The present disclosure relates to communications methods and utility meters.
Customers of an electric utility often contact their electric utility to report and check the status of outages. Some reported outages, however, are not actually outages. As a result, the electric utility may deploy a utility truck and then discover that deployment of the utility truck is unnecessary to address a reported issue. For example, a customer may report an outage despite only needing to flip a breaker. Unnecessary utility truck deployments may be time-consuming and costly for the electric utility, and may be a negative customer experience for customers.
A method of operating an electronic device to communicate with an electric utility meter or a transformer, according to some embodiments herein, may include transmitting, via a cellular network and/or an unlicensed frequency band of a wireless mesh network, a ping from the electronic device to the electric utility meter or the transformer. The method may include receiving, via the cellular network and/or the unlicensed frequency band of the wireless mesh network, meter data from the electric utility meter or the transformer at the electronic device, in response to the ping. Moreover, the method may include displaying, via a Graphical User Interface (GUI) of the electronic device, an indication of a voltage measured by the electric utility meter, in response to receiving the meter data.
In some embodiments, displaying the indication of the voltage may include displaying an indication that the voltage is present on a customer side of the electric utility meter. Additionally or alternatively, displaying the indication of the voltage may include displaying a numerical value of an average voltage measured by the electric utility meter.
According to some embodiments, the method may include receiving, via the GUI, a first user input including a meter identifier of the electric utility meter or a transformer identifier of the transformer. Transmitting the ping may be performed in response to a second user input that is received via the GUI after receiving the first user input. In some embodiments, the first and second user inputs may be user inputs to a website that is behind a firewall of an electric utility. Moreover, the method may include accessing the website via a custom web browser of the electric utility. Additionally or alternatively, the method may include receiving, via the GUI, a third user input to re-ping the electric utility meter or to delete the electric utility meter from a list of pinged electric utility meters, after displaying the indication of the voltage. The list of the pinged electric utility meters may include respective indications of average voltage measured by the pinged electric utility meters.
In some embodiments, transmitting the ping and receiving the meter data may be performed concurrently with a telephone or web-based communication session between a user of the electronic device and an electric utility customer who is associated with the electric utility meter. Additionally or alternatively, the unlicensed frequency band of the wireless mesh network may include 900 Megahertz (MHz).
According to some embodiments, the electric utility meter may be an Advanced Metering Infrastructure (AMI) meter. Moreover, the method may include displaying, via the GUI, an indication of an error in response to a user input, via the GUI, that includes: an invalid meter number; or a meter number of a non-AMI meter.
In some embodiments, the meter data may include real-time data including: an instantaneous voltage measured by the electric utility meter; instantaneous power delivered to a customer premise that is connected to the electric utility meter; instantaneous power received from the customer premise; accumulated power delivered to the customer premise; and accumulated power received from the customer premise. Moreover, the method may include displaying, via the GUI, the real-time data, in response to a user input after displaying the indication of the voltage.
According to some embodiments, the method may include displaying, via the GUI, an indication of a connection status of a switch of the electric utility meter. Moreover, the method may include transmitting, via the cellular network and/or the unlicensed frequency band of the wireless mesh network, a command that remotely controls the switch to connect or disconnect the electric utility meter, in response to a user input via the GUI.
In some embodiments, the method may include receiving, via the cellular network and/or the unlicensed frequency band of the wireless mesh network, an unsolicited indication from another electric utility meter that the other electric utility meter is experiencing a power outage. Additionally or alternatively, transmitting the ping may include transmitting the ping via a Local Area Network (LAN) of an electric utility to the cellular network or the wireless mesh network, and receiving the meter data may include receiving the meter data via the LAN from the cellular network or the wireless mesh network.
According to some embodiments, transmitting the ping may include: transmitting, via the cellular network, the ping from the electronic device to a gateway device that is in the field; then transmitting, via the unlicensed frequency band, the ping from the gateway device to the electric utility meter or the transformer. Moreover receiving the meter data may include: receiving, via the unlicensed frequency band, the meter data from the electric utility meter or the transformer at the gateway device; then receiving, via the cellular network, the meter data from the gateway device at the electronic device.
An electronic device, according to some embodiments herein, may include a display screen, a network interface, and a processor. Moreover, the electronic device may include a storage medium coupled to the processor and including computer readable program code that when executed by the processor causes the processor to perform operations including transmitting, via a cellular network and/or an unlicensed frequency band of a wireless mesh network, a ping from the electronic device to an electric utility meter or a transformer. The operations may include receiving, via the cellular network and/or the unlicensed frequency band of the wireless mesh network, meter data from the electric utility meter or the transformer at the electronic device, in response to the ping. Moreover, the operations may include displaying, via the display screen, an indication of a voltage measured by the electric utility meter, in response to receiving the meter data.
In some embodiments, the network interface may be configured to connect the electronic device to a LAN of an electric utility. Moreover, transmitting the ping may include using the network interface to transmit the ping via the LAN to the cellular network or the wireless mesh network, and receiving the meter data may include using the network interface to receive the meter data via the LAN from the cellular network or the wireless mesh network.
A computer program product, according to some embodiments herein, may include a non-transitory computer readable storage medium including computer readable program code therein that when executed by a processor causes the processor to perform operations including transmitting, via a cellular network and/or an unlicensed frequency band of a wireless mesh network, a ping from an electronic device to an electric utility meter or a transformer. The operations may include receiving, via the cellular network and/or the unlicensed frequency band of the wireless mesh network, meter data from the electric utility meter or the transformer at the electronic device, in response to the ping. Moreover, the operations may include displaying, via a GUI of the electronic device, an indication of an electrical parameter measured by the electric utility meter, in response to receiving the meter data.
In some embodiments, displaying the indication of the electrical parameter may include: displaying an indication that a voltage is present on a customer side of the electric utility meter; and/or displaying a numerical value of an average voltage measured by the electric utility meter.
Pursuant to embodiments of the present inventive concepts, methods of operating an electronic device to communicate with an electric utility meter are provided. Conventional operations of pinging the meter to receive a binary response may provide insufficient data to troubleshoot a reported customer problem. Moreover, some conventional meter ping operations are too slow to provide efficient customer support. The methods of the present inventive concepts, however, may be used to rapidly obtain various data from the meter to enable an electric utility to remotely troubleshoot a reported customer problem before deploying a utility truck. For example, the data may include a meter read, connection status, an instantaneous voltage, an average voltage, delivered power usage, and/or received power usage.
As an example, a meter may be receiving low-voltage power, which may result in a customer experiencing flickering lights, the customer's lights being dim, or the customer's appliance (e.g., a clothes dryer) not functioning properly. Merely pinging the meter to receive a binary response, such as “yes” or “no,” may not identify the low voltage, and thus may result in unnecessarily sending a utility truck to the customer. The methods of the present inventive concepts, however, may rapidly provide voltage data that the electric utility can use to identify the low voltage and better assess and correct the situation.
Example embodiments of the present inventive concepts will be described in greater detail with reference to the attached figures.
The meter 110 may be configured to interface with one or more distributed energy resources DER at the customer premise 120. For example, the meter 110 may be configured to interface with a solar photovoltaic (PV) system, a fuel cell, an energy storage system, or an Electric Vehicle (EV) charging station.
The meter 110 may provide electricity from an electric grid 100 to at least one Alternating Current (AC) load A that is at the customer premise 120, and may measure electricity usage at the customer premise 120. For example, the AC load(s) A may include at least one appliance that may be powered by the electric grid 100 through the meter 110. An appliance may be a refrigerator, dishwasher, laundry machine, oven, or any other large machine that uses electricity to perform, for example, cooking, cleaning, or food preservation functions in a household, institutional, commercial, or industrial setting.
Additionally or alternatively to appliances, the AC load(s) A may include various devices that use electricity and are connected to the meter 110. For example, consumer electronics and heating/cooling devices and/or systems may be at the customer premise 120. Moreover, in some embodiments, the customer premise 120 may be a billboard, and the electric grid 100 may provide power for lights or an electronic display of the billboard.
The meter 110 is downstream from an electric utility substation 140 that serves the customer premise 120. The substation 140 may include one or more transformers. Between the substation 140 and the meter 110 is a distribution transformer DT, which may control a voltage level of power that is transmitted to the meter 110. In particular, the distribution transformer DT serves the customer premise 120 and may be the closest transformer of the electric grid 100 to the customer premise 120. The distribution transformer DT may be underground, mounted on a concrete pad, mounted on a utility pole, or otherwise fixed at a location that is upstream and spaced apart from the meter 110.
A single distribution transformer DT may provide power to one or more customers in a given area. For example, in an urban area, a plurality of homes may be fed off of a single distribution transformer DT. Rural distribution, on the other hand, may use one distribution transformer DT per customer. Moreover, a large commercial or industrial complex may rely on multiple distribution transformers DT.
A distribution transformer DT has a low-voltage secondary (e.g., output) side that distributes power to one or more customers. For example, in the United States, the low-voltage secondary side of the distribution transformer DT may be configured for a 240/120-Volt system, and three wires (including one neutral wire) may be fed from the low-voltage secondary side to the meter 110.
The meter 110 (or the distribution transformer DT) may be communicatively coupled to an office/data center 130 of an electric utility via a communication network 115. For example, the communication network 115 may comprise a wireless network, such as a cellular (e.g., 3G/4G/5G/LTE, other cellular) network and/or a wireless mesh network. Accordingly, the meter 110 (or the distribution transformer DT) may communicate wirelessly with the office/data center 130, which may comprise a head end H of the electric utility, via the communication network 115. Additionally or alternatively, the meter 110 (or the distribution transformer DT) may communicate wirelessly, via the communication network 115, with a handheld portable electronic device 102 that is in the field (
One example of the room 134 is a control room, such as a Distribution Control Center (DCC), in which one or more users 101 may use the present inventive concepts for support in closing outage tickets and reducing truck rolls/deployment. Another example of the room 134 is a customer care center, in which one or more users 101 may use the present inventive concepts to support customer outage phone calls or power quality phone calls. For example, the customer care center may be a call center in which a plurality of users 101 are taking telephone calls from customers.
In some embodiments, a plurality of gateway devices 195 can be used in the field to collect data from a mesh network comprising electric utility meters 110 (
The processor P may be coupled to the network interface(s) N. The processor P may be configured to communicate with one or more electric utility meters 110 via the wireless network interface(s) N. For example, the network interface(s) N may include short-range wireless communications circuitry, such as Wi-Fi circuitry and/or BLUETOOTH® circuitry. Additionally or alternatively, the network interface(s) N may include cellular communication circuitry that provides a cellular wireless interface (e.g., 4G/5G/LTE, other cellular) and/or circuitry that provides a wireless mesh network interface. In some embodiments, the electronic device 102 may be a handheld portable electronic device that may be held by the user 101. Alternatively, the electronic device 102 may be a desktop computer or laptop computer. The network interface(s) N may include a wired and/or wireless network interface such as a wired and/or wireless LAN (e.g., Ethernet/Wi-Fi) interface by which the electronic device 102 may be configured to connect to a LAN of an electric utility, such as the LAN 135 (
In some embodiments, the meter 110 may be a smart meter, such as a single-phase or poly-phase Advanced Metering Infrastructure (AMI) meter. Accordingly, similar to the electronic device 102 of
As shown in
The electronic device 102 may receive (Block 320), via/using the cellular network and/or the unlicensed frequency band of the wireless mesh network, meter data from the meter 110 (or the transformer), in response to the ping. As an example, the meter data may be received from the meter 110 (or the transformer) at the gateway device 195 via the unlicensed frequency band, and then received from the gateway device 195 at the electronic device 102 via the cellular communications link. The unlicensed frequency band may comprise 900 MHz. In some embodiments, the transmit (Block 310) and receive (Block 320) operations may be performed via the same medium/network, such as the same cellular network or the same wireless mesh network.
Moreover, the electronic device 102 may display (Block 330), via a GUI of the electronic device 102, an indication of an electrical parameter (e.g., a voltage) measured by the meter 110, in response to receiving (Block 320) the meter data. For example, the GUI may be displayed on a display screen DS (
The cellular/mesh network may communicate the ping and the meter data relatively quickly. For example, the electronic device 102 may receive (Block 320) the meter data within 9-60 seconds of transmitting (Block 310) the ping. In comparison with such fast communications, some conventional techniques have may take 30-45 minutes, which may be too slow to efficiently provide real-time assistance to an electric utility customer. Moreover, conventional responses to pings may be not only slow but also simple binary responses, whereas the meter data received (Block 320) in

The first and second user inputs may, in some embodiments, be user inputs to a website that is behind a firewall of an electric utility. This may protect against unauthorized use of the website to communicate with the meter 110 (or the transformer). Additionally or alternatively, operation(s) of accessing (Block 300) the website/application may include entry of a user name and password into the website/application before enabling the user 101 to transmit (Block 310) the ping, thus enhancing security. Moreover, in some embodiments, operation(s) of accessing (Block 300) the website/application may include accessing a website via a custom web browser of an electric utility. For example, use of the website/application may require that the user 101 (a) is using a particular browser, such as the custom web browser of the electric utility, on a smartphone (e.g., the electronic device 102) that is issued by the electric utility or (b) is on a network, such as the LAN 135 (
One or more operations of receiving (Block 305) user input(s) may be performed after operation(s) of displaying (Block 330) an indication of an electrical parameter measured by the meter 110. For example,
Before or after receiving (Block 320) the meter data and displaying (Block 330) the indication of the electrical parameter, a user 101 of the electronic device 102 may transmit (Block 310) a ping to another meter 110 (or another transformer). As an example, the user 101 may provide another meter number as a user input (Block 305) while awaiting the results of a ping. In some embodiments, a group of meter numbers may be simultaneously provided as user input(s) (Block 305) at the electronic device 102, which may result in simultaneously transmitting (Block 310) a plurality of pings to a plurality of meters 110 (or a plurality of transformers), respectively. This may be beneficial during, for example, storm clean-up to verify power restoration to a group of customer premises 120 (

Moreover, the line side data 412 may indicate a numerical average voltage measured by the meter 110 over a given timeframe (e.g., 5 minutes), as well as minimum and maximum voltages during that timeframe. In some embodiments, the GUI 400 may also display a list 440 of features that the user 101 may select via the GUI 400. For example, the user 101 can select the item “Phase Angle Data” from the list 440 to receive information about how to use the GUI 400 to display phase angle data. Additionally or alternatively, the GUI 400 may include one or more information icons, such as a load side information icon 414-I, which the user 101 can select to receive additional information and a description of a measurement result.
In some embodiments, the GUI 400 may include a meter list 420 that indicates meters 110 that the user 101 has pinged. The user 101 can select a clear page button 421 to clear the list 420, which list 420 may indicate average voltages for respective meters 110 that have been pinged. The user 101 can also select an action button 422 for an individual meter 110 on the list 420. Actions available to the user 101 may include deleting the individual meter 110 from the list 420 or re-pinging the individual meter 110.

In some embodiments, the user 101 may access customer account data via the GUI 400. For example, after typing a meter number in the text box 410, the GUI 400 may automatically display customer account data for a customer whose meter 110 is associated with the meter number. Alternatively, the GUI 400 may present the user 101 with a user-selectable option to view the customer account data in response to entry by the user 101 of the meter number in the text box 410. The customer account data may include, for example, a customer's name, mailing address, phone number, email address, and/or account payment status (e.g., current or delinquent).

In some embodiments, the account details may be displayed after pinging a meter 110. Accordingly, the GUI 400 may simultaneously display the account details along with a meter number and a last read time/date of the meter 110. The last read time/date indicates the most recent time/date that the meter 110 was read into/by a meter database.
Upon quickly resolving an issue with respect to the meter 110, the user 101 can select an avoid-outage-ticket button 419 via the GUI 400 to indicate that the issue was resolved without creating an outage ticket. The GUI 400 thereby allows the user 101 to report the avoidance of outage tickets.

The user 101 may be an electric utility employee or contractor who is authorized to access data from meters 110 and transformers. Alternatively, the user 101 may be a customer of the electric utility. For example, though the customer may not be authorized to access transformer data or data regarding other customers' meters 110, the customer may, in some embodiments, be authorized to use the GUI 400 to ping the customer's meter 110.
Methods of operating an electronic device 102 according to embodiments of the present inventive concepts may provide a number of advantages. These advantages include significantly faster response times to pings of meters 110. For example, the use of a fast, reliable cellular network (e.g., 4G, 5G, LTE, other fast cellular) or RF mesh network may facilitate rapid response times. Moreover, the rapid response times may facilitate the receipt of a wide range of data, including real-time data, from the meter 110 at the electronic device 102.
The electronic device 102 may perform any of the operations of
The advantages of the present inventive concepts may also include an improved customer experience. For example, a customer may report an outage without knowing that the issue is simply a matter of a flipped/tripped breaker. Conventionally, a utility truck may be sent to the customer, which may take hours of time. Using the present inventive concepts, however, an electric utility can ping the meter 110 and identify that the customer has positive voltage, and thus that the meter 110 has power. Accordingly, the electric utility can remotely notify the customer to flip the breaker to solve the problem, thus solving the problem in minutes rather than hours.
The present inventive concepts have been described above with reference to the accompanying drawings. The present inventive concepts are not limited to the illustrated embodiments. Rather, these embodiments are intended to fully and completely disclose the present inventive concepts to those skilled in this art. In the drawings, like numbers refer to like elements throughout. Thicknesses and dimensions of some components may be exaggerated for clarity.
Spatially relative terms, such as “under,” “below,” “lower,” “over,” “upper,” “top,” “bottom,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “under” or “beneath” other elements or features would then be oriented “over” the other elements or features. Thus, the example term “under” can encompass both an orientation of over and under. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
Herein, the terms “attached,” “connected,” “interconnected,” “contacting,” “mounted,” and the like can mean either direct or indirect attachment or contact between elements, unless stated otherwise.
Well-known functions or constructions may not be described in detail for brevity and/or clarity. As used herein the expression “and/or” includes any and all combinations of one or more of the associated listed items.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present inventive concepts. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises,” “comprising,” “includes,” and/or “including” when used in this specification, specify the presence of stated features, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, operations, elements, components, and/or groups thereof.
It will also be understood that although the terms “first” and “second” may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. Thus, a first element could be termed a second element, and similarly, a second element may be termed a first element without departing from the teachings of present inventive concepts.
Example embodiments of the present inventive concepts may be embodied as nodes, devices, apparatuses, and methods. Accordingly, example embodiments of present inventive concepts may be embodied in hardware and/or in software (including firmware, resident software, micro-code, etc.). Furthermore, example embodiments of present inventive concepts may take the form of a computer program product comprising a non-transitory computer-usable or computer-readable storage medium having computer-usable or computer-readable program code embodied in the medium for use by or in connection with an instruction execution system. In the context of this document, a computer-usable or computer-readable medium may be any medium that can contain, store, communicate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device.
The computer-usable or computer-readable medium may be, for example but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device. More specific examples (a nonexhaustive list) of the computer-readable medium would include the following: an electrical connection having one or more wires, a portable computer diskette, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), an optical fiber, and a portable compact disc read-only memory (CD-ROM). Note that the computer-usable or computer-readable medium could even be paper or another suitable medium upon which the program is printed, as the program can be electronically captured, via, for instance, optical scanning of the paper or other medium, then compiled, interpreted, or otherwise processed in a suitable manner, if necessary, and then stored in a computer memory.
Example embodiments of present inventive concepts are described herein with reference to flowchart and/or block diagram illustrations. It will be understood that each block of the flowchart and/or block diagram illustrations, and combinations of blocks in the flowchart and/or block diagram illustrations, may be implemented by computer program instructions and/or hardware operations. These computer program instructions may be provided to a processor of a general purpose computer, a special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create/use circuits for implementing the functions specified in the flowchart and/or block diagram block or blocks.
These computer program instructions may also be stored in a computer usable or computer-readable memory that may direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer usable or computer-readable memory produce an article of manufacture including instructions that implement the functions specified in the flowchart and/or block diagram block or blocks.
The computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions that execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart and/or block diagram block or blocks.
