This disclosure relates generally to a pest control system and more particularly to pest monitoring devices wirelessly connected to a device control system.
It is well-known to provide pest traps with bait both within and outside of homes, apartment towers and industrial buildings for capturing and controlling pests, such as ants and other insects, and also other larger pests such as mice and other rodents.
The use of typical pest traps can be described as follows. Some form of bait or other means for attracting a target species of pest to the trap is loaded into the trap, which is then placed in a location where activity of the target species has been observed or would be expected. For example, in a residential home setting, the trap could be placed in areas behind stoves and fridges. In commercial and industrial settings, traps can be placed along walls in warehouses and processing environments and behind furniture and in corners of offices.
The contents of the traps are typically inspected at times that are convenient to a consumer or are scheduled by a pest control professional as part of a maintenance visit. Observations are made as to whether the bait has been consumed and how much bait has been consumed. Conclusions on strategies for controlling the target species of pest are typically made based on these observations. This is a relatively inaccurate method by which strategies for controlling pests can be devised. Between the times the monitoring devices are deployed and the times they are inspected, there is no data available to the homeowner or pest control professional as to whether the devices are proving effective in controlling the population of the target species.
It would therefore be advantageous to be able to provide a pest control system that at least partially resolves the above noted issues by providing more detailed information about the actions of pests of a target species and/or predictions as to the future actions of the pests.
The proposed pest monitoring devices of the pest control system, whether for mice, rats, insects or some other species, are made of at least a bottom container that has an entry aperture at one end and an area for loading the bait. The bait once ingested, may kill the pest. The devices may detect pest activity and actions and communicate data of the pests actions to a person managing the devices, whether it is a consumer or a pest control professional.
A further understanding of the functional and advantageous aspects of the disclosure can be realized by reference to the following detailed description and drawings.
In an aspect, a pest control system is provided for monitoring a target species of pest and includes at least one monitoring device having a plurality of possible states which represent a plurality of actions of the target species of pest, the plurality of actions relating to at least one alterable aspect of the at least one monitoring device.

The at least one dataset is received by the control system 120 for storage and analysis. A local processing unit 108 is provided within each of the at least one monitoring device 102 to control the activation and function of the sensing circuitry 104 and to control the transmission of datasets through the communication circuitry 106 between the at least one monitoring device 102 and the control system 120.
The control system 120 is generally configured to receive at least one dataset of the detected states from each of the at least one monitoring device 102. The control system 120 also includes communication circuitry 112 connected to the wireless communication network 110 and configured to receive at least one dataset transmitted from the at least one monitoring device 102. The control system also includes at least one processor and at least one associated memory 116 and may include multiple processors and associated memory. In an embodiment where the control system is spaced away from a monitoring environment where the device is being used, an intermediate device can be provided between the at least one monitoring device 102 and the control system 120 to relay at least one dataset transmitted from the monitoring device to the control system. In an additional embodiment, the intermediate device is a router installed in the monitoring environment.

In an embodiment, based on an analysis of the stored datasets by the processors 116, if a change in an action of the target species relating to an alterable aspect of the at least one monitoring device 102 is identified, a notification is provided through an interface of the control system 120 that is indicative of the change in the actions of the target species of pest. In an embodiment, this notification indicates that the alterable aspect of the at least one monitoring device 102 should be changed.

In an embodiment of the method, the step of transmitting the at least one dataset further includes the step of storing the at least one transmitted dataset from the monitoring device on a memory of the control system to generate at least one stored dataset, and analyzing the at least one stored dataset collected over a period of time to identify a change in the actions of the target species in response to at least one alterable aspect of the at least one monitoring device.
Referring now to
One or more possible states of the at least one monitoring device that are sensed by at least one sensor of the sensing circuitry can be used to provide information that is indicative of at least one target species action within, on or around the at least one device. In an embodiment, two of the plurality of possible states sensed by the sensing circuitry are the presence or absence of pest of the target species in an interior, bait storage section of the container unit of the device.

The detected location of the at least one device can be transmitted to the control system as an additional dataset and may be stored in the control system as part of the at least one stored dataset or as a separate stored dataset.
The container unit of the device generally has some form of bait storage section access member such as a lid, through which a user can access an interior section of the container unit. In an embodiment, the container unit and access member are preferably made of a rigid, durable plastic such as ABS.

Each bait storage section includes a respective sensor and associated control circuitry as part of the sensing circuitry which are located at respective entrances of each of the bait storage sections.
In an embodiment, the sensing circuitry of the at least one monitoring device includes additional sensors configured to detect a state of the plurality of possible states that is not a presence or absence of a target species. The monitoring device can include a position sensor housed within the bait storage section of the container unit. The bait is placed on top of this position sensor so that the sensor can detect the presence or absence of bait in the bait storage section which is indicative of the bait being consumed by a target species.

In an embodiment presented in

Referring now to
The communication circuitry 402 is connected to a local processing unit 420 housed within the at least one monitoring device and is connected to an electrical power source 430 in the form of one or more batteries 422. The local processing unit 420 housed within the at least one monitoring device is an electronic circuit comprised of one or more components including a memory 412. The local processing unit is also connected to the one or more sensors 416 which are part of the sensing circuitry. The local processing unit 420 controls the activity of each of the sensors of the sensing circuitry and will receive data captured from each of the sensors 416 to package before it is sent over through the communication circuitry 402. More than one processor sub-unit 414 may be included in the local processing unit 410. The circuit of the local processing unit 410 can be comprised of digital circuitry, analog circuitry or both and can be a hardwired state machine or a firmware programmable machine. The local processing unit memory 412 can be comprised of one or more components and can be a variety of types including volatile, nonvolatile, solid state, optical or magnetic, or a combination of any of these varieties. In an embodiment, the local processing unit 410 comprises a programmable microcontroller in a solid-state integrated circuit that integrally includes a processor and memory and is connected to the one or more sensors 416 and to the communication circuitry 402. In an embodiment, the at least one monitoring device also includes one or more indicator lights 418 (i.e. LEDs) which are connected to the local processing unit 410.
The data captured by the sensors 416 of the sensing circuitry can be packaged and transmitted to the control system in various ways. In an embodiment, the communication circuitry 402 is instructed by the local processing unit 410 to send at least one dataset of the detected states of the plurality of possible states to the control system every time one of the sensors 416 detects a change in at least one of the plurality of possible states.
In an alternative embodiment, the communication circuitry 402 is instructed by the local processing unit 410 to send at least one dataset of the detected state of the plurality of possible states along the wireless communication network to the control system at predetermined intervals of time. In this embodiment, the at least one sensor 416 of the sensing circuitry in the at least one monitoring device produces data in response to a difference in the plurality of possible states of the monitoring device. The local processing 410 unit has sufficient local memory 412 to store data associated with each instance of change in a detected state so as to form a local stored dataset. The local stored dataset will store all the datasets generated by the at least one sensor 416 of the sensing circuitry during a particular interval of time before the local dataset is transmitted along the wireless communication network to the control system.
In an embodiment, the at least one monitoring device is configured to only send at least one dataset along the wireless communication network when requested by the control system. The at least one sensor 416 produces data in response to a difference in at least one of a plurality of possible states. Again, the local processing 410 unit has sufficient memory 412 to store data associated with each instance of a detected difference in a state of the plurality of possible states so as to form a local stored dataset. The local stored dataset will store all the datasets sensed by the at least one sensor 416 of the sensing circuitry during a particular interval before the control system requests that the local dataset be sent along the wireless communication network.
In an embodiment, the local processing unit 410 of the at least one monitoring device comprises a processor and an associated memory with stored instructions and sufficient storage space and processing power to enable the local processing unit to analyze at least one local, stored dataset of the multiple, possible states of the device to identify a change in an action of the target species in response to at least one alterable aspect of the monitoring device and produce an analysis dataset. Based on this analysis, the communication circuitry 402 of the at least one device may send the local, stored dataset and/or the analysis dataset to the control system. The control system may be instructed to perform additional analysis on the local, stored dataset or the control system may use the analysis dataset as the basis to provide a set of information and a notification to the user through an interface of the control system. This notification may indicate that an alterable aspect of the at least one monitoring device should be changed. In an embodiment where the pest control system includes more than one monitoring device, some or all of the monitoring devices are capable of locally analyzing at least some aspects of the local, stored dataset acquired by the sensing circuitry of the device to produce an analysis dataset as described previously.
The link between the at least one monitoring device and the local communication server may be wired, however, the preferred embodiment uses some form of wireless communication network to link the at least one monitoring device to the control system. Among the specific technologies for wireless local communication, the wireless communication network may be any one of the following: a WLAN (i.e. an 802.11 standard) network, Bluetooth network, radio frequency network or other similar systems.
In an embodiment, the wireless communication network and associated network hardware is an independent network that already exists within the monitoring environment in which the at least one monitoring device is deployed. In an alternative embodiment, the hardware for generating the wireless communication network is integrated within the control system itself.
In an additional embodiment, circuitry is provided within one of the at least one monitoring device to create a web server locally within the monitoring device. In an embodiment, this circuitry is a Wi-Fi microchip with a full TCP/IP stack and an integrated microcontroller.
In an additional embodiment, the wireless communication network is an encrypted network which limits or prevents interference with other wireless systems in the environment where the at least one monitoring devices is deployed.
As noted previously, the control system 120 is configured to receive datasets of the plurality of possible states of each of the at least one monitoring device 102. The control system 120 includes communication circuitry 112 connected to the wireless communication network 110 and configured to receive the at least one dataset transmitted from the monitoring device 102 over the wireless communication network 110. In an embodiment, the control system includes multiple processors 116 and associated memory. The control system can have multiple control elements contained therewithin, where one of these control elements is a central control unit 114 with a processor and associated memory. The control system may also be configured to connect to the internet 130. In an embodiment, the control system 120 also includes suitable internal hardware 118 for generating the wireless communication network.
The at least one dataset may be received by the control system in a variety of configurations. The received at least one dataset may be just one dataset from one monitoring device of the detected plurality of possible states of that device. The dataset may also be a dataset of the detected plurality of possible states of a device received from each device in a network of multiple monitoring devices. The datasets may be multiple datasets received from each device within a network of multiple monitoring devices. In an embodiment, the control system is configured to receive a dataset from the at least one monitoring device every time one of the sensors of the at least one monitoring device detects a difference in a detectable state of the plurality of possible states of the at least one monitoring device. In an alternative embodiment, the communication circuitry of the control system is configured to receive at least one dataset along the wireless communication network at predetermined intervals of time.
In an embodiment of the system 600 provided in
The control system generally comprises memory for storing at least one dataset received from at least one monitoring device, the memory being configured to store the at least one received dataset as at least one stored dataset for further analysis. In an embodiment, the memory that stores the at least one stored dataset is the associated memory of the central control unit. In an embodiment where datasets are received from multiple monitoring devices, the memory within the central control unit includes one or more databases for storing the multiple datasets of the detected plurality of possible states captured by the multiple monitoring devices. The multiple datasets can include device registration information such as a device ID's or device location information and can also include data of the detected state of the plurality of possible states of the multiple monitoring devices.
The at least one processor and associated memory of the control system include instructions executable by the at least one of processor for analyzing the at least one stored dataset. In a preferred embodiment, the instructions are stored on the memory of the central control unit and executed by the processor of the central control unit. The at least one stored dataset is generally analyzed to identify a difference in the actions of the target species of pest in response to at least one alterable aspect of at least one monitoring device. As noted previously, the at least one stored dataset includes data of one or more possible states of at least one monitoring device that are detected by the sensing circuitry of the at least one device. The detectable states are used to interpret or estimate changes in the actions of the target species in and around the at least one monitoring device. For example, the presence and subsequent absence of a pest of the target species in a bait storage section of the device may be indicative of a pest of the target species entering and leaving the monitoring device. The data of the detected states of the plurality of possible states can be algorithmically analyzed to identify changes in the actions of the target species.
In an embodiment, a first state from the plurality of possible states of the at least one monitoring device which is detected by the sensing circuitry is a presence of an individual pest of the target species in the device. A second state from the plurality of possible states of the at least one monitoring device which is detected by the sensing circuitry is a lack of presence of any of the target species in the device.
In an additional embodiment, a first state from the plurality of states corresponds to a presence of a pest of the target species within the at least one monitoring device and the stored dataset shows a reduced number of detections of the first state, over time. The reduced number of detections over time may be indicative of the target species developing an aversion to the bait in the at least one monitoring device.
In an embodiment, a first state from the plurality of possible states of the at least one monitoring device is a presence of an individual pest of the target species at the pest control system. In this embodiment, the notification provided via the user interface indicates that the type of bait stored within the bait storage section of at least one of the at least one monitoring device should be replaced, based on how many detections of the first state have been made by the sensing circuitry.
The specifics of the data included in the at least one stored dataset influences the analysis which is performed to identify changes in actions of the target species. In an exemplary embodiment, the at least one stored dataset includes data of discrete sums or tallies of the number entries and exits of a target species into multiple monitoring devices, and includes data of the present location of each of the multiple monitoring devices in the environment where the devices are deployed. Algorithms can be applied to analyze the at least one stored dataset to identify improperly placed monitoring devices that the target species are not entering or are not using.
In an embodiment, the at least one stored dataset is a dataset that includes the number of entries of a target species into the bait storage section of a particular monitoring device over time. The at least one dataset can be analyzed by algorithms to identify a decrease in target species entries over time which may signal or predict the target species developing an aversion to the bait held within the particular monitoring device.
In an embodiment where the at least one monitoring devices has multiple bait storage sections each holding a different type of bait, the stored at least one dataset is a dataset that includes the number of individual entries of a target species into the multiple bait storage sections of the at least one device. The at least one dataset can be analyzed to identify a type of bait that is preferred by the target species.
In an additional embodiment, the at least one stored dataset includes the location of multiple monitoring devices and a count over time of the number of target species entries and exits from the bait storage section of each of the multiple monitoring devices. Algorithms can be applied to identify a difference in the actions of the target species of pest at a first one of the monitoring devices as compared to the actions of the target species of pest at a second one of the monitoring devices. The difference in actions of the target species between the devices identified in the data can be indicative of a difference in the consumption of the bait by the target species between the devices. In an additional embodiment, the identified difference in the consumption of bait by the target species between multiple monitoring devices is due to the target species developing an aversion to the bait in some of the multiple monitoring devices.
The central control unit includes a user interface through which information related to the at least one stored dataset is provided. In an embodiment presented in
When the at least one processor of the control system analyze the at least one stored dataset and identify a change in the actions of the target species, a notification 722 can be provided through an interface 702 of the computing device 704 to indicate the identified difference. In an embodiment shown in
The application 710 on the computing device can be configured to provide the user with easily understandable presentations of the collected data from the at least one stored dataset of the at least one monitoring device. In the exemplary embodiment provided in
In an embodiment, the notification provided through the interface can also indicate to the user that the required alterations to the at least one monitoring device should be performed by a certified pest control technician. For example, the notification provided may instruct the certified pest control technician to change the bait with a different type of bait, so as to verify if bait aversion has occurred by the target species. In another example, the notification provided may instruct the certified pest control technician to replace the bait with more of the same bait. This can occur, for example, if the control system has identified that more than a selected threshold number of visits have occurred to a particular monitoring device (whereupon the assumption is made that a certain amount of the bait has been consumed at each visit). Put another way, the provided notification may be indicative that more of the bait should be added to the bait storage section of at least one of the at least one monitoring device, based on how many detections of the first state have been made by the sensing circuitry.
In an embodiment, the application may prompt a user to enter in specific credentials 734 through input means of the user interface to access different levels of the control system. The input mean may be a separate keyboard or keyboard integrated within a touchscreen of the device 732. In an embodiment, there may be one set of credentials associated with a consumer of the device that allows a user to access a consumer-focused version of the application and a second set of credentials associated with an application that is for use by a certified technician. Different data and pages within the application on the computing device can be displayed or restricted according to different access levels.
