| Abstract: | Automatic weather stations are usually distributed at various regions widely and each of them transfers real-time observational data to DP center synchronously.A high-speed data processing system is designed for this given application in this paper.The designing project and realizing method of software are discussed in detail.In particular,the buffer which acquisition threads put data into and processing thread takes data from concurrently is discussed emphatically.It has indicated that the system implements high speed and accurate results,high stability and reliability. |
