摘　　要：主要利用Labwindows/CVI程序设计语言,来实现风蚀风洞风速监控系统中PLC与PC机的串行通信,并实现变频器的启动、复位和报警等开关量的自动控制,从而大大提高了利用风洞进行土壤风蚀和土地荒漠化研究等的自动化水平。This paper is the use of Labwindows / CVI programming language to achieve serial communication between the PLC and the PC in the wind erosion tunnel’s speed monitoring and control system. And to achieve the inverter’s switch volume automation,such as start,reset,alarm,greatly increased the automation level of soil erosion and land desertification research.
