基于RS485的大气数据前端传输系统设计与实现

Design and Implement of Atmosphere Data Former Transmission System Based on RS 485

为了在工农业生产中获取大气数据的详细信息,设计了一种利用RS 485总线把数据采集前端机、子站与中心站互连构成的数据前端传输系统,该系统的前端机对现场大气数据的采集与处理,并通过串口实现与子站、中心站的信息传输,有效完成大气数据的获取与传输。实际测试可见,系统实现了大气数据的采集与传输,可以满足实际工农业生产中获取大气数据的需要。

In order to acquire atmosphere data in industry and agriculture,data acquisition and communication system composed by former acquisition part,sub- stations and center station using RS 485 bus is designed. The former part acquires and processes the local atmosphere data and transmites data to sub - stations and center station through serial communication. Tests prove that the system can reliably acquire and communicate the atmosphere data and be applied in industry and agriculture production.
