  Hereinafter, a first embodiment of the harmful animal invasion prevention system of the present invention will be described with reference to FIGS. The harmful animal intrusion prevention system 10 of this embodiment is a system installed to protect a mountainous village from harmful animals such as wild boar. For example, the village shown in FIG. 1 is located inside the harmful animal habitat area YA in which harmful animals inhabit, and almost all of the village including a plurality of fields T, houses J, and living roads SD is a protected area HA. .. In addition, an internal/external road ND that connects the inside and the outside of the protected area HA crosses this village. The inside/outside road ND is a main road leading to other neighboring villages, and is a relatively large road through which pedestrians, bicycles, and automobiles (two-wheeled and four-wheeled) pass.

  The harmful animal invasion prevention system 10 is provided with an electric fence 12 that partitions the harmful animal inhabiting area YA and the protected area HA and blocks harmful animals from entering the protected area HA. In order to pass the inside/outside traffic road ND, the passages 14 are provided at two locations on the electric fence 12, and the gate device 16 is installed at each passage 14.

  As shown in FIG. 2, the electric fence 12 is provided by arranging two bare electric wires 12a on a large number of columns and attaching an electric shock means (not shown). When the number of the bare wires 12a is two, it is preferable that the bare wires 12a are installed at a height of about 20 cm and about 40 cm. With this height, a harmful animal such as a boar cannot jump over or pass through it, and moreover, when the harmful animal comes into contact with it, an electric shock can be appropriately applied. The number of bare wires 12a may be increased to three or more.

  The gate device 16 includes an opening/closing member 18 that blocks passage of harmful animals and humans in a closed state, and a drive mechanism 20 that drives the opening/closing member 18 to open and close. The opening/closing member 18 includes a rod-shaped right opening/closing member 18a that opens and closes the right side region inside the passage 14, and a rod-shaped left opening and closing member 18b that opens and closes the left side region. Three right opening/closing members 18a and three left opening/closing members 18b are provided, one on the upper side is arranged at a height of about 130 cm, and two on the lower side are arranged at a height extending the bare wire 12a. Then, in order to give an electric shock to the harmful beast that has come into contact with the lower two, electric shock means (not shown) similar to the electric fence 12 is attached. The material of the right opening/closing member 18a and the left opening/closing member 18b may be a metal, or may be a material other than a metal having a certain degree of shape stability. For example, if carbon fibers having conductivity are used, the weight can be reduced, and the electric shock means can be simply configured.

  The drive mechanism 20 includes a right drive mechanism 20a installed on the right side of the passage opening 14 for driving the right opening/closing member 18a and a left drive mechanism installed on the left side of the passage opening 14 for opening/closing the left opening/closing member 18b. 20b and. The right drive mechanism 20a supports one end of the right opening/closing member 18a, tilts the right opening/closing member 18a horizontally to a closed state, and raises it vertically to open it. Similarly, the left drive mechanism 20b supports one end portion of the left opening/closing member 18b, horizontally tilts the left opening/closing member 18a to a closed state, and vertically raises it to an open state. In the drive mechanism 20 (20a, 20b), for example, the opening/closing member 18 is biased to an open state by a spring or the like, and when changing from the open state to the closed state, the left and right opening/closing members 18a, 18b are powered by using a motor or the like. Is horizontally tilted, and the left and right opening/closing members 18a and 18b are held by, for example, holding metal fittings. On the contrary, when the opening/closing member 18 is changed from the closed state to the open state, it is preferable that the holding member or the like releases the holding and the opening/closing member 18 is quickly opened by using the force of the spring or the like. The structure for opening and closing the left and right opening/closing members 18a and 18b is preferably a structure for opening and closing by rotating in the vertical direction as described above, but a structure for opening and closing by rotating in the horizontal direction is also possible. Is.

  A first passerby detection device 22 is installed near the left drive mechanism 20b to detect a person approaching the passport 14 from the protected area HA side while distinguishing it from a harmful beast. The first passer-by detection device 22 detects humans and automobiles by attaching the non-contact type sensors 22a and 22b to separate columns and installing them at a position slightly distant from the passport 14 and a position very close to them. It is possible. The sensors 22a and 22b are, for example, distance sensors that irradiate light in the horizontal direction and receive reflected light to detect changes in the distance to the target object. It is fixed at a height that can detect both of the cars it drives. The first passer-by detection device 22 detects that "human beings" are detected when one of the sensors 22a and 22b detects an object, that is, when a pedestrian, a pedestrian or a person riding a bicycle, or a car driven by a person is detected. Was detected.”

  In the vicinity of the right drive mechanism 20a, a second passerby detection device 24 is installed which detects a person approaching the passageway 14 from the harmful beast habitat area YA side, separately from the harmful beast. The second passer-by detection device 24 is provided by attaching the non-contact type sensors 24a and 24b to separate columns and installing them at a position slightly distant from the passport 14 and a position very close to them. The sensors 24a and 24b are also the above-described distance sensors and the like, and like the sensor 22a, they are fixed at a height that cannot detect a low-profile harmful beast and can detect humans and automobiles driven by humans. The second passer-by detecting device 24 "detects a human" when the sensors 24a and 24b detect an object, that is, a pedestrian, a person who rides a bicycle or a bicycle, or an automobile driven by the person. To determine.

  Further, the gate device 16 is provided with a control device 26 that controls the operation of the drive mechanism 20 based on the detection results of the first and second passerby detection devices 22 and 24. The controller 26 includes a right controller 26a installed on the right side of the passage 14 for controlling the operation of the right drive mechanism 20a and a left installed on the left side of the passage 14 for controlling the operation of the left drive mechanism 20b. It is composed of a control device 26b. The right control device 26a and the left control device 26b are installed at positions separated from each other with the inside/outside traffic road ND interposed therebetween, and therefore wired or wireless communication means are provided for each, and the first and second passerby detection devices 22 are provided. , 24, the information such as the detection result can be shared with each other. When a wired communication means is provided, the communication cable is preferably buried in the ground. The control device 26 controls the opening/closing member 18 to be in the open state when the first state or the second passerby detection device 22, 24 detects a person, with the initial state of the opening/closing member 18 being in the closed state. When no human is detected, the opening/closing member 18 is controlled to return to the initial state.

  In addition, the gate device 16 is provided with two solar power generation devices 28a and 28b in order to secure a power supply for operating each device. The solar power generation device 28a installed on the right side of the passage 14 supplies operation power to the electric shock device of the right opening/closing member 18a, the right drive device 20a, the second passerby detection device 24, and the right control device 26a. To do. In addition, the solar power generation device 28b installed on the left side of the passage 14 is a power supply for operation toward the electric shock device of the left opening/closing member 18b, the left drive device 20b, the first passerby detection device 22 and the left control device 26b. To supply. It should be noted that only one solar power generation device may be installed on one side, and power may be supplied to the device installed on the other side through a cable buried in the ground.

  Next, an example of the operation of the harmful animal invasion prevention system 10 will be described with reference to the flowchart of FIG. First, the control device 26 closes the opening/closing member 18. This is the initial state, and the harmful beast intrusion prevention system 10 is constantly kept in a state in which harmful beasts are prevented from entering and humans cannot pass through (step S11).

  In the initial state of step S11, for example, as shown in FIG. 4, when a person (for example, a car JI or a pedestrian driven by a person) approaches the passage 14 from the protected area HA side, the sensors 22a and 22b detect this. Upon sensing, the first passer-by detection device 22 determines that "a person has been detected" (step S12). Then, before the automobile JI or the pedestrian hits the opening/closing member 18, the control device 20 promptly opens the opening/closing member 18 (step S13). As a result, the passage opening 14 is automatically opened, and the vehicle waits for a certain period of time in this state (step S14).

  After waiting for a certain period of time in step S14, the determination contents of the first and second passerby detection devices 22 and 24 are confirmed again (step S15). When one of the first and second passerby detection devices 22 and 24 determines that "a person has been detected", it means that the person is in the process of passing through the passageway 14, so that the process proceeds to step S14. Returning to this, the control device 26 holds the opening/closing member 18 in the open state.

  After that, when a person completely passes through the passage 14, both the first and second passerby detection devices 22 and 24 determine that "a person is not detected". Therefore, the process proceeds to step S11, and the control device 26 opens and closes. The member 18 is returned to the closed state (initial state). With this, a human can smoothly enter the harmful beast habitat area YA. The operation when the human approaches from the harmful beast habitat area YA side is similar, and the human can smoothly enter the protected area HA.

  In the initial state of step S11, when a harmful beast that lives in the harmful beast habitat area YA approaches the passage 14, a low-profile harmful beast such as a boar is not detected by the sensors 24a and 24b, and the opening/closing member 18 is closed. Since it is kept in the state (initial state), the harmful beast cannot enter the protected area HA. Further, since harmful animals such as wild boars have a strong alertness and have a property of not approaching humans, there is no possibility that harmful animals will pass through with the human when passing through the open passageway 14.

  As described above, the harmful animal invasion prevention system 10 is a large-scale system that protects a specific area including a plurality of fields, a village, etc., by enclosing it with one electric fence 12, so that a small system as in the past can be used. The total cost can be significantly reduced compared to installing multiple units. In addition, there is a passageway 14 for passing the inside and outside passageway ND in the middle of the electric fence 12, but since a gate device 16 having a unique configuration is installed at the passageway 14, harmful animals are protected from the passageway 14 through the protected area. Pedestrians and automobiles can smoothly pass through the passage 14 without being able to enter the HA.

  Next, a second embodiment of the harmful animal intrusion prevention system of the present invention will be described with reference to FIGS. 1 and 5 to 7. Here, the same components as those of the above-described harmful animal intrusion prevention system 10 are designated by the same reference numerals, and description thereof will be omitted. As shown in FIG. 1, the harmful animal invasion prevention system 30 of this embodiment divides a harmful animal habitat area YA and a protected area HA, and a harmful animal in the harmful animal habitat area YA enters the protected area HA. It is a system to prevent. The difference between the harmful animal intrusion prevention system 30 and the harmful animal invasion prevention system 10 is that a gate device 32 different from the gate device 16 is installed at the passage 14 of the electric fence 12.

  The gate device 32 includes an opening/closing member 34 that blocks passage of harmful animals and humans in a closed state, and a drive mechanism 36 that drives the opening/closing member 34 to open and close. The opening/closing member 34 forms a passage blocking surface 34c by tensioning two bare wires 34b between a pair of left and right bar members 34a. The opening/closing member 34 is rotatably supported by the lower ends of the pair of rod members 34a, and has a structure in which the passage blocking surface 34c stands or falls on the inside/outside road ND. In the opened state of the member 34, the upright state is the closed state of the opening/closing member 34.

  The bare wire 34b is arranged at a height obtained by extending the bare wire 12a of the electric fence 12 when the opening/closing member 34 is in the closed state. To the bare wire 34a, an electric shock means (not shown) similar to that of the electric fence 12 is attached in order to give an electric shock to the contacting harmful beast. When the opening/closing member 34 is in the open state, the bare wire 34a may come into contact with the ground, a wasteful current may flow to the ground, and the voltage of the electric shock means may drop. In this case, it is preferable that the electric shock output is stopped.

  The drive mechanism 36 is installed on the right side of the passage 14 for driving the right rod member 34a of the opening/closing member 34, and on the left side of the passage 14 for driving the left rod member 34a. And a left drive mechanism 36b. The drive mechanism 36 (36a, 36b) uses, for example, the power of a motor or the like to raise the rod member 34a in the vertical direction when the opening/closing member 34 is changed from the open state to the closed state, and the rod member 34a is held by a holding metal fitting or the like. Hold. Then, when the open/close member 34 is changed from the closed state to the open state, the holding by the holding metal fitting or the like is released, and the open/close member 34 is biased in the horizontal direction by the spring or the like so that the open/close member 34 has its own weight or the force of the spring or the like. A simple structure that can be quickly collapsed by using.

  In the vicinity of the drive mechanism 36 (36a, 36b), a first passerby detection device 38 that detects humans and harmful beasts approaching the passport 14 from the protected area HA side is installed. The first passer-by detection device 38 includes non-contact low-place sensors 38a and 38b attached to two columns, and a push button device 38c attached to another column. The low-position sensors 38a and 38b are distance sensors similar to the above-mentioned sensors 22a and 22b, but are fixed to a height that can detect not only pedestrians and automobiles driven by humans but also low-profile harmful beasts. There is a feature that is being done. The push button device 38c is provided so that a person approaching the passageway 14 can manually operate it. Then, the first passer-by detection device 38 determines that "a human or a harmful beast has been detected" when either of the low place sensors 38a and 38b senses an object. Further, when the push button device 38c is operated, it is determined that "a human is detected". In this embodiment, since the process after determining that “a human or a harmful beast has been detected” is the same as the process after determining that “a human has been detected”, the first passerby detection device 38 Does not distinguish between the two decisions. The details of the determination process will be described later.

  Further, in the vicinity of the drive mechanism 36 (36a, 36b), a second passerby detection device 40 is installed which detects a person approaching the passageway 14 from the harmful beast habitat area YA, separately from the harmful beast. There is. The second passer-by detection device 40 includes non-contact type height sensors 40a and 40b attached to two columns and a push button device 40c attached to another column. The height sensors 40a and 40b are distance sensors and the like similar to the above-mentioned sensors 22a and 22b, and are fixed to a height at which a low-profile harmful beast cannot be detected and a pedestrian and a human-driving car can be detected. There is. The push button device 40c is provided so that a person approaching the passageway 14 can manually operate it. Then, the second passer-by detection device 32 determines that "a human is detected" when either of the height sensors 40a and 40b senses an object. Also, when the push button device 40c is operated, it is determined that "a human is detected".

  Further, the gate device 32 is provided with a control device 42 that controls the operation of the drive mechanism 36 based on the detection results of the first and second passerby detection devices 38 and 40. The controller 42 includes a right controller 42a installed on the right side of the passage 14 for controlling the operation of the right drive mechanism 36a and a left installed on the left side of the passage 14 for controlling the operation of the left drive mechanism 36b. It is composed of a control device 42b. The right control device 42a and the left control device 42b are installed at positions distant from each other with the inside/outside traffic road ND interposed therebetween, so that a wired or wireless communication means is provided for each of them, and the first and second passerby detection devices 38 are provided. , 40, and the information such as the detection results can be shared with each other. The control device 42 closes the initial state of the opening/closing member 34, and controls the opening/closing member 34 to be in the open state when a human or a harmful beast is detected by the first or second passerby detection device 38, 40. After that, when the human or the harmful beast is no longer detected, the opening/closing member 34 is returned to the initial state.

  Further, the alerting means 34 is installed on the column to which the drive mechanism 36 (36a, 36b) is attached, and when the opening/closing member 18 is in the closed state, the opening/closing member 18 is closed to a person approaching the passage 14. You can see that it is in a state. The alerting means 44 has a rod member that is displaced like the opening/closing member 18 shown in FIG. 2, and a flag for alerting is attached to this rod member. When the opening/closing member 34 is in the closed state, the alerting means 44 causes the rod member to fall down in the horizontal direction so that the flag can be easily seen, and alerts the people around to visually recognize the flag. Then, when the opening/closing member 34 is in the open state, as shown in FIG. 7, the rod member stands upright and retracts to a position where the flag is difficult to see. The bar member of the alerting means 44 may be configured to hang downward in the vertical direction and retract. By providing the alerting means 44, it is possible to prevent an accident in which a fast automobile or the like accidentally collides with the opening/closing member 34. In addition, the gate device 32 is provided with the same solar power generation devices 28a and 28b as described above in order to secure a power supply for operating each device.

  Next, an example of the operation of the harmful beast intrusion prevention system 30 will be described with reference to the flowchart of FIG. First, the controller 42 closes the opening/closing member 34. This is the initial state, and the harmful beast intrusion prevention system 30 is constantly kept in a state in which harmful beasts are prevented from entering and humans cannot pass through (step S21).

  In the initial state of step S21, for example, as shown in FIG. 7, a person (for example, a car JI or a pedestrian driven by a person) approaches the passageway 14 from the protected area HA side, and the low-place sensors 38a and 38b move this. Upon sensing, the first passer-by detection device 38 determines that "a human or a harmful animal has been detected" (step S22). Then, before the person or the automobile JI hits the opening/closing member 34, the control device 20 immediately opens the opening/closing member 34 (step S23). As a result, the passage 14 is automatically opened, and the vehicle waits for a certain period of time in this state (step S24).

  Further, when the harmful beast is lost in the protected area HA for some reason, even when the harmful beast approaches the passage 14, it is sensed by the low place sensors 38a and 38b, and steps S22 to S24 are performed. .. After waiting for a certain period of time in step S24, the determination contents of the first and second passerby detection devices 38 and 40 are confirmed again (step S25). When one of the first and second passerby detection devices 38 and 40 determines that “a human or a harmful beast has been detected”, a human or a harmful beast is passing through the passageway 14. Since it is in the middle, the process returns to step S24, and the control device 42 holds the opening/closing member 34 in the open state.

  After that, when the human or the harmful beast completely passes through the passage 14, both the first and second passerby detection devices 38 and 40 determine that "the human or the harmful beast is not detected", and thus the process proceeds to step S21. The control device 42 returns the opening/closing member 34 to the closed state (initial state). With this, the human can smoothly enter the harmful animal habitat area YA, and further, the lost harmful animal can be automatically driven to the harmful animal habitat area YA.

  On the contrary, when a human or a harmful animal approaches the passage 14 from the harmful animal habitat area YA side, the operation is different. When a person approaches, it is sensed by the height sensors 40a and 40b in the same manner as described above, the above steps S22 to S24 are performed, and the protected area HA can be smoothly entered. However, when a low-profile harmful beast such as a boar approaches, it is not sensed by the height sensors 40a and 40b, and the opening/closing member 34 is held in the closed state (initial state). Can not break into.

  In addition, in the case of a human, the opening/closing device 34 can be opened by manually operating the push button devices 38c and 40c. For example, in the initial state of step S21, when a person approaches the passage 14 and operates the push button device 38c or 40c, the first passerby detection device 38 or 40 determines that "a person has been detected" ( In step S26), the control device 42 promptly opens the opening/closing member 34 (step S23).

  Then, similarly to the above, the process waits for a certain time in step S24, and the determination contents of the first and second passerby detection devices 38 and 40 are confirmed again (step S25). When a person is passing through the passage 14, one of the sensors 38a, 38b, 40a, 40b senses the person, and one of the first and second passerby detection devices 38, 40 indicates " Since it is determined that a human or a harmful animal has been detected”, the process returns to step S24, and the control device 42 holds the opening/closing member 34 in the open state. After that, when the human or the harmful beast completely passes through the passage 14, both the first and second passerby detection devices 38 and 40 determine that "the human or the harmful beast is not detected", and thus the process proceeds to step S21. The control device 42 returns the opening/closing member 34 to the closed state (initial state). With this, a person can smoothly pass through the passage 14.

  In the case of the first and second passerby detection devices 22 and 24 shown in FIG. 2, since the pushbutton device is not provided, when a person approaches the passport 14, the sensors 22a, 22b, 24a, If the person 24b cannot detect a person, the opening/closing member is held in a closed state, and the person cannot pass and is stopped. On the other hand, in the case of the first and second passerby detection devices 38 and 40 of this embodiment, since the push button devices 38c and 40c are provided, even if such a situation arises, the person Can pass without any hindrance.

  As described above, according to the harmful animal intrusion prevention system 30, the same excellent effects as those of the harmful animal invasion prevention system 10 can be obtained. Further, when the harmful beast has strayed into the protected area HA for some reason and the harmful beast comes near the passage opening 14, the first passerby detection means 38 detects the harmful beast, and the opening/closing device 34 is set. Since it is in the open state, the stray pest can be automatically expelled to the pest habitation area YA. Further, since the push button devices 38c and 40c are provided, even if the sensor cannot detect the person for some reason, it is possible to avoid the situation where the person is stopped. Further, since the alerting means 44 is provided, it is possible to prevent an accident in which a fast automobile or the like accidentally collides with the opening/closing member 18.

  Next, a third embodiment of the harmful animal invasion prevention system of the present invention will be described with reference to FIGS. 1 and 8 to 9. Here, the same components as those of the above-described harmful animal intrusion prevention system 10 are designated by the same reference numerals, and description thereof will be omitted. The harmful animal invasion prevention system 46 of this embodiment divides a harmful animal habitat area YA and a protected area HA as shown in FIG. 1, and a harmful animal in the harmful animal habitat area YA enters the protected area HA. It is a system to prevent. A difference between the harmful animal invasion prevention system 46 and the harmful animal invasion prevention system 10 is that a gate device 48 different from that of the above-described embodiment is installed at the passage 14 of the electric fence 12.

  As shown in FIG. 8, the gate device 48 includes the opening/closing member 18, the drive mechanism 20, and the solar power generation devices 28a and 28b similar to the above, and a passer-by detection device 50 and a control device 52 different from the above. ing.

  The passerby detection device 50 is a device that detects a harmful beast approaching the passageway 14 from the harmful beast habitat area YA side separately from a human, and is installed in the vicinity of the left drive mechanism 20b here. The passerby detection device 50 has a structure in which a height sensor 50a such as a distance sensor and a low height sensor 50b are attached to one pillar. The high-altitude sensor 50a is fixed to a height that cannot detect low-profile harmful beasts and can detect vehicles that pedestrians and humans drive, and the low-altitude sensor 50b can detect vehicles that pedestrians and humans drive. Not only that, it is fixed at a height that can detect low-profile pests.

  The passerby detection device 50 determines whether a harmful beast or a human is detected based on the detection results of the high-altitude sensor 50a and the low-altitude sensor 50b. As shown in FIG. 9A, there are three types of determination. For example, when neither the high-altitude sensor 50a nor the low-altitude sensor 50b senses an object, it is determined that "nothing is detected" (type 1). When only the low-place sensor 50b senses an object, it is determined that "a harmful beast has been detected" (type 2). When both the high-altitude sensor 50a and the low-altitude sensor 50b sense an object, it is determined that "a human is detected" (type 3).

  The control device 52 is a device that controls the operation of the drive mechanism 20 based on the detection result of the passerby detection device 50, and includes a right control device 52a installed on the right side of the passage 14 for controlling the right drive mechanism 20a. , A left control device 52b installed on the left side of the passage 14 for controlling the left drive mechanism 20b. Since the right control device 52a and the left control device 52b are installed at positions distant from each other with the inside/outside traffic road ND interposed therebetween, a wired or wireless communication means is provided for each, and information such as the detection result of the passerby detection device 50 is provided. Can be shared with each other. The control device 52 opens the opening/closing member 18 in the initial state, and when the passerby detection device 50 detects a harmful beast, controls the opening/closing member 18 to be in a closed state, and thereafter the harmful beast is not detected. Then, control for returning the opening/closing member 18 to the initial state is performed.

  Next, an example of the operation of the harmful beast intrusion prevention system 36 will be described with reference to the flowchart of FIG. First, the controller 52 closes the opening/closing member 18 (step S31). This is the initial state, and the harmful animal invasion prevention system 36 is constantly kept in a state in which humans can pass without hindrance but the invasion of harmful animals cannot be blocked.

  In the initial state of step S31, when a low-profile pest such as a boar approaches the passage 14 from the pest habitation area YA side, only the low-place sensor 50b senses an object, and the passerby detection device 40 makes a determination. Changes from type 1 to type 2. Then, the process proceeds to step S34 via steps S32 and S33, and the control device 52 closes the opening/closing member 18 and keeps this closed state for a certain period of time. As a result, the passage 14 is automatically closed, and harmful animals cannot enter the protected area HA.

  After that, when the harmful beast gives up the invasion and moves away from the passage 14, both the high-altitude sensor 50a and the low-altitude sensor 50b no longer detect the object, and the determination of the passerby detection device 50 is changed from type 2 to type 1. Change. Then, the process proceeds to step S31 via steps S32 and S33, and the control device 50 returns the opening/closing member 18 to the open state (initial state). On the other hand, if the determination does not change from type 2 in step S32, it means that the harmful beast is still near the passageway 14, so the opening/closing member 18 is held in the closed state.

  In the initial state of step S31, when a human (pedestrian or automobile) approaches the passage 14 from the harmful beast habitat area YA side, both the high-altitude sensor 50a and the low-altitude sensor 50b sense an object, and the passerby is detected. The determination of the detection device 50 changes from type 1 to type 3. Then, the process proceeds to step S31 through steps S32 and S33, the opening/closing member 18 is held in the open state (initial state), and a pedestrian or the like can enter the protected area YA without any trouble.

  Then, when a person passes through the passage 14, both the high-altitude sensor 50a and the low-altitude sensor 50b no longer sense the object, and the determination made by the passer-by detection device 50 changes from type 3 to type 1. Then, the process proceeds to step S31 through steps S32 and S33, and the opening/closing member 18 is held in the open state (initial state).

  After step S31, when a person approaches the passage 14 from the protected area HA side, the person is not detected by the high-altitude sensor 50a and the low-altitude sensor 50b and can pass through the open passage 14 without trouble. Then, after passing through the passage 14, both of the high-altitude sensor 50a and the low-altitude sensor 50b detect the determination of the passerby detection device 50 from type 1 to type 3, but through steps S32 and S33, In S31, the opening/closing member 18 is held in the open state (initial state).

  In this way, the harmful animal invasion prevention system 46 can also obtain the same excellent effects as those of the harmful animal invader system 10. The gate device 48 of this embodiment may be replaced with the gate device 32 of the above-described embodiment so that the opening/closing member 34 is always open and the opening/closing member 34 rises and closes when a harmful animal is detected.

  The harmful animal intrusion prevention system of the present invention is not limited to the above embodiment. For example, in the above-described harmful animal intrusion prevention systems 10 and 46, since the width of the inside and outside roads is wide, it is necessary to disperse the load applied to the opening/closing member of the gate device and the driving device. It is divided into left and right. However, when the width of the inside and outside roads is narrow, it is not necessary to distribute the load, so that it is possible to install only one set on one side without dividing into left and right. The words right/left mean that they are on the opposite sides of the inside and outside road, and right/left may be collectively read as left/right.

  The opening/closing member 18 shown in FIG. 2 and the opening/closing member 34 shown in FIG. 5 exemplify preferable configurations of the opening/closing member, but can be changed to different configurations as long as the same action and effect can be obtained. . The same applies to the configuration of the electric shock device attached to the opening/closing member. Further, in order to more effectively give an electric shock to the harmful beast, a conductive paint, a wire net, a conductive concrete or the like may be laid on the ground near the opening/closing member (the upper surface of the inside/outside road).

The distance sensor as described above is suitable for the non-contact type sensor attached to the passerby detection device, but it may be changed to another sensor such as an infrared sensor or an ultrasonic sensor.
Although the first and second passerby detection devices 22 and 24 shown in FIG. 2 do not have push button devices, push button devices 38c and 40c shown in FIG. 5 may be added. Further, when the frequency of passage of an automobile is low, it is possible to omit the sensors 22a, 22b, 24a, 24b and use only the push button devices 38c, 40c. In this case, when the vehicle approaches the passage 14, the vehicle is stopped near the push button devices 38c and 40c, and the driver or the like manually operates the push button device 32b. Further, although the first and second passerby detection devices 38 and 40 shown in FIG. 5 have push button devices 38c and 40c, these can be omitted if not necessary.

  The button devices 38c and 40c are configured to perform only an operation (an operation for changing the open/close member in the closed state to the open state) for notifying that a person has approached the passageway 14. The control for returning to the closed state is performed based on the detection result of the sensor. Therefore, when the sensor is omitted and only the push button devices 38c and 40c are provided, for example, an operation for notifying that the person approaches the passage 14 (operation for changing the open/close member in the closed state to the open state) is performed. After the execution, it is preferable to perform control such that the opening/closing member is automatically returned to the closed state at a timing when a time sufficient for a person to pass by on foot has passed. Alternatively, the operation of changing the configuration of the push button device to notify that a person is approaching the passage (operation for changing the open/close member in the closed state to the open state) and the operation of informing that the person has passed through the passage (open/close) Both of the operations for returning the member to the closed state) may be performed.

  In addition, the structure of the electric fence is not particularly limited, and may be a structure in which a plurality of bare electric wires as described above are erected on a pillar, or, for example, a structure in which a wire net is stretched around. Further, the protected area is not limited in size and shape as long as it can be partitioned by an electric fence. Therefore, the harmful animal invasion prevention system of the present invention can be installed not only in a mountain village but also in various places and areas.

  Assuming that the vehicle hits before the opening/closing member opens, it is desirable that the opening/closing member that opens vertically has a mechanism that bends in the traveling direction of the vehicle. Further, it is desirable that the electric wire opening/closing member has a mechanism for separating the electric wire from the rod member when a force of a certain level or more is applied. This can prevent the opening/closing member from being damaged. In addition, assuming that the switchgear fails, it is desirable to have a mechanism that can always open the switchgear so that the switchgear does not obstruct the passage. It is recommended to install it near the switchgear. This prevents the opening/closing member from becoming a traffic obstacle even in the unlikely event of a failure.
