High speed data acquisition and processing system for precipitation detection Based on linear CCD

摘要

In order to realize automatical observation of Precipitation, Optical precipitation auto-measurement system is designed based on linear image sensor. Considering the mass acquisition data which are inconvenient for transmission and processing under continuous operation, real-time binarization and encoding processing of linear image data are carried out by Field Programmable Gate Array (FPGA). Original data or encoding data can be transmitted based on TCP/IP protocols and Ethernet. Dual-ports RAM and internal FIFO are designed for data buffer unit and data compare unit in this system, so it can meet the demand for high speed data collecting, transfer and processing. The structure of the system is simple, low cost and has wide application prospect.
