摘要： A system and method for transmitting data from a utility meter, such as a power meter, is disclosed. A microprocessor housed inside the power meter obtains readings of various power indicia, stores the readings in memory, and determines an efficient means of formatting the data for transmission to a remote host computer for further processing and use. The data is selectively compressed to minimize the amount and size of data that needs to be transmitted. The microprocessor is mounted on a circuit board assembly within the power meter housing and interfaces between the meter board of the power meter and a transmitter. The transmitter communicates the formatted and potentially compressed data from the power meter to the remote host computer wirelessly or via hard-wired communication lines. The various power indicia include power usage or power quality information.

摘要： A method for wirelessly transmitting data from an utility meter, such as an electric meter, is disclosed. A microprocessor housed inside an energy meter obtains readings of various power indicia, stores the readings, processes the buffer to determine an efficient means of formatting the data for transmission using a radio frequency communications link. The method examines the plurality of readings and determines if values can be communicated by transmitting an initial reading and followed by the difference of the next reading from the previous reading. A special indication is transmitted to turn ‘on’ compression and allow the receiver to propertly interpret received data. Other indicators are transmitted to turn ‘off’ compression, turn on compression for a pre-defined limited duration, or vary the range of the difference between readings.
