可编程自动化控制器在基坑开挖监测管理系统中的应用

Application of PAC in inspecting and supervising system of foundation pit excavation

介绍了可编程自动化控制器(PAC)在基坑开挖监测管理系统中的应用,从信号调理、数据采集、数据存储方面对硬件进行选择,构建面向仪器系统的周边元件扩展(PXI)硬件平台；就数据的采集、保存以及显示三方面对基于LabVlEW的PAC软件编制作了详细阐述,PAC控制可靠性和稳定性高,适应基坑开挖的工业环境,为工况复杂的系统控制提供参考。

Introduce programmable automation controller(PAC) application in the inspecting and supervising system of the foundation pit excavation.Build the PXI hardware system base on the data modulation,collec- tion and display.Show the software designed of gathering,saving and showing data progress.The character of PAC includes high security,veracity and adapting to industry environment.These lay a base for the control complicated system.
