2. FIELD OF THE INVENTION

The presently disclosed subject matter relates to asset tracking for waste and recycling containers.

3. DESCRIPTION OF THE RELATED ART

Roll-off containers, front-end-load containers and intermodal containers can be utilized in connection with waste and recycling pick-up services for customers. Some of these containers are frequently prone to being moved to a different parts of a customer location, causing collections drivers to lose track of the containers within a facility.

Additionally, in some areas, intermodal containers are frequently passed between multiple transportation partners and visibility to their location is lost as they are transferred between different modes of transport.

Additionally, out of service containers can be located at container shops waiting to be deployed to future customer locations. Sales and operations teams often do not have great insight into what container assets are available and look to purchase new equipment instead of using what is already available at existing container shops and similar locations.

Improvements in this field of technology are desired

DETAILED DESCRIPTION

The presently disclosed subject matter relates to asset tracking for waste and recycling containers. In certain illustrative embodiments, a low-cost GPS location asset tracker can be provided for tracking the whereabouts of waste and recycling containers.

Schematics of illustrative embodiments of an asset tracker10are shown inFIG.1AandFIG.1B. Asset tracker10can include various combinations of: a housing20attachable to the waste container; a primary control board comprising an application processor30; a power management system35; an accelerometer40; a battery pack50; and a tracking system consisting of: a GPS receiver60, a low noise amp (LNA)65; an internal GPS antenna70aand/or external GPS antenna70b, a cellular transceiver80, a cellular antenna90atraced directly onto the primary control board; and a SIM/eSIM95. In certain illustrative embodiments, the various components of asset tracker10can be housed inside of housing20. A cellular antenna90aexternal to the housing can also be utilized.

Most current products in this space are “fully loaded,” containing a number of technologies designed to establish the location of containers including GPS, cellular, LORAWAN, wifi, etc. By comparison, in certain illustrative embodiments, the presently disclosed asset tracker10will seek to use only the minimum number of technologies—e.g., GPS and cellular—in order to produce the desired functioning device at reduced cost.

In certain illustrative embodiments, the asset tracker10can include a chipset on primary control board30such as (but not limited to) a Nordic Cellular and GPS chipset (nRF9160), configured to minimize the size and cost of the enclosure. The asset tracker10can also utilize 2 (two) AA batteries in battery pack50that are estimated to provide up to 5 years of battery life. The asset tracker10can be equipped with an accelerometer40, in order to maximize battery life and minimize GPS locking durations. The accelerometer40can act as a mechanism to trigger a report of a motion event. The asset tracker10can be equipped with a timer to enable a wake from low power mode and to prompt the asset tracker10to look for new GPS coordinates or repeat/reuse the existing coordinates if the asset tracker10(and therefore, the container) has not moved within a set number of recording intervals. This functionality can save battery life by not waiting for the GPS lock to occur and keeping the device on longer than needed.

In certain illustrative embodiments, the asset tracker10can include a large housing20for housing the components thereof, as shown inFIG.2. The housing20can be attached directly to the waste container, in order to maintain a weatherproof design. The electronics for the asset tracker10can be placed on a control board located vertically in parallel to the mounting surface.

In certain illustrative embodiments, the asset tracker10can be enclosed via a plate110running along the backside of the housing100and sliding into established holes in each corner, as shown inFIG.3, that can be sealed via O-ring.

Various illustrative embodiments of the primary control board (PCB)120for the asset tracker10are shown inFIGS.4-6. Primary control board (PCB)120ais shown inFIG.4, primary control board (PCB)120bis shown inFIG.5, and primary control board (PCB)120cis shown inFIG.6. In certain illustrative embodiments, the asset tracker10can include an antenna90afor the cellular radio. The antenna90can be traced directly onto the primary control board (PCB)120in lieu of a cellular antenna chip (see the left side of the images inFIGS.4-6). This will result in lower manufacturing costs due to less manufacturing time and the added cost of an externally-located antenna.

In certain illustrative embodiments, the asset tracker10can utilize strictly location-based asset management using only GPS and cellular. Many existing designs are focused on the automation of waste management processes, such as unlocking the container, fill sensors, etc., rather than asset management as described herein.

In certain illustrative embodiments, the asset tracker10can be configured to limit the amount of communication with the cellular network to minimize power usage and optimize battery life, (thus making the device last longer) as well as limit the amount of data usage and associated costs. A diagram of this process130is shown inFIG.7.

In certain illustrative embodiments, two-way messaging can be established, and such configuration of communications may be adjusted using a series of configuration codes that identify configuration states that may include variable parameters such as wake frequency, frequency of location measurement, communication frequency, etc. A diagram of this process140is shown inFIG.8.

A system state diagram150for an illustrative embodiment of the asset tracker10is shown inFIG.9. The diagram150indicates the various events in the process which causes a “trigger” in order to move on to the next state.

In certain illustrative embodiments, the asset tracker10will be capable of starting up and acquiring a signal at regular intervals, such as daily by default, but can be configured to only transmit new coordinates (via cellular network) when those coordinates have significantly changed. Otherwise, it will either submit no signal or submit a different message indicating no movement. This will significantly reduce the amount of data transmitted and extend battery life. A diagram for this process160is shown inFIG.10.

In certain illustrative embodiments, the asset tracker10can utilize logic to detect movement, acquire a GPS signal, and report location. A motion detection flow diagram170for an illustrative embodiment of the asset tracker10is shown inFIG.11. The motion detection flow diagram170focuses on accelerometer functionality as well as the 24-hour timer used in conjunction with detecting motion events from the accelerometer. By using the ability to detect motion events, which will occur when the asset tracker10and attached waste container are moved, the asset tracker's use of battery power should be more efficient. The asset tracker10can also keep track of the last time the GPS location was reported to the cloud, by using a 24-hour timer and counting the number of times a motion event was detected during that period.

In certain illustrative embodiments, the motion detection steps can include: (i) accelerometer will check movement; (ii) if movement detected, will exit low power mode and record a motion event; (iii) upon elapse of 24-hours or other programmed interval, the asset tracker10can utilize logic to count the number of motion events during recorded interval; (iv) if motion events are recorded, asset tracker10can acquire new GPS coordinates, and report its new location back to the cloud via a LTE-M network; (v) if motion events are not recorded, asset tracker10can utilize logic to count the number of 24-hour or other programmed intervals since last report of motion events; and (vi) if number of 24-hour or other programmed intervals is above a programmed threshold, such as 6 days by default, asset tracker10can acquire GPS coordinates and report its location back to the cloud via a LTE-M network.

Additionally, in certain illustrative embodiments, the asset tracker10can use a cellular network to acquire GPS ephemeris data and augmented GPS/A-GPS data to accelerate speed of location acquisition via GPS satellite.

While the presently disclosed subject matter will be described in connection with the preferred embodiment, it will be understood that it is not intended to limit the presently disclosed subject matter to that embodiment. On the contrary, it is intended to cover all alternatives, modifications, and equivalents, as may be included within the spirit and the scope of the presently disclosed subject matter as defined by the appended claims.
