System and method of data reduction for cellular M2M transmissions from energy management systems

A method for reducing transmitted data from an energy management system, the method comprising:

• filtering the data from the plurality of data sources using a schedule comb and a delta comb, wherein the schedule comb reduces the data according to data schedule rules stored in a data definition database and the delta comb reduces the data by eliminating data values that have not changed since a previous transmission, the schedule comb and delta comb producing a reduced data set;
• formatting the reduced data set into a formatted data set using a data encoder;
• storing the formatted data set from the data encoder;
• receiving a trigger to send the formatted data set, wherein the queue generates the trigger when the queue reaches a trigger size;
• compressing the formatted data for transmission;
• and
• transmitting the compressed data to the monitoring center.

A system for transmitting data from an energy management system, the system for transmitting comprising:

• a microcontroller communicatively coupled to a plurality of data sources and comprising;
• a critical event evaluator receiving data from the plurality of data sources, the critical event evaluator monitoring the data for critical events requiring immediate transmission to a monitoring center;
• a schedule comb and a delta comb receiving the data from the plurality of data sources, the schedule comb reducing the data according to data schedule rules stored in a data definition database and the delta comb reducing the data by eliminating data values that have not changed since a previous transmission, the schedule comb and delta comb producing a reduced data set;
• a data encoder operable to format the reduced data set into a formatted data set;
• and
• a queue for storing the formatted data set from the data encoder.
