`WIDE AREA REMOTE TELEMETRY
`
`CROSS REFERENCE TO RELATED
`APPLICATIONS
`
`The present application is related to U.S. Provisional
`Patent Application Ser. No. 60/058,978, filed Sep. 12, 1997,
`entitled WIDE AREA REMOTE TELEMETRY and U.S.
`
`Provisional Patent Application No. 60/094,057, filed Jul. 24,
`1998, entitled WIDE AREA REMOTE TELEMETRY,
`which are incorporated herein by reference.
`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`
`The present invention is directed to the fields of automatic
`meter reading of electric, gas, water meters and other
`systems, automatic reading of flow data, monitoring of such
`usage, and distribution of information thereon.
`The need for near real-time information is becoming
`critical to the efficient operation of many types of industries.
`This invention addresses a need for information from remote
`
`monitoring locations. This disclosure will center on pre-
`ferred embodiments of a monitoring system for the electrical
`and gas utility industry, although this monitoring system
`could be used for other areas such as gas pipeline metering,
`pipeline monitoring, water system monitoring, security
`systems, vending machines, energy control devices, or other
`areas where remote monitoring is necessary.
`The need for near real-time information from remote
`
`locations is becoming more pronounced due to the deregu-
`lation of several industries. For the utility industries, deregu-
`lation means an increase in competition which demands
`increased efliciencies in the utility systems. These increased
`efliciencies require better information about, and better
`control over,
`the systems involved. Increased efliciency
`heightens the need for near real-time information monitor-
`ing. Thus,
`the utilities need the ability to obtain near
`real-time information on consumer demand, supply, and
`overall system operations.
`As an example, electric utilities need this information to
`balance the generation of electricity against consumer
`demand, and to operate the transmission system as efli-
`ciently as possible.
`In general, electricity is generated at a generating plant,
`transformed for
`transmission over distances, and trans-
`formed again for the distribution to customers. The deregu-
`lation of the electrical utility industry will require innovative
`solutions to balance the generated electrical supply against
`the consumer demand for electricity. These solutions will
`require a reduction in the system costs, by increasing the
`system efliciencies, to match the competition levels of the
`deregulated industry. An increase in the electrical transmis-
`sion system efliciency will require access to remotely-
`located consumer-usage information to enable the utilities to
`eliminate the excessive generation of electricity. Thus,
`increasing the system efliciency will require the utility to
`reduce excessive generation and balance the amount of
`generated electricity against the consumer demand.
`The onset of deregulation of the electrical utility industry,
`and other similar industries, will result in unbundling of
`utility operations and segmenting of the marketplace.
`Deregulation will widen the gap between the supplier and
`consumer and increase the competition in the industry. This
`widened gap and increased competition results in the for-
`mation a new type of organization in the electrical utility
`industry called the independent sales organization (ISO).

`The ISO will operate as an intermediary between the elec-
`trical generating facilities and the consumers by buying
`generated electricity,
`transmitting it from the generating
`location to the consumer area, and reselling the electricity to
`the consumers.
`
`Bulk users of electricity will generally have more nego-
`tiating power in the purchasing of electricity. To take advan-
`tage of bulk rates, local consumers may join together to form
`a distribution pool which has associated demand levels and
`other characteristics. These distribution pools of customers
`will compare prices for electricity and purchase electricity
`from the lowest cost supplier or ISO. Because of varying
`electricity prices, the electricity bought and sold by an ISO
`for use in a particular distribution pool of customers, such as
`Tulsa, Okla., may actually be generated in remote locations,
`such as Colorado on one day and in Florida on the next.
`Thus, potential problems will arise in balancing the
`generation, transmission, and usage of the nation’s electrical
`transmission system. To avoid these problems, the ISO will
`need increased access to information in order to predict
`customer demand, purchase electricity, and resell the elec-
`tricity to the consumer.
`The present invention is additionally capable of providing
`a number of services to energy users such as energy usage
`analysis, energy management services, Internet
`inquiry
`services, and billing services.
`2. Prior Art
`
`Systems and methods for monitoring various types of
`meters, and collecting information to a centralized location
`are widely described in the prior art. Examples of these
`systems can be seen in the following patents:
`U.S. Pat. No. 4,940,976, issued to Gastouniotis et al. on
`Jul. 10, 1990 describing an AUTOMATED REMOTE
`WATER METER READOUT SYSTEM; U.S. Pat. No.
`5,053,766, issued to Ruiz-del-Portal et al. on Oct. 1, 1991
`describing a TELEMETERING SYSTEM FOR ELECTRI-
`CAL POWER CONSUMED BY VARIOUS USERS; U.S.
`Pat. No. 5,451,938, issued to Brennan, Jr. on Sep. 19, 1995
`describing a RF METER READING SYSTEM; U.S. Pat.
`No. 5,475,867, issued to Blum on Dec. 12, 1995 describing
`a DISTRIBUTED SUPERVISORY CONTROLAND DATA
`ACQUISITION SYSTEM; and U.S. Pat. No. 5,673,252,
`issued to Johnson et al. on Sep. 30, 1997 describing a
`COMMUNICATIONS PROTOCOL FOR REMOTE DATA
`GENERATING STATIONS. A brief discussion of these
`
`various examples is outlined in the following discussion.
`U.S. Pat. No. 4,940,976, issued to Gastouniotis et al. on
`Jul. 10, 1990 describes an AUTOMATED REMOTE
`WATER METER READOUT SYSTEM. This system cre-
`ates a periodic electrical signal whose frequency is propor-
`tional to the flow rate. This signal is stored into a solid state
`counter from which this information is transmitted to a
`
`remote receiver by a standard radio frequency telemetry
`link. The receiver stores the information for multiple meters
`and periodically sends the data to the data processing oflice
`by means of a telephone line, CATV cable, or RF link. The
`transmitting link between the solid state counter and the
`remote receiver occurs every time the flow counter is
`incremented as well as periodically whenever a timer gen-
`erates a pulse.
`’976 patent uses sensing and
`The Gastouniotis et al.
`transmitting units which both randomly and periodically
`sends one burst of consumption data at times throughout the
`day to the receiving interface unit for the area. This data is
`then accumulated in memory which is disgorged to the
`central billing site either periodically or on demand. This

`system teaches away from the use of multiple transmission
`to assure successful information transmittal. This system
`does not disclose any method for signal verification of the
`transmission from the sensing and transmitting unit.
`In
`addition, this system teaches an ineflicient method of double
`counting the usage information and then dividing it before
`transmitting.
`U.S. Pat. No. 5,053,766, issued to Ruiz-del-Portal et al. on
`Oct. 1, 1991 describes a TELEMETERING SYSTEM FOR
`ELECTRICAL POWER CONSUMED BY VARIOUS
`
`USERS. This system monitors consumer power usage from
`meters with disk revolution indicators of power consump-
`tion by utilizing a pulse generator, light generating LEDs,
`light and dark regions on the revolving disk, and sensors
`which monitor the passage of the light and dark regions of
`the revolving disk. The system detects and monitors disk
`revolutions and uses a sending means for transmitting a
`consumption signal to a meter concentrator, and a means for
`communicating the information acquired into a central com-
`puter.
`U.S. Pat. No. 5,451,938, issued to Brennan, Jr. on Sep. 19,
`1995 describes a RF METER READING SYSTEM. Bren-
`nan ’938 collects data from the meter and stores the data for
`
`transmission. At preselected pseudorandom timing intervals,
`the transmitter encodes the data, creates a synch signal, start
`signal, message signal, and a verification signal. The RF
`transmitter sends the information signals to the RF receiver
`which identifies the start signal, receives the transmission,
`and verifies the accuracy of the transmission.
`U.S. Pat. No. 5,475,867, issued to Blum. on Dec. 12, 1995
`describes a DISTRIBUTED SUPERVISORY CONTROL
`
`AND DATA ACQUISITION SYSTEM. This system is
`designed to overcome the inherent problems in short range
`radio broadcast communication by using supplemental con-
`trollers to enhance the transmission and control range of
`master controllers. Supplemental controllers are placed
`within the range of the master controller, but are capable of
`broadcasting to supplemental remote terminal units outside
`of the master controller’s range. The supplemental controller
`transmits messages from the master controller to the supple-
`mental remote terminal units, and relays responses from the
`supplemental remote terminal units. This allows for the
`supplemental remote control units to be placed outside the
`normal broadcast range of the master controller and, thus,
`extend the operating range of the master controller.
`U.S. Pat. No. 5,673,252, issued to Johnson et al. on Sep.
`30, 1997 describes a COMMUNICATIONS PROTOCOL
`FOR REMOTE DATA GENERATING STATIONS. This
`
`the
`system is used to gather information and transmit
`gathered information to a central location. Specifically, this
`system uses a Network Service Module (NSM) which
`communicates with a Remote Cell Node (RCN). The RCN
`communicates through an optional Intermediate Data Ter-
`minal (IDT) to get information to a Central Data Terminal
`(CDT). As an alternative to the separate IDT,
`the IDT
`functions may be implemented by the CDT.
`In Johnson ’252, the NSM is used to acquire information
`from utility meters, disconnect service, manage load, or
`monitor
`for alarm conditions. The NSM includes a
`
`transmitter, processor, memory, antenna, and optionally
`includes a receiver. The NSM processor monitors, collects,
`and arranges acquired information into packets of data for a
`pre-determined monitoring scheme and stores the acquired
`data in memory. Once the NSM has acquired a period or
`segment of data for
`the monitoring scheme,
`the NSM
`transmits all of the acquired data as a data packet. This

`transmission takes place at a predetermined time period over
`a single frequency to th e RCN. Alarm messages are not
`stored into memory, but are immediately transmitted to the
`RCN. The NSM transmits and can receive information
`through this first frequency and can also receive information
`through a second carrier frequency. The NSM is designed to
`utilize a maximum of two frequencies which are controlled
`by the design of the unit.
`Johnson ’252 collects information through the RCN
`which receives, stores, and processes the NSM signals. The
`RCN includes a transmitter, receiver, processor, memory,
`and antenna. The RCN receives the NSM data packets and
`temporarily stores them in memory. The RCN then collates
`the information, identifies duplicates of NSM data packets
`already transmitted by other RCN modules and acknowl-
`edged by IDT modules, and deletes the duplicate NSM data
`packets from its memory. The RCN transmits its collated
`information as a single packet of RCN information when
`polled by the IDT and deletes the stored information upon
`acknowledgement of the transmission by the IDT.
`Johnson ’252 either uses an IDT or a CDT which per-
`forms the functions of an IDT. The IDT includes a
`transmitter, processor, memory, and receiver. The IDT trans-
`mits a polling signal
`to the RCNs, receives the RCN
`information, transmits an acknowledgment of the receipt of
`the RCN information, and stores the RCN information in
`memory. The IDT collates the RCN information and deletes
`any duplicate NSM data packets to form IDT information
`which is sent to the CDT.
`
`The Johnson ’252 CDT element includes a transmitter,
`receiver, processor, and memory. The CDT receives IDT
`information and deletes any duplicate NSM data packets.
`The CDT then processes and stores the received informa-
`tion.
`
`The prior art as evidenced by the described patents suffers
`from excessive duplicate information transmission, required
`polling for second layer information retrieval, being overly
`complicated, and having excessive parts which are suscep-
`tible to failure. Further, the systems disclosed in the patents
`do not appear to maintain temporary duplicate information
`at efficient levels for transmission failures and other system
`problems.
`there remains a need for a simplified remote
`Hence,
`sensing information collection and information distribution
`system which addresses these and other problems.
`SUMMARY OF THE INVENTION
`
`The need for near real-time processed information on
`consumer utility usage which is available to the utility or
`other parties will require innovative solutions to remote-
`device system monitoring. An effective monitoring system
`can be developed through the use of a sensor interface
`module, a data collection module, commercially available
`information transmission systems, and a host module.
`The sensor interface module will constantly monitor
`individual customer demand and usage to gather information
`for the monitoring system. The sensor interface module will
`send this information to the data collection module over
`
`unlicensed radio frequency bands. The data collection mod-
`ules will gather the information from sensor interface mod-
`ules or other inputs wired directly and transmit the infor-
`mation to the host module over the commercially available
`information transmission systems. The host module will
`gather, store, and process the information from the sensor
`interface modules as needed, and communicate through
`commercially available information transmission systems to
`send the processed information to the appropriate consumers
`as desired.
