20100188254 | SYSTEMS AND METHODS FOR IMPROVING RECEPTION OF DATA IN WIRELESS COMMUNICATION ENVIRONMENTS - Generally described, the disclosed subject matter is directed to improving the reception of data in wireless communication environments. In accordance with one embodiment, a method is provided for improving the reception of meter data in an AMR system. In particular, the method includes obtaining a sample of data indicative of channel quality for each transmission channel in the operational frequency band of the endpoint device. Then, the data is analyzed and a determination is made as to whether the reception of data by the collection system can be improved. If the reception of data by the collection system can be improved, a command is generated for reprogramming the endpoint device. In one embodiment, the command includes channel reprogramming data for reprogramming the endpoint device. | 07-29-2010 |
20100188255 | RELATIVE TIME SYSTEM - A system, method and device are provided for obtaining, from each endpoint device, meter reading data where the meter reading data are recorded and managed based on a relative time clock in each endpoint device. The relative time clock may be a simple inexpensive clock that tracks minutes and triggers recording of meter reading data for a particular hour at the end of that hour. In that embodiment, a collection system sends an endpoint device a request that includes a requested time that is converted into a relative time so that the endpoint device can understand the request. Since each recorded interval is generated based on a relative time maintained by the clock in the endpoint device rather than an absolute (real) time, the endpoint device does not need to maintain accurate date/time or to read meter reading data from the utility meter based on a real date/time. | 07-29-2010 |
20100188256 | REQUESTED TIME ADJUSTMENT FOR ACCURATE DATA EXCHANGE - A system, method and device are provided for reducing consumption calculation errors caused due to time drift in an endpoint device. In one embodiment, the endpoint device transmits consumption data in response to a request for consumption data. The request generally includes a time period of the consumption data. The endpoint device adjusts the set of intervals based on the extent of the difference between the collection system time and the endpoint device time to obtain the most accurate intervals. The process for adjusting intervals can be implemented independently from time synchronization between the endpoint and collection systems. Further, the process for adjusting intervals does not result in updating the meter reading data that have been already logged and stored in the endpoint device. | 07-29-2010 |
20100188258 | TIME-DIVIDED COMMUNICATIONS IN A METERING SYSTEM - A method, system, and related apparatus for performing time-divided communications in a metering environment are disclosed. In one embodiment, an endpoint (e.g., ERT) is provided that implements a method for communicating messages with a remote device. Generally, the method includes causing the endpoint to transmit a standard meter reading message within a predefined frequency band. Then, after waiting a predetermined amount of time, a receiver on the endpoint is activated to listen for a message transmitted by the remote device. While the receiver on the endpoint is activated, the endpoint may receive a command from the remote device without being required to transmit an additional standard meter reading message. | 07-29-2010 |
20100188259 | FILTERING OF METER READING DATA - Packet formats and associated metering infrastructure for filtering meter reading data that is being transmitted by utility meters are disclosed. In one embodiment, a method suitable for being implemented in a metering environment is provided that filters meter reading data being received by multiple collectors. Specifically, the method includes ranking the relative ability of the plurality of collectors to capture transmissions from the same utility meter. Based on the relative ranking, at least one collector from the plurality of collectors is identified that will be configured to disregard transmissions that originate from the utility meter. Then, the method provides the collector with a read list for differentiating between transmissions containing meter reading data that will be forwarded to a utility service provider from transmissions that originate from the utility meter. | 07-29-2010 |
20100188263 | PRIORITIZED COLLECTION OF METER READINGS - Generally described, the disclosed subject matter is directed to improving the collection of GDT meter readings. In accordance with one embodiment, a method is provided for prioritizing the transmission and process of GDT meter readings in an AMR system. In particular, the method includes capturing a GDT meter reading that quantifies the consumption of a utility service at a utility meter. Then, during a reporting window, one or more packets of the GDT meter reading having a data item that identifies the enhanced priority level of the data is transmitted from the utility meter. When a collector receives the transmission, the elevated priority allocated to the transmission is identified. As a result, the collector causes the GDT meter reading to be forwarded to a host computer prior to the processing and transmission of other meter readings. | 07-29-2010 |
20100188938 | MEASURING THE ACCURACY OF AN ENDPOINT CLOCK FROM A REMOTE DEVICE - Packet formats and associated metering infrastructure for filtering meter reading data that is being transmitted by utility meters are disclosed. In one embodiment, a method is provided of measuring the accuracy of an endpoint clock, such as a utility meter clock, from a remote device configured to capture transmissions that originate from the utility meter. Generally, the method includes synchronizing the time maintained by the utility meter with the time maintained by the remote device. The method receives and decodes a packet that includes a time stamp provided by the utility meter. Then, the method calculates the extent of the inaccuracy of the time stamp in the received packet and determines whether the extent of the inaccuracy satisfies a predetermined threshold. | 07-29-2010 |
20100192001 | DEVICE TIME ADJUSTMENT FOR ACCURATE DATA EXCHANGE - The clock of an endpoint device is adjusted to a collection system time in a meter reading system where the endpoint device is employed to read and record meter reading data for calculation of consumption data. Specifically, the meter reading data are recorded as a fixed number of intervals in such a way that the calculation of consumption data can be requested by indication of the number of intervals and the start interval. In one aspect, the endpoint device time is adjusted to an external clock to calculate accurate consumption while the process for adjusting the endpoint device time does not result in creating very short/long intervals, nor updating the meter reading data that have been already logged and stored in the endpoint device. | 07-29-2010 |

20110050456 | VERSATILE RADIO PACKETING FOR AUTOMATIC METER READING SYSTEMS - An automatic meter reading (AMR) system utilizes versatile radio packets that are recognizable by AMR system receivers capable of receiving conventional interval data message (IDM) radio packets. A versatile radio packet includes a packet preamble portion, a packet body portion, and a packet validation portion. The packet preamble portion has a frame synchronization bit sequence that is recognizable by existing or conventional encoder-receiver-transmitter (ERT)-compatible AMR system receivers, such as a bit sequence equal to 0x16A3. The packet preamble portion also has a packet type identifier field and a packet length field. The packet body portion includes at least an endpoint serial number field and a message, where at least the message has a variable length. Optionally, the message includes a message type identifier field and a message value field that can have a plurality of sub-fields. The AMR system may use message type identifiers optionally present in the versatile radio packets to filter, or discriminate between, certain message types at the reader level. Versatile radio packets can enable endpoints and other devices in the AMR system to transmit a variety of new information to existing AMR infrastructure without having to conduct a significant infrastructure overhaul of the AMR system. | 03-03-2011 |
