Tracking and tracing of shipments are becoming increasingly important worldwide. Logistics and supply chain management firms are increasingly required to possess track and trace capabilities to monitor the movement of each parcel moving from across town to around the globe. Radio frequency identification devices (RFID) or RFID tags are increasingly used to track a large number of different articles. RFID tags are specially seeing widespread use in shipping containers to enable logistics firms to track individual containers as they move through various locations to the customer.
Typically, RFID tags on storage containers or transport units in trucks are tracked and located by portable or stationary reader/interrogator systems such as hand-held readers or dock door portals respectively. However, both hand-held readers and dock door portals have certain disadvantages. For example, a hand-held reader may have a limited means of controlling the RF signal field size in high inventory areas. The dock door portals are not mobile solutions and cannot be easily redeployed. Moreover, in locations such as airports, where the facilities are not owned by the logistics carriers, installing fixed infrastructure is not possible. Moreover, hand held readers require the involvement of a person who must carry the reader and perform the scan, during which time the person cannot help with any loading or unloading activities.
It is also known that RFID readers can be powered by means of AC wall adapter circuits or POE connections whereby power is delivered via a communication cable. RFID readers consume power in an idle state as well as when tasked to perform an inventory read cycle. The reader's antenna ports can be individually selected and turned on or all turned on simultaneously. Each option has an impact on how much power is required to support the load of a read event. Additionally, when reader's ports are selected the firmware in the reader directs the transceiver to rotate through each antenna at a predetermined rate. This works exceptionally well in achieving the highest possible read rate performance, however, this may involve high power consumption. For example, turning on a single antenna may require 1.5 amps but turning on all four antennas in a reader may require more power thus increasing the power consumption.
Higher power consumption is a real concern especially in mobile battery powered world. Batteries no matter what technology or chemistry do not provide longevity when abused such as under deep discharge conditions. Regardless of the type of battery used, there is a need for understanding the battery power requirements based on reader demands. Moreover, compliance of reader designs with regulatory limits such as only one antenna port can be on at any given time must also be considered.
Accordingly, improvements over conventional systems are needed for portable RFID reader systems.

In some embodiments, an integrated reader system is provided for reading radio frequency identification (RFID) tags. In some embodiments, the reader system comprises a reader that continuously/non-continuously monitors an area within a transport unit of a vehicle. In some embodiments, the transport unit is a trailer of the vehicle. In some embodiment, the transport unit may be permanently attached to the vehicle and in other embodiments the transport unit may be detachably attached to the transport unit. The transport unit may have doors, and the area or parts being monitored may include the doors of the transport unit. In some embodiments, the door may be a split swinging door.

The vehicle is provided with an integrated reader system configured to read the RFID tags. In some embodiments, the pallets or parcels may be tagged with both a barcode and an RFID tag.
In some embodiments such as shown in
In some embodiments, the energy storage device 103 is an on-board battery pack built into a main housing of the transport unit. The battery pack may be recharged by one or more means to maintain the battery capacity level.
For example, in some embodiments, the energy storage device 103 is connected to a charging circuit (not shown). The charging circuit may comprise one of a solar cell or a motor generator. In some embodiments, the charging circuit may be functionally connected to a wiring harness of the vehicle. Connection to an independent rechargeable energy storage device 103 allows the reader 101 to read at any time, including during a partial delivery.
In some embodiments, the energy storage device 103 such as the on-board battery pack may be connected to a remote battery unit provided in the transport unit and may be charged by the remote battery unit. The battery capacity of the on-board battery pack is maintained by DC-DC charging from the remote battery unit. The remote battery unit is recharged when the transport unit is connected/attached to the vehicle. Presence of both the on-board battery pack and the remote battery unit are especially useful in vehicles where the transport unit is detachable from the rest of the vehicle. In other words, presence of the on-board battery pack and the remote battery unit allows the reader 101 of the integrated reader system 100 to be charged even when the transport unit is detached from the vehicle, thereby allowing the reader 101 to perform reading even the transport unit is detached from the vehicle.
In some embodiments, the energy storage device 103 such as the on-board battery pack may be connected to a power unit (not shown) in the vehicle, the power unit being used to supply power to electrical components of the vehicle including electrically powered/hydraulic doors or shutters of the vehicle. Thus, an existing power source can be used to charge the on-board battery pack and the on-board battery pack can in turn charge or otherwise power the reader 101.
According to an aspect of the present subject matter, the integrated reader system 100 is configured to control reading performed by the reader 101 based on different operating conditions in the vehicle. For example, in some embodiments, the reading performed by the reader 101 is controlled based on opening or closing of the doors of the vehicle. For example, the one or more readers 101 may be operatively connected to one or more sensors 104, such as a door sensor 104a.
In some embodiments, the door sensor 104a is communicatively connected to the reader 101 via the relay unit 110. Thus, the door sensor 104a is configured to activate the reader 101 based on position and/or movement of the doors 202, such as whenever the doors 202 (shown in
Power states may include one or more of the following, which for some embodiments may represent a sequence of states going from lower to higher power: off, sleep, idle, lower frequency checking, higher frequency checking, low power on, or higher power on. In an off state, the system may be turned off with no power being drawn from power sources. In a sleep state, most power systems may be turned off, but power may continue to be supplied to the processor to allow it to turn other systems back on when needed. In an idle state, one or more sensors 104 may be turned on while the reader 101 is off or at a low power state. In a lower frequency checking state, the reader 101 may be turned on periodically such as once a day, every six hours, every three hours, every hour, every 15 minutes, every 10 minutes, every 5 minutes, every minute, or at a lower or higher frequency. The duration of being powered for the reader 101 may be for 10 minutes, 5 minutes, 1 minute, 30 seconds, 20 seconds, 10 seconds, 5 seconds, 1 second, 500 milliseconds, 250 milliseconds, 100 milliseconds, 10 milliseconds, 1 millisecond, or lower or higher durations. The higher frequency checking state may have one or both of a higher frequency or a longer duration than the lower frequency state. In some embodiments, there may be multiple levels of one or both of lower frequency checking states and higher frequency checking states. During a low power on state, the reader 101 may have a lower power read setting that may be able to detect non-blocked RFID chips between the reader 101 and the opposite boundary of a storage container, such as a floor. In a higher power on state, the reader 101 may be set at a power level that permits greater range and reflections from surfaces within a storage container or transport unit that will more reliably detect RFID tags that are hidden or partially or completely blocked from the reader 101.
In some embodiments, the higher power setting will use more power than other settings. In some embodiments, the higher power setting may be triggered to turn on after detection of an RFID tag that is unexpected, such as during a storage time period, during shipment, and/or during non-business hours. Detection of an RFID tag during an unexpected time period may be an indication of movement of packages that is not desired, damage to boxes holding RFID tagged items, theft of an RFID tagged item, unauthorized movement of packages, or other issues. Moving to a higher power setting may allow detection of all items being stolen, whether their tags are partially blocked or not, a full or more full inventory of the items within the container, trailer, transport unit, or other storage location.
In some embodiments, the reader 101 is communicatively connected to the one or more sensors 104 comprising a trigger sensor, such as one or more motion sensors 104b and/or any other sensors of interest. In some embodiments, the trigger sensor, such as a motion sensor 104b is configured to trigger the RFID reader 101 to come out of an idle state after either detecting something such as motion and/or after a predetermined amount of time has lapsed. For example, even though the RFID reader 101 may be communicatively connected to the door sensor 104a via the relay unit 110, the reader 101 may be configured to go into an idle state if the door sensor 104a is inactive for long durations when the doors of the transport unit are left open and/or after the number of RFID tag detections has fallen below a threshold. For example, the predetermined amount of time may be 1 minute, 2 minutes, 3 minutes, 5 minutes, 10 minutes, 20 minutes, 1 hour, 2 hours, or longer or shorter durations. The trigger sensor, such as the motion sensor 104b, may be configured to activate the RFID reader 101 from such an idle state if the trigger sensor detects activity and/or after a long duration of inactivity. In some embodiments, a timer circuit (not shown) may be operatively connected between the RFID reader 101 and the motion sensor 104a in order to activate the RFID reader 101.
In some embodiments, the cellular communication module 105 communicates to the processor 102 a real time location. For example, the cellular communication module 105 may be used to communicate to the processor 102 various operating parameters that can reconfigure operation of the system. For example, the processor 102 may be configured via the cellular communication module 105 to have one or more real-time locations of the places where the doors of the transport, storage, and/or shipping unit may be opened and/or times and/or dates when the doors may be opened. The cellular communication module 105 communicatively connected to the processor 102 is independent of any other cellular service that may be present on-board the vehicle.
In some embodiments, the integrated reader system 100 comprises a camera 106. In some embodiments, the camera 106 is configured to capture real time images and/or transmit the real time images to the processor 102 and/or to a server under certain conditions. The processor 102 may trigger an alert and/or record an image and/or video when an event, such as a prohibited, scheduled, predetermined, allowed, or unexpected event is detected through one or more components of the system. In some embodiments, the trigger for an event may include when movement of a door is detected. In some embodiments, the trigger for an event may be when a door of the vehicle is left open for a predetermined amount of time. In some embodiments, an event may include when one of the sensors 104 or the reader 101 detects a change in conditions in or around a transport unit 201, such as with respect to detection of movement, reduced light to a light sensor, acceleration above a threshold limit, changes in temperature above or below a threshold, detection of an RFID tag, failure to detect an RFID tag, detection of liquid that might be part of a leak, and other possible incidents.
