Abstract: A method and system for monitoring utility meter status, and transmitting a status message via an output device connected to a universal communications interface in the event that the utility meter status meets a predetermined condition. Typically, the predetermined condition is a power loss, signified by a drop in voltage or current. The system is connected to a utility meter, such as an electric meter. The voltage level of the electric meter is monitored through a voltage input interface. An analog-to-digital converter transforms the voltage waveform into a series of digital data packets, which are then transmitted to a microprocessor. The microprocessor monitors the digital signal for a power loss indication, or other predetermined condition. Once a predetermined condition is met, the microprocessor transmits a status message across a universal serial bus to a universal communications interface.

Abstract: A telephone-based automatic meter reading (AMR) system includes a telemetry device through which a host computer can collect meter readings remotely. So that the telemetry device does not interfere with customer usage of other telephone devices on the telephone line, an apparatus and method is provided which enables the telemetry device to sense both the static off-hook status and the dynamic off-hook status of the telephone line. Numerous circuit components in the telemetry device are shared in sensing both the static and the dynamic off-hook status. Whenever it is determined that a telephone device is, or has become, off-hook, the telemetry device is prevented from using the telephone line. Isolation between the telephone line and the meters is ensured using a transformer and optocouplers.

Abstract: An architecture for communicating with telemetering interface units (TIUs). The system comprises an application controller which interfaces with service vendors who make requests for telemetering metering actions and/or control actions; or network server for communicating via UTTs, (Utility Telemetry Trunks), with an end office switch for accessing TIUs, using a suppressed ringing connection to distinguish between telemetering connections and telephone connections; a service control point (SCP), for providing data about the telecommunications network, the data being necessary in order to allow the network server to access the correct TIU, and a data network for interconnecting the application controller, network server and switching control point. Advantageously, using this arrangement, the functions of the application controller which interfaces with the service vendor are segregated from the functions for controlling the telecommunication network to access the TIU.

Abstract: Conventional AMR and DA/DSM systems typically suffer from a lack of extensibility due to the monolithic nature of the master station software. In contrast, this patent describes a system that is comprised of small modules connected using a component object model. This system allows straightforward extension in the areas of applications, communications, metering devices, and databases without requiring recompilation or relinking of the system. Furthermore, this system allows commercial applications such as spreadsheets, word processors, statistical packages, report generators, et cetera to be integrated directly with this system, and allows extension and customization of the system using such packages. Such a flexible open architecture is very attractive to utilities in that it allows easy extension by the utility or other third party developers without the involvement of the original authors of the system.

Abstract: A telephone-based automatic meter reading (AMR) system includes a telemetry device through which a host computer can collect meter readings remotely. The telemetry device has one or more ports to read one or more meters at pre-scheduled time intervals. All data read from the meter(s) is stored in a non-volatile memory in the device, and the collected data is transferred back to the host computer according to a predetermined schedule (with a call back interval that can be hourly, daily, weekly or monthly). An apparatus and method is provided which enables the host computer to initiate a special data stream to invoke a powerless circuit portion of the telemetry device—specifically, a telephone-side portion which is electrically isolated from the meter-side circuitry (such as by an optocoupler). The ringing signal on the phone line powers the circuitry in this telephone-side portion of the device such that no AC connection or separate battery power is required.

Abstract: A meter reading system preferably includes an external modem module (EMM), a hub and a data collection system. The EMM communicates with one or more utility meters and, as such, is preferably selected on the basis that it incorporates a communication format that is compatible with the communication format of the utility meter such that the utility meter does not require modification to be communicatively coupled to the EMM. The EMM obtains meter data from the utility meter and converts to a radio frequency communication format. The radio frequency formatted data is then transferred to the hub. The hub then translates the radio frequency data into an analog or digital telephone communication format, which is then transferred to the data collection system for use by the utility as desired, e.g. utility billing, tracking, control, etc.

Abstract: The system for direct suppressed ringing access of a subscriber line enables the service provider to access subscriber lines from any location, as long as the incoming call is identified and authenticated as a suppressed ringing access call. The central office switch can maintain a list of predefined line numbers that are used by an authorized service provider to perform the suppressed ringing access function. Thus, a call origination on one of these lines is automatically validated as a suppressed ringing connection call. Alternatively, the suppressed ringing connection is requested by the inclusion of a predefined code in the dial string and the central office switch automatically authenticates the identity of the service provider.

Abstract: The usage detection system establishes a suppressed ringing connection to the subscriber line for either a predetermined extended time interval to enable at least two successive usage readings to be taken, or for a duration as determined by the telemetry equipment to perform the necessary usage readings to detect the presence of usage anomalies. This usage detection system communicates with the serving central office to establish a suppressed ringing connection, the duration of which is either under the control of the usage detection system or the telemetry equipment located at the customer premises. The usage detection system communicates with the telemetry equipment to identify the usage measurements that are desired.

Abstract: An automatic meter reading data communication system having an integrated digital encoder and two-way wireless transceiver that is attachable to a wide variety of utility meters for meter data collection and information management. The integrated encoder and transceiver communicates commodity usage information over a two-way 900 MHz spread spectrum local area network (LAN) to a remotely located communication node. The communication node transmits this data to a utility service provider over a commercially available fixed wide area network (WAN). The utility service provider may also request data from the communication node over the same fixed wide area network.

Abstract: A method for billing consumers of on-demand commodities consumed at a site remote from the site at which they are produced. It is modeled after certain contemporary telephone-company billing practices, though it is not limited to use with telephone companies. In one embodiment the method uses a telephone service provider to bill and collect for monies owed to the producer of the commodity for the amount of the full commodity units consumed during a billing period. In a simple embodiment of the method, commodity-consumption information is sent to the billing service by an automatically reading meter located at the point where the commodity is delivered for consumption. In particular, this commodity meter—such as an electric power meter—is designed to generate a discrete signal each time that a predetermined commodity-billing-unit has been consumed.

The premises gateway can communicate analog signals and broadband signals on a twisted pair to the same node. The premises gateway can also be provided at a central office to operate as an Internet protocol gateway.
