Description

BACKGROUND

This invention relates to the field of trip monitoring systems and methods, and more particularly, to a system and method for controlling the operation of Bluetooth-based monitoring devices associated with shipments and storage spaces.

Existing monitoring devices employed in containers of shipments and/or storage spaces are typically Bluetooth-based, which monitor ambient conditions of the containers or the storage space and log the monitored ambient conditions as logged data in their local memory. These monitoring devices are started manually or via Bluetooth (BLE) by users to monitor the ambient conditions when a trip is in transit or before the start of trip and again manually stopped at a destination location to extract the logged data. Once the device is at the destination location, the users use Bluetooth connectivity and/or a USB channel to extract the logged data. However, sometimes the user may forget to switch back the monitoring device to start mode while placing the device in the containers or storage space, which may lead to trip being not monitored during the transit.

The following is a detailed description of embodiments of the disclosure depicted in the accompanying drawings. The embodiments are in such detail as to clearly communicate the disclosure. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the subject disclosure as defined by the appended claims.

Various terms are used herein. To the extent a term used in a claim is not defined below, it should be given the broadest definition persons in the pertinent art have given that term as reflected in printed publications and issued patents at the time of filing.

Referring to FIG. 1, a system for controlling the monitoring devices of a container or a truck associated with a shipment is disclosed. The system 100 may include multiple monitoring devices 102-1 to 102-N (collectively referred to as monitoring devices 102, herein) that may be configured in one or more containers 104 (collectively referred to as containers 104 or individually referred to as container 104, herein) assigned by the shipment service provider for a shipment. The monitoring devices 102 associated with a single shipment may be assigned a unique trip-id. These monitoring devices 102 may be configured to monitor attributes of different zones within the corresponding container 104. The detailed operation and functional modules of the monitoring device 102 are described further in conjunction with FIGS. 3 and 4. The container 104 can be a movable container such as a trailer, box truck, and the like, and the zones can be a freezer, cooler, ambient zone, and the like.

The monitoring devices 102 may be configured to be switched between a first mode, and a second mode. The first mode may correspond to a start mode of operation where the monitoring device monitors the attributes associated with the containers 104. The second mode may correspond to a stop mode of operation where the attributes monitoring of the containers 104 by the corresponding monitoring device 102 is stopped, however, the monitoring device 102 remains in a switched-on condition.

Further, the monitoring devices 102 in the second/stop mode may be configured to be operatively connected to one or more external devices (not shown) to allow the extraction of stored data pertaining to the monitored attributes of the containers 104. The external devices may be one or more of mobile phones, computers, laptops, tablets, servers, databases, and the like, where the attributes monitored/recorded by the monitoring devices during transit may be stored when the shipment reaches intermediate locations or a destination during a trip. In one or more embodiments, the external devices may be wirelessly connected to the monitoring devices through a network to allow the extraction of stored data pertaining to the monitored attributes of the containers 104. In one or more embodiments, the external devices may be operatively connected to the monitoring devices 102 through a USB channel or wired media to allow the extraction of stored data pertaining to the monitored attributes of the containers 104.

Referring to FIG. 2, system for controlling monitoring devices of an area of interest (AOI) is disclosed. The system 200 may include multiple monitoring devices 102-1 to 102-N (collectively referred to as monitoring devices 102, herein) that may be installed at one or more locations of an AOI 202, which may be assigned by a service provider for storage and logistics operations. The monitoring devices 102 associated with the AOI 202 may be assigned a unique id. These monitoring devices 102 may be configured to monitor attributes of different zones or locations within the corresponding AOI 202. The detailed operation and functional modules of the monitoring device 102 are described further in conjunction with FIGS. 3 and 4. The AOI 202 may be a storage space, warehouse, and the like, and the zones can be a freezer, cooler, ambient zone, and the like at the AOI.

The monitoring devices 102 may be configured to be switched between a first mode, and a second mode. The first mode may correspond to a start mode of operation where the monitoring device 102 monitors the attributes associated with the AOI 202. The second mode may correspond to a stop mode of operation where the attributes monitoring of the AOI 202 by the corresponding monitoring device 102 is stopped, however, the monitoring device 102 remains in a switched-ON condition.

Further, the monitoring devices 102 in the second/stop mode may be configured to be operatively connected to the external devices to allow the extraction of stored data pertaining to the monitored attributes of the AOI 202. The external devices may be one or more of mobile phones, computers, laptops, tablets, servers, databases, and the like, where the attributes monitored/recorded by the monitoring devices 102 for a predefined time during the first mode may be stored. In one or more embodiments, the external devices may be wirelessly connected to the monitoring devices 102 through a network to allow the extraction of stored data pertaining to the monitored attributes of the AOI. In one or more embodiments, the external devices may be operatively connected to the monitoring devices 102 through a USB channel or wired media to allow the extraction of stored data pertaining to the monitored attributes of the AOI.

Referring to FIGS. 1 and 2, the monitoring device 102 in the first mode may be configured to generate and transmit a set of beacon signals at a predefined interval. The set of beacon signals may comprise data pertaining to the assigned id of the corresponding monitoring device and a status indicative of the first mode. Further, the monitoring device 102 in the second mode may be configured to listen or detect the set of beacon signals transmitted by other monitoring devices 102 that are in the start mode. Accordingly, the monitoring device 102 in the second mode may analyze the detected set of beacon signals and automatically switch to the first mode or AutoStart when the trip-id of the corresponding monitoring device in the second mode matches with the trip-id of the monitoring device transmitting the beacons signals in the first mode, however, their operating status or mode do not match. Thus, even if the user fails to manually switch the monitoring device(s) 102 back to the first mode after collecting the stored data, the monitoring device(s) in the second mode may AutoStart or switch to the first mode as its companion monitoring devices that have the same trip-id and are already in the first mode.

For instance, as shown in FIG. 4, the monitoring devices 102-1, 102-3, and 102-4 may be in the first mode when the container 104 is in transit during a trip or when the event monitoring at the AOI 202 is in process. The user may manually switch the monitoring devices 102-1, 102-3, and 102-4 to the first mode before the transit or the event monitoring process. However, the user may fail to manually switch the monitoring device 102-2 to the first mode. In such case, the monitoring devices 102-1, 102-3, and 102-4 (in the first mode) may generate the beacon signals, at predefined intervals, comprising the unique id and the status indicating that monitoring devices 102-2 have to be in the first mode. Further, the monitoring device 102-2 may detect or listen the beacon signals transmitted by any of the monitoring devices 102-1, 102-3, and/or 102-4 based on the Bluetooth coverage of the corresponding monitoring devices 102. The monitoring device 102-2 may match its unique id and status with the unique id and status extracted from the beacon signals. Accordingly, the monitoring device 102-2 in the second mode may AutoStart or switch to the first mode as its companion monitoring devices 102-1, 102-3, and 102-4 that have the same trip-id and are already in the first mode.

Referring to FIG. 3, the functional modules of monitoring device 102 of the system 100, 200 are illustrated. The monitoring device 102 comprises a processing unit comprising one or more processor(s) 302 operatively coupled to a memory 304.

In one or more embodiments, monitoring devices 102 allow an admin to define or configure a trip automation rule for the shipment and/or the event monitoring protocol for the AOI. The admin can define or configure the trip automation rule or event monitoring protocol as per their requirements using a desktop application. The admin may assign a unique trip-id to the containers associated with a single shipment. Further, the admin may assign a unique id to the locations associated with the AOI for event monitoring. The assigned unique id of the monitoring devices remains stored in the memory 304, which may then be modified by the admin once the trip or event monitoring is completed.

Further, for each container of the shipment or the locations at the AOI to be monitored, alarm conditions can be defined in the trip automation rule or event monitoring protocol for each zone within the containers or the locations at the AOI, respectively. These conditions can be implemented as per expert guidance or as per the user's unique monitoring requirements. The elements for each zone specification alarm include severity of alarm (information, warning, critical), sensor type to be monitored (temperature, light, CO₂, humidity), alarm frequency per trip (once, continuous, reset after raising, reset after acknowledging), alarm type (single, continuous, cumulative, degree minutes, rate of change), alarm threshold in time (days, hours, minutes), threshold type (high or low), sensor threshold (degrees for temperature, and percentage for light, CO₂, humidity), and zone specifications variables for each sensor type (low, ideal, high), but not limited to the like.

For each shipment, a container group can be defined by the admin in the trip automation rule, which includes a grouping of 1 to N containers. Further, a set of monitoring devices 102 is assigned to a specific container that is assigned to a specific container group defined in the trip automation rule. The serial number of each container and the assigned monitoring devices 102 for each container are saved in the database associated with the system 100 for future validation. Further, all the monitoring devices 102 associated with each shipment may be assigned a unique trip-id, which may also be saved in the database associated with the system 100.

For each location of the AOI, a set of monitoring devices 102 is assigned to a specific location that is defined in the event monitoring protocol. The serial number of the assigned monitoring devices for each location at the AOI are saved in the database associated with the system 200 for future validation. Further, all the monitoring devices associated with each location or the AOI may be assigned a unique id, which may also be saved in the database associated with the system 200.

Referring to FIG. 5, exemplary steps involved in a method for controlling the operation of monitoring devices associated with an area of interest (AOI) are illustrated. Method 500 involves a plurality of monitoring devices 102 of FIG. 3 that are assigned a unique trip-id and installed at one or more locations in the AOI. The AOI may be one or more container associated with a shipment as already elaborated in detail in FIG. 1. Further, the AOI may also be one or more room associated with a storage area or storage space as already elaborated in detail in FIG. 2. Each of the monitoring devices may be configured to be switched between a first mode, and a second mode. The first mode corresponds to a start mode of operation where the monitoring device monitors and stores attributes of the AOI. Further, the second mode corresponds to a stop mode of operation where the attributes monitoring by the corresponding monitoring device is stopped and the monitoring devices in the second mode may be configured to be operatively connected to one or more external devices to allow extraction of stored data pertaining to the monitored attributes of the one or more container.

Method 500 includes step 502 of generating, by the monitoring devices, a set of beacon signals at predefined intervals when the corresponding monitoring device is operating in the first mode. The set of beacon signals may comprise data pertaining to the unique id of the corresponding monitoring device and a status indicative of the first mode. Method 500 includes step 504 of detecting, by the monitoring device, the set of beacon signals when the corresponding monitoring device is operating in the second mode. The monitoring devices in the second mode may be configured to automatically switch to the first mode based on analysis of the detected beacon signals.

Method 500 further includes step 506 of extracting, by the monitoring device in the second mode, the unique id and the status (start mode status) from the beacon signals received from the monitoring devices that are in the first mode. Further, method 500 includes step 508 of automatically switching the monitoring devices from the second mode to the first mode upon a negative matching of the extracted status and the status of the corresponding monitoring device and a positive matching of the extracted trip-id and the trip-id of the corresponding monitoring device.

Method 500 further includes step 510 of the steps of operatively connecting the monitoring devices in the second mode to one or more external devices to allow extraction of stored data pertaining to the monitored attributes of the AOI.

Accordingly, the monitoring device in the second mode may analyze the detected set of beacon signals and automatically switch to the first mode when the trip-id of the corresponding monitoring device in the second mode matches with the trip-id of the monitoring device transmitting the beacons signals in the first mode, however, their operating status or modes do not match. Thus, even if the user fails to manually switch the monitoring device(s) back to the first mode after collecting the stored data, the monitoring device(s) in the second mode may autostart or switch to the first mode as its companion monitoring devices that have the same trip-id and are already in the first mode.
