[Action of electric fence device]
The operation of the electric fence device will be described with reference to FIGS. 3A and 3B.

<1> Normal time FIG. 3A shows a model diagram of the electric fence device in normal time.
In the figure, for ease of understanding, the divided bare electric wires 24 arranged in the divided sections 10a, 10b, ... are shown as single wires, and the intermediate struts 11b in the divided sections 10a, 10b, ... are omitted. are doing.

The power supply device 30 feeds through the main line 21 and the branch line 22 to divided bare electric wires 24 separately installed in the divided sections 10a, 10b, . . .
In a normal state when no contact with wild animals or electric leakage occurs in all of the divided sections 10a, 10b, . is supplied with an electric pulse.

In a normal state, the voltage sensor 26 measures a specific voltage for each divided section 10a, 10b, . . .
The voltage information for each section measured by the voltage sensor 26 is periodically transmitted to the administrator's receiving module through the communication module 27 .

<2> Invasion of wild animals FIG. 3B shows a model diagram of the electric fence device when wild animals try to invade part of the divided sections 10a, 10b, .

<2.1> Application of electric shock When a wild animal tries to enter a no-entry area such as a field or an orchard and comes into contact with the split bare wire 24 wired in a part of the split section 10c, for example, the ground and the split bare wire 24 An electric current is generated between them, and a strong electric shock is given to the wild animal.
When a wild animal repeatedly contacts the split bare wire 24, an electric shock is given each time.
Wild animals will give up entering the no-entry zone due to the painful learning effect, so the wild animals can be effectively eliminated.

<2.2> Influence on Other Divided Sections When a wild animal comes into contact with the divided bare wire 24 wired to a certain divided section 10c, the voltage of the divided section 10c temporarily changes greatly.
Since the resistors 23 are provided in all the divided sections 10a, 10b, . It does not affect .
Therefore, even if wild animals enter at the same time in a plurality of divided sections 10a, 10b, .

<2.3> Confirmation of Wild Animal Intrusion When a wild animal receives an electric shock in a part of the divided section 10c, the voltage of the divided section 10c temporarily changes significantly.

When an electric shock is given to an intruding wild animal, the voltage in a specific divided section 10c changes, and this voltage change is notified to the administrator through the voltage sensor 26 and the communication module 27. FIG.

Based on the voltage information of all divided sections 10a, 10b, . Section 10c) can be grasped instantly.
If the wild animal is a ferocious animal such as a bear, it is possible, if necessary, to directly go to a specific divided section 10c to exterminate the wild animal or set a trap for trapping.

<3> At the time of electric leakage FIG. 3B also serves as a model diagram of the electric fence device at the time of electric leakage.

Normally, in a conventional electric fence in which a continuous bare wire is connected to a single power supply, almost the same voltage is indicated at any position on the fence.
Therefore, in a conventional electric fence with a long distance, if an electric leakage occurs somewhere, it takes a long time to find the leakage point, and the voltage drops over the entire length of the bare wire, There was a problem that the function as an electric fence would deteriorate or fall into a loss of function.

<3.1> Affected Range of Electric Leakage On the other hand, in the present invention, resistors 23 are arranged in all divided sections 10a, 10b, 10c, . . . Even if an electric leakage occurs in a specific divided section 10c, the other divided sections 10a, 10b, 10d, . . . are not affected by the electric leakage.
In other words, the influence of the electric leakage is limited to the specific divided section 10c where the electric leakage occurs, and the other divided sections 10a, 10b, 10d, .
Therefore, it is possible to maintain the function as an electric fence in all the divided sections except for the divided section 10c where electric leakage occurred.

<3.2> Leakage Occurrence Position When an electric leak occurs in a part of the divided section 10c, the voltage sensor 26 detects the voltage drop in the section 10c, and the communication module 27 manages the occurrence of the electric leakage in the specific divided section 10c. notify the person.
Thereby, the administrator can grasp the occurrence of the electric leakage and the location of the occurrence of the electric leakage (specific divided section 10c).

<3.3> Confirmation and Restoration of Leakage In the present invention, a resistor 23 is interposed in a part of the branch line 22, and a split bare wire 24 is wired at the end of the resistor 23, thereby forming one power supply device. 30, a situation can be created in which a unique voltage is measured for each divided section 10a, 10b, . . . (for each branch line 22).
Since the administrator can specify the approximate position (the specific divided section 10c) where the electric leakage occurred, there is no need to investigate including the non-leakage section.
Therefore, it is possible to find the leakage point in the specific divided section 10c in a short time.

The administrator removes the cause of the electric leakage and restores the specific divided section 10c.
If the cause of electric leakage is contact with grasses, the specific divided section 10c can be quickly restored by removing the grasses.

In the present invention, leakage control is performed by utilizing the fact that each divided section 10a, 10b, . . . indicates a unique voltage.
Therefore, in order to maintain the function of the electric fence, it is no longer necessary to periodically look around the entire circumference of the fence or to remove grass more than necessary. Labor, time and cost can be greatly reduced.

<4> At Short Circuit When a short circuit occurs in the divided bare wires 24 of some of the divided sections 10a, 10b, . . .

For example, even if a short circuit occurs in the divided bare wires 24 of some divided sections 10c and the voltage drops to approximately 0 V, the effect of the short circuit is suppressed only in the specific divided sections 10c, and the other divided sections 10a, 10b, 10d, . . . are not affected by a short circuit.
Therefore, all the division|segmentation except the specific division|segmentation division 10c which short circuit generate|occur|produced can continue and maintain the function as an electric fence.

Via the voltage sensor 26 and the communication module 27, the occurrence of a short circuit in the specific divided section 10c and the location of the short circuit occurrence (the specific divided section 10c) are notified to the administrator's receiving module (not shown).
If necessary, the manager goes directly to the location of the short circuit and confirms the short circuit.
If the cause of the short circuit is an electrical short circuit, the cause of the short circuit is eliminated and the specific divided section 10c is restored.

In this example, by interposing a separator 15 made of an insulating material between the two wire fittings 14, 14, the adjacent divided bare electric wires 24, 24 are divided while sharing the boundary strut 11a.

FIG. 4(b) shows a configuration in which adjacent divided bare electric wires 24 are divided without sharing the boundary strut 11a.
In this example, adjacent divided bare electric wires 24, 24 are separated by using a pair of independent boundary struts 11a for each divided section 10a, 10b, . . . .
