Description

  The present invention relates to an electric fence system that is installed to prevent invaders of harmful animals such as frogs, deer, and monkeys.

In recent years, damage to crops by pests such as spiders, deer and monkeys has become conspicuous.
Damage caused by pests has been increasing year by year, and the amount of damage has been as much as two hundred billion yen annually, and government subsidies have also been inflated to hundreds of billion yen.
In order to prevent this pest damage, it is currently used generally by an electric fence made of a bare wire to which a high voltage (pulse wave voltage) is applied, surrounding the cultivated area, It is an electric fence system that prevents invading pests.
Many electric fence systems have been proposed. For example, Patent Documents 1 and 2 can be cited.

JP2012-085612A JP 2012-135262 A

In such an electric fence system, there is a special problem when the harmful animal is a monkey.
Unlike monkeys and deers, monkeys have free limbs, so when they enter the fence, they sometimes climb up the pole of the electric fence.
In other words, in the column portion, for example, the column itself without a bare electric wire can be intruded without touching the bare electric wire by grasping with a hand and stepping on with a foot. Alternatively, it is possible to enter by simply touching one of the bare wires having a positive or negative potential.
In this case, the monkey is not energized, and no electric shock is generated. In other words, the repelling effect on the monkey cannot be obtained. Also, the educational effect of electric shock cannot be expected.

  The present invention has been made in view of the problems of such conventional electric fences. In addition to normal pests, the present invention is particularly designed to prevent monkeys from entering through the pillars of the electric fence. It is intended to provide a fence system.

The present invention of claim 1 is an electric fence system in which an electric fence to which a high voltage is applied is stretched to prevent invading pests.
The bare wire having both positive and negative potentials is wired in a plurality of stages with a conductive hook insulator formed by bending a metal wire with respect to the support pole of the electric fence, and the support portion between the bare wires having both potentials. The positive potential extension portion energized with the positive potential bare wire and / or the negative potential extension portion energized with the negative potential bare wire is provided to extend from the conductive hook insulator. The electric fence system is characterized by that.

The present invention of claim 2 is an electric fence system for preventing an invasion of a pest by stretching an electric fence to which a high voltage is applied.
The bare wire having both positive and negative potentials is wired in a plurality of stages with a conductive hook insulator formed by bending a metal wire with respect to the support pole of the electric fence, and the support portion between the bare wires having both potentials. A conductive tape provided with a positive potential extending portion energized with the positive potential bare wire, or / and a negative potential extending portion energized with the negative potential bare wire, on a side surface of the column, Or it exists in the electric fence system characterized by providing as a conductive paint .

  According to the present invention, since the positive potential extending portion and the negative potential extending portion are provided in the post portion of the electric fence, when the harmful beast, especially a monkey climbs the post portion and tries to enter, this positive potential extension portion is provided. It will touch the installation part and the negative potential extension part.

  In other words, in the strut part, since the lath potential extending part and the negative potential extending part are extended on the side surface between the bare wires, when the monkey climbs the strut part, it is energized between hands, feet, etc. I get an electric shock. Thereby, the high repelling effect with respect to a monkey is acquired, and the educational effect is also acquired.

FIG. 1 shows an example of an electric fence system to which the present invention is applied.
In the figure, 10 is an agricultural land area for agricultural products, 20 is an electric fence stretched around the agricultural land area 10, and 30 is a bare electric wire (fence line) to which a high voltage is applied. The electric fence area is not limited to agricultural land. This includes various facilities that are expected to be damaged by pests, barns, shrines, temples, gardens, and tourist areas.

As an example, the bare electric wire 30 of the electric fence 20 is supported on a support pole (pole) 40 via a hook insulator 41 as a five-stage wiring. This is a wiring that assumes a monkey of a beast.
Here, as shown in FIG. 2, the height of the support | pillar 40 is 210 cm, for example, the space | interval between electric wires is 30 cm, and the space | interval between adjacent support | pillars is 3-4 m.
Basically, the number of wiring steps and the height of the support column 40 are not particularly limited. It can be changed according to the type of pests expected. This is because the height varies depending on the type of pest. Also, the wiring interval and the column interval can be changed according to the kind of the harmful animal.

Since it is necessary to go in and out of the farmland area 10 at the time of work etc., the gate grip 50 which can remove the bare electric wire 30 suitably is provided as an entrance / exit.
The structure of the gate grip 50 is not particularly limited. For example, the grip 51 is formed of an insulating material such as plastic, and one end of the grip 51 is provided with a conductive hook (a collar, not shown) connected to the bare wire 30. It is preferable to provide conductive hooks (buts, not shown) that can be attached to and detached from each other on the bare wire 30 side.
When entering the agricultural land area 10, the hooks 51 are separated from each other with the grip 51. In addition, the installation location of the gate grip 50 is not limited to one location.

Reference numeral 60 denotes a system main body (box) in which the main body of the electric fence system is housed, and is usually installed beside the farmland area 10. This body is also basically a monkey as a harmful animal.
As shown in FIG. 1, the high voltage line (lead wire) 61 from the positive potential terminal 61 a of the system main body 60 is connected to the upper, middle, and lower levels of the five levels of bare wires 30 of the electric fence 20. Three wires are connected. On the other hand, the ground wire (lead wire) 62 from the negative potential terminal 62a of the system body 60 is grounded to the ground, and two of the five stages of the bare electric wires 30 have a negative potential other than the positive potential. Connected.

From this system main body 60, a high-voltage pulse wave voltage (for example, 10,000 V) is applied to the bare electric wire 30 having a positive potential of the electric fence 20.
Therefore, for example, when the monkey 70 of the harmful animal tries to enter the farmland area 10 and touches the bare electric wire 30, electric shocks are caused in various forms. For example, if the monkey's hand touches the positive potential bare electric wire 30 while the foot or body touches the ground or touches the negative potential bare electric wire 30, the positive potential bare electric wire 30, the body of the monkey 70, the land Current flows in the order of (grounding) and the bare electric wire 30 having a negative potential, and an electric shock is generated.

This electric shock causes the monkey 70 to receive an electric shock (in the case of a person, the shoe is an insulator and no current is applied, and no electric shock is generated). Since the current value at this time is small, the monkey will not be electrocuted, but because of the high voltage, the impact on the monkey 70 is extremely large.
Due to this electric shock, the monkey 70 is effectively repelled. Once an electric shock is received, the next pest invasion is prevented to some extent by the educational effect. Moreover, if the monkey is a harmful beast that can be communicated with friends, a prevention effect can be expected for the monkeys of the fellow.

The above intrusion form is an intrusion from the portion of the bare wire 30 between the struts 40. However, in the case of monkeys, the limbs are more free and the intellectual level is higher than that of sharks and deers. In addition to the intrusion from the unstable wiring portion, it is assumed that the intrusion climbs up the column portion. In fact, it has been confirmed that it climbs and invades.
In this case, since the interval between the bare electric wires 30 is about 30 cm in the column part, if the monkey is climbing up with a hand, just holding the column part without the bare electric wire 30 and hooking the foot on the column part, You can climb without getting an electric shock. That is, a monkey can enter.

In the present invention, such a climbing intrusion can be effectively dealt with.
First, an insulating material is used as the support column 40. For example, resin-made hollow columns such as fiber reinforced plastic (FRP) can be used. In the case of a metal hollow strut, a surface with an insulating treatment is used. The support column 40 is not limited to a hollow body.
As the hook insulator 41 to be attached to the support column 40, for example, a metal wire processed body as shown in FIGS. 3 and 4 is used.

Since this hook insulator 41 is made of a metal wire, it is a conductive hook insulator that has conductivity, and extends downward with a length of less than 30 cm (this length can be changed at any time depending on the spacing between the bare wires 30). ), A positive or negative potential extending portion 41a is provided.
The conductive hook insulator 41 has a coil-shaped mounting portion 41b mounted on the support column 40 at the center, and the hook portions 41c and 41c such as a triangle extending outwardly from the left and right of the mounting portion 41b are operated. When the person holds it by hand and contracts it a little, the inner diameter of the mounting portion 41b is increased. For this reason, it can be easily fitted into the column 40. If the hand is released after the fitting, the mounting portion 41b is reduced in diameter and mounted on the support column 40. The bare wire 30 is hooked, for example, by passing through the hook portion 41c.

There are various methods for hooking the bare wire 30.
For example, there is a method of hooking the end of the bare wire 30 sequentially through the hook portions 41c and 41c, but there is a case where the bare wire 30 is pulled out in advance and then hooked to the hook insulator 41 of the support column 40. It is necessary to put the bare wire 30 inside the hook portion 41c from the overlapping gap between the hook portions 41c bent into a triangle or the like.
At this time, if the plus or minus potential extending portion 41a extends long and the tip thereof is in close contact with the side surface of the support column 40, the gap is narrow and difficult to pass. A formation portion 411a may be provided.
In addition, the thing without the plus or minus electric potential extension part 41a of this invention is sold as an existing commercial item, and the insulator of this invention can be called the modified product (custom product).
That is, since a commercially available modified product is sufficient, it can be obtained at a relatively low cost.

The conductive hook insulator 41 is shared by both the positive potential metal wire 30 and the negative potential metal wire 30. When stopping the positive potential metal wire 30, the extending portion extending downward becomes a plus potential extending portion 41 a and hangs down along the side surface of the support column 40.
Further, when stopping the negative potential metal wire 30, the extending portion extending downward becomes the negative potential extending portion 41 a and hangs down along the side surface of the support column 40.

For this reason, when the monkey 70 of the harmful animal tries to climb the support column 40 when invading, grips the support column 40 with his hand and hooks his / her foot on the support column 40, the hand or foot is just the positive potential extending portion 41a. If the negative potential extending portion 41a is touched, an electric shock is generated.
At this time, since the plus or minus potential extending portion 41a extends downward and closes the column 40 portion between the bare wires 30 with almost no gap, when the monkey climbs the column 40 portion, the potential extending portion 41a Touching will cause an electric shock.
That is, when the monkey climbs, various cases are assumed in the column 40 part where the hand holds and where the foot is hooked, but the plus or minus potential extending portion 41a is connected to the column 40 part. Since the bare electric wires 30 and 30 extend almost without any gaps, it is possible to make an electric shock corresponding to almost all cases.

The plus or minus potential extending portion 41a is an extending portion extending downward, but conversely can be an extending portion extending upward. In this case, the uppermost conductive hook insulator 41 may have no potential extending portion.
Further, the conductive hook insulator 41 may be provided with both an extending portion extending downward and an extending portion extending upward from the left and right hook portions 41c, 41c. In this case, it is preferable to prepare two types of configurations in which the positions of the extending portions are shifted so that the plus and minus potential extending portions 41a do not interfere between the upper and lower insulators.
The conductive hook insulator 41 is made of a metal wire processed body. However, as long as it has a structure portion for stopping the bare wire 30 and has an extension portion 41a of plus and minus potentials, the present invention. Is not limited to this.

FIG. 5 shows another embodiment of the present invention.
In this embodiment, a commercially available conductive hook insulator 42 is used in place of the conductive hook insulator 41 having the positive or negative potential extending portion 41a. Alternatively, the negative potential extending portion 43 is used.
The conductive hook insulator 42 has hook portions 42c, 42c such as triangles on the left and right outer sides of the coil-shaped mounting portion 42b in the center portion. As described above, this is an existing commercial product. Therefore, it can be obtained at a low price.
Also, the plus or minus potential extending portion 43 of the accessory is simple in shape and can be provided as a bent body such as a metal wire, so that it can be provided at low cost.

Specifically, as an example, the front end side is bent into a hook shape or the like to form a hook portion 43a, and the hook portion 43a is hooked on the base of the hook portion 41c of the conductive hook insulator 41 and the long extension portion thereof. May be used by hanging along the column 40.
Of course, by this hooking, a predetermined voltage is applied from the bare wire 30 to the entire length of the plus or minus potential extending portion 43 made of a conductive member such as a metal wire.
As a result, the monkey gets an electric shock if he tries to climb the column 40.
Since the plus or minus potential extending portion 43 has a simple shape and only needs to be hooked on the hook portion 43a, the work itself is simple and good workability can be obtained.
At this time, if the tip of the lower end is unstable, it may be fixed with an adhesive tape or the like.

FIG. 6 shows another embodiment of the present invention.
In this embodiment, a commercially available conductive hook insulator 42 is used, while a positive or negative potential extending portion 44 is provided on the side surface of the support column 40, a conductive tape, a conductive paint, a thin metal plate, a bare wire. (Especially a thin flat electric wire) or the like.
Of course, since this conductive hook insulator 42 is a commercial product, it can be obtained at a low cost.

In this case, if the conductive hook insulator 42 is attached to the support column 40, the separate positive or negative potential extending portion 44 is sandwiched on the inside, so that they are electrically connected and become energized.
That is, a predetermined voltage is applied through the bare wire 30 and the conductive hook insulator 42 over the entire length of the plus or minus potential extending portion 44.
As a result, Isogo is a commercially available product. Further, since the plus or minus potential extending portion 44 is a separate body from the insulator itself, its length, width, shape, etc. can be freely set.
Further, if it is provided at the factory stage, for example, when the support column 40 is processed, it can be formed accurately and at a relatively low cost. Of course, on-site formation is also possible.

7 (A) and 7 (B) show another embodiment of the present invention.
In the embodiment of FIG. 7A, a plurality of plus or minus potential extending portions 44 are provided in the support column 40 as the same configuration as in FIG. Of course, the length, width, shape and the like can be freely set.
When the plurality of potential extending portions 44 are all set to the same potential, the energization opportunity for the monkey can be further increased. Further, in the plurality of potential extending portions 44, for example, if a positive potential and a negative potential are alternately combined, an electric shock can be generated just by holding the monkey with a hand. That is, high electric shock can be obtained.

In the embodiment of FIG. 7B, the plus or minus potential extending portion 44 is provided in a spiral shape on the support column 40 portion as the same configuration as in FIG. Of course, the length, width, shape and the like can be freely set.
Also in this case, if all the spiral potential extending portions 44 are set to the same potential, the energization opportunity for the monkey can be further increased. Further, as the plurality of spiral potential extending portions 44, for example, if a positive potential and a negative potential are alternately combined, an electric shock can be generated only by the monkey holding the hand. That is, high electric shock can be obtained.

Such intrusion prevention of harmful monkeys and the like is performed by the system main body 60 described above.
FIG. 8 is a schematic block diagram showing an outline of the system main body 60.
Reference numeral 100 denotes a control unit with a built-in CPU in which device systems such as electric parts and electronic elements necessary for driving the system are incorporated. Programs and data necessary for this control are stored in the memory unit 110.

The system main body 60 can correspond to a plurality of power supplies. That is, a plurality of power sources 1 to 3 can be connected to the control unit 100 through the power source switching unit (means) 120.
For example, the power source 1 is a dry battery, the power source 2 is a car battery, and the power source 3 is a solar cell made of a solar panel. The power supply is not limited to this, and power can also be supplied to the installation location of the system main body 60 through an AC power connection line (extension cord, utility pole wiring, etc.). A small generator can also be used.

The power supply voltage is usually about 12 V, and the power supply type may be selected according to the total extension distance of the bare wire 30. For example, when the total extension distance is about 3 km, a dry battery or a solar battery can be used. When the total extension distance is as long as about 6 to 9 km, it is preferable to use an automobile battery.
In the case of the present system main body 60, for example, in the case of using eight single alkaline batteries, when used for 12 hours a day, it can correspond to about 50 days. The power supply voltage is not limited to 12V, and may be 6V or 24V, for example.

Power consumption is important in this system. For this reason, an operation changeover switch 130 that can select an operation state (for example, continuous (all day), night, daytime, disconnection, etc.) is attached to the front surface of the system main body 60 and linked to the control unit 100.
In addition, an output lamp 140 that is lit (flashing is also possible) during operation and a light receiving sensor 150 that detects outdoor luminance (brightness) are provided on the front surface of the system main body 60, and these are also connected to the control unit 100. I'm allowed.

The operation changeover switch 130 (rotary type) is selectively used according to the advancing situation of the harmful animals.
For example, when the contact of the monkey 70 goes all day, the switch 130 is set to a continuous scale. If the contact is at night, switch 130 is set to the night scale. If the contact is daytime, switch 130 is set to the daytime scale. The switch 130 is set to the cutting scale in the case of seasonal operation unnecessary time or emergency. By these operations, power consumption can be saved.

In addition, when the operation changeover switch 130 is operated at night or during daytime operation, for example, the operation may be switched manually at a predetermined time.
In this system, since the light receiving sensor 150 is provided, it can be automatically switched by the function of this sensor. For example, during nighttime operation, when light reception by the light receiving sensor 150 exceeds a predetermined luminance value in the morning, the switch is turned off, and when it becomes lower than the predetermined luminance value in the evening, the switch is turned on. During daytime operation, conversely, in the evening, the switch is turned off when the luminance value is below a predetermined luminance value, and when the predetermined luminance value is exceeded in the morning, the switch is turned on.
These driving operations are performed by the light receiving sensor program (light receiving sensor driving means) stored in the memory unit 110 and the control unit 100.
By this drive, it is not necessary to go to the installation site, and the trouble of operating the switch can be saved. In addition, the effect of preventing forgetting to operate the switch can be obtained.

  Reference numeral 200 denotes a pest detection sensor unit, which is linked to the control unit 100 of the system main body 60. This driving is performed by a control program for the pest detection sensor unit (pest detection sensor unit driving means) stored in the memory unit 110 and the control unit 100.

  The pest detection sensor unit 200 displays at least pest contact detection means 210 that detects contact of the pest with the electric fence 20, contact count means 220 that counts (counts) this detection, and contact count data. Data display means 230. Preferably, a contact date / time recording means 240 for recording the contact date / time at the time of contact with a pest is provided. The contact date and time of this means is usually displayed on the data display means 230 together with the number of times of contact (count number).

When the pest monkey 70 contacts the electric fence 20, the pest contact detection means 210, as described above, in the order of the bare wire 30, the body of the monkey 70, the land (ground), or the positive potential bare wire 30, Since current flows in the order of the body of the monkey 70 and the bare electric wire 30 having a negative potential, the electric current is detected and a change in voltage is detected.
The contact counting means 220 that counts this detection may be anything that stores the number of detections. For example, it is composed of counter parts. It can also be provided in the memory unit 110 on the control unit 100 side as a software count storage unit.

The data display means 230 for displaying data is not particularly limited as long as it has a display function. An example is a liquid crystal display. As long as the number of contact with the monkey, only a 7-segment type numeric display such as an LED can be used.
The contact date and time recording means 240 is a means for recording including the date and time when the monkey 70 is in contact, specifically the time. Specifically, for example, referring to the date and time of the calendar function means and the clock means incorporated in the control unit 100, the corresponding date and time of the pest contact is recorded.
This recording means may correspond to a single storage element, but can also be provided in the memory unit 110 on the control unit 100 side as a software date / time storage unit.

An example of the data display means 230 is as shown in FIGS. 9A and 9B.
FIG. 9A shows a one-line display type liquid crystal display 230a.
The first number “3” is the number of contacts, and 231 is the title name. The subsequent display is the first contact date and time 232 is the title name. Since the number of times of contact is not limited to one, the second and subsequent displays are switched by, for example, operating a switch button (switch) 233 provided in the vicinity. Reference numeral 234 denotes a reset switch for resetting the display.
In this case, since the display device may be small, the cost can be reduced.

FIG. 9B illustrates a multi-line display type liquid crystal display 230b.
The upper number “3” is the number of contacts, and 231 is the title name. The lower display shows the date and time of contact multiple times, and 232 shows the title name. In this case, it is convenient if the number of times of contact is large. For example, when the number of touches displayed is 10 rows, when the number of contacts is exceeded, switching is performed by operating a switch button (switch) 233 provided in the vicinity. Reference numeral 234 denotes a reset switch for resetting the display.
In this case, the display is large and the cost is increased, but the visibility is improved. Of course, the number of switching operations can be greatly reduced.

  When there is such a pest detection sensor unit 200, when the monkey 70 touches the electric fence 20, or when it tries to climb the column 40 part, the contact is detected by the pest contact detection means 210, Immediately it is counted by the contact counting means 220. If the contact date and time recording means 240 is present, the contact date and time is also stored and displayed on the liquid crystal displays 230a and 230b together with the number of times of contact.

Thus, even if the monkey 70 does not enter the cultivated land area 10, it can be known by simply touching the electric fence 20.
Moreover, when there is the pest detection sensor unit 200, the number of times of contact and the date and time of contact can be understood, so the activity status of the monkey 70 throughout the day (daytime) can be understood. You can see if it is centered at night or early in the morning or at dusk. In addition, you can understand the seasonal activities.
As a result, the power can be turned off during an unnecessary time zone or season. That is, it is possible to manage a fine electric fence system. As a result, cost reduction is achieved.

Not only the monkey 70 but also the electric fence 20 sometimes touches the electric fence 20 due to the growth of plants or the shaking of plants. At this time as well, as in the case of the monkey 70, energization occurs, causing a change in current and a change in voltage. However, in the case of vegetation, since the resistance value is larger than that of the monkey body, the change value is small.
Therefore, it is preferable to provide the malfunction prevention means 250 by paying attention to this characteristic. In other words, it is a means that does not operate at the extent of contact with plants.

As this means, change value storage means for temporarily storing change values of current and voltage when monkey 70 or vegetation is in contact, and assumed change values (assumed reference values) when pest contact is stored. It is preferable that the reference value storage means and the comparison judgment means for comparing and judging these are configured.
In the pest contact detection means 210, whether or not the detected current or voltage change value has reached the assumed reference value is determined by the comparison determination means, and only when the estimated reference value has been reached. What is necessary is just to drive the count means 220 grade | etc.,.
As a result, malfunction due to contact with the vegetation is prevented. That is, high reliability of the pest detection sensor unit 200 is ensured.

When the pest detection sensor unit 200 is provided, various management modes of the electric fence system can be realized in cooperation with various recent communication means.
For example, the pest detection sensor unit 200 is provided with a transmission unit 260 and a reception unit 270, and necessary communication programs and application software are stored in the memory unit 110 of the control unit 100.
And various cooperation operation | movement can be made to cooperate with the external apparatus with which the same kind of communication program and application software incorporated in cooperation with these communication programs and application software.
Examples of the external device include a camera 300, a controller (electronic device) 400 such as a personal computer device, and a mobile phone 500. Further, the data display means 230 can be linked as a portable liquid crystal display.

First, cooperation with the camera 300 will be described.
The camera 300 is driven by a signal from the transmission unit 260 of the pest detection sensor unit 200 and is installed at a position for imaging all or a part of the electric fence area.
When the monkey 70 comes into contact with the electric fence 20, the detection signal of the pest contact detection means 200 is transmitted to the camera 300 by the transmission unit 260 to drive the camera 300 (with the shutter turned on), and in the electric fence area. Image all or part of it.

  The cooperation between the camera 300 and the pest detection sensor unit 200 may be wireless or wired. The image of the camera 300 may be a still image or a moving image. Further, the installation location of the camera 300 is not limited to one location, and may be a plurality of locations.

The captured image of the camera 300 is temporarily stored in a built-in attached memory (SD, SDHC, SDXC card memory, etc.). The simplest confirmation of an image can be performed by displaying it on a display (liquid crystal panel) of the camera itself.
As a result, a large amount of information such as the type of pests, the number of heads, the parent-child relationship, the presence / absence of a herd and the contact location can be obtained. In addition, the terrain of the cultivated land area 10 (less vegetation, few hidden places, etc.) and external roads (close to roads where people and cars pass), surrounding facilities (close to facilities where people come and go) It is also possible to elucidate the correlation with the advancing situation of the pest 70.
In other words, it is possible to manage a rational electric fence system based on the data.
For example, if an unnecessary electric fence part is understood, the electric fence itself can be reduced. Thus, cost reduction can be obtained. Furthermore, it is possible to make a judgment that the facility for the electric fence to this part is unnecessary in the first place.

The captured image of the camera 300 can be taken out of the attached memory from the camera 300 and imported into a controller 400 such as an external device such as a personal computer device. This may be done using a commercially available card reader.
In the case of the controller 400, since a memory device such as a large-capacity HD can be built-in (or externally attached), a large amount of data can be stored for a long period of time.
The controller 400 can also transfer and store the contact count of the contact count means 220 and the contact date and time of the contact date and time recording means 240 through the transmitter 260 of the pest contact detection means 200.

  The captured image of the camera 300 can be stored on the control unit 100 side through the reception unit 270 of the pest detection sensor unit 200 by a communication program and application software built in the camera. For example, an external memory 160 such as an HD may be provided on the control unit 100 side and transferred to this. The external memory 160 can be removed and connected to the controller 400 for use. Further, the internal data can be transferred to the controller 400 side through the transmission unit 260 of the pest detection sensor unit 200 without removing the external memory 160. These transfers can be performed wirelessly or wired.

Since it is troublesome to remove the memory attached to the camera 300 and the external memory 160, a corresponding communication program and application software can be incorporated and transferred to the controller 400 via the communication means 600 on the Internet.
In this case, it is not necessary to go to the site of the electric fence 20, and good workability can be obtained. Moreover, the appearance status of the pest 70 can be transferred to the controller 400 in real time.
When linked with the communication means 600 of the Internet, the number of contact of the pest 70 from the pest detection sensor unit 200, the contact date and time, and the captured image can be transmitted to the predetermined mobile phone 500 in real time. In the case of Internet connection, although the cost is high (because it is necessary to incorporate components and elements for connection to the Internet in the control unit 100 or the like), sufficient practicality can be obtained in large-scale farms, golf courses, and the like.
In the case of a golf course, if it is devastated by a pest 70 at night, if the fact cannot be detected quickly, a procedure such as temporary repair may be delayed, and the start in the early morning may not be in time. For this reason, a great advantage is obtained for transmission to the mobile phone 500.

From such a viewpoint, as shown in FIG. 10, the data display means 230 can be a portable liquid crystal display 230c.
In this case, it is of a multi-line display type, the number “3” on the upper surface of the display is the number of times of contact, and 231 is the title name. The lower display shows the date and time of contact multiple times, and 232 shows the title name. For example, when the number of touches displayed is 10 rows, when the number of contacts is exceeded, switching is performed by operating a switch button (switch) 233 provided in the vicinity. Reference numeral 234 denotes a reset switch for resetting the display. This switching may be performed by scrolling up and down the screen by incorporating scroll type application software.

Necessary communication programs and application software are incorporated in the main body of the data display means 230, and the system main body 60 is directly controlled wirelessly or by wire through the transmission unit 260 and the reception unit 270 of the pest detection sensor unit 200. Unit 100 can be linked.
Further, the display function of the portable liquid crystal display can be exhibited through the Internet in cooperation with the communication means 600 of the Internet.
In addition, by using such a function, the data display means 230 can be replaced with the mobile phone 500. Even when the portable liquid crystal display 230c and the mobile phone 500 are linked as the data display means 230, the liquid crystal displays 230a and 230b can be provided on the front surface of the system main body 60 separately from these.
