Increasing emphasis is being placed upon accountability and sustainability of food commodities that travel through supply chains to reach end consumers. Consumers are coming to demand that the items they purchase are available at the peak of freshness and have been produced in a socially, environmentally, and economically sustainable manner. For example, every product obtained through a supply chain carries with it a carbon footprint, water usage, raw material usage, etc. that were required to produce and transport the product to the consumer. Opportunities exist for technical solutions to be developed that enable consumers, businesses, and regulatory agencies alike to gain insights as to the sustainability, quality, and nutritional value of food commodities, and particularly produce and other perishable food, passing through such supply chains, and deepen understanding of how food commodities move through supply chains to technologically enable increased accountability for the handling of those food commodities throughout the supply chains.
To address the issues discussed herein, a tracking system for a food commodity supply chain is provided. According to one aspect, the tracking system comprises a tracking device and at least one computing device. The tracking device is configured to be mounted to a conveyance structure configured to receive a unit load of a food commodity traveling along the food commodity supply chain. The tracking device includes at least one sensor configured to track at least one environmental condition of an environment of the tracking device while the tracking device is traveling along the food commodity supply chain. The at least one computing device has at least one processor, which is configured to receive an environmental value of the at least one environmental condition sensed by the at least one sensor, and process the environmental value to determine whether the at least one environmental condition is within a predetermined range. When the at least one environmental condition falls outside the predetermined range, the processor is configured to transmit an alert, and the alert includes a suggested interventive action based on the at least one environmental condition that falls outside the predetermined range.
In some configurations, the tracking system includes a communication hub configured to receive, store, and transmit data from the tracking device. The communication hub includes at least one of a Satellite Communications (SATCOM) module and a terrestrial communications module. The communication hub is configured to switch between the SATCOM module and the terrestrial communications module in accordance with signal conditions.
In some configurations, the tracking system includes a location determination subsystem configured to determine a location of the tracking device as it travels along the food commodity supply chain. The location determination subsystem includes at least one of a SATCOM module and a terrestrial communications module. The SATCOM module includes a Global Positioning System (GPS) element configured to determine GPS coordinates of the tracking device, and the terrestrial communications module is configured to exchange signals with terrestrial access points towers.
In some configurations, the tracking device includes an Inertial Measurement Unit (IMU) module configured to determine IMU values of the tracking device. The processor is configured to receive IMU values of the tracking device, and process the IMU values to determine whether the IMU values are within a predetermined range. When the IMU values fall outside the predetermined range, the processor is configured to transmit an alert.
In some configurations, the sensor is selected from the group consisting of temperature sensor, humidity sensor, gas sensor, air quality sensor, and light sensor, and the system also includes at least one pressure sensor configured to measure a load placed on the conveyance structure.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.
As products move along supply chains, they may be exposed to various conditions in the environment. However, such information frequently remains unknown, as tracking and measuring the conditions experienced by a commodity in transit can be difficult to achieve. While many commodities are unaffected by fluctuations in temperature, humidity, air quality, and the like, such conditions can be detrimental to the quality of other products. The issue of tracking environmental conditions along the supply chain is particularly impactful for perishable commodities, such as produce, as information that is lost between the harvest stage and the distribution stage may lead to the premature ripening of the produce and thus a decrease in quality, nutritional value, and/or shelf-life. This information loss can also lead to food loss when the environmental conditions result in significant decline in quality that renders the produce unfit for sale. Further, the failure to maintain stable conditions during transport and storage can lead to significant nutrient loss, which goes largely unaccounted for in conventional food commodity supply chains. While some solutions to collecting environmental data at farming locations and storage facilities have been implemented, a technical challenge exists in effectively tracking the environmental conditions experienced by commodities as they move along the supply chain.
Utilizing the systems and methods described herein, environmental conditions of commodities can be tracked and measured as the commodities are transported along a supply chain. For example, in a produce supply chain, changes in conditions such as temperature, humidity, air quality, light, and exposure to gases can lead to changes in flavor or texture of the produce, as well as expedited ripening. Tracking and measuring such information can be used to reduce loss, maintain quality and nutritional value, and increase the sustainability of supply chain operations, as described below. Although described primarily in the context of food supply chains, the systems and methods described herein also have applicability to commodities transported in unit loads, such as electronic equipment and devices, medical supplies, pharmaceuticals, personal hygiene products, and household cleaning supplies.
To address the above identified issues, a tracking system 100 for a food commodity supply chain is provided. Referring initially to
Continuing with
The predetermined range may be provided by a user, such as a grower, distributor, purchaser, or a regulatory body with jurisdiction over the supply chain, as values of the predetermined range may differ according to the type of food commodity. Predetermined ranges for example food commodities are provided below in Table 1.
Further, it will be appreciated that these predetermined ranges may be combined using combinatorial logic functions that if met trigger the alert discussed herein to be transmitted. For example, each of a set of conditions may be required to be met, at least one of a set of conditions may be required to be met, or a subset of a set conditions may be required to be met prior to transmitting the alert, as some specific examples. Alternatively, instead of the determining whether the environmental value is within the predetermined range discussed herein, the system may be configured to detect whether the environmental value falls above a maximum threshold or falls below a minimum threshold for the value.
The tracking device 10 may additionally include an Inertial Measurement Unit (IMU) module 32 that is configured to determine IMU values of the tracking device 10, which may indicate a shift in position or load of the conveyance structure 26 to which the tracking device 10 is mounted. In some implementations, the conveyance structure 26 may be equipped with a pressure sensor 34 configured to measure a load placed on the conveyance structure 26, which may also indicate a shift in position or load of the conveyance structure 26. When multiple conveyance structures 26 are stacked, the pressure sensor 34 may be used to determine the position of the conveyance structure 26 in the stack, as a value of the pressure sensor 34 will detect a weight load placed on the conveyance structure 26 in addition to the unit load 28.
To minimize its carbon footprint, it is preferable for the tracking device 10 to be an ultralow-power device. To this end, the tracking device 10 may include a timer 36 to control power supplied to the tracking device 10 such that data from the sensor 30 is collected at specific time increments rather than continuously. The timer 36 may supply power to the tracking device 10 at a preprogrammed time or in preprogrammed periods. When powered on, the tracking device 10 collects data from the sensor 30, including an environmental value of the environment of the tracking device 10. Data from the IMU module 32 may also be collected at this time. Once collected, the data 38 from the tracking device 10 may be transmitted by a transceiver 40 included in the tracking device 10, and the timer 36 may be configured to cut power to the tracking device 10 until the next data collection timepoint. To further minimize power usage, the tracking device 10 may be configured to communicate according to Bluetooth Low Energy (BLE) standards, for example. Additionally or alternatively, the tracking device 10 may be configured to transmit data without a battery or power source via Radio Frequency (RF) backscatter, for example. Accordingly, the transceiver 40 may be configured as a BLE module and/or an RF backscatter module.
In some implementations, the tracking device 10 includes a passive radio frequency (RF) tag that is configured to emit a tracking signal when bombarded by radio waves from an interrogating RF transceiver. The RF tag may be configured as an RF identification (RFID) tag 42 that emits a unique tag identifier, for example. The passive RF tag 42 enables identification of the tracking device 10 as it travels along the supply chain. In addition to the identification of the tracking device 10, the RFID tag 42 may be configured to emit values from one or more sensors 30, such as a temperature sensor, for example.
The tracking device data 38, including data from the sensor 30 and the IMU module 32, as well as the identification of the tracking device 10, may be transmitted from the tracking device 10 to a communication hub 44 included in the tracking system 100. The communication hub 44 may be installed in a vehicle, such as a truck, ship, or airplane, for example, that is used to transport the food commodity along the supply chain. Additionally or alternatively, the communication hub 44 may be located in a storage facility or a warehouse at which the food commodity is temporarily held as it moves along the supply chain. The communication hub 44 is configured to receive the tracking device data 38 via a transceiver 46 included in the communication hub 44. Like the transceiver 40, the transceiver 46 may be configured to communicate via BLE standards and/or RF backscatter, for example. When configured to include an RF module, the transceiver 46 may function as the interrogating RF transceiver for the RFID tag 42 on the tracking device 10. Once received, the tracking device data 38 may be stored at the communication hub 44 in memory 48. In some implementations, the communication hub 44 may be configured as an edge computing device that is capable of performing elementary computational functions on the tracking device data 38.
To transmit the tracking device data 38 to the server computing device 14, the communication hub 44 may include device-side network components 50 configured to communicate with network signal stations 52 to enable a wireless communication network. For satellite-enabled communication, the communication hub 44 includes a Satellite Communications (SATCOM) module 54 that exchanges signals with satellites 56. For terrestrial-enabled communication, the communication hub includes a terrestrial communications module 58 configured to communicate with terrestrial access points 60. The terrestrial communications module 58 may be configured to communicate according to Long Term Evolution (LTE), Long Range (LoRa), or Television White Space (TVWS) standards, for example. Accordingly, the terrestrial access points may be respectively configured as cell towers, LoRa signal stations, or TVWS base stations. To determine whether to implement satellite-enabled communication or terrestrial-enabled communication, the communication hub 44 may further include a signal strength sensor 62. According to signal strength and conditions, the communication hub 44 is configured to switch between the SATCOM module 54 and the terrestrial communications module 58 via a signal switch module 64.
The device-side network components 50 and the network signal stations 52 are additionally included in a location determination subsystem 66 configured to determine a location of the tracking device 10 as it travels along the food commodity supply chain. The location determination subsystem 66 includes at least one of the SATCOM module 54 and the terrestrial communications module 58, and is configured to switch between the two modules 54, 58 according to the signal conditions determined by the signal strength sensor 62. The SATCOM module includes a Global Satellite Positioning (GPS) element configured to determine GPS coordinates of the tracking device 10. The location data 68 collected by the location determination subsystem 66 may be transmitted to the server computing device 14, along with the tracking device data 38, via a network 70 established by the device-side network components 50 and the network signal stations 52.
The server computing device 14 has at least one processor 18, which is configured to execute a sensor data analysis module 72. The sensor data analysis module 72 of the processor 18 is configured to receive the tracking device data 38 from the communication hub 44, including the environmental value of the environmental condition sensed by the sensor 30. The processor 18 then processes the environmental value to determine whether the environmental condition is within a predetermined environmental range. If the environmental condition falls outside the predetermined environmental range, i.e., falls above a maximum threshold or falls below a minimum threshold, the processor 18 is configured to transmit an alert 74 to the client computing device 16. The alert 74 is transmitted to the client computing device 16 via the network 70 and displayed via a user interface 76 on a display 78 of the client computing device 16. As discussed in detail below with reference to
Upon receiving the IMU values of the tracking device 10 included in the tracking device data 38, the processor 18 may also execute an IMU data analysis module 82 to process the IMU values to determine whether the IMU values are within a predetermined IMU range. As with the environmental condition, if the IMU values fall outside the predetermined IMU range, the processor 18 is configured to transmit the alert 74 to the client computing device 16.
As described above, the location data 68 collected by the location determination subsystem 66 may be transmitted to the server computing device 14 along with the tracking device data 38. Accordingly, the processor 18 may execute a location data analysis module 86 to determine a location 88 of the communication hub 44 that is associated with the tracking device 10. The location 88 of the communication hub 44 may be transmitted to the client computing device 16 and displayed on the user interface 76, as the suggested interventive action 80 may include be to moving the food commodity contained in the conveyance structure 26 from its current location 88 to a different location (i.e., out of storage), changing the position of the unit load 28 of the affected food commodity with respect to other unit loads, adjusting the environment of the transportation vehicle, and/or rerouting the unit load 28 of the food commodity to an alternate destination.
As shown in
The sensors 30 are configured to indicate changes in environmental conditions that could be detrimental to the quality and nutritional value of the food commodity as it travels along the supply chain. For example, the temperature sensor 30A may detect whether the temperature is too high or too low, which can impact the taste and texture of product, as well as cause spoilage of the product if it undergoes repeated heating and cooling cycles. Certain temperatures also increase the risk of microbial growth and contamination, such as E. coli and Salmonella in produce, which may lead to widespread recalls and large amounts of food waste. The humidity sensor 30B may detect changes in humidity of the environment of the food commodity, which may impact the quality and nutritional value of the product.
A gas sensor 30C can be used to measure levels of gases such as ethylene (C2H4), carbon dioxide (CO2), and volatile organic compounds (VOCs). Several types of fruits and vegetables produce C2H4 to initiate the ripening process. However, high levels of C2H4 may lead to premature ripening and damage to produce. Many fruits produce CO2 as they ripen, which slows the ripening process and may cause the fruit to fail to ripen properly. Additionally, high levels of CO2 may impact the flavor and texture of produce, leading to an undesirable product. Post-harvest ripening and/or sprouting, microbial contamination, and changes in environmental conditions may lead to alterations in the typical VOC profile of produce. As such, levels of VOCs may be used to indicate a quality or stress condition of produce.
Similar to the gas sensor 30C, the air quality sensor 30D can detect when air in the environment has an increased level of pollutants, such as smoke and fine particulate matter, as well as concentrations of ground level ozone, carbon monoxide, sulfur dioxide, and nitrogen dioxide, for example. Airborne pollutants may affect the quality of produce, as well as the health of consumers who ingest potentially dangerous chemicals deposited on the outside of produce products as a result of poor air quality.
The light sensor 30E can be used to determine whether a container that is configured to remain closed during transit was opened at any point. The light sensor 30E may additionally provide information regarding prolonged light or dark conditions of the conveyance structure 26 to which the tracking device 10 is mounted, which can have an impact on how quickly or slowly produce ripens.
Tracking device data 38, including data from the sensors 30 and the IMU module 32, as well as the identification of the tracking device 10, may be transmitted from the tracking device 10 to the communication hub 44 installed in the truck 90. As described in detail above, the communication hub may send the tracking device data 38 to the server computing device 14 for analysis.
In some implementations, conveyance structures 26 may be routed independently of each other based on the conditions experienced by each conveyance structure 26. For example, only a subset of (e.g., only one or a few of) conveyance structures 26 in a single vehicle load may experience environmental conditions that fall outside the predetermined environmental range, while the remaining conveyance structures 26 in the load do not. When this occurs, the affected conveyance structures 26 may be delivered to DEST2, as indicated by the dash-dot line, and the rest of the conveyance structures 26 on the truck 90 may continue on to DEST1 on a third route RT3. Additionally or alternatively, the affected conveyance structures 26 may be taken off the truck 90 at a central hub or storage facility, and placed on a different truck to be delivered to a closer location, such as DEST2, thereby resulting in a reconfigurable produce supply chain. The position of the affected conveyance structures 26 may be determined by the load on the respective pressure sensor 34, as well as identifying, via respective RFID tags 42, which tracking devices 10 sensed the outlying environmental conditions. Similarly, when a tracking device 10 mounted to a conveyance structure 26 at a storage facility or warehouse senses unfavorable environmental conditions for the unit load 28 of the food commodity, that conveyance structure may be tagged for expedited transit. In this manner, route planning decisions for each conveyance structure 26 may be made based on the environmental conditions experienced by that conveyance structure 26.
As described above with reference to
In the tracking system 200, location data 68 is collected by the location determination subsystem 66. However, the location data analysis module 286 is included in the processor 222 of the client computing device 16. As such, the location 88 of the communication hub 44 is determined at the client computing device 16 in the tracking system 200, and subsequently displayed on the user interface 76 via the display 78.
Continuing from step 302 to step 304, the method 300 may include including in the tracking device at least one sensor. The sensor may be configured to sense an environmental condition of the tracking device, and thus the food commodity, as it travels along the supply chain. The sensor may be configured as a temperature sensor, humidity sensor, gas sensor, air quality sensor, or light sensor, for example, and the tracking device may include more than one type of sensor.
Advancing from step 304 to step 306, the method 300 may include receiving, from the at least one sensor, the environmental value of the at least one environmental condition of the tracking device. At 308, the method may include processing the environmental value to determine whether the at least one environmental condition is within a predetermined range. Changes in conditions such as temperature, humidity, air quality, light, and exposure to gases can lead to changes in flavor or texture of the produce, as well as expedited ripening.
Continuing from step 308 to step 310, the method 300 may include, transmitting an alert when the at least one environmental condition falls outside the predetermined range. At 312, the method may include including in the alert a suggested interventive action based on the at least one environmental condition that falls outside the predetermined environmental range. As described above, the suggested interventive action may be to move the food commodity out of storage, change the position of the unit load of the affected food commodity with respect to other unit loads, adjusting the environment of the transportation vehicle, and/or reroute the food commodity during transit such that the quality and nutritional value of the food commodity is preserved and food loss is minimized.
The quality and freshness of food products is of high importance to consumers. When food products, especially perishable products such as produce, arrive at the marketplace in subpar conditions, these products may be priced and distributed differently than products that arrive at the peak of freshness. Additionally, a decline in quality of food products as they travel along the food commodity supply chain can lead to great quantities of food waste. The tracking systems 100, 200 and the method 300 described herein provide mechanisms for tracking the environmental conditions of food commodities as they move along the supply chain. This system enables the quality of the food commodities to be monitored at regular intervals, which permits users to take interventive actions that preserve the freshness of the food commodities and prevent spoilage and waste. Additionally, food commodities that are identified as having microbial contamination can be traced, such that the contaminated products and potential spread of the microorganism is contained. The system of the present disclosure utilizes compact tracking devices and communication systems that are low power, yet capable of transferring information that can be used to preserve the quality and nutritional value of food products as they travel along the food commodity supply chain. Such a technical solution is low cost, scalable, and provides environmental information about food commodities with sufficient accuracy to meet the needs of supply chain sustainability and accountability.

The tracking system may comprise a plurality of conveyance structures, a communication hub, and at least one computing device having at least one processor. Each conveyance structure may be configured to receive a unit load of a food commodity traveling along the food commodity supply chain, and each conveyance structure may have a respective tracking device mounted thereto. Each respective tracking device may include a sensor configured to track an environmental condition of an environment of the respective tracking device while the respective tracking device is traveling along the food commodity supply chain. The communication hub may be configured to receive and transmit data from each respective tracking device. The at least one processor may be configured to execute instructions using portions of associated memory to receive, from the communication hub, an environmental value of the environmental condition sensed by the sensor, process the environmental values to determine whether each of the environmental conditions is within a predetermined environmental range, and transmit an alert when one or more of the environmental conditions falls outside the predetermined environmental range. The alert may include a suggested interventive action based on the one or more environmental condition that falls outside the predetermined environmental range. The communication hub may include at least one of a SATCOM module and a terrestrial communications module. The communication hub may be configured to switch between the SATCOM module and the terrestrial communications module in accordance with signal conditions. In the absence of a network connection, the communication hub may store the data from each respective tracking device.
