[Figure 11] Figure 3 is a perspective view showing the sixth embodiment of the bait detection device (an example of a structure that attracts the point of action). [Modes for carrying out the invention]
[0009] Embodiments of the present invention will be described below with reference to the drawings. First, we will explain the background leading up to the conception of the embodiments of the present invention. Buildings and other structures must be maintained in accordance with the local ordinances and guidelines of the area in which they are constructed. For example, in one local city, it is mandated that inspections for the presence of rodents and other pests be conducted at least once a month. Therefore, building managers must inspect the presence of pests at least once a month. Specifically, an administrator who manages a building or a worker entrusted by the administrator climbs onto the ceiling using a stepladder, sets a trap for detecting pests (mainly rats), and regularly checks its status to check for the presence of pests. A special "bait" is used for the trap, which is non-toxic bait for attracting rather than killing, or sunflower seeds, etc. Since the inspection work is high-altitude work, for example, it is necessary to act in a two-person system (a system of multiple people) consisting of a high-altitude worker and an assistant who supports the worker. The means for detecting the presence of rats is for the worker to visually check whether the bait for attraction has been eaten. Since the target areas are places where rats are likely to wander, such as the ceiling space, narrow places, and places with a lot of moisture, it takes time for the worker to visually check. Since human work is required for the inspection work, the number of people available becomes a bottleneck and new customers cannot be acquired. Under the above background, the present invention was conceived.
[0010] Hereinafter, a bait consumption detection service using a bait consumption detection device according to an embodiment of the device of the present invention will be described with reference to FIG. 1. FIG. 1 is a diagram showing a bait consumption detection service (hereinafter referred to as "this service") using a bait consumption detection device according to an embodiment of the device of the present invention.
[0011] As shown in FIG. 1, in this service, when a pest (small animal) such as a rat N eats the bait E attached to one end of the arm of the bait consumption detection device 1 (device) arranged on the ceiling of a building or the like, and a predetermined condition that one end becomes lighter is satisfied, the bait consumption detection device 1 detects the bait consumption, and the fact of the detection or the detected information is transmitted from the wireless communication unit (transmission unit) to a worker (inspection worker) in the building room, thereby informing the inspection worker of the presence of the pest (small animal). Transmitting the fact of the detection includes, in addition to transmitting radio waves, for example, lighting an LED or sounding a buzzer. The bait E may be directly attached to one end of the arm, or may be placed in a container such as a tray arranged at one end of the arm. The tray is a container that houses the bait E that can be eaten by small animals such as the rat N.
[0012] The bait E is made from something that mice N like to eat (for example, a solid made by hardening a powder mainly composed of sunflower seeds and processing it into a rectangular prism shape). A through-hole is provided in the center of the bait E, and the support part 43 (see Figure 4, etc.), described later, is inserted into the through-hole to attach the bait E to the device. When using a container such as a tray, sunflower seeds as they are may be used as the bait E. Alternatively, bait E mixed with poison, so-called poisoned bait, may be used.
[0013] Furthermore, the bait E may be provided by the service provider as a single unit formed from multiple pieces, and the bait may be used by breaking it apart along the cut lines. Bait E may also be other materials or mechanisms, as long as the weight of the part touched by the mouse N changes (becomes lighter or heavier).
[0014] The bait detection device 1 has the function of transmitting a predetermined signal, such as a Bluetooth signal, as a beacon at regular intervals. Note that Bluetooth is a registered trademark. The power source for this device is dry cell batteries, and with two dry cell batteries connected in parallel, it can operate for approximately six months (about half a year). For the dry cell batteries, considering the miniaturization of the device, operating life, and power consumption, it is preferable to use batteries such as "AA" or "AAA". This invention is not limited to the type or capacity of the batteries. The battery capacity shall be determined according to the radio wave strength, transmission frequency, and battery replacement frequency.
[0015] Field terminal 2 has an application program (hereinafter referred to as "the app") provided by the service provider installed. When the app is launched, field terminal 2 receives a predetermined signal transmitted from the bait detection device 1 and displays the presence or absence of the signal on the app's screen. The predetermined signal is, for example, a beacon, which is one of the radio waves transmitted periodically from the bait detection device 1. In this way, when receiving beacons, a person carrying the field terminal 2 with the app running can receive them simply by passing near the location where the bait detection device 1 is installed (for example, on a floor). Therefore, data can be easily collected by people such as cleaning staff or floor representatives, rather than through patrols for inspection or survey purposes. Other basic functions of the app include checking the status of the food, checking the battery level, and confirming the installation location. Other app features include reporting, notifications for when to replace batteries and food, and a function to manage detection locations.
[0016] This service eliminates the need to visually check the condition of bait E, as it can be checked remotely using a PC, smartphone, etc., which is expected to improve work efficiency. Furthermore, work in confined spaces and at heights will only be required when necessary (installation, bait replacement, etc.). For pest detection, the existing method of checking using bait E will be applied, improving work efficiency without changing the accuracy of the checks. Since checks can be performed early after detection, it will be possible to deal with highly reproductive pests such as rats before their numbers increase.
[0017] In addition, this service can also provide the following benefits: For example, with a simple structure like "contact is lost," it's possible to check the status requiring on-site response—such as "detection, malfunction, and battery depletion"—in a single action. By simplifying the unique bait-feeding sensor and communication functions, power savings can be achieved. Because it does not require Wi-Fi or other communication equipment, nor does it use a power source, it can be used in a variety of locations. Since it can operate for extended periods on dry cell batteries, the same level of work can be performed with minimal patrols. This will improve operational efficiency because patrols will only need to be conducted when an anomaly notification is received. Since there will be no work at heights, regular inspections can be easily done by one person. By reducing the manpower required for patrol work, we can expand our customer base. The system also tracks the occurrence of rats (pests) in neighboring areas and maps them, allowing for an understanding of their habitat and movement patterns. By developing a shape and tray for the food bait E that attaches to one end of the arm, changing the bait will become even easier. We can recommend the most suitable pest control company based on the area where the infestation occurred. Because bait consumption can be detected in real time, it's possible to take action before the rat population increases.
[0018] In the above embodiment, the building to be inspected was described as a building and the small animal as a mouse. However, the inspection target could also be an empty house, and pests such as civets and raccoons could be detected. This technology can be applied to detecting wandering elderly people, IoT-based management of kerosene levels used in facility gardening, and more.
[0019] Next, referring to Figure 2, we will explain the service provided by the signal processing system including the bait-feeding detection device shown in Figure 1. Figure 2 shows the service provided by the signal processing system, including the bait-feeding detection device shown in Figure 1.
[0020] As shown in Figure 2, the signal processing system of the embodiment comprises a bait detection device 1 installed on the ceiling of a building, a field terminal 2 that communicates wirelessly with the bait detection device 1 via Bluetooth, and a monitoring terminal T that is connected to the field terminal 2 via a network NW such as a cloud.
[0021] The monitoring terminal T is a device managed and operated by the monitor O, and can be, for example, a smartphone, tablet, or personal computer.
[0022] The field terminal 2 is a smartphone, tablet, or personal computer with the app installed, and has a monitoring function K that monitors the Bluetooth signal transmitted from the bait detection device 1. The monitoring function K of the field terminal 2, upon detecting an interruption in the reception of the Bluetooth signal transmitted from the bait detection device 1, outputs information indicating the detection result as signal loss information via the network NW to the monitoring terminal T of the monitor O or the website W managed by the service provider. In other words, it detects mice that come to eat bait E, collects the detection result using the app on the field terminal 2, and transmits the collected data via the network NW to the monitoring terminal T or website W (cloud server, etc.). This allows the monitor O, who is monitoring the monitoring terminal T or the website W, to reliably recognize when the battery of the bait detection device 1 runs out or when there is a pest (small animal) such as a mouse N.
[0023] The following describes the definition of a user and the functions of the web application (hereinafter referred to as "the application") implemented on the field terminal 2 or on a cloud server, etc. Users are categorized into system administrators, on-site administrators, and on-site users. System administrators are service providers, while on-site managers include managers of building maintenance companies or inspection companies, store owners, etc. On-site users include on-site workers from the inspection company, store owners, and employees.
[0024] The user-specific features of the app provided by the service provider are as follows: System administrators are provided with functions necessary for management tasks, such as the ability to check system operation logs, register users, view all user data, and change status. Site managers are provided with functions to facilitate on-site work, such as user registration, site management functions, and shift management functions, as well as functions that enable them to comprehensively handle administrative tasks related to inspection work. Additionally, features for checking the status of the device, such as alert confirmation, will be provided. On-site users are provided with support functions to enable efficient work, such as the ability to view survey buildings, manage work tasks, and confirm customer inspection routes. The work task management function is designed to prevent omissions in survey work. In addition, on-site users are provided with functions such as the ability to create inspection and survey reports.
[0025] Common features of the app provided by the service provider include beacon reception, mapping, and pest outbreak information sharing. The beacon reception function receives beacon signals from the bait detection device 1. The mapping function allows users to view mapping information. The pest outbreak information sharing function shares information about pest outbreaks with each user when bait consumption is detected.
[0026] This service can produce the following effects: 1. Allows one person to perform work at heights (ceiling-mounted type). 1-1. In the case of ceiling-mounted units, the inner case can be removed to the interior using a key jig attached to the end of a rod. This allows for feeding and battery replacement to be done by one person, eliminating the need for working at heights. 1-2. It eliminates the need for ladders and equipment, reducing travel time and improving work efficiency. 2. Foraging conditions can be confirmed without relying on visual inspection. 2-1. The condition of the feed is monitored using a proprietary sensor, and the condition can be checked via a smartphone application. 2-2. Monitoring can be conducted 24 hours a day, 365 days a year, allowing for the detection of highly reproductive pests such as rats before they multiply (response can be taken as soon as they consume the bait). 3. The status of the installation location can be monitored remotely. 3-1. By managing information received by local applications in the cloud, remote installation locations can be easily verified. 3-2. The status of the feed and battery can also be checked in the cloud. 4. Tasks for each survey terminal can be easily checked. 4-1. You will be notified when it's time to change the feed or the battery. 4-2. You will be reminded of the timing of your scheduled patrols. 5.

The situation regarding the occurrence of pests can be confirmed. 7-1. Detection status is displayed on the map, allowing you to check the situation in the vicinity. 7-2. You can check information about pests and related information. 7-3. AI can predict future damage.
[0027] Next, with reference to Figures 3 to 6, a first embodiment of the bait-eating detection device included in the signal processing system described above will be explained. Figure 4 is a cross-sectional view showing the state of the condition detection unit of the feeding detection device shown in Figure 3 when the support unit is in the first position. Figure 5 is a cross-sectional view showing the state of the condition detection unit of the feeding detection device shown in Figure 2 when the support unit has moved to height position B. Figure 6 is a perspective view showing an example (first embodiment) where the detection unit of the condition detection unit in Figure 5 is a photosensor.
[0028] First, the circuit configuration of the bait-eating detection device of the first embodiment will be explained with reference to Figure 3. Figure 3 shows the circuit configuration of the bait-eating detection device included in the signal processing system shown in Figure 2. The bait detection device included in the signal processing system shown in Figure 2 has the circuit configuration shown in Figure 3. Specifically, as shown in Figure 3, the feeding detection device 1 has a condition detection unit 4 and a control unit 10.
[0029] The control unit 10 includes a control board 11, an LED L or beacon board 12, a dry cell battery 13, and the like. The beacon board 12 is controlled by the control board 11 and transmits a beacon. The beacon board 12 has a circuit that uses power supplied from a dry cell battery 13 (a predetermined power source) to transmit, for example, a beacon (a predetermined signal). The beacon board 12, as a beacon, transmits a Bluetooth signal within a radius of 10 meters (with a predetermined range) from, for example, a transmission point (set location). The Bluetooth signal is transmitted at predetermined timings. The predetermined timing is a fixed interval (for example, every n seconds).
[0030] By installing the app on the field terminal 2 carried by the worker, the field terminal 2 can receive the beacon on the floor, etc., so simply by installing the app on the field terminal 2, a low-cost function for monitoring bait consumption by pests can be implemented.
[0031] The dry cell battery 13 is a designated power source that supplies power to the control board 11 and the beacon board 12. This allows the device to be installed in places without wiring, such as ceilings. It also makes it easy to move the installation location. Two dry cell batteries 13, for example, can power the device for approximately six months.
[0032] The control unit 11 switches the circuit's conduction state from ON to OFF when predetermined conditions are met, based on the circuit's conduction state being ON. The predetermined conditions are when the power supply from the dry cell battery 13 is interrupted and when bait consumption is detected. The control board 11 controls the beacon board 12 to transmit a beacon using power supplied from the dry cell battery 13. The control board 11 also controls the LED L to light up using power supplied from the dry cell battery 13. The control board 11 monitors the voltage of the dry cell battery 13, and when the voltage of the dry cell battery 13 falls below a predetermined amount (e.g., 60%) within the voltage range in which the control board 11 can operate, it transmits additional power drop information via a beacon. However, when the voltage of the dry cell battery 13 falls below a voltage value in which the control board 11 will not operate (e.g., 0.6V or less) (in the case of battery failure), the beacon transmission stops.
[0033] As shown in Figure 4, the above-mentioned condition detection unit 4 comprises a seesaw structure including a rotating shaft 41 and an arm 42, and a detection unit 50.
[0034] The seesaw structure comprises a pivot point 41 (fulcrum) positioned offset from the center of gravity of the arm 42, a support part 43 (point of force application) positioned at one end of the arm 42, and a spring mounting part 44 (point of application) positioned at the other end of the arm 42.
[0035] A coil spring 45 is mounted on the spring mounting section 44 with its lower end fixed. The upper end of the coil spring 45 abuts against a member 38 fixed to the housing of the device, and the coil spring 45 generates a pressing force so that the arm 42 maintains a parallel position when the bait E is attached, as shown in Figure 4. The spring mounting section 44 is subjected to the weight (spring load) of the coil spring 45, and the pressing force (detected load) of the coil spring 45 is set by the force obtained by subtracting this spring load. These members constitute the biasing mechanism.
[0036] The detection unit 50 includes, for example, a photosensor 51 fixed to the housing of the device, a light-shielding member 52 fixed to the point of application side of the arm 42, and a biasing mechanism attached to the point of force application side of the arm 42 to offset the weight of the bait E and the arm 42. The biasing mechanism may be the coil spring 45 or the like.
[0037] Here, we will explain how to calculate the detected load at the point of application. The detected load at the point of application can be calculated using the distance between the fulcrum and the point of force application (and the point of application) and the compressive force of the coil spring 45. Let the downward force F1 [N] be the sum of the load of bait E and the weight of arm 42, the upward force at the spring mounting part 44 (point of application) be the detected load F2 [N], the compressive force of the coil spring 45 be the spring load F3 [N], the distance from the axis of rotation 41 to the point of application of force on arm 42 be distance L1, and the distance from the axis of rotation 41 to the point of application on arm 42 be distance L2. Then F2 = {(L1 / L2) × F1} - F3 [N]. The above calculation formula is an example of the ON state with bait E attached, as shown in Figure 4. On the other hand, in the case of the ON state when there is no bait E as shown in Figure 5, if the downward force of the arm 42's own weight is defined as load F1 [N], the upward force of the reaction force of the spring load is defined as load F2 [N], and the downward force of the spring mounting part 44 (point of application) is defined as the detected load F3 [N], then F3 = F2 - {(L1 / L2) × F1} [N].
[0038] In this example, a coil spring 45 is used as an example of a biasing mechanism that can continuously apply a pressing force, but other biasing mechanisms or elastic bodies may also be used, as long as they are elastic and can apply a pressing force. Depending on the position of the point of application to which the biasing mechanism is attached, a tensile force may be used instead of a pressing force (see Figure 11).
[0039] In this seesaw structure, by attaching the bait E to the support part 43, the weight of the bait E and the pressing force (pressing force) of the coil spring 45 are balanced, and the support part 43 is held at height position A.
[0040] As shown in Figure 4, the condition detection unit 4 includes the rotation axis 41 (fulcrum) of the arm 42, a support part 43 provided at one end of the arm 42 which functions as a point of force application, a movement detection unit 40 that detects movement related to the movement of the other end (point of application) of the arm 42, and a detection unit 50 that detects when the bait E falls from the support part 43 as a condition that has been met.
[0041] Furthermore, the detection unit 50 detects that the predetermined conditions are met not only when the bait E falls, but also when, for example, a portion of the bait E is shaved off and the load becomes lighter than the threshold. In addition, the detection unit 50 also detects that the predetermined conditions are met when the mouse gnaws and destroys the arm 42 beyond the rotation axis 41 (a state in which the load F1 cannot be detected).
[0042] Specifically, in the first embodiment, the detection unit 50 employs a photosensor 51, as shown in Figure 6. The photosensor 51 includes a light-emitting unit that emits light to one of two opposing wall surfaces and a light-receiving unit that receives the said light to the other wall surface. The photosensor 51 detects when the light between the light-emitting unit and the light-receiving unit is blocked. In this example, the photosensor 51 detects that when the support unit 43 (one end of the arm 42) moves to height position B in Figure 5, the member 52 at the other end of the arm 42 lowers, and the member 52 blocks the light between the light-emitting unit and the light-receiving unit.
[0043] The movement detection unit 40 detects that, in order to maintain the ON state of the control board 11, a weight exceeding a threshold is continuously applied to the support part 43 of the bait E, which is the point of force application with respect to the rotation axis 41 (fulcrum) of the arm 42, and that when the weight applied to the height part A (the weight of the support part 43 and the bait E) falls below the threshold (the weight that disrupts the left-right balance around the fulcrum of the arm 42), the bait E has fallen off the support part 43 (see Figure 5) (a predetermined condition has been met).
[0044] The detection unit 50 detects that the weight of the support part 43 applied to height position A and the weight of the bait E have become lighter (weaker) than the biasing force of the coil spring 45 at the point of application of the seesaw structure (arm 42 and rotation axis 41) (the force pushing down on the other end (point of application) of the arm 42), causing the member 52 located at the other end of the arm 42 to lower and block the light from the photosensor 51, and notifies the control unit 10.
[0045] Here, a photosensor 51 is shown as an example of the detection unit 50, but the detection unit 50 may be other than this, and other examples of a seesaw structure including the arm 42 and a detection mechanism for detecting changes in the weight of the bait E will be described later.
[0046] The housing of the bait-feeding detection device 1 contains a circuit board including the control unit 10 and a battery. The housing has a hole on either the side or the top surface, and an LED L is fixed to this hole. The LED L is controlled by the control unit 10 and emits light outwards when the device is operating normally.
[0047] In this bait detection device 1, if the weight of the bait E attached to one end of the arm 42 exceeds a certain weight, the control unit 10 is activated by power supplied from the dry cell battery 13, causing it to emit a beacon signal or light up the LED L.
[0048] Here, the operation of the bait-feeding detection device of the first embodiment will be explained with reference to Figures 4 to 6. Figure 4 is a cross-sectional view showing the state of the movement detection unit of the feeding detection device shown in Figure 3 when the support unit is at height position A. Figure 5 is a cross-sectional view showing the state of the movement detection unit of the feeding detection device shown in Figure 2 when the support unit has moved to height position B. Figure 6 is a perspective view showing an example (first embodiment) where the detection unit of the motion detection unit in Figure 5 is a photosensor. As shown in Figures 4 and 6, with the bait E attached, the arm 42 is held at height position A, and as long as the light between the light-emitting and light-receiving parts of the photosensor 51 is not blocked by member 52, the control unit 10 turns the circuit ON (conductive state), power is supplied from the control unit 10, and the beacon continues to be transmitted.
[0049] Subsequently, when the bait E is eaten by a mouse N or the like, and the bait E falls off the support part 43 or is gnawed on and its load (weight) decreases, as shown in Figures 5 and 6, the rotation axis 41 of the arm 42 rotates in the direction of arrow R, and the position of the support part 43 moves from height position A to height position B (arrow Q). Consequently, the member 52 on the side of the arm 42 that is at the point of application lowers, blocking the light from the photosensor 51, and the photosensor 51 outputs a signal indicating that the light is blocked.
[0050] Upon receiving a signal from the photosensor 51 indicating light blocking, the control unit 10 switches the circuit's power supply state to the OFF state (non-conductive state). This cuts off the power supply to the beacon board 12 and LED L, stopping the beacon's transmission. LED L also turns off.
[0051] On-site terminal 2, when it receives or stops receiving beacons transmitted at regular intervals from bait detection device 1, the operating status of bait detection device 1 is displayed in real time on the app screen of on-site terminal 2.
[0052] The operating status of the bait detection device 1 is indicated by a list of bait detection devices 1 that are transmitting beacons (device identification numbers, etc.). When the beacon is no longer received, the device identification number of the bait detection device 1 in that list will be grayed out or activated, indicating that a malfunction such as a dead battery in the dry cell battery 13 has occurred, or that the device has entered a bait-eating state.
[0053] Since inspection is necessary when either the battery runs out or the animal eats the food, it is useful to keep the device with the LED lit or the beacon emitting at all times, and to turn off the LED or stop the beacon from emitting when an abnormality or food consumption occurs.
[0054] Thus, according to the bait-eating detection device 1 of the first embodiment, due to the seesaw structure, when the bait E attached to one end of the arm 42 is eaten or falls, that end rises, and the other end (point of application) of the arm 42 inside the device lowers due to the lever principle. By providing a detection unit 50 on the side of the point of application that detects the movement of the arm 42, bait eating can be detected. In other words, by utilizing the change in the weight of the food E when the mouse N eats it, the movement of the point of action inside the device can be used to detect when the mouse N is eating the food. By detecting a change in weight (decrease in load) of the arm 42 to which the bait E is attached that exceeds a threshold, the accuracy of detecting bait consumption can be improved compared to a device that detects, for example, when a mouse N pulls on the bait E. Furthermore, the detection unit that detects changes in the weight of the bait E and the movement of the arm 42 can utilize, for example, a custom-made contact structure or commercially available sensors and switches (for example, a photosensor 51 (see Figure 6), a magnetic sensor 53 (see Figure 7) described later, a metal terminal contact structure (see Figure 8), a microswitch 58 (see Figure 9), a touch switch, etc.), thus providing a wide range of options for the detection structure, taking into account cost, environment, and other factors. By receiving a beacon from the bait detection device 1 installed in the attic at the field terminal 2, workers can check bait consumption, battery depletion, etc. from the field terminal 2. This allows for pest animal surveys in attics, which previously required working at heights using ladders or stepladders, to be carried out with light equipment without the need for ladders or stepladders.
[0055] Next, other embodiments of the bait-feeding detection device will be described with reference to Figures 7 to 11. Note that the embodiments described below only show partial configurations (elements of the condition detection unit 4) in the figures, but they are part of the configurations described in Figures 1 to 3. First, a second embodiment (an example using a magnetic sensor) will be described with reference to Figure 7. Figure 7 is a perspective view showing a second embodiment of the bait-feeding detection device of Figure 3 (an example using a magnetic sensor). Note that the embodiments described below only show a partial configuration (elements of the condition detection unit 4) in the figures, but they are part of the configuration described in Figures 1 to 3. As shown in Figure 7, in the second embodiment, the detection unit 50 of the movement detection unit 40 includes a magnetic sensor 53 fixed to the base plate 39 of the main body of the device, and a magnet 54 positioned at the bottom (point of application) of the spring mounting portion 44 of the arm 42, corresponding to the position of the magnetic sensor 53.
[0056] In this second embodiment, as in the first embodiment, when the bait E is eaten by the mouse N and the load of the bait E decreases (the weight decreases), the support portion 43 at one end of the arm 42 lifts up around the pivot point, and the magnet 54 located at the opposite end (the point of application) of the arm 42 lowers. As a result, the magnet 54 approaches the magnetic sensor 53, and the contacts inside the magnetic sensor 53 are turned ON by the magnetism of the magnet 54, thereby detecting that the bait has been eaten.
[0057] Furthermore, when using a magnetic sensor 53 in the detection unit 50 of the movement detection unit 40, the magnetic sensor 53 will not react to the magnet 54 placed at the point of action of the arm 42 during normal operation (for example, when the arm 42 is nearly parallel to the bait), but will react (detect) when the arm 42 rotates in the direction of arrow S due to eating the bait, and the magnet 54 descends to a predetermined position and approaches the magnetic sensor 53. The specifications and distance between the magnet 54 and the magnetic sensor 53 must be considered accordingly.
[0058] Thus, according to this second embodiment, the detection unit 50 is composed of a magnetic sensor 53 and a magnet 54, and as the magnet 54 approaches the magnetic sensor 53 due to the rotation of the arm 42, it is possible to detect bait eating and satisfy the conditions for bait eating without contacting the object to be detected. As a result, the circuit's conductivity is switched from the ON state to the OFF state in the control unit 10, stopping the beacon transmission, and enabling reliable detection of the mouse N at the field terminal 2.
[0059] Next, a third embodiment (an example of a contact switch between metal terminals) will be described with reference to Figure 8. Figure 8 is a perspective view showing a third embodiment of the bait-feeding detection device shown in Figure 3 (an example using a contact switch between metal terminals). As shown in Figure 8, in the third embodiment, the detection unit 50 of the movement detection unit 40 includes a first metal terminal 55 fixed to the base plate 39 of the main body of the device, a projection 56 positioned on the spring mounting portion 44 of the arm 42 corresponding to the position of the first metal terminal 55, and a second metal terminal 57 positioned downward from the bottom of the projection 56.
[0060] In this third embodiment, as in the first embodiment, when the bait E is eaten by the mouse N and the load of the bait E decreases (the weight decreases), the support portion 43 at one end of the arm 42 lifts up around the pivot point, and the opposite end (the point of application) of the arm 42 lowers, causing the second metal terminal 57 to contact and engage with the first metal terminal 55, turning the contact ON and detecting that the bait has been eaten.
[0061] Furthermore, if the detection unit 50 of the movement detection unit 40 is to be a switch structure using contact between metal terminals, it is necessary to carefully consider the pressure when the first metal terminal 55 and the second metal terminal 57 are in contact, the force applied when they are fitted together (balance between contact pressure and weight), and the load setting. However, since no off-the-shelf products are used, the detection unit 50 can be constructed at low cost.
[0062] Thus, according to this third embodiment, the detection unit 50 is composed of the first metal terminal 55, the second metal terminal 57, and the projection 56, and the feeding of bait can be detected by a physical connection, such as when the second metal terminal 57 contacts and fits with the first metal terminal 55 due to the rotation of the arm 42, thereby satisfying the conditions for feeding. As a result, the circuit's conductivity is switched from the ON state to the OFF state in the control unit 10, stopping the beacon transmission, and enabling reliable detection of the mouse N at the field terminal 2.
[0063] Next, a fourth embodiment (an example using a microswitch) will be described with reference to Figure 9. Figure 9 is a perspective view showing a fourth embodiment of the bait-feeding detection device shown in Figure 3 (an example using a microswitch). As shown in Figure 9, in the fourth embodiment, the detection unit 50 of the movement detection unit 40 includes a microswitch 58 fixed to the circuit board 39 of the main body of the device, and a projection 56 positioned on the spring mounting portion 44 of the arm 42, corresponding to the position of the lever 59 of the microswitch 58.
[0064] In this fourth embodiment, as in the first embodiment, when the bait E is eaten by the mouse N and the load of the bait E decreases (the weight decreases), the support portion 43 at one end of the arm 42 lifts up around the pivot point, and the projection 56 located at the opposite end (point of application) of the arm 42 lowers. This causes the projection 56 to push down the lever 59 of the microswitch 58, which in turn turns on the contact inside the microswitch 58, thereby detecting that the bait has been eaten.
[0065] Furthermore, if the detection unit 50 of the movement detection unit 40 is a microswitch 58, since this involves physical contact, it is necessary to set the load precisely, taking into account the force required to push down the lever of the microswitch 58.
[0066] Thus, according to this fourth embodiment, the detection unit 50 is formed by the microswitch 58, its lever 59, and the projection 56. When the arm 42 rotates, the projection 56 pushes down the lever 59, which turns on the contact inside the microswitch 58, thereby detecting bait consumption and fulfilling the conditions for bait consumption. As a result, the circuit's conductivity is switched from the ON state to the OFF state in the control unit 10, stopping the beacon transmission, and enabling reliable detection of the mouse N at the field terminal 2.
[0067] Next, a fifth embodiment of the bait-feeding detection device (an example with a curved arm) and a sixth embodiment (an example with an attraction structure at the point of application) will be described with reference to Figures 10 and 11.
[0068] First, a fifth embodiment of the bait-feeding detection device (an example of a curved arm) will be described with reference to Figure 10. Figure 10 is a perspective view showing a fifth embodiment of the bait-feeding detection device shown in Figure 3 (an example with a curved arm). The fifth embodiment of the bait-eating detection device 1 uses a coil spring 45 in the movement detection unit 40 that generates a pressing force in the direction of arrow D when bait E is attached, and the arm portion 42a exposed from the rotation axis 41 of the device body is composed of two parts: a curved portion 91 that curves downward and a straight portion 92. A support portion 43 is provided at the end of the straight portion 92.
[0069] In this fifth embodiment, during normal detection operation with the bait E attached to the support portion 43, the downward (direction of arrow D) pushing force of the coil spring 45 balances the load including the arm portion 42a and the bait E, so that the straight portion 92 of the arm is at approximately the same position as the bottom surface of the device body. Furthermore, when the bait E is eaten by the mouse N and the support part 43 becomes lighter, the movement detection unit 40 inside the device body detects that the arm on the side of the point of action being pushed by the coil spring 45 lowers, indicating that the condition for bait consumption has been met. The subsequent movements are the same as in the above embodiment and will not be described.
[0070] As described above, according to the fifth embodiment (example of a curved arm), by configuring the arm portion 42a with two parts, a curved portion 91 and a straight portion 92, the bottom surface of the device body and the straight portion 92 of the arm 42a are at approximately the same position during normal detection operation with the bait E attached, thereby improving the installation stability of the device.
[0071] Next, with reference to Figure 11, a sixth embodiment of the bait-feeding detection device (an example with a structure that attracts the point of action) will be described. Figure 11 is a perspective view showing an example of a sixth embodiment of the bait-feeding detection device shown in Figure 3. As shown in Figure 11, the sixth embodiment of the bait-feeding detection device 1 has the arm structure shown in Figure 10 and is designed to pull the point of action of the movement detection unit 40 downwards. Specifically, the bait-feeding detection device 1 of the sixth embodiment has an arm portion 42a composed of two parts: a curved portion 91 that curves downward and a straight portion 92. The movement detection unit 40 is equipped with a coil spring 46 connected between the arm and the bottom surface of the device. During normal detection operation with the bait E attached, the coil spring 46 pulls the arm downward (in the direction of arrow D) within the device body, so that the bottom surface of the device body and the straight section 92 of the arm are at approximately the same position, as explained in Figure 10. Furthermore, when the bait E is eaten by the mouse N and the support part 43 becomes lighter, the movement detection unit 40 inside the device body detects that the arm on the side of the point of action being pulled by the coil spring 46 lowers, and that the condition for bait consumption has been met. The subsequent movements are the same as in the above embodiment and will not be explained.
[0072] Thus, according to the sixth embodiment (an example with a structure that attracts the point of application), by configuring the arm portion 42a with two parts, a curved portion 91 and a straight portion 92, in the normal detection operation state with the bait E attached, the bottom surface of the device body and the straight portion 92 of the arm are at approximately the same position, thereby improving the installation stability of the device. Furthermore, in the fifth embodiment, if the balance is maintained by the pushing force of the coil spring 45, when the support part 43 becomes lighter due to bait consumption, the self-weight of the point of application side including the coil spring 45 will cause it to move downward due to the lever action. In the case of a physical contact switch, this may weaken the connection force. However, in this sixth embodiment, the coil spring 46 acts to pull the arm, making it possible to more reliably detect that the conditions for bait consumption have been met.
[0073] In the above embodiment, a beacon board 12 that transmits Bluetooth signals (beacons) at predetermined intervals was exemplified as the wireless communication unit (transmitter). However, a passive tab UHF band RFID tag may also be used. That is, the wireless communication unit (transmitter) may be an RFID tag that uses an external RFID reader (e.g., an RFID reader) as a predetermined power source (power source for wireless communication other than bait detection).
[0074] RFID tags consist of an antenna coil pattern printed onto a thin film substrate, and a control chip (tag) that connects to the antenna coil mounted on the film substrate. In the case of this RFID tag, the wireless communication unit can be activated or deactivated by controlling the connection or disconnection of the circuit following the antenna coil using a switch, similar to the case of the beacon mentioned above, thus reducing the effort required compared to Bluetooth signals.
[0075] In the case of RFID tags, when the circuit is in the ON state, the antenna coil is active, and the RFID reader receives the reflected wave from the antenna coil of the UHF band signal transmitted from the external RFID reader, thereby acquiring data on whether the animal is not feeding or is feeding, as described above. Then, when the bait E is eaten by a pest and the condition detection unit 4 detects that a predetermined condition has been met, the antenna coil is switched to a state where communication is impossible.
[0076] As a result, the RFID reader will not receive data at regular intervals, allowing it to detect bait consumption when the return signal of the transmitted signal is interrupted.
[0077] By using an RFID tag as the transmitter, monitoring functionality can be achieved without the need for batteries or other power sources. While RFID tags have a short reading range of only a few meters, requiring personnel to approach the device to operate the RFID reader, the device itself does not require a power source, allowing it to be installed in various locations and used for a variety of purposes.
[0078] Although one embodiment of the present invention has been described above, the present invention is not limited to the embodiments described above, and any modifications, improvements, etc. that can achieve the objectives of the present invention are included in the present invention.
[0079] In the above embodiment, a dry cell battery 13 was used as the power source for the bait detection device 1, but a solar panel capable of generating power even with indoor lighting may be used as another power source. Furthermore, if the device is ceiling-mounted or similar, commercial power may be used as the power source.
[0080] For example, the series of processes described above can be executed by hardware or by software. In other words, the figures shown in Figures 1 to 11 above are merely examples and are not particularly limiting. In other words, it is sufficient for the device to be equipped with a function that can perform the series of processes described above as a whole, and the functional configuration adopted to realize this function is not particularly limited to the examples shown in Figures 1 to 11. Furthermore, the functions implemented in the app may be configured using hardware alone, software alone, or a combination of both.
[0081] When a series of processes are executed by software, the programs that make up that software are installed on a computer or other device from a network or storage medium. The computer may be a computer that is built into dedicated hardware. Furthermore, a computer can be any computer capable of performing various functions by installing various programs, such as a server, a general-purpose smartphone, or a personal computer.
[0082] Such recording media containing programs may consist not only of removable media (not shown) distributed separately from the main unit to provide programs to users, but also of recording media provided to users, etc., that are pre-installed in the main unit.
[0083] In this specification, the step of describing a program to be recorded on a recording medium includes not only processes that are performed chronologically in that order, but also processes that are not necessarily performed chronologically, but are executed in parallel or individually. Furthermore, in this specification, the term "system" refers to an overall system composed of multiple devices, means, etc.
[0084] In other words, the device to which the present invention applies only needs to have the following configuration, and can take on various forms. In other words, the device in the embodiment to which the present invention is applied (for example, the bait-feeding detection device 1 in Figure 1) is, (1) A transmitting unit (e.g., a beacon board 12 in Figure 2) having a circuit that transmits a predetermined signal (e.g., a beacon) using power supplied from a predetermined power source (e.g., a dry cell battery 13 in Figure 2), Based on the fact that the conduction state of the circuit is ON, a switching unit (for example, the control board 11 in Figure 3) switches the conduction state from the ON state to the OFF state when predetermined conditions are met, In order to maintain the ON state of the switching unit (for example, the control board 11 in Figure 3), a weight exceeding a threshold is continuously applied to the first location (for example, the height position A of the support part 43 of the bait E, which is the point of force application relative to the rotation axis 41 (fulcrum) of the arm 42 in Figure 4), and the weight applied to the first location (for example, the height position A of the support part 43) (the weight of the support part 43 and the bait E) becomes less than the threshold (lighter than the biasing force of the coil spring 45 at the point of application (the force pushing or pulling the other end (point of application) of the arm 42)) is detected as the predetermined condition (for example, the bait E in Figure 5 falls off the support part 43), and the movement detection unit 40 (for example, a seesaw structure including the arm 42 in Figure 5 and a detection unit 50 including a photosensor 51, member 52, etc.) detects that the weight applied to the first location (for example, the height position A of the support part 43) (the weight of the support part 43 and the bait E) has fallen below the threshold (lighter than the biasing force of the coil spring 45 at the point of application (the force pushing or pulling the other end (point of application) of the arm 42) is detected as the predetermined condition (for example, the bait E in Figure 5 falls off the support part 43), It is equipped with. This allows for a simple structure that can be used for periodic inspections by building management companies and the like, while reliably detecting the presence of small animals (such as mice N) that are being monitored.
[0085] (2) The condition detection unit (for example, the seesaw structure including the arm 42 in Figure 5 and the detection unit 50) The pivot point (for example, the rotation axis 41 of arm 42 in Figure 5) and The first point that functions as a point of force application (for example, the height position A of the support portion 43 at one end of the arm 42 in Figure 5), A detection unit 50 (for example, a photosensor 51 that detects when the member 52 at the other end of the arm 42 in Figure 5 blocks light) detects when the point of force (for example, the support 43) moves to the second location (for example, the height position B in Figure 5) when the predetermined conditions (for example, when the bait E in Figure 5 falls from the support 43) are met, It holds. In this way, by using the principle of leverage to detect the rotational movement of the arm 42, i.e., the eating of prey, it is possible to detect the presence of the target small animal (e.g., a mouse N) more reliably with a simple structure.
[0086] (3) The detection unit is a magnetic sensor (for example, the magnetic sensor 53 in Figure 7). This allows for non-contact detection of movement on the point of application side of the arm.
[0087] (4) The detection unit is an optical sensor (for example, the photosensor 51 in Figure 6). This allows for non-contact detection of movement on the point of application side of the arm.
[0088] (5) The predetermined power source is a battery (for example, the dry cell battery 13 in Figure 3). This allows the device (for example, the bait detection device 1 in Figure 1) to be installed in a desired location in a place where there are no commercial power outlets, such as in the ceiling.
[0089] (6) The transmitting unit (for example, the beacon board 12 in Figure 3) transmits a wireless signal (for example, a Bluetooth signal) with a range within a predetermined range (for example, a radius of 10m from the source). This allows the device to receive wireless signals on compatible terminals (existing field terminals such as smartphones and tablets), and by simply installing an app, a low-cost function for monitoring bait consumption by pests can be implemented.
[0090] (7) The transmitting unit is an RFID tag that uses an external RFID reader (e.g., an RFID reader) as the predetermined power source. This allows monitoring functions to be implemented without the need for batteries or other power sources.
[0091] (8) A container (e.g., a tray) for holding food for small animals is placed at the first location (for example, at height position A of the support part 43 in Figure 4). This allows for the use of non-solid foods that lose their shape over time, such as powdered, jelly-like, or gel-like foods.
[0092] (9) The signal processing system of an embodiment to which the present invention is applied is The device described in any one of claims 1 to 8 (for example, the bait-feeding detection device 1), A device-compatible terminal (for example, field terminal 2 in Figure 2) having the function of receiving the predetermined signal (for example, a Bluetooth signal) transmitted from the aforementioned device (for example, the bait-feeding detection device 1 in Figure 2), Includes, The aforementioned device-compatible terminal (for example, field terminal 2 in Figure 2) When the reception of the predetermined signal (e.g., a Bluetooth signal) is detected to be interrupted, the signal no-signal detection means (e.g., monitoring function K in Figure 2) outputs information indicating the detection result as signal no-signal information (e.g., to the monitor O's terminal T or website W in Figure 2), Equipped with, This makes it possible to reliably detect at least one of the following: that the device's power has been turned off, or that the bait E has been eaten.
[0093] In addition, a solar panel may be used instead of the dry cell battery 13 described in the above embodiment. The transmitting means may also be a wireless communication unit, in which case an alert may be issued by sending signal no information (message, alert signal, etc.) to the monitor's monitoring terminal, indicating that the signal transmission has been interrupted because the mouse N has eaten the bait E. This allows for a simple structure that can be used for regular inspections by building management companies, and can reliably detect the presence of pests such as rats. [Explanation of Symbols]
