基于labview的温度检测系统(杨凤鸣)
several group number, then with b ± a, =c,c is is methyl b two vertical box between of ac问题。本设计有两个方面，上位机是在PC平台上运用LabVIEW软件开发检测界面，并且直观的观察温度变化曲线，根据需要还可以以Excel表格的形式，保存检测的历史数据，根据实时采集的温度数据和设定值比拟，提示温度报警；下位机是通过单片机89E52读取温度数据，通过RS-232转USB接口，动如上位机中进行分析处理。
LabVIEW的通信模块NI-，使下位机与LabVIEW通信时可以不通过数据采集卡接收下位机的监测数据，使LabVIEW的灵活性和实用性更好，节约了硬件局部的本钱。

Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured
