摘要
介绍在LabVIEW软件平台设计虚拟温湿度大气压仪的过程。在软件环境中,通过使用Modbus通信协议和RS485通信接口,采集温湿度大气压仪的相关数据,并对数据进行管理和显示。文中给了硬件连接示意图、数据采集时温湿度大气压变送器模块串口通信参数的设置,并详细阐述了在软件平台上实现温湿度大气压参数的设置方法,分析了虚拟仪器可视显示界面设计过程,并给出了虚拟仪器的软件流程图。
Brief introduction of the design of virtual temperature,humidity and atmospheric pressure instrument on the LabVIEW software platform.In the software environment,through the use of Modbus communication protocol and RS485communication interface,collecting temperature,humidity,atmospheric pressure instrument related data,and manage and display data.This paper give the hardware connection diagram,data acquisition of temperature and humidity atmospheric pressure transmitter module serial communication parameter setting,and elaborate the realization of temperature and humidity setting method of atmospheric parameters in the software platform,analyze the visual display interface design process of virtual instrument,and give the software flow chart of virtual instrument.
