Design And Realization Of Water Resources Distribution Image System Based On FPGA

The application of visual monitoring technology has always been an important issue in engineering research.In order to ensure the effectiveness and pertinence of the video monitoring,a full range of real-time monitoring is realized in different monitoring areas of the river.At the same time,in order to ensure the real-time and convenient monitoring of the water area,realize the dynamic monitoring of the river channel with multiple parameters and prevent the occurrence of pollution problems.In view of these actual needs,the imaging system can be better applied to the water resources monitoring system,this article proposes a method to realize fast imaging and monitoring based on FPGA through hardware acceleration.The main content of this paper include the following parts:(1)In order to meet the needs of wide-field,comprehensive and multi-parameter water resources monitoring,analysis of the current water environment monitoring technology research status and the problems existing in the traditional video image processing,And propose new solutions to existing problems,integrate system functions,based on the advantages of FPGA parallel processing and high real-time performance,The design of the multiple camera synergies with multi-sensor array combination of multifunctional integrated distributed system as water resources.(2)After analyzing the system functions and requirements,FPGA is used as the main control chip to design the combination of multi-camera collaboration and multi-sensor array,high-speed data cache,multi-mode display hardware circuit and PCB board drawing;The key technologies and difficulties in the system design arc analyzed,Using a top-down system architecture strategy,the system is divided into two parts,a multifunctional distributed data collection terminal and an information management monitoring platform,and the corresponding functional design of the system is completed.The engineering design process of the system,such as the structure of the system,logic function design and verification,high-speed data cache,video image algorithm processing and optimization,parameter information fusion,etc.,is described in detail.(3)The system functions including four-way video segmentation,video image and sensor parameter information fusion,and multi-mode real-time display have been systematically tested.The system function test is stable and reliable,the image sampling rate of 30 frames per second,and the highest transmission rate is up to 12Gb/s,the visual interface can dynamically process and display data in real time,To achieve a comprehensive grasp of river water quality and hydrological data,and the overall function can reach the expected design index.The results show that under the same environment,the speed and efficiency of traditional software for video image algorithm processing is far lower than the effect of FPGA parallel and pipeline processing,and there is a certain degree of innovation in technical implementation.
