This application claims priority to commonly owned U.S. Provisional Patent Application No. 60/592,053, also entitled “Mapping in Mobile Data Collection Systems, Such as for Utility Meter Reading and Related Applications,” filed Jul. 28, 2004, which is herein incorporated by reference.
Utility companies typically rely on meter reading to determine consumption of a utility by its customers. In some utility meter reading applications, operators drive vehicles equipped with radio-equipped data collection units around an area or route to read electric, gas, and/or water meters. The meters are equipped with modules that allow them to send and receive signals. This style of meter reading, sometimes referred to as mobile automatic meter reading (MAMR), allows meter reading to be completed without direct access to the meter.
MAMR is sometimes used in saturated areas where there may be large populations of meters, difficult-to-access meters, or hazardous-to-read meters.
When used in such areas, MAMR can dramatically improve meter reading efficiency. For example, a single data command unit transceiver reads an average of 10,000-12,000 meters in an eight-hour shift, and can read up to 24,000 meters per day, depending on meter density and system use.
Routes for MAMR are typically defined geographically and may include hundreds or thousands of meters. The meters on the route are read using one or more techniques. For example, with a wake-up technique, a MAMR vehicle moves through an area and sends wakeup signals to notify the meters in the area to send meter reading data. With a bubble-up technique, the MAMR vehicle simply picks up broadcasted signals from all meters in its vicinity. To determine the endpoints in a route, MAMR systems typically rely on route information provided by the utility. In some cases, the route information includes a list that identifies each meter using a unique meter ID and address assigned to the meter. The route information is typically formulated in advance of driving the route, and is often based on the geographic location of each meter relative to other meters in the route. For example, a MAMR route may have starting and ending points, and meters are read according to proximity from a vehicle moving between the starting and ending points.
Routes consisting of lists of meter addresses are typically provided in advance of MAMR activities. Because of this, and because of many other reasons, route planners, MAMR operators, utilities, and their customers could benefit from improvements in monitoring and mapping capabilities in MAMR systems.
In the drawings, the same reference numbers identify identical or substantially similar elements or acts. To facilitate the discussion of any particular element or act, the most significant digit or digits in a reference number refer to the figure number in which that element is first introduced (e.g., element 204 is first introduced and discussed with respect to
A portion of this disclosure contains material to which a claim for copyright is made. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or patent disclosure (including Figures), as it appears in the Patent and Trademark Office patent file or records, but reserves all other copyright rights whatsoever.
The invention will now be described with respect to various embodiments. The following description provides specific details for a thorough understanding of, and enabling description for, these embodiments of the invention. However, one skilled in the art will understand that the invention may be practiced without these details. In other instances, well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments of the invention.
It is intended that the terminology used in the description presented be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific embodiments of the invention. Certain terms may even be emphasized below; however, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this Detailed Description section.
The method and system described herein allows for monitoring and management of mobile automatic meter reading (MAMR) activities via out of route meter read identification and graphical route playback. In some embodiments, some of the monitoring and management activities occur at a mobile data collection system. The mobile data collection system may include a combination of components (including both hardware and software) that generally facilitate the collection of meter data from utility meters (e.g., electric, gas, water, etc.) and the graphical display of meter routes in progress via the use of maps or other features.
In some embodiments, the mobile data collection system may be configured to identify and record information relating to out of route meters (e.g., meters not associated with a route presently known by the mobile data collection system). Such meters (or “endpoints”) may be unexpectedly, inadvertently, unintentionally, or otherwise, encountered during a meter reading route. In the event of an out of route endpoint, the mobile data collection system may alert an operator of the mobile data collection system. For example, the mobile data collection system may display information relating to each of the out of route endpoints on the route and/or may provide an audible alert when such a meter is encountered.
Information relating to the reading of out of route endpoints on the route may include the physical location of each of the encountered out of route endpoints and the physical location of the vehicle at the time the endpoint was read. The same information may be provided for in route endpoints. The mobile data collection system may provide this information to the operator using a map and/or in another formats, such as in text on a list or other display. While driving the route, the operator may use the information relating to the out of route endpoints to make decisions about how to drive the route. In some embodiments, the mobile data collection system may automatically determine an optimized driving path for the operator based on the collected out of route endpoint information. The automatic determination of an optimized driving path may be based on mathematical computations and algorithms applied to the collected information, including information about the route, the vehicle, the endpoints, etc.
In addition, the mobile data collection system may provide information relating to the out of route endpoints to a host processing system, or any other system configured for further processing of the information. The utility service provider may then use this information to reconfigure or optimize meter reading routes and to otherwise increase the efficiency of the mobile collection system. For example, the information related to out of route meters may be used to automatically determine which endpoints to include within predetermined routes, thus reducing the number of out of route endpoints encountered on each route. Information about out of route endpoints may also be of use when a utility is managing the billing of off cycle reads, which are often associated with customers that are moving.
The mobile data collection system may also log route data so that it can be played back after the route is completed. For example, the mobile data collection system may provide a map showing the path that the vehicle took during the route, the order that the meters were read, the timing of the route, etc. The type of information displayed on the map may include the location of the vehicles, the reading of meters or groups of meters, the identification of in route and out of route meters, etc. This information may be used for almost any purpose, including training, supervision of employees, improving route efficiency, assisting contractors or substitute meter readers, route optimization, etc.
Aspects of the invention can be embodied in a special purpose computer or data processor that is specifically programmed, configured, or constructed to perform one or more of the computer-executable instructions explained in detail herein. Aspects of the invention can also be practiced in distributed computing environments where tasks or modules are performed by remote processing devices, which are linked through a communication network. In a distributed computing environment, program modules may be located in both local and remote memory storage devices.
Aspects of the invention may be stored or distributed on computer-readable media, including magnetically or optically readable computer disks, as microcode on semiconductor memory, nanotechnology memory, organic or optical memory, or other portable data storage media. Indeed, computer-implemented instructions, data structures, screen displays, and other data under aspects of the invention may be distributed over the Internet or over other networks (including wireless networks), on a propagated signal on a propagation medium (e.g., an electromagnetic wave(s), a sound wave, etc.) over a period of time, or may be provided on any analog or digital network (packet switched, circuit switched, or other scheme). Those skilled in the relevant art will recognize that portions of the invention reside on a server computer, while corresponding portions reside on a client computer, such as a mobile device.
While not illustrated in detail, each meter (102, 104, or 106) includes a storage component (not shown) for storing collected data before transmission to a data collection system. The storage component may also store information identifying the meter, such as a meter address. In addition, each meter may be configured with a receiver/transmitter telemetry device (e.g., ERT) capable of sending and receiving signals to and from a mobile data collection system 108. In general, these components (meter, storage, and telemetry device) may be collectively referred to as an “endpoint.” However, the term “endpoint” may herein refer to any one of a number of possible configurations for locally collecting data, such as utility consumption data, and not only the sample configuration described above.
In some embodiments, the mobile data collection system 108 may send a wake-up signal to an endpoint. The received wake-up signal prompts the endpoint to transmit meter reading data to the mobile data collection system 108. In alternative embodiments, “bubble-up” (broadcast) techniques may be used instead of the “wake-up” technique described above. In yet other embodiments, the mobile data collection system 108 may be capable of point-to-point communications with specific endpoints.
To facilitate MAMR or similar techniques, the mobile data collection system 108 may be installed in a vehicle 109 or be otherwise configured to be transported through a route. For example, the vehicle may include the appropriate antennas, power cables, mounts, etc.
The system 100 also includes a host processing system and meter reading application(s) 110 for processing collected meter reading data. The host processing system and meter reading application(s) 110 may be operating in association with systems operated by a utility company, such as a utility billing system 112 or, more generally, a customer information system (CIS). In this way, the host processing system and meter reading application 110 can also be used to communicate data to the data collection system 108. This information may include standard route data. In general, the meter reading application uses customer information downloaded, for example, to create a route file used when driving the route to collect meter data. The collected data is returned to the meter reading application for processing. Examples of meter reading applications may include MV-RS™, Premierplus4™, Viena™, and Integrator™, all by Itron, Inc. of Spokane, Wash.
A processor 206 and memory or other data storage 208 provide capabilities to control several processes, including management of collected meter reading data and processing of input for purposes of determining an efficient route for meter reading. For example, the memory 208 can store not only collected meter data, but also route and other information. A CD ROM 209 may handle removable media in the mobile data collection system 108. A user input/output component 210 provides an appropriate user interface for an operator of the data collection system 108. For example, the mobile data collection system 108 may provide a color touch screen display for ease of use and clear graphical mapping displays. Other user input/output options may be used including mouses, microphones, speakers, joysticks, keyboards, LCD screens, audio, etc.
One application of the input/output component 210 includes displaying and controlling mapping images generated by a mapping component 212. In this way, the operator is provided with feedback, so that he or she can determine which meter readings have been completed on a particular route and so he or she can view meters on the route in relation to the vehicle and to other meters. The mapping component 212 may interface with the mobile collector applications component 204.
Any one of the components described above may be contained on notebook computer or other device that can be easily removed from the vehicle when not in use, such as the Itronix GoBook MAX™.
In some embodiments, route data may be transferred to and from the mobile data collection system 108 using a removable flash card 213. For example, an operating system (not shown) associated with the mobile data collection system 108 may recognize the flash card 213 as a removable drive, allowing standard file access. In other embodiments, the routes may be transferred to the mobile data collection system via a local area network (LAN), a wide area network (WAN), etc. Periodic data backups to the flash card can be configured in the mobile collector applications component 204.
The mobile data collection system 108 also includes a radio based remote reading component 214, which, in some embodiments, may include a transceiver. The radio based remote reading component 114 may, via a radio antenna 215, send signals to wake-up meters that function in “wake-up” mode and to receive and manage incoming data. The mobile data collection system 108 may also include a Global Positioning System (GPS) component 216, a Global Information Services (GIS) component 218, or like systems, which may be used to facilitate mapping and other related functionality, such as route playback features.
In general, GPS uses a network of satellites that continuously transmit coded information that makes it possible to precisely triangulate locations on earth by measuring the distance from satellites. GPS signals broadcast line of sight, meaning that the signals will pass through clouds, glass, and plastic but will not pass through most solid objects, including people, buildings, and mountains. The GPS receiver provides increased accuracy of positioning data as the number of accessible satellites increases. Accordingly, aspects of the mapping component can be configured to inform the operator of the number of satellites available.
Where the GPS component 216 (or GIS component 218) is implemented, operators of the mobile data collection system 108 can use latitude and longitude coordinates to locate endpoints in the field and to track the progress of the mobile collection vehicle while driving the route. This information may also be used in implementing a playback feature, which is described in more detail below with respect to
Various user screens, views, and other interfaces may allow users to monitor and manage meter reading route activities. Examples of such screens are described with respect to
In some cases, the screens or pages provide facilities to receive input data, such as a form with fields to be filled in, pull-down menus or entries allowing one or more of several options to be selected, buttons, sliders, hypertext links, or other known user interface tools for receiving user input. While certain ways of displaying information to users are shown and described with respect to certain Figures, those skilled in the relevant art will recognize that various other alternatives may be employed. The terms “screen,” “web page,” and “page” are generally used interchangeably herein. The pages or screens are stored and/or transmitted as display descriptions, as graphical user interfaces, or by other methods of depicting information on a screen (whether personal computer, PDA, mobile telephone, or other) where the layout and information or content to be displayed on the page are stored in memory, database, or other storage facility.
When implemented as web pages or wireless content, the screens are stored as display descriptions, graphical user interfaces, or other methods of depicting information on a computer screen (e.g., commands, links, fonts, colors, layout, sizes and relative positions, and the like), where the layout and information or content to be displayed on the page are stored in a database. In general, a “link” refers to any resource locator identifying a resource on a network, such as a display description provided by an organization having a site or node on the network. A “display description,” as generally used herein, refers to any method of automatically displaying information on a computer screen in any of the above-noted formats, as well as other formats, such as email or character/code-based formats, algorithm-based formats (e.g., vector generated), or matrix or bit-mapped formats. While aspects of the invention are described herein using a networked environment, some or all features may be implemented within a single-computer environment.
In general, for ease in describing features of the invention, aspects of the invention will now be described in terms of a user (e.g., a mobile data collection system operator) interacting with the mobile data collection system.
A. System Performance Monitoring
In the illustrated embodiment, the dashboard view 300 provides a continuously updated summary of data collection system performance. Performance indicators can include the number of reads per minute 320, error or alert messages 322, the amount of free space available on a backup disk 324, the frequency and tones that the system is transmitting to read meters 326, the number of satellites available to a mapping system 328, etc. In addition, the dashboard view 300 may provide an indication of a current GPS position 330 of the vehicle.
In the illustrated embodiment, the reads per minute feature 320 shows the total number of new in route and out of route reads collected within a given time frame (e.g., over the last 60 seconds) in a speedometer-like display that refreshes periodically (e.g., every 15 seconds). The session alerts feature 322 displays the total number of uncleared alerts that is in an audit log, as well as the most severe alert that is currently active. In some embodiments, a bar (not shown) below the session alerts feature displays a color-coded warning, depending on the severity of the highest priority alert. For example, red may indicate a critical alert that requires immediate action, while orange may notify of a temporary malfunction or loss of data and yellow may indicate a condition where no immediate action is needed.
In some embodiments, the dashboard view may be displayed alone, while in other embodiments, it may be displayed in addition to other screens or views, such as a route mapping view.
B. Route Mapping
The mapping symbology also includes symbols for unread out of route endpoints (blue rectangle) 416 and read out of route endpoints (blue rectangle with white in the middle) 418.
Out of route endpoints also appear on the map, allowing the operator of the vehicle to make decisions on how to progress on the route (e.g., which street to turn on next). For example, if significant numbers of out of route endpoints are appearing on the map, this signals to the driver that he or she is nearing the edge or border of a route, and may need to change course.
In some embodiments, the map may be interactive by allowing users to drill down on specific endpoints. For example, clicking on or touching an out of route endpoint on the map may result in the display of specific information regarding the out of route endpoint, such as the specific information described with respect to
In some embodiments, the mapping functionality described herein may be combined with other functionality including voice enhancements, layering of maps to portray varying levels of detail (e.g., utility infrastructure vs. meters), or varying meter types (e.g., gas vs. electric vs. water), etc. Many combinations and features are possible.
C. Out of Route Meters
In some embodiments, the out of route view 800 may use information contained in the route file received from the utility or other source. In some embodiments, the mobile data collector captures the vehicle's location at the time the out of route endpoint was read, while any processing of the data may be performed remotely (e.g., at the host processor of
In some embodiments, the out of route view 800 includes a list portion 802 and a properties portion 804, so that users can compare multiple reads simultaneously (via the list portion 802) or focus on a single read (via the properties portion 804). A default sort order in the list portion 802 displays out of route reads by the time collected, beginning with the most recent and continuing in descending order. The out of route view 800 may show an endpoint ID 806, a latest endpoint reading for the endpoint 808 (e.g., kilowatt hours used), a message count for the endpoint 810 (e.g., the number of times the endpoint was heard at the time the reading was collected), a reading time 812, and an endpoint type 814 (e.g., ERT type), as reported by the endpoint.
The out of route view 800 may also provide information on the location of the out of route endpoint, and the location of the vehicle at the time it read the out of route endpoint. More specifically, the out of route view may provide endpoint latitude data 816, endpoint longitude data 818, vehicle latitude data 820, and vehicle longitude data 822. To facilitate the collection, storage, processing, and display of out of route endpoints, this information may be contained within one or more data structures. In addition, the data structures may include information used to facilitate the mapping the out of route endpoints (shown, for example, in
Based on the information related to out of out endpoints, the mobile data collection system may automatically determine an optimized driving path for the operator of the vehicle to take. This may be implemented using various mathematical computations and/or algorithms associated with the route and the geographic locations of the out of route endpoints. After the route is completed, the mobile data collection system may provide stored information relating to the out of route endpoints to a host processing system, or other system, where the information may go through additional processing. The utility service provider may then use this information to reconfigure or optimize meter reading routes and to otherwise increase the efficiency of the mobile collection system. For example, the information related to out of route meters may be used to automatically determine which endpoints to include within predetermined routes, thus reducing the number of out of route endpoints encountered on each route.
Other aspects of the user interface for out of route endpoints includes optional alerts that alert the operator of out of route endpoints while a route is being driven. Examples of alert sounds include high beeps, low beeps, rings, bells, etc. In the illustrated embodiment, a series of beep configuration choices are available to the user by selection of a radio button.
While the illustrated examples show out of route endpoints in a MAMR system, one skilled in the art will recognize that similar techniques can be implemented in fixed network meter reading systems and other systems without departing from the scope of the invention. Fixed network meter reading systems may include wireless and or wire line transmission of meter reading data over large areas without the use of a vehicle or other localized collection techniques.
D. Route Playback
The route playback component may be implemented, in part, using a logging feature that tracks the progress of the vehicle as it drives a route. As shown in
As shown in
While not shown in detail in
In some embodiments, like the mapping features shown with respect to
At decision block 1302, the routine 1300 determines whether the endpoint is an out of route endpoint (e.g., whether it is associated with the current route, whether it is associated with a route known by the mobile collection system, etc.). If at decision block 1302 the routine 1300 determines that the endpoint is not an out of route endpoint, the routine 1300 continues at block 1305, where the routine records and/or displays the information for an in route endpoint. If, however, at decision block 1302 the routine 1300 determines that the endpoint is an out of route endpoint, the routine continues at block 1303, where it records the received information for the out of route endpoint. In addition, the routine 1300 may record information about the location of the vehicle at the time the out of route endpoint was read. This information may be stored within a single data structure or within a combination of data structures.
At block 1304 the routine 1300 provides an indication of the out of route endpoint to the operator of the mobile data collection system. For example, the routine 1300 may show the out of route endpoint on a map, sound an alert when the out of route endpoint is read, add the out of route endpoint to a displayed list of out of route endpoints, or provide specific textual information for the out of route endpoint.
At block decision block 1306 the routine 1300 checks whether the route is completed (e.g., all meters on the route have been read). If the route is completed, the routine continues at block 1307, where the routine transmits completed route information to the host processing system. The routine 1300 then ends. If, however, at decision block 1306, the route is not completed, the routine 1300 loops back to block 1301 to receive the next endpoint reading.
At decision block 1404 the routine 1400 checks whether the route is completed (e.g., all meters on the route have been read). If the route is completed, the routine 1400 continues at block 1405, where the routine transmits the recorded route information to the host processing system (e.g., in the form of a log file). The routine 1400 then ends. If, however, at decision block 1404, the route is not completed, the time t is set to equal (t+1) and the routine 1400 loops back to block 1401 to record the next vehicle location.
