本文描述了人工降雨车的APPLE-Ⅱ微机控制自动化系统的结构,指出“开环SCC方式”有较强的抗干扰能力。提出了一种适用于开环SCC方式的变增益调节器,并设计了一种简单、价廉、线性度好的模拟量光电耦合传递电路。最后,本文介绍了开环SCC方式下的人工降雨车自动控制与降雨参数采集的程序框图。
This paper describes the structure of APPLE-Ⅱ microprocessor controlled automation system of artificial rainfall vehicle, and points out that “open-loop SCC method” has strong anti-jamming capability. A variable gain regulator which is suitable for open loop SCC is proposed. An analog photoelectric coupling transfer circuit with simple, low cost and good linearity is designed. Finally, this article describes the open-loop SCC method of artificial rainfall automatic rainfall control system and rainfall parameter acquisition block diagram.
