摘要： Various aspects of the instant disclosure are directed towards a method for communicating time-based data in a power line communication system. In accordance with one or more example embodiments, firmware is downloaded to a multitude of endpoints over power distribution lines carrying alternating current (AC) power. Endpoint devices targeted for changes to stored firmware are grouped and the firmware is delivered in chunks to each group. As devices receive a particular chunk of firmware, the device advances to a next stage and provides information indicative of this stage, based upon which subsequent chunks of firmware are communicated. This occurs (e.g., on a daily cycle) until the endpoint has received all firmware for an update, after which the endpoint(s) are re-started using the firmware. Accordingly, such updates can be carried out in a cyclic and verifiable manner.

摘要： Aspects of the present disclosure are directed towards a data retrieving engine that is designed to retrieve interval data from the endpoint devices that is communicated for indicating utility usage readings. The interval data is provided at least once for each interval period (used by each of the endpoint devices). The data retrieving engine is additionally designed for retrieving, from the endpoint devices, other different type of data, which is transmitted over a time period that overlaps multiple interval periods. In certain implementations, the system allows a dynamic adjustment to a ratio of the respective amounts for each type of data.

摘要： Aspects of the present disclosure are directed toward the use of broadcast transmissions to multiple endpoint devices. These broadcast transmissions can be particularly useful for reducing the communication bandwidth used during transmission of configuration data to the endpoint devices. In order to implement the broadcast communications, the present disclosure describes a mechanism for configuring targeted endpoint devices to be responsive to the broadcast communications. For instance, a configuration command can be sent to each of the targeted endpoint devices. The configuration command can include a virtual ID. The targeted endpoint devices can configure themselves to listen for subsequent broadcast messages addressed to the virtual ID. Configuration data can then be sent using the virtual ID and associated broadcast messages.

摘要： An endpoint processor includes a processor block, a timer block, a memory block, and analog-to-digital converter. The timer block is arranged to provide a time based signal to the processor block. The memory block cooperates with the processor block. The analog-to-digital converter is arranged to provide an interface between an analog signal and the processor block. The analog signal includes encoded data from a power signal. The processor block is arranged to control a sampling rate that is associated with the analog-to-digital converter such that the analog signal is down-converted as an under-sampled signal. The processor block is arranged to extract the encoded data from the down-converted signal by executing a digital signal processing algorithm that is stored in the memory block. The digital signal processing algorithm is arranged to reject fundamental and harmonic frequencies that are associated with a power-line frequency that is associated with the power signal.

摘要： Aspects of the present disclosure are also directed towards a method that includes maintaining a transmission period which has a start time and an end time synchronized to metrological time. Further, this method, in response to the start time, begins transmission of a frame, which includes a plurality of symbols. This transmission occurs over power distribution lines that carry power using alternating current (AC). This method also includes synchronizing a transmission time for each symbol of the plurality of symbols according to a time-based parameter of the AC. In response to reaching an end of the frame, a synchronization symbol period is determined for a synchronization symbol, as a function of the transmission times, for the plurality of symbols and time from the end of the frame to the end time. The synchronization symbol is then transmitted on the power distribution lines.

摘要： Particular embodiments are directed towards a method for communicating time-based data in a power line communication system. The communication system utilized in the method includes: a command center; a collector device; and a plurality of endpoint devices. The method includes communicating, from the collector device, downstream data to the plurality of endpoint devices. This downstream communication utilizes a communication protocol that is relative to a collector network time, and is over a set of power distribution lines carrying alternating current (AC). The collector network time uses the local oscillator. The AC zero-crossing event can be used as a time base for other versions of the network time. Conceptually, the AC can be thought of as acting as a reference clock for maintaining these other network times, although the clocking function can be carried out in the digital realm, e.g., using a digital-signal processor (DSP).

摘要： An endpoint in a power distribution system includes a transmitter. The transmitter includes a transformer, a half-bridge driver, a first and second driver, and a resonant circuit. A primary winding from the transformer is coupled to a power distribution line, while the secondary winding is coupled to the transmitter. The half-bridge drive circuit selectively asserts drive signals. The resonant circuit has a natural resonant frequency in an audio frequency range. The half-bridge driver is arranged to selectively activate the first and second drivers such that the power-line is modulated with a square-wave signal at a frequency that is associated with encoded data. The half-bridge driver circuit can also be arranged to provide power to the transmitter, and to the endpoint.
