A data collection and transmission system of marine sensor based on power line carrier

In order to apply power line carrier technology to data transmission,current power line carrier technology based on 220 VAC is developed and updated by implementing power line carrier technology based on 500 VAC and a shipborne data collection and transmission based on 500 VAC is designed to collect shipborne five resistive load voltage and current values and fifteen hydraulic values,while the 500 VAC output control circuitry is designed to reduce underwater module power consumption. System mainly consists of STM32F107 processor and the improved 500 VAC power line carrier modules,which serves as data transceiver modules,and realizes the shipborne data collection and transmission and bit error rate testing in application layer. The communication test show that the data can be transmitted to the human-computer interaction platform in reliability,which can met the requirement of design.
