利用RS-485总线实现气象要素分布式自动采集

Using RS-485 Bus Actualize the Distributed Collection of the Weather Factor Automatically

探讨了在RS485总线上运行ModBus通信协议,构建气象要素分布式自动采集系统的可行性和先进性,提出依此方案实现自动气象站标准化。

Our system will be adopt the RS-485 bus, it meanings that the RS-232 of master computer is switched RS-485 bus to test and control the modules which are made up of the correspondence weather factors and collect the weather factor. We expect to form the observation standard of the earth surface weather factor automatically and the product universally.
