For package delivery, a package locker system can be commonly used for residential apartments and/or single house communities in urban areas. In winter, these lockers may become frozen due to the snow and the freezing weather condition. This may cause the units in the lockers to become difficult or even impossible to open. As a result, a customer may not receive their package, and/or a delivery agent may not be able to utilize the locker system and deposit a package.
The detailed description is set forth with reference to the accompanying drawings. The use of the same reference numerals may indicate similar or identical items. Various embodiments may utilize elements and/or components other than those illustrated in the drawings, and some elements and/or components may not be present in various embodiments. Elements and/or components in the figures are not necessarily drawn to scale. Throughout this disclosure, depending on the context, singular and plural terminology may be used interchangeably.
The systems and methods disclosed herein are directed to a defrost solution for one or more package lockers under winter and other similar adverse conditions. An example locker system can implement defrost wires to thaw any ice around a door and lock area of a locker unit that receives a package. In some instances, a locker unit in a locker system may have independent wires, which may enable the locker unit to be defrosted individually. The locker system can include a controller configured to execute an automated preheat routine. For example, the controller can receive a signal from a delivery system (such as a drone, a robot, a vehicle, a smart device, etc.) that causes the controller to activate a heating element a predetermined time (e.g., ten minutes or the like) before a delivery robot or delivery vehicle arrives at the locker system. Similarly, a person who receives the package can also request the defrost before pickup. A smart locker network can be used to share information about a frozen condition to other units in the same area.
Turning now to the drawings,
The delivery unit 102 can include any delivery device such as a robot or other autonomous vehicle such as an unmanned aerial vehicle. The delivery unit 102 can also include a connected vehicle that is driven by a human. Also, the delivery unit 102 can also include a non-connected vehicle that is driven by a human who is equipped with a smart device, such as a smartphone or tablet. The delivery unit 102 can include a means for communicating over the network 108.
The locker system 104 can comprise one or more locker units, such as locker unit 110. In some instances, the locker system 104 includes a plurality of locker units such as is common in apartment complexes or commercial buildings that service many tenants. The locker system 104 can also comprise a locker system controller 112. The locker system controller 112 can comprise a processor 114, memory 116, an optional display 118, and a communications interface 120 for accessing the network 108. Also, the locker system 104 can be coupled to a power or electrical source to provide electricity to the components of the locker system 104.
In general, the processor 114 executes instructions stored in memory 116 to perform any of the locker maintenance features disclosed herein, such as locker defrosting. It will be understood that when referring to actions performed by the locker system controller 112, this includes the execution of instructions by the processor 114.
Each of the individual locker units, such as locker unit 110, can include a unit controller 122, a door 124, a lock 126, and a defrosting assembly 128. The locker unit 110 is configured to receive and retain a package and can have any defined size. The door 124 can be actuated to allow for opening and closing. For example, the door 124 may be attached via a hinge or the like. The lock 126 can secure the door 124. In some instances, the lock 126 can be manually actuated using a key. Alternatively, the lock 126 can include a smart-lock that can be actuated electronically.
In general, the unit controller 122 can comprise a processor 130 that executes instructions stored in memory 132 to perform any of the locker maintenance features disclosed herein, such as locker defrosting. It will be understood that when referring to actions performed by the unit controller 122, this includes the execution of instructions by the processor 130. In some instances, the unit controller 122 may not be present.
The defrosting assembly 128 can include a first defrosting element 134 that is associated with the door 124 and a second defrosting element 136 that is associated with the lock 126. For example, the first defrosting element 134 can include a defrosting wire that heats when an electrical current is applied by the unit controller 122. The first defrosting element 134 can extend around a peripheral edge of the door 124. The second defrosting element 136 can also include a defrosting wire that encircles the lock 126. In some instances, a third defrosting element 138 can extend around an outer-peripheral geometry of the locker unit 110. Thus, the interfacing surfaces or edges of the locker unit 110 and the door 124 can be independently heated.
Referring back to the locker system controller 112, the locker system controller 112 can be configured to orchestrate operations of the individual locker units. For example, the locker system controller 112 can communicate with the service provider 106 to obtain weather related information. This can include ambient weather information for a region that includes the locker system 104.
The locker system controller 112 can receive weather information from the service provider 106 and perform predictive analytics on the same to determine when a frozen condition may be present with respect to the locker units. The frozen condition can indicate that the locker unit is likely to be in a frozen condition or that ambient weather conditions around the locker system have increased a likelihood that the locker unit is frozen.
In one example, assume that the weather information is indicative of a recent snow or ice storm. Also, subsequent to the storm the weather information indicates that the temperature around the locker system 104 may reach melting temperature. This may result in the snow melting and water may leak into and/or around the locker units. If the temperature drops below freezing in the evening, at night, or early morning, the locker units may freeze if water is present. In these instances, the locker system controller 112 can detect that water is likely to be present and may freeze. Thus, the locker system controller 112 can automatically defrost a locker unit when the locker system controller 112 receives an indication from the delivery unit 102 that a package is being delivered within a specified period of time. For example, the delivery unit 102 may transmit a signal to the locker system controller 112 that indicates that the delivery unit 102 may be delivering a package to a locker unit within a specified time frame, such as ten minutes. Upon receiving this signal, the locker system controller 112 can pre-defrost the locker unit before delivery unit 102 arrival.
For example, the locker system controller 112 may learn over time that many tenants pick up their mail after 5 pm, the locker system controller 112 can choose to defrost all units at a time before 5 pm. The specified time frame can vary according to locker design. The locker system controller 112 can be configured to learn and adapt to the behavior of how individual locker units are used and utilize this type of historical data to select when locker units may be defrosted.
In another example, the locker system controller 112 may choose to defrost all or a portion of the units based only on the prediction and/or detection of ice. Also, during a potential water condition such as rain or freezing rain, the locker system controller 112 may determine when the ambient temperature has dropped below freezing and that water is likely present. The locker system controller 112 may detect an actual or potential frozen condition and execute locker unit defrosting in response. The locker system controller 112 may also sense or predict a potential water condition where evaporating condensation can be estimated based on detection ambient temperature and measurement time. In sum, the locker system controller 112 can infer or predict a frozen condition of a locker unit based on a weather pattern. A weather pattern may be determined from past, current, and/or future weather conditions. Thus, one example pattern includes determining snow or ice conditions followed by thawing conditions, which are followed by freezing temperatures. Another example includes evaporative conditions followed by freezing temperatures. Generally, any conditions that may lead to exposure of a locker unit to liquid water followed by freezing temperatures may trigger an inference that the locker unit is frozen. In some instances, the locker unit 104 can include a moisture sensor 142 that detects presence of moisture inside or on a surface of the locker unit 104.
In yet another example, a user of the locker system 104 can utilize the display 118 to defrost an individual locker unit if the locker unit is frozen. That is, the display 118 can function as a human-machine interface. The user can interact with the locker system 104 using graphical user interfaces presented on the display 118. Further, if a user selects to have a locker unit defrosted, the locker system controller 112 can be configured to execute a defrosting of other locker units positioned around the identified locker unit, or in some instances all locker units. The user can also use their smart device, such as a Smartphone to transmit information to the locker system controller 112. For example, a user can transmit a signal to the locker system controller 112 that indicates that their locker unit is frozen. Additionally, a delivery unit such as a drone or robot can also transmit a similar signal to the locker system controller 112 if the drone or robot attempts to open the locker unit and it appears to be in a frozen condition.
It will be understood that while the prior examples involved the use of the locker system controller 112 to orchestrate defrosting features for individual locker units, each of the locker units can be individually configured to provide the same functions independently from one another. In some instances, when the locker system controller 112 detects or predicts a frozen condition, the locker system controller 112 can transmit this frozen condition to other smart lockers or the service provider 106. For example, the locker system controller 112 can transmit a frozen condition signal to another locker system 140 located remotely. The locker system controller 112 can also route the frozen condition signal to the locker system 140 through the service provider 106.
Next, the method can include a step 204 of determining a frozen condition for the locker unit. The frozen condition can be determined or inferred in various ways. For example, a unit controller (of an individual locker unit) or a locker system controller (a system with a plurality of locker units) can receive an indication that the locker unit is frozen from a human-machine interface associated with the locker unit. In another example, the frozen condition can be determined using weather information. An example method of determining a frozen condition from weather information is provided in
The method can also include a step 206 of activating a defroster element associated with the locker unit before delivery of the package by the delivery unit according to expected delivery time. To be sure, in some instances, step 204 may be eliminated. That is, the step of activating a defroster element can be based only on receiving the message from the delivery unit that a package is about to be delivered. As noted above, the message can indicate that an estimated time of delivery is within fifteen minutes. The controller can activate the defroster of the locker unit when the message is received or within another predetermined period of time. For example, the controller can activate the defroster when it is within ten minutes of the estimated time of delivery. To be sure, other time frames can be used and may be based on design requirements, such as how long it may take to defrost the door and/or a lock of the locker unit.
In some instances, the method can include a step 208 of transmitting the frozen condition to another locker system or a service provider. Thus, a frozen condition of a locker system can be relayed to other locker systems that may or may not have weather analysis capabilities. Also, the control capabilities of the locker system can be decentralized and maintained within a cloud environment or another on-premise computing system. For example, in an apartment complex, some functionalities can be managed from a server. The server can analyze weather data and/or package delivery messages and disseminate defrost requests to locker systems and/or individual locker units.
