SYSTEMS AND METHODS FOR COMMUNICATING DATA OF A POWER TRANSMISSION LINE

摘要

Distributing sensing systems that are capable of wirelessly communicating power and data over power lines are provided. The distributed sensing system may comprise a distributed sensing portion and a primary portion. The distributed sensing portion may include a sensor, an analog to digital converter (“ADC”) and a microcontroller. The sensor may be capable of monitoring a parameter. The sensor may be configured to output an analog reading. The ADC may be configured to convert the analog reading to a digital signal. The microcontroller may be configured to modulate a power signal to encode the digital signal in the power signal. The primary portion may be configured to wirelessly receive the power signal from the distributed sensing portion. The primary portion may include a signal demodulation module. The signal demodulation module may be configured to extract the digital signal from the power signal.
