    DK 2019 70245 A1 1TITLE AN APPARATUS AND METHOD FOR DETECTING, MONITORING AND/ORCONTROLLING OF RAT ACTIVITY
    TECHNICAL FIELD The disclosure relates generally to detection, monitoring, and control of rat activity in a certain area using sensor- based technology and Internet of Things (IoT) technology.
    BACKGROUND Rats pose a threat to human and animal health and well-being and may cause inconvenlences as well as material losses to industry, society, and households. Particularly, the presence of rats in settings such as production, processing, or storage facilities in the food, agriculture, pharmaceutical, health care, or other high hygiene demanding sectors is undesirable, since rats can carry diseases and parasites and can transmit these to other animals and to humans. Further, rats can damage buildings, structures, and equipment and can spoil food stock. Therefore, there is a need for technology for controlling rat activity.
    It is known to use bait stations holding e.g. poison and/or traps for controlling rodent pest activity, particularly rat activity and mouse activity. However, operating and maintaining a pest control system comprising bait stations
    DK 2019 70245 A1 2 often requires significant labor with a lot of time and money spent on periodically inspecting the bait stations to check e.g. the bait status or, in case traps are used, whether a rat or mouse has been trapped.
    Pest control systems covering e.g. industrial production facilities may comprise multiple bait stations positioned in and around the facilities.
    Routinely inspecting the bait stations is time-consuming since workers must locate, inspect, and document the status of each bait station.
    Often, there are no pests in the traps, or even in the facility, yet costs are incurred for checking the traps.
    Accordingly, there is a need for pest control systems that are less labor intensive.
    Today, inspection is with a typical maximum of twelve inspections per year.
    Consequently, pest control is often initiated with a certain delay after rat activity has occurred.
    Accordingly, there is a need for pest control systems allowing for immediate initiation of pest control upon occurrence of rat activity.
    In settings such as production, processing, or storage facilities in the food, agriculture, pharmaceutical, health care, or other high hygiene demanding sectors, accurate monitoring of pest activity is critical.
    Pest problems need to be identified and responded to quickly.
    Further, often, professional pest control providers managing the pest control of a site will need to gather comprehensive data relating to pest occurrence and behavior and to provide accurate records and reports with key performance indicators of the efficacy and efficiency of the pest control program.
    Therefore, there is a need for pest control technology that allows for automated gathering and analysis of data relating to pest occurrence and for immediate notification to e.g. providers
    DK 2019 70245 A1 3 and/or users of the technology in case pest activity is detected.
    The use of poison, particularly rodenticides, for controlling rats and mice is well-known.
    Rodenticides are applied as biocides in various use scenarios, for example in and around buildings and industrial facilities, in sewers, at waste dumps, and in open areas.
    Often, rodenticides are formulated as baits and placed in bait stations in order to protect the surroundings from direct exposure.
    However, even when placed in bait stations, rodenticides still pose a potential risk to humans, animals, and the environment, e.g. through secondary poisoning of non-target animals such as predatory birds and mammals.
    Further, in certain industrial settings, e.g. in the case of food processing plants, the use of poison is undesirable.
    Further, in e.g. the EU it is not allowed to place poisonous bait before the presence of rats in a rat bait box or in an area where the rat bait box is placed has been detected or determined.
    Thus, one or more rat bait boxes without poison, though possibly with nonpoisonous bait, are to be placed in an area where the presence of rats is suspected and only after determining that rats have entered the box(es) or after otherwise observing rat activity, poison can be used in the rat bait box(es). After placing a rat bait box in an area, an operator will have to revisit the rat bait box at regular intervals, in order to determine whether or not rats have entered the box.
    The need to manually inspect the rat bait boxes which are often geographically widely dispersed creates logistic challenges and results in operators having to travel
    DK 2019 70245 A1 4 substantial distances, thereby using substantial amounts of time and resources.
    SUMMARY It is an object to overcome or at least reduce the problems mentioned above. The foregoing and other objects are achieved by the features of the independent claims. Further implementation forms are apparent from the dependent claims, the description, and the figures. According to a first aspect, there is provided an apparatus for placing in a rat bait box, the rat bait box having a housing closing off an inner space for receiving a rat and bait, the housing being provided with an opening suitable to allow a rat to enter the inner space, the apparatus comprising: an arrangement comprising a floor for forming the bottom of the inner space, the floor being connected to a sensor, the sensor being configured to issue one or more load signals representative of a load or weight on the floor; a processor, the processor having at least a sleep mode and an operating mode, the processor being configured to receive the one or more load signals from the sensor; detection means configured to detect entry of a rat into the inner space; the detection means being configured to send an activation signal to the processor upon detection of entry of a rat into the inner space; the processor being configured to change, for at least a predetermined time span, from the sleep mode to the operating mode upon receiving the activation signal.
    DK 2019 70245 A1
    By providing an apparatus for placing in an existing rat bait box, which apparatus comprises detection means enabling the apparatus to be activated when the detection means detects entry of one or more objects, e.g. a rat, into the inner space 5 of the rat bait box and a sensor for issuing one or more load signals representative of the load or weight on the floor forming the bottom of the inner space, it becomes possible to determine the presence of a rat in the rat bait box and to issue an alert which can e.g. be sent to a remote server about the presence of a rat in the rat bait box.
    The inventors have realized how to achieve automated and differentiated real-time detection, monitoring, and control of rat activity in an area of interest and immediate response upon detection of pest activity using sensor technology installed in one or more rat bait boxes distributed in the area of interest and using IoT technology.
    Automated and digitized inspection of the one or more rat bait boxes is achieved.
    Further, activity occurring in the one or more rat bait boxes is immediately determined and identified and can be responded to immediately.
    Particularly, different kinds of activity occurring in the inner space of the one or more rat bait boxes are identified and distinguished between based on collected load signals.
    The different kinds of activity may be e.g. due to a rat, a mouse, a frog, a snail, snow or leaves blown into the one or more rat bait boxes, etc.
    The collected load signals are representative of the load or weight on the floor forming the bottom of the inner space of the one or more rat bait boxes.
    Owing to the capability of identifying and distinguishing between different kinds of activity, the risk of false alarm is reduced, and the need for human
    DK 2019 70245 A1 6 inspection of the one or more rat bait boxes is minimized, thus saving man-hours and costs.
    Further, the inventors have realized how to render their solution for detecting, monitoring, controlling, and responding to rat activity low in energy consumption by allowing the processor configured to receive and process the load signals to change between a sleep mode and an operating mode depending on the circumstances.
    The apparatus disclosed herein is for placing in a rat bait box.
    That is, the apparatus can be inserted into and operated in an existing rat bait box, which rat bait box may be a conventional rat bait box.
    Thus, the apparatus can be used in a plug-and-play fashion.
    In a possible implementation form of the first aspect, the processor activates the sensor upon changing to the operating mode.
    The effect hereof is that the sensor is activated after detection of entry of a rat into the inner space.
    The sensor is activated for collecting and issuing load signals.
    Prior to activation, the sensor may be in a sleep mode or may be powered off, thus saving energy.
    In a possible implementation form of the first aspect, the processor is configured to change to the sleep mode after the predetermined time span has lapsed.
    The effect hereof is that energy is saved.
    The change to sleep mode may occur e.g. after a fixed max time or when no activity is detected any longer in the inner space by the detection means or the sensor.
    In a possible implementation form of the first aspect, the processor is configured to change to the sleep mode when the detection means and/or the sensor detects that there is no
    DK 2019 70245 A1 7 rat activity in the inner space. The effect hereof is that the processor may enter the sleep mode before the predetermined time span has expired, thus saving battery energy.
    In a possible implementation form of the first aspect, the apparatus comprises a battery for powering the sensor, the processor, and the detection means.
    In a possible implementation form of the first aspect, the detection means comprises a motion sensor, preferably at least one of a PIR sensor, an IR sensor, a vibration switch, an accelerometer, a gravity sensor, and a gyro sensor.

    In a possible implementation form of the first aspect, the apparatus comprises a GPS module and/or a tamper sensor. The effect hereof is that the apparatus, and thus the rat box in which the apparatus is placed, can be located. Thus, in case pest activity is detected in the inner space of the rat bait box, the exact location of the rat bait box, and thus the location of the detected activity, can be determined. Further, it can be determined if the apparatus, and thus the rat box in which the apparatus is placed, changes location. The rat bait box may be provided with other means for identifying and locating the rat bait box, e.g. a barcode, a near-field communication chip (NFC), Bluetooth, etc.
    In a possible implementation form of the first aspect, the sensor comprises a load cell, e.g. a strain gauge load cell.
    DK 2019 70245 A1 8 The effect hereof is that the load or weight of one or more objects on the floor at a given time can be determined and that load signals representative of the load or weight of the one or more objects on the floor can be issued.

    In a possible implementation form of the first aspect, the processor is configured to record the one or more load signals.
    In a possible implementation form of the first aspect, the processor is configured to determine from the one or more load signals whether the one or more load signals are indicative of a rat being or having been present on the floor. The effect hereof is that the presence of a rat in the inner space at a given time can be determined.
    DK 2019 70245 A1 9 In a possible implementation form of the first aspect, the processor 1s configured to determine from consecutive load signals whether the consecutive load signals are indicative of a living rat or a dead rat on the floor. The effect hereof is that the rat, particularly its behavior and activity, can be studied over time. Further, it can be determined whether there is a dead rat occupying the inner space and, thus, whether there is a need for removing a dead rat from the inner space.
    In a possible implementation form of the first aspect, the processor 1s configured to determine from consecutive load signals whether the consecutive load signals are indicative of a trapped rat on the floor. The effect hereof is that the status of a trap placed on the floor in the inner space of the rat bait box can be determined. Thus, it can be determined whether there is a need for removing a trapped rat from the trap.
    In a possible implementation form of the first aspect, the processor is configured to determine a reduction in weight of the bait based on consecutive load signals. The effect hereof is that the status of the bait can be determined.

    DETAILED DESCRIPTION The apparatus and method described herein allow for automated and differentiated real-time detection, monitoring, and control of rat activity in an area of interest and for immediate response upon detection of pest activity using sensor technology installed in one or more rat bait boxes distributed in the area of interest and using IoT technology. Different kinds of activity occurring in the inner space of the one or more rat bait boxes are identified and distinguished between based on load signals. Fig. 1 is a top view of a rat bait box 101 with its top lid removed comprising an apparatus in accordance with an embodiment, and Fig. 2 is a side view of the rat bait box 101 of Fig. 1. The rat bait box 101 has a housing 108 closing off
    DK 2019 70245 A1 19 an inner space for receiving a rat and bait, which housing 108 is provided with at least one opening 106 shaped and sized to allow a rat to enter the inner space.
    The rat bait box 101 comprises an apparatus placed in the rat bait box 101, which apparatus comprises an arrangement comprising a floor 102 for forming the bottom of the inner space. The floor is connected to a sensor 103. The sensor 103 is in an embodiment a load cell configured to issue one or more load signals representative of a load or weight on the floor 102. Further, the apparatus comprises a processor 109. The processor 109 has at least a sleep mode and an operating mode and is configured to receive the one or more load signals from the sensor 103. Further, the apparatus comprises detection means 111 configured to detect entry of a rat into the inner space.
    The detection means 111 are configured to send an activation signal to the processor 109 upon detection of entry of a rat or other animal, such as e.g. mice, into the inner space. Upon receiving the activation signal, the processor 109 changes, for at least a predetermined time span, from the sleep mode to the operating mode.
    The apparatus is provided in the form of an insert inserted into the rat bait box 101 (in another embodiment, not shown, the apparatus is an integral part of a rat bait box). Thus, the apparatus can be used in a plug-and-play fashion by inserting the apparatus into the rat bait box 101 and by, thereafter, operating the apparatus in the rat bait box 101.
    DK 2019 70245 A1 20 Thus, the apparatus can be retrofitted to existing rat bait boxes 101. The floor 102 for forming the bottom of the inner space is suspended and is removable from the rat bait box 101. Suspension means 104, 105 in the form of bottom legs 105 and a top leg 104 for suspending the floor 102 are shown.
    The bottoms legs 105 and the top leg 104 stabilize the floor 102. The bottom legs 105 and the top leg 104 may be provided in the form of an aluminum profile that is stiff enough to not bend under load on the floor 102. The rat bait box comprises a possibly lockable lid 110 or door, which lid 110 or door provides access to the inner space for removing or placing bait and/or a trap and/or for removing a dead rat.
    Further, means for preventing inadvertent access into the inner space though the openings 106 are provided.
    In the embodiment shown in Figs. 1 and 2, the means for preventing inadvertent access into the inner space are provided in the form of vertical plates 107 on the removable, suspended floor 102, which vertical plates 107 form walls extending vertically from the floor 102. The vertical plates 107 are arranged to form a labyrinth.
    Fig. 3 is a top view of a rat bait box 101 with its top lid removed comprising an apparatus in accordance with another embodiment, and Fig. 4 is a side view of the rat bait box 101 of Fig. 3. Fig. 5 is a top view of a rat bait box 101 with its top lid removed comprising an apparatus in accordance with another embodiment, and Fig. 6 is a side view of the rat bait box 101 of Fig. 5. In both the embodiment of Figs. 3 and 4 and the embodiment of Figs. 5 and 6, the means for preventing
    DK 2019 70245 A1 21 inadvertent access into the inner space are provided in the form of vertical plates 107 that are fixed to the housing of the rat bait box 101, which vertical plates 107 form walls extending from the housing of the rat bait box 101 and forming a labyrinth. Fig. 7 is a diagrammatic representation showing the components of an apparatus placed in an exemplary rat bait box 101, the interaction between the components of the apparatus, and the interaction between the components of the apparatus, a cloud server 707, and a user device 708 in accordance with another embodiment. The apparatus comprises a processor 109 that is connected to a transmitter 705 which in turn is connected to an antenna 706 for RF/wireless communication with a cloud server 707. The processor 109 is further connected to a GPS module 704, to a battery 703, to detection means 702, to a tamper sensor 701, and to a load cell 103.
    The GPS module 704 sends a signal to the processor 109 informing the possessor 109 of the position of the apparatus. In another embodiment, no GPS module 704 is provided in the rat bait box 101. Instead, the GPS position of the rat bait box 101 is determined otherwise. For example, a user 709 present at the rat bait box 101 may determine the GPS position of the rat bait box 101 by using e.g. the GPS functionality of his mobile phone. The determined GPS position is then transmitted wirelessly from the user’s phone to the cloud server 707 for storage and/or processing. The battery 703 supplies the processor 109 and the other electronic components
    DK 2019 70245 A1 22 with electrical power. The detection means 702 detects entry of an object, such as for example a rat, into the inner space of the rat bait box 101 and thereby wakes up the processor 109 from a sleep mode. The tamper sensor 701 detects unauthorized tampering with the rat bait box 101 and the apparatus and sends a signal to the processor 109 when a tampering event is detected. The load cell 103 measures the weight on the floor 102 and transmits one or more load signals representative of the weight on the floor 102 to the processor
    109. The load cell 103 is powered when the processor 109 is in its active mode, and the load cell 103 is not powered when the processor 109 is in sleep mode. A user device 708 is wirelessly connected to the cloud server
    707. A user or operator 709 may access the cloud server 707 wirelessly from the user device 708 which may be e.g. a personal computer. The processor 109 is provided with a software that controls its functionality. The processor 109 is configured to receive an interrupt from the detection means 702 when the detection means 702 detects activity of an object in the inner space. Upon receipt of the interrupt, the processor 109 changes from sleep mode to active mode and starts powering the load cell
    103. The processor 109 records the one or more load signals received from the load cell 103. The processor 109 transmits the one or more load signals to the cloud server 707 for determining whether the one or more load signals indicate a weight that corresponds to the presence of a rat. On the cloud server 707, the one or more load signals are associated with
    DK 2019 70245 A1 23 other information stored on the cloud server 707, e.g. information about the position of the rat bait box 101. The cloud server 707 is configured to alert the user device 708 of a user or operator 709 when the presence of a rat has been determined based on the one or more load signals. The user 709 can review the information on the cloud server 707 or on his user device 708 and take appropriate action, such as sending another operator to the rat bait box 101 concerned to place a poisonous bait in the rat bait box 101.
    Fig. 8 is a flowchart of an embodiment of a method for detecting, determining, and controlling rats. From the start of the method, the detection means 111 is allowed to detect entry of an object, e.g. a rat, into the inner space in a rat bait box 101 and to detect activity, particularly movement, of an object, e.g. a rat, in the inner space of a rat bait box 101.
    When the detection means 111 detects entry of an object into the inner space or activity in the inner space, step 801, the detection means 111 sends an activation signal to the processor 109, thereby activating the processor, step 802, i.e. the processor 109 changes from its sleep mode to its operating mode. The activated processor 109 activates the load cell in step 803.
    Upon activation of the load cell 103, step 803, the load cell 103 issues one or more load signals representative of a load or weight on the floor 102 forming the bottom of the inner space, step 804. The one or more load signals are received
    DK 2019 70245 A1 24 and recorded by the processor 109, and the one or more load signals are processed in order to determine from the one or more load signals whether the one or more load signals are indicative of the presence of a rat on the floor 102, step
    805. In an embodiment, the one or more load signals are processed locally in the rat bait box 101 by the processor 109 in order to determine whether the one or more load signals are indicative of a rat being present or having been present on the floor 102. In another embodiment, the one or more load signals are processed externally on a remote server 707, e.g. a cloud server, for determining whether the one or more load signals are indicative of a rat being present or having been present on the floor 102. In step 806, a poisonous (or non-poisonous) bait or a trap is placed in the inner space in the rat bait box 101 by an operator 709 after it has been determined from the one or more load signals that a rat has been present on the floor
    102. In step 806, the poisonous or nonpoisonous bait or trap can also be placed in any rat bait box in the vicinity of the rat bait box where the presence of the rat has been determined, i.e. the determination of the presence of rats does not only encompass the inner space of the rat bait box concerned, but also covers the close proximity, which includes at least a radius of approximately 5 to 25 meters. In another embodiment, poisonous bait or a trap may be placed in the inner space in the rat bait box 101 by an operator 709 only after it has been determined that multiple rats have been present on the floor 102.
    DK 2019 70245 A1 25 Regardless whether action is taken by the operator 709, the method returns to the loop of detecting activity.
    The processor 109 is configured to change to sleep mode after a predetermined time span has lapsed or when no activity is detected any longer in the inner space by the detection means
    111.
    Fig. 9 is a diagrammatic representation of a wireless network of rat bait boxes 101, base stations 902, a cloud server 707, and user devices 708 in accordance with another embodiment. The rat bait boxes 101 form a plurality of rat bait boxes 101, which plurality of rat bait boxes 101 are wirelessly connected to a cloud server 707 through radio frequency (RF) means installed in each of the rat bait boxes 101, thus allowing for transfer of e.g. load signals from the rat bait boxes 101 to the cloud server 707 for storage and/or processing of the load signals and/or for allowing for transmittal of a message from one or more of the rat bait boxes 101 to the cloud server 707, e.g. indicating that a rat has been detected in the rat bait boxes 101 concerned. The cloud server 707 is connected to a wireless and/or fixed network with user devices 708, thus allowing users 709 to access the load signals stored and/or processed in the cloud server 707 and allowing users 709 to be notified that a rat has been detected in one or more of the rat bait boxes 101. In an embodiment, the cloud server 707 is provided with software that is configured to control the logistics of operating the plurality of rat bait boxes 101. Thus, the
    DK 2019 70245 A1 26 software on the cloud server 707 will be configured to issue information about activity detected in one or more rat bait boxes 101 of a plurality of rat bait boxes 101 to an operator 709 that is responsible for managing the plurality of rat bait boxes 101 concerned.
