摘要:
The present specification generally relates to the field of reading of measurements and particularly discloses a method and arrangement for providing measurements from a decentralized solution. The system is adapted to have an improved redundancy in a more robust construction that provides additional functionality and comprises a detection unit, a collection unit and a central unit.
摘要:
A communication module uses information received from a metrology module within the same network device and information about the properties of the specific metrology module, such as supply capacity and pulse volume, to determine when an error condition exits. The communication module accumulates pulses during an accumulation interval and compares the number of pulses accumulated during the accumulation interval to a threshold number of pulses to determine whether an error condition exists. If there is an error condition, then the communication module generates an alert and may transmit the alert without waiting for a scheduled communication.

摘要:
Determination of electrical network topology and connectivity are described herein. A zero-crossing is indicated at a time when the line voltage of a conducting wire in an electrical grid is zero. Such zero-crossings may be used to measure time within a smart grid, and to determine the connectivity of, and the electrical phase used by, particular network elements. A first meter may receive a phase angle determination (PAD) message, including zero-crossing information, sent from a second meter, hereafter called a reference meter. The first meter may compare the received zero-crossing information to its own zero-crossing information. A phase difference may be determined between the first meter and the reference meter from which the PAD message originated. The first meter may pass the PAD message to additional meters, which propagate the message through the network. Accordingly, an electrical phase used by meters within the network may be determined.
摘要:
Disclosed are techniques to minimize the electricity consumption of battery powered devices during network communications and performance of other functions. Example techniques include efficiently discovering other mains powered and battery powered devices within communication range of the battery powered device. In another example, techniques enable a battery powered device to serve as a relay for one or more other battery powered devices. In another example, techniques ensure that transmissions to and/or from battery powered devices are delivered efficiently and with low latency. In yet another example, techniques determine whether and under what conditions a battery powered device should migrate from one network to another. In the event of migration, example techniques minimize battery consumption associated with the migration.
摘要:
A distributed metering platform virtualizes functions of a conventional metrology sensor and separates the virtualized functions from a metrology sensor. One or more virtual meters or applications may be instantiated at a network communication device that is remote from the metrology sensor and processes metrology data received from the metrology sensor. Each virtual meter may include multiple partitioned application spaces that are isolated from one another. In one example, a first application space includes a locked version of code and a second application space includes an unlocked version of code. Furthermore, each virtual meter may be isolated from other virtual meters such that each virtual meter is unable to affect operations and/or data associated with other virtual meters.
