Hereinafter, preferred embodiments of the present invention will be described. Needless to say, the present invention is not limited to the following embodiments. The present invention is practiced in various aspects within the scope of the technical ideas disclosed herein. The components common to the embodiments have the same reference numerals.

(Appearance of mouse capture device)
FIG. 1 is a front view of the mouse catching device 10. The mouse catching device 10 is manufactured by being incorporated in a trash can. The mouse catching device 10 includes a trash can main body 11 and a plurality of removable catching boxes 12. The mouse catching device 10 is installed in a site where a large number of people come and go, such as a railway station yard, a commercial facility, or an athletic facility.

The trash can main body 11 has an input port 14 that opens to the front side at the upper part. The input port 14 communicates with the garbage storage space 13 in the trash can main body 11. The garbage thrown into the input port 14 by the site user is stored in the garbage storage space 13.

The trash can main body 11 is placed on a mounting surface 16 such as a floor or the side of an aisle via legs 15 provided at each lower corner portion, and a trash storage space 13 is defined inside. The equipment arrangement space 17 is sandwiched between the partition wall 18 and the bottom wall 19 of the trash can main body 11 from the upper side and the lower side, respectively, and is formed on the lower side of the trash storage space 13.

Each removable capture box 12 can be inserted and removed from the insertion / removal opening 28 (FIG. 2) formed on the front surface of the trash can main body 11 into the equipment arrangement space 17. The handle 20 is fixed to the front surface of the trash can main body 11 and is gripped when the removable capture box 12 is inserted and removed.

(Outline of removable capture box)
FIG. 2 is an explanatory diagram of the insertion / removal of the removable capture box 12. On the front surface of the trash can main body 11, a plurality of (eg, three) insertion / removal openings 28 for inserting / removing the removable capture box 12 into the equipment arrangement space 17 are formed. The removable capture box 12 includes a rectangular parallelepiped casing 22 that is long in the front-rear direction of the trash can main body 11. The inner surface of the casing 22 is colored black in order to absorb infrared light Ri1 and Ri2, which will be described later, and suppress reflection.

The capture box entrance 25 has a size (dimension) that allows the mouse 40 (FIG. 4) to pass through. The shutter 21 is coupled to the upper end portion on the inner surface side of the casing 22 on the upper side so as to be swingable between the open position where the capture box inlet 25 is opened and the closed position where the capture box inlet 25 is closed.

When the removable capture box 12 is mounted in the equipment arrangement space 17, a predetermined rear space is left between the rear end of each casing 22 and the inner surface on the inner surface of the trash can main body 11. The mouse entrance 30 is formed on the bottom wall 19 of the trash can main body 11 so as to face the space behind it.

FIG. 3 is an explanatory diagram of a route through which the mouse 40 enters the capture space 23 of the removable capture box 12. Inside the casing 22, food 32 is set on the bottom surface of the front end portion in the capture space 23. The mouse 40 enters the equipment arrangement space 17 from the space between the mounting surface 16 and the bottom wall 19 of the trash can main body 11 through the mouse entrance 30. Next, the mouse 40 enters the capture space 23 through the capture box entrance 25 in the open state (in FIG. 3, the shutter 21 is shown in the closed position instead of the open position).

(Closed mechanism / solenoid type)
FIG. 4 is a perspective view of the removable capture box 12 in which the closing mechanism is an electric type. The actuator 50 is arranged adjacent to the rear end portion of the removable capture box 12 in the equipment arrangement space 17. The actuator 50 is a solenoid type actuator that has a built-in solenoid and moves the engaging pin 51 forward and backward by using the electromagnetic force generated by the energization of the solenoid. An insertion hole (not shown) is bored in the upper part of the side wall at the rear end of the removable capture box 12, and the engaging pin 51 swings the shutter 21 of the capture space 23 through the insertion hole. Advances and retreats with respect to the movement path.

The pressure sensor 57 is composed of a weight gauge and is laid on the bottom surface of the casing 22. In the pressure sensor 57, the wiring 58 transmits a detection signal as a pressure detection signal of the pressure sensor 57 to the actuator 50 (entrance determination device). Although not shown, the wiring 58 can be separated from the wiring on the removable capture box 12 side via a connector (not shown) so that the removable capture box 12 can be inserted and removed from the trash can main body 11. It is connected to the.

At the start of capture of the mouse 40, that is, when the removable capture box 12 is inserted and set in the equipment arrangement space 17, the shutter 21 swings and the shutter is in the open position where the capture box entrance 25 is opened. Holds 21. Specifically, the engaging pin 51 of the actuator 50 is in a protruding position that protrudes into the casing 22 through a predetermined insertion hole. As a result, the shutter 21 in the open position is prevented from swinging downward by the engaging pin 51 and is held in the open position.

When the mouse 40 enters the capture space 23 from the capture box inlet 25 and comes into contact with the pressure sensor 57, the pressure detection of the pressure sensor 57 changes depending on the weight of the mouse 40. The actuator 50 detects that the mouse 40 has entered the capture space 23 from the detection signal of the pressure sensor 57, and retracts the engagement pin 51 to the outside of the removable capture box 12. As a result, the shutter 21 swings according to its own weight or the urging force of a spring (not shown), and closes the capture box inlet 25. As a result, the mouse 40 is confined in the capture space 23 and captured.

(Opening prevention mechanism / Part 1)
The removable capture box 12 includes an opening prevention mechanism 60. When the management center or the like is notified that the mouse 40 has been captured in the removable capture box 12, the worker goes to the mouse capture device 10 and detaches the removable capture box 12 from the mouse capture device 10. To do.

As a work after capturing the mouse 40 in the removable capture box 12, it is necessary to kill the mouse 40 in the removable capture box 12. It is not suitable for the deployment site of the mouse capture device 10, and the worker needs to carry the removable capture box 12 detached from the mouse capture device 10 to an appropriate place.

However, if the shutter 21 is inadvertently opened during transportation, the mouse may escape from the capture box entrance 25. The opening prevention mechanism 60 prevents the shutter 21 from being inadvertently opened during such work.

The opening stop mechanism 60 includes a connecting rod 61, a knob 62, and a stop plate 63. The knob 62 is arranged on the front surface of the casing 22 so that an operator can grip the knob 62 from the outside of the casing 22 and rotate it. The stopper plate 63 is swingably attached to the peripheral edge of the rear wall of the casing 22 that defines the capture box inlet 25 inward. The connecting rod 61 extends in the front-rear direction of the casing 22 along the lower end of one side wall of the casing 22, and is connected to the knob 62 and the stopper plate 63 at both ends, respectively.

When the worker grips the knob 62 and rotates it, the rotational displacement is transmitted to the stop plate 63 via the connecting rod 61, and the stop plate 63 rotates. When the shutter 21 is in the closed position where the capture box entrance 25 is closed, the stopper plate 63 is set to the lock position in which the tip portion extends inward beyond the peripheral edge of the capture box entrance 25. As a result, the stop plate 63 suppresses the shutter 21 from the back surface (inner surface) toward the capture box inlet 25 as a stopper, and prevents the shutter 21 from moving away from the capture box inlet 25.

When the shutter 21 is in the open position, the stop plate 63 is in the unlocked position in which the tip end portion is retracted to the outside of the peripheral edge of the capture box entrance 25. As a result, the shutter 21 can swing from the open position to the closed position without interfering with the stop plate 63.

The worker may carry the removable capture box 12 in which the mouse 40 is captured from the installation location of the mouse capture device 10 to another location. At that time, in order to prevent the shutter 21 from being inadvertently opened, the worker rotates the knob 62 to lock the stop plate 63, and then starts moving.

The opening of the shutter 21 can be stopped by the worker even before the worker detaches the removable catch box 12 from the mouse catching device 10.

(Closing mechanism / mechanical / part 1)
FIG. 5 is a perspective view of the removable capture box 12 in which the closing mechanism 70 is a mechanical type. The closing mechanism 70 includes a tread plate 71, a stay 72, a wire 73, and an engaging member 74. The tread plate 71 is attached to the bottom surface inside the casing 22 at an intermediate portion in the front-rear direction of the removable capture box 12. The tread plate 71 has a seesaw structure in which both ends in the front-rear direction are swung around an intermediate fulcrum in the front-rear direction. The swing of the tread plate 71 is transmitted to the engaging member 74 via the stay 72 and the wire 73.

When the mouse 40 enters the capture space 23 from the open capture box entrance 25 and steps on the front end portion of the tread plate 71, the front end portion receives the weight of the mouse 40 and resists the urging force of the spring (not shown). And descend. The spring can be omitted. In that case, a weight having a predetermined weight is attached to the rear end side of the tread plate 71, or the length of the rear end side with respect to the fulcrum is increased with respect to the front end side.

The engaging member 74 swings in conjunction with swinging due to the lowering of the front end portion of the tread plate 71, and the engaging member 74 swings to a position retracted from the shutter 21 in the open position to release the engagement. To do. As a result, the shutter 21 swings from the open position to the closed position due to the weight on the free end side and / or the urging force of the spring (not shown), and closes the capture box inlet 25.

(Closing mechanism / mechanical / part 2)
FIG. 6 is a perspective view of a removable capture box 12 provided with another mechanical closing mechanism 80. FIG. 7 is a schematic view showing the removable capture box 12 of FIG. 6 from above. In the removable capture box 12, the capture box inlet 89 is formed not at the rear end of the casing 22 but at the rear end of the bottom wall of the casing 22. The position of the capture box entrance 89 is such that it overlaps with the capture box entrance 25 when the removable capture box 12 is mounted in the equipment arrangement space 17.

The closing mechanism 80 includes a tread plate 81, a wire 82, an engaging member 83, a torsion spring 84, and an engaging pin 85. The tread 81 has the same structure as the tread 71 (FIG. 5). The engaging member 83 is swingably coupled to the casing 22 around an axis in the lateral width direction of the casing 22 in a front view. The wire 82 connects the front end of the tread plate 81 and the front end of the engaging member 83. The torsion spring 84 is interposed between the rear end of the tread plate 81 and the front end of the shutter 88, and urges the shutter 88 rearward.

When the mouse 40 steps on the front end side of the tread plate 81, the front end side is lowered by the weight of the mouse 40. As a result, the wire 82 is pulled forward by the lowering of the front end side of the tread plate 81, and the rear end of the engaging member 83 is swung upward. As a result, the locking of the shutter 88 by the engaging member 83 is released, and the shutter 88 moves rearward by the urging force of the torsion spring 84, and switches from the open position to the closed position where the capture box entrance 89 is closed.

When the mouse 40 steps on the front end side of the tread 81, the long tail of the mouse 40 may be outside the capture box entrance 89. However, as the shutter 88 slides to the closed position, the tail of the mouse 40 gradually moves from the front end to the upper surface of the shutter 88, so that the tail is the trailing edge of the shutter 88 and the capture box entrance 89. It is prevented that the shutter 88 is not completely closed by being sandwiched between the two.

(Opening prevention mechanism / Part 2)
FIG. 8 is a configuration diagram of a curved spring 95 as an opening prevention mechanism. The connecting rod 61 (FIG. 4) automatically stops the shutter 21 from opening. The shutter 21 passes through the intermediate position Pq when switching from the open position to the closed position Pc.

The curved spring 95 is fixed at the base end 96 at a portion on the inner surface of the side wall of the casing 22 near the capture box inlet 25, and the free end side extends toward the rear capture box inlet 25.

The curved spring 95 has a convex portion 97 that projects inward in the lateral direction (horizontal direction) at the intermediate portion. The curved transition portion 98 is located between the base end 96 and the convex portion 97, and the amount of protrusion in the lateral direction is gradually increased as the portion moves from the base end 96 toward the convex portion 97. On the other hand, the confronting portion 99 bends at a substantially right angle from the convex portion 97 and confronts the capture box inlet 25 at the closed position Pc in parallel.

When it is detected that the mouse 40 has entered the capture space 23, the shutter 21 switches from the open position to the closed position Pc. At that time, the shutter 21 brings the side edge into contact with the curved transition portion 98 at the intermediate position Pq. The curved spring 95 has elasticity in the lateral direction, and the curved transition portion 98 gently changes the amount of protrusion in the lateral direction. As a result, the shutter 21 gets over the convex portion 97 while pushing the curved transition portion 98 laterally outward, and becomes the closed position Pc.

When the shutter 21 tries to swing from the closed position Pc toward the intermediate position Pq, the facing portion 99 acts as a stopper and holds the shutter 21 at the closed position Pc.

Since the opening prevention force of the curved spring 95 is weak, it can be easily released by strongly pressing the shutter 21 from the outer surface side thereof with a finger.

(Rat detector)
FIG. 9 is a configuration diagram of the mouse detection unit 100. The mouse detection unit 100 includes one control device 101 and a plurality of actuators 50, and is arranged in the equipment arrangement space 17 together with the removable capture box 12. The control device 101 includes a power supply unit 102 and a control unit 103. The power supply unit 102 is typically connected to a commercial power outlet in the premises where the mouse capture device 10 is installed via an external wiring such as a power cord or the like. It is also possible to use batteries instead of commercial power.

Each actuator 50 includes a light source 107 that emits infrared light Ri1 in addition to the engagement pin 51 described above in FIG. Each actuator 50 is connected to the control device 101 via wiring 110. The wiring 110 is a harness for a signal line, a control line, and a feeding line.

FIG. 10 is an explanatory diagram of detection of the mouse 40 by infrared light Ri1. The window 113 has a size that the mouse 40 cannot pass through, and is formed on the side wall of the casing 22. The window 113 may be a mere through hole, or may be fitted with glass or the like capable of transmitting infrared light Ri1.

The inner surface of the casing 22 is black, which absorbs infrared light Ri1, except for a part of the inner surface of the shutter 21. In addition to the light source 107, the actuator 50 receives an infrared light Rr1 (unsigned) emitted from the capture space 23 to the outside of the removable capture box 12 through the window 113 (example: PD (example: PD). Photo Detector)) is provided.

The control unit 103 includes an approach determination unit that detects the presence or absence of the mouse 40 in the capture space 23 based on the amount of infrared light received by the light receiving element of each actuator 50. When the mouse 40 is in the capture space 23, the mouse 40 reflects the infrared light Ri1. As a result, the amount of infrared light Ri1 (not shown) emitted from the window 113 to the outside by the reflection of the mouse 40 with respect to the infrared light Ri1 emitted from the window 113 into the capture space 23 increases. Therefore, the presence or absence of the mouse 40 in the capture space 23 can be detected from the amount of infrared light received by the light receiving element arranged outside the window 113.

(Closed detector)
FIG. 11 is a configuration diagram of the closure detection unit 120. In the closure detection unit 120, a window 121 is provided on the side wall portion of the casing 22 near the capture box entrance 25. In FIG. 11, the window 121 is formed on the right side wall of the casing 22 when viewed from the front of the trash can main body 11, but it can also be formed on the left side wall as in the window 113 (FIG. 10). In that case, the position of the window 121 is lower than the position of the window 113. For the detection of the mouse 400, it is advantageous to irradiate the infrared light Ri1 from a high portion of the casing 22, whereas for the detection of the closed position of the shutter 21, it is advantageous to detect the lower end of the shutter 21. Is.

Although not shown in FIG. 11, in order to irradiate the infrared light Ri2 from the terminal side wireless communication unit 211, a light source of the infrared light Ri2 and an infrared light source outside the window 121 are provided separately from the light source 107. A light receiving element that receives the infrared light Ri2 of the light Ri2 is arranged.

In order to detect whether or not the shutter 21 is in the closed position, the portion of the inner surface of the shutter 21 that is irradiated with the infrared light Ri2 is not black but white that easily reflects the infrared light Ri2. Is desirable. This is because the amount of infrared light Ri2 increases.

Whether or not the shutter 21 is in the closed position based on the amount of reflected light of the infrared light Ri2 emitted from the capture space 23 through the window 121 by the light receiving element arranged outside the window 121. Can be detected.

The reason why the closure detection unit 120 is equipped separately from the mouse detection unit 100 is that the shutter 21 is in the closed position even though the mouse 40 is not in the capture space 23 due to the malfunction of the closing mechanism and the skillful escape of the mouse 40. Because it can happen. In such a case, since it is difficult to capture the mouse 40, the worker immediately goes to the site and performs work such as returning the shutter 21 to the open position.

Further, the lighting of the light source 107 for emitting the infrared light Ri1 of the mouse detection unit 100 and the lighting of the light source for emitting the infrared light Ri2 of the closed detection unit 120 are not performed at the same time, but are performed at different times. .. This is to prevent the light receiving elements of the mouse detection unit 100 and the closure detection unit 120 from detecting the reflected light from the uncorresponding light source and causing erroneous detection.

(Rat capture system)
FIG. 12 is a block diagram of the mouse capture system 200. The monitoring site 201 is a site where a single or a plurality of mouse catching devices 10 such as a railway station are installed. A single gateway 202 is deployed for each monitoring site 201. The gateway 202 of each monitoring site 201 and the server 205 send and receive data via the Internet 208.

FIG. 13 is a block diagram of the hardware configuration of the gateway 202. The gateway 202 includes a control unit 210, a terminal-side wireless communication unit 211, a net-side wireless communication unit 212, a memory 213, and a clock 214 connected to the control unit 210.

The terminal-side wireless communication unit 211 wirelessly transmits and receives data to and from a single or a plurality of mouse capture devices 10 deployed at the same monitoring site 201 as the terminal-side wireless communication unit 211. For this communication method, for example, communication by Sub-GHz radio is used.

The net-side wireless communication unit 212 is connected to the Internet 208 and transmits / receives data to / from the server 205 via the Internet 208.

The control unit 103 of each mouse capture device 10 operates the mouse detection unit 100 and the closure detection unit 120 at a regular time every day or at regular time intervals to determine the presence or absence of the mouse 40 in the casing 22 and the shutter 21. It is designed to detect whether or not it is in the closed position. Then, the detection information is sent to the gateway 202 together with the information of the identifier ID of the control unit 103, and the gateway 202 stores the information in the memory 213 in association with the information of the reception time.

FIG. 14 is a block diagram of the hardware configuration of the server 205. The server 205 includes a control unit 220 and a database 221 and a display 222 that can send and receive data between the control unit 220.

The control unit 220 further includes a polling unit 225, a presence / absence determination unit 226, a closure determination unit 227, and a determination result output unit 228.

FIG. 15 is a flowchart of the monitoring process executed by the control unit 103 (FIG. 9) equipped in the mouse capture device 10. The control unit 103 has a built-in timer or clock. In this flowchart, a timer is used to detect the polling timing.

In S231, the control unit 103 determines whether or not the set time has elapsed based on the output of the timer. The set time of the timer determines the collection interval of the presence / absence information of the mouse and the closing information of the shutter 21 in the mouse catching device 10. In addition, the capture information shall include at least existence / non-existence information and closure information.

When the determination in S231 is positive, the control unit 103 advances the process to S232, and when the determination in S231 is negative, the control unit 103 ends the process.

In S232, the control unit 103 turns on the infrared light source. This infrared light source includes not only the light source 107 that emits the infrared light Ri1 of FIG. 10 but also a light source (not shown) that emits the infrared light Ri2 of FIG. Lighting of multiple infrared light sources is not simultaneous, but staggered. This is because the light receiving elements of the mouse detection unit 100 and the closure detection unit 120 accurately detect the amount of reflected light received with respect to the infrared light emitted by the corresponding infrared light source.

In S233, the control unit 103 detects the light receiving amounts Rn1 and Rn2 of the light receiving element. The light receiving amounts Rn1 and Rn2 correspond to the light receiving amounts of the reflected light with respect to the infrared lights Ri1 and Ri2, respectively. That is, the light receiving amount Rn1 is used in the process of determining the presence or absence of the mouse 40 in the capture space 23, and the light receiving amount Rn2 is used in the process of determining the closed position of the shutter 21. These constitute the mouse 40 capture information (⊃ existence / non-existence information + closure information) for the mouse capture device 10.

In addition, the control unit 103 can also transmit the detection times of the received light amounts Rn and Rn2 to the gateway 202. Note that the gateway 202 can use each reception time as the detection time without receiving information about the detection time from the control unit 103.

The gateway 202 receives the capture information and the closure information from all of the mouse capture devices 10 under its jurisdiction, and stores the capture information and the closure information in the memory 213 until polling from the server 205.

In S234, the control unit 103 wirelessly transmits information regarding the identifier ID and the received light amounts Rn1 and Rn2 to the gateway 202. As described above, Sub-GHz radio is used for this radio communication.

The identifier ID is information that not only identifies the monitoring site 201 but also identifies the location of the monitoring site 201 that is the mouse capture device 10. In the database 221 (server 205) described later, the identifier ID of the mouse capture device 10 and the location of the control device 101 associated with the identifier ID (= the installation location of the mouse capture device 10) are stored in association with each other. Has been done.

FIG. 16 is a flowchart of processing executed by the control unit 220 (FIG. 14) of the server 205.

In S241, the polling unit 225 determines whether or not the current time is the polling time. The polling time is set to one or more fixed times every day, or is assigned a fixed time interval. The polling time can be assigned to each monitoring site 201.

In S242, the polling unit 225 polls the gateway 202.

In S243, the polling unit 225 collects capture information from the polling unit 225 corresponding to the polling of S242. Specifically, the capture information includes the identifier ID of each mouse capture device 10 described in S234 described above and the received light amounts Rn1 and Rn2. The capture information includes information on the presence / absence of the mouse 40 in the capture space 23 of each mouse capture device 10 and information on the closing position of the shutter 21.

In S244, the capture information is determined. The presence / absence determination unit 226 determines the presence / absence of the mouse 40 from the presence / absence information of the captured information. The closing determination unit 227 determines the closing position information.
