A Dummy Active Resistance to Transmit the Navigational Parameters of an ROV

The task of monitoring the systemic parameters of an ROV requires a reliable and robust communication platform. The optical data transmission which is the most practical method for long range communication in ROV application has multiple inherent drawbacks due to complexity of the system, maintenance and cost. A novel technique discussed in this paper introduces a communication layer over the existing power platform. An active resistance acting as a dummy load is controlled to consume certain power, thus, generating current modulation that is sensible by the supplying unit. Nevertheless, the user needs to define a coding protocol such as a lookup Table for data comparison purpose. As an outcome, a novel power-line method has enabled the ROV system for a real time transmission is presented. The signal correction and data computational methods and calibration are also discussed.
