Description

  The present invention is connected to an electric fence for preventing the invasion of pests (hereinafter referred to as “electric fence”) installed around the field in order to prevent the infestation of pests such as cormorants and deer into the field. More particularly, the present invention relates to an electric fence power supply device (hereinafter referred to as “power supply device”) having an electric supply circuit for preventing theft.

  In order to prevent harmful beasts such as spiders, monkeys, and deers from entering the fields, the electric fences run around the bare wires around the fields and apply an electric shock shock voltage to the bare wires. A power supply device is connected to flow electricity. Harmful animals such as spiders, monkeys, and deers trying to invade the fields cannot touch the fields because they touch the bare wires and receive a strong electric shock. In this way, the field is protected from the damage caused by harmful animals (see Patent Documents 1 to 5).

However, power supply devices are often stolen for the following reasons. (1) It has a definite anti-invasion effect on beasts such as spiders and deer. (2) Many power supply devices are installed outdoors. (3) Installed in a place where there are few people. (4) It can be easily removed simply by turning off the switch and disconnecting the wire connected to the electric fence. (5) The power supply is small and light and easy to carry. (6) The stolen power supply can be used again as long as it is switched on. (7) It is difficult to determine whether a stolen power supply is a stolen product. (8) The stolen power supply is sold as a used product.
For this reason, there are many requests from users of electric fences in various regions to prevent the power supply device from being stolen.

The following two methods can be considered for theft prevention.
The first is to firmly fix the power supply so that it cannot move.
The second is to make the power supply unusable even if it is stolen. If the second method is used, the reason for theft (6) cannot be reused, and the second-hand goods for the same reason (8) cannot be bought and sold, so theft can be prevented.

In order to prevent the theft of the power supply device, Patent Document 4 describes an engraving device that generates a high voltage on an electric fence, a battery that serves as a power source for the engraving device, an engraving device and a battery, and an outer peripheral portion that is grounded. An electric engraving unit built-in column for an electric fence provided with a column body that functions as
Further, in Patent Document 5, the main pile buried in the ground, a wire or chain member having one end connected to the base end side of the main pile, and a locking hole on the base end side of the main pile were inserted. An antitheft device comprising a lock that removably couples the other end of a fixed pile, wire or chain member buried in the ground in a state and an electric fence main body for supplying an impact voltage to a bare electric wire of the electric fence Are listed.

JP 2007-175007 A JP 2005-151748 A JP 2004-000063 A JP 2009-022246 A Utility Model Registration No. 3149862

In the engraving machine built-in column body of the cited document 4, the pillar is removed from the ground and stolen, and can be used again. Therefore, an antitheft effect cannot be expected. In addition, there is a need for a pole to house the electric engraving machine and the battery, and the structure is complicated due to the operation of the electric engraving machine and the battery inside the pole, and the operation from the outside of the pole of the electric engraving machine. There is.
In the cited document 5, a power supply device that has been stolen by cutting a wire or chain member can be connected to an electric fence and can be reused, and does not prevent theft.

  Therefore, the present invention stops the alarm when the impact voltage generation circuit does not operate, does not generate an impact voltage, and generates an alarm so that the power supply device becomes unusable when it is stolen. Therefore, it is intended to provide a power supply device that cannot be used as an electric fence without generating an impact voltage and generating an impact voltage when the power supply is connected again even if the power supply is disconnected.

The power supply circuit for supplying electricity to the impact voltage generating circuit is connected between the power source and the impact voltage generating circuit for supplying the impact voltage to the electric fence for preventing pest invasion. The power supply circuit controls the supply of electricity to the impact voltage generation circuit, an open / close switch that switches the supply of electricity to “on” or “off”, and the normal mode for supplying electricity to the shock voltage generation circuit is changeover switch is connected to switch to the anti-theft mode, the power supply circuit is, in a state where the changeover switch is connected to the anti-theft mode, to generate electrical signals by switching off switch, this generated electrical signal, the shock voltage generator the circuit in a stopped state, then the power for an electric fence, characterized in that even if the switching-off switch is a circuit for maintaining the stopped state of the impact voltage generating circuit It is the location.

  The invention according to claim 2 is characterized in that the change-over switch is a switch in which a switch portion and an operation tool necessary for operation of the switch portion are separated from each other. It is.

  The power supply circuit for an electric fence according to claim 1 or 2, wherein the power supply circuit includes an alarm device that generates an alarm by the generated electric signal. is there.

The invention of claim 4, wherein the power supply circuit, is removed to connect the power source and the power supply circuit, when subsequently connected again to the power supply circuit, regardless of the state of the "filled" or "off" of the opening and closing switch The electric fence power supply device according to any one of claims 1 to 3, wherein the electric fence is a circuit that generates an electric signal.

  According to a fifth aspect of the present invention, the electric power supply circuit according to any one of the first to fourth aspects, further comprising a transmitter that transmits the radio wave generated by the electric signal to an external receiver. It is a power supply device for a fence.

  According to the first aspect of the present invention, when the changeover switch is connected to the normal mode, when the open / close switch is changed over, the changeover switch is not detected and no electrical signal is generated. When the open / close switch is switched in the state of being connected to, an electrical signal is generated upon sensing the “switch”. Due to the occurrence of this electrical signal, the stolen power supply device will not generate an impact voltage, and the thief or the person who has transferred this stolen power supply device will be disabled, preventing the power supply device from being stolen. I can do it.

  According to the invention of claim 2, since the changeover switch is separated into the operation tools necessary for operating the switch unit, the alarm device is driven to operate the open / close switch to generate an alarm sound. The criminal or the person who has transferred the stolen power supply device does not have the instrument to operate, so the alarm sound cannot be stopped and the normal state cannot be restored. Therefore, it cannot be used, and since it has no commercial value and cannot be bought and sold as a used product, it is effective in preventing theft.

  According to the invention of claim 3, theft can be prevented by driving an alarm device such as a warning sound or a warning lamp by the generated electric signal and issuing an alarm. In addition, the supply of power to the impact voltage generation circuit is stopped by the electrical signal.

  According to the invention of claim 4, even when the connection of the power supply to the power supply circuit is disconnected after the power supply circuit generates an electrical signal and then connected to the power supply circuit again, the on / off switch is turned on or off. ”Regardless of the status of the device, the alarm device is driven as in the previous period and the power supply is stopped to the impact voltage generator circuit. Because you can't, you can prevent theft.

  According to the fifth aspect of the present invention, it is possible to notify the remote place of theft by transmitting a radio wave by the generated electric signal and receiving it by the receiving unit of the monitoring device or the mobile phone.

It is a figure which shows the electric supply circuit which uses the relay of the power supply device of this invention. It is a time chart (the 1) of a circuit. It is a time chart (the 2) of a circuit. It is a time chart (the 3) of a circuit. It is a figure which shows the electric supply circuit of digital IC use. It is a figure which shows the electric supply circuit by a sequencer. It is a figure which shows the electric supply circuit containing a microcomputer. It is a figure which shows the electricity supply circuit which replaced with the switch with a key and used the proximity switch.

  The electric supply circuit of the present invention is based on the combination of the switch and the relay shown in FIG. 1, by the digital IC shown in FIG. 5, by the sequencer to which the switch with key shown in FIG. 6 is connected, and the key shown in FIG. An attached switch or the like can be constituted by a microcomputer connected thereto.

  The changeover switch is a switch for switching to a theft prevention mode for controlling the supply of electricity to the impact voltage generation circuit or a normal mode for supplying electricity to the impact voltage generation circuit. The changeover switch uses a switch, for example, a switch with a key, which is separated from an operation tool necessary for operation such as a switch main body and a key or a proximity switch. The switch with key is divided into a switch body and a key. A keyhole is dug in the switch body. When operating this switch with key, the key is inserted into the keyhole drilled in the switch body. This switch cannot be operated without inserting the key into the keyhole. The key is owned by the owner of the power supply.

  As the changeover switch, a proximity switch using magnetism shown in FIG. 8 may be used instead of the switch with key.

  If the owner of the electric fence power supply device keeps the magnetism generator part of the proximity switch, the same effect as the case of using the switch with the key occurs. Further, even if a switch other than the key switch and the proximity switch is used, a device other than the switch body is required to operate it, and the same effect can be generated if a portable type is used. For example, there are switches that can be turned on and off by special light beams, radio waves, sound waves and the like.

  In short, the switch body and the operation tools necessary for the operation such as the key and the proximity switch are separated, and any switch can be implemented as long as the switch body cannot be turned ON / OFF without using the operation tool.

Table 1 summarizes the contact points of the above relays.

Next, with reference to the time charts shown in FIGS. 2 to 4, the operation of the electricity supply circuit will be described for various cases.
2 to 4, the coil is H: excited, L: demagnetized, the contact is ◯: closed, X: open, P1, P2, P4, P6, P7 are H: potential, L: no potential (Zero potential).

(1) Case 1 (see time charts 1 to 5 in FIG. 2)
The virtual switch S0 is in an OFF state. Since the power supply is disconnected because the power supply is disconnected, BZ is silent regardless of whether the key switch KS is connected to T1 or T2, and the open / close switch S2 is ON or OFF. The generation circuit is in a stopped state.

(2) Case 2 (see time charts 6 to 10 in FIG. 2)
In the state of {S0 (fixed ON), KS (fixed T1), S2 (OFF → ON → OFF)}, the operators of S0, KS, and S2 are owners of the electric fence power supply device. In this state, the impact voltage generation circuit repeatedly operates and stops when S2 is turned on and off. All BZs are silent.
In the time charts 8 and 10, L3 becomes L with a delay. In the time charts 8 and 10, P4 is a short time H.

(3) Case 3 (see time charts 11 to 15 in FIG. 2)
In the state of {S0 (fixed ON), KS (T1 or T2), S2 (fixed OFF)}, the operators of S0, KS, and S2 are owners of the electric fence power supply device. In this state, even if KS is connected to T1 or T2, the impact voltage generating circuit is in a stopped state, and BZ is silent and there is no problem.
In the time charts 12 and 14, L1 is delayed to L, and in the time charts 13 and 15, L1 is delayed to H, and the delayed time is t10. Further, in the time charts 12 and 14, R1, C1, and C5 are selected so that t10> t50, where L5 is a short time H and the short time that L5 is H is t50.

(4) Case 4 (see time charts 17 to 20 in FIG. 3)
In the state of {S0 (fixed ON), KS (T1 or T2), S2 (fixed ON)}, the operators of S0, KS, and S2 are owners of the electric fence power supply device. In this state, even if KS is connected to T1 or T2, the impact voltage generation circuit operates and BZ is silent.
In the time charts 18 and 20, L1 is delayed to L, and in the time chart 19, L1 is delayed to H. In the time chart 17, L3 becomes H with a delay. In the time charts 18 and 20, L5 is a short time H.

(5) Case 5 (see time charts 21 to 26 in FIG. 3)
S0 (fixed to ON), KS (fixed from T1 to T2), S2 (OFF to ON)}, the operators of S0 and KS are the owners of the electric fence power supply device. In this case, the owner operates S2 first (see time charts 21 to 23), and then the thief operates (see time charts 24 to 26).

  (A) In the state where S0 is ON (the state where the power supply is connected), the owner of the electric fence power supply apparatus sets KS (T1 → T2 fixed) in the state of S2 (OFF), and then the owner uses S2 ( ON) (time chart 22 → 23). When S2 (ON) is reached, the impact voltage generation circuit is activated and BZ is silent. Thereafter, the owner removes the key from KS and stores it.

(B) Next, the thief tries to steal the electric fence power supply device and switches S2 from (ON) to (OFF) to stop the shock voltage generation circuit (time chart 23 → 24). At this time, L6 is held by itself, BZ is sounded, and the impact voltage generation circuit is stopped.
When a signal that sounds BZ is generated, this signal is guided to a radio wave transmitter, the radio wave is transmitted, the radio wave is received by a receiver installed at a remote location, demodulated in the receiver, and the electric fence power supply device is stolen. You can also know. The receiver may be a mobile phone.

(C) Once BZ is sounded in the state of (b) and the shock voltage generating circuit is stopped, even if the thief is surprised to turn S2 ON (time chart 25), BZ is sounded. Subsequently, the shock voltage generation circuit remains stopped. Even if it is further turned OFF (time chart 26), BZ continues to sound and the shock voltage generation circuit is stopped.
Note that when the key switch KS is switched from (T2 to T1), BZ becomes silent and the shock voltage generation circuit can be operated. However, since the thief cannot possess the key and cannot operate KS, BZ is pronounced. Subsequently, the shock voltage generating circuit is stopped.

(6) Case 6 (see time charts 27a to 30a in FIG. 4)
When the BZ sounding and impact voltage generating circuit is stopped in (b) to (c) of (5), the thief is in a state of removing the power supply.

  (A) If the thief tries to silence the BZ sound of the electric fence power supply device and disconnects the battery as the power source from the power supply device (in the case of S0 (OFF)), the power supply is completely lost. Naturally, BZ becomes silent, and the impact voltage generation circuit is stopped (see time chart 28a, same as time chart 3 above).

(B) However, when the power source is disconnected after the power source is removed in (a) (in the case of S0 (ON)), L6 is self-maintained, regardless of whether S2 is OFF or ON (time Charts 29a and 30a) and BZ indicate sound generation, and the impact voltage generation circuit is in a stopped state.
Thus, the power supply device cannot be used again. Therefore, the thief cannot use it by himself, and even if he tries to resell it to another person, it cannot be used because it is unusable and has no value.

(7) Case 7 (see time charts 27b to 30b in FIG. 4)
This is for returning the BZ sounding and impact voltage generating circuit from the stopped state to the normal state.
The owner of the electric fence power supply storing the KS key goes to the electric fence power supply where the power supply is installed by holding the key by BZ pronunciation or theft notification by the receiver. And the stop state of the shock voltage generation circuit is confirmed (time chart 27b)

  (A) A key is inserted into the key type switch KS and switched from T2 to T1. Then, BZ is silent and returns to a state where the impact voltage generating circuit can be operated (time chart 28b, returning to the state of (2)).

(B) When S2 is switched ON or OFF, a normal state is reached in which the impact voltage generation circuit is activated and stopped without sounding BZ (time charts 29b and 30b).
Thus, if KS is fixed at (T1) as described above, the impact voltage generating circuit operates normally and BZ is silent. If KS is fixed at (T2), the impact voltage generating circuit is stopped at S2 (ON → OFF) and BZ is sounded. Thereafter, even if S2 is turned ON or OFF, the state does not change. Further, when the power supply is removed from this state and then the power supply is connected again, the shock voltage generating circuit is stopped and BZ is in a sounding state.
