as shown in Table 1 below. Four modes are set: first mode, second mode, third mode, and test mode.

16 ultrasonic waveforms Occurrence time Repeat count First mode 3 to 5 random selections 1 to 4 minutes 1 to 10 random 2nd mode Full random selection 15 seconds to 1 minute 1 to 3 random 3rd mode 4 to 6 random selections 30 seconds to 2 minutes 1 to 5 random Test mode Sequential selection 15 seconds 3rd time

By operating the third switch SW23, it is possible to select whether to operate only during the day or at night, and when operating only during the day, the operation of the circuit is determined according to the operation of the day / day discriminating unit 10. .

That is, during the day, the photoelectric switch 11 operates according to the sunlight to operate the circuit, and the light emitting diode is lighted on the display unit 80 to inform the user of the operation, and the photoelectric switch 11 at night. Does not operate so that the circuit does not operate, and the corresponding light emitting diode does not light up on the display unit 80 so that the user can know the fact.

In addition, by operating the fourth switch SW24, the volume of the ultrasonic waves output from the speakers SP1, SP2, SP3, SP4 of the ultrasonic output unit 70 is appropriately adjusted according to the size of the use space.

As described above, when the setting selected by the user is output from the operation selector 20, the controller 40 starts a control operation according to the input signal.

First, judging whether to use both day and night or only during the day according to the value of the third switch (SW23) (S10), when set to use only during the day and night discrimination unit 10 The input signal is read to determine whether the current day or night (S20).

In the case of the day, a signal indicating that it is in the daytime state is output from the day and night determination unit, and the control unit 40 reads the operation mode (S30), and in the case of the night, the standby state until the day is reached without entering the state of the operation mode reading. Becomes

On the other hand, when using both day and night in the day and night use selection determination step (S10), the process proceeds to the step (S30) for reading the operation mode irrespective of the signal of the day and night determination unit 10.

After reading the operation mode, the volume is read (S40).

When the operation mode set by the user is the first mode, as shown in Table 1, the controller 40 randomly selects three to five waveforms among the sixteen ultrasonic waveforms stored in the memory 52. In order to select, the generation time is set to about 1 minute to 4 minutes, and is controlled to be repeated at random for 1 to 10 times (S50).

Specifically, when the user sets the operation mode to the first mode, the controller 40 randomly selects three to five randomly among 16 ultrasonic waveforms stored in the memory 52. The first ultrasonic waveform is controlled to oscillate by setting a time within a time range of 1 minute to 4 minutes, and when the set time has elapsed (S60), the frequency is changed to the next ultrasonic waveform to control the oscillation. (S70).

By repeating the above situation, when all the oscillations for the selected waveform is finished, the operation is repeatedly oscillated for 1 to 10 times.

When the repetition is repeated as many times as set above, the process returns to the step of randomly selecting three or five of the ultrasonic waveforms stored in the memory 52, and repeats the above operation.

In the operation mode reading step (S30), even if the operation mode is the second mode and the third mode, the control unit 40 controls the oscillation by changing the oscillation frequency and the ultrasonic wave in the manner as shown in Table 1, thereby eliminating Prevents the subject from being immunized by repetition of the same signal.

The ultrasonic frequency according to the object to be removed is set as shown in Table 2 below, and the memory 52 stores the ultrasonic waveforms disliked by the object within the corresponding frequency standard in a digital form.

Eradication target Ultrasonic Frequency Specification Usage Birds 20KHz to 25KHz Agriculture, fishery, airport pest 20KHz to 40KHz Household, agricultural Rat, cat 20KHz ~ 50KHz Household, Warehouse moth 20KHz to 40KHz Agricultural, household Livestock 20KHz to 25KHz Agricultural, household

The memory device 52 may use a general EPROM, but may also use an EEPROM or other memory device, and the ultrasonic sounds stored therein are signals that the object to be eradicated. (E.g. nemesis, cognates, etc.), you can increase the number of ultrasonic sounds stored according to the capacity of the memory device and add them as new sounds are developed. have.

The ultrasonic oscillation control signal output from the controller 40 is divided into a frequency selection signal Sf and a sound selection signal Ss, and the sound selection signal Ss is a memory device in which an ultrasonic waveform which the object to be eliminated is stored ( 52) Designate address number in.

Then, the frequency selection signal Sf controls the counting time of the counter 51 so that the frequency of the signal output from the counter 51 changes so that the ultrasonic wave read and output from the storage device 52 is changed. The output time of the waveform changes.

Therefore, as shown in FIG. 3, the signal output from the storage device 52 is frequency modulated by the digital value of the corresponding ultrasonic waveform, thereby solving the shortcomings of the ultrasonic wave with a shorter transmission distance, thereby making the ultrasonic wave to a far distance. It can be used to deliver effective combat in large areas such as farms and airports.

The digital-analog converter 60 converts the digital value of the ultrasonic waveform output from the storage device 52 into an analog signal and outputs the analog signal, as shown in FIG. 4.

Meanwhile, the controller 40 outputs the volume control signal Sv according to the value read in the volume reading step S40, and the volume controller 71 adjusts the output amount of the amplifier according to the volume control signal Sv.

The amplifier 72 amplifies and outputs a signal output from the digital-to-analog converter 60 according to a value output from the volume controller 71, and the signal is low impedance through an impedance matching unit 73. Is converted into a high impedance value and transmitted to the speakers SP1, SP2, SP3, and SP4 of the speaker unit 74, and each speaker transmits the input signals by ultrasonic waves.

Each of the speakers SP1, SP2, SP3, SP4 of the speaker unit 74 uses a piezo ceramic type as an ultrasonic speaker that outputs a frequency of 5KHz to 50KHz, but uses a large output capacity. Cobalt speakers are used for airports, and speakers with other similar functions may be used.

On the other hand, the signal generator 50 is composed of a counter 51 and a memory device 52. When the performance of the controller 40 is good and the capacity of the memory device 52 is large, the signal generator 50 is directly controlled. The reading speed of the memory device 52 can be adjusted. In this case, the same effect can be obtained without the counter 51, and the form of the frequency selection signal Sf output from the controller 40 is directly It is replaced by a signal for controlling the clock speed of the memory device 52, in which the control unit 40 has a different shape of the frequency selection signal.

The power supply unit 30 for supplying the power of the circuit has a built-in electromagnetic shielding circuit, a built-in function to safely cut off lightning and overvoltage, and has a constant voltage compensation circuit, thereby ensuring stable operation in case of emergency.

In addition, the control unit 40 is additionally provided with a watchdog (watch-dog) function, it is automatically reset in the event of an error to prevent a malfunction.

Bird and pest repellent according to the present invention can be used by changing the frequency of birds such as magpies, crows, ducks, seagulls, pigeons and various pests such as mosquitoes, moths and harmful animals such as rats, squirrels, livestock, etc. It can also be used to prevent tampering.

Therefore, the present invention operating as described above, there is an effect that can prevent the access by birds and harmful animals and pests without causing environmental problems.

In addition, the present invention operating as described above, it is possible to prevent the target to be immunized as the signal to be used is simply repeated.

In addition, the present invention operating as described above has the effect that it can be used with a small amount of power even in a farm or airport of a wide area by transmitting a signal by frequency modulation to widen the reach of the ultrasonic signal.
