虚拟仪器将计算机技术与测量技术紧密融合，它在进行环境参数测量时无需使用大量的测量设备，最大限度地降低了开发成本。鉴于此，设计了一个基于虚拟仪器技术的温度测量系统。该系统主要由下位机和上位机两部分构成，下位机通过传感器采集温度信号，经单片机以串口通信的方式传送给上位机，上位机中由LabVIEW软件编写的温度测量系统可实时进行温度的显示与报警。测试结果表明，该设计系统的测量精度较高，操作简单，而且可视性很好。

Since virtual instrument fuses the computer technology and measurement technology closely,does not need more measuring equipments when environmental parameters are measured,and minimizes the cost of development,a temperature mea-surement system based on virtual instrument technology is designed in this paper. The system is composed of the lower computer and upper computer. The temperature signal is collected by the lower computer through sensor,and then transported to the up-per computer through MCU by serial communication mode. The temperature detecting system in the upper computer,written by LabVIEW software,can make real-time temperature display and alarm. The test results show this system has the characteristics of high accuracy,simple operation and good visibility.
