摘要
介绍了以RS-485为控制总线的海气边界层监测系统设计。通过RS-485总线,监控主机与数据变送器和智能传感器可以直接进行通信,简化了系统结构,实现了系统测量节点的分散控制和集中管理。给出了系统主控制板的硬件组成框图,描述了硬件设计原理和通讯协议设计,给出了主程序流程图。经过实际应用表明,该系统具有安装使用方便,可靠性高的特点。
An air-sea boundary layer monitoring system based on RS-485 bus is introduced.The monitoring host computer can communicate with the data transmitter and the intelligent sensors directly via the RS-485 bus,thus simplifying the system structure and realizing distributed control and concentrated management of the measurement nodes.The main control board block diagram of the system,hardware design,communication protocol design and main program flow chart are discussed.The application shows that the system is easy to install and has high reliability.
