Abstract
Pipeline centerline mapping and cathodic protection effectiveness detection play an important role in pipeline positioning and safety protection.Aiming at the characteristics of inertial navigation mapping and cathodic protection effectiveness detection with strong real-time performance and large amount of data,a high-speed data processing and acquisition design scheme based on FPGA technology is proposed.A data acquisition system which can transmit various high speed detection signals is developed.The system can simultaneously record a variety of high-speed signals,including inertial derivative data,pipeline cathodic protection signals,etc.The system is small in size,low in power consumption and high in integration,and can meet the requirements of long distance pipeline inspection.Through the experimental simulation,the results show that the acquisition system has high processing efficiency and fast data storage speed,and has certain practical value in high-speed data processing and acquisition such as inertial navigation mapping and cathodic protection effectiveness detection.
