摘要： Line voltage and line current signals are sensed on a power line having at least one conducting path. The sensed line voltages and line currents are converted into a digital signal. A phase-to-neutral voltage signal and phase current signal are computed from the digital signal to thereby define a phase of the power line. An interval of orthogonality is determined from the sensed voltage and current signals, coinciding with passage of an integral number of cycles of a fundamental frequency reference signal which is computed from the computed phase-to-neutral voltage signal. A vector metering quantity is computed for the determined interval of orthogonality from the computed phase-to-neutral voltage signal and the computed phase current signal. The vector metering quantities to be computed may be identified and computed based upon an associated detent. The vector metering quantity is also computed based on an identified circuit topology.

摘要： In one embodiment, the present invention is an algorithm implemented in a microprocessor-controlled system which, for example, is disposed within an energy meter housing. Particularly, the microprocessor is coupled to a communications interface which receives and transmits messages on a power line or some other external communications media. Upon receipt of a message, the commands contained in the message are read. If a command corresponds to a "buffer and lock" command, then a timer operated by the microprocessor starts to run. For example, if data to be retrieved from the system is data which is erased from system memory when read therefrom, just prior to reading such data, a buffer and lock command is transmitted by the external communication device. Upon receipt of such command, the microprocessor initiates running of a timer and the data is read from the meter. The data also is copied to a buffer, e.g., a RAM memory location. If the data is "lost" during transmission, and as long as the timer is running, the data can be copied from the designated buffer and re-transmitted. In this manner, data normally not saved in a meter subsequent to a read operation is saved and, if necessary, re-transmitted.

摘要： Methods and apparatus for controlling operation of a low frequency oscillator upon reset of a microcomputer to achieve faster start-up time are described. In one aspect, the present invention is directed to a microcomputer having an oscillator input port, an oscillator output port, and an oscillator control port, and an oscillator coupled to the microcomputer oscillator output, input, and control ports. The microcomputer is programmed to control the output on the oscillator control port so that upon reset, the output transitions from a low state to a high state in accordance with a preselected frequency for a preselected period of time. More particularly, and in one exemplary embodiment, the microcomputer controls the output on the oscillator control port upon reset so that for a preselected cycle, the output is high for approximately about one-half cycle, low for approximately about one-half cycle, and then high for approximately about one-half cycle. Upon completion of such cycling, the microcomputer transitions the output on the control port to a high impedance state. Such control of the low frequency oscillator decreases the oscillator start-up time. Specifically, by generating the control signal having the desired frequency as described above, and then providing such control signal to the oscillator, the oscillator is "kick started" to begin its operations more quickly than such operations would begin without such control signal.
