【Abstract】 In order to realize the remote monitoring of cathodic protection status of buried steel pipeline, a design method of sacrificial anode intelligent cathodic protection system for buried steel pipeline was proposed based on FPGA technology. Field programmable gate array(FPGA) was used as parallel processing unit to realize the acquisition of cathodic protection parameters. Two high-speed communication modes include wireless 4G and Ethernet were used for remote real-time monitoring and repeated reading of local data, which solved the problem of data loss caused by network interruption. The experimental results show that the intelligent cathodic protection system has the characteristics of accurate acquisition, reliable storage and timely monitoring, and can satisfy the needs of field engineering application.更多还原
